Thanks to author with a good and challengeable announcement for article 8(1):66-68. Electrical power is an integral part of modern civilization. Static electric and magnetic fields, as well as low-frequency fields (at 50 or 60 Hz), are produced by both natural and man-made sources. At extremely lowfrequency (ELFs), the photon energy is exceedingly small, thus it cannot damage to DNA in a direct...

OBJECTIVE To determine the frequency of factor VIII specific inhibitors in haemophilia A. STUDY DESIGN Cross-sectional study. PLACE AND DURATION OF STUDY National Institute of Blood Disease and Bone Marrow Transplantation, Karachi, from August 2007 to March 2009. METHODOLOGY Venous blood samples of diagnosed haemophilia A patients were collected in tubes containing 0.109 M (3.2%) trisodiu...

We present an integrated scheme for dielectric drive and read-out of high-Q nanomechanical resonators that enable tuning of both the resonance frequency and quality factor with an applied dc voltage. A simple model for altering these quantities is derived, incorporating the resonator’s complex electric polarizability and position in an inhomogeneous electric field, which agrees very well with e...
