It has been proposed that 90% of American's diets are deficient in the trace essential mineral chromium. Several chromium(III) dietary supplements are currently available to alleviate this deficiency. We show here that the same pharmacokinetic models that have been used to quantitate absorption of chromium(III) in humans predict that ingested chromium(III) will accumulate and be retained in hum...

Toxic heavy metal pollution of water and soil is a major environmental concern for which conventional remediation approaches do not provide an appropriate solution. Phytoremediation, which involves removal of pollutants from water and soil through plants, is of low cost and environmentally friendly. In this study, the phytoremediation potential of Lemna minor for the uptake of Cr(VI) at the opt...

The overall aim of the research was to better understand the influence of raw material characteristics on the quality of decorative veneer, to identify phenotypes of oak and sessile oak valuable for veneer use, and to promote quality in relationship with sustainable development of Romania’s forests. This paper describes specific aspects regarding wood defects and quality conditions imposed on r...

We present a novel method to design shells with artistic cutouts in a manner that produces a stable final result. The process of stenciling, removing material with a fixed shape, is a particularly appealing way to introduce a decorative pattern into the design of architectural structures, furniture, or household objects. However, removing material can easily weaken an object to the point where ...

Animal studies conducted in the 1950's, first suggested that chromium played a role in glucose metabolism. Experiments that restricted chromium intake in monkeys and rats were able to induce a state of glucose intolerance. This condition, similar to diabetes, was readily reversible with chromium supplementation. Clinical relevance were reported in the late 1970's when several cases of patients ...

I t has been reportedthat trivalent chromium plays an important role in insulin action. We have shown that, in the presence of trivalent chromium, insulin stimulated the glucose utilization of isolated rat lenses. This finding suggested the possibility that a variation in dietary chromium might be responsible for the repeated inconsistency in the insulin effect observed on the glucose utilizati...

Recent studies have shown that the positive emotional design of learning environments might foster learning performance. In contrast, the seductive detail effect postulates that additional, learning irrelevant details inhibit learning. This research focusses on the implementation of decorative pictures as a prime for emotions and context-relatedness. This study examines four groups of decorativ...

The decorative panels in the foyer of the Teatro Amazonas, inaugurated in 1896, stand out from the rest of the building's ornamental iconography. The rubber trade brought great wealth to the capitals of Pará and Amazonas and as these cities gained national and international fame, their urban fabric and forms of sociability underwent significant changes. The article looks for parallels between t...
