Caracterização da distribuição física dos dolomitos do membro Búzios no Campo de Badejo - Bacia de Campos

In the region of Badejo oil Ffeld (Campos Basin) lies an Lower Albian dolomitic layer that shows reservoir rock and seal conditions, among others and, it is occasionally karstified. This work applies geostatistical techniques of ordinary and indicatior kriging, in an attempt to determine a method that assists the analysis of different scenarios offered for petroleum drilling from a quantitative point of view this fact is justified, because there are different visions and strategies that would be adopted under different dolomite conditions (stable - low porosity and high density; reservoir - high porosity and medium density; instable - high porosity and low dentisty). The main objective is a methodological introduction that has not been tested in dolomites before aiming to characterize the distribution of the three conditions described above by ordinary and indicatior kriging, which was based on the obtained data from the dolomite layer identification through well logs interpretation and correlation, followed by seismic interpretation. In addition, it was generated structural contour maps, based on 2D and 3D seismic data interpretation, and then, seismic attributes maps were calculated, in order to transform them into pseudo-density maps, i.e., maps that correlate the density values with the attribute values. As primary results, structural contour maps and seismic attributes were obtained and ordinary and indicatior kriging maps were done, on which it is possible to interpret the distribution of the main reservoir and risk probability for drilling of exploration wells obtaining trends N35E and N10W direction for areas of stability or reservoir levels, while the central part of the map presents a higher risk for loss of drilling fluid. The cut-off values levels were based on the values of first and third quartiles of cumulative histogram (instable and stable zones, respectively), as well as the reservoir level was set as the interval...

Degradabilidade de grãos secos e ensilados de sorgo com e sem tanino, submetidos à granulometrias

Due to its nutritional characteristics sorghum has been indicated as substitute cereal to corn and wheat. Besides, in Brazil sorghum is not used for human feeding unlike corn, witch reduces its costs in almost 20% in comparison to corn costs. This research was conducted at UNESP, in Botucatu and Jaboticabal Campus, São Paulo, Brazil, with the purpose to evaluate the grinding effect on two sorghum genotypes grain (with and without tannin) preserved dry or ensiled humid above the degradability in situ of the dry matter, crude protein and starch. Three rumen fistulated sheep were used, distributed in an experimental block design, at 2 x 2 x 3 factorial outline, with two sorghum genotypes (with and without tannin), two forms of conservation (dry grain and high moisture grains silage) and three grinding ways (undivided, thick grinding and fine grinding) and the time as sub-portion. According to the results the grinding is recommended to sorghum grains because it increases the ruminal and effective degradability of the dry matter, crude protein and starch. The presence of tannin in sorghum grain changed the degrability potential of crude protein and starch. The thick grinding in dry grain without tannin was the better treatment.

Degradabilidade da matéria seca e da proteína bruta de grãos secos e de silagens de grãos úmidos de híbridos de milho (Zea mays), submetidos a diferentes processamentos

The objective of this work was to evaluate the effect of processing two corn hybrids conserved, dry and humid grains, the dry matter (DM) and crude protein (CP) degradability in situ. The particle size was determined and difference was verified in MGD (Medium Geometric Diameter) of processed ingredients. Three sheep were used with rumen canulated, in a completely randomized design, using a factorial outline 2 x 2 x 3, being two corn hybrid, two conservation methods and three processing forms (whole, coarsely and finely ground), with five times of incubation (3, 6, 12, 24 and 48 hours). The fraction A in SDC (silage of dent corn) of DM was superior to GDC (grain of dent corn) in all of the particles size. The ensiling process increased the DM solubility, reducing the fraction B in comparison to dry grain. The values regarding the fractions DP and DE the 5% per hour of the protein, were larger for SDC and GDC, it presents a decreasing when the incubation time advances. The fermentation rate was superior for SDC and GDC. The ensiling process has positive effect in the decreasing of DM and CP in comparison to GDC.

Histerocele inguinal em cadela com piometra: relato de caso

A histerocele inguinal e uma hérnia pouco frequente, caracterizada pela protrusão do útero pelo canal inguinal, ocasionando sinais clínicos em decorrência de gestação ou alterações uterinas, dentre elas a piometra, tendo como causa primaria o desequilíbrio hormonal levando ao enfraquecimento de tecido conjuntivo, que distende os anéis inguinais. Pode ser causada por um conjunto de fatores tais como obesidade e aumento da pressão intra-abdominal, acompanhada pelo enfraquecimento das estruturas de contorno adjacentes. Foi relatada a ocorrência de histerocele inguinal com piometra em uma cadela da raça Poodle, com nove anos de idade, atendida no Ambulatório de Reprodução de Pequenos Animais do Hospital Veterinário da Universidade Paulista “Júlio de Mesquita Filho” Unesp – Botucatu – SP. As alterações clínicas observadas foram presença de secreção vulvar mucopurulenta, hipertermia (40,2°C), vasos episclerais ingurgitados, apatia e anorexia, além da presença de hérnia inguinal esquerda. Ao exame ultrassonográfico da cavidade abdominal e da hérnia, constataram-se áreas lobuladas com regiões anecoicas bem evidentes, características dos achados ultrassonográficos de piometra, tanto no interior da cavidade como no conteúdo herniário. Os achados hematológicos revelaram anemia normocítica e normocrômica, leucocitose grave, neutrofilia e desvio a esquerda; o exame bioquímico do soro revelou alteração das enzimas hepáticas, hiperglobulinemia e hiperproteinemia, condizentes com o quadro de piometra. Diante do quadro clinico, procedeu-se laparotomia de caráter emergencial e verificou-se que ambos os cornos estavam repletos de secreção e que o conteúdo herniario tratava-se do corno uterino esquerdo. O corno distendido foi removido do anel inguinal lentamente e, apos a ovariosalpingohisterectomia (OSH), foi realizado a redução do anel inguinal esquerdo. Apos a recuperação pós-operatória, restabeleceu-se a saúde do paciente.

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.

Perda de matéria seca em grãos de milho submetidos a sistemas de secagem natural e artificial.

The permanence of the corn grain in the field, after physiological maturity, is an important cause of crop losses, both in quantitative and qualitative aspect. By ceasing the supply of assimilated substances to grains, due to physiological maturity, the synthesis reactions are overcome by breathing, responsible for the maintenance of the living tissues of the grains, which occur at the expense of reserves accumulated during grain formation. In addition, there are losses from fungus and insects attack due to adverse weather conditions. Technological advances in recent decades, the develop of grain dryers with different capacities and efficiencies, has led to the early withdrawal of the product from the field, still damp, reducing spoilage. Moreover, the use of artificial drying systems can represent a significant cost to the producer. Thus, the present work aimed to study the effect of natural and artificial methods of drying on maize dry matter losses, for Botucatu, city of Sao Paulo state, Brazil. The cornfield production was conducted at the Experimental Farm “Lageado” and the experimental treatments were conducted in the Laboratory of Agricultural Products Processing, in the Department of Rural Engineering, where the drying systems were tested. The treatments were: shade (control), artificial with heated air, artificial unheated air and, drying attached to the plant. The following analyzes for quality monitoring were performed: weight test, thousand-grain weight test and, grain dry weight. The results showed significant loss in quality of drying beans attached to the plant, by assessing the dry matter loss and by the variation of the grain weight. The weight test showed that the worst performance was the artificial with heated air treatment. We used mathematical modeling techniques to describe the dry matter loss and adjusted the mathematical model to the experimental data analyzed. From the experimental data obtained during drying the grain attached to the plant, it was still possible to fit a regression model that estimates the loss of grain dry matter under the climate from Botucatu during the 2011/2012 harvest period.
