introduction: microleakage is of the causes of endodontic treatment failure. the aim of this in vitro study, was to compare the microleakage of mineral trioxide aggregate (mta) and calcium-enriched mixture (cem) cement apical plugs in three environments. methods and materials: a total of 130 human extracted single rooted teeth were collected. after decoronation, preparation of the root canal sp...

Although nodes in a network-virtualization infrastructure, which is called a virtualization node, usually contain a switch or a router with sophisticated and high-performance functions such as Ethernet switching, VLAN, and IP routing, most of such infrastructure functions cannot be reused as program components by slices. Accordingly, a method for providing such functions to slices on a virtuali...

The need for a mechanism to control and filter subscriptions to control system variables by the client was described in a paper at the ICALEPCS2009 conference [1]. The implementation follows a plug-in design that allows the insertion of plug-in instances into the event stream on the server side. The client can instantiate and configure these plug-ins when opening a subscription, by adding modif...

BACKGROUND Bone tunnel enlargement is a phenomenon present in all anterior cruciate ligament (ACL)- reconstruction techniques. It was hypothesized that press-fit fixation using a free autograft bone plug reduces the overall tunnel size in the tibial tunnel. METHODS In a prospective cohort study twelve patients who underwent primary ACL reconstruction using an autologous quadriceps tendon graf...

This paper presents a smart DC micro-grid system for plug-in electric vehicle charging and discharging. This DC microgrid integrates the plug-in battery electric vehicles (BEVs) & plug-in hybrid electric vehicles (HEVs) together with the AC supply module, storage energy module, and intelligent control module. By connecting with the AC power source and the storage energy module, this grid can of...

apexification is a method of inducing apical closure for non-vital immature permanent teeth. during this treatment a mineralized barrier is induced [with long term calcium hydroxide (ch) treatment]; or artificially created [with mineral trioxide aggregate (mta) plug]. this article describes two cases of apexification in immature necrotic teeth treated with these two different techniques. after ...

The percent of energy consumed by plug load equipment in commercial buildings is on the rise. Research conducted in the past has included surveying plug load equipment, measuring plug load electricity consumption and equipment operating patterns, and studying plug load reduction solutions in office buildings, but plug load energy use across other building types is poorly understood. A universit...

PURPOSE To report a case of extrusion of a new soft punctum plug with thermoexpansion property (Medennium SmartPLUG). METHODS A soft punctum plug was implanted in a 32-year-old woman with a severe dry eye syndrome in juvenile arthritis. RESULTS One week after implant the plug partially extruded outside the punctum. Despite this adverse event, all subjective dry eye symptoms improved. CONC...
