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)....

J. H. JONES AND C. RUSSELL (Department of Oral Medicine, University of Manchester) Superficial candidal penetration occurs in some cases of human oral leukoplakia which may progress to carcinoma. The relationship of mycelial penetration to leukoplakic change is not clearly understood and this experiment was designed to test the hypothesis of a direct association. One of two groups each of 60 ra...

Biological materials have developed hierarchical and heterogeneous material microstructures and nanostructures to provide protection against environmental threats that, in turn, provide bioinspired clues to improve human body armor. In this study, we present a multiscale experimental and computational approach to investigate the anisotropic design principles of a ganoid scale of an ancient fish...

using ultrasonic devices in endodontics can enhance the antibacterial and tissue dissolving ability of different root canal irrigants such as sodium hypochlorite (naocl) which is the most common irrigant with excellent antibacterial and tissue dissolving abilities. however, due to its high surface tension, its penetration into the irregularities of the root canal system is a challenge. the purp...

Abstract To describe the influence of rock thickness on penetration resistance rock-concrete composite targets, a three-dimensional model was simulated using nonlinear dynamic simulation software LS-DYNA. The four targets with thicknesses 10-20, 20-20 cm, 30-20 and 40-20 cm by projectile at target angle 75 degrees is investigated in this study. A damage cloud diagram plate obtained, curves spee...

In this study, the dermal penetration rate of carbofuran, carbosulfan, and furathiocarb has been measured with rat abdominal skin using the static diffusion cell. The technical grades of three compounds were applied at different doses on skin surface mounted in static diffusion cell and incubated at 32 C for 48 h with shaking. The same procedures were carried out with furathiocarb EC (emulsifia...
