Introduction: A thorough knowledge of the anatomic morphology of the root canal system is necessary for the long-term success of the root canal therapy. The occurrence of C-shaped root canal configuration is one such variation. Achievement of favorable prognosis after commencing root canal therapy in such teeth is one of the challenges imposed on the endodontist. Hence, we evaluated the healing...

We present a C-shaped nanoaperture-enhanced Ge photodetector that shows 2-5 times the photocurrent enhancement over that from a square aperture of the same area at 1310 nm wavelength. We demonstrate the polarization dependence of the C-aperture photodetector over a wide wavelength range. Our experimental observation agrees well with finite-difference time-domain simulation results.

When interpolating a network of curves to create a C surface from spline patches, the network has to satisfy an algebraic condition, called the vertex enclosure constraint. We show the existence of a similar, additional constraint that governs the admissibility of curve networks for G interpolation by smooth patches.

A 23 year old female patient came to our Department of Conservative Dentistry and Endodontics, Kamineni Institute of Dental Sciences, Nalgonda, with a chief complaint of pain in the mandibular left second molar. The patient had no significant medical history. Subjective symptoms of prolonged sensitivity to hot and cold were present. The objective symptoms were observed as percussion sensitivity...

One of the well-known NP-complete problems in graph theory is the Hamiltonian path problem; i.e., finding a simple path in the graph such that every vertex visits exactly once [5]. The two-dimensional integer grid G is an infinite undirected graph in which vertices are all points of the plane with integer coordinates and two vertices are connected by an edge if and only if the Euclidean distanc...

Introduction: Compared to broadband antennas, reconfigurable microstrip antennas offer the advantages of compact size, frequency selectivity and similar radiation pattern and gain for all designed frequency bands [1]. Several interesting approaches to electronic tunability for different antenna structures have been carried out. However, the tuning mechanisms used are complex and need extra matc...

Enclosure is an effective strategy for enhancing soil carbon sequestration in the desert steppe. Soil organic (SOC) and its stock during changes plant community influence fertility global cycle. We studied SOC along with six types steppe of Inner Mongolia, northern China. The goal this study was to explore differences among communities while accounting effects environmental factors. collected 3...

A transonic air stream flowing over a rectangular cavity or enclosure is unsteady. At certain flow conditions, large scale oscillations develop in the shear layer which, for an open cavity, spans across the whole enclosure. The convected shear layer instabilities interact with the cavity geometry, they generate resonance, and induce large amplitude wall pressure fluctuations, aerodynamic pressu...

A group of Hanuman langurs (Presbytis entellus) was studied before and after it was moved from an old cage-style enclosure to a novel naturalistic environment at the London Zoo. Eating and locomotion occupied more of the langurs’ time in their new enclosure, whereas dozing, allogrooming, and aggression decreased, along with an increase in inter-individual distances. These changes are attributed...
