ABSTRACT The hospitality industry is one of the fastest growing industries on the globe. The dynamics in the industry worldwide are not the same. A lot of hospitality facilities and outlets are springing out in the Ho metropolis. The present study therefore sought to assess public perception about male workers in the hospitality industry. The objectives of the study were as follows: to identify the perceptions on male workers in the hospitality industry, to examine the factors that influenc...
ABSTRACT This study looked at the extent to which information and communications technology (ICT) tools are used in Senior High Schools (SHS) in Tano South District. The study investigated the level of availability of ICT facilities in schools, the capacity for using ICT facilities for teaching and learning, the perceived benefits of using ICT tools and the problems affecting the use of ICT tools in SHS. Survey design was used for the study. The population consisted of all the teachers and st...
ABSTRACT Typical switched-mode power supplies employ diode rectifiers for the AC to DC conversion. They draw input current in short pulses rather than in smooth sine waves and this puts stress on the wiring, circuit breakers and even distribution equipment provided by utilities. This type of utility interface generates harmonics and both of the input power factor (PF) and total harmonic distortion (THD) are poor. To minimize the stresses and maximize the power handling capabilities, active ...
ABSTRACT Technological intervention is seen as any electronic item or equipment or application that is used to increase or maintain and or improve daily living work/productivity capabilities of children/students. The study assessed the impact of the “Better Ghana agenda laptops” on teaching and learning in basic schools in the Wenchi municipality, the challenges in the implementation of the policy and to find out the criteria used for the distribution of the laptops. Specifically, 100 st...
ABSTRACT Grid-connected solar PV systems, though the fastest growing renewable energy technology in the world, have not been fully exploited in Africa, one of the reasons being the very high initial investment. Prices of solar PV systems have however been on a decline for the past few years due to technological innovations which have led to improvement in cell efficiencies and the economies of scale resulting from increase in production. The main purpose of this thesis is to perform,...
Abstract Mining is viewed as the backbone of the economies of mineral rich countries and yet the exploitation of iron ore and other precious minerals in the communities of Lunsar and Bumbuna in the Northern region of Sierra Leone has nothing to write home about except severe environmental degradation and poverty. Nonetheless, the extraction of such minerals has greater potentials for economic development, industrial growth, social progress and the prosperity of a nation. Such minerals are ess...
ABSTRACT Monosodium Glutamate is a widely used food additive and flavor enhancer that is present in most soups, salads and processed meat and also present in packaged food without appearing on the label. This could result to inadvertent consumption of monosodium glutamate in high concentrations. The present study investigated the effect of monosodium glutamate on liver and testes of adult male wistar rats, by daily oral exposure of different doses. Wistar rats (n=20) of the average weight of ...
ABSTRACT Nitrification is the biological oxidation of ammonia into nitrite, followed by the oxidation of nitrite into nitrate by small groups of autotrophic bacteria and Achaea. NH3 removal is beneficial to the plant system as build up is dangerous. Presence and activities of ammonia oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB) in freshwater fishpond of a circulating aquaponics system was examined in respect to random points in the aquaponics system (the fish tank, the bio-fi...
ABSTRACT The use of ethanol in fuel blending has long been in use, and this help in controlling gas emissions but cannot be compared to bio-ethanol in control of greenhouse gas emissions. Bio-ethanol is known to adsorb CO2 they emit; it also improves rural economy. A lot of materials especially starchy crops are used in the production of bio-ethanol. This research work focuses on the production of bio-ethanol from molasses; a waste from sugar cane industries. Bio-ethanol is regarded as one of...
Abstract This paper presents the results of investigation conducted to evaluate the properties of concrete containing aluminum Roofing Sheet Waste as partial replacement of cement by weight. The properties investigated included the setting times of cement-ARSW paste, workability, density, compressive strength using 168 numbers of 150 x 150 x 150 mm cube specimens. The chemical compositions and pozzolanic properties were also investigated. The results showed that: (I.) the chemical composition...
ABSTRACT Microfinance Banks are developmental tool that focuses or centers on the extension of credit to the rural or low income earners. In recent time, most people with questionable characters had penetrated the Microfinance sector and deceive them by accessing credit facilities with false collaterals or items already used to access credits from other financial institutions. This has caused collision of various Microfinance Banks into a particular security item on default of such custom...
ABSTRACT Over the years, there have been persistent and consistent issues bordering on security in the Murtala Mohammed International Airport, Ikeja, Lagos. As an International airport as well as the gateway into our Country, it is expected to measure up to international standards in facilities, personnel, services, security, safety etc but unfortunately most of these areas are atimes neglected and consequently fall below acceptable international standards. This research has been designed...
ABSTRACT This work is to appraise the concessioning of Onne Port to Intel Nigeria Limited, the extent to which port reforms has positively influenced the development of Port Operations at Onne Port. To evaluate the developmental changes that have occurred, the researcher used statistical tools like spearman rank order and chi-square to analyze the data collected from the population of port users. Some hypotheses were developed. The study reveals that the hypothesis conducted showed that O...
ABSTRACT The current research investigated the bioavailability of gas flare pollutant fallouts in crop tissues via the soil repository matrix around the Aggah-Egbema Oil Flow Station in Ogba/Egbema/Ndoni Local Government Area of Rivers State. Three sampling locations were established at 1, 2 and 10 km from the gas flare stack. Ambient air quality for SOx, NOx, COx, H2S, suspended particulate matter (SPM10), petroleum hydrocarbons, and trace metals (Cd, Cr, Pb, Mn, Va, Zn) were determined ...
