description: Graphene and other two-dimensional materials display remarkable optical properties, including a simple light transparency of $T \approx 1 - πα$ for light in the visible region. Most theoretical rationalizations of this "universal" opacity employ a model coupling light to the electron's crystal momentum and put emphasis on the linear dispersion of the graphene bands. However, such a formulation of interband absorption is not allowable within band structure theory, because it conflates the crystal momentum label with the canonical momentum operator. We show that the physical origin of the optical behavior of graphene can be explained within a straightforward picture with the correct use of canonical momentum coupling. Its essence lies in the two-dimensional character of the density of states rather than in the precise dispersion relation, and therefore the discussion is applicable to other systems such as semiconductor membranes. At higher energies the calculation predicts a peak corresponding to a van Hove singularity as well as a specific asymmetry in the absorption spectrum of graphene, in agreement with previous results.

description: Microstreams are fluctuations in the solar wind speed and density associated with polarity-reversing folds in the magnetic field (also denoted switchbacks). Despite their long heritage, the origin of these microstreams/switchbacks remains poorly understood. For the first time, we investigated periodicities in microstreams during Parker Solar Probe (PSP) Encounter 10 to understand their origin. Our analysis was focused on the inbound corotation interval on 2021 November 19-21, while the spacecraft dove toward a small area within a coronal hole (CH). Solar Dynamics Observatory remote-sensing observations provide rich context for understanding the PSP in-situ data. Extreme ultraviolet images from the Atmospheric Imaging Assembly reveal numerous recurrent jets occurring within the region that was magnetically connected to PSP during intervals that contained microstreams. The periods derived from the fluctuating radial velocities in the microstreams (approximately 3, 5, 10, and 20 minutes) are consistent with the periods measured in the emission intensity of the jetlets at the base of the CH plumes, as well as in larger coronal jets and in the plume fine structures. Helioseismic and Magnetic Imager magnetograms reveal the presence of myriad embedded bipoles, which are known sources of reconnection-driven jets on all scales. Simultaneous enhancements in the PSP proton flux and ionic ($^3$He, $^4$He, Fe, O) composition during the microstreams further support the connection with jetlets and jets. In keeping with prior observational and numerical studies of impulsive coronal activity, we conclude that quasiperiodic jets generated by interchange/breakout reconnection at CH bright points and plume bases are the most likely sources of the microstreams/switchbacks observed in the solar wind.

description: We present a spectroscopic analysis of a sample of 48 M dwarf stars ($0.2 M_{\odot}< M < 0.6 M_{\odot}$) from the Hyades open cluster using high-resolution H-band spectra from the SDSS/APOGEE survey. Our methodology adopts spectrum synthesis with LTE MARCS model atmospheres, along with the APOGEE DR17 line list, to determine effective temperatures, surface gravities, metallicities, and projected rotational velocities. The median metallicity obtained for the Hyades M dwarfs is [M/H]= 0.09$\pm$0.03 dex, indicating a small internal uncertainty and good agreement with optical results for Hyades red-giants. Overall, the median radii are larger than predicted by stellar models by 1.6$\pm$2.3\% and 2.4$\pm$2.3\%, relative to a MIST and DARTMOUTH isochrone, respectively. We emphasize, however, that these isochrones are different and the fractional radius inflation for the fully- and partially-convective regimes have distinct behaviors depending on the isochrone. Using a MIST isochrone there is no evidence of radius inflation for the fully convective stars, while for the partially convective M-dwarfs the radii are inflated by 2.7$\pm$2.1\%, which is in agreement with predictions from models that include magnetic fields. For the partially-convective stars, rapid-rotators present on average higher inflation levels than slow-rotators. The comparison with SPOTS isochrone models indicates that the derived M dwarf radii can be explained by accounting for stellar spots in the photosphere of the stars, with 76\% of the studied M dwarfs having up to 20\% spot coverage, and the most inflated stars with $\sim$20 -- 40\% spot coverage.

description: We report on a timing and spectral analysis of a 50-ks NuSTAR observation of IGR J16320-4751 (= AX J1631.9-4752); a high-mass X-ray binary hosting a slowly-rotating neutron star. In this observation from 2015, the spin period was 1,308.8+/-0.4 s giving a period derivative dP/dt ~ 2E-8 s s-1 when compared with the period measured in 2004. In addition, the pulsed fraction decreased as a function of energy, as opposed to the constant trend that was seen previously. This suggests a change in the accretion geometry of the system during the intervening 11 years. The phase-averaged spectra were fit with the typical model for accreting pulsars: a power law with an exponential cutoff. This left positive residuals at 6.4 keV attributable to the known iron K-alpha line, as well as negative residuals around 14 keV from a candidate cyclotron line detected at a significance of 5-sigma. We found no significant differences in the spectral parameters across the spin period, other than the expected changes in flux and component normalizations. A flare lasting around 5 ks was captured during the first half of the observation where the X-ray emission hardened and the local column density decreased. Finally, the binary orbital period was refined to 8.9912+/-0.0078 d thanks to Swift/BAT monitoring data from 2005-2022.

description: The importance of surface tension effects is being recognized in the context of soft composite solids, where it is found to significantly affect the mechanical properties, such as the elastic response to an external stress. It has recently been discovered that Eshelby's inclusion theory breaks down when the inclusion size approaches the elastocapillary length $L\equivγ/E$, where $γ$ is the inclusion/host surface tension and $E$ is the host Young's modulus. Extending our recent results for liquid inclusions, here we model the elastic behavior of a non-dilute distribution of isotropic elastic spherical inclusions in a soft isotropic elastic matrix, subject to a prescribed infinitesimal far-field loading. Within our framework, the composite stiffness is uniquely determined by the elastocapillary length $L$, the spherical inclusion radius $R$, and the stiffness contrast parameter ${C}$, which is the ratio of the inclusion to the matrix stiffness. We compare the results with those from the case of liquid inclusions, and we derive an analytical expression for elastic cloaking of the composite by the inclusions. Remarkably, we find that the composite stiffness is influenced significantly by surface tension even for inclusions two orders of magnitude more stiff than the host matrix. Finally, we show how to simultaneously determine the surface tension and the inclusion stiffness using two independent constraints provided by global and local measurements.

description: Background In 2003, the Ethiopian Federal Ministry of Health (FMOH) launched a new health care plan, the "Accelerated Expansion of Primary Health Care Coverage," through a comprehensive Health Extension Program (HEP).Recognizing the huge gap between need and health care services available, the FMOH has focused on "providing quality promotive, preventive, and selected curative health care services in an accessible and equitable manner to reach all segments of the population, with special attention to mothers and children (10). Objective To assess on family planning service utilization among model and non model family women enrolled in urban health extension program of kirkos sub-city administration. Method A cross sectional study design using a quantitative method was used .A total of 424 (212 model families and 212 non-model families) participated the study. To establish associations between dependent and independent variables, P values were used. Chi-square test was used to select associated independent variables for multiple logistic regressions. Adjusted ORs that controls the confounding effects of other covariates were calculated using the multiple logistic regression models of SPSS version 16 statistical programs. Statistical significance was considered at Pvalue less than 0.05. Result More in model than non model families (100% versus 93.4% respectively) have heard about cp methods (with p value=0.0002). From those ever use one of contraceptive methods, large proportion study population 210(81.08%) [109(78.4%)) and 101 (84.1%),) model and non model respectively] were they prefer to be informed by health professional and followed by other (like friend husband..) were 27(10.42%) [18(12.9%) and 9(7.5%) for model and non model families respectively] , media (radio and Tv) were 15(5.79%) [5(3.59) and10 (8.33%) for model and non model families respectively] and finally and the lest referred choice of study population were7 (2.7%) [7(5%) and 0 (0) for model and non model families respectively] with X2 =4.21, p value =0.000021. Conclusion the contribution of UHEP on FP utilization can be measured by considering the provision of the program in all aspects of FP service utilization like let the community to inform about the service and then to be as the major preferable informed choice for them. By this measurement the UHEP programs lacks the aspects expected to be done, as we have mentioned earlier. Recommendation FMOH should see the implementation strategies of UHEP on providing and upgrading family planning service

description: Recently, Grabowska and Kaplan proposed a four-dimensional lattice formulation of chiral gauge theories on the basis of a chiral overlap operator. We compute the classical continuum limit of the fermion number anomaly in this formulation. Unexpectedly, we find that the continuum limit contains a term which is not Lorentz invariant. The term is, however, proportional to the gauge anomaly coefficient, and thus the fermion number anomaly in this lattice formulation automatically restores the Lorentz-invariant form when and only when the anomaly cancellation condition is met.

description: Context. Filamentary structures in the interstellar medium are closely related to star formation. Dense gas mass fraction (DGMF) or clump formation efficiency in large-scale filaments possibly determine their hosting star formation activities. Aims. We aim to automatically identify large-scale filaments, characterize them, investigate their association with Galactic structures, and study their DGMFs. Methods. We use a modified minimum spanning tree (MST) algorithm to chain parsec-scale 13CO clumps previously extracted from the SEDIGISM (Structure, Excitation, and Dynamics of the Inner Galactic InterStellar Medium) survey. The MST connects nodes in a graph such that the sum of edge lengths is minimum. Modified MST also ensures velocity coherence between nodes, so the identified filaments are coherent in position-position-velocity (PPV) space. Results. We generate a catalog of 88 large-scale ($>10pc$) filaments in the inner Galactic plane (with $-60^\circ < l < 18^\circ and $|b| < 0.5^\circ$). These SEDIGISM filaments are larger and less dense than MST filaments previously identified from the BGPS and ATLASGAL surveys. We find that eight of the filaments run along spiral arms and can be regarded as "bones" of the Milky Way. We also find three bones associated with the Local Spur in PPV space. By compiling 168 large-scale filaments with available DGMF across the Galaxy, an order of magnitude more than previously investigated, we find that DGMFs do not correlate with Galactic location, but bones have higher DGMFs than other filaments.

description: Tourism in Greece occupying 20.8% of GDP is part of the "heavy industry" of Greece. Mass tourism, which has been developed since the 1950s, has brought about not only economic growth but also negative effects on both the natural and cultural environment. Understanding these impacts, the international communities have raised the issue of sustainability. The need for development that benefits both the present and the future. Sustainable tourism development with outlets for soft forms of tourism is an urgent need. Protected areas are of interest and how they can contribute to the development of the regions without harming the environment. In this thesis, the legislation and status of natural protected areas are analyzed and an attempt is made to analyze the tourism product of the Rhodope Mountains National Park. The aim of the thesis is to find the advantages and disadvantages of the tourism product of the region and how it can be improved and become part of the Sustainable Development of the wider area of the Rhodope National Park.

description: In this work, we have studied the possibility of setting up Bell's inequality violating experiment in the context of cosmology, based on the basic principles of quantum mechanics. First we start with the physical motivation of implementing the Bell's inequality violation in the context of cosmology. Then to set up the cosmological Bell violating test experiment we introduce a model independent theoretical framework using which we have studied the creation of new massive particles by implementing the WKB approximation method for the scalar fluctuations in presence of additional time dependent mass contribution. Next using the background scalar fluctuation in presence of new time dependent mass contribution, we explicitly compute the expression for the one point and two point correlation functions. Furthermore, using the results for one point function we introduce a new theoretical cosmological parameter which can be expressed in terms of the other known inflationary observables and can also be treated as a future theoretical probe to break the degeneracy amongst various models of inflation. Additionally, we also fix the scale of inflation in a model independent way without any prior knowledge of primordial gravitational waves. Next, we also comment on the technicalities of measurements from isospin breaking interactions and the future prospects of newly introduced massive particles in cosmological Bell violating test experiment. Further, we cite a precise example of this set up applicable in the context of string theory motivated axion monodromy model. Then we comment on the explicit role of decoherence effect and high spin on cosmological Bell violating test experiment. In fine, we provide a theoretical bound on the heavy particle mass parameter for scalar fields, graviton and other high spin fields from our proposed setup.

description: We present the first X-ray observation at sub-arcsecond resolution of the high-redshift ($z=6.18$) radio-loud quasar CFHQS J142952+544717 (J1429). The ~100 net-count 0.3-7 keV spectrum obtained from $\sim 30$ ksec Chandra exposure is best fit by a single power-law model with a photon index $Γ=2.0\pm0.2$ and no indication of an intrinsic absorber, implying a 3.6-72 keV rest-frame luminosity $L_{\rm X}=(2.3^{+0.6}_{-0.5})\times10^{46}$ erg s$^{-1}$. We identify a second X-ray source at 30 arcsec, distance from J1429 position, with a soft ($Γ\simeq 2.8$) and absorbed (equivalent hydrogen column density $N_{\rm H} <13.4\times 10^{20}$ cm$^{-2}$) spectrum, which likely contaminated J1429 spectra obtained in lower angular resolution observations. Based on the analysis of the Chandra image, the bulk of the X-ray luminosity is produced within the central $\sim 3$ kpc region, either by the disk/corona system, or by a moderately aligned jet. In this context, we discuss the source properties in comparison with samples of low- and high-redshift quasars. We find indication of a possible excess of counts over the expectations for a point-like source in a 0.5 arcsec-1.5 arcsec ($\sim 3-8$ kpc) annular region. The corresponding X-ray luminosity at J1429 redshift is $4\times 10^{45}$ erg s$^{-1}$. If confirmed, this emission could be related to either a large-scale X-ray jet, or a separate X-ray source.

description: Objective: To investigate the use of 5α-reductase inhibitors (5ARIs) and α-blockers among men with benign prostatic hyperplasia (BPH) in relation to prostate cancer (PCa) incidence, severity and mortality. Patients and Methods: A retrospective 20-year cohort study in men residing in Saskatchewan, aged 40–89 years, with a BPH-coded medical claim between 1995 and 2014, was conducted. Cox proportional hazards regression was used to compare incidence of PCa diagnosis, metastatic PCa, Gleason score 8–10 PCa, and PCa mortality among 5ARI users (n = 4 571), α-blocker users (n = 7 764) and non-users (n = 11 677). Results: In comparison with both non-users and α-blocker users, 5ARI users had a ~40% lower risk of a PCa diagnosis (11.0% and 11.4% vs 5.8%, respectively), and α-blocker users had an 11% lower risk of a PCa diagnosis compared with non-users. Overall, the incidence of metastatic PCa and PCa mortality was not significantly different among 5ARI or α-blocker users compared with non-users (adjusted hazard ratios [HR] of metastatic PCa: 1.12 and 1.13, respectively, and PCa mortality: 1.11 and 1.18, respectively, P > 0.05 for both drugs), but both 5ARI and a-blocker users had ~30% higher risk of Gleason score 8–10 cancer, adjusted HR 1.37, 95% confidence interval [CI] 1.03–1.82, P = 0.03, and adjusted HR 1.28, 95% CI 1.03–1.59, P = 0.02, respectively compared with non-users. Conclusion: The use of 5ARIs was associated with lower risk of PCa diagnosis, regardless of comparison group. Risk of high grade PCa was higher among both 5ARI users and α-blocker users compared with non-users; however, this did not translate into higher risk of PCa mortality.

Παράλληλα, η χρήση συστημάτων κυκλικής κίνησης τα οποία περιλαμβάνουν μεγαλύτερο αριθμό μικροεργαλείων σε σύγκριση με αυτά της παλίνδρομης, θεωρούνται εξίσου επιβαρυντικά για τους οδοντικούς ιστούς. Σκοπός της παρούσας μελέτης είναι να εξεταστεί η επίδραση της κίνησης των μικροεργαλείων προπαρασκευής στην αντοχή θραύσης ενδοδοντικά θεραπευμένων δοντιών.
description: The aim of this study was to compare the use of two Ni-Ti instrument systems with different kinematics on their influence on the fracture resistance of endodontically treated roots under in vitro experimental conditions. The last decades, a numerous range of nickel-titanium instruments have been introduced in the market, promising decreased working time and improved clinical results. Motion of the Ni-Ti system is a parameter separating them to rotary and reciprocating files. There have been a number of studies investigating the effects of the NiTi instruments on dentine and the possibility of causing vertical root fractures. However, to the best of our knowledge, none of them has tried to elucidate the effect of motion of the NiTi-file system on the VRF development. Thus, the purpose of this investigation was to examine the influence of instrument motion on the fracture resistance of endodontically treated roots after preparation with rotary (ProTaper Gold), reciprocating (WaveOne Gold) and hand files.

description: It is generally expected that heavy fields are present during inflation, which can leave their imprint in late-time cosmological observables. The main signature of these fields is a small amount of distinctly shaped non-Gaussianity, which if detected, would provide a wealth of information about the particle spectrum of the inflationary Universe. Here we investigate to what extent these signatures can be detected or constrained using futuristic 21-cm surveys. We construct model-independent templates that extract the squeezed-limit behavior of the bispectrum, and examine their overlap with standard inflationary shapes and secondary non-Gaussianities. We then use these templates to forecast detection thresholds for different masses and couplings using a 3D reconstruction of modes during the dark ages ($z\sim 30-100$). We consider interactions of several broad classes of models and quantify their detectability as a function of the baseline of a dark ages interferometer. Our analysis shows that there exists the tantalizing possibility of discovering new particles with different masses and interactions with future 21-cm surveys.

description: Hot DA white dwarfs have fully radiative pure hydrogen atmospheres that are the least complicated to model. Pulsationally stable, they are fully characterized by their effective temperature Teff, and surface gravity log g, which can be deduced from their optical spectra and used in model atmospheres to predict their spectral energy distribution (SED). Based on this, three bright DAWDs have defined the spectrophotometric flux scale of the CALSPEC system of HST. In this paper we add 32 new fainter (16.5 < V < 19.5) DAWDs spread over the whole sky and within the dynamic range of large telescopes. Using ground based spectra and panchromatic photometry with HST/WFC3, a new hierarchical analysis process demonstrates consistency between model and observed fluxes above the terrestrial atmosphere to < 0.004 mag rms from 2700 Å to 7750 Å and to 0.008 mag rms at 1.6μm for the total set of 35 DAWDs. These DAWDs are thus established as spectrophotometric standards with unprecedented accuracy from the near ultraviolet to the near-infrared, suitable for both ground and space based observatories. They are embedded in existing surveys like SDSS, PanSTARRS and GAIA, and will be naturally included in the LSST survey by Rubin Observatory. With additional data and analysis to extend the validity of their SEDs further into the IR, these spectrophotometric standard stars could be used for JWST, as well as for the Roman and Euclid observatories.

description: Aim: To provide a detailed genomic-epidemiological description of a complex multi-ward SARS-CoV-2 outbreak, which originated in the crowded emergency department (ED) in our hospital during the third wave of the COVID-19 pandemic, and was elucidated promptly by local whole-genome sequencing (WGS).Methods: SARS-CoV-2 was detected by reverse transcriptase real-time polymerase chain reaction on viral RNA extracted from nasopharyngeal swabs. WGS was performed using an Oxford MinION Mk1C instrument following the ARTIC v3 sequencing protocol. High-quality consensus genomes were assembled with the artic-ncov2019 bioinformatics pipeline and viral phylogenetic trees were built, inferred by maximum-likelihood. Clusters were defined using a threshold of 0e1 single nucleotide polymorphisms (SNPs) between epidemiologically linked sequences.Results: In April 2021, outbreaks of COVID-19 were declared on two wards at University Hospital Limerick after 4 healthcare-associated SARS-CoV-2 infections were detected by post-admission surveillance testing. Contact tracing identified 12 further connected cases; all with direct or indirect links to the ED ‘COVID Zone’. All sequences were assigned to the Pangolin B.1.1.7 lineage by WGS, and SNP-level analysis revealed two distinct but simul?taneous clusters of infections. Repeated transmission in the ED was demonstrated, involving patients accommodated on trolleys in crowded areas, resulting in multiple generations of infections across three inpatient hospital wards and subsequently to the local community. These findings informed mitigation efforts to prevent cross-transmission in the ED.Conclusion: Cross-transmission of SARS-CoV-2 occurred repeatedly in an overcrowded emergency department. Viral WGS elucidated complex viral transmission networks in our hospital and informed infection, prevention and control practice.

description: We report resonant elastic X-ray scattering (REXS) of long-range magnetic order in EuPtSi$_{\text{3}}$, combining different scattering geometries with full linear polarization analysis to unambiguously identify magnetic scattering contributions. At low temperatures, EuPtSi$_{\text{3}}$ stabilizes type A antiferromagnetism featuring various long-wavelength modulations. For magnetic fields applied in the hard magnetic basal plane, well-defined regimes of cycloidal, conical, and fan-like superstructures may be distinguished that encompass a pocket of commensurate type A order without superstructure. For magnetic field applied along the easy axis, the phase diagram comprises the cycloidal and conical superstructures only. Highlighting the power of polarized REXS, our results reveal a combination of magnetic phases that suggest a highly unusual competition between antiferromagnetic exchange interactions with Dzyaloshinsky--Moriya spin--orbit coupling of similar strength.

description: In this paper, we present new analytical solutions of the Bohr Hamiltonian problem that we derived with the Tietz-Hua potential, here used for describing the β-part of the nuclear collective potential plus harmonic oscillator one for the γ-part. Also, we proceed to a systematic comparison of the numerical results obtained with this kind of β-potential with others which are widely used in such a framework as well as with the experiment. The calculations are carried out for energy spectra and electromagnetic transition probabilities for γ-unstable and axially symmetric deformed nuclei. In the same frame, we show the effect of the shape flatness of the β-potential beyond its minimum on transition rates calculations.

Disrespect and abuse during facility-based child birth in Yeka Sub-City health centers Addis Abeba, Ethiopia.
Creators: name: Gebreamanuel, Teshome

description: Background: In Ethiopia, only 48% of all births occur at health facilities. Disrespect and abuse of women by health providers during child birth is one of the main reasons that affect health care seeking from health facilities. Providing compassionate and respectful maternity care services to laboring and delivering women is one of the most important interventions to ensure positive newborn and maternal outcome. However, compassionate and respectful maternity care has received less attention both in practice and research. Objective: To assess the magnitude of disrespect and abuse faced by women during facility based child birth in Yeka Sub- City selected health centers, Addis Ababa, Ethiopia. Method: Institution based cross-sectional study design was employed among five health centers in Yeka Sub-City health centers, Addis Ababa, Ethiopia. Systematic sampling method was used to include 333 women who had given birth at health centers between February 14 and April 9, 2019. Data were collected using a structured face-to-face interview questionnaire. The data were analyzed by Statistical Package for Social Science (SPSS) Versions 22. Descriptive statistics like frequency, percentage, means and standard deviation were used to summarize the data. Bi-variable and multivariable analysis was performed using logistic regression model to identify factors for disrespect and abuse during childbirth. Result: A total of 319 women participated in the study; with a response rate of 95.8%. From the total respondents, 85.3% of women experienced at least one category of disrespect and abuse. The most prevalent forms of disrespect and abuse were ineffective communication 235 (73.7%) and unacceptable companionship 220 (69%) during labor and delivery. Disrespect and abuse were more prevalent during night shifts deliveries (adjusted odds ratio [AOR] = 4.42; 95% CI, 1.91 to10.23), on women who normalized disrespect and abuse (AOR = 2.20; 95% CI, 1.10 to 4.56) and on mothers who delivered by female attendants (AOR = 3.95; 95% CI, 1.10 to 14.64). Disrespect & Abuse during childbirth in Yeka Sub- City, Ethiopia viii Conclusion and recommendation: The occurrence of disrespect and abuse was high in this study setting. To decrease the existence of this phenomenon, appropriate interventions should be designed, focusing on supervision during night shifts, empowering women of childbearing age about their rights at health facilities and providing training for health care providers about respectful maternity care. Further community based research incorporated with qualitative method will be needed to explore the possible reasons for disrespect and abuse during facility-based childbirth.

description: Determining the mechanism responsible for the plasma heating and particle acceleration is a fundamental problem in the study of the heliosphere. Due to efficient wave-particle interactions of ion-scale waves with charged particles, these waves are widely believed to be a major contributor to ion energization, and their contribution considerably depends on the wave occurrence rate. By analyzing the radial distribution of quasi-monochromatic ion-scale waves observed by the Parker Solar Probe, this work shows that the wave occurrence rate is significantly enhanced in the near-Sun solar wind, specifically 21%$-$29% below 0.3 au, in comparison to 6%$-$14% beyond 0.3 au. The radial decrease of the wave occurrence rate is not only induced by the sampling effect of a single spacecraft detection, but also by the physics relating to the wave excitation, such as the enhanced ion beam instability in the near-Sun solar wind. This work also shows that the wave normal angle $θ$, the absolute value of ellipticity $ε$, the wave frequency $f$ normalized by the proton cyclotron frequency $f_{\mathrm{cp}}$, and the wave amplitude $δB$ normalized by the local background magnetic field $B_0$ slightly vary with the radial distance. The median values of $θ$, $|ε|$, $f$, and $δB$ are about $9^\circ$, $0.73$, $3f_{\mathrm{cp}}$, and $0.01B_0$, respectively. Furthermore, this study proposes that the wave mode nature of the observed left-handed and right-handed polarized waves corresponds to the Alfvén ion cyclotron mode wave and the fast-magnetosonic whistler mode wave, respectively.

description: The present thesis aims to highlight the interpreting profession through the recording of personal experiences narrated by professional interpreters in the context of interviews and is oriented towards the didactics of interpreting. Based on a sociological approach of interpreting, the main objective of the interviews was to understand the process behind the outcome of interpreting, to explore the importance of teaching interpreting and to acknowledge the role of interpreters, who, even today, are characterized by obscurity. Therefore, it was deemed essential to focus on the path of the participating interpreters towards choosing the profession of interpreting as well as their subsequent development in the field.

Με γνώμονα την κοινωνιολογική προσέγγιση της διερμηνείας, βασικός στόχος των συνεντεύξεων ήταν να γίνει αντιληπτή η διαδικασία που κρύβεται πίσω από το αποτέλεσμα της διερμηνείας, να διερευνηθεί η σημασία της διδακτικής της και να αναγνωριστεί ο ρόλος των διερμηνέων, οι οποίοι, ακόμη και σήμερα, χαρακτηρίζονται από αφάνεια. Ως εκ τούτου, κρίθηκε απαραίτητο να τεθεί στο επίκεντρο της μελέτης η πορεία των συμμετεχουσών διερμηνέων προς την επιλογή άσκησης του επαγγέλματος, αλλά και η μετέπειτα εξέλιξή τους στο χώρο.
