The Rayleigh-Bénard theory by Grossmann and Lohse [J. Fluid Mech. 407, 27 (2000)] is extended towards very large Prandtl numbers Pr. The Nusselt number Nu is found here to be independent of Pr. However, for fixed Rayleigh numbers Ra a maximum in the Nu(Pr) dependence is predicted. We moreover offer the full functional dependences of Nu(Ra,Pr) and Re(Ra,Pr) within this extended theory, rather th...

  This paper presents a modeling study of a CNG Homogenous Charge Compression Ignition (HCCI) engine using single-zone and multi-zone combustion models. Authors' developed code could be able to predict engine combustion and performance parameters in closed part of the engine cycle. As detailed chemical kinetics is necessary to investigate combustion process in HCCI engines, therefore, GRI-m...

Our summary of the work of Keller and Niordson (J. Math. Mech. 16, pp. 433–446, 1966) was inaccurate. We offer a correction.

Abstract “Mechanization” is a procedure of replacing scalar field in 1+1 dimensions with piecewise linear function, i.e. finite graph consisting N joints (vertices) and straight segments (edges). As result, the theory approximated by sequence algebraically tractable, general-purpose collective coordinate mechanical models. We observe step-by-step emergence dynamical objects associated phenomena...

This study was designed to characterize the endothelium-dependent contracting factor (EDCF) released by arachidonic acid (AA) and methacholine (MeCH) in the rabbit pulmonary artery. AA and MeCH contract the rabbit pulmonary artery; however, the effects of both are blocked by denuding the vessels and by administration of indomethacin (a cyclooxygenase inhibitor), dazoxiben (a thromboxane [TX] sy...

BACKGROUND Mechlorethamine [ClCH(2)CH(2)N(CH(3))CH(2)CH(2)Cl], a nitrogen mustard alkylating agent, has been proven to form a DNA interstrand crosslink at a cytosine-cytosine (C-C) mismatch pair using gel electrophoresis. However, the atomic connectivity of this unusual crosslink is unknown. METHODOLOGY/PRINCIPAL FINDINGS HPLC-UV, MALDI-TOF-MS, and ESI-MS/MS were used to determine the atomic ...

The displacement of a more viscous fluid by a miscible, less viscous one of lower density in a horizontal capillary tube is studied by means of Stokes flow simulations. Both axisymmetric and three-dimensional simulations are conducted at Péclet numbers up to 104, in order to resolve discrepancies between earlier simulations by [C.Y. Chen, E. Meiburg, Miscible displacements in capillary tubes. P...

The central philosophy of statistical mechanics (stat-mech) and random-matrix theory complex systems are that while individual instances essentially intractable to simulate, the properties random ensembles obey simple universal “laws.” This same promises powerful methods for studying dynamics quantum information in ideal noisy circuits—for which classical description circuits is expected be gen...

A reanalysis of existing data suggests that the established tenet of increasing efficiency of transport with body size in terrestrial locomotion requires re-evaluation. Here, the statistical model that described the data best indicated a dichotomy between the data for small (<1 kg) and large animals (>1 kg). Within and between these two size groups there was no detectable difference in the scal...
