Self Esteem among Private and Public Secondary Schools Students in Rivers State : Implications for Counselling

Abstract: The study investigated self-esteem among private and public secondary school students in Rivers State. The study used simple random sampling method to select 200 SS1 students from 3 private and 3 public schools, all in Port Harcourt municipality. The “Students Self Esteem Scale” (SSES) was use for collection of data for the study. Test-retest method was used to determine the reliability of the instrument. Reliability coefficient of 0.78 obtained. The t-test statistics was used to test two null hypotheses at 0.05 level of significance. Null hypotheses one and two were rejected, meaning that private school students, both male and female demonstrated high self-esteem, while public schools students demonstrated low self-esteem. Based on the findings of the study, four recommendations were made for effective implementations.

Effluent quality and wastes from petroleum drilling operations in the Niger Delta, Nigeria

Abstract: The research assessed the development of petroleum drilling activities and its associated waste discharges in the Niger Delta environment of Nigeria. Field visits were made to 18 wells in which petroleum drilling operation was in progress. Of this number, wastes samples were randomly collected from ten wells for data collation and laboratory analysis. Results show that petroleum drilling waste types in Nigeria include cuttings, mud/chemical, oil spills, cement slurry/dust, condemned pipes, filters, and machinery parts and even noise. Pretreatment of waste in hardly undertaken by the oil prospective companies before discharge into the surrounding environment. Total dissolved solid and oil/grease values as high as 3700mg l–1 and 1100 parts per million, respectively, were tested as effluent discharges around some of the wells studied. It was recommended that the Nigerian Government constitute a powerful environment monitoring body whose responsibility will be to ensure that the various multi‐national oil companies comply with petroleum laws and statutes of the country.

Evaluation of bunch characteristics and flour yield potential in black Sigatoka resistant plantain and banana hybrids

Abstract: Post harvest evaluation is an important criterion in the screening of plantain and banana hybrids. Processing is a means of adding value to fruits, while extending shelf life and facilitating transportation. This study aimed at determining genetic differences among plantain and banana hybrids for flour yield to facilitate adoption and industrialisation. Eleven Musa hybrids, with resistance to black Sigatoka disease were used in this study. Flour was obtained by milling dried pulps, and flour yield was expressed as percentage of the bunch weight. Significant differences in flour yield were observed across the genotypes. Among the hybrids, highest flour yield (16.5%) was obtained in 548-9, while 25273-1 had the lowest (10.3%). Flour yield did not differ significantly (p>0.05) between Obono l'Ewai (18.5%) and two of the hybrids, 548-9 (16.5%) and 25502-S4 (16.4%). However, there was a significant difference (p Musa hybrids based on high yield at harvest and flour yield potential. Plantain and banana hybrids may therefore constitute important source of flour for baking industry.

Therapeutic and Safety Evaluation of Combined Aqueous Extracts of Azadirachta indica and Khaya senegalensis in Chickens Experimentally Infected with Eimeria Oocysts.

Abstract: Coccidiosis is a disease of economic importance in poultry causing morbidity and mortality. Reports show that Azadirachta indica and Khaya senegalensis have been used individually in the treatment of avian coccidiosis. We thus investigated the efficacy and safety of the combined aqueous extracts of these plants for the treatment of experimentally induced coccidiosis in broiler chickens using oocyst count, oxidative stress biomarkers, serum biochemistry, histology, and haematological parameters. The phytochemical screening revealed the presence of tannins, saponins, cardiac glycosides, and steroids in both extracts. In addition, alkaloids and flavonoids were present in Azadirachta indica. There was significant (p < 0.05) dose dependent decrease in oocyst count across the treatment groups with 400 mg/kg of the combined extract being the most efficacious dose. Immunomodulatory and erythropoietic activity was observed. There were decreased intestinal lesions and enhanced antioxidant activity across the treatment groups compared to the negative control. Administration of the combined extract did not cause damage to the liver as ALT, AST, and ALP levels were significantly reduced in the uninfected chickens treated with the extracts compared to control suggesting safety at the doses used. The combined aqueous extracts of K. senegalensis stem bark and Azadirachta indica leaves were ameliorative in chickens infected with coccidiosis.
