Protecting children from injuries caused by fall accidents from playground equipment is important. Therefore, measures toward minimizing the risk of fall accident injuries are required. The risk of injury can be evaluated using ASTM F1292. In this test, G-max and the HIC are used to estimate the risk of injury. However, the measurement procedure is too complicated for application to a large num...

Late-life depression affects 2-6% of seniors aged 60 years and above. Patients are increasingly embracing non-pharmacological therapies, many of which have not been scientifically evaluated. This study aimed to evaluate a category of meditation, automatic self-transcending meditation (ASTM), in alleviating symptoms of depression when augmenting treatment as usual (NCT02149810). The preliminary ...

This paper investigates the effectiveness of two zeolites with different reactive silica content, fly ash (FA), blast furnace slag (BFC), silica fume (SF), and micronized calcite (MC) in reducing expansion of concrete due to alkali-silica reaction. Also in this research, effects of three different cement usages were investigated by using accelerated mortar bar method, ASTM C1260. Five different...

Magnesium is the lightest of all the commonly used metals. It is one of the most abundant elements in the earth's surface, amounting to a mass fraction of c.a. 2.5 %. It has been prepared for industry as metal and alloy ingots; the latter are most often made with aluminum. Various magnesium-based alloys have been developed and mainly applied to transport facilities and mobile electric devices b...

Since 1980, ASTM has required that test methods include statements on the precision and bias of each method. E384 and B578, each committee responsible for these documents, E04 and B08, initiated new interlaboratory comparison studies, commonly referred to as round-robins. These studies involve circulating standard materials to each of several chosen laboratories for measurements. Considerable a...
