Gangrena de Fournier: experiência de 12 anos

Impact of network physical topology on planning multiband optical networks awar...

A multiband planning tool is developed in this work to solve the routing, modulation format and spectrum as signment problem and is used to discuss the influence of the network physical topology on several parameters considering four optical network topologies, different target bit error rates (BERs) and transmission capacities. We conclude that, in non-regenerated optical links, the length of the network links...

CMS physics technical design report: Addendum on high density QCD with heavy ions

Made available in DSpace on 2022-04-28T20:22:10Z (GMT). No. of bitstreams: 0 Previous issue date: 2007-11-01; This report presents the capabilities of the CMS experiment to explore the rich heavy-ion physics programme offered by the CERN Large Hadron Collider (LHC). The collisions of lead nuclei at energies , will probe quark and gluon matter at unprecedented values of energy density. The prime goal of this res...

Progress in Identifying High Nature Value Montados: Impacts of Grazing on Hardw...

Due to their complex structure and traditional low-intensity management, Portuguese oak woodland rangelands known as montados are often considered high nature value (HNV) farming systems, and as such, they may be deemed eligible for subsidies and incentives by governmental and nongovernmental agencies. Too little is known about how the HNV concept might be applied to conserve complex silvopastoral systems. Thes...

Water as a critical issue for viticulture in southern Europe: sustainability vs...

Water is a vulnerable resource in the Mediterranean region, but irrigation demands have been increasing to mitigate effects of environmental stress. Sustainable wine production involves the precise use of water in the vineyard and winery. Improved knowledge on grapevine ecophysiology and genetics, the use of sensors for soil and canopy monitoring, plant phenotyping and improved crop management can help save wat...

The Influence of Active Workstations on Work Performance, Productivity Indicato...

The most of strategies to promote physical activity in workplaces interfere with work tasks and many organizations declined these programs. The aim of this review is to understand the impact of the active workstations on the performance and productivity indicators, and also on the reduction of the sedentary time. This review applied PRISMA methodology. 389 studies were identified by searching the different data...

Methods of posture analysis for computer workers

Musculoskeletal disorders (MSDs) have been identified as a predisposing factor for lesser productivity and are considered to be a major occupational health problem contributing significantly to absenteeism, disability and loss of productivity. Computer users may develop musculoskeletal disorders due to the forces applied, muscle use, posture and wrist velocity and acceleration exposures during computer use. Wor...

EFEITO DO QUITOSANO E ÁCIDO ACÉTICO NA CONSERVAÇÃO DE UVA DE MESA

Todos os produtos de origem vegetal sofrem perdas de qualidade desde o momento da colheita até ao seu consumo. A utilização de quitosano como revestimento edível tem sido uma alternativa considerada no tratamento pós-colheita de uva de mesa com bons resultados. Tendo em consideração que a preparação de revestimentos à base deste biopolímero é realizada em solução de ácido acético, pretendeu-se avaliar se a apli...

Impact of irrigation in production and oil properties in intensive and hedgerow...
