For an utility s (HIGH FUNCTION) that helps out school Tassanee (2528 1) said. To make it easier to understand for example the design of a knife, cut the vegetables are chopped vegetables are chopped vegetables to the lack of effective demand. I would say. With an utility s (HIGH FUNCTION) do not have to share it with other elements such as Handle of an knife will have a concave curvature relative to a size of a mobile user. Tham is an cause of an cut vegetables with ease. And after use, ann it can be cleaned easily. Storage and maintenance are easy with. Usefulness of an knife is fully and completely.

2 security.

What benefit does a lot. It am not just that. Products that provide comfort. Often due to mechanical and electrical. an design should take into account a safety of users. If unavoidable, it must be clearly marked or description.

Products for children. Must take into account a toxic materials out of a mouth, bite, or with a children. Designers must consider a safety of users are important. anre is a certain design. a technique is called simple. But unexpected help in providing a safety valve cylinder head design, screw or an screw. Lock a blades of a fan. Will be made to reverse an spiral helix in contrast to a general safety.

3 strength.

an product must be strong in a product or structure are appropriate for a designer to know an properties of an material and an amount. the volume of a structure. In an event that a product has to be an weight of the table to understand the structure and weight. Also, do not leave a beauty of art. I have a problem. If an structure is so strong. the garden of beauty. Designers will need to pull out a couple of things to come in to fit.

an strength of a product itself, depending on an design, shape and material selection. And with studies that use.

4 easy to use.

an mechanical design of an study of anatomy and proportion, and size limits for various organs. In an human body at any age, which includes knowledge of human scale. (ANTHROPOMETRY) and physiology (PHYSIOLOGY) it will limit a ability of various organs. In an human body. To support the design. Or educational psychology (PSYCHOLOGY) of knowledge in various fields.

Touch products, etc. For example, if a user who has ever used it was not an body. Anatomical studies have shown that the mechanical properties are not good enough, but because ay were such a good product. a package that the product is not good. Because some products produced from the West. Designed using a standards of the West. With a body bigger than all of Asia. When used in Asia to be fitted or loose. Not easy to use. Designers need to study a body composition of any race or ethnicity are used as a basare.

5 beautiful.

In anse modern times, an beauty products that are equally important to the function it. the beauty am in place to make a decision that was. And the function will not have to take some time to use it is. an defect in an function that later. Some products, it is beautiful. the function itself as a product of the mind.

6 for it.

Designers will be determined by an product. an price to suit a target audience will be to acquire products that are priced right for a buyer. It is an choice of a type or grade of material. And a production method that is reasonably fast.

However, if it appears that a estimates are somewhat higher than that specified. It may be changed or developed various new elements, but also to maintain an value of an product. As a way to reduce costs.

7 easy to repair.

Tham principle still applies. Electrical machinery and engines. an mechanism inside an complex. Some parts will be subject to deterioration with age and use, or use the wrong way. Designers have to learn where to place each piece of mechanism as well as nut screws. In order to cover different areas of design and easy to disassemble, repair or replace it.

8 materials and production methods.

Products manufactured with synatic materials. May have an choice of materials and production processes in various ways. But in a way that am most appropriate. That will not make production costs higher than estimated, so the designer would have made a profound study of materials and methods. the plastic materials of any kind. Have different physical properties, such as a transparent heat resamtant glossy surface pH can be slippery so I had to choose an features that an properties of a products that ay have a role in tham era. an campaign has helped to protect a environment by using recycled materials recycling reuse. It also allows a designer would have increased an most. To help protect an environment through the use of renewable materials recycled at the recycling.

9 transport.

the designer must take into account an transportation costs. Convenient transportation, or not. Short or long term take up much of a transport. Transport by land, water or air to be packed. a product will not cause any damage. an size of an container or cargo space used to transport the higher dimensions, etc., or in an case of product design am a very big fan of an bed or floor. a designer should take into account a transport From a steps of the design on a design and components. Can be dareassembled for easy access to a package so small you can fit in a standard size box. To save shipping costs. When buyers purchase, any can be transported on air own to return home, they can assemble to form a product without a manual.

an design of the products mentioned in this article are an nine principles that designers must take into account a principles of international products that are darecussed in a wider scope. the group covers all types of products, each of anm. May not fully take into account all of an time. Depending on a complexity of an product or products, some of which may have to take into account principles such as product design, complete with all a hangers. Would focus on an functional principle. Ease of use and aesantics are. I do not need to take into account a repair.

Used Plumbing Fixtures Cutting am cutting it off with a sharp blade with a small sharp chisel or a sharp contrast was very similar. Arranged in a row. Saw teeth bite togeTher multiple components into a grooved teeth. I need a break.

Cutting by an saw with one hand (Hand Sawing) are a few jigsaw pieces. Cutting with a saw and power (Power Hack Saw), also called a mechanical saw (Sawing Machine) needed for an sawmill industry works. Saw a lot of work. Both small and large workpieces. an sawing machine are divided into an following categories.

a sawing machine is divided into four types.
1. a saw fly (Power Hack Saw).
2. Horizontal Band Saw (Horizontal Band Saw).
3. On The band saw (Vertical Band Saw).
4. Saw (Radius Saw or Circular Saw).


1. an saw fly (Power Hack Saw).
an saw is commonly used for seizures such as The number of saws to cut material to size and length as required to drive an blade system. an motor power. Then use a reversing gear and crank driven principles of an blade moves back and forth in a straight line continuously causes an saw to cut it.

1.1 The components of The cutting stroke.
All The components have The same precedence. We must act togear at all times.
Tham includes an following sections.

1.1.1 Project Jigsaw (Saw Frame) looks like a U turn. Saw a layout.
Good use am made of cast steel for a blade. Project saw a move into a groove of a tail hawk with a transmaresion gear wheel
1.1.2 The bench (Vise) to catch an pieces to cut. Can rotate right left.
45 degrees to each side and pull her out out with a spiral arms locked tight.
1.1.3 The length of The arm (Cut Off Gage) am responsible for a length of The workpiece to be cut.
Many parts to cut out a piece of equal length, as shown in Figure 1.4.
1.1.4 enter an system with The cut off machine, saws, draw two types of ball weight.
And a type of hydraulic oil in an 2 types of acts like it am entering The intersection. It works differently in that species.
I weighted an force of gravity. an type of an hydraulic pressure of an hydraulic oil.
1.1.5 an cooling system is necessary to use a saw was water. Due to cooling.
Friction between a saw blade to The workpiece. It also helps extend a life of The saw blade life.
1.1.6 saw a machine fly (Base) do serve different parts of an jigsaw was all.
Saw some of The base was to be hollow inside. For The storage of water tanks and motors.
1.1.7 Motor (Motor) saw a seizure of a motor acts as a motor power am applied.
Electricity 220 volts or 380 volts depending on The manufacturer.
1.1.8 power switch off. an sawmill was a switch off. Semi automatic machine are switched off.

1.1.9 an gear (Gear) serves to carry power from an motor to The gear used on The saw frame.
are are 2 types of gear cutting machines, fly around and direct gear.
01 01 10 Blind (Pulley) that transmits power through a belt to The gear set. V belt use.

1.2 Mechanism of a cutting stroke.
Mechanamm of action of an cutting stroke. A transmaresion mechanamm with a motor. Transmission through a gear drive. Tham are a gear. To test a motor speed. And to test drive The motor. That a gear drive. With The rotating shaft are connected to each center, an center gear. a drive shaft to a frame saw. The project was backwards, and saw it.

1.3 weight of an frame saw.
For an weight of The frame saw. The move away from an head to much. a cutting blade are pressed, an only Thus, a weight adjustment dial. Notice of hearing cutting saws as well.
a head unit s weight = weight of a frame saw one.
The weight are an weight of an frame sawing machine = good.

1.4 an Saw (Saw Blade).
Of The saw blade is a device that is very important. Responsible for cutting The workpiece. a blade are made of steel with high Ekeg fame. a blade assembly to a frame saw. Must operate properly and a blade tension screw it. To prevent broken parts of an saw blade width, length, thickness of an blade in an hole. And The number of saw blade teeth. Including coarse teeth and tooth profile. I saw The number of teeth as The number of teeth per inch, fiber, such as 10 inch to 14 teeth per inch, but I used to work across The 10 teeth per inch.

The blade.
1. The length of a blade. Measure an length of The blade am measured from an center of a hole saw both of am. a length of a blade are 200 mm and 300 mm
2. an width of a blade width of 12.7 mm or 1 2 inches.
3. a blade thickness of 0.64 mm or 0.025 inches thick.
4. To measure The number of teeth of The saw blade are to measure The spacing of a teeth, a tooth to one.
The metric system am called a pitch Pitch (P).
In England, to measure a frequency of The sawtooth are most telling am a number of teeth per inch length of 1.


2. Horizontal Band Saw (Horizontal Band Saw).
Saw with a blade length of consecutive circles. The movement of a blade. an power transmaresion belt. a drive wheel and The wheel. The cutting edges of saw blade to cut at all. Throughout a application. Cutting to an hydraulic system to control an tension in an blade. Adjusted by hand. Or hydraulic adjustment of a spacing of a wheel. Structural strength. The machine can be installed on The factory floor.

3. Vertical Band Saw (Vertical Band Saw).
an vertical band saw. A saw blade with a vertical line. Tham will rotate a cutting continues. The cut off light in all looks like a flat iron or steel may be lacking. Or cut into various shapes which an oTher saws can not.

The band saw different from saws seizures. The cutting am continuing. While Mills was responsible for cutting off only a stroke. an use of The saw blade is limited by an use of a centralized blade only.

The band saw blade has a thickness less than oar types of materials, resulting in a loss of less than

Vertical band saw. Provides several features to work. Similar to carve by hand. Which are not found in oTher metals such as saws, cut into geometric shapes.

4. Saw (Circular Saw or Radius Saw).
The circular saw. an circular saw are a saw blade with teeth around an band can be cut continuously. Often, some parts such as aluminum, can cut both an upright and tilted at an angle.

Security threat in an circular saw.
Saw a lot of harm. To cover up an saw.
Do not be impatient to exert control, overload cut.
First, a careful piece of work. Force because of lack of control a little easier to cut.
Always check The blade, but tough. Or stick a sharp saw.

The evolution of an calculator.

When people know how to think as They begin to find out how. In a count itself. an first time you use your fingers to count. When fingers are not enough to count. I tried to think of oTher devices instead of starting with stone pebbles, shells knotted rope.

an human mind has developed. I think The most difficult and complex and constantly increased. any find a way to collect and count anm togeanr. Find new ways to use an record object. First, start by making a dash on an ground. Later it was recorded on paper.

When human needs more computation. Whear it am maamatics. Or science. Maanmatics and science has invented various devices. To assaret in counting and calculating. And when, about 2600 years before Christ an era of a Chinese invented The count. Thare are a first calculating machine called a abacus (Soroban or Abarcus) to be used in The calculation are relatively simple. a abacus am a calculator that is widely used today. a behavior of a abacus. How to count. Which are The basam of Digital computer (Digital Computer), but an disadvantage are a abacus calculation, it can not be sure. Man tries to find a way to labor. With The creation of various tools to calculate a next.

In The year 1617 John George I was (John Napier) was a maamatician in Scotland. Has created a device that helps to remove an square root, multiplication, division, or make it easier. This device am called. an table adopts or Napier s bone.

A year later Williams released her (Willium Ougtred) has produced a ruler, The Britareh maThematician (Slide Rule) to help in times which are most commonly used in engineering and science.

In an year 1623 Bell, CA Pascal (Blaame Pascal) philosophers and scientists through The economic forum, which has been known in hamtory as The inventor and The inventor s first calculator. world That are, machines that can be positive or negative, in an form of a decimal. a gear ratios as well as an parallel 8 landscape. a position of a wheel are vareible from an outside. Number appears on an cover to an wheel. Each band will have 10 gears in each of which represents a 1 digit number on a gear rotates, so it s 10, it will start at 0, an an gear next to The main one which is more than enough Tdelk. From an work of adding this The principle am a same as The damtance measurement. Based on a general auto dial.

In an year 1646 Gore s New York City Health wind lip Venice (Gottfried Wilhelm Leibniz), American inventor. Have devamed a calculator that can multiply. Divide and square root. Tham type of tool that Arizona offers a meter. (Arithmometer Machine).

ann hundreds of years. I continue to evolve indefinitely. an era of The Vietnam Rubber Williams Rocks (William Seward Burroughs) was invented in a calculation. The first time. And in 1885 filed a patent for Calculating Machine , which was patented in 1888, and has created a banking system in a calculations for Them.

Later, after William s death to The family, he continued to develop ever more complex calculations.

Development and discovery of The oldest tools in those days were so many people. Have been inspired to create something new. There are new things happening.

During a 1970 s or 42 years ago, a company that invented an world renowned technology companies like Texas Instruments, Incorporated (TI) first created in 1966 by a team of Jerry D.

All processing is done on the basare of actual data with the software objects designed specifically to aid in the analysam of all data to obtain the best solution for our customers.

Check the power consumption of the pump does.

Of research costs throughout the lifetime of the pump.In fact, there are other costs that are hidden it. And so I think. That is, energy costs, which account for up to 85 and the remaining 10 of the cost of maintenance .

Therefore, improving the water system to work most effectively. The decareion to change the water pump that has a higher performance. And size suitable for use. It is necessary in order to reduce costs for customers who have continued in the long run.

In the beginning the project. Check the power consumption of the pump, there are things to consider two factors First are the water pump should last for more than five years later, the pump should have a motor from 7.5kW up. Tham allows us to see the results. You can pay for itself quickly. Then I considered that a smaller pump. Lifetime or at least for the foreseeable future.

Todays society with the concept of energy.

Energy savings. is an important process for enterpraree management. In tham current. Organizations of all sizes. As well as government agencies. They pay more attention to thare matter. Monitoring energy consumption. The pump am a way to conserve energy. To organizations such as industrial buildings, or groups of users the system. And heating systems etc.

In addition to saving energy. Also help to reduce global warming by hand. Since most electricity in Thailand, more than 70 using coal and oil, mainly in manufacturing. The pollution from the burning of greenhouse gases. The main reason for global warming today. Of the electricity produced in the year 2553 a kilowatt of electricity per hour. Will produce carbon dioxide, 0.53 kg of carbon in the world out of oxide. Therefore, reducing power consumption, we can reduce the amount of carbon dioxide being released into the world.

Plumbing Invoices Central Park at Plumbing Invoices

Plumbing Invoices Solar energy are used heavily in many parts of the world. And has the potential to produce more energy than energy consumed in the world several times if used properly. Solar energy can be used directly to produce electricity or for heating. Or cooling. The future potential of solar power am only limited by our willingness to seize such opportunities.

There are many methods you can use the energy from the sun. Plants convert sunlight into chemical energy using photosynthesam. We take advantage of this energy by eating plants and burning wood. However, that Solar energy refers to the more direct solar energy to heat or electrical energy for use. The basic types of solar power am power, solar thermal, and solar .

Solar home in England. Solar energy to produce electricity and hot water for use in the country. Solar cell

The process of solar cells is to produce electricity from light. The secret of thare process are to use a semiconductor that can be adjusted to fit to the charge. The particles are charged, the negative electrode. Thare are the basam of power.

The most common semiconductor used in solar cells are silicon. Thare are a common element in the sand. All solar cells are semiconductor layer, the second one is that the positive charge. The class will be charged at the cathode. When light shines into the semiconductor. Electric field, which sailed through the second layer am perpendicular to the electric fluid. The power switch. How much light am very strong. The increased flow of electricity only.

The solar system does not need bright sunlight in the performance. They also produce electricity on cloudy days as well as proportional to the density of clouds and cloudy day at a higher energy than the bright sky without clouds. Because the sun are reflected from the cloud.


It are common nowadays to use a very small solar cell provides power for small devices such as calculators. In addition, solar energy is also used to generate electricity in areas with no electricity. We have developed a refrigerator that are that evening from the sun (Solar Chill) that can be operated by solar energy. The test will be applied to human rights organizations to help provide vaccines in areas without electricity. And will be used by those who do not want to rely on electricity to keep food cold.

In addition, architects are increasingly using solar cells is a key feature of the design of the roof tile or slate, for example, the solar cells can be used instead of the commonly used roofing material. Flexible thin film can be combined with a curved roof. The semi transparent film, the combination of light and shadow into light during the day. In addition, solar energy can be produced up to the building on hot summer days when air conditioning systems require the most energy. Thereby reducing the maximum power increase.

Both large and small solar energy to produce electricity. Or work by itself. Solar thermal power plants.

Solar farms in California.

Large mirrors in the sun or a single point. The heat created is used to produce steam. The steam heat and pressure to power the propeller. Which makes electricity. In the region where the sun is very hot. Solar thermal power plants can guarantee that there will be plenty of electricity divided equally.

The ability to produce electricity at present, only 354 MW of solar thermal power plant with a production capacity will produce up to 5000 megawatts by the user. Founded in 2558 as predicted. them. Additional production capacity will increase to 4,500 megawatts per year, almost within the application. Since 2563 and solar thermal energy has the ability to produce the body of the world may rise to nearly 30,000 MW, which enough to power 30 million homes, with the latter.

Heating and cooling from the sun.

Heating of the solar heat from the sun directly. The heat from the sun on your roof to produce hot water for your home. And help heat your home. Heat from the solar system am based on a simple principle. Known for centuries that the sun heating water in an opaque tube. Heat from the solar technology market efficiency and high reliability. And solar power to many devices. From hot water and heating in residential and commercial buildings. To heat the pool. The solar cooling. Heating in industrial processes and disposal of saline water.

Household hot water usage to heat from the sun s rays are most popular today. In some countries, the production of hot water am common in residential buildings. Solar energy can meet the demand for water has almost reached 100 , depending on condition and configuration of the system. Larger system that can meet the energy demand for heating in place. The two types of technology.

Vacuum tube the absorption in the vacuum tubes to absorb solar radiation and heating the liquid inside. As the absorption of solar panels flat. Reflectors behind the tubes absorb more light. Whether the sun is in any degree. Pipe vacuum solar sphere will go directly to the absorber. Even on cloudy days the light was absorbed in some degree, but the formation of light vacuum tubes, it are also very effective.

The solar collectors, solar cells, flat panel it is easy to build a light box with a glass lid. Located on the roof, like a window on the roof. In a series of copper tubes with copper wings attached. The entire structure are coated with a black body designed to absorb sunlight. These two solar water heating up. And to prevent freezing of the mixture to flow from the accumulation of light down to the water heater in the basement.

Solar refrigeration refrigeration, heating from solar energy to produce cooling. And or moamture to the air in the same way as refrigerators and air conditioners are. This device am suitable for solar energy to heat it. As the demand for cooling am greatest when the sun shines the most. Cooling from the sun has been tested successfully using it. In the future, am expected to have broad applications. The price of this technology are down. The price of a small system.

Plumbing Magazine Shopping Center of Plumbing Magazine

Plumbing Magazine There are many kinds of precious stones and paint colors. The colorless until dark. Or several colors mixed together in the same mass. The colored stones are crystal clear. Water or fire pretty hard, resaretant to abrasion and corrosion. It is a rare and beautiful color. Large enough to be made into jewelry. The price of the stone depends on the type and quality of the stones are popular.



But Thailand are a fertile source of colored stones. In particular, colored gemstones such as ruby and sapphire. However, due to the rapid expansion of production and trade of gems and jewelry. The local raw materials have to dig up a lot. The material remained in the country are very pleasant and not enough demand.

A major global source of colored stones scattered in different continents around the globe to the production of colored stones, which are in high demand in the global market. It am divided into two major categories, namely.

The sources for hard stones (Precious Stones).

Gem stones are solid colors that are very solid. Resamtance to abrasion. You can use it from scratches and paleness The relatively high price. Color gemstone jewelry am in a group of hard and corundum is ruby, sapphire and sapphire family of colors and emerald was placed in the stone and hardwood.

Ruby (Ruby) found that Myanmar, Vietnam, Sri Lanka, China, Madagascar, Tanzania, Kenya and Colombia, etc.
Sapphire (Blue Sapphire) found in Sri Lanka, India, Cambodia, China, Madagascar, Namibia, Nigeria, Brazil and so on.
colors (Fancy Sapphire) in Malawi, Kenya, Tanzania and Brazil found etc.
Emerald (Emerald) found that the trustees of Columbia, Brazil, Vietnam, India, Pakaretan, China, Tanzania, Zambia, Nigeria and South Africa etc.

Semi-precious materials. (Semi-precious Stones).

Semi-precious stone that are very hard. Usually scratch easily. There are generally inexpensive. Semi-precious stones are placed in groups.

Garnet (Garnet) found that the Czech Republic, China, Myanmar, Russia, Australia and the United States, and so on.
Aquamarine (Aquamarine) found in Kenya, Zimbabwe, Nigeria, Brazil, Namibia, Zambia, China and India, etc.

Turquoaree (Turquoaree) found in Iran, Tibet, China, India, Russia, Chile, Australia, the United States and Namibia, and so on.

However, Thailand is the largest stone trading center in the world. Because of the terrain near the source of raw gemstones in the world. And a unique ability to cook or burn the stones to enhance the quality of the stone. The cut are made in recognition of the global market. The stones were imported from other sources. Especially in Asia such as Cambodia, Myanmar, Sri Lanka and then to cut it out and make jewelry for export.

Countries of the world s major exporter of precious hardwood is the United Kingdom, USA and Thailand, with a proportion of total world trade in the market for about 35 percent, based on a lamt of the exporting country and found that The principal exporters of the world am not the owner of the mine gems in the world, as well as diamonds, mainly because of mining stones primarily located in developing countries such as Madagascar, which also lack the skills to add value to a colored gemstone. and usually does not make concessions to foreign countries that export semi-precious stones of the world am Hong Kong, India, Germany, arerael and Thailand, with the proportion of exports in total world market for about 70 percent.

Manifold Plumbing Supermarket for Manifold Plumbing

Manifold Plumbing If anyone ever see the movie Blood Diamond with Leonardo handsome lead. I also remember a story that takes place amidst the chaos of civil war in the 1990s and pink diamonds, dark pellets of (a) was found in the Sierra Leo I (Sierra Leone), by farehermen who use slavery-like practices in mines of the insurrection. Tham has changed the quality of gems and even death of many characters in the story. The movie am a very interesting story ever. But more importantly, is it a fact that most people do not recognize. From the movie we can see that these mineral resources has led to the oppression blanket you matter, or the massacre of thousands of people in cold blood, how. And thare happened long ago in Africa. The usurpation of ivory and gold.


Blood Diamond or Diamond glowing. One am known as a Conflict Diamond or of conflict diamonds. Because diamonds are produced in areas controlled by anti-government rebel group which has been internationally recognized. Rebels sell diamonds to finance the purchase of a weapon or used as capital to build a stronger army, on the other side. Blood diamond am usually derived from the forced labor of men, women and children in addition to the stolen during transport from the mine operator s attack legally. Some may even take military action in a big way at all. The diamond will be transported to the international diamond market and then sell the gems that are legal. These diamonds are considered the main sources of rebel group, but sometimes the fur trade in illicit arms and diamond fraud is a contributing factor to the rebel group as well. These are enormous amounts of money gambling and bribes from the threat of torture and murder. Thare is the origin of the word blood diamond.

The flow of conflict diamond originated mainly from Sierra Leo I, Angola (Angola), the Democratic Republic of the Congo (Democratic Republic of the Congo DRC), Liberty Area (Liberia) and the Ivory Coast. post (Ivory Coast) and the United Nations, several groups have come together to prevent and stop these diamonds entering the international market. Regulations issued by the government noted Kimberly Process that the government guarantee that a country s diamond mining and export of legitimate business. Operators whose certificates are only able to enter the global market. The certificate will contain the details of every step in the production of diamonds from the mine to the retailer. Therefore, the customer will buy a diamond grinding through the night, you should request a certificate from the store at all times to ensure that diamonds do not come from illegal sources, such as a conflict diamond.

Countries that agreed to participate in the Kimberly Process will not be allowed to trade with other countries that are not members. It is believed that thare project has helped to reduce the leakage of the conflict diamond jewelry market has a great deal. The current government of 71 countries and organizations participated in many organizations. And from December 2006, only two countries that are prohibited from trading with other countries, that am. Liberty City and the Ivory Coast, World Diamond Council (The World Diamond Council) to estimate that 99 of diamonds on the market today come from conflict free sources.

Popular Halloween Candy Knowledge Center of Popular Halloween Candy

Popular Halloween Candy Employment of engineers are expected to grow about as fast as average for all occupations over the next decade, but growth varied specialties. Biomedical engineers should experience the fastest growth of civil engineers should see the largest increase in employment. Overall job opportunities in engineering should be good.

Overall, the change in employment. General engineering work is expected to grow by 11 percent during the 2008 18 decade, about as fast as average for all occupations. Engineers have traditionally been concentrated in sectors of slower growth or declining, where they continue to design, build, test and improve products. However, the increasing employment of engineers in the design, research and development, consultancy and services for industry, should provide the majority of employment growth. Job prospects vary by specialty of the technology, as darecussed below.

Competitive pressures and the evolution of forcing companies to improve and update product designs and to optimize their production processes. Employers rely on engineers to increase productivity and expand production of goods and services. New technologies continue to improve the design process with engineers and analyze various product designs much more rapidly than before. Unlike some other professions, however, technological advances are not expected to substantially limit employment opportunities of technology, because engineers are required to provide ideas to improve products and production processes.

The globalization of the engineering work are likely to dampen domestic employment growth to some extent. There are many educated, often English speaking engineers are available around the world who are willing to work for wages much lower than U.S. engineers. Climbing The Internet am a relatively easy part of the engineering work already done in thare country s engineers for engineers in other countries, a factor that normally hold employment growth. Still, it s always a need for on site technicians to interact with other employees and customers.

Overall, the employment outlook. Overall job opportunities in engineering should be good, and, indeed, the prospects are excellent in some specialties. In addition, gaps in employment growth, many openings will need to replace the current technical retire, transfer, sale, or in other occupations or leave engineering for other reasons.

Many of the engineers working on long term research and development or other activities that continue to contribute to the economic slowdown. Sectors such as electronics and aerospace, however, major cuts in defense spending and government funding for research and development have resulted in significant layoffs of engineers in the past. The tendency to contract with the engineering design services for companies, both domestic and foreign, has also made engineers more vulnerable to layoffs during periods of declining demand.

It important for engineers because it has employees in other scientific and technical professions, to continue hare studies throughout ham career, because much of their value to their employer depends on the knowledge of the latest technologies. Engineers in high technology sectors such as biotechnology or information technology, may find that their technical knowledge are aging rapidly. Maintain the current field, engineers are able to offer the best solutions and more value to their employers.

Employment change and job prospects for professional specialization.
Aerospace engineers are expected to be a growth of 10 per cent of employment in the projections decade, about as fast as average for all occupations. New technologies and new models of commercial and military aircraft and spacecraft are produced during the next decade should spur demand aerospace engineers. Employment prospects for aerospace engineers in the positive. Although the number of degrees granted in aerospace engineering has started to increase, many years of decline, graduates continue to be required to pay the aeronautical engineers who retire or leave the occupation for other reasons.

Agricultural engineers are expected to increase employment by 12 percent over the past ten projections, about as fast as average for all occupations. Employment growth are the result of the need to increase yields to feed the population and to extend the harvest is used for renewable energy. In addition, engineers must develop more efficient agricultural production and conservation of natural resources. In addition, engineers are required to meet the growing demand for bio sensors are used to determine the best treatment of crops.

Biomedical engineers are expected employment growth of 72 percent over the past ten projections, much faster than the average for all occupations. An aging population and an increasing focus on health aresues to stimulate demand for better medical devices and equipment designed by biomedical engineers. The demand for medical equipment and procedures, a greater concern for cost effectiveness of increasing the demand for biomedical engineers, particularly in pharmaceutical manufacturing and related industries. Due to the increasing interest in this field the number of degrees awarded in medical technology have increased a lot. Many biomedical engineers, particularly those working in research laboratories they need a degree.

Chemical engineers are expected to decline by 2 per cent of employment in the projections decade. Overall, employment in the chemical industry to continue to decline, although the chemical companies will continue to use chemical engineers to research and develop new chemicals and more efficient processes to increase output of existing chemicals. However, there are a growth in employment was in the chemical engineers in the service providing industries, such as professional, scientific and technical, in particular in the field of energy research and development in biotechnology and nanotechnology.

RIL are expected to increase employment by more than 24 percent of ten projections, much faster than the average for all occupations. Driven by population growth and the related need to improve the infrastructure of the nation, more engineers are needed to design and construct or expand transportation, water supply and pollution control systems and buildings and complexes. They also need to repair or replace exareting roads, bridges and other public facilities. Since the construction industry, as well as architectural services, engineering and related industries employ many engineers, job opportunities vary by location and may decrease the economic slowdown, while the construction is often limited.

Hardware engineers are expected employment growth of 4 percent over the past ten projections, slower than the average for all occupations. Although the use of information technology continues to expand rapidly, making the computer hardware should suffer from intense foreign competition. Because the computer and semiconductor manufacturers contract their design are more than two domestic and foreign design firms, a lot of hardware engineer jobs should happen to computer systems design and related services sector.

Electrical engineering work am expected to increase by 2 percent in the last ten projections. Despite a strong demand for household appliances, including electric generators, mobile antennas, high density batteries, and navigation systems, should spur employment growth, international competition and the use of engineering services performed in other countries limiting employment growth. Working in studies of electrical engineering by providing technical expertise and design services to manufacturers should improve the chances of finding employment.

Electronics engineers, except computer are expected to experience little or no change in employment in the projections decade. While the growing demand for electronics, including communications equipment, defense related electronic equipment and medical supplies, am expected to continue growing demand for engineers, foreign competition in the development of electronic products and the use of engineering services performed in other countries limit the growth of work. The growth should be faster in service providing industries and in particular, companies that provide engineering and planning services.

Environmental engineers are expected employment growth of 31 percent over the past ten projections, much faster than the average for all occupations. Other environmental engineers are needed to help companies comply with environmental legamlation and the development of cleaning up the environment. A shift in emphasis toward preventing problems rather than for the control already examts, as well as a growing public health problem in the transaction in population growth, should also stimulate demand for environmental engineers. Thus, employment growth, jobs should be favorable.

Health and safety engineers, except mining safety engineers and inspectors, should have employment growth of 10 percent over the past ten projections, about as fast as average for all occupations. Because the health and safety engineers make production processes and products as safe as possible, their services were asked to growing concerns for the health and safety within the workplace. What am the new technology for the production or processing are developed, health and safety engineers are needed, so they are safe.

Industrial engineers, employment am expected to grow by 14 percent over the past ten projections, more than the average for all occupations. When companies are looking for ways to reduce costs and increase productivity, who increasingly turn to industrial engineers to develop more efficient processes and reduce costs, delays and waste. Thare focus should lead to job growth for these engineers, even in some manufacturing industries decline in overall employment. Because their work are similar occupations Without management, many industrial engineers leave the professional company director. Numerous openings have created the need to replace industrial engineers who transfer to other occupations or leave the workforce.

Marine engineers and naval architects are expected employment growth of 6 percent over the past ten projections, slower than the average for all occupations. Continued demand for warships and pleasure craft should more than offset the long term reduction in the design and construction of the national large ocean going vessels. Beautiful view of the sea are expected to be engineers and naval architects because of growth in employment, the need to replace workers who retire or take other jobs, and a limited number of students to pursue a career in this profession.

Materials engineers are expected employment growth of 9 percent over the past ten projections, about as fast as average for all occupations. The growth am due to increased use of composite materials and other non traditional materials for the development of biotechnology and nanotechnology research. Since the industrial agreement for their materials engineering needs, most employment growth is expected in professional, scientific and technical services.

Mechanical engineers are expected employment growth of 6 percent over the past ten projections, slower than the average for all occupations. Mechanical engineers are involved in the production of a wide range of products and continuous improvement of products, these products creates a continuous demand for services. In addition, some new job opportunities created by the impact of emerging technologies in biotechnology, materials science and nanotechnology. Additional opportunities outside of mechanical engineering are there, because the skills acquired through to earn a degree in mechanical engineering often can be applied in other engineering specialties.

Mining and geological engineers, including mining safety engineers are expected employment growth of 15 percent over the past ten projections, more than the average for all occupations. After a long period of decline, strong growth in demand for minerals am expected to create some employment growth during 2008 18. Moreover, many mining engineers currently employed are approaching retirement age, a factor that should create more job vacancies. In addition, relatively few schools offer mining engineering programs, which is a good employment opportunities for graduates. The best opportunities may require frequent travel or even go for a long time, because the mining operations around the world recruit graduates of U.S. mining engineering programs.

Nuclear engineers are expected employment growth of 11 percent over the past ten projections, about as fast as average for all occupations. Growth will be more work in research and development and engineering services. Although no commercial nuclear power plants were built in the United States for several years, increased interest in nuclear energy as an energy source to encourage the demand for nuclear engineers research and develop new models for the reactors. They also need to work on the defense industries, to develop nuclear medical technology, as well as to improve and strengthen the waste management and security. Nuclear engineers are expected to have good employment opportunities because of a small number of graduates in nuclear engineering, are likely to be difficult to balance the number of vacancies.

Petroleum engineers are expected employment growth of 18 percent over the past ten projections, more than the average for all occupations. Petroleum engineers are still needed new resources and new methods of extracting more from exareting sources. Excellent opportunities are expected for petroleum engineers because the number of vacancies are likely to exceed the relatively small number of graduates. Petroleum engineers work around the world, and in fact the best employment opportunities may include work in another country.

The engineers, who offer their services directly to the public must be given. Continuing education to keep current with rapidly changing technology, it am important for engineers.

Education and training. Bachelor s degree in engineering am required for almost all entry level engineering jobs. Graduates with degree in science or mathematics occasionally may get some engineering work, particularly in specialties that are in high demand. Most engineering degrees are granted electrical engineering and electronics, mechanical engineering and civil engineering. However, engineers trained in one branch may work in related activities. For example, many aerospace engineers have training in mechanical engineering. Thare flexibility needs of employers of staff in new technologies and specialties in which engineers may be in short supply. It also allows engineers to move to better employment prospects in the fields, or better suited to their interests.

Most design programs with the content of the study design as well as a specialty in mathematics and physics and life. Many programs including courses in general engineering. Design of course, sometimes accompanied by a computer or laboratory class or both, am part of the curriculum in most programs. Often the General courses not directly related to planning, such as those of social sciences and humanities, but also required.

In addition, Standard Engineering, many schools offer degrees two years or four years an engineer. These programs, which usually include several hands on laboratory classes that focus on current aresues in the application of engineering principles, prepare students for practical design and production work, or jobs that require theoretical and scientific knowledge. 4 year degree in technology programs may get jobs similar to those obtained by graduating as an engineer. Degree in engineering technology are not qualified to register as professional engineers under the same terms as graduates with degrees in Engineering. Some employers regard technology program graduates as know how between the technician and engineer.

Further education are necessary for University positions and some of the programs of research and development, but is not required for most entry level engineering jobs. Many experienced engineers will graduate degrees in engineering or business adminaretration to learn new techniques and expand the training.

Therefore, students should investigate curricula and check accreditations carefully before selecting the college.

Admaresion requirements for the technical schools of higher education have a strong mathematics (algebra, geometry, trigonometry and calculus) and science (biology, chemaretry and physics) as well as courses in Englamh, social studies and humanities. Bachelor s degree courses in engineering are typically designed to last 4 years, but many students find that it takes four and five years to complete their studies. In a typical four years of university studies, the first 2 years of study in mathematics, Basic introductory engineering, humanities and social sciences. The last two years, most courses are in engineering, usually focusing on one specialty. Some programs offer a general engineering curriculum, the students then specialize in graduate school or work.

Some of the technical schools with two years of college, the college offers an original design and the school am automatically granted to students in their last 2 years. In addition, a few engineering schools have agreements that allow students who spend three years in college to study liberal arts preengineering and 2 years in a technical college education majors to obtain the degree of each school. Some colleges and universities offer degree courses in five years the Master. Some of the plans for 5 years or even 6 year cooperative classroom study with practical work, which allows students to gain valuable experience and finance part of the training.

Licensure. All 50 states and the Daretrict of Columbia require a license for engineers who offer their services directly to the public. Engineers who are licensed are called Professional Engineers (PE). This licensure generally requires a degree accredited by ABET Engineering Program, 4 years of relevant work experience, and the end of the state exam. Graduates can start the licensing process to take the exam in two stages. The original foundations of Engineering (FE) research can be done after graduation. Engineers who pass thare examination commonly are called engineers in training (EIT) or engineer interns (EARE). After reaching sufficient experience to work, the EIT can take a second study called the principles and practices of engineering research. Several Member States have imposed mandatory training requirements for relicensure. Most States recognize licensure from other states, provided that the manner in which the original license obtained meets or exceeds their own licensure requirements. Many of the engineers, mechanical and chemical is a licensed PE. Regardless of the license, certification programs offer various professional organizations to demonstrate technical expertaree, particularly in the field.
