Abstract:
... Mosquito-borne disease research in India has remained stagnant for decades, and will continue to remain. This is so as the hard work in the field by entomologists has given way to comfortable work in air-conditioned laboratories, with computer as the main tool. Critical reviews are being written by men not of science, and also others, but our government totally ignores them. ...

Abstract:
... Controlling the work mode of building energy equipment by the artificial neural network (ANN) is an advanced technology for improving the indoor thermal environment. However, few investigations were conducted on the application of ANN in controlling BIPV/T systems. In this work, a regulation method based on ANN was developed to control the operation strategy of a hybrid BIPV/T façade. To evaluate ...

Abstract:
... Exhaust and non-exhaust particulate matter (PM) is regarded as the most significant airborne during driving. Among the source of non-exhaust PM, the tire-wear particles (TWP) can be quantified using pyrolysis-gas chromatography/mass spectrometry (Py-GC–MS). TWPs are fragmented by continuous weathering once exposed to the road. Approximately 5 wt% of carbon black (CB) bound in the rubber matrix of ...

Abstract:
... Going by current usage trends, the use of room air conditioners will increase by three times by 2050. Therefore, it is necessary to investigate an ultra-efficient air conditioner with extremely low operating energy consumption to realize the goal of climate change, especially in the (sub) tropical area. In this paper, an ultra-efficient air conditioner with smart evaporative cooling ventilation an ...

... Waste printed circuit boards (WPCBs) contain valuable material resources and hazardous substances, thereby posing a challenge for sustainable resource recovery and environmental protection initiatives. Overcoming this challenge will require mapping the toxic footprint of WPCBs to specific materials and substances used in manufacturing electronic components (ECs). Therefore, this work collected 50 ...

Abstract:
... As global temperatures go up and incomes rise, air conditioner sales are poised to increase dramatically. Recent studies explore the potential economic and environmental impacts of this growth, but relatively little attention has been paid to the implications for inequality. In this paper we use household-level microdata from 16 countries to characterize empirically the relationship between climat ...

Abstract:
... Daily commutes can contribute disproportionately to overall daily exposure to urban air pollutant concentrations. It is important to understand factors that contribute to the variability of exposures during commutes to develop strategies to mitigate exposure. We used low-cost Fairsense PMS1003 sensors to monitor exposure to multiple air pollutants: PM₂.₅, PM₁₀, SO₂, CO, O₃ and NO₂, across four dom ...

Abstract:
... Dragon fruit (Selenicereus spp.) is a high‐value crop in the Philippines. It is commonly propagated using stem cuttings, which quality is essential for fruit production. Several pathogens have been reported to cause various diseases in dragon fruit worldwide. These diseases affect stem and fruit quality in the field, but the consequences during storage are unknown. This study aims to determine the ...

Abstract:
... Demand-side flexibility (DSF) has been touted as a possible solution to the challenges in power system operation arising from increasing intermittent renewables penetration and the emergence of electric vehicles. In Singapore, where around 24 to 60% of electricity demand in buildings could be attributed to heating, ventilation, and air conditioning (HVAC) purposes, air-conditioned buildings repres ...
