Abstract

This paper elucidated the potential of electron backscatter diffraction analysis for ground granulated blast furnace slag geopolymers at 1000°C heating temperature. The specimen was prepared through the mechanical ground with sandpaper and diamond pad before polished with diamond suspension. By using advanced technique electron backscatter diffraction, the microstructure analysis and elemental distribution were mapped. The details on the crystalline minerals, including gehlenite, mayenite, tobermorite and calcite were easily traced. Moreover, the experimental Kikuchi diffraction patterns were utilized to generate a self-consistent reference for the electron backscatter diffraction pattern matching. From the electron backscatter diffraction, the locally varying crystal orientation in slag geopolymers sample of monoclinic crystal observed in hedenbergite, orthorhombic crystal in tobermorite and hexagonal crystal in calcite at 1000°C heating temperature.

Abstract

A serological study to detect antibodies against microbes in avian mycoplasmosis (Mycoplasma gallisepticum and M. synoviae), and salmonellosis (Salmonella gallinarum and S. pullorum) was carried out. A hundred and twelve Antarctic birds (42 Adelie penguins, Pygoscelis adeliae, 30 southern giant petrels, Macronectes giganteus and 40 skuas, Catharacta antarctica and C. maccormicki) from King George Island, the South Shetland Islands, and Laurie Island, the South Orkney Islands in Antarctica were studied. The serological test used in this study was a rapid agglutination test. According to the results and considering the number of samples analysed, it is reasonable to believe that Adelie penguins, southern giant petrels, and skuas populations of the areas mentioned above are free from mycoplasmosis and salmonellosis.

Abstract

The Department of Theology Section in Tarnów was established formally as a result of transformation of The Institute of Theology in Tarnów. This Institute was founded in 1822 for educating the clergy serving Tarnów diocese and its activities were always strongly connected to the Seminary in Tarnów. Since the communists took control over our country in 1945, the Institute existed only formally, but in fact, it was always identified with The Seminary in Tarnów.

Bishop professor habilitated doctor Józef Życiński, who was at that time the Tarnów bishop, transformed the Institute of Theology into the Theology and Pastoral Institute and strongly contributed to its aggregation to the Theology Department of the Pontifical Academy of Theology in Kraków in 1993. Since then, the graduates of the Institute have had the opportunity to obtain the MA degree in theology. Thanks to efforts of bishop doctor Wiktor Skworc, the Congregation of the Catholic Education established the Department of Theology Section in Tarnów of the Pontifical Academy of Th ology in Kraków (WTST) instead of the Institute.

In 2007 the Department of Theology Section in Tarnów obtained the rights to confer a PhD degree in theology. Since the aggregation of the Institute of Theology Section in Tarnów to the Theology Department of the Pontifical Academy of Thology, about 90 to 100 students receive their MA degrees annually. Approximately, half of this group consists of the secular and another half of the monastic. Since the beginning, the number of secular candidates accepted, has always been limited. There are the following profiles to choose from: sacerdotal, pastoral and catechetical, social and charity.

The scientific journal of the Department is „Tarnowskie Studia Teologiczne” – „Tarnów Theology Studies” issued half a year.
