(Universidade Federal de São Carlos, 2019-03-15) Langendonck, Melanie Fairlie Pearson Van; Elias, Nassim Chamel; https://lattes.cnpq.br/4216525883778695; https://lattes.cnpq.br/6743223726658670
Children with Autism Spectrum Disorder (ASD) may present deficits in communication and social interaction, as well as restricted and repetitive behaviors and interests. Research has been carried out in the area of music, however the majority of studies for this population contemplate the use of music as a therapeutic and not an educational activity. Were found studies that evaluated the teaching of rudimentary reading of musical notes through stimulus equivalence and mostly with individuals with typical development. This study had as a general objective to verify the effects of conditional discriminations between figures (each composed of a background color and a specific musical symbol) and keys in the recognition of musical notes to the piano in a boy with 4 years and 10 months of age diagnosed with ASD. As specific objectives, verify if the control of the answer would be given by the color or symbol of the musical figures, examine the formation of classes of equivalent stimuli and test the recombination of the notes learned in new musical sequences. The method had an experimental design with multiple baseline between sets of musical notes. The teaching, which had procedures of the Applied Behavior Analysis (ABA), was divided in three phases, in which seven musical notes written in the treble clef, from central C to central B, were taught in configurations that ranged from one to 38 combined and recombined symbols (units). A pre and post-test were applied at all phases. The connection between symbol and color cards and the corresponding keys (AB) and between cards with symbol and color and the name of the corresponding note (AD) were taught. The procedure of teaching discrimination of musical notes promoted the acquisition of repertoire referring to musical reading, as measured by the response of playing the corresponding key. The results suggest efficacy in teaching with an achievement of over 70% in the teaching and testing phases. Emerging relations between teaching classes could also be noticed. It is intended with this research, expand previous studies found In music and equivalence with adults for a child with ASD.
Transporte eletrônico em nanofios de SnO2 dopado com Sb: transição metal-isolante induzida pela dopagem e fotocondutividade persistente
(Universidade Federal de São Carlos, 2019-03-15) Costa, Ivani Meneses; Chiquito, Adenilson José; https://lattes.cnpq.br/7087360072774314; https://lattes.cnpq.br/0666347734352570
In this work we studied the structural, optical and electronic transport properties of intrinsic and doped SnO2 nanowires with different concentrations of antimony (Sb) grown by the Vapor-Liquid-Solid mechanism (VLS). Results from X-ray diffraction (XRD) combined with Rietveld refinement, indicated the formation of single phase samples corresponding to the tetragonal Rutile structure of SnO2 belonging to the P42/mnm spatial group. Raman spectroscopy data also indicated the formation of rutile phase corroborating the XRD measurements. The appearance of inactive vibrational modes (242 and 284 cm-1) only for the doped samples was attributed to the effects of disorder. XPS analyzes confirmed the presence of Sb in doped samples. The presence of Sb was evidenced by the superposition of the O1s and Sb3d regions and only one oxidation state (Sb5+) was detected. Absorbance spectra indicated that the doped samples exhibited an energy gap (3,40 - 3,66 eV) greater than that for pure samples (3,3 eV). This result is consistent with the Burstein-Moss model which describes the shift of the absorption limit due to the increase of the density of charged carriers. From photoluminescence spectra it was observed that the SnO2 samples presented three emission peaks related to oxygen vacancies, V0+ (red), (V0+)iso (yellow/orange) and V0++ (green). The green emitter center was actived only below T = 100 K. ATO samples showed only two emission peaks: the red emitting center (V0+) also present in pure samples and a doping-related blue-violet emitter center located at 2,58 - 2,84 eV. Temperature dependent resistivity data showed that the SnO2 samples presented a typical behavior of a semiconductor material, while ATO samples presented a transition from an insulating state (dR/dT < 0) to a metallic one (dR/dT > 0) around 90 - 170 K depending on the doping level. The semiconductor phase was characterized by two electron conduction mechanisms: thermal activation and variable range hopping (VRH). The metal phase was characterized by electron-electron and electron-phonon scatterings. The electron-phonon process was predominant at high temperatures leading to the calculation of the Debye temperature of the samples (ΘD = 602 - 657 K). All doped samples were characterized by doping levels above the Mott limit (ncMott = 6,7 x 10^23 m-3) thus satisfying the Mott criterion for observation of the metal-insulator transition based on the electron-electron interaction. In addition, it was observed that both the nanowire device and the SnO2 nanowire network device exhibit persistent photoconductivity (PPC) which is directly related to the presence of oxygen vacancies. For the nanowire network, the PPC effect was only observed under vacuum conditions, since under room environment conditions the nanowire-nanowire junctions strongly affect the electric current through the device. However, only for the single nanowire device we observed PPC also under high temperatures. The energy level attributed to the emitting center V0++ can be seen as responsible for the anomalous behavior in the low temperature resistivity curves (T < 100 K).
Análise das relações entre propriedades físicas e mecânicas em diferentes regiões de extração da madeira de Cambará (Erisma Uncinatum Warm)
(Universidade Federal de São Carlos, 2019-03-15) Aquino, Vinicius Borges de Moura; Christoforo, André Luis; https://lattes.cnpq.br/7623383075429186; https://lattes.cnpq.br/5303314880493623
This research had the purpose of evaluating the relationship between the physical and mechanical properties of Cambará wood extracted from three distinct sites: Vera, Mucajaí and south of Rondônia. The possibility of estimating (linear regression, exponential, geometric and logarithmic models) the physical and mechanical properties as a function of apparent density will also be evaluated. This research was motivated by the fact that there is no consideration in the normative code the influence of the extraction regions on the physical and mechanical properties of timber, since different climatic conditions, vegetation and soil in which the tree can influence their growth and, consequently, the values of its physical and mechanical properties. The ABNT NBR 7190, the Kruskal-Wallis variance analysis and the resampling technique were considered in the accomplishment of the procedures. The results of ANOVA indicated an equivalence index equal to 100% for the properties of the Vera region, 94% for the regions of Mucajaí and South of Rondônia. The resampling technique led to similar results for the Vera and Mucajaí regions and for the southern region of Rondônia, the equivalence index was equal to 89%. The results of the ANOVA to estimate the physical and mechanical properties in function of the apparent density indicated that it was not possible to make such estimates for Cambará wood.
Educação ambiental no facebook: a propagabilidade dos memes sobre conservação da biodiversidade na página zoololgico
(Universidade Federal de São Carlos, 2019-03-15) Emídio, Leticia Stefania; Silva, Rosana Louro Ferreira; https://lattes.cnpq.br/2635824351245453; https://lattes.cnpq.br/4188879880000074
The participatory culture and the collaborative content creation in social networks have turned memes into elements of communicative expression that are widespread today. This popular phenomenon that transits between the online and offline world has raised interest in testing the potential for science divulgation of this tool in consonance with the principles of Critical Environmental Education, which aimed the democratization in constructing and accessing to knowledge in the area of biodiversity conservation and the work of zoological institutions of the world. In this research, we tested the use of memes as a communication strategy for spreading socio-environmental content in Facebook, in a humorous but also dialogic and critical approach. Creating a Facebook page called ZOOLOLGICO, we sought to quantitatively and qualitatively characterize the public's acceptance of the proposal, using the insights of the page and an online questionnaire. The form was answered by 45 people (about 5% of the followers) at the end of 4 months of collection, to understand the nature of the relationships and interactions that have been formed between the followers of the page and the published content. The results show us that the the public accepted well the proposal, reaching almost 900 followers in just 123 days, and with publications reaching more than 50 thousand views. The public that answered the questionnaire was equilibratedly divided between the general public and people directly involved in the work of zoos, but the overwhelming majority were graduates or postgraduates (91.1%) in the area of Biological Sciences and Health (66.7%). The feedback received by the questionnaire was also very positive, with the overall content being classified as excellent (57.8%) or very good (35.6%), with a high consumption content of the content posted, and with several requests for the page to continue to function after data collection. The questionnaire also allowed us to raise some reasons that discourage the visit to zoos, specific notes about some of the posts and about four indicatives of conceptions’ changes about the importance of zoos’ conservation work and maintenance of the animals’ welfare in captivity.
Análise da expressão de orexina-A e B em neurônios ativados por CO2 no hipotálamo de ratos nas fases clara e escura do ciclo circadiano
(Universidade Federal de São Carlos, 2019-03-15) Silva, Eliandra Nunes da; Horta Júnior, José de Anchieta de Castro e; https://lattes.cnpq.br/2577584360099382; Dias, Mirela Barros; https://lattes.cnpq.br/3203493045928389; https://lattes.cnpq.br/0614927294579784
Orexinergic neurons (OX) located in the lateral hypothalamus (LH), lateral and medial perifornical area (LPeF/MPeF) and dorsomedial hypothalamus, through orexin-A or orexin-B, can exert influence on hypercapnic ventilatory responses, acting directly in respiratory control areas or modulating the activity of other chemossensitive sites. Despite the evidence about the role of orexinergic system in central chemoreflex, the differences in the activation of these neurons by CO2 in the light and dark phase of the circadian cycle, as well as the likely differential activation between the hypothalamic nuclei that contain these neurons, is poorly understood. In the present study, in Wistar rats submitted to normocapnic or hypercapnic conditions (7% CO2), immunohistochemical protocols evaluated the number of Fos, orexin-A, orexin-B and neurons that co-localize Fos with Orexin-A or B in the LH, LPeF, MPeF e DMH in the light and dark phase of the diurnal cycle. Quantitative analysis of the expression of immunoreactive neurons showed that hypercapnia causes an increase in the number of neurons expressing Fos protein in LH, LPeF, MPeF and DMH in the light and in the dark phase of the diurnal cycle. In addition, there was an increase of orexin-A in hypercapnia in the light phase in LH, while there was decrease of orexin-A in hypercapnia in the dark phase in LPeF, MPeF and DMH. Neurons that co-localize Fos and orexins augmented in both phases of the diurnal cycle in the LH, LPeF and DMH, whereas in the MPeF this increase was observed only in the light phase. These results attest to the chemosensitive function of the hypothalamic region comprising LH, LPeF, MPeF and DMH and suggest that the role of these areas in the central chemoreflex involves the orexinergic neurons, independently of the phase of the light-dark cycle, with the exception of the MPeF, that seems to have a subpopulation of orexinergic neurons that act especially in the light phase.
A influência da hipóxia severa na sensibilidade barorreflexa de tilápia-do-Nilo (Oreochromis niloticus)
(Universidade Federal de São Carlos, 2019-03-15) Troiano, Natalia Miriã; Florindo, Luiz Henrique; https://lattes.cnpq.br/2797832406818407; https://lattes.cnpq.br/4601493375036247
The importance of the circulatory system in homeostasis of different animals is unquestionable. Given that one of the basic factors that determine blood flow is blood pressure, the short- and long-term regulation of this variable is essential for the various functions of the circulation to be performed adequately. The baroreceptor reflex is one of the most known mechanisms of rapid control of blood pressure, causing any change in this variable to result in an inversely proportional change in heart rate and in systemic vascular resistance, aiming at pressure normalization. However, another factor that can cause reflex changes in heart rate is the oxygen environmental concentration, with hypoxia being relatively common in several aquatic environments. The basic response to hypoxia in teleosts is the reduction of heart rate by chemoreflex; being attributed to this bradycardia possible physiological roles, such as improving oxygen uptake and protection of the myocardium. Thus, with the knowledge that both baro and chemoreflex are physiologically important for the animal and, in certain situations, may trigger antagonistic responses in heart rate, the present study aimed to investigate whether the condition of severe hypoxia has an influence on baroreflex sensitivity of Nile tilapia (Oreochromis niloticus). Therefore, administrations of phenylephrine and sodium nitroprusside were carried out in animals in the condition of normoxia and severe hypoxia; being heart rate and mean arterial pressure in the ventral aorta continuously recorded. Then, the baroreflex function of all animals was investigated by analysis of the sigmoid curve of the barostatic reflex and the baroreflex gain was calculated by equations proposed in literature. The present study was the first to analyze the barostatic reflex by means of the sigmoidal curve in fish and revealed that severe hypoxia increases the baroreflex sensitivity of Nile Tilapia (Oreochromis niloticus), which occurs due to an increase in the animal's regulatory capacity against hypotension.
A organização como um campo: o caso de uma fundação de apoio de uma instituição federal de educação profissional, científica e tecnológica
(Universidade Federal de São Carlos, 2019-03-15) Lima, Luiz Otavio Gonçalves de; Candido, Silvio Eduardo Alvarez; https://lattes.cnpq.br/0194644249955417; https://lattes.cnpq.br/4989335651462645
The emergence of the "third sector" in Brazil can be explained by the analysis of attempts to implement the economic development projects that occurred during the 20th century in the world, and especially in the Brazilian State. Among the organizations that integrate it are the foundations of support that currently constitute a reality of the operationalization of teaching, research and extension of the Federal Institutions of Professional, Scientific and Technological Education. However, the performance of these entities has received numerous criticisms, either by society or by the control bodies. Considering these questions at the national level and aware that the organizational study is permeated by theoretical approaches that fail to reveal the true dynamics of organizations, this research proposed the use of an alternative metaphor to the orthodox conceptualizations available for the understanding of institutions, suggesting that organization can be understood as a strategic field of action. Thus the present investigation had as objective to analyze the historical construction of the cultural- political dynamics of FADEMA, foundation of support of IFSULDEMINAS. In order to do so, a qualitative and longitudinal and retrospective research was performed, since the study does not refer to a certain moment, on the contrary, the research sought to explore facts that have occurred in the trajectory of FADEMA since its genesis until the year 2018. The research method used was the case study. As for data collection, this involved the bibliographical, documentary and semistructured interviews, which were analyzed and interpreted by the content analysis technique. In this way, it was observed that the metaphor used for this investigation allowed the understanding of the social construction of the FADEMA environment, as well as of its power relations, both determined by the internal and external dynamics of the field.
Forma urbana, densidade da população e zonas climáticas locais: influências e avaliação da ilha de calor urbana em Bogotá, Colômbia
(Universidade Federal de São Carlos, 2019-03-15) Aguilar, Edwin Alejandro Ramírez; Souza, Lea Cristina Lucas de; https://lattes.cnpq.br/0083847008256434; https://lattes.cnpq.br/7318390545047284
The study of the Urban Heat Island (UHI), as the main phenomenon of climatic alteration caused by urbanization, is fundamental to understand the effect of urban areas on their regional climate. This dissertation presents a study based, first, on understanding the influence of the urban form, created by the size (population) and concentration of its population (population density) in UHI of the city of Bogotá, Colombia. Second, the thermal changes that occur within the urban area are explored through the classification of the Local Climate Zones (LCZ), based on the urban form parameters. The first part is characterized by the urban, sub-urban and rural thermal contrasts according to the annual temperature differences (ΔTu-r). For this, air temperature data (obtained from eleven meteorological stations) were sampled and statistically treated to associate Population (p) and Population Density (PD) data for each station. Different variables of the urban land cover and the urban morphology were extracted and analyzed for each sector around the stations. Among the data, a significant positive relationship was found between PD and ΔTu-r. In the same way, the parameters of the urban form most correlated with PD and ΔTu-r, were the Sky View Factor (SVF) and the Permeable Surface Fraction (%PSF). A prediction model based on PD was proposed and applied in the creation of a city thermal map. The second part is characterized by the stations and their areas of influence LCZ classification. Daily observations of the maximum (Tmax), minimum (Tmin) and mean (Tmean) and hourly (T7:00, T13:00 and T19:00) air temperature were obtained. Their distribution and variation were analyzed, as well as the air temperature-based indices and thermal sensation indices that were calculated to identify patterns in the behavior and thermal differences (ΔTZCLX-ZCLD) between the stations and their ZCL. The results showed that densities higher than 14500 inhabitants/km2 can cause ΔTu-r >1°C, greater sky obstruction (SVF < 0.45) and a great green areas and vegetation cover decrease (%PSF < 30%). On the other hand, observations, air temperature-based indices and thermal sensation indices, created by Tmin, T7:00 and T19:00 data, clearly show the variations and differences between the stations and their LCZ. Values of ΔTZCLX-ZCLD > 5°C were found in the densely urbanized LCZ. This dissertation concludes that the urban form, caused by the population density, has a great effect on temperature differences, these thermal changes are most clear between open and compact LCZ areas within the city of Bogotá.
Um teorema fundamental para hipersuperfícies em produtos torcidos semi-riemannianos
(Universidade Federal de São Carlos, 2019-03-15) Melara Estrada, Mynor Ademar; Villagra, Guillermo Antonio Lobos; https://lattes.cnpq.br/6962956853017869; https://lattes.cnpq.br/3320692889941905
The aim of this dissertation is to show a demonstration of a fundamental theorem for existence of isometric immersions for hypersurfaces in a warped product space where the base is a interval and the fiber is a spatial form, both with semi-Riemannian metrics, and in addition to that, present an application of this theorem for horizons in a Robertson-Walker spacetime of dimension 4, both based on the work of Marie Am´elie Lawn and Miguel Ortega in [J. Geom. Phys. 90 (2015) 55-70]. Such a result, generalizes fundamental theorems for hypersurfaces obtained, by B. Daniel for Riemannian products in [Trans. Amer. Math. Soc. 361 (2009) 6255-6282], by Q. Chen and C.R. Xiang for Riemannian warped products in the case of fibers with zero sectional curvature in [Acta Math. Sinica. 26 (2010) 2269-2282]; and by J. Roht, in the case of Lorentzian products with Riemannian fibers in [Int. J. Geom. Methods Mod. Phys. 8 (2011) 1269-1290]. Also, based on the demonstration of local uniqueness of B. Daniel’s fundamental theorem, we prove that the isometric immersion obtained in Lawn and Ortega’s theorem, is unique up to a global isometry.
Análise do modelo input-output-outcome do processo de inovação de produto e processo na indústria brasileira de transformação
(Universidade Federal de São Carlos, 2019-03-15) Ishizaka, Artur Yuiti; Lizarelli, Fabiane Letícia; https://lattes.cnpq.br/4525431419326559; Toledo, José Carlos de; https://lattes.cnpq.br/9421627326330417; https://lattes.cnpq.br/8661401057152208
This dissertation sought to analyze the relationship between the inputs and outputs of the product and process innovation process, and its impacts on the performance of firms, through the application of a Partial Least Squares Structural Equation Modeling (PLS-SEM), using data from the Innovation Survey 2014 (PINTEC). The main variables of inputs, outputs and outcomes of innovation were identified in the literature through a systematic literature review, and a research model was proposed. Constructs of internal (internal-to-company resources) and external inputs (acquisitions), product and process outputs, and outcomes related to products, market share, and business processes were used. The application of PLS-SEM allowed the evaluation of the composition of each construct, relationships between them and impacts of control variables of firm size and technological intensity of the companies in the proposed model. All relationships between constructs were confirmed as positive, except for the relationships between external inputs and product outputs and between product outputs and outcomes related to productive processes, which presented negative relationships. Also, a distancing between the processes of product and process innovation was noticed, evidencing the lack of integration between them. The impact of the size and technological intensity of the companies were significant for some of the model relationships. The control variable of firm size evidenced mainly the greater capacity of larger companies in dealing with the parallel development of innovations of product and process. As for the technological intensity variable, it showed that companies of low technological intensity tend to benefit more from product and process innovations in terms of product and market share outcomes.
Avaliação de bacias de detenção de águas pluviais implantadas no município de São Carlos, SP
(Universidade Federal de São Carlos, 2019-03-15) Rodríguez, Carlos Andrés Martínez; Teixeira, Bernardo Arantes do Nascimento; https://lattes.cnpq.br/1166854416745527; https://lattes.cnpq.br/2894639931561257
In Brazil, the last decades registered an accelerated growth of urbanization, increasing the waterproofing of the soil and the direct flow, generating floods in the urban areas. As a measure to mitigate the resulting impacts, since the 90’s decade, the concept of compensatory techniques has been adopted, among them, the Detention Basins (DB), which are centralized techniques that are characterized by being dimensioned for large return periods, with the objective of detain rainwater over a period of time, reducing the flood peak. Due to the obligatoriness by the municipal legislation, DB are being implanted in new urban developments in the municipality of São Carlos, to guarantee the conservation of the pre-urbanization flow. According to this panorama, the present research has as objective the evaluation of these units under physical aspects, of project and urban integration. Were identified and characterized 23 Detention Basins and 3 Detention Basins Systems by satellite images and on-site visits, and were evaluated through variables consulted in the bibliographic review and adapted to the municipal reality. Also, aspects as sizing, construction, maintenance, costs and integration of some of the DB were analyzed through consultation of the memorials in the drainage projects and interviews with the agents involved with the issue. These resources permitted to identify that the location of the DB was directed to the perimeter zones of the municipality. Most of them being close to residences, but without being integrated in the same space of coexistence with the community, being isolated through gates and wiring. All DB have the sole function of hydrological control. The exception were three Basins that did not have a bottom hole for water outlet. The others DB presented shallow water sheet formation by the precipitation event and emptying it within 24 hours after rainfall. Regarding the state of conservation, it was observed as a common factor the presence of excessive vegetation and solid residues due to the lack of frequent maintenance activities. About sizing, was verified the use of the rational method to calculate the maximum flows. However, differences were identified in the calculation of hydrological parameters and the volume of detention in Basin’s drainage project, compared to the equations established by the Municipal Direction for Drainage Projects. Most DB had energy dissipators in their inlet structures preventing erosion, as well as elements for sediment retention. The activities necessary for the construction and operation of the DB do not represent a high complexity, being these mainly the soil movement and to prune along with the solid waste removal respectively. Two DB implantation cost ranges were identified, one of them at around R$25/ m³ and the other of R$50/m³; the calculated cost for the maintenance of the DB was R$342/ha.year. The DB implanted comply with the hydrological control function, but for a better integration of the technique in the urban environment it is necessary an improvement in the maintenance activities as well as the consideration of the multifunction of them in the conception of the urban project.
Tração mobilizada de reforços geossintéticos sob condições operacionais e efeito de umedecimento
(Universidade Federal de São Carlos, 2019-03-15) Santos, Matheus Cardoso dos; Portelinha, Fernando Henrique Martins; https://lattes.cnpq.br/0791082339645058; https://lattes.cnpq.br/1812526828544037
The use of low permeability fine local soils instead of granular materials has been common in several countries due to the significant reduction of the costs associated with the transport of granular materials extracted from deposits. In fact, the use of fine soils may result in adequate behavior of reinforced soil structures under unsaturated conditions. However, in rainy periods, the strength and stifness of the structure can be affected and cause excessive deformation or even rupture. Although there are some observations on the effect of wetting on fine and geosynthetic soil behavior, few studies have quantified the effects of infiltration on mobilized tensile load and deformation. Thus, the present work aims to evaluate the effect of infiltration on the mobilized tensile load and deformations in layers reinforced with geosynthetics. For this purpose, an equipment called Load-transfer Soil to Geosynthetic System (LSGS) was developed, designed to simulate the actual mechanisms of action of a reinforced layer. The equipment simulates the mechanical response of the geosynthetic reinforcement under operational conditions in a reinforced layer with direct measurement of tensile-strain behavior under simultaneous conditions of overload and wetting. For the monitoring of the wetting front, the tests were instrumented with moisture sensors and tensiometers. In the tests, two different types of soil (well-graded sand and plastic sandy clay) and three geosynthetics (geogrid, woven geotextile and non-woven geotextile) were used. The results showed that the equipment simulated satisfactorily a layer reinforced with geosynthetics and allows to measure the tensile load behavior under operational conditions of reinforced soil walls with geosynthetics. The confinement increased the stiffness of the nonwoven geotextile three times but did not provide changes in the geogrid and the woven geotextile in both soils. The infiltration caused an increase in the deformations and the mobilized tensile load of the geogrid and woven geotextile and affected the resistance at the non-woven clay-geotextile soil interface significantly, so that the deformations resulting from the infiltration process were exponential.
Intervenção para crianças, adolescentes e suas cuidadoras expostas à VPI
(Universidade Federal de São Carlos, 2019-03-15) Otaguiri, Alliny Tiemi Moia; D'Affonseca, Sabrina Mazo; https://lattes.cnpq.br/0381029115416584; https://lattes.cnpq.br/6187635324223493
Intimate partner violence (IPV) consists in a public health matter, which affects not only its direct victims, but also thousands of children who live in homes where the phenomenon occurs. It is known that the exposure of children and adolescents to IVP may lead to short-, medium-, and long-term impacts throughout their development. Thus, intervention programs aimed at this population are necessary, both from the attenuation of IPV exposure consequences, as well as from the prevention of the perpetuation of the cycle of violence point of view. Also, it should be noted that both the quality of the relationship between the mother or caretaker and the child, as well as the mental health situation of the mother/caregiver carry deep influence along the development of children. Considering such context, the present dissertation was developed, and composed of three scientific articles related to the theme. The first article consisted of a literature review which aimed to identify interventions conducted with parallel groups of mothers and their children who have been exposed to IPV. The analyses of the 13 selected articles has allowed us to conclude that intervention programs which treat both mothers and children lead to positive results for both parts. Also, improvements on mothers’ symptoms were related to improvements on their children’s. In this way, intervention programs that aim at the prevention and treatment of the effects of IPV exposure, both for mothers/caregivers and for their children, present as important resources. The second article describes the process of adapting the Community Treatment Program of Witness Groups of Women Abuse (CGTP), a Canadian intervention program for children, adolescents and their mothers/caregivers exposed to IPV, to the Brazilian reality. Our research began once the authorization to conduct the adaptation process was granted by the owners of the original program. The translated version of the program was submitted to the evaluation of expert judges, who provided their assessments of the content and relevance of the activities to the Brazilian reality, in terms of cultural, semantic and conceptual adequacy. The judges found the structure, approach and activities of the program to be relevant to the Brazilian context. The modification of some games and activities included in the sessions was suggested, as well as the refinement of some language aspects, such as the use of a more informal language on the materials intended for participants. Finally, on the third study, professionals with experience on working with the targeted population (children, adolescents and their mothers/caregivers exposed to IPV) were interviewed. This study was developed in addition to the cross-cultural adaptation procedure, and the participants were consulted about what they considered relevant for the development of an intervention such as the CGTP. The professionals pointed out characteristics such as: conducting sessions in groups divided by age, with occasional meetings between families and children and ludic activities. They recommended the approach of themes such as self-protection, assertive communication skills, feelings of guilt and shame, prevention of violence, rules, limits, notions of bodily autonomy and consent, emotional education, self-esteem, among others. By the end of the adaptation process, it was possible to conclude that the adapted intervention program (“Vida livre de violência para mães e filhos”) was adequate to Brazilian reality.
Análise dos efeitos do tratamento preemptivo com terapia por fotobiomodulação a laser (660 nm) na viabilidade de retalho cutâneo em ratos
(Universidade Federal de São Carlos, 2019-03-15) Martignago, Cintia Cristina Santi; Bossini, Paulo Sérgio; https://lattes.cnpq.br/1256982144741336; Parizotto, Nivaldo Antonio; https://lattes.cnpq.br/5527703735628408; https://lattes.cnpq.br/9654644689893928
Skin flap (SF) is a technique used in plastic surgery for many years to repair large lesions of the skin either due to trauma or after operative procedures, however, it presents as a complication tissue necrosis. A treatment that presentes scientific evidence for the reduction of SF necrosis is photobiomodulation therapy (TFBM). Due to the number of parameters involved in the dosimetry of this therapy, some gaps still exist in the literature. Thus the objectives of this work were; find the best site of application with the same irradiation time and investigate the effects of preemptive treatment associated with postoperative treatment with TFBM at different doses on viability in SF in rats. For this, 81 rats (Rattus norvegicus), males divided in two studies were used. In the first study, 18 animals were randomized into three groups. Group I (GI) simulation of TFBM, group II (GII) TFBM in three points in the cranial base of the SF and group III (GIII) TFBM in twelve points inside the SF. The animals of the GII presented smaller area of the necrosis and greater quantification of the collagen when compared with the control group. It was concluded that the application of the TFBM in three points in the cranial base of the SF was the most efficient. In the second study, 63 rats were randomized into five groups: Control Group (CG): TFBM simulation; Preemptive group + laser 1,1J (GP1): preemptive TFBM with 1.1J of energy per point; Preemptive group + laser 4J (GP4): preemptive TFBM with 4J of energy per point; Group 1 (G1): TFBM immediately after surgery with 1, 1J of energy per stitch, Group 4 (G4): TFBM immediately after surgery with 4J of energy per point, and on the third day after randomization the animals underwent cranial base SF surgery. The animals of GC, GP1 and GP4 had their treatments started 72 hours prior to surgery and were subdivided into 2 experimental periods, the first being on the day of SF. In the first evaluation it was possible to find a higher number of vessels, mast cells and greater expression of FGF and VEGF in GP1 compared to CG and higher expression of these same factors in GP4 compared to GC. In the second evaluation GP1 showed better results when compared to GC in the majority of analyzes. Thus, this study demonstrates that preemptive treatment with TFBM with the application of 1.1J of energy per point was effective in improving SF.

There is enough evidence that copper plays a crucial role in regulating phytoplankton metabolism. However, despite its requirement in trace amounts, there is a literature gap on the physiology of microalgae exposed to environmentally relevant copper concentrations; most literature report results using ~10 to 100 times higher copper than what can be detected in most natural ecosystems. This study aimed at investigating some physiological responses of Kirchneriella obesa exposed to copper, including environmental relevant concentrations in an ample range (3x10-9 to 4x10-5 mol L-1 free Cu2+ ions)(chapter 1) and the effects of three different copper concentrations on the co-cultivation of K. obesa and Chlorella sorokiniana (chapter 2). K. obesa’s EC50 was 1,25x10-7 mol L-1 Cu2+. Physiological analyses were performed at 72 h (exponentially growing cells) for both experiments and cultures were kept under controlled conditions. They were monitored daily for cell density, chlorophyll a and maximum photosynthetic quantum yield; biovolume and effective photosynthetic quantum yield, fluorescence quenchings (photochemical and non-photochemical) and rapid light saturation curves were also determined. In addition to these parmeters, for chapter 1, the intracellular and mucilaginous capsule copper content and total carbohydrates and proteins were determined; whereas at the end of the co-cultivation, all previously listed photosynthetic parameters were measured for each species. Intracellular and mucilaginous copper showed that the physiological mechanisms that regulate copper uptake were disrupted at 2x10-7 mol L-1 free Cu2+ ions, when intracellular copper increased linearly with copper increase in the mucilage capsule. The results showed an increase in biovolume with the increment of copper on both unialgal and co-cultures. Effective quantum yield was kept constant up to 10-7 mol L-1 Cu2+ ions but decreased thereafter. The non-photochemical quenching (NPQ) behaved the opposite way as the effective quantum yield, confirming copper induced stress in cells exposed to concentrations higher than 4x10-7 mol L-1 Cu2+ ions. Proteins and carbohydrates presented similar behaviour, increasing noticeably above 10-7 mol L-1, with higher intensity for carbohydrates. C. sorokiniana and K. obesa presented higher growth rates in the co-cultivation than in unialgal cultures when exposed to 2x10-7 mol L-1 Cu2+. This research demonstrated that environmental copper concentrations detected nowadays might affect the physiology of K. obesa and that an effect on copper toxicity may occur during the joint growth of K. obesa with C. sorokiniana. Our results are a contribution towards the understanding of the equilibrium of natural aquatic ecosystems.
Identificação dos fatores críticos ao adequado funcionamento das secretarias administrativas de programas de pós-graduação em uma IFES
(Universidade Federal de São Carlos, 2019-03-15) Kawamura, Luciana Missae; Côrtes, Mauro Rocha; https://lattes.cnpq.br/8988613760967305; https://lattes.cnpq.br/4535473945830886
Some factors are fundamental for the success of an organization and knowing these factors can help the management in the elaboration of a strategic planning in search of better results. The stricto sensu graduate programs are constantly evaluated and their results will determine their success and their permanence in the National Graduate System. The evaluation is carried out every four years based on annual reports that the programs send to CAPES. Completion of the PPG report is carried out through a platform where qualitative and quantitative data are informed regarding the program proposal, teachers, students, intellectual production and social insertion. The responsibility for the data informed is of the Coordination of the PPG, however, the collection, systematization and insertion of data in the platform are done in most cases with the support of the secretariat. Faced with this, knowing the critical success factors of post-graduate departments becomes relevant to assist in the preparation of an adequate annual report. The objective of the research was to identify the critical factors related to the individual and collective competences of the occupants of the function of post-graduate secretaries linked to a Science Center, a federal public university, that contribute to the program. For this, the critical success factors of the graduate programs were raised through the reading of the area documents and the evaluation reports of the programs, and it was sought to know the vision of the current occupants of the secretaries function from interview semi-structured on the functioning of the secretariat, knowledge, skills and attitudes existing and to be developed, strategic planning, evaluation and key critical factors to serve as secretary of PPG. The approach used was people management by competencies. Based on the results obtained, a set of actions was elaborated aiming at improvements in the processes of the secretariats and in the completion of the annual report and consequently search for better results for the program. The results have identified that the servers are committed to the function, have the necessary skills and abilities and that the greatest difficulty is in the volume of activities and in dealing with people. The secretariat is usually the place where the demands and complaints are concentrated, so the secretaries should be proactive, ethical, and have a good relationship with teachers, students and general public. Among the suggested actions are: promotion of face-to-face events or meetings with the participation of the post-graduate secretaries that allow the exchange of information and experiences; sharing of information and clarification of doubts whenever there is a change in procedures; offerings of training or discussion meetings that provide the improvement of the knowledge and skills of the secretaries and search for improvement of the processes that involve the secretary; sharing of the strategic plan of the program with the secretariats; hours, during periods of important demands, so that the secretariat can prioritize these activities.
Partículas rugosas de sílica híbrida aplicadas na transesterificação catalítica

Heterogeneous catalysts are potentially responsible for reducing the cost of producing biodiesel, due to its reusability or use in continuous process. As-synthesized hybrid silicas, containing siloxy sites, can be used as catalysts for the transesterification and are interesting materials due to the facile control of their chemical and morphological properties. In this work, the effect of CTABr surfactant content and cosolvent alcohol chain length on the structural and catalytic properties of hybrid silicas containing occluded CTA+ cations was evaluated. All the prepared materials were actives in the model transesterification reaction. The surfactant concentration in the synthesis had a positive effect on the reaction activity, increasing the TOF¬0 by 2.5 times when the CTABr/TEOS molar ratio was increased from 0.1 to 0.8. This improvement in the catalytic activity can be attributed especially to the reduction of particle size and also to the formation of surface roughness in the silica particles. Likewise, when alcohols with a higher carbon chain was used, higher values of TOF0 were achieved, increasing by 1.8 times higher for the catalyst prepared with 1-butanol in comparison with the one prepared with ethanol. In addition, both variables had a positive effect on catalytic stability, showing that the use of higher surfactant concentration and alcohols with longer carbonic chains are efficient for improving the catalytic properties of hybrid silica particles.
Contribuições ao estudo da secagem da borra de café em leito vibrofuidizado

Brazil is the largest producer of coffee in the world, half of this production is destined to the soluble coffee industry, that generates a amount of waste. The spent coffee grounds leave the fabrication processo f the soluble coffee with 70% (w.b.) moisture content, the reduction of moisture present is essential to reduce storage and transport costs, as well as increase the heating value for direct burning. This work presents characterized the dry and wet spent coffee grounds, through particle size analysis, aparent and bulk density, Hausner index and bed porosity. The analysis of the fluid dynamics of coffee grounds as a function of moisture contente was done, with the purpose of delineating the behavior of the fluidized bed material, identifying the change in fluidization behavior between 40 and 60% moisture contente (w.b.). It analyzed the dry bed elutriation by classifying the particles depending on the speed of the air. Subsequently a mechanical dewatering study was carried out, obtaining a moisture reduction of 0.70 to 0.45 (w.b.) of the spent coffee grounds, obtaining that the pressure applied and the pressing time exerts a statistically significant influence in this step. Finally, the study of thermal drying with experimental design 2² and replica at the central point in a vibrated fluid bed dryer using three different vibrational configurations (vibrofluidized with Γ=4 formed by A=0.015m and f=8.14Hz; vibrofluidized , Γ=4 for A=0.003m and f=18.20Hz and fluidized bed, Γ=0) using the air velocity between 4 and 6 Umf and temperature between 50 and 70ºC. Through the individual planning of each configuration one can verify statistically the main responses of the system: feed rate, elutriate production, moisture content and particle diameter. For the low air velocities, high feed rates and increased elutriate production were obtained, favored mainly by the vibration amplitude of 0.003mm. In all tests, moisture was obtained below 30%, where the industrial boiler has already been burned efficiently. When evaluating the diameter of the powder for flow and burning, the best conditions were found at high speeds and temperatures and greater amplitude of vibration.
Por una poética de la indeterminación en la narrativa de Samanta Schweblin
(Universidade Federal de São Carlos, 2019-03-15) Spahn, Emilia Magalí; Alves-Bezerra, Wilson; https://lattes.cnpq.br/1602719736498812; https://lattes.cnpq.br/9823016420971499
Esta tesina tiene por horizonte revelar una poética de la indeterminación como constituyente de la narrativa de la escritora argentina Samanta Schweblin (1978). A través de la misma se pretende atender a la configuración de la indeterminación en la construcción textual, al esbozo de lo indescifrable en los relatos, donde algo escapa a un sentido unívoco. La propuesta se sostiene, principalmente, a partir de reflexiones de João Adolfo Hansen (2015) al respecto de las formas ficcionales de la extrañeza. Sus postulaciones, basadas en los aportes freudianos sobre lo ominoso (FREUD, 1919), sobre el contraste entre lo familiar y lo no familiar, y el efecto de indeterminación, componen el soporte teórico a partir del cual se analizan, puntualmente, tres cuentos de la autora, pertenecientes a distintas publicaciones. Los textos analizados son “La pesada valija de Benavides” (2002), “Pájaros en la boca” (2009) y “Nada de todo esto” (2015). A partir de ellos, se expone cómo mencionada poética opera en la configuración de lo extraño, concerniendo al ámbito de los sujetos, vinculado a la transgresión de barreras culturales, sociales, morales e ideológicas. La propuesta tiene por objetivo exponer una constante en la producción literaria de la autora, explicitando mecanismos recurrentes, de los que no es posible dar cuenta acudiéndose apenas a la inscripción genérica de las narraciones de la autora. Por consiguiente, dicha poética se presenta como una alternativa a la divulgada asociación de Schweblin a la literatura fantástica, en la medida en que esta filiación se considera insuficiente para explicar el funcionamiento de los textos en cuestión.
