Abstract

This study evaluated the roles of teacher counsellors and school administrators in promoting guidance and counselling programmes in some selected secondary schools in the metropolis of Sokoto state. Descriptive survey design was used in this study. The participants in this study comprise 35 teacher counsellors, students, 15 school administrators, and 200 students in five selected public senior secondary schools in Sokoto metropolis. The sample size (250 respondents) of the study was obtained using simple random sampling technique. Data were collected from the participants using three sets of questionnaires. This finding showed that majority of the respondents indicated their agreements on all the stated counsellors’ and administrators’ roles in enhancing guidance and counselling programmes in secondary schools. This finding indicated that integrated guidance and counselling services in schools help to create conducive learning environment, identify and address the students’ educational, social, emotional, and behavioral needs as well as enhancing their academic performance. There is need for collaboration between teacher counsellors and school administrators to promote guidance and counselling programmes in secondary schools.

Abstract

Cellulose is the primary component of lignocellulosic biomass and the main source of renewable materials in chemical industry. This study aims at optimizing the production of levulinic acid from cellulose derived from millet stalk using Taguchi experimental design approach. The millet stalks were pretreated by acid and alkali treatment method. The extractives, hemicellulose, lignin, and cellulose contents of the millet stalks were estimated using dry-weight basis technique. Levulinic acid production from the millet stalk was carried out in Teflon lined stainless steel autoclave (50cm3) using standard method. The optimum conditions for the production of levulinic acid were evaluated using Taguchi experimental design method. Levulinic acid was characterized using GC-MS and FT-IR techniques. The cellulose content of the millet stalk was significantly (p < 0.05) higher than the other components. FT-IR spectrum showed the presence of O-H, C=O, C-H, and C-O stretch in the levulinic acid. The highest (95%) yield of the levulinic acid was obtained with an acid concentration of 0.2M at 2000C, for 4 hours. The optimum temperature, acid concentration, and time for the production of levulinic acid from the millet stalk were 2000C, 0.2M, and 4 hours, respectively. Levulinic acid is characterized by a range of functional groups.Keywords: Cellulose, Levulinic acid, Millet stalk, Optimization, Taguchi design

Abstract

Bacterial infections have been a major health challenge associated with high morbidity and mortality rates. Plants and their metabolite constituents are important in local therapies and drug synthesis. This study aimed to evaluate the phytochemical composition and anti-bacterial activity of the methanol leaves extract of Vernonia amygdalina. Phytochemicals in the extract were estimated using standard analytical methods. The antibacterial activity test of the plant extract was carried out using the agar diffusion method. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined using the tube dilution method and sub-culturing technique, respectively. The extract contains significant amount of alkaloids (47.44 %), flavonoids (16.60 %), tannins (4.35 %), saponins (12.28 %), steroids (0.86%), and glycosides (0.18%). The extract exhibited significant (p < 0.005) inhibitory effect against Staphylococcus aureus, Streptococcus agalactiae, and Lactobacillus rhamnosus isolates with MIC and MBC values of 12.45 and 25.51 mg/mL, 22.03 and 44.84 mg/mL, and 31.64 and 63.95 mg/mL, respectively. The methanol leaves extract of Vernonia amygdalina demonstrated an inhibitory effect against Staphylococcus aureus, Streptococcus agalactiae, and Lactobacillus rhamnosus isolates with low minimum inhibitory concentration values.

Abstract

The study aims to evaluating the impact of guidance and counseling services on the academic performance of students in some selected secondary schools in Sokoto metropolis. Causal-comparative (Ex-post facto) research design was adopted for this study. This study involves a total of 200 subjects comprising 5 principals, 25 class teachers, 10 teacher counselors, and 160 students from the five selected schools. Data were collected using the four sets of questionnaires. Data analysis was done using descriptive and inferential statistics. The finding revealed that eighty percent (80%) of the students responded that their academic performance was changed after receiving counseling services. Seventy-two percent (72%) of the class teachers perceived the level of students’ academic performance after counseling as good, while 20% perceived it very good and 8% rated it bad. Guidance and counseling services have positively influenced the academic performance of the students and should be strengthened to improve the students’ performance in national examinations.
