- Multidrug resistant (MDR) Salmonella are a leading cause of foodborne diseases and serious human health concerns worldwide. In this study we detected MDR Salmonella in broiler chicken along with the resistance genes and class 1 integron gene intl1. A total of 100 samples were collected from broiler farms comprising 50 cloacal swabs, 35 litter and 15 feed samples. Overall prevalence of Salmonella was 35% with the highest detected in cloacal swabs. Among the Salmonella, 30 isolates were confirmed as S. enterica serovar Typhimurium using molecular methods of PCR. Disk diffusion susceptibility test revealed that all the Salmonella were classified as MDR with the highest resistance to tetracycline (97.14%), chloramphenicol (94.28%), ampicillin (82.85%) and streptomycin (77.14%). The most prevalent resistance genotypes were tetA (97.14%), floR (94.28%), blaTEM-1 (82.85%) and aadA1 (77.14%). In addition, among the MDR Salmonella, 20% were positive for class 1 integron gene (intl1). As far as we know, this is the first study describing the molecular basis of antibiotic resistance in MDR Salmonella from broiler farms in Bangladesh. In addition to tetA, floR, blaTEM-1, aadA1 and intl1 were also detected in the isolated MDR Salmonella. The detection of MDR Salmonella in broiler chicken carrying intl1 is of serious public health concern because of their zoonotic nature and possibilities to enter into the food chain.

- This paper aims to establish consumers perception of electric waste recycling and management on a national scale in Bangladesh. The attitude, willingness to pay (WTP) and consumers behaviour were explored by conducting a questionnaire-based survey. The conclusions are based on 915 valid responses out of 2000 online survey invitations. Interestingly, 37.9% of the respondents indicated that they would accept to pay for electronic waste recycling. Analysis also shows that the preferred WTP would cover 5-10% of the recycling cost. Factors like environmental awareness, monthly income, and education level affect the consumers WTP. Nevertheless, most of the participants believe that the Government should share the recycling cost. The study suggests that e-waste recycling can be stimulated by promoting environmental awareness, educating the public about the benefits of recycling e-waste, and making e-waste recycling more convenient. However, additional measures will likely be needed to tackle the e-waste problem. Thus, support for environmental education is imperative in order to promote environmental awareness and increase the WTP of consumers. The study outlines key characteristics of consumer-focused e-waste management archetypes and proposes an effective road map for Bangladesh.

- Excessive food waste (nearly 1.3 billion tons per annum) has exacerbated the world hunger crisis. This comprehensive review focuses on the food waste scenario, adverse effects, food waste management, existing waste management policies, and regulations in Bangladesh. Municipalities and urban centers generate 3.78 million tons of waste each year (15.96% of total food waste). This study utilized the national database to analyze food waste generation and projected growth by the year 2050. Yearly an estimated 17215.2 thousand acres of land and a significant amount of natural resources (water, energy) are being used to produce 23691.15 thousand tons of wasted food (45% of total food production). This study critically analyzed the waste management policy gap of Bangladesh and clearly identified each stage of the food loss production supply chain. The study assessed that yearly 481.6 MW energy could be generated from food waste. Focusing on effective policy and sustainability, a national food waste management model has been proposed for Bangladesh in compliance with sustainable development goals 12.3.1 global food loss. Food accumulates 16.7% to 20% of the world economy; therefore, any measures taken to reduce the food waste will be economically beneficial and environmentally sustainable.

Feasibility study and optimization of solar-assisted intermittent microwave-convective drying condition for potato

- Intermittent microwave-convective drying (IMCD) is an advanced drying technology that overcomes the shortcomings of microwave, convective, and microwave-convective drying. Research on the feasibility study of solar-assisted IMCD along with investigating its microstructure change, nutritional analysis, and appearance of dried food materials is inadequate. This research aims to investigate the effects of microwave intermittency-on quality attributes and structural changes of potato slices. In addition, optimization of pulse ratio has been performed in this study. Drying experiments, namely convective drying (CD) and IMCD, were conducted to assess the quality of dried potato slices. It was found that IMCD took only 12 min to complete the drying process, whereas CD took approximately 300 min. The optical (colour) and nutritional (vitamin C) properties of the IMCD dried potato slices appeared better than those of hot air-dried samples. The overall techno-economic analysis indicates that the proposed solar-assisted IMCD can dry an equal amount of potato while consuming one-tenth of the required energy of CD. Therefore, successful industrial application of the proposed drying system might be a stepping stone in the way to the advancement of energy-efficient food drying systems.

Nanogenerators-Based Self-Powered Sensors

Forskningsöversikt (refereegranskat)abstract
- With the rapid technological development, self-powered sensor systems that are capable of operating without an external power supply are becoming more and more crucial in the field of sensing and detection. One of the major drawbacks of a typical sensor is the necessity of an external power supply or batteries, which makes sensor systems more complex and less handy for mobile devices. In the last decade's improvement of triboelectric, piezoelectric, pyroelectric, and thermoelectric nanogenerators and their performance in electrical output and mechanical stability, it becomes widely used in the field of self-power sensing systems for healthcare, mechanical and environmental applications. Here in this review, the various types of nanogenerators working principles is first discussed, the output performance is analyzed, and then their recent progress in the application of self-powered sensor systems, including biomedical and healthcare, wearable devices, physical applications, robotics, environmental monitoring, and smart cities, is highlighted. Except for the practical application of self-powered sensors, a future outlook of the self-powered sensor systems is prognosticated.

- Extreme weather events in South and Southeast Asia exert profound psychosocial impacts, amplifying the prevalence of mental illness. Despite their substantial consequences, there is a dearth of research and representation in the current literature. We conducted a systematic review of observational studies published between January 1, 2000, and January 20, 2024, to examine the impact of extreme weather events on the mental health of the South and Southeast Asian population. Quality assessment of the included studies was conducted using the Newcastle-Ottawa Scale (NOS) quality appraisal checklist. The search retrieved 70 studies that met the inclusion criteria and were included in our review. Most were from India (n = 22), and most used a cross-sectional study design (n = 55). Poor mental health outcomes were associated with six types of extreme weather events: floods, storm surges, typhoons, cyclones, extreme heat, and riverbank erosion. Most studies (n = 41) reported short-term outcome measurements. Findings included outcomes with predictable symptomatology, including post-traumatic stress disorder, depression, anxiety, general psychological distress, emotional distress and suicide. Limited studies on long-term effects showed higher mental disorders after floods and typhoons, while cyclone-exposed individuals had more short-term distress. Notably, the review identified over 50 risk factors influencing mental health outcomes, categorized into six classes: demographic, economic, health, disaster exposure, psychological, and community factors. However, the quantitative evidence linking extreme weather events to mental health was limited due to a lack of longitudinal data, lack of control groups, and the absence of objective exposure measurements. The review found some compelling evidence linking extreme weather events to adverse mental health in the South and Southeast Asia region. Future research should focus on longitudinal study design to identify the specific stressors and climatic factors influencing the relationship between climate extremes and mental health in this region.
