Abstract: The solid waste management remains an outstanding problem to authorities and threat to health status and environmental quality. This is because the landfilling is the only alternative for getting rid of huge solid waste generated in Kano metropolis. This study tried to evaluate biodegradable components from the waste generated by households in parts of Kano metropolis. Stratified random sampling technique of data collection was used. The households were segregated into four socioeconomic levels (8 density units), where the solid waste was collected sorted and weighed from each of 78 households of the density units for a complete 30 days............

KeyWords: Solidwaste, biodegradable waste, solid waste management, landfilling, sorting, segregation, greenhouse gases, global warming, climate change, global warming potential

Abstract: The primitive e-waste recycling techniques along with industrial activities are among the most destructive activities in Moradabad, threatening the health, polluting the air and water and harming the land. The variations in air quality in terms of respirable dust i.e. PM10 and their heavy metal content around e-waste burning and industrial area were evaluated over the period of April 2015- September 2015 at five sites during different seasons i.e. summer and monsoon. Metals concentrations of PM10 were analyzed using ICP-OES. Highest concentrations of PM10 were recorded in summer and lower in monsoon at all the study sites. Mean concentration of PM10 and heavy metals was found highest at industrial sites and e-waste burning site than residential sites............

Abstract: ARIMA modelling has become a key tool of analysing climatic variables. To forecast rainfall of a particular region adequately time series ARIMA model may help the farmer as well as water management authority indispensably. For our study purpose, we take data from Bangladesh Meteorological Department (BMD) of Faridpur region for the period January1983 to December 2014. From our analysis ARIMA(0,0,0)(2,0,2)12 model was found that's why this developed model were used for forecasting monthly Precipitation for next three years to take proper decision of water development management authority...........

Abstract: Experiment was conducted at the Teaching and Research Farm of Ambrose Alli University, Ekpoma in Nigeria to evaluate the effects of some effluents on soil chemical properties in maize cultivated soil. Treatments consisted of poultry, abattoir, cassava mill, oil palm mill and fish pond effluents with control. Effluents were uniformly applied to the soil surface at the rate of 5 t/ha a month before planting to allow for equilibration. Results showed that effluents increased pH from 5.47 to 5.62, organic carbon 10.10 g/kg to 12.20 g/kg; total N 0.50g/kg to 1.00 g/kg; available P 2.90mg/kg to 6.76 mg/kg; exchangeable Ca 2.28cmol/kg to 4.25 cmol/kg;............

Abstract: Gold mining is the global largest source of mercury pollution. In Indonesia, Wonogiri Regency, Central Java, mining workers in one of the traditional mining area use mercury for amalgamation of gold. A preliminary survey showed that about 57,5% of the workers traditional gold miners had a high blood mercury levels. The aim of research was to confirm that coconut water can prevent oxidative stress resulting from mercury exposure. This was an experimental research with a randomized pre and post test control group design. The treatment group was given tender coconut water (450 ml/ day for 30 days) and the control was given water. The 38 mining workers recruited randomly were given a questionnaire and were subjected to MDA level using Elisa method. The Data were analyzed using Mann Whitney test for abnormal distribution.............

Abstract: A quantitative assessment of Soil productivity has been done for tobacco plantation area in Lombok. The output of this assessment is called soil productivity index (SPI) which is a percentage of crop yields obtained under actual soil and climatic conditions in the field, relative to potential yield under ideal condition. The aim of this study was to develop a robust soil productivity index for rice, tobacco and soybean. Data required were soil properties, namely: physical properties, chemical and fertility..............

Abstract: The effect of domestic processing method on the proximate and anti-nutritional content of the leaf of Cnidoscolus aconitifolius was properly investigated using standard method. The proximate result shows that there were high content of ash, protein, fibre, and carbohydrate, with ranges of 2.20±0.6-2.67±0.5, 2.91±3.0-3.60±1.0, 1.43±0.1-2.50±0.1 and 8.79±2.6-9.65±1.6 respectively and fat between 78.33±0.10-86.30±0.28. Little concentrations of phytate, oxalate and tannin, with ranges of 0.22 ± 0.01% - 0.35% ± 0.01%, 0.14 ± 0.02% - 0.41 ± 0.09% and 1.64 ± 0.03% - 1.94 ± 0.02% were observed. The concentrations of these anti-nutrients were controlled by the treatment process..............

Abstract: Banana peels are lignocellulosic agricultural waste that has the potential to produce bioethanol as a renewable form of energy. Pretreatment and hydrolysis of lignocellulosic biomass are crucial steps in bioethanol production. Our study determined the efficiency of three pretreatment techniques namely water, alkaline, and acidic pretreatments on the production of bioethanol. We applied the same hydrolysis technique using H2SO4 to all the pretreatment techniques. Our results showed highest reducing sugar concentrations when banana peels were pretreated with acid; pretreatment using water alone gave the lowest reducing sugar concentrations..............

Abstract:The volatile oils of Rosemarinus Officinalis (rosemary) and Thymus citriodorus (Lemon thyme) at different concentration (0.1, 0.25, and 0.5) % were used to examine their preservation impacts on raw chicken.). Chicken pieces were immersed in ethanolic solutions (10 %) of the volatile oils of rosemary and lemon thyme for 30 minutes stored in (30oC) and in a fridge (4oC.After the first day, control samples were found completely putrefied, whereas samples treated with VOs (0.25 and 0.5 %) were found with acceptable organoleptic attributes and significant microbial prohibition for five days at (30oC) and for 10 days in the fridge (4oC). It can be concluded that beside their desirable flavours, the herbal VOs used can be considered as a natural preservative to prolong shelf life of raw poultry and this could have an economical potential on raw chickens at industrial level.

Abstract: This study aimed to assess the hydrobiological characteristics of Layawan River based on the standards set by the Department of Environment and Natural Resources (DENR) on the physico-chemical parameters such as phosphates, total suspended solids, pH and temperature, as well as total coliform.Descriptive normative method of gathering data was done with the aid of chemical, biological and physical laboratory analyses. Temperature and pH were measured directly on the field. Water samples for the other physico-chemical parameters and total coliform count were brought to the laboratory for analysis. Inferential statistics such as T-test and Chi-Square (χ2) test were applied to determine the significant differences of the values obtain between seasons.Results of the study revealed that physico-chemical parameters and total coliform were within the DENR standard categorizing Layawan River as Class A water regardless of season.............
