Vegetative performances, chemical composition and feeding value of soybean under impact of water deficit and spider mites

A pot experiment was conducted to investigate the vegetative performances, chemical composition and feeding value of soybean under impact of water deficit and spider mites as well as the possibility to their overcome through imidacloprid treatment. The development of aboveground mass, root mass and biochemical composition of soybeans were influenced by the water deficit and mites, but the sensitivity of these parameters to the action and interaction of these stress factors was different.

Performance evaluation of sweet sorghum lines for bio-ethanol and grains under pangasinan condition (3 trials)

The general objective of the study is to conduct evaluation trial of five (5) sweet sorghum lines under Pangasinan condition. Specifically, it aims to determine their agronomic characteristics and identify and recommend varieties that are suitable for ethanol production. This paper highlighted the results of the three (3) trials conducted from October 2007 to February 2009.

Relationships between relative growth rate, leaf nitrogen and leaf phosphorus in 17 herbaceous species of tropical dry deciduous forest of vindhyan highlands

The present study analyses relationship between relative growth rates (RGR), leaf nitrogen and leaf phosphorus. A range of leaf attributes was measured for 17 herbaceous species in four contrasting habitats fortnightly from   July to September (2006-2007). All herbaceous vegetation in 5 randomly located plots within each of four sites was clipped at ground level and analyzed fortnightly during the study period. RGR shows positive relationship with leaf nitrogen and leaf nitrogen.

Study the distribution of zooplankton population in the estuarine environment of manakudy

The present study was carried out in Manakudy estuary over a period of one year  May 2014 - April  2015. The collection was made on every month in the morning 7-9 a.m at regular intervals from the selected six stations. In each station, three spots were randomly fixed. Identified zooplankton species are grouped into Copepod, Rotifer, Cladocera, and Protozoa. The total number of 25 species were reported. Among these, 12 species belonged to Copepod, 5 species belonged to Rotifer, 2 species belonged to Cladocera and 6 species belonged to Protozoa. Copepod was found to be the dominant.

Perovskite solar cells: a quantum leap in solar research

Organic–inorganic metal halide perovskites are recently proved to be suitable candidates for application in solar cells. Devices made of perovskite show efficiencies from 3.8% in 2009 to National Renewable Energy Laboratory (NREL) certified efficiency of 22.1% in 2016 making this the fastest-advancing solar technology to date. CH3NH3PbI3 and CH3NH3PbI3-xClx are currently the front-and-center materials for high efficiency perovskite solar cell.

A comparative studies of two silkworm species in raigarh district for high quality yield

The sericulture industry is very unique and popular for its high valued textile fiber, agricultural outputs including, cocoons and cottage based labor intensive and for the production of high quality textiles. An attempt has been made to formulate a strategic model to recognizethe potential strength and challenges of sericulture in Raigarh district at Chhattisgarh state. We report results of the comparative studies relating to the silk production and productivity at Raigarh district from the silkworm species Antheraea mylitta and Bombyx mori.

Ecological restoration of arid land: a pilot approach in great Rann of Kachchh, Kachchh District, Gujarat, India

The Greater Rann of Kachchh (GRK) is a marshy and highly saline area characterized by flat terrain, harsh climate and ecologically fragile due to very low soil moisture and high soil salinity.  Therefore, an attempt was made on a pilot scale to reclaim the Rann and accelerate the natural recovery process of two bets (upland area), namely, the Kuar and Mori bets. Some traditional techniques of land resource practices were applied for reclaiming the area in year 2001 and 2007.

Identification of the composition of growth hormones in the tuber of dioscoreaalata

The identification of the growth hormones in the D. alata’stuber was conducted to investigate the composition (mg/l) of auxin, gibberellin and cytokinin in the three sectional parts of the D. alata’stuber in order to understand the potential aspects of the other parts of the tuber to be used as the seed. The findings show that the head, middle and tail sections of the D. alata’stuber content at least one growth hormone with the concentration of averagely more than 2.5 mg/l. Auxin was found in all sections with a significant concentration of ~ 2.8 mg/l.

Worrying and real risk for human papilloma virus-induced cervix lesions in cameroonian women: insight in a socioeconomically disadvantaged Muslim region

Cervical cancer is a real public health problem in developing countries especially in socioeconomically disadvantaged populations which are often very difficult-to-reach by health programs and mistrustful about these. We therefore carried out a pilot hospital-based cross-sectional study in the far north region, one of the poorest regions of Cameroon. This aimed at determining the prevalence of cervical pre-malignant and malignant lesions and of some main risk-increasing factors. Socio-demographical and risk factors for cervical abnormalities were documented.

Elastic and elasto-plastic finite element analysis of a tension test specimen with and without voids

Finite Element Analysis (FEA) is an important engineering tool used to assist in approximating and verifying how a component will react under various external and internal loading conditions. The purpose of this master of engineering project is to investigate and analyze fully elastic and elastic-plastic deformation of a High Strength Steel (HSS) tensile test specimen in FEA ANSYS under various conditions. In general, material selection is a key component to engineering analysis.
