Published: February 2024

Background: Hypertension is the largest contributor to global burden of disease with uncontrolled hypertension rising from 600million to nearly 1billion. Nigeria, as the most populous country in Africa, is not immune to the trend of global health and is even more vulnerable considering her population growth rate and lifestyle challenges. This study therefore aims to identify the prevalence of high blood pressure in the semi-urban community in southern Nigeria. Methods: 199 subjects participated in this community-based cross-sectional descriptive study conducted among adults age ≥18 years in an outreach held by GoodHeart and life support initiative in November 2023 at Rumuomasi community in Obio/Akpor Local Government Area in Port Harcourt Rivers state, Nigeria. Biodata was collected and blood pressure was measured using a mercury sphygmomanometer. Results: Of the 199 subjects that participated in this study, 63 (31.66%) were males and 136 (68.34%) females with a mean age of 48.5 ± 14.33 years. The prevalence of high blood pressure in the study population stands at 71.86% (n = 143). Among the hypertensive, 100 were females and 43 males. Early detection and treatment are crucial and should be encouraged, especially in an environment where ignorance and poverty hinder proper health-seeking behavior.
Beyond rewards and punishments: enhancing children's intrinsic motivation through self-determination theory
Authors: Guo Nyuhuan
Published: February 2024

In the domain of educational psychology, the cultivation of intrinsic motivation within children presents a pivotal challenge, especially when considering the limitations inherent in conventional reward and punishment systems. This research delves into the efficacy of Self-Determination Theory (SDT) as a transformative approach to foster intrinsic motivation, transcending traditional methods by emphasizing autonomy, competence, and relatedness. The study systematically reviews existing literature and employs theoretical analysis to construct a comprehensive methodological framework aimed at enhancing intrinsic motivation through educational practices rooted in SDT. The core of SDT posits that satisfying the psychological needs for autonomy (self-governance and freedom in learning), competence (mastery and effectiveness in tasks), and relatedness (meaningful social connections) can significantly bolster the intrinsic motivation of learners. By aligning educational strategies with these fundamental psychological needs, this research hypothesizes that learners will not only exhibit a heightened state of internal motivation but also demonstrate improved learning attitudes and behaviors. The findings from this study provide empirical support for the superior efficacy of SDT-based strategies over traditional reward and punishment approaches. Specifically, the application of SDT in educational settings has shown to markedly enhance children's intrinsic motivation, thereby fostering a more engaging and effective learning environment. This shift not only promotes a deeper, more self-driven engagement with learning material but also cultivates a positive outlook towards education, setting the stage for lifelong learning. In conclusion, the research underscores the significant potential of SDT to redefine motivational strategies within educational paradigms, offering a robust alternative to traditional methods by effectively nurturing the internal drive to learn among children.

Published: February 2024

Environmental toxicants have been linked to female reproductive dysfunction resulting from oxidative stress. The study assesses the impact of ethanolic leaf extract of Annona muricata (EAM) on ovarian and uterine function following mercury-induced toxicity in female Wistar rats. The study involved 40 female Wistar rats, each weighing 114–156g, divided into eight groups of five animals each. Group A received feed and water only; group B received 500 mg/kg of EAM only; and group C received 25 mg/kg of mercury chloride (HgCl2). Groups D and E received 100 mg/kg and 500 mg/kg of EAM for 4 weeks and were treated with 25 mg/kg of HgCl2, respectively. Group F received 500 mg/kg of EAM for 4 weeks and treated immediately with co-administrstion of 25 mg/kg of HgCl2 and 500 mg/kg of EAM for 4 weeks. Groups G and H received 25 mg/kg of HgCl2 and received 100 mg/kg and 500 mg/kg of EAM for 4 weeks, respectively. Progesterone amd Estrogen levels were measured at the end of the administration. The data was analysed using SPSS version 25, with inferential statistics performed, and significant values were set at p≤0.05. Administration of mercury resulted in a decreased level of estrogen, and progesterone. EAM treatments resulted in statistically significant increased levels of progesteron in groups E, F, G and H; group D also showed an increase, though not statistically significant. Estrogen levels were increased in groups F, G and H, but groups D and E showed a decrease in estrogen levels, though not statistically significant. The study reveals that EAM enhances female reproductive hormonal levels and may turn out into a potential capable of reversing or preventing female infertility linked to mercury chloride toxicity.

Published: February 2024

As transformer does not have any rotating parts hence it is called as static device, therefore it does not have mechanical losses, but internal stresses arose from abnormal system conditions like Over currents due to overloading on Transformer and short circuits, The faults can cause mechanical and thermal stresses inside the transformer winding and its connecting terminals. Thus transformer must be protected from above stresses. The aim of this project is to obtain real time data of transformer from remote places with the help of Internet of Things[ IOT] and then designing and implementing a Global system of Mobile communication [GSM] based technology to measure overvoltage, load current, and winding temperature. By measuring the condition of Transformer will help us to point out an any abnormalities before any serious damage that in turn leads to a greater credibility and significant cost savings
The impact of education on income inequality: A comparative analysis of Nigeria and South Africa
Authors: TONIMI ROTIMI-OJO
Published: February 2024

Nigeria is plagued with the problem of poverty, and this is exacerbated by the problem of income inequality. Inequality has also limited the opportunities of individuals in Nigeria as Valentine (1968) said that “the essence of poverty is inequality; in slightly different words the meaning of poverty can be said to be deprivation”. The Gini coefficient of Nigeria lies between 40 and 60% (Bakare A.S, 2012). Also, South Africa has one of the worst cases of income inequality in the World, As South Africa’s Gini index increased from 0.64 in 1995 to 0.69 in the year 2005 which is one of the highest in the world. Studies will be carried out on both countries to further understanding on the relationship between income inequality and Education. With the aid of descriptive and empirical analysis, this study aims at identifying factors that are responsible for the high levels of income inequality, with a focus on Education growth in Nigeria and South Africa. Both countries will be compared using time series data spanning from 1981 to 2016. The study examines the effect of education on income inequality in Nigeria and South Africa and examines if a long-run relationship exists between education and income inequality in Nigeria and South Africa. The Johansen Cointegration and Vector Error Correction Model were applied. The result of the Johansen Cointegration shows that there is a long-run relationship between the independent variables –Inflation, Real Gross Domestic Product, Foreign Direct Investment and Primary School Enrollment rate in Nigeria and South Africa. Findings also attest to the impact of education on income inequality in Nigeria but not in South Africa as further research showed that the income inequality situation in South Africa was connected to racial segregation. It was concluded that the government should devote more attention to this dwindling sector so as to reduce the income gap in the Country.

Authors: Rumihin Ony Frengky
Published: February 2024

This article explores the evolving concept of water governance across various nations, serving as a reference for effective and sustainable water management. Aligned with Sustainable Development Goal (SDG) No. 6, which focuses on Clean Water and Sanitation, Indonesia faces unique challenges due to its dual climate patterns of rainy and dry seasons. These climatic variations necessitate sound water resource management to address water shortages during droughts, prevent drought-related disasters and mitigate flood risks during the rainy season. Utilizing a literature review methodology, this research aims to comprehend the development of knowledge in the water governance concept, incorporating both technical and political dimensions in policy formulation. The findings underscore the significance of collaboration, cooperation, and participation among the government, community, and private sector in implementing effective water governance. Embracing the governance paradigm, the key takeaway is the need for collective efforts to establish robust water resource management, thereby ensuring the success of the clean water and sanitation program nationwide by 2030. However, it is crucial to acknowledge that not all variants of water governance models can be universally applied, considering the diverse institutional contexts and political cultures across different regions in Indonesia. Despite these challenges, this research underscores the importance of a holistic approach that integrates both technical and political aspects in water management policies, providing a foundation for achieving sustainable water access and sanitation goals.

The increasing population and the socio-economic level of the community increase the amount of waste from day to day. Dangerous and poisonous (B3) waste is no exception. Not many people know that household waste also contains many types of B3 waste. Household B3 waste is a type of waste that contains hazardous, toxic, and explosive substances as the remains of daily household activities. The need for household B3 waste management is due to decreasing its adverse impacts on environmental and human health. Most people in rural areas still dispose of B3 and non-B3 waste without sorting. This socialization activity aimed to Ðµducate the partner community, The RÐµmbang VillagÐµ of Ngadiluwih District community, regarding B3 wastÐµ and its management. The action included prÐµparation, community approach, survey, and socialization. Participants wereÂ enthusiastic, and the program raised their awareness and improved their skills and knowledge in waste management.Â Seiring meningkatnyaÂ  penambahan penduduk serta aktifitasÂ  dan tingkat sosial ekonomiÂ  masyarakat memicuÂ  terjadinyaÂ  peningkatan jumlah sampah dari hari ke hari, tidak terkecuali sampah B3.

Published: February 2024

The composition of the growing medium and the application of moringa leaves liquid organic fertilizer (LOF) were investigated based on studies on the growth and yield of bok choy in Gondang Village, Plosoklaten District, Kediri Regency. The research was conducted for three months, from May to July 2022. The experiment was carried out in a factorial complete randomized design. The first treatment, namely: the composition of the planting medium, consisted of 3 levels with a ratio of soil to burned husk, respectively: 50, 30, and 10%. The second treatment consisted of LOF concentrations of moringa leaves at three levels: 10, 15, and 20ml per litre of water. Parameters observed within the scope of bok choy growth were plant height, number of leaves, and leaf area, while yield parameters were represented by fresh plant weight. Observation data were processed and analyzed based on variance tests. If the treatment affected the outcome significantly, additional tests with an LSD of 5% were performed. The study showed no interaction effect of the treatment of the composition of the planting medium with the LOF concentration of moringa leaves on all research parameters. The impact of the treatment on the composition of the growing media has a separate effect on the parameters of the number of leaves, leaf area, and plant fresh weight. Treatment of 50% M1 planting media composition gave the best results for each parameter.Â Komposisi media tanam dan aplikasi pupuk organik cair pada daun kelor diteliti berdasarkan kajian pertumbuhan dan hasil tanaman sawi.

Shallot is the primary commodity for most farmers in Sukorejo Village Nganjuk Regency. The shallot planting system must be optimized to produce optimal products. This study aimed to determine the income of shallot farmers using mulch and non-mulch systems. The determination of the sample was stratified random sampling. Two categories of shallot farmers were identified as mulch system users and non-users. Analysis results showed that both categories simultaneously affected income. The mulch users gained an income of IDR 204,929,703, while non-mulch users earned IDR 267,901,111. Therefore, the income of farmers using a non-mulch system was greater than that of farmers using a mulch system. In conclusion, the absence of a mulch system helps farmers save more on production costs. The mulching system users require to pay more attention and extra care on the utilization to reduce maintenance costs.Â Bawang Merah merupakan komoditi utama bagi mayoritas petani pada daerah penelitian. Sistem penanaman bawang merah harus bisa dioptimalkan agar menghasilkan produk yang optimal juga.

Okra fruit (Abelmoschus esculentus L.) is a vegetable that is often used as medicine. Okra fruit contains flavonoids which are antioxidants. Gel formulation with a concentration of 5%, and various combinations of HPMC and carbopol bases. This research aims to determine the physical stability of gel preparations and the effect of variations in the concentration of gelling ingredients in the preparations. The gel formulation consists of 4 formulas, namely F0, F1, F2, and F3. Physical stability tests include organoleptic tests (odor, color and texture), homogeneity, pH, spreadability, stickiness, viscosity and synergy. Tests were carried out for 14 days of storage, namely on days 1, 3, 5, 7, and 14 at room temperature (25℃). The observation results showed that in the organoleptic test there was no change in color, odor and texture in the gel preparation during 14 days of storage. The four gel formulas are homogeneous and there is no synergy. Variations in the combination of HPMC and carbopol bases affect the physical properties of the gel, including pH, viscosity, spreadability and adhesion. HPMC and Carbopol affect the pH of the preparation, the higher the Carbopol content and the lower the HPMC content, the more acidic it is. Carbopol and HPMC affect the values of spreadability, viscosity and adhesion because the higher the concentration of carbopol and HPMC produces a thick gel preparation so that the spreadability decreases, viscosity increases and adhesion also increases.

The amount of Remaining Operation Results (ROR) obtained by Koperasi can reflect the health ofits financial management. Many economic factors can affect the ROR of Koperasi itself. This studyaims to determine the economic factors that significantly influence ROR based on a statistical model ofmultiple linear regression. The novelty of this research provides new analytical results that compare themost three influential factors based on previous research to show the factors significantly influencingthe ROR. The quantitative data used the five years financial statements of Koperasi Sawit Makmur in2017-2021 consists of 20 data on liabilities, net worth, assets, and ROR of Koperasi Sawit Makmur. Theresults show that asset variable as an excluded variable that does not affect the ROR of Koperasi withR2 = 0, 961. Liabilities and net worth variables can explain 96.1% of ROR, with 3.9% can be explainedby assets and other variables not included in the study. Liabilities have a negative and tangible effect,and net worth has a positive and partially real influence on ROR. The factor with the most dominantinfluence on ROR is net worth, with an influence percentage of 63,80%. The future research is expectedto provide an overview of net worth and asset determinants using related statistical methods.

С помощью современных методов молекулярного моделирования определены значения - f H(TS1,MEAN) = 770,7± 16,8кДж/моль, S(TS1,CORR)IRot = 808,9Дж/(моль·К) для переходного состояния, образующегося в реакции п-PhC(O 2• )HPhOH с п-PhCH2PhOH (п-бензилфенолом) и ведущей к образованию п-PhC(O2H)HPhOH (п-бензиленгидропероксидфенола). Рассчитана температурная зависимость константы скорости этой реакции (kT =1,8· 10-16 (T/298,15)4,17 e -35752/(RT ) см3/(молек.·с)). На основании анализа термохимии и констант скорости этой и схожих с ней реакций сделано предположение, что ее протекание осуществляется в две стадии: (1) перенос атома H; (2) последующая безбарьерная структурная реорганизация радикала. Рассчитанная температурная зависимость kT позволила также оценить возможные длины цепей и скорости реакций, а также обрисовать приемлемые температуры для получения п-бензиленгидропероксидфенола.

Рассмотрены некоторые особенности проведения измерений параметров воздушных ударных волн (УВ) путем анализа последовательных кадров скоростной видеосъемки. Авторы обращают внимание на возможный источник погрешности в определении скорости УВ, возникающий вследствие затенения фронта УВ в плоскости съемки. Затенение происходит из-за искажений, возникающих при изменении коэффициента преломления воздуха при прохождении УВ в зоне между камерой и плоскостью съемки. Путем простых геометрических выкладок показано, что ошибка измерения скорости фронта УВ может достигать 33% в зависимости от типа используемого объектива в диапазоне наиболее типичных расстояний съемки при взрывном эксперименте. Даны рекомендации по выбору объектива и оценке эффективного расстояния при съемке взрыва и последующего определения параметров УВ. Предложен способ индикации (коррекции) возникающей ошибки при помощи лазерных маркеров, размещенных на взрывном поле и создающих несколько реперных точек для последующей компенсации искажений изображения при его цифровой обработке.
