Published: August 2002

AbstractA low molecular weight fucan fraction extracted from the brown seaweed Ascophyllum nodosum was previously shown to exhibit dose‐related venous antithrombotic activity with an ED80 of about 20 mg/kg, 2 h after a single subcutaneous injection HCII (Colliec et al. [1991] Thromb Res 64:143–154; Mauray et al. [1995] Thromb Haemast 74:1280–1285). Its activity was comparable to that of a low molecular weight heparin (Dalteparin®). This fucan fraction is one of several, with a range of different structure parameters, prepared by degradation of the whole native fucan. These low molecular weight fractions were compared using a Wessler stasis thrombosis model in rabbits and by determination of their in vitro and ex vivo anticoagulant activities. Intravenous administrations of these fractions reduced thrombosis in a dose‐dependent manner. Partial removal of sulfate groups and/or partial degradation lead to a significant decrease in their anticoagulant and antithrombotic activities. The integrity of the regular pattern of sulphation of the fucoidan is necessary for antithrombotic activity. Drug Dev. Res. 51:216–224, 2000. © 2001 Wiley‐Liss, Inc.
Age differences in arousal and vigilance in California ground squirrels (Spermophilus beecheyi)
Authors: Hanson Mark T. , Coss Richard G. 
Published: August 2002

AbstractNewly emerged pup, juvenile, and adult California ground squirrels (Spermophilus beecheyi douglasii) were videorecorded at a seminatural field site in northern California. Video data revealed age differences in the budgeting of ground squirrel behavior, habitat use, and physiological arousal as indicated by morphometric analyses of tail piloerection. Adults and juveniles devoted their time to foraging in the open at feeding stations while displaying low to moderate levels of arousal, respectively. Pups remained vigilant on the fringe of covered habitats while displaying comparatively higher levels of arousal. Higher pup arousal may facilitate memory formation during early stages of development. © 2001 John Wiley & Sons, Inc. Dev Psychobiol 39: 199–206, 2001
Isolation and expression analysis of three zebrafish angiopoietin genes
Authors: Pham Van N. , Roman Beth L. , Weinstein Brant M. 
Published: August 2002

AbstractThe Tie1 and Tie2 receptor tyrosine kinases and the Tie2 ligands, the angiopoietins, play critical roles in vertebrate vascular embryogenesis, helping to mediate the interaction between endothelial cells and the pericytes or vascular smooth muscle cells that envelop and support them. We have obtained full‐length cDNA sequences for zebrafish orthologs of angiopoietin‐1 (ang1), angiopoietin‐2 (ang2), and angiopoietin‐like‐3 (angptl3). Ang1 is expressed in head ventral mesenchyme, in the ventromedial region of somites, in mesenchyme surrounding trunk axial vessels, and in the hypochord, a transient embryonic structure of endodermal origin that has been implicated in dorsal aorta assembly in both zebrafish and Xenopus. Ang2 is expressed in head and anterior trunk ventral mesenchyme and the developing pronephric glomeruli. Angptl3 is expressed in the yolk syncytial layer. © 2001 Wiley‐Liss, Inc.
Localization of Lutheran, a novel laminin receptor, in normal, knockout, and transgenic mice suggests an interaction with laminin α5 in vivo
Authors: Moulson Casey L. , Li Cong , Miner Jeffrey H. 
Published: August 2002

AbstractLaminins are major components of all basement membranes. One laminin that has garnered particular interest, due to its widespread expression pattern and importance during development, is the laminin α5 chain. In vitro studies have suggested that the Lutheran blood group glycoprotein/basal cell adhesion molecule (Lu), an Ig superfamily transmembrane protein, is a receptor for laminins containing the α5 chain. However, there are no in vivo studies showing that these proteins are capable of interacting in tissues. We have isolated the mouse ortholog of Lu and characterized its expression and localization in mouse tissues. Lu was primarily found on the basal surface of epithelial cells and on muscle cells adjacent to basement membranes containing laminin α5. In addition, there was both a dramatic reduction in the basal concentration of Lu in mice lacking laminin α5, and a significant increase in Lu protein in transgenic mice overexpressing laminin α5. Together, these data provide the first in vivo evidence for an interaction between Lu and laminin α5 and support the hypothesis that Lu is a laminin α5 receptor. We propose that laminin α5 is involved in concentrating Lu on the basal surface of epithelial cells. This may be one mechanism by which basement membrane signals are transmitted to the cell. © 2001 Wiley‐Liss, Inc.
Coarseness error and wall process near conductor corner in the FDTD method
Authors: Iida Yukio 
Published: August 2002

AbstractThis paper investigates the errors in the FDTD method due to the mesh coarseness from the point of view of mesh arrangement. A cavity with an inductive window is chosen as an object for analysis. When the aperture width is small and the external Q is large, the numerical accuracy of the electromagnetic field near the conductor corner in the inductive window is strongly reflected in the external Q. This fact is used for the investigation. A new mesh arrangement applicable to the conductor corner is proposed. © 2002 Scripta Technica, Electron Comm Jpn Pt 2, 85(3): 9–15, 2002
Coupling Characteristics of Microstrip Lines through an Elliptical Slot
Authors: Kobayashi Hiromi , Wakabayashi Toshio 
Published: August 2002

AbstractMonolithic microwave integrated circuits are useful for miniaturization, weight reduction, and performance enhancement of components at microwave and millimeter‐wave frequencies. In this paper, a simple method is proposed for analysis of the coupling characteristics of laminated microstrip lines through an elliptical slot in the common ground plane. The results of the analysis by this method are presented and are compared with experimental values, demonstrating the effectiveness of the method. In this method, an elliptical slot is subdivided into infinitesimal rectangular slots. The characteristics of individual infinitesimally small rectangular slots are synthesized by means of the theory of multihole directional couplers to allow analysis of the coupling characteristics by an elliptical slot. The characteristics by individual slots are derived by means of the conventional theory. In this paper, the derivation is made more rigorous. © 2001 Scripta Technica, Electron Comm Jpn Pt 2, 85(1): 13–21, 2002
Reducing the Numerical Dispersion in the FDTD Analysis by Modifying Anisotropically the Speed of Light
Authors: Suzuki Kosuke , Kashiwa Tatsuya , Hosoya Yoshio 
Published: August 2002

AbstractIn FDTD analysis, one of the problems is numerical dispersion caused by the discretization of time and space. In a previous publication, the present authors generalized a speed‐of‐light correction method previously applied only to isotropic meshes so that it could be applied to an anisotropic mesh. However, in the previously reported correction method the speed of light was corrected isotropically. Therefore, the error compression was small in the aniso‐tropic mesh. In this paper, a correction method is proposed in which more compression of the phase error than in the previous method is possible in an anisotropic lattice. By applying the new method to a two‐dimensional nonuniform mesh, the effectiveness of the method is demonstrated. © 2001 Scripta Technica, Electron Comm Jpn Pt 2, 85(1): 50–58, 2002
Development of a 3D display system for surgical navigation
Authors: Nakajima Susumu , Masamune Ken , Sakuma Ichiro , Dohi Takeyoshi 
Published: August 2002

AbstractFor image‐guided surgery using 3D medical images, we have developed a 3D display system employing the principle of integral photography (IP). This system consists only of an AT‐compatible computer, a liquid‐crystal display (LCD), and a lens array. The image for display is constructed by an algorithm for high‐speed rendering based on the principle of IP.The 3D image is projected and displayed in space and can be seen by multiple observers in accordance with the observing position without using special glasses or position sensors. Moreover, since the projected 3D image can be moved by manipulation by the observer, the preoperative information operation can be grasped intuitively during the operation by aligning the preoperative 3D image with the observing direction of the patient. The 2D resolution and depth‐direction resolution of the projected image based on this system are both in proportion to the resolution of the LCD that is used, which at the present stage is insufficient. However, in this system, since it is in principle possible to display a 3D image accurately with a simple device and to change the direction of observation, this system may be usable in image‐navigated surgery when higher‐precision LCDs become available in the future. © 2001 Scripta Technica, Electron Comm Jpn Pt 3, 84(10): 15–24, 2001
Resonance of elliptical muffler chamber having a nonuniformly perforated pipe
Authors: Nishimura Tsuyoshi , Ando Tadashi , Ikeda Tatsuyu 
Published: August 2002

AbstractPerforated pipe is an essential component in contemporary automotive mufflers, since such a pipe reduces the acoustic power of the flow noise, which is significantly influenced by its velocity. Nonuniformly perforated pipes, the orifices of which are arranged in a belt configuration, are widely used in muffler systems. The resonance of such perforated pipe when located inside the elliptic cavity is investigated experimentally in this paper. The results obtained are also compared with the predictions of our method of theoretical analysis for a uniformly perforated pipe in order to clarify the resonance mechanism. It was found that the difference between the measured and theoretical values is less than 5 Hz for a short pipe. © 2002 Wiley Periodicals, Inc.

Measurement of negative ion mobilities at atmospheric pressure in O2/O3 mixtures
Authors: Hayashi Takahisa , Itoh Haruo 
Published: August 2002

AbstractIn a previous work, we measured the negative ion mobilities in O2 at atmospheric pressure. The obtained zero‐field mobility of $\hbox{O}^{-}_{2}$ in O2 agreed well with the results of Snuggs and co‐workers. However, we mentioned that the apparent zero‐field mobility tended to small values with increase of the drift length. This paper describes experimental results for the negative ion mobilities in O2/O3 mixtures. Ozone was generated in a silent discharge tube and the ozone concentration was varied from 10 ppm up to 1200 ppm. It was found that the negative ion mobilities become smaller with increases of the ozone concentration. When ozone was mixed above 10 ppm in O2, the mobility decreased rapidly. The apparent zero‐field mobility was 1.69 cm2/V·s at 300 ppm O3 and 1.52 cm2V·s at 1200 ppm O3. Within this range from 300 to 1200 ppm O3, the apparent zero‐field mobility decreased linearly with increases of the ozone concentration. This suggests that cluster ions are formed by some ion‐molecule reactions in the drift space. © 2001 Scripta Technica, Electr Eng Jpn, 138(3): 26–33, 2002
Suggestion and feasibility study for a massively parallel back‐to‐back system
Authors: Sato Tadashi , Matsushita Yoshinao , Temma Koji , Iyoda Isao 
Published: August 2002

AbstractThis paper presents a new concept for back‐to‐back (BTB) dc systems. The main feature of the proposed BTB is referred to as “massively parallel.” This massively parallel BTB system consists of a number of small or mediumcapacity inverter units that are connected in parallel. The concept of transmission power control using the massively parallel BTB is investigated using MATLAB for a case where a fault occurs. In addition, a method for modeling the proposed BTB in EMTP is investigated. The work presented in this paper shows that the proposed BTB system is very promising for large power system applications because the losses of the system are very small compared to conventional BTB using VSC (voltage source converter). The massively parallel BTB can keep operating even if an inverter unit fails, thus improving overall power transmission capability. © 2001 Scripta Technica, Electr Eng Jpn, 138(3): 34–42, 2002
On the measurement of social orientations in the minimal group paradigm: norms as moderators of the expression of intergroup bias
Authors: Gaertner Lowell , Insko Chester A. 
Published: August 2002

AbstractContrary to most other research conducted in the minimal group paradigm tradition, Bornstein, Crum, Wittenbraker, Harring, Insko and Thibaut (1983a) found little evidence of ingroup favoritism when they employed a revised measurement system (i.e. the Multiple Alternative Matrices; MAMs). The current experiment examined whether Bornstein et al.'s effects could be attributed to norms that prohibit intergroup discrimination, which are made salient by framing the outcome values in the intergroup allocation task as monetary payment. We manipulated the salience of prohibitive norms by varying whether participants allocated on the MAMs monetary payment, bonus money or feelings. Participants more strongly associated ‘having to be fair and equal’ with payment than with bonus or feelings and category members made fewer allocations that maximized the ingroup's relative and absolute profit and more allocations that minimized intergroup differences when allocating monetary payment than when allocating bonus money or feelings.

Comparison of theoretical derivations, simple linear regressions, multiple linear regression and principal components for analysis of fish mortality, growth and environmental temperature data
Authors: Jensen A. L. 
Published: August 2002

AbstractNatural mortality of fish populations is difficult to estimate, and parameters for growth and environmental temperature, which are easier to estimate, have been applied to predict fish natural mortality using multiple linear regression. There are theoretical relations among all of the variables applied in the multiple linear regression, and there is high multicollinearity; the results of the multiple regression differ considerably from the theoretical relations among the variables. Simple linear regression results agree with the theoretical results but they are not as precise for prediction of mortality as multiple linear regression. A principal components analysis correctly identifies the important variables and the relations among variables but it is more complex than multiple linear regression and yet is not any more precise for predictions. A plot of the first two principal components separated the data into two groups: one was temperate water species and one was warmer water species. The analysis confirms the limitations and advantages of different data analysis methods. Copyright © 2001 John Wiley & Sons, Ltd.
A nonlinear numerical model for sloped‐bottom tuned liquid dampers
Authors: Olson D. E. , Reed D. A. 
Published: August 2002

AbstractShaking‐table data for a tuned liquid damper with a sloped bottom of 30° with the horizontal are investigated using a non‐linear numerical model previously developed by Yu, Jin‐kyu, Nonlinear characteristics of tuned liquid dampers. Ph.D. Thesis, Department of Civil Engineering, University of Washington, Seattle, WA, 98195 (1997). Stiffness and damping parameters for this model are obtained and compared with those previously derived for box‐shaped tanks. The values for these parameters reflect the softening spring behaviour of the sloped‐bottom system in contrast to the hardening system evident for the box‐shaped TLD. Consequently, the sloped‐bottom tank should be tuned slightly higher than the fundamental structural frequency in order to obtain the most effective damping. Copyright © 2001 John Wiley & Sons, Ltd.

Authors: Clowers Brian H. , Steiner Wes E. , Dion Heather M. , Matz Laura M. , Tam Maggie , Tarver Edward E. , Hill Herbert H. 
Published: August 2002

AbstractThe purpose of the current study was to explore and assess the potential of high resolution electrospray ionization atmospheric pressure ion mobility spectrometry (ESI–AP‐IMS) as a field analytical method for the detection and identification of mixtures of sulfonylurea (SU) herbicides in aqueous samples. Because of increased usage, persistent behavior, and potential for crop damage, an environmental method of analysis capable of evaluating SU herbicides in a swift and effective manner is necessary. Eight SU herbicides were evaluated using ESI–AP‐IMS quadrupole mass spectrometry. The selected herbicides were chosen based upon availability and scope of use. The SU herbicide species were qualitatively identified using quadrupole mass spectrometry, followed by the determination of reduced mobility values for characteristic ions. Various mixtures of rimsulfuron, metsulfuron‐methyl, prosulfuron, sulfometuron‐methyl, tribenuron‐methyl, and primisulfuron‐methyl could be revealed using AP‐IMS. The ease of use, ability to operate under ambient conditions, and relatively rapid data acquisition times make ESI–AP‐IMS an attractive candidate for the analysis of aqueous environmental field samples. © 2002 Wiley Periodicals, Inc.

AbstractThree essential oils obtained by hydrodistillation from the leaves, roots and stem barks of Croton zambesicus Muell. Arg. (Euphorbiaceae) were analysed by GC and GC–MS. This West Tropical African species has many uses, especially as a drug source for the cure of many ailments. The three organs were found to contain 0.17–0.34% yield of oil. The qualitative composition of the three types of oil were found to be similar; those from the leaves and stem bark were found to be rich in monoterpenes (69.6% and 75.2% respectively), while the root bark oil contained 57.0% sesquiterpenes. The root and stem barks oils were found to be rich in oxygen‐containing compounds, with spathulenol (14.0%) and linalool (33.8%) as the major components, respectively. The leaf oil was found to contain mainly hydrocarbons and only 11.6% of oxygenated compounds. Copyright © 2002 John Wiley & Sons, Ltd.
Finite element study of free surface turbulent flow in rotating channels
Authors: Pagalthivarthi Krishnan V. , Ramanathan Veeraraghavan 
Published: August 2002

AbstractUnder certain conditions of liquid flow through rotating channels, the Coriolis force can induce a free surface to be formed. This problem is of practical importance in a Coriolis wear tester, which is used for determining the sliding wear coefficient of wear materials in slurry handling equipment. A deforming Galerkin finite element method is presented for predicting two‐dimensional turbulent free surface mean flow in rotating channels. Reynolds‐averaged Navier–Stokes (RANS) equations are cast into weak(algebraic) form using primitive variables (velocity and pressure). Eddy viscosity is determined via a mixing length model. Velocity is interpolated biquadratically, while pressure is interpolated bilinearly. The kinematic condition is used to form the Galerkin residual for the free surface. The free surface is represented by Hermite polynomials of zeroeth order for continuity of position and slope. Combined Newton's iteration is used to simultaneously solve for the free surface and the field variables. Results of velocity and pressure fields, as well as the free surface are shown to converge with mesh‐size refinement. There is excellent respect for mass conservation. Results are presented for various values of Rossby number (Ro) and height‐based Reynolds number (ReH). Parameter continuation in Ro and ReH space is used to compute solutions at higher values of flow rate and angular velocity. Copyright © 2002 John Wiley & Sons, Ltd.
