DAMAGE MORPHOLOGICAL PARAMETERS

Morphological parameters of the acromion.

The purpose of this study was to record the basic morphometric values of the acromion. Forty-four pairs of dried scapulas were reviewed. Acromial shape was evaluated in relation to sex, symmetry and presence of subacromial enthesophytes and classified according to Bigliani with the following results: type I (flat): 26.1%, type II (curved): 55.6% and type III (hooked): 18.1%. There was a greater...

Ultrasonically induced morphological damage to mouse ovaries.

Mouse ovaries were exposed in vivo to 1 MHz continuous wave ultrasonic energy at spatial peak intensities ranging from 5 to 100 W/cm2 for times varying from 300 to 15 s depending on the intensity. Following exposure the ovaries were surgically removed at times ranging from immediately (within 60 s) to 7 days and prepared histologically for light microscopic analysis. The observed tissue alterat...

Morphological parameters for urban dispersion models

A method to calculate geometrical input parameters for urban dispersion models is presented. Two cases are considered according to the relative size of the pollutant plume compared to the building size. Applying image processing techniques to urban Digital Elevation Models (DEMs, 3-D urban databases), simple geometrical parameters over extensive urban areas are calculated. Some preliminary resu...

Morphological and Behavioral Resilience against Physical Damage for Robotic Systems

Flow thresholds of functional and morphological damage of brain tissue.

THE FUNCTIONAL STATE of the central nervous system is dependent on adequate delivery of the main substrates. For the supply of sufficient amounts of glucose and oxygen cerebral blood flow (CBF) has to be kept above a critical level. However, when perfusion drops below a certain threshold, in consequence, cerebral function becomes impaired. While the increase of blood flow above this threshold r...
