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.

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.

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 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).

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.
