Ulceration of the skin due to contact with hexavalent chromium was first described by Cummings in 1827. One hundred years later, in 1928, Blair published a study of 12 cases of skin and nasal ulceration at a time when chrome plating had become commercially successful. Formal regulations to protect workers heath were introduced for the first time in the UK in 1931, when the risks of occupational...

The price of Internet services is user information, and many pay it without hesitation. While myriad privacy tools exist that thwart the detailed compilation of information about user habits, these tools often assume that reduced functionality is always justified by increased privacy. In contrast, we propose the adoption of functional privacy as a guiding principle in the development of new pri...

PURPOSE The purpose of this study was to investigate the marginal precision of computer numeric control-milled frameworks fabricated of grade 4 commercially pure titanium or cobalt-chrome alloy through digital technology and to compare them with conventional cast frameworks. MATERIAL AND METHODS A titanium cast of a mandibular arch with six implant analogs was used as a master. The master cas...

Abstract An observational study was conducted to investigate the effect of Phi-Chrome (chromium propionate) on feedlot cattle performance in commercial conditions Mexico. Performance data from 116 closeouts pens involving 7,207 crossbred bulls (25% Bos taurus - 75% indicus) fed 140 d with or without were collected a located central Mexico and analyzed; DMI, ADG, FE 58 over 2019 (control, 0 ppb ...

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 ...

background: biomonitoring provides a useful tool to estimate the genetic risk from exposure to genotoxic agents. the aim of this study was to assess the potential cytogenetic damage associated with occupational exposure to hexavalent chromium by using micronuclei (mn) as a biomarker. methods: this was a cross-sectional study and all participants were males. both the exposed and control individu...

Google Chrome has implemented a number of “HTML5” APIs, including the Geolocation API and various storage APIs. In this paper we discuss some of our experiences on the Google Chrome team in implementing these APIs, as well as our thoughts around privacy for new APIs we are considering implementing. Specifically, we discuss our ideas of how providing access to things such as speech, web cameras,...
