Uncontrolled effects through monitored activities do not protect future environmental security. This paper therefore, assesses impact of derived mining activities on landuse/ landcover in Bukuru area in Jos south of Nigeria to determine the extent of degraded mine lands. A time series analysis of Landsat MSS satellite image November 1975, Landsat TM satellite image acquired in 1989, and Landsat ETM acquired October 2005 of the study area were used. Landuse/ landcover were classified from the images using a hybrid manual and spectral based approach. The result shows that out of the 1,574.13sq.km total size of the study area, the degraded area/land, Built-up area, and water bodies increased by 24.58%, 18.51% and 7.57% respectively. Whereas Arable land (farm and grazing land) and forest reserve has decreased by 106.60sq.km (14.16%), and 264.89sq. (35.18%) respectively. It was recommended that comprehensive mitigation studies against these damages should be performed, and regular inspections should be executed to keep these activities of tin mining under control. Modern technologies should be used to obtain more effective results from these studies.

Here we investigated the relationship between the green peach potato aphid Myzus persicae Sulzer (Hemiptera: Aphididae) and its common parasitoid, Aphidius ervi Vierek (Hymenoptera: Braconidae), to determine whether the relationship is influence by infection of the aphids host by B. cinerea. In hymentopteran parasitoids which are haplodiploid, the females may selectively lay female or male eggs by controlling fertilization depending on whether the host is infected with B. Cinerea or not. Apart from infection of B. cinerea many other factors may influence the female's decision to fertilize and create biased offspring sex ratios: host quality, environment and local mate competition. It is clear that here attention was directed on parasitoids assessing host quality, especially the host size. While there was a significant effect of host plant infection on aphid size (measured as hind tibia length), and a resulting significant effect of fungal infection on the size of emerging parasitoids, there was no evidence of reduced survival or attack rates of parasitoids reared on aphids feeding on infected plants, and there was no difference in the sex ratio of parasitoids emerging from aphids reared on infected and control plants. Offspring sex is therefore not absolute; it mainly depends on relative host variability and the parasitoid's previous experience. Therefore, future research on sex allocation should consider factors that do not involve females manipulating fertilization that can create biased sex ratios.

One of them is the writing of B.A projects. Most of these undergraduate students both in L1 (English as a first language) and L2 (English as a second language) still find it difficult to argue, discuss or evaluate competently as well as persuasively in English essay writing. The present study aimed at exploring metadiscoursal choice and its influence on the success of students’ academic writing. The study was conducted within the framework of Appraisal Theory. The data was randomly generated from the written essays by thirty selected Level 400 students both from Umaru Musa Yar’adua University and Al-Qalam University Katsina. Also, the data was descriptively alaysed and presented. It was discovered that six (6) of the essays do not contain the relevant elements for this study, thus excluded from the analysis. T...

The vegetal cover in the area has to be removed from the activities of tin mining which consequently resulted into adverse environmental effect such as erosion. Different forms of human induced stress such as tin mining and heavy rainfall have severely degraded soils on the Jos Plateau. Such degradation problems are also caused by deforestation, inappropriate farming system, bush burning and over-grazing which are hostile to the environment. The impact of tin mining has greatly affected the natural ecology of the study area Bukuru. Micro and macro organisms and plants have been stripped off their natural habitat due to tin mining activities. This paper therefore, assesses the mining activities impact on the vegetation in Bukuru area of Jos plateau in Nigeria. Normalized Differential Vegetation Index (NDVI) techniques was adopted to Maps effect of tin mining on the vegetation for the period between 1975 and 2007 using LandSat satellite data. The result of the differential vegetation index analysis reveals a decline in vegetated surfaces in 1986 ranging from 0.04 to 0.58 indicating 0.05 and continuous loss in vegetation over the study area in 2007 (vegetated surface decrease by 0.08 between 1986 and 2007). The decrease in vegetated surface is due to intensive mining and cultivation.

However, awareness of dangers of increasing incidences of antimicrobial resistance (AMR) in hospitals and communities remained low. Methods a cross-sectional survey of awareness of 195 HCWs and 265 MCs toward EVD and AMR was conducted through a structured questionnaire. Results majority of HCWs (95.4%) and MCs (82.8%) still have knowledge of EVD´s danger and give reasons like its unique way of killing and unavailability of drugs for their awareness. Only 17.2% of MCs are aware of AMR as a problem, and only 3.4% of MCs and 10.3% of HCWs agreed that AMR is more dangerous than EVD. On the contrary, 76.4% of doctors, 95.1% nurses, 67.9% laboratory scientists, 66.7% pharmacists, 77.4% students and 100% of civil servants, drivers ...

A novel keratinolytic bacterium that possessed high affinity for black feather was isolated from chicken manure and identified as Pseudochrobactrum sp. IY-BUK1. Keratinase and feather soluble protein were effectively produced by the free living cells of the bacterium in media containing only black feathers and a mixture of equal amount of black-, brown- and white-coloured feathers. Complete degradation of 5 g/L of black feathers was completed in 3 days following optimisation of physico-chemical conditions. However, the bacterium selectively completed the degradation of black feather in a medium containing mixture of feathers in 144 h leaving behind approximately 33% and 45% of brown and white feathers in the medium respectively. Gellan gum-immobilised cells of strain IY-BUK1 enhanced the keratinase production by about 150% and were used repeatedly for ten cycles to degrade 5 g/L of black feather in a semi continuous fermentation of 18 h per cycle with enhanced and stable production of soluble protein. The study demonstrated the potential use of Pseudochrobactrum sp. IY-BUK1 not only in biodegradation of highly recalcitrant black feathers, but also in producing keratinase enzymes and valuable soluble proteins for possible industrial usage.
