Development of a macroinvertebrate-based biotic index to assess water quality of rivers in Niger State, North Central Ecoregion of Nigeria.

The increasing pollution of lotic ecosystems in sub-Saharan Africa, particularly in Nigeria, poses a threat to water quality, public health and biodiversity. It is therefore essential to develop appropriate tools and methods for monitoring these rivers, particularly in heavily affected areas, where these water resources are vital to the surrounding communities that are heavily dependent on them. To fill this gap, we propose to develop a multimetric index based on macroinvertebrates for the assessment of ecological quality of rivers in Niger State (NSRBI).

Networking and training for IMPROVEMENT of farm income: A case of lifelong learning (L3F) approach in West Africa.

The lifelong learning for farmers program of the Commonwealth of Learning relies heavily on innovation platforms to address the critical information gap left by agricultural research and development, which often fails to reach the intended rural farmers. The fundamental tenet is that these activities require a space for stakeholders to collaborate, overcome obstacles, and seize opportunities for agricultural development. Therefore, this study investigated the impact of networking and training on farm income in West Africa.

Estimating the distributional impact of innovation platforms on income of smallholder maize farmers in Nigeria.

This research studies the distributional effects of IP adoption on the farm income of smallholder maize farmers in Nigeria in an effort to move beyond the standard mean impact assessment of agricultural interventions. In order to account for selection bias that may result from both observed and unobserved factors, the study used a conditional instrumental variable quantile treatment effects (IV-QTE) strategy. The use of IPs greatly affects the revenue distributions of maize producers, as empirical evidence from the outcomes shows.

New Insights in the Interplay Between African Swine Fever Virus and Innate Immunity and Its Impact on Viral Pathogenicity.

The continuous spread of African swine fever virus (ASFV) in Europe and Asia represents a major threat to livestock health, with billions of dollars of income losses and major perturbations of the global pig industry. One striking feature of African swine fever (ASF) is the existence of different forms of the disease, ranging from acute with mortality rates approaching 100% to chronic, with mild clinical manifestations. These differences in pathogenicity have been linked to genomic alterations present in attenuated ASFV strains (and absent in virulent ones) and differences in the immune response of infected animals.

Bactericidal Activity Study of ZrO-AgO Nanoparticles.

In view of the continuous resistance to antibacterial agents by bacteria and the existing problems of silver nanoparticles as an antibacterial agent, this study reports on the synthesis of pure zirconium oxide, silver oxide, and ZrO-AgO nanoparticles by sol-gel method. The nanoparticles were analyzed and tested for their antibacterial activity against gram-positive bacteria of , , , and gram-negative of , and . X-ray diffraction showed the monoclinic ZrO, cubic AgO, and peaks corresponding to ZrO and AgO in their mixed samples.
