Multivariate statistical assessment and spatial distribution of groundwater contamination in Neke and its environs

Groundwater quality in Neke area of southeastern Nigeria was investigated applying multivariate statistical analyses using Statgraphics Centurion XVII, ArcGIS 10.2.2 and Surfer 10 software on hydrochemical and bacteriological data from 25 groundwater samples over land cover of about 1283km2 , in order to unravel the factors influencing ground water quality. From the correlation analysis, Ca2+, Mg2+, K+, and S042- appear to be the main contributors of the ground water TDS, Ca2+ shows a h...

Assessment of the impact of onsite sanitary sewage system and agricultural wastes on groundwater quality in Ikem and its environs south eastern

Physico-chemical, multivariate and bacteriological analyses were integrated to assess the impact of onsite sanitary sewage and agricultural waste on groundwater quality in Ikem and its environs using Rockworks16, Statgraphics Centurion XVII,  ArcGIS 10.2.2 and Surfer 10.  Results of the physicochemical analysis suggest that groundwater samples in the study area acidic, with very few samples having electrical conductivity and total dissolved solids above WHO standard for drinkin...

Applications of Open-Access Remotely Sensed Data for Flood Modelling and Mapping in Developing Regions

Flood modelling and mapping typically entail flood frequency estimation, hydrodynamic modelling and inundation mapping, which require specific datasets that are often unavailable in developing regions due to financial, logistical, technical and organizational challenges. This review discusses fluvial (river) flood modelling and mapping processes and outlines the data requirements of these techniques. This paper explores how open-access remotely sensed and other geospatial&...

Exploring South Africa's Leadership Potential in Climate Change Discourse in Africa

Evidence has shown that Africa, despite being the hardest-hit continent by the catastrophic effects of climate change, wields a relatively minimal influence in the ongoing global climate change debates. The inadequacy of influence is due to insufficient leadership from Africa in the global climate change negotiations. To mend this leadership challenge, South Africa has been identified as having significant potentials to lead African climate change discourse, especially, towards wielding...

Elderly Housing: Principles and Options

1.0  Introduction Housing  (shelter)  ranks  third  (after  food  and  clothing)  amongst  the  three  basic necessities of mankind. Its provision is thus of paramount consideration. There are different dimensions to defining housing. However, Cutchin (2004) described housing as shelter for human habitation, that is, provision of accommodation – houses and other buildings where people live, considered collectively. A decent home is...

Development of a Standalone Application for Unsupervised Image Classification

ABSTRACTThis project research aimed to develop a standalone computer application for image classification using Matlab 9.2 by adopting the Rapid Application Development Model (RAD). The software can be used for image preprocessing and image classification. The test run of the software was carried out using acquired LANDSAT image and Google earth image of Federal University of Technology Gidan-Kwano campus. The program was designed to accept the input image in all format for the classific...

ASSESSMENT OF THE ACCESSIBILITY OF PRIMARY HEALTH CARE DELIVERY SYSTEM IN KAURU LOCAL GOVERNMENT AREA OF KADUNA STATE, NIGERIA

ABSTRACT Improvements in access to Primary Health Care (PHC) pave the way for advancement in the quality of people’s life. This study assesses access to PHC in Kauru LGA, Kaduna State, with a view to provides necessary information for future health planning effort. The spatial locations of all the 40 healthcare facilities were ascertained using Global Position System (GPS) to create a database (using Arc map 10.0).
