    Opis:
    In 2014 we finished research works involved in the development of a technology for manufacturing innovative ceramic-carbon foam filters for molten metal alloys filtration, which were financed by the National Centre for Research and Development (NCBiR) from INNOTECH programme resources. A batch of the filters produced in this technology was tested in practice in domestic cast steel and cast iron foundries. The trials were successful and foundries declared their intention to purchase the newly-developed filters for the current production of casts. This provided an incentive for “Ferro-Term” Sp. z o.o. to start design works on the prototype line for a serial production of these filters. At the same time, in co-operation with a scientific consortium, including the co-authors of the technology, i.e. the Institute of Ceramics and Building Materials, Refractory Materials Division in Gliwice, Institute for the Chemical Processing of Coal in Zabrze and Foundry Research Institute in Cracow, the company made a successful attempt to raise some funds for the necessary adaptation of the developed technology from the semi-technical to industrial scale from Intelligent Development Operational Programme. In the article we have presented information on the effects of works performed within the framework of the project entitled “Modernization and adaptation of the existing technological line for purposes related to technology verification and start-up of the production of innovative ceramic-carbon filters for molten metal alloy filtration”.

    Progress in technology and the demand for systems used for psychophysiological measurements, which record several synchronous parameter / signal types at a time, have a significant impact on the increasing number of innovative solutions available in the market. This article focuses on the design and engineering path of the created systems with special emphasis on the latest solutions, developed at the Institute of Medical Technology and Equipment (ITAM) in Zabrze. Competitive systems and other systems are also referred to by way of a comparative analysis, both in terms of their benefits and drawbacks. The overview shows that the new system may become a competitive solution for the already existing options and that it is characterized by a number of properties that make it unique.

    Opis:
    ITAM completed work on developing a prototype of the system designed to monitor and conduct cardiac rehabilitation at home. In the course of project execution, a number of devices have been made or adapted to work within the system. The primary problem to be solved was to develop a way of communication for these devices, which would allow the transmission of necessary data in a way that would be convenient for the patient and provide the staff supervising the patient with easy access to this data. Ensuring correct operation the system required a variety of cooperating transmission systems to be used. Communication within the apartment utilizes a wireless network based on a Bluetooth link. The parent node of this network is the Base Station, which is also an intermediary for communication between devices within the apartment and the Centre for Monitoring and Communications. The main module carried by the patient is the ECG module that, in addition to its measurement function, serves as a personal area network node based on elements of the ANT standard supporting the Messenger carried by the patient. This module is also tasked with supervising the patient outside the apartment, making communication with the Centre possible via a GSM/GPRS network. The Base Station exchanges information with the Monitoring and Communication Centre located on a server via the Internet. Access for the patient's doctor or support worker to the Monitoring Centre is possible from any computer with access to the Internet by logging onto the Centre's server.

    J-PET analysis framework is a flexible, lightweight, ROOT-based software package which provides the tools to develop reconstruction and calibration procedures for PET tomography. In this article we present the implementation of the full data-processing chain in the J-PET framework which is used for the data analysis of the J-PET tomography scanner. The framework incorporates automated handling of PET setup parameters' database as well as high level tools for building data reconstruction procedures. Each of these components is briefly discussed.

    Opis:
    A method for creating linearly polarized positrons and ortho-positronium (o-Ps) atoms with the J-PET detector is presented. The unique geometry and properties of the J-PET tomography enable one to design a positron source such that the quantization axis for the estimation of the linear polarization of produced o-Ps can be determined on the event by event basis in a direction of the positron motion. We intend to use ²²Na or other β⁺ decay isotopes as a source of polarized positrons. Due to the parity violation in the beta decay, the emitted positrons are longitudinally polarized. The choice of the quantization axis is based on the known position of the positron emitter and the reconstructed position of the positronium annihilation. We show that the J-PET tomography is equipped with all needed components.

    Opis:
    The Jagiellonian positron emission tomograph project carried out in the Institute of Physics of the Jagiellonian University is focused on construction and tests of the first prototype of PET scanner for medical diagnostic which allows for the simultaneous 3D imaging of the whole human body using organic scintillators. The J-PET prototype consists of 192 scintillator strips forming three cylindrical layers which are optimized for the detection of photons from the electron-positron annihilation with high time-and high angular resolutions. In this article we present time calibration and synchronization of the whole J-PET detection system by irradiating each single detection module with a ²²Na source and a small detector providing common reference time for synchronization of all the modules.

    Positron annihilation lifetime spectroscopy has shown to be a powerful tool to study the nanostructures of porous materials. Positron emission tomograph is a device allowing imaging of metabolic processes e.g. in human bodies. A newly developed device, the Jagiellonian PET will allow positron annihilation lifetime spectroscopy in addition to imaging, thus combining both analyses providing new methods for physics and medicine. In this contribution we present a computer program that is compatible with the Jagiellonian PET software. We compare its performance with the standard program LT 9.0 by using positron annihilation lifetime spectroscopy data from hexane measurements at different temperatures. Our program is based on an iterative procedure, and our fits prove that it performs as good as LT 9.0.
