Analysis of the mechanism of lipoprotein(a) assembly

Clinical Genetics, 1997
We have assessed the ability of a battery of purified recombinant apolipoprotein(a) (r‐apo(a)) derivatives to bind to immobilized low‐density lipoprotein (LDL) by ELISA. Removal of the apo(a) kringle IV type 8 and type 9 sequences dramatically reduced apo(a) binding to LDL. The binding of apo(a) to LDL was effectively inhibited by arginine, lysine, the

Mechanical Analysis

1939
Abstract Mechanical analysis comprises two problems: the preparation of the suspension and the analysis thereof. Preliminary treatment aims at maximum dispersion. The state of coagulation of a soil suspension depends upon the nature of the adsorbed ions and on the interaction of these ions with those of the dispersing agent.

An Analysis of Exclusive Control Mechanisms

2008 IEEE International Symposium on Parallel and Distributed Processing with Applications, 2008
Spin-lock is commonly used for process serialization, where it works well for multi processor systems. Under some conditions however, it may cause an unexpected increase of CPU overhead. To address this problem a simulator has been developed which evaluates various algorithms of the lock/unlock process to determine a method to minimize their affect on ...

Tensor Analysis with Applications in Mechanics

2010
The tensorial nature of a quantity permits us to formulate transformation rules for its components under a change of basis. These rules are relatively simple and easily grasped by any engineering student familiar with matrix operators in linear algebra. More complex problems arise when one considers the tensor fields that describe continuum bodies.

Analysis of a Sampling Servo Mechanism

Journal of Applied Physics, 1950
An analysis of a sampling servo mechanism with an error-clamping device and linear forward and return paths is given. The method leads to a determination of the continuous output of the system in terms of quadratures and gives explicitly the value of the output at the discrete sampling instants.

An analysis of mechanical cardiac assistance

Journal of Biomechanics, 1973
Abstract The effect of three methods of cardiac assistance on mean systolic pressure, mean diastolic pressure, and aortic end-diastolic pressure were analyzed theoretically in a mathematical model of the arterial system. The results indicate that: (i) The intra-aortic balloon performs better when it is large and when deflation begins before the onset

Mechanical analysis of eyelid morphology

Acta Biomaterialia, 2013
From a mechanical instability perspective a double eyelid is a double-folded thin film structure on a curved substrate, caused by compression as the film "slides" on the substrate. The underlying mechanics issues, in particular the requirements for forming a double folded structure, are studied using a modeling/simulation framework.

Analysis in Compressible Fluid Mechanics

ZAMM, 1998
Summary: The paper is concerned with numerical simulation of compressible fluid flows. We discuss several mathematical models describing compressible flows, such as the problem for the full potential transonic equation including the entropy regularization, and the use of the Euler equations, but the main attention is paid to the simulation of real gas ...

Force analysis of the patellar mechanism

Journal of Orthopaedic Research, 1987
AbstractThe aim of this study is an experimental evaluation of a force analysis of the patellar mechanism based on the assumption that patellofemoral contact is frictionless. At first, the geometric characteristics of contact surfaces, a prior knowledge of which is necessary for quantitative analysis, were measured from radiographs of 42 fresh‐frozen ...

The Analysis of Authorization Mechanisms in the Grid

2004
The characteristics of grid are outlined to point out that the traditional authorization mechanisms cannot satisfy the requirement of the grid security. Then the authorization mechanisms employed in five prevalent Grid Security Architectures are compared in terms of granularity assessment, flexibility of rights control, and achievement approach.
