Introduction: The effect of a bare-metal stent on the hemodynamics in the main branch of a coronary artery bifurcation with a particular type of stenosis was numerically investigated by the computational fluid dynamics (CFD). Methods: Three-dimensional idealized geometry of bifurcation was constructed in Catia modelling commercial software package. The Newtonian blood flow was assumed to be incompressible and laminar. CFD was utilized to calculate the shear stress and blood pressure distributions on the wall of main branch. In order to do the numerical simulations, a commercial software package named as COMSOL Multiphysics 5.3 was employed. Two types of stent, namely, one-part stent and two-part stent were applied to prevent the build-up and progression of the atherosclerotic plaques in the main branch. Results: A particular type of stenosis in the main branch was considered in this research. It occurred before and after the side branch. Moreover, it was found that the main branch with an inserted one-part stent had the smallest region with the wall shear stress (WSS) below 0.5 Pa which was the minimum WSS in the main branch without the stenosis. Conclusion: The use of a one-part stent in the main branch of a coronary artery bifurcation for the aforementioned type of stenosis is recommended.

Full textAbstract:
Little is known about the first stars, but hints on this stellar population can be derived from the peculiar chemical composition of the most metal-poor objects in the Milky Way and in resolved stellar populations of nearby galaxies. In this paper, we review the evolution and nucleosynthesis of metal-poor and extremely metal-poor (EMP) stars with low and intermediate masses. In particular, new models of 6 M⊙ with three different levels of metallicity, namely Z=10−4, 10−6 and 10−10, are presented. In addition, we illustrate the results obtained for a 2 M⊙, Z=10−5 model. All these models have been computed by means of the latest version of the FuNS code. We adopted a fully coupled scheme of solutions for the complete set of differential equations describing the evolution of the physical structure and the chemical abundances, as modified by nuclear processes and convective mixing. The scarcity of CNO in the material from which these stars formed significantly affects their evolution, their final fate and their contribution to the chemical pollution of the ISM in primordial galaxies. We show the potential of these models for the interpretation of the composition of EMP stars, with particular emphasis on CEMP stars.

The third dredge-up phenomenon in asymptotic giant branch stars, responsible for the formation of C stars, is discussed based on detailed evolutionary model calculations. The structural readjustment of the star as dredge-up proceeds is analyzed, and its consequences on dredge-up predictions discussed. The question of how to obtain dredge-up in asymptotic giant branch models is also addressed. It is stressed, in particular, that the modeling of dredge-up requires some sort of extra-mixing to be applied below the envelope if the local Schwarzschild criterion is used to delimit convective zones.

AbstractWe show that the current data of the HB branch of 47 Tuc show a particular feature that cannot be explained if a single population with an unique mechanism of mass loss is considered. We find that a spread in helium abundance among the stars is necessary, of ~0.02. We indicate that the same variation in helium is present among the sub giant branch stars and suggest that is responsible of the spread in luminosity of the bright sub giant branch, while only a small part of the second generation is characterized by C+N+O increase and gives the faint sub giant branch.

AbstractWe present new results from spectro-photometric models for elliptical galaxies in which detailed descriptions of the star formation history and chemical enrichment are taken into account. In particular, we focus on the important role played stars of different chemical composition evolving along the red giant branch (RGB), horizontal branch (HB), asymptotic giant branch (AGB), and finally planetary nebula (PN) stages in relation to the sources of UV flux in elliptical galaxies. A few important applications of these new galaxy models are briefly outlined.

Full textAbstract:
Ghost-free bimetric theory can describe gravity in the presence of an extra spin-2 field. In this paper, we study certain aspects of dynamics in this theory: (i) It is shown that if either of the metrics is an Einstein solution, then the other is always forced to be Einstein, too. For a class of bimetric models, this constraint is stronger and as soon as one metric is Einstein, the other metric is forced to be proportional to it. As a consequence, the models in this class avoid a branch of pathological solutions that exhibit determinant singularities or nonlinear ghosts. These constraints persists in a generalized form when sources are included, but are destroyed in the massive gravity limit of the theory. (ii) For another class of bimetric models, we show the existence of solutions that do not admit a massive gravity limit. A bimetric model that could exhibit a nonlinear version of "partially massless" symmetry belongs to both these classes. It is argued that if such a model exist, its symmetry will not survive in the massive gravity limit.

Full textAbstract:
The present study charts the evolution of the general chapter, an organ of government that has long historical roots in the Church, one that, as this is the case for IBVM, has proved capable of adjusting and adapting to the demands of life and mission in the modern world. The contemporary understanding of the nature and authority of the general chapter has been influenced by Vatican II's renewed vision of authority as service. In this vision, as is evident from CIC's expression of government in institutes of consecrated life, authority, even within an hierarchical model, is exercised participatively, collaboratively and where possible collegially. However, the general chapter is more than a juridic structure of governance. It is primarily a faith experience whose main task is the union in charity of the members. As a result, prayer and discernment must characterize its participative, collaborative processes.
The fusion of IBVM North America with IBVM Irish Branch in 2003 brought together two Institutes whose charism derived from the same source. Despite their common origins, however, the two Institutes understood authority, its expression in proper law and its exercise in key areas such as the general chapter in apparently different ways. This difference was epitomized in 1986 when one Institute adopted the Ignatian Constitutions while the other rejected them because their hierarchical expression of authority was believed to be incompatible with the way women function in the modern world. The experience of IBVM in North America since Vatican II would seem to suggest that participative, collaborative structures (which are described as a more "feminine" approach to government), functioning within an hierarchical system can meet the need for meaningful involvement of members in government. However, this more "democratic" expression of government can open the members to individualism and majoritarianism. The changes made by the Irish Branch in the exercise of government since 1986 provide hope that an inclusive, participative model of government can be accommodated in the new IBVM Loreto Branch.
Because consecrated life has an inalienable ecclesial dimension, understanding authority and power and their exercise in institutes of consecrated life has relevance for understanding authority and its exercise in other organs of authority at all levels in the Church.

Full textAbstract:
L’optimisation de la planification de la maintenance des équipements de production d’électricité est une question importante pour éviter des temps d’arrêt inutiles et des coûts opérationnels excessifs. Dans cette thèse, nous présentons une classification multidimensionnelle des études de Recherche Opérationnelle portant sur ce sujet. Le secteur des énergies renouvelables étant en pleine expansion, nous présentons et discutons ensuite d’un problème de maintenance de parcs éoliens terrestres. Le problème est traité sur un horizon à court terme et l’objectif est de construire un planning de maintenance qui maximise le revenu lié à production d’électricité des éoliennes tout en prenant en compte des prévisions de vent et en gérant l’affectation de techniciens. Nous présentons plusieurs modélisations du problème basées sur la programmation linéaire. Nous décrivons aussi une recherche à grands voisinages basée sur la programmation par contraintes.Cette méthode heuristique donne des résultats probants.Nous résolvons ensuite le problème avec une approche exacte basée sur une décomposition du problème. Dans cette méthode, nous construisons successivement des plannings de maintenance optimisés et rejetons, à l’aide de coupes spécifiques, ceux pour lesquels la disponibilité des techniciens est insuffisante. Les résultats suggèrent que cette méthode est la mieux adaptée pour ce problème. Enfin, pour prendre en compte l’incertitude inhérente à la prévision de vitesses de vent, nous proposons une approche robuste dans laquelle nous prenons des décisions garantissant la réalisabilité du planning de maintenance et le meilleur revenu pour les pires scénarios de ventEfficiently scheduling maintenance operations of generating units is key to prevent unnecessary downtime and excessive operational costs. In this work, we first present a multidimensional classification of the body of work dealing with the optimization of the maintenance scheduling in the operations research literature. Motivated by the recent emergence of the renewable energy sector as an Environmental priority to produce low-carbon power electricity, we introduce and discuss a challenging Maintenance scheduling problem rising in the onshore wind industry. Addressing the problem on a short-term horizon, the objective is to find a maintenance plan that maximizes the revenue generated by the electricity production of the turbines while taking into account wind predictions, multiple task execution modes, and technician-to-task assignment constraints. We start by presenting several integer linear Programming formulations of the problem. We then describe a constraint programming-based large neighborhood search which proves to be an efficient heuristic solution method. We then design an exact branch-and-check approach based on a decomposition of the problem. In this method, we successively build maintenance plans while discarding – using problem-specific cuts – those that cannot be performed by the technicians. The results suggest that this method is the best suited to the problem. To tackle the Inherent uncertainty on the wind speed, we also propose a robust approach in which we aim to take risk-averse decisions regarding the revenue associated with the maintenance plan and its feasibility

Full textAbstract:
Com este estudo pretendemos analisar Camilo Castelo Branco em duas perspectivas distintas: leituras e leitores do autor.
Tido como um dos maiores escritores portugueses do século XIX, Camilo Castelo Branco foi influenciado, não só por autores europeus, como também pelos clássicos, com quem travara conhecimento desde muito cedo.
De qualquer modo, outras leituras faremos da sua obra literária: quais dos seus percursos mais influenciaram os leitores; quem foram e são os seus leitores; por que razão marcou tão fortemente a cultura portuguesa; quais as marcas de identidade presentes na sua obra. Estas são algumas das linhas que norteiam a investigação.
Camilo revelava uma linguagem invulgar, onde a vertente clássica, a par da sentimental e romântica, se explicam pela leitura dos autores clássicos, junto do padre António de Azevedo, e a linguagem popular se deve ao contacto directo tido com o povo no Minho e em Trás-os-Montes. Em Camilo, encontrámos uma oratória vocabular extraordinária, graças ao uso de léxico extremamente rico e colorido, assim como de uma linguagem vernácula exemplar.
No que concerne aos leitores de Camilo, e após uma análise, ainda que breve, da sociedade portuguesa, a nossa escolha recaiu em Agustina Bessa-Luís já que a sua obra tem espelhado Camilo Castelo Branco e sabido trazer à actualidade as paixões e os infortúnios amorosos provocados por desigualdades sociais, ódios de família, rejeição e abandono, intriga e ciúme, ingenuidade das meninas românticas, boçalidade das pessoas do povo, e todo um mundo de personagens visto por Camilo e revisitado por Agustina nas obras Fanny Owen e Camilo: Génio e Figura.

Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgicoEstudaremos uma tÃcnica de suavizaÃÃo de uma singularidade nua em um conifold chamada Brane Resolution Por um lado a singularidade aparece como uma soluÃÃo de brana de supergravidade contendo apenas termos do setor de Neveu-Schwarz Por outro lado podemos ver a singularidade do conifold como oriunda de um ponto fixo do grupo de simetria discreto responsÃvel pela geraÃÃo do conifold O conifold tem bastante importÃncia no processo de compactificaÃÃo em teorias de cordas em particular nas chamadas transiÃÃes cÃnicas De fato existem diferentes tipos de espaÃos deCalabi-Yau que podem ser variedades internas Apesar de tais espaÃos terem caracterÃsticas to- polÃgicas distintas pode-se transformar um espaÃo no outro atravÃs das transiÃÃes cÃnicas Isso se faz atravÃs da geraÃÃo de singularidades no espaÃo de Calabi-Yau que surpreendentemente nÃo gera problemas quÃnticos. A tÃcnica consiste em acrescentar um termo topolÃgico do setor de Ramond-Ramond à aÃÃo A inclusÃo de um termo de Chern-Simons responsÃvel pela interaÃÃo entre os campos do setor de Ramond-Ramond (Cn ), gera um fluxo dos campos H3 = dB2 e F3 = dC2 sobre a singularidade do conifold. A partir da equaÃÃo de movimento do campo pode-se, dado uma escolha adequada para a configuraÃÃo da mÃtrica e dos campos, encontrar os fatores de warp que sÃo responsÃveis pela retirada da singularidade O mÃtodo tambÃm pode ser entendido topologicamente como a incisÃo de uma esfera no lugar da vizinhanÃa do nodo do cone O estudo do comportamento de campos sobre o conifold à feito no intuito de extender a correspondÃncia AdS-CFT originalmente a correspondÃncia foi proposta para o espaÃo AdS5 ÃS 5 mas logo surgiram extensÃes utilizando outras variedades como M4 à C6 PrÃximo a singula- ridade o espaÃo pode ser escrito como AdS5 à X 5 onde X 5 à o espaÃo base do conifold Geralmente toma-se o espaÃo base como um espaÃo homogÃneo de Einstein Ricci-plana onde X 5 = SU (3)/SU (2) à SU (2). Contudo, para manter a invariÃncia conforme da teoria de campos dual à necessÃrio suavizar o conifold atravÃs de incisÃes do tipo Eguchi-Hanson que podem ser de dois tipos: por uma 3-esfera S 3 à chamada deformation ou por uma 2-esfera S 2 à chamada resolution Recentemente foram propostas resoluÃÃes do conifold em um cenÃrio de teoria heterÃtica dotada de torÃÃo Tal efeito à relevante em teorias onde soluÃÃes do tipo buraco negro existem na variedade interna como as black branes e spinning branes esta Ãltima leva em conta o momento angular do buraco negro - spin - e à uma soluÃÃo do tipo Kerr A partir da transgressÃo da identidade de Bianchi para a 3-forma intensidade de campo de Kalb-Ramond oriundo de um termo de Gauss-Bonnet e de instanton podemos introduzir uma torÃÃo e com isso um novo termo na conexÃo nÃo dependente da mÃtrica. Estudaremos os efeitos de tais termos sobre a suavizaÃÃo de um conifold comparando com o caso sem torÃÃo AlÃm disso buscamos estudar o efeito que um outro termo topolÃgico tem sobre a resoluÃÃo de branas o termo BF Tal termo surgiu como uma extensÃo do termo de Chern-Simons para quatro dimensÃes tendo como funÃÃo gerar massa topologicamente para campos de calibre Nesse trabalho iremos modificar a aÃÃo da teoria heterÃtica de modo a obtermos o termo BF como um dos termos de anomalia e logo responsÃvel pelo fluxo que retira a singularidade Encontramos para um ansatz bastante conhecido uma configuraÃÃo onde o fluxo gerado pelo termo BF à o responsÃvel pela desingularizaÃÃo do espaÃo
We will study a technique for smoothing a naked singularity in a conifold called Brane Resolution On the one hand the singularity appears as a brane solution of supergravity containing only terms of sector Neveu-Schwarz On the other hand we can see the singularity of the conifold as coming from a fixed point of the discrete symmetry group responsible for generating the conifold The conifold is of most importance in the process of compactification in string theories in particular in so-called conical transitions In fact there are different kinds Calabi-Yau varieties that can be built Despite such spaces have distint topological characteristics it can become a space on the other transitions through conical transitions This is done through the generation of singularities in Calabi-Yau that surprisingly does not generate quantum problems. The technique consists of adding a topological term sector Ramond-Ramond action to the inclusion of a Chern-Simons term responsible for interaction between the fields of the Ramond-Ramond sector (Cn), generates a flow field and H3 = DB2 F3 = DC2 on the singularity of the conifold. From the equation of motion of the field and an appropriate choice for the configuration of the metric and fields find the warp factors that are responsible for the removal of the singularity method can also be understood topologically as the incision of a sphere in the vicinity of the place node of the cone The behavior of fields on the conifold is done in order to extend the correspondence AdS-CFT correspondence was originally proposed for the space AdS5 Ã S 5 but soon emerged as extensions using other varieties M4 Ã C6 Near the natural perity space can be written as AdS5 5 Ã X 5 where X is the base of the conifold space usually takes up the space base as a homogeneous space of Ricci-flat Einstein where X = 5 SU (3) / SU (2) Ã SU (2). However, to maintain conformal invariance of the theory of dual fields is necessary to soften the conifold through incisions of the Eguchi-Hanson type that can be of two types: a 3-sphere S 3 is called deformation or by a 2-sphere S 2 is called resolution Recently it has been proposed resolutions conifold in a scenario of heterotic theory endowed with torsion Such an effect is relevant in theories where the black hole type solutions exist in the internal variety as the branes and spinning black branes latter takes into account the black hole's angular momentum - spin - and it is a solution of Kerr From the transgression of the Bianchi identity for the 3-form field strength of the Kalb-Ramond term derived from a Gauss-Bonnet and instanton can introduce a twist and hence a new term not dependent on the connection meter. We will study the effects of such terms on conifold a smoothing compared with the case without torsion Furthermore we study the effect that another term has topological branes on the resolution of the term BF This term originated as an extension of the Chern-Simons term to four dimensions with topologically generate mass function as gauge fields for this work, we modify the action of the heterotic theory in order to obtain the term BF as one of the terms fault and then responsible for the flow that removes the singularity found for an ansatz well known a configuration where the flow generated by the BF term is responsible for resolution

O ozônio (O3) e material particulado fino (PM2,5) são os poluentes com maior impacto na saúde pública. Cerca de 0,7 milhões de mortes por doenças respiratórias e 3,5 milhões de mortes por doenças cardiopulmonares ocorrem anualmente no mundo devido à exposição ao O3 e ao PM2,5, respectivamente, oriundos de atividades antropogênicas. Objetivo: Avaliar o risco da exposição ao O3 e ao PM2,5 em escolares a partir da estimativa da dose potencial de ingresso no município de Rio Branco-Acre, em 2009. Método: A metodologia de Avaliação de Risco foi aplicada para avaliar o risco da exposição ao O3 e ao PM2,5 proveniente da queima de biomassa, em escolares de 6 a 14 anos de idade, residentes em Rio Branco, nos meses de agosto a outubro de 2009, que corresponde ao período de seca. A estimativa da dose potencial de ingresso para os poluentes O3 e PM2,5 foi realizada através da simulação de Monte Carlo segundo idade, sexo, asma e índice de massa corporal. O risco toxicológico foi estimado por meio da razão da dose potencial de ingresso e dose de referência para os dois poluentes em estudo. Resultados: As maiores concentrações de O3 e PM2,5 em 2009 atingiram concentrações de 119,4 g/m3 e 51,1 g/m3, respectivamente. Os escolares incorporaram doses potenciais médias para a exposição ao O3 de 2,83g/kg.dia (IC95%: 2,72 – 2,94) e para o PM2,5 de 0,93g/kg.dia (IC 95%: 0,86 – 0,99). Para a exposição ao O3 o risco toxicológico foi maior que 1 para todas as crianças (QR=2,75; IC 95%: 2,64 – 2,86). Conclusão: Escolares residentes em Rio Branco, município localizado na Amazônia brasileira, foram expostos a doses elevadas de O3 no período de seca na região, representando risco toxicológico. Para a exposição ao PM2,5 não foi verificado risco toxicológico.
Ozone (O3) and fine particulate matter (PM2,5) are the pollutants with the greatest impact on public health. About 0.7 million deaths from respiratory diseases and 3.5 million deaths from cardiopulmonary diseases occur worldwide each year due to exposure to O3 and PM2,5, respectively, arising from anthropogenic activities.Objective: Risk assessment of exposure to O3 and PM2,5 in schoolchildren aged 6 to 14 years, from the estimate of potential dose ingress in Rio Branco, Acre, 2009. Method: The Risk Assessment methodology was applied to assess the risk of exposure to O3 and PM2,5, from biomass burning in children living in Rio Branco, in the months from August to October 2009, which corresponds to the period of drought. The estimate of ingress potential dose for pollutants O3 and PM2,5 was performed by Monte Carlo simulation according to age, sex, asthma and body mass index. The toxicologic risk was estimated by ratio between of the potential dose and reference dose for each pollutant studied. Results: The highest concentrations of O3 and PM2,5 in 2009 reached 119.4 g/m3 and 51.1 g/m3, respectively. The schoolchildren have incorporated doses averages potential for exposure to O3 of 2.83 g/kg.dia (CI 95%: 2.72 - 2.94) and for PM2,5 of 0.93 g/kg.dia (CI 95%: 0.86 - 0.99). To exposure to O3 toxicologic risk was greater than 1 for all children (QR = 2.75; CI 95%: 2.64 - 2.86). Conclusion: Children living in Rio Branco, a city located in the Brazilian Amazon were exposed to high doses of O3 pollution in the dry period in the region, presenting toxicological risk to the pollutant. To exposure to PM2, 5 schoolchildren showed no toxicological risk.

A linha principal dessa tese relaciona-se com teorias supersimÃtricas. Junta-se à essa linha principal uma discussÃo sobre propagadores de campos de Kalb-Ramond em branas. Na realidade os campos anti-simÃtricos sÃo outro fio condutor deste trabalho, aparecendo em quase todos os tÃpicos. Inicialmente, em branas do tipo delta de Dirac, tÃpicas dos modelos de Dvali de Randall-Sundrum, mostramos que a relaÃÃo que ocorre entre os propagadores de campos vetoriais em D=4 e D=5 dimensÃes espaÃo-temporais, continua vÃlida quando tratamos campos tensoriais anti-simÃtricos. Tal resultado subsidia especulaÃÃes de que campos tensoriais podem ser localizados na brana. No que tange a teorias com supersimetria, nossas investigaÃÃes se dividem em trÃs direÃÃes, a saber: 1) modelos topolÃgicos em D=5, no contexto da chamada pseudo-supersimetria, 2) construÃÃo de uma descriÃÃo plena do superespaÃo em D=5, inÃdita na literatura, a qual denominamos de superespaÃo intrÃnseco, para diferenciar da proposta de pseudo-supersimetria em D=5, 3) descriÃÃo do efeito Aharanov-Casher em uma teoria supersimÃtrica em D=4 com termo de quebra de Lorentz. Quanto a modelos topolÃgicos, realizamos a extensÃo pseudosupersimÃtrica em D=5, de um termo com estrutura anÃloga ao termo de Chern-Simons, mas envolvendo apenas o campo tensorial de gauge de Kalb-Ramond . Obtivemos a expansÃo completa dos supercampos e demonstramos em detalhes o nÃmero de graus de liberdade do tensor anti-simÃtrico de rank-2 em D=5. Uma vez que construÃmos a expansÃo completa do supercampo de Kalb-Ramond, determinamos o parceiro fermiÃnico do termo topolÃgico 5-dimensional. Por outro lado, insatisfeitos com o formalismo existente na literatura para tratar sistemas com supersimetria em (4+1) dimensÃes, especialmente tendo em vista aplicaÃÃes em teorias de branas, construÃmos o formalismo de superespaÃo N=1 - D=5. Encontramos os geradores, e, conseqÃentemente, as derivadas covariantes de supersimetria e mostramos que existe uma dependÃncia explÃcita da quinta coordenada. Este à um resultado que permite propagaÃÃo na dimensÃo extra, a qual nÃo à descrita no formalismo de pseudosupersimetria uma vez que sÃo usadas as mesmas derivadas covariantes de supersimetria de quatro dimensÃes. Escrevemos o Modelo de Wess-Zumino em cinco dimensÃes usando o formalismo de supersimetria intrÃnseca, assim como um supercampo vetorial, o que permitiu a construÃÃo de uma teoria manifestamente supersimÃtrica em D=5 com invariÃncia de gauge. Por fim, no contexto de uma teoria supersimÃtrica em D=4, utilizamos um ansatz para quebrar a simetria de Lorentz, simplesmente impondo que determinado campo do modelo à constante, ao mesmo tempo em que a supersimetria à preservada. Adicionamos o termo de Fayet-Illiopoulos, que nos fornece um potencial e a partir da presenÃa desse potencial escrevemos uma nova lagrangiana que permite obter o efeito Aharonov-Casher em uma teoria supersimÃtrica com termo de quebra de Lorentz. Vale a pena mencionar ainda, quatro apÃndices, a saber: convenÃÃo e revisÃo de espinores; formas diferenciais para supercampos; a prova detalhada da existÃncia de trÃs graus de liberdade on-shell em D=5 para o campo de Kalb-Ramond; e Ãlgebra de deSitter nas representaÃÃes vetorial e espinorial SO(1,4).

Full textAbstract:
The book analyses the history of the Jesuat congregation, highlighting the elements of connection and comparison with the social contexts, then describing the origin and the most ancient events of the female branch of the congregation, and the memory of the meeting between the "founder" of the Jesuats and the "foundress" of the Gesuate. The iconographic memory of the initiator of the congregation, Giovani Colombini, the collection of the lauds of the Jesuat Bianco da Siena, and the fortune of the 15th-century Life of Giovanni Colombini, written by Feo Belcari, are also investigated. Then the research reconstructs the constellation of groups, religious experiments and bearers of ideas and devotions that were linked to the Jesuats and, in particular, to the convents of Milan, Siena, Lucca, Venice and Rome and the sanctuaries managed by the congregation. The congregational sociability is analysed along its lines: the practice of work as pharmacists and the cultivation of spiritual friendships with prominent people such as the Countess of Guastalla, Lodovica Torelli. Finally, the erudite use of Colombini's Epistolario as a language text is studied. The volume closes with a documentary appendix on the Jesuat convent of Chiusi.

Full textAbstract:
In the period following the Second World War Giulio Preti was one of the leading exponents of Italian philosophy. A master of open critical thought, cultivated in the light of a rationalism that dialogued with, and integrated into his own philosophical model, many of the currents and stances of the global research scenario. Phenomenology, Marxism, pragmatism, neopositivism, transcendentalism and structuralism: in Preti all of these found an organic and original synthesis. Further, his particular brand of rationalist-critical thought touched on many aspects of philosophical knowledge: theoretical philosophy, the philosophy of science, that of language and that of art, from ethics to politics and even taking in the history of philosophy, offering authoritative contributions in every sphere. One hundred years after his birth, the University of Florence and the heir to the Faculty in which he lectured at length, the Faculty of Education, has decided to honour his memory with this anthology of studies, penned by former pupils and others and also by younger scholars, to once again focus the wealth of this thought and its, in many respects, current relevance. Even now, this particular brand of open, critical rationalism can offer a benchmark for addressing the new issues for philosophical reflection thrown up by modern society and culture.

Full textAbstract:
States claim sovereignty, that is, to be the ultimate source of political authority in their realm. The classical conception of sovereignty defended by early modern thinkers such as Hobbes and Rousseau would give the sovereign extraordinary powers, the authority to rule on just about any matter concerning its subjects and territory. Few today defend this classical conception of sovereignty as unconstrained authority; most everyone thinks that the powers of the state are constrained and limited. Constrained states can still be very powerful, and today many argue that the power of the executive branch of government, in particular, ought to be less constrained than it is thought to be. This chapter argues that the concept of the sovereignty of the state, whether understood in a classical way or as limited, gives little support to those who argue that the executive branch ought to be relatively unconstrained in the realm of security and foreign affairs. The doctrine of the sovereignty of the state does not single out any branch of government for distinctive powers. While there may be reasons intrinsic to sovereignty to attribute greater powers to states, these reasons don’t privilege the executive branch of government. Our executive branches are not sovereigns.

The Australian and Canadian branches of OUP were among the first founded and their histories in the later twentieth century have similar trajectories. Both engaged in significant trade publishing, unlike other branches, and both developed successful local educational and reference lists. The New Zealand branch was a more precarious investment and eventually merged into the Australian branch. The Canadian and Australian branches both responded to powerful nationalist movements in education and publishing by embracing local authors and developing reference titles and textbooks. The chapter considers these developments and compares the publishing lists, leadership, and growth of the Australian and Canadian branches. The chapter carefully examines and compares the relationship between these branches and Oxford, particularly noting how the branches and the Press perceived and reacted to changes in financial position, sales figures of local titles and UK imports, and the autonomy of branch managers.

Traditionally OUP relied on travellers to promote and sell its books in the UK and branch staff to do so overseas; these activities were managed from the Sales Department at Ely House. Feedback from the branches and UK travellers on customer preferences did not reliably reach editors in Oxford and London. Following the reorganization of the Press in the 1970s, publishing divisions took control of marketing their own books and a greater priority was given to market preferences in decisions about design, format, pricing, timing of publication, and projected sales. The chapter chronicles the changes in marketing policy and sales techniques, offering examples of the impact of market analysis, customer feedback, and promotional campaigns on particular titles. The chapter also considers the way the Press reacted to changes in the retail book sales with the growth of chain stores, book clubs, and the online marketplace.

Buddhist international organizations are a dynamic phenomenon of contemporary Buddhism. The proliferation of these organizations is a significant manifestation of global and transnational forms of Buddhism. Common characteristics of international Buddhist organizations include charismatic leadership, a large lay Buddhist population, the establishment of local branch centers, and a focus on a particular form of Buddhist practice such as a meditation method or a form of social engagement. The author’s criteria for labeling international Buddhist organizations as such include a membership of diverse nationalities, multiple branch centers outside the country of its origin, and therefore a commitment to both national and international concerns. The chapter investigates the most relevant organizations structured by region and social issue. It includes examples of Buddhist international organizations throughout Asia, with a focus on common regional features. Precedents for Buddhist international organizations within the pre-modern and modern period are also included.

AbstractMilitary sociology, or more precisely, the sociology of military organizations, studies social facts about military institutions, their functional and structural components, and their relations with the societies that constitute their environments. Three periods can be roughly distinguished in the historical development of military sociology: the origins of the discipline, the Cold War period, and the current one. Like other subfields of sociology, the themes discussed in military sociology reflect the evolution of society at large. This particular branch of sociology bridges individual behaviors with broader social structures, in this case, military organizations.

It is expected that a doctor should act in a particular way and follow certain rules. Medical ethics are professional standards for physicians. Bioethics is a branch of medical ethics and deals with complex issues like euthanasia, transplant medicine, genetic medicine, assisted reproduction therapy, human cloning, and medical genomics. Medical ethics and bioethics concepts are guides for physicians and to ensure patient safety.

AbstractLocation normalization plans that are currently being established across the country encourage a loose approach to land utilization guidance by establishing the areas where urban function guidance and residential guidance apply. We will consider some hints as to how to proceed with urban downsizing by looking back at how urban areas expanded during the period of population growth. It is important that the characteristics and roles of each transport system are reorganized and that they are skillfully incorporated into cities. In particular, the formation of transfer points between main line transport systems and branch line transport systems is a key to the formation of compact cities.

Abstract From travel disruptions to natural disasters, extreme events have long captured the public’s imagination and attention. Due to their rarity and often associated calamity, they make waves in the news (Fig. 3.1) and stir discussion in the public realm: is it a freak event? Events of this sort may be shrouded in mystery for the general public, but a particular branch of probability theory, notably Extreme Value Theory (EVT), offers insight to their inherent scarcity and stark magnitude. EVT is a wonderfully rich and versatile theory which has already been adopted by a wide variety of disciplines in a plentiful way. From its humble beginnings in reliability engineering and hydrology, it has now expanded much further; it can be used to model the occurrences of records (say for example in athletic events) or quantify the probability of floods with magnitude greater than what has been observed in the past, i.e it allows us extrapolate beyond the range of available data!

AbstractAny discussion about the history of surgery inevitably begins with an invariable reference to Suśruta and his contributions to facial surgery, in particular. While the contributions of the sixth-century sage surgeon may somewhat be nebulous in a foggy poorly documented history, they are inevitably (and arguably) numerous but need not be elaborated here in any manner. What is lesser known and not often spoken about is that Suśruta considered surgery the first and foremost branch of medicine and stated, “Surgery has the superior advantage of producing instantaneous effects by means of surgical instruments and appliances. Hence, it is the highest in value of all the medical tantras. It is eternal and a source of infinite piety, imports fame and opens the gates of Heaven to its votaries. It prolongs the duration of human existence on earth and helps men in successfully fulfilling their missions and earning a decent competence in life.”

Full textAbstract:
AbstractThe most scalable approaches to certifying neural network robustness depend on computing sound linear lower and upper bounds for the network’s activation functions. Current approaches are limited in that the linear bounds must be handcrafted by an expert, and can be sub-optimal, especially when the network’s architecture composes operations using, for example, multiplication such as in LSTMs and the recently popular Swish activation. The dependence on an expert prevents the application of robustness certification to developments in the state-of-the-art of activation functions, and furthermore the lack of tightness guarantees may give a false sense of insecurity about a particular model. To the best of our knowledge, we are the first to consider the problem of automatically synthesizing tight linear bounds for arbitrary n-dimensional activation functions. We propose the first fully automated method that achieves tight linear bounds while only leveraging the mathematical definition of the activation function itself. Our method leverages an efficient heuristic technique to synthesize bounds that are tight and usually sound, and then verifies the soundness (and adjusts the bounds if necessary) using the highly optimized branch-and-bound SMT solver, dReal. Even though our method depends on an SMT solver, we show that the runtime is reasonable in practice, and, compared with state of the art, our method often achieves 2-5X tighter final output bounds and more than quadruple certified robustness.

“The Personal Origins of Collective Identity” presents life stories of individual movement participants, demonstrating that the collective identity and ideals of the Han Clothing Movement are cultural products of and responses to personal desires emergent within the challenges of reality. This chapter presents four detailed case studies of participants’ disenchanting everyday experiences in cities across China, alongside their re-creations within the movement overcoming their distance from the “great Han.” Analyses of these process highlight how personal aspirations and dilemmas are expressed and imaginarily resolved through individuals’ reinvention via movement fantasies of a coherent, glorious, and eternal majority identity. “Personal Origins” concludes with the discussion of a particularly self-mythologizing branch of the movement that is broadly derided by other branches, arguing that this derision is precisely a product of this particular branch’s rendering the personal desires inherent within the movement too explicitly.

It shows that the executive plays a pivotal role in the British constitution today, and that there are real concerns about whether it enjoys too much power—and about whether that power is subject to adequate oversight and control.

Full textAbstract:
Side branches are small diameter pipes attached to a main pipeline. If a high noise level is present in the pipeline then the side branch may suffer from damaging vibration or fatigue. The mechanics of the vibration involve an acoustic resonance of the fluid within the side branch which is coupled to a structural resonance. The particular conditions investigated in this paper are where the acoustic and structural natural frequencies coincide. It is shown that the resonant vibration amplitude is controlled by the following factors: (i) the degree of correlation of the acoustic wavelength with the distances between bends in the side branch, (ii) the structural and acoustic damping and (iii) the ratio of the structural mass to the mass of the internal fluid. Simple equations are presented for conditions that will result in coupling and for the maximum amplitude of the coupled vibration.

Full textAbstract:
Previous studies demonstrate that the presence of liquid strongly influences the pressure pulsation amplitudes of flow induced pulsations. In particular, in case of annular flow (thin liquid film on the walls) the pulsations can be eliminated. The present study aims at evaluating the contribution of the liquid film to the pulsation reduction. Experiments have been performed in a tandem configuration with two side branches upward oriented. The side branches have the same diameter as the main pipe. A first set of experiments has been conducted with the injection point located far upstream the upstream side branch. To isolate the sole effect of the film, a second and a third set of experiments have been performed with the injection point located close upstream the T-junction with the injection such that a thin film only was generated. In the first configuration (far upstream), the pulsation level decreases with increasing liquid rate. The reduction in amplitude compares well with the assumption of added damping in the length between the two side branches. A similar decrease in pulsation amplitude was obtained in the second configuration. However, the amplitude reduction depends on the local liquid flow pattern at the (upstream) side branch and in particular on whether liquid bypasses the side branch or it interferes with the shear layer. This indicates that acoustical damping is the main effect and small amounts of liquid do not significantly interfere with the shear layer.

Full textAbstract:
In process installations with closed side branches, flow induced pulsations (FIP) are a well known phenomenon, which has been extensively studied. The cause of this phenomenon is vortex shedding in the T-connection between the main pipe and the side branch. In literature, only cases with zero flow into the side branch (‘cross flow’) have been studied and identified as a source of pulsations. In this paper, it is shown that with a small cross flow — either leaking into the main pipe or leaking out of the main pipe — also flow-induced pulsations can be excited by vortex shedding in the T-connection. By using a vortex blob method it has been demonstrated that cross flows even up to 25% of the main flow lead to significant FIP source strength. With increasing cross flow merging from the side branch into the main flow, the maximum source strength shifts to slightly lower Strouhal number due to the increased convective velocity of the vortex structures. The source strength decreases rapidly for increasing cross flow. As a rule of thumb, the source strength becomes negligible for cross flows larger than 25% of the total flow. The results of this analysis can be used in the design of process installations, in particular flow metering and mixing stations, where combinations of open and closed side branches occur, as well as merging flows.

Full textAbstract:
A novel form of gas turbine blade or vane cooling in which passages repeatedly branch within the wall of the cooled component is introduced in this paper. These so called dendritic cooling geometries offer particular performance improvements compared to traditional cooling holes where the external cross flow is low, and conventional films have a tendency to lift off the surface. In these regions improved internal cooling efficiency is achieved, while the coolant film is ejected at a low momentum ratio resulting in reduced aerodynamic losses between the film and hot gases, and a more effective surface film. By varying the number of branches of the systems at a particular location it is possible to tune the flow and heat transfer to the requirements at that location whilst maintaining the pressure margin. The additional loss introduced using the internal branching structure allows a full film-coverage arrangement of holes at the external blade surface. In this paper the results of transient heat transfer experiments characterising the internal heat transfer coefficient distribution in large scale models of dendritic passages are reported. Experiments were conducted with 1, 2 and 3 internal flow branches at a range of engine representative Reynolds numbers and exit momentum ratios. CFD models are used to help explain the flow field in the cooling passages. Furthermore the sensitivity of the pressure loss to the blowing ratio at the exit of the cooling holes is characterised and found to be inversely proportional to the number of branches in the dendritic system. Surprisingly the highly branched systems generally do not exhibit the highest pressure losses.

Full textAbstract:
In this paper, an innovation approach was used to estimate the pressure drops in the microchannel. The approach took a simple way to calculate the pressure drops, which could reduce the necessity of an embedded pressure sensor inside microchannel. The concept was to design the rectangular branch-channel along the side wall of main flow in the microchannel. When the fluidic flowed through the microchannel, the bubbles would be formed inside the branch-channel. By observing the changes of the bubbles sizes, the pressure drops around the particular sites of the branch-channel could be estimated. As the experiment results, we could indirectly obtain the pressure drops of the micro fluidic around the micro channel by the changes of the bubbles sizes. In addition to demonstrate the estimating of the pressure drops and the concept of the branch-channel design, it has also supported a frame of the channel sizes and the pressure drops to design the proper microchannel.

Two intersecting cylindrical shells subjected to internal pressure and external moment are of common occurrence in pressure vessel and piping industry. The highest stress intensity occurring in the vicinity of junction, which is a complex space curve when the diameter ratio d/D increases. As the new process of theoretical solution and design criteria research developed by the authors, the stress analysis based on the theory of thin shell is carried out for cylindrical shells with normally intersecting nozzles subjected to three kinds of external branch pipe moments. The thin shell theoretical solution for the main shell with cutout, on which a moment is applied, is obtained by superposing a particular solution on the homogeneous solution. The double trigonometric series solution of cylindrical shell subjected to arbitrary distributed normal and tangential forces based on Timoshenko equation is used for the particular solution and the Xue et al.’s solution, for the homogeneous solution based on the modified Morley equation instead of the Donnell shallow shell equation. The displacement function solution for the nozzle with a nonplanar end is obtained on the basis of the Goldenveizer equation instead of Timoshenko’s. The presented results are in good agreement with those obtained by experiments and by three-dimensional finite element method. The present analytical results are in good agreement with WRC Bulletin 297 when d/D is small. The theoretical solution can be applied to d/D ≤ 0.8, λ = d/DT ≤ 8 and d/D ≤ t/T ≤ 2 successfully.

Full textAbstract:
Despite recent great progress on semantic segmentation, there still exist huge challenges in medical ultra-resolution image segmentation. The methods based on multi-branch structure can make a good balance between computational burdens and segmentation accuracy. However, the fusion structure in these methods require to be designed elaborately to achieve desirable result, which leads to model redundancy. In this paper, we propose Meta Segmentation Network (MSN) to solve this challenging problem. With the help of meta-learning, the fusion module of MSN is quite simple but effective. MSN can fast generate the weights of fusion layers through a simple meta-learner, requiring only a few training samples and epochs to converge. In addition, to avoid learning all branches from scratch, we further introduce a particular weight sharing mechanism to realize a fast knowledge adaptation and share the weights among multiple branches, resulting in the performance improvement and significant parameters reduction. The experimental results on two challenging ultra-resolution medical datasets BACH and ISIC show that MSN achieves the best performance compared with the state-of-the-art approaches.

The problems of the executive branch have always been at the center of attention of legal science. Hundreds of articles and books are devoted to them. In the meantime, government theory still has not offered complete definitions on many issues. It is no coincidence that the concept and essence of the executive branch are, to a certain extent, controversial. The article is devoted to the disclosure of the powers and organization of the activities of the executive branch in the Republic of Kiribati. Knowledge of the political system of other states, and in particular of such a territorially complex state, can quite naturally help in modeling the optimal system of the vertical of power for national state studies.

Full textAbstract:
Abstract Percutaneous coronary intervention (PCI) is widely used as a treatment for ischemic heart disease. In particular, a high procedural precision of PCI for the left main coronary artery (LMCA), which supplies coronary artery blood to large amount of myocardium, is required. The restenosis after stent placement and target lesion revascularization of side branches (SB) is still a clinical issue. Regarding the stent implantation for bifurcation or trifurcation lesion, the stent struts should jail the inlets of SB. In such a situation, we clinically do the kissing balloon technique (KBT) to remove the struts existing at the opening of SB. As well as KBT, the proximal optimization technique (POT), which presses the stent against the wall, is also commonly used. However, merits of therapeutic strategies of KBT and POT for the branch are not confirmed from the fluid-dynamical viewpoint. In this study, we examined the influence of a stent in left main coronary artery on blood flow by employing CFD simulations. We investigated the influence of membrane position on the flow in bifurcation as well as of the stent position and shift on the flow in trifurcation. we confirmed that the effect of the stent position on the flow was bigger than that of the area occupied by the stent and that of KBT which moves the stent from the flow peak may be useful. However, it was also suggested that the intimal lining after KBT may cause serious flow inhibition.

Full textAbstract:
Our study’s main object is travel anthropology, the branch of science that studies the history and nature of man, socio-cultural space, social relations, and structures by gathering information during short and long journeys. The publication aims to research the theoretical foundations and genesis of travel anthropology, outline its fundamental principles, and highlight interaction with related sciences. The article’s defining objectives are the analysis of the synthesis of fundamental research approaches in travel anthropology and their implementation in journalism. When we analyze what methods are used by modern authors, also called «cultural observers», we can return to the localization strategy, namely the centering of the culture around a particular place, village, or another spatial object. It is about the participants-observers and how the workplace is limited in space and time and the broader concept of fieldwork. Some disciplinary practices are confused with today’s complex, interactive cultural conjunctures, leading us to think of a laboratory of controlled observations. Indeed, disciplinary approaches have changed since Malinowski’s time. Based on the experience of fieldwork of Svitlana Aleksievich, Katarzyna Kwiatkowska-Moskalewicz, or Malgorzata Reimer, we can conclude that in modern journalism, where the tools of travel anthropology are used, the practical methods of complexity, reflexivity, principles of openness, and semiotics are decisive. Their authors implement both for stable localization and for a prevailing transition.

Full textAbstract:
Background: Clear allergen communication in food business operators (FBOs) has been shown to have a positive impact on customers’ perceptions of businesses (Barnett et al., 2013). However, the precise size and nature of this effect is not known: there is a paucity of quantitative evidence in this area, particularly in the form of randomised controlled trials (RCTs). The Food Standards Agency (FSA), in collaboration with Kantar’s Behavioural Practice, conducted a feasibility trial to investigate whether a randomised cluster trial – involving the proactive communication of allergen information at the point of sale in FBOs – is feasible in the United Kingdom (UK). Objectives: The trial sought to establish: ease of recruitments of businesses into trials; customer response rates for in-store outcome surveys; fidelity of intervention delivery by FBO staff; sensitivity of outcome survey measures to change; and appropriateness of the chosen analytical approach. Method: Following a recruitment phase – in which one of fourteen multinational FBOs was successfully recruited – the execution of the feasibility trial involved a quasi-randomised matched-pairs clustered experiment. Each of the FBO’s ten participating branches underwent pair-wise matching, with similarity of branches judged according to four criteria: Food Hygiene Rating Scheme (FHRS) score, average weekly footfall, number of staff and customer satisfaction rating. The allocation ratio for this trial was 1:1: one branch in each pair was assigned to the treatment group by a representative from the FBO, while the other continued to operate in accordance with their standard operating procedure. As a business-based feasibility trial, customers at participating branches throughout the fieldwork period were automatically enrolled in the trial. The trial was single-blind: customers at treatment branches were not aware that they were receiving an intervention. All customers who visited participating branches throughout the fieldwork period were asked to complete a short in-store survey on a tablet affixed in branches. This survey contained four outcome measures which operationalised customers’: perceptions of food safety in the FBO; trust in the FBO; self-reported confidence to ask for allergen information in future visits; and overall satisfaction with their visit. Results: Fieldwork was conducted from the 3 – 20 March 2020, with cessation occurring prematurely due to the closure of outlets following the proliferation of COVID-19. n=177 participants took part in the trial across the ten branches; however, response rates (which ranged between 0.1 - 0.8%) were likely also adversely affected by COVID-19. Intervention fidelity was an issue in this study: while compliance with delivery of the intervention was relatively high in treatment branches (78.9%), erroneous delivery in control branches was also common (46.2%). Survey data were analysed using random-intercept multilevel linear regression models (due to the nesting of customers within branches). Despite the trial’s modest sample size, there was some evidence to suggest that the intervention had a positive effect for those suffering from allergies/intolerances for the ‘trust’ (β = 1.288, p<0.01) and ‘satisfaction’ (β = 0.945, p<0.01) outcome variables. Due to singularity within the fitted linear models, hierarchical Bayes models were used to corroborate the size of these interactions. Conclusions: The results of this trial suggest that a fully powered clustered RCT would likely be feasible in the UK. In this case, the primary challenge in the execution of the trial was the recruitment of FBOs: despite high levels of initial interest from four chains, only one took part. However, it is likely that the proliferation of COVID-19 adversely impacted chain participation – two other FBOs withdrew during branch eligibility assessment and selection, citing COVID-19 as a barrier. COVID-19 also likely lowered the on-site survey response rate: a significant negative Pearson correlation was observed between daily survey completions and COVID-19 cases in the UK, highlighting a likely relationship between the two. Limitations: The trial was quasi-random: selection of branches, pair matching and allocation to treatment/control groups were not systematically conducted. These processes were undertaken by a representative from the FBO’s Safety and Quality Assurance team (with oversight from Kantar representatives on pair matching), as a result of the chain’s internal operational restrictions.

Full textAbstract:
The original proposal has three main objectives: a conceptual framework on willingness to pay (WTP) for fruits and vegetables, the introduction of branding and sampling in fresh food, and empirical applications to the United States and Israel. We modified our research plan over time based on availability of data and emergence of new problems. We expanded the range of products to include poultry and the range of techniques to use real experiments as well as more traditional surveys. We expanded the range of problems to understand attitudes toward genetically modified (GM) food. There is a growing interest in introduction of marketing tools like demonstration sampling, money-back guarantees, labeling, and brands in agriculture. These marketing tools are important for enhancing demand for agricultural products and food safety. However, the methodology needed to assess the effectiveness of these tools and understand their performance in different agricultural sectors is limited. Our analysis demonstrated the importance of brands as a marketing tool in agriculture. In particular, we showed conceptually that strong brands can be substitutes for other marketing tools like sampling or demonstration. We were able to conduct real experiments for the demand for safe chicken and show that consumers are willing to pay significantly more for products branded as more safe. Yet, using experiments in Israel and the United States, we found that WTP for brands of fresh fruits and vegetables is smaller than in other product categories. Warning labels are a sort of negative branding. The GM-free labeling is particularly important since it serves as a trade barrier to U.S. crops exports. Our analysis of acceptance of GM products found that WTP for GM products in Israel and the United States depends on framing of information about the impact ofGM and the quantity of information disclosed. Finally, in analyzing the evolution of support for Proposition 37 that aimed to introduce mandatory labeling of GM in California, we found that support for mandatory labeling ofGM products is broad as long as it is not perceived to be costly. Our project demonstrates the feasibility of conducting real experiments to assess consumer demand in agriculture. When looking at interdisciplinary groups, one can design new products and assess the WTP for their characteristics. We also show that, while branding is a very strong marketing tool, its use in fresh fruit and vegetables is likely to be limited. However, brands can be important with processed food. Furthermore, we have proven that, while some consumers strongly object to GM products, most consumers in the United States and Israel would be willing to buy them for a discount, and some would pay extra if they are associated with improved characteristics. Finally, we expanded the notion of warning labels to calorie information and showed that the response to calorie information depends on gender, education, and how the information is presented.

Just, David, and Amir Heiman. Building local brand for fresh fruits and vegetables: A strategic approach aimed at strengthening the local agricultural sector. United States Department of Agriculture, January 2016. http://dx.doi.org/10.32747/2016.7600039.bard.
Full textAbstract:
Abstract The debate about whether to reduce import barriers on fresh produce in order to decrease the cost of living and increase welfare or to continue protecting the local agricultural sector by imposing import duties on fresh vegetables and fruits has been part of the Israeli and the US political dialog. The alternative of building a strong local brand that will direct patriotic feelings to support of the agricultural sector has been previously discussed in the literature as a non-tax barrier to global competition. The motivation of consumers to pay more for local fresh fruits and vegetables are better quality, environmental concerns, altruism, and ethnocentrism. Local patriotic feelings are expected to be stronger among national-religious consumers and weaker among secular left wing voters. This project empirically analyzes consumers’ attitude toward local agricultural production, perceptions of the contribution of the agricultural sector to society and how these perceptions interact with patriotic beliefs and socio-political variables perhaps producing an ethnocentric preference for fruits and vegetables. This patriotic feeling may be contrasted with feelings toward rival (or even politically opposing) countries competing in the same markets. Thus geo-political landscape may help shape the consumer’s preferences and willingness to purchase particular products. Our empirical analysis is based on two surveys, one conducted among Israeli shoppers and one conducted among US households. We find strong influences of nationalism, patriotism and ethnocentrism on demand for produce in both samples. In the case of Israel this manifests itself as a significant discount demanded for countries in conflict with Israel (e.g., Syria or Palestine), with the discount demanded being related to the strength of the conflict. Moreover, the effect is larger for those who are either more religious, or those who identify with right leaning political parties. The results from the US are strikingly similar. For some countries the perception of conflict is dependent on political views (e.g., Mexico), while for others there is a more agreement (e.g., Russia). Despite a substantially different religious and political landscape, both right leaning political views and religiosity play strong roles in demand for foreign produce.

Full textAbstract:
The project objective was to more fully understand how the motion of pollen grains may be controlled by electrostatic forces, and to develop a reliable mechanized pollination system based upon sound electrostatic and aerodynamic principles. Theoretical and experimental analyses and computer simulation methods which investigated electrostatic aspects of natural pollen transfer by insects found that: a) actively flying honeybees accumulate ~ 23 pC average charge (93 pC max.) which elevates their bodies to ~ 47 V likely by triboelectrification, inducing ~ 10 fC of opposite charge onto nearby pollen grains, and overcoming their typically 0.3-3.9 nN detachment force resulting in non-contact electrostatic pollen transfer across a 5 mm or greater air gap from anther-to-bee, thus providing a theoretical basis for earlier experimental observations and "buzz pollination" events; b) charge-relaxation characteristics measured for flower structural components (viz., 3 ns and 25 ns time constants, respectively, for the stigma-style vs. waxy petal surfaces) ensure them to be electrically appropriate targets for electrodeposition of charged pollen grains but not differing sufficiently to facilitate electrodynamic focusing onto the stigma; c) conventional electrostatic focusing beneficially concentrates pollen-deposition electric fields onto the pistill tip by 3-fold as compared to that onto underlying flower structures; and d) pollen viability is adequately maintained following exposure to particulate charging/management fields exceeding 2 MV/m. Laboratory- and field-scale processes/prototype machines for electrostatic application of pollen were successfully developed to dispense pollen in both a dry-powder phase and in a liquid-carried phase utilizing corona, triboelectric, and induction particulate-charging methods; pollen-charge levels attained (~ 1-10 mC/kg) provide pollen-deposition forces 10-, 77-, and 100-fold greater than gravity, respectively, for such charged pollen grains subjected to a 1 kV/cm electric field. Lab and field evaluations have documented charged vs. ukncharged pollen deposition to be significantly (a = 0.01-0.05) increased by 3.9-5.6 times. Orchard trials showed initial fruit set on branches individually treated with electrostatically applied pollen to typically increase up to ~ 2-fold vs. uncharged pollen applications; however, whole-tree applications have not significantly shown similar levels of benefit and corrective measures continue. Project results thus contribute important basic knowledge and applied electrostatics technology which will provide agriculture with alternative/supplemental mechanized pollination systems as tranditional pollen-transfer vectors are further endangered by natural and man-fade factors.

Hotsur, Oksana. SOCIAL NETWORKS AND BLOGS AS TOOLS PR-CAMPAIGN IMPLEMENTATIONS. Ivan Franko National University of Lviv, March 2021. http://dx.doi.org/10.30970/vjo.2021.50.11110.
Full textAbstract:
The article deals with the ways in which social networks and the blogosphere influence the formation and implementation of a PR campaign. Examples from the political sphere (election campaigns, initiatives), business (TV brands, traditional and online media) have revealed the opportunities that Facebook, Telegram, Twitter, YouTube and blogs promote in promoting advertising, ideas, campaigns, thoughts, or products. Author blogs created on special websites or online media may not be as much of a tool in PR as an additional tool on social media. It is noted that choosing a blog as the main tool of PR campaign has both positive and negative points. Social networks intervene in the sphere of human life, become a means of communication, promotion, branding. The effectiveness of social networks has been evidenced by such historically significant events as Brexit, the Arab Spring, and the Revolution of Dignity. Special attention was paid to the 2019 presidential election. Based on the analysis of individual PR campaigns, the reasons for successful and unsuccessful campaigns from the point of view of network communication, which provide unlimited multimedia and interactive tools for PR, are highlighted. In fact, these concepts significantly affect the effectiveness of the implementation of PR-campaign, its final effectiveness, which is determined by the achievement of goals. Attention is drawn to the culture of communication during the PR campaign, as well as the concepts of “trolls”, “trolling”, “bots”, “botoin industry”. The social communication component of these concepts is unconditional. Choosing a blog as the main tool of a marketing campaign has both positive and negative aspects. Only a person with great creative potential can run and create a blog. In addition, it takes a long time. In fact, these two points are losing compared to other internet marketing tools. Further research is interesting in two respects. First, a comparison of the dynamics of the effectiveness of PR-campaign tools in Ukraine in 2020 and in the past, in particular, at the dawn of state independence. Secondly, to investigate how/or the concept of PR-campaigns in social networks and blogs is constantly changing.

Climate change will increase weather induced risks to forests, and thus effective adaptation measures are needed. In Säätyö project funded by the Ministry of Agriculture and Forestry, we have summarized the data that facilitate adaptation measures, developed weather and climate services that benefit forestry, and mapped what kind of new weather and climate services are needed in forestry. In addition, we have recorded key further development needs to promote adaptation. The Säätyö project developed a service product describing the harvesting conditions of trees based on the soil moisture assessment. The output includes an analysis of the current situation and a 10-day forecast. In the project we also tested the usefulness of long forecasts beyond three months. The weather forecasting service is sidelined and supplemented by another co-operation project between the Finnish Meteorological Institute and Metsäteho called HarvesterSeasons (https://harvesterseasons.com/). The HarvesterSeasons service utilizes long-term forecasts of up to 6 months to assess terrain bearing conditions. A test version of a wind damage risk tool was developed in cooperation with the Department of Forest Sciences of the University of Eastern Finland and the Finnish Meteorological Institute. It can be used to calculate the wind speeds required in a forest area for wind damage (falling trees). It is currently only suitable for researcher use. In the Säätyö project the possibility of locating the most severe wind damage areas immediately after a storm was also tested. The method is based on the spatial interpolation of wind observations. The method was used to analyze storms that caused forest damages in the summer and fall of 2020. The produced maps were considered illustrative and useful to those responsible for compiling the situational picture. The accumulation of snow on tree branches, can be modeled using weather data such as rainfall, temperature, air humidity, and wind speed. In the Säätyö project, the snow damage risk assessment model was further developed in such a way that, in addition to the accumulated snow load amount, the characteristics of the stand and the variations in terrain height were also taken into account. According to the verification performed, the importance of abiotic factors increased under extreme snow load conditions (winter 2017-2018). In ordinary winters, the importance of biotic factors was emphasized. According to the comparison, the actual snow damage could be explained well with the tested model. In the interviews and workshop, the uses of information products, their benefits, the conditions for their introduction and development opportunities were mapped. According to the results, diverse uses and benefits of information products and services were seen. Information products would make it possible to develop proactive forest management, which would reduce the economic costs caused by wind and snow damages. A more up-to-date understanding of harvesting conditions, enabled by information products, would enhance the implementation of harvesting and harvesting operations and the management of timber stocks, as well as reduce terrain, trunk and root damage. According to the study, the introduction of information is particularly affected by the availability of timeliness. Although the interviewees were not currently willing to pay for the information products developed in the project, the interviews highlighted several suggestions for the development of information products, which could make it possible to commercialize them.
