A numerical approach to the voltammograms of the reduction of Prussian Blue films on ITO electrodes
1997
The uncompensated resistance, mainly due to the ITO electrode, modifies the shape of voltammetric curves of the system Prussian Blue ⇄ Everitt's Salt films deposited on this transparent electrode. A numerical finite difference model which is able to explain the shape of these voltammetric curves is studied in this paper. This model explains the dependence of voltammetric curves on the film thickness and uncompensated resistance.
Detection of primary DNA damage in Chlamydomonas reinhardtii by means of modified microgel electrophoresis.
1997
The assessment of genotoxic potential in surface water requires test methods, among which are those that detect initial DNA damage in organisms of aquatic biocenosis. The microgel electrophoresis (MGE) "comet assay" was applied to a ubiquitous unicellular green alga (Chlamydomonas reinhardtii) to detect DNA damage caused by genotoxins. For this, the test protocol described by Singh NP et al. [Exp Cell Res 175: 184-191, 1988] was modified. Major modifications were the use of alkaline lysis buffer with ionic detergents and the reduction of preincubation and electrophoresis times. Short-time exposure of Chlamydomonas to the well-known genotoxicants 4-nitroquinoline-1-oxide (4-NQO), N-nitrosodi…

Metamorfosi di una Novella in Tragedia nell’opera di G. B. Giraldi Cinzio
1997
Mediante el análisis pormenorizado contrastivo de la obra de teatro de Selene, así como de la Novella de Selene de las “Ecatommiti” (Novella I, V Deca) de Giraldi, Romera Pintor establece las semejanzas y diferencias, demostrando al mismo tiempo que Giraldi escribió, si no todas, al menos muchas de sus Novelle con posterioridad a la redacción de aquellas de sus tragedias que presentan la misma temática.
Dynamic error-components models with autocorrelated disturbances : a brief survey
1997
Studying dynamic error component models with autocorrelated disturbances has started very recently in econometrics analysis of panel data. There is no article or book which tackles this topic exhaustively. In this study, a brief survey of these models is presented. The within, between, OLS, GLS, maximum likelihood and instrumental variable estimators are especially analysed, and the particular characteristics of these models are underlined each time.

Angiosarcoma del muslo: diagnóstico diferencial
1997
Se presenta un caso de angiosarcoma de partes blandas en un paciente de 92 años localizado en extremidad inferior de seis meses de evolución. Estos tipos de tumores muestran probabilidades de ser confundidos con hematomas, incluso con estudios de Resonancia Nuclear. Se destaca la ayuda que ofrece para el diagnóstico la arteriografía, así como la agresividad de dichos tumores y los posibles abordajes terapéuticos actuales. A case of angiosarcoma is presented. The patient was 92 years old. The tumor was present 6 months before diagnosis. The tumor was diagnosed by MRN as haematoma of the muscle. Arteriography is a good diagnostic tool before the biopsy in that type of lesions. Alternative tre…

The TH1 Lymphokine Interferon-γ is a Potent Upregulator of Dendritic Cells with Phagocytic Capacity in GM-CSF Supplemented Bone Marrow Cultures
1997
Myeloid dendritic cells (DC), macrophages and granulocytes are descendants of a hematopoietic progenitor cell that originates in the bone marrow1. Thus, bone marrow derived cells distributed in tissue culture in the presence of GM-CSF give rise to the three leukocyte populations which under various in vitro culture conditions proceed in differentiation and phenotypic maturation2–7.
A Survey of Continuous-Time Computation Theory
1997
Motivated partly by the resurgence of neural computation research, and partly by advances in device technology, there has been a recent increase of interest in analog, continuous-time computation. However, while special-case algorithms and devices are being developed, relatively little work exists on the general theory of continuous- time models of computation. In this paper, we survey the existing models and results in this area, and point to some of the open research questions. Final Draft peerReviewed
The STR252-IVS10nt546-VNTR7 phenylalanine hydroxylase minihaplotype in five Mediterranean samples.
1997
IVS10nt546 (IVS10nt-11g→a) is the most common molecular defect of the phenylalanine hydroxylase gene causing phenylketonuria in Mediterranean populations. Previous studies have proposed various and alternative hypotheses concerning the geographical origin and pattern of diffusion of this mutation in this area. In this study, this issue was re-examined on a large sample (149) of “Mediterranean” IVS10nt546 mutant alleles analysed with multiallelic intragenic polymorphisms. The analysis of intragenic microsatellite (STR) and minisatellite (VNTR) polymorphisms shows allelic heterogeneity of the IVS10nt546 mutation. Eight STR and three VNTR alleles were found in association with the splicing def…

Oxidative DNA Damage Profiles in Mammalian Cells
1997
Reactive oxygen species (ROS) are formed inside cells not only under the influence of exogenous agents (visible light, ionizing radiation, and many oxidants such as peroxides or quinones), but also under normal (physiological) conditions as byproducts of oxygen metabolism and other cellular redox reactions (Pryor 1986; Halliwell and Gutteridge 1986; Sies 1986; Clayson et al. 1994). ROS such as hydroxyl radicals and singlet oxygen are a serious threat to the integrity of the cellular genome, since they efficiently react with DNA to generate many types of DNA modifications, at least some of which are pre- mutagenic (Breimer 1990; Halliwell and Aruoma 1991; Epe 1991; Feig et al. 1994). Steady-…
Parallel Genetic Solution for Multiobjective MDO
1997
Publisher Summary This chapter reviews a multiobjective, multidisciplinary design optimization of two-dimensional airfoil designs. The control points on leading and trailing edges remain fixed, and the y-coordinates of the other control points are allowed to change during the optimization process. The grid for the Euler solver depends continuously and smoothly on the design parameters. The number of nodes and elements in the mesh might vary according to design because the meshes for the Helmholtz solver are done using the local fitting. The computations are made on an IBM SP2 parallel computer using high-performance switch and the MPICH message-passing library. As gradients are not required…
Optimizing self-organizing timbre maps: Two approaches
1997
The effect of using different auditory images and distance metrics on the final configuration of a self-organized timbre map is examined by comparing distance matrices obtained from simulations with a similarity rating matrix, obtained using the same set of stimuli as in the simulations. Two approaches are described. In the static approach, each stimulus is represented as a single multi-component vector. Gradient images, which are intended to represent idealizations of physiological gradient maps in the auditory pathway, are constructed. The optimal auditory image and distance metric, with respect to the similarity rating data, are searched using the gradient method. In the dynamic approach…
Minimally invasive plate fixation in femoral shaft fractures
1997
Bridge-plating with its advantages in terms of vascularity and bone healing is a well established procedure today in the treatment of comminuted femoral fractures. Bridge-plating means that the fracture site is not interfered with during the operative procedure. This paper introduces a surgical technique in which the plate is inserted through isolated proximal and distal incisions only, behind the vastus lateralis. Alignment is secured by the plates, the fracture site remains untouched, fixation and screw insertion is restricted to the proximal and distal main fragments. Longitudinal femoral fractures extending right into the trochanteric and or condylar areas are the main indication for mi…
Chirped fibre Bragg gratings for phased-array antennas
1997
A variable delay line for phased-array antennas based on a chirped fibre Bragg grating is demonstrated. The time delay of a microwave modulating signal is modified by scanning in wavelength a chirped grating. In this initial experiment, time delay variations up to 556 ps have been achieved using a grating of 0.4 nm bandwidth and 6 cm length and modulating in the frequency range 390 MHz-5.20 GHz.
