A high risk for the development of diffuse pleural mesothelioma is known to exist in various occupational settings associated with the use of asbestos.' Although a serious hazard has been recognised among asbestos miners, millers, and shipyard workers, recent evidence suggests that a high risk of mesothelioma may exist among occupational groups previously thought to be at low risk for developin...

expert system to aid the M1 Abrams tank mechanic find-and-fix problems in the AGT-1500 turbine engine. TED was designed to provide the apprentice mechanic with the ability to diagnose and repair the turbine engine like an expert mechanic. The expert system was designed and built by the U.S. Army Research Laboratory and the U.S. Army Ordnance Center and School. This article discusses the relevan...

Crystalline molecular machines represent an exciting new branch of crystal engineering and materials science with important implications to nanotechnology. Crystalline molecular machines are crystals built with molecules that are structurally programmed to respond collectively to mechanic, electric, magnetic, or photonic stimuli to fulfill specific functions. One of the main challenges in their...

One of the most challenging tasks while designing an automotive electronic device is to take into account its whole electro-mechanic environment, so that time expensive failure tests can be reduced. We show a case study, developed in collaboration with an industrial partner, in which an automotive Compact Disk (CD) player is modelled. Using VHDL-AMS, not only its whole mixed-signal electro-mech...

Mechanic antennas provide opportunities for human portable, VLF communications, where a rotational dipole emits EM signals with angular momenta. In this paper we analytically derive the electromagnetic fields from electric using Fourier transform method, and find that radiated carries nonzero energy flow density in both orbital spin momentum (AM) parts by AM flux tensors. Intuitively, rotation ...

This study was done as a part of a larger research project where the interest was on exploring if and how gameplay design could give informative principles to the design of educational activities. The researchers conducted a series of studies trying to map game mechanics that had the special quality of being inclusive, i.e., playable by a diverse group of players. This specific study focused on...

Industrial wastes may produce leachates that can contaminate the aquatic ecosystem. Toxicity testing in acute and chronic levels is essential to assess environmental risks from the soluble fractions of these wastes, since only chemical analysis may not be adequate to classify the hazard of an industrial waste. In this study, ten samples of solid wastes from textile, metal-mechanic, and pulp and...
