Analysis of the Degradation of Pearlitic Steel Mechanical Properties Depending on the Stability of the Structural Phases.

The paper is focused on analysing the pearlitic steel phase transformations and their influence on the mechanical properties. The intention is to perform a detailed analysis of the heat treatment process using the exact heating temperature and chemical composition to achieve the optimal mechanical properties of the tool. The key area is monitoring and regulating the heat treatment. This technology is constantly undergoing an optimisation process and is an effort to introduce new trends in monitoring phase transformations and processes. The use of non-destructive methods is an adequate tool. The principle is to determine the exact structural phase at a given moment, which can be very difficult when a complex shaped part is heat treated. Which precludes the use of some other methods of phase transformation analysis. Specifically, the determination of the exact moment of finish of the austenitisation process is eminent. The monitoring of these processes will be ensured by both a non-contact pyrometer and also by the AE method with an adequate sensor and waveguide. The resulting structural phases formed after the heat treatment will be evaluated by electron microscopy, followed by the analysis of the mechanical properties of selected steels.

Rheological and Pipe Flow Properties of Chocolate Masses at Different Temperatures.

Chocolate masses are one of the basic raw materials for the production of confectionery. Knowledge of their rheological and flow behaviour at different temperatures is absolutely necessary for the selection of a suitable technological process in their production and subsequent processing. In this article, the rheological properties (the effect of the shear strain rate on the shear stress or viscosity) of five different chocolate masses were determined-extra dark chocolate (EDC), dark chocolate (DC), milk chocolate (MC), white chocolate (WC), and ruby chocolate (RC). These chocolate masses showed thixotropic and plastic behaviour in the selected range of shear rates from 1 to 500 s-1 and at the specified temperatures of 36, 38, 40, 42, and 44 °C. The degree of thixotropic behaviour was evaluated by the size of the hysteresis area, and flow curves were constructed using the Bingham, Herschel-Bulkley and Casson models with respect to the plastic behaviour of the chocolate masses. According to the values of the coefficients of determination R2 and the sum of the squared estimate of errors (SSE), the models were chosen appropriately. The most suitable models are the Herschel-Bulkley and Casson models, which also model the shear thinning property of the liquids (pseudoplastic with a yield stress value). Using the coefficients of the rheological models and modified equations for the flow velocity of technical and biological fluids in standard piping, the 2D and 3D velocity profiles of the chocolate masses were further successfully modelled. The obtained values of coefficients and models can be used in conventional technical practice in the design of technological equipment structures and in current trends in the food industry, such as 3D food printing.

Evidence-based position paper on the professional practice of Physical and Rehabilitation Medicine for persons with cerebral palsy. The European PRM position (UEMS PRM section).

Cerebral palsy (CP) is a group of the most common developmental disorders affecting movement and posture of the body, causing activity limitations and participation restrictions. The motor disorders of persons with CP are often accompanied by disturbances of sensation, cognition, communication and perception. The symptoms of CP are very diverse and persons with CP are usually presented with a mixed type of symptoms. The non-progressive disturbances can be attributed to disorders that were developed during pregnancy, birth and/or infant stage. The aim of this study was to improve physicians' professional practice of Physical and Rehabilitation Medicine for persons with cerebral palsy in order to improve their functionality, social and community integration, and to reduce activity limitations and/or participation restrictions. A systematic review of the literature including an 18-year period and consensus procedure by means of a Delphi process was performed and involved the delegates of all European countries represented in the Union of European Medical Specialists Physical and Rehabilitation Medicine (UEMS PRM) Section. As the result of a Consensus Delphi procedure, 74 recommendations are presented together with the systematic literature review. The PRM physician's role for persons with cerebral palsy is to lead and coordinate the multiprofessional team, working in an interdisciplinary way. They should propose and manage the complex but individual PRM program developed in conjunction with other health professionals, medical specialists and importantly in agreement with the patient, their family and care giver. This should be, according to the specific medical diagnosis to improve patients' health, functioning, social and education status, considering all impairments, comorbidities and complications, activity limitations and participation restrictions. This evidence-based position paper is representing the official position of The European Union through the UEMS PRM Section and designates the professional role of PRM physicians in persons with cerebral palsy.

Evidence based position paper on Physical and Rehabilitation Medicine (PRM) professional practice for ageing people with disabilities. The European PRM position (UEMS PRM Section).

Ageing people with disabilities (APwDs) are faced with challenges of ageing which is straightforwardly related to disability that adds to the burden related to their early-onset disability. The aim of the paper is to improve Physical and Rehabilitation Medicine (PRM) physicians' professional practice for APwDs (as a distinct group from those who are disabled due to the ageing process) in order to promote their functioning properties and to reduce activity limitations and/or participation restrictions. A systematic review of the literature and a Consensus procedure by means of a Delphi process have been performed involving the delegates of all European countries represented in the UEMS PRM Section. The systematic literature review is reported together with the 30 recommendations resulting from the Delphi procedure. The professional role of PRM physicians in relation to APwDs is extending, expanding and/or improving health-related rehabilitation services worldwide in various settings (getting beyond the rehabilitation facilities) emphasizing the concept of integrated care with collaboration across other sectors to meet the specific needs of APwDs. This evidence based position paper (EBPP) represents the official position of the European Union through the UEMS PRM Section and designates the professional role of PRM physicians in APwDs.
