Electrochemical Investigation of the Inhibitory Action of Ciprofloxacin Drug on the Acid Corrosion of Mild Steel

Electrochemical investigation of mild steel corrosion in acidic medium inhibited by an environmentally safe and commercially available low cost drug, ciprofloxacin, was carried out at room temperature. The results obtained show that the drug provided a good protection for mild steel in the acid medium investigated. The inhibition efficiency was found to increase with a corresponding increase in the concentration of the drug. The adsorption process that facilitated the inhibition mechanism was found to follow the Langmuir’s adsorption isotherm.

Electrochemical Linear Polarization Studies of Amodiaquine Drug as a Corrosion Inhibitor for Mild Steel in 0.1M HCL Solution

The effect of amodiaquine on corrosion of mild steel in hydrochloric acid was investigated by linear polarization resistance (LPR) electrochemical method. The results indicated that corrosion inhibition efficiency and degree of surface coverage were increased with rise in the concentration of amodiaquine. The inhibitor followed monolayer chemisorption since it obeyed the Langmuir adsorption isotherm. Keywords: linear polarization resistance (LPR), amodiaquine drug, corrosion inhibitor, mild steel, HC

Financial Control Measures and the Enhancement of Administrative Effectiveness of Principals in Secondary Schools in Akwa Ibom State, Nigeria

This study was focused on the determination of the relationship between financial control measures and enhancement of administrative effectiveness of secondary school Principals in Akwa Ibom State. The choice of this topic was necessitated by the fact that despite the continuous personnel auditing conducted in the public secondary schools in Akwa Ibom State, financial mismanagement still persists. The population of the study was 227 principals from the 227 public secondary schools in the state. The sample size for the study was 192 using stratified random sampling technique for the selection. Eighteen-item structured questionnaire designed by the researcher was used for data collection. The instrument was face validated by five experts. Three (3) null hypotheses were tested. The major findings were that the principals have not adopted budget preparation, budget implementation and internal auditing for the control of school finances. It was found that there is significant relationship between the variables and principals’ administrative effectiveness. The recommendations made based on the findings were that (1) State Secondary Educational Board should instruct principals to prepare annual budget of their schools. (2) State Secondary Education Board should properly monitor the implementation of the school budget. (3) Internal auditors should be sent by the Ministry of Education to Schools.Keywords: Control, Measures, Enhancement, EffectivenessLWATI: A Journal of Contemporary Research, 8(4), 70-77, 201

Activated Charcoal—A Potential Material in Glucoamylase Recovery

The potential of activated charcoal in the purification of fungal glucoamylase was investigated. Various concentrations of activated charcoal (1–4% w/v) were used to concentrate crude glucoamylase from Rhizopus oligosporus at different temperature values (30–50°C). Effects of pH (3.0–6.0) and contact time (0–60 min) on enzyme purification were also monitored. Activated charcoal (3% w/v) gave a 16-fold purification in a single-step purification at 50°C for 20 min and pH 5.5. The result of SDS-PAGE analysis of purified glucoamylase showed two major protein bands with corresponding molecular weight of 36 kDa and 50 kDa. The method is inexpensive, rapid, and simple which could facilitate downstream processing of industrial enzyme

Perceived Relative Factors Influencing Nurses’ Practice of Health Promotion for Women in Calabar, Cross River State, Nigeria

Socio-cultural factors negate the health of women. Therefore, health promotion as a focus of nursing practice aimed at capitalizing on the inherent capacities of women to establish health priorities, goals and strategies to improve their health. A descriptive survey with the purpose of ascertaining the influence of culture, social and health policies on nurses’ practice of health promotion was undertaken. Three hypotheses were formulated to guide the study. A sample of one hundred and thirty six nurses participated in the study. A validated questionnaire with a test-retest reliability coefficient (r) of 0.79 was used for data collection. Correlation analysis was carried out to test hypotheses. The results revealed that 132 (97.1%) participants were female with a mean (SD) age of 40 ± 7.29. Many participants 58 (42.6%) perceived that social policies have high influence on their practice of health promotion. The results also showed significant negative correlation between culture and practice of health promotion (r = -0.532; p = 0.01) while the practice of health promotion was significantly and positively correlated with social policies (r = 0.515; p = 0.01). It was recommended that negative cultural practices be addressed through social policies and health education of women on negative cultural practices in order to enhance the practice of health promotion for them

Effects of Garlic Feed Inclusion on Experimental Salmonella gallinarum Infection in Broiler Chickens (Gallus gallus domesticus)

Garlic is a spice and herbal medicine with antibacterial, antioxidant and immunomodulatory effects. In view of global demand for reduction in antibiotic use in poultry production, the potential of garlic at controlling fowl typhoid was investigated. Day-old (75) broiler chicks were separated into groups A, B, C, D and E of fifteen each, placed in cages for brooding and administered 0.125%, 0.25%, 0.5%, 0% and 0.125% garlic-meal, respectively, in feed. At 9 week-old, each chick in groups A, B, C and D were inoculated with 8x106 cfu/ml PBS of Salmonella gallinarum, orally, while those in Group E were given PBS only. Up till 10 days post-infection (pi), clinical signs were scored from 1-3 based on degree of severity i.e. 1(mild), 2 (moderate) and 3 (severe). Mortality and gross pathology per group were recorded. Samples from liver and gall bladder were harvested for bacterial re-isolation. Groups A, B and C showed mild diarrhoea while group D showed in addition, anorexia, ruffled feathers and unthriftiness. Diarrhoea in groups A and B spanned days 2 -7 pi, group C on day 3 pi while in group D, days 1-10 pi with increasing degree of severity. Total diarrhoea scores were 6(A), 4(B), 1(C), 23(D) and 0(E) while mortalities were 2(A), 0(B), 2(C), 4(D) and 0(E). Enlarged and congested/bronze-coloured liver, engorged gall bladder and catarrhal enteritis were observed in carcasses. Colonial and cellular morphology of re-isolated bacteria were typical of S. Gallinarum. Garlic-meal ameliorated the effects of S. Gallinarum infection with the best result at 0.25%. Keywords: broiler chickens; antibacterial; fowl typhoid; Garlic; Salmonella gallinaru

Awareness and practive of health promotion for women in Calabar, Cross River State, Nigeria

Aim: A descriptive survey was undertaken to ascertain nurses’ awareness and level of practice of health promotion among women in Calabar. Background: Women’s health is affected by array of factors; nurses could have a major impact in increasing women’s capacity to exercise increased control over their lives and determinants of health. Method: One hundred and thirty six nurses drawn from the ante-natal clinics of primary, secondary and tertiary health facilities in Calabar participated in the study. A questionnaire with a content validity index of 0.91 was used for data collection. The test-retest reliability coefficient of the questionnaire was (r) 0.79. Ethical issues were addressed. Data were analyzed with statistical package for social sciences (SPSS) version 15. Findings: Majority 110 (80.9%) of the participants were highly experienced, 96 (70.6%) were managers while only 52 (38.2%) had 1st degree and above. Health education was the most mentioned strategy of health promotion by participants 136 (100.0%) while specific protection was the least mentioned 3(2.2%). Only about half of the respondents 68 (50.0%) practiced health promotion appropriately. Nurses’ rank and years of working experience were significantly associated with appropriate practice. Conclusion: Nurses averagely practice health promotion. It was therefore recommended that Nurse Managers should provide learning opportunities to fill observe gaps in knowledge and motivate junior nurses to engage in women’s health promotion at every opportunity
