a strategy employing moderate hypothermia for the replacement of the aortic arch is proposed to avoid the complications of profound hypothermic circulatory arrest. two patients underwent the complete replacement of the aortic arch using three pumps - for the brain, thoracoabdominal aorta, and heart, respectively. there were no complications and the patients were extubated uneventfully. the meth...

the objectives of this research were to study the varieties and relationships of yield and quality traits under two harvesting management procedures concerning forage dry matter (dm yield) and 5 quality traits such as dry matter digestibility (dmd%), water soluble carbohydrates (wsc%), crude protein (cp%), acid detergent fibre (adf%) and total ash in tall wheatgrass (agropyron elongatum). in th...

context the current literature suggests that minimally invasive surgery is associated with faster recovery and less morbidity than open surgery. parenchyma-sparing pancreatectomy is minimally invasive surgery, including enucleation, inferior head pancreatectomy, spleen-preserving distal pancreatectomy, and central pancreatectomy, combined pancreatectomy such as inferior head pancreatectomy plus...

multiple objective programming (mop) problems have become famous among many researchers due to more practical and realistic implementations. there have been a lot of methods proposed especially during the past four decades. in this paper, we develop a new algorithm based on a new approach to solve mop problems by starting from a utopian point (which is usually infeasible) and moving towards the...

Since its inception, Audiology has been concerned with hearing aid selection and the interaction of the hearing impaired person and amplification . The classic work of Watson and Knudsen (1) and Lybarger (2) suggests a long clinical interest in prescribing parameters for hearing aids according to audiometric measurements . In the early days, prescriptive procedures were neglected due to technol...
