A diversidade de lagartos na Caatinga é mediada pelos térmitas?

Intending to explain the extraordinary lizard coexistence levels found in Australian deserts, Morton & James (1988) figured out a hypothesis which defends that the termite diversity would bring about lizard radiation. This study aims to verify the validation of that hypothesis in Caatinga lizard assemblages. This study also objectives verifying if the termite defense mechanisms influence their consuming levels by lizards and if this pattern differs between different lizard lineages. Termites were collected using a standardized sampling protocol of termites. Besides using haphazard sampling, we collect lizards with 108 pitfall traps in each area. Intending to check the linkage between the termite and lizard assemblages, the lizard stomach contents were analyzed and then a canonical correspondence analysis was performed. The presence of nonrandom patterns of diet overlap among the lizard species was also examined. Aiming to check if the defense mechanisms of termite influence their consuming pattern by lizards it was performed a laboratory experiment where termite with different defense mechanisms were offered to lizards of two different lineages. We verified that lizard assemblages do not consume termites according to termite abundance in ecosystems. Furthermore, mean niche overlap lizard species did not differ significantly from that expected by chance. We found that termite chemical defense mechanism does influence the termite s pattern consuming by lizards. These results do not corroborate premises which support Morton & James hypothesis (1988) and point out that lizard do not chose termites based on their abundance, but, trying to avoid consuming termites which exhibit chemical defense mechanisms. This defense mechanism, however, may not be the only explanation to patterns of termite s consuming by lizards.

Paradigma constitucional brasileiro da livre concorrência e da defesa do consumidor face às estruturas de poder no mercado

The Federal Constitution of 1988, when taking care of the economical order, denotes special concern in the abuses of the economical power and the disloyal competition. The mark to mediate of all this is, in fact, the defense and the consumer's protection, once this is final addressee of whatever if it puts at the consumption market. The coming of the Law 8.078/90, Code of Protection and Defense of the Consumer, inaugurates a time of effective concern with the homogeneous individual interests originating from of the consumption relationships. In this point, the focus of main to face of the present work lives, in other words, the protection of the right to the individual property, especially manifests in the exercise of the trade freedom that keeps direct relationship with the respective social function the one that is destined. The code of the consumer's defense doesn't just take care of this, but also of the other star of the relationships of the consumption. When affirming in the interruption VI of the art. 4th that the national politics of those relationships, finds ballast in the prohibition and repression efficient of all of the abuses committed in the consumption relationships, keeping inherent relationship-causality in the economical order, sculpted for the article 170 in the Constitution of 1988. In the generic plan, the mark of the present work is to question concerning the limits of the trade freedom and previsible collisions with protection norms and the consumer's defense, as well as factual convergences of those small systems, especially in what he/she refers to the innate interests to the suppliers. In the specific plan, we aspirated to identify the protection device-commands to the actors of the trade relationship, capable to guarantee the free competition in a global economy of market, seeking especially the Well-being, for soon afterwards, in an analytical perspective, to discover the possible applications that it holds the Federal Constitution, in headquarters of economical freedoms. It was observed that the consumer today doesn't need only of laws that their needs, fruit of the vulnerability that it is him/her meditate innate. He/she lacks, yes, of effective mechanisms that prevent lesions that can be them impinged by the suppliers at the time in that you/they are useful to repair the damages when happened, punishing the author of the damage

Ave! Mossoró! : os mecanismos discursivos sobre o episódio da resistência ao bando de Lampião

This thesis has as objective the interdiscursive relations in the process of language construction in use in the poetic and in the journalistic spheres, with the purpose of perceiving how the genre news is constituted in different fields of social activity, as well as to analyze the argumentative processes that structure the written discourses about the resistance episode to the group of Lampião in Mossoró in the year of 1927. The corpus of the research is constituted by the news of the period informed in the printed newspapers: Correio do povo and O Nordeste, both from Mossoró/RN, and the narratives presented in the cordéis de acontecido : Mossoró in the resistance to the group of Lampião; Lampião in Mossoró in 1927, and Mossoró attacking to the group of Lampião, all potiguar poets. The analysis of the texts had as theoretical background the studies of: The texts analysis had as theoretical background The Discourse Analysis; The Argumentation Theory and the studies about Discourse Genres. We focused our discussion in the emphasis given to the news in the discursive perspective of the social-historic memory constructed in the cordéis, from ideological values (political, economical, religious etc.) that pass to be a fundamental element in the constitution of the image of the resistance. Methodologically, this is a documental research, since it makes use essentially of the written document. Regarding to the nature of the data, the research is characterized as a qualitative one. In the analysis, we considered the argumentative techniques adopted in the defense of the thesis, the meaning effects suggested, and the genres mentioned, that revealed to us the manner in which the episode was informed by the newspapers and the cordéis. That way, we affirm, based on the positions assumed by the announcers of the genres analyzed who defended clearly positions in favor of the defense of Mossoró, that the relation between both is captured interdiscursively, since they are asked by the same ideology, and converge to the same discursive formation, defending identical positions, and structuring their discussions with resembling argumentative techniques, reason by which take us to believe that the discourse presented in that social activity demonstrates and develops traces of a manipulation of the subject. In this case, the discursive construction of the text points towards determining standard of repetition, since the linguistic context is characterized in the journalistic field, and in the poetic field assuming, in the first instance, a local expression

Relações entre mecanismos de coordenação e controle com desempenho organizacional: um estudo nas instituições públicas de ensino médio de Natal

This research aimed at relating coordination and control forms to organizational performance. The multicase study was applied in two public high schools: Centro Federal de Educação Tecnológica do Rio Grande do Norte and Floriano Cavalcanti. In order to accomplish these objectives, it was developed a qualitative analysis and considered coordination and control forms of several authors. Also was considered Sander´s (1984) model of organizational performance. The mentioned model considers two criteria to analyze organizational performance: one instrumental (efficiency and efficacy) and other substantive (effectiveness e relevance). The research attempts to show the importance of balancing these criteria in a way that effectiveness and relevance becomes more important at schools. It was proven that the use of bureaucratic coordination forms has the power to influence the evaluation on the instrumental technique. At the same time, it was observed that the use of mechanisms based on the autonomy of the school is related to efficiency and efficacy. The object of this research can be considered successful

Modelagem matemática para o transporte de partículas sujeitas a múltiplos mecanismos de retenção

Discrepancies between classical model predictions and experimental data for deep bed filtration have been reported by various authors. In order to understand these discrepancies, an analytic continuum model for deep bed filtration is proposed. In this model, a filter coefficient is attributed to each distinct retention mechanism (straining, diffusion, gravity interception, etc.). It was shown that these coefficients generally cannot be merged into an effective filter coefficient, as considered in the classical model. Furthermore, the derived analytic solutions for the proposed model were applied for fitting experimental data, and a very good agreement between experimental data and proposed model predictions were obtained. Comparison of the obtained results with empirical correlations allowed identifying the dominant retention mechanisms. In addition, it was shown that the larger the ratio of particle to pore sizes, the more intensive the straining mechanism and the larger the discrepancies between experimental data and classical model predictions. The classical model and proposed model were compared via statistical analysis. The obtained p values allow concluding that the proposed model should be preferred especially when straining plays an important role. In addition, deep bed filtration with finite retention capacity was studied. This work also involves the study of filtration of particles through porous media with a finite capacity of filtration. It was observed, in this case, that is necessary to consider changes in the boundary conditions through time evolution. It was obtained a solution for such a model using different functions of filtration coefficients. Besides that, it was shown how to build a solution for any filtration coefficient. It was seen that, even considering the same filtration coefficient, the classic model and the one here propposed, show different predictions for the concentration of particles retained in the porous media and for the suspended particles at the exit of the media

Proteômica comparativa de linhagens celulares humanas expostas a estresse oxidativo induzido por riboflavina fotossensibilizada

Reactive oxygen species (ROS) are continuously generated and can be derived from cellular metabolism or induced by exogenous factors, in addition, have the capacity to damage molecules like DNA and proteins. BER is considered the main route of DNA damage oxidative repair, however, several studies have demonstrated the importance of the proteins participation of other ways to correct these injuries. NER enzymes deficiency, such as CSB and XPC, acting in the damage recognition step in the two subways this system influences the effectiveness of oxidative damage repair. However, the mechanisms by which cells deficient in these enzymes respond to oxidative stress and its consequences still need to be better understood. Thus, the aim of this study was to perform a proteomic analysis of cell lines proficient and deficient in NER, exposed to oxidative stress, in order to identify proteins involved, directly or not, in response to oxidative stress and DNA repair. For this, three strains of human fibroblasts, MRC5-SV, CS1AN (CSBdeficient) and XP4PA (XPC-deficient) were treated with photosensitized riboflavin and then carried out the differentially expressed proteins identification by mass spectrometry. From the results, it was observed in MRC5-SV increase expression in most of the proteins involved in cellular defense, an expected response to a normal cell line subjected to stress. CS1AN showed a response disjointed, it is not possible to establish many interactions between the proteins identified, may be one explanation for their sensitivity to treatment with riboflavin and other oxidants and increased cell death probably by induction of pro-apoptotic pathways. Already XP4PA showed higher expression of apoptosis-blocking proteins, as there was inhibition or reduced expression of others involved with the activation of this process, suggesting the activation of an anti-apoptotic mechanism in this lineage, which may help explain the high susceptibility to develop cancers in XPC individuals. These results also contribute to elucidate action mechanisms of NER in oxidative damage and the understanding of important routes in the oxidative stress correlation, repair and malignant tumors formation

Efetivação da garantia de defesa no estado constitucional de direito: colisão entre o poder punitivo e garantia de defesa

The domination of the violence for the Rule of law awakened a tension between the practice of the punitive power and the right to counsel. However, throughout the recent history of the Criminal law, this shock of forces has been determined for the punitive power. In this perspective, the present work intends to submit the guarantee of defense to a critical judgment, in search to conciliate its content to the Constitutional State of Right. For in such a way, it will be necessary to recognize the disequilibrium of the situation, but without considering the superiority of any of these elements. The State in such a way must fulfill the function to punish the culprits as to acquit the innocents. Despite the law is far from obtaining a harmonious speech, it is necessary that the defense guarantee coexists the punitive power as part of an only public interest, which is, to make criminal justice. In such a way, the existence of a sustainable balance between the punitive power and the guarantee of defense depend on the minimum interference of Criminal law and, also, of the judicial position in the concrete case. The present work faces, therefore, the moment of crisis of the Criminal law, consolidated with the advent of a new way of thinking according to the procedural guarantees, that will demand the overcoming of the old concepts. The Constitutional State of Right not only constitutes an efectiveness of the regime of the right to counsel, but in a similar way it searchs to accomplish the right of action and criminal justice as a whole. Knowing that the philosophy of the language raises doubts on the certainty, the truth and the judgement, it is imposed to understand that the defense guarantee is no more about a simple idea, but, in the crooked ways of the communication, we intend to find what the judge s function is when he faces this new reality

Acesso à justiça enquanto direito fundamental: efetivação pela defensoria pública

The Federal Constitution of 1988 is recognized for its enlargement in the face of large amount of provisions that make it up, among which many are fundamental rights. The fundamental rules set up the foundation of a democratic state, however, are the necessary legal mechanisms to be effective, its exercise is not enough merely to state them, but to offer ways for them to stop being just written standard on paper, and come to be viewed and exercised day-to-day. In this sense, access to justice presents itself in our times, as a cornerstone for a just society dictates. In this light, access to justice can be seen as the most fundamental of rights, which translates as instruments able to safeguard the fundamental rights not only against the action/omission violating the state but also the very particular. Furthermore, access to justice within the legal country, is not right for everyone, despite the willingness of the Citizen Charter in its article 5, paragraph LXXIV, ensuring that the State shall provide full and free legal assistance to those in need. More than half of the population lives in poverty and can´t afford to pay legal fees or court costs as well as a bump in their own ignorance of their rights. The judiciary, in their primary function, is in charge of trying to correct the violation of the rights, intending to effect a true distributive justice, serving as a paradigm for the promotion of substantive equality of human beings, however, is difficult and tortuous access Justice for those without financial resources. In this vein, we present the Public Defender, as keeper of the masses in its institutional role, defending a disadvantage, in the words, as a mechanism for effective access to justice, ensuring therefore fundamental rights. Public Defenders arise at the time or much discussion highlights the priority of actual access to justice, custody, therefore, intimate bond with the pursuit of fundamental rights, in which, that advance the broad range of rights, without whom could defend them or guardianship them

Defensoria pública e sua legitimidade à tutela jurídica dos direitos humanos

The realization of human rights is a prerequisite to the development of peoples, this requires legal mechanisms and techniques to its consistent and effective promotion, protection and fulfillment. So, agree that there is an institution or public agency created for the purpose of protecting those who suffer most in the face of human rights violations: the needy. In Brazil, among other institutions and public agencies, the responsibility of the Public Defender to promote the protection of human rights. The constitutional system recognizes the institution in its essence the role of the state court, whose duty is to provide guidance and legal defense of the needy. The legal system as a whole sufraga the relevance of the Ombudsman as a mainspring of human rights. In the prison system, with the ultimate regulatory changes, such as Law 12.313 of 2010 which introduced changes to the Law 7.210 of 1984, the institution must ensure the correct and humane enforcement of sentences and the security measures pertaining to the needy. With the Complementary Law 132 of 2009, to systematize other duties of the Public Defender, highlighting their contribution to the movement of access to justice. Within the OAS, to adopt Resolution 2656, 2011, characterizing, with ruler and compass, the relevance of the Ombudsman access to justice and protection of human rights. In this step, the present study concerns the role of Defender in the legal protection of human rights, through monographic and deductive methods, as there remains a technical and theoretical connection between these two points themed legal phenomenon, since the rights humans, especially after the second half of the twentieth century, form the basis of the legal system of the major Western nations in the world. This led, therefore, the emergence of technical and legal institutions aimed at realizing human rights. This applies to the Defender. Access to justice and public service provision of legal assistance are human rights, therefore, essential to humans and necessary for social inclusion. Countries such as Brazil, marked by social inequality, depend on the structuring of institutions like the Defender, designed to promote citizenship to the Brazilian people

A aplicação do acordo sobre subsídios e medidas compensatórias pelo estado brasileiro

The Multilateral Trading System has evolved and presented new international mandatory rules to States. Along with the World Trade Organization constitutive treaty, Brazil has incorporated the Agreement on Subsidies and Countervailing Measures (ASCM) in the national legal system. That treaty limits de scope of subsidies concession by governments since this practice can constitute a mechanism of commercial disloyalty, affecting national industrial development in the importing country. At the same time, the multilateral agreement grants defense legitimate instruments to States, among them the possibility of domestically and unilaterally imposing countervailing measures to subsidized products that enter the national territory. Since the issue concerns both international and domestic level in complementary grounds, this research, besides investigating the treaty related obligation, aims at studying the national legal fundaments to ASCM s application by the Brazilian State. Therefore, the essential point resides in the State s conduction of its international trading and also in its available and constitutionally established mechanisms of economic intervention. State s regulating power reveals itself as a fundamental prerogative to succeed in the internalization of international agreement s requirements in the domestic legal system, which represents a basic prerequisite to the implementation of countervailing measures. Once the whole normative outlines are apprehended, this study shall scan the administrative process of trading defense main elements, along with the means of controlling public administration acts. The action taken by the public organs that directly intervene in foreign trade shall be analyzed as well, so as to enable reasoning if the unilateral application of countervailing duties by the Brazilian State is happening on legitimacy grounds

Mecanismos sócio-genéticos da representação social de trabalho docente por grupos de licenciandos de física e de química da Universidade Federal do Rio Grande do Norte

This research aims to understand the social representations Teaching Work in groups of undergraduate students of Physics and Chemistry of the Federal University of Rio Grande do Norte. For this, the proposal was based on the three theoretical and methodological consensus Carvalho (2012) in the explanation of socio-genetic mechanisms constituents of dynamic consensus that has functionality to your organization. It Was used to achieve this goal, the theoretical-epistemological Serge Moscovici (1978, 2003), Jodelet (2011), Wagner (1998,( 2011) and Carvalho (2012). The corpus analyzed results from a qualitative and quantitative research, developed in three stages. The first two (2) questionnaires to fifty (50) of each undergraduate course, a questionnaire and another profile for collection of free associations concerning motes inductors "Give Lesson," "Student" and "Teacher". The second step in the procedure Multiple Classifications, Roazzi (1995), aimed for another thirty (30) undergraduate students for each course, as well as Document Analysis of Educational Projects Curriculum courses in Physics and Chemistry. The data analysis of the first stage focused on descriptive statistics and frequency and average order of the words associated with motes inductors. The results from the Multiple Classification Procedure submitted to multidimensional analysis (MSA multidimensional scalogram analysis) and SSA (Similarity Structure Analysis), were interpreted by the theoretical and methodological proposal of the three consensus, supported by analysis of the rhetorical nature of justifications classifications and categorizations of words, boosted in times of application of Procedure Multiple Classification. The data revealed that the groups surveyed were the same Social Representation with specific dynamic consensual. Thinking Teaching Work for these groups it is considered in three dimensions: the BE-DO-HAVE of teaching. In the group of Physics consensus was clear semantic, which expressed a dynamic in which the interpretations of "Teaching Work" peacefully coexist on perceptions of two concepts: An identity around the "BE" "Teacher" or "BE" "Educator" and the other, how they think about professional development. The type of group consensus Chemistry pointed to a consensual logic hierarchical order in which the gradual between the elements of BE-DO-HAVE attested conflicts and disagreements about the perceptual object "Teaching Work", around what value most, whether they are the attributes of personal or professional-technical dimension of teaching, in the course of professional development. The thesis to explain the mechanisms of socio-genetic Representation Social Teaching Work by theoretical and methodological proposal was confirmed

Os conselhos como mecanismos de democratização da política educacional :participação e poder de decisão nas ações do Conselho de Controle Social do FUNDEF no município de Parnamirim/RN

This study board the FUNDEF social control council implementation in Parnamirim/RN city, concerning their representatives participation in the accompaniment (decision power) in resort, in front of governmental politics of decentralization, unleashed in 90´s, seen in decentralization process needs the society participation in decisions of educative institutions and represent an efficient way of solve the problems difficult the educational management actions. For this, the council creation of Brazil manager configure, since the 80´s, detaching, and the single characterizing, in actual context. The objective is raise pertinent questions of thematic of representatives members participation of collegiate organs, evidencing the decision power of these, in public resource control. The theory-methodological referential the literature treat the participation and power decision of FUNDEF social control decision, such as politics directrix that rules this council. It utilizes as proceeding of collecting data the semi-structured interview and analyze of meeting register to understand the empirics of council implantation in this city, in view of that the electoral process configured in 2003, showed as a innovation, because the counselor is indicated by the local public power representatives (in this case the education municipal secretary). The research result show the representatives have difficult, to accompany the FUNDEF resources amount, particularly in concern in the financial resources (ratio) over plus. Finally, emphasize the importance of democratization in the relations between the state and civil society, elucidating and exciting reflections a: democratic participation in control of public recourses for education, educational management and civil society mobilization in access of public and cultural cash which the citizen has rights

Mecanismos de segurança para um sistema cooperativo de armazenamento de arquivos baseado em P2P

Previous works have studied the characteristics and peculiarities of P2P networks, especially security information aspects. Most works, in some way, deal with the sharing of resources and, in particular, the storage of files. This work complements previous studies and adds new definitions relating to this kind of systems. A system for safe storage of files (SAS-P2P) was specified and built, based on P2P technology, using the JXTA platform. This system uses standard X.509 and PKCS # 12 digital certificates, issued and managed by a public key infrastructure, which was also specified and developed based on P2P technology (PKIX-P2P). The information is stored in a special file with XML format which is especially prepared, facilitating handling and interoperability among applications. The intention of developing the SAS-P2P system was to offer a complementary service for Giga Natal network users, through which the participants in this network can collaboratively build a shared storage area, with important security features such as availability, confidentiality, authenticity and fault tolerance. Besides the specification, development of prototypes and testing of the SAS-P2P system, tests of the PKIX-P2P Manager module were also performed, in order to determine its fault tolerance and the effective calculation of the reputation of the certifying authorities participating in the system
