Percepções de pesquisadores brasileiros sobre o acesso aberto à literatura científica
(Universidade Federal de São Carlos, 2017-05) Furnival, Ariadne Chloe Mary; Silva-Jerez, Nelson Sebastian; https://lattes.cnpq.br/1291482506649810; https://lattes.cnpq.br/7157978490951972
A pesquisa se propôs explorar como várias dimensões do acesso aberto à literatura científica são percebidas por pesquisadores brasileiros, identificando também seus hábitos de publicação, uso e citação de fontes em acesso aberto. A abordagem metodológica foi quantitativa, com aplicação de um questionário a 643 doutores permanentes distribuídos nas universidades brasileiras, oriundos de todos as áreas disciplinares. O questionário foi elaborado com auxílio da plataforma livre LimeSurvey, sendo composto por 29 questões fechadas. Foram recebidos questionários respondidos por pesquisadores oriundos de 31 Institutos de Ensino Superior e Institutos de Pesquisa no Brasil. A estratificação por área mostrou uma distribuição relativamente equilibrada entre os campos de conhecimento, com a maior porcentagem sendo das Ciências da Saúde (21%), seguido pelas Ciências Exatas e da Terra (20,1%), e a menor porcentagem, de 1,1%, de Linguística, Letras e Artes. Os resultados apontaram que a grande maioria dos pesquisadores respondentes detém conhecimento sobre, e apoiam os princípios e algumas ações de acesso aberto, principalmente em relação à publicação de revistas acesso aberto, o que reflete também nos seus hábitos de uso e citação dessas fontes. Comparativamente, o conhecimento e uso de repositórios é menor, e parece haver uma certa confusão em relação ao status de copyright dos artigos arquivados em repositórios. Ficou evidente que os pesquisadores acreditam que somente os postprints deveriam ser disponibilizados em repositórios. O desconhecimento identificado acerca da compatibilidade entre a publicação em revistas “convencionais”, de assinatura e o arquivamento do mesmo artigo em repositórios em acesso aberto aponta a necessidade de maiores iniciativas informativas para esclarecer esses aspectos.

(Universidade Federal de São Carlos, 2017-05-02) Albertini, Jéssica; Rosa-Magri, Márcia Maria; https://lattes.cnpq.br/4166319985147604; https://lattes.cnpq.br/7803960030368793
The indole acetic acid (IAA) is a phytohormone capable of providing fast responses to plant development such as cell elongation and differentiation and division of cells. It is known that exist in the rhizosphere there are yeasts capable of assisting the plant development by the IAA production. In this study, the objective was isolate yeasts of the rhizosphere and select lineages capable of producing IAA; the selected lineage was evaluated for the influence of temperature, pH, agitation, carbon and nitrogen on the production of IAA. For isolation, corn rhizosphere and sugarcane were sampled from the campus area of UFSCar, Araras/SP. The samples were plated on YEPD medium, Sabouraud and BDA. The lineages were selected using colorimetric methodology, with Salkowsky reagent. The best results were evaluated for the influence of factors in the production of AIA, through experimental planning with multivariate analysis. Six yeast strains were isolated; the strain 6S01, identified as Torulaspora globosa, was selected. The results of the multivariate analysis show that among the studied factors, which significantly affected the production of IAA were pH, agitation and nitrogen. The pH showed the greatest influence on production, because it affected significantly at all times evaluated; the highest recorded production values were obtained in the treatment in which the initial pH of the medium was adjusted to 9,0. The highest yields occurred between 24 and 48 hours of incubation, and the maximum production was 217,73 μg/mL. It was observed that, in the tests in which there was no addition of nitrogen source in the culture medium, the production was higher; probably tryptophan provided as a precursor molecule of AIA synthesis was used by tthe yeast as a nitrogen source and was better absorbed in the absence of other sources of the nutrient. It is concluded that the yeast T. globosa (6S01), isolated from maize rhizosphere presents capacity of high production of IAA, with potential for large scale production; the best conditions for the production are in the absence of nitrogen source and in alkaline medium.

(Universidade Federal de São Carlos, 2017-05-02) Rocha, Renata Kühl; Rosa-Magri, Márcia Maria; ; https://lattes.cnpq.br/3962441453324220
Soil is an environment with great microbial diversity. Filamentous fungi and bacteria have been known for decades for the ability to stimulate plant development. Recently, studies have shown that yeasts are also capable of benefiting plants, for example, through the solubilization of inorganic phosphates. This work aims at a better understanding of the ability of rhizospheric yeasts in the solubilization of tricalcium phosphate. It also aims to study the influence of factors (pH, temperature and agitation) in the process. Initially, isolates of corn and sugarcane rhizosphere yeasts were made. The isolates were evaluated for the ability to solubilize tricalcium phosphate in solid medium BDYA. The isolate with the highest solubilization capacity was identified and evaluated for the solubilization capacity of tricalcium phosphate in NBRIP liquid medium at different temperature levels (20, 25 and 30 ° C), initial pH (3, 5 and 7) and agitation (0, 100, 150 and 200 rpm). Solubilization evaluations were also performed at 24-hour intervals, ranging from 1 to 7 days. Six isolates were obtained. All presented a positive result for solubilization. The yeast 6S01 (Torulaspora globosa) had the highest solubilization capacity. After five days, T. globosa solubilized 26 to 35% of the total phosphorus in the NBRIP culture medium. There was no significant difference for any of the environmental parameters tested. Assays performed in periods of 1 to 7 days showed that the yeast solubilized a maximum amount of phosphorus in 48 hours (42%). This makes it interesting for industrial and agricultural applications, since it has a fast solubilization process and can be used in a wide range of conditions. It was possible to understand that a higher cell growth is not related to the efficiency in the solubilization, and that acidification of the medium may be one of the main mechanisms used by yeast in the in vitro solubilization of tricalcium phosphate.
Coloração de Arestas em Grafos Split-Comparabilidade
(Universidade Federal de São Carlos, 2017-05-02) Cruz, Jadder Bismarck de Sousa; Almeida, Sheila Morais de; https://lattes.cnpq.br/9151881548763857; Silva, Cândida Nunes da; https://lattes.cnpq.br/6019111128413167; https://lattes.cnpq.br/2157434731256503
Let G = (V, E) be a simple and undirected graph. An edge-coloring is an assignment of colors to the edges of the graph such that any two adjacent edges receive different colors. The chromatic index of a graph G is the smallest number of colors such that G has an edge-coloring. Clearly, a lower bound for the chromatic index is the degree of the vertex of higher degree, denoted by ?(G). In 1964, Vizing proved that chromatic index is ?(G) or ?(G) + 1. The Classification Problem is to determine if the chromatic index is ?(G) (Class 1 ) or if it is ?(G) + 1 (Class 2 ). Let n be number of vertices of a graph G and let m be its number of edges. We say G is overfull if m > (n-1) 2 ?(G). Every overfull graph is Class 2. A graph is subgraph-overfull if it has a subgraph with same maximum degree and it is overfull. It is well-known that every overfull and subgraph-overfull graph is Class 2. The Overfull Conjecture asserts that every graph with ?(G) > n 3 is Class 2 if and only if it is subgraph-overfull. In this work we prove the Overfull Conjecture to a particular class of graphs, known as split-comparability graphs. The Overfull Conjecture was open to this class.
Capacidade de locomoção de Ololygon Alcatraz (Anura:Hylidae): subsídios para a conservação Ex Situ
(Universidade Federal de São Carlos, 2017-05-02) Lisboa, Cybele Sabino; Brasileiro, Cinthia Aguirre; https://lattes.cnpq.br/2415614509705858; Cruz, João Batista da; https://lattes.cnpq.br/6711198385217623; https://lattes.cnpq.br/3503075011196526
The current global amphibian situation requires the implementation of efficient conservation measures to minimize or stabilize declines and extinctions rates. Ex situ conservation is a complementary strategy to in situ conservation and is mainly used in captive breeding and maintenance of endangered species for possible reintroductions. It is known that certain abilities can be lost after multiple generations in captivity, generating individuals more adapted to the captive environment. Locomotor function is a fundamental trait to survival, therefore, for an ex situ conservation program it is important to know whether the locomotion and metabolic capacities of captive born and wild animals are similar. Thereby, the present study evaluated the locomotor and metabolic capacities of ex situ and in situ populations of Ololygon alcatraz. This species is bromeligenous, endemic to the Ilha dos Alcatrazes (Brazil) and is threatened, categorized as Critically Endangered on the IUCN and Brazilian red lists. The locomotor performance was measured by manual stimulation of the individuals in an arena and the metabolic capacity was estimated by measuring the maximum activity of enzymes responsible for the production of energy for the locomotion activity. Captives born presented greater resistance to exercise when compared to the wild ones, traveling greater distances, jumping more times and spending more time in exercise, besides presenting higher activity of the enzyme citrate synthase. Wild animals had the potential to perform longer jumps and presented greater activity of the enzyme lactate dehydrogenase, which supports this type of exercise. These differences seems to be explained by phenotypic plasticity, arising from the environment in which individuals were created during ontogenetic development. This study evidenced the need to implement some measures to avoid that such differences are fixed in captives born Ololygon alcatraz and do not compromise their survival if they are translocated to the wild, thus subsidizing the species ex situ conservation program.
Estudo das propriedades estruturais, elétricas e ópticas de filmes finos de Niobato de Sódio e Potássio (KNN), fabricados por deposição a laser pulsado (PLD)
(Universidade Federal de São Carlos, 2017-05-05) Burgos Gavelán, Ricky Nelson; Zambrano, Michel Venet; https://lattes.cnpq.br/1830376229286038; Moreira, Fernando Manuel Araújo; https://lattes.cnpq.br/1809254923092721; https://lattes.cnpq.br/4542523190192267
Environmental problems arising from lead toxicity in materials, such as those in lead zirconate titanate (PZT) have stimulate the search for new lead-free ferroelectrics materials with ferroelectric and piezoelectric characteristics comparable to those of PZT. Potassium sodium niobate (KNN) based materials are possible candidates to replace PZT materials in several applications because their high Curie temperature and high piezoelectric coefficients. Development of microelectronics and optoelectronics requires materials with multifunctional properties and low dimensionality, therefore studies in ferroelectric thin films with applications in ferroelectric memories, ferroelectric transistors, photovoltaic devices, electronic modulators, infrared detectors and varistors are necessary. The main object of this thesis, is the synthesis and characterization of morphological, electrical and optical properties of ferroelectric KNN and samarium doped KNN (KNN:Sm3+) thin films, deposited on three diferents substrates SrTiO3, MgO e Si/SiO2) by pulsed laser deposition method (PLD), in addition, a conductive layer of LaNiO3 was deposited on SrTiO3 substrate before deposition of the ferroelectric films for using as electrode and perform electrical characterizations including current leakage, which limits applications of ferroelectric thin films. Finally, photoluminescence measurements of samarium doped films were performed in order to investigate the interaction of this element with crystal structure of KNN, which provides information about possible multifunctional applications.
Made in China / produzido no polo industrial da zona franca de Manaus : o trabalho nas fábricas chinesas
(Universidade Federal de São Carlos, 2017-05-05) Brito, Cleiton Ferreira Maciel; Lima, Jacob Carlos; https://lattes.cnpq.br/9244132532446607; https://lattes.cnpq.br/5852813705553258
This research analyses the Chinese production in the Industrial Cluster of Manaus Free Zone, focusing on the production pattern and work management. In recent years, significant changes have been operating within the global production chain as a result of the massive displacement of Chinese capital towards the various regions of the globe. Brazil and, more specifically, the Amazon has been one of the main destinations of these Chinese investments. An empirical proof of these metamorphoses of global capital is the arrival of a set of Chinese factories at the Industrial Cluster of Manaus (PIM) from the beginning of the year 2000. In order to understand the meaning of this on the organization of local work, especially in relation to the process of productive restructuring developed in the last years, this research sought to organizationally map out four Chinese factories. Quantitative and qualitative data were produced and gathered together from workers, managers, managers of public and private institutions, and Chinese expatriates. The research findings show that the Chinese, on the one hand, incorporated the local production pattern but, on the other hand, reshaped labour management. Such remodelling I called "taylorization with Chinese characteristics", which operates under the duality of being, at the same time, Made in China, but Produced at the Industrial Cluster of Manaus. As a fundamental element of this process, it was observed that strong socio-productive linkages between parent-subsidiary generate fragile socio-productive links in the Industrial Cluster of Manaus, implying high control of the Manauara workforce and Chinese expatriates. In spite of this, there has been a process of "appropriateness / injunction" that causes some "Chinese characteristics" to be deepened while others have to undergo transformations.

Eleição de líder com qualidade de serviço para o modelo falha-e-recuperação
(Universidade Federal de São Carlos, 2017-05-05) Reis, Vinícius Angiolucci; Vieira, Gustavo Maciel Dias; https://lattes.cnpq.br/9020007815886406; https://lattes.cnpq.br/1535333547015731
A distributed system is a set of processes and links that is desgined to provide computing power and data persistency, even on the presence of failures. To encapsulate the abstraction of time and to determine which processes have currently failed, these distributed systems are based on unreliable failure detectors, which in its turn are used as a leader election service. Many works are dedicated to analyze the quality of service (QoS) of failure detectors, but a few of them has analyzed the QoS of a leader election algorithm. In this work, we present the NFD-L leader election algorithm, designed to work on crash-recovery distributed systems and to follow the QoS specification defined by Chen, Toueg e Aguilera (2002). We used NFD-L to elect Paxos coordinators for a replication framework and compared the observed QoS for NFD-L with the behavior of the framework native leader election algorithm that is not designed to explicitly meet any QoS requirement.
Análise do desempenho do leito vibrofluidizado na secagem de pasta
(Universidade Federal de São Carlos, 2017-05-05) Costa, Ariany Binda Silva; Freire, Fábio Bentes; https://lattes.cnpq.br/8937961078558996; Freire, José Teixeira; https://lattes.cnpq.br/2270677706718167; https://lattes.cnpq.br/9518055204202962
The agitation promoted by the vibrofluidized bed allows the incorporation of several unitary operations such as granulation, coating of particle, drying of grains, and the drying of pasty materials. However, it is necessary more studies about the drying of paste in this equipment, since according to the work of Daleffe (2005) and Meili (2009) it was verified that a same dimensionless vibration number (Γ) presented different dynamics behaviors and influenced in distinct ways in the process. To understand more about the interference that the vibrational parameters may exert in this type of operation, that the goal of this present work was to develop a more detailed study on the drying of skimmed milk in vibrofluidized bed, varying the intensities of agitation imposed to the bed, two Amplitude (A) from 0.003m and 0.015m combined at frequencies (f) ranging from 100 to 1100 RPM. Thus, firstly, it was analyzed the influence that the vibrational parameters exercised on the characteristic curves of the pressure drop and the standard deviation of pressure drop in function of the superficial velocity of the fluid (Us), when the bed was constituted with glass beads with the diameters of 0.00119m, 0.00219m, and 0.00319m. Thereafter, water evaporation tests were performed to determine the size of the inert material and the experimental conditions that would be used in the paste drying trials. For the drying of the skimmed milk has been used glass beads with 0.00319m of average diameter, air temperature of 100 ° C, surface velocity of 20% higher than minimum fluidization velocity (Umf), different agitation intensities and different paste feed rates. During the experiments, the influence of agitation on the dimensionless pressure drop, air temperature at the bed outlet, relative air humidity at the bed outlet, powder moisture content, powder production rates and powder accumulation rates were analyzed. Analyzing the obtained results, it may be verified in the two amplitudes that the increase of the agitation intensity, through the increase of the frequency, allowed the use of higher maximum feeds rates of skimmed milk in the equipment. It was also observed, for the values of Γ almost constant with different combinations of A and f, that the agitation with amplitude of 0.015m resulted in the greatest variations of pressure drop during the process, in the lower relative humidity levels, in the higher powder production rate and higher powder accumulation rates at the exit of the cyclone. In this way emphasizing the importance to inform A and f to characterize the implemented vibration in the vibrofuidized bed. From these experimental data was designed a hybrid CST / Neural to describe the heat and mass transfer phenomena that occurred during the drying of skim milk. The results showed that the proposed model presented a great agreement with the experimental data, assuming that the vibrofluidized bed behaved as a perfectly stirred tank.
Modificações da técnica de corrida : aspectos biomecânicos e clínicos em corredores com e sem dor patelofemoral
(Universidade Federal de São Carlos, 2017-05-05) Santos, Ana Flávia dos; Nakagawa, Theresa Helissa; https://lattes.cnpq.br/3020771286419217; Serrão, Fábio Viadanna; https://lattes.cnpq.br/8137335642635433; https://lattes.cnpq.br/2621235843235000
Every year, up to 70% of recreational runners reported some musculoskeletal injury. Patellofemoral pain (PFP) is one of the most common injuries in these athletes. It has been reported that gait retraining may have a beneficial effect on the lower limb biomechanics and consequently may reduce the patellofemoral joint overload. However, the information regarding biomechanical and clinical effects after a training protocol in PFP runners and, the comparison between different techniques in a same cohort in order to identify the most effective are sparse. Therefore, the objectives of this thesis were: to evaluate the immediate and long-term effects of gait retraining of kinematic, electromyography, pain and function in PFP runners and; to verify the effectiveness of three running techniques on the patelofemoral joint stress in healthy runners. The three running techniques were: forefoot landing, step rate increase by 10% and forward trunk lean. Kinematic, kinetic and electromyography analysis were done. To assess pain and function, the visual analog scale and two self-reported questionnaires were used. The results showed that the three running techniques reduce pain intensity and improve function in PFP runners after 2 weeks of a supervised gait retraining and, these improvements are maintained 6 months after the intervention. The gait retraining increased the muscle pre-activation before the initial contact. Forefoot landing technique was the most effective condition for reducing patellofemoral joint loading.

Doctor Who, a British series created and produced by the BBC since 1963 has been devoted as one of the oldest and most successful series of fiction for television. The series has set its course and achieved cult status, becoming the success it is today with an extensive amount of episodes and seasons and a large expansion of its narrative universe to other media such as movies, comics, literature, digital and analog games. The expansion of a work brings a series of obstacles, a vast narrative maintained for so long and in so many media, undergoes several changes with the passage of time, the fans can also change or have different expectations. Nevertheless some series like Doctor Who, manage to remain firm and coherent over time. These series can find and construct a solid identity that is interesting and acceptable to its fans, this identity is related to the archetypes of the fictional universe of the series and is what often guides the narrative direction and the migration of this narrative to other media, this study aimed to analyze and punctuate the elements that define this identity of Doctor Who and how this can contribute to the production and study of vast transmedia narratives.
Relações entre infância, escola e religião : etnografia dos Baniwa do médio Içana
(Universidade Federal de São Carlos, 2017-05-05) Marqui, Amanda Rodrigues; Cohn, Clarice; https://lattes.cnpq.br/1714080901123094; https://lattes.cnpq.br/1696584969032916
This dissertation is about the relations of childhood, school and evangelical religion of the Baniwa people, who live in the Upper Rio Negro, northwest Amazon. From ethnographic experience in communities of the Middle Rio Içana aspects of Baniwa sociality in the formation of their children are addressed in this dissertation, considering the school and the evangelical religion contexts. The school context is one of the common threads of the ethnographic narrative since the entry into the field happened after an invitation received from the Moliweni school in Vista Alegre community located in the Cuiari River within the scope of the UFSCar Observatory of Indigenous School Education. The religious and school events in Baniwa communities of the Middle Içana demonstrate the importance of religion in its social organization as well as its influence in the debates regarding differentiated Baniwa school education. Thus, this ethnography describes the formativa process of children anf young in their communities in school and religious spaces to understand the meaning of good living in the Baniwa communites of the Middle Içana
Avaliação do potencial antimicrobiano e leishmanicida de materiais orgânicos derivados da base de Schiff N,N-bis’(Salicilideno)-1,2-fenilenodiamina
(Universidade Federal de São Carlos, 2017-05-05) Soriano, Bianca; Sousa, Cristina Paiva de; https://lattes.cnpq.br/9002619114161319; https://lattes.cnpq.br/6431092009628550
Bacteria and fungi are the main etiological agents potentially causing health care-related infections and the fourth leading cause of death, according to the WHO. Parasitic agents such as Leishmania infantum chagasi, the causative agent of leishmaniasis, neglected and endemic disease, have treatments that are not always eﬀective and have serious side eﬀects. Resistance to antibiotics, antimycotics and leishmanicides, has increasingly induced bioprospecting and synthesis of new substances with pharmacological properties. The Schiﬀ bases, especially those derived from the N, N’-bis (salylcilidene) -1,2-phenylenediamine linker, also known as Salofen, have been studied in order to demonstrate the physical, chemical and biological properties due to Variety of potential technological applications. The objective of this work was to evaluate the biotechnological potential of the Schiﬀ N, N’-bis (salylcilidene) -1,2-phenylenediamine (Salofen) base derivative in relation to the antimicrobial and leishmanicidal activity. Agar diﬀusion techniques and microdilution assays were used for bacterial and yeast studies, and the colorimetric method with Alamar Blue® for Leishmania tests at 24 and 48 hours. Inhibition halos were observed for all microorganisms tested, with the highest mean halos (30 mm) for Candida albicans. Dilution assays have shown promising results, with inhibition rates above 90%, emphasizing better Gram-negative efciency. The leishmanicidal eﬀect was also observed with IC50 at 1.06 mg.mL−1 at 24 hours and 0.66 mg.mL−1 at 48 hours. Thus, the data collected suggest that the Schiﬀ base tested has an antimicrobial and leishmanicidal potential of the compound studied, suggesting a biotechnological application.
Regressão não linear quantílica para classificação de sítio em povoamentos de Eucalyptus sp.
(Universidade Federal de São Carlos, 2017-05-09) Santos, Carlos Juliano; Thiersch, Cláudio Roberto; https://lattes.cnpq.br/8791966697254106; https://lattes.cnpq.br/6499460352099237
The productive capacity is conventionally estimated by anamorphic or polymorphic calculated site curves; however, these curves have some limitations. Due to these limitations, the objective of this work was to evaluate the creation of growth curves for site classification by the nonlinear quantile regression method and to compare them with the curves generated by the algebraic difference method. The database was collected in two mesoregions of the state of São Paulo (Paulista and Bauru Metropolitan Macro), with 460 measurements in 98 plots with distinct periods in Eucalyptus sp. The site curves were adjusted according to the Chapman-Richards model using the algebraic difference method for anamorphic and polymorphic curves and nonlinear quantum regression (RNLQ). The results of this work allowed to conclude that the site curves adjusted by the RNLQ method are superior to the curves generated by the algebraic difference method by graphical analysis of the residuals with smaller ranged of the errors and greater homogeneity and residual standard error with lower values in the classes in general.
Propostas de pagamento no estudo de matemática financeira : análise de uma abordagem prática
(Universidade Federal de São Carlos, 2017-05-09) Francisco, Marcelo Sabbadini; Malagutti, Pedro Luiz Aparecido; https://lattes.cnpq.br/5462523657624050; https://lattes.cnpq.br/9478680093249519
The objective of the project and research was to apply and conjecture about a practical approach to the study of payment methods, using commercial proposals of students' daily routine of a technical course in the management area. Assessing the historical and conceptual aspects, as well as associating them to students' daily life, in order to assist the student and the technical future in their future commercial transactions, whether private or professional, and enable them to conceptually and critically evaluate the methods of payment offered in the acquisition of a property, were the main strands developed in the application of the research proposal, as recommended by various scholars in the area of financial education, among them GRANDO and SCHNEIDER (2011). The work was developed, according to the theoretical presuppositions of didactic engineering, in stages, among them the study of conceptual and historical aspects of the amortization system, analysis of everyday situations and the application of questionnaires. The researcher professor conducted the study in the 1st module of technical course in finances at a state technical school in Jaú city. The results obtained in the questionnaires from the students finances course were compared with the results from the students in the first module of the management technical course. However in the management class the content was developed by exposing the theory and solving problem situations. The guiding question for our research was: “Does a practical approach to the study of financing systems help the student by comparing the methods of payment opt for the most economical option?” The analysis of the results presented a favorable framework for the proposal of a practical approach, prioritizing the use of everyday situations, to the study of payment methods besides it offered a more critical learning to the detriment of a reproductive bias normally observed in the teaching of financial mathematics.
Efeitos de um derivado semissintético do [6]-gingerol na autofagia e apoptose em células de câncer de mama
(Universidade Federal de São Carlos, 2017-05-09) Dulcey, Liany Johanna Luna; Cominetti, Márcia Regina; https://lattes.cnpq.br/3725318894555272; https://lattes.cnpq.br/1841833705087719
In this work, we describe a semisynthetic derivative of [6]-gingerol called SSi6, which induces cytotoxic effects on the MDA-MB-231 breast tumor, showing a greater selectivity for these cells when compared to the non-tumor MCF-10A , In addition, the substance was determined to induce autophagy and apoptosis in tumor cells, with less pronounced effects on non-tumor cells. The coexistence of both events (autophagy and apoptosis) was demonstrated by flow cytometry, which evidenced an increase in the percentage of apoptotic cells after 24 hours of treatment, these results were also confirmed by the analysis of the gene and protein expression of caspase-3 using Real-time PCR and western blotting respectively. Induction of autophagy in SSi6-treated cells has been demonstrated through acid vesicle organelle (AVOs) detection assays and the expression of genes encoding the LC3-I and II microtubule-associated proteins to quantify the abundance of autophagosomes in MDA-MB-231 cells. Thus, these results indicate that SSi6 has the potential to induce autophagy and apoptosis, as well as antitumor and antimetastatic properties in MDA-MB-231 breast tumor cells.
Transformação e permanência : regionalismo e representação da mulher em Faca, de Ronaldo Correia de Brito
(Universidade Federal de São Carlos, 2017-05-10) Santos, Élide Mendonça dos; Pellegrini, Tânia; https://lattes.cnpq.br/0280434883580627; https://lattes.cnpq.br/1860491964988052
This work aims the investigation of the permanence of a contemporary Brazilian regionalism tradition, based on some tales of the book Faca, published in 2003 by the cearense writer Ronaldo Correia de Brito. These tales are: “A espera da volante”, “Faca”, “Redemoinho”, “A escolha”, “Mentira de Amor” e “Cícera Candoia”. It is proposed to line a possible trajectory for a women’s representation in different kinds of regionalism that comes out in different moments in our literary panorama, basing on canonical works about this subject. Our own work is also based on the critical theory studies to comprovate our hypotheses and objectives. Our choice for this work is justified by the fact that the feminine characters, established in the author’s universe, revisit and reiterate some tradicional codes about genre, but also include new codes that are related with the present time. It reaffirms, in this way, the own survival of the recent regionalism, once that the characters assumed contravention roles, different from that is verified in ulterior phases, engendering the turn of the XIX century. Besides, our hypothesis is the effect of transgression, subversion and punishment, always present in stories and characters in the regionalism expression; it has coming a bit of consuming in the contemporary, to indict, in a certain way, the sociocultural transformations lived in our time.

In this study called Linguistic mechanisms and intersubjective relations in textual production: enunciative activities in the teaching practice, the aim is to recall questions from the Master’s degree, such as the difficulty that students have to insert notions of qualification as explicit marks of intersubjective regulation (commented world) in their textual productions. Analysing, now, a practical work to be done in school contexts and considering the difficulties observed in the students’ textual production, we have the objective to i. explore more deeply the process of constitution of enunciative plans which involve linguistic mechanisms as marks of intersubjective regulation, especially the appreciative modality, which marks the enunciator’s point of view – favourable or unfavourable – about a content that is constructed linguistically; ii. determine and analyse the use of the appreciative modality in a corpus constituted of narrative texts, especially fables; iii. propose linguistic practices to be applied in the exercise of textual production aiming to explore, in the language teaching, the language process which can promote the students’ linguistic-cognitive development. It is used in this work the Theory of Predicative and Enunciative Operations proposed by the French linguist Antoine Culioli.

Sustainable development raises at present days a number of challenges to manufacturing, precisely in order to make production more sustainable, equating economic and financial issues with environmental and social issues. Cleaner Production represents one of the approaches which can be used by manufacturing companies in the attempt to achieve this purpose, rightfully represent this a strategy oriented to the reduction of negative impacts arising from production processes in all its extension. As a direct result of the implementation of cleaner production practices, enhances the efficiency of the production process, thus increasing competitiveness of enterprises, whether in terms of increases in manufacturing capacity, both in terms of better prospects of generating financial results. However, in the case of the Brazilian context, are relatively sparse theoretical-empirical evidence that greater intensity as the implementation of cleaner production practices on the part of corporations effectively shown able to influence your financial performance. Under such circumstances, the objective of the present study is to assess whether the greater or less intensity about the implementation of cleaner production practices by manufacturing companies listed on the BM&FBOVESPA shown effectively able to provide significant differences in terms of financial performance. To this end, a survey research was undertaken by the manufacturing companies listed on the BM&FBOVESPA, whose research instrument was constituted in the questionnaire. The collected data were subjected to statistical analysis by means of appropriate software to such purpose, by use of Multivariate Statistical technique called multiple Linear Regression. Finally, the survey results point to the perception that some of the cleaner production practices seem to influence corporate financial performance, profitability, and profitability, than be seen to be viable your implementation under the economic-financial point of view.
