Cation exchange capacity (CEC) is one of the most important soil attributes which control some basic properties of soil such as acidity, water and nutrient retaining capacity. However, the measurement of cation exchange capacity in large areas is time consuming and requires high expenses. One way to save time and expenses is to use simple soil covariates and geostatistical methods in mapping CE...

The article is devoted to the study of functioning English adjectival emotive units denoting positive semantics as direct linguistic means representing human emotional states that combine semantic and pragmatic components meaning. aim this paper determine features with meaning in modern English. defined approach investigation led use those research methods correspond best its goals: particular,...

Detecting the mineralization component is one of the main subjects in geochemical exploration. Various techniques have been introduced to explore favorite zones and separate the anomaly from background, such as bivariate or multivariate statistical analysis. The main objectives is to identify the spatial variability and main sources of some special elements in Qare Char, in northwest of Iran, b...

The utilization of symbolic and semisymbolic algorithms as the effective tools supporting partial design stages of analogue filters is introduced. The corresponding software has been designed for supporting main design stages of both the passive and active filters effectively: a principle verification using the symbolic analysis, modeling of the influence of real component parameters using the ...

In this study, the relationship among the concepts of entropy generation rate, entransy theory, and generalized thermal resistance to the optimal design of thermal systems is discussed. The equations of entropy and entransy rates are compared and their implications for optimization of conductive heat transfer are analyzed. The theoretical analyses show that based on entropy generation minimizat...
