Programa Liberdade assistida em Natal/RN: adolescentes em conflito com a lei e a violação de direitos

This work shows the results of the research: Attended Liberty Program Adolescents in Conflict with the Law and the Disapproval of Rights, effected in the community of Natal, Rio Grande do Norte, in period of august 2007 to September 2008. It aims to analyze the social-educative attendance directed to adolescents in conflict with the law through the state, since the Social-educative Measure Attended Liberty, known, as an idoneous way of confrontation to the practice of infraction acts imputed to the adolescent, that needs to give emphasis, in disadvantage of the Social-educative Measurement of Internment, to be proposed (ECA, art 118 and 199) to follow the adolescent in this quotidian, close to his family and community, proposing him through social-educative work, the access to education and occupancy, as well other public services, that help him to surpass the context of privation and disapproval of rights in which lives joined to his family. In our study, it was observed in sequence of approaching, subsidized for theoretical-methodological procedures justified in quantity and quality research, that were privileged to the documental research, the observation and the interview almost structured, besides a theoretical basis about the subject, that the relation of category and inequality in which the capitalist society sustains itself, does the practice of infraction acts imputed to the adolescent, acquires a classist character, in which the property of the money defines the access of the justice. And more, many of the poor adolescents that get into conflict with the law, dweller of the periphery districts of Natal/RN, becomes evident as for segment that has been attended in the Jurisdiction of the Infancy and Youth and in the LAN of Social-educative Attendance, becoming individual the infraction act and its confrontation. We hope in this work, to contribute for the care of the reality of the adolescent in conflict with the law in the Attended Liberty Program, without pretension to exhaust it, as well as later studies about the theme

Adolescentes em conflito com a lei: a saga das punições na rota da exclusão social

This work deals with the problematic of the determinations that contribute to become the adolescents involved with law. Thus, in this research, the social exclusion is apprehended as one of the most important determining to understand this problematic, once we defend that it is part of the trajectory of this adolescent's life since its birth as a punishment that starts before they becoming envolved in act's that break the law. It is still questioned the discussion of the reduction of the penal age, viewed aa a proposal that will contribute to perpetuate the repression. The objectives of the research were: analyze the problematic of adolescents in conflict with law, where social exclusion is seen here as a main category. The research also aims to understand the situation towards social exclusion and that this public is undertaken in the state of Rio Grande do Norte, more specifically in Natal. This is dane through analysis of the profile of adolescents that are submitted to the treatment at Centro Integrate de Atendimento ao Adolescente Acusado de Ato Infracional - CIAD in 2005. This is dane on arder to identify of the State's and society's actions towards this issue, how it has prevailed in analyzing if there is punishing or social protection. The research also contributed with discussion towards the non penal reduction of for underage minors. The approach realized if of qualiquantitative nature. The research was realized with 190 male adolescent subjects, age ranging from 12 to 21 that were interns at CIAD in the year of 2005. The research shows that their fundamental rights (education, health, amongst others) are disrespected on a daily basis by the State. The State prioritizes economic issues, making social inequality more profound. The main argument is that this problematic has its main oring in the social exclusion and it is imposed to the adolescents as a punishment before thes have been involved with the law going on top of the social protection. When the adolescent goes from being the victim to executioner, the Statute of Children and Adolescents is questioned by many sectors that defend the reduction of penal minority as a solution to reduce the country's violence. Thus, it was aimed here to discuss arguments that point to non exclusion, discrimination and repression. It is proposed that the State should assume children and adolescents as a priority, implementing what the statute establishes as well as assures related to the fruition of denied rights as a way to prevent their future involvement with violence

Effect of fractional urea clearance on survival of hemodialysis patients in relation to gender

Many studies have demonstrated the relationship between dialysis dose and survival. Global mortality is similar among men and women; however, the influence of dialysis dose in the survival could be more intensive between women. Therefore, we conduct an observational study to evaluate the gender-related impact of single pool Kt/V (spKt/V) on the survival of patients submitted to hemodialysis in a university hospital. We found that survival was lower in groups with spKt/V smaller than 1.2 than in those with Kt/V between 1.2 and 1.4. Among female patients, spKt/V smaller than 1.2 had a more adverse effect in survival than among men with a comparable Kt/V. Otherwise, among women, the dialysis dose had an impact in survival even with Kt/V greater than 1.4. Thus, fractional urea clearance more heavily influenced the survival of females than males in hemodialysis patients.

Representações sociais de lei, justiça e injustiça: uma pesquisa com jovens argentinos e brasileiros utilizando a técnica de evocação livre de palavras

Este estudo teve como objetivo analisar as principais representações sociais de lei, justiça e injustiça apresentadas por jovens argentinos e brasileiros. O grupo de brasileiros constituiu-se de 621 pesquisandos, de três regiões distintas: Floriano/PI, Erechim/RS e Marília/SP. da Argentina, participaram 200 jovens da cidade de Avellaneda (região metropolitana de Buenos Aires). Os grupos foram proporcionalmente divididos conforme o tipo de escola (pública e particular) e o ano escolar freqüentado (8º ano do Ensino Fundamental e 3º ano do Ensino Médio, considerando-se os graus equivalentes na Argentina). O instrumento de coleta de dados constituiu-se de um questionário semidirigido, composto pela técnica de evocação livre de palavras. O procedimento utilizado para a avaliação dos resultados foi a Análise de Correspondência (ANACOR). Os resultados demonstraram variações importantes relacionadas à nacionalidade dos jovens e foram discutidos de forma a contextualizarem-se as representações apresentadas.

O império da lei: ensaio sobre o cerimonial de sagração de D. Pedro I (1822)

Ce texte analyse le cérémonial royal de la monarchie constitutionnelle brésilienne: le sacre et le couronnement de l'Empereur D. Pedro I. Notre examen de ce cérémonial a comme point de départ son caractère liturgique, pour comprendre pourquoi cet aspect a été considéré essentiel alors pour affirmer l'autonomie du nouveau royaume et, en même temps, a contribué pour définir le pouvoir politique de l'Empire du Brésil.

The effect of drying and urea treatment on nutritional and anti-nutritional components of browses collected during wet and dry seasons

Fibre, crude protein and tannin concentrations were measured in browse species from the semi-arid region of Northeast Brazil during the dry and wet seasons. The effects of oven-, sun- and shade-drying and of urea treatment were also determined. Crude protein (CP) content varied from 103 to 161 g/kg dry matter (DM) and the browses had similar CP content in the two seasons (during 2002) (102-161 and 107-153 g/kg DM in the wet and dry seasons, respectively). Total tannin concentrations ranged from 13 to 201 g/kg DM amongst the browses and were higher in the dry season. A 30-d treatment with urea reduced extractable tannins significantly (P < 0.05). The urea treatment was also most effective at reducing the in vitro effects of tannins compared to the other drying treatments. This was demonstrated by measuring the effect of polyethylene glycol (PEG) on gas production. Addition of PEG increased gas production of oven- (81.4%), sun- (78.5%) and shade-dried (76.7%) samples much more compared to urea treated samples (10.9%). (c) 2005 Elsevier B.V.

Productive and reproductive performance of heifers fed different levels of urea in the diet

The objective of the present study was to evaluate the nutrient intake, blood parameters, follicular diameter and performance of pre-puberty crossbred heifers fed isoproteic diets (14.1%CP) containing 0.0; 0.44; 0.88 and 1.32% urea on the total dry matter (DM) of the diet, with a 77:23 roughage:concentrate ratio. Twenty-four 18- month old heifers (Holstein x Zebu), 277.9 kg mean live weight (LW) were used, distributed in four treatments and six replications in a randomized complete design. The following were evaluated: dry matter intake (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), ether extract (EE), hemicellulose (HEM), plasmatic ureic nitrogen (PUN), plasmatic glucose, plasmatic total cholesterol, follicular diameter and daily weight gain (DWG). No influence of the urea levels in the diet was observed on NDF and HEM intake. A maximum intake was obtained of DM (8.75 kg day(-1)), CP (0.88 kg day(-1)), ADF (2.5 kg day(-1)) and EE (0.17 kg day(-1)) respectively for the levels 0.7, 0.8, 0.7 and 0.7% urea in total DM. The 0.6%; 0.77% and 0.6% urea levels in diet were the critical points for obtaining maximum response for the PUN (10.96 mg dL(-1)) and plasmatic glucose (84.97 mg dL(-1)) concentrations and, for follicular diameter (11.08 mm) on the 40(th); 24(th) and 31(st) day, respectively. The plasmatic total cholesterol concentration and DWG were not influenced by the urea added to the diet, with averages of 119.39 mg dL(-1) and 1.66 kg day(-1), respectively. It was concluded that urea can be added up to 1.32% on the total DM of the diet for pre-puberty crossbred heifers.

Urea-Based Synthesis of Zinc Oxide Nanostructures at Low Temperature

The preparation of nanometer-sized structures of zinc oxide (ZnO) from zinc acetate and urea as raw materials was performed using conventional water bath heating and a microwave hydrothermal (MH) method in an aqueous solution. The oxide formation is controlled by decomposition of the added urea in the sealed autoclave. The influence of urea and the synthesis method on the final product formation are discussed. Broadband photoluminescence (PL) behavior in visible-range spectra was observed with a maximum peak centered in the green region which was attributed to different defects and the structural changes involved with ZnO crystals which were produced during the nucleation process.

Coordination of Eu3+ ions in siliceous nanohybrids containing short polyether chains and bridging urea cross-links

Infrared and photoluminescence spectroscopies have been used to investigate the local environment of the Eu3+ ions in luminescent sol-gel derived materials-di-ureasils-based on a hybrid framework represented by U(600). This host is composed of a siliceous backbone grafted, through urea cross-links, to both ends of polymer segments incorporating 8.5 oxyethylene repeat units. The active centers have been introduced as europium perchlorate, Eu(ClO4)3. Samples with compositions n = 232, 62, 23, 12, and 6 (where n denotes the ratio of (OCH2CH2) moieties per lanthanide ion) have been examined. The combination of the information retrieved from the analysis of characteristic bands of the FTIR spectra-the perchlorate and the Amide I/Amide II features-with that obtained from the photoluminescence data demonstrates that at compositions n = 232 and 62 the anions are free, whereas the Eu3+ ions are complexed by the heteroatoms of the polyether chains. At higher salt concentration, the cations are bonded, not only to the ClO4 - ions, but also to the ether oxygen atoms of the organic segments and to the carbonyl oxygen atoms of the urea linkages. The dual behavior of U(600) with respect to cation coordination has been attributed to the presence in this nanohybrid of strong hydrogen-bonded urea-urea structures, which, at low salt content, cannot be disrupted, thus inhibiting the formation of Eu3+-O=C(urea) contacts and promoting the interaction between the lanthanide ions and the (OCH2CH2) moieties. The present work substantiates the claim that the activation of the coordinating sites of the di-ureasil framework can be tuned by varying either the guest salt concentration at constant chain length or the length of the.organic segments at constant salt concentration. This relevant property opens challenging new prospects in the fields of application of this class of hybrids. © 2001 American Chemical Society.
