Abstract: In this study the effect of sprouting time (0h, 24h, 48h, 72h, 96h and 120h) on the nutritional, and anti-nutritional properties of cowpea was investigated. Cowpea seeds were sprouted in the laboratory under room conditions (250C). The germinated seeds were removed, sun-dried, weighed and milled for proximate, minerals, functional and anti-nutritional factors analysis using standard methods. Sprouting resulted in increase in most of the nutrients except fat and carbohydrate which were reduced. The protein ranged from 20.16-34.05%, Ash 3.07-4.77%, fat 1.51-3.02%, fibre 4.14-5.08%, moisture 5.64-6.72% and carbohydrate 47.87-64.01%. The minerals (potassium, sodium, calcium, magnesium and phosphous) in the sprouts increased as the germination time increased. All the determined anti-nutrients (alkaloids, flavonoids and phytates) decreased with increase in germinating time. It can be concluded that sprouting improved the nutritional quality of the cowpea in terms of higher concentration of nutrients, and reduced antinutrients.

Abstract: The effects of boiling and fermentation on the chemical composition and functional properties of African locust bean flours were studied. The seeds were sorted, cleaned and processed into raw, boiled and fermented African locust bean flours. The flours produced were evaluated for proximate, vitamin and functional properties using standard analytical methods. The proximate composition of the samples showed that the flours had a range of moisture, 9.45-10.06%, crude protein, 21.24-22.62%, fat, 10.31-11.32%, ash, 3.00-4.19%, crude fibre, 3.25-3.84%, carbohydrate, 45.80-52.21% and energy, 378.59-388.83 KJ/100g, respectively. The vitamin composition of the flours showed that the vitamin A, ascorbic acid, vitamin E, thiamine, riboflavin and niacin contents of the samples varied between 3.26-4.91 mg/100g, 3.12-4.78 mg/100g, 2.78-3.83 mg/100g, 0.06-0.13 mg/100g, 0.03-0.08 mg/100g and0.11-0.22 mg /100g, respectively. Also, the functional properties of the flours revealed that the water absorption...........

Abstract: The objective of the study is to describe the local community agricultural changes and local community resilience in Ensaid Panjang, Sintang West Kalimantan. This study confirms that local culture in faming has been changes from slash-and-burn agriculture to modern agricultural techniques. Swidden agriculture has been recognized as part of the life everywhere in Ensaid Panjang. For indigenous community in Ensaid Panjang, the introduction of Javanese through transmigration programs, agricultural modernization and oil palm plantation development are crucial factors to changes and declines the traditional agricultural systems. Such changes are likely influence community adaptation through intensive agricultural practice by establishing wet rice field and increasing..........

Abstract: The purpose of this study is preparation and characterization of activated carbon using wood apple rind waste biomass by microwave irradiation using two different acids like sulphuric acid and phosphoric acid. A systematic investigation of the effect of dose, pH and initial concentration was done. The FT-IR analysis of the activated carbon depicts the presence of a variety of functional groups on it. The pH of the dye solution plays a major role in the adsorption process and it is the most important factor compared to all other factors that affect the adsorption process..

Abstract: The sale and distribution of garri in local markets is associated with practices such as display of product in open buckets, bowls and mats at points of sale and the use of bare hands during handling and sales.These unhygienic practices may lead to the microbial contamination of garri . This study was carried out to evaluate the microbial quality of garri soldin Ijebu community. Six garri samples were randomly collected from six retail sellers in three towns of Ijebu-igbo, Ago-Iwoye and Oru Ijebu in Ijebu-North Local Government Area of Ogun State. Samples were serially diluted to 10-2 andinoculated by pour plate method onto Nutrient agar, MacConkey agar and Potato-Dextrose agar plates for Total aerobic plate count (TAPC), Coliform count (CC) and Fungal count(FC) respectively.........

Abstract: Amphibian population declines have been reported and many causes have been implicated which include habitat alteration, environmental change and pollution. Unfortunately, not much is known of the effects of crude oil pollution on the species. This study therefore investigated the haematological changes associated with exposure of the frog, Ptychadena mascariensis to sub-lethal concentrations of the water-soluble fractions of crude oil using static renewal bioassay system for 12 weeks. Water parameters were also monitored throughout the duration of the experiment. Water quality parameters remained within the ranges for water bodies in the Niger Delta with no significant differences between the control and treatment groups. The results also revealed a dose-dependent reduction in RBC count, PCV, MCV and haemoglobin levels. As the concentration of crude oil increased, there was a corresponding significant (p<0.05) decrease in the haematology indices. This showed that the crude oil had a negative effect on the haematological indices of the frogs..

Abstract: The current dependence on the automotive fleet and certain sectors of the oil industry, the impact on the national energy matrix and the unsuccessful search for conventional hydrocarbons in the country's territory, stimulates the search and eventual exploitation of unconventional hydrocarbons that added to current technological progress, especially for the extraction of shale gas by method of hydraulic fracturing (Fracking), opens up new energy opportunities for the country. The geology of Paraguay reveals the existence of large sedimentary basins with hydrocarbon potential not yet productive due to the lack of persistence in terms of exploration. The sedimentary sequences of the Carandayty subbasin in almost their entirety consist of Paleozoic sediments with high possibilities of gas......

Abstract: The study examined the environmental refuse disposal management policies on municipal solid waste in Port Harcourt metropolis. The research work was carried out in view of the indiscriminate deposition of solid waste in urban areas like Port Harcourt. The major objective is to examine level of awareness of state policies on solid waste in Port Harcourt, identify the methods utilized in solid waste management, identify its economic benefits and identify also its problems. The hypothesis is to examine significant relationship between public awareness on environmental refuse policies and indiscriminate waste disposal. The study adopted urban ecology theory, environmental compliance model. The study adopted the case study research and a total of 144 persons were randomly selected from communities in Port Harcourt L.G.A. Well structured questionnaire was used in the study to collect data which......
