JOURNAL FREE ACCESSWe examined the effect of the butter and margarine contents in dough on the lipid composition of deep-fried doughnuts. An increasing content of butter or margarine in the dough increased the absorption of frying oil and the efflux of butter or margarine from the dough during the deep-frying procedure, and also increased the efflux of cholesterol from the dough. Differing butter or margarine content in the dough did not result in a differing fatty acid composition in the resulting doughnuts due to the higher efflux of fatty acids from the dough.View full abstractDownload PDF (2788K) -

JOURNAL FREE ACCESSTo study thermal sensitivity of hands against different water temperatures, thermal sensitivity was investigated in relation to physiological responses such as finger skin temperature and finger skin blood flow, when dipping both hands wearing gloves or bare hands in water bath set in the temperature range 15-40°C. Nine healthy female students were selected as subjects. The interval of uncertainty (IU) against water temperatures was defined as thermal sensitivity. The finger skin temperature, finger skin blood flow and blood pressures were measured together with the thermal sensitivity. Thermal sensitivity of hands was hardly affected by change in water temperature and wearing gloves. The finger skin temperature and the finger blood flow increased significantly with increasing water temperature and were less sensitive when gloves were worn. The decreases in blood pressures observed by the wearing of gloves were confirmed when the hands were dipped in cold water. It was determined that the physiological responses are sensitive to wearing of gloves and water temperature, while thermal sensitivity is independent of both of them.View full abstractDownload PDF (1594K) -

JOURNAL FREE ACCESSHeat transfer coefficients for heat transfer across an air layer (boundary film) around glass bottles (250 ml-20 l) have been measured as a model for determining heat transfer coefficients around the human body. Overall heat transfer coefficients obtained from an unsteady-state method coincided with those from a steady-state method. The heat transfer coefficient of air boundary film is determined from the overall heat transfer coefficient by taking into account the heat transfer across the insulated part and that within the bottle. The heat transfer coefficient is the sum of the radiation and convection transfer coefficients. The radiation transfer coefficient can be determined theoretically. The heat transfer coefficient obtained for natural convection differed little from the coefficients of simple-shaped bodies such as a vertical wall, a horizontal pipe and so on. The coefficients correlated with the diameter of the bottles and temperature differences within boundary film. The heat transfer coefficient obtained for forced convection also coincided with those of a pipe and a sphere without any significant differences. The coefficients correlated with the diameter of the bottles and wind speed.View full abstractDownload PDF (692K)

--Evaluation by Using Sensory Evaluation Clothing Pressure and EMG--Chika SHIMOSAKA, Izumi NAKADA, Michiko ISHIGAKI, Mieko INOMATA2008 Volume 59 Issue 1 Pages 29-35

JOURNAL FREE ACCESSIn this investigation, sensory evaluation, clothing pressure, and EMG were used to determine the influence that different sleeve widths have on arm movement. Subjects were 5 healthy university students aged 21 to 24 years. Three different sleeve widths were compared (A: upper arm circumference+11 cm, B: upper arm circumference+7 cm, C: upper arm circumference+3 cm). Five types of upper limb movements were measured. The result of ANOVA for sensory evaluation of sleeve widths was significant at the 0.1% level, with narrower sleeve widths ranking lower. The result of ANOVA for maximum clothing pressure for the upper arm circumference of sleeves was significant at the 0.1% level, with narrower sleeve widths showing higher clothing pressure. The result of ANOVA for EMG of sleeve widths was significant at the 5% level. For abduction movement, the deltoid muscles activity increased in proportion to a decrease in sleeve width. A high correlation was obtained between the sensory evaluation and maximum clothing pressure. It was shown that maximum clothing pressure on the upper arm circumference affected the sensibility of motion adaptability.View full abstractDownload PDF (2592K) -
