Engineering is the term given to describe a profession in which mathematics and sciences are applied to the efficient use of materials and forces present in nature. It is used for solving practical problems encountered in diverse fields. Based primarily on mathematical calculations for design and manufacture, this field also takes into account various scientific factors related to practicability and safety.
ABOUT CHEMICAL ENGINEER
There are several branches and sub-branches of engineering. Some of the most important ones are civil engineering, mechanical engineering, electrical engineering and chemical engineering.
Chemical processes refer to those processes in nature that result in chemical changes being effected in the reacting components. Such processes are usually irreversible. They form the basis of experiments carried out in a number of fields such as biochemistry and pathology. Samples of particular substances can be analyzed and general conclusions can be drawn about the nature of the substances. Chemical processes are particularly important in the diagnosis of diseases in humans and animals.
Apart from the above, chemical processes, as occurring naturally in living beings, form the core of metabolism and thus help sustain life.
ABOUT COMPUTING AND INTERNET ENGINEER
The Internet is a system of connected computers. By using an Internet Protocol a user can access it and browse through the World Wide Web. Millions of web pages appear each day and the number of Internet users is constantly rising. The main use of it stands in information gathering and swapping. Basically people will go through websites so that they can find what they want to know. Several databases are available in the form of search engines like Google or Yahoo.
EXPLANATION
If you are using the OS X version of Microsoft's Internet Explorer, you might have come along an annoying bug. While PNG images are correctly rendered inside a web page, when trying to view it outside the page (opening it from your own computer or from a remote location, but outside a web page), it will not show at all.
The origin of this problem is, ironically enough, the Apple Quicktime plugin, which overrides Internet Explorer's settings. However, the problem is easy to solve.
STEPS
1. Open the System Preferences panel. In the Internet & Network section, open the Quick Time panel.
2. In the Advanced section, click MIME Settings. This will open a new window. In this new window, click the arrow near Images to expand that section. Find a checkbox labeled "PNG image file" and make sure it is not checked.
3. Launch Internet Explorer and go to Preferences, File Helpers.
4. There are two parts referring to PNG. One is "PNG Image [image/x-png]", and the other one is "Portable Network Graphics [image/png]"). Select each one of them and click Change, which will pop up a new dialog. Go to Handling, and change it to "View with browser". Click OK.
5. Restart Internet Explorer.
NOTES
Although, knowing Microsoft's history of buggy products, you may be tempted to say this is yet another one, the truth is that truly responsible for this is Quicktime. Nevertheless, if you do not have any strong reason to use Internet Explorer (i.e. if you can use something else), you should try some other browsers as well. Safari seems like the obvious alternative, being probably as user-friendly as Internet Explorer, but others, like Opera, Firefox or Omniweb may also be a good alternative. You should at least try them.
