Vicus Judæorum: os judeus e o espaço urbano no Recife neerlandês

This work broaches the participation of the Jewish community in the urban expansion of Recife, Brazil, during the Dutch period (1630-1654). With the arrival of the Dutch, the village of Olinda, former capital of Pernambuco, was destroyed and Recife received the juridical statute of city (stad), becoming the capital of Dutch Brazil or New Holland. It became the main West Indians Company s entrepot in South Atlantic, serving as naval base, port of call for ships, and point of export of the sugar production of Pernambuco, and import of European goods and African slaves. In order to such administrative, military and economic functions be carried out, the sand isthmus where Recife used to stay, and the fluvial island of Antônio Vaz, received improvements of many sort. The Dutch hydraulic technology was put in practice, with a posture of opposition between civilization and nature. Among military works and production of urban equipments, the rivers shores were land-filled, canals were built, bridges were lifted, and hundreds of buildings were erected. The civil Dutch population of Recife engaged in the process of production of physical space, which brought a sense of collective action towards the formation of the urban, or burgher, community. From the physical to the social space, there was an effort towards Dutch cultural standards in the urban environment. The Zur Israel Jewish community, formed by private civilians, it is, nonemployees of the WIC, engaged in those processes. It produced physical space through the land-filling and improvement of non healthy areas, and was also responsible for the construction of a significant section of the town s buildings and some of urban equipments, such as stores, markets and slave-warehouses, making more dynamic their economical activities. But their social traffic was due to the adaptation of their behavior to the standards of Dutch sociability. Thus, the community body made itself part of the social body. Disposing of internal selfregulation, it produced spaces with their cultural references cemetery, synagogue, texts enjoying benefits of the government. Zur Israel inscribed itself in the universal history of the Jews as the first community of Americas, and had a fundamental part on the emancipation of Jews within Western society

Agricultura familiar: uma perspectiva da qualidade de vida do produtor rural orgânico da Paraíba

Knowledge of quality of life is a very complex and rich in cultural and subjective dimensions, understood in a broad sense and multivariate theme. Considering the rural areas from agriculture, it is observed that the production standard defines significant changes in the environmental context and the quality of life of rural workers. To explain the relationship between quality of life and Family Organic Agriculture, we sought to analyze the quality of life of the organic family farmer, after change in agricultural management. The research, based on a procedure exploratory study supported the articulation theoretically constructed, showed their relevance and allowed to delimit with greater security, the central question of work. The WHOQOL - 100 treated the instrument of research on quality of life that directed the field study with organic farmers from the town of Lagoa Seca / PB. Farmers and family members are from rural regions Almeida, Alvinho, Lagoa de Barro, Lagoa Gravatá, Oiti and Pau Ferro. The average time is 39 years farming and organic family farm is 16 years. In the analysis work was found that the process of production of vegetables and fruits is divided into 08 steps and with respect to workloads observations showed the presence of: physical loads, mechanical stresses, psychological burden and ergonomic factors. Most farmers reported symptoms were fatigue and cramps in the legs . Regarding the quality of life was noticed that the Psychological Domain contributed positively to the quality of life with mean and standard deviation (17.83 ± 12.78) and Domain Environment negatively contributing to the quality of life of this group (9.00 ± 6.82). We conclude that the practice of Family Organic Agriculture should be seen as an effective strategy in promoting quality of life and social values in between, since it presents environmental sustainability with regard to life and socio-cultural diversity of populations

Infâncias :o lugar do lúdico nas tramas do trabalho infantil

Considering infancy as the socio-historic construction required from the researcher, not only gives problems to the natural character of the human development, that for a long period in the history of psychology has sown to be predominant, but before anything assumes the position in which the vision of the social condition, i.e., for the contexts of the insertion of the human being, is predominant. In this sense, it is not possible to talk about infancy in the singular, once the different developmental contexts enable different forms of immersion in the daily experiences, amongst which this research focuses on the experience of the ludic. According to various theories of development amongst which we emphasize the socio-historic, this element brings important contributions in the processes of the human being constitution. From the legal aspect this recognition is present in the Code of Practice of the Child and Adolescent which considers playing to be a right of the child. However, the childhood of many children have this aspect affected by many factors. It is in the context of this discussion that we developed this research which has as its objective investigate how children in a working environment experience playing on a daily basis. Four children, girls, took part in this research, who develop activities in the process of the usage of cashew nuts. We used interviews, observations, photographs and drawings. The perspective of analysis which guided this task is based on socio-historic and discursive studies. In this way, the elements which constitute the child s discourse, formed from the corpus were: be a child, the ludic culture, the work in the child s life and the perspective of future and change. The participants discourse showed to be conflicting, contradictory, arisen from a specific ideological formation. In the children s daily routine it was possible to verify that there is an existence of a rich ludic culture, even if it is lived in few moments of the day in consequence of the workload

Utilização de rejeitos de Caulins na Síntese de Zeólita A

Three studies were performed using tailings kaolin for the synthesis of zeolite A. The first synthesis of zeolite A was performed using a kaolin waste generated from the beneficiation of kaolin for paper production process was studied. The kaolin waste was thermally activated at a temperature range of 550-800°C. For comparison was performed a synthesis pattern of Zeolite A(procedure IZA). The prepared materials were characterized by 27Al MAS NMR, X-ray diffraction and scanning electron microscopy with microprobe rays. The pre-tramento proved to be the most appropriate and suitable temperatures are between 600 and 700°C. Observed the formation of zeolite A in all materials, reaching 52% crystallinity, and the presence of phase sodalite and amorphous material. The second study was the use of a highly reactive metakaolin originating from the Jari region in the synthesis of zeolite A by a new method of hydrothermal synthesis. The zeolite is obtained pure and highly crystalline employing the Jari kaolin calcined at 600 ° C for 2h when the transformation to metakaolin occurs. Get to zeolite phase A at 4pm. The best crystallization time was of 24 h afforded a crystallinity of 67.9%. The third study was the evaluation of the NaOH / metakaolin and crystallization time on the synthesis of zeolite NaA from a sample of kaolin waste, named Kaolin Coverage. The experiments were performed using statistical design (axial points) and rejoinder the center point. The samples were characterized by X-ray diffraction (XRD), scanning microscopic analysis and chemical analysis using an EPMA microprobe. The results showed that a relationship exists between the amount of NaOH added and the crystallization time. The experiment performed using the lowest ratio NaOH / metakaolin (0.5) and shorter (4 h) produced an amorphous material. The increase ratio of NaOH / metakaolin and crystallization time leads to formation of a more crystalline NaA phase, but the presence of phase with sodalite as impurities

Preparo do solo, irrigação por aspersão e rendimento de engenho do arroz de terras altas

O rendimento de engenho obtido após o beneficiamento industrial é um parâmetro importante durante a fase de comercialização do arroz e pode ser influenciado pelas práticas culturais realizadas durante o período de cultivo. O presente trabalho teve como objetivo avaliar o rendimento de benefício, rendimento de inteiros e grãos quebrados de cultivares de arroz de sequeiro em função do preparo do solo e da irrigação por aspersão na região de Selvíria - MS, durante os anos agrícolas de 1997/98 e 1998/99. O solo do local é do tipo Latossolo Vermelho álico, textura argilosa e os tratamentos consistiram na combinação de três cultivares de arroz (IAC 201, Carajás e Guarani), com três sistemas de preparo do solo (arado de aiveca + grade niveladora, escarificador + grade niveladora e grade pesada + grade niveladora) e três níveis de irrigação por aspersão (sequeiro e duas lâminas de água), com quatro repetições. O cultivar IAC 201 apresenta maior rendimento de benefício e o Carajás destaca-se dos demais em rendimento de inteiros; os diferentes sistemas de preparo utilizados praticamente não interferem no rendimento de engenho; a irrigação por aspersão aumenta o rendimento de benefício e o rendimento de inteiros, principalmente em ano com ocorrência de veranico.

Aleitamento materno e alimentação complementar em crianças menores de um ano: chamada neonatal, RN, 2010

Avaliar os dados de aleitamento materno e alimentação complementar de crianças menores de um ano, do Rio Grande do Norte (RN), de acordo com o que é preconizado pelas políticas e ações de alimentação e nutrição. Métodos: Foi analisado o banco de dados da Chamada Neonatal do RN, pesquisa realizada pelo Ministério da Saúde em 2010. A amostra analisada foi de 837 pares mãe/filho que responderam ao questionário da pesquisa nos municípios investigados. Foram analisadas a prevalência de dados de aleitamento materno exclusivo (AME), na primeira hora de vida, parcial (AMP) e total (AMT), assim como dos alimentos ingeridos, pelas crianças, nas ultimas 24 horas anterior a entrevista. As frequências e médias foram feitas pelo comando Complex samples, no SPSS® 20.0, com IC95%. Foram estimadas as medianas de tempo de AME e AMT, assim como a mediana de tempo de introdução dos grupos de alimentos consumidos, em relação a idade da criança pelo método de probitos. Foi feita associação das probabilidades de tempo de AME e AMT com as variáveis sociodemográficas e de pré-natal (p<0.05). Resultados: Foram encontradas médias de idades de 5,28 ± 3,4 meses e 25,9 ± 6,4 anos, para crianças e mães, respectivamente. A prática de aleitamento na primeira hora de vida foi considerada boa (66,6%) e o percentual de AME (20%) razoável,segundo a Organização Mundial da Saúde, 2008. Mais da metade das crianças (55,1%) estavam em AMP. No total 60% estavam sendo amamentadas (AMT) ao final do primeiro ano de vida. O AME teve mediana de 63 dias e AMT de 358 dias. Estes dados não se diferenciaram muito entre a capital e os municípios do interior. A maioria das mães entrevistadas (73,8%) referiu ter tido orientação sobre aleitamento no pré- natal, tendo associação (p=0,03) com a probabilidade de tempo de AME, porém com pouca explicabilidade (R2= 0,011). Água ou chá, alimentos lácteos, frutas, legumes e verduras foram introduzidos precocemente com medianas menores que 180 dias. O aleitamento tende a diminuir e os alimentos tendem a aumentar o consumo de acordo com a idade da criança, com aumento exponencial do grupo calorias vazias . Conclusões: Conclui-se que mesmo com maioria das crianças amamentadas até um ano de vida, poucas estavam em AME e introduziram alimentos precocemente, não tendo resultado satisfatório frente ao preconizado pelas políticas públicas de alimentação e nutrição

Custo de produção de amora-preta em região tropical

O cultivo da amora-preta é recente no Brasil. A espécie apresenta elevada adaptabilidade, baixa exigência em frio, facilidade de manejo, rusticidade e pouca utilização de defensivos agrícolas. É uma fruta que vem despertando elevada atenção dos consumidores devido à presença de compostos fenólicos com propriedades antioxidantes. Com este trabalho, objetivou-se analisar o custo de produção do cultivo da amora-preta, em primeiro ano de produção. Para estimar a matriz de coeficientes técnicos e os custos de produção, em 2007, os preços de venda foram levantados junto a um produtor, e o restante das informações foi obtido de um experimento. de acordo com os dados e os cálculos de custos, a primeira produção da cultura foi de 3.000 kg.ha-1, com custo de implantação e condução, no primeiro ano, de R$ 8.710,63, e no segundo ano, apresentou custo de R$ 6.467,50. o custo de produção foi relativamente baixo comparado com outras frutíferas perenes cultivadas na região, evidenciando que esta atividade pode ser mais uma alternativa de renda para agricultura familiar.

Características físicas e químicas de frutos de maracujazeiro-amarelo enxertado em três porta-enxertos

O mercado de frutas frescas do maracujá-amarelo valoriza a qualidade interna e externa dos frutos. Assim, este trabalho teve o objetivo de avaliar o efeito do porta-enxerto e do tipo de enxertia na qualidade dos frutos de maracujazeiro-amarelo (Passiflora edulis Sims). O experimento foi conduzido no município de Adamantina-SP, no período de abril de 2006 a junho de 2007, adotando-se o delineamento em blocos ao acaso, em esquema fatorial 3 x 2 + 1 tratamento adicional, com quatro repetições. Os porta-enxertos avaliados foram: P. edulis (maracujá-amarelo), P. alata (maracujá-doce) e P. gibertii (maracujá-giberti), em dois tipos de enxertia: hipocotiledonar e convencional por garfagem tipo fenda cheia e um tratamento adicional, sem enxertia. Utilizou-se como copa o maracujazeiro-amarelo (Passiflora edulis Sims). Avaliaram-se o comprimento, o diâmetro, a massa fresca e a classificação dos frutos no período de novembro de 2006 a abril de 2007, a massa e a espessura da casca dos frutos, o rendimento do suco, o teor de sólidos solúveis totais (SST), a acidez total titulável (ATT) e o ratio (SST/ATT) dos frutos no mês de dezembro de 2006. O diâmetro e a massa fresca de frutos obtidos de plantas enxertadas sobre P. gibertii foram inferiores em relação aos de plantas pé-franco e aos de plantas enxertadas sobre P. alata. Os maiores comprimentos de frutos foram encontrados em plantas não enxertadas. Os porta-enxertos utilizados não influenciaram no teor de SST, na ATT e no ratio. O método de enxertia não interfere no diâmetro, no comprimento, na massa fresca dos frutos, na massa e na espessura da casca, no rendimento do suco e no teor de SST.

Avaliação de impacto ambiental e gestão dos recursos natuarias no estuário Apodi Mossoró, nordeste do Brasil

The aim of this study is to investigate the eco-environmental vulnerability, its changes, and its causes to develop a management system for application of eco-environmental vulnerability and risk assessment in the Apodi-Mossory estuary, Northeast Brazil. This analysis is focused on the interference of the landscape conditions, and its changes, due to the following factors: the oil and natural gas industry, tropical fruits industry, shrimp farms, marine salt industry, occupation of the sensitive areas; demand for land, vegetation degradation, siltation in rivers, severe flooding, sea level rise (SLR), coastal dynamics, low and flat topography, high ecological value and tourism in the region and the rapid growth of urbanization. Conventional and remote sensing data were analyzed using modeling techniques based on ArcGIS, ER-Mapper, ERDAS Imagine and ENVI software. Digital images were initially processed by Principal Component Analysis and transformation of the maximum fraction of noise, and then all bands were normalized to reduce errors caused by bands of different sizes. They were integrated in a Geographic Information System analysis to detect changes, to generate digital elevation models, geomorphic indices and other variables of the study area. A three band color combination of multispectral bands was used to monitor changes of land and vegetation cover from 1986 to 2009. This task also included the analysis of various secondary data, such as field data, socioeconomic data, environmental data and prospects growth. The main objective of this study was to improve our understanding of eco-environmental vulnerability and risk assessment; it´s causes basically show the intensity, its distribution and human-environment effect on the ecosystem, and identify the high and low sensitive areas and area of inundation due to future SLR, and the loss of land due to coastal erosion in the Apodi-Mossoró estuary in order to establish a strategy for sustainable land use. The developed model includes some basic factors such as geology, geomorphology, soils, land use / land cover, vegetation cover, slope, topography and hydrology. The numerical results indicate that 9.86% of total study area was under very high vulnerability, 29.12% high vulnerability, 52.90% moderate vulnerability and 2.23% were in the category of very low vulnerability. The analysis indicates that 216.1 km² and 362.8 km² area flooded on 1m and 10m in sea levels respectively. The sectors most affected were residential, industrial and recreational areas, agricultural land, and ecosystems of high environmental sensitivity. The results showed that changes in eco-environmental vulnerability have a significant impact on the sustainable development of the RN state, since the indicator is a function of sensitivity, exposure and status in relation to a level of damage. The model were presented as a tool to assist in indexing vulnerability in order to optimize actions and assess the implications of decisions makers and policies regarding the management of coastal and estuarine areas. In this context aspects such as population growth, degradation of vegetation, land use / land cover, amount and type of industrialization, SLR and government policies for environmental protection were considered the main factors that affect the eco-environmental changes over the last three decades in the Apodi-Mossoró estuary.
