Full textAbstract:
Combining ability effects were estimated in line x tester crossing programme for fifteen characters involving ten lines and four testers in Triticum durum. It revealed preponderance of non-additive gene action for grain yield plant along with other character like grain number / spike, 1000 grain weight, protein content, sedimentation value and B-carotene, which suggests scope for improvement of these characters through heterosis breeding and transgressive segregants for evolving high yielding superior genotypes. HI 8591, HI 8596 and HD 4692 among lines and Bij Red and HG 110 among testers were evaluated as good general combiners. Among hybrids, HD 4694 x Bij Red, HI 8381 x MPO 215, HI 8591 x MPO 215, HI 8591 xHG 110, HI 8596x MPO 215 and HI 8653 x Bij Red were the most promising ones as they had high SCA effect and per se performance for grain yield plant and its component characters. An attempt of multiple crosses with the use of all the above good general combiners would lead to obtain transgressive segregants for grain yield in advanced generations.

Full textAbstract:
Abstract A new intergeneric hybrid manakin is characterized using morphological characters and mitochondrial and nuclear DNA sequences. Many morphological traits suggest the bird is intermediate between Ilicura militaris and Chiroxiphia caudata. Sequences of the maternally inherited mitochondrial ND2 gene demonstrate the female parent to be Chiroxiphia caudata, and the nuclear beta-fibrinogen intron 5 sequences can not eliminate Chiroxiphia and Ilicura as parents. Therefore, DNA sequence data lead to the conclusion that Ilicura is the male parent of this unusual bird. This study is important because it highlights the significance of using multiple character systems in diagnosing unusual bird specimens.

Full textAbstract:
In this paper, the Linnaean hierarchy is discussed as the taxonomic model for the evolutionary differentiation of the earth’s biota. This model allows us to understand why a number of ideas and arguments in the evolutionary theory are unfortunate. Among these is the idea of a linear ladder of nature («scala natura»). The arguments about species constancy versus species variability, natural species versus «artificial» higher taxa, a single type of animals versus multiple types, as well as about the connection versus disconnection of microevolution and macroevolution are meaningless. Two kinds of phylogeny are considered. The first reflects the appearance of new characters in the course of evolution, and their sequence provides the nesting hierarchy of groups. The second reflects the appearance of new character states and provides a basis for the diversity of taxa at each hierarchical level. The taxonomic hierarchy is an embodiment of the first kind of phylogeny and does not require the tracing of ancestors and descendants along the lines of character development. Character ranking and the improvement of a tentative taxonomic hierarchy with the help of a posteriori weighting of differences are discussed. The method of character weighting leads to the construction of prognostic combinatorial arrangements that can predict the existence of organisms with certain character state combinations at each hierarchical level. The drawbacks of cladistic methodology, especially the «synapomorphy principle», the «dichotomy principle», and the monophyly «definition» through the internal composition of groups, are noted. It is pointed out that these principles only lead to the creation of heterogeneous groups and wrong character ranking.

In the regions of Chinese as the first language, children with backward Chinese characters ability are more likely to give up reading the subject content of long texts, which affects their learning in the long term. This study applies augmented reality (AR) to develop a remedial teaching model for Chinese radical recognition and assesses its effectiveness on underachieved students at an elementary school. Based on several Chinese characters that were easy for children to confuse radicals, an AR app for Android was developed and installed in tablet computers. The remedial teaching model involves students to use AR app to scan radical cards and trigger animations introducing the evolution of radicals. Students can practice Chinese character writing on the tablet computer's screen. With the multiple stimulus of AR, the teacher lead students collaboratively complete the worksheets. To assess students' learning outcomes, a quasi-experimental approach was administrated to 8 second grade students who had backward Chinese literacy, in which qualitative and quantitative data were collected. Results showed this remedial teaching model improved the disadvantaged students’ recognition accuracy on Chinese characters and flips their motivation toward Chinese characters learning. During the remedial teaching program, use of AR was effective to get students more attentions and impressions on Chinese radicals. Finally, Implications for Chinese characters teaching practices are discussed

This content analysis study sheds light on the gender inequality in popular children’s animated films. The dataset uses the North American theater grosses to rank the most popular 150 animated children’s films from 1990-2020. We found multiple patterns of gender inequality related to speaking roles, lead characters, physical portrayals, social roles, interpersonal relationships, and even the creators of the films. Male characters had three times as many speaking roles as female characters and had the lead role in 80% of the films. Correspondingly, 80% of the film creators (writers, directors, and producers) were male. Films that passed the Bechdel test had twice as many female writers as those that failed the test. The inequality and gender stereotyping one sees in the real world is reflected in this study of children’s films. Animated films are a popular media outlet for children, and this study highlights the impact that these skewed representations can have on children.

The research discusse joke strategies in American situational comedy How I Met You Mother (HIMYM). The purpose of this research is to identify; (1) the joke strategies in situational comedy HIMYM (2) The pragmatic meaning of jokes that are expressed by the characters in HIMYM AND (3) Pragmatic prank functions that are expressed by the characters in HIMYM. This research is categorized as descriptive linguistic research. Observation method applied in data collection, while the method of distribution and matching applied in analyzing data. The results of this research data analysis is presented using informal and formal methods. From the results of data analysis found 14 strategy joke uttered by characters in a situational comedy American HIMYM, namely: ambiguity, grammar, syllabics, idiomatics, questionable English, antonymics, style, negativism, lexicography, spelling, punctuation, Rhyming English, numerical English And part of speech. The dominant strategy used is ambiguity because there are many words in English that mean more than one and are likely to lead the listener to multiple interpretations. The jokes uttered by the characters in situational comedy HIMYM have assertive, expressive and directive meanings. Moreover, the joke also serves to show the power, solidarity and psychological defense of the speaker.

Full textAbstract:
This study offers a reading of Richard Wagner's Die Meistersinger von Nüürnberg in relation to compositional rules. By separating the latter into categories of rhetorical and tonal rules, one may determine first if either set of rules is followed adequately by the various characters in the opera, and also whether the rules themselves are sufficient for the composition of master songs. The rhetorical rules are abstracted from the libretto, while tonal rules are the principles of harmony and counterpoint as understood within Heinrich Schenker's theory of tonality. The essay focuses specifically on Walther's songs "An stillen Herd," "Fanget An!," and the multiple verses and versions of the Morning Dream/Prize Song. Close analyses of these songs lead to a better understanding of what Wagner may have intended to teach his characters and his audience about compositional rules.

PhytoKeys 152 (July 7, 2020): 27–104. http://dx.doi.org/10.3897/phytokeys.152.49604.
Full textAbstract:
Close scrutiny of Goodenia (Goodeniaceae) and allied genera in the ‘Core Goodeniaceae’ over recent years has clarified our understanding of this captivating group. While expanded sampling, sequencing of multiple regions, and a genome skimming reinforced backbone clearly supported Goodenias.l. as monophyletic and distinct from Scaevola and Coopernookia, there appears to be no synapomorphic characters that uniquely characterise this morphologically diverse clade. Within Goodenias.l., there is strong support from nuclear, chloroplast and mitochondrial data for three major clades (Goodenia Clades A, B and C) and various subclades, which lead to earlier suggestions for the possible recognition of these as distinct genera. Through ongoing work, it has become evident that this is impractical, as conflict remains within the most recently diverged Clade C, likely due to recent radiation and incomplete lineage sorting. In light of this, it is proposed that a combination of morphological characters is used to circumscribe an expanded Goodenia that now includes Velleia, Verreauxia, Selliera and Pentaptilon, and an updated infrageneric classification is proposed to accommodate monophyletic subclades. A total of twenty-five new combinations, three reinstatements, and seven new names are published herein including Goodenia subg. Monochila sect. Monochila subsect. Infracta K.A.Sheph. subsect. nov. Also, a type is designated for Goodenia subg. Porphyranthus sect. Ebracteolatae (K.Krause) K.A.Sheph. comb. et stat. nov., and lectotypes or secondstep lectotypes are designated for a further three names.

Article’s fundamental is an elemental example of agent system (and derivatively multiagent system) utilization by means of computer technology, which represents so – called computer malingering or computer simulation method. Next to classical word argumentations and mathematically– statistical methods this approach represents a relatively new tool applicable in social sciences (principle of autonomous agent was described in the year 1986).Application is effected by the help of freely accessible software tool. Model’s dynamics consists in random selections of agents pair where probability tells whether they will interact or not. Interaction in this case means copying of so – called cultural characteristics.Introduced construction’s output is verification of predicament which says that taking – over postures, behaviour standards, opinions etc. in population though leads to diffusion of definite cultural pattern, nevertheless doesn’t lead to populations’ homogenization.In conclusion the deterministic character of introduced application is being specified. Also the direction of next progress at work with it this construction is being foreshadowed. Authors are aware of multiple enlargement necessity of characteristics variety and values that the characters may take. This goes hand in hand with mounting of whole process to the context with next methods dealing wiht motives forming consumer's decisions.

The present study discussed the theme of conflict in Anuradha Roy’s The Earthspinner. The novel exhibits multiple themes but the most powerful theme is ethno-cultural conflict which is depicted through various characters and their relation to each other. The study aimed at exploring the notion of ethno-cultural conflict, its causes and impact in the selected novel. Ethno- has been analyzed with the assistance of theory of conflict proposed by Max Weber. This qualitative study implied Max Weber theory of conflict. The study concludes that diverse ethno-cultural community becomes victim of conflict due to non-tolerance among people and lead to sectarian violence in the selected novel.

Full textAbstract:
With a growing recognition of the potentially catastrophic impacts of human actions on current and future generations, people around the world are urgently seeking new, sustainable ways of life for themselves and their communities. What do these calls for a sustainable future mean for our current values and ways of life, and what kind of people will we need to become? Approaches to ethical living that emphasize good character and virtue are recently resurgent, and they are especially well-suited to addressing the challenges we face in pursuing sustainability. From rethinking excessive consumption, to appropriately respecting nature, to being resilient in the face of environmental injustice, our characters will be frequently tested. The virtues of sustainability—character traits enabling us to lead sustainable, flourishing lives—will be critical to our success. This volume, divided into three parts, brings together newly commissioned essays by leading scholars from multiple disciplines—from philosophy and political science, to religious studies and psychology. The essays in the first part focus on key factors and structures that support the cultivation of the virtues of sustainability, while those in the second focus in particular on virtues embraced by various non-Western communities and cultures, and the worldviews that underlie them. Finally, the essays in the third part address further particular virtues of sustainability, including cooperativeness, patience, conscientiousness, and creativity and open-mindedness. Together, these essays provide readers with a rich understanding of the importance and diversity of the virtues of sustainability.

Full textAbstract:
Chapter 10 explores the ways in which intertexuality within and between the stages of writing, directing, and performing the film The Piano Teacher create a multi-authored text. In the absence of an ethnography of production impossible for films made in the past, the authors devised a “soft ethnography” approach focused on some key players in this “multiply authored” semiotic model (namely, the prize-winning author, director, and lead actor) to suggest the flow and feedback between these different “signatures” in the text. This soft ethnography is grounded in knowledge of the writer’s discursive history and politics, the director’s television/film sense of liberation via “obscene” cinema, and the actor’s “directing” (via her construction of character) through her performance as a developing part of her star persona. These personal/public negotiations are symptomatic of the reflexive “synthesize and extend” interdisciplinary approach of Real Sex Cinema.

Full textAbstract:
Law lay at the heart of the colonial encounter. This chapter examines the ‘deep effects’ that the colonial encounter had on law in Africa and how the very ‘litigiousness’ of Africans reflects both social change and African agency. Colonial officials used law to promote both legibility and stability of African societies. In practice, however, colonial legal systems promoted conflict by imposing rules and expectations that were not widely shared or deeply embedded in African discourses of political and social authority. The chapter explores how colonial legal pluralism led to the establishment of new formal legal institutions and how litigants used the multiple arenas created by overlapping systems of dispute settlement. Even though it was designed to respect ‘custom’, the colonial legal sphere involved the seepage of metropolitan concepts and procedures into native law and practice and often led to changes in the legal character and capacity of individuals. This enabled women, younger adults, and low-status individuals to confront men and higher status individuals even in courts designed to uphold custom.

Full textAbstract:
Dead Men Telling Tales is an account of the lasting cultural impact made by the autobiographies of Napoleonic soldiers over the course of the nineteenth century. Focussing on the nearly three hundred military memoirs published by British, French, Spanish, and Portuguese veterans of the Peninsular War (1808–1814), it charts the histories of these books over the course of a hundred years, around Europe and the Atlantic, and from writing to publication to afterlife. Drawing on extensive archival research in multiple languages, the book challenges assumptions made by historians about the reliability of these soldiers’ direct eyewitness accounts, revealing the personal and political motives of the authors and uncovering the large cast of characters, from family members to publishers, editors, and translators, involved in production behind the scenes. By including literature from Spain and Portugal, it also provides a missing link in current studies of the Revolutionary and Napoleonic Wars, showing how the genre of military memoirs developed differently in south-western Europe and led to starkly opposing national narratives of the same war. The book’s findings tell the history of a publishing phenomenon which gripped readers of all ages across the world in the nineteenth century, made significant profits for those involved, and was fundamental in defining the modern ‘soldier’s tale’.

Full textAbstract:
In contrast to other literary genres, drama has received little attention in southern studies, and women playwrights in general receive less recognition than their male counterparts. This book addresses these gaps in its examination of the work of southern women playwrights, making the argument that representations of the American South on stage are complicated by difficulties of identity, genre, and region. Success in American drama is defined as having a play staged in the capital of theatre culture, New York City, the city that might be viewed as most antithetical to the South in terms of geography and ideology. Further, women playwrights, women playwrights of color, and those who express queer identities have been vocal about persistent inequities in American theatre which have created obstacles to their success. Drama creates unique problems for playwrights through its concentrated focus on place, dialect, and character; the multiple layers of authorship; the collective reception format; and the demand for exaggeration within production. These issues, as they interact with regional conditions and perceptions, pose problems for southern women playwrights in navigating how to represent a marginalized region on the stage. Through analysis of the dramatic texts, the rhetoric of reviews of productions, as well as what the playwrights themselves have said about their plays and its productions, this book delineates these challenges and argues that playwrights confront obstacles through various conscious strategies. These approaches lead audiences to reconsider monolithic understandings of northern and southern regions and ultimately, they create new visions of the South.

AbstractThe word obesity invokes multiple connotations that contain a realm of disparate descriptions ranging from disease to disdain. There are few other human conditions that cause increased morbidity and mortality and affect millions of individuals worldwide yet is viewed by many as a character fault or moral failure. This paper explores the personal experience of obesity and how it is important to face obesity not only as a biological issue, but also a philosophical one, which has its roots in a complex phenomenon. This approach allows health professionals to propose a theoretical ethic about obesity, which goes beyond mere socio-economic-religious, and leads to an applied ethics built on the firm and solid foundations of knowledge diversity. The obese human being does not live in a world of simple events, but instead faces experiences – mystical, religious, artistic, linguistic – and, from there, configures their identity, builds personality and establishes interrelations and interdependencies. While recognizing the importance of strategies to reverse the trend of increasingly sedentary lifestyles, this paper points to the need for public health obesity reduction efforts to avoid stigmatizing people who cannot lose weight.

Full textAbstract:
AbstractThis chapter seeks to conceptualise the multi-actor character of what we refer to here as EU(ropean) foreign and security policy. It takes a holistic approach to European foreign and security policy—a policy that covers multiple areas and is carried out by a multitude of actors and institutions. While the framework builds on institutional approaches, such as the literatures on multi-level governance and Differentiated Integration (DI), it adds a new dimension by applying a somewhat broader definition of European integration—a definition that captures more than just the processes that occur within the EU. Applying a broader approach towards European integration allows us to continue to perceive the EU as central to the European integration process, while also allowing for the inclusion of other processes that in some ways, either formally or informally, are linked to the EU. We argue that such a framework better captures the dynamics of today’s increasingly complex EU(ropean) integration process, characterised by opt-outs and opt-ins, formal and informal processes, enhanced cooperation, and various forms of governance led by actors at different levels and with different types of relations to the EU. As we will show in this chapter, a more generic definition of integration helps us develop a framework that captures this complexity and sees clearly the different roles EU institutions play in the various policy areas. The intention is to present a more inclusive conceptual framework that fills two key gaps in the existing literature on European integration in this area.

Full textAbstract:
The journey appears as a regular trope in Gothic literature and cinema, prototypically in the form of the displacement of a traveller from a safe and familiar home to an enigmatic and unpredictable space. Such journeys frequently lead to the subversion of known categories and patterns of self-identity, family, nation, and empire. The films of Terence Fisher are exemplary of the representation of the Gothic journey in cinema. As Fisher’s characters make their way across the forcefully rendered psychic geographies of his films, an initial polarity between “home” and “away” progressively loses its organising power. At the same time, the foregrounding of such problems as delays, jostling, loss of luggage, and recalcitrant drivers enables the films to ground fantasies involving mortal peril and transformation in mundane aspects of the experience of travel. Fisher’s travel sequences function on multiple levels, giving expressive visual and temporal form to the metaphysical displacements that are thematically central to his work. The chapter contends that the progressive development of the theme of the journey through Fisher's work constitutes a crucial structuring of the field of the Gothic in cinema.

Full textAbstract:
This chapter introduces the Tokuyama's Theorem, first by writing the Weyl character formula and restating Schur polynomials, the values of the Whittaker function multiplied by the normalization constant. The λ-parts of Whittaker coefficients of Eisenstein series can be profitably regarded as a deformation of the numerator in the Weyl character formula. This leads to deformations of the Weyl character formula. Tokuyama gave such a deformation. It is an expression of ssubscript Greek small letter lamda(z) as a ratio of a numerator to a denominator. The denominator is a deformation of the Weyl denominator, and the numerator is a sum over Gelfand-Tsetlin patterns with top row λ + ρ.

Full textAbstract:
This chapter zeroes in on the sartorial practices of the aptly named Jack Dapper from Thomas Dekker and Thomas Middleton’s The Roaring Girl. Taking up new materialism and ecocritical theory, it demonstrates that through his sartorial extravagance, especially his interest in feathers, and his related fiscal profligacy, Jack resists restrictions upon his sexuality as well as the patriarchal imperatives of wealth accumulation. Furthermore, his superficial embodiment fosters in him, as well as the audience, an awareness that new pleasures attend upon reimagining one’s relationship to nonhuman matter. The chapter also accesses the multiple, partially realized avenues for identification and desire that a text opens up through a minor character in a play whose efforts at characterization, plot, and theme seem focused elsewhere. Such a shift in focus to what seems peripheral and precarious can form the basis of a more nuanced account of the multiple, sometimes contradictory ways that sartorial extravagance could be viewed in the period.

Syndication provided currency and connectivity on a mass scale, overcoming the limitations of print circulation. In the 1880s, newspaper syndicates began to offer an affordable means for smaller newspapers to include new stories by popular writers in their Sunday editions. Syndicated humorists, Bill Nye and M. Quad, were among the most popular features, later joined by syndicated cartoons from The Comic Sketch Club. Many Sunday papers in cities across the country began printing entire pages of humor and comics, then entire comic supplements. To compete, metropolitan Sunday papers introduced color and illustrated supplements, at first serving multiple purposes—decorative, humorous, and satirical at once. Color sections opened a special opportunity for cartoonists. Newspapers had often used recurring comic characters as mascots to personify the popularity of the paper. But the incredible popularity of The Yellow Kid, so central to the rivalry of “yellow journalism” between Hearst and Pulitzer, led other cartoonists to create recurring children's characters, giving rise to the serial comic strip. Color comic syndication began late in 1900, first with Hearst's famous cartoon characters. With syndication, even small–city papers without their own color press could include the new century's newest popular media sensation: the funny pages.

The game industry has been on exponential growth, has different businesses of varying size, ethos, scope and beyond. Success of these video-games comes from a lot of labor-intensive work by developers. Every little nuance of each character, the objects within a character’s environment must be hand-coded. Repetitive work takes up a significant part of development time, which leads to an increase in glitches and logical flaws. Artificial intelligence has been used to simulate human players in software games, provides an opportunity for game developers to create unique experiences and different outcomes for each player. Computer chess players are well-known examples, wherein modern chess programs are trained to defeat best human players. AI based algorithms that can be implemented for games, but a need for optimal solutions is on a rise. We require a comparative analysis of multiple algorithms for understanding the most efficient and ideal one. In our work, through use of a game Tic-Tac-Toe various algorithms will be carried out with its prototype compared in terms of effective rate and optimality.

<em>Abstract.</em>—It is difficult to distinguish pallid sturgeon <em>Scaphirhynchus albus</em> from the morphologically similar, congeneric and sympatric shovelnose sturgeon <em>S. platorynchus</em>. This has led some to question whether the pallid sturgeon is indeed a valid species. Another controversy is whether the two species are hybridizing. Indices, based on various morphometric and meristic characters, have been proposed to discriminate among <em>Scaphirhynchus</em> taxa, but they are cumbersome to calculate in the field. We report two mathematical indices developed via multiple regression analysis that use five morphometric ratios and two meristics (Character Index), or the five morphometric ratios alone (Morphometric Character Index) as taxon predictors. Data from a study of pallid sturgeon and shovelnose sturgeon conducted by Carlson and Pflieger (1981) were used to develop the regression models. The consistency of identifications made by the two indices was examined using Discriminant Functions Analysis (DFA) on a collection of 257 <em>Scaphirhynchus</em> specimens from throughout the pallid sturgeon range. Specimens identified via the CI and mCI as pallid sturgeon grouped distinctly from the shovelnose sturgeon cluster; specimens identified as hybrids by the two indices formed an intermediate cluster. The majority (90% and 89.7%, respectively) of the specimens identified as pallid sturgeon by the Character Index (CI) and the Morphometric Character Index (mCI) were classified as pallid sturgeon by DFA. This morphological evidence supports the current status of pallid sturgeon and shovelnose sturgeon as distinct species. Interspecific hybridization, considered by some to be a major threat to the pallid sturgeon, appears to be common. The Pallid Sturgeon Recovery Team has recommended the CI for field identifications throughout the pallid sturgeon’s range.

This chapter investigates the ways that Katherine Mansfield’s ‘Miss Brill’ is constructed through textual rhythms. Specifically, it argues that the story is distinguished by an arrhythmic duality created largely by the way that Miss Brill’s resolutely cheerful voice, which reaches us via free indirect discourse, is repeatedly undercut by a discordant undertone of melancholy. This contributes to a pattern of self-deception repeated at multiple levels of the story, culminating in a fantasy about her everyday life being part of a theatrical production. Mansfield’s mimetic use of rhythm serves a profoundly ethical purpose, using rhythm to sympathetically portray the depth of its subject’s loneliness and to expose the social structures that lead to it. The story also shows the influence on modern prose style of the relatively new field of psychology in its exploration of consciousness, emotion, and the relation between the self and the world. Beyond its ethical concerns, Mansfield’s experiment with rhythms for mimetic purposes also aims to deepen our understanding of the subtle cadences and confluences of inner and outer experience. In this, she contributes to the broader ontological and aesthetic conversations surrounding rhythm in her time.

Abstract The purpose of this chapter is to illustrate the fact that genetic variation is an important feature of virtually every human psychological trait and must be taken into account in any comprehensive explanation (theory) of human behavior. First, however, I will discuss the mistaken but widely held belief that “genetic variance” is an indicator of the biological or evolutionary unimportance of a trait. I will then turn to the role of quantitative genetic methods in modern biology. Such methods are impartial with regard to estimating genetic and environmental influences, are flexible, and provide for the simultaneous estimation of multiple influences on a character. They allow us to formally test competing theories regarding sources of human individual differences. Application of these methods across a very large number of quantitative characteristics of an equally large number of species leads to the conclusion that almost all quantitative characters are heritable (the first law of quantitative genetics). I will illustrate this truism for the major domains of normal human individual differences-mental ability, personality, psychological interests, and social attitudes. I will show that in comparison with effects in social psychology, ecology, and evolution, as well as psychological assessment and treatment, known quantitative genetic influence on human psychological traits should be considered large in magnitude. I will refute the argument that “there are no genes for behavior,” using “clockwork” genes as an example. I will also illustrate, using the example of corn oil, the fact that finding genes for a quantitative character can be very difficult.

The ideas of the Spanish-Colombian academic Jesus Martín-Barbero concerning cultural mediations and the night map will be the primary focus of this discussion as the central theoretical framework for comprehending how young people create meaning in the media, particularly worldwide animated films. Even though the theoretical framework was formed within the setting of Latin America, the notions developed by Martín-Barbero are flexible enough to be applied to any media situation. This academic discourse is enhanced by the notions of hybrid culture proposed by Néstor Garcia Canclini. These ideas provide additional foundation for the concepts and theories that are discussed in this work. Within the context of multicultural Aotearoa New Zealand, the theoretical framework was tested with young people attending English-medium schools, formerly known as mainstream schools. Participants ranged in age from six to twelve years old, and there were boys and girls from multiple ethnic origins participating. The data collection took place over the course of three years and used, among different methodologies, work groups (resembling focus groups), online surveys, and interviews. The discussion with the children aimed to discuss sixteen different Disney and Pixar films and their respective twenty-four main characters. The purpose of the conversation was to understand where children feel the characters might have come from and why they have such ideas about those characters, films’ tales, and their places. The research also focused on what characters children and young people would identify the most and the reason behind this decision. According to the research findings, one of the factors that support children in comprehending their surroundings is the cultural context of their household and how the schools they attend provide conversations around the topic of cultural identity. This research aims to show how it is possible to enhance cultural awareness in young people in a fun and light way. A diverse media setting can lead young people to demonstrate more sensitivity to the similarities and differences between two or more cultures and use this in effective communication with members of other cultural groups.

Full textAbstract:
For high-hydrogen-content fuel, the Micromix Combustion Technology has been developed as a potential low NOx emission solution for gas turbine combustors, especially for advanced gas turbines with high turbine inlet temperature. Compared with conventional lean premixed flames, multiple distributed slim and micro flames could lead to a lower NOx emission performance for shortening residence time of high temperature flue gas and generally a more uniform temperature distribution. This work aims at micromix flame characteristics of a model burner fueled with hydrogen blending with methane under atmosphere pressure conditions. The model burner assembly was designed to have six concentrically millimeter-sized premixed units around a same unit centrally. Numerical and experimental studies were conducted on mixing performance, flame stability, flame structure and CO/NOx emissions of the model burner. OH radical distribution by OH-PLIF and OH chemiluminescence (OH*) imaging were employed to analyze the turbulence-reaction interactions and characters of the reaction zone at the burner exit. Micromix flames fueled with five different hydrogen content H2-CH4 (60/40, 50/50, 40/60, 30/70, 0/100 Vol.%) were investigated, along with the effects of equivalence ratio and heat load. Results indicated that low NOx emissions of less than 10 ppm (@15% O2) below the exhaust temperature of 1920 K were obtained for all the different fuels. Combustion oscillation didn’t occur for all the conditions. It was found that at a constant flame temperature, the higher the hydrogen content of the fuel, the higher the turbulent flame speed and the weaker the flame lift effect. Combustion noise and NOx emissions also increase with increasing hydrogen content. The OH/OH* signal distribution indicated that a pure methane micromix flame showed a lifted and weaken distributed feature.

Full textAbstract:
Abstract Centrifugal pendulum vibration absorbers are a type of tuned dynamic absorber used for the attenuation of torsional vibrations in rotating and reciprocating machines. They consist of masses that are constrained to move along a specific path relative to the rotating shaft of the machine. Previous analytical studies have considered the performance of multi-absorber systems with a very specific path and of single absorber systems with general paths. In this paper we investigate the performance and dynamic stability of systems comprised of multiple, identical centrifugal pendulum vibration absorbers that have general paths. The study is carried out by considering a scaling of the system parameters based on physically realistic ranges of dimensionless parameters, which allows for application of the method of averaging. It is found that performance is limited by two distinct types of instabilities. In one of these, the systems of absorbers lose their synchronous character, while the other is a classical nonlinear jump behavior that affects all absorbers identically and leads to disastourous results. These results are used to evaluate the performance of systems with common types of absorber paths, namely circles and cycloids. The analytical results are compared against numerical simulations and good agreement is found.

Full textAbstract:
The aerodynamic interference between the blades of a bladed disk can lead to self-excited vibrations known as flutter. Flutter vibrations can reach considerable levels and are thus of special concern in the design of turbomachines. The vibrations can be saturated in so-called limit cycles by the nonlinear dissipative effects related to dry friction in mechanical joints. For a given mode family of a tuned bladed disk, the flutter stability depends on the interblade phase angle, and often multiple traveling wave forms are unstable. In spite of this, previous investigations indicated that in the steady state, friction-damped flutter vibrations of tuned bladed disks are dominated by a single traveling wave component. In contrast, we demonstrate that, in fact, multiple traveling wave components may interact in the steady state. To this end, a phenomenological model is studied, which possesses one lumped mass per sector, elastic Coulomb friction inter-sector coupling, and two unstable traveling waves forms. Depending on the location of the complex eigenvalues of the linearized system, the steady-state vibrations are shown to be dominated by either of the two unstable wave forms or exhibit considerable contributions of both. Both periodic and quasi-periodic attractor forms are computed using Fourier methods and validated with direct time integration. Moreover, the basins of attraction of the different stable limit states are analyzed in detail. Remarkably, even if a stable, periodic vibration in a certain traveling wave is attained, a sufficiently strong instantaneous perturbation of the same form can give rise to a transient ending in a limit cycle with a different traveling wave character.

Abstract During the last decades, many efforts have been invested by the scientific community in minimising exhaust emissions from aeronautical gas turbine engines. In this context, many advanced ultra-low NOx combustion concepts, such as the Lean Direct Injection treated in the present study, are being developed to abide by future regulations. Numerical simulations of these devices are usually computationally expensive since they imply a multi-scale problem. In this work, a non-reactive Large Eddy Simulation of a gaseous-fuelled, radial-swirled Lean-Direct Injection (LDI) combustor has been carried out through the OpenFOAM Computational Fluid Dynamics (CFD) code by solving the complete inlet flow path through the swirl vanes and the combustor. The geometry considered is the gaseous configuration of the CORIA LDI combustor, for which detailed measurements are available. Macroscopical analysis of the main turbulent features related to the swirling flow and the generated Central Recirculation Zone (CRZ) are well established in the literature. Nevertheless, a more in-depth characterization is still required in this area of active research since theory and experimental data are not yet able to predict which unstable mode dominates the flow. This work aims at using Large Eddy Simulation for a complete characterisation of the unsteady flow structures generated within the combustion chamber of a gaseous methane injection immersed in a strong non-reactive swirling flow field. To do so, a spectral analysis of the flow field is performed to identify the frequency, intensity and instabilities associated to the phenomena occurring at the swirler outlet region. A coherent structure known as Precessing Vortex Core (PVC) is identified both at the inner and the outer shear layers, resulting in a periodic disturbance of the pressure and velocity fields. The pressure and velocity fluctuations predicted by the CFD code are used to compute the spectral signatures through the Sound Pressure Level (SPL) amplitude at multiple locations. This allows investigating both the complex behaviour of the PVC and its associated acoustic phenomena. The acoustic characteristics computed by the numerical model are first validated qualitatively by comparing the spectrum with available experimental data. In this way, the use of dimensionless numbers to characterise the most energetic structures is coherent with the experimental observations and the characteristics of the PVC. Then, the numerical identification of the main acoustic modes in the chamber through Dynamic Mode Decomposition (DMD) allows overcoming the Fast Fourier Transform (FFT) shortcomings and better understanding the propagation of the hydrodynamic instability perturbations. This investigation on the main non-reacting swirling flow structures inside the combustor provides a suitable background for further studies on combustion instability mechanisms.

Abstract Subject North Sea oil producing well has developed sustained casing pressure in the A-annulus, resulted in well being shut-in for around 3 years. Several attempts were made to understand the source of the tubing-to-annulus communication, however remediation actions based on the conventional intervention techniques were not successful, leak location was not isolated and sustained annular pressure remained. This resulted in deferral of oil production and costs incurred due to unsuccessful intervention and remediation techniques. As the well was already equipped with the permanent fibre optic cable for the communication with the downhole pressure gauge, an alternative opportunity was taken to detect leak location by repurposing the cable for the use of Distributed Acoustic Sensing (DAS) technology along with latest pattern recognition techniques. This approach is based on decoupling of fluid movement signature from the background noise and use pattern recognition algorithms to construct fluid flow logs across entire length of the fibre, displaying character and evolution of fluid noise through depth and time. Performed acquisition program allowed to activate the leak, presence of which was clearly visible on the wellhead and A-annulus pressure data. DAS-based acoustic flow logs allowed to clearly identify the exact location of the leak points and additionally provided an understanding to the reasons of failure of remediation methods based on the interpretation of conventional tool results. Remediation strategy based on the insights provided by DAS succeeded to isolate leak points with no further pressure build-up observed in the A-annulus. As a result, operator was able to return to production the well that has been shut-in for three years. This allowed to reinstate 1mbod in production, restore well primary barriers and reduce operational spend through cancellation of further well interventions. This technology offers a new method of acoustic data processing on DAS that extracts valuable insights to identify the source of fluid flow and flow pathways, providing an ability of capturing events behind multiple casing strings.

Full textAbstract:
A three-dimensional nonlinear time-marching method and numerical analysis for aeroelastic behaviour of oscillating blade row has been presented. The approach is based on the solution of the coupled fluid-structure problem in which the aerodynamic and structural equations are integrated simultaneously in time. In this formulation of a coupled problem, the interblade phase angle at which a stability (or instability) would occur, is a part of the solution. The ideal gas flow through multiple interblade passage (with periodicity on the whole annulus) is described by the unsteady Euler equations in the form of conservative laws, which are integrated by use of the explicit monotonous second order accurate Godunov-Kolgan volume scheme and a moving hybrid H-H (or H-O) grid. The structure analysis uses the modal approach and 3D finite element model of the blade. The blade motion is assumed to be a linear combination of modes shapes with the modal coefficients depending on time. The influence of the natural frequencies on the aerodynamic coefficient and aeroelastic coupled oscillations for the Fourth Standard Configuration is shown. The stability (instability) areas for the modes are obtained. It has been shown that interaction between modes plays an important role in the aeroelastic blade response. This interaction has essentially nonlinear character and leads to blade limit cycle oscillations.

Abstract High frequency thermoacoustic instabilities are problematic for lean-premixed gas turbines. Identifying which acoustic mode is being excited is important, in that it provides insight into potential mitigation measures and mechanical stress/life. However, the frequency spacing between modes becomes quite close for high frequency instabilities in a can combustor. This makes it difficult to distinguish between the modes (e.g., the first transverse mode vs. a higher order axial/mixed mode) based upon frequency calculations alone, which inevitably have uncertainties in boundary conditions, temperature profiles, and combustion response. This paper presents a methodology to simultaneously identify the acoustic mode shapes in the axial and azimuthal directions from acoustic pressure measurements. Multiple high temperature pressure transducers, located at distinct axial and azimuthal positions, are flush mounted in the combustor wall. The measured pressure oscillations from each sensor are then used to reconstruct the pressure distributions by using a least squares method in conjunction with a solution of a three dimensional wave equation. In order to validate the methodology, finite element method (FEM) calculations with estimated post-flame temperature is used to provide the candidate frequencies and corresponding mode shapes. The results demonstrate the reconstructed mode shapes and standing/spinning character of transverse waves, as well as the associated frequencies, both of which are consistent with the FEM predictions. Nodal line location was also extracted from the experimental data during the instabilities in the pressure data.

This paper investigates reconfiguration which was induced by topology change as a typical character of metamorphic mechanisms in a way analogous to the concept of genome varation in biological study. Genome is the full complement of genetic information that an organism inherits from its parents, espercially the set of genes they carry. Genome variation is to study the change and variation of this complement with genetic information and genes connectivity and is analogous to mechanisms reconfiguration of metamorphic mechanisms. Metamorphic mechanisms with reconfigurable topology are usually changing their configurations and varying mobility in accordance with different sub-working phase functions. The built-in spatial biological modules are for the first time compiled and introduced in this paper based on metamorphic building blocks in the form of metamorphic cells and associated inside break-down parts as the metamorphic genes for metamorphic bio-modeling as genome. The gene sequencing labels the genetic structure composition principle of the metamorphic manipulators. The bio-inspired mechanism configuration evolution is further introduced in this paper motivated by biological concept to metamorphic characteristics as different sub-phase working mechanisms gradually change and develop into different forms in a particular situation and over a period of time, as an evolutionary process of topological change that takes place over several motion phases during which a taxonomic group of organisms showing the change of their physical characteristics. Moreover, the proposed genetic structure composition principle in metamorphic manipulators leads to the development of module evolution and genetic operations based on the displacement subgroup algebraic properties of the Lie group theory. The topology transformations can further be simulated for configuration evolution and depicted with the genetic growth and degeneration in the living nature. Genome sequential reconfiguration for metamorphic manipulators promises to be mapped from degenerating the source generator to multiple sub-phase configurations. Evolution design illustrations are given to demonstrate the concept and principles.

Abstract Reservoir simulation is widely applied to model and manage subsurface flow operations. However, due to the nonlinear nature of the governing equations and the multiscale character of the geological description, executing numerical simulations can be expensive and increasingly slow. In this study, we propose an innovative high-speed simulation method to build a model that is capable to predict the field's behavior. In this study, a novel AI-Physics hybrid model was proposed for reservoir simulation. Classical numerical simulation and deep learning neural networks are coupled together to create an AI-Physics hybrid reservoir simulation. As a result, a model was obtained with predictive capabilities to forecast the field's behavior. Then, we combined AI-Physics history training with blind test prediction calculation of remaining oil maps. Finally, forecast scenario definitions based on the remaining oil map were created by the AI-Physic model. The proposed high-speed simulation model can reduce the history matching and scenario assessment time by 90 to 95%. According to its capabilities, three improved forecast scenarios were created based on a predefined scenario. These improved scenarios can produce a significant million standard barrels more oil than the original development scenario within three years. This technology eliminates limitations for multiple scenario assessments. In our AI hybrid model, the power of dynamic reservoir simulation is combined with a modern machine learning approach to "Evergreen" forecasts in reservoir assets. Consequently, the simulation resulted in a sub-optimal shortcut between model updates and inconsistencies in production forecasting. Moreover, applying deep learning methods to focus on the critical reservoir properties intelligently leads to tremendous time-saving in the static model update life cycle. In fact, with this novel simulation that we implemented, the new production data could be incorporated within minutes to regenerate more reliable and up-to-date forecasts. This simulation generates ‘up-to-date remaining hydrocarbon maps interactively, so the operator can continuously optimize the infill drilling locations between Field Development Plan cycles.

Full textAbstract:
Several sedimentary exhalative (SEDEX) deposits have alkaline magmatism that is temporally and spatially associated to mineralization. This report outlines interim data from a study of potential linkages between magmatism and SEDEX mineralization in the Selwyn Basin, Yukon. This region is an ideal study site due to the close spatial and temporal relationships between SEDEX deposits and magmatism, particularly in the MacMillan Pass, where volcanic rocks have been drilled with mineralization at the Boundary deposit. Alkaline volcanic samples were analysed from the Anvil District, MacMillan Pass, Keno-Mayo and the Misty Creek Embayment in the Selwyn Basin to characterise volcanism and examine the relationship to mineralization. Textural and field relationships indicate a volatile-rich explosive eruptive volcanic system in the MacMillan Pass region in comparison to the Anvil District, which is typically effusive in nature. High proportions of calcite and ankerite in comparison to other minerals are present in the MacMillan system. Cathodoluminescence imaging reveals zoning and carbonate that displays different luminescent colours within the same sample, likely indicating multiple generations of carbonate precipitation. Barium contents are enriched in volcanic rocks throughout the Selwyn Basin, which is predominately hosted by hyalophane with rare barite and barytocalcite. Thallium is positively correlated with Ba, Rb, Cs, Mo, As, Sb and the calcite-chlorite-pyrite index and is negatively correlated with Cu. Anvil District samples display a trend towards depleted mid-ocean ridge mantle on a plot of Ce/Tl versus Th/Rb. Hydrothermal alteration has likely led to the removal of Tl from volcanic rocks in the region. Ongoing research involves: i) the analysis of Sr, Nd, Pb and Tl isotopes of volcanic samples; ii) differentiating magmatic from hydrothermal carbonate using O, C and Sr isotopes; iii) examining sources of Ba in the Selwyn Basin; iv) and constraining age relationships through U-Th-Pb geochronology.
