Karyotype evolution of the genus Eranthis Salisb. (Ranunculaceae)
Authors: Mitrenina E. Yu , Erst A. S.
Published: September 2021

We have conducted comparative study of karyotypes for nine Eranthis Salisb. species: E. bulgarica (Stef.)Stef., E. hyemalis (L.) Salisb., E. longistipitata Regel (section Eranthis), E. byunsanensis B. Y. Sun, E. lobulata W. T.Wang, E. pinnatifida Maxim., E. sibirica DC., E. stellata Maxim., and E. tanhoensis Erst (section Shibateranthis). Thespecies-specifity of karyotypes was established for all species investigated. The chromosomes of each species weremedium or large in size (4–12 µm). Besides E. sibirica and E. tanhoensis, all the investigated specimens had diploidcytotypes with 2n = 16 and the basic chromosome number x = 8. Plants from five E. sibirica populations were tetraploidand hexaploid with x = 7, 2n = 28 and 2n = 42 respectively. Plants from seven E. tanhoensis populations were diploid withx = 7 and 2n = 14. Diploid karyotypes of Eranthis included 4–5 pairs of large equal-armed (metacentric) chromosomes,and 2–4 pairs of unequal-armed chromosomes belonging to different morphological types (submetacentric, subtelocentric,and acrocentric ones). We have revealed B chromosomes in root meristematic cells of E. lobulata and E. tanhoensis forthe first time. We suppose that the key developments in Eranthis karyotype`s evolution were pericentric inversions,polyploidy, and probably translocations.

Authors: Iurmanov А. А. , Romanov M. S. , Bobrov A. V.
Published: September 2021

The oldest representatives of Cymodoceaceae supposedly arose in the tropical waters of East Gondwana inCretaceous and later settled along the World Ocean by various tracks, the most important of which passed along the southern coast of Eurasian continental masses and reached the waters of modern Atlantic. More advanced genera Cymodocea,Syringodium originated in these areas and moved “back” to the waters of the Indian Ocean and the southwestern Pacific.

Authors: Osmonali B. B. , Akhtaeva N. Z. , Vesselova P. V. , Kudabayeva G. M. , Kurbatova N. V.
Published: September 2021

The features of the anatomical structure of Salsola arbuscula Pall., S. tragus L., S. paulsenii Litv. are presented. It is noted that the leaf blades of the studied species belong to the salsoloid type. The mesophyll of the leaf is centric. The hypoderma plays the role of the water-bearing parenchyma. In the water-bearing parenchyma of S. tragus and S.paulsenii calcium oxalate crystals have been found. In the central part of the leaf there is a single conducting beam of thecollateral type in all species. A characteristic feature in the anatomical study of the stem of S. tragus is the peculiarity ofthe collenchyma, which lies only in the area of protrusions and forms up to 7 layers of cells. The general features of theorganization of the studied species are the similarity in the succulent structure of the leaf blade, which causes large-cellwater-bearing parenchyma and the rounded shape of the cells in the three studied species of saltwort.

Authors: Aristarkhova E. A. , Suslova E. G.
Published: September 2021

The article analyzes the ecology and distribution of species of genera: Bryoria Brodo et D. Hawksw., Ramalina Ach., Usnea Dill. ex Adans., found in Moscow region and listed in the red book of the region (2018). It is based onliterature materials and monitoring data that we conducted as part of the «Verkhovye» Nature protection Fund in 2010–2019.In the period from 1906 to 1995, a greater number of Ramalina species were cited for Moscow region than at present,some of the finds of Usnea species were made on the outskirts of Moscow and in the near Moscow region, meanwhile thedistribution of genus Bryoria was not studied. Currently, the most favorable conditions for the development of lichens areformed in the North, West and North-West of the Moscow region, where the largest number of finds of various specieswith maximum abundance is noted. In the South-east, their settlement is probably hindered by dust, increased dryness ofthe air and the presence of harmful compounds in the atmosphere. In their distribution, lichens prefer intact habitats withhigh humidity and minimal air pollution: large fragments of preserved protected old-growth forests (spruce and sprucesmall-leaved), swampy forests and forest swamps.For the most common species with a high abundance (Bryoria fuscescens (Gyeln.) Brodo et D. Hawksw. и B. capillaris (Ach.) Brodo et D. Hawksw., Usnea hirta (L.) Weber ex F. H. Wigg.и др.), it is possible to track the dynamics ofchanges in the environment. The rarest species are recommended to keep category 1–2 in the Red book of the Moscow region (Bryoria nadvornikiana (Gyeln.) Brodo et D. Hawksw., B. vrangiana (Gyeln.) Brodo et D. Hawksw., B. osteola(Gyeln.) Brodo et D. Hawksw., Usnea lapponica Vain. и др.).

A Study of the Structure, Organization, Genome, Life cycle, Pathogenicity and Vaccines of the Influenza A virus
Authors: Sahoo Sankalpa
Published: September 2021

SahooInfluenza A virus (IAV) is a well-known human respiratory pathogen of the family Orthomyxoviridae. Though infection is primarily considered to be limited only to the respiratory system where it can cause very severe pulmonary problems and ultimately can lead to death, extrapulmonary complications such as myocarditis and encephalitis have also been observed. As IAV targets various hosts, including human, swine, avian, equine and poultry, the emergence of novel strains is highly expected, which generates a constant threat of the emergence of unpredictable pandemics.

Authors:   International Burch University, Odak Mario , Sijercic Adna ,   International Burch University
Published: September 2021

– Homeschooling is a term typically used to describe the form of education where parents educate their own children at home with little to no contact with public school education. The purpose of this study is to gather information on the public opinion of homeschooling in Sarajevo Canton, Bosnia and Herzegovina, as well as to see how the COVID-19 pandemics affected this opinion. For this purpose, a survey was conducted and, as a result, information on the topic is gathered. The general opinion of the public leaned more towards the negative end when all the results were summarized. Homeschooling, in general, is not a term that people are familiar with and accepting of in t h e region of Sarajevo Canton, Bosnia and Herzegovina. Additionally, the COVID-19 pandemic has not had a positive influence on the opinion of the homeschooling.
Covid-19: were curfews in France associated with hospitalisations?
Authors: Le Bourg Eric
Published: September 2021

Objectives

A curfew was introduced in France in October 2020 to reduce the spread of Covid-19. This was done for two weeks in 16 departments, or for one week in 38 others, 42 departments not being subjected to the curfew. This article compares the number of new daily hospital admissions in these departments.

Methods

The ratio of the number of new hospitalisations during these two weeks and in the previous two weeks was computed in the three categories of departments.

Results

The increase in new hospitalisations was lower in departments under curfew for two weeks than in all other departments, and this result does not seem to be linked to characteristics of the departments before curfew.

Conclusions

This result shows that the two-week curfew is linked to a lower increase of hospitalisations, but not that the curfew by itself is the cause of this result, as other factors may have played a role.
Stable super-hydrophobic and comfort PDMS-coated polyester fabric
Authors: Xu Liyun , Xie Kaifang , Liu Yuegang , Zhang Chengjiao
Published: September 2021

Super-hydrophobic fabrics have shown great potential during the last decade owing to their novel functions and enormous potential for diver’s applications. Surface textures and low surface energy coatings are the keys to high water repellency. However, the toxicity of nanomaterials, long perfluorinated side-chain polymers, and the fragile of micro/nano-texture lead to the super-hydrophobic surfaces are confined to small-scale uses. Thus, in this article, a stable polydimethylsiloxane (PDMS)-coated super-hydrophobic poly(ethylene terephthalate) (PET) fabric (PDMS-g-PET) is manufactured via dip-plasma crosslinking without changing the wearing comfort. Benefiting from the special wrinkled structure of PDMS film, the coating is durable enough against physical abrasion and repeated washing damage, which is suffered from 100 cycles of washing or 500 abrasion cycles, and the water contact angle is still above 150°. This study promotes the way for the development of environmentally friendly, safe, and cost-efficient for designing durable superhydrophobic coatings for various practical applications.
Social Entrepreneurship and Volunteering: Moderation Effects of Volunteer Experience Levels on Social Entrepreneurial Intent Model

Published: September 2021

This study investigates whether an individual’s social work experience impacts the relationship between institutional environmental constructs and the perceived desirability and feasibility of establishing a social venture. It extends Urban, B. and L. Kujinga’s. (2017. “The Institutional Environment and Social Entrepreneurship Intentions.” International Journal of Entrepreneurial Behaviour and Research 23 (4): 638–55, doi: 10.1108/IJEBR-07-2016-0218.) social entrepreneurial intent model by comparing two groups of volunteers in Malaysia with different levels of social working or volunteering experience. The results show that the cognitive environment influences perceived desirability, with a distinctly higher path significance for perceived desirability among individuals with higher levels of experience. Perceived desirability has a relatively more substantial impact on social entrepreneurship intention for highly experienced individuals. Interestingly, the results indicate that neither the regulatory nor the normative environment influences perceived feasibility for either group. Governments and other relevant organisations can utilise these findings to devise better policies for promoting social entrepreneurship.
Role of magnetic resonance diffusion weighted imaging in diagnosis of diabetic nephropathy in children living with type 1 diabetes mellitus
Authors: Wahba Eman Nabil , Elsharkawy Ashraf , Awad Mohammad Hosny , Abdel Rahman Ashraf , Sarhan Amr
Published: September 2021

Objectives

Diabetic nephropathy is a serious and a common complication of diabetes that can lead to end stage renal disease among children living with type 1 diabetes, thus an early and accurate method of diagnosis that allows timely intervention is of high importance. This study aimed to evaluate the role of magnetic resonance diffusion weighted imaging in diagnosis of diabetic nephropathy in children with type 1 diabetes.

Methods

This prospective, observational, case control study included 30 children with type 1 diabetes and 30 matched healthy controls attending the outpatient clinics in Mansoura University Children’s Hospital. All were subjected to magnetic resonance DWI of the renal parenchyma and their glomerular filtration rate (GFR) was estimated, along with micro albumin in 24 h urine collection and HbA1c in patients with diabetes.

Results

Children with diabetes who were positive for microalbuminuria had significantly lower apparent diffusion coefficient value compared to Children with diabetes who were negative for microalbuminuria (p = 0.034) as well as controls (p = 0.001). Among children with type 1 diabetes, apparent diffusion coefficient had significant positive correlation with estimated glomerular filtration rate (r = 0.491, p = 0.006) and negative correlation with microalbuminuria (r = −0.437, p = 0.016).

Conclusion

Magnetic resonance DWI of the renal parenchyma is correlated with estimated glomerular filtration rate (eGFR) in children with type 1 diabetes and can detect GFR deterioration even in presence of normal albumin excretion.

Prolegomenon
Authors: McHugh Kathleen
Published: September 2021

Kathleen McHugh explores the complex functions of women’s anger in the work and aesthetic circuitry—culture, texts, audience, reviewers—of contemporary feminist filmmakers. For all its ubiquity as a feminist feeling, anger has been little considered critically. While 1970s white theorists of feminine/feminist film aesthetics did not mention anger, feminist lesbian, materialist, and women-of-color critics lamented its absence. Julie Dash’s 1982 Illusions inaugurated an aesthetics of anger from a Black feminist perspective that exemplified the ideas in Audre Lorde’s foundational 1981 essay, “The Uses of Anger.” Drawing from Lorde’s and Sara Ahmed’s ideas about the creative value of feminist anger, together with recent affect theory on “reparative reading” and “better stories,” the essay explores four contemporary directors’ films and media works for how anger shapes their texts and critical reception and cultivates a mode of affective witness in their audiences.
Black Obliteration around the Corner
Authors: Wanzo Rebecca
Published: September 2021

FQ columnist Rebecca Wanzo examines the new genre of “gentrification” films and documentaries that has emerged during the first two decades of the 21st century. Gentrification documentaries, such as Laura Poitras and Linda Goode Bryant’s Flag Wars (2003), tend to highlight not only displacement but the effects arising from class disparities that have become hypervisible with the proximity of new, affluent residents. In fictional films, however, gentrification has been a new iteration of what Paula Massood has characterized as “Black city cinema”—films in which migration and “visual and aural iconography” play a role in defining Black bodies in city spaces. Wanzo argues that the ephemerality and ambivalence arising from the displacement produced by gentrification is perhaps best exhibited by two recent fictional films: The Last Black Man in San Francisco (Joe Talbot, 2019) and Residue (Merawi Gerima, 2020). These elegiac works explore how gentrification eliminates spaces for Black men to inhabit.
The Present and Future Dystopias of Nuevo orden and Medida provisória
Authors: Betancourt Manuel
Published: September 2021

FQ columnist Manuel Betancourt identifies an uncanny trend in recent Latin American cinema: the depiction of future dystopias that, despite subtle sci-fi touches, feel more than ever like tweaked visions of already harrowing presents. His column focuses on two new films that exemplify the power such a genre holds on the region’s cultural imagination: Michel Franco’s Nuevo orden (New Order, 2020) and Lázaro Ramos’s Medida provisória (Executive Order, 2020). Both films feel much ripped from the headlines, a timely response to years of unrest and decades (if not centuries) of racist governance. Betancourt warns that such speculative attempts should be approached with both caution and optimism. A dystopian film need not function solely as a funhouse mirror but can also be a window into a new paradigm, with sci-fi touches offered as potential tools to illuminate ways to carve newer, better futures.

Institutional Influence of Academics in Argentinean Public Universities in a Context of External Control
Authors: Marquina Mónica , Pérez Centeno Cristian , Reznik Nicolás
Published: September 2021

The paper studies the institutional influence of academics in Argentina within a context of increasing external control as a consequence of deep public reforms in the Higher Education system. Drawing on data from the Academic Profession in the Knowledge-Based Society (APIKS) survey, the aim is to analyse how much and in what sense the recent changes on the public policy level and the intermediate level of the state agencies have affected the academic profession in Argentina over teaching, research and social engagement activities, and its effects over the perception of institutional influence. Although we assume that academic power has been reduced within the new scenario, we believe that not all academics have responded in the same manner.
Social drama of independence
Authors: Proleiev Sergii
Published: September 2021

The article analyzes the problem of Ukraine's development since independence. A comparison of the way of organizing social reality in modern Ukraine and in the Soviet period is carried out. The main regulatory factor in the life of Soviet society was the principle of domination. Ukraine has inherited the principle of domination and retains its leading role in the current social order. Its various manifestations that determine the structure of Ukrainian society, in particular the growth of the bureaucratic class and bureaucratic pressure on all spheres and sections of life, are analyzed. The dominance of bureaucracy contains latent violence, feeds corruption and minimizes social dynamics. It is also a phenomenon of power rent, which finds its expression in a kind of "privatization of the state." Another universal effect of the principle of domination is the doubling of social reality into apparent and hidden. The apparent reality becomes a space for the existence of ordinary citizens and the implementation of legal procedures, while the hidden one contains a system of real circulation of power, which is not regulated by any legal regulations, instead, controls all movements of the social body. The systemic role in the hidden society is played by cliques — informal groups of influential people who really control the course of events. The con- sequence of the principle of domination is the passivity and marginalization of the Ukrainian citizen, associated with the defect of political participation. Such non-participation in power is embodied in such forms of consciousness as hope, liking, and despair. Today, independence is not a given, but a chance that must be realized. The way to this is through the restoration of the role of the people as a sovereign power and the development of non-dominant regulatory factors of sociality.

Дослiджувалась кристалiзацiя CaSO4 · 2H2O при змiнi концентрацiї iонiв Ca2+ i постiйнiй концентрацiї SO2−4. Встановлено, що концентрацiя комплексiв CaSO04 може перевищувати концентрацiю iонiв Ca2+, що впливає на умови кристалiзацiї, зокрема, на перенасичення. За даними вимiрювань iндукцiйного перiоду визначено поверхневу енергiю зародкiв i встановлено, що вона змiнюється в межах 6,4–10,8 мДж/м2 залежно вiд спiввiдношення мiж концентрацiями iонiв кальцiю i комплексiв CaSO04. Вважаємо, що величина поверхневої енергiї залежить вiд умов формування протозародкiв. Приймаємо, що протозародками є мiцели, ядра яких при переходi вiд CCa2+ < CSO2−4 до CCa2+ > CCaSO04 > CSO2−4 зазнають перезарядки.

This research is motivated by the success of the PAUD Terpadu Al Furqan Jember in developing students' potential, academic, and non-academic achievements. This success cannot be separated from human resource management, especially teachers as educators. This study aimed to determine the process of human resource management for teaching staff at PAUD Terpadu Al Furqan Jember. This type of research is descriptive qualitative with observation, interviews, and documentation as data collection methods. The results showed that the human resource management process in PAUD Terpadu Al Furqan Jember was carried out in planning, organizing, developing, and evaluating. The planning stage began with a needs analysis by the principal, followed by recruitment by the foundation. The principal's organizing stage is carried out by coordinating human resources' placement according to expertise and the appointment of a companion teacher to assist the apprenticeship program for new teachers. Schools and foundations carry out the development stage in competency improvement and quality control activities, routinely held every Saturday. The evaluation phase is carried out once a week after development activities and at the end of each semester carried out by the principal, peers, and parents. The evaluation results' follow-up is the existence of coaching carried out by the foundation and the school in constructive personal criticism, followed by training attended by all human resources.

A 27-years-old female with multiple autoimmune disorders presented to our cardiology unit for acute chest pain and worsening dyspnoea. Admission blood tests revealed increased serum levels of high-sensitive cardiac troponin, eosinophilic count and C-reactive protein. Laboratory findings, low QRS voltages by ECG, mildly reduced left ventricular systolic function in the context of pseudohypertrophy, mild and diffuse late gadolinium enhancement associated with markedly increased native T1 and T2 mapping levels assessed by echocardiography and cardiovascular magnetic resonance imaging, raised the suspicion of massive eosinophilic myocarditis, subsequently confirmed by histological examination of endomyocardial biopsy. Prompt initiation of immunosuppressive treatment allowed swift regression of myocardial inflammation and full recovery of left ventricular systolic function within one month. After ruling-out clonal myeloid disorder, lymphocyte-variant and reactive hypereosinophilia, the young lady was eventually diagnosed with idiopathic hypereosinophilic syndrome. This case report turns the spotlight on the role and importance of advanced multi-modality cardiovascular imaging for raising clinical suspicion of acute eosinophilic myocarditis, guiding diagnostic work-up and monitoring response to treatment.

Soviet Heavy and Super-Heavy Artillery During the Great Patriotic War 1941-1945
Authors: Alexey Isaev
Published: September 2021

The article is dedicated to the usage and types of Red Army heavy and super heavy artillery during the Great Patriotic War. The purpose of the article is to define the exact reasons of low intensity use of Soviet heavy and super-heavy artillery during the war: virtually retreat during 1941-1943 and slow increase of usage during 1944-1945. High intensity of heavy artillery service took place just in 1945. This question has several answers: Red Army high command concerns about expensive guns lost in combat, specific conditions on the Eastern front, incompetence of command is all invalid. Research is based on comparison of archival materials in the field of ordnance production and expenditure. By the use of statistics it described the ordnance production and inventory. The materials show that ordnance production for heavy and super-heavy artillery in USSR was inadequate before the war. Due to the defeat of the Red Army in 1941 the situation worsened. The exact cases were analyzed on the basis of technical and managerial decisions. Ordnance prices and plants involved in ordnance production have also been considered by the research. Exact samples of heavy artillery usage are described with necessary statistics about it: Rzhew battles in 1942, Volkhov battles in 1943. Red Army statistics is compared with Wehrmacht statistics and US statistics of ordnance expenditure. In conclusions it has been shown the interconnection between intensity of use and ordnance provided by war economy.
"Save the Trusted Evacuated Property": about the Work of the Base for the Astray-Evacuated Cargo Under the Molotovsk Regional Executive Committee in 1941–1943
Authors: Yulia Kashaeva

Organization of the state and private goods evacuation, its placement in the rear regions of the country was an important and complex task for the authorities of all levels. In the process of evacuation, during the change of the points of goods delivery, the movement in the most difficult conditions of 1941, the loss of accompanying forms by virtue of a number of reasons, and at the same time the rapid deployment of evacuated enterprises and institutions in the rear it was necessary to organize the receipt and use of the undocumented goods. The evacuation of population was accompanied by sending luggage with personal home property as it was designated in the documents. At the same time the luggage was not always arrived at the destination or citizens were placed in the planned place of evacuation. Originally all these problems were regulated by the Resolution of the Council of People's Commissars of the USSR No. 1869-84 from July 15, 1941 "On the points of discharge of the astrayevacuated cargo from the immediate battle area". After that evacuation bases were founded in a number of large rear cities. Their activity was regulated by the Decrees of the USSR CPC, the orders of the USSR SPC, the Council for the evacuation of the USSR. The Molotov base of the astray-evacuated cargo was formed on July 21, 1941 as a part of the regional executive committee and continued its activity until August 20, 1943. The base realized a receipt, segregation, assessment and storage of evacuated cargo from the immediate battle area which did not have a certain recipient or accompanying forms. The base carried out the distribution, implementation and vacation of property and goods to enterprises in the territory of Molotov region, carried out storage, search for the owners and sending the property to the citizens. The main sources for studying the work of the Evacobase were the documents of the R-353 Foundation "Molotov Base of Astray-Evacuated Cargo under the Executive Committee of the Molotov Regional Council of Deputies of Workers, Molotov" (State Archive of the Perm Territory). The total set of documents concerning the base functioning including basic documents, book-keeping and order ones, as well as documents on the base personnel makes possible to study various aspects of evacuation and placement of goods of enterprises and property of citizens.
Reduced order modeling for stochastic prediction and data assimilation onboard autonomous platforms at sea
Authors:   , Heuss Jacob P.
Published: September 2021

There are many significant challenges for unmanned autonomous platforms at sea including predicting the likely scenarios for the ocean environment, quantifying regional uncertainties, and updating forecasts of the evolving dynamics using their observations. Due to the operational constraints such as onboard power, memory, bandwidth, and space limitations, efficient adaptive reduced order models (ROMs) are needed for onboard predictions. In the first part, several reduced order modeling schemes for regional ocean forecasting onboard autonomous platforms at sea are described, investigated, and evaluated. We find that Dynamic Mode Decomposition (DMD), a data-driven dimensionality reduction algorithm, can be used for accurate predictions for short periods in ocean environments. We evaluate DMD methods for ocean PE simulations by comparing and testing several schemes including domain splitting, adjusting training size, and utilizing 3D inputs. Three new approaches that combine uncertainty with DMD are also investigated and found to produce practical and accurate results, especially if we employ either an ensemble of DMD forecasts or the DMD of an ensemble of forecasts. We also demonstrate some results from projecting / compressing high-fidelity forecasts using schemes such as POD projection and K-SVD for sparse representation due to showing promise for distributing forecasts efficiently to remote vehicles. In the second part, we combine DMD methods with the GMM-DO filter to produce DMD forecasts with Bayesian data assimilation that can quickly and efficiently be computed onboard an autonomous platform. We compare the accuracy of our results to traditional DMD forecasts and DMD with Ensemble Kalman Filter (EnKF) forecast results and show that in Root Mean Square Error (RMSE) sense as well as error field sense, that the DMD with GMM-DO errors are smaller and the errors grow slower in time than the other mentioned schemes. We also showcase the DMD of the ensemble method with GMM-DO. We conclude that due to its accurate and computationally efficient results, it could be readily applied onboard autonomous platforms. Overall, our contributions developed and integrated stochastic DMD forecasts and efficient Bayesian GMM-DO updates of the DMD state and parameters, learning from the limited gappy observation data sets.
