Finding the Curie Temperature for Ferromagnetic Materials
(The Physics Teacher, 2007-01) Kizowski, Czesław; Budzik, Sylwia; Cebulski, Józef
The laboratory exercise described in this paper is based on a well-known qualitative demonstration of Curie temperature.1 A long ferromagnetic wire, in the form of a spiral, is attracted to a strong permanent magnet placed near its midpoint (see Fig. 1). The temperature of the wire is increased by passing a current through it. When the temperature reaches the Curie point, the wire becomes paramagnetic and is no longer strongly attracted to the magnet. We have developed this demonstration into a quantitative experiment by providing an accurate way to determine the temperature at which the ferromagnetic-paramagnetic transition occurs.
How electromagnetic fields can influence adult stem cells: positive and negative impacts
(Stem Cell Research & Therapy, 2016-04-18) Maziarz, Aleksandra; Kocan, Beata; Bester, Mariusz; Budzik, Sylwia; Cholewa, Marian; Ochiya, Takahiro; Banas, Agnieszka
The electromagnetic field (EMF) has a great impact on our body. It has been successfully used in physiotherapy for the treatment of bone disorders and osteoarthritis, as well as for cartilage regeneration or pain reduction. Recently, EMFs have also been applied in in vitro experiments on cell/stem cell cultures. Stem cells reside in almost all tissues within the human body, where they exhibit various potential. These cells are of great importance because they control homeostasis, regeneration, and healing. Nevertheless, stem cells when become cancer stem cells, may influence the pathological condition. In this article we review the current knowledge on the effects of EMFs on human adult stem cell biology, such as proliferation, the cell cycle, or differentiation. We present the characteristics of the EMFs used in miscellaneous assays. Most research has so far been performed during osteogenic and chondrogenic differentiation of mesenchymal stem cells. It has been demonstrated that the effects of EMF stimulation depend on the intensity and frequency of the EMF and the time of exposure to it. However, other factors may affect these processes, such as growth factors, reactive oxygen species, and so forth. Exploration of this research area may enhance the development of EMFbased technologies used in medical applications and thereby improve stem cell-based therapy and tissue engineering.
NANOTECHNOLOGY AS A PART OF PHYSICS TEACHING AT SCHOOL
(Concepts of Physics, 2008-01) Budzik, Sylwia; Kizowski, Czesław
The progress in teaching should be in accord with the progress of science, that’s why the subject of teaching must be supplemented by the elements of modern knowledge which permit pupils to understand better what happens around us. The end of XX century is characterised by the rapid development of nanotechnology, which we deal with in this paper.
Nanotechnology elements in Science and Physics teaching at high school
(Wydawnictwo Uniwersytetu Rzeszowskiego, 2012-07) Budzik, Sylwia; Kizowski, Czesław
The progress in teaching should be in accord with the progress of science, that’s why the subject of teaching must be supplemented by the elements of modern knowledge which permit people to understand better what happens around us. The end of XX century is characterised by the rapid development of nanotechnology, which brings together various sciences such as solid state physics, chemistry, material science and molecular biology and gives a chance to the technological revolution. From the research, we conclude that the nanotechnology elements can be introduced on the 4-th educational stage (in Poland), where is the possibility to increase the use of mathematics. In 2012/2013 school year will be introduce new core curriculum into high school, where is new subject - Science (Core Curriculum – Science and Physics - law gazette from 2009, no. 4, pos. 17). Research, contained in this monograph, were connected with Science and Physics contents of teaching and proves possibility introducing new elements to the curriculum. Process concerning the introducing new elements to the curriculum, from the didactic base to the concrete lessons, is presented in this monograph. This monograph, in authors view, helps the Physics teachers with curriculum preparing based on the one - subject integration of teaching contents.

The progress in teaching should be in accord with the progress of science, that’s why the subject of teaching must be supplemented by the elements of modern knowledge which permit pupils to understand better what happens around us. The end of XX century is characterised by the rapid development of nanotechnology, which is deal with in this paper. Development of the science in the end of the XX century and at the beginning of the XXI century is presented in Introduction. The research problem, aims and base of doctoral thesis are presented in the first chapter. The second chapter is connected with project of solution, it means with the analysis of “teaching contents”. The operational aims, basic theorems and “didactic matrix”, which shows logical relations between nanotechnology elements are presented in this chapter. Pedagogical and psychological base of doctoral thesis is depicted in the third chapter. There is teenager characteristic – the age of pupils, when we can introduce this kind of concepts. The main quantum mechanics concepts are presented in third chapter too. The physical, psychological and pedagogical point of view formed the basis for research. Experimental part is contained in fourth chapter. General education system in Poland and 4th educational stage is high school as a level, where is the possibility to increase the use of mathematics are shown in the first subsection of fourth chapter. The second subsection of fourth chapter contains the survey for teachers results. There are concepts indicated by the teacher, which should be introduced to the curriculum of science subject in high school. The hypotheses and the methods used in the research are presented in the third subsection of the fourth chapter. Research conditions are indicated in the fourth subsection of the fourth chapter. There are taken into account the following categories: type of class, different backgrounds, average mark in a class. Preliminary research conclusions from all classes are shown in the fifth subsection of the fourth chapter and final research conclusions from all classes are shown in the sixth subsection of the fourth chapter. Conclusions from the doctoral thesis are in the last chapter. There is summary and deduction if the working hypothesis is proved. References, annexes (Physics core curriculum, survey for teachers, test for pupils, lessons, and agreement to the cooperation with schools) and author Curriculum vitae are at the end of this doctoral thesis.
