Molecular diffusion analysis of dynamic blood flow and plasma separation driven by self-powered microfluidic devices     

Sung Oh Woo  Myungkeun Oh  Kyle Nietfeld  Bailey Boehler  Yongki Choi 《Biomicrofluidics》2021,15(3)

Integration of microfluidic devices with pressure-driven, self-powered fluid flow propulsion methods has provided a very effective solution for on-chip, droplet blood testing applications. However, precise understanding of the physical process governing fluid dynamics in polydimethylsiloxane (PDMS)-based microfluidic devices remains unclear. Here, we propose a pressure-driven diffusion model using Fick''s law and the ideal gas law, the results of which agree well with the experimental fluid dynamics observed in our vacuum pocket-assisted, self-powered microfluidic devices. Notably, this model enables us to precisely tune the flow rate by adjusting two geometrical parameters of the vacuum pocket. By linking the self-powered fluid flow propulsion method to the sedimentation, we also show that direct plasma separation from a drop of whole blood can be achieved using only a simple construction without the need for external power sources, connectors, or a complex operational procedure. Finally, the potential of the vacuum pocket, along with a removable vacuum battery to be integrated with non-PDMS microfluidic devices to drive and control the fluid flow, is demonstrated.  相似文献   

Idea generation in biomedical engineering courses using Design Heuristics

ABSTRACT

With increasing demand for improved medical equipment and healthcare, next-generation biomedical engineers need strong design skills. Equipping biomedical engineering students with tools for idea generation and development can increase student design success. Design Heuristics are an ideation tool developed through empirical studies of product designs. While identified in the mechanical engineering space, Design Heuristics may be applicable in biomedical engineering design. In our study, we implemented a Design Heuristics session during upper-level undergraduate and first-year graduate biomedical engineering design courses. We examined the applicability of Design Heuristics within individual and team concept generation contexts. The findings demonstrated that biomedical engineering students were able to use Design Heuristics to generate multiple concepts, and that initial concepts produced using Design Heuristics were carried over into final team design. The results support the applicability of Design Heuristics to student idea generation in biomedical engineering design.  相似文献

‘Nowhere that fits’: the dilemmas of school choice for parents of children with Statements of special educational needs (SEN) in England     

Meanu Bajwa‐Patel  Cristina Devecchi 《Support for Learning》2014,29(2):117-135

Giving parents a choice with regard to their children's education has been central to the political discourse of school reform at least since the 1988 Education Reform Act (ERA). With regard to children with a Statement of special educational needs (SSEN), a plethora of policies and laws have given parents the right not only to choose a school, but also to appeal to decisions in the best interest of their children. Yet, despite the discourse of school choice, the implementation and practice of such reforms is neither assured nor simple. Participants in this study indicated that they have little choice of suitable provision and are having to compromise either the academic or the social aspects of their child's schooling. This article argues that for many parents whose children have a Statement of SEN, the choice of a school is often a dilemma, as ‘nowhere seems to fit’.  相似文献   

What Lies between the Religious and the Secular?: Education beyond the Human     

Yong‐Seok Seo 《Journal of Philosophy of Education》2014,48(1):86-99

The current age is characterised by many as secular, and a source of such a characterisation can be found in the Nietzschean claim that thoughts about there being some ultimate reality have to be jettisoned, and human existence and the world need to be embraced as they are. That claim is renewed by some secular thinkers who insist that education has to be reconceived in ways congenial to the new age. It is argued that central to their logic is the dichotomy between the religious and the secular or the otherworldly and the earthly, and that this dichotomy is simplistic as well as problematic. As an alternative to the ‘two worlds’ view, the ‘two aspects’ view is suggested, with an interpretation of reality that the noumenon––the non‐human––has to be taken in the negative sense. Against secularising the domain of education, it is indicated that there still remains a place for education to occupy between the two poles of religiousness and secularity.  相似文献   

The Effects of Self‐ and Peer‐Monitoring in Social Studies Performance of Students with Learning Disabilities and Low Achieving Students          下载免费PDF全文

Woori Kim  Min Wook Ok  Yongseok Yoo 《Learning disabilities research & practice》2018,33(2):87-98

This study employed group randomized trials to investigate the effects of self‐ and peer‐monitoring on the academic vocabulary and content knowledge of students with learning disabilities and low achieving students in social studies. Fourth grade students were randomly assigned to either treatment or control groups on a class level. Results indicated that there was a significant interaction effect between the intervention and students’ pretest scores on academic vocabulary acquisition; the intervention was more effective for students with lower scores in the pretest than those with higher scores. In addition, there was a significant intervention effect on content knowledge acquisition; the effect size of the growth of the treatment group on the content knowledge test was significantly larger than that of the comparison group. Teacher interviews also revealed that teachers viewed the intervention positively. Implications for practice and suggestions for future research are discussed.  相似文献   

中国武术节与中国地域武术的共生及协同发展研究     

李源  闫民  梁勤超 《首都体育学院学报》2020,(2):146-150

运用文献研究法等,从共生理论视角,分析中国武术节与中国地域武术的共生关系及协同发展路径。在当前举办的中国武术节中,存在3个共生单元:武术节、主办方与地域武术,这三者之间形成了3种不同的共生关系。其中:中国武术节与主办方、中国武术节与中国地域武术形成了"间歇共生组织"和"对称互惠共生行为";而中国地域武术与主办方则形成了"间歇共生组织"和"非对称互惠共生行为"。要实现中国武术节与中国地域武术之间的协同发展,需加强中国武术节节庆制度建设;深化中国武术节与中国地域武术的关联;促进中国地域武术的传承与发展。  相似文献   

A Moment of Letting Go: Iris Murdoch and the Morally Transformative Process of Unselfing          下载免费PDF全文

ANNA‐LOVA OLSSON 《Journal of Philosophy of Education》2018,52(1):163-177

Higher education as a personal, intellectual and moral cultivation is a longstanding ideal that is constantly challenged by the view that education is merely the development of specific skills for vocational and personal success. Much research argues that the latter understanding makes education a technical affair that creates an egocentric emphasis on the individual students’ ambitions and desires. This article joins in the defence of the former ideal by enquiring into the moral dimensions of education. This is done by turning to Iris Murdoch's idea of moral transformation, with a specific focus on the idea of unselfing. The main argument is that unselfing is a transformative process characterised by a growing attunement to the surrounding world, and the interconnectedness of goal and process is emphasised. Also, to gain a deeper understanding of what unselfing entails I turn to the idea of attention. It is understood as having a specific direction, outward from the egocentric, and as enabling unselfing. The article concludes by suggesting that unselfing can offer a challenge to (higher) education as it entails a moment of letting go of plans and narratives, and of surrendering to the influence of an existence that exceeds the individual. This moment is of relevance to education as it is crucial to the possibility of growing as a moral being as it cultivates a moral manner of relating to others.  相似文献
