Amoxicillin: A Review of Two Articles

The purpose of this paper is two examine two studies on the topic of the efficacy of amoxicillin or amoxicillin clavulanate as treatments for otitis media. The paper will describe the two studies, point out the major differences, and concludes with speculation as to why one study recommends the broad-spectrum penicillin antibiotic whereas the other recommends a wait and see approach.

Design of the Studies

Both the Dutch study, Damoiseaux et al. (2000), and the Finnish study, Tahtinen et al. (2011), used a randomized, double blind, placebo-controlled design to test the efficacy of amoxicillin or amoxicillin clavulanate. The inclusionary criteria in the Damoiseaux ...

An acid is a solution that loses hydrogen ions. Common household acids include vinegar and citrus fruit juice. In contrast, a base is a solution that gains hydrogen ions. Acidic substances often taste sour whereas bases taste bitter and feel slippery. Since the tasting or touching of acids and bases can be harmful to human health, Occupational Safety and Health Administration (OSHA, 2013) recommends the use of indicators to test for the acidity or alkalinity of substances. Typically, indicators such as litmus paper change color when exposed to acids or bases (Stanley et al., 2015). As such, the present ...

The Brady campaign to prevent gun violence uses gun crime statistics to try to show the high rate of crime because of high gun possession. Predictably, this organization will use gun crime statistics to show the dangers of having many guns and the need to control gun ownership. The NRA on the other hand puts forward the argument that incidences of gun violence decrease if more guns are in the hands of the population. Clearly, statistics should prove one side of the argument wrong because the numbers are the same. However, each side tries to use the statistics that ...

Introduction

Blood behavior conforms to specific scientific principles and therefore, professionals trained to perform bloodstain pattern analysis can analyze the blood evidence in a crime scene and come up with conclusions as to how the blood shedding happened. The stains may appear to have a random distribution in a crime scene, but the analysts can study the spatter patterns, transfers, and other marks. From the physical evidence, the investigators recognize and interpret the patterns to determine how they were created. These marks are then categorized to recreate the sequence of events that occurred following the bloodshed. Blood stain pattern analysis, ...

Electrophilic Aromatic Substitution to yield 4-Bromoacetanilide

Introduction Halogenation is a common process in organic synthesis. It is used in industrial and research synthesis as halogenated compounds are used for numerous widely used goods, including plastics. The lab aimed to perform monohalogenation of acetanilide. The reaction is specific since it is performed without catalyst. The typical halogenation is realized in presence of Lewis acid. Halogens molecules are electrophilic, and do not actively react. In presence of Lewis acid, the interaction is rather active.2 The lab used catalyst-free halogenation. The acetanilide molecule contains the acylated amine. As a result, the electronic density is shifted towards the amine ...

The Sultanate of Oman, is, a unique country filled with different statistics both in marriages and births. But, compared to its western counterparts like the United States, perhaps, the statistics regarding the population growth, and, rate of marriages in Oman differs greatly. Oman, an Asian country, varies greatly in terms of birth and death statistics. Over the course of a 10 year period, Oman, saw its own birth and death rates actually improve significantly. Beginning in 1990, Oman, had an under 5 mortality rate of 39, but, over the course of the next 5 years it shrunk to just ...

Lab 2 – Water Quality and Contamination

Abstract In this lab, the water quality, contamination, and treatment were investigated. The ability of contaminants (oil, vinegar, and laundry detergent) to remain in the water after passing through the ground was examined. Also, the simple filtering procedure was assessed for its effectivity in purifying water contaminated with soil. The quality of tap water, Fiji, and Dasani bottled waters by the content of ammonia, chlorides, iron, phosphates, total alkalinity, total chlorine, total hardness, and pH was analyzed and compared. All of the studied contaminants proved to remain in the volume of water after passing through the soil; the proposed ...

The periodic table of elements, by far, stands among the most notable discoveries in the history of chemistry. Nowadays, probably everyone who has ever heard about chemistry heard about the periodic table of elements. Its implications on the scientific world are so enormous that it has even leaked out to the general public and have become associated with the chemistry itself. This is not surprising considering the scientific strength of this instrument. Using the periodic table, many characteristic properties of the elements can be predicted and many phenomena can be explained. This discovery put so much scientific knowledge together, ...

International Management Abstract The film and music industry have both evolved drastically during the past decades. From vinyl records to CD’s to digital mp3 files in the music industry, and from cassette tapes to mp4 files in the film industry. The evolution in both the film and music industry is most likely a result of the practicality demanded by the society. Individuals often seek easier and cheaper alternatives. In both of these relevant industries, the most practical solution is of course to have instant access to demanded content that is merely software and requires no type of disc. ...

For Basket Currency Regime

Thesis Statement Any country can choose on whether to or not to peg their respective currencies on another different currency. This decision is influenced by various factors. Pegging a currency against another currency is driven by some reasons and will have several benefits and disadvantages. The other alternative is the use of basket currency regime in the country. This has some costs, benefits and constrains which need to be considered . There are several currency regime blocks that will always influence these decisions. In China, the Chinese Yuan was strictly pegged on the US dollar for a very long time. ...

Summary of the WSJ article

The article by the Wall Street Journal illustrates the drop in oil prices over the years in the United States and the global market. According to the article, the oil market is not attractive to investors all over the world due to the dropping prices of fuel over the years. Oil prices have dropped significantly to settle at very low prices per barrel. The US economy currently regards oil as one of the worst performing commodities in the country which is unlike the previous years where oil was one of the most profitable investments. According to the article, the ...

Diet Evaluation with Resolution Drops

When people in general think of the word diet, their minds relapse to some strange foods or weird exercise routines. However, that is not always the case and in some instances incorrect. A person can be placed on a diet with no exercise at all and can omit having to eat only a certain type of food. The thought of accepting such things is hyper-stereotypical and should not be considered seriously. A diet was examined and researched and it is called the Resolution Diet. These are drops that are placed under the tongue and the bottle should last the ...

Introduction

Osmosis is the process by which water molecules move from a region of low concentration of solute to a region of high concentration of solute through a semipermeable membrane (Van 3). Osmosis therefore can define the movement of water in and out of the cytoplasm of a cell. A solution with a higher concentration of solute molecules than that of the cell cytoplasm is said to be hypertonic to the cell. On the other hand, a solution with a lower concentration of solute than that of the cell cytoplasm is said to be hypotonic to the cell. Purpose: The ...

The increased pace of job globalization, in developing and developed countries, has focused attention on outsourcing as an object of both praise and criticism. The loss of job opportunities (locally), lower quality products and/or services and, not least, further imbalances in income pay are all outcomes critics of outsourcing cite. On upside, job outsourcing, particularly at a global level, is apt to enhance productivity, lower costs and, for one, enhances core efficiencies for outsourcing companies, according to supporters of outsourcing. If anything, cost assumes center stage in a decades-long debate now on outsourcing. There are, however, more in outsourcing ...

Introduction

Following the drops witnessed with the overall prices within the oil industry, it has been recorded that majority of the dependent industries have been reported devaluation in both their asset bases and their stock items. This is the suggestion of the Bushee and Miller (2013) on presenting the oil industry as one industry that is heavily depended upon by a majority of the sectors within commerce and industrialization. Suggestively, this is true based on the use of oil within the manufacturing sector, the energy and allied sectors, the transport sectors, and production industries. With this highlighted, the effect of ...

Section

Introduction The purpose of this lab was to investigate the stoichiometry and find out the mole ratios of simple acid-base reactions experimentally. The reactions studied in this experiment were the following: HCl + NaOH → H2O + HCl H2SO4 + 2NaOH → 2H2O + Na2SO4 H2SO4 + Ba(OH)2 → 2H2O + BaSO4 HCl + Ba(OH)2 → 2H2O + BaCl2 In the chemical reactions, the compounds react in distinct molar proportions or ratios which are constant to the peculiar reaction. The ratios determining the quantities of substances reacting are called stoichiometric coefficients. The reactions between strong acids and bases are relatively simple and non-reversible reactions the “end” of ...
