This paper focuses on the problem of how to allow a source to send a message without revealing its physical location and proposes an anti-localization routing protocol, ALAR, to achieve anonymous delivery in Delay/Disruption Tolerant Networks. The objectives of ALAR are to minimize the probability of a data source being localized and to maximize the destination’s probability of receiving the me...

Objectives: We present our 3 years experience with alar batten grafts, using a modified technique, for non-iatrogenic nasal valve/alar

Maxillary canines affect the smile and facial esthetics providing upper lip alar base support. This article presents case report of skeletal class I malocclusion with Angle’s III (Right) subdivision impacted left maxillary canine poor prognosis for traction which was managed successfully a combined surgical orthodontic approach. The diagnosis impaction done through Orthopantogram, intra-oral pe...

BACKGROUND AND PURPOSE Evaluation of alar traumatic injuries by using MR imaging is frequently performed. This study investigates the variability of morphology and signal intensity of alar ligaments in healthy volunteers so that pathology can be more accurately defined. MATERIALS AND METHODS Fifty healthy volunteers were examined on a 1.5T MR imaging scanner with 2-mm PD-weighted sequences in...

BACKGROUND Alar rim deformities such as retraction, notching, collapse, and asymmetry are common problems in rhinoplasty patients. Although alar rim deformities may be improved through rhinoplasty, this area is prone to late changes because of scarring of the soft triangles and a paucity of native structural support. The purpose of this study was to analyze the effect of alar contour grafts on ...

Activation of dihydrogen by masked dialumenes (Al=Al doubly bonded species) is reported. Reactions of barrelene-type dialumanes, which have the reactivity as masked equivalents of 1,2-diaryldialumenes ArAl=AlAr, with H2 afforded dihydroalumanes ArAlH2 at room temperature (Ar: bulky aryl groups). These dihydroalumanes form hydrogen-bridged dimers [ArHAl(μ-H)]2 in the crystalline state, while a m...

BACKGROUND Reconstruction of nasal alar defects is difficult because of the complex anatomy of the region. A frequent challenge in this area is repair of small cutaneous defects involving the lateral nasal supratip and the superior alar groove. OBSERVATIONS An oblique advancement flap that uses laxity from the nasal sidewall is described. Its benefits and limitations are compared with those o...

This technical report describes a simple and innovative surgical technique for supra-alar sidewall region constriction and supra-alar crease attenuation by cinching technique through intraoral approach.
