Sustainable development as a driver for educational innovation in engineering school: the case of UniLaSalle

ABSTRACT

The potential relationships between innovation and sustainability processes, in engineering education, is neither obvious nor simple, especially when innovation, generally speaking, is promoted regardless of sustainability. We used UniLaSalle (In January 2016, the ‘Institut Polytechnique LaSalle Beauvais’, a French engineering school, merged with another higher education engineering school (ESITPA, Rouen). Both campuses (Beauvais and Rouen) have a common name: UniLaSalle (www.unilasalle.fr). As the interview began during 2015, this article only describes the situation of the Beauvais campus.) as a ‘living Lab’ to identify and analyse the reasons for the integration of innovation and Sustainable Development (SD) in training programmes. The aim is to explore, in a perception and reflective approach, how SD can be understood as a driver for specific innovation attitudes in higher education engineering school. This paper adopts an empirical approach based on a qualitative study, using NVivo 9 software to analyse non-numerical data. Our research suggests that SD can be a structural driver for innovation if it is integrated in a transdisciplinarity approach and not just as a discipline per se.     

试析变压器节能增效的措施

单台变压器运行时，为使效率最高，其负荷的大小必须在一定的范围内；多台变压器并联运行时，为使效率最高，要根据负荷的大小及变化情况确定变压器运行的台数，这样才能做到使变压器经济运行。针对变压器的实际使用情况，提出了具体的节能增效的措施，并进行了相应的理论分析。

多药马兜铃亚属的分类修订

多药马兜钤亚属是马兜铃属目前已知3个亚属中最小的一个亚属，约9种，其中8种产于热带 非洲，1种产于热带亚洲(马来西亚)。  本工作从经典分类学角度对该亚属的系统进行了探讨，首次利用花药数目及其排列方式将其划分为三个组，并对其中所含的种类进行了分类学处理，本文承认9种及3个新异名。     

Construction and operation of a microrobot based on magnetotactic bacteria in a microfluidic chip

Magnetotactic bacteria (MTB) are capable of swimming along magnetic field lines. This unique feature renders them suitable in the development of magnetic-guided, auto-propelled microrobots to serve in target molecule separation and detection, drug delivery, or target cell screening in a microfluidic chip. The biotechnology to couple these bacteria with functional loads to form microrobots is the critical point in its application. Although an immunoreaction approach to attach functional loads to intact MTB was suggested, details on its realization were hardly mentioned. In the current paper, MTB-microrobots were constructed by attaching 2 μm diameter microbeads to marine magnetotactic ovoid MO-1 cells through immunoreactions. These microrobots were controlled using a special control and tracking system. Experimental results prove that the attachment efficiency can be improved to ∼30% via an immunoreaction. The motility of the bacteria attached with different number of loads was also assessed. The results show that MTB can transport one load at a velocity of ∼21 μm/s and still move and survive for over 30 min. The control and tracking system is fully capable of directing and monitoring the movement of the MTB-microrobots. The rotating magnetic fields can stop the microrobots by trapping them as they swim within a circular field with a controllable size. The system has potential use in chemical analyses and medical diagnoses using biochips as well as in nano/microscale transport.     

供应商和客户参与技术创新对创新绩效的影响

以广东省电子信息行业的286家企业为研究对象,探讨了供应商与客户参与技术创新对企业创新绩效影响,以及技术复杂性在供应商与客户参与技术创新和创新绩效关系中的调节效应。结果表明,供应商参与技术创新和客户参与技术创新对创新绩效均有显著的正向影响,技术复杂性对供应商参与技术创新与创新绩效间关系有显著的调节作用,但是对客户参与技术创新与创新绩效间关系的调节作用不显著。
