We have examined the responses of energy and protein metabolism to nutrient intake in nine patients with lung carcinoma, of whom none »ere cachexie and only one had distant métastases,compared with nine control patients for elective aneurism surgery, who were comparable in terms of age, body mass index, and smoking habits. Whole-body protein turnover and leucine oxidation were assessed by pri...

BACKGROUND No single measurement adequately defines protein-energy malnutrition. In the dialysis population, somatic protein mass, a useful marker of protein malnutrition, is estimated using the creatinine index (CI), lean body mass (LBM) or both, but the clinical usefulness of these indices remains uncertain. Moreover, calculating these indices requires formal creatinine kinetics or urine and ...

The calculation of wind load high-rise buildings depends on the pressure distribution data and coefficient outer surface building, but actual measurement is difficult to carry out. In order obtain effective building application extended lattice Boltzmann method (LBM) in resistance buildings, this paper, wall-adapting local eddy (WALE) model, dynamic Smagorinsky model (DSM), (SM) are embedded in...

The lattice Boltzmann method (LBM) is a valuable numerical tool in musical acoustics, particularly when modeling wind instruments for which the interaction between the flow and the acoustic field is important. This paper describes an approach for addressing two limitations of LBM, namely computational cost and the inability to directly impose acoustical boundary conditions at open boundaries. T...

In this paper, we use a lattice Boltzmann model (LBM) for simulation of rarefied gas flows in microchannels at high and moderate Knudsen numbers. The lattice Boltzmann method uses D2Q9 lattice structure and BGK collision operator with single relaxation time. The solid wall boundary conditions used in this paper are based on the idea of bounceback of the nonequilibrium part of particle distribut...

Background: This study was aimed to evaluate the effects of physical exercise on bone mineral density (BMD), lean body mass (LBM) and bone biomarkers in children with acute lymphoblastic leukemia on chemotherapy. Methods: forty-six leukemic children were randomly assigned to two groups; exercise group (E) undergoing supervised mixed exercise program consisting of aerobic, resistance and flexib...

In incisive and well-informed papers Herrigel and Whitford and Zeitlin defend the pragmatic collaborations/learning-by-monitoring (PC or LBM) view of customer– supplier relations against rival interpretations, but point to defects in the argument that may be related to fundamental limitations in the whole approach. Herrigel argues that whereas LBM suggests that customer–supplier relations will ...

In this paper, we consider the implementation of a thermal flow solver based on the lattice Boltzmann method (LBM) for graphics processing units (GPU). We first describe the hybrid thermal LBM model implemented, and give a concise review of the CUDA technology. The specific issues that arise with LBM on GPUs are outlined. We propose an approach for efficient handling of the thermal part. Perfor...

The lattice Boltzmann method (LBM) for computational fluid dynamics benefits from a simple, explicit, completely local computational algorithm making it highly efficient. We extend LBM to recover hydrodynamics of multi-component immiscible fluids, while retaining a completely local, explicit and simple algorithm. Hence, no computationally expensive lattice gradients, interaction potentials or c...
