CHAPTER I INTRODUCTION Background of the Study Mangrove swamps are forested intertidal ecosystems that occupy sediment-rich sheltered tropical coastal environments. By trapping and stabilizing fine sediments‚ mangroves control the quality of marine coastal waters. Aside from maintaining coastal food webs and populations of animals‚ mangroves have an important role in pollution control through their absorptive capacity for organic pollutants and nutrients‚ and they play an important role in storm

Aspirin Background Aspirin Aspirin‚ or acetylsalicylic acid (ASA) is a salicylate drug‚ and is generally used as an analgesic (something that relieves pain without producing anaesthesia or loss of consciousness) for minor aches and pains‚ to reduce fever (an antipyretic)‚ and also as an anti-inflammatory drug. Aspirin works by prohibiting biological substances such as prostaglandins. Many different prostaglandins exist in the human body each serving a plethora of physical functions.

Nitration and Purification of Bromobenzene Abstract: An electrophilic aromatic substitution reaction was performed on bromobenzene with nitric acid producing both 2-bromonitrobenzene and 4-bromonitrobenzene. Products of the reaction were purified through multiple recrystallizations and column chromatography creating multiple crops of a yellow powder. The percent yield of products was determined to be 51%. The melting point of Crop 1 was found to be 110-115 °C‚ and Crop 2 was found to be 37-90

14 may be a possible EEC. Moreover‚ the calculated compensation temperature by inverting the straight line slope‚ T comp = 57.9 ºC‚ is higher than the average experimental value‚ T exp = 32.5 ºC. This great difference between these two values of temperatures might reflect the existence of real EEC rather than experimental error [58]. Another evidence of EEC is the approximate constant ∆G # with a significant change in both ∆H # and ∆S # . Finally‚ EEC was also investigated by using

This relationship is exemplified by 9-fluorenone?s high Rf values‚ and a strong affinity towards the stationary. phase. The symposia are.

Abstract A natural polyphenolic compound Quercetin was extracted from widely available and consumed plant Allium fistulosum which has shown promising chemo preventive and chemotherapeutic activities in cancer. In this study‚ quercetin is encapsulated and loaded onto PLGA (Poly lactic glycolic acid) microspheres using double emulsification methodology for improving its efficiency in cancer therapy. Quercetin is extracted and purified using chromatographic and nuclear magnetic resonance (NMR) techniques

Kao and Charles Hockam : For long range communication system the loss limit was set to 20 dB/Km (was ~ 1000 db/Km or higher at that time!).

UHSC mixture proportions were developed using local materials so that UHSC may be made more affordable to a wider variety of applications. Specifically‚ local sand with a top size of 0.0236 in. (600 μm)‚ and locally available Type I/II cement and silica fume were used in this research. Each of these material selections is seen as an improvement in sustainability for UHSC. Two mixtures (one with and one without fibers) were recommended as the UHSC mixtures. The greatest compressive strengths obtained
