Avaliação convencional e estesiômetro: resultados controversos na avaliação sensitiva no câncer de mama

This study, clinical, prospective, randomized study was conducted from August 2004 to February 2008 in a convenience sample of 60 women who underwent breast surgery with axillary dissection, divided into two groups (n = 30). The GI (Guidance Kit with different textures, to perform at home) and GII (control). The objective was to analyze the effect of home orientation in patients after surgery for breast cancer complaining of numbness, evaluation, and the conventional esthesiometer. The surface sensitivity was assessed by monofilament Semmes-Weinstein and evaluation using conventional two test tubes with hot water (38 to 43o C) and cold (16 to 27o C), paintbrush, needle. The GI was subjected to 10 sessions and assessments in both 3 times. The M1 (pre intervention), the M2 (post-intervention) after 10 sessions of physical therapy intervention and M3 (washout) after 3 months the second time for assessment. The region targeted for evaluation and intervention was the sensory nerve dermatome intercostobrachial. In the test of Goodman (conventional assessment) there was improvement in both groups, the P1, during the thermal evaluation. The t-test of student (esthesiometer) there was improvement in P2 only in GI (p = 0.003) between points 1 and 2 while the time 3 (p = 0.121 and p = 0.733 respectively). It was concluded that there were divergent and opposite results after examining the effect of home orientation in the nerve dermatome intercostobrachial, evaluation, and the conventional esthesiometer.

Criopreservación de semen bovino de la cola del epididimo utilizando los métodos convencional y automatizado

Cryopreservation of sperm is important to preserve the germplasm from animals of genetic value, which can die unexpectedly. This study compares conventional and automated methods of cryopreservation of spermatozoa obtained from the epididymis of bulls post-mortem. Twenty-two epididymides were obtained from a commercial slaughterhouse. Spermatozoa were collected from the tail of the epididymis using the retrograde flow technique. Thus, the samples, which were diluted in 10 ml of extender without glycerol (Botubov® I, Botupharma, Botucatu, SP, Brazil), were evaluated on motility, sperm vigor, structural and functional (swelling hypoosmotic test) membrane integrity, mitochondrial activity, sperm viability and ADN fragmentation. The samples were divided into two aliquots and diluted in extender with glycerol (Botubov® II, Botupharma, Botucatu, SP, Brazil) at a concentration of 50x106 motile sperm/0.5 French straws. One sample was frozen by the conventional method (4 hours at 5°C, in a refrigerator and 20 min in nitrogen vapor) and the other by the automated method (Cryogen® Dualflex, Neovet, Uberaba, MG, Brazil). The parameters were higher in all the tests of fresh sperm samples, with the exception of the swelling hypoosmotic test, which showed no significant difference when the results were compared with sperm frozen by the conventional method. The average motility of fresh spermatozoa was 74%, and conventional and automated averages were 29 and 25%, respectively. Therefore, although cryopreservation techniques reduce sperm quality parameters, the viability of the sperm is maintained, and these methods can be used to preserve sperm.

Rentabilidade e Risco da Produção de Milho Safrinha Geneticamente Modificado e Convencional na Região de Guaíra/sp

The objective of this study was to dimension the economic risks and returns on adopters of genetically modified (GM) maize in one of the major corn producing regions of São Paulo state. We performed analysis of variation of the quantities and prices of insecticides used, productivity gains, and variation in the price differentials between GM maize and conventional hybrids seeds, according to account to the maize prices oscillation during the period studied. The net benefits methodology was used, in other words, the economic gains minus the costs of GM technology under risk conditions were calculated. The net benefits was calculated as a function of four critical variables: 1) GM maize productivity; 2) costs of pest control; 3) maize price; 4) GM seeds cost. The probability distribution functions of these critical variables were estimated and included in the net benefit equation. Using the Monte Carlo simulation methodology, the following indicator sets were estimated: central tendency measurements, variability in net benefits (total benefits minus total costs), sensitivity analysis of the net benefits in relation to the critical variables, and finally, a map of the risk to GM technology adopters. These indicators allow one to design economic scenarios associated with their probability of occurring. The results showed probability of 85% to positive gains to the farmers who adopted the transgenic maize seed cultivation. The variable with the greatest impact on the farmers' income was the reduction in productivity loss, that means, as higher is the maize productivity, higher will be the net income. The average gain was US$ 137,41 (R$ 2.45/US$)per hectare with the adoption of transgenic maize seed when compared to conventional maize seed.

Levantamento planimétrico de pequenas propriedades rurais pelo sistema convencional e pelo receptor (gps) de navegação

The present study aimed to compare the planimetric survey data of an area equivalent to a small rural property, through values of longitudes e latitudes obtained by a GPS navigation with a conventional survey data. The value of the area obtained with the navigation receiver showed a small difference when compared with the conventional system. Points located under large vegetal cover had impaired reading of coordinates. The navigation receiver can be used to get measurements inside the property for planning purposes and also for measuring he land perimeter, but not for legal purposes. The Google planimeter result in the same area as the one from the conventional survey data.

Pesquisa, projeto e construção de um sistema de ignição sem distribuidor

This work intends to know the most types of ignition systems, studying its history, the way it works, applications and some examples. The assembly of a distributor less ignition system is also required. All vehicles powered by internal combustion engines need an ignition system that allows this engine to ignite the air-fuel mixture using its ignition system in the best possible manner. The main goal of an ignition system is to obtain a spark having enough energy to start the chemical reaction of the oxygen and the fuel. It took a study dealing with the various types of ignition systems since their creation at the beginning of the last century until 2015. The work starts studying the high tension magneto ignition system and later together with the low tension ignition system, going on with the conventional ignition system and finally accomplishing with the various types of electronic ignition systems. It was studied and implemented an electronic circuit to power a double spark ignition system also known as wasted spark ignition system. This circuit was assembled with an electric pulse generator and powered mechanically by a dc electric motor of the variable rpm type

Avaliação ecocardiográfica do átrio esquerdo de cães sadios por meio do modo-M convencional e do modo bidimensional

Avaliaram-se o átrio esquerdo (AE) utilizando-se o método bidimensional (2-B) (corte transverso) e a relação átrio esquerdo:aorta (AE:Ao), em um grupo de 40 cães adultos e sadios, entre um, cinco e sete anos de idade e com pesos corpóreos de 3,2kg a 38,3kg, e compararam-se esses valores aos do modo-M convencional. Observou-se diferença entre AE e Ao nos dois métodos e entre os seus respectivos índices. A correlação foi positiva alta entre peso e superfície corpórea e entre AE no modo 2-B (AEB) e AE no modo-M (AEM). Não se observou correlação entre os índices, nos dois métodos, com o peso e a superfície corpórea, isto é, os índices são independentes do peso ou da superfície corpórea. Concluiu-se que o AEB é maior do que o AEM, o índice médio para o AEB:AoB é de 1,379, e o intervalo de confiança de 1,337 a 1,422. O índice no método 2-B é, portanto, superior ao índice no modo-M.
