This paper introduces the indicators for surge arrester condition assessment based on the leakage current analysis. Maximum amplitude of fundamental harmonic of the resistive leakage current, maximum amplitude of third harmonic of the resistive leakage current and maximum amplitude of fundamental harmonic of the capacitive leakage current were used as indicators for surge arrester condition mon...

The present paper investigates the effects of the trapezoidal teeth labyrinth seal on the leakage amount in gas turbines. The influences of increasing the number of teeth from 1 to 6 with step 1 and the tip clearance s=0.5 to 7.5 mm on the leakage flow at different pressure ratios of PR=1.5, 2 and 2.5 are examined, comprehensively. The analysis is performed numerically using a Finite-Volume...

With the scarcity of good quality water, plants like tomatoes will be more susceptible to excess boron (EB) in Mediterranean regions. The effects EB on growth, free, semi-bound, and bound (B) concentrations, macromolecules Solanum lycopersicum L. cultivar Castle Rock, were investigated this study. Seedlings exposed four levels using boric acid. results manifested that inhibited tomato total wat...

Photodynamic therapy with bacteriochlorin a (BCA) as sensitizer induces damage to red blood cells in vivo. To assess the extent of the contributuion of reactive oxygen species (ROS) and to determine a possible reaction mechanism, competition experiments with assorted ROS quenching or/and enhancing agents were performed in human erythrocytes as model system and in phosphate buffer. In the erythr...

Authenticated encryption schemes in practice have to be robust against adversaries that have access to various types of leakage, for instance decryption leakage on invalid ciphertexts (protocol leakage), or leakage on the underlying primitives (side channel leakage). This work includes several novel contributions: we augment the notion of nonce-base authenticated encryption with the notion of c...
