Restorative and endodontic procedures have been recently developed in an attempt to preserve the vitality of dental pulp after exposure to external stimuli, such as caries infection or traumatic injury. When damage to dental pulp is reversible, pulp wound healing can proceed, whereas irreversible damage induces pathological changes in dental pulp, eventually requiring its removal. Nonvital teet...
The hybrids of ATLAS semi-conductor tracker (SCT) were made with Cu/Polyimide flex-circuits, reinforced with carbon-carbon substrates, in the barrel and in the endcap modules. We report successes, problems and solutions in the course of production of 2600 pieces of hybrids each.
Vitality of dental pulp is essential for long-term tooth survival. The aim of vital pulp therapy is to maintain healthy pulp tissue by eliminating bacteria from the dentin-pulp complex. There are several different treatment options for vital pulp therapy in extensively decayed or traumatized teeth. Pulp capping or pulpotomy procedures rely upon an accurate assessment of the pulp status, and car...
We propose a new model for describing baryon semi-leptonic decays for estimating F and D values with explicit breaking effects of both SU(3) and SU(2) flavor symmetry, where all possible SU(3) and SU(2) breaking effects are induced from an effective interaction. An overall fit including the weak magnetism form factor yields F = 0.477 ± 0.001, D = 0.835 ± 0.001, Vud = 0.975± 0.002, and Vus = 0.2...
We have developed a semi-automated assembly system and constructed 124 silicon microstrip modules so far for the ATLAS SCT barrel. This article describes the assembly procedure, evaluations of precisions and the module survey results. A precision of B2 mm is achievable with this assembly system. r 2003 Elsevier B.V.

ABSTRACT - Vermicomposting with pomegranate pulp can not only prevent pollution of the environment but can also create jobs, generate added value and prevent the waste of energy and the country's capital. This factorial experiment was conducted in a completely randomized design. The first factor (a) in two levels contained neutralized pomegranate pulp with lime and non-neutralized pulp. The sec...
Background and purpose: Pulp stones are calcified masses in the pulp chamber or root canals. Cone-beam computed tomography (CBCT) can identify crown and root anatomy and also detect calcifications which may help to achieve a better diagnosis. The goal of this study was to determine the frequency of pulp stones in CBCT images. Materials and methods: In this cross-sectional study, 500 CBCT image...
