Ontario Paper Company Limited

On February 29, 1912 The Ontario Paper Company Limited was incorporated under the leadership of Col. Robert R. McCormick. Four months later construction began in Thorold, Ontario as this location was best for the abundance of power and water and water transportation. The first machine was started at the mill on September 5, 1913. The mill was one of the most advanced of its era, using electricity instead of water power. The mill was also the first of its kind as it combined pulp and paper making instead of separating the two operations.

Past, present and future precipitation in the Middle East: insights from models and observations

Anthropogenic changes in precipitation pose a serious threat to society—particularly in regions such as the Middle East that already face serious water shortages. However, climate model projections of regional precipitation remain highly uncertain. Moreover, standard resolution climate models have particular difficulty representing precipitation in the Middle East, which is modulated by complex topography, inland water bodies and proximity to the Mediterranean Sea. Here we compare precipitation changes over the twenty-first century against both millennial variability during the Holocene and interannual variability in the present day. In order to assess the climate model and to make consistent comparisons, this study uses new regional climate model simulations of the past, present and future in conjunction with proxy and historical observations. We show that the pattern of precipitation change within Europe and the Middle East projected by the end of the twenty-first century has some similarities to that which occurred during the Holocene. In both cases, a poleward shift of the North Atlantic storm track and a weakening of the Mediterranean storm track appear to cause decreased winter rainfall in southern Europe and the Middle East and increased rainfall further north. In contrast, on an interannual time scale, anomalously dry seasons in the Middle East are associated with a strengthening and focusing of the storm track in the north Mediterranean and hence wet conditions throughout southern Europe.

Habitat associations and breeding bird community composition within the city of Bristol, UK

Capsule: Different urban breeding bird communities are associated with different habitat types, but, although community species diversity varies significantly, total bird density does not. Aims: To investigate the association between breeding bird communities and habitats within Bristol, UK and how these communities vary in terms of species diversity and total bird abundance. Methods: Breeding density data for 70 species in the metropolitan area of Bristol, UK were subjected to de-trended correspondence analysis to identify the number of different communities present and their indicator species. These data were then used to identify patterns of habitat association with each community and differences in species richness and total bird density. Results: Three communities were identified: a rural community associated with woodland, managed grassland and inland water; a suburban community associated with buildings and residential gardens; and an intermediate community that shared some of these habitat characteristics. Species richness, but not total bird abundance, was lowest in the suburban community. Conclusion: The diversity of species in urban areas appears to be most dependent upon the availability of patches of natural and semi-natural habitats. Residential gardens support fewer species, but those species that are present may be found at high densities.

The compositional and configurational heterogeneity of matrix habitats shape woodland carabid communities in wooded-agricultural landscapes

Landscape heterogeneity (the composition and configuration of matrix habitats) plays a major role in shaping species communities in wooded-agricultural landscapes. However, few studies consider the influence of different types of semi-natural and linear habitats in the matrix, despite their known ecological value for biodiversity. Objective To investigate the importance of the composition and configuration of matrix habitats for woodland carabid communities and identify whether specific landscape features can help to maintain long-term populations in wooded-agricultural environments. Methods Carabids were sampled from woodlands in 36 tetrads of 4 km2 across southern Britain. Landscape heterogeneity including an innovative representation of linear habitats was quantified for each tetrad. Carabid community response was analysed using ordination methods combined with variation partitioning and additional response trait analyses. Results Woodland carabid community response was trait-specific and better explained by simultaneously considering the composition and configuration of matrix habitats. Semi-natural and linear features provided significant refuge habitat and functional connectivity. Mature hedgerows were essential for slow-dispersing carabids in fragmented landscapes. Species commonly associated with heathland were correlated with inland water and woodland patches despite widespread heathland conversion to agricultural land, suggesting that species may persist for some decades when elements representative of the original habitat are retained following landscape modification. Conclusions Semi-natural and linear habitats have high biodiversity value. Landowners should identify features that can provide additional resources or functional connectivity for species relative to other habitat types in the landscape matrix. Agri-environment options should consider landscape heterogeneity to identify the most efficacious changes for biodiversity.

Aspectos fisiológicos e bioquímicos de cultivares de soja submetidos a déficit hídrico induzido por peg 6000

In soybean culture water deficit is one of the most limiting factors to the maximum yield obtained. Genotypes identification with drought tolerance capacity is fundamental to solve this problem. The objective in this paper was analyze the physiological quality and physiological and biochemical responses of soybeans cultivars (MG/BR 46 Conquista, UFUS Carajás, UFUS Impacta, UFUS Riqueza and UFUS Xavante) submitted to water stress with PEG 6000 solutions in different levels of osmotic potentials (0; -0,1; -0,2; -0,3 and -0,4 MPa). Physiological quality of cultivars were evaluated by seedling length test and fresh and dry biomass. The biochemical responses were evaluated by detection of indol-acetic acid (IAA), by saccharose content and seedling water transportation. UFUS Riqueza presented the best performance in physiological quality tests, saccharose content, absorption and water absorption velocity in seedling. UFUS Xavante showed the highest IAA's concentration and the greater weight of seedling in water transportation test.

Análise dos circuitos de produção, reprodução e subsistência do transporte hidroviário de passageiros nas ilhas da Região Metropolitana de Belém: uma contribuição para a revitalização do setor

O objetivo desta pesquisa é descrever e analisar a funcionalidade do sistema de transporte hidroviário de passageiros nas ilhas da Região Metropolitana de Belém (RMB). Buscou-se uma construção teórica baseada, principalmente, nas abordagens de Milton Santos, Pierre Bourdieu, Associação Nacional de Transportes Públicos e Eduardo Vasconcellos. A partir desse referencial a tese explica que as condições de transporte hidroviário em geral estão relacionadas com teorias de divisão do espaço onde o poder de consumo e renda é o que determina a integração espacial do indivíduo. E que, portanto, o serviço de transporte nas ilhas da RMB, operado pela lógica do mercado, exclui espacialmente quem não tem esse poder. O conhecimento dessa realidade foi baseado em pesquisa de campo em 20 ilhas da RMB. Utilizaram-se as técnicas de observação e entrevista para explicar a dinâmica dos deslocamentos dos ribeirinhos, identificando circuitos de produção, reprodução e subsistência. Os primeiros assemelham-se com a teoria de Milton Santos de circuito superior, representado por Belém, e inferior, representado pelas ilhas. O circuito de subsistência nasce dentro do circuito inferior a partir da forte relação que existe entre as próprias ilhas, sendo uma estratégia de deslocamento dos ribeirinhos para receber auxílios básicos de saúde, educação e transportes. Utilizou-se a análise fatorial para obter um ranking das ilhas segundo as condições de transporte e a análise de regressão para explicar que a demanda por viagens nas ilhas aumenta, basicamente, quando a renda e a população aumentam. As propostas para revitalização do setor do transporte hidroviário resultou na identificação de novas rotas de transporte e melhorias na infraestrutura de trapiches e embarcações.

Ferramenta de avaliação do transporte hidroviário de passageiros da região amazônica

A Amazônia brasileira detém mais de 60% da água doce disponível no Brasil, por onde passa um dos maiores rios do mundo, o Rio Amazonas, tanto em extensão como em volume de água, além de abrigar uma das maiores redes hidroviárias do Planeta, com centenas de rios caudalosos. É nesse sistema que a presente pesquisa se propôs a fazer uma análise quantitativa e qualitativa da frota de embarcações, terminais e demanda de passageiros que são transportados pelos rios da Amazônia brasileira, visando contribuir para o desenvolvimento tecnológico do transporte hidroviário de passageiros na região. Através de um método matemático para o cálculo do valor da tarifa por passageiro, que leva em consideração as características físicas e operacionais de cada linha, buscou-se analisar os valores praticados, assim como otimizou-se os parâmetros de uma embarcação com as condições ideais e de menor custo por passageiro transportado. Neste aspecto verificou-se ainda, que o custo do transporte do passageiro pode ser reduzido com um projeto de embarcação mais adequado para cada linha e respectiva demanda. Os dados, informações e previsões sobre a produção do transporte hidroviário de passageiros são apresentados para melhor entendimento do setor de maneira a possibilitar propostas de transportes mais eficientes, de acordo com as características da via navegável e do ambiente operacional. Com o método de avaliação de custo proposto foi possível verificar que o custo do transporte hidroviário de passageiro na Amazônia não é homogêneo, em virtude da grande diversidade de embarcações que operam em cada linha, e que, a otimização do projeto adequado para cada linha pode ter grande reduções no custo do passageiro transportado.
