The sensitivity, specificity and reproducibility of molecular genetic methods analysis largely depend on the quality preliminary preparation analyzed samples. During sample preparation, tasks disinfecting pathogenic material, lysing cell membranes, removing compounds impurities that inhibit polymerase chain reaction (PCR), as well concentrating nucleic acids are solved. purpose this work is to ...

This paper proposes a new method for transmission loss allocation. The share of each bus in the transmission line losses is determined using transmission line loss equations with respect to bus-injected currents. Then, it is applied to the total network transmission lines. In the proposed method, comparing with other methods, a solution to remove the negative loss allocation has been introd...

The goal of paper is to present the magnetic field calculations in high current bus ducts. Finiteelement method is used to do this. Bus ducts under study have figure such as circle area. Thecalculations will be using mathematical relations, meshed geometric shape and analyzing them.Geometric mean will help us to determine the value of magnetic field. COMSOL software is appliedfor simulation stu...
