The electron spin resonance (ESR) linewidth of the milled powder decreases as a function of increasing temperature. On the other hand, the intensity of the signal increases with increasing temperature from 108 K to 243 K and subsequently approaches Curie-like temperature behavior above 245 K. These behaviors were understood in terms of the orbital degeneracy of fast-relaxing impurities, such as Fe3+ ion debris, from the grinding media that was embedded in the atomic structure of the milled powder and are not completely quenched. At lower temperature, only ±1/2 is occupied and the excited energy state is less likely effective in dipolar broadening compared with lower energy states of ±5/2 and ±3/2. In this regard, decrease in linewidth should be expected with increasing temperature. © 2017 The Authors

An academic library may be beautifully designed but with little impact on the research output of its users. This study identified these gaps with reference to African libraries. Researchers, irrespective of their area of interest, have a common research workflow which defines the entire research process. Information and Communication Technologies (ICT) tools can be embedded at every level of the workflow creating an enabling research environment to ease research process and better output. Academic librarians, as part of their role in supporting teaching, learning and research, are expected to introduce, advocate and create awareness and offer support services on available relevant products and services that can be embedded at every level of the research workflow. This study identified new products and services and suggested how they can be embedded through the research process. The study concluded that embedding these new products and services in research workflow will improve the quality of researches emanating from Africa and ultimately improve our research visibility globally.

Sensor Letters | Year: 2017

An electrochemical sensor based on electrochemically reduced graphene oxide (ERGO) functionalized cetyltrimethylammonium bromide (CTAB) deposited on screen printed carbon electrode (SPCE) was developed for the detection of 3-nitrophenol. The ERGO/CTAB was prepared via drop casting technique on the screen printed carbon electrode (SPCE). The drop casted composite was then subjected to cyclic voltammetry technique to produce ERGO/CTAB. The modified electrode exhibits high electrocatalytic activity and good selectivity towards the reduction of 3-nitrophenol due to its excellent electrical conductivity, strong adsorptive ability and large effective surface area of ERGO functionalized CTAB. The enhancement factor of the ERGO/CTAB modified SPCE towards 3-nitrophenol was calculated to be 5.16 times higher compared to bare SPCE. Under optimum experimental conditions, the linearity of the sensor towards 3-nitrophenol concentration was in the range of 0.5 μM to 100 μM with the detection limit of 0.04M. Furthermore, the ERGO/CTAB sensor showed good reproducibility and also demonstrated efficiency in the detection of 3-nitrophenol in water samples. © 2017 American Scientific Publishers All rights reserved.

Effect of different processing methods on chemical profile of Baobab (Adansonia digitata) seed meal was investigated. Raw Baobab seeds were collected for the study. Five different processing methods (Boiling, toasting, soaking, soak and boiling and sprouting) were used. All the processed seeds with the exception of toasted seeds were oven dried before milling for chemical analysis. Result of the study shows that raw baobab seed contains 28.85% CP with a reasonable amount of mineral and energy, it also contain some anti-nutritional factors. Processing significantly reduced crude protein, mineral and anti nutrition factors content but improved energy content. Boiling gave the least percentage reduction of crude protein and highest percentage reduction of anti nutritional factor. Boiling processing is recommended for baobab seed. © Asian Network for Scientific Information, 2014.

A study was carried out at the research farm of faculty of agriculture, Abia State University Uturu, in order to determine the hematopoietic reaction of broiler birds fed graded levels of boiled baobab seed meal as a replacement for soya beans meal. Three hundred (300) day old chicks of Anak breed were randomly allocated to five (5) treatments groups of A, B, C, D and E with 60 birds per treatment group replicated thrice of twenty (20) birds per replicate in a Complete Randomized Design (CRD). Treatment group A served as a control group fed diet free (0%) of the boiled baobab seed meal while treated groups B, C, D and E diets were replaced at 25, 50, 75 and 100% levels of baobab seed meal in place of soya beans meal. Treated diets and water were supplied ad-libitum and all management practices strictly adhered to. Blood samples were randomly collected from three (3) birds per replicate at the termination of the study at 8th weeks, after which the blood was sent immediately to the University Laboratory for analysis. Results of the findings revealed insignificant differences (p>0.05) in the mean values of PCV amongst all the treated groups (Table 2). On the other hand significant differences (p<0.05) due to treatment effects (Table 2) were observed in the mean values of Hb, RBC, WBC, MCV, MCHC, MCH, LYMPH, BASO and NEUTRO amongst the treated groups with treatments group A and B having greater mean values which were statistically different from treated groups C, D and E. However, the results of these findings were within the normal range reported by some authors signifying that the treated birds were healthy and the boiled test ingredient can be used to replace soya bean meal to the maximum level of 100% without any adverse effects in the hematological indices of the birds. © Asian Network for Scientific Information, 2015.

This study examines the causes and consequences of gully erosion, as perceived by the local people of Dangara area, Nigeria. The study particularly seeks to explore the local people’s perceptions of gully erosion and how it affects crop, settlement development, crop yields, land ownership and values, rural economics and private conservation investments in Dangara area of Nigeria’s Federal Capital Territory. It is based on analysis of data collected using questionnaires administered to 346 respondents in the area. The responses received for the various aspects considered in evaluating the respondents’ perspectives of the processes, causative factors, consequences and control measures of gully erosion in the study area were subjective to Multiple Correspondence Analysis (MCA) to detect and explore relationships between knowledge of causes of gully erosion and use of conservation measures. The results obtained indicated that the major factors causing erosion that the respondents identified in order of preference were climate, land cover, hydrology, land use and topography. For the processes, the main ones identified were slope wash and valley slope retreat, while all the other (including potholing, solution, hydraulic action, corrosion and attrition) ones were ranked with zero (0) scores indicating that the respondents were not aware of them. In the case of consequences of gully erosion, the MCA analysis indicated that livelihood, infrastructure, economy and social life were the main ones. For measures of controlling gully erosion, the analysis revealed that engineering, mechanical, land use control and agronomic measures were the ones being applied. The results obtained thus indicated that (1) the farmers were familiar with gully erosion but less aware of splash, stream bank, sheet and rill erosion; (2) the farmers did not fully understand the processes involved in gully erosion; (3) the respondents’ personal traits significantly influenced the level of their perception of the problem in the area; (4) only the uneducated among the respondents claimed to largely be unaware of gully problem in the area; (5) most of the respondents were aware of gully erosion-control measures such as sand filling, terracing, afforestation, planting of cover crops, grazing control and road construction control but could not adopt to them; and (6) the main control measures being adopted by the people include avoiding cultivating steep slopes, contour ploughing across slope, stopping land scarification, crop rotation, bush burning control, fallowing and strip cropping. These findings suggest that promoting gully erosion control in the area requires that adequate attention be given towards educating the people on the processes of gully development and the values of adopting new control measures as well as those they were aware of but have not been adopting. Since the farmers were not adopting some of the measures they are aware of largely due to lack of technical and financial base, there is the need for the development and adoption of strategies that could improve their technical and financial capabilities to enhance their capability for adopting them. In order to enhance capacity of the people of the studied community, there is the need to develop and adopt strategies that could improve technical and financial bases of the people in the area. It was further recommended that any policy aimed at comprehensively addressing gully erosion in the area must address the differences in people’s perception of the problem at the outset. © 2014, Springer Science+Business Media Dordrecht.

Realizing the importance of individual elements to human body, 14 different food samples (mainly cereals: beans, millet, sorghum and rice) collected from two different countries; Nigeria and Republic of Niger, were analyzed using Instrumental Neutron Activation Analysis (INAA) for the determination of the elemental content. Despite the commercial activity of uranium in the Republic of Niger, the concentration of Uranium, Arsenic, Chromium etc. in the studied samples show below detection limit. Elevated concentrations of K, Ca and Mg were found from the sampled beans of this work. Daily intake per person of all assessed elements were estimated and compared with Recommended Daily Intake (RDI) to establish the accumulation information of mineral, toxic and radioactive elements in the body of people of Nigeria and Niger Republic. Assessed elemental concentrations were compared with the available literature data on relevant cereals, and found reasonable agreement. Analytical quality control service (AQCS) reference material (lichen) from International Atomic Energy Agency (IAEA) was also irradiated and analyzed in this work for ensuring quality control of the method and facility (nuclear reactor) used. © International Federation for Medical and Biological Engineering 2016.

This study was conducted over a period of nine weeks to investigate the population of zooplankton raised in concrete tanks, using organic manures, as an alternative to imported expensive Artemia cysts (INVE®, USA). Cow dung, swine faeces and their mixture (50:50), were used in quantities of 1.50 g/litre, 0.46 g/litre and 0.98 g/litre, respectively, to fertilize the culture tanks under an outdoor management system. Zooplankton population was monitored for 53 days with a compound microscope and an improvised 250µ mesh-sized zooplankton net. Representative species of Cladocera and Copepoda were preserved in 70% ethyl alcohol and taxonomically identified. Results revealed that there were no significant differences (p = 0.05) among the mean zooplankton populations of the three treatments. While a significant relationship (p = 0.0098) was found between zooplankton population in cow and mixture manure-fertilized tanks, and number of days, the case was different in the swine manure fertilized culture tanks (p = 0.01). Furthermore, the temperature (25±20C) of the culture tanks during the study period had no significant effect (p = 0.01) on the zooplankton population across the three treatments. Therefore, cow and swine manures can be used to raise zooplankton under extensive outdoor conditions, as an alternative to imported expensive Artemia cysts (INVE®, USA) for feeding larvae and fry of African catfish. © 2016, Fundacion CIPAV.

A study was conducted to establish the survival and reproductive response of adults rabbits exposed to graded levels of crude oil contaminated diet. Thirty two rabbits of mixed breed of New Zealand White and Chinchilla were used in this study. The study entailed four treatment groups (designated) A, B, C and D with eight rabbits of equal sex ratio replicated four times were randomly assigned to each group. The levels of crude oil inclusion in the diet were 0.00%, (control A) 0.01, 0.02 and 0.03% for treated groups B, C and D respectively. The study lasted for fourteen weeks. There was no significant difference (p>0.05) in weight gain among the groups. The mean feed intake, average weekly body weight gain as well as final body weight were not significantly different (p>0.05) amongst the group. There was no mortality recorded at the highest inclusion rate of 0.03% in this study. Results obtained on the reproductive response revealed 68% were pregnant including the control group and 50% conception rate was recorded amongst the experimental groups. Therefore, it could be concluded that, the adult rabbits were able to survive, conceive and kindle at the highest crude oil inclusion rate of 0.03%, without any adverse effect on the experimental rabbits, hence establishing their survival level and reproductive capability of adults rabbits exposed to crude oil contamination. © Asian Network for Scientific Information, 2014.
