Abstract: context and objective: studies using radionuclides are the most appropriate method for estimating renal function. dimercaptosuccinic acid chelate labeled with technetium-99m (99mtc-dmsa) is the radiopharmaceutical of choice for high-resolution imaging of the renal cortex and estimation of the functional renal mass. the aim of this study was to evaluate a simplified method for determining the absolute renal uptake (aru) of 99mtc-dmsa prior to nephrectomy, using the radioactivity counts of nephrectomy specimens as the gold standard. design and setting: prospective study at the division of nuclear medicine, department of radiology, universidade estadual de campinas. methods: seventeen patients (12 females; range 22-82 years old; mean age 50.8 years old) underwent nephrectomy for various reasons. renal scintigraphy was performed three to four hours after intravenous administration of a mean dose of 188.7 mbq (5.1 mci) of 99mtc-dmsa, which was done six to 24 hours before surgery. the in vivo renal uptake of 99mtc-dmsa was determined using the radioactivity of the syringe before the injection (measured using a dose calibrator) and the images of the syringe and kidneys, obtained from a scintillation camera. after surgery, the reference value for renal uptake of 99mtc-dmsa was determined by measuring the radioactivity of the nephrectomy specimen using the same dose calibrator. results: the aru measurements were very similar to those obtained using the reference method, as determined by linear regression (r-squared = 0.96). conclusion: aru estimation using the proposed method before nephrectomy seems to be accurate and feasible for routine use.

Abstract: in brazil, the analysis of statistics shows that crime and criminality data are produced and that they are part of our criminal justice system history. nevertheless, these data are not transformed into information and knowlegde, even after the re-democratization of the country. the raising amount of produced data, which results from the technological modernization of the state, causes the opacity of excessive exposure and allows the circulation of transparency discourses without the occurence of actual changes in governmental rules and practices. to sum up, the re-definition of those statistics role does not rely on technical aspects, which are controlable and depend on decision making; it relies on political aspects that can attribute responsibilities and resolve conflicts.

Abstract: this article assesses the influence of race and gender in the functioning of the s?o paulo state criminal justice system. through the use of longitudinal analysis, that is, analysis that tracks individuals as they make their way through the criminal justice system (in this case, from indictment to the serving of the sentence for robbery), one may observe the different treatments accorded to women and men, blacks and whites.

Abstract: the objective of this research was to evaluate the npk fertilizer effect on 'valencia' sweet orange nursery tree (citrus sinensis) development, budded on rangpur lime rootstocks (c. limonia) in a protected environment using containers with pinus bark, vermiculite and perlite substrates. the experiment consisted of a complete (1/5) 53 factorial randomized block design. treatments comprised five concentrations in g per plant of n: 1.25; 6.25; 11.25; 16.25; 21.25; five concnetrations of k: 0.42; 3.75; 6.22; 9.34; 12.45; and five concentration of p: 0.19; 0.89; 1.59; 2.29; 2.99. nitrogen and k were applieded weekly, and 37.5% of the total fertilization was applied to rootstocks. all p was supplied at planting. leaf, root, stem, shoot and total dry matter production, shoot/root ratio, leaf area, plant height, root system volume; leaf area dry matter ratio stem diameter were evaluated. response functions were adjusted and nutrient rates for maximum yield are presented. results showed that fertilizer level that lead to the best 'valencia' sweet orange on rangpur lime nursery tree response was (g per plant): n, 9.85; p, 2.86; k, 7.99.

Abstract: 'valencia' sweet orange nursery trees (citrus sinensis) budded on rangpur lime rootstocks (c. limonia) were grown in containers using pine bark, vermiculite and perlite as substracts with the objective of evaluating the npk fertilization effect on macronutrient levels. the experiment was a complete (1/5) 53 factorial randomized block design. treatments comprised five concentrations in g per plant of n: 1.25; 6.25; 11.25; 16.25; 21.25; five concnetrations of k: 0.42; 3.75; 6.22; 9.34; 12.45; and five concentration of p: 0.19; 0.89; 1.59; 2.29; 2.99. nitrogen and k were applieded weekly, and 37.5% of the total fertilization was applied to rootstocks. all p was supplied at planting. young and old leaves, root and stem total nutrient concentrations of n, p, k, ca, mg, s and npk accumulation were evaluated. tissue n concentration was directly and p and k concentrations were inversely related to nitrogen fertilization. calcium, mg and s concentrations increased up to the intermediate n fertilization rates. k fertilizer inhibited ca and mg absorption by plants. rootstock npk accumulated as 30% in roots and 70% in shoot.

Abstract: Mudas de laranjeira 'Valência' (Citrus sinensis) sobre o porta-enxerto de limoeiro 'Cravo' (C. limonia) foram cultivadas em vasos com substrato de casca de Pinus, vermiculita e perlita com o objetivo de avaliar-se os efeitos do fornecimento de N, P e K sobre os teores de macronutrientes do porta-enxerto e das mudas. Utilizou-se um esquema de fatorial fracionário (1/5)53 com um delineamento em blocos ao acaso. Os tratamentos consistiram em 5 doses (em g por planta) de N: 1,25; 6,25; 11,25; 16,25; 21,25; 5 doses de K: 0,42; 3,75; 6,22; 9,34; 12,45; e 5 doses de P: 0,19; 0,89; 1,59; 2,29; 2,99. O N e K foram fornecidos semanalmente, sendo 37,5% da dose para o porta-enxerto. O P foi fornecido totalmente no plantio. Determinaram-se os teores totais de N, P e K, Ca, Mg e S nas folhas novas e velhas, raízes e caule e a extra o de N, P e K. Os teores de N relacionaram-se diretamente e os de P e K inversamente com a aduba o nitrogenada. Os teores de Ca, Mg e S relacionaram-se positivamente até as doses intermediárias de N utilizadas. Houve efeito inibitório do fertilizante potássico sobre a absor o de Ca e Mg. A acumula o de NPK pelos porta-enxertos foi em torno de 30% pelas raízes e 70% pela parte aérea.

Da ética do dever-ser a ética do diálogo
Wellington Lima Amorim,Sérgio Ricardo Gacki
Poiésis , 2011,
Abstract: This paper intend to demonstrate the apparent contradiction of Hegelian thought. Hegel's attempt isto unite with the substance of Spinoza and whit the “I free” of Kant, in other words, necessity andcontingency. As we know this project is unfinished, and a modal operator, ie, a “must be” cosmicbeing weaker than the “must be” Kantian permeating the whole system, does not resolve thisquestion.To reflect about this problematic leads us to the concept of ethical dialogue in Gadamerand you can take us toward an intersubjective ethical structure. Therefore, one must postulate suchquestion “ab initio’ to justify the way of this argument, recognizing that this dimension of the humanmeeting, advocates the dialogue as a hermeneutical core of this ethical structure. In Gadamer thereis an invitation to a recognition of what is at stake: the dialogue. On the horizon of hermeneuticperspective, the dialogue is in a praxis, a fundamentally ethical stance.
