The root canal anatomy of mandibular incisors can present a number of variations . This case report illustrates the abnormal configuration and successful non-surgical endodontic management of complex canal systems in mandibular lateral incisors.

In this paper we present an analysis of a new configuration for achieving spin stabilized magnetic levitation. In the classical configuration, the rotor spins about a vertical axis; and the spin stabilizes the lateral instability of the top in the magnetic field. In this new configuration the rotor spins about a horizontal axis; and the spin stabilizes the axial instability of the top in the ma...

It is reported that when a light beam travels through a slab of left-handed medium in the air, the lateral shift of the transmitted beam can be negative as well as positive. The necessary condition for the lateral shift to be positive is given. The validity of the stationary-phase approach is demonstrated by numerical simulations for a Gaussian-shaped beam. A restriction to the slab's thickness...

to report the oral findings, including dental anomalies, ectopic eruption of the maxillary permanent first molars and periodontal disease and soft tissue alterations, in a subject with apert syndrome. clinical and radiographic examination of a patient with apert syndrome, aged 21 years old, not previously submitted for orthodontic or orthognathic treatment. dental anomalies were present in a pa...

In this paper we present a method for moving objects detection and labeling denominated Lateral Interaction in Accumulative Computation (LIAC). The LIAC method usefulness in the general task of motion detection may be appreciated by means of some step-by-step descriptions of significant examples of object detection in video sequences of synthetic and real images.

BACKGROUND The aim of the study was to determine the root canal morphology of permanent mandibular incisor teeth in the Indian subpopulation with the use of cone beam computed tomography (CBCT). MATERIAL/METHODS CBCT images of 200 patients with 800 permanent mandibular incisors, fulfilling necessary inclusion criteria and aged 18 to 60 years were evaluated. The number of roots, number of root...

We begin an exploration of the capacity of the stationary accretion shock instability (SASI) to generate magnetic fields by adding a weak, stationary, and radial (but bipolar) magnetic field to a spherically symmetric fluid configuration that models a stalled shock in the post-bounce supernova environment. Upon perturbation the SASI develops, and its lateral flows alternately advect the initial...

This paper describes an exploratory study of configurations and coordination mechanisms for IT governance in European-based transnational companies. IT governance is traditionally defined as the formal allocation of IT decision-making authority. Rooted in organisation design theory, a research framework is proposed and comparative case study research is conducted in three large financial servic...

OBJECT Aneurysms of the vertebral artery (VA) and proximal posterior inferior cerebellar artery (PICA) are rare and challenging lesions, as they are located in front of the brainstem and surrounded by the lower cranial nerves. Many different approaches have been described for their treatment, and have yielded different results. With the use of different examples of lesions, the authors describe...
