Background: Most of our current understanding of the biological effects of exposure to ionising radiation is based on conventional cytogenetic techniques, which enable us to determine the relationship between chromosomal aberration and dose received by radiation workers. However, conventional techniques have numerous limitations and chromosomal aberrations can be easily missed. Since FISH plays...

analytical solutions and type curves for the constant rate radial flow of fluid in both conventional and naturally fractured reservoirs including the effect of wellbore phase redistribution are presented. an automated procedure for non-linear least square minimization using the analytical solutions and their derivatives with respect to the unknown parameters developed to analyze the pressure bu...

conclusions this study revealed the noticeable popularity of cam in patients suffering from chronic rheumatologic diseases, mostly due to their dissatisfaction with conventional treatments. patients and methods in this cross-sectional study, 100 randomly selected patients, with different diseases, were questioned about demographic data, disease duration, the type of cam used, reasons, visit int...

to study the effects of scale and tillage management on variability of soil properties in adjacent lands of different tillage type, soil sampling was performed linearly along contour line from the middle position of slope with 5 m intervals. in overall, 45 soil samples were collected from a field with conventional up-down tillage and 40 samples from an adjacent filed with contour tillage. soil ...

in this paper, computer simulation of a three-phase synchronous motor drive is described. this drive/system is supplied with a new type of pulse-width modulated voltage source inverter (pwm vsi) whose amplitude of the first harmonic, compared to a conventional sinusoidal pwm vsi, is increased by about 17% and whose amplitude of higher harmonics is also reduced inversely proportional to their or...

In this paper we present a very simple scheme for strengthening the conventional product-sum type PKC which has been long considered insecure against the various attacks such as the secret key attack, LLL attack, etc. We show that with the proposed strengthening scheme, the securities of the conventional product-sum type PKC’s can be much improved.
