Abstract We present an archive of scanned instrumental seismic bulletins pertaining to either a single station or a set of stations (network). This new service by the International Seismological Centre (ISC), called the ISC Electronic Archive of Station and Network Bulletins, is openly available at the ISC website. The archive is likely to be the most comprehensive to date, thanks to the collection from various sources done by the ISC in the past several decades. The search for scans of a seismic bulletin is based on the location of the town of the institution producing a bulletin. As such, the electronic archive is easy to use and is likely to facilitate the work of a wide community interested in studying past earthquakes and involved in preservation and digitization of analog recordings.

Medical Analysis

Medical analysis laboratory must establish its own reference intervals depending on the facilities they are working with, the working substances and protocols. These reference intervals must be obtained depending on age groups in order to accurately interpret the results of the analyzes performed. The study is a retrospective one using 3217 data from the electronic archive of the S.C. Vladutiu&Garabedian S.R.L. Clinic in Medias. Total serum calcium was determined by the colorimetric method on the Konelab analyzer. Processing of the collected data was done using the Hoffmann method, considering 5% up to 95% of the values in the database, the values being randomly selected. For comparison, data from the literature was used. In children under 1 year old, it was not possible to calculate the reference intervals since data was insufficient. In the other age groups, reference intervals obtained in the current study were similar to the studied literature. Reference intervals established for calcium can provide important guidance for the reasonable supplementation of this essential element in children.

The article discusses some aspects of the organization of the information system of the Archive of the First President of the Republic of Uzbekistan Islam Karimov. The problem of digitalization of archival activities is quite relevant for Uzbekistan due to the fact that traditional approaches to the construction of information retrieval mechanisms and the organization of information services in archiving today often do not correspond to the required level of efficiency and user needs. As part of the work carried out, the specific task was to organize a software environment for the formation of an electronic catalog of archived descriptions, filling databases of digitized copies of archival materials, as well as flexible multidimensional search and presentation of information. The way to solve this problem is to use the archival information system «AtoM». As a result, a database of digitized archival materials was created, reflecting the life and work of the First President of the Republic of Uzbekistan Islam Karimov, equipped with a developed search and reference apparatus.

Abstract Moderate to large earthquakes within an earthquake catalogue contribute significantly to the seismic hazard and risk assessment results of any region. Thus it is prudent to ensure these events have reliable source parameters (epicentres and magnitude). The dataset of events compiled in this study contains a total of 117 instrumentally recorded events of magnitude M ≥5.0, whose parameters were obtained from the Council for Geoscience (CGS) and International Seismological Centre (ISC) databases. The events are mostly located in South Africa with a few in neighbouring countries. Parametric data made up of all available phase data and amplitudes associated with each of the earthquakes were compiled. The availability of these data enabled the earthquake epicentres and magnitude values to be recalculated using the velocity model and the local magnitude relation that are currently being used by the CGS in its analysis of national seismic data. The accuracy of the relocations was determined by producing and analysing three parameters, the azimuthal distribution of seismograph stations (GAP), root-mean-square of travel time residuals (RMS) and epicenter location error data. The analysis of these parameters showed that there was an improvement in the accuracy of the relocated events. Using the ISC location algorithm, iLOC, eight preselected events were further analysed. From this analysis, two earthquakes were found to satisfy the conditions for Ground Truth (GT595%) candidacy whilst four events satisfied the criteria for GT2090% candidacy.
