Restructuring Passiflora cincinnata fruit pulp: influence of hydrocolloids

This study evaluated the effect of mixtures of alginate, low methoxy pectin and gelatin on characteristics of P. cincinnata fruit gels, containing pulp with high soluble solids content (50 °Brix). The results of a central composite design showed that the models obtained, except for water activity and pH, were predictive. Gelatin was an important factor affecting firmness and colour parameters since higher concentrations of this hydrocolloid, combined with alginate concentrations greater than 1.3% and pectin quantity up to 1.26%, could be used to obtain clear yellow products with firmness greater that 1.2 kg.

Back pain in adults living in quilombola territories of Bahia, Northeastern Brazil

OBJECTIVE To analyze the factors associated with back pain in adults who live in quilombola territories. METHODS A population-based survey was performed on quilombola communities of Vitória da Conquista, state of Bahia, Northeastern Brazil. The sample (n = 750) was established via a raffle of residences. Semi-structured interviews were conducted to investigate sociodemographics and employment characteristics, lifestyle, and health conditions. The outcome was analyzed as a dichotomous variable (Poisson regression). RESULTS The prevalence of back pain was of 39.3%. Age ≥ 30 years and being a smoker were associated with the outcome. The employment status was not related to back pain. CONCLUSIONS The survey identified a high prevalence of back pain in adults. It is suggested to support the restructuring of the local public service in order to outline programs and access to healthy practices, assistance, diagnosis, and treatment of spine problems.

The distribution of tuberculosis in Porto Alegre: analysis of the magnitude and tuberculosis-HIV coinfection

Objective Analyzing the geographical distribution of the tuberculosis (TB), its incidence and prevalence and TB-HIV coinfection in the districts of Porto Alegre from 2007 to 2011. Method An ecological, descriptive study of time series that used descriptive and geoprocessing techniques. Results In total, were recorded 3,369 incident cases and 3,998 prevalent cases of pulmonary TB. In both contexts, there was predominance of cases in males and in Caucasians. Seventeen districts showed prevalence rates above 79.2 cases/100,000 inhabitants, considering that 15 of them had incidence rates above 73.7 cases/100,000 inhabitants. The TB-HIV coinfection rates reached 67% in some districts, which is above the city average value (30%). Conclusion The distribution analysis showed that the reformulation and restructuring of policies and health services in Porto Alegre are essential.


Morphostructural characterization of soil conventionally tilled with mechanized and animal traction with and without cover crop

The structural stability and restructuring ability of a soil are related to the methods of crop management and soil preparation. A recommended strategy to reduce the effects of soil preparation is to use crop rotation and cover crops that help conserve and restore the soil structure. The aim of this study was to evaluate and quantify the homogeneous morphological units in soil under conventional mechanized tillage and animal traction, as well as to assess the effect on the soil structure of intercropping with jack bean (Canavalia ensiformis L.). Profiles were analyzed in April of 2006, in five counties in the Southern-Central region of Paraná State (Brazil), on family farms producing maize (Zea mays L.), sometimes intercropped with jack bean. The current structures in the crop profile were analyzed using Geographic Information Systems (GIS) and subsequently principal component analysis (PCA) to generate statistics. Morphostructural soil analysis showed a predominance of compact units in areas of high-intensity cultivation under mechanized traction. The cover crop did not improve the structure of the soil with low porosity and compact units that hamper the root system growth. In areas exposed to animal traction, a predominance of cracked units was observed, where roots grew around the clods and along the gaps between them.

Raw-appearing Restructured fish models made with Sodium alginate or Microbial transglutaminase and effect of chilled storage

Restructuring by adding Sodium Alginate or Microbial Transglutaminase (MTGase) using cold gelation technology make it possible to obtain many different raw products from minced and/or chopped fish muscle that are suitable for being used as the basis of new restructured products with different physicochemical properties and even different compositions. Special consideration must be given to their shelf-life and the changes that may take place during chilling, both in visual appearance and physicochemical properties. After chilled storage, the restructured models made with different muscular particle size and composition at low temperature (5 °C), it was observed that microbial growth limited the shelf-life to 7-14 days. Mechanical properties increased (p < 0.05) during that time, and higher values were observed in samples elaborated by joining small muscle particle size than in those elaborated by homogenization. There was no clear increase in the cooking yield and purge loss, and no significant colour change (p > 0.05) was detected during storage.

Mudança em tempos de globalização: o capitalismo não é mais progressista?

Technical progress and economic development are promotions of capitalism, says a well known idea hereby contradicted. Recent changes under neoliberalism show that the more freedom of move to capital the less development of productive forces. There was no synchronicity and coherence fostering economic growth between changes at the micro level of techno-productive and managerial innovations and the ones at the macro level of institutional structures and economic policy. Empowerment of finance capital and monopolies got them opportunity to control the state and set its economic policy to support fictitious capital accumulation and to rule restructuring of corporate management. Surplus redistribution favoring finance capital is a burden to be carried on the back of society's productive structures, lowering investment, employment and growth. Focusing Latin America and Brazil, the same picture is seen, worsened by external fragility that deepens historical dependency.

External debt in developing economies: assessment and policy issues

More than one decade after the external debt restructuring (the Brady Plan), a great amount of literature has been published concerning the balance sheet factors in developing countries. The staff of international multilateral institutions joined with reputable academics in this great controversy. The external debt problem of the developing countries is back and once more reflections on its cause and on policy recommendations are analytically distinct. Our main task is to reflect on the recent external debt dynamics and assess how this debt has evolved. Our findings indicate that the susceptibility of some developing countries to default is associated with global imbalance, that is, the way they borrow.

Os pilares institucionais da política cambial e a industrialização nos anos 1930

The Institutional pillars of the foreign exchange policy and industrialization in Brazil in the 1930s. The 1930s constitute one milestone in the Brazilian economic development, as the accelerated industrialization process has started and became the dominant domestic policy. This paper reviews this period focusing on the institutional changes restructuring exchange transactions, to curb financial flows and balance external payments

The boom and crisis of the Convertibility Plan in Argentina

This article analyses the relationship between state policies and economy in Argentina 1991-2001. In 1991 the currency board regime named 'convertibility' was implemented, within the framework of important neoliberal reforms introduced by the State. These neoliberal reforms facilitated capitalist restructuring, characterized by a leap in productivity, investment and profits. Likewise, these reforms generated imbalances which, along with the changes in the world market conditions from 1998, led to the deepest crisis in Argentina's history. The inefficiency of state neoliberal policies in managing the crisis, based on fiscal adjustment to guarantee the continuity of external financing, led to an economic depression and a financial crash, sparking a mass rebellion and the end of convertibility.
