The aim of the study was to evaluate the efficacy of ketamine, dexmedetomidine, atipamezole and alfaxalone delivered by two methods of intranasal administration in terrapins. The two methods were used in 21 healthy adult female red-eared terrapins: (A) with fully extended neck and restrained head, (B) with head hidden inside the shell. Ketamine (10 mg/kg) and dexmedetomidine (0.2 mg/kg) were delivered using a micropipette in the left and the right naris, respectively. Atipamezole (2 mg/kg) was administered 60 minutes later. Heart rate, head withdrawal reflex, palpebral reflex, toe-pinch reflex on the pelvic limb and glottal control enabling the insertion of the tracheal tube were recorded at 10-minute intervals. After a washout period of six months, alfaxalone (5 mg/kg) was tested. The first measurement in the alfaxalone trial started 5 minutes after the drug was administered and continued at 10-minute intervals. Heart rate decreased significantly in response to both methods of ketamine and dexmedetomidine administration. There were no significant differences between methods in time to loss of reflexes and full recovery of reflexes. Intranasal administration of atipamezole enabled rapid return to full activity. Alfaxalone administration decreased heart rate non-significantly and did not result in loss of evaluated reflexes. Both methods of drug administration of ketamine, dexmedetomidine and atipamezole resulted in a safe form of sedation and recovery. Intranasal administration of 5 mg/kg of alfaxalone was not effective.

Inefficient heat use in old multi-flat residential buildings causes problems to the residents spending a large part of their incomes on heat bills as well as for the State working towards achieving goals of energy efficiency increase, climate change mitigation and energy security. However, the Lithuanian program of multi-flat building renovation keeps stalling, and therefore danger that much of this energy saving potential will go unrealised appears. The paper is concerned with the problems that arise when renovating multi-flat buildings according to the existing legislation. In this case, the emphasis is placed on the factors that have influence on decisions made by building owners to either participate or not in the renovation program. The paper demonstrates that the currently employed method of evaluating building renovation projects does not correctly reflect the benefits of refurbishment and gives financially unattractive financial indicators. Thus, the new method of investment distribution is introduced considering three aspects of benefits for building renovation. The case analysed demonstrates how the suggested “ternary benefit” method could be used for differentiating between financing sources and presenting relevant information to the building owners. Another related problem is heat saving assessment in the building refurbishment process. The paper argues that energy audits are far more suitable for the evaluation of modernisation projects than for energy performance certification. Santrauka Neefektyvus šilumos vartojimas senuose daugiabučiuose pastatuose yra opi problema tiek didelę dalį savo pajamų šildymo išlaidoms skiriantiems gyventojams, tiek valstybei siekiant didinti energijos efektyvumą, mažinti klimato kaitą ir energinės nepriklausomybės tikslų. Tačiau daugiabučių namų modernizavimo programa vis stringa ir kyla grėsmė, kad energijos taupymo potencialas artimiausiu metu nebus realizuotas. Analizuojant modernizavimo procese kylančias problemas ir ieškant jų sprendimo, šiame straipsnyje analizuojama dabartiniu metu taikoma daugiabučių namų modernizavimo projektų vertinimo metodika. Dėmesys sutelkiamas ties veiksniais, lemiančiais pastato savininkų apsisprendimą dalyvauti modernizacijos projekte, tokiais kaip modernizavimo projekto finansinis patrauklumas. Viena iš svarbių daugiabučių namų modernizavimo procesą stabdančių problemų yra dabartinis modernizavimo projektų vertinimo metodas. Pirma, šis metodas neatspindi trejopos renovacijos naudos pastato savininkams. Antra, taikomas šilumos taupymo prognozavimo metodas yra nepakankamai patikimas. Straipsnyje siūloma vietoje įprasto renovacijos projektų vertinimo metodo taikyti „trejopos naudos“ metodą. Šis metodas atskleidžia renovacijai reikalingų investicijų pasiskirstymą pagal sukuriamą naudą. Tokiu būdu galima diferencijuoti renovacijos finansavimo šaltinius, suteikti išsamios informacijos pastato savininkams. Straipsnyje aprašomas atliktas konkretaus tipinio daugiabučio namo modernizavimo projekto vertinimas įprastiniu ir „trejopos naudos“ metodu. Palyginimo rezultatai rodo, kad, visas investicijas nepagrįstai priskiriant energijos efektyvumo priemonėms, renovacijos projektai tampa nepatrauklūs daugiabučių pastatų savininkams.

Eight out of ten Spaniards think the hole in the ozone layer, caused by human actions, is the key physical cause of climate change. This belief, constructed from scientific elements (concepts, images, icons, discourse), is a product of popular culture. Science has never confirmed this relationship. It was the ability of popular culture to incorporate scientific «objects» according to its own epistemology that established and popularised the idea until it became a global cultural belief. The divergence between social and scientific representation invites us to reflect upon how contemporary societies embrace and remodel scientific culture to construct representations for interpreting reality and directing responses (or inaction) to threats identified by science.

By the end of 2018 we learned about the birth of two twins that had been genetically engineered using CRISPR to be immune to HIV. Despite the doubts regarding the veracity of the claims of the Chinese scientist in charge of the project, the news confirmed the urgent need to open a debate on the ethical, legal, and social dimensions of genetics, but also on other scientific advances that will undoubtedly impact our lives directly in the near future.
From Mètode Science Studies Journal we have always been committed to opening a space for science reflection and debate, which must provide society with the necessary tools to have an informed understanding to serve as a starting point when making decisions. These pages include a monograph focusing on the communication of biotechnology, which deals with how advances such as CRISPR, the use of animals in research, and biotechnological applications have been explained to society.
Biotechnology is not the only scientific breakthrough that will have consequences for our lives. The development of artificial intelligence in the fields of security, medicine, or transport makes it necessary to reflect on the application of these advances in our daily lives as well, as outlined in another of the special monographs in this volume.
Finally, the present issue of Mètode SSJ also includes a monograph on the concept of biodiversity. A new term to describe the era we are living at the moment, the Anthropocene, has been suggested. It is characterised by the deep footprint humans are leaving in the environment.
Once again, a few pages in which to reflect, analyse, and debate, a new opportunity to build a better science from the ground up.

This diploma thesis is proposing and evaluating a strategy of human resource management in the field of productivity of intellectual workers and students while using insights from scientific research on procrastination and productivity. The suggested strategy implements especially two methods that were found effective for lowering the rate of procrastination in latest scientific studies – the method of awareness and mindfulness and the method of journaling. This diploma thesis includes design and creation of an educational program consisting of video lessons in the field of time-management, techniques of mindfulness and awareness and the method of journaling. Furthermore, it includes running research with a group of students during an exam period, while all participants record information on using the above mentioned methods for the period of 15 days, while the logged information has combined nature between objective information on performance (data on usage of personal computer, data on the amount of work done and time spent on it) and self-evaluation information (subjective evaluation of daily performance and subjective evaluation of perceived daily happiness). This thesis evaluates the suggested strategy on the research sample of 15 university students and is using the methods of input and output questionnaire, same as analysis of the continuous data logged while journaling from the research participants, to evaluate the effectiveness of the proposed strategy. The goal is to be able to apply this strategy in the business practice in human resource management. Another possible application is also improvement of study productivity of students using self-management techniques.

The desire to influence ones opponent without using violence, has probably existed in all times. Reflexive control is a method used historically without the user knowing about the concept, but through research during the 1900s, theories from psychology, behavioral science and cybernetics entered into the military application of modern influence operations. Reflexive control builds upon the fact that a stimulated organism responds with a reflex. Which, in the context of the essay, means that a controller transfers prepared information to a partner or a counterpart to bring him to single-handedly take one of the controller intended decision. This is expressed either by methods used intuitively by an intelligent user or systematically by a controller with knowledge and resources, creating a situation which voluntarily brings or forces the other part to make decisions as the controller wants for its own use. The methods are based on knowledge of the other part's self-image. A self-image that can be individual, for example, a president, or a group, such as a state leadership. The reflex may contain of a decision or of an action that are not well considered but that benefits the controller. The controller then exploits the new situation created by its preparations that may have been on going for a long time. The essay describes some of the methods that has been used by the Soviet Union and later integrated into the Russian warfare. The essay askes the questions; Can Bismarck's actions in 1870 and Russia's actions in the Georgia conflict in 2008 be explained by the theory of reflexive control? Is there a difference? If it is - how is the difference expressed? Yes, both cases reflect reflexive control. The differences between them are explained by the evolution from intuitive actions into systematic use.

Resumo: As áreas de estudo desta pesquisa envolveram rochas pertencentes ao Grupo Itararé - Bacia do Paraná, localizadas em afloramentos nas cidades de Ponta Grossa (próximo ao parque estadual de Vila Velha) e Lapa, ambas no estado do Paraná. O principal objetivo foi a descrição de uma seqüência metodológica que utilizou várias técnicas como: mapeamento geológico, aquisição e processamento de dados de sísmica de reflexão rasa, ensaio geoestatístico com as amplitudes sísmicas e a geração de volumes sísmicos. Foi necessária a adoção de duas áreas de estudo para contemplar as principais etapas do desenvolvimento metodológico proposto, com enfoque geológico na Lapa e geofísico em Vila Velha. Os principais litotipos mapeados na Lapa foram arenitos, diamictitos, conglomerados e folhelhos descritos no mapa geológico. A resposta geofísica deste local não atingiu os resultados esperados, foram encontrados poucos refletores, sendo necessária a aquisição de dados geofísicos em outra porção correlata, no caso a área de Ponta Grossa. A investigação geológica na Lapa gerou o conhecimento das principais variações litológicas na Serra do Monge, assim como o mapeamento destas. Foram definidas cinco unidades litológicas com base no litotipo predominante e posição estratigráfica. Os principais lineamentos estruturais foram correlacionados com grandes feições presentes em escala de bacia definidos por trabalhos anteriores. Também foram investigadas falhas e fraturas em escala de afloramento. Na região próxima ao Parque de Vila Velha foram realizados levantamentos sísmicos de reflexão visando alvos rasos, até aproximadamente 250 metros de profundidade. O resultado foi o imageamento do substrato, incluindo uma correlação com as associações litológicas e falhas visíveis em campo. Os ensaios sísmicos de calibração e parametrização realizados em ambas as áreas de estudo foram essenciais para a solução de diversos problemas, como a fixação de geofones em rocha, geometria dos arranjos e posicionamento da fonte sísmica. No processamento dos dados sísmicos foram executados exaustivos testes que resultaram em seções de boa qualidade na área de Ponta Grossa e ainda pouco refinadas na área da Lapa. Os principais processos numéricos que contribuíram para melhorar as seções sísmicas foram a deconvolução preditiva, filtragem de freqüências e o emudecimento das primeiras quebras. A técnica CDP (common depth point) foi utilizada através da análise de velocidade CVS (Constant velocity stack) e correção NMO (normal move out). Através da construção de semivariogramas, o ensaio geoestatístico demonstrou a provável dependência espacial das amplitudes sísmicas, sendo possível a transformação de dados 2D em uma informação volumétrica para uma interpretação tridimensional. O ensaio geoestatístico demonstrou que a técnica pode ser utilizada com dados sísmicos, como visualizado pelo patamar bem definido em alguns semivariogramas, principalmente nas buscas das amostras realizadas em azimutes paralelos à direção de levantamento das linhas sísmicas. Foi executado um teste na geração de um cubo sísmico preliminar visando à correlação deste com informações geológicas extraídas de fotografias aéreas.

Resumo: O método Common Reflection Surface (CRS) tem por objetivo a obtenção de seções empilhadas de qualidade e extração de parâmetros do campo de onda que caracterizam o meio geológico, através de análises de coerência e com máxima utilização da redundância contida nos dados sísmicos de multicobertura. Para a realização dessas finalidades, o método CRS utiliza "famílias" de pares de fontes e receptores arbitrariamente dispostos em torno de um ponto central e empilhamentos através de tempos de trânsito multi-paramétricos. O CRS representa um significativo aprimoramento do clássico método Common midpoint (CMP), o qual utiliza famílias de pares fonte e receptor simetricamente dispostos em torno do ponto central (denominadas famílias CMP). Além disso, o número maior de parâmetros CRS permite melhores informações sobre o meio geológico. Neste trabalho, discutimos os fundamentos e principais resultados do método CRS na situação 2D, comparando-o ao método CMP. Dentre os vários estudos e aperfeiçoamentos realizados no método CRS, destacam-se (a) nova implementação do programa CRS, com utilização de parâmetros diretamente advindos dos dados; (b) implementação conjunta dos métodos CRS e CMP visando melhor contribuição de cada um deles para o imageamento sísmico; (c) introdução de nova metodologia para eliminação ou tenuação de ruído alinhado nas seções CRS e (d) investigação qualitativa e quantitativa das resoluções vertical e lateral do método CRS.
Abstract: The Common Reflection Surface (CRS) method is designed to produce stacked sections of superior quality, as well as a number of useful wavefield attributes that caracterize the geological subsurface. These attributes are estimated by means of coherency analysis methods, which optimally exploit the redundancy contained in the multicoverge seismic data. To take advantage of this redundancy, the CRS method employs "gathers" of source and receiver pairs, arbitrarily located around a fixed central point, with the help of multi-parametric traveltime moveouts. Waving the restriction of symmetric source-receiver pairs around the central point allows full use of the multicoverage data. As a result, CRS stacked sections are seen to be cleaner, with better signal-tonoise ratio and continuity of reflection events. We discuss the basics and main results of the CRS method, in the 2D situation, in close comparison with the classical CMP method. A number of improvements on the method itself, as well as on its practical applications, are presented. These include (a) a new implementation of CRS, with the use of parameters most directly related to the input data; (b) joint use of CRS and CMP, with the aim of obtaining the best possible processing and imaging results; (c) introduction of a new methodology to eliminate or attenuate aligned noise and (d) qualitative and quantitative investigation on vertical and lateral resolution in CRS sections.

Resumo: Aplicado a dados de multicobertura, o método da Superfície Comum de Reflexão (CRS) obtém, além de uma seção empilhada mais limpa e bem definida, uma série de parâmetros ou atributos da equação do tempo de trânsito definidos em cada ponto da seção de afastamento nulo. Os parâmetros da equação do tempo de trânsito proporcionam informação útil para uma variedade de processos sísmicos. Aqui, investigamos o papel dos atributos CRS na importante tarefa de identificar e atenuar reflexões múltiplas. Consideramos a situação 2D na qual o método CRS fornece três parâmetros, a saber, o ângulo de emergência do raio normal e os raios de curvatura das frentes de ondas associadas a duas ondas fictícias, denominadas onda N e onda NIP. Essas abreviações significam onda normal (N) e onda de ponto de incidência normal (NIP). Nesta dissertação apresentamos e discutimos um algoritmo desenvolvido para identificar os atributos CRS de reflexões múltiplas e, num próximo estágio, atenuar ou eliminar a energia, não desejada, deste tipo de evento. Os atributos CRS das múltiplas são obtidos, segundo relações encontradas, a partir dos correspondentes atributos das primárias. Primeiros experimentos mostram que estes algoritmos têm potencial favorável de substituir consagrados métodos de supressão
Abstract: Applied to multicoverage data, the Common-Reflection-Surface (CRS) method obtains, besides a c1ear and well-defined stacked section, also a number of traveltime attributes defined at each point of that zero-offset (stacked) section. The CRS traveltime parameters provide useful information for a variety of seismic processing purposes. Here we investigate the role of CRS attributes in the important task of multiple identification and attenuation. We consider the 2D situation in which the CRS method produces three parameters associated to the propagation of the wave front, namely, the angle of emergency of the normal ray and radii of curvature of the so-called N and NIP wavefronts. The abbreviations N and NIP stand for normal and normal-incident-point waves, respectively. We propose and discuss simple algorithms designed to identify the CRS attributes of the multiple reflections and, as a next stage, to attenuate or eliminate the energy of this type of un desirable evento The CRS attributes of the multiple are obtained, according to relations found, from the corresponding attributes of primary events. First experiments show that the these algorithms have the potential of favorably replace well-established multiple suppression methods

Resumo: O método CRS (do Inglês "Common Reflection Surface"), introduzido por Peter Hubral em 1997, é uma técnica alternativa ao convencional empilhamento CMP. O empilhamento CRS é capaz de fornecer não apenas uma melhoria nas seções simuladas de afastamento nulo (ZO), mas também um trio de parâmetros que extraem mais informações sobre a propagação do meio do que o único parâmetro do clássico método CMP, a velocidade NMO. O objetivo deste trabalho é analisar o potencial do método CRS em produzir modelos de velocidades sísmicas, analogamente para a computação da velocidade NMO no método CMP. Nós descrevemos os métodos CMP e CRS e comparamos suas performances sobre ilustrações sintéticas e exemplos de dados reais.
Abstract: The Common Reflection Surface (CRS) method, introduced by Peter Hubral in 1997, is an alternative technique to the conventional CMP stacking. The CRS stack is able to provide not only improved simulated zero-offset sections, but also a set of parameters that convey more information of the propagating medium than the single NMO-velocity parameter of the classical CMP method. The objective of this work is to analyze the potential of the CRS method to produce seismic velocity models, analogously to the computation of the NMO velocities in the CMP method. We review the CMP and CRS methods, and compare their performances on illustrative synthetic and real data examples.

Resumo: A maioria dos métodos de imageamento de subsuperfície aplicados em projetos de Exploração e Produção (E&P) de hidrocarbonetos assume o meio elástico isotrópico (ISO). Os meios isotrópicos, em contrapartida aos modelos anisotrópicos, são aqueles cujas velocidades das ondas sísmicas não dependem da direção de propagação. Entretanto, muitas rochas obtidas de testemunhos apresentam anisotropia. Logo, é natural que estudos dos meios anisotrópicos sejam feitos com o intuito de aumentar a precisão do imageamento sísmico. As anisotropias são classificadas de acordo com as simetrias apresentadas. As simetrias mais comuns em exploração de hidrocarbonetos são as simetrias transversalmente isotrópicas (TI) e ortorrômbicas (ORT). Quando uma onda impinge uma interface são geradas ondas refletidas e transmitidas. A razão entre as amplitudes dos vetores de deslocamento da onda incidente em relação às ondas geradas são os coeficientes de reflexão/ transmissão (R/T) de deslocamento. Os coeficientes R/T podem ser expressos explicitamente por fórmulas apenas em casos de alta simetria, por exemplo, isotrópica. Caso contrário os coeficientes R/T devem ser obtidos de um sistema de equações algébricas lineares obtidas das condições de contorno na interface. Neste trabalho desenvolvemos um código para calcular os coeficientes de reflexão e transmissão (R/T) para interfaces entre meios anisotrópicos. Dois critérios para a distinção das ondas geradas na interface são adotados em adição ao critério convencional da literatura. As simetrias utilizadas para os testes sintéticos foram as simetrias ISO, TI e ORT. O testes exemplificam algumas características básicas dos coeficientes R/T, como equivalência entre interfaces e simetrias inclinadas e a reciprocidade dos coeficientes normalizados pela energia
Abstract: The great majority of the methods for imaging subsurface invested in hydrocarbons Exploration and Production (E&P) assumes isotropic elastic medium (ISO). The isotropic models are those which velocities of seismic waves do not depend on the direction of propagation. However many core rocks exhibit anisotropy. Thus, the assumption of anisotropic media is natural in order to increase the accuracy of seismic imaging. The anisotropies are classified according to their symmetries. The most common symmetries in hydrocarbon E&P are the transversely isotropic (TI) and orthorhombic (ORT) symmetries. When a seismic wave impinges at an interface between two media, it generates reflected and transmitted waves. The ratio between the amplitudes of displacement vectors of the incident and the generated waves are the displacement reflection/transmission (R/T) coefficients. The R/T coefficients can be expressed by explicit formulas in cases of higher symmetries, e.g. isotropy. Otherwise they are obtained numerically from a system of inhomogeneous linear algebraic equations derived from the boundary conditions in the interface. We develop a code to evaluate the R/T coefficients interfaces between two anisotropic media. We adopt two criteria in addition to the conventional one for distinguishing the generated waves. The symmetries used for the synthetic tests were symmetries ISO, TI and ORT. The tests illustrate some basic characteristics of the R/T coefficients, as equivalence between tilted symmetries and interfaces, and the reciprocal of the energy normalized R/T coefficients

Resumo: A demanda por multiplicidade no processamento sísmico sempre foi objetivo dos profissionais da área. Até recentemente, o maior esforço era feito durante a aquisição sísmica, o que, devido aos altos custos, normalmente tornava proibitiva sua implementação. Mais recentemente, a técnica Superfície Comum de Reflexão ou Common Reflection Surface (CRS), veio preencher esta lacuna, uma vez que, a despeito de maior custo computacional relativamente aos procedimentos convencionais, é capaz de propiciar grandes multiplicidades, sendo esta a sua mais evidente e conhecida virtude. Mais ainda, associado a este ganho na multiplicidade, o método CRS permite também a possibilidade de alcanc¸armos melhores resolucões verticais através do empilhamento. Isto pode ser obtido através do incremento da chamada frequência crítica, na qual a razãosinal-ruído é igual à unidade (s/r = 1). Desde que isto seja alcançado, podemos obter o aplainamento do espectro de freqüência por técnicas convencionais. Neste trabalho, mostraremos quantitativamente que isto pode ser feito, como a freqüencia crítica está relacionada à multiplicidade e porque apenas técnicas que possibilitem grandes multiplicidades podem efetivamente fazer com que esta freqüência se desloque para maiores valores. Mostraremos tamb'em que os ganhos obtidos compensam o esforço exigido. Como já fartamente documentado na literatura geofísica, a aplicação do método CRS dá origem a atributos (denominados simplesmente de parâmetros CRS), os quais podem trazer preciosas informações geológicas. Aqui mostraremos como estas informações podem ser usadas para xiii o imageamento sísmico, através do conceito de mapas geométricos, conceito este introduzido neste trabalho. Veremos como gerar estes mapas e a série de produtos que podem ser obtidos a partir deles, a saber: campo de velocidades para migração; migração pré-empilhamento em tempo com operador curto; mapeamento dos ápices das difrações reais e conversão tempo-profundidade a partir de seções de coordenadas em afastamento nulo, usando o raio normal. Mostraremos também que, mesmo na presença de descontinuidades, poderemos "colapsar" as difrações, gerando painéis de amplitudes verdadeiras em profundidade. Por fim, analisaremos os efeitos do empilhamento CRS na resolução lateral das imagens obtidas. Fazendo uso dos mapas, apresentaremos formas de inibir perdas de resolucão lateral em situações envolvendo pontos de descontinuidades
Abstract: The demand for large multiplicities in seismic processing has always been a tough target for the professionals involved in this area. Until recently, the major effort to meet this demand has been done during seismic acquisition, which, due to high cost, is not usually implemented. Recently, the Common Reflection Surface (CRS) technique filled this gap providing greater multiplicity on the expense of more intensive computation, when compared with conventional procedures. Besides a greater multiplicity, the CRS technique enables the improvement of the vertical resolution through the CRS stack. This improvement is achieved by means of increasing a specific frequency which we call "critical frequency". At the critical frequency, the signal-to-noise rate is equal to one (s=n = 1). Once the critical frequency is increased, the frequency spectrum can be flattened by usual techniques. In this thesis, we quantify the improvement of the critical frequency as a function of increasing multiplicity and show why only techniques that allow for high multiplicities can achieve this improvement. We will also show that the gain obtained through this procedure is worth the effort. As it is well known in the geophysical literature, the use of the CRS method provides some parameters (usually called CRS parameters) that provide useful information on the seismic propagation involved. Here we show how this information can be optimally used for imaging purposes through the concept of "geometric maps". We show how to generate these maps, as well as, a few "products" derived from them, such as time migrated velocity field, pre-stack time migration using a short operator, real diffraction apex mapping, a true amplitude zero offset section and the conversion of that section to depth using the normal ray. Next, we show that, even in the presence of discontinuity, we can collapse the real diffractions that are present in the data and, furthermore, to construct true-amplitudes panels in depth. Finally, we use the geometric maps to study the effect of the CRS stack on the seismic lateral resolution, especially on the vicinity of discontinuities

A walk suspended in mid-air, a fall at breakneck speed towards a fatal impact with the ground, an upside-down flip into space, the drift of an astronaut in the void… Analysing a wide range of films, this book brings to light a series of recurrent aesthetic motifs through which contemporary cinema destabilizes and then restores the spectator’s sense of equilibrium. The ‘tensive motifs’ of acrobatics, fall, impact, overturning, and drift reflect our fears and dreams, and offer imaginary forms of transcendence of the limits of our human condition, along with an awareness of their insurmountable nature. Adopting the approach of ‘Neurofilmology’—an interdisciplinary method that puts filmology, perceptual psychology, philosophy of mind, and cognitive neuroscience into dialogue—, this book implements the paradigm of embodied cognition in a new ecological epistemology of the moving-image experience.

This publication results from the research work undertaken by the partner institutions involved in the KA3-ICT Project Transversal Lifelong Learning Programme, Learn about finding jobs from digital storytelling(143429-2008-LLP-RO-KA3-KA3MP), with the main purpose of enhancing graduates' employability possibilities. For graduating students looking for a job it is perhaps harder than ever to meet success on the job market. They must use every tool they know to express themselves and to reflect their knowledge, competences and skills. The book aims to explain the main aspects of using digital storytelling as a method for employability, career development, reflection, assessment, consultancy, presentation and communication. Through digital storytelling, students begin to comprehend how all the elements of writing a narrative work together and how to manipulate them for the best effects in readers and viewers. Also, sharing and evaluating digital stories among peers is an excellent way to foster self-expression and tolerance and to create an engaged community of learners.

Research methodology. The following methods were used in this research: general scientific methods (descriptive, analysis, synthesis, comparison) and special (structural, hermeneutic, narrative, method of content analysis). We identified words related to the concept of the enemy and determined the context in which they are used by the authors of the collections Results. The formats of reflection of military reality in collections of military documentaries are investigated. It is emphasized that the authors-observers of events as professional communicators form a vision of events based on categories understandable to the audience – «own» and «others». Instead, the authors-participants go events have more creative space and pay more attention to their own emotional state and reflections. It is defined how the enemy is depicted and what place he occupies in the military reality represented by the authors. It is emphasized that the authors reflect the enemy in different ways. In particular, the authors-observers of the events tried to form a comprehensive vision of the events, and therefore paid much attention to the opposite side of the military conflict. Authors-participants of the events tend to show the enemy as a mass to be opposed. In such collections, the enemy is specified only in the presence of evidence confirming the presence of Russians or militants. Novelty. The research for the first time investigates the methods of representation of military activity in the collections of Ukrainian military documentaries. The article is devoted to the analysis of how the authors represent the enemy. Practical importance. The analysis of collections of military documentaries will allow to study the phenomenon of war and to trace the peculiarities of the authors’ representation of military reality.

Purpose/Background Direct laryngoscopy and endotracheal intubation after induction of anesthesia can cause a reflex sympathetic surge of catecholamines caused by airway stimulation. This may cause hypertension, tachycardia, and arrhythmias. This reflex can be detrimental in patients with poor cardiac reserve and can be poorly tolerated and lead to adverse events such as myocardial ischemia. Fentanyl, a potent opioid, with a rapid onset and short duration of action is given during induction to block the sympathetic response. With a rise in the opioid crisis and finding ways to change the practice in medicine to use less opioids, dexmedetomidine, an alpha 2 adrenergic agonist, can decrease the release of norepinephrine, has analgesic properties, and can lower the heart rate. Methods In this scoping review, studies published between 2009 and 2021 that compared fentanyl and dexmedetomidine during general anesthesia induction and endotracheal intubation of surgical patients over the age of 18 were included. Full text, peer-reviewed studies in English were included with no limit on country of study. The outcomes included post-operative reviews of decrease in pain medication usage and hemodynamic stability. Studies that were included focused on hemodynamic variables such as systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate, and use of opioids post-surgery. Result Of 2,114 results from our search, 10 articles were selected based on multiple eligibility criteria of age greater than 18, patients undergoing endotracheal intubation after induction of general anesthesia, and required either a dose of dexmedetomidine or fentanyl to be given prior to intubation. Dexmedetomidine was shown to effectively attenuate the sympathetic surge during intubation over fentanyl. Dexmedetomidine showed a greater reduction in heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure than fentanyl, causing better hemodynamic stability in patients undergoing elective surgery.Implications for Nursing Practice Findings during this scoping review indicate that dexmedetomidine is a safe and effective alternative to fentanyl during induction of general anesthesia and endotracheal intubation in attenuating the hemodynamic response. It is also a safe choice for opioid-free anesthesia.

Objective. To assess the comparative benefits and harms across three airway management approaches (bag valve mask [BVM], supraglottic airway [SGA], and endotracheal intubation [ETI]) by emergency medical services in the prehospital setting, and how the benefits and harms differ based on patient characteristics, techniques, and devices. Data sources. We searched electronic citation databases (Ovid® MEDLINE®, CINAHL®, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, and Scopus®) from 1990 to September 2020 and reference lists, and posted a Federal Register notice request for data. Review methods. Review methods followed Agency for Healthcare Research and Quality Evidence-based Practice Center Program methods guidance. Using pre-established criteria, studies were selected and dual reviewed, data were abstracted, and studies were evaluated for risk of bias. Meta-analyses using profile-likelihood random effects models were conducted when data were available from studies reporting on similar outcomes, with analyses stratified by study design, emergency type, and age. We qualitatively synthesized results when meta-analysis was not indicated. Strength of evidence (SOE) was assessed for primary outcomes (survival, neurological function, return of spontaneous circulation [ROSC], and successful advanced airway insertion [for SGA and ETI only]). Results. We included 99 studies (22 randomized controlled trials and 77 observational studies) involving 630,397 patients. Overall, we found few differences in primary outcomes when airway management approaches were compared. • For survival, there was moderate SOE for findings of no difference for BVM versus ETI in adult and mixed-age cardiac arrest patients. There was low SOE for no difference in these patients for BVM versus SGA and SGA versus ETI. There was low SOE for all three comparisons in pediatric cardiac arrest patients, and low SOE in adult trauma patients when BVM was compared with ETI. • For neurological function, there was moderate SOE for no difference for BVM compared with ETI in adults with cardiac arrest. There was low SOE for no difference in pediatric cardiac arrest for BVM versus ETI and SGA versus ETI. In adults with cardiac arrest, neurological function was better for BVM and ETI compared with SGA (both low SOE). • ROSC was applicable only in cardiac arrest. For adults, there was low SOE that ROSC was more frequent with SGA compared with ETI, and no difference for BVM versus SGA or BVM versus ETI. In pediatric patients there was low SOE of no difference for BVM versus ETI and SGA versus ETI. • For successful advanced airway insertion, low SOE supported better first-pass success with SGA in adult and pediatric cardiac arrest patients and adult patients in studies that mixed emergency types. Low SOE also supported no difference for first-pass success in adult medical patients. For overall success, there was moderate SOE of no difference for adults with cardiac arrest, medical, and mixed emergency types. • While harms were not always measured or reported, moderate SOE supported all available findings. There were no differences in harms for BVM versus SGA or ETI. When SGA was compared with ETI, there were no differences for aspiration, oral/airway trauma, and regurgitation; SGA was better for multiple insertion attempts; and ETI was better for inadequate ventilation. Conclusions. The most common findings, across emergency types and age groups, were of no differences in primary outcomes when prehospital airway management approaches were compared. As most of the included studies were observational, these findings may reflect study design and methodological limitations. Due to the dynamic nature of the prehospital environment, the results are susceptible to indication and survival biases as well as confounding; however, the current evidence does not favor more invasive airway approaches. No conclusion was supported by high SOE for any comparison and patient group. This supports the need for high-quality randomized controlled trials designed to account for the variability and dynamic nature of prehospital airway management to advance and inform clinical practice as well as emergency medical services education and policy, and to improve patient-centered outcomes.

Purpose The purpose of this study is to compare the incidence of post-operative nausea and vomiting (PONV) in opioid-utilizing and opioid-free general anesthesia. Background PONV is an extremely common, potentially dangerous side effect of general anesthesia. PONV is caused by a collection of anesthetic and surgical interventions. Current practice to prevent PONV is to use 1-2 antiemetics during surgery, identify high risk patients and utilize tracheal intubation over laryngeal airways when indicated. Current research suggests minimizing the use of volatile anesthetics and opioids can reduce the incidence of PONV, but this does not reflect current practice. Methods In this scoping review, the MeSH search terms used to collect data were “anesthesia”, “postoperative nausea and vomiting”, “morbidity”, “retrospective studies”, “anesthesia, general”, “analgesics, opioid”, “pain postoperative”, “pain management” and “anesthesia, intravenous”. The Discovery Search engine, AccessMedicine and UpToDate were the search engines used to research this data. Filters were applied to these searches to ensure all the literature was peer-reviewed, full-text and preferably from academic journals. Results Opioid free anesthesia was found to decrease PONV by 69%. PONV incidence was overwhelming decreased with opioid free anesthesia in every study that was reviewed. Implications The future direction of opioid-free anesthesia and PONV prevention are broad topics to discuss, due to the nature of anesthesia. Administration of TIVA, esmolol and ketamine, as well as the decision to withhold opioids, are solely up to the anesthesia provider’s discretion. Increasing research and education in the importance of opioid-free anesthesia to decrease the incidence of PONV will be necessary to ensure anesthesia providers choose this protocol in their practice.

The article investigates functional techniques of extralinguistic expression in multimedia texts; the effectiveness of figurative expressions as a reaction to modern events in Ukraine and their influence on the formation of public opinion is shown. Publications of journalists, broadcasts of media resonators, experts, public figures, politicians, readers are analyzed. The language of the media plays a key role in shaping the worldview of the young political elite in the first place. The essence of each statement is a focused thought that reacts to events in the world or in one’s own country. The most popular platform for mass information and social interaction is, first of all, network journalism, which is characterized by mobility and unlimited time and space. Authors have complete freedom to express their views in direct language, including their own word formation. Phonetic, lexical, phraseological and stylistic means of speech create expression of the text. A figurative word, a good aphorism or proverb, a paraphrased expression, etc. enhance the effectiveness of a multimedia text. This is especially important for headlines that simultaneously inform and influence the views of millions of readers. Given the wide range of issues raised by the Internet as a medium, research in this area is interdisciplinary. The science of information, combining language and social communication, is at the forefront of global interactions. The Internet is an effective source of knowledge and a forum for free thought. Nonlinear texts (hypertexts) – «branching texts or texts that perform actions on request», multimedia texts change the principles of information collection, storage and dissemination, involving billions of readers in the discussion of global issues. Mastering the word is not an easy task if the author of the publication is not well-read, is not deep in the topic, does not know the psychology of the audience for which he writes. Therefore, the study of media broadcasting is an important component of the professional training of future journalists. The functions of the language of the media require the authors to make the right statements and convincing arguments in the text. Journalism education is not only knowledge of imperative and dispositive norms, but also apodictic ones. In practice, this means that there are rules in media creativity that are based on logical necessity. Apodicticity is the first sign of impressive language on the platform of print or electronic media. Social expression is a combination of creative abilities and linguistic competencies that a journalist realizes in his activity. Creative self-expression is realized in a set of many important factors in the media: the choice of topic, convincing arguments, logical presentation of ideas and deep philological education. Linguistic art, in contrast to painting, music, sculpture, accumulates all visual, auditory, tactile and empathic sensations in a universal sign – the word. The choice of the word for the reproduction of sensory and semantic meanings, its competent use in the appropriate context distinguishes the journalist-intellectual from other participants in forums, round tables, analytical or entertainment programs. Expressive speech in the media is a product of the intellect (ability to think) of all those who write on socio-political or economic topics. In the same plane with him – intelligence (awareness, prudence), the first sign of which (according to Ivan Ogienko) is a good knowledge of the language. Intellectual language is an important means of organizing a journalistic text. It, on the one hand, logically conveys the author’s thoughts, and on the other – encourages the reader to reflect and comprehend what is read. The richness of language is accumulated through continuous self-education and interesting communication. Studies of social expression as an important factor influencing the formation of public consciousness should open up new facets of rational and emotional media broadcasting; to trace physical and psychological reactions to communicative mimicry in the media. Speech mimicry as one of the methods of disguise is increasingly becoming a dangerous factor in manipulating the media. Mimicry is an unprincipled adaptation to the surrounding social conditions; one of the most famous examples of an animal characterized by mimicry (change of protective color and shape) is a chameleon. In a figurative sense, chameleons are called adaptive journalists. Observations show that mimicry in politics is to some extent a kind of game that, like every game, is always conditional and artificial.

The National Wildlife Research Center (NWRC) is to apply scientific expertise to resolve human-wildlife conflicts while maintaining the quality of the environment shared with wildlife. As the research arm of the USDA Animal and Plant Health Inspection Service's (APHIS) Wildlife Services (WS) program, NWRC develops methods and information to address human-wildlife conflicts related to: (1) agriculture (crops, livestock, aquaculture, and timber); (2) human health and safely (wildlife disease, aviation); (3) property damage; (4) invasive species, and (5) threatened and endangered species. NWRC's research programs and priorities are based on nationwide research needs assessments, Congressional directives, WS program needs, and stakeholder input. NWRC research is organized under three research programs that reflect APHIS' commitment to "protecting agricultural and natural resources from agricultural animal and plant health threats, zoonotic diseases, invasive species, and wildlife conflicts and diseases".
