In the opening seen of Unwind by Neal Shusterman, Connor and his girlfriend are discussing his options over the busy highway. If I hadn't read the book prior to this, I would have been extremely confused as to what they were discussing. Which was most likely the authors goal. Reading through it a second time helped me look further in the details. In this story Connor is being unwound. He found this out when he was he sneaking through his fathers office and found 3 plane tickets, there are 4 of…

approaches to the frescoes they were responsible for and as a result the restoration team needed to approach each work differently. Modern restoration techniques called for the use of polyvinylacetate resins in place of bronze pins. Places where pigments were not well adhered to the surface were secured with the use of a diluted acrylic resin…

In researching Black|Up cosmetics, I began with a different approach. When I researched this company within any database, I found little to no information. At first, I assumed that the lack of information was because Black|Up is a foreign company. Its base location is in Paris, France.

result that showed the higher chance of being the unknown. All three genus showed that they have different type of motility organism, motile and non-motile. Pseudomonas shows that it also has organisms that can have both yellow and other florescent pigment as their morphology. The organisms in this genus can also be oxidase positive or negative. In the same genus, some organism can convert glucose to acid and some can’t; and some can reduce nitrate while other can’t. It lacked the result for…

For this second assignment, I have chosen to talk about dry media and wet media art works. “The dry media, which include metalpoint, chalk, charcoal, graphite, and pastel, consist of coloring agents, or pigments, that are sometimes ground or mixed with substances that hold the pigment together, called binders.”(p.165) I selected the composition “Study of a Woman's Head or the Angel of the Vergine delle Rocce, 1473” by Leonardo da Vinci. This is merely just a sketch of a woman's head from the…

However those affected with Battens has a rapid and destructive accumulation of the pigment. Besides that there is still little understanding behind the specific reason or the biochemical mechanism that is involved in…

Ethanol disrupts membranes by a number of methods. In particular what you must remember is, the size and fluidity of the membrane has a lot to do with the outside and inside environment. This environment consists of how much water, salts etc are in the cell versus out of the cell. Adding ethanol disrupts much of this. 1. Ethanol is permeable to cell membranes. Because of the nature of ethanol as a chemical is it able to get into the cell very easily. This disrupts the balance of the…
