    MCE mixtures fortified with fine rubber were the subject of research in laboratory tests in Lublin University of Technology. As a basic literature review shows, an amount of fine rubber in mixtures with cement in MCEM should be 2%, 4% and 6% of the aggregate. The mixtures were designed planned and prepared as samples for tests assessing the fulfillment of the requirements contained in the Manual [9]. Analysis of the results allows to assess the usefulness of fine rubber in MCE mixtures and is a basis for further detailed studies that are aimed at setting new quantitative requirements, going beyond the requirements included in the Manual.Mieszanki MMCE z dodatkiem miału gumowego były przedmiotem rozpoznawczych badań laboratoryjnych przeprowadzonych w Politechnice Lubelskiej. Ustalono wstępnie na podstawie przeglądu literatury, dotyczącej stosowania miału gumowego do mieszanek związanych cementem, jego dodatek w ilości 2%, 4% i 6% w stosunku do kruszywa. Zaprojektowano mieszanki a następnie wykonano próbki i przebadano je pod kątem spełnienia wymagań w zawartych w Instrukcji [9]. Analiza uzyskanych wyników pozwala stwierdzić przydatność miału gumowego w mieszankach MCE i stanowi postawę do opracowana dalszych szczegółowych prac w celu ustalenia nowych wymagań ilościowych wykraczających poza wymagania zawarte w Instrukcji

    Salvage brachytherapy in combination with interstitial hyperthermia for locally recurrent prostate carcinoma following external beam radiation therapy: a prospective phase II study.

    Optimal treatment for patients with only local prostate cancer recurrence after external beam radiation therapy (EBRT) failure remains unclear. Possible curative treatments are radical prostatectomy, cryosurgery, and brachytherapy. Several single institution series proved that high-dose-rate brachytherapy (HDRBT) and pulsed-dose-rate brachytherapy (PDRBT) are reasonable options for this group of patients with acceptable levels of genitourinary and gastrointestinal toxicity. A standard dose prescription and scheme have not been established yet, and the literature presents a wide range of fractionation protocols. Furthermore, hyperthermia has shown the potential to enhance the efficacy of re-irradiation. Consequently, a prospective trial is urgently needed to attain clear structured prospective data regarding the efficacy of salvage brachytherapy with adjuvant hyperthermia for locally recurrent prostate cancer. The purpose of this report is to introduce a new prospective phase II trial that would meet this need. The primary aim of this prospective phase II study combining Iridium-192 brachytherapy with interstitial hyperthermia (IHT) is to analyze toxicity of the combined treatment; a secondary aim is to define the efficacy (bNED, DFS, OS) of salvage brachytherapy. The dose prescribed to PTV will be 30 Gy in 3 fractions for HDRBT, and 60 Gy in 2 fractions for PDRBT. During IHT, the prostate will be heated to the range of 40-47°C for 60 minutes prior to brachytherapy dose delivery. The protocol plans for treatment of 77 patients

    Applications of RFID technology in dismounted soldier solution systems – study of mCOP system capabilities

    No full text
    This paper discusses application of RFID technology in Dismounted Soldier Solutions gathered from the development and demonstration of mCOP platform. The software has been developed to elaborate Network Enabled Capabilities in tactical environments. Presented research was a part of demonstration prepared for the European Defence Agency. The main aim of the tool is the delivery of command support capabilities utilizing data fusion and integration mechanisms implemented in heterogeneous military mobile networks. Application of military integration standards such as JC3IEDM, NFFI and TSO supports interoperability with BMS class systems. Utilisation of RFID technology in mCOP software has several purposes, mainly used for process automation of authorisation and personal identification. Indirectly such functionalities can be used for implementation of UAV supported - Blue Force Tracking and IFF services. This research elaborates a set of implemented ideas for such solutions. Developed system serves as a multi-level and multi-platform command and control system supporting military and crisis operations. A crucial part of the system - mCOP, the handheld application for tactical level commanders, serves as personal toolkit for location monitoring and combat situation distribution and management. The tool delivers a set of tailored functionalities supporting commander’s situation awareness and decision making process. The mCOP hosting device equipped with RFID delivers also means of tactical , emergency, micro network communication

    Queue-based quantitative approach for border guard operational modelling. Constructive simulator models reflecting border crossings and blockade elements.

    No full text
    The paper presents selected modelling techniques utilised in constructive simulation environment SymSG Border Tactics which provides tactical training capabilities for Polish Border Guard. Operational responsibilities of BG include policing as well as reconnaissance, transport and traffic control in near border areas. Modelling of such operations require multiresolution approach, as many of operational elements can be modelled as aggregated entities but majority of active simulation elements need to be implemented as individual simulation objects. The behavioural models reflecting BG, perpetrators or society have been modelled as agents and more complex operational elements (e.g. road blockades, control points during temporary restoration of the border control, border crossing) are modelled using queue system. Such approach delivers flexibility of system modelling but most of all is tuned to the calibration parameters provided by the BG analysts. Therefore, developed modelling approach provides flexibility in customisation of the model (simulation element) based on the user and scenario preferences. Constructive simulator has been designed to support brief (up to 4h) live exercises and reflect training of border guard outpost operational tasks. Finally the paper describes architectural solutions developed to support modelling approaches and required functionalities for simulation execution, after-action-review mechanism and remote simulation access
