Authors: Işıtan Kılıç Damla , Aykut Çığıl
Published: April 2024

Çocukların okul öncesi dönemde kazanmaları gereken erken okuryazarlık becerileri formal okuryazarlık öncesinde ön koşul bilgi, beceri ve tutumları ifade etmektedir. Okul öncesi dönemde doğal olarak gerçekleşen bazı öğrenme fırsatları çocukların erken okuryazarlık becerilerini kazanmalarında önemli bir rol oynamaktadır. Görme becerilerinde sınırlılık yaşayan çocuklar için ise doğal öğrenme fırsatları yetersiz kalabilmektedir. Bu durum gören akranlarıyla karşılaştırıldıklarında görme yetersizliğinden etkilenmiş çocukların erken okuryazarlık becerileriyle bağlantılı alanlarda yeterince gelişim sağlayamamalarına neden olmaktadır. Alanyazında tüm çocukların erken okuryazarlık becerilerinin erken dönemlerden itibaren desteklenmesi gerektiği ifade edilmektedir. Bu destek çocukların bireysel ihtiyaçları ve becerileri göz önünde bulundurularak farklılaştırılmalıdır. Görme yetersizliği olan çocukların erken okuryazarlık becerilerinin desteklenmesinde görme sınırlılığından etkilenme düzeylerine göre farklı uyarlamalar gerekebilmektedir. Bu kapsamda bu çalışmada alanyazında yapılan araştırmaların derlenmesiyle erken okuryazarlık, erken okuryazarlık becerileri ve görme yetersizliğinin erken okuryazarlık becerilerine etkisi farklı etmenler açısından ele alınmıştır. Ayrıca çalışmada görme yetersizliğinden etkilenmiş çocukların erken okuryazarlık becerilerinin desteklenmesine yönelik çeşitli önerilere yer verilmiştir.

Karikatur als Kunstgenre und Darstellungstechnik: E.T.A. Hoffmanns zeichnerische und literarische Karikaturen
Authors: Vordermayer Laura
Published: April 2024

Abstract August Wilhelm Schlegel beschreibt die Karikatur in seiner Kunstlehre (1884) als ,,Spiel“, in dem sich die ,,Unbändigkeit der Phantasie […] Luft macht“.1 Die zentrale Dynamik der Karikatur besteht in einem Zusammenspiel von
Wiedererkennbarkeit und Fiktionalität, das E.T.A. Hoffmann auf vielfältige Weise fruchtbar macht und das sich je nach Medium unterschiedlich gestaltet. In meinem Beitrag untersuche ich sowohl zeichnerische als auch literarische Karikaturen, wobei ich im Besonderen auf die Texte Das
steinerne Herz (1817) und Die Brautwahl (1819) eingehe. In der medienübergreifenden Analyse wird deutlich, welches Potential ein geschärfter Karikaturbegriff auch für die Textinterpretation haben kann.
Hoffmann’s Signature Doodles
Authors: Dickson Polly
Published: April 2024

Abstract As scholars familiar with his manuscripts and drawings will know, E.T.A. Hoffmann had the idiosyncratic and rather charming habit of signing off some of his informal letters not with a signature in the conventional sense, but with a spontaneous self-portrait: a doodle.
The aim of this article is to examine such forms by framing them within the context of a broader question about Hoffmann’s doodles and drawings. Specifically, it places his ‘signature doodles’ at the centre of a graphic conversation between the contingencies of the medium
and an impulse towards meaningful form. It is in that sense that they open up a space for new reflections on the author’s relationship to writing and drawing, registering a vision of the author not as an authorizing or authoritative entity, held above and separate from the work, but
rather as a peculiar entanglement of self and work, whose identity is defined and confirmed from within the act of composition.
Development of test methods for fire-retardant coatings of steel engineering structures during operation
Authors: Komarova M. A. , Grishin I. A. , Shalabin M. V. , Melnikov N. O.
Published: April 2024

Introduction. Prediction of the durability of flame-retardant coatings of steel engineering structures and preservation of their performance during operation remain important research directions. There is a lack of normative documents in the field of fire protection, regulating the process of testing of flame-retardant coatings during operation, as well as determination of their durability (service life).

Aim. To develop test methods for determining the resistance of flame-retardant coatings of steel engineering structures exposed to climatic factors, preservation of their fireproof and anti-corrosion properties during operation.

Materials and methods. Test specimens included 600 x 600 x 5 mm plates made of 08kp and 08ps sheet steel according to State Standard 16523-97 and State Standard 9045-93 with a flame-retardant agent applied on the front side.

Results. Methods for testing thin-layer intumescent and structural flame-retardant coatings during operation are proposed. The methodology of accelerated climatic testing of specimens coated with thin-layer intumescent flame-retardant coatings (flame-retardant paints) corresponds to State Standard 9.401-2018. These coatings are inherently high-solid paint materials. A new methodology, sequence, and modes of testing are developed for structural flame-retardant coatings. The subsequent assessment of fireproof properties of coatings and their preservation is carried out by the methods of fire protection efficiency according to State Standard R 53295-99 and the methods of thermal analysis. These methods imply comparison of the characteristics of the initial flame-retardant coating and those obtained after sample aging. The preservation of fireproof properties by thin-layer intumescent and structural coatings is additionally evaluated by the intumescence coefficient and the change in thermal conductivity, respectively.

Conclusions. Test methods for flame-retardant coatings of steel engineering structures during operation are developed. Threshold levels of changes in their properties are established. After accelerated climatic tests, fire protection efficiency should not decrease by no more than 20 %. For structural fire protection, an increase in thermal conductivity by no more than 5 % is permitted. For thin-layer coatings, the arithmetic mean value of the intumescence coefficient should not decrease by no more than 30 % of the initial value.

Implications. The developed methods were used in the preparation of a draft national standard of the Russian Federation “Steel engineering structures with fireproof coatings. Test methods for anticorrosion properties and resistance to climatic factors during operation” to ensure regulatory fire safety requirements for these structures.
Justification of measures aimed at ensuring the required fire resistance of structures enclosing NPP premises using CFD fire modeling

Published: April 2024

Introduction. The article presents a methodological approach to justifying measures designed to ensure the required fire resistance of structures enclosing NPP premises with the use of CFD (computational fluid dynamics) fire modeling. Approaches to justifying fire safety are considered using the fuel storage facility of an NPP standby diesel power plant as an example.

Aim. To develop and analyze the methodological approach to justifying measures designed to ensure the required fire resistance of structures enclosing NPP premises with the use of CFD fire modeling.

Materials and methods. The purpose and application scope of various methods for modeling fire dynamics was analyzed. Fire modeling used to justify measures for ensuring the required fire resistance of enclosing structures was considered using the fuel storage facility of an NPP standby diesel power plant as an example.

Results. The performed analysis of different methods for modeling fire dynamics shows the possibility of using different fire simulation methods in the analysis of the fire hazard of buildings and facilities. The most dangerous fire development scenarios were modeled and the obtained results were analyzed on the example of a specific typical NPP facility in the NPP emergency power supply system. The redundancy requirements for these systems were taken into account to ensure tolerance to system failures in case of process failures and external effects on these systems.

Conclusion. Since the CFD method is the most universal of the existing deterministic methods, it can be widely used to determine/revise the requirements for fire resistance of load-bearing and enclosing structures at NPP premises. It is possible to apply CFD-based fire modeling for the fire hazard of various buildings and facilities. This model is particularly effective in justifying the sufficiency of fire resistance requirements established for structures to prevent the spread of fire beyond the fire zone within the estimated burnout time of the entire fire load The obtained regularities can be used in the development/revision of regulatory documents on fire safety at operating NPPs and NPPs under construction.

Authors: SC Nwaokocha , CG Gekpe , OE. Ofem , Chidiebere Ezeani
Published: April 2024

Exposure to environmental toxins like Lead has been associated with male infertility. Whether or not potent antioxidants like omega 3 Fatty acids and/or quercetin could reduce the effect of lead on male sexual functions deserve scientific investigation. Thirty-five (35) male albino Wistar rats were assigned into 7 groups: Group 1 (normal control), Group 2 (sham-control1), Group 3 (sham-control 2), Group 4 (Lead group), Group 5 (Lead + Omega-3), Group 6 (Lead + Quercetin) and Group 7 (Lead + Omega-3 + Quercetin). Lead was given orally at 20mg/kg bwt, quercetin 20mg/kg bwt s.c, Omega-3 14.29mg/kg bwt orally. The animals all had free access to rat food and water for 56 days. After which they were sacrificed, and semen and blood samples were collected for assay. The results showed no significant difference between normal control group and sham controls. Sperm function parameters (sperm count, motile, viable and normal sperms) in the lead treated group was significantly reduced compared to the control. Omega 3 and/or quercetin administration reversed the reductions in sperm function parameters to near control levels. Hormone levels (LH and Testosterone) were significantly reduced in lead group compared to the normal control but were reversed after quercetin and omega 3 treatment. However, there was no significant difference in the FSH level among experimental groups. Conclusively, omega 3 and/or quercetin ameliorates the harmful effects of lead on reproductive parameters by improving sperm functions (total sperm count, viability, motility, and morphology). A combination of both quercetin and omega 3 provided better ameliorative effect than either omega 3 or quercetin.

Authors: D. Gonkpala Friendship , S. Flomo, Jr. Mogana
Published: April 2024

Burnout among healthcare workers is a significant concern globally, particularly in low-resource settings like Liberia. This mixed-methods study aimed to assess burnout levels and identify contributing factors among healthcare workers at C.B. Dunbar Hospital and The Baptist Clinic in Gbarnga City, Bong County, Liberia. Quantitative data on burnout levels and work- life balance perceptions were collected from 50 healthcare workers, supplemented by qualitative insights from interviews. Findings revealed that a majority of participants experienced frequent workload-related stress, highlighting the pervasive nature of burnout in this context. Despite challenges, many healthcare workers reported moderate to positive work-life balance perceptions. Logistic regression analysis identified workload and work-life balance perceptions as significant predictors of burnout. Qualitative analysis further elucidated the complex interplay of factors contributing to burnout, including workload pressures, inadequate support systems, and stigma surrounding mental health issues. The study underscores the importance of implementing targeted interventions to mitigate burnout among healthcare workers in Liberia, including improving workload management, enhancing support systems, and promoting a culture of work-life balance.
Post-Treatment Effects of Multiple Sclerosis (MS) on the Executive and Memory Functions ofCommercial Pilots in the UAE
Authors: Muhammed Nawaz Saima , Nawaz Nuzhat
Published: April 2024

Individuals with MS often face challenges in cognitive functioning, particularly in demanding occupations such as commercial flying. This study investigates the post-treatment impact of MS on the memory and executive functions of commercial pilots while working under a busy flying roster. The research aims to understand cognitive changes over time and their implications for onboard safety.Data was collected over two and a half years from a single pilot. Standard assessments were used to evaluate the pilot’s executive and memory functions. A two-way ANOVA table was used for statisticalanalysis. The analysis indicates that there is no significant decline in performance over time for the pilot (p = 0.106447, df = 3). However, there are notable variations among memory and executive function tasks (p < 0.001, df = 7), highlighting specific areas of strength. The null hypothesis there is no decline in pilots’ neurocognitive functions, has been accepted. Additionally, the case study outcomes showed improvement in the pilot's executive and memory functions over two and a half years while maintaining stressful long-haul flight rosters. Future research should focus on understanding the factors driving these variations and exploring interventions to address cognitive weaknesses.

Within the first few hundreds of millions of years, many physical processes sculpt the eventual properties of young planets. NASA’s Transiting Exoplanet Survey Satellite (TESS) mission has surveyed young stellar associations across the entire sky for transiting planets, providing glimpses into the various stages of planetary evolution. Using our own detection pipeline, we search a magnitude-limited sample of 7219 young stars (≲200 Myr) observed in the first 4 yr of TESS for small (2–8 R
⊕), short period (1.6–20 days) transiting planets. The completeness of our survey is characterized by a series of injection and recovery simulations. Our analysis of TESS 2 minute cadence and Full Frame Image (FFI) light curves recover all known TESS Objects of Interest (TOIs), as well as four new planet candidates not previously identified as TOIs. We derive an occurrence rate of

We consistently find a mild increase in the occurrence of super-Neptunes and a significant increase in the occurrence of Neptune-sized planets with orbital periods of 6.2–12 days when compared to their mature counterparts. The young planet distribution from our study is most consistent with evolution models describing the early contraction of hydrogen-dominated atmospheres undergoing atmospheric escape and inconsistent with heavier atmosphere models offering only mild radial contraction early on.

We report the discovery of 15 exceptionally luminous 10 ≲ z ≲ 14 candidate galaxies discovered in the first 0.28 deg2 of JWST/NIRCam imaging from the COSMOS-Web survey. These sources span rest-frame UV magnitudes of −20.5 > M
UV > −22, and thus constitute the most intrinsically luminous z ≳ 10 candidates identified by JWST to date. Selected via NIRCam imaging, deep ground-based observations corroborate their detection and help significantly constrain their photometric redshifts. We analyze their spectral energy distributions using multiple open-source codes and evaluate the probability of low-redshift solutions; we conclude that 12/15 (80%) are likely genuine z ≳ 10 sources and 3/15 (20%) likely low-redshift contaminants. Three of our z ∼ 12 candidates push the limits of early stellar mass assembly: they have estimated stellar masses ∼ 5 × 109

At such high redshifts, the duty cycle for starbursts would be of order unity, which could cause the observed change in the shape of the UV luminosity function from a double power law to a Schechter function at z ≈ 8. Spectroscopic redshift confirmation and ensuing constraints of their masses will be critical to understand how, and if, such early massive galaxies push the limits of galaxy formation in the Lambda cold dark matter paradigm.

Sub/millimeter galaxies are a key population for the study of galaxy evolution because the majority of star formation at high redshifts occurred in galaxies deeply embedded in dust. To search for this population, we have performed an extensive survey with Atacama Large Millimeter/submillimeter Array (ALMA), called the ALMA Lensing Cluster Survey (ALCS). This survey covers 133 arcmin2 area and securely detects 180 sources at z ∼ 0.5–6 with a flux limit of ∼0.2 mJy at 1.2 mm. Here, we report the results of multiwavelength spectral energy distribution analysis of the whole ALCS sample, utilizing the observed-frame UV to millimeter photometry. We find that the majority of the ALCS sources lie on the star-forming main sequence, with a smaller fraction showing intense starburst activities. The ALCS sample contains high infrared-excess sources (

), including two extremely dust-obscured galaxies (IRX > 5). We also confirm that the ALCS sample probes a broader range in lower dust mass than conventional submillimeter galaxy samples in the same redshift range. We identify six heavily obscured active galactic nucleus (AGN) candidates that are not detected in the archival Chandra data in addition to the three X-ray AGNs reported by Uematsu et al. (2023). The inferred AGN luminosity density shows a possible excess at z = 2–3 compared with that determined from X-ray surveys below 10 keV.

Solar radio U-bursts are generated by electron beams traveling along closed magnetic loops in the solar corona. Low-frequency (<100 MHz) U-bursts serve as powerful diagnostic tools for studying large-sized coronal loops that extend into the middle corona. However, the positive frequency drift component (descending leg) of U-bursts has received less attention in previous studies, as the descending radio flux is weak. In this study, we utilized LOFAR interferometric solar imaging data from a U-burst that has a significant descending leg component, observed between 10 and 90 MHz on 2020 June 5th. By analyzing the radio source centroid positions, we determined the beam velocities and physical parameters of a large coronal magnetic loop that reached just about 1.3 R
⊙ in altitude. At this altitude, we found the plasma temperature to be around 1.1 MK, the plasma pressure around 0.20 mdyn, cm−2, and the minimum magnetic field strength around 0.07 G. The similarity in physical properties determined from the image suggests a symmetric loop. The average electron beam velocity on the ascending leg was found to be 0.21c, while it was 0.14c on the descending leg. This apparent deceleration is attributed to a decrease in the range of electron energies that resonate with Langmuir waves, likely due to the positive background plasma density gradient along the downward loop leg.
Multiphase Gas in Elliptical Galaxies: The Role of Type Ia Supernovae
Authors: Mohapatra Rajsekhar , Quataert Eliot
Published: April 2024

Massive elliptical galaxies harbor large amounts of hot gas (T ≳ 106 K) in their interstellar medium (ISM) but are typically quiescent in star formation. The jets of active galactic nuclei (AGNs) and Type Ia supernovae (SNe Ia) inject energy into the ISM, which offsets its radiative losses and keeps it hot. SNe Ia deposit their energy locally within the galaxy compared to the larger few ×10 kiloparsec-scale AGN jets. In this study, we perform high-resolution (5123) hydrodynamic simulations of a local (1 kpc3) density-stratified patch of the ISM of massive galaxies. We include radiative cooling and shell-averaged volume heating, as well as randomly exploding SN Ia. We study the effect of different fractions of supernova (SN) heating (with respect to the net cooling rate), different initial ISM density/entropy (which controls the growth time t
ti of the thermal instability), and different degrees of stratification (which affect the freefall time t
ff). We find that SNe Ia drive predominantly compressive turbulence in the ISM with a velocity dispersion of σ

, in agreement with theoretical expectations that large density fluctuations efficiently trigger multiphase gas formation. Since the SN Ia rate is not self-adjusting, when the net cooling drops below the net heating rate, SNe Ia drive a hot wind which sweeps out most of the mass in our local model. Global simulations are required to assess the ultimate fate of this gas.

Quasars are bright and unobscured active galactic nuclei (AGN) thought to be powered by the accretion of matter around supermassive black holes at the centers of galaxies. The temporal variability of a quasar’s brightness contains valuable information about its physical properties. The UV/optical variability is thought to be a stochastic process, often represented as a damped random walk described by a stochastic differential equation (SDE). Upcoming wide-field telescopes such as the Rubin Observatory Legacy Survey of Space and Time (LSST) are expected to observe tens of millions of AGN in multiple filters over a ten year period, so there is a need for efficient and automated modeling techniques that can handle the large volume of data. Latent SDEs are machine learning models well suited for modeling quasar variability, as they can explicitly capture the underlying stochastic dynamics. In this work, we adapt latent SDEs to jointly reconstruct multivariate quasar light curves and infer their physical properties such as the black hole mass, inclination angle, and temperature slope. Our model is trained on realistic simulations of LSST ten year quasar light curves, and we demonstrate its ability to reconstruct quasar light curves even in the presence of long seasonal gaps and irregular sampling across different bands, outperforming a multioutput Gaussian process regression baseline. Our method has the potential to provide a deeper understanding of the physical properties of quasars and is applicable to a wide range of other multivariate time series with missing data and irregular sampling.
