Dinâmica da vegetação de uma floresta paludosa no município de Rio Claro - SP

Swamp forests, are laid down in the lowlands, with almost permanent presence of water on the soil surface and generally occupy portions fairly flat. In 2003 a phytosociological survey was conducted of the tree and shrub component of a swamp forest established on a steep slope in Rio Claro - SP, through the use of 45 permanent plots of 10 mx 10 m (0.45 ha) divided into three blocks: 1, 2 and 3. The present study aimed to review these plots and discuss the dynamics of vegetation in the swamp forest in question period of eight years. Altogether 1529 individuals were found alive, belonging to 29 families and 47 species. It can be observed that there was a decrease of one family (Flacourtiaceae) and two species (Xylosma tweediana, Inga marginata) in relation to 2003. In general there was a loss not only in number of individuals, but basal area and species diversity. The Block 1 was the only one to show a positive balance in terms of numbers of individuals (2.75%); in Block 2, there was little variation (1.72%) which is negative; whereas Block 3 had the largest decrease, 19.18%. The mortality rate (2.74% / year) for the community remained higher than the recruitment (1.81% / year). There was a decrease (3.19%) of total basal area of the sample relative to 2003, with the highest relative dominance by Calophyllum brasiliense. The decline in diversity of species could be evidenced by the Shannon index, which was 2.0 nats.individual-1 and evenness of 0.52. The most important species (IVI) were Euterpe edulis, Calophyllum brasiliense and Magnolia ovata, together accounting for 59% of IVI community. High mortality and low recruitment rates indicate disturbances in the community, some factors such as proximity to roads, the different soil types associated with a high rate of water saturation and the declivity are crucial to the balance within the community

Eficiência energética em ar condicionado e refrigeração através da aplicação da termoacumulação

The use of refrigeration and air conditioning systems is of fundamental importance when it comes to air-conditioning of environments. Also important is the use of electricity for equipments’ operation related to these systems. Due to high cost of charging for this type of energy, factors economy and efficiency occupy key roles among design parameters of a system. One of the ways to get this economy is the use of a technique called thermal storage, or cold storage, which intends to move the required loads during peak time and also their equalizing, so that the energy is transferred from the peak time to non-peak time, thereby reducing the cost of energy consumed. Cold can be stored in the form of ice or ice water. This work aims to perform a technical-economic analysis of a mall located in Vale do Paraíba checking the feasibility of deploying a thermal storage system to achieve an economy in the cost of the energy used by the establishment. Through the parameters measured by the concessionaire of energy we can get the values of energy demand and power consumed, which will serve as basis for calculation for the study. The results obtained allow the development of two alternative proposals to the current configuration, one chosen by the criteria and results presented by technical-economic and energy analysis

Comunidade de formigas (Hymenoptera: formicidae) em cultivo de videiras no município de São Roque - São Paulo

The cultivation of grapes is one of the most traditional cultures and the world's oldest one. In Brazil, cultivars occupy an area of approximately 90 thousand hectares, covering the south, southeast and northeast, in latitudes ranging from 30 º 56 '15''S up to 5 º 11' 15''S. The culture of the vine may be the target of the attack of some diseases and pests, and currently the main concern for growers is the subterranean mealybug, Eurhizococcus brasiliensis (Hemiptera: Margarodidae), known as pearl-ground. This arthropod infests the roots causing a progressive languish of the vine, even causes its death. In southern Brazil it is known that some species of ants can disperse pearl-ground for short distances, however, there is no information about that in the State of Sao Paulo. Thus, it is extremely important to perform studies with this focus on wine regions in this State. Therefore, this study aimed to identify the species of underground ant community in different grape varieties found in vineyards in the town of São Roque – SP, Brazil. With that purpose, samples were collected within one year. We used underground pitfalls spread across twelve points. In each of the points were placed two traps, one containing honey and the other containing sardine as attractive. The results revealed the presence of three morphospecies of ants in Niágara Rosada and four in other grape varieties, there was no significant difference in the species richness among the cultivars (Kruskal-Wallis - 0.33, p = 0.5). In both trials, the most frequent species was Brachymyrmex sp.4, suggesting that there is no dominance of distinct species of Niágara Rosada and the other grape varieties. There was no dissimilarity in species richness of the ones visiting honey or sardines (Kruskal-Wallis - 0.08, p = 0.7) and the analysis of variance indicated a great similarity in species richness between the rainy and dry seasons (Kruskal-Wallis - 0.09, p = 0.7)

Os movimentos nas redes e em redes: das manifestações internacionais ao Movimento Prudente

Neste trabalho apresentamos uma leitura sobre o processo de articulação dos movimentos em redes e do uso das redes sociais pelos movimentos socioespaciais que mais se destacaram no mundo nos últimos cinco anos. Tendo suas bases nos marcos conceituais de movimentos socioespacial, movimentos socioterritorial, Rede e Redes Sociais, remontamos ao processo de formação da Via Campesina e das manifestações na Primavera Árabe, M12M, M15M, Occupy Wall Street, Movimento Passe Livre e o Movimento Prudente na escala local. Analisar e comparar estes movimentos e suas manifestações nos permitiu identificar a conexão entre a difusão de informações nas redes sociais e a materialização das manifestações no espaço público. Destaca-se que o uso destas tem acarretado em uma nova dinâmica não só na difusão de manifestação, mas também na realização de trabalho de base, caracterizando-se como um importante espaço de socialização política da atualidade

Angiografia comparativa, prós e contras entre os métodos: por raios-X, Tomografia Computadorizada e Ressonância Magnética

By the early 20th century, the blood vessels could only be seen by anatomical studies. Shortly after the discovery of X-rays by Conrad Roentgen in 1895, the first experiments with radiographic imaging were performed with blood vessels. In 1905, the first experiment involving catheterization of arterial and venous system in dogs was performed and only in 1914 performed on living human patients. Parallel to these landmarks, there were advances in diagnostic imaging devices and the evolution of contrast substances was of utmost importance to the current angiography occupy a prominent role not only in terms of diagnosis, but also in the treatment of various disorders. The main objective of this review is to weave historical considerations and comparisons between the different methodologies used in angiography, because its importance; that may be in future, a veterinary diagnostic decisive test

Influência da luz LED em culturas de células-tronco mesenquimais in-vitro

Stem cells are defined as cells capable of self-renewal and differentiation into specialized cells when submited to external signalings in the enviroment. Among adult stem cells, mesenchymal cells occupy an important position because they can differentiate into mesodermal cells such as osteoblasts, adipocytes and chondrocytes. Cell therapy consists in the use of mesenchymal stem cells (MSC) in the treatment of degenerative diseases and harmed tissue reconstruction. Due to the longstanding and costly procedure for cultivation of MSC, it was proposed the use of low power light sources, such as light emitting diodes (LED), to optimize these factors. Recent works have shown a series of results from the influence of LED light on biological tissues such as increased rate of cell proliferation, increased RNA, DNA and ATP synthesis rate. The purpose of this study is to compare the biomodulator effect of LED light set at wavelengths 630nm ± 10nm and 805nm ± 10nm on the mesenchymal stem cells proliferation. For this, the mesenchymal stem cells culture adopted the procedure used in the Departament of Animal Reproduction and Veterinary Radiology of the Faculty of Veterinary Medicine and Animal Sciences of Botucatu. MSC were obtained from an adult horse bone marrow, and isolated by density gradient separation, with the FICOLL reagent and by centrifugation. The pellet containing the stem cells was removed and these were placed in low glucose DMEM culture medium, containing 10% fetal calf serum and antibiotics. The material was observed daily by inverted microscopy for monitoring the progression of the cells and subsequently the amount of cells were counted in a Neubauer counting chamber. The amount of MSC was obtained by cell culture seeded in 24 wells culture plate and segregated into three distinct groups: Group 1 was irradiated with wavelength set at 630nm ± 10 nm, Group...

O ensino de redação em sites: diálogos em rede

We know that studies on reading and writing take place within the Linguistic for several decades and, with de computer, the language entered the network and this is opening a learning space for writing classes, no more reduced to a classroom but expanded to a universe that has no geographical boundaries, namely de Internet. Our research fits into this context and is part of the project The discourse on writing practices in contemporary Brazilian media: the art making, the pedagogical practice, and the production of meaning to develop discourse analysis on the practice of writing on sites dedicated to teaching and learning of this practice. The main objective of this research is to investigate the relationship between school attendance of redaction - made here as discourse gender, as you know Bakhtin - and the discourse of the sites that constitute our corpus. We set out the hypothesis that the sites are intended for the teaching/learning of writing seeking to create virtually teaching imaginarily conditions similar to those that exist in school attendance of the Portuguese language. We are interested in, therefore, observe, discursively, as the image is created of the interlocutors to which they are intended considering that the enunciators are not in front of those who occupy the place of real students, because they are virtual students. We, too, to know as the gender class manifested itself in those sites, as these sites dialogue with the face-to-face class in relation to ideology, the function of the teacher, the conception of language and writing. The constitution of the corpus was from search tools on the internet. The sites that we analyzed were: alunosonline.com.br, brasilescola.com.br, coladaweb.com.br, guiadoestudante.com.br, infoescola.com.br, mundoeducação.com.br, mundovestibular.com.br, português.com.br, professorjuscelino.com.br and redaçãodissertativa.com.br. The selection was qualitative, considering the...

Convivendo com o lixo: a vulnerabilidade socioambiental no bairro Jardim Graminha, Leme, Sao Paulo

Urban space occupation occurs in an extremely disordered way. Political, economical and social aspects converge to create a problem that affects mostly poor people who are impelled to occupy areas where social and environmental problems are likely to emerge. Floods, landslides and different forms of pollution have more effects on the most vulnerable groups. In many cases, actions taken by the government legitimate this structure and reinforce its reproduction. This work seeks to confirm both that poor people are vulnerable to social and environmental problems resulting from inappropriate urban solid waste disposal and that the local government contributes to this situation. It is assumed that the issue is related first to the government’s disregard for poor people who live in unhealthy places and, second, to the inability of such people to demand for better living conditions. In this study, a waste disposal area within Jardim Graminha neighborhood in Leme (São Paulo) was selected to be analyzed by means of systematic observation. The study clearly shows that poor people living near that area where different types of garbage are disposed are vulnerable and the government does not control the situation. It is also pointed out that governmental intervention and the use of political and technical tools are necessary for planning and managing the area to mitigate these problems and to decrease poor people’s social and environmental vulnerability.

A indústria de defesa brasileira: o setor de carros de combate e a engesa

This paper analyzes the small and medium armored combat vehicle industry, in order to understand its modus operandi. We investigate the former largest Brazilian producer of small and medium armored combat vehicles, Engesa, and concluded that its world success was a result both of its privileged perception to occupy a market niche and of the special relationship among its CEO and the Brazilian Army. A combination of negative factors conduced the firm to its bankruptcy, in the beginning of the 1990s, but we also identified a huge business potential, which could be either occupied by Engesa, if it had not disappeared, or by a follower in this market.
