Despite the nutritional benefits obtained from fruit consumption, the presence of heavy metals accompanying it from the environment draws scientific concerns as these affect human health. The aim of this study is to determine nutritional composition and heavy metal content of some commonly consumed fruits (apple, watermelon and sweet orange) in Nigeria. Atomic absorption spectrophotometry was used to determine nickel, cadmium, chromium, lead and copper present in fruits. The results obtained show that the three fruit species contained considerable nutritional value that may meet body needs. Additionally, there was no significant difference in heavy metal content of fruits based on different locations (ANOVA F.Test >0.05). This study posits that all fruit species had the heavy metals within world health organisation (WHO) permissible limit except apples. Apples sampled for different locations had nickel and chromium levels above the WHO permissible limits. Based on the observations in this study, there is a need for continuity of heavy metals inspection in agricultural products so as to prevent contamination and secure human safety.

Nigeria's biofuels policy advocates the adoption of cassava as feedstock for a 10%-biofuel substitution option in Nigerian transport fuel demand. This policy option is expected to address energy security and environmental consequences of using fossil fuels as the sole source of transport energy in the country. This paper appraised the technological and economic factors necessary for achieving Nigeria's cassava-based biofuel initiative at different substitution levels of 5, 10, and 15% by the Year 2020. A multi-stage energy forecasting and project analysis framework adapted from Coate's structure for technology assessment, as well as engineering economy methodology was used for the study. Technological analysis entailed determining petrol consumption projection, R and D capability, input feedstock requirements, environmental considerations and land requirement for feedstock crop production while engineering economy analysis evaluated the economic viability of the project. The results showed that petrol consumption in Nigeria and bioethanol substitution requirements were in the range of 18,285.7-19,142.84 thousand tons and 914.28 (5% low demand)-2871.43 (15% high demand) thousand tons, respectively by 2020.Cassava feedstock and landmass requirements for bioethanol production were in the range of 4.64-14.53 million tons and 4.08-12.80 thousand sq. km, respectively while carbon dioxide savings were between 1.87-5.89 million tons by 2020. The recovery price for cassava bioethanol was estimated to be US$ 0.74/litre (N 111/litre). Petrol being subsidised presently is harmful to the environment though it 'oils' the economy. Nigeria currently subsidizes petroleum products to the tune of 28% of 2011 budget. The government plans to remove this by 2012. Thus we conclude that weighing both economic and environmental benefits of bioethanol substitution in petrol consumption in Nigeria, the study showed that bioethanol production from cassava feedstock would be both technically and economically viable, provided subsidy, which depends on political will on the side of the government, is introduced for the first ten years of its implementation.

This paper examined the factors associated with the accumulation of technological capability among metalworking firms in Nigeria. A questionnaire was administered to 200 firms, of which 133 (66.5%) responded. Data were gathered on internal and external factors which are believed to influence capability build-up in the firms. The empirical evidence suggests that prior work experience of the entrepreneur, in-house training of technical staff and networking with the industry association had significant and positive influence on the accumulation of firm-level technological capability. Collaboration between the firms and research institutes was found to be weak. We conclude that firm-specific assets such as entrepreneurs' training and experience as well as in-house training are highly important for the build-up of technological capability in developing country firms. The relative importance of interaction through the industry association casts some doubt on the relevance of university-industry interactions for these firms. © 2014 The Authors.

Innovation is not just an individual act of learning by a firm or entrepreneur, but anchored within a larger system that enables and draws on the innovation process. Hence there is need to study internal and external factors that influence technological innovation outputs of small and medium enterprises (SMEs). SMEs at four industrial estates in Nigeria were sampled for this study. Several internal factors such as firm size, turnover, age, ownership, and expenditure on innovation activities did not have significant relationships with innovation output, signifying they are not the factors promoting innovation levels. Quality of human resources and interactions with suppliers as an external factor within the national innovation system (NIS) both made significant impact on innovation. Innovative performance of the firms is mainly influenced by demand or market pull factors more than technology push sources. The study recommends increasing interaction and dynamism within the NIS; substantial investment to galvanize industrial and technological capabilities of the firms and their supply chains; and adequate supply of infrastructure and funds to SMEs.

The paper examined the dimensions of innovation in small scale manufacturing firms with a view to understanding the interaction and relationship among product innovation, process innovation, organizational innovation, and marketing innovation. It further determines the relationship that exists between sales turnover and the four dimensions of innovation. Forty-six small manufacturing firms were sampled across the 4 major small scale Industrial Estates in Lagos State. The paper observed that these small firms engaged mainly in process innovation. The correlation analysis revealed a significant relationship between marketing and process innovation (r = 0.51; p<0.01) while there is no causality between product and process innovation (r = 0.31; p<0.05); product innovation and organizational innovation (r = 0.22; p<0.05); product innovation and marketing innovation (r = 0.11; p<0.05); and process and organizational innovation (r = 0.27; p<0.05) in these firms. The paper concludes that these firms are solely interested in upgrading and renewal of products, improving new methods of production, supply and distribution. The paper finally submitted that the observed trend is not unconnected with poor R&D initiative between small firms and research institutions, poor technological innovation capability of firms, and poor linkages/collaboration among stakeholder on new product development.
