Espectroscopia infravermelha para a determinação de carbono do solo: perspectiva de um método economicamente viável e ambientalmente seguro.

O objetivo deste trabalho foi apresentar a utilidade das técnicas DRIFTS e NIRS na determinação quantitativa de carbono total (CT) determinado por combustão via seca e carbono orgânico (CORG) determinado por oxidação com dicromato de potássio, usando uma série heterogênea e representativa de solos do Brasil. Calibrações foram feitas para o número total das amostras e para as sub-populações de amostras com base no teor de C, classe de solo e grupo textural.bitstream/CNPAF/25440/1/comt_126.pd

Potentially irritant preservatives in newborn baby cosmetics – analysis of labels of products sold in Portugal

The use of cosmetics containing preservatives might pose a risk to the skin health of newborns, despite improving their adaptation to the external environment. The present work aimed at depicting the potentially hazardous preservatives in cosmetics sold in the district of Porto, Portugal. A total of 281 labels from newborn cosmetics were analyzed. From 729 different ingredients found in the analyzed labels, 15 were preservatives with previously recorded irritant activity, being sodium benzoate the most mentioned (n = 118). There was a significant difference between the means of number of preservatives with an irritant potential present in the products sold in pharmacies and in the products sold in supermarkets. Most analyzed products contained at least one preservative. Still, the choice of cosmetics for newborns should consider those with a minimum number of preservatives, being more probable to choose a less sensitizing product in pharmacies than in supermarkets.info:eu-repo/semantics/publishedVersio

Relationship between feed efficiency indexes and performance, body measurements, digestibility, energy partitioning, and nitrogen partitioning in pre-weaning dairy heifers.

Abstract The objectives of this study were: 1) to classify animals into groups of high and low feed efficiency using two feed efficiency indexes (Residual feed intake (RFI) and residual feed intake and body weight gain (RIG)), and 2) to evaluate if pre-weaning heifer calves divergent for feed efficiency indexes exhibit differences in performance, body measurements, digestibility, energy partitioning, and nitrogen partitioning. A total of 32 Gyr heifer calves were enrolled in a 63-d trial and classified into two feed efficiency (FE) groups based on RFI and RIG (mean ± 0.5 SD). The groups were classified as high efficiency (HE) RFI (HE RFI, n = 9; HE RIG, n = 10), and low efficiency (LE) RFI (LE RFI, n = 10; LE RIG, n = 11). The remaining animals were classified as intermediate (n = 13 (RFI) and n = 11 (RIG)). HE and LE calves had RFI values of?0.052 and 0.049 kg/d (P < 0.05), respectively. The HE RFI group consumed 8.9% less solid diet than the LE RFI group. HE RFI animals exhibited an increased digestibility of crude protein and ether extract and tended to have greater total dry and organic matter digestibility. LE RFI animals had greater gross energy and nitrogen intake, though greater fecal losses resulted in a tendency to reduce energy and nitrogen use efficiency. HE and LE calves had RIG values of 0.080 and -0.077kg/d (P ? 0.01), respectively. HE RIG animals exhibited greater average daily gain (9.4%), body weight (BW), and heart girth, though HE RIG group exhibited narrower hip width. HE RIG animals tended to have greater ether extract digestibility but greater methane losses (% of gross energy). HE RFI in pre-weaning heifers seems to be related to differences in digestibility. Divergent animals for RIG during the assessed phase appear to differ in body measurements, which may be related to differences in the composition of the gain
