market structure is one of the most important characteristics of every industry. although, there exist different indices such as concentration, economies of scale, entry of firms, product differentiation, etc. for the evaluation of market structure, but most of the studies in the subject have used only one of these indices (usually concentration). in this study, by application of fuzzy inferenc...

Introduction: Bispectral Index is an objective tool to assess electroencephalographic activity and measure the effect of certain sedatives and hypnotics on the brain. In addition, there are certain subjective tools such as the observer's assessment of alertness and sedation which are used. The correlation between BIS and the concentration of propofol in the brain, and the relationship between t...

in this study, functional properties of red bean, chickpea, lentil and canellini bean were evaluated. our results revealed that beans had the highest emulsifying capacity. this property was minimum at the isoelectric point (about 4) among all samples which is in concistent with their solubility curves. salt concentration of 0.5 m did not have a significant influence on emulsifying capacity but ...

The empirical literature on the measurement of health inequalities is vast and rapidly expanding. To date, however, no foundation in welfare economics exists for the proposed measures of health inequality. This paper provides such a foundation for commonly used measures like the health concentration index, the Gini index, and the extended concentration index. Our results indicate that these mea...

We explore the stability of different galaxy light concentration indices as a function of the outermost observed galaxy radius. With a series of analytical light-profile models, we show mathematically how varying the radial extent to which one measures a galaxy’s light can strongly affect the derived galaxy concentration. The “mean concentration index”, often used for parametrizing high-redshif...

Compact low-cost sensors for measuring particulate matter (PM) concentrations are receiving significant attention as they can be used in larger numbers and in a distributed manner. Most low-cost particle sensors work on optical scattering measurements from the aerosol. To ensure accurate and reliable determination of PM mass concentrations, a relationship of the scattering signal to mass concen...

BACKGROUND Dietary glycemic index, an indicator of the ability of the carbohydrate to raise blood glucose levels, and glycemic load, the product of glycemic index and carbohydrate intake, have been positively related to risk of coronary heart disease. However, the relationships between glycemic index and glycemic load and high-density lipoprotein cholesterol (HDL-C) concentration in the US popu...
