Formal Report no. 1 Synthesis of Aspirin Chemical Principles Aspirin is most widely sold over-the-counter drug. It has the ability to reduce fever (an antipyretic)‚ to reduce pain (an analgesic)‚ and to reduce swelling‚ soreness‚ and redness (an anti-inflammatory agent). Much of this is believed to be due to decreased production of prostaglandins and thromboxanes. Aspirin’s ability to suppress the production of prostaglandins and thromboxanes is due to its irreversible inactivation of the cyclooxygenase (COX)

Lab 3: Grignard Synthesis Objective: The goal of this lab is to synthesize a Grignard reagent from bromobenzene and magnesium metal in diethyl ether. This same Grignard reagent would then be used to prepare a tertiary alcohol and then purify and characterize the product. Table of Reagents: Name Chemical formula Melting Point Boiling Point Density Safety Hazards Diethyl ether C4H10O -116.3°C 34.6°C 0.7134 g/ml Flammable Bromobenzene C6H5Br -30.6°C 156°C 1.5 g/ml

Lab 1: Synthesis of Aspirin Introduction: The purpose of this lab was to demonstrate the ability to easily alter the molecular structure of a compound to greatly increase its utility. In this case‚ an acetyl group was added to salicylic acid‚ a naturally occurring compound with significant pharmaceutical value. Without the addition of the acetyl group‚ salicylic acid is an irritant to the gastro-intestinal (GI) tract. Once the acetyl group is added via a simple reaction‚ acetylsalicylic

Comforting the Neonate; application of the Comfort Care Theory Introduction An anonymous author once said‚ "In the last stages of a final illness‚ we need only the absence of pain and the presence of family." The comfort care theory by Katharine Kolcaba exemplifies this by creating a baseline of quality care that both nurses and doctors can utilize in providing care to a dying patient. Comfort has been called a distinguishing characteristic of the nursing profession yet‚ until Katharine Kolcaba‚ had never

Sarah Khan Bivins-5th April 20th‚ 2013 Protein Synthesis Every day‚ you take in an abundance of different biomolecules; one of them being proteins. Have you ever wondered how proteins are made? They don’t just grow from a tree or fall from the sky‚ they are made through a process called protein synthesis. Protein synthesis is broken up in two two steps: transcription and translation. Transcription starts inside the nucleus when the DNA is unzipped by helicase. Following that‚ the mRNA nucleotides

As I have progressed from project two to project three my theory of communication has evolved as composing genres put a new dynamic component in my theory. From project two‚ my theory of communication was essentially nurses are responsible in all areas of communication‚ whether it is a change in the audience‚ constraints that occur‚ the clarity of their content or any rhetorical situations that happen. Nurses are the main entity within their medical community to provide accurate information and superior

Theory offers structure and organization to nursing knowledge and provides a logical way of gathering information to describe‚ explain‚ and predict nursing practice. Theories describe and explain nursing and the purpose of nursing to differentiate it from other caring professions by setting boundaries. (McEwen & Wills‚ 2014‚ p. 25). The use of theories gives nursing its own identity and takes away the task-oriented description of the past. Kolcaba’s theory of comfort is a theory that is used throughout

result in criminal charges being filed. If carried out by individuals unskilled at chemistry they could result in serious bodily harm. MDMA ("Ecstasy") is a semi-synthetic compound which can be made relatively easily from available precursors. Synthesis instructions exist which can be followed by an amateur with very little knowledge of chemistry. However‚ people with less than 2 years of college chemistry experience would probably not be capable of sucessfully synthesizing MDMA‚ and would either

Grand Theory Written Assignment Natalia V. Hayes Maryville University Grand Theory Written Assignment In this assignment I will compare and contrast four theorists from one of each types of grand theories: Dorothea Orem from Needs theorists‚ Imogene King from Interaction theorists‚ Sister Callista Roy from Outcome theorists‚ and Jean Watson from Caring/Becoming theorists (as identified by Meleis‚ 2012). Then I will compare and contrast all four theorists within following: educational
