Far-infrared rays have certain kinds of effects on the human body, especially on skin, blood circulation, and skin cell vitalizing. Some jewelry powders radiate far-infrared rays. Jade has powerful far-infrared ray radiation, and tourmaline has pyroelectric and piezoelectric properties and radiated far-infrared rays. The jewelry powders (fine powdered jade and tourmaline powders) were screened ...

This case illustrates the importance of a thorough clinical history and the benefit of histopathologic examination. The history of contact allergy to jewelry provided an early clue, and the microscopic features confirmed the clinical impression of allergic stomatitis.

o We further analyse a sub-set of commodity-related goods jewellery, fuel and metals. These goods offer a clean quasi-experimental setting to look at the effects of a pure change in price on criminal activity. Specifically, they are homogenous in their quality and supported by efficient resale markets (for example, the scrap metal recycling industry). Price changes for these goods are also exog...

Biological treatments to degrade cyanide are a powerful technology for cyanide removal from industrial wastewaters. It has been previously demonstrated that the alkaliphilic bacterium Pseudomonas pseudoalcaligenes CECT5344 is able to use free cyanide and several metal-cyanide complexes as the sole nitrogen source. In this work, the strain CECT5344 has been used for detoxification of the differe...

Traditionally, toolmark test exemplars are produced by applying a tool's working surface to a piece of soft metal such as lead. Soft, pliable metals are primarily used for this purpose because they will replicate the microscopic grooves present on a tool's working surface without damaging the tool. In this paper the authors present an alternative material for the preparation of test toolmarks. ...
