Stage One - The Chicxulub Impactor Origin Theory and how Asteroids enter the Earth's Atmosphere. Origin Theory The Chicxulub Impactor is an asteroid whose origin is unknown. A theory orchestrated by David Nesvorný, William F. Bottke and David Vokrouhlický however suggests that it is part of the Baptistina family of asteroids which was the result of a collision in the Asteroid Belt 160 million years ago (2). This theory is supported by the evidence of carbonaceous material that is present in…

alloys (RSC, 2016). Most of these alloys are used in the die-casting industry and in the production of brass, aluminum solder, nickel silver, or bronze (RSC, 2016). Zinc is also used in the formation of useful compounds, such as zinc oxide or zinc sulfate; these compounds can then be used in an array of product such as paint, cosmetics, pharmaceutical products, soap, rubber, batteries, x-ray equipment, or even florescent lights (RSC, 2016). Refer to Figure 3 in order to compare the first and end…

This patient was identified during the dietitian’s screening process for two different reasons upon her admission. There was a consult for this patient from the physician to provide nutrition education on a low sodium diet, as well as an alert from the RN due to the patient’s low Braden score and because she appeared cachectic/malnourished. I was given this patient by my preceptor to provide the nutrition education as well as complete her initial assessment. When I visited the patient she had…

Agarose Gel Electrophoresis Since the discovery of the four classes of macromolecules (proteins, lipids, carbohydrates, and nucleic acids), researchers and biochemists have fine-tuned methods that reveal structural information about each of them. Different structural properties determine different functions and chemical properties, and scientists have developed intricate techniques to observe, quantify, and isolate molecules based on their aforementioned properties. Agarose gel electrophoresis,…

contact with a substance. 4. During a flood, the labels from three bottles of chemicals were lost. The three unlabeled bottles of white solids were known to contain the following substances: strontium nitrate, ammonium carbonate, and potassium sulfate. Explain in great detail how you could easily test the substances and re-label the three bottles. (Hint: Ammonium ions do not provide a distinctive flame color). To easily test the substances and re-label the three bottles you could…

Animals have been one of the many test subjects used in science for years. Animal experimentation has scientists and citizens debating about whether it is a good thing or not; the talk about this issue has increased since new conducted scientific research, technology advances, and more people are concerned about animal welfare. Consider a cute little dog that has been in a family for several years. The family dog has gone missing. He is lost and roaming the streets in search for his owner.…

18 Home Remedies for Dry and Rough Hands 1. Milk cream Milk cream is one of the best remedies for a dry and rough hand. It has a high-fat content which provides the needed moisture to the dry skin. In addition, the lactic acid present in milk exfoliates the layer of dead skin cells and exposes soft and hydrated skin. Take some fresh milk cream and rub it gently on your hands for a few minutes. Let it stay for 10 minutes and wash your hands with warm water. 2. Olive oil Olive oil is another…

ply roofing system is made out of thermoplastic polyolefin membrane, which consist thermoplastic polyolefin top fly compound, TPO polymer base and polyester-reinforced fabric center. TPO fabric also uses fillers made out of carbon fiber, Metal Oxy Sulfate, wollastonite and fiberglass as well as EPDM and ethylene-propylene rubber. The TPO membranes can only be installed on flat or near flat roofing surfaces to create a water runoff and prevent leaks. The growing popularity of TPO roofing has seen…

In this study, we developed an anthracene-based fluorescence PET sensor (AMG) was developed for detecting high pH values and water content in organic solvents. A guanidine group as a proton receptor was covalently attached to an anthracene fluorophore to afford highly polar AMG, with reasonable solubility in highly basic solution. The fluorescence of AMG increased almost linearly with decreasing pH in the range 11.0–13.0. AMG also exhibited a fluorescence turn-on response to water in various…

Poison in Disguise Food—it is loved by all, required for life, but widely abused. The food industry has come under attack, especially in the last few decades, by nutritionists and doctors concerned by the overwhelming health problems in the developed world. Diabetes, heart disease, and obesity are just a few of the myriad issues impacting Americans today. Consumers must become educated on food labeling so that they can avoid foods dangerous to their health, and become more active in demanding…
