The present study undertakes teaching tactile response to four infants, ages 26-29 months, with limited exposure to verbal stimulation. The decision to teach tact response is based on the concept that it is one of the most important categories of verbal operants, therefore, a strong aspect of their control is dependent upon the antecedent stimulation in the physical environment. By controlling the child s antecedent environmental stimuli, she then has a wide variety of circumstances for learning, and, as a result, can enhance her verbal repertoire. In order to verify whether tact learning could enhance conditional discrimination learning, a pairing procedure Matching to Sample Auditory-Visual (MTS) was used as a measure of discrimination learning, plus interlaced tact training. In this manner, two teaching procedures were performed: teaching of vocal tact and MTS. Two babies began training with vocal tact, and two begain with MTS. The tact training consisted of instruction/commands by an adult as a condition for the issuance by the baby of: echoics, selective responses and vocal tact responses. The results indicated that the cumulative curves for solicitation of echoics and selection by the researcher and the corresponding curves for the correct responses by the children had gradual positive acceleration. The performance curves of each of the babies, relative to tact, presented a more accentuated curve relative to the cumulative curves for tact requests by the researchers. The data suggest that the teaching of tact response to the tact command can be considered the more exigent task, compared to the demands of echoic and response selection, ahead of vocalization of the object s name. The results warrant discussion of the concomitance of learning echoic response and selection of objects upon vocalization of the name. The outcome of the MTS is that the four participants achieved the learning criterion for the discrimination of presented stimuli. In the statistical analysis of the correlation between percentage of hits with MTS and the percentage of correct responses in the three tact teaching situations, the results indicate that three of the four participants had a directly proportional relative increase between the MTS correct responses and selection solicitation correct responses. For just one participant, the statistical analysis indicated an higher correlation between the tact solicitation correct responses and MTS correct responses, however, this participant required a greater degree of behavioral listener-speaker training with familiar objects. The teaching method used, which interlaced tact training with MTS was as effective for teaching vocal tact as for teaching conditional discrimination.

The aim of the present study was to investigate the effect of swimming and resistance training exercise on adipose tissue, inflammation and lipid profile in highfat feeding rats. Wistar adult male rats were divided into 6 groups (n = 10 per group): Sed-C, sedentary chow diet; Sed-HL, sedentary high-fat diet; NT-C, swimming chow diet; NT-HL, swimming high-fat diet; TF-C, resistance training chow diet; TF-HL resistance training high-fat diet. An 8-week training period was used. During it period the animals of resistance training groups climbed a 1.1-m vertical ladder with weights attached to their tails. The sessions were performed once every 3 days, with 4 9 climbs and 8 12 dynamic movements per climb. Swimming groups performed 60 min/day, 5 days a week, with a constant overload of 5% body weight during 8 weeks in tanks of 50 cm of height and 30 cm of diameter. High fat-diet increased body weight, relative weight of adipose tissue (epididymal, retroperitoneal, visceral and subcutaneous) and adipose tissue area (epididymal, retroperitoneal and visceral). There was higher TNF-alpha expression and lower (not significant) IL-10 expression in visceral adipose tissue and negative change in lipid profile because of the high-fat diet. Resistance training presented lower values of visceral and retroperitoneal adipocyte area, lower TNF-alpha expression and changed lipid profile. Swimming presented lower epididymal and retroperitoneal adipocyte area, higher IL-10 expression and changed lipid profile. These results indicate the potential benefits of resistance training and swimming as non pharmacological alternatives to control the effects of high-fat diet on adipocyte area, lipid profile and inflammatory process in rats.

In this work, we extend some global L1 estimates proved by Bourgain-Brezis in the case of the de Rham complex on RN to the setup of local L1 estimates for elliptic complexes, namely, those associated to involutive elliptic structures spanned by a family of linearly independent smooth complex vector fields. In particular, we obtain a local version of Gagliardo-Nirenberg estimates for elliptic systems of vector fields.

In this thesis, we explore two sort of quantum correlations: entanglement and quantum discord. We present a geometric method to identify and measure the degree of entanglement based on symmetries of vectors and matrices associated with the two-qubits density operator of quantum states. We introduce a new basis of parameters describing the density operator, and this procedure allows us to establish the Peres-Horodecki separability criterion in terms of squared distances that obey the Minkowski metric, giving a more general interpretation of this criterion as well as building a quantifier of entanglement. In this method, if the squared distance is of the kind timelike, i.e. non-negative, the two-qubit system is separable. Otherwise, if it is spacelike, namely, the squared distance is negative, the two qubits are entangled. Such squared distances are invariant by unitary transformations and can be represented graphically in a hyperbolic parameterized phase space, allowing a suitable graphic representation, i.e., in a phase space where the system trajectories can be drawn. The method is generalized to a larger class of states having at most seven independent parameters, the D-7 manifold class. Using group theory methods we classify these states according to the symmetries of seven generators, where one of them commutes with the others. We illustrate the method and the theory by presenting several two-qubit systems found in the literature. This same notation is used to calculate the quantum discord for states whose 4 × 4 matrices belong to the D-7 manifold class, providing a more explicit condition of minimization of entropy. We calculate the dissipative dynamics of two-qubits quantum discord under local noisy environments. Choosing initial conditions that manifest the so-called sudden death of entanglement, we compare the dynamics of entanglement with that of quantum discord and we show that in cases where the entanglement suddenly disappears, quantum discord vanishes only in the asymptotic limit.

Brazil has a rich fauna and flora, for these reasons it is called as mega-diverse country. This diversity enables the isolation and identification of substances that become promising in several areas and an example is the insecticidal activity of various substances in agriculture. This study presents the identification of volatiles from leaves, the phytochemical study and insecticidal and fungicidal test of fractions of organic extracts of Astronium graveolens (Anacardiaceae) that belong to the Order Sapindales. Among the fractions tested against leaf-cutting ants (Atta sexdens rubropilosa) and their symbiotic fungus, Leucoagaricus gongylophorus, ethyl acetate fractions of ethanolic extracts of roots, stems and branches showed good activities. In parallel was evaluated the action of those fractions against Spodoptera frugiperda, however, those fractions did not showed promising activities. Phytochemical study of ethyl acetate fractions resulted in the isolation of 11 secondary metabolites, two flavonoids: 5,3',4'-trihydroxy-7-methoxyflavone and myricetin-3-O-_-L-rhaminosídeo, three phenolic compounds: epigallocatechin methyl ester, 5-O-caffeoylquinic acid, 3- O-galoil-5-cafeoilchinic acid (inedited); six dimeric chalcones, (7S,8"R)-(2',4,4',5, tetrahydroxychalcone-(2_7",8_8 ')-2' ,4",4"'-trihydroxy-7",8"-dihydrochalcone; (7R,8S,7"S,8"R)-2',4,4',5,7-pentahydroxy-7,8-dihydrochalcone-(2_7",8_8")- 2 ',4",4"'-trihydroxy-7",8"dihydrochalcone; (7S,8R,7 S,8 S)-2',4,4',5,7-pentahydroxy- 7,8-dihydrochalcone-(2_7",8_8")-2 ',4",4"'-trihydroxy-7",8"-dihydrochalcone; rel- (7S,8S,7"S,8S)-tetrahydro-7,7''-bis-(4-hydroxyphenyl)-7,7''(furandil)-8,8,2.4''- dihydroxiphenyl;4,5,4 dihydroxy-7,2 -oxo-chalcone-(2_7 ,8_8 )-2 ,4 ,4 ,2 ,4 - trihydroxychalcone; 4,4 dihydroxy-7,2 -oxo-chalcone-(2_7 ,8_8 )-2 ,4 ,2 ,4 - tetrahydroxychalcone . The dimeric chalcones are new to the genera and, except first one, in the literature.

Decreased levels of estrogen are associated with hepatic steatosis (HS), through changes in gene expression of molecules related to fat oxidation and lipogenesis. Both resistance training (RT) and endurance training (ET) prevents the HS in ovariectomized (Ovx) rats. However, the molecular events associated with this process were only investigated for ET but not for RT. Aims: Thus, the aim of this study was to investigate the effects of Ovx and RT on the gene expression of molecules related to fat oxidation and lipogenesis in the liver of rats. Methods: Sprague-Dawley adult female rats were grouped into four groups (n = 6 per group): sham-operated sedentary (Sham-Sed); Ovx sedentary (Ovx-Sed); sham-Rt and Ovx- Rt. A 10-week RT period, during which the animals climbed a 1.1-m vertical ladder with weights attached to their tails, was used. The sessions were performed three times a week, with 4-9 climbs and 8-12 dynamic movements per climb. Gene expression was analyzed by RT-PCR by the ΔΔCt method. Results: The estrogen deficiency associated with ovariectomy decreased the gene expression of molecules related to fat oxidation, carnitine palmitoyltransferase I (53%) and β-hydroxyacyl-CoA dehydrogenase (27%), and increased of molecules related to lipogenesis, sterol regulatory element-binding protein-1c (106%), acetyl-CoA carboxilase (ACC) (72%) and stearoyl CoA desaturase-1 (109%), which had their expression restored to the RT, with the exception of the ACC. Conclusions: The present results indicate that the RT may have important effects on the prevention of HS in Ovx animals, possibly through the restoration in gene expression of molecules related to hepatic lipid metabolism

The present work describes the syntheses and characterization of complexes of general formula [Ru(AA)(P-P)(N-N)]PF6 where AA = aminoacids (Gly, Ala, Val, Met, Tyr, Trp, Leu, Arg, Ser, Lys, His); P-P = 1,4- bis(diphenylphosphino)butane and 1,3-bis(diphenylphosphino)propane; N-N= 1,10- phenanthroline, 4,4 -dimethyl-2,2 -bipyridine, 5,5 -dimethyl-2,2 -bipyridine e 4,4 - methoxy-2-2'-bipy. The complexes were evaluated against cell lines MDA-MB-231, MCF-7 (breast tumor cells), DU-145 (prostate tumor cells) and in FGH and V79 (fibroblasts, normal cells), HeLa (colon tumor cells), as well as antimicrobial tests (tuberculosis) and antiparasite (malaria (CW-2 chloroquine resistant) and Chagas disease (Y-form) ). By analytical techniques such as elemental analysis, UV-vis and infrared spectroscopies and nuclear magnetic resonance (31P{1H}, 13C{1H} and 1H), it was possible to confirm the proposed structures for the synthesized compounds. By the 31P{1H}, 13C and 1H NMR spectra, it was suggested the presence of isomers, these data combined with the X-ray structure analysis of the [Ru(LLeu)( dppb)(bipy)]PF6, allowed us to conclude that those isomers are diastereoisomers. The cyclic voltammograms of all the complexes are similar with the first anodic wave around 1.1 V being attributed to the oxidation RuII→RuIII, and the second anodic wave, in 1.2 V, is attributed to the oxidation of the COO- group of the aminoacid ligands. In the IR spectra of the complexes, characteristic stretching bands of the group NH2 and COO- were observed, which are found shifted to higher frequencies when compared to the free aminoacid. The complexes here studied presented promising results against diseases evaluated. The values of the IC50 for some of the compounds showed 31,5-fold lower than the cisplatin. The antimycobacterial tests were satisfactory, since the complexes showed lower MIC values than some drugs actually used in the tuberculosis treatment. Considering the antiparasitic tests, low IC50 values were also observed.

The manual translation of a source natural language into a target natural language is a task that demands time and expertise. In order to reduce the work needed for manual translations, the aim is to accomplish this task through Machine Translation (MT) systems. Since the 1940s, various approaches and techniques of MT have been proposed, investigated and evaluated in order to improve the quality of translations generated automatically. Nowadays, statistical machine translation methods are considered the state-of-art regarding the evaluation automatic measures commonly used in the area (such as BLEU and NIST), however a recent trend indicates that such systems will not improve their level of performance without the application of deeper linguistic knowledge, for instance, syntactic information. Thus, as an attempt to support the building of automatic translators, this dissertation presents the research, the implementation and the evaluation of parse trees alignment techniques. The computational tool for the automatic alignment of syntactic trees, result of this work, may be used to generate an extremely useful resource for various MT techniques: the aligned syntactic trees . This resource, so far unavailable for Brazilian Portuguese, will allow the development of new researches, which can provide the scientific advancement of the area. In this dissertation, a study of various techniques for parse trees alignment from the literature is presented. Besides, the pre-processing of a corpus for the inclusion of syntactic information from which the alignment is performed is also described, as well as the phases of lexical alignment and syntactic analysis. Some implementations and tests have been carried out with the pre-processed corpus, based on the theoretical foundations derived from the study of the techniques proposed in the literature. Based on the results of the intrinsic evaluation of the alignment, it was possible to conclude that the alignment of syntactic trees reached the accuracy of 97.36% and the coverage of 93.48% for tree pairs, representing parallel sentences in Brazilian Portuguese and in English by using different settings. Since the results have been promising, as future work, the aim is to apply the tool to a larger corpus of parallel syntactic trees, in order to obtain more examples of translation and, thus, allow its application to syntax-based machine translation techniques, such as syntax-based statistical methods or data-oriented translation.

Both the mercury (Hg) and their compounds are recognized as important pollutants, because they are persistent, bioaccumulative and toxic. The largest sources of mercury pollution are chloride-alkaline industry and gold mining. The growing contribution of Hg in aquatic environments results in high accumulation of mercury in fishes tissue and their consumers, which poses a serious risk to humans and ecosystems. The aim of this study was to evaluate the effects of acute exposure (96 hours), via water, and a sub-chronic exposure (30 days), via food, to sub-lethal doses of inorganic mercury (HgCl2) in two species Brazilian fishes ecologically distinct, matrinxã (Brycon amazonicus) and traíra (Hoplias malabaricus). The cardiorespiratory responses to normoxia (140 mmHg) and graded hypoxia (120 - 10 mmHg), cardiac contractility in vitro, biomarkers of oxidative stress and the potential for bioconcentration and biomagnification were analyzed. The results show that exposure of these species to HgCl2 induces oxidative stress in different tissues, limiting the maintenance of cardiac contractility by reducing the force of myocardial contraction and modulates the response pattern of cardio-respiratory variables to graded hypoxia front, making the species more susceptible to environmental variations of O2. Regarding matrinxã specifically, the critical points highlighted were mainly severe oxidative stress in heart and white muscle; marked reduction of contraction force of isolated heart muscle; hyperventilation and increase the value of the critical tension of O2 in more than 100%; and intense bioconcentration in all tissue whose values exceeded the maximum allowed. In the case of traíras the results were: oxidative stress in the liver and gills; hypoventilation; decreased in metabolic rate and O2 extraction; and bradycardia with impaired electrical conduction as first degree atrioventricular block and lengthiness of the potential plateau action of cardiac muscle. Therefore, the data indicate that mercury via food or water and in environmentally relevant concentrations, can have a negative impact on behavior, health, performance and success of the species, making their survival and/or vulnerable populations.

Changes in vectors that indirectly affect biodiversity, including population, technology and lifestyle, may lead to changes in vectors that affect biodiversity directly, including fishing and fertilizer application. This result in changes in ecosystems and services they offer, affecting human well-being. These interactions can occur in more than one scale. Different strategies and interventions can be applied in many parts of this structure in order to ensure the well‐being and conserve the ecosystems. Traditional communities have their way of life related to their living environment, and recently have been studied in order to ensure sustainability with a focus on human well‐being based on the Millennium Ecosystem Assessment, in order to implement the established in the National Politics of Sustainable Development to Traditional Peoples and Communities. This study was conducted at the Fishermen Cooperative and Artisans of Pai André and Bonsucesso (Coorimbatá), which gathers people from the urban area of Cuiabá and riverine communities of Bonsucesso and Pai André, located in Várzea Grande, Mato Grosso, to assess the strategies adopted by Cooperative for the well-being of the cooperative members and the use of natural resources of local biodiversity. The study s hypothesis is that the way the Cooperative Coorimbatá was structured from the amendment of its Statute in 2000, meets the fundamentals of the Millennium Ecosystem Assessment with regard to the conservation and sustainable use of ecosystems. It also contributes to creating environments for dialogue and action for the sharing of knowledge between traditional peoples and academics, looking forward the human well-being. The method used to prove whether or not this hypothesis has the qualitative research approach to data sources in semi-structured interviews with the founders of the Cooperative Coorimbatá and fishermen from Bonsucesso and Pai André communities, projects and reports made by Coorimbatá. Within an ergological focus, were also made visits to local fishing community of Bonsucesso, with interviews by the self-confrontation method, to obtain additional information to better understand this phenomenon. The semi-structured interview was made from a questionnaire with questions regarding: life history; Cooperative Coorimbatá meaning; type of work, leaders identification, Cooperative s expectations. Initially, the Cooperative main product was fish, however due to this natural resource is no longer available as it was in previous years, the Cooperative began to add other products in its supply chain as fruits raisins (dried), cassava chips, brazilian nuts and more recently the alligator. Know and reveal the lifestyle of these members, their relationships and interactions with the river are important tools to be used in discussions and implementation of public politics.

A necessary condition for the economic efficiency of modern plants is the ability to adjust - as quickly and effectively as possible - the performance of manufacturing process for demand request decisions. In this sense, the research emphasized the importance of understanding the best practices in Information Technology (IT) and the trade scenario of solutions using shopfloor real data in virtual environments for simulation and many achieved benefits. The highlights of this research focused on exploring the collaboration (practice of skills for the achievement of mutually beneficial results) between the MES (Manufacturing Execution Systems) and the digital manufacturing systems (also called virtual manufacturing systems) of PLM (Product Lifecycle Management), in a scenario where the manufacturing processes require high flexibility, reliability and lower delivery times, extensive combination of variants and lower life-cycle of products. The research - in an exploratory and descriptive way, which identified the available knowledge on the subject more sharply between the years 2006 and 2010 - was grounded in the practices of world-renowned companies and institutions and considered opinions and evaluations of renowned researchers and professionals with expertise in initiatives to support the use of MES solutions data in systems of digital manufacturing of PLM to manufacturing processes planning. As a result of the studied scenarios and covered concepts, the research has consolidated a "diagram of information collaboration", with the aim of providing better decision choices within the framework of shop-floor project, processes planning and production management. The research also concluded that the MES systems may have their value extended if integrated within the characteristics of functionalities of the PLM concept. It also brought some recommendations and limitations on the portability of information, commented on the learned lessons and suggestions for future tasks that include the BPM (Business Process Management).

This dissertation addresses issues of emigration flow in the city of Gonzaga (MG). The city was featured in the international media world in consequence of the death of a citizen in September 2005, Jean Charles de Menezes. The young man was killed in a London subway station (England) after the British police have mistaken for a suspected terrorist, the event resumed debate on the problematic conditions which thousands of immigrants are exposed. From the anthropological perspective, the survey reports the social dynamics of the city, focusing on the notions of family and local traditions. So this ethnography describes families in their organization and values, which influence emigration flow.

The present work describes the study of variation in the chemical profile of citrus after inoculation of Xylella fastidiosa, in charge of the Citrus Variegated Chlorosis is one of the most serious diseases that cause damage in Brazilian citrus. The bacterium X. fastidiosa was inoculated in Citrus sinensis grafted on C. limonia and was evaluated using chemometric tools and development of analytical methods such as HPLC-DAD, LC-MS/MS, LC-UV-SPE-NMR and HRMAS quantitative variation of some secondary metabolites such as coumarins and flavonoids identified both in grafts and in the matrix C. sinensis and C. limonia. The chemometric methods PCA and HCA applied to the data obtained in studies by HPLC-DAD and HR-MAS allowed to discriminate plants contaminated with the bacteria of the species healthy, as well as the respective individuals. By analyzing the change in the chemical profile of citrus studied by HPLC-UV-SPE-NMR it was possible to detect the presence of a new class of secondary metabolites derived from p-hidroxy-cinnamic acid containing oxidized dihydropyran and dihydrofuran rings. Similarly, when analyzing the compounds of medium polarity by LC-MS/MS technique was identified, until now, in the roots and leaves several coumarins not cited in the literature for any of the species that constitute the graft, as dihydrosuberenol, 2 ', 3'-dihydrosuberosin, citrubutin the limonoid diosfenol limonin and flavonoid 3-hydroxy-3', 4 ',5,7,8- pentamethoxyflavone. Finally, was observed that coumarin bergapten is present in reasonable quantities only in the leaves of Rangpur lime, which is tolerant to X. fastidiosa, and when the graft presents with symptoms of citrus variegated chlorosis is a small production of this in their leaves, indicating that this is a phytoanticipin.

The immature females of twelve species of Ceroplastinae (wax scale insects) were described and compared, macro and microscopically, with the purpose of contributing to the understanding the groups of the species of this subfamily, whose generic status is controversial. The morphology of the immatures, although little studied and not yet used in the phylogenetic studies of this subfamily, was very important for the grouping of the studied species. Nymphs of the first and second instars varied widely in relation to the wax test and the stigmatic setae, separating the species studied in three main groups: I) C. cirripediformis Comstock, 1881, C. floridensis Comstock, 1881, C. formicarius Hempel, 1900, C. grandis Hempel, 1900, C. mosquerai Ben-Dov, 1993 and C. rusci (Linnaeus, 1758), with dry wax filaments and with cylindrical or slightly conical and conical stigmatic setae with rounded apex in the first instar and setae totally conical in the second instar; II) C. formosus Hempel, 1900, C. janeirensis (Gray, 1828) and C. lucidus Hempel, 1900 with a shell of wax glassy and absence of lateral expansions or dry filaments and with stigmatic setae cylindrical with rounded apex and wider than the base, in the two first instars, and III) C. diospyros Hempel, 1928, C. flosculoides Matile-Ferrero, 1993 and C. iheringi Cockerell, 1895 with intermediate characteristics in waxy covering and setae with pentagonal or irregular shapes. The pattern of wax test observed for the group I, previously mentioned for other authors, was the most frequent among the studied species and better distributed in the world, being probably the most common pattern in Ceroplastinae. The patterns of wax cover observed for Groups II and III are here described for the first time for the immature females of Ceroplastinae. The group II is probably restricted to the Neotropical region, and the group III, including Neotropical species, probably has representative species in the Afrotropical region.

Multimaterial structures are currently a technologically attractive field of research. The growing use of polymer composites replacing metals in structures aiming for weight and emission reduction is part of the motivation of this study. The currently used techniques adhesive bonding and mechanical fastening are limited in certain aspects, opening a path for innovation in this area. Joining of polymers and metals via Injection Clinching Joining (ICJ) is an innovative technique based in injection molding, adhesive bonding and staking. This work studies this technology in its theoretical aspects and applies it to a preliminary study with commercial materials: 30% short glass fiber reinforced polyamide 6,6 (PA66/FG30%); and aluminum alloy AA2024-T351. A design of experiment of one factor at a time analyzed effects of the process parameters on macro- and microstructure, local and global mechanical properties, and thermal properties. It was possible to create joints in which the polymer completely filled cavities in the metallic hole, but the reproducibility was not good, for most joints had only partial filling of the cavities, factor which improves the mechanical performance of the joint. The lap shear testing of overlapped joints determined the global mechanical strength of the joint, which ranged from 20,90 MPa to 51,48 MPa (35,9% to 88,5% of the ultimate tensile strength of PA66/FG30%), and the best performances are attributed to a large contact volume of polymeric material with the chamfer on top of the stud, and effective cavity filling. Two types of fracture were observed, a ductile and gradual (rivet pull-out), and a fragile and catastrophic (net-tension). The thermal properties of the polymer after joining were not significantly changed compared to the base material. This scientific and technological research featured ICJ as a viable process for joining of multimaterial structures, achieving good mechanical performance without significantly changing the properties of the base materials.

The usage of wireless sensor network is increasingly being applied to people s everyday lives everywhere: from energy consumption in households and buildings in general, to vital signs in assistive medicine, infrastructure monitoring, chemical or biological product leaking detection in industries, better surveillance, environmental monitoring, among many others. WSN can be deployed in different densities next to several thousands of nodes. However, the development of WSN solutions are limited mainly by energy resource restriction. The great challenge to WSN solutions is to increase the network longevity while guaranteeing data delivery, reliability and accuracy in an environment prone to different types of failures. The largest source of energy consumption is data transmission. Thus, solutions to WSN needs to avoid intense communication keeping energy consumption balance and so the network longevity. In applications in which high density of nodes is necessary, sensing process can produce a large amount of data which are similar or redundant, due to the special proximity among the nodes. This spatial proximity can be explored in routing solutions to reduce the amount of messages transmitted throughout the network. This work presents the Spatial Correlation Aware Routing Protocol - SCARP , which makes use of spatial correlation to reduce the number of network transmissions. With SCARP, the WSN is configured in cells and nodes of each cell are selected, in an alternated way, to transmit similar or redundant data, and so reducing the number of transmitted messages. This traffic reduction results in less energy consumption and longer network longevity. Evaluation results show that SCARP outperforms similar solutions described in the literature, such as DAARP, which uses clustering and aggregation. SCARP has a positive performance even for large node density scenarios.

Streams and rivers are loctic environments characterized for a strong and unidirectional water flow. These environments in general have the light incidence partial or totally obstructed by the canopy of the riparian vegetation showing a high dependence of allocthonus organic inputs. The stream fishes are usually small sized, with reproductive strategies adapted to the unstable environment and have great trophic plasticity. The endemism is very common in this ictiofauna. The studies on trophic ecology and resources partitioning are important for the understanding of the community dynamics in the environment and the maintenance of the species. The Lapa Stream Watershed is located in the central region of the São Paulo State on area of basaltic cuesta relief. The surroundings of these streams are relatively well preserved and the main economic activities of the region are farming and ecotourism. This study was performed throughout four seasonal fish collections, carried out between April of 2002 and February of 2003 in the diurnal and nocturnal periods. Twelve collection stations were distributed in Lapa and Cantagalo Streams and in Passa Cinco River and sampling were made using cast nets, baited traps, sieves, and gill nets. The diet of 29 species were studied and it was found that insetivory was the main alimentary habit, followed by iliophagy - algivory and omnivory. The alimentary overlapping was high in several species pairs, but the habitat segregation occurred in some of them. The diet of three species altered along the upstream downstream gradient. The patterns of simpatry had been analyzed in three genera: Bryconamericus, Apareiodon and Astyanax and the food was the main resource partitioned among these species followed by the space resource. The results had shown that the micro basin is still well preserved, but that investments in the maintenance and recovery are necessary.

Sport is one of the most developed contents in physical education classes in schools; nevertheless, it doesn‟t get the necessary pedagogical treatment for its better use as an educational instrument. In order to be truly democratic, it has to be adapted to the students needs and possibilities. Volleyball as a team sport creates confrontational and cooperative situations that can be done in a pedagogical way by the teacher. With the same objective and dynamics, the adapted sport Sitting Volleyball is able to facilitate positive actions in interpersonal relations, in which the possibility of success during school sports development may be more evident among students with and without physical disabilities. The present study aimed to systematize, put into practice and analyze a teaching program conceived to teach sitting volleyball to students with physical disabilities through games played in a sitting position, as a strategy to sensitize people to include physically disabled students in physical education classes at elementary school. From a pedagogical focus, the development of this study was supported by quantitative approach theoretical references and it is configured as a case study. The study was conducted in public schools of a medium-sized country town of São Paulo state. There were 120 participants from the fifth and sixth grades at elementary school, from three different groups of physical education classes with at least one physically disabled student included in each group. The instruments used for data collection were: a) observation protocol; b) beginning and ending questionnaire. In every class there was also the Field Notes filling to support the data quantitative analysis. The data collected and analyzed showed that in 98% of the developed activities, the possibilities of interpersonal relationship happened in a positive way among students with and without physical disabilities, promoting joint participation in conditions and possibilities of similar success that aroused concepts and values which enabled the accomplishment of the inclusive work.

Due to the lack of appropriate definitions, criteria and methods, the scientific literature in special education in Brazil has always highlighted the need to develop assessment procedures with certain standards that should be available to identify students with intellectual disabilities. This uncertainty is reinforced by the lack of consensus on the methods of identifying and labeling students with learning disabilities. However, the prospect of school inclusion, which encompass strategies and practices that support and enable meaningful inclusion of disabled students into the mainstream of the school system, similarly requires identification to meet the eligibility criteria stipulated by Specialized Educational Services (ESA). Whereas within the category of intellectual disability almost half of all pupils with special educational needs are enrolled, and that this figure greatly impacts the funding received from educational systems, due to the FUNDEB allocated the double of the amount in education budget aimed directly at students with special educational needs, there is a concern that there might be some form of reprisal regarding the criteria used to identify these students. The aim of this study was to describe the evaluation process in the identification of students with intellectual disabilities in Sao Paulo State. The study began with an analysis of official documents, policies and procedures that govern student assessment processes designed to identify pupils with special educational needs in Brazil and in São Paulo State, and it was concluded that there is a lack of clear guidelines and definitions for the assessment of intellectual disability and therefore the consequences are unknown. An empirical study was developed encompassing five towns in São Paulo State, in three instances regularly engaged with the identification of these students: the municipal, the state system, and the special school, a total of 15 data collection sites. The study was divided into three phases designed to: ethical conduct and preliminary assessment, characterization of professional skills, and the investigation on their practical assessment to identify their strength and previous experience. Focus group interviews were conducted on a regular basis with the availability of a team of professionals that allowed the assessment and individual interviews where only one professional was responsible for the results. Data obtained from interviews with 67 professionals were analyzed using the Collective Subject Speech (CSS) technique. The results indicate that the regular classroom teacher is the key agent in the early identification of a suspected intellectual disability: developmental delay, learning difficulties, adaptive behavior, and behavior problems. While there is a multidisciplinary assessment team in special school to evaluate students for the diagnosis, conversely, in the municipal and state schools there is an education team that uses the assessment techniques with pedagogical purpose. The procedure used encompassed interviews with families, educational evaluation, multidisciplinary assessment, and intellectual assessment. The latter was applied only to a few special schools. The state education system was the most precarious instance due to the professional shortages, usually recognized only by the special education teacher. Comparing the 15 instances there is evidence that there are no common guidelines in the assessment process, because the number and training of professionals involved vary between different locations, the concept of intellectual disability is subjective, criteria and procedures found in the literature are not followed, and each group develops its own evaluation procedures. Overall, the contradictions between professional discourses and everyday practice is released and they examines the disadvantages of labeling a student that is unnecessary and injurious, even though they are officially labeled for school census purposes and seen as such by schools, often without their and their families knowledge and consent. The need to standardize the evaluation process for identifying students with intellectual disabilities to avoid the arbitrariness and subjectivity that surround this entire process these days is also discussed.

The search for microorganism that produces cellulolytic enzymes is of the great importance in contributing to the viability of biological route for the production of cellulosic ethanol. Among filamentous fungi, the genus Trichoderma is characterized as a high enzyme producer. Given the growing demand for the development of processes that reduce the cost of cellulases had been proposed this work which aims to evaluate and select strains of filamentous fungi Trichoderma, available at Embrapa banks, capable of producing high concentrations of complex cellulolytic enzymes. The methodology developed in the project was divided in four steps until the final selection of the best strains. The first step of evaluation consisted in the observation of the growth of 78 pre-selected strains of Trichoderma from the degradation of microcrystalline cellulose, Avicel. The second step of selection, Congo red test, summarized in the determination of halo hydrolysis and the measurement of enzymatic index (diameter of halo hydrolysis. diameter halo colony-1) of each strain. The third stage was evaluated the strains with greater potential to produce cellulases in fermentation test tubes for the enzymes CMCase, Xylanase e FPAse. The last stage of evaluate and select of strains was solid-state fermentation (SSF). In the first step of selection, 49 strains showed the ability to metabolize the substrate microcrystalline cellulose, Avicel. The Congo red test, the second step, selected the ten best strains obtained with enzymatic indexes above 1.50, ranging from 1.51 to 1.90. In the process of fermentation in tubes were selected three strains with the better production of enzymes among the ten selected on Congo red test, T. harzianum CEN 139, T. harzianum CEN 155 and T. sp CG 104NH. For evaluation the enzymatic production in SSF was held initially a factorial experimental design to select the significant variables in the process. The variables studied were: inoculum concentration, moisture and proportion of sugarcane bagasse. After the CMCAse enzyme analysis was observed the proportion of sugarcane bagasse as a significant variable. From this result it was performed a central composite design for the improvement of fermentative parameters: the proportion of bagasse and moisture. The proportion of bagasse was significant and enzyme activity reached 11.16 UI.g-1 to CMCase. The process of SSF, among three tested strains, selected T. sp CG 104NH as the best producer of CMCase, Xylanase and FPase, with values of 25.93 UI.g-1, 67.17 UI.g-1 and 1.87 UI.g -1, respectively. The correlation coefficient between this process (SSF) and Congo red test was R2 = 0.97, 0.98 and 0.97 for the three enzymes studied, CMCase, Xylanase and FPase respectively. Therefore, it was possible to obtain a linear correlation between these two methodologies. The selection steps evaluated in this study were considered effective, quality selections proved quick selection of an extensive database of fungi. The linear correlation between the tests made with red Congo and SSF indicate that is possible to use the combination of qualitative and quantitative methods to assess the ability of cellulase production by filamentous fungi.
