“He made me fall at the feet of a woman”: Masculine Anxieties and Dysfunctional Romance in Tamil Cult Film Subramaniyapuram (2008)
Authors:   Assistant Professor in the Department of Humanities and Social Sciences in the Indian Institute of Technology Madras., A Divya
Published: June 2021

Tamil Cinema is “one of India’s largest, most prolific and increasingly significant cinemas” (Velayutham 2008, pp.1-2). Madurai genre in Tamil films is popularly known as 3M films (Murder, Mayhem and Madurai) (Damodaran Gorringe 2017, p.9). Subramaniyapuram (Sasikumar, 2008) is a Madurai film that attained cult status in both the Indian states of Tamil Nadu and Kerala since its release in 2008. A collection of essays on Subramaniyapuram edited by anthropologist Anand Pandian was published in 2013, a rare honour to be bestowed on a Tamil film in recent times. Significantly, the film’s problematic gender narrative—especially the entangled relation between the romantic plot and the masculine “plots”—is not the central subject of exploration of any of the essays in this edited collection, nor has it been discussed in depth in any critical discourse on the film so far. In this article, using Laura Mulvey’s theoretical lens as a point of departure, I argue that the female identity is crucial to the narrative functioning of the various plots of Subramaniyapuram. The film’s ultimate narrative desires, I illustrate, are in affirmation of masculine supremacy, hegemonic masculinity, and the women as femme fatales.
The Processes of Dehumanization in the Encounter with the Other: An Exploratory Study During the Lynching of African Americans in the United States, 1882 – 1968
Authors:   University of Turin., Corvino Giovanni B.
Published: June 2021

The dehumanization processes represent a failure in the attribution of thinking skills to other human beings. Based on ethnicity, gender, sexual preference, and nationality, social prejudices are reinforced in basic neurocognitive structures. Still, their manifestation is conveyed by personal goals and normative beliefs, which develop in an environment of a dyadic relationship or intergroup contexts. Therefore, this paper aims to peruse the perspectives for a theory of dehumanization, supporting them with neuroscientific research on the neural basis, and exploring the forms of dehumanization that African Americans suffered when they were victims of lynching in the United States.
Review article: The Politics of Gender Hybrid Representation of Delhi
Authors:   Department of English, St. Xavier’s College, Jaipur, Rajasthan, India., Rawal Shruti
Published: June 2021

The growth of the metropolitan phenomenon has resulted in the emergence of new power centres in all the countries of the world. These cities have geographical, political and economic significance. The narratives of these cities have been captured by the writers for centuries in their fictional and non-fictional work. The research intends to focus on the representation of the city of Delhi in two prominent works: Khushwant Singh’s Delhi: A Novel and Arundhati Roy’s The Ministry of Utmost Happiness. Both the texts are located in the city of Delhi and have a prominent transgender character at its core and the study aims to understand the writer’s intent and manner of drawing similarities between the city and the character. It also proposes to explore this hybridity of gender as a deliberate tool to represent the city of Delhi. The failure of anyone binary to capture the essence of the city and the advantage of the androgynous approach will be discussed in the paper. It will also endeavour to understand how the phenomenon of cities has led to the creation of spaces that promote hybridity.
Reframing Reproduction in Vernacular Periodicals: A Study of Contraception in Late Colonial Bengal
Authors:   M. Phil scholar at the Department of English, Jadavpur University., Bhattacharya Ayana
Published: June 2021

With the emergence of the thriving literary public sphere around the close of the 19th century across colonial India, the issue of birth control was being debated in various magazines by economists, sexologists, doctors and members of women’s organizations. The discussions on reproductive rights of women and dissemination of contraceptive information published in various vernacular periodicals can be situated within a network of other contemporary discourses on “economizing reproduction” that were gaining visibility around this time. The present paper would like to explore the perceptions of women’s reproductive body at the beginning of the 20th century that were being forged through coalescing narratives on bourgeois norms of obscenity (aslilata?), biopolitical concerns of an emerging nation state in the last throes of anti-colonial struggle, and various takes on (heteronormative) interpersonal relationships between future citizens. It is within this specific context that I would like to examine articles on birth control published during the early 1930s in the ‘self-styled’ Bengali women’s magazine Jayasree? launched by revolutionary leader Leela Nag. By situating the opinions voiced by the men and women writing in the pages of this literary periodical vis-à-vis contemporary intellectual trends of birth control movement in India, this paper seeks to study the interactive textual ecosystem within which the writers and readers (the implied future authors) of Jayasree? were functioning.
Infidelity to True Story and Novel: Locating the Auteur in Rituparno Ghosh’s Dahan
Authors:   Assistant Professor, School of Social Sciences and Languages (SSL), Vellore Institute of Technology (VIT), Chennai Campus, Tamil Nadu, India, Mukherjee Akaitab
Published: June 2021

Rituparno Ghosh (1961-2013), a celebrated Bengali film director who started making films in 90s, often borrows plots from literary and other cultural narratives. The essay aims to explicate Ghosh’s early film Dahan (1997) which is an adaptation of distinguished Bengali novelist Suchitra Bhattacharya’s novel with the same title. Bhattacharya’s novel is influenced by the real incident in which a couple was harassed by four youths at Tollygunge Metro Station in Kolkata on 27th November, 1992. The film also acknowledges that it is indebted to the true story. The essay explicates the adaptation of the two sources by the auteur. It examines the duplication of authorial concerns in this adaptation while following the narratives of two texts. Ghosh remains unfaithful to the literary text and the cultural memory of the true story to establish his authorship. As Ghosh’s films portray the middle-class women in a patriarchal society, following Janet Staiger’s reconsideration of the theory of auteur in the context of queer movement and identity politics in the 1970s, the essay argues that the performance of infidelity to the literary and true story to establish authorship is auteur’s “technique of the self”.

Published: June 2021

In 2018, when Nandini Krishnan decided to write a book on trans men of India titled ‘Invisible Men’, perhaps she expected great accolades. After all, she was raising a topic that was relegated to the periphery of peripheries, an identity that often went astray in translation. But was the intent enough to write something impactful and honest? At the same time in Indian Cinema, Akshay Kumar geared up for a stereotyped role as a trans woman. What’s the connecting dot between these two? They ended up being nothing but highly skewed queer representations by cis-folks. Meanwhile, an alternative movement was brewing on social media as Alok Menon narrated poems of subversion, dressed as a challenge to everything heteronormative. The current paper aims to examine these voices of subversion, of trans narratives, as formed and catalyzed on social media and across various mediums of general discourses. The paper would also explore the rise of trans narratives in literature with special reference to ‘Me Hijra, Me Laxmi’ by Laxminarayan Tripathi and ‘A Life in Trans Activism’ by A. Revathi. Both exploratory and descriptive research methods are used for deriving the theoretical analysis from primary and secondary sources.

Published: June 2021

The recent advances of the digital era invoke an array of new media for communication. This impressive feat of technology purveys a wide range of new affordances to communication unviable in print. The new media affordances of the electronic and the digital have impacted the creative literary compositions, providing innovations in contemporary literature. Postmodern literature being the initiation of experimental works has strived to reinvent the affordances of literary fiction. It has now advanced into resorting to digital technological affordances to maximize narrative inventiveness. Lance Olsen’s “10:01”, a postmodern novel adapted as hypertext fiction, is an exemplar of such feat. This research examines the literary affordances of the chosen text in print and its hypertext adaptation within the framework of affordance theories. The study unveils the inlaid new media aesthetics and viabilities of the digital in relation to the traditional medium of print by focusing on affordances. The paper asserts the significance of theorizing the aesthetics involved in digital textuality by holding print and electronic literature at the intersection. This study aims to establish the shift in literary analysis paradigms of text due to the emergence of New media.
Agency and Self Expression: Fan Writing as Life Writing
Authors:   Assistant Professor of English and Cultural Studies, Christ University, Bengaluru., Abraham Renu Elizabeth
Published: June 2021

Fans, fandoms and fan activities have been part of every culture from time immemorial. Homer’s epics, Plato’s work all could be considered in a broad sense as belonging to the larger domain of fan activity or fan ‘art’ as they are termed in modern-day parlance. This paper examines India Forums a digital fan community based in India for audiences and fans of Indian television soaps/serials and attempts to understand how fanfiction and fan activities within this forum act as means of self-expression and enable its fans to develop a sense of agency that is indigenous to the space in itself. This community is predominantly populated by women or ‘gender anonymous’ and function as a space that allows fans to construct their own voices, identities and thereby agency, which is most often restricted to that space alone. The fans though not subaltern, in the technical sense of the term, as they belong to the urban space, have access to a computer and can read, write and speak English although not fluently, are still urban middle-class women who have been spoken for and never spoken themselves; and India Forums enable these unheard voices to be heard. This reading analyses the dynamics of this agential space, the politics of this agency and argues that all fan writing within this space functions as life writing within a hypertextual metaconversational paradigm which is not necessarily reflective of traditional forms of life writing using notions of revisionist Freudian psychoanalysis and paradigms of life writing.

The formation of social memory is an important component of the state humanitarian strategy. It acquires special significance in the conditions of postmodern transformations of a transitional society, which directly relate to the functioning of the political system. Thus, the process of democratic transition is becoming an undeniable and peremptory reality. The necessity for liberal political and economic reforms is also not much controversial. With this state of affairs, ideological discussions acquire a retrospective direction, their subject is not the search for development models for the future, but the construction of models for assessing the past. The novelty of the study is determined by the need to assess social participation on the part of both individual and public entities. The authors classify not only the population as social entities but also the carriers of the cultural code, who may belong to extraterritorial groups. The article shows that social memory can also be considered as a method of socio-economic development of a territory, and in order to achieve political objectives by individual groups of capital. The practical significance of the study is determined by the possibility of structuring social memory and building on this basis socio-economic strategies for the development of a sustainable society.

Recent Advancements for the Management of Pancreatic Cancer: Current Insights
Authors: Ali Naureen , Srivastava Nimisha
Published: June 2021

One of the most fatal forms of cancer includes cancer of the pancreas And the most rapid malignancy is observed in PDAC (pancreatic ductal adenocarcinoma). The high lethality rate is generally due to very late diagnosis and resistance to traditional chemotherapeutic agents. Desmoplastic stromal barrier results in resistance to immunotherapy. Other reasons for the high lethality rate include the absence of effective treatment and standard screening tests. Hence, there is a need for effective novel carrier systems. “A formulation, method, or device that allows the desired therapeutic substance to reach its site of action in such a manner that nontarget cells experience minimum effect is referred to as a drug delivery system”. The delivery system is responsible for introducing the active component into the body. They are also liable for boosting the efficacy and desirable targeted action on the tumorous tissues. Several studies, researches, and developments have yielded various advanced drug delivery systems, which include liposomes, nanoparticles, carbon nanotubules, renovoCath, etc. These systems control rate and location of the release. They are designed while taking into consideration characteristic properties of the tumor and tumor stroma. These delivery systems overcome the barriers in drug deliverance in pancreatic cancer. Alongside providing palliative benefits, these delivery systems also aim to correct the underlying reason for the defect. The following review article aims and focuses to bring out a brief idea about systems, methods, and technologies for futuristic drug deliverance in pancreatic cancer therapy.

Aims:

Erythrocruorin is considered for a potential application as a Red Blood Cells Substitute.

Background:

Nanostructured materials such as liposomes and polymeric materials have offered new
alternatives that allow the design of systems as potential substitutes for red blood cells.

Objective:

Functionalized liposomes fabrication and characterization.

Methods:

The liposomes manufactured with egg yolk lecithin prepared by the extrusion method were
functionalized with EfEc and stabilized with polyethylene glycol (PEG) by an absorption method.

Results:

The nanoplatform has a hydrodynamic diameter of 452.4 ± 24.56 nm; this size provides the
ability to avoid problems such as system extravasation, also presents stability (ζ-potential = -30. 06 ±
0.42 mV) and SEM micrographs show a semi-spherical morphology. Also, EfEc showed a peak of
fluorescence emission at 449 nm, which allowed us to observe the protein's presence on the surface
of the liposomes employing CLSM.

Conclusion:

In this work, we report the fabrication and characterization of liposomes with EfEc and
PEG on their surface. The nanoplatform exhibits physical-chemical characteristics that confer a potential
application as a substitute for red blood cells.
Method for measuring the azimuth of an aerial target for a meter-range radar
Authors: Ermoshkin V. I. , Shatkovsky S. B. , Shcherbinko A. V. , Fenyuk E. E.
Published: June 2021

The purpose of the study is to develop a new method that increases the accuracy of measuring the azimuth of an air target for stationary radars of the meter range of radio waves with a fixed antenna array and a small number of antenna elements. For this, the known methods are considered and their disadvantages are revealed. The new method proposed by the authors uses a digital radiation pattern with a fast Fourier transform after intra-pulse processing of signals from the receiving elements of the antenna array at a given frequency. To refine the azimuth, an inverse fast Fourier transform is used, followed by signal processing and repeated measurement for each target with a small step. Calculations and test results are presented. Comparisons of statistical estimates of the mean and standard deviation of azimuth measurement tests by various methods are presented. The scientific novelty and directions for further development of the topic with the use of the results obtained have been established.

Published: June 2021

Microwave integrated circuit (IC) design tends to become more efficient and less expensive which leads to emerging the circuit topology and layout synthesis software. In the paper we present a technique and an algorithm for microwave distributed amplifier (DA) automated synthesis based on requirements to linear characteristics. The technique feature is the using of active and passive element’s models for a chosen IC process. This allow the technique to generate circuit topology which can be manufactured using a given IC process. The proposed DA automated design technique work was demonstrated with preamplifier stage design for 20–30 GHz buffer amplifier MMIC based on the 0.25um GaAs pHEMT process of Svetlana-Rost foundry in Saint-Petersburg.

Published: June 2021

Objective: This study performed a literature review evaluating aspects of prevalence and motivations on the non-medical use of methylphenidate by medical students. Methods: We searched the Scopus, PubMed, SciELO, and Web of Science databases and the Google Scholar search tool using the keywords "Methylphenidate" and "Medical Student" and their correlates in Portuguese. A total of 472 articles were recovered, of which 24 were included for full reading and discussion after the application of the pre-established inclusion and exclusion criteria. Results: It was observed that the prevalence of non-prescribed use of methylphenidate ranged from 0.51% in Lithuania to 35% in Colombia. The main motivations reported for using the drug were academic outcomes improvement and increase in concentration during studies, although research shows no significant improvement in academic performance with the use of medication by healthy individuals. Conclusion: The non-prescribed use of methylphenidate presents a high and worrying frequency. Also, scientific studies questioning the use of psychostimulant medications for cognitive improvement by healthy students make the practice illegal and unfounded.

Objective: To identify motivational factors for the practice of physical exercises and their relationship with the quality of life (QoL)of women. Methods: A cross-sectional study, conducted with 48 women practicing exercise in gyms aged between 19 and 59 years and with a mean age of 39.4 ± 11.7 years. Exercise Motivations Inventory (EMI-2) and WHOQOL-Bref were used as instruments. The data were analyzed using the Kolmogorov–Smirnov tests, homogeneity of Levene's variances, independent t-test, and Pearson's correlation (p < 0.05). Results: Older women are more motivated to exercise for health rehabilitation. The youngest had a higher score in the physical domain of quality of life. There was a significant, positive, and weak correlation of the physical domain with weight control (r = 0.24), appearance (r = 0.33), a weak and negative correlation of the physical domain with health rehabilitation (r = -0,33), a positive and weak correlation of the social domain with physical conditioning (r = 0.23), and a positive and weak correlation of the general QoL score with weight control (r = 0.23). Conclusion: The main motivational factor for the practice of physical exercise was preventing diseases, especially in the group of older women. Younger women had a better perception of the physical QoL domain, and correlations between some domains of QoL and motivation were observed.

Authors: Silva Aline Roberta Rodrigues da , Brito Patricia Dias de
Published: June 2021

Objective: To conduct an integrative review of serum levels of antioxidants and the effects of their supplementation on people living with HIV (PLHIV). Methods: A research was performed in the electronic databases LILACS and MEDLINE, using the descriptors "HIV" AND "antioxidants"; 110 publications were identified, 92 of which were available in the MEDLINE database and 3 in the LILACS database. After applying the exclusion criteria, 8 articles were selected for final evaluation.Results: The studies selected for the review were divided into 4 prospective observational studies and 4 clinical trials with supplementation of antioxidants or food sources of antioxidants. We observed that the initiation of antiretroviral therapy and its prolonged use negatively influenced the parameters of oxidative stress, and that deficiency of antioxidants was associated with more significant damage to mitochondrial DNA. Supplementation of foods that are sources of antioxidants, such as dark chocolate and spirulina, has had beneficial effects on serum lipids and antioxidant capacity. Conclusion: Clinical trials with a more robust methodology, supplementation of isolated nutrients, for more extended periods of intervention, and with the assessment of food consumption are necessary to elucidate their effects on oxidative stress in PLHIV faced with factors such as the use of antiretroviral therapy and changes in metabolic rates of this population.

Objective: To evaluate the support offered by health professionals to mothers of newborns admitted to the neonatal unit.Methods: Descriptive cross-sectional study with a quantitative approach conducted at the Regional Hospital of Tucuruí, in the state of Pará, region of the Brazilian Amazon, where 33 mothers who had newborn children admitted to the neonatal unit responded to the structured adapted version of the NPST (Nurse Parent Support Tool ). Results: Most were aged 20-34 years (48%), married or in a stable relationship (69%), multiracial (87%), housewife (57%), with up to 11 years of study (72%). The scores for the NPST subdomains were 3.39 ± 1.65 (Communication and Information Support), 4.13 ± 1.33 (Emotional Support), 3.93 ± 1.46 (Incentive Support), and 4.21 ± 1,27 (Instrumental Support). The findings revealed unsatisfactory communication and information support from health professionals to mothers, although they expressed satisfaction with the care provided. Conclusions: The perception of scarcity of human resources and health education, verified in this study, weakens the communication process during hospitalization and influences the mother's well-being, leading to a decrease in the efficiency of the support provided. The improvement in this area can lead to better results in daily practice. The replication of this study to other locations can lead to more significant assistance to mothers of hospitalized neonates and provide new technologies and strategies in health education.
Cold urticaria and your risk of anaphylaxis
Authors: Belluco Paulo Eduardo Silva , Sifuentes Bárbara Garcia , Ferreira Maurício Domingues
Published: June 2021

Cold urticaria (CU) is characterized by the appearance of wheals or angioedema after exposure to cold. It presents with mild to severe symptoms and can even lead to anaphylaxis. The risk of systemic reactions is high. We discuss this important pathology and show its strong relationship with anaphylaxis. Cold weather is one of the most common triggers for the onset of symptoms, with variables including humidity and thermal sensation. It is divided into acquired or familial forms. The diagnosis is made in patients with a medical history suggestive of the disease and should be confirmed with a stimulation test. The central aspect of treatment is to avoid cold stimuli. The prescription of self-injectable epinephrine for groups that are at high risk of systemic reactions is ideal. In conclusion, health professionals should be aware of CU in order to recognize the risk of anaphylaxis in these patients.

Authors: Vieira Gilberto Ramos , Leôncio Lívia Maria de Lima , Bezerra Clécia Gabriela , David Mírian Celly Medeiros Miranda , Matos Rhowena Jane Barbosa de
Published: June 2021

Objective: Hydration can favor cognitive functions during childhood and adolescence, helping with daily and school activities. This study aimed to identify possible interactions between hydration and memory in children and adolescents. Methods: This is a systematic review with meta-analysis. The bibliographic search was conducted in the MEDLINE/PubMed, SciELO, LILACS, Web of Science, Embase, and Cochrane Library databases, through a combination of the descriptors: “hydration” AND “memory”; “hydration” AND “memory” AND “child”; “hydration” AND “memory” AND “children”; “organism hydration status” AND “memory”; “organism hydration status” AND “memory” AND “child”. Results: The search resulted in 816 articles, of which ten were selected for qualitative synthesis and two for the meta-analysis. The results indicated that hydration could not enhance working, visual and visuomotor memories, or visual attention (Line Tracing Task, MD 0.67, 95% CI -0.87 to 2.22; Indirect Image Difference, MD 0.32, 95% CI -0.75 to 1.40; Letter Cancellation, MD 1.68, 95% CI -0.81 to 4.17). Conclusion: From the obtained results, hydration per se does not reinforce working, visual and visuomotor memories, or visual attention. However, there are still gaps regarding other types of memory and cognitive, motor, nutritional and environmental integration.

Introduction: Moderate and vigorous physical activity is essential to maintain proper body composition, to reduce the risk of ischemic heart disease, diabetes, and cancer. In addition, it reduces the risk of stroke, hypertension, and depression. Even so, it is an essential determinant of energy expenditure and, therefore, fundamental for energy balance and weight control. Objective: The objective of this epidemiological study is twofold: to quantify and qualify the physical activity of students at the Federal University of Mato Grosso (UFMT) and to compare the level of physical activity of incoming and graduating students. Methodology: The present study used the National College Health Behavior Survey (NCHRBS) questionnaire adapted and validated for use by Brazilian undergraduate students and addressed only aspects related to physical activity. Of the 18,986 students enrolled on UFMT's 5 campuses, 9,720 students accessed the questionnaire. Of these, 7,379 had their answers validated, corresponding to 75.92% of accesses or 38.87% of the universe studied. Results: This study found differences in the level of physical activity among university students, observing less physical activity on the Rondonópolis campus, less physical activity for students in the areas of Linguistics and Letters, when compared with students from other areas, less physical activity in students females when compared to males and less physical activity among freshmen compared to graduates. Conclusion: The study suggest the need for greater investment in policies to promote physical activity among university students in all areas.

We report on the results of experimental studies of the photoelectric properties of a GaAs p-i-n photodiode with InAs/GaAs(001) double asymmetric quantum dots (DAQDs) grown by self-assembling in Metal Organic Vapor Phase Epitaxy (MOVPE) process.
Three peaks were observed in the dependence of the photocurrent on the reverse bias measured at monochromatic photoexcitation of the DAQDs at the wavelength corresponding to the energy of interband optical transitions between the ground hole and electron states in the bigger QDs. These peaks were related to the tunneling of the photoexcited electrons between the QDs including the dissipative one (with emission and absorption of the optical phonons). The experimental results agree qualitatively with the theoretical field dependence of the 1D dissipative tunneling probability between the QDs.

The features of thin-film membranes, which are formed above round holes in silicon substrates using the Bosch-process are considered. The membrane has a complex shape due to the presence of the stress state of the initial films. The analysis of the dependence of the membrane deflection w on the supplied overpressure P is used to calculate the mechanical characteristics of the membranes. In this case, it is necessary to determine directly on the membrane its diameter, the thickness of the constituent layers, the change in the relief of the membrane surface over its entire area as the excess pressure P. Determination of the membrane diameter and the thicknesses of the constituent layers is shown by the example of p-Si*/SiNx/SiO2 and SiNх/SiО2/SiNх/SiО2 membranes. We used spectral ellipsometry, energy-dispersive X-ray spectroscopy, optical profilometry, optical microscopy. The influence of the peculiarities of the fixing conditions on the stress-strain state of membranes is shown, and the assessment is carried out by means of numerical modeling. A technique has been developed for measuring and calculating the mechanical characteristics of membranes that have an initial deflection. The calculation result is shown on the example of a membrane with an initial deflection of 2 µm – SiNх/SiО2/SiNх/SiО2 and a membrane with an initial deflection of 30 µm – Al/SiO2/Al.

Экспериментально изучен эффект резистивного переключения отдельных ферромагнитных филаментов мемристорных структур на основе функциональных слоев ZrO2(Y)/Ni. В качестве верхнего прижимного электрода виртуальной мемристорной структуры выступал проводящий зонд атомно-силового микроскопа. Обнаруженные особенности резистивного переключения биполярного типа связаны c разрушением и восстановлением филаментов, содержащих атомы Ni, в диэлектрической пленке ZrO2(Y) и предположительно обусловлены разной степенью металлизации филамента. Сформированные филаменты проявляются на изображениях, полученных с помощью магнитно-силовой микроскопии, как однодоменные ферромагнитные частицы. Ключевые слова: мемристор, резистивное переключение, атомно-силовая микроскопия, ферромагнитные филаменты.

The galvanostatic anodizing results of specially prepared high-purity aluminum in aqueous solutions of complex compounds K3[Co(C2O4)3] and K2[Zn(edta)] of various concentrations in the current density ranges 1.5–1.10·102 and 1.5−30 mA·сm−2, respectively. The kinetic features of anodizing have been established, indicating the occurrence of an oscillatory electrochemical process. Morphological features of a flaky and loose nature for K2[Zn(edta)] and monolithic for K3[Co(C2O4)3], uncharacteristic for anodic aluminum oxide, were revealed. The elemental composition, IR spectroscopic and photoluminescent characteristics of the formed oxides are shown.

The morphological characteristics of the surface of a number of films of elastomers based on polyurethanimides (PUI) were studied by atomic force microscopy (AFM). Significant differences in the surface morphology of PUI films were found depending on the composition: from granular morphology with different grain sizes or spongy morphology with nano - and submicron pores and cavities on the surface, to spherulitic morphology. It is shown that the roughness of the free surfaces formed during the films formation from the solution is significantly lower than the roughness of the surface which was in contact with the substrate. The influence of the chemical structure and size of the rigid diamine fragments in PUI macromolecules on the morphology of the film surface and the presence of different phases in the AFM torsion mode is established. The comparison of the deformation and strength characteristics showed high values of the elongation at break (more than 1400 %) in the PUI films with a developed porous structure of both surfaces. The results obtained show the need to control and take into account the morphological parameters of the surface layers of products made of highly elastic imide-containing materials for their use for technical and other purposes.

The characteristics of EMF (U) generation in the thin-film Pt/YIG structures caused by hybridization of propagating magnetostatic surface waves with exchange modes of YIG film were studied. It was shown that at frequencies f* corresponding to the dipole-exchange resonances (DER) the magnitude of EMF U increases by several times in comparison with the frequencies different from DER (f≠f*). The Volt-Watt sensitivity was estimated for the Pt/YIG structures with different geometries of Pt microstrips.

The results of experimental studies of the influence of the growth temperature and the thickness of the catalytic layer on the geometric and structural parameters of carbon nanotubes (CNTs) are presented. It is shown that the use of a TiN-based sublayer makes it possible to provide a low resistivity during the direct growth of CNTs on a conducting contact. It was found that for the formation of the best piezoelectric response, it is necessary to form the most defective CNTs. It is shown that the degree of defectiveness of CNTs can be controlled during their growth. A relationship has been established between the geometric and structural parameters of CNTs that affect the piezoelectric response. The potential applicability of CNTs for the creation of nanopiezotronic devices (nanogenerators, energy nanocarvesters) on their basis is shown.
