ABSTRACT The fast growing trend of modernization and urbanization in regions around the world has its shares of dire consequences, which includes stress related problems, and have been on rise all over the world. The increasing economic growth and development has led to an intense densification of cities which have in some cases, led to a sparser availability of open spaces. Nevertheless, the need of spaces with restorative potentials is ...

ABSTRACT The geotechnical and geochemical properties of lateritic soil developed on migmatite along Ogbomosho – Ilorin road, south-western Nigeria was studied. Soil samples were collected from seven (7) different laterite profiles along the road cuts and analyzed in the laboratory so as to determine the geotechnical, geochemical and petro-graphical characteristics of each horizon within the profile and their suitability as construction and/or foundation material. The geotechnical tests conducted according to ...

ABSTRACT As technology evolves in telecommunication, the choice of the kind of radio to be used for data transfer in a multi-radio system at a particular time remains a challenge, especially in device-to-device (D2D) communications. This is evident in devices such as phones where multiple radio systems such as Bluetooth, Wireless Fidelity (WiFi), and Global System for Mobile communication (GSM) are present. Despite all these radios in place, the selection ...

ABSTRACT Building Information Modelling (BIM) is one of the most promising technology in the construction industry today.  The implementation  of BIM  has  increased  significantly over the  years;  the professionals in construction industry have realized that sharing of knowledge and information is one of the key elements of a successful contractual relationship among professionals in the construction activity in the whole life cycle of a project, lack of collaborative participation among ...

ABSTRACT This study presents the assessment of water quality of hand-dug wells in Katcha Local Government Area of Niger State, North Central Nigeria. Twenty hand-dug well water samples were analyzed in both rainy season and dry season. Standard method of water quality measurement were used to determine the Physico-chemical and Bacteriological parameters in accordance with American public health association (APHA, 1992). Values of temperature which range from 28-290C, pH which ...

ABSTRACT The geology, mineralogy and geochemistry of Ironstone around Manigi locality was investigated in order to provide a comprehensive data on the geological, geochemical and mineralogical composition. Field work, sedimentological logging, and sample collection were carried out at a road cut near Manigi in the northern part of Bida basin. Sixteen representative ironstone samples were subjected to geochemical and mineralogical studies using X-ray fluorescence spectrometry, X-ray diffraction techniques and transmitted ...

ABSTRACT A simplified comparative test procedure was developed and adopted to produce information to help farmers and other researchers in the selection and optimisation of tractors.   Two different makes of farm tractors, MF 285 and New Holland TT 75 were compared in 96 field performance tests and 24 test conditions on the Indaloke series, sandy loam soil of the research fields of National Cereal Research Institute (NCRI), Badeggi, Niger State ...

ABSTRACT Speciation of Copper, Lead, Manganese and Zinc ions in three sewage sludge samples (fresh, digested and dry) from Wupa sewage treatment plant, Abuja were investigated using sequential extraction  methods. Flame atomic absorption spectrophotometer was used for instrumental analysis. The sludge physicochemical parameters, total metal concentration using aqua regia digestion, speciation of metals under study, using   single extraction with EDTA and sequential extraction analytical methods were determined. Analysis of variance ...

ABSTRACT The study seeks to examine the impact of Tungan-kawo irrigation scheme on rice production in Wushishi Local Government Area, Niger state, Nigeria. Yamane formula was used to deduce 400 farmers/respondents from the population of the study whose response were collected through interview and copies of structured questionnaire plus field survey conducted utilizing a purposive sampling technique. The data were subjected to statistical analysis which include descriptive statistics of frequency ...

ABSTRACT Two (2) bacterial isolates obtained from Garima construction sites were named GARIMA (A) and (B), and code-named GA (A) and GA (B) respectively. They were screened for their carbonic anhydrase (CA) producing ability. Isolates GA (A) and GA (B) showed positive reaction to para-nitrophenylacetate (pNPA), producing yellow and peach/orange coloured colonies respectively. The isolates were used to produce the crude CA and the mean enzyme activity with standard error ...

ABSTRACT Pension funds are sources of long-term finance for capital investments (real  estate inclusive), as there is access to longer-term funds through contributions by employers and employees towards retirement.  Investment in real estate has an impact in both developed and developing economies. The impact of pension funds in real estate investment cannot be over emphasized, since it has pool of resources from contributions of employees of both public and private ...

ABSTRACT Aeromagnetic data was analysed and used to delineate the structural features of the upper part of Nasarawa State of Nigeria which consists of Kuje, Keffi and Akwanga. These structural features include: lineaments, faults and folds which are channels for the accumulation of solid minerals. In delineating these structural features, some enhancement techniques such as horizontal derivatives, first vertical derivative and analytical signal   were employed. Concentration maps were produced for ...

ABSTRACT The  study assessed  the  effects  of  cooperative  societies  on  women  involvement  in groundnut processing in Agricultural Zone I of Niger State, Nigeria using a sample of 205 groundnut processors  randomly selected using Taro Yamane formula at 5% error tolerance and 95% level of confidence from the study area. Specifically, the study described the socio- economic characteristics of respondents, assessed   their level of involvement in cooperative activities, determined their outputs ...

ABSTRACT Ureases are a group of enzymes that hydrolyse urea producing carbon dioxide and ammonia. Urease producing bacteria have shown their importance in microbially induced calcium carbonate precipitation in the construction industry. This study focused on the characterization of bacterial isolates from cement for concrete enhancement. Two (2) bacterial isolates assigned codes CA (B) and CA (F) were isolated from cement samples using enrichment culture technique. The isolates were screened ...

ABSTRACT Medicinal plants contain active ingredients with therapeutic values. Helianthus annuus L (Asteraceae) commonly referred to as “sunflower” has been reportedly used in managing and treating some ailments over the years. This study investigated the in vitro and in vivo antibacterial effects of the crude extracts of Helianthus annuus seeds on Salmonella spp and Eschericha coli. The phytochemical screening of the methanolic and ethanolic crude extracts revealed the presence of ...

ABSTRACT Discharge of leachate from refuse dumpsites is a source of groundwater pollution within its immediate environment of location. Geophysical investigation of an uncontrolled open solid waste dumpsite located at Barikin-Sale area of Minna was carried out for possible contamination of groundwater.   The investigation was aimed at delineating groundwater contamination due to leachate percolation thereby assessing the quality of groundwater from hand dug wells and boreholes within the dumpsite and ...

ABSTRACT Low power conversion efficiency resulting from recombination of photogenerated charges in TiO2 based photovoltaic devices has caused serious challenges in photoelectrode efficiency of such devices. Hence the need to replace TiO2 with ZnO and the composite of Zinc Oxide and Carbon Nanotube (ZnO/CNT) at optimised ratio to minimise the loss of photogenerated electrons during the photovoltaic activity is important. Hydrothermal synthesis was used to synthesis nanostructured ZnO and ZnO/CNT ...

ABSTRACT This research work used shea nut (vitellaria paradoxa) shell and cow hoof (bauhinia ungulata) as the reinforcement materials in the production of automotive brake pads. Taguchi method of experimental design and grey relational analysis were used to determine the optimal values of the manufacturing parameters. Other constituents combined together to produce the brake pad samples were epoxy resin, graphite, calcium carbonate and aluminium oxide. The optimal values obtained for  ...
