This work presents a proposal of implementing an Ordering System based on the Bata Manufacturing Strategy (BMS). The aim is to verify the interference and effectiveness of this system on the activities of the Production Planning and Control of a thermoplastics process factory. Its theory s reference comes from the Bata Manufacturing Strategy (BMS), the Ordering Systems (OS) and the Performance Measurement Systems (PMS). The Action- Research method was used to verify the relation between the ideal model and the one obtained when put on a practical experience. Firstly, a model system is proposed on what this work was developed, its main features and details that connect the BSM, the OS and the PMS. Then, an application example of the system in a thermoplastics process factory is showed using the blow molding process of High Density Polyethylene and Polyvinyl Chloride bottles for cosmetics industries and drugstores. Furthermore, the main results obtained when implementing this system are also presented as well as an evaluation of the procedures created to control the material and human resources and how these controls influence the Production Planning and Control activities of this factory. Another important point of this work is also to present a new approach on how to implement the Bata Manufacturing Strategy

The aim of this study was to understand the technique construction role as well as the knowledge in consolidation of the aeronautics design and upbringing productive competence. In this way, it identified the representations from different actors over the constraints that acted in the start of the aeronautics production, and turned evident in the strategies adopted by assemblers, and managers facing the constraints. It was done an ergonomic analysis of this work, based on observations, interviews, surveys and confrontation group. The riveter assembler, while realize his work activity provoke a sense motor action and promotes a confrontation of intentions, gesture and results producing news ways of know-how . The new know-how , therefore, seem to comply an absortion cycle by the productive organization which is shaped by the product maturity process. The viability of manufacturability makes itself up to the subject ability to incorporate adjustments or indicates changes. The system stability and aircraft own homologation derives from the technique formation, the meta-functional activity and the incorporation of the assemblers knowledge.

In the current competitive and dynamic environment, with constant changes concerning consumers' preferences, competitors' actions and also political and economical changes in different countries, marketing strategies are even more relevant as the market has reached a more significant role in the definition of the tendencies and the success or failure of companies. Among the marketing strategies, in this paper, branding strategies deserve more attention as they are also responsible to assure the company sustainable competitive advantage. Considering the retail sector, the brand is also one of the most important concepts in the marketing strategy, mainly because consumers usually make different analysis about the products from their brands, especially about image perception, price, value and quality. The identity of the brand's owner has a significant impact over the impressions consumers may have about this brand. Therefore, the decision about brands patronage is very important for retailers including the choice between offering national brands (that belong to manufacturers) and/or private labels (that belong to the retailers). The focus on this thesis concerns the study of private labels strategy in food retailers in England and in Brazil. In order to achieve the objectives of this study, a qualitative approach and the case study procedure have been used. As the empirical research was developed with different retailers and suppliers in England and in Brazil, the research strategy used was multiple cases study, as multiple experiments (with replication logic). For the interviews, semi-structured scripts were used. The results from the empirical research were presented individually by company and then by country. The results from both countries were analysed in a comparative way. From the comparative analysis, it was possible to identify the distinct characteristics of each country, as well as the factors responsible for the differences in retail and private labels. After the comparative analysis, it was possible to elaborate recommendations to help and guide retailers that are analysing the possibility to adopt private label strategies. A model was developed to summarize the main elements to be considered by food retailers during the decision of adopting private labels. Finally, limitations of the research and suggestions for further researches were presented.

Young offenders deficits in problem solving skills are described as one of the characteristics of this population. However, there is no data in the Brazilian literature measuring this variable. This study had two aims. Firstly, a group intervention with young offenders was conducted with the aims of promoting the discrimination and emission of competent social responses associated with their psychosocial well-being (Study 1). Six male young offenders took part of the intervention program. The study was conducted in a young offenders Detention Center in the interior of São Paulo State, Brazil. Instruments used to assess the intervention were: Guided Interview, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Beck Hopelessness Scale (BHS), Social Problem-Solving Inventory-Revised (SPSI-R) and, School Performance Test. The intervention program consisted of three pre-intervention sessions to gather data, and ten intervention sessions in problem-solving skills training, followed by a three month post-intervention follow-up. Results indicated a history of school failure and violence victimization, as well as the use of alcohol and drugs, and involvement in aggressive episodes. High level drop-out rates was observed in this study: only two participants were present in all phases of the intervention. In the pre-test, five participants indicated anxiety and depression, and four participants indicated hopelessness. In the post-test, one participant indicated a decrease of depression, anxiety and hopelessness; the other participant maintained of depression levels (in the low range), anxiety (low) and hopelessness (low). Five participants took part of the Follow- Up. All participants indicated a decrease of depression in that phase. In terms of anxiety, in the participants who were present in all phases, one decreased his level (from severe to low), and the other presented the same performance (low). Other participants indicated: maintenance (low and moderate) or an increase (low to moderate). In terms of hopelessness, among the participants who were present in all phases, the same performance was maintained (absence). The others showed: maintenance (moderate/low) and a decrease (severe/moderate) of performance. The Social Problem- Solving Inventory-Revised data showed that four participants performance were in the average range of the normal group, and two had deficits in this area. In post-test, one participant increased his performance, and the other maintained it. In the Follow-Up, the performance varied from average to much above average. In spite of the study s methodological limitations, this is the first study in Brazil to investigate group social problem solving skills with young offenders in a Detention Center, and the first to utilize one specific instrument to analyze social problem repertory solving in this population. The second study adapted to Portuguese the Social Problem-Solving Inventory-Revised (SPSI-R), and investigated its evidence of criteria and content validity. Seventy six male adolescents took part of study, being 38 offenders and 38 no-offenders. The study was conducted in a Young Offenders Center, and at a public school in the city of São Carlos en São Paulo State. The instrument used to assess the study was the Social Problem- Solving Inventory-Revised (SPSI-R). The instrument was applied in group, and the time of application was approximately 30 minutes. In terms of content validity, the study showed a 95% agreement among assessors. In terms of criteria validity, the results showed that the instrument could discriminate offenders from the non-offender population. The development of intervention programs and instruments specific to this population is much needed, as the numbers of studies in this area is reduced in Brazil.

Important advances have been achieved in the granting of credit, however, the problem of identifying good customers for the granting of credit does not provide a definitive solution. Several techniques were presented and are being developed, each presents its characteristics, advantages and disadvantages as to their discrimination power, robustness, ease of implementation and possibility of interpretation. This work presents three techniques for the classification of defaults in models of Credit Score, Classical Logistic Regression, Bayesian Logistic Regression with no prior information and Artificial Neural Networks with a few different architectures. The main objective of the study is to compare the performance of these techniques in the identification of customers default. For this, four metrics were used for comparison of models: predictive capacity, ROC Curve, Statistics of Kolmogorov Smirnov and capacity of hit models. Two data bases were used, an artificial bank and a real bank. The database was constructed artificially based on an article by Breiman that generates the explanatory variables from a multivariate normal distribution and the actual database used is a problem with Credit Score of a financial institution that operates in the retail Brazilian market more than twenty years.

A multicommutation flow system for the spectrophotometric determination of hypochlorite in bleaching products using a cell with pathlength of 1 cm is proposed in this work. In this system, N,N-diethyl-p-phenylenediamine (DPD) reacts with hypochlorite and the product was monitored at 515 nm. The analytical curve for hypochlorite was linear in concentration range from 2.68x10-5 to 1.88x10-4 mol L-1 (2 to 14 mg L-1) with a detection limit of 6.84x10-6 mol L-1 (0.51 mg L-1). The sampling rate of 45 h-1 and a relative standard deviation of 1.4 % (n = 10), were obtained. The recovery of this analyte ranged from 97% to 102.5%. The results found for six bleaching products using the proposed multicommutated flow system agreed with those data obtained using a reference method (iodometric titration) at the 95 % confidence level. A multicommutation flow system for the spectrophotometric determination of chlorine in water samples using a cell with 100 cm of pathlength is also proposed in this work. In this system, dichloridrate orto-Tolidine (3,3-dimethyl bencidine) reacts with chlorine and the product was monitored at 438 nm. The analytical curve for hypochlorite was linear in the concentration range from 1.34x10-6 to 2.01x10-5 mol L-1 (0.1 to 1.5 mg L-1) with a detection limit of 9.4x10-8 mol L-1 (7.0x10-3 mg L-1). The sampling rate of 45 h-1 and a relative standard deviation of 1.0 % (n = 15), were obtained. The recovery of this analyte ranged from 96.8% to 104.6%. The results found for six water samples from São Carlos city using the proposed method agreed with those data obtained using the method used by CETESB (Kit DPD colorimetric) at the 95 % confidence level. The long pathlength optic system is composed by amorphous fluorpolymeric Teflon AF2400tube with a 100 cm of length and refraction index smaller than the water one that was used as wave guide, aiming to minimize radiation losses. Finally, flow system involving multicommutation was developed to increase analytical features, decrease the reagents consumption and residual production.

This research purpose is to verify the relation established between teacher valorization and educational quality in the FUNDEF creation bases and in the São Paulo state and municipal implantation, analyzing how this relationship reflects the teacher's valorization. This research is based on interviews and bibliographic, documented and speaking analysis, having Gramsci as main reference. In the Fernando Henrique Cardoso government the teacher was considered the major educational quality agent. However, this same government reduced the educational investments, according to the established goals to achieve the State Reform, impacting directly in the educational quality and teacher s valorization. In the São Paulo State, based on its ample Federal Government politic relationship, despite of its intense changes in the São Paulo pedagogic-organizational model, its initiative wasn t followed proportionally by the financials investments according to the expected, explaining the speech increasing performed between the teacher s valorization and educational quality. Related to the municipal research, this instance was limited to follow the Federal and the São Paulo State directions based on its inexperienced administrative skills in the educational area, reproducing insufficient teacher s valorization actions, under the idea to achieve local educational quality. Thus, in spite of the teacher to have your role officially outstanding in the period, less and less the educational resolution problems were approached in political-financial performance terms of the Union, of States and of the Municipal districts. This discussion was transposed strictly for a pedagogic and educational ambit, of the teacher's responsibility, and the teacher's valorization, linked to the meritocratic principles, becoming ideologically the bad or good educational quality reason, and not part of this process. Key-words: teacher valorization, educational quality, FUNDEF; educational politics; decade of 90

Nowadays, the flux method is one of the most widely used techniques promote growth of YBa2Cu3O7-ä single crystal superconductor. By using the material in a melted state, the reactions due to temperature are possible. To prepare single crystal superconductors of the family Y-Ba-Cu-O, a long period of time is necessary to melt the material in adequate conditions. In order to do this a satisfactory performance of the crucible is required; it must be resistant to any kind of chemical attack. In this work some materials used were investigated in crucibles. Platinum, gold (noble metals), oxides like Al2O3, ZrO2 showed problems when used in processing Y123 superconductors. To avoid this problem the zirconiaytria system is largely applied. Some authors have investigated the SnO2 crucible, but they found problems related to the densification of the SnO2. Recently, it was discovered that SnO2 can be densified without liquid phase, showing 99,7% of the theoretical density when sinterized up to 1300°C. Then, this condition was used to produce crucibles by slip casting to form the YBa2Cu3O7-ä single crystal superconductors without contamination. It was observed, in a first instance, that SnO2 crucibles are resistant to chemical attack of the flux that is rich in barium and copper. During the process it was observed an interface wall between the vial and the flux formed by BaSnO3. This protection is formed after heat treatment at 1025°C during 4, 17 and 24 hours. By increasing the treatment time (up to 24 hours), it was observed that the wall thickness increased too and it was possible stablish a relation between treatment time/thickness wall (that defines the resistance of chemical attack). This enabled the determination of the SnO2 crucible resistance to corrosion, under the flux condition. The second part of this work involved the Y123 single crystal growth. After produced, they were analysed by x-ray diffraction and SEM with microanalysis in cross sections of the crucibles to observe the BaSnO3 interface. It was observed that single crystals were not contaminated by tin, and they were analyzed through measuring magnetization vs. Temperature. The single crystal showed a critical temperature (Tc) around 90,5K with a transition width (Tc) around 19,5K before treatment with an oxygen flux at 450°C. After seven days of a second treatment under the same conditions, the Tc was increased to 92K with a decreasing to 4,5K in Tc. The results showed that SnO2 vials are resistant to BaO-CuO flux and appropriate to single crystal growth in YBa2Cu3O7-ä superconductors without external.

In the present work, analytical procedures were developed using the multicomutação concept and inhibition of the chemilumenescence for the pharmaceuticals determination, such as, captopril, dipirona and paracetamol. For the control of the analysis module and acquisitions of data a microcomputer was used Pentiun 233 MHz equipped with an electronic interface (PCL - 711S), through programs in language Lab - View 7.0. The detection module consists of a cell of flow of polyethylene (in spiral) of 100 cm, a silicon fotodiodo (OSD-50E) and an electronic device (I model FAC 500), for the conditioning and amplification of the signs chemiluminescents. The analytical procedure was used for captopril determination in pharmaceutical formulations, the system bases on the inhibition of the sign chemiluminescence, between the luminol and the hypochlorite of sodium, when inserting the drug in the system. The analytical curve obtained was linear from 7,5 x 10-6 to 1,0 x 10-4 mol L-1 and detection limit was 9,0 x 10-7 mol L-1 with an analytical frequency of 180 h-1. The same system was used for dipirona determination, that system bases on the oxidation of the dipirona for the hexacianoferrate (III) of potassium, that is the catalyst of the reaction among the luminol-H2O2 happening like this the decrease of the sign quimiluminescente. The analytical curve presented a lineal strip of 1,0 x 10-4 to 9,0 x 10-4 mol L-1 with limit of detection of 9,0 x 10-5 mol L-1 obtaining an analytical frequency of 215 h-1. The studied analytical procedure, for the paracetamol determination in pharmaceutical formulations bases on the consumption of the reagent in excess of hypochlorite of sodium for the drugs, happening from that way to the decrease of the magnitude of the analytical sign. After the optimization of the system it was obtained a lineal strip of answer of 5,0 x 10-6 to 9,0 x 10 -5 mol L-1 with a limit of detection of 2,35 x 10-6 mol L-1 and a frequency of sampling of 180 determinations per hour. In the procedures quimiluminescentes involving multicommutation system stands out the bass consumption of reagents as well as a good analytical frequency.

The aim of the present study was to evaluate the effects of L-Histidine (a histaminergic precursor) on anxiety and memory retrieval in mice using the elevated plus maze (EPM). The test was performed on two consecutive days. On the first day (T1), the animals received an i.p injection of saline (SAL) or L-Histidine (LH), 40 minutes before the test at dose of 200mg/kg and 500mg/kg. The following experimental groups were formed: SALSAL (n=10-11); SAL-LH (n=10-10); LH-SAL (n=10-13) and LH-LH ( n=10-15). Testing begun by placing the subjects on the central platform of the maze facing an open arm and test sessions were 5 min in duration. A similar procedure was carried out for animals in the retest condition (T2) (i.e prior maze experience). During the test we analyzed behavioural parameters that comprised both conventional and ethological measures. All sessions were video-recorded by a camera positioned above and ~50 ° to the maze. Conventional measures were the frequencies of total, open (OAE) and closed arm entries, time spent in open (OAT) and closed (CAT) and central parts (CT) of the maze, and its respectively percentage %OAT, %CAT and %TC. Ethological measures comprised frequency scores for rearing; head-dipping (Dip) and stretched-attend postures (SAP). No significant differences were found, at the 200mg/kg dose, in open arm entries (Kruskall-Wallis; P= 0,1537) and open arm time (Kruskall-Wallis; P=0,824;), and at 500mg/kg dose no significant differences were observed in OAE and OAT [F(1,48)= 43,56; 13,01, p< 0,05, respectively) between the Sal-Sal and LH-LH groups in T1, indicating that L-histidine had no anxiolytic effect. At 200mg/kg dose a decreased of OA entries was observed for the SAL-SAL (Wilcoxon; P=0,017823), SAL-LH (Wilcoxon; P=0,00021) and LH-SAL (Wilcoxon; P=0,007) groups and in the OA time only for the SAL-SAL (Wilcoxon, P=0,0166) and SAL-LH (Wilcoxon; P=0,0284) groups. At the highest dose the LH-Sal group reduced open arm time and entries ([F(1,48)= 13.01 and 43.56; p<0.05) on the second trial, indicating that acquisition and storage was not affected by LH. Further, the LH-LH group did not reduce exploration time of the open arms during re-exposure, in both days indicanting an inability to evoke memory. No alteration in the locomotor activity represented by CAE was observed (p>0,05). Regarding a ethological behaviors, in both doses, the frequencies of Dipping was decreased (p<0,05) in the reexposure. In both treatment, the LH-LH group did not reduce the ratio of SAP during the retest, indicative of failure to evoke memory (p<0,05). Therefore, our results indicating that LH did not show anxiolitic effects but induces a state-dependent memory retrieval deficit in mice

The relation between learning disabilities and school subjects can be easily seen by lay people as well as by professionals and students in the area. Besides this relation, literature has shown that a child s family environment, mainly the parents, play an important role in either strengthening or weakening social skills and study habits. This research was aimed at testing the effects of a training program in educational social skills for parents on their children s school performance. The present study involved 15 parents whose children, 1st 8th graders from public and private schools, were denominated by their children as having scholl problems. Parents were divided randomly in an Experimental Group (N=8) and a nonequivalent Control Group (N=7). The training program in social skills for parents was structured in thirteen sessions which took place once a week, each lasting approximately 120 minutes, in a Psychology Clinic located in a town in the state of São Paulo. Instruments of direct and indirect verification were used to evaluate behavior: filming, Checklist for parents and Test of School Performance ( Teste de Desempenho Escolar , TDE-Stein, 1994). The study was divided into four stages: (a) initial evaluation; (b) intervention; (c) final evaluation; and (d) follow-up after six months. Descriptive statistics was used to present data and content analysis was used to interpret the results, especially with regards to its clinical relevance and social acceptance. Results suggest that there has been an increase in social skills reported by the parents and an improvement in their children s school performance after intervention. Parent s social skills seem to have contributed positively to the reduction of their children s school problems. Parents who are highly involved in their children s lives can behave in desirable manner with regards to helping in school chores, as well as serving as good models in social and academic situations, which in turn help improve children s social and academic skills. The training program in social skills for parents has proved to be an effective method to solve interaction problems, especially those related to the school problems complaints on the school performance and/or related to the social interactions in classroom. These results also demonstrate the importance of positive involvement from both parents on their children s social-emotional development and school performance and the necessity of training programs for parents.

The high deforestation rate of the tropical forests is considered a great challenge to the conservation programs. The reduction of the original size of the natural forest areas and the isolation caused by the fragmentation of these areas constitute great menaces to the biodiversity conservation. In doing so, the Atlantic Forest constitutes one of the more richest and threatened forests of the world with urgent need of conservation, management and recuperation. In this way, studies that they contemplate the analysis of the dynamics of landscapes constitute in fundamental activities for an integrated management of the natural resources at local and regional scale, providing subsidies for the strategic planning and for the environmental management of landscapes intensely fragmented. This work had as objective the identification and the analysis of remainders of natural and semi-natural vegetation with priority for the biodiversity conservation in Geographic Microregion of the Erechim (RS), submitted to the environmental dynamics of the loss processes, fragmentation and regeneration of habitats, as subsidy for the elaboration of conservation plans, as well as for the future amplification of the Reservation of the Biosphere of the Atlantic Forest. The methodological procedures were accomplished in SIGs IDRISI ANDES and MAPINFO PROFESSIONAL 8.0 and they involved: verification of the dynamics of the loss, fragmentation and regeneration of habitats, using images of the satellites LandSat (TM5 - 1984 and 1992) and LandSat 7 (ETM - 2002); analysis of the ecological integrity of the fragments by means of the Indicator of Ecological Integrity (IEI) with base in the referring information to the vegetation fragments, Probable Minimum Age (PMA) of the areas of the fragments and of a Edge-Core Gradient (ECG); evaluation of the susceptibility of the fragments to the environmental risks with the use of four factors (distance to the forest covering, distance to the hidrografic net, proximity to the urban centers and proximity to the roadways); culminating in the identification of areas with priority for the conservation by means of the correlation between the data of susceptibility to the environmental risks and ecological integrity of the fragments. Great losses didn't happen in the total area occupied by vegetation, which presented an amplification among the years of 1984 and 1992 (5,07%) and posterior reduction between 1992 and 2002 (5,36), staying in just 16% of the total area in 2002. More than 86% of the fragments possess inferior area to five hectares, representing 23% of the total area occupied by vegetation, and 102 fragments just possess superior area for 100 ha, corresponding 19% of the total area of vegetation. Areas that apparently didn't suffer surface alterations in the analyzed period, presenting PMA 20 years old, corresponded at 56,4% of the area of vegetation. In the analysis of ECG, it was verified that 26% of the area of the vegetation are located in the core (considered as distant area in more than 60 m starting from the edge with the not vegetated border) of the fragments, being more than 70% represented by edge area. IEI varied of zero for 95, and more than 96% of the fragments were classified between the classes of smaller integrity, representing 46% of the total area of vegetation and 1,3% of the fragments reveals areas with larger relevance for biodiversity conservation, with larger integrity of habitats. In the analysis of risks 37% of the fragments they are less subject to risks, and the areas with larger risks constitute 38% of the fragments, more than 26.000 ha of vegetation. In the analysis of areas with priority, they were identified 177 fragments with larger priority for conservation, comprehending 20.000 ha of vegetation approximately. The obtained data guide to the fragment-key identification with larger potential for the conservation of the regional biodiversity. In this context, the evaluation of the correlation between the ecological integrity and the environmental risks of the vegetation remainders, submitted to the loss processes, fragmentation and regeneration of habitats was effective in this identification, could be an alternative in short or medium period for the delimitation of areas with potential for conservation as subsidy for more specific studies, in level of populations and flora and fauna communities.

Background: aiming to implement software processes quality models for small companies, several projects were developed in collaboration with Universidade Federal de São Carlos and USP São Carlos research centers. In this context, it was identified the need of improving the process of project management. Aim: this work presents a strategy that facilitates the management of software projects adjusting the Use Case Points method so that it effectively reflects the development team characteristics and the system planning to be developed be close the reality. This adjust comes from the application of the PSP (Personal Software Process) process activities and from a constant evaluation of the activities in course, together the actualization and control of the elaborated project planning. Method: this strategy was extracted from the systematic application of both the PCU method and PSP process, in the small companies’ environment, so that the project progress can be always evaluated. On account of this, it was identified the necessity of adjust the Effort Level (NDE – in Portuguese) per Use Case Point as well as the environmental factors of the PCU method per developer. The monitoring of the project through the PCU method variables adjustment, based on the PSP activities, resulted in the definition of the PCU|PSP Strategy, proposed here. Results: the strategy is being actually applied in small software companies, as shown in the two case studies presented in this work. The obtained results indicate its contribution to the quality improvement of the management software projects, mainly in relation to the planning and control activities. Conclusion: based on the obtained results, the strategy has achieved the objective of facilitating the implementation of process quality models, like the MPS.BR, only in respect to project management. Besides, the strategy is perfectly adjusted to the Scrum agile method, making agile and controllable the project management, what is a positive point, mainly in the context of small companies.

The present work had for aim to survey of Pimplinae fauna in area of Atlantic forest at Campos do Jordão, SP, contributing to the taxonomic knowledge of the group as well to investigate the occurence of possible pattern of spatialdistribution of those insects, considering a altitudinal gradient (600- 2000m) and the seasonal influence that the study area is submitted. Using Malaise traps and "sweeping" the vegetation in 15 points in different altitudes were obtained 546 identified specimens distributed in 16 genera and 65 morphospecies. Schyzopyga Gravenhorst, 1829 was mentioned for the first time to Brazil. For the genera Hymenoepimecis Viereck, 1912 and Zaglyptus Foerster, 1869 three and two new species were described respectively. The species of Pimpla Fabricius, 1804 and Neotheronia Krieger, 1899 were the most frequent. It was not possible to observe a distribution pattern according to the gradient altitudinal for the community of Pimplinae. The results obtained in this study enlarge the knowledge regarding the distribution of Pimplinae in neotropical region, and contribute to studies about distribution of parasitoid insects along an altitudinal gradient

In this work Cobalt and Titanium doped Barium hexaferrites were synthesized by the ceramic method in order to study their use as electromagnetic absorbing materials in high frequencies. The dopants were used individually (Ti and Co) and with both simultaneously (CT). Ceramic characteristics and magnetic properties of calcined powders, as well as of their pellets sintered in electric and microwave furnaces were evaluated. For the high frequency permeability measurements, hexaferrites ring-shaped sintered and ring-shaped composites with the hexaferrite powders and epoxi resin were produced. Barium hexaferrite powder (BaM) presented 3.45 kOe of coercivity and the same synthesizing conditions were used in all hexaferrites with dopant atomic fractions of 0,2; 0,4; 0,6; 0,8; and 1,0. In Ti hexaferrites (BaFe12-xTixO19) microstructures there were BaFe2O4, Fe2O3 and Ba3Fe10TiO20 phases and they presented coercivities between 1,53 and 1,04 kOe. Co hexaferrites (BaFe12- xCoxO19) microstructures showed W, Y and Z hexaferrites types phases, with coercivities between 0,70 and 0,21 kOe. In CT hexaferrites (BaFe12-2xCoxTixO19) it was presented CoFe2O4 phase, with coercivities between 0,09 and 1,06 kOe was presented. Most of the pellets sintered in microwave furnace had apparent densities close to those of the pellets sintered in electric furnace and their coercivities were higher or equal. The grains heterogeneity increased with dopant quantities and the Ti microstructures presented more quantity of M type hexaferrites in comparison to other samples. The ring-shaped sintered samples of BaM, Ti and CT hexaferrites showed ferrimagnetic ressonance peaks in 110 MHz and 780 GHz. In Co hexaferrites the presence of hexaferrites different from M type contributed to the different tangent loss in comparison to other hexaferrites. The tangent loss of composites showed the same peaks observed in the ring-shaped sintered samples but with smaller intensities. These composites showed absorption loss up to 20 dB in 12 GHz too.

In this work, five procedures were developed for determination of anions (chloride, sulphate, phosphate and fluoride), with spectrophotometric detection, being four employing a 100-cm optical length flow-cell and one of them employing a cell whith 1 cm optical length. The first procedure employing flow injection analysis with long pathlenght for chloride determination in natural waters was based in the spectrophotometric procedure described in Standard Methods130 in which the reaction between mercury(II) thiocianate and chloride displace the thiocianate ions yielding a reddish complex with iron(III), that was spectrophotometrically monitored at 455 nm. The analytical curve obtained was linear in the chloride concentration range of 1.0 to 50 mg L-1 (r = 0.9989) with a detection limit of 0.2 mg L-1 (3óblank / slope) and a quantification limit of 0.7 mg L-1 (10óblank / slope), RSD < 1.0% (n = 20) and a sampling rate of 72 h-1. The second procedure for chloride determination employed a solid-phase reactor containing silver chloranilate immobilized coupled to the FIA system. The chloride determination is based on the reaction between chloride and silver chloranilate yielding silver chloride, displacing chloranilate ions which were spectrophotometrically detected at 530 nm and the absorbance signals proportional to the chloride concentration. The analytical curve showed a good linearity in the chloride concentration range of 0.5 to 100 mg L-1 (r = 0.9997) with a detection limit of 0.3 mg L-1 (3óblank / slope) and a quantification limit of 0.5 mg L-1 (10óblank / slope), RSD of 1.05% (n = 20) and a sampling rate of 80 h-1. The flow procedure for sulphate determination in natural waters employed a solid-phase reactor containing barium chloranilate immobilized. The determination is based on the reaction between sulphate ions and barium chloranilate yielding barium sulphate, displacing the chloranilate ions that were spectrophotometrically detected at 530 nm. The analytical curve obtained was linear in the sulphate concentration range of 2.5 to 40 mg L-1 ( r = 0.9994) a detection limit of 0.1 mg L-1 (3óblank / slope) and a quantification limit of 0.3 mg L-1 (10óblank / slope), RSD < 1.0% (n = 10) and a sampling rate of 50 h-1. The proposed procedure for phosphate determination in natural waters employing flow injection analysis with long pathlenght spectrophotometry is based on the colorless reaction of iron(III) thiocianate and phosphate ions. Iron(III) reacts with thiocianate yielding FeSCN2+, a reddish complex with maximum absorbance in 468 nm. The phosphate ions in contact with FeSCN2+ yield a colorless complex between iron(III) and phosphate, with non-defined stoichiometry. The decrease of the absorbance signals is proportional to the phosphate concentration in the samples. The analytical curve obtained was linear in the phosphate concentration range of 10 to 100 µg L-1 (r = 0.9996) a detection limit of 4.5 µg L-1 (3óblank / slope) and a quantification limit of 15.6 µg L-1 (10óblank / slope), RSD < 1.0% (n = 10) and a sampling rate of 55 h-1. The procedure for fluoride determination in mineral waters employing a 1-cm optical flow-cell was based on the same procedure for phosphate determination. The reaction between fluoride ions and FeSCN2+ yield the colorless FeF6 3-complex causing an absorbance decrease, proportional to the fluoride concentration in the samples. The analytical curve showed a good linearity for the fluoride concentration range of 0.02 to 5.33 mg L-1 (r = 0.9997) with a detection limit of 5.3 µg L-1 (3óblank / slope) and a quantification limit of 17.6 µg L-1 (10óblank / slope), RSD of 1.9% (n = 20) and a sampling rate of 110 h-1. Results obtained with the proposed procedures were compared with those obtained with the official methods from Standard Methods showing a good agreement at the 95% confidence level.

Background: The term agility has increasingly received attention in Software Engineering, since there is a growing demand for executing and delivering software systems in a shorter and shor ter period of time. Agile software development proposes a rapid and iterative development aiming at meeting all of clients needs and, as a consequence, achieving good results throughout development process. Although this methodology is well-known, it is important to notice that its methods, even the ones which are the most quoted in the scientific literature, do not establish any detailed guidelines so that they can be effectively adopted. Some examples encompass details of activities performed, practices and procedures used and some piece of information which must be documented. However, there are not any case studies which show, practically, the whole pro cess of the adopted method. Aim: This work aimed at contributing in order to achieving improvements in quality of the agile processes by introducing an approach named AQUA - Quality Activities in Agile Context. This approach takes into account th e application of software quality assurance activities such as inspection, test and planning activities which may be used along with any agile method adopted, in the early stag es of requirements elicitation. Method: Only the most quoted methods in the literature were analyzed, from which a generic process was extracted besides a group of artifacts utilized by these methods, supporting, thereby, the definition process of the strategy proposed. Results: This approach was applied by using software requirements developed during a graduate course in Federal University of São Carlos, and the results give insights of its contribution to the improvement in process quality. Conclusion: Although this example had been small, the use of the proposed approach did not make it difficult th e application of the agile method adopted and presented benefits with regard to improvements of process quality.

The anaerobic threshold (AT) is an important parameter for prescription of physical exercise in various clinical conditions, because represent the intensity of effort at which the aerobic metabolism begins to be supplemented by anaerobic metabolism for the production of energy. In this context, different methods to identify AT have been described, for example by analysis of blood lactate and the respiratory gas exchanges, yet such methods require expensive equipment and materials. Low cost non-invasive techniques such as heart rate variability (HRV) have been proposed to determine the AT; however, they are most commonly applied in discontinuous protocols on a cycle ergometer or treadmill. Therefore, the objectives of this study were to evaluate the behavior of HRV and blood lactate during resistance exercise (RE) with increasing resistances at a percentage of one repetition maximum (1RM), and investigate the existence of an aerobic-anaerobic transition point in the metabolism during lower leg exercise in healthy older adults. Secondarily, our objective was to evaluate the relationship between different methods, as well as the degree of concordance between the same. Ten healthy men ranging in age from 60 to 70 years old (mean and SD: 64 ± 4 years, 166 ± 3 cm, 70 ± 7 kg), underwent medical examination, ergonomic testing and laboratory exams (hemogram, triglycerides, total and fractional cholesterols, glycemia and uric acid. The protocol for RE was administered on Leg Press 45° (Pró-Fitness) equipment. The protocol resistance loads used were determined by 1RM test; the volunteer complete one full cycle on the equipment at the maximum resistance load that the volunteer could achieve, and the resistance load increases were calculated from this test value at rates of 10% of 1RM until a 30% increase and then at increments of 5% until exhaustion. At each percentage increase of effort, the volunteer performed 4 minutes of exercise followed a rest interval of 15 minutes. Heart rate was captured throughout the protocol by a Polar Vantage Heart rate monitor connected to a Polar Advantage Interface that transmitted the data in real time to a Soyo Notebook computer. The blood samples were collected before the initial effort and immediately after the end of each resistance load. Blood lactate and HRV were analyzed at rest conditions with the volunteer positioned on the equipment and at each percentage of effort. The indexes utilized for HRV analysis were RMSSD, RMSM, SD1, SD2 and SD1/SD2 ratio. To identify the aerobic-anaerobic transition point, blood lactate concentrations were used (gold standard) as well as SD1 and RMSSD indexes; and these points were denominated as lactate threshold (LT), SD1 threshold (SD1T) and RMSSD threshold (RMSSDT). The level of significance for all statistical tests was set at 5%. The principal result showed that the mean of the RMSSD, RMSM and SD1 indexes reduced significantly at 30% 1RM in relation to the rest condition, and blood lactate presented an exponential increase at 30% 1RM, that was significantly greater in relation to the rest condition at 35%. There was no significant difference in relation to absolute and relative values for resistance loads at which the aerobic-anaerobic transition point was identified (absolute values: LT = 101 ± 32 kg, SD1T = 96 ± 28 kg, RMSSDT = 97 ± 21 kg; Relative values: LT = 30 ± 6%, SD1T = 29 ± 6%, RMSSDT = 29 ± 5%). Additionally, good concordance and good correlation were found between LT and RMSSDT (r = 0.78) and between LT and SD1T (0.81). It can be concluded that the behavior of HRV and blood lactate change markedly at 30% 1RM during resistance exercise on the Leg Press 45°. It was possible at this percentage to identify the aerobic-anaerobic metabolism transition point by blood lactate as well as by HRV in healthy older men.

The modern Zoos are in a continuous improvement for the attendance of your principal functions - leisure, education, conservation and research. The understanding of the relationship among the environmental protection (preservation, conservation and recovery) and the public use of the Zoos for activities recreational or educational has been the administrators' of these institutions great challenge. The present work had as objective the environmental characterization and zoning of the Municipal Zoological Park of Moji Mirim and its immediate surrounding to subsidize your management plan. The Zoological Park environmental characterization was made based on the use of Geographical Information Systems, making possible the elaboration of a georeferenced database and thematic maps of several landscape structural elements (limits, hydrography, road net and land use). These results allowed the proposition of a Zoo s conceptual environmental zoning and for your buffer zone, in terms of the environmental risks resulting from the types and intensities of the immediate surrounding land uses. The environmental zoning constitutes the primary component of a management plan, a public declaration document of the institution manager's of the Zoological Park intentions in the perspective to assure the execution of your functions
