Hybrid Vigour and Genetic Control of Some Quantitative Traits of Tomato (Solanum lycopersicum L.)  [PDF]
Chinedozi Amaefula, Christian U. Agbo, Godson Emeka Nwofia
Open Journal of Genetics (OJGen) , 2014, DOI: 10.4236/ojgen.2014.41005
Abstract:

Parental lines, F1 generation of domesticated tomato (Solanum lycopersicum L.) and Lycopersicon pimpinellifolium L. were evaluated at Department of Crop Science, University of Nigeria, Nsukka for improvement in their quantitative traits. The experiment was laid out in a randomized complete block design with three replications. Data were collected on the quantitative traits and fruit yield. Better Parent Heterosis (BPH), genetic variances, gene effects and heritability of the traits were estimated for the hybrids. BPH result showed that the Wild × Petomech cross had the highest positive BPH of 358.36% in fruit yield. The highest negative BPH of -95.59% was recorded for the hybrid, Wild × Grosso in average fruit weight while the hybrid, Insulata × Grosso had the lowest negative BPH of -16.27% in average fruit weight. Additive gene action and additive × additive gene action (aa) were significantly in control of three crosses, W × P, W × In and W × G in fruit yield. Additive variance was higher than dominance variance in fruit yield for all the hybrids with wild as one of its parents. Again, hybrids with wild as one of its parent as, W × G, W × In, and W × P had the highest narrow sense heritability in fruit yield (59.15%, 51.69%, 59.88%, respectively). High level of epistasis controlled some of the quantitative traits and hybridization evidenced by the result was effective in developing new tomato cultivars with positive heterotic effects in fruit yield.

Expression of Heterosis and Heritability in Vegetative Traits of Gongronema latifolia  [PDF]
Christian Ugwu Agbo, Jaime A.Teixeira da Silva
Open Journal of Genetics (OJGen) , 2014, DOI: 10.4236/ojgen.2014.42015
Abstract:

The existence of hybrid vigour with high heritability in vegetative traits of Gongronema latifolia will increase its productivity. This study was therefore undertaken to estimate heterosis and heritability in the vegetative traits of G. latifolia. Stem cuttings of five heterozygous parents of different geographical origin, and seeds of 10 hybrids resulting from their crosses were laid out in a randomized complete block design with three replications in a field. Data on the vegetative traits were obtained at the maximum growth period in each year of study and was used to estimate heterosis and heritability over the years. Better parent heterosis (BPH) ranged from -72% to 78% over three years. All the vegetative traits—with the exception of cordate base size—showed positive heterosis in a minimum of four cross combinations in two years. The cross AKS-33-EKPENE EDIENE X ANS-53-AWKA gave a higher BPH ranging from 5% to 6% in leaf area in the three years. The crosses ENS-48-MBU X IMS-50-NJIABA and ENS-48-MBU X ANS-53-AWKA gave higher BPH for leaf length and breadth for the first two years. All crosses showed positive and negative BPH for number of vines/plant and cordate base size, respectively. The hybrids ENS-48-MBU X IMS-50-NJIABA and EBS-49-ISHIAGU X IMS-50-NJIABA, with highly heritable BPH > 60 cm2 leaf area, will be selected in favour of other hybrids and parents. The selection of these hybrids will improve and maintain productivity in the species as the leaves are the harvestable part and the species is vegetatively propagated.

Abstract: Increasing generation of rice husk requires better quality disposal options in Ebonyi State, Nigeria. The common practice has been incineration or dumping into dumpsite. The enormous heaps of these rice husks which have piled up since the 1960s now constitute nuisance. Removal of this rice husk from the environment is urgently needed because of the environmental pollution and health hazards it poses to the people and the environs. This study estimates the willingness to pay (WTP) for improved waste disposal services. Findings indicated that about 95% (152) of the households were willing to pay for removal of rice husk waste with an average amount of N957. Factors that positively affected WTP for the removal of rice husk from the environment include annual income (0.001), years of education (0.013), farm size (0.051), age (0.025) and farming experience (0.008), while household size (0.003) and distances of homes/farms from rice mill centers (RMCs) (0.001) were inversely related to WTP with the R2 value of 77%. About 90% (144) of the respondents generated rice husk with an average of 23 bags (kg). The study therefore recommends among others that through the help of extension agents, the general public should be informed on the need for waste recycling and the need for attitudinal change towards recycled product.

Open Journal of Nursing (OJN) , 2013, DOI: 10.4236/ojn.2013.31008
Abstract:
Learning in the clinical environment is an integral part of nursing education programme. In tertiarybased nursing courses, students spend time learning in the clinical setting as they do in their classroombased studies. The purpose of this study was to explore teaching skills considered by undergraduate student nurses as effective in the clinical setting as well as qualities that make a clinical teacher effective. A descriptive design was employed using questionnaires to collect data. Respondents comprised year four undergraduate student nurses admitted through direct entry (DE) and university matriculation examination (UME) results. Using validated structured questionnaire, data were collected from 101 students who had completed their six months consolidated clinical experience on their perception of teaching skills and teacher qualities considered effective in the clinical setting. Data were analyzed using both descriptive and inferential statistics. Specifically, frequencies, percentage and standard deviation were used for descriptive analysis of scores while chi square and Mann-Whitney tests were used to test the mean differences in the teaching skills and to test whether there was a significant difference in their perception of teacher behaviours respectively at 0.05 level of significance. The result showed that having both clinical (professional) and teaching knowledge were the most important teaching skills for effective clinical teaching. Five qualities ranked by students as teacher behaviours important for effective teaching include being honest with students, motivation to teach, willingness to listen and using good communication skills, supervising students effectively and being positive role model. These factors could be considered when recruiting future clinical teachers and when planning inservice education programmes for clinical teachers to promote student learning.
Pattern Of Alcohol Consumption And Its Effects On Livelihood In Selected Rural Communities Of Enugu State, Nigeria
Dimelu, M. U.,Agbo, C.,Igbokwe, E. M.
Asian Journal of Agriculture and Rural Development , 2011,
Abstract: The study examined alcohol consumption and its effects on economic andsocial livelihood of selected rural communities of Enugu State. One hundred and twenty randomly selected alcohol consuming heads of households and sixty four purposively selected non-alcohol consuming heads of household were used. Data were collected using structured interview schedule and analysed using percentage. Alcoholic beverages available were palm wine (100%), beer (100%), local gin (100%), spirit (89.2%), and burukutu (41.7%). Respondents indicated preference for palm wine (50.0%). Choice of alcoholic beverage was a function of several factors namely availability, ability to produce the alcohol, cost and others. Effects of alcohol consumption wereevident by less commitment to livelihood activities, household’s welfare, incidents of violence and others. The study recommends that policies should be enacted to regulate proliferation and operation of alcohol enterprises in the rural areas. More importantly is the regulation of the type of alcohol marketed in the communities. Also government should promote programmes that target improved livelihood strategies and empowerment of rural people to enhance diversification of the rural economy.

Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.616182
Abstract: The study sought to identify initiatives required from stakeholder in the provision of school plant in primary schools in Enugu Education zone. Three research questions were developed and answered. Survey research design was adopted by the study. The population for the study was 5488 while the sample was 645 selected using proportionate random sampling technique. A 24 item structured questionnaire developed from literature reviewed was used to collect data for the study. Three experts validated the instrument. The internal consistency of the items was determined using Cronbach Alpha method and a coefficient of 0.82 was obtained. The researcher administered the instrument with the help of 3 assistants. The data collected were analyzed using mean to answer the research question while the hypothesis was tested using t-test statistics. The study found out that there were 24 initiatives (8 initiatives each by PTA members, community leaders and government respectively) required from stakeholders for provision of school plant in primary schools in Enugu Education Zone. It was therefore recommended that the identified initiatives should be implemented by the stakeholders to provide school plant in primary schools in Enugu Education zone.

Mr. Ugwu Anthony Chukwuka,Mr. Okwor Christian Anayo,Mr. Agbo Julius Amaechi
Internet Journal of Medical Update - EJOURNAL , 2008,
Abstract: This study was conducted with the objective to establish a nomogram for some left ventricular structures and their alterations in hypertension. Correlations between left ventricular structures and anthropometric variables in hypertension were also established. A sample of 320 normotensive and 80 hypertensive subjects were studied. Echocardiograhic end diastolic diameter, posterior wall thickness and septal wall thickness were obtained. Subject height, weight, age and blood pressures were obtained. Blood pressures were measured in sitting position. The values of left ventricular mass (LVM), left ventricular mass index (LVMI) and left relative wall thickness (RWT) were computed. Parametric tests were conducted. Tests were two tailed with P < 0.05 indicating statistical significance. Normal values of left ventricular structures were established; LVM: 63.72g – 336.18g, LVMI: 38.16g/m – 222.64g/m, and RWT: 0.25 – 0.52. Significant differences (P < 0.05) were established in LVM, LVMI and RWT between normotensive and hypertensive subjects. Positive and significant correlations were noted between these variables and systolic blood pressure in hypertensive subjects. A simple linear regression of RWT on Body surface area gives RWT = - 0.058 BSA + 0.475 in normotensive subjects. Normal values of left ventricular structures and a linear regression model have been established which could be used in the assessment of morbidity in hypertension.

Pakistan Journal of Nutrition , 2011,
Abstract: Tigernut tubers were processed in different ways to formulate two new products: product 1-Orange Tigernut Beverage (OTB) and product 2 - Tigernut Drink (TD). OTB was formulated from a blend of Orange Juice (OJ) and Tiger Nut Milk (TM) by substitution at ratio (OJ:TM) 100:0, 80:20, 60:40, 50:50, 40:60, 20:80 and 0:100. TD was formulated by drying tigernut tuber (8% moisture) and milling to obtain a powder. Spices were added. TD samples were obtained by reconstituting the powdered tigernut with cold water at a concentration of 5, 10, 15, 20 and 25% (w/v). The samples were evaluated for their sensory, proximate composition and microbiological status. Significant differences (p<0.05) existed between samples under various parameters. All the samples of OTB were highly acceptable but the sample (OJ:TM) 40:60 received the highest (8.3) over all acceptability. In TD, reconstituting the sample from 20 to 25% (w/v) was most (8.3-8.6) acceptable. Carbohydrate (38-50%) and moisture (39-60%) were quantitatively the major component of OTB. The samples were deficient in crude fiber. Samples (OJ:TM) 40:60 and 20:80 with carbohydrate (46%), protein (2%), ash (2-3%) and fat (3-4%) had the highest nutrient values. The reconstituted TB sample of 25% (w/v) had the highest (carbohydrate 46%, fat 22%, Ash and protein 2% respectively) nutrient level with carbohydrate, fat and moisture forming its major component. Crude fiber in TB was higher than that in OTB. A direct relationship existed between the microbial content of OTB and the rate of substitution. Microbial content ranged from no growth to 102 cfu/ml, which was not critical to the wholesomeness of the products. The TD samples showed no microbial growth thereby confirming the wholesomeness of the samples.
The Crisis of Identity and the Quest for Development in Africa: The Place of Leadership in Creating a New Culture
J Agbo
UJAH: Unizik Journal of Arts and Humanities , 2011,
Abstract: This work traces the part played by the leaders of societies, acting on the basis of certain philosophical justifications, to occasion the cultural crisis in Africa. It then shows how the activities of certain other leaders, using Japan and the U.S.A as cases in point, have worked to resolve the crisis of culture in their societies. It then argues that the African leaders are wasting a lot of time talking while their different societies are about to explode The paper sketches certain theories that already exist which the African leaders could appropriate in order to move their societies forward. It argues that just as science is a universal culture, our leaders should not wait for only solutions proffered by Africans before they can accept them. The paper argues that the prevalence of political and moral decay within African societies requires that new cultures be created by exemplary and purposeful leadership.
A Systematic Review of Studies Using the Brief COPE: Religious Coping in Factor Analyses
Christian U. Kr?geloh
Religions , 2011, DOI: 10.3390/rel2030216
Abstract: Religion is generally recognized as a major resource for dealing with stressful events, but its relationship with secular coping strategies continues to be debated. The present article provides a systematic review of the way in which analyses of the sub-scale turning to religion of the widely used Brief COPE [1] instrument are presented in peer-reviewed research articles, in order to investigate how the wealth of data published using this instrument can inform how religious coping relates to other coping strategies. Of the 212 identified articles that included turning to religion in their analyses, 80 combined sub-scale scores to form higher-order coping factors, 38 of which based on exploratory factor analyses of their own datasets. When factor analyses had used individual items as indicators, religious coping was more likely to load together with maladaptive coping strategies, and more likely with adaptive coping strategies when analyses were conducted at sub-scale level. To a large extent, the variation in the results from exploratory factor analyses appears to be due to the diverse and often inappropriate factor analytic techniques used to determine the factor structure of the Brief COPE instrument. Reports from factor analyses of the Brief COPE therefore have very little value when trying to make general conclusions about the role of religious coping in relation to secular coping methods.
