Monitoramento da din��mica costeira da praia de Ponta Negra

This dissertation includes the monitoring of coastal environmental dynamics at three points distinct from Ponta Negra beach, located on the South Coast of Natal, capital of Rio Grande do Norte, in the period June 2012 to May, 2013. For this, the following hypotheses were developed: Which actors morphodynamic and/or anthropogenic responsible for the changes in the study area? And yet, the configuration of the morphodynamic state of the beach, dissipative, reflective or intermediate? Faced with these questions , studies on the beach environment has its relevance as they may clarify the risks and responsibilities of anthropogenic intervention and also assist managers in more targeted action regarding the protection of praiais systems, since once committed, it is very difficult recover the environmental framework of the area, being greatly more feasible the development of multidisciplinary work plans that can guide human actions possible in search of an understanding to the harmonious interaction between society and the beach system. Its main goal is the understanding of the processes of coastal dynamics, methodological procedures that supported the implementation of this research were based on the object of study related literature associated with the collection of data resulting from beach profiles made monthly in spring tides (full moon), the hydrodynamic data and statistical quantification data (%) and size classification of sediment sediment after laboratory analysis. The results obtained from annual comparative tables of beach profiles, associated sedimentological analysis, indicated a positive sediment budget, tending to equilibrium for Point 01 and Point 02 negative. Have to Step 03 were added to the hydrodynamic data, which allowed also on a comparative framework, the perception of a depositional dynamics, with a tendency to decrease the accumulation of material at the end of the annual cycle. These data also allowed for the point 03, the calculation of the volume of material transported by the longshore current was around 104.280 m��/m, plus the Dean parameter which established a morphological state of the dissipative beach with specific prevalences for point 03. Thus, given the results presented in this work in a timely monitoring of coastal dynamics is expected that managers and public authorities can articulate multidisciplinary work plans, always aiming actions that seek understanding and effective commitment to the recovery of the harmonious interaction between society and Ponta Negra beach environment

Sorteio de domic��lios em favelas em inqu��ritos por amostragem

OBJETIVO: Identificar vantagens e desvantagens do uso de segmentos em rela����o ao sorteio feito a partir da lista completa de endere��os, para o sorteio de domic��lios em amostragem por conglomerados em m��ltiplos est��gios em favelas. PROCEDIMENTOS METODOL��GICOS: Estudo qualitativo realizado em quatro favelas sorteadas no Inqu��rito de Sa��de do Munic��pio de S��o Paulo, SP, 2008, nas quais foram aplicadas as duas t��cnicas. Foram realizados grupos focais com pesquisadores de campo - arroladores e entrevistadores do inqu��rito. Os conte��dos das conversa����es foram analisados, agrupados em categorias e organizados em n��cleos tem��ticos. AN��LISE DOS RESULTADOS: A utiliza����o de segmentos de domic��lios foi associada a numerosas vantagens e poucas desvantagens.

Leitura cr��tica da hist��ria: reflex��es sobre a hist��ria da matem��tica

Muitos elementos que fornecem informa����es para a escrita da hist��ria apresentam direcionamentos representativos de uma forma de pensamento, seja ela pol��tica, filos��fica ou de cunho social. Esses elementos s��o trabalhados para que se tenha uma vis��o espec��fica da hist��ria. O objetivo deste texto ��, por meio de alguns exemplos, discutir que existem diferentes formas de an��lise dos elementos que nos fornecem informa����es hist��ricas, com destaque para a Hist��ria da Ci��ncia, especificamente para a Hist��ria da Matem��tica. Quanto maior for a quantidade de informa����es sobre determinados acontecimentos hist��ricos, maior �� a possibilidade de se obter um encadeamento hist��rico, firmado em bases qualitativas, que sustente a informa����o adquirida. Se essas informa����es forem escassas, ou origin��rias de fontes duvidosas, as conclus��es hist��ricas referentes ao assunto tratado ficam fr��geis e pass��veis de diferentes e, muitas vezes, conflitantes interpreta����es. Neste texto, pretende-se apresentar alguns exemplos hist��ricos onde, por conta de poucas informa����es, ou informa����es distorcidas, a interpreta����o hist��rica �� pass��vel de mudan��as.

Efeito das condi����es ambientais no n��vel de ru��do emitido por leit��es

Objetivou-se, com este trabalho, avaliar a influ��ncia das vari��veis ambientais nos n��veis de ru��dos emitidos por su��nos e quantificar as faixas em dB comparativamente ��s condi����es de conforto t��rmico estabelecidas pela literatura. O experimento foi conduzido em c��mara clim��tica, onde foram alojados cinco leit��es em fase de creche, submetidos �� varia����o na temperatura ambiente de 20��C a 38��C e umidade relativa de 50% a 80%. Decibel��metros foram instalados para o registro dos n��veis de ru��dos e sensores dataloggers para os dados de temperatura e umidade relativa. O n��vel de atividade foi utilizado para quantificar a movimenta����o dos animais por interm��dio de an��lise de imagens. An��lises de correla����o e regress��o foram aplicadas nos dados para an��lise estat��stica. As vari��veis ambientais influenciam na emiss��o de ru��dos pelos leit��es quando expostos a diferentes condi����es t��rmicas. Os n��veis de ru��dos foram estabelecidos em faixas de acordo com a condi����o t��rmica a que animais foram submetidos. Para a condi����o de conforto (20 a 23��C), n��veis de ru��dos na faixa de 70 a 75dB; condi����o de alerta (23 a 30��C), n��veis de ru��dos na faixa de 60 a 70dB e para condi����o de estresse t��rmico (acima de 30��C), na faixa de 55 a 60dB.

FUNDAMENTOS: A Sociedade Brasileira de Dermatologia Regional do Estado de S��o Paulo (SBD-RESP), apoiada pela Funda����o Paulista Contra a Hansen��ase, e em a����o conjunta com os Servi��os de Dermatologia do estado de S��o Paulo, credenciados pela Sociedade Brasileira de Dermatologia, lan��ou a campanha SBD-RESP na Busca Ativa de Casos de Hansen��ase. OBJETIVOS: Auxiliar o Programa Nacional de Controle da Hansen��ase no controle da doen��a. M��TODO: Todos os Servi��os de Dermatologia do estado de S��o Paulo, credenciados pela Sociedade Brasileira de Dermatologia, foram convidados e os 17 que participaram receberam uma planilha de dados e modelos de materiais informativos sobre a doen��a. A campanha foi realizada entre os meses de maio e julho de 2010. Ao t��rmino do per��odo, cada servi��o encaminhou a planilha de dados para an��lise estat��stica. RESULTADOS: Foram examinadas 1718 pessoas e diagnosticados, no total, 90 casos de hansen��ase, a maioria do g��nero masculino e da cor branca, com percentuais semelhantes de multibacilares e de paucibacilares. Doze por cento apresentavam hist��ria familiar de hansen��ase. O maior n��mero de casos detectados foi na capital, seguido, no interior, pela regi��o de Presidente Prudente. O ��ndice de detec����o em menores de 15 anos foi 4%. CONCLUS��ES: Os resultados da campanha mostram a import��ncia desta iniciativa da SBD-RESP. Sugere-se que a����es semelhantes sejam repetidas e que se estendam a outras regionais da Sociedade Brasileira de Dermatologia

Anxiolytic effects of erythrinian alkaloids from Erythrina mulungu

One new erythrinian alkaloid derivative, (+)-11 alpha-hydroxyerythravine (1), and the known (+)-erythravine (2) and (+)-alpha-hydroxyerysotrine (3) were isolated from the flowers of Erythrina mulungu. Their structures were determined by spectroscopic/spectrometric data interpretation of H-1, C-13, and 2D NMR and MS experiments. The relative configuration was established by NOESY analysis, while the conformation adopted by these molecules was evaluated through molecular modeling studies and coupling constants obtained by NMR analysis. Furthermore, the anxiolytic effects of the E. mulungu aqueous alcoholic crude extract and of the purified alkaloids were evaluated using the elevated T-maze test.

Dilatometer tests in a Leda clay crust

The dilatometer test results have been lately applied in foundation design for prediction of settlement and bearing capacity problems. The equipment, its calibration, test procedures and test data interpretation are simple. These advantages seem to explain the increasing use of the dilatometer (DMT) test as a routine technique for subsoil investigation. The DMT test boreholes were carried out on the grounds of the National Research Council (NRC) in Ottawa. Several test results based on laboratory, and other in situ tests available in the literature for the Leda clay deposit in Ottawa area were used to provide correlations between geotechnical properties and soil index parameters as proposed by Marchetti (1980). More appropriated relationships, even though preliminaries, are presented for the crust layer.

Effect of total abdominal hysterectomy on ovarian blood supply in women of reproductive age

Objective. The purpose of this study was to evaluate the effect of total abdominal hysterectomy on ovarian blood supply using transvaginal color Doppler ultrasonography in women of reproductive age. Methods. This prospective study included 61 women aged 40 years or younger who were divided into 2 groups: group 1, comprising 31 patients who underwent total abdominal hysterectomy (TAH), and group 2, comprising 30 women with no abnormalities. Inclusion criteria included normal ovarian function at baseline, with basal follicle-stimulating hormone levels of less than 15 mUI/mL, normal body weight, no tobacco use, and no history of laparotomy or ovarian disease. Ovarian arterial blood supply by determination of the pulsatility index (PI) on Doppler analysis and ovarian volume on transvaginal ultrasonography were assessed at baseline and at 6 and 12 postoperative months. The Student t test, profile analysis, and Friedman and Mann-Whitney tests were used in the statistical analysis of data. Results. Statistical analysis of baseline data revealed that both groups were homogeneous. At months 6 and 12, greater ovarian volumes and lower PI values were observed in patients who underwent TAH (P < .05). By the end of the study, in 8 of the 31 patients who underwent TAH (25.5%), benign ovarian cysts were observed. in the control group, all the parameters studied remained unchanged. Conclusions. The reduced PI values observed on Doppler ultrasonography suggested a decrease in the resistance flow in the ovarian arteries in women of reproductive age who underwent TAH.

Avalia����o da rela����o entre a temperatura da superficie corporal e produ����o de vacas jersey submetidas �� climatiza����o na pr��-ordenha

Jersey cows has been used in warm climates because they have better performance in dairy production. Generally milk production is reduced in warm climates due to the consequent reduction in feed intake because of the heat stress. When the heat stress occurs there is an increase in the body temperature, however it is not known if the skin temperature indicates a thermal discomfort or if it influences milk yield. The objective of this research was to verify if there was a correlation between skin temperature and milk yield using two treatments. Treatment (A) where the cows stayed for 30 minutes before the milking period, in a room with a shower and a fan; and treatment (B) where the cows did not had access to any cooling device (control). After milking the skin temperature were recorded in the places: forehead, back, leg and teats. Data were statistically analyzed and, even though in treatment (A) the skin temperature were reduced it was not found correlation between skin temperature and milk yield.

Determina����o da distribui����o de um n��vel de turbidito na forma����o Maca�� no campo de Namorado atrav��s de uso de atributos s��smicos

This study was developed on the basis of petrophysics characterization, 3D seismic interpretation, and rock-wire-log integration. The results were integrated with amplitude attribute through cross plot (rock attribute x amplitude value). 3D seismic data also allowed inteipreting the top of Lagoa Feia, Maca��, and Carapebus formations, and Outeiro Member. The analyses of the maps of structures and attributes, integrated with wire-log data, suggest that Namorado turbidite level is candidate to be mapped with stratigraphic attributes like AverageTroughAmplitude, RMS velocity and Total AbsoluteAmplitude. Lagoa Feia Formation attribute maps (Dip-Azimuth and TotalEnergy) allows to interpret a low fault density at the carbonate coquina level in the Namorado field. This level is also considered one at the best seismic reflector and an important reservoir of the Campos Basin.
