We report on the passivation properties of molecularly modified, oxide-free Si(111) surfaces. The reaction of 1-alcohol with the H-passivated Si(111) surface can follow two possible paths, nucleophilic substitution (SN) and radical chain reaction (RCR), depending on adsorption conditions. Moderate heating leads to the SN reaction, whereas with UV irradiation RCR dominates, with SN as a secondar...

Course-based undergraduate research experiences (CUREs) have been identified as a promising vehicle to broaden novices' participation in authentic scientific opportunities. While recent studies in the bioeducation literature have focused on the influence of CUREs on cognitive and non-cognitive student outcomes (e.g., attitudes and motivation, science process skills development), few investigati...

Criado no Canadá em 1977 e implantado Brasil 2005, o Rugby Cadeira de Rodas (RCR) é um esporte popular entre indivíduos com tetraplegia. A modalidade proporciona a inclusão pessoas lesão medular cervical, que dificilmente se enquadram nos fatores classificação esportiva outros esportes adaptados. Nesta revisão sistemática possível encontrar planejamento estratégico identificação risco atletas d...

Static rankings of papers play a key role in the academic search setting. Many features are commonly used in the literature to produce such rankings, some examples are citationbased metrics, distinct applications of PageRank, among others. More recently, learning to rank techniques have been successfully applied to combine sets of features producing effective results. In this work, we propose t...

Rotator cuff tears are a common cause of shoulder pain and dysfunction that affect all kinds of people, from sedentary individuals to elite athletes. Surgical repair of rotator cuff tears aims to re-establish the shoulder’s normal anatomical structure with restoration of pain-free motion, strength, and function. Rotator cuff repair (RCR) has evolved from an all-open procedure to an arthroscopic...

Informed by the reserve capacity model, we examined pathways between socioeconomic status (SES) and internalizing symptoms (IS) in 1119 Chilean 10-year-olds. Mediators included parental disciplinary style and reserve capacity resources (RCR), namely home environment, parent-child engagement, and self-esteem, and conduct problems. Using structural equation modeling, the model was stratified by g...

We describe the summative assessment of role-play scenarios that we previously developed to teach central topics in the responsible conduct of research (RCR) to graduate students in science and engineering. Interviews with role-play participants, with participants in a case discussion training session, and with untrained students suggested that role-playing might promote a deeper appreciation o...
