Loud pop in knee followed by pain

Why do you get knee pain after hearing a loud noise from your knees? Pain following a loud noise heard from the knee can be due to rupture of the ligaments around the knee joint, if you want to know the cause of pain after a loud knee, If you want to know what are the symptoms of knee ligament rupture and what are the solutions to treat them, read more.

Introduction
Hearing a very loud sound from the knees, followed by severe pain, is one of the hallmarks and signs of a ruptured ligament in the knee joint.
These tears can occur during sports competitions, injuries and traumas to the knee. Often, small, limited tears in the knee ligaments can heal on their own. In general, 4 ligaments in the knee joint participate in the structure of the knee joint and cause stability and stability of the joint.

What happens when we hear a loud noise in the knee that is followed by severe pain?
If you have recently experienced severe pain in your knee following a loud knee injury, it could be a sign of a problem with your knee ligaments, meaning that a small part of your knee ligament may need to be surgically removed.
It could be due to a sudden rupture of the ligaments involved in the construction of the knee joint, or it could be due to a rupture and rupture of the knee meniscus.
Knee ligament is one of the hallmarks of knee pain when loud noise from the knee and subsequent severe knee pain follows. It can also be said that tearing the menisci of the knee can be accompanied by noise and pain and locking.
Knee locking is much more pronounced following a ruptured meniscus. When a meniscus ruptures, a piece of cartilage is broken and can get stuck in the joint space.

Familiarity with knee anatomy
It is better to study the functional anatomy of the knee to better understand the cause of hearing loud noise, which leads to severe knee pain.
The largest and most functional joint in the human body is the knee. This joint is composed of different structures.
Tendons and ligaments, the bursae and menisci and other components of the lower thigh and upper leg, as well as the patella, are the bones that make up the knee joint.
In general, there is an important point in the structure of the knee, and that is that in the lower part of the femur on the tibia, there should be hinged movements, and the location of the patella in the groove located in the lower and anterior part of the femur is very important, The patella moves up and down in the groove-like sunken mentioned above in the lower front of the femur.
Both the patella post and the outer surface of the lower sheath have cartilage
There are very strong ligaments in the knee joint that connect the bones. They prevent the bones involved in the structure of the knee joint from moving in any direction. The function of the ligaments is to facilitate and correct bone movement.
Knee ligaments will prevent the bones that make up the knee joint from moving abnormally.

What are knee ligaments?
The knee ligaments are:
 1. ACL anterior cruciate ligament
 2. Posterior cruciate ligament PCL
 3. Internal MCL internal ligament
 4. LCl external collateral ligament
The most important position that the knee ligaments allow the knee to move is in the direction of bending and straightening the knee. Of course, the knee may move slightly in other directions, but the main range of motion of the knee and the main type of knee movement is bending and straightening.
The collateral ligaments of the knee are located on either side of your knee joint. In fact, the external collateral ligament is located on the outside of the knee, causing the femurs and the tibia to connect.
The internal collateral ligament is located inside the knee, causing the bones in the inside of your femur to attach to the tibia.

What is the function of the knee ligaments?
Knee ligaments play a major role in maintaining knee stability, which is to prevent lateral movements of the leg relative to the femur.
This means that there are healthy ligaments around the knee joint that cause the knee to bend and straighten and move forward and backward, preventing the knee from moving to the sides.

How are knee ligaments damaged?
In this section, we want to say how the knee ligaments are damaged. In the first part, we examine the damage to the collateral ligaments of the knee.
Damage to the knee ligaments can occur in a variety of ways, often in the form of a strain, or sometimes the ligaments may be incompletely torn or completely torn.
And the lateral ligaments or internal collateral ligaments are more damaged in humans than the external collateral ligaments.
This means that in humans, the prevalence of internal ligament injuries of the knee will occur more than external ligaments.
But because the anatomy and structure of the outside of the knee is more complex.
 - External collateral ligament injuries
They are always associated with more complex injuries, and other knee structures are generally damaged along with external collateral ligament injury.
Injury to the knee ligaments is due to forces acting on the knee and deflecting the leg to either side, or due to forces acting on the knee and pushing the leg to the sides.
Another mechanism is that when a direct blow is applied to the outside of the thigh on the outside of the knee, it causes the surface of the knee joint to open more on the inside. Following this change, stretching of the internal collateral ligament occurs, and the injury can range from a stretch to an incomplete to complete rupture of the internal collateral ligament.
Another mechanism that causes damage to the internal collateral ligament of the knee is that the person standing on one knee bends the knee slightly, in which case the torso rotates on the knee.
In fact, in this case, you rotate your torso on your knees, these injuries are caused by this mechanism more in a group of athletes who do sports such as football, volleyball, skiing and basketball.
The pressures mentioned above with the mechanisms that are applied, if the force of the force is low, will only cause the ligament to stretch and sprain.
The most common injury to a human knee is a sprain and injury to the internal collateral ligament. If too much pressure is applied to these ligaments, it may go through a sprain, resulting in incomplete rupture and complete rupture.
If the pressure is increased, the cruciate ligaments as well as the meniscus of the knee will be damaged. The bones around the knee joint may also break.
 - Now let's see how the external collateral ligament of the knee is damaged
It is said that this ligament will be created by the blows and forces that are applied to the inside of your knee. The external collateral ligament is less damaged than internal problems in humans, but because there is a complex anatomy on the outside of the knee, Like the dorsal capsule of the knee, the cruciate ligament and even the peroneal nerve are damaged

What are the symptoms of lateral knee ligament injury?
The following symptoms occur when the lateral ligaments of the knee are stretched
There is pain in the sides of the knee, pain and tenderness will be felt on the affected ligaments and the pain is diffuse and unlike the pain caused by the injury and rupture of the meniscus which is concentrated in a small area, the pain of rupture of the ligaments is diffuse.
Following the rupture of the ligaments, the pain increases when pressure is applied to the injured area, that is, the pain increases when pressure is applied to the damaged ligament by hand.
Also during the examination, the doctor puts pressure and tension on the ligaments with special maneuvers, and during this time, the pain intensifies and the doctor finds out which side of the knee displacement has occurred.
Swelling is another sign of injury and rupture of the knee ligaments. When the injury is too great and the ligament is torn, a very loud sound will be heard, a very loud sound will suddenly be heard from the knee, followed by severe pain, followed by unstable knee.
There is some instability on examination, it may also bleed inside the knee, and the skin on the inner lateral ligament may turn blue due to bleeding.
In external tears, these events occur on the outside of the knee.

Diagnosis
It is said that the main diagnostic action by the physician is in fact the data and description that the physician should obtain from the patient's symptoms as well as the mechanism of injury and trauma.
The doctor should also perform special examinations of the patient's knee with his own sharpness in order to differentiate the injured ligament from other injuries.
And imaging examinations, imaging techniques such as plain X-rays of the knee and MRI of the knee, and diagnostic studies with arthroscopy can help the doctor make a diagnosis, and sometimes joint fluid aspiration and joint fluid analysis may be needed.

treatment
Lateral ligament injuries rarely require surgery
The important point is that if the injuries of Rano lateral ligaments along with the injuries of other knee structures are cruciate ligaments or meniscus of the knee, nerves and arteries, etc, surgery will be needed for treatment.

What is MyTalent™ Program?
MyTalent™ Program (hereto referred to as "the Program") is the most comprehensive online career and course advisory program for students in the age bracket of 14 to 21 years. The program has been designed and crafted in such a way so as to help students select their BEST-FIT subjects / courses / career on the basis of their aptitude, personality and interests.
The Program has been designed and built by expert counselors who carry with them a rich experience spanning over a decade in the field of education, applied psychology and human behavior. The counselors, having put in over 80,000 man hours and having counseled over 29,000 students, have carefully devised this program keeping in mind the Indian education set up and the Indian economic, cultural and social scenario.
The aim of the Program is to empower the student with complete knowledge about their inherent strengths, their aptitude, personality and interests, and help them get clarity about their most fitting and right career and course.
What is the Fundamental Premise of the Program?
The Program has been designed keeping in mind –
- Each student has got certain unique talents (aptitudes and personalities); just that most of us don't know about these talents or can't see / identify them in ourselves.
- A correct understanding of what is aptitude and what is personality will help one understand why they are so important in making right career decision.
- When a person chooses their course and career on the basis of their inherent strengths, or their inherent talent, or their aptitude, personality and interests, then it will help the student to naturally be able to enjoy their studies and their work, and ultimately, do well in their course / career, and thereby lead a happy and successful life.
- New age lifestyle diseases such as unhappiness at work, depression due to exam stress, exam failure, misery at work etc can be eliminated if students do NOT choose the WRONG course and career in the first place itself.
How does the Program work?
The Program will assess a student's aptitude, personality and interest over an approximately 2 hour long online assessment. This career assessment will include –
- Aptitude Test: approximately 30 minutes
- This test maps the "in-born" aptitudes of the student. These aptitudes naturally help the student to learn or do certain tasks or activities.
- For example: Certain students, right from their childhood would love to break open their toys and then reassemble back. This is indicative of a certain aptitude that is in-born.
- Personality Test: approximately 50 minutes
- This test maps the personality of the student, that is, it measures the most natural behavior that the student displays in different situations. It maps 28 personality traits.
- For example: There are certain students who are naturally extrovert, while others are shyer. There are a few, who are quick decision makers, while others who can analyze well.
- Interest Test: approximately 30 minutes
- This test maps the course / career interest of the student. The student explores around close to 200 different courses / careers, looks at all aspects and finally picks the one that he / she is most interested in.
- Parental Section: approximately 10 minutes
- We believe that parents play a very crucial role in a child's decision making. Therefore, this section will take in the parents' inputs, opinions and thoughts about their child.
What are the benefits of the Program?
- The Program works as a magical charm for students who are going through a phase of immense emotional, physical, and academic transition at this age. As if the worries of daily life were not enough, this additional worry of choosing the right course and career is also pressed on to the light-weight shoulders of a young child. On the one hand there is confusion because of many available lucrative careers; on the other hand, there are far too many influencers like the media, internet, and one's friends and family. The Program is aimed at helping all students from a practical, unbiased and neutral standpoint and helping them make the RIGHT decision regarding their course and career.
- Upon completion of the test and after payment of the package, every student gets two comprehensive reports, a MyTalent summary report and a MyTalent detailed report, that list their own aptitude, personality and interests along with a detailed information on these.
- The report consists of personalized career suggestions for each student. The counselors personally look into the report of each child, weigh it against the market situation, correlate it with the child's background, and offer suggestions of top three best suited careers for the child.
- The students get to understand the career suggestions for their unique combination of aptitudes and personality for them.
- On the basis of the report, the student will be able to get complete clarity on what are the right subjects / courses / careers for him / her.
- It will also help the student in chalking out his / her career goals and do proper career planning.
- The report not only offers suggestions for the right subjects / courses / careers, but also, it offers a complete career path / road map on the necessary steps a student must take in order to reach a particular career, including information on colleges, courses, entrances, and any other requirement / information needed by the student.
- Many students have reported scoring better results and a more focused approach after undergoing the Program and understanding oneself.
- The student becomes a part of the community that is self aware and moving forward with positive motivation in their lives.
- Depending on the package the students has purchased, the student can avail expert career counseling via email, phone or in-person. The career counselors will resolve all student queries and offer expert career guidance.
- The students get to explore various courses, entrance exams, colleges and careers and get in-depth information on them.
- The Program is even beneficial for parents as more often than not, it is the parents who are the most confused when it comes to helping their child choose the right career. Unlike in the past, when career options. were limited, students had to perforce pick those courses / subjects that helped in getting a secure government job. However, today, there are a plethora of lucrative career choices. The parents, though, are not too sure how to help their child pick the right career. That is precisely why; the MyTalent Program is of immense help for parents also.
- Parents also get to know about the inherent strengths, aptitude and personality of their child. This acts as a basis for taking academic, non-academic and career decisions.
- Parents also get to be a part of the email counseling / phone counseling / in-person counseling with the career counselors and get their doubts and queries resolved for their child's career.

For all entries in sap abap for 3 tables
At least one primary key field in the where class. It avoid the Nested Select Statement 4. Retrieve the data from more than one table.
This statement is used to replace select with joins. If we use more than three tables it puts heavy load on the Database, because the data has to be selected by comparing each table in the database server.
So it takes the long time for execution. This statement will never put load on the database. If ITAB1[] is not initial. Select F1 F2 F3…. Actually It is used instead of inner join because when we want to join morn than 3 tables using inner join it will put a heavy load on the database server. Post New Answer. I have developed a program where i have used Ranges and the program is running fine in DEV and Quality server but as soon as it goes to Prod server it shows some errors.
What can be done in this case?? What are the function modules that are generated when you activate a lockobject? In an Internal Table, I have records. I have to Retrieve One Record. In Performence wise what is the Best Query?
Is This Answer Correct? Anyhow, Answer 5 is excellent. Which of the following is not an exit command?In earlier blogs, I looked at various performance tuning techniques and tried to identify some that are more important than others.
A JOIN assumes that you want the data from more than one table. A sub-query assumes that you need data only from the main table. They are just for comparison purposes.
You can adjust the number of loop passes on the selection screen. SKIP 1. We will use this in comparisons. I ran it four different ways: with a single company code and document number, with a single company code and a range of document numbers, with a range of company codes and a single document number and with ranges of both company codes and document numbers. I ran the program a number of times in a 4.
I was a bit surprised at some of the results:. In the end, if you are interested in the differences for your particular case, then you must code different SELECTs to find which is best. One final thing to note: in the above program, the one SELECT that consistently underperformed was the one that did not use the index effectively. And that is the real point here. All of the techniques that I have shown here work reasonably effectively. The most important thing to remember is to use an index.
Rob Like 0 Former Member March 20, at pm I think much more reailistic results to compare the differences can be gained by selecting much larger sets of data. Try queries that search thru tables containing millions of records… Like 0 Former Member Post author March 21, at am Yes, I agree. I wanted to compare as many different methods as possible — including a sub-query. As I said in response to another question, I did some testing on joins using secondary indices that showed somewhat different results.
In another blog: Performance — what will kill you and what will leave you with only a flesh wound Performance — what will kill you and what will leave you with only a flesh wound I also used larger tables.
I believe the result also depends on the DB tuning. Best regards, Peter Like 0 Former Member Post author March 20, at am Thanks for the reply — yes, it certainly does depend on database tuning. Rob Like 0 Lars Breddemann March 20, at am How have the join conditions been supported by indexes on db-level in your tests? DBs heavily rely on additional structures that enable the efficient handling of Join-Selects.Lets see today Class based exception are more powerful compared to the "legacy" exceptions.
But you don't want to c By Naimesh Patel March 20, Performance 43, 3. The issue will happen when you have same posting for same GL using same CC in different periods. In that case, system would only bring one entry instead of the multiple. On the other hand the standard transaction would get you all the entries would a different total.
Than why my query wont work. You compare them and you would notice few entries are definitely missing. By the time, you are already expert in Excel. Next hurdle would be to explain to your Functional counterpart and your users why it was not working.
If this program was not developed by you, I can imagine how much you hate that person when you realized the root cause.

A silly mistake! On bright side, you are now Excel expert. Finally, DB would remove the duplicates and give you the result set. If you assume that all your fields would make up the unique value without including the Key fields, you are inviting trouble in the future. Adding the Key fields of the table would ensure that all the selected records are unique.
If you comment out the TEXT field from the 1st query, you would see more records are being dropped. This is due to the fact that, DB would only retain the unique records.
DB would compare the entire record with all records and would drop the rows. Data Integrity Performance. Explore all of his articles. Problem Once you have selected records from one table and need to get the relevant records from the dependent table, you generally use…. Not only that, the duplicated entries are deleted after we fetch the data from the Database, so you have to make sure you fetch the exact data you need!
Great article like others. First of all appreciate your works. As a BPC consultant currently, i also code my own ABAP works and trying to implement design patterns on my works by getting help from your articles thx again and i am also performance maniac also made many improvements on HANA systems and BPC by using some parallelization logic.
What FAE do is, it splits your select queries based on parameters and send select statements. For example we have matnr in internal table and we are selecting MARA. Disadvantage isit kills system resources :SAP suggests to use joins. While our tradional RDMS systems are changing, this approaches allso will change. Comment is a bit far from your main topic but releated with FAE also.
Thanks for the details about the parameters which can influence how FAE would work. I guess, I should have one more article on FAE with these details on how to further improve the performance.
Comments on this Post are now closed.Hi ,I have a requirement in which i want to read all the rows of an internal table for the set of values existing in another internal table BElow is a sample code. Is there any statement like select for all entries which can help me do so.
for all entries in sap abap for 3 tables
Hi HoracioThanx for ur reply. But i guess u didn't read my question nicely. I dont want to use a loop statement. I want a single statement. You cannot do this for itabs without using a loop. This is part of what Horacio was trying to tell you in 2. From: rinikalsi via sap-dev [mailto:sap-dev groups.
I've read your question nicely I would not recommend anything I haven't tested BTW, what's wrong with a loop? HTH Horacio. Para: Horacio Zapettini Asunto: RE:[sap-dev] reading all rows from an internal table for all rows in another internal table. Hope this helps. To put some more light here: this statement Provide is marked as obsolete. TK, I think you've missunderstood Rini's question.
She wants to extract records from an internal table using something like a select with for all entries She isn't selecting records from a ddic table. Well you'll have to write a lot, or you could try using form end form.
SAP ABAP Advanced Cookbook by Rehan Zaidi
Or you could try doing some redesignhaving the same internal structure for all the itabs. From: horacio zapettini via sap-dev [mailto:sap-dev groups. Rini: You can't get away from looping But the real issue is that you are looking for generic coding for multiple internal tables?
Then use field symbols to assign the table reference and components of those tables to loop on as part of the where clause. Crafted correctly, that will allow you to deal with the different structures involved with the same code.
How to Create Foreign Key Relationships
Come on, Rob Why couldn't he write an FM or form. See one statement Neal Wilhite via sap-dev [mailto:sap-dev Groups.
Para: Horacio Zapettini Asunto: Re: [sap-dev] reading all rows from an internal table for all rows in another internal table.
My thought was to have a unique structure with different fields filled in according to the source. But, it is unacceptable to wait for such a long time just because you don't want to use the tools you have. If I were your user I'd be shouting If I were your boss Solve the problem, and once the problem is solved you can do some research.
As you are coming back again and again this is no fun. My opinion 've read about create data and it's too new for me is that nested loops or similar algorithms would be easy to understand, easy to maintain, and easy to debug if something wrong comes in the future.
You're right.This blog is mainly intended for junior developers and consultants, who would like to discover the use of statement "For all entries" in addition to the "SELECT" command. This statement is often used since it is a simple and practical

 4. » Will jump in trash production lead to more workers' comp claims?
| May 14, 2020 | Workers' Compensation
Trash production is on the rise. A recent analysis by Public Works Departments through the state of Wisconsin found a 20% increase in April's trash production in Kenosha compared to the same time last year. Kenosha is not an outlier. Wauwatosa reports a 24.4% increase and Sheboygan reports a 19.5% increase.
Why is there so much more trash?
The increase in waste production demand for the Public Works Department is likely linked to the current coronavirus pandemic. More and more people are staying home. Instead of generating waste at the workplace, which often use private companies for waste disposal needs, people are generating trash at home.
Another reason for the increase: to help fill the extra time they have at home, people are taking on projects and cleaning out their homes. Both generate trash.
What does this mean for public works employees?
Although some cities throughout the state have shifted to automated garbage trucks, others have not. This means employees are lifting and tossing more and more bags of trash. This can lead to fatigue and serious injury such as herniated disks and torn rotator cuffs.
The same injury risk increase exists for municipalities that use private garbage/recycling companies. If an employee is injured while performing the duties of their job, workers' compensation benefits should be available.
What if a worker is injured?
Workers' compensation may be available for those injured while on-the-job.
Injured workers may need to navigate conversations with employers, insurance companies and doctors to get their claim approved. An attorney experienced in this area of the law can navigate these conversations and the application process on your behalf, better ensuring you get the compensation you are entitled.

Sun Java System Access Manager Policy Agent 2.2 Guide for BEA WebLogic Server 9.0/9.1
Enabling Port Check Functionality in J2EE Agents
In situations when Access Manager and the deployment container are installed on the same system but on different ports, certain browsers may not send the HOST header correctly to the agent in situations where there are redirects involved between Access Manager Authentication Service and the agent. In such situations, the agent, relying on the availability of the port number from the deployment container, might misread the port number that the user is trying to access.
When such a situation occurs, it can have a severe impact on the system since the agent now senses a resource access that in reality did not occur and consequently the subsequent redirects as well as any policy evaluations may fail thereby making the protected application inaccessible to the end user.
This situation can be controlled by enabling port check functionality on the agent. This is controlled by the following configuration property:
com.sun.identity.agents.config.port.check.enable
When this property is set to true, the agent verifies the correctness of the port number read from the request against its configuration. The configuration that provides the reference for this checking is set by the following property:
com.sun.identity.agents.config.port.check.setting
This property allows the agent to store a map of various ports and their corresponding protocols. When the agent is installed, this map is populated by the preferred port and protocol of the agent server as specified during the installation. However, if the same agent is protecting more than one HTTP listeners, you must add that information to the map accordingly.
When the agent discovers an invalid port in the request, it takes corrective action by sending some HTML data to break the redirection chain so that the browser can reset its HOST header on the subsequent request. This content is read from the file that resides in the locale directory of agent installation. The name of the file is controlled by the following property:
com.sun.identity.agents.config.port.check.file
This property can also be used to specify the complete path to the file that may be used to achieve this functionality. This file contains special HTML that uses a META-EQUIV REFRESH tag in order to allow the browser to continue automatically when the redirect chain is broken. Along with this HTML, this file must contain the string am.filter.request.url, which is dynamically replaced by the actual request URL by the agent.
You can modify the contents of this file or specify a different file to be used, if necessary, so long as it contains the am.filter.request.url string that the agent can substitute in order to construct the true request URL with the correct port. The contents of this file should be such that it should either allow the user to automatically be sent to this corrected location or let the user click on a link or a button to achieve the same result.

Bird-friendly meadowland management measurably benefits godwits according to researchers at the University of Groningen, based on four years of field work conducted in southwest Friesland. An egg laid in farmland with a higher water table, greater plant variety among the grass and a later mowing date has no less than a 17 times greater chance to lead to a mature godwit the following spring than an egg laid in highly productive, intensively farmed fields, in other words farmland managed in traditional fashion.
Researchers at the University of Groningen Department of Animal Ecology studied 850 godwit pairs between 2007 and 2010 on 8,741 ha of farmland in southwest Friesland. Twenty percent of this farmland was under bird-friendly management by private farmers and the nature preservation organizations It Fryske Gea and the National Forest Service (Staatsbosbeheer). Godwits were given coloured rings for the research, which meant they could be individually distinguished from a distance, and the survival rates of the chicks and mature birds could be monitored from year to year.
The 20% of the farmland under bird-friendly management was home to 60% of the breeding godwit population. The specially managed farmland was a source of new godwits during the study period, while the traditionally managed farmland was an ecological 'sink', where on balance more godwits died than successfully hatched.The major difference between the two types of meadowland was in the survival rate of eggs and chicks. Fifty-four percent of the eggs laid in farmland under bird-friendly management hatched successfully, as opposed to 32% of the eggs laid in traditionally managed areas.
A chick hatched in a bird-friendly meadow proved to have a ten times better chance to return as a breeding bird the following year. All in all, an egg laid in a bird-friendly meadow turned out to be 17 times more successful the following year. There was no difference in the survival rate of the mature birds in the two types of meadowland.
Apparently the godwits are aware of the better chances to be had. In general, the birds are very faithful to their nest sites. Most nests are within 300 metres of last year's nest site. However, if moves were made by godwits, this was more often from traditionally managed meadows to bird-friendly managed ones (23% of all breeding pairs), than vice versa (4% of all breeding pairs), despite the great difference in area.
On a national scale, the godwit population is still doing very poorly, with numbers dropping annually by over 5%. Stemming the decline is best achieved by investing in nest and chick survival. Once fully mature, godwits seem to have few problems surviving. Effective managementMeadow birds do have a future in the Netherlands but only in those areas with effective bird-friendly management: a high water table, so birds can dig for worms in the soft soil and the vegetation becomes more structured, greater plant variety with enough large insects for the chicks, sufficient cover, and only mown late in June, so eggs and chicks are not killed by the mowing machines. Only then will there be sufficient godwits produced to compensate for the birds that die.
- The research was conducted by the Department of Animal Ecology of the Centre for Ecological and Evolutionary Studies of the University of Groningen.

Molecular evolution and expression divergence of the Populus polygalacturonase supergene family shed light on the evolution of increasingly complex organs in plants
- Plant polygalacturonases (PGs) are involved in cell separation processes during many stages of plant development. Investigation into the diversification of this large gene family in land plants could shed light on the evolution of structural development.
- We conducted whole-genome annotation, molecular evolution and gene expression analyses of PG genes in five species of land plant: Populus, Arabidopsis, rice, Selaginella and Physcomitrella.
- We identified 75, 44, 16 and 11 PG genes from Populus, rice, Selaginella and Physcomitrella genomes, respectively, which were divided into three classes. We inferred rapid expansion of class I PG genes in Populus, Arabidopsis and rice, while copy numbers of classes II and III PG genes were relatively conserved in all five species. Populus, Arabidopsis and rice class I PG genes were under more relaxed selection constraints than class II PG genes, while this selective pressure divergence was not observed in Selaginella and Physcomitrella PG families. In addition, class I PG genes underwent marked expression divergence in Populus, rice and Selaginella.
- Our results suggest that PG gene expansion occurred after the divergence of the lycophytes and euphyllophytes, and this expansion was likely paralleled by the evolution of increasingly complex organs in land plants.

The difference between RO water and other differently treated water
ITEHIL's RO Water Purifier
The difference between RO water and other differently treated water
ITEHIL's RO water purifier is committed to solving the problem of outdoor drinking water safety. What is the difference between the RO water it produces and other treated water? Come and take a look with ITEHIL!
RO water: also called pure water, which is water filtered by reverse osmosis membrane. The pore size accuracy of the reverse osmosis membrane is 0.0001um, which can remove bacteria and viruses in the water, as well as more than 95% of ionic impurities.
Distilled water: Water obtained by utilizing the difference in volatility of each component in a liquid mixture to vaporize water and subsequently condense and separate the vapor portion. So there will be very little inorganic salt in it. Although the non-volatile components (salts) are removed, the volatile components (ammonia, carbon dioxide, organic matter) in the water will still enter the distilled water.
ddH2O: Distillation-Distillation H2O, water obtained by distillation twice, has fewer impurities than distilled water.
Deionized water: water from which all anions and cations have been removed. The ions in the water are mainly removed through RO membrane and mixed bed resin. Many people also call RO water deionized water, which is inaccurate.
Ultrapure water: Ultrapure water not only removes the conductive medium in the water almost completely, but also removes the undissociated colloidal substances, gases and organic matter in the water to a very low level.
Among them, ultrapure water is the water with the highest purity nowadays, followed by double-stage reverse osmosis water (dual-stage RO water), double-distilled water (ddH2O), pure water (RO water), and distilled water.

There are two sets of credentials you might need when renaming a scheduled task using Rename-ScheduledTask.ps1:
 - The -ConnectionCredential parameter specifies the credentials to use to connect to the schedule service on the computer where the task is stored (either the local computer or a remote computer). If you aren't a member of the Administrators group on the computer hosting the task, you can connect to the schedule service using administrator credentials.
 - The -TaskCredential parameter specifies the credentials for the task itself, if needed. Task credentials are needed only when the task's Run whether user is logged on or not option is selected and the Do not store password option is not selected. If credentials are required and you don't specify the
 -TaskCredential parameter, the script will prompt you for credentials.
Both the -ConnectionCredential and -TaskCredential parameters require a PSCredential object as their argument. A PSCredential object securely stores a username and password for use in security operations. However, there is an important caveat you need to know about: Rename-ScheduledTask.ps1 converts the secure passwords in PSCredential objects to plain text because the scripting object model doesn't support PSCredential objects.
You can easily create PSCredential objects by using the Get-Credential cmdlet. Run the command

in Cape Town is thought to be 90 per cent better than Johannesburg and does not detract from the average lifespan.
What impact does Johannesburg's poor quality air have on our health?
In several of South Africa's major cities, the air is often so polluted that it is killing them. Everybody is affected by this as we all have to breathe. It is estimated that the poor air quality in Johannesburg is robbing the lives of 54 people every day!
The data on what exactly is in the air has long been a secret between the regulators and those responsible for the emissions. However, this is not now the case. There is an established website (saaqis.environment.gov.za) where all information is now readily available for all to see. There is also an app that can be downloaded to a suitable smartphone for information "on-the-go".
Children are particularly susceptible as they breathe faster than adults and are often more active. After a period of heavy exertion, the particles lodge deeply in the lungs. Any pollutants which are carried by the particles soon break away and start to poison the new host.

Will the game be cancelled if it is raining?
For U10, U12, and U15, games will not be cancelled due to rain. The referees make the determination if the fields and conditions are unplayable, and that decision will not be made until the referees arrive at the fields and make the determination. Please come to the games prepared to play. For U6 and U8, the coaches together at the fields determine if the conditions are too bad to play.
What is the correct Age Division for my child?
Your child's division is determined by his/her age at the end of the calendar year. For example, if your child will be 9 years old (having a birthday in November) before the end of the current calendar year, your child will be playing in the U10 Division. If your child is not under 10 years old on December 31 of the calendar year, then your child does not play in the U10 division. He/she plays U12.

A polyomino (or simply omino) is a finite collection of orthogonally connected cells. The mathematical study of polyominoes was initiated by Solomon Golomb in 1953. Conway's early investigations of Life and other cellular automata involved tracking the histories of small polyominoes, this being a reasonable way to ascertain the typical behaviour of different cellular automata when the patterns had to be evolved by hand rather than by computer. Polyominoes have no special significance in Life, but their extensive study during the early years lead to a number of important discoveries and has influenced the terminology of Life.
A cross.
During the course of its evolution a polyomino could regain its original form, thereby constituting one phase of an oscillator, as seen in the (infinite) cross family. The only other known examples are the block (which has period 1), the blinker, the toad, the star and (in two different phases) the pentadecathlon. Were a recurring polyomino displaced, it would be participating in a spaceship, though the only known examples are the lightweight spaceship, the middleweight spaceship, and the heavyweight spaceship. Of course, its evolution could follow other trajectories, possibly very long lived.
Sizes of polyominoes
Polyominoes of with n cells for n = 1, 2, 3, 4,... are called haplominoes, dominoes, triominoes, tetrominoes, pentominoes, hexominoes, heptominoes, octominoes, and n-ominoes in general. The number of distinct polyominoes with n cells for n = 1, 2, 3,... is given by the sequence 1, 1, 2, 5, 12, 35, 108, 369, 1285,... (Sloane's A000105).
There is only one haplomino (also called monomino or dot) and by itself it dies after one generation. Several objects, such as the middleweight spaceship, produce dot sparks.
There is also only one domino and by itself it too dies after one generation. A number of objects, such as the heavyweight spaceship and the pentadecathlon, produce domino sparks.
Based upon that instant dying property of the domino, Squaredance is a low density dominos agar and phoenix.
There are exactly two distinct triominoes. The term is rarely used in Life, because the two objects in question are simply the blinker and the pre-block.
There are five distinct tetrominoes, each of which is shown below. The first is the block, the second is the T-tetromino, and the remaining three rapidly evolve into beehives. The fourth is commonly referred to as a tail and is often attached to small still lifes.
The five distinct tetrominoes. From left to right: O, T, I, J, Z.

There are 12 distinct pentominoes. John Conway assigned them all letters in the range O to Z, loosely based on their shapes, and they are all shown below in order.
 - The O-pentomino is a traffic light predecessor, though not one of the more common ones.
 - The P-pentomino is a common spark that dies in generation 4.
 - The Q-pentomino is a traffic light predecessor.
 - The R-pentomino is a methuselah and by far the most well-known pentomino.
 - The S-pentomino dies in generation 5.
 - The T-pentomino is a common parent of the T-tetromino.
 - The U-pentomino dies in generation 4.
 - The V-pentomino evolves into a loaf in generation 3.
 - The W-pentomino is a common loaf grandparent.
 - The X-pentomino is a traffic light predecessor.
 - The Y-pentomino dies in generation 3.
 - The Z-pentomino dies in generation 3.
There are 35 distinct hexominoes, the majority of which behave in uninteresting ways. The most interesting and well-known examples are century, stairstep hexomino, table, toad and Z-hexomino.
There are 108 distinct heptominoes. Those with names in common use are the B-heptomino, the bullet heptomino, the C-heptomino, the Herschel and the pi-heptomino.
There are 369 distinct octominoes. Despite the abundance of octominoes, the following fairly common octomino (or its two-generation successor), which stabilizes after 386 generations into two traffic lights and four beehives, is often referred to as simply the octomino:
The octomino and its two-generation successor.
Switch Engine
Charles Corderman discovered the switch engine by running an exhaustive computer search on all decominoes. The machine that discovered the decomino seed was unique, possessing an unusual architecture.
The name is a back-formation from 'domino', which explicitly refers to a pair of orthogonally connected live cells. According to the Life Lexicon, the pluralised name can be spelt two different ways: 'polyominos' and 'polyominoes' are both equally acceptable. The same applies to the systematic names of each of the polyomino sizes.

 The Magtalo prototype environment harnesses dialogue protocols to support flexible, intuitive interaction with data in complex, contentious domains and provides mechanisms for eliciting structured knowledge. Magtalo represents the first example of an implemented online system that uses a closely specified argument-based dialogue protocol combined with a rich language for representing monologic argument to provide a tool for intuitive user exploration of a disagreement space. This approach also enables the expansion of argument resources through knowledge elicitation, which is structured by the argument dialogue protocol. The continuing aim of our research is to use advances in argumentation theory to push the practice of argumentation technology in providing tools and interfaces that have wide appeal.

1. Introduction
Currently, composites are one of the most promising materials for use in new technologies [1,2]. The most widespread are laminates, fibrous (reinforcing component - the fibrous structure), and filled materials (the reinforcing component - particles). In turn, compared with laminated composites, cylindrical composites (fibers) have more compact structure, which is beneficial for device miniaturization [3,4]. Such composites are usually modeled by periodic sets of cylinders made of one material (filler) and placed in the second material (matrix). The calculation of effective parameters of the composite medium is based, as a rule, on the solution of the problem for the single cylinder (inclusion) in the surrounding external field and subsequent averaging procedure [5]. To be more precise, for the description of corresponding inclusions it is necessary to use the equations considering interactions of all possible fields: electromagnetic, elastic and thermal.
The surface and nonlocal effects start to play a significant role for the inclusions of size about one nanometer. Therefore, in general there is a need to solve the integro-differential equations. In our work, an average diameter of inclusions is assumed to be tens of nanometers and, thus, we can restrict ourselves by differential equations. Moreover, we analyze the case where the electrical properties of composites can be considered independently of the elastic ones. That is, it is sufficient to find the electric potential by means of the Laplace equation. In a classic work by Rayleigh [6], the electric potential was computed for a conducting composite consisting of a periodic array of inclusions (cylinders and spheres). More complex core-shell structures, which have appeared in recent years, allow one to improve the desired properties of composites. However, these structures complicate the determination of their properties even in the elementary cases [7-9].
Future prospects for the development of composites are associated with the finding of non-smooth fillings of untypical shapes. As already well known [9], the presence of peaks or edges of a filling leads to the appearance of singularities in the electric field that has a strong impact on the effective permittivity. The numerical calculation of such structures is not an easy task and requires skilled techniques for its solution (see, e.g. [9,10]). In this study, we investigate the possibility to control the dielectric constant by changing the distance between the boundaries of the different layers (shells). We consider the electric potential in the medium consisting of cylindrical inclusion in which one more cylinder is placed (see, Fig. 1). In other words, two dielectric cylinders are considered. If the cylinders have no common points, then the solution of an electrostatic problem can be found in [9,11]. Summing it up, this paper examines a cylinder completely immersed inside another one. A case of intersecting cylinders remains unexplored.
Note that due to the analogy between the stationary electric and thermal fields, the effective thermal capacity of a composite with inclusions in the form of eccentric cylinders can be determined by the same procedure.
2. The solution of the general problem
2.1. The problem statement
As a starting point, we consider an electric field in the system illustrated in Fig. 1. Inclusion consists of two eccentric circles of radii of r\ and r2 which centers are located at distance d from each other. The surfaces of
Fig. 1. The mutual arrangement of two dielectric cylinders
circles are Sij2. To describe electrostatic field, we employ a Cartesian coordinate system (x,y). By ei, e2 we denote dielectric permeability of circles and dielectric permeability of external space (matrix) by e0.
Similarly, we will use the subscripts 1,2 to identify quantities related to circles and subscript 0 for the matrix parameters. In the absence of any subscript, the expression is fulfilled in all environments. The intensity of the external electric field is supposed to be a constant vector of length E. In the solution of our problem it is necessary to find the potential u, which satisfies the two-dimensional Laplace equation:
Am = 0, (1)
and is continuous at the interfaces S1j2 together with the normal component of the electric displacement:
duo dui dui du2
uo Si = ui s1, ei—— = e2—— , ui S2 = U2 S2, ei —— = . (2)
on on on on
S1 Si S 2 S2
Moreover, at the distance far from the inclusion, the potential u tends to the potential of the external field:
u0 ^ —E0(x cos y + y sin y). (3)
Here, n is normal to the surfaces Sij2, E0 is the electric stress, and y is an angle between the external field and the x-axis. Because of the lack of symmetry, the solution of Eqs. (1)-(3) depends on the angle y.
If we introduce the potential U that tends to U0 = x + iy at large distances from the inclusion, then the desired potential u can be expressed in terms of U as:
u = —E0(ReU cos y + ImU sin y).
(4)
Further, it is reasonable to switch to a bipolar coordinate system (a, ¡3) [12] associated with the Cartesian by the relations:
x + iy = c tanh If we define the parameters ai, a2 and c from:
a + i3
(5)
cosh a,-
— r2 + ( —l)j d2 2jd :
c = r1 sinh a1,
(6)
then the circles' boundaries are the coordinate lines a = aij2. The solution of the stated problem will be sought in the form:

Uo = x + iy + ao„e

Ui = £ [alnen(a-2ai) + blne U2 = £ b2nein^

The Fourier coefficients ajn and bjn in Eq. (7) are uniquely determined by taking into account boundary conditions. In particular
aon = 2c(-1)n, An = £iOn±1, Sn = £i±£l e2n(a2-ai). (8)
An + 1 £o On — 1 £2 — £l
The coefficients ain and blj2n have a similar form. For simplicity we do not write down explicit equations for these coefficients.
2.2. The Maxwell-Garnett theory
Let us now discuss the influence of the cylinder eccentricity on the effective characteristics of the medium. First, we consider the main principles of the Maxwell-Garnett theory for the set of identical inclusions randomly arranged in the matrix. Each of these inclusions consists of n dielectric layers with

3. The type of stories you tell them will affect the kind of character they develop. Stories should be long.
4. Always answer their questions honestly. If you don't know say so. Admit it and then work with them to find out. Once they find out the true answers from teacher they will lose all respect for you. When this happens you wont be able to control them at all.
SOOTRA TWO
1. Let them sleep as much as they want. Never stop them from sleeping as it is essential for them. Upto 10 hrs a day is fine. Its better that the child takes this sleep in two parts.
2. 1 – 4 yrs minimum sleep of 16 hrs
3. 4 – 8 yrs min 12 to 14 hrs
4. 8 – 14 yrs min 8 to 9 hrs
5. Kapha is heavy or guru and hence if the child needs to sleep more in order to keep the blood pressure under control. While sleeping BP is lower. Child is under Kapha effect and hence needs to sleep more to maintain BP.
6. Children will become irritable and undisciplined if they are not allowed to complete their sleep quota as their Kapha is out of control.
7. Studying is only possible in effect of Pitta. When Kapha is bad no one can study.
8. Area above the heart is Kapha area. Children will frequently catch ailments of this region only. The best way to take care of this is oil massage. This should be a must. Children should not do any exercises. They should only play.
9. Those under Kapha should not exercise, asana or pranayam.
SOOTRA THREE
1. Oil massage should be of entire body. But head area is most important. Ears should also be massaged regularly as they are seat of Kapha. Bathing should be done after massage.
2. Massage till the child starts sweating in the arm pits or forehead.
3. Things that reduce Kapha should be used for bathing. Eg. Ubtan, Multani mitti, Chana atta, chandan powder, mota aataa, masoor daal ataa, moong daal attaaa. Finally means that no soap should be used. It increases Kapha very badly.
4. Oil can be put into ears. Its also helpful in controlling Kapha.
5. Eyes are also seat of Kapha. Ghee can be put on eyes. Kaajal is very useful in controlling Kapha (Sau veer anjan).
SOOTRA FOUR
1. Children must be given milk, makhan, ghee, oil, gud, dahee, mattha etc.
2. Maida is absolutely not allowed since it disturbs Kapha.
3. Makkhan is better than ghee for children.
4. Ghee things should be given in afternoon as pitta is increasing.
5. Out of control kapha can make one a criminal and murderer. If under control it promotes love and harmony.
6. American children are considered the worst – shootouts in schools etc are proof. 10% of America's population are children and out of this 10% or 30 lac
children are in prisons. This is common for most western countries. The main reason is out of control Kapha.
7. Of the total crime happening in these countries upto 65% are being committed by children. Direct result of out of control Kapha. It leads to violence directly.
8. Simplest way to keep children safe from all types of negative influences is to let them sleep as much as they want to.
9. Morning time for schools is very bad. Its not good for children to wake up early in the morning. As morning is Kapha time and hence they sleep the deepest sleep. Best time for school to start is around noon.
SOOTRA FIVE – PITTA PRAKRITI
1. Not too much sleep is needed. Ideally between 6 to 8 hrs. This decides the routine to a large extent.
2. Mharishi Waaghbattha says one should sleep 2 hrs after sunset. So if you sleep at 8 then you will be up at 4am.
3. 12 types of daatoon can be used only.
4. DAATOON
5. There are 3 basic season and 3 sub seasons. In summers neem daatoon, babool,
6. Winters, amrood is best, jaamoon is next
7. Rains – mango, Arjun
8. Dant manjan1 – daaru haldi, salt, oil
9. Dant manjan 2 – burn dried gobar, add haldi and sendha namak to it.
10. Dant manjan 3 – triphala choorna, sendha namak. This is the only one that can be used in all seasons.
11. Tooth paste is not good for you. They disturb Pitta. This will cause many problems. Teeth will decay very quickly due to paste use. When sweet things are eaten early in the morning they disturb the system. Our culture has a system to eating neem and turmeric balls.
12. Commercial toothpastes have been using powdered animal bones for decades e.g. Colgate - pig bones, pepsodant – cow bones, close up – goat. This has been proven in lab tests and it seems only recently that some of these companies have stopped using bones.
 - 1. VYAYAAM first and then massage. Exercise only till you start sweating.
 - 2. India is a vaat pradhaan land hence running is not good. i.e. Vaata is dominant in India and running or any fast movement aggravates it hence should be avoided.
 - 3. Best exercise is soorya namaskar and asanas. Dand baithak etc is good. For women the best exercise is forward bending.
 - 4. After exercise oil massage.
SOOTRA SIX – VAAT PRAKRITI
Vaata naturally increases after 60 yrs of age.
1. Main remedy is oil massage for old people. A little bit of exercise is ok.
2. Too much movement is not good for them.
Human urine – can be used as medicine. Condition is you must be 100% vegetarian. Gau mootra is much better compared to human urine. Only the 1st urine in the morning is to be used. While urinating leave the initial and last parts and drink only from the middle part of urine. Helps in around 100 illnesses. Mainly vaata and kapha problems.
Laughing is good if it happens naturally. One should never try to force it or stop it. It is one of the 14 'veg' of natural forces in the body. This is true for all the other 'veg'.
Sneezing should not be stopped – upto 40 types of ailments will come if stopped and upto 14 types if induced forcefully.
Thirst should also never be stopped. Drinking water quickly causes Hernia and Appendicitis. If you are above 60 and it can cause Prostrate and Hydrocele. Holding back thirst causes 58 types of ailments. Drinking water without thirst will also cause problems.
Hunger, when forcefully stopped, causes 103 types of ailments. Starts with acidity and ends with intestinal cancer!
Fasting is a Kriya to cleanse the body and mind. One needs to follow certain rules for fasting. When you start feeling that something extra is happening in the body then one can fast. Like after eating too much one can fast the next day.

a) Upto one day fast after 6 days of eating normally.
b) While fasting one should keep drinking warm water at regular intervals. The extra acid in the stomach will be diluted by water and excreted via urine else it will burn up/ damage the intestines.
c) Water can be of clove, moong, ghee, choona while fasting.
d) Vegetarians should not fast for long periods. While non-vegetarians should always fast for long periods. Non veg food creates certain changes in the digestive system (reduces acid secretion in stomach) and hence it is advisable to fast for long periods. All carnivorous animals actually fast for many days after a full meal.
e) Best way to fast if one has to fast is alternate day fasting and eating. The body gets used to it over a period of time. Varshitam in Jains is highly respected.
f) Fasting is not good for those who do heavy physical labour.
Yawning should also not be stopped. Stopping it is a very bad habit that we have gotten into. The body's need is more important.
a) Never yawn when sitting near those who are more tapasvi or gyani.
Urine should never be stopped.
a) Pressure of all types in the body increases. Stopped urine is one of the most painful experiences in life.
b) If urination is too frequent then you need to check with specialist.
Stool is also similar. Upto twice a day is normal. Three is a bit unusual. More than that calls for expert intervention.

Green licens
Green salmon licens aim to improve the industry's environmental work and are given to companies that work to solve environmental challenges. This means that the company has some self-imposed criteria that have been accepted as innovative. The goal here is to reduce louse pressures and other environmental challenges. In 2014, Salaks AS was awarded a green license, where the most important measure here was to launch large-smolt in the sea.
Traditionally, smolt has been put out in the sea when they are 70-100 grams, where the production time in the sea is 15-18 months. By building a new recycling plant that produces 250 grams of smolt, we can reduce the production time in the sea by 6-8 months. We will, with the help of new technology, move the first phase of salmon's life into the sea on land. By doing this, we reduce production time on sea. In addition, it is possible to reduced mortality in the sea phase, a 250 grams smolt is more robust and equipped for seawater phase than a 70-100 grams smolt. The bilogic pressure on the sea is reduced. The time when the fish can be exposed to louse is reduced, and we ca avoid some technical operations in the sea, which involves moving fish from smolt bag to bigfish bag. Overall, a risk reduction, based on a principle that every day and operation involves risk. The new recycling plant is being built and completed in the summer of 2017 at Salangsverket, in Salangen. The plant has a price tag of 300 million NOK, and is going to produce six million 250 grams smolt.

Abstract : Results are presented from a search for a fourth generation of quarks produced singly or in pairs in a data set corresponding to an integrated luminosity of 5 inverse femtobarns recorded by the CMS experiment at the LHC in 2011. A novel strategy has been developed for a combined search for quarks of the upand down-type in decay channels with at least one isolated muon or electron. Limits on the mass of the fourth-generation quarks and the relevant CKM matrix elements are derived in the context of a simple extension of the standard model with a sequential fourth generation of fermions. The existence of mass-degenerate fourth-generation quarks with masses below 685 GeV is excluded at 95% confidence level for minimal off-diagonal mixing between the thirdand the fourth-generation quarks. With a mass difference of 25 GeV between the quark masses, the obtained limit on the masses of the fourth-generation quarks shifts by about +/- 20 GeV. This result significantly reduces the allowed parameter space for a fourth generation of fermions.

Aberdeen Proving Ground (APG) is a United States Army facility located near Aberdeen, Maryland, (in Harford County). Part of the facility is a census-designated place (CDP), which had a population of 3,116 at the 2000 census.
APG is the U.S. Army's oldest active proving ground, established on October 20, 1917, six months after the U.S. entered World War I. Its location allowed design and testing of ordnance materiel to take place near contemporary industrial and shipping centers. The proving ground was created as a successor to the Sandy Hook Proving Ground, which was too small for some of the larger weapons being tested. At the peak of World War II, APG had billeting space for 2,348 officers and 24,189 enlisted personnel.
Other parts of APG not attached to the main installation include the Churchville Test Area in Harford County, and the Carroll Island and Graces Quarters in Baltimore County, Maryland. The Churchville Test Area is a test track with hills that provide steep natural grades and tight turns to stress engines, drivetrains, and suspensions for army vehicles, including M1 Abrams tanks, Bradley Fighting Vehicles, and Humvees.
Edgewood Chemical Activity is a chemical-weapons depot located at APG. Elimination of the chemicals held here was put on an accelerated schedule after the September 11, 2001, attacks, and all chemical weapons were destroyed by February 2006.
APG is located at and occupies a land area of 72,962 acres (114.0 sq mi; 295.3 km2). Its northernmost point is near the mouth of the Susquehanna River, where the river enters the Chesapeake Bay, while on the south, it is bordered by the Gunpowder River. The installation lies on two peninsulas separated by the Bush River. The northeastern is known as the Aberdeen Area and the southwestern is called the Edgewood Area (formerly the Edgewood Arsenal).
According to the U.S. Census Bureau, the CDP has a total area of 12.0 square miles (31.1 km2), of that, 11.4 square miles (29.5 km2) of it is land and 0.6 square miles (1.6 km2) of it (5.09%) is water.
As of the census of 2000, there were 3,116 people, 805 households, and 763 families residing in the CDP. The population density was 274.1 people per square mile (105.8/km²). There were 902 housing units at an average density of 79.3/sq mi (30.6/km²). The racial makeup of the CDP was 50.5% White, 34.6% African American, 0.6% Native American, 3.1% Asian, 1.3% Pacific Islander, 5.7% from other races, and 4.2% from two or more races; 11.2% of the population were Hispanic or Latino of any race.
There were 805 households out of which 78.0% have children under the age of 18 living with them, 84.1% were married couples living together, 8.0% had a female householder with no husband present, and 5.2% were non-families; 4.3% of all households were made up of individuals and none had someone living alone who was 65 years of age or older. The average household size was 3.52 and the average family size was 3.63.
In the CDP the population was spread out with 40.1% under the age of 18, 10.3% from 18 to 24, 44.9% from 25 to 44, 4.4% from 45 to 64, and 0.2% who were 65 years of age or older. The median age was 25 years. For every 100 females there were 113.9 males. For every 100 females age 18 and over, there were 117.6 males.
The median income for a household in the CDP was $38,875, and the median income for a family was $40,306. Males had a median income of $26,943 versus $26,194 for females. The per capita income for the CDP was $12,808. About 4.2% of families and 5.6% of the population were below the poverty line, including 6.4% of those under age 18 and none of those age 65 or over.
Under the Base Realignment and Closure (BRAC) program, as announced in 2005, the APG is projected to lose the Ordnance School and associated R&D facilities with 3862 military and 290 civilian jobs moving to Fort Lee, Virginia. APG will gain 451 military and 5,661 civilian jobs from Fort Monmouth, New Jersey. There is a net loss of 3,411 military jobs under BRAC and a net gain of 5,371 civilian jobs.
In 2005, APG executed an Enhanced use lease (EUL) partnership with Opus East, L.L.C. (a subsidiary of Opus Corporation), a commercial real-estate development company. The EUL allows APG to ground lease "temporarily underutilized" land of the installation to a selected real estate developer. APG uses the proceeds from the ground lease for facility improvements and maintenance on the installation (i.e., new buildings, infrastructure improvements, deferred maintenance, road upgrades on post, etc.). In June 2009, Opus East assigned its EUL development rights to St. John Properties, Inc., a Baltimore-based commercial real estate development firm.
Under the EUL, St. John Properties has entered into a long-term ground lease of federally owned property for the development of commercial office space and research-and-development (R&D) space. The EUL development will provide new, high-quality buildings and facilities for the military/civilian tenants and their supporting government contractors who are relocating to APG because of the 2005 round of the BRAC process. The development of the EUL, known as The GATE Office and Technology Park or "The GATE" project, comprises 416 acres (1.68 km2), 11 land bays, and up to 3,000,000 square feet (300,000 m2) of development potential both inside and outside the secure perimeter of APG. St. John Properties is building new speculative office and R&D buildings for lease to both defense contractors and military/federal agencies.
In addition to office and R&D buildings, St. John Properties is developing an office and retail component just outside APG's security gate. The GATE is being developed to meet anti-terrorism and force-protection standards, and will include sustainable-design elements to achieve LEED Silver Certification. The GATE is strategically located to allow private military contractors (PMCs) doing work for various military commands on APG to be closer to their client. The first building at The GATE was delivered in 2008 to CACI, an information-technology security PMC. In October 2010, L-3 Communications took occupancy of a 75,000 square feet (7,000 m2) building at The GATE, as did Raytheon Company, another 75,000 square feet (7,000 m2) building. In 2010, St. John Properties delivered three additional speculative buildings for lease. Complete development of The GATE project is expected to span five to 10 years.

Abstract
An Expectation Maximization algorithm for identification of DNA binding sites is presented. The approach predicts the location of binding regions while allowing variable length spacers within the sites. In addition to predicting the most likely spacer length for a set of DNA fragments, the method identifies individual sites that differ in spacer size. No alignment of DNA sequences is necessary. The method is illustrated by application to 231 Escherichia coli DNA fragments known to contain promoters with variable spacings between their consensus regions. Maximum-likelihood tests of the differences between the spacing classes indicate that the consensus regions of the spacing classes are not distinct. Further tests suggest that several positions within the spacing region may contribute to promoter specificity.

Homer's "Odyssey" may have historical fact
Homer's possible reference to a solar eclipse helped scholars date Odysseus' return from the Trojan War.
It was on April 16, 1178 B.C. that the great warrior struck with arrows, swords and spears, killing those who sought to replace him, a pair of researchers say in Monday's online edition of Proceedings of the National Academy of Science.
Experts have long debated whether the books of Homer reflect the actual history of the Trojan War and its aftermath.
Marcelo O. Magnasco of Rockefeller University in New York and Constantino Baikouzis of the Astronomical Observatory in La Plata, Argentina, acknowledge they had to make some assumptions to determine the date Odysseus returned to his kingdom of Ithaca.
But interpreting clues in Homer's "Odyssey" as references to the positions of stars and a total eclipse of the sun allowed them to determine when a particular set of conditions would have occurred.
"What we'd like to achieve is to get the reader to pick up the "Odyssey," and read it again, and ponder," said Magnasco. "And to realize that our understanding of these texts is quite imperfect, and even when entire libraries have been written about Homeric studies, there is still room for further investigation."
Their study potentially adds support to the accuracy of Homer's writing.
"Under the assumption that our work turns out to be correct, it adds to the evidence that he knew what he was talking about," Magnasco said. "It still does not prove the historicity of the return of Odysseus," he said. "It only proves that Homer knew about certain astronomical phenomena that happened much before his time."
Homer reports that on the day of the slaughter the sun is blotted from the sky, possibly a reference to an eclipse. In addition, he mentions more than once that it is the time of a new moon, which is necessary for a total eclipse, the researchers say.
Other clues include:
- Six days before the slaughter, Venus is visible and high in the sky.
- Twenty-nine days before, two constellations -- the Pleiades and Bootes -- are simultaneously visible at sunset.
- And 33 days before, Mercury is high at dawn and near the western end of its trajectory. This is the researchers' interpretation, anyway. Homer wrote that Hermes, the Greek name for Mercury, traveled far west to deliver a message.
"Of course we believe it's amply justified, otherwise we would not commit it to print. However we do recognize there's less ammunition to defend this interpretation than the others," Magnasco said.
"Even though the other astronomical references are much clearer, our interpretation of them as allusions to astronomical phenomena is an assumption," he added in an interview via e-mail.
For example, Magnasco said, Homer writes that as Odysseus spread his sails out of Ogygia, "sleep did not weigh on his eyelids as he watched the Pleiades, and late-setting Bootes, and the Bear."
"We assume he means that as Odysseus set sail shortly after sunset, at nautical twilight the Pleiades and Bootes were simultaneously visible, and that Bootes would be the later-setting of the two," Magnasco explained.
"It is a good assumption because every member of his audience would know what was being discussed, as the Pleiades and Bootes were important to them to know the passage of the seasons and would be very familiar with which times of the year they were visible. Remember the only calendar they had was the sky."
Since the occurrence of an eclipse and the various star positions repeat over different periods of time, Magnasco and Baikouzis set out to calculate when they would all occur in the order mentioned in the "Odyssey."

Homei Miyashita from the Miyashita Lab at Meiji University in Japan has created the Norimaki Synthesizer, a lickable "taste gadget" or electronic flavor saver. The device is a part of the broader study of human-centered computing or human-computer interaction (HCI).
The novel taste display uses ion electrophoresis. It has five gels that contain electrolytes that supply controlled amounts of five basic tastes: magnesium chloride is bitter, citric acid is acidic, glutamic sodium is umami gel, sodium chloride is salty, and glycine is sweet.
The device applies different tastes to the user's tongue that roughly correlate to colored lights, sort of in a way that Jolly Rancher colors represent "natural flavors."
When applied to the tongue without voltage, the user tastes all five flavors. When an electric potential is applied, the cations in the gel move to the cathode side and away from the tongue, so that the flavor is suppressed.
The taste display can reproduce arbitrary tastes by individually suppressing the sensation of each of the five tastes. The synthesizer uses electric current for electrophoresis rather than electrically stimulating the tongue. The user also doesn't have to swallow to deliver the flavor.
The project builds off of previous work trying to augment taste using devices. For example, chopsticks and straws that alter flavor by conducting electricity, changing soup with electric spoons, applying electrodes to the face, and even inserting a device into the mouth and generating power using chewing force.
Electronically altering your palette may sound weird, but how many of you still go heavy on the salt? You could make your food taste saltier without shocking the ticker, or consider margaritas with a virtually salted rim.
If anything, the device could open up an entirely new multimedia experience, such as in virtual reality environments or as a part of 4D theme-park attractions.

Cajun and folk music have a lot in common and are often compared to each other. Mostly because they are both ever-evolving histories of a certain people.
South Louisiana has multiple dialects that come from the French language. There are three main dialects: the French that came from the French descendants who first settled Louisiana in 1699, the Creole which came from intermixing of African settlers and the Acadians that wandered south to New Orleans, and Cajun French that came from the Acadians who settled in the grasslands and bayous. The languages reflect the areas where the groups had settled and had frequent interactions. After the Louisiana Purchase, French Louisiana was forced to adapt the language and culture of the United States and their languages were not passed down to their children.
