As agents of strategic institutional change, entrepreneurs (IEs) draw resources from their structural environment to alter the context in which they are embedded. In this article, we explore IEs mobilize different settings. We distinguish between (positional or free) field and personal resources, all may be material, cultural, social, symbolic political kind. Our review leading case studies ent...

From development up to adulthood, the vertebrate brain is continuously supplied with newborn neurons that integrate into established mature circuits. However, how this process is coordinated during development remains unclear. Using two-photon imaging, GCaMP5 transgenic zebrafish larvae, and sparse electroporation in the larva's optic tectum, we monitored spontaneous and induced activity of lar...

crude glycerol (cg) is an abundantly available and cheap by-product from biodiesel production. value-added applications for cg are highly wanted by industry and several processes such as the use of cg for enhanced oil recovery have been proposed. the aim of this study was to evaluate the sulfide production of sulfate-reducing bacteria (srb) indigenous to oil reservoirs using cg as substrate. th...

There are only few techniques allowing an undisturbed and simultaneous monitoring of two important flow characteristics, i.e. temperature and velocity fields. One of such possibilities appeared when thermochromic liquid crystals became commercially available. Initiated almost 15 years ago technique of simultaneous measurement of temperature and velocity fields (Hiller & Kowalewski 1987) recentl...

Abstract Carbon nanotube (CNT) is one of the most widely used nanomaterials recently. Since it was discovered by Iijima in 1991, its various synthesis methods were being mature past 30 years. The research carbon applications different fields has never stopped. a number researchers have tested excellent properties CNTs, provides an optimistic expectation about CNT future. This review summarizes ...

In the last ten years, laser-based glass micromachining has become a mature technology, which is now out of R&D labs and finally deployed in industry as scalable micro-manufacturing process to produce innovative optics photonics devices. Micro-optics, integrated photonics, optical communication, displays, photonic quantum computing are among fields that looking at this potentially ground-breaki...

In modern computer games market, highly automated testing becomes one of key factors of success. At current stage, industry of computer games is not mature enough for automated testing. The paper describes method of bringing automated quality assurance techniques from more established computer engineering fields to computer game development. Automated acceptance testing framework, based on Pyth...

This paper presents the autonomous table soccer robot KiRo. KiRo provides a competitive challenge for even advanced human players and is well suited as a toy or even as a training partner for professional players. Moreover, the table soccer game represents a demanding testbed for evaluating a multitude of techniques and approaches in the fields of robotics and artificial intelligence. KiRo has ...

Though cloud computing is considered mature for practical application, there is a need for more research. The identified challenges primarily concern client-cloud interaction and cloud interoperability. As to the former one, we highlight the needs of clients, contracting and legal aspects, and missing foundations as necessary fields of investigation. For the latter one clouds are considered to ...
