Hyperfine interactions in RxGd1- xFe3 intermetallics R = Tb, Y

The structural and magnetic properties of rare earth iron intermetallic compounds TbxGd1-xFe3 and YxGd1-xFe3 (x = 0. 0, 0. 1, 0. 2, 0. 4, 0. 5, 0. 6, 0. 8, 1. 0) was studied by X-ray diffraction, the 57Fe Mössbauer effect and SQUID measurements. All investigated compounds crystallize in the rhombohedral PuNi3-type of crystal structure. The investigation of magnetic properties of RxGd1-xFe3 proved their ferrimagnetic behavior. The Curie temperature of the investigated compounds decreases with the increase of R concentration from 721K (GdFe3) to 655K (TbFe3) and 533K (YFe3). The saturation magnetic moment MS in the RxGd1-xFe3 system increase with x parameter. The Mössbauer spectra are analyzed using four sextets, corresponding to three crystallographically (b, c, h) and four magnetically (b, c, h1, h2) inequivalent sites for iron. The mean hyperfine magnetic field increases with increase of the Gd concentration

Pandemic changes in work, rest, physical activity and diet versus nutritional status of respondents

The aim of the study was to determine how the COVID-19 pandemic affected the nutritional status of the respondents through changes in work mode, physical activity and diet among residents of the Tarnów region. Material and methods. The study was conducted using the diagnostic survey method, and the tool was the author's questionnaire. The study was conducted in January-February 2022, using the Google Forms platform. In total, data were collected from 414 people. The questionnaires were filled out mostly by women (67.9% vs. 32.1%). The average age of respondents was 31.9 years (±13.52). Results. Those who worked remotely and in hybrid mode had the highest percentages declaring an increase in food intake during the COVID-19 pandemic (65.0% and 59.7%, respectively). The highest percentages of those who indicated a deterioration in the quality of their food intake were those who worked remotely (60.0%) and hybrid job (45.5%), while those who did not work were the group that most often among the others indicated an improvement in the quality of their food (23.4%). Respondents with remote and hybrid jobs were the most likely to report a reduction in their activity level (72.5% and 58.4%, respectively). Considering the BMI of those surveyed before the COVID-19 pandemic and now, there is an apparent decrease in the percentage of those with a normal BMI in favor of overweight and obesity. Conclusions. During the COVID-19 pandemic period, the percentages of overweight and obese people increased. People working remotely and in hybrid mode not only increased the amount of food they consumed, but also began to consume lower-quality products, as well as more often reporting reduced levels of physical activity

Polish paralympic sports in the opinion of athletes and coaches in retrospective studies

The study aimed to identify the limitations observed in Polish Paralympic sport depending on the environment in which athletes train on a daily basis. The study included 581 persons divided into two basic groups. The first group consists of athletes (n = 324) and coaches (n = 88) appointed to the national team by associations and unions providing sports training exclusively for athletes with disabilities. The second group consisted of athletes with disabilities (n = 146) and their coaches (n = 23), who work in national sports associations working for both able-bodied and disabled people. The study used the diagnostic survey method with a questionnaire developed by Sobiecka. The difficulties indicated by the respondents referred to various aspects related to the activity in professional sport. Particularly emphasised difficulties were related to organizational and financial limitations as well as the management and coaching staff. At the same time, it was demonstrated that the environment was a differentiating factor between the studied groups of athletes and coaches

Electric relaxation and Mn3+/Mn4+ charge transfer in Fe-doped Bi12MnO20-BiMn2O5 structural self-composite

Fe-doped Bi12MnO20–BiMn2O5 ceramics was sintered at 1130 K for 6 h in ambient air. Two centro-symmetric phases formed thermodynamically stable self-composite material that was deduced from X-ray pattern analysis. The lattice parameters were a = 10.147(8) Å—for the cubic I23 Bi12MnO20 phase; and a = 7.545(4) Å, b = 8.538(1) Å, c = 5.758(3) Å—for the orthorhombic Pbam BiMn2O5 phase. The 57Fe Mössbauer spectrum, recorded at room temperature, has shown pure electronic quadrupolar split. The major doublets reflected the occurrence of Fe3+ ions distributed in two sites, i.e., octahedral Fe4+O6 and square pyramidal Fe3+O5, with preferential occupation of the pyramidal sites, that was consistent with the Pbam phase symmetry. The third doublet resulted from the presence of iron Fe3+ in tetrahedral Fe3+O4 coordination and corresponded to a small admixture of the I23 phase. The DC resistivity ρDC(T) dependence on temperature has shown thermally activated features, and the value of Ea,DC varied in the range of 0.22–0.37 eV. The electric impedance was measured in the f = 20 Hz–1 MHz and 100–690 K range. Two electrical relaxations were determined using the electric modulus formalism M″(T). Low-temperature relaxation has shown the temperature-dependent activation energy EA,1 = 0.14–0.20 eV and characteristic time values of τ01 = 10−10–10−12 s in 100–200 K range. It was attributed to the charge transfer between Mn4+/Mn3+ sites. The other relaxation occurred in the 170–220 K range, and it exhibited the following values: τ02 = 10−11 s, and EA,2 = 0.27 eV. A disorder-related VRH polaron model was proposed for ρDC(T) and for electric relaxation processes

Mechanical thrombectomy in acute stroke – Five years of experience in Poland

Objectives Mechanical thrombectomy (MT) is not reimbursed by the Polish public health system. We present a description of 5 years of experience with MT in acute stroke in Comprehensive Stroke Centers (CSCs) in Poland. Methods and results We retrospectively analyzed the results of a structured questionnaire from 23 out of 25 identified CSCs and 22 data sets that include 61 clinical, radiological and outcome measures. Results Most of the CSCs (74%) were founded at University Hospitals and most (65.2%) work round the clock. In 78.3% of them, the working teams are composed of neurologists and neuro-radiologists. All CSCs perform CT and angio-CT before MT. In total 586 patients were subjected to MT and data from 531 of them were analyzed. Mean time laps from stroke onset to groin puncture was 250±99min. 90.3% of the studied patients had MT within 6h from stroke onset; 59.3% of them were treated with IV rt-PA prior to MT; 15.1% had IA rt-PA during MT and 4.7% – emergent stenting of a large vessel. M1 of MCA was occluded in 47.8% of cases. The Solitaire device was used in 53% of cases. Successful recanalization (TICI2b–TICI3) was achieved in 64.6% of cases and 53.4% of patients did not experience hemorrhagic transformation. Clinical improvement on discharge was noticed in 53.7% of cases, futile recanalization – in 30.7%, mRS of 0–2 – in 31.4% and mRS of 6 in 22% of cases. Conclusion Our results can help harmonize standards for MT in Poland according to international guidelines

Metaphors in modern medical language

Medycyna, zarówno sama nauka jak i jej język wzbudzają zainteresowanie wśród badaczy i językoznawców. W niniejszej pracy definiujemy współczesny język medyczny i wymieniamy jego cechy. Opisujemy również pojęcie metafory, opierając się na teorii kognitywnej, do której odwołujemy się w trakcie naszych badań. Nasza praca ma na celu potwierdzenie istnienia metafor w języku medycznym, a także określenie roli jaką odgrywają one w relacji lekarz-pacjent. W tym celu zebraliśmy wszystkie przypadki znalezione w publikowanych artykułach z konkretnego, specjalistycznego czasopisma medycznego. Metafory zostały sklasyfikowane według różnych typów a ta, która wyróżnia się spośród innych ze względu na dużą ilość znalezionych przykładów, to metafora wojenna. Praca ta opisuje również przykłady innych rodzajów metafor obecnych w języku medycznym. Używanie metafor w języku medycznym ułatwia zrozumienie specjalistycznej terminologii, która stanowi nieodłączny element współczesnej medycyny.The science and language of medicine generate great interest among both researchers and linguists in this field. In this thesis, we define modern medical language and consider especially its linguistic features. We also investigate the concept of metaphor, based on cognitive theory, which we refer to during our studies. Our thesis is aimed at demonstrating the existence of metaphors in medical language, as well as defining the role they play in the doctor-patient relationship. For this purpose, we have collected all the cases found in published articles from a specific medical journal. Metaphors have been classified according to different types, and the one that stands out from others because of the large number of examples found is the metaphor of war. This thesis also describes examples of other types of metaphors present in medical language. The use of metaphor in medical language is helpful to assist understanding of the specialized terminology which is an inherent feature of modern medicine.La medicina, en tanto como una rama de la ciencia como su lenguaje, despierta interés entre investigadores y lingüistas. En este trabajo, definimos el lenguaje médico actual y enumeramos sus características lingüísticas.

Mineralogical characteristics of metallic phases in copper slags from the Old Copper Basin, Poland

Metallic phases (sulphides, metallic compounds and metals), constitute critical components of metallurgical slags as they concentrate most of the potentially toxic metals occurring within smelting wastes. For this reason, a detailed characterization of the metal-rich phases is crucial for proper estimation of environmental threat resulting from slags deposition. Metallic phases observed in slags were transformed from the original ore minerals during metal smelting, and they constitute an interesting field for observations of sulphides and metals susceptibility to temperature and chemistry changes. In this study, we observed that compositions similar to sulphide minerals (e.g. bornite, chalcocite, pyrrhotite) are common, but they always appear in specific sets. We distinguished 3 general types of metallic phases: copper-iron-sulphur (among which the following subtypes appear: bornite-pyrrhotite, chalcocite, and chalcopyrite, all ofthese with various exsolutions), metallic copper and iron-phosphorous (Fe-P) type. Among all the distinguished types, Fe4Pproved to be most resistant to weathering whereas the Cu-Fe-S assemblage was altered strongly when not surrounded by glass or crystalline phases. Observations revealed that iron-rich metallic phases tended to appear in amorphous slags and copperrich phases occurring within crystalline samples

Blood donation during the coronavirus pandemic

Introduction: Despite years of research and scientific work, it has not yet been possible to produce such a valuable medication as blood. The pandemic does not reduce the need for blood, quite the opposite. However, due to the pandemic, the number of blood donors has dropped dramatically across the country. The aim of the study was to find out the opinions and attitudes of the respondents towards blood donation during the pandemic period and to assess their knowledge of the principles related to safe blood donation during this period.Material and methods: The study was conducted using a diagnostic survey method and the tool was our own research questionnaire. The study was conducted in February 2021, using Google Forms platform. In total, data were collected from 150 individuals (females: 60.6%, males 39.4%) aged between 16 and 73 years (mean 31.4 ± 12.4 years). Statistical analyses used a significance level of p = 0.05.Results: Nearly 39.7% of the respondents were regular blood donors, 12% of the respondents donated blood several times (12.3%). Blood was donated more often by men, people aged over 30 years, urban residents, and people with higher education (p < 0.001). Most people continued to donate blood despite the COVID-19 pandemic (49.7%). Respondents who have donated blood so far still mostly want to donate blood after the pandemic (90%), among those who have not done so 38% want to do so after the pandemic (p < 0.001). The vast majority of respondents believed it was safe to donate blood during the pandemic (93%), and most were aware that symptoms of infection disqualify a blood donor (83.2%). Only 43.2% knew that “Convalescents who donate plasma are entitled to a blood donation deduction”.Conclusions: The current pandemic situation is not an obstacle to donating blood. Blood donations should not be withheld unless there are health contraindications. Due to additional procedures, it is still safe to donate blood. Efforts to promote blood donation during the COVID-19 pandemic should be continued
