This paper has as an objetive to present the survey outcomes on the railroad heritage listed by CONDEPHAAT (identification, state of conservation and public politics of use). In one hand, since the 1960s has been formulated the concept of industrial heritage, it would consider the relevance of this concept for the railroad heritage. In the other hand, it is also necessary to understand the concepts that have guided the tipping process of this organ for decades. Anyway, this is to assess the extent to these new concepts of heritage has guided the actions of the São Paulo State Council

This paper is the result of a homonymous scientific research, funded by CNPq-PIBIC where we understand the adoption process as a process of dissidence in relation to the bio-parental matrix. Founded on a heteronormative naturalization of human sexuality - which presupposes a continuum and naturalized organization among sex / gender / desire – this bioparental matrix sets the binary relation of distinction between the legitimate/illegitimate child as their origin or not arising from “blood ties”. Considering our experience in the Project developed at the Department of Clinical Psychology at UNESP, Assis, SP called “Ties of love: Adoption, Gender, Citizenship and Rights”, we prepared a content analysis - as proposed by Bardin (1977) -, of transcripts of psychological sessions that were made from 2005 to 2012 in the "Center for Research and Applied Psychology “Dra. Betti Katzenstein. Our general objective was to analyze the effects of the bioparental matrix and its impact on children/adolescents and their families as well as estimate the possibilities of escape to the subjection to this bioparental matrix. The results showed us several aspects that may be significant for understanding the discursive crossings related to the practice of adoption. It was observed that there is still a great ambivalence pervading this theme, revealing that there is a discrepancy between what we say and what we do in relation to practices of caring among the adopted children. On the one hand, it was noticed that relatives rationally seek to enhance the bonding of the “emotional ties”, but their practices and beliefs, are still supported in modes of subjectivation that prioritize the biological discourse. This fact reveals a strained and conflictive field that probably weaknesses those families seeking to prioritize the ties of affection. However, as can be seen in this study, it is comforting and motivating to realize the power of resistance of individuals to absolute truths that govern their ways of feeling, affiliating and/ or exert their parenting.

Two experiments with 25 maize commercial hybrids were carried out in a direct sowing system in Southern Brazil in the harvests of 2009/2010 and 2010/2011. Quantitative descriptors were used with the objective of determining the genetic divergence and the relative contributions of traits among hybrids for extraction of inbred lines. This study was carried out in Oxisol soil using a randomized block design with four replicates. Data were subjected to combined analysis of variance, and based on the multivariate analyses, Tocher and average linkage (UPGMA) cluster analyses, based on generalized distance of Mahalanobis, to quantify divergence in addition to Singh criterion to validate trait with the most contribution. The multivariate methods were consistent with each other, and the weight of 100 grains was the trait that contributed most to the divergence and had similar behavior in grain yield between hybrids in both years. Furthermore, this descriptor representing significant genetic variability for crossings and lines extraction to hybridization between BM 3061, ATL 200 and P 30B39 Y.

Context. The giant anteater, Myrmecophaga tridactyla, is a large insectivorous mammal from Cerrado which is classified as vulnerable by the IUCN's red list. In spite of frequent giant anteater casualties, there continues to be a lack of published data on how road and landscape attributes affect road-kill rates - information that could prove useful in guiding mitigation measures.Aims. We seek to determine whether road and landscape attributes influence the incidence of road-kills of the giant anteater.Methods. From February 2002 to December 2012 (except for 2004), five roads in two regions in south-eastern Brazil were surveyed twice each month by car. We recorded temporal road-kill data for the giant anteater and related spatial road variables. These variables were also recorded at regular control sites every 2 km. We also took traffic volume data on stretches of the two roads to correlate with road-kills.Key results. Of the 45 anteater casualties recorded, there was a predominance of adult males. On roads MG-428 and SP-334, we found anteater road-kills were more common in the dry season, negatively correlated with traffic volume and related to the presence of native vegetation. Accordingly, road-kill sites tended to occur near the cerrado and grasslands and also appeared more frequently on some straight stretches of roadways. Although it was not shown to influence road-kill rates, topography data does point to regular overpass/underpass locations allowing population connectivity. Termitaria or ant nests were present at all road-kill sites, with 86% having signs of feeding.Conclusions. Native vegetation along roadways, together with straight road design, increases the probability of anteater road-kills by 40.1%.Implications. For mitigation, mowing and removing insect nests on roadsides, as well as roadside wildlife fencing in cerrado and grassland areas is suggested. Warning signs and radar to reduce vehicle speed are recommended for both human safety and anteater conservation. With regard to population connectivity, the absence of aggregated anteater road-kill data in this study meant that there were no particular crossing locations identified. However, the collected topography data do show places that could be used for roadway crossings. The measures indicated may apply to similar species and types of topography on other continents.

This scientific research aimed at to analyse the susceptibility to debris flow of the watershed of Ribeirão do Roque (SP), focusing on the upstream areas of OSBRA pipeline. This is because, mass flow can cause damage to pipes, mainly due to conditioning hydro erosion of the land in the drainage crossings, including the undermining the banks of streams. Firstly, It was conducted a literature review, aiming to identify and understand the principal characteristics and conditions of debris flow. Secondly, the physical and anthropic factors and their respective weights of influence were selected and used to determine the mass flow susceptibility. It was selected the following physical factors: type and thickness of rocks, soil and unconsolidated materials; textural density; amplitude relief; relief slope; shaped valley; and shape of slopes. Such factors are present in the physiographic subdivision map of the study area. In addition, the anthropic attributes correspond to the classes contained in the land use map. Therefore, the physical and anthropic factors were integrated through the multi-criteria analysis in a GIS environment, generating a total susceptibility map of debris flow on the scale 1:50,000. The results showed that a significative part of the study area was classified as average susceptibility. However, it was identified areas with high susceptibility in the region in which the pipe cross the Ribeirão do Roque. Moreover, at which point the river presents a closed valley and a meander shape, without a fluvial plain that would be useful to attenuate the development of the process. Consequently, if a mass flow begins in any of these most susceptible regions located upstream of the pipe, the chances that the process develops by the river and causes the excavations of his bed are quite large. However, the pipelines cross these critical areas directly on the rock (diabase), which provides additional protection against possible ...

Three newborn Mini-Horses and one Brazilian Pony horses were presented to the Veterinary Hospital with phenotypic appearance of dwarfism. They had relatively larger head conformation, occlusive dental defect and musculoskeletal changes such as abnormal short limbs and deformation on the third metatarsal bone. The radiographic examination showed abnormal growth plates on femoral condyle and proximal thirds metatarsal bones. Due to the high possibility of future complications and quality of life loss, the animals were euthanized. We emphasize the importance of recognition of phenotypic changes related to dwarfism in horses, enabling the phenotypic diagnosis can direct crossings for nontransmission of this abnormality as genetic inheritance.
