RESEARCH OF THE VORTEX FLOWS INFLUENCE ON THE NPP ELEMENTS
Authors: Mitrofanova O , Bayramukov A , Ivlev O , Urtenov D , Fedorinov A , Sorokin A
Published: January 2022

The mechanisms of generation of stable large-scale eddies and flow swirling in complex channels of the 1st and 2nd circuits of transport nuclear power plants (NPP) are revealed. An analysis is given of the influence of vortex formation and flow swirling processes on failures in NPP systems. It is shown that with a complex geometry of the channels of the pipe systems of the thermohydraulic tract and the reactor plant (RP), the unauthorized swirl arising in certain dynamic modes can lead to the effect of blocking the flow caused by the swirl flow crisis. It has been established that the phenomenon of the crisis is accompanied by the generation of low-frequency acoustic vibrations and large pressure losses required to form a recirculation flow zone, which prevents the flow of fluids in complex channels of the nuclear power plant. In the presented work, the manifestation of a swirling flow crisis is considered by examples of modeling the processes of hydrodynamics and heat transfer in the channels of steam generators and the pressure compensation system of transport nuclear power plants. It is shown that the generation of stable vortex formations in the elements of the NPP equipment of the integral type can be directly related to the mechanism of excitation of hazardous vibroresonance effects. Methods for improving the design of pipe systems of steam generating plants are proposed to increase their thermal-hydraulic efficiency and vibration resistance.

Authors: Sultan Fazal Mohamed Mohamed , Karuppannan Gunasegaran , Rumpod Justin
Published: January 2022

This study aims to identify the correlation between the instructional leadership practices by the headmasters with the level of performance and achievement of schools in Malaysia. A total of 141 respondents comprised of senior assistants of primary schools were examined. Respondents' perceptions of instructional leadership practices by the headmasters were gained using a set of questionnaire that was modified from the Principal Instructional Management Rating Scale (PIMRS). Descriptive statistical analysis was used to obtain the mean score, percentage, and standard deviation of the instructional practices. At the same time, ANOVA test was applied to obtain the perceptions from demographic factors and Pearson Correlation to measure the relationship between the instructional leadership and the schools’ performance that is based on band measurement. The findings show that the level of instructional leadership practice is high, with a mean of 4.24. Band 1, 2, 3 and 4 schools each have min of 4.37 4.23, 4.23 and 4.05 respectively. Pearson correlation analysis shows that there is a weak negative correlation between the headmasters’ instructional leadership practices level and the performance of the schools (r = -0.210). Thus, findings conclude that the level of instructional leadership practices among headmasters in primary schools is high and has a weak negative relationship in-term of schools’ achievement.
The Dialectic of Food Swamps and Clean Food
Authors: Lozon Emma
Published: January 2022

Applying an ecological rhetorical approach, this article examines the online circulation of arguments about food choice in two seemingly disparate sites: clean, medicinal food rhetoric and the rhetoric of “food swamps.” Studying snack food conglomerate Mondelez International’s “Mindful Snacking” campaign in juxtaposition with clean eating brand Sakara Life’s “made-for-Instagram” marketing materials demonstrates how clean, medicinal food texts emerge as acts of communicative resistance to the normalization of fast and processed food, yet slip back into the same meritocratic logic emphasizing individual responsibility and ultimately reproduce the ideological conditions that maintain inequitable access to healthy food. This article concludes with suggestions for disrupting and transforming the pervasive individualizing frameworks of food choice that locate health and diet concerns in the individual as opposed to the wider political, economic, and environmental context.

Die Jahre der wahren Empfindung
Authors: Böttiger Helmut
Published: January 2022

Die Literaturgeschichte der 70er Jahre, faszinierend und facettenreich als Zeit- und Gesellschaftsgeschichte erzählt.

Helmut Böttiger zeichnet ein differenziertes, bunt schillerndes Bild der politischen, kulturellen und literarischen Prozesse dieses Jahrzehnts zwischen Aufbruch und Desillusionierung. Mit Peter Schneiders Erzählung »Lenz« diagnostiziert Helmut Böttiger der Literatur am Beginn der siebziger Jahre eine »plötzliche Verunsicherung«. Er spürt ihren Wurzeln und Konsequenzen in den Werken der wichtigen Autorinnen und Autoren nach.

Hermann Peter Piwitt, Bernward Vesper, Christoph Meckel stehen ihm für die Auseinandersetzungen mit den Nazi-Vätern. Ein anderes Kapitel widmet sich einem neuen Ton, den Autorinnen wie Karin Struck und Verena Stefan in die Literatur gebracht haben. An Nicolas Born und Rolf Dieter Brinkmann erkennt er symptomatische Sprechweisen in der Lyrik dieser Jahre.

In einzelnen Kapiteln setzt Böttiger sich mit literaturhistorischen Zusammenhängen, den individuellen Korrespondenzen und Unterschieden einzelner Werke auseinander, sie sind gewidmet: Ingeborg Bachmann, Peter Handke, Wolf Biermann, Franz Fühmann, Christa Wolf, Fritz Rudolf Fries, Peter Weiss, Manfred Esser, Guntram Vesper, Peter Rühmkorf, Thomas Bernhard, Uwe Johnson, Arno Schmidt, Wilhelm Genazino, Eckhard Henscheid und Jörg Fauser sowie den Nobelpreisträgern Heinrich Böll und Günter Grass. Ein Kapitel widmet sich den neu entstandenen (und oft bald eingegangenen) Alternativzeitschriften, Verlagen und Buchhandlungen, ein anderes speziell dem Wagenbach-Rotbuch-Komplex.
Präsenzeffekte

Published: January 2022

Interdisziplinäres Close-Reading eines Kulminationswerks des spanischen Barock hinsichtlich ästhetischer Verfahren der Präsenzerzeugung.

Verfahren der Präsenzerzeugung berühren zentrale Aspekte der Wirkung und Funktion von Bildern. Insbesondere im religiösen Kontext wird Bildern das Vermögen zugestanden, durch unterschiedliche Ausprägungen von Präsenz einen Dialog zwischen jenseitiger und irdischer Sphäre herzustellen.

Vor diesem Hintergrund widmet sich das Buch der Inszenierung der wundertätigen Hostie von Gorkum, genannt Sagrada Forma, in der Sakristei des Real Monasterio de San Lorenzo de El Escorial. Der Clou der hochkomplexen Altarbildanlage (1684-1690) besteht darin, dass die Hostie, die zu den bedeutendsten Reliquien am Hof der spanischen Habsburger zählte, den größten Teil des Jahres den Blicken der Gläubigen entzogen war. Nur zweimal im Jahr wurde das berühmte Mittelbild Claudio Coellos mit der Darstellung Karls II. in Anbetung der Sagrada Forma auf »wundersame Weise« hinter dem Altar versenkt, um die Hostie der Verehrung durch den König preiszugeben. Von einer nahsichtigen Analyse des mehrere Bildmedien vereinenden Gesamtensembles ausgehend, eröffnet das Buch einen differenzierten Blick auf unterschiedliche Formen der Vorstellung von Präsenz.
The Imperative—and the Challenges—of Introducing a Citizen-Leader Development Program in an Undergraduate Liberal Arts Setting
Authors: J. Fratantuono Michael
Published: January 2022

Leadership, especially that associated with collaborative endeavors, is important for addressing emerging, increasingly complex challenges. That development is relevant to liberal arts colleges that are dedicated to educating generalists rather than specialists. The author maintains that such an education helps young people cultivate three sets of individual characteristics: values, capabilities, and aspirations. As well, it provides young people opportunities to become involved in a six-part iterative process intended to promote positive change. In spring of 2019, the author’s home institution Dickinson College launched a call for proposals from faculty, staff, and alumni that were consistent with the College’s mission and strategic priorities; and would strengthen its competitive position and deepen its relationships with stakeholders. Over a two-year period, the author played a central role in (1) helping shape a proposal originated by two alumni and (2) with several Dickinson community members, translating the proposal to an implementation plan. The efforts fell short; but the author learned lessons about such an endeavor. A well-conceived plan must find the areas of intersection among the interests of key stakeholders. A plan must be of scale that enables organizational practicality and financial feasibility. Successful implementation hinges on the components of good collaborative leadership highlighted above. Explanation and launch of a plan must create excitement among sponsors and potential beneficiaries.
Complementary Treatment for Women with Breast Cancer: A Psychomotor Therapy Approach
Authors: Veiga Guida , Duarte Santos Graça
Published: January 2022

Women with breast cancer face a diversity of physical, psychological, and social changes that affect their health and well-being across the different stages of the cancer journey, including treatment and survival. Moreover, breast cancer often results in greater distress than any other neoplasm, challenging women’s body, identity, and quality of life. Given the multiplicity of mind–body related problems that may confront women with breast cancer, psychomotor therapy is a valuable therapeutic approach for these women. This chapter presents a framework based on psychological and neurobiological research to understand how a mind–body approach as psychomotor therapy improves cancer-related symptoms, readjusts body schema, body image and identity, thus contributing to women with breast cancer’s health and well-being. Two intervention programs, uniquely designed as a complementary approach of medical care for women in the treatment and survival phases, are also described. The impact of these programs on health and quality of life indicators of women with breast cancer are also presented.

The most pressing concern in the world since independence has been producing enough food to feed an expanding population. The mix of high-yielding production techniques has helped the globe to generate a food surplus while also raising worries about soil health and environmental pollution. Though, scientists and policy makers are rethinking agricultural systems that rely heavily on biological inputs. Organic farming can provide high-quality food without compromising the health of the land or the environment; nevertheless, it is unclear if large-scale organic farming would be able to feed world’s vast population. Adoption of this emerging approach “organic vegetable farming” plays a vital role in development of agricultural sustainability through avoiding indiscriminate use of synthetic chemicals. There are numerous organic sources for organic vegetable farming but various type of composts (especially vermi-compost) and biochar are most famous among all other organic sources as they improved soil healthy and vegetables productions through improving soil physico-chemical and biological attributes. In addition, demand and prices of organically produced vegetables are much higher in market and evidence showed that organically grown vegetables are enriched with nutrients and safe for consumption because of their less exposure with residues of in-organic pesticides.
Postharvest Processing, Value Addition and Marketing of Mushrooms
Authors: Prasad Thakur Mahesh , K. Singh Harvinder , Shekhar Shukla Chandra
Published: January 2022

Mushrooms are macrofungi having a higher content of water (80–90%) and multinutrients. The presence of various phytochemicals, enzymes, primary metabolites and secondary mycometabolites results in poor shelf-life, quick deterioration, and huge postharvest losses (30–35%). Fresh mushrooms are short lived (1–8 days). Value chain management is thus necessary from the production to its harvest to meet the food and nutritional requirements. Every effort was made to extend the shelf-life of mushrooms for either short period or long period of storage. Washing or pretreatment, packaging, transport and marketing were some of the important standardized techniques for short-term storage of mushroom. On the other hand, drying, pickling and steeping preservation methods were some other techniques to extend the shelf-life of mushroom for a longer period of time during storage. Value addition of mushroom enhanced the quality and addressed the demand for ready-made or ready-to-make food products. Fresh/dry oyster mushroom in various proportions (5–10%) was used to prepare mushroom paratha, mushroom suji, mushroom sandwich, mushroom chakli, mushroom seb, mushroom-based biofortified wheat flour, mushroom-based papad, nuggets, mushroom bijoura, biscuits, etc. Several mushroom-based, value-added products like Royal Oyster Capsules were prepared by Self Help Groups women at Kapadah (Kabirdham).
Impact of PCBs, Furan and Dioxin on Hepatocarcinogenesis
Authors: Helal Mohamed , Ghanem Sara , El-Sikaily Amany
Published: January 2022

Stockholm Convention defined polychlorinated biphenyls (PCBs) as a group of persistent organic pollutants (POPs) such as dioxin/furan, dichlorodiphenyltrichloroethane, polychlorinated biphenyls, polychlorinated dibenzo-p-dioxins, aldrin, polychlorinated dibenzofurans and organometallic compounds (such as organotin and organomercury) which share the same characteristics of being persistent, bioaccumulative and toxic and can travel long distance through various media. They have diverse health impacts with different underlined molecular mechanisms. Recently, PCBs were referred as potent carcinogens with persistent existence in the environment. As the liver is the organ of detoxification, it is the major target organ for toxic effects induced by environmental contaminants, including PCBs. PCBs, furan and dioxin exert their hepatocarcinogenic effect through different mechanisms such as induction of oxidative stress, an increase of reactive oxygen species (ROS), mutagenic induction to oncogenes and epigenetic alteration to hepatic cells. In this chapter, we will provide an updated overview about PCBs, furan and dioxins, their impact on liver cancer initiation and progression on various in vivo and in vitro systems and its underlined molecular mechanisms. Also, a special emphasis will be directed to highlight zebrafish as in vivo model system to analyse the hepatocarcinogenic effect of these pollutants.
Antibacterial Activity of Plant Polyphenols
Authors: Satchanska Galina
Published: January 2022

This chapter focuses on methods of polyphenol isolation and on the antibacterial activity of different polyphenols found in herbs, spices, fruits and vegetables. Polyphenols are secondary metabolites which protect plants from different pathogens, such as viruses, bacteria, fungi, insects, and herbivores. Currently, about 9000 polyphenols found in more than 480 plants are known. Their amount fluctuates across different species and varieties. This chapter describes conventional and novel methods for extraction, the influence of the type of solvents, solvent concentration and temperature on the yield. The highest yield is obtained at 70% of methanol and ethanol, and at 90% of acetone. Extraction at 80°C leads to higher amounts of polyphenols than extraction at 100°C. Polyphenols are usually metabolized in the human liver but can also remain unaffected as they pass through the gastrointestinal tract. The main location for their uptake is the colon. They exhibit a wide range of antibacterial activity against Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus epidermidis, Klebsiella pneumoniae, E. coli, Listeria monocytogenes, Acinetobacter sp., Proteus sp., Micrococcus sp., and Bacillus sp. All these plants, rich in antimicrobial polyphenols, represent a promising and powerful source of highly effective novel antibacterial substances in the current era of ubiquitous antibiotic resistance.
Molecular Mechanisms of Glucose Uptake Regulation in Thyroid Cancer
Authors: Heydarzadeh Shabnam , Asghar Moshtaghie Ali , Daneshpour Maryam , Hedayati Mehdi
Published: January 2022

Common capabilities of thyroid malignant cells are accelerating metabolism and increasing glucose uptake to optimize energy supply for growth. In tumor cells, keeping the power load required for cell survival is essential and glucose transporters are capable of promoting this task. GLUT-1 and GLUT3 are promising goals for the development of anti-cancer strategies. The lack of oncosuppressors has dominant effect on the membrane expression of GLUT1 and glucose uptake. Overexpression of hypoxia-inducing factors, in thyroid cancer, modulates the expression of some glucose transporter genes. Although the physiology of the thyroid gland has been excellently explained, metabolic regulation in thyroid cancer is inevitable. In this section, we investigated the proliferation pathways of pivotal regulators and signal molecules around GLUT regulation in thyroid cancer, including PTEN, p53, MicroRNA, iodide, BRAF, HIF-1, PI3K-Akt, TSH, c-Myc, and AMPK. Impaired energy regulation and cell metabolism are the most critical symptoms of most cancers. As a result, understanding the mechanisms of glucose transport in the normal and pathological tissues of the thyroid may be very crucial and offer tremendous insights into the science of analysis and remedy of thyroid disease.

TP53 codes tumor protein 53-p53 that controls the cell cycle through binding DNA directly and induces reversible cell-cycle arrest. The protein activates DNA repair genes if mutated DNA will be repaired or activates apoptotosis if the damaged DNA cannot be fixed. Therefore, p53, so-called the “guardian of the genome,” promote cell survival by allowing for DNA repair. However, the tumor-suppressor function of p53 is either lost or gained through mutations in half of the human cancers. In this work, functional perturbation of the p53 mechanism is elaborated at the breast, bladder, liver, brain, lung cancers, and osteosarcoma. Mutation of wild-type p53 not only diminishes tumor suppressor activity but transforms it into an oncogenic structure. Further, malfunction of the TP53 leads accumulation of additional oncogenic mutations in the cell genome. Thus, disruption of TP53 dependent survival pathways promotes cancer progression. This oncogenic TP53 promotes cell survival, prevents cell death through apoptosis, and contributes to the proliferation and metastasis of tumor cells. The purpose of this chapter is to discuss the contribution of mutant p53 to distinct cancer types.
Incidence and mortality of malignant tumours in Serbia: A comparative analysis
Authors: Miljuš Dragan
Published: January 2022

After cardiovascular diseases, malignant tumours are the second leading cause of death across Europe. Given that Europe has a quarter of all cancer cases and less than 10% of the world's population, it is obvious that cancer poses a huge burden in the entire European region. A comparative analysis of the incidence of malignant tumours in Serbia and European countries in 2018 showed that men in Serbia most often suffered from malignant tumours of the prostate, lungs and bronchus, colon and rectum, while in women, malignant tumours were most often localized in the breast, lungs and bronchus, colon and rectum. Women in Europe most often suffered from malignant tumours of the breast, colon and rectum, and lungs and bronchus, while they most often died from the same tumours as the women in our country. Compared to the inhabitants of the European region, the population of Serbia has a higher incidence of morbidity and mortality from all leading cancers; exceptions can be observed in the structure of new patients with malignant prostate tumours, women with newly discovered breast cancers and men who died from liver cancer. For the majority of malignancy sites, the risk of cancer in Serbia is estimated as "moderate", and "low" for malignant prostate tumours. However, the observed increase in incidence for the most common malignancies could, in the next two decades, bring Serbian citizens into the ranks of European countries with a high risk of disease. Throughout Europe, the burden of cancer puts pressure on national health and social protection systems, state budgets and affects productivity and economic growth. National campaigns for health promotion and prevention of risk factors that are responsible for the occurrence of the most common malignant tumours and other non-communicable diseases, early detection and implementation of screening programs for malignant tumours, are the basis of the cancer control strategy, both in the old continent as a whole, and in Serbia.
New Extended Life Water-Lubricated Bearings, Using a High Performance Polymer Alloy
Authors: Orndorff Roy L. , Sheppert Richard V.
Published: January 2022

There is an urgent need for new, longer-lived cost-effective water-lubricated marine rudder and main propulsion shaft bearings. This paper describes a new bearing design, called Super Demountable, which promises to fulfill the need to exceed 15 years life by reducing bearing and shaft wear. The new bearing makes use of a new polymer alloy (NPA) that exhibits low wear itself and also near. zero shaft wear in abrasive-laden water. Wear of NPA and the friction torque are both reduced when the radial load is increased, resulting in L/D ratios of 2 or less. Rubber staves lock the NPA load-carrying staves in place in the new bearings, resulting in simplified (lower cost) housings.
Practical Developments in Propeller Shaft Design in RN Warships

Published: January 2022

LDV phase sampling technique is developed and adopted for the analysis of the flow upstream and behind a four blade, highly skewed installed propeller, for the case of a twin screw ship model in a large circulating water channel. The implemented technique allows the reconstruction of the 3D flow field for each revolution angle in transversal planes located as close as possible to the blade trailing and leading edge. The main features of the propeller installation are highlighted as well as the strong and complex interaction of the propeller with the hull wake, especially in the brackets region.
Ventilated Waterjets for High Speed Ships
Authors: McMahon J. F. , Dai C. M. , Gowing S. , Lin G. , Peterson F. P.
Published: January 2022

A ventilated waterjet (VW) is similar to a conventional waterjet with a fully submerged inlet region. However, the exit of a VW is partially submerged and the impeller blade is designed for ventilating conditions. The partially submerged exit provides a natural supply of air for ventilating the blade surfaces under most operating conditions. A VW can be used for high-speed vessels where traditional propulsors fail to perform due to cavitation limitations. It also can address some of the shortcomings typical of super cavitating or partially submerged propellers. The 24" water tunnel at the David Taylor Model Basin was modified to accommodate the testing of a VW. A stock surface piercing propeller with trimmed blade tips was tested in the ventilating mode and the results compared with a modified version of a Propeller Unsteady Force computer program. The general operating characteristics of a VW were identified in the 24" water tunnel tests. The results indicate that a VW could have better-powering performance over a wider speed range as compared with either super cavitating or surface-piercing propellers.

Shaft Alignment Optimization With Genetic Algorithms
Authors: Sverko Davor
Published: January 2022

A solution to the shaft alignment problem is a set of prescribed bearing offsets that ensure an acceptable load distribution among the shaft-supporting bearings. Acceptable load distribution implies not only all positive bearing reactions under all operating conditions of the vessel but also an acceptable relative-misalignment between the shaft and the bearing. In a marine environment, the difficulty is not in finding a single suitable solution to the above criteria, but rather in defining the optimal set of solutions capable of accommodating the extreme bearing disturbances - resulting mainly from hull deflections and thermal deviation. As the problem is stochastic, with an infinite number of satisfactory bearing offsets, it is appropriate to apply the Genetic Algorithm (GA) optimization procedure to search for the optimal set of solutions, rather than rely on the plain trial and error approach or some of the step-by-step conventional search algorithms. With an ability to conduct a parallel search throughout the solution space, the GA is particularly well suited for the problem at hand, as it has the capacity to simultaneously provide multiple sets of bearing offsets that satisfy loading conditions at bearings.
The Preliminary Design of Advanced Propulsors
Authors: Kerwin J. E.
Published: January 2022

Potential propulsors for current applications may vary in complexity from traditional open propellers to podded propulsors, multiple blade-row ducted units, and waterjets. In the past, the lifting-line theory has been an effective tool in establishing the principal characteristics of an optimum propeller design. Similarly, turbomachinery through-flow theory has been effective in preliminary estimates for internal flow devices such as waterjets. What is currently lacking is a single, unified approach that can be used for a wide range of propulsor types. This paper presents a possible solution to this problem, based on recent experience in detailed design methods based on coupling lifting surface theory with axisymmetric RANS/Euler solvers. In the present method, lifting-line representations of the blade rows are coupled with an axisymmetric Euler/Boundary Layer solver to provide preliminary estimates of propulsor performance.
Application of Micro-genetic Algorithm (µGA) to the Optimal Design of Hydrofoil and Marine Propellers
Authors: Karim Mashud
Published: January 2022

This paper presents results from the application of the genetic algorithm (GA) technique to the design optimization of hydrofoil and marine propeller incorporating the potential-based boundary element method (BEM). Although larger population size as implemented by simple genetic algorithm (SGA) could find the optimal individual after a fewer number of generations than smaller population size, it is penalized by a longer amount of time to evaluate fitness in every generation. An investigation is, therefore, conducted in this research to implement micro genetic algorithm (μGA) with a very small population, and with simple genetic parameters, in order to achieve faster convergence to better solutions from generation to generation. The technique is applied here to optimize hydrofoils of different plan forms, e.g., rectangular, elliptical, trapezoidal etc. Firstly, the hydrofoil design parameters, such as angle of incidence, maximum thickness, and camber ratios, aspect ratio, taper ratio, angle of sweep, etc. are initialized randomly and the generated hydrofoil is analyzed by potential based boundary element method. GA then updates the design parameters over generation after generation and finally, finds an improved hydrofoil of maximum lift-drag ratio or minimum drag coefficient satisfying some design constraints. An improved blade or hydrofoil section is also designed by GA satisfying some design constraints. Finally, the technique is applied to the optimum design of marine propeller. In this study, μGA is found a useful and prospective tool for the design optimization of hydrofoil due to its faster convergence.

Aims: Advanced practice providers are a rapidly growing sector of the health-care field. Despite their relatively new place in the medical establishment, these providers are held to high standards of education, practice, and communication skills. However, the communication needs of these practitioners are somewhat different than those of nurses or physicians. These skills are even more necessary in specialized fields where providers frequently are involved in discussions of prognosis, goals of care, and end of life. Design: This was a mixed-methods study. Methods: We completed a needs assessment of communication skills for advanced practice providers at a large cancer center in the northeastern United States from June to July 2017. Results: Participants were confident in their skills across several areas of communication, but also endorsed the need for communication skills training, particularly for challenging interactions with patients and families. Advanced practice providers described many challenges similar to those descried by other health-care providers, including general communication skills problems, navigating team dynamics, and goals-of-care planning. However, participants also endorsed communication skills needs specific to their field, including certain patient-centered challenges, perceived/real limitations of their role, serving as the “middleman,” and understanding the advanced practice provider’s role. Conclusion: Given the general and unique communication challenges advanced practice providers in oncology face, we conclude with recommendations for further institutional and educational changes to better address these needs.
A Case of Lung Adenocarcinoma Response to Alectinib Harboring a Rare EML4-ALK Variant, Exon 6 of EML4 Fused to Exon 18 of ALK

More than 20 types of ALK fusion variant subtypes have been identified, including different fusion partner genes or EML4-ALK fusions with different breakpoints. However, different ALK fusions show different sensitivities to ALK-tyrosine kinase inhibitors (ALK-TKIs) and the emergence of rare fusions brings great challenges to the target therapy in clinic. We report a rare EML4-ALK (E6;A18) fusion in a patient with lung adenocarcinoma that responded well to alectinib. This is the second case of this rare variant reported but the first report of response to an ALK-TKI. This evidence is the first to show that alectinib may be effective for this rare fusion type of non–small cell lung cancer, and these findings have important implications for drug selection in patients with this subtype. Further studies are needed to understand the function of this variant.
Le rapport au travail : mise en lumière de l’agentivité des jeunes en situation de vulnérabilité au Québec et en France

Work plays an important role in the lives of both societies and individuals. It serves as both a means for
social integration and a source of identity, notwithstanding historical contexts marked by precarious
employment. Whereas much international research and many comparative studies have addressed
young people’s relationship to work, the existing literature tends to paint a rather uniform picture of
youth. This article begins with a focus on the unique aspects of the relationship to work among vulnerable
youth, which leads to an exploration of the processes by which these individuals develop agency.
Coupled with inductive qualitative analysis, the systematic international perspective provided by
interviews conducted with vulnerable youth (dropouts, immigrants, Indigenous persons, rural residents,
and overqualified individuals) in Quebec and France shows that labour market participation not only
remains important to these youth but constitutes a hub around which their lives acquire structure and
meaning. They experience inactivity very negatively and express strong criticism of social assistance.
Although vulnerable youth are acutely affected by material insecurity and often cite the desire to earn
money as a reason for working, financial considerations remain complex by involving a variety of
dimensions. Finally, despite the hardships they experience, young people tend to describe the labour
market in pragmatic and optimistic terms.
Developmental and educational potential of using an authentic feature film in the process of teaching foreign language
Authors: Makarichev Feliks Vyacheslavovich
Published: January 2022

 The subject of this research is the use of an authentic feature films in the process of teaching English language. Based on the analysis of theoretical material, the article covers the questions related to the use of films during the classes in higher educational institutions, since despite the old-established practice of using audiovisual means, there is yet no universal methodology for working with films. The author offers to organize classes based on watching the “American Beauty”, which would enrich the vocabulary, analyze various situation of verbal and nonverbal communication, give representation on the national peculiarities of language behavior. The authentic feature films have been largely used in the process of teaching foreign language. However, more than ever before the use of audio and video materials has become a strict necessity for the effective teaching of students of various specialties. The command of a foreign language is not only the ability to conduct verbal communication, but establish the cross-cultural dialogue that ensures effective communication. Therefore, competent linguistic, culturological, and country-specific training is required. The effectiveness of using feature film in the learning process is determined first and foremost by the peculiarities of cinematographic art, which can strongly affect the audience. This is achieved by combining video sequence and sound (including music). Therefore, the audience receives a visual representation on the place of the ongoing events, appearance of the characters, analyze the specificities of nonverbal means of communication, and determine their impact upon the content of communication and its results. The author’s experience of conducting film analysis with the students of non-philological specialties indicates students’ interest in such activities, both at the lectures or doing homework, and thus high academic performance. 
Analysis of the methods for competing recursion in recursive riles in the logic programming language Prolog
Authors: Zdor Dmitrii Valer'evich , Gornostaeva Tat'yana Nikolaevna
Published: January 2022

One of the developing trends in programming is the logic programming associated with the implementation of tools for creating artificial intelligence. One of such programming languages is the nonprocedural declarative logic programming language Prolog. This article is dedicated to the use of recursive rules in Prolog software. The goal of this work lies in analysis of the methods for completing recursive calls in recursive rules, as well as in explication of the use of such methods on the examples of programs with recursion. The author explores the specialized literature on the topic, generalized and systematizes the data, as well as tested the programs and the progress of their implementation. Recursive rule in the Prolog software sets an infinite cycle of repetition of predicates. For completing the recursive cycle, it is necessary to set a condition within the program that would end the cycle. The article examines the variants of organizing recursions with the completion of infinite cycle. The examples used in the article allows using them as the basis for programming in language Prolog for solving similar tasks. The acquired results are valuable for further development of the use of recursive predicates in logic programming languages.
Bashkir cinematography as a phenomenon of national Culture
Authors: Baiturina Diana Uralovna
Published: January 2022

This article examines the milestones in the development of cinematography as a phenomenon in Bashkortostan. The author traces the path from the emergence of very first films to the present state of local film production in the republic. Research methodology leans on the methods of systematization and analysis of scientific literature, written and cinematographic sources, historical-typological (analysis of the historical and cultural grounds of Bashkir cinematography), interpretation of written and cinematographic material. The peculiarities of the establishment and development of Bashkir cinematography are revealed. The theoretical importance of this article lies in systematization of knowledge and description of the ethnocultural characteristics of the development of cinematography in the context of Bashkir cultural field. Cultural tradition as an example that is being reflexively used by people within the framework of a particular culture for solution of life tasks underlies the national cinematography. The models of lifestyle and perception of the world in a given cultural era are realized in the national cinematographic works and represent cultural paradigm of the nation. The author notes the ethnic peculiarities of the development of the phenomenon of cinematography in the region. Prevalence of the elements of traditional national culture (plotlines and images) in the films determines the peculiar nature of Bashkir cinematography and impacts the ethnocultural identity of the recipient. The scientific novelty lies in revealing the historiographical and culturological aspects of Bashkir cinematographic works, as well as outlining its role in modern art culture. The study was conducted on the basis of semiotic and interpretational methods of art history analysis.
