The present study aimed to survey the medium and large land mammals in three fragments at the Fazenda Experimental Lageado - UNESP/Botucatu, through the method of sand plots. 48 plots were used in total, 16 on each track. The paw prints found were photographed and identified from specific guides. 12 different species of mammals were found, these, 7 were classified at the level of species belonging to 9 families and 6 orders. The most representative order was Carnivora. Most of the species found have a generalist or omnivore habit, which can be related with the degree of the forest fragmentation. The only fragment of natural forest (semideciduous), presented the fewer numbers of species, which can be explained due to its isolation. The other fragment, which has near highway and other large fragment (Fazenda Experimental Edgárdia) was the most representative fragment, demonstrating the importance of nearest fragments to the continuity and survival of medium and large mammals

In this work, we intend to show that Aloysius Bertrand in “Gaspard de la Nuit” drew the inspiration to his poems in prose from its nearest context: that one of French Revolution and the revolt of the spirit against everything which would impose an exaggerated materialism. Thus, in the middle of Enlightenment, there were those who went in search of “mysterious realities” and a “sense of mystery” that the pre-romantic literature in Britain and in Germany would express in its poetry. It is also in the 18th century that some works about the “Commedia dell‟arte” and caricature concede to the grotesque a significant part in the formation of art, extending it to the supernatural and the absurd.

Phase transitions involving spontaneous time-reversal symmetry breaking are studied on the honeycomb lattice at finite hole doping with next-nearest-neighbor repulsion. We derive an exact expression for the mean-field equation of state in closed form, valid at temperatures much less than the Fermi energy. Contrary to standard expectations, we find that thermally induced intraband particle-hole excitations can create and stabilize a uniform metallic phase with broken time-reversal symmetry as the temperature is raised in a region where the ground state is a trivial metal.

The impact of peritoneal dialysis modality on patient survival and peritonitis rates is not fully understood, and no large-scale randomized clinical trial (RCT) is available. In the absence of a RCT, the use of an advanced matching procedure to reduce selection bias in large cohort studies may be the best approach. The aim of this study is to compare automated peritoneal dialysis (APD) and continuous ambulatory peritoneal dialysis (CAPD) according to peritonitis risk, technique failure and patient survival in a large nation-wide PD cohort. This is a prospective cohort study that included all incident PD patients with at least 90 days of PD recruited in the BRAZPD study. All patients who were treated exclusively with either APD or CAPD were matched for 15 different covariates using a propensity score calculated with the nearest neighbor method. Clinical outcomes analyzed were overall mortality, technique failure and time to first peritonitis. For all analysis we also adjusted the curves for the presence of competing risks with the Fine and Gray analysis. After the matching procedure, 2,890 patients were included in the analysis (1,445 in each group). Baseline characteristics were similar for all covariates including: age, diabetes, BMI, Center-experience, coronary artery disease, cancer, literacy, hypertension, race, previous HD, gender, pre-dialysis care, family income, peripheral artery disease and year of starting PD. Mortality rate was higher in CAPD patients (SHR1.44 CI95%1.21-1.71) compared to APD, but no difference was observed for technique failure (SHR0.83 CI95%0.69-1.02) nor for time till the first peritonitis episode (SHR0.96 CI95%0.93-1.11). In the first large PD cohort study with groups balanced for several covariates using propensity score matching, PD modality was not associated with differences in neither time to first peritonitis nor in technique failure. Nevertheless, patient survival was significantly better in APD patients.

A complete morphological description, supported by molecular data, of Clinostomum detruncatum metacercariae is reported in this study. The metacercariae were found infecting Synbranchus marmoratus from the Paraná River, municipality of GuaÃ-ra, Paraná State, Brazil. The taenioidean uterus is the main morphological characteristic of this species. Both Neighbour-Joining (NJ) and Maximum Likelihood (ML) trees showed 2 clear separate clusters grouping together the species from the Palearctic region (Clinostomum complanatum, Clinostomum cutaneum, Clinostomum phalacrocoracis, Clinostomum philippinense) and from the Nearctic/Neotropical regions (Clinostomum marginatum, Clinostomum tataxumui, C. detruncatum, Clinostomum sp. 7). The latter clade is divided into 2 subclades grouping species from North America and Mexico (C. marginatum and C. tataxumui), and from Brazil (C. detruncatum and Clinostomum sp. 7).

This paper relates some considerations resulting from a thesis study in Biological Sciences held at Universidade Estadual Paulista - Unesp, Bauru Campus. Considering the perceptual act endowed with simultaneous actions of the cognitive apparatus and the individual's life history as the merleau-pontyana phenmomenon tells us, the work aimed to identify how boys and girls in elementary school realize a natural savanna. The study was realized with the extension project "Walking and learning at the cerrado” in the Center for Memory and Dissemination of Science and Technology (CDMCT) of Postgraduate Education for Science in the same institution. Classes were held in these practical activities, monitored by undergraduate and graduate students, and, the project focuses on students from public and private schools in Bauru and region, and other visiting groups. Data collection was performed using the representations in the form of free drawings of students of their environment after the activity. Through qualitative and quantitative analysis, the results allowed us to highlight differences in the way in which genders perceived and thus represented the fragment of cerrado vegetation. The male drawings contained a larger amount of non-living elements, whereas the representations by women, besides their botanical details, often drew on animals and people. The framework of the drawings by the boys took the nearest way, whereas by the girls more often considered the representations and the entire context of the site visited. So, we emphasize the need for further discussions within the perception of the environment to consider differences in the representations of boys and girls within the context of the teaching of natural sciences, seeking, however, to avoid unsubstantiated preconceptions that may cause any degree of discrimination.
