Comparação do Gasto energético de repouso obtido pela calorimetria indireta com as equações de predição em pacientes idosos em tratamento crônico de hemodiálise

Assim como na população geral, as necessidades energéticas diárias dos pacientes em tratamento crônico de hemodiálise (HD) podem ser calculadas multiplicando-se o gasto energético de repouso (GER) pelo nível de atividade física. Até o momento, não há estudos que avaliaram se as equações de predição são precisas para se estimar o GER de idosos em HD. O objetivo do presente estudo foi avaliar a concordância entre o GER obtido pela calorimetria indireta e as equações de predição de Harris&Benedict, Schofield e a proposta pelo documento da Organização Mundial de Saúde de 1985 (FAO 1985) nos pacientes idosos em HD. Tratou-se de um estudo transversal, onde foi avaliado o GER de 57 pacientes idosos não institucionalizados (> 60anos) em tratamento crônico de HD mensurado pela calorimetria indireta e comparado com as equações de predição de Harris&Benedict, Schofield e FAO 1985.A concordância entre o GER medido e as equações foi realizada pelo coeficiente de correlação intraclasse e pela análise de Bland-Altman. Neste estudo pode-se observar que o GER estimado pelas 3 equações foi significantemente maior do que o obtido pela calorimetria indireta. Um grau de reprodutibilidade moderado foi observado entre a calorimetria indireta e as equações. A superestimação foi o principal erro observado, sendo presente na metade dos pacientes. A subestimação foi vista em aproximadamente em 10 % dos pacientes. Com base nesses achados podemos concluir que as 3 equações tiveram uma performance similar ao estimar o GER. E estas podem ser utilizadas para calcular o GER de idosos em HD, na medida em que os nutricionistas reconheçam seus possíveis erros, principalmente quando as equações de predição subestimam o GER medido.

Entre a Oração e o Trabalho: o estudo da Psicologia no Mosteiro de São Bento do Rio de Janeiro entre 1930 e 1950

Esta tese tem por objetivo apontar como a psicologia se torna uma ferramenta importante na formação do clero, especificamente, seu ensino no seminário de formação religiosa católica do Mosteiro de São Bento do Rio de Janeiro, no período de 1930 a 1950. Os religiosos católicos fizeram parte de muitos acontecimentos não só da história da Igreja, mas também da própria história do Brasil. Comandaram a educação nos primórdios da colonização, mantendo influência na organização educacional mesmo com a proclamação da República como estado laico. Falar da formação do homem/sacerdote decorre do entendimento de que os religiosos católicos foram um dos principais grupos disseminadores do saber psicológico em nossa pátria. O período de nosso recorte é marcado por transformações na política, na economia e na educação nacional que afetaram a todos, inclusive ao clero. Entre as mudanças no seminário de São Bento, encontramos a introdução da disciplina psicologia no currículo de formação dos monges, bem como a presença de uma crescente literatura psicológica introduzida principalmente através de comentadores religiosos, demonstrando que as relações entre Igreja e ciência assumem novo patamar no período estudado

Energy analysis of the ring seine operations, off Cochin, Kerala

Ring seines are lightly constructed purse seines adapted for operation in the traditional sector. Fish production and energy requirement in the ring seine operations, off Cochin, Kerala, India are discussed in this paper, based on data collected during 1997- 1998. The results reflect the Gross Energy Requirement (GER) situation that existed during 1997-1998. Mean catch per ring seiner per year worked out to be 211.9 t of which sardines (Sardinella spp.) constituted 44.3%, followed by Indian mackerel (Rastrelliger kanagurta) 29.7%, carangids 11.4%, penaeid prawns 2.2%, pomfrets 1.1% and miscellaneous fish 11.3%. Total energy inputs into the ring seine operations were estimated to be 1300.8 GJ. Output by way of fish production was determined to be 931.85 GJ. GER is the sum of all non-renewable energy resources consumed in making available a product or service and is a measure of intensity of non-renewable resource use. GER per tonne of fish landed by ring seiners was estimated to be 6.14. Among the operational inputs, kerosene constituted 73.4% of the GER, followed by petrol (12.7%), diesel (6.7%) and lubricating oil (2.4%). Fishing gear contributed 3.8%, engine 0.8% and fishing craft 0.3% of the GER. Energy ratio for ring seining was 0.72 and energy intensity 1.40.

Precious Corals in Hawaii: Discovery of a New Bed and Revised Management Measures for Existing Beds

The fishery for deepwater precious corals in the Hawaiian Islands has experienced an on-and-off history for almost 40 years. In spite of this, research, driven primarily by the precious coral jewelry industry, remains active. In this paper, the results of deepwater surveys in 2000 and 2001 are reported. In summary, a new bed on the summit of Cross Seamount is described and revised estimates of MSY’s for pink coral, Corallium secundum; red coral, Corallium regale; and gold coral, Ger ardia sp., in the two known beds off Makapuu, Oahu, and Keahole Point, Hawaii, in the main Hawaiian Islands, are presented. The population dynamics of each species is described, as well as their ecological limits on Hawaii’s deep reefs, island shelves, and seamounts. The local supply of precious coral in the main Hawaiian Islands is sufficient to support the local industry, but cost/ benefits of selective harvest requirements and weather constraints limit profitability of the fish

Gross energy requirement in fishing operations

Energy is a key input into the fish harvesting process. Efficient use of energy helps in reducing operational costs and environmental impact, while increasing profits. Energy optimisation is an important aspect of responsible fishing as enunciated in the Code of Conduct for Responsible Fisheries. Gross Energy Requirement (GER) is the sum of all non-renewable energy resources consumed in making available a product or service and is expressed in energy units per physical unit of product or service delivered. GER is a measure of intensity of non-renewable resource use and it reflects the amount of depletion of earth’s inherited store of non-renewable energy in order to create and make available a product or service. In this study, GER in fish harvesting up to the point of landing is estimated in selected fish harvesting systems in the small-mechanised sectors of Indian fisheries and compared with reported results from selected non mechanised and motorised fishing systems to reflect the situation during 1997-1998. Among the fish harvesting systems studied, GER t fish-1 ranged from 5.54 and 5.91 GJ, respectively, for wooden and steel purse seiners powered by 156 hp engines; 6.40 GJ for wooden purse seiner with 235 hp engine; 25.18 GJ for mechanised gillnet/line fishing vessel with 89 hp engines; to 31.40 and 36.97 GJ, respectively, for wooden and steel trawlers powered by 99-106 hp engines.

Luminescence properties of Eu(phen)(2)Cl-3 doped in sol-gel-derived SiO2-PEG matrix

Rare earth complex Eu(phen)(2)Cl-3 was introduced into a SiO2-PEG-400 hybrid material by a sol-ger method. The result indicated that Poly(ethylene glycol) (PEG) could associate with Eu3+ and change the surroundings of Eu3+ in the hybrid material, greatly improving the decay time. Transparent SiO2-PEG400 hybrid doped with a very small amount of Eu(phen)(2)Cl-3 has better mechanical properties and can retain excellent luminescence properties of the rare earth complex.

What serious game studios want from ICT research: identifying developers’ needs

Although many scholars recognise the great potential of games for teaching and learning, the EU-based industry for such “serious” games” is highly fragmented and its growth figures remain well behind those of the leisure game market. Serious gaming has been designated as a priority area by the European Commission in its Horizon 2020 Framework Programme for Research and Innovation. The RAGE project, which is funded as part of the Horizon 2020 Programme, is a technology-driven research and innovation project that will make available a series of self-contained gaming software modules that support game studios in the development of serious games. As game studios are a critical factor in the uptake of serious games, the RAGE projects will base its work on their views and needs as to achieve maximum impact. This paper presents the results of a survey among European game studios about their development related needs and expectations. The survey is aimed at identifying a baseline reference for successfully supporting game studios with advanced ICTs for serious games.

Phytoplankton phenology indices in coral reef ecosystems: Application to ocean-color observations in the Red Sea

Phytoplankton, at the base of the marine food web, represent a fundamental food source in coral reef ecosystems. The timing (phenology) and magnitude of the phytoplankton biomass are major determinants of trophic interactions. The Red Sea is one of the warmest and most saline basins in the world, characterized by an arid tropical climate regulated by the monsoon. These extreme conditions are particularly challenging for marine life. Phytoplankton phenological indices provide objective and quantitative metrics to characterize phytoplank- ton seasonality. The indices i.e. timings of initiation, peak, termination and duration are estimated here using 15 years (1997–2012) of remote sensing ocean-color data from the European Space Agency (ESA) Climate Change Initiative project (OC-CCI) in the entire Red Sea basin. The OC-CCI product, comprising merged and bias-corrected observations from three independent ocean-color sensors (SeaWiFS, MODIS and MERIS), and processed using the POLYMER algorithm (MERIS period), shows a significant increase in chlorophyll data cover- age, especially in the southern Red Sea during the months of summer NW monsoon. In open and reef-bound coastal waters, the performance of OC-CCI chlorophyll data is shown to be comparable with the performance of other standard chlorophyll products for the global oceans. These features have permitted us to investigate phytoplankton phenology in the entire Red Sea basin, and during both winter SE monsoon and summer NW monsoon periods. The phenological indices are estimated in the four open water provinces of the basin, and further examined at six coral reef complexes of particular socio-economic importance in the Red Sea, including Siyal Islands, Sharm El Sheikh, Al Wajh bank, Thuwal reefs, Al Lith reefs and Farasan Islands. Most of the open and deeper waters of the basin show an apparent higher chlorophyll concentration and longer duration of phyto- plankton growth during the winter period (relative to the summer phytoplankton growth period). In contrast, most of the reef-bound coastal waters display equal or higher peak chlorophyll concentrations and equal or lon- ger duration of phytoplankton growth during the summer period (relative to the winter phytoplankton growth period). The ecological and biological significance of the phytoplankton seasonal characteristics are discussed in context of ecosystem state assessment, and particularly to support further understanding of the structure and functioning of coral reef ecosystems in the Red Sea.
