Observations on relative abundance of various species of Apis (A. mellifera, A. cerana, A.florea and A. dorsata) on parental lines of Brassica napus in hybrid seed production plots revealed that A.mellifera was the most abundant visitor thus excellent pollinator. Bee visitation was significantly more in case of experimental plots with male & female row ratio 2:4 followed by 1:4 and 1:8. So hybrid seed production plots with male to female row ratio 2:4 with A.mellifera beekeeping is suggested. Cytoplasmacally male sterile flowers showed lesser bee abundance than that on flowers of restorer line, which was a limiting factor, for hybrid seed production. Further research work is required to select or develop CMS and R lines, which must be equally attractive to bees. The finding of the study will enhance the existing knowledge regarding honeybee management for pollination, hybrid seed production, pollinating efficiency of different types of honeybees and apiculture in general.

The nexus between water, energy and food (WEF) is the focus of growing concerns on the availability of vital resources derived from these intertwined systems, and how to manage the nexus resources to respond to the challenges posed by future human demands, aggravated by the perspective of climate change. This paper uses the recent Paris Climate Agreement as a WEF nexus case study, in which we assess the near-term and medium-term implications of the Paris pledges on the WEF nexus in the region of Latin America and the Caribbean (LAC). For this purpose, we employ the Global Change Assessment Model (GCAM), a state-of-the-art integrated assessment model of human and natural...........

A crucial public health problem in developing country like Bangladesh is resistance of antibiotics to different types of bacteria and the rates of these bacterial resistances are changing for various antibiotic therapy. Our aim was to assess the susceptible pattern of Cefixime of 3rd generation cephalosporin antibiotic against uropathogens. A total of 12943 urine samples were collected in 2016 (Jan-Dec) and out of which 1236 (9.55%) were bacteriologically positive. Among the isolated uropathogens, 95.1% were gram negative and 4.9% gram positive organism. Male were found more prone to get UTI under 10 years and between 51-90 years of age and females were more affected in 10 to 50 years and over 90 years of age group. E.coli was the most prevalent (83.9%) isolate followed by Klebsiella spp (6.7%), Staphylococcus aureus.......

Industry produces large quantities of highly polluted wastewater containing toxic substances, organic and inor-ganic compounds such as: heavy metals, pesticides, phenols and derivatives thereof, aromatic and aliphatic hydrocarbons, halogenated compounds, etc., which are generally resistant to destruction by biological treatment methods. Food industry uses large amounts of water for many different purposes including cooling and cleaning, as a raw material, as sanitary water for food processing, for transportation, cooking and dissolving, as auxiliary water etc. The Nutrition Processing Industry is committed to improve their environmental performance and to meeting or exceeding the requirements of all applicable environmental laws and regulation........

This paper presents Structural Analysis of a 6-DOF Robot Spray Coating Manipulator for automobile application using NX-CAD and ANSYS APDLsoftware. In automobile most products manufacture from metallic materials require some form of painted finish before delivery to the customer, the technology for applying these finishes varies in complexity from simple manual methods to highly sophisticated automatic techniques.When accomplished manually, the result in many health hazards to the human operator these include fumes and mist in the air, noise from the nozzle, fire hazards and potential cancer hazards. The feature of many robot spraycoating applications is that the manipulator must be designed and analysis to process a variety of part styles, each with its unique configuration........

The present study was assumed to evaluate the physicochemical parameters of the water and to determine heavy metal concentrations in water of Rupsha River, Khulna, Bangladesh. The water quality parameters were measured for samples collected from twenty-two (22) sampling stations throughout the year 2016-2017. Obtained results were compared with the standard values of "Bangladesh Standards and Testing Institution (BSTI)"and "World Health Organization (WHO)" value as well as experimental results were analysed statistically with MS-Excel and SPSS software and Pearson Correlation Program.......

This study aims to examine and analyze empirically the effects of relationship marketing on satisfaction and loyalty of students at the High School of Economic Science Enam Enam Kendari. This research is intended to explain the position of the explanatory variables that were examined as well as the relationship and effects of one variable with another variable. The results showed that (1) Relationship marketing has directly significant and positive impacts on student satisfaction and loyalty. Increased relationship marketing and a real positive direction increase student satisfaction and loyalty of students at the High School of Economics Science Enam Enam Kendari, (2) there are direct student satisfaction and not significant positive effect on student loyalty. It means that the satisfaction students can directly not form loyalty of students.

For the horizons VII‒VIIa of the Productive Series (the Lower Pliocene) of the Garadag gas-condensate field (Azerbaijan) used for underground gas storage (UGS) the reservoir rock properties and gas saturation models are given.The models use the software package 'ROXAR' (IrapRMS). The purpose is to identify spatial changes of the rock properties of the productive stratum. The fluid saturation model of productive horizons clearly demonstrates the progress of water infiltration into the gas reservoir with the tendency towards fragmentation into isolated pillars due to the mosaic nature of the reservoir rock properties. The factors determined can enhance the efficiency of further exploitation of the Garadag UGS.
