Hemoglobin structural and functional aspects, as well as the presence of intraerythrocitic organic phosphates of 167 individuals of 10 species of bats, belonging to Phyllostomidae (Artibeus planirostris, Phyllostomus discolor, Artibeus lituratus, Carollia perspicillata, Desmodus rotundus, Glossophaga soricina), and Molossidae family (Molossus ater, Molossus molossus, Nyctinomops laticaudatus e Eumops perotis) were studied. These individuals were collected in different areas of São Paulo State. Hemoglobin of these individuals were submitted to starch gel electrophoresis and showed all the same pattern: one slow major, migrating close to A2 human hemoglobin and one minor fast component, migrating close to human hemoglobin A. No intra and inter specific variation were detected. Variations on functional properties in blood were detected. Most of the species (7) presented normal Bohr effect, while C. perspicillata, D. rotundus e M. molossus null Bohr effect. Artibeus planirostris presented reverse Bohr effect. All the hemoglobin samples showed normal Bohr effect in the stripped form as well as in the presence of 2,3-biphospho glicerate and inositol hexaphosphate. The addition of this organic phosphate has altered both Bohr effect and P50 values. The oxygen affinities were high in all hemoglobins. In vivo, the oxygen affinity of bat hemoglobins is lower due to modulator effect,probably ,3.biphospho glicerate. In the erythrocytes of all individuals studied 2,3-biphospho glycerate were found in varying concentrations and a little higher than most of Mammals. No inositol polyphosphates were found in any sample tested.

An important characteristic of the capitalist industrial production is related to the exploration of the scale economies in a widespread way by firms with the purpose of enjoying better economical results. This was the case of the steel industry, which, in order to meet the increasing needs of operational efficiency started to adopt larger and larger equipment and facilities in their industrial plants. This path was more intense in the integrated plants, which present larger size than the mini-mills . This work investigates the role of the scale economies in the metallurgical processing, through extensive bibliographical research in specialized literature and visits to different companies. Besides, numerous interviews with metallurgists from several areas of these industries have been done. The results indicated, among other things, that most of the semi-integrated plants now in operation do not fully explore the potential of scale economies associated to the process, for having been constructed in sub-optimal scale. In a more dynamic demand scenery, a better exploration of this economy is expected, where it would prevail the path of increasing scales for both technological routes, the integrated and the semi-integrated plants.

During the 90s, Brazilian market open to imported goods sets the beginning of food industry transformation in Brazil. Other factors led to competitiveness growth among food companies, such as: the development of new technology, and consumers knowledge and expectation level increase. Therefore, food companies were forced to seek for competitive advantage which allowed the differentiation of their products in the market. In this context, product development process (PDP) gains fundamental importance. Due to the importance of PDP in the food industry, this work seeks characterize the food product development process management. Besides, this work aims to characterize the capability to PDP. In order to reach these purposes, eight food companies and three organizations (ITAL, SENAI, and a consultant company) that backup food industry were studied. Three food companies were chosen out of the eight which were studied and were presented in this work. The chosen companies have a more structured PDP, which allows a discussion on capability building process. The findings showed that food companies follow a sequence of phases and activities during PDP. This sequence is very similar when food companies are compared with each other and with the theoretical background. Concerning capability, food companies see capability building restrict to courses, and to market fairs visiting. The organizations that backup food industry serve mainly small companies, which do not have either enough technical or managerial knowledge in order to develop a product. Therefore, we consider that food product development process management is based on technical aspects. However, a minimal of managerial structure has been started by the companies. Besides, the need to develop new products tends to make food companies put in resources to build capability.

This assignment has as aim to analyze the impact of forest certification about the work conditions of forest workers. It s believed that, although the origin of forest certification had been conditioned by market factors, its social worries are producing effect at companies that adopted it. In this assignment will be described the formation of forest complex, reminding the fundamental policies for the consolidation of the current Brazilian complex. It ll also be done a short discussion of the two forest certification systems used in our country: FSC (Forest Stewardship Council) and CERFLOR (The Brazilian Forest Certification System). The assignment advances at the discussion of the forest production process and the organization of work at forest production. In this sense, the contribution of this assignment is to identify the changes at the work organization, occurred after the certification and if improvements at work conditions of forest workers had happened.

Proteins from the inner core of HIV-1 are involved in crucial processes during the virus life cycle. p24 is the major capsid protein of HIV and is initially expressed as part of the gag polyprotein. The association of gag proteins to the cell inner-membrane surface initiates virus assembly and induces budding from the host cell membrane. Thus, p24 plays an active structural role both as part of the Gag protein and in its mature form. In this sense, we have chosen a region from C-terminal of p24, TLRAEQASQEVKNWMTETLLVQNA, (p24-3) which is part of the major region responsible for protein dimerization. The linear peptide, rp24-3, and its cyclic variant, rp24-3m, were produced by recombinant strategy in Escherichia coli. The gene fragments were obtained by the synthetic gene approach and inserted into pET 32a to produce fusion proteins in the soluble form. The expression products were purified by Ni-affinity chromatography followed by an enzymatic cleavage. The peptides where purified by reverse phase chromatography and their primary sequence and molecular masses where inferred by amino acid sequence analysis and mass spectrometry, respectively. The rp24-3 secondary structure was investigated by circular dichroism and steady state fluorescence, been structured differently in water and in buffer. Besides, its tryptophan is in a partially buried environment and the addition of methanol above 70% caused a highly increase in helical content. In conclusion, this work shows a suitable system for rp24-3 production, providing satisfactory amount for structural studies.

In the present study we determined the location and orientation of the CO2 and/or pH chemoreceptors and analyzed the cardio-respiratory responses and the aerial respiration in jeju (Hoplerythrinus unitaeniatus) during graded hypercarbia (1, 2.5, 5, 10 e 20% de CO2) and acid medium (pH ~ 7, 6.0, 5.8, 5.6, 5.3 e 4.7) (1, 2, 3, 4 e 5 mM de HCl). The chemoreceptors orientation was determined by means of a series of injections of different hypercarbic solutions (5, 10 e 20% de CO2) in the caudal vein (internal) and buccal cavity (external). To distinguish the orientation of the CO2 and H+ chemoreceptors, acid solutions (HCl) at same pH of the internal (pH 5.1, 4.9, and 3.7) and external (pH 5.6, 5.3, and 4.7) solutions were applied, and significant responses in relation to the control values were not recorded. In another group of fish previously tested acid solutions (30, 40, and 50 mM HCl) were injected. This injections caused a decrease in the extra-cellular blood pH to levels similar to those found during the injections of internal and external hypercarbic solutions. The location of the chemoreceptors was determined by bilateral denervation of branches of the cranial nerves IX (glossopharyngeal) and X (vagus) to the gills. The heart rate, arterial blood pressure, respiratory frequency and ventilation amplitude were recorded for intact and denervated fish. The data indicated that the CO2/pH chemoreceptors eliciting the cardio-respiratory responses to hypercarbia are exclusively branchial and are externally oriented. Jeju respond to hypercarbia of 5% CO2 with bradycardia, hypertension and increases in the ventilatory frequency and ventilation amplitude. Concentrations higher than 5% caused anesthetic effect. The cardiac responses are mediated by CO2/pH chemoreceptors distributed in all gill arches, while the respiratory responses are mediated by chemoreceptors located in the 1st gill arch. Furthermore, hypercarbia also induced aerial respiration in intact fish and in those with the 1st gill arch denervated. The denervation of the four gill arches did not abolish completely the aerial respiration, suggesting that chemoreceptors involved in this response are located in extra-branchial sites. The changes in the internal and external H+ concentrations or in the water did not affect the cardiorespiratory responses and aerial respiration frequency, unless if accompanied by hypercarbia.

A deaf child's birth brings the family into a new reality. Such reality might unchain anxiety states or not, depending on the conception the family has on deafness and deaf people as well as on interaction quality and established communication level. Facing that problem, this study aimed at getting to know the anxiety level of parents that attend orality services searching for oral interaction with their deaf children, and the anxiety level of those that attend bilingual services looking for interaction with their deaf children through the Brazilian Language of Signs (LIBRAS), homelike signs, speaking, and writing. In addition, this study has obtained and analyzed physiologic and behavioral measures of those parents that could be related to anxiety or not. For this, subjects took part in experiment sessions, where physiologic and behavioral reactions to stimuli were recorded and IDATE (Trace-Status Anxiety Inventory) was applied. The results of this study present difference among listener groups, orality and bilinguism as to the anxiety scale, with higher anxiety level among orality parents, while bilingual parents presented a higher anxiety than listener parents; however, this difference was not verified in physiologic measures, during the stimuli presentation. However, difference in those measures during experiment was found. On the other hand, behavioral categories indicated difference among groups. Having such results in mind, it would be interesting to confirm data from the anxiety scale with other scales, for instance, through application of Marilda Lipp s Stress test, the Analogical Scale of Humor, and Hamilton s scale for Anxiety.

The present study was an evaluation of the Bubble Concept a environmental criterium of compensation used by the United States Environmental Protection Agency and by the Environmental Agency of the CETESB in Cubatão, to regulate the implantation of new industrial enterprises and its amplifications. Studies ware done refering to the environmental licensing of the following industrial enterprise in the São Paulo State: Central of Energy Generatin of Santos lowland with the proposal of implantation in the area of the President Bernard s refinery in the Cubatão; Central of Energy Generation Carioba II, with the proposal of the implantation in the Americana town and a factory of Carbon Black, implanted in Paulínia. A bibliographic survey that included the scientific literature, that included national and international entities of research, Environmental Law of São Paulo State and Federal Environmental Law. In the stage of the interview technicians of the industries technicians of the Company of the Technology of Environmental Sanitation of São Paulo State were listened. Environmental Consultants, students of Pos-Graduation and Environmental Management of Santa Cecilia University, Justice Prosecutors and people of no governmental Organizations. It was concluded that the absence of criterium or even the use of criterium of environmental compensation with basis in the Bubble Concept founded in the exchange of pollutants in the proportion of 1:1 does not promote the improvement and the recovery of the quality of the air of the Regions and Sub-Regions saturated of atmospheric pollutants or in ways of saturation, contraposing itself to the Federal Law n. 6938. As an alternative to make the implantation of the new industrial enterprises or enlargements possible, with the improvement and recuperation of the air quality in Regions and Sub-Regions saturated of atmospheric pollutants this paper suggests several alterations in the Bubble Concept .

The deregulation and trade liberalization in the begin of the 1990 s created the need of competitive strategies in the domestic dairy industry, notably in Mercosul. The new environment imposed a number of changes in this sector, as far as producers and industries are concerned. This dissertation aims to evaluate the result of one of these changes that were implemented in order to gain competitive advantage, by way of quality differentiation or cost savings in logistics. It is a case study about the bulk collection of refrigerated milk at Nestlé Brasil Ltda, which is a very representative firm of the dairy industry and where, until 1995, milk was collected in gallons. This process could be implemented with the introduction of cooling equipments in farms, in a partnership between the industry and producers, and also by the improvement of the industry vehicles used for milk transportation. These investments have produced a number of logistic changes that had a huge impact in the group of suppliers and the whole process of milk purchasing and collection. In this context, this dissertation offers an analysis, from the point of view of supply chain management, focusing on the chain efficiency, and of the New Institutional Economics, focusing on transaction costs.

Down syndrome is the most frequent cause of mental retardation affecting millions of people worldwide and results from full or partial trisomy of chromosome 21 (HC21). Rare cases of partial trisomy allowed the identification of a small region in HC21 common to all carriers called Down Syndrome Critical Region. The genes DCRA and DSCR8, mapped to this region, encode two proteins of unknown function. With the aim of contributing to a better characterization of these proteins, DSCR8 was subcloned and expressed in fusion with thiorredoxin in Escherichia coli Rosetta (DE3). Recombinant Trx-DSCR8, observed in the soluble fraction, was subjected to the initial purification assays by affinity chromatography in a Ni-NTA column. The gene DCRA was cloned and expressed in fusion with the proteins thiorredoxin and GFP allowing the partial purification of the protein and the achievement of crystallization and immunological assays. The amino acid sequence of DCRA showed 57% and 49% of identity to a protein of unknown function from Anopheles gambiae and Drosophila melanogaster respectively. Also, in silico analyses revealed that DCRA contains a putative Vps26 domain. Subcellular localization of DCRA in fusion with GFP was observed preferentially in the cytoplasm of the cell lines tested. These results contribute to a better characterization of DCRA and DSCR8 and open up possibilities towards the understanding of the cellular role of these proteins and their relationship with the Down syndrome.

The synthesis of coordination compounds containing bipyridine derivative ligands and the influence of the substituent groups on the physical and chemical properties were studied in this work. Mixed compounds of the type [RuCl2(P P)(X bipy)] were synthesized, where X - bipy represents the bipyridine derivatives and P - P = triphenylphosphine (PPh3)2, 1,4-bis(diphenilphosphino)butane (dppb). The characterization of the compounds showed that the isomer formed in solution is dependent on the phosphine used. The isomer of the compounds containing the triphenylphosphine exhibited a structure where the phosphine groups are mutually in trans position. For the biphosphine compounds, dppb is trans to N-heterocyclic ligand. The spectroscopic and electrochemical properties of the compounds showed dependence with substituent group of the bipyridine. It was observed a linear correlation of the pKa values of the X-bipy ligands with the redox potential of the complexes. The decrease of the pKa value with the increase in the electronwithdrawing ability of the X groups makes the ligand less basic. This effect enhances the π-backbonding interactions, which implies in the energy decrease of the MLCT transitions and in the redox potential increase of the metal center. For the [RuCl2(dppb)(X-bipy)] complexes, the isomerization reactions under light incidence were monitored by electronic spectroscopy or differential pulse voltammetry. The photolysis study of the compound with the 2,2'-bipyridine ligand allowed the assignment of the field ligand state for its photochemical activity. The kinetic data supplied the assignment of a twist mechanism for the isomerization process. It was observed an increase in the rate constant value for this process with the increase pka values of the ligand. The reactivity of the compound [RuCl2(COD)]n, COD is 1,5- cyclooctadiene ligand, with the substituted bipyridine was studied in order to obtain compounds containing different compositions with changes in reaction conditions. Compounds of the type [RuCl2(COD)(X-bipy)], for X = H and Me, were obtained and characterized by microanalysis, hydrogen nuclear magnetic resonance (RMN) and electrochemical techniques. The reactions with other bipyiridines resulted in mixtures of compounds of hard purification, needing a more systematic studies for the correct attribution of their composition and structures. Tris(diimine)ruthenium complexes, [Ru(X-bipy)3](PF6)2 with X = H, Me, MeO, MeS, were obtained and characterized by microanalysis, hydrogen nuclear magnetic resonance and electrochemical techniques. With substituent groups containing sulfur atom, MeS and MeSO, polinuclear complexes were obtained. The [RuCl2(P-P)(MeS-bipy)][(µ)-RuCl2(P-P)], [RuCl2(CO)(PPh3)2]2[(µ) RuCl2(dppb)(MeS-bipy)] and {[RuCl2(dppb)]3[(µ)-Ru(MeSObipy) 3]}(PF6)2 compounds were synthesized and characterized by spectroscopic and electrochemical techniques. An interesting electronic conducting mechanism was observed. The sulfur atom is believed to withdraw electron density of the metallic center by backdonation interaction transferring to the pyridine ring which, by being more basic, transfer part of this density to the second metallic center.

In a highly competitive market as the actual one, the production management must ensure that goods and services are supplied to the customers in right time, so they can offer a competitive advantage or, at least, can be sold by a price that surpasses the production costs. It can be affirmed that one of the variables which determines the service level, to the customer, is the product availability, such in rapidity terms, as the amount of the available product. A determinant function for the availability of a product or service is the forecasting, it analyses the records about the past sales and it infer the possible behavior of the consumers for the following periods. The demand is influenced by qualitative and quantitative factors that are not considered simultaneously by the traditional forecasting methods. Thus, observing the trends in the use of expert systems and the importance of the demand forecast, this research aims to develop an expert system for demand forecast that combines qualitative and quantitative methods. To test and to analyze the performance of the systems a case study in an industry of soft drink had been carried through. This work considers an adaptation to the method of quantitative forecast adjustment with judgment to develop an expert system for demand forecast. The quantitative forecast is outcome by the combination of the forecasts generated for the most known methods. The results obtained in the tests carried through with data that had been collected during the study case confirm that the use of judgment as adjustment form of forecasting obtained by quantitative methods improve the quality of the forecast. Moreover, this work allowed proving that the knowledge of an expert who calculates the forecasting using his own judgment allows the construction of a Knowledge Base of an Expert System.

studies about muscle regeneration and injury used invasive methods in animals. Although the muscle regeneration process in many mammals is similar to the one found in humans, it is necessary to improve the application of non-invasive procedures used in the evaluation of the muscle regeneration and injury in humans. Non-invasive techniques such as surface electromyography, isokinetic dynamometry and nuclear magnetic resonance (NMR) for imaging have been used in studies in humans for the evaluation of the skeletal muscle. However, studies in which all these procedures are used together, allowing a more detailed evaluation of the muscle morphology and function, are rare.Thus, the aim of this study was to evaluate the behaviour of the medium maximal isometric torque, the electrical activity and the muscle pain before the injury, during the 7 days after the injury and also between the 21st and 30th days after the injury, when the muscle has already regenerated. For this, a injury was induced in the quadriceps femoris muscle through intense eccentric exercise. To confirm if the model utilized was effective to produce the muscle injury, the plasma activity of the creatine kinase (CK) was also evaluated and the NMR for imaging of the quadriceps femoris muscle was realized. Ten university student volunteers (21,9±1,5), sedentary and without musculoskeletal dysfunction in the lower right limb participated in this study. The extensor medium maximal isometric torque was evaluated through maximal isometric contraction with the knee joint at 90º of flexion, in the isokinetic dynamometer (Biodex Multi-joint System 2 da BIODEX MEDICAL SYSTEM Inc). The electrical activity (Root Mean Square-RMS and Median Frequency) of the vastus medialis oblique (VMO), vastus lateralis (VL) and rectus femoris (RF) muscles was analysed simultaneously to mensuration of the isometric torque, utilizing a Digital Analogue Conversor A/D (LYNX) and single differential active electrodes of surface (LYNX). The quantitative and qualitative analysis of the pain were realized by Visual Analogue Scale (VAS) and by Brazilian Version of Short-Form McGill Pain Questionnaire. The activity of CK was measured utilizing the Kit CK-NAC UV unitest (Wiener lab) and the NMR was realized in the ToRM 0.5 equipment. For the induction of quadriceps femoris muscle injury, the volunteers were submitted to 4 series of 15 maximal eccentric isokinetic contractions, at angle velocity 5º.s-1. The results of this study demonstrated that the medium maximal isometric torque reduced significantly until the 4th day after the eccentric exercise (immediately after and 1st - 4th days after, p<0.01; 4th day after, p<0.05). The RMS of the VMO, VL and RF muscles reduced significantly the 2nd day after (p<0.01, p<0.01 e p<0.05, respectively). However, the RMS of the VL and RF muscles between the 21st and 30th days was significantly greater than before the exercise (p<0.01). There wasn t alteration in the median frequency after tthe eccentric exercise (VMO, p= 0.90; VL, p= 0.55 e RF, p= 0.89). The intensity of pain was greater until the 3rd day, and the peak occurred in the 2nd day after (p<0.01). The McGill Pain Questionnaire demonstrated that the word heavy was the most used to describe the pain after the induced injury by eccentric exercise. The peak of activity of the CK occurred in the 2nd day after the eccentric exercise(p<0.05). The evaluation by NMR demonstrated that the greatest extension of injury occurred in the 2nd and 7th days after, and some voluteers still showed injury sign between the 21st and 30th days. In conclusion, the eccentric exercise reduced the medium maximal isometric torque, increased the activity of the CK, changed the RMS and resulted in pain, which were gradually recovered in one week, despite the presence of muscle injury.

This research has compared the coordination and relation structures in two truck manufactures in Brazilian automotive industry. The network analysis level has been consolidated as an adequate approach in order to understand the cooperation/competition binomial, which involves the markets and the relationship among economic actors. In the network analysis, it has been assumed that the environment in which the organizations work is structured by technological and productive vehicles, established between companies and institutions. Within the field of economic sociology and the organization theory there is an increasing concern in order to understand how a structural position and the type of relationship among the economic actors in a certain network have influenced the organization performance and its strategic behavior. Over the last decade, it has been observed a deep structural change within the Brazilian automotive section, with direct consequences in the suppliers network. The direct consequence of this change is the set of opportunities that truck manufactures and autopart suppliers can obtain from their relational and structural positions within the Brazilian automotive sector. The central issue of this work is related to how the different relational and structural positions of the autopart suppliers in the automobile network influence the diffusion levels of knowledge, the truck manufacture control over the suppliers and their relationship of power. The conclusions of this research have revealed that the cohesive and dense relationship has great possibilities to promote diffusion channels between truck manufacture and autoparts in order to generate distinctive and highly institutionalized control structures on the suppliers and, also to redistribute the power of decision to autopart suppliers.

The goal of this study was to analyze the factors which influence the process of accepting and coping with blindness for those who have lost their eyesight through accident or disease in adulthood. Twenty individuals (14 men and 6 women) between the ages of 24 to 64. Ordinary materials such as blank paper and pencil were used for recording scripted interviews and analysis of interview transcripts. The interviews were held in a room in the Rehabilitation Section at the Benjamin Constant Institute in Rio de Janeiro. A semistructured interview was utilized to collect data and allow the elaboration of themes and categories enabling the understanding of which factors influenced the process of accepting and coping with the loss of eyesight in adulthood. The quantitative analysis was done by recording the frequency of elements which the participants did or did not present within each category. The qualitative analysis considered the variations in participant responses within the respective categories. The results presented evidence that the factors which favor the acceptance of and abilities to cope with blindness acquired in adulthood were: the family, the impact of blindness on their lives, the moment of loss, social life, the activities which were interrupted by the loss, support, religion, the cause (whether accident or illness), feelings and their plans for the future. Analysis of the data indicated that the process of accepting and coping with the disability developed in a gradual manner and support, whether from family or professionals, contributed to the affected person's adjustment in society. For this reason, it was concluded that the acceptance and coping with blindness acquired in adulthood can not be described in a homogeneous form. Each individual presented their own characteristics which made them react differently to innumerous life situations.

This work presents and discusses results of the effects of doping on rare earth-doped nanosize SnO2, obtained using the polymeric precursor method and prepared at different annealing temperatures. Only the cassiterite phase was observed for the rare earth-doped SnO2. Structural and morphological studies in pure and rare earthdoped tin dioxide were performed in samples. The rare earth-doped SnO2 showed high stability against particle growth at temperatura below 1000 0C. A doped-rich surface layer was used to control the particle size and stabilize SnO2 against particle growth. It showed that the modification of the nanosized structure and the composition of particles lead to interesting selectivity changes for the methanol decomposition and was reported the catalytic performance of earth-doped materials on methyl-vinyl-ketone formation. NOx gas-sensing as well as electrical properties have been investigated.
