In this paper we address the life-threatening problem of indoor CO air pollution generated by traditional indoor cooking practices in many local communities of sub-Sahara African countries. Using low cost smart wireless sensors we can provide an effective low cost life saving solution for many people and young lives today. Taking on a case study for using networkable wireless sensors we propose a new infrastructure to measure the amount of indoor carbon credit discharged during the cooking period with a view to establishing a new monitoring and control process of sending alerts through wireless channels to the fusing points. The work also reports a new networking design, practical issues and battery life management upon the measurements and simulation results.

Sensory and microbial determination of cured smoke-dried rabbit meat products were carried out under different storage conditions. Sensory attributes were determined using the 9-point Hedonic scale. Sensory evaluation of rabbit meat products in terms of overall acceptance showed there was no significant difference (p>0.05) between freshly processed unpackaged products and packaged products, stored under refrigeration temperature at 8±2·C. At p<0.05 there was significant difference between product flavour obtained from different cure types. Packaged products were also preferred to the freshly processed unpackaged products from the various cures as a result of vacuum packaging ability to prevent surface dehydration and exclude oxygen from products. Cured smoke-dried, vacuum packaged rabbit meat products could be stored under ambient temperature (26±2·C). However, products stored under refrigeration temperature (8±2·C) had stable colour than products under ambient temperature (26±2·C). The results showed that microbial population (bacterial and fungi) in rabbit meat products were significantly different (p<0.001) because of the type of treatments (Storage periods, storage temperatures, different cure). © Asian Network for Scientific Information, 2011.

The effect of carbonization on the processing characteristics of rubber seed shell powder was studied. Rubber seed shells were carbonized at different temperatures and then ground into fine powder. The various powders obtained were then characterized by pH, bulk density, moisture content, iodine adsorption value, yield%, conductivity and loss on ignition. The results show that there was a significant change in the pH as the heating temperature increases. The bulk density and moisture content decrease with increasing heating temperature while the iodine adsorption number and the loss on ignition increase with increasing heating temperature thus showing that carbonization has a significant influence on the processing characteristics of rubber seed shell. © 2012.

Samples of rubber seed shells were carbonized at varying temperatures (100, 200, 300, 400, 500, 600, 700 and 800 °C) for three hours each and sieved through a 150 μm screen. The portion of the rubber seed shell carbon that passed through the screen was characterized in terms of loss on ignition, surface area, moisture content, pH, bulk density, and metal content and used in compounding natural rubber. The characterization shows that the pH, conductivity, loss on ignition and the surface area increases with the increases of the heating temperature, unlike the bulk density which decreases. The compound mixes were cured using the efficient vulcanization system. Cure characteristics of compounds and physico-mechanical properties of the vulcanisates were measured as a function of filler loading along with that of N330 carbon-black filled natural rubbers. The results showed that the cure times, scorch times and the torque gradually increased, with increasing the filler content for rubber seed shell carbon-filled natural rubber, with the filler obtained at carbonizing temperature of 600 °C tending to show optimum cure indices. The physico-mechanical properties of the vulcanisates increase with filler loading. The reinforcing potential of the carbonized rubber seed shell carbon was found to increase markedly for the filler obtained at the temperature range of 500-600 °C and then decreases with further increase in temperature.

Over the past few decades, computer applications have extended beyond the traditional areas to non-traditional ones. Notably, real life applications often present vague, ambiguous and imprecise data. Previous investigations have shown that most current efforts to deploy ICT tools for schools management in Nigeria have resulted in multiplicity of ad-hoc incompatible information systems consisting of fragmented mixtures of single function systems that neither share data nor communicate effectively. Also, data acquired from numerous academic processes have varying degrees of imprecision, incompleteness, ambiguity, vagueness and subjectivity. Analysing the data to generate various reports for effective school administration and quality assurance presents challenges not easy to resolve with conventional information processing systems built on normal relational databases. Based on the premise that enough literature exists on systems integration standards and best practices, this study proposes a model for building a decision support system for monitoring and evaluating the performance of academic programmes in Nigerian Schools using fuzzy logic. This is achieved by using the approach proposed by Daniel Fasel to introduce fuzzy concepts into the derived multi-dimensional data schema and adding a meta table structure for classification, without affecting the core of the crisp data. This will eliminate the possibility of parallel data structures for different subsystems and allow the use of both sharp and fuzzy queries simultaneously. Specific implementation issues are examined with a case study of the University Programmes Accreditation Status Monitoring System in Nigeria. © 2013 WIT Press.

Research has shown that the carbon content of wastes decreases during composting with an increase in the nitrogen content. This indicates that the increased microbial activity in the process results in an increased mineralisation rate of organic nitrogen. A formula containing biochar in the form of terra preta, biochar bokashi, biochar glomalin, biochar hydrogel and biochar mokusaku-eki could further enhance the stability of the system and its effectiveness as a soil ameliorant. It could increase the cation exchange capacity, reuse crop residue, reduce runoff, reduce watering, reduce the quantity of fertiliser, increase crop yield, build and multiply soil biodiversity, strengthen and rebuild our soil food web, sequester atmospheric carbon in a carbon negative process, increase soil pH, restructure poor soils, and reduce carbon dioxide/methane/ nitrous oxide/ammonia emissions from gardens and fields. This paper considers these claims and also the wider environmental implications of the adoption of these processes. The intention of this overview is not just to summarise current knowledge of the subject, but also to identify gaps in knowledge that require further research. © 2015, Science Reviews 2000 Ltd.

Nigeria being the most populous nation in Africa with over 55% of its population as children and youths of school age has not witnessed corresponding development In infrastructure, educational facilities and resources to cater for the growing population of students. In quest for better standards, especially since the mid-1980s, there has been high mobility of students, academic staff and professionals. Also, new methods of delivery educational services and cross-border providers have emerged over the years, coupled with globalization issues in education, Quality Assurance (QA) in education has drawn concerns from governments, industry and other stakeholders in international education. A number of QA procedures have been presented by regulatory bodies of various nationalities. As a result of the observed disparity between the high population of school age youth in Nigeria and the Inadequate educational resources, coupled with the low level Integration of Information Technology (IT) tools in administration of education in the country, QA in education has not been fully achieved. It is of the view that except conscious and serious effort is made to develop environment specific technologies to deploy IT tools in educational administration, manual procedures for pursuing QA programmes may not yield desirable results. In this study, a model for building a system that can be used to evaluate the performance of academic programmes to determine level of compliance to Minimum Academic Standards (MAS) set by the appropriate regulatory bodies is provided with the architectural framework for building the performance evaluation system.

Artificial drying of cocoa beans has become imperative as a result of the drudgeiy and the spoilage of the beans when they are dried naturally viz-a-viz spreading the beans on a raised flat form to dry under the heat of the sun or using collector to collect the solar energy and use it to dry the beans. So, this study determined the drying characteristics of cocoa beans using artificial dryer and found that high dry rates are achieved when there is increase in drying air temperature and velocity. © Medwell Journals, 2012.

The economy of Nigeria is not solid minerals driven like that of a country like South Africa. Although several mineral occurrences have been identified in the country, their actual mode of occurrence, mineralogical composition and reserves are not known. This article reviewed the pattern of occurrence of the presently known mineral ores in Nigeria with a view to suggesting a pattern for detailed investigation for accurate chemical and mineralogical compositions and ore reserve estimation for easy investment planning. The results revealed a specific pattern of occurrence of some minerals or group of minerals in some geographic locations in the country. The presently known mineral ores are drawn in maps to present a pictorial view of their pattern of occurrence. It is found that this known pattern could be used to undertake a less expensive detailed investigation of these mineral deposits to create a reliable database of their actual compositions and reserves. © 2006-2010 Asian Research Publishing Network (ARPN).

Starch/Staerke | Year: 2013

Hydroxypropyl derivatives were prepared from the native starches isolated from lima bean and jack bean. Both native and hydroxypropylated starches were evaluated for functional, rheological and thermal properties. Molar substitution (MS) value ranged from 0.24 to 0.37 while degree of substitution (DS) from 0.02 to 0.04. The values of swelling power, solubility and pasting parameters of the native starches were significantly different from the hydroxypropyl derivatives with deviations of insignificant difference obtained for lima bean starches. Non-Newtonian shear-thinning behaviour was exhibited by all the samples. Their viscosity consistency, K, deduced from Herschel-Bulkley model, increased progressively with MS. Starches at low-substitution possessed high shear viscosities compared to the native and high-substituted starches. Increase in yield stress (ωo) was observed at low-substitution level and decrease at high-substitution level of hydroxypropylation. Upon hydroxypropylation, enthalpies of gelatinisation (δHgel) increased whereas the transition gelatinisation temperatures (To, Tp and Tc) decreased. Comparatively, lower values of transition temperature and enthalpy were obtained for retrograded starch gels than the gelatinised gels.Upon hydroxypropylation, native starches experienced increase in MW and polydispersity index (PDI). All the native starches exhibited type-A XRD patterns, which remained unchanged after hydroxypropylation. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
