    The Sensory Processing Disorder (SPD) can cause difficulties on scholar performance and behavior problems in this context, what may interfere, thus, on the full participation of the student. The teachers are on a ideal position for the recognizing of de disorder signs and can change the life of a lot of children, because the SPD are unkown in Brazil and doesn t find the diagnosis, those children must be helping the improve of the school failure statistics. On the international tendencies for the concept of inclusive education, the prepared teacher for the inclusion is that one capacitated for different pedagogic strategies, for different students. The further teacher development has been considered one of the better ways for prepare the teacher for the inclusion. The aim of this research was to evaluate the results (short and long-term) of a further teacher development intervention about the SPD and its consequences for the scholar performance. The method was exploratory-descriptive s qualitative and quantitative. The research received authorization of the Municipal Education Secretary, was approved by CEP and authorized by the school after the teacher approval. The data collection and intervention was developed in a classroom of the participant school, located on a peripheral region of a midsize city of São Paulo s State central region. The research steps where developed during six HTPC s moments (a time for pedagogic collective work) and the participants where 16 teachers and administrators responsible for the first to the fifth grade from a government college of elementary education. A pilot study previously developed with two volunteers embased the elaboration and adequation of the data collection instruments and the illustrative cases, which were used as a base for complete the instruments. For the initial collect, participants filled the self-guided interview and the pre-test sheet. After the intervention, they filled the course evaluation and the pos-test. Eight months later, it was developed the follow-up data collecttion individual for those whom cited current students with similar profiles to the illustrative cases and a general instrument for all the participants. The qualitative data analysis where realized by theoretical axis, the quantitative data where analised using the t-student test, adopting p<0,05. The results shown the effectiveness of intervention to form opinion about new and unknown topics, once it was a movement from the non-responded affirmatives to the ones correctly responded on the pos-test. However, the intervention wasn t able to modifies pre-established incorrect concepts from the initial data collection. The follow-up showed that, for the topic discussed on this constructed intervention, this kind of further development wasn t able to transform participants in prevention e action agents. That means that the further development of this research got positive short-term results, but not long-term outcome in respect to the changing attitude.

    The Neonatal ICUs are designed for newborns at high risk, as in the case of premature infants.The environment in the NICU is a protective factor for life, but may prove to be inappropriate for the neurological development of preterm, specifically in relation to visual aspects. The aim of this study was to develop and propose a protocol for evaluating the context of the NICU, as a checklist to identify the risk and protective factors visual development of premature infants. Moreover , had the following specific objectives : Map and describe the national and international scientific literature on the Neonatal Intensive Care Units in respect of related visual development of premature variables ; Identify the risk factors and protection to the visual development of premature newborns present in neonatal intensive care units , expressed in the literature. The methodology was based on bibliometric analysis of papers retrieved on the basis of national and international data: VHL, ScienceDirect and Scopus. Bibliometric indicators analyzed under the classification into two categories were produced: Category 1 - Primary Issue (TP) and Category 2 - Issue Secondary (TS). Since the focus of this study lies in the studies classified into Primary Issue , were analyzed and categorized into the following themes : " Retinopathy of Prematurity Risk Factors , Incidence, Prevalence , Screening and Prevention " , " Retinopathy of Prematurity Treatment " , " Normal Development " , " Retinopathy of Prematurity Instrument " , " Environment and Retinopathy of Prematurity " Retinopathy of Prematurity Theory " . These studies the risk factors and protection to the visual development of preterm infants were identified. These factors allowed the construction of check list (initially with partial version and then the final version ). As most of the studies ( 97.7 % ) address on the Retinopathy of Prematurity (ROP) , the instrument will help identify risk and protective for the development of ROP in premature infants in the NICU context factors . It is intended in the future instruments available to professionals in neonatal ICUs, thereby preventing ROP in premature and thereby reduce the incidence and progression of disease.

    A server cluster connected to the Internet can support virtual desktops in a virtual computing environment. Each user can have his/her own virtual desktop, accessed through the Internet by means of devices such as laptop, PC, notebook, tablet or smartphone. The benefits of desktop virtualization include the possibility of improving utilization of computational resources such as processor, memory, disk and network; a more efficient management; centralized backup, and remote accessibility independently on the user location. Education institutions have traditionally used local desktops for use of faculty, administrative and technical staffs, as well as for their students. Managing these desktops requires a technical staff to take care of installation, configuration, updating and maintaining in a personalized manner, according to each user profile. In this manner, administration is costly and inefficient. Several companies increasingly adopted virtual desktops delivered by an infrastructure of centralized servers, while education institutions are late in this process. The diversity of applications used by different areas of teaching create demand for studies to better understand the performance of virtual desktop infrastructure. The purpose of this study is to evaluate virtual desktop infrastructure from the perspective of user quality of experience. To accomplish this, a virtual desktop infrastructure have been deployed at UFSCAR, and a set of experiments were carried out at our labs employing five different applications. To evaluate the influence of the networking quality of service on the user experience, we produced 5 scenarios with different communication latencies. Finally, we also executed experiments to evaluate the demand for computational resources (e.g., processor, memory, I/O, and network) as more virtual desktops are spawned. This experiment can provide important information for future capacity planning.

    Breastfeeding offers many benefits for mother, baby and Family. Its influence on child and women s health has been the focus of governmental campaigns and programs on national and global scale. The Brazilian Public Health Care System (SUS) develops initiatives to promote, protect and support Breastfeeding on health services. On primary health care, the Family Health Strategy Program has expanded the access to health care and to Breastfeeding initiatives. Health Care Networks were created to promote full care to patients. In São Paulo state, 17 Regional Health Care s Networks were implemented, organized and systematized starting from Primary Health Care Program. São Carlos city belongs to Regional Health Care s Network of number 13. The Primary Health Care Program acts as coordinator assuring full care s implementation on Regional Health Care Networks. Brazil has already programs to support Breastfeeding, but prevalence rates are below World Health Organization s expectation. Breastfeeding s success goes beyond health practitioner s individual performance. Among others aspects, there is also the responsibility of the Brazilian Public Health Care Manager, his initiatives and services on proposing, executing and following the strategies aimed to Breastfeeding. Starting from the assumptions that PHCP is the coordinator of network full care, that care and management are connected on FHSP performance and that higher education s professional teams of São Carlos USF (S) are responsible for create and manage Breastfeeding s care; this study proposes to analyze Breastfeeding s promotion, protection and support on PHCP according to the USF of São Carlos management team. It is a qualitative exploratory research where group interviews were used as data collection. The individuals were nurses, doctors and dentists responsible for executing and managing PHCP's strategies and policies. The data analysis was executed through ALCESTE software. Two thematic blocks were created: Aspects that hamper Breastfeeding , which includes the first class Early weaning's determinants and "Aspects that potentiate Breastfeeding divided in two classes: Aid and network's support to Breastfeeding and The management of Breastfeeding's care . It was evident that, even if the teams have reported the development of actions and orientations for mothers and families about Breastfeeding's practice, they have also evidenced certain impotence and frustration in front of mother's non compliance. They recognized the importance of the articulation with other health sectors, the relevance of professional updates and team meetings on care production and management. It is relevant that Breastfeeding s promotion, protection and support need to be intersectional in order to promote more resolute, humanized and full care.

    Brazil is a major exporter of oranges in the world, with the state of São Paulo, the largest citrus producer in the country. In the last years plants of the genus citrus have been strongly affected by various diseases and among them, the disease Huanglongbing (HLB) have occupied prominent role and importance due to the devastating damage caused to citrus production worldwide. Caused by Candidatus Liberibacter spp., a bacterium that colonizes and blocks the conductive vessels of elaborated sap (phloem) and transmitted by the vector, hemiptera, the psyllid Diaphorina citri. In this context, it is necessary to search for strategies to control the disease in citrus orchards. In order to identify a cysteine peptidase D. citri, in this work, the identification, recombinant expression and characterization of a cysteine peptidase D. citri, the type (cathepsin B) called DiaciCATHB was performed. The identification of an ORF for cysteine peptidase was performed using the database of the transcriptome of D. citri. Recombinant expression was performed in Pichia pastoris yeast cells. For activation of the recombinant enzyme important factors were observed, acidic conditions and incubation in suitable temperature and time. Kinetic characterization of the enzyme was verified by hydrolysis of the synthetic substrate Z-Phe-Arg-MCA, resulting in a (km) of 15.7 mM. Inhibition of the enzymatic activity tests were conducted using the recombinant inhibitor of cysteine peptidases CaneCPI-4, resulting in the inhibition constant (Ki) of 0.05 nM. The analysis of gene expression DiaciCATHB demonstrated that gene expression occurs in all stages of insect development, there is however a significant difference in expression level. According to the developmental stages of the insect D. citri, the expression level gradually increases DiaciCATHB, being higher in nymph and adult stages. The present results do not prove that the location and function performed by the enzyme DiaciCATHB, but regardless, the cysteine peptidase in this study has the potential to become an important target for use in future studies on insect control.

    Result of a field work among the Awá-Guajá, a Tupi-Guarani speaking people of Eastern Amazon, this dissertation focuses on the various relations of alterity that are currently being lived and experienced with the many powers that act directly and indirectly in Awá life. Are these Others, now approaching or distancing, but always present in some way, whether in speech, in memory or in action. The transformation is constant and the present study attempts to explore some of these developments whose dialogues, multiplied as they are, become essential for us to think about the Awá-Guajá politics. To this end, I go through certain paths that lead us to these agents full of enemies and/or affines: karaí (non-Indians), kamará (other Indians), awá ka a pahara (other Awá) and karawara (celestial beings). Sometimes ambiguous, these Others give the tonality of a "new indigenous politics whose contours never cease to be problematized.

    The participation of occupational therapists in inclusive education has been constituted as a field in progress in the country with intervention not only focused in the student, but extended to the school, teachers, classmates and family. The records of these interventions are as important as understanding the practices developed, since this procedure is a fundamental part of the work. Considering that there is no standard methods to document the services of occupational therapy, it is necessary to pay attention to the fact that regardless of the method, the action of the record comes from the need to have information deriving from the assistance as a way of orientation and follow up inspection over the service provided and about the technical responsibility adopted, and being also a supplier source for research data. Glimpsing the importance of documentation, this study was aimed to identify, according to the opinion of the occupational therapists in the state of São Paulo who work in inclusive education, how the records of their interventional practices are performed. Methodologically a questionnaire was provided in a specific web site during a predetermined period and the obtained data were analyzed using descriptive statistics. The participants were 55 occupational therapists who work in the process of inclusive education and registered in the 3rd Region of the Regional Council of Physical Therapy and Occupational Therapy. The results show that the free narrative style can be considered the most used model in registering information, with responses (35.7 %) affirming that there is not the practice of recording all interventions. The lack of availability of time for the records within the routine work was also indicated by 60.7 % of the participants. Over half of the interviewed mentioned that the school institution had received some form of intervention from another occupational therapist, where 80.6% of the cases have documentation about this work, and 48 % of these notes were indicated by participants as not containing sufficient information to understanding and continuance. It is believed that this study allowed views of praxis, signaling new points to be investigated, which consequently, could contribute to improvements in the quality of records and also in the improvement of the profession.

    In Brazil, the Mental and Behavioral Disorder ranks third in number of sickness benefits provided by the National Institute of Social Security (INSS) and thus illustrate the importance of further research on the topic. The aim of this study was to know the process of return to work of municipal workers who were turned away by mental and behavioral disorders, received sickness benefit (for incapacity) and returned to work activities. Participants were seven employees of a Municipality in the State of Sao Paulo, who managed to return to work activities after being away from work for 30 days or more with a primary diagnosis of Mental and Behavioral Disorders (CID F from CID-10) in the period January 2008 to December 2012. Data collection happened in the period December 2012 to March 2013 and it accomplished through filling out a personal information and professional protocol related to the removal process and return to work and the application of a semi-structured interview which addressed questions about the process of removal and return to work. For data analysis, the technique used was Thematic Analysis. The results showed that the participants were unanimous in considering their families as the main source of support in the process of return to work activities. Regarding the reasons that led to the illness and consequent removal from work, some participants reported poor relationship with superiors and coworkers. Nevertheless, a good relationship with management and co-workers appeared to aid in the process of returning to work. The physical environment, inadequate and precarious working conditions were identified as facilitators for mental illness in workers. Participants signaled suggestions about changes in their work environments, which could make them less sick prone, and more appropriate and favorable for good employee performance. For most of the study participants there is no difference in the meaning of work in their lives prior to removal and after returning to work. The work takes on different meanings in the lives of the participants related to personal fulfillment and enjoyment, social function, means of support and space for socializing. Although all participants had undergone expert care of the INSS, none received any information or indication on the Vocational Rehabilitation Program of the INSS. It is expected that this research will contribute to the strengthening of the local network of health care worker and bring enlightenment about reinsertion of these people into the labor market and the assurance of their rights.

    Learning to read is preceded by the acquisition of vocabulary, and premature birth is a risk factor for the delayed development of language. However, few studies have investigated the association between prematurity and delays in expanding vocabulary and learning to read and write. The present study was conducted with 20 students, aged 5 years 8 months to 6 years 6 months, 10 of whom were born late preterm and 10 were born full term. Their receptive and expressive vocabulary was initially assessed. A computerized program was then implemented to expand vocabulary and teach reading and writing. The late preterm students average gestational age was 35 weeks, and their average birth weight was 2,450 g. The full term students gestational age was 39 weeks, and their average birth weight was 3,146 g. The predominant classification of nutritional status among the students was appropriate for their gestational age and weight. The results showed similar performance between late preterm students and full term students in receptive skills, such as expressive vocabulary, which was lower than expected for their ages. In expansive vocabulary, all of the students achieved 100% accuracy in the selection of figures. In the picture-naming task, late learners who were born preterm had higher scores than those born full term (93% vs. 76%). None of the students read or wrote (dictation) any of the words presented in the pretest. In the post-test, we found the partial emergence of reading and speaking repertoires among the students. The two groups read 50% and 40% of the words correctly and wrote 29% and 12% of the words correctly, respectively. Therefore, the performance of late preterm students was higher compared with full term students in both reading and writing. Prematurity is a multifactorial event, and other factors may have potentially interfered with linguistic development in these children. Regardless of the condition of their birth, all of the students scored below the expected range for typical development in word recognition and naming. The correlation that was observed in the post-test confirmed the predictive relationship described in the literature between receptive vocabulary and reading acquisition in late preterm and full term infants and expressive vocabulary acquisition and writing in late preterm infants. Differences were found between oral reading among late preterm students and receptive reading (or recognition) among full term students. Similar to writing, speaking was correlated with expressive vocabulary only among late preterm students. These results strongly suggest the need to implement and maintain literacy interventions in the study participants using different classes of verbal operants that feature oral language.

    Starting from works by Scherk (1835) and by Enneper-Weierstraß (1863), new minimal surfaces with Scherk ends were found only in 1988 by Karcher (see [16, 17]). In the singly periodic case, Karcher s examples of positive genera had been unique until Traizet obtained new ones in 1996 (see [41]). However, Traizet s construction is implicit and excludes towers, namely the desingularisation of more than two concurrent planes. Then, new explicit towers were found only in 2006 by Martin and Ramos Batista (see [24]), all of them with genus one. For genus two, the first such towers were constructed in 2010 (see [40]). Back to 2009, implicit towers of arbitrary genera were found in [11]. In our present work we obtain explicit minimal Scherk saddle towers, for any given genus 2k, k ≥ 3, that we denote ST2k. We also present the MATLAB and Evolver programming that make it possible to generate the surfaces ST2k. MATLAB is an abbreviation forMatrix Laboratory, a program developed and distributed by MathWorks. Evolver is a free iterative program developed by Kenneth A. Brakke, a professor at Susquehanna University (see [3, 34]).

    The objective of this thesis was to analyze changes in the graduate level program of education at the Federal University of Minas Gerais (UFMG) Brazil, between 2000 and 2010 after Brazil adopted a new model of economic development, characterized by financial dominance accumulation which has served to position Brazil in the globalized economy. The time frame analyzed in this thesis was a milestone period for the Brazilian public university system at large and UFMG, especially at the graduate level. Changes in graduate education programs which occurred during this period played a strategic role in establishing a platform for financial capital accumulation and economic development within Brazil. This movement of graduate education program development led to the implementation by Brazil of a set of State initiated public policies that caused science, technology and innovation research to become a high priority focus within the public university system of Brazil. This served to create a central and highly relevant obligation imposing new demands on the Brazilian public university with regard to graduate level education programs serving as the locus for knowledge production at Brazilian higher education public institutions. This positioned the Brazilian public higher education system as a significant public policy instrument toward meeting increasing demands of the private sector of Brazil for science, technology and innovation development. This study undertook to demonstrate how the macroeconomic policies implemented during the period of study produced consequences in higher education, more specifically, at the graduate level. This was accomplished by analyzing the case of the Federal University of Minas Gerais (UFMG). The data obtained for this study allowed for observation of a remarkable expansion of graduate level education during the analyzed period, brought about as a result of the public policy for higher education to focus on science, technology and innovation, with the goal to consolidate the National Innovation System in Brazil. The conditions discussed and analyzed in this study reveal the existence of a graduate system of education that has been reformulated as a result of governmental policy to increase the number of researchers in strategic areas in accordance with the Industrial and Science, Technology and Innovation policies of Brazil, reflecting the economic demands of the industrial and financial sectors of the country.The economic realignment produced during the analyzed period generated consequences for higher education within Brazil causing significant changes in the organization and functioning of the public university system of Brazil, especially at the graduate education level. These changes brought about commercialization of academic research and an orientation toward academic productivity for the benefit of the Brazilian economy. This also resulted in a culture change within Brazilian public institutions of higher education with regard to scientific production.

    New alternatives to the use of polymeric membranes as solid electrolyte in fuel cells have been considered , in order to find solutions to recurrent obstacles that limit the performance of these cells, the dependence of the ionic transport due to the water content of the membrane and low thermal stability of the current polymers used . In this investigation, we sought an alternative, by studying the incorporation of imidazolium salts into polycarbonate (PC) matrix and the subsequent formation of membranes via casting. Characterizations that aimed to establish structure-property correlations by FTIR, DSC, TGA, DMTA, Water Vapor Permeation (WVT), Sorption and Desorption and Methanol Permeation were performed. The results indicated that the presence of different ionic liquids (IL) into the PC matrix significantly alter the structural and membrane transport characteristics analyzed.

    The increasing demand for it in today s world and the problems caused by fossil fuel usage lead to a search for alternative sources that may integrate the world s energy matrix. In this context, because this product is essential to technological, social and environmental development of a country, biofuels like ethanol and biodiesel are strong candidates to minimize the worries about energy availability. Biodiesel is often produced by transesterification reaction using homogeneous catalyst as sodium hydroxide (NaOH) or potassium hydroxide (KOH). However, these materials present issues like the soap formation and need for additional steps in the process to neutralize and purify the product in order to be under specification of Brazilian National Agency of Petroleum, Natural Gas and Biofuels. This fact has stimulated research to find new materials to replace the current route of biofuels production and one promising material is the heterogeneous catalyst. With this motivation, this work presents a new alternative to the synthesis of a solid recently classified as heterogeneous catalyst, the MCM-41, aiming the minimization of costs for its production. The material was synthesized using sodium trisilicate as silica source and it was later tested, without modification, in transesterification reaction between an ester and an alcohol. The results showed catalyst activity and the conversion was around 40%, but its reuse reveals intense loss of activity because of CTA+ cations removal. However, new techniques are under development to guarantee more stability to the catalyst.

    To prevent and treat pelvic floor muscle (PFM) dysfunctions, level A of evidence proposes isometric contractions to strengthen these muscles. In literature, there are studies regarding the cardiovascular effects of isometric exercises and the cardiac autonomic regulation in response to these exercises. However, currently there are no studies regarding the cardiovascular response to PFM exercises and the effects of these responses to sympathetic and parasympathetic cardiac modulations. Therefore, the objective of this dissertation was to analyze heart rate (HR) response to a protocol of PFM contractions and the acute effect of the PFM contractions in blood pressure (BP) and sympathetic and parasympathetic cardiac modulations responses and compare these variables to rest conditions before and after the PFM contractions. We evaluated eutrophic women aged between 18 and 80 years, divided in groups according to age. They underwent two protocols; each one containing a series of PFM contractions with monitoring of the PFM contraction pressure, HR, BP and R-R intervals. Both series contained 10 PFM contractions, one series contained contractions lasting 5 seconds with 5 seconds of rest between each contraction and the other series contained contractions lasting 10 seconds with 10 seconds of rest between each contraction. We observed an increase in HR during PFM contractions and an increase in systolic BP immediately after the contractions in the evaluated groups. Regarding the cardiac autonomic regulation, we performed the time domain (RMSSD and SDNN indexes) and frequency domain (low and high frequency spectral components in absolute values) analysis. We observed increase in SDNN and RMSSD indexes during PFM contractions; after frequency domain analysis we observed predominance of vagal modulation in the group containing young women after the series of PFM contractions with 10 seconds and the group consisting of adult and elderly women showed a higher prevalence of sympathetic modulation after series of PFM contraction lasting 5 seconds. The observed variables were within the normal values and returned to basal values as soon as the contractions ended. In conclusion, the proposed protocol of PFM contractions might not represent a cardiovascular risk for healthy women. Moreover, the applied protocol did not changed positively or negatively the cardiac autonomic modulation.

    In this research, entitled Dialogues and tensions: the perception of black and white teachers about the formation of black identity in the school context, we seek to understand, from the dialogue between black and white teachers, what knowledge can be identified and created for ways to strengthen the identity of black children in schools? Ergo, the following objectives are delineated: to discuss and reach consensus with teachers about a concept of identity for promoting the positive development of black identity; and with the teachers, analyze the practices, materials and/or training courses that can strengthen the identity of black children; also, suggest and elaborate practices that strengthen black identity, and point out ways to promote the education of racial and ethnic relations. The research objectives were achieved based on a theoretical study, followed by a field study. The former included readings about the education of racial and ethnic relations; the concepts of identity, diversity and respect for differences; equality of differences and their relation to a dialogic approach and anti-racist education. To understand the concept of identity, the main references used were: Giddens; Gomes; Munanga and Castells; and the relationship between black identity and school was based on the theorists of sociology, anthropology and education. Our investigations were also based on researchers from the Centre of Research on Theories and Practices for Overcoming Inequalities (CREA) and the Center of Research on Social and Education Action (NIASE), which help in the understanding of a dialogical education and equality of differences. To investigate what has been produced in Brazil about this theme, a production review was conducted in SciELO, as well as in some WG of ANPED. The field study was characterized by monitoring discussion groups comprised of six elementary school teachers (4 black and 2 white teachers), which developed dialogic practices in their classes. The research developed was based on the critical communicative methodology, which involves an intersubjective dialogue between participants and researcher, with the subjects critical self-reflection. There were 5 communicative groups, which enabled the participants to dialogue about topics previously agreed on regarding the research question. As for the results, we can state that it is possible to strengthen black identity by means of intentional teaching practices that are committed to and guided by knowledge. For this, one must resort to valuing ethnic and racial diversity, being open to dialogue and promoting actions to promote the equality of differences. From the discussion groups, we concluded that conceiving a positive black identity in the school context requires a black presence in the school, in other words, one must have the history, culture and black ancestry in the school environment and break the silence that still exists about being black. We also conclude that the practices to affirm black identity must be participatory, which means that in addition to narrating stories about Africa and black Brazilians and recounting these activities, it is fundamental having the presence of blacks, Africans and indigenous people in the school context, in order to help black and white children do away with the stereotypes inserted in our society. Another element to be highlighted in terms of teaching practices in the discussion of valuing diversity, regards teacher training courses; such courses are seen as indispensable for understanding the issue presented herein. Finally, we conclude that there is still much to be overcome when we deliberate on the equality of differences and Brazilian racism. Black identity exhibits an inner complexity that requires further studies by researchers and more sensitivity by the teachers. This issue does not end here, with questions that remain open for discussions in future studies.

    In this work flexure shear and tension shear are studied. It is presented a literature review with emphasis on the major normative recommendations about the shear strength in elements without shear reinforcement. Concerning flexure shear capacity considerations are made about the tensile strength of high strength concrete by analysis of 39 experiments. This samples were collected in the literature and are presented herein. Furthermore, it is proposed to consider the variable influence of prestressing on the shear strength. With respect to tension shear, it is proposed the coefficient b, which seeks to improve the traditional models considering indirectly the influence of shear stresses in transmission length. 49 international experiments are analyzed to validate this coefficient and it is concluded that the modified models show significant improvements. Yet developed an experimental program were tested 15 hollow core slabs varying the distance between the edge of the slab and its nearest support. All failures were by tension shear. The transmission length established by NBR14861 was considered adequate for the tested slabs by correlation with tension shear test results.

    In the latest decades, companies have faced important and increasing challenges set by globalization in product markets and production factors. This way, consumers become highly demanding and are always searching for new products, highly qualified, customized and quickly produced. Given these changes, the speed of delivery and therefore the efforts to reduce lead time emerges as one of the main objectives adopted by a company to compete in the market, since the strategies based in time aim to provide faster answers to its customers. In this context, the present paper aims to describe a proposal to reduce the lead time from the application of the concepts and methodology tools Quick Response Manufacturing (QRM) in a capital good sector s company. In order to achieve the proposed objective, a literature review about the QRM methodology and POLCA system and a case study in a company that develops and manufactures machinery and custom made equipment. Thus, it was analyzed the main causes of the waiting in the manufacturing of pressure vessels process, and through improvement proposals, it was achieved the results and gains expected. The main results, other than the 40% reduction in lead time, are related to quality improvement, increase of process responsibility in the manufacturing and simplifying the production control.

    Energy Efficiency and optimization of dryers are research areas with environmental concerns. These areas have the increasing need to improve the energy performance of processes through to quality improvement and reduction of production costs. In this sense, this work aims to contribute to the development of more efficient drying processes, take account the fact that this is one of the unit operations of higher energy consumption. Using a mathematical model for a direct-heating rotary dryer, computational simula¬tions were performed and the comparation with experimental results show that this model is reliable with the drying process. The model was implemented in order to simulate the rotary drier with concurrent and countercurrent feeding. Thus, the energetic differences between the two operations were compared and discussed. For the studies of the energy performance of rotary dryers, two definitions of Energy Efficiency were used: an expression quite common in the literature, and largely used in drying procedures, and another expression that was proposed from the observation of energetical quantities related to the process. The advantages and disadvantages of each defition are presented and the results contribute to the discussion on the assessment of Energy Efficiency in convective dryers. Parametric Sensitivity studies have quantified the influence that certain process va¬riables have on measures of Energy Efficiency and Final Moisture Content of Product. These results showed that these variables play an important role in both the Energy Ef¬ficiency and Final Moisture Content of Product, being necessary to establish appropriate operational limits to the range of variation to these variables, in order to satisfy the best operational conditions for the two rotary dryers. The results also showed significant dif¬ferences between concurrent and countercurrent operations. In addition, the Parametric Sensitivity analisys serve as a base for optimization studies. The results from the optimization of rotary dryers showed that is possible to im¬proving the Energy Efficiency without decrese the quality of the final product, and also the possibility of simultaneous improvement of both the Energy Efficiency as the Final Moisture Content of Product. It was possible to establish, for each dryer, mathematical relations between optimum Efficiency and desired Final Moisture Content of Product. These results are very interesting and represent an important contribution to the study of rotary dryers.

    The present dissertation is divided in 4 chapters. From chapter 1 to 2, we review some basic concepts of the normal Fermi liquid theory (a set of interacting fermions in correspondence with the Fermi gas) such as quasiparticles, some equilibrium properties, and we also derive the kinetic equation for spin waves in presence and in absence of an external magnetic field. The main purpose of this work is the study of the massive mode (which has a gap in the energy spectrum, ω(q=0)≠0) that exists in the liquid s isotropic ferromagnetic phase. The idea of chapter 3 is to review how the interaction between fermions leads to phase transitions in Landau Fermi liquid theory and also the concepts of broken symmetry and order parameter. Chapter 4 can be divided in three parts. In the first, we present the basis for ferromagnetic Fermi liquid theory (FFLT) and discuss how the phase transition from normal to ferromagnetic is accompanied by spontaneously broken symmetry, leading to propagating modes described by elementary excitations such as the Nambu-Goldstone mode and the massive mode. A second part, a review is taken in order to discuss the massive mode from "birth" to characterization as a massive mode like the Anderson-Higgs mode. Lastly, the third part presents the results obtained for the behavior of the massive mode in the presence of an external magnetic field. We compare the results obtained for the dynamic structure form factor with the ones obtained in previous works.

    The present study aimed to investigate aspects of the formation and action of teachers, working with pupils with special educational needs, in inclusive perspective, in multifunctional resource rooms, specifically in the city of Sorocaba- SP. The specific objectives included: the possibilities and challenges perceived by teachers working in SEM; investigation as to how the educators felt and acted in the face of difficulties encountered in educational practice; and evaluation, according to the existing continuing education, offered by the Department of Education through the Center for Excellence in Education - Don Jose Lambertt. Four teachers, working in multifunctional features, participated in this study. The procedures used were: semistructured interviews, participant observation, records from field diaries and document research. The results were analysed based on four axes: the profile of teachers of specialized educational services (AEE), subsequent to their initial training offered by Pedagogy courses; the challenges and possibilities facing teachers within Specialized Educational Services (ESA), in the Multi-Functional Room Appeal (SRM); the articulation between the meaning of skilled labor and teaching practices; and the perceptions of on-going education promoted by the Department of Education (SEDU) / Reference Center for Education (CRE). These axes have some major aspects, some of which have been highlighted: the importance of continuing education, according to the teachers interviewed; and the contribution and limitations of this proposal in terms of their teaching practices, in the use of multi-functional rooms. In conclusion, despite the weaknesses of continuing educational programs for teachers of SRMs, there have still been major advances and the participants themselves recognize how these formations can influence the way we act towards the obstacles encountered in the daily lives of SRMs.
