Finite deformation theory of hierarchically arranged porous solids—I. Balance of mass and momentum
Условия формирования зон скопления метана в углепородном массиве
Розглянуті основні геологічні чинники, які впливають на формування зон скупчення метану у вуглепородному масиві. Виділені, найбільш ефективні показники для середнього катагенеза порід – опосередковані локальні структури, зони тріщинуватості порід, стрижневі ділянки пісковиків (палеопотоки). Для виділених показників виконаний розрахунок дисперсійного аналізу по альтернативній ознаці. На основі розрахунків встановлено вплив кожного фактора на формування зон скупчення метану у вуглепродному масиві.Basic geological factors, which influence on forming of zone of accumulation of methane in coalrock massif, are presented. The most effective indexes for middle katagenesis of rock are determinated - medial local structures, zone of jointing of rock, race areas of sandstones (paleocurrent). For determinated indexes calculation of dispersion on an alternative character is executed. On the basis of calculations influence of every factor on forming of zone of accumulation of methane in a coalrock massif is definited

Cardiac mechanoenergetics replicated by cross-bridge model. Ann Biomed Eng 28: 629–640
Abstract-The aim of this work is to reproduce the experimentally measured linear dependence of cardiac muscle oxygen consumption on stress-strain area using a model, composed of a three-state Huxley-type model for cross-bridge interaction and a phenomenological model of Ca 2ϩ -induced activation. By selecting particular cross-bridge cycling rate constants and modifying the cross-bridge activation model, we replicated the linear dependence between oxygen consumption and stressstrain area together with other important mechanical properties of cardiac muscle such as developed stress dependence on the sarcomere length and force-velocity relationship. The model predicts that ͑1͒ the amount of the ''passenger'' cross bridges, i.e., cross bridges that detach without hydrolyzing ATP molecule, is relatively small and ͑2͒ ATP consumption rate profile within a beat and the amount of the passenger cross bridges depend on the contraction protocol. © 2000 Biomedical Engineering Society. ͓S0090-6964͑00͒00206-X
