His general area of research focuses on how the active enzyme species generated during the blood coagulation process are regulated by both specific protease inhibitors present in blood, by cell-dependent processes or by various pharmacologic agents designed to suppress blood clot formation and propagation. The experimental approaches include studies in phlebotomy blood and reaction systems constructed with varying ensembles of purified proteins. The overall goal is to delineate the sequence of pro and anticoagulant events that allow the blood coagulation system to form a barrier that plug leaks in a vessel without blocking flow through the vessel. The empirical results from these studies and those from other laboratories are then translated into the existing reaction pathway framework of a mathematical model of coagulation developed by the Mann laboratory. Expansion of the reaction pathways encompassed by this model to facilitate interpretation and design of empirical studies, and transformation of this model into a research tool with clinical applicability are the long term goals of the modeling effort.

An online stamp generator is a tool that allows business owners to create customized stamps for different purposes, such as packaging, marking invoices, and even authenticating important official and legal documents. Hence, in this article, let us discuss everything that a business owner should know about an online stamp generator or a stamp maker online.
How does an online stamp generator operate?
A stamp maker online or online stamp generator comes with a specific software application that allows customers to design and customize their stamps online. Users can select from various kinds of pre-designed templates, then add their own text, and next can upload images. After that, the online stamp generator can create a specific digital file of the stamp design, which can be easily downloaded or even printed on a self-inking stamp or a rubber stamp.
What are the different types of stamps that can help you with your business?
An online stamp generator can develop various types of useful stamps, such as:
- Pre-inked stamps
These types of stamps have an ink reservoir built into the stamp pad. They are capable of offering a high-quality impression and can be re-inked when the ink runs out.
- Self-inking stamps
These are another type of stamp that has an integrated ink pad. This ink pad can automatically re-ink the stamps after each imprint or impression. These kinds of stamps are more efficient and convenient than many other kinds of stamps.
- Rubber stamps
These are other kinds of stamps that have a certain rubber surface mounted on a plastic or wooden block. You can use these rubber stamps with an ink pad to transfer ink onto paper or even some other materials.
Important features do business owners consider when designing an online personalized stamp?
When designing a personalized online stamp, business owners need to keep in mind some important factors. Such as follows:
- The text of the stamp
The text on the online stamp needs to be both clear and legible. It needs to include important pieces of information, such as the name and address of the business, contact information, incorporating state, and many more.
- The size of the stamp
The size of the online stamp has to be appropriate for its intended use. A stamp that is larger in size can be a lot more visible but may not be accurate or suitable for making an impression on small items, such as envelopes.
- The color of the stamp
The color of your digital or online stamp needs to be consistent with the color scheme of your brand. It needs to be easily readable and contrast with the background.
- The logo of the stamp
The logo of your online and personalized stamp has to be of highresolution and needs to represent your brand as accurately as possible. It has to be placed in a prominent location on the stamp.
Therefore, to make logo stamps with great perfection, a business owner needs to check a few things, such as:
- They need to select a clear and legible font for the text.
- They must choose a high-resolution image.
- They need to select the appropriate size of the stamp as per their needs.
- They should use an accurate color scheme and even check the spelling and accuracy of the information provided in the stamp.
What are the different types of ink pads you can use to make an impression on your online stamp?
There are different types of ink pads that business owners can use. Such as:
- Water-based ink pads
These types of ink pads are perfect for rubber stamps and hence, can offer a quick drying time. These stamps are not suitable for non-porous or glossy materials.
- Pigment ink pads
These kinds of ink pads are great for use with your pre-inked stamps and can offer a high-quality impression. These impressions are more resistant to fading and are even suitable for use on various types of surfaces.
- Solvent-based ink pads
These types of ink pads are ideal for self-inking stamps. Business owners can use these to create stamp online to create an impression on non-porous or glossy surfaces. They provide a longer drying time and are a lot more resistant to smearing or smudging.
Types Of Stamps That A Business Owner Should Have
There are mainly four types of stamps that a business owner must have. Such as:
- Bank Stamps
These types of stamps are important for almost all business owners. Professionals can use this stamp to show the authenticity of checks and documents, and other business professionals may utilize it to track and manage the status of various types of financial transactions.
These stamps are useful in both routine stamping situations and one-off situations. This kind of online stamp helps by saving time and reducing fatigue when stamping large quantities of important documents that need to be properly authenticated with a date.
The places where you can use your bank documents are paychecks, checks, account summaries, banking statements, and many more.
- Signature stamps
When you need to sign a stack of important official documents at once, the time it needs to sign each one by hand may be a really tough job. So, in this situation, you can just rely on an online stamp generator and create a stamp online to complete your task within just a few minutes.
You can create a good quality signature stamp and then can sign all your important papers quickly and easily. Places where you can use your signature stamp are letters, notices, thank you notes, employee contracts, packing slips, licenses and permits, and many more.
- Address stamps
The name and mailing address of an organization are generally imprinted onto an address stamp. With this kind of stamp, you can build strong brand awareness and also a good relationship with your customers. The utilization of an address stamp with your company logo is a labor and time-saving way to produce an attractive letterhead or return address.
Places, where you can use your address stamp, are packing slips, contracts, letterheads, business cards, sales order receipts, thank you notes, etc.
- Date stamps
Date stamps can be used in a large variety of official and legal documents that can reduce your labor to a great extent. You can use your date stamps on papers, like receipts, food packages, contracts, notices, letters, permits, invoices, inventory, and many more.
However, no matter what kind of online stamp you wish to create, you should always trust a reliable and professional online stamp generator, like Stamping and Blogging.
How can you create a stamp online using Stamping and Blogging?
By opting for Stamping and Blogging, you just need to go through a few easy steps to make logo stamp. Such as:
- First, go to the designer page of this online stamp generator and choose "New stamp."
- Then set the accurate size of your customized online stamp.
- After that, insert the "Circle" option and write down the text that you want in your customized stamp.
- Next, upload an image as per your choice, and finish the design after changing the position and size of the image.
- Lastly, you can download it if necessary or even send it for production.
Therefore, creating an online stamp with the help of a reliable stamp maker online, such as Stamping and Blogging can always help your business in many ways.

15 Terrifying Ancient Medical Practices
We all know medical knowledge was lacking centuries ago. However, there were more crazy ancient medical practices than you might think. See 15 of them.
If you're somehow lucky enough to have the smarts to make the first time machine and travel back to the ancient world, try not to get sick while you're there. Those ancients did some crazy, terrifying things in the name of "medicine." Some ancient medical practices seem insane and barbaric today.
Sure, Hippocrates might have said "do no harm" nearly 2,400 years ago, but there were still plenty of pseudo-medical practices going on that we're pretty sure did some harm. Even if some of these medical procedures did help the patient, they're still horrifying.
See 15 such ancient medical practices that may shock you.
15.) Heroin
Heroin used in ancient medical practices
Heroin might be the street name given to a form of morphine no longer used in American hospitals today, but it used to be a medication given over the counter. Herbs, among many other things, have been used to make medication since ancient times, but heroin took a special kind of pain away from issues.
People used it for headaches, coughs, and much more. They even gave it children, with one medical "professional" saying there was no risk in developing a habit of its use. Well, it did get rid of that cough once.
14.) Human Remains
Skulls used in ancient medical practices
For centuries, people assumed that the things that came out of humans, as well as their remains, could be used in medical treatments. Not only did people think urine could help their teeth, but they also felt human blood and skulls could be used to help treat sicknesses.
People felt this could be useful as far back as the 1500 and 1600s, which was a time when other, better medical knowledge was present. The poor who could not afford human blood, for example, would attend executions and grab some. Vlad the Impaler, you have more possible vampires near.
13.) Rocks
Rocks used in ancient medical practices
Not to be confused with "The Rock" Dwayne Johnson, a rock like you might find right outside was used as a tool for centuries. They might be part of some of the oldest ancient medical practices known to man. It was used most often in dentistry where a doctor of sorts used it to help knock a tooth out. Over time, hammers made more sense and slowly gained prominence.
Today, hammers and drills are still used in some forms of dentistry, just not to the extent as it was used ago. Rocks were also ancient forms of anesthesia too. We'll let you figure that one out.
 12.) Lobotomies
lobotomies used in ancient medical practices
While things like Lobotomies were eventually put to an end, people felt this practice was useful. They never once showed accurate results in this practice that could not be attributed to another source. However, this was not the first time a method like it existed.
Despite this, the concept behind a Lobotomy was that it could cure any horrible brain condition a mentally ill person might have. It was proven not to work, so seeing ancient medical practices as crazy as this go until the 1980s is shocking!
11.) Cocaine
Cocaine used in ancient medical practices
Springboard Recovery
People have used cocaine for several different things over the years. Just like most things, people thought it helped with headaches. Cocaine did help for this, as it helps in the sinus department. However, the real idiotic assumption was that it helped with depression.
To be fair, it is hard to be depressed when you're on a cocaine high, so technically, it sort of worked. However, using cocaine to cure depression belongs in the list of ancient medical practices we shouldn't try.
10.) Forced Seizures
Seizures used in ancient medical practices
Kidney Buzz
While doctors to this day will induce medical seizures, they are only done for specific reasons under proper care. Decades ago, the idea was less intelligent. The concept in the 1940s and 50s was the use of electroconvulsive therapy that shocked someone into seizing or convulsing. A common problem afterward was the brain damage or death the seizure called.
The concept of using seizures as treatment dates back to the 1500s, but the early use of electricity was pretty much zero. They'd use various forms of light to cause them, similar to how they can be started for some even today.
9.) Malaria Used to Treat Syphilis
Malaria used in ancient medical practices
If you have one life-threatening disorder, it makes sense to battle it with another potentially deadly thing, right? Well, not so much. However, malaria being used to treat syphilis during the 1920s.
The concept was invented by Austrian Physician Julius Wagner-Jauregg, who discovered that malaria-induced fevers had some effect on syphilis symptoms. The man even won the Nobel Peace Prize for this too. Seriously!
Forget the fact that fevers alone have been shown to help with numerous things, regardless of Malaria. To the shock of no one, several patients died from this. Ancient medical practices like this make you realize how lucky we are to live today.
8.) Arsenic
Arsenic used in ancient medical practices
Arsenic is often used today as a bioweapon of sorts, and it has been mostly eradicated from medical use in civilized nations around the world today. Before this, people used arsenic in several ancient medical practices around the world for a long time.
The typical things it treated were fevers and headaches. Funny enough, in small doses, arsenic can assist in several medically useful treatments. However, we no longer need it today due to having other medication that does not also kill people as easily as arsenic does.
7.) Castration
Castration used in ancient medical practices
SB Nation
The medical use of castration was rare because men generally don't want this procedure. However, Babylonians felt that it could be useful as a last resort. Some people used this practice for what we'd call a UTI today or even a kidney infection. At the time, no one knew what these were or how to treat them.
However, the most common usage of castration came for eunuchs. For several harems under the Assyrians and Babylonians, the testicles needed to be removed to be a eunuch. Turkish people forced the removal of both the testicles and penis. By the way, they were not put to sleep to do this, and the testicles were crushed to do the castration. Ouch!
6.) Mercury
Mercury used in ancient medical practices
JK Studios
People have used mercury for hundreds of years to help with countless different ailments. Its use is one of the most common ancient medical practices known to man. Ancient Persians and Greeks felt it was useful as an ointment while second-century Chinese felt it increased lifespan and vitality.
The most famous use of mercury gone wrong was with Chinese Emperor Qin Shi Huang, who thought a mercury pill would make him immortal. From the time of the Renaissance all the up to the 20th Century, we used mercury to treat sexually transmitted diseases too. Most who used mercury died from liver or kidney damage caused by it poisoning them.
5.) Sacrifice
Sacrifices used in ancient medical practices
My Jewish Learning
One of the ancient world's most common methods of warding off or curing illness and injury was to sacrifice something (often someone) to the gods. This practice might seem silly today, but it did not feel ridiculous if you were the cow, sheep, or human being killed to repair the health of the emperor, chieftain, or another important person.
You might even find this personal at times. Humans who were sacrificed often volunteered, shockingly. Some found it to be a great reward to die for someone else. They were what we call weird people.
4.) Ancient Anesthetics
knockouts were used in ancient medical practices
Modern anesthesia (and similar anesthetics) were not in regular use until well into the 19th century. However, there were a few methods for helping reduce the suffering of a patient during a medical procedure. They boiled down to essentially three things: drugs, alcohol, or being knocked over the head.
The latter was especially popular in ancient Egypt, where doctors started most surgical procedures by a Stooge-esque clunk to the noggin. Remember the rock from before? It was less common for Egyptians. They typically used something more practical when doing ancient medical practices like that of early brain surgery.
3.) Ancient Ophthalmology
Clean rooms used in ancient medical practices
Atlanta Commercial Cleaning Service
The Greco-Roman physician Galen (Greek by heritage, Roman by birth) is considered one of the first people to practice some modern surgical techniques. Galen was the first to implement such things as trying to use a clean, sterile area to perform operations in eye surgery.
We're still glad not to be one of the patients whose cataracts was being "cured" by injecting a needle directly into the eye, hoping to sort of suck the thing out.
2.) Bloodletting
bloodletting used in ancient medical practices
Believe us when we say there is nothing humorous about the "humors." The humors were those pesky (meaning nonexistent) bodily fluids that ancient and medieval people thought had to be kept "in balance" to keep you healthy. They were blood, black and yellow bile,

of Gymnastics on Balance Beam
This apparatus is rather lately used in competitive gymnastics. However, as apparatus for balancing it is actually as old as later body exercises. It might started with a "horizontal laying, totally round pine tree trunk..." to balance on. Jahn called it later "Schweben" (engl.: floating) which is the origin of the present name still used in Germany. The lower part of the long "Schwedenbank" (Swedish bench) still integrates the balance beam.
1934 the balance beam
was part of the world championships in Budapest for the first time. That
was also the first time actual women's international championships took
The beam was only 8 cm wide. Nowadays, this discipline is not only a demonstration of feeling for balance but also of acrobatic of highest difficulty in the artistic area.
This apparatus is rather lately used in competitive gymnastics. As apparatus for balancing, however, it is actually as old as later body exercises. Already Johan Christoph GutsMuths (1759 - 1839) dedicated one chapter to balancing in his pioneering work "Gymnastics for the Youth". His beam was a "horizontal laying, totally round pine tree trunk... of about a length of 64 feet (ca. 20 meters!). The posts wearing the trunk were of that kind that the height can be changed."
Friedrich Ludwig Jahn (1778 - 1852) takes GutsMuths' balancing on the round beam over in his "Deutsche Turnkunst" (German Art of Gymnastics, 1816), but being a declared enemy against foreign words he calls it "Schweben" (floating):
"Schweben means being in balance: in rest as well as in action". Jahns "Schwebebaum" is "a slim, straight-grown and smooth resinous pinewood or fir tree trunk; the longer, the better, and not good under a length of 40 feet and a diameter of 10 inches at the end of the trunk. It rests between to pairs of strong posts on bolts of iron which can be put high or low". Jahn did not attach great importance to perfect stability of the apparatus, on the contrary: "It must not sway too much, not too little, but it must have the proper life" (The German Art of Gymnastics, 1816).
Later on this (low) balance beam was taken over into school's physical
education by German followers of Ling's system, (Hugo
Rothstein; first director of the Prussian Central Institution
of Gymnastics in Berlin), even though Rothstein lost influence because
of the "quarrel about bars" in 1863. Gymnastics pioneers Spieß
(1810 - 1858) and Kloß
(1818 - 1881) thought highly of this low balance beam as apparatus for
As competition apparatus
this low and narrow balance beam was never used.
From now onwards balance beam became a standard apparatus in women's international competitive gymnastics. The routines tended to include an increasing number of acrobatic elements. As a consequence the wish for firmer foothold grew permanently stronger to enable gymnasts to perform more difficult leaps and rolls.
The stability of the
5 m long beam had to be ensured
as well as a certain elasticity that is described in this regulation:
"At a height of 1200 mm and with a testing load of 135 kg in the
middle of the beam it is ought to bend a maximum of 8 mm" (Book
of Norms, edition 1965, page 31). Such precise regulations highly guaranteed
uniformity for international competitions; everywhere in the world the
balance beam secured equal opportunities which is one of the basic laws
of any fair competition in Olympic artistic gymnastics. The acrobatic
coined gymnastics on beam challenged designing engineers as well as
people responsible of the International Federation of Gymnastics.
When somersaults and
free handsprings on beam became
increasingly standard, improvements of the beam had to follow as it
is stated in this demand, for instance: "The beam must have an
elastic overlay... In spite of a certain elasticity it has to ensure
a safe footstand and good balance. The sheath must be tearproof as well
as grippy and firmly fixed to the beam" (Book of Norms by FIG).
In 1974 only "safety of footstand" was mentioned, but in 1979 this safety is defined more precisely: Then it says: "...To prevent injuries after falls the surface must be designed to give in at least 5 mm at the maximum loading capacity at the point of load incl. edges". The risk of injury is explicitly mentioned: "The ends must be padded to prevent injuries.

Rhodesian Air Force Operations
This is the memoirs of a combat pilot that survived the Rhodesia-Zimbabwe War _PHONE_. This book records the operations of the Rhodesian Air Force. It includes a log of over 1145 airstrikes carried out as well as maps where most of these have been meticulously plotted. The maps are in full colour and numerous photographs illustrate the text. To those historians and collectors of militaria, this book is one that fills in much detail. It is a comprehensive account of the Rhodesian Air Force role in the war in Rhodesia - and is one of the most detailed summaries of Rhodesian military operations to have been published. In this respect it serves as an excellent work of reference.

We are importing (Bulk Insert) of around half million records to the staging table and then to the production table.
More often column data type or size validation fails the bulk insert process from Staging table to the Production table.
I will have to redesign the process by SSIS packages by inserting all the good records from Staging to the Production and load the bad / error out data to the staging table. Those bad or error out data with proper validation message.
Validation message is based on first error out column. If the all the columns in that row are erroring, we can consider with the first column error and reload the data after fixing that data.
Example Error Message: Column PurchaseDate has invalid data
How do I achieve this complete workflow SSIS package. What are the controls, I need to use to start with?

Effect of wet- and dry-grind fly ash on the durability of concrete
This paper presents a series of experimental studies on the durability properties of concretes containing wet-grind and dry-grind fly ash. The durability performance of fly ash concrete was assessed from measurements of compressive strength, drying shrinkage, chloride permeability, seawater corrosion resistance and pore structure tests. Results show that the wet-grind process narrows the particle size distribution range of fly ash and controls the particle size distribution. The durability of fly ash slurry concrete was shown to be improvable compared to dry-grind fly ash concrete.
Currently, concrete is the most widely applied material in infrastructure construction. The durability of concrete is one of the most important construction performance parameters with complex effects regarding service life enhancement . Due to the fact that the cement production process consumes huge amounts of energy and that cement production involves greenhouse gases emissions, supplementary cementitious materials have been attracting the attention of researchers over the last few decades.
Fly ash and slag, the most common supplementary cementitious materials, can enhance...

Our high-energy dog is about one year, and has learned quite well not to jump on us adults when we come home. She does however, continue to jump up on our 6 year old daughter.
It's difficult for our daughter to ignore this, as we did, especially when the dog scratches her to get her attention. Is there another trick a child can use to stop a dog from jumping and clawing? It's hard for our little girl not to squeal and run when she gets gouged with the claws.
Dear Lulu's mom,
Let's go through what you've written, and determine what is known and what you have:
- A young, high-energy canine.
- An excited, happy-to-see-her-family canine.
- An animal that is genetically programmed to greet others (of any species) by jumping up.
- A young human child who inadvertently rewards the canine by squealing and behaving similarly to "prey", or at least acts as excited and happy as the dog.
- An excited, exuberant, happy, young energetic dog that has learned to discriminate really well: She greets adult humans in a manner they like while approaching the little ones in a contrary fashion.
Now, allow me to identify what you would prefer:
- For your dog Lulu to greet young children politely, as she does adults.
I have to say, there are no "tricks" or anything else magical that would stop your dog from jumping and clawing, but there are some definite training steps you could take to achieve your goals.
- First and foremost: decide what you want from your dog. You say "stop jumping." Okay, I know what you don't want, but what is it you DO want? You'll need to choose the behavior you want from your dog – this way, you'll know what to reward her for. You need to give her the "right choice" to make.
I myself, as both a certified professional dog trainer and regular "dog mom," I prefer to have dogs greet humans with either a "Sit to Greet," or if the dog is really excited, "Four on the Floor" (all four paws need to be on the ground). Both are simple behaviors that are easy to teach dogs. You just need to decide on which one would work best. I would say teach both. This way, depending on Lulu's state of mind, you can set her up for success. Four paws on the floor is easier and more realistic during those times when she is super-excited!
Now that you're able to focus in on what you want from Lulu, what is the best plan? The following steps should help guide you:
- Have you, and any other adults do some "dress rehearsals" of sitting to greet (or four on the floor), when you come home. You enter the room, ask for the "right behavior," reward with food, petting praise. Repeat this exercise enough times to where Lulu appears bored – or starts offering the behavior before you ask.
- Once Lulu is "getting it" with you, attach her to her leash (to help manage your environment), and practice having her sit-stay with your daughter along side of you. Make sure there is enough distance so Lulu can't pummel her, but close enough to help mimic the end position of "coming home and greeting."
- You and your daughter can repeat the "sit-stay" exercise in a few locations indoors. (Fewer distractions make it easier for Lulu). Each time, follow it up with yummy food treats and attention. Lulu learns: "My tushy on the floor makes the little human say "Hi" scratch my chin, and give me treats."
Add in having your daughter enter the house/room while you continue to manage her on leash. Once your daughter enters, she can ask Lulu to sit for greeting and food rewards.
If Lulu decides she'd rather jump up to greet, you can give her a "Too bad," and a "Time out!" Meaning, take her out of the room for about 20 seconds or so. This way, Lulu learns: "If I jump up, I get nothing! Plus, I get ignored and no attention whatsoever! Well that downright stinks! I think I'll do more sitting. It's a better outcome."
Additional dog training tips would include:
- Continue to practice step number 4, while changing locations within your house – back door, front door – and at different times of the day.
- Recruit "volunteers": ask if any of your daughter's friends are willing (obtain parents permission first). They can help you by being the "greetee." The more practice Lulu gets, the more she'll be able to generalize amongst humans of all ages and sizes.
As a final note, it sounds like the adults have been consistent in teaching Lulu what is wanted, which is great – this proves that she is paying attention and can learn what is asked of her. Your daughter on the other hand, because of being young herself, hasn't been able to refine her "ignoring" skills, or train Lulu to greet nicely. Because of the inconsistency, she has inadvertently made this undesired behavior stronger. So, when you're not training or teaching, manage the situation by being around to help prevent Lulu from jumping up.
The more consistent and structured your training plan is now, the quicker Lulu will "get it", which will result in polite greetings all around, long before your daughter heads off to college.


[[TOC]] = !DataTables = == Introduction == Sahana Eden uses the !JavaScript library !DataTables _URL_ to display results returned from the database. The !DataTables library provides a lot of properties and functions that customise the table that is produced. Sahana Eden doesn't expose all of the functionality that is available within the !DataTables library this makes it easy to get !DataTables up and running and it also ensures a consistent look and feel. However, it is possible to customise the !DataTables through the Sahana Eden framework. == Properties == A number of properties are set by the framework and rarely need to be changed. These have been marked in the following table as '''auto'''. Some properties are set with a default value, the default value (and where it is set) is indicated in the table below: ||= Eden Name =||= Purpose =||= Value =||= Remarks =|| || dataTableSelectable || If set this allows the rows to be selected. || Boolean || This is set up as a property of response.s3 || || dataTableSelectAll || Only works if dataTableSelectable is set to True. The default is no elements are initially selected, by setting this to True all elements will initially be selected. || Boolean || This is set up as a property of response.s3 || || dataTableSelectSubmitURL || Only works if dataTableSelectable is set to True. This is the URL to which the submit button will send the selected details. || Boolean || This is set up as a property of response.s3 || || dataTablePostMethod || Only works if dataTableSelectable is set to True. The default mechanism is to send the details of the selected elements as part of the URL. If this is set then the details will be sent as a POST. However this does require a form to be wrapped around the dataTable. || Boolean || This is set up as a property of response.s3 || || actions || The list of action buttons to be displayed in the first column. The default action is to send a command to the server a new _jqclick option will attach some java script to the button rather send a request to the server. || List of actions. Each action is a dictionary values. And consists of the label, the HTML class and the URL. Optionally it may also include a restrict list that restricts these buttons to being displayed to just the ids on the list. || This is set up as a property of response.s3 || || dataTableID \\'''auto''' || The HTML id that will be used to identify this table || String \\'''default value''' 'list' || Set up using s3mgr.configure in the pre-processing || || dataTable_iDisplayLength \\'''auto''' || The number of rows to be displayed on a page || Integer || ''Confusion...'' dataTable_iDisplayLength and iDisplayLength || || no_sspag \\'''auto''' || This will turn off pagination || Boolean || Pagination is the default and nothing needs to be done to enable it. || || sortby || This will do an initial sort on the selected column or columns || list of sorting rules. The sorting rules are a list that comprises of the column number followed by the sort direction ||default value ![[1,'asc']] if this is changed then you also need to use the orderby attribute which is used to order the records coming off from the database.|| || dataTable_sDom \\'''auto''' || This defines where the controls of the !DataTable will be positioned || String explained in the !DataTables documentation || default value 'fril<"dataTable_table"t>pi' See _URL_ for more information || || dataTable_sPaginationType || This defines what controls are displayed to allow the user to page through the records || String either 'two_button' or 'full_numbers' \\'''default value''' 'full_numbers' || || || dataTableDisplay || This can be used to change how a cell displays the text || List of translations. Each translation is a dictionary item and consists of the column number, the value to look for and its replacement || || dataTableStyleDisabled || This can be used to give a style to represent disabled text || list of ids to apply this style || This adds the class 'disable' to the tr element || || dataTableStyleAlert || This can be used to give a style to represent an alert condition for the row || list of ids to apply this style || This adds the class 'alert' to the tr element || || dataTableStyleWarning || This can be used to give a style to represent a warning condition for the row || list of ids to apply this style || This adds the class 'warning' to the tr element || == Examples == The following example illustrate how to implement dataTables in your code. It uses the following base code: {{{ #!div style="font-size: 80%" Model code snippet: {{{#!python resourcename = "csv" tablename = module + "_" + resourcename table = db.define_table(tablename, Field("name", required=True, notnull=True), Field("path", type="upload", uploadfield=True, required=True, notnull=True), comments(), migrate=migrate, *(s3_timestamp() + s3_uid())) table.name.comment = DIV(_class = "tooltip", _title = T("Name") + "|" + T("Enter a name of the CSV you are uploading.")) s3.crud_strings[tablename]= Storage( title_create = T("Upload a CSV file"), title_list = T("List of CSV files uploaded"), label_list_button = T("List of CSV files"), ) }}} Controller code snippet: {{{#!python def csv(): """ RESTful Controller """ module = "importer" resourcename = "csv" tablename = module + "_" + resourcename table = db[tablename] # Pre-processor def prep(r): if r.interactive: s3mgr.configure(r.tablename, deletable=True, addbtn=True) return True # Post-processor def postp(r, output): return output response.s3.prep = prep response.s3.postp = postp return s3_rest_controller(module, resourcename) }}} }}} This is sufficient to generate a vanilla dataTable as follows: [[BR]] [[Image(DataTable_Plain.png)]] [[BR]] === Adding Buttons === With the default settings two buttons are provided, Open and Delete. Additional buttons can be added by using the actions, or more fully, response.s3.actions. The following code will add an "Import" button. {{{ #!div style="font-size: 80%" Add this to the postp() function of the controller: {{{#!python def postp(r, output): s3_action_buttons(r) response.s3.actions = \ response.s3.actions + [ dict(label=str(T("Import")), _class="action-btn", url=URL(c=module, f=resourcename, args=["[id]", "import"]) ), ] return output }}} }}} Notice that before the Open and Delete buttons were provided, now they need to be explicitly added with the call to s3_action_buttons(r), this will also perform the correct permission checks. [[BR]] [[Image(DataTable_Plus_Import_Btn.png)]] [[BR]] === Adding Buttons conditionally === Maybe you don't want the ability to import every file. Such as files that are older than a certain date. Also actions can be (and should be) restricted to the users permissions. For more example on how to apply restrictions to a users permissions see the code for s3_action_buttons() in models/00_utils. {{{ #!div style

Background: In the United States, over 1,650,000 new cases of cancer are being diagnosed yearly with almost 50 % of them being the top five bone-seeking cancers. Since cancer risk increases with age, this suggests that orthopedic oncology services may be a strain on the Medicare system. The femur is the most common site of long bone metastases. Prophylactic fixation techniques prevent pathologic fractures, reduce morbidities, and enhance the quality of life of patients with femoral metastases. This study aims to assess the rate of metastatic disease to the skeleton and evaluate the use and financial burden of femoral prophylactic fixation techniques on the Medicare system.
Questions/purposes: (1) In the Medicare population, has the number of skeletal metastases increased? (2) In the Medicare population, has the use of prophylactic fixation techniques increased? (3) How has the financial burden of prophylactic fixation changed over the study period?
Methods: The Medicare database was searched between 2005 and 2014 with the assistance of PearlDiver Technologies Inc. and the RBRVS DataManager Online from the American Medical Association. Searches were completed by using International Classification of Disease-9 (ICD-9) and current procedural terminology (CPT) codes for secondary malignant neoplasms and prophylactic fixation techniques. Facility charges, Medicare reimbursement and length of hospital stay were extracted from the Medicare database. Simple linear regression was performed to test the significance of yearly changes and the coefficient of determination was used to assess the strength of the correlation.
Results: (1) In the Medicare population, has the number of skeletal metastases increased? While the number of Medicare patients with skeletal metastases has increased from 132,452 in 2005 to 155,819 in 2012 (p = 0.01, r2 = 0.72), the prevalence of skeletal metastases in this population remained constant at 30.66 cases per 10,000 Medicare patients in 2012 (p = 0.56, r2 = 0.06). (2) In the Medicare population, has the use of prophylactic fixation techniques increased? The number of prophylactic fixation techniques has not increased from 2005 to 2014 (p = 0.68, r2 = 0.02); however, the rate of prophylactic fixation among those diagnosed with skeletal metastases has significantly decreased from 94.6 per 10,000 in 2005 to 82.72 per 10,000 in 2012 (p = 0.006, r2 = 0.74). (3) How has the financial burden of prophylactic fixation changed over the study period? Both total and average hospital charges increased after adjusting for inflation in the total Medicare population; however, only the average Medicare reimbursement changed to reflect this. The total amount Medicare spent on prophylactic fixation techniques in 2012 was $20,245,957 after adjusting to 2014. Despite the increase in hospital charges and average Medicare reimbursement, the average length of hospital stay in the total Medicare population showed a significant decreased trend-down from 7.51 days in 2005 to 5.86 days in 2012 (p = 0.02, r2 = 0.81).
Conclusions: Although the prevalence of metastatic disease to the skeleton remained stable between 2005 and 2012 in the Medicare population, prophylactic femoral fixation techniques declined in elderly adults between 2005 and 2014. This most likely signifies an increase in other treatment modalities that can prevent pathologic fractures such as prophylactic hemiarthroplasty, bisphosphonates, and/or radiation therapy.
Level of evidence: Level IV, Cross-sectional Study.

The Forières wind farm consists of four wind turbines with a capacity of 2 megawatts (MW) each. It is RWE Innogy's third wind farm in France besides the wind farms Petit Caux and Hauts Traits. Additional wind farms are planned in the regions of Pays de la Loire, Normandy and Midi Pyrénées.
By commissioning the Forières wind farm, RWE Innogy increases its French wind energy portfolio to 28 MW. Moreover, the company runs hydroelectric power plants with a generation capacity of 45 MW in France.
Approx. 3.4 gigawatts (GW) of wind power capacity were in operation in France at the end of 2008. 5.6 TWh of electricity were generated from wind power in the year as a whole. This is equivalent to a share of 1.2 % of France's total electricity consumption. By 2020, the installed wind power capacity is to grow to 25 GW of which onshore plants and offshore facilities are to account for 19 GW and 6 GW respectively. Power generation from renewable energies is financially supported by guaranteed payments for electricity fed into the grid.
RWE Innogy is the company for renewable energies in the RWE Group and invests an average of at least 1 billion euros per year in the development of power generation from renewable energies. In the focus are in particular wind, water and biomass projects in whole Europe. With a capacity of some 1.4 GW, the company ranks among Europe's leading wind power producers. RWE Innogy has a total installed capacity of 2.1 GW. The company intends to increase its installed power plant capacity in operation or under construction to 4.5 GW by 2012.

Why Does My Subwoofer Make a Popping Noise?
A popping noise from the subwoofer indicates a power mismatch in the circuit. The popping noise occurs as the amplifier tries to produce more voltage than it can to meet the demands of the subwoofer. This ends up clipping the sound on every cycle.
A power mismatch is not the only issue that causes a popping noise from the subwoofer. The noise may also be due to loose connections in the circuit.
To fix the error, check that the power outage from the amplifier matches the subwoofer's RMS. The amplifier producing much less power than it should could be clipping the subwoofer, but also check if it's producing more power than the subwoofer can handle. More RMS power from the amplifier gradually heats up the voice coil and may burn it out. A solution to this is getting a condenser that's used to steady the power and transmit it out in stable currents.
A loose connection may also exist in the wire connections to the amplifier, voice coil or in the subwoofer itself. Carefully check all these wires and ensure that none of them are loose or melted away. Wires connecting the speaker cones and voice coils should also be checked and tightened.

FORT MYERS, Fla. — Some of a pregnant turtle's eggs started hatching after she was hit by a car and died in Fort Myers.
On November 11, the Common Snapping Turtle was admitted to Clinic for the Rehabilitation of Wildlife (CROW) with severe head trauma and upon admission, she was unresponsive.
The turtle was examined by veterinarians who found she was carrying eggs. She, unfortunately, did not survive her injuries.
The veterinarians were able to remove her eggs and began incubating them in hopes they would still be living.
The first hatchling emerged on February 15, followed by two others on February 16. Approximately 12 eggs are still in the process of hatching, according to CROW in a Facebook post.
Turtles often have to cross the road to lay their eggs, so drivers are strongly urged to begin braking if they see them on the road.

How to sort the words alphabetically in List?
Given List:-
['Zuba', 'Alpha', 'Beta', 'Thor', 'Gama', 'Tony']
Answer: You can use the sort() or sorted() python function for sort lists alphabetically in python.
 - sort() function – will modify the list it is called on.
 - sorted() function- will create a new list containing a sorted version of the list it is given
Example of sort list alphabetically in Python
Using sorted() Function
If you have a list of strings. You can sort it like this:
list1 = ['Zuba', 'Alpha', 'Beta', 'Thor', 'Gama', 'Tony']print(sorted(list1))
Output:
Python sort list (Array) Alphabetically
Note: If words that start with an uppercase letter get preference over those starting with a lowercase letter. If you want to sort them independently, do this:
sorted(list, key=str.lower)
You can also sort the list in reverse order by doing this:
sorted(lst, reverse=True)
Using sort() Function
ListName.sort() will sort it alphabetically. You can add reverse=False/True in the brackets to reverse the order of items: ListName.sort(reverse=False)
list1 = ['Zuba', 'Alpha', 'Beta', 'Thor', 'Gama', 'Tony']
list1.sort()
print(list1)
Output: ['Alpha', 'Beta', 'Gama', 'Thor', 'Tony', 'Zuba']

The use of drones in Pakistan normally brings to mind images of US spy planes attacking tribal areas. But drones now are being used to capture a different kind of picture in the country—showing some of the world's highest mountains being scaled by world-class climbers through some of Earth's thinnest air. While drones have long been the domain of the American military, civilians are now using them more and more to shoot ground-breaking footage of adventure sports.
This summer, for example, a Swiss expedition used remote-controlled helicopters to shoot rare footage of climbers on the Karakoram, one of the world's most demanding and formidable mountain ranges. The drones weight just a few pounds and cost between $1,000 and $40,000, a fraction of the size and cost of the standard helicopters traditionally used in adventure photography. Newer models tend to have all of their rotors facing into the sky, making them look a bit like a mechanical flying spider or insect.

Authors: Monfared, Y.K and Matencio, A. University of Turin.
Recently, prof. Francesco Trotta group of the University of Turin has published two studies where two different charged (anionic and cationic) Hyper-Branched Cyclodextrin-based polymers have been used for blood anticoagulation and pDNA transfection, respectively [1,2].
- In the first one and using a previously published material , the research group studied the polymer's intrinsic capacity to chelate calcium, using this as an anticoagulant agent . The synthesized material (using Pyromellitic anhydride, called HBCD-Pol in the paper) presented an anionic charge that can form a chelate. Although the chelation strength was lower than EDTA, the effect on coagulation was higher in comparison. This anticoagulation effect was studied in vitro and in vivo, giving the same profile, possibly due to the complexation of additional factors of the coagulation pathway.
- Additionally, a cationic hyper-branched polymer (using choline as a cationic unit, called Ppolly in the paper) was an excellent transfection promoter of plasmid in 2D and 3D cell cultures compared to lipofectamine. The material was tested for the first time in a biological application without relevant cytotoxicity.
Remarkably, these works open an interesting range of bioapplications with charged cyclodextrin polymers. They are not only able to complex biomolecules or macromolecules, but also to get intrinsic bioactivity.

On the number of essential arguments of homomorphisms between products of median algebras
- 19 Downloads
In this paper we characterize classes of median-homomorphisms between products of median algebras, that depend on a given number of arguments, by means of necessary and sufficent conditions that rely on the underlying algebraic and on the underlying order structure of median algebras. In particular, we show that a median-homomorphism that take values in a median algebra that does not contain a subalgebra isomorphic to the m-dimensional Boolean algebra as a subalgebra cannot depend on more than \(m-1\) arguments. In view of this result, we also characterize the latter class of median algebras. We also discuss extensions of our framework on homomorphisms over median algebras to wider classes of algebras.

Program to print N minimum elements from list of integers
Given a list of integers, the task is to generate another list with N minimum elements.
Examples:
Input: {23, 1, 6, 2, 90}
Output: {1, 2}
Input: {34, 21, 56, 42, 89, 90, -1}
Output: {-1, 21}
Approach: The idea is to use the concept used in Find the smallest and second smallest elements in an array.
 - First, find the smallest number in the given list.
 - Then add that current minimum element to another list that will contain the N minimum elements.

Maximum vertical discharge height for water flow from vertical oriented pipe or tube:
Vertical Discharge - Imperial Units
- coefficient k = 0.96
Vertical Discharge - Metric Units
The maximum height for water discharge from vertical pipe can calculated as:
h = (Q / (5.68 k d2))2 (1)
h = discharge height (inches)
Q = flow (gpm)
k = coefficient ranging 0.87 - 0.97
d = diameter of pipe (inches)
- 1 in (inch) = 25.4 mm
- 1 gal (US)/min = 6.30888x10-5 m3/s = 0.227 m3/h = 0.06309 dm3(litre)/s = 2.228x10-3 ft3/s = 0.1337 ft3/min = 0.8327 Imperial gal (UK)/min
Measuring Flow - the Trajectory Method
The discharge from a vertical oriented pipe can be calculated by rearranging eq. (1) to
Q = 5.68 k d2 h1/2 (1b)
The challenge with this flow measurement method may be to measure the height h.
Example - Measuring Flow by measuring the Discharge from a Vertical pipe
The discharge height from a vertical oriented 4 inches pipe is 3 ft (36 inches). With a coefficient k = 0.97 the flow from the pipe can be estimated to
Q = 5.68 0.97 (4 in)2 (36 in)1/2
= 529 gpm

Q: Should blood tubing be primed with or without normal saline before administration of blood products?
A: Christine Kessler, RN, MN, CNS, ANP, BC-ADM, replies:
Many hospital transfusion protocols and related nursing practices have been based more on tradition and assumptions than on scientific evidence. The saline priming of blood transfusion tubing is one such nursing practice that has long been guided by tradition. The risks and cost related to transfusion therapy have spurred a great deal of scientific inquiry in the past 15 years.
Approximately 15 million blood and blood component transfusions occur annually within the United States, making it a common lifesaving and life-sustaining intervention, especially within intensive care, surgical, and trauma units. Various estimates indicate that between 15% and 45% of patients require transfusions during their intensive care unit (ICU) stay, depending on their length of stay.1,2...

The Wisconsin Natural Resources Board recently approved a set of rules designed to address phosphorous and other nutrient pollution, as well as help control erosion and sedimentation in the state. Wisconsin farmers will be able to obtain up to 70% of the costs of implementing non-point pollution controls to meet the standards set by the new rules, according to the Wisconsin Department of Natural Resources (DNR)
The rules address both point and non-point sources of pollution, including agricultural sources, factories, municipal water treatment systems, and urban and suburban storm water runoff. Science-based, numerical water quality standards for phosphorus have been established.
"This comprehensive approach means that we will identify and work proactively with all sources that contribute to poor water quality in a watershed. We will rely on solid data to take actions that achieve maximum environmental benefits in the most cost-effective manner possible. These rules strike a good balance between creating a solid path to cleaner water and providing flexibility in implementation," says Matt Frank, Wisconsin Department of Natural Resources Secretary.
Included in the package are numeric water quality criteria for rivers, streams and lakes that are expected to prove pivotal in determining phosphorus levels to keep waters clear of algae and safe for recreational activities. Wisconsin has 172 lakes and streams on the impaired waters list for phosphorus. Frank says that with this package, Wisconsin becomes the first state in the country to create these water quality standards for rivers, lakes and streams.
The rules build on Wisconsin law that requires the state to partner with the agriculture community and provide cost-sharing dollars. The Wisconsin DNR will work with county land conservation experts and farmers to help them use the best management practices to curb pollution, while helping provide incentives toward cost-effective solutions. Under this provision, the DNR will provide the cost-share program as part of a positive enforcement of the rules.

The cooling rate of the liquid oxide can be controlled in industrial sintering processes through the draft pressure and has the potential to influence microstructure formation. The solidification of a liquid within the hematite primary phase field in the ternary "Fe2O3"–CaO–SiO2 system in air was undertaken at different cooling rates to determine the impact of cooling rate on the formation of product microstructures. Samples with a bulk composition of 72.7 wt% Fe2O3 and a CaO/SiO2 ratio of 3.46, were cooled from 1623 K (1350°C) at 2 K/s, 0.5 K/s, 0.1 K/s and 0.01 K/s and quenched at 5 K temperature intervals from 1533 K (1260°C) to 1453 K (1180°C). During cooling, four stages of phase assemblage formation were consistently observed at all cooling rates; in order of formation these are, Liquid+hematite (I), Liquid+hematite+dicalcium silicate(C2S)(II), Liquid+C2S+calcium diferrite (CF2)(III) and C2S+CF2+calcium ferrite (CF)(IV). An intergrowth of silico-ferrite of calcium and aluminium-I (SFCA-I) and Ca7.2Fe2+0.8Fe3+30O53 was observed to form in some conditions in regions free of hematite, present in liquids solidifying at 0.5 K/s and 0.1 K/s. The sizes and shapes of microstructures were observed to systematically change with cooling rate, with a slower cooling rate typically resulting in coarser coupled microstructures and larger individual crystals. A larger proportion of coupled microstructures are observed at slower cooling rates, this appears to be related to the degree of undercooling prior to the nucleation of new phases. The equilibrium silico-ferrite of calcium (SFC) phase was not observed at any of the cooling rates investigated.

Netflix has created its service that is streaming-video to setup simple and simple. The method involves two fundamental steps: produce an online account and introduce the software in your streaming "stick," set-top package or smart television. Although setup involves several other details, like the quality associated with connection that is internet in many circumstances, you could have Netflix ready to go in moments.
Use the internet to www flix and put up an account; then load the Netflix application on the streaming "stick," set-top field or smart TV and enter your bank username and passwords.
Produce a Netflix Account
Begin a web browser up on your own favorite Computer, Mac or smart phone. Go right to the web site, www flix , and stick to the instructions to generate a merchant account. Your website will ask you for a message target to validate your recognition and a repayment technique such as for instance a credit or debit account quantity. Select the known standard of solution you would like and submit the web application.
Check Always Web Connection
Make fully sure your television is internet-enabled, either by having a wired Ethernet or Wi-Fi connection. Additionally, the text rate is essential. Netflix suggests a information install speed of at minimum 3.0 Mbps for standard-definition (SD)-quality movie. For high-definition (HD) content, you will need 5.0 Mbps, and ultra high-definition requires 25.0 Mbps.
Select or Install Netflix App
When you have A tv that is smart look at factory-installed apps to see if Netflix has already been available; TVs from many manufacturers includes the Netflix application. In the event that you do not view it, stick to the maker's directions to down load the Netflix software and install it. Introduce the software, and it surely will prompt you for the e-mail target and password you utilized to generate your account.
In really unusual circumstances, your TV's that is smart software be incompatible utilizing the Netflix application. You may need certainly to change the television with a more recent model or update its pc software.
It _URL_ is possible to view Netflix on a regular television by having an HDMI connector by plugging in a streaming "stick" such as for instance Amazon Fire Stick, Bing Chromecast or Roku, or even a set-top field such as Apple television, Amazon Fire television or one from a satellite/cable television provider. The device will have the Netflix app pre-installed in most cases. Set up the app along with your username and passwords and also you're ready to stream movie.
View Streaming Video
With all the account put up and also the software operating, look at movie content making use of your television's remote to navigate the Netflix interface. Once you decide on a profile, the Netflix software displays Releases that isвЂњNew, вЂњNetflix OriginalsвЂќ and a number of other groups. While you browse and watch content, the Netflix pc software вЂњlearnsвЂќ your requirements and makes suggestions centered on your watching history.
Streaming on Other Devices
Utilising the exact same Netflix account as the only on the television, you are able to stream movie content to many PCs, laptops and mobile phones. For PCs and laptop computers, make use of a appropriate web browser such as Bing Chrome, Apple Safari or Mozilla Firefox. For cellular devices, download the Netflix software from your own unit's app store.
Optional: Parental Controls
Start thinking about establishing the Netflix account's controls that are parental avoid content that clients or workers might feel is objectionable. Making use of your account's 4-digit PIN quantity, you are able to produce a number of audience pages, all of that has unique maturity that is content settings.

Merge partitions Server 2019
Merge partitions and Unallocated space in Windows Server 2008
To manage disk partitions and use disk space more efficiently, you need to do many operations, for example: delete an unused partition, format a partition to rebuild file system. Sometimes you need to shrink or extend a partitioned drive, decrease or increase the number of drives. In this article, I'll introduce how to merge partitions and combine Unallocated space in Windows Server 2008 R2.
Merge partitions Server 2008
How to merge partitions
By merging partitions, there are two benefits: transfer free space from a drive to the other one that is running out of space and decrease the number of drives.
 - Transfer free space
Some drives such as system C drive and the drives for backup and projects are very likely running low on disk space. In this case, you can increase free space by merging other drives. For example: by merging volumes E to D, the free space in E will be transferred to D. So you can solve this problem without starting over or waste a long time to back up and restore.
 - Decrease number of drives
As we know, it is better to create more volumes to save different type of files, so you can better organize and locate the files. But on the other hand, if you create too many drives, each drive is smaller, and it may cause difficult to find the files you need.
Steps to combine partitions in Windows Server 2008 R2:
1. Download NIUBI Partition Editor and you'll see all disk partitions.
Merge partitions server 2008
2. Right click either drive D or E and select Merge Volume.
3. In the pop-up window, click the check-box of both D and E, and then click the drop-down box to select destination drive.
Select volumes
Click OK and back to the main window, drive E is combined into D drive, click Apply on top left to execute, done.
Partitions merged
Open drive D when partition merging complete, a new folder is created as E to D(with date and time), all files in drive E are moved to this folder automatically.
Files moved
Note:
 1. Do not merge partitions C and D, otherwise all programs and services in D become invalid, though you won't lose these files.
 2. It is not suggested, but you can still merge C and D drive with NIUBI. However, to avoid system boot failure, you can only combine partition D into C. Merging drive C to D is disabled.
Merge C and D drive
How to merge Unallocated space
Besides creating new volumes, Unallocated space can be added into to a partitioned drive, then this Unallocated space will be converted to part of the free space in this drive.
In Windows Server 2008, you can get Unallocated space by deleting or shrinking a volume in its native Disk Management. You can also combine Unallocated space with the built-in Extend Volume functionality, however, you can only merge this Unallocated space to the drive that is adjacent and on the left side.
With NIUBI Partition Editor, you can merge Unallocated space to any volume in the same disk by simply dragging on the program.
Steps to merge Unallocated space in Windows Server 2008 R2:
For example: there is 20GB Unallocated space between drive C and D, let's see how to merge Unallocated space to C drive.
Merge Unallocated space
Right click C drive and select Resize/Move Volume, drag the right border towards the right.
Extend Unallocated to C
Unallocated space will be combined to C drive.
Unallocated merged
If you want to merge the Unallocated space to drive D: right click D and select Resize/Move Volume and then drag the left border towards the left.
How to merge nonadjacent Unallocated space
As you see, it is very easy to combine Unallocated space to any adjacent volume, you just need 1 step to drag either border towards the other side. To merge Unallocated space to nonadjacent volume, you just need 1 more step to move partition.
For example: there is a 20GB Unallocated space between drive D and E, let's see how to merge this Unallocated space to C drive.
Unallocated space
1. Right click drive D and select Resize/Move Volume, drag the middle position rightwards.
Move Unallocated
Unallocated space will be moved to the left side.
Unallocated space moved
2. Right click drive C and select Resize/Move Volume again, drag the right border rightwards to combine the Unallocated space.
No matter you want to merge partitions or merge Unallocated space in Windows Server 2008 R2, it is very with NIUBI Partition Editor by simply dragging on the program.

that has the same method name and a compatible method signature and it will execute just that one method. Every other method after the first method found will simply be ignored.
Points of Interest
Bypassing Sealed Methods and Types: "Duck Taping"
One problem that has dogged many developers when using various class libraries is when the given library author seals a type and prevents its methods from being overridden. In normal circumstances (that is, in statically typed languages), this is akin to hitting a brick wall. Fortunately, this isn't the case with LinFu.DynamicObject. Generally, you can bypass a sealed type using the following steps:
Create (or Find) an Interface That Looks Like Your Target Type
The first thing that you need to do is figure out which methods or properties you will override in the target class. Then create an interface that is similar to the list of methods that you will be overriding. In this example, suppose that I wanted to override System.Data.SqlConnection so that I got a notification every time I called IDbConnection.Open(). Since all connections inherit from System.Data.IDbConnection (and, more importantly, they all look like IDbConnection), I can use that interface as the type I will be using for duck typing.
Wrap the Sealed Class Instance and Create the Duck
DynamicObject dynamic = new DynamicObject(new SqlConnection());
// Note that this action doesn't actually cast it to an IDbConnection;
// it just makes it *act* like one
IDbConnection duck = dynamic.CreateDuck<IDbConnection>();
Override the Duck
Next, we need to create an interceptor that wraps around the intended target method or methods. In this case, we want to wrap IDbConnection.Open():
public class CustomInterceptor : IInvokeWrapper
{
 private object _target;
 public class CustomInterceptor(object target)
 {
 _target = target;
 }
 public void BeforeInvoke(InvocationInfo info)
 {
 if (info.TargetMethod.Name != "Open")
 return;
 // Add the additional behavior here
 Console.WriteLine("Open Method Called!");
 }
 public object DoInvoke(InvocationInfo info)
 {
 // Call the original implementation
 object result = info.TargetMethod.Invoke(_target, info.Arguments);
 return result;
 }
 public void AfterInvoke(InvocationInfo info, object returnValue)
 {
 // Do nothing
 }
}
Once the interceptor has been defined, the next thing to do is create a proxy for IDbConnection. Then tie the duck and the CustomInterceptor together into one instance:
ProxyFactory factory = new ProxyFactory();
IDbConnection unsealed =
 factory.CreateProxy<IDbConnection>(new CustomInterceptor(duck));
// Once the Open() method is called, it will now print "Open Method Called!"
unsealed.Open();
...and that's how you unseal a sealed type.
Interceptor by Design
For those of you who use LinFu's DynamicProxy, one thing that you might find interesting is that DynamicObjects are interceptors themselves. This means that any DynamicObject can act as an interceptor for any proxy created by LinFu.DynamicProxy's ProxyFactory class. For example, suppose that I already have an existing proxy in memory and I want to create a dynamic interceptor so that I can attach it to the proxy:
ProxyFactory factory = new ProxyFactory();
IMath math = factory.CreateProxy<IMath>();
// Create the dynamic interceptor
DynamicObject interceptor = new DynamicObject();
// Attach it to the proxy
IProxy proxy = math as IProxy;
proxy.Interceptor = interceptor;
// Now the proxy is pointing back to the DynamicObject;
// This is where you would start dynamically adding methods
// to that DynamicObject
...
This approach makes it easy to incrementally build an interceptor implementation as the application is running. The possibilities are endless.
Using DynamicObject with C# 3.0
Another realm of possibilities opens up once you combine the abilities of LinFu.DynamicObject with the upcoming language features of C# 3.0. Some of these possibilities are:
Mixins Using Anonymous Types
Now that C# 3.0 has support for anonymous types, dynamically creating throwaway interface implementations is easy. Using an anonymous type, I can easily provide an implementation for IPerson by using the following code:
DynamicObject dynamic = new DynamicObject();
dynamic.MixWith(new {Name="Me", Age=18});
IPerson person = dynamic.CreateDuck<IPerson>();
// Print the name and age
Console.WriteLine("Name = {0}", person.Name);
Console.WriteLine("Age = {0}", person.Age);
Shorter Anonymous Delegates with Lambda Expressions
While in some ways, being able to write shorter anonymous delegates using lambda expressions is no more than syntactic sugar, using lambda expressions with LinFu.DynamicObject (in my opinion) makes the code a bit easier to read. For example, using the previous example with the MathOperation type, I can rewrite it using lambda expressions so that it looks something like:
public delegate int MathOperation(int a, int b);
public class Program
{
 public static void Main()
 {
 // Define the method body
 MathOperation body = (a, b)=> { return a + b; };
 // Create an empty DynamicObject
 // that wraps around a System.Object
 DynamicObject dynamic = new DynamicObject();
 dynamic.AddMethod("Add", body);
 // This will return '2'
 int result = (int)dynamic.Methods["Add"](1, 1);
 }
}
Saving Space
At first, saving yourself from typing a few characters doesn't seem to be a marginal gain in efficiency, but what if the IMath class were defined as:
public interface IMath
{
 int Add(int a, int b);
 int Subtract(int a, int b);
 int Multiply(int a, int b);
 int Divide(int a, int b);
}
What was once one small declaration has turned itself into four and you have effectively increased the amount of items you have to type by 400%. What if you had to type even more than that? Suffice it to say, once you've gotten past ten repetitive anonymous delegate declarations, you'll be well past the point of tedium. For the sake of simplicity, however, let's stick to the four operations mentioned above.
The next thing that I have to do is redefine all of the operations performed by the IMath class:
MathOperation add = (a, b) => { return a + b; }
MathOperation subtract = (a, b) => { return a – b; };
MathOperation multiply = (a, b)=> { return a * b; };
// Divide by zero check omitted for brevity
MathOperation divide = (a, b)=> { return a / b; };
Once again, in DynamicObject, I have to add the new methods and implement the interface:
DynamicObject dynamic = new DynamicObject();
dynamic.AddMethod("Add", add);
dynamic.AddMethod("Subtract", subtract);
dynamic.AddMethod("Multiply", multiply);
dynamic.AddMethod("Divide", divide);
IMath math = dynamic.CreateDuck<IMath>();
// Perform all of the operations
Console.WriteLine(math.Add(1, 1));
Console.WriteLine(math.Subtract(1, 1));
Console.WriteLine(math.Multiply(1, 1));
Console.WriteLine(math.Divide(1, 1));
As you can see here, being able to use lambda expressions in place of full-length anonymous delegate declarations can save quite a lot of time and typing. As for the rest of the code above, well, if you've gone this far into the article, then everything I mentioned above is practically boilerplate. It's almost as if dynamically adding methods were nothing new, but I digress.
Parsing LINQ Expression Trees
With LINQ coming up on the horizon, LinFu.DynamicObject naturally makes for a near-perfect expression tree visitor. Here's a simple (and hypothetical) example of a visitor using DynamicObject:
public class ExampleVisitor
{
 ...
 public void DoVisit(Expression expression)
 {
 // Let the DynamicObject decide which method to call
 DynamicObject dynamic = new DynamicObject(this);
 dynamic.Methods["Visit"](expression);
 }
 public virtual void Visit(MethodCallExpression expression)
 {
 // Do something useful here
 }
 public virtual void Visit(BinaryExpression expression)
 {
 // Do something useful here
 }
 ...
}
In this example, I wrapped

Two UW–Madison researchers build ties with Indonesia
It took a trip halfway around the world to bring two University of Wisconsin—Madison scientists together.
Paleoanthropologist John Hawks and climate scientist Dan Vimont had never crossed paths on the Madison campus due to their very divergent areas of study. But they landed on common ground at the Kavli Indonesian-American Frontiers of Science Symposium, held July 11-15 in Solo, Indonesia.
Co-organized by the Indonesian and U.S. National Academies of Sciences, the symposium brought together a mix of young American and Indonesian scientists from a range of fields — nanotechnology to earthquakes — to discuss globally relevant research and to foster collaborations between the two countries. The UW–Madison researchers were two of just nine U.S. scientists invited to speak.
The Frontiers of Science symposia have promoted connections between young scientists since 1989, with increasing importance placed on international relationships with scientists in Europe and Asia. The Indonesian-American symposium began in 2011 in response to the Obama administration's call for stronger ties with scientists in predominantly Muslim countries.
"The goal is to get people talking — to help Indonesian scholars develop their scientific infrastructure and to get more Americans involved who might have an interest in working there," says Hawks.
Vimont, a professor of atmospheric and oceanic sciences and a climate researcher in the Nelson Institute for Environmental Studies, discussed international food security in the face of changing climate, a critical concern in a country whose rice imports in a bad growing year can equal roughly a fifth of the total global rice market. Hawks, a UW–Madison anthropology professor, spoke about human evolution and genetic variation.
Both met potential future collaborators and came away with a stronger appreciation of the research needs and opportunities in Indonesia. In addition to the scientific sessions, the participants attended cultural events and local tours, and Hawks was able to spend a day at a nearby dig with an Indonesian paleontologist.
"I see science as a unifying theme for bringing people together," Vimont says. "These symposia are a piece of a broader effort to use science as a way to encourage development."
