Abstract In a capitalist housing market, provision and allocation of housing resources and units are in the hands of the gatekeepers, whose activities limit access to housing resources and units. This study examined residents’ perception on how the activities of gatekeepers constrain access to housing resources and units in the peri-urban interface of metropolitan Lagos, […]
MICROBIAL LOAD OF TWO PALAEMONID PRAWNS AND THE WATER SAMPLE FROM OVIA RIVER, NIGER DELTA, NIGERIA
Abstract A comparative study of the Microbial load of two palaemonid prawns and water samples of Ovia river, Edo state were analysed using standard methods. Total viable microbial count ranged between 1.62 x 105 and 5.58 x 105cfu/g in all samples. The highest mean bacteria count 3.27x 105cfu/g was found in the gills of M. […]
AIR POLLUTION TOLERANCE INDICES (APTI) OF SOME SELECTED PLANTS GROWING CLOSE TO IRON AND STEEL INDUSTRY IN ILE- IFE, OSUN STATE NIGERIA
Abstract The air pollution tolerance indices (APTI) of five plants species randomly sampled from the vicinity of Iron and Steel factory in Ile-Ife Osun State, Nigeria were analyzed. A composite sample of five leaves for each of the plant was used for laboratory analysis. Four physiological and biochemical parameters: leaf relative water content (RWC), ascorbic […]
GROWTH AND YIELD RESPONSES OF OKRA (Abelmoschus esculentus) IN A PETROLEUM HYDROCARBON-POLLUTED SOIL AFTER SUBSTRATE AMENDMENT
Abstract The present study investigated the effects of hydrocarbon pollution on the growth and yield performances of okra after substrate amendment. Uniform weights (10 kg) of top soil were measured into buckets and thoroughly mixed with waste engine oil (WEO) to obtain uniform concentrations of 5 % w/w. Oil-polluted soils were amended with 100 g […]
POPULATION STATUS AND ENCOUNTER RATES OF WEST AFRICAN MANATEE (Trichechus senegalensis) IN PANDAM WILDLIFE PARK, PLATEAU STATE, NIGERIA
Abstract Effective conservation measures for West African manatee in Nigeria have been very slow in progression. This study provides information on the conservation status of West African manatee through the determination of the abundance, seasonal movement and encounter rate of manatee in Pandam Lake. The visual non-motorized boat point scan survey was adopted for this […]
MORPHO-TECTONIC ANALYSIS OF TEKEZE WATERSHED IN ETHIOPIA USING GEOINFORMATICS
Abstract This study examines the morpho-tectonic settings of the drainage system in the northwestern Ethiopian plateau by focusing on the Tekeze River. The plateau is underlain by Precambrian crystalline rocks, overlain by EOCENE and Late Oligocene basalts. An attempt is made to study the underlying geology of Tekeze river basin and its significance in morphometry […]
EVALUATION OF THE DEGREE OF AGRICULTURAL MECHANIZATION INDEX ON THE PERFORMANCE OF SOME FARM SETTLEMENT SCHEMES IN SOUTHWESTERN NIGERIA
Abstract This study investigated the degree of agricultural mechanization index on the performance of farm settlement schemes in Nigeria. Seven farm settlements were selected for this study. Farm mechanization index of the farm settlements was determined and subjected to SWOT (strength, weaknesses, opportunities and threats) analysis to ascertain their internal strengths, weaknesses, external opportunities and […]
FLORISTIC COMPOSITION AND COMMUNITY ANALYSIS OF WOODY PLANTS IN HALLIDEGHIE WILDLIFE RESERVE, NORTH-EAST ETHIOPIA
Abstract This study was conducted in the Hallideghie Wildlife Reserve (HWR), North-East Ethiopia, with the aim to describe woody species composition and community types in the area. Vegetation data were collected from 66 (20 m × 20 m) plots established along five transect lines that were stratified across major vegetation types. Community types were identified […]
A SURVEY OF CURRENT PRACTICE OF PREPARING BILL OF QUANTITIES IN SOUTHWEST NIGERIA
Abstract The study explored the current practice of preparing bill of quantities by Quantity Surveyors in southwest Nigeria with a view to determining their project cost control and communication effectiveness. A survey questionnaire was administered on the 85 frontline consulting firms of Quantity Surveyors (those with not less than 10 years practice experience) in Southwest […]
REFERENCE CRITERIA FOR ECOLOGICAL RIVER HEALTH ASSESSMENT IN ETHIOPIAN HIGHLANDS
Abstract The concept of a reference condition is increasingly used to describe benchmarks against which current condition is compared. This study defines criteria that represent reference sites for assessing highland streams in four major river basins of Ethiopia. Twenty a priori criteria were chosen as representative for Ethiopian highlands and they reflect some aspects of […]
