we needed to work with the last query made, we could pass false as a parameter to the method and JDatabaseDriver would return the last JDatabaseQuery object to us. For most practical purposes, we will always want a new empty query object and will pass true to this method. JDatabaseQuery object has lots of methods that help you create queries for accessing the database. These are probably best understood by example.
In our module, we want to get some random quote from the database. Well the first thing we need to figure out is how many quotes are there to work with. Fortunately, this is a simple query, all we have to do is select the count function on the table. The SQL code for this would look like this.
SELECT COUNT(*) FROM <tablename>;
Here <tablename> represents the table we want to do the count on. Creating the SQL with the JDatabaseQuery object is pretty simple and would use code like the following.
$query->select("COUNT(*)");
$query->from("#__mod_random_quote");
JDatabaseQuery allows us to build our queries in pieces and it takes the responsibility of assembling them together for us. The select() method aboves takes as a parameter the column names or SQL function (like count()) that we would use in a normal SQL SELECT statement. In this case we pass along the COUNT(*) function to it. Finally, the from() method takes as a parameter anything you would pass long in a regular SQL FROM statement. In this case, we are passing the database table of our module. Note that we have prefixed the table name with the #__ characters that Joomla will use to derive the database table prefix.
It should also be noted that these methods can be chained together. For example, the two lines of code above could be written as follows so feel free to pick your poison.
$query→select("COUNT(*)")->from("#__mod_random_quote");
With the JDatabaseQuery complete, we only need to pass this back to the JDatabaseDriver object like so.
$db->setQuery($query);
The setQuery() method will take the query that we created and store it in the database driver object. All that is left to do is have the driver execute and return the results to us.
There are a number of methods available to return the data from the database, and which one you use depends on the format of data you need returned back. Let me explain a little further. The methods available allow you to return a single result, a single row, multiple rows, a single column, data as an array, an associative array and as an object. The end result is that you have a lot of latitude with JDatabaseDriver. In our example we need only a single result, the number of rows in the table. We can do that with the following code.
$count = $db->loadResult();
The loadResult() method will return a single value from the database. In our case we executed the COUNT(*) function which returns the number of rows in the table which we expect only a single value. Once the value has been returned with loadResult() we assign it to the $count variable so that we can use it later.
To summarize, getting data from the database is pretty straight forward and for the most part we will always follow these same steps.
 1. Get the database driver from JFactory
 2. Get a Query object from the database driver
 3. Set up our query using the methods available from the JDatabaseQuery class
 4. Store the Query back into JDatabaseDriver
 5. Execute the query using the method that make sense for the data we expect to receive.
If you want to get a head start on using the database with Joomla, take the time to read the documentation which can be found at _URL_
Now that we know how many rows are in the table, we can use this to select one randomly by using some php code like the following.
$recordNumber = rand(1, $count);
The above line of code will generate a random number between 1 and the number of rows we have in the table. In my database example from the last tutorial, this will be 50. Once we have this number then we can use it to select the specific record from the table. NOTE: The rand() function I am using above is a pseudo random number generator and does not generate cryptographically secure values, and should not be used for cryptographic purposes. Additionally, we assume that all the index, id values in the table are in sequential order with none missing. Since we ultimately have control over the data being stored in the database, we should experience no problems. But if, for example, we deleted a row from the table leaving that index empty, it is possible that the deleted index id would be randomized and then it not be in the database resulting in an error.
Now that we have the record number we want from the table, we can get a new Query object and create the query with the following code.
$query = $db->getQuery(true);
$query->select("name, quote, source");
$query->from("#__mod_random_quote");
$query->where("id={$recordNumber}");
The above code will generate the following SQL Query.
SELECT name, quote, source FROM #__mod_random_quote WHERE id=#
Keep in mind the following about the above query. Joomla will use your correct prefix for the table name above and the # I used after the id= is actually the random number we generated and assigned to $recordNumber.
With the Query out of the way, we expect only one row from the database to match our Query criteria, so we would want to use one of the methods from the JDatabaseDriver that returns a single row. We have a few to choose from. We can use loadRow(), loadAssoc() or loadObject(). Let me explain each briefly.
loadRow() will return one row from the database as an indexed array with the first column being at index zero. So a row would be accessed like the following:
$record[0]; //contains the name column value
$record[1]; // contains the quote column value
$record[2]; // contains the source column value
loadAssoc() is similar to loadRow() but it return the row as an associative array where each key is the column name. The row would be accessed like the following:
$record['name']; //contains the name column value
$record['quote']; // contains the quote column value
$record['source']; // contains the source column value
Finally, loadObject() returns the row as a standard PHP object where each column will be accessed with the arrow operator. You can access the data like the following:
$record->name; //contains the name column value
$record->quote; //contains the quote column value
$record->source; //contains the source column value
Which method you choose really depend on how you plan to access the data in code. I will leave that as an exercise for you. Continuing with this example, I will use the loadObject() method. So to complete our code examples from above, we have the query finished and we need to submit the query to the JdatabaseDriver object and then execute the loadObject() method to retrieve the data. That can be accomplished with the following code.
$db->setQuery($query);
$record = $db->loadObject();
After executing the above code, the random quote will be loaded from the database and stored in the $record variable. Now let's put it all together. Open the helper.php file and add the following lines marked in red.
<?php
/**
* Helper class for mod_random_quote module.
*/
abstract class ModRandomQuoteHelper {
public static function getRandomQuote() {
// database code goes here.
// Get the JDatabaseDriver object from JFactory
$db = JFactory::getDbo();
// Get the JDatabaseQuery object from the JDatabaseDriver object
$query = $db->getQuery(true);
// Build the query
$query->select("COUNT(*)");
$query->from("#__mod_random_quote");
// Save the query to the JDatabaseDriver object
$db->setQuery($query);
// Save the record count to a variable
$count = $db->loadResult();
// Randomize the record that we want
$recordNumber = rand(1, $count);
// Build the query for the record we want
$query = $db->getQuery(true);
$query->select("name, quote, source");
$query->from("#__mod_random_quote");

New mothers and babies could be at risk of contracting Legionnaires' disease from some pre-heated birthing pools, the government has warned.
Birthing pools filled in advance of the expected date of delivery are dangerous and are to be avoided, the warning from Public Health England states.
In 2014, a new born baby in England was found to have contracted Legionnaires' disease following a home birth in a pre-heated birthing pool.
Legionnaires' is a serious and sometimes fatal lung infection caused by inhaling the Legionella bacteria when suspended in water droplets.
Expectant mothers are advised to discuss matters with their midwife
Symptoms can materialise as rapidly as after two days after exposure and are usually flu-like, such as coughing, shortness of breath and chest pains.
Legionella bacteria grow in stagnant water between 20C and 45C, especially where nutrient rich rust, sludge, scale, sediment and algae are present.
If the water temperature of a birthing pool has been maintained for an extended time before birth by the use of a heater and circulation pump, this allows for conditions where Legionalla bacteria can grow.
Traditional birthing pools are filled with water once the pregnant woman goes into labour are considered to be safe. These come with disposable liners and the water is not kept warm using a heater.
One of the new birthing pools at East Surrey Hospital
Fixed birthing pools in NHS units are also considered safe as they are subject to stringent infection control procedures which prevent Legionella growing in the water and system.
Pregnant women are advised to discuss with their midwives if they are planning to use a birthing pool at home and have any concerns.
Midwives will be able to talk through the birth plan and give advice on how best to keep both mother and baby safe.


The Science of Bubble Rings
Great video of cooped up dolphins blowing underwater bubble rings to pass the time. Before we get all out of sorts that this is some sort of compulsive, depressive behavior from being locked up, note that this been observed in the wild as well.
I just can't help but look at that and wish that I still smoked cigarettes. I used to be an epic ring blower. Andrew and I actually knew a kid named Michael Northrope who could blow smoke squares. It was awesome! No joke! We were like 13 and he was 16. But I digress...

One bubble ring to bind them...
Researchers posting on Deep Ocean explain the physics of bubble rings, including a how-to description of making them yourself. It turns out that dolphins bubble rings are vortex rings just like smoke rings but are created in different ways:
(From Deep Ocean) Dolphins create bubble rings by blowing air in a water vortex ring: by flipping a fin they create a vortex ring of water. The then blow air in the ring, which goes to the center of the vortex ring. In the water vortex ring the natural location of the air is in the center of the vortex. When air and water move in a circular path like they do in the vortex ring, air and water are separated due to the centripetal force. Since density of water is larger than air, water moves at the outside, while the air ends up in the middle.

Something tells me these researchers didn't spend their teenage afternoons smoking in the woods behind Earl's house, blowing smoke squares to impress younger kids, but apparently they shared the same fascination... although now they work in a university laboratory and Michael Northrope is doing 5-10 years for aggravated assault in upstate Connecticut...just a hunch.

In the same region and time, the highest fish abundance is observed. Mostly young individuals of gobies, small sandeel, flounder, three-spine stickleback and young herring occur. In this work we compare how toxic blooms of cyanobacteria influence the number and structure of fish communities in a coastal zone. The results obtained in our study were rather unexpected. More fish species were caught and the biomass of fish was higher during a bloom than in a month following the sampling (no bloom).

Felfe, Christina. (2006) Objective Trends and Perceptions of Health Status in Germany. ENEPRI Research Reports No. 21, 22 August 2006. UNSPECIFIED.
This paper identifies previous trends and future prospects surrounding the health status of the population and the utilisation of health care services, based on data from the German Socio-Economic Panel (_PHONE_). Health status and the demand for health care services is examined in conjunction with the following variables: health satisfaction; the degree to which health status hinders the fulfilment of daily life activities; disability and chronic illnesses; and the probability, frequency and duration of hospital stays. The first part of the paper describes the main trends associated with these indicators. Then a further analysis is undertaken with regard to the determinants of health status. For this latter purpose, a sample of about 21,000 persons (aged 16 and older) has been used. The determinants are assessed against two measures of health status: a subjective measure, which is self-reported satisfaction with health, and an objective measure, which is the degree of being hindered by health in daily life activities. An interesting question explored alongside the findings is whether health care expenditures have increased because the overall health of the population has worsened or because expectations have risen.

Hydrate and PVT prediction software
What is HydraFLASH?
Why use HydraFLASH?
Comprehensive experimental facilities have allowed us to tune and validate the model using a vast, largely unpublished in-house hydrate and hydrocarbon equilibria database.
As a result, HydraFLASH is the most accurate model available for predictions involving real-world production systems.
Equation of State & Mixing Rules
A combination of equations of state (EoS) and appropriately selected mixing rules provide a powerful tool capable of modelling complicated multiphase, multicomponent systems. The SRK and PR EoS are commonly used for modelling in the oil and gas industry and are included in HydraFLASH in addition to the Peneloux density correction and different mixing rules.
HydraFLASH incorporates the Valderrama-Patel-Teja (VPT) EoS with non-density dependent mixing rules (NDD) used in modelling fluid phases. The combination has proved to be very effective for modelling systems with polar as well as non-polar components. The CPA (Cubic Plus Association) is a new approach that has a number of advantages when modelling fluid phase equilibria for systems containing components which can form hydrogen bonds (e.g. water, methanol, ethanol, MEG).
Hydrate Phase Modelling
The hydrate phase is modelled by the solid solution theory of Van der Waals and Platteeuw. The Kihara model for spherical molecules is applied in order to calculate the potential function for compounds forming the hydrate phases.
Electrolyte Solution Modelling
Electrolytes are modelled by an improved Aasberg-Petersen model. The model can be used over a wide range of temperature and salt concentrations, and is capable of handling mixed electrolyte solutions.
Continuously tested for real process scenarios with validation against in-house and literature experimental data.
The HydraFLASH hydrate model can accurately predict the formation of hydrates and the inhibition effect and distribution of hydrate inhibitors in oil and gas systems. If the water contains salts, the influence of these salts on the hydrate formation conditions will also be taken into account.
HydraFLASH can accurately predict:
- The most stable type of hydrate formation structure ( I, II and H)
- If hydrates will form at a given temperature and pressure
- The minimum inhibitor injection rate to prevent hydrates as a function of the water cut
- The distribution of inhibitor in different phases
- Maximum water content permissible before hydrate formation
- The hydrate formation and inhibition effect of ethanol and i-propanol, n-propanol
New offers are available for a limited time.
There are currently a variety of options available for purchasing HydraFLASH so if you require a quotation or have any other questions simply get in touch with us.
If you are interested in a one month free trial of HydraFLASH then get in touch with us.

Horse (Equus ferus caballus)
The Kerry Bog Pony is a mountain and moorland breed of pony that originated in Ireland. Possibly descended from the Irish Hobby horse, it originally lived a mainly feral existence in the peat bogs of what is now County Kerry in southwestern Ireland. Local inhabitants used the ponies as pack and cart horses for transporting peat and kelp to the villages. The breed developed physical characteristics including a low weight-to-height ratio and an unusual footfall pattern, which helped it move on soft ground such as peat bogs. The ponies were known for hardiness and an ability to survive in harsh conditions.
War, increasing mechanisation and declines in the local small-farm population almost resulted in the breed's extinction. In 1994, a local man found and genetically tested a herd of 20 ponies he used as the foundation stock for rebuilding of the breed. In the early 2000s, the breed was recognised by the Irish Department of Agriculture and Food and the European Commission; equine passports began to be issued for members of the breed, and small numbers of ponies were exported to the United States. At the same time, Irish and American breed registries were formed. As of 2011, the registered population is more than 300 ponies.
Kerry Bog Pony head
The head and thick mane and forelock of a Kerry Bog Pony
Kerry Bog Ponies generally stand 10 to 12 hands (40 to 48 inches, 102 to 122 cm) high. The Irish breed standard calls for mares to stand 10–11 hands and stallions and geldings to stand 11–12 hands. Their low weight-to-height ratio enables them to walk on wet ground. Their hind feet tend to track outside their front feet, allowing better progress on soft ground. They exhibit a relatively upright pastern and steep hoof angle compared to other breeds, possibly another characteristic that aids their movement in peat bogs. Kerry Bog Ponies are easy keepers, and when feral they lived on low-nutrient heather, sphagnum moss and possibly kelp from the shoreline. Overall, they are muscular and strong and their heads have concave profiles, small ears and large eyes. Their winter coat is long and dense, serving as protection from harsh weather. All solid coat colours are found, including dilute colours such as palomino, and white markings are common. Pinto-coloured animals are not accepted by the Irish registry. The breed is known by enthusiasts for strength, intelligence and athleticism, and generally used for driving, as companion animals and for therapeutic riding programs.
Kerry Bog Ponies were historically known in Ireland as "hobbies", possibly derived from the Gaelic practice of obaireacht, or the calling out of "Hup, Hup" to attract a pony back to the farmyard. It is considered one of the mountain and moorland pony breeds from Britain and Ireland. A 2006 study using mitochondrial DNA found that the Kerry Bog Pony is not closely related to the other two native Irish breeds, the Irish Draught and the Connemara pony. It has a rare haplogroup more closely related to other small horse breeds found in western Europe, including the Shetland pony and Icelandic horse. A 2012 study found relationships between the Kerry Bog Pony and the Dartmoor Pony and Exmoor Pony breeds, and a lack of common ancestry with the Welsh Pony, as well as reinforcing the lack of relationship to the Connemara. The study also suggested that the Kerry Bog Pony population had some amount of crossbreeding with other mountain and moorland breeds as part of the initial attempts to increase the population in the 1990s. The Kerry Bog Pony may have been one of several breeds that contributed to the development of the Gypsy Vanner horse (also known as the Irish Cob).

The original ancestry of the Kerry Bog Pony is unknown, but there were horses living a feral existence in peat bogs in what is now County Kerry in southwestern Ireland since at least the 1600s. Some enthusiasts claim that the breed is a descendant of the ancient Irish Hobby. In a 1617 book illustration, the horses pictured resemble both the Kerry Bog Pony of today and the original Irish Hobby, showing the two breeds' similar morphology. Originally, Kerry Bog Ponies were used to transport peat and kelp. They were known for their ability to navigate through the bogs, around soft spots and over rocks often in wet and windy weather, and for their strength relative to their small size. Some were trained to work in harness and used to pull carts. The ponies were turned loose into the peat bogs when they were not needed, then later re-caught for work. Few if any breeding programs existed; instead, they were left to reproduce in their feral setting. In 1720, Isaac Ware travelled to County Kerry and observed that the horses resembled Asturcón ponies from Spain.
The British cavalry became aware of the ponies in 1804, during the Peninsular War, and used them as pack animals during the conflict; most did not return to Ireland. The famine of 1845–1852 furthered their decline, as farmers who previously utilised them died or emigrated. In addition, Spanish donkeys were brought to the island to replace the ponies, and when peat declined as a fuel source, pack animals were no longer needed. In the 1850s, farms began to be consolidated, and more machinery and large draft horses were employed, further reducing the number of ponies needed. Consequently, the ponies were left to run feral, mostly ignored and sometimes shot at by locals.
Kerry Bog Village Museum Kerry Bog Pony
A pony at the Kerry Bog Village Museum
In 1994, John Mulvihill, who operated the Red Fox Inn at the Kerry Bog Village in Glenbeigh, County Kerry, began a search for remnants of the Kerry Bog Pony population, despite reports that the breed was extinct. He eventually found 20 ponies that resembled those he remembered from his childhood, and removed them from the bog to his stables. In 1995, he had blood typing performed on the ponies by Weatherby's Ireland, which identified their DNA markers. Subsequent DNA testing showed them to be a unique breed that formed a separate population from other local ponies and from other breeds in Ireland and Great Britain. Of these 20 ponies, only one was a stallion, named Flashy Fox. Between 1995 and 2012, he sired more than 140 foals, and played a significant role in repopulating the breed.
Mulvihill continued breeding and promoting the ponies, and in 2002, the breed was recognised by the Irish Government as the Irish Heritage Pony. The same year, the Kerry Bog Pony Society was formed. Also in 2002, Americans became interested in the breed, and the first ponies were exported from Ireland to the US in 2003, to a farm in Ohio. In 2005, the American Kerry Bog Pony Society was founded, with 11 initial registrants. Also in 2005, the Irish Department of Agriculture and Food and the European Commission recognised the Kerry Bog Pony as an official breed; the following year, the Irish Horse Board issued the first equine passports for members of the breed. Until 2009, there was an exception in place that allowed unrelated ponies that met the physical breed standards to be bred as Kerry Bog Ponies, with the offspring being registered and given passports certifying them as purebred Kerry Bog Ponies. This was in part due to a concern of inbreeding among the small number of ponies initially registered. Kerry Bog Ponies were also part of the Irish Rural Environment Protection Scheme (closed to new applicants in 2009), which financially rewarded farmers for using environmentally-friendly methods. The Kerry Bog Village, an open-air museum on the Ring of Kerry is one location that breeds and houses part of the existing Kerry Bog Pony population.
As of 2011, there were 335 mares and 51 stallions registered with the Irish registry, which included 59 new foals that year. Herd numbers have steadily increased since registrations began in 2005. These numbers make the Kerry Bog Pony third in population numbers among Irish breeds, behind the Connemara pony and the Irish Draught. Despite the increasing numbers, the breed is still considered to be critically endangered by the Equus Survival Trust. The horses are administered by the Kerry Bog Pony Co-Operative Society of Ireland (formerly the Kerry Bog Pony Society), which is based in Ireland with a branch in Great Britain. Inspections are required before ponies are allowed into the studbook. The book is divided into four classes: Class 1 ponies meet all requirements, Class 2 ponies do not meet the height requirement, Class 3 ponies do not meet the color requirements, and Class 4 ponies have yet to submit to an official inspection. The breed association has hosted an annual breed show and sale in Glenbeigh, County Kerry since 2007.

y^2/4} by a multiplicative factor of {4} at most), and disappears completely in the most extremal case {x=y}, which helps explain why one could get away with using this quantity in the proof here. But it would be significantly harder (though still not impossible) to use non-symmetric intermediaries to prove the sharp version
\displaystyle xy \leq \frac{x^2 + y^2}{2}
of (8) (that is to say, the arithmetic mean-geometric mean inequality). Try it!
Similarly, consider the task of proving the triangle inequality
\displaystyle |z+w| \leq |z| + |w| \ \ \ \ \ (9)
for complex numbers {z, w}. One could try to leverage the triangle inequality {|x+y| \leq |x| + |y|} for real numbers by using the crude estimate
\displaystyle |z+w| \leq |\hbox{Re}(z+w)| + |\hbox{Im}(z+w)|
and then use the real triangle inequality to obtain
\displaystyle |\hbox{Re}(z+w)| \leq |\hbox{Re}(z)| + |\hbox{Re}(w)|
and
\displaystyle |\hbox{Im}(z+w)| \leq |\hbox{Im}(z)| + |\hbox{Im}(w)|
and then finally use the inequalities
\displaystyle |\hbox{Re}(z)|, |\hbox{Im}(z)| \leq |z| \ \ \ \ \ (10)
and
\displaystyle |\hbox{Re}(w)|, |\hbox{Im}(w)| \leq |w| \ \ \ \ \ (11)
but when one puts this all together at the end of the day, one loses a factor of two:
\displaystyle |z+w| \leq 2(|z| + |w|).
One can "blame" this loss on the fact that while the original inequality (9) was invariant with respect to phase rotation {(z,w) \mapsto (e^{i\theta} z, e^{i\theta} w)}, the intermediate expressions we tried to use when proving it were not, leading to inefficient estimates. One can try to be smarter than this by using Pythagoras' theorem {|z|^2 = |\hbox{Re}(z)|^2 + |\hbox{Im}(z)|^2}; this reduces the loss from {2} to {\sqrt{2}} but does not eliminate it completely, which is to be expected as one is still using non-invariant estimates in the proof. But one can remove the loss completely by using amplification; see the previous blog post for details (we also give a reformulation of this amplification below).
Here is a slight variant of the above example. Suppose that you had just learned in class to prove the triangle inequality
\displaystyle (\sum_{n=1}^\infty |a_n+b_n|^2)^{1/2} \leq (\sum_{n=1}^\infty |a_n|^2)^{1/2} + (\sum_{n=1}^\infty |b_n|^2)^{1/2} \ \ \ \ \ (12)
for (say) real square-summable sequences {(a_n)_{n=1}^\infty}, {(b_n)_{n=1}^\infty}, and was tasked to conclude the corresponding inequality
\displaystyle (\sum_{n \in {\bf Z}} |a_n+b_n|^2)^{1/2} \leq (\sum_{n \in {\bf Z}} |a_n|^2)^{1/2} + (\sum_{n \in {\bf Z}} |b_n|^2)^{1/2} \ \ \ \ \ (13)
for doubly infinite square-summable sequences {(a_n)_{n \in {\bf Z}}, (b_n)_{n \in {\bf Z}}}. The quickest way to do this is of course to exploit a bijection between the natural numbers {1,2,\dots} and the integers, but let us say for sake of argument that one was unaware of such a bijection. One could then proceed instead by splitting the integers into the positive integers and the non-positive integers, and use (12) on each component separately; this is very similar to the strategy of proving (9) by splitting a complex number into real and imaginary parts, and will similarly lose a factor of {2} or {\sqrt{2}}. In this case, one can "blame" this loss on the abandonment of translation invariance: both sides of the inequality (13) are invariant with respect to shifting the sequences {(a_n)_{n \in {\bf Z}}}, {(b_n)_{n \in {\bf Z}}} by some shift {h} to arrive at {(a_{n-h})_{n \in {\bf Z}}, (b_{n-h})_{n \in {\bf Z}}}, but the intermediate quantities caused by splitting the integers into two subsets are not invariant. Another way of thinking about this is that the splitting of the integers gives a privileged role to the origin {n=0}, whereas the inequality (13) treats all values of {n} equally thanks to the translation invariance, and so using such a splitting is unnatural and not likely to lead to optimal estimates. On the other hand, one can deduce (13) from (12) by sending this symmetry to infinity; indeed, after applying a shift to (12) we see that
\displaystyle (\sum_{n=-N}^\infty |a_n+b_n|^2)^{1/2} \leq (\sum_{n=-N}^\infty |a_n|^2)^{1/2} + (\sum_{n=-N}^\infty |b_n|^2)^{1/2}
for any {N}, and on sending {N \rightarrow \infty} we obtain (13) (one could invoke the monotone convergence theorem here to justify the limit, though in this case it is simple enough that one can just use first principles).
Note that the principle of preserving symmetry only applies to direct approaches to proving inequalities such as (1). There is a complementary approach, discussed for instance in this previous post, which is to spend the symmetry to place the variable {f} "without loss of generality" in a "normal form", "convenient coordinate system", or a "good gauge". Abstractly: suppose that there is some subset {Y} of {X} with the property that every {f \in X} can be expressed in the form {f = Tg} for some {T \in G} and {g \in Y} (that is to say, {X = GY}). Then, if one wishes to prove an inequality (1) for all {f \in X}, and one knows that both sides {A(f), B(f)} of this inequality are {G}-invariant, then it suffices to check (1) just for those {f} in {Y}, as this together with the {G}-invariance will imply the same inequality (1) for all {f} in {GY=X}. By restricting to those {f} in {Y}, one has given up (or spent) the {G}-invariance, as the set {Y} will in typical not be preserved by the group action {G}. But by the same token, by eliminating the invariance, one also eliminates the prohibition on using non-invariant proof techniques, and one is now free to use a wider range of inequalities in order to try to establish (1). Of course, such inequalities should make crucial use of the restriction {f \in Y}, for if they did not, then the arguments would work in the more general setting {f \in X}, and then the previous principle would again kick in and warn us that the use of non-invariant inequalities would be inefficient. Thus one should "spend" the symmetry wisely to "buy" a restriction {f \in Y} that will be of maximal utility in calculations (for instance by setting as many annoying factors and terms in one's


text: Department of Water Resources' San Luis Field Division will inspect the existing septic tank and underground sewer line for the State Water Project's Romero Visitor Center. Waste from the septic tank will be pumped and taken offsite. A sewer pipe inspection robot with a camera will be inserted into the sewer line to trace its alignment. This will be done to determine if the sewer line location matches the original blueprint of the sewer line. While the alignment of the sewer line is being traced, the line will also be inspected for any potential breaks or leaks. If any breaks in the sewer line are detected, soil sampling will be conducted within an approximately 131,966-square foot work area. Soil samples will be collected using a protocol developed by the San Luis Field Division. A hand auger will be used to drill test holes along the sewer line. The test holes will range between 6 to 10 inches in diameter and will be up to 7 feet below ground. If the soil is too hard to use a hand auger, a backhoe will be used to dig test holes up to 30 inches long by 30 inches wide and 7 feet deep. Soil samples will be collected from all test holes. Once soil sampling is completed, all test holes will be backfilled and compacted to the original grade. The soil samples will be analyzed offsite. The State Water Project will benefit.


This tutorial shows how to build a serverless API for Page View Counter with Python and Redis. The API will the count page views and show it in JSON format.
The Stack
 - Serverless compute: AWS Lambda (Python)
 - Serverless data store: Redis via Upstash
 - Deployment tool: AWS SAM
Prerequisites:
 - An AWS account for AWS Lambda functions.
 - Install AWS SAM CLI tool as described here to create and deploy the project.
 - An Upstash account for serverless Redis.
Step 1: Init the Project
Run the sam init and then
 - Select AWS Quick Start Templates
 - Select 2 - python3.8
 - Enter your project name: python-redis-example
 - Select 1 - Hello World Example SAM will generate your project in a new folder.
Step 2: Install a Redis Client
Our only dependency is redis client. Install python redis via pip install redis. Also add redis to requirements.txt.
Step 3: Create a Redis Database
Create a Redis database from Upstash console. Free tier should be enough. It is pretty straight forward but if you need help, check getting started guide. In the database details page, click the Connect button. You will need the endpoint and password in the next step.
Step 4: The function Code
Edit the hello-world>app.py as below:
import json
import redis
r = redis.StrictRedis(
host='YOUR_REDIS_ENDPOINT',
port='YOUR_REDIS_PORT',
password='YOUR_REDIS_PASSWORD',
charset="utf-8",
decode_responses=True)
def lambda_handler(event, context):
counter = r.incr('counter')
 return {
 "statusCode": 200,
 "body": json.dumps({
 "counter": counter,
 }),
}
Replace the "YOUR_REDIS_ENDPOINT", "YOUR_REDIS_PORT" and "YOUR_REDIS_PASSWORD" with your database's endpoint and password which you created in the Step 3. The code simply increments a counter in Redis database and returns its value in json format.
Step 5: Deployment
Now we are ready to deploy our API. First build it via sam build. Then run the command sam local start-api. You can check your API locally on http://127.0.0.1:3000/hello
If it is working, you can deploy your app to AWS by running sam deploy --guided. Enter a stack name and pick your region. After confirming changes, the deployment should begin. The command will output API Gateway endpoint URL, you can check the API in your browser.
You can also check your deployment on your AWS console. You will see your function has been created. Click on your function, you will see the code is uploaded and API Gateway is configured.
Notes
 - Check the template.yaml file. You can add new functions and APIGateway endpoints editing this file.
 - It is a good practice to keep your Redis endpoint and password as environment variable.
 - You can use serverless framework instead of AWS SAM to deploy your function.

Word Origin & History
suffix attached to verbs to mean their action, result, product, material, etc., from O.E. -ing, -ung, from P.Gmc. *unga (cf. O.N. -ing, Du. -ing, Ger. -ung). Originally used to form nouns from verbs and to denote completed or habitual action. Its use has been greatly expanded in M.E. and Mod.Eng. The
other use of -ing is to form the prp. of verbs, and in this sense it developed from O.E. -ende (cf. Ger. -end, Goth. -and, Skt. -ant, Gk. -on, L. -ans). It evolved into -ing in 13c.-14c.

Three months after planting, all rhizomes of hardstem bulrush Schoenoplectus acutus and broadleaf cattail Typha latifolia had died (i.e. none had produced shoots). In contrast, California bulrush Schoenoplectus californicus rhizomes were alive in all four areas where they were planted, with 6–31% of individual rhizomes having produced shoots. After 24 months, California bulrush was still present in all four areas and had spread to cover 4–23 m2/site. Methods: In June 2010, one hundred and ninety two rhizomes were planted into four areas within the marsh (16 rhizomes/species/area). Survival was quantified in September 2010. Cover was measured until June 2012. The study areas were flooded for 82–99% of each summer.Study and other actions tested

Manage Lightrun Java agent tags
Tagging enables you to group agents together by using a meaningful name, typically based on common functionality. For example, you can use tags to identify the location and purpose of each agent: Database servers, Staging, and so forth. Additionally, you can apply to each agent multiple tags in any combination.
By applying multiple tags, you can bind actions to an agent before the agent has been launched, and you can apply actions to applications across different sectors. Once an action is bound to a tag, it is implicitly added to all of the agents that possess that tag.
Example
 - Define a tag in the metadata file named "Integration".
 - Add that tag to relevant agents where you're running your application for integration testing.
 - Set integration tests to execute with the Integration tag, in order to debug an integration test failure.
 - List actions by the Integration tag from the CLI with java -jar lightrunc.jar list-actions tag:Integration.
 The output lists all of your agents that inserted actions for integration testing.
Out-of-the-box, agents have a single Production tag. You can:
To create and add a tag to an agent
 1. From the relevant server where the agent is installed, go to the agent.metadata.json file and open it.
 2. Insert tag names within the tags object (which should be nested in the registration object).
 {
 "registration": {
 "tags": [
 {
 "name": "Tag1"
 },
 {
 "name": "Tag2"
 },
 {
 "name": "Tag3"
 }
 ]
 }
 }

 For example, the following JSON applies the tags Production, Main, and East US to the relevant agent.
 {
 "registration": {
 "displayName": "<DISPLAY_NAME>",
 "tags": [
 {
 "name": "Production"
 },
 {
 "name": "Main"
 },
 {
 "name": "East US"
 }
 ]
 }
 }

 Alternatively, tags can be applied using a command line argument as part of the command you use to run the agent with your application.
 Multiple tags can be specified by separating them with commas. For example, you can set them like this:
 java -Dlightrun.registration.tags=myTag1,myTag2,myOtherTag

 3. Save the changes and close the file.
 4. Restart the application.
 Important
 Changes to this file aren't detected until the application is restarted.
To view all tag details from the Management Portal
Log in to your Lightrun account and navigate to Entities->Tags.
The Tags screen loads, appearing similar to the example below.
Manage tags
The details displayed in the Tags screen are as follows:
Column Description
Name The tag name
Actions A list of actions currently attached to this tag.
Agents A list of agents with which this tag has been associated.
To view tags from the CLI
 1. Install the Lightrun CLI tool
 2. Run the command java -jar lightrunc.jar list-tags:

Mark Nozzle Orientation on Dish Fabrication:
I would like to explain in this post how to mark the nozzle on the dishes or heads through the use of fabrication methods and terms. By using AutoCAD software how to mark the nozzles on the exact position with proper angles and radius as follows.
Nozzle Orientation process in AutoCAD:
- First, observe the dish or head outer diameter with measurement tape or with any other types of equipment as your wish.
- After that plan, the elevation and how many nozzles are required for the dish. I already mention the all the details in the below AutoCAD drawing tutorial you can check the video.
- Then after mark the centre point on the top of dish with a marker by measuring the four parts. That means to divide the 360 degrees into four parts then you get each part 90 degrees.
- Draw one of the horizontal and vertical lines to form a centre point of the top dish.
- consider how many nozzles are required for example in this I am taking 8 nozzles. divide this by 360 degrees then you get each nozzle angle.
- 360 degrees/8 nozzles are equal to 45 degrees.
- Then you get each degree angle of all eight nozzles are 45 degrees
- This is easy to draw in AutoCAD with exact angles coming to fabrication terms it is somewhat difficult the process as follows:
- Mark the dish centre by using a dot-punch
- Check the OCF of the dish
- Example: 5232 mm OCF of the dish
= 5232 mm/360 degrees
= 14.81 degrees (each degree)
4. Example: The radius of the nozzle orientation is 645 mm
5. Mark the radius on the top of the dish with a large divider with the exact measurement and you can also adjust the measurements.
6. At the end of the dish measure the OCF of the dish after that list out all the angles where you want to place the angles for example:
0 to 60 degrees x 14.81 degrees = 888.6 mm
60 to 90 degrees x 14.81 degrees = 444.3 mm
90 to 120 degrees x 14.81 degrees = 444.3 mm
Like this, you can measure the all the angles with this process.
7. After getting the all the angles mark the distance at the bottom end of the circular dish with measuring tape and marker or dot punch.
8. after intersecting the all the dots with the centre point of the top dish then you can observe the angles on the Radius of the orientation and place the nozzles.
- Check the actual Radius (R)
- Check the pipe sizes equal or not
- Measure the lengths and angles properly with measurement tape
- Maintain the pipe cutting gap should be 10 mm
- After cut the orientation by the plasma torch.
- Fabricate the all the nozzles as per standards sch40, sch80 and ASA 150# SORF flanges Table-E PCD or normal as per client requirements.

welfarism, empirical research, utilitarianism, cost-benefit analysis, subjective well-being
A growing body of research on happiness or subjective well-being (SWB) shows, among other things, that people adapt to many injuries more rapidly than is commonly thought, fail to predict the degree of adaptation and hence overestimate the impact of those injuries on their SWB, and, similarly, enjoy small or moderate rather than significant changes in SWBg in response to significant changes in income. Some researchers believe that these findings pose a challenge to cost-benefit analysis, and argue that project evaluation decision-procedures based on economic premises should be replaced with procedures that directly maximize subjective well-being. This view turns out to be wrong or, at best, premature. Cost-benefit analysis remains a viable decision procedure. However, some of the findings in the happiness literature can be used to generate valuations for cost-benefit analysis where current approaches have proven inadequate.

Bentley begins EV powertrain study; aims fully electric car by 2026
Bentley has launched a three-year research study in a bid to transform electric vehicle powertrains, utilising a fully integrated, free from rare-earth magnet e-axle that supports electric vehicle architectures. The carmaker says this reinforces its ambition to lead sustainable luxury mobility and introduce the first fully electric Bentley by 2026.
The study is titled OCTOPUS, which stands for Optimised Components, Test and simulatiOn, toolkits for Powertrains which integrate Ultra high-speed motor Solutions. The research follows an initial 18-month investigation that Bentley says delivered a technological breakthrough in electric drive systems for high-performance vehicles.
Also Read : Bentley Bentayga Speed, world's 'fastest SUV', teased ahead of global debut
The carmaker says that the resulting electric drive system exceeded the latest permanent magnet motor performance while simultaneously removing the need for both rare-earth magnets and copper windings, delivering a package both cost effective and recyclable at its end of life.

The controller is what handles the roaming, Since they are one two separate controllers and no way to sync them, there will either be no roaming or it will have to disconnect to be able to connect between them. It would be better to not have them named the same since they will most likely want to flag them as malicious.
This is actually incorrect. The decision to roam is made by the client not the AP or the Controller. This is a large part of why roaming is so difficult and unreliable. Some new WIFI standards do include better roaming, but it usually isn't enabled and requires all devices on a wifi network to support it (which is why it usually isn't enabled) or you run into wifi issues.
You can configure settings like a min RSSI to assist the client in making up its mind (in this case by disassociating it) forcing it to re-evaluate and reconnect to what the client decides is the best choice.
There will always be a brief disruption as an client roams. Usually amounting to 1 or 2 pings, that an end user won't notice unless they are doing something like a voice call. you can easily test this by running a continuous ping on a device like a laptop and walking around with it.

Does preoperative percutaneous biliary drainage reduce operative risk or increase hospital cost?
H. A. Pitt, A. S. Gomes, J. F. Lois, L. L. Mann, L. S. Deutsch, W. P. Longmire
Research output: Contribution to journalArticlepeer-review
Abstract
Despite recent advances in perioperative support care, surgery for obstructive jaundice is still associated with significant morbidity and mortality. For this reason, preoperative percutaneous transhepatic drainage (PTD) has been recommended for these patients. This method of management, however, has only been supported by retrospective and nonrandomized studies. Therefore, a prospective, randomized study was performed to determine the effect of preoperative PTD on operative mortality, morbidity, hospital stay, and hospital cost. Thirty-day mortality was 8.1% among 37 patients undergoing preoperative PTD, compared to 5.3% for 38 patients who went to surgery without preoperative drainage. Overall morbidity was also slightly, but not significantly, higher in patients who underwent preoperative PTD (57% versus 53%). However, total hospital stay was significantly longer (p < 0.005) in the PTD group (31.4 days versus 23.1 days). The cost of this excess hospitalization and the PTD procedure at our university medical center was over $8000 per patient. The authors conclude that preoperative PTD does not reduce operative risk but does increase hospital cost and, therefore, should not be performed routinely.

Eventual consistency is everywhere. DNS is the canonical example, but it's becoming more important in mobile applications with sporadic connectivity and databases with high availability requirements. One of the difficulties with these systems is resolving conflicting writes. Some cases allow for last-write-wins, but other domains require a mechanism which doesn't lose data. knockbox is an open source Clojure project that takes data-structure implementations that support automatic conflict resolution, and wraps them up to be used just like any other Clojure seq, set, or map. This talk will explore the motivation behind knockbox, the data-structures themselves, using knockbox with Riak, and issues like garbage collection and synchronization.

Archived:How to get accelerometer data of N900 using Qt
From Nokia Developer Wiki
Jump to: navigation, search
Introduction
In this post, I will demonstrate how to develop a Qt Application that will to get the information of accelerometer sensor at N900 device.
An accelerometer is a device that measures proper acceleration, the acceleration experienced relative to freefall.Single- and multi-axis models are available to detect magnitude and direction of the acceleration as a vector quantity, and can be used to sense orientation, vibration and shock. Micromachined accelerometers are increasingly present in portable electronic devices like mobile phones and video game controllers, to detect the orientation of the device or provide for game input.
Accelerometer Data at N900
The accelerometer data is sysfs file information.Sysfs is a virtual file system provided by Linux 2.6. Sysfs exports information about devices and drivers from the kernel device model to userspace, and is also used for configuration.
The three coordinates of accelerometer sensor is in a text file provided on one line and separated by white space. This file is at path below:
/sys/class/i2c-adapter/i2c-3/3-001d/coord
The values are in mG (milli G). 1000 = 1 G. The g-force experienced by an object is its acceleration relative to free-fall like described above.
At N900 device , the values are connected to the position showed below.
PostN900Accelerometer.png
The Code
 - At starts, i created a QThread. This thread will read the file with data at all the time.
class aThread : public QThread {
 Q_OBJECT
public:
 aThread();
 void run();
 QString x;
 QString y;
 QString z;
public slots:
 void getXYZ();
 void process_data();
signals:
 void dataProcessed(QString,QString,QString);
private:
 QString data;
};
 - At implementation of our thread , the getXYZ() method is called always.
void aThread::run() {
 int a=1;
 while(a)
 {
 getXYZ();
 }
}
 - This method open the file, read and process the string found on the file.
void aThread::getXYZ() {
 QFile file("/sys/class/i2c-adapter/i2c-3/3-001d/coord");
 if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
 return;
 QTextStream in(&file);
 data = in.readAll();
 process_data();
}
 - Then, in the processing of information the string found is splited by the white spaces creating three different strings.These strings are the X,Y,Z coordinates of accelerometer.The signal dataProcessed() is emitted to allowing that other class can connect yours slots to this signal.
void aThread::process_data() {
 QStringList data_splited = data.split(" ");
 x = data_splited[0];
 y = data_splited[1];
 z = data_splited[2];
 emit dataProcessed(x,y,z);

Users who often need to travel will pack the daily shampoo and hair care travel containers to travel, but as a daily chemical product, they can't just be packed in any bottle. Because some of the ingredients will react with some plastics.
When developing shampoo and hair care travel kits, the compatibility of the inner material and the packaging material will be considered while the particularity of the inner material will be considered. Compatibility refers to whether the inner material and packaging will react, causing changes in the inner material or packaging. The particularity of the internal material mainly refers to the nature of the internal material that cannot withstand light or heat. Therefore, when the packaging is developed, it will be considered from whether the packaging material and inner material need to be protected from light. Generally, the shampoo and hair care travel kits on the market are divided into high permeability bottles of PET, PETG, AS, PE or PP opaque bottles, and PE or PVC hoses. High-permeability bottles PET or PETG are relatively common materials, basically can contain most water, milk, and toiletries.
The general types of travel containers:
1. Travel spray bottle: it can spray mist-like liquid, so it is not suitable for other moisturizing lotion or thicker lotion.
2. Flip-type sub-bottle: the bottle is made of hard PET material, suitable for toner, liquid essence, makeup remover, and not suitable for sticky products such as lotion, shampoo, conditioner.
3. Sub-bottle with aluminum cap: the bottle body is also hard PET material, and the applicable type is the same as above. There is a plastic cap in the bottle cap, and there are also small holes in the plastic cap, so there is no need to worry about pouring too much toner at a time.
4. Soft tube sub-bottle: it is made of soft PET resin material, so it is convenient to squeeze viscous emulsion, which can reduce waste, facilitate the use. And it is suitable for sub-packing facial cleanser, conditioner, shower gel, hand cream, toothpaste, etc.
5. Perfume sub-bottle: it can be divided into four parts: aluminum cap, aluminum bottle shell, spray head and glass bottle body for perfume.
Zhongshan Xinrun plastic products Co., Ltd is a professional plastic bottle company. We provide decorative plastic pump bottles, decorative plastic shampoo bottles, 10ml plastic bottles wholesale and etc. Want to know more? Please contact us.

Speaker-Dependent Speech Recognition Based on Phone-Like Units Models --- Application to Voice Dialing
This paper presents a speaker dependent speech recognition with application to voice dialing. This work has been developed under the constraints imposed by voice dialing applications, i.e., low memory requirements and limited training material. Two methods for producing speaker dependent word baseforms based on Phone Like Units (PLU) are presented and compared: (1) a classical vector quantizer is used to divide the space into regions associated with PLUs; (2) a speaker independent hybrid HMM/MLP recognizer is used to generate speaker dependent PLU based models. This work shows that very low error rates can be achieved even with very simple systems, namely a DTW-based recognizer. However, best results are achieved when using the hybrid HMM/MLP system to generate the word baseforms. Finally, a realtime demonstration simulating voice dialing functions and including keyword spotting and rejection capabilities has been set up and can be tested online.

Difference Between Gravity Filtration and Vacuum Filtration | USA Lab
Difference Between Gravity Filtration and Vacuum Filtration | USA Lab
Posted by USA Lab Equipment on Nov 19th 2021
If you work in any kind of lab space, you probably already know about the solvent filtration process. If you run a small lab or if you're a student, you may not have had the chance to operate multiple types of filtration systems yet, though. Keep reading to discover the difference between gravity filtration and vacuum filtration along with the benefits of each for your experiments.
Vacuum Filtration Process
As the name implies, vacuum filtration utilizes the power of a vacuum source. Vacuum filtration most commonly uses a Buchner funnel and flask as well as some specialty filter paper. You also need thick-walled tubing to connect your Buchner filter and vacuum source. If you wish to collect a solid material through the filtration process, vacuum filtration is a fast and effective method. However, don't use vacuum filtration if you want to collect a liquid material afterward. Any solvent tends to boil off during the reduced-pressure process.
Gravity Filtration Process
Gravity filtration relies on gravity to do most of its work. This process involves setting up a funnel and paper filter on top of a flask. Gravity filtration is vital for separating a liquid from a solid when you want to preserve the liquid material. When decanting isn't an option, gravity filtration is the go-to method. Gravity filtration is a slower process, but lab technicians still rely on it to this day for experiments.
The Differences Between Filtration Methods
The main difference between vacuum and gravity filtration is their timeliness and how they operate. One method uses a vacuum source to power the filtration while the other uses gravity. This results in vacuum filtration being faster and more convenient. Still, it doesn't fit every experiment. Gravity filtration is the gentler of the two methods, and it can preserve both solid and liquid parts from a mixture. Each filtration method has its benefits and drawbacks.
As a lab technician, it's pivotal to understand the differences between vacuum and gravity filtration to know which method to use for your tasks. If you need to stock up for either filtration system, check out USA Lab Equipment for everything you need.

Interest continues to grow in our industry for the flexibility and ease-of-use that comes with history-free direct modeling. Unfortunately there is still much confusion out there about just what direct modeling is and what value it adds to the process of product development. One of the many high value opportunities that come with direct modeling is in "large assembly design and management". Direct modeling technology can offer some unique advantages over traditional history-based modeling that can greatly improve design, interaction and management of large assemblies.
Based on the technology behind direct modeling, large assembly design and management can be fast and easy. As direct modeling does not record the modeling steps used to create the model, memory requirements and file sizes can be considerably smaller than with traditional parametric history-based modeling. With PTC CoCreate Modeling, for example, I have found file sizes to be 60% to 80% smaller than the same model created in most any traditional history-based system. This would indicate that these parts and assemblies will also consume much less memory when loaded.
In a traditional history-based CAD system, an assembly is basically a collection of references and relationships to other individual history trees. These history trees represent individual parts and sub-assemblies The history trees can be large and complex. The assembly references and relationships between these trees can be even more complex. With direct modeling an assembly is simply a collection of solid models that are organized in a hierarchical structure. There is no history tree. There are no hidden references or relationships. What you see is what you get. It's as simple as that.
I've been doing some large assembly testing with several different CAD systems. It has been startling to witness how poor many of the most popular CAD tools perform with large assemblies, even with "dumb solids". The assembly that I am using in this example is made up of 29,455 part and assembly objects. The STEP file of the entire assembly comes out at just over 302mb. The native CoCreate package file of the entire assembly comes in right at 100mb. This is not a large assembly compared to many of the assemblies I have witnessed CoCreate users working with. Most CoCreate users would consider a large assembly to be somewhere around 100,000 to 250,000 parts. (By the way, the native geometry resolution/accuracy of a model developed in CoCreate Modeling is 1.0E-6 mm by default – about 2500 times higher accuracy than any other CAD system on the market, and yet it is still possible to manage these large assemblies.)
Below is a picture of the assembly I have been working with. It comes from a company in Europe. This is a coagulator used in the cheese making process. CoCreate Modeling was used from beginning to end to support the design process.
For the video below I loaded this assembly in its entirety. All parts are loaded as high accuracy solid models. None of the parts were loaded as lightweight, graphics only or in some suppressed mode. Based on the privileges controlled by the PDM system, every part and/or assembly can be quickly and easily modified. As you will see, in-context design is simple and fast, even in the context of 30,000 other parts.

This paper presents a combined experimental and numerical method to simulate the liquid flow in a packed bed. Two types of the experiments, i.e. liquid percolation without gas flow and liquid flow with gas cross flow, were conducted using a three- or two-dimensional cold model, respectively. A mathematical model has been proposed for the numerical simulation of the liquid flow. This model was developed using a force balance approach combined with stochastic considerations, in which the liquid flow was treated as a discrete phase with stochastic dispersion based on the experimental observations. Accordingly, the interactions between liquid and the packed bed, and liquid and gas have been experimentally investigated and then were used to determine the model parameters involved in the model. The behavior of the liquid flow in packed beds can numerically be simulated using the proposed model. A reasonable agreement has been achieved between the model predictions and the experimental measurements.

PROVIDING EARLY CONSTRUCTABILITY REVIEW FOR THE WITHERSPOON RENOVATION PROJECT.
Design & Engineering
Virtual Design & Construction (BIM Modeling)
Mechanical and Plumbing Construction
This project consisted of renovating the existing 12 story office building located a block off of Broad Street into a modern loft-style apartment building.
The real challenge on this project was the lack of as-built structural information available to identify the existing HVAC and plumbing routing structures. Through extensive field investigation, our team ran into additional challenges such as asbestos, existing utilities, and varying structural steel from floor to floor. Through this investigation, it was also determined that the existing mechanical spaces were too small for the installation of new equipment.
The foreman recognized this and worked with owners and the CM to reconfigure existing equipment and identify systems in adjoining spaces that could be removed.
Through early constructability review, our team was able to identify existing openings for our routings that not only provided a path for us but other trades. In addition, reconfiguring systems and creating space in areas around the mechanical spaces allowed us to maximize the aforementioned routing approach, ensure all equipment was located correctly, and decrease the amount of piping required. These early findings eliminated the need for re-designs & provided coordination synergy.

Jubile of Saints Louis and Zelie : we talk about it !
Saints Louis and Zelie lived holiness in the ordinary life of a married couple and a family. Their exemple show us how to go deeper in our prayer life.
Resources to download and share.
What is a jubilee?
A jubilee is a great celebration in the Catholic Church that celebrates an event, a particular anniversary.
It was Pope Boniface VIII who inaugurated the first jubilee of history in the year 1300. History shows with what enthusiasm the people of God have always lived the jubilee years, seeing in them a circumstance where the invitation of Jesus to conversion is heard more intensely. We remember especially the last jubilee of Mercy (2015-2016) or that of the Year 2000.
In the same way that the Pope inaugurates Jubilees for the Universal Church, each bishop can do it, on the occasion of a particular celebration, in his diocese.
Why a jubilee at Alençon ?
Alençon is first and foremost the wedding site of Saints Louis and Zélie: after having met in Alençon on the Sarthe bridge in the spring of 1858, they were married at the city hall on July 12 at 10 pm and at midnight at the Church of Notre-Dame (now Basilica).
It was then in Alençon that the nine children of the Martin family were born. It is after all the place of family life until the death of Zélie in 1877.
The Church wanted to give Saints Louis and Zélie Martin as an example to all the couples and families of today: it is for this reason that they were canonized by Pope Francis, just two years ago, on October 18, 2015. This is the first married couple canonized together in the history of the Church.
This jubilee of the 160th anniversary of their marriage will give all the faithful the opportunity to discover the lives of Saints Louis and Zélie at the very places where they lived. Pilgrims will be able to receive the special graces related to each Jubilee Year.
This jubilee will also give more opportunity to know about Saints Louis and Zélie. Given that they are the parents of St. Therese of Lisieux, the illustrious « greatest saint of modern times » (St. Pope Pius X), the Christian people are invited to discover further the life of this couple that is still little known.
Receive the Plenary Indulgence
A plenary indulgence is a grace offered by God for one-self or for someone deceased. It will be possible to receive it at the Shrine of Alençon during the Jubilee Year. It is a reparation, a removal of all of the temporal punishment due to sin.
In order to receive it, the faithful must be in a state of grace, be disposed interiorly to the complete detachment from sin; to have confessed, to have received the Holy Eucharist, to pray for the intentions of the Holy Father, and to make a pious pilgrimage to the Shrine of Alençon during the Jubilee Year.

Is there any general idea of what percentage of loan words come from which languages? I always thought the majority of them came from English, but I keep seeing more and more that originated in Germany and Portugal.
share|improve this question
When you say "loan words", I'm assuming words from the west within the last century? Otherwise, if you include Chinese, then the breakdown is going to be more than half Chinese. – Jesse Good Sep 27 '12 at 2:04
I suspect "Welcome to Japanese" has a breakdown of how many words came from what language. But rather than a mere pie chart, I'd love to see how many words came from which languages broken down by when they were imported. – Andrew Grimm Sep 27 '12 at 2:53
_USER_ What I mean is words that are written using katakana, not kanji. Is that what you meant? – LucasTizma Sep 27 '12 at 4:00
You could count this in a number of ways but if the there is no immediately available stat (which I doubt), then possibly the easiest meaningful approach would be to take a JLPT N1 +N2 textbook, find the chapters on loanwords, list them up, allocate language of origin and a percentage there-on to each language: On the assumption that these lists comprise the most commonly used loanwords and in turn, a high %age of the time that a Japanese speaker uses a loan word it is one of this population, you should be able to calculate a conservatively accurate analysis of loanwords by language of origin. – Tim Sep 27 '12 at 4:44
I like this question and would love to have a good answer. If you could incorporate your comment into the body of the question, we might be lucky enough that the question stays open and gets answered. – Earthliŋ Sep 27 '12 at 10:03

This puts English derived words at something like 80% of foreign origin words (this would exclude 漢語{かんご}). It also has some lists of words separated by origin (leaving out English-derived words).
Let's assume for a moment that this list is in some way representative of non-English derived katakana loanwords. A rough calculation suggests that the most common origin is French (~26%), followed by German (~20%), Portuguese (~11%), Dutch (~9%), Latin (~9%), Italian (~8%), and Russian (~7%), Korean (~5%).
This list also marks the period at which words were introduced. What if we only include words marked as Meiji period or earlier? That cuts the list down to less than half size. Unsurprisingly, Portuguese and Dutch feature heavily:
Portuguese (~25%), Dutch (~20%), Korean (~12%), French (~11%), German (~11%), Ainu (~6%), Greek (~5%).
I've included the words listed for Korean and Ainu in the statistics although I would think that this word list isn't at all reflective of the actual relationship between Japanese and these languages. For the European languages, however, Portuguese and Dutch early on and words from French and German becoming more prominent later makes perfect sense from a historical perspective.

Page 12 of "Welcome to Japanese", by Kenneth Henshall with Junji Kawai, says that 45% of words are native Japanese, 45% are Chinese, 8% are English, and 2% are other. It mentions Portuguese and German as examples of other languages that have contributed words to Japanese.

The normal spectral emissivity of niobium strip specimen is measured using a new pulse-heating reflectometric technique. The hemispherical spectral reflectivity of the surface of a strip tangent to an integrating sphere is determined by a high-speed lock-in technique. At the same time, the radiance temperature of the strip is measured by the multi-wavelength high-speed pyrometer from approximately 1000 K to the melting point. Details of the measurement method and of the related calibration techniques are reported. Results of the normal spectral emissivity of niobium at 633, 753, 827, and 905 nm from room temperature to its melting point are presented. The accuracy of spectral emissivities is estimated better than 5%.

1. The size of a door frame is determined after allowing a margin of __________ all-round.
a) 1 mm
b) 3 mm
c) 5 mm
d) 7 mm
Explanation: A door frame consists of horizontal and vertical members forming an enclosure. The size of a door frame is determined after allowing a margin of 5 mm to both the sides and the top of the door opening. This is one of the recommendations laid down by the Indian Standard.
2. Which of the following frames are used only for those residential buildings where more funds are available?
a) Timber frames
b) Aluminium frames
c) Steel frames
d) Stone frames
Explanation: Aluminium frames are used only for those residential buildings where more funds are available because of their large costs. Timber frames can be easily attacked by termites. Stone frames are used in villages where the stone of good quality in required size is available.
3. The cross-sectional area of the head and the post of a door frame is generally kept the same.
Explanation: The cross-sectional area of the head and the post of a door frame is generally kept the same. The top horizontal member of the door frame is known as the head while the vertical members are known as posts.
4. Which of the following statements about concrete frames is false?
a) They are replacing timber frames in urban areas
b) They cost less than timber frames
c) They cost more than timber frames
d) They are cheaper than iron frames
Explanation: Concrete frames are nowadays replacing timber frames in urban areas due to large costs of timber frames. Also, timber frames decay very readily. Concrete frames are cheaper than timber frames as well as than iron frames.
5. The thickness of a timber frame may vary between _______
a) 20-35 mm
b) 60-75 mm
c) 20-35 cm
d) 60-75 cm
Explanation: Depending upon the size of the door opening and the type of timber used, the thickness of a timber frame may vary between 60-75 mm. The same thickness is used for the horizontal and vertical members of the door frame.
6. The width of a timber door frame is _______ if the shutter is provided only to one side of the door.
a) 10 mm
b) 50 mm
c) 100 mm
d) 200 mm
Explanation: The width of a timber door frame is 100 mm if the shutter is provided only to one side of the door. This is the general case of a timber frame. However, if the shutter is provided to both the sides of the frame, then the width is taken 125-140 mm.
7. The width of rebating of the timber frame at its outer edge varies between ________
a) 12.5-15 mm
b) 2.5-13 mm
c) 8.1-9.2 mm
d) 18.5-20.5 mm
Explanation: The width of rebating of the timber frame at its outer edge varies between 12.5-15 mm. In this case, the depth is equal to the thickness of the shutter. However, the depth of rebating of the timber frame at its inner edge is equal to 10 mm.
8. Which of the following is not a type of joint between the head and the post of the timber frame?
a) Closed mortised and tenoned joint
b) Open and pin joint
c) Pin and tenoned joint
d) Dovetailed joint
Explanation: The various types of joints between the head and the post of the timber frame are – closed mortised and tenoned joint, pin and tenoned joint, and dovetailed joint. However, Indian Standard recommends a dovetail joint out of these three types.
9. Which of the following is an anti-termite solution?
Explanation: Aldrex is an anti-termite solution. It is added to coal tar which is then rubbed on all the parts of the timber frame which are in contact with the masonry. This prevents the timber from the attack of termites. Acetone is a volatile solution and hence is soaked by the wood which makes it ineffective against the attack of termites.
Explanation: The above figure represents a door frame. In this figure, A represents the head, B represents post, C represents rebate and D represents holdfast. The post is the vertical member of a door frame. It is also known as the jamb.

Besides, what happens when brushes go on washing machine?
If your brushes are worn or damaged when you come to use your washing machine it will fill up with water, appear to sit idle for the duration of the wash and spin cycle (because the drum won't turn), and then drain out the water, and when you open the door of the machine to remove your clothes they will still be
Likewise, how do I know if the motor has gone on my washing machine? The five most common signs of motor issues are listed below.
 1. Washer Won't Pump or Spin. It may happen that the washing machine fails to pump water in and out, as well as spin.
 2. Pumps, but Won't Spin.
 3. Washer Won't Agitate.
 4. Clothes Still Wet.
 5. Problems in Every Cycle.
In this way, how long do brushes last on a washing machine?
Carbon brushes typically last between two and ten years on most machines depending on frequency of use.
What happens if you put carbon brushes in wrong way?
Have brushes been fitted correctly The holders are keyed so that they will only fit in the correct motor and the correct way. If fitted the wrong way round then only the tip of the brush trails against the commutator instead. This would cause a loud ratchety sound and excessive sparking or lack of power.
Related Question Answers
How do you know if carbon brushes are bad?
Similar to a tool that won't start, check your carbon brushes for any heavy wear or signs of damage. If your brushes are clear, there may be damage to your tool's commutator or the rest of the assembly. Discoloration, buildup and even melted insulation are signs that these parts are the root cause.
How do you fix a washer that won't spin?
If your washer fills with water but doesn't agitate, the problem is likely to be a faulty lid switch, a broken belt, or a problem with the motor. (Note: Direct-drive washing machines do not have belts.) To diagnose the problem, do the following: 1 Check the washing machine's spin cycle.
How do you tell if brushes need replacing?
As a general rule, if either brush has worn to about a quarter inch long, it is time to replace it. If the carbon (a brush is essentially a carbon block with a metal spring tail) shows any signs of breakage, crumbling, or burning, the brush needs replacing.
Why do carbon brushes wear out?
Here are three of the most common reasons for rapid carbon brush wear: Poor Commutator or Ring Condition: A rough, out of round, or otherwise poor contact surface can cause accelerated brush wear. A poor commutator condition can lead to both electrical and mechanical wear of the carbon brush.
How do you change brushes?
Select a painting, erasing, toning, or focus tool. Then choose Window > Brush Settings. In the Brush Settings panel, select a brush tip shape, or click Brush Presets to choose an existing preset. Select Brush Tip Shape on the left side and set options.
How do I know if my electric motor brushes are bad?
When they first start to go out, switches and carbon brushes can present either (or both) of the following two symptoms :
 - Off-and-On Use.
 - Decreased Tool Power.
 - Tends to Run Fine After Starting.
 - Off-and-On Use Worsens Steadily.
 - Off-and-On Use During Operation.
 - Shaking or Slapping the Tool Helps.
 - Banging Sound.
Why is my washing machine sparking underneath?
If the machine is filling and emptying as normal but the drum isn't turning, or if it's making some sort of spluttering noise, or if you can see sparking coming from underneath the front of the machine these are all likely to be caused by worn brushes and you'll need to replace them.
How much is a new washing machine motor?
Consider that most new washing machines cost roughly $600, and you will find that the washing machine motors are about $100.
How long on average does a washing machine last?
11 years
How much does it cost to repair washing machine?
If your washer breaks, it's probably worthwhile to have it repaired or replaced. Depending on what you need fixed, repairs will most likely cost between $120 and $500.
Why is my washing machine making a banging noise when spinning?
If the noise primarily happens during the spin cycle the bearing is likely the problem. If the washer is making a loud noise the drive pulley might be worn out, cracked, loose or bent. If the washer is making a loud noise in the spin cycle, the clutch assembly might be worn out.
Why is my washing machine so loud when spinning?
A washer making a loud noise during spin cycle can also be caused by a faulty drive pulley. The pulley is what the belt (if applicable to your washer) rides on to spin your washers tub. The pulley can be made of plastic or metal. It could be simply worn out or just loose.
What causes excessive sparking at the brushes?
Sparking can be caused by numerous conditions like motor overload, vibration, high humidity, worn brushes and worn commutators. When checking for sparking or arcing, a good visual inspection of the commutator and brushes will have to be performed. Check for worn brushes.
How do I know if the motor is broken on my washing machine?
The five most common signs of motor issues are listed below.
 1. Washer Won't Pump or Spin. It may happen that the washing machine fails to pump water in and out, as well as spin.
 2. Pumps, but Won't Spin.
 3. Washer Won't Agitate.
 4. Clothes Still Wet.
 5. Problems in Every Cycle.
What causes a washing machine motor to burn out?
Worn bearings can place a heavy load on a motor and cause it to burn out prematurely. Any of the bearings in the washing machine's transmission, the tub bearing or the sleeve bearings in the motor itself can cause early motor burnout.
Why is my washing machine drum not turning?
If your washer fills with water but doesn't agitate, the problem is likely to be a faulty lid switch, a broken belt, or a problem with the motor. (Note: Direct-drive washing machines do not have belts.) To diagnose the problem, do the following: 1 Check the washing machine's spin cycle.
What is the use of carbon brush in motor?
A carbon brush is a sliding contact used to transmit electrical current from a static to a rotating part in a motor or generator, and, as regards DC machines, ensuring a spark-free commutation.
How long do motor brushes last?
What is normal brush life. As an estimate, 7,500 hours brush life is normal for general purpose, medium horsepower DC motors with good commutator film with commutator surface speeds in the range of 2,500 to 4,000 feet per minute. The minimum life might be 2,000 to 5,000 hours with 10,000 hours being about maximum.
