In statistics, the midhinge is the average of the first and third quartiles and is thus a measure of location. Equivalently, it is the 25% trimmed mid-range or 25% midsummary; it is an L-estimator.
The midhinge is complemented by the H-spread, or interquartile range, which is the difference of the third and first quartiles and which is a measure of statistical dispersion, in sense that if one knows the midhinge and the interquartile range, one can find the first and third quartiles.
The use of the term "hinge" for the lower or upper quartiles derives from John Tukey's work on exploratory data analysis,[1] and "midhinge" is a fairly modern term dating from around that time. The midhinge is slightly simpler to calculate than the trimean, which originated in the same context and equals the average of the median and the midhinge.

Exploring How We Make Decisions
The Caltech Conte Center for Neuroscience explores how we make decisions in a social setting, an ability that is as ubiquitous in everyday life as it is devastating when dysfunctional in diseases such as autism, schizophrenia or addiction. This center examines four main aspects of social decision making: how basic social rewards are processed in the brain, how these rewards are learned and processed through observation rather than receiving a direct reward, how people process and understand how other individuals feel about rewards, and how the brain regions involved in these experiments are connected on a network level.
How do we process rewards, and how do we learn about rewards in a social setting? Is this done in the same way that we think about how other people think about rewards? This Conte Center for Neuroscience at Caltech addresses these questions using innovative fMRI technology, in order to understand on a very basic level how humans think, learn, and make decisions about rewards.This Conte Center consists of four Projects and three supporting Cores:

GenTask consists of a tool set to graphically define groups of tasks, dependencies among tasks and execute them in the required order in a fully automated manner. A task can be any process that can be executed.
GenTask application was developed fully in Java/XML with an Object Oriented approach. Therefore, it can be run on any platform that supports Java/XML. It contains two related, integrated user interface components for task editing and task execution, respectively.
A "task set" is a set of tasks. When a task set is executed, first the execution path is resolved according to task dependencies and tasks are executed in order. A task set can contain as many tasks as required. Tasks can be given priorities so that the tasks with higher priority are executed before the tasks with lower priority.
The task execution utility runs in a multi-threaded way. As long as the execution path that is determined using task dependencies, allows more than one task to be executed, a new thread is created to execute each simultaneous task. The maximum number of threads can be adjusted using the task execution tool user interface.
When a task set is executed, various information that let the user to monitor the execution (such as status of executed tasks, number of executed tasks, number of tasks yet to be executed, elapsed time and remaining time) is provided in the graphical user interface. The user can also affect the execution by using the graphical facilities provided.
GenTask provides a fully graphical and automated mapping environment, Below is an example screen capture of GenTask:

filme porno gey gratisIn this blog post we'll show you how to create wires and tubes in different ways. We'll start with laying everything on a flat surface, then on an uneven surface and lastly mix things up a bit more.
filme porno gey gratisThese methods and principles will also probably work in other CAD programs, given they have similar tools, of course.
filme porno gey gratis
In this example we'll create an 8 mm outer diameter tube with 1 mm walls which just lays on a flat surface.
First, create a flat surface in the form of a box. Then create a smaller cube with sides large enough to house the cross section of your wire or tube. For our?8 mm tube, we'll just create a 10x10x10 mm cube. This cube is not necessary, but it makes it easy to define a start position and angle. It will also underline an important technique later on. Usually you would have a set place to start and end your wire/tube, but in this case we don't have anything like that.
Then construct an above the large surface with offset equal to your wire/tube radius. In our case this is 4 mm. In addition, create a sketch on one of the sides of the cube where you want your wire/tube to start. Create a circle tangent to the bottom edge as in the screenshot below. This will serve as our sweep profile.
Next, create a spline on the offset plane which starts at the center-point of the proper side of your cube. The shape is not that important, but it will reflect the physical properties of your wire/tube – stiff as a garden hose or soft as boiled spaghetti. Don't worry about the spline being perpendicular on the cube edge yet. What you also can do is to create a straight construction line on the same sketch which starts where the spline starts and goes through the cube. This should be perpendicular to the cube edge/face.
Here comes a neat little trick: create a tangent constraint between your spline and your straight construction line. This way your wire/tube will start in a natural angle relative to what it is attached to. It doesn't matter too much in our example here, but you more often than not want your wire/tube to exit perpendicularly out of a box or whatever. You can also play around with the spline's fit points while the start will stay in the same angle in a natural fashion.
Now comes the fun part! Use the sweep tool and choose the circle on the side of the cube as profile and the spline as patch. Make sure orientation is Perpendicular and that you choose either new body or new component as operation.
To make this thing look less like a smoothly bent steel rod and more like a tube, use the shell tool. Select both ends and specify wall thickness (in our case 1 mm). This will hollow out our steel rod and make it a pipe instead. Alternatively, you can create to circles on the side of the cube (one for the outer diameter and one for the inner) and use the area between them as the sweep profile. This way you don't have to use the shell command.
Give it the clear acrylic appearance and do a quick render. Remember to hide your cube! The result might look something like this:
You can easily change the shape of the tube by moving/adding/removing spline fit points in the sketch. The changes will propagate to the final result. The outer diameter can be changed by altering the circle diameter on the side of the cube. For it to rest on the surface you will need to go change the offset plane offset.

Let's up the complexity a bit. This principle works with any kind of surface, but in this example we will use the sculpting environment to create the uneven surface and go from there.
Start with creating a form. This will take you to the Sculpt workspace. Create a plane with as many faces as you feel like and make it "un-flat" by using the Edit Form tool (drag vertices, edges and/or faces up and/or down). We found our inner artist and created the magnificent wavy surface seen below.
Now we're going to use the handy Thicken tool to create two additional surfaces based on this one: one surface which the center of the tube will follow and another surface which actually will thicken the original surface and create a solid body.
The cool thing about the Thicken tool is that a surface can be thickened either along an axis or along the normal of the surface. We will need to use the Normal direction for the plane that the tube will follow and the No Edge thicken type. Choose a thickness equal to the radius of your tube. In our case this is still 4 mm.
Repeat the operation, only this time reverse the direction, choose either a Sharp or Soft thicken type. The direction parameter and the thickness aren't important (we went with Sharp, Normal and 1 mm).
Create a sketch in the XY plane (if the Z-axis is your vertical axis) and draw your initial tube shape with a spline. Our sketch can be seen below.
Now create a new sketch and choose the Project To Surface tool. This is where the magic happens. Choose the topmost surface as face, the spline as the curve and the vertical axis as projection direction with an Along Vector project type. You can see the result below where the spline follows the chosen surface.
In the first example we used a cube to define the sweep profile. This time we're going to do something different. Construct a plane along path, choose the newly projected curve and drag the plane to one of the ends of the curve like seen below. The curve will always be normal to this plane. Hide the topmost surface (you won't need it anymore).
The rest is easy. Create a tube profile on the newly constructed plane with correct outer radius and use the sweep tool to create the tube.
One issue you might encounter is that the tube may cut into the base surface. This is in our opinion not logical since the target surface for the projection should at any given point be exactly one tube radius away from the base surface. If some of you know why this isn't the case, please leave a note in the comments below.
Luckily, this amount isn't that large. You can see below how much got cut into our base surface. For pure aesthetic purposes, this can be overlooked. We chose to cut away the overlapping part.
Now, put on some silly textures and render. Here's our result.
Up until now, our wires/tubes have followed the surface completely. This makes it look very soft and/or heavy. Smaller wires and tubes are usually quite stiff compared to their weight, and will be floating much more in the air.
Here's an example where we have added a bit more natural stiffness, but it still looks quite soft and heavy.
Here we have used the same approach as the previous example except deviated a bit more from the original surface. What we did here was pretty simple due to the simplicity of the original surface:
- Make a copy of the original body and enlarge it in a normal direction (larger diameter on the cylinder and a bit thicker flat area).
- On the larger body, increase the fillet radius on the sides of the cylinder. This will make the wire/tube float a bit in the air where it's somewhat natural.
- Project to surface and sweep just like before.
Combine what we've talked about up until now with 3D sketching, and you'll have a powerful set of wire/tube making skills. For this to work you need to check the Allow 3D sketching of lines and splines box in the Design preferences. Now you can for instance create a spline on a sketch and manually drag the spline fit points away from the sketch plane, creating a three dimensional spline.
In the render at the very top of this blog post we've used a combination of all these methods and principles. We've combined splines projected to surfaces and 3D splines. Combining these in a smooth way can be a bit tricky sometimes, but give it try! Learning by doing doesn't get old.

The potential violent power of flood waters of the San Antonio River during heavy or extended rainfall prompted the U.S. Army Corps of Engineers to create a huge, straight river channel almost a half a century ago. Although soils near the mission sites have a great deal of clay content, the soil is relatively shallow over limestone bedrock. There are deep alluvial soils in the former river floodplain. Aggressive hydrologic activity can erode isolated sections of banks of rivers, streams and acequias. Man-made cement retaining walls along the river and streams were testament to this hydrologic activity.
The San Antonio River Authority and the U.S. Army Corps of Engineers, in partnership with other organizations, have restored 13 miles of the flood control channel to improve recreation and wildlife habitat with on-going projects. The park will continue to maintain and improve the ecology of park streams. Click on this link to learn more about the river improvement project.

How To Migrate From MOSS 2007 To SharePoint 2010
Are you looking to migrate from MOSS 2007 to SharePoint 2010? Follow our comprehensive guide to ensure a smooth and successful transition.
To migrate from MOSS 2007 to SharePoint 2010, there are several steps that need to be followed:
 1. Take a backup of the content database from MOSS 2007 and set it to read-only.
 2. Restore the content database backup to the SQL Server of SharePoint 2010.
 3. Create a web application in SharePoint 2010.
 4. Attach the MOSS 2007 content databases to SharePoint 2010.
 5. Perform post-migration fixes, such as visual upgrades and testing the migrated sites.
These steps can be performed using methods like database attachment, in-place upgrade, or content migration. It is recommended to thoroughly test and validate the migration in a non-production environment before proceeding with the upgrade.
Steps to Migrate from MOSS 2007 to SharePoint 2010
To successfully migrate from MOSS 2007 to SharePoint 2010, you need to follow a series of important steps. These steps are crucial to ensure a smooth and successful transition and to avoid any potential data loss or disruptions. Let's explore each step in detail:
 1. Backup the content database from your MOSS 2007 environment: Before initiating the migration process, it's essential to take a backup of the content database from your existing MOSS 2007 environment. This backup will serve as a safeguard in case any issues arise during the migration process.
 2. Restore the content database to the SQL Server of SharePoint 2010: Once you have the backup of your content database, restore it to the SQL Server of your SharePoint 2010 environment. This step ensures that all your valuable data and content are transferred to the new platform.
 3. Create a web application in SharePoint 2010: After restoring the content database, the next step is to create a web application in SharePoint 2010. This web application will serve as the foundation for hosting your migrated sites and content.
 4. Attach the MOSS 2007 content databases to SharePoint 2010: Once the web application is set up, you can attach the MOSS 2007 content databases to SharePoint 2010. This process maps the content databases from the old environment to the newly created web application, ensuring seamless access to your data and sites.
 5. Perform post-migration fixes: After attaching the content databases, it's important to carry out post-migration fixes. These fixes may include performing visual upgrades to ensure compatibility with SharePoint 2010's interface, testing the migrated sites for any issues, and making necessary adjustments or configurations.
These steps can be executed using various migration methods such as database attachment, in-place upgrade, or content migration. However, regardless of the method chosen, it is crucial to thoroughly test and validate the migration in a non-production environment before proceeding with the upgrade.
By following these steps and best practices, you can ensure a successful migration from MOSS 2007 to SharePoint 2010, enabling you to leverage the enhanced features and capabilities of the newer version while preserving your valuable data and content.
Step Description
1 Backup MOSS 2007 content database
2 Restore backup to SharePoint 2010 SQL Server
3 Create web application in SharePoint 2010
4 Attach MOSS 2007 content databases to SharePoint 2010
5 Perform post-migration fixes
Migration Methods and Best Practices
There are multiple migration methods you can choose from, but it's important to follow best practices to ensure a successful migration to SharePoint 2010. One method is database attachment, where you take a backup of the content database from MOSS 2007 and restore it to the SQL Server of SharePoint 2010. This allows you to transfer the data and settings from the old version to the new one.
Another option is an in-place upgrade, which involves upgrading the existing MOSS 2007 environment directly to SharePoint 2010. This method is suitable if you want to maintain the same hardware and configurations. However, it is crucial to test and validate the upgrade in a non-production environment to identify and address any compatibility issues before proceeding with the actual migration.
If you prefer a more controlled and granular approach, content migration is a viable method. With this method, you can selectively migrate specific lists, libraries, and sites from MOSS 2007 to SharePoint 2010. This allows you to prioritize and migrate only the necessary content, reducing the risk of migration errors and ensuring a smoother transition.
Regardless of the chosen migration method, it is essential to thoroughly test and validate the migration in a non-production environment. This involves checking the integrity of the migrated content, verifying the functionality and accessibility of sites and workflows, and ensuring that any customizations or third-party solutions work seamlessly in SharePoint 2010.

Competitive neutrality means that state-owned and private businesses compete on a level playing field. This is essential to use resources effectively within the economy and thus achieve growth and development. Therefore the principle of competitive neutrality is gaining wide support around the world. But how to obtain it in practice, is a much more difficult question.
The purpose of this report is to help respond to this question. The report identifies the most important issues that governments need to address in order to achieve competitive neutrality. It is framed around eight building blocks, including choosing the best corporate form, achieving a commercial rate of return, accounting for public service obligations, improving debt neutrality, and making public procurement open and transparent. It provides country examples of how to implement competitive neutrality policies in practice.
The report is not about privatisation. Rather, it aims to provide guidance to policy makers who want to make sure that the presence of the state owned enterprises in the market place does not thwart private entrepreneurs, skew competition or lead to other inefficiencies. Understanding how to avoid unintended economic consequences that may follow from state ownership is particularly important for policy makers that face the challenge to balance the commercial objectives of state owned enterprises with other important policy objectives: A challenge that permeates all levels of government.
The book may be read in conjunction with two publicly available stocktaking papers:

Online Form Available for Federal Premises ID Registration
Producers are encouraged to register for a Premises ID Number for their farm.
As foreign animal diseases such as avian influenza and African swine fever continue to pose threats to the Missouri livestock industry, the Missouri Department of Agriculture encourages producers to create, or tighten, biosecurity plans on their farms. The first step in developing a biosecurity plan is to register for a federal premises ID number (PIN).
A PIN is a unique code permanently assigned to a single physical location. This number can be assigned to locations where animals are born, managed, marketed or exhibited. Allied agricultural operations and non-producer participants can also register for PINs.
PIN registration is administered by the state of Missouri and allows animal health officials to quickly and precisely identify where animals are located in the event of an animal health or food safety emergency. Information gathered through premises registration will be used solely for animal health purposes. This critical data will provide animal health officials with necessary contact information in case of a disease concern.
The Missouri Department of Agriculture is accepting free and voluntary registration of premises in the state.
MDA has created an easy-to-use online federal premises ID registration form. To register for a PIN online, visit _URL_-influenza.php. For those who prefer to register via phone, contact the MDA Animal Health Division at _PHONE_.
Once PIN registration is complete and the premises has been validated by the Animal Health Division, a PIN card will be mailed to the registrant.
If you have already registered for a PIN in the state of Missouri, but have forgotten the number, or need to update information pertaining to the premises, call the Department at _PHONE_.
The Missouri State Fair does not require a PIN to show or exhibit livestock.
For more information about the Missouri Department of Agriculture and its programs, visit the Department online at agriculture.mo.gov.

57. Piano Sound BoardRepairing Cracks
The sound board is a five eighths inch thick wooden board in the back of the piano. On the back of it, it has one inch ribs which stabilize it by running against the grain of the sound board. A sound board is made one of two ways.
The traditional sound board is made of several five eighths thick boards which are glued side by side across the whole inside of the piano. It is the best sounding board, but with age, it can crack.
More recently, sound boards have been made of laminated wood, or glorified plywood. They never crack, but they are slightly dead or muffled. Pay your money and take your chances.
"My sound board is cracked. Is the piano ruined?"
There is a myth still around that a piano is ruined if it has cracks in the sound board. The Steinway people did a test on this. They made a piano with a quarter inch "crack" in it. The cross ribs were tight and normal. When they tested it with Db meters, they found that the piano with a "crack" in it did just as well as a new piano with a perfect sound board.
So, what's the problem? When a piano develops cracks from old age, the cracks can cause buzzes. Also, the crack is much bigger than it would appear. When a crack develops, the spruce of the sound board warps and pulls away from the cross ribs. The effect is to widen the crack as far as acoustics are concerned. The illustrations will help you see what is happening.
While we are here, let's talk about the graphics at the left. You are looking at the front of the sound board area and the lower end of the treble bridge in the lower left an upright from the turn of the century from Leipzig.
The lower graphic shows a crack in the sound board at an angle to the upper left. The end of the bridge mounting board is also hanging in space. This prevents all the sound from transferring from the lowest strings shown into the sound board. The sound will have to travel up the bridge and find a way to the sound board by traveling far. This mutes the sound greatly at times.
The crack and the bridge mounting board separation call for an examination of the bridge to see if the main bridge is also separating. If so, go to Chapter Sever, Section 6-- Bridge Repair for instructions.
The crack here is not badly advanced, but it should be done at once. I also want you to see the severe deterioration of the varnish on the sound board. This sound board was over varnished I think, for the effect looks very think. Try to keep from adding so much varnish when refinishing a sound board. The weight is a real issue, and the cracking could slightly slow down the board.
The object of repairing the sound board is to return the warped sound board to be tight against the rib again.
All you need to buy is a box of 100 No. 10, inch and a quarter wood screws. I suggest Philips head. Also, if you don't have one, get a counter sinking bit for wood which will fit your drill motor.
If you are working on an upright, you will have to get it well away from the wall so that you can work behind it. If you have a grand, you will have to work under the thing. Extra light is essential in both cases.
Sturdy Philips Screw driver. Slow speed electric screw driver or drill with Philips bit. One drill bit the size of the shank of the screws you bought (see below). Counter sinking bit for wood.
First, clean the whole area behind the upright. The grand will be clean already.
Second, Determine which drill bit to use. The size of the bit must be exactly the same as the diameter of the screw shank. You are NOT going to drill a guide hole for the threads.
Third, Drill two holes on every rib-- One on either side of the crack wherever the rib crosses a crack. Drill them about a half inch from the crack. DO NOT DRILL INTO THE SOUND BOARD. DRILL ONLY THROUGH THE RIB. STOP SHORT OF GOING INTO THE SOUND BOARD. Are you getting the point?
You will bungle the whole job if you drill into the sound board. This hole you are drilling is to let the screw turn freely in the rib as it bites into the sound board. If you are unsure of yourself, go invest in one of those drill bits which have a stop on it. Set the stop so that the exposed part of the drill is only as long as the rib is deep.
The spruce sound board is five eighths of an inch thick, and it is not overly hard wood. Any error could put you all the way through the board.
If the crack has opened and warped a lot, drill four holes in the rib-- One on each side of the crack (totalfour at each point where a rib crosses a crack).
Fourth, Using the counter sinking bit, recess the tops of the holes just enough for the screw heads to be flush with the rib. This is neater work, and it is more secure.
Fifth, Put a screw into every hole. Take a look at your work, and see if you have missed any points that need doing. You will have to let some points go undrilled because they will be behind the wood frame of the piano. Don't worry about this.
Now, run the screws in with the electric drill motor and the Philips bit. The best drill motor is a battery operated one which runs slow. If you cannot control it, use the hand held screw driver for the whole process. You must not over tighten, or you will strip out the screw in the sound board. Leave the screw to be tightened the last couple of turns with the hand held screw driver so you have control.
As you can see in The illustration, the tip of the screw may just come through the other side of the sound board. This is good since the threads of the screw are getting a full bite in the wood this way. In the grand piano, you may not like the tips of the screws showing when you look into the piano. Sorry, but if you use a one inch screw, you will not get a good bite in the wood. Better to have the points showing than the loss of volume or a buzz, right?
If you had to put two holes on each side of a bad crack, tighten the outside holes first, then tighten the inside holes. This will bring the board up in stages and prevent stripping out the screws.
Don't cover the screws for cosmetic reasons as restoration shops do. You may want to snug the screws in a few years. You are done. It may not be real pretty, but your piano's sound board is now good for another fifty years.
You can run some Elmer's glue into all of the cracks, but it is not necessary. I usually don't bother.
There are toggle bolts made just for this repair, and you can get them from your tuner. But, they add too much weight to the sound board, and several cracks could cost quite a lot. I don't like them, and I won't tell you how to use them.
Last thought: If the sound board was severely broken up, and yet you got it all back together, you should do two more things.
First, work glue into the space between the sound board and the sides of the cabinet and the floor of the cabinet or the heavy wood frame in the rear. You want the sound board firmly anchored to the frame and cabinet.
Second, you should check the bearing of the strings over the bridge. This can be done with a bearing gage which we sell in the Catalog Tool Section. Sometimes a sound board warps or is different than when new because of repairs, and the sound will not get into the board through the bridges if there is no bearing or a negative bearing.
Filling Cracks in Sound Boards
Repairing the sound board from the back is essential, and filling the crack from above will not be enough alone to secure the sound board and stop the buzzing. Once the process above is complete, you may want to fill the cracks on the top side of the board for cosmetic purposes.
To accomplish this you must be doing a complete restoration and removing the harp for restringing. Once the harp is removed, you must deepen the grooves where the cracks are. Two "V" shaped tools are available, and either will work. The one with tools on each end and a handle in the middle has the most options for work. See this catalog page for sound board repair items.
The groove made by the tool is "V" shaped. This groove will then receive a spruce shim which is shaped the same way. Elmer's Carpenter's Glue must be used, and the spruce shim is tapped into the "V" groove and allowed to dry. The chisel end of the tool is then used to trim the excess of the spruce shim down level with the sound board You must avoid getting into the sound board Some very modest sanding is in order as a last step, and the sound board should then be lightly sanded and a coat of varnish or lacquer added.
Restoring the Crown and Down Bearing of a Sound Board
CAVEAT EMPTOR: This is strictly an act of desperation. If you use this technique, you must take 100% responsibility for the results. I have never done

Viscosity Dip Cup NOVOTEST VZ-P
Viscosity Dip Cup NOVOTEST VZ-P is designed for rapid determination of the relative viscosity (flow time) paints and other related products (Newtonian liquids).
Viscosity cup could be manufactured in compliance with: DIN 53211-87 (DIN 4), UNE ISO DIN 2431, ASTM D 120087 (FORD), ASTM D 4212-93 (ZHAN).
Viscosity cup is available in two models: on a tripod – Viscosity Flow Cup NOVOTEST VZ and a submersible type Viscosity Dip Cup NOVOTEST VZ-P.
Viscosity cup is a reservoir shaped like a funnel with three exchangeable nozzles. Viscosity Dip Cup NOVOTEST VZ-P is produced from stainless steel.
The operating principle of the viscometer is based on determining the time of the expiration of a certain volume of the test liquid through the nozzle.
Viscosity cup – one of the fundamental parameters measuring tool of consumables. When working with varnishes and liquid inks (flexo) it is used to measure the viscosity of the funnel. The viscosity value is determined by the number of seconds (the time at which the liquid runs out of the crater-filled).
Conventional viscosity of paints, is measured by time of continuous flowing (in seconds) of definite quantity of test material through the calibrated nozzle of viscometer. Kinematic viscosity is determined by formulas or by tables and graphs according to measured flow time.

21 Dec Imago provides atomic probe to Australian lab
The Nanostructural Analysis Network Organisation, a major Australian facility for nanotechnology research, said it has commissioned an instrument built by Madison-based Imago Scientific Instruments Corp.
NANO officials said they were pleased with the installation, which Australian and international researchers can use at the University of Sydney.
Imago makes tools to analyse materials down to the atomic scale using technology includig three-dimensional atom probes, which take apart small samples atom by atom to collect data about the composition. Imago says its technology can deliver results in hours.
NANO is funded by the Australian Commonwealth Government, several state governments and industry. It is one of 15 Major National Research Facilities in the country.

6 Functions
6.1 Pattern matching
Pattern matching in function head and in case and receive clauses are optimized by the compiler. With a few exceptions, there is nothing to gain by rearranging clauses.
One exception is pattern matching of binaries. The compiler will not rearrange clauses that match binaries. Placing the clause that matches against the empty binary last will usually be slightly faster than placing it first.
Here is a rather contrived example to show another exception:
atom_map1(one) -> 1;
atom_map1(two) -> 2;
atom_map1(three) -> 3;
atom_map1(Int) when is_integer(Int) -> Int;
atom_map1(four) -> 4;
atom_map1(five) -> 5;
atom_map1(six) -> 6.
The problem is the clause with the variable Int. Since a variable can match anything, including the atoms four, five, and six that the following clauses also will match, the compiler must generate sub-optimal code that will execute as follows:
First the input value is compared to one, two, and three (using a single instruction that does a binary search; thus, quite efficient even if there are many values) to select which one of the first three clauses to execute (if any).
If none of the first three clauses matched, the fourth clause will match since a variable always matches. If the guard test is_integer(Int) succeeds, the fourth clause will be executed.
If the guard test failed, the input value is compared to four, five, and six, and the appropriate clause is selected. (There will be a function_clause exception if none of the values matched.)
Rewriting to either
atom_map2(one) -> 1;
atom_map2(two) -> 2;
atom_map2(three) -> 3;
atom_map2(four) -> 4;
atom_map2(five) -> 5;
atom_map2(six) -> 6;
atom_map2(Int) when is_integer(Int) -> Int.
atom_map3(Int) when is_integer(Int) -> Int;
atom_map3(one) -> 1;
atom_map3(two) -> 2;
atom_map3(three) -> 3;
atom_map3(four) -> 4;
atom_map3(five) -> 5;
atom_map3(six) -> 6.
will give slightly more efficient matching code.
Here is a less contrived example:
map_pairs1(_Map, [], Ys) ->
map_pairs1(_Map, Xs, [] ) ->
map_pairs1(Map, [X|Xs], [Y|Ys]) ->
 [Map(X, Y)|map_pairs1(Map, Xs, Ys)].
The first argument is not a problem. It is variable, but it is a variable in all clauses. The problem is the variable in the second argument, Xs, in the middle clause. Because the variable can match anything, the compiler is not allowed to rearrange the clauses, but must generate code that matches them in the order written.
If the function is rewritten like this
map_pairs2(_Map, [], Ys) ->
map_pairs2(_Map, [_|_]=Xs, [] ) ->
 [Map(X, Y)|map_pairs2(Map, Xs, Ys)].
the compiler is free to rearrange the clauses. It will generate code similar to this
DO NOT (already done by the compiler)
explicit_map_pairs(Map, Xs0, Ys0) ->
 case Xs0 of
 [X|Xs] ->
 case Ys0 of
 [Y|Ys] ->
 [Map(X, Y)|explicit_map_pairs(Map, Xs, Ys)];
 [] ->
 [] ->
which should be slightly faster for presumably the most common case that the input lists are not empty or very short. (Another advantage is that Dialyzer is able to deduce a better type for the variable Xs.)
6.2 Function Calls
Here is an intentionally rough guide to the relative costs of different kinds of calls. It is based on benchmark figures run on Solaris/Sparc:
 - Calls to local or external functions (foo(), m:foo()) are the fastest kind of calls.
 - Calling or applying a fun (Fun(), apply(Fun, [])) is about three times as expensive as calling a local function.
 - Applying an exported function (Mod:Name(), apply(Mod, Name, [])) is about twice as expensive as calling a fun, or about six times as expensive as calling a local function.
Notes and implementation details
Calling and applying a fun does not involve any hash-table lookup. A fun contains an (indirect) pointer to the function that implements the fun.
Tuples are not fun(s). A "tuple fun", {Module,Function}, is not a fun. The cost for calling a "tuple fun" is similar to that of apply/3 or worse. Using "tuple funs" is strongly discouraged, as they may not be supported in a future release, and because there exists a superior alternative since the R10B release, namely the fun Module:Function/Arity syntax.
apply/3 must look up the code for the function to execute in a hash table. Therefore, it will always be slower than a direct call or a fun call.
It no longer matters (from a performance point of view) whether you write
Module:Function(Arg1, Arg2)
apply(Module, Function, [Arg1,Arg2])
(The compiler internally rewrites the latter code into the former.)
The following code
apply(Module, Function, Arguments)
is slightly slower because the shape of the list of arguments is not known at compile time.
6.3 Memory usage in recursion
When writing recursive functions it is preferable to make them tail-recursive so that they can execute in constant memory space.
list_length(List) ->
 list_length(List, 0).
list_length([], AccLen) ->
 AccLen; % Base case
list_length([_|Tail], AccLen) ->
 list_length(Tail, AccLen + 1). % Tail-recursive
list_length([]) ->
 0. % Base case
list_length([_ | Tail]) ->
 list_length(Tail) + 1. % Not tail-recursive

Challenges of Export/Import using the MedBiquitous Virtual Patient ANSI/MEDBIQ VP.10.1-2010 standard - FAQ
What is the MedBiquitous Virtual Patient ANSI/MEDBIQ VP.10.1-2010 standard?
The MedBiquitous Virtual Patient ANSI/MEDBIQ VP.10.1-2010 standard was developed by MedBiquitous, a consortium that develops health professions technology standards. The Virtual Patient (VP) standard defines an XML schema for describing VP resources which allows VP resources to be exported and imported into standard-compliant systems. The standard builds upon the existing Healthcare Learning Object Metadata and SCORM 2004 4th Edition standards.
Effective VPs are widely recognised to be difficult to create, so the goal of the standard is to enable the exchange of these resources between individuals and systems, allowing wider access to examples of these resources, and to allow educators to share and repurpose resources for their learners. The standard (sometimes known as Medbiq VP or even MVP) was used by the EC-funded eViP program to facilitate the development of a shared bank of 340 VPs, and that project contributed to the development of the standard.
##Why do the Virtual Scenarios in the WAVES project use a standard called Virtual Patients? Simpley because, in most cases, there is no difference between the two! A Virtual Patient (VP) is simply a Virtual Scenario (VS) that has a setting in a healthcare context. Most VS can be represented using the VP standard.
The primary reason why the standard is designed for VPs is that those who developed it were working in medicine and healthcare education, so they chose to use the word "patient". However, it soon became apparent that this technology can be used for more than just healthcare. There are some healthcare-specific elements in the VP standard, but they can simply be omitted when a scenario does not need to use them.
What VS systems support the standard?
There is no definitive list of the systems that support the standard. However, the systems used in the WAVES project, Casus and OpenLabyrinth/OLab, do support the standard.
What can the standard do?
The standard allows standards-compliant VS systems to export the cases as content packages in the form of a zip file that is structured so as to adhere to the standardised specification. This means that another standards-compliant VS system can read and import the file and will know where it can retrieve the relevant information from the content package.
As a result, the standard means that you can take a case from one system, and move it to another system. These systems can be different installations of the same system (i.e. if you are moving a VS from one installation of OpenLabyrinth to another) or different systems (i.e. moving a VS for OpenLabyrinth to Casus). You could even use the standard to export and import a VS back into the original system, thus creating a duplicate case that you can edit.
What can't the standard do?
The standard is not a VS "player", and VS files stored using the standard cannot simply be double-clicked, opened on any machine and used to play a scenario. Instead, you need an installation of a standards-compliant VS system, such as OpenLabyrinth or Casus, into which you can import your VS.
By necessity, the standard offers a generic description of a VS resource; that is, it's designed to be a general solution that can apply to all the many different types of VS. However, all the different VS systems offer differing functionality, with a complex range of advanced features. Unfortunately, this means that not all aspects of a VS in a particular system can necessarily be stored within the standard.
As an analogy, it is best to consider the VS standard to be a "lossy" data format, much like a jpeg image. When storing an image as a jpeg, you sacrifice some of the fine detail from the raw image file in order that the file be smaller in size, quicker to load, and more universally readable. The same sacrifice is made when the VS standard is used; some of the system-specific features of a VS case, which will not be usable in another system, will be lost as a result of using the standard as a trade-off to allow the basic fundamentals of the VS to be imported into another system.
If you wish to export a VS and all its advanced features so that you can import it into another instance of the same system, then many systems will offer their own, non-standardised data formats that you can use to achieve this. These formats are unlikely to be able to be recognised by other, different VS systems.
What aspects of a VS does the standard include?
The structure of the standard, and how it describes a VS in technical detail is beyond the scope of this document. The files and schema which make up the standard can be found in full on the MedBiq VP GitHub page. The exact elements of a VS supported will vary from system to system, so you should consult the documentation for your system.
However, in general the standard can include the text-based content and media files, any decision-making or branched options, and any metadata. It may include any MCQs or questions, and mechanisms for scoring or updating values such as blood pressure or heart rate throughout the VS. If your case is created using a visual editor, the standard may also include some details of the layout of your case map.
Where can I find examples of the standard?
You can find examples of VS cases to play on the web on the WAVES website, many of which will also included downloadable content packages that use the standard. Similarly, there are a lot of VS cases freely available to download from the eVip programme website. All these VS are made available under Creative Commons licences that allow them to be freely used and shared subject to the specific conditions of that licence.
How can I use the standard to play a Virtual Scenario?
You will need to have access to a VS system, such as OpenLabyrinth or Casus. In most systems, when you are logged into them with "Author" permissions you will find an option in the system interface to import a scenario using the "Medbiq VP" standard. Select the content that you wish to import, and follow the instructions provided by the system. An imported case can then be played in the same way as any other case.
Please note that you cannot play a case directly from the standardised file.
##What can I expect when I import a VS? When you import a VS case into a system, you should not expect it to be fully playable and completely organised in the new system immediately. Some of the system-specific features of a VS case may have been lost as a result of using the standard, and different systems may interpret the standard slightly differently. This is true of all technology standards; imagine the situation when you open a web page in different browsers and they each work slightly differently. Alhough the web page is standardised (using the HTML standard) each of Chrome, Firefox, Safari and Internet Explorer are required to interpret the information, and will likely do so differently. The standard does however ensure that the fundamentals of the information provided remain intact and readable.
When you first import a VS you should try to play it, first to see if it works at all, and then to identify if there are any modifications that need to be made in order for it to make sense in its new setting. These modifications can be made using the authoring tools of the system to which the case was imported, and may include relinking some media files, resetting the starting point of a case, or changing aspects of the scenario to account for any features that are no longer present in the new system.
The number of changes needed post-import will depend upon the similarity of the importing and exporting system. If the two systems are the same, then you can expect to have relatively few changes required. However, if the two systems are very different in nature, there may be more work involved in adapting the scenario in the new system so that it is logical and coherent to the learner.


Cache Manager
Cache Manager allows you to clear the cache from memory under very specific circumstances.
The standard cache-control expires with a TTL setting. However, there are conditions when we need more control over dynamic content or content that may expire periodically. Here we can delete all cache, delete cache for a specific database, or delete cache within databases that match a specific pattern and apply the rules to a schedule.
 Clear Cache
 1. On the ScaleArc dashboard, click CLUSTERS > Settings > Transparent Cache.
 2. Click the Cache Manager tab.
 3. Configure the fields as follows:
 Field Description Default/User Input
 Delete Cache For all Databases
 This option deletes the entire cache for the selected cluster. Select this option only when you have made major changes to the cluster. Wiping the cache of a busy cluster, where a significant amount of queries are being served from the cache, can put severe strain on database servers.
 Select the radio button.
 Delete Cache for Database
 Select a database to delete the entire cache when you have modified the structure of the database or added or removed major tables. You can also delete the dynamic cache for the selected database.
 Select the radio button.
 Delete Cache for Patterns Within Database
 Select a database and the pattern to delete the entire cache for the pattern added for the specified database. A single pattern may be responsible for caching many queries.
 Warning: Wiping the cache for a pattern results in additional load on the database server for a compute-intensive query that matches that pattern.
 1 Select the radio button.
 2 Then, choose the database and the pattern from the dropdowns.
 Schedule for Later button Schedules the deletion of the cache at the specified hour of the day. See below.
 Delete Now button
 Deletes the cache.
 Click on the Delete Now button.
Set update schedule
You can schedule a cache delete to occur over a period of time.
 1. Click on a delete option (for example, Delete Cache for Database) and select the database from the drop-down.
 2. Click the Schedule for Later button.
 3. Identify the day(s) and hours for your scheduled deletes.
 4. Click on Update Schedule to commit the configuration.
 5. Alternatively, click Back to cancel and return to the previous screen.

Symbols indicating water level can be added to all logs types except depth logs. Water level symbols can be displayed in the borehole view and the cross section view. The lower point of the triangle, i.e. the bottom vertex, is aligned with the depth in the water level table. This is different than symbols in a post log, where the symbol center is aligned with the depth specified in the depth table. Additionally the water level can be displayed between logs on a cross section in the cross section properties. Add the symbols and edit their properties on the Water Level page in the Property Manager.
Note that adding a water level symbol or water level line will not change the depth range of the borehole view or cross section. The borehole view properties or cross section view properties Depth settings, Starting borehole depth, and Ending borehole depth must be manually set to include the water level when the water level is outside the depth range of the logs.
Edit water level data, symbol, and label properties
on the Water Level page.
The General section of the Water Level page contains properties for the water label table and symbol properties.
Check the Display water level symbol check box to display water level symbols on the log. A depth table containing water level information must be selected in the Water level table field for the water level symbols to be displayed.
The water level table is a depth table containing at a minimum hole IDs and depths. An additional parameter column can be included to specify the water level names and water level connections between the logs. If the water level table is already loaded, click the Water level table field and select the table from the list. Click the button to load the Water level table with the Open dialog. The water level table should use the same depth units and direction as the log tables.
The Symbol size property controls the size of the water level symbol. Type a value in page units in the Symbol size field or click the button to change the Symbol size value.
The Symbol alignment property aligns the symbol on the left, center, or right of the log. Click the current selection in the Symbol alignment and select Left, Center, or Right from the list.
The water level symbol is an inverted triangle with between one and three lines at the point. The Symbol style property specifies the number of lines. Click the current Symbol style selection and select One line, Two lines, or Three lines from the list.
The Line Properties section of the Water Level page controls the line properties for the water level symbol. See the Line Properties topic for more information on line properties.
The Fill Properties section of the Water Level page controls the fill properties for the water level symbol. See the Fill Properties topic for more information on fill properties.
The Label Properties section of the Water Level page controls the water level symbol labels.
Check the Show water level name check box to display labels next to the water level symbols. The labels are specified by the Water level name column. Uncheck the Show water level name check box to hide the water level labels.
The water level table can include a name column which is used to connect water levels across logs and display labels for the water level symbols. Select the column containing the water level names by clicking the Water level name column field and selecting a column from the list. The water level labels will be populated by the names in the Water level name column.
Connect water levels by name by checking the Connect water level(s) by names check box in the cross section properties. When the Water level name column does not contain data, Strater connects the water levels automatically. The Water level name column is also used to connect specific water levels between the logs. For example, if borehole 1 contains two water level names A and B and borehole 2 contains three water level names A, B, and C, the two A water level symbols and two B water level symbols will be connected by a line. When the Water level name column contains unique names for the water levels, no water level symbols will be connected as this indicates these are separate water levels.
The Offset method property controls the label offset direction from the water table symbol. Click the current selection and select Center, Left, Top, Right, Bottom, or User defined from the list to change the label offset. Selecting User defined enables the X offset and Y offset properties.
The X offset property moves the label to the left or right when the Offset method is set to User defined. Type a value in page units or click the buttons to change the X offset value.
The Y offset property moves the label up or down when the Offset method is set to User defined. Type a value in page units or click the buttons to change the Y offset value.
The Label angle property rotates the water level symbol labels. Type a value in degrees in the Label angle field or click and drag the slider to rotate the labels. Positive angle values rotate the labels counterclockwise.
The Nudge End Values option moves the starting and ending labels away from the edges of the log pane so that they are completely visible. This 'nudging' occurs only if the label is near the edge of the log pane, otherwise the location of the label does not change. Check the box next to Nudge End Values to move the labels. Uncheck the box to keep the labels in the depth location specified.
The Label Format section includes label formatting properties. See the Format Properties topic for more information on label format properties.
The Font Properties section includes label font formatting properties. See the Font Properties topic for more information on font format properties.

SQL SERVER – Fillfactor, Index and In-depth Look at Effect on Performance
I would like to start this post with an interesting question:
Where in MS SQL Server is "100" equals to "0"? And I am not talking about data types now..
Today I will be presenting the answer to this question and some topics related to it.
Creating Indices in SQL Server is one of the most important tasks of any SQL DBA. Performance of your database is directly depends on your skills and proficiency in creating and maintaining the right number and quality of indices..
As a DBA, you can use "FILLFACTOR," which is one of the important arguments that can be used while creating an index.
Now, the answer to the above mentioned question–
Fill-factor settings of 0 and 100 are equal!
Points to remember while using the FILLFACTOR argument:
1. If fill-factor is set to 100 or 0, the Database Engine fills pages to their capacity while creating indexes.
2. The server-wide default FILLFACTOR is set to 0.
3. To modify the server-wide default value, use the sp_configure system stored procedure.
4. To view the fill-factor value of one or more indexes, use sys.indexes.
5. To modify or set the fill-factor value for individual indexes, use CREATE INDEX or ALTER INDEX statements.
6. Creating a clustered index with a FILLFACTOR < 100 may significantly increase the amount of space the data occupies because the Database Engine physically reallocates the data while building the clustered index.
More about FILLFACTOR
According to MSDN, FILLFACTOR specifies a percentage that indicates how much the Database Engine should fill each index page during index creation or rebuild.
Fill-factor is always an integer valued from 1 to 100. The fill-factor option is designed for improving index performance and data storage. By setting the fill-factor value, you specify the percentage of space on each page to be filled with data, reserving free space on each page for future table growth.
Specifying a fill-factor value of 70 would implies that 30 percent of each page will be left empty, providing space for index expansion as data is added to the underlying table.
The empty space is reserved between the index rows rather than at the end of the index.
The fill-factor setting applies only when the index is created or rebuilt.
The SQL Server Database Engine does not keep the specified percentage of empty space in the pages AFTER the index is created. Trying to maintain the extra space on the data pages would be counterproductive because the Database Engine would have to perform page splits to maintain the percentage of free space specified by the fill factor on each page as data is entered. What it means for you as SQL DBA is that when you set FILLFACTOR at 80 and create Index with these settings, your index has 20% space to grow freely without need for page splits that affect the performance!
You can avoid serious performance issues by providing extra space for index expansion when data is added to the underlying table,.Usually, when a new row is added to a full index page, the Database Engine moves approximately half the rows to a new page to make room for the new row. This is known as a page split.
While making room for new records, page split can take time to perform; it is a resource intensive operation. Also, it can cause fragmentation that leads to increased I/O operations. When frequent page splits occur, it is advisable to rebuild the index while setting an appropriate fill-factor value to redistribute the data. Although a low fill-factor value (>0) may reduce the page splits as the index grows, the index may require more storage space. It will keep creating new, "half-empty" pages, and it can eventually impair performance of your "SELECTs". For example, a fill-factor value of 50 can cause database read performance to decrease by two times. Read performance is decreased because the index contains more pages, thus increasing the disk IO operations required to retrieve the data. Specifying a fill factor other than the default can decrease database read performance by an amount inversely proportional to the fill-factor setting.
Summary
It is recommended to keep default fill-factor for the databases that have prevalence of SELECT queries running against them such as in Data Warehouses, and it is highly advisable to consider changing your default fill-factor settings if you are managing database with a large number of INSERT and UPDATE queries hitting it. In such databases, a nonzero fill factor other than 0 or 100 can be good for performance if the new data is evenly distributed throughout the table.
Consider a situation wherein the existing rows are updated with data that lengthens the size of the rows; for instance, scenarios when you add extra columns to the table. You should consider the use of a fill factor that is less than 100. The extra space on each page will help to minimize page splits caused by extra length in the rows. However, if all the data is added to the end of the table, the empty space in the index pages will not be filled. For example, if the index key column is an IDENTITY column, the key for new rows is always increasing and the index rows are logically added to the end of the index. In such a situation, you should set your FILLFACTOR to 100.
Here is a quick video about how to change fill factor:

 - Hello Pinal
 You gave this code in another post:
 DECLARE @TableName VARCHAR(255)
 DECLARE @sql NVARCHAR(500)
 DECLARE @fillfactor INT
 SET @fillfactor = 80
 DECLARE TableCursor CURSOR FOR
 SELECT OBJECT_SCHEMA_NAME([object_id])+'.'+name AS TableName
 FROM sys.tables
 OPEN TableCursor
 FETCH NEXT FROM TableCursor INTO @TableName
 WHILE @@FETCH_STATUS = 0
 BEGIN
 SET @sql = 'ALTER INDEX ALL ON ' + @TableName + ' REBUILD WITH (FILLFACTOR = ' + CONVERT(VARCHAR(3),@fillfactor) + ')'
 EXEC (@sql)
 FETCH NEXT FROM TableCursor INTO @TableName
 END
 CLOSE TableCursor
 DEALLOCATE TableCursor
 GO
 Is there any way to identify a Clustered index with Identity column in order to set Fill Factor to 100 automatically?

High-Efficiency vs Traditional Washing Machine Comparison Guide
Learn the key differences
Washing machine and dryer in laundry room

How does a high-efficiency (HE) washer differ from a traditional washer, and how do you know if a washer requires HE laundry detergent? To be touted as a high-efficiency (HE) laundry appliance, a washer must meet certain criteria and guidelines concerning water, electricity, and detergent use. In short, it must use less (than a traditional washer) water, energy, and detergent to be called a HE washer. If it falls short of the set guidelines, it cannot sport the HE symbol. While not all high-efficiency washers are front loaders, they do have some visible signs: The HE symbol proudly displayed and a missing agitator.

High-Efficiency vs Traditional Washing Machine: Major Differences
Load capacities are generally larger than with a traditional washer, partially because the agitator is gone (or much shorter), which means fewer washloads to process and less water, detergent, and energy to wash and dry.
A high-efficiency washer washes clothes with a rotating tub to tumble items in the wash cycle. A front-loading HE washer tumbles items back and forth in the water. A top-loading HE washer spins, rotates, and wobbles clothing to wash the clothes. Top-loading HE washers do not have an agitator, but instead, moves clothing using a small center post. A traditional washer uses an agitator to move clothing around the tub.
Key Features
High-Efficiency Washer
This new generation of high-efficiency washers uses a different washing system than its traditional parent appliance, a gentle rotating tumbling action rather than a harsher agitation to get clothes clean. A high-efficiency top loader has a slightly different washing action, a re-designed shorter agitator that draws the load down into the low water and detergent to effect cleaning. HE top-loaders must meet the same stringent guidelines to be called HE washers and either style is efficient when it comes to cleaning performance.
Traditional Washer
A traditional washer will have a tall agitator in the middle of the tub. The agitator takes up some room and reduces the tub's washing capacity.
Appearance
High-Efficiency Washer
There are two types of HE washers. Though they are best known as front-loading appliances, there are also top-loading models.
Traditional Washer
Standard washing machines are top-loading only. There are no front-loading standard washers.
Best for Appearance: High-Efficiency Washer
You'll be able to choose from two styles if you buy a HE washer. Front-loading HE washers are considered to be more contemporary in style.
Sizes
Both HE and traditional washers now come in all sizes and capacities. The only difference is that you may find some HE top-loaders are slightly taller and wider than a standard top-loader. That means deeper tubs that require reaching down into.
Repair and Maintenance
High-Efficiency Washer
The biggest difference in using a high-efficiency washer is that it needs more care than a basic washer. Since water use is low, there's a tendency with some washers to not flush the soap and wash load residue properly, leaving damp accumulations within the washer, which can cause mildew to grow.
It's recommended that the door and dispenser drawer on a high-efficiency washer be left open in order for the door gasket and interior drum to dry properly. In addition, with a high-efficiency washer, you must run the machine-cleaning cycle as recommended by the manufacturer or more often, to reduce the risk of bacterial growth.
Some consumers have found that more maintenance or cleaning of other washer parts is necessary, while others have merely lowered their detergent use and/or have chosen to not use liquid softener in the washer, but rather fabric sheets in the dryer, to reduce residue build-up in the washer.
Traditional Washer
A standard washer doesn't require as much daily care as a HE washer. One issue you will need to watch for is the potential to overload a top-loading standard washer. Overloading will cause the drum to wobble or stop spinning. Another issue is the agitator that may stop working due to various factors.
Best for Repair and Maintenance: Traditional Washing Machine
A traditional washer won't have as much of a learning curve when it comes to usage, repair, or maintenance. A HE washer has a higher learning curve which includes daily maintenance.
Wear and Tear on Clothing
High-Efficiency Washer
The tumbling action of a HE washer uses gentle, but efficient force to deep clean clothing. You'll need HE detergent to use with a high-efficiency washer. Most HE washers have sensors to adjust water temperature, level, and spin to match the load so there's no guesswork once you've chosen a wash cycle. Cycle times are much longer partly due to the low water use—it takes longer to get clothes clean.
Traditional Washer
The agitator used to rotate clothing clockwise and counterclockwise also cleans clothing well, but it can be rough on clothing.
Best for Wear and Tear on Clothing: High-Efficiency Washer
HE washers are gentler on clothing. That means even delicate pieces can last longer than they would if they were washed by agitation. In addition, high-speed spin cycles remove more water from the load, resulting in shorter drying times, which is another way to make clothing last longer.
Since a high-efficiency washer uses less water, low-sudsing HE detergent must be used in these washers in order for cycles including the rinsing action to work as designed. This applies regardless if the washer is top-loading or front-loading, as long as it has the HE seal.
Water and Energy Use
High-Efficiency Washer
Lower washer water levels in a HE washing machine mean there's less water to heat which means less energy use.
High-efficiency washers are also Energy Star compliant. Since a HE washer already meets stringent energy guidelines which are higher for high-efficiency, it has already met the (lower than HE) targets to carry the Energy Star compliance seal. Accompanying dryers must also meet certain criteria for lower energy use to carry the HE symbol. The Energy Star program has not been extended to dryers.
Traditional Washer
Traditional washers are not Energy Star compliant. The certification is given to clothes washers without a central agitator because the newer technology cuts energy and water consumption.
Best for Water and Energy Use: High-Efficiency Washer
A HE washer uses less water per load. Though the HE washer's wash cycle is longer, the appliance uses less energy to heat hot water, which saves money over the long term. A traditional washer uses more water and energy in general per load than a HE washer.
Installation
The installation will be similar whether you are buying a front-loading or top-loading HE or traditional washer. If you have plumbing in place already, installation requires making the drain and water supply connections, leveling the appliance, and plugging it in.
Cost
High-Efficiency Washer
Though high-efficiency washer and dryer prices have become more competitive, they still do cost more. But the range of laundry appliance sizes and capacities has increased, making it easier for the consumer to find the size of washer and dryer they need.
Traditional Washer
A regular top-loading washing machine will be less money than even a top-loading HE machine. But the two types of washers are now closer in price than ever before.
Best for Cost: Tie
A top-loading regular washer may cost a bit less to buy than any type of HE machine. Regular washers don't need slightly pricier HE detergent, either. But it may pay to spend a bit more on a HE washer to benefit from the long-term water and energy savings.
Lifespan
Any washer should last over 10 years. Whether it's a HE washer or traditional washer, you should expect to have it between 10 to 15 years. It can last longer as long as it's installed on a flat surface, isn't overloaded, and you use the correct detergent.
The Verdict
Overall, you'll find a large selection of both HE and traditional washers, and all at various price points and sizes. HE washers are becoming more commonplace. For efficiency, a HE washer will clean larger loads with less water and less energy. You will need to do a bit more daily maintenance to eliminate any mold and mildew build-up. You'll also need to pay a bit more for HE detergent that doesn't suds up as much as regular laundry detergent.
In addition, if you purchase a HE washer, you'll have to learn the ropes on using the appliance and HE detergent. Similar to high-tech top loaders, most HE washers have numerous wash cycles and settings—more than you would find on a basic washer, which may take more time to explore or understand. If you don't like long cycles, it may mean experimenting with wash cycles to find a shorter one that still gets your clothes clean.

Three dimensional numerical modelling was used to examine the fracture responses around cavities in rock masses experiencing the stress of excavation. In addition to the primary fracture zone in the near-field, numerical modelling generated a second fracture zone in the far-field and an elastic non-fracture zone between the two fields, i.e., fracture and non-fracture zones occurred alternately around a deep cavity. Further research illustrated that the dynamic load and static stress gradient are two necessary precursors for a far-field fracture in the excavation process. Neither quasi-static loading nor homogeneous stress conditions could induce a far-field fracture. A simple theory is introduced, suggesting that multiple fracture zones occur during excavation due to both the initial stress gradient and the dynamic load. This finding indicates that it may be possible to induce continuous rock fractures in deep underground rock masses by employing optimal excavation methods to generate multiple contiguous fracture zones. © 2013 Elsevier Ltd.

hw.design at the 2008 designparcours
On the occasion of this year's designparcours 2008 in Munich from 28 February to 9 March 2008, hw.design developed the website regarding the ideals of different generations.
The website enables users to experience the ideals of generations in the past and today, both visually and interactively. At the centre is the individual website visitor, who is asked to describe the ideals of their generation or their personal ideals for the future in the form of a brief statement. Each visitor must place their own building block by either responding to previous statements or contributing to the overall shape of the interactive graphics that are created in the statement process.
Visitors are asked to enter their age, origin and personal attitude to life, which can then be displayed through a variety of different diagrams. In addition to the colour coded implementation reflecting the date on which the entry was made during the designparcours, various other aspects are also visualised in this way.
The website, developed as part of the 2008 designparcours on the topic of generations, puts the spotlight on the vision and understanding of each generation with regard to what the future holds.

Pigeon Fermented Mixed Vegetables is a product that consists of a blend of various vegetables that have undergone a fermentation process. Fermented vegetables are known for their tangy, complex flavors and are often used in Asian cuisines as condiments, side dishes, or ingredients in cooking.
The exact composition of Pigeon Fermented Mixed Vegetables may vary, but it typically includes a combination of vegetables such as cabbage, carrots, radishes, and other seasonal vegetables. These vegetables are fermented using traditional methods, allowing beneficial bacteria to develop and enhance the flavors.
During the fermentation process, the natural sugars in the vegetables are transformed, resulting in a slightly sour and tangy taste. This fermentation also promotes the growth of probiotics, which are beneficial for gut health.
Pigeon Fermented Mixed Vegetables can be enjoyed in various ways. They can be served as a side dish alongside rice or noodles, added to soups or stews for added flavor, or used as a condiment to provide a tangy and refreshing element to dishes.

On December 14, 2023, the SEC published its review ("Review") of the accredited investor definition. Section 413(b)(2)(A) of the Dodd-Frank Wall Street Reform and Consumer Protection Act requires the SEC to review the accredited investor definition, in its entirety, as it pertains to natural persons, at least once every four years to determine whether the requirements of the definition should be adjusted or modified for the protection of investors, in the public interest, and in light of the economy. The Review does not contain any recommendations or proposals to change the accredited investor definition. Rather, the Review is a detailed consideration of whether the accredited investor definition is an accurate measure of the extent to which accredited investors have the financial sophistication and ability to sustain the risk of loss of investment, and access to information to "fend for themselves." This eUpdate highlights certain notable points from the Review.
Composition of the Accredited Investor Pool
According to the Review, the SEC estimates that the percentage of U.S. households that qualify as accredited investors has grown steadily in the four decades since the definition was adopted, from 1.8% of households in 1983 to more than 18% of households in 2022. This appears to be largely due to the fact that the natural person accredited investor thresholds have not been adjusted to reflect inflation. If the natural person accredited investor thresholds were adjusted to reflect inflation since their initial adoption through 2022 using the Consumer Price Index, the net worth threshold would increase from $1 million to $3,037,840, the individual income threshold would increase from $200,000 to $607,568, and the joint income threshold would increase from $300,000 to $911,352. The number of individuals who qualify as accredited investors has likely also increased as a result of the SEC's 2020 amendments to include as accredited investors individuals holding in good standing certain professional certifications or designations, as well as knowledgeable employees of certain private funds. Further, the Review noted that a significant percentage of investors' assets, for purposes of determining accreditation, are retirement savings, which was not the case when Regulation D of the Securities Exchange Act of 1934 was adopted in 1982.
History of Suggestions to Revise the Accredited Investor Definition and Conclusion
The Review goes on to summarize the proposals and suggestions by the SEC and commenters to revise the accredited investor definition over the years. Many of these suggestions and proposals were focused on the financial thresholds of the definition, such as adjustments to the thresholds to account for inflation. The SEC concluded the Review by soliciting the public's views and feedback on the matters discussed in the Review.
While the Review does not contain any suggestions or proposals to change the accredited investor definition, it clearly expresses a concern that the financial thresholds of the accredited investor definition, which have not been adjusted in the four decades since the definition was adopted, may not be an accurate proxy for an investor's financial sophistication, and ability to sustain the risk of loss of investment and fend for themselves. Dorsey will continue to monitor and report on any developments by the SEC to change the accredited investor definition.
 "Review of the "Accredited Investor" Definition under the Dodd-Frank Act" (December 14, 2023) available at _URL_
 The SEC estimates that 31% of households would qualify as accredited investors by 2032 using the Consumer Price Index if the thresholds are not adjusted for inflation going forward.

The Life and Exploits of Three-Finger'd Jack by William Burdett is a novel about Jack Mansong, an African military hero, who was betrayed into slavery and taken to Jamaica. Jack ran away from the plantation where he worked and escaped into the mountains, where he led a gang of sixty rebels who fought, during the 1780s, for freedom that was not attained until well over fifty years after. Jack Mansong is one of the unsung heroes of Jamaica.
Quasheba's Revenage is an adaptation of a story originally written by Charles Dickens, William H. Ainsworth, and Albert Smith. When a young slave woman's husband is killed through the connivance of other jealous slaves, she takes revenge through an ingenious scheme that bolsters her resistance spirit and eventually leads to her freedom.
Runaway Cudjoe by George Cruikshank is a novel based on a true story about a runaway slave in 1820s Jamaica. Cudjoe escapes into the mountains where he lives for the first time in freedom with other runaways. Their liberty is constantly under threat from the British military on the hunt. This is a story that reveals the strong resistance spirit of Jamaicans in the past when they had to fight against slavery.
Kitty's Emancipation and Other True Stories of Jamaican Slaves
Kitty's Emancipation and Other True Stories of Jamaican Slaves by Henry Bleby, is a collection of four short stories: "Kitty's Emancipation," "Old Moggy," "Old Hope," and "Betsey's Education." The stories recall the experiences of slaves in Jamaican, before the advent of emancipation in 1838. Some of the incidences are genuinely beautiful and help to reinforce one's hope in humanity, while others are heart-wrenching and painful to read. At the same time all are testament to the strong survival spirit of the Jamaican people.
Lovely Norah and Other Ladies of St. Molasses Island
Lovely Norah and Other Ladies of St. Molasses Island by George Hammond Hawtayne, is a collection of five short stories: "Miss Elsie's Hospitality," "Ginger and Mrs. Stump," "What Happened to Abba Clarke?" "The Hurlock Sisters," and "Lovely Norah." The stories explore some comedies, as well as the various complexities of life on a fictional Caribbean island during the 18th Century colonial period.
Becka's Buckra Baby
Becka's Buckra Baby by Tom Redcam (Thomas Henry MacDermot), is a novel that explores the social implications and unforeseen consequences when a young lady gives a little black girl the Christmas gift of a white doll. The novel was first published in1905, and is claimed by many to represent the beginning of modern Anglophone Caribbean prose writing.
Tom Redcam was a pioneer of stories written by Jamaicans, about Jamaica, for Jamaicans. Today, the main library on the island, as well as the street on which it is located, is named in his honour.
Maroon Medicine by E. Snod (E. A. Dodd) is a collection of four short stories that portray the lighter side of people in Jamaica. First published in 1905, these fictional stories: "Maroon Medicine," "Paccy Rum," "The Red Cock," and "The Courting of the Dudes," are sketches from rural Jamaican life in the early 1900s, and as such are both extremely humorous and immensely valuable.
The Jonkonnu Mask and Other Survival Stories
The Jonkonnu Mask is a collection of ten stories about children who survive against all the odds. Meet Aisha who goes to live with her mother in a foreign country, Boogsie the car washer, the Windscreen Boys, a scholarship girl, and determined Omari, Jamila, and more. These children not only survive, they go on to build lives that are honest and valuable.
Old Jamaica Conversations
Old Jamaica Conversations is a collection of ten conversations that recall the Jamaican people's unique history and culture. The various conversations recapture the cruelties of the Atlantic slave trade and slavery, the difficulties the slaves faced when they wanted to convert to Christianity or worship freely, the joy many felt on the eve of emancipation in 1838, insightful proverbs and parables, as well as different view of the future of the island nation. Included in the collection are: "No Rum! No Sugar! Or, The Voice of Blood," by an anonymous author; William Knibb's "The Persecuted Disciple" and "The Death of a Female Slave;" William Jameson's "I Never See Goshen People So Quiet;" James Phillippo's "Seven Christian Dialogues;" Joseph Williams's "Ashanti Proverbs in Jamaica;" Charles Joseph Rampini's "Jamaican Proverbs;" and John Henderson's "The Politics of a Jamaican Negro," and "The White Man's Politics."
Old Jamaica Journeys
Old Jamaica Journeys is a collection of ten revealing journeys people took to and through the island of Jamaica. First is Alexander Falconbridge's account of sailing with slaves to the island, which is followed by Henry Bleby's "Just to Look at Massa Minister." The complexities of the island are recalled in Charles Rampini's "To the Bullhead" and "In Bluefields Bay;" Edgar Bacon's "Port Antonio;" Charles James Ward's "The Blue Mountains;" John Henderson's "Bog Walk;" Joseph Williams's "Weird Happenings," (about the earthquake of 1907); and finally, H. G. De Lisser's "Kingston," and "On the Way to Montego Bay."
Old Jamaica Memories
Old Jamaica Memories is a collection of ten articles that give glimpses into how ordinary people lived on the island through the years. Alexander Barclay's 1827 account of plantation life is valuable, as too Benjamin McMahon's "Sarah from Harmony Hall." The other memories are: James Edward Alexander's "A Favoured Isle;" Henry Bleby's "I Saw the Monster Die," (about a watch night service on the eve of emancipation – July 31st, 1834); Jas Thome and Horace Kimball "A Day with Special Magistrate,
Richard Hill," during the apprenticeship period; James Phillippo's "Clarkson Town" that describes one of the first free villages established by former slaves; Theodora Elizabeth Lynch's "The Cotton-Tree;" Robert Hill's scrutiny of Jamaicans in the 1890s; Ralph Hall Caine's recollection of the 1907 Kingston earthquake; and finally an exploration of unique Jamaican religious observances with H. G. De Lisser's "Revival Time."
Old Jamaica Notes
Old Jamaica Notes is a collection of extracts from books that address different aspects of life, or particular experiences, in old-time Jamaica. The collection begins with Robert Montgomery Martin's "From Columbus to Cromwell," and traces the early history of the island, from the arrival of the Spaniards to the British capture in 1655. The next account is Emmanuel Heath's "I Saw the Earth Open," an eyewitness account of the1692 earthquake that destroyed the pirate's lair of Port Royal. The other notes are: Charles Joseph Rampini's "The Obeahman;" Alexander Barclay's "Catching Fish and Crabs;" Frederick John Robinson's "What Happened to Eleanor James;" Michael Scott's "John Canoe," an extract from his celebrated novel, Tom Cringle's Log; Mary Gaunt's "The Plantation Books," William Knibb's "The Planning of the Christmas Rebellion in 1831;"
Algernon Aspinall's, "The Legend of Rose Hall;" and finally John Henderson's the light-hearted "Love Letters."
Old Jamaica Poems
Old Jamaica Poems is an anthology of twenty-four great poems about Jamaica that were written during the last three-hundred years. In many cases the verses are preceded by a brief account of the poet's life, such as the interesting chronicle of Francis Williams, a Jamaican who was probably the first negro poet in all of the Americas to have his poems published. Other poets represented in the collection are: Philip Morin Freneau, John Marjoribanks, Edward Rushton, Charlotte Turner Smith, Emily Capadose, Richard Robert Madden, Tropica (Mary Adella Wolcott), Henry Shirley Bunbury, Tom Redcam (Thomas Henry MacDermot), Eva Nicholas, and Claude McKay.
Old Jamaica Stories
Old Jamaica Stories is an anthology of stories that cover a range of topics at the heart of the island's history and culture. The collection begins with Henrietta Camilla Jenkin's "The Runaway," an extract from her1859 work, Cousin Stella. Next is a story from another renowned novel, Hamel, The

Use of groundwater from gravel beds could help cut energy and carbon emissions by half
The Tate Modern will next week begin work on a plan to use groundwater for heating and cooling its £215m Herzog & de Meuron-designed extension.
On Monday, consulting engineer Max Fordham Partnership will begin drilling 10m boreholes into the gravel which lies deep beneath the site, on the Thames' former flood plain. The project is thought to be the first of any scale to take water from Thames gravel beds.
Previous schemes in London, including the Royal Festival Hall refurbishment, which Max Fordham also designed, have made use of the water contained in a chalk aquifer, 100-120m below ground level. However, this option is now highly regulated by the Environment Agency because of concerns that aquifers which supply drinking water could be contaminated.
The use of the gravel water at Tate Modern is part of a strategy to cut 54% of energy and 44% of carbon dioxide emissions from the building, which is scheduled to open in 2012.
Mark Nutley, Max Fordham's project manager, said the system would use the differential between the air temperature and the 14-15ÞC underground water to heat and cool the space. This "open loop" system uses a heat pump to extract energy from the groundwater to heat the building in the winter and cool it in the summer. The water is then fed back into the gravel bed.
US engineer Parsons Brinckerhoff is providing technical expertise on the borehole procedure.
The project is thought to be the first of any scale to take water from Thames gravel
The extension will still draw 70% of its heat from the neighbouring EDF substation, which is being moved to accommodate it.
The scheme received planning consent on 1 April.
