The construction industry is one of the largest consumers of natural raw materials, and concrete is considered today the most used material wide. This accentuated consumption of natural resources has generated concern with the preservation of the environment, and has motivated various studies related to the use of resid ues, which can partially or entirely substitute, with satisfactory performance, some materials such as the aggregate, and in so doing, decrease the impact on the environment caused by the produced residues. Research has been done to better understand and improve the microstructure of concrete, as well as to understand the mechanism of corrosion in reinforced steel. In this context, this work was developed aiming at discovering the influence of the substitution of natural sand by artificial sand, with rega rd to mechanical resistance, microstructure, and durability. To obtain the electrochemical parameters, an adaptation was made to the galvanostatic electrochemical method to study the corrosion in reinforced steel. Concretes of categories 20 MPa and 40 MPa were produced, containing natural sand, and concretes of the same categories were produced with artificial sand substituting the natural sand, and with the addition of sodium nitrate and sodium chloride. Due to the use of rock dust reject (artificial sand), an evaluation was made of its environmental risk. The results indicate that the concretes of category 20 MPa present a better performance than the concrete made with natural sand, thus making it a viable substitute. For the category 40 MPa, the better performance is from the concrete containing natural sand. The adaptation of the galvanostatic electrochemical technique to the study of the corrosion of reinforced steel within concrete proved to be valid for obtaining electrochemical parameters with a high degree of reliability, considering the number of degrees of freedom

Female hawksbill turtles (Eretmochelys imbricata) nesting along the southeastcoastline of Rio Grande do Norte State, Brazil (6º13'40"S, 35º03'05"W) were captured and weighed during the four months from January to April 2007, in the course of the annual egglaying season, which extended from 06 rd November 2006 to 30 rd May 2007. In all, 99 weight measurements were performed. On first contact the females exhibited an average post-oviposition weight of 79.1 kg (range 56.2-98.9 kg, SD = 10.9 kg, n = 44 females). Those individuals which were subsequently recaptured showed a mean weight loss of 1.7 kg (range 0.7-4.5 kg, SD = 1.0 kg, n = 39 sets of measurements on 20 females) in the interval between two consecutive post-ovipositions, separated by a maximum time interval of 17 days. In the cases where the female aborted the nesting process, the pre-oviposition weight was measured. The clutch weight, that is to say, the weight loss between consecutive pre-oviposition and post-oviposition measurements (separated by a maximum time interval of 3 days), was found to be 5.2 kg (range 4.3-6.0 kg, SD = 0.9 kg, n = 6 sets of measurements). This value is significantly higher (t-test, p<0.001) than the loss between two consecutive post-oviposition measurements with the same female. The mean recovery in body weight, that is to say, the average gain in weight between successive post-oviposition and pre-oviposition captures of the same individual (separated by a time interval of 12 to 17 days), was found to be 3.0 kg (range 1.9-4.3 kg, SD = 1.0 kg, n = 4 sets of measurements) Although the small sample size makes it unwise to generalise, the recovery in body weight was found to be always significantly lower (t-test, p<0.005) than the clutch weight. This fact is in agreement with the observed weight loss tendency throughout the breeding season for this species. Considering the clutch weight and the internidal recovery in body weight we found that the total weight loss of the adult hawksbill females after three to five nesting events varied from 10.4% (range 8.7-11.9%, SD = 1.6%, n = 3) to 14.1% (range 11.8-15.4%, SD = 1.3%, n = 6) in relation to their initial pre-oviposition weight. If there were no body weight recovery during the internesting interval we estimate that a female that nests three to five times in the course of the season would lose from 19% to 31% of its initial weight. We emphasise that our clutch weight estimate was performed by weighing the females and not by multiplying the number of eggs in the nest by their average unit weight. In this way, our measurements take into account the loss of liquid during the oviposition. Despite the unequivocal evidence of body weight recovery during the internidal interval, it is not clear if the cause of this process is rehydration or feeding

The present study had as a main objective to analyze how the professionals at a CAPS ad unit in Natal-RN conceive the knowledge-practice process with regard to the Harm Reduction Policy (HRP) towards alcohol and other drugs. For the accomplishment of this proposal, it was intended: 1) Verifying the possibilities and limits of the HRP implementation at a CAPS ad unit in Natal-RN; 2) Relating the professionals knowledge at a CAPS ad unit in Natal in regard to the Harm Reduction Policy; 3) Enumerating the HRP programmatic actions at the institution. The research had exploratory, descriptive and qualitative approach aspects, guided by the concepts of biopower and self care proposed by Michel Foucault. Data collection occurred in June and July 2011, in which the focal group technique was used. After that, collect field material was analyzed through the content analysis method proposed by Minayo. The results showed some conceptual and practical approach between the harm reduction strategy and the knowledge-practice of the professionals at this CAPS ad unit. The discursive models about drug usage, especially the moral-legal model, still have a significant role in the daily lives of these professionals, being amplified by some demands of their jobs or even through the instituted discourse. The individuals recognize the need for less prohibited practices and more socializing ones, identifying them with the Harm Reduction (HR) logic, when there is a coherent and well-founded understanding about HR among the professionals. Distorted and reductionist views about HR as considering the simple instrumental function of this strategy (distribution of basic supplies) among the professionals, represent one of the main barriers for its implementation. There are few programmatic activities that are related to the RD strategy at this CAPS ad unit which makes a more effective appropriation by the working team difficult to reach. The working processes and the postures adopted by this CAP ad unit professionals have been showing that many of their practices and conceptions were modified to the detriment of new necessities emerged from the demands. Consequently, the self care notion is revealed which brings the need for the valorization of these care agents roles, that is, their collective and individual contribution.

Knowledge and innovation were seen as major forces, both for survival, as the acquisition of competitive advantages in the Brazilian economy, as well as adding value to the product as a market differentiator. The Triple Helix model is directed toward the knowledge-based economy. Over the past six years, the Federal Government through the Financier of Studies and Projects ( FINEP ) invested in technological innovation projects, economic subsidies, about U.S. $ 1 billion supporting more than 800 projects with these resources. According to the MCTI , the Northeast, over the years 2000 to 2010 increased spending on Science and Technology (considering the activities of research and development more scientific and related activities) of the State Government in relation to its total revenue In 2000, 0.51% of total revenues were invested in Science & Technology, while in 2010 this figure increased to 1.31%. Among the nine Northeast states, Paraíba is highlighted. In 2000, 0.33% of its total revenues were directed to innovation, reaching 2.04% in 2010, the largest increase in the region while the RN invested 0.24% in 2000 and in 2010 reached the level of 1.42 %. According to IBGE, in the period 2000-2011, the micro and small enterprises surpassed the barrier of 6 million establishments. In 2000, there were 4.2 million establishments while in 2011 were 6.3 million active establishments. Therefore, throughout the period, there was a creation of approximately 2.1 million new establishments. Between 2000 and 2011, micro and small businesses have created 7.0 million formal jobs, 8.6 million jobs in 2000 to 15.6 million in 2011. This scenario shows the importance of this study in relation to the investment of governments in RD & I in micro and small enterprises. This study aims to analyze the interaction Universities - Business - Government in the development of innovation in micro and small companies in Rio Grande do Norte participants of the edicts of Inova FAPERN. We chose to adopt as a research method case study concerning the procedure of the research, exploratory, descriptive, and on documents with engineers and researchers of innovation projects approved by PAPPE Subsidy (Inova -RN I, II and III). Data collection was done through the report made by FAPERN entitled: " Evaluation of companies financed and supported by the Grant Program for Technological Innovation for Micro and Small Enterprises RN - INOVA -RN " (2010) and a questionnaire with 40 closed questions and 1 opened to 30 affirmative composed based on a 5-point Likert scale. The analysis of data was qualitative and quantitative. The study provided to identify the importance and barriers arising from the relation between Government Enterprise (micro and small) and University as essential to the economic development of the region. It was also identified that, in the innovation projects, 70% of the goods or services originating from research were to market these, 50% resulted in a patent for the company and 80% publications of scientific articles

The harm reduction HR is the official policy of Ministry of Public Health to deal with problem derived from alcohol consumption and other drugs AD. The HR refers to policies and support programs whose purpose is to reduce the risks related to the use of AD, without necessarily decrease individual consumption. This research aim was to analyze the HR conceptions and practices at two specialized institutions for AD users: 1) Psychosocial Care Center Alcohol and Drugs III (CAPSad III); 2) Therapeutic Community Fazenda da Esperança (FE) Dom Bosco. This is a qualitative research that used the following methodological tools: semi-structured interview with 21 professionals; socio demographic file and rounds of conversation with 63 participants users; participant observation and field journal. The interviews with professionals have characterized HR as a less complex and cheap treatment. At FE the HR proposal does not make part of their actions, being considered ―against the human being dignity‖. At CAPSad III is understood as an ―inevitable‖ guideline to service, once users do not remain abstinent. The users understand RD as an improvement in healthy conditions, social relations and work that occurs with the decreasing consumption of AD. They use the HR when they avoid situations that facilitate AD consumption, share relapse prevention strategies and, exclusively at CAPSad III, decrease psychotropic consumption. Stands out as an analyzer the HR comprehension as a less efficient treatment that opposes to the objective of both institutions, which is abstinence. The HR is not operationalize in daily routine by professionals and users as a healthy promotion strategy, however, the users are more affected to HR and produce strategies to face the difficulties arising from the AD consumption

In this work we studied the consistency for a class of kernel estimates of f f (.) in the Markov chains with general state space E C Rd case. This study is divided into two parts: In the first one f (.) is a stationary density of the chain, and in the second one f (x) v (dx) is the limit distribution of a geometrically ergodic chain

In this work, we studied the strong consistency for a class of estimates for a transition density of a Markov chain with general state space E ⊂ Rd. The strong ergodicity of the estimates for the density transition is obtained from the strong consistency of the kernel estimates for both the marginal density p(:) of the chain and the joint density q(., .). In this work the Markov chain is supposed to be homogeneous, uniformly ergodic and possessing a stationary density p(.,.)

The problem treated in this dissertation is to establish boundedness for the iterates of an iterative algorithm in 2, under some technical conditions. However, this paper uses non-trivial intuitive arguments and its proofs lack suficient rigor. In this dissertation we discuss and strengthen the results of this paper, in order to complete and simplify its proofs
