A Method to Quantify Combustible Carbon

A New Method to Quantify Mitral Regurgitation

INTRODUCTION In cases of mitral regurgitation, the severity of the regurgitation is the major determinant of progression to left ventricular dilatation and dysfunction. Therefore, precise measurement of regurgitant volume in patients with mitral regurgitation is important for evaluating the progression of the disease which can then determine the optimal time for surgical repair or replacement. ...

[A new method to quantify subjective aniseikonia].

PURPOSE To design subjective aniseikonia measuring criteria in order to quantify its value and to use it to the clinical practice. MATERIAL AND METHODS In order to carry out the aniseikonia measurements, a sinoptophore (Clement Clark) was used and two tests (one per eye of each patient) were performed. A viewfinder capable of measuring the difference in size between subjective images in both ...

A carbon isotope method to quantify groundwater discharge at the land-sea interface

We present a new method to characterize and quantify groundwater discharge to estuaries and the coastal ocean. Using data from the Pages Creek estuary in the Cape Fear region of southeastern North Carolina, we show that the concentration and carbon isotopic composition (D14C and d13C values) of dissolved inorganic carbon (DIC) can provide a tracer of a single, well-defined component of the surf...

Estimation of Carbon Dioxide, Oxygen and Combustible Gases by Krogh's Method of Micro-Analysis.

Entropy generation method to quantify thermal comfort.

The present paper presents a thermodynamic approach to assess the quality of human-thermal environment interaction and quantify thermal comfort. The approach involves development of entropy generation term by applying second law of thermodynamics to the combined human-environment system. The entropy generation term combines both human thermal physiological responses and thermal environmental va...
