title: USE OF COMMERCIAL STEEL WOOL PADS FOR THE TREATMENT OF WASTEWATER CONTAINING HEXAVALENT CHROMIUM FROM ELECTROCOLORATION PROCESSES OF STAINLESS STEELS

description: Residual solutions containing Cr(VI) ions can be harmful to the environment as well as to human health. Hence, practical and efficient methods for the treatment of such solutions are welcome. In this note, the treatment with commercial steel wool pads of a Cr(VI) residual solution from electrochemical coloration processes of stainless steel is described in detail. Successful treatment was achieved when an amount of steel wool equivalent to 20% in excess in relation to the theoretical stoichiometric amount was used, followed by chemical precipitation with sodium hydroxide up to pH 10-11 and separation by filtration under reduced pressure. The treatment yielded a final solution with concentrations of Cr(III) and Cr(VI) ions of only 0.29 ± 0.02 mg L-1 and &lt; 0.01 mg L-1, respectively. These concentration values are significantly lower than the maximum limits established by CONAMA for industrial wastewaters, attesting the efficiency of the treatment.

title: Metalloproteinases in hoof laminar tissue of equine submitted to intraluminal small colon obstruction

description: ABSTRACT The aim of this study was to evaluate the blood leukocytes and the MMP-2 and -9 expression in the hoof laminar tissue of horses undergoing intraluminal small colon obstruction. Laparotomy and the small colon obstruction was performed in eight healthy horses, inserting a ball in the intestinal lumen. The ball was inflated to 80 mmHg pressure and the occlusion was maintained for 4 hours. The blood was collectedBlood samples were taken before the obstruction (M0), immediately after intestinal clearance (M4), and every 12 hours until completeuntil 72 hours (M12, M24, M36, M48, M60 and M72). The hoof biopsies were performed at M0, M4, and M72 and the samples were subjected to zymography analysis. There was an increase in leukocytes in M12 and M24, due to the increase in segmented neutrophils and band neutrophils, which decreased as of M36. According to zymography technique not observed changes were not not observed in MMP-2 and -9, possibly due to the low intensity of the small colon lesions. Wherefore, it is concludedIn conclusion, that the inflammatory changes resulting from small colon obstruction were not enough to cause changes in the expression of MMP-2 and -9 in the hoof laminar tissue.

title: THE DISAMBIGUATION OF HOMONYMOUS WORDS IN SENTENCES BY BRAZILIAN PORTUGUESE-LIBRAS AUTOMATIC TRANSLATION APPLICATIONS

description: ABSTRACT This study analyzes the Automatic Translation (AT) of homonymous words isolated and inserted in sentences, produced by Hand Talk and ProDeaf Mobile applications, both automatic translators from Brazilian Portuguese to Brazilian Sign Language (Libras), once previous studies have pointed to the absence of disambiguation strategies, use of fingerspelling and translation errors. This is an exploratory qualitative research based on studies of the lexicon of Libras, Automatic Translation, Natural Language Processing and Disambiguation, whose purpose is to deepen initial findings, under the same theoretical bias, in order to propose improvements on the AT of Portuguese Language-Libras. Thus, this study analyzed the AT of 38 homonymous words isolated and contextualized in 38 sentence pairs (two distinct meanings in each sentence pair). The results revealed that in AT of isolated words the applications generate the translation of only one of the meanings of the homonymous words (HT: 89% and PDM: 63%). In sentences, the percentage of correct word meanings, in both applications, is lower (HT: 82% and PDM: 60%) than in AT per isolated word and even lower (HT: 13% and PDM: 11 %) in the disambiguation of homonymous words. The findings of this research indicate the need to improve the Natural Language Processing system of the applications for the disambiguation of homonymous words. It is inferred that a more adequate AT at the level of isolated word and sentence can offer users more analogous translations to Libras, as the natural and official language of the deaf community in Brazil.

title: Although it induces synchronized ovulation, hCG reduces the fertility of Santa Ines ewes submitted to TAI

description: ABSTRACT The aim of this study was to evaluate hCG treatment on ovarian response and on pregnancy rate using a 9-day oestrus synchronization protocol in Santa Ines ewes. On a random oestrus cycle day, ewes received an intravaginal progesterone device (Primer-PR®, Tecnopec, Brazil). Nine days later (Day 9), 30µg of d-cloprostenol (Prolise®, Syntex, Argentina) and 250IU of eCG (Folligon®, Intervet, Brazil) were administered and the progesterone device was removed. This moment, the ewes were randomly assigned on two groups: Control Group and hCG Group. In the hCG Group, the ewes received 500IU of hCG (Vetecor®, Hertape-Calier, Spain) 24h after device removal. In the Control Group, the ewes did not receive any ovulation inductor. Control and hCG Groups ewes were inseminated 60h and 48h after device removal, respectively. There was no difference between the groups regarding the first ovulatory follicle diameter and the second ovulatory follicle. hCG Group ewes had shorter interval between device removal and ovulation (Control: 79.9±15.4h and hCG: 54.7±4.9h; P=0.001) and more synchronized ovulations. However, the treatment with hCG decreased the pregnancy rate after TAI (P=0,009). In conclusion, hCG administration improves ovulatory synchronisation, but causes a decrease in the pregnancy rate.

title: Some macro and trace elements in various tissues of Van fish variations according to gender and weight

description: ABSTRACT Van fish is a fish that can live in soda water at pH 9-10. Van fishing area is a very important source of protein for the people. The variations in tissue metal levels according to gender and weight in Van fish (Alburnus tarichi, Güldenstadt 1814) were studied. This study was conducted for the first time in Van fish. Which it is very important for living organisms Calcium(Ca), magnesium(Mg), sodium(Na), potassium(K), cobalt(Co), chromium(Cr) and lithium(Li) elements levels in the muscle, liver, gill, gonad, and brain tissues of Van fish were investigated by using inductively-coupled plasma-optic emission spectroscopy (ICP-OES). The results were evaluated in two groups as macro-elements(Ca, Mg, Na, K) and trace-elements(Co, Cr, Li). Cobalt concentration in brain tissue was found to be higher than those in other tissues. Also, male fish had higher metal concentrations than female fish and their metal levels in brain and gonad tissues varied with their weight (P&lt;0.05). This study shows that consumption of Van fish can be consumed to supply some necessary minerals required for a healthy nutrition.

title: Fish products made from trawl fishery waste: physical, chemical, microbiologic, and toxicological analysis

description: ABSTRACT Seafood products represent an important source of proteins and minerals as well as polyunsaturated fatty acids. However, its consumption in Brazil is very low in comparison to other kinds of meat. This may due to lack of skill in its preparation, making immensurable the importance of the search for new ways to market it, such as ready-made or semi-ready to serve products. The trawl fishery method often accidentally captures a variety of species, composed basically of low commercial value and size. Such catches are called “second-hand catch”. With this in mind, this paper has as its main objective de development of two products: fish meatball and kibe, using what is considered accidental catches in the trawl fishery industry done on Rio de Janeiro's offshore as the raw material. The taxonomic identification of the species resulted in the species, Red porgy (Pagrus pagrus), Argentine croaker (Umbrina sp.), Atlantic bigeye (Priacanthus arenatus), Black cusk-eel (Conger sp.), Cusk-eel (Genypterus brasiliensis) and Blackfin goosefish (Lophius gastrophysus). The dry material of the raw product was 31.20±1.30%, in the raw meatball and kibbeh the values was 37.90±1.10 and 32.10±1.10, respectively, in the baked product the results was 33.40±1.20 and 34.20±1.00 (kibbeh and meatball). The ash content in the pulp was 1.5%, for the raw kibbeh and meatball, the amounts of ash were 2.55±0.05 and 1.47±0.05, respectively. For baked goods results were 1.87±0.05 for the kibbeh and 1.92±0.05 for the meatball. The measured lipid levels in the pulp was 4.80±0.30%. In respect, raw kibbeh and meatball, the percentage of lipids were 4.20±0.80 and 4.20±0.60, respectively. For baked goods was 4.50±0.60 for the kibbeh and 4.40±0.60 for the meatball. The protein level presented in the raw material was 15.60±1.04%, to the raw kibbeh and meatball was 17.80±2.16 and 14.90±2.12 and for the baked goods 15.10±2.10 both. Soluble nitrogen compounds shows values of 285mg/100g in the raw material, in the kibbeh NNP 291mg/100g and the meatball NNP 294mg/100g. The results of the total count of psychotropic remained below 7.0 log CFU/g, for standard count of aerobic microorganism plates. Fecal coliform bacteria, Salmonella, and Staphylococcus aureus were not present . The levels of histamine and sulfur basic compounds (H2S) were not detected in the samples.
