The child s school life with major motor involvement at ordinary school has been discussed together with the possible strategies that can collaborate to the participation and learning of this student. One of the indicated strategies has been the use of assistive technology resources to benefit the performance of the pedagogical tasks and, consequently, help the child s apprenticeship. The literature of this field points the necessity of characterization through scientific studies the assistive technology contributions in the writing and communication tasks inside the classroom. The objective of this study was to identify the effects in assistive technology use in the context of the cerebral palsy student from his perception, his teachers and his tutor. The participants were five students with cerebral palsy, motor levels IV and V according to the Gross Motor Function Classification System for Cerebral Palsy - GMFCS, from ordinary fundamental school for cerebral palsy, users of assistive technology resource in communication and writing school tasks. The teacher and the main tutor of each student were also participants. The instruments used to collect data were the GMFCS, used to classify the motor level of the participants and semi structured interviews realized with the students, teachers and tutors. The data were analyzed starting with the technique of Discourse of the Collective Subject. The study revealed that the children, teachers and tutors who participated recognized the assistive technology resources as an auxiliary resource in production, participation and, consequently benefit the process of these students school life. Notwithstanding, the participants pointed some restrictions brought by the resource and its own context that the use of school inclusion is being realized.

Bioprospective studies of endophytic microorganisms for biotechnological applications are essentials to discovery new substances, which can be used in different areas. Endophytes represent an excellent source of bioactive natural products with chemical structure and biological activities diverses. An endophytic microorganism, isolated from leaves of Prunus spp. (Cerrado of Sao Carlos, SP, Brazil), showed antagonic potential against important pathogen in Public Health. The endophytic microorganism was phenotipic and genetic identified like a Paenibacillus polymyxa and it was given the strain designation RNC-D. The fresh brut extract showed maximum antimicrobial potency of 800 AU.mL-1 against Escherichia coli ATCC 25922 (48 hours of culture) and Staphylococcus aureus ATCC 25923 (120 hours of culture). The bioactive substances contained on extract kept bioactivity after enzymatic assay with proteases and lipase, pH variation from 2.0 to 9.0, thermic treatment using low (-80, - 20 ºC) and high temperatures (100, 121 ºC) against both microorganisms tested. The molecular weight of bioactive substances against E. coli was estimated by ultrafiltration as smaller than 1 kDa, while the bioactive compounds against S. aureus have the molecular weight between 1 and 2 kDa. It was possible to separate the bioactive substances contained in the extract produced by P. polymyxa RNC-D using chromatographic technique (HPLC). Three new molecules, with molecular weight 403, 420 and 425 Da were identified in bioactive peak (eluted in 22% of solution 20 mM TRIS + 1 M NaCl) against E. coli using LC-MS. This research will be continued to determinate the antimicrobial spectrum of the purified molecules, as well as to evaluate the potential application areas.

The elderly still go through physical changes, especially musculoskeletal disorders such as sarcopenia, changes in central and peripheral nervous system, blood hypoperfusion, regenerative changes contributing to atrophy and muscle weakness, undermining the activities of daily living (AVL). The regenerative process happens about the determination, proliferation and differentiation of satellite cells through activation of muscle-specific genetic program, which is regulated by specific transcription factors, known as myogenic regulatory factors (MRFs). But in the elderly because of changes in skeletal muscle-activation of MRFs are inefficient, hindering the process of regeneration. However, recent findings showed very promising results of low laser therapy (LLT) in muscle regeneration, but the effects of this therapy when associated with aging are still unknown. This project aims to evaluate the effects of (LLT), λ = 830nm, the tibial muscle of aged rats after cryolesioning. We used 56 male Wistar rats randomly divided into 4 groups (n = 7) of young rats from 3 months to 4 groups (n = 7) of aged rats, 10 months, divided into control groups (C), groups in which the right Tibialis anterior muscle (TA) was only irradiated (I), groups in which the AT was submitted to cryolesioning (CL) and groups where the TA muscle cryolesioning and was subjected to irradiation (LI). Treatment with the laser model of the DMC, Class 3B, energy of 0.87 J, was performed every 24 h for five consecutive days, with the first application 24 hours after induction of injury. On the sixth day after injury, with the animals anesthetized and the TA muscle was carefully dissected and removed, and then the animals were euthanaziated. We carried out histological analysis of the area of the lesion with toluidine blue, and counting of blood capillaries with hematoxylin-eosin. Through analysis by RT-PCR, it was possible to analyze the expression of MyoD and VEGF genes. The results showed that there was significant increase (p <0.05) of the expression of MyoD gene, VEGF gene and capillary blood count of more prominent in elderly victims and irradiated groups than in the young. Probably the LLT increased the maturation of satellite cells into myoblasts and miotubos, enhancing the regenerative process of aged rats irradiated.

The autism disorder is characterized by a developmental disability witch implies in severe impacts in many areas of development. One of the basic features of the autism is the impairments on language development. Considering that language is symbolic behavior and that stimulus equivalence paradigm allows a specification of symbolic behavior, the present study uses stimulus equivalence paradigm to study equivalence class formation in minimally verbal individuals with autism. In the Study 1, the generalized identity matching was investigated in five individuals with autism. The participants had the verbal and discriminative repertoires assessed by the ABLLS, PPVT-R and ABLA tests. Identity matching tasks were conducted on computer with varied sets of stimuli. Four participants (P2, P3, P4 and P5) mastered the criterion for a variety of sets and demonstrate generalized identity watching. In the Study 2, the four participants whom demonstrate generalized identity matching were taught the visualvisual arbitrary conditional relations AB and CB. All the visual stimuli were abstract forms. Two individuals (P4 and P5) did not achieve the criterion established for the AB relation, despite extensive training. P2 and P3 achieved the baseline relations and equivalence class formation was assessed, showing positive results for both participants. The results obtained show how programmed teaching promotes the acquirement of conditional discriminations and the demonstration of symbolic behavior by autistic individuals with minimal verbal repertoires.

Through the investigation of the English teaching/learning process in two third age universities and through the presentation of the profile of these age group learners, we aim to provide contributions for further developing materials for foreign language teaching which are focused on the referred age group. Bearing in mind that this issue demands knowledge not only of the teaching/learning process, but also the aspects related to the alterations which occur during the ageing process, the theoretical support of this research relies on the Applied Linguistics and Gerontology knowledge. The analyzed data show some aspects to be considered during the development and use of such classroom materials. These aspects are: the loss of visual and hearing acuity, the memory ability of these learners and beliefs related to this subject, the question of the elderly language, the presence of yesterday in their speech, among other factors which are related to ageing process. Besides these aspects, we stress the benefits of a social and cognitively motivating environment for the development and maintenance of the elderly physical and mental abilities. Another fact to be considered is the necessity of overcoming possible stereotyped or prejudiced ideas, or even images of the elderly and the old age which are currently used in society, mainly when it refers to the process of knowledge acquisition and to the foreign language teaching/learning process. This research results in proposals to the use and development of didactic materials for foreign language to the third age students.

A performance measurement system is an essential element of management system of any organization to support the achievement of its objectives. Major changes in financial markets, customers' demands, and the social environment, it is vital to the organizations to implement an effective performance measurement system capable to keep update to such changes. The response to these changes lead to implementation of new management practices which changes the performance measurement system to other maturity levels in terms of performance measures, infra-structure (gathering, storing, sorting, analyzing, interpreting and disseminating data), usage, and people. Hence, this dissertation aimed to investigate empirically what are the dimensions of performance measurement system maturity in organizations which implemented the State of São Paulo Quality Award. Two case study were carried out in companies which are winners of such quality award. The main empirical findings point out to the following dimensions of performance measurement system maturity: planning, performance measures, infra-structure, people, usage, and information technology. Those dimensions of performance measurement system have changed in the two studied companies after the implementation of excellence model of the State of São Paulo Quality Award with the introduction of new management practices.

Polyaniline (PANI) chemical synthesis was monitored in situ by means of electrochemical impedance, open circuit potential (Voc) and mass variation. We verify that the final properties of the polymer could be practically defined after inflection point in the potential profile. The impedance data were decisive to understand this behavior, showing only a small change after inflection point. Impedance results and mass variations during the synthesis contributed to understand the induction mechanisms that occur in the initial stages of the polymerization process. Also, it was performed an investigation on the influence of different variables (temperature, monomer:oxidant molar ratio, oxidant, pH value, use of inert salts at high concentrations) in the PANI chemical synthesis process as well as in its physicochemical properties. In this work, it was estimated the characteristic points of PANI through the Voc measurements during the chemical synthesis, based on an experimental design methodology. This methodology allowed an efficient mapping of PANI synthesis process as well as its interactions with each variable previously described. The results indicated that the oxidant employed in the synthesis influences in the final chemical and physical properties of this polymer. The studies performed on the final properties of PANI were the degree of oxidation and electric resistivity. Moreover, the yield the degree of polymerization was also evaluated. The experimental design methodology was also used in order to understand the influence of the preparation conditions on the final properties of the blends in poly(acrylonitrile-butadiene-styrene) (ABS) and polyaniline obtained by the co-dissolving components in a common organic solvent. The variables evaluated were the PANI content in the blend, m-cresol:chloroform rate (solvent ratio), dopant (DBSA or CSA) and acrylonitrile content in the ABS. The results showed that these variables are able to change significantly the flexibility and electric conductivity of the blends. On the other hand, the dopant used mainly influences in the conductivity, suggesting that the DBSA is the better for the development of PANI/ABS blends more conductive. After better prepare conditions of the blends, the percolation threshold was established at around 3 wt% of PANI, forming a flexible blend with conductivity of approximately 3 S.cm-1. The optical properties of the blend films were characterized by UV Vis-NIR. The conduction mechanisms of the blends were investigated using a dc electric conductivity in the range from 80 to 320 K. Using the Mott s theory, it was found that the conductivity in the blends is a threedimensional variable range hopping mechanism. The Mott s temperature values, density of states at the Fermi energy, average hopping distance and barrier height for the blends were calculated and discussed in this work. Also, two possible technological applications were proposed to the PANI/ABS system, including: composite varistors and antistatic or electromagnetic protection of electronic devices. The varistors were prepared with 30% of PANI, which showed a low rupture voltage at around 10 V and a non linearity coefficient of approximately 9,2. On the paint shape and when deposited on cardboard, this material can be employed as protector system of electronic devices. Another important characteristic is the conductivity of this material, which is controlled by the number of paint layers deposited on the cardboard.

Reverse logistics has conquered more importance and space in the companies logistics operation, mainly for its economic potential, but also for the change in the customers consumption culture and for the increase of the importance of environmental preservation. However, the lack of studies in this direction makes it difficult to visualize the advantages of the reverse logistics application. In such a way, the objective of this study is to understand the reverse flow configuration, as well as its critical points, the inherent performance measures to the process and the strategic use of after-sale reverse logistics to the reverse flows management in meat and dairy food distribution channels. Qualitative studies have been developed, in France and Brazil, with the multiple-cases study methodology. In France, two dairy manufacturers and a food retailer have been interviewed and, in Brazil, four meat and dairy manufacturers and three food retailers have been interviewed. In the thesis, the results have been presented and analyzed for each country, and they also have been compared with literature. From the results analysis, it was possible to identify that after-sale reverse logistics has a strategic use for the industrial companies. The main processes of reverse logistics used by the studied companies are the resale in original market, the resale in other markets, the landfill and the loads consolidation for manufacturer collection. The gatekeeping (mainly for the retail) and the existence of collaborative relations between the companies have been considered the most critical factors to reverse logistics management. However, the brazilian companies have affirmed that the retailers uses the coercive power, mainly, to impose to the industry a way to manage the reverse flows. Moreover, the performance measures used by the manufacturers and retail companies in the meat and dairy food distribution channel have been shown. The most used performance measures are: total reverse logistics cost, cost of returned merchandises, cost of deteriorated products, cost of pallet and packing returns, perfect order fulfillment, return percentage and return reason. With this analysis, it was possible to provide recommendations and reference parameters for reverse logistics of perishable food as the derivatives of meats and milk.

Dementia involves the loss of cognitive functions, interfering with the execution of even the most basic tasks of everyday life. Family eldercare providers are central figures in guaranteeing the wellbeing of their elderly relatives who develop dementia. However, when such a person becomes dependent on other family members, in addition to an increase in the caregiver s domestic chores, the behavior problems that arise can have a negative impact when caregivers are not well prepared for this situation, making the caregivers more susceptible to depression and contributing to the deterioration of their own physical and psychological wellbeing, making the caregiving context even more difficult. The objective of this study was to analyze the effects of psycho-educational support groups (PEG) for people caring for a relative with Alzheimer s disease (AD), associated with individual, home visits that were either training-oriented (Experimental Group EG) or listening-oriented (Control Group CG) in nature, with respect to the participants perceptions of burden, depressive symptoms and quality of life. The nine participants were randomly assigned to either the EG and CG. The EG participants received encouragement and assistance in operationalizing the concepts learned in the PEG, which addressed strategies for managing stress and depression and provided training in some of the social skills that are useful in establishing new routines (praise, constructive criticism, and asking for help). The CG received visits of the same duration, bus focused only on listening. The participants were interviewed about their situation, but did not receive individual assistance in operationalizing the strategies presented in the PEG. At the end of the first phase of the intervention, each group received the other type of home-based intervention. The data were analyzed using nonparametric tests (Mann-Whitney and Wilcoxon). The psycho-educational groups were effective in transmitting information, but did not reduce the caregivers perceptions of burden, reporting of depressive symptoms or change their quality of life ratings. After the caregivers received the training-oriented home visits (TV), their perceptions of burden significantly decreased and their quality of life ratings increased. The listeningbased visits had no significant effects on the caregivers. Six months later, an analysis of the follow-up measures indicate that improvements in perceptions of burden, frequency of depressive symptoms and quality of life scores were maintained by those who experienced the PEG coupled with TV. In conclusion, it is clear that professionals who offer orientation programs for family members caring for elderly relatives who have AD should further invest in evaluating the influence of home visits that focus on assisting these caregivers in adjusting their managerial and coping strategies, so as to increase our knowledge of how to blend group-based and individual psycho-educational supports in order to maximize the effects of such interventions.

The Weibull distribuition is a common initial choice for modeling data with monotone hazard rates. However, such distribution fails to provide a reasonable parametric _t when the hazard function is unimodal or bathtub-shaped. In this context, Cooray (2006) proposed a generalization of the Weibull family by considering the distributions of the odds of Weibull and inverse Weibull families, referred as the odd Weibull family which is not just useful for modeling unimodal and bathtub-shaped hazards, but it is also convenient for testing goodness-of-_t of Weibull and inverse Weibull as submodels. In this project we have systematically studied the odd Weibull family along with its properties, showing motivations for its utilization, inserting covariates in the model, pointing out some troubles associated with the maximum likelihood estimation and proposing interval estimation and hypothesis test construction methodologies for the model parameters. We have also compared resampling results with asymptotic ones. Coverage probability from proposed con_dence intervals and size and power of considered hypothesis tests were both analyzed as well via Monte Carlo simulation. Furthermore, we have proposed a Bayesian estimation methodology for the model parameters based in Monte Carlo Markov Chain (MCMC) simulation techniques.

Basic and molecular cytogenetic studies were carried out in a few fish species from family Parodontidae: Apareiodon ibitiensis, A. piracicabae, A. affinis, A. vladii, Apareiodon sp. Parodon nasus and Parodon hilarii. All were collected in distinct hydrographic basins, with emphasis in a river transposition area, more specifically of the Piumhi River. Apareiodon. ibitiensis from the Upper Paraná River and Apareiodon sp. A from the São Francisco River presented the same chromosomal characteristics, as also observed in A. piracicabae in relation to Apareiodon sp. B. The presence of simple sex chromosomes of the ZZ/ZW type was verified in A. ibitiensis and Apareiodon sp., where the presence of the heterochromatin that originated the W chromosome was identified through C-band staining with propidium iodide. Fluorescent in situ hybridizations (FISH) with 18S and 5S ribosomal DNAs were performed in A. affinis, A. piracicabae and A. ibitiensis, resulting in a single chromosome pair marked with 5S rDNA in the three species, all in distinct chromosome pairs. The 18S rDNA is also present in one pair in A. affinis and A. piracicabae, but was polymeric among A. ibitiensis populations. While the 18S rDNA is more conserved in the Parodontidae species, the 5S rDNA may be considered a cytotaxonomical character for the group. FISH with pPh2004 satellite DNA isolated from P. hilarii was also performed in A. piracicabae, A. ibitiensis, A. vladii, A. affinis, Apareiodon sp. and P. nasus, but markings were only found in P. nasus. and A. affinis. When compared to other species where FISH with pPh2004 was carried out, two groups form: 1) the presence of this DNA in all the Parodon species, and 2) the absence in almost of the analyzed Apareiodon species, suggesting the maintenance of these genera. After the chromosomal characterization and confirmation of the species Apareiodon ibitiensis and Apareiodon piracicabae, besides Parodon nasus in distinct localities of the São Francisco River basin (regions of the Três Marias and the Piumhi River transposition), a cytogenetic tracking of the Parodontidae species in this hydrographic basin was made possible, which can be justified through natural (Piumhi Pantanal) and anthropogenic (Piumhi River transposition) connections between the Upper Paraná and the São Francisco River basins. Besides the Parodontidae species, Gymnotiformes species (Eigenamnnia virescens and Gymnotus sylvius) also described for the Upper Paraná basin are distributed in the São Francisco basin, and the transfer probably occurred through the Pantanal or the transposition. Cytogenetic analyses with a larger number of tools in the family Parodontidae was important for a better understanding of the evolution of this fish group, besides having been an important tool in the comparison of allopatric Parodontidae, Gymnotidae and Sternopigydae species present in the Upper Paraná and São Francisco River basins.

The city of São Carlos, of medium size of São Paulo State, can be considered as representative of the Brazilian Southeast area, with agricultural activities practically equivalent to the industrial ones. As part of that profile, it possesses a series of sources of atmospheric pollution that include a considerable fleet of vehicles, agricultural burns and several industrial emissions. The time evolution of this environmental pollution has been reason of concern, once it can cause damages to the human health and to the environment. The present work studied these time characteristics, specifically for the case of particulate matter (PM) suspended in the atmosphere, from experimental data and through statistical models. The concentrations of PM10, PM2.5 and PM10-2.5 in the city of São Carlos were collected and analyzed. The period of study comprises the years from 1997 to 2006 for PM10 and from 2001 to 2006 for PM2,5 and PM10-2,5. Monthly averages were used for obtaining the models and the 30 (thirty) or 6 (six) final data were used for the validation of the forecast. The selection of the best model was made considering the smallest value of AIC (Akaike Information Criterion), through the successive variation of the parameters. Of the 10 models with smaller value of AIC, was chosen the one of smaller value and other with a smaller number of parameters. In the statistical analysis, the models that did not comply with the requirements of the Shapiro-Wilk tests (normality) and of steadiness were eliminated. In the three cases the model SARIMA represented the groups of studied data better, when compared with the Holt-Winters correlation. The model found for the series of data of PM10, was the SARIMA(1,0,0)×(1,0,1)6. In the second case, the concentration of PM2.5 the best model was the SARIMA(2,1,3)×(1,0,1)6. In the third case, the concentration of PM10-2.5, the best model was the SARIMA(2,0,2)×(1,0,0)6.

Animal-assisted therapy (AAT) is used by health professionals to promote emotional, affectivity, cognitive, social and phisical development by animal-human interaction. AAT can use different animals and be indicated for several needs, as Mental Deficiency (MD). The objective of this study was to verify the effect of animals intervention (AAT) in the psychomotor development of children with MD. The used drawing was the experimental type with control groups. Twelve children ranging from 9 to 13 years of age were divided into two groups, separate in two groups at random, control group (CG) and experimental group (EG), that frequent the same specialized school institution. The established criteria for formation of the groups were: diagnosis of MD, the same economic level and do not present animals fear. The psychomotor development was evaluated by the following instruments: Motor evaluation of Rosa Neto; structured interview for survey of the participants' emotional aspects; structured interview for survey of the psychomotor and emotional aspects directed to the responsible individuals; and field diary. The procedure for the data collection was developed in the following stages: a- groups formation (experimental group-animals and professional intervention A group; and control group: 1- professional intervention without animals B group; 2- without intervention- C group); b- initial evaluation (motor evaluation and interviews with participants and responsible individuals from the three groups); cintervention with post-fact recordings (field diary) and d- final evaluation (motor revaluation and interviews with participants and responsible individuals). AAT was executed with two small dogs. The data were analyzed in a quantitative way and represented in graphs and tables. For the qualitative analysis, it was accomplished through the recordings obtained in the field diary and analysis of the answers of the interviews. The data were analyzed in an individual way and a comparison between control and experimental groups was made. It was concluded that AAT brings benefits to individuals with MD regarding the motor development, motivation and care with living beings.

The employment of flow injection systems to determination of N-acetylcysteine, captopril, dipyrone and fluoxetine hydrochloride in pharmaceutical formulations was investigated. The N-acetylcysteine was determinated employing a solid-phase reactor containing Zn3(PO4)2 immobilized in a polyester resin coupled to a flow injection system. The procedure was based on the chelation of Zn(II) ions with N-acetylcysteine in the solid-phase reactor, with consequent releasing of the complex Zn(II)-N-acetylcysteine of the reactor, this complex reacted with alizarin red S (VA) in borate buffer pH 9.0 generating the complex Zn(VA-BO3)3 which absorbance was measured spectrophotometrically at 540 nm. The second developed procedure was the determination of captopril (CAP) in pharmaceutical formulations employing a solid-phase reactor containing silver chrolanilate (Ag2C6Cl2O4) immobilized in a polyester resin. In this system occured the precipitation reaction of captopril with the Ag(I), producing in the reactor an insoluble salt between the CAP and the Ag(I) due to the lower solubility of the formed salt related to Ag2C6Cl2O4. After the formation of the insoluble salt in the reactor occured the releasing of chloranilate anion, C6Cl2O4 2-, that reacted with the Fe(III) producing the complex FeC6Cl2O4 + which was monitored spectrophotometrically at 528 nm. In another procedure, the N-acetylcysteine and captopril were determined separately in a flow injection system through the on-line of the Prussian blue formation. In this procedure, the N-acetylcysteine or the captopril were oxidized by Fe(III), producing Fe(II) that reacted with hexacyanoferrate(III) in a point of flow system, generating the Prussian blue (Fe4[Fe(CN)6]3), that was monitored spectrophotometrically at 700 nm. It was also proposed a flow injection system with merging zones and intermittent flow with turbidimetric detection to determination of fluoxetine hydrochloride in pharmaceuticals. This system was based on the formation of an insoluble salt (AgCl(s)) between the AgNO3 and the chloride of the hydrochloride of the fluoxetine molecule that was turbidimetrically detected at 420 nm. Finally, two procedures were developed employing a flow injection system to determination of dipyrone in pharmaceuticals using Fe(III) as chromogenic reagent. In the first procedure, it was employed an analytical microsystem constructed with LTCC and in the second one, it was used a flow injection system with merging zones without the use of microsystem. In these systems, occured the formation on-line of an blue chromophore between Fe(III) and the dipyrone that was monitored spectrophotometrically at 622 nm.

Children who do not have a positive, secure and affectionate relationship with their fathers, or whose fathers use rigid disciplinary practices, provide inadequate supervision and have infrequent or poor quality interactions with their children, are at greater risk for developing socio-emotional problems and for remaining at lower levels of academic achievement. However, the majority of fathers have little understanding of the importance of their involvement with their children. As such, the primary objective of this study was to evaluate a program designed to improve father involvement and to stimulate the use of parenting practices that foster children s pro-academic behaviors, using measures obtained before and after the intervention as well as one year later (follow-up). The specific objectives included: (a) the comparison of indicators of work conditions, personal and family wellbeing, father involvement and the parents social skills on the pre, post and follow-up tests among the Experimental Group 1 (EG1 composed of fathers who were randomly selected to participate in the intervention program), Experimental Group 2 (EG2 composed of randomly selected mothers who participated in the intervention program) and a Control Group (the remaining, waitlisted parents); (b) comparison of the academic achievement, self concept, behavior problems and social skills of their children at the time of the pre, post and follow-up tests, for those in the EG1, EG2 and CG; (c) examination of the strength of the correlations among these variables, and (d) analysis of parent evaluations of the topics that were addressed and the procedures used in the intervention program. At the times of the pre and post-tests, parent participants included 97 father-mother pairs (29 in the EG1, 34 in the EG2 and 34 in the CG) and 82 of these father-mother pairs at the time of the follow-up tests (24 in the EG1, 29 in the EG2 and 27 in the CG). At the time of the pre and post-tests, data were also obtained from 99 children (there were two sets of twins) 29 from the EG1, 36 from the EG2 and 34 from the CG. At the time of the pretest, these children were eight years old, on average, and 78,8% of them were in Grade 2 while the others were in Grade 1. At the time of the follow-up tests, 84 of these children were re-evaluated (24 from the EG1, 31 from the EG2 and 27 from the CG). In addition, in the first year of the study, 20 teachers (85% of whom had completed university studies) participated in the pre and pos-test phases and a second set of 12 teachers (all of whom had completed university studies) participated in the follow-up phase, given that the children had advanced to the next grade between the post-test and the follow-up. Data were collected with children from three different, public elementary-schools. The intervention program was conducted with the parents during 12 weekly sessions that were 90 120 minutes long, with the GE1 fathers and GE2 mothers. To address the objectives of this study: (a) the parents evaluated their work conditions, their personal and family wellbeing and their social skills repertoire; (b) both parents and their child evaluated the father s level of involvement as a parent; (c) the children s academic achievement, self concept and social skills were assessed; (d) both parents evaluated their child s behavior problems and social skills repertoire; (e) the teachers evaluated the children s academic achievement, behavior problems and social skills, and (f) the fathers from the EG1 and the mothers from the EG2 evaluated the intervention program. Statistical testes (ANOVA and MANOVA) were used to compare the data obtained in the three different phases of the study, for each of the three different types of informants (parents, children and teachers). Pearson correlations were used to examine the bivariate relationships among these variables. With respect to the first objective, comparisons of the results on the pre and post-intervention tests revealed that the fathers in the EG1 were significantly less stressed and there was a significant decrease in the number of disagreeable behaviors that their children presented; both the GE1 and GE2 fathers presented greater satisfaction with respect to their family-role performance, higher frequency of communication with their child, greater frequency of participation in school, cultural and leisure activities with their child, greater participation in school meetings concerning their child, more frequent contact with their child s teacher and listed a greater number of their child s behaviors that pleased them. In terms of the children s gains, a comparison of the pre and post-test results indicate that children in the EG1 presented: (a) higher scores on the Academic Achievement Test (AAT) with respect to the reading sub-test and their overall score, along with higher teacher evaluations of their academic performance; (b) a lower number of internalizing behavior problems (according to their fathers), externalizing and total problems (according to both parents); (c) social skills that were more adequate with respect to self control (for both self and father ratings) and self defense (according to the teachers), and (d) more positive teacher evaluations, across various indicators. Similarly, in comparison with the pre-test, on the post-test, children in the EG2 presented: (a) higher scores on the Academic Achievement Test (AAT) with respect to the reading sub-test and their overall score, along with higher teacher evaluations of their academic performance; (b) a lower number of externalizing and total problems (according to both parents); (c) social skills that were more adequate with respect to Cooperativeness and Self control (according to their fathers) Assertiveness in their coping strategies (according to their mothers), and Cooperation with peers (according to the teachers), and (d) more positive teacher evaluations, across various indicators. The majority of the gains obtained by the fathers and their children by the end of the intervention program were maintained or further improved at the time of the follow-up tests, with the exception of the children s self-evaluations of their social skills on the Self control factor, for which there was a significant decline between the post-test and follow-up test. With respect to the third objective, father involvement was significantly correlated with the children s academic performance, self concept, externalizing behavior problems and social skills, and measures involving the children were significantly inter-correlated. Finally, in general, the intervention program helped the fathers (EG1) and mothers (EG2) in bringing up their children. For example, some parents (22,2%) commented that it became easier for them to deal with the difficulties of parenting, while others (19%) were better able to handle their children s behavior problems, occurring either at home or at school. The parents attributed various important contributions to the intervention program: 27% changed their parenting behaviors, 19% were giving greater importance to their child s opinions and 15.9% commented that their child was more obedient. With respect to the parents acquisition of new social educational skills, 31.7% said that they learned about the importance of respecting their child s opinion and 30.2% said that they learned to set limits for their children. These results indicate the importance of educational interventions for maximizing parental involvement and, as a consequence, improving their children s social emotional development and classroom behavior.

In this work, we studied the effects of the promoters of support (ZrO2, La2O3, CeO2, CeO2-ZrO2, CeO2-ZrO2-La2O3 and La2O3) in the nickel catalysts supported on γ-Al2O3 were studied. The supports were prepared by wet impregnation on γ- Al2O3 (Alfa Aesar) with 10% by weight of oxides of cerium, zirconium, lanthanum, ceria-zirconia, ceria-lanthanum and lanthanum-zirconium. The addition of nickel was performed by impregnation of the supports using an aqueous solution of Ni(NO3)2.6H2O (Fluka), followed by drying at 373 K for 24 hours and calcined in synthetic air (80 ml / min) at 823 K for 5 h. The samples were characterized by dispersive spectroscopy X-ray (EDX), analysis of BET, X-ray diffraction (XRD), temperature programmed reduction (TPR), temperature programmed Desorption (TPD), and temperature programmed oxidation (TPO). The catalysts were studied for steam reforming, partial oxidation and oxidative reforming of methane. For steam reforming, the catalysts that have two promoters and the catalyst NiLaAl presented the highest catalytic activities. In the partial oxidation the values of conversion of methane produced by different catalysts are similar. In the oxidative reforming the catalysts that have only one type of promoter and the catalyst NiCeLaAl, above 500 º C showed the best catalytic performance.

The aim of this work is to give some suficient conditions for the existence and multiplicity of the solutions for a class of elliptic problems with sign-changing weight function in unbounded domains, using for this variational techniques. Specifically, in the semilinear case we use the minimization arguments on the Nehari manifold. For the quasilinear case, as in the scalar case as in the system, we use the minimization arguments and a variant of the mountain pass Theorem without the Palais-Smale condition.
