Page No: 01-06
Abstract: The effect of UV-B radiation on pigments (Total chlorophyll, Chlorophyll a and Chlorophyll b) and biochemical contents ( Protein and Carbohydrate) of three species of Codium viz. C.dwarakensis C.de corticatum and C.tomentosum collected from intertidal and subtidal regions of Valai island, south east coast of India was investigated. The algae were exposed to UV-B (280-315 nm) radiation for 30, 60, 90,120,150 and 180 minutes and analyzed for pigment and biochemical contents. UV- B radiation inhibited 39% of total chlorophyll, 31% of chlorophyll a, 44% of chlorophyll b, 20% of protein and 10% of carbohydrate contents over control in C. decorticatum, . However UV B radiation induced pigments and biochemical contents in C. dwarakensis and C.tomentosum. In C. dwarakensis the maximum increase to the level of 177% of total chlorophyll, 151% of chlorophyll a, 221% in chlorophyll b , 15% of protein and 115% of carbohydrate contents was observed while in C.tomentosum, maximum increase to the level of 217% of total chlorophyll, 186% of chlorophyll a, 251% in chlorophyll b , 120% of protein and 1365% of carbohydrate contents was observed. The increase in the level of pigments and biochemical contents in C.dwarkenses and C.tomentosum is due to presence of these algae at intertidal region which may exhibit high tolerance to UV-B radiation. In addition to the position of the algae to the shore, presence of screening substances Mycosporine like aminoacid (MAA) also mitigate the effect of UV radiation.

Page No: 07-13
Abstract: In this project, two-function monomer of bisphenol A-glycidyl (BIS-GMA) was synthesized using diglycidyl ether bisphenolA epoxy resin (DGEBA) and methacrylic acid in the presence of a suitable Antago nistic activity of six species of Trichoderma viz., Trichoderma viride (S), Trichoderma viride (M), Trichoderma viride (C), Trichoderma harzianum (S) Trichoderma harzianum (M) and Trichoderma harzianum (C) against Fusarium pallidoroseum (Cooke) Sacc inflicting wilt of chilli was studied under both in vitro and in vivo conditions. Under in vitro conditions maximum inhibition of F. pallidoroseum was recorded by T. viride(S) (60.53%) followed by T. harzianum (S) (47.37%) while T. harzianum (M) (27.80%) proved least effective in inhibiting mycelial growth. In experimental chilli field with history of wilt incidence evaluation of six species of Trichoderma against F. pallidoroseum of chilli was conducted by dipping seedlings separately in spore suspension of (106 spores ml-1) of test biocontrol agents prior to transplanting. T. viride (S) and T. harzianum (S) were most promising followed by T. viride (C) and T. viride (M). All the bio-inoculants delayed mortality until fruit formation stage, increased plant stand and reduced significantly wilt incidence.

Keyword: Durian, optimization,microwave-vacuum, drying process
Page No: 14-22
Abstract: Durian (Durio Zibethinus) is a value fruit which contents high amount of nutrition, special flavor and is very good for heath. In this study, the microwave-vacuum drying process was used to determine the factors influencing the durian's quality in manufacturing. The multi-objective optimization method determined the technology mode of drying durian. Under these conditions which were the size of durian of 16 mm, the pressure of 25.47kPa, the drying time of 16.45 minutes, the final product achieved to the best quality which contented the highest level of vitamin C of 94.5%, the moisture of 4.7%, and the organoleptic valueof 18.25. The final result istotally compatible with the experiments and meet the requirements to apply into industrial manufacture of microwave-vacuum drying durians. Durian after drying has yellow color, crispiness, aroma, sweetness and special flavor. Keywords: Durian, optimization,microwave-vacuum, drying process Download PDF


Title: PRELIMINARY INVESTIGATION OF PERTINENCE OF CITATIONS IN INTRODUCTION SECTION OF PUBLISHED EMPIRICAL ARTICLES
Author: Adedayo, A. V.
Keyword: Content Analysis; Content pertinence; Performance evaluation; Impact Factor; Novelty; Citation analysis
Page No: 23-34
Abstract: The paper presents a study on analysis of citations made in the introduction section of articles that report empirical research. The attempt is to provide preliminary study towards validation of an e arlier proposition that significant amount of citations made in the introduction sections cannot positively count in the analysis to evaluate performance of scientific publications. In this present paper, citations made in the introduction sections in six different scientific publications were analyzed. A scientific journal was selected from each continent, and their first four articles published in 2014 were analyzed. Only articles that report empirical researches were analyzed. Overall, the study showed that over 80% of citations made in the introduction sections may not be applicable in the computation of effective impact of publications.

Abstract: The intake of food and control of blood glucose levels are very important in diabetic patients. To find out a potential component from seaweed, with anti-hyperglycemic effects, methanolic extract of a red seaweed Gracilaria dura , which contains complex mixtures of various types of bioactive compounds, which are having the hypoglycaemic effect was evaluated in alloxan-induced diabetic rats by using two different doses (200 and 400 mg kg-1 body weight). Blood glucose, glycosylated haemoglobin, haemoglobin, serum lipids of total cholesterol, triglyceride, high-density lipoprotein cholesterol (HDL-C), phospholipids, low density lipoprotein (LDL) and plasma insulin were examined in control and seaweed extract treated experimental rats. The aqueous extract was orally administered for 28 days. The results showed that the aqueous extract of Gracilaria dura significantly (p<0.05) reduced blood glucose level and restored the glycosylated haemoglobin and plasma insulin. These results demonstrate that Gracilaria dura could be useful in the development of anti-diabetic drugs.
