introduction the aim of this study was toinvestigate the sterilization potential of atmospheric pressure plasma jet (appj) and interactions of this technology with double-stranded dna using the polymerase chain reaction (pcr) and single-strand conformation polymorphism (sscp) techniques. materials and methods the plasma jet was produced through a high voltage sinusoidal power supplyusing a mixt...

With rapid evolution of computer and the Internet technologies, e-learning has become a prevalent learning style for students and learners in different professional fields nowadays because of its convenience and flexibility along with the variety of embedded multimedia applications. In the meanwhile, in response to the potential health risk of extended computer use, many ergonomics training met...

We obtained 98 R-band and 18 B, r, i images of the optical afterglow of GRB 060526 (z = 3.21) with the MDM 1.3m, 2.4m, and the PROMPT telescopes in Cerro Tololo over the 5 nights following the burst trigger. Combining these data with other optical observations reported in GCN and the Swift-XRT observations, we compare the optical and X-ray afterglow light curves of GRB 060526. Both the optical ...

The p values of structural break tests, when the break date or dates are unknown, must be calculated in terms of the probability distributions of functions of Bessel processes. The literature so far has maintained that direct computation of these p values and of the corresponding critical values is too difficult, and has relied on approximations based on simulations, asymptotic expansions, or c...

In this paper we describe how to use a secret bug as a trapdoor to design trapped ellliptic curve E(Fp). This trapdoor can be used to mount an invalid curve attack on E(Fp). E(Fp) is designed to respect all ECC security criteria (prime order, high twist order, etc.) but for a secret exponent the point is projected on another unsecure curve. We show how to use this trap with a particular type of...

The Break-Off method is the most recent development in in-place concrete strength testing. In this method, the force required to break-off an in-place concrete cylinder 2.17 in. (55 mm) in diameter and 2-2/4 in. (70 mm) long, is related to the compressive strength of the concrete from a predetermined calibration curve developed for this concrete mix. The reliability of the BreakOff method to te...

Based on the analysis of the crack trapping effect of cleavage ridges and penetration of crack front segments in an iron–silicon alloy, the distance between break-through points along a high-angle grain boundary is investigated. If the break-through points are close to each other, the crack trapping effect is dominant; otherwise, the grain boundary separation in break-through windows governs th...
