A Method for the Not-Yet-Seen and the Becoming-coming: Thinking focus group with Deleuze

Often, the research process is hidden under the dominant product, making all decisions, from the research question to the chosen method and theory, seem obvious in retrospect. Consequently, this paper has two tightly intertwined aims: to elucidate the research process of the study on which it is based; and to explore and discuss what this process temporally produced, namely, a focus group intervie

Trajectory-based proofs for sampled-data extremum seeking control

Extremum seeking of nonlinear systems based on a sampled-data control law is revisited. It is established that under some generic assumptions, semi-global practical asymptotically stable convergence to an extremum can be achieved. To this end, trajectory-based arguments are employed, by contrast with Lyapunov-function-type approaches in the existing literature. The proof is simpler and more straig

Simulations of Cryogenic Cavitation of Low Temperature Fluids with Thermodynamics Effects

Cavitation in cryogenic liquids is widely present in contemporary science. In the current study, we re-examine a previously validated acoustic cavitation model which was developed for a gas bubble in liquid water. Furthermore, simulations of cryogenic fluids including the thermal effect, the effect of acoustic pressure amplitude and the frequency of sound field on the bubble dynamics are presented

Is anti-corruption an imperialist plot? Transparency International and development assistance

Over the last decade the anti-corruption movement, led by the Berlin-based NGO Transparency International (TI), as grown to include 90 affiliates throughout the world. While pursuing laudable goals to raise awareness about corruption, promulgate and enforce anti-corruption conventions, pursue anti-corruption projects and embarrass corrupt governments thorugh its Corruption Perception Index and Bri

On leukocyte recruitment in colonic ischemia-reperfusion

Leukocyte recruitment is a rate-limiting step in inflammatory disease. Tissue accumulation of leukocytes is a multi-step process comprising leukocyte rolling, adhesion and transmigration across the vascular endothelium. The aim of this thesis was to investigate the mechanisms underlying ischemia-reperfusion (I/R)-induced leukocyte-endothelial cell interactions in the colon. For this purpose, intra

Heat release in the end-gas prior to knock in lean, rich and stochiometric mixtures with and without EGR

SI Engine knock is caused by autoignition in the unburnt part of the mixture (end-gas) ahead of the propagating flame. Autoignition of the end-gas occurs when the temperature and pressure exceeds a critical limit when comparatively slow reactions - releasing moderate amounts of heat - transform into ignition and rapid heat release. In this paper the difference in the heat released in the end-gas
