Considering to Importance of Food Industries related to generate employment, more so than many other manufacturing sector and also it’s vital role in Iran’s economy. This paper examines the determinants of labour productivity in food industries of Iran over the 1995-2006 period. The study applied the Cobb–Douglas production function of industry. The results showed that total factor productivity is 17.8 percent. The determinants like education, skilled, specialist, capital per worker and wages have affected on productivity’s differences in Iranian food industries. The most important factor was employee’s specialization in this industry.

The antidiabetic drug pioglitazone is hydrophobic and having dissolution rate limited bioavailability. Several attempts were made to enhance its dissolution rate. In this investigation the two well known techniques viz., microcapsules and compression coating originally designed for sustained drug delivery were used for enhancing the dissolution rate of Pioglitazone. The polymer eudragit E100 was reported as a taste masking material for bitter drugs. However this research work is aimed to exploit eudragit E100 as dissolution enhancer by virtue of its acid solubility. The polymer was incorporated as a carrier for preparation of solid dispersion, coating material in microcapsules and compression coated tablets. The prepared formulations were evaluated for various parameters including the compatibility studies with IR spectra and drug dissolution studies. The drug Pioglitazone was found to be compatible with eudragit and dissolution rate was also increased in presence of the polymer. The dissolution rate was increased in presence of the polymer and dependent on the technique employed. High dissolution rate of Pioglitazone was observed from the tablets coated with the polymer eudragit E100.

The N2- fixing cyanobacteria are important agents in crop fields contributing to the primary productivity and nitrogen economy of the soil. In the present study, diversity and abundance of N2- fixing cyanobacterial population were investigated in the rice ecosystems of the Brahmaputra floodplain in response to the soil physico chemical properties in four different seasons. Altogether 51 species of N2- fixing cyanobacteria belonging to 15 genera under 7 families were recorded in two common rice cropping systems - double rice cultivation (RR) and rice rotated with mustard (RMR). Among the isolated genera, 10 were heterocystous and 6 were non heterocystous. The genera Anabaena (25%) and Nostoc (19%) comprised of the highest number of species followed by Calothrix (8%) and Phormidium (8%). Results of relative abundance also revealed the dominance of Anabaena and Nostoc in the rice ecosystems of the valley. Pearson’s correlation analysis showed significant correlation between population number of N2- fixing cyanobacteria and soil physico-chemical properties. Canonical component analysis (CCA) justified the seasonal pattern of population abundance along with the concomitant change of soil parameters like temperature, moisture, pH and available phosphate in the rice field soil of the valley.

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.
