Digital eye strain is a public health problem. It is the number one occupational hazard of the 21st century. It causes considerable reduction in productivity in working environment. In today’s world, the use of smartphone is a necessity for majority of people, but not many of them consider the medical consequences of using smartphones.15 The aim of this work was to assess the knowledge, attitude and prevention practices on the use of mobile phone light among ABU students. A cross-sectional study was conducted in May, 2023 using a multi-stage sampling method to select 153 students of ABU, Zaria, Kaduna State, Nigeria. Data were collected with the aid of an adapted, pre-tested, structured, self-administered questionnaire. The data collected were analysed using SPSS and Microsoft excel statistical software. The results were presented in frequency tables. The Chi-square test was used to assess the associations between categorical variables. The level of significance was set at <5% Up to 61.4% of the respondents were within the age group 21 and 25 years. A total of 75.8% of the respondents had good knowledge of digital eye strain, with a mean score of 1.71. Another 66% of the respondents followed healthy practices regarding digital eye strain, with a mean score of 0.66. However, the attitude was negative among majority of the respondents, as only 34% of the respondents had positive attitude towards digital eye strain. The study indicates that despite the good level of knowledge and healthy practices regarding digital eye strain among ABU students, majority of them still have negative attitude towards digital eye strain. Educational strategies to raise awareness on digital eye strain were recommended.

HBV is one of the most prevalent and a serious Global public Health problem, affecting more than 2 billion people Worldwide with more than 350 million people approximately infected with chronic infection. Hepatitis B (HBV), hepatitis C (HCV), and human immunodeficiency virus (HIV) are the three main blood-borne infections associated with occupational exposure in the health-care and laboratory setting and remain a significant burden to HCW. This study aimed to assess the Knowledge, attitude and practices of HBV PEP among Health Workers of ABUTH, Shika, Zaria.

This study investigates the perceptions of crop farmers in Sabon Gari Local Government Area, Kaduna State, regarding the impact of digital technology on agricultural productivity and income. With the rapid advancement of digital tools in agriculture, including precision farming, mobile applications, and digital marketplaces, the potential for enhancing productivity and income has never been greater. However, challenges such as limited infrastructure, digital literacy, and cost barriers continue to impede widespread adoption. A structured questionnaire was used to collect data from 148 crop farmers, assessing their awareness, adoption, and perceived impacts of digital technology on farming practices. The study reveals that while many farmers recognize the benefits of digital tools in optimizing resources and improving crop yields, adoption remains low due to high costs and limited access to necessary technologies. The findings underscore the need for targeted interventions to improve infrastructure, provide affordable digital tools, and enhance training programs. These measures could help to increase the adoption of digital technology and thereby improve the productivity and income of farmers in the region.

Menstruation is the cyclical discharge of blood, secretions, and tissue debris from the uterus that recurs in nonpregnant breeding-age primate females. Menstrual hygiene and management, in females, is the act of using a clean absorbent material to collect menstrual blood, with adequate privacy to change at any time, use of soap and water for handwashing, as well as disposing used pads safely and conveniently in the environment. The issue of menstrual hygiene among adolescent female students is one that has plagued public health for a long time. This resesrch study aimed to assess the attitude and practice of menstrual hygiene among adolescent females of a secondary school. The study is a cross-sectional design type with a simple random sampling of the probability sampling method used to obtain the sample size. A total population of 543 female secondary students, with a sample size of 230 was used in the study. Data was collected using a structured questionnaire, a response rate of 77.4% (178) was gotten and it was analyzed using the descriptive statistics method. Analysis of the data revealed that female students of Demonstration Secondary School have good knowledge regarding menstrual hygiene, with a 62.8% overall percentage of positive response, good attitude with a positive mean of 3.3, and moderate practice with 71.3% majority score of 4-6 out of 10 identified correct options of practice from the questionnaire distributed. The challenges identified in managing menstruation in school by adolescent females of Demonstration secondary school includes insufficient disposal methods, inadequate availability of soap and water for handwashing, and unsanitary conditions in changing areas. The study recommended that federal and state government bodies develop policies that cater to the reproductive health of the girl child in schools and sanction schools which are found wanting in any aspect of the policy.

This research focused on the modelling and simulation of a liquefied natural gas (LNG) regasification plant using DWSIM software to optimize energy use and improve efficiency. The problem addressed was the energy-intensive nature of LNG regasification and the need for optimizing its processes. The methodology involved developing a process flow diagram using methane as the LNG component and integrating an Organic Rankine Cycle (ORC) for power generation. The system was simulated under varying pressures to analyze its energy consumption. Findings revealed that increasing pressure significantly raises energy demands, with energy consumption for regasification rising from 35,440.2 kW at 60 bar to 98,807.08 kW at 90 bar. The integration of the Organic Rankine Cycle enabled 67,555.3 kW of power generation from waste heat, showcasing the potential for energy recovery. The study concluded that coupling LNG regasification with power generation enhances energy efficiency, and it recommended further optimization of operating pressures, exploration of cold energy recovery technologies, and the minimization of environmental impacts. This research contributes to improving the operational efficiency of LNG regasification plants

This research conducted a comparative analysis of energy generation and cost efficiency using three different fuels—rice husk, LPG, and coal—to assess their suitability for heat generation in cement kiln operations. Two sets of simulations were performed using DWSim software. The first simulation maintained a constant flow rate of 10 kg/h for each fuel. The results revealed that rice husk generated 784.24 kW, LPG produced 2931.26 kW, and coal generated 1275.38 kW of energy. In the second simulation, the mass flow rates were adjusted based on an equivalent energy cost basis of ₦20,000 for each fuel type. The mass flow rates were 1000 kg/h for rice husk, 240.96 kg/h for coal, and 16.67 kg/h for LPG. This yielded heat generation of 1638.53 kW for rice husk, 23,767.6 kW for coal, and 2912.18 kW for LPG. These results indicate that coal provides the highest energy output, followed by LPG and rice husk when considering both simulations. While LPG outperformed rice husk in terms of energy efficiency, rice husk remains a viable and sustainable alternative, especially in Northern Nigeria, where it is readily available. This study highlights the trade-offs between energy efficiency, cost, and environmental sustainability when selecting alternative fuels for cement production.
