The mechanisms which enable the vast majority of computer attacks are based on design and programming errors in networked applications. The growing use of voice over IP (VOIP) phone technology makes these phone applications potential targets. We present a tool to perform security testing of VOIP applications to identify security vulnerabilities which can be exploited by an attacker. Session Ini...

many factors affect tobacco quit rate. in this study we investigated the abstinence rate after 5 years based on the age of smoking initiation. this pre-post field trial study was conducted on 398 smokers who participated voluntarily in a smoking cessation clinic in 2005. they were followed for 5 years and their success or failure in continuous abstinence was evaluated and recorded in 2010. thre...

context appropriate management of neonates, tested positive for congenital hypothyroidism (ch), in particular, the initial dosage of levothyroxine and the time of initiation of treatment is a critical issue. the aim of this study was to assess all current evidence available on the subject to ascertain the optimal initial dose and optimal initiation time of treatment for children with ch. eviden...

interactive effect of plant growth regulators6-benzylaminopurine (bap) (0, 2, 4 and 8 µm) and1-naphtalene acetic acid (naa) (0, 0.05, 0.25 and 0.5µm) in van der salm (vs) medium was used to optimize in vitro propagation of rosa hybrida cv. iceberg.shoot proliferation and number of new leaves weremeasured as growth indicators. as the concentrationof bap was raised, growth rate increased with all...

analytical detection of cracking in connections of steel moment resisting frames using simple damage indices is important since these cracks are not visible unless the connections are uncovered. in this paper, applicability of three cumulative damage indices for detection of cracking in a cover plate welded moment connection is investigated. the damage indices considered in this study are based...

The effect of chemical reactions on the blast initiation of detonation in gaseous media has been investigated in this paper. Analytical method is based on the numerical solution of onedimensional reactive Euler equations. So far, analyses on the blast initiation of detonation have modeled the combustion process as a one-step chemical reaction, which follows the Arrhenius rate law. Previous stud...
