Following previous presentations on the dangers penetration testers face in using current off-the-shelf tools and practices (Pwn the Pwn Plug and I Hunt Penetration Testers), this paper and presentation explores how widely available learning materials used to train penetration testers lead to inadequate protection of client data and penetration testing operations. Widely available books and oth...

The International Telecommunications Union (ITU) and the Organization for Economic Cooperation and Development (OECD) provide Internet penetration statistics, which are collected from official national sources worldwide, and they are widely used to inform policymakers and researchers about the expansion of digital technologies. Nevertheless, these statistics are derived with methodologies, whic...

wind is an important erosive force in deserts, where limited cover of vascular plant material offers little soil-surface protection. erosion and sediment from soil surfaces occurs when wind forces exceed soil threshold friction velocities. soils with physical or biological crusts usually resist wind erosion. this study was conducted by the aim of investigation the effect of trichoderma harzianu...

depth of frost penetration is one of the main indices in agriculture, civil and transportation engineering. soil temperature is a function of several factors including: topography, solar radiation, air temperature, moisture content and other physical properties of soil such as thermal capacity, coefficient of heat conductivity, and specific heat. the main objective of the present paper is to de...

Studies on the adoption of innovations by companies generally include micro-level and mesolevel variables in order to explain a company’s receptiveness to innovations. This study adds to the literature by investigating the role of macro-level variables (i.e. national culture) to explain differences in innovation penetration levels and adoption decisions by companies across national cultures. A ...

simultaneous heat and water model (shaw) is based on the assimilation rate of melting and/or freezing of the accumulated snow as well as melting of ice in soil. the main objective of this study was to evaluate applicability of shaw model in determining maximum depth of frost penetration in soils in some typical climates of iran. to this end, the daily data of air temperature, soil temperatures ...

The purpose of this study was to determine how accurately periodontal probes measure connective tissue attachment levels in beagle dogs with (1) clinically healthy gingivae, (2) experimental gingivitis, and (3) periodontitis. In the healthy and experimental gingivitis specimens the probes were inserted with a standardized force of 25 ponds. In periodontitis specimens the probes were inserted wi...

Car exhaust is one of the most common causes ozone hole aggravation, electrical vehicles (EVs) represent a promising solution to avoid this problem. Despite benefits EVs, their random charging behavior some difficulties regarding electric network performance, such as increased energy losses and voltage deviations. This paper aims achieve proper scheduling EVs process, its negative impacts on ne...
