A massive pleural-based tumour: The challenge of diagnosis

AbstractLiposarcomas of the mediastinum and chest wall have been previously described; however, primary pleural liposarcoma is extremely rare.We report an exceedingly rare case of a well-differentiated sclerosing pleural liposarcoma in a 47-year-old male that was resected. We emphasise the importance of careful inspection of the origin of these tumours to allow accurate diagnosis

Surface Debye Temperature Measurement with Reflection High-Energy Electron Diffraction

Measurement of the surface mean-square atomic vibrational amplitude, or equivalently the surface Debye temperature, with reflection high-energy electron diffraction is discussed. Low-index surfaces of lead are used as examples. Particular details are given about the temperature-dependent diffraction pattern of Pb(100) in the Debye-Waller region. The use of reflection high-energy electron diffraction for measurement of the substrate surface temperature in thin-film deposition chambers is suggested. © 1996 American Institute of Physics

Solutions of Some Difference Equations Systems and Periodicity

In this article, analysis and investigation have been conducted on the periodic nature as well as the type of the solutions of the subsequent schemes of rational difference equations with a nonzero real numbers initial conditions

Temperature Dependence of Step Density on Vicinal Pb(111)

The temperature dependence of step density on the vicinal Pb(111) surface is investigated using reflection high-energy electron diffraction. When the temperature is increased from 323 to 590 K. the average terrace width and the average string length at the step edge decrease from 85±25 to 37±16 Å and from 220±33 to 25±8 Å, respectively. Thermal step collapse on the Pb(111) surface near its bulk melting temperature is not observed. Above 530±7 K, the change in the string length at the step edge with temperature becomes small, and the intensity of the (00) beam is significantly decreased. We conclude that partial step melting at the step edge occurs at the surface above 530±7 K

Connexin 26 (GJB2) mutation in KID syndrome: An Egyptian patient

Keratitis ± ichthyosis ± deafness (KID) syndrome is a rare disorder characterized by the occurrence of localized erythematous scaly skin lesions, severe bilateral keratitis, and sensorineural deafness. Other ocular manifestations include corneal epithelial defects and scarring, whichcause progressive decline of visual acuity and may eventually lead to blindness. To our knowledge, few cases have been reported worldwide and none were reported from the Middle East Arab countries. Here we report the first Egyptian patient with this syndrome

Water-Food-Energy Nexus in the Nile River Basin

This is the final version of the poster. Available from the Dresden Nexus Conference via the link in this recordThe Nile - a transboundary river • 11 riparian countries and home for about 250 million people • Rapid population, economic and urbanization growth are projected • Basin-wide planned development can result in regional cooperation or trigger conflicts • The nexus approach is relevant for addressing broader interdependency and managing interlinked resources in a holistic manne
