Abstract

This study investigated alcohol use, anxiety and demographics as predictors of aggressive behaviour among adolescents in Ibadan and Uyo metropolises. It was a cross-cultural survey utilizing an ex-post facto design. A total of 447 purposively sampled adolescents from Yoruba and Ibibio cultures participated in the study. Revalidated Alcohol Use Identification Test by Babor, Higgins-Biddle, Saunders & Monteiro (1993) State-Trait Anxiety Inventory by Spielberger (1983), and Aggressive Scale by Orpinas & Frankowsk (2001) were used to collect data. The Pearson-r results {r= .19, df = 445, p<.05} showed that alcohol use positively correlated with aggression, the results {t (445) = 4.89, p<.05} and {R² = .32, F (6, 441) = 7.26, p < .05} indicated that anxiety and demographic factors respectively predicted aggressive behaviour among the participants. Gender, family type, perceived parenting style, family size, and parental marital status independently predicted aggressive behaviour among the participants. Moreso, the 4 {t (445) = 1.46, p>.05} indicated that adolescents who were of the Yoruba culture were not significantly different in aggressive behaviour from those who were of the Ibibio culture.  Age was not an independent predictor. It was suggested that adolescents, parents, guardians, and teachers should be mindful of these factors while psychologists and other behaviour scientists develop valid intervention programmes to curb the aggression among adolescents.

Abstract

The modulus of rupture of three clay samples were investigated to determine the effect of particle size distribution on them. The samples were collected from natural deposits at Nsu-Ehime; Ohia- Umuahia and Awo- Omamma, all in south eastern Nigeria. The particle size distribution of the clays were determined by laser diffraction technique. Thermo physical and thermo-mechanical parameters of the clays were also tested. Comparison of the modulus of rapture of the three clay samples with their particle size distributions revealed that a high proportion of the larger sized particles, (21 µm-51µm) will lower the modulus of rupture of the clay. Awo-Omamma clay contains 16.14% of these size fractions. Nsu and Ohia clays contain 4.05% and 6.65% of these size fractions respectively. Correspondingly, Nsu clay has better modulus of rupture results than Ohia clay and Awo-Omamma clay. Nsu clay and Ohia clay will perform well in most structural and technical ceramic applications. Awo-Omamma clay would require proper blending with other ingredients to produce a similar performance.

Abstract

The study was carried out to investigate the effect of the aqueous extract of helianthus annuus L seed and time of treatment on serum glucose, protein, urea, albumin, creatinine and some electrolytes using Wista albino rats as the animal model. Twenty (20) adult male wista albino rats were randomly assigned to four (4) groups of five (5) rats each. Diabetes was induced in the test and control rats by the intraperitoneal injection of alloxan monohydrate at a dose of 150mg/kg b. w. The experimental rats were administered 400mg/kg b. w single daily dose of the extract for fifteen (15) days. Diabetes was confirmed in the experimental rats by the significant increase (p<0.05) in serum glucose level. Treatment with helianthus annuus seed extract showed a significant time dependant decrease (p<0.05) in serum glucose level. The diabetic rats showed significant (p<0.05) increase in the serum levels of urea, creatinine. Treatment with the extract resulted in a time dependent significant (p<0.05) decrease in these parameters. There was a significant (p<0.05) decrease in the serum levels of total protein and albumin. Treatment with extract produced significant (p<0.05) increase in these parameters. This investigation also showed a significant (p<0.05) decrease in serum levels of Na⁺, K⁺, Ca⁺, Mg²⁺ and Cl^– in the diabetic rats. Treatment with the extract produced significant (p<0.05) time dependent increase in the levels of these electrolytes.

Abstract

Bitter leaf (Vernonia Amygdalina Deliile) (VA), family of Asteraceae is a plant that is consumed locally as food and serves important enthno-medicinal uses. It grows throughout tropical Africa to a height of about 1-5 meters and it is indigenous to many West African countries. This study was designed to evaluate the effect of aqueous extract of Vernoniaamygdalina in Wistarrats Twelve’s Adult Wistarrats weighing 89-106g were divided into three groups of four rats each. Groups 2 and 3 were administered orally with VernoniaAmygdalina aqueous extract at 0.2mg/kgBW and 0.4mg/kgBW respectively for 15 days. Group 1 was control and received 0.4ml of normal saline. The effects of aqueous extract of Vernonia Amygdalina on the body weight, liver enzyme were evaluated as well as liver architecture. After the end of administration (day 15), the weight were taking before sacrificed. After sacrifice, liver were excised and fixed in 10% formal saline, then processed for rapid routine paraffin embedding. In this research, it was observed that oral administration of aqueous extract of Vernonia Amygdalina resulted in significant increase (P<0.05) in body weight. Serum chemistry revealed significant increase (P<0.05) in ALT (alanin aminotransferase), ALP (Alkaline Phosphase) and AST (Asparate Amino Transferase) in animals treated with 0.2mg and 0.4mg of the extract relative to the control. From the result of this study, it may be concluded that the administration of aqueous extract of Vernonia Amygdalina is not toxic to wistar rats at the dose administered.

Abstract: Competitions in the mobile market has driven mobile software application organizations to meet market demand by developing applications within a short period of time which should run on different mobile platforms. As such, porting these mobile applications to other platforms once they have been developed on one platform, has been considered a desirable attribute.However, the methods used in porting these mobile applications to other platforms have been adhoc which has also affected the testing activities of the ported mobile applications. Literatures revealed that 85% of testers do not use specific models for testing mobile applications. The lack of use of specific models has also made testing of the ported mobile applications to be adhoc based.In this research, issues responsible for affecting the testing activities in porting mobile applications were identified and highlighted. Data were gathered through questionnaires and interviews and analyzed. The results showed that testing requirement phase is usually overlooked by the testing teams. The results also revealed the problem of communication between the developers and the testing teams due to lack of a well-defined testing strategy peculiar to porting mobile application.
