Comenius University Supports YOUNG RESEARCHERS

pr@uniba.sk — Thu, 28 Apr 2022 12:31:00 +0200

The university received 430 grant applications and decided to support 222 of them with an average amount of 980 euros per project. As before, most grant applications came from PhD researchers from the Faculty of Natural Sciences, the Faculty of Mathematics, Physics and Informatics and the Faculty of Medicine. One of the selected projects studies the preparedness of physics teachers to meet the current goals of physics education. Silvia Novotná from the Faculty of Mathematics, Physics and Informatics plans to design an improved method of teaching physics in Slovakia. She will use observation of and interviews with teachers to develop their typology and design a specific way of teaching for each category. Her research should help inform the preparation of future physics teachers. Another grant recipient, Lukáš Kurinec from the Faculty of Management, studies how general practitioners manage patients and their health care expenses. "In this project, we are examining the impact of redundant referrals by GPs to specialists on healthcare costs," explains Kurinec. The project will propose a system of bonuses for GPs tied to how well they approach this issue. Kristína Mocsári from the Faculty of Education is testing a new, foreign therapy for pre-school and younger school-age children who stutter. In her project, she plans to test the therapy for six months. By comparing the results of entry, mid-point and final tests she plans to see whether the therapy helps reduce stuttering in children. "If the new therapy proves successful, it could help speech therapists across Slovakia," says Kristína Mocsári. Karin Černickaja from the Faculty of Social and Economic Sciences proposed a project to collect and analyse the life-stories of adults with learning disabilities or attention disorders. These stories are intended to serve future psychologists or other assisting and teaching professions. They will form a tool for mitigating stigmatization, raising awareness about this issue and also provide a source of inspiration for people with learning disabilities or attention disorders and for the general public. One of the potential markers of the severity of a COVID-19 case is the enzyme butyrylcholinesterase. Its physiological function has not yet been sufficiently researched. It is present in large amounts in our bloodstream and in most organs and is involved, among other things, in the metabolism of fats and the onset of obesity or cardiovascular diseases. Since the latter are risk factors increasing the severity of a COVID-19 infection, Lucia Markusková from the Faculty of Pharmacy wants to see if using this enzyme helps more easily identify the patients with a risk of a severe course of COVID-19 in order to improve the efficiency of their treatment. "The diversity of our PhD’s research projects mimics the university's broad scientific focus. Comenius University grants are meant to support the research that our students will use in their dissertations. I am pleased that we are able to continue this tradition and that this support meets with great interest every year," says Comenius University Rector Marek Števček.

MARIA-VICTORIA SCHISTAD: WE HOPE TO GO HOME ONCE THE WAR IS OVER

nasa.univerzita@uniba.sk — Tue, 26 Apr 2022 10:22:00 +0200

The Congress Centre in Modra – Harmónia is situated in a scenic and laid-back area of the Little Carpathians mountain range, only 25 km (15.5 mi) from both Bratislava and Trnava. Now it became a temporary home to a number of refugees from Ukraine. Maria-Victoria is one of them. She and her mother fled to Slovakia, but her father and uncle couldn’t. At the moment, no one in her family is serving in the armed forces of Ukraine, but her cousin Konstantin helps the army as a civilian. She knows many people who also fled the country and ended up in cities all around Europe. Most of her friends and relatives, however, remained in Ukraine – staying in towns which are safer than Kyiv, like Lviv, Khmelnytskyi, Ternopil or Uzhhorod. She and her mom are the only ones who left Ukraine. „My two grandmothers stayed in Kyiv, as did other members of my family. My two grandmothers are very old, one of them can't even stand up anymore. My cousin Anastasia and aunt Anna are taking care of them and don't want to leave," she explains. At the time of our interview, she and her mother had only been in Slovakia for thirteen days. What does it feel like to be suddenly in a foreign country? „It is hard. You leave the country where you spent your life, where you have work, family and friends, and it ́s so hard to go somewhere else and end up in a place where you suddenly don ́t have anything. I am here, my family is in Kyiv, and it is so scary that I cannot see them. We text each morning and they tell me that they are ok. We support each other and we know that everyone is fine." A Future Journalist? Her difficult fate notwithstanding, Maria-Victoria remains incredibly positive and always has a smile on her face. Her plan is to study at Comenius University. She can study in English but she also wants to learn Slovak. „I want to stay here and attend the university, so I will try and learn the language. My mum is trying to find a job in Slovakia, but she speaks neither English, nor Slovak. We don ́t know how long the war in our country will last, but we hope to go home once the war is over." Maria-Victoria wants to study journalism and work as a PR manager or just work in communication or advertising in general. Her dream job is to work for a PR agency. She is fluent in Russian and English in addition to her native Ukrainian. „In Ukraine I attended the National Aviation University in Kyiv and studied journalism and PR communication in the first year. I don ́t know whatʼs going on there now," continues Maria-Victoria. Humble despite the hardship Although her life is extremely difficult at the moment, Maria Victoria tries to stay positive despite the hardship. She still hopes that everything will be fine and that she can return home to reunite with her family when the war ends. During our conversation, she smiles constantly. Smile never leaves her lips, even as my own eyes well with tears. When I ask her how we can help the Ukrainians affected by the war, she answers humbly: „I think that right now I have everything I need. Your support matters a lot. We just need to know that you are here for us. In Bratislava, I saw many Ukrainian flags and banners with 'Glory to Ukraine' written on them. I have already made friends in Modra, it ́s great to laugh with them and talk about our situation. This is also a form of help and I think you are doing a lot," concludes Maria-Victoria.

Seminar of Graph Theory - Pavol Jánoš (28.4.2022)

Martin.Skoviera@fmph.uniba.sk — Tue, 26 Apr 2022 10:03:00 +0200

Pavol Jánoš (STU Bratislava):
On near-cages from lifts of dipoles
Abstrakt:
The problem of finding $(k,g)$-cages, that is, finding the smallest (in terms of the number of vertices) $k$-regular graphs of girth $g$ is largely open. One of the approaches of finding small graphs with given properties are lifting constructions. In this talk we examine our constructions of small $k$-regular graphs of girth 6 and 8, obtained by lifting dipoles and achieving the order of existing graphs of the corresponding girth. We also discuss another construction based on groups, called $G$-graphs, and show under which circumstances the $G$-graphs can be obtained as lifts of dipoles. This work is joint with Š. Gyürki, J. Šiagiová and J. Širáň

The Best University in the SCImago Ranking

pr@uniba.sk — Thu, 28 Apr 2022 12:42:00 +0200

The Slovak Academy of Sciences ranks first in Slovakia, while ranking 511st overall. It is followed by Comenius University Bratislava which placed 573rd overall. Universities are institutions which perform teaching in addition to research. The universities which reached the top quartile (25%) of the ranking all published their research in the most influential scientific journals, including Comenius University. The SCImago ranking evaluated 4364 universities according to three sets of indicators, based on research performance (50%), innovation outputs (30%) and societal impact measured by their web visibility (20%). The current edition of the ranking measures the indicators for the period of 2016-2020. The Scimago Institutions Rankings (SIR) is unique in that it does not focus only on university-type organizations, but also includes other relevant scientific and research institutes. The SIR uses the SCOPUS abstract and citation database, which means that it gives a better representation to humanities than, for example, the Shanghai ranking. The aim of the project was not to create a ranking like THE, QS or ARWU, but to serve as a basis for comparing entities in the fields of research activity, innovation and visibility on the Internet.

The Faculty of Education Unveils its Renovated Premises

pr@uniba.sk — Thu, 21 Apr 2022 10:07:00 +0200

The building in Šoltésova street will gain six new teaching rooms and seven new offices for teachers in an attic conversion and a new extension. The new space will include two kitchenettes and toilets. The renovation took longer than planned because the building is located in the listed area of the Old Town, and because of the pandemic. Construction was completed in 2020 but the building only obtained its permit for use on 29 September 2021. At the moment, the building is already used for teaching. The Faculty of Education also boasts a newly renovated entry area in its Račianska Street building. The entrance was modified in accordance with an overall strategy of Comenius University to make all its premises barrier-free. There is now an access ramp and a new sidewalk, the entrance door was replaced, the entry terrace repaired, interior decoration refreshed and a rest area created. The work was completed in February 2021 and the permit for use was obtained in the past October. The approval process was delayed by the need to obtain a permit to remove a thuja growing in a built-in pot, which was replaced by two new trees. The city council had to give its approval to plant the trees on its land because the faculty had no suitable property itself.

Seminar of Graph Theory - Jozef Rajník (21.4.2022)

Jozef Rajnik:
On d-dimensional nowhere-zero r-flows on a graph Abstract:
A d-dimensional nowhere-zero r-flow on a graph G, an (r,d)-NZF for short, is a flow where the value on each edge is an element of R^d whose norm lies in the interval [1,r-1]. Such a notion is a natural generalization of the well-known concept of circular nowhere-zero r-flow (i.e. d = 1). In this paper, we mainly consider the parameter \phi_d(G), which is the minimum of the real numbers r such that G admits an (r,d)-NZF. For every bridgeless graph G. The 5-flow Conjecture claims that \phi_1(G) <= 5, while a conjecture by Kamal Jain suggests that \phi_d(G)=1, for all d >= 3. Here, we address the problem of finding a possible upper-bound in the case d = 2. We show that, for all bridgeless graphs, \phi_2(G) <= 1 + \sqrt{5} and that the oriented 5-Cycle Double Cover Conjecture implies \phi_2(G) <= \Phi^2, where \Phi is the Golden Ratio. Moreover, we discuss some connections between this problem and some other well-known conjectures. Finally, we focus our attention on the cubic case: we propose a geometric method to describe an (r,2)-NZF of a cubic graph in a compact way, and we apply it in some instances.
