The seismic performance of hybrid braces composed of steel and shape memory alloy (SMA) was investigated in this paper. Six types of hybrid braces were used, constituted by SMA content of 0, 20, 40, 60, 80, and 100%. A nonlinear dynamic analysis was performed under El Centro earthquake records, with the maximum acceleration of 0.6g and 0.9g. Our results showed that the seismic performance, i.e....

Hepatic arterial vascularization presents great anatomic variability. The vascular configuration described as normal is found in only 55%–75.5% of cases, which means that a large percentage of patients present an anatomic variation. Amongst them, the most frequent variation is the right hepatic artery (RHA), branch of the superior mesenteric artery (SMA). This variation can involve a single rig...

We report a case of acute type A dissection with ischemic enterocolitis due to blood flow insufficiency in the superior mesenteric artery. A 67 year-old man, with medicated ischemic heart disease and hypertension, presented to another hospital with chest pain radiating to the back and epigastrium. Contrast-enhanced computed tomography revealed a type A dissecting aneurysm, that extended from th...

OBJECTIVE To describe the fate of the false lumen remaining in the descending thoracic aorta after extensive primary repair of the thoracic aorta by the modified elephant trunk technique with a stent graft for acute type A aortic dissection, particularly the changes of the false lumen on enhanced CT scanning. METHODS The subjects were 65 consecutive patients who received arch replacement with...

Pancreatic cancer patients with para-aortic lymph node metastasis have a poor prognosis and patients living longer than 3 years are rare. We had a patient with pancreatic cancer who survived for more than 10 years after removal of the para-aortic lymph node metastasis. A 57-year-old woman was diagnosed with pancreatic head cancer and underwent a pancreaticoduodenectomy with subtotal gastric res...

Résumé. Le principe d’un ordonnancement coopératif selon une modélisation multi-agents résulte du rapprochement des domaines de l’Ordonnancement et de l’Intelligence Artificielle Distribuée. Le travail que nous présentons dans ce papier a pour objectif l’étude de l’adéquation des métaheuristiques avancées dans un SMA dans le cadre de la résolution d’un problème d’optimisation bien défini qui es...

background: spinal muscular atrophy (sma) is the second most common lethal autosomal recessive disease. it is a neuromuscular disorder caused by degenerative of lower motor neurons and occasionally bulbar neurons leading to progressive limb paralysis and muscular atrophy. the smn1 gene is recognized as a sma causing gene while naip has been characterized as a modifying factor for the clinical s...

spinal muscular atrophy (sma) is an autosomal recessive neuromuscular disorder characterized by degeneration of spinal cord anterior horn cells, leading to muscular atrophy. sma is clinically classified into three sub-groups based on the age of onset and severity. the majority of patients with sma have homozygous deletions of exons 7 and 8 of the survival motor neuron (smn) gene. the purpose of ...
