Por uma visão discursiva do fenômeno da hesitação

Partindo de questionamentos ao modo como a literatura trata o fenômeno hesitativo, defendemos, neste trabalho, a hipótese de que as hesitações funcionariam como marcas de momentos de tensão entre elementos lingüístico-discursivos. Buscando confirmá-la, analisamos material extraído de sessões de conversação de um sujeito com doença de Parkinson e de um sujeito sem patologia neurológica. Verificamos, nos vínculos entre as marcas de hesitação e os trechos de fala que a elas se relacionavam: (a) se ocorria contenção da ou abertura para a deriva; (b) se as ações sujeito-língua ocorriam antecipadamente ou reparando a deriva; e (c) se as tensões predominavam no eixo sintagmático e/ou paradigmático da linguagem. Essa observação permitiu-nos conjecturar: (I) que, no processo hesitativo, podem figurar uma contenção da deriva e/ou uma abertura para a deriva; (II) que as hesitações se constituem em pontos de deriva/ancoragem de ações sujeito-linguagem de reparação e/ou antecipatórias; (II) que subsistemas lingüístico-discursivos funcionam sob diferentes relações de predominância no acontecimento do fenômeno hesitativo.

Effect of sex and seasons of the year on hematologic and serum biochemical variables of captive brown brocket deer (Mazama gouazoubira)

The Brown brocket deer (Mazama gouazoubira) is the most common free-living and captive deer in South America, especially in Brazil, and has great ecological and scientific significance. However, data on hematological and biochemical parameters in brown brocket deer are scarce. The goal of this study was to establish reference ranges for hematological and biochemical parameters of Mazama gouazoubira, comparing differences during the seasons of the year and between sex. Blood samples from ten adult healthy brown brocket deer (6 female and 4 male) were collected during daytime, monthly, during 12 months. The animals were maintained in individual stable, protected from noise and fed ad libitum with commercial ration and green fodder. For blood collection, animals were submitted to physical restrain for no longer than 2 minutes. The following parameters were determined: red blood cell count (RBC), haemoglobin concentration, packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), white blood cell count (WBC), platelet count, enzyme activity of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) and serum levels of alkaline phosphatase (ALP), creatine kinase (CK), total protein (TP), albumin, cholesterol, total calcium, ionic calcium, sodium, potassium, magnesium, triglycerides, creatinine and urea. Values were compared according to season and sex. RBC count, WBC count and MCV suggested seasonal influence. Haemoglobin concentration, PCV and MCV were influenced by sex. Serum concentration of total calcium, ionic calcium, sodium, potassium and magnesium were influenced by season. Serum magnesium was also influenced by sex. The blood parameters herein reported may be useful as reference values for diagnostic and prognostic purposes in captive brown-brocket deer.

Avaliação da influência do estresse em modelo experimental de colite por administração de Ácido Trinitrobenzenosulfônico (TNBS) em concentração subinflamatória

Inflammatory bowel disease (IBD) is a chronic and relapsing disease caused by exaggerated response of the immune system. It represents a significant health problem by limiting the quality of life and being the main risk factor for colorectal cancer. Despite of its importance, the high worldwide incidence and being the object of research for several decades, the etiology remains unknown. Studies indicates an interaction between genetic and environmental factors which together with the intestinal microbiota, leads to an uncontrolled immune response. One of the aggravating environmental factors often discussed is stress, as the daily life of the population in general is increasingly rushed. In order to demonstrate the influence of stress on IBD, this study aimed to standardize an experimental model of colitis induced by instillation of a trinitrobenzene sulfonic acid (TNBS) noninflammatory concentration plus exposure to stress that intensify the inflammation. Therefore, an experiment was done to determine what would be the noninflammatory concentration. In this step, four different concentrations of TNBS (1, 6, 12.5 or 40mg/ml) were tested and the lowest concentration capable of inducing a noninflammatory response in the gut was defined as 1 mg/ml. Then, a second experiment was performed which induced colitis and exposed the animals to restraint stress. The results, however, showed that this stimulus was not enough to exacerbate the damage caused by the 1 mg/ml concentration of TNBS in the colon. With some changes in the protocol, the third experiment associated cold and restraint, as well as changes on the day of euthanasia, which occurred immediately after the stress session. The results of myeloperoxidase activity measurement were unexpected due to the noninflammatory concentration of TNBS caused an intestinal inflammation similar to the concentration of 40 mg/ml. However, the results of glutathione quantification and the corticosterone ...

Comparação de métodos de dimensionamento de muros em solo reforçado através de programas computacionais

Dans ces dernières années, plusieurs méthodes de dimensionnement d'ouvrages de soutènement en sol renforcé ont été développés, mais la doute c’est où l'utilisation de chacun d'eux se révèle plus avantageux? Ce travail a été conçu avec l'objectif de faire une étude d’un cas historiques d'un mur en remblais renforcé avec parement végétal de 27,6 mètres de haut, dont la conception a été analysé en utilisant une méthode de calcul et des logiciels informatiques spécifiques à l’utilisation dans le domaine géotechnique. Avec cette étudesont attendus de résultats capable de présenter les principales caractéristiques de chaque méthode et où il peut le mieux être appliquée

Levantamento e análise de técnicas utilizadas nas operações de emergência de derramamento de óleo em ambientes costeiros e fluviais

This present paper aims to identify the main response techniques for coastal and fluvial environments and analyze impacts on the application of these techniques. The literature review allowed us to understand since the establishment of first environmental sensitivity index map, in coastal and fluvial environment, until the possible impacts generated by the application of cleanup techniques in both environments. Studies related to freshwater environment are less common compared to coastal environment. For both environments the same techniques may be employed, as well as containment and recovery, or removal of oil in the affected areas. The most serious environmental impacts generated are due to the poor choice of technique to be applied or the lack of training of the cleaning crews. In Deepwater Horizon accident, Gulf of Mexico, 2010, application of dispersants, resulted in a mixture of oil and dispersing 52 times more toxic than the oil itself. In Brazil, the technique of vegetation removal by the cleaning staff in the accident on the river Guaecá, 2004, resulted in unnecessary elimination of vegetation, increasing the volume of waste. It was concluded that the freshwater environment often suffer more impacts by applying the techniques, once is necessary to access the banks, which normally have more vegetation and organisms than shoreline of coastal environment

Manejo pré-abate de bovinos

The pre-slaughter moment begins with the animal´s loading on the farm and ends up in its drain. It is a period in which the animal is under physical stress caused by hunger, thirst, fatigue, injuries, and extremes of temperature and psychological stress, due to restraint, handling, innovation and fear. Stress and inappropriate handling bring bad consequences for the final product´s quality, requiring better handling conditions, facilities and equipment. Examples of consequences of mishandling: meat with abnormal color, DFD meat (dark, firm and dry), reduced product´s shelf life, bruises and broken bones in carcasses. The operators should be trained and oriented on the basic principles of biology, behavior and management of cattle. At every step of the pre-slaughter moment, the animals should be handled calmly and quietly to avoid excitement and stress. Operators should avoid shouting, whistling or any noise since cattle have very sensitive ears and can become stressed. If the animals refuse to move, the cause of the problem should be determined
