چکیده
Modifications in recorder standardization are required to correct inherent scalar differences among potential differences measured in a given electrocardiographic reference frame. In the frontal plane, agreement between the resultant vectors calculated from unipolar limb lead measurements and from standard lead measurements can be obtained by standardizing the galvanometer for recording the unipolar limb lead potentials at V/3 cm. per millivolt. A method for calculating this "standardizing factor" and similar factors for other reference frames is presented and applied to calculations for the equilateral tetrahedron, the isosceles tetrahedron, and the cube.

Five treatments including Conway medium, media containing 0.1, 0.17, 0.3 and 0.5 mg l-1 ferrous (Fe; in the first experiment), media with 1, 1.26, 1.59, 2 mg l-1 concentrations of phosphorous (P; in the second experiment) and a pure sample of Tetraselmis suecica were cultured under laboratory conditions. Growth rate of the algae was determined using the optical density method at 750 nm and numb...

متن کاملA Statistical Analysis of the Aircraft Landing Process
Managing operations of the aircraft approach process and analyzing runway landing capacity, utilization and related risks require detailed insight into the stochastic characteristics of the process. These characteristics can be represented by probability distributions. The focus of this study is analyzing landings on a runway operating independent of other runways making it as a single runway. ...
