Abstract: The most common accidents in industrial laundries involve chemical exposure, sharp objects left in soiled linen, slips from wet floors, exposure to pathogens in contaminated linen, among others. This study sought to provide information on the common health and safety complaints among laundry workers in tertiary and secondary health facilities, as this would prove useful in order to establish appropriate interventions. It was a comparative cross-sectional study, conducted in six hospitals with a laundry department in Benin-city, composed of one available tertiary healthcare facility and five secondary healthcare facilities. Questionnaires were administered to the workers to obtain data on their work-related injuries and diseases. Also, body mapping exercise was conducted to obtain workers......

Abstract: A greater production of renewable energy is required based on the imminent depletion of fossil fuels and the environmental problems arising from their misuse. Biomass is in a privileged position due to numerous advantages such as decentralization, the potential of using agro-industrial waste, zero balance of CO2 and the possibility of creating jobs in rural areas. Gasification processes of olive residue from the production of olive oil using air and steam at different temperature were carried out. The composition of the gas produced and its heating value are reported. Based on the results the predominant chemical route and optimal gasification conditions were identified. A feasibility study focused on the design of a pilot scale gasification plant was performed.

Abstract: Currently, Viet Nam is one of the developing countries which have fastest economic growth rate in the world. Contribution to the mariculous development, there is agriculture in general, and mushroom cultivation in part. However, along with the development of the mushroom cultivation, there are some environmental problems generated and the status in the Dinh Quan district, Dong Nai province is not exceptional. In order to understanding the environmental actualities in the mushroom area of the Dinh Quan district and hence proposing apprpriate measures to improve environmental protection effectiveness in the region, there need to have a systematic and scientific research addressing the issues, and this is the main reasons for implementation of the research. During the research implementation, various methods such as: collection of data and information; people's survey............

Abstract: The purpose of the study was to assess some physicochemical parameters of soil and the heavy metal concentrations in soil and vegetables along the bank of Mpape River in FCT, Abuja. The study was carried out in dry season between 2016 and 2017. Soil and vegetables samples were collected simultaneously from three irrigated farm sites. Heavy metal levels were quantified using Atomic Absorption Spectrophotometer (AAS). Other parameters were determined using standard methods. The levels of physicochemical characteristics in soil and the heavy metals in soil and vegetables varied significantly according to sites without adhering to any significant trend. Soil pH (5.62±0.72) was slightly............

Abstract: Microorganisms play an important role in food industry. As already discussed in the earlier article Contributions of Microbiology in Food Industry, they are used in production of various food products, and are also responsible for food spoilage thereby causing intoxication and diseases.Microbial contamination of food products takes places usually on the way from the field to the processing plant, or during processing, storage, transport and distribution or before consumption. The microorganisms that cause food spoilage and also find the maximum exploitation in production of food and food products are mainly bacteria, molds and yeasts

Abstract: MMost of our universities have no computer laboratories for practicing parallel programming. In this paper, we will show how students can get benefits from graphic processing unit (GPU) devices by using them as P3 in solving parallel programming assignments. The main advantage of GPU computing is that it provides cheap parallel processing environments for those who need to solve Single Program Multiple Data (SPMD) problems. In this paper, Single Host Single Device (SHSD) is proposed to be used for solving many different problems taught in parallel programming course...............

Abstract: Fire hazard incident is very much common phenomenon in Bangladesh especially at densely populated Dhaka city. Every year many people died due to the fire hazards. They lost their lives, wealth, properties and suffer from burn injury for a long time. Being the hub of all economic activities this city compels people to live here and construct High rise buildings, Semi-structured buildings and temporary shades in slums and squatters and also build Ready-made-Garments or Industries, Shopping Malls, Educational Institutions and Hospitals or Medical Centers. We find that in this City, these structures/buildings are closely spaced, in most cases the owners or authorities do not follow the building code, most of the dwellers and owners do not have better awareness and minimum fire management knowledge and practice. In most of the cases, they cannot understand the intensity and severity of devastating fire hazards and identifying the reasons and taking effective mitigation measures are not prevalence................

Abstract: Potted plant experiments in petroleum-spiked soils were carried out using the wetland plant, Commelina benghalensis of the Niger Delta Region, Nigeria. Petroleum degrading endophyte Providencia rettgeri, from an aquatic plant, Sacciolepsis africana, was inoculated in treatments using the root inoculation method. The treatments include sterilized and unsterilized soil, with or without the addition of nutrient (NPK). Results obtained showed a gradual decrease in plant growth and reduction in residual Total Petroleum Hydrocarbon with the endophyte-nutrient-unsterile soil treatment (CUSENPK) having the least with 48.77% of the oil degraded; and following in decreasing order................

Abstract: Pesticides are major sources of environmental pollutants utilized to control or eradicate pests negatively impacting on man agricultural resources. Amid the varied classes of pesticides, Paraquat di-chloride, an organochloride is widely deployed against varieties of agricultural and domestic pest with potential consequences. This study examined the impact of Paraquat (1,1-dimethyl 4, 4-bipyridiniumdicholoride) on the gills and liver of Clarias gariepinus. In the acute studies, fish were allocated into five groups and exposed to 50, 100, 150,250 and 250 mg L of Paraquat for 96 h. In chronic exposure, fish were distributed into 2 groups and exposed to 1/10th and 1/100th 96 Hr LC50 value of (128.03 mg L) of Paraquat for 30 days. Liver and gills were harvested and evaluated for antioxidant parameters and histopathology respectively. There was no significant induction (P > 0.05) in the activity of SOD activity in exposed organisms while CAT enzyme activity was significantly (P < 0.05) induced in.............

Abstract: As water is vital for the continuous survival of life on the planet earth, hand-dug wells are the cheapest alternatives to pipe born or borehole water in developing countries. This study was aimed at calculating and comparing the Water Quality Indices (WQI) of water from hand-dug wells cited near septic tanks in order to determine its suitability for drinking purposes using the Weighted Arithmetic Water Quality Index (WAWQI) and Canadian Council of Ministers of the Environment (CCME) Water Quality Index (CCME WQI). The calculation using the WAWQI revealed Well A (81) = "Very poor", Well B (58) = "Poor", Well C (63) = "Poor", and Well D (95) = "Very Poor.............
