Intake of nitrosamine-rich food has been implicated in the pathogenesis of childhood type 1 diabetes mellitus. The present study therefore examines a possible relationship between consumption of charred meat, rich in nitrosamine in pregnancy and the corresponding development of type 1 diabetes in litters. Determination of blood glucose and serum insulin levels in litters showed percent charred ...

The stability of Hg in an acrylonitrile-butadiene-styrene disk certified reference material (ABS disk CRM, NMIJ CRM 8116-a) during measurements by wavelength dispersion X-ray fluorescence (WD-XRF) analysis was evaluated in this study. The XRF intensities of Hg (L(α)) and Pb (L(α)) as well as the XRF intensity ratios of Hg (L(α))/Pb (L(α)) observed under different X-ray tube current conditions a...

The recently acquired archaeological record for soybean from Japan, China and Korea is shedding light on the context in which this important economic plant became associated with people and was domesticated. This paper examines archaeological (charred) soybean seed size variation to determine what insight can be gained from a comprehensive comparison of 949 specimens from 22 sites. Seed length ...

Erbium laser wavelengths circa 3,000 nm are highly energy efficient and spatially accmate for photothermal ablation; their photothermal coagulation depths are significantly shorter than gingival blood vessel diameters. Carbon dimdde (CO~ laser wavelengths circa 10,000 nm are exh·emely effective and spatially accmate photothermal ablation tools with exemplary coagulation ability as a result of a...

The combustion properties of various biomass and wood materials from various references and from our laboratory were reanalysed. The net heat of combustion for cellulosic materials was found to be 13.23 kJ/g times the ratio of stoichiometric oxygen mass to fuel mass, ro, regardless of the material composition. Bomb calorimeter data for original, charred and volatilized material components provi...

Fire safety remains a major challenge for engineered timber buildings. Their combustible nature challenges the design principles of compartmentation and structural integrity beyond burnout, which are inherent to fire resistance framework. Therefore, self-extinction is critical fire-safe This paper first three-part series that seeks establish fundamental underpinning framework timber. The compri...
