We presented an application of the Lattice Boltzmann method (LBM) to study the dynamics of Min proteins oscillations in Escherichia coli. The oscillations involve MinC, MinD and MinE proteins, which are required for proper placement of the division septum in the middle of a bacterial cell. Here, the LBM is applied to a set of the deterministic reaction diffusion equations which describes the dy...

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 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...

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 recent years, the lattice Boltzmann equation has developed into a promising technique for computational fluid dynamics (CFD). The model (LBM) approach is derived from and kinetic theory, as opposed to standard CFD methods that are based on direct discretization of Navier–Stokes equations. this paper, Newtonian flow passing through wavy walled channel been examined laminar turbulent transitio...

Homogeneity is of utmost importance in some applications light-burnt magnesia (LBM), such as shrinkage compensation cement composites, because if it not detected reliably before application, causes unpredicted expansion and cracking. This paper presents an accelerated method for homogeneity thermal history detection LBM. The proposed provides equation computing the weighted mesopore probability...

Xanthoria parietina mycobiont was isolated and cultured under axenic conditions. The development of the fungi in aposymbiotic culture depended on the carbon source present in the nutritive medium. The highest development was obtained with 4% glucose in LBM. Nevertheless, the major yield of spore germination was in BBM medium. When the sporulation process was carried out in LBM (without contamin...
