Abstract: Industrial wastewater contain certain chemical nutrients especially compounds of nitrogen and phosphorus, and heavy metals which if discarded without treatment can lead to eutrophication and related environmental issues that affect the recycling processes of bio system. Currently, many efficient procedures exist for removing these nutrients but they usually present drawbacks in terms of cost-effectiveness, complexity of operation, waste generation (sludge) and/or high energy consumption. In order to overcome these problems, this research work focused on treating industrial wastewaters by using microalgae technology. Microalgae was cultivated on the industrial wastewater which provide not only water medium but also source of necessary nutrients suitable for algal cultivation,..............

Abstract: The purpose of the study is to understand importance of responsible nuclear waste management and the laws necessary for its implementation. The study is focused on understanding of how uranium evolved as an important source for power generation as well as prerequisites of safe use of radioactive substances.Study additionally concentrates on the Indian scenario of Statuary laws essential for disposing the nuclear waste responsibly and genuinity of the environmental clearances granted to national power plants under EIA notification. The research concludes with recommendations to amend policy implementation of environment ministry.

Abstract: Three different samples of cheese were used to investigate the effect of freeze drying on the nutritional content of local cheese. Sample A was obtained from Bida in Niger state. While samples B and C are obtained from Suleja and Kontagora respectively all in Niger state. The results of the proximate analysis showed that sample A with initial moisture content of 0.62 has a calorific value (calculated from the amount of carbohydrate, protein and fat) of 557.01 Kcal/100g after freeze drying at a temperature of 25 oC and a chamber pressure of 2.7 N/m2for 5 hours. This is above the minimum recommended standard value of 465 Kcal/100g by Food and Agricultural Organization (FAO) and World Health Organization (WHO) for Milk and dairy products. The calcium content was 311 mg lower than the minimum standard value of 1000 mg by FAO and WHO................

Abstract: Background: It is well known that Listeria monocytogenes is a substantial foodborne pathogen that can boost in cooling temperature and causes serious human infections. Materials and methods: The study investigated 60 chilled pork byproducts purchased from Egyptian markets and PCR assayed for the presence of certain virulence genes answerable for the pathogenicity, besides the anti-listerial activity inquiry of probiotic bacteria. Results: eleven Listeria monocytogenes isolates (18.3%) were obtained and the survey exposed that 6 isolates harbored hly gene, 7 carried inlA gene, and 7 loaded prfA gene in incidence of 54.5, 63.6, and 63.6% respectively in which the three genes were identified in three isolates (27.3%). The isolates were sensitive to Lactobacillus acidophilus more than Lactobacillus plantarum even diluted to10.

Abstract: In an attempt to cover up the unappealing taste of the freshwater thin-lipped grey mullet (Liza ramada) and to produce a convenient agro-food product, cold smoking was applied to fish fillets followed by vacuum packaging. Based on biochemical, microbiological, and sensorial analysis, several indices were used to monitor the product quality over 60 days of refrigerated storage at 2 ±1°C. A different pattern of amine changes occurred following salting and smoking. Except for (his) and (spm); all others amines including cadaverine increased in cold smoked fillets throughout storage. The indices of atherogenicity (IA) and of thrombogenicity (IT) with values of 1.68 and 1.67 respectively, did not show a significant change during storage suggesting a stability of the fatty acids profile...............

Abstract: The purpose of this study was to investigate preparation of ice milk mixes by substituting oat milk and oatmeal or barley milk and milled barley instead of buffalo skim milk (BSM) and skim milk powder (SMP) at ratios 0 : 100 (C0), 25 : 75 (OC25 & BC25), 50 : 50 (OC50 & BC50), 75 : 25 (OC75 & BC75) and 100 : 0 (O100 & B100) and substituting their blend instead of BSM and SMP at ratio 75 : 25 (OBC75) and evaluation of frozen products physically, sensually, economically and nutritionally. The ice milk made from 100% BSM and SMP served as the control (C0). The results showed that replacement of non fat milk solids (MSNF) with grain oat and barley components increased pH and viscosity values and decreased the specific gravity (Sp.gr), weight per gallon (Wt/gal) and whipping ability of ice milk mixes...........

Abstract: Steady declining of soil productivity aggravated by diminishing per capita holdings of arable land poses a severe threat to sustainability of agricultural production and livelihoods for the majority ofthe farming population inbeed district. Farming mechanism and strategies in Beedn agriculture is mainly focus on technological transfer which put loose attention to local soil fertility managementpractices. Thus, aggregately, less production is being achieved. Hence, the only use of modern science in diverse agro-ecological zone of farming area and complex socio-economic conditions of the people has failed to ensure sustainable agriculture. Nowadays, across the world however, there is significant recognition of the role of Indigenous Knowledge (IK) in many development dimensions which is not exceptional to soil fertility management. However, in Beed the absence of effective linkage between IK and modern science.............

Abstract: This study was conducted to initially determined drinking water quality in Cagayan de Oro, Philippines. The objectives were to quantify selected physicochemical parameters among selected tap water samples on December, 2016-Feburary, 2017 in District 1 communities of the city. Analyses further included quantifying risk quotient and comparing findings to drinking water quality standard. Studied parameters were pH, temperature, dissolved oxygen (DO), total dissolved solids (TDS), salinity, conductivity, and turbidity using portable probe pre calibrated meters. Overall, determined concentrations passed reference standards for drinking water with sampling station and sampling period variation. Although no risk was determined on the studied parameters, it is however recommended to conduct further monitoring incorporating other water quality parameters.

Abstract: Though carbofuran has known to possess adverse effects in soil organisms including earthworms, little is known about the effects of carbofuran, either dirrectly or indirrectly, on the earthworm Pheretima javanica. This study aimed to investigate the effect of carbofuran at sublethal doses on the cocoons production and viability of Pheretima javanica worms. Six groups of earthworms, each consisted of four worms, were reared in plastic pots and fed on cow manure mixed with carbofuran as much as 0 mg (for control), 0.1mg , 0.2mg, 0.3mg, 0.4mg and 0.5mg repectively. Cocoons produced were hand sorted every two weeks for three months and presented as the number of cocoons...........
