The methods used for disaster victim identification is comparative postmortem profiling of dental and fingerprint data. Twelve dental concordant features are normally required for dental identification. The radiographic image of dental amalgam restorations has been shown to be highly significant for identification purposes. The aim of this study was to investigate the radiological morphology of...

OBJECTIVE (1) To determine the accuracy of accident and emergency (A&E) doctors' diagnosis of radio-opaque ureteric calculi on plain abdominal radiographs; (2) to study the predictive value of haematuria with a history suggestive of ureteric colic. DESIGN A prospective study of all patients seen in a three month period with a provisional diagnosis of ureteric colic. Intravenous urography (IVU...

A well-defined peak was obtained in the same zone of the 2 region in a dose-dependent fashion. Appearance on AGE was unaffected by the additions (Fig. 1). Iopamidol diluted in CZE buffer solution displayed an absorbance maximum of 242 nm as described previously (2 ). The absorbance of iopamidol at 214 nm was 75% of the peak value, accounting for its interference in the CZE analysis. Interferenc...

OBJECTIVES To study the pattern of ingestion of radio-opaque foreign bodies in children and to ascertain the average transit time to passage per rectum in order to rationalise future management. METHODS This prospective study consisted of 100 children under the age of 14 years, presenting to the accident and emergency department of the Royal Aberdeen Children's Hospital having ingested a radi...

BACKGROUND/AIM Functional constipation (FC) and constipation-predominant IBS (C-IBS) are two main subtypes of constipation. Using radio-opaque markers is an easy and cost effective method to measure colonic transit time (CTT). We designed this study to compare the CTT between these two groups of constipated patients. METHODS Patients with chronic constipation of no organic etiology were class...

To develop skills sufficient for hearing preservation cochlear implant surgery, surgeons need to perform several electrode insertion trials in ex vivo temporal bones, thereby consuming relatively expensive electrode carriers. The objectives of this study were to evaluate the insertion characteristics of cochlear electrodes in a plastic scala tympani model and to fabricate radio opaque polymer f...

In this paper we investigate (in)security aspects of Automatic Dependent Surveillance-Broadcast (ADS-B) protocol. ADS-B is intended to be widely deployed in Air Traffic Management (ATM) Surveillance systems by 2020. One of the goals of ADS-B is to increase safety of air traffic. While the security of ADS-B was previously questioned, in this paper we demonstrate that attacks are both easy and pr...

Endangered smalltooth sawfish (Pristis pectinata) were opportunistically sampled in south Florida and aged by counting opaque bands in sectioned vertebrae (n=15). Small sample size precluded traditional age verification, but fish collected in spring and summer had translucent vertebrae margins, while fish collected in winter had opaque margins. Trends in Sr:Ca measured across vertebrae with las...
