: The Effect of Number of Test Items and Cognitive Styles on the Learning Outcomes of Social Science. This experimental study measures the effect of test length (many test items vs. few test items) and learners' cognitive styles (field-independent vs. field-dependent) on the learning outcomes of social science. The 2 x 2 factorial design utilized shows that learners taking the test with a small number of items performed better than those taking the test with a large number of items. The field-independent learners scored higher than the field-dependent ones. The significant interaction between test length, cog­nitive styles, and learning outcomes in Social Science suggests that learners having field-independent cog­nitive style tend to achieve higher learning outcomes in tests with many items, whereas learners having field-dependent cognitive style show higher learning outcomes in tests with few items

Growth, carcass and meat characteristics of local breed of rabbits fed diets containing soaked and dried mango (Mangifera indica) seed kernel meal

This study was conducted to find substitutes for dietary maize in rabbit rations, to minimize competition between humans and livestock over the commodity. Mango seed kernel meal (MSKM) was used to substitute up to 20% of maize in rabbit rations, to assess its effects on growth, carcass and meat characteristics. Fresh mango seeds were obtained, husks were removed and seeds soaked in fresh potable water for 48 hours. The seeds were then dried to a moisture content of about 15 %, and then milled for use. Three experimental diets were formulated, where T1 (control, had no MSKM), T2 (10% of maize was replaced with MSKM) and T3 (20% of maize was replaced with MSKM). A total of 48 six-week old rabbits of indeterminate breeds (24 males and 24 females) were assigned to the three dietary treatments (16 rabbits per treatment), and were fed ad-libitumfor 6 weeks, to determine feed intake and growth rates of the rabbits. Water was however provided ad-libitum. At the end of the feeding trial, 24 rabbits were randomly selected (8 from each treatment, equal number of males and females) and were slaughtered humanely after a 12-hour feed withdrawal, for carcass and proximate analyses of the meat. Results from the study indicate that, feed intake and growth rates of the animals reduced significantly (p<0.05) when dietary maize replacement with MSKM increased beyond 10% inclusions. However, crude protein, phosphorus,potassium and zinc contents of the meat increased significantly (p<0.05) as MSKM inclusions increased. That notwithstanding, carcass parameters and organ weights were not affected by substituting up to 20% of maize with MSKM (p>0.05). It can be concluded that MSKM can efficiently be used to substitute up to 20% of maize in rabbit rations, for reduced feed cost, improved crude protein, phosphorus, potassium, and zinc contents of the meat

The Prospects and Challenges of Information Retrieval by University Students: A case study of Post Graduate Students of the University of Ghana, Legon

The poor performance of students in the various universities has been attributed to the inability of students to effectively retrieve information for academic work. The purpose of the study was to investigate the prospects and challenges of information retrieval among university students. The survey research method was used to investigate the awareness and use of information retrieval systems, document retrieved and its relevance to student’s information need, challenges of information retrieval among students and future expectation of information retrieving skills by students. Three student faculties in the University of Ghana, Legon participated in the study. A questionnaire consisting of 29 items was used as an instrument for collecting data. The findings reveal that students from all the faculties considered are highly aware of the information retrieval systems. However, there was no relationship between awareness of information retrieval systems and faculties. The study also shows that the use of information retrieval tools to retrieve relevant information depends on the information needs of the student. The study recommends that information retrieval skills training programme should be embedded in the curriculum and undertaken at an appropriate time and supported by academic staff of the University. In addition, the University administrators should ensure students studying subjects without an emphasis upon technology receive sufficient information retrieval skills training so that they are not prejudiced against due to subject chosen. Also, ensure that information retrieval skills training are pitched at a level which is appropriate to the individual needs of the student.Teaching/Communication/Extension/Profession,

Clinical utility of ultrasound imaging for measuring anterior thigh thickness after anterior cruciate ligament injury in an individual patient to assess postsurgery outcome

The present study investigated the clinical utility of ultrasound imaging (USI) for assessing changes in an individual’s quadriceps muscle and subcutaneous fat (SF) thickness of the anterior thigh and their relative proportions. A patient was studied prior to and after anterior cruciate ligament reconstruction (ACLR) surgery and during rehabilitation. This case study involved an 18-year-old female recreational athlete with a complete tear of the anterior cruciate ligament (ACL). Tissue thickness (SF and quadriceps muscle) was measured from transverse USI of the anterior thigh before surgery, at weekly intervals during 12 weeks of postsurgery, and then every 2 weeks for the following 12 weeks (total of 21 measurement sets). Statistically significant differences presurgery to postrehabilitation were found for muscle thickness () and SF tissue thickness () measurements. There was no difference in muscle to fat ratio (). Changes in measurements greater than the reported minimal detectable change (MDC) demonstrate the sensitivity of the USI technique as an objective tool to assess clinically useful changes in an individual’s anterior thigh muscle thickness post-ACLR surgery and during rehabilitation

KANDUNGAN UNSUR HARA PUPUK ORGANIK CAIR DENGAN PENAMBAHAN LIMBAH CANGKANG TELUR AYAM BROILER

Cangkang telur adalah limbah padat yang dihasilkan setiap hari oleh industri atau rumah tangga, sehingga kurangnya pengolahan limbah cangkang telur mengakibatkan peningkatan volume sampah organik. Penelitian ini bertujuan untuk menganalisis pengaruh massa cangkang telur ayam broiler terhadap jumlah dan jenis unsur hara pada pupuk organik cair cangkang telur. Penelitian ini merupakan deskriptif kuantitatif dengan parameter penelitian adalah nilai C-organik, kalium dan nitrogen. Penelitian menggunakan penambahan berat cangkang telur dalam pupuk cair dengan variasi 250 gr (perlakuan B), 500 gr (perlakuan C) dan tanpa cangkang telur (perlakuan A). Hasil uji menunjukkan unsur C-organik dan kalium tertinggi ditemukan pada perlakuan C dengan persentase 3,01% dan 1,09% secara berturut-turut. Kandungan nitrogen terbesar pada perlakuan A yaitu 0,09%. Hasil penelitian kami menunjukkan bahwa penambahan cangkang telur dapat meningkatkan kandungan C-organik dan kalium pupuk cair sehingga berkontribusi dalam upaya pengurangan sampah limbah organik

Identification of QTLs controlling resistance/tolerance to Striga hermonthica in an extra-early maturing yellow maize population

Open Access JournalStriga hermonthica parasitism is a major constraint to maize production in sub-Saharan Africa with yield losses reaching 100% under severe infestation. The application of marker-assisted selection is highly promising for accelerating breeding for Striga resistance/tolerance in maize but requires the identification of quantitative trait loci (QTLs) linked to Striga resistance/tolerance traits. In the present study, 194 F2:3 families of TZEEI 79 × TZdEEI 11 were screened at two Striga-endemic locations in Nigeria, to identify QTLs associated with S. hermonthica resistance/tolerance and underlying putative candidate genes. A genetic map was constructed using 1139 filtered DArTseq markers distributed across the 10 maize chromosomes, covering 2016 cM, with mean genetic distance of 1.70 cM. Twelve minor and major QTLs were identified for four Striga resistance/tolerance adaptive traits, explaining 19.4%, 34.9%, 14.2% and 3.2% of observed phenotypic variation for grain yield, ears per plant, Striga damage and emerged Striga plants, respectively. The QTLs were found to be linked to candidate genes which may be associated with plant defense mechanisms in S. hermonthica infested environments. The results of this study provide insights into the genetic architecture of S. hermonthica resistance/tolerance indicator traits which could be employed for marker-assisted selection to accelerate efficient transfer host plant resistance genes to susceptible genotypes
