Electron spin dynamics during microwave pulses studied by 94 GHz chirp and phase-modulated EPR experiments
Authors: Lenjer Marvin , Wili Nino , Hecker Fabian , Bennati Marina 
Published: October 2024

Abstract. Electron spin dynamics during microwave irradiation are of increasing interest in electron paramagnetic resonance (EPR) spectroscopy, as locking electron spins into a dressed state finds applications in EPR and dynamic nuclear polarization (DNP) experiments. Here, we show that these dynamics can be probed by modern pulse EPR experiments that use arbitrary waveform generators to produce shaped microwave pulses. We employ phase-modulated pulses to measure Rabi nutations, echoes, and echo decays during spin locking of a BDPA radical at 94 GHz EPR frequency. Depending on the initial state of magnetization, different types of echos are observed. We analyze these distinct coherence transfer pathways and measure the decoherence time T2ρ, which is a factor 3–4 longer than Tm. Furthermore, we use chirped Fourier transform EPR to detect the evolution of magnetization profiles. Our experimental results are well reproduced using a simple density matrix model that accounts for T2ρ relaxation in the spin lock (tilted) frame. The results provide a starting point for optimizing EPR experiments based on hole burning, such as electron-nuclear double resonance or ELDOR-detected NMR.
Influence of water on crystallographic preferred orientation patterns in a naturally deformed quartzite

Published: October 2024

Abstract. Laboratory experiments demonstrate that intragranular water exerts an important control on deformation within quartz, causing weakening and promoting plasticity. The role of water in natural quartz deformation, however, remains unclear, as recent studies find an inverse relationship between water content and the magnitude of plastic strain. Furthermore, little work has investigated the effects, if any, of water on the relative activity of various slip systems in quartz. We focus on a naturally strained quartzite from the Antietam Formation of the Blue Ridge in Virginia, USA. Quartz water content ranges from < 50 to > 2000 ppm H2O. Water content and crystallographic data were correlated for 968 grains, enabling us to explore the relationship between water content and quartz crystallographic preferred orientation (CPO) patterns. “Dry” (< 150 ppm H2O) and “wet” (> 500 ppm H2O) subsets show distinct CPOs; c axes of dry grains define a cross girdle oriented perpendicular to the extension direction (x), whereas c axes of wet grains are concentrated along the perimeter of the pole figure. All water content subsets show grains clustered near the direction of maximum shortening (z), consistent with activity of the basal 〈a〉 slip system. The cross girdle in the driest grains suggests activity of prism 〈a〉 and possibly rhomb 〈a〉, whereas the orientation of the wettest grains implies a contribution from prism [c] slip. These slip system interpretations are supported by analyses of intragranular misorientations. These results indicate that water content impacts the relative activity of various slip systems in natural quartz, potentially affecting application of the quartz opening angle thermometer.

Purpose of the study. analysis of the prevalence of the main risk factors for the development of chronic NCDs in the unorganized population of the Altai Territory aged 25–64 years.Materials and methods. The study involved 1,103 people aged 25–64 years, selected by random sampling from the population of the Altai Territory. The survey was conducted using a standard questionnaire. During the study, the blood pressure level, height, and weight of respondents were measured.Results. The study involved 1103 people, of whom 33.4 % were men (n = 368), women – 66.6 % (n = 735). Smoking was registered in 21.5 % (n = 234), among men – 45.7 % (n = 166), among women – 9.4 % (n = 68). IBP of salt was detected in 58.9 % (n = 650), among men – 63.6 % (n = 234), among women – 56.6 % (n = 416). Consumption of less than 5 servings of fruits and/or vegetables on average per day was noted in 55.7 % (n = 597), among men – 67.6 % (n = 244), among women – 49.6 % (n = 353). NFA occurs in 19.9% (n = 218), among men – 19.4 % (n = 71), women – 20.1 % (n = 47). Obesity occurs in 34.9 (n = 349), among men – 22.3 % (n = 73), women – 41% (n = 276). High blood pressure among all respondents was 50.3 %; in men this risk factor was lower than among women (45.4 % and 52.8 %, respectively).Conclusions. For the first time, the features of the main risk factors for the development of chronic non-diseases were studied in an unorganized sample of the region’s population aged 25–64. Residents of the region have a high incidence of salt IBP, NPOF and elevated blood pressure. The ESSE-RF study made it possible to identify gender and territorial characteristics of our region. Thus, the study demonstrated that both sexes have NPOF and salt IBP, but smoking was more common among men, and high blood pressure among women. This study is the starting point for epidemiological studies in the Altai region and can serve as a guide for further monitoring of the prevalence of risk factors and the effectiveness of preventive programs.

Published: October 2024

Purpose of the study: to determine associations of the prevalence of coronary heart disease and some psychosocial risk factors (negative affective states) among men 25–64 years old in the open population of a mid-urban city in Western Siberia.Material and methods. A cross-sectional study with a response rate of 85.0 % was conducted on a representative sample of men 25–64 years old in the city of Tyumen (n = 1000). To determine the levels of personal anxiety, depression, hostility, vital exhaustion, and sleep quality, the standard WHO MONICA-MOPSY questionnaire was used.Results. In the open population of a mid-urban city in Western Siberia, psychosocial risk factors for CVD are significantly common in men aged 25–64 years: personal anxiety (92.4 %), depression (23.6 %), sleep disturbance (50.9 %), hostility (70.0 %), vital exhaustion (54.5 %). Frequency of detection of high gradations of psychosocial risk factors for CVD – personal anxiety (36.6 %), depression (4.6 %), sleep disorders (9.5 %), hostility (46.4 %), vital exhaustion (15.9 %) – increases with age, reaching a maximum in the sixth decade of life. In men 25–64 years old in a mid-urban city in Western Siberia with the presence of IHD, high levels of PSF are more common than in persons without IHD – personal anxiety (OR 4.07), depression (OR 21.07), sleep disorders (OR 5.05) , hostility (OR 2.71), vital exhaustion (OR 6.02); with the presence of «definite» IHD – significantly more often – personal anxiety (OR 9.51), depression (OR 39.84), sleep disturbance (OR 5.28), hostility (OR 4.65), vital exhaustion (OR 14. eleven).Conclusions. Thus, analysis of the definition of psychosocial risk factors associated with the prevalence of coronary heart disease in men 25–64 years old seems necessary to use when developing a preventive program to reduce high cardiovascular risk in the open population of a mid-urban city in Western Siberia, focused primarily on regulation of psychological parameters.

The purpose of this study was to create a scoring scale for assessing the 10-year risk of cardiovascular events for middle-aged and elderly people with type 2 diabetes mellitus (DM).Material and methods. The analysis included data from 314 people with T2DM: 142 men, 242 women, the average age for both sexes was 60.81 ± 6.38 years. The baseline survey was carried out within the framework of the HAPIEE project; the observation period lasted from 2003–2005. to December 31, 2013 and averaged 10 years. Persons who had myocardial infarction and/or cerebral stroke before the examination were excluded from the analysis. Non-fatal cardiovascular (CV) diseases and CV death were established in accordance with the codes of the International Classification of Diseases, 10th revision. As part of the study, two groups were formed: the main group, which included people with T2DM who “developed CV events” over 10 years of observation – 50 (15.9 %) people, and a comparison group – people with T2DM who “did not develop CV events” during the observation period (264 people). Anthropometric indicators, blood pressure, socio-demographic data, and some biochemical parameters were determined. To analyze the association of the studied factors with the risk of CV events, multivariate stepwise Cox regression analysis was used.Results. As a result of multivariate Cox regression analysis, associations with the risk of developing CV diseases were obtained for the following factors: gender (men), age (≥ 55 years), heart rate (≥ 80 beats/min), SBP (≥ 150 mmHg), marital status single, education (not higher). Individuals with a score above 9 are considered to be at high 10-year risk of cardiovascular events.Conclusions. A model has been created that predicts the risk of developing CV events in relation to individuals with T2DM living in a large industrial city in Western Siberia. Based on the data obtained, it will be possible to select priority preventive areas and therapeutic interventions.

The association between oral cholecalciferol and GFR has been identified in various renal transplant populations around the globe. This study aimed to evaluate the effect of oral cholecalciferol supplementation on the GFR and serum PTH levels, with other parameters in the Saudi kidney transplant population. A retrospective observational study was conducted on a cohort of 174 kidney recipients who underwent transplantation and had serum 25-Hydroxy VD level tests performed (2018-2022) at King Faisal Specialist Hospital and Research Center in Jeddah, KSA. Generalized and linear mixed effects regression models were conducted. The percentage of GFR >60 (25.86% vs 78.16%, P<.0001) and VD insufficiency (< 30 ng/mL) (36.21% vs 6.90%, P<.0001) were significantly different between pre-& post-transplant periods, respectively. After adjustment, significant changes were found in post-transplant GFR, hemoglobin levels, serum creatinine levels, blood urea nitrogen levels, hematocrit levels, PTH levels, and VD 25-Hydroxy from the baseline. Calciferol 1000/2000 IU and 50,000 IU (P<.0001) were significantly more effective in increasing the odds of having GFR >60 as compared to other supplements (P=0.75). VD supplementations may be particularly beneficial in improving kidney function in kidney transplant patients, as this contributes to normalizing GFR levels and creatinine levels and reducing PTH levels.

Makerspaces as complex sociomaterial assemblages
Authors: Koole Marguerite , Anderson Kerry-Anne , Wilson Jay 
Published: October 2024

The emergence of makerspaces is an outgrowth of our current educational and technological era. While making is not new, networking capabilities has made it relatively easy to locate materials, knowledge, procedures, and expertise. Through technologies that are now affordable to consumers, there is a folding of human activity, digital, and material; that is, these practices, previously viewed as separate phenomena or separate regions of activity, blend (Mol & Law, 1994). Physical computing and 3D printing are becoming part of our practice. We can combine electronic, programmable circuitry into traditional crafts such as sewing or origami. Makerspaces are difficult to define because each one is unique, fitting on a continuum of formal to informal and offering different levels of learner/participant control. For example, in some makerspaces facilitators explicitly guide projects; other makerspaces may be gatherings of individuals working on different projects without any discernible leadership. Gatherings may be physical, virtual, or both. The projects, people, and problems may lead to differing degrees of collaboration, sharing and problem solving. We argue that the activities that occur at a given makerspace emerge from the unique characteristics of the space, participants, materials, and networking practices. From a sociomaterial perspective, makerspaces may be viewed as complex assemblages in which the human, digital, and physical are highly entangled. In this paper, we describe a single phase of a larger research project examining the experiences of makerspace facilitators. Our main goal in this phase of the research was to examine the extent to which curating, creating, relating, and networking, as per the makerspace activity (MAP) diagram (Figure 1), are part of the makerspace assemblages described to us by our study participants. For this research, we conducted semi-structured interviews with 13 makerspace facilitators. The participants included teachers, librarians, school technology consultants, and makerspace club members. Our first pass at coding the transcripts resulted in a significant number of codes emerging in the relate category in comparison to the create, curate, and networking categories. This result led us to question the centrality of networking and whether or not relating should be considered the central characteristic of makerspace assemblages. We conclude that networking, while less prevalent in the transcripts (i.e., less salient to our interview participants), remains a significant characteristic. However, we offer a revised version of the MAP diagram in order to recognize the significance of relational learning.
Student Inquiry, Networks of Knowledge and Linked Data
Authors: Carmichael Patrick , Tracy Frances 
Published: October 2024

This paper explores the potential for the development of new learning opportunities in higher education, through students being conceptualised not as consumers, recipients or commodities, but rather as co-researchers and co-producers of knowledge. Specifically, it discusses the implications of new forms of networked knowledge enabled by the emergence of semantic web and linked data technologies and the reconceptualising of the Internet as a ‘global data space’. We draw on our experience of initiating and supporting a range of projects in UK higher education in the course of an extended programme of research and development. Some of these involved the design and development of new technology platforms, while others were focussed on the redevelopment of taught courses, assignments and assessed activities. What these projects had in common is that they all took place in the context of complex learning settings in which some variety of case based learning is used. They involved students drawn from different disciplines in higher education in ‘research-based learning’ about curriculum contexts, and about pedagogical aspects of these contexts. New digital tools were developed in the form of rich web applications that allowed learner interaction with content, in many cases underpinned by data from multiple sources and in diverse formats. In the development of these online technologies, students located, analysed, synthesised and, in some cases, generated new data, and, perhaps more significantly, participated in local or global knowledge networks. What we will argue is that these types of projects involve not only the development of specific techno-literacies, but also that they form the basis of broader ‘critical digital literacies’. These in turn equip students to enter workplaces better positioned to inquire into the particularities of the educational settings in which they work and the practices in which they are engaged. They can thus undertake ‘counter-research’ in which dominant rhetorics are challenged, and evidence bases for policy and practice are subjected to scrutiny, critique and reinterpretation. This presents the potential for students to undertake critical and politicised inquiry as part of a broader reframing of the purposes of higher education.

NEED ASSESSMENT OF TEACHING QUALITATIVE RESEARCH IN UNDERGRADUATE MEDICAL EDUCATION: A MIXED METHOD STUDY
Authors: Adeeb Humera , Qamar Naqvi Syeda Saima , Ullah Ihsan 
Published: October 2024

Background: Accreditation bodies of medical education globally value competency in research that facilitates evidence-based practice of medicine. Physician-scientists need awareness of qualitative research methods for in-depth exploration of sociocultural, gender, behavioural, emotional, and religious factors affecting health that cannot be gauged by quantitative research methods. The introduction of qualitative research at the undergraduate level can enhance understanding of local populations' unique health needs and strengthen evidence-based practice. Methods: This was a mixed-method study conducted from July to October 2021. Four journals with dedicated student’s corner/student journals were hand-searched for qualitative research articles published by students, over the past five years. Quantitative data was collected at four medical colleges of Khyber-Pakhtunkhwa for several qualitative research projects being conducted by students. Quantitative data was collected from the faculty of these colleges about the facilities of research departments. After analysing quantitative data, five semi-structured interviews via email were conducted about factors limiting qualitative research at medical colleges. Written responses were analysed for themes. Results: There was not a single qualitative research article published by students in local journals in five years. Out of 39 research projects by undergraduates at four medical colleges only one was qualitative. Two themes developed from qualitative data were underdeveloped research departments and a lack of attitude toward qualitative research. Conclusion: There is a felt need and gap to include qualitative research objectives at the undergraduate level, but before that emphasis needs to be placed on providing infrastructure, resources, and trained faculty to facilitate implementation. It will facilitate future doctors to find answers to problems impalpable by quantitative methods
