Addressees the systematization of logistical and commercial aspects of São Paulo s sugar exports through Santos Port facilities. Local political and economical liberal transformations that took place by the beginning of 90 s had seen Estate assets being given to private investments (both in agricultural and port operations). As a result, this new institutional environment allowed the occurrence of hybrids corporate structures to coordinate logistical sugar and alcohol-ethanol exports from inland facilities to the Santos port. The main question is how this adaptation interferes on infrastructural and operational logistics management derived from new transactions within international sugar mayor traders. The main units of analysis are: i) São Paulo s state sugar producers (industrial plants) and port logistics providers; ii) port logistics providers and food trading companies. Results shall foster the comprehension on logistical process and relations amongst the three main actors across the sugar plantsport facilities chain. There are three goals to be achieved: i) identify the total extent of logistical domain across sugar s distributional channels via port of Santos; ii) how logistical assets and processes are developed or provided within those actors; iii) describe the difference among Santos port operations service providers, in relation value-added competitive basis. Theoretical framework blends logistics and supply chain management with foreign trade prospects as a guideline to collect data and empirical evidences. This works object is the São Paulo sugar plants-port of Santos facilities logistics chain.

Nowadays, the microorganisms are responsible for the production of several antibiotics, immunosuppressant and antitumors, furthermore they are extremely important in industrial process. This work describes the production process and the isolation of the citrinin (234,6 mg/L) and of the mycophenolic acid (371,2 mg/L) with high purity levels in the process of extraction of a fermentation of 8 and 12 days respectively of a cultivation in liquid in Czapek medium enriched with 0,2% of extract of yeast utilizing the fungi Penicillium Catl1.1 and Penicillium sp. Casp5, isolated of the Coffea arabica L. after asepsis, as well, the development of an analytical methodology to quantify this compounds using the NMR. Additionally, on this work, we describe the isolation and the structural elucidation of an new alkaloid from prodiginine class with modification on ring (C), from an extract produced by Streptomyces violaceusniger violaceusniger actinomycete, isolated as an endophyte from Zea mays L. leaves and identified by Costa (2005), which was able to inhibit the growing of phytopatogens with economic value (Pythium aphanidermatum, Rhizoctonia solani, Sclerotinia sclerotiorum, Phytophthora parasitica e Fusarium moniliforme). Therefore, Finally, due to the results obtained during the execution of this work, is able to conclude that the Nuclear Magnetic Resonance, beyond be presented like an efficient analytic technique in the quantification of the citrinin and of the mycophenolic acid in the extract fungi, was fundamental in the monitoring and optimization of the conditions of extraction during the period of 20 days of fermentation. Like this, to NMR is a technique that will be utilized in the process production and optimization of the substances produced by microorganisms in industrial scale.

Stretching by the global postural re-education method (GPR) has been widely used as a physical therapeutic procedure for postural alterations, but its action on the cardio-respiratory system has been little documented. However, scientific evidence is necessary to validate it as an alternative treatment. Within this context, three studies were carried out with the objective of verifying the effect of stretching the respiratory muscle chain in the open-arm, open hip joint angle posture by the GPR method on cardio-respiratory responses. Twenty young (22.7±2.5 years old), healthy, sedentary (VO2max: 30.2±4.3 mL.kg.min-1) men with BMI = 25.3±1.5 kg/m2 were studied, divided at random into two groups of ten: the control group (CG) that did not take part in the stretching and the group submitted to treatment (GPR-G). The intervention consisted of two weekly stretching sessions, each of 30 min, for eight weeks, giving a total of 16 sessions. In the first study, the maximal respiratory pressure and the respiratory coefficient were assessed by way of a manovacuometer and thoracoabdominal cirtometry, respectively. Only the GPR-G presented greater values for inspiratory (IPmax) and expiratory (EPmax) maximal pressures and for axillary, xyphoid and abdominal cirtometry after the intervention period. The results showed that the method caused a beneficial effect on respiratory muscle force and on thoracoabdominal mobility, contributing to an improvement in respiratory mechanics. In the second study, pulmonary function was assessed by spirometry. The manoeuvres of slow vital capacity (SVC), forced vital capacity (FVC) and maximal voluntary ventilation (MVV) were carried out. The results showed there was a significant increase in the values for SVC, inspiratory capacity (IC), FVC, forced expiratory volume in the first second (FEV1) and MVV for the GPR-G after the training period, providing evidence that the proposed stretching was efficient in promoting an increase in pulmonary capacity and volume. In the third study, the effect of stretching on the autonomic modulation of the heart rate (HR) and on the ventilatory and metabolic variables was assessed at rest and during the cardio-pulmonary exercise test respectively. The ventilatory and metabolic variables were captured using an automatic metabolic system and the HR using a one-channel heart monitor. The exercise test was carried out using a cycle ergometer, with 20 to 25 W/min increments up to physical exhaustion. Intervention did not change the variables studied either at rest or during the cardio-pulmonary exercise test, for either of the groups. These results showed that the respiratory muscle chain stretching exercise did not promote any adaptations with respect to HR neither at rest and the ventilatory and metabolic variables during the exercise, which could be attributed to the noninvolvement of the major muscle groups in the type of protocol used. Finally, the results obtained in the three studies gave evidence that stretching the respiratory muscle chain by the GPR method was efficient in promoting an increase in respiratory muscle strength, thoracoabdominal mobility and pulmonary function, reflecting in an increase in respiratory mechanics, this fact being attributable to the specificity of the training. In this way, the findings of the present study, reinforce the importance of the GPR method in the maintenance of the functional capacity of the respiratory chain muscles, suggesting that it could be used as an alternative treatment for dysfunctions of the respiratory mechanics.

This study describes the repertoire of social skills and the frequency of externalizing and internalizing behavior problem among children who presented both problem behavior and learning disabilities. The children were evaluated using a variety of measures in social, behavioral and academic domains, using a multiple assessment method (different procedures, instruments and informants) as former reserch points out to a positive bias between children self-evaluation and teacher evaluation. The objectives of this investigation were: (1) characterize the social skills repertorie of children with comorbity of problem behaviors and learning disabilities; (2) characterize the frequency of externalizing and internalizing problem behaviors among these children; (3) compare The social skills self-evaluation to teacher s evaluation; (4) comparing results obtained using two differents instruments for social skills evaluation; (5) Identify the children s special needs, related to the frequency of externalizing and internalizing behavior problem and to deficits in their social skills repertorie. Paticipants were 50 children, 9 to 12 years of age, in the third on fourth grade classes of five elementary public schools, and their teachers, in a small city in the state of São Paulo, Brasil. Three instruments the IMHSC-Del-Prette (Del Prette & Del Prette, 2005), SSRS-BR (Bandeira, Del Prette, Del Prette & Magalhães, s.d.) and TDE (Stein, 1994)-were used to assess the children s social, behavioral and academic skills. Scores were determined according to instructions in each manual and these data were analysed using descripitive and inferential statistical methods. The results show that these children present deficits in their social skills repertorie, along with high frequency of externalizing and internalizing problems. There were biases between self-evaluation and teacher evaluation. This research concludes that children with comorbity of learning disabilities and problem behavior have special needs that are strongly related to their social and behavioral skills deficits.

Self-service companies have been concerned about improving their performance in face of competition, either to conquer new markets or to keep in business. It is essential for them to present good quality products and/or services. Thus, in this study, one of the aims was to show that the waiting time in supermarket checkout lines is very important for service speed and, therefore, for the service level of customers. Other aims include the reasons why the customer goes regularly to a specific supermarket and, among these reasons, the relevance of each one in contrast with the others, and its relative importance. As a result, it was possible to contextualize the scenario in which customers view the importance of queues and their waiting time. Also, the level of schooling of the customers was associated with the factors that lead them to go regularly to the place. This is an interesting contribution because in Brazil there is a relation between income and schooling. Besides, the queueing models that may satisfactorily represent the supermarket checkouts were studied and the one that best represents the system was identified. It was verified that the customers change lines when they notice another line with fewer customers, and the size of this difference was assessed. The queueing model with jockeying was the one to best represent the situation commonly found in supermarkets, and it can offer subsidies for service improvement. In order to carry out this research some companies in the city of São Carlos/SP were contacted, and one among the ones that allowed the data collection was selected. Therefore, this is a case study, thus presenting inferential limitations.

The present study had the objectives to present the characteristics of a complex work, to demonstrate the management of these elements in the everyday job, besides relating this management with the social use of own s body in labor. To achieve these objectives, we studied the case of the domiciliar garbage collectors (garis), in a region of Belo Horizonte, Brazil. This thesis was divided in six chapters, to corroborate the hypothesis that the art of the worker to deal with the complexity of his/her job is the element that propitiates the regulation of workload. Therefore, this regulation can be limited by the personal characteristics of the workers and also for their job, introducing the notion of body economy . This thesis presented the refuse collector s job, the term regulation was differentiated from the term body economy , and some aspects of a complex work were described. The methodology of the Ergonomic Work Analysis (EWA) and some of its techniques were used to get the data. Some of the corporal techniques employed by the refuse collectors in their work were presented and analyzed, according to the complexity of their daily work. The management of the various characteristics of refuse domiciliary refuse collection was demonstrated and, in the thesis discussion was related to body economy . The notion of body economy was deepened, demonstrating the characteristics of the work that make it possible or difficultate the regulation of the workload. Finally, questions for new researches have been raised, and suggested some ergonomics recommendations to improve the conditions of the collectors work. We suggest to the professionals who auto-intitulate ergonomists , should understand the reality of subjects work, before prescribing postures and movements that they consider correct or ideal

The present work aimed to analyze the educational politics implemented for the overcoming of the illiteracy in the Primary Education, in its modality of attending young people and adults, starting from the 1990s. Our central objective was to understand how these programs were delimited facing the direction of the publicization of the social services and the directions from the reforms implemented in Brazil in the 1990s. We took as empirical basis for our study the actions developed in the city of Araraquara in the period from 2001 to 2006, emphasizing the partnership between the City Department of Education and a philantropic entity. We intended to understand how the promotion of partnerships between the public power and the not-state entities can be considered as a factor of excellency for a wider administrative rationality, based in the principles of the effectiveness, efficiency and effectivity of the services offered to the citizens, or whether the partnerships carried through with these institutions affirm the principles of a political culture based on the boundaries of the patrimonialism and the clientelism, structural marks in the formation of the Brazilian State.

This work departed from the finding that the changes occurred in the industrial competitive scenario are in conformity with the unfavorable conditions recognized for the use of the kanban system and that, due to this, the use of this well-known Systems for Coordination of Purchase and Production Orders (SCO) needs to be reviewed. Following, this research aims to evaluate the evolution of the utilization of the kanban system and study the adaptations made in its logic work to adjust it in face to the new conditions, and to evaluate the advantages and disadvantages of these adaptations. First of all, literature reviews regarding kanban system were made, and thirty three different adaptations were studied, classified and analyzed. It was found that, among other topics, the development of the adapted systems, in general, is in an initial stage, once the majority of the proposals are theoretical and might be considered to generate more appropriated practical forms. Afterwards, field research was realized, by means of a survey and case researches. In the survey, it was selected a non-probabilistic sample of thirty companies from São Paulo State that were implementing the kanban system in the beginning of the 90 s. It were identified 18 adaptations in practice in São Paulo State, however only 5 were analysed in the case studies. Among the 18 adaptations, 7 follow the logic of the original system and 11 do not. Thereby, it was proposed a procedure to evaluate the use of the kanban system in that industrial companies by means of the original work characteristics, production environment conditions and advantages of the system. The five adaptations analysed in the case studies have, as the main change, the utilization of only one type of signal or card. It was also concluded, by the use of the procedure, that the companies that use adaptations of the kanban system miss (in larger or smaller degree, depending on the adaptation) the following advantages: efficient production control; facility of problem causes identification; decrease of work in process; decrease of the lead-times; decrease of the waste; empowerment; simplicity of the administration mechanisms and efficient information control.

Euglossine bees are important pollinators of many Neotropical plant species, particularly orchids which could present a species-specific bee-flower relationship, essential to the reproductive success of these plants. Orchids produce chemical compounds to attract males of Euglossine bees (the effective pollinators of the orchids), and these compounds were isolated and are being used to study the biology of the euglossine males. Allozymes markers, although their low polymorphism content, were widely applied in population analyses. In order to provide a powerful tool to be applied to nest and population genetics research, primers flanking microsatellite loci were developed for Eulaema nigrita and Euglossa cordata (13 loci each). The use of these markers in 483 euglossine males of Euglossa, Eufriesea, Eulaema and Exaerete species, sampled in several Brazilian biomes and areas, evidenced the presence of only two diploid males, one in Euglossa annectans and other in Euglossa mandibularis. These findings support the hypothesis that diploid males (usually unviable or sterile individuals) occur in low frequencies in Brazilian Euglossine bee populations, a fact that is according to previous studies using allozymes. The application of these markers to nest structure analyses revealed nest sharing among unrelated females of Eulaema nigrita (eight nests). For Euglossa cordata and Euglossa townsendi nests (11 and seven nests, respectively), analysis demonstrated that monogamy (one female mated with a single male) is the rule, although nest sharing among unrelated females could also occur in E. townsendi. These results give a new focus on the research about population genetics and nest sociogenetic structure of Euglossine bees, opening new insights on the Euglossini biology and genetics.

A series of methods and techniques has gained prominence in the organizations that possess a standard of system for development of products - SDP in the conceptual phase of the project, as well as in redesign when necessary. The QFD, the Analysis of Kano and the Pugh Matrix are some examples of methods and used techniques to integrate methods in project. However, if one of the characteristics of methodology DFA is to reduce the number of assembly operations reducing the number of components and make the assembly operations easier to perform, this methodology can be applied in ergonomics, since it assists the design activity of work situations, specially in the stage of generation of alternatives and analysis of feasibilities for the simplification of the structure of the product. This way, the main contribution of this research is to demonstrate that the use of the Design for Assembly tool can be extended in situations of redesign of products for attainment of technical solutions in the situations of ergonomic interventions, or even though in the conceptual phase of a new project, where the ergonomics will be considered inside of vision DFA. The accomplishment of the Workplace Ergonomic Analysis - WEA associated with the use of the design for assembly - DFA tool for technical solutions in ergonomic interventions can be a possibility for design teams that are looking for associate design and ergonomics.

Common sense and learning. How can this kind of knowledge, which refers to the knowledge shared by the majority of people who are inserted into the same social and cultural context, support teachers to plan learning activities which fit to pedagogical issues, important to an effective learning? How can computational technologies make viable the use of this kind of knowledge by teachers, supporting them to make decisions during the planning of tasks of a specific learning activity? This research answers these questions (i) evaluating how common sense knowledge is related to Learning Theories, proposed by Paulo Freire, Célestin Freinet, David Ausubel and Robert Gagné, authors who are renowned in the pedagogical area; (ii) exploring how computational technologies can be used to collect and present this kind of knowledge to teachers; (iii) suggesting ways to teachers use it, in order to reach pedagogical issues; and (iv) showing the use of a framework to plan learning activity, considering the suggestions of using common sense to plan learning activities, made in this research. The suggestions can be summarized in supporting teachers: (a) to decide the detail level of the learning activity topics, based on the knowledge that the target group demonstrates to have well formalized, as well as on the misunderstandings that it makes about other topics, and on the information that it forgets to mention in the knowledge base; (b) to identify topics of general interest to be taught; (c) to identify a common vocabulary used by the target group; and (d) to support the use of cognitive operators. For this purpose, it is used computational resources, developed in the context of Artificial Intelligence researches, to plan a learning activity in the in the health domain, specifically in the domain of home caring a sick person. Teachers from the Nursing Department of the Federal University of São Carlos use these resources to plan a learning activity, taking into account the common sense knowledge acquired from the Brazilian population, stored in the knowledge base of the Brazilian Open Mind Common Sense Project, developed by the Advanced Interaction Laboratory from the Computer Department of the same University in partnership with the Media Laboratory of the Massachusetts Institute of Technology. The learning activity main goal is to prepare Nursing learners to interact with the population, from which the knowledge was acquired, orienting people from that population about the procedures that might be taken, in order to home care a sick person. The results obtained are critically analyzed and they point to the validity of the suggestions of using common sense to plan learning activities made in this research

Methyl parathion (MP) is an organophosphorus insecticide used worldwide in agriculture and aquaculture due to its high activity against a broad spectrum of insect pests. In a first phase of the study, specimens of matrinxã (Brycon cephalus) were exposed to a sublethal concentration (2 mg.L-1, 1/3 of the 96h-LC50) of MP (Folisuper 600®, MP 600 g.L-1) for 96h, and their heart rate (fH), oxygen consumption ( 2 O V& ), gill ventilation ( G V& ), and oxygen extraction (EO2) were measured, during normoxia and in response to graded hypoxia. The fish developed a significant bradycardia during moderate hypoxia, which was higher for the MP exposed group. 2 O V& was kept constant over a wide range of O2 tensions of inspired water (PiO2), until he critical oxygen tensions (PcO2), 35 mmHg for control group and 52 mmHg for the MP exposed group, respectively, were achieved. G V& increased following the changes in 2 O V& and was the result of an accentuated increase in breath volume, rather than in breath frequency. Oxygen extraction was kept almost constant at about 56% for both experimental groups, regardless of ambient oxygen tensions or MP exposure. We used an isometric muscle preparation to test the effect of a single 96h MP exposure to 2 mg.L-1 of MP on the heart excitation-contraction coupling of B. cephalus. Ryanodine (a blocker of sarcoplasmic reticulum Ca2+ release) reduced the force of contraction by approximately 70% in B. cephalus ventricle, suggesting that this species utilizes the intracellular Ca2+ storages of the sarcoplasmic reticulum (SR) during routine contractions. MP exposure resulted in a significant decrease in force development and an increase in the time to half relaxation (THR), providing evidences of the effect of MP on intracellular Ca2+ stores. Cardio-respiratory responses to MP can be attributed to damage caused to the gill epithelium, which results in impaired gas exchange. Effects of MP exposure to the ventricular myocardium correspond to the SR Ca2+ storages impairment and to cholinesterase inhibition in nerves supplying the heart.

The present thesis of Doctoral study is the resulted of research under the Post Graduation Programme of Ecology and Natural Resources of the Federal University of São Carlos (UFSCar) titling Constructing Educative Ways for Interpretation of the Pantanal s Environment . It reflects the research carried out about a pedagogical filter of the environmental education, with images of the Pantanal s ecology to interpret natural and cultural dimensions in two communities: Mimoso, São Pedro de Joselândia and other places located in the municipalities of Santo Antonio of the Leverger, Poconé and Barão de Melgaço, in Mato Grosso Sate, where we face many sort of environmental impacts and problems to protect the large wetland, in its broad meaning of nature and society. The presented results represent an effort of Environmental Education Group Researcher (GPEA) of Federal University of Mato Grosso (UFMT), which is built by many researchers from multidisciplinary approaches for understanding the ecological and cultural diversities of these two communities. The results reveal the fragile meaning of sustainable development, since we realised it is far from its implementation, especially that related to education dimension which claims for sustainable societies. The studies reflect new image s ways (photos), considering the aesthetic sensitivity as an important tool to promote a responsible and ethical look for the environment. The image s discourse of the investigated groups discloses lack of critical awareness in relation to the linked dimensions between human being, society and nature. In a similar way, it is observed that aesthetic of the image s discourse is suffering by lack of care in terms of ethical; poetical; management or policy to built the concept of development and its sustainability. The research was conducted by environmental education principles, considering the ethno knowledge of Pantanal s communities, for interpreting and perceiving the ecological space and social dimension of the wetland of their habitants

In this present work, we have carried out some calculations of electron-radicals scattering cross sections in the lowjintermediate energy range. Differential, integral, momentum transfer, total and total of absorption cross sections were calculated for the electron-SiF j SiF2 scattering in the energy range between 1,0-1000 eV. The dynamics of electron-molecule interaction is described by a complex optical potential formed by static, exchange, correlation-polarization and absorption contributions. The Schwinger variational iterative method combined with distorted-wave approximation is applied to calculate the scattering amplitudes. Some of the results presented here are compareci with the experimental andj or theoretical results available in the literature.

Osteoporosis is attributed to an imbalance between bone formation and resorption, followed by bone mass loss and microarchitectural deterioration, leading to increased bone fragility and fracture risk. Nitric oxide (NO) is a signaling molecule with important regulatory effects on bone cell function. Nitric oxide donor nitroglycerin has been reported to alleviate ovariectomy-induced and corticosteroid-induced bone loss. The aim of the present study was to investigate the effect of NO on cancellous and cortical bone of orchiectomized rats. A total of 98 male Wistar rats (four months old) were randomly divided in the following groups - Experiment I: intact treated with saline (stomacal gavage - gv), orchiectomized treated with saline (gv), and orchiectomized treated with NO donor isosorbide dinitrate - ISDN (gv); Experiment II: intact treated with saline (subcutaneous injection - sc), orchiectomized treated with saline (sc), and orchiectomized treated with NO synthase inhibitor NG-nitro-L-arginine-methylester - L-NAME (sc); Experiment III: intact treated with saline (intraperitoneous injection - ip), orchiectomized treated with saline (ip), and orchiectomized treated with NO precursor L-arginine (ip); Basal group: one group was killed at the beginning of the study (four months old) and served as a baseline group. The animals were killed after 8 weeks of treatment. At death, both femurs and lumbar vertebrae (L5-6) were obtained from each rat, and changes in both cancellous and cortical bone mass and biomechanical competence were assessed. The treatment with NO donor isosorbide dinitrate protected the cortical bone mass of adult rats from the deleterious effects of castration. The protective effect of ISDN treatment on the cancellous bone mass was not as significant as the one observed on the cortical bone. The L-NAME treatment did not increase the deleterious effects induced by orchiectomy in both cancellous and cortical bone mass. No effect was observed with the L-arginine treatment, in the dose used in this study. In conclusion, this study suggest that NO donor isosorbide dinitrate can be used in the future as an alternative pharmacological strategy for the prevention of androgen deficiency osteoporosis, in men with proven hypogonadism and in eugonadal men.

Este trabalho discute o papel do coordenador pedagógico no cotidiano escolar frente a formação continuada de professores. A importância e atualidade deste estudo na universidade, bem como no seio da escola de educação básica, local do exercício de liderança deste profissional, certamente se mostram pontuais na organização e desdobramento das atribuições do coordenador em relação ao seu papel, em relação ao seu compromisso teórico metodológico, ao estabelecimento de um clima organizacional propício ao desenvolvimento de um trabalho pedagógico que respeite as distintas vozes que se apresentam no âmbito escolar. Por meio de uma revisão de literatura, de discussões e análise de vivências no cotidiano da escola, selecionamos alguns pontos recorrentes para a discussão do objeto de estudo, o que nos possibilitou a constatar que a prática pedagógica se constrói pela contribuição de todos os atores sociais, cujo sujeito facilitador, pode ser materializado, dentre outros, na figura do coordenador pedagógico.

This work was carried out in three different areas of Universidade Federal de São Carlos. We studied the Geometridae associated to Rapanea umbellata (Mart.) Mez, 1902 (Myrsinaceae). The samples were collected at each two weeks, during the period of October of 2005 to april of 2007. It was used the method of entomological umbrella. The larvae were grown in the laboratory, using the host plant as food. Rapanea umbellata had the first register as plant hostess of Geometridae in the present study. It occured 14 species of Geometridae arranged in 11 genus, seven genus of Hymenoptera Parasitica and one Diptera. The common species that occured was Phrygionis polita (Cramer, 1780), whose relative abundance was 48,9%. Other Geometridae recordered were: P. paradoxata (Guenée, [1858]), Argyrotome melae (Druce, 1892), Opisthoxia sp. Hübner, [1825], Pero refellaria (Guenée, [1858]), Glena bipennaria (Guenée, [1858]), G. unipennaria (Guenée, [1858]), Hymenomima amberia (Schaus, 1901), Iridopsis chalcea (Obertür, 1883), Ischnopteris miseliata (Guenée, [1858]), Patalene Herrich-Schäffer, [1854], Oxydia apidania (Cramer, [1779]), O. vesulia (Cramer, [1779]), Prochoerodes tetragonata (Guenée, [1958]). The Hymenoptera parasitoids were: Euplectrus Nestwood, 1832 (Eulophidae), Charops Homgren, 1859 (Ichneumonidae), Hyposoter Foerster, 1869 (Ichneumonidae), Mesochorus Gravenhorst, 1829 (Ichneumonidae), Diolcogaster Asmed, 1900 (Braconidae), Hymenochaonia Dalla Torre, 1898 (Braconidae), Glyptapanteles Ashmed, 1905 (Braconidae). The density of larvae shows two peaks, one at the dry season and one at the raining season. In the same time occurs the smaller percentage of parasitism. The cycle of development of Phrygionis polita was studied, being the first description of the immature stages of a species of the Palyadini tribe.
