Throughout the world, there has been a great concern on how to totally apply science to develop people’s capacity to manage and bring on innovations. In some African countries like Nigeria where economies are still at the developmental stages, there are high rates of infrastructural dilapidations, unemployment, devaluations of currency, lack of basic infrastructure/social amenities and incessant corrupt practices to mention but a few. In all these trending challenges, the need for the role of science entrepreneurship to balance up or cushion these effects cannot be over-emphasised. In a country where unemployment rates has escalated more than the global permissible rates, there should be speedy alternatives to bring on means of livelihoods. The speedy alternatives may be the application of science to learn vocational skills such as tailoring, cosmetology, cosmetic, production of paints, baking of doughs, agricultural practices etc., all these should be done through apprenticeship and mentorship. After the apprenticeship and mentorship processes, one may set up his or her own small business (i.e., small and medium enterprise scales, SMEs) and be self-employed and self-reliant as well as creating jobs to the teaming unemployed youths, therefore contributing to the growth of the economy. This is known as science entrepreneurship. The best and preliminary way of achieving science entrepreneurship is through the ingraining of it from primary to tertiary curricula or syllabi as well as enforcement of more practical, trades and exhibitions that incorporate forty percentages (40%) of academic learnings at all levels. Nevertheless, science entrepreneurial trainings should also be extended to graduate service programmes such as National Youths Service Corps (NYSC) where every graduates within the age brackets of serving his/her father land (Nigeria) for a period of one year and those who have been exempted or excluded from serving due to their above age limits are expected to learn at least one entrepreneurial trade right from the orientation camp straight to the community development service (CDS) centre. This should be through the extension of the already begun entrepreneurial trades right from their undergraduates’ programmes. Thereafter, Government should fund/support them at the end of these trainings to help them in establishing their own small scale businesses or companies which thus creates jobs to teaming unemployed youths and also reduce the activities of juvenile delinquencies as well as contributing to the growth of the economy. To make this a reality, Government at all levels should include in her already existing ministerial or commissioning cabinets, the ministry of / or commissioner for science and entrepreneurial technology which shall oversees and monitors the progress of science entrepreneur at all levels of education.
Business intelligence (BI) has steadily become a popular information systems terminology. There are a variety of BI software packages in the industry today although it is essentially a combination of data mining, statistical analysis, and advanced report-ing features. Data mining searches for hidden patterns from a huge data warehouse so it can help managers to make business decisions. To determine the hidden pattern from a huge data warehouse, BI software’s use a variety of algorithms to find out the relationship between different data and variables. Although most of the BI the algorithms seem to be similar to traditional statis-tical techniques, data scientists are passionate to create BI software as a new decision tool. Thus, the purpose of this paper is to define most popular the algorithms and propose a model for BI software to use the algorithms according to the datasets.
In this project paper, three samples of peanut oil were collected from different locations of oil factories in Shwebo Township. The physicochemical properties such as rancidity, specific gravity, %free fatty acid, iodine value, peroxide value, and saponification value of commercial peanut oils were investigated. Moreover, the concentrations of saturated and unsaturated fatty acids in peanut oil samples were also analyzed by Gas Liquid Chromatography (GLC).
As a result of frequent insurgency activities in Nigeria, many persons are internally displaced from their homes, and many children are without access to conducive learning environments. This paper outlines some of the challenges being faced by the Internally Displaced Persons (IDPs) children and the Nomadic Herdsmen/Fishermen’s children in Nigeria. As a STEM-TVET response to these challenges, the Greening TVET group in ATBU Bauchi produced a “Green Education Mobile Learning Assistive Booth” (GEMLAB) that can help alleviate the suffering of these socially disadvantaged persons by bringing to their door steps accessible conducive learning assistive unit that is affordable and adaptable to their socio-cultural and economic predicaments. The paper also outlines some of the features, and value addition in producing this learning device (GEMLAB) as a model for solving learning problems among the socially disadvantaged groups in Nigeria, and recommends it mass production and usage among the affected groups and beyond in especially developing economies worldwide.
Manufacture industry competition requires every company to increase productivity and product quality. To increase productivity can be done by decreasing production time, one of them by decreasing setup time. This condition is a problem for small scale manufacturing that generaly have conventional machines and have financial limitations for high-tech machinery investment. One that can be done to increase productivity and reduce the number of products reject is by applying the jig and fixture. This paper will discuss the design of drilling jig and fixtures for drilling process side plate component at small scale manufacturing. The results of implementation drilling jig and fixture showed increased productivity by reducing set up time and decreasing the number of products reject.
ABSTRACT The non - compliance of staff in the Universities and Estate Surveyors and Valuers practicing in and around these universities to Building Insurance Valuation were sought. The specific objectives of this paper were to ascertain the extent of compliance by the selected universities to insurance policies of public buildings, valuation of the public buildings which are found in the Nigerian University system for insurance purpose. The survey design was used to collect the experienced opinion of estate surveyors and staff of asset and insurance units of some Universities on the compliance to BIV with the use of questionnaires.

Abstract: At the present world power generation is the most important fact for the countries and during power generation in conventional way CO2 emissions in a large scale which is burden to the global environment. To reduce emission of CO2, renewable energies can be adapted such as solar, wind, biogas etc. but among these geothermal energy (GTE) has the highest efficiency about 12%. GTE can be used for electricity generation, as heat pump, aquaculture etc. Moreover GTE has negligible CO2 emission and it is clean energy. This paper emphasizes on the modification of GTE plants using CO2 as a working fluid which emits from different reducing global warming phenomena and future prospects worldwide particularly in Bangladesh
