In this paper, we address a two-echelon humanitarian logistics network design problem involving multiple central warehouses (CWs) and local distribution centers (LDCs) and develop a novel two-stage scenariobased possibilistic-stochastic programming (SBPSP) approach. The research is motivated by the urgent need for designing a relief network in Tehran in preparation for potential earthquakes to ...

PURPOSE There have been few prospective studies evaluating the results of nonsurgical treatment of a well-defined patient cohort with symptomatic basal joint osteoarthritis of the thumb. This prospective study uses a validated outcome instrument to examine the effectiveness of a single steroid injection and 3 weeks of splinting in patients with osteoarthritis in Eaton stages 1 to 4 with a minim...

Although acupuncture is gaining popularity for the treatment of nonspecific pain, the immediate analgesic effect of acupuncture has never been reviewed. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) on disease-related pain to critically evaluate the immediate effect of acupuncture for pain relief. The PubMed and Cochrane Central Register of Controlled...

This article examines the frequently cited argument that coordination issues in humanitarian relief can be addressed more effectively with greater centralized authority and argues for a new conceptualization of aid delivery. The former position suggests a hierarchical, top-down view of the humanitarian relief theater, while this analysis contends that the relief implementation structure may be ...

Pain originating from ophthalmic disease has been well documented. A series of patients presenting with eye or periorbital pain attributed to cervical region dysfunction were diagnosed and treated with injections of subcutaneous lidocaine followed by triamcinolone acetonide. Twelve patients, 11 women and 1 man, ranging in age from 20 to 82 years had an evaluation including a complete eye examin...

Conventional wisdom holds that the southern Appalachian Mountains have not experienced a significant phase of tectonic forcing for >200 myr; yet, they share many characteristics with tectonically active settings, including locally high topographic relief, steep slopes, incised river gorges, and frequent mass-wasting events. Two competing hypotheses are commonly used to explain their modern topo...

INTRODUCTION Use of Selective Nerve Root Block (SNRB) in lumbar region to relieve radicular pain along the course of a particular nerve is being practiced in the recent past. We observed and tabulated therapeutic outcomes of this procedure in management of radiculopathy induced by a prolapsed disc affecting a particular lumbar nerve root. METHODS 40 patients with various grades of disc prolap...

Image intensity variations can result from several di erent object surface e ects, including shading from 3-dimensional relief of the object, or paint on the surface itself. An essential problem in vision, which people solve naturally, is to attribute the proper physical cause, e.g. surface relief or paint, to an observed image. We addressed this problem with an approach combining psychophysica...
