FORMATION AND DEVELOPMENT OF THE INTERNAL SYSTEM OF EDUCATION QUALITY ASSURANCE AT THE UNIVERSITY AS A FACTOR OF STATE SOCIO-ECONOMIC DEVELOPMENT
Authors: Artyukhov A.
Published: May 2021

The article is devoted to the description and analysis of factors that potentially and actually affect the socio-economic development of the state on the example of the higher education institution. It is established that at the system level the level of ensuring the quality of educational activities and the quality of higher education has a decisive influence on the formation of a positive image of a higher education institution. The results of a survey of students on the criteria for choosing a university to study are presented.
Statistics on public funding of education in general and higher education in particular are presented and analyzed. It is established that, despite the formally high percentage of education funding from the level of GDP in absolute terms, the actual funding is low and needs to be strengthened by attracting external funding from customers. Attention is also paid to the state of development of educational services for foreign students. In a competitive environment at the national and international level, the decisive influence on the involvement of foreign students in the university is influenced by the structure of the training program, teacher qualifications, organization of the educational process in the classroom and so on.
The article on the example of a higher education institution presents the main stages of formation and development of the internal system of quality assurance of education as an object of influence on the socio-economic development of the state.
The development and/or improvement of internal quality assurance systems in universities is becoming a powerful basis for increasing university funding from external (personally involved) sources, reducing the outflow of applicants abroad and the successful provision of educational services to foreign students. At this stage, given the limited opportunities for funding of educational activities by the state (compared to EU countries), the successful implementation of the university development strategy is possible provided that systematic work is done to improve the quality of educational services for domestic and foreign citizens. As part of further research, it is planned to analyze the mutual impact of the education quality assurance system on the effectiveness of scientific activities, the provision of additional paid educational services, training for external customers and other sources.
ONLINE TRADING DEVELOPMENT IN CONDITIONS OF COVID-19 PANDEMIC CRISIS
Authors: Saher L. , Lazorenko V. , Shevchenko K.
Published: May 2021

The COVID-19 pandemic has had a significant impact on business in Ukraine and around the world. Thus, quarantine has almost stopped a number of industries, including retail (except for food), hotel and restaurant business, air transportation. Due to the introduction of quarantine, domestic enterprises froze investment processes. Most outlets were not ready for the abrupt closure of physical outlets and the inability to sell off-the-shelf products, necessitating a rapid transition to online commerce. Accordingly, it was the pandemic crisis that became the catalyst for e-commerce. However, it should be noted that many companies found it difficult to make a full or partial transition due to lack of experience and understanding of promising ways of development as a subject of the e-commerce market. Accordingly, we can talk about the prospects and the need to study certain issues of e-commerce, in particular in Ukraine. The aim of the work is to identify ways to develop online trade in Ukraine under the influence of the pandemic crisis. The research used methods of comparison, systematization and logical generalization, trend analysis (using Google Trends), bibliometric analysis (using VOSviewer 1.6.16).
The authors conducted a trend analysis, the results of which show a gradual increase in the number of requests by 2018 and a rapid increase since 2019, which is most likely due to a pandemic, when many stores faced problems with product sales. The results of bibliometric analysis show a change in the trend of publishing activity towards the transition from online trading in combination with marketing management, trade marketing tools, consumer behavior analysis to algorithmization and mathematical modeling of consumer behavioral patterns. There is a clear tendency to increase public and scientific interest in this issue. At the same time, the share of domestic publications on this topic is insignificant. Based on the analysis of trends in online trade, the authors proposed promising ways to develop it, identified their advantages, disadvantages and complexity of implementation in Ukraine.

Stationarization and Multithermalization in spin glasses
Authors: Contucci Pierluigi , Corberi Federico , Kurchan Jorge , Mingione Emanuele
Published: May 2021

We develop further the study of a system in contact with a multibath having different temperatures at widely separated timescales. We consider those
systems that do not thermalize in finite times when in contact with an ordinary bath but may do so in contact with a multibath.
Thermodynamic integration is possible, thus allowing one to recover the stationary distribution on the basis of measurements performed in a `multi-reversible' transformation.
We show that following such a protocol the system is at each step described by a generalization of the Boltzmann-Gibbs distribution, that has been studied in the past.
Guerra's bound interpolation scheme for spin-glasses is closely related to this: by translating it into a dynamical setting, we show how it may actually be implemented in practice.
The phase diagram plane of temperature vs ``number of replicas", long studied in spin- glasses, in our approach becomes simply that of the two temperatures the system is in contact with. We suggest that this representation may be used to directly compare phenomenological and mean-field inspired models.
Finally, we show how an approximate out of equilibrium probability distribution may be inferred experimentally on the basis of measurements along an almost reversible transformation.
Triangular Gross-Pitaevskii breathers and Damski-Chandrasekhar shock waves
Authors: Olshanii Maxim , Deshommes Dumesle , Torrents Jordi , Gonchenko Marina , Dunjko Vanja , Astrakharchik G. E.
Published: May 2021

The recently proposed map [5] between the hydrodynamic equations
governing the two-dimensional triangular cold-bosonic breathers [1] and
the high-density zero-temperature triangular free-fermionic clouds, both
trapped harmonically, perfectly explains the former phenomenon but
leaves uninterpreted the nature of the initial
(t=0)
singularity. This singularity is a density discontinuity that leads, in
the bosonic case, to an infinite force at the cloud edge. The map itself
becomes invalid at times
t<0t<0.
A similar singularity appears at
t = T/4t=T/4,
where T
is the period of the harmonic trap, with the Fermi-Bose map becoming
invalid at
t > T/4t>T/4.
Here, we first map—using the scale invariance of the problem—the
trapped motion to an untrapped one. Then we show that in the new
representation, the solution [5] becomes, along a ray in the direction
normal to one of the three edges of the initial cloud, a freely
propagating one-dimensional shock wave of a class proposed by Damski in
[7]. There, for a broad class of initial conditions, the one-dimensional
hydrodynamic equations can be mapped to the inviscid Burgers’ equation,
which is equivalent to a nonlinear transport equation. More
specifically, under the Damski map, the
t=0
singularity of the original problem becomes, verbatim, the initial
condition for the wave catastrophe solution found by Chandrasekhar in
1943 [9]. At
t=T/8t=T/8,
our interpretation ceases to exist: at this instance, all three
effectively one-dimensional shock waves emanating from each of the three
sides of the initial triangle collide at the origin, and the 2D-1D
correspondence between the solution of [5] and the Damski-Chandrasekhar
shock wave becomes invalid.
Non-Wilson-Fisher kinks of $O(N)$ numerical bootstrap: from the deconfined phase transition to a putative new family of CFTs
Authors: He Yin-Chen , Rong Junchen , Su Ning
Published: May 2021

It is well established that the O(N)O(N)
Wilson-Fisher (WF) CFT sits at a kink of the numerical bounds from
bootstrapping four point function of O(N)O(N)
vector. Moving away from the WF kinks, there indeed exists another
family of kinks (dubbed non-WF kinks) on the curve of
O(N)O(N)
numerical bounds. Different from the O(N)O(N)
WF kinks that exist for arbitary NN
in 2<d<42<d<4
dimensions, the non-WF kinks exist in arbitrary dimensions but only for
a large enough N>N_c(d)N>Nc(d)
in a given dimension dd.
In this paper we have achieved a thorough understanding for few special
cases of these non-WF kinks, which already hints interesting physics.
The first case is the O(4)O(4)
bootstrap in 2d, where the non-WF kink turns out to be the
SU(2)_1SU(2)1
Wess-Zumino-Witten (WZW) model, and all the
SU(2)_{k>2}SU(2)k>2
WZW models saturate the numerical bound on the left side of the kink.
This is a mirror version of the Z_2Z2
bootstrap, where the 2d Ising CFT sits at a kink while all the other
minimal models saturating the bound on the right. We further carry out
dimensional continuation of the 2d SU(2)_1SU(2)1
kink towards the 3d SO(5)SO(5)
deconfined phase transition. We find the kink disappears at around
d=2.7d=2.7
dimensions indicating the SO(5)SO(5)
deconfined phase transition is weakly first order. The second
interesting observation is, the O(2)O(2)
bootstrap bound does not show any kink in 2d
(N_c=2Nc=2),
but is surprisingly saturated by the 2d free boson CFT (also called
Luttinger liquid) all the way on the numerical curve. The last case is
the N=\inftyN=∞
limit, where the non-WF kink sits at (\Delta_\phi, \Delta_T)=(d-1, 2d)(Δϕ,ΔT)=(d−1,2d)
in dd
dimensions. We manage to write down its analytical four point function
in arbitrary dimensions, which equals to the subtraction of correlation
functions of a free fermion theory and generalized free theory. An
important feature of this solution is the existence of a full tower of
conserved higher spin current. We speculate that a new family of CFTs
will emerge at non-WF kinks for finite NN,
in a similar fashion as O(N)O(N)
WF CFTs originating from free boson at N=\inftyN=∞.
A diplomás munkavállalók viszonya a változtatásokhoz

Published: May 2021

A tanulmány egy a szervezetek mindennapjait érintő aktuális témát, a szervezeti változtatások hátterét, a diplomás munkavállalók változtatásokhoz fűződő viszonyát tárja fel. A téma komplexitását szem előtt tartva a korábbi tanulmányok és szakirodalom közös metszetében előforduló, meghatározott szempontok alapján, több tudományterületet érintve, az összefüggésekre és a kölcsönhatásokra fókuszálva vizsgáljuk a magyarországi diplomás munkavállalók változtatásokhoz fűződő viszonyát. Az empirikus kutatás, a diplomás munkavállalók változtatásokhoz fűződő viszonyának vizsgálata kérdőíves megkérdezéssel, kvantitatív módszerekkel történt, de a mélyebb összefüggések alaposabb megértése érdekében kvalitatív kutatásra is szükség volt. Hazai szervezetek vezetőivel tizenegy mélyinterjú készült, amelyek a változtatások hatására bekövetkező magatartást, a munkavállalók viselkedésének lehetséges okait és a változtatásokhoz fűződő viszonyukat tárják fel. Megállapításra került, hogy a megkérdezettek változtatásokkal kapcsolatos hozzáállását és együttműködési hajlandóságát leginkább a személyes érintettség és egyéni érdekek, emellett a biztonságvágy, a szocializáció, az egyén személyisége, képességei és jártassága, valamint a feladat milyensége és a szervezethez fűződő bizalom mértéke határozza meg. A vezetők törekvései és támogatása ellenére is nehezen alakul ki a kölcsönös bizalom és összhang a szervezet tagjai között. A munkavállalók egyéni és a szervezet stratégiai céljai közötti diszharmónia miatt a szervezeti célok végrehajtásának elősegítése másodlagos.
A termelői piacok, mint rövid értékesítési láncok marketingkommunikációs kihívásai
Authors: Mészáros Katalin , Németh Nikoletta , Pakainé Kováts Judit
Published: May 2021

A rövid értékesítési láncok közül az egyik leggyakrabban alkalmazott forma a mezőgazdasági termelők és kézművesek számára a termelői piac. Magyarországon az elmúlt években, a kedvező jogszabályi változások következtében, gombamód kezdtek elterjedni a termelői piacok. 2018-ban a Nemzeti Agrárgazdasági Kamara nyilvántartása alapján 292 termelői piacot regisztráltak. A termelői piacok lehetőséget teremtenek az adott város és 40 km-es vonzáskörzetében, kivétel a főváros, gazdálkodók által előállított, de el nem fogyasztott termékek értékesítésére, így a helyi jellegzetességek lakossággal és turistákkal történő megismertetésére is (a fővárosra megengedőbb szabályok vonatkoznak). A termelői piacok kommunikációs tevékenysége a legtöbb esetben ad hoc jellegű, ezért a kutatásunk célkitűzése, hogy feltárjuk az integrált marketingkommunikáció fontosságát. Kutatásunk során Vas megyében 30 helyi termelőt kérdeztünk meg személyes mélyinterjú formájában, a helyi termelői piacok kommunikációs tevékenységével kapcsolatban. A mélyinterjús vizsgálatunk rávilágított arra, hogy a helyi termelői piacok marketingkommunikációs tevékenységében szükséges az egységes arculati elemek kidolgozása, a nyomtatott reklám-, az eladásösztönző-, az esemény- és élménymarketinggel illetve az interaktív marketinggel kapcsolatos eszközök széles körű alkalmazása, valamint a hagyományos szájreklám.
Detailed Description on the Three Dimensions of Deprivation
Authors: Ünal Hakan , Obádovics Csilla , Bruder Emese
Published: May 2021

This study introduces a method for measuring standard of living, based on a three-dimensional model. The authors argue that their proposed indicators (and items) can more realistically capture people’s inability to afford an adequate way of living than the ones Eurostat uses and recommends. The commonly used deprivation measuring method has a unidimensional perspective and provides only a general overview of those living in deprivation. The authors’ multidimensional approach, however, considers not only the well-known aspects of human life but also others, giving a more extensive view of individuals’ needs. The calculations are based on the European Union Statistics on Income and Living Conditions database provided by Eurostat and the relevant Turkish data­base from the Turkish Statistical Office. The decomposite method introduced in the study measures standard of living using three dimensions, economic strain, living conditions, and housing and environmental conditions.
Augmentation Therapy with Alpha-1 Antitrypsin: Present and Future
of Production, Formulation, and Delivery
Authors: Bianchera Annalisa , Alomari Esraa , Bruno Stefano
Published: May 2021

Alpha 1-antitrypsin is one of the first protein therapeutics introduced on the market more
than 30 years ago, and to date, it is indicated only for the treatment of the severe forms of a genetic
condition known as alpha-1 antitrypsin deficiency. The only approved preparations are derived
from plasma, posing potential problems associated with its limited supply and high processing
costs. Moreover, augmentation therapy with alpha-1 antitrypsin is still limited to intravenous infusions,
a cumbersome regimen for patients. Here, we review the recent literature on its possible future
developments, focusing on i) the recombinant alternatives to the plasma-derived protein, ii)
novel formulations, and iii) novel administration routes. Regulatory issues and the still unclear
noncanonical functions of alpha-1 antitrypsin, possibly associated with the glycosylation pattern
found only in the plasma-derived protein, have hindered the introduction of new products. However,
potentially new therapeutic indications other than the treatment of alpha-1 antitrypsin deficiency
might open the way to new sources and new formulations.
Restoration of Chemoresistance Mechanism by Novel Drug Therapies in Breast Cancer Cell Lines
Authors: Sarkar Esha , Misra Aparna , Mahdi Abbas Ali , Trivedi Anchal , Khan Afreen
Published: May 2021

Chemoresistance is one of the biggest hurdles while treating cancer clinically. Due to its
heterogeneous nature, complications of the chemoresistance mechanisms of breast cancer cannot
be completely elucidated. Existing mechanisms of main-line drug treatment can slow down the process
of malignancy with part and parcel called drug resistance. The combinatorial effect of several
chemotherapeutic drugs, targeting different pathways at the same time, can work efficiently, yet
the toxicity and drug-drug interaction remain intact.

To overcome this hurdle, a number of strategies have been discovered, such as novel agents, drug
carriers, and combination treatment, etc., which target mediated drug delivery systems; nanomedicine
and the use of phytocompounds can transfer the drug particularly to the cancerous cells
with minimal side effects to the neighboring healthy cells. The cell cycle checkpoint proteins and
genes induced to the deranged cells can inhibit the resistance mechanism towards the drug. Modification
of cell signaling pathways can also help to treat breast cancer chemoresistance mechanisms
in the long run. This article reviews the execution and onset of chemoresistance in various cancers
and discusses potential therapeutic approaches to deal with the resistance mechanism.

This review summarizes the possible mechanisms and signaling pathways causing chemoresistance
in breast cancer cell lines and discusses alternative therapy to overcome this issue under pre-clinical
and clinical infrastructure.
Neuroregenerative Activity of the Dipeptide Mimetic of Brain-derived Neurotrophic Factor GSB-106 Under Experimental Ischemic Stroke
Authors: Gudasheva Tatiana A. , Povarnina Polina Y. , Antipova Tatiana A. , Kruglov Sergey V. , Logvinov Ilya O. , Nikiforov Dmitry M. , Seredenin Sergey B.
Published: May 2021

Background:

A dimeric dipeptide mimetic of the BDNF loop 4, bis(N-monosuccinyl-
L-seryl-L-lysine) hexamethylenediamide (GSB-106) activates TrkB, PI3K/AKT, MAPK/
ERK, and PLC-γ1, and was created at the V.V. Zakusov Research Institute of Pharmacology.
GSB-106 showed neuroprotective activity in vitro and in vivo at systemic administration.

Objective:

In this work, we studied the GSB-106 effect on the cerebral infarct volume, as well as
on neurogenesis and synaptogenesis under the experimental ischemic stroke induced by intravascular
occlusion of the middle cerebral artery in rats.

Methods:

GSB-106 was administered i.p. in a dose of 0.1 mg/kg, 24 h after the surgery and then
once a day, with the end of administration on day 6 after surgery. On day 7, brain samples were collected
for morphometric and biochemical (Western-blot) analysis.

Results:

It was established that GSB-106 reduced the brain damage volume by 24%, restored impaired
neurogenesis and/or gliogenesis (by Ki-67) in the hippocampus and the striatum, and completely
restored the reduced immunoreactivity to synaptic markers synaptophysin and PSD-95 in
the striatum.

Conclusions:

Thus, the dimer dipeptide BDNF mimetic GSB-106 exhibits neuroregenerative properties
at a clinically relevant time window (24 h) in a model of ischemic stroke presumably due to
the stimulation of neurogenesis (and/or gliogenesis) and synaptogenesis.
Kinetic Study of Iodination of Propanone in Different Acidic
Media by Using Colorimeter
Authors: Kumar Ashok , Sharma Nitin , Alam Tanveer
Published: May 2021

Aims:

Kinetic study of iodination of propanone in different acidic medium by using
colorimeter.

Background:

The kinetic experimentation of iodination of propanone has been done in
presence of different acid such as sulphuric acid, hydrochloric acid and acetic acid. The rate
law of the iodination of propanone in acidic medium is determined by observing the disappearance
of the brownish yellow colour of iodine in aqueous solution.

Objective:

Preparation of standard solution, Determination of absorbance of iodine solution
at λmax= 480 nm, Kinetic study of iodination of propanone at different acidic medium.

Method:

The kinetic analysis of this reaction has been investigated by colorimetry. The extent
of the reaction has been monitored by measuring the absorbance of reaction mixture after
a suitable time interval.

Result:

The rate law expression has been determined to be rate = k [propanone]0
0.728 [acid]
0. The rate of iodination of propanone in the presence of different acidic medium is in the
order of H2SO4 > HCl > CH3COOH.

Conclusion:

The rate of the reaction has been found to be independent of the concentration
of iodine, i.e., a zero-order reaction with respect to iodine; however, it depended upon the
concentration of propanone and the acidic catalyst. In this experimental technique, the consumption
of chemicals is minimal.
Sources of Active Ingredients for Sustainable Corrosion Inhibitors
Authors: Sharma R.
Published: May 2021

Metal corrosion is a grave problem, having deleterious effects on human health, the economy, the environment, and many engineering schemes, for example, automobiles, aircraft, naval vessels, and pipelines. For the confirmation of enduring reliability and stability of alloys and metals, corrosion-protective surfaces are of the greatest significance, for example, ions and water, through restraining their interactions with corrosive species. Though, their applied submissions are frequently bounded whichever through deprived mechanical robustness or else through the incapability to resist low surface tension liquids, for example, alcohols and oil. In this chapter, we have focused on diverse materials as sustainable corrosion inhibitors such as organic corrosion inhibitors, green corrosion inhibitors, and polymer-based corrosion inhibitors to protect materials from being corroded. Amongst them, we especially focus on green corrosion inhibitors as a consequence of simple manufacturing, easy availability, cost-effectiveness, and biodegradable nature.
Green Corrosion Inhibitors from Biomass and Natural Sources

Published: May 2021

Considering the fact that corrosion of metals and alloys presents a significant problem all over the world, the one of most recently utilized approaches to combat this problem necessitates the researches for employment of new materials, which satisfied the green chemistry idea. In this connection, the development of sustainable corrosion inhibitors is highly demanded due to the increasing of awareness of green chemistry principles not only in corrosion discipline, but also in all branches of science and technology. Due to natural and biological origin as well as their eco-friendly extraction, the plant materials and biomass derived from various waste sources could be applied as beneficial substances for metals and alloys protection in different corrosion environment. Therefore, this work reports the main findings regarding their employments as green anticorrosion substances.
The Disclosure of Personally Identifiable Information in Studies of Neighborhood Contexts and Patient Outcomes (Preprint)

Published: May 2021

UNSTRUCTURED

Clinical epidemiology and patient-oriented health care research that incorporates neighborhood-level data is becoming increasingly common. A key step in conducting this research is converting patient address data to longitude and latitude data, a process known as geocoding. Several commonly used approaches to geocoding (eg, ggmap or the tidygeocoder R package) send patient addresses over the internet to web-based third-party geocoding services. Here, we describe how these approaches to geocoding disclose patients’ personally identifiable information (PII) and how the subsequent publication of the research findings discloses the same patients’ protected health information (PHI). We explain how these disclosures can occur and recommend strategies to maintain patient privacy when studying neighborhood effects on patient outcomes.

Published: May 2021

Este artigo procurou analisar as condições do desenvolvimento sustentável de 78 municípios de Mato Grosso do Sul com variáveis agregadas em três dimensões: ambiental, social e econômica. O objetivo foi calcular o índice de desenvolvimento sustentável municipal (IDSM) nos três anos censitários (1991, 2000 e 2010) e, com isso, analisar se as localidades cresceram de forma sustentável ou não. Utilizando o método de análise envoltória de dados (DEA), inicialmente, foi calculado um modelo DEA com retornos variáveis de escala (VRS) para cada dimensão e cada ano e, após isso, o cálculo do indicador global de sustentabilidade. Os resultados apontaram que, embora os municípios tenham registrado melhora no desenvolvimento econômico e social, a dimensão ambiental registrou diminuição entre os anos de 2000 a 2010, mesmo tendo evoluído positivamente entre 1991 e 2000. Os valores médios dos IDSM’s nos anos de 1991, 2000 e 2010, de 0,55, 0,74 e 0,58, respectivamente.

Published: May 2021

Background and objectives

Dialysis facilities in the United States play a key role in access to kidney transplantation. Previous studies reported that patients treated at for-profit facilities are less likely to be waitlisted and receive a transplant, but their effect on early steps in the transplant process is unknown. The study’s objective was to determine the association between dialysis facility profit status and critical steps in the transplantation process in Georgia, North Carolina, and South Carolina.

Design, setting, participants, & measurements

In this retrospective cohort study, we linked referral and evaluation data from all nine transplant centers in the Southeast with United States Renal Data System surveillance data. The cohort study included 33,651 patients with kidney failure initiating dialysis from January 1, 2012 to August 31, 2016. Patients were censored for event (date of referral, evaluation, or waitlisting), death, or end of study (August 31, 2017 for referral and March 1, 2018 for evaluation and waitlisting). The primary exposure was dialysis facility profit status: for profit versus nonprofit. The primary outcome was referral for evaluation at a transplant center after dialysis initiation. Secondary outcomes were start of evaluation at a transplant center after referral and waitlisting.

Results

Of the 33,651 patients with incident kidney failure, most received dialysis treatment at a for-profit facility (85%). For-profit (versus nonprofit) facilities had a lower cumulative incidence difference for referral within 1 year of dialysis (−4.5%; 95% confidence interval, −6.0% to −3.2%). In adjusted analyses, for-profit versus nonprofit facilities had lower referral (hazard ratio, 0.84; 95% confidence interval, 0.80 to 0.88). Start of evaluation within 6 months of referral (−1.0%; 95% confidence interval, −3.1% to 1.3%) and waitlisting within 6 months of evaluation (1.0%; 95% confidence interval, −1.2 to 3.3) did not meaningfully differ between groups.

Conclusions

Findings suggest lower access to referral among patients dialyzing in for-profit facilities in the Southeast United States, but no difference in starting the evaluation and waitlisting by facility profit status.
Атомно-силовая микроскопия: изучение вирусов

Published: May 2021

Вирусы – это объекты природы размером в десятки-сотни нанометров. Они часто состоят из молекул всего лишь двух типов: нуклеиновой кислоты, ДНК или РНК и белков. Иногда добавляются и липиды. Вирусы не могут самостоятельно размножаться, как, например, бактерии. Репликацию вирусов проводит сама инфицированная клетка, для чего она нарабатывает много копий нуклеиновых кислот и белков. В статье мы рассмотрим в деталях с помощью атомно-силового микроскопа различные виды вирусов, увидим их структурные особенности, которые делают их неуязвимыми, и узнаем, может ли одна вирусная частица вызвать заболевание.

İnsanın tarihsel serüveninden günümüze değin doğa, çeşitli değişimlere girerek insan üzerinde etkisini göstermiştir. Doğanın tüm yıkıcı unsurlarına karşı, insan beceri ve düşünme potansiyelini geliştirdikçe, doğayı tanımaya başlamış ve kendine faydalı olabilecek tüm kaynakları elde etme yeteneğini geliştirmiştir. Tarihsel olarak insanoğlunun doğa ile olan ilişkisi, özellikle Aydınlanma ve 19. yüzyıl sonrasında gelen endüstriyel gelişmeler ile birlikte kopma noktasına gelmiştir. Sanayileşme ve teknolojinin yarattığı aşırı tüketimle birlikte, zehirli salınımlar toprak, hava ve su kirliliğine, iklim değişikliğine, çölleşme ile beraber göç hareketlerine ve biyolojik çeşitliliğin azalması gibi değişikliklere neden olmuştur. Bu olumsuz etkilerin sonucunda “Ekoloji Bilimi”, hem büyük bir önem hem de küresel kapitalizmin sosyal dengeleri etkilemesinden dolayı politik bir boyut kazanmıştır. 1960 sonrası iklim değişiklikleri başta olmak üzere çevre sorunlarının artmaya başlamasıyla birlikte ortaya çıkan ekolojik bilinç, insanın yalnızca doğaya dönmesi ile kalmamış bu durum sanat ve sanatçı üzerinde de etkisini göstermiştir. Doğanın tahribatına karşı sanatçılar doğayı yaşanır kılmak ve sanat aracılığıyla yeniden insanın doğayı keşfetmesini sağlamak için ekoloji temalı işler üretmeye başlamışlardır. Ekoloji temalı bu işler “Ekolojik Sanat” olarak da nitelendirilen sanatın temel dinamiklerini oluşturmuştur.

Published: May 2021

In late 2019 and early 2020, governments around the world closed educational institutions due to the COVID-19 pandemic. A similar response occurred in Canada and resulted in a sudden pivot by teachers from classroom-based instruction to remote teaching. During and shortly after this time, we undertook a survey study of over 2000 Canadian teachers, as well as follow-up interviews with a representative sub-set of those who took part in the initial round of the survey, to gain perspectives on teaching during the pandemic crisis. We summarize the foundations of the entire study and focus on the analysis and discussion of interview data to provide enhanced understanding of initial survey results. This study presents five lessons from the voices of teachers in the initial stages of COVID-19 in Canadian K-12 schools. Each lesson addresses a reality of teaching that was magnified by the pandemic and is highlighted for future consideration of educators in times of uncertainty and change.

LEITURA FÍLMICA: UMA ANÁLISE DISCURSIVA DOS EFEITOS DE SENTIDO DE TEMAS ABORDADOS EM DESENHO ANIMADO DA TURMA DA MÃ”NICA
Authors: Braga Sandro
Published: May 2021

Apresentamos uma discussão acerca da leitura em sala de aula. Entendemos a leitura como uma prática para além da materialidade da escrita. A partir do escopo da Análise do Discurso de inspiração francesa, investimos na perspectiva de que ler é interagir. Para isso, é necessário saber ler o mundo, interpretá-lo e, por fim, reescreve- lo. Assim, propomos a leitura de filmes da Turma da Mônica como instrumentalização para outros processos de leitura do mundo atual, que é permeado de imagem e som. Nosso foco está na formação de leitores críticos, capazes de percorrer as tramas discursivas que levam um texto a produzir sentido.

The preparation of hydrogen by photocatalytic principle is an important
subject in the future energy direction. This article intends to design
the catalytic structure of a crystalline (amorphous)
TiO2/two-dimensional MoS2 sandwich structure supporting a single-atom,
and explore the effect of this special structure on the photocatalytic
reaction.Calculating the effective mass, electrostatic potential, light
absorption spectrum and other related properties by DFT method, the
analysis shows that the sandwich structure catalyst has good carrier
transfer ability and electron-hole separation ability. Except for the
Pt@Amorphousr-TiO2/MoS2 sandwich structure single-atom catalyst, which
only has an excellent effect on the oxygen evolution of water, the rest
of the interlayer catalysts have the two characteristics of
photocatalytic hydrogen evolution and oxygen evolution.The new catalyst
designed in this paper has innovative design ideas and high-efficiency
research and development value.
Structure and Hydrogen Bonds of Hydrophobic Deep Eutectic Solvent-Aqueous Liquid-Liquid Interfaces
Authors: Abbas Usman , Qiao Qi , Nguyen Manh Tien , Shi Jian , Shao Qing
Published: May 2021

Hydrophobic deep eutectic solvents (DESs) emerge as candidates to
extract organic substrates from aqueous solutions. The DES-aqueous
liquid-liquid interface plays a vital role in the extraction ability of
hydrophobic DES because the non-bulk structure of molecules at the
interface could cause thermodynamic and kinetic barriers. One question
is how the DES compositions affect the structural features of the
DES-aqueous liquid-liquid interface. We investigate the density profile,
dipole moment and hydrogen bonds of eight hydrophobic DES-aqueous
liquid-liquid interfaces using molecular dynamics simulations. The eight
DESs are composed of four organic compounds: decanoic acid, menthol,
thymol, and lidocaine. The simulation results show the variations of
dipole moment and hydrogen bond structure and dynamics at the
liquid-liquid interfaces. Such variations could influence the extraction
ability of DES through adjusting the partition and kinetics of organic
substrates in the DES-aqueous biphasic systems.
Methyl Iodide Adsorption on Reduced Silver-Functionalized Silica Aerogel: How Temperature Impacts the Adsorption?
Authors: Tang Siqi , Choi Seungrag , Tavlarides Lawrence
Published: May 2021

To understand the effect of temperature to the adsorption, 104 ppbv and
1044 ppbv methyl iodide (CHI) adsorptions on reduced
silver-functionalized silica aerogel (Ag-Aerogel) at
100, 150 and 200 ℃ were performed. In the experiments, a significantly
high uptake rate (3 – 4 times higher than that at 100 and 150 ℃) was
observed for the 104 ppbv adsorption at 200 ℃. To explain such behavior,
a potential reaction pathway was proposed and multiple physical analyses
including nitrogen titration, x-ray photoelectron spectroscopy (XPS) and
scanning electron microscopy (SEM) were performed. Based on the results,
the contributing factors appear to be the formation of different Ag-I
components induced by temperature, higher silver site availability,
decreasing diffusion limitation, and increasing reaction rate described
by the Arrhenius relationship.
