Eccos Revista Científica , 2008,
Abstract: This paper presents some of the results of the implementation of a Teacher Development Program as undergraduate course at distance from Curitiba to poles spread out in the country.. To get a unit all through the course, teachers, as authors, write textbooks and virtual teaching material in a dialogical instruction mode to guide students in their lonely study. They have their students to interactto each other, independently of their genre, age, sex, ethnic from the activities they assign in those texts. When they teach in front of a camera in a studio, the interact via phone 0800; as tutors, they speak in the Web Radio and they participate in chats; as local tutors, teachers interact and motivate students in their poles. Both when they teach in the studio and reach students by satellite and in the tutorship when they talk to students by phone, or via Internet, they foster them to work in teams and develop collaborative work and attitudes.

Abstract: The milk is an important food because it contents Conjugated Linoleic Acids (CLA). These fatty acids are synthesized in mammary gland under action of the enzyme Stearoyl CoA-Desaturase (SCD) and have showed some positive effects in human disease prevention and treatments. A variation of CLA in milk fat exists and can be partially explained by the different levels of expression of SCD. The aim was to study part of the encoding regions of SCD′s gene using PCR-RFLP (Polymerase Chain Reaction-Restriction Fragment Length Polymorphism). Genomic DNA was extracted from lactating Murrah females. After this, PCR reactions were made by using primers Z43D1 that encloses exon I, II and intron I. The fragments amplified are composed by 938 pb. Then, RFLP techniques were applied in the fragments using the restriction enzymes Pst I and Sma I. The enzyme Pst I has generated fragments of 788pb and 150bp and the Sma I has generated fragments of 693pb and 245pb. All the animals showed the same migration standard for both enzymes, characterizing a genetic monomorphism for this region of SCD gene. The analysis determined that there aren’t genetic differences between these animals in the studied regions by using Pst I and Sma I enzymes.

Abstract: considering that species of rodents have different means of locomotion, this study presents and discusses variations on the anterior and posterior footprints shape of seven species [akodon cursor (winge, 1887), necromys lasiurus (lund, 1840), oecomys bicolor (tomes, 1860), oecomys concolor (wagner, 1845), oligoryzomys nigripes (olfers, 1818), hylaeamys megacephalus (fischer, 1814) and rhipidomys macrurus (gervais, 1855)], using geometric morphometrics and discriminant analyses. shape variables were related to phylogenetic topology and means of locomotion of the species to verify the influence of historical or ecological factors on footprints morphology. footprints shape of the arboreal rodents (short and wide) was clearly distinct of cursorial ones (narrow and elongated). the anterior (kappa = 0,72) and posterior (kappa = 0,88) footprint reclassification was considered substantial and almost perfect, respectively. the posterior footprints presented better results of species discrimination and set the levels of arboreal and cursorial activity of rodents. allometric effects were observed in anterior (13%) and posterior (3%) footprint analysis. the means of locomotion explained 90.3% of footprint rodents shape variation (p = 0.02), indicating convergence on footprint morphological patterns of arboreal and cursorial rodents.

Abstract: theoretical models of gouy-chapman and stern, referred to diffuse double layer, were applied to three acric oxisols, two named dusky red latosol and one una variant latosol, from the s?o paulo state - brazil. samples were collected in ribeir?o preto and guaira, regions of large occurrence of these soils, supporting many economic crops. in the highest concentration of the electrolyte (kc1 0.1n), the obtained values were better related to the stern model. on the other hand, in more dilluted solutions (kc1 0.01 and 0.001n), corresponding to more usual ionic strenght of highly weathered soils, the variation of surface charge density of the samples with electric potential was in better agreement with the gouy-chapman theory.

Abstract: physical attributes, i.e, water dispersible clay (wdc), available water (aw) and specific surface area (ssa) of surface and subsurface samples of three acne oxisols from the s?o paulo state - brazil (two dusky red and one una variant latosol) were studied. wdc decreased markedly with depth and their values were 0 and 2% for the b horizon. in that layer, electric charge density, surface potential and dph were close to zero, promoting colloid flocullation. amounts of aw were low (<6%) in all samples, with exception of the surface layer from one of the dusky red latosols, for which available water was medium (6-12%). those low values reflected strong microagreggationof the acric oxisols, whose water retention and movement are similar to sandy soils. ssa had small values, varying from 42 to 104nrvg, as a result of a predominance of kaolinite and oxides in the soil clay fraction. a positive correlation was obtained between ssa and the amounts of organic carbon and iron oxides.

Italian Journal of Animal Science , 2010, DOI: 10.4081/ijas.2010.e34
Abstract: New statistical models for genetic parameters estimation based on longitudinal data have being proposed. In this study, information of 47,614 test day milk yield data from 1.578 buffaloes, with 4.757 complete lactation, which calves from 1985 to 2006, were considered. Single-, two- and multiple trait analyses were used and variance components were estimated by Restricted Maximum Likelihood. The model used to evaluate the milk yield at 305 days (MY305) trait included herd-year-calving season (contemporary group) and milking number as fixed effects, buffalo age at calving was considered as covariate (linear and quadratic effect) and additive genetic, permanent environmental, residual and the animal were considered random effects. The same effects were included in the test day milk yield model except the contemporary group defined as herd-year-test day month control. The heritability estimations for TDMY vary from 0.13 to 0.23 for single-trait analyses, from 0.13 to 0.24 for two-trait analyses and from 0.15 at 0.24 for the multiple-trait analyses. According to the three models analyzed, the higher heritability estimations were obtained in the third test month for all of them. The genetic correlations between the TDMY and MY305 were high and positive. In conclusion, the selection for TDMY trait will promote genetic changes to the same direction for MY305.
