rodzaj: rozdział/fragment książki
Abstrakt: The flammability hazard of polymeric materials is an important issue in context of health and environmental risks, especially if nanomaterials are applied to modify polymer matrices. The use of nanoparticles can provide an increased fire resistance of polymer composites through char layer formation giving an effective barrier protection, labyrinth effect, and molecular mobility suppression; however, free nanoparticles (dry, dispersible single particles or agglomerates) may enter the gaseous phase during combustion processes, creating a risk as they may penetrate into the human body. Extensive research programs initiated to develop novel nanostructured flame retardants for polymeric materials have already shown some beneficial effects such as reduced heat release rate, reduced drip and improved self-extinguishing properties, and the formation of char residue on the surface of polymeric materials. However, the health and environmental hazards associated with the use of nanoparticles that may show cytotoxicity as fillers or flame retardants in combination with other flame retardants to obtain novel hybrid systems in polymeric materials should be taken into account, as possible accumulation of nanoparticles in the human body can lead to complex interactions with human cells and affect primarily both cardiovascular and respiratory systems.]]>
<![CDATA[Mechanical test and computer models for the evaluation of soft tissue parameters used in implants design]]> Sat, 16 Oct 2021 09:30:45 +0200 Liber-Kneć, Aneta; Łagan, Sylwia
rodzaj: rozdział/fragment książki
Abstrakt: In aim to good fitting biomaterials to implants, some major requirements should be met. These are the biocompatibility, bioinertity, bioreactivity, nonpirogenity and noncancerogenity. Some of these features have biological character but most of them have physicochemical basis. In this chapter, the mechanical properties of tissues and biomaterials will be described in terms of using them in computer modeling, which is often applied to predict their behavior in simulated conditions. This is the main task for biomedical engineers. The mechanical tests of biomaterials should be conducted with consideration of mechanical behavior of the biological tissues (hard and soft). These rules are important for proper design of the safe and strong implants. The conditions of tests conducted in laboratory should be similar to the body environment. There are some procedures as physical experiment, mathematical simulations and computer modeling, which can provide sufficient data for implant design process.]]>

<![CDATA[Badania przydatności nowych sensorów fluorescencyjnych do monitorowania fotopolimeryzacji za pomocą techniki FPT]]> Mon, 11 Oct 2021 11:11:02 +0200 Szymaszek, P.; Ortyl, J.
rodzaj: rozdział/fragment książki
Abstrakt: Technologia Sond Fluorescencyjnych (FPT) to niedawno opracowana metoda, która oferuje możliwość monitorowania procesów on-line polimeryzacji za pomocą odpowiednich fluorescencyjnych sond molekularnych, które zmieniają swoje właściwości fluorescencyjne w odpowiedzi na zmiany zachodzące w środowisku. W zależności od rodzaju monitorowanego procesu i monitorowanych parametrów wymagana jest odpowiednia struktura sondy. Dlatego też opracowanie nowych sond odpowiednich dla poszczególnych systemów wśród dostępnych fluoroforów jest ważna dla ich praktycznych zastosowań. W niniejszych badaniach opisano przydatność pochodnych 2-amino-4,6-difenylo-pirydyno-3-karbonitrylowych jako sond molekularnych do monitorowania fotoinicjowanej polimeryzacji wolnorodnikowej wielofunkcyjnych monomerów.]]>
<![CDATA[Badania nad przydatnością nowych niekowalencyjnych sensorów fluorescencyjnych do wykrywania biomakromolekuł w diagnostyce medycznej]]> Mon, 11 Oct 2021 11:00:40 +0200 Szymaszek, P.; Ortyl, J.
rodzaj: rozdział/fragment książki
Abstrakt: Przebadano niekowalencyjne oddziaływanie nowych pochodnych 2-amino-4,6-difenylopirydyno-3-karbonitrylu z albuminą surowicy bydlęcej (BSA) za pomocą metod spektroskopowych. W tym celu wykonano badania absorbancji i fluorescencji nowych pochodnych oraz ich interakcji z BSA. Wykazano, że nowe pochodne 2-amino-4,6-difenylopirydyno-3-karbonitrylu posiadają właściwości spektroskopowe umożliwiające ich potencjalne zastosowanie w roli sensorów fluorescencyjnych oraz wykazują pożądane parametry wiązania z BSA.]]>
<![CDATA[Multi-criteria decision-making system for design and implementation on the market rehabilitation toys]]> Thu, 07 Oct 2021 14:38:10 +0200 Korniejenko, Kinga; Harpak, Katarzyna
rodzaj: rozdział/fragment książki
Abstrakt: Currently, devices, toys used in the practice of children's rehabilitation cen-tres usually have simple forms and shapes, a monolithic form and are devoid of mechanical or electronic control systems. In practice, the use of interac-tive tools is rare and associated mainly with expensive and advanced solu-tions, such as rehabilitation robots and devices using virtual reality. Rehabili-tation centres mainly use simpler and cheaper devices. The design of this type of aid is usually simple according to technology, but quite complex to ensure full functionality for the rehabilitation purpose. A lot of aspects should be taken into consideration. The aim of this chapter is to analyze the possibility of using multi-criteria methods for support in the designing and implementation on the market rehabilitation toys. Multi-criteria methods used to support the decision-making process, are a response to the complexity of contemporary issues in conditions of uncertainty, incomplete data and changing environment. The research methods used in the article are: critical analysis of literature sources and the case study of the use of the Analytic Hierarchy Process (AHP) for implementation on the market rehabilitation toys.]]>
<![CDATA[Content and competency structure of IT specialties students in the field of bioengineering]]> Thu, 07 Oct 2021 13:38:41 +0200 Tarasov, Oleksandr; Sahaida, Pavlo; Tankut, Volodymyr; Vasylieva, Liudmyla; Korniejenko, Kinga
rodzaj: rozdział/fragment książki
Abstrakt: This lecture is devoted to the introduction of multidisciplinary training for the specialists in the field of design and implementation of high-tech implants with elements of intellectual behavior. The end-to-end process of designing such implants is considered: from the study and analysis of functional requirements, as well as the study of new materials, 3D-modeling of geometric parameters, and modeling of mechanical properties – to the development of electronic and software components of sensory and control subsystems. Identification of the main stages of implant development made it possible to identify and formulate the necessary competencies that need to be formed by specialists in this field. Students will be acquainted with the general direction of training, the skills, and abilities that they are going to acquire during the training. In the process of system analysis of the development of implants, an ontological approach was applied. It allowed formalizing the analysis results in a form convenient for the preparation of regulatory documents. Information support for the organizational and methodological work of teachers was also improved. This lecture also increases the students’ motivation to study disciplines of the bioengineering field. A competency-based approach to the organization of the educational process requires the development of an integrated model of educational processes and the objects that participate in them, based on high-level abstractions.]]>
