A computer program "PARAV" for calculating various optical constants, e.g., the dispersion of refractive index, optical absorption coefficient, optical thickness and optical bandgap, from experimentally measured transmission spectra of bulk materials and thin films is developed. User-friendly interface, convenient input and output of the measured and calculated data in the form of text files are also a feature of this software. Data from amorphous semiconductors (chalcogenide glasses and thin films and a-Si:H) are used as typical examples to check the reliability of the program.

This work describes a computer program for the design of four types of 4 He cooled cryostats. Contributions to the thermal balance are computed and the positions of the 4 He gas cooled shields are determined by optimizing the time for which the helium stays in the main bath. The four types of cryostat considered are also described, along with some examples to illustrate how to make good use of this program.

Background: The photobleaching fluorescence resonance energy transfer (pbFRET) technique is a spectroscopic method to measure proximity relations between fluorescently labeled macromolecules using digital imaging microscopy. To calculate the energy transfer values one has to determine the bleaching time constants in pixel-by-pixel fashion from the image series recorded on the donor-only and donor and acceptor double-labeled samples. Because of the large number of pixels and the time-consuming calculations, this procedure should be assisted by powerful image data processing software. There is no commercially available software that is able to fulfill these requirements. Methods: New evaluation software was developed to analyze pbFRET data for Windows platform in National Instrument LabVIEW 6.1. This development environment contains a mathematical virtual instrument package, in which the Levenberg-Marquardt routine is also included. As a reference experiment, FRET efficiency between the two chains (beta 2-microglobulin and heavy chain) of major histocompatibility complex (MHC) class I glycoproteins and FRET between MHC I and MHC 11 molecules were determined in the plasma membrane of JY, human B lymphoma cells. Results: The bleaching time constants calculated on pixel-by-pixel basis can be displayed as a color-coded map or as a histogram from raw image format, Conclusion: In this report we introduce a new version of pbFRET analysis and data processing software that is able to generate a full analysis pattern of donor photobleaching image series under various conditions.

A computer program (CHMASS) is described that calculates characteristic mass (m(o)) values for electrothermal atomic absorption spectrometry (ETAAS) following user-specified input of atomizer type or dimensions and atomization temperature. All the necessary spectroscopic and physical parameters for calculating m(o) values for 40 elements (and 44 analytical wavelengths) commonly determined by ETAAS are included in the database. Application of the program is illustrated by several theoretical and practical examples: (i) a study of the effect of atomization temperature on absorption and diffusion coefficients for silver;(ii) an investigation of how the sample injection hole limits the maximum attainable ETAAS sensitivity for copper as the tube length is increased;(iii) optimization of the atomization temperature for the determination of cadmium in a standard reference material;and (iv) a comparison of several commercial atomizer designs as regards the calculated atomization efficiencies using data from the manufacturers' literature. This last comparison provides further evidence for the superiority of platform atomization and integrated absorbance measurements over wall atomization combined with peak height evaluation.

A microcomputer program is described for planning and statistically evaluating microplate and other similar experiments. This program is written in BASIC and can bc run on any PC XT/AT compatible computer under DOS. The first part of the program writes the protocol of the experiment into a disk file and sends it to a printer and also prints specifications for the addition ot' ingredients. The second part of the program calculates means and standard deviations of the values measured for all groups of samples. It is also possible for the program to calculate activation coefficients, coefficients of modulation and percentages of suppression for special groups. Inputting the required data can be performed manually from the keyboard or automatically from disk files.

A new computer program is reported that provides work schedules for nursing staff. Designed to run on the NEC PC-9801 personal computer using the N88-BASIC(86) interpreter, this program is intended for use by the senior nurses of each ward and removes most of the manual burden of staff work scheduling. The word work schedule can be created in only 90 seconds by the program and allows for individual nursing staff requests for particular work assignments.

The computer program for the calculation of particle trajectories of a beam with high density of space charge, in complicated static electric and magnetic fields with rotational symmetry is described. Careful selection of numerical methods and comparatively general arrangement make the program applicable to a wide field of problems. As an example, the accel-decel extraction system of an ion source is solved.

The application of a computer program for the conductimetric-potentiometric determination of acid concentrations in a mixture characterized by small differences in the dissociation constants of the components is described. The conductimetric method is based on the technique of graphical direction lines, thus providing data on the concentrations of H3O+ ions and the undissociated portion of [HA]. Together with acid dissociation constants, these data were used for calculating the concentrations of individual components of the mixture, dissociation of acid degree, pH and dissociation constant. The same solution was analysed separately by the conductimetric and potentiometric methods for comparison.

Introduction: A depressed patient presents cognitive impairment that remains in spite of depression's remission. This study intends to evaluate the impact of cognitive training in the treatment of depression, and also of the impairment that depression causes. Method: A program for cognitive training (Alcor) was designed for and applied to a group of patients (n = 10) with non-medicated MDD;a group (N = 10) with MDD that was treated with the program and with anti-depressants, and to another group (n = 11) that was given anti-depressors only. The impact of this intervention was assessed by applying the following instruments: Beck Depression Inventory, WAIS, Spielberger State-Trait Anxiety Inventory, Externalized Problems Assessment Scale for Adolescents and Young Adults, and Attention Problems Assessment Scale. The program was applied to University students with MDD twice a week, until they had reached adequate levels of execution. Results: The patients of all three groups showed MDD event remission. Those who received cognitive training showed a substantial increase of intellectual performance. The cognitive treatment group increased IQ in 12.9 units and the combined group increase in 13.3 units. There was a slight decrease of 1.9 units within the anti-depressant treatment group. The changes in attention and in externalized problems showed the same trends. (C) 2007 Elsevier Ltd. All rights reserved.
