This study was conducted to assess demography and dynamics of mountain nyala (Tragelaphus buxtoni) in relation to habitats/vegetation, slope, seasons, altitude. The data were collected in 1984 eight years before population crash of T. buxtoni in 1991 in Bale Mountains National Park. Sample total count method was used to survey the population in three sites where the species known to be abundant in the northern part of the Park.

It is important to identify the genetic diversity amongst sugarcane genetic resources for cultivar development and evaluation of sugarcane varieties. The genetic diversities of 125 sugarcane varieties including 117 varieties (lines) developed in Guangxi (China) and 8 others were studied using 10 SSR markers. The results showed amplification of total 110 bands ranged from 90 to 350 bp in size. The number of bands per locus ranged from 7-14, when scoring was restricted to strongly amplified fragments, and averaged 10.5 polymorphic bands per locus.

Mining in the Asutifi district began in 2003 when Newmont Gold mining (GH) Limited started mining gold. Since then, the company’s operations have continued to expand covering large areas of land that falls in their concessions. This study analyses the mining operations of Newmont in the Asutifi district and how their operations are affecting the livelihood of the residents of the district. Using a quantitative approach, self-administered structured questionnaires were distributed to 150 respondents and responses analysed.

Electricity is the major share of total global energy requirement, which is expected to be exponentially growing. As the demand grows steadily, not only will the supply become inadequate, it’s transmission and distribution will become inefficient and wasteful. The existing grid infrastructure was not basically designed for today’s pace of power transfer. It has not been updated and upgraded in accordance to the pace of increases in power and itsdelivery. As the power grid network is already a complex structure, the dynamics of this structure becomes more crucial due to overloading.

The experiment was conducted in the five years old mulberry germplasms maintained at Sericulture Department. The study was conducted in all three seasons of the year 2010-2011 viz., pre monsoon (March-June), monsoon (July-Oct) and post–monsoon (November– February). The two sucking pests were selected for the study namely Pink mealy bug, Meconellicoccus hirsutus Green and Thrips, Pseudodendro thrips mori (NIWA). Score Index was followed to categorize the genotypes for various level of pest infestation. During pre-monsoon season (March – June), infestation of sucking pest, Pink mealy bug, M.

Objective: To evaluate the antibacterial activity of two saltpan microalgae Amphora sp and Oscillatoria sp against post operative pathogens Methods: Samples of microalgae were collected from the puthalam solar saltpan of Kanyakumari district. Two microalgae Amphora sp and Oscillatoria sp were identified and isolated by serial dilution method. Biomass was produced by culturing the isolated strains in one litre of Walne’s medium. The activity was assessed by using ethanol and petroleum ether solvents.

Rural society is the primitive society of man. India is well-known in the world because of Indian rural culture and society. Farmers are the backbone of country.65% Indian economy is depending on agriculture. Therefore really if we want to develop India, there is a need to develop the rural society. Today Indian farmers are having so many social, familiar and economical problems. Farmer’s suicide is crucial and serious problem in current scenario. Some states in India having the large number of farmer’s suicide cases.

This work was developed in the semiarid region of São José da Tapera, in the state of Alagoas, Brazil, in order to assess the quality of goat milk in two communities: Settlement Mocambo and Settlement Selma Bandeira. Milk were analyzed in 74 goats that survive under extensive management in the Caatinga. All animals were Brown Alpine breed. Microbiological analyzes were performed at the Microbiology Laboratory of the Veterinary School of the Federal University of Alagoas.

Many agriculturally important traits such as yield, quality and some form of disease resistance are controlled by many genes (poly genes) and are known as quantitative traits. Identification of the genomic region containing few or more genes controlling these complex traits is a basic idea of QTL mapping. The large number of QTL mapping studies for diverse crop species has provided an abundance of DNA marker-trait associations. The information obtained on the QTL analysis can be utilized for the crop improvement through marker aided selection and molecular breeding.

The present investigation was concluded to evaluate the lethality of cypermetrhin on common carp, Cyprinus carpio. The effect was assessed on the basis of 10,20 and 30 days exposure of its sublethal concentrations (1/5th (0.02 mg/L) and 1/10th (0.01mg/L) on some hematological parameters. Fish were sampled at 10, 20 and 30 days to test for blood analysis. There was most of the blood parameters measured such as hemoglobin (Hb), red blood cells (RBC), packed cell volume (PCV) and MCHC was significantly decreased (p< 0.05), but the WBC levels were significantly increased (p< 0.05).
