Automatic identification and localization of cartographic objects in aerial and satellite images have gained increasing attention in recent years in digital photogrammetry and remote sensing. Although the automatic extraction of man made objects in essence is still an unresolved issue, the man made objects can be extracted from aerial photos and satellite images. Recently, the high-resolution s...

BACKGROUND AND AIM: Needlestick (NS) injuries are one of the most important subjects in the dental field which can cause so many dangerous blood-borne diseases. The aim of this study was to evaluate the prevalence, knowledge, and practice of dentists and their assistants about exposure to sharp contaminated instruments in Kerman, Iran, in 2012. METHODS: In this cross-sectional study, self-admin...

We introduce an efficient technique for computing Casimir energies and forces between objects of arbitrarily complex 3D geometries. In contrast to other recently developed methods, our technique easily handles nonspheroidal, nonaxisymmetric objects, and objects with sharp corners. Using our new technique, we obtain the first predictions of Casimir interactions in a number of experimentally rele...

Background: Sharp injury is a penetrating cut wound from needle or other sharp object which may additionally bring in contacting with blood body fluids of patients who be having an infectious disease. Every year, more than half million health care workers encounter stick that leads exposure to dangerous borne pathogens. This study was conducted assess the magnitude and contributing factors amon...

purpose : the goal of this study was evaluation of the incidence rate of posttraumatic endophthalmitis, its clinical features and probable risk factors in repaired open globe injuries. methods : in this retrospective case series, surgical and medical records of 600 patients with open globe injury were reviewed. patients who underwent primary repair (as soon as possible) in khatam-al-anbia eye h...

BACKGROUND In patients aged 1-34 years, injury is the leading cause of mortality, disability and health care costs. Two to 3% of Level I trauma patients have peripheral nerve injury (PNI). METHODS Data were collected from the Iran National Trauma Registry database, compiled according to the International Classification of Diseases, 9th revision (ICD9) codes, from August 1999 to February 2004....

An unmet need is to develop covert barcodes that can be used to track-trace objects, and authenticate documents. This paper describes a new nanoparticle-based covert barcode system, in which a selected panel of solid-to-liquid phase change nanoparticles with discrete and sharp melting peaks is added in a variety of objects such as explosive derivative, drug, polymer, and ink. This method has hi...
