Três momentos da história da acentuação portuguesa

This article examines the lexical stress positioning in three moments of Portuguese diachrony: in its Latin origin, in medieval times (the so called Archaic Portuguese, of GalicianPortuguese), and in contemporary times, comparing Brazilian and European Portuguese. Two analysis are presented: the first one, based on non-linear Phonology theories, and the second one, based on Optimality Theory. The article shows that the rhythmic chance that affected Portuguese in its diachronic trajectory from Latin to contemporary days is not based in lexical stress positioning, which is still very close to what happened in the original Latin phase of the language.

Gramaticalização e tradição discursiva: um estudo dos processos constitutivos do texto relacionados a assim

This paper is focused in a qualitative analysis on the item assim in correlation to its topic function in Tradições Discursivas (Discursive Traditions), investigated in the from 18th to 21th centuries. The results point out to a close relation between the investigated texts traditions and the changes that have occured concerning the item mentioned above, from a historical conception of non-linear diachrony.

Analysis of metabolic pools in broilers chicks

This paper shows the possibility of obtaining new parameters for the mathematical modelling of data on stable isotopes in biological systems and its application in obtaining data on metabolic pools of blood plasma, blood serum, liver and muscle of broilers. This theory states that the modelling of turnover used for studies of isotopic incorporation when the metabolism has a single metabolic pool is feasible by the technique of setting an exponential. However, when the metabolism has more than one metabolic pool, it is necessary to apply the linearization technique, linear regression adjustment and evaluation of the assumptions of regression to obtain the kinetic parameters such as half-life (T1/2) and isotope exchange rate (k). The application of this technique on carbon-13 data from 100 one-day-old chicks, with the change of diet composed of grains of the photosynthetic cycle of plants from C4 to C3, in broilers has enabled the discovery that the liver, blood plasma and blood serum have a single metabolic pool; however, the pectoral muscle has two metabolic pools. For the liver, blood plasma and blood serum, the half-life values were found by the exponential fit being T1/2 = 1.4 days with the rate of exchange of k = 0.502, T1/2 = 2.4 days with k = 0.293 and T1/2 = 2.0 days with k = 0.348, respectively. For the pectoral muscle, after linearization, the half-life values were found for T1/2(1) = 1.7 and T1/2(2) = 3 days, with exchange rates of k1 = 0.405 and k2 = 0.235, representing approximately 66 and 34 %, respectively.

Assistência em saúde: revisão integrativa do conhecimento produzido à luz da complexidade

This is part of an integrative review whose object of study was the production of knowledge in journals concerning nursing studies that have used the Theory of complexity as a theoretical framework. This study gathers seven articles collected from a literature review of 18 publications found on the databases: Medical Literature Analysis and Retrieval Sistem on-line (MEDLINE), Literatura Latino-Americana e do Caribe emCiências da Saúde (LILACS) and Cumulative Index to Nursing and Allied Health Literature (CINAHL) from 1998 to 2008. In the two former databases, the following combination of key words was used: “complexity theory” and “health” and “nursing”, and in the third: “complexidade” and “saúde” and “enfermagem. Content analysis was the methodological framework that allowed for organizing the knowledge aggregated in the theme: Health Care. It was observed that the Complexity Theory has based the comprehension of the health care process, pointing out the care provider with his practices and the environment.

The effect of flex fuel vehicles in the Brazilian light road transportation

The retaking of the ethanol program in the year 2003 as a fuel for light road transportation in Brazil through the introduction of flex fuel vehicles fleet was a good strategy to overcome the difficulties of the ethanol production sector and did work to increase its market share relative to gasoline. This process, however, may cause a future disequilibrium on the food production and on the refining oil derivates structure. In order to analyze the substitution process resultant of the competition between two opponents fighting for the same market, in this case the gasoline/ethanol substitution process, a method derived from the biomathematics based on the non-linear differential equations (NLDE) system is utilized. A brief description of the method is presented. Numerical adherence of the method to explain several substitution phenomena that occurred in the past is presented in the previous author`s paper, in which the urban gas pipeline system substitution of bottled LPG in the dwelling sector and the substitution of the urban diesel transportation fleet by compressed natural gas (CNG) buses is presented. The proposed method is particularly suitable for prospective analysis and scenarios assessment. (c) 2008 Elsevier Ltd. All rights reserved.
