Campaign against open waste dump in nigeria: the role of health communication

Abstract: Health communication is an essential tool in disseminating adequate health information and creating necessary awareness/ consciousness among the people of a geographical location. It also helps in facilitating effective decision making that enhances public health. Waste, if not properly managed often cause a serious environmental and health risk. The current unwholesome waste disposal practices and management system in Nigeria is very worrisome and poses a classic health communication challenge. The paper concluded that open waste dumpsites is the simplest way of waste disposal, as such, there is need to direct appropriate health communication strategies to change the unwholesome attitude, behavior and practices towards waste disposal and dumpsites management. It also advocates for the use of health communication to mobilize and sensitize the people towards appropriate waste disposal as well as speedy adoption of modern waste management system to ensure adequate protection of the environment and public health.

Minimum Sand Transport Conditions in Gas-Solid-Liquid Three-Phase Stratified Flow in Horizontal Pipelines

Abstract: Producing sand during oil and gas production is unavoidable. Sand is produced along with oil and gas and its deposition in pipelines is a significant risk as it can cause pipe corrosion and flow assurance difficulties. It is therefore key that flow conditions are sustained to guarantee lack of deposition of sand particles. The minimum combination of mixture velocities that guarantee continuous sand motion is known as the minimum transport condition (MTC). Here, we investigate the effect both of sand concentration and particle diameter on MTC in a horizontal pipeline in the stratified flow regime. Non-intrusive conductivity probes were utilised for the detection of sand. These sensors are commonly used for the measurement of film thickness in gas and liquid flows, but we demonstrate their use here for sand detection after suitable calibration. It was observed that at the ultra-low sand concentrations of our experiments, MTC increases with both sand particle diameter and concentration. We developed a new correlation based on Thomas's lower model but included a sand concentration correction term that also applies at low particle concentrations. The correlation's predictions compared favourably with our measurements at MTC as well as data obtained from the open literature at medium concentrations.

Isolation of aflatoxin producing species of Aspergillus from foodstuffs sold in calabar markets, Cross River State, Nigeria

Abstract: The isolation of aflatoxin producing species of Aspergillus from foodstuffs sold in calabar market was investigated. A total of eight food samples were bought from markets within Calabar. The samples were separately analysed for the presence of aflatoxin producing species of Aspergillus. The isolation of these species was carried out using dilution plating and direct plating methods respectively. Altogether thirteen species of moulds belonging to three genera were isolated from these samples. The most predominant genus-Aspergillus accounted for ten species, while Penicillium accounted for two species and Rhizopus accounted for one species. The aflatoxin producing species of Aspergillus, A. flavus was isolated from six food samples (peanuts, rice, groundnuts, wheat, maize and flour) while A. parasiticus was isolated from four food samples (peanuts, rice maize and groundnuts). However, there were variations in the degree of occurrence of each of the two species in each of these samples. Key Words: Aflatoxin, Aspergillus species, food stuffs.

Evaluation of Kidney Function Parameters in Diabetic Rats Following Virgin Coconut Oil Diet.

Abstract: BACKGROUND Diabetes mellitus (DM) leads to disruption of kidney function parameters (KFPs) which are markers of kidney diseases, especially nephropathy. Virgin coconut oil (VCO) has been implicated in playing a significant role in DM management. However, its role on KFPs in DM is scarce. AIM To evaluate the kidney function parameters following VCO diet in diabetic rats. MATERIALS AND METHODS Twenty-five (25) male rats of 150 - 200 g were divided into 5 groups (n=5): Non-diabetic control (Group 1), diabetes control (Group 2), diabetes + metformin (Group 3), diabetes + 10% VCO (Group 4) and diabetes + 20% VCO (Group 5). Apart from Group 1, other groups were given intraperitone-ally 50 mg/kg of streptozotocin to induce diabetes mellitus. After 72 hours, fasting hyperglycaemia was confirmed by glucose oxidase method. All the rats were fed normal rat chow for 8 weeks. At 8th week, serum and urine samples were analysed for biochemical analysis. After 8 weeks, Group 1 and Group 2 continued to be fed on normal rat chow while other groups were treated with diets (VCO) or drug (metformin) for 4 weeks. At 12th week, urine samples were collected for biochemical analysis, the rats were sacrificed, and blood samples were collected by cardiac puncture. RESULTS There were significant differences in some KFPs in diabetes control (Group 2) compared to other experimental groups. However, there was no significant difference in glomerular filtration rate (GFR) and serum sodium in all the groups. CONCLUSION VCO supplementary diet improved the altered KFPs and could be a therapy for kidney problems.
