Contacting equipment such as trays can handle both mass transfer and heat transfer services. Some processes will simultaneously combine the two. However, using a tray for a dual purpose requires care, as examination of a common combined application — subcooled reflux going to the top tray of a tower — will show.
Many plants will allow the tower overhead temperature to float with the temperature of the utility cooling water or air. Often, the overhead duty removed isn't a major issue because the tower effectively operates with a total condenser overhead. Figure 1 depicts a complex column with this configuration.
If the pressure control system can handle varying overhead drum temperature, the direct effect of subcooling variation is small. The subcooled reflux returns to the tower. In heating up to the bubble point, the subcooled reflux condenses some of the rising vapor. The internal reflux rate inside the tower is higher than the measured reflux rate from the pump to the tower.
The effect of subcooled reflux can be estimated by:
LF = F [1 + (h*- h)/(Heq – h*)]
where LF is the change in liquid flow at the feed stage, F is the total moles of feed (reflux), h is the molar enthalpy of liquid feed at actual column conditions, h* is the molar enthalpy of liquid feed at the column pressure boiling point, and Heq is the molar enthalpy of vapor that would exist in equilibrium with the feed if the liquid feed were at the column pressure boiling point.
As long as the tower internals are designed to cope with the required liquid rate after subcooling, the tower won't flood.
Subcooling also introduces a second issue. Some part of the tray's vapor/liquid contacting area is being used only for heat transfer and condensing the vapor; no equivalent mass transfer of material from the liquid to the vapor occurs. So, in general, if a tray (or height of packing) is required for subcooling, don't take any credit for the tray as a mass transfer device. This isn't always exactly true — a single tray may accomplish all the heating required and then go on to have mass transfer between the liquid and vapor phases. However, it's good practice never to count on trays that are heating subcooled liquids to accomplish any mass transfer.
Returning to Figure 1, we see that a liquid product is drawn from either the sump on Tray 1 or the sump on Tray 2. Due to complex product blending requirements, a liquid side-stream also is taken from the top of the column (Tray 1 or Tray 2) and added to the bottoms product. A vapor side-stream is drawn from below the feed, condensed and added to the overhead product.
Usually, liquid side-draws are some distance down from the reflux return — so changes in reflux subcooling don't have significant impact. Here, however, the correct draw point was only one tray below the reflux and actually varied depending upon the amount of subcooling. Taking liquid from the wrong location could result in significant product quality swings. The solution was to provide an alternative draw point on Tray 2 that can be switched to as needed.
Subcooled liquid feeds (and refluxes) can create both hydraulic and efficiency problems in towers. So, take the safe approach and don't count the necessary trays for heating the liquid as mass transfer trays.

Armpit pain and its causes are the topic of this transcription. If you are suffering from pain under your armpit, here's information will help you deal with it. But let's know a little about armpit's inflammatory pain.
Known as axilla, oxther and underarm, the armpit is a most sensitive part of human body to be influenced easily of all kinds of impact, be it mild or harsh; internal or external. It is armpit's natural sensitivity that provides immense pleasure of libido when licked or played with beloved's finger. How sensitive the armpits are can be fathomed with thermometer to be placed under it to measure our body temperature in fever. Smell of some edibles like raw onion, meat and spices also comes out from sweated armpit. There is no any other part of human body where the smell of freshly consumed food items must be coming from, as naturally. But being susceptible to both external and internal effects, the armpit sustains injuries as well, to be caused due either to uprooting of its hair, or infection.
Causes of Pain in Armpit or Axilla
Following are a few common conditions causing pain in the armpits.
- Uprooting of armpit hair – Uprooting of armpit hairs is one of the major conditions of underarm pain which a maximum numbers of the people do encounter in their life. The underarm hairs in the teenagers is a legitimization of theirs becoming physically capable of performing everything a young adult is supposed to do. It is imperishable significance of libidinousness, highlighted in the erotic poems, which makes the male-arms impregnable habitat for a girl. But the hairs of armpits, if not cleaned or shaven periodically may become a cause of underarm pain. Underarm hair if uprooted causes injuries and infection affecting the respective person with armpit pain.
- Excessive sweating – It is one of the common axillary intertrigo, affecting the people with a kind burning sensation in their armpits, just akin to a pain. As sweat is caused due either to physical labor or hot environment, the armpit suffers from a friction, heat and moisture which torment the affected person with irritation, wrongly depicted as pain in their armpits. [Read more on how to get rid of armpit sweat.]
- Itching in underarm – Itching in the armpits caused due to hot climatic condition if scratched with finger-nails for respite causes inflammation under the axilla.
- Infection in the armpits – Infection in the armpits also causes pain. There may be several conditions causing infection within the armpits, such as uprooting of armpit hair, wearing of sweated bush-shirt, working under scorching heat perspiring for long. As the armpit happens to be sensitive to the temperature, moisture and friction, it gets easily affected of infection, causing thereby pain. Bacterial infection, yeast infection, and fungal infection also are the causes of this condition.
- Swelling of lymphatic glands – It is one of the major conditions tormenting the people with tremendous pain in their armpits. It may affect someone due either to exertion within the armpits or cancer. Travelling in a train or car hanging one arm out of window and shifting entire load under the armpit causes lymphatic glands to swell extensively and torment the person with pain in armpit. The pain in the armpit caused due lymphatic swelling should vanish within a few days. If it doesn't, you should consult with the doctor as it is a vivid sign of cancer as well.
- Pectoral muscles – It is the chest-muscle which also causes pain in the armpit if stretched extensively. Situated just over the ribs, it happens to be susceptible to injurious impact, during the workouts if someone doesn't prepare his body for exercise by warming it up and starts abruptly the workout. This is a condition causing pain in the armpits.
- Cysts or spherical swelling – It is a critical health condition associated with swelling in the lymphnodes in arms. Recognized as the lumps under armpits, the cysts' emergence is supposed to be a serious health condition, needed to be brought into doctor's notice. Monitoring the lumps or cysts through biopsy-test the doctor easily determines which type of treatment to administer to the affected person.
- Deodorant – Market is flooded with variety of deodorants which for the skin of your armpits may not be compatible anymore. Regular usage of such type of deodorants may cause an allergic reaction and thus may affect your armpits with itching, burning sensation or pain as well.
- Close shaving – Using electric shaving machine or shaving the armpit hair too closely by moving razor in opposite direction causes the bruise in axilla which triggers inflammation and pain in the armpits.
- Synthetic attire – It is the allergic reaction due to synthetic garments that also causes pain on your armpit. The individuals, allergic to clothing, experience inflammation under their armpits due to friction of cloth on skin. In order keep all the chances of pain in the axilla or armpits you should wear the hypoallergenic attire.
- Tight clothing – In modern era the youths prefer to wear skin-tight garments like tight top and jeans. And it is the tightness of their tight T-shirt which affects blood flow under their armpits following which a pain is emerged in their armpits.
- Randomize physical activities – Randomized sporty activities stretch the muscles and causes in this way pain within the armpits. Badminton, volleyball and kite-flying also are the games causing the pain under armpit.
- Blood cancer – It is a malignant disease, affecting a maximum numbers of the people in the world with unwanted growth of skin under their arms which torments them with inflammation and pain in their armpits.
- Shingles – It is a viral disease, affecting the skin armpit with inflammatory pain. Such condition may affect the people with pain in their armpits. The chicken pox virus contributes in such condition causing small blisters over the skin of armpit which torments the people with armpit pain.

Enable file system journaling on Solaris 7 and 8
Solaris 7 and 8 include a native implementation of file system journaling. This feature, known as "intent logging" or just "logging" enables FASTER file system operation and FASTER system boot. It's trivial to implement and safe to use. The new logging feature is an option to the Unix File System (UFS), which is the standard file system for all disk partitions on SUN servers, except for partitions holding swap space. By default, the journaling option is disabled. Logging is enabled on a per file system basis, and it can even be enabled on / (root file system) and other operating system partitions. Background Solaris UFS logging works by allocating space from the file system's free blocks. Within that space, all metadata changes to the file system are written. Metadata includes directory and I-node information but not file data blocks, essentially everything but the actual data within the file. So, for example, a "file create" modifies the directory structure and allocates a new I-node, and those activities are written to the logging space. Once the metadata changes are made to the logging area, the system is free to perform other operations to the file system. In the background, the information in the log is flushed to the file system and updates the appropriate directory and Inode structures, completing the file system operations. The logging data is written sequentially within the log space. It's therefore much faster for the operating system to complete metadata changes via logging and background flushing than by directly modifying the metadata (via random I/O) spread across the disk. The size of the logging space is based on the size of the file system, and equals 1 MB per 1 GB of file system space, up to 64 MB. The space is used as a circular log: if the log space is about to fill up, new metadata change requests are paused while the log is emptied. As changes are moved from the log to the file system, that log space is made available, and new metadata changes can be written to the logging space. Usually with UFS, if the system crashes during any file system operation, the entire system must have its consistency checked via the fsck command. That command can take several minutes per file system because it checks all metadata and file data to ensure the structures are correct, free, and used, and that the I-node block counts are correct. It also confirms that the free space available is current, repairs inconsistencies, and occasionally requires manual intervention to fix
large problems. Files and even directories can be lost, depending on the operations occurring at the time of the crash. Because metadata changes are made first to the log space rather than to the file system, the consistency check for a logged file system after a crash is a simple and fast operation. The system evaluates the logging data and determines which changes had completed against the underlying file system, which had yet to start, and which were in progress. Those completed or not yet started are removed from the log, and those partly completed are either undone or completed. If there's sufficient data in the log to complete the operation, it's completed. Otherwise, the changes made are removed from the underlying file system. People familiar with database operation will recognize the similarity between database transaction processing and the activities here. The end result is that the underlying file system is consistent, and no thorough consistency checking is needed. That operation completes in a few seconds per file system. Using logging Starting with Solaris 7, there's a new logging option to the mount command and in the /etc/vfstab system configuration file. Logging only appears in a couple other places within Solaris. The mount command shows which partitions are mounted and lists logging in the options fields for each partition on which logging is enabled. Finally, at system boot time, the fsck phase reports per partition whether each is stable, logging, or being checked. There are no other status commands available to determine the state of logging. A = Device to mount B = Device to fsck C = Mount point D = Filesystem Type E = Fsck pass (unimportatnt with logging) F = Mount at boot G = Mount options # -----------------------------------------------------------------#A B C D E F G # -----------------------------------------------------------------fd /dev/fd fd - no /proc /proc proc - no /dev/dsk/c0t0d0s3 swap - no /dev/dsk/c0t0d0s0 /dev/rdsk/c0t0d0s0 / ufs 1 no logging /dev/dsk/c0t0d0s6 /dev/rdsk/c0t0d0s6 /usr ufs 2 no logging /dev/dsk/c0t0d0s1 /dev/rdsk/c0t0d0s1 /var ufs 3 no logging /dev/dsk/c0t0d0s7 /dev/rdsk/c0t0d0s7 /home ufs 4 yes logging /dev/dsk/c0t0d0s5 /dev/rdsk/c0t0d0s5 /opt ufs 5 yes logging /dev/dsk/c0t8d0s0 /dev/rdsk/c0t8d0s0 /u01 ufs 6 yes logging /dev/dsk/c0t9d0s0 /dev/rdsk/c0t9d0s0 /u02 ufs 7 yes logging

Logging increases performance, decreases fsck time, removes the risk of a file system corruption, can be used on all UFS partitions (including root), and is free.
Solaris Syslog Daemon Debugging
The log system messages daemon syslogd reads and forwards system messages to the appropriate log files and/or users, depending upon the priority of a message and the system facility from which it originates. The configuration file /etc/syslog.conf controls where messages are forwarded. The syslogd daemon ignores any faulty entry in /etc/syslog.conf, specially spaces instead of tabs are not recognized by syslogd. Therefore always check the entries in /etc/syslog.conf in the debugging mode of syslogd.

Evidence of improved detection using integrated 2D and 3D mammography provides opportunity for Australia to lead screening trials
The STORM (Screening with Tomosynthesis or Standard Mammography) trial, from a team of Italian and Australian researchers, reports the world's first completed population breast screening trial of integrated 2-dimensional (2D) and 3-dimensional (3D) mammography.1 Using breast tomosynthesis, a pseudo-3D derivative of digital mammography, in combination with 2D mammography, STORM researchers found that breast cancer detection was significantly increased when screen-reading was performed using integrated 2D and 3D mammography compared with 2D mammography alone (Box).1 The trial also showed that this screening method could significantly reduce false-positive results (Box). These data provide evidence that integrated 2D and 3D mammography would enhance breast screening performance measures, and are consistent with the interim findings of another population screening study conducted in Oslo, Norway, using the same mammographic technology.2

text: Governor and UNC Founder William Davie Died November 5, 2016 On November 5, 1820, soldier, politician, and founder of the University of North Carolina, William R. Davie died at the age of 64. Davie graduated from the College of New Jersey (later Princeton) in 1776 and moved to Salisbury, N.C., to study law. Davie had a brief military career in _PHONE_, but was wounded. Later, he organized cavalry, and mounted infantry and embarked on a campaign of partisan attacks in the Carolina backcountry. Around 1786, Davie built a house in Halifax that still bears his name. He would represent Halifax in the General Assembly off and on for the next ten years. Davie was selected to be one of North Carolina's five delegates to the Confederation Congress of 1787, and he campaigned for the Constitution's ratification. At the 1789 convention in Fayetteville that ratified the Constitution, Davie introduced a bill to charter a state university. As founder, he guided the university through its formative years. Elected governor of North Carolina in 1798, Davie went on to represent the United States in treaty negotiations, eventually retiring to his plantation in South Carolina where he died.

will turn to shame or guilt can be shaped by the organisation itself, because feelings of shame and guilt are essentially mixtures of a simple affective element (a raw feeling) and a cognitive process (a 'knowing', I guess).
The categories of Bullshit Jobs
Bullshit jobs, in my view, come in the following flavours (the list continues to grow):
1. Template populators: A template is an abstract structure or order into which relatively simple information or actions can be inserted in order to produce complex but standardised outputs, meeting the template designer's specifications. When you prepare statutory financial reports or regulatory returns, write contract tenders (or invitations to tender, for that matter) for the private or public sectors, if you manage a standardised 'evaluation', 'impact assessment', or 'consultation' process, if you're a UK solicitor involved in conveyancing, a health & safety inspector, or an HR employee taking applicants through a structured behavioural interview, then you are a template populator.
Templates allow complex processes to be standardised and parcelled out, so that individual populators can be allocated tasks they are able to perform, even if they are incapable of efficiently carrying out the whole process. The entire task can thus be performed with the lowest possible level of skilled labour input while meeting the given specification - not what the client wanted necessarily, but what they can be proven to have asked for.
Templates create and protect elites in two ways. First, by making the work of the skilled individuals who design templates scalable. The designer of the template creates a saving by substituting more skilled (designer) labour with less skilled (user) labour and reducing (user) distraction - thus making unskilled (user) labour more productive and releasing skilled (designer) labour to more productive uses. The more they can effectively 'own' the template, the more the designers of the template can capture at least some of this saving as rents.
Second, a template allows the extraction of rents by insulating both its designer and their immediate reports (middle management) from risk, at the expense of pretty much everyone else. After all, a template approved by the principal is almost incapable of producing an outcome the agent can get into trouble over. Which is why, for instance, audit firms rarely get into trouble every time a business they audit fails spectacularly.
When designers aren't effectively able to keep users from replicating their valuable templates elsewhere, it is still possible to restrict usage of the templates, by law or convention, to a relatively small number of users. These user-designers are known as professionals, and they are forced to share the collective rents extracted through templates fairly equally.
2. Junior Lobbyists: a Senior lobbyist in the wider sense is a person who creates 'value' for a constituency by bending the coercive powers of the state in their favour - delivering legislation or, even better, institutions, that allow them to either capture rents, or avoid conceding them to other parties. A corporate lobbyist is only the most obvious example. But the sprawling 'policy' industries of the Anglo-saxon world, the corporatist institutions of Europe, and the well-connected mega-corporates of Asia and Africa, are the preserve of senior lobbyists as well.
Now, a junior lobbyist does none of these things. Junior lobbyists create 'value' by supplying the senior lobbyist with legitimate means of getting close to the people they need to influence, and overcoming initial resistance. They create audiences, venues and props that enable the senior lobbyist to do their job.
Through their work, the constituency cross-subsidises other constituencies' senior lobbyists in return - especially once one considers that government ministers are themselves senior lobbyists to some extent, and their department staff are themselves junior lobbyists.
Finally, the existence of junior lobbyists provides reassurance to their constituents, who typically cannot observe the senior lobbyists at work, that their money is being spent in their best interests.
3. Outsourced compliance clerks, and their handlers: People usually speak of 'compliance' if they are in a regulated environment, and a specialist department has been given the role of checking that the business can be demonstrated to toe the line or better yet, stay off the regulator's radar altogether. I'm not too worried about them because they are essentially Template populators as per no. 1 above.
But compliance in practice can be more about internal policies than external regulations. Ever worked in a company that employs frequent travellers? I have. Our travel was ostensibly booked by a departmental PA, but in reality the poor lady was merely the first point of contact - she was required, by company policy, to forward our travel requests to a travel agent, who then came back with a quote. In all my years working for the company I was never able to get a quote from them that I couldn't beat with a simple search. They were costing, rather than saving, money. So the company, and our customers were getting negative value.
Why did this job exist? Because back in the day someone decided (correctly) that our department was spending too much on travel, with no one checking whether the travel was actually value-for-money and that people weren't treating themselves to the odd cheeky upgrade. The tough way to fix this would have been to speak to line managers and tell them it's their responsibility to keep travel costs down. Even better - give them a team budget each and end the tragedy of the commons. The easy way was to write up our policies, forward them to a contractor and say 'don't book anything that isn't compliant.' The travel agent isn't saving us money, or even making us waste less money. They simply ensure that we waste only within the boundaries of what is approved; and they skim a little bit of value out of this.
Our departmental PA (otherwise a highly competent person) wisely moved on to a better job. She didn't mention the word 'bullshit' but I think it was mostly out of courtesy.
4. Organisational Placebo Buttons
A placebo button is a button (e.g. on an elevator or a train door) that isn't actually wired to do anything, but exists in order to create an illusion of control. Placebo buttons exist because automation has advanced faster than the users it seeks to serve - and its purpose is to keep the latter content.
Organisational placebo buttons are created when senior decisionmaking bodies in organisations are stripped of their power or are forced to capitulate to an executive office. Alternatively they may be needed when decisionmaking bodies are ultimately powerless but their memberships aren't ready to admit this. This doesn't usually happen in purely commercial organisations, but it is very likely to happen in any kind of membership organisation, where the tension between management and membership needs to be management. The 'placebo button' is a person whose job it is to liaise with the fallen ex-decisionmakers for the sole purpose of assuring them they still matter. The purpose of all this is to allow management to run the organisation according to its own interests and yet appear to be paying close attention to the membership, for whom the organisation supposedly exists.
The placebo button job holder serves management of course, but, as long as they are junior enough, will tend to be flattered by the opportunity to rub shoulders with the senior'stakeholders' they are meant to reassure and soak in their wisdom. Once again, the progression is asymptotic - the placebo man or woman will almost certainly never become one of the stakeholders, or one of the senior manager rentiers they are covering for.
5. Scar tissue
Ursula LeGuin's The Disposessed offers an interesting thought on how anarchist societies might fail; in LeGuin's world, crises, in her case natural but I guess also man-made ones, can have a lasting effect on even an ideal anarchist society. They do this by building a'scar tissue' of control around the affected area, in order to resolve the crisis quickly and prevent it from arising again. The scar tissue never fades completly, and successive crises only add new, differently shaped layers to it. Commercial businesses, public sector bodies and non-profits act in much the same way.
When a product fails to click with its intended audience, you know a new layer of market research will e required before any further products get approved. When a newsletter or report prompts an angry response from important people, you know future editions will tend to require additional senior sign-off. When colleagues complain about being excluded from meetings, you know the organiser's response will be to copy them pre-emptively into everything remotely of interest in future.
Everyone's job incorporates scar tissue over time - eating away at the essence of their jobs even if they show no obvious signs of being bullshit jobs. The more'stakeholders' and 'internal clients', the greater the potential for crises, and the faster the buildup of scar tissue. The scar tissue protects senior management by helping the organisations draw less of its stakeholders' attention - which is essential if they are to continue to believe they call the shots.
Some of these jobs are set up in order to artificially create an 'owner' for a diffuse risk, or an owner for the metrics of said risk. Suppose you hire somebody, a third of whose job it is to 'co-ordinate' action on hospital waiting hours. They will collate, analyse and present figures on hospital waiting hours; they will 'liaise' (that word again) with people who actually can make a difference to the situation. But when responsibility is diffuse, these people are likely to be too senior, too remote, or too culturally silo-ed to reach. The 'waiting hours' person will know within a month that their job is not to improve

Video Explaining How to Insert Special Symbols
This video explains 7 ways to insert a special symbol into an MS Office application (e.g., Word) or a website using HTML, CSS, or JavaScript:
How To Insert the ⇀ Symbol
(Method 1) Copy and paste the symbol.
Click on the ⇀ symbol from the table above. Press the "Copy" button, and then paste the symbol into your document.
(Method 2) Use the "Alt Code."
The Alt Code for ⇀ is Alt 8640. If you have a keyboard with a numeric pad, you can use this method. Simply hold down the Alt Key and type 8640. When you lift the Alt Key, ⇀ appears. ("Num Lock" must be on.)
(Method 3) Use the HTML Decimal Code (for webpages).

Symbol: ⇀
(Method 6) Use the HTML Hex Code (for webpages and HTML canvas).
HTML TextOutput
⇀
On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x21C0 to place the ⇀ symbol on your canvas. For example:
JavaScript Text
const x = "0x"+"21C0"
ctx.fillText(String.fromCodePoint(x), 5, 5);
Output
(Method 7) Use the Unicode (for various, e.g. Microsoft Office, JavaScript, Perl).
The Unicode for ⇀ is U+021C0. The important part is the hexadecimal number after the U+, which is used in various formats. For example, in Microsoft Office applications (e.g. Word, PowerPoint), do the following:
TypeOutput
021C0
[Hold down Alt]
[Press x]
(Note that you can omit any leading zeros.)
In JavaScript, the syntax is \uXXXX. So, our example would be \u21C0. (Note that the format is 4 hexadecimal characters.)
JavaScript TextOutput
let str = "\u21C0"
document.write("My symbol: " + str)
My symbol: ⇀
(Method 8) Use an Image (for various).
HTML TextOutput

Access log level 4 enables logging for internal operations which log the details of the search being performed, and the search base, scope, filter, and requested search attributes.
The connection description, in this case conn=Internal, indicates that the connection is an internal connection. The operation number op=-1 indicates that the operation was initiated internally.
The options description, in this case options=persistent, indicates that a persistent search is being performed. Persistent searches can be used as a form of monitoring. They can be configured to return changes to given configurations when changes occur.
The Sun ONE Directory Server 5.2 access log distinguishes between persistent and regular searches. Some earlier Directory Server releases did not make this distinction.
In Code Example 8-4, both access logging level 512 and 4 are enabled, which results in both internal access operations, as well as entry access and referrals being logged.

Common Connection Codes
A connection code is a code that is added to the closed log message to provide additional information related to the connection closure. Common connection codes include:
A1=Client aborts the connection.
B1=Corrupt BER tag encountered or BER tag is longer than the nsslapd-maxbersize attribute value. For further information about this configuration attribute, see "nsslapd-maxbersize (Maximum Message Size)".
If BER tags, which encapsulate data being sent over the wire, are corrupt when they are received, a B1 connection code is logged to the access log. BER tags can be corrupted due to physical layer network problems or bad LDAP client operations, such as an LDAP client aborting before receiving all request results.
B2=BER tag is longer than the nsslapd-maxbersize attribute value. For further information about this configuration attribute, see "nsslapd-maxbersize (Maximum Message Size)".
B3=Corrupt BER tag encountered.
B4=Server failed to flush data response back to client.
P2=Closed or corrupt connection has been detected.
T1=Client does not receive a result within the specified idletimeout period.
T2=Server closed connection after ioblocktimeout period was exceeded.
U1= Connection closed by server after client sends an UNBIND request. The server will always close the connection when it sees an UNBIND request.

water shrew
Sorex palustris
What do they look like?
Water shrews are relatively large shrews with males tending to be longer and heavier than females. The total length of a water shrew can range between 130 and 170 mm, and the weight ranges from 8 to 18 grams. Although the color of the fur may be variable, it is generally black or grey-black on the back and a silvery-grey on the belly, but appears more black in the winter and becomes more brown in the summer. Water shrews can have tails varying from 57 to 89 mm in length. The tail is dark above and white or grey below. The hind feet (18 to 21 mm) are larger than the fore feet and have a trim of 1 mm long stiff hairs on the toes and the inner and outer sides of the feet. A fringe of smaller stiff hairs is also found on the fore feet.

 - male larger
 - Range mass
 8 to 18 g
 0.28 to 0.63 oz
 - Range length

Where do they live?
Water shrews are found throughout Alaska and Canada to the northern mountain regions of the United States.
What kind of habitat do they need?
Water shrews are common inhabitants of northern forests. As the name would suggest, water shrews are often found around streams and other aquatic habitats. Moist areas surrounded by heavy vegetation, logs and rocks are preferred.
 - Aquatic Biomes
 - lakes and ponds
 - rivers and streams
How do they reproduce?
The breeding season is usually from December to September. In one breeding season, two to three litters may be produced, each litter ranging from 3 to 10 offspring. Females are pregnant for three weeks and then birth takes place in spring or summer. Males reach sexual maturity in the winter following birth. Most females, like males, become sexually mature in winter and breed in late winter or early spring, but there have been reports that some reproduce during their first summer.

How long do they live?
Water shrews are short-lived. The typical life span of a water shrew is about 18 months.
 - Average lifespan
 Status: wild
 18 months
How do they behave?
Water shrews are solitary creatures, active throughout the day and night. When active, water shrews dive and swim in water to forage for food. Water shrews can dive year-round, even in cold bodies of water in the winter. Each dive can last from 31.1 to 47.7 seconds. In water, the fur is lined with a layer of air that reduces their heat loss by 50% and makes them float. Therefore, when water shrews swim or dive, they must paddle hard to keep from drifting to the surface. The hind feet, and the stiff hairs on them, propel them through the water. Immediately after swimming, water shrews dry off their fur using the hind feet. Besides swimming, some water shrews have been seen walking on the surface of water. It has been suggested that water shrews can walk on water because they can trap air bubbles in the stiff hairs of their feet.
Nests of water shrews are usually about 8 cm in diameter and are either new nests or reconstructions of old nests built from dried plant material in tunnels or under hollow logs. Water shrews dig their own tunnels by digging with the fore feet and throwing out soil with their hind feet. New nests are built using their feet and legs to form a depression and the walls of the nest shaped with the snout.
Water shrews are aggressive and fighting is common between them. Males and females are equally likely to fight. Most encounters are short but may be intense. Fights between two individuals usually start off with each giving off high pitched squeaks followed by standing on their hind legs to expose their light-colored bellies. If neither shrew retreats after these displays, they will begin to slash each other with their teeth as they wrap up into a tight ball. Head and tail injuries often occur. These fights have not been proven to be territorial.
How do they communicate with each other?
Sensory abilities of water shrews are not well understood. The whiskers and the snout are thought to serve the purpose of locating prey. During explorations water shrews release continuous high pitched sounds. This has led people to believe that water shrews echolocate. Water shrews give off a strong, sometimes nauseating odor, suggesting that they have a well-developed sense of smell. These odors may help them attract mates or to recognize other water shrews.
What do they eat?
Water shrews are, for the most part, insectivores. Diving to the bottoms of streams or other water habitats, they forage for aquatic insects, especially for the larvae and nymphs of caddisflies, crane flies, mayflies, and stoneflies and occasionally for small fish . Besides aquatic animals, they will also feed on land for flies, earthworms, snails, fungi and green vegetation. Once it's caught, the food is held by the fore feet and torn to pieces using the teeth through upward thrusting of the head. Water shrews can live without food for up to 3 hours, but captive shrews have been found to feed almost every 10 minutes. The amount of food required by a water shrew has been estimated to be 0.95 g/day.
 - Animal Foods
 - fish
 - insects
 - mollusks
 - terrestrial worms
 - Other Foods
 - fungus
What eats them and how do they avoid being eaten?
Water shrews dive and swim to escape from predators like garter snakes, hawks, owls and weasels.
 - These animal colors help protect them
 - cryptic
What roles do they have in the ecosystem?
Water shrews are important predators of the insects on which they feed, and they are an important food source for the predators listed above.
Do they cause problems?
The water shrew has no known negative effects on humans.
Are they endangered?
Water shrews are widespread but rarely captured.

Transnational mobility under the ESF in Germany
1. Brief description of programme
Against the backdrop of positive developments on the German labour market over the last few years, the prospect of finding work or an apprenticeship has also improved for people who have difficulties in accessing work or training for individual or structural reasons. However, at the moment this group benefits less from the positive developments on the labour market than the German average. Often there are multiple reasons for why members of this group fail to begin employment or an apprenticeship. These include long-term unemployment, a lack of or few skills learned at school or during training, poor language skills, health issues, a precarious financial situation or problematic living conditions. Often several of these difficulties coincide. Youth and young adults, in particular, if left to fend for themselves, often fail to enter the labour market or to start an apprenticeship. This is especially true of migrants.
As part of the "Federal ESF Integration Directive" programme of the Federal Ministry of Labour and Social Affairs, the priority area "Integration through Exchange" promotes transnational measures aimed at reaching and activating the participants in an effort to gradually and sustainably integrating them into work or training. Measures aimed at helping people to (re)-enter school to acquire a school-leaving certificate are also eligible for receiving grants.
The key component of the transnational measures is a (two to six months) supervised stay abroad with in-company training (supervised practical activities combined with application-oriented classes in a work-related context). It is part of a pedagogical concept geared towards the labour market that includes intensive, individualised pre-departure preparations and follow-up activities in Germany.
By involving job centres or employment agencies in the projects, the transnational measures are designed to dovetail with the standard support schemes for integration (Social Code Books II and III), and they are designed to be used as a component of the participant's individual integration plans. Therefore, the follow-up period is of particular importance as well, as it is essential to respond to the insights and the personal development of the participants early on and to sustainably harness them for seamless integration into the labour market.
In the framework of the transnational measures, the following project components are eligible for receiving grants:
- preparatory phase of the transnational partnership,
- participant recruitment and participant preparation,
- participant stay abroad,
- follow-up phase
2. Target group
In the priority area "Integration through Exchange", transnational mobility measure should address the follow target group:
Youth and young adults aged 18 to 35,
- who face difficulties in accessing work or training for several individual or structural reasons, such as long-term unemployment, low levels of school performance/vocational skills, or a migration background, and
- who cannot or can no longer be successfully reached with the integration benefits provided by the job centres (Social Code Book II) or the employment agencies (Social Code Book III).
3. ESF Thematic Priority
The Operational Programme of the Federal Government for the European Social Fund (ESF) for the funding period 2014 - 2020 serves as a legal basis for the programme. Support under the Federal ESF Integration Directive (which includes the support for mobility measures within the priority area "Integration through Exchange") comes under the intervention category of Article 3 (1b) of regulation (EU) No 1304/2013 "promoting social inclusion, combating poverty and any discrimination" i) "Active inclusion, including with a view to promoting equal opportunities and active participation, and improving employability".
4. Intended timeline for call of proposals
Date of launch of regional call: October 2014 (call is closed)
Ongoing projects from June 2015 until December 2021


text: This paper addresses description and kinematic analysis of a micromanipulation system based on revolute typeflexure joints. It is a five-bar planar parallel manipulator dedicated to applications requiring micro/nano scale motion. The forward kinematics problem is formulated and then solved by employing two separate approaches; (i) linearising the trigonometric functions (TF) and (ii) employing an approximate method based on linearising generalised velocity relationship for small joint space and Cartesian space displacements. Further, the velocity of the manipulator in Cartesian space is determined and compared to the results obtained from (i) linearising TF in the Jacobian matrix and, from (ii) using a constant Jacobian matrix. Numerical results prove that linearising TF in the kinematics equations and Jacobian matrix gives results close to the exact results. Using a constant Jacobian approach for analysing kinematics of micromanipulation systems contradicts the order of accuracy expected from such systems.

Plant saucers with wheels are great for indoor gardening. If you've ever tried growing plants inside, you know it's difficult to keep track of where each pot goes. That's why plant saucers with wheels are so useful. Instead of digging around in pots and soil, you simply wheel the saucers into position. Then, you fill the saucers with fresh soil and plant seeds. Once the seedlings sprout, you can transplant them into larger containers.
Using a wheeled planter caddy makes planting and watering your garden a breeze. First, you set the caddy near your window. Next, you fill the caddy with soil and plant seeds. Afterward, you wheel the caddy outside and let the sun dry the soil. Lastly, you transfer the plants to bigger containers. Now, you only have to worry about watering once per week!
Yes, a wheeled planter caddy is far superior to traditional tools. Traditional tools require constant attention. You must dig holes, mix soil, and water your plants. All of which takes time and effort. Meanwhile, a wheeled planter caddy requires no physical labor. Just wheel the caddy to the right spot and wait for the plants to grow.
Of course, you can grow plants indoors without a wheeled planter caddy. But, it's going to be extremely challenging. You'll have to constantly monitor your plants' growth and adjust the amount of light they receive. Otherwise, your plants might end up stunted and unhealthy. Furthermore, you'll have to deal with pests and diseases.
It depends on whether you intend to grow vegetables or flowers. Vegetables require lots of light whereas flowers prefer low levels of light. Thus, you'll need two separate sets of lighting fixtures. Additionally, you'll need to purchase additional accessories such as fertilizer, pest control products, and insecticides.
Plant saucers are great tools for growing plants indoors. If you've ever tried to grow plants inside before, you know it's difficult to achieve success. One reason why indoor gardening isn't so successful is because of poor lighting conditions. Plants need bright light to thrive. Unfortunately, artificial lights only produce low levels of light which doesn't give plants enough nutrients. Additionally, the lack of natural air circulation makes it hard for plants to breathe properly.
Saucer wheeled planters are ideal for growing plants indoors. Not only does a saucer wheeled planter create good lighting conditions, it also creates proper airflow. Airflow promotes healthy growth by allowing oxygen into the soil where roots live. Furthermore, the saucer wheeled planter prevents moisture build-up around the base of the pot. Moisture buildup causes root rot and disease. Lastly, saucer wheeled planters are convenient. Because they're lightweight, you can transport them anywhere you go.
There are two main types of saucer wheeled planters. First, there are round pots. Round pots are perfect for growing herbs and vegetables. Second, there are square pots. Square pots are suitable for growing flowers and houseplants. Both types of saucer wheeled planters are available in several designs and finishes.
Before choosing a saucer wheeled planter, think about the type of plants you'd like to grow. Then, choose a model based on its design and color scheme. Choose a saucer wheeled planter with ample drainage holes. Drainage holes let excess water drain away from the bottom of the pot. Make sure the saucer wheeled planter has sturdy handles. Handles enable you to lift the planter easily. Look for a saucer wheeled planter with a non-skid coating. Non-skid coatings reduce slipping hazards.
Choose a saucer wheeled planter that suits your needs. Consider factors such as durability, style, and price. Durability refers to how well a product holds up over time. Style refers to the overall appearance of the product. Price refers to how much money you'd like to invest in the item.
Plant saucers with wheels are great additions to any garden. If you've got limited space, these wheeled pots are perfect for growing plants indoors. But before purchasing a pot, it's important to know which features matter most to you. Here are three key factors to think about when choosing a plant saucers with wheels.
Size - How big does your pot need to be?
Style - Does your house have a modern style or traditional design? Modern homes favor sleek lines and simple designs. Traditional houses prefer ornate details and classic styling.
The biggest factor to consider when selecting a plant saucers with wheels is its overall size. Smaller containers are ideal for indoor gardening. Larger pots are suitable for outdoor gardens where you'd like to grow taller specimens.
Next, choose between round, square, rectangular, or oval pots. Round pots are considered the easiest shape to maneuver around. Square pots are good for growing tall plants. Rectangular pots are versatile and can accommodate both short and tall plants. Oval pots are shaped like ovals and are excellent choices for growing fruits and vegetables.
Finally, select a plant saucers with wheels based on your personal preference. Contemporary homes favor minimalist designs. Traditional homes favor detailed patterns and intricate carvings. Choose a style that matches your decorating preferences.
Plant saucers are useful tools for growing plants indoors. They are especially helpful for beginners who want to grow houseplants. If you've never grown anything before, it's important to start slowly so that you don't overwhelm yourself. That way, you'll learn which plants thrive well inside and which ones don't. Once you know what works and doesn't work, you can begin experimenting with larger pots and bigger plants.
There are several different types of wheeled plant saucers available. Each type has its own advantages and disadvantages.
Saucer Pots - These saucers are ideal for smaller indoor plants. Their shallow depth makes them perfect for starting seeds. Additionally, they're lightweight enough to carry around. However, they lack drainage holes. Thus, they must be filled with potting soil prior to planting.
Deep Saucer Pot - Deep saucer pots are great for taller plants. They hold plenty of soil and drain quickly. However, deep saucers are difficult to transport. Because of their weight, they're only suitable for outdoor gardens.
The choice between a saucer pot and a caddy depends largely upon personal preference. Both types of containers are versatile and effective. Ultimately, the decision comes down to whether you prefer stability or mobility.
One advantage of using saucer pots is that they're inexpensive. Compared to caddies, they're significantly cheaper. Furthermore, they're easy to assemble. All you need is a flat bottomed container and a lid. Then, simply fill the saucer pot with potting soil and plant your seedlings. Afterward, cover the hole with soil.
On the flip side, saucer pots are limited by their design. Since they're shallow, they're prone to drying out. Additionally, they lack drainage holes. Thus, they must be filled with potting soil prior to planting. Lastly, saucer pots are hard to repot once they become rootbound.

Title: Anaemia in cancer patients undergoing radiotherapy: Our experience at the National Hospital Abuja, Nigeria
Biography: Chinedu S Aruah
Introduction: More than 50% of cancer patients will receive radiotherapy in the course of their therapy. Anaemia is the most common haematological complication in cancer patients. The cut-off value for anaemia varies from centre to centre, but Hb of 10 g/dl is a borderline value and administration of radiotherapy without adequate haematological support may tilt the patient into clinical anaemia.
Objective: To study the impact of radiotherapy on the haemoglobin level of cancer patients undergoing therapy.
Materials & Methods: A total of 63 patients with solid tumours with intent for radical treatment were recruited within a period of 8 months. Informed consent of participants was obtained and demographic characteristics of the cancer patients and their various oncologic diseases were gathered. Baseline or pretreatment Haemoglobin (Hb) was measured on the first day of consultation. Patients were simulated and treated with linear accelerator. Their Hb level was measured once every 2 weeks during therapy. The blood film pictures of the patients were examined in the course of treatment. The whole process was terminated after 3 consecutive Hb reading or after week 6. Anaemia was classified for this study into: Less than 10 g/dl-severe anaemia; 10–10.9 g/dl -moderate anaemia; 11–12 g/dl-mild anaemia;> 12 g/dl-no anaemia (Normal)
Results & Data Analysis: Data collected was analyzed using a standard statistical package for social science (SPSS) version 10. Out of 63 cancer patients, 92.1% were female and 7.9% were male. Age range was 25–75 years, with median age of 50 years. Breast 47.6% (30) was commonest site of tumour. 74.6% (47) presented with stage III disease. Prevalence of anaemia in the study was 42.9%. At the end of therapy, 55.6% (63) cancer patients had their Hb level between 11.52–12.13 g/dl. At P-value > 0.05 there was no statistical significance on distribution of mean Hb, standard deviation based on sex and treatment type.
Conclusion & recommendation: Prevalence of anaemia in cancer patients undergoing radiotherapy was 42.9% as shown by the blood film. However, at 95% confidence interval (95CI) radiotherapy had no significant impact on Hb level, hence Hb: 11.52 –12.13 g/dl at the end of therapy. We recommend Hb of 11 g/dl as irreducible minimum level for cancer patients undergoing radiotherapy in Nigeria Oncology Centres.


NSScriptCommand. We'll add that method to a new source file "Scripting_Additions.m" that will contain all of the extra code we add to Sketch.
Step 3: Map the command and its arguments to your native language. In _URL_.terminology, add this at the bottom:
 "Commands" = {
 "OpenFile" = {
 "Name" = "openfile";
 "Description" = "open a file";
 "Arguments" = {
 "FileName" = {
 "Name" = "at";
 "Description" = "The file to open should follow, quoted";
 };
 };
 };
 };
Step 4: Write the method handleOpenFileCommand:
Add a new source file to "Other Sources" suitcase in ProjectBuilder, Scripting_Additions.m. We'll use the powerful "Categories" mechanism of Objective C which lets you add to and override methods of existing classes. The override part is tricky though - if more than one category of a class has an alternate implementation of a method, it is indeterminate which method will get called. So use categories with care!
Since NSApplication handles the "OpenFile" command, we implement a category of NSApplication:
@interface NSApplication(Scripting_Additions)
- (id)handleOpenFileCommand:(NSScriptCommand *)command {
 // ask the command to evaluate its arguments
 NSDictionary *args = [command evaluatedArguments];
 NSString *file = [args objectForKey:@"FileName"];
 // if we don't have a file argument, we're doomed!
 if (!file || [file isEqualToString:@""]) return [NSNumber numberWithBool:NO];
 // ask the Application delegate to do the work:
 return [NSNumber numberWithBool:[[self delegate] application:self openFile:file]];
}
@end
Note how the script command knows how to evaluate itself and its arguments, and we just have to check the dictionary for the file name via the key "FileName", same as in the Arguments section of the command definition.
To take advantage of more object oriented (OO) magic, namely the ability for an application to open files dragged on the application tile or via services, we'll implement application:openFile: in a DrawAppDelegate category. And using the Cocoa Document Based Architecture, it's as simple as asking the shared NSDocumentController to actually do the work:
@implementation DrawAppDelegate(Scripting_Additions)
- (BOOL)application:(NSApplication *)sender openFile:(NSString *)filename {
 id doc = [[NSDocumentController sharedDocumentController]
openDocumentWithContentsOfFile:filename display:YES];
 return (doc != nil) ? YES: NO;
}
@end
Teach Your Users Well
Having your application be scriptable is one thing, teaching your users how to write scripts is another. So lets add a feature to Sketch which I originally implemented for Stone Create: the ability to save any document as an AppleScript that can then be executed in ScriptEditor to reproduce that document on the fly via scripting! This is useful for creating complicated templates which get modified slightly to produce current content.
The Object Model has many benefits, including code reduction, reusability, readability, modularity, data hiding, and data independence. So we'll take an OO approach to the design of our Script writer, with this simple algorithm to output the script:
 make a new document
 for each graphic do
 ask the graphic to make a new graphic just like itself
By creating a mutable string, each graphic will be asked in turn to supply the Apple Script needed to recreate it. Then, since an NSString knows how to save itself to disk, we're basically done.
Graphic will do most of the work, but will allow overrides and hooks for subclasses to set their special attributes. additionalProperties lets you specify any attributes to set during creation, such as the file name of an image, or whether a line goes up or down. setExtraPropertiesIntoStringBeforeTell and setExtraPropertiesIntoString lets you set attributes of the object after its creation, such as setting font and color attributes of a text object.
I've modified Image to "remember" its source file by adding an instance variable _sourceFileName, and modifying imageFile to return this, as well as GraphicView to set the image file name when you drag one in. Caveat: if you "paste" in a graphic, it won't have a filename, and thus won't be able to reproduce itself via a script.
Step 1: Add a new menu item to the main Menu:
 a. open Draw2.nib in InterfaceBuilder
 b. Drag a menu item from the Palette to the File menu
 c. title it "Save As AppleScript...", command-key: <OPTION><A>
 d. Double-click the First Responder in the "Instances" pane of the Draw2.nib window
 e. Double-click the "Actions" icon to drop down the actions
 f. Type <RETURN> to add a new action
 g. Retitle "myAction:" to "saveAsAppleScriptAction:"
 h. Control drag between the new menu item and the First Responder icon
 i. Double-click "saveAsAppleScriptAction:" in NSMenuItem target inspector
 j. Save the nib.
Step 2:
We'll continue adding code to Scripting_Additions.m, starting with the top level method saveAsAppleScriptAction:. Since each document needs to know how to do this, the method will be implemented in a DrawDocument category. The method will provide a SavePanel to allow the user to specify the script name, start the object graph writing the script, save the script, and then message the Finder to open the newly saved script for testing in Script Editor on OS X and in Edit on OS X Server (where you can copy/paste it into BlueBox's ScriptEditor). Because we want our Cocoa applications to be fully localizable, we'll use the NSLocalizedStringFromTable() macro so that localizers can modify the code to work without changing any source code.
Moreover, since we want the code to work on X Server as well as X, we'll use #ifdef SERVER where special code is needed for OS X Server. For example, X Server uses newlines '\n' to delineate lines, but Mac OS X and ScriptEditor use a carriage return, '\r'.
Since there are some bugs in Cocoa scripting in Developer Preview 3, we'll have another test for #ifdef DP3. To compile on OS X Server, add "-DSERVER" into the Compiler Flags field in the Project Inspector's Build Attributes window. Add "-DDP3" if you are compiling on Developer Preview 3.
Finally, for a Carbon application, such as ScriptEditor, to recognize and open a script file, we need to set the TYPE and CREATOR of the file. That will be accomplished with the help of some code I got from Ken Case of _URL_ with a friendly NSString interface I added.
The Code
// Scripting_Additions.h
#import <AppKit/AppKit.h>
#import <Scripting/Scripting.h>
#import "DrawAppDelegate.h"
#import "_URL_.h"
#import "_URL_.h"
#import "_URL_.h"
#import "_URL_.h"
#import "_URL_.h"
#import "_URL_.h"
@interface NSApplication(Scripting_Additions)
- (id)handleOpenFileCommand:(NSScriptCommand *)command;
@end
@interface DrawAppDelegate(Scripting_Additions)
// this is a good method to add
// it allows Sketch to open documents via the services interface:
- (BOOL)application:(NSApplication *)sender openFile:(NSString *)filename;
@end
@interface DrawDocument(Scripting_Additions)
// the method you hook up the menu item to the First Responder in Draw2.nib:
- (IBAction)saveAsAppleScriptAction:(id)sender;
// the actual method which generates the AppleScript:
- (NSString *)appleScript;
// TYPE/CREATOR:
- (int)setTypeString:(NSString *)type andCreatorString:(NSString *)creator
forPath:(NSString *)path;
@end
@interface Graphic(Scripting_Additions)
// each graphic knows it's own apple script:
- (void)appleScriptIntoString:(NSMutableString *)s;
// EACH GRAPHIC MUST OVERRIDE THIS WITH ITS ClassName from Terminology

Determining soil nitrogen content in working forestscharles.dillon2
Trees need nitrogen to grow. If soil nitrogen levels are low, then growth is limited. The ability to accurately monitor the amount of soil nitrogen in a working forest is helpful for predicting future growth and for knowing when to take corrective action (fertilizer, altered management practices) when soil nitrogen levels decline.

"Synthesized Poetry" on the musical composition "Poème Électronique" by Edgar Varèse
Title: Synthesized Poetry
Edgar Varèse's musical composition "Poème Électronique" is the first musical piece that was composed solely with synthesized sounds. This piece caused quite a disturbance upon its debut in 1948 at a multimedia exhibition in conjunction with the debut of the Phillips Pavilion The audience either disliked the piece with a passion or stood in awe of its magnificence. After a half century of constant criticism and praise, this piece is now accepted as a masterpiece (Hoffer 289). One must ask what makes it aesthetically valuable. The music sounds like a random arrangement of sounds on the first listen. Few find it pleasant to the ears. The mood of the music is eerie and cold. It breaks away from the traditional notion of music, as it lacks the presence of beat, melody, harmony, and meter (Hoffer 289). It is, however, a brilliant piece of music. "Poème Électronique" fully reflects culture of its time. It also brought a wave of musical evolution and is still highly influential today.
The decades that followed World War II could be described as a continuous explosion of new ideas in the field of science. The rate of new discoveries and inventions accelerated exponentially following World War II. The new technology enabled artists to create a new variety of sounds through the new instruments invented during this period. Edgar Varèse had a vision. He set out on a journey to create a complete new sound of music as early as the 1930's (Schaefer 3). He failed miserably in the earlier part of his career as a composer because he lacked the necessary technology to create revolutionary sounds, and he was simply too ahead of his time to be welcomed by any critics or the public. He was the forgotten man for decades (Ewen 851). At the age of 75 the sonic technology and the audience finally caught up to the vision of Edgar Varèse with the invention and advancement of synthesizers, computers, and tape recorders (Ewen 851). He was invited to compose...

, insert dummy data, and upgrade that.
If you are upgrading a pre-PostgreSQL 9.2 cluster that uses a configuration-file-only directory, you must pass the real data directory location to pg_upgrade, and pass the configuration directory location to the server, e.g., -d /real-data-directory -o '-D /configuration-directory'.
If using a pre-9.1 old server that is using a non-default Unix-domain socket directory or a default that differs from the default of the new cluster, set PGHOST to point to the old server's socket location. (This is not relevant on Windows.)
If you want to use link mode and you do not want your old cluster to be modified when the new cluster is started, make a copy of the old cluster and upgrade that in link mode. To make a valid copy of the old cluster, use rsync to create a dirty copy of the old cluster while the server is running, then shut down the old server and run rsync --checksum again to update the copy with any changes to make it consistent. (--checksum is necessary because rsync only has file modification-time granularity of one second.) You might want to exclude some files, e.g., postmaster.pid, as documented in Section 24.3.3. If your file system supports file system snapshots or copy-on-write file copies, you can use that to make a backup of the old cluster and tablespaces, though the snapshot and copies must be created simultaneously or while the database server is down.

SOURCES VERSUS CALLERS: A fundamental distinction is drawn between the sources of robocalls (the organizations or agents that initiate robocalls, e.g. charity organizations) versus the robocallers themselves (sets of phone lines called calling groups from which robocalls originate, including those of professional robocalling services). Requiring via federal legislation that both types of entities register themselves independently enables regulated robocalling, wherein legal robocalls are scheduled. Each of the entities has legal liability for its own function: a source must provide legal messages and a calling group is restrained to sending scheduled messages.
FACILITATOR: The executer of this solution (called the facilitator), could be the phone company, the government, or an outside group. The facilitator oversees registration and scheduling, and handles scheduled and unscheduled calls differently, as explained below.
SCHEDULED CALLS: A scheduled robocall must be dialed with a standard robocalling prefix, followed by an authorization code and the destination number. The facilitator selects a random sample of outgoing calls and compares them to the initial message provided by the source, to ensure that the proper initial outgoing message is being sent. A calling group caught substituting messages is frozen, meaning every number that participated in making the calls loses outgoing calling privileges. If customer complaints are received about the message, then the source is audited and possibly frozen.
UNSCHEDULED CALLS: Any phone line caught making illegal robocalls is immediately frozen. Registration of customer complaints about illegal robocalls is automated. The facilitator uses formulas to determine whether the number of complaints about a phone number merit investigation. We propose that these formulas take advantage of identifiable robocalling profiles based upon calling history. The next call from a phone number designated for testing is forwarded to a testing line to determine whether a live agent is calling. We suggest using a live agent, at least in the first phase. An automated alternative is a recorded question which would be answered easily by a human but not by a machine, using voice recognition to detect the response.

Couple is a system of forces whose magnitude of the resultant is zero and yet has a moment sum. Geometrically, couple is composed of two equal forces that are parallel to each other and acting in opposite direction. The magnitude of the couple is given by
Where are the two forces and is the moment arm, or the perpendicular distance between the forces.
Couple is independent of the moment center, thus, the effect is unchanged in the following conditions.
- The couple is rotated through any angle in its plane.
- The couple is shifted to any other position in its plane.
- The couple is shifted to a parallel plane.
In a case where a system is composed entirely of couples in the same plane or parallel planes, the resultant is a couple whose magnitude is the algebraic sum of the original couples.

 Salt State Files
 The SaltStack Platform is made up of two primary components: A remote execution engine which handles bi-directional communication for any node within your infrastructure (master and minions), and a configuration management system which maintains all infrastructure nodes in a defined state. Salt's configuration management system is known as the Salt State system. A Salt state is declared within a Salt State file (SLS) using YAML syntax and represents the information Salt needs to configure minions. A Salt Formula is a collection of related SLS files that will achieve a common configuration.
 SaltStack's GitHub page contains Salt formulas for commonly needed configurations, like creating and managing SSL/TLS certificates, installing and configuring the Apache HTTP Server, installing and configuring a WordPress site and many other useful formulas. You can easily add any of these pre-written formulas to your own Salt state tree using GitHub.
 This guide will use GitHub to fork and modify SaltStack's timezone formula and then use the formula on a Salt master to configure the time zone on two minions.
 Before You Begin
 1. If you are new to SaltStack, read A Beginner's Guide to Salt to familiarize yourself with basic Salt concepts.
 2. Download Git on your local computer by following our How to Install Git on Linux, Mac or Windows guide.
 3. Familiarize yourself with Git using our Getting Started with Git guide.
 4. Make sure you have configured git on your local computer.
 5. Use the Getting Started with Salt – Basic Installation and Setup guide to set up a Salt Master and two Salt minions: one running Ubuntu 18.04 and the second running CentOS 7.
 6. Complete the sections of our Securing Your Server to create a standard user account, harden SSH access and remove unnecessary network services.
 Note
 The steps in this guide require root privileges. Be sure to run the steps below with the sudo prefix. For more information on privileges, see our Users and Groups guide.
 Overview of the SaltStack Time Zone Formula
 In this section, we will take a closer look at SaltStack's timezone-formula, which can be used to configure a minion's time zone. A high-level overview of all the formula's state files and Jinja templates will be provided. Salt best practices recommends that formulas should separate the data that a state needs from the state itself to increase the flexibility and reusability of state files. We will observe how this is achieved in the time zone formula.
 1. In your browser, navigate to the timezone-formula on SaltStack's GitHub page. The README file is displayed and contains basic information about the formula. It notes the following details:
 - The purpose of the formula: to configure the time zone.
 - The available states: timezone
 - The provided default values: timezone: 'Europe/Berlin' utc: True
 The repository's FORMULA file includes additional details, including the supported OS families (Debian, RedHat, SUSE, Arch, FreeBSD), a summary, description and release number.
 2. Viewing the timezone-formula, click on the timezone directory to view its contents. You should see the following files:

 3. Take a look at the contents of the init.sls file that defines the timezone state:

 # This state configures the timezone.

 {%- set timezone = salt['pillar.get']('timezone:name', 'Europe/Berlin') %}
 {%- set utc = salt['pillar.get']('timezone:utc', True) %}
 {% from "timezone/map.jinja" import confmap with context %}

 timezone_setting:
 timezone.system:
 - name: {{ timezone }}
 - utc: {{ utc }}

 timezone_packages:
 pkg.installed:
 - name: {{ confmap.pkgname }}

 timezone_symlink:
 file.symlink:
 - name: {{ confmap.path_localtime }}
 - target: {{ confmap.path_zoneinfo }}{{ timezone }}
 - force: true
 - require:
 - pkg: {{ confmap.pkgname }}

 Salt will interpret the name of this file as timezone, since any init.sls file in a subdirectory is referred to by the path of the directory.
 This state file contains three state declarations, timezone_setting, timezone_packages and timezone_symlink. Below is a description of the configuration each declaration will accomplish on a Salt minion.
 - timezone.system: This state uses Salt's timezone state module to manage the timezone for the minion. The values for name and utc are derived from the corresponding Salt master's Pillar file. This is accomplished in the two variable assignment at the top of the file: {%- set timezone = salt['pillar.get']('timezone:name', 'Europe/Berlin') %} and {%- set utc = salt['pillar.get']('timezone:utc', True) %}.
 - timezone_packages: This state ensures that the package needed to configure time zones is installed on the minion. This value is derived from the confmap variable that is imported from the map.jinja file. The import is declared at the top of the file with the {% from "timezone/map.jinja" import confmap with context %} import statement. Later in this section, you will inspect the map.jinja file.
 - timezone_symlink: This state creates a symbolic link from the path defined in name to the location defined in target. This state will only execute if the timezone_packages state is executed successfully. This requirement is denoted by the require statement.
 4. Next, inspect the map.jinja file:
 timezone/map.jinja

 {% import_yaml "timezone/defaults.yaml" as defaults %}
 {% import_yaml "timezone/osfamilymap.yaml" as osfamilymap %}

 {% set osfam = salt['grains.filter_by'](
 osfamilymap,
 grain='os_family'
 ) or {} %}

 {% do salt['defaults.merge'](defaults, osfam) %}

 {%- set confmap = salt['pillar.get'](
 'timezone:lookup',
 default=defaults,
 merge=True,
 ) %}

 The map.jinja file allows the formula to abstract static defaults into a dictionary that contains platform specific data. The two main dictionaries are defined in the repository's timezone/defaults.yaml and timezone/osfamilymap.yaml files. The defaults.yml file serves as a base dictionary containing values shared by all OSes, while the osfamilymap.yml file stores any values that are different from the base values. Any file throughout the formula could make use of these dictionary values by importing the map.jinja file. In addition, any dictionary values can be overridden in a Pillar file. Overidding dictionary values will be discussed in the Modify Your SaltStack Formula section.
 5. Open the timezone/defaults.yaml file and the timezone/osfamilymap,yaml file to view the data stored in those files:
 timezone/defaults.yaml

 path_localtime: /etc/localtime
 path_zoneinfo: /usr/share/zoneinfo/
 pkgname: tzdata

 Suse:
 pkgname: timezone
 FreeBSD:
 pkgname: zoneinfo
 Gentoo:
 pkgname: sys-libs/timezone-data

 The values defined in these YAML files are used in the init.sls file.
 6. Open the pillar.example file to review its contents:
 pillar.example
 1
 2
 3
 4

 timezone:
 name: 'Europe/Berlin'
 utc: True

 This file provides an example for you to use when creating your own Pillar file on the Salt master. The init.sls file uses the values for name and utc in its timezone_setting state declaration. The value for name will set the time zone for your minion. The boolean value for utc determines whether or not to set the minion's hardware clock to UTC.
 Refer to tz database time zones to view a list of all available time zones. Since Pillar files contain sensitive data, you should not version control this file. In the Create the Pillar section, you will create a Pillar file directly on your Salt master.

This post explains how to test if a value is numeric. It is strange to me that there is not a built in method for this. And if there is, I would rather use it!
is-numeric
If you just want to use a module, use is-numeric that I wrote as part of this effort.
pip install is-numeric
Really simple. A method to test if a value is_numeric.
from is_numeric import is_numeric
print( is_numeric(1) ) # True
print( is_numeric(-1) ) # True
print( is_numeric(123) ) # True
print( is_numeric(123.456) ) # True
print( is_numeric("123.456") ) # True
print( is_numeric("x") ) # False
print( is_numeric("1x") ) # False
The rest of this post will explain different approaches.
Notes on the algorithm
I tested 4 algorithms:
 - str.isinstance
 - error-driven
 - regex
 - regex (plus str.isinstance)
str.isinstance
Using the built in .isinstance is limited in functionality, as it only looks for all characters being a digit, and fails on '-1' or '1.2'. Thus discard this approach.
def _str_isnumeric(value):
 if isinstance(value, (int, float)):
 return True
 if isinstance(value, str) and value.isnumeric():
 return True
 return False
error-driven
This is ugly in that it relies on errors in flow control. I hate it. It is like nails on chalk board to me. (spoiler alert: it is the most efficient of the test approaches)
def _is_numeric_using_error(value):
 try:
 float(value)
 return True
 except ValueError:
 return False
regex
This seems elegant. Check for a pattern.
def _is_numeric_regex(value):
 if isinstance(value, (int, float)):
 return True
 if isinstance(value, str):
 return bool(re.match(r"^-?\d+(\.\d+)?$", value))
 return False
regex (plus str.isinstance)
The regex solution, with a small change to check if all numeric digits prior to doing regex.
def _is_numeric_regex_plus_isnumeric(value):
 if isinstance(value, (int, float)):
 return True
 if isinstance(value, str) and value.isnumeric():
 return True
 if isinstance(value, str):
 return bool(re.match(r"^-?\d+(\.\d+)?$", value))
 return False
Performance Comparison
I ran a very non-scientific test.
Approach
Create a list of inputs, with a mix of float/int, strings that represent numeric values, and non-numeric values. Iterate x time over the list for a given algorithm. Repeat for each algorithm.
Variable
 - % of inputs that are non-numeric (theory is that error-driven will perform better when the value is numeric, and less efficient when the value cannot be cast to float and an error is raised)
Findings
When most values are numeric 1 (0-50%), the error-driven approach outperforms other approaches (up to 3x).
When most values are non-numeric 2 (80%), the regex (plus str.isinstance) approach has a very slight advantage (4%).
Conclusion
without knowning the % of non-numeric values, it is recommended to use the error-driven approach. As such, the error-drive approach is exposed through the is_numeric function in this package.

How to Force Safari to Sync with iCloud
When iCloud syncing is turned on, Safari is supposed to automatically sync your web browsing history and tabs with your other iCloud-enabled OS X and iOS devices. That doesn't always work as described, however. If your Safari history and settings on the Mac aren't syncing over to iCloud, you can manually force the sync process.
This setting in the Mac app will make sure recently visited webpages will also be accessible from your iPad or iPhone. First we'll have to enable the hidden Debug menu in Safari.
1. Quit Safari in OS X. Use the Command+Q shortcut to quickly close the program or go to Safari > Quit Safari.
2. Open Terminal. You can do this with the Command+Spacebar shortcut and searching for "terminal" or going to your Applications > Utilities folder.
3. Type in the command below:
defaults write IncludeInternalDebugMenu 1
4. Press Enter.
5. Relaunch Safari. You should see the new debug menu in Safari.
6. Click Debug > Sync iCloud History.
This will manually force a sync of your Safari history to your other Apple devices over iCloud.

Plants are essential to everyone's lives.
'Plants capture energy from the sun and all life on land, directly or indirectly, depends on them. So, ultimately, plants fuel the diversity of life on earth'
Sir David Attenborough
Plantlife seeks to conserve wild plants and fungi using a range of approaches. We work to conserve key habitats and we have designated Important Plant Areas to draw attention to those parts of the country that sustain important collections of plants. We also devise and carry out projects aimed at recovering declining populations of key species and demonstrating how they can be effectively conserved in the future.
We also promote wild plants and fungi in culture, for instance through County Flowers and the Grow Wild campaign.

Why do I see a form submit with no associated site visit on a timeline?
1) Cookie shared by two users
ActiveDEMAND tracks prospects in many ways. One way is using cookies. If someone loads a page, the tracking script stores a cookie on the visitor's computer via the browser. The base case today is that people do not share computers without logging out of the browser. More people are concerned about someone accessing their personal device than they are about having a cookie stored in their browser. Thus the tracking is quite good. Where it falls down is if someone shares their computer with someone else. Or if one person is filling out forms for multiple people. ActiveDEMAND will only allow one contact to own the session (sessions are not shared). Thus if someone fills out the same form for two different contacts, only one of the two contacts will 'own the session', the other will show a form submit with no web session.
2) Employee Suppression via 'owned IP addresses'
As more ActiveDEMAND users are marketers, clearly the marketer will do a lot of testing on assets. As ActiveDEMAND is very good at tracking, this poses a problem. Marketers testing will impact the marketing stats. Thus a user of ActiveDEMAND can choose to associate their IP address with the work they are doing. If a marketer clicks BLOCK MY IP on their user profile, ActiveDEMAND will assume all visits from that IP are the employee, thus it will suppress visit data etc from that employee to keep the ActiveDEMAND stats clean
How do I find the 'lost visit'?
Often the form submit will have an IP address on the timeline. You can search the drill down reports for this IP address. Another place to look is the employer of the contact that filled out the form. Are there other form submits by that company from that IP? Another trick is to look at the contact's Map. The form submit will show up on the map. Use the dashboard map, isolate the time range, search for other website visits or form submits on the map. Chances are high that one of those owns the session.

RIYADH: With the whole world experiencing a swift digital transformation amid the coronavirus disease (COVID-19) pandemic, Saudi Arabia, as the G20 host, shoulders the responsibility to help the world move forward by swiftly adopting new health protocols and setting an example, said Indonesian Ambassador to Saudi Arabia Agus Maftuh Abegebriel.
In an interview with Arab News, Abegebriel said: "Saudi Arabia did not let the pandemic become an unfortunate moment. The G20 swiftly adopted new health protocols, and an online mechanism was prepared for the upcoming summit in November. The extraordinary summit in March ran well online — evidence of how well Saudi Arabia handled the G20's meetings during the pandemic. I hope that we can learn from the Saudi presidency for handling the G20 in 2023.
"The G20 was born out of crisis back in 1999, and was again challenged in 2008-2009 by the global financial crisis. That crisis came alongside the European sovereign debt crisis, and several eurozone members were unable to repay or refinance their government debt. World GDP growth had fallen from 4.3 percent in 2007 to 1.8 percent in 2008, and then continued to minus 1.6 percent in 2009.
"The G20 has played an essential role in enabling international cooperation, and taken responsibility for global leadership in times of crisis. World GDP growth in 2010 successfully returned to 4.3 percent, with an average level of 2-3 percent in the next several years," he added.
"Now, COVID-19 has had a more adverse impact on activity in 2020 than anticipated, and the recovery is projected to be slower than previously predicted," he said.
"It is important to collaborate to ensure universal and equitable access to vaccines. It is important to work together to safeguard the global economy and avoid global depression. It is important to send a strong message that global recovery after the pandemic must be aligned with the 2030 UN Sustainable Development Goals to create more inclusive and sustainable growth," he added.
Abegebriel continued that the G20 Summit in Riyadh would face major issues and high expectations, especially in areas devastated by COVID-19.
"G20 members face many common and pressing challenges, even more now with COVID-19. Consequently, the theme brought by Saudi Arabia, "Realizing opportunities of the 21st century for all," is … relevant with the situation today. This is the time when countries share their collective efforts and responsibilities to address those challenges together, to make sure no one is left behind," said the ambassador.
Abegebriel underscored that empowering people needed good decisions, and that the pandemic had reversed decades of progress on closing the gender gap in the labor market. It was important, he said, to put this issue in every aspect of new policy.
"We view that achieving women's empowerment is essential to achieve sustainable and equitable development, which is in line with the Agenda 2030 framework," he said.
Furthermore, the environment and its preservation remains of major importance. "We support the initiative by the Saudi presidency to support existing efforts to prevent land degradation and habitat loss, as well as the initiative to accelerate scientific knowledge and technology development in support of coral reef survival, conservation, resilience, adaptation and restoration," he said.
On an urgent need for the G20 to take steps that lead to more employment and growth, the envoy said: "Absolutely, in the long run, the deep recessions triggered by this pandemic (are) most likely to leave an eternal scar across sectors and fields, such as the disruption of global trade, fragmentation of supply chains, lower investment and affect people-to-people connectivity."
Pressure on weak health care systems, loss of trade and tourism, declining remittances, subdued capital flows and tight financial conditions amid mounting debt will daunt many countries, he added. The pandemic has gravely impacted the labor market, especially for the most vulnerable: Low-paid workers, young people, women, under-represented groups, the self-employed and informal sector workers.
"Strengthening social protection systems is vital to prevent a more severe situation that could occur during the crisis period," he said.
"There are reasons why the G20 Summit hosted by Saudi Arabia is historic. First, the summit is being held amid the deepest global recession in decades. Second, this summit is the first in the history of G20 convened online. As Saudi Arabia is the only country in the Middle East to be a member country of the G20, it is important to represent and show Saudi leadership in the region. We congratulate the Kingdom for its able leadership and its utmost effort in leading this forum to ensure the relevance of the G20 during the crisis," Abegebriel said.
"Indonesia, which has a predominantly Muslim population, has a strong relationship with Saudi Arabia. The state visits by President Joko Widodo in 2015, 2018 and 2019 mark the importance of Saudi Arabia for the people of Indonesia. The historic visit by King Salman to Indonesia in 2017 showed the remarkable cooperation between the two countries," he added. "I hope cooperation between Saudi Arabia and Indonesia will strengthen.
"Saudi Arabia has prepared the G20 Summit very well. Indonesia is keen to learn from Riyadh, to prepare ourselves for hosting the G20 Summit in 2023."
