Assessment of Risk Management Practices Amongst Quantity Surveyors in the Nigerian Construction Industry

: 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 Consumption Towards a Better Future: Knowledge Practice and Attitude of college students in UAEU

 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 ...

CLIMATE CHANGE AND THE INCREASE IN INCIDENCE OF MALARIA CASES IN THE DVOKOLWAKO AREA OF SWAZILAND FROM 1990-2004

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...

ANALYSIS OF MAINTENANCE CULTURE EMPLOYED IN PUBLIC INFRASTRUCTURE IN NIGERIA

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...

Geospatial Analysis of Landuse/Landcover Changes in Wudil Town of Kano State (IJSRES-15-19)

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...

Geospatial Projection of Landuse/Landcover changes in Wudil Town of Kano State (IJSRES-15-59)

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...

Bioethanol production from date palm fruit waste fermentation using solar energy

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...

Assessment of Factors Influencing Variation in Rental Value of Residential and Commercial properties in Birnin Kebbi

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...

Energy Service Companies as a Component of a Comprehensive University Sustainability Strategy

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)...

Estimating Potential Photovoltaic Yield with r.sun and the Open Source Geographical Resources Analysis Support System

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...

Peer-to-Peer Financing Mechanisms to Accelerate Renewable Energy Deployment

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...

Limitations of Nuclear Power as a Sustainable Energy Source

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 ...

Design of Post-Consumer Modification of Standard Solar Modules to Form Large-Area Building- Integrated Photovoltaic Roof Slates

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...

A GIS Application for Location Selection and Customers' Preferences for Shopping Malls in Al Ain City; UAE

 Geographical Information Systems (GIS) are used today at several planning applications and taking advantage of information technology, this system enable the handling of both spatial and non-spatial data for constructing thematic maps describing a variety of information relating to economic activities. Current research examined the potential of suitable location as well as to study customers' preferences for shopping malls in the area. In this study, evaluation of data concerning the su...
