Overview of Plastic Surgery

– Plastic surgery is a corrective specialty that is used for personal or medical purposes. Many people think about plastic surgery is just used for making your nose smaller or breasts bigger, when actually it is used for much more. For example, plastic surgery can also help someone who has gotten burned, by placing skin from another part of the body to the burn. Plastic surgery is primarily used for fixing themselves because they feel self-conscious or feel uncomfortable in their own skin….  

Type of Burns and Treatment

– Burns are injuries to the tissue caused by an encounter with heat greater than one hundred twenty degrees Fahrenheit, friction, electricity, chemicals, or radiation. There are many signs to let a person know if he or she may be burned; some of the signs include: redness, swelling, and pain upon the skin. When a person is burned, he or she may see the skin peel, appear white or charred, and feel numbness on the burned area. In fact, severe burns may cause weakness, faintness, pale and unpleasantly sticky skin, rapid pulsating and breathing, and bluish lips and fingernails….  

Negative Effect Plastic has on the Environment

– In 1862, Alexander Parkes unveiled an invention, a compound known as celluloid that would change modern history. This is the first known plastic compound to demonstrate the ability to mold when heated and maintain its shape once cooled. While the chemical compounds have evolved over the years, so have its uses and our dependency on them. If we look around our room today, we can see that nearly every product in our house either consists or was built by some form of plastic. This dependence raises some alarming questions….  

Investigating Plastic Degradation due to Sunlight

– All plastic types fall under a code no, known as an SPI code (as devised by The Society of the Plastics Industry), based on their chemical composition. As some plastics are more easy to recycle than others. Polyethylene Terephthalate ( PETE or PET) it is the most commonly recycled plastic. High-Density Polyethylene, or HDPE. HDPE products are very safe and they are not known to transmit any chemicals into foods or drinks. Plastic labeled with an SPI code of 3 is made with Polyvinyl Chloride, or PVC….  

The Development of Heavy Equipment

– Imagine a world where the only earthmoving is what can shovel, and everything was pulled by draft animals. Up until 1850, when the steam traction was popularized, man power, draft animals, and a few simple machines was how earth was moved. Without the ability to change the contour of the land, structures had to be built in areas where the land had the proper contour. The need to move more earth more efficiently and change the lay of the land would grow as time went on. The power of steam has long been know….
