Influence of monomeric and polymeric structure on the physical properties of thermoplastic polyesters derived from hydroxy fatty acids

The physical properties of three vegetable oil derived medium and long chain poly(-hydroxy fatty ester)s (P(Me--OHFA)s), namely poly(-hydroxynonanoate) [P(Me--OHC9)], poly(-hydroxytridecanoate) [P(Me--OHC13)] and poly(-hydroxyoctadecanoate) [P(Me--OHC18)] (n = 8, 12 and 17, respectively), of the [-(CH2)(n)-COO-](x) polyester homologous series are presented. The effect of M-n (M-n 10-40 kg mol(-1)) and n on the crystal structure and thermal and mechanical properties of the P(Me--OHFA)s were investigated by wide-angle X-ray diffraction (WAXD), TGA, DSC, dynamic mechanical analysis (DMA) and tensile analysis and are discussed in the context of the [-(CH2)(n)-COO-](x) polyester homologous series, contrasted with linear polyethylene (PE). For all P(Me--OHFA)s the WAXD data indicated an orthorhombic crystal phase reminiscent of linear PE with crystallinity (X-c = 50%-80%) depending strongly on M-n. The glass transition temperature and Young's modulus for P(Me--OHFA)s increased with X-c. The DSC, DMA and TGA studies for P(Me--OHFA)s (n = 8, 12 and 17) indicated strong correlations between the melting, glass transition and thermal degradation behavior and n. The established predictive structure relationships can be used for the custom engineering of polyester materials suitable for specialty and commodity applications.

Survey of the nutritional recommendations and management practices adopted by feedlot cattle nutritionists in Brazil

Thirty-three feedlot cattle nutritionists were surveyed to evaluate the management practices and nutritional recommendations adopted by feedlots in Brazil. The web-based survey consisted of 81 questions that included: general information (n = 10); general commodity information (n = 15); use of coproducts (n = 5), roughage source and level (n = 5); adaptation methods (n = 7); feed mixers (n = 6); feeding management (n = 6); cattle management and type of cattle fed (n = 13); formulation practices (n = 9); information resources used for nutritional recommendations (n = 2); and additional questions (n = 3). In total, the 33 nutritionists were responsible for approximately 2,658,000 animals, and moreover, 65.5% of those participants had clients that feed less than 5000 animals yearly. Corn was the primary source of grain used in feedlot diets (87.9%) and cracking was the primary processing method recommended by nutritionists (57.6%). The average concentrate and roughage inclusion in finishing diets was 79.0% and 21.0%, respectively. The main challenges faced by nutritionists are the lack of available and precise equipment and lack of trained employees with respiratory diseases as the main health problem. This survey of nutrition and management practices should aid in the development of research for the feedlot industry in Brazil and similar tropical climates, as well as provide data to facilitate the broader application of future NRC models.

Educação Matemática e Sociedade

The paper's aim is to justify the creation of the line of research Mathematics Education and Society in the Graduate Program of Mathematics Education (PPGEM), UNESP (Rio Claro, SP). In a brief history of the constitution of the mathematics education community, the categories culture and society were emphasized. A brief summary of sociology is presented, drawing on classical sociologists and contemporary authors. The group EMsociedade is presented, and its purpose, which is to be part of the PPGEM to establish a space for discussions between students and supervisors from the Graduate Program, elementary and middle school teachers, and others who have interest in the subject. One of the arguments defended by the group is presented: institutionalized mathematical knowledge in the Twentieth Century is a commodity. Finally, some future considerations are outlined, including the expectation that the line of research Mathematics Education and Society will be included in the PPGEM.

Circuito espacial produtivo e círculos de cooperação dos café Fairtrade: análise da Associação dos Agricultores familiares do Córrego D'Antas (ASSODANTAS), Poços de Caldas/MG

The aim of this research project is to analyze the spatial productive circuit and circles of cooperation of Fairtrade coffee, taking as a case of study the Associação dos Agricultores Familiares do Córrego D'antas (ASSODANTAS), Poços de Caldas - MG. The main purpose is to analyze material flows (grains, supplies, etc.) established between geographically separated stages of production (production, exchange, distribution and consumption) and the relationships between the agents in order to analyze the organization and regulation of production of Fairtrade coffee. It is understood as the insertion of the Fairtrade ASSODANTAS to permit the creation of new production lines, adding value and providing greater identity and autonomy to their small farms, when compared with traditional coffee trade commodity

Gestão do ouro azul no contexto globalizado Neoliberal: bem econômico ou bem social?

The neoliberalism based on the Washington Consensus advised privatization as the most effective alternative for the management of natural resources. The question is what is prioritizing efficiency, market or welfare? The growing concern about the water issue has been highlighted in discussions in international policy debates, and what it turns out is the prominence of corporate and economic interests over social and environmental. The water is in crisis, there are several sources of popular conflicts around the world contrary to how this resource is being offered, as the Water War occurred in 2000 in the city of Cochabamba. It is necessary to respect its limitations to ensure their future availability and choose the best development model that favors the effectiveness of their control. The international proliferation of commercial vision concerning water stipulated privatization of their management as ideal rule, which increased rates, concentrated income, has not improved the quality nor promoted the conquest of equal access to water for most systems that provides these services, this is, privatization has not brought positive results that outweigh the harm of its implementation. Water is an essential commodity for life of living beings, in all its stages, basic reason to develop plans, rules and commitments that ensure its conservation and provide, as soon as possible, a valid alternative for the sustainable management in long term

Mudanças estruturais nas cadeias de valor na indústria do vestuário: um estudo de caso

In the early 1990 Gary Gereffi and Miguel Korzeniewicz published the book Commodity Chains and Global Capitalism. In the two decades prior to the publication, industrialization worldwide, had undergone significant changes, made more segmented and dispersed in certain regions. In the book, the authors produce a new set of categories to analyze the new standards for establishment and operation of global value chains, their organization, the new geography of manufacturing and the role of the countries in this scenario. Today, in the middle of the second decade of this century, world trade has expanded and multiplied continuously throughout this period, encouraged by reducing barriers and national borders promoted by 'peddlers' of this new era. The purpose of this study is to show that retailers are establishing purchasing offices in producing countries - or in nearby regions - to directly hire outsourced production

A escola na condição de não lugar

This article portrays the changes that schools and education have been undergoing since the Middle Ages to the contemporary era. Its main focus points at the subjective issues that underlie the school as educational space necessary for the maintenance of society. It ends by showing that the school currently is losing its historical, relational and identity function (essential issues to structure a society) and is becoming a non place (concept of Marc Augé), into an institution without apparent social function, held only as a still a consumable and profitable commodity.
