A feeding trial was conducted to determine the growth performance and carcass characteristics of Japanese quails fed diets containing sorghum. A total of ninety of one-week old Japanese quail chicks were used for the experiment. Five diets were formulated in which sorghum was included at graded levels 0, 15, 30, 45 and 60% dietary levels designated as treatment 1, 2, 3, 4 and 5 respectively. The experimental period was five weeks when the birds reach six weeks of age.  The results of the growth performance showed significant differences (P<0.05) in the final body weight (161.70 – 180.10 g) and daily feed intake (21.34–25.12 g). Significant (P<0.05) differences was also observed in all carcass parameters measured except for dressing percentage. Liver weight and large intestine with T5 (65% total replacement) recorded the highest means value of 6.00 g and 6.66 g. Non-significant high values of feed conversion ratio were also obtained among the treatments. Treatment 1 (0%) and Treatment 5 (60%) showed better results in all parameters measured compared to other treatments. In conclusions, sorghum grain can play a significant role in formulating quail feed and can completely (60%) be used to replace maize without affecting the performance and carcass yield of the quails.

The purpose of this study was to investigate the effect of probiotic on fatty liver and metabolic endotoxemia in rats on high-fat diet. The rats were divided into three groups and fed one of the three diets (standard or control diet, high-fat diet, or high-fat+probiotic diet) for 16 weeks. At the end of this period, blood samples of the rats were taken and the liver tissue was removed for histopathology. There was an increase in the activities of both aspartate aminotransferase and alanine aminotransferase in the livers of rats on high-fat diet. However, only the rise in aspartate aminotransferase was blunted by incorporation of probiotics to the high-fat diet. Histopathological examination revealed 62.5% hepatosteatosis in high fat diet group and 12.5% in high-fat+probiotic diet group. In conclusion, the protective effect of probiotic supplement on liver steatosis caused by high-fat diet was histopathologically demonstrated; however, its effect on liver enzymes, inflammatory markers, and metabolic endotoxin was not observed. There is a need for further studies in terms of both dose and strain to recommend the use of probiotics in nonalcoholic fatty liver disease.

Desafios do funcionamento de conselhos deliberativos em reservas extrativistas marinhas na região bragantina do estado do Pará
Authors: De Sousa do Espirito Santo Ivanilde , Piraux Marc
Published: March 2021

O presente trabalho tem por objetivo analisar e comparar o funcionamento dos conselhos deliberativos das Reservas Extrativistas (RESEX) marinhas Caeté-Taperaçu e Araí-Peroba, a partir de alguns critérios da governança territorial. O estudo foi realizado nas RESEX Marinhas Caeté-Taperaçu (município de Bragança) e na Araí-Peroba (município de Augusto Corrêa), criadas em 2005, na região nordeste do estado do Pará. O trabalho foi elaborado a partir de uma abordagem qualitativa. A coleta de dados se deu através de dados secundários, questionários e entrevistas semi-estruturadas. Observou-se que, apesar das dificuldades, o conselho deliberativo da RESEX marinha Caeté-Taperaçu está funcionando, embora com uma gestão centralizada e ineficiente. Já o conselho deliberativo da RESEX marinha Araí-Peroba encontra-se inativo desde 2014. Os motivos foram: a falta de uma gestão descentralizada, o difícil acesso a RESEX, entendimento do significado de uma RESEX, forte assistencialismo e a política partidária. Conclui-se que, apesar da governança territorial ser uma inovação social para a gestão dos territórios de RESEX marinhas, nos conselhos deliberativos Caeté-Taperaçu e Araí-Peroba falta uma governança, visto que, identificou-se arranjos institucionais enfraquecidos e participações não efetivas das comunidades extrativistas no processo de decisão.

Authors: Hera Tanzina Rahman , Khan Md. Ashikur Rahman , Nath Nishu
Published: March 2021

Gestational Diabetes Mellitus (GDM) is defined as any degree of glucose intolerance with onset or first recognition during pregnancy. Fifty percent of GDM patients develop type 2 Diabetes in next twenty years and as well as the newborn can also be affected by diabetes in their lifetime. So the long term complications for both the mother and the child cannot be ignored. In view of maternal morbidity and mortality as well as fetal complications, early diagnosis is an utmost necessity in the present scenario. In developing country like Bangladesh, early detection and prevention is not cost effective and usually troublesome. So, there is an urgent need for a well-designed method for the detection of gestational diabetes mellitus. The purpose of this study is to predict the GDM in the first trimester. This research presents and compares some Artificial Neural Network (ANN) models on the early detection of Gestational diabetes mellitus and chooses the best neural network model among them to detect GDM early.

Fazekas Mihály azon – meglehetősen kisszámú – klasszikus szerzőnk közé tartozik, aki körül látszólag minden rendben van. Létezik műveinek kritikai kiadása (meglehetősen régről, 1955-ből) van róla nagymonográa is, Julow Viktor tollából. Julow a könyvét hosszas kutatások után, évtizedekkel a részben tőle is gondozott kritikai kiadás megjelenése után adta ki: ez a könyv azóta is jelentős teljesítménynek számít. Ezek alapján azt is mondhatnók, nem csoda, hogy az utóbbi időben csönd övezi az író alakját, hiszen minden tisztázva van körülötte. Pedig korántsem. Érdemes közelebb lépnünk Fazekas alakjához és teljesítményéhez, mert akkor jobban látszanak a hiányok és a repedések azon a szakirodalmi hagyományon, amely vele foglalkozott.
Fazekas Mihály: csillagászat és kortan
Authors: Zsoldos Endre
Published: March 2021

It is less known that the poet Mihály Fazekas was interested in astronomy and even published a calendar of his own. The Debreczeni Magyar Kalendariom (“Hungarian Calendar of Debrecen”) was a successful venture, surviving its founder by decades. Instead of the usual prognostications one finds in such calendars, Fazekas published popular astronomical articles of varying length. In these he described the properties of the members of the Solar System, gave their distance from the Earth, their periods, sizes etc. His point of view was definitely modern. Despite some errors originating probably from oversimplification, the calendar provided his readers with current information on the planets. His unpublished manuscripts confirm that he was well versed in mathematical calculations.
EXPERTOS EN FISIOLOGÍA: RESUMEN DE LO QUE DEBES SABER DE LAS HORMONAS TIROIDEAS

Published: March 2021

La glándula tiroides secreta dos hormonas importantes, la tiroxina y triyodotironina.  Se conoce ahora, una regulación más selectiva de la síntesis de triyodotironina a partir de la desyodación de tiroxina en los tejidos blanco; esto permite una mayor disponibilidad de hormona en un determinado tejido, de acuerdo con sus necesidades fisiológicas, o lo protege de los niveles exageradamente altos. La glándula tiroides tiene la capacidad de almacenar y autorregular el ingreso de yodo a la misma y de desviar la síntesis hormonal hacia la triyodotironina ante escasa ingesta de yodo.  Además de los receptores nucleares, se conocen otros receptores para las hormonas tiroideas, localizados en las mitocondrias y en la superficie de la membrana plasmática, y sus efectos son esenciales en el desarrollo, crecimiento y metabolismo.

Published: March 2021

En un contexto en el que la investigación artística en música (artistic research) se abre camino cada vez más rápido en el panorama educativo y en el que los estudiantes demandan nuevas propuestas centradas en la investigación en las artes musicales, este artículo explora la oferta educativa a nivel de doctorado que, en la actualidad, está vigente en universidades y conservatorios superiores de música en Europa.

Con un objetivo fundamentalmente práctico, se ofrece un estado de la cuestión que reflexiona sobre los parámetros fundamentales que todo estudiante que desee adentrarse en esta vía de investigación artística debe considerar. Asimismo, se recoge en una tabla adjunta la diversidad de títulos que contemplan este enfoque y se desglosan diversos parámetros que abarcan desde requisitos de admisión, hasta idiomas en los que se imparten estos estudios, créditos, duración, instituciones colaboradoras, formato de presencialidad, mecanismos de seguimiento, cuestiones relacionadas con la defensa de la tesis, áreas de estudio, precios y modalidades de financiación, entre otros aspectos. De esta manera, quienes se acerquen a este trabajo podrán seleccionar el centro que mejor se adecúe a sus necesidades, al mismo tiempo que obtendrán una visión global en torno al programa seleccionado.

En suma, este artículo ofrece respuestas a la demanda actual de los músicos en la búsqueda de programas doctorales que unifiquen tanto la vía interpretativa/compositiva como la de investigación, y que se alejen de los enfoques tradicionales que, a veces únicos hace poco tiempo, ofertaban los centros de enseñanza superior. No dudamos que, con el tiempo, tanto esta tabla como el artículo se ampliarán, en paralelo a la difusión y adaptación que los centros hagan con este nuevo enfoque de estudios que se abre paso de forma lenta pero segura.

GRAMMATICALIZATION OF NOUNS IN JORDANIAN ARABIC:
EVIDENCE FROM ʃIKIL AND OMIR
Authors: AL KAYED Murad
Published: March 2021

The current study aims at exploring the grammaticalization of the nouns ʃikil 'shape' and omir 'age' in Jordanian Arabic. The data were collected from Jordanian T.V. series and interviews with native speakers of Jordanian Arabic. The sample of the study consisted of 300 tokens of ʃikil and 200 tokens of omir. The researcher collected the data, then he analysed the functions of these two words. The study found out that ʃikil was used 100 times as a noun meaning 'shape', and 200 times as an evidential particle. Besides, omir was also used as a noun 60 times and 140 times as a negative polarity item. The findings of the study showed that ʃikil has one lexical meaning 'shape', and it evolved by the process of grammaticalization into an evidential particle. ʃikil underwent the process of semantic bleaching, since it lost its content meaning and developed to serve a grammatical function of evidentially. Bedsides, it was decategorized as it lost the grammatical features of nouns, i.e. it cannot be pluralized and cannot accept definite articles. Also ʃikil lost its stress as part of phonetic reduction. Similarly, omir has one lexical meaning 'age' and developed into a negative polarity item. Omir was affected by the process of semantic bleaching and decategorization as it was developed from its original meaning as a noun meaning 'age' into a negative polarity item. Additionally, omir underwent the process of phonetic reduction as it lost stress. The study found out that ʃikil and omir underwent three stages of grammaticalization: semantic bleaching, decategorization, and phonetic reduction.
SEMANTIC CLASSIFICATION OF METAPHORS IN UKRAINIAN AND ENGLISH INSCRIPTIONS ON CLOTHING
Authors: STRIUK Natalia
Published: March 2021

The present research is an attempt to analyse metaphors in English and Ukrainian clothing inscriptions in a comparative aspect. The study focuses on providing a sufficient semantic classification of this versatile figure of speech in the discourse that has never been analysed in terms of metaphors. It deals with English and Ukrainian metaphorical inscriptions on clothing harvested on the Internet over a two-year period (2017-2019). The paper shows that metaphorisation is unevenly typical of English and Ukrainian linguocultural environments. The peculiarities of the source from which the units under analysis were collected allows us to identify seven main vehicle-driven categories of metaphors employed in clothing inscriptions: anthropic, zoomorphic, botanomorphic, creaturemorphic, artefactomorphic, ecomorphic and sensory. The research proves that both English and Ukrainian metaphorical clothing inscriptions have their peculiar sources; moreover, even if metaphors are built on the same or similar images, the focus is usually quite different. This study argues that metaphors on clothing inscriptions can serve as an applicable source to study social priorities, values and tendencies of two different European linguocultural environments. The outcome of the research can be used as an interesting material for sociolinguistics and linguocultural studies.

Published: March 2021

Norwegian Lemming Lemmus lemmus is a remarkable population cycling species having a number of aposematic traits in coloration and behavior. This species was thought to be the only mammal endemic to Fennoscandia. Here, we report on the discovery of a distinct lineage of this species from Novaya Zemlya. This lineage is described here as the new subspecies Lemmus lemmus chernovi ssp. nov. that morphologically differs from the nominate subspecies by having a cryptic coloration. Our time-calibrated phylogeny revealed that this insular subspecies was isolated there since the Eemian interglacial (mean age 93 Ka). Hence, bright coloration and antipredator behavior of the nominate subspecies are novel aposematic traits that evolved since its isolation in a European refugium. This new discovery indicates that Novaya Zemlya supported a cryptic polar refugium for cold-adapted terrestrial fauna during the Pleistocene. Finally, our findings highlight that allopatric ranges of the true lemmings (Lemmus) reflect stepwise range expansions in cold climatic episodes with subsequent isolation in refugia during interglacial events.
Creative revolution transforms market and property relations
Authors:   Lomonosov Moscow State University, Buzgalin A.V.
Published: March 2021

The author describes the qualitative changes currently taking place in social production indicating that their basis is the creative revolution, the transition to the dominance of creative activity. The article shows creativity is a process of subjects’ subject, as a result of which unlimited public goods are created. So deep contradictions arise in the market development, property relations, values and the human motivation. Intellectual rents, instead of profit, begins to play an increasing role in capital accumulation, new forms of subordination of labor to capital and the phenomenon of exploitation by capital of world culture arise. The creative revolution creates the conditions in which the subject comparable in its creative (and destructive) power with capital, arises. This is a creative person but for him deep contradictions in the space of the total market and the capital hegemony, revealed by the author of the article, are typical.
Internal migration and strategic priorities of population increase in Russia's Far East
Authors:   Polytechnic Institute of Far Eastern Federal University, Beletsky A.A.
Published: March 2021

The article uses several indicators and their dynamics to assess economic development of Russian regions. The indicators are holistic and require solutions that would target regional strategic goals and tasks, as well as national interests. While there are numerous and diverse strategic development programs, the majority of them rely predominantly on the socioeconomic basis. These programs face a key resource restriction due to a nationwide population drop and escalating competition over human resources at all management levels. Regional strategies are often developed locally and do not account for actions of other relevant participants. The articles seeks to substantiate significant tendencies and observed trends as a basic stage in regional strategizing. The author analyzes existing strategic forecasts and substantiates activities for changing current trends in population size dynamics exhibited by the Far Eastern Federal District.
On priority development of knowledge economy
Authors:   Russian Presidential Academy of National Economy and Public Administration, Aganbegyan A.G.
Published: March 2021

A.G. Aganbegyan considers the knowledge economy as the main component of human capital. He analyzes certain areas of the knowledge economy (R&D, healthcare and education) by comparing relevant results demonstrated by Russian regions with similar indices reported for other countries. The article points out positive and negative aspects, e.g. high level and quality of education v. low efficiency of its application; lower cancer mortality rate and particularly child mortality rate v. high mortality from cardiovascular disease among working-age population, etc. Major causes of negative phenomena include insufficient funding of the public sector and inefficient administration. In order to remedy the situation, the author recommends the development of a new federal budget, transition to national economic planning and adjustment of national projects.
Confidence in the future as an economic development factor
Authors:   Central Economics and Mathematics Institute of the Russian Academy of Sciences, Dementyev V. E.
Published: March 2021

The level of confidence in the future is considered as one of the important characteristics of the quality of life. Social and economic well-being depends on what expectations prevail in a society. It is shown that the reduction of interest rates on loans is not a sufficient condition for overcoming investment pessimism. It is indicated that with low capacity utilization, cheap loans can lead to stagnation of industries, contributing to the preservation of the existing structure of used capacities. The quality of coordination of economic activity is considered as one of the factors of business confidence in the future. It is noted that the competitiveness of existing industries has a great impact on the formation of new industries in the economy. It is emphasized that the transition to the system of interactive strategic planning remains an urgent task for our country.
Contradictions of the upcoming period: points for developing the agenda for medium- and long-term perspective
Authors:   Analysis and Forecasting of Macroeconomic Processes at the Institute of Economic Forecasting of the RAS, Belousov D.M.
Published: March 2021

Analysis of the economic and social situation allows for the conclusion that the world is entering an era of global instability and contradictions. There is clearly a crisis of compensatory and basic institutions. Humans cease to be the subjects of the historical process and instead are becoming the object of control. Contradictions are sharply increasing at different levels. We are witnessing the conflict between labor and capital related to the national nature of labor and the global nature of capital. Production, security and regional applied science are changing, but financial and institutional systems remain global. Information and trade wars are intensifying. During a multi-level crisis, it is difficult to predict what a new social order will be like, but the transition to it will be difficult and highly possibly rife with (macro-) regional conflicts.

Cometary Activity Begins at Kuiper Belt Distances: Evidence from C/2017 K2
Authors: Jewitt David , Kim Yoonyoung , Mutchler Max , Agarwal Jessica , Li Jing , Weaver Harold
Published: March 2021

We study the development of activity in the incoming long-period comet C/2017 K2 over the heliocentric distance range 9 ≲ r

H
≲ 16 au. The comet continues to be characterized by a coma of submillimeter-sized and larger particles ejected at low velocity. In a fixed co-moving volume around the nucleus we find that the scattering cross section of the coma, C, is related to the heliocentric distance by a power law,

, with heliocentric index s = 1.14 ± 0.05. This dependence is significantly weaker than the r

H

−2 variation of the insolation as a result of two effects. These are, first, the heliocentric dependence of the dust velocity and, second, a lag effect due to very slow-moving particles ejected long before the observations were taken. A Monte Carlo model of the photometry shows that dust production beginning at r

H
∼ 35 au is needed to match the measured heliocentric index, with only a slight dependence on the particle size distribution. Mass-loss rates in dust at 10 au are of order 103 kg s−1, while loss rates in gas may be much smaller, depending on the unknown dust to gas ratio. Consequently, the ratio of the nongravitational acceleration to the local solar gravity, α′, may, depending on the nucleus size, attain values of ∼10−7 ≲ α′ ≲ 10−5, comparable to values found in short-period comets at much smaller distances. Nongravitational acceleration in C/2017 K2 and similarly distant comets, while presently unmeasured, may limit the accuracy with which we can infer the properties of the Oort cloud from the orbits of long-period comets.
Gyro-kinematic Ages for around 30,000 Kepler Stars
Authors: Lu Yuxi (Lucy) , Angus Ruth , Curtis Jason L. , David Trevor J. , Kiman Rocio
Published: March 2021

Estimating stellar ages is important for advancing our understanding of stellar and exoplanet evolution and investigating the history of the Milky Way. However, ages for low-mass stars are hard to infer as they evolve slowly on the main sequence. In addition, empirical dating methods are difficult to calibrate for low-mass stars as they are faint. In this work, we calculate ages for Kepler F, G, and crucially K and M dwarfs, using their rotation and kinematic properties. We apply the simple assumption that the velocity dispersion of stars increases over time and adopt an age–velocity-dispersion relation (AVR) to estimate average stellar ages for groupings of coeval stars. We calculate the vertical velocity dispersion of stars in bins of absolute magnitude, temperature, rotation period, and Rossby number and then convert velocity dispersion to kinematic age via an AVR. Using this method, we estimate gyro-kinematic ages for 29,949 Kepler stars with measured rotation periods. We are able to estimate ages for clusters and asteroseismic stars with an rms of 1.22 Gyr and 0.26 Gyr respectively. With our Astraea machine-learning algorithm, which predicts rotation periods, we suggest a new selection criterion (a weight of 0.15) to increase the size of the McQuillan et al. catalog of Kepler rotation periods by up to 25%. Using predicted rotation periods, we estimated gyro-kinematic ages for stars without measured rotation periods and found promising results by comparing 12 detailed age–element abundance trends with literature values.
The Effects of Three-dimensional Radiative Transfer on the Resonance Polarization of the Ca i 4227 Å Line
Authors: Jaume Bestard J. , Trujillo Bueno J. , Štěpán J. , del Pino Alemán T.
Published: March 2021

The sizable linear polarization signals produced by the scattering of anisotropic radiation in the core of the Ca i 4227 Å line constitute an important observable for probing the inhomogeneous and dynamic plasma of the lower solar chromosphere. Here we show the results of a three-dimensional (3D) radiative transfer complete frequency redistribution investigation of the line’s scattering polarization in a magnetohydrodynamical 3D model of the solar atmosphere. We take into account not only the Hanle effect produced by the model’s magnetic field but also the symmetry breaking caused by the horizontal inhomogeneities and macroscopic velocity gradients. The spatial gradients of the horizontal components of the macroscopic velocities produce very significant forward scattering polarization signals without the need of magnetic fields, while the Hanle effect tends to depolarize them at the locations where the model’s magnetic field is stronger than about 5 G. The standard 1.5D approximation is found to be unsuitable for understanding the line’s scattering polarization, but we introduce a novel improvement to this approximation that produces results in qualitative agreement with the full 3D results. The instrumental degradation of the calculated polarization signals is also investigated, showing what we can expect to observe with the Visible Spectro-Polarimeter at the upcoming Daniel K. Inouye Solar Telescope.

P

P
0 from Atacama Large Millimeter/submillimeter Array observations. We aim to test if the same gas-mass calibration adopted in field galaxies can be applied to protocluster galaxies. Five galaxies out of 16 targeted galaxies are detected in the [C i] line, and these are all previously detected in CO (3–2) and CO (4–3) and three in 1.1 mm dust continuum. We investigate the line luminosity relations between CO and [C i] in the protocluster and compare with other previous studies. We then compare the gas mass based on three gas tracers of [C i], CO(3–2), and dust if at least one of the last two tracers are available. Using the calibration adopted for field main-sequence galaxies, the [C i]-based gas measurements are lower than or comparable to the CO-based gas measurements by −0.35 dex at the lowest with the mean deviation of −0.14 dex. The differences between [C i]- and the dust- based measurements are relatively mild by up to 0.16 dex with the mean difference of 0.02 dex. Taking these all together with calibration uncertainties, with the [C i] line, we reconfirm our previous findings that the mean gas fraction is comparable to field galaxies for a stellar-mass range of

. However, at least for these secure five detections, the depletion timescale decreases more rapidly with stellar mass than field galaxies that might be related to earlier quenching in dense environments.
A Complex Luminosity Function for the Anomalous Globular Clusters in NGC 1052-DF2 and NGC 1052-DF4

Published: March 2021

NGC 1052-DF2 and NGC 1052-DF4 are ultradiffuse galaxies that have extremely low velocity dispersions, indicating that they have little or no dark matter. Both galaxies host anomalously luminous globular clusters (GCs), with a peak magnitude of their GC luminosity function (GCLF) that is ∼1.5 mag brighter than the near-universal value of M

V
≈ −7.5. Here we present an analysis of the joint GCLF of the two galaxies, making use of new Hubble Space Telescope photometry and Keck spectroscopy and a recently improved distance measurement. We apply a homogeneous photometric selection method to the combined GC sample of DF2 and DF4. The new analysis shows that the peak of the combined GCLF remains at M

V
≈ −9 mag. In addition, we find a subpopulation of less luminous GCs at M

V
≈ −7.5 mag, where the near-universal GCLF peak is located. The number of GCs in the magnitude range of −5 to −8 is

in DF2 and

in DF4, similar to that expected from other galaxies of the same luminosity. The total GC number between M

V
of −5 and −11 is

for DF2 and

for DF4, calculated from the background-subtracted GCLF. The data are consistent with both galaxies having two GC populations: the one expected for their luminosity, and a very luminous population composing ∼90% of the total cluster mass. The number of GCs does not scale with the halo mass in either DF2 or DF4, suggesting that N
GC is not directly determined by the merging of halos.

We observe 1.3 mm spectral lines at 2000 au resolution toward four massive molecular clouds in the Central Molecular Zone (CMZ) of the Galaxy to investigate their star formation activities. We focus on several potential shock tracers that are usually abundant in protostellar outflows, including SiO, SO, CH3OH, H2CO, HC3N, and HNCO. We identify 43 protostellar outflows, including 37 highly likely ones and 6 candidates. The outflows are found toward both known high-mass star-forming cores and less massive, seemingly quiescent cores, while 791 out of the 834 cores identified based on the continuum do not have detected outflows. The outflow masses range from less than 1 M
⊙ to a few tens of M
⊙, with typical uncertainties of a factor of 70. We do not find evidence of disagreement between relative molecular abundances in these outflows and in nearby analogs such as the well-studied L1157 and NGC 7538S outflows. The results suggest that (i) protostellar accretion disks driving outflows ubiquitously exist in the CMZ environment, (ii) the large fraction of candidate starless cores is expected if these clouds are at very early evolutionary phases, with a caveat on the potential incompleteness of the outflows, (iii) high-mass and low-mass star formation is ongoing simultaneously in these clouds, and (iv) current data do not show evidence of a difference between the shock chemistry in the outflows that determines the molecular abundances in the CMZ environment and in nearby clouds.

We present extensive, well-sampled optical and ultraviolet photometry and optical spectra of the Type Ia supernova (SN Ia) 2017hpa. The light curves indicate that SN 2017hpa is a normal SN Ia with an absolute peak magnitude of

−19.12 ± 0.11 mag and a postpeak decline rate Δm
15(B) = 1.02 ± 0.07 mag. According to the quasi-bolometric light curve, we derive a peak luminosity of 1.25 × 1043 erg s−1 and a 56Ni mass of 0.63 ± 0.02 M
⊙. The spectral evolution of SN 2017hpa is similar to that of normal Ia supernovae (SNe Ia), while it exhibits an unusually rapid velocity evolution resembling that of SN 1991bg-like SNe Ia or the high-velocity subclass of SNe Ia, with a postpeak velocity gradient of ∼130 ± 7 km s−1 day−1. Moreover, its early spectra (t < − 7.9 days) show a prominent C ii
λ6580 absorption feature, which disappeared in near-maximum-light spectra but reemerged at phases from t ∼ + 8.7 days to t ∼ + 11.7 days after maximum light. This implies that some unburned carbon may mix deep into the inner layer and is supported by the low C ii
λ6580-to-Si ii
λ6355 velocity ratio (∼0.81) observed in SN 2017hpa. The O i
λ7774 line shows a velocity distribution like that of carbon. The prominent carbon feature, the low velocity seen in carbon and oxygen, and the large velocity gradient make SN 2017hpa stand out from other normal SNe Ia and are more consistent with predictions from a violent merger of two white dwarfs. Detailed modeling is still needed to reveal the nature of SN 2017hpa.
Effects of Forcing Mechanisms on the Multiscale Properties of Magnetohydrodynamics

Published: March 2021

We performed numerical simulations to study the response of magnetohydrodynamics (MHD) to large-scale stochastic forcing mechanisms parameterized by one parameter, 0 ≤ a ≤ 1, going from direct injection on the velocity field (a = 1) to stirring acts on the magnetic field only (a = 0). We study the multiscale properties of the energy transfer by splitting the total flux in channels mediated by (i) the kinetic nonlinear advection, (ii) the Lorentz force, (iii) the magnetic advection, and (iv) the magnetic stretching term. We further decompose the fluxes into two subchannels given by heterochiral and homochiral components in order to distinguish forward, inverse, and flux-loop cascades. We show that there exists a quasi-singular role of the magnetic forcing mechanism for a ∼ 1: a small injection on the magnetic field a < 1 can strongly deplete the mean flux of kinetic energy transfer throughout the kinetic nonlinear advection channel. We also show that this negligible mean flux is the result of a flux-loop balance between heterochiral (direct) and homochiral (inverse) transfers. Conversely, both homochiral and heterochiral channels transfer energy forward for the other three channels. Cross-exchange between velocity and the magnetic field is reversed around a = 0.4, and except when a ∼ 1, we always observe that heterochiral mixed velocity–magnetic energy triads tend to move energy from magnetic to velocity fields. Our study is an attempt to further characterize the multiscale nature of MHD dynamics by disentangling different properties of the total energy transfer mechanisms, which can be useful for improving subgrid modeling.
Oceanic Superrotation on Tidally Locked Planets
Authors: Zeng Yaoxuan , Yang Jun
Published: March 2021

Is there oceanic superrotation on exoplanets? Atmospheric superrotation, characterized by west-to-east winds over the equator, is a common phenomenon in the atmospheres of Venus, Titan, Saturn, Jupiter, and tidally locked exoplanets. The stratospheric atmosphere of Earth is also superrotating during the westerly phase of the quasi-biennial oscillation. However, whether the same phenomenon can occur in the ocean is poorly known. Through numerical simulations, here we show that oceanic superrotation does occur on tidally locked terrestrial planets around low-mass stars. Its formation (spun up from rest) is associated with surface winds, the equatorward momentum convergence by Rossby waves, and the eastward propagation of Kelvin waves in the ocean. Its maintenance is driven by equatorward momentum transports of coupled Rossby–Kelvin waves in the ocean excited from the uneven stellar radiation distribution. The width of the superrotation is mainly constrained by the Rossby deformation radius in the ocean, while its strength is more complex. Many factors can influence the strength, including planetary rotation rate, stellar flux, greenhouse gas concentration, seawater salinity, and bottom drag, but a scaling theory for the strength of the oceanic superrotation is lacking. This work confirms that oceanic superrotation can occur on tidally locked terrestrial planets with seawater oceans and suggests that it may also occur on tidally locked hot planets with magma oceans that will possibly be observed in the near future.
New Bistable Solutions in Molecular Cloud Chemistry: Nitrogen and Carbon Autocatalysis
Authors: Dufour Gwenaëlle , Charnley Steven B.
Published: March 2021

We have investigated the chemistry of dense interstellar clouds and found new bistable solutions in the nitrogen and carbon chemistries. We identify the autocatalytic processes that are present in the pure, reduced, chemical networks and find, as previously found for oxygen chemistry, that He+ plays an important role. The applicability of these results to astronomical environments is briefly discussed. The bistable solutions found for carbon chemistry occur for low densities and high ionization fractions that are not compatible with those found in cold, dense clouds. Bistability in the pure nitrogen chemistry occurs for conditions that are relevant for prestellar cores in which significant CO depletion has taken place. We conclude that several autocatalyses are embedded in gas-phase interstellar chemistry and that many more are potentially present.

DNA barcode datasets are a useful tool for conservation and aid in taxonomic identification, particularly in megadiverse tropical countries seeking to document and describe its biota, which is dropping at an alarming rate during recent decades. Here we report the barcodes for several low elevation bird species from northern Colombia with the goal to provide tools for species identification in this region of South America. We blood sampled birds in a lowland tropical forest with various degrees of intervention using standard 10 × 12 mist-nets. We extracted DNA and sequenced the COI barcode gene using standard primers and laboratory methods. We obtained 28 COI sequences from 19 species, 10 families and 3 orders and found that barcodes largely matched (but not always) phenotypic identification (>90%) and they also facilitated the identification of several challenging passerine species. Despite our reduced sampling, our study represents the first attempt to document COI barcodes for birds (from blood samples) in this part of Colombia, which fills a considerable gap of sampling in this part of South America.

Authors: Granjon Evelyn
Published: March 2021

La thérapie familiale psychanalytique est une psychanalyse groupale d’une famille en souffrance. La situation de groupe et les conditions psychanalytiques proposées font du groupe thérapeutique, le néo-groupe, le lieu de reprise et d’élaboration de ce qui est hors d’atteinte dans la famille, aliène ses membres et fait souffrir la famille. À partir des travaux de R. Kaës, O. Avron, J. Puget ainsi que de l’apport de maints psychanalystes familiaux, l’auteure propose une approche des processus et des enjeux de la constitution du néogroupe et du travail d’analyse permettant de penser la famille et de penser en famille.
