ABSTRACT: Terpolymer / kaolinite microcomposites were synthesized by 2:2:1 molar ratio of aniline, anthranilic acid and o-phenylenediamine monomers, respectively using various percentages of kaolinite clay via modified in situ oxidative ter-polymerization. The results were confirmed by FT-IR and UV-Vis absorption spectra of terpolymers / kaolinite composites. The thermal behaviour of the terpolymer and composites was studied. Terpolymers / kaolinite composites were thermally more stable than…

Organic Acids An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group –COOH. Sulfonic acids, containing the group –SO2OH, are relatively stronger acids. Alcohols, with –OH, can act as acids but they are usually very weak. In general, organic acids are weak acids and do not dissociate completely in water, whereas the strong mineral acids do. Lower molecular mass organic acids such…

Detection of Zika virus Introduction: Zika Virus, also referred to as ZIKV, has become a global health epidemic. The World Health Organization declared a Public Health Emergency of International Concern earlier this year due to the increase of areas affected by Zika. Originating in the Zika forest of Uganda, ZIKV was predominantly found in areas of Africa and Asia. However, there have recently been reports of more than 36 countries with cases of the virus. (Chen, 1), (CDC) ZIKV is a single…

3. Results and discussion 3.1 Microstructural characterization The Roman spectrum of Cr-DLC coating was shown in Fig.1. The overlapped D peak and G peaks located at 1363cm-1 and 1564cm-1 were obtained after fitted with Gaussian curves, respectively. It’s well known that the content of the graphite crystal was closely related to the value of ID/IG [22]. And the ratio of intensity between D peak and G peak (ID/IG) of Cr-DLC coating could be calculated by the fitted curve. The value of ID/IG was…

2.1 Ageratum conyzoides Ageratum is derived from Greek word, which is “a geras” meaning non-aging, referring to the longevity of the flowers or the whole plant. The word “conyzoides” is derived from word “konyz” meaning resembles (M.X et al., 2016). Ageratum conyzoides is belongs to the Asteraceae family. Plant species in this family are herbaceous plants which trees and shrubs are rare. This plant is very common in West Africa and Asia. It has softly hairy stems and leaves, erect and branched…

Patient should use of silica gel or air midsoles as well as polyester or blend (cotton-polyester) socks to prevent blisters and keep the feet dry to prevent trauma. Proper footwear is important and must be emphasized for individuals with vascular disease.17 Physical therapist must monitor closely for blisters and other potential damage to their feet, before and after exercise. 17 She has adhesive capsulitis and for that, Physical therapist check for sensation before treatment of hot modalities.…

This chapter discusses about the health hazard and hygiene in the workplace. Hazards can be found in every workplace. Hazard is generally anything that makes you in a dangerous situation. Health hazard is means that the hazard brings negative effect and harm to the health which is may cause measurable changes in the body. There are many hazard in the workplaces have the potential to harm workers short-term and long-term health result in diseases, disorders and injuries (Alison et. al., 2008).…

INTRODUCTION In the recent advancement of targeted therapeutics that was coupled with new approaches in target identification have accelerated the need to design small compounds with drug like properties [1]. Quinoxaline is well known for its broad coverage in the field of medicine as well as for its application in the pharmaceuticals as they have shown wide range of biological properties such as antimicrobial [2], antibacterial [3], antitubercular [2, 4], antiprotozoal [5] , anti-candida [2, 6]…
