one of the major strengths of a geographic information system (gis) in geosciences is the ability to integrate and combine multiple layers into mineral potential maps showing areas which are favorable for mineral exploration. these capabilities make gis an extremely useful tool for mineral exploration. several spatial modeling techniques can be employed to produce potential maps. however, these...

Body surface potential mapping (BSPM) was performed in female rats with pulmonary arterial hypertension (PAH) induced by a single subcutaneous injection monocrotaline (60 mg/kg body wt). Analysis of data was produced by equipotential momentous maps during ventricle depolarization. In rats with monocrotaline-induced PAH was confirmed hypertrophy of the right ventricle. It is reflected on equipot...

Soil is one of the most important natural resources covering a large area of the land surface. Soil plays a vital role in biosphere processes, such as energy balance, hydrology, biochemistry, and biological productivity. It supports plants that supply foods, fibers, drugs, and some other human needs. Conversely, desert regions include about one third of earth lands and these regions have increa...

in this work, the (100) surface of au and pts face centered cubic lattice, has been simulated in monte-carlo method, using a 486-dx2 computer. the potential equation that was used for the interaction among atoms in the metal surfaces is called sutton and chen potential. this potential is introduced for the interaction of floating nuclei in the electron sea, and attractive term is a many body po...

Identification of patients at significant risk of arrhythmia and sudden cardiac death is one of today’s major cardiology challenges. Although tremendous progress has been made in detecting and characterizing cardiac disease and its progression, largely through imaging modalities, progress in detecting and monitoring changes in arrhythmogenic states has been incremental and has not resulted in r...

BACKGROUND In this study we propose the development of a new algorithm for selecting optimal recording sites for limited lead body surface potential mapping. The proposed algorithm differs from previously reported methods in that it is based upon a simple and intuitive data driven technique that does not make any presumptions about deterministic characteristics of the data. It uses a forward se...

According to theoretical and clinical considerations the risk of re-entry type malignant arrhythmia can be predicted by body surface QRST integral maps. Our aim was to understand better the intracardiac processes causing noninvasively measurable action potential (AP) heterogeneity. For this task we used a computer model of human cardiac ventricles with modifiable AP patterns to investigate the ...

The availability of collisional rate coefficients is a prerequisite for an accurate interpretation of astrophysical observations, since the observed media often harbour densities where molecules are populated under non-local thermodynamic equilibrium conditions. In the current study, we present calculations of rate coefficients suitable to describe the various spin isomers ofmultiply deuterated...
