Rock-forming mineral stability is comparedwith groundwater composition of certain ultrabasic massifs of Rio Grande do Sul, Brazil, under subtropical weather conditions. In this sttidy physicochemical equilibrium calculations are made, relating minerals to their hydrolisis solutions as well as relating primary to secondary minerals. These calculations permit one to draw straight line graphics that correspond to each chemical reaction and to limit stability areas whose coordinates are Mg and H4SiO4 concentrations. Plotted in these graphics are the mean compositions of the groundwater for each season of the year which indicate the relative stability scale of the different minerals and the mineralogical compounds that are in equilibrium with the environmental conditions.

In this study, it was discussed the efficiency criteria in each of the elements that compose a central pivot, and this analysis was applied to two sets of systems located in regions of Cruz Alta and Santo Augusto, state of Rio Grande do Sul, Brazil. The methodology used combines water and energy assessment through an indicator called Normalized Specific Consumption in Irrigation (C ENI), allowing thus a comparison between equipment and projects. The C ENI in Cruz Alta region showed 72% of the equipment above the standard (8.68 kWh mm-1 ha-1 100m-1), and in Santo Augusto region 64.28% with consumption above the standard. The mean irrigation efficiency for Cruz Alta region was 29.85%, with standard deviation of 5.41%, and for Santo Augusto region, it was 29.02%, with standard deviation of 5.15%.

Data are presented here on the effect of applications of 2,4-D and maleic hydrazide to sugarcane at intervals prior to harvesttime. Field experiments were conducted at Río Piedras in northern Puerto Rico and at Colonia Río Grande, between Caguas and Gurabo, in east-central Puerto Rico. Daily fluctuations in Brix, polarization, purity, and available 96° sugar percent cane were followed for 46- and 72-day periods, respectively. No significant differences were observed between the mean available 96° sugar percent cane that could be ascribed to treatments. Seasonal variations and variations attributable to weather conditions were rather important factors at both locations.

ABSTRACT Changes in the frequency of occurrence of extreme weather events have been pointed out as a likely impact of global warming. In this context, this study aimed to detect climate change in series of extreme minimum and maximum air temperature of Pelotas, State of Rio Grande do Sul, (1896 - 2011) and its influence on the probability of occurrence of these variables. We used the general extreme value distribution (GEV) in its stationary and non-stationary forms. In the latter case, GEV parameters are variable over time. On the basis of goodness-of-fit tests and of the maximum likelihood method, the GEV model in which the location parameter increases over time presents the best fit of the daily minimum air temperature series. Such result describes a significant increase in the mean values of this variable, which indicates a potential reduction in the frequency of frosts. The daily maximum air temperature series is also described by a non-stationary model, whose location parameter decreases over time, and the scale parameter related to sample variance rises between the beginning and end of the series. This result indicates a drop in the mean of daily maximum air temperature values and increased dispersion of the sample data.

ABSTRACT: Hydatidosis and cysticercosis are parasitoses caused by the larval forms of the cestodes Equinococcus spp. and Taenia spp., which belong to the Taeniidae family. Their definitive hosts are canids and humans, respectively, with ruminants as the intermediate hosts and humans as an accidental host of both diseases. These parasites are responsible for large economic losses in slaughterhouses due to condemnation of carcasses and by-products. The present study reports the mean incidence rates of hydatidosis and cysticercosis in cattle slaughtered in the southern region of Rio Grande do Sul state, Brazil. The incidence rates observed between 2013 and 2016 were 19.96% and 0.9%, respectively, with decreased tendency of occurrence of both diseases in those years. Despite the downward tendency of the diseases, hydatidosis presented high incidence. Hydatidosis performance over the years was characterized by significant increase in the number of cases, followed by marked decrease. Cysticercosis presented a decrease in number of cases at the beginning and the end of each year. These diseases have a significant socioeconomic impact as they are responsible for large losses in the livestock industry, due to reduced productivity and carcass condemnation, and represent a risk to public health.

ABSTRACT This study sought to evaluate the occurrence of lesions suggestive of hydatidosis, cysticercosis, and tuberculosis in animals slaughtered under sanitary inspection of the Divisão de Inspeção de Produtos de Origem Animal (DIPOA), in the state of Rio Grande do Sul. Condemnation data between the years 2009 and 2017 were obtained from Secretaria da Agricultura Pecuária e Irrigação (SEAPI) and presented according to the administrative regions established by SEAPI. In that period, 7,509,544 cattle were slaughtered and condemnations occurred in all regions of the state at varying levels. The mean condemnation values showed the presence of hydatidosis in 523,399 (6.97%), cysticercosis in 92,277 (1.23%), and tuberculosis in 10,595 (0.14%) cattle carcasses. The mean values of hydatidosis diagnoses were higher in the regions of Alegrete (14.19%), Bagé (19.62%), and Pelotas (17.71%). The regions of Osório (1.86%), Santa Maria (2.10%), and São Luiz Gonzaga (1.83%) had highest rates of cysticercosis condemnations. All regions maintained an average bovine tuberculosis diagnosis rate of less than 1% and Estrela region had the highest index (0.70%). Results showed that the three diseases occurred in all regions of the state, the average prevalence rates in each region are variable, and distribution seems to be regionalized. This knowledge contributes to the plans for controlling these diseases, which are zoonoses that cause economic losses to the productive sector.

O objetivo do estudo foi identificar o comportamento financeiro dos estudantes de uma universidade no noroeste do estado do Rio Grande do Sul, avaliando as principais razões das dívidas das pessoas, aplicando uma survey com 160 alunos do curso de administração. Foram utilizadas técnicas de média aritmética e testes de diferença de média. As diferenças de média apontaram diferentes significados de propensão ao endividamento por gênero, idade, estado civil, filhos e renda. Os resultados mostraram-se significativos referentes ao perfil pela dívida por falta de planejamento, alta propensão ao consumo, falta de desconto à vista, empréstimo do nome e por acesso ao crédito. Os procedimentos apontaram que os respondentes gastam menos ou igual à renda que recebem, possuem dívidas, porém, não estão atrasadas e são mais cautelosos ao investir, uma vez que não desejam assumir riscos.Palavras-Chave: Endividamento. Estudantes. Dívidas. Propensão. Administração.Student's financial behavior: assessment of the property to the debtABSTRACTThe objective of this study was to identify the financial behavior of students from a university in the northwest of Rio Grande do Sul state, evaluating the main reasons for the debts of the people, applying a survey with 160 students of the administration course. Arithmetic mean and difference mean tests were used. The differences in the mean showed different meanings of debt propensity by gender, age, marital status, children and income. The results were significant in relation to the debt profile due to lack of planning, high propensity to consumption, lack of cash discount, name loan and access to credit. The procedures indicated that respondents spend less than or equal to the income they receive, have debt, but are not late and are more cautious when investing, as they do not want to take risks.Keywords: Indebtedness.

This is the first report of a species of Echinuria Soloviev, 1912, on anatid hosts in South America, causing granulomas. It is also the first detailed description and record of a species of Echinuria, for South America in the Rosy-billed Pochard, Netta peposaca (Vieillot, 1816). Fifty-two rosy-billed pochards were examined for helminths in the Municipalities of Santa Vitória do Palmar (locality of Fazenda Sossego) and (locality of Ponta da Antena), State of Rio Grande do Sul, Brazil, and Alvear, Province of Corrientes, northern Argentina. Samples were obtained from 2003 to 2004. After the catch each bird was immediately frozen with dry ice. Prior to necropsy birds were sexed, weighted, measured, and the state of maturity (juvenile or adult) determined, based on the presence or absence of a bursa of Fabricius. The granulomas with the nematodes were found in the proximal esophagus at the junction with the proventriculus. Two birds had one (fistulated) and two granulomas, respectively. One of the birds was from the wintering grounds along the coastal region in the State of Rio Grande do Sul, southern Brazil. The other, from one of the breeding grounds in northern Argentina, was captured before the trip to the wintering grounds along the migratory flyway. Prevalence was 3.8% while the mean intensity of infection was 7.2. Morphometry of males and females and the comparison with previous descriptions and illustrations allowed the identification of the present specimens as E. uncinata.
