Transformation priorities in the editorial policy of a Russian scientific journal in the context of international sanctions
Authors: Turgel I. D.
Published: August 2022

The current sanctions introduced against Russian science are imposing serious consequences    on interactions between researchers all over the world. In order to analyse approaches to mitigating the resulting negative effects, the author turns to the theories of external shocks and crisis management. Criteria that characterise modern external shocks are distinguished, on which basis transformations in the editorial policy of a Russian journal aimed at minimising the effects of international isolation under the conditions of limited resources are proposed. Priority directions in the editorial policy include shifting the geographical focus of editorial activities, restructuring the editorial portfolio in favour of review articles and special issues, rethinking the role of email marketing strategies and promoting journals through alternative social networking resources. Each transformation direction is discussed in terms of feasible implementation tools. The importance of monitoring emerging types of articles that are promising from the standpoint of increasing the visibility and recognition of a journal (such as those outlining frontier research directions) is emphasized. The author argues that the proposed transformations in the editorial policy of a journal entails no radical changes in the thematic scope or content selection process. Moreover, these measures can be tailored to meet the specific needs of a particular publisher. Directions for future research are outlined.
Editorial policy in promoting scientific periodicals (on the example of the Gyroscopy and Navigation journal)
Authors: Taranovskiy D. O.
Published: August 2022

The paper describes the editors’ experience of development and promotion of a scientific and technical journal Gyroscopy and Navigation intended for scientists and specialists in the art, and published in the Russian and English versions. The effectiveness of various tools for increasing the citation of the journal is analyzed, and the examples of their practical use are given. The features of interaction with the authors and readership of both the Russian and English-language versions of the journal, i.e., specialists  in navigation and motion control of various moving objects are shown. Work with the Russian-speaking audience of the journal is based on direct contacts with researchers through online seminars, which facilitates the formation of a community of scientists loyal to the publication and interested in the journal development. At present, one of the main goals of the journal is to increase the level of its global reputation and influence. This is solved by sending regular information letters about the publication of new issues   of the journal with a brief description of published materials to particular addressees. As a result of the measures taken, the number of downloads of full texts of articles in the English version of the journal, as well as their citation, has increased significantly (2.5 times), which, in turn, has considerably increased the rating of the journal in the Scopus database. For example, the CiteScore index increased from 1.7 to 2.6 between 2019 and 2021. In this paper, it is shown that the difficulties in promoting the Russian-language version of the journal are due to the small audience of Russian-speaking specialists in this subject area, and due to the specific procedure of journal ratings calculation in the Russian Science Citation Index.

Prospects for the creating of the image of a highly rated Russian language economic journal
Authors: Lozhnikova A. V. , Elmurzaeva R. A. , Kuznetsov A. A.
Published: August 2022

The article is devoted to the topical issue of the prestige Russian economic scientific journal’s Future. The problems of publishing the scientific research’s results by Russian economists in prestige citing scientific journals are identified. The former official vector to index domestic economic scientific journals in Abstract and Citation Databases (Scopus, Web of Science) without a guaranteed state financial support for the original (in Russian) and translated versions of the journal is criticized. The data on the leading Russian economic scientific journals are compared at the intersection of two lists of scientific journals of the Russian Higher Attestation Commission (main and additional /Abstract and Citation Databases), a list of new scientific specialties of the Russian Higher Attestation Commission, two topics of the NEB elibrary “Economics. Economic Sciences” and “Organization and Management”, as well as the QS subject ranking “Social Sciences & Management”. It is concluded that the model of the Russian economic scientific journal, which is adequate to the current moment, under the conditions of Western sanctions, is not implemented at all. This model involves the publication in the original version in Russian with a translated version, and provides access to them for Russian researchers on unlimited publication topics and for publishing the results of dissertations for the degrees of Candidate of Science, Doctor of Science. The measures of the protectionist policy to keep domestic economic journals with founders-universities are substantiated.
Use of peer reviewing indicators for planning the work of the editorial office of a scientific edition (on the example of a biological journal)
Authors: Morgunova G. V. , Khokhlov A. N.
Published: August 2022

The peer review process is an extremely important and time-consuming step in preparing a manuscript for publication. It often takes longer than all other stages of article processing. Due to the complexity of peer reviewing, it becomes necessary to analyze it and determine the key points that you should pay attention to when planning the work of the editorial office. In this study, the authors used data obtained in the process of work with reviewers of the journals “Vestnik Moskovskogo Universiteta. Seriya 16. Biologiya” and “Moscow University Biological Sciences Bulletin” in 2017–2021, as well as information on articles received by the editorial office in the same period time. The sample of peer reviewers consisted of 319 specialists from various fields of biology and related disciplines. The results of the analysis showed that the average time spent on the primary review was about 11 days, and the average time during which experts respond to the invitation was about 2 days. Reviews received by the editors over five years, on average, contain a little less than 3 000 characters, the volume of reviews does not correlate with the timing of the reviews and their quality. In recent years, the editorial office has managed to reduce the proportion of formal uninformative reviews to 6 %. Both women and men, employees of both universities and research institutes, scientists with candidate and doctoral degrees are equally involved in the work on articles. The important role of reviewers in improving the article and at the same time insufficient encouragement of this important work are emphasized. The results obtained can be useful to the editors of scientific journals when they plan the stages of reviewing articles.

Negative types of authors and their manuscripts in Russian academic periodicals for Humanities and Social Sciences
Authors: Konson G. R.
Published: August 2022

The author based on his experience revealed a typology of quasi-professional researchers and their manuscripts, which are submitted in the Russian academic periodicals for Humanities and Social Sciences. Different methods of declining quality in the context of violation of academic ethics are considered, about 30 kinds of them have been identified. Each of these examples complicates the peerreview process (perhaps without the obtaining of final result). This research has some perspectives to be kind of an academic guide for academic periodicals’ management and for its contributors. Thanks to this project, as its author believes, it is possible to reduce the organizational and time costs for evaluating manuscripts submitted in modern academic periodicals for Humanities and Social Sciences, as in Russia as so in some foreign countries.
Alternative solutions for Russian authors publishing in English-language scientific and engineering journals of China
Authors: Raevskaya E. G.
Published: August 2022

The article presents results of the analysis of Chinese scientific and engineering journals currently included in the leading international citation scientometric databases Scopus and Web of Science focusing at an alternative possibility of publishing articles by Russian authors in Chinese English-language journals. The sufficiently large quantity and high quality of these journals are shown, along with the diversity of their subject categories, and the top ten journals are highlighted. Taking these top ten journals as an example, the terms for publishing are considered, which depend on the use of various publication models (full or hybrid open access), together with different solutions for authors to overcome the problem of high fees for article processing charge in the case when this condition exists. The conclusion is drawn that Russian authors have noteworthy options to publish their articles in the Chinese English-language journals in present-day conditions.
Regulation of scientific journals publishing in Russia: Problems and suggestions
Authors: Gorelkin V. A.
Published: August 2022

The purpose of this article is to demonstrate the main restrictions that domestic scientific journals currently encounter and propose options to support them. In order to accomplish this, the main areas of journals’ verification by the Federal Service for Supervision of Communications, Information Technology and Mass Communications (Roskomnadzor) are analyzed. The proposal to establish a special status for a scientific journal, separating it from the social and political media, is made. Proposals to exclude obsolete and unnecessary requirements from the List of HAC (High Attestation Comission) journals and to include new ones that would improve the quality control of publications have been made. The author makes suggestions on forming a national list of scientific journals and a platform for assessing the quality of publications. It is noted that without considering the opinion of editors and publishers of scientific periodicals, the created “White List” of Russian scientific journals will cause numerous doubts about its objectivity.

Journal quality criteria: Measurement and significance
Authors: Kirillova O. V. , Tikhonova E. V.
Published: August 2022

The landscape of scientific communication imposes obvious requirements on its actors, which are not always unambiguously interpreted by the latter. The basic criterion of scientific communication is its quality. Since scientific journals serve as the main channel for rational debates based on facts, their quality level seems to be the most significant for the development of scientific knowledge. Today, scientific journals are undergoing a massive transformation: from changing the format of content presentation to becoming a body of collective communication. These changes cannot but affect the quality characteristics of journals. Since the changes are multilateral in nature, the scientific, editorial, and publishing communities have not formed an unambiguous opinion about which criteria of the journal characterize its quality aspects, and which can be attributed to “formal”, “technical”. In this article, the authors, based on Russian and international expert opinion, analyze the quality criteria for journals. Based on the data of the questionnaire developed by the authors, which considers the categories and criteria of the Scopus expert system, a survey of editors (n = 130) of Russian scientific journals was conducted. The questionnaire was completed anonymously, and the study participants were made aware of its objectives. The data obtained made it possible to analyze the editors’ ideas about the qualitative characteristics of a scientific journal and their influence on its promotion. A sufficiently deep understanding by the editors of the essence and specifics of the analyzed characteristics was recorded. At the same time, certain aspects require targeted work on their optimization and development. There is also an obvious need for further research on the topic, considering the subject field of journals traditions.
Variable Metric Primal-Dual Method for Convex Optimization Problems with Changing Constraints
Authors: Konnov Igor
Published: August 2022

We propose a modified primal-dual method for general convex optimization problems with changing affine constraints. We establish convergence of the method that uses variable metric matrices at each iteration. This approach yields new opportunities for control of the parameters according to the constraints changes. In case of the multi-agent optimization problems the method can be adjusted to the changing communication topology and enables the agents to choose the parameters separately of each other.
MORPHOLOGICAL DESCRIPTION OF INTERNAL ORGAN COLOR AND ITS RELATIONSHIP TO BODY WEIGHT OF FREE-RANGE CHICKENS IN THE PALEMBANG LANDFILL ENVIRONMENT
Authors: Mutia Nurrahmandani  , Sandi Sofia , Ali Asep Indra Munawar
Published: August 2022

The landfill environment in Palembang City produces various types of waste so that people keep free-range chickens around the environment, which is potentially harmful to livestock health. This study aims to determine the color morphology of the internal organs (liver and heart) and the relationship between body weight and organ weight. The number of free-range chickens used was 30, with one year. The morphological description of organ color was carried out by direct observation, and sampling was carried out by weighing free-range chickens body weight and organ weight. This study used the Pearson correlation statistical test, and secondary data was collected on waste data in the landfill environment. The results showed that the relationship between body weight and liver weight was 0.694, and the correlation value between body weight and heart weight was 0.663 in native chickens in the landfill environment. The results of the two values have a strong correlation interpretation, which means that when the chicken's body weight increases, the weight of the liver and heart of the chicken will also increase. The liver is faded red with normal size in native chickens in the landfill environment in the morphological picture. While the color of the heart is red, and the size is normal.

Published: August 2022

We use mathematical modeling methods to incorporate new elements into the computer graphics technology and visual communication design process. This method realizes the design of a computer image visual communication system. This method uses artificial vision to model and extracts local features. The micro-partial equation obtains the background reference line of the target point in the image sequence to complete the background suppression in the image spatio-temporal domain. The experimental results show that the proposed algorithm has a better tracking effect of subsequent frames of video images and higher tracking efficiency.

Rapid diversification is a way of responding to environmental change for freshwater organisms. This work examined the physicochemical changes and abundance of freshwater snails in Anambra River (Nigeria) during the rainy season. Field studies were conducted fortnightly from June to August 2019 at three stations of the river namely: Otuocha (station I), Otunsugbe (station II), and Ukwubili (station III) about 8.35 kilometers apart from each other. A scoop net of 2 cm mesh size and handpicking was used to sample freshwater snails randomly and water samples were taken to the laboratory for physicochemical analysis. A total of 896 freshwater snails belonging to 6 species (Afropomus balanoidea, Pomacea maculata, Lymnea stagnalis, Lanistes ovum, Pila wernei, and Saulea vitrea) were collected. Pomacea maculata was the most dominant species with a relative abundance of 45.87 %, while Saulea vitrea was the least dominant species with a relative abundance of 2.34 %. There was a significant negative correlation between dissolved oxygen and Pomacea maculate (r = –0.877, p = 0.002) and a positive correlation between dissolved oxygen and Stagnalis lymnea (r = 0.840, p = 0.005). The diversity of species was highest at Otuocha (1.171) followed by Ukwubili (1.133) and Otunsugbe (0.856) with average mean temperatures of (23.1 ±0.1) °C, (27.30 ±0.00) °C, and (26.80 ±0.03) °C respectively. The distribution of freshwater snails was influenced by the physicochemical variability of Anambra River during the rainy season. Therefore, further studies for a longer time and different seasons to examine the impact of physicochemical changes on the snail distribution are encouraged.

Published: August 2022

In this study, removal of colour from wastewaters prepared synthetically using Bomaplex Blue CR-L was investigated using raw and activated pumpkin seed shells by adsorption in a batch system. The effects of stirring speed, adsorbent concentration, dye concentration, temperature and pH on colour removal were investigated, and adsorption capacities of raw and activated pumpkin seed shells were determined. In addition, adsorption kinetics, isotherm coefficients, activation energies and thermodynamic parameters were calculated. The optimal adsorption conditions were determined as pH = 2, stirring speed of 200 rpm, adsorbent concentration of 10 g L−1 and 30 °C. Under the optimal conditions, the maximum removal efficiency of Bomaplex Blue CR-L using raw pumpkin seed shells was 73.01 %. This value rose to 79.71 % after activation processing was applied. Experimental adsorption data show that the adsorption is more suited to the Langmuir adsorption model and works in accordance with the pseudo-first-order kinetics model. As a result of thermodynamic research, ΔH° and ΔS° were 31.515 kJ mol−1 and 109.952 kJ mol−1 K−1 for the raw adsorbent, respectively. For the activated adsorbent, ΔH° and ΔS° were 43.118 kJ mol−1 and 152.237 kJ mol−1 K−1, respectively. The activation energy of adsorption was calculated as 10.918 kJ mol−1 for the raw adsorbent and 9.882 kJ mol−1 for the activated adsorbent.
Research on the Effects of Rare Earth Combined Contamination on Soil Microbial Diversity and Enzyme Activity
Authors: Jiang Ying , Wang Xuemei , Chen Yunzhu , Nengzi Lichao
Published: August 2022

Soil microorganisms and soil enzyme activities are important indexes to evaluate soil status. The soil pollution status was evaluated by measuring the physical and chemical properties and heavy metal content of rare earth combined contaminated soil around the Maoniuping old mining area and tailings ponds in different seasons, and measuring the number and diversity of microorganisms and the soil enzyme activities of the arable soil microecology. This research shows that the physical and chemical properties of farmland soil in old mining areas and tailings ponds in different seasons are significantly different, the concentration of rare earth combined contamination in old mines is greater than that in the tailings area, and the changes in the concentration of rare earth combined contamination cause significant changes in soil microecology. Rare earth combined contamination inhibits fungal and bacterial vital activities and promotes the growth of actinomycetes; reduces the sensitivity of sucrase to heavy metal contamination, promotes the activity of phosphatase, and the effect on urease is that of “promotion at low concentration and inhibition at high concentration”; and reduces the community’s ability to use carbon sources and, as a result, the community species are rare and distributed unevenly and the community structure is simple. These results indicate that rare earth combined contamination is potentially harmful to soil microorganisms, which can provide a theoretical basis for the ecological restoration of farmland soil in mining areas.

Em Minas Gerais, as quedas na incidência foram de 20% de 2019 para 2020 e de 50,27% de 2020 para 2021. Em Belo Horizonte, houve queda de 15,47% na incidência de casos de 2019 para 2020 e de 41,69% de 2020 para 2021. Conclusão: A redução da incidência de sífilis adquirida tem causa multifatorial, destacando-se a subnotificação e a modificação do comportamento humano face ao isolamento social. Essa mudança comportamental pode estar relacionada à diminuição dos parceiros sexuais, da procura por atendimento médico e da oferta de testes rápidos.
Clinical features of herpes simplex virus reactivation after microvascular decompression for trigeminal neuralgia: Experience of 200 patients and a literature review
Authors: Kikuchi Asami , Ishizaki Sumiko , Yokosako Suguru , Kasuya Hidetoshi , Kubota Yuichi
Published: August 2022

Background:

Herpes simplex virus (HSV) reactivation occasionally develops in the early postoperative period after microvascular decompression (MVD) for trigeminal neuralgia (TN). Therefore, the present study investigated the clinical features of this phenomenon.

Methods:

The study cohort comprised 200 patients with 125 women aged between 17 and 90 years (median age, 66 years) who underwent MVD for TN between January 2010 and December 2020. Characteristics were compared between patients with and without HSV reactivation and clinical features were analyzed.

Results:

Twenty patients had HSV reactivation: herpes labialis in 18 and herpes zoster (final diagnosis) in 2. A multivariate analysis revealed independent correlations between postoperative HV reactivation and a previous history of herpes labialis (odds ratios [OR]: 6.32, P = 0.0003) and reoperation for recurrent or persistent pain (OR: 5.06, P = 0.0211). No significant differences were observed in pain relief, postoperative facial numbness, or Barrow Neurological Institute Pain Intensity/Facial Numbness Scores in the past follow-up between patients with and without HSV reactivation. HSV reactivation manifested at a median of the 4th postoperative day (1–10 days) and its location was not related to the preoperative distribution of facial pain. All patients were treated with local acyclovir and were completely cured within 1–2 weeks.

Conclusion:

HSV reactivation occurred in 10% of patients after MVD including 1% of herpes zoster. A previous history of herpes labialis and reoperation was identified as risk factors for reactivation. Symptoms were completely cured by antiviral drugs within 1–2 weeks. It is important to note that cases of herpes zoster may be confused with cases of HSV after MVD.

Authors: Dabhi Nisha , Mastorakos Panagiotis , Sokolowski Jennifer D. , Kellogg Ryan T. , Park Min S.
Published: August 2022

Background:

Drugs of abuse have been associated with ischemic stroke; however, the clinical presentation, outcomes, and treatment data in this population are limited. The overall safety and efficacy of thrombolytic therapy and thrombectomy in these patients remain unclear. This scoping review summarizes published complications and clinical outcomes in patients with recent abuse of cocaine, methamphetamine (MA), cannabis, decongestant, opioids, alcohol, and 3,4-methylenedioxymethamphetamine (MDMA) presenting with acute ischemic stroke.

Methods:

We conducted a scoping review of the primary literature that assessed outcomes data of thrombolytic therapy or thrombectomy in drug users with acute ischemic stroke. We searched PubMed, Ovid Medline, and Web of Science. Demographic and stroke characteristics, treatment, complications, and clinical outcomes at last follow-up were collected and summarized.

Results:

We identified 51 studies in this review. Drugs of abuse of interest were cocaine (14 studies), MDMA (one study), MA (eight studies), cannabis (23 studies), alcohol (two studies), decongestants (one study), and opioids (two studies). Clinical presentation and stroke presentation were most commonly described features. Thrombectomy outcomes were reported for four patients total (two studies), all with history of cocaine use. Thrombolysis treatment and outcomes were reported for 8851 patients (five studies) with history of cocaine, alcohol, or cannabis. Both treatments were pursued in three patients (three studies). Treatment complications included intracerebral hemorrhage, vasospasm, and cerebral edema.

Conclusion:

Evidence for thrombolytic and thrombectomy treatment in drug users remains limited. Controlled studies are needed to examine complication profile and outcomes following thrombolytic and thrombectomy treatment in this population.

İki taraf arasındaki ilişkiler 19. yüzyıl sonları itibari ile başlayan sistematik Yahudi göçleri sonucu ortaya çıkan Filistin meselesinin 1930’larda işgale dönüşmesine kadar gitmektedir. Bu süreçte başlayan karşılıklı ilişkiler sonucu Körfez toplumları ve Filistinliler arasında önemli tarihsel bağlar gelişmiştir. Bunun sonucu olarak Filistin meselesi Körfez ülkelerinde bir kimlik meselesi olmuş ve dış politikalarında temel parametre teşkil etmiştir. Filistinliler, Filistin davası ve Körfez ülkeleri arasındaki güçlü tarihsel bağlar literatüre yansımadığı için yeteri kadar bilinmemektedir. Bu çalışmanın amacı literatürdeki bu boşluğu doldurmak üzere katkıda bulunmaktır. Bu çalışma Filistin ve Körfez arasındaki tarihsel bağların Körfez siyasetinde nasıl etkili olduğu sorusunu cevaplamaktadır. Bu çalışmanın ana iddiası Filistin meselesinin Ortadoğu genelinde ve Körfez özelinde bölgesel siyasetin şekillenmesinde tarihsel olarak belirleyici bir rol oynamakta olmasıdır. Tarihsel süreçte İsrail’in kurulmasına olan dönem, Arap-İsrail Savaşları dönemi, Barış dönemi ve içinde bulunduğumuz İbrahim Anlaşmaları ile başlayan İsrail’le normalleşme dönemi konjonktürü çerçevesinde Filistin meselesi başat faktör olarak bölgesel dinamikleri belirlemiştir. 1973 Petrol Ambargosu bu noktada en çarpıcı örnek teşkil etmiş ve Körfez siyasetinde bölgesel ve küresel sonuçları olan tarihsel bir dönüm noktası olmuşken 2020’de bazı Körfez ülkelerinin İsrail’le normalleşme anlaşması yapmaları Körfez siyasetinde yeni bir dönüm noktası olmuştur.

With the increasing interest in gemstones, which have started to offer an important underground wealth for countries. Menderes Massive is one of the most widespread and most important areas of bauxite deposites in the Turkey. Gemstone quality diaspore crystals are formed only within these deposits. In this study, diaspore formations in the southwest wing of the Menderes Massive (Aydın - Muğla) were examined and their geological, geochemical and gemological properties/characteristics were investigated. Bauxite deposits in the study area are observed along the discordance between white crystallized limestone (lower) and gray-dun colored crystallized limestone (upper) contact. The deposits generally extend in NW - SE direction and the samples show massive, pisolotic, oolitic and leopard texture. Diaspore crystals of different lengths and colors are unique to our country, which starting from Bafa Lake and advancing towards Yatağan in the form of dashed arc. It has been extracted as a by-product as a result of diasporitic bauxite production in a single mine for many years and it is not thought to have an economic value.

Diaspore formations in the study area are generally observed as lenticular, brecciated, cracked and pockets in crystallized limestones, bauxite and altered zones with calcite, muscovite and chloritoid minerals. Diaspores are generally observed in the form of sheet around Milas. Increased interest in diaspore crystal, especially in the last 30 years and this study will be important in terms of gaining the deserved value of diaspore crystal which is unique to our country. Since it is likely that new diaspore deposits will be found in the region, further studies are planned on this subject. The data to be obtained will be important in the determination of new diaspore deposits.

The objectives of this research were to find out which is the more effective learning between online and offline English learning, and the strengths and weaknesses of online learning and offline English learning. A descriptive qualitative research design was used in this research. The results of the research showed that all of the participants perceived that offline learning is more effective than online learning for many kinds of reasons such as offline learning can know and feel the situation directly in the learning process, teamwork is better in offline learning, students focus more to the teachers’ explanation delivered in the classroom. Then, the strengths of online learning are the time, place and condition are flexible and it is able to maintain the teaching and learning process during the Covid-19 pandemic. The weaknesses of online learning are limited interactions among the students, network constraints, and students’ out of control issues. Besides, the strength of offline learning is the ability to interact and share directly in the classroom as well as easy to comprehend the material while the weaknesses of offline learning are the time and place are not flexible and the risk of contagion.

Radical-Polar Crossover Catalysis with a d0 Metal Enabled by a Redox-Active Ligand
Authors: Gavin Joshua , Belli Roman , Roberts Courtney
Published: August 2022

Radical-polar crossover mechanisms are invoked in numerous late transition metal and photocatalyzed reactions. To the best of our knowledge, reductive radical-polar crossover mechanisms are not invoked for group 3 early transition metals due to their propensity to exist in high oxidation states. Through use of a redox-active (tris)amido ligand we have accessed this mechanism for use with early transition metals. This mechanism is showcased through enabling product formation for a wide variety of elimination products from -halo substituted benzylic bromides. The mechanism of this new type of reactivi-ty with Sc is explored and Hammett analysis reveals an anionic intermediate. The wide functional group tolerance of this reaction is also demonstrated.

Yeast use the G-protein–coupled receptor signaling pathway to detect and track the mating pheromone. The G-protein–coupled receptor pathway is inhibited by the regulator of G-protein signaling (RGS) Sst2 which induces Gα GTPase activity and inactivation of downstream signaling. G-protein signaling activates the MAPK Fus3, which phosphorylates the RGS; however, the role of this modification is unknown. We found that pheromone-induced RGS phosphorylation peaks early; the phospho-state of RGS controls its localization and influences MAPK spatial distribution. Surprisingly, phosphorylation of the RGS promotes completion of cytokinesis before pheromone-induced growth. Completion of cytokinesis in the presence of pheromone is promoted by the kelch-repeat protein, Kel1 and antagonized by the formin Bni1. We found that RGS complexes with Kel1 and prefers the unphosphorylatable RGS mutant. We also found overexpression of unphosphorylatable RGS exacerbates cytokinetic defects, whereas they are rescued by overexpression of Kel1. These data lead us to a model where Kel1 promotes completion of cytokinesis before pheromone-induced polarity but is inhibited by unphosphorylated RGS binding.

CuO thin films were produced by the method of reactive magnetron sputtering at direct current in a universal vacuum system Leybold-Heraeus L560 on glass substrates, the temperature of which was: 300 K and 523 K. The structural, electrical and optical properties for the obtained samples of CuO thin films were studied, namely: elemental composition, distribution of elements on the surface, which are part of these films, grain size, activation energy, optical band gap, refractive index, analysis of curves of transmission and reflection spectra for CuO thin films deposited on glass substrates. The elemental composition of the thin films and the surface morphology were performed using a scanning electron microscope (MIRA3 FEG, Tescan) equipped with a reflected electron detector (BSE) and an energy-dispersed X-ray detector (EDX). It was found that the grain size for films obtained at a lower substrate temperature D is ~ 16 nm, and for films obtained at a higher temperature - D ~ 26 nm. On the diffractograms of CuO thin films, a higher peak intensity is observed for thin films obtained at higher CuO no. 2 substrate temperatures, which may be due to better structural perfection of thin films and larger grain size. From the study of electrical properties, it was found that the temperature dependences of the electrical resistance for CuO thin films have a semiconductor character, ie the resistance decreases with increasing T. The surface resistance of the films was measured by the four-probe method: no. 1- ρ = 18,69 kΩ/¨, sample no. 2 – ρ = 5,96 kΩ/¨. Based on independent measurements of the reflection and transmission coefficients, the optical band gap was determined for the two samples by extrapolation of the rectilinear section of the curve (αhν)2 = f (hv) to the hv axis. For the sample CuO №1 Egop = 1.62 eV; for the sample CuO no. 2 Egop = 1.65 eV. For CuO no. 2 thin films, the envelope method was also used to determine the basic optical coefficients Egop = 1.72 eV, and the obtained Egop values determined by the two methods correlate well with each other.
