Electronic commerce revolutionises both global economies and marketplace. A number of developed countries have demonstrated clear leadership in eCommerce, as demonstrated by the level of ICT penetration in organisations and households. However, traditional economies have experienced a much slower uptake of eCommerce. This is attributed to difficulties in enhancing the usage of personal computer...

In this study we explore the global effect of the Internet on democracy over the period of 1992 to 2002 by observing the relationships between measures related to democracy and Internet prevalence. Our results show a significant correlation between Internet penetration (measured as the estimated number of Internet users per 1,000 people) and a common indicator of a nation’s level of democratiza...

One of the most valid and efficient models of long rod projectile penetration in homogeneous targets is Tate and Alekseevskii’s (A&t) model. Based on Tate’s model, the present research tries to calculate the optimum speeds to achieve the maximum penetration depth in the homogeneous targets. The proposed collision speed-penetration depth diagrams are developed using Tate’s model. In this way, va...

This exploratory paper attempts to describe the status of the international digital divide in the Mediterranean area. To do so, it has assembled data on the level of Internet penetration in the Union for the Mediterranean (UM), Some non-littoral UM states were included for purposes of comparison, as were a number of EU non-UM states. Finally, a small number of non UM, non EU, OECD members were ...

Tissue that is damaged and poorly oxygenated as a result of swelling, trauma or inflammation has been shown to have a positive response to laser therapy irradiation. Deep penetrating photons activate a biochemical cascade of events leading to rapid cellular regeneration, normalization and healing. Laser light energy is highly absorbed by skin and subcutaneous tissue, therefore, penetration is k...

OBJECTIVES/HYPOTHESIS To determine the sensitivity and specificity for assessing pharyngeal residue, laryngeal penetration, and tracheal aspiration when comparing findings from the Static Endoscopic Evaluation of Swallowing (SEES) with findings from the Videofluoroscopic Swallow Study (VFSS). METHODS Retrospective study at a tertiary academic medical center. Records were reviewed consecutive ...

BACKGROUND Through chemomechanical debridement of the root canal is a primary requisite for successful endodontic therapy. Thus the aim of this study was to evaluate the effects of using QmiX alone, QmiX with EndoActivator and QmiX with Er,Cr:YSGG laser for final irrigation on sealer penetration into the dentinal tubules. MATERIAL AND METHODS 75 extracted human mandibular premolar teeth were ...
