Abstract: Individuals with hearing impairment are confronted with a lot of problems due to the condition of their disability. This has a negative impact on their social and psychological well-being with multiplying effect on their interpersonal relationship. Therefore, this study investigated the psycho-social influence of hearing impairment on interpersonal behavior of youths with hearing loss.MethodologyThe study adopted a survey research design. A sample consisting of 211 participants with hearing loss were purposively selected from the Federal College of Education (Special) Oyo, Nigeria. A questionnaire, part of Psycho-social Competence Scale (PCS), was used for data collection with reliability coefficient of 0.72.ResultsThe findings revealed that hearing impairement affects social interaction of youths with hearing impairment, hearing loss affects emotional well-being of youths with hearing impairment and youths with hearing impairment feel inferior in company of persons without hearing impairment. Based on this, it was recommended that a friendly home environment should be made and youths with hearing impairment should be advised to accept their loss and take it as a challenge that can be used to achieve a better end and the society should have right attitude and beliefs toward youths with hearing impairment.

Ayo Babalola, Ibrahim Busu
Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.21001
Abstract: Landfill has been recognized as the cheapest form for the final disposal of municipal solid waste and as such has been the most used method in the world. However, siting landfill is an extremely complex task mainly due to the fact that the identification and selection process involves many factors and strict regulations. For proper identification and selection of appropriate sites for landfills careful and systematic procedures need to be adopted and followed. Wrong siting of landfill many result in environmental degradation and often time public opposition. In this study, attempts have been made to determine sites that are appropriate for landfill siting in Damaturu town Nigeria, by combining geographic information system (GIS) and a multi-criteria decision making method (MCDM) known as the analytic network process (ANP) for the determination of the relative importance weights of factors (criteria). The land suitability output is presented from less suitable to the most suitable areas. The final map produced show areas that are suitable for landfill siting. Based on the analysis fourteen sites were identified to fulfill the required criteria, however, only seven met the land availability criteria of twenty hectares and above. The results showed the efficacy of GIS and multi-criteria decision making method in decision making.

Abstract: This study assessed the iron, zinc and copper status of primary school-attending children in Lagos. A sample of 200 primary School-attending children was randomly selected using a stratified 2 – stage sampling technique. Data was collected in the 2 major seasons in Nigeria; Dry and Rainy seasons using dietary intake (24 hr dietary recall protocol) venipuncture blood samples, and a self-administered questionnaire. The data were analyzed using descriptive and inferential statistics. Among ages 5 - 8 years, the main dietary intake for iron was 10.66 ± 12.44 mg/d (106% of DRI), for zinc, 7.30 ± 7.39 mg/d (92% of DRI) and for copper, 1.55 ± 1.31 mg/d (390% of DRI). For ages 9 - 13 yrs, the mean intake of micronutrients showed that iron was 11.03 ± 12.72 mg/d (138% of DRI), 3inc was 8.44 ± 7.7 mg/d (105% of DRI) and copper was 3.75 ± 15.17 mg/d (536% of DRI). Biochemical results indicated that 19.8% of the subjects had inadequate serum iron, 21% and 32.1% were zinc and copper deficient respectively prevalence of anemia was 38.1% while iron deficiency anemia was 13.06% and iron deficiency was 34.6%. Dietary intakes did not provide right amounts of micronutrients to meet body requirements. There is the need to formulate and implement nutrition education programs to correct micronutrient deficiency among primary school-attending children in Lagos, Nigeria.

Ayo Adesopo
Asian Social Science , 2011, DOI: 10.5539/ass.v7n10p107
Abstract: This paper examined the negative impact of the conduct of intergovernmental fiscal relations (IGFR) on the sustenance of Nigerian federation. It showed the extent of centralization of IGFR with particular reference to the distribution of revenue-raising responsibilities and spending responsibilities as well as revenue sharing arrangement among the vertical organs of government. Specifically, the extent of fiscal centralization was examined and analysed on the basis of Federation Account operation, current revenue structure of the three vertical organs, total revenue decentralization ratio, federal-internal revenue sources ratio of the state and FCT and local government, general expenditure decentralization ratio, and summary of fiscal balance/imbalance of some selected states. The paper went further to identify the effects of the IGFR on Nigerian Federation before finally making some recommendations with emphasis on the need to revisit the fiscal relationship to resolve the recurring crises threatening its sustenance.

Abstract: The study examined the 2011 presidential election and the level of citizens’ participation in Nigeria. The study showed the preparation, challenges and the conduct of 2011 election in Nigeria with a major reference to the presidential election. The study further observed that there was an average level of citizens’ participation in the 2011 presidential poll. By embarking on comparative analysis, the participation of the electorates in the 2011 presidential election was low compared to the previous presidential elections Nigeria had in the era of fourth republic. It was revealed that incessant electoral fraud introduced into the electoral game by the politicians, loss of public confi dence and ‘do or die’ syndrome might be responsible for low level of voters’ turn out. The study also observed that the 2011 elections were just a watershed on the previous elections of the fourth republic. The study recommended that lapses of the 2011 elections should be taken care of by the INEC in order to further consolidating and deepening democracy in Nigeria. Key words: Presidential poll; Political parties; Election; Electoral fraud; Democracy Résumé L’étude a examiné l’élection présidentielle 2011 et le niveau de participation des citoyens au Nigeria. L’étude a montré les défis de préparation, et la conduite des élections de 2011 au Nigeria avec une référence majeure pour l’élection présidentielle. L’étude a également observé qu’il y avait un niveau moyen de la participation des citoyens au scrutin présidentielle de 2011. En s’engageant sur l’analyse comparative, la participation des électeurs à l’élection présidentielle de 2011 a été faible par rapport aux précédentes élections présidentielles au Nigeria avaient à l’époque de la IVe République. Il a été révélé que la fraude électorale incessante introduit dans le jeu électoral par les politiciens, la perte de la confiance du public et ‘ne meurent ou’ syndrome pourrait être responsable de faible niveau des électeurs tourner. L’étude a également observé que les élections de 2011 étaient juste un bassin versant sur les élections précédentes de la quatrième république. L’étude a recommandé que les défaillances des élections de 2011 devraient être pris en charge par la CENI en vue de consolider et renforcer la démocratie au Nigeria.

Abstract: Traditional processing of fermented maize (“ogi”), a popular weaning food in the West African sub-region, results in considerable nutrient losses. Several attempts at improving its nutritional and sensory properties have focused on fortification with plant and animal products. Banana flour, rich in micronutrients and vitamins, could increase the micronutrient and vitamin contents of ogi. This study aimed at evaluating the physicochemical properties and sensory attributes of ogi as influenced by banana flour supplementation. Fermented maize flour was substituted with ripe Cardaba banana flour at levels of 10% - 50% and the flour mixes subjected to chemical, rheological and sensory evaluation. Crude protein decreased from 1.59% to 1.43% as banana flour substitution increased, while ash, total sugar (3.64% to 4.97%), carbohydrate and acidity increased. However, diastatic activity, crude fibre and fat were not significantly (p ≤ 0.05) affected. Results of functional properties revealed the following: 86.49 - 83.63 g/ml, 0.41 - 0.44 g/cm3, 6.44 - 7.46 g/ml, 3.30 - 4.50 g/ml, and 10.40 - 10.80 g/ml for water absorption capacity, bulk density, gel consistency, syneresis and swelling capacity, respectively. Significant (p ≤ 0.05) variations were observed in the pasting viscosities of the flours. The 50:50 maize-banana flour mix was the most preferred in terms of aroma, taste, colour and general acceptability. The addition of Cardaba banana flour to ogi may enhance its micronutrient content as evidenced by increased ash content, sensory, functional and pasting properties, thereby making it a potential substitute for complementary feeding of infants.

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2010, DOI: 10.4236/jmmce.2010.94022
Abstract: This paper presents a critical review of the current work of experiment, theory of micro-nanomechanics, and numerical analysis on characterizing mechanical properties of nanocomposites. First, the classifications of nanomaterials are presented. Then nanoindentation testing and the corresponding finite element modeling are discussed, followed by analytical modeling stiffness of nanocomposites. The analytical models discussed include Voigt and Reuss bounds, Hashin and Shtrikman bounds, Halpin–Tsai model, Cox model, and various Mori and Tanaka models. These micromechanics models predict stiffness of nanocomposites with both aligned and randomly oriented fibers. The emphasis is on numerical modeling includes molecular dynamics modeling and finite element modeling. Three different approaches are discussed in finite element modeling, i.e. multiscale representative volume element (RVE) modeling, unit cell modeling, and object-oriented modeling. Finally, the mechanism of nanocomposite mechanical property enhancement and the ways to improve stiffness and fracture toughness for nanocomposites are discussed.

Abstract: Type 2 diabetes mellitus is a heterogeneous clinical entity, characterized by high blood sugar levels or hyperglycaemia, arising from a deteriorated tissue response to the biological effects of insulin (insulin resistance) [1] and impaired glucose-induced insulin secretion [2]. It is a classical example of multifactorial disorder: the etiology of type 2 diabetes combines both genetic and environmental factors. The 'westernized lifestyle' is a likely cause of the recent rapid rise in disease incidence, which is projected to double worldwide by the year 2025 (of 150 million diabetics globally, approximately 90% live in western countries). The management of type 2 diabetes and its complications accounts for a significant share of national annual healthcare spending in all western countries. Together, these facts have galvanized international efforts to research the causes of type 2 diabetes mellitus and to develop effective preventive and therapeutic tools and strategies for managing the disease.International genetic and genomic projects have delivered a wide range of tools and resources for genome-wide investigations to help the search for genetic factors involved in type 2 diabetes mellitus and have contributed to recent progress in our knowledge of the etiology of the disease (for the remainder of this article, when we say 'diabetes' we mean type 2 diabetes mellitus). Genetic markers and dense genetic maps allow extensive searches for gene variants that co-segregate with the disease. Although many genetic loci have been described that are linked to either diabetes or associated pathophysiological markers [3], CALPAIN10 remains the only known gene underlying polygenic type 2 diabetes mellitus [4].The vast amount of information derived from the annotation of the human genome and the genomes of model organisms provide opportunities for using new strategies to identify genes underlying diabetes. Knowledge of the human transcriptome and proteome provides unparalleled pow
Dietary tissue cadmium accumulation in an amazonian teleost (Tambaqui, Colossoma macropomum Cuvier, 1818)
Matsuo, AYO.;Val, AL.;
Brazilian Journal of Biology , 2007, DOI: 10.1590/S1519-69842007000400010
Abstract: understanding the effects of metal contamination in the amazon basin is important because of the potential impact on this region of high biodiversity. in addition, the significance of fish as the primary source of protein for the local human population (living either alongside the amazon river or in the city of manaus) highlights the need for information on the metal transfer through the food chain. bioaccumulation of metals in fish can occur at significant rates through the dietary route, without necessarily resulting in death of the organism. the goal of this work was to expose an economic relevant species from the amazon basin (tambaqui, colossoma macropomum) to dietary cadmium (cd) at concentrations of 0, 50, 100, 200, and 400 μg.g-1 dry food. fish were sampled on days 15, 30, and 45 of the feeding trials. tissues were collected for analysis of cd concentration using graphite furnace atomic absorption spectrophotometry. cd accumulation in the tissues occurred in the following order: kidney > liver > gills > muscle. relative to other freshwater fish (e.g., rainbow trout, tilapia), tambaqui accumulated remarkably high levels of cd in their tissues. although cd is known to affect ca2+ homeostasis, no mortality or growth impairment occurred during feeding trials.
