Updated Spin and Orbital Parameters and Energy Dependent Pulse Behaviors of the Accreting Millisecond X-Ray Pulsar IGR J17591–2342
Authors: Tse Kaho , Chou Yi , Hsieh Hung-En
Published: August 2020

We present our work in updating the spin and orbital parameters for the newly discovered accreting millisecond X-ray pulsar (AMXP) IGR J17591–2342 through pulsar timing and analyzing its energy dependent pulse behaviors. The data being analyzed were collected by Neutron Star Interior Composition ExploreR, which observed this AMXP from 2018 August to October. Using the pulse arrival time delay technique, more accurate spin and orbital parameters were evaluated. From the measured spin frequency derivative, it is estimated that the magnetic field of the neutron star in IGR J17591–2342 is approximately 4 × 108 G. Precise pulse profiles can be made using the updated spin and orbital parameters. The soft phase lag phenomenon that is usually seen in other AMXPs is also observed from ∼4 to 12 keV with a value of 0.06 cycles (1.14 μs). Additionally, the pulsed fractional amplitude increases from 1 to ∼5 keV and then decreases for higher energy bands. We found that these phenomena, as well as the energy spectrum, can be explained by the two-component model with a relatively strong blackbody component and an additional unpulsed disk blackbody component.

We present here the analysis of giant micropulses from the Vela pulsar. A total of 4187 giant micropulses with peak flux density >2.5 Jy were detected during almost 4 hr of observations carried out with the Yunnan 40 m radio telescope at 6800 MHz. Nine of the giant micropulses arrived approximately 3–4 ms earlier than the peak of average pulse profile, longer than that at lower frequencies. The remaining giant micropulses were clustered into three distributions that correspond to three main emission regions, including four giant micropulses occurring on the trailing edge of the averaged profile. We find that the peak flux density distribution follows a power law with index α ≈ −4. Furthermore, a certain amount of memory is present from the giant micropulse waiting time distribution. Possible emission mechanisms are discussed.

We derive a UV-optical stellar dust attenuation curve of galaxies at z = 1.4–2.6 as a function of gas-phase metallicity. We use a sample of 218 star-forming galaxies, excluding those with very young or heavily obscured star formation, from the MOSFIRE Deep Evolution Field survey with Hα, Hβ, and [N ii]λ 6585 spectroscopic measurements. We constrain the shape of the attenuation curve by comparing the average flux densities of galaxies sorted into bins of dust obscuration using Balmer decrements, i.e., Hα-to-Hβ luminosities. The average attenuation curve for the high-metallicity sample (

, corresponding to

) has a shallow slope, identical to that of the Calzetti local starburst curve, and a significant UV 2175 Å extinction bump that is ∼0.5× the strength of the Milky Way bump. On the other hand, the average attenuation curve of the low-metallicity sample (

) has a steeper slope similar to that of the SMC curve, only consistent with the Calzetti slope at the 3σ level. The UV bump is not detected in the low-metallicity curve, indicating the relative lack of the small dust grains causing the bump at low metallicities. Furthermore, we find that on average the nebular reddening (E(B − V)) is a factor of 2 times larger than that of the stellar continuum for galaxies with low metallicities, while the nebular and stellar reddening are similar for galaxies with higher metallicities. The latter is likely due to a high surface density of dusty clouds embedding the star-forming regions but also reddening the continuum in the high-metallicity galaxies.
The Contour Method: a New Approach to Finding Modes of Nonadiabatic Stellar Pulsations
Authors: Goldstein J. , Townsend R. H. D.
Published: August 2020

The contour method is a new approach to calculating the nonadiabatic pulsation frequencies of stars. These frequencies can be found by solving for the complex roots of a characteristic equation constructed from the linear nonadiabatic stellar pulsation equations. A complex-root solver requires an initial trial frequency for each nonadiabatic root. A standard method for obtaining initial trial frequencies is to use a star’s adiabatic pulsation frequencies, but this method can fail to converge to nonadiabatic roots, especially as the growth and/or damping rate of the pulsations becomes large. The contour method provides an alternative way to obtain initial trial frequencies that robustly converges to nonadiabatic roots, even for stellar models with extremely nonadiabatic pulsations and thus high growth/damping rates. We describe the contour method implemented in the gyre stellar pulsation code and use it to calculate the nonadiabatic pulsation frequencies of

and

β Cephei star models, and of a

extreme helium star model.
AGN Feedback and Star Formation of Quasar Host Galaxies: Insights from the Molecular Gas
Authors: Shangguan Jinyi , Ho Luis C. , Bauer Franz E. , Wang Ran , Treister Ezequiel
Published: August 2020

Molecular gas serves as a key probe of the complex interplay between black hole accretion and star formation in the host galaxies of active galactic nuclei (AGNs). We use CO(2–1) observations from a new Atacama Large Millimeter/submillimeter Array survey, in conjunction with literature measurements, to investigate the molecular gas properties of a representative sample of 40 z < 0.3 Palomar–Green quasars, the largest and most sensitive study of molecular gas emission to date for nearby quasars. We find that the AGN luminosity correlates with both the CO luminosity and black hole mass, suggesting that AGN activity is loosely coupled to the cold gas reservoir of the host. The observed strong correlation between host galaxy total infrared luminosity and AGN luminosity arises from their common dependence on the molecular gas. We argue that the total infrared luminosity, at least for low-redshift quasars, can be used to derive reliable star formation rates for the host galaxy. The host galaxies of low-redshift quasars have a molecular gas content similar to that of star-forming galaxies of comparable stellar mass. Moreover, they share similar gas kinematics, as evidenced by their CO Tully–Fisher relation and the absence of detectable molecular outflows down to sensitive limits. There is no sign that AGN feedback quenches star formation for the quasars in our sample. On the contrary, the abundant gas supply forms stars prodigiously, at a rate that places most of them above the star-forming main sequence and with an efficiency that rivals that of starburst systems.

Introduction
Authors: Monier Frédéric
Published: August 2020

L’introduction à ce dossier thématique sur la rémunération des élus constate que les enquêtes de première main, reposant sur des sources documentaires, font défaut dans la plupart des pays européens. La question, plus complexe que ce que l’on imagine, éclaire le rapport entre politique et argent, entre rémunération et projets démocratiques. Différentes configurations apparaissent. Dans le cas français, l’indemnité parlementaire créée en 1789, souvent caractérisée comme une norme démocratique, mérite une étude attentive, y compris en scrutant la genèse d’avantages matériels liés au mandat. Par contraste, la situation en Espagne est marquée par la prégnance d’une vision libérale et conservatrice de la fonction de député comme honneur. L’évolution amorcée au tout début du XIXe siècle, ensuite battue en brèche, ne put s’affirmer qu’avec la Deuxième République, après 1931. Enfin, l’étude du cas roumain montre une configuration différente : la rémunération des députés, instituée en 1866, n’y visait ni une plus grande ouverture des formes de sélection du personnel politique, ni la professionnalisation des acteurs. Il s’agissait plutôt d’un ressort financier « systémique ».
La mise en place des fonds de secours et de la caisse des pensions des députés au début du XX e siècle : une prise de conscience d’un changement sociologique ?
Authors: Portalez Christophe
Published: August 2020

Cet article aborde deux dispositifs mis en place au tournant du XXe siècle en faveur des députés : la caisse des pensions des députés et les fonds des secours. La caisse des pensions étant mieux connue de l’historiographie que les fonds de secours, très méconnus voire ignorés. L’auteur interroge ces créations sous l’angle d’un changement de sociologie des députés, qui n’ont plus un patrimoine familial suffisant pour vivre dignement une fois leurs mandats terminés, et présente les débats qui ont pu avoir lieu autour de ces dispositifs en lien avec la question du métier de député. Pour cela il s’appuie notamment sur les archives de la questure de la Chambre, afin d’identifier le fonctionnement de ces dispositifs et leurs bénéficiaires.
La représentation parlementaire comme profession : la rémunération des députés espagnols des Cortès de Cadix à la deuxième République (1812-1933)
Authors: Gemma Rubí Casals Maria , Casals Quintí
Published: August 2020

Dans cet article, les auteurs font une étude préliminaire sur le salaire des députés espagnols à l’époque contemporaine, des Cortes de Cadix à la deuxième République espagnole (1808-1933). Ce travail dans la longue durée permet de connaître l’évolution de la législation et des débats principalement centrés sur la question des incompatibilités. À partir d’une situation initiale dans laquelle les députés des Cortes de Cadix et du triennat libéral (1808-1823) recevaient un per diem pour leur représentation, le système politique libéral censitaire a été adopté, qui a duré jusqu’en 1890, auquel seuls les plus grands contributeurs participaient et dans lequel le poste de député était considéré comme un honneur qui devait être exercé gratuitement. Ce concept a changé avec l’arrivée de la Deuxième République et l’adoption d’un système démocratique universel, qui garantissait les droits politiques de tous les citoyens et la nécessaire rémunération des députés.

Differential Effects of Myeloid Cell PPARδ and IL-10 in Regulating Macrophage Recruitment, Phenotype, and Regeneration following Acute Muscle Injury

Published: August 2020

Changes in macrophage phenotype in injured muscle profoundly influence regeneration. In particular, the shift of macrophages from a proinflammatory (M1 biased) phenotype to a proregenerative (M2 biased) phenotype characterized by expression of CD206 and CD163 is essential for normal repair. According to the current canonical mechanism regulating for M1/M2 phenotype transition, signaling through PPARδ is necessary for obtaining the M2-biased phenotype. Our findings confirm that the murine myeloid cell–targeted deletion of Ppard reduces expression in vitro of genes that are activated in M2-biased macrophages; however, the mutation in mice in vivo increased numbers of CD206+ M2-biased macrophages and did not reduce the expression of phenotypic markers of M2-biased macrophages in regenerating muscle. Nevertheless, the mutation impaired CCL2-mediated chemotaxis of macrophages and slowed revascularization of injured muscle. In contrast, null mutation of IL-10 diminished M2-biased macrophages but produced no defects in muscle revascularization. Our results provide two significant findings. First, they illustrate that mechanisms that regulate macrophage phenotype transitions in vitro are not always predictive of mechanisms that are most important in vivo. Second, they show that mechanisms that regulate macrophage phenotype transitions differ in different in vivo environments.

In this study the effect of the application of High Pressure Treatment (HPP) combined with four different manufacturing processes on the inactivation of Listeria innocua, used as a surrogate for L. monocytogenes, in artificially contaminated coppa samples was evaluated in order to verify the most suitable strategy to meet the Listeria inactivation requirements needed for the exportation of dry-cured meat in the U.S. Fresh anatomical cuts intended for coppa production were supplied by four different delicatessen factories located in Northern Italy. Raw meat underwent experimental contamination with Listeria innocua using a mixture of 5 strains. Surface contamination of the fresh anatomical cuts was carried out by immersion into inoculum containing Listeria spp. The conditions of the HPP treatment were: pressure 593 MPa, time 290 seconds, water treatment temperature 14°C. Listeria innocua was enumerated on surface and deep samples post contamination, resting, ripening and HPP treatment. The results of this study show how the reduction of the microbial load on coppa during the production process did not vary among three companies (P>0.05) ranging from 3.73 to 4.30 log CFU/g, while it was significantly different (P<0.01) for the fourth company (0.92 log CFU/g). HPP treatment resulted in a significant (P<0.01) deep decrease of L.innocua count with values ranging between 1.63-3.54 log CFU/g with no significant differences between companies. Regarding superficial contamination, HPP treatment resulted significant (P<0.01) only in Coppa produced by two companies. The results highlight that there were processes less effective to inhibit the pathogen; in particular for company D an increase of L. innocua count was shown during processing and HPP alone cannot be able to in reaching the Listeria inactivation requirements needed for exportation of dry-cured meat in the U.S. According to the data reported in this paper, HPP treatment increases the ability of the manufacturing process of coppa in reducing Listeria count with the objective of a lethality treatment

Numerous nonmalignant diseases can be treated with radiation therapy (RT). Among them, Heterotopic Ossification (HO) is a benign condition resulting from several causes that can be successfully managed with ionizing radiation. More often seen in the hip area after major surgical procedures, HO is of major concern as it can lead to functional disorders, pain and even to joint ankylosis. We retrospectively analyzed the outcome of therapeutic irradiation for the prevention of HO in 14 patients treated in our hospital between 2005 and 2011. All patients were irradiated with a dose ranging from 7 to10 Gy in a single fraction for prevention of HO after surgery. After a median follow up of 126 months (range 96 – 156 months) none of our patients developed HO. Impaired wound healing or other post surgery complications like trochanteric nonunion were not observed. A single fraction of RT seems to be a sufficient, cost effective and safe treatment regimen. In our study we report excellent results as none of our patients developed HO.
Immediate- and Short-Term Effect of Percutaneous Patent Ductus Arteriosus Closure on Left Ventricular Function: A Speckle Tracking Echocardiographic Study
Authors: Ezzeldin Dina Adel , Wahba Sherif Lotfy , Sayed Maiy Hamdy El , Roushdy Alaa Mahmoud
Published: August 2020

Background:

Patent ductus arteriosus (PDA) closure results in a sudden drop in left ventricular (LV) preload, and this may affect the LV functions.

Aim:

The aim was to evaluate the immediate- and short-term changes in LV functions by speckle tracking echocardiography (STE) post percutaneous PDA closure.

Materials and Methods:

The study included 45 patients with PDA who were referred for PDA trans-catheter closure. All the patients included in the study underwent full echocardiographic examination and speckle tracking analysis before PDA closure, immediately after closure, and 1 month after the PDA closure.

Results:

There was no statistically significant change in LV functions by two-dimensional transthoracic echocardiography; the LV end-diastolic volume (EDV) decreased significantly in the immediate follow-up from 41.608 ± 25.8846 ml before duct closure to 36.317 ± 21.6945 ml. The drop in the LV EDV continued in the 1-month follow-up. The LV end-systolic volume decreased as well, however it took 1 month for this drop to be statistically significant. The LV end-diastolic dimension also decreased significantly after duct closure. Regarding STE results, the global LV strain and strain rate values did not significantly change. The global strain values had a mean of −22.944% ± 3.5128% before duct closure and decreased to a mean −22.028% ± 2.8932% immediately after duct closure.

Conclusion:

The study concluded that STE could be used to detect subtle changes in LV deformation. Time to peak systolic strain is an understudied parameter that needs further evaluation to provide a better understanding regarding its role in myocardial function assessment.
Left Atrial and Renal Functional Status as Drivers of Adverse Outcome in Heart Failure with Reduced Ejection Fraction: A Four-Chamber Deformation Study in a Small Cohort of Northern Sweden
Authors: Saha Samir Kanti , Kiotsekoglou Anatoli , Govind Satish C. , Lindmark Krister
Published: August 2020

In a small cohort of patients (58 ± 12 years) with heart failure and reduced ejection fraction (HFREF), we have analyzed myocardial mechanics in all the four principal cardiac chambers to investigate the prognostic value of left atrial (LA) remodeling. We have also studied to investigate a possible prognostic role of the biochemical markers, such as estimated glomerular filtration rate (eGFR, mL/min/1.73 m2) and N-terminal pro-brain natriuretic peptide (NT-proBNP). We used two-dimensional speckle tracking echocardiography to compute cardiac deformation in addition to measuring LA reservoir strain using two algorithms based on the type of electrocardiogram gating protocol chosen. The data have shown that not only four-chamber strain was significantly lower in HFREF compared with the controls but also LA strain predicted an adverse outcome. In addition, in the subgroup analysis, eGFR was significantly lower in patients with adverse outcome (death or cardiac transplantation). Interestingly, the contribution of the renal biomarker was as significant as NT-proBNP in this regard.

An echocardiographic investigation is one of the key modalities of diagnosis in patients suffering from COVID-19, especially if they are elderly, have associated comorbid conditions, and pregnant. Hence, it is becoming extremely essential to look into the correct safety precautions, health-care professionals must take while conducting an echo investigation. At the same time, a focused echo examination aimed at correct imaging view acquisition in the shortest possible time is the need of the hour. The decision matrix formulated for conducting an echocardiographic evaluation is based on the presence or absence of cardiological comorbidity vis-a-vis positive or suspected for COVID-19. The safety measures and image acquisition have been constructed keeping in mind the current safety precautions by the World Health Organization, the Centers for Disease Control and Prevention, and the Ministry of Health and Family Welfare, India.
Atrioventricular Plane Displacement on Echocardiography in Patients with Left Ventricular Systolic Dysfunction
Authors: Divekar Sagar , Khese Vikrant , Asawa Madhusudan , Phalgune Deepak S. , Chavan Chandrakant
Published: August 2020

Background:

Atrioventricular plane displacement (AVPD) reflects global left ventricular function despite left ventricular asymmetry as it is determined in four different regions of left ventricle. The limitations of agreement between left ventricular ejection fraction (LVEF) and AVPD are not close enough for these two measurements to be interchangeable. There is reason to question whether AVPD provides the same information as LVEF.

Aim:

The aim of this study was to assess relations of AVPD with LVEF and clinical findings in patients left ventricular failure (LVF).

Materials and Methods:

One hundred patients aged ≥18 years with coronary artery disease admitted with LVF were included in this cross sectional study. Echocardiographic examination was performed. Left ventricular AVPD was evaluated by M mode, in the four and two chamber views. Primary aim was to compare AVPD with LVEF by echocardiography. Secondary outcome measures were comparison of AVPD with traditional risk factors, clinical features, and pro-B-type natriuretic peptide (BNP) levels. Comparison of qualitative and quantitative variables was done by using Chi-square test/Fisher's exact test and unpaired t-test. Pearson's correlation was used to study correlation.

Results:

Mean AVPD was significantly lower in patients with severe LVEF as compared to mild, and moderate LVEF. Correlation of AVPD with LVEF, pro BNP, septum, anterior, lateral and posterior wall hypokinesia was 0.895. 0.841, 0.898, 0.911, 0.893 and 0.907 respectively.

Conclusions:

Mean AVPD was significantly lower in patients with severe LVEF. Mean AVPD positively correlated with LVEF, pro BNP, septum, anterior, lateral and posterior wall hypokinesia.

Published: August 2020

Right juxtaposition of atrial appendages are rare and associated with congenital heart defects. We report 3 cases of right juxtaposition of atrial appendages (RJAA) diagnosed by transthoracic echocardiography. The sub-xiphoid sagittal view, parasternal short axis and apical four chambered views demonstrated RJAA. All 3 cases with RJAA were associated with congenital heart disease. Diagnosis was confirmed by CT angiogram and intra-operative findings in two children who underwent surgical correction. Right juxtaposition of atrial appendages is a rare association with congenital heart defects. Transthoracic echocardiographic assessment may give clues to the diagnosis.

Published: August 2020

Este artigo tem como objetivo identificar e analisar o repertório de interação Estado-Sociedade no processo de formulação, negociação, implementação e posterior descontinuidade da política pública de valorização do salário mínimo (PVSM), no período entre 2003 e 2019. O trabalho busca articular contribuições e intersecções teóricas nas áreas da sociologia do trabalho, teoria dos movimentos sociais e ciência política, em especial, a literatura sobre políticas públicas. Utilizou-se como ferramentas metodológicas: a revisão da literatura, análise de documentos e entrevistas com questionário semiestruturado. Em síntese, esse estudo concluiu que o contexto político e sua estrutura de oportunidades políticas são elementos essenciais para determinação das dinâmicas e repertórios de interação entre centrais sindicais e Estado, tanto na transformação do salário mínimo, em um vetor de ação sindical e demanda institucionalizada, quanto no contexto posterior, marcado pelo descumprimento e descontinuidade da PVSM.

“Because They Are Cornish”
Authors: Harasta Jesse
Published: August 2020

Amongst the Cornish people—even many enthusiasts—there has been a long-standing belief that the Kernewek (Cornish) language is useless. Kernewek is a Celtic language spoken primarily by a small cadre of activists in the British region of Cornwall. This paper addresses the difficulties they face when the use of Kernewek in public is seen as legitimate only on the grounds of either economic measures or as static cultural heritage. Drawing upon a data set of almost 70 interviews, this article examines and compares the motivations of language students and one non-user, in the process challenging the notion of “uselessness” and instead focusing on the four ways that its users employ Kernewek in their everyday lives without necessarily utilizing it as a medium of communication. Instead, Kernewek is located within a larger project of social transformation, altering users, their families, the broader ethnic community or the global environment.

Privation of Home Sciences a Skill Based Subject to opt by the Students of Undergraduate Level
Authors: Sadia Farooq  , Mubashra Khalid
Published: August 2020

Home Sciences is an exclusive, professional as well as skill-based subject. In actuality, people are not considering its valuable because of its perception of being joined to home activities. The research determines student, teacher and mother related factors influencing the student to adopt Home Sciences as a subject at undergraduate level. This study is quantitative, in which the data is collected by making three different questionnaires. The first one is filled by the students of Home Sciences at undergraduate level, the second is filled by the teachers who teach undergraduate level and the third questionnaire is filled by the mothers who had studied this subject at any level in their educational career and they have decided to have their girls enrolled in this subject. The analysis is concluded on the percentages which determine the deficits and ideasstated by the three types of respondents. Data results indicate that lack of facilities, finance problems, un-trained teaching staff and a very extensive syllabus make students unwilling to choose this subject even though they know its career opportunities. Teachers do not consider it the most useful subject at undergraduate level but consider it helpful for girls at home. Mothers are agreeable to having more creative teachers for this subject to teach their girls so it can be more useful for them in order to deal with everyday problems.

Published: August 2020

This study investigated the impact of TSA on revenue generation and utilization in the University of Ilorin. Since the implementation of Treasury Single Account (TSA) in 2015 by the present administration in government with the intention to control financial mismanagement which will consequently improve government revenue and economic growth; stakeholders, researchers, and the general public are interested to know the extent to which these objectives have been met. This study empirically examined the extent to which TSA has an effect on total revenue (Grant+IGR) and its utilization. Both the interview and secondary data were utilized for this study. The interview session was for the staff of the Bursary Department of the University. Total fund allocated (Grant+IGR) and its utilization at the University of Ilorin for the period 2012 – 2017 was collected from the Unilorin Annual Reports. The data were divided into two periods: Pre TSA period (2012 to 2014) and Post TSA period (2015 to 2017). A pre-post analysis (difference in means test) was carried out using SPSS version 20. Findings show that the implementation of the Treasury Single Account has improved revenue generation in the University. However, further findings revealed that University’s revenue utilization improved after the implementation of TSA from N6, 691,451,094.41 billion to N8, 928,707,239.14 billion. It was recommended that university administrators, should, as a matter of importance, device other means of boosting their internally generated revenue. This should, however, be done within the ambit of the law.

Authors: Vengadasalam Sarbani Sen
Published: August 2020

There is an urgent need to teach “Writing for Publications” classes to graduate and doctoral students. Though the debate about who should instruct such classes continues, the paper proffers best practices for writing instructors to use while teaching it. The paper highlights the need for scholar-participants to opt for modeling as a way to familiarize themselves with disciplinary and journal conventions. The paper expands on the way online peer review workshops could be conducted at milestone points in the semester to elevate and formalize peer reviews, so integral to the publication process. A sample syllabus with week-by-week activity break-up is offered.
Translator’s Subjectivity in Eco-Translatology
Authors: Jun Wang
Published: August 2020

This paper aims to examine translator’s subjectivity from the perspective of eco translatology. Translator’s subjectivity emphasizes the subjective initiative of translators in the process of translation. However, the identity of translators is invisible in the viewpoints of traditional translation theories, which means that translation is studied with either writer or text as the center. Eco translatology, a new translation theory brought forth by Hu Gengshen, assumes that translators should be placed at the central position during translation practice since translation is actually the cyclical alternation of adaptation and selection in the ecological environment of translation which involves elements such as author, source text, translator, target text, reader, and publisher. According to eco translatology, translators, as the center of translation, are allowed to make selective adaptation and adaptive selection so as to keep the balance and harmony of the ecological environment. Selective adaptation means that translators are supposed to select the text of which they are capable for translation. Adaptive selection means that translators are allowed to make adaptations to the target text based on other factors in the ecological environment of translation. Translator’s subjectivity, namely translator centeredness, is shown in the continuous process of adaptation and selection, and embodied in the three dimensional transformations of language, culture and communication.
Book Review: A Column of Cloud and a Column of Fire: Dimitris Lyacos’ Poena Damni
Authors: Zaller Robert
Published: August 2020

One of the most original and significant texts to have come out of Europe in the past generation is Dimitris Lyacos’ poetictrilogy, Poena Damni. I call it “poetic” because there is no word that quite describes a work that moves alternately betweenpoetry, prose, and drama, and that turns each like a prism in a quest for meaning that yields no final stability but only a“further horizon of pain” (The First Death, Section X).As the above suggests, the text offers us a shifting series of scenes and perspectives, somewhere between a journey and atravail. There is an implicit narrative voice, but no narrative, that shifts abruptly from first to third person, a thread ofconsciousness that weaves in and out of dream and waking, fantasy and vision, confronting us at every turn with that whichboth forces and repels our sight. You know there is a narrative, because something in the voice compels you to continue; yousimply do not know what is being told. You are simply within the framework of a temporality in its most radical sense.Dimitris Lyacos was born in Athens in 1966, and studied law and philosophy. It was conceived back to front, with its“last” part, The First Death, written and published first, and the other segments proceeding backwards toward an origin thatinstates the original wound of the poem’s birth. Lyacos has revised it extensively over the course of some thirty years,retracting an earlier version of what is now With the People From the Bridge that was originally published as Nyctivoe andheavily revising the text called Z213: EXIT. The suggestion, I think, is clear: the poem remains open, a circularity thatdeflects all progression, an ourobouros that never meets its own tail.

STUDY OF BINDING PECULIARITIES OF ETHIDIUM BROMIDE AND METHYLENE BLUE WITH DOUBLE-STRANDED RNA
Authors: Parsadanyan M.A.
Published: August 2020

The paper presents the results of studies on the interaction of intercalators ethidium bromide (EtBr) and methylene blue (MB) with synthetic double-stranded (ds) ribonucleotide ds-poly(rA)-poly(rU) at a solution ionic strengths of 0.02, 0.04 and 0.1 M. These results revealed that poly(rA)-poly(rU) has a relatively unstable structure at the ionic strengths μ$\leq$0.02 M, which leads to the interaction of the mentioned ligands with this polynucleotide. EtBr affinity for ds-poly(rA)-poly(rU) was revealed not to depend on the ionic strength of the solution, while the affinity of MB for this polynucleotide depends on this factor, as well as on the structural state of the polynucleotide.

ETHANOL SUPPLEMENTATION AS A NEW APPROACH TO REGULATE GROWTH AND HYDROGEN PRODUCTION OF $ \textit{ESCHERICHIA COLI} $ UPON GLYCEROL FERMENTATION
Authors: Poladyan A.A.
Published: August 2020

Molecular hydrogen (H2) and ethanol are the main by-products of glycerol fermentation by Escherichia coli. In this study, the growth of E. coli BW25113 was investigated with the addition of small amounts (0.05 to 2 %) of ethanol alone and in a combination with glycerol The bacterial growth, the kinetic of the redox potential, and the H2 production in peptone medium, pH 7.5, were investigated upon various amounts of ethanol supplementation. In the presence of any amount of ethanol, but upon the absence of other sources of carbon, no H2 production was observed. Whereas ethanol (0.3 to 1 %) with a combination of glycerol stimulated both bacterial growth and H2 production, pH 7.5. A correlation was observed between the redox potential and stimulated by ethanol bacterial growth. The obtained results can be applied to regulate fermentation processes in biotechnology.
