The State of Rio Grande do Sul is a major producer of grapes in Brazil, highlighting the Serra Gaúcha as the main producing region. In the pursuit of good quality in grapes it is essential the control of pests, especially insects. This study highlights the incidence of wasps, which cause serious damage at harvest time. This study aimed to characterize the community of social wasps (Hymenoptera, Vespidae) through faunal analysis and to examine the relationship of these insects with injuries to the grape berries in vineyards of Bento Gonçalves, Rio Grande do Sul State. Therefore, active search were made in January and February 2014, followed by analysis of frequency, constancy, abundance, dominance and diversity. Ten species of wasps were able to use grape berries as food. The two dominant species were Polybia ignobilis and P. minarum, however, Synoeca cyanea has greater ability to break the intact berries. Other three species, Polistes cavapytiformis, P. versicolor and Brachygastra lecheguana, were also able to break the skin of grapes, but of damaged berries.

Morphological, particularly textural, discontinuities between horizons increase soil erodibility in Depressão Central, Rio Grande do Sul State (Brazil). Characterization of such discontinuities would help to understand landscape evolution and to model near-surface hydrology. The objective of this research was to explore the relationship between morphological discontinuity and deposition of transported materials during pedogenesis. Transported material was meant to be mineral particles found in the soil profile, transported probably by water or gravity, that were not present neither in the parent material nor derived from it. Five soils of this region (two Alfisols, two Ultisols and one Mollisol) were sampled and morphological, sand grain size statistics, chemical and mineralogical analyses were used to search for evidences of deposition of transported materials. Two soils had abrupt textural change but no evidence of deposition of transported materials, two soils had less contrasting morphology and some characteristics that are possibly related to deposition, and one soil had no morphological discontinuity, but had deposition of material enriched in magnetite-maghemite in the sand fraction of the A horizon. Therefore, there were no relationship between morphological discontinuity and deposition of transported materials for these profiles in the Depressão Central.

ABSTRACT Although several studies have evaluated the intensity-duration-frequency relationships of extreme rainfall events, these relationships under different seasonal conditions remain relatively unknown. Thus, this study aimed to determine whether the intensity-duration-frequency relationships obtained seasonally from the rainfall records in the winter and summer represent the maximum rainfall events for the city of Pelotas, Rio Grande do Sul state, Brazil. Pluviographic data from 1982 to 2015 were used to create two seasonal series: one for the summer from December 21 to March 20 and the other for the winter from June 21 to September 22. These seasonal relationships were compared with the annual pluviographic data. The intensity, duration, and frequency relationships obtained from the summer rain data adequately represented the maximum rainfall in Pelotas, Rio Grande do Sul state, Brazil. The maximum intensity values of rainfall obtained from the relationship of intensity, duration, and frequency for the winter did not adequately encapsulate the occurrence of rain with greater intensities.

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.

O objetivo deste trabalho foi avaliar a relação entre o fenômeno El Niño Oscilação Sul - ENOS e o rendimento de grãos de soja e de milho no Rio Grande do Sul e verificar a hipótese de que os eventos El Niño são favoráveis e os eventos La Niña são prejudiciais ao rendimento de grãos das culturas. Foram utilizados dados de rendimento de grãos dos anos agrícolas de 1974/75 a 2016/17, e relacionados com as ocorrências de eventos ENOS. Foram analisados os dados de rendimento observados na colheita e os dados estimados com a remoção da tendência tecnológica. Os resultados mostraram que não houve diferença significativa do rendimento médio de grãos de soja e de milho na comparação entre os eventos ENOS. Palavras-chave: El Niño, La Niña, safras agrícolas. Abstract – The objective of this work was to evaluate the relationship between the El Niño Southern Oscillation (ENSO) phenomenon with the grain yield of soybean and maize in Rio Grande do Sul state, Brazil and to verify the hypothesis that the El Niño events are favorable and the La Niña events are harmful to the culture’s grain yields. Were used data from the agricultural years of 1974/75 to 2016/17, and related to the occurrence of ENOS events. We analyzed income data observed at harvest and estimated data with technological tendency was removed. The results showed that there was no significant difference in the average yield of soybeans and corn in the comparison between events.

The objective of the work is to establish the characterization of the auditory disability and its relationship with resilience at the Technical University of Manabí. The article shows a conceptual analysis related to the inclusion and social integration of disabled students. Based on the fact that the person with disabilities grows and develops in the same way as that of people without disabilities and what usually happens is that disabled people are rejected and discriminated against based on a prefabricated and erroneous conceptualization of these people. The results associated with the application of the SV-RES test prepared by the researchers are shown (Saavedra & Villalta, 2008b). Characterization of the auditory deficit is made in the students, and the limitations that derive from it are pointed out. We analyze the particularities related to communication with students who have a hearing disability and resilience in this type of student, where some personal highlights that in this sense constitute an example of resilience. Finally, the results related to the study of the relationship between students' hearing disability and the level of resilience dimensions are shown.

(BJ6.350)Those who discard their weapons and surrender their persons, I will let live. Like a lenient master in a household, I will punish the incorrigible but preserve the rest for myself.So ends Titus' address to the embattled defenders of Jerusalem in the sixth book of Josephus'Jewish War(6.328-50). It is the most substantial instance of communication between Romans and Jews in the work. Titus compares himself to the master of a household and the Jewish rebels to his slaves. Is this how we expect a Roman to describe empire? If not, what does it mean for our understanding of the politics of Josephus' history? The question is particularly acute given that this is not just any Roman but Titus himself: heir apparent and, if we believe Josephus, the man who read and approved this historical account. It is thus surprising that, while the speeches of Jewish advocates of submission to Rome such as Agrippa II (2.345-401) and Josephus himself (5.362-419) have long fascinated readers, Titus' speech has received little or no attention. Remarkably, it is not mentioned in any of three recent collections of essays on Josephus. This paper aims to highlight the rhetorical choices that Josephus has made in constructing this voice for Titus—particularly his self-presentation as master—and the interpretive questions these raise for his readers. It should go without saying that the relationship of this text to anything that Titus may have said during the siege is highly problematic. (Potentially more significant, but unfortunately no less speculative, is the question of how it might relate to any speech recorded in the commentaries of Vespasian and Titus that Josephus appears to have used as a source.) What we have is a Josephan composition that is embedded in the broader narrative of theJewish War.

Sinopse: Em meio ao colorido de goiabas, batatas e flores mais que cheiros e sabores, descobrir pessoas. Agricultoras e agricultores que com suas histórias e lutas, estão representados nas varandas e nas mesas da cidade. Trazer a imagem não de uma feira, mas de cada pessoa que diariamente se dedica ao cultivo e à produção de alimentos. Encontrar o rosto e as escolhas de outros modos de fazer agricultura, de outros modos de se alimentar. De assentados e suas lutas pela preservação de sementes crioulas, de jovens universitários e sua determinação em permanecer no campo e de fumicultores aposentados dispostos a limpar suas terras dos venenos de mais 30 anos de cultivos agressivos, é feita a Feira Sabores da Terra. Feira da agricultura familiar do município de Canguçu, Rio Grande do Sul, que acontece todas as segundas-feiras à tarde e reúne cerca de 18 produtores. Em um pavilhão de madeira no centro da cidade são expostos doces coloniais, panificados, frangos congelados, farinhas, feijões, legumes, verduras, frutas e flores, em variedade conforme a estação do ano. Produtos que são vendidos entre boas conversas, rodas de chimarrão e é claro, uma melancia bem gelada ou uma deliciosa rapadura. Para a permanência e continuação da feira, que se realiza há pouco mais de um ano, os feirantes têm enfrentado e superado dificuldades. A distância de suas propriedades até a cidade, muitas das vezes são mais do que duas horas de viagem. A demanda, pelos consumidores, por produtos conforme padrões estéticos dos alimentos produzidos com veneno. O cansaço de mãos que, com mais de 40 anos de trabalho, ainda enfrentam a roça durante toda a semana e o frio, a chuva e o calor de uma feira praticamente ao ar livre. O conciliar o trabalho agrícola e a feira com os estudos, cujo acesso limitado pela distância das universidades, das oportunidades de estágios e pela dificuldade de ascender ao ensino público superior. Apesar de tão próximos, rostos e mãos muitas vezes invisíveis em escolhas alimentares. Gente que oportuniza uma alternativa à alimentação. Alimentação proveniente da relação de mulheres e homens com a terra, de suas sabedorias e ações. Feira Sabores da Terra, um ponto de aproximação entre o campo e a cidade, entre o cultivo e o alimento, entre o cuidado e o sabor. De agricultoras e agricultores e seus feijões, morangos e biscoitos. Este ensaio fotográfico é parte da agenda de pesquisa “Saberes e Sabores da Colônia”, desenvolvida no âmbito do Grupo de Estudos e Pesquisas em Alimentação e Cultura (GEPAC) e vinculada ao Bacharelado e ao Programa de Pós-Graduação em Antropologia da Universidade Federal de Pelotas. Synopsis: In the middle of colored places with guava , potatoes and flowers more than smells of flavors, we discover people. Farmers, with your stories and struggles, are represented on the balconies and tables of the city. Representing the image of each person that daily is dedicated to the cultivation and food production, not just the image of a fair is much more than that. Find the face and choices of other ways of doing agriculture and others ways of feeding. From the land reform settlements and their struggles for the preservation of native seeds, of university students and their determination to remain in the field and retires tobacco growers willing to clear their land of the poisons of another 30 years of aggressive crops, is made the Flavors of the Earth Fair. Family Agriculture Fair, in the Canguçu City in Rio Grande do Sul, Brazil, of what happens on every Monday afternoon and brings together about 18 small farmers. In a wooden pavilion in Downtown city are exposed colonial sweets, bakery products, quick-frozen, flours, beans, vegetables, fruits and flowers in variety according to season. Products that are sold as God´s taste is of course chimarrão, and watermelon ice-cold or a delicious rapadura. For the permanence and continuation of the green fair, been held little more than a year ago, the small farmers have had and overcome difficulties. The distance of their properties of the Downtown , often last more than two hours of the trip. The consumer demand by products according to aesthetic standards of foods produced with venom. The fatigue of hands, still for more than 40 years of work, are still facing small farm during the days in a cool, rain and heat weather and the a fair still open. To reconcile agricultural work and the fair with studies, to which access is restricted by distances from universities, internship opportunities, and the difficulty of access to higher public education. Although close, often invisible faces and hands in food choices. People who offer alternative food. Food derived from the relationship of men and women to the land, of his wisdom and actions. Flavors of The Hearth Fair, a point of approximation between the countryside and the city, between the crop and the food, between care and taste. Of farmers and agriculturists and their beans, strawberries and biscuits. This photo essay is part of research agenda “Knowledge and tastes of the agricultural colony”, developed in the framework of the Group of the Studies and Researches in Food an Culture (GEPAC) and linked to the Bachelor’s and the Postgraduate Program In Anthropology of Federal University of Pelotas.

The wax hydrocarbon fractions of native Butia and Syagrus species collected from Palms in different regions of the of Rio Grande do Sul state (Brazil) and in Rocha (Uruguay) were analyzed to evaluate their potential as chemotaxonomic markers. The wax was extracted with chloroform and the resulting wax was fractionated by preparative TLC. The hydrocarbon fractions were analyzed by GC-MS. Statistical analyses were completed with the Statistica 5.0 program. The total crude wax yields averaged 0.31% w.w-1 dried leaves for Butia samples and 0.28% for Syagrus samples. The linear hydrocarbons represented on average 15% of the total waxes in the case of Butia samples and 13.7% in Syagrus samples. Hentriacontane and triacontane were the main components of all samples. The comparison of the means showed significant differences among Butia and Syagrus samples, and amongst Butia samples collected in different localities. In the case of the Syagrus collections no consistent groupings could be made. In the case of Butia samples the formation of three groupings could be observed, which were consistent with the species described for their geographical distribution. These results are discussed in the paper.

AbstractHow can we explain the fact that the Anglican Covenant divides people of equal integrity and comparable wisdom around the world? We need to ask whether we have correctly understood both the ecclesiology of the Anglican Communion and the terms of the Covenant. What is implied in being a Communion of Churches, where the churches are the subjects of the relationship of communion (koinonia)? What does the Covenant commit its signatories to and, in particular, what does it say about doctrinal and ethical criteria for communion? Is it legitimate to apply biblical covenant language, in which the covenant relationship is between God and Israel, to relations between churches? By addressing some of the concerns of those who oppose it, a case is made in favour of the Covenant and some reassurances are offered. In conclusion, the mystical dimension of being in communion is affirmed.

The assay was conducted in Pelotas, Rio Grande do Sul-Brasil, to compare the effect of used engine oil with to paraquat (Gramoxone) applied during the physiological maturition of soybean seeds (Glicyne max (L.) Merrill), Bragg variety. The oil doses were 5.3, 8.5 and 12 l/ha. The desiccation intensity was determined and 30 pods per plot were periodically collected to follow the humidity content of the seeds, to 18%. The humidity was later reduced to 10.5 +0.5 and 2.0 kg of seeds were stored, in cotton bags,during 6 months under the environmental conditions at the Centro de Entrenamiento de Semillas of the Federal University of Pelotas. The seeds were subjected to germination, vigor and phytosanitary tests at harvest time and after 3 and 6 months of storage. Under the conditions of this trial, the doses of 12 l/ha of oil and 2 l/ha of paraquat: a) act as desiccants for soybean plants, b) favors the production of seeds with better viability and vigor after 6 months of storage and c) guarantied better sanitary seed quality after 6 months of storage.
