Polymer

Phospholipids Phospholipids are a kind of lipid that are well suited to both their biochemical and physiological function. They comprise of a glycerol backbone with a phosphate head and two fatty acid tails. The tails are hydrophobic, meaning that they do not interact with water. When a group of phospholipids come into contact with water they arrange themselves in a bilayer that hides the hydrophobic parts from the aqueous surroundings. This leaves the head of the phospholipid in contact with…

Lafora disease is a rare, inevitably fatal, autosomal recessive, progressive myoclonus epilepsy. Being autosomal recessive, the disease is most commonly seen in communities that practice consanguinity. The onset of the disease occurs within the first two decades of life, with an average life span of 10 years following diagnosis (Monaghan & Delanty, 2010). Lafora disease is characterized by myoclonic and tonic-clonic seizures and neurological dysfunction, such as dementia (Monaghan & Delanty,…

and loses it’s biconcave shape. By using transmission electron microscopy, it is evident that sickle shaped cells have groupings of fibers that run along the long axis of the cell [9]. The fibres, which have a rope like structure, are made of 14 polymer strands [9]. Unlike erythrocytes, sickle cells differ in density. The least dense sickle cells are more predominant because there are a greater number of reticulocytes (immature red blood cells) that have less hemoglobin, which means there are…

The future of car engines In October 1973 the oil crisis began "when the members of the Organization of Arab Petroleum Exporting Countries (OPEC) proclaimed an oil embargo" (Wikipedia, n.d.). This action was in response to the United States supplying weapons to Israel in their war against Syria and Egypt, which was called the Yom Kippur war. As a result of this embargo, the United States passed a law called the "Corporate Average Fuel Economy (CAFE)", the purpose of which was to "reduce energy…

In a collaboration between Céline and Stella McCartney, Chinatown Plaid was released as part of a 2013 Fall collection. The tailored coats of bright plaid bares resemblance to large, plastic woven tote bags, having appropriated not only its red, white, and blue print but also its rigid form and frayed trimming. However, in contrast to the garments’ name, the visibility of these bags extends beyond the working class immigrants in Chinatown and other districts characterised by large migrant worker…

My first research experience started when I participated in bone scaffold designing project at the Cooper Union in Spring 2012, under the supervision of professor David Wootton at Cooper Union Department of Mechanical Engineering. The purpose of this study was to design and manufacture bone scaffold for orthopedic trauma, especially for segmented bone fracture. I worked with a senior mechanical engineering student who had been conducting the research as his senior capstone project. The first…

Much of today’s society thinks that hemp is bad because it has qualities similar to marijuana. When in fact, it is a very distant cousin of ganja and is not really like wacky-tabacky at all. Industrial hemp can be used in clothing, food/beverages, paper, building materials, plastics, fuel and chemical clean-up. It can help the economy by opening thousands of jobs and bringing in local money and we would not have to import it from other countries anymore. “A change in federal policy to once again…

The RNA World: The Implications and Problems it Presents Brandon Gutierrez Abstract The origin of life on Earth is a difficult topic to analyze with the limited data available in modern science. Many hypothesis have been suggested to explain how life may have arisen from an abiotic environment, but the topic is still far from fully understood. One generally accepted hypothesis to explain the origin of life involves an RNA world in which RNA was synthesized abiotically and carried out both the…
