Abstract Background: Several single nucleotide polymorphisms have been found in CYP1A1 gene and it was reported that C allele in T/C gene polymorphism is associated with lung cancer. Current study investigates interaction between cigarette factor and C/T polymorphism in the m1 locus. Methods: Present study is a case-control and retrospective study. T/C polymorphism in 112 patients with lung...
In this article, using distribution kernel, we study the nonlinear equations with n-dimensional telegraph operator iterated k-times. Keywords—Telegraph operator, Elementary solution, Distribution
n this paper a finite element model has been proposed for evaluation of primary and secondary current density values on the cathode surface in nickel electroplating operation of a revolving part. In addition, the capability of presented electroplating simulation has been investigated in order to describe the electroplated thickness of the nickel sulfate solution. Nickel electroplating experi...
In most highly developed electrical power system, there are several difficulties related from generation to distribution. Usually, power generation is located at remote area from the load center. Long transmission and distribution lines have to be constructed and maintained to meet required reliability, power quality and economic point of views. Reliable, cheap, efficient conductor is required ...
Personal computers draw non-sinusoidal current with odd harmonics more significantly. Power Quality of distribution networks is severely affected due to the flow of these generated harmonics during the operation of electronic loads. In this paper, mathematical modeling of odd harmonics in current like 3, 5, 7 and 9 influencing the power quality has been presented. Live signals have been capture...
Metal oxide surge arresters (ZNO) are used widely in power system to protect equipments from over voltages. Non uniform potential distribution leads to the depressed service life and low safe reliability, so grading ring is applied on HV surge arrester order to uniform the electric field distribution. One of the problems of arresters is leakage current in power frequency that different paramet...
