Caratelli, D. (author), Yarovoy, A. (author)Ground-penetrating radar (GPR) technology finds applications in many areas such as geophysical prospecting, archaeology, civil engineering, environmental engineering, and defence applications as a non-invasive sensing tool [3], [6], [18]. One key component in any GPR system is the receiver/transmitter antenna. Desirable features for GPR antennas...book chapter 2011

Molenbroek, J.F.M. (author), Mantas, J. (author), De Bruin, R. (author)This book addresses the topic of toilet design, but instead of focusing on the typical able bodied user, it takes the various needs and limited abilities of older and/or disabled people as its starting point (human centered design). This follows the principles of ‘Inclusive Design’: designs taking into account the needs of the most challenged,...book 2011

(author), Daran, J.M. (author)The industrial production of penicillin G by Penicillium chrysogenum requires the supplementation of the growth medium with the side chain precursor phenylacetate. The growth of P. chrysogenum with phenylalanine as the sole nitrogen source resulted in the extracellular production of phenylacetate and penicillin G. To analyze this natural pathway...journal article 2011

(author), Daran-Lapujade, P.A.S. (author)Extremely low specific growth rates (below 0.01 h?1) represent a largely unexplored area of microbial physiology. In this study, anaerobic, glucose-limited retentostats were used to analyse physiological and genome-wide transcriptional responses of Saccharomyces cerevisiae to cultivation at near-zero specific growth rates. While quiescence is...journal article 2011

Dunning, A.G. (author), Tolou, N. (author), Herder, J. (author)For many applications in precision engineering, a six degrees of freedom (DoF) compliant stage (CS) with zero stiffness is desirable, to deal with problems like backlash, friction, lubrication, and at the same time, reduce the actuation force. To this end, the compliant stage (also known as compliant mechanism) can be statically balanced with a...journal article 2011

(author)Cultivation methods used to investigate microbial calorie restriction often result in carbon and energy starvation. This study aims to dissect cellular responses to calorie restriction and starvation in Saccharomyces cerevisiae by using retentostat cultivation. In retentostats, cells are continuously supplied with a small, constant carbon and...journal article 2011

Bitenc, M. (author), Lindenbergh, R.C. (author), Khoshelham, K. (author), Van Waarden, A.P. (author)The Dutch coast is characterized by sandy beaches flanked by dunes. Understanding the morphology of the coast is essential for defense against flooding of the hinterland. Because most dramatic changes of the beach and the first dune row happen during storms, it is important to assess the state of the coast immediately after a storm. This is...journal article 2011

Bakker, J.J.W. (author), Zieverink, M.M.P. (author), Kapteijn, F. (author), Moulijn, J.A. (author), Kreutzer, M.T. (author)Segmented flow in standard GC capillary columns, with a heterogeneous Pd catalyst on the walls, gave rapid information about catalytic processes in them. The residence time and conversion was monitored visually, greatly simplifying bench-scale optimization. Examples show the benefits of the elimination of pore diffusion and axial dispersion....journal article 2011

Stallinga, S. (author)A theory of optical trapping at low Numerical Aperture (NA) is presented. The theory offers an analytical description of the competition between the stabilizing gradient and destabilizing scattering force. The trade-off can be characterized by a single dimensionless trapping parameter, which increases with bead size to wavelength ratio ?/?, m,...journal article 2011

(author)Penicillium chrysogenum is widely used as an industrial antibiotic producer, in particular in the synthesis of ß-lactam antibiotics such as penicillins and cephalosporins. In industrial processes, oxalic acid formation leads to reduced product yields. Moreover, precipitation of calcium oxalate complicates product recovery. We observed oxalate...journal article 2011

(author)A self-similar reaction front develops in reactive ion etching when the ions penetrate channels of shallow height h. This relates to the patterning of microchannels using a single-step etching and bonding, as described by Rhee et al. [Lab Chip 5, 102 (2005)] . Experimentally, we report that the front location scales as xf ? ht1/2 and the width...journal article 2011

Voortman, L.M. (author), Stallinga, S. (author), Schoenmakers, R.H.M. (author), Van Vliet, L.J. (author), Rieger, B. (author)Today, the resolution in phase-contrast cryo-electron tomography is for a significant part limited by the contrast transfer function (CTF) of the microscope. The CTF is a function of defocus and thus varies spatially as a result of the tilting of the specimen and the finite specimen thickness. Models that include spatial dependencies have not...journal article 2011
