Land-use intensification has a direct effect on termite encounters, individuals and species richness in an ecosystem. Species richness decreases with increase in land-use intensity. The functional groups are also affected by the degree of disturbances within the land systems, with a higher percentage of damp-wood termites occurring in the primary forest, while the fungus growers are more predominant in the disturbed environment. However, termite densities are independent of land-use systems. Termite activities and decomposition of tissue paper baits increases with Increase in land-use intensity, and are independent of seasonal changes. Land-use intensification could therefore be an important factor in determining species richness, functional composition and abundance of termites in a disturbed or undisturbed ecosystem. © 2013, ALÖKI Kft., Budapest, Hungary.

Responses of African yam bean (Sphenostylis stenocarpa) to supplementary application of potassium (K) on soil were examined. Effects of the varying levels of potassium on vegetative growth, flowering, pod maturation, yield and yield components were also evaluated. There seems to be no significant mean effect (P > 0.05) upon K application on the above ground parameters of African yam bean. Similarly, soil enrichment with K had no significant effect (P > 0.05) on below ground parameters of the crop. Mineral elemental applications had no significant effect (P > 0.05) on days to 50% flowering but their effect on the number of flowers per plant for example 192.75 ± 9.87 flowers per plant in 550 kg K/Ha treatment as against 145.13 ± 18.02 flowers per plant in the control treatment were significantly different. However, grain yield per hectare increased significantly (P < 0.05) with increasing levels of K application when compared to controls. © 2010 Academic Journals.

38th Nigeria Annual International Conference and Exhibition, NAICE 2014 - Africa's Energy Corridor: Opportunities for Oil and Gas Value Maximization Through Integration and Global Approach | Year: 2014
Given the large amount of by-passed oil and gas and low oil recovery factors in many reservoirs coupled with global energy demand projected to rise as high as almost 60%in the next 30 years particularly in Africa, it is quite evident that convectional petroleum engineering techniques are not adequate and efficient for reservoir characterization and production optimization. This challenging trend may be met only by revolutionary breakthroughs in energy science and technology. The industry thus requires stunning discoveries in underlying core science and engineering which can only be accomplished through integration and global approach. Breakthroughs in nanotechnology open up the possibility of enhancing and optimizing oil and gas production beyond the current available technology by introducing innovative concepts that are more efficient and environmentally friendly. The term "nanotechnology" covers processes associated with the creation and utilization of structures in the 1.0 nanometer (nm) to 100 nm range. Nanofabrication involves engineering at the atomic length scale. It no doubt, offers substantial economic and societal benefits than any technology and holds the promise of both incremental improvements of existing products and the potential for revolutionary changes that could transform entire industries. Nanotechnology is characterized to be a multidisciplinary field, making it inherently innovative and more precise than other technologies. In this paper, the greatest potential for innovative solutions in enhanced oil recovery (particularly water flooding) through the investigation and synthesis of water-based nano-particle will be discussed.

The present study comparatively investigated the phytotoxic effects of waste engine oil (WEO)-polluted soil exposed to monitored natural attenuation up to 5 and 14 months respectively. Soil was previously polluted with WEO at 0, 1, 2.5, 5 and 10% w/w oil in soil. Although, there was significant reduction in heavy metal concentration of soil as well as total hydrocarbon contents, performance of Sphenostylis stenocarpa was greatly retarded when sown at 5 months after pollution (MAP), with death of all seedlings except in the control. However, growth and yield performances were significantly (p>0.05) enhanced at 14 MAP. Computation of hazard quotient showed that ecological risk factor initially posed by the presence of heavy metals in the soil at 5 MAP was significantly (p>0.05) reduced to safe levels at 14 MAP. © 2013 Asian Network for Scientific Information.

Castor is possibly one of Nigeria’s most under-appreciated assets. Its potential as an industrial raw material can be fully realized by a critical appraisal of its value chain. This article reviews castor value chain in Nigeria and identifies the constraints and strategies for improving its use as an industrial raw material. The strategies proposed can serve as a guide for castor value addition among operators and policy makers in a bid to maximize castor industrial potentials. A review of the uses of castor after value addition indicated that it can be used in over ten industries, namely; agriculture, food, paper, electronics and telecommunication, textile, pharmaceutical, cosmetic and perfume, paint, lubricant, plastic and rubber industries. Constraints such as insect and disease problems, weak input/service market, inadequate knowledge and skill, post-harvest losses and inadequate process technology serve as obstacles to successful value addition for castor. Strategies bordering on developing the input market, provision of quality seedlings and fertilizers, capacity development and development of farmers institutions were proposed to bridge the gaps, encourage value addition and ensure the development of castor as an industrial raw material. It is believed that if the recommendations are implemented, castor can attract up to 25 billion Naira (105,488,032 million dollars) to the Nigerian economy. © 2015, Int.
