Thermal insulated PVC windows for residential buildings: feasibility of insulation performance improvement by various elemental technologies

Herein, we aimed to improve the thermal insulation of polyvinyl chloride (PVC) windows to reduce the energy consumption of buildings. Currently, the gold standard PVC window is triple glazed and has a thermal transmittance of 0.7 W/(m2·K). However, further reduction in the thermal transmittance of the windows via quadruple glazing is not feasible because this would make the windows too heavy and expensive. We searched for an alternative method for reducing the thermal transmittance without increasing the weight. The window frame, glazing, and glazing edge parts of a PVC window significantly affect the overall thermal insulation; thus, we evaluated the insulation contribution of each of the above to identify their optimal conditions. Using these optimal conditions, we were able to create a window having a thermal transmittance of 0.46 W/(m2·K). However, these optimal conditions make their production difficult. Hence, we manufactured an alternative using practical specifications more suited for actual production. This window achieved a thermal transmittance of 0.63 W/(m2·K)

Measures against COVID‐19 concerning Summer Indoor Environment in Japan

Information on air‐conditioning and ventilation has been continuously disseminated in response to the Japanese Government's announcement of the need for appropriate ventilation measures against the new coronavirus disease (COVID‐19), and the issuing of an emergency presidential discourse by the presidents of Engineering Societies. In this paper, we add to the information the latest knowledge on the behavior of SARS-CoV-2 in air, describe its diffusion characteristics in the built environment, and summarize the effects of temperature and humidity on the virus. Then we recommend varying approaches of air‐conditioning control for facility type

Raw diffraction images of 5-Chlorotryptamine-bound trypsin

Trypsin is an enzyme in the first section of the small intestine that starts the digestion of protein molecules by cutting these long chains of amino acids into smaller pieces. We used datasets to investigate the protocol of detecting polymorphs using Hierarchical clustering (Acta D., submitted). All diffraction data were collected at BL32XU, SPring-8, using an automated data collection system ZOO. Data were acquired from four crystals of 5-Chlorotryptamine-bound trypsin. All datasets were collected using a continuous helical scan scheme for 360º oscillation with the following experimental parameters; Beam size: 10 µm × 15 µm, Wavelength: 1.0000 Å, Total dose/crystal: 10 MGy, Detector: EIGER X 9M (DECTRIS Co. Ltd.). All crystals belonged to space group P212121 with unit cell parameters roughly corresponding to a=54.5, b=58.6, c=66.6 Å

Raw diffraction images of [NiFe]-hydrogenase maturation factor HypD from Aquifex aeolicus (C360S mutant)

HypD is one of the maturation factors of [NiFe]-hydrogenase and can form a complex with other maturation factors (Muraki et al., 2019). We used datasets to investigate the protocol of detecting polymorphs using Hierarchical clustering (Acta D., submitted). All diffraction datasets were collected at BL45XU, SPring-8, using an automated data collection system ZOO. From six crystals, datasets were collected from each one using a continuous helical scan scheme for 360º oscillation with the following experimental parameters; Beam size: 20 µm × 20 µm, Wavelength: 1.0000 Å, Total dose/crystal: 10 MGy, Detector: EIGER X 9M (DECTRIS Co. Ltd.). All crystals belonged to space group P212121 with unit cell parameters roughly corresponding to a=60.0, b=62.6, c=97.6 Å
