The study involved the determination of some physiochemical and bacteriological properties in sachet-water samples taken within selected geopolitical wards in Jere and Maiduguri Metropolis. The purpose was to ascertain the quality of sachet water sold for consumption within the area. Ten samples were drawn, five from each study area. The samples were analysed for temperature, colour, turbidity, pH, conductivity, iron, total alkalinity and total dissolved solid. Bacteriological analysis was also carried out using multiple tube (most probable number) technique for enumeration of both total coliform count and differential Escherichia coli count. Other physical examination like volume, National Agency for Food and Drugs Administration and Control (NAFDAC) registration number, batch number, production date and expiry date were also examined. The results obtained were compared with World Health Organization (WHO), NAFDAC and Nigeria Standard of Drinking Water Quality (NSDWQ). Variations were observed among the entire samples in comparison with the standard. Some of the parameters conform to the standard like the Tempreture, pH, colour, odour, iron content and NAFDAC registration number while others like TDS, total alkalinity and volumetric quantity fell below the standard. The bacteriological analysis also showed that 80% of the samples studied revealed the presence of coliforms. Hence, there is need for regulatory agencies like NAFDAC and Standard Organisation of Nigeria (SON) to intensify effort in the routine monitoring of quality of sachet water marketed for consumption.

A proper assessment of the rate of unsustainable consumption of biomass fuel is important to determine the extent of the consequent environmental effects. In this paper, an evaluation was made of the rate of fuelwood (firewood and charcoal) consumption in Maiduguri metropolis, the capital of Borno state in Nigeria. Firewood and charcoal are the main solid biomass fuels consumed in Maiduguri city, in addition to rarely used animal dung, thatch, leaves, etc. These fuels are usually used in households, markets and industries for cooking, roasting and bakery activities. To quantify the rate of consumption of these fuels in Maiduguri (and their eventual negative effects), data were collected on the rate of supply of the biomass along highways leading to the city. The result shows a total consumption rate of 366 t/day of solid biomass fuel, with firewood accounting for 288 t/day and charcoal makes up the remaining 78 t/day. This fuelwood consumption rate is around 0.15% of the national figure. The resulting emissions of CO 2 , CH 4 , N 2 O, SO 2 , NOx, NMVOC, CO,

1.1. Background: Worldwide Road traffic accident (RTA) is a huge public health and development problems killing nearly 1.2 million people a year and injuring or disabling between 20-50 million people worldwide; thus making the loss of US 518 billion dollars globally. According to World Health Organization, every day more than 3000 people die from road traffic accidents. Developing countries account for 90% of global road traffic deaths. Road traffic accidents are being the critical public health problem that causes disabilities and death in Nigeria which could need due investigations. Therefore, the aim of this study was to determine the Prevalence of Road Traffic Accident and Associated Risk Factors among Drivers in Bauchi State, Nigeria.1.2. Methods: cross-sectional study design was conducted among drivers in Bauchi State, Nigeria from December, 2020 to January, 2021. Data was collected using a pretested structured questionnaire. Descriptive analysis was performed to obtain the frequency distribution of the variables. Results:The result shows that 300 participants responded to the questionnaire. The overall road traffic accident prevalence was 115 (38.3%). Conclusion:The prevalence of road traffic accident revealed in this study is of public health significance. RTA-related causalities are extremely high in Nigeria. Male young adults and vulnerable road users are at increased risk of RTA. The most perceived cause of road traffic accidents mentioned was an overcrowded road which is shared by drivers, pedestrians, and animals. There-fore, there is an urgent need for bringing road safety to the country's public health agenda. AIDS, tuberculosis and diarrhoeal diseases [9] and the deaths due to RTAs are predicted to become the fifth-leading cause of death

Influence is a primary social mechanism through which a leader enacts his or her leadership using various tactics to influence others. This study is an attempt to investigate the effect of influence tactics on worker’s performance in Dangote Cement Plc, Obajana- Kogi State. Specifically, it was designed to examine the effect of appeal to higher authority; ingratiation; impression management; and persuasion tactics (as the dependent variables) on workers performance. A descriptive-survey research design was adopted, while purposive sampling technique was employed to arrive at a sample size of fifty-eight (58) from the research population of 151 senior staff, frontline managers and management personnel of the organization. Out of the fifty-eight questionnaires administered to the staff, only forty-eight were returned. Multiple regression analysis was used to determine the relationship between the two variables using the regression coefficients (Beta values). Results showed that ingratiation has a negative and insignificant effect on performance; impression management have positive and insignificant effect on workers performance; but appeal to higher authority and persuasion tactics had positive effect on workers performance in Dangote Cement Plc, Obajana- Kogi State. The study recommended that management of the firm should adopt the use of persuasion and appeal to higher authority considering their positive effect on workers performance; the use of ingratiation as an influence tactics should be minimized; and impression management should be encouraged.
