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.

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.

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.

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.

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.

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.

The aim of the research was to determine the effects of Anhydrous ammonia application on yield and yield components of sunflower. Field experiment was conducted in Tekirdag at Trakya Region, Turkey during 2014 and 2015. Three different methods was planned. Anhydrous ammonia application (M1), the traditional condition (M2) and the control (M3). Anhydrous ammonia application was made once before the sowing period. At the M2 is the method used by local farmers. No nitrogen fertilization was at the M3 method.

In this paper we present a concrete method to estimate the moments of time of ruin, surplus immediately before the ruin and deficit at ruin under two way renewal process. Gerber–Shiu discounted penalty function are used to estimate the same. Laplace transform is taken into account while calculating the moment. Furthermore, Lindley distribution is being assumed as the distribution of the claim amount .This approach allows for the experimentation of various distribution forms among the eventual random variables.

Data transfer from one server to another needs a great ontology process in which data from one server to another gets migrated with a protocol service in which three layers are minimum required. In this work, focus on migrating the particular application data. Cloud creates a series of mechanical, architectural and legal challenge that the State of the Art attempts to address. Arrange such efforts into a set of migration scenarios and connect them with a list of reusable results for the application data migration in the form of patterns.

In this study, we apply Grey System Theory-GM (1, 1) based on the statistics provided by the Vietnam dairy Products Joint-Stock Company (Vinamilk) from 2009 to 2016 and make prediction values for two years, i.e., 2017 and 2018. The results which help enterprises to figure out the target in the near future are shown with low tolerance proven by Mean Absolute Percent Error (MAPE).
