We developed and evaluated a device that can be used for the quantitative measurement of stickiness. While a typical pressure distribution sensor can measure a pressing force, it cannot measure a tensile force. We therefore installed a pin array on a sensor, with the pin array applying an offset pressure to the sensor through its weight. We measured the stickiness of natto and baby powder using...

• The ejection of blood into the root of the aorta by the heart produces pressure changes which are transmitted peripherally through the vascular bed. The propagation of these pressure waves has been a topic of interest and conjecture for a number of years because of its importance in the study of the physical properties and energetics of the vascular bed. As a result many data have accumulated...

The ratioβ of the radiation pressure force to the gravitational attraction is calculated for circumstellar grains. Eleven stars of various spectral type are considered and their spectral flux compiled from available data sometimes supplemented by appropriate models. The materials composing the grains are a silicate (obsidian), organic materials (ice tholin, poly-HCN), graphite and glassy carbon...

Fibromyalgia is a disease in which postural control and balance is impaired and tendency to falls increases. The aim of this study is to detect the presence of plantar loading impairment and to evaluate the relationship between potential plantar pressure changes and clinical signs in fibromyalgia syndrome patients. Thirty-eight female fibromyalgia patients and age and gender-matched 33 healthy ...

INTRODUCTION Doing repetitive push-ups is among the most common exercise for the upper body and shoulder stabiliser muscle strength training. However, adverse effects such as neck pain, back pain, palmar pain and wrist pain have been reported. To date, to our knowledge, palmar pressure when performing push-ups has not been previously reported. We hypothesised that various hand positions during ...

In recent years, pressure-driven analyses of water distribution systems using pressure-flow relationships (PFRs) were shown to be more computationally efficient than those based on flow-pressure (FPRs), such as the widely used Wagner equation and various spline approximations. Using a PFR enhances convergence properties Newton–Raphson method by most network (WDN) solvers. This paper derives new...

High sleep quality promotes efficient performance in the following day. Sleep quality is influenced by environmental factors, such as temperature, light, sound and smell. Here, we investigated whether differences in the interface pressure distribution on healthy individuals during sleep influenced sleep quality. We defined four types of pressure models by differences in the area distribution an...

The present study aims at investigating stress and deformation behavior of rotating thick truncated conical shells subjected to variable internal pressure. Material prpperties of the shells are graded along the axial direction by Mori-tanaka scheme, which is achieved by elemental gradation of the properties.Governing equations are derived using principle of stsionary total potential (PSTP) and ...
