A desire to increase automation or to eliminate the use of mercury has prompted several ASTM committees to consider alternatives to ASTM Liquid-in-Glass (LiG) thermometers. In this paper, we address the technical issues of choosing an alternative. We first discuss the basic properties and relative merits of platinum resistance thermometers, thermistors, and thermocouples in the context of repla...

In this research (using induction furnace process) nodular iron with three different percentages of copper (residual, 0.5% and 1,2%) was obtained. Chemical analysis was performed by mass spectrometry and microstructures were characterized by Optical Microscopy (ASTM E3) and Scanning Electron Microscopy (SEM). The study of mechanical behavior was carried out in a mechanical test machine (ASTM E8...

List of Tables Table 1 Advantages and disadvantages of sediment toxicity tests (modified from ASTM 2003a). Table 2 Rating of selection criteria for estuarine or marine amphipod sediment toxicity testing (ASTM 2003a). Table 3 Comparison of habitat characteristics and other life history parameters of four estuarine or marine amphipod species used in sediment toxicity tests (ASTM Table 4 Recommend...

A rapid simulated distillation method is described for analysis of petroleum fractions boiling within the range of ASTM D2887 [1]. The method employs an Agilent 6890N gas chromatograph (GC) equipped with a split/splitless inlet, flame ionization detector (FID), oven insert, and 3-meter 180-μm id capillary column. A SIMDIS software package is partially integrated into the GC ChemStation for data...

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 ...
