The application of good electrical earthing system is inevitable in every electrical installation. This study was carried out to evaluate the earth’s electrical properties of an undeveloped area of Delta State University of Science and Technology, Ozoro, Nigeria. The soil resistance of the study area was determined according to Wenner Four Point method, while the soil resistivity was calculated from the soil resistance obtained. Six locations (A, B, C, D, E and F) were tested across the area; while five probe distances (3 m, 6 m, 9 m, 12 m and 15 m) were adopted at each testing location. Results obtained from the soil test revealed that, the soil resistance and resistivity varied widely across the study area. It was observed that the northern part of the area generally had lower soil resistance and resistivity than the southern part of the study area. The soil resistance ranged between 3.2 Ω and 4.8 Ω at the northern part of the study area; while the soil resistance ranged between 5.1 Ω and 17.2 Ω at the southern part of the study area. In term of the soil resistivity, the results revealed that the northern part of the area had the lowest soil resistivity, compared to the southern part of the area. The soil resistivity ranged from 96.15 Ωm to 324.25 Ωm at the southern region of the area, while at the northern region of the area, the soil resistivity ranged from 60.33 Ωm to 90.49 Ωm. Furthermore, the result established that the northern region of the study area will be suitable for electrical earthing without any soil treatment.

College students can make inappropriate food choices owing to a lack of nutritional knowledge and understanding of dietary requirements. Increasing physical inactivity among college students is also a serious public health problem. To assess dietary habits and physical exercise among nursing students in Riyadh, Saudi Arabia. In 2018, this cross-sectional descriptive study was conducted at a single college in Riyadh, Saudi Arabia, with a convenience sample of 104 level-4—or second year—undergraduate nursing students. Data were collected using a three-part self-assessment questionnaire. More than one-third of the students were overweight; two-thirds consumed unhealthy snacks, and most failed to drink enough water and were physically inactive. The prevalence of overweight and obesity suggests the significance of frequent educational campaigns and seminars on healthy eating and physical activity. Also, further research is needed to assess college students’ knowledge and attitudes about healthy diet and the importance of regular physical exercise.

The aim of this study is to investigate the actual causes of earth tremors in Central Nigeria using geophysical technique. Since 1933 till date (over 88 years), small to moderate magnitude earthquakes have either been observed or instrumentally recorded in Nigeria. However, the specific causes of the intra plate earthquakes in Nigeria is still not well known. In this study therefore, a high-resolution aeromagnetic data analysis was performed to evaluate the various theories proposed as the causes of tremor activity in central Nigeria with a view to ascertaining the actual causes of earthquakes in the West African country that lies on a stable crust. The total magnetic intensity data acquired from the Nigerian Geological Survey Agency (NGSA) in the Central Basement complex of Nigeria, was processed and filtered using the tilt derivative, lineament analysis, and advanced Analytic Signal- Hilbert Solution filter. To define the trends of both major and minor structure, a lineament plot was extracted and plotted. The analysis revealed a dominant NE-SW and NW-SE trending structure that is distributed throughout the study area. The regional North Atlantic Romanche fault system, which extends from the offshore (Niger Delta) into the continental crust, was mapped and is thought to extend from Gwagwalada in the study area's south, through Gwarinpa and Mpape, to Kwoi, and beyond Kafanchan.Findings from our study have indicated that, areas prone to Earth tremors are linked to the Romanche fault by numerous NE-SW and NW-SE faults that act as conduits for seismic energy that causes tremor. Using lineament density analysis, tremor active areas have been interpreted to be highly deformed; thus, seismic energy induced into the environment would result in tremors. This study demonstrates that the regional North Atlantic Romanche fault system is the primary source of seismic energy that causes the earth tremors in central Nigeria.

Introduction: Unwanted pregnancy and unsafe abortion have become serious public health concerns around the world, particularly among female students in both developed and developing countries. The general objective of this study was to investigate the utilization of emergency contraception among final-year female students of a public university in Ghana.

Methods: A stratified random sample was used to enroll 199 female university students for descriptive cross-sectional research. SPSS version 25 was used to analyze the data. To compare categorical variables, Chi-square analysis was employed, and a p-value of 0.05 was considered statistically significant.

Results: Majority (88.4%) of the respondents demonstrated sufficient knowledge, and 84.4% had a favorable attitude towards emergency contraceptives (ECs). On the indications for EC; after unprotected sex (65.3%), after a missed period (22.6%), when one is raped (83.4%), unwanted pregnancy (75.9%), and rupture of condoms (88.9%) were identified. The majority (59.3%) of students have used EC, with most of the students (43.7%) using Postinor-2.  The overall attitude towards EC and Residence (X2=7.5; p=0.023), Religion (X2=6.2; p=0.042), and marital status (X2=17.1, p=0.001) were statistically significant. There was a significant association between the use of EC and Residence (X2=10.9; p=0.004) and marital status (X2=8.6; p=0.035). 

Conclusion: The findings of this study indicated that students had a high level of knowledge and favourable attitude towards EC, with a significant number of the respondents likely to utilize it in the future. This may aid in the treatment of female students' sexual and reproductive health issues and prevent dropping out of school as a result of unwanted pregnancy. Also, there is the need to engage opinion leaders to address their concerns to allow for the effective utilization of emergency contraceptives.

The study was conducted on a sample of 70 deaf children, chronologically aged from 10 to 18 years. Letters of deaf respondents on topics of their choice were used as a measurement instrument. The goals of the research are: To examine the homogeneity of variance of content understanding of written form of expression based on measurements of applied language constructions and content within language discourse, and to determine the statistical significance of content understanding of written form of expression using language constructions within language discourse. The second goal of the study was to examine the connection of language constructions in the applied measurement space of the number of used written expressions in the content understanding of written communication, and to determine the statistical significance of the connection of language constructions in the number of used written expressions in content understanding of written communication. The results of the research showed that the deaf population is characteristic and homogeneous in the way, style of writing and content understanding of the written text observed through linguistic discourse in written dialogue. In the written form of exchange of communication content, a significant degree of communication competence has been achieved, or the comprehensibility of the written form of expression in terms of content understanding. Deaf persons achieve very modest linguistic competence. The reduced ability of deaf children to achieve linguistic competence is reflected through the simplicity of statements in the substantive sense of preferring statements, as one of the characteristics of the linguistic competence of the deaf population.
