Penetration testing entails attacking a system to identify and report insecurity, but doing so without harming the system nor encroaching on the dignity of those affected by it. To improve the interaction between penetration testers and their processes and technology, we need to understand the factors that affect decisions they make with ethical import. This paper presents four ethical hazards ...

Density functional theory calculations were performed to investigate the endohedral and exohedral adsorption of a H2 molecule on the classical and nonclassical fullerenes Cx (x=58, 59, 60, 62) with seven-, eight-, and ninemembered rings. The amplitude of adsorption energies are within 0.03eV and the molecule-fullerene interaction belongs to van der Waals type. Penetration of a H2 molecule throu...

This paper reports about the analysis of the Internet diffusion among families and business basing on daily observations on registrations of second level domain names underneath the “.it” ccTLD . In particular, domains registered by individuals are analysed. The penetration rate over the relevant population of potential adopters is computed at highly disaggregated geographical level (province)....

there are continuous connections between a city and its periphery and the form of these relations varies. collection of these relations makes an influential area forming the various relations between the city and periphery. these relations are not the same and do not have unique concentration and density rather, they hey depend on population, geographic conditions and the role of the city in th...

This paper presents a modified form of the Walker-Anderson (W-A) model for analyzing high velocity penetration of an eroding projectile into a concrete target in which the W-A model is improved by incorporating calculations for the plastic flow field of concrete in terms of its compressibility and strain rate sensitivity under severe pressure. With the changes to and calculations of plastic fie...

Ceftriaxone is a versatile and useful "third-generation" cephalosporin that needs to be administered once-daily. Ceftriaxone is a β-lactamase-resistant cephalosporin. It is active against important gram-positive and most gram-negative bacteria. The MIC90s of ceftriaxone are 0.1 µg/ml for Escherichia coli, 0.1 µg/ml for Klebsiella species, 0.2 µg/ml for Proteus species, 0.3 µg/ml for Enterobacte...

Objective: The goal of endodontic treatment is to eliminate bacteria and their products from the root canal. Bacteria are main etiological factors pulpal periapical diseases. Chemomechanical preparation administration canal medicaments cannot completely in system, especially Enterococcus faecalis, which have high resistancy, therefore, an ideal obturation material required. Adequate filling qua...

This paper describes a planned program of investigation designed to determine what characteristics are signficant in predicting performance of students used as subjects in IT system penetration testing testbeds. In large part the experimental design replicates an earlier study by Jonsson et al., and extends that study to include factors describing the attacking subjects. In this way the propose...
