In many cities all over the world, urban public space has become the place of work of the urban poor. In the study by Ekpenyong and Sibiri (2011), street trading and child labour, reflected on chronic urban poverty which can compel parents/guardian to send their children/wards of school age to work to boost family income for many hours each day. The study shows that 64% of the tradeers are females while 36% of them are males. This work aimed at Analyzing the Activities of Street Tradin...
Water resources management has passed through many stages over the millenium. In the process, Integrated Water Resources Management (IWRM) was discovered and embraced as a panacea for the world’s water resources problems. Many countries in the developing realm have adopted IWRM with measurable success. Experiences in the developing countries have never come out very clear. This study attempts to have insight into how the general principles of IWRM performs at local situations in Nigeria. Th...
: The construction industry requires continuous evaluation and formulation of risk management index, but Nigeria is yet to introduce a risk rating tool for the industry. This paper therefore assessed risk management practice in Nigeria construction industry and establishes Risk Management Index (RMI). Structural questionnaire were administered to the industry stakeholders, Data collected were analysed and ranked using Relative Importance Index (RII) which w...
Energy exists in many different forms such as light energy, heat energy, mechanical energy, gravitational energy, electrical energy, sound energy, chemical energy, Nuclear or atomic energy and so on. These forms of energy can be relocated and converted between one another. When source of energy ends up as electricity, it moves with many transformations before it can power the light bulb. The aim of this study was to explore the level of student’s awareness on the importance of saving ...
The study examines the factors that account for the increase in malaria cases in Dvokolwako area (Swaziland), which in the past was generally malaria free. The two main aspects examined in the study area are climate change patterns and sugar cane cultivation under irrigation. Climatic data of the area was obtained from the Mbabane National Meteorological Service, whilst retrospective inpatient malaria data was obtained from Dvokolwako and Mliba clinics. Data on sugar cane growing was collecte...
BACKGROUND TO THE STUDYOver the years, Nigeria has had a number of laudable projects that makes one proud of being a Nigerian. These projects range from the Liberty Stadium, Ibadan (now called the Obafemi Awolowo Stadium) to the National Stadium Lagos, Universities, hospitals, schools and the refineries which got oil displacing agriculture as the mainstay of the economy to mention a few.But having been built and made to serve the immediate purpose they were meant to serve, they ended u...
Wudil is an ancient town in the savannah of northwestern Nigeria that is now growing. The growth of the town has set in landuse/landcover change in the area. In order to understand the pattern of the change, Remote Sensing and Geographic Information System techniques were used to examine the current trend in the landuse/landcover change in the area, while questionnaire survey was used to investigate the factors responsible for the change. Landsat images of the town for 2000 and 2014 w...
Wudil is an ancient town that is fast growing in Kano state of northwestern Nigeria. In spite of the continuous urbanization experienced in Wudil, accurate information on the rate and pattern of urbanization which is required for future regional development of the town is inadequate. Recent study used geospatial techniques to analyze the pattern of landuse/landcover change in the area from 2000 to 2014. Although the study provided insight on the current rate of urban growth of the town...
Every year, more than 236,807 tons, equivalent to 30% of date-palm fruits produced in Algeria, is lost during picking, storage, and commercialization processes. Gasification of this huge biomass can generate biogas such as bioethanol, biodiesel, gasoline and other useful substances. Bioethanol is becoming the main biofuel produced by chemical synthesis or anaerobic fermentation from biomass and is significant for industrial development, investment, and use. It is eco-friendly, moderately cost...
CHAPTER ONE: INTRODUCTION1.0 Background to the Study Shelter is a basic necessity in life. An individual can satisfy this need by either occupying his own (owner’s occupier) property or renting another person’s property. In our traditional society, the need for shelter is mainly met through the first alternative that is owner occupation (Jiboye 2006). With the emergency of urban centers’, the situation has changed. Ma...
The sustainability deficit observed in modern universities is not necessary to fulfill the education, research, or administrative functions of the university system, because a vast quantity of natural resources are currently wasted. The current waste thus provides a large number of opportunities to improve environmental stewardship while reducing operating costs. Guaranteed energy savings programs (GESPs), which utilize the technical and financial expertise of energy service companies (ESCOs)...
The package r.sun within the open source Geographical Resources Analysis Support System (GRASS) can be used to compute insolation including temporal and spatial variation of albedo and solar photovoltaic yield. A complete algorithm is presented covering the steps of data acquisition and preprocessing to post simulation whereby candidate lands for incoming solar farms projects are identified. The optimal resolution to acquire reliable solar energy outputs to be integrated into PV system design...
Despite the clear need to reduce greenhouse gas emissions, lack of access to capital and appropriate financing mechanisms has limited the deployment of renewable energy technologies (RETs). Feed-in Tariff (FIT) programs have been used successfully in many countries to make RETs more economically feasible. Unfortunately, the large capital costs of RETs can result in both the slow uptake of FIT programs and incomplete capture of deployment potential. Subsidies are concentrated in financial inst...
This paper provides a review and analysis of the challenges that nuclear power must overcome in order to be considered sustainable. The results make it clear that not only do innovative technical solutions need to be generated for the fundamental inherent environmental burdens of nuclear energy technology, but the nuclear industry must also address difficult issues of equity both in the present and for future generations. The results show that if the concept of just sustainability is applied ...
Building-integrated photovoltaic (BIPV) systems have improved aesthetics but generally cost far more than conventional PV systems because of small manufacturing scale. Thus, in the short and medium term, there is a need for a BIPV mounting system that utilizes conventional modules. Such a design is provided here with a novel modification of conventional photovoltaic (PV) modules to allow them to act as BIPV roofing slates. The open-source designs for the mechanical components necessary to pro...
