Studies on double selenates. Part 12. Thermal decomposition of ammonium selenate and of double selenates of lanthanide, and yttrium, and ammonium

Thermogravimetry (TG) up to 900°C, differential thermal analysis (DTA) up to 1100°C and gravimetric data up to 1200°C, have been used to study the thermal decomposition of ammonium selenate and of the double selenates of lanthanides, and yttrium, and ammonium. The results provided the composition and thermal stability and also an interpretation of the thermal decomposition mechanisms. © 1994.

Protese ocular individualizada em resina acrílica com esfera oca

The technique proposed aims at reducing the weight of individualized ample ocular prostheses using acrylic resins as well as simplifying laboratory procedure. For that, prefabricated hollow spheres made of plastic material, were inserted in the sclera. The average weights of the solid conventional sclera (5.30g) and those of the respective prefabricated plastic ones (3.91g) were compared. The weight reduction was significative with a confidence interval of 95% by the Student t test. ln addition, for illustration purpose, the technique was applied to patients in the ward of the Maxillofacial Prostheses Dicipline of the Dentistry School in the Campus of São José dos Campos - UNESP, having each patient received a solid prosthesis and a hollow prefabricated one made of plastic material. It has been concluded that the prostheses material spheres were inserted are lighter than the ones which received solid spheres; furthermore, thr technique is viable for ample anophtalmic cavities and requires few sessions

Estudo do efeito de cério como sensibilizador e ativador, em matrizes de difenilfosfinatos de lantânio, dopadas com európio e/ou térbio

This paper aims the preparation, characterization and study of luminescence, particularly as for the cerium ion action as activator or sensitizer, in diphenylphosphinate of lanthanum compounds trivalent ions cerium-, europium-, and/or terbium-doped. The following compounds were prepared and studied: i) La1-(x+y)CexEuy(DFF)3; ii) La1-(x+y)CexTby(DFF)3; iii) La1-(x+y+z)CexEuyTbz(DFF)3, with x = 10%, y = 5% e z = 5%. The diphenylphosphinate of lanthanum, Ln[(Ph2)PO2]3, are complexes obtained by the mixture of lanthanides chlorides with diphenylphosphinic acid, ethanol medium. These compounds make white powders, crystalline, insoluble in normal temperature and pressure, and are chemically and thermally stable. When doping with Ce3+, Eu3+ and/or Tb3+, the compounds present characteristic luminescence. Luminescent materials are made of a host matrix incorporated with few amounts of ions called activators, which are able to present luminescence after being excited by UV light or high energy radiation, and sensitizer ions, which have the role of absorbing excitation energy and transfer it to the activator, for it to emit luminescence radiation. The infrared vibrational spectroscopy indicates that the coordination occurs by the oxygens of phosphorile group with ΔνPO of about 40 cm-1 compared to the free ligand. The X Ray difractograms of compounds Eu- and/or Tb-doped are similar, but they present profile of diffraction different observed by Stucchi and col. In previous papers, indicated an influence of Ce in the crystalline phase formation of these matrices. In luminescence spectrums, the excitation that can be made by the levels of ligand in 273 nm, or cerium ion in area between 300 and 400 nm were observed. In the emission spectrum, with excitation in 273 nm, is possible to observe the emission of Ce3+ below 400 nm and the Eu3+ in 592, 611 and 617 nm, and the...as a sensitizer to.

Chicken meat consumer profile in northwestern São Paulo State, Brazil

Brazil is the world’s first chicken meat exporter nowadays. The maintenance of this position requires a constant quality attributes evolution. This work evaluated the chicken meat consumer profile in the northwest region of São Paulo state, the most important Brazilian poultry meat consumer market, in order to provide information to the productive sector. The data were collected using 482 interviews and questionnaires that were answered by e-mail. The questionnaires involved questions related to the consumer identification, habits and preferences and their knowledge about food safety, production system, sustainability and animal welfare. Most of the consumers, 62%, were female, with ages ranging from 20 to 50 years. Beef was preferred by the majority of the answerers and chicken and pork meat were together the second choice. Only 2% of the interviewed consumers mentioned not enjoying poultry meat. The main part of consumers, 67%, prefer to buy breast and leg cuts and only 11% are used to buy the whole poultry carcass. More than 60% of the interviewed have already eaten free range chicken meat, but the majority of them, 89%, are used to consume regular industrialized poultry. About 75% of the consumers believe hormones are used to grow the birds. Over 80% of people observe the expiration date before buying the product, but only 55% check if it has the stamp of the official inspection service. Color and appearance of meat are the most important factors that influence the consumer’s choice. The amount of water that drips on the tray is a rejection factor to 88% of answerers. Most of them, 66%, prefer lighter colored meat. Only 27% of them believe that chicken meat causes an environmental impact and 48% do not know the meaning of animal welfare. More than half of the interviewed do not consider animal welfare aspects before consuming any kind of meat. From these results obtained, it is possible to conclude that any effort to improve the product quality, mainly concerned to animal welfare and sustainability aspects, requires prior educational initiatives.

Diferentes fontes de carboidratos em rações para leitões desmamados com diferentes pesos: pH e microbiota do trato gastrintestinal

Forty eight piglets from a commercial strain weaned at an average age of 21 days were used in order to evaluate effects of carbohydrates sources (lactose or maltodextrin) and the weights of piglets at weaning on the stomach pH, colon and rectum contents, and the amount of total coliform, Escherichia coli and Lactobacillus spp in digesta of ileum and cecum. The experiment was conducted in a randomized block design and analyzed in split plot, considering class of weight and carbohydrates as main plots and the slaughter age of animal as sub-plots. The stomach pH and intestinal contents were not influenced by the diets provided as well as the amount of total coliform. It was found that the presence of lactose in the feed decreased counts of Escherichia coli and Lactobacillus ssp in the ileum. Regarding the class of weight, the lighter piglets had lower counts of Escherichia coli and Lactobacillus. The maltodextrin can be used as an alternative to replace the lactose in the diet, regardless of the piglets weight at weaning, as it does not adversely affect the pH and the Lactobacillus population in the gastrointestinal tract.
