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...

Applications for lignin and lignosulfonates are limited today due to the undefined structure and varying properties of the substance. However, lignin, as the second most abundant bio-resource besides cellulose and the bio-resource with one of the highest natural carbon contents, has the potential to act as a precursor for carbon materials. In this study we have applied a Kraft lignin and a sodi...

This study compares the effectiveness of multi-micronutrient formulations containing iron (Fe), manganese (Mn), and zinc (Zn) with traditional (EDTA, DTPA, HEEDTA, and EDDHAm) or novel chelates (o,p-EDDHA, S,S-EDDS, and IDHA) and natural complexing agents (gluconate and lignosulfonate). The stability and reactivity of the formulations were studied on batch experiments with calcareous soil and b...

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 ...
