The physiology of mango is little known in relation to other fruit trees. There are gaps about estimation of mango leaf area using no destructive methods or concern photosynthetic responses under temperatures above 10oC, carbon assimilation, leaf and bud productions inr shade. The aims of present work were to shed light on these gaps determining on mango cultivars Tommy Atkins and Haden a) Indexes and equations for fast and no-destructive estimate leaf area (AF) just using length (C), maximum width (L), or both; b) Photosynthetic capacity, leaf and bud production growing under 0, 65 and 85% of shade and, c) The photosynthetic responses (photochemical and photosynthetic capacities) under temperatures between 17-32o C. The leaf area (AF) could be estimated multiplying length x width x 0,74 (for Tommy cultivar) or 0,78 (for Haden) as well using equations: AF = 4,96349 C - 33,429 (R2=0,86); AF = 17,02964 L - 18,88065 (R2=0,85) and AF = 0,73499 (CxL) + 0,59459 (R2=0,92) for Tommy or AF = 5,35282C - 33,17061(R2=0,88); AF = 19,09951L - 24,61777(R2=0,89) and AF = 0,76015(CxL) + 0,43257(R2=0,99) for Haden. In shade the cultivars presented same values of maximum net photosynthesis (Amax) obtained under full solar irradiance, decreasing the light compensation point and/or increasing the chlorophyll content. Besides, until 65% of shade, both cultivars maintained the same leaf and bud production in relation to full solar irradiance treatment, enabling them for plantation under high densities until middle shade intensities (around 65%). The optimum temperature range for Amax was 23-29oC in Tommy and 23-26oC in Haden. Both cultivars presented an unbalance between photochemical and biochemical phases of the photosynthesis in between 17-32o C, especially Haden. Under regular atmospheric concentration of CO2 the net photosynthesis of Haden, in general, was smaller than Tommy, while under CO2 saturation the opposite happened, possibly because Haden used its largest capacity of electron transport to increase the carbon assimilation, and, at the same time, decreasing its susceptibility to oxidative stress. Both cultivars presented high temperature adaptation maintaining almost constant the intensities of dark respiration (Rd) in Tommy and the photorespiration (Pr) in Haden. In Tommy Pr induced increases in light saturation (LS) and compensation (LCP) points, and reductions in apparent quantum yield (α). In Haden increases in Rd, LS stability and α reductions with temperature did not keep relationship with Pr nor with RE probably because the rupture of the cellular homeostasis caused by high electron excess.

Children, as well as women, the elderly and the disabled, are the preferential victims of violence. The child ca be a direct or indirect victim of such phenomenon (as in the case of children exposed to marital violence). Child maltreatment damages cognitive development and may be responsible for declines in academic performance. The aims of this study were: a) to characterize the school performance of victimized children referred to the Judicial System (Study 1), and b) to identify teachers and school principals views on domestic violence and inclusionary practices (Study 2). Twenty victimized children have participated in Study 1 (ten male and ten female), whose school performance were compared to their peers of the same classroon, gender, age, but without a history of family violence. Eighteen teachers and ten school principals participated of Study 2. Children from both groups were given three instruments: The Academic Performance Test, Parenting Styles Inventory and Raven s Progressive Matrices Test. The children gave samples of their notebook production. Children s mothers answered a family interview and the Revised Conflict Tactics Scales (CTS-2). Teachers and school principals also took part of an intervew. Teachers report cards were analyzed and teachers offered their impressions on student s academic performance. Results generally indicated inferior academic performance by the victimized children, when compared with their matched group, in spite of similar results in the Raven s Test for both groups. According to teachers, victimized children had inferior academic performance in relation to their non-victim peers, having in addition, more behavioral problems and aggressive behaviors. CTS-2 results indicated that most of the victimized chilren were exposed to marital violence; in most cases, the target of violence was the child s mother. The teachers and school principals demonstrated to have notions about domestic violence. In regards to school inclusion, their knowledge was found to be superficial. In addition, teachers showed some reservations about adopting inclusionary practices.

The technology of the DNA-Arrays is a tool used to identify and to compare levels of expression of a great number of genes or fragments of genes, in di¤erent conditions. With this comparison, it is possible to identify genes possibly causing illnesses of genetic origin (cancer for example). Great amounts of numerical data (related the measures of levels of expression of the genes) are generated and statistical methods are important for analysis of this data with objective to identify the genes that present evidences for di¤erent levels of expression. The objective of our research is to develop and to describe methods statistical, capable of identifing genes that present evidences for di¤erent levels of expression. We describe the test t, considered for Baldi and Long (2001) and consider three others methods. The first method considered is based on the use of parametric Bayes inference and the methods for selection of models, Bayes factor and DIC; the second method is based an semi-parametric bayesian inference, model of mixtures of Dirichlet processes. The third method is based on the use of a model with infinite mixtures of distributions that applied the analysis of the genica expression determines groups of similar levels of expression.

In this work, a nickel tube used as atomization cell and a ceramic capillary for thermospray generation (TS-FF-AAS) were employed to increase the analytical performance of the flame atomic absorption spectrometry (FAAS). The applicability of the method was evaluated for Co(II) and Cr(III) determination in food samples. Due to factors such as the low temperature into the atomization tube, the high atomization temperatures of the analytes, and the low levels of these elements in biological samples, a cloud point extraction (CPE) method was applied to both improve the processes of volatilization and atomization by formation of volatile metal complexes, and increase the sensitivity. Triton X-114 was used as surfactant to the implementation of the cloud point preconcentration procedure and, after the evaluation of several complexing agents, the best results were obtained with ammonium pyrrolidinedithiocarbamate (APDC). Parameters such as pH of complexation and concentrations of both surfactant and complexing agent were optimized. To improve the sensitivity, two configurations were evaluated to change the internal temperature of the atomization tube. The slotted tube, in which the internal temperature is higher due to more intense flame penetration, provided a significant increase in Cr(III) sensitivity. Parameters such as flame stoichiometry, atomization tube height, rich phase solvent, sample volume, carrier and flow rate were also evaluated. Limits of detection (LOD) of 2.1 and 2.5 µg L-1 and quantification (LOQ) of 7.0 and 8.4 µg L-1 (n = 10) for Co(II) and Cr(III), respectively, were obtained using optimized conditions. Intermediate precision (5.8 and 5.4 % for Co(II) and Cr(III), respectively), presented as relative standard deviation (RSD, %, 1s), were calculated from 10 consecutive readings of both analytes preconcentrated solutions. Interferences were observed in both volatilization and atomization processes into the atomization tube, as well as in the reactions of metal complexes formation due to both the complexity of the sample and the high concentrations of concomitants. A procedure based on extraction with 1 mol L-1 HCl was adopted for Co(II) determination. Only divalent species are quantitatively extracted. On the other hand, critical interferents, such as Fe(III) and Al(III), are not extracted. Procedures for interferents complexation with either fluorides or ethylenediaminetetraacetic acid (EDTA) were evaluated for Cr(III) determination. Method accuracy was checked by Co(II) determination in two certified reference materials (tomato leaves and bovine liver). There were no statistical differences between determined and certified values in a 95 % confidence level. The proposed method is efficient and allowed the determination of trace concentrations of Co(II) in foods without the need of sample digestion. However, the Cr(III) determination in foods was not possible due to the sample complexity and the interferences caused by concomitants in both preconcentration and determination steps.

The aim of the present study was to characterize the benthic community of Promissão, Nova Avanhandava and Três Irmãos reservoirs, in relation to the composition of taxa, population densities and also to verify the occurrence of exotics mollusks in this reservoir system. Moreover, it aimed to evaluate possible relations between the physical and chemical characteristics of the water and of the sediment and the structure of the community considering the spatial (upper, middle and lower portions of each reservoir) and temporal scales (dry and rainy periods). Sampling was carried out through November 2002 (rainy period) and August 2003 (dry period). Sediment samples for the analyses of the benthic community were obtained using a van Veen grab. The benthic communities of Promissão, Nova Avanhandava and Três Irmãos Reservoirs, were represented, in the rainy period, for a total of 24, 23 and 15 taxa, and in the dry period, for a total of 25, 25 and 17 taxa, respectively. In both sampling periods, and in all reservoirs, there were representatives of Phylum Arthropoda, Annelida, Mollusca and Platyhelminthes. Only in Nova Avanhandava Reservoir the occurrence of individuals belonging to the Phylum Crustacea were registered. The main groups in the benthic communities were Mollusca, Oligochaeta and Chironomidae. Amongst the Mollusca, three exotic species were found: Melanoides tuberculata, Corbicula fluminea and Helisoma sp. M. tuberculata was the most abundant species, corresponding to more than 60 % of the total individuals. C. fluminea and Helisoma sp were less abundant and they did not register in all the portions of the reservoirs. Among the representatives of the Oligochaeta, the species Branchiura sowerbyi was the most abundant and unique, occurring in all reservoirs and periods sampled, being registered with a maximum abundance of 6 %, during the rainy period in the upper portion of Promissão Reservoir. Chironomidae had the highest species richness, and Coelotanypus sp was the most abundant taxon, in all the reservoirs studied. The highest diversity of taxons was found in Promissão Reservoir. It is possible that eutrophication have favored the primary production, the survival and the establishment of certain species. The low values of uniformity found in all three reservoirs and in both periods of sampling reflects the presence of highly dominant species, as it is the case of M. tuberculata. The present study evidenced the high capacity of invasion of this species, which is widely distributed in all the reservoirs, evidencing the necessity of control or erradication of these exotic and invasive species in the reservoirs.

Traditional and recycled mortar and concrete have been produced and the results from simple compression strength and water absorption tests have been compared. Recycled mortar and concrete have been produced out of sludge from water treatment plants and rubble from construction and demolition. The amount of aluminum present in the leached extract from the solubilization process of the concrete produced with the addition of both sludge from water treatment plants and rubble from construction and demolition has been determined. In terms of simple compression strength, the addition of up to 4 % of sludge in mass in place of natural sand has made it possible to obtain recycled concrete with similar characteristics to traditional concrete. Although water absorption of concrete and mortar produced from both sludge from water treatment plants and rubble from construction and demolition is much higher than water absorption of traditional mortar and concrete, the results have not made it impossible to use them; it has just restricted their application to places free from moist resulting from weather conditions or use characteristics. The leached extract resulting from the solubilization of the concrete produced out of both sludge from water treatment plants and rubble from construction and demolition has shown aluminum concentration higher than the drinkability standard defined by the Brazilian standards agency (ABNT), but not in such a level to turn the rubble from the recycled product dangerous to human health.

The presence of a disabled child in a family affects not only the parents but also other members, mainly, the siblings. This members can be involved directly and indirectly with the care of the disabled brother or sister, and this population is at risk for behavioral and psychological adjustment problems. However, this field of research is narrow, mainly in Brazil. The way in which brothers and sisters react to the presence of a disabled child depends on several things, like social support available to the family and the age of the siblings. Most investigations in this field is interested in the psychological adjustment of brothers and sisters, and little attention is paid to the interaction between them and its relation with some aspects of the family and the siblings. Thus, the purpose of the present study was: 1. To describe the relationship in sibling s dyads, separated in two groups one with the mentally retarded sibling with age between 10 to 14 years old (Group 1), and another with the mentally retarded sibling with age between 21 to 24 years old (Group 2); 2. To compare the performance in the relationships of the both groups; and 3. To assess if there are differences in the relationships between the groups when the family social support and resources are considered. Two sessions of sibling s interactions in game situations (domino) and daily situations (listening to music) and one session of a sibling s daily activity were videotaped. The following instruments were used with the siblings: Formulário de Irmãos (Sibling s Questionnaire) and Interview with Siblings of Person with Disability. In terms of the caretakers the following scales were used: the Escala de Apoio da Família (Family Support Scale), the Escala de Recursos da Família ( Family Resources Scale) and the Escala de Apoio à Maternidade/Paternidade (Parenting Support from Family and Friends Scale). Results related to the relationship suggested that the larger difference between the groups referred to the behavior s category of helper, with higher occurrence in the Group 1 than the Group 2. This result was supported for the interview s report. Scales results indicated significant statistically difference between the groups only for the Parenting Support from Family and Friends Scale, with higher level of this support for Group 1. Thus, it is possible to suggest that because families from Group 1 have lower levels of support from families and friends than Group 2 (measured with the Parenting Support from Family and Friends Scale), there is a greater help required from the disabled member, which can be compensated by the brother or sister. Young siblings with typical development performed the helper s role in greater level than adults siblings do it. This research draws attention to futures investigations with larger numbers of participants, and to investigations of the relation between sibling s relationship and gender, and the severity of the disabled sibling. Key-Words: Siblings relationships; Mental Disability; Social Support; Observation.

The increasing rate of aggressiveness in childhood and adolescence has mobilized investments and research in search for a solution to this concern of the society at present. The related literature appoints parental educative practices as factors that contribute towards the risk and concealment of disorders of children s behavior. The parent training programs have shown themselves as a successful alternative in the treatment of behavior disorders in childhood. The purpose of this study was to adapt a parent training program with focus on Social Educative Skills of parents and evaluate its effects on the behavior of the children. The program was structured in nine weekly group sessions, lasting 90 minutes, held in a municipal school of Belo Horizonte, Brazil. Eight mother/child dyads have participated in the program and the infants mean age was 9.38 years (sd = 2.87), where 75% of which were male. The mothers behavior was randomly evaluated prior to and after the training process by using the Social Skills Inventory and video tapes, and the children s behavior was evaluated by using the Home Situations Questionnaire and the Disruptive Behavior Inventory. The data were analyzed as to statistical and clinical significance. The results suggest that there was a reduction in the frequency and seriousness of behavior problems in most children. Application of the Parent Training Program in a larger scale shall allow validating it for treatment of children s behavior problems in similar communities.

The present master s degree dissertation is structured around the following question: What do the works presented on ANPEd and ENDIPE say about the process of professional learning of teaching taken place in the beginning of the career? To answer it, a time cut-out equivalent to a decade of research (1995-2004) was performed, that is, a search on the annals of the last ten ANPEd Annual Meetings and the last five ENDIPEs was conducted, looking for the works that presented as main discussion focus the beginner teacher and its professional learning process, regardless of teaching level. The framework on which the research is based privileges three categories: the teacher formation models, advocating for the model of the teacher as an intellectual critic, that is, a teacher that recognizes the controversial nature of education, not conceiving it as a mere reproducer of the dominant ideology, but also as propelling spring of the social transformation; the characteristics of the beginning of teaching, such as, the feeling of reality shock, marked by the feelings of survival and discovery and the teaching knowing, which comes from various sources and is built, not only during the initial period, but throughout the whole career. Analyzing the results presented by the selected studies, it was possible to verify that: a) the prevailing teacher formation model is the practical epistemology, especially the one that understands the teacher as a practical reflexive professional; b) the characteristics of the beginning of teaching, pointed by literature, are confirmed, especially regarding the feeling of reality shock; c) the teaching knowing is plural, composite and heterogeneous, resulting from several sources (family, previous schooling, initial formation, experience). The data analysis allows pointing out also, as more emphasized aspects in the analyzed works: the professional socialization, the teaching knowing and the feelings of survival and discovery that strongly mark this career beginning, among others. Less emphasized aspects include: the relations between initial formation and professional insertion moment and the learning ways developed by the beginner teacher. Finally, silenced aspects include, among others: the continuous formation and professional development politics, diversity/difference questions, cultural plurality and multiculturalism, pedagogical practice analysis of the teachers of young and adults and the existing relation between the beginner teacher and its professional acting model. The model of the teacher as an intellectual critic, advocated by this work, was also absent from the discussions about the teacher in the beginning of career.

The present work aimed to study the morphology, taxonomy and bionomy of Ablabesmya Johannsen, 1905 (Diptera, Chironomidae, Tanypodinae) species of the State of São Paulo. This genus of world distribution prise 69 species, of which ten are registered in the Neotropical region, however none specifically mentioned for Brazil. The analyzed material derives from three lotic systems (streams and rivers) and seven lentic systems (reservoirs and lakes), which are located in three cities of the State of São Paulo (São Carlos, Luís Antônio and Brotas). The sampling followed the conventional methods of benthonic studies. The larvae were kept alive in the laboratory to obtain the associations between larva, pupa and adult. The identification of the species was based on the original descriptions. The results allowed the identification of eight species, seven of wich are new species and the second record of Ablabesmyia metica Roback (1983) for the Neotropical region and the first one to Brazil, describes the immature stages, unknown before. The new species are described with the respective diagnoses. The ecologic information on the genus are discussed and perspectives for the future studies are mencioned.

The importance of supply management for the automotive assemblers is justified by the contribution to the success of their business strategies, since more efficient supply operations would guarantee the profitability of these companies. Such operations are based in the supply of parts and components with the wanted quality, in the requested amount, in the stipulated period and at competitive costs. This work intended to study the way as two assemblers of Brazilian automotive industry are managing their respective supply bases, identifying the peculiar characteristics of supply management strategies and the way as these companies coordinate the relationships with their suppliers and influence the actions taken by them. For this, firstly a bibliographical research was accomplished to base the elaboration of a theoretical reference to developing a knowledge both of the theme and of the studied industry, besides establishing a conceptual structure used in the field research, which was composed by exploratory and qualitative case studies, accomplished in each analyzed company. After the description of the individual case studies, the obtained results were crossed and compared in order to identify similarities and differences among the companies. It was verified that the eastern assembler studied is more involved with the supply management activities in comparison with the western assembler, consolidated in Brazilian automobile industry. This perception results of its largest influence and participation about the operations of its suppliers, direct or indirect, by assuming the control of acquisition activities in the supply chain and to worry with their profitability. The western assembler, however, just maintain a larger involvement with its direct suppliers, besides not developing politics able to guarantee their operational profitability.

On this thesis some aspects of relaxation processes and decoherence processes using deformed algebras of the harmonic oscillator, particularly the generalized deformed algebra (GDA algebra) and Kerr algebra were studied.Two situations were considered for this study: a) The system of interest is described as a non-linear harmonic oscillator interacting with a dissipative environment (thermal reservoir), b) the system of interest ( non deformed harmonic oscillator) interacts with a thermal reservoir described by a group of nonlinear quantum harmonic oscillators. An interesting result was found for the two situations , where we notice that the master equation and the expressions found, show the strong dependence of the nonlinearity introduced by the deformed algebra. On case (b) the obtained equations have a form identical to the nondeformed equations, but show new nonlinear coeﬃcients not obtained in the reading.The influence of the reservoirs nonlinearity is noticed in the coeﬃcients found. The phenomenon of decoherence, considered the thermal nonlinear reservoir and the compressed air reservoir that were studied. The master equation that rules the dynamics of the system and an estimated a time of decoherence were obtained , along with important results. It was observed that when there is an increase on the deformed parameter there is also an increase on the decoherence time, showing the nonlinearity contained in the reservoir acts in a significant way over the time of decoherence of the system.

In this work we present the methodology of capture-recapture, under the classic and bayesian approach, to estimate the number of errors of software through inspection by distinct reviewers. We present the general statistical model considering independence among errors and among reviewers and consider the particular cases of equally detectable errors (homogeneous) and reviewers not equally e¢ cient (heterogeneous) and of errors not equally detectable (heterogeneous) and equally e¢ cient reviewers (homogeneous). After that, under the assumption of independence and heterogeneity among errors and independence and homogeneity among reviwers, we supposed that the heterogeneity of the errors was expressed by a classification of these in easy and di¢ cult of detecting, admitting known the probabilities of detection of an easy error and of a di¢ cult error. Finally, under the hypothesis of independence and homogeneity among errors, we presented a new model considering heterogeneity and dependence among reviewers. Besides, we presented examples with simulate and real data.

The reservoirs are artificial ecosystems constructed by the man and attend to the multiple uses. The reservoir provokes alterations in the aquatic ecosystem, causing modifications in the chemical and physical composition of the sediment and of the water and consequently in the circulation and the organization of the biological communities. The purpose of this study was to characterize the taxonomic composition and the benthic community density in 3 reservoirs of the Middle Tietê River (Barra Bonita, Bariri and Ibitinga), to analyze the physical and chemical characteristics of the water and of the sediment and to verify the possible relation of these with the structure of the benthic community, considering the populations of the native species and the invading species Melanoides tuberculata and Corbicula fluminea. The samplings were carried out in two climatic periods, the rainy season (November 2002) and the dry season (August 2003), showing three portions in each reservoir (upper, middle and lower) and following a sweeping with 6 sampling points in each transect. In each point, the samples of sediment were collected in duplicate with one drag of the type van Veen. Based on the limnological data the reservoirs of Barra Bonita and Bariri were classified as whereas Ibitinga Reservoir was characterized as mesotrophic for the periods evaluated. In November 2002, 21, 29 and 25 taxa of macroinvertebrates were registered in Barra Bonita, Bariri and Ibitinga reservoirs, respectively, while in August 2003, there were 23, 31 and 27 taxa, respectively, in each reservoir. A greater similarity between the benthic macroinvertebrates was found for the associations sampled in both periods in the same reservoir than between the different reservoirs, evidencing that each environment have a particular composition of taxa, although some taxa are common among them. The invading species M. tuberculata e C. fluminea were current in all the reservoirs, in both periods of sampling, except in the Barra Bonita reservoir. The generalized occupation of M. tuberculata and the high densities of this specie in the studied reservoirs reveal the high invading potential of same and the probable competition with the native species.

Considering that many researches show the importance of social skills not only for personal well-being but for a good professional performance as well, this research having as axis the theoretical-practical camp of Social Skill Training compares two samples of workers: (a) the ones with physical disability and (b) the ones without physical disability. The objectives in this study are: (1) to identify and compare the profile of workers with physical disability and workers without physical disability; (2) to classify and compare positive and negative aspects provided by the job; (3) to identify and compare the important social skills for the workplace; (4) to identify the importance of social skills in the workplace for the bosses; (5) to analyze and compare the social skills of workers with physical disability and workers without physical disability. Twenty-seven workers with physical disability (TDF), twenty-seven workers without physical disability (TND) and nine bosses (GS) participated in this study. The research has been done at five companies located in the inland of the state of São Paulo. The tools used were: Criterion Brazil, Interview, Checklist of Social Skills in Work and Inventory of Social Skills. The social-economic, social-demographic and Checklist results were analyzed according to the mean and standard deviation; the answers of the interview have been analyzed according to the category and frequency; in the Inventory of Social Skills the scores and the frequency have been considered. Finally, in the comparative analysis what was considered were the tendency (p<0,1) and significance (p<0,05), using Student t-Test (SPSS) and Chi-square test. As to the aspects provided by the job, TND presented more frequency of negative aspects than TDF. The analysis of the content has shown classes of positive aspects (Citizenship; Combination of Interest; Finances; Personal Appreciation; Professional Appreciation; Social Relations) and classes of negative aspects (Difficulty in Interpersonal Relations; Mechanical Work; Physical and Emotional Stress; Professional Worthless; Shift Work). In general, the results have shown that TDF and TND related a good repertoire of social skills and pointed out, together with GS, social skills in the workplace as very important. The comparative analysis has shown significant differences between TDF and TND. However, one concludes that the phenomena of physical disability must not constrain the body limit, because the social development of these people seems to suffer influence from both the context and the social relations as well as the social development of people without physical disability.

This research aimed at analyzing the computer’s indirect usage in the Chemistry teaching-learning process in high school. For such a purpose, two short pedagogical films (SPF), which contained images captured by digital camera and images produced by graphic design, were produced; it was studied as well the transmission of the audio that was added to the films during the edition’s period, such as narration, for instance. The usage of the films occurred through a mini course given to two different groups of students. There were two teams in the first group; the duration of this mini course was of a week, totalizing twenty hours. The second group was divided into three teams according to the students’ degree of scholarship in high school; it took three weeks, with four hours and a half of mini course to each team. It was also adopted a sequence of research during the application of these films: (1) the usage of an initial questionnaire about the topic to be studied, i.e.: the material physical properties; the chemical relationships; and the chemical equilibrium; (2) the introduction of the contents through a practical class with materials and experiences directly related to the topic; (3) the usage of the first film; (4) the formal presentation of the contents; (5) the usage of the second film; (6) and the application of a final questionnaire. It was possible to observe the assimilation of the showed contents by some of the students when both questionnaires were compared. The first group of students who took part of the mini course classes had better results of learning. The second team did not have so satisfactory results as the first one, perhaps because the time of the application period was not enough. At last, it was pointed out an optimized sequence to the production of SPF, close to those of this research
