POROUS STONE N.P. Avdelidis, E.T. Delegou, and A. Moropoulou 1 IRT & Materials Consultancy, Volos, Greece; 2 National Technical University of Athens, Athens, Greece Abstract: In this work, infrared thermography was employed as a monitoring technique during water capillary rise tests on a choice of porous stones in the laboratory, as well as in situ on a cleaned porous stone surface of a histori...

We discuss the rise of a liquid inside an angular capillary tube. It is shown that for a wetting liquid, the height of the rise is (as usually) inversely proportional to the length which characterizes the confinement. The exact laws deduced from energetic considerations are found to be in excellent agreement with the data. We then show how such tubes can be used to prevent bubbles from being tr...

abstract         background and objective: normal hemoglobin (hb) is formed of a heme group and a protein group known as globin. globin is made of four polypeptide chains and in hemoglobinopathies, the structure of one of these four polypeptide chain becomes abnormal. cellulose acetate method is a common way to differentiate haemoglobinopathies. inability to identify the components of hb low co...

The dramatic rise in height of the meniscus within a capillary, the other end of which is immersed in a liquid undergoing ultrasonic cavitation, represents a novel, robust and inexpensive method for monitoring cavitational activity. Here this effect is compared quantitatively with the multibubble sonoluminescence, which is simultaneously being emitted by the sample. A comparison is made of both...

Background: Hemoglobinopathies are the commonest single gene disorder in human that affect hemoglobin production and function that occur when mutations alter the amino acid sequence of globin chains. The purpose of the present study was to evaluate the prevalence of hemoglobninopathies detected by capillary electrophoresis method in individuals referred to Masjed-Soleiman health centers by capi...

Muscle contractions evoke an immediate rise in blood flow. Distribution of this hyperemia within the capillary bed may be deterministic for muscle O(2) diffusing capacity and remains unresolved. We developed the exteriorized rat (n = 4) spinotrapezius muscle for evaluation of capillary hemodynamics before (rest), during, and immediately after (post) a bout of twitch contractions to resolve (sec...
