CONSUMPTION

This study aimed to design and implement a low-cost microcontroller-based system for monitoring the energy consumption of individual workshop machines, addressing the limitations of conventional centralized metering systems that fail to provide machine- specific data. The literature review examined previous work on energy monitoring technologies, including commercial, open-source, and academic systems, highlighting the growing role of the Internet of Things (IoT) in enabling real-time data acquisition and remote monitoring. It emphasized the need for affordable, scalable, and educationally adaptable solutions for developing regions, where technical expertise and financial resources are limited. The research adopted an experimental design methodology involving hardware and software integration. The system was built using Arduino Nano and ESP32 microcontrollers, ZMPT101B voltage and SCT-013 current sensors, an LCD display, and a ThingSpeak IoT cloud interface. Mathematical modeling was applied to compute voltage, current, power, energy, and cost, while SolidWorks was used for casing design. Calibration and testing were conducted under varying load conditions to assess accuracy, response time, and data stability. Data were logged both locally on an SD card and remotely on the cloud for redundancy and analysis. Results indicated that the system achieved high accuracy within ±1% for voltage and ±5% for current, with an overall efficiency of 95% and IoT data transfer uptime of 98%. The developed prototype successfully provided real-time monitoring, stable performance, and reliable data transmission. The study concluded that the Arduino-based energy monitoring system is a cost-effective, scalable, and efficient solution suitable for educational, domestic,v and small-scale industrial applications. It recommended future enhancements in predictive analytics, multi-machine scalability, and integration with renewable energy management platforms.

Climate change has become a significant global threat in the 21st century. This has led to various crises, including irregular precipitation patterns, flooding, melting ice caps, and droughts. These changes are driven by both natural factors and human activities such as greenhouse gas emissions, changes in Earth’s orbit, fossil fuel combustion, and tectonic movements. One of the most critical impacts of climate change is the water supply crisis. This study aim to assess how climate change influences the sustainability of water supply in Agenebode. Data was collected by distribution of one hundred and fifty hard-copy Likert-scale questionnaires to respondents and analyzed using descriptive and correlation statistics through the use of Statistical Package for Social Sciences (SPSS). The result shows that there is minimal vulnerability of water supply to climate change, the people do not behave in a way to cope with the impact of climate change, socioeconomic and cultural factor have less influence on domestic water consumption patterns and sustainability and there is little challenges in implementing sustainable water management practices. Therefore, it is seen that the people in the study area have minimal challenges in sustaining domestic water supply in a changing climate. it is recommended that the promotion of climate-resilient infrastructure capable of withstanding floods and droughts is essential for sustainable water management in vulnerable communities

This study examines the impact of petroleum subsidy on the consumption of petroleum products in Nigeria from 2000 to 2020 using an Error Correction Model (ECM). The analysis reveals that petroleum subsidies significantly stimulate consumption by enhancing affordability. Surprisingly, higher inflation rates are associated with increased petroleum consumption, challenging conventional economic theory which predicts reduced consumption due to diminished purchasing power. Conversely, the relationship between petroleum prices and consumption is weak and statistically insignificant, suggesting that factors beyond price influence consumer behavior. Additionally, higher Gross Domestic Product (GDP) per Capita is unexpectedly associated with decreased petroleum consumption, indicating the presence of other influential factors independent of income levels. These findings underscore the complexity of the factors influencing petroleum consumption in Nigeria and highlight the need for evidence-based policymaking. Recommendations include conducting a comprehensive review of subsidy programs, investing in renewable energy, pursuing economic diversification, managing inflation, and strengthening data-driven decision-making to promote sustainable and resilient petroleum consumption patterns while fostering inclusive economic growth and development.

This study examined sustainable food consumption as correlates of civil servant healthy living in Ekiti State. Seven (7) research questions were raised while five null hypotheses were formulated and tested at 0.05 level of significance. The correlational survey research design was employed for this study. The population for the study comprised of 3,592,000 civil servants in Ekiti State. A sample size of 399 civil servant from the three senatorial districts in Ekiti State were selected to participates in the study, using a multistage sampling technique. The questionnaire titled “Sustainable food consumption and Healthy Living among Civil Servant Questionnaire” (SEHLCSQ) was developed to elicit information from the respondents. The instrument contained 45 items with a 4- point rating scale made up of four response options of Strongly Agree (SA)=(4), Agree (A)=(3), Disagree (D)=(2) and Strongly Disagree (SD)=(1). The instrument was subjected to content and face validity by the researcher’s supervisor and one expert in the department of Vocational and Technical Education and an expert in Psychometrics. A reliability of 0.79 was obtained meaning instrument was high in terms of internal consistency. The researcher directly administered SEHLCSQ to the respondents with the aid of six research assistants. The data collected were analyzed using mean, standard deviation, and independent samples t-test. The null hypothesis 1 was tested using Pearson’s Product- Moment Correlation (PPMC), the null hypotheses 2–4 was tested using independent t-test statistics, while null hypothesis 5 was tested using one-way Analysis of Variance (ANOVA).

Recently, social attitude toward the use of marijuana has changed and some have been advocating for legalization of its use. In the same vein, there has been an increasing interest relating to the health risk associated with it and how it affects several organs in the human body including the liver which is a key metabolic organ of the body. The aim of this study was to determine the possible effects of marijuana consumption on liver function parameters. Sixty adult marijuana smokers and 60 age-matched non-marijuana/cigarette smokers were recruited in the study. Socio-demographic data were collected using structured questionnaire. Serum aspartate amino transferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), total protein (TP) and albumin were determined by spectrophotometric method. Data were compared using appropriate statistical tool. The results indicate that AST(42.4±8.67),ALT (41.67±14.15)andGGT (29.56±8.48) activities were significantly higher (p<0.05) in marijuana smokers than in nonsmokers (26.34±4.95 24.00±5.97, 14.91±3.36) respectively. Conversely, total protein and albumin concentrations were significantly lower (p<0.05) in marijuana smokers than non- smokers. Serum ALP activity was however not significantly different when compared with controls. Some 48/60 (80%) of marijuana smokers had AST values (44.8±8.44) above the upper limit of the reference range while 34/60 (56.7%) had GGT values (61.3±7.60) above upper limit of the reference range. Marijuana consumption may predispose individuals to liver injury independent of quantity consumed and duration of use therefore the public should aware of the liver health risk associated with marijuana consumption.
