Menu Name: elastomeric roof coatings Article Summary: A water proof and flexible surface coating will prolong the life and improve the appearance of some roofs. Article: Roofs protect buildings, contents and people from the elements. What people may not realize is that many roofs themselves also need protection. Many variables, such as materials used, quality of construction and climate, determine how to keep a roof from deteriorating prematurely. New Orleans roofing professionals can…

Rain is much more than weather in literature. In Julia Alvarez’s In the Time of the Butterflies, rain is used to symbolize a time of trouble and confusion that has washed over the country, but the destructive element of the weather is also used to symbolize the new start that is to come for the Dominican Republic. In Minerva’s chapter six, a large section of the chapter is titled “Rainy Spell.” When Minerva says “The rain comes down all morning, beating against the shutters, blurring the sounds…

Global warming is turning into a huge problem today. Oil spills are happening, more and more pollution is being put into the air and causing problems with the ecosystem. Citizens see that this is evolving more and more each day and the government is just ignoring it for “bigger problems”. The ocean is being polluted and millions of dollars are spent almost every year trying to fix it the problem temporarily. The Democrats would like to fix all these environmental problems but they need to pass…

Abstract: The Grignard reaction was successfully accomplished. An amount of 1.20 ml of 2-methyl-2-pentanol was collected, and 9.60% yield was calculated based on the theoretical yield. Despite the low amount of 2-methyl-2-pentanol, its identity was confirmed by comparing the experimental refractive index and infrared spectrum to the literature refractive index and infrared spectrum of 2-methyl-2-pentanol. Statement and purpose The purpose of this experiment is to synthesize a specific alcohol…

According to Regis, the reason why there were two layers is because the two compounds in the solution were immiscible. This means that they don’t dissolve each other. Therefore the aqueous solvent will sit on top and the solvent that is immiscible with water, the organic solvent, will sit on the bottom. The reason why the percent recovery wasn’t higher was because maybe not all of the upper aqueous layer or all of the organic layer was extracted all the way. If some of the upper layer was mixed…

industrial activity all increases the speed of water and also changes the hydrology of the wetlands. Louisiana has become a “sacrifice zone” for the countries’ energy…

In 1798, Thomas Malthus theorized that population growth was an impending danger that if not properly checked would result in an unfavorable outcome for human society. The main idea behind his theory was that the accelerated growth of the human population is unsustainable and that we are set to eventually outpace our ability to produce food, leading to a major catastrophe. Two hundred years later, Thomas Malthus’ theory fortunately has not come to fruition, however, it is still a major topic of…

spots surfacing near the surface of the crust. Examples of these hot spots manifest themselves as volcanoes, geysers, and hot springs. After the heat reaches the surface the naturally-occurring hot water and steam can be trapped by energy conversion. This then allows us to convert the heat energy from the water…

General procedure: One equivalent of spacer was coupled using 2.4 equivalents of inhibitor, 0.18 equivalents of copper sulfate, 0.36 equivalents of (+)-sodium-L-ascorbate, in a mixture of 10% H2O in DMF, 24 mL/mmol spacer. The mixture was placed in the microwave for 30 minutes at 80oC Pro6 Spacer (10) (30 mg, 0.036 mmol) and 18 (36 mg, 0.087 mmol) were dissolved in 778 µL DMF. Copper sulfate (1.62 mg, 0.006 mmol) and sodium-L- ascorbate (2.57 mg, 0.013 mmol) were dissolved in 86 µL H2O. The two…

Powdered milk. Whole milk is the baseline comparison since it is the milk that has been tempered with the least. The 2% and 1% milks have had most of their fat removed. Powdered milk goes through an evaporator, removing most of its butterfat and ¾ of its water. Both 2% and 1% went through another process in which fat was removed from the milk after placing it into a “centrifugal separator” (Christine Gallory, 2015). Hypothesis: If different types of milk were to go through the curdling process,…
