Computational materials modeling and design has emerged as a vital component of materials research and development in academic, industrial, and national lab settings. In response, US Materials Science and Engineering (MatSE) departments and the federal government recognize the need to incorporate computational training into undergraduate MatSE education. Our faculty team at the University of Illinois at Urbana-Champaign (UIUC) is addressing this growing need with a comprehensive computational component integrated into the MatSE curriculum. Throughout their coursework, undergraduates complete a series of computational modules of progressing complexity, each module modeling the principles taught in its containing course. Computational lectures accompany most modules and further illustrate how computational methods solve real-life science and engineering problems. The computational curriculum is supported by a dedicated teaching assistant who helps with module development, delivers computational lectures, and offers additional office hours. Now, three years since initial implementation, multiple student cohorts have experienced the computational curriculum at all course levels. In this paper, we present new results on the efficacy of the computational curriculum and share more information about our continued efforts to improve the computational modules, lectures, and their integration within the broader MatSE curriculum

Tamponamento cardíaco tardio traumático: análise de cinco casos Traumatic late cardiac tamponade: analysis of five cases

São analisados cinco casos de tamponamento cardíaco tardio traumático. Os pacientes eram masculinos, idade média de 26,2 anos, vítimas de ferimento por arma branca em região precordial, área de Ziedler, sendo admitidos em centro de referência para trauma. Foram classificados pelo índice fisiológico de Ivatury para trauma cardíaco e inicialmente tratados por pleurotomia intercostal e reposição volêmica, com estabilização do quadro hemodinâmico e respiratório. Os pacientes foram readmitidos após intervalo de oito a 24 dias (mediana de 20 dias), agora no serviço de cirurgia torácica de um hospital de referência terciária, com sinais de tamponamento cardíaco. Os exames diagnósticos confirmaram derrame pericárdico com espessamento pericárdico associado a encarceramento de base pulmonar esquerdo em quatro casos, os quais foram abordados por toracotomia póstero-lateral, com realização de pericardiectomia parcial e descorticação pulmonar. Um paciente evoluiu com pericardite purulenta, comprovada por exames complementares, e foi submetido à drenagem pericárdica subxifóidea. Ocorreu arritmia pós-operatória em um paciente; os demais evoluíram sem complicações pós-operatórias ou recidiva do tamponamento.<br>Five traumatic late cardiac tamponade cases were analyzed. All patients were male, mean age was 26.2, victims of thoracic penetrating stabbing wound in the precordial region, Ziedler area, admitted to a trauma reference center. They were classified by the Ivatury physiological index for cardiac trauma. The first treatment approach was intercostal pleurectomy and volemic resuscitation followed by hemodynamic and respiratory recovery. Patients with cardiac tamponade symptoms were re-admitted within an interval from eight to twenty four days (mean 20 days) in a thoracic surgery service of a tertiary reference hospital. Diagnostic exams confirmed thickening and pericardial effusion associated with a left pulmonary base entrapment in four of the cases which were treated by posterolateral thoracotomy, including partial pericardiectomy and pulmonary decortication. One patient was diagnosed with purulent pericarditis by supplementary exams and underwent a subxiphoid pericardial drainage. Postoperative cardiac arrhythmia occurred in one patient but the others did not develop any complications and there were no tamponade recurrent cases
