Zhao, J. (author), Li, J. (author), Yan, H. (author), Zheng, L. (author), Dai, Z. (author)Analysis on the hydrologic characteristics of the main stream of the Yangtze River and Poyang Lake were studied to discuss the water exchange between the main stream of the Yangtze River and Poyang Lake before and after the operation of Three Gorges Reservoir, as well as in the typical dry year of 2006. The annual runoff distribution for dry...journal article 2011

Zhao, G. (author), Visser, P.J. (author), Vrijling, J.K. (author)This paper describes the hydrodynamic erosion process of undisturbed clay due to the turbulent flow, based on theoretical analysis and experimental results. The undisturbed clay has the unique and complicated characteristics of cohesive force among clay particles, which are highly different from disturbed clay and non-cohesive sand. Based on...conference paper 2011

Guo, Renzhong (author), Li, Lin (author), He, Biao (author), Luo, Ping (author), Ying, Shen (author), Zhao, Zhigang (author), Jiang, Renrong (author)A rapid urban growth in China urges to extend land use to land space use in three dimensions due to limited land resource in cities. 3D cadastre is emerging as an effective means to support such a demands for using urban land in a way of three dimensions. Shenzhen, located in the south-eastern coastal region of China, as one of the most...conference paper 2011

(author), Daran, J.M. (author), Heijnen, J.J. (author), Van Gulik, W.M. (author)Background In microbial production of non-catabolic products such as antibiotics a loss of production capacity upon long-term cultivation (for example chemostat), a phenomenon called strain degeneration, is often observed. In this study a systems biology approach, monitoring changes from gene to produced flux, was used to study degeneration of...journal article 2011

Zhao, Q. (author), Young, I.T. (author), De Jong, J.G.S. (author)We have constructed a mathematical model to analyze the photon efficiency of frequency-domain fluorescence lifetime imaging microscopy (FLIM). The power of the light source needed for illumination in a FLIM system and the signal-to-noise ratio of the detector have led us to a photon “budget.” These measures are relevant to many fluorescence...journal article 2011

Su, J.F. (author), Wang, X.Y (author), Huang, Z. (author), Zhao, Y.H. (author), Yuan, X.Y. (author)Microencapsulated phase change materials (microPCMs) have been widely applied in solid matrix as thermal-storage or temperature-controlling functional composites. The thermal conductivity of these microPCMs/matrix composites is an important property need to be considered. In this study, a series of microPCMs have been fabricated using the in...journal article 2011

Santofimia, M.J. (author), Zhao, L. (author), Sietsma, J. (author)The application of the quenching and partitioning (Q&P) process in steels involves a microstructural evolution that is more complex than just the formation of martensite followed by carbon partitioning from martensite to austenite. Examples of this complexity are the formation of epitaxial ferrite during the first quenching step and the...journal article 2011

Zhao, L. (author)In this thesis, we present an automatic polyp detection approach that integrates knowledge from flow visualization techniques. Our primary goal was to compute additional characteristic polyp features that improve the CAD performance of existing polyp detection approaches by eliminating found false-positive polyp candidates. We found that surface...doctoral thesis 2011

Santofimia, Maria Jesus (author), Zhao, L. (author), Petrov, R.H. (author), Kwakernaak, C. (author), Sloof, W.G. (author), Sietsma, J. (author)This paper presents a detailed characterization of the microstructural development of a new quenching and partitioning (Q&P) steel. Q&P treatments, starting from full austenitization, were applied to the developed steel, leading to microstructures containing volume fractions of retained austenite of up to 0.15. The austenite was...journal article 2011

(author)The in vivo flux through the oxidative branch of the pentose phosphate pathway (oxPPP) in Penicillium chrysogenum was determined during growth in glucose/ethanol carbon-limited chemostat cultures, at the same growth rate. Non-stationary 13C flux analysis was used to measure the oxPPP flux. A nearly constant oxPPP flux was found for all glucose...journal article 2010

Zhao, L.H. (author), Andersson, H.I. (author), Gillissen, J.J.J. (author)This letter reports on the pronounced turbulence modulations and the accompanying drag reduction observed in a two-way coupled simulation of particle-laden channel flow. The present results support the view that drag reduction can be achieved not only by means of polymeric or fiber additives but also with spherical particles.journal article 2010
