Published: November 2022

A saját otthonukban élő idősek esésgyakoriságának, eséskockázati tényezőkkel kapcsolatos ismereteinek és az esésmegelőzéssel kapcsolatos mindennapi viselkedésének felmérése. 173 fő idős körében végeztük a vizsgálatot. A szociodemográfiai változók mellett vizsgáltuk az esés gyakoriságát, az esési kockázatot, a kockázati tényezők ismeretét, a lakóhely környezetének módosítását és a mindennapi esésmegelőző viselkedést. Leíró és matematikai statisztikai (χ2-, t-próba, korrelációszámítás) módszert alkalmaztunk (p<0,05). Az idősek 37%-a esett el az elmúlt egy évben és közülük 81,2% sérülést is szenvedett. A rizikótényezők közül a módosítható kockázati tényezőket fogadták el legkevésbé az idősek. A biztonságos környezet kialakításának gondolatával a minta 72,8%-a foglalkozott, de tényleges beavatkozást csak 52,9%-a végzett. A változtatások inkább nők körében voltak jellemzők (p=0,025). A prevenciós tevékenységek közül a legalacsonyabb számban a segítség kérését (12,1%), a járást segítő eszközök használatát (18,5%) fogadták el. Azon esésmegelőző programok szükségesek, amelyek a módosítható kockázati tényezőkre helyezik a hangsúlyt.

Published: November 2022

Magyarországon mintegy 3,5 millió ember panaszkodik rendszeresen fejfájásról. A kutatásunk célja a hallgatók körében felmérni a fejfájás előfordulását, okait és tüneteit. Kvantitatív, keresztmetszeti kutatást 2021.03.01.–2021.11.30. között végeztünk. Nem véletlenszerű, célirányos szakértői mintavétel célcsoportja az elmúlt három hónapban fejfájásra panaszkodó, 18–45 éves egyetemi hallgatók (n=111). Saját szerkesztésű és validált kérdőíveket alkalmaztunk (Athén insomniaskála és PSS). Leíró statisztikát, kétmintás t-próbát, korrelációt, ANOVA-t és χ2-próbát számoltunk SPSS 22.0 program segítségével (p<0,05). Az elsődleges fejfájások közül 63,06% tenzióst, 8,11% migrént, 4,5% clustert és 24,32% kevert típusút detektáltunk. A fájdalom intenzitása szignifikánsan összefüggésben volt a fejfájás megjelenésének gyakoriságával és időtartamával (p<0,05). A fájdalom intenzitása nem mutatott szignifikáns kapcsolatot a stressz-szinttel, az alvászavar kialakulásával, a fejfájás típusaival, a koncentrációképesség csökkenésével és a tanulási módszerekkel (p>0,05). Elmondható, hogy a fájdalom intenzitását a fejfájás megjelenésének gyakorisága és a fájdalom időtartama befolyásolja.

Fractal Behavior in Bulgarian Day-Ahead Prices Based on Detrended Fluctuation Analysis
Authors: Popovska Ekaterina , Gospodinov Mitko
Published: November 2022

This study investigates the hourly prices of the electricity day-ahead market nonstationary characteristics and long-range correlation. Using the detrended fluctuation analysis (DFA) approach, we show evidence of long memory for the Bulgarian day-ahead market between January 20th, 2016 and December 31, 2019. Furthermore, the results from the DFA methodology shows that behavior of the hourly electricity spot prices returns were long term positively correlated. DFA methods can be used as powerful tools for analyzing very volatile series like electricity prices considering the fact that in recent years prices become more volatile due to increased integration of renewables that are intermittent and far more volatile than other commodities normally considered with extreme volatility. Day ahead electricity prices are crucially important for forecasting, derivatives pricing and risk management and therefore in this paper we give a brief introduction on DFA method.

Analysis of Heart Rate Variability Using Photopletismnographic and Electrocardiographic Signals
Authors: Gospodinov Mitko , Gospodinova Evgeniya , Lebamovski Penio
Published: November 2022

Heart rate variability (HRV) is a non-invasive marker for monitoring the physiological condition of patients and assisting in the diagnosis of cardiovascular disease. The aim of this study was to investigate the consistency between HRV parameters based on photoplethysmographic (PPG) and electrocardiographic (ECG) signals. Parameters from the linear analysis in the time domain were studied. The time domain indices are standardized and widely used to calculate HRV. These indices are statistical and geometric measurements. The statistical calculations of the successive heart rate intervals (RR interval series) are strictly interrelated (SDNN, SDANN, RMSSD, pNN50), while geometric measurements are based on TINN and HRVTi parameters. The ECG and PPG signals of a healthy individual were examined. The obtained results show a very good agreement between the HRV parameters obtained from the two types of signals. In view of this finding, it can be concluded that the PPG offers an alternative ECG option for HRV analysis without compromising accuracy. The correspondence between the studied parameters applied to the two types of signals provides potential support for the idea of using PPG instead of ECG in the extraction and analysis of HRV in outpatient cardiac monitoring of healthy individuals and patients with cardiovascular disease. A study of two groups of individuals: healthy and with cardiovascular disease based on PPG signals by applying the method: analysis in the time domain. The obtained results show that with the used method the two studied groups of subjects can be distinguished.
Registering and Processing of a Photoplethysmography Signals
Authors: Cheshmedzhiev Krasimir
Published: November 2022

Heart rate variability (HRV) is a non-invasive indicator of the condition of the cardiovascular system. To calculate HRV, the time between two adjacent R peaks of the electrocardiogram of the individual is used, i.e. between two heartbeats. This method requires the placement of electrodes in certain places on the body of the individual. An alternative way to measure heart rate is to use the change in blood volume in the blood vessels, through optical method, so-called photoplethysmography. It is based on the measurement of the change in light absorption depending on the amount of blood in the blood vessels. This article discusses ways to capture photoplethysmographic signals and convert them into data suitable for further processing. Graphs of the data from experimental studies at different stages of their processing are presented.

Authors: Gospodinova Evgeniya , Lebamovski Penio
Published: November 2022

Automatic analysis of ECG signals makes it possible to assess the health status of patients, reducing the likelihood of human error and ensuring optimal and accurate results. The presentation of heart rate in the form of a dynamic series of RR intervals (intervals between successive heartbeats) and the application of graphical methods (Poincaré plot, Detrended Fluctuation Analysis and Multifractal Detrended Fuctuation Analysis) for analysis are an objective and non-invasive way to obtain information about the functional state of the organism. The present study presents the results of graphical analysis of RR interval series based on ECG signals of healthy and unhealthy subjects. The analysis is performed with the help of developed software for determining the nonlinear characteristics of the studied signals and the formation of graphical assessment of the health status of patients.

LATVIAN AMATEUR DOCUMENTARY FILM, 1970s–1980s: FAMILY, COMMUNITY, TRAVEL, AND POLITICS IN THE FILMS OF ULDIS LAPIŅŠ, INGVARS LEITIS, AND ZIGURDS VIDIŅŠ
Authors: Strupule Inese
Published: November 2022

In the 1950s, amateur filmmaking had become a well-established feature of everyday life in the Soviets Union. However, in contrast to the state film industry, no centralized governmental body existed to control amateur filmmakers. As a result, state ideology was not always the primary motivation for making amateur films. The works that dared to experiment invariably emerged from the periphery, and the Latvian SSR became one of the citadels of the Soviet amateur film movement. Drawing upon the amateur film collection held at the Latvian State Archive of Audiovisual Documents, this paper will identify and analyse the various functions that amateur documentary filmmaking performed beyond its ostensible mission of transmitting Soviet ideology, and examine its role in creating alternative political, social, and cultural meanings, and prospects for national identity development and heritage preservation. It will primarily focus on the documentaries by Uldis Lapiņš, Zigurds Vidiņš, and Ingvars Leitis made in the 1970 and the 1980s, and look at how they used everyday matters – such as family, community, and travel – to express artistically as well as to address broader social and political issues of life in the post-war Soviet society.
THE “CREATIVE TREATMENT OF ACTUALITY”: POETICS AND VERISIMILITUDE IN LAILA PAKALNIŅA’S FILMS
Authors: Bruveris Klara
Published: November 2022

Laila Pakalniņa is a contemporary Latvian filmmaker who works across both documentary and fiction film. Her films are often regarded as avant-garde, experi- menting with genre conventions, challenging her audiences to reconsider their understanding of narrative and the cinematic form. Her work also pushes the boundaries between what constitutes fiction film and what constitutes documen- tary. This arguably occurs because of her engagement with the tropes of poetic documentary cinema, of which there is a strong tradition in Latvia due to the famous Riga School of Poetic documentary established in the 1960s. This paper examines her documentary film Čau, Rasma (“Hi, Rasma”, 2014) as a continu- ation of the poetic documentary tropes developed by John Grierson, and argues that verisimilitude can be found in her documentaries through an application of Grierson’s philosophical work. The paper aims to contribute to a broader discus- sion of poetic documentary practices in the current era, and how this documentary approach has developed from its modernist beginnings.
ENVIRONMENT AND ECOLOGY ISSUES IN WORKS OF GERMAN STREET ART
Authors: Taškāne Alise
Published: November 2022

This article deals with the development of environmental and ecological issues in Germany since the 1970s, and how these issues are represented in works of street art since the beginning of the development of modern graffiti, and later street art, in Germany. The purpose of this research is to identify differences in the ecological and environmental issues in works of graffiti and street art from the 1970s to present day in Germany. This has been done by examining general themes of environmental and ecological issues in graffiti and street art and by studying some of the specific examples of artwork, using research methods by visual analysis based on study “Reading Images: The Grammar of Visual Design” by Gunther Kress and Theo van Leeuwen, and visual analysis of iconography and iconology, described by Marion G. Müller in “The SAGE Handbook of Visual Research Methods” by Eric Margolis and Luc Pauwels. The first phase of the research involves an overview of the socio- political background of the ecological and environmental issues in Germany since the 1970s, as well as development of modern graffiti and street art in Germany in the context of ecology and environment, using the method of iconology. The second phase involves examining physical examples of graffiti and street art in Germany. The final phase deals with regional differences reflected in artists’ work in Germany. This article will provide general insights in graffiti and street art in Germany and it will explore how German artists tackle the environmental and ecological issues in their works.
PRESERVATION OF STREET ART IN PARIS. AN EXAMPLE FOR RIGA?
Authors: Želve Valērija
Published: November 2022

In many cities graffiti and street art is considered as vandalism and is often connected with crime. However, in some cities majority of the population does not agree with such a statement. They see street art and graffiti as decoration of the city. They think the artists deserve a safe space for expressing themselves. It is already a little step towards preserving the street art movement, as, of course, not all the citizens will share this opinion, since place of street art is still a very arguable question in many cities around the world. More and more organisations, associations and projects of different types are being created to promote and protect the urban art. Promotion of street art can be expressed in different ways, for example, panel discussions and workshops, exhibitions and festivals. Several street art and graffiti related spaces are being opened in Paris. Museums, warehouses, walls, schools – every kind of space could be used as a platform for the artists. This is also a nice way to show to the city council how important this culture is to the citizens of Paris. At the same time Riga cannot be yet proud of a thriving street art and graffiti culture. But what if Riga actually took Paris as an example? Could similar organisations in Latvia improve the society’s attitude towards urban cultures? Could the safe platform for street art be a solution for its popularization in Riga? The aim of this paper is to introduce organisations which promote and protect street art and graffiti in Paris and to evaluate if street art positions in Paris could actually be an example for Riga. The conclusion is that the bigger amount of such organisations is able to actually change the attitude of society towards the urban art and Riga can surely learn a lot from Paris – creating spaces for graffiti and street artists can not only make their positions better, but also it can have a positive impact for the city’s social life and attract a specific type of tourists to the capital.
PROTECTION OF STREET ART (GRAFFITI) FROM THE PERSPECTIVE OF LATVIAN AUTHORS’ LAW
Authors: Mantrov Vadim
Published: November 2022

Street art (covering all street art types including graffiti) is considered as one of expressions of urban life and, simultaneously, one of peculiar intellectual creations. For years, street art was not recognised as a type of art and was usually subject to public condemnation, but street artists were (and still are) subject to liability arising from vandalism (hooliganism) acts. However, attitude against street art and its different expressions has been changing in recent years becoming recognised and valued as a specific type of modern art. This shift has been influenced by visual attractiveness of different creations of street art mainly murals containing graffiti; commencement of commercialisation of street art including sale of murals embodying graffiti at auctions; and court disputes over protection of street art expressions. Street art including graffiti may be subject to legal protection, yet it depends on a particular jurisdiction. The aim of the present article is to consider possibility of protection of street art in Latvia from the perspective of authors’ law (i.e. copyright) law. This paper discusses specific issues in relation to street art for its protection within Latvian authors’ law such as authorship as street artists usually create street art expressions anonymously; the concept of work by discussing compliance with criteria put forward to a work under authors’ law; integrity of a work as street art expressions such as graffiti are usually murals involving a clash between property law and authors’ law; distinction of street art from pure vandalism; and necessity for specific rules addressing specific nature of street art. The paper provides conclusions for identifying proper place of street art within legal framework of Latvian authors’ law.

Post went viral and soon the group reached 500+ members, all hunting street art in Riga and posting online their findings. It took about 2 months to create initial street art map covering most of the notable street art object of the city. Later new created artwork was added and identified destroyed art work is marked with black markers.
ANSIS EPNERS’ FILM “ALIVE”: FROM DOCUMENTARY TO FICTION
Authors: Balčus Zane
Published: November 2022

The first short documentary “Alive” (Dzīvs, 1970) is an important signifier of Latvian director Ansis Epners’ (1937–2003) oeuvre both in terms of his approach to documentary film practice, and growing interest in fiction filmmaking. The film “Alive” and later idea to develop a full-length fiction film based on its main character demonstrate Epners’ unconventional expression of both kinds of filmmaking, which was received with a mixed response at the time. Epners used performative elements in the documentary, and included real-life character playing himself in the planned fiction film, challenging the assumptions and conventions of filmmaking practices in Latvia at that time. In this article I will analyse Epners’ formal and stylistic choices in the film “Alive” and its reception in the early 1970s, and the script for the fiction film based on the main character of the film “Alive” Arnolds Cīrulis. The reception of “Alive” shows the contradictions between the dominant views on the documentary film form and Epners’ work. The fiction film script, which was not turned into film, remains as an example of versatility of Epners’ ideas on the potentials of fiction filmmaking.
DOCUMENTARY DISCOURSE: COGNITIVE AND PHENOMENOLOGICAL REFLECTIONS ON MATTERS OF REMEMBERING AND AUDIO-VISUAL MEMORY
Authors: Valkola Jarmo
Published: November 2022

The article examines the ramifications of documentary discourse. The approach is formulated to give a voice to interdisciplinary research on documentary. The em- phasis on the close analysis of extracts and larger documentary entities will bring a new level to this meeting of various aspirations. It gives the possibility to create a heightened sensitivity of matters of analysis that covers similarities and differences, as well as causal and empirical reflections. The aim is to create a web of associations for these perspectives and perceive a wider approach on documentary in order to ar- gue that the meaningful appropriation of various tendencies in documentary studies requires sufficient correspondence and dialogical proneness for an understanding of the conceptual, formal and aesthetic legitimacy of this phenomenon. The essential part of the investigative strategy relies on cognitive mapping, which means a combination of individual and collective perceptions. Furthermore, cognitive mapping enables the viewer to practise distinct perceptual, phenomeno- logical and cognitive activities. It also features a methodical device that is related to a contemplative attitude towards the discourse of documentary, forming a relationship between the projected images and sounds and a mind that observes them. This leads to a method of aesthetic contemplation that is connected to a disciplinary logic of inscription which aims to produce insights and patterns of thought provoked by filmic affectations. In this article, the focus lies especially on questions of remember- ing and audio-visual representation of memory issues. The article features three film examples, which are Patricio Guzmán’s “Nostalgia for the Light” (Nostalgia de la luz, Chile, 2010), Pirjo Honkasalo’s “The 3 Rooms of Melancholia” (Melancholian 3 huonetta, Finland, 2004), and Chris Marker’s “Sunless” (Sans soleil, France, 1983). These films are cinematic re-meditations of past and present, and forms of audio-visual ethnography. The resulting inferences and elementary conclusions include that they aspire to demythologize the past, and bring forth a mode of representation, which features an elevated and sensory form of documentary discourse, connected with artistic signs of narrative, performative and aesthetic connotations.
MICHAEL CHEKHOV, SPIRITUALITY AND SOVIET THEATRE
Authors: Byckling Liisa
Published: November 2022

The present article discusses the work of Michael Chekhov, director of the Second Moscow Art Theatre from 1922 to 1928. After the October revolution Chekhov sought to withstand the threat from those ideological tendencies which led away from the ideals and spiritual values of his teacher Konstantin Stanislavsky. The reasons for Chekhov’s emigration were connected both with his opposition to Soviet cultural policy and the repression of religious groups in Russia. Chekhov was the most famous follower in the Russian theatre of the anthroposophist, Rudolf Steiner. In his production of “Hamlet” Chekhov also followed the spiritual ideas of the Russian symbolists while applying new methods of acting.
LA MODALIDAD EPISTÉMICA EN ELE: RETOS EN LA DESCRIPCIÓN DE LA SEMÁNTICA DE VARIAS UNIDADES EN MATERIALES DIDÁCTICOS. EPISTEMIC MODALITY IN SFL: CHALLENGES IN THE DESCRIPTION OF THE SEMANTICS OF SOME UNITS IN A CORPUS OF DIDACTIC MATERIALS
Authors: Izquierdo-Alegría Dámaso
Published: November 2022

Spanish possesses a vast array of items that codify the speaker’s degree of certainty or doubt (i.e., epistemic modality), such as quizá, igual, seguramente or sin duda. Little attention has been devoted to them in the field of Spanish as a Foreign Language, especially regarding their semantics. The aim of this article is to show that some of the semantic descriptions of such items reveal inconsistencies in a variety of didactic sources, and this might hinder students from mastering them. We focus on three case studies involving (a) where certain items are allocated in the epistemic scale, (b) how a group of similar expressions is treated, and (c) how the semantics of an adverb is described vis-à-vis its cognates in other languages.
FACTORES DE ÉXITO DE UN PROYECTO DE TELECOLABORACIÓN EN EL CONTEXTO DE LA ENSEÑANZA Y APRENDIZAJE DE SEGUNDAS LENGUAS. SUCCESS FACTORS OF A TELECOLLABORATION PROJECT IN THE CONTEXT OF SECOND LANGUAGE TEACHING AND LEARNING

Published: November 2022

Telecollaboration projects between higher education institutions have been focusing mainly on the development of L2, intercultural and digital skills of the learner [Dooly & O’Dowd 2012]. In spite of the increasing number of studies investigating this type of projects, there is still little research on telecollaborative practices that connect L2 Spanish learners with student teachers with a double focus on (1) how reciprocity between learners with different learning goals is met, and (2) what success factors guarantee the sustainability of the exchange over time. This article presents the RUG-UB telecollaboration project that was implemented over 4 academic years (2013–2017) in the University of Groningen and the University of Barcelona, and which laid the foundations for another telecollaboration project that continues to be developed between the University of Barcelona and the University of Iceland at the time of writing this article. After describing the academic context and task design, the results of the experience are presented and analyzed. Finally, the factors that have contributed to the consolidation of this project are discussed, such as the design of tasks which address the reciprocity between learners with different learning objectives, or the ability of students, teachers or institutions to adapt to change.
VISUAL RESEARCH METHODS IN THE STUDY OF TRADITION: THE CASE OF THE LATVIAN SONG AND DANCE CELEBRATION
Authors: Laķe Anda , Vinogradova Līga
Published: November 2022

Most researchers, focusing on the study of tradition, admit that the term tradition has several meanings that are open to different interpretations. Sociology, anthropology, and ethnology apply different approaches to the study of tradition; yet it has been often researched also interdisciplinary, using various theoretical and empirical tools. The choice of the empirical methods was largely determined by the theoretical approaches to the concept of tradition, especially ethnologist Simon J. Bronner’s premise that all the explanations of tradition perceive it as a subjective phenomenon that does not easily yield to reflection and usually manifests itself as an intrinsic and intangible part of everyday life. The specific nature of tradition has encouraged the development of methods suitable to the analysis of symbolic practices which are difficult to read. The above considerations prompt to test the applicability of visual research methods hitherto seldom used in the study of tradition, choosing as the case study the everyday practices of the Song and Dance Celebration movement. The objective of the current research is to establish whether and in what ways the application of visual research methods to the study of tradition advances the understanding of tradition using as the example of tradition the arts groups’ everyday practices during the Song and Dance Celebration interim in Latvia. We pose two central research questions: 1) what everyday practices are typical of the arts groups during the Song and Dance Celebration interim; 2) which aspects of tradition can be explored through visual research methods. The data lead to the conclusion that photo-elicitation is the best visual approach for encouraging reflection on the everyday practices and their motivation. It can be used as the only research method, while the visual data acquired by the researcher need supplementary methods, such as the in-depth interview. Visual data reveal the variety of everyday practices and assist in describing the aspects that are difficult to formulate, e. g., to illustrate emotions and feelings. It is concluded that visual research methods lead to novel and original results, reveal additional everyday practices upholding tradition and open new possibilities for interpreting their significance and symbolism.
“ART BELONGS TO THE PEOPLE!” THE SOVIET CULTURAL POLICY AND ESTONIAN COMMUNITY HOUSES
Authors: Kulbok-Lattik Egge
Published: November 2022

Estonian community houses were built in towns and the countryside by the local people, who had been joining cultural and other societies since the second half of the 19th century. These cultural centres supported the process of building the Estonian state. The space for culture became basis for the lifelong learning system of informal education, which later was regulated and developed according to the politics of culture and education in the Estonian nation-state (1918–40) and the Soviet Union (1940–91). After the invasion of the Baltic States by the Soviet Union in 1940, extensive restructuring or sovietization of the Estonian public administration, economy and culture began. The article examines the sovietization process of Estonian community houses, i.e., how they were turned into the ideological tools of Soviet totalitarian propaganda.

A Navegação Inercial utiliza giroscópios e acelerômetros para manter estimativas de posição de um veículo no qual uma Unidade de Medidas Inercial (conjunto de 3 acelerômetros e 3 giroscópios) está embarcada. Os Sistemas de Navegação Inercial modernos utilizam o filtro de Kalman para calcular estimativas de trajetórias de veículos, o que constitui um sistema de fusão sensorial – nos filtros estocásticos há uma integração das medidas dadas pela UMI com medidas de referência (que são medidas dadas por um outro sensor). Uma aplicação em estudo recentemente é a implementação de Sistemas de Navegação Inercial através de filtros de partículas, que são filtros preditivos destinados à estimação de estados em sistemas, sendo baseados no método de Monte Carlo seqüencial. Estes filtros geram amostras (ou partículas) ponderadas para aproximar uma determinada função densidade de probabilidade. A finalidade deste artigo é aplicar os filtros de partículas e o filtro de Kalman à estimação de trajetórias (através de um experimento automotivo) e apontar as vantagens e desvantagens de cada um destes filtros, comparando ainda o seu desempenho.

Follicular wave emergence and fertility following estrogen based synchronization regimen in anestrus buffaloes (Bubalus bubalis)
Authors: BHAT G R , DHALIWAL G S , GHUMAN S P S , HONPARKHE M , GANDOTRA V K
Published: November 2022

The study was undertaken to study the follicular changes around the time of new wave emergence following estradiol-17ï¢ (E-17) + controlled internal drug release (CIDR) based synchronization in 30 anestrus buffaloes. The animals were divided in two Groups, viz. Group I and II. In Group I (n=20), on day 0 (beginning of experiment), buffaloes were administered CIDR device (1.38 g P4) and concurrently received 1.5 mg estradiol-17ï¢ in 1.5 ml canola oil (i. m.). On day 9, CIDR was removed and a prostaglandin (PG) 2 analogue (500 μg, i. m.) was administered. On day 11, buffaloes were administered gonadotropin releasing hormone (GnRH) analogue (20 μg, i.m.) and inseminated twice at 12 h and 24 h following GnRH injection. Group II (control, n=10) received the CIDR-based protocol except the administration of estradiol at the time of CIDR insert. Ovaries were examined for follicular wave emergence, ovulation of dominant follicles at estrus and subsequent conception at 45 days of insemination. The mean diameter of largest follicle was reduced from 8 mm (0th day) to 4 mm on the day of wave emergence (WE), i.e. day 4 in Group I but day 6 in control. The mean number of 4-5 mm follicle was 5.7 in Group I and 4.8 in control on the days of WE. Ovulation and conception rates achieved were 85 vs 60% and 47 vs 30% respectively. In conclusion the new wave emergence was induced earlier by estradiol-17ï¢ administered along with CIDR which ultimately resulted in more ovulation and conception rate in buffalo. Estrogen based protocols might be adopted to improve fertility in anestrum buffaloes.
Effect of supplementation of red beetroot powder in quail diets
Authors: ÅžENGÃœL A Y
Published: November 2022

This study aims to determine the effects of different levels of supplements (0, 0.5, 1.0 and 1.5%) of red beetroot (B. vulgaris var. rubra L.) powder in the diets of laying quails on productive traits, egg quality, some blood parameters, yolk fatty acid profiles and cholesterol levels. A total of 112, 12-week-old female quails were used in the 4-week study. While the red beetroot powder (RBP) significantly affected egg yield, it was not effective on daily feed intake (DFI), feed conversion ratio (FCR) and egg weight (EW). Among the blood parameters, there were significant differences in terms of the triglyceride (TG), Ca and Na values among the trial groups. In terms of the egg yolk fatty acid profiles, there were significant differences among the palmitic acid and linolenic acid levels of the groups. The results obtained in terms of the egg yolk cholesterol levels showed that the RBP did not significantly affect the cholesterol levels. Consequently, considering its positive effects on some parameters like egg yield, egg yolk colour and palmitic and linolenic acid values, it may be recommended to add RBP to the diets of quails by up to 1%.

Chronic respiratory disease (CRD) caused by Mycoplasma gallisepticum (MG) is one of the major respiratory tract infections of the poultry, resulting in significant economic loss to the poultry farmers. Diagnosis of such ailment is highly necessary for effective control measures. In addition, promising molecular tools are warranted for efficient epidemiological tracing of the outbreaks. The study was focused on the elucidation of phase variable cytadhesin protein gene (pvpA) of MG through cloning and expression analysis. A set of primers targeting the pvpA gene of MG was designed. The complete pvpA gene was amplified and cloned into pUC-derived expression vector pRSETA. Finally, the recombinant clones were examined through colony PCR and restriction endonuclease (RE) analysis with EcoR1 and BamH1 enzymes followed by sequencing. The expression of the recombinant pvpA gene was optimized at 1.4mM/Î¼l concentration of Isopropyl-β-D-thiogalactoside induction at 30Â°C. The recombinant fusion protein was purified by immobilized metal affinity chromatography and characterized by SDS-PAGE followed by confirmation of recombinant cytadhesin fusion protein through western blot analysis. The pvpA gene was successfully cloned and expressed. The deduced amino acid sequence analysis had shown the presence of two direct repeats (DR1 and DR2) along with predicted PRP motifs repeatedly with high proline encoding regions at the carboxy-terminal of pvpA gene indicating its scope for epidemiological studies.

In Indian content of National Agricultural Research and Education System (NARES), agricultural extension connects agricultural research and farmers. Post-graduate teaching in Extension discipline across all agricultural universities prepares students to transfer relevant technologies to farming community and to conduct need-based research by inculcating desired competencies among students. The present study primarily focuses on assessing the overall competency fulfilment level of postgraduate extension students with respect to veterinary extension. The acquisition level of core competencies among students was compared with importance level of respective competencies associated by Livestock Extension professionals. The investigation was based on primary data compiled from 30 livestock extension professionals working in Uttarakhand and 210 postgraduates (M.Sc. and Ph.D.) students across ten agricultural universities of northern India. It was found that ten core competencies related to veterinary extension which were perceived as highly important by Livestock Extension professionals had low acquisition level among students. Out of the ten universities examined for competency fulfilment, only two universities had high level of competency fulfilment while four universities had low level of competency fulfilment. The overall competency fulfilment index of all ten universities was 0.522 indicating a competency fulfilment of just above average with respect to identified 24 competencies. The competency fulfilment index developed can be utilized by agricultural universities for competency mapping of livestock extension professionals and students for further investigations.

Rough lemon (Citrus jambhiri Lush) is one of the leading citrus rootstock around the world besides sour orange. In the present studies, rough lemon was crossed with X 639 and Swingle citrumelo at Department of Fruit Science, PAU Ludhiana during 2015-16. Cent per cent seed germination was recorded for both the crosses under in vitro conditions but, the germination rates with growing media in plug trays were significantly lower (91.3 and 89.2% for RL× X and RL × SC, respectively). Higher proportion of multi-foliate seedlings (26.89%) was recovered by in vitro seed culture over the ex vitro seed germination (5.20%). All the multi-foliate seedlings were confirmed by SSR analysis using two primers (F 29 and F 87). The SSR analysis showed that only 85% multifoliate seedlings were zygotic while, the rest were not confirmed to be zygotic. The SSR analysis of the 50 unifoliate F1 seedlings each from both the crosses with 5 SSR primers differentiated seedlings into two groups, viz. zygotic and nucellar seedlings. In RL × X cross, the most efficient SSR marker was F29, which identified 30% F1 unifoliate seedlings to be zygotic followed by CCSME31, which identified 26% unifoliate seedlings as zygotic seedlings while the remaining seedlings were nucellar. In the cross RL × SC, the primer F29 was most efficient as it identified 28% zygotic seedlings and 72% nucellar seedlings whereas, the primer F87 identified 24 and 76% zygotic and nucellar seedlings, respectively.
An Absence of Time: Remarks on the Temporal Mode of Being in Royal Elamite Inscriptions

Published: November 2022

The surviving royal inscriptions from ancient Elam (in the south and southwest of modern Iran) speak of two historical characters who occupy particular positions outside physical time. These are Šilhaha (probably active in the early nineteenth century BC) and Princess Bar-Uli (in the second half of the twelfth century BC). Šilhaha became a prominent figure in Elamite history. His position is known through a legitimizing formula used by several subsequent rulers who claimed to be the ‘son of Šilhaha’s sister’. Thus, Šilhaha became a sempiternal being as his metaphysical existence was necessary for all the future kings who would make such a claim. However, his temporal mode of being changed from sempiternal to omnitemporal when he appeared in a curse formulated in the late twelfth century BC. In this curse, Šilhaha occupies a divine position. To appear in such a position means that his metaphysical existence would become necessary for the future both within and outside physical time. As for B/Par-Uli, she is called the ‘beloved daughter’ and ‘salvation’ of King Šilhak-Inšušinak I (conventionally 1150-1120 BC). Being her father’s ‘salvation’ denotes her role in this world and the hereafter. Moreover, her image, engraved in a mirror-like scene on a chalcedony bead, further emphasises her position and role. Drawing on the terms ‘temporal’, ‘sempiternal’ and ‘omnitemporal’, this paper examines the textual contexts to see how the shift in the temporal modes of being occurred. In the end, the image on the chalcedony bead will be briefly discussed.

Organophosphorus insecticides such as diazinon (DZN) are used worldwide in industry, veterinary practice, and agriculture. They may induce oxidative stress in different tissues. The use of antioxidants can protect tissues against oxidative stress. The aim of this study was to investigate the prophylactic and therapeutic roles of vitamin E against DZN–induced oxidative damage and biochemical alterations in various tissues of male Wistar rats. Thirty rats were divided into five groups: Control group received only corn oil as DZN solvent, DZN group received 100 mg/kg of DZN, E group received 150 mg/kg of vitamin E, E-DZN group received vitamin E and then dosed with DZN and DZN-E group received DZN and then dosed with vitamin E. All injections were carried out intraperitoneally. Plasma and various tissues were prepared and evaluated. Results showed that acute administration of DZN caused a significant induction of oxidative damage in the tested tissues via increased malondialdehyde level and some plasma biochemical indices, depletion of glutathione (GSH), reduced cholinesterase activity and change in the activities of superoxide dismutase, catalase and glutathione-S transferase. Treatment of rats with vitamin E resulted in an elevation in the level of GSH, normalizing the antioxidant enzymes activities and decreasing lipid peroxidation, although all these tests did not return to the normal level in certain tissues. The findings of this study suggest that both prophylactic and therapeutic treatments of rats with vitamin E provide a protective role against DZN-induced oxidative stress and cholinergic hyperactivity through free radicals scavenging and membrane stabilizing.

Authors: Ramírez Gómez Carlos Julián , Espinosa Holmes Rodriguez , Betancur Fernando Restrepo
Published: November 2022

Background. The current challenges of agrifood chains make it necessary for them to be efficient from the point of view of production. This demands greater attention to the farmer's technological adoption process and to some aspects that may affect it. Objective. In this study a multivariate cluster analysis method was used, with the aim of identifying the influence of a farmer’s profile and their teaching–learning environment on the adoption of technology in avocado farming. Methodology. The investigation was conducted with 94 farmers in two rural municipalities, located in the same rural region. The questionnaire that was used included profile variables, learning styles, farmer learning preferences, and extension agent teaching methods. Results. Three clusters of adopters were formed and the technology adoption index was analyzed in seven categories, including 37 technologies and technological practices. The case study showed that the high adoption cluster included profiles of older farmers with experience and membership to producer organizations; this cluster was also the only group comprising a combination of farmers’ learning styles and preferences. However, the disconnection between an extension agent's teaching methods and the farmers’ learning is evident in all clusters. Implications. Our results provide important evidence regarding the importance of linking the profile, style, and learning preference in contextualized teaching methods, allowing for better development of farmers’ capacities for the adoption of technologies and practices. Conclusions. The analysis of clusters of adopters allowed farmers to be classified into high, medium and low rates of adoption of technology and technological practices. Each cluster presented certain differences in terms of learning styles and preferences, as well as a disconnection in the teaching-learning relationship.
Smallpox prevention in the Austrian Littoral
Authors: Bratož Urška
Published: November 2022

The article discusses vaccination as the key smallpox prophylaxis, used in the Habsburg provinces from the beginning of the nineteenth century onward. The analysis of quantitative data for the Austrian Littoral (particularly Koper and Trieste) also points to the scope and frequency of smallpox epidemics in the second half of the nineteenth century, which raises questions concerning the extent to which these prophylactic measures were implemented and the population’s willingness to heed the calls for immunization. By creating a regulatory framework, the state sought to attain the maximum possible prevalence of this practice, which nevertheless remained the target of various prejudices for a long time to come. The authorities, the Church, and scientists therefore sought to heighten the popular awareness on the need for immunization through a range of communication channels. Because cowpox vaccination failed to ensure lasting immunity, revaccination was of crucial importance, but its implementation was even more limited.

Authors: Kropej Telban Monika
Published: November 2022

The contribution discusses the narrative folklore about the plague, most notably how it spread, how people tried to protect themselves against the disease and how they treated it in Slovenian territory and, to some extent, within the wider European framework. The first part presents the analysis of folktales in which the Plague, personified as a demonic figure, roams from place to place, from one land to another. The second part focuses on steps taken to prevent the disease from spreading and means of protection against it, as well as healing, charms, incantations, and other vernacular practices during the epidemic.
