Investigation of the temperature dependence of free volume in polymethylpentene by positron annihilation method

Positron lifetime measurements in polymethylpentene were performer in a wide temperature range. A conventional fast-slow coincidence lifetime spectrometer with plastic scintillators was used. All the measurements were made in vacuum. Additional measurements (X-ray diffraction, differential scanning calorimetry, and mechanical spectroscopy) were also performed to establish properties of samples. Mean free volume radii in the investigated samples were estimated from the positron lifetimes measurements results. An increase in I3 with the elapsed time of measurements was observed

No Refuge: Hungarian Romani Refugee Claimants in Canada

From 2008 to 2012, thousands of Hungarian Roma sought asylum in Canada. Some political actors suggested that their claims were unfounded and demonstrated that Canada’s refugee processes were vulnerable to abuse. In contrast, advocates for refugees argued that persecution against Roma was rampant in Hungary and noted that hundreds of Hungarian Roma were granted refugee status in Canada. Much of this debate has occurred in an evidentiary vacuum. This article fills this vacuum through a qualitative and quantitative study of Hungarian Romani refugee claims. First, the context of the study is discussed. Then, the article explores the experiences of Hungarian Roma within Canada’s refugee determination system between 2008 and 2012. The article ends with concluding remarks, focusing on particularly troubling findings from the study, including the impact of anti-refugee rhetoric, institutional bias, inconsistent decision making, and problems related to quality of counsel

No Refuge: Hungarian Romani Refugee Claimants in Canada

From 2008 to 2012, large numbers of Hungarian Romani refugee claimants came to Canada. Their arrival was controversial. Some political actors suggested that their claims were unfounded and amounted to abuse of Canada’s refugee processes -- abuse which could only be prevented through wide-scale reforms to the refugee determination system. Many advocates for refugees, by contrast, argued that persecution against Roma was rampant in Hungary and noted that hundreds of Hungarians had been recognized as refugees in Canada. Some went further and contended that Romani refugee claimants fled persecution in Hungary only to be confronted with similar mistreatment in Canada. Unfortunately, much of the debate about Hungarian Romani refugee claims in Canada has occurred in an evidentiary vacuum. The purpose of this article is to fill this vacuum by setting out the results of a quantitative and qualitative empirical study of Hungarian Romani refugee claims. The article begins by discussing the context of the study, offering an overview of the historic and contemporary experience of Roma in Hungary and outlining the history of Hungarian Romani migration to Canada, including two recent streams of migration by Hungarian Romani refugee claimants and Canada’s response to these claimants. The article then moves on to an empirical study about the experience of Hungarian Romani with Canada’s refugee determination system between 2008 and 2012. Finally, the article offers concluding remarks, focusing on several particularly troubling findings from the study, including the impact of anti-refugee rhetoric, concerns about institutional bias and inconsistent decision making at the Immigration and Refugee Board, and problems related to quality of counsel

Influence of temperature and pressure on the free volume in thermo-shrunken polyethylene by positron annihilation

Positron lifetime measurements were performed as a function of temperature and pressure for thermo-shrunken polyethylene. Mean volume of free volume cavities in the investigated polymer was estimated from the results of the measurements. This mean volume turned out to be the smooth function of temperature (from room temperature to 8.5 K) and high pressure (from 0.1 MPa to about 500 MPa). The effect of trapping of the free electrons produced during positron irradiation was observed at low temperature

"Sucha Góra" ("Trockenberg") - The Triangulation Point Doomed to Be Forgotten?

The current study documents the importance of research on preserved artifacts which were previously used to take measurements of the Earth, and their importance for cultural heritage. The article reviewed the available source documents presenting the history of the astrogeodetic control point of Sucha Góra-Trockenberg as a monument of the first order triangulation network, preserved in cartographic materials and as the starting point of local geodetic networks, used in mining until 2000 in the so-called Upper Silesian Coal Basin, located in the territory of Poland and the Czech Republic. In order to determine the history of the triangulation work and the dates that the geographic coordinates of the peak were determined, field journals and other available materials were analyzed. The interesting location of this astrogeodetic control point, being in the vicinity of a UNESCO site, as well as its location in a forest and park complex, justify undertaking activities related to the conservation and promotion of this cultural heritage site
