Building a web site is a vital step in expanding a business beyond the local level, but if the site is not attractive and easy to find and use, it can do more harm than good. It is possible for amateurs to build a simple functional web site, but a business with such a site suffers in comparison to competitors who have a more elaborate web presence. For professional web development Sydney businesses should seek out an established web design company.

Planning a web site

Professional web designers do not begin by deciding what content should go on a web site. They start out by deciding what problem the site is meant to solve.

• Raise awareness of the company in its target market


• Enhance the firm’s reputation as a leader in its field


• Provide customer service


• Generate sales leads


• Make sales directly

Only then do the best web design artists begin to generate a plan for the new site. Web professionals will choose the most appropriate technologies and the best software for the purpose. Marketing strategists will weigh in as timing is discussed and personnel development specialists will create programs for training and ongoing support. The plan will be presented to the client along with a statement of the cost.

Implementation

Once the plan is approved, content is collected and the actual coding begins. In most cases a basis of HTML code will be enhanced with CSS stylesheets to define the site’s appearance and interactivity achieved with javascript, php, or cgi scripts written in perl or some other language. Databases and content management systems may be required for some applications. In all cases, search engine optimization will be considered when writing web copy to help the web design achieve a good ranking and draw in visitors.

Upon completion of web development Sydney designers begin a process of testing. This will involve viewing the site using multiple browsers and versions and allowing at least a few naive users to attempt simple operations. At this point the client often has another chance to approve the site.

Going Live

After approval, the site is placed on the Internet for the world to see. There are three main possibilities for hosting:

• The client may own and operate the servers where the site is hosted


• The design company may host the site on its own servers


• A third party may own the servers and contract to provide hosting

The host should be selected in advance, since servers running Microsoft system software may use certain proprietary technologies not compatible with other operating systems. Once all the code has been written, tested and approved, it is uploaded to the servers and tested once again.

Statistical analysis

Before computers were ever invented, marketers knew the importance of measuring the success of their efforts. Then as now, this involved determining the exact return generated by each dollar invested in advertising, in this case in a web site. Web designers will either provide means for the client to monitor the statistics or contract to do it themselves. Once the numbers are in, the client’s managers can use the data to make decisions about tweaking the site for maximum performance.

Even after the development and implementation are complete and the design has been finalized, further design work is still desirable. Changes in competition or the customer base, developments in the economy at large or new products and services all call for design work on the web site. New web technologies may have great potential for a particular application. A good web design company will provide continuing support as long as a web site is up.

Web development is a complicated process. A good professional designer can be an invaluable asset in achieving the exact sort of web development Sydney clients need. The benefit of a well-designed web site can give a firm a leg up on the competition obtainable in no other way.

Directional drilling, also known as slant drilling, has revolutionized the search for resources around the world. Formerly restricted to vertical drilling, many people in various industries were concerned about the limits of the non-renewable resources on the planet. The development of three new techniques for reaching oil, gas and other underground substances allowed drillers to not only extend the lifetime of the Earth’s resources, it also made it safer to work in drilling.

A Brief History of Directional Drilling

The invention of slant drilling was really accidental. Lawsuits in the 1920’s established that many so-called vertical drills were really slanting to such an extent that they crosses property lines on the surface. Thus drillers realized that it was feasible to drill on at least a minimal slant.

The next issue addressed within the industry was accuracy. Now that it was established that drills could safely dig on a slant, the question remained as to whether they could be aimed in a particular direction. The development of gyroscopic compasses allowed work to continue in nearly any direction desired.

Advances in telemetry allowed drill bits to actually communicate vital directional data back to drillers on the surface in real time. Another crucial step in advancing this technology came when downhill drilling was developed. This technique took advantage of the hydraulic power of the mud that surrounded the drill deep down inside the Earth. This actually permitted drillers to turn the bit at the end of the drill without having to remove the drill shaft. In fact, the drill could stay in place while the embedded bit rotated as needed.

Advantages and Disadvantages

One foreseen and welcome advantage of this technology was the ability to avoid hard obstructions between the surface and the target of an oil or gas drill. This cut down on equipment and labour costs. Besides that, it made many reserves candidates for drilling that were previously thought impossible to access.

People who are outside the drilling industry do not consider how important directional drilling was for safety. Even reserves that could be reached by vertical drilling were sometimes off limits because pressures were too great. When fires broke out, pressures drove the gas and oil out too quickly for fire-fighters to bring them under control. Directional drilling allowed distant relief wells to be dug in order to relieve the pressure and control accidental fires.

Initially, though directional drilling was costly due to the amount of time it took to drill on a significant slant. This delay was eventually resolved, but operating costs are still high. One simple reason for this is that vertical drills can rely on gravity more than slant drills can.

Three Kinds of Slant Drilling

• Oilfield directional drilling is focused on reaching new oil reserves or on exploiting reserves that were once thought depleted as far as vertical drilling was concerned


• Directional boring is actually used to install pipes underground without digging trenches and revealing the soil below. This is particularly helpful with very deep pipes which would require the removal of considerable layers of the upper soil


• In-seam directional drilling is used to access the methane in a coal-bed

Electromyography is used in the diagnosis and treatment of dozens of illnesses, from carpal tunnel syndrome to muscular dystrophy. Generally, an EMG may be requested by a doctor to aid in diagnosing patients who report muscle weakness, pain, or tremors, though other symptoms may prompt the use of the test. In many cases, electromyography is used in conjunction with nerve conduction testing.

EMG tests measure the electrical activity in muscle and nerve fibers. When muscles contract, a small amount of electricity is produced. Electrodes are used to detect this electrical activity, and the results are then used to determine the extent and type of muscle or nerve damage patients may be suffering from.

EMG Needle

Depending on the nature of the complaint, either intramuscular or surface EMG tests may be used. Intramuscular EMG tests involve the use of a thin needle attached to an electrode, which is inserted into the muscle. Surface EMG tests use electrodes on the skin above the muscle. While both tests are safe, intramuscular testing may cause some soreness and discomfort for a few days afterwards, and carries a very slight risk of infection at the insertion site.

Before the test, the patient will be asked about their current medical condition, whether or not they have a pacemaker or other device that may be affected by the test, and what medications they are currently taking. Patients who are taking herbal supplements or who consume large amounts of caffeine should inform their doctor before the test. In some people, caffeine and certain herbs may cause involuntary muscle movements and tremors, which can negatively affect the test results. Patients will also be asked if they are cold for the same reason.

EMG Test

During the test, the patient will be led through a short series of movements. If nerve conduction testing is done at the same time, patients may experience a mild tingling at the electrode sites. Testing usually takes between thirty minutes to an hour to complete. Electrodes may be left in place or moved several times during the test.

While most commonly used as a diagnostic tool, electromyography may also be used for other purposes. Surface EMG testing may be combined with biofeedback training to help patients learn to manage pain, control anxiety, and combat migraines. It may also be used during physical therapy for stroke patients and those with other forms of nerve damage. EMG controlled prosthetics have already been developed for amputees, and further research is being conducted to develop more articulate, streamlined designs at an affordable cost.

Other uses of electromyography include labor monitoring, the treatment of incontinence due to weakened pelvic floor muscles, and the treatment of sports related injuries. Video game developers are experimenting with EMG controlled game systems, and several toy companies are exploring the possibilities of EMG controlled toys. Because electromyography can detect electrical activity in muscles too weak to produce movement, EMG technology opens a wide range of exciting possibilities for paralyzed individuals, as well as those with neuromuscular disorders that affect voluntary movement.
