CHEMISTRY APPLIED TO "THE ENGINE DISCIPLINE"

Process engineers design, construct and operate plants

“The technology in chemistry towards the big industries”

Almost all the products we use every day are the result of the development of a very prominent discipline called Chemical Engineering. Professionals engaged in this career are known as chemical engineers.

The main reason for exists this discipline is because human beings need to get new materials and products that meet their needs. The current chemical industry moves quickly and progress is steady. However, none of this would be possible today without the great contribution made by Professor Davis of MIT (Massachusetts Institute of Technology). Davis was the first to introduce the concept of "chemical engineering" based on the role of an engineer, as the engine was operating an entire system.

In this case, the system would be an industrial plant, which will apply all the knowledge in chemistry, physics, mathematics, biology, environment and engineering, to generate innovative products from raw materials. This means that whenever we talk about chemical industry, we are talking about the most important workers are there: the chemical engineers. It is also important to note that a process executing a chemical engineer must contain certain stages called "Unit Operations".

On the other hand, this career is associated with other disciplines, mainly with other engineering and science. We can find a chemical engineer at a food factory, in a vehicle oil industry, a cleaning products company, in aircraft spare parts, at an university (like professor), research projects, and even CERN (European Organization for Nuclear Research), where experiments with antimatter and the LHC (Large Hadron Collider) to learn more about the origin of the universe.

All this indicates that this discipline is very complete and very important for the development of mankind in many ways. The modern world needs a lot of chemical engineers and fortunately, Colombia is growing as a country on the issue of products that reduce costs, high quality and do not affect the environment, such as biofuels.

GOOD TOPICS OF ELECTRONIC ENGINEERING

Common electronic components

“Electronic means from the electrons”

The Electronic Engineering mix the knowledge of the basic aplication of electronic with the capacity of an engineer to benefit others; the principal póint is the use of the electron flow to make a managing of information, storage, receipt and give a objective to the data. The principal objective of the aplications of electronic is make easier the lifestyle of the people; making useful the low quantity of voltage required to work, have a great area of function, some of these include the telecomunications, the informatics and the automatization.

The beginning of the electronic engineering has the contribution of the investigation of some physicist like Coulomb, Ampere, Gauss, Faraday, Henry and Maxwell. The theoric frame in the electromagnetism formuled by Maxwell (1865), gave a start point to the comprobations made by Hertz with the generation of an electromagnetic wave (1888), and the later transmission and detection of it made by Marconi in 1896. The Lorentz postulation of the existence of a charged particle named electron in 1895, marked the birth of the electronic.

In the telecomunications, the manufacture of all type of dispositives with easy access to the information webs like television, phone, radio, includes the construction of satellites and other things of the same type. The hardware design is amother aplication and work sector for the electronic engineer, the elaboration of the equipment like computers, the comunication system between it, the design of the microprocessor and integrated circuits; its importance is founded by the neccesity of stay the world comunicated in a fast and economic way.

Another use of the manipulation of the information in electronic, is the optimization of manufacture process, allowing the fast advance and maintenance of a great group of political, economical and social system, saving money and materials, improving the precision of all type of products and devices. The last aplication of electronic is the design of circuits with application in other investigation areas like the medicine, the entertainment, data storage with optoelectronic knowledge and artificial intelligence.
