ABSTRACT Acid rain is a mixture of sulfuric acid and nitric acids depending upon the relatively quantities of oxides of sulfur and Nitrogen emissions. Theses emissions are from the exhaust pipe or smokestacks of our vehicles and others like power stations, generators, appliances and so on. Acidification of water bodies causes large scale negative impact on aquatic organism including fishes; acidification has an indirect effect on humans. It has effect on the ecosystem and causes damages to ma...
Abstract Cosmetics are care product applied to the body or face to improve appearance. The concept of beauty and cosmetics is old as mankind and civilization.

ABSTRACT Adansonia digitata L. (Malvaceae) is commonly known as baobab tree native to Africa. Baobab is a multi-purpose tree which offers protection and provides food, clothing and medicine as well as raw material for many useful items. This study aims to elucidate the metal chelating and ferric reducing potentials of methanol extracts of Adansonia digitata L. (Malvaceae) leaf using in vitro model. Phytochemical screening was carried out on the extract and it showed that the extract contains...
The introduction of combined therapy has been an important breakthrough in the treatment of HIV infection, however for proper eradication, HIV pathogenesis has to be understood. Despite treatment with combinatorial therapies, a functional cure approach would be very effective in suppressing viraemic load in the host to such low levels that the immune system would be able to control the infection without the need for antiretroviral therapy, neither inflicting harm upon the host nor transmissio...

This paper presents a systematic approach to develop a wear model of Al-Cu-Mg/Palmkernel shell ash particulate composites (PKSAp) produced by double stir -castingmethod. Four factors, five levels, central composite, rotatable design matrix was usedto optimize the number of experiments. The factors considered were sliding velocity,sliding distance, normal load and mass fraction of PKSA reinforcement in the matrix.Response surface methodology (RSM) was employed to develop the mathematicalmodel....
This study investigates the effect of firm-specific factors on the profitability of non-life insurance companies operating in Uganda to be more specific, to examine the relationship between profitability and economic factors, firm size, underwriting factor. For this purpose, secondary data of 21 non-life insurance companies operating in Uganda from the period 2004–2015 were collected from IRA. The data was analyzed using descriptive statistics, coefficient of determination (R2), standard...
To test the effect of Nauclea latifolia fruit on a diabetic rats. This was meant to see if the fruit has the ability to reduce blood sugar level.
ABSTRACT Culturally, consumption of local fermented skimmed milk (nono/tsala) is common in Northern Nigeria and many other parts of Africa and it is sometimes associated with microbial diseases due to poor hygienic practice. Hence, this study was conducted with the objectives of assessing the microbial quality and some physicochemical parameters, a purposive sampling was used to collect a total of 12 different samples from Dutse local government, Jigawa state. The results obtained showed that...
ABSTRACT Public vehicle traffic management is becoming harder, as the number of the vehicles on Nigerian roads is increasing. The Federal Road Safety Corps and other law enforcement agencies face real problems dealing with the different kinds of traffic violation, which introduces the need for an automated way to help identifying and controlling these violations. The Online vehicle recognition system, plays an important role in addressing these issues as its application ranges from parking...
ABSTRACT The emergence of multiple antibiotic resistance in bacteria and the indiscriminate use of antibiotics contribute to the dissemination of resistant pathogens in the environment which may cause problems in therapy and is a serious public health issue. This study was conducted to determine the incidence of Pseudomonas aeruginosa in clinical samples and their antibiotics resistant pattern. The organisms were isolated using standard microbiological techniques and the antibiotic susceptib...
Checking students for examination and attendance in a university environment is too cumbersome as a result of the increasing number of students. Private institutions especially are faced with problems of attaining accurate records of students’ attendance which normally involves circulating papers for students to sign in and sign out by registering their names on paper during examinations and this has proved to be stressful, time consuming, unreliable, inaccurate and inefficient. The study...

Abstract: Geography as a school subject is one of the most important subjects in senior secondary school education and it’s relevant for students in their pursue of tertiary education cannot be over emph...
It's a comparative study of African countries with the highest GDP against their food production amid the ever growing population to ascertain if truly they are under threat of food security. Abstract Sustainable food security is every nation’s goal. For a nation to achieve sustainable food security, the food supply must exceed the demand. Using trend analysis, this study is an attempt to compare the nature of food security from 2000 to 2014 in Nigeria to selected African countries in eac...
ABSTRACT The effects of variety and processing methods on the functional properties of cassava flours were studied. The functional properties of the flour were determined using standard procedures. Cassava roots were fermented, blanched, soaked, dried and milled into flour. The functional properties of the flour were determined. There were variety and method of processing influence of the functional properties significantly. The gelation capacities varied between 75% and 80% bulk density, emu...
