The associations of tobacco use, sexually transmitted infections, HPV vaccination, and screening with the global incidence of cervical cancer: an ecological time series modeling study
Authors: Zheng Luyan , Lin Yushi , Wu Jie , Zheng Min
Published: December 2022

OBJECTIVES: We aimed to quantify the temporal associations between cervical cancer incidence and cervical cancer-related factors and to predict the number of new cervical cancer cases averted under counterfactual scenarios compared to the status quo scenario.METHODS: We described temporal trends in cervical cancer and associated factors globally from 1990 to 2019. We then used generalized linear mixed models to explore the impact of tobacco use, sexually transmitted infections (STIs), human papillomavirus (HPV) vaccination, and cervical screening on cervical cancer incidence. A counterfactual analysis was performed to simulate the most effective scenario for reducing cervical cancer incidence.RESULTS: The worldwide incidence of cervical cancer showed a downward trend over the past 3 decades (estimated annual percentage change, -0.72%), although the incidence remained high (>30 cases per 100,000 persons) in sub-Saharan Africa, Latin America, and the Caribbean. Higher smoking and STI prevalence showed significant direct associations with the incidence of cervical cancer, whereas HPV vaccination and screening coverage showed significant inverse associations. If the strategic goals for accelerating the elimination of cervical cancer and tobacco control programs had been achieved in 2019, the largest decrease in the number of new cervical cancer cases would have been observed, with 54,169 fewer new cases of cervical cancer in 2019.CONCLUSIONS: Our counterfactual analysis found that a comprehensive intervention program emphasizing scaled-up cervical screening coverage (70%), HPV vaccination coverage (90%), and tobacco control (30% relative reduction) would be the most effective program for reducing cervical cancer incidence.
О точной теореме Бэра-Сузуки для $\pi$-радикала конечной группы
Authors: Yang Nanying , Wu Zhenfeng , Revin Danila Olegovich , Vdovin Evgeny Petrovitch
Published: December 2022

Пусть $\pi$ - некоторое собственное подмножество множества всех простых чисел. Обозначим через $r$ наименьшее простое число, не лежащее в $\pi$, и положим $m=r$, если $r=2,3$, и $m=r-1$, если $r\geqslant 5$. Изучается гипотеза о том, что класс сопряженности $D$ конечной группы $G$ порождает $\pi$-подгруппу в $G$ (эквивалентно, содержится в $\pi$-радикале) тогда и только тогда, когда любые $m$ элементов из $D$ порождают $\pi$-группу. Доказано, что данная гипотеза верна, если всякий неабелев композиционный фактор группы $G$ изоморфен спорадической, знакопеременной, линейной или унитарной простой группе.

West Nile virus (WNV) is prevalent in the United States but shows considerable variation in transmission intensity. The purpose of this study was to compare patterns of WNV seroprevalence in avian communities sampled in Atlanta, Georgia and Chicago, Illinois during a 12-year period (Atlanta 2010–2016; Chicago 2005–2012) to reveal regional patterns of zoonotic activity of WNV. WNV antibodies were measured in wild bird sera using ELISA and serum neutralization methods, and seroprevalence among species, year, and location of sampling within each city were compared using binomial-distributed generalized linear mixed-effects models. Seroprevalence was highest in year-round and summer-resident species compared with migrants regardless of region; species explained more variance in seroprevalence within each city. Northern cardinals were the species most likely to test positive for WNV in each city, whereas all other species, on average, tested positive for WNV in proportion to their sample size. Despite similar patterns of seroprevalence among species, overall seroprevalence was higher in Atlanta (13.7%) than in Chicago (5%). Location and year of sampling had minor effects, with location explaining more variation in Atlanta and year explaining more variation in Chicago. Our findings highlight the nature and magnitude of regional differences in WNV urban ecology.
Anaerobic co-digestion of sewage sludge and Cladophora green algae: Investigation of synergistic effects and Optimization of substrate composition ratio
Authors: Rasouli Majid , Dini Mahdi , Ataeiyan Behnam
Published: December 2022

Anaerobic co-digestion of primary and secondary sewage sludge and Cladophora green algae was investigated under mesophilic temperature conditions. The design of experiment method and the optimal mixture design were used to systematically optimize the substrate composition ratios and elucidate the possible synergistic effects for an anaerobic digestion system. A reduced cubic model was created by Design-Expert software as a function of substrate composition ratios. The model was validated by ANOVA experimentally. Also, the substrate composition ratio's effects on variations in biogas production were studied. All linear impacts on changes in biogas production were significantly observed, and interactions between substrates in combined digestion had synergistic impacts on biogas production rate. The highest amount of biogas (235.17-296.03 ml/g VS) was obtained with ratios of equal to 70-60%, B equal to 0-17%, and C equal to 18-30%. Eventually, the model optimization was performed to predict the optimal conditions to achieve the maximum biogas production rate. It was seen that the predicted and actual values of produced biogas in favorable conditions with an error of about 1.3% are well consistent. The authors conclude that the optimal mixture design can be utilized to assess the optimal composition of substrates in an anaerobic digestion system.
Facile, green approach for aqueous methylene blue dye adsorption: Coconut vinegar treated Trema orientalis wood biochar
Authors: Udawatta M.M. , De Silva R.C.L. , De Silva D.S.M.
Published: December 2022

Biochar is widely utilized in low-cost water treatment. However, chemicals used in most of the recorded activation techniques are corrosive, may cause secondary pollution, and not accessible by rural communities, reducing their value of being cost-effective. In this study, Trema orientalis wood biochar (WB) was successfully activated with natural coconut vinegar employing a facile technique to produce a green adsorbent for efficient aqueous methylene blue (MB) removal. Batch studies showed a three-fold higher MB adsorption capacity of coconut vinegar treated wood biochar (CVWB) compared to WB. Percentage removal ranged between 98-79% at lower dye concentrations (50-100 mg/L) and 79-48% at higher dye concentrations (100-300 mg/L). Isotherm data best fitted to the Freundlich model. Kinetic data fitted to both pseudo second order and intraparticle diffusion models, suggesting that the adsorption was governed by a pore filling mechanism with predominant electrostatic attractions, and the reaction rate was diffusion controlled. FTIR, XPS, and water contact angle measurements confirmed increased surface oxygenated groups of CVWB. XPS showed a three-fold increase in O/C atomic ratio. BET and AFM studies gave evidence to the increased porosity. Therefore, the enhanced MB adsorption capacity of CVWB was attributed to both the increased surface oxygenated functional groups and porosity.

ABSTRACT

Digitalization affects and transforms areas that are an integral part of daily life such as education, economy, entertainment and communication. It is seen that people in both developed and developing countries, where more and more products and services are provided to users in digital environments, are increasingly benefiting from digitally provided environments. It is stated that blogs, which are different from other popular communication protocols based on the Internet, have a democratizing potential. Blogs, which can be a source for sharing news and creating public opinion, can be created under the umbrella of an institution or organization. Blogs, which can also be put forward within the framework of individual purposes, emerge as one of the new ways to communicate with others, and allow personal expressions such as feelings, thoughts and preferences to be shared with a wider audience. The content of blogs, which can be text-based as well as video content, has a great variety. Studies that evaluate blogs according to these differences in terms of species are functional in terms of examining their contents in detail. This study focuses on the video diaries produced by Turkish vloggers. In the study, in which literature review was used as a method, 18 vlog channels with more than two million subscribers were evaluated according to the vlog types determined by Gercely (2018). It was determined that 8 of them were jokes and comedy, 3 of them were gaming, 2 of them were training/teaching, 1 of them was beauty/fashion/fitness, 1 of them was lifestyle, and 1 of them was product review. More than two million Turkish vloggers could not be identified in the movie/TV/book commentary and travel vlogs. Vloggers with the highest followers at the time of the research were evaluated under these headings.

Günlük yaşam seri üretim ve seri tüketimle doğrudan ilişkilidir. Tek kullanımlı ya da uzun ömürlü olmayan nesnelerin günlük yaşamımızda iyiden iyiye yer alması sonucunda sıradan olanın artık vazgeçilemez bir ekonomik terim olduğu gerçeği ile karşı karşıya bulunmaktayız.

19.yy.’ın ortalarında başlayan Sanayi Devrimi, kırsal kesimden kentlere göçü başlatmış, kent varoşlarına yerleşen köylülerin kentli görünme sevdası ile pahalı günlük kullanım eşyası almak yerine daha ucuz ve basit malzemeden yapılmış taklit eşyayı satın alma tercihiyle kitsch’in oluşumuna ciddi bir zemin hazırlamıştır. Günümüzün tüketime dayalı ekonomik sistemi, 19.yy.’ın bu ekonomik sistemini olanca hızı ile sürdürünce taklit ürün üretimi kaçınılmaz olarak devam etmiştir. Üreten için önemli olan biçim/form değil, fonksiyonellik olmuştur.

Tüketim toplumunun bu basit mantığı, sanatın da temelini oluşturmakta, içeriğin/anlatının biçimden bir adım daha öne çıkmasına neden olmaktadır. Sanatsal zevkin basit ve sıradan olaylardan beslendiğinin farkında olan günümüz sanatı kitsch’i artık sanatın asıl dinamiklerinden biri olarak görmektedir. Nitel araştırma yöntemiyle yapılan bu çalışma konuyla ilgili kitaplar, dergiler ve internet kaynaklarından yararlanılarak gerçekleştirilmiştir. Betimsel analiz yöntemiyle güncel sanatçıların kitsch eserleri çözümlenerek sonuca ulaşılmıştır.
GERÇEK SANALLIĞIN SİMÜLASYONUNDAN BİLİNÇ KAVRAMINA BAKIŞ: “UPLOAD” DİZİSİ
Authors: BASMACI Pınar
Published: December 2022

Üç boyutlu ve gerçeğin yeniden üretildiği bir dünya olan sanal gerçeklikten farklı olarak Castells’in gerçek sanallığında, gerçek ile temsili gerçek arasındaki fark ortadan kalkmıştır. Her şeyin sembolik olduğu bu dünyada, temsili ortamın sanallığı gerçeğin yerini almıştır. Başka bir deyişle ise taklit olan, gerçek olanın yerine geçmiştir ki bu da aynı zamanda simülasyondur. Gerçeğin temsiline dayanan simülasyon için Baudrillard, dünyanın bir simülasyon olduğunu ve hakikat ile simülasyonun sınırlarının belirsizleştiğini söylemektedir. Gerçek ve temsillerinin birbirine karıştığı bu ortamda, bilinç ise önemli bir kavram olarak durmaktadır. Zihnin farkında olma durumu olan bilinç, bedenden bağımsızdır ve bedenin yokluğunda dahi var olabilmektedir. Bu bağlamda Upload dizinin ele alındığı bu çalışmanın konusunu, gerçek sanallık ve simülasyon bağlamında bilinç kavramı oluşturmaktadır. Çalışmanın problemi, dizideki dünyanın sanal gerçeklik mi yoksa gerçek sanallık kavramına mı karşılık geldiği ve söz konusu simülasyon dünyasında bilincin nasıl konumlandırıldığıdır. Gerçeğin anlamını yitirdiği ve sanallığın hâkim olduğu bu dünyada, bilincin anlamını yitirip yitirmediğini ve bilincin bedenden özgür olup olmadığını ortaya koymak ise çalışmanın amacını oluşturmaktadır. Söylem analizi yönteminin kullanıldığı çalışmada, dizinin tüm bölümleri incelenmiştir. Çalışmada, dizide ortaya konan dünyanın sanal gerçekliğe değil, gerçek sanallığa karşılık geldiği ve her şey bir simülasyondan ibaret olsa da bilincin gerçek olabileceği, ebediyen var olabilmesi mümkün olan bilincin simülasyonunun olamayacağı ve tüm sanallığın içerisinde dahi varlığına koruyabileceği sonucuna varılmıştır.

İnsan kendi dışındaki uyaran ve motivasyonlara karşı, verdiği tepkilerle/tercihlerle yaşamını biçimleyen ve “daha” diyen yegane varlıktır. Tavır, davranış birlikteliği ile açıklanabilecek günümüz kültüründe yönelimin dijitalleşme odaklı olduğu söylenebilir. Dijital kültürde yapay yaşam, sanal mecradaki yazılım ve donanım tabanlı yaşam formlarını, biyokimyasal malzemelerle laboratuvar ortamında yeni yaşam biçimleri meydana getirmeye dayalı çalışmaları, mekatronik ve holografik yapay yaşamları kapsamına almaktadır. Karmaşık algoritmalarla biyolojik ilkeler modellenmekte, gerçek ve yapay arasında yeni bir ilişki oluşmaktadır. İçerdiği yöntemler açısından doğadaki ve yaşam sistemlerindeki değişimlere benzer yapay yaşam, sanat üretim sürecinde yeni yaklaşımları da beraberinde getirmektedir.

Sanatsal üretimlerde yapay yaşam üç farklı formatta sunulmaktadır. Bunlar gerçek mekanda robotik yaşamlar, gerçek mekanda sanal yaşamlar, sanal mekanda sanal yaşamlar şeklinde sıralanabilir. Bu üretimler kurgulanan algoritmaya göre veya çevreyle etkileşim sonucunda hareket etmekte, evrimsel gelişimini tamamlamaktadır. Yapay yaşam projelerinde, doğadaki karmaşık sistemler basite indirgenmekte ve yaşamın temel özellikleri ile ilgili çalışmalar sürdürülmektedir. Araştırmanın başlıca amacı farklı kombinasyonlarda oluşturulan yapay yaşam sanatını yaşam ve yaşanan mekan olgusu bağlamında incelemektir. Bu araştırma günümüzde sanatla iç içe olan yapay yaşam temelli yaklaşımları çözümleyebilmek, sanata sunduğu açılımları anlayabilmek ve sanatın geleceğine dair yorumlarda bulunabilmek açısından önemlidir.
Kriz Dönemlerinde Enformasyon Süreçleri: Ukrayna-Rusya Savaşında Dolaşıma Giren Sahte Haberlerin Analizi

Published: December 2022

Kişiler arası ve kitle iletişiminde internetin ortaya çıkmasıyla birlikte yaşanan büyük değişim, enformasyon ekosisteminde yeni sorunları beraberinde getirmiştir. Sosyal medyanın merkezini oluşturduğu yeni medyada kullanıcıların içerik üretimi sürecine dahil olması, haber ve bilgi güvenilirliği açısından tarihi bir kırılmaya neden olmuştur. Doğru bilgiye ulaşma ve teyit süreçlerinin büyük ölçüde ortadan kalkması ve enformasyon yoğunluğunun görülmemiş şekilde artması, haber tüketicilerinin doğru bilgiye ulaşmasını zorlaştırırken, yanlış bilgi ve dezenformasyon sorunu kullanıcıların hakikatle olan bağlarına zarar vermiştir.

Bilgiye ihtiyacın arttığı ve doğru bilgiye ulaşmanın zorlaştığı, bu nedenle bilgi açığı oluşan kriz dönemleri, yanlış bilgi ve sahte haberlerin en çok yayıldığı dönemler olarak dikkat çekmektedir. Savaşlar da, özellikle propaganda amaçlı sahte haberlerin üretildiği ve dezenformasyon faaliyetlerinin arttığı önemli krizlerdir. İkinci Dünya savaşı ve sonrasında yoğun şekilde görülen ancak profesyoneller (devletler, istihbarat örgütleri vb) tarafından yapılan ve kasıtlı olarak, zarar verme amacıyla üretilen mesajlar olarak tanımlanan dezenformasyon, yeni medyada kullanıcılar tarafından daha kolay yapılmakta ve daha büyük kitlelere, daha hızlı ulaştırılmaktadır.

Bu çalışmada, Ukrayna-Rusya Savaşı bağlamında yanlış bilgi ve sahte haberlerin Türkiye’de ne ölçüde dolaşıma girdiği, dezenformasyon süreçlerinde aktörlerin kimler olduğu belirlenmesi amaçlanmıştır. Türkiye’deki doğrulama platformlarının ortaya koyduğu doğrulama analizlerin incelenmesi sonucunda, savaşın ilk döneminde yoğun şekilde yanlış bilgi ve sahte haberin sosyal medyada dolaşıma girdiği, ağırlıklı olarak sıradan kullanıcıların bu bilgileri yaydığı, sahte haber türlerinden en fazla, farklı tarih ve bağlama ait görsel ve videoların yaygınlaştırıldığı, Türkiye’de dolaşıma giren iddiaların Ukrayna’dan çok Rusya’yı hedef aldığı belirlenmiştir.

The Beauty, the Beast and the Red Hare. The 'Chain Scheme' in Chinese Literature and Cinematography. Part 1
Authors: Sarakaeva Elina A.
Published: December 2022

The Chinese historical chronicle “The Annals of the Three kingdoms” relates the last years of Han dynasty before the country fell into chaos. According to the Chronicle, a frontier general Dong Zhuo marched with his troops to the capital and took control over the boy emperor. He wanted to get rid of his rival general Ding Yuan, so he bribed his officers with gifts and promises. A young junior officer Lü Bu killed general Ding and presented his head to Dong Zhuo. The daring and unscrupulous officer enjoyed the favours of the usurper, he became his adopted son and was placed at the head of cavalry. To his misfortune, Dong Zhuo’s uncontrolled temper threatened the very life of his closest henchmen. Besides, Lü Bu’s regiments didn’t enjoy benefits they expected and that annoyed the soldiers and their new commander. Finally, Lü Bu started a secret affair with a court lady and was afraid to be exposed. So, when minister Wang Yun asked him to kill the tyrant, Lü Bu agreed. Following Wan Yun’s plan, he killed Dong Zhuo with his own hands. This story was masterfully re-worked in Luo Guangzhong’s great epic “The Three Kingdoms”. The writer dramatized the plot and turned the nameless court lady into a renowned beauty Diao Chan who plays the key role in the conspiracy. According to the novel, Diao Chan seduced Lü Bu and later married Dong Zhuo to set the tyrant and his powerful bodyguard against each other. This scheme was called “The Chain Scheme”, for the idea was to break the chain between the male characters with the help of female charms. The Chain Scheme is the most stylistically strong and textually rich episode; in the course of Chinese history it served as a plot to masterful works of fiction and in 20th-21st centuries got numerous TV adaptations. In the present paper I analyse artistic devices and narrative tropes in literature versions of Chain Scheme plot, paying attention to the visual images of the characters, especially their bodily representations as well as the psychological interpretations of their actions. In the Part II of the work I hope to do the same for the screen versions of the Chain Scheme story.

PERCEIVED ACADEMIC CONTROL AND ACHIEVEMENT: THE MEDIATING ROLE OF BOREDOM DURING ONLINE TEACHING
Authors: Ranđelović Kristina , Minić Jelena
Published: December 2022

The transition to online teaching due to the pandemic provides optimal conditions for analyzing the complexity of cognitive assessments in the context of education. Perceived academic control (PAC) allows students to recognize their responsibilities in online learning and achieve better learning outcomes. This study aimed to examine whether the experience of boredom in online teaching can be a mediator in the relationship between PAC and academic achievement of pupils and university students. The sample consisted of 18 pupils and 111 university students, 30% male and 70% female, aged between 18 and 29 (M = 21.41; SD = 2.45), who attended online classes during the second year of the pandemic. The results of the study confirmed the hypothesis that the experience of boredom in online teaching is a statistically significant mediator in the relationship between academic control and average grade (b = .192, 95% CI [.073, .347]). Still, this mediation is partial, because the direct effect between academic control and grade point average remains significant (b = .323, 95% CI [.111, .536]). Also, PAC is associated with pupils’ and university students’ academic achievement, and this connection is mediated by emotions related to teaching. Boredom in the classroom is closely associated with low PAC, resulting in lower academic achievement. We can conclude that pupils and university students more often perceive learning as boring due to the inability to control teaching activities in the research conducted during the pandemic, which may be in correlation with poorer achievements. Given the probability that online teaching will continue, implications for research and practice as well as future research opportunities are discussed.

Authors: Todosijević Marija , Kojić Dijana
Published: December 2022

The purpose of this research was to explore if the differentiation of self has a role in predicting capacity for mentalization in female samples. The data was collected using The Reflective Functioning Questionnaire (RFQ) and The Differentiation of Self Inventory (DSI) on a sample of 105 female participants, aged 18-50 years (M = 30.61, SD = 8.09). Both models containing self-differentiation as predictors were significant. The first model that predicted certainty about mental states explains 32.1% of the variance (R² = .32, F(6,98) = 7.732, p = .000), with I position (β = .459, p = .000) and emotional cutoff (β = -.245, p = .024) as significant predictors. The second model that predicted uncertainty about mental states explains 40.4% of the variance (R² = .40, F(6,98) = 11.086, p = .000), with age (β = .233, p = .007), education (β = -.208, p = .024), and emotional reactivity (β = .323, p = .005) as significant predictors. The obtained results indicate that different aspects of the differentiation of self can predict certainty and uncertainty about mental states in the female sample, but also that when it comes to phenomenon such as capacity for mentalization, certain sociodemographic variables (e.g., age, education) might play more important role then it was previously thought. Further research on this matter, with a bigger and more diverse sample, is strongly advised. Keywords: mentalization, self-differentiation, emotional reactivity, emotional cutoff

The aim of this research was to examine the predictive power of gender, the dimensions of perceived parental rearing attitudes, empathy and locus of control in predicting social anxiety among students. The sample consisted of 297 students (71.7% female), aged 19 to 36 years (M = 22.29, SD = 2.46). Parental Rearing attitudes were operationalized through the score on the Parental Rearing Style Scale (dimensions: warm, cold, permissive and restrictive upbringing of the father and mother). Empathy was operationalized through the score on the Empathy Quotient, locus of control was operationalized using the Externality Scale, while social anxiety was measured using the Social Anxiety Scale. The results of the hierarchical regression analysis, in which the first model consisted of the gender variable, showed that this model as a whole is statistically significant (R2 = .021, F(1,295) = 6.290, p = .013). In the second step, the dimensions of parents’ educational attitudes were included and the results showed that their contribution in predicting social anxiety is statistically significant, as well as that the model as a whole is statistically significant (R2 = .106, F(7,289) = 4.881, p = .000). Gender was singled out as a statistically significant predictor within this model (β = .145, p = .011). In the third step, Empathy is included and the contribution of this variable in predicting social anxiety is statistically significant, as is the model as a whole (R2 = .150, F(8,288) = 6.363, p = .000). Statistically significant predictors within this model are gender (β = .158, p = .004) and Empathy (β = -.212, p = .000). Within the fourth model, Locus of control is included and the contribution of this variable in predicting social anxiety is not statistically significant, but the model as a whole is statistically significant (R2 = .159, F(9,287) = 6.017, p = .000) and gender (β = .146, p = .009) and Empathy (β = -.195, p = .001) stand out as statistically significant predictors. Conducted analyses show that female persons with lower empathy are more prone to social anxiety. The results are discussed in light of the available empirical evidence.

The main rotor is the principal factor effecting helicopter performance and fuel consumption. There are many basic geometric parameters that constitutive the main rotor design. Radius and chord are among these basic geometric parameters. In this study, it is aimed to examine the effects of variation in radius and chord on required power at different flight conditions. Based on the design values of B0105 and S-76 from utility helicopter the group, the power calculations were made for the main rotor only when the radius and only the chord changed between +8% and -8%, and both parameters changed between +8% and 8%. These calculations were repeated for hover, 50 knots, 90 knots, 130 knots forward flights, and for sea level, 5000 ft, 10000 ft altitudes. With the variation of radius and chord, the cases that the maximum reductions and increases in required power were revealed. Results shows İncreasing the chord alone resulted in an increase in required power in all flight conditions. It has been observed that the combinations obtained by variation the radius and chord of maximum decrease and increase amount in the required power are different from according to the altitude, suspension condition and forward flight velocity.

Models for the calculation of the production of large photovoltaic (PV) power plants with different types of modules (monofacial or bifacial) have been developed in detail in the literature. In addition, detailed models have been developed for PV power plants that have fixed modules as well as PV power plants with tracking the azimuth angle of the Sun and/or the tilt angle of the PV module. On the other hand, due to the increasing installation of PV power plant, their construction is often imposed on the field with complex geometry, so it is interesting to develop models that can optimize the spatial layout and geometric elements of panels on sloping surface in relation on horizontal. Namely, during various analyses in the literature, production models for PV power plants that are planned on sloping terrains have not been developed. Accordingly, in this paper, a procedure was developed for the calculation of the production of PV power plants that are placed on terrain that is not flat, but oriented towards the arbitrary side of the World and with an arbitrary tilt angle.

The formation of the current-sheet-like structure under the influence of the external magnetic field in pinching plasma flows generated by the magnetoplasma compressor has been studied. A set of magnetic and electric probes were used to measure the self-generated magnetic field, electron temperature, and electric field locally with sufficiently high temporal and spatial resolution. The data obtained from the probe measurements were used to plot the spatial distributions of electric current and drift velocity in the plasma stream to identify the patterns of plasma flow. In the presence of external magnetic field, the current density, electron temperature, and the ion saturation current reach a peak in close proximity to the sheet. Measurements indicate the outflow of two electron jets of different temperatures from the layer.

Published: December 2022

The behavior of ion-implanted deuterium in advanced lithium orthosilicate (Li4SiO4) pellets with addition of lithium metatitanate (Li2TiO3), and in reference Li4SiO4 pellets, has been studied. Thermal desorption spectroscopy (TDS) was used to examine the deuterium interaction with radiation defects in materials. Deuterium gas release from studied ceramics has revealed a clear dependence of deuterium trapping behavior on phase composition. The trap strength of radiation defects formed in lithium titanate was found to be higher than in lithium orthosilicate.

Published: December 2022

Evaporation of micro-droplets in an arc plasma flow under the action of a self-consistency electron beam and the condition of direct heating of micro-droplets by fast electrons are considered. It is shown that the plasma is heated under the influence of the beam, even taking into account the fact that the electrons and ions of the plasma lose energy
for the evaporation of micro-droplets. It is demonstrated that small micro-droplets evaporate more intensively. It is shown that the plasma electron density should be optimal. For the destruction of macro-particles in a plasma with a higher concentration, more powerful beams are required than in a case of plasma with a lower concentration.

To study the influence of the magnetic field on the normal low-pressure glow discharge, an electrode coaxial system with a meshy tubular cathode and an internal anode was used. A current was passed through the anode to obtain the azimuthal magnetic field crossed with electric field. Oscillography of the signals from the electric probe and photodiode, together with video recording, made it possible to establish the movement of the discharge luminous region along the electrodes. When AC current with a frequency of 50 Hz was passed through the anode, the discharge movement was oscillatory – from one end of the system to another.

Nanostructured ZrN coatings were deposited by the vacuum arc method with partial separation of the plasma flow from macroparticles using a curvilinear magnetic filter. With the proposed deposition parameters, a ZrN coating with an fcc lattice and (111) texture is formed. Theoretical studies are carried out to assess the defects of the surface layer in the
presence of an adsorbed impurity of an fcc lattice with the surface orientation plane (111), and the characteristics of surface waves in the ZrN coating are considered. Equations are obtained for the dispersion laws and parameters of the splitting off of the surface wave from the zone of bulk vibrations in the nearest-neighbor approximation.

The properties of Ti41Zr38.3Ni20.7 thin films under radiation-thermal action of hydrogen plasma with a surface heat load of 0.2 MJ/m2 was studied at the QSPA Kh-50 quasi-stationary plasma accelerator (NSC KIPT).The phase composition, structural state, and surface morphology were studied using X-ray diffraction and scanning electron microscopy. It was found that the quasicrystalline phase and related crystalline phases, the Laves phase, the α-solid solution, and the 2/1 phase of the Ti-Zr-Ni approximant crystal were stable under irradiation with up to 20 hydrogen
plasma pulses. The phase composition did not change. It is shown that the changes in the coatings mainly manifest themselves as changes in the substructure of the observed phases. With an increase in the plasma exposure dose, the
structure of the quasicrystalline icosahedral phase improves, and the size of the coherence regions increases. In the films consisting of crystalline phases, a partial phase transformation is observed with a redistribution of components between the 2/1 phase of the approximant crystal and the α-solid solution phase. It was found that thin films of the TiZr-Ni system containing a quasicrystalline icosahedral phase, irradiated with radiation-thermal plasma pulses, are less prone to cracking than coatings with crystalline phases of the same system.
