    Carbon monoxide (CO) is a highly valuable component of syngas which could be used to synthesize various chemicals and fuels. Conventionally, syngas is derived from fossil-based natural gas and coal which are non-renewable. To curb the problem, CO2 gasification offers a win-win solution in which CO2 is converted with wastes to CO, achieving carbon emission mitigation and addressing waste disposal issue simultaneously. In this review, gasification of various wastes by CO2 with particular focus given to generation of CO-rich syngas is presented and critically discussed. This includes the effects of operating parameters (temperature, pressure and physicochemical properties of feedstocks) and advanced CO2 gasification techniques (catalytic CO2 gasification, CO2 co-gasification and microwave-driven CO2 gasification). Furthermore, associated technological challenges are highlighted and way forward in this field are proposed.

    One of the most crucial attributes of synthetic organic chemistry is to design organic reactions under the facets of green chemistry for the sustainable production of chemicals. Thus, due to the intensified environmental and safety concern, the need for new technologies for conducting chemical transformation has grown. In this regard, there is enormous interest in the use of heterogeneous catalysts as they generally avoid the generation of waste, require fewer toxic reagents, as well as entail easier separation and recycling of the catalyst. α,β-Unsaturated acids have been widely used in various industrial applications and have been identified as one of the most promising chemicals obtained via the Knoevenagel condensation reaction. This review aims to discuss the most pertinent heterogeneous catalytic systems such as zeolites, mesoporous silica, ionic liquids, metal oxides, and graphitic carbon nitride-based catalysts in the Knoevenagel reaction. Ultimately, this review focuses not only on the catalyst but also provides an overall idea and guide for the preparation of new catalysts with outstanding properties by looking at the chemical and engineering aspects such as the reaction conditions and the mechanisms.

    Rapid urbanization and the rising global population have led to the generation of substantial volumes of laundry wastewater. Accordingly, treatment of laundry wastewater has been advocated to curb water pollution and achieve water sustainability. However, technological limitations in treating (specifically) laundry wastewater and the lack of regulations governing the levels of contaminants for such discharges have been perennial problems. This review bridges the knowledge gap by delineating the feasibility of current technologies in laundry wastewater treatment and the experiences of various countries in adopting different approaches. Besides, the feasible methods for collecting laundry wastewater are elaborated. The development of the treatment technologies is highlighted, in which the integrated-treatment processes (physicochemical, biological, and combination of both) are critically discussed based on their functions and methods. A judicious selection of the technologies not only improves the energy efficiency and quality of the treated wastewater, but also mitigates capitals and operational costs. This is projected to enhance public acceptance towards the reuse of laundry wastewater. Thus, the comprehensive assessment herein is envisioned to insightfully guide national policymakers in exploring the viability of the technologies and water-recycling projects. Future research should focus on the techno-economic aspects of the treatment processes, especially their industrial scale-up.

    In this paper, the optimal allocation of constant and switchable capacitors is presented simultaneously in two operation modes, grid-connected and islanded, for a microgrid. Different load levels are considered by employing non-dispatchable distributed generations. The objective function includes minimising the energy losses cost, the cost of peak power losses, and the cost of the capacitor. The optimization problem is solved using the spotted hyena optimizer (SHO) algorithm to determine the optimal size and location of capacitors, considering different loading levels and the two operation modes. In this study, a three-level load and various types of loads, including constant power, constant current, and constant impedance are considered. The proposed method is implemented on a 24-bus radial distribution network. To evaluate the performance of the SHO, the results are compared with GWO and the genetic algorithm (GA). The simulation results demonstrate the superior performance of the SHO in reducing the cost of losses and improving the voltage profile during injection and non-injection of reactive power by distributed generations in two operation modes. The total cost and net saving values for DGs only with the capability of active power injection is achieved 105,780 $ and 100,560.54 $, respectively and for DGs with the capability of active and reactive power injection is obtained 89,568 $ and 76,850.46 $, respectively using the SHO. The proposed method has achieved more annual net savings due to the lower cost of losses than other optimization methods.

    G protein-coupled receptors (GPCRs) belong to the largest family of protein targets comprising over 800 members in which at least 500 members are the therapeutic targets. Among the GPCRs, G protein-coupled estrogen receptor-1 (GPER-1) has shown to have the ability in estrogen signaling. As GPER-1 plays a critical role in several physiological responses, GPER-1 has been considered as a potential therapeutic target to treat estrogen-based cancers and other non-communicable diseases. However, the progress in the understanding of GPER-1 structure and function is relatively slow due to the availability of a only a few selective GPER-1 modulators. As with many GPCRs, the X-ray crystal structure of GPER-1 is yet to be resolved and thus has led the researchers to search for new GPER-1 modulators using homology models of GPER-1. In this review, we aim to summarize various approaches used in the generation of GPER-1 homology model and their applications that have resulted in new GPER-1 ligands.

    While previous research has shown that during mental imagery participants look back to areas visited during encoding it is unclear what happens when information presented during encoding is incongruent. To investigate this research question, we presented 30 participants with incongruent audio-visual associations (e.g. the image of a car paired with the sound of a cat) and later asked them to create a congruent mental representation based on the auditory cue (e.g. to create a mental representation of a cat while hearing the sound of a cat). The results revealed that participants spent more time in the areas where they previously saw the object and that incongruent audio-visual information during encoding did not appear to interfere with the generation and maintenance of mental images. This finding suggests that eye movements can be flexibly employed during mental imagery depending on the demands of the task.

    It is vital for educators to understand and match the learning needs of every student for learning to take place effectively. A detailed reference of the students’ entry characteristics, family background, and previous academic performance is useful in determining the materials and activities to be used with the students. The respondents of this study involved 103 students who enrolled in the pre-higher education programme. The characteristics to identify at-risk students are used as guidelines to redefine the definition of pre-higher education students. Therefore, the study aims to examine the characteristics of pre-higher education students based on their academic performance and socio-economic status. A quantitative method is used to gather more information about the basic entry characteristics, previous academic achievement, family background and Sijil Pelajaran Malaysia (SPM) results of the students. The findings of the study help the researcher to define the terminology of the prehigher education programme. Having to confirm to the conceptual definition of the pre-higher education students helps the policy makers and institutions to develop a suitable learning programme to cater to their learning needs.

    We described a new species of cockroach, Periplaneta gajajimana sp. nov., which was collected in Gajajima, Kagoshima-gun Toshimamura, Kagoshima Prefecture, Japan, on November 2012. The new species is characterized by its reddish brown to blackish brown body, smooth surface pronotum, well developed compound eyes, dark brown head apex, dark reddish brown front face and small white ocelli connected to the antennal sockets. In male, the tegmen tip reach the abdomen end or are slightly shorter, while in the female, it does not reach the abdominal end and exposes the abdomen beyond the 7th abdominal plate. We confirmed the validity of this new species by breeding the specimens in our laboratory to demonstrate that the features of the progeny were maintained for several generations. For comparison and easy identification of this new species, the key to species identification of the genus Periplaneta that had been reported in Japan to date are also presented.

    A cross sectional study was conducted in Kelantan state with the objectives to determine the prevalence of smoking in 2004 and to determine the relationship between smoking and age, sex, educational level, family and peer influence. All residents aged 15 years and above from all the selected households were included in this study. A standardized pre-tested structured questionnaire was used in this study. Out of 1025 respondents interviewed the prevalence of ever and current smokers was 34% and 25.1% respectively.The prevalence of ever smokers and current smokers was significantly higher In males as compared to females (p.<0.001). The mean initiation age for the males current smokers was 10.4 (95% CI = 19.4, 21.5) years with a range from 7 to 66 years. For the females the mean initiation age was 31 (95% Cl =26.8, 35.2) years with a range from 15 to 64 years. The difference between the mean initiation age between male and female smokers was statistically significant (p<0.0001). The overall mean duration of smoking was 23.9 years with a median of 23 years. It ranged from less than 1 year to 66 years. There was no significant difference between the mean duration of smoking between male and females current smokers (p =0.59). There was a significant association between current smoking status and education level (p<0.01 ) and between smoking and peer influence (p<0.01). There was no significant difference in smokers whose parents were smokers as compared to non-smokers whose parents were smokers. In conclusion the prevalence of smoking in Kelantan state in 2004 is lower than the reported prevalence in 1996. However, it is still very high especially in the males.

    A cross sectional survey was conducted in Kampung Datuk Kerarnat, an urbanized residential area in Kuala Lumpur from August to November ZOO5 to assess knowledge, attitude and preventive practices on dengue among its residents. A two stage sampling strategy was used to select survey household. An adult aged at least 21 years old was identified from each selected household and interviewed using a standardized questionnaire. Data was collected on demographics, dengue related KAP and house-types. Knowledge, attitude and practice were assessed using a scoring system. Each appropriate answer was given a point and the points for each section of the questionnaire were totalled. Knowledge was assessed as ‘good' or ‘moderate to poor’ based on arbitrary cut-off point. Out of 133 respondents interviewed, 78.2% were able to identify at least one clinical sign of dengue, 73% knew that dengue fever was caused by the bite of dengue infected Aedes mosquitoes, 71 % correctly identified breeding sites, 69.2% correctly identified the Aedes mosquito and 42% correctly reported biting times ofthe mosquito vector. Overall, knowledge
    was categorized as poor, attitude was good and dengue control and prevention practices was moderately poor. There was a weak but significant positive correlation between knowledge and practice (r=0.271, p=0.002) but there was no significant correlation between attitude with practice and between attitude with knowledge (p>0.05) . The results suggested that inspite of good attitude l
    on dengue fever, it did not correlate with good practices and good knowledge in dengue prevention. We conclude that there is a need to increase health promotion activities to increase knowledge which forms the basis for preventive practices as part of the strategy to control dengue. Preventive strategies are the only means of controlling the disease.

    Smaller family size and advancing parental age have increased the demand for prenatal diagnosis.
    Prenatal cytogenetic diagnoses currently used, such as amniocentesis and chorionic villus
    sampling, are usually not preferred by the expectant couples due to the risk imposed on the mother and child. High false positive rates (5%) of current non-invasive screening methods, such as serum analysts or ultrasound, cause a large number of unnecessary invasive practices to be performed, which apart from the associated risk, place considerable psychological distress on the couples
    involved (Wald et al., 1999). (Copied from article).

    A community-based study of childhood injuries in Kedah was undertaken in January-March 1996. The aims were to determine the types and frequencies of injuries reported; to assess the association between injury and selected variables (age, sex, place, number of children in the family, presence of care-givers and treatment); and to recommend further research and policy for childhood injury prevention. A total of 448 injuries were recorded from 1089 children in 451 randomly selected households. The incidence was 411.4/1000. There appeared to be a decrease in risk of injury as the number of children per household increased. The effect of lower age on injury was significant (p>0.05). Male children were 1.5 times more likely to injure themselves than female children when data were controlled for number of children in the household. Falls accounted for 53.3% of all injuries sustained, and occurred more frequently when the child was with non-family members. Different injury categories were associated with different caregiver categories. It is concluded that child injury prevention programmes require more data on injury situations and collaborative efforts between clinical, health and and behavioural professionals.

    Indonesian government secures the access of the poor towards health services through subsidised schemes. This study is aimed to describe the pattern of health expenditure by households and to describe the pattern of health service utilisation across household’s socioeconomic level in the city of Padang after seven years of the introduction of subsidised schemes. A household survey was conducted involving 918 households, with multistage random sampling method. The proportion of out-of-pocket (OOP) health spending as a share of household’s capacity to pay was regressive across consumption quintiles. The proportion of households with catastrophic health expenditure was 1.6% while 1.1% faced impoverished health expenses. Among those who need health care, the utilisation among the rich was higher than the poor. Health insurance schemes in Padang provides financial protection, however with regards to household’s capacity to pay, the poor has the higher burden of health payment. The gap on health service utilisation between the poor and the better-offs was still apparent for outpatient services and it has been narrowed for inpatient care. This study suggests that the subsidised schemes for the poor are highly needed and the possibility of the leakage of subsidies to the rich should be considered by the government.

    Over the last decade, Egypt's aquaculture sector has expanded rapidly, which has contributed substantially to per capita fish supply, and the growth of domestic fish markets and employment across the aquaculture value chain. Despite the growing importance of aquaculture sector in Egyptian labour force, only a few studies have explored the livelihoods of Egypt's women and men fish retailers. Even fewer studies have examined gender-based market constraints experienced by these informal fish retailers. This study uses sex-disaggregated data collected in 2013 in three governorates of Lower Egypt to examine the economic and social constraints to scale of enterprises between women (n = 162) and men informal fish retailers (n = 183). Specifically, we employ linear regression method to determine the correlates of enterprise performance. We found that both women and men retailers in the informal fish market earn low profits and face livelihood insecurities. However, women's enterprise performance is significantly lower than that of men even after controlling for individual socio-economic and retailing characteristics. Specifically, the burden of unpaid household work and lack of support therein impedes women's ability to generate higher revenues. These findings strengthen the argument for investing in understanding how gender norms and attitudes affect livelihood options and outcomes. This leads to recommendations on gender-responsive interventions that engage with both men and women and enhance the bargaining power and collective voice of fish retailers.

    Discharge of household greywater into water bodies can lead to an increase in contamination levels in terms of the reduction in dissolved oxygen resources and rapid bacterial growth. Therefore, the quality of greywater has to be improved before the disposal process. The present review aimed to present a hybrid treatment system for the greywater generated from households. The hybrid system comprised a primary stage (a natural filtration unit) with a bioreactor system as the secondary treatment combined with microalgae for greywater treatment, as well as the natural flocculation process. The review discussed the efficiency of each stage in the removal of elements and nutrients. The hybrid system reviewed here represented an effective solution for the remediation of household greywater.

    Although evidence of mosquito coils' impact on disease epidemiology is limited, they are popularized as mosquito-borne disease prevention devices. Their usage affects the environment, human and mosquito health. This study investigated the perception, usage pattern and efficacy of coils in a predominantly poor malaria-endemic Ghanaian peri-urban area. Information on protection methods, perception and usage pattern was garnered using questionnaires. The efficacy of commonly used coils in the area was then assessed on the malaria vector, Anopheles gambiae, in a glass chamber. Sole or co-application of mosquito control methods and risky usage practices were reported. Coils were deemed harmful to humans and mosquitoes, and their perceived effectiveness varied, with several factors influencing their purchase. High d-allethrin concentration coils induced quicker mosquito knockdown; however, mortality was less than 85%. The coil usage pattern compromises users' health and can enhance mosquito tolerance to d-allethrin. The coils were ineffective against the vector, outlining a dichotomy between the users' perception of efficacy and the observed efficacy. Hence, the usage of other safer and more effective vector control methods should be encouraged to protect households.

    INTRODUCTION: Despite the health risks associated with secondhand smoke (SHS) exposure, smoking in the home is common in Malaysia, and almost exclusively a male behavior.

    AIMS AND METHODS: This study explored male smokers' knowledge, beliefs, and behaviors related to SHS exposure and smoking in the home, to guide future intervention development. Twenty-four men who smoked and lived in Klang Valley, Kuantan, or Kuala Terengganu took part in semi-structured interviews which explored knowledge and beliefs regarding SHS in the home, and associated home-smoking behaviors. Data were managed and analyzed using the framework approach.

    RESULTS: There was limited knowledge regarding the health risks associated with SHS: the smell of SHS in the home was a more prominent concern in most cases. Many had no rules in place restricting home smoking, and some suggested that smoking in specific rooms and/or near windows meant SHS was not "shared" with other household members. A few fathers had created but not maintained a smoke-free home prior to and/or after their children were born. Desire to smoke in the home conflicted with men's sense of responsibility as the head of the household to protect others and set a good example for their children.

    CONCLUSIONS: Men's home-smoking behaviors are shaped by a lack of understanding of the health risks associated with SHS exposure. Gaining a broader understanding of the factors that shape men's decisions to create a smoke-free home is important to facilitate the development of culturally appropriate interventions that address their responsibility to protect other household members from SHS exposure.

    IMPLICATIONS: Our findings highlight the need for public information campaigns in Malaysia to educate men who smoke regarding the health harms associated with SHS in the home and the ways in which SHS travels and lingers in household air. This is important given men's concerns about SHS often focus on the smell of cigarette smoke in the home. Our findings suggest a number of potential avenues for future intervention development, including household and community-level initiatives that could build on men's sense of responsibility as the head of the household and/or their general desire to protect their families.

    This study examined the effect of various dimensions of women's empowerment on childcare use in Nigeria, utilizing information from five rounds of the National Demographic and Health Surveys. The analysis made use of both binary and multinomial logistic regression. The findings show that women who share household choices with their spouses were more likely to undertake postnatal care for their babies in either private or public hospitals compared to self-medication/others/traditional. Also, women who owned houses and those who participate in economic activities are significantly more inclined to use postnatal services for babies in health facilities. By implication, women empowerment is a significant factor to consider in improving childcare services in Nigeria. This suggests that in order to improve the health of children, women's inputs in household decision-making should be accommodated, while efforts should be made to enhance household socioeconomic position, and support mothers to have formal education. The findings also suggest that promoting women's empowerment can play a crucial role in increasing the demand for formal childcare services.

    The popularization of financial literacy has become a global trend, with governments across the world expressing commitment to continuously enhancing the financial literacy of their citizens to improve the country's overall financial well-being. However, there is a lack of research evaluating the actual effects of financial literacy on Chinese households. This study first investigated the micro impact of financial literacy on the household stock profit level using data from the 2019 China Household Finance Survey. As most existing studies use factor analysis to measure financial literacy from a single dimension of financial knowledge, our study additionally used the entropy method to construct a composite evaluation system of financial literacy from four dimensions: financial skills, knowledge, attitudes, and behaviors. The ordinary least squares model was utilized as the primary regression model to estimate the correlation, and the average financial literacy of other households in the same community was selected as an instrumental variable. Further instrumental variable regression analysis was conducted using the two-stage least squares method. Three robustness tests were performed to ensure the reliability of the research findings. The results demonstrate that financial literacy significantly enhances household stock profit levels. The mediation effect analysis indicates that financial literacy affects stock profit levels through financial information attention. Moreover, financial literacy has a more substantial promoting effect on stock profit levels for households with members working for state-owned enterprises and those living in first-tier cities. This study confirms the value of financial literacy; identifies important channels for residents to increase their property income; and provides important guidance for the government, educational organizations, and financial institutions. This also injects more vigor into market participation to improve the persistently sluggish Chinese stock market.
