Abstract
Climate change presents challenges for both industrialized and developing nations, primarily due to insufficient pollution control. Increased fossil fuel usage escalates pollution levels, emphasizing the need to integrate more renewable energy into the energy mix, particularly to reduce carbon emissions. Consequently, public investment in renewable energy becomes pivotal to enhance the necessary technology for green energy production. Human development and technological progress play a crucial role in advancing green energy and ensuring environmental sustainability. This study addresses whether clean energy and technology can foster ecological sustainability in the G7 while considering human development. Findings emphasize the significance of public investments in renewable energy projects, technical innovation, and human development. Such investments are essential for augmenting renewable energy shares and lowering carbon emissions in the long run. The study proposes relevant policies to help G7 nations achieve United Nations Sustainable Development Goals related to green energy transition (SDG-7), environmental sustainability (SDG-13), and innovation (SDG-9). In essence, prioritizing renewable energy investment and innovation is imperative for sustainable development.

Abstract
Sustainable development aims to both alleviate poverty and protect the environment. Previous research has explored the connection between poverty and carbon emissions. However, in Sub-Saharan Africa, nearly half of the population lives below the international poverty line, hindering economic growth and sustainable development. Therefore, this current study aims to further explore different age groupings of poverty and economic growth relates to environmental pollution, in 43 Sub-Saharan African nations. This study addresses existing gaps by employing the Driscoll-Kraay (D-K) standard error technique and the method of moments quantile regression to examine the connections between variables, yielding significant findings. The results indicate that youth and middle age poverty has an inverse relationship with environmental pollution. In conclusion, this study emphasizes the critical importance of addressing poverty in the formulation of policies aimed at mitigating environmental pollution and promoting sustainable development in Sub-Saharan African countries. Insights from this research can inform policymakers and other stakeholders in designing more effective interventions, programs, and initiatives to combat both poverty and environmental degradation, ultimately leading to a better and more equitable environment.

Abstract
Africa, over the past years, has put various measures in place in the fight against carbon emissions. Achieving net zero carbon has caused the continent researchers to investigate various conditions required for a successful transition. Therefore, the political system cannot be left out since it plays a major role in decision-making. This study contributes to previous literature analyzing the empirical effect of financial development and governance quality on carbon emissions. The study is focused on 52 African countries with data from 1996 to 2021. Panel quantile and generalized method of moments are used for the analysis. The result indicates that financial development contributes to environmental degradation, government effectiveness, rule of law, and political stability which promote environmental pollution; however, control of corruption, renewable energy, and economic growth promote ecological sustainability. According to the aforementioned, it is crucial for governments to include financial development plans in national environmental strategies, particularly for those in African nations. Furthermore, governments should put restrictions on trade to control the trade of high-carbon technologies.

Abstract
In recent years, researchers and politicians have become concerned about the ever-increasing energy consumption of ICT gadgets. Any effort to reduce greenhouse gas emissions should take the ICT industry's carbon emissions into account, given the widespread usage of ICT products across all economic sectors. Employing Driscoll-Kraay Panel Corrected Estimators for E7 economies from 2000 to 2020, we examine the direct impacts of ICT on ecology as well as the indirect implications through connections with the availability of clean fuel and technology for cooking and trade while also adjusting for population and renewable energy. From the empirical findings, it was observed that the two proxies of ICT services (i.e., internet-penetration and mobile-subscriptions) were negatively significantly connected with E7's (Brazil, China, India, Indonesia, Mexico, Russia, and Turkey) carbon emissions. Similarly, access to clean fuel and technologies for cooking and renewable energy decreases emission levels within the E7 economies, while trade openness and population growth increase emission levels within the said economies. Moreover, the method of moment quantile regression used as a robustness check affirms the baseline technique. According to the findings, the E7 economies can safely boost internet usage and associated technologies to lower emissions. They may lessen their negative impact on the ecosystem by increasing the utilization of renewable energy and expanding access to clean fuel and cooking technologies.

Abstract
INTRODUCTION Uterine artery (UtA) Doppler sonography is a potential screening tool for pregnancy complications in placental insufficiency. Evaluation of the maternal and fetal vessels in pregnancy ensures accurate identification and prediction of pregnancy complications, such as preeclampsia (PE) and intrauterine growth restrictions (IUGR). The study aims to establish local reference values for UtA in a Nigerian population. METHODS This prospective longitudinal study was conducted among 230 pregnant women. All participants had their left (Lt) and right (RT) UtAs evaluated with a Doppler ultrasound from 11 to 30 weeks 6 days of gestational age. Peak systolic velocity (PSV), End diastolic Velocity (EDV), Systolic/Diastolic ratio (S/D), Pulsatility Index (PI), and Resistivity Index (RI) were measured and documented. RESULTS The mean values of UtA at 11-30 weeks 6 days of GA ranged as follows: 0.79-0.53 (RI), 1.83-0.79 (PI), 5.16-2.23 (S/D), 96.37-98.00 (PSV) & 26.07-44.14 (EDV). While the mean values of the Rt. & Lt. UtA 's ranged as follows: 0.79-0.50 (RI. Rt), 0.78-0.56 (RI. Lt), 2.05-0.80 (PI. Rt), 1.61-0.78 (PI. Lt), 6.03-2.13 (S/D. Rt), 4.29-2.33 (S/D. Lt), 89.79-99.23 (PSV. Rt), 102.76-96.71 (PSV. Lt) & 23.31-45.25 (EDV. Rt), 28.83-43.02 (EDV. Lt) respectively. CONCLUSION UtA Doppler reference range was established in the study population. These reference ranges will be of clinical value in daily obstetric practice. IMPLICATION FOR PRACTICE Obstetricians and sonographers will apply these values for early prediction of pregnancies at risk of complications in the locality.

Abstract
The BRICS nations are often seen as being at the vanguard of the push to implement sustainable energy technologies, even at the household scale, as part of the transition to sustainable societies. Given that the Sustainable Development Goals (SDGs) are interconnected and that achieving one is a good springboard for achieving others, we see the SDGs as having three dimensions: socio-economic-environmental sustainability. However, energy is central to attaining these tenets in the UN-SDG. Therefore, this work aims to use three germane methods-feasible generalized least square (FGLS), fixed effects model, and quantile regression-to discover empirical evidence to back up these statements. When different econometric estimate methods were used, these findings remained reliable. The research also showed that clean energy is essential when determining strategies to achieve environmental sustainability, human development, and foster green economic growth. Thus, investments in green resources and technological innovation promote the country's transition to sustainable development. They also show a substantial beneficial influence of clean and green energy and technology on supporting the main tenet of UN-SDG in BRICS across most quantiles. As a result of these major analytical findings, some relevant policies are proposed to enable the BRICS countries to achieve some of the United Nations Sustainable Development Goals that are closely related to undergoing green energy transition (SDG-7) and achieving environmental sustainability (SDG-13) through the channel of innovation (SDG-9). The study consequently suggests that to combat climate change, promote green economic growth, and assure human development, which will increase the likelihood of the UN-SDGs, investment in clean energy should be given top priority on the BRICS agenda.

Abstract
INTRODUCTION Radiology equipment requires routine maintenance to prevent equipment breakdown. Equipment breakdown can lead to adverse patient outcomes and lost revenue to hospitals. In Ghana, there is a mismatch between the available radiology equipment and requests which may result in frequent breakdown. Several studies have been conducted to investigate equipment downtime across radiology departments. However, there is none for Ghana. This study therefore investigated the downtimes of radiology equipment across three hospitals in Ghana. METHOD The study covered the period January-December 2020. An inventory sheet was used to collect data on equipment specifications, frequency of breakdown, downtimes, average daily patient throughput, the average cost of common examinations, the availability of post-installation training and maintenance contracts/agreements. RESULTS The study reviewed 32 items of radiology equipment. Radiology equipment across the hospitals broke down frequently and downtimes were very high. Radiographers/radiologists across the hospitals were provided with poor/inadequate post-installation training, and maintenance contracts/agreements were unavailable. The radiology equipment downtimes resulted in significant lost revenue of GH₵ 16,279,803 (US$ 1,968,537). CONCLUSION Radiology equipment across the hospitals broke down frequently and downtimes were lengthy leading to significant lost revenue for the hospitals. Post-installation trainings were poor/inadequate, spanning a few hours. Also, maintenance contracts/agreements were non-existent across the three hospitals. A nationwide study is needed to determine equipment downtimes and lost revenue across all radiology departments in Ghanaian hospitals, to better inform policy-making. IMPLICATIONS FOR PRACTICE This study may help hospital managers and other stakeholders involved in policy formulation and strategic planning, put measures in place to minimise radiology equipment breakdown in Ghana. The study may also help optimise radiology services and enable radiology departments to render uninterrupted clinical services to patients in Ghana.

Abstract
The nations participating in the Belt and Road Initiative (BRI) are particularly vulnerable to the challenges posed by climate change due to their extensive trading activities. The need to protect the environment and mitigate the adverse impacts of climate change in these countries is of utmost importance. Therefore, this study contributes to the scientific understanding of this issue by examining the relationship between trade openness and environmental sustainability in 89 BRI countries from 1990 to 2020. Additionally, control variables, including economic growth, energy consumption, urbanization, industrialization, and foreign direct investment, are considered to address omitted variable bias issues. The study utilizes the Augmented Mean Group (AMG) and Common Correlated Effects Mean Group (CCEMG) regression estimators, and the findings reveal that trade openness improves environmental sustainability. However, economic growth, energy consumption, urbanization, and industrialization degrade environmental sustainability. Interestingly, the results affirm foreign direct investment as a trivial determinant of environmental sustainability. Regarding causal relationships, reciprocal causalities are observed between trade openness and carbon emissions, energy consumption and carbon emissions, and urbanization and carbon emissions. Furthermore, one-way causalities exist from economic growth to carbon emissions and from carbon emissions to foreign direct investment. Nevertheless, no causal relationship is identified between industrialization and carbon emissions. Based on these significant findings, it is recommended that China, as a prominent player in the BRI, takes further steps to enhance and promote energy-efficient practices in BRI countries. One practical approach is the establishment of energy efficiency standards for the goods and services traded with these countries.

Abstract
To achieve sustainable production and consumption patterns in the modern world, emerging countries are concentrating more on how economic variables may employ carbon neutrality targets appropriately. Using renewable energy, structural changes initiative, and imposing environmental taxes are all part of the plan to achieve the carbon neutrality goal in terms of reduced carbon emissions (CO2), haze pollutants, and greenhouse gases (GHG). Environmental taxation, renewable energy, structural changes, trade openness, and foreign direct investment (FDI) are aspects taken into account in this study, along with the long-term viability of the natural ecology in the E7 (China, Turkey, India, Russia, Brazil, Indonesia, and Mexico) economies. The Driscoll Kraay fixed effect OLS technique and the Method-of-Moment quantile (MMQ) regression technique were adopted for the baseline analysis for the data span of 2000 to 2020. From the empirical analysis, it was discovered that environmental Tax, structure change, and renewable energy have a negative connection with carbon emissions for the understudy countries. Moreover, the pollutant haven hypothesis (PHH) was confirmed since the findings discovered a positively significant relation involving FDI and carbon emission. Similarly, trade openness was seen to have a positive connection with carbon emissions. Thus, it is concluded that effective environmental taxation, renewable energy enhancement, and structure changes mitigate pollution while trade openness and FDI inflow enhance carbon emission for the E7 economies. According to the results, rigorous environmental tax rules will enable enterprises to transition manufacturing to green and sustainable alternatives. Finally, the report recommends that transferring tax money to research and development of sustainable technology programmes will enable governments to meet the SDG-7 and SDG-13 objectives of the United Nations.

Abstract
Despite a spike in publications on business strategies focused on environmental awareness subjects in recent years, business-environment nexus research has recently been criticized for failing to address urgent issues like climate change. Therefore, we endeavored to do a trend analysis to find knowledge gaps in business studies related to the interaction between businesses, the environment, and society using bibliometric. Our study reveals that the area of business sustainability has evolved over the past decade from an internal conquest to include external indices like the environment, such as the debate over the relative merits of social and economic performance and the greening of management. Our findings point to three (3) main conclusions. (1) Many corporations see the urgency of green practices and have distinctive organizational sustainability and business strategies for environmental crises. (2) Business strategy and environment research are concentrated within developed countries to the neglect of developing countries. (3).The literature on business sustainability has not yet given much attention to the managerial implications and effects of climate change. Therefore, scholars must test and develop business-environmental nexuses to aid in sustainable production and consumption improvement.

Abstract
Anthropogenic global warming strategies on carbon mitigation are driven by encouraging green innovation and using carbon taxes, yet an empirical model to validate this is non-existing. Moreover, the existing stochastic effects by regression on population, wealth, and technology (STIRPAT) model has been found to lack policy tools on taxes and institutions that cut carbon emissions. This study amends the STIRPAT model with environmental technology, environmental taxes, and strong institutional frameworks to create a new model STIRPART(stochastic impacts by regression on population, affluence, regulation, and technology) to understand the factors impacting carbon pollution using the emerging 7 economies. Using data from 2000 to 2020, the Driscoll-Kraay fixed effects are employed in this analysis to conduct evidential tests of the impacts of environmental policies, eco-friendly innovations, and strong institutions. The outcomes indicate that environmental technology, environmental taxation, and institution quality decrease E7's carbon emissions by 0.170%, 0.080%, and 0.016%, respectively. It is recommended that E7 policymakers should adopt the STIRPART postulate as the theoretical basis for policies favoring environmental sustainability. The key contribution is the amendment of the STIRPAT model and the enhancement of the market-based mechanisms, such as patents, strong institutions, and carbon taxes, to enable environmental policy to be carried out sustainably and cost-effectively.

Abstract
Mining safety is recognized as one of the factors influencing the mining industry's long-term viability. Therefore, we did a bibliometric analysis to take stock of safety management in the coal mining industry. This study suggests a three-step strategy, comprising literature extraction and screening, bibliometric analysis, and discussion, to provide an in-depth understanding of the present state and development trend of mine safety research. The findings raise additional concerns which include the following: (i) Coal dust pollution has a direct and indirect impact on the environment. (ii) Most research projects have prioritized technology innovation and development over safety norms. (iii) Most works have come from advanced countries such as China, the USA, the UK, and Australia to the neglect of developing nations, leaving a significant vacuum in the literature. (iv) There are more major safety principles in the food business than in the mining industry, indicating a weak safety culture in the mining industry. Additionally, future research goals are provided, such as creating safer policy guidelines to support technological advancements, constructing effective safety mines, and creating solutions to dust pollution and human errors.

Abstract
The main cause of environmental degradation is carbon emissions, which puts environmental sustainability in jeopardy. This ecological worry, the obligation for which falls on all economic actors, has not gone undetected, and so in 2021, the Glasgow Climate Pact (COP: 26) was organized, with the primary aim of decreasing global carbon emissions. Because the Post-Glasgow Agreement goals represent a significant challenge to achieving ecological responsibility, pressure is applied to the participating nations. However, earlier literature lacked sufficient investigation of factors useful for the mitigation of carbon emissions in E7 (China, Turkey, India, Russia, Brazil, Indonesia, and Mexico) economies. Hence, we aim to fill this research vacuum by predicting the impact of clean fuels and cooking technology availability, renewable energy, and environmental taxes on E7 economies' carbon emissions from 2000 to 2020, while taking urbanization and population expansion into account. Evaluation is done using four different cross-sectional dependence (CSD) methods, as well as unit root tests (CIPS and CADF), cointegration analysis (Westerlund and Kao), and the Driscoll-Kraay and quantile-on-quantile long-run factor estimate methods. The long-run analysis revealed from our findings that environmental tax, renewable energy, and access to clean fuels and technologies for cooking decrease carbon emission for the E7 economies. On the other hand, urbanization and population growth enhance emissions for the E7 economies. Finally, our results hold up under a variety of policy interpretations that would aid in reducing carbon emissions and their negative effects on the environment.

Abstract
The implementation of a records management plan is an excellent approach to ensure small and medium-sized enterprises (SMEs) are sustained and continue to expand into huge or multi-national corporations. Maintaining records helps businesses in making better judgments and developing appropriate policies, resulting in enhanced effectiveness and efficiency. This will leverage means for tracking business progress and making appropriate decisions to expand the productive component of the economy. SMEs Business growth will help generate tax revenue for the government while also encouraging poverty reduction through tax transfers. We conducted a thorough investigation to determine the impact of each variable on business growth. For statistical analysis, a partial least squares structural equation modeling (PLS-SEM) methodology was applied. The results suggest that business records management and training have a positive indirect effect on business growth. However, the indirect effect of business records management policies insignificantly influences SMEs’ adoption of adequate record-keeping procedures, which harms business growth in Ghana. On the other hand, the total effect of the variables such as business records management training, business records management policies, and business records management positively impact business growth. Findings make a significant contribution to existing knowledge in the areas of record-keeping, management, and business growth. Business records management is an issue that requires more policy attention. This will business owners and managers strategically plan for new business directions based on data acquired. Proper record-keeping is necessary to satisfy end-users such as company directors, shareholders, external auditors, investors, creditors, and other interested parties. SMEs place a high value on business records management because of the impact it has on their long-term viability. The research outcomes provide a means for, and data on, business appraisal and management strategies.

Abstract
INTRODUCTION Diagnostic Reference Levels (DRLs) are essential for optimisation in mammography. A local DRL for screen-film mammography has been established in Ghana but none exists for the digital mammography systems. Furthermore, technological advancement is phasing out the use of screen-film mammography and replacing it with digital mammography systems. This study aims to establish the local DRLs used in digital mammography across three institutions in Ghana to guide mammography practice. METHODS Average glandular dose (AGD), compressed breast thickness (CBT), age of patients, entrance surface exposure (ESE), kVp, and mAs were retrospectively extracted from three digital mammography systems. The 75th and 95th percentile values were obtained for the AGD of each mammography projection and at CBT of 60 ± 5 mm. The correlation between the AGD and CBT, kVp, mAs, and ESE were investigated. RESULTS The 75th percentile for the AGD at CBT of 60 ± 5 mm for Centres 1, 2, 3, and all centres were 2.3, 1.8, 2.1, and 2.0 mGy respectively. The DRLs obtained were comparably higher than international studies except those of the United Kingdom. The AGD showed a strong positive correlation with the CBT, kVp, mAs, and ESE. There was variability in the AGD applied across the three centres for the craniocaudal (CC) and mediolateral oblique (MLO) projections. The mean AGD, mAs, and ESE for all the three centres and per centre recorded were higher than previous studies, but the mean kVp and CBT were lower than previous studies. CONCLUSION The higher DRLs estimated in this preliminary study indicates that there is a need for dose optimisation in digital mammography practice in Ghana to improve radiation protection. IMPLICATIONS FOR PRACTICE The findings will guide the process of optimisation and limit the variations in the radiation dose during mammography practice.

Abstract
INTRODUCTION Breast compression during mammographic examinations improves image quality and patient management. Several studies have been conducted to assess compression force variability among practitioners in order to establish compression guidelines. However, no such study has been conducted in Ghana. This study aims to investigate the compression force variability in mammography in Ghana. METHODS This retrospective study used data gathered from 1071 screening and diagnostic mammography patients from January, 2018-December, 2019. Data were gathered by seven radiographers at three centers. Compression force, breast thickness and practitioners' years of work experience were recorded. Compression force variability among practitioners and the correlation between compression force and breast thickness were investigated. RESULTS Mean compression force values recorded for craniocaudal (CC) (17.2 daN) and mediolateral oblique (MLO) (18.2 daN), were within the recommended values used by western countries. Most of the mammograms performed - 80% - were within the National Health Service Breast Screening Programme (NHSBSP) range. However, 65% were above the Norwegian Breast Cancer Screening Programme (NBCSP) range. Compression forces varied significantly (p = 0.0001) among practitioners. Compression forces increased significantly (p = 0.0001) with the years of work experience. A weak negative correlation (r = -0.144) and a weak positive correlation (r = 0.142) were established between compression force and breast thickness for CC and MLO projections respectively. CONCLUSION This initial study confirmed that although wide variations in compression force exist among practitioners in Ghana, most practitioners used compression forces broadly within the range set by the NHSBSP. As no national guidelines for compression force currently exist in Ghana, provision of these may help to reduce the range of variations recorded. IMPLICATIONS FOR PRACTICE Confirmation of variations in compression will guide future practice to minimize image quality disparities and improve quality of care.

Abstract
Background and aim There is a growing need to develop new drugs for type II diabetes mellitus (DM) from plant sources due to the high cost and adverse side effects of current drug therapies. To this end, the antidiabetic activity of aqueous stem-bark extract of A. polycarpa (APE) in alloxan-induced diabetic ICR mice was investigated. Experimental procedure The effect of APE (20, 100 and 500 mg/kg), glibenclamide and metformin as positive controls, were determined over 4 weeks on fasting blood glucose (FBG). An oral glucose tolerance test (OGTT) was also conducted. The effects of these treatments on the morphology of the pancreas were assessed. In addition, phytochemical constituents and antioxidant properties of APE were determined. Results and conclusion APE, like glibenclamide and metformin, showed significant hypoglycaemic effect. The OGTT supported the hypoglycaemic effect. The destroyed pancreatic beta-cells in diabetic control mice were restored to normal by APE or drug treatment. APE showed antioxidant activity by scavenging DPPH free radicals; this may be due to the presence of phenolic compounds, particularly flavonoids. Thus, APE may act by restoring pancreatic beta-cell integrity through mopping of reactive oxygen species (ROS) associated with the diabetic state, and thereby improving pancreatic function and consequently, the lowering of FBG levels. These findings provide ample evidence to validate the traditional use of A. polycarpa in the management of DM. Aqueous stem bark extract of A. polycarpa (APE) possesses significant antidiabetic activity. APE has the ability to cause the regeneration of beta cells of the pancreas. APE’s possess antioxidant activity and may scavenge ROS, thus help in overcoming advanced complications of DM. Alkaloids and phenolics (flavonoids) detected may be responsible for the hypoglycaemic and antioxidant activity of APE.

Abstract
Background. The chronological age of the ordinary Ghanaian has often been difficult to verify as registration at birth is not compulsory. Consequently, an accurate method of age determination is needed in competitive age-restricted sports.Objective. To evaluate the age of Ghanaian soccer players who are aspiring to play for the national under-17 (U17) team, using the degree of fusion of the distal radius on magentic resonance imaging (MRI) and comparing it with the Fédération Internationale de Football Association (FIFA) MRI grading.Methods. MRI scans of the left wrists of 86 players aspiring to play for the national U17 football team were recruited for the study during a ‘justify your inclusion tournament’ organised by the Ghana Football Association between June and August 2012. The study was conducted in a diagnostic centre in Accra using a 0.35T MRI scanner. The images were analysed using the previously published FIFA grading system.Results. The mean chronological age of the players was 15.4 years (standard deviation ±0.7; range 12 - 17). The study showed that 43.0% of the MRI images were grade 6 (≥17 years) in relation to the degree of fusion of the distal radius, and 93.0% of the grade 6 players were aged 15 - 16 years chronologically. There was no significant correlation between the chronological age and the degree of fusion (r=0.075; p=0.493).Conclusion. Ghanaian U17 soccer players seem to be more biologically mature than a normative population of the same age category. The lack of correlation between age category and degree of fusion supports the suspicion that most Ghanaian players may not know their true age.

Abstract
This study estimated the patient dose in chest and lumbar spine radiographic examinations in 10 hospitals in Ghana. Dose estimations were done on 1045 patients (aged, 39.6 ± 10.6 y; range 18-85 y) involving 501 (47.9%) males and 544 (52.1%) females for a total of 1495 individual projections. The entrance surface dose (ESD) for the patients was assessed by an indirect method, using the patient's anatomical data and exposure parameters utilised for the specific examination and a Quality Assurance Dose Database software developed by Integrated Radiological Services Ltd in Liverpool, UK. The study showed variations in the ESDs for chest examinations with five of the hospitals having values above the internationally recommended levels. ESDs for lumbar spine anterior-posterior and lateral projections were within acceptable limits. Diagnostic reference levels proposed by the International Commission on Radiological Protection based on patient dose data are imperative to the current Ghanaian situation and will lead to a reduction of the radiation dose.
