In the present study, water-oil flow patterns and slug hydrodynamics were experimentally studied in square glass microchannels with various hydraulic diameters (Dh = 600 µm, 400 µm, 200 µm). The aqueous phase is the continuous phase while the organic phase is the dispersed phase. The ranges of flow rates of the continuous phase and the dispersed phase are 0-200 ml/h and 0-12 ml/h, 0-120 ml/h and 0
The chapter describes five examples of dedicated faculty development trajectories for educational leadership in research-intensive universities, focusing on their nature and effects. After discussing and elaborating on the concept of ‘educational leadership’, the chapter portrays and compares professional development trajectories for educational leadership in five research-intensive universities:
A certain "star-product" formalism in scattering theory as developed by Redheffer is shown to also be naturally applicable to discrete-time linear least-squares estimation problems. The formalism seems to provide a nice way of handling some of the well-known algebraic complications of the discrete-time case, e.g., the distinctions between time and measurement updates, predicted and filtered estima
Computers and digital instruments change the way we think about ourselves and other people, demonstrated by an example with a girl who imagined that she had a computer in her brain where she could click on “Music” in the menu to hear music. This chapter argues that good music technology should allow play and unpredictable events and support a balance between challenge and ability. Digital instrume
The future of nations and nationalism appears to many to be more uncertain than ever in view of the growing interdependence of the planet. The question of whether globalization heralds the end of nationalism cannot be answered properly without distinguishing between nation and state. In the case of the state, the question is whether states can preserve their sovereignty intact in an age when polit
This paper analyses optimal subband beamforming performance mainly aimed at speech enhancement and acoustic echo suppression for personal communication devices, personal computers and wireless cellular telephones. The focus is on theoretical limits of finite impulse response (FIR) beamformers for spatially spread sources in the array near-field. Performance of the Wiener solution is compared to th
While imaging optically dense media such as atomizing sprays, the multiple light scattering induces image artifacts and blurring effects which limit visibility.Therefore, extracting quantitative spray information such as droplet size and concentration from qualitative images becomes very challenging. However, multiple scattering effects can be efficiently addressed by means of the SLIPI (Structure
In this work, we utilize classical polymer density functional theory (DFT) to study gelation in systems containing colloidal particles onto which polymers are grafted. The solution conditions are such that the corresponding bulk system displays a lower critical solution temperature (LCST). We specifically compare our predictions with experimental results by Shay et al. (J. Rheol. 2001, 45, 913-927
Combinations of genetic and environmental factors contribute to the pathogenesis of type 2 diabetes (T2D); however, our knowledge of the molecular mechanisms by which these factors trigger diabetes is still limited. While genome-wide association studies have identified and characterized more than 60 genomic loci associated with T2D, recent methylome charts and reference regulatory maps obtained fr
BACKGROUND: Increased intraocular pressure (IOP) has been shown to be one of the most important risk factors for developing glaucoma. Yet it has not been clearly demonstrated that IOP-lowering treatment can reduce the incidence of glaucoma damage in patients with ocular hypertension. The aim of the current paper was to report the results of a long-term study addressing this very problem.METHODS: W
Several authors have reported problems on service courses in basic probability and statistics: students may lack motivation, find the theory difficult or boring, others see no applications for the results. To remedy these problems we have developed a learning environment where two important components are applied problems and use of technology. However, the mere existence of applied problems and t
BACKGROUND: After more than 4 decades experience of total knee arthroplasty (TKA), there is still a group of patients who are not satisfied with the outcome. In spite of the improvement of many aspects around the procedure, for unexplainable reasons, patient dissatisfaction is still approximately the same. We conducted this study to analyze correlations between preoperative psychological aspects a
Subjective experience has often taken center stage in debates between competing conceptual theories of the mind. This is also a central object of concern in the empirical domain, and especially in the search for the neural correlates of consciousness (NCCs). By now, most of the competing conceptual theories of consciousness have become aligned with distinct hypotheses about the NCCs. These hypothe
