the static pull-in instability of beam-type micro-electromechanical systems is theoretically investigated. two engineering cases including cantilever and double cantilever micro-beam are considered. considering the mid-plane stretching as the source of the nonlinearity in the beam behavior, a nonlinear size-dependent euler-bernoulli beam model is used based on a modified couple stress theory, c...

Recently, technology roadmaps have been actively constructed by various organizations such as governments, industry segments, academic societies and companies [1]. While the common basic purpose of these roadmaps is sharing common recognition of the technology among stakeholders, there exists a specific role for each organization. One of the important roles of academic societies is to show the ...

Abstract Background As a novel type of non-coding RNA, circular RNAs (circRNAs) play critical role in the initiation and development various diseases, including cancer. However, exact function circRNAs human cervical cancer remains largely unknown. Methods We identified circRNA signature upregulated between paired adjacent normal tissues. Using two different cohorts GEO database, total six were...

We study the dynamic behaviour of a hybrid system where manufacturing and remanufacturing operations occur simultaneously to produce same serviceable inventory for order fulfilment. Such system, commonly found in photocopier personal computer industries, has received considerable attention literature. However, its performance resulting bullwhip effect, under push pull policies, remain unexplore...

This paper explores the broad issues of why the meaningful use of ICT to engage in deep learning has not been widespread in K-12 schools. We argue a critical reason is the lack of sustainability in the implementation of ICT-enabled pedagogies in schools, arising from a failure to understand the conditions for systemic innovations. We describe the key issues related to sustainability from litera...

Tolerance to +G(z) gravitational stress is reduced when +G(z) stress is preceded by exposure to hypogravity (fractional, 0, or negative G(z)). For example, there is an exaggerated fall in eye-level arterial pressure (ELAP) early on during +G(z) stress (head-up tilt; HUT) when this stress is immediately preceded by -G(z) stress (head-down tilt; HDT), termed the "push-pull effect." The aim of the...

This paper explores the potentially powerful role e-assessment practices can have on culture change in learning and teaching. This paper demonstrates how new e-assessment practices can ‘push back’ through educational institutions. This is done by applying the work of Gibbs and Simpson (2004/5) to e-assessment practices. To illustrate the practical effects of this evidence-based framework, the a...

The materialists pull everything down from the sky and out of the invisible world onto the earth as if they wanted to clench rocks and oak trees in their fists. They grasp them, and stubbornly maintain that the only objects that exist are those that are tangible and comprehensible. They believe that the physical existence of an object is existence itself, and look down smugly on other people — ...
