A Study Of Petrophysical Properties Of The Lake Beds Of The Rukwa Basin Based On Well Log Data

ABSTRACT Well, logging is the practice of making a detailed record of the geologic formations penetrated by the well. The key purpose of well logging is to obtain petrophysical properties of reservoirs such as porosity, permeability, hydrocarbon saturation etc., for hydrocarbon exploration. Logs also tell us about the fluids in the pores of the reservoir rocks. Petrophysical parameters such as effective porosity (Φ), water saturation (Sw), formation water resistivity (Rw), hydrocarbon satur...

Climate Change, Urban Degreening And Flooding In Nigerian Cities: Reducing Vulnerability Through Polycentric Planning And Urban Greenery Strategy (PPUGS)

ABSTRACT This paper uses the Institutional Analysis and Development (IAD) framework to analyse the missing links in attempts to address the problems of flooding in Nigerian cities. Previous flooding and the recent ones have been attributed to heavy downpour, blockage of water channels and drainages, indiscriminate dumping of refuse and building of houses along channels. Areas that are neglected but pertinent to flood mitigation include: (1) degreening activities that remove green cover; (2) ...

Direct Labour System Of Project Execution In Nigeria

ABSTRACT This paper reviews the activities of direct labour approach with particular reference to my place of work. That is, Osun State College of Technology, Esa-oke. It starts by highlighting the origin of direct labour which had been in light operation since the 1930's to 1960's but which was popularised and given a full legal backing by the Shehu Shagari Administration in the late 1970's/early 1980's when the escalating cost of the contracting system of project execution became a source o...

Designing High Rise Housing For Lagos, Nigeria With Focus On Sustainable Building Services

ABSTRACT A shelter protects from sun, insect, rain, and wind, and snow, hot or cold temperature and gives you a feeling of wellbeing as well as helps you maintain your will to survive. Urbanization maybe a precursor for development and has been identified as one of the factors with profound effects on the demand for housing which rapidly causes degradation of the environment due to non-proper planning of waste discharged and amenities needed. The aim of the thesis is to create a functional H...

Investigating Effects And Management Of Flash Floods In Marigat Sub-county, Baringo County, Kenya

The purpose of the study was to investigate the effects and management of flash floods in Marigat Sub-County. The study used a descriptive research design. The target population of the study area was 24,893 households. Purposive sampling and stratified random sampling methods were used to select three locations affected by flash floods...

Factors Influencing Compliance To Environmental Legislation On Polythene Bag Ban In Rongai Sub-county, Nakuru County, Kenya

Polythene bags have been preferred for packaging purposes because they are light in weight, cheap and resistant to degradation. Despite the benefits, poor disposal of polythene causes degradation of soil, water, land and air resources leading to health problems. Burning polythene releases Greenhouse gases mainly Carbon dioxide, associated with Climate change. Furthermore, polythene kills wild game, livestock and aquatic organisms. The adverse effects of polythene bags in the country led ...
