Humanity is in a race against time as the threat of global warming looms on the horizon. To prevent catastrophe, the nations of the world must focus on decreasing their carbon dioxide output by as much as possible. While agriculture and industrial processes have a high carbon footprint, fossil fuels are by far the biggest contributor to anthropogenic global warming. Therefore, the best way to mitigate the problem is to replace coal and oil with cleaner sources of energy. Solar and wind power are…

pay off the Vikings in hopes of preventing farther attacks on their subjects. This did backfire on what is now Paris, in 841CE Frankish King Charles payed a Viking leader 7000 livres of silver and gold for the freedom of Paris, this would be the equivalent of 17,429.30US dollars (without inflation). After hearing tales of how generous the Frankish king was Ragnar Lodbrok attacked the city of Paris in 845 CE with 120 long ships and 5000 Viking warriors lead by in hopes of receiving more than was…

Nuclear power us one of the biggest and best power sources known today. Nuclear fusion and fission makes a lot of excess usable energy. It produces a lot more energy than wind, solar, coal, or fossil fuels do, and they actually are better for the environment than coal or fossil fuels, producing helium rather than carbon monoxide.In short, nuclear power is a good idea because we can take care of the nuclear waste, the reactors have better safety measures and protocols than normal factories, is…

drug release study The prepared econazole nitrate nanoparticles obtained from the nano-spray dryer were suspended in isotonic buffer pH 7.4 and were then tested for drug release by dialysis method in isotonic buffer with pH of 7.4. Nanoparticles (equivalent to 2.5 mg of drug) were instilled in dialysis bag containing 1 ml isotonic buffer with pH value of 7.4 and was secured by two clamps at each end. The dialysis bag was completely soaked in a vessel containing 100 ml of release medium with…

Coffee is a complex mixture of chemicals that provide significant amounts of chlorogenic acid and caffeine. Coffee contains over a thousand different chemicals, including carbohydrates and vitamins. “Caffeine is naturally found in coffee beans, cacao beans, kola nuts, guarana berries, and tea leaves”, (Heckman, et al R77-87). A drug referred to as caffeine stimulates the central nervous system and causes increased alertness. These are all products that are used in common beverages that people…

cells differ from mammalian cells due to highly developed cell walls outside the cytoplasmic membranes that provide structural integrity and shape to the cell. Bacteria live in dilute aqueous environments, which causes an intracellular pressure equivalent of 10-25 atm. Without the structural support of the cell wall, the cell is susceptible to lysis and osmotic rupture due to osmotic rupture due to turgor pressure. Figure 1: Comparison between gram-positive bacterial cell walls and…

Why does it take so long to get through airport security? It is because airports have to have more security now than they used to so people have to go through metal detectors as well as backscatter systems. Backscatter systems are being introduced throughout the United Sates. Flying is a very dangerous mode of transportation, partially because people are in a confined space and have no option of leaving once the plane is in the air. This means that extra precautions must be taken to ensure the…

ambiguity and dishonesty that they present to the audience. The kids, being the feminine, would be able to detect that something was wrong through their intuition. They always know what the leadership are planning regardless - to lie to them would be equivalent to telling them that dragons were going to come down from the sky and barf rainbows. The kids most definintely aren’t idiots. The audience, on the…

GENTAMICIN The drug selected for study is Gentamicin. Gentamicin is an aminoglycoside antibiotic composed of a mixture of related Gentamicin components and fractions and is used to treat many types of bacterial infections, particularly those caused by Gram-negative organisms. Isolation and Preliminary studies 2 demonstrated that it is a mixture of basic, water soluble antibiotic containing the aminocyclitol 2-deoxystreptamine and two additional amino sugars. Chromatographic separation of…

had sensory problems including optic nerve hypoplasia (n=3) and macular hypoplasia secondary to oculocutaneous albinism (n=2). Mean spherical refractive error before and after surgery was -2.16 ± 1.36 and -0.1 ± 0.35, respectively, mean spherical equivalent was -2.82 ± 1.65 and -0.26 ± 0.25, and mean astigmatism before and after surgery was -1.33 ± 1.14 and -0.31 ± 0.51, respectively (P<0.001 for all parameters). None of the patients required enhancement surgery and epithelial healing was…
