    Let G be a finite group acting freely in a Hausdorff paracompact topological space X and let Y be a k-dimensional metrizable space (or k-dimensional CW-complex). In this work, by using the genus of X; gen(X;G), we prove coincidence theorems for maps f : X ! Y . Such theorems generalize the main theorem proved by Aarts, Fokkink and Vermeer in [2]. Moreover, by using the Volovikov index defined in [39], we prove a Borsuk- Ulam theorem for compact Lie groups, which generalizes the main result proved by Biasi and Mattos in [7, 12].

    Alzheimer's disease generates dependency requiring care usually provided by a relative. With the evolution of the disease, there are physical exhaustion, emotional, social and even financial support for this family. This work aimed to study primary family caregivers of patients with Alzheimer's Disease. Data were collected socio-demographic profile, apply to the inventory of the Zarit Burden Scale and Quality of Life in Alzheimer's disease - the version of care. Participated 156 caregivers, with most middle-aged women, daughters, with more than eight years of study, income of four minimum wages, providing care for up to 36 months carrier with whom the majority live and not counting with the aid of caregivers formal. The majority reported health problems, and used public health services and private. Most had mild to moderate burden and quality of life scored around good. The correlation between burden and quality of life and moderately negative (r = -0.598, p <0.000) suggests that the higher the burden the worse the quality of life.

    This work consists in building, implementing and evaluating a Virtual learning Environment (VLE) as a tool to support the teaching of physics with traditional methodology, in high school, using the Moodle softares package. The environment has been structured to have the student making use of VLE during the whole school year, with the contents distributed in cycles for the three series as follows: Kinematics, Dynamics, Hydrostatics, Thermophysics, Electrostatics and Electrodynamics. The cycles have a basic structure formed by a study guides , a summary text with exercises to assimilation and deepening of contents, virtual labs, simulators and evaluation questionnaires . The use of VLE proved to be an organizer and facillitator of the study and mainly a motivation tool for students that had increased the time of study and interaction with the teacher. The activities were developed in bimodal form, where first the instructor gives a lecture and after the students perform activities at home, which allows the instructor resuming and redirecting the contents according to the performance of the students in the VLE. The increase of motivation for better learning, verified through the completion of the tasks proposed, was confirmed by results obtained in some tests answered by volunteer students.The VLE ia available at www.escolananet.com and and hosted at the site of the Graduate Program in Teaching of Exact Sciences of UFSCar.(http://www.ppgece.ufscar.br/.)

    In this work, we study the result of well-posedness for the cubic wave equation u + u3 = 0 in R3, due to H. Bahouri e J.-Y. Chemin, where the Cauchy data is in the Homogeneous Sobolev space ̇H3/4(R3) × ̇H−1/4(R3). The proof relies on nonlinear in- terpolation method, the Bony's decomposition and the logarithmic Strichartz estimates, as formulated in the Littlewood-Paley Theory

    The organism Planktothrix agardhii belongs to one of the two most abundant genera in the world among the phytoplankton (the other is Microcystis sp.). Nevertheless, the genus Planktothrix is potentially toxic, producing microcystins and anotoxinas, which makes relevant knowledge of the biology of species that produce large biomass, as the case of P. agardhii, and the relationships with the communities that coexist with them. Knowledge of the composition of EPS was fundamental to the understanding of possible correlation with bacteria based on the use of EPS as a substrate. The EPS excreted by P. agardhii grown in axenic culture is a heteropolymer rich in glucose (17.04%), whose composition also have the monosaccharides: glucuronic acid 13.78%, 12.65% of fucose, from 10.95 n-acetyl galactosamine, 10.48% n-acetyl glucosamine, 7.78% of rhamnose, galactose 7.04%, 4.89% arabinose and 15.39% from other types of sugars. EPS is composed of only one fraction slightly acidic. The degradation of EPS by the bacteria in natural population of Barra Bonita reservoir started at 12 hours and was totally consumed on the 31st day of exposure. The degradation of the polysaccharide followed by gas chromatography showed a quick decrease in the amount of glucose followed by an increase in the same after the 12th day. As for glucuronic acid occurs primarily an increase in concentration, followed by a sharp decline after the 12th day. The other monosaccharides present degradation to a minimum concentration or were completely exhausted.

    Expectations on inclusive education have demanded the creation of new staff roles in schools. In an inclusive school environment, an important aspect of the role of educational psychologists that seems to be a promising picture in this profession is to promote and develop strategies and guidelines for consideration and adoption of the Collaborative Consultation in the Schools, building partnership with teachers and families. The aim of this study was to evaluate the effects of a preventive intervention program, based in the principles of the Collaborative Consultation in Schools and the Positive Behavior Support models, designed to prevent and minimize behavior problems. The study has been conducted in three 1st. grade classrooms in a public elementary school located within the state of São Paulo, assessing three teachers of these classrooms, fifty-five pupils, and eighteen families participation. The study has been carried out in four phases. In Phase 1, the ethical procedures were followed to contact the school. In Phase 2 at the pre-test stage, participating families were asked to complete the Parenting Styles Inventory (PSI) instruments as well as the teachers were requested to complete the Child and Youth Behavior Inventory (6-18 years)/Teacher Report Form (TRF). In Phase 3, the preventive intervention program was implemented, targeting and focusing on teachers, pupils, and participating families. Finally, in Phase 4, at post-test stage, both instruments were repeated and moreover individual focal groups meetings were held with teachers and families in order to examine the social validity of the study as well as it was gathered qualitative data to analyze the effects of the previously applied intervention program. To assess the impact of the intervention, MANOVA test was applied to the results obtained with the PSI and the TRF. Regarding parenting styles, there was a statistically significant increase in the parenting style index, with respect to the positive monitoring and moral behavior, and a statistically significant decrease in relaxed discipline, and in the negative monitoring. In relation to student behavior, according to reports from teachers, there was a statistically significant decrease either in internalizing or externalizing problems, or in total problems. The results of the focal group meetings held with the families provided information about favorable and unfavorable aspects of the intervention; it was noticed positive changes in child and family behavior; it was evaluated the position of a psychologist within the school. Finally, the meetings with the teachers allowed to gather information about the characteristics of the collaboration that were included in the developed intervention; favorable and unfavorable aspects of the intervention; positive changes related to student behavior at school and their quality of life; degree of applicability of the developed strategies; evaluation of the position of a psychologist at the school.

    Manual preference has been regarded as derived from innate performance advantage of one hand over the other. The main purpose of this work was to investigate the relationship between manual preference and intermanual performance asymmetry on a task of reaching for static targets in five-month-old infants. Secondary purposes were to assess the effects of spatial target position and gender on manual preference, and the relationship between the infants‟ and the parents‟ manual preference. Manual preference was evaluated through frequency of right- and left-handed reaching toward targets at right, midline and left positions, regarding the midsagittal plane of the infant‟s body. Intermanual asymmetry was assessed through kinematic analysis of reaching toward the target at the midline position. Dependent variables were the following: movement time, movement straightness, number of movement units, median velocity, peak velocity, and deceleration time. Analysis of manual preference indicated similar frequency of rightand left-handed reaching at midline and ipsilateral reaching toward lateral targets. Analysis of manual preference regarding toy positions indicated the equivalence between the incidence of infants presenting right and left manual preference. Kinematic analysis showed similar patterns of reaching between the right and left hands, except for deceleration time. Manual preference was not correlated with performance asymmetry. These results suggest that early manual preference in reaching does not derive from a superior capacity of control of one hand over the other. Manual preference was not significantly different between males and females, and it was not correlated with parents‟ manual preference. Results are discussed in terms of environmental versus genetic factors associated with formation of manual preference.

    This paper presents a study on the vulnerability in terms of soil loss in a hydrographic basin, scale 1:50,000. Its main purpose is to draw up a vulnerability chart to erosion based on the themes of geomorphology, geology, soil, vegetation, land use and climate. The study area comprises the hydrographic basin of the Ribeirão do Pântano stream, a sub-basin of the Mogi-Guaçu river, which encompasses parts of the municipalities of Analândia, Descalvado and São Carlos, located in the center of the State of São Paulo. The methodological approach proposed by Crepani at al 2001, founded on the concept of Tricart's Ecodynamics, was employed to achieve the objectives of this research. The knowledge on the areas vulnerable to erosion is very important in order to elaborate a proper environmental planning, to control the occupation of the basin soil and to prevent the occurrence of erosion and soil loss in the studied area.

    The FAU zeolite was obtained using different amounts of water. Both at higher levels as the lowest amount of water the intensities of the diffraction peaks are less intense. The results of physisorption of these samples suggest the presence of material not yet crystallized in this product. The scanning micrographs show large spherical particles with apparent roughness, suggesting the formation of aggregates of smaller particles. For transmission electron microscopy the results show very dense clusters, with indicative that the particles are very cohesive. The crystallization curve shows that the stabilization of the phase occurs at 8 h of synthesis at 100 ° C, be interesting to work on shorter times to prevent the growth of particles. The aging of the mixture facilitated the crystallization of the material by decreasing the induction time and particle size. In high alkalinity can be observed a decrease in the intensity of diffraction peaks and size of particles observed by SEM. Long crystallization times produce materials with high external area, about 40% higher than a commercial sample. The variation of aging time of the samples with high alkalinity shows that with three days are obtained clusters of about 100 nm are formed by crystals even smaller. Therefore, was developed a method to obtain nanocrystals of zeolite FAU, without the presence of template and using silica and alumina sources with reduced cost.

    For that management of the hazardous wastes be held of correct environmental way, technical and administrative arrangements should be implemented, involving the prevention and effective control of generation until its final disposition. Considering the importance and complexity of the wastes management at universities, the objective of this work is to make a diagnosis and analysis of the questions involving dangerous wastes generated by the Centre for Agrarian Sciences - UFSCar campus from Araras city, in order to propose management of these wastes, with the aim of promoting reduction and/or elimination of the environment impact caused by improper discard, based on necessities and particularities of UFSCar campus and literature related. Were discussed some important concepts about thematic of wastes in the university, as well as the best ways of management of hazardous wastes in theses institutions. Aiming to set particularities of the campus from Araras city was accomplished the diagnose and characterization of the dangerous wastes by applying a semi-structured interview with the manager staff of the wastes sectors. Due the diversity of labs, 116 differents itens of wastes are generated, these wastes can be separated in categories and they present different degree of risk. However, in the campus from Araras city are storaged more than a half (54,4%) of these wastes, considered dangerous, the remainder part of it, is discard of wrong way. The data about waste treatment, show that just 8,5 liters per month of wastes perform some treatment, ie, less than 2% of the total generated. Fortunately, it is feasible that this reality can be changed leading the college to a correct control of their wastes. However it is necessary to create a recycling conscience and informations, that are able to change the complex circunstances present in the university.

    The incorporation of conducting polymer into a conventional polymer matrix has received considerable attention in the last decade because of the possibility of combining the good processability and mechanical performance of the conventional polymer with the electrical optical properties of conducting polymer. Among conducting polymers, polyaniline (PANI) and its derivatives has been extensively used because of the low cost of raw material, ease of synthesis and environmental stability. The main objective of this study was to develop a sensor for electronic tongue, from thin films of blends of polyurethane with POMA on interdigitated electrodes produced by spin-coating technique, under optimized conditions, and check the electrical behavior of the sensors in states doped. Films PUR mixture with POMA, although they may have less sensitivity to the substances found in the analyte than the nano-structured films, they may have better adherence and therefore be used to analyze substances with which the nano-structured films would not be possible. Films mixture of polyurethane derived from castor oil (PUR) and POMA were obtained by the casting (free standing) and also on interdigitated electrodes by the method of spin coating. The films were characterized using the techniques of UV-Vis-Nir, thermo-dynamic-mechanical analysis (DMTA), thermogravimetric analysis (TGA), stress-strain and optical microscopy. The values of modulus of elasticity of the PUR solvent chloroform (PUR-Clo) for the mixture of PUR/POMA (m/m) 50/50 had values of 0.3 GPa and 4.1 GPa, respectively. With the incorporation of 10% of POMA in the PUR glass transition temperature (Tg) of the films increased from 67 to 137oC, respectively. For the analysis done by DMA, the films with 30, 40 and 50% of POMA in PUR, confirmed the presence of crosslinking between the polymers, Mc, values of 195, 322 and 517 mol/m3, respectively. The films doped with NH4OH and HCl have better response capacitive and resistive to various analytes analyzed in the frequency range 1-105 Hz Thus, the sensors doped and dedoped can be used as an identifier of fingerprint detection of substances in different concentrations.

    Catalysts obtained by thermal decomposition of the precursors with hydrotalcite-like structure [Mg1-xAlx (OH)2]x+ [CO3]x/n. mH2O and [Ni1-x Mg1-xAlx (OH)2]x+ [CO3]x/n. mH2O were prepared, characterized and tested in the reactions of dry and oxidative reforming of methane. The precursors were modified with the addition of nickel during the precipitation or by impregnation, in order to increase the thermal stability and dispersion of the active metal and the resistance against carbon deposition during the reaction. The catalyst precursors were characterized by X-ray diffraction, thermal and gravimetric analysis, atomic emission spectroscopy, surface area determination (BET method) and temperature programmed reduction. The results indicated that the precipitation method led the formation of the hydrotalcite-type structure and that the variation in the calcination temperature resulted in mixed oxides with the desired structure: at 650 °C the mixed oxides were formed, but when the calcination temperature was increased to 850 °C these oxides had become more stable. It was observed in the catalytic experiments that the addition of different amounts of magnesium influenced the activity and stability of the oxides, when compared with samples that contained only Ni/Al. The mixed oxide with composition 12.67% Ni-Mg1,35/Al was the more active and resistant to deactivation during the reaction.

    A semidecidual forest fragment located in Parque Eco-Esportivo Damha, São Carlos, SP, was studied. The purpose was to sample the diversity of Lepidoptera larvae, their host plants and associated parasitoids. Five different plant species were sampled during 13 months using an entomological umbrella; 266 larvae belonging to 11 families and 26 genera were obtained. The most abundant family was Geometridae, with 32.81% of total amount, followed by Nymphalidae and Gelechiidae. The most abundant genus was Eois (Geometridae) with 28.20% of total larvae amount. The major occurrence of larvae was between the end of raining period and the beginning of the dry period. Using the saturation curve is observed that the survey was not sufficient to sample the real diversity of larvae of this forest fragment. During the work, 10% of larvae were parasitized and a total of 907 parasitoids emerged from different hosts, all koinobionts. Tachinidae was the most frequent parasitoid registered and occurred on Quadrus sp.; The most abundant parasitoid in number of specimens was Copidosoma sp. Polyembrionic parasitoid, attended by 787 found on Plusiinae (Noctuidae).

    In this work a portable fluorimeter was developed and used for determination of chlorophyll a in water samples. The instrument was constructed using the following components: a microcontroller (PIC18F4550), two LEDs as light source, a multichannel photodiode (TCS-230) as detector and a digital display. LEDs with maximum emission at 405 and 760 nm were used. The detector is equipped with three internal optical filters inside with maximum sensitivity at 480, 540 and 690 nm besides the possible use without the optical filter with high sensitivity in the visible spectral region with maximum sensitivity at 680 nm. The microcontroller works as central processing unit controlling all components of the instrument by a program previously recorded in its memory eliminating the need of a microcomputer. The fluorimeter was calibrated using standard solutions of fluorescein and rhodamine 6G in HCl 1.0 x 10-5 mol L-1 and performance was compared with a commercial spectrofluorimeter, and the results are in agreement at a confidence level of 95%. A linear response range for fluorescein was obtained between 0.5 and 100.0 x 10-6 mol L-1 and a correlation coefficient of 0.996 and for rhodamine 6G a linear response range between 0.2 and 10.0 x 10-6 mol L-1 was obtained and a correlation coefficient of 0.989. The fluorimeter was used for determination of chlorophyll a in water samples and blue algae culture medium. The results were compared with a spetrophotometric method and were in agreement at a confidence level of 95%. A linear range of between 2.5 and 1333.6 x 10-6 g L-1 for chlorophyll a was obtained with a correlation coefficient of 0.995. The concentration range attend the requirements of CONAMA resolution n° 357 that classifies the water quality covering the concentrations of 10.0, 30.0 and 60.0 x 10-6 g L-1 for different classes of water. The fluorimeter is inexpensive, easy to use shows, low power consumption allowing the feed with batteries, small size (10 cm x 20 cm x 15 cm) and with weight of 0.76 kg. The fluorimeter can be used to determine species with excitation at 405 and or 476 nm and emission across the visible range with excellent performance.

    The northeast area of São Paulo state was originally covered by cerrado and semideciduous forest, but for the last two centuries, it has experienced distinct cycles of human exploitation of its fertile soils. Despite of intensive human activities, large habitat loss and fragmentation of the native vegetation cover, pumas (Puma concolor) still inhabit remnant habitat fragments in the northeastern area of the state. In this study, by using fecal DNA and molecular markers, we investigated demographic and genetic issues on pumas to aggregate basic information for conservation efforts to maintain long term viable subpopulations of this toppredator in the region. Between 2004-2008, we identified 17 animals (13 females and four males) inhabiting two of the last natural refuges in the area; five females represented resident adults indicating that both refuge areas may act as a source of individuals in the landscape. Only three animals did not exhibit any degree of relatedness, and we found evidence of philopatry, behaviour already described in North American populations. By using mark-recapture-DNA-based methods, we estimated a density of 9.36 ± 2.54 animals/100 km2 inside and surrounding these areas (~260 km2), the largest density estimate for this species reported in the literature. The high abundance may reflect an absence of direct competitors, as well as large prey availability and absence of similar high quality patches in the matrix; mainly females tend to tolerate higher home-range overlap when many resources are available. Considering that pumas may disperse throughout the matrix, we quantified aspects that will probably have influence on the species viability in the area, such as roadkills (11; 10 males and one female) and puma-human conflicts (six events). Especially male pumas tend to disperse long distances from their natal area to occupy new home-ranges, avoiding inbreeding and maintaining high levels of gene flow. Thus, to qualify the dispersers movement success, in a higher geographic scale, we sampled 37 pumas and tested the hypothesis of lack of genetic structure among the natural areas in the region. We observed that pumas in the northeast area of São Paulo state constitute a single population, have high levels of genetic diversity (HE=0.79; mean of 10 alleles per locus) and are related to each other. We also found evidence of a recent bottleneck event in this 10 population. In spite of the huge landscape transformation in consequence of human activities, we concluded that pumas still maintain some levels of gene flow among the protected areas of the study area larger than 2,000 ha and more than 70 km distant one from another, so conservation efforts should be concentrated on the maintenance of this flow. We recommend that puma management should be conducted at the landscape level by increasing habitat connectivity, such as, (1) creating new protected areas; (2) applying an alternate cutting approach in eucalyptus plantations; (3) maintaining habitat patches in private properties; (4) creating structures to allow highway crossing of pumas; (5) designing educational actions to change community perception of large carnivores.

    The effective implementation of appropriate development plans to the reality of the work becomes a crucial issue for a good construction companies performance. The ability to presage potential barriers in implementation enterprise enables companies to work in uncertain environments and solve any problems prior to the execution tasks, thereby protecting the production. The emergence of a new concept for management construction has been widely discussed, the Lean Construction. Given a set of practices linked to concepts and basic principles of Lean Construction and considered essential for effective planning, evaluation was made in 33 plans prepared by a consulting planning firm. Thus it was possible to achieve the main goal of this research: assessing the impact of good practices of PCP in the planning construction effectiveness. Other objectives were: evaluate the impact of effective planning and control in enterprise performance, analyze the causes for the non-completion of work packages, verify variations in indicators of production performance according to the type of company, and check for correlation between indicators studied. The results hasn t shown a direct relationship between the indicators. It was observed that 65% of good planning practices were used by the consulting planning firm and that it, along with its contractors, may improve the effectiveness of the planning process. It was possible to determine a valid model for predicting the time deviousness.

    Because the close relationship between men and dogs, possibly some ectoparasites of dogs can be observed parasitizing man. The tick Rhipicecephalus sanguineus is an ectoparasite that has the ability to carry and transmit pathogens to humans. This arthropod, that is blood-feeding, is the main biological vector of the bacteria Ehrlichia canis. Currently, the diagnosis of this disease ehrlichiasis is based on blood, biochemical and serological tests, although they are unreliable for diagnosing the disease, since their clinical and clinicopathological features are largely nonspecific. Tetracyclines are commonly used in the treatment of ehrlichiosis, but studies show that some dogs remain positive for E. canis after treatment or after the loss of spontaneous infection. The chronic ehrlichiosis, having high prognosis fails, can result in high mortality. Therefore, more sensitive and reliable tests may help in the selection of dog carrying the disease. The PCR (polymerase chain reaction) has been used successfully in the diagnosis of E. canis. However, this molecular technology requires expensive equipment and specialized personnel to handle, which limits its use in laboratories routines. A more sensitive, specific, and simple to detect the microorganism method is desirable. In this work we develop the technique for detection of the bacterium Ehrlichia canis using the LAMP (Loop- Mediated Isothermal Amplification), which proved being very effective. Specific sequences of the E. canis dsb gene (disulfide bond) were used as target for the tested techniques. Dsb gene was highly specific in order to detect E. canis, since it is divergent of phylogenetically similar bacteria. Performed molecular tests showed a disease incidence greater than that indicated by authors using traditional diagnostic techniques. In the public kennel, 80% of the samples were infected, while in private clinics and veterinary hospital 40% had the disease. The developed diagnostic technique using LAMP is more sensitive than PCR, highly specific and does not require the prior DNA extraction to amplification. In addition, the product of amplification can be seen with the naked eye. We conclude that the diagnosis by the LAMP method enables the specific and high sensitivity identification of infected animals with minimal laboratory settings. These factors make possible the use of this diagnostic methodology for veterinary clinics, laboratories and educational institutions.
