Summary: This paper investigates the effects of different multi-impeller air supply modes on the indoor airflow and temperature distribution. Compared with other air supply modes, the six-impeller air conditioner (SIAC) has a relatively far air supply distance and significantly improves the indoor environment. The SIAC also reduces airflow friction and loss, allowing for better cold and heat exchange in the indoor space. Analysis of the indoor thermal environment using various methods shows that the six-impeller mode provides better thermal comfort.

Summary: There is a global movement towards creating green buildings driven primarily by energy or carbon concerns, but there is a growing recognition that greener buildings could affect Indoor Environment Quality (IEQ). However, localized green building codes in developing countries often do not systematically recognize IEQ or health as crucial issues, which remain understudied. It is crucial for green buildings to perform holistically in order to be effective, especially as the developing world is expected to nearly double current global built floor space by 2050.

Summary: As people spend more time indoors, the indoor environment and air quality become crucial for their health and well-being. Incorporating natural elements in indoor spaces can not only improve the environment and air quality but also provide multiple benefits to physical and mental health due to the biophilic effect. The study evaluated the performance of a living green curtain prototype as a shading device, comparing it with no curtains and external blinds. Results showed that the green curtain provided cooler temperatures, with a difference of up to 8 degrees C on hotter days, and recorded the highest daily average relative humidity of 67% due to the evapotranspiration effect. This study highlights the potential of green curtains in improving air quality and thermal comfort.

Summary: This research examines the impact of Buddhism on mergers & acquisitions (M&As) performance using data from 4622 M&A transactions of Chinese public firms between 2004 and 2018. The findings provide ample evidence that acquirers located in regions with a higher intensity of Buddhism achieve better short-term and long-term performance after the merger. Furthermore, the study reveals that state ownership plays a crucial role in mitigating this effect, and the value creation is driven by higher deal completion rates and fewer violation cases for acquiring firms. Finally, the study addresses the issue of endogeneity, and the results remain unchanged.

Summary: Monitoring the potential formaldehyde emission of wood-based materials through test chamber investigations has significantly contributed to reducing indoor formaldehyde concentrations. However, the different methodologies used in these procedures prevent direct result comparison. Empirical models for converting formaldehyde steady-state concentrations based on temperature, humidity, air change rate, and loading were developed in the 1970s and have been modified to accommodate the development of lower-emitting materials. Formaldehyde emissions from wood-based materials are complex and require nonlinear regression tools for mathematical analysis.

It was found that reducing short-wavelength light during the day did not change the concentration of u-sMEL. Personal photopic illuminance was positively correlated with u-sMEL in the reference week. The illuminance had a significant impact on u-sMEL, as shown by the evaluation of the mean of all three urine samples. However, this correlation was not found in the experimental week.
