5649.46 | PP | 3436.41 | 8.1 Out of the four plastic materials‚ High Impact Polystyrene (HIPS) exhibits the highest impact strength compared with the other three. This suggests that HIPS withstand impact strength best‚ followed by High density polyethylene (HDPE)‚ General Purpose polystyrene (GPPS) and Polypropylene (PP) in descending order. The reason why HIPS has a higher impact strength than HDPE is because HIPS is made of a larger monomer‚ styrene (C8H8 or C6H5CH=CH2) while HDPE is made of

The Effects of Plastic Bags on Environmentt * | * The effects of plastic bags on the environment are really quite devastating. While there are many objections to the banning of plastic bags based solely on their convenience‚ the damage to the environment needs to be controlled. * There is no way to strictly limit the effects of plastic bags on the environment because there is no disposal method that will really help eliminate the problem. While reusing them is the first step‚ most people

Industrial Uses of Ethene Ethene has two main industrial uses. Ethene is used to accelerate the ripening of fruits and is most commonly used on bananas and also on citrus fruits. The other use of ethene is in the manufacture of plastics‚ such as packing films‚ wire coatings‚ and squeeze bottles. Fruit: Ethene is made from the process of cracking hydrocarbons from petroleum. Ethene can then be used to make other raw materials like‚ ethanal‚ ethanol‚ and ethyl chloride. Ethene also occurs naturally

l method For the proposed analytical method we used SPSS Student Version 17.0 for Windows. This program helped us to rearrange and organize the data we gathered from the survey. Furthermore it allowed us to analyze and interpret the data into expressive information. With the aid of SPSS we find scale data such as frequencies‚ mode‚ median‚ range‚ variance and standard deviation. In addition cross tabulations‚ descriptive analysis techniques and inferential analysis techniques 4.0 RESEARCH

New employees have a very difficult time figuring out the steps of processing a patient. Although‚ you take notes it seems to be confusing trying to figure out how to organize the steps in the proper order. Everyone does it differently; therefore‚ there is not a per-say right way to process a patient. First‚ the patient arrives at the office and signs in on our sign-in sheet. The registration staff scans in their insurance and driver’s license photo. Registration obtains and enters the patient’s
