Pressure comfort sensation and discrimination on female body below waistline

The garment pressure comfort sensation and discrimination were studied in the paper. The garment pressure comfort threshold and difference threshold were defined and calculated according to staircase method of psychophysics. In experiment, 10 subjects were employed in sensory tests and pressure measurements. A novel stretchable compressive belt was developed, which was used to control the pressure applied on separate body parts by its extension and intention, and the subjects judgement and pressure monitor were recorded in times. Finally, the comfort thresholds at nine separate body parts below waistline and difference thresholds at three parts & three varied standard pressure levels were investigated. This study provided proper comfort pressure range to human body for developing compression wear.

Practitioner summary: Garment pressure comfort and difference threshold were firstly defined and calculated according to staircase method of psychophysics. The comfort thresholds at nine body parts and difference thresholds at three parts & three varied standard pressure levels were investigated. This study provided proper comfort pressure range to human body for developing compression wear.     

温石棉细小纤维性能及其对石棉胶乳抄取板质量的影响

以五级温石棉为研究对象,通过筛分的方法,把石棉纤维分成长纤维和细小纤维两部分,对长纤维单独磨浆,然后与筛分收集到的细小纤维以不同比例混合后配抄,探讨长纤维磨浆转数、细小纤维含量对石棉胶乳抄取板性能的影响。结果表明,与直接对石棉原料进行磨浆相比,单独对筛分得到的长纤维磨浆然后与细小纤维混合后配抄,可使抄取板的抗张指数提高64.5%。长纤维最佳的磨浆转数为1500转,当细小纤维含量为30%时,抄取板的抗张指数最大,为11.3N.m/g。     

Effects of UV-C and single- and multiple-cycle high hydrostatic pressure treatments on flavor evolution of cow milk: Gas chromatography-mass spectrometry,electronic nose,and electronic tongue analyses

The effects of Ultraviolet Light-C and single- and multiple-cycle high hydrostatic pressure treatments on the flavor evolution of cow milk were studied using solid-phase microextraction-gas chromatography-mass spectrometry, electronic nose, and electronic tongue analyses. The milk samples showed significant differences in their electronic nose profiles, but almost similar in the electronic tongue profiles. The variety and content of volatile compounds in the milk were increased after high hydrostatic pressure and Ultraviolet Light-C treatments, in which Ultraviolet Light-C treatment increased the variety and content of volatiles more than 6–8 times and 27.4–54.4%, respectively, than that of the high hydrostatic pressure treatment. Two 2.5-min cycles of high hydrostatic pressure treatment at 200 MPa resulted in the minimum amount of aliphatic hydrocarbons (25.4%) and maximum amount of aromatic hydrocarbons (31.1%); one 5-min cycle at 400 MPa and two 2.5-min cycles at 600 MPa produced the maximum amount of aliphatic hydrocarbons (45.6%) and acids (27.3%), respectively. The Ultraviolet Light-C treatment produced the maximum amount of aldehydes, aliphatic hydrocarbons, and alcohols.
