Particle-Imaging Techniques for Experimental Fluid Mechanics

, 1991
An important achievement of modern experimental fluid mechanics is the invention and development of techniques for the measurement of whole, instantaneous fields of scalars and vectors. These techniques include tomographic interferometry (Hesselink 1988)

UFF, a full periodic table force field for molecular mechanics and molecular dynamics simulations

, 1992
A new molecular mechanics force field, the Universal force field (UFF), is described wherein the force field parameters are estimated using general rules based only on the element, its hybridization, and its connectivity. The force field functional forms,

Mechanisms and Mechanical Philosophy

2015
The past twenty years have seen a resurgence of philosophical interest in mechanisms, an interest that has been driven both by concerns with the logical empiricist tradition and by the sense that a philosophy of science that attends to mechanisms will be more successful than traditional alternatives in illuminating the actual content and practice of ...

Molecular mechanisms of cellular mechanics

Physical Chemistry Chemical Physics, 2006
Mechanical forces play an essential role in cellular processes as input, output, and signals. Various protein complexes in the cell are designed to handle, transform and use such forces. For instance, proteins of muscle and the extracellular matrix can withstand considerable stretching forces, hearing-related and mechanosensory proteins can transform ...

Mechanisms of Mechanical Alloying

1998
Unlike conventional processes in which materials are produced either by melting or sintering at high temperature, synthesis of different types of materials using the mechanical alloying or milling process is generally carried our at room temperature although temperature may rise during milling.

Mechanics without mechanisms

Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics, 2018
Abstract At the time of Heinrich Hertz's premature death in 1894, he was regarded as one of the leading scientists of his generation. However, the posthumous publication of his treatise in the foundations of physics, Principles of Mechanics, presents a curious historical situation. Although Hertz's book was widely praised and admired, it was also met

Mechanisms of hypoxemia

Intensive Care Medicine, 2005
A fundamental aspect of cardiopulmonary homeostasis is the adequate delivery of oxygen to meet the metabolic demands of the body. Cardiac output, O2-carrying capacity (i.e., hemoglobin concentration and quality), and arterial PO2 (PaO2) determine O2 transport.

Mechanism and the mobility of mechanism

2007
Some opening remarks 01. Some successful mechanical devices function smoothly however poorly they are made, while others do this only by virtue of the accurate construction and fitting of their moving parts. In this chapter I try to quantify such phenomena.
