The aim of this work was evaluate introduction of byproducts of oleaginous in lambs feeding. Diets were composed for 30% of Tifton hay and 70% of concentrate based on corn grain, soybean meal, soybean cake, sunflower cake and peanut cake, limestone and mineral mixture, as dites: FS - control with soybean meal, TS - soybean cake as part of the concentrate, TG sunflower cake as part of the concentrate and TA - peanut cake as part of the concentrate. For performance evaluating 24 Santa Ines lambs with initial age and weight of 70 days and 19 +/- 2 kg, according to a completely randomized design. For digestive evaluate, weight Santa Ines sheep with initial age and weight of 70 days and 16 +/- 1.2 kg, adapted to the use of bag, for collect feces. Animals were distributed in a replicated 4 x 4 Latin Square and means were compared by Tukey's test with 5% significance level. By the performance trial, duration of confinement, weight gain, fed conversion and the dry matter intake were not affected (P>0,05), with averages of 54.29 days, 259 g/day, 4.29 kg of DM/kg and 1.32 kg/day, respectively. There were no difference P>0,05) for intake DM, OM, CP, CT and CE among diets, digestibility trial with averages of 76.23; 74.47; 76.44; 41.12; 73.00 and 93.00%, respectively. There were no differences for digestibility DM, OM, CP, ADF, CT and NCF. The partial substitution of the soybean meal for byproducts of oleaginous was a good proteic alternative in the feeding of lambs.

This study aimed to evaluate the potential for milk production (MP), lactation length (LL) and calving interval (CI), analyze the environmental component affecting these traits, and to estimate the heritability and repeatability for milk production in crossbreds of Murrah buffalo cows in the state of Alagoas, Brazil. Data was composed of 487 observations of MP from 136 lactations recorded between the years of 2000 and 2010. In the analysis of variance for PL, the fixed effects were season (1- October to March, 2 -April to September) and year of the beginning of lactation, calving order and the LL (covariate). For the analysis of LL only the fixed effect of year of the beginning of lactation was included, and finally for the CI analysis, year of the beginning of lactation and calving order. The estimates of covariance were obtained using unicharacteristic analysis by Bayesian inference method, applyingan animal model, through Gibbs sampling. The additive genetic, permanent environment and residual effects were included as random effects in the model. The averages (sd) of MP, LL and CI were 2,218.03 kg (408.18), 282.59 days (39.48) e 422.49 days (91.05), respectively. All the effects included in the models were important (P<0.01). The estimates of heritability and repeatability for PL were 0.29 and 0.69, respectively. The results suggest that there is a moderate genetic variability among individuals for PL, indicating the possibility to obtain gain using selection.

The gene encoding TCTP (Translationally Controlled Tumour Protein) is present in all eukaryotes and its product is involved in various cellular processes. Although well characterized in mammals, there are only few works available in the literature related to the analysis of this protein in plants. In this present work, the expression of the gene encoding TCTP was analyzed in different organs/tissues of tomato plants (Solanum lycopersicum cv. Santa Clara). A quantification performed by RT-qPCR revealed the presence of TCTP transcript in all tissues/organs analyzed, with the highest expression level found in leaves. With the exception of fruits in intermediate stage of maturation, for which a small increase on the expression was detected, there was minimal variation in the relative expression of TCTP in other organ/tissues. In parallel, the effects of the constitutive expression of TCTP were investigated using transgenic tobacco lines able to overexpress this protein at different levels (T1, T2 and T3). Seedlings of these lines, and of a non-transgenic control line, were grown in MS culture medium for 21 days. At the end of this period, the length of roots and leaves was taken and the seedlings were photographed. According to Tukey's test, the analysis of the mean root length revealed a significant difference between T1 and T3 lines when compared to the control, although the same was not observed for the T2 line. For leaves, according to Kruskal-Wallis test, there was a statistical difference between the averages of leaf growth obtained for the different lines evaluated. According to these results, we can conclude that TCTP shows an ubiquitous expression in tomato plants, with the highest expression detected in leaves, and also that its overexpression promoted a higher root and leaf development in two of three transgenic tobacco lines tested

The work is guided by the detailing of the Itajaí river basin, SC, rainfall dynamics at the annual, seasonal and monthly levels, allowing us to identify different responses that each location gives to the regional atmospheric circulation, particularly the rainfall. In this sense, we are aiming at approaching the concept of rhythm, which must be obtained at the daily level. The analysis at different climate scales was possible through isohyetal maps, trend lines, and Schroeder pluviographs. Moreover, we established the flow rate of the air masses by means of the Venn diagram. This data made it possible to assess the behavior of rains on that site and the reason why it is the stage of major flooding, as occurred in November 2008. The relatively mountainous topography combined with the frequent invasions of the Atlantic Polar Front, which often stop over the region, generate events of that magnitude, with high volumes accumulated in short periods of time. Such extreme events reinforce the idea of the search for the succession of types of weather to the detriment of averages that tend to abstract the reality

This project aims the verification of doses in canines and felines to chest and coxal exams due to the transition from screen-film to computed radiography system. It also seeks a possible optimization of the new techniques employed in this new system. The study was carried out in Diagnostic Imaging service in Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da Universidade de São Paulo using a conventional x-ray equipment. Initially, data about the physical characteristics of animals and the technique currently used in computed radiography was collected for each of 80 chest and 16 coxal X-ray examinations. The animals were divided into different groups according to the body weight. For each group, were calculated the averages of each item: thickness of the region to be imaged, voltage, current, exposure time, current-time product, size of film used, presence or absence of bucky and focus (small or large). The techniques have been reproduced in phantoms (representative of the thickness of the animal) in order to collect the air kerma entrance. Based on the average of intermediate size M group (weights less than 5 kg for cats and from 10.1 kg and 20 kg for dogs) analysis of image quality using three devices test patterns were made consisting of the evaluation of spatial resolution, low-contrast resolution and contrast-detail. In general, the results showed the dose animals decreased with the use of computed radiography and was possible to preliminary optimization of some techniques used currently in CR

This work presents procedures for getting data to estimate grant flow by means of statistical and hydrological methods, acquired during the graduate course, of some streams in the watersheds of Aguapeí and Peixe rivers, in order to make available this data set to Sao Paulo State water and electrical energy department – DAEE and to the Committees of Aguapeí and Peixe watersheds. This study was performed using discharge data and the were a selection process to identify some faults in the historical series. Finally it was calculated the 7-day moving averages, Q7 and some characteristics discharges like Q90 and Q95. Taking into account the average discharge en seven days in a 10-year recurrence interval, it was estimated the grant flow of some streams. Data were generated for six posts inside the Aguapei and Peixe watersheds
