Questionnaire and survey methodology. Saint Lucia: Survey of living condition and household budgets 2005/2006

This manual documents some of the material related to the Survey of Living Conditions and Household Budgets (SLC/HBS) conducted in Saint Lucia by the Kairi Consultants Limited and National Assessment Team between 2005 and 2006. The SLC/HBS is a sample survey which generates data on households and individuals in the country. The main objectives of this survey were (i) to collect information from households on their expenditure patterns, income and other characteristics and; (ii) to revise the 'average shopping basket' used in constructing the Consumer Price Index (CPI) for the country, and the relative weights of the items in the basket. The survey also provided valuable data for an assessment of the impact of socio-economic policies on the living conditions of the resident population in Saint Lucia. Further, data on households gathered in the survey also provide valuable inputs for the compilation of the country's National Accounts statistics relating to the household sector. This manual was developed by the Economic Commission for Latin America and the Caribbean (ECLAC) – Subregional Headquarters in the Caribbean as a supplementary document for the Caribbean Household Surveys Database (CHSD). The main components of this manual include survey methodology and the questionnaires used for data collection. The latter are included in the annex at the end of the document. All information contained therein was provided by the Statistics Department in Saint Lucia. The ECLAC Subregional Headquarters for the Caribbean is pleased to acknowledge the Saint Lucia Statistics Department for graciously consenting to the use of their surveys and metadata under the project Improving Caribbean Household Surveys. Due recognition must also be given to the Statistics and Economics Projection Division at ECLAC (Santiago) who provided guidance in the standardization of the datasets and the creation of the Caribbean Household Surveys Databank.

An automatic methodology for obtaining optimum shape factors for the radial point interpolation method

In this letter, a methodology is proposed for automatically (and locally) obtaining the shape factor c for the Gaussian basis functions, for each support domain, in order to increase numerical precision and mainly to avoid matrix inversion impossibilities. The concept of calibration function is introduced, which is used for obtaining c. The methodology developed was applied for a 2-D numerical experiment, which results are compared to analytical solution. This comparison revels that the results associated to the developed methodology are very close to the analytical solution for the entire bandwidth of the excitation pulse. The proposed methodology is called in this work Local Shape Factor Calibration Method (LSFCM).

Separation of satured and unsaturated fatty acids from palm fatty acids distillates in continuous multistage countercurrent columns with supercritical carbon dioxide as solvent: a process design methodology

In this work the separation of multicomponent mixtures in counter-current columns with supercritical carbon dioxide has been investigated using a process design methodology. First the separation task must be defined, then phase equilibria experiments are carried out, and the data obtained are correlated with thermodynamic models or empirical functions. Mutual solubilities, Ki-values, and separation factors aij are determined. Based on this data possible operating conditions for further extraction experiments can be determined. Separation analysis using graphical methods are performed to optimize the process parameters. Hydrodynamic experiments are carried out to determine the flow capacity diagram. Extraction experiments in laboratory scale are planned and carried out in order to determine HETP values, to validate the simulation results, and to provide new materials for additional phase equilibria experiments, needed to determine the dependence of separation factors on concetration. Numerical simulation of the separation process and auxiliary systems is carried out to optimize the number of stages, solvent-to-feed ratio, product purity, yield, and energy consumption. Scale-up and cost analysis close the process design. The separation of palmitic acid and (oleic+linoleic) acids from PFAD-Palm Fatty Acids Distillates was used as a case study.

Natureza capitalista versus natureza orgânica: o advento da ALCOA e a mobilização e organização das comunidades de Juruti no baixo-amazonas paraense

A tese teve como objetivo apresentar a leitura e a análise dos processos que levaram conquistas inéditas às comunidades em Juruti, no baixo amazonas, região localizada no estado do Pará. Juruti foi palco de conflitos, negociações, acordos e conquistas frente ao grande empreendimento de extração mineral desenvolvido pela ALCOA. Essas conquistas são resultados de fatores externos e internos. O externo foi marcado por um conjunto favorável, relacionado ao governo de esquerda no âmbito federal, estadual e municipal; e por um arcabouço institucional jurídico que reconhece os direitos coletivos e territoriais, a emergência da questão ambiental e a presença da Igreja Católica, por meio do trabalho pastoral das Irmãs Franciscanas de Maristella, orientadas pela teologia da libertação e a pedagogia do oprimido. No âmbito interno, prevaleceu o caráter tradicional, a vivência comunitária e as práticas coletivas, como o puxirum, que possibilitaram a constituição de um território organizado e capaz de desencadear processos de mobilização e resistência com a mínima fragmentação e cooptação. O apoio de diferentes contribuições teóricas da sociologia, da antropologia entre outras facilitaram a nossa leitura do processo vivido no território de Juruti, assim como as abordagens do pós-desenvolvimento. A metodologia da pesquisa é de natureza exploratória, descritiva e explicativa, articulada com técnicas de campo como: a coleta de informações e entrevistas com pessoas-chave, documentos de empresa, comunidades, Igreja Católica e outros. Tal procedimento buscou compreender os discursos empreendidos pelos autores presentes em Juruti. Identificamos a estreita relação da Igreja com movimentos e grupos que encamparam a luta na região de Juruti junto a ALCOA, por meio da Congregação das Irmãs Franciscana de Maristella, em virtude da sua história de inserção no local, e de sua opção em defesa da tradicionalidade das comunidades. Também percebemos um governo favorável, aberto ao diálogo, à existência de uma conjuntura política favorável; a preocupação da sociedade global com o meio ambiente; a existência de um arcabouço jurídico com o reconhecimento de direitos institucionalizados, como os direitos territoriais. Com tal abordagem, conclui-se que diante das múltiplas ações dos grandes projetos é preciso articular oportunidades e potencialidades de forma a buscar os caminhos de superação da invisibilidade atribuída às comunidades pelo Estado e grandes empreendimentos econômicos. Os aspectos organizativos em Juruti, assim como sua articulação, levaram à superação dos mecanismos de dominação, padronização e invisibilidade das comunidades tradicionais na Amazônia.

Ethanolysis optimisation of Jupati (Raphia taedigera Mart.) oil to biodiesel using response surface methodology

In this work, the transesterification of jupati (Raphia taedigera Mart.) oil using ethanol and acid catalyst was examined. The production of biodiesel was performed using a central composite design (CCD). A range of values for catalyst concentration (1 to 4.21%), temperature (70-80 °C), and the molar ratio of alcohol to oil (6:1-13.83:1) were tested, and ester content, viscosity, and yield were the response variables. The synthesis process was optimised using response surface methodology (RSM), resulting in the following optimal conditions for the production of jupati ethyl esters: a catalyst concentration of 3.85% at 80 °C and an alcohol-to-oil molar ratio of 10:1.

Development of a Methodology and Evaluation of Pesticides Against Aceria litchii and Its Predator Phytoseius intermedius (Acari: Eriophyidae, Phytoseiidae)

The litchi erineum mite, Aceria litchii (Keifer), is the major pest of litchi, Litchi chinensis Sonnerat (Sapindaceae). This study evaluated the effect of 11 pesticides on the survival of A. litchii as well as on the survival and reproduction of Phytoseius intermedius Evans& McFarlane, the predator most found in association with it in Brazil. The containment of A. litchii in small petri dishes whose bottoms were covered with a solidified paste made of a mixture of gypsum and activated charcoal (9: 1 in volume), kept humid, was shown to be adequate for this type of study. For the evaluation of the effect of pesticides on A. litchii, mites leaving the erinia from the pieces of litchi leaves (removed from the plants approximate to 24 h earlier) were sprayed under a Potter tower and immediately transferred to the 2.5-cm-diameter petri dishes. After 2, 12, 24, and 48 h of the application, the dishes were examined to evaluate the mite survival. The four pesticides causing the highest levels A. litchii mortality, as well as azadirachtin, were tested for the effect on P. intermedius. For this test, experimental units consisted of discs of uninfested litchi leaves also sprayed under a Potter tower before introducing the predators. Survival and oviposition of the predator were evaluated every 24 h for 5 consecutive days; viability of the eggs laid was also evaluated. Highest mortality of A. litchii occurred with the application of fenpyroximate, sulfur, abamectin, and hexythiazox. Azadirachtin was considered moderately harmful to the predator P. intermedius, whereas other pesticides were classified as harmful. Despite the low efficiency of azadirachtin in the control of the pest, its relative selectivity to P. intermedius would encourage the evaluation on field condition, especially for use in organic production systems.
