Inclusion of Low Income Sectors in Latin American Agribusiness

We examine three case studies on agribusiness ventures that have included low income sectors (LIS) into value creation activities to reduce poverty in Latin America. While the goal for each agribusiness is economic profit, we find that this goal is not inconsistent with wealth creation among LIS. We use the agribusiness chain analytical framework to identify the roles played by LIS in the ventures studied, and we explore the ways in which LIS inclusion has influenced the performance of the agribusiness chains and contributed to their competitiveness.Agribusiness, Poverty reduction, Latin America, Agribusiness, Food Consumption/Nutrition/Food Safety, Food Security and Poverty,

Strategic Paradigms of Social and Environmental Balance

Complaints about the socio-environmental relationship have become prominent, requiring the academy to deepen its studies on the strategic paradigms of sustainability. The objective of this essay is to study the conceptions of strategic paradigms along the path of social and environmental balance, with the specific objectives of raising the paradigms under social, economic, environmental and institutional aspects (1), analyzing the strategic paradigms that can favorably promote equilibrium (2), and critiquing the discourse of society, aiming at social and environmental balance (3). The elaboration of this work is based on the Institutionalist Theory that prescribes the set of individual behaviors, beliefs and values, processed in accordance with the individuals’ perception, and in their interpretative capacity of the reality in which they are inserted. This qualitative research is elaborated through the Method of Content Analysis, and applies procedures of bibliographical survey and documentary treatment of the social discourse that substantiates sustainable paradigms. As a result of the critical analysis, it is verified that the discourses and behaviors of the social agents do not contribute to the social-environmental balance. Then, new proposals of strategic paradigms which are useful for reflective actions and universal meanings are incorporated here. The expectation is to redirect the individual to behavioral reflections, through a learning that is coherent with the confrontation of the planetary emergency. It is also indicated for the spirit of preservation and conservation of the environment, in which the relationship with the social, economic and institutional will bring the desired balance for generations. This study represents those interested in the discussion about the socio-environmental relationship, and those involved in learning about sustainability and orientation towards ethical posture

Expression and characterization of a recombinant cysteine proteinase of Leishmania mexicana

A major cysteine proteinase (CPB) of Leishmania mexicana, that is predominantly expressed in the form of the parasite that causes disease in mammals, has been overexpressed in Escherichia coli and purified from inclusion bodies to apparent homogeneity. the CPB enzyme, CPB2.8, was expressed as an inactive pro-form lacking the characteristic C-terminal extension (CPB2.8 Delta CTE). Pro-region processing was initiated during protein refolding and proceeded through several intermediate stages. Maximum enzyme activity accompanied removal of the entire pro-region. This was facilitated by acidification. Purified mature enzyme gave a single band on SDS/PAGE and gelatin SDS/PAGE gels, co-migrated with native enzyme in L. mexicana lysates, and had the same N-terminal sequence as the native enzyme. the procedure yielded > 3.5 mg of active enzyme per litre of E. coli culture.Univ Glasgow, Inst Biomed & Life Sci, Div Infect & Immun, Glasgow G12 8QQ, Lanark, ScotlandUniv Glasgow, Wellcome Ctr Mol Parasitol, Glasgow G11 6NU, Lanark, ScotlandCarlsberg Lab, Dept Chem, DK-2500 Copenhagen, DenmarkEscola Paulista Med, Dept Biophys, BR-04034 São Paulo, BrazilEscola Paulista Med, Dept Biophys, BR-04034 São Paulo, BrazilWeb of Scienc

Descrição de sistemas de criação tradicionais de ovinos da Nhecolândia, Pantanal, MS.

Este trabalho tem como objetivo principal resgatar o conhecimento empírico sobre o sistema de criação tradicional de ovinos no Pantanal, caracterizando-o e descrevendo-o a partir de oito fazendas da sub-região da Nhecolândia, Pantanal, MS. Devido a crescente demanda do mercado por carne ovina, os produtores do Pantanal podem diversificar a produção animal. A região apresenta potencial para a produção de ovelhas pantaneiras para cruzamentos no planalto, produção de cordeiros (orgânicos), produção de subsistência da fazenda, entre outros. Para tanto, há a necessidade de desenvolver práticas sustentáveis de manejo da ovinocultura no Pantanalbitstream/item/80589/1/CT94.pd

Blade Tip Pressure Measurements Using Pressure Sensitive Paint

This paper discusses the application of pressure sensitive paint using laser-based excitation for measurement of the upper surface pressure distribution on the tips of rotor blades in hover and simulated forward flight. The testing was conducted in the Rotor Test Cell and the 14- by 22-ft Subsonic Tunnel at the NASA Langley Research Center on the General Rotor Model System (GRMS) test stand. The Mach-scaled rotor contained three chordwise rows of dynamic pressure transducers for comparison with PSP measurements. The rotor had an 11 ft 1 in. diameter, 5.45 in. main chord and a swept, tapered tip. Three thrust conditions were examined in hover, C(sub T) = 0.004, 0.006 and 0.008. In forward flight, an additional thrust condition, C(sub T) = 0.010 was also examined. All four thrust conditions in forward flight were conducted at an advance ratio of 0.35

Deployment of a Pressure Sensitive Paint System for Measuring Global Surface Pressures on Rotorcraft Blades in Simulated Forward Flight

This paper will present details of a Pressure Sensitive Paint (PSP) system for measuring global surface pressures on the tips of rotorcraft blades in simulated forward flight at the 14- x 22-Foot Subsonic Tunnel at the NASA Langley Research Center. The system was designed to use a pulsed laser as an excitation source and PSP data was collected using the lifetime-based approach. With the higher intensity of the laser, this allowed PSP images to be acquired during a single laser pulse, resulting in the collection of crisp images that can be used to determine blade pressure at a specific instant in time. This is extremely important in rotorcraft applications as the blades experience dramatically different flow fields depending on their position in the rotor disk. Testing of the system was performed using the U.S. Army General Rotor Model System equipped with four identical blades. Two of the blades were instrumented with pressure transducers to allow for comparison of the results obtained from the PSP. Preliminary results show that the PSP agrees both qualitatively and quantitatively with both the expected results as well as with the pressure taps. Several areas of improvement have been indentified and are currently being developed

Feminism And Marginal Sectors: Achievements And Setbacks In A Difficult Dialog

The feminist movement has given voice to the demands of women and assured their conquests and demands. But not all groups of women have been equally recognized. Groups with greater social marginalization have the greatest difficulties inserting their demands within the hegemonic lines of feminism. There are currently polemics about how to approach themes such as sexual work and female crime. © 2016, Universidade Estadual de Campinas UNICAMP. All rights reserved.20164
