The aim of this laboratory study was to compare the interfacial adaptation of an epoxy-resin and a self-etch sealer in mesial root canals of mandibular molars filled using the System-B/Elements Obturation Unit. Sixty mesial root canals of mandibular molars were prepared using the K3 rotary system up to 35.04 instrument and then filled with the aid of the System-B/Elements Obturation Unit using ...

Tatarl? Höyük is one of the largest settlements Cilicia Pedias (Campestris). It located on important commercial and military routes at western exit Amanus Mountains, in eastern part Ceyhan district Adana. also close to Hittite-Kizzuwatna Caravan Road connected Central Anatolia by this route. This article discusses a seal two impressions found excavations 2013 2015. One without an inscription ca...

Measurement of fault rock and seal rock flow properties presents considerable problems, even in the controlled conditions of the laboratory. Estimating of the sealing capacity and rate of leakage across faults or shale layers is an even greater challenge. The purpose of this contribution is to examine, with examples, how a combination of existing and novel petrophysical methods could reduce unc...

In this paper quantum seals will be introduced. A quantum seal is a way of encoding a classical message into quantum states, so that everybody can read the message error-free, but at the same time the sender and all intended readers who have some prior knowledge of the quantum seal, can check if the seal has been broken and the message read. The verification is done without reading nor disturbi...

This paper presents a general method for studying the mechanical properties of a ferrofluid seal by using a three-dimensional analytical approach based on the coulombian model of a magnet. The fundamental Maxwell’s equations lead us to define the concept of magnetic energy of the ferrofluid seal by using only the three-dimensional equations of the magnetic field created by ring permanent magnet...

712 Soil physical conditions can aff ect diff usion, environmental fate, and effi cacy of fumigants in soil disinfestation treatments. Water seals (applying water using sprinklers to soil following fumigation) can eff ectively reduce fumigant emissions from sandy loam soils. Soil column studies compared the eff ectiveness of water seals in reducing cis-1,3-dichloropropene (1,3-D) emissions from...

RATIONALE Mixing models are a common method for quantifying the contribution of prey sources to the diet of an individual using stable isotope analysis; however, these models rely upon a known trophic discrimination factor (hereafter, TDF) that results from fractionation between prey and animal tissues. Quantifying TDFs in captive animals is ideal, because diet is controlled and the proportiona...

Colorectal anastomotic leakage (AL) is a serious complication in colorectal surgery leading to high morbidity and mortality rates. The incidence of AL varies between 2.5 and 20%. Over the years, many strategies aimed at lowering the incidence of anastomotic leakage have been examined. The cause of AL is probably multifactorial. Etiological factors include insufficient arterial blood supply, ten...
