Laptop computers are mostly used by all society members and it has become an integral part of the student community. This study investigates the prevalence of discomfort and visual strain symptoms among college students. A sample of 15 students between the age of 20-25 years from the Home Science College, PJTSAU were selected as respondents. One third of respondents were using laptops for more than 2-4 hrs. Ninety three per cent of respondents experienced lower back pain followed by neck and wrists/hands. Majority of the respondents experienced visual strain like burning sensation, blurred vision and swelling of the eyes. Uses of real keyboards, separate mouse can reduce the incidence of postural discomforts or pain.

The purpose of the study was to evaluate properties of wetland soils along River Kaduna and suggest management needs for environmental sustainability. Two sites were identified  based on their use for arable agriculture and two profile pits were excavated in each. Soil samples were collected from the identified pedogenetic horizons. A total of 16 samples were bagged and subjected to physical and chemical analysis. The results showed that the soils were influenced by hydromorphic conditions which resulted in mottled colour features. The soils were predominantly sandy clay loam with silt and clay contents increasing at the lower horizons and otherwise for sand contents. Soil reaction ranged from strongly to slightly acidic at both sites (4.4-6.3). Organic carbon values were generally higher at the topsoils but do not follow any particular trend down the profiles. Total nitrogen was generally low while available phosphorus values ranged from low to moderate. Exchangeable bases were generally low except the magnesium contents which had high values. The cation exchange capacity was moderate to high while percentage base saturation ranged from low to moderate. For sustainable crop production in the study area, the application of organic matter complimented by split application of inorganic fertilizers is recommended.

DOI: 10.9734/JSRR/2018/43782

Aims: Nutrition knowledge is one of the factors that could influence a university student’s nutritional behaviours. This research was aimed to determined nutrition knowledge of university students in Ankara

Study Design: The study was conducted in Ankara, Turkey between May and July, 2014 in university students.

Place and Duration of Study: This was a cross sectional study.

Methodology: Out of 341 students, 66.3% were female (n=226), 33.7% were male (n=115). Our questionnaire included a demographic section, and 25 true-false nutrition knowledge questions. For the reliability of the questionnaire, the internal consistency coefficient was calculated, and the Kuder Richardson (KR-20) value was found to be 0.82. For the statistical analyses of the data, table showing mean, standard deviation ( ) and percentage (%) values were prepared. When identifying the nutrition knowledge of students, the “independent t test” was used for the as taking gender and age.

Results: The mean nutrition knowledge score was 15.8 ± 4.9. The mean score for gender was 16.6 ± 4.3 in females, and 14.2 ± 5.5 in males, and found statistically significant (p=.000).

Conclusion: In this study, was determined that nutrition information scores of the participants were moderate. This situation is the result of increasing the level of nutrition knowledge in young people. Nutrition knowledge may be effective in increasing the quality of life and decreasing the prevalence of some diseases.

Aims: This work aimed to identify SNP marker associated with QTLs controlling grain weight and protein and oil content in soybean grains, using genome wide association study (GWAS).

Study Design:  Experimental design for field study was Complete Randomized Block.

Place and Duration of Study: Departments of Breeding and Biotechnology at Coodetec in Cascavel, Palotina, Rio Verde and Sorriso, Brazil, between July 2013 and July 2016,

Methodology: A set of 168 soybean varieties were evaluated in five environments and genotyped with a panel of 6,000 SNP markers. Protein and Oil content was obtained through NIR (Near Infrared Reflectance). GWAS was made by mixed linear model and multiple regression analysis.

Results: Six QTLs in five chromosomes explained from 10.4% to 26.6% of protein variation in three environments. Eleven QTLs in seven chromosomes explained from 14.4% to 39% of oil variation in five environments. Six QTLs in five chromosome explained 32.5% and 37.1% of grain weight variation in two environments.

Conclusion: For the same trait, different QTLs was identified in different environments. It means that to use marker assisted selection for this traits in soybean breeding, the markers need to be validated or identified in the breeding population in each environment, before being used for selection.

This paper deals with the vision of Africa in the world and the position of Nigeria in the achievement or the realization of the Africa vision. Africa has chosen to embark on a long time target, with various reforms, policies, vision and strategic development programs and plans, all channeled towards achieving a better and a good Africa. In this paper it was revealed that the African union has conceived and put in place its vision for it continent in the next 50years, this vision is tagged vision 2063. This paper uses critical research method to compare and contrast, and also analyze the vision of the continent Africa and how it could be achieved considering the difference among the countries that makes up the continent. This African vision, agenda 2063 the goal of having an Africa that is rich and successful based on growth and development that is sustainable, also it purpose to have a continent that is politically united, a continent of good leadership and good governance, a collection of countries with respect for it citizen, human right, democracy, justice and rule of law. Agenda 2063 foresee an African that is peaceful and safe for people to live. Africa with common history, tradition, qualities, values, ethics and strong cultural identities. An Africa where it people drives it development making good use of the potentials of it women and youth. In this paper, Nigeria’s role in the achievement of the Africa’s vision was really emphasized. Nigeria as one of the top countries in Africa, in size, population and economy has its own impart on the achievement of the vision of its continent Africa. Nigeria as a nation has set for itself goals to pursue which will in turn bring about to achievement of the vision of Africa, such as the vision 20: 2020. The seven point agenda by late president Umaru Musa Yar’Adua which covers the basic areas of (a) power and energy, (b) food and security and agriculture, (c) wealth creation and employment, (d) mass transportation, (e) land reforms, (f) security (g) good education. The achievements of this set goals will definitely cause a rise to the spirit of enterprise by the Nigerian hence reduces poverty in Nigeria and Africa at large. As Nigeria practical execute the plans of achieving vision 20:20:20. The success in the achievement of vision 2020is highly imperative in the achievement of vision 2063.
