- "The importance of sand bed filters has gained more ground in on- site water treatment facilities. The performance of which depends on the design of the sand bed. A laboratory column experiment was designed to quantitatively determine the best kind of sand layered arrangement for maximal bacteria attenuation. Porosity was taken as media parameter to further examine the relationship between the layers that will yield a better performance. Porosity was determined using volumetric approach and vertical downward flow for the column filtration. Escherichia coli and Staphylococcus aureus was used as contaminants. The results revealed that the larger the difference in porosity of the layers the better the filter performance and that least porous material should be below followed by the larger one arranged in the direction of flow. It was also shown that for homogeneous layered media, the more the number of layers, the better is the filter performance. These inferences would help in better design of stratified sand filter systems both for water purification and fishpond effluents treatment systems." 1 results 1
- A 21-day feeding trial involving 480, 4-week old unsexed Abhor Acre broilers was carried out in a completely randomised design to evaluate performance, carcass characteristics and cost benefit of broiler finishers fed iso- caloric and iso-nitrogenous corn-soyabean based enzyme supplemented diets. Diet 1 had no supplemented Roxazyme G and phytase (T1-basal diet). The other three diets are: T2-Roxazyme G (0.2g/kg), T3-basal diet +Phytase (lg/kg) and T4-basal diet +Roxazyme G and Phytase (0.2g/kg and lg/kg) inclusion. The objective was to observe whether addition exogenous enzymes individually or as a mixture improved efficiency of broiler finisher production. The results showed no significant differences (p>0.05) across the dietary treatments for daily feed intake, weight gain and FCR. The values obtained were in the range of 137.9g, 1191.9g and 1.45 respectively. There were no significant difference (p>0.05) in carcass weight of birds on T4, T2 and TI but birds fed both Roxazyme G and phytase had heaviest carcass weight of 1533.3g . However, birds fed diets supplemented with phytase alone had significantly lower carcass weight and dressing yield to other dietary treatments. The cut up parts were not significantly different (p>0.05) except the weights of the head, drumstick and breast meat. The cost analysis showed that it is not profitable to include the enzymes in the practical broiler finishers' diet used in this study. There was no need to include the above enzymes in the diet of broilers at finishing phase as the birds at this stage can efficiently utilize nutrients in their feed. 1 results 1
- A 56-day feeding trial to investigate the effects of stocking density, energy and protein content on performance of broiler chickens during late wet season was carried out. In a 3 x 2 x 3 factorial arrangement using completely randomized design, six diets with three energy and two crude protein levels were formulated. Three stocking densities (birds/m2) of 10, 12 and 14 were used. A total of 576 one-week old Arbor Acre broilers chickens were assigned to the respective diets and stocking density, at 32 birds per treatment. Weight gain, feed intake, feed conversion ratio, survival rate, carcass yield, live weight/m2 and feed cost / live weight were assessed. Data were analyzed, using descriptive statistics and ANOVA α0.05. Energy x crude protein x stocking density interaction affects the feed intake (p<0.05) and the highest value was obtained using diet with low energy and crude protein levels. Treatment did not affect (p>0.05) survival rate, however, stocking density at 12 birds/m2 resulted in the best values (p<0.05) of weight gain (2230.71g) and feed conversion ratio (2.10) and the use of diets with lower crude protein and energy increased (p<0.05) the weight gain (2312.42g). The carcass yield was affected (p<0.05) by the interaction of energy x crude protein x stocking density, (p<0.05) with the lowest value (67.33%) found with birds raised on stocking density, 10 birds/m2 and diets with low crude protein and recommended energy. The lowest feed cost/live weight (p<0.05) was observed with stocking density at 12 birds/m2. Broiler chickens may be economically raised at stocking density 12 birds/m2 and on diet containing 2933kcal/kg ME with 21.92% crude protein for starter phase and 3095 kcal/kg ME and 19.14% crude protein for finishers during late wet season in Nigeria. 1 results 1
- A total of 100 sows involving seven pure and crossbred genotypes of the Large White, Landrace, indigenous pigs of Nigeria and the Duroc x Large White, Duroc x Landrace and reciprocal crosses between the Large White and Landrace were used. The study embraced the milk production, milk composition and the performances of both sows and their litters. Results obtained indicate that milk production was quite low with the average eight week production of 73.99 kg of the indigenous sow to 153.21 kg of the Duroc x Large White crosses. However, percentage milk constituents were quite high with values of 19-23%, total solids, 7 - 9.2% fat, 6.9 - 7.5% protein, 4.6 - 6.0% Lactose, 0.7 - 0.9%, 0.19 - 0.35% Calcium and 0.11 - 0.20% phosphorus in both colostrum and milk. The yield of milk nutrients were similarly high, namely protein 92-175, fat 119—228 and total solids 291—576 g/sow/day and a corresponding yield of protein of 306 - 334, and fat 310 - g/kg dry matter. Litter size and litter weights at birth were quite comparable with what obtains under temperate conditions yet litter weaning weights were suboptimal in the range of 4.4 - 10 kg per piglet at eight weeks. Contrarily efficiency of milk utilization was very high and in the neighbourhood of 4 - 6 kg milk per kilogram weight gained for the pure bleeds and 2 -3 kg for the crossbreeds. Milk yield per metabolic body size was insignificantly different with values of 3.7 - 4.3 kg recorded. A high phenotypic correlation between milk and body weight at farrow could be a measure of increasing milk production of the smaller bodied indigenous pigs through selection for body size While the crossbred sows outweighed the pure breeds in their reproductive performance, all breeds suffered from seasonal fluctuation which depresses the milk production and reproductive efficiency. It can be stated that milk production of the sow is not the only limiting factor to higher productivity under the tropical condition. It is a combination of environment and management procedures in that seasonal depression has been implicated in most of the traits studied. Another major contributing factor has been the sub-clinical level of hygiene under which the animals exist. Reports have indicated that crossbreds are less susceptible to performance problems when they are bred and selected in the environments in which they are expected to perform as borne out by the results of this study. Crossbreeding might be a solution to most of these breeding problems especially by incorporating favourable genes of adaptation, disease resistance and some yet to be discovered traits in our indigenous pigs with those of the exotic purebred to develop a new breed of pig in the tropics for the tropics. The results were therefore discussed in the light of superiority of crossbreeding and adaptation of the indigenous sow. 1 results 1

- Better understanding of the genetic control of traits in breeding populations is crucial for the selection of superior varieties and parents. This study aimed to assess genetic parameters and breeding values for six essential traits in a white Guinea yam (Dioscorea rotundata Poir.) breeding population. For this, pedigree-based best linear unbiased prediction (P-BLUP) was used. The results revealed significant nonadditive genetic variances and medium to high (.45–.79) broad-sense heritability estimates for the traits studied. The pattern of associations among the genetic values of the traits suggests that selection based on a multiple-trait selection index has potential for identifying superior breeding lines. Parental breeding values predicted using progeny performance identified 13 clones with high genetic potential for simultaneous improvement of the measured traits in the yam breeding program. Subsets of progeny were identified for intermating or further variety testing based on additive genetic and total genetic values. Selection of the top 5% progenies based on the multi-trait index revealed positive genetic gains for fresh tuber yield (t ha−1), tuber yield (kg plant−1), and average tuber weight (kg). However, genetic gain was negative for tuber dry matter content and Yam mosaic virus resistance in comparison with standard varieties. Our results show the relevance of P-BLUP for the selection of superior parental clones and progenies with higher breeding values for interbreeding and higher genotypic value for variety development in yam. 1 results 1

- Educational research and indeed any other type of research is multifarious and multi disciplinary, thereby involving multi-dimensional-approach, if any research exercise were to be efficiently and effectively conducted and to yiled meaningful and utilizable results. Networking educational research could make teaching more effective as findings from a networked research undertaking could be very meaningful and usable by a larger target group than would have been yielded by educational research undertaken solo. This is because a networked educational researching would invovle the mathamtics teacher, the science teacher/educator, the economics educator, the evaluator, the education manager among others who would synthesise their knowldege, attitude and skills together for synergy teaching and learning researching, which will in turn culminate in the sharing of knowledge and skills and in specialization in the process of the researching, resulting in gaining of experience and dexterity in the undertaking meaningful research exercise which would bring about improved teaching methodology and management simultaneously. Networked educational resarch must invovle the community which higher education serves whether local, national or international. The concomitant effect of a networked research would include cross-border or in interdisciplinary or multi-diciplinary broadening of improving teaching knowldege, skills, management and methodology. This is due to the fact that findings would be shared and applied by varied people and possibly from diverse climes; cost of undertaking the project could also be minimized than if it were undertaken solo or by a few partners; effectively disseminated findings would form basis for training those who did not participate in the undertaking, but who would apply these findings in routine teaching for improved learning. 1 results 1

- Even though the wellbeing literature in psychology is fairly massive, earlier attempts at defining the term have failed to emphasize the pertinence of cultural factors in obtaining a more socially appropriate definition of the term. Hitherto, diagnostic manuals and authors in the area of mental health have been largely driven by medically related models as backgrounds in giving explanations in the area of psychological wellbeing. However, many societies (with their pre-historic values and precepts) had long existing frameworks for establishing psychological health or illness before the advent of current nosological approaches. While it is inappropriate to question the scientific basis of current theories, advancing knowledge within the vicissitudes of our historical past in the context of newer information require the adoption of current gains in scientific trails formation of the area of psychological health; considering peculiar traditional perception of mental health and illness across cultures. This paper attempts to illustrate the relevance of culture and sub-cultural practices in defining the concept of psychological well being, yet appreciating the need to situate these within the' global definition of psychological health. When this is adopted by psychologists and other mental health practitioners, establishing individual and group norms on the mental health-illness continuum will be more society and context specific. The divergence will also yield broader explanations to the existing dogmas in diagnostic criteria in mental health literature. With this in view, the discipline of psychology will be adding value to evidence based assessment and diagnosis, strengthening the insistence on reliability and validity in psychology. 1 results 1
