The Importance of Chemistry Labs in Florida National University

Florida National University is one of the leading universities in the region. While it is replete with many facilities, it glaringly lacks a chemistry lab. Online laboratory exercises are no substitute to the actual experiential learning in a chemistry lab. Reid and Shah argue that the absence of the laboratory experience may leave students with perceptions of chemistry that would be very ‘abstract and theoretical’. While students might perceive that the theoretical understanding is gained at a relatively slow pace through lab work, it is undoubtedly true that the knowledge gained would stand in good stead in future professional ...

There is a lot of focus and puzzles on hypoxic drive in the modern society. What is hypoxic drive and what are the processes that facilitate it? Hypoxia refers to a condition where there is lack of oxygen in a part of the body or the entire body. In this condition, the patient’s body utilizes oxygen chemoreceptors rather than carbon dioxide to regulate the respiratory cycle (Greaves et al. 120). This essay discusses biochemical, physiological, epidemiological, and clinical evidence to support hypoxic drive in the chronic hypercapnia patient (Galvagno 58).

Introduction.

When teaching science, instructors use a specialized language that has many dissimilarities from the language that students generally use throughout the day (O’Toole, 2003). Each different occasion for language has a set of intrinsic purposes, values and characteristics, and the purpose of these different traits is to demonstrate the unique properties of that category of language. For example, in scientific language, there is an emphasis on precision in diction, as well as conciseness and clarity. No matter what the language is, writers hope to achieve a style that is comprehensible to its readers while remaining true to the aims of the ...

1) The scientific method is an organized approach used to explain why things happen or to predict what will happen. The scientific method aims to answer questions and problems objectively and accurately by conducting experiments. The first step in the scientific method is the definition of the problem. One has to have a specific problem which one wants to resolve. After defining the problem, questions must be asked. The purpose of asking questions is to limit the scope of the experiment. The questions will serve as a guide so that the experiment does not lose its focus. The question should be ...

- What is Lipinski’s Rule of Five and why is it important to drug design?

Lipinski's rule of five is popular as the Rule of five (RO5) or Pfizer's rule of five. It is a standing rule that evaluates drug likeness in determining whether chemical compounds that have certain biological or pharmacological activities have properties that make it a probable orally active drug for human consumption. This rule is on observing that many medication drugs have lipophilic molecules (Anastas 56). This means that the rule is applicable in drug discovery when lead structures that are pharmacologically active optimized. This increases the activity and compound selectivity insuring proper maintenance of drug-like physicochemical properties as illustrated ...

Scenario question Part 1

Following an intentional biological attack, many different disciplines and agencies would become involved in the investigation. In a case which local water supply has been determined to have been intentionally contaminated with a disease agent, what disciplines/agencies (public health and otherwise) do you think would be involved in the investigation, and what might their roles be? Why would epidemiology be important?

The operative concept in this scenario is intentional. The established evidence is one highly suggestive of a terrorist attack. Therefore, besides public health intervention the department of homeland security officials must intervene for safety of citizens. Next human resource should be ...

In his paper “Psychology as the Behaviorist Views It,” Watson (1913) points out what he believes to be the main issues of psychology as a growing science. Watson explains that psychology is concerned with the analysis of complex mental states and processes and reducing them to simple elements. An alternative approach includes taking several simple elements and constructing complex mental states from those elements. In both cases, the significance of external stimuli is often dismissed in studies, which also means no significance is attributed to behavioral data. That is why Watson argues that existing subject-matter in psychology should ...

Introduction

Spectrophotometry refers to a method that is employed in the determination of the amount of light that is absorbed by a chemical substance. In chemistry, the term spectrophotometry refers to the determination of the reflection or transmission characteristics quantitatively material through a function of wavelength (NIST, 2012). The spectrophotometry analysis is carried out through the light intensity determination as a beam of light passes through a tube containing the sample solution. The process of analyzing solution concentration using spectrophotometer utilizes the fact that light possesses a dual nature. This is where the light may exist either as particle or as a wave (Keller, 2003). Basically, ...

Certain elements involved in the geochemical and biogeochemical cycling are of great concern due to their limited availability both naturally or through industrial manufacture of the compounds involved in the cycles. Some of the processes involved are chemical reactions with other elements or substances. Some of these reactions are irreversible chemical reactions. This implies once the reaction has taken place, the elements are removed from natural cycle and they cannot be replaced again. As such, the more the cases of irreversible reactions, the greater the rate of reduction of these elements from the environment. Ultimately, there could be less ...

Disaster narratives in pharmacists’ journals usually describe accounts of inappropriate breach of medical dispensary, or involve issues regarding confidentiality. One recent article publication in Chemist & Druggist (2012), portrayed a situation in which a woman walks up to a pharmacy counter, hands the clerk a prescription bottle, demanding to know what symptoms the medicine is for (p. 278). The prescription is not hers, although most likely she is the caregiver for the elderly man who is homebound. In this case, the pharmacist must proceed quite cautiously due to striving to protect all of the confidential healthcare information passing through the dispensary. As one can ...
