Soldering Iron Not Heating Up – 3 Most Common Reason and its Solutions
Are you facing this issue of your Soldering iron not heating up. Their are more reasons to not working or not heating up the soldering iron. So let we see this most common reasons and its solution to heating up your soldering iron again. First of all you need to know about how a soldering iron is working and also what is present inside of the soldering iron, Lets check.

Soldering iron is an electronic / electrical device that can be used to solder the Lead to the electronics boards or the surface of any copper plates. The soldering iron start to heat after plugin to the alternating current AC. The technical term of soldering iron working is very easy to understand, You all are know about the function of old water heater rods. If you are hearing in first time, i will explain a little bit. The water heater or the water heating rod also contains tungsten coin wounded on the metallic rod.
The tungsten wires has the property of high resistance and durability. In old bulbs the tungsten is used as the filament to get light. Those produce high level of heat and also light. The tungsten coil is wounded on the metallic foil or rod. The more turns of the coil means more resistance to pass the electricity. The one end is connected to the phase and another one is connecting to the neutral. In that time the circuit get complete and the electricity passes through the coil. When the electricity passing through this coil it gets heat up. This is applied on the soldering iron and also the water heater devices. Any problems occurring inside or outside of the soldering iron may stop working or stops heating up.
Why soldering iron not heating up
 - The most common reasons of soldering iron is not heating up are listed below. The exact solution also attaching with the problems.
Reason 1: Lower voltage
Most of the electrical and electronic devices are working with AC voltage rating of 220V with 50Hz. The soldering iron will provide maximum heat output at the time of stable electric voltage. If the required AC voltage is not get by the coil inside of soldering iron, takes too much time to heat or not heating very well, so avoid soldering when the voltage is below 200v AC.
In this low voltage time keep your inverter ready to use. The inverter can deliver constant voltage rate, this enough to do work with your soldering iron. Take an extension from the inverter ac supply and connect your soldering iron on it. Continue work without any angry.
Reason 2 : Broken wire of soldering iron
The most common reason is soldering iron wire problems, after long usage of soldering iron may cause the damage in wires. Unusual bending or stretching of wire may cause internal disconnection of copper connection between wires. This will lead to the disconnection of soldering iron from the main power supply. Some time this may cause accidental fire of short circuit of both internal wires.
To solve this issue replace the AC cord. Before changing the AC, test the wire is working properly or not. Test the continuity of the wire using a multimeter to verify the issue. If the beep sound is not producing the multimeter means wires disconnected internally or damage occurs inside, so without any doubt change the AC cord.

Reason 3 : Internal coil problem
If the internal coil of the soldering iron get burns or damaged, will cause permanent damage of your soldering iron. If it happens the soldering iron won't heating up. This can be happened due to the over voltage or poor quality of the soldering iron.
To solve this problem replace the heating coil of soldering iron. You can easily replace it by removing the screws of the soldering iron and detach the connecting wire. Then replace the new purchased heating coil.

text: The influences of low-dielectric interfacial layers on the dielectric properties of Pt/(Ba,Sr)TiO3/Pt capacitors were investigated before and after postannealing. The interfacial layer is believed to be the intrinsic dead layer (low-dielectric layer) due to the termination of chemical bonds of the (Ba,Sr)TiO3 (BST) material at the interfaces. The dielectric constant of the capacitor decreases with decreasing BST film thickness owing to the low dielectric constant of the dead layer. The dead-layer capacitance varies with processes such as film deposition temperature, and postannealing. Higher deposition temperatures result in a larger dead-layer capacitance and a higher bulk dielectric constant. Although annealing under a N2 atmosphere is less effective in reducing the dead-layer effect than under an O2 atmosphere, it is more effective in increasing the bulk dielectric constant. Therefore, a N2, rather than an O2 atmosphere, results in a larger increase in the overall dielectric constant. © 2000 American Institute of Physics.

Modeling Pit Lake Flooding After Mine Closure
S. Jordana[1], A. Nardi[1]
[1]Amphos 21, Barcelona, Spain
Most of mining works, either on the surface or in the underground, demand continuous groundwater pumping in order to operate under dry conditions. When the mining activity stops, dewatering also stops and mining facilities begin to flood, quite quickly at the beginning but becoming slower as the water level in the pit lake rises. The rise of the surface of the lake decelerates due to the bigger evaporation of water and the decrease of the groundwater pressure gradient towards the lake. Both effects are induced precisely by the surface lake rise. Therefore, incorporate this lake-flooding phenomenon into a hydrogeological model requires handling a nonlinear problem. The resulting model is able to recreate under transient conditions the pit lake generation.

Important and very rare plan of Bury St. Edmunds by A. Downing
A large and detailed copper engraved plan of Bury St. Edmunds, Suffolk, drawn and published by Alexander Downing in 1741, engraved by W.H. Toms, engraver in Union Court, and sold by Samuel Matson, Bookseller at Bury. Oriented with north to the right of the page, the plan is dedicated by Downing to 'To the Right Worshipful the Alderman, Recorder, Capital Burgesses, and Common Council of the Borough of Bury St. Edmunds, in the County of Suffolk. This plan is humbly Inscribed by their Worships most humble Servant Alex: Downing'.
A title cartouche appears in the upper left corner, two large vignette illustrations of 'The Cross' and 'Abbey Gate' in the lower corners, a compass rose, coat of arms, a mileage scale and a key from 1 to 55 with street names, another key from A to W with important buildings. At the bottom of the plate the participating persons are mentioned: 'Published by the Proprietor Alexander Downing, April 24th, 1741. & sold by Sam. Watson, Bookseller at Bury, and W.H. Toms, Engraver in Union Court near Hatton Garden, Holborn.'
This is first state of the map, published by A. Downing itself. There was a second state published by J. Rocque in 1761. We only could locate one copy of this first state in the Library of Yale, non in COPAC (British Libraries).
Evidence of two vertical old folds, very good condition. It is quite unusual to find a separate published map in such preservation.

Can LLT heartbeats communicate between NICs with different device names?
One 2-node vcs cluster, the heartbeat NICs are eth2 and eth3 on each node,
IF eth2 on node1 down, and eth3 on node2 down. Does this mean the 2 heartbeat Links both down, and the Cluster is in split brain situation?
Can LLT heartbeats communicate between NIC eth2 and NIC eth3?
Since the 《VCS Installation Guide》requires the 2 heartbeat Links in different networks.We should put eth2 of both nodes in the VLAN (VLAN1), and put eth3 of both nodes in another vlan (VLAN2). So in this situation heartbeats cannot communicate between eth2 and eth3.
But, in a production cluster system, we found out the 4 NICs--eth2 and eth3 of both nodes are all in a same VLAN. and this lead me to post the discussion thread to ask this question:
IF eth2 on node1 down, and eth3 on node2 down, What will happen to the cluster (which is in active-standby mode)?

Sustainability considerations have placed increasing emphasis on the energy efficient operation and control of temperature control systems. It is estimated that the use of advanced control structures could lead to valuable savings in energy expenditure (up to 15-20 %). This work considers the problem of developing a model predictive control (MPC) algorithm for temperature control in buildings. To this end, a cascade control structure was designed to regulate the room temperature subject to heat load disturbances, such as outdoor conditions or changes in the internal gains (i.e., number of people in a room). The inner loop of the cascade control structure involved controlling key variables of a vapor compression cycle (VCC), namely the superheat and supply air temperature (from the evaporator), by manipulating the compressor speed and valve opening (components in the VCC). Linear inputoutput models were appropriately identified for the VCC using a detailed first-principles model (adapted from Thermosys) for eventual utilization in a predictive control design. Then, closed loop simulations were performed by interfacing the VCC model with EnergyPlus (developed by the U.S. Department of Energy), which was used to model realistic room temperature behavior. The control performance using a predictive controller (in the inner loop) was then evaluated against PI control.

text: Xylem and phloem are the two main conveyance systems in plants allowing exchanges of water and carbohydrates between roots and leaves. While each system has been studied in isolation for well over a century, the coupling and coordination between them remains the subject of inquiry and active research and frames the scope of the review here. Using a set of balance equations, hazards of bubble formation and their role in shaping xylem pressure and its corollary impact on phloem pressure and sugar transport are featured. The behavior of an isolated and freely floating air bubble within the xylem is first analyzed so as to introduce key principles such as the Helmholtz free energy and its links to embryonic bubble sizes. These principles are extended by considering bubbles filled with water vapor and air arising from air seeding. Using this framework, key results about stability and hazards of bubbles in contact with xylem walls are discussed. A chemical equilibrium between phloem and xylem systems is then introduced to link xylem and osmotic pressures. The consequences of such a link for sugar concentration needed to sustain efficient phloem transport by osmosis in the loading zone is presented. Catastrophic cases where phloem dysfunction occurs are analyzed in terms of xylem function and its vulnerability to cavitation. A link between operating pressures in the soil system bounded by field capacity and wilting points and maintenance of phloem functioning are discussed as conjectures to be tested in the future.


In "The Dragon and the Wolf" (Game of Thrones, S07E07), Bran tells Sam that Jon is actually Rhaegar Targaryen and Lyanna Stark's son, and that his name should've been Jon Sand. Of course, Sam corrects him by saying Jon isn't a bastard at all.
But is "Sand" really what Jon's last name would've been if Rhaegar and Lyanna wouldn't have been married? On what basis is a bastard named (last name)?
IF Jon had been a bastard and acknowledged by his father he would have taken / been given the common name for bastards in the region where he would have been born.
Lyanna gave birth in Dorne and the bastard's names go by region of birth in GOT.
 - Flowers: The Reach
 - Hill: The Westerlands
 - Pyke: Iron Islands
 - Rivers: The Riverlands
 - Sand: Dorne
 - Snow: The North
 - Stone: The Vale of Arryn
 - Storm: The Stormlands
 - Waters: The Crownlands
 - 1
 If that's the case, did Ned ever say that Jon was born in the north, hence naming him Snow? – SrB Aug 28 '17 at 18:25
 - 3
 I don't recall Ned ever saying where Jon was born. He just brought him home and claimed him as his bastard. No additional explanation would have been sought or required. – Paulie_D Aug 28 '17 at 18:27
 - Another strengthening point for the answer is Ellaria Sand and the Sand Snakes, which play off the Sand name for bastards. – DariM Aug 28 '17 at 22:08
Bastards are not named for where they are born but where they are raised.
Remember, Ned is claiming that Jon is his own child. While he was physically born outside of the North, he was brought to live in the North by a Northman. It has more to do with who the bastard was born to and where they live then where they are actually born.
Explanation of Bastard Naming:
Examples of bastard naming:
The surname a bastard received appears to be connected to the location the child is raised, though this is not a consistent rule. Because of this, bastards who are half-siblings might have different surnames. For example, King Robert I Baratheon's eldest bastard, born in the Vale, is called Mya Stone, while his bastard from the Stormlands (fathered on a noblewoman from the Reach) is called Edric Storm. However, whilst Aegor Rivers was raised at Stone Hedge in the Riverlands, his half-brother Brynden, was also called Rivers, despite having lived at least the first few years of his life with his mother at King's Landing in the Crownlands.
So it would have depended on which parent took custody of Jon.
If it had been Rhaegar, Jon would have likely been a Waters since Rhaegar would have taken him back to the Crownlands.
If it had been Lyanna, Jon would have likely still been a Snow since he would have been brought back to the North.
In the books it depends on the region of the family, but Targaryens had a special name for their bastards, that being Blackfyre, so i suppose Jon would be a Blackfyre since Rhaegar is his father.

 Nothing about this answer, down to the spelling of Jon, is correct. – Ghoti and Chips Aug 28 '17 at 18:15

 Yeah but, to be clear: In the books it depends on the region of the family Wrong, it depends on the region that the child is born or raised, irrespective of the noble parent's domain. Targaryens had a special name for their bastards, that being Blackfyre Wrong, Targaryen bastards had the same naming scheme as other houses' bastards (e.g. Aegor and Brynden Rivers). Blackfyre is unrelated and refers to a chosen name. Jon would be a Blackfyre Wrong, he would be a Sand, being born in Dorne. since Rhaegar is his father Wrong. Rhaegar being a Targaryen wouldn't make him a Blackfyre. – Ghoti and Chips Aug 28 '17 at 18:24

Energistics Transfer Protocol (ETP) Software Development Kit (SDK)
Energistics Transfer Protocol (ETP) Software Development Kit (SDK)
The ETP Software DevKit provides a common foundation and basic infrastructure to simplify and standardize creating applications that transfer WITSML, PRODML and RESQML data via the Energistics Transfer Protocol.

about the devkit
The ETP Specification defines the messages and interfaces that can be used to exchange data between applications that support the EnergyML family of data standards: WITSML, PRODML and RESQML. The messages define the content that is exchanged between applications and the interfaces define the expected behavior in exchanging messages. More information about ETP resources can be found at here.

The ETP DevKit is a .NET library providing a common foundation and the basic infrastructure needed to communicate via the Energistics Transfer Protocol (ETP). The library is written in C# using the .NET Framework version 4.5.2. It is designed to simplify and standardize ETP client and server development by integrating the necessary dependencies and abstracting away the lower level details of communicating via ETP. It builds on the ETP Messages library, which provides .NET definitions for the ETP messages and associated data structures.

The ETP DevKit provides a definition and base implementation of each interface described in the ETP Specification. Each interface implementation has been developed as a protocol handler that can be used out of the box or extended to provide additional functionality. This abstracts away the low level details of sending and receiving messages between clients and servers. Customized processing of messages can be achieved either by registering handlers for the various interface events or by deriving from the library's protocol handlers and overriding the virtual message handling methods.

The aim of the ETP DevKit is to reduce the time it takes to develop and evaluate the latest version of the standards utilizing the Energistics Transfer Protocol and to provide a shared and tested framework for establishing and facilitating communication between applications needing to exchange data.

I wanted to get any ideas/information on how to attack the following performance issue.
Given the following query:
select *
from station_status_history
where station_id = <...>
order by timestamp desc
limit 1;
It will perform rather different for 2 different station_id values:
 - station 1: query will be fast. there are roughly 6000k records for this station id. Latest records are no older than a few minutes ago from now
 - station 2: query will be very slow. there is only 1 record in the table and it is generally quite old (e.g. even up to one year old)
Here are the to query plans for each station:
The fast one:
Limit (cost=0.56..644.44 rows=1 width=134) (actual time=0.105..0.106 rows=1 loops=1)

 Index Cond: (station_id = 17453)
 Buffers: shared hit=15 read=1 dirtied=1 <=========
Total runtime: 0.128 ms
The slow one:
Limit (cost=0.56..644.44 rows=1 width=134) (actual time=5040.417..5040.418 rows=1 loops=1)
 Buffers: shared hit=12804 read=730743 written=1060
 -> Index Scan Backward using station_status_history_pk on station_status_history (cost=0.56.._PHONE_.44 rows=5787 width=134) (actual time=5040.415..5040.415 rows=1 loops=1)
 Index Cond: (station_id = 16799)
 Buffers: shared hit=12804 read=730743 written=1060 <=========
Total runtime: 5040.467 ms
My suspicion was the records's age and its relation with the Buffers information but didn't know how to go about it to fix it

The behaviour you describe is expected with the index you have on (timestamp, station_id, ...). The plan is doing a backwards scan on that index and sometimes it finds the first matching row fast and sometimes it has to go through thousands or million of rows before it find the first matching row.
I suggest you add an index on (station_id, timestamp). The plan will change to do just an index seek on this index (and then a lookup on the table to get the data from other columns). You only need one row and there will be no scan.

Thanks for the quick answer @ypercube !
I did what you suggested (on a test database hence the smaller numbers on the examples below) and whilst I think the performance issue is fixed, I think it is not doing 100% what you imagined: it is indeed using the new index but the steps in the plan are the same ( same Index Scan Backward as opposed to Index seek like you mentioned)
Here is the plan for the slow station without modifications:
Limit (cost=0.43..44.53 rows=1 width=134) (actual time=136.025..136.026 rows=1 loops=1)
 Buffers: shared hit=42639
 -> Index Scan Backward using station_status_history_pk on station_status_history (cost=0.43..248947.57 rows=5646 width=134) (actual time=136.024..136.024 rows=1 loops=1)
 Index Cond: (station_id = 13543)
 Buffers: shared hit=42639
Total runtime: 136.111 ms
and here is the plan with the new index:
CREATE INDEX station_status_history_new_index_test ON station_status_history (station_id, timestamp);
Limit (cost=0.43..4.35 rows=1 width=134) (actual time=0.023..0.023 rows=1 loops=1)
 Buffers: shared hit=4
 -> Index Scan Backward using station_status_history_new_index_test on station_status_history (cost=0.43..22154.13 rows=5649 width=134) (actual time=0.021..0.021 rows=1 loops=1)
 Index Cond: (station_id = 13543)
 Buffers: shared hit=4
Total runtime: 0.071 ms
So yes a lot quicker!
I just wanted to confirm this was what you meant ?
EDIT After reading mustaccio's comment I tried the following index (with desc in the timestamp column) :
CREATE INDEX station_status_history_new_index_test ON station_status_history (station_id, timestamp desc);
and the plan changed slightly, maybe for the better even ?
the plan for the slow station with new index with desc timestamp:
Limit (cost=0.43..4.35 rows=1 width=134) (actual time=0.022..0.023 rows=1 loops=1)
 Buffers: shared hit=4
 -> Index Scan using station_status_history_new_index_test on station_status_history (cost=0.43..22242.15 rows=5672 width=134) (actual time=0.021..0.021 rows=1 loops=1)
 Index Cond: (station_id = 13543)
 Buffers: shared hit=4
Total runtime: 0.061 ms
So now we are no longer using Index Scan Backward but Index Scan instead.
Is that generally better or we only need to look at the final execution times?
Was this the actual plan you were expecting to see @ypercube when you first answered the question ?

 - Yes, indeed. I might had been confused with plans from other DBMS. Index scan backwards looks ok. I think this is generic, if the LIMIT was higher than 1, it would need to scan more than one row. Oct 1, 2021 at 12:31
 - 1
 As for choosing between (station_id, timestamp) and (station_id, timestamp DESC), the difference in efficiency would be negligible. As obvious from the plan, Postgres can do backwards scans. Oct 1, 2021 at 12:34
 - The performance of the above two indexes will differ for different queries, e.g. with ORDER BY station_id, timestamp vs

Land For Good is celebrating 20 years of helping farmers thrive, connecting people and land, and making more land available for farming across New England. We thank the many partners who have collaborated on research projects, new tools and resources, or workshopping policy ideas. We recognize the landowners who've bravely faced questions on how to keep land in agriculture and the farmers who've explored new opportunities with hope and determination.
We're proud to be working along with all of you at the forefront of changing the way land is accessed, held and transferred to future farmers across the country.
In 2004, Land For Good (LFG) was formed to help older farmers with farm succession. The organization's scope soon widened to include farm seekers who were eager to access farmland, and owners and managers of agricultural land. These audiences needed the resources and support that LFG grew to provide. We hired Field Agent staff on the ground in each New England state (most are or have been farmers themselves) to offer educational programs and direct support within a specific geographic area. We offered one of the first farm link programs in the country. We have developed dozens of guidebooks, fact sheets, and interactive online tools. We have served in working groups across New England to advance farmer-support programs and policies. And we've brought together diverse groups of service providers for training and peer-sharing. Organizations across the country have received training or technical assistance from LFG staff.
During the COVID pandemic, we pivoted to online delivery methods for educational content, providing greater access and a wider reach for farmers and landowners. Additionally, LFG identified social justice and racial equity as a strategic priority in 2019. We conducted assessments and training, in collaboration with consultants. In 2023 LFG embarked on a formal equity-infused planning process to refine the organization's strategic approach.
Informed by our work on the ground, we continue to share lessons learned about systemic barriers to farmland access, and suggest policy and service improvements that address the changes needed to shift power and farmland access more broadly. We continue to provide much needed services, public education, input on public policy, and a fresh examination of agricultural land tenure issues and challenges on a regional and national scale.
Save the date! Celebrate this 20 year milestone with good company and good food – and a special tribute – on September 25, 2024 at Smolak Farms in North Andover, Massachusetts. Tickets will go on sale this summer! As one of LFG's first farm clients, Smolak Farms is the perfect host for this anniversary celebration.

This requires that the variable expr be in-scope when the quasiquote is encountered, and that it is bound to a value of type Language.Haskell.TH.Quote.QuasiQuoter, which contains an expression quoter and a pattern quoter. Note that expr must obey the same stage restrictions as Template Haskell; in particular, it may not be defined in the same module where it is used as a quasiquoter, but must be imported.
Our expression and pattern quoters are quoteExprExp and quoteExprPat, respectively, so our quasiquoter expr is written as follows:
quoteExprExp :: String -> TH.ExpQ
quoteExprPat :: String -> TH.PatQ

expr :: QuasiQuoter
expr = QuasiQuoter quoteExprExp quoteExprPat
Our quasiquoters re-use the parser we wrote in the previous section, parseExpr, and make use of the generic functions dataToExpQ and dataToPatQ (described in the Haskell Workshop paper). These functions, from the Language.Haskell.TH.Quote package, take a Haskell value and reflect it back into the language as Template Haskell abstract syntax. The catch is that we don't want to handle all values generically: antiquoted values must be handled specially. Consider the AntiExpr constructor; we don't want this constructor to be mapped to Template Haskell abstract syntax for the AntiExpr constructor, but to abstract syntax for the Haskell variable named by the constructor's argument. The extQ combinator allows us to do this nicely by defining a function antiExprExp that handles antiquotations.
quoteExprExp s = do loc <- TH.location
 let pos = (TH.loc_filename loc,
 fst (TH.loc_start loc),
 snd (TH.loc_start loc))
 expr <- parseExpr pos s
 dataToExpQ (const Nothing 'extQ' antiExprExp) expr

antiExprExp :: Expr -> Maybe (TH.Q TH.Exp)
antiExprExp (AntiIntExpr v) = Just $ TH.appE (TH.conE (TH.mkName "IntExpr"))
 (TH.varE (TH.mkName v))
antiExprExp (AntiExpr v) = Just $ TH.varE (TH.mkName v)
antiExprExp _ = Nothing
The corresponding code for patterns is:
quoteExprPat s = do loc <- TH.location
 let pos = (TH.loc_filename loc,
 fst (TH.loc_start loc),
 snd (TH.loc_start loc))
 expr <- parseExpr pos s
 dataToPatQ (const Nothing 'extQ' antiExprPat) expr

antiExprPat :: Expr -> Maybe (TH.Q TH.Pat)
antiExprPat (AntiIntExpr v) = Just $ TH.conP (TH.mkName "IntExpr")
 [TH.varP (TH.mkName v)]
antiExprPat (AntiExpr v) = Just $ TH.varP (TH.mkName v)
antiExprPat _ = Nothing
4 Examples
We can now try out a few examples by invoking ghci as follows: ghci -XQuasiQuotes Expr/Quote
> [expr|1 + 3 + 5|]
 BinopExpr AddOp (BinopExpr AddOp (IntExpr 1) (IntExpr 3)) (IntExpr 5)
> eval [expr|1 + 3 + 5|]
 9
Taking advantage of our quasiquoter, we can re-write our evaluator so it uses concrete syntax:
eval' :: Expr -> Integer
eval' [expr|$int:x|] = x
eval' [expr|$x + $y|] = eval' x + eval' y
eval' [expr|$x - $y|] = eval' x - eval' y
eval' [expr|$x * $y|] = eval' x * eval' y
eval' [expr|$x / $y|] = eval' x 'div' eval' y
Let's make sure it works as advertised:
> eval [expr|1 + 2 + 3|] == eval' [expr|1 + 2 + 3|]
 True
> eval [expr|1 + 3 * 5|] == eval' [expr|1 + 3 * 5|]
 True

Umm al Quwain: Oldest Pearl in the World
The oldest pearl in the world is found in the United Arab Emirates, according to AOL news/Huffpost this morning:
French researchers are flashing their pearly whites after a historic discovery: what's believed to be the oldest pearl in the history of the human world.
Discovered in a grave, the Umm al Quwain pearl — named for the location in the United Arab Emirates where it was found — has been carbon-dated back to the 5500 B.C., during the Neolithic Period, which makes it more than 7,500 years old, Press Trust of India reports. Previously, the oldest known pearl was just over 5,000 years old.
According to Discovery News, the pearl is 0.07 inches in diameter and remains fully intact. Pearls buried with the deceased were typically either half-drilled for a man or fully drilled for a woman, though unpierced pearls were often placed on the deceased's upper lip.
The discovery provides insight into the origins of pearl oyster hunting, suggesting the practice began in Arabia and not in Japan, as researchers originally thought.
The Neolithic period, also known as the New Stone Age, was marked by the change in humans from hunter-gatherers to farmers. The recent discovery has proved that while dangerous, pearl oyster diving became an important part of society in ancient Arab cultures, according to Indian Express.
Discovery News notes that 101 Neolithic pearls have been unearthed from large pearl oysters over the years.

Resolved: about the queries
Select count(salary)
 from salaries
 where salary >= 100000
is similar to
Select count(*)
 from salaries
 where salary >= 100000
why the 2nd query also counts the records with NULL values when the condition WHERE salary>100000 is already applied? is this how the syntax works ?
id salary
1 90000
2 110000
3 NULL
4 120000
5 95000
considering this table above
the first query would give 3 as a result
and the 2nd query would give 4 as a result.
But why?

Hi Agrim!
Thanks for reaching out.
Actually, both of the queries you provided will give the same result under normal circumstances because the WHERE clause excludes any rows where salary is NULL before the counting occurs. NULL values do not meet any relational operator conditions (like >=, <, =, etc.), so they are inherently excluded by the WHERE clause.
For the table you provided, both queries will count only the rows where salary is at least 100,000:
- Row 2: salary = 110000
- Row 4: salary = 120000
Therefore, both queries should return 2, not 3 or 4, as NULL values and any salaries below 100,000 are excluded by the WHERE condition.
Hope this helps.
Best,
Tsvetelin

With the release of CyaSSL 1.8.0, users are now able to create CA signed x509 v3 certificates. Certificate generation is turned off by default, but may be turned on during the ./configure process with the following option or by defining CYASSL_CERT_GEN in Windows or non-standard environments:
Currently CyaSSL only supports the MD5_WITH_RSA signature algorithm type (which is by far the most common) and the creation of self signed certificates. The next release will allow other signers and other signature types. To create a self-signed certificate the general steps taken by the user include:
1. Create the Cert structure
2. Initialize the Cert structure
3. Complete the information in the CertName structure
4. Generate the self-signed certificate using any valid RsaKey and RNG.
The result of the above steps will be a DER formatted certificate which may also be converted into a PEM formatted certificate if desired. For more information on how CyaSSL generates RSA keys, please see the CyaSSL Extensions Reference, Section X. For complete details of the above steps to create a self-signed certificate and how you can create a CA signed certificate, see the CyaSSL Extensions Reference, Section XI.

The electrical and optical characteristics of a 370 nm AlGaN light-emitting diode based on a microring geometry is presented. By structuring the light emission area into an interconnected array of microscale rings, current spreading in the n-type cladding layers is improved. A reduction of differential series resistance is observed, and the device saturates at a higher current as the carriers are injected efficiently and uniformly across the junction areas. As a result, optical output power from the microring light-emitting diode is improved compared to a conventional device of broad area geometry.

Listed on the Canadian Register:
Statement of Significance
Description of Historic Place
St. John's Anglican Church National Historic Site of Canada is a large, white wooden Carpenter Gothic style church in the heart of Lunenburg, Nova Scotia. Regarded as an important symbol of the town, it has continually evolved over a period of some two hundred and fifty years and, most recently, was rehabilitated after a disastrous fire in 2001. Official recognition refers to the church on its legal lot.
St. John's Anglican Church was designated a national historic site of Canada in 1994 because of:
- its contribution to the establishment of British authority and the Church of England in 18th-century Nova Scotia, through the continuity of its role within the Anglican church and through the evolutionary nature of its building;
- it is a noteworthy illustration of the Carpenter Gothic style which makes it a distinctive example of the Gothic Revival style in Canadian church architecture;
- the building is an important anchor, symbolically and physically, in the town plan of Lunenburg.
The heritage value of this site resides in its associations with the history of Nova Scotia and the town of Lunenburg, and in its architecture. These values are expressed in the setting and location of the church and those elements of its design, as well as the physical elements that survived the fire of 2001. St. John's Anglican Church was originally constructed _PHONE_, enlarged in 1840 and through the 1870s, and again in 1889. After a disastrous fire in 2001, the structure was rebuilt from the surviving ruins.
Sources: Historic Sites and Monuments Board of Canada, Minute, June 1994; Assessment of Surviving Values, June 2001.
Key elements contributing to the heritage character of this site include:
- its location on one of the four town blocks set aside for public use;
- the open landscaping with lawns, paths, benches and a memorial to the first outdoor religious service held on site;
- the church as the visual anchor in its immediate setting, ensured by the restrained scale of surrounding buildings;
- use of Carpenter Gothic style design elements, such as basilica plan with side aisles and chancel under a steep gable roof, entry façade with a rose window and twin towers, Gothic Revival detailing including pinnacles, turrets, false buttresses, pointed arches, drip mouldings, and wood shingle cladding;
- the foundations and ground floor traces of various construction phases;
- surviving pre-2001 wooden structural elements, including portions of walls and support elements;
- remains of the pre-2001 façade and central tower, moulded and carved wooden decorative elements, and interior columns;
- remains of pre-2001 decorative treatments including wall and ceiling paintings, wall stencilling, marbleizing on columns, and stained glass windows;
- surviving pre-2001 exterior decorative elements and cladding;
- surviving pre-2001 church furnishings including the altar, pulpit, pews on the ground floor and balcony, and brassware;
- surviving memorial elements such as the stained glass, stone, brass and wooden plaques.

A Ritual for the Planet by Candlelight for Earth Hour
Every year after the Spring Equinox is Earth Hour.
Earth Hour is an annual event when people are encouraged to turn off all non-essential electric lights for an hour as a symbol for their commitment to the planet. It usually takes place from 8.30pm to 9.30pm on a Saturday close to the Spring Equinox at local times all over the world and is a grassroots event, organised by the World Wildlife Fund.
The idea is that instead of using electricity, you do things by candlelight. Activities often include things like dining by candlelight, playing games or having a candlelit procession. However, you could try some candle magic while the electric lights are off.
Here is a ritual for Earth Hour designed to be done by candlelight – although you could do it as a Spring Equinox rite instead if you preferred. The ritual includes casting a circle by candlelight, scrying (or divination) for insight into what you could do to help the environment, and then making a dedication of actions you intend to make in the future.
You will need:
A candle lantern
Plenty of candles to light your space
A bowl or wine glass full of water for scrying
Paper and pens or pencils for everyone present
Some cake and wine (or fruit juice) to share
Optional: A dark and light candle to represent balance.
To start with, light enough candles to see by and put the rest of the things in the middle of your space – perhaps on a small table. Turn off your electric lights and begin your ritual by casting a circle.
How to cast the circle
Casting a circle is done at the beginning of rituals to create a safe and sacred space to contain the magical energy raised and keep out unwanted influences. Here is a simple way to cast a circle using just a candle in a lantern. All you need to do is walk clockwise in a circle around the edge of your space with the lit candle in the lantern. As you do so, try to visualise a circle of light surrounding the area. You can say: "By the light of this candle I cast this circle to be a safe and sacred space within which to honour Planet Earth for Earth Hour."
When you have done that, put the lantern down at the north of the circle you have cast and, if you want, also arrange other candles around the edge of the circle. It does look lovely and helps define your space.
The word 'scry' means to look, and is another term for divination or fortune telling, often using a crystal ball or a bowl of water. It is best done either by moonlight or candlelight.
Place your bowl or glass of water somewhere that everyone present can see it. Everyone should take a few deep breaths to relax and then concentrate on
the question they wish answered. For this Earth Hour rite, the question is: "What should I do, and what should I stop doing, to help the planet?"
Then all present should peer into the bowl of water and watch to see if any shapes or images appear. You probably need to give everyone at least 20 minutes for this, because it can take some time to get answers. Don't talk while you are scrying, just concentrate on looking at the water. The answers might come to you as images, shapes or shadows in the water, but they might simply be thoughts that come into your mind. Scrying can take a bit of practice, so don't worry too much if you don't seem to get anything. It can help to half-close your eyes as you scry.
Dedication of actions
Now it is time to write down the answers you got from the scrying, or to write down other thoughts about what you are going to do to help the environment.
Give everyone pens or pencils and paper for them to make two lists. One list is for actions they are going to take, the other is for things they are going to do less of. If you like you can have one dark candle and one light candle lit on the table to represent the balance of the two lists, but that's optional.
For example, you might say you will start growing your own vegetables, but waste less food; or you might say you will recycle more, but also aim to buy fewer products that are overpackaged. You might even choose to set up a donation to the World Wildlife Fund, but eat less factory-farmed produce.
After the ritual, everyone should put their lists somewhere they will see them to be reminded of their good intentions.
Cakes and wine
It is traditional to end rituals by sharing cakes and wine (or fruit juice for drivers and those who don't drink). Raise a toast to Planet Earth and make a promise to keep your intentions. Save a little of the food and drink as an offering the Earth– to be put outside after the ritual.
At the end of the rite, walk anticlockwise around the circle with the candle lantern and say: "The circle is open, the rite is done." Then snuff out the candle.
Timing an hour by candlelight
This is optional, but if you want to measure the hour by candlight, all you need to do is get a household candle or dinner candle that burns for a stated length of time. Just put a ruler along the edge of the candle, measure the length that will burn in an hour and stick a pin in at that point. Then light the candle at the start of Earth Hour and us it to measure how the time is progressing.
Other candle spells
My book Pagan Portals - Candle Magic: A Witch's Guide to Spells and Rituals details of lots of other spells you could try by candlelight for Earth Hour - or any other time.

Urinating Swimmers Blamed for Dead Fish
Sign Up for Free eNewsletter ››
By Myles Collier, Christian Post Contributor
May 15, 2012|3:10 pm
German officials have banned locals from entering a lake in northern Germany while they determine if reports of swimmers urinating in the lake have caused the lakes fish to die.
Eichbaum Lake is currently being studied by researchers who believe that a large amount of human urine is responsible for an algae bloom that killed off an estimated 500 fish.
"Swimmers who urinate in the lake are introducing a lot of phosphate" that can lead to algae blooms, a spokesman for the Hamburger Angling Association told Bild newspaper.
"We're calculating half a liter of urine per swimmer per day," he said.
Swimmers are currently banned from the lake due to the high levels of algae, but the city's Urban Development and Environment Authority (BSU) is trying to re-open the lake to swimmers by the time the summer season starts.
In order to identify exactly what is causing the fish to die off, the BSU is requesting the help of a local university to test the urinating hypothesis.

Local media reports have stated that it was not just the "urinators" that were responsible, but the combination of natural causes and a frozen lake.
In the winter time the lake freezes over and is used by many for ice skating. The ice skating may actually disrupt the fish while they are hibernating, leading to their deaths.
"The ice-skaters make a noise that wakes the fish out of hibernation," BSU spokeswoman Kerstin Graupner told the Local. "Then they can't breathe and freeze. That's a very common phenomenon."
She added that their bodies are only now being found.
Urine, however, is being considered a real threat to the health of the lakes ecosystem. The blog i09 explained that phosphates found in human urine work in a similar fashion as fertilizer which can lead to explosive algae growth.
When levels of algae increase the plants absorb all of the oxygen in the water, which then leads to the fish suffocating.

During the gravel packing and fracturing processes in deviated wells the flows can follow complicated three-dimensional paths in the treating string. In this paper we present the formulation of a three-dimensional numerical model of fluid and solids transport for evaluation and design of these completion events. The simulator tracks the slurry flow from the surface, throughout the wellbore, and into the perforations. It treats fluid return and loss into the formation. The model simulates fluid displacement, gravel settling, dune formation, bridging, fluid flow through packed solids and flow into and out of screens.
We present validation results against laboratory and field data for various fluids, deviations, pumping rates, and solids loading.

The Quiz
Just the things you ought to know.
With this year's Game approaching, The Indy wants readers as informed as possible about the oldest game in college football. And with The Game being played almost every year since 1875, it is difficult to keep track of all the history, tomfoolery, and revelry that surround the rivalry. So, without further ado, here is a quiz to both test your knowledge and fill in what you may have missed. The Harvard Independent presents nine questions for nine straight wins.
1) Who won last year's Game?
 1. Harvard
 2. Yale
 3. MIT Pranksters
 4. The Harvard Band
2) How about The Game before that?
 1. Harvard
 2. Yale
 3. The Tailgaters
 4. Toads
3) Okay, let's get more difficult. Who won The Game in 1968?
 1. Harvard
 2. Yale
 3. Both
 4. Neither
4) Who won the very first Game?
 1. Harvard
 2. Yale
 3. Collegiate School
 4. None of the Above
5) What was the score of the first Game?
 1. 12-7
 2. 4-0
 3. 37-12
 4. 29-29
6) Who scored Harvard's only touchdown in their 21-7 loss in 1955?
 1. a) John F. Kennedy
 2. b) Edward Kennedy
 3. c) Someone who isn't a Kennedy
 4. d) Why would we ask if it weren't a Kennedy?
7) What is the name of the Yale mascot?
 1. Ugly Dan
 2. Handsome Dan
 3. Handsome Dan XVII
 4. Handsome Dan XXX
8) Who did Lee Corso pick in 2014?
 1. Harvard
 2. Yale
 3. Kirk Herbstreit
 4. Handsome Dan XVII
9) Who is going to win in 2015?
 1. Harvard
 2. Harvard
 3. Harvard
 4. Harvard
1) Harvard won last year 31-24, which was their eight straight victory. Notably, it was also the very first time The Game was featured as the Game of the Week for College Gameday, Theoretically, if College Gameday had existed in the late 1890s and early 1900s, Harvard-Yale would have been the Game of the Week more often. Alas
2) Harvard won 34-7 in the Yale Bowl. This was just to rub it in Yale's face.
3) Trick question, the answer in (d) Neither. This game is one of the most famous, with Harvard rallying from a 29-13 deficit with two minutes remaining to tie the game. Famously, another newspaper with either somewhat witty or very dumb copy editors published the headliner: "Harvard Beats Yale 29-29."
4) Harvard won the very first Game, naturally. The answer (c) is actually Yale's original name, when it was simply a small school taught out of some guy's house.
5) The first game ended with Harvard winning 4 goals and 2 touchdowns to 0. Back then, apparently, field goals and touchdowns were kept separately, with the latter not even counting for points. What an odd game.
6) Edward "Ted" Kennedy scored our lone touchdown. The Kennedys always did find a way to score it seems.
7) The correct answer is in fact (c) Handsome Dan XVII. He has been the mascot since 2007, and Yale will replace him with Handsome Dan XVIII just like they did to Handsome Dan XVI. Cruel, cruel school.
8) He picked Yale and was wrong. It is commonly assumed that he picked the inferior school because they have a mascot and we have a color, thus not allowing him to put on our "mascot" head. He could have painted his face.
9) Go Harvard. Roll Crimson.
Sean Frazzette '16 ([email protected]) has no doubts about this year.

In the theory of partial differential equations, elliptic operators are differential operators that generalize the Laplace operator. They are defined by the condition that the coefficients of the highest-order derivatives be positive, which implies the key property that the principal symbol is invertible, or equivalently that there are no real characteristic directions.
Elliptic operators are typical of potential theory, and they appear frequently in electrostatics and continuum mechanics. Elliptic regularity implies that their solutions tend to be smooth functions (if the coefficients in the operator are smooth). Steady-state solutions to hyperbolic and parabolic equations generally solve elliptic equations.
A linear differential operator L of order m on a domain in Rd given by
is called elliptic if for every x in and every non-zero in Rd,
In many applications, this condition is not strong enough, and instead a uniform ellipticity condition may be imposed for operators of degree m = 2k:
where C is a positive constant. Note that ellipticity only depends on the highest-order terms.

is elliptic if its first-order Taylor expansion with respect to u and its derivatives about any point is a linear elliptic operator.
- Example 1
- The negative of the Laplacian in Rd given by
- is a uniformly elliptic operator. The Laplace operator occurs frequently in electrostatics. If ρ is the charge density within some region Ω, the potential Φ must satisfy the equation
- Example 2
- Given a matrix-valued function A(x) which is symmetric and positive definite for every x, having components aij, the operator
- is elliptic. This is the most general form of a second-order divergence form linear elliptic differential operator. The Laplace operator is obtained by taking A = I. These operators also occur in electrostatics in polarized media.
- Example 3
- For p a non-negative number, the p-Laplacian is a nonlinear elliptic operator defined by
- A similar nonlinear operator occurs in glacier mechanics. The Cauchy stress tensor of ice, according to Glen's flow law, is given by
- for some constant B. The velocity of an ice sheet in steady state will then solve the nonlinear elliptic system
- where ρ is the ice density, g is the gravitational acceleration vector, p is the pressure and Q is a forcing term.
Elliptic regularity theorem
Let L be an elliptic operator of order 2k with coefficients having 2k continuous derivatives. The Dirichlet problem for L is to find a function u, given a function f and some appropriate boundary values, such that Lu = f and such that u has the appropriate boundary values and normal derivatives. The existence theory for elliptic operators, using Gårding's inequality and the Lax–Milgram lemma, only guarantees that a weak solution u exists in the Sobolev space Hk.
This situation is ultimately unsatisfactory, as the weak solution u might not have enough derivatives for the expression Lu to even make sense.
The elliptic regularity theorem guarantees that, provided f is square-integrable, u will in fact have 2k square-integrable weak derivatives. In particular, if f is infinitely-often differentiable, then so is u.
Any differential operator exhibiting this property is called a hypoelliptic operator; thus, every elliptic operator is hypoelliptic. The property also means that every fundamental solution of an elliptic operator is infinitely differentiable in any neighborhood not containing 0.
As an application, suppose a function satisfies the Cauchy-Riemann equations. Since the Cauchy-Riemann equations form an elliptic operator, it follows that is smooth.
General definition
Let be a (possibly nonlinear) differential operator between vector bundles of any rank. Take its principal symbol with respect to a one-form. (Basically, what we are doing is replacing the highest order covariant derivatives by vector fields.)
We say is weakly elliptic if is a linear isomorphism for every non-zero.
We say is (uniformly) strongly elliptic if for some constant,
for all and all. It is important to note that the definition of ellipticity in the previous part of the article is strong ellipticity. Here is an inner product. Notice that the are covector fields or one-forms, but the are elements of the vector bundle upon which acts.
The quintessential example of a (strongly) elliptic operator is the Laplacian (or its negative, depending upon convention). It is not hard to see that needs to be of even order for strong ellipticity to even be an option. Otherwise, just consider plugging in both and its negative. On the other hand, a weakly elliptic first-order operator, such as the Dirac operator can square to become a strongly elliptic operator, such as the Laplacian. The composition of weakly elliptic operators is weakly elliptic.
Weak ellipticity is nevertheless strong enough for the Fredholm alternative, Schauder estimates, and the Atiyah–Singer index theorem. On the other hand, we need strong ellipticity for the maximum principle, and to guarantee that the eigenvalues are discrete, and their only limit point is infinity.

text: Using data from a survey of 250 farmers and applying different impact assessment methods, this paper provides an ex-post impact assessment of the Soil Remediation Research Project undertaken by IWMI in Northeast Thailand during 2002-2005. This project demonstrated and promoted the application of clay technology as a quick and costeffective means of improving the fertility and water holding capacity of sandy soils. With the empirically estimated average impacts of this technology, and the clay using area observed in the sample (176 hectares [ha]) and that estimated for the region (5,600 ha), the overall impact and economic viability of this project are evaluated during 2002-2008 for both the sample and also at regional level. Recognizing the roles of partners and others, the share of benefits attributed to IWMI are only 50 and 10% for the sample and regional level evaluations, respectively. From an exclusive IWMI perspective, the project has a net present value (NPV) of US$0.41 million involving an internal rate of return (IRR) of 36% and a benefit-cost ratio (BCR) of 2.44 in the context of the sample. But, in the larger context of the region, it has a NPV of US$21 million involving an IRR of 267% and a BCR of 75. Since impacts cover only direct income benefits, and since their evaluation involves conservative assumptions on benefit calculation and attribution, these estimates represent only the lower bounds of the true size of the project's impact. Despite an apparent soil focus, the evaluated impacts also equally capture the effect on yields of an improved soil water holding capacity.

city, Pulaski county, central Arkansas, U.S., on the Arkansas River opposite Little Rock. It was settled in 1812 as De Cantillon, became Huntersville in 1853, and was later renamed Argenta for the Hotel Argenta, built there in the late 1850s. The community developed after the arrival of the Memphis and Little Rock Railroad in 1853 and later became the site of the freight classification yards and maintenance shops of the Missouri Pacific (now merged with Union Pacific) Railroad. Annexed by the city of Little Rock in 1890, Argenta was separately incorporated as a town in 1901 and renamed North Little Rock. It became a city in 1904 and absorbed the town of Levy to the north in 1946.

Grape Hyacinth Leaves Are Turning Red
I have bought a small pot with 7 Grape Hyacinth leaves in it and have had them bloom nicely in my house for a while when the lower flowers started wilting and the leaves started turning red and also look like they are wilting. What is happening with the bulbs? Are they pressed together too closely? Or am I watering wrongly? Would it help if I replanted them into different pots? Thank you in advance for your time! Regards, Tanya
Grape hyacinths are a spring ephemeral which means they go dormant soon after blooming. It is true that the flower business often packs bulbs in closer than one would plant in the garden but this isn't a problem for grape hyacinths. Plants must be in pots with drainage holes or you risk rotting the bulbs/roots. Water when the top inch of soil is dry - poke your finger in the soil. Overwatering and under watering create similar wilting in leaves. If they finished blooming a couple of weeks ago, they are probably going dormant. Otherwise consider using a bigger pot with standard potting mix. Here is a helpful article. Note that if you plant to keep these indoors, you'll have to create a cold treatment to trigger another bloom.

Koala habitat and occupancy mapping program
We completed a 3-year program that mapped koala habitat and occupancy in NSW native forests to inform new identification methods in native forestry areas.
About the program
The program aimed to provide a clear understanding of koala habitat identification and management needs in native forestry areas on public and private land in NSW.
The program comprised 3 core projects:
- a baseline map of koala occupancy to provide a more accurate picture of where koalas are located across NSW
- a pilot project trialling three different mapping approaches to assess their suitability for managing koalas in state forests
- a predictive koala habitat model which uses a range of environmental variables to produce a map of koala habitat on the north coast
The program was funded by a Waste and Environment Levy (WELE) grant, administered by the NSW Environmental Trust.
The results of the koala mapping program have been used to inform the development of improved approaches to protecting koalas and their habitat during forestry operations. This has included new koala identification and protection requirements in the Coastal Integrated Forestry Operations Approvals (IFOA).
The Coastal IFOA ensures that rules for managing koala habitat are modern, fit-for-purpose and that protections are in place to manage the impacts of logging on important koala habitat across the landscape
The Coastal IFOA has moved away from record-triggered approaches to koala protection, which has been shown to have limitations, and instead identifies and protects places in the landscape where koalas are more likely to occur.
This approach is a more comprehensive, adequate and transparent way of protecting important koala habitat. It will mean that habitat will be identified and protected, irrespective of koala occupancy.

The calculation of ballast plan in load-out operations is generally performed assuming a rigid barge. This assumption may not be reliable since in reality the barge is flexible. Having incorrect ballast plan may lead to overstressing of the loaded-out structure. We present a method of finding a more accurate ballast plan, taking into account the flexibility of the barge. This method makes use of a multi-objective evolutionary algorithm to find the optimum ballast arrangement at every load-out stage. We model the load-out configuration as a beam on elastic foundation, loaded with distributed trapezoidal loading representing the load from the structure. Minimizing deflection and curvature of the beam, as well as maximizing the ballast transfer efficiency between the load-out stages are chosen as the objectives of the algorithm. It is shown that the proposed method is better than the conventional rigid barge method in terms of minimizing the deflection and curvature as well as maximizing the ballast transfer efficiency.

How to use IP Filters to restrict student access to tests
In this article, you'll learn how to use the IP Filter option on tests to restrict test access to students who are on computers at a specific location.
An Internet Protocol (IP) address is a number assigned to an Internet-connected device. It serves to identify the device and give the device an "address". Because devices are generally connected to networks in a particular location (e.g. your college campus, your home office, the local coffee shop, etc.) IP addresses can be used to identify where a device is located.
IP Filtering for tests works as follows:
 1. You specify that only devices from certain IP addresses may access the test.
 2. When students go to take the test from the correct IP address, they can access the test.
 3. If they go to take the test from the wrong IP address, they are locked out of the test. Here's what they'll see when that happens.
The typical use for IP Filtering is to ensure that only students in a particular location (perhaps surveyed by a proctor) can access a test. You should not use this tool in online-only courses where your students are located all over the place—it'd be a tremendous hassle keeping track of all the IP addresses you'd need.
When adding a new test assignment, you can add an IP filter restriction.
 1. Follow the instructions for setting up a test assignment.
 2. Under Restrictions, check next to Filter IP addresses.
 3. Enter the IP address(es) from which you wish to permit access to this test. Consult with your school's IT department if you need help determining what to enter in these fields.
 4. When you're done, click Save.

+1 for the remark :-) – Kevin H. Lin Oct 19 '10 at 6:47
If I understand things right, the Hilbert scheme of points in $\mathbb{A}^2$ is hyperkahler manifold and the $n^\textrm{th}$ Calogero-Moser $CM_n$ space can be obtained by deforming the complex structure. The disjoint union of the $CM_n$ parametrizes isomorphism classes of (right) ideals in the first Weyl algebra (polynomial differential operators in 1 variable). This classification is related to Hyugen's principle in differential equations.

One context in which Hilbert schemes provide a useful conceptual picture is in the Fourier expansion of partition functions that are associated to certain Siegel modular forms of genus 2.

Phenolic Content and Radical Scavenging Capacity of Kaffir Lime Fruit Peel Extracts Obtained by Pressurized Hot Water Extraction
The effects of the pressurized hot water extraction (PHWE) parameters (extraction temperature: 100, 150 and 200°C and extraction time: 5, 10 and 15 min) on the total phenolic content and DPPH radical scavenging capacity of the kaffir lime (<I>Citrus hystrix</I>) fruit peel extracts were investigated. Both indices increased as the extraction temperature increased. The extraction time only slightly affected the values. This study also demonstrated that the PHWE produced extracts with a higher phenolic content and radical scavenging capacity than that obtained by a conventional extraction method (water and 60% methanol at 50°C, 1 h).

text: Short hydraulic lines operate mainly in the conditions of nonuniform fluid flow. The presence of grids, blades and other structures in hydraulic lines leads to a sharp change in the flow characteristics and to additional energy losses during the flow. Despite the extensive use of grids, there is insufficient information on the throughput of channels. In this article, flat plastic perforated grids of different degrees of permeability, installed at the outlet of the pipeline, have been investigated. The resistance coefficients of the grids have been determined experimentally. It has been demonstrated that the two methods for determining the resistance coefficient (by flow and by differential pressure on the grids) are identical. The influence of the grids on the capacity of the pipeline has been established. The dependence of the relative flow rate in the pipe on the surface porosity of the grids has been obtained. An alternative transition from the resistance coefficients to the filtration coefficients and permeability of the pipeline with grids has been proposed.

Obviously the German soldiers might notice a tree where there had not been one before. That's why the British Empire's Royal Engineers built fake trees to resemble specific trees in no man's land. During the night, they'd cut down the original and replace it with the fake:
To develop the O.P. Tree, Royal Engineers representatives selected, measured, and photographed the original tree, in situ, extensively. The ideal tree was dead; often it was bomb blasted. The photographs and sketches were brought back to the workshop, where artists constructed an artificial tree of hollow steel cylinders, but containing an internal scaffolding for reinforcement, to allow a sniper or observer to ascend within the structure. Then, under the cover of night, the team cut down the authentic tree and dug a hole in the place of its roots, in which they placed the O.P. Tree. When the sun rose over the field, what looked like a tree was a tree no longer; rather, it was an exquisitely crafted hunting blind, maximizing personal concealment and observational capacity simultaneously.

Saving Current Values with Cascading LOVs
A friend, Monty Latiolais, recently asked an interesting question regarding cascading LOVs:
Say you've got two LOVs...STATES and CITIES. They both default to 'ALL' and 'ALL'. Since CITIES is dependent on STATES, as soon as STATES is changed, CITIES is blanked out. What should happen is that CITIES gets re-evaluated as in the following example... let's say STATES is ALL and CITIES is "Houston". If one then changes STATES to "Texas", CITIES should remain "Houston" as that is a valid value for CITIES.
So basically, is it possible to maintain the selected value of an item if that same value exists in the list of values after refreshing? That's a great question! Thanks to new events in the APEX framework and Dynamic Actions the solution is far easier than it would have been in the past!
Click here to see the demo but continue reading to learn how it all works…
There are a three main events you need to be concerned with when it comes to cascading selects:
 - change
 - apexbeforerefresh
 - apexafterrefresh
The change event is a standard part of JavaScript and the DOM. This event fires when the user manually changes the value of the select list but can also be triggered programmatically via JavaScript. The apexbeforerefresh and apexafterrefresh events are custom events in the APEX framework. They fire just before and just after AJAX requests refresh something on the page. The events work with many items and regions that utilize this technology.
In this example we have two select lists: parent and child. If you change the value of the child select list then the change event will fire and that's it. But if you change the value of the parent select list a lot more happens to the child select. Here are some of the highlights:
 1. The current LOV values are cleared out
 2. The apexbeforerefresh event is triggered
 3. An AJAX request brings back new values. This only happens if
 1. optimize refresh is set to false
 2. optimize refresh is set to true and all parent items are not null
 4. The apexafterrefresh event is triggered
 5. The change event is fired
Now, knowing all of this, how can we utilize the sequence of events to solve the original problem of keeping selected values? The answer lies in creating two dynamic actions.
The first dynamic action will store the current value of the select list so that we can access it later. This will typically happen when the change event fires but it will also happen when the page first loads. Here's how to create the first Dynamic Action:
 1. Right click the child select list and select Creation Dynamic Action.
 2. Select Advanced.
 3. Click Next >.
 4. Enter a name for the first Dynamic Action.
 5. Click Next >.
 6. Set Event to Change.
 7. Click Next >.
 8. Set Action to Execute JavaScript Code.
 9. Set Code to: $(this.triggeringElement).attr('data-last-value', $(this.triggeringElement).val());
 10. Click Next >.
 11. Click Create.
The second Dynamic Action will take advantage of the apexafterrefresh event and access the previously stored value. That value will then be used to look through the new options and if a match is found it will be selected. Here's how to create the second Dynamic Action.
 1. Right click the item (again) and select Create Dynamic Action.
 2. Select Advanced.
 3. Click Next >.
 4. Enter a name for the second Dynamic Action.
 5. Click Next >.
 6. Set Event to After Refresh.
 7. Click Next >.
 8. Set Action to Execute JavaScript Code.
 9. Set Code to: $(this.triggeringElement).children('option[value="' + $(this.triggeringElement).attr('data-last-value') + '"]').attr('selected','selected');
 10. Click Next >.
 11. Click Create.
So two lines of actual code, not bad at all!

Plug-in Update: SkillBuilders Super LOV 1.2
The APEX community has been providing us with lots of great feedback on Super LOV thus far... Keep it coming and we'll keep making it better!
This release includes the following changes:
 1. Integrated buttons in the main input. The buttons are styled using jQuery UI which is consistent with the rest of the plug-in. Also, the "clear" button switches to a confirmation button to help prevent accidental clearing.
 2. Added "Effects Speed" attribute. Many people have had great things to say about the transition effects implemented in Super LOV but some people complained they were too slow for heavy data entry. Now you can adjust the speed to make it faster or set it to instant which essentially disables the effects altogether.
 3. Added "Default Search Column Number" attribute. Currently this will just default the column that is searched when the modal dialog is opened. This attribute will become even more important with the next release – when the item can be made "enterable".
 4. Fixed bug that prevented Cascading LOV attribute from working. The item now "cascades" as it should with both parent and child items.
Future plans include:
 1. Making the input "enterable". This will allow a user to focus in the main input and begin typing. If a single match is retrieved in the LOV, then the hidden item will be updated and the LOV will never open. If multiple matches are found then the LOV will open "pre-filtered" to allow for selection.
 2. Allowing LOV selection to update multiple items/elements. Lot's of people (especially those from Oracle Forms) have been requesting this functionality so we've added it to the list.
To get this plug-in, as well as our other plug-in offerings, visit new "Plug-ins" page at Future plug-in releases, including this one, must be downloaded from that site. Downloads require free registration, but it's a small price to pay for some great functionality. Smile Enjoy!

Analogous to a riverbed channelling water, one can entrench some systemic praxis in organisations through facilitating the design of systemic structures. This includes systemic structures for each organisational function (i.e. systemic process and supply chain design) as well as the coordination of the organisation as a whole through a three-dimensional
However, a riverbed could channel clear or dirty water in the same manner. Likewise, the information within systemically conceived structures could be processed systemically (i.e. synergistically) or conventionally. Put differently, planning and decision-making could involve systemic methodologies to yield synergistic outcomes or not, even if the structures are systemic.
Thus, both structures and praxis need to be systemic, in order to create a systemic learning organisation. As pointed out above, different systems approaches deal with structures and processes somewhat differently and therefore benchmarking can be misleading.
Derived from the Biomatrix meta-systems theory, the Biomatrix Organisational Development Programme is designed to create systemic structures, practices and organisational culture that cohere with each other and are systemic. Organisations applying the programme in its entirety could be subjected to benchmarking. However, since establishing a systemically structured learning organisation can take a couple of years (depending on its size) and different organisations take a different path to get there (due to a modular design depending on the specific needs and realities of the organisation), benchmarking them may also be challenging.

We have evaluated for the first time the Detective Quantum Efficiency of 2 imaging detectors which
are used for Crystallography. Crystallography is the science of determining the arrangement of
atoms within a crystal from the manner in which a beam of usually low energy (8-17.5 keV)
monochromatic X-rays is scattered from the electrons within the crystal. There is a growing
consensus in the scientific world that the Detective Quantum Efficiency (DQE) is the most suitable
parameter for describing the imaging performance of an x-ray imaging device. The DQE describes
the ability of the imaging system to preserve the Signal to Noise Ratio (SNR) on the way from the
radiation field emerging from the very fine and practically monochrome x-ray beam through the
various imaging system components up to the 3-dimensional crystal image.
Normally the DQE of x-ray systems is based on the effective energy of the x-ray beam and the x-ray
dose as measured with a dosimeter. Typical dosimeters are not very accurate at low x-ray energies
which are used in Crystallography. We used an x-ray spectrometer to determine the x-ray photon
Values of DQE at low spatial frequency were at about almost 80 % at 8 keV.


text: In information technology, a repository (pronounced ree-PAHZ-ih-tor-i) is a central place in which an aggregation of data is kept and maintained in an organized way, usually in computer storage. The term is from the Latin repositorium, a vessel or chamber in which things can be placed, and it can mean a place where things are collected. Depending on how the term is used, a repository may be directly accessible to users or may be a place from which specific databases, files, or documents are obtained for further relocation or distribution in a network. A repository may be just the aggregation of data itself into some accessible place of storage or it may also imply some ability to selectively extract data. Related terms are data warehouse and data mining.


Including a Plus Symbol Before Values In Mac Numbers
If you need to include something like a + symbol before positive numbers in cells, you can do it using formulas or using custom cell formatting. Using a custom cell format is more versatile and can be easily reused no matter how complex the calculation.
