Nematerialusis kultūros paveldas: nacionalinių registrų kūrimas ir kultūros politika. Bulgariškoji perspektyva
Authors: Santova Mila
Published: December 2024

Bulgarian National Inventory of Intangible Cultural Heritage (ICH) was established
in 2001–2002. It covers basic areas of ICH according to UNESCO’s Convention for
the Safeguarding of Intangible Cultural Heritage (Convention 2003), consistent with
specificity of Bulgarian ICH in which context the main accent of formulation has been
changed a little bit. Inventory is based on composite parts of ICH. It consists of elements organized on two levels: national and regional. National level is a general version of ICH elements presented on Bulgarian territory. Regional lists are more precise
and they present specifics of ICH in different country regions. The elements included
in Bulgarian National Inventory of ICH are organized in typological leveled „orders”.
The constitution of an Inventory poses the question of its correlation with ICH archives. The information comprised into Archives is richer and highly varied than the
information included into Inventories, which would present it in the form of synthesis
on typological level. Of course this is directly related to their different functions. If as general an Inventory is and remains a state’s tool for direct operative actions than
Archive, so to say, bares the functions of “culture memories” depot. In this depot of
concrete culture memories the elements are fixed by pfoto-, phono-, video and other
types of documentation and becoming documents they will be treasured without any
changes. The type of formulation of elements which is invented in Bulgarian National
Inventory is open for continually repetition of an element which the State decided
necessary to safeguard by inclusion in the list.
An Inventory per se does not represent culture practices. The titles of elements included in it rather signify them as parts of the whole – ICH of particular state. By this
point of view an Inventory is a frame – it shapes the mental picture of ICH (of a community, a region, a state). The knowledge represented by ICH is a framing knowledge.
It just appoints but does not take part in developing the element. On its part the happening has been related to governmental culture policies. The scheme of large dimensions in Bulgaria is the National System “Living Human Treasures – Bulgaria”.
Vandos Zaborskaitės intelektualinės biografijos bandymas: formuojant literatūrologinius pagrindus
Authors: Jurgutienė Aušra
Published: December 2024

One of the most influential approaches to literary methodologies worked out by
Zaborskaitė in the Soviet period made solid foundations for our contemporary fiction
understanding. The aim of the article is to consider and assess the part of works dedicated to literary methodology by Vanda Zaborskaitė. That part consists of three books –
The Art of Poem, Introduction to Literary Science and preparation of the anthology
Poetics and Literary Aesthetics. Opposing to the official vulgar sociologization of lite
rature she followed the humanistic hermeneutical literary tradition taken from Vincas Mykolaitis-Putinas which stresses the psychological significance of art impact
(Erlebnis) in human life and continues the pan-aesthetical art conception created by
idealistic aesthetics. The inherited tradition of genetic, historical and aesthetic research of fiction was enriched by interpretation art, phenomenology and formalism
approaches. Zaborskaitė maintained rather pluralistic but in a way clearly defined attitude to literature allowing to combine historicity with logics, genetic criticism with
interpretational immanent. Her reading goal was to perceive the individuality of a
literary work which is not only motivated by description of its artistic structure integrity but limited and concretized by investigations of its author‘s outlook. By introducing and rationalizing the practice of interpretation of a separate literary work she, in
the same way as Staiger, pursued aesthetic and rhetoric suggestions of criticism.
Emilija Pliaterytė: "Titulinis puslapis” Margaret Fuller knygai Moteris XIX amžiuje
Authors: Chura Patrick
Published: December 2024

Margaret Fuller’s reading of Joseph Straszewicz’s The Life of Countess Emily Plater in
1844 apparently made a profound impression on the American feminist-transcendentalist. In Woman in the Nineteenth Century, Fuller included several admiring passages about Emily Plater and suggested an portrait of the Vilnius-born countess for
the work’s frontispiece. Selecting Plater as the emblem of her book showed that Fuller
had considered the meaning of Plater’s life and wanted readers of Woman in the Nineteenth Century, do the same. Fuller’s strong response to the countess was grounded
not only on the gender barrier transgression Plater embodied as a female military
figure, but on a number of biographical details that the two brilliant and forward
thinking women had in common. Looking at Woman in the Nineteenth Century and
The Life of Countess Emily Plater side-by-side suggests that Straszewicz’s biography of
Plater was a considerable influence on Fuller’s pioneering masterwork and, therefore,
on the development of American feminist thought in its earliest stages.
Nacionalumo tyrimai, tarpkultūrinė komunikacija ir kultūros mokslai

Education of communion, patriotism, self-awareness and choices is closely related to
the studies of nationalism, as the perception of identity and traditions of identification, development opportunities and future priorities, cross-cultural communication,
based on dissemination of tolerance and respect, and cultural studies, that form the
criteria of creativity, imagination and the joy of discovery. Cultural horizons, mediated
by evidencies as a prerogative of evidentiality, which do not need proof of the vast,
singularity and originality, promote the search of strong and meaningful support,
framework of assessment and behavior so that the cultural values would not be simulated or deliberately leveled down in order to lower value-bar as low as possible. The
priorities of intercultural communication – universality, diversity, traditionalism –
should strengthen more meaningful valuable landmarks and shape the values of culture, as a collective phenomenon, in the national consciousness.

Kultūros psichologija: įsivaizduojamos bendruomenės pokomunistinėje Lietuvoje
Authors: Juknevičius Stanislovas
Published: December 2024

The article analyses the opportunities of creating psychology of culture as a scientific
discipline. It looks at the psychology of culture relationship with cultural and intercultural psychology, considers theoretical and practical ways of expansion of traditional
culture research methods. The article is mostly based on Carl Gustav Jung ideas, in
particular, his teaching on the role of imagination in creation of the world, or in a narrower sense, of the cultural process. The theoretical assumptions of the research are
formulated in the first part of the study, according to which the analysis of some postcommunist Lithuania culture traits in the second part of the study is performed.
The article states that the human imagination is a major mental capacity which develops and supports the world. The creative process in such a case is seen as a birth
and spread of certain imaginative contents, the goal of which is to make individual
contents into collective imagination. The group of people who not only use the same
language, but also create the same or similar imaginative contents, can be called the
imagining community. Culture is the process by which the imagining communities
create the imaginary worlds. The analysis of these constantly emerging, changing and
evolving imagining communities and the imaginary worlds they create is the main
task for psychology of culture at this field of research.
The article examines imagining communities that are common to all the Western
world, as well as Lithuanian-specific ones. Attributable to the first type are the Catholics’, supporters’ of real politics, hedonists’ , dharma bums’, computer game players’, while to the second type – Lithuanian folk art stalwarts’, resistance fighters’,
rūpintojėlių (careful ones) imagining communities. The article states that some members of the latter two communities are experiencing a strong influence of collective
complexes. On the one hand, it is the complex of the Lithuanianess, on the second – the
one of Father Goriot. What is more, homo sovieticus mental traits remaining from the
Soviet times play a certain role in the life of Lithuanians as well.
Šiuolaikinės bendruomenės sampratos transformacijos
Authors: Savicka Aida
Published: December 2024

Probably no one questions nowadays that virtual space can become an alternative
“place” in the modern world where various forms of communal activities rise and are
supported. But there remain doubts as to whether this “networked” communality can
be grasped and considered by analogy with the communal spirit in the traditional
sense, which bases itself on direct interpersonal relationships and is territorially defined, with community members sharing a common cultural heritage.
There are those who argue that digitized local social networks can properly serve for
the sake of maintaining already existing community identities: by enriching direct
contacts of community members with virtual communication experience, the community feels more focused and in solidarity. On the other side, there are those who believe that ephemeral virtual communication environment poses significant obstacles
to build and maintain the spirit of confidence and mutual trust among people, which
is the basis for the formation of any community. It is exactly the lack of trust which
is recognized as the major reason for the decreasing spirit of traditional community. Special attention is drawn to the fact that the increasing numbers of narcissistic personalities use social networks to maintain their ego fed, to expose their lives and
not to sustain the communal spirit of cooperation, and these people are those who
fashion the culture of online communication.
So how the social networks that are setting up in cyberspace should be treated: a new
form of communal life, more responsive for the challenges of modern world, or rather
a networked publics, certain platform for masspersonal communication? One cannot
deny the fact that social networking platforms are used by many people for sharing
relevant information with those living in the neighborhood or for maintaining close
relationships with family members and friends, which means that there are some apparent expressions of communal spirit in these networks. However, it is necessary to
take into account the research data that show it is not the Internet that encourages
people to organize themselves into communities but the contrary: people actively
involved in the life of traditional communities and happy about it are more inclined to
use the Internet for communication with other members of the communities. In order
for a virtual community to last, consistent involvement of community members is required certain interest and motivation that spring of values and aspirations of people
gathering in the virtual space. Without them, these gatherings will be short-lived, and
communication – superficial. It is therefore important that neither Internet users nor
social observers overestimate the potential of community in cyberspace.
Erosas graikų kultūroje ir Platono filosofijoje
Authors: Kardelis Naglis
Published: December 2024

The author of the article presents a philosophical analysis of the understanding of
Eros in classical Greek culture and Plato’s philosophy.
First of all, in the preface presenting some preliminary remarks, the ambivalence of
Eros and the erotic, as generally understood by ourselves and the ancient Greeks, is
emphasized.
Then, in the first chapter of the main part of the article, the author focuses on the
specific erotic phenomena and their reflection in classical Greek culture, discussing
at some length various examples drawn from archaic and classical Greek literature,
Presocratic philosophy, and visual arts (especially sculpture). The ambivalence of
Eros, as reflected by the Greeks themselves in concrete and specific ways, is emphasized and reinterpreted by the author of the article. The ambivalence of the phenomenon of nudity in Greek culture is treated as a special relevant example in relation to
the quite different understandings of nudity, as well as its erotic connotations, in the
contexts of “high“ and “low“ art.
In the second chapter of the main part of the article, the author presents an analysis
of various conceptual manifestations of Eros in Plato’s philosophy, drawing attention to such Platonic dialogues as the Symposium, the Phaedrus, the Timaeus, the Republic, and the Laws. Special attention is given to the „erotic“ vitality of literary and
conceptual construal of Platonic texts. After that, the author presents both positive
and negative evaluations of the nature of Eros given by Plato in various dialogues.
Two Platonic texts – the Symposium and the Phaedrus – are analyzed more thoroughly
by way of discussion of those novel philosophical conceptions of the nature of Eros
which are presented in these dialogues and might be viewed as especially characteristic of Plato’s thought. The sublimation and „desexualization“ of Eros by conceptual
means which we find in Plato’s texts are shown to have a special philosophical function employed by Plato.
The relevance of Plato’s understanding of Eros to Plato’s philosophy as a whole is analyzed in the context of the philosopher’s effort to bridge the gap between the physical
and the spiritual, the material and the ideal, the concrete and the abstract. The conclusion is made that the original philosophical treatment of Eros in Plato’s philosophy
should be viewed as an instance of the common trend, very characteristic of classical
Greek culture, to view the erotic aspect of human life in novel, creative, and conceptually productive ways.
Dainų šventė kaip kultūrinės atminties veikmė
Authors: Žukauskienė Odeta
Published: December 2024

This article considers the tradition of Lithuanian Song and Dance Celebration as a
multifaceted phenomenon through the prism of contemporary cultural discourse.
Following the French philosopher Michel de Certeau the author examines Lithuanian Song Celebration as a modern cultural phenomenon, which shapes collective
representations of the past and imports traditional cultural heritage into cities. Song
Celebration is also defined as a site of memory (lieux de mémoire) significance of
which is outlined by the French historian Pierre Nora, and which is used to strengthen
national authority and promote patriotism. It is also examined as a practice of cultural memory (kulturelles Gedächtnis), which helps to reconstruct cultural identity and
foster self-reflexive processes, as the German researchers Jan and Aleida Assmann
claim. However, it is observed that in recent decades global memory projects integrate similar memory practices around the world in transnational networks. Besides,
the context of a very intense visual culture, multitude of festivals and spectacles requiring revision and actualizing of the song celebration concept, which should let to
speak openly and boldly about the interpretation of traditional culture and folklore,
its contemporary expressions, without turning it into the object of consumption and
finding original ways to open up the deep contents of ethnic culture.
Estijos Dainų šventė semiotiniu požiūriu
Authors: Veidemann Rein
Published: December 2024

The article focuses on the semiotic analysis of the Estonian Song Celebration within
the framework of the Tartu-Moscow school of cultural semiotics (the works of Juri
Lotman). It seeks to understand the historical context of the song festivals. The following segments are identified: the formation of the initial meaning under the influence of various impact sources; the repertoire as a text; the song festival as a ritual;
a dichotomy between exterior and interior form of the song festivals.
It may be stated that the Estonian Song Festivals reflects the centre-periphery relations. The tradition of choir singing of Southern Germany (Liedertafel) spread to the
Baltic provinces in the 19th century. Under the lead of Johann Voldemar Jannsen the
model of Baltic-German song festivals has been transferred to the first Estonian General Song Festival in 1869. The relations between cultural periphery and centre were
also a very important factor in the Brethren movement, which reached the Estonian
territory in the second half of the 18th century, and whose ideological pattern made
an impact on the Estonian national movement (national awakening) and the song
festival (the singing congregation). The questions concerning the authenticity of the
celebration (song festival as a text) and the Estonian culture (Estonian text) existed
in the air from the beginning. In one way or another it remained an important issue
and later. On one hand, this cultural transitivity gives exclusive meaning to the General Song Festival, representing Estonian culture – so called border-consciousness
culture – born on the border of Western and Eastern civilisations. On the other hand,
the General Song Festival functions as a text, and, metaphorically speaking, Estonians
believe so far in the holiness of song festival.
Lietuvybė ir Kitas kultūroje ir kultūrinėje atmintyje
Authors: Rubavičius Vytautas
Published: December 2024

Recently, we see the rapidly increasing number of scientific publications discussing the
nationhood, national and ethnic identity, as well as issues of nationalism, the connections of these phenomena with the ongoing integration policy of European Union and
the underlying governmental model having no ties with the statehood and identity.
It is therefore not only useful, but also very important to discuss Lithuanian national
identity development in modern times, the nation’s transformation to a modern nation
seeking statehood and restoring its sovereignty, the strengthening and dissemination
of Lithuanianness under the conditions of state-building policy, the modern nation’s
relations with the other ethno-cultural communities, prevailing images of those others
and stories about them, as well as more general peculiarities of Lithuanian nationalism in the broader context of the issues and problems of nationalism. It is important
to take into account the prevailing theoretical approaches, as well as deconstructive
trend to hold these phenomena as “imaginary”, and thus subordinate to manipulative
social engineering, denying their social reality. Author of the article stresses and discusses the primal expediency of the culture and cultural memory – to maintain and
strengthen local communal identity, paying attention to the fact that cultural memory
and identity always evolves in a certain area called the native land. The importance of
the Other for identity maintenance on the ground of we–others divide is highlighted.
The author pays attention to the main structure of the Other in the established modern
Lithuanian state, tackles the essential features of Lithuanian nationalism stressing the
importance of patriotic feeling, and considers Šalkauskis’ conception of patriotism as
wise love of nation’s individuality, which strongly influenced Lithuanian culture.
Kinas ir daugialypis atminties diskursas
Authors: Žukauskienė Odeta
Published: December 2024

This article discusses the ambivalent discourses of cinematography and memory. It
aims to show that a deeper exploration of memory is related to the development of
cinema, which actualizes memory-as-image. Visualizing realities that are exposed to
individuals as the remembering, cinema has become a part of memory technologies,
which gives meaning to the emotional memory and at the same time plunges memory
into the ocean of controversial visual culture, meaninglessness and oblivion.
As the form of prosthetic memory and the extension of human consciousness, cine
ma began to reflect on the memory and encouraged the development of memory discourse in the twentieth century. It contributed to the merging of collective memory
into individual memories, to the replacing “history” with “memory” and grand narrative with many small, local layers of remembrance, to the revival of oral history and
simple human experience. This opening of cinematic perspective, that weaves past
and present, established new forms and practices of cultural memory.
It can be observed that the profound impact of cinema on the collective imagination
and memory drew attention to the national cinematography as an important tool
to mobilize citizens, activate communities, reflect, reinforce and transform identity structures. Lithuanian cinematic culture survived the crisis at the intersection of
XX–XXI c. and also began to reflect on the processes of remembering and recall. The
disclosure of traumatic, repressed, false memory and its creative conversion into
long-term post-memory become one of the major tasks of cinema as a medium of cultural memory. Many different motifs of memory can be seen in documentaries as well
as feature films.
Bernard’o Stieglerio šiuolaikinės audiovizualinės atminties kritika
Authors: Vidauskytė Lina
Published: December 2024

An article focus on a critique of contemporary audiovisual technologies which was
made by famous French philosopher Bernard Stiegler.
For Stiegler, technics is an “organized inorganic matter.” He explores a history of technics as epiphylogenesis – the preservation in technical objects of epigenetic experience. Epiphylogenesis for Stiegler marks a break with genetic evolution which cannot
preserve the lessons of experience, a break which also constitutes the “invention” of the human. Stiegler in his later works analyses the impact of contemporary technologies and hyper-industrial capitalism to consciousness.
Human memory through contemporary technics expands and from mnemotechnics
becomes mnemotechnologie. Today mnemotechnologie maintains objective, impersonal memory while simultaneously and our knowledge. Various contemporary technologies take a large part of our consciousness and thus we lost our knowledge.
According to Stiegler, contemporary audiovisual technologies have a very deep impact
on individual consciousness. This impact depends on nature of individual consciousness and technics: both are temporal. Stiegler revises Kant’s, Bergson’s, Deleuz’s concepts of time. Introducing new “tertiary retention” concept Stiegler solves individual
and collective consciousness relationship. Audiovisual technologies create collective
consciousness: television enables a mass public simultaneously to watch the same
temporal object from any location. Such consciousness has nothing common with
individual consciousness. Stiegler’s analysis of cinematic time prolongs culture critique of Frankfurt School (Kulturindustrie). Stiegler renews this theme. Contemporary
audiovisual technologies stimulate pauperization of society. Similar to Stiegler about
contemporary technics writes another French philosopher Gilbert Simondon. An
alienation or pauperization is a main consequence of contemporary media.
Šiuolaikinio meno bienalizacija: interpretacija, kritika, recepcija
Authors: Žukauskienė Odeta
Published: December 2024

Considering the development of the global network of biennials, the article explores the trends and challenges of the biennialization of contemporary art The aim of the article is to reveal that biennial boom is associated with globalization and the dissemination of cultural industry. The functioning of the series of international exhibitions expands its sphere of authority, making art dependent on innovations, actualities and curiosities. Representing the field of cultural industries biennials generate the added value for culture and economy. In this process, the artistic dimension is overshadowed by the patterns of global economy and marketing, various ideologies, curatorial cult, competitiveness and innovativeness. One of the negative effects of biennialization is the decline of the professional art criticism. Through the integration of the theory and (un) critical mind, each biennial is engaging itself in the analytical reflection of the latest art processes. However, intellectual manipulations, publicity and promotion strategies obscure the essence of art, the sense of cultural phenomena and critical reflection. The article discusses the example of the Kaunas Biennial, which exposes that in the process of the biennialization the products of arts and cultural services increasingly lose their specific features. Creative, artistic and critical potential falls into the grip of soft totalitarianism.
Kinų bendruomenės ir kvartalai Vakaruose: kultūrų sąveika, koegzistavimas ar konfrontacija?
Authors: Poškaitė Loreta
Published: December 2024

Chinatown could be considered a universal and contradictory symbol of the Western imagination about the presence of the "other", or foreign culture and community in the midst of Western cities and communities. This imagination, innitialy formed in Nothern America after arrival of the first wave of Chinese immigrants and establishment of the first and the most famous Chinatowns, for a long time has been a part and parcel of the Orientalist discourse. It have influenced some theories of biculturalism and the interraction of the culture of origin and the one of dominant majority (or assimilative culture) as well. However, the processes of globalization and commercialization of cultures, the new waves and places of migration of Chinese to the Western countries have changed the landscape and the functions of Chinatowns. They were transformed from the marginalized "ghettos" or "ethnic enclaves" into the multicultural and transcultural spaces, thus challenging the Orientalistic treatment of Chinatown and view of Chinese immigrants as the "marginal humans".The article aims to elucidate the ideological reasons and theoretical basis in the treatment of the relations between Chinese (as immigrant, native) and Western (as host, dominant) culture, as it is reflected in the scholarly literature and popular media. The investigation aims to comprise few perspectives or interpretative discources, namely, the Orientalistic (or one of "Western domination"), sinocentric and transcultural (or global). In the first part, 1 will review the concept and stereotypical treatments of Chinatown, as well as their changes in the popular Western imagination, media and academical studies. In the second part I will discuss some anthropological investigations about the interraction of Chinese and Western cultures in the spheres of religion and Chinese/English language competences among Chinese immigrants, since those spheres are not only the most important for the maintenance and change of their cultural and ethnic identities, but also the revealing in particular the changing relations of Chinese and Western cultures.
(Šiuolaikinio) meno institucija kaip ideologinė medija
Authors: Šapoka Kęstutis
Published: December 2024

The article analyses (contemporary) art system and institutions as ideological media.
The author uses the concepts of repressive state apparatus and ideological state apparatuses formulated by philosopher Louis Althusser, according to which the essence of
military, religious, educational, as well as cultural institutions is the spread of ideological propaganda, ensuring ideological subjectivation. This means that each individual
adopts the ideology of dominant social class as its own model of thinking. Both totalitarian states and those that promote liberal capitalism use ideological interpellation.
It is precisely on this global ideological order that focuses the article, looking though
the specific prism at the (contemporary) art system. (Contemporary) art institutions
are interpreted as a ruphor of repressive neoliberal ideology and a kind of media, on
the one hand, spreading neoliberal consumerist propaganda. On the other hand, the
purpose of such institutions, in addition to the dissemination of ideological propaganda, is self-legtimation and the assurance of functioning of self-serving mechanics.
“Art” and “aesthetics”, as autonomous and ideologically independent fields, are suitable for both purposes.
Dailininkas modernistas tarybmečiu: laisvos kūrybos zona
Authors: Rubavičius Vytautas
Published: December 2024

The article discusses the peculiarities of remembering the Soviet era, highlighting
the importance of the Soviet way of life in understanding documents and works of
art. Trusting a variety of documents often overrides important document interpretation problems that are related to the “rules” of daily life not recorded in any written
sources, as well as the context of document preparation, harmonization and adoption, and the medium of social relations. Artists have been tempted to serve with their
creations to governing power and to live well, to express themselves in public life, to
gain public attention and signs of government respect, while at the same time being
very clearly aware of what repressions, camps or other social non-being forms are
awaiting disobedient. Therefore remembering the Soviet era, it is important not to
miss out on a particular aspect of experience, which should be defined as the creation
of “freedom zones”. The “freedom zone” of artists was the result of their creative selfdetermination, which could be supported by the institutional environment. The author analyses the artworks of Vincas Kisarauskas and Vincentas Gečas, representatives of Lithuanian modernism, painted in the first half of the seventies. The historical
story of postwar resistance to the Soviet occupation is raised in Kisarauskas’ paintings, and we perceive the paintings as a testimony and a creative commitment to
combat. Gečas’ paintings emphasize the separation from the canons of Soviet art, expressionistically depicting insignificant scenes from the everyday life, highlighting the
importance of the picture plane and composition, and refusing the completeness of
the painting’s background. Attention is drawn to the special institutional environment
of the “free creative zone” created and maintained by Gečas, as the superior member of the party nomenclature and as the prime vice-rector and later long-time rector
of the Art Institute, and which was further maintained by Kisarauskas, a long-time
teacher of painting at the M. K. Čiurlionis Secondary Art School in Vilnius.
grandeza sai de cena
Authors: Gomes Rodrigo Rafael
Published: December 2024

Este trabalho aborda um capítulo não publicado do livro As ideias fundamentais da matemática, do matemático, engenheiro e astrônomo brasileiro Manuel Amoroso Costa. O exame dos rascunhos de próprio punho do livro, contidos no arquivo pessoal do autor, revelou a existência de um capítulo que Amoroso Costa escreveu para o livro, mas que decidiu suprimir, que trata do conceito matemático de grandeza. O conteúdo desse capítulo é discutido neste artigo, que também apresenta transcrições de alguns fragmentos da segunda versão do texto inédito. A análise do capítulo revela forte influência do lógico-matemático Louis Couturat, cujas ideias são aqui expostas, além de sugerir que o processo de abandono do paradigma da matemática como ciência da grandeza, na passagem do século XIX para o XX, pode ter repercutido no processo de elaboração do livro.

Bioresonance Therapy as an Innovative Method of Bioquantum Medicine
Authors: Titarenko Iurii
Published: December 2024

Bioresonance therapy is a cutting-edge approach that uses electromagnetic waves to restore the body’s natural bioelectric balance and activate inherent self-healing mechanisms. It is steadily gaining recognition across diverse medical fields – ranging from allergology and neurology to metabolic disorders and oncology. This article examines the clinical outcomes associated with employing bioresonance for the treatment and support of various patient groups, including those with allergies, autoimmune conditions (notably those related to Lyme disease), metabolic imbalances, chronic pain, depression, cancer, and other health challenges.
Of particular importance is the therapy’s demonstrated effectiveness in alleviating allergic reactions, stabilizing metabolic processes, managing neurological conditions, and mitigating the adverse effects of conventional cancer treatments. Beyond these benefits, bioresonance not only enhances patients’ overall well-being, but also complements traditional therapies by improving their outcomes, minimizing side effects, and hastening recovery. It has shown promise as a means to refine and optimize existing treatment regimens, thereby paving the way for more comprehensive patient care.
The article also highlights the method’s potential applications in routine medical practice and emphasizes the necessity of further clinical trials to identify optimal therapeutic parameters and clarify its mechanisms of action. Bioresonance therapy could become a crucial adjunct to traditional medical strategies, substantially improving patients’ quality of life. As ongoing research continues to elucidate its role, incorporating bioresonance into integrated treatment plans may broaden therapeutic horizons, enabling personalized, preventive, and more effective healthcare solutions for the future.
Insect Pollinator Voucher Collection: Pollinator Visitation to Pacific Northwest Native Plants and Native Cultivars

Published: December 2024

Planting native flora continues to grow in popularity as a means of conserving pollinator fauna in fragmented landscapes. Due to the limited availability of native plants, consumers may encounter cultivars in their search for plants native to their region. Though consumers have a documented interest in planting native flora for their purported benefits to pollinators, it is unclear whether cultivars provide the same benefits as wild-type native plants. Over three years (2020-2022), we observed and collected pollinators from a common garden experiment in Corvallis, OR containing 8 species of Pacific Northwest native plants, 18 cultivars derived from native plant species, and one exotic perennial plant. Methods for collection are described in further detail in Hayes et al. (in prep.). Here, we report on and document the deposition of taxonomic voucher specimens which represent the primary species concepts used throughout Hayes et al. (in prep.) (Accession #). Specimens were identified to the lowest possible taxonomic level by L. R. Best (bees, Hymenoptera: Apoidea) and J. J-M. Hayes (syrphid flies, Diptera: Syrphidae). The vouchered material includes 139 individual specimens with at least one representative per caste and sex, as available, of 55 species and 14 morphospecies of bees (Hymenoptera: Apoidea) and 13 species and one morphospecies of syrphid flies (Diptera: Syrphidae). Additional vouchers are included for specimens identified only to the morphospecies level, and Megachile brevis Say, 1837 individuals that were captured while collecting sections of petal from Clarkia amoena (Lehm.) A.Nelson & J.F.Macbr. plants. These 139 voucher specimens come from a much larger dataset, containing over 6,500 observational records of plant-pollinator interactions.

Plasma diagnostics is a crucial field for understanding and analyzing plasma properties, employing various techniques to determine the most important parameters such as electron temperature, density, and energy level distribution. Among these techniques, Optical Emission Spectroscopy (OES) is distinguished by its simplicity and cost-effectiveness. This study focuses on the OES line Ratio Method, which relies on measuring the ratio R, defined as the intensity ratio of two spectral lines that are directly linked to the electron temperature and energy distribution. The study identifies a critical constant C, which represents a critical value of the intensity ratio; its value indicates the degree of equilibrium. Furthermore, the method demonstrates its ability to identify population inversion, which is important in laser studies. Our study shows that the OES line ratio method is used to determine the electron temperature only in the case of R << C. The findings reveal that the temperature values obtained using this method align with those calculated through other approaches, such as the Boltzmann Plot Method, or those measured using Langmuir probes, confirming the method's reliability in diagnosing low-density, low-temperature plasma. We applied this method to the measurement of electron temperatures in the MDECR plasma, which were found in the range ( ) for argon. This result is comparable to those obtained by other methods, such as the Boltzmann diagram method ( ) or those obtained by other instruments, such as the Langmuir probe ( ).

This study investigates the effects of polypropylene fibres and cement on the properties of Chlef sandy soil, addressing the challenges posed by weak or unsuitable soils in geotechnical engineering. Fibre reinforcement and cement stabilization are explored as effective, cost-efficient solutions for improving soil strength in applications such as pavement layers and retaining walls. A series of laboratory tests, including compaction, unconfined compressive strength (UCS), and California Bearing Ratio (CBR), were conducted to analyze the effects of adding polypropylene fibres and cement on the soils engineering behavior. The fibre content was varied from 0 to 0.8% by weight, with 5% cement content, and the specimens were cured for 7 and 14 days. The results show that both cement and fibre additions increase the maximum dry unit weight of the soil. The UCS increases with higher fibre content, with a maximum improvement of 170% at 0.8% polypropylene fibre after 14 days of curing. Curing time also positively affects UCS, with more significant improvements observed at higher fibre contents. Furthermore, the combination of cement and polypropylene fibres significantly enhances CBR values. For instance, the unsoaked CBR value increased by 64% with the addition of 5% cement and 0.8% polypropylene fibres. These findings suggest that cement and polypropylene fibre reinforcement can notably improve the engineering properties of sandy soils.

Electric vehicles (EVs) have several advantages over fossil fuel vehicles, which reducing greenhouse gases and air pollutants. The selection of control systems play a pivotal role in the overall functionality, efficiency, safety, and user experience of electric vehicles. This study focuses on an EV with a two-wheel drive (TWD) configuration powered by a permanent magnet synchronous motor (PMSM) and a battery. The motors are controlled by a field-oriented control (FOC) method without a speed sensor, addressing common sensor issues. An electronic differential is included to maintain the balance of the EV during operation. This research mainly contributes to the integration of an extended Kalman filter (EKF) to solve the speed sensor issue in EVs based on FOC control. Additionally, the study addresses the challenge of determining the nine parameters of the FOC algorithm's controllers using the particle swarm optimizer (PSO) and grey wolf optimizer (GWO). The Kalman filter provided excellent stability for the EV, and the GWO achieved significant improvements: a 5% dicrease in speed error, a 10% dicrease in torque ripples, and a 9% improvement in current wave forme, compared to the PSO algorithm.

Published: December 2024

Excavating underground structures, like tunnels or galleries, disrupts the soil's stress and deformation state, potentially compromising excavation stability and inducing significant ground damage. Ground movements are common challenges during such constructions, often attributed to adverse geological, geotechnical, or hydrological conditions, including groundwater-induced swelling and seismic loads. This article aims to model a pathological case of the T1 tunnel of Djebel El Ouahch (East-West highway). It studies the pathological conditions by examining the stress and strain states both in the surrounding soil and in the tunnel wall. To do this, a numerical analysis was carried out using the FLAC2D calculation code, which uses the finite differences method (DEM) to study the stability of a section of the T1 tunnel, calculate the stress state, and evaluate soil displacements and their impact on the structure.

The aim of this research is to study the exploitation of local soils in earthen construction. This is why there is a return to traditional materials, while focusing on modernizing them. The concern to manufacture earth blocks with good mechanical properties, while enhancing local soils, was thus the subject of this study. The soil was chosen as the reference material. Chemical stabilizers were incorporated to increase the mechanical strength at a given static compaction pressure. In order to optimize the choice of materials used (soil, binder), a statistical process was used through the experimental design method to model the mechanical behaviour of the composite studied and thus deduce the optimum of the factors that lead to the desired improvements. The results obtained showed that the addition of a binder, which is lime, causes a decrease in dry densities with a slight increase in optimal water contents. In addition, there is also an increase in compressive strength with the increase in lime content. Finally, it should be noted that the experimental design technique used to model the mechanical behaviour of the composite studied provides encouraging and promising results. It may replace or supplement experimental tests. It is an effective and less expensive method that minimizes the number of experimental trials.

This study attempts to shed light on the analysis of the static behavior of simply supported FG type property gradient material beams. A new 2D refined beams theory is presented to model the displacement field. Young's modulus is considered to vary gradually and continuously according to a power-law distribution in terms of volume fractions of the constituent materials. The equilibrium equations are obtained by applying the principle of virtual work. Based on principle of virtual work, the equilibrium equations are drawn including the material parameters, and compressive forces. An analytical approach for simply-supported is implemented. The governing equilibrium equations are thus solved by using the analytical model developed here and Navier's solution technique for the case of a simply supported sandwich beam. Moreover, Using the numerical results of the non-dimensional stresses and displacements are calculated and compared with those obtained by other theories. Two studies are presented, comparative and parametric, the objective of which is the first to show the accuracy and efficiency of the theory used and the second to analyze the mechanical behavior of the different types of sandwich beams under the effect of different parameters. Namely the material index (k), the thickness ratio (a/h) and the beam type.
