Some opportunistic observations on the diversity of hawk moths have been done from June 2015 to May 2016 in North Malabar region of kerala. We have identified10 genera and 23species of Hawk moth belongs to3 subfamilies of Sphingidae. Of these 20species of hawk moths are new records to Malabar region. From our study we come to a conclusion that Malabar region is a suitable habitat for these highly sensitive families of moths. The paper gives details regarding Collection methodology, Diversity indices of each three subfamilies of sphingidae, effect of lunar periodicity in the diversity of the moth species and seasonal fluctuations.

Let be a simple graph. A set is an Edge-Vertex dominating set of G (or simply an ev-Dominating set), if for all vertices , there exists an edge such that dominates . Let be the Star graph and let denote the family of all Edge-Vertex dominating sets of with cardinality . Let , be the number of Edge-Vertex dominating sets of with cardinality . In this paper, we study the concept of Edge-Vertex domination polynomials of Star graph . The Edge-Vertex Domination polynomial of is . We obtain some properties of and its coefficients. Also, we calculate the recursive formula to derive the Edge-Vertex Domination polynomials of Star graph.

The present study explores the effectiveness of Graphical Organizer (GO)Teaching Model on Student’s Learning Achievement in General Science at Elementary School Level. Graphic Organizer Teaching Model helps teachers to make their content understandable for their students. The objectives of the present study were to asses the effect of GO Teaching Model on students’ learning and explore the understanding of student. It was an experimentally study. The experiment was conducted at an Elementary School. Pre-test posttest control group design was adopted for conducting the experiment for the study. Difference in achievement of students (in control and experimental group) in General Science was checked through comparison of their performance in Post-test. Data analysis revealed that students of experiment group who were taught through GO teaching got more marks than students in control group. Findings depicted that GO Model proved an effective instructional strategy. The result reported that students learning achievement was improved through the use of GO in General Science. It was recommended that teachers may be trained in how to design and use GO in teaching. The findings of the study have implication for teachers, curriculum developer’s educationists and researchers.

The Au and thiol substituted 2,5-divinylthiophene molecule has been studied for the zero field and various levels of applied external electric fields (EFs) using quantum chemical calculations coupled with AIM theory. The variation in geometrical parameters due to the various external EFs and the corresponding transport properties of the molecule has been analyzed. The variation in MPA and NPA charges, the reduction of HOMO-LUMO gap (from 2.34 to 1.08 eV) and the increase of electric dipole moment (from 0.98 to 13.21 D) with the increase of external EFs (from zero to 0.26 VÅ-1) of the molecule reveals that using thiol as linker and Au as electrodes, 2,5-divinylthiophene molecule can be act as an efficient molecular nanowire.

In the present study, the lead phytoaccumulation and its effects on the growth and antioxidant status were determined in Trigonella foenum graceum. The phytotoxicity was studied in the germinating seeds under the exposure to increasing concentrations of lead acetate (25, 50, 100, 200 µM). Although there was a decrease in the germination percentage of the seeds to increasing concentrations, normal growth was observed after germination. The plant was capable of tolerating various concentrations of lead revealed by its vigorous growth after the 16th day of treatment. Pb caused significant reductions in the chlorophyll content, protein content and induced changes in the antioxidant enzymes .Pb decreased the activity of SOD and Catalase while the activity of GPx and LPO were induced significantly after Pb exposure. The plant expressed higher tolerance to Pb which is mainly attributed by its normal growth and physiology.

The research was conducted to find out the effect of implementation of HACCP in a baking industry. The quality attributes such as microbial count and compositional analysis were done to find out the positive effect. High energy fortified biscuits was prepared as influenced by different levels of soy flour protein and wheat flour gluten content of the biscuit recipes in a food industry before food safety implementation. Packaging study was also conducted by high density polyethylene up to 90 days of storage showing moisture content just above Bangladesh Standards and Testing Institute (BSTI) requirement at 90 days for the samples S1, S2 and S3. Moisture%, Protein %, fat %, sucrose % and iron content remained acceptable considering BSTI requirements. Sample S1 containing highest soy flour protein and wheat flour gluten estimated highest protein %, fat% and iron content compared to sample S¬2 and S3. Microbial qualities of biscuits found acceptable at initial storage regardless of microbial quality of raw materials. Sensory qualities of biscuits were also evaluated which showed the sample S3 , treated with lowest amount of soy flour protein and wheat flour gluten, was the most preferred biscuit with respect to all the quality attributes. Though the high energy fortified biscuit has compact source of energy, packaging condition was not sufficient to hold moisture content as BSTI standard level during 90 days of storage.

The experiment was conducted to study the effect of varying plant population of two sorghum cultivars on growth and yield at research area Gash Delta Eastern Sudan, during 2014/15 and 2016/17) seasons. The RCBD design used for split-split plot trail. The treatments include two cultivars (Tabat andAklamoi) and three planting densities (spacing within the row of 30, 45 and 60 cm between holes and the number of seeds per hole factor with 3, 4, 5, 6, 7, and 10 seeds per hole).The obtained results revealed that, the two tested sorghum cultivars particularly in the second seasons showed highly significant differences in stem girth, leave area index, panicle/m2, seeds /panicle, 100-seed weight and grain yield/ha. Aklamoi was better than Tabat in panicle/m2, 100-seed weight while, Tabat exceeded Aklamoi in stem girth, leaf area and grain yield particularly at plant population 208333 plant/ha which was achieved from 30cm inter-row spacing with five plants/hole in the first Season. The obtained grand mean of grain yield of Sorghum and the observations across the two experimental seasons indicate the high adaptability, the highest growth and the highest grain yield of Sorghum under the conditions of the Gash Delta. Early maturity of sorghum cultivars is more important to cultivate under shortage flooding seasons.
