The phenomenon of soil liquefaction can be an induced effect earthquake shaking where the saturated loses some or all its bearing capacity and stiffness. Likewise, increase water pressure in pores under seismic wave causes a decrease shear strength. As result, becomes liquefied susceptible to producing permanent deformations. is generally unpredictable, neglecting it influence stability structu...

CONTEXT The effectiveness of cold lateral compaction depends on the root canal preparation and used gutta-percha cone. AIMS The aim of this study is to evaluate finger spreader penetration into root canals prepared with ProTaper (PT) or Reciproc (Rec) systems and filled with gutta-percha cones with different tapers. MATERIALS AND METHODS Twenty-four simulated root canals in resin blocks wit...

The correct interpretation of in situ and laboratory test results is an important step the design mining tailing containment structures. This study aims to analyze Seismic Cone Penetration Test (SCPTu) obtained into a reservoir composed two material layers: thick-dry tick-saturated. It possible observe that same reservoir, CPTu can lead classification each layer as different soil with specific ...

introduction: various materials and methods have been recommended for successful root canal obturation. the aim of this experimental in vitro study was to compare the sealing ability of three root canal sealers ah-26, glass ionomer cement (gic) and zinc oxide eugenol (zoe) in single gutta-percha obturating system. methods and materials: seventy extracted single-rooted human teeth were decoronat...

The move to the cloud brings a number of new security challenges, but the application remains your last line of defense. Engineers are extremely well poised to perform tasks critical for securing the application—provided that certain key obstacles are overcome. Cloud Shifts the Burden of Security to Development

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 ...

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)....
