Análise antropotecnológica do desenvolvimento de novos produtos na produção artesanal : caso das rendeiras de bilro da Vila de Ponta Negra em Natal, RN

Brazilian craft production plays an important role in the generation of employment and income for many families in every state across Brazil. In Natal, Rio Grande do Norte, Brazil, among many types found, identifies itself with the production of bobbin-lace, still practiced in Ponta Negra Village for ancient craftswomens of city that try to preserve the art and tradition of bobbin-lace. This work presents the results of an analysis conducted based in concepts of anthropotechnology, on the effects of a design workshop held with bobbin-lace craftswomen in the village of Ponta Negra in July of 2006. The workshop was intended to propose a new concept of products and a new alternative for production in the activity of the craftswomen, on the premise that the laces could be used as a detail inserted into other industrial products such as shirts, bags, towels, etc. Evaluations after the workshop showed that none of the artisans continued to work, indicating that actions focused solely on products did not generate representative results in the production of bobbin-lace. Evaluations also indicated that knowledge about the artisan's personal and professional characteristics, organization, pace, workload, and cultural and historical issues that permeate the activity are essential to the success of technology transfer, particularly when the transfer affects the craft production as it relates to the inseparable aspects of the craftswomen's work and lifestyle

Impacto urbano ocasionado por empreendimentos da construção civil no entorno da zona de proteção ambiental (zpa-6), Vila de Ponta Negra, Natal/RN

The process of urbanization in recent decades has generated considerable seriousness of problems relating to the use and occupation physical environment of cities. The concentration of population, economic activities and technological standards have reinforced an existing urban environment highly degraded as a consequence of the development style that leads to the predatory use of natural resources. In this context, cities as centers of production and consumption, have the most serious problems of environmental degradation. This study investigated the impacts of the municipal building projects to large-scale vertical in the town of Vila de Ponta Negra, Natal-RN, given the proximity to the Environmental Protection Area (ZPA-6) and considering its environmental importance , scenic, landscape and tourism for the city of Natal-RN. The fragility of the licensing process and the failure of the assumptions in the analysis, objective and subjective, for the granting of environmental permits for the building construction projects, specifically those set out in the surroundings of the Environmental Protection Area (ZPA-6) and fundamental importance of landscape and tourism for the city of Natal, has aroused the concern of local people in and of itself the Government, faced with the probable impacts that will affect greatly the Vila de Ponta Negra. The methodology used to achieve the intended objectives will be the literature review, questionnaire to the surrounding population and the Government, as well as findings on the spot, through the photographic record. The beneficiaries of the license, if the entrepreneurs, have been affected because of the granting of licensing act of investing large amount of capital in the works. Additionally, with distrust of the population, since they are to discredit the public system of environmental management have guessed by the probability of imbalance to the environment and structural damage to the Vila de Ponta Negra, where such failure to support energy, lack of regular supply of water , lack of sanitation and access roads sufficient for the flow of motor vehicles in these areas, among other factors. Thus, this work will contribute to the diagnosis and solutions to the problem in question, so that the Government will effectively fulfill its social management of ecologically balanced environment of continuing urban development in Natal, Brazil

Rendeiras da Vila de Ponta Negra Natal/RN: o ensino da renda de bilro e do desenho como alternativa de continuidade da produção artesanal tradicional

This paper analyzes the development of Bobbin Lace and Design workshops, in the neighborhood of Vila de Ponta Negra (in Natal - RN, Brazil), which proposed contents and practices for its learning and teaching that would compose a possible model for a hybrid Workshop of Bobbin Lace and Lace Design. This research was based on Ergonomic Work Analysis, a methodology used by Ergonomics to analyze work in a wide approach, considering cognitive, social, organizational, as well as other aspects which are relevant to the study of the working situation, in terms of learning/teaching, as addressed on this paper. Some steps of the above mentioned methodology were followed in order to understand the activity of Bobbin Lace craftswomen, by means of bibliographical research centered on this activity. The instruments used for collecting data comprise of conversational actions, analysis of collective work, and spontaneous as well as provoked verbalizations. The adaptations performed in the process of learning/teaching Bobbin Lace for the achievement of Bobbin Lace and Design workshops became instrumental for the continuity of that tradition, attracting new apprentices to this art/craft causing to revitalize a network of handicraft economical activities linked to the Bobbin Lace production, such as the making of cushion, bobbins and trestles

Fósforo na produtividade e qualidade de sementes de feijão Carioca Precoce cultivado no período das águas

Common bean is an important crop in Brazilian agriculture and phosphorus (P) deficiency is one of the most yield limiting factors for this crop, thus plant P-deficiency can hamper the seed physiological quality. The objective of this study was to evaluate the productivity and quality of common bean seeds cv. Carioca Precoce cultivated during the rainy season in response to phosphate fertilizer. Six levels of P (0; 30; 60; 90; 120 and 150 kg of P2O5 had), with five replications, were applied in the groove of sowing as triple superphosphate. The seeds yield, at the experimental plot, was determined by the dry weight. Seed quality was evaluated through the following determinations: 100-seed mass, seed moisture content, germination, first counting, moisture content after accelerated aging, germination after accelerated aging, electrical conductivity, seedling emergence in the field and seedlings dry weight. The productivity of beans seeds 'Carioca Precoce' cultivated during the rainy season increased linearly as related to phosphorus rates. The 100-seed mass and the physiological quality of seeds have not changed by increasing of P levels.

Modos de ler, formas de escrever a literatura enquanto objeto da ficção de Enrique Vila-Matas

Este trabajo busca analizar cómo algunos aspectos presentes en la obra de ficción del escritor catalán Enrique Vila-Matas permiten pensar las prácticas de la escritura literaria contemporánea. A partir de una forma híbrida que reconsidera las relaciones tanto entre los géneros como entre los discursos crítico y de ficción, la obra del autor se propone reflexionar sobre sus propias posibilidades en el contexto sociocultural contemporáneo. De este modo, a través de una ficción que muchas veces adquiere los atributos del ensayo, Vila-Matas trae al centro de sus enredos la discusión de cuestiones relacionadas con los impases de una escritura que vuelve su atención para el destino de una tradición literaria desvinculada de los preceptos meramente mercadológicos contemporáneos. Su manera crítica de abordar la literatura y la experimentación en busca de nuevas posibilidades permite asociarlo tanto a Laurence Sterne como al proyecto literario de Jorge Luis Borges. Estos autores tienen propuestas que tratan de superar los límites del texto, ya que ahí está el deseo de acogerse a la ficción para demostrar la inestabilidad de los elementos de una cultura, apropiándose y desestabilizando los discursos y las claras distinciones entre los saberes. En este sentido, las diversas formas en que Vila- Matas se apropia de los textos de otros y construye una obra de carácter fuertemente intertextual denuncian jerarquizaciones y modos de circulación de textos que permiten aproximarse de la tensión existente entre temas como influencia, citación, prácticas de lectura y escritura

Escravidão na Vila do Príncipe, província do Rio Grande do Norte (1850/1888)

This dissertation presents a study on the slave population of Vila do Príncipe, from 1850 to 1888, based on the judicial and notarial collection of hand written documents as well as on the Reports of Presidents of the Province of Rio Grande do Norte. The issue that drives the research relates to the reproduction of slavery in a region of cattle breeding colonization. Therefore, the research aims to understand how in a peripheral socio-economic place (in Vila do Príncipe, cattle breeding Seridó) after the prohibition of the African slave trade, the slave relationships subsisted and structured themselves. In the sense, the research analyzed the dynamics of socio-economic slave units and their relationship with space, ownership structure and the slave family.

Liberdades possíveis em espaços periféricos: escravidão e alforria no termo da vila de Arez (séculos xviii e xix)

This paper discusses aspects of the slavery and emancipations in the village of Arez between the last quarter of the eighteenth century and the first decades of the nineteenth century. It seeks to identify the profile of the slaves and the emancipation possibilities in a peripheral region with few commercial activities, given that the most of the approaches about manumission consider towns and cities where the economic dynamics ware more pronounced, as places of higher possibilities of slaves working in diverse activities that allowed them to accumulate a reserve fund and thus buy their freedom. Therefore it was necessary to raise evidences of slavery in the case study, which was based on surveys of the eighteenth century, and the first decades of the nineteenth century and some population maps and civil records related to the early nineteenth century. The information about the manumission acts were analyzed based on writs of freedom registered in the village of Arez between 1774 and 1827 due to the absence of other documents about it. The registry books include all the documents of the Arez community; so, it was possible to observe what happened in rural localities, in the town, in the headquarters of the district and in the village of Goianinha. Based on information from the documents, it was possible to address some aspects of slavery like the predominant types of groups, the possible activities in which slaves were inserted and the profile of the freed slaves, the emancipation modes and, therefore, discuss the possible relations ship between the colonial space and manumissions and between masters and slaves

Vende-se uma vila: análise intra-urbana das vilas na Vila de Ponta Negra e no bairro de Nova Descoberta - Zona Sul de Natal

This dissertation is about low-income rental housing vilas in the South Zone in the city of Natal. Vilas are a string of houses, built privately in an urban plot of land, usually a backyard, facing a narrow street beco. This type of housing is originated in the 19th century in the Brazilian scenario. In Natal, this has become more popular since the late 1960s. This study is aimed at analyzing the urban integration of the vilas, considering that these house a low income population, vis à vis the speedy development of Natal s most economically dynamic area. The study starts with a discussion of the production of space, taking into consideration categories such as use value, exchange value, commodity and land rent. Field work was undertaken through structured interviews with dwellers of vilas in Nova Descoberta and Ponta Negra neighbourhoods. Owners of vilas were also interviewed. Data collected indicated worrisome housing conditions. Vilas, in the areas researched, are increasingly becoming unwelcome, constituting guetos in a place where landscape is changing rapidly. Gentrification is fast under way, first because of rise in rent and taxes; second because of general rise in living costs

Análise espacial do risco de leptospirose canina na Vila Pantanal, Curitiba, Paraná

A leptospirose é uma grave zoonose associada às áreas de baixa renda dos centros urbanos. Embora roedores urbanos sejam considerados como principal reservatório para a leptospirose, o cão também pode desenvolver a doença e se tornar carreador assintomático. O objetivo do presente trabalho foi utilizar a metodologia estatística baseada na teoria de processos pontuais espaciais, buscando identificar a forma como se distribuem os cães sororreagentes para a leptospirose e seus determinantes de risco em uma vila na cidade de Curitiba. A análise do modelo possibilitou identificar as regiões de sobre-risco, onde o risco de soropositividade canina à leptospirose é significativamente maior. A relação significativa do efeito espacial no desenvolvimento da doença, além das variáveis estudadas, revela que não apenas um, mas a ação conjunta dos fatores relacionados ao animal, ao proprietário e ao ambiente influencia o risco maior da doença nos locais de maior efeito espacial. O resultado da análise indica claramente os territórios em maior risco na região da Vila Pantanal, possibilitando o planejamento de ações mais específicas e dirigidas a essas áreas em um contexto de vigilância da saúde.

NÍVEIS DE MAGNÉSIO em SOLUÇÃO NUTRITIVA E O DESENVOLVIMENTO do FEIJOEIRO (Phaseolus vulgaris L. cv Carioca): AVALIAÇÃO DE PARÂMETROS BIOMÉTRICOS

O presente estudo teve como objetivo avaliar a influência dos níveis de magnésio sobre a altura, número de folhas e frutos e área foliar do feijoeiro (Phaseolus vulgaris L. cv Carioca), que constituem seus parâmetros biométricos. Empregou-se a solução nutritiva nº 2 de Hoagland & Arnon, modificada pela variação da concentração desse mineral, que estabeleceu a diferença entre os tratamentos. em cada vaso, com capacidade para 6 litros, foram cultivadas 3 plantas. O experimento foi inteiramente casualizado, com 3 repetições, em esquema fatorial, com 5 níveis de magnésio e 5 colheitas, realizadas a intervalos de 14 dias. As plantas apresentaram aumento do número de folhas e da área foliar, na 3ª e 4ª colheitas, quando nutridas com 2,4 ppm de magnésio e aumento de altura e número de folhas, na 3ª colheita, naquelas submetidas a 24,3 ppm. Aumento do número de folhas, na 3ª colheita, foi observado em plantas nutridas com 72,9 ppm e na 3ª e 5ª colheitas naquelas submetidas a 97,2 ppm. Estes resultados sugerem que, nas condições do experimento, 2,4 ppm de Mg foram suficientes para manter o desenvolvimento adequado dos feijoeiros e que o nível ideal deste mineral para crescimento e desenvolvimento das plantas estaria entre 2,4 e 24,3 ppm.

Anatomia de ápices radiculares de feijão cv. carioca submetidos a níveis de boro em solução nutritiva

Foram estudadas as alterações anatômicas em ápices radiculares do feijoeiro (Phaseolus vulgaris L. cv. Carioca), quando submetidos a diferentes níveis de boro em solução nutritiva. Através de um experimento inteiramente casualizado, foram realizados três tratamentos como se segue: T1 0,50 mg L-1 de boro (testemunha); T2 0,25 mg L-1 de boro (nível intermediário); T0 omisso em boro; sendo feitas amostragens em três estágios sucessivos de desenvolvimento da planta, no decorrer de seu ciclo. As alterações foram avaliadas efetuando-se secções longitudinais de ápices radiculares, sendo analisados comparativamente por meio de estudo cito-histológico com o emprego de microscópio de luz. Considerando como testemunha as plantas submetidas ao nível de 0,50 mg L-1 de boro na solução nutritiva, pôde-se verificar que a omissão desse micronutriente, na solução nutritiva, provocou inibição da divisão e alongamento celular, hipertrofia de células, desorganização de elementos vasculares em raiz, impedindo que a planta completasse seu ciclo, morrendo ao redor do 55o. dia após o transplante. O nível de 0,25 mg L-1 de boro, na solução nutritiva, embora tenha provocado desorganização no ápice radicular, não impediu o desenvolvimento da planta.

Determination of amylase activity in cotyledons of Phaseolus vulgaris L. cv. carioca

Determination of α- and β-amylase activity in the extracts of cotyledons of Phaseolus vulgaris L. cv. cariocawas done using selective inactivation of α-amylase by lowering the pH of the incubation medium or by the use of EDTA as inhibitor or selective inactivation of β-amylase by the use of HgCl2 or by heating to 70ºC in the presence of CaCl2; and still by using the reagent starch azure for specific determination of α-amylase. Results indicated that the methods used were inappropriate in this case, being indicated the determination of total amylase activity.

ABSORÇÃO DE CÁDMIO E CRESCIMENTO DEFEIJOEIRO (Phaseolus vulgaris, L. cv carioca)

A absorção de cádmio e seus efeitos no crescimento de feijoeiro (Phaseolus vulgaris, L. cv carioca) foi estudada em solução nutritiva completa de Hoagland & Arnon acrescida de doses de cádmio com concentrações entre 10 e 200 mmol L-1. Os teores de cádmio em folhas e raízes aumentaram à medida que aumentou a concentração de cádmio na solução nutritiva. Os teores de cádmio nas raízes foram maiores que nas folhas. Os resultados mostraram que a inibição do crescimento de folhas e raízes provocadas pela presença de cádmio são reversíveis.

Magnesium levels in nutrient solution and common bean (Phaseolus vulgaris L cv Carioca) development. Evaluation of the growth relations and assimilate partitioning

The effect of magnesium levels in nutrient solution upon relation between shoot and root, leaf weight ratio and assimilate partitioning of common bean (Phaseolus vulgaris L. cv Carioca) was studied. Bean plants (3 per pot) were grown in 6 l pots containing Hoagland & Arnon n. 2 solution modified to obtain 2.4, 24.3, 48.6, 72.9 and 97.2 ppm of magnesium. The experimental design was a completely randomized factorial replicated 3 times with 5 levels of magnesium and 5 samplings wich were done forthnightly. Therefore, it may be suggested that the 48.6 ppm of magnesium level proposed by Hoagland & Amen (1950) is the best choice for the common bean, according to the conditions of this experiment. Magnesium concentrations over 48.6 ppm didn't show significant alterations of the evaluated parameters. Nutrient solution with 2.4 ppm of magnesium content provides higher efficiency to the common bean plants during almost all its cycle, except the final of the reproductive phase. These results suggest that magnesium concentration increased to 48.6 ppm, in the cycle final perhaps could increase the productivity.
