O presente trabalho tem como objetivo analisar as transformacoes da producao artesanal de redes de dormir, no nordeste brasileiro, e as repercussoes dessas transformacoes onde essa atividade e exercida. Para se atingir tal objetivo, parte-se do pressuposto de que as transformacoes ocorridas decorrem de processos relacionados com a incorporacao de materias-primas industriais e de ampliacao do mercado de consumo, sobretudo quando a rede passa a ser considerada como um bem de lazer e decoracao. Este estudo procura abranger os diferentes segmentos relacionados com essa problematica em algumas cidades nordestinas. Numa pesquisa direta, coletaram-se informacoes sobre as materias-primas, os instrumentos, as tecnicas e as relacoes sociais inerentes a atividade. Este estudo mostra que as transformacoes verificadas abrangem a reorganizacao da producao de redes e o aproveitamento das tecnicas de tecelagem das redes para a producao de outros bens, contribuindo, assim para a reproducao do espaco. / This study has the objective to analyze changes in handcraft of sleeping hammocks in Brazilian Northeast and implications of these transformations upon developed activities. In order to achieve this end, the premise is that occurred changes are caused by processes related to incorporation of industrial raw materials and expansion of consumption market, mainly when hammock becomes a leisure and decorative article. This research covers different segments related to this problem in some northeast cities. On direct research, it was collected information about raw material, instruments, techniques and social relations inherent to the activity. This study demonstrates that verified changes comprises reorganization of hammock production and utilization of hammock weaving techniques on other goods manufacturing and so contributing space reproduction.

Spatial and temporal heterogeneity of water and nutrient pools is closely associated with the existence of different plant communities in hydrologically-controlled ecosystems such as the Everglades. These various communities differ in their flooding and fire tolerances as well as nutrient requirements. Upland plant communities are of particular ecological significance since they have high biodiversity and provide habitat to terrestrial fauna, yet comprise less than 10 % of the total area. Restoration and maintenance of such communities requires an understanding of their water and nutrient requirements. Chapter 2 compares water source utilization in hammocks and pine rocklands on the Miami Rock Ridge using stable isotopes of water. Hammocks do not flood, while adjacent pinelands may flood between 2-3 months. In the wet season, hammocks were found to use phosphorus (P) rich soilwater, a local pool of water and nutrients while pineland plants primarily relied upon groundwater, the regional pool. Access to a rich pool of P in the oligotrophic Everglades was associated with higher community-level foliar P concentration in hammocks. However in the dry season, hammocks utilized groundwater, which suggests sensitivity to extended droughts. Chapter 3 compares the hammock (upland or head) and swamp forests (lowland or tail) on tree islands in the Shark River Slough. Uplands were associated with P-rich soilwater uptake in the wet season, with regional water uptake in the dry season. Accordingly, tree island heads are rich in foliar P and thereby P-hotspots in the Everglades. Foliar nutrient concentrations can thus indicate limiting nutrient availability in the Everglades. Chapter 4 looks at how leaf phenology patterns are tied to water and nutrient pools. Leaf fall in ridge hammocks is associated with high foliar carbon isotope values over the dry season, which is not the case for tree island hammocks. However, in some species, high levels of foliar nitrogen are also associated with high foliar C13 values indicating stomatal limitation of photosynthesis. Growing season for most hammock species is the wet season coinciding with high availability of P, as reflected in high foliar P in this season. Linking water sources to foliar nutrients elucidates roles of water and nutrient pools in leading to different plant communities within an ecosystem.

We construct a category of short hammocks and show that it has the weak homotopy type of mapping spaces. In doing so we tackle the problem of applying the nerve to large categories without the use of multiple universes. We also explore what the mapping space is. The main tool in showing the connection between hammocks and mapping spaces will be the use of homotopy groupoids, homotopy groupoid actions and the homotopy fiber of their corresponding bar constructions. / <p>QC 20141208</p>

On this context, for this work, we collected water and sediment samples at three different points of the Piranhas, with the objective to evaluate a possible contamination of these compartments resulting from dumping of textile effluent. Were also determined the variables Dissolved Oxygen (DO), Total Dissolved Solids (TDS), OM (Organic Matter), Conductivity, pH and temperature. The results obtained for these parameters are consistent with those expected for the location of the environment under study, where the rainfall is marked by extreme irregularity. An analysis screening using the voltammetry technique was used to indicate the presence of trace metals in water, this analysis showed the possible presence of metals, Zn, Pb and Cu. Concerning the sediment samples, the quantitative analysis performed using the technique of ICP-MS (Inductively Coupled Plasma-Mass Spectrometry) showed that among the investigated metals, Cd, Pb, Cu, Cr, Ni, Cr and Ni elements were those with higher levels during the study period. Using parameters of the sediment quality evaluators, it was observed that the metals Cr and Ni had values that exceeded the lower limit TEL (Canadian guideline value) thus indicating a deleterious made occasional on aquatic biota of the environment under study. Principal components analysis (PCA) using variables such as the physical-chemical parameters and concentrations of metals investigated, highlighted the influence of parameters and STD Conductivity, pH and organic matter in the grouping of data and also showed that the differences in metal contents between months in the study (rainy and dry) were more relevant than the differences between the sampling sites investigated. From the results and taking into account the variables measured along the river, it was found that there is no evidence that the textile wastewater at the moment, is affecting the characteristics of the Piranhas. / Devido à intensa atividade no ramo têxtil o Rio Piranhas, que atravessa o município de São Bento- PB, está servindo como esgotamento para os resíduos gerados nas etapas de branqueamento e tingimento dos fios, uma vez que as redes são fabricadas de maneira artesanal, muitas delas nos quintais das residências. Neste contexto, para este trabalho, foram coletadas amostras de água e sedimento em três pontos distintos do Rio Piranhas, com o objetivo de avaliar uma possível contaminação desses compartimentos resultante do despejo do efluente têxtil. Também foram determinadas os parâmetros físico-químicos oxigênio dissolvido (O.D), sólidos totais dissolvidos (STD), matéria orgânica (M.O), condutividade, pH e temperatura. Os resultados obtidos para estes parâmetros estão de acordo com os esperados para a localização do ambiente em estudo, onde o regime pluviométrico é marcado por extrema irregularidade. Uma análise qualitativa utilizando a técnica de voltametria foi realizada para indicar a presença de metais traço na água, essa análise mostrou a possível presença dos metais Zn, Pb e Cu. Em relação às amostras de sedimento, a análise quantitativa realizada através da técnica de espectrometria de massa com plasma indutivamente acoplado (ICP-MS), mostrou que dentre os metais investigados, Cd, Pb, Cu, Cr e Ni, o Cr e o Ni foram os que apresentaram maiores teores ao longo do período em estudo. Utilizando indicadores estatísticos de qualidade do sedimento, foi observado que Cr e Ni apresentaram valores que ultrapassaram o limite inferior TEL (valor guia canadense) indicando assim, um efeito deletério ocasional sobre a biota aquática do ambiente em estudo. Análises de componentes principais (PCA) utilizando como variáveis os parâmetros físico-químicos e as concentrações dos metais investigados, ressaltou a influência dos parâmetros STD e condutividade, M.O e pH no agrupamento dos dados e mostrou ainda que, as diferenças nos teores de metais entre os meses em estudo (período chuvoso e de seca) foram mais relevantes do que as diferenças entre os pontos de coleta investigados. A partir dos resultados e levando-se em conta os parâmetros medidos no trecho do rio, verificou-se que não há evidência de que o efluente têxtil até o presente momento, esteja afetando as características do Rio Piranhas.

Осанка – привычное положение туловища в пространстве, поза, обусловленная конституционными, наследственными факторами, зависящая от тонуса мышц, состояния связочного аппарата, выраженности физиологических изгибов позвоночника. По данным мировой статистики 34-50% детей имеют разную степень нарушений осанки, а по данным ВОЗ – 80% детей и подростков имеют низкий уровень физической активности. Целью данной работы было разработать и оценить влияния программы физической реабилитации, с использованием йоги в гамаках, на степень выраженности нарушений осанки у детей младшего школьного возраста. В исследовании приняло участие 20 детей с такими нарушениями осанки как: плоская спина, плоско-вогнутая спина, сутулость, круглая спина. В качестве методов исследования степени выраженности нарушений осанки использовались: визуальный осмотр – асимметрия треугольников талии, высоты плеч и лопаток, измерение глубины шейного и поясничного лордозов, и вычисление плечевого индекса; функциональные тесты – силовая выносливость мышц спины и пресса, тест на определение подвижности позвоночника; динамометрия и координационный тест. Согласно полученным результатам, предложенная программа позволила снизить степень выраженности нарушений осанки и улучшить физическую подготовленность детей с нарушениями осанки. Так же результаты позволили подтвердить, что нарушения осанки у детей младшего дошкольного возраста поддаются физической реабилитации с использованием йоги в гамаках и могут успешно корректироваться данным методом. / Posture is the habitual position of the body in space, a posture determined by constitutional, hereditary factors, depending on muscle tone, the state of the ligamentous apparatus, and the severity of the physiological curves of the spine. According to world statistics, 34-50% of children have varying degrees of posture disorders, and according to WHO, 80% of children and adolescents have a low level of physical activity. The purpose of this work was to develop and evaluate the effects of a physical rehabilitation program using yoga in hammocks on the severity of posture disorders in children of primary school age. The study involved 20 children with such posture disorders as: flat back, flat-concave back, stoop, round back. As methods for studying the severity of postural disorders, the following were used: visual examination - asymmetry of the triangles of the waist, the height of the shoulders and shoulder blades, measuring the depth of the cervical and lumbar lordosis, and calculating the shoulder index; functional tests - strength endurance of the muscles of the back and press, a test to determine the mobility of the spine; dynamometry and coordination test. According to the results obtained, the proposed program allowed to reduce the severity of posture disorders and improve the physical fitness of children with posture disorders. The results also confirmed that posture disorders in children of primary preschool age are amenable to physical rehabilitation using yoga in hammocks and can be successfully corrected by this method.
