Faculty of Physics and Applied Informatics, University of Lodz, ul. Pomorska 149/153, 90-236 Lodz, Poland; Punsiri Dam-o was born in Nakhon Si Thammarat, Thailand in 1981 and was raised by her parents: Nuhein and Paur, with her elder sister and brothers: Wissawan, Chalermpol and Pinij. When growing up, she gained a good appreciation for the natural world through going on forest, mountain and sea trips with her late father*. Her interest in science began back in High School at the Princess Chulabhorn’s College Nakhon Si Thammarat (PCC NST), where she became involved in various scientific activities. These included conducting an Environmental Conservation Club. It was there she found herself enjoy teaching her friends in physics, with the advice and guidance of her teacher: Suwanij Julawat. From there Punsiri then decided to attend the Physics Education Program at the Prince of Songkhla University (PSU), Pattani Campus. She went on to spend the summer of her senior year teaching physics to pupils in Southern Thailand. She graduated from PSU with a B.Sc. degree in Physics Education with honors back in 2002. On graduation she started her career as a physics teacher at PCC NST. After teaching at the school for one year, she then decided to leave there to continue her own education, enrolling on the M. Sc. degree in Physics Studies at Walailak University (WU). Once there Punsiri worked in the lab of dr. Ketsiri Kueseng** and assist prof. dr. Kowit Kittiwutthisakdi as a graduate student, working in the field of development of atomic and molecular modeling as part of the fundamental science curriculum. This included studying the properties and behaviours of water molecules and also the development of physical models of functional groups in molecules. After obtaining the M.Sc. degree, she worked as a physics lecturer at the university (WU) for a number of years and was then promoted to be a Ph.D. degree scholarship recipient. The Ph.D. degree scholarship is awarded by the Ministry of 156 Science and Technology in Thailand. Having received the scholarship she then moved to Poland to study physics at University of Łódź and worked in the lab of prof. dr hab. Tadeusz Wibig, as a doctoral student in the field of remote laboratories for educational physics: interactive wind tunnel and x-ray spectroscopy labs, from the fall of 2009.; punsiri.pla@gmail.com |

| Description: |
PhD thesis of mgr Punsiri Dam-o is dedicated to studies of the heavy metal pollution in samples of biological origin using the X-ray spectroscopy technique. The thesis contains the 156 pages, is preceded by a table of contents, list of figures and tables. It consists of eight chapters, two appendices, a bibliography containing almost 70 items, acknowledgments and a short CV on last two pages. In the first introductory chapter mgr Punsiri Dam-o describes the origin of the project which is an essential part of her work and its importance from the physical and socio-educational points of view. In the next chapter she discusses the sources of heavy metals pollutants characteristic to the human activity analysed in this work. In the third chapter she shows the current state of research in this field and results obtained by other authors experiments and results characteristic of specific plants to justify the selection of species made in the work. In the third chapter there is described the method of collecting and preparation of samples and the measuring technique using the X-ray fluorescence spectrometer with the particular method of analysis obtained spectra involving high school students participating in the project. Next chapter is dedicated to the problem of obtaining non-professional forces to project activities. There is described the structure of the webpage of the "nuclear e-cology" project, its functioning and problems associated with such a kind of scientific activity. The fifth chapter presents the physical results obtained and their general overview, and the sixth summarizes them in five short and specific statements. The results are divided into two classes: the first is the analysis of the total contents of heavy metals in the vicinity of the roads and there is shown the significant achievement of this work consisting of the discovery of the significant dependence of the pollution levels with time elapsed from a particular road construction; and the second is the examination of the rate of decrease of ... |
