Deep eutectic solvents (DES) are biologically safe solvents containing donors and acceptors of hydrogen bonds.They are considered promising alternative solvents used in the extraction of biologically active substances from plants.To characterize extracts, spectrophotometric methods based on various complexation reactions are used, such as quantitative determination of the total content of flavonoids, polyphenols, determination of the total antioxidant activity. However, the articles indicate calibration characteristics for aqueous or ethanol solutions of standard substances, and no calibration dependencies were found in the DES medium. The question of the validity of the application of calibration characteristics using ethanol solutions for DES remains open. Therefore, the aim of our work was to assess the effect of the presence of deep eutectic solvents on the applicability of methods for determining polyphenols, flavonoids and total antioxidant activity. In the course of the work, calibration dependences were obtained in the medium of deep eutectic solvents based on choline chloride and malonic, malic, citric and tartaric acids. It has been established that the nature of the solvent strongly influences the calibration coefficients, which indicates the need to use separate graduations for each type of solvent.

The dependence of photoluminescence of nominally pure and Zn (Mg)-doped lithium niobate crystals on composition, kind, concentration of doped element and doping technology, was observed. The photoluminescence did not depend on doped element kind and was decreased with increasing in stoichiometry. A decrease in the luminescence of NbNb–NbLi centers was observed in weakly Zn (Mg)-doped LiNbO3 crystals, the emission of NbNbO6 groups dominated in strongly ones. LiNbO3 : Zn (Mg) crystals obtained by homogeneous doping had the emission of both NbNb — NbLi centers and NbNbO6-groups.

Authors: Hacini Abdelbaki , Hadi Ali Ahmad , Adnan Nurul Nadia , Nayan Nafarizal
Published: December 2022

ITO/Mo bilayer thin films were sputtered on n-type silicon and glass substrates and annealed with a Nd:YAG pulsed laser. The structural results show that both the as-deposited and the annealed ITO/Mo thin films have a polycrystalline structure, and that the annealing treatment enhanced the crystallinity of samples. Moreover, the XRD patterns exhibited a cubic structure preferentially oriented along the (222) and (400) planes. The AFM analysis shows that grain size and RMS roughness increased from 16.02 to 36.19 nm and 0.4 to 2.6 nm, respectively, when the laser energy was increased to 120 mJ. The as-deposited sample has an optical transmittance of nearly 80% in the 300–800 nm range. The laser annealing yielded a higher transmittance of 94% and increased the bandgap energy from 2.76 to 2.88 eV at 120 mJ. The annealing treatment decreased the resistivity from 15.63 × 10−4 to 1.73 × 10−4 Ω/cm−1. Additionally, the figure of merit of the ITO/Mo structure improved significantly from 6.63 × 10−4 Ω−1 of the as-deposited sample to 17.6 × 10−3 Ω−1 of the the annealed structure. The results indicate that the laser annealing could improve the efficiency of the transparent conductive layer, which can be potentially applied in optoelectronic devices.
Biosemiotics in the Epoch of Post-Anthropocentrism
Authors: Strugovshchikova U.S.
Published: December 2022

Biosemiotics is a theoretical approach that makes a research on signs, sign systems and semantic processes of the biosphere. It provides a conceptual framework for describing biological phenomena at all levels of the organization of life, and its relevance may be due to the unstable relationship between culture and nature. We are able to use this approach to initiate safe cultural forms and practices. Biosemiotic approach makes it possible to combine cultural and semiotic concepts with biological and biosemiotic frames in the relevance to ecosemiotics, as we are able to update cultural civilizational meanings and identify new vectors of human’s civilization development in the epoch of the post-anthropocentrism

Published: December 2022

Aim: Undescended testis is a congenital genitourinary system pathology characterized by the absence of testis in the scrotum. In this disease, the heat stress caused by the testes not being at the optimal temperature can trigger oxidative stress and inflammation. Our study investigated the status of oxidative stress and inflammation markers between patients with undescended testes and healthy infants.Materials and Methods: Fifty pediatric patients with undescended testes and a control group who applied to Pediatric Surgery Clinic were included in the study. From the blood samples, oxidative stress and inflammation status were examined. Interleukin 1 beta, interleukin 6, and tumor necrosis factor alpha levels of inflammation parameters were measured by the ELISA method using commercial kits. Total oxidant status, total antioxidant status, total thiol, and native thiol levels were measured photometrically with commercial kits. Oxidative stress index and disulfide levels were calculated with a mathematical formula. Oxidative stress and inflammation marker levels of the patient and healthy groups were compared statistically. Results: Total antioxidant status, total thiol, and native thiol levels were statistically significantly lower in the patient group than the healthy group (p<0.05). Total antioxidant status, oxidative stress index, disulfide levels, and interleukin 1β, interleukin 6 levels were also statistically significantly higher in the patient group (p<0.05). There was no difference in tumor necrosis factor-α levels between the groups.Conclusion: In our study, it was observed that oxidative stress and inflammation were higher in patients with undescended testes. Since this situation may lead to systemic diseases in the future, more extensive studies are needed.
INITIATION, RACE RELATIONS AND OTHERNESS IN TONI MORRISON’S “RECITATIF”
Authors: TABUR Şemsettin
Published: December 2022

The moments of change marking transformation from childhood to adulthood, from innocence to experience and gaining knowledge about the self and the world in general have been seen as of significance across cultures. Correspondingly, literature, art in general, has engaged closely with this ritualistic, threshold experience. Foregrounding a moment of change and centering its plot around at least one young adolescent or child, initiation stories, or more commonly known as stories of coming of age, narrativize the theme of growing up or at least one, major character’s realization of a truth about him/herself as well as the life and the world condition. Despite the prevalence of initiation theme in literature and the significant attempts made by literary studies scholars to theorize what constitutes an initiation story especially until a few decades ago, more recent scholarship, Anglophone literary studies at least, has dealt less considerably with initiation as a frame of reference in the analysis and interpretation of literary texts. The present study reconsiders the theme of initiation in literature through Toni Morrison’s “Recitatif” and examines how the short story deviates from the patterns of traditional initiation stories. It is argued that Morrison interestingly brings together the issue of initiation with concepts such as race relations and otherness, which calls for a more dynamic, relational and intersubjective understanding of the term.

Depression, Anxiety, Stress and Physical Activity: A Cross-Sectional Analysis of Adults
Authors: ARIKAN Ali , ÇAKIR Gökhan
Published: December 2022

The study aimed to examine the anxiety, depression, and stress levels of adults with different physical activity levels. The data of the study were collected through the Personal Information Form, International Physical Activity Questionnaire-Short Form (IPAQ-SF) and Depression, Anxiety, Stress Scale (DASS-21). After obtaining the necessary ethics committee approval for the study, data were collected from 55 of 81 provinces in Turkey by online method and convenient sampling. The sample of the study consisted of 488 adult individuals who filled the scales completely. Data obtained from adult individuals were analysed by using the SPSS (Statistical Package for Social Sciences) 26.0 program. Before the analyses, the assumptions required for the MANOVA test were discussed. After the necessary examinations were performed, descriptive statistics and the MANOVA test were used in the analysis of the data regarding the mean scores of the answers given by 488 adult individuals to the scales.

Most of the individuals participating in the study had normal scores for anxiety (70.7%), depression (64.3%) and stress (77.5%). Despite this situation, it was observed that there were individuals with severe and very advanced anxiety (11.5%), depression (12.3%) and stress (9.4%) score ranges. In terms of physical activity levels, 56.9% (n=278) of the participants were found to be inactive and minimally active. The hypothesis test results showed that the anxiety, depression and stress levels of inactive individuals were significantly higher than those in the minimally active and very active groups. As a result, it can be said that there was a strong link between physical activity and negative emotions for adults.

Cosmic dust plays a dominant role in the universe, especially in the formation of stars and planetary systems. Furthermore, the surface of cosmic dust grains is the benchwork where molecular hydrogen and simple organic compounds are formed. We manipulate individual dust particles in a water solution by contactless and noninvasive techniques such as standard optical and Raman tweezers, to characterize their response to mechanical effects of light (optical forces and torques) and to determine their mineral compositions. Moreover, we show accurate optical force calculations in the T-matrix formalism highlighting the key role of composition and complex morphology in the optical trapping of cosmic dust particles.

We apply a statistical deconvolution of the parallax errors based on Lucy’s inversion method (LIM) to the Gaia DR3 sources to measure their 3D velocity components in the range of Galactocentric distances R between 8 and 30 kpc with their corresponding errors and rms values. We find results that are consistent with those obtained by applying LIM to the Gaia DR2 sources, and we conclude that the method gives convergent and more accurate results by improving the statistics of the data set and lowering observational errors. The kinematic maps reconstructed with LIM up to R ≈ 30 kpc show that the Milky Way is characterized by asymmetrical motions with significant gradients in all velocity components. Furthermore, we determine the Galaxy rotation curve V

C
(R) up to ≈27.5 kpc with the cylindrical Jeans equation assuming an axisymmetric gravitational potential. We find that V

C
(R) is significantly declining up to the largest radius investigated. Finally, we also measure V

C
(R) at different vertical heights, showing that, for R < 15 kpc, there is a marked dependence on Z, whereas at larger R the dependence on Z is negligible.

We present ∼10–40 μm SOFIA-FORCAST images of 11 isolated protostars as part of the SOFIA Massive (SOMA) Star Formation Survey, with this morphological classification based on 37 μm imaging. We develop an automated method to define source aperture size using the gradient of its background-subtracted enclosed flux and apply this to build spectral energy distributions (SEDs). We fit the SEDs with radiative transfer models, developed within the framework of turbulent core accretion (TCA) theory, to estimate key protostellar properties. Here, we release the sedcreator python package that carries out these methods. The SEDs are generally well fitted by the TCA models, from which we infer initial core masses M

c
ranging from 20–430 M
⊙, clump mass surface densities Σcl ∼ 0.3–1.7 g cm−2, and current protostellar masses m
* ∼ 3–50 M
⊙. From a uniform analysis of the 40 sources in the full SOMA survey to date, we find that massive protostars form across a wide range of clump mass surface density environments, placing constraints on theories that predict a minimum threshold Σcl for massive star formation. However, the upper end of the m
*−Σcl distribution follows trends predicted by models of internal protostellar feedback that find greater star formation efficiency in higher Σcl conditions. We also investigate protostellar far-IR variability by comparison with IRAS data, finding no significant variation over an ∼40 yr baseline.

A challenge in characterizing active region (AR) coronal heating is in separating transient (bursty) loop heating from the diffuse background (steady) heating. We present a method of quantifying coronal heating’s bursty and steady components in ARs, applying it to Fe xviii (hot 94) emission of an AR observed by the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory. The maximum-, minimum-, and average-brightness values for each pixel, over a 24 hr period, yield a maximum-brightness map, a minimum-brightness map, and an average-brightness map of the AR. Running sets of such three maps come from repeating this process for each time step of running windows of 20, 16, 12, 8, 5, 3, 1, and 0.5 hr. From each running window’s set of three maps, we obtain the AR’s three corresponding luminosity light curves. We find (1) the time-averaged ratio of minimum-brightness-map luminosity to average-brightness-map luminosity increases as the time window decreases, and the time-averaged ratio of maximum-brightness-map luminosity to average-brightness-map luminosity decreases as the window decreases; (2) for the 24 hr window, the minimum-brightness map’s luminosity is 5% of the average-brightness map’s luminosity, indicating that at most 5% of the AR’s hot 94 luminosity is from heating that is steady for 24 hr; (3) this upper limit on the fraction of the hot 94 luminosity from steady heating increases to 33% for the 30 minute running window. This requires that the heating of the 4–8 MK plasma in this AR is mostly in bursts lasting less than 30 minutes: at most a third of the heating is steady for 30 minutes.

Spiral arms serve crucial purposes in star formation and galaxy evolution. In this paper, we report the identification of “A2744-DSG-z3,” a dusty, multiarm spiral galaxy at z = 3.059 using the James Webb Space Telescope (JWST) NIRISS imaging and grism spectroscopy. A2744-DSG-z3 was discovered as a gravitationally lensed submillimeter galaxy with the Atacama Large Millimeter/submillimeter Array (ALMA). This is the most distant stellar spiral structure seen thus far, consistent with cosmological simulations that suggest z ≈ 3 as the epoch when spirals emerge. Thanks to the gravitational lensing and excellent spatial resolution of JWST, the spiral arms are resolved with a spatial resolution of ≈290 pc. Based on spectral energy distribution fitting, the spiral galaxy has a delensed star formation rate of 85 ± 30 M
⊙ yr−1, and a stellar mass of ≈1010.6
M
⊙, indicating that A2744-DSG-z3 is a main-sequence galaxy. After fitting the spiral arms, we find a stellar effective radius (R
e,star) of 5.0 ± 1.5 kpc. Combining with ALMA measurements, we find that the effective radii ratio between dust and stars is ≈0.4, similar to those of massive star‐forming galaxies (SFGs) at z ∼ 2, indicating a compact dusty core in A2744-DSG-z3. Moreover, this galaxy appears to be living in a group environment: including A2744-DSG-z3, at least three galaxies at z = 3.05–3.06 are spectroscopically confirmed by JWST/NIRISS and ALMA, residing within a lensing-corrected projected scale of ≈70 kpc. This, along with the asymmetric brightness profile, further suggests that the spiral arms may be triggered by minor-merger events at z ≳ 3.

Using the first epoch of four-band NIRCam observations obtained by the James Webb Space Telescope (JWST) Prime Extragalactic Areas for Reionization and Lensing Science Program in the Spitzer IRAC Dark Field, we search for F150W and F200W dropouts. In 14.2 arcmin2, we have found eight F150W dropouts and eight F200W dropouts, all brighter than 27.5 mag (the brightest being ∼24 mag) in the band to the red side of the break. As they are detected in multiple bands, these must be real objects. Their nature, however, is unclear, and characterizing their properties is important for realizing the full potential of JWST. If the observed color decrements are due to the Lyman break, these objects should be at z ≳ 11.7 and z ≳ 15.4, respectively. The color diagnostics show that at least four F150W dropouts are far away from the usual contaminators encountered in dropout searches (red galaxies at much lower redshifts or brown dwarf stars). While the diagnostics of the F200W dropouts are less certain due to the limited number of passbands, at least one of them is likely not a known type of contaminant, and the rest are consistent with either high-redshift galaxies with evolved stellar populations or old galaxies at z ≈ 3–8. If a significant fraction of our dropouts are indeed at z ≳ 12, we have to face the severe problem of explaining their high luminosities and number densities. Spectroscopic identifications of such objects are urgently needed.

The question of what heats the solar chromosphere and corona remains one of the most important puzzles in solar physics and astrophysics. Up to now, two mechanisms are considered to work in heating the chromosphere and corona: magnetic reconnection and wave (turbulent flow) dissipation. But it is still not understood which mechanism is dominant. To solve the heating problem, one important topic at this stage is that we should understand how much energy is contributing from the two mechanisms respectively to the heating. In the quiet Sun, the thermal energy signal is observed as brightenings. Here we report two kinds of bright knots with a total of 3605 in the chromosphere of the quiet Sun, using the data from the New Vacuum Solar Telescope at Yunnan Observatories. The first kind of 1537 bright knots, which is first detected in chromospheric fibrils where waves and their dissipation are ubiquitous, propagates along these fibrils with velocities from 5 to 69 km s−1. The second kind of 2068 knots keeps stationary, and always appears at the footpoints of these fibrils where network magnetic fields exist, suggesting that magnetic reconnection locally produces these stationary knots. Based on the observations of thousands of bright knots, we display the different distribution patterns of the two kinds of bright knots in the quiet Sun, and deduce that half of the energy for heating the chromosphere is supplied by wave dissipation, and the other half by magnetic reconnection.

We present Atacama Large Millimeter/submillimeter Array observations with a 800 au resolution and radiative-transfer modeling of the inner part (r ≈ 6000 au) of the ionized accretion flow around a compact star cluster in formation at the center of the luminous ultracompact H ii region G10.6-0.4. We modeled the flow with an ionized Keplerian disk with and without radial motions in its outer part, or with an external Ulrich envelope. The Markov Chain Monte Carlo fits to the data give total stellar masses M

converge to v

r,0 ≈ 8.7 km s−1, or about the speed of sound of ionized gas, indicating that this gas is marginally unbound at most. From additional constraints on the ionizing-photon rate and far-IR luminosity of the region, we conclude that the stellar cluster consists of a few massive stars with M
star = 32–60 M
⊙, or one star in this range of masses accompanied by a population of lower-mass stars. Any active accretion of ionized gas onto the massive (proto)stars is residual. The inferred cluster density is very large, comparable to that reported at similar scales in the Galactic center. Stellar interactions are likely to occur within the next million years.

We present Hubble Space Telescope imaging of 14 gas-rich, low-surface-brightness galaxies in the field at distances of 25–36 Mpc, with mean effective radii and g-band central surface brightnesses of 1.9 kpc and 24.2 mag arcsec−2. Nine meet the standard criteria to be considered ultra-diffuse galaxies (UDGs). An inspection of point-like sources brighter than the turnover magnitude of the globular cluster luminosity function and within twice the half-light radii of each galaxy reveals that, unlike those in denser environments, gas-rich, field UDGs host very few old globular clusters (GCs). Most of the targets (nine) have zero candidate GCs, with the remainder having one or two candidates each. These findings are broadly consistent with expectations for normal dwarf galaxies of similar stellar mass. This rules out gas-rich, field UDGs as potential progenitors of the GC-rich UDGs that are typically found in galaxy clusters. However, some in galaxy groups may be directly accreted from the field. In line with other recent results, this strongly suggests that there must be at least two distinct formation pathways for UDGs, and that this subpopulation is simply an extreme low surface brightness extension of the underlying dwarf galaxy population. The root cause of their diffuse stellar distributions remains unclear, but the formation mechanism appears to only impact the distribution of stars (and potentially dark matter), without strongly impacting the distribution of neutral gas, the overall stellar mass, or the number of GCs.
