CO2 emissions, energy consumption and economic growth: Evidence from the Trans-Pacific Partnership

The paper investigates the role of consumption of both renewable and sustainable energy, as well as alternative and nuclear energy, in mitigating the effects of carbon dioxide (CO2) emissions, based on the Environmental Kuznets Curve (EKC). The papers introduces a novel variable to capture trade openness, which appears to be a crucial factor in inter-regional co-operation and development, in order to evaluate its effect on the environment, The empirical analysis is based on a sample of nine signatories to the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) for the period 1971-2014, which is based on data availability. The empirical analysis is based on several time series econometric methods, such as the cointegration test, two long run estimators, namely the fully modified ordinary least squares (FMOLS) and dynamic ordinary least squares (DOLS) methods, as well as the Granger causality test. There are several noteworthy empirical findings: it is possible to confirm the U-shaped EKC hypothesis for six countries, namely Australia, Canada, Chile, New Zealand, Peru and Vietnam; there is no evidence of the EKC for Mexico; a reverse-shaped EKC is observed for Japan and Malaysia, there are long run relationships among the variables, the adoption of either renewable energy, or alternative energy and nuclear energy, mitigates CO2 emissions, trade openness leads to more beneficial than harmful impacts in the long run, the Granger causality tests show more bi-directional-relationships between the variables in the long run, and the Granger causality tests show more uni-directional-relationships between the variables in the short run

Application of the cut-off projection to solve a backward heat conduction problem in a two-slab composite system

The main goal of this paper is applying the cut-off projection for solving one-dimensional backward heat conduction problem in a two-slab system with a perfect contact. In a constructive manner, we commence by demonstrating the Fourier-based solution that contains the drastic growth due to the high-frequency nature of the Fourier series. Such instability leads to the need of studying the projection method where the cut-off approach is derived consistently. In the theoretical framework, the first two objectives are to construct the regularized problem and prove its stability for each noise level. Our second interest is estimating the error in -norm. Another supplementary objective is computing the eigen-elements. All in all, this paper can be considered as a preliminary attempt to solve the heating/cooling of a two-slab composite system backward in time. Several numerical tests are provided to corroborate the qualitative analysis.Peer reviewe

Radicular cyst in a primary molar following pulp therapy with gutta percha : a case report and literature review

A radicular cyst (RC) in deciduous dentition is relatively rare. This clinical report presents a case of RC that condition derived from a primary molar undergone an endodontic treatment with gutta-percha approximately one year ago. In addition, we also considered whether intracanal medicaments and gutta-percha filling material related to the formation and development of the cyst or not

Effectiveness of perindopril/amlodipine fixed-dose combination in the treatment of hypertension: a systematic review

Background: Uncontrolled blood pressure is a major risk factor for cardiovascular diseases. Fixed-dose combination (FDC) therapy offers a promising approach to addressing this challenge by providing a convenient single-tablet solution that enhances the effectiveness of blood pressure control. In our systematic review, we assess the effectiveness of perindopril/amlodipine FDC in managing blood pressure.Methods: We conducted a comprehensive search across four primary electronic databases, namely, PubMed, Virtual Health Library (VHL), Global Health Library (GHL), and Google Scholar, as of 8 February 2022. Additionally, we performed a manual search to find relevant articles. The quality of the selected articles was evaluated using the Study Quality Assessment Tools (SQAT) checklist from the National Institute of Health and the ROB2 tool from Cochrane.Results: Our systematic review included 17 eligible articles. The findings show that the use of perindopril/amlodipine FDC significantly lowers blood pressure and enhances the quality of blood pressure control. Compared to the comparison group, the perindopril/amlodipine combination tablet resulted in a higher rate of blood pressure response and normalization. Importantly, perindopril/amlodipine FDC contributes to improved patient adherence with minimal side effects. However, studies conducted to date have not provided assessments of the cost-effectiveness of perindopril/amlodipine FDC.Conclusion: In summary, our analysis confirms the effectiveness of perindopril/amlodipine FDC in lowering blood pressure, with combination therapy outperforming monotherapy and placebo. Although mild adverse reactions were observed in a small subset of participants, cost-effectiveness assessments for this treatment remain lacking in the literature

Spatiotemporal evolution of SARS-CoV-2 Alpha and Delta variants during large nationwide outbreak of COVID-19, Vietnam, 2021

We analyzed 1,303 SARS-CoV-2 whole-genome sequences from Vietnam, and found the Alpha and Delta variants were responsible for a large nationwide outbreak of COVID-19 in 2021. The Delta variant was confined to the AY.57 lineage and caused >1.7 million infections and >32,000 deaths. Viral transmission was strongly affected by nonpharmaceutical interventions

The economic circumstances of widows in Vietnam.

Information on the living conditions of widows in Vietnam is limited. Prior studies of gender gaps have identified widows as vulnerable to the risks of poverty. However, widows are only included as a sub-group in broader studies of women's well-being. Large gaps remain in the knowledge based on the factors affecting both widows' susceptibility to poverty and the conditions or circumstances that might minimize these risks. This paper attempts to help redress these knowledge gaps by contributing an analysis of data from the 2018 Vietnam Household Living Standard Surveys. The paper compares the likelihood of poverty for widowed and other households using probit regression. It also assesses whether widows who head up their households face different risks of poverty from those who live in other households. Finally, the paper examines the effects on the risk of poverty of a range of social, demographic and locational characteristics of widow households in Vietnam. Our results indicate that widowed households have experienced a higher probability of falling into poverty. Moreover, widow-headed households have faced more vulnerability to fresh water and housing, especially among widowed households. Policy implications have emerged based on the findings of this paper

Does gender and education of the households’ heads matter for wealth accumulation in Vietnam? Evidence from a recent decade

Asians believe that education plays a crucial role in earning higher income for individuals and accumulating larger wealth for households. Educational achievements have been generally considered an indicator of success. However, gender bias in favour of males as the household heads still exists in Asian societies due to the significant influence of Confucian belief. This study investigates the independent effect of education and gender of the households' heads and their joint effect on household wealth in the Vietnamese context in the most recent decade using data from the Vietnam Household Living Standards Surveys (VHLSSs) between 2010 and 2020. Our study uses quantile regression and propensity score matching methods to ensure the robustness of the empirical results. We find that the education of the household heads contributed to increased household wealth in Vietnam in 2010 and 2020. However, household wealth decreases across different wealth quantiles when the households' heads are females. These findings confirm the currently deep-rooted gender stereotypes and a ‘gendered structure’ economy in Vietnam and require attention from the Vietnamese government. In addition, our empirical results reveal that being a female as the household head with a degree/certificate from a general education will increase household wealth. Our empirical results have largely been consistent across different wealth distributions

Understanding the characteristics of the household energy transition in a developing country

Understanding the energy transition process in developing countries is crucial to implement policies to reduce the use of traditional fossil fuel-based energy sources, which increase pollution, worsen global climate change, and negatively impact people's health. Existing literature indicates that households account for approximately 25% of total energy consumption for consumption and production activities. However, understanding the energy consumption patterns of choices of energy sources and their determinants has largely been neglected in the existing literature. As such, this study uses the multivariate probit model to identify the factors influencing household energy choices in Vietnam, using data from 2016 to 2020 from the Vietnamese Households Living Standard Surveys (VHLSS). Our study focuses on how households' multiple occupations, particularly in rural areas, affect energy sources choices. We find that households participate in different agricultural sub-sectors simultaneously, resulting in differential access to multiple energy sources. Households engaging in cultivation, forestry, and animal husbandry activities are more likely to choose coal, fuelwood, and biomass as the primary energy sources for production and daily uses. In contrast, higher household income and household head with higher education level also increases the likelihood of choosing cleaner energy choices for daily uses and production activities. In addition, our empirical findings confirm the validity of the ''energy stacking” hypothesis rather than the “energy ladders'' hypothesis – two contrasting hypotheses concerning household energy transition in the literature. Policy implications have emerged based on the findings of this paper to enhance the clean energy transition in Vietnam in achieving sustainable economic development and social transformation and her commitment to combating global climate change issues
