Auslegung von Rührfermentern – Berücksichtigung der nicht‐Newton'schen Eigenschaften von Fermentationslösungen
Authors: Henzler H.‐J.
Published: April 2007

Die Korrelation bzw. Berechnung verfahrenstechnischer Kennwerte für die Auslegung von Fermentern bei nicht‐Newton'schen Lösungen erfolgt in der Regel mit den Auslegungsunterlagen für Newton'sche Flüssigkeiten, wobei für die Viskosität eine repräsentative Viskosität verwendet wird. In der vorliegenden Arbeit werden die verfahrenstechnischen Operationen Leistungseintrag bei laminarer Strömung sowie der Wärmetransport und Stofftransport gasförmig/flüssig bei turbulenter Strömung behandelt, um das bisherige Vorgehen kritisch zu beleuchten. Ausgehend von den Viskositätsfunktionen der strukturviskosen Flüssigkeiten werden dimensionslose Kennzahlen abgeleitet, die zur Beschreibung der verschiedenen Vorgänge erforderlich sind. An Hand der Korrelation experimenteller Ergebnisse aus Labor‐ und Großanlagen (V = 50 – 50000 L) erfolgen anschließend die Gegenüberstellung und die Bewertung der ähnlichkeitstheoretischen Konzepte sowie der Konzepte der repräsentativen Viskosität (des Drehzahl‐ und des Leistungskonzeptes).

Authors: Yu Hao , Zheng Jian‐Bin
Published: April 2007

A copper hexacyanoferrate modified ceramic carbon electrode (CuHCF/CCE) had been prepared by two‐step sol‐gel technique and characterized using electrochemical methods. The resulting modified electrode showed a pair of well‐defined surface waves in the potential range of 0.40 to 1.0 V with the formal potential of 0.682 V (vs. SCE) in 0.050 mol·dm−3 HOAc‐NaOAc buffer containing 0.30 mol·dm−3 KCl. The charge transfer coefficient (α) and charge transfer rate constant (ks) for the modified electrode were calculated. The electrocatalytic activity of this modified electrode to hydrazine was also investigated, and chronoamperometry was exploited to conveniently determine the diffusion coefficient (D) of hydrazine in solution and the catalytic rate constant (kcat). Finally, hydrazine was determined with amperometry using the resulting modified electrode. The calibration plot for hydrazine determination was linear in 3.0×10−6–7.5×10−4 mol·dm−3 with the detection limit of 8.0×10−7 mol·dm−3. This modified electrode had some advantages over the modified film electrodes constructed by the conventional methods, such as renewable surface, good long‐term stability, excellent catalytic activity and short response time to hydrazine.

Authors: Wei Shou‐Lian , Zhao Li‐Xia , Cheng Xiang‐Lei , Lin Jin‐Ming
Published: April 2007

A flow‐injection chemiluminescence (CL) method for the determination of melatonin based on the CL reaction of melatonin with hydrogen peroxide and sodium hypochlorite (NaOCl) in a basic alkaline solution was developed. The possible CL mechanism has been discussed, and a proposal for the reaction pathway was given that singlet oxygen was clarified to be produced in this reaction system and was responsible for the CL emission. Under the optimized conditions, the linear concentration range of application was 1.0×10−7–2.5×10−4 mol·L−1 with a detection limit of 5.0×10−8 mol·L−1 (S/N=3). The relative standard deviation for eight repeated measurements of 1.0×10−6 mol·L−1 melatonin was 2.8%. The interferences of several important biological substances, some indole compound, cations and anions were studied. No interference was found for the anions, glucose, starch, most of cations and low concentration (less than 3.0×10−6 mol·L−1) of some biological substances and indole compound. The method was applied to the determination of melatonin in rat pineal gland and drug with satisfactory results. The sample throughput was 90 injections per hour.

Authors: Jia Bing‐Yu , Duan Li‐Yan , Ma Chuan‐Li , Wang Chun‐Ming
Published: April 2007

In this paper, TiO2 loaded on activated carbon fibers (ACF) was prepared by a coating treatment, followed by calcination at different temperatures in air atmosphere. The photocatalyst developed was characterized by SEM, XRD, XPS and UV‐Vis adsorption spectroscopy. It was observed from SEM images that TiO2 loaded on ACF was in the form of small clusters with nanometer size. As confirmed by XRD and XPS determinations, the crystalline pattern of immobilized TiO2 was still anatase‐form after calcination, and the micrographic structure and surface properties of ACF have not been damaged by the deposition process and calcination at different temperatures. Photocatalytic degradation of methylene blue (MB) in aqueous solution was investigated using TiO2/ACF as photocatalyst. The comparison of photolysis, absorption and photocatalysis was carried out. The results indicated that the photocatalysis process of combined photocatalyst showed much higher degradation rate than that of photolysis and absorption processes. In addition, the possibility of cyclic usage of the photocatalyst was also confirmed.
Discrete design method of transverse gradient coils for MRI
Authors: Shvartsman Shmaryu , Steckner Michael C.
Published: April 2007

A method is presented for designing transverse gradient coils for magnetic resonance imaging. This method is based on the set of Z intercepts of the coils' current patterns with the z axis in the unfolded z‐arc plane. We show that the set of Z intercepts combined with a description of the coil topology, as defined by the necessary azimuthal harmonics, the axial symmetry and the directions of the current flow, is sufficient for designing a practical gradient coil. The theory and design of transverse coils with Z intercepts is illustrated with examples of a symmetric unshielded insert gradient coil for small animal imaging, a human head unshielded symmetric insert gradient coil with shoulder cutouts, and a self‐shielded short whole‐body gradient coil. The Z‐intercept method has also been extended to design higher‐order transverse shims. This is illustrated with the design of a ZX shim. Additional design capabilities of the Z‐intercepts method are also discussed. © 2007 Wiley Periodicals, Inc.Concepts Magn Reson Part B (Magn Reson Engineering) 31B: 95–115, 2007.

Published: April 2007

Mexiletine is an antiarrhythmic drug that has a Na+channel blocking activity. The aim of the present study was to evaluate whether mexiletine had a local anesthetic effect as assessed by sciatic nerve blockade. Thus, the potency and duration of action of mexiletine on sciatic nerve blockade in terms of motor function and nociception were evaluated. Two local anesthetics, bupivacaine and lidocaine, were used as controls. Mexiletine produced a dose‐related local anesthetic effect on sciatic nerve blockade. The rank potency was bupivacaine >lidocaine >mexiletine (P<0.05 for each comparison). On an equi‐potent basis, the rank duration of action was bupivacaine>mexiletine>lidocaine (P<0.05 for each comparison). Co‐administration of mexiletine with bupivacaine produced an additive effect on sciatic nerve blockade. In conclusion, mexiletine had a local anesthetic effect on sciatic nerve blockades of motor function and nociception. Co‐administration of mexiletine with bupivacaine produced an additive effect on sciatic nerve blockade. Drug Dev. Res. 67:905–909, 2006. © 2007 Wiley‐Liss, Inc.
Performance of TCP on low‐bandwidth wireless links with delay spikes
Authors: Lassila Pasi , Kuusela Pirkko
Published: April 2007

We model the goodput of a single TCP source on a wireless link experiencing sudden increases in Round Trip Time (RTT), that is delay spikes. Such spikes trigger spurious timeouts that reduce the TCP goodput. Renewal reward theory is used to derive a straightforward expression for TCP goodput that takes into account limited sending rates (limited window size), lost packets due to congestion and the delay spike properties such as the average spike duration and distribution of the spike intervals. The basic model is for independent and identically distributed (i.i.d.) spike intervals, and correlated spike intervals are modelled by using a modulating background Markov chain. Validation by ns2 simulations shows excellent agreement for lossless scenarios and good accuracy for moderate loss scenarios (for packet loss probabilities less than 5%). Numerical studies have also been performed to assess the impact of different spike interval distributions on TCP performance. Copyright © 2007 John Wiley & Sons, Ltd.
YZβ discontinuity capturing for advection‐dominated processes with application to arterial drug delivery
Authors: Bazilevs Y. , Calo V. M. , Tezduyar T. E. , Hughes T. J. R.
Published: April 2007

The YZβ discontinuity‐capturing operator, recently introduced in (Encyclopedia of Computational Mechanics, Vol. 3, Fluids. Wiley: New York, 2004) in the context of compressible flows, is applied to a time‐dependent, scalar advection–diffusion equation with the purpose of modelling drug delivery processes in blood vessels. The formulation is recast in a residual‐based form, which reduces to the previously proposed formulation in the limit of zero diffusion and source term. The NURBS‐based isogeometric analysis method, proposed by Hughes et al. (Comput. Methods Appl. Mech. Eng. 2005; 194:4135–4195), was used for the numerical tests. Effects of various parameters in the definition of the YZβ operator are examined on a model problem and the better performer is singled out. While for low‐order B‐spline functions discontinuity capturing is necessary to improve solution quality, we find that high‐order, high‐continuity B‐spline discretizations produce sharp, nearly monotone layers without the aid of discontinuity capturing. Finally, we successfully apply the YZβ approach to the simulation of drug delivery in patient‐specific coronary arteries. Copyright © 2007 John Wiley & Sons, Ltd.
Modelling the effects of emergent vegetation on an open‐channel flow using a lattice model
Authors: Jiménez‐Hornero Francisco J. , Giráldez Juan V. , Laguna Ana M. , Bennett Sean J. , Alonso Carlos V.
Published: April 2007

A two‐dimensional lattice model has been developed to describe the influence of vegetation on the turbulent flow structure in an open channel. The model includes the influence of vegetation density on the frictional effect of the channel bed and walls. For the walls, a semi‐slip boundary condition has been considered as an
alternative to overcome the no‐slip boundary condition limitations in turbulent flows. The drag stress exerted by the flow on the vegetation as well as the gravity effect has also been taken into account. The proposed lattice model has been used to simulate the experimental results reported from the study of the influence of alternate vegetated zones on the open‐channel flow. The results show that the lattice model approach is a valid tool for describing these kinds of flows. Copyright © 2007 John Wiley & Sons, Ltd.
Adaptive VOF with curvature‐based refinement
Authors: Malik Mayank , Fan Eric Sheung‐Chi , Bussmann Markus
Published: April 2007

Adaptive refinement is implemented in the context of the volume‐of‐fluid (VOF) methodology in order to study the efficacy of resolving interfaces adaptively based on the local value of curvature. The usual uniform mesh VOF implementation is modified slightly to ensure accurate advection of fluxes between cells at different resolutions. Normals and curvatures are calculated accurately via height functions. Results of a series of tests indicate that in most instances the use of adaptive refinement (when compared to uniform refinement with a similar number of cells) leads to more accurate VOF advection. The results also clearly show that curvature‐based adaptive refinement leads to a distribution of errors along an interface that is nearly independent of curvature.

Genetic influences on human brain structure: A review of brain imaging studies in twins
Authors: Peper Jiska S. , Brouwer Rachel M. , Boomsma Dorret I. , Kahn René S. , Hulshoff Pol Hilleke E.
Published: April 2007

Twin studies suggest that variation in human brain volume is genetically influenced. The genes involved in human brain volume variation are still largely unknown, but several candidate genes have been suggested. An overview of structural Magnetic Resonance (brain) Imaging studies in twins is presented, which focuses on the influence of genetic factors on variation in healthy human brain volume. Twin studies have shown that genetic effects varied regionally within the brain, with high heritabilities of frontal lobe volumes (90–95%), moderate estimates in the hippocampus (40–69%), and environmental factors influencing several medial brain areas. High heritability estimates of brain structures were revealed for regional amounts of gray matter (density) in medial frontal cortex, Heschl's gyrus, and postcentral gyrus. In addition, moderate to high heritabilities for densities of Broca's area, anterior cingulate, hippocampus, amygdala, gray matter of the parahippocampal gyrus, and white matter of the superior occipitofrontal fasciculus were reported. The high heritability for (global) brain volumes, including the intracranium, total brain, cerebral gray, and white matter, seems to be present throughout life. Estimates of genetic and environmental influences on age‐related changes in brain structure in children and adults await further longitudinal twin‐studies. For prefrontal cortex volume, white matter, and hippocampus volumes, a number of candidate genes have been identified, whereas for other brain areas, only a few or even a single candidate gene has been found so far. New techniques such as genome‐wide scans may become helpful in the search for genes that are involved in the regulation of human brain volume throughout life.

B7‐H1, a coinhibitory molecule, plays a role in immune escape of tumors. We have shown previously the expression of this molecule in breast cancer patients and demonstrated its association with high histological grade, progesterone and estrogen receptor negative status, all of which are known to have direct impact on cell proliferation. In the present work, we investigated the effect of proliferation, as measured by Ki‐67 and mitotic count, on the induction of B7‐H1. We used H&E stained sections to score for mitotic count in 69 breast cancer patients. Immunohistochemistry was used to investigate B7‐H1 and Ki‐67 expression. The relationship between B7‐H1 induction and cell proliferation was further investigated in primary cultured cells. B7‐H1 expression was recorded in patients with a high mitotic index (p = 0.007). There was a high significant correlation between B7‐H1 expression and the presence of the proliferative marker Ki‐67 (p < 0.001) indicating the association of proliferation with B7‐H1 induction. Furthermore, B7‐H1 was gradually induced in proliferating cells of 8/8 primary cell lines as measured by Ki‐67 expression. Finally, B7‐H1 was downregulated in quiescent cells and upregulated in cells stimulated with a mitogen confirming the association of proliferation with the induction of B7‐H1. We have shown for the first time a direct association between proliferation and the expression of B7‐H1 in breast cancer patients. The relationship between B7‐H1 induction and cell proliferation was also thoroughly investigated in vitro, in which a strong link between B7‐H1 expression and the presence of the proliferative Ki‐67 marker was clearly demonstrated. © 2007 Wiley‐Liss, Inc.
