Full textAbstract:
Grassmann's Ausdehnungslehre is an algebra that directly refers to and combines geometric figures and their incidence relations, with arbitrary Cartesian coordinates relegated to their properly auxiliary role, and equally arbitrary symbol strings relegated to their secondary role. Grassmann's philosophical introduction is essentially one of the first expositions of the rudimentary principles of what today might be called universal algebra. The content appears to be a simple and clear natural scientist's version of the basic principles of dialectical materialism, as applied to the formal sciences. Grassmann insists that his reason for including the philosophical introduction is an attempt to provide an orientation to help the student form for himself the proper estimation of the relation between general and particular at every stage of the learning process. His formulation that philosophy moves from general to particular, and mathematics from particular to general, can be traced to Kant.

This article examined the importance of functioning of the branch in the system of national economy, in particular, scientific approaches (technological and economical) concerning subjects of such an economy. It is determined that the branch structure of the national economy reflects the social division of labor. It has been established that the significant economic potential of the national economy is determined the ability of the branches of such economy to produce products and/ or to provide high-quality services which involve high value added. The branch structure in the national economy has been defined, in particular, the status of individual branch in such an economy. Active interventional of state authorities which are responsible for economic policy on regulation of functioning of branches the national economy, which do not normally require such regulation (tourism, culture, and art, etc.) in connection with the spread of COVID-19, has been established. It is proved that demand for products produced by enterprises of a particular branch can have a direct influence on the development of other branches of the national economy.

Full textAbstract:
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.

In the article substantiate the fundamental concept of «the content of physical education of servicemen» for the theory and methodology of physical education of servicemen and to focus on the need to optimize the content of physical education of servicemen in the conditions of performing combat missions to protect the state from the russian aggressor. It has been found that the content of physical education of servicemen should include theoretical and practical knowledge of their physical education and physical awareness - physical fitness and readiness - as military professionals for successful military professional activities; this includes the following knowledge: physical culture and sports of servicemen in general and of a particular type and branch of the military, in particular; healthy lifestyle of servicemen as subjects of extreme activities; a set of practical physical skills, abilities and capacities of servicemen of a particular type and branch of the armed forces necessary for successful life in the military environment and practical knowledge about their formation, development and improvement; a set of professionally important physical qualities of servicemen of a particular type and branch of the armed forces necessary for the successful implementation of job competencies in the military environment and practical knowledge about their formation, development and improvement; physical fitness of servicemen for military professional activities as military professionals of a particular type and branch of the armed forces and about the relevant organizational forms, methods of physical education and means of its formation, development, improvement and maintenance; physical readiness of servicemen for military professional activity as military professionals of a particular type and branch of the armed forces and about the relevant organizational forms, methods of physical education and means of its formation, development and maintenance. The results of the theoretical and empirical research clearly demonstrated that the problem of the content of physical education of military personnel is an urgent theoretical and applied problem for the theory and methodology of their physical education in various types and branches of the armed forces.

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.

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:
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.

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 vent<br>Efficiently 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.

Full textAbstract:
Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico<br>Estudaremos 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 Ã X 5 onde X 5 Ã 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) Ã 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 Ã o responsÃvel pela desingularizaÃÃo do espaÃo<br>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

Previous issue date: 2013-02-05<br>CNPq<br>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.<br>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.

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 monograph presents the modern concept of identification of firearms. The processes of weapons production necessitated adjustments to the traditional foundations of forensic ballistic identification, and a third group, subclass (subgroup) signs, is included in the binary system of general and particular signs of traces. An analysis of the modern practice of identifying firearms shows that the main obstacles in this process are subclass characteristics and prejudice. The first are related to the manufacture of parts and parts of weapons, and prejudice is associated with the subjective interpretation by an expert of the results of comparing signs in traces, which underlies the formation of conclusions of a comparative study.
 In addition, currently an urgent task is to confirm the ability of a qualified expert to draw reliable conclusions on identification.
 For students, cadets, trainees, postgraduates, adjuncts and teachers of the faculties of training forensic experts, as well as practitioners in the field of forensic ballistics and anyone interested in this branch of knowledge.

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.

Farhutdinov, Insur. The evolution of international law - from Westphal to Versailles. INFRA-M Academic Publishing LLC., 2024. https://doi.org/10.12737/2135819.
Full textAbstract:
Based on doctrinal research, the monograph examines the stages of the emergence and evolution of international law from the Treaty of Westphalia in 1648 to the Treaty of Versailles in 1919. The Westphalian-Vienna system of international relations, which is the subject of these studies, is of particular importance for the evolution of international law. The research is devoted to the history of the branch of the science of international law, which studies the emergence and development of public international law as a set of legal norms governing interstate relations. The formation of international law began with the fundamental work of Hugo Grotius "Three Books on the Law of War and Peace" (1625). The Dutch scientist developed humanistic rules of warfare, which later became the basis of the law of armed conflict in the system of international law. The work shows that the myth of Westphalus created a system of beliefs that are far from reality. Based on the international legal analysis of historical texts, the generally accepted doctrine that the Treaty of Westphalia is, however, the beginning of a new international system that has stood up to the XXI century is being questioned. It is intended for students, postgraduates, as well as for anyone interested in the problems of the history of international law and international relations. It is recommended for use as a textbook in the disciplines of "International Law", "International Relations".

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:
Is the American judiciary still the least dangerous branch, as Alexander Hamilton and legal scholar Alexander Bickel characterized it? Unlike legislatures or administrative agencies, courts do not make policy so much as direct and redirect policy as it is implemented. The judicial contribution to policymaking involves the infusion of constitutional rights into the realm of public policy, and as the government has grown, the courts have become more powerful from doing more and more of this. Powers and Rothman explore the impact of the federal courts, providing a brief account of the development of constitutional law and an overview of the judiciary's impact in six controversial areas of public policy. •Busing •Affirmative action •Prison reform •Mental health reform •Procedural reforms in law enforcement •Electoral redistricting In each of these areas, the authors review significant cases that bear on the particular policy, exploring the social science evidence to assess the impact of the courts on policies—and the consequences of that intervention. Powers and Rothman conclude that judicial intervention in public policy has often brought about undesirable consequences, sometimes even for the intended beneficiaries of government intervention.

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.

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.

Full textAbstract:
Abstract The United States has had a diplomatic presence in Québec for some 200 years, and now has two consulates, one in Québec City and one in Montréal. Québec opened its first delegation to the U.S. nearly 85 years ago, during the Second World War. Despite Québec's strong commercial and security interests in the United States, it is almost impossible for a Québec premier to secure a bilateral meeting with an American president. In fact, there are very few precedents. In the United States, Québec does not enjoy direct and privileged ties with the president or members of the executive branch of the U.S. federal government, as it does with France. Despite this, Québec has nonetheless sought to increase its leverage in the United States since the 1960s. This chapter chronicles the efforts of Québec to advance its interests by examining efforts of successive provincial governments to institutionalize and deepen its political relationship with the United States through direct engagement with the American executive and legislative branches of government. In particular, a range of paradiplomatic efforts constructed and pursued by Québec between 1940 and 2000, are identified and closely evaluated.

Full textAbstract:
This study accounts for the grammaticalization of the verb -maɾa ‘finish’ in the language varieties of the Western Serengeti branch of the Mara subgroup of Eastern Bantu. In these varieties, -maɾa is found in two different auxiliary verb constructions marking the two interrelated Phasal Polarity concepts of already and not yet. Whereas ‘finish’ in general and -maɾa cognates in particular are commonly grammaticalized into already in Bantu, the parallel development of a not yet ‑marker from the same source constitutes a much rarer development. Nonetheless, we propose that both constructions developed out of the same need to reinforce a reading of (non-)completion (and counter-factuality) and that they instantiate recurrent cyclic patterns of change significant for Eastern Bantu more broadly.

Full textAbstract:
This chapter explores the ways in which photojournalism (specifically animal activist photography of domesticated animals) functions as translation and, in particular, knowledge translation. Referring broadly to the synthesis, exchange, and application of knowledge produced during research processes, knowledge translation actively bridges the chasm between the acquisition of knowledge and application of knowledge. By providing visual information that verbal communication would otherwise not be able to convey, animal activist photography is not only a translational process of the knowledge of the activist/photographer behind the lens, but also the plight of the animal in front of the lens. Furthermore, by approaching this study within ecosemiotics, a branch of semiotics that explores the human relationships to nature this chapter engages with the human/non-human relations that are represented by animal activist photojournalism.

In The 35th European Symposium on Computer Aided Process Engineering. PSE Press, 2025. https://doi.org/10.69997/sct.125995.
Full textAbstract:
Artificial neural networks are widely used as data-driven models for capturing complex, nonlinear systems. However, suboptimal training remains a significant challenge due to the nonlinearity of activation functions and the reliance on local solvers, which makes achieving global solutions difficult. One solution involves reformulating activation functions as piecewise linear approximations to convexify the problem, though this approach often requires substantial CPU time. This study demonstrates that a tailored branch-and-bound algorithm can effectively address these challenges by efficiently navigating the solution space using linear relaxations. The proposed method achieves minimal training error, offering a robust solution to the training bottleneck. Unlike traditional mixed-integer programming approaches, which often struggle to converge within reasonable CPU times, the SOSX algorithm shows superior scalability, with computational demand growing almost linearly rather than exponentially as problem size increases. Experiments on datasets with the same dimensionality confirm that the algorithm's efficiency is not specific to a particular dataset, as it demonstrates consistent CPU time trends across multiple datasets.

In Foundations of Computer-Aided Process Design. PSE Press, 2024. http://dx.doi.org/10.69997/sct.105466.
Full textAbstract:
The synthesis of energy systems necessitates simultaneous optimization of both design and operation across all components within the energy system. In real-world applications, this synthesis poses a mixed-integer nonlinear programming (MINLP) problem, considering nonlinear behaviours such as investment cost curves and part-load performance. The complexity increases further when seasonal energy storage is involved, as it requires temporal coupling of the full time series. Although numerous solution approaches exist to solve the synthesis problems simplified by linearization, methods for solving a full-scale problem are currently missing. In this work, we introduce a rigorous method, RiNSES4, to manage the nonlinear aspects of energy system synthesis, particularly focusing on long-term time-coupling constraints. RiNSES4 calculates the upper and lower bounds of the initial synthesis problem in two separate branches. The proposed method yields feasible solutions through upper bounds, while evaluating the solution quality via lower bounds. The solution quality is iteratively enhanced by increasing the resolution for calculating upper bounds and tightening the relaxations for computing lower bounds. Both branches work simultaneously and independently, with their outcomes compared after each iteration within each branch. The iterations continue until a predefined optimality gap is reached. We apply RiNSES4 to design a photovoltaic and battery energy system, considering the seasonality of both energy supply and demand sides. In comparison with a state-of-the-art commercial solver, RiNSES4 enables to solve the MINLP synthesis problem with great temporal detail and shows high potential.

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:
Abstract In vibration service, small-bore piping connections, especially unsupported cantilever configurations, are associated with a high level of concern as potential fatigue crack initiation locations. Various international guidelines and procedures address the assessment of piping vibration in general and of small-bore connections in particular. In this work, a review of these guidelines as applied to a specific class of small-bore connection was performed by means of a finite element parametric study on a large number of branch connections. The small-bore configuration evaluated in this work is an unsupported cantilever connection made using an integrally reinforced forged branch fitting with butt-welded joints. At the end of the branch is a flanged connection with either a blind flange only, or a single or double valve with a blind flange. For the parametric study a random distribution of run pipe diameter and thickness and branch pipe diameter, thickness, and length was used to evaluate a few thousand different small-bore configurations. Modal analysis was used to determine the relationship between stress and velocity at two critical locations: the weld between the branch fitting and header and the weld between the branch pipe and branch fitting. Results of the parametric study were processed and compared to the evaluation criteria of a number of established and upcoming guidelines and standards.

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.

Full textAbstract:
Environmental law is an important and dynamically developing branch of the legal system, which plays a key role in ensuring sustainable interaction between human society and nature. In the modern world, where environmental threats are becoming more and more obvious, this area of law is of particular importance. It pays special attention to environmental protection, responsibility for violations of environmental standards, support for sustainable development and international cooperation. Environmental law is based on the understanding that the environment is an irresistible and indispensable component of our lives. It recognizes the ecological value of natural objects such as water and forest lands, air, soil and living organisms. Environmental law also takes into account the global nature of environmental issues. In the light of global climate change and the threat of biodiversity loss, cooperation and coordination at the international level are becoming increasingly important. Environmental law encourages international cooperation and the development of an international framework aimed at protecting the environment. One of the basic principles of environmental law is the principle of preventing harmful effects on the environment. This implies not only responsibility for activities that may damage the ecosystem, but also a preliminary study of the possible negative consequences of any actions. Environmental law is aimed at creating and maintaining environmental sustainability in the interests of todays and future generations. The article discusses various aspects of environmental law: its concept, subject, methods, as well as the main functions and tasks that it performs.

Full textAbstract:
In the first two phases of this project, the accuracy and reliability of both conventional and more advanced nondestructive inspection techniques were evaluated by way of a round-robin program of blind inspections The results indicate that there is much variability in the accuracy and reliability of discontinuity detection and sizing depending on details of the NDT procedures adopted, which includes specification of equipment, techniques, calibration methods, and reporting requirements. In Phase III, optimized procedures for sleeve fillet welds and a limited number of branch groove welds were developed in the laboratory using fabricated assemblies containing Intentionally placed discontinuities. In response to a recommendation in Phase Ill, the current phase developed optimized procedures for a wide range of branch groove welds. The results of this phase indicate that the reliability and accuracy of nondestructive inspection techniques is not as high as obtained for sleeve fillet welds in the previous phase of the program In particular, the detection of sub-surface discontinuities by ultrasonic inspection is made more difficult by the added complexity of the branch weld geometries. As with sleeve fillet welds however, the probability of detecting weld toe cracks of a significant size can be quite good.

Full textAbstract:
The article conducts an analysis of the content of regional Public Television during the full-scale Russian-Ukrainian war. A comparative analysis of programs created by regional teams of the Public broadcaster before the full-scale invasion is presented. The research aims to study and provide a detailed analysis of the television content of regional branches of Public Television to understand the peculiarities of operation during a state of war, track changes in the thematic content, and speech format. Analytical methods of scientific research (analysis of television content of regional branches of Public Television), as well as inductive, deductive, and abstract-logical methods, are employed. The historical method is applied to the study of television reform in Ukraine. The key method in the research is content analysis, which is used to study the impact of television reform on the quality and volume of content of regional branches of Public Television. Using the example of the content of “Suspilne-Ternopil,” the thematic and problematic content of programs of the regional branch of Public Television is investigated. A significant reduction in the share of in-house produced content on local issues is identified. In particular, at the beginning of the full-scale invasion, the production of the program “Today. Main” was suspended, a socio-political talk show that extensively covered local issues. Emphasis is placed on the importance of regional media in times of war, representing the interests of the public at both regional and central levels. In our opinion, regional broadcasters of Public Television should reintroduce in-house produced programs to restore a platform for discussing local issues. Strengthening ties with high-quality media from neighboring states is also advisable, specifically for the exchange of journalists’ experiences and high-quality content. Keywords: Public television, television reform, Russian-Ukrainian war, television content, broadcast, regional branch.

Unknown, Author. L51602 Criteria for Hot Tap Welding Further Studies. Pipeline Research Council International, Inc. (PRCI), 1989. http://dx.doi.org/10.55274/r0010102.
Full textAbstract:
In the gas transmission industry there is a frequent need for modification of existing pipework. Modifications are made primarily by welding on additional pipes and branch connections to existing pipelines. The associated costs of shutting down a pipeline creates a situation whereby it becomes economically feasible to weld onto pipelines containing flowing, pressurized products. The risk of burn through and in particular, the susceptibility to cracking are greatly increased by the rapid cooling rates associated with the high heat sink effect of the flowing gas and in turn can result in excessive hardening of the heat affected zone in ferritic steels. Edison Welding Institute developed new criteria for safe hot tap welding procedures on all ferritic steels. Their approach is based on correlating field measurements of the ability of the pipe to conduct heat (i.e., its heat-sink capacity) to the cooling rate of the weld. Laboratory welding trials with simulated branch and sleeve connections on live pipelines containing natural gas were used to validate the new criteria. The results indicate that structurally sound hot tap repairs can be made with a high level of confidence.

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:
The presidential politics literature depicts presidents either as all-powerful actors or figureheads and seeks to explain outcomes accordingly. The president and the executive branch are nonetheless usually treated as black boxes, particularly in developing countries, even though the presidency has evolved into an extremely complex branch of government. While these developments have been studied in the United States, far less is known in other countries, particularly in Latin America, where presidential systems have been considered the source of all goods and evils. To help close the knowledge gap and explore differences in policymaking characteristics not only between Latin America and the US but also across Latin American countries, this paper summarizes the vast literature on the organization and resources of the Executive Branch in the Americas and sets a research agenda for the study of Latin American presidencies.

McPhedran, R., K. Patel, B. Toombs, et al. Food allergen communication in businesses feasibility trial. Food Standards Agency, 2021. http://dx.doi.org/10.46756/sci.fsa.tpf160.
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:
Electric vehicles (EVs) play a significant role in enhancing the sustainability of transportation systems. However, their widespread adoption is hindered by inadequate public charging infrastructure, particularly to support long-distance travel. Identifying optimal charging station locations in large transportation networks presents a well-known NP-hard combinatorial optimization problem, as the search space grows exponentially with the number of potential charging station locations. This report introduces a quantum search-based optimization algorithm designed to enhance the efficiency of solving this NP-hard problem for both corridors and transportation networks. By leveraging quantum parallelism, amplitude amplification, and quantum phase estimation as a subroutine, the optimal solution is identified with a quadratic improvement in complexity compared to classical exact methods, such as branch and bound. The detailed design and complexity of a resource-efficient quantum circuit are discussed.

Full textAbstract:
The article analyzes the state of development of Ukrainian advertising in the conditions of the Russian-Ukrainian war. Studying the work of Ukrainian advertising agencies during the war is a unique experience of Ukrainian specialists during the war. The article emphasizes that Ukrainian advertising agencies have become an example for global corporations with their resilience and courage. The study of the place of Ukrainian advertising agencies in the world system made it possible to state that the domestic industry is developing in step with the world one. This was facilitated by the fact that Ukrainians quickly adapt to modern technologies and catch global trends. In some areas of advertising, Ukrainian agencies are one step ahead of European and American ones. Communication with Ukrainian heads of advertising campaigns, marketers and target specialists, who were directly involved in the “rescue” of companies at the beginning of the war, made it possible to find out how the business development strategy changed, what tactical solutions they used at the beginning of the war, and how they optimized the work of the team. The results of the research give grounds for asserting that in the conditions of the Russian-Ukrainian war, many brands have developed new rules for content and communication in social networks. The content strategy of brands needs maximum adaptation to new realities. The traditional division of content into branded, selling, fan and interactive content is losing its relevance. This market niche is occupied by social, supportive and useful content. In particular, as an example of social brand content, we can name: the national position of an advertising agency, support of the Armed Forces of Ukraine, assistance to consumers, new adapted services, HR information about agency support, assistance to temporarily displaced persons, volunteering. Ukrainian advertising agencies were able to quickly adapt to the conditions of the war, entered international markets, took care of their employees and continue their work. Keywords: advertising, agencies, Russian-Ukrainian war, social networks, work with clients, personnel problems.
