title: Sodium hypochlorite for removal of the sarcotesta from newly extracted and stored papaya seeds

description: Abstract: The objective of this study was to evaluate the effect of sodium hypochlorite on removal of the sarcotesta and the germination process of newly harvested papaya seeds before and after storage for 44 days. Nine treatments were evaluated using a completely randomized design with six treatments in a split plot arrangement and three additional treatments (control), each treatment with eight replications. The plots consisted of methods for breaking dormancy: M1 - sieve method + drying to 7%, M2 - sieve method + drying to 7% + NaOCl, and M3 - NaOCl + drying to 7%. The split plots consisted of different storage periods (0 and 44 days). The three additional treatments consisted of A - NaOCl at 6% for 12 hours, B - sieve method, and C - intact seeds in running water for 24 hours. Germination and the first count of germination were evaluated. Results showed that sodium hypochlorite is effective in removal of the sarcotesta, but there is a negative effect on germination. Storage for 44 days also had a negative effect on germination. Removal of the sarcotesta by the sieve method followed by drying to 7% moisture content was effective in promoting germination of papaya seeds.

title: The federal government’s voluntary transfers to municipal solid waste management: a study of the Metropolitan Region of São Paulo

description: Abstract The aim of this study is to analyze the federal government’s voluntary transfers to programs and actions related to municipal solid waste management (MSWM), providing results of municipalities in the metropolitan region of São Paulo. The methodological strategy was the qualitative exploratory research. Secondary data were obtained from documents and official sources, especially from the Pluriannual Plans, the Transparency Portal and the Agreements Portal. It was found that the concentration of such transfers was precisely on municipalities with high and medium GDP per capita. Moreover, low efficacy was observed in the use of federal resources, which can be attributed to a limited control of the voluntary transfers and of information coordination by the implementing bodies.

title: The role of bioethics in animal ethics commissions

description: Abstract Guidelines for the use of animals as experimental models transposed bioethics area focusing on the legal area, wich brought the benefit of standardization of physical and biological parameters, focused on animal welfare, but added bureaucratic and legal demands that occupied a reflection and discussion previously aimed at resolving ethical conflicts. This quantitative study aimed to characterize the opinion of members, coordinators and collaborators of ethics committees on how the use of Brazilian animals relates to those committees functioning. The 114 participants demonstrated adherence to the legislation but they pointed to an increase in potentially solving conflicts in the sphere of Bioethics. Although Bioethics has been identified as important for the proper functioning of committees, it has been defined in an unsatisfactory manner, evidencing the need to resume its role of guiding deliberations. This conclusion indicates the need to incorporate members with training in bioethics, invest in the frequent training of the collegiate and researchers involved in animal experimentation.

title: The economic viability of L-arginine supplementation in diets for sows in the lactation phase

description: ABSTRACT The objective of this study was to evaluate the economic viability of L-arginine supplementation in diets for sows during the lactation phase. A descriptive case study was carried out to identify the economic viability of the supplementation of L-arginine in the lactation ration, in relation to the control diet, on the productive performance of hyper prolific sows and their litters. The study was carried out on a commercial farm located in the state of Minas Gerais. It analyzed feasibility criteria such as the marginal physical product (MPPg) and gross margin (GM) in the scenario of technical and economic efficiency, which were compared to the GM in the control group. Technical efficiency was established at 0.71% of L-arginine in daily feed intake according to previous fieldwork by the authors, while economic efficiency obtained in this study was 0.43% supplementation. The relationship between the L-arginine price and the sale price of the piglets directly determined the economic viability, compared to the control group. Thus, initially considering the price of a piglet as R$ 9.76/kg, the cost of L-arginine should not exceed 6.61 times this value; that is, it is estimated at up to R$ 64.50. Therefore, at the final price of L-arginine of R$ 54.88, a piglet should be sold at a price of R$ 8.30/kg to make the supplementation of L-arginine in the diet of lactation-phase swine economically possible.

title: Assessment of land use/ land cover change in Tecolutla River Basin, Veracruz, Mexico; during the period 1994-2010

description: Studies related to changes in vegetation and land use cover have gained importance in environmental research, as they allow for the assessment of time-space trends in deforestation and environmental degradation processes, especially as caused by human activity. In this context, the main goal of this study was to evaluate the impact of human activity in the basin of the Tecolutla River, in Veracruz, Mexico during a 16-year period. Landsat satellite images were used for the years 1994 and 2010, distinguishing nine land use coverage classes: rainforest, forest, agricultural land, water, disturbed vegetation, urban settlements, grasslands, citrus crops and shrubs. Thematic maps were validated, yielding overall accuracies greater than 92% and Kappa coefficients of 0.89 and 0.91 for the 1994 and 2010 classifications, respectively. Analysis of the transition matrix revealed a trend of increasing areas related to human activity (agriculture and urban use) showing percentage changes of 28% and 67% within 16 years, respectively. Consequently, a decrease (-1.1% per year) in areas with natural cover, specifically forest and jungle, was observed. Similar findings were reported in works done at national and state levels, where the transition of natural cover by the increasing of anthropogenic activities has been proven. The results of this study are useful for future environmental development planning, land management planning and planning strategies for the conservation of the natural resources in the basin.

title: Protective action of nitric oxide in sesame seeds submitted to water stress

description: Abstract: The objective in this work was to investigate the effect of nitric oxide (NO) like protective agent in sesame seeds submitted to different osmotic potentials. The treatments, in total of eight, were water (control), water plus sodium nitroprusside (SNP) and the other treatments with PEG 6000 and PEG 6000 plus SNP: - 0.1 MPa, -0.1MPa +200 µM of SNP, 0.2 MPa, -0.2 MPa +200 µM of SNP, -0.3 MPa and -0.3 MPa, +200 µM of SNP. Were done the following determinations: germination, first count of germination, speed germination index, hypocotyl length, radicle length, dry mass of hypocotyl and radicle. It was quantified the activity of the antioxidative enzymes, superoxide dismutase, catalase, ascorbate peroxidase and total peroxidase. The experimental design was completely randomized with five replications. The water restriction reduced the germination of sesame seeds, however, the presence of nitric oxide (NO) due to the application of SNP, was beneficial, promoting increase in germination, vigor and seedlings. There was an increase of antioxidative enzymes activity in the period of 0 to 24 hours, demonstrating organization of antioxidative system in all long the time. The association of PEG 6000 to SNP, increased the activity of antioxidative enzymes, evidencing an efficient system of elimination of ROS formed during the exposition to water deficit.

title: Zircon U-Pb geochronology, Sm-Nd and Pb-Pb isotope systematics of Ediacaran post-collisional high-silica Acampamento Velho volcanism at the Tupanci area, NW of the Sul-Rio-Grandense Shield, Brazil

description: ABSTRACT: We present new U-Pb zircon ages and Sm-Nd-Pb isotopic data for volcanic and hypabyssal acid rocks from the northernmost exposure of the Acampamento Velho Formation in the NW portion of the Sul-Rio-Grandense Shield, Brazil. The first volcanic episode, grouped in the high-Ti rhyolites from the Tupanci hill, shows age of 579 ± 5.6 Ma, which is in agreement with the post-collisional Acampamento Velho Formation volcanism in the Bom Jardim Group of the Camaquã Basin. A poorly constrained age of 558 +/- 39 Ma was obtained for rhyolites from the low-Ti group at the Picados Hill, which may indicate a younger acid volcanism, or a greater time span for the volcanism of the Acampamento Velho Formation in southernmost Brazil. Regarding magmatic sources, Sm/Nd isotopic data coupled to Pb isotopes and a review of trace element geochemistry indicate different amounts of Paleoproterozoic (Dom Feliciano, Pinheiro Machado Suite) to Neoproterozoic (Rio Vacacaí terrane) lower crust melting. Our data, coupled with literature data, contribute to a better understanding of the stratigraphic evolution for the Neoproterozoic post-collisional volcanic successions of the Camaquã Basin in the Sul-Rio-Grandense Shield.

title: Embedment strength of dowels in wood specimens according to ABNT NBR 7190 (1997) and EUROCODE 5 (2004)

description: Abstract The study of connections for timber structures has been the subject of intense research in Brazil. This work aimed to study the embedment strength of connections made by steel pins (dowels) in specimens of reforested woods. Analytical and experimental evaluations were considered in this study. Initially, tests on specimens made from Pinus elliottii (Class C30) and Eucalyptus salligna (Class C50) woods with dowels, type 1020, with diameter of 6.35 mm (1/4") were performed. The tests were performed according to the ANBT NBR 7190 (1997) and Eurocode 5 (2004) Standards with subsequent comparison between the analytical and experimental results for embedment strengths. The values of the embedment strength showed that the Eurocode 5 (2004) Standard had greater agreement between experimental and analytical results when compared to the results of the ABNT NBR 7190 (1997) Standard.

title: Testicular biometric in Pantaneiros ovine fed with increasing levels of crude glycerin in the diet

description: SUMMARY Objective to evaluate the effect of the inclusion of levels of crude Glycerin in the feeding of lambs in the biometric characteristics and testicular histological. 24 lambs were neutered, not confined with 93.79 ± 5.73 days of age and body weight of 20.22 ± 2.84 kg. The treatments tested were: 0; 2.5; 5.0 and 7.5% of crude Glycerin injection in dry matter of diet in place of maize. The animals were slaughtered using the criteria in body condition score of 2.5 to 3.5 on a scale ranging from 1 to 5, and the variables evaluated were the initial weight, final weight, hot carcass weight, fat cover thickness, body condition, and the biometric parameters: testicular weight, scrotal perimeter in the scrotum, testicle weight left and right volume of right and left testicle, testicular testicular length width, seminiferous tubule diameter and height of germinal epithelium. There was no significant influence of crude Glycerin levels on any of the variables analyzed, also there was no correlation between the features assessed with body condition. Positive correlations were observed between hot carcass weight and fat thickness (r=0,57, p= p&lt;0,05)). There was positive correlation (r=0,55, p= p&lt;0,05)) between scrotal perimeter and body weight. The tubule diameter (r=0,47, p=p&lt;0,05) and height of the seminiferous epithelium (r=0,62, p=p&lt;0,05) were correlated with testicular volume. The inclusion of increasing levels of crude Glycerin in the feeding of lambs Pantaneiros, did not influence the biometric characteristics and testicular histométrics of animals.
