Brazilian results on structural masonry concrete blocks

The purpose of this paper is to study the mechanical behavior of concrete blocks and prisms when performing axial compression tests within the Brazilian base of knowledge, intending to foment data of this kind for a world-based network. The blocks were built using five different mixtures in which the quantity of cement and the compacting ratio (density) were varied (during the fabrication process). The three-course-high prisms were assembled using 1 cm (0.39 in.) thick full-bedded joints, always trying to leave the mortar's characteristics constant. The axial compression tests were conducted according to Brazilian practice code recommendations, because most of these standards are very similar to international practice codes. The compressive strength, strains, and rupture form of each mixture studied were recorded. Attempts were made to correlate the strength, efficiency ratio (block strength/prism strength) of the prisms, strains, and rupture form; with the quantity of cement and compacting ratio. The data are presented in tables and figures, and the obtained results are discussed throughout the text. Copyright © 2007, American Concrete Institute. All rights reserved.

Shear force and torsion in reinforced concrete beam elements: theoretical analysis based on Brazilian Standard Code ABNT NBR 6118:2007

Reinforced concrete beam elements are submitted to applicable loads along their life cycle that cause shear and torsion. These elements may be subject to only shear, pure torsion or both, torsion and shear combined. The Brazilian Standard Code ABNT NBR 6118:2007 [1] fixes conditions to calculate the transverse reinforcement area in beam reinforced concrete elements, using two design models, based on the strut and tie analogy model, first studied by Mörsch [2]. The strut angle θ (theta) can be considered constant and equal to 45º (Model I), or varying between 30º and 45º (Model II). In the case of transversal ties (stirrups), the variation of angle α (alpha) is between 45º and 90º. When the equilibrium torsion is required, a resistant model based on space truss with hollow section is considered. The space truss admits an inclination angle θ between 30º and 45º, in accordance with beam elements subjected to shear. This paper presents a theoretical study of models I and II for combined shear and torsion, in which ranges the geometry and intensity of action in reinforced concrete beams, aimed to verify the consumption of transverse reinforcement in accordance with the calculation model adopted As the strut angle on model II ranges from 30º to 45º, transverse reinforcement area (Asw) decreases, and total reinforcement area, which includes longitudinal torsion reinforcement (Asℓ), increases. It appears that, when considering model II with strut angle above 40º, under shear only, transverse reinforcement area increases 22% compared to values obtained using model I.

A imprescritibilidade da negatória de paternidade e o melhor interesse da criança

Estudo sobre a filiação com ênfase na regra do caput do artigo 1.601 do Código Civil Brasileiro Lei 10.406/2002, segundo a qual cabe ao marido o direito de contestar a paternidade dos filhos nascidos de sua mulher, sendo tal ação imprescritível. A dissertação tem como objetivo principal demonstrar a inconstitucionalidade do direito perpétuo do pai em desconstituir a paternidade do filho menor nascido em uma relação de casamento à luz do princípio do melhor interesse da criança. Para tanto foi realizada pesquisa bibliográfica e jurisprudencial em tribunais nacionais de segunda instância, no Superior Tribunal de Justiça e no Supremo Tribunal Federal. Os critérios da presunção legal pater is est quem nuptiae demonstrant, da verdade biológica e da posse de estado de filho foram um a um analisados, não havendo entre eles predominância no ordenamento jurídico. O levantamento deste material permitiu a constatação de que a regra supracitada é, pela doutrina majoritária, acriticamente louvada e utilizada nos julgados de conflitos de paternidade. O filho, no entanto, não pode permanecer por toda a vida sujeito à possibilidade do pai desfazer, a qualquer momento, a relação paterno-filial pela ausência do dado biológico por que: (i) o exercício deste direito é mutilador de sua identidade e dignidade humana; (ii) a posse de estado de filho confirma a presunção pater is est; (iii) o estado civil de filho deve se tornar certo e estável em um curto período de tempo. Sustenta-se que é imperioso o afastamento por inconstitucionalidade material da regra do artigo 1.601 do Código Civil e a aplicação analógica do prazo de quatro anos previsto no artigo 1.614 do Código Civil. De lege ferenda propõe-se a elaboração de uma norma que fixe um prazo decadencial para que o marido e pai possa exercer o direito potestativo de negar a paternidade.

A caracterização do trabalho análogo ao escravo na jurisprudência dos tribunais brasileiros

Based on bibliographical research and the analysis of court rulings, this study investigates the characterization of slave-like labor by Brazilian courts. After the alteration of article 149 of the Brazilian Penal Code, introduced by Law nº 10.803/2003, which typifies the practice of contemporary slavery in Brazil, divergent characterizations of this practice remain. The courts currently employ the broadest concept of contemporary slave labor, in which the crime is characterized by the engagement in one of the following conducts established as a criminal offense: labor with the restriction of freedom, submission to exhaustive working conditions, degrading working conditions, and debt bondage. The engagement in one of the above is therefore enough to constitute a crime. Contemporary slave labor in Brazil is not characterized only by the restriction of the worker’s freedom, as in the case of forced labor or debt bondage, but also through the submission of the workers to situations that offend their human dignity. Individual freedom and the dignity of the human person, fundamental tenets of the Brazilian Federal Constitution, are juridical resources safeguarded by law. Contemporary slavery is not limited to the mere infringement of labor laws, but represents a severe violation of the human rights of the workers involved.

Verbal ability, previous practice and load on short-term memory as determiners of differences in a complex learning task: an experimental study

Traditional psychometric theory and practice classify people according to broad ability dimensions but do not examine how these mental processes occur. Hunt and Lansman (1975) proposed a 'distributed memory' model of cognitive processes with emphasis on how to describe individual differences based on the assumption that each individual possesses the same components. It is in the quality of these components ~hat individual differences arise. Carroll (1974) expands Hunt's model to include a production system (after Newell and Simon, 1973) and a response system. He developed a framework of factor analytic (FA) factors for : the purpose of describing how individual differences may arise from them. This scheme is to be used in the analysis of psychometric tes ts . Recent advances in the field of information processing are examined and include. 1) Hunt's development of differences between subjects designated as high or low verbal , 2) Miller's pursuit of the magic number seven, plus or minus two, 3) Ferguson's examination of transfer and abilities and, 4) Brown's discoveries concerning strategy teaching and retardates . In order to examine possible sources of individual differences arising from cognitive tasks, traditional psychometric tests were searched for a suitable perceptual task which could be varied slightly and administered to gauge learning effects produced by controlling independent variables. It also had to be suitable for analysis using Carroll's f ramework . The Coding Task (a symbol substitution test) found i n the Performance Scale of the WISe was chosen. Two experiments were devised to test the following hypotheses. 1) High verbals should be able to complete significantly more items on the Symbol Substitution Task than low verbals (Hunt, Lansman, 1975). 2) Having previous practice on a task, where strategies involved in the task may be identified, increases the amount of output on a similar task (Carroll, 1974). J) There should be a sUbstantial decrease in the amount of output as the load on STM is increased (Miller, 1956) . 4) Repeated measures should produce an increase in output over trials and where individual differences in previously acquired abilities are involved, these should differentiate individuals over trials (Ferguson, 1956). S) Teaching slow learners a rehearsal strategy would improve their learning such that their learning would resemble that of normals on the ,:same task. (Brown, 1974). In the first experiment 60 subjects were d.ivided·into high and low verbal, further divided randomly into a practice group and nonpractice group. Five subjects in each group were assigned randomly to work on a five, seven and nine digit code throughout the experiment. The practice group was given three trials of two minutes each on the practice code (designed to eliminate transfer effects due to symbol similarity) and then three trials of two minutes each on the actual SST task . The nonpractice group was given three trials of two minutes each on the same actual SST task . Results were analyzed using a four-way analysis of variance . In the second experiment 18 slow learners were divided randomly into two groups. one group receiving a planned strategy practioe, the other receiving random practice. Both groups worked on the actual code to be used later in the actual task. Within each group subjects were randomly assigned to work on a five, seven or nine digit code throughout. Both practice and actual tests consisted on three trials of two minutes each. Results were analyzed using a three-way analysis of variance . It was found in t he first experiment that 1) high or low verbal ability by itself did not produce significantly different results. However, when in interaction with the other independent variables, a difference in performance was noted . 2) The previous practice variable was significant over all segments of the experiment. Those who received previo.us practice were able to score significantly higher than those without it. J) Increasing the size of the load on STM severely restricts performance. 4) The effect of repeated trials proved to be beneficial. Generally, gains were made on each successive trial within each group. S) In the second experiment, slow learners who were allowed to practice randomly performed better on the actual task than subjeots who were taught the code by means of a planned strategy. Upon analysis using the Carroll scheme, individual differences were noted in the ability to develop strategies of storing, searching and retrieving items from STM, and in adopting necessary rehearsals for retention in STM. While these strategies may benef it some it was found that for others they may be harmful . Temporal aspects and perceptual speed were also found to be sources of variance within individuals . Generally it was found that the largest single factor i nfluencing learning on this task was the repeated measures . What e~ables gains to be made, varies with individuals . There are environmental factors, specific abilities, strategy development, previous learning, amount of load on STM , perceptual and temporal parameters which influence learning and these have serious implications for educational programs .

Letramento no trânsito: eventos e práticas na formação de condutores de veículos

In the contemporary society, the language is presented in all social spaces and assumes many different purposes in order to meet the needs that emerge from each of these sphere. In traffic, this reality is not different. To guide vehicles, it is necessary to know, by means of reading artifacts, what the legislation establishes in what concerns the way to act in this domain. Thus, this works aims at describing the practices of literacy held in events of driver trainings and know the expectations generated by drivers/learners from this training. In theoretical terms, it anchors in Literacy Studies, comprehended here as social practices (BARTON; HAMILTON, 1998; KLEIMAN, 1995, 2008; MORTATTI, 2004; STREET, 1984; OLIVEIRA, 2008, 2010; ROJO, 2009; PAZ, 2008). Genre Theory (BRONCKART, 2004, 1999; OLIVEIRA, 2010) and in your multimodal instance (KRESS; VAN LEEUWEN, 1996; DIONÍSIO, 2006). In terms of methodology, it follows the bias of qualitative research, because of its ethnographic nature (BOGDAN; BIKLEN, 1994; MINAYO, 2010; CANÇADO, 1994; CHIZZOTTI, 2005). The research corpus was generated by reading the Brazilian Traffic Code, by observing the literacy events held in Drivers Training Centers of Natal, analysis of course books used in these events, plus questionnaires with open and closed questions and semistructured interviews. The collaborators are constituted of drivers in training, and instructors who work in this field. The analyses show significant contributions regarding the placement more committed of future drivers with the welfare and safety of those who use the public roads, from the practice or reading done during the traffic training. The contribution of this work lies in the possibility to expand the discussion about the language practice uses regarding the training for the traffic, more specifically, the training of drivers of vehicles

Pacta sunt servanda versus the social role of contracts: the case of Brazilian agriculture contracts

This study explores the instability created by contradictory court decisions related with contract breaches. Forward marketing contracts represent an important source of resources to finance Brazilian agriculture, however a large number of contract breaches were observed during a period of marked increase in soy prices. The study analyzed 161 judicial appeal decisions and a survey was carried with 70 farmers. The results show the difference of judges' interpretation and the existence of second order effects. The effects of court decisions were more requirements of guarantees and the reduction in the number of contracts. Those soybean farmers who did not breach their contracts have also been negatively affected by the strategic reactions of trading and processing companies. The concept of "social function of the contract" introduced in Brazilian civil code led to a higher degree of instability in contracts, raising transaction costs and motivating private economic sanctions.

Influência do uso e ocupação do solo na qualidade da água e no processo erosivo da bacia de captação do Rio Barro Preto, Coronel Vivida-PR

This study was developed in objecting to investigate the use and occupation of land in 1999, 2005, 2011 e 2015 and estimate soil degradation by laminar erosion and the relation with water quality in 2015 in the catchment basin of the Barro Preto river, Coronel Vivida – PR. For multitemporal analysis of use and occupation of land in the basin used in the Landsat 5, 7 and 8 images and Geographic Information System. The laminar erosion was estimated by the Universal Soil Loss Equation through the systematization of calculations of the factors that compose the equation in SPRING/INPE. The water quality of the studied river section was evaluated according to the Water Quality Idex and the Resolution CONAMA n. 357/2005. The multitemporal analysis of the use and occupation of land has demonstrated that basin is predominantly agricultural in all years studied, as well as the permanent preservation area presents it not regularized during the period in accordance with the Brazilian Forest Code in force. In relation the quantification of laminar soil erosion in the study period, the rainfall and runoff factor was estimated considering the rainfall data from 1986 to 2014 and resulted in a value of 11.573,47 MJ/ha.mm/a. The Dystrophic Red Latosol, Dystrophic Red Nitisol, Fluvisol and Leptosol soil erodibility factor were 0,0138, 0,0137, 0,0207, 0,0196 t.ha.h/ha.MJ.mm/a, respectively. The topographical factor has demonstrated that the catchment basin has the rough terrain because the moderate and moderate strong classes are dominant in the study area. The cover and management and support practice factors were estimated according to the multitemporal analysis of the use and occupation of land in the basin and the values ranged from 0,0006 to 0,0688. The soil losses by laminar erosion were simulated with agriculture areas with corn and soybeans in no-till. The soil losses with maize crop in no-till in 1999, 2005, 2011 and 2015 were 9.782,75, 10.592,71, 9.636,61 e 11.058,26 t/year, respectively, and soybeans crops in no-till were 15.140,01, 16.645,20, 14.662,14 e 17.049,85 t/year, respectively. In relation with water quality of the section studied river, the average of Water Quality Index during the season were 55,47, 53,09 and 49,72, for the first, second and third sample point, respectively. Indication a decrease in water quality since the source to the last sample point. It is concluded that the use and occupation of land in the catchment basin interferes in the water quality, as well as in soil degradation.

The last taboo: Patenting human beings

This article considers the efforts of the Australian Law Reform Commission to clarify the meaning of section 18(2) of the Australian Patents Act 1990 (Cth): ’Human beings and the biological processes for their generation are not patentable inventions.' It provides a critique of the proposals of the Commission with respect to patent law and stem cell research. The Commission has recommended that IP Australia should develop examination guidelines to explain how the criteria for patentability apply to inventions involving stem cell technologies. It has advised the Australian Government that the practice code of the United Kingdom Patent Office (UKPO) would be a good model for such guidelines, with its distinction between totipotent and pluripotent stem cells. Arguably, though, there is a need to codify this proposal in a legislative directive, and not merely in examination guidelines. The Commission has been reluctant to take account of the ethical considerations with respect to patent law and stem cell research. There could be greater scope for such considerations, by the use of expert advisory boards, opposition proceedings and the requirement of informed consent. The Commission has put forward a number of general and specific recommendations to enhance access to patented stem cell technologies. It recommends the development of a research exemption, and the modernisation of compulsory licensing and crown use provisions. It also explores the establishment of a stem cell bank and the promulgation of guidelines by funding agencies. Such proposals to promote greater public access to stem cell research are to be welcomed.

A obrigação de extraditar para a repressão do terrorismo: a prática brasileira à luz do direito penal transnacional

O combate efetivo ao flagelo secular do terrorismo, ainda que possa se revestir de muitas formas, não prescinde da repressão penal de seus autores. Em vista da maciça internacionalização do terrorismo, a partir do Século XX, a cooperação jurídica internacional em matéria penal (aí incluída a extradição) consolida-se como instrumento de essencial importância para a repressão do terrorismo pela comunidade internacional, com a vantagem de resguardar o domínio do direito e, por conseguinte, de assegurar a paz e a segurança internacionais. A evolução do tratamento do crime de terrorismo pelo direito penal transnacional influenciada pelo direito da segurança coletiva, especialmente a partir dos atentados de 11 de setembro de 2001 exerceu expressivo impacto no direito extradicional. O entendimento desse efeito é fundamental para extrair-se do instituto da extradição todo o seu potencial para a repressão penal do terrorismo. Desde que presentes determinados requisitos, uma conduta de caráter terrorista à luz de parâmetros internacionais gera a obrigação estatal de extraditar ou processar seu autor, mesmo na ausência de tratado. Além disso, a extradição exercida ou não em decorrência de obrigação convencional tem seus princípios afetados pela obrigação internacional de repressão do terrorismo, particularmente no que se refere a questões como extraditabilidade, extradição por crimes políticos e extradição de refugiados. O direito brasileiro apresenta algumas vulnerabilidades para o cumprimento da obrigação aut dedere aut iudicare e a prática judicial brasileira relativa à extradição de acusados de atos de terrorismo poderia reportar-se mais ao direito internacional, com vistas a evitar o risco de violação de obrigações internacionais pelo Brasil.
