Abstract: Abstract. This paper focuses on the turbulence structure in a non-uniform, gradually varied, sub-critical open channel flow (OCF) on a rough bed. The flow field is analysed under accelerating, near-uniform and decelerating conditions. Information for the flow and turbulence parameters was obtained at multiple sections and planes using two different techniques: twocomponent laser Doppler velocimetry (LDV) and particle image velocimetry (PIV). Different outer region velocity scaling methods were explored for evaluation of the local friction velocity. Analysis of the mean velocity profiles showed that the overlap layer exists for all flow cases. The outer layer of the decelerated velocity profile was strongly affected by the pressure gradient, where a large wake was noted. Due to the prevailing nature of the experimental setup it was found that the time-averaged flow quantities do not attained equilibrium conditions and the flow is spatially heterogeneous. The roughness generally increases the friction velocity and its effect was stronger than the effect of the pressure gradient. It was found that for the decelerated flow section over a rough bed, the mean flow and turbulence intensities were affected throughout the flow depth. The flow features presented in this study can be used to develop a model for simulating flow over a block ramp. The effect of the non-uniformity and roughness on turbulence intensities and Reynolds shear stresses was further investigated.

text: The temporal dynamics of water repellency in soils strongly influence water flow. We investigated the variability of soil water content in a slight slope on a sandy fairway exhibiting water-repellent behavior. A time domain reflectometry (TDR) array of 60 probes measured water contents at 3-h intervals in a transect along the slope at four depths across a length of 4.5 m. A recently developed animation program was used to visualize the complex way water infiltrates into the soil. Measurements commenced 14 May 2003. Starting on 29 Mar. 2004, the same equipment was used to determine the effects of soil surfactant applications on preventing the development of water repellency and reduction of heterogeneous wetting of the soil along the slope. Additionally, soil water contents in the upper 5 cm of both the untreated and surfactant-treated areas were measured with a hand-held TDR device on five occasions between 10 May 2005 and 22 Mar. 2006. On the same dates, soil cores were taken to determine the presence of soil water repellency. The temporal dynamics of water repellency along the slope strongly influenced water flow and the appearance of preferential flow paths. Variability of the soil water content in the untreated slope following rain events is illustrated with two "movies" constructed using the actual measurements. Surfactant applications prevented the development of actual water repellency, which resulted in a more homogeneous wetting even during the summer period of 2005. The soil water contents in the surfactant-treated area are shown in a third "movie." The ability to animate the data allows better representation of the actual dynamics of water flow in the sloped test area.

In almost all countries, the responsibility for regulating drugs belongs to government. However, depending on national circumstances, the government may delegate certain regulatory activities to the private sector, such as consumer groups, expert or interested groups, professional associations or industry associations.
Within government, the division of drug regulation responsibilities will vary from country to country, depending on national conditions. Some examples are given in Box 2.
Box 2. Assignment of Drug Regulation Responsibilities in Three Countries Zimbabwe
The Medicines Control Authority of Zimbabwe is an independent body with the capacity to sue and be sued. The Authority is accountable to the Minister of Health and Child Welfare but managed by an executive committee that has legal powers and which is independent in its decision-making. Drug regulatory decision-making is centralized and is the responsibility of the Authority. The Authority has the power to collect and use fees, or to raise other money and assets. It can also employ its own staff.
In Tunisia, the authority responsible for drug regulatory affairs (Direction de la Pharmacie et du Medicament (DPM)) is organized as a department of the Ministry of Health, under the supervision of the Director-General of Health. Other semi-autonomous units supervised by the Director-General of Health, and that are involved in drug regulatory affairs, include the Laboratoire National de Controle de Médicament, the Institute Pasteur, the Direction de l'Inspection Pharmaceutique, the Laboratoire Nationale de Controle and the National Pharmacovigilance Centre. DPM supervises the administrative work and coordinates the activities of all the units involved in drug regulation.
In India, responsibility for drug regulation is divided between the federal government and the country's 31 states. Each state has its own drug control organization (responsible for quality control of drugs) and a licensing system covering the manufacture, sale and distribution of drugs. Each state employs drug inspectors as the first line of enforcement and the state authorities issue WHO-type certificates. Federal authorities are responsible for developing standards for drugs, quality control of imported drugs, coordination of state activities, provision of expert advice to ensure consistency in enforcement, and control of manufacture of vaccines, sera and blood products. Four port offices under the federal authority regulate imports.
The examples in Box 2 show that no standard formula exists for organizing drug regulation. Rather, when planning drug regulation, countries should consider all options open to them, and choose the most appropriate structure. Such a structure should provide: independence in decision-making, financial and administrative autonomy (including in appointment of staff) and, accountability to the highest government body responsible for health and the general public. In countries where the government is also the owner of pharmaceutical industries and import-export companies, drug regulation responsibilities must be separated from management of those companies, if conflict of interest is to be avoided.
If several agencies or divisions or departments are involved in drug regulation, care should also be taken to ensure appropriate distribution of responsibilities, duties, functions and powers between the different bodies. This should be done in accordance with the drug legislation or written terms of reference. There should also be written terms of reference that describe the linkages between the various bodies. Also, as far as possible, related activities should be grouped together since they will require a high degree of coordination and will need to be carried out by personnel of similar training and experience. Tasks should be divided so that no supervisor carries an excessively heavy load. Functions that need to be centralized should be carried out at central level and a mandatory reporting system between the different levels should be operated. A planning, monitoring, evaluation and reporting system should be built into the regulatory hierarchy so that implementation of drug regulation can be assessed, shortcomings and the reasons for them identified, and timely decisions to correct them taken.
Agencies, such as consumer unions, professional associations and industry associations, that are involved in drug regulation but who do not form part of government drug regulation, should also be required to operate in accordance with written terms of reference or an established code of practice, in line with national drug legislation. Their role, responsibilities, and powers with respect to drug regulation must be clearly defined.

How to Saw on a Jigsaw
Jigsaw is one of the most common hand-held electric tools. They can process a wide variety of materials: wood, plastic, ceramics, metal, etc. However, the main material that most jigsaw masters work with is plywood.
Using a narrow file, this tool allows you to carry out not only a direct cut, but also perform intricate patterns. And in this article we will consider some tips from specialists working with a jigsaw.
An example of drawings for sawing with a jigsaw.
Features of working with a jigsaw
An electric jigsaw for sawing plywood in appearance is a very simple tool and almost every beginner will be able to make an even cut with it. However, if we talk about beautiful curly patterns, then it is necessary not only to have certain skills, but also to choose the right file.
The main nuances
Carrying out electric sawing from plywood with your own hands, you should know the following:
- The main condition for obtaining an even cut is the correct choice of the file for the tool. In order for the cut to be on the front side without burrs, it is necessary to use a thin file, the teeth of which are directed downward.
- The workpiece needs to be firmly fixed, otherwise a smooth cut will not work
- A few words about the nail files. For jigsaws a large number of saws are produced, which differ from each other, both in thickness and design features.Depending on this, they distinguish:
- Saw or side scam. The teeth are bent to the right and left in turn, as with hand saws. In this way, files with relatively large teeth are made. They are used for quick direct cutting. Propyl is obtained with rough edges, so it should be treated with sandpaper.
- Canvas with undercut. In this case, the teeth do not have a divorce at all. Such files allow you to make very thin and clean cuts. Naturally, the speed of this drops. If such a file has a small divorce, then the work will go slightly faster. However, in this case, the main emphasis is not on speed, but on the quality of the cut.
- Wave-like divorce. In order for very small and narrow files to be able to make wider cuts, the cutting edge of the blade is made wavy. For the most part, such files are used when working with metal, but are often used when working with plywood to produce narrow and clean cuts in a fairly short time.
Types of files.
Sawing patterns with a jigsaw
Like a regular hand jigsaw, this power tool allows you to cut various curly patterns on the material. Most often, sketches are taken by masters from magazines. (see also the article Plywood do-it-yourself rocking chair: drawings to help)
How to Saw on a Jigsaw
Advice!You can use patterns from magazines for embroidery, knitting or paper cutting.
In order to transfer the drawing to plywood, do the following:
- We translate the pattern onto thick paper.
- Using a sharp clerical knife or scalpel, we cut out the stencil.
- We apply the stencil to the surface of the material, circling it with a simple pencil.
- Now you can start cutting out the pattern.
Drawing a picture on a material through a stencil.
In contrast to the implementation of direct cut, sawing from plywood with a jigsaw has its own characteristics.
This instruction will help you understand all the intricacies of the work:
- For cutting along a curve, use a file with a narrow blade.
- To cut a circle in plywood, you need to use a special nozzle. A circular cutter. The cutter is fixed in the center of the circle, after which you can begin to work.
- If you need to choose grooves in a wooden blank, then a rasp can be used instead of a saw. It is also used to strip uneven cuts.
- In order to achieve perfectly accurate and even cuts, use the parallel stop. It must be attached to the jigsaw with screws.On the "ski" can be installed a special guide line, thanks to which the cut is parallel to the straight edge. Before you begin, you must make sure that the ruler is firmly fixed and aligned with the canvas. Otherwise, the movement of the file will be incorrect, and it may break, or "burn" the processed material.
Use of a parallel emphasis.
- If you need to make a straight long cut, you can use the auxiliary guide. In this case, the jigsaw will move along the firmly fixed strap.
- With the help of this tool it is possible to carry out cuts at an angle of up to 45 degrees. The angle of inclination is set on a scale.
The implementation of an inclined cut.
- Sawing a hole. Very often, cutting ornaments, the master needs to make a hole in the plywood.There are two options for this:
- The first option is the simplest. You need to drill a hole with a drill, after which you introduce a file into it and continue to cut out the necessary pattern.
- The second option involves the use of mortise or plunger sawing technology. Do not drill the start hole. To do this, put the tool on the front edge of the "ski", without touching the workpiece with the canvas.
Next, turn on the engine and gradually lower the fork, smoothly introducing the saw into the material until the saw takes a vertical position, and the "ski" does not come into contact with the workpiece.
Advice!Cutting should always start at the waste of the material.The saw should not enter the plywood too close to the cutting line so as not to spoil the material.
- In the event that you need to cut a board of large thickness and the file length is not enough for this. You need to use a file with a pointed end. First, we saw it with a workpiece on one side, then we turn it and saw it on the other.
- To cut a curly part, you can fix the tool from the bottom of the desktop. In the case of a uniform and smooth feeding of the workpiece, you can get a cut with clean, even edges.
In the photo. A tool attached to the bottom of the desktop.
From this article, you learned how to saw plywood with a jigsaw. Here we examined the basic principles of working with this tool, which will help you in the implementation of various construction and design solutions.
Having understood the features of the jigsaw, you will soon realize how simple and convenient the appliance is. And although its price is higher than a conventional jigsaw, you will not regret that you purchased such a tool. (see also the article Cutting with a jigsaw from plywood. Success drawings)

Do You Know Why Surgeons Wear Blue And Green Scrubs During Surgeries?
As the problem is mainly with the green coloured optical illusion, it is logical to use green scrubs while surgery. This helps to blend the annoying green colour illusion of organs of the patient in the green scrubs. The combination of white surroundings, white apparel, and bright operating room lights, however, was believed to cause eye strain for surgeons and staff. As a result, operating-room attire was changing to various shades of green by the 1960's. Among other benefits, shades of surgical green as well as blue were found to reduce eye fatigue, provide a high-contrast working environment and make bloodstains less obvious. These shades in replacement of white could help physicians see better for two reasons.
This is the reason why doctors wear only green or blue clothes during the operation. There is a big reason for wearing green and blue clothes in the operation theater. Along with this, there is some scientific Pharmaceutical uniform hire service reason behind this, due to which, during the operation or surgery of a patient, doctors and nurses wear only green or blue clothes. During the operation, doctors have to watch blood for a long time.
If they stare at the white coat again at this time, they will have illusion. But did everyone blindly agree to this green colour change or there was any scientific reason behind it? Did you get the answer of why doctors wear green clothes during surgery? Alright, the next section will answer your query in a scientific way. As the doctors vision continuously focused on the red colored patient's organ, where the red color can cause green colored optical illusion on the white colored surface and certainly can be annoying.
Today we will give you a complete and detailed answer to this question. Seeing green or blue colour from time to time actually makes a doctor's eyes more sensitive to red colour. Green also happens to be the saviour as it is a complete opposite to red, thereby reducing the illusions. Contrasting colours like blue or green help to differentiate between the red and pink organs and tissues of the human body which is a big requirement in the surgery. This in turn has an advantage of better concentration on the patient and his/her anatomy. Thus, looking at blue or green during the surgery helps refreshing the surgeon's vision of red things.
Since then, most doctors started wearing green clothes, although some doctors also wear blue clothes. There are two major reasons why green could help doctors see well. The first reason is; seeing blue, or green can refresh a doctor's vision of red things, including a patient's bloody bowel during surgery. If the surgeon looks at something red and pink, the surgeon becomes insensitive to it. The red signal in the brain fades, which can make it difficult to understand the nuances of the human body.
Originally, operating room attire was white to emphasize cleanliness. However, the combination of bright operating lights and an all-white environment led to eye strain for the surgeon and staff. At the same time, it is also mentioned that white clothes are worn as a symbol of peace. It is also believed that after coming to the hospital, the patient can stay positive in a stressful environment, that is why doctors always wear white coats.
Red can lead to distracting green illusions on white surfaces. However, this still doesn't explain why surgeons chose green and blue as the primary colors for their scrubs and not purple or yellow.
Which also helped centralized laundries from mixing up different institutions linnens . Most scrubs in operating rooms remain blue or green today, however, some facilities have gone so far as to have scrubs in an obnoxious pink color, which helps to lessen the impact of scrubs 'walking off'. Often you all have seen a doctor wearing green or blue clothes in movies or in the hospital. Usually, such clothes are worn by a doctor when someone has to do an operation.
Originally designed for use by surgeons and other operating room personnel, who would put them on when sterilizing themselves, or "scrubbing in", before surgery, they are now worn by many hospital personnel. This is the reason that from the curtains to the clothes of the employees in the hospitals are green or blue, so that the eyes of the patients coming and staying in the hospital are relaxed, they do not have any problem. Because of this, the green and blue colours of their clothes not only help to improve a surgeon's visual acuity but also make them more sensitive to different shades of red.

Concrete Drying Time: Importance of Following Manufacturer Guidelines
When it comes to working with concrete, one of the most crucial factors to consider is the drying time. Not following the manufacturer's guidelines for the drying time of concrete can lead to a variety of problems, including structural issues and decreased durability. In this article, we will explore the importance of adhering to the recommended drying time provided by the manufacturer to ensure a successful concrete project.
Understanding Concrete Drying Time
When working with concrete, it is important to understand the concept of drying time. The drying time refers to the period it takes for the concrete to fully cure and reach its maximum strength. This process is crucial for the overall durability and longevity of the concrete structure.
Factors Affecting Concrete Drying Time
Several factors can affect the drying time of concrete. These include environmental conditions such as temperature, humidity, and air circulation. The type of concrete mix, thickness of the slab, and additives used can also impact the drying time. It is essential to consider these factors when planning a concrete project to ensure proper curing and strength development.
Importance of Proper Drying Time
Proper drying time is essential for the structural integrity of the concrete. Failure to allow the concrete to dry fully can result in cracking, spalling, and other forms of damage. Following the manufacturer's guidelines for drying time is crucial to ensure the concrete reaches its full strength and durability. It is also important for the overall aesthetics of the concrete surface, as a rushed drying process can lead to discoloration and uneven finishes.
Common Mistakes in Estimating Drying Time
One common mistake in estimating drying time is underestimating the impact of environmental conditions. Factors such as high humidity or low temperatures can significantly slow down the drying process. Another mistake is assuming that all concrete mixes have the same drying time, when in reality, different mixes can have varying curing requirements. It is important to carefully follow the manufacturer's guidelines and take into account all relevant factors to accurately estimate drying time for a concrete project.
Manufacturer Guidelines for Concrete Drying Time
When it comes to working with concrete, one of the most important factors to consider is the drying time. Following the manufacturer guidelines for concrete drying time is crucial to ensure the strength, durability, and longevity of the concrete structure.
Overview of Manufacturer Guidelines
Manufacturer guidelines for concrete drying time typically include information on the ideal conditions for drying, such as temperature, humidity, and air circulation. They also provide recommended drying times based on the type of concrete used and the thickness of the pour. Following these guidelines ensures that the concrete cures properly and reaches its maximum strength.
Benefits of Following Guidelines
There are several benefits to following manufacturer guidelines for concrete drying time. Firstly, it helps to prevent cracks and other structural issues that can arise from improper drying. By allowing the concrete to dry at the recommended rate, you can ensure that it reaches its full strength and durability. Additionally, following guidelines can help to avoid costly repairs and maintenance down the line.
Consequences of Ignoring Guidelines
On the other hand, ignoring manufacturer guidelines for concrete drying time can have serious consequences. If the concrete is not allowed to dry properly, it may not reach its full strength, leading to a weakened structure that is more prone to damage. Cracks, spalling, and other issues can also occur if the concrete dries too quickly or too slowly. In extreme cases, ignoring guidelines can even result in structural failure, posing a safety risk to occupants.
In conclusion, following manufacturer guidelines for concrete drying time is essential for ensuring the quality and longevity of a concrete structure. By understanding and adhering to these guidelines, contractors can avoid costly mistakes and create a durable, long-lasting finished product.
Tips for Monitoring and Ensuring Proper Drying Time
When it comes to ensuring that concrete dries properly, there are a few key tips to keep in mind. By following these guidelines, you can help prevent issues such as cracking, uneven drying, and other problems that can arise when concrete is not allowed to dry properly.
Use of Moisture Meters
One of the most effective ways to monitor the drying time of concrete is by using moisture meters. These handy tools can provide you with accurate readings of the moisture content in the concrete, allowing you to determine when it has reached the appropriate level of dryness. By regularly checking the moisture levels with a moisture meter, you can ensure that the concrete is drying at the right pace and avoid any potential problems.
Temperature and Humidity Considerations
Temperature and humidity play a crucial role in the drying time of concrete. It's important to monitor these factors closely to ensure that the concrete is drying at the optimal rate. In general, warmer temperatures and lower humidity levels will help the concrete dry faster, while cooler temperatures and higher humidity levels can slow down the drying process. By keeping an eye on these environmental factors and making any necessary adjustments, you can help ensure that the concrete dries properly and without any issues.
Importance of Curing Methods
Proper curing is essential for ensuring that concrete reaches its maximum strength and durability. There are various curing methods available, including wet curing, membrane curing, and curing compounds. Each method has its own advantages and is suitable for different situations. By following the manufacturer's guidelines and selecting the appropriate curing method for your project, you can help ensure that the concrete dries properly and achieves the desired strength and durability.
By following these tips for monitoring and ensuring proper drying time, you can help ensure that your concrete dries correctly and without any issues. Properly dried concrete will be stronger, more durable, and less likely to experience issues such as cracking or uneven drying.
In conclusion, following the manufacturer guidelines for concrete drying time is essential to ensure the longevity and durability of the structure. By allowing the proper amount of time for the concrete to cure, you can prevent cracking, weakening, and other issues that may arise if the guidelines are not followed. It is important to prioritize patience and precision in this aspect of construction to guarantee a solid and reliable finished product. Remember, taking shortcuts in the drying process can lead to costly repairs and compromises in the structural integrity of the concrete. Trusting and adhering to the recommendations of the manufacturer is crucial for the success of any concrete project.

A medieval village in Germany faces destruction because of plans to expand coal production.
Atterwasch, near the country's border with Poland, is around 700-years-old. Its residents and those of neighbouring villages want to stop coal producers from uprooting their communities.
Environmentalists also oppose increased coal use, as it is has higher emissions levels than other forms of energy.
Al Jazeera's Nick Spicer reports from Atterwasch near Germany's border with Poland.

 5. A solvent or thinner
 6. A drier
 1. It is generally, metallic oxide and is used in the form of powder.
 2. It a pigment that forms the chief ingredient of paint.
 3. The most important purpose of adding a base in paint is to make an opaque(non-transparent) coating to hide the surface to be painted.
 4. It provides resistance to abrasion and prevents shrinkage cracks likely to be formed in the film, during drying.
 5. White lead, red lead, zinc oxide, iron oxide, and titanium whites are the bases commonly used.
Inert filler or extender

Resolve Transactions Manually
Updated: April 11, 2008
Applies To: Windows Server 2008
Occasionally, you may have to force transactions to commit or abort to release locks and make database resources available to other network users and applications. You can use this procedure and the Component Services snap-in to resolve transactions manually.
Membership in Administrators, or equivalent, is the minimum required to complete these procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (_URL_
 1. Open the Component Services snap-in.
 To open Component Services, click Start. In the search box, type dcomcnfg, and then press ENTER.
 2. In the console tree, double-click the computer (such as My Computer for the local computer) for which you want to view the transaction list.
 3. Double-click the Distributed Transaction Coordinator folder, and then locate the DTC for which you wish to resolve transactions manually.
 - To select the local DTC instance, click to open Local DTC, and then click Transaction List.
 - To select a clustered DTC instance, click to open Clustered DTCs, locate the clustered DTC by name, click to expand its contents, and then click Transaction List.
 4. In the details pane, right-click the transaction that you want to resolve; point to Resolve; and then click Commit, Abort, or Forget.
The In Doubt state indicates that the transaction is on a subordinate Distributed Transaction Coordinator (DTC) and that the superior DTC is not accessible. In this situation, we recommend that you verify the connection between the computers that are involved in the transaction. First, verify network connectivity between the two computers, and, if there is a firewall involved, verify that an exception for the DTC is enabled on the firewall. For more information, see Enable Firewall Exceptions for MS DTC.
The In Doubt state indicates that a transaction is managed by a different DTC. The transaction is prepared, but a commit or abort decision is not received yet, indicating that the coordinating DTC is not accessible. You can force a transaction in this state to either commit or abort, using the following procedure to resolve the transaction manually.
In this situation, we recommend that you verify the connection between the computers. First, verify network connectivity between the two computers, and if there is a firewall involved, verify that an exception for the DTC is enabled on the firewall. For more information, see Enable Firewall Exceptions for MS DTC.
 1. Use the Transaction List to locate the in-doubt transaction's immediate parent. For information about viewing transaction properties, see View Transaction Information.
 2. Locate the superior DTC system. To do this, you need to know the topology for the application that is using the transaction. Use the Transaction List on that computer where the superior DTC is running to determine the outcome of the in-doubt transaction, as follows:
 - If the transaction does not appear on the Transactions page, the transaction has been aborted and you can abort the transaction on the subordinate system manually.
 - If the transaction appears on the superior DTC system as Cannot Notify Commit, the transaction has committed and you can commit the transaction on the subordinate system manually.
 - If the transaction appears on the superior DTC system as Cannot Notify Abort, the transaction has aborted and you can abort the transaction on the subordinate system manually.
 - If the transaction is shown as In Doubt on the superior DTC system, use the Transactions page on that system to locate the transaction's next immediate superior. Continue to follow the transaction up the commit tree until you locate the superior system on which the transaction is not shown (indicating that it aborted), is in the Cannot Notify Abort state (indicating that it aborted), or is in the Cannot Notify Commit state (indicating that it committed). If the transaction is aborted on the superior DTC system, manually force the transaction to abort on that computer's immediate subordinate. If the transaction is committed on the superior system, manually force the transaction to commit on the subordinate system. Follow this method all the way down the transaction tree until all transactions are resolved.
 3. When you have either manually committed or manually aborted the transaction on the subordinate system, manually force the immediate superior to forget the transaction. This deletes the transaction from its local Microsoft Distributed Transaction Coordinator (MS DTC) log file.
The Cannot Notify Abort state indicates that the transaction has aborted but that a subordinate transaction manager has not been notified of the transaction's outcome. You can use the following procedure to resolve the transaction manually.
CautionCaution
Do not manually forget a transaction until all subordinate DTCs have been notified of the transaction outcome. Otherwise, the result might be corruption or loss of transaction related data.
 1. Open the Component Services snap-in, and navigate to the transaction list for the transaction in question. For more information, see the procedure "To resolve transactions manually" earlier in this section.
 2. In the Transaction List dialog box, right-click the transaction that is in the Cannot Notify Abort state. This displays the superior DTC and subordinate transaction managers for the transaction.
 3. After you locate the subordinate transaction managers, force the transaction to abort on each of the subordinate systems.
 4. When you have manually aborted the transaction on all subordinate systems, return to the DTC that shows the transaction in the Cannot Notify Abort state, and then force that DTC to forget the transaction.
The Cannot Notify Commit state indicates that the transaction has committed but that some subordinate DTC transaction managers or resource managers have not been notified of the transaction's outcome. You can use the following procedure to resolve the transaction manually.
CautionCaution
Do not manually forget a transaction until all subordinate DTCs have been notified of the transaction outcome. Otherwise, the result might be corruption or loss of transaction related data.
 1. Open Component Services and navigate to the transaction list for the transaction in question. For more information, see the procedure "To resolve transactions manually" earlier in this section.
 2. In the Transaction List, right-click the transaction that is in the Cannot Notify Commit state. This displays the superior DTC and subordinate transaction managers for the transaction.
 3. After you locate the subordinate transaction managers, force the transaction to commit on each of the subordinate systems.
 4. When you have manually committed the transaction on all subordinate systems, return to the DTC that shows the transaction in the Cannot Notify Commit state, and then force that DTC to forget the transaction.
 noteNote
 There can be more than one computer operating as a subordinate DTC. Make sure to manually resolve the transaction on all subordinates before you force the superior system to forget the transaction.

Orbital Welding Is Widely Used In Different Industries
Orbital welding is a specialized kind of welding. Many essential industries used this kind of welding process. Orbital welding virtually replaced the manual type of welding. orbital weldingThe process is more favored in highly specialized industries because the results are very neat, much more precise, and it is highly efficient.
The term 'orbital welding' pertains to the method of joining tubular objects together. There are several unique challenges when it involves the orbital welding method. It is different as compared to the traditional flat welding because the materials involved are totally different, different tools are required, and the amount of complication in the welding process. It needs a very trained welder to do the job.
Why Orbital Welding Is Different?
Orbital welding tools are distinct in their function and type. In orbital welding, tubes and pipes are put together in order that movement is eliminated. A device referred to as an orbital weld head rotates an electrode within the welded area to make the desired results. Weld heads are readily available in various sizes, styles, and shapes. A different kind of weld head is usually used if there are area restrictions and if there is a particular part to be welded.
If the area has more surface, the more heat is needed to finish a successful weld. Therefore, larger tube and pipe diameters need a great deal of heat and energy to weld. That is why weld heads with a cooling mechanism are very popular by welders. Companies like this cooling feature since it permits for a better work without having discomfort, wear, and much safety.
Orbital welding could sound new to you but there are a variety of functions and comforts that you merely enjoy every day without learning that orbital welding has made it possible. Gas and fluid distribution on your property is a good example that is something not possible without orbital welding. In the construction industry, numerous metals have special challenges when it involves orbital welding. But, a well-trained welder even though it is a difficult material to weld like alloy and alternative precious metals will be handled and effectively welded.
Orbital Welding In Different Industries
Welding a pipe that will be distributed throughout a home or business is offered with utmost importance because it is handling gas products. When safety is jeopardized, it might threaten people and property if the work is not correctly done. Oxygen analyzers are sometimes used to ensure that the oxygen content is low enough to give a weld and in just specific limits so that no likelihood of a gas leak or other malfunction might occur.
The food, dairy and beverage industries need to have orbital welding on all weld joints. Most of their piping equipment has regular schedules for cleaning as well as sterilization. Their piping system should be extremely clean and smooth as possible because any imperfect weld joint can be a placed where bacteria can get in and develop. In pharmaceutical industries they need their piping system to deliver high quality water to be used in their various procedures. This will need orbital welding to ensure a supply of water from the tubes is not infected by bacteria, rust or different impurities.

The crest is the official signature of The United Church of Canada, placed on legal documents, ordination and commissioning certificates, and licences to perform the sacraments. Designed by the Rev. Dr. Victor T. Mooney (a treasurer of the United Church), it was officially adopted in 1944 by the 11th General Council.
For our church members, this insignia is a spiritual and historic reminder. Its oval shape is derived from the outline of a fish, a symbol of identity by early Christians. The initials of the words "Jesus Christ, Son of God, Saviour" spell the Greek word for fish.
The crest is designed in the form of a St. Andrew's Cross with an insignia in each of the four corners. The "X" at the centre, the first letter of the Greek word for Christ, is a traditional symbol for Christ. In the four corners of the crest are symbols, three of which are particularly associated with the three communions—Congregational, Methodist, and Presbyterian—that united to form The United Church of Canada in 1925.
- The open Bible represents the Congregational Churches with their emphasis upon God's truth that makes people free. From this communion we have a heritage of liberty in prophesying, love of spiritual freedom, awareness of the creative power of the Holy Spirit, and clear witness for civic justice.
- The dove is emblematic of the Holy Spirit (Mark 1:10) whose transforming power has been a distinctive mark of Methodism. Here our heritage is one of evangelical zeal, concern for human redemption, warmth of Christian fellowship, the testimony of spiritual experience, and the ministry of sacred song.
- The burning bush is the symbol of Presbyterianism. It refers to the bush that burned and was not consumed (Exodus 3:2), and symbolizes the indestructibility of the church. From Presbyterianism we have received a heritage of high regard for the dignity in worship, the education of all people, the authority of scripture, and the church as the Body of Christ.
- The symbols alpha and omega in the lower quarter are the first and last letters of the Greek alphabet. They symbolize the eternal living God, in the fullness of creation (Revelation 1:8).
The Latin words ut omnes unum sint that surround the symbols on the crest mean That all may be one and are taken from John 17:21. They are a reminder that we are both a "united" and "uniting" church.
In 1980, a French translation of The United Church of Canada—L'Église Unie du Canada—was authorized by General Council to be added to the crest.
In August of 2012, at the 41st General Council, The United Church of Canada acknowledged the presence and spirituality of Aboriginal peoples in the United Church by revising the church's crest. The crest changes include incorporating the four colours of the Aboriginal medicine wheel (yellow as a symbol of life and Asian people, black as a symbol of the south and dark-skinned people of the world, red as a symbol of the west and Aboriginal peoples, and white as the colour of the north and white-skinned people) and adding the Mohawk phrase "Akwe Nia'Tetewá:neren," which means "all my relations."

Computer scientists including a team from Microsoft Research have developed a system of wearable devices that detect signs of impending emotional eating. Over four days, a test group used a phone app to log information about their mood and meals, while sensor pads in their clothing measured their breathing, sweating, and heart rate. This data enabled the researchers to predict physiological and emotional states that precede individual patterns of stress-related eating. The team is now testing bracelets to monitor users and provide interventions—possibly breathing exercises, brain teasers, or suggestions to take a walk or call a friend.

Native Azaleas for Northern States
From "The Green Mountain Grower" No. 86, November 77
Dr. N. E. Pellett, Editor
Dept. of Plant and Soil Science
University of Vermont, Burlington, Vermont
Several deciduous azaleas native to the eastern United States have potential for wide landscape use in Vermont. Rhododendron roseum, popularly known Mountain Pink is native in southern regions of Vermont, occurring as far north as Johnson. Admirers familiar with its colorful pink flowers often ask nurserymen for this plant. Unfortunately it is not commonly available in the trade. Other native deciduous Rhododendron species potentially useful in Vermont include flame azalea, R. calendulaceum; swamp azalea, R. viscosum; pinkshell azalea, R. vaseyi; rhodora, R. canadense and R. arborescens. The Vermont Agricultural Experiment Station has received a grant from the U. S. D. A. Plant Introduction Station to collect native azaleas and rhododendrons with potential for cold regions. Seeds or superior selections of eastern species are being collected from native stands in the northernmost or coldest part of their range.
Small samples of seed are available to experiment stations, Arboreta and Vermont nurserymen. Seeds available now include:
Rhododendron roseum from Lake Dunmor near Brandon.
R. viscosum from near Amherst, Mass.
R. canadense from near Island Pond.
Kalmia latifolia from near Brattleboro.
The following procedure is recommended for seed propagation of native azaleas:
January - Start seeds under fluorescent lights (16 hr day). Sow seeds on pressed surface of pre-moistened shredded sphagnum moss. Carefully sprinkle with water. Cover with polyethylene or glass and put under lights at 70°F. When seeds germinate remove cover & plant so plants are within 6" of lights. As plants develop, fertilize regularly with a dilute fertilizer solution (i.e., ½ tsp of Rapid-gro in 1 gallon at every watering). Plants can be grown in the greenhouse, but plants need long days to continue growth.
March - When seedlings range from 1 to 2" tall, transplant into individual pots or flats. The following soil media has given good results:
peat; perlite 1:1, per cubic ft. of soil, mix in:
Gypsum, 3 tablespoons Epsom salts, 3.5 teaspoons
Fritted trace elements, ½ tsp.
Continue to fertilize plants regularly.
If they show chlorotic foliage, use an acid-reacting fertilizer. Pinching the terminal of new growth will promote branching.
June - Plants should be six inches tall, branched and ready to line out in field rows or grown on as container plants out-of-doors. Plants should be saleable the following spring.

This is another daft claim. It is daft for the same reason as Cassidy's explanation for glim is daft. When people borrow between languages, they tend to borrow individual words. Occasionally they borrow well-known and often-used phrases. However they never borrow random bits of sentences and they borrow the most basic form of the word. Cassidy claims that 'beef' as in 'to have a beef with someone' comes from the Irish phrase b'aifirt which means (if it means anything) 'was a reproach'. On its own and out of any context like this, it really means nothing and it would be pronounced baffirch, which doesn't sound much like beef.
The origins of the slang term 'beef' (complaint) are not known. There are various suggestions involving disputes between sheep-herders and cow-punchers in the old west or soldiers complaining about their rations in the Civil War. However, 'beef' doesn't come from b'aifirt and that's a fact.

||Overview of Construction and Trade
The construction industry, a business that constantly requires apprenticeships and traineeships, is made up of skilled contractors and qualified technicians who manage building, electrical, carpentry and construction projects.
Construction and trade courses offer various levels of specialisations and specific training in construction and trade-related jobs such as building, carpentry, welding and electrical installation.
Studying Construction and Trade
The most common construction and trade career path is to undertake an apprentice course that will provide real work experience in a company. Popular courses include electrical apprenticeships, building apprenticeships and plumbing apprenticeships, which are offered by registered training organisations and Technical and Further Education (TAFE) institutions.
Building, construction, carpentry and electrical courses are usually offered as six months to two years courses. These involve on-the-job training, where students undertake work experience in a construction or trade company.
The basic requirements for entry to a construction and trade (carpentry, building, electrical or welding) certificate and diploma programme would be a pass in Mathematics, Physics and English.
Students with their construction certificate or trade qualification seeking higher education pathways can undertake a three to four-year degree in applied science, building and construction or architecture courses, which covers areas such as construction management, building design and surveying, or electrical engineering.
Careers in Construction and Trade
Accreditation and licensing certifications are required for certain jobs in the construction and trade industries, including builders, electricians and construction managers.
Accredited assessments centres will assess and issue the rights for a certified individual to practice in the construction and trade industries after a series of tests and short courses.
Trade industries offer specialised technical services such as mechanical, electrical and plumbing in construction projects. Construction and trade jobs also involve the maintenance of facilities for commercial and residential purposes.
Some of the construction and trade jobs that you can undertake, depending on your specialisation and qualification, include being a builder, carpenter, bricklayer, electrician, plumber or welder. You can also be a construction manager or project manager if you have the right qualification and experience.
Different Australian states may have varying accreditation standards for the construction, building and electrical professions, so it is important to check on the required license in your intended place of practice versus the location of where you have obtained your assessment qualification.?
Skills needed in Construction and Trade
Occupational, health and safety knowledge is a prerequisite for construction and trade jobs. An overall clean bill of health is also required as the job will involve physical strength, and being on your feet for long stretches.
Project management and strong communication skills are also useful, as construction and trade jobs require interacting with clients, suppliers and sub-contractors for a turnkey project.

Octopus Deploy Documentation
Build versions and packaging in Team Build
Last updated
Correctly versioning the packages you deploy with Octopus Deploy is important so the right version gets deployed at the right time. With Azure DevOps and Team Foundation Server (TFS), specifying a package version isn't always straightforward.
This guide shows you how best to version your builds and packages in Azure DevOps and TFS, whether you're using OctoPack, or the Octopus Extension in the Visual Studio Marketplace.
Build numbers in Team Build
In Team Build (the build system in Azure DevOps and TFS), build numbers may be in a format that doesn't represent a valid SemVer number.
For example, Microsoft's Build Number format documentation gives an example: $(TeamProject)_$(BuildDefinitionName)_$(SourceBranchName)_$(Date:yyyyMMdd)$(Rev:.r) will result in a version number like Fabrikam_CIBuild_master_20090805.2.
While this is a valid Team Build build number, it can cause issues when trying to pack the build output into a NuGet package or zip file for Octopus.
Packages used by Octopus must conform to SemVer 1.0 or 2.0 depending on the version of Octopus you're using.
The link above explains versioning in detail, but in its simplest form it means two things:
 1. Numbered versions in 3 or 4 segments that can be interpreted as major.minor.patch, with an optional "prerelease tag" afterwards in the form -tag.
 2. Versions can be sorted predictably. For example, 1.2.3 is newer than 1.2.0.
As you can see, a package version of Fabrikam_CIBuild_master_20090805.2 won't be valid will cause issues!
Setting a SemVer-compliant build number
The recommendations below generally rely on the build number itself being SemVer compliant. To do this, you can change the build number format.
Our recommended build number format is: x.y.$(BuildID) where x and y are integers. You can change them when you want to bump a version. This format will produce a three-part version number like 1.2.350.
Recommended Build format
If you have a build for a separate branch, it's a good idea to add the version tag. For example: x.y.$(BuildID)-feature-1 will produce a version number like 1.2.350-feature1. Even better, you can use the $(Build.SourceBranchName) variable to set it to the branch name.
The only downside of this numbering format is the $(BuildID) variable always increases, and does so at the Project Collection level. That means it doesn't reset when you increment your major and minor versions, and if you have multiple builds in your Collection, numbers will be skipped.
Other extensions such as gitversion can also be used to easily get SemVer compliant build numbers.
Packaging in Team Build
There are two standard ways to package your build output in Team Build. The first is to use OctoPack, and the second is to use the build tasks in the Octopus marketplace extension.
You can mix and match these two methods. For example, you might prefer to use OctoPack and the /p:RunOctoPack MS Build argument, but then use the Push and Create Release tasks from the extension.
Octopack and.NET Core
Octopack is not compatible with.NET core and we suggest using the extension instead.
Versioning when using OctoPack
Unless told otherwise, OctoPack will attempt to set the package version itself. You can see exactly how it tries to find a version on this documentation page.
More often than not, the version number will come from the [assembly: AssemblyVersion] attribute found in the AssemblyInfo.cs file (usually in the Properties folder of your project).
The assembly version number doesn't always behave the way we want. It may not change, and if it does, it may not change sequentially.
Setting the AssemblyVersion number to x.y.* will fix the two most common problems here. A version like 1.0.* will result in an always-increasing version number.
 1. If the version number is fixed (e.g., Octopus will complain that the package number already exists.
 2. If the version number only changes "revision" number (e.g. 1.0.0.*), numbers can repeat.
One problem remains - particularly for web projects. If you only change content files, triggering a new build won't update the version number because Team Build realizes no compilable code has changed. OctoPack won't get a new version number!
OctoPack recommendation
To solve all these issues, we recommend using the /p:OctoPackPackageVersion argument when using OctoPack. This lets you specify the version directly, and you can use build variables to specify the version number.
 1. Set the build definition build number format (described above) to a valid SemVer version.
 2. Add the appropriate /p:OctoPackPackageVersion MSBuild argument:
 - In the new build engine (Azure DevOps and from TFS 2015 onwards): /p:OctoPackPackageVersion=$(Build.BuildNumber)
 - In the older XAML-based builds: /p:OctoPackPackageVersion=$(TF_BUILD_BUILDNUMBER). You may also need to do some extra work for certain build definitions.
You can use the additional MSBuild arguments for OctoPack to give yourself more control over the packaging process.
Versioning when using the Octopus build tasks
If you're using the new Octopus Deploy extension from the Visual Studio Marketplace, you'll have access to a new Package Application build task.
Package application build task
This task does not provide you with a default version number - this is something you have to set yourself. Clearly it wouldn't be feasible to change this value every time you do a build, so we recommend you make use of the build variables that Team Build provides.
Build and Release variables can be found in the Microsoft Documentation, but the more useful ones include:
 - $(Build.BuildNumber) - This is the full build number (see above for setting an appropriate format).
 - $(Build.BuildID) - This is a unique, incrementing ID at the Project collection level. Every new build will give you a new number.
 - $(Build.SourceBranchName) - this is the last path segment in the name of the branch. For example, a branch of refs/heads/master will return master.
Build task recommendation
There are two options we recommend for specifying a version number to the Package Application task.
 1. Use a combination of static values and variables directly. For example, 1.0.$(Build.BuildID) will always give you a new version number.
 2. Use the full build number, and format that number appropriately as described above.
We recommend the second option for a few reasons.
First, it's very easy to match the build to the package because they'll have the same number, and secondly, if you have multiple pack steps, you only need to change a single version number.
Specifying the files to pack and push
One of the frequent causes of issues when using the Octopus build tasks is properly specifying the folders to pack and the NuGet package to push. Especially if you're using the hosted build server, it can be hard to figure out where everything ends up when the build is running.
Rather than guessing, it can be helpful to specify these folders specifically. Again, there are some useful build variables you can make use of.
 - $(Build.SourcesDirectory) - the location of your source before it gets built.
 - $(Build.ArtifactStagingDirectory) - A staging location for artifacts - useful for output files you want to use later (e.g. Nuget files).
 1. Use the /p:outdir= MSBuild argument in your compile step to specify where the compiled code should end up.
 2. In the Package Application step, put the location from step 1 into the Source Path field.
 3. In the Package Application step, put a new location into the Output Path field.
 4. In the Push Package(s) to Octopus step, specify the full path and filename from step 3 above.
By way of example, here's a nicely-configured set of build, pack, and push steps.

You have a crjewelryeautiful piece of jewellery with transparent resin, but you're worried that it might turn yellow over time.
How can you prevent that? This is a question I'm asked a lot by people who are starting out in resin jewelry making, so I'll answer it here in detail.
Here's everything you need to know about keeping your clear epoxy from turning yellow and looking like old cheese:
How do you keep transparent resin from turning yellow?
- Wash your hands, the resin container, and all tools with soap and warm water before you begin. A clean workspace is a great way to start.
- Cure the resin under UV light to clear it as soon as possible after pouring.
Does transparent resin yellow?
The answer is yes and no. It depends on what type of resin you're using and whether or not you use a UV light when curing it.
- If the clear resin you're using has a blue colorant in it, then no matter what, it'll turn yellow over time. This is because the yellowing occurs as a result of exposure to sunlight (both natural sunlight and artificial UV lights).
How do you clean transparent resin?
- Use a toothbrush and soap.
- Use a toothbrush and baking soda.
- Use a toothbrush and vinegar.
- Use a toothbrush and lemon juice.
- Use a toothbrush and hydrogen peroxide (3% solution).
- Use a toothbrush and rubbing alcohol (isopropyl or 70% solution).
- You can also use: water, salt, baking powder or baking soda, and dishwashing liquid with bleach added (1 part bleach to 4 parts dishwashing liquid)
Can you print clear resin?
Yes, you can print with clear resin.
There are three main types of 3D printers that can be used to print in clear resin: SLA printers, DLP printers, and resin printers. Each type has its own pros and cons but they all work similarly enough to be explained in one article!
What resin does not turn yellow?
You can prevent yellowing in resins that have a low viscosity and are exposed to UV light. This includes polyester, epoxy, and polyurethane resins.
Polyester resin is a common clear resin with good clarity and impact strength that doesn't yellow when exposed to direct sunlight; however, it will yellow over time in indirect sunlight (think of the sun through clouds).
Epoxy resin is another common clear resin with good clarity, but it's more expensive than polyester resins and also yellowed when exposed to direct sunlight (and indirect).
Polyurethane is another type of clear resin that doesn't turn yellow when exposed directly or indirectly
Why is my epoxy turning yellow?
If your epoxy is turning yellow, it's not because of the resin. If it were, the whole batch would be affected, and that's not usually the case. Here are some of the most common reasons why epoxies turn yellow:
- Your vinyl has a UV inhibitor in it, so when exposed to sunlight or even fluorescent bulbs (which emit UV radiation), your resin will turn yellow over time as a result of this pigment. If you see this happening in just one area of your project, then it may be that only that particular piece was laminated with a vinyl-containing inhibitor. In most cases though, if there's anything at all on hand that can prevent this from happening then use it!
- You used a base coat for your project rather than just dipping into a clear coat or brushing on clear paint alone because… well… why would you do that? Anyway – back up! You've got yourself an entire "tinting" issue going here which can easily be solved by switching out colors again to something more appropriate like black instead of blue or red instead of orange etcetera…
How long before resin turns yellow?
It depends on a few things:
- The resin itself. Some resins are more yellowing than others. If you're using a particularly yellowing resin, it will probably turn a more golden color faster than other types of resin would.
- The cure time and temperature of your curing process. If you're using an oven or heat gun to cure your resin, the higher the temperature and longer the exposure time (i.e., how long it takes to get from room temperature to full cure), the greater chance that any impurities in your clear resin will start reacting with one another as they come together during the thermal bonding process, which can result in discoloration over time (this also applies when drying out too slowly). This is why it's so important to use quality materials when making jewelry pieces!
- Whether or not there are any impurities present inside your mix before its cured state comes about; if so then this would mean that these particles will actually cause direct damage to them once they reach their hardened state through thermal bonding processes during curing times for example when using an oven or heat gun technique methodologies like those listed above."
How do you polish resin by hand?
- Use microfiber cloths. Microfiber cloths are very effective at removing fingerprints and dust from resin, particularly if they're dampened with water first.
- Use polishing compounds. Compounds are used to help remove stubborn dirt or stains from resin items that have been stained by food or drink spills in the past, as well as other substances such as ink and grease. They can be applied using a buffing wheel on your electric drill if you want to go all out; otherwise, it can also work well with a soft rag or cloth by hand (but make sure not to get any residue on any part of your body).
- Use buffing pads when needed for hard-to-remove stains like lipstick marks or grease stains from cooking utensils like spatulas (they won't work for everything). These can be found at most hardware stores such as Home Depot—they look like dish scrubbers with loops of metal wire sticking out between each loop instead of foam padding—and sometimes come included with kits sold specifically targeted toward cleaning up after working with acrylic paints so keep an eye out!
In conclusion, keeping transparent resin from yellowing is a bit of a balancing act. If you want to maintain the integrity of your work and prevent it from becoming discolored over time, then follow these simple tips: don't let your resin sit for too long in direct sunlight or leave it out in extreme temperatures (like heat/cold).

Alone: India's Farmer WidowsIndia's ongoing water crisis has driven 200,000 farmers to suicide. As water dwindles, that number grows, and farmer widows are left to pick up the pieces.
Over the past decade, India has been gripped by a devastating water crisis. Farmers make up an estimated 70 percent of the country's population, and for them the consequences of the drought have been dire: Overwhelmed by chronic lack of water, failed crops, and growing debts, more than 200,000 farmers have committed suicide since 1997.
Their families often find them either hung or poisoned by pesticides they've chosen to ingest. The widows left behind struggle to support their children, working as landless laborers for as low as 100 rupees ($2) a day and battling creditors that come to collect money they claim to have lent their husbands. This slideshow features portraits of widows from Maharashtra, one of the three most suicide-ridden states in the nation. They represent only a fraction of the hundreds of thousands left behind.


# INSERT
# INSERT, ON DUPLICATE KEY UPDATE
INSERT INTO 'table_name'
 ('index_field', 'other_field_1', 'other_field_2')
 VALUES
 ('index_value', 'insert_value', 'other_value')
 ON DUPLICATE KEY UPDATE
 'other_field_1' = 'update_value',
 'other_field_2' = VALUES('other_field_2');
This will INSERT into table_name the specified values, but if the unique key already exists, it will update the other_field_1 to have a new value.
Sometimes, when updating on duplicate key it comes in handy to use VALUES() in order to access the original value that was passed to the INSERT instead of setting the value directly. This way, you can set different values by using INSERT and UPDATE. See the example above where other_field_1 is set to insert_value on INSERT or to update_value on UPDATE while other_field_2 is always set to other_value.
Crucial for the Insert on Duplicate Key Update (IODKU) to work is the schema containing a unique key that will signal a duplicate clash. This unique key can be a Primary Key or not. It can be a unique key on a single column, or a multi-column (composite key).
# Inserting multiple rows
INSERT INTO 'my_table' ('field_1', 'field_2') VALUES
 ('data_1', 'data_2'),
 ('data_1', 'data_3'),
 ('data_4', 'data_5');
This is an easy way to add several rows at once with one INSERT statement.
This kind of 'batch' insert is much faster than inserting rows one by one. Typically, inserting 100 rows in a single batch insert this way is 10 times as fast as inserting them all individually.
# Ignoring existing rows
When importing large datasets, it may be preferable under certain circumstances to skip rows that would usually cause the query to fail due to a column restraint e.g. duplicate primary keys. This can be done using INSERT IGNORE.
Consider following example database:
SELECT * FROM 'people';
--- Produces:
+----+------+
| id | name |
+----+------+
| 1 | john |
| 2 | anna |
+----+------+
INSERT IGNORE INTO 'people' ('id', 'name') VALUES
 ('2', 'anna'), --- Without the IGNORE keyword, this record would produce an error
 ('3', 'mike');
SELECT * FROM 'people';
--- Produces:
+----+--------+
| id | name |
+----+--------+
| 1 | john |
| 2 | anna |
| 3 | mike |
+----+--------+
The important thing to remember is that INSERT IGNORE will also silently skip other errors too, here is what Mysql official documentations says:
Data conversions that would trigger errors abort the statement if IGNORE is not > specified. With IGNORE, invalid values are adjusted to the closest values and >inserted; warnings are produced but the statement does not abort.
Note :- The section below is added for the sake of completeness, but is not considered best practice (this would fail, for example, if another column was added into the table).
If you specify the value of the corresponding column for all columns in the table, you can ignore the column list in the INSERT statement as follows:
INSERT INTO 'my_table' VALUES
 ('data_1', 'data_2'),
 ('data_1', 'data_3'),
 ('data_4', 'data_5');
# Basic Insert
INSERT INTO 'table_name' ('field_one', 'field_two') VALUES ('value_one', 'value_two');
In this trivial example, table_name is where the data are to be added, field_one and field_two are fields to set data against, and value_one and value_two are the data to do against field_one and field_two respectively.
It's good practice to list the fields you are inserting data into within your code, as if the table changes and new columns are added, your insert would break should they not be there
# INSERT with AUTO_INCREMENT + LAST_INSERT_ID()
When a table has an AUTO_INCREMENT PRIMARY KEY, normally one does not insert into that column. Instead, specify all the other columns, then ask what the new id was.
CREATE TABLE t (
 id SMALLINT UNSIGNED AUTO_INCREMENT NOT NULL,
 this ...,
 that ...,
 PRIMARY KEY(id) );
INSERT INTO t (this, that) VALUES (..., ...);
SELECT LAST_INSERT_ID() INTO @id;
INSERT INTO another_table (..., t_id, ...) VALUES (..., @id, ...);
Note that LAST_INSERT_ID() is tied to the session, so even if multiple connections are inserting into the same table, each with get its own id.
Your client API probably has an alternative way of getting the LAST_INSERT_ID() without actually performing a SELECT and handing the value back to the client instead of leaving it in an @variable inside MySQL. Such is usually preferable.
Longer, more detailed, example
The "normal" usage of IODKU is to trigger "duplicate key" based on some UNIQUE key, not the AUTO_INCREMENT PRIMARY KEY. The following demonstrates such. Note that it does not supply the id in the INSERT.
Setup for examples to follow:
CREATE TABLE iodku (
 id INT AUTO_INCREMENT NOT NULL,
 name VARCHAR(99) NOT NULL,
 misc INT NOT NULL,
 PRIMARY KEY(id),
 UNIQUE(name)
) ENGINE=InnoDB;
INSERT INTO iodku (name, misc)
 VALUES
 ('Leslie', 123),
 ('Sally', 456);
Query OK, 2 rows affected (0.00 sec)
Records: 2 Duplicates: 0 Warnings: 0
+----+--------+------+
| id | name | misc |
+----+--------+------+
| 1 | Leslie | 123 |
| 2 | Sally | 456 |
+----+--------+------+
The case of IODKU performing an "update" and LAST_INSERT_ID() retrieving the relevant id:
INSERT INTO iodku (name, misc)
 VALUES
 ('Sally', 3333) -- should update
 ON DUPLICATE KEY UPDATE -- 'name' will trigger "duplicate key"
 id = LAST_INSERT_ID(id),
 misc = VALUES(misc);
SELECT LAST_INSERT_ID(); -- picking up existing value
+------------------+
| LAST_INSERT_ID() |
+------------------+
| 2 |
+------------------+
The case where IODKU performs an "insert" and LAST_INSERT_ID() retrieves the new id:
INSERT INTO iodku (name, misc)
 VALUES
 ('Dana', 789) -- Should insert
 ON DUPLICATE KEY UPDATE
 id = LAST_INSERT_ID(id),
 misc = VALUES(misc);
SELECT LAST_INSERT_ID(); -- picking up new value
+------------------+
| LAST_INSERT_ID() |
+------------------+
| 3 |
+------------------+
Resulting table contents:
SELECT * FROM iodku;
+----+--------+------+
| id | name | misc |
+----+--------+------+
| 1 | Leslie | 123 |
| 2 | Sally | 3333 | -- IODKU changed this
| 3 | Dana | 789 | -- IODKU added this
+----+--------+------+
# INSERT SELECT (Inserting data from another Table)
This is the basic way to insert data from another table with the SELECT statement.
INSERT INTO 'tableA' ('field_one', 'field_two')
 SELECT 'tableB'.'field_one', 'tableB'.'field_two'
 FROM 'tableB'
 WHERE 'tableB'.

Since last week, the old wall dividing the city of Nogales on the border between Arizona, USA and Sonora, Mexico is being replaced by a new one. The US government is tearing down 2.8 miles of old metal fence and building a higher, deeper fence of metal and cement posts at a cost of $11 million.
"There have always been flows of people, goods, money, and ideas back and for across the border," says Jeanette Pazos, the program coordinator at HEPAC (Home of Hope and Peace) an MCC partner organization in Nogales, Mexico, who grew up along the border.
In addition to the high-profile flows of undocumented migrants and illegal drugs going north, and illegal arms, remittances, and deportees going south, there are other smaller-scale economic exchanges taking place on a daily basis.
"American visas are highly coveted, not only by people who want to go to work in the US, but also by people who want to shop there," according to Jeanette. "A gallon of milk costs $1.58 in Nogales, Arizona, compared to $5.20 on the Mexican side. Other items like potatoes and beans are also cheaper on the US side because of American government food subsidies." Most people have a friend or relative with a visa who can go across to buy groceries for them.
On the other hand, Americans cross into Mexico for cheaper dental and medical care, perscription drugs, and real vanilla extract. Some retirement villages in Arizona have weekly bus transportation so that retired people can come to Mexico to have their hair and nails done cheaply.
The present wall was built in the mid-1990s out of sheets of recycled metal: former helicopter-landing pads discarded by the US army after use in the Persian Gulf and Vietnam wars.
Rising up 12 to 15 feet—miniature compared to the new wall which will be up to 30 feet high— the old ugly, rusted multi-coloured barrier had one advantage – it was flat and big – perfect for artist expression. Several well-known murals have been painted on the wall and there are hundreds of crosses attached to the wall. Some of these have been saved in the process of demolition.
The children of HEPAC participated in the creation of one of these murals. An artist took photos of the faces of the children to create a collage utilizing a computer program of feet walking.
Mexicans, always resourceful people, have also been close at hand during the dismantling of the old wall to get the old sheets of metal and either resell them or use them in their own house construction. "Apparently people are reselling the metal sheets for as much as 20-60,000 pesos [about $2000 to $6000]," says Jeanette.
A Latin American folk-song entitled "Punto y Raya" comes to mind when thinking about the wall.
Punto y Raya
By Anibal Nazoa & Juan Carlos Nunez
Between your people and my people, there is a point and a line,
The line says "no crossing," the point says "road closed."
This is how it is between peoples: dash and dot, dot and dash.
With so many dots and dashes, the map is like a telegram.
Walking in the world, you see rivers and mountains
jungles and deserts, but no dots or dashes.
Because these things do not exist, but rather, were drawn
so that my hunger and your hunger are always kept separated.
There are many songs about the border – this one is by Ricardo Arjona, a Guatemalan singer-songwriter, and a Tex-Mex band, Intocables:
For a weird modern version of border music, listen to the sound of the old metal wall vibrating at Security Camera 36 along the borderwall:
Original Lyrics in Spanish:
Punto y Raya (Anibal Nazoa/Juan Carlos Núñez)
Entre tu pueblo y mi pueblo / hay un punto y una raya /
la raya dice no hay paso / el punto vía cerrada.
Y así entre todos los pueblos / raya y punto, punto y raya.
/ Con tantas rayas y puntos / el mapa es un telegrama.
Caminando por el mundo / se ven ríos y montañas /
se ven selvas y desiertos / pero ni puntos ni rayas.
Porque esas cosas no existen / sino que fueron trazadas /
para que mi hambre y la tuya / estén siempre separadas.

Architecture & Engineering
Constructing a building is a complex project, both legally and technically. Consequently, architectural and engineering practice increasingly demands a sound understanding of planning, construction, and commercial law issues. Dr. Benumof works with architects and engineers to help them with the legal aspects of day-to-day architectural and engineering practice and the consequences of the many legal processes and relationships that are part-and-parcel of the construction process. Likewise, Dr. Benumof represents property owners confronted with overlapping issues of law, architecture, and engineering.


Microsoft's recommendation for troubleshooting SMTP and POP on an Exchange Server is to use protocol logs. However, logging can waste time and disk space as the logs accumulate. If you send a test message, you must go through all your logged email messages to find the message. In addition, opening the message is often time-consuming.
An alternative method I use for monitoring my Exchange server is to open Exchange System Manager (ESM) and navigate to the server that hosts the SMTP virtual server. Then, I highlight Current Sessions and hold down the F5 key. SMTP and POP connections display in the right-hand window.

Homemaker Figures were the figures used to represent people within various Homemaker sets from 1974 through 1982. They are comprised of a head piece and one of several different types of hair pieces, with the rest of the body usually built from basic System bricks.
These figures came before the minifigures. The first minifigure was released four years later in 600 Police Car in 1978. After their introduction, minifigures were used together with Homemaker figures to represent a baby or a doll.
- Some hair parts (man, woman) can be assembled in two configurations because they have two front sides, enabling to change the hair dressing with the same part (turning it). This allows, with the same part, to have both the boy and the man hair dressing, or the girl and woman hair parts. Two examples are given below:
- The arms could be made of several lengths (1 or two) because they are made of several parts. This helps to recognize adults (double length) from kids (single length).
- The arm parts have been used later for other purposes, like for the arms of 6880 Surface Explorer or the 6822 Space Shuttle. In this new usage the arms have been replaced with grippers, for instance. The colors have moved from vivid colours (blue, yellow, red) for clothes to technical colours (grey, white) for arms and technical systems.
- The head has three attachments, two on the side (ears) one on the top. Hair pieces are fixed on the two hears, hats on the top.

I have Send as permission on a mailbox. When I log on to my mailbox and send an item as the other user, why does the item appear in my Sent Items folder, not the other user's folder?
This behavior is a feature, not a bug. When you send an item, you're the person who's sending it, even if you're doing so on behalf of another user. This behavior is analogous to the way real-world systems work: If I send a fax from my fax machine, the recipient sees my fax number, even if the cover sheet says that the fax is from the president of the United States.

This paper proposes to put forward an innovative algorithm for symmetric key block cipher named as "Triple Prime Symmetric Key Block Cipher with Variable Key-Spaces (TPSKBCVK)" that employs triple prime integers as private key-spaces of varying lengths to encrypt data files. Principles of modular arithmetic have been elegantly used in the proposed idea of the cipher. Depending on observations of the results of implementation of the proposed cipher on a set of real data files of several types, all results are registered and analyzed. The strength of the underlying design of the cipher and the liberty of using a long key-space expectedly makes it reasonably non-susceptible against possible cryptanalytic intrusions.
