THE most important and most costly industrial disease is contact dermatitis and the most common cause of that is chromate sensitivity. This collection of monographs, edited by Dr Desmond Burrows is timely and fills an important gap in our literature. Chrome is very widely used in industry and its use is increasing yearly, no less than 124 different jobs in industry where workers are exposed to ...

A t-chrome cover is a cover of a weighted graph by vertex sets that induce t-colourable subgraphs. We investigate the problem of determining the minimal number of sets needed for such a cover, and give conditions under which this number is directly derived from the clique number and the maximum weight of the graph. The problem of minimal t-chrome covers is relevant to frequency assignment in ce...

Web-based applications typically collect enormous archives of usage data — including profiles of users, their usage environment, locality, and their browsing behaviour — that are often disregarded or unused by the development team. This paper explores whether such usage data can be unified with development information, such as the release history, to assess the sustainability of a software proj...

The surface and optical properties of black chrome films prepared by two different electrochemical baths were characterized. The black chrome films have been deposited on bright nickel substrates by electroplating technique. The surface morphology and phase structure of the films were investigated by using scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively. The chemica...

A new passive sampler based on low-density polyethylene (LDPE) layflat tube filled with chrome shavings from tannery waste residues was evaluated to determine volatile organic compounds (VOCs) in indoor and outdoor areas. VOCs were directly determined by head space-gas chromatography-mass spectrometry (HS-GC-MS) without any pretreatment of the sampler and avoiding the use of solvents. Limit of ...

PEEK-OPTIMA™ (Invibio Ltd, UK) has been considered as an alternative joint arthroplasty bearing material due to its favourable mechanical properties and the biocompatibility of its wear debris. In this study, the potential to use injection moulded PEEK-OPTIMA™ as an alternative to cobalt chrome in the femoral component of a total knee replacement was investigated in terms of its wear performanc...

Ge, B, P-doped silica glass films are widely used as optical waveguides because of their low losses and inherent compatibility with silica optical fibers. These films were etched by ICP !inductively coupled plasma" with chrome etch masks, which were patterned by reactive ion etching !RIE" using chlorine-based gases. In some cases, the etched surfaces of silica glass were very rough !root-mean s...

Abstract A new method is presented using electrochemically generated ferrate to degrade the technically relevant bio‐based side‐stream products, lignin and lignosulfonate. An exclusive degradation vanillic acid found, which was previously a reported by‐product. As natural resource, can be utilized substitute fossil‐based chemicals in industry reduce greenhouse gas emissions positively impact cl...
