The object of this study was to compare the mass concentration of airborne dust during circular sawing of five wood-based materials: solid sugi (Cryptomeria japonica) lumber, tropical hardwood plywood, softwood plywood, particleboard, and medium-density fiberboard. Specimens were sawn at a constant feed per tooth (0.05 mm) using two saw speeds. The mass(More)
To understand the changes in radiocesium (137Cs) concentrations in stem woods after the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident, we investigated 137Cs concentrations in the bark, sapwood, heartwood, and whole wood of four major tree species at multiple sites with different levels of radiocesium deposition from the FDNPP accident since 2011(More)
A DNA fragment carrying the gene encoding poly(3-hydroxybutyrate) (P(3HB)) depolymerase was cloned from the genomic DNA of Marinobacter sp. DNA sequencing analysis revealed that the Marinobacter sp. P(3HB) depolymerase gene is composed of 1734bp and encodes 578 amino acids with a molecular mass of 61,757Da. A sequence homology search showed that the deduced(More)
An Occupant Classification System (OCS) that detects the existence and physique of the passenger seat occupant for the Advanced Air Bag requirements of FMVSS208 was developed. This paper describes an OCS which distinguishes small women (5th percentile adult female dummy: AF05) from young children (less than 6-yearold child dummy: AC06) pertaining to the(More)
To elucidate the temporal changes in the radiocesium distribution in forests contaminated by the Fukushima Daiichi Nuclear Power Plant accident, we monitored the 137Cs concentration and inventory within forests from 2011 to 2015 across nine plots containing variable tree species and different contamination levels. The 137Cs concentrations in needles and(More)
BACKGROUND Early-onset hyperkalemia often occurs in extremely preterm infants during a few days after birth. While there are several treatments for hyperkalemia, calcium infusion to reduce plasma potassium concentrations remains controversial. The purpose of this study is to investigate whether a high dosage of calcium reduces early-onset hyperkalemia. (More)
