Abstract As one of the most popular analgesic and antipyretic, especially for pregnant women and children, acetaminophen is available over the counter in many forms. When consumed over long periods of time or in high dosages, acetaminophen has serious side effects including liver damage and other organ damages, therefore an effective quality control method of analysis. Here a method using cyclic voltammetry to analyze the concentration of acetaminophen in a liquid suspension Publix brand…

CHAPTER 4 RESULT AND DISCUSSION 4.1 Preparation of Bis-Thiourea Derivatives The mixture of heptanoyl chloride and ammonium thiocynate with 1,4-phenylene diamine appeared as homogeneous solution. White precipitate was formed immediately when the solution was filtered into the beaker containing ice cubes. Then, the precipitate was filtered again and rinsed by ethanol before being dried in the desiccator. The physical data of the synthesized bis-thiourea derivatives are shown in Table 4.1.…

ANALYTICAL METHODS Determination of λ max Gemifloxacin mesylate λ max is determined by preparing one standard concentration of 10μg/ml and scanning should be done. Preparation of 0.1N HCL 8 ml of hydrochloric acid is taken in 1000ml volumetric flask and dissolved with distilled water and then make up to 1000ml with distilled water. Standard graph of Gemifloxacin mesylate: The λmax of Gemifloxacin mesylate in 0.1N HCL was scanned in UV-Visible Spectrophotometer and found to have maximum…

Chronic heart failure patients have periodic episodes of clinical decomposition which doesn’t impair only the life quality but also consume substantial health care resources like costs of hospitalization [1]. In order to reduce the severity and frequency of these clinical events heart failure management programs is developed, but their efficacy may be restricted by difficulty of physician in recognizing patients at imminent risk [2]. Dependable estimate of these events avoids clinicians to…

CHAPTER-1 INTRODUCTION OVERVIEW Multimodal biometric face and fingerprint recognition using XOR configuration system based on adaptive principal component analysis and multilayer perception. Multimodal biometric is a combination of physiological and behavioral characteristics into a single biometric system. The important cause to combine singular traits is to get improve recognition rate and accurate result. This is done when feature and trait of biometric are statistically independent. The…

The human skin is responsible to act as the first line as defense in protecting our body from the external environment and harmful materials such as bacteria. Archaea can be found on human tissue or epidermis, but however, their affluence is unknown and rarely studied. The number of microorganisms on the human epidermis is dependent on a variety of things. For example, the location, presence of moisture, age, sex, immune system and living conditions play an important role in the composition of…

Fourier Transform Infrared Spectroscopy (FTIR) It is one of the classical techniques used routinely to derive information regarding the various bond types, the presence of different functional groups and interaction among them. FTIR spectroscopy provides opportunities…

Kate Byrne DT299/4 CHEM 4128 Applied Physical & Analytical Chemistry Assignment Liquid Chromatography High Resolution Mass Spectrometry Hyphenated Techniques The term “hyphenated technique” was introduced by Hirschfeld in 1980. It refers to the combination of a chromatographic separation technique and a spectroscopic detection technique to form a new, more efficent instrument. The technique which will be discussed in this case is LC-MS. The aim of combining both techniques is to purify and…

10.1 SUMMARY The aim of the present investigation was to formulate Raloxifene Hydrochloride Liquisolid compacts, with coadministration of a bioenhancer, for oral bioavailability enhancement. The reason for poor bioavailability (2%) of Raloxifene Hydrochloride is low solubility (100μg/mL) and high hepatic first pass metabolism. According to BCS, Raloxifene Hydrochloride is considered as Class II drug, lipophilic and highly permeable compound. Therefore, formulating Liquisolid Compacts bearing…

I thought I’d attempt to briefly summarize what we’ve read and discussed, so far. Marx’s Project and Context Marx was essentially trying to uncover the reason why society was the way it was. The 19th century was a time of tremendous political and social change. New technologies and forms of organization (the factory system) had significantly increased the productivity of manufacturing in all across Europe. Alongside this was the enclosure of common lands, which pushed peasants and craftspeople…
