Professor Emeritus, Institute of Psychiatry, Psychology and Neuroscience, King’s College London, UK, [email protected] In this issue, three papers discuss the issue of the brain drain: of psychiatrists from Egypt and Nigeria, and of nurses from East Africa. They explore the complexities of professional migration and its impact on the health of populations in source and recipient countries; they a...

In Behçet's disease (BD) patients, endovascular repair is a reasonable alternative treatment for aortic aneurysms to avoid postoperative anastomotic pseudoaneurysms. However, there are some complications that may occur after endovascular repair. We herein report the case of a 40-year-old man with active BD developed recurrent aortic pseudoaneurysms at the proximal and distal margins of the sten...

This paper presents investigative results of the energy efficiency of hot water production for sanitary uses by means of gas-fired water heaters with the combustion chamber sealed with respect to the room in single-family houses and multi-story buildings. Additionally, calculations were made of the influence of pre-heating the air for combustion in the chimney and air supply system on the energ...

The hydrothermal vent system is a typical chemosynthetic ecosystem in which microorganisms play essential roles in the geobiochemical cycling. Although it has been well-recognized that the inorganic sulfur compounds are abundant and actively converted through chemosynthetic pathways, the sulfur budget in a hydrothermal vent is poorly characterized due to the complexity of microbial sulfur cycli...

In this talk, we present results from a geophysical investigation at the Chimney Rock Great House using magnetics, electromagnetics, and DC resistivity. Our data is focused on a grid southwest of the Great House, where we use geophysics to detect potential buried walls. These walls may be covered by 1 to 3 m of fill as a result of nearby excavations in the 1920s, and should be approximately 0.5...

While thoracic endovascular aortic repair is an effective treatment option for descending thoracic aorta pathology, it does have limitations. The main limitation is related to the anatomical difficulties when disease involves the aortic arch. A fenestrated, branched aortic stent graft and hybrid operation has been introduced to overcome this limitation, but it is a custom-made device and is tim...

Research on musical instrument design suggests that deliberate constraints can offer new creative experiences to the performer. At times, design constraints are physically embedded in the instrument to limit the interaction possibilities; in other cases the constraints are given by delegating part of the control to the machine. In this paper we propose a case study related to the latter form of...

Low birth weight is associated with exposure to air pollution during pregnancy. The purpose of this study was to evaluate whether null polymorphisms of Glutathione S-transferases (GSTs), specifically GSTM1 and GSTT1 genes in infants or mothers, modify the association between high exposures to household air pollution (HAP) from cooking fires and birth weight. Pregnant women in rural Guatemala we...
