Plastic Overtaking the Oceans In a study conducted by UC Santa Barbara’s National Center for Ecological Analysis and Synthesis (NCEAS), they found that “8 million metric tons of plastic” are added to the oceans pollution each year. Recently, plastic pollution has been become a predominant problem in the environmental society; however plastic production and pollution has been on the rise since the nineties. Plastic is overwhelming the world, because it is not biodegradable, meaning it can…

Instead, it is a portable and retractable device you can bring with you in your outdoor trips. The best carports for this generation are the ones made of metal, usually of aluminum or steel. There are also that has core panels made of insulated polystyrene foam. This is also wrapped with steel or aluminum. Most metal carports are very durable and affordable. But these kinds of carport are less attractive compared to the aluminum. The aluminum carports has simulate wood look and feel. The time…

The purpose of the experiment was to form ketones by electrophilic aromatic substitution through a Friedel-Crafts acylation reaction of an aromatic compound. In the synthesized Friedel-Craft acylation reaction mechanism, the double bond on the nucleophile anisole (methoxybenzene) attacks the acetyl electrophile. The acetyl compound is then bound to the anisole in the para position, which created the product p-methoxyacetophenone. Since anisole is an activator (electron donor), the acetyl could…

because when the film released there were still people alive that had seen Gandhi, and she should not be able to see the difference. The makeup artists also did a lot of work on Ben to make him look like Gandhi. They put thin cylinder shape piece of polystyrene behind Ben’s ears to make the ears stick out more. Another piece of rubber went inside the bottom lip to make that look fuller as well. Ben’s costume changed according to the setting in the film. In the beginning of the film Ben’s costume…

Building my own RC polystyrene hovercraft from scratch made me realise the challenges and difficulties one might face as an engineer. For instance, producing lift was a major problem, so I made many variations of propellers to find the most effective one. To me, the most enjoyable part of the project was overcoming the obstacles. I was proud and satisfied to see it work after weeks of tests and improvements. As a fan of remote controlled cars for many years, the idea of being an engineer…

Energy performance of the original house is not terribly bad but not satisfied, either. It wastes a huge amount of energy in cooling the living area. Strategies of achieving better passive heating and cooling will be illustrated as following. Reducing cooling energy consumption will be emphasized in designing the new house. The original orientation (315 degrees with living room faces south-west) resulted in excessive heat gain during summer, especially in the afternoon, and insufficient heat…

There is an art work that I want to have a critical analysis is Giant No. 3. The author of this art work is Zhang Huan. This work of art is a colossal figurative sculpture which created in 2008. Giant No. 3 is made of steel, cowskin, wood and polystyrene foam. The color is almost brown and somewhere shows white.

Blow out II Going to the art gallery Blowout was my first time going to an art gallery in a very long time. I have never really been around art. The only art I have been exposed to has been through art class in middle school and high school. I found art class fun but art has never really stuck with me, I was never really good at it and that frustrated me. When I was assigned to go to the art gallery I was excited to see the art and be and try to become more familiar with art, with that…
