Experimental and numerical studies are carried out in this study to characterize the flexural properties of ultra-high-performance fiber-reinforced concrete (UHPFRC) beams with and without an initial notch reinforced with micro here steel fibers in overall ratios of 2% by volume.Dimensions of the notch were 5 mm in width, and 25 mm in height.For th
The development in digital screen technology has exponentially increased in the last decades, and many of today’s electronic devices use light-emitting diode (LED) technology producing very strong blue light (BL) waves.Long-term exposure at LED-BL seems to have an implication in the dehydration of the epidermis, in the alterations of shape an
Background: This paper investigated the effect of daylight on morning and night melatonin, subjective general health using GHQ questionnaire, sleepiness and alertness on elderly who lived in nursing houses.Methods: Nineteen nursing home residents participated voluntarily.They exposed to daylight from 9 to 10 a.m.and from 4 to 5 p.m.for 6 wk.The lev
Rut formation caused by logging operations has been recognised as click here a challenge for Swedish forestry.Frequent traffic with heavy machines on extraction roads, together with a warmer climate, is one of the factors that increases the risk of rut formation in forests.One possible way to control this impact of logging operations is to design a
Abstract Objective Training models are required to impart surgical skills, like wound closure techniques, arrethe bush balm prior to practice in patients.In an ideal case, the tissue characteristics of the model are close to those of humans, easy to create and of low cost.Methods Here, we describe a model to train students in wound closure techniqu
