Cardiovascular Imaging Techniques for Detection of Vulnerable Plaques
Authors: Márton Emese , Cernica Daniel , Țolescu Cosmin , Lupșan Andrada , Chițu Monica , Benedek Imre 
Published: April 2021

Abstract
Various cardiovascular imaging techniques were developed for the detection of vulnerable atherosclerotic plaques, hoping to be able to predict a cardiovascular event. Plaque vulnerability results from compound pathophysiological mechanisms that lead to structural and morphological changes in lesions. The aim of this review is to present the most recent techniques for the assessment of vulnerable coronary plaques such as cardiac computed tomography angiography (CCTA), optical coherence tomography, or virtual histology intravascular ultra-sound, based on literature data from the last 3 years. CCTA permits direct visualization of the intravascular lumen, together with characterization of the arterial wall. Recent studies maintain that low-attenuation plaques, spotty calcifications, positive vessel remodeling, and the napkin-ring sign are considered main markers of plaque vulnerability and instability. Emerging analytical techniques, such as machine learning or radiomics, will probably demonstrate useful as an auxiliary diagnostic tool for vulnerable plaque detection. The data from the two imaging techniques together provide useful information, especially in patients undergoing a PCI procedure for an acute coronary syndrome. Invasive and noninvasive imaging techniques are able to deliver a large amount of scientific data to assess vulnerable coronary atheromatous plaques. Recent studies demonstrated that information defined by the two techniques is complementary, and using both methods is essential for adequate diagnosis, therapeutic strategy, and prognostic assessment.

Published: April 2021

Abstract

Background: Coronavirus disease 2019 (COVID-19) has emerged as a pandemic and public health crisis of an unprecedent effect. Clinical studies reported an association between COVID-19 and cardiovascular disease, whereas COVID-19 itself can induce myocardial injury, arrhythmia, acute coronary syndrome, and venous thromboembolism.

Case summary: A patient diagnosed via screening coronary computed tomography angiography with non-obstructive coronary artery disease was hospitalized with non-ST elevation myocardial infarction and atrial flutter during a severe respiratory infection episode with SARS-CoV-2. After recovery from the infectious episode, fractional flow reserve-guided elective percutaneous coronary intervention with drug-eluting stent was performed.

Conclusions: COVID-19 intercurrence in a cardiovascular patient with nonobstructive coronary artery disease triggered coronary plaque vulnerabilization with subsequent development of an acute coronary syndrome. SARS-CoV-2 proved to be involved via direct viral tissue involvement and concomitant mechanisms derived from systemic illness in the development of a severe supraventricular arrhythmic event.

Abstract
The paper covers the main aspects and restrictions on siting small-scale wind farms in Latvia and benefits of using energy storage systems with small-scale wind farms. The restrictions of siting have been analysed. Grid connection restrictions are addressed as the main issues for small-scale wind farm development in Latvia. Two small-scale wind farm models with similar properties have been made and analysed within the framework of the research. The paper proposes the idea for maximising the production of small-scale wind farm in a small area site with high wind potential.
Liquefied Natural Gas Infrastructure and Prospects for the Use of LNG in the Baltic States and Finland
Authors: Savickis J. , Zemite L. , Jansons L. , Zeltins N. , Bode I. , Ansone A. , Selickis A. , Broks A. , Koposovs A. 
Published: April 2021

Abstract
In the early 2010s, only 23 countries had access to the liquefied natural gas (hereinafter – LNG). Import terminals, despite attractive short-term economics, took long time to build, and rigid supply contracts made truly global use of LNG rather complicated. Concerns about geo-political risks also stunted demand growth from existing supply sources, even when new LNG export routes and sources became available.
Current natural gas market is very different, both in terms of market participants and accessibility and diversity of services. In 2019, the number of LNG importing countries reached 43. Rising competition among suppliers and increasing liquidity of markets themselves created favourable conditions to diversify contract duration, size, and flexibility. In addition, development of floating storage and regasification unit (hereinafter – FSRU) technology provided LNG suppliers with a quick response option to sudden demand fluctuations in regional and local natural gas markets [1].
Moreover, LNG is one of the major options not only for bringing the natural gas to regions where its pipeline supply infrastructure is historically absent, limited or underdeveloped, but also for diversification of the natural gas supply routes and sources in regions with sufficient state of pipeline delivery possibilities. And it concerns smaller natural gas markets, like the Baltic States and Finland as well. Accordingly, prospects for use of LNG there in both mid and long-term perspective must be carefully evaluated, especially in regards to emerging bunkering business in the Baltic Sea aquatory and energy transition in Finland, replacing coal base-load generation with other, more sustainable and environmentally friendly alternatives.
FRASKYV – metode og verktøy i dansekunstneriske prosesser
Authors: Nesse Caroline Wahlström , Myhre Camilla 
Published: April 2021

Abstract
In our work as dance artists we have for many years worked at guiding creative and artistic processes based on body and movement. We have developed didactic models that can be put to use in encounters with both children and young people, as well as students and professional dancers. Our work is based on guiding or coaching starting from the individual’s viewpoint. In these processes it is the individual expression that is being cultivated, always in an artistic context. The work is founded in a phenomenological view of body and movement, with the lived, experienced body as a central concept.
An important part of our work has been about developing models and tools where physical principles, understanding of shape, expression, space and composition, can be seen in relation to the individual’s creative and artistic process. Through this a need has arisen to find new words and terms that can explain artistic processes in a more overall way and where the development of bodily knowledge is not separated from the artistic processes.
In this context we have found a new word, “fraskyv”, that could be understood as the opposite of gravitation, like a push-off, some kind of upward pull, a spring, momentum, or maybe as a shift of weight, transfer or a change in a wider sense. The point has been to find a word that can contain both technical and creative elements, and this word “fraskyv” is the starting point for this article.
Kunsten at pille et løg:
Authors: Daugaard Kasper , Ørum Amalie 
Published: April 2021

Abstract
To peel an onion, to grate a carrot, and to set a table, each has its own choreographic recipe. Culinary art/ cookery is choreographed everyday life, and cooking is a dance everyone knows.

The Art of Peeling an Onion is based on the dance piece Gæst (Guest), choreographed by Kasper Daugaard. The piece is for five dancers, a female soloist and four choir dancers, and originates entirely from culinary actions. The purpose of the article is not to maintain theory and practice as two separate entities, but to show how they supply each other and offer each other content. We aim to create a balanced understanding of the relationship between the creative process, the audience experience, and the aesthetic theory related to both the content and the outcome of artistic work. We view theory and practice hand in hand, because we have strived to put into words that which can be experienced, to verbalise the spectator’s experiences, the physical as well as reflexive, with the ambition of formulating a quite tangible experience-based aesthetics.
Et fast greb i rebet – om Claras levede erfaringer som nycirkus artistelev
Authors: Degerbøl Stine 
Published: April 2021

Abstract
The article concerns the lived experiences of Clara practicing to become a contemporary circus artist. Clara’s narratives reflect contemporary circus as a movement pedagogical practice in relation to theories about aesthetic learning and in relation to the aims of a circus performer education in Copenhagen, Denmark. Furthermore her narratives provide a discussion of educational settings on the fringe of ordinary youth education. Firstly contemporary circus is presented as a counterculture to the traditional circus and secondly it describes how the development of contemporary circus as an art form influenced the establishment of contemporary circus schools. Body phenomenology and narrativity are the main theoretical and methodological inspirations for reflections about aesthetic learning processes taking point of departure in Clara as a case.
The Embodied Teaching Moment:
Authors: Østern Tone Pernille 
Published: April 2021

Abstract
In this article the author dialogues with two contemporary dance teachers about how the practical-pedagogical knowledge of the teacher is embodied. The focus is on how the dance teacher functions as a lived body (Merleau-Ponty, 1962/2002) while in the teaching moment. The analysis of the empirical material shows that there is a continuous exchange between the dance teachers’ bodily experiences, inner dialogue and teaching choices while teaching. It is argued that its is not wrong to say that all these two dance teachers do as teachers is bodily grounded. The ways in which the practical-pedagogical knowledge of the two contemporary dance teachers is embodied can be summarized as a bodily listening, bodily tutoring and bodily ambiguity surrounded by constantly and rapidly changing body tunes throughout their teaching. These larger themes are divided into nuances which are presented and discussed in the article. The study is also a method study in how to study in and with the arts. The research process is understood as an iterative cyclic web (Smith and Dean 2009), where practice and theory take place in every sub-process of the study. Outcomes of the study are both theorisation as this article and artwork in the form of choreographies by the two dance teachers. These can be seen at

Published: April 2021

Abstract

Introduction. Migraine is a common debilitating disorder of neurovascular origin which affects younger adults, especially women.

Material and Methods. It was an experimental study design. A convenience type of sampling was used for recruitment of the subjects. A total of 21 participants diagnosed with migraine (6 males and 15 females) fulfilling the inclusion criteria were taken for this study and assigned to one of the two groups (experimental or control group). PFT measured with PFT apparatus (Spirolab 111, Serial No. A23-053 13974) and HDI score were calculated before the start of the intervention and after the intervention. Afterwards, PFT was performed by each participant followed by HVLA thrust manipulations to the migraine patients and an equal period of rest to the control group.

Results. There are no significant differences between baseline and post-intervention outcome variables and in mean changes between the two groups. One-way ANOVA was used to analyze the change in HDI score which was calculated three times (pre- prior to intervention, post- after the intervention and 1 month after the intervention). The experimental group showed a significant reduction in the score after the manipulation. It was found that FVC and PEF were positively correlated to FEV1, and FVC was also positively correlated to PEF.

Conclusions. The findings of the study revealed that high-velocity thrust manipulations of upper cervical spine were not effective in improving pulmonary functions of migraine patients although it was found effective in improving subjective symptoms of the patients evaluated through HDI.
Adrenal vein sampling for primary aldosteronism: a 15-year national referral center experience
Authors: Kocjan Tomaz , Jensterle Mojca , Vidmar Gaj , Vrckovnik Rok , Berden Pavel , Stankovic Milenko 
Published: April 2021

Abstract

Background
Adrenal vein sampling (AVS) is essential for diagnostics of primary aldosteronism, distinguishing unilateral from bilateral disease and determining treatment options. We reviewed the performance of AVS for primary aldosteronism at our center during first 15 years, comparing the initial period to the period after the introduction of a dedicated radiologist. Additionally, AVS outcomes were checked against CT findings and the proportion of operated patients with proven unilateral disease was estimated.

Patients and methods
A retrospective cross-sectional study conducted at the national endocrine referral center included all patients with primary aldosteronism who underwent AVS after its introduction in 2004 until the end of 2018. AVS was performed sequentially during Synacthen infusion. When the ratio of cortisol concentrations from adrenal vein and inferior vena cava was at least 5, AVS was considered successful.

Results
Data from 235 patients were examined (168 men; age 32–73, median 56 years; BMI 18–48, median 30.4 kg/ m2). Average number of annual AVS procedures increased from 7 in the 2004–2011 period to 29 in the 2012–2018 period (p < 0.001). AVS had to be repeated in 10% of procedures; it was successful in 77% of procedures and 86% of patients. The proportion of patients with successful AVS (92% in 2012–2018 vs. 66% in 2004–2011, p < 0.001) and of successful AVS procedures (82% vs. 61%, p < 0.001) was statistically significantly higher in the recent period.

Conclusions
Number of AVS procedures and success rate at our center increased over time. Introduction of a dedicated radiologist and technical advance expanded and improved the AVS practice.

THROUGH THE LENS OF A WOMAN WITH SCHIZOAFFECTIVE DISORDER: A CASE STUDY
Authors: Trifu Simona , Șerban Emilia , Serdaroglu Meryem , Soare Naomi Evelina 
Published: April 2021

Motivation/Background: Historically speaking, the distinction between manic-depressive disorders and schizophrenia finds itself in an unclear and vast spectrum bordered by the two illnesses. In this paper, we will present a case study that raises a question of diagnosis: bipolar disorder or schizoaffective disorder? Following the description of the symptoms and diagnosis criteria of each of the disorders, along with the personal data of the patient (the ones that are available to us), we will attempt analyzing the case as thoroughly as possible. The paper introduces the case of a 40-year-old woman who presents affective/mood related symptoms.
Method: psychiatric evaluation, psychiatric interview, psychodynamic interview and psychodynamic interpretation.
Results: The subject has a pathology of attachment developed over a structure with homosexual attachment choices. The multiple psychotraumas of childhood and the busy life history overlap with a vulnerability for emotional manifestations. She develops as axis I pathology a bipolar affective disorder, which at the moment takes the form of a mixed dispositional episode with psychotic phenomena. The artistic side makes it work markedly on delirious interpretativity, as it is to be appreciated the patient's effort not to completely detach from reality.
Conclusions: Late detection of these habits by the relatives, as well as other signs of psychiatric conditions, has contributed to an alteration of the identity of the patient and an inability to develop proper social behavior. After an overview of the patient's life experience, we can presume that the psychiatric condition is present and that it is evolving. The aim of the paper is to provide a theoretical viewpoint on this specific pathology, with particular features for this case study
Lutar, esconder ou correr: como <em>Tamandua tetradactyla</em> (Mammalia) em cativeiro responde a pistas indiretas de um predador?

<p>No ambiente natural, os animais são expostos a uma grande quantidade de ameaças a sobrevivência. Considerar a ecologia do medo é importante para estimar o papel ecossistêmico que os predadores desempenham nas comunidades, uma vez que o medo de um predador pode provocar não somente respostas baseadas em densidade (<em>i.e</em>., remoção de indivíduos de uma população), como também respostas comportamentais, que podem resultar em efeitos em cascata. Comportamentos defensivos são relativamente simples de serem avaliados em situação de cativeiro, uma vez que são conspícuos e específicos, dificilmente sendo confundidos com outros comportamentos quando observados. Desta forma, o objetivo deste estudo foi verificar a habilidade de indivíduos de <em>Tamandua </em><em>tetradactyla</em> (Linnaeus, 1758) em detectar pistas indiretas de um predador, para avaliação de risco do ambiente. Neste estudo, seis indivíduos de tamanduás-mirim (<em>T. tetradactyla</em>) em cativeiro foram expostos a pistas indiretas (<em>e.g</em>., urina e fezes) de jaguatirica (<em>Leopardus pardalis</em>). No total, cinco machos e uma fêmea de tamanduá foram observados pelo método de animal focal, em um esforço total de 36 horas de observação. Tamanduás-mirins alocados nos recintos com pistas indiretas do predador exibiram maior frequência de comportamentos anti-predatórios e diminuição dos comportamentos de inatividade. A utilização de pistas indiretas é vantajosa para indivíduos de tamanduá-mirim, pois permitem a avaliação de risco de uma determinada mancha do ambiente e elicia comportamentos de evitação, que são menos custosos energeticamente. A porcentagem de comportamentos também é apresentada com e sem as pistas indiretas do predador de <em>T. tetradactyla</em>, na qual pode ser útil para entender a capacidade de resposta de tamanduás-mirins a situações de perigo.<strong></strong></p><p><strong></strong><strong>Palavras chave</strong>: Ecologia do medo, tamanduá-mirim, jaguatirica, comportamentos anti-predatórios.</p>
CONDUCTION MECHANISM AND CONDUCTIVITY BEHAVIOUR OF PURE POLYPROPYLENE (PP) AND POLYPROPYLENE-BANANA FIBER (PP-B ) COMPOSITES
Authors: Islam Nazrul , Gafur M.A , Khan Amir Hossain 
Published: April 2021

Fibers reinforced composite materials offer a combination of strength and modulus that are either comparable to or better than many traditional metallic materials. The research on natural fiber based composite materials fit well into this ecological image. This paper reports the conduction mechanism and ac conductivity, activation energy behavior of Polypropylene and banana fiber reinforced thermoplastic composites. Polypropylene [-CH2-CH2-CH2-]n and different fiber content (wt. %) of polypropylene-banana fibers (natural fiber) composites were fabricated using a hot-press molding system. The optimum fabrication parameters were established (initial pressure, temp. etc.). These composite test samples were fabricated so the short fibers were randomly oriented in the matrix. The detail investigation of the a. c. conductivity and conduction mechanism of polymer composites would provide information about the relaxation processes, activation energy etc. which are dependent on frequency, temperature and time. The activation energy involved in the above processes can also be estimated from this study. The measurements were performed over a wide range of frequency of 60 Hz to 3 MHz and temperature range from 30°C (303°K) to 110°C (383°K). Experimental results of the ac properties of pure polypropylene and polypropylene-natural banana fiber composites were compared. It has been established that the fabricated composition changes its insulating property after adding the natural fibers and gives the better conductivity properties.
