Key Engineering Materials 554-557 (June 2013): 1105–15. http://dx.doi.org/10.4028/www.scientific.net/kem.554-557.1105.
Full textAbstract:
Picture frame shear tests are state of the art for determining the shear force vs. shear angle behaviour for in-plane deformation of most technical textiles, such as woven fabrics. Many publications describe this test and the used picture frames. Benchmark tests showed that the measured shearing behaviour for one sample depends on the picture frame used. The shearing rigidity of most textiles is very small compared to the in-plane tensile stiffness, so slight imperfections on the experimental setup have a significant effect on the measured results. During the picture frame test, wrinkles may form on the sample surface during the motion of the picture frame above a critical shear angle. These wrinkles can be described as local fabric buckling. If forming of wrinkles leads to a lower level of internal energy compared to a further shearing of the fabric, local wrinkles occur due to the principle of least action. Because of this effect, the measured shear force above the first formation of wrinkles is inaccurate for describing the exact shearing behaviour of textiles. Another possibility for measuring the shear force vs. shear angle behaviour is the bias-extension test. Here, higher shear angles can be achieved without the formation of wrinkles. Both methods are compared in this paper for different textile samples. The relationship of the shear angle and the applied shear force is an important mechanical value and one of the most important input parameter in numerical drape simulations. The analysis of wrinkles, which occur during textile draping, demands exact input parameters for the simulation. Most important for the drape simulation of technical high-performance textiles are accurate values for the bending and shear behaviours. This paper presents simulation results of the wrinkling during a picture frame shear test. Results show that the input parameter for the shear rigidity delivered by the picture frame shear test do not exactly reproduce the formed wrinkles and are, therefore, not suitable for an exact drape simulation. The underestimation of the shear force vs. shear angle behaviour will be shown with a finite element simulation model. The adaptation of the picture-frame and bias-extension parameters for a proper use in numerical drape simulations are examined.

Full textAbstract:
Frictional motion between contacting bodies is governed by propagating rupture fronts that are essentially earthquakes. These fronts break the contacts composing the interface separating the bodies to enable their relative motion. The most general type of frictional motion takes place when the two bodies are not identical. Within these so-called bimaterial interfaces, the onset of frictional motion is often mediated by highly localized rupture fronts, called slip pulses. Here, we show how this unique rupture mode develops, evolves, and changes the character of the interface’s behavior. Bimaterial slip pulses initiate as “subshear” cracks (slower than shear waves) that transition to developed slip pulses where normal stresses almost vanish at their leading edge. The observed slip pulses propagate solely within a narrow range of “transonic” velocities, bounded between the shear wave velocity of the softer material and a limiting velocity. We derive analytic solutions for both subshear cracks and the leading edge of slip pulses. These solutions both provide an excellent description of our experimental measurements and quantitatively explain slip pulses’ limiting velocities. We furthermore find that frictional coupling between local normal stress variations and frictional resistance actually promotes the interface separation that is critical for slip-pulse localization. These results provide a full picture of slip-pulse formation and structure that is important for our fundamental understanding of both earthquake motion and the most general types of frictional processes.

Full textAbstract:
Usual Gaussian beams are particular scalar solutions to the paraxial Helmholtz equation, which neglect the vector nature of light. In order to overcome this inconvenience, Simon et al. (J. Opt. Soc. Am. A 1986, 3, 536–540) found a paraxial solution to Maxwell’s equation in vacuum, which includes polarization in a natural way, though still preserving the spatial Gaussianity of the beams. In this regard, it seems that these solutions, known as Gauss-Maxwell beams, are particularly appropriate and a natural tool in optical problems dealing with Gaussian beams acted or manipulated by polarizers. In this work, inspired in the Bohmian picture of quantum mechanics, a hydrodynamic-type extension of such a formulation is provided and discussed, complementing the notion of electromagnetic field with that of (electromagnetic) flow or streamline. In this regard, the method proposed has the advantage that the rays obtained from it render a bona fide description of the spatial distribution of electromagnetic energy, since they are in compliance with the local space changes undergone by the time-averaged Poynting vector. This feature confers the approach a potential interest in the analysis and description of single-photon experiments, because of the direct connection between these rays and the average flow exhibited by swarms of identical photons (regardless of the particular motion, if any, that these entities might have), at least in the case of Gaussian input beams. In order to illustrate the approach, here it is applied to two common scenarios, namely the diffraction undergone by a single Gauss-Maxwell beam and the interference produced by a coherent superposition of two of such beams.

Full textAbstract:
The year of the Risorgimento, 1860, is associated with the ‘Garibaldi moment’, a time when the image of the radical revolutionary appeared to be ‘depoliticised’ in Britain. While recognising such a phenomenon, this article considers whether regional pockets escaped such a trend, analysing the case-study of Newcastle-upon-Tyne, where strong links between Garibaldi and local radicals coloured public perceptions of the Italian hero. By scrutinising the unfolding of the ‘Garibaldi moment’ in this context a complex picture emerges, showing that, far from being a unifying ‘depoliticised’ figure, Garibaldi was a source of divisions within Newcastle society. Crucial in this division was George Crawshay's challenge to the recruitment of a British Legion to follow Garibaldi. By looking at the provincial press and examining the local reception of a variety of entertainments, it is argued that, while political engagement drove the enthusiasm of radical audiences, fashionable shows–devoid of political content–could not rely on Newcastle ‘Garibaldimania’.

Research into an industrial sector reflecting principles of the emergent "network" model of production indicates that organized labour can play a positive role in post-Fordist Systems of industrial governance. Within the dynamic motion picture industry of British Columbia (B. C), organized labour was the key organizational factor in the birth and rapid expansion of the agglomeration ofsmall, specialized film production firms which has become a competitor for the coveted title of second largest film centre, after Los Angeles, in North America. In this process, B.C. film unions have become the dominant "actors " in forging collaborative relations between local production companies, between the sector and the state, and between the district and other film centers, so critical to the success of the network model.

Although it began as a local slapdash effort to advertise the independent exchanges in Chicago in 1911, Photoplay became the nation's leading movie fan magazine. At first it copied Motion Picture Story, founded earlier to publicize the films of the monopolistic Motion Picture Patents Company, in publishing literary storyized versions of film releases. Adapting the middlebrow conventions of its rival to overcome disrepute and near bankruptcy, Photoplay had already spotlighted the players in its early issues. Indeed, it established the format for publicity stories about iconic female personalities, especially those in exciting cliff-hanging serials who were idolized by lower-class female fans. It also published serialized romance fiction that featured daring, unconventional modern heroines. A magazine that stimulated readers without economic and cultural capital to daydream about glamour and buy fetishized goods, Photoplay constructed stardom as a basis of consumer capitalism.

Full textAbstract:
Market access is becoming the single most significant factor affecting collaborations between Hollywood feature film producers and their Chinese partners. The current import quota system approves only 34 films each year, which are then distributed by the state-run China Film Group, which also controls the release date for each title. The best way for a foreign filmmaker to manage these uncertainties is to fashion a co-production deal with a mainland counterpart, such as Dalian Wanda Group, which is now nearing completion of a huge studio complex in Qingdao, a project that has been greeted sceptically by industry critics. This essay assesses the ambitious logic behind this project, situating it in the broader context of the globally networked production infrastructure that has emerged over the past 20 years, one that generally favours Hollywood producers at the expense of local partners. It illustrates why the Wanda studio may in fact succeed and why foreign producers are growing ever more willing to collaborate with Chinese partners.

The problems studied in this paper are associated with a critical branching particle system in [Formula: see text], where the particle motion is described by a Lévy process. We define the intersection local time (ILT) of two independent trees, i.e. two independent particle systems, each starting from a single particle and we give sufficient conditions for its existence. The [Formula: see text]-valued density process arises as the high density limit of a "charged" particle system, where the initial positions of particles are given by a Poisson random measure. We express the self-intersection local time of this density process by means of ILTs of pairs of trees.

Full textAbstract:
In this article, an investigation on non-linear dynamical behaviours of a transmission system with a gear pair is conducted. The transmission system is described through an impact model with a possible stick between the two gears. From the theory of discontinuous dynamical systems, the motion mechanism of impacting chatter with stick is investigated. The onset and vanishing conditions for stick motions are developed, and the condition for maintaining stick motion is obtained as well. The corresponding physical interpretation is given for a better understanding of non-linear behaviours of gear transmission systems. A parameter map is presented to provide a global picture of the relationship between system parameters and corresponding motion. Grazing and stick conditions are utilized to determine the existence of periodic motions. Such periodic motions are predicted analytically through mapping structures, and the corresponding local stability and bifurcation analyses are carried out. Numerical simulations are performed to illustrate periodic motions and stick motion criteria. A better understanding of the motion mechanism between two gears may be helpful for improving the efficiency of gear transmission systems.

Abstract. In the light of recent advances in 2D turbulence, we investigate the long range predictability problem of atmospheric flows. Using 2D Euler equations, we show that the full nonlinearity acting on a large number of degrees of freedom can, paradoxically, improve the predictability of the large scale motion, giving a picture opposite to the one largely popularized by Lorenz: a small local perturbation of the atmosphere will progressively gain larger and larger scales by nonlinear interaction and will finally cause large scale change in the atmospheric flow.

Full textAbstract:
The relevance of this article is dictated by the need to study one of the main components of the Yakut geocultural landscape - the liminal road space, which is considered to be an fictional system of its own. In this regard the scientific novelty of the article is obvious: the need to view the liminal (intermediate) space as a semantic structure manifested in the constancy of images, universals that have cultural, historical, and mental commonality. The study of one of the interesting aspects of the local text, the intermediate space, has not received detailed development in Yakut science to this day. The purpose of this article is to identify the borderlines and space boundaries in particular in the context of the chronotopic system of the Yakut novel. The author emphasizes the interest in the liminal chronotope and the road as a special chronotopic complex that strengthens other spatial structures, or rather topos of the alas (villages) and cities, without which it is impossible to build a complete geopoetic picture of the Yakut world. In the context of the above theme, the image of a literary hero, whose consciousness is extremely responsive to modifications of the surrounding landscape, acquires a new semantic function. The author of the article adheres to the viewpoint that the process of evolution of the hero of the path, which is fully revealed in the space of the road, most clearly shows cultural signs of the perception of the problem of life and death which in different literary periods acquire unexpectedly interesting properties. The results of the research undertaken in this article can be used in the fictional landscape study, which is becoming the most relevant in recent times in Russian Text Linguistics.

We study the relation between two evolution pictures that are currently considered for totally constrained theories. Both descriptions are based on Rovelli’s evolving constants approach, where one identifies a (possibly local) degree of freedom of the system as an internal time. This method is well understood classically in several situations. The purpose of this paper is to further analyze this approach at the quantum level. Concretely, we will compare the (Schrödinger-like) picture where the physical states evolve in time with the (Heisenberg-like) picture in which one defines parametrized observables (or evolving constants of the motion). We will show that in the particular situations considered in this paper (the parametrized relativistic particle and a spatially flat homogeneous and isotropic spacetime coupled to a massless scalar field) both descriptions are equivalent. We will finally comment on possible issues and on the genericness of the equivalence between both pictures.

2019 is a phenomenal year for the development of the Malaysian animated film industry as it has successfully produced two superheroes animated films in total. However, the animated film industry in Malaysia is still not competitive at the international level. This can be seen from the 17 animated films that have been produced from 1998 to 2019, only two superheroes animated films managed to get the attention of the audience. This is due to the lack of knowledge of the concept and function of the hero character in animated films. Therefore, the main objective of this paper aims to demonstrate how the Hero’s Journey narrative structure can be applied in BoBoiBoy Movie 2 (2019). This research method involves the use of video analysis tools namely Kinovea and Motion Picture Analysis Worksheet to explain on how the Hero’s Journey of this film conveys the storytelling. The results of this study found that each semicircle Hero’s narrative structure has an important meaning across from one half-circle to the other half-circle. As a result, it explains the concept of peace and chaos as well as stasis and changes in the narrative structure of superhero animated films. This paper will provide information to researchers on the importance and use of the Hero’s Journey approach to analyze superhero animated films.

Full textAbstract:
AbstractThe parameter regime of strong stable density stratification and weak rotation is an important one in geophysical fluid dynamics. These conditions exist at intermediate length scales in the atmosphere and ocean (mesoscale and sub-mesoscale, respectively), and turbulence here links large-scale quasi-geostrophic motions with small-scale dissipation. While major advances in the theory of stratified turbulence have been made over the last few decades, many open questions remain, particularly about the nature of the energy cascade. Recent numerical experiments and analysis by Augier, Chomaz & Billant (J. Fluid Mech., vol. 713, 2012, pp. 86–108) present a remarkably vivid illustration of the nonlinear interactions that drive such turbulence. They consider a columnar vortex dipole, which naturally three-dimensionalizes under the influence of strong stratification. Kelvin–Helmholtz instabilities subsequently transfer energy directly to small scales, where the flow transitions into three-dimensional turbulence. This direct link between large and small scales is quite distinct from the usual picture of a turbulent cascade, in which nonlinear interactions are local in scale. But how important is this mechanism in the atmosphere and ocean?

The estimation of the impact of earthquakes on buildings and mega structures in large urban areas is of extremely importance. That is why it always gets attentions from construction planners and policy makers who are concerned about construction rules. When earthquake occurs, the vibration is transferred to sites. Although the vibration intensity is at first not too strong, the motion probably becomes stronger and lasts longer under special conditions of the local site. Two famous examples for these effects occurred in Mexico City in 1985 and in Taiwan in 1999. There are a number of approaches to this problem, such as evaluations based on seismic field observations, the microtremor method, the method using the weak motion data, the method using the strong motion data, the one-dimensional wave propagation method or the three dimensional wave propagation method with simulation etc. In this paper, we will give an overview and discuss about the advantages and the disadvantages of the methods that have been commonly applied in the world. We also present the application of these methods in studies carried out in Vietnam in general and in particular, in Hanoi city. We found that the studies for Hanoi city were mainly carried out in the western areas of Hanoi and a few positions in the urban districts. In addition, the authors only gave comments about and assessments of the shear wave velocity, and classified the ground type without a detailed map of local site effects for the entire area of Hanoi. In order to obtain a full site effects evaluation for Hanoi city, future studies should focus on the application of 1D analysis for the central area of Hanoi city and combining 1D analysis with 2D or 3D to give a better picture about the impact of local site effects. This hybrid approach is necessary in order to compare and verify the data obtained by the empirical and the analytical methods. On the other hand, many problems need to be addressed, for instance, the construction of a detailed 3D geological model for Hanoi, the calculation of the dominant periods and the amplification of the local soil conditions for the urban areas.

Full textAbstract:
The structure of labyrinth cavity flow has been experimentally investigated in a three fin axial turbine labyrinth seal (four cavities). The geometry corresponds to a generic steam turbine rotor shroud. The relative wall motion has not been modeled. The measurements were made with specially developed low-blockage pneumatic probes and extensive wall pressure mapping. Instead of the classical picture of a circumferentially uniform leakage sheet exiting from the last labyrinth clearance, entering the channel, and uniformly spreading over the downstream channel wall, the results reveal uneven flow and the existence of high circumferential velocity within the entire exit cavity. The circumferential momentum is brought into the cavity by swirling fluid from the main channel. This fluid penetrates the cavity and breaks up the leakage sheet into individual jets spaced according to the blade passages. This gives rise to strong local cross flows that may also considerably disturb the performance of a downstream blade row.

The subject of this research is the category of space – one of the intrinsic text categories that implies the meaning of location and spatial relations, and fulfills a plot-composing and semantic function. Essay is a peculiar genre, at the intersection documentary and fiction styles, which is an important factor affecting the analysis of the category of space. Examination of the category of space in essays is one of the relevant trends in linguistics. Essays of the prominent Soviet writer, photographer and journalist V. M. Peskov, which were recognized as the exemplary, serve as the material for this research. The categorical-textual approach towards studying V. M. Peskov's essays allowed determining the nuances of explication of the category of space in the genre of essay. Analysis of the specificity of the category of space in the genre of essay indicates the existence of objective and subjective space; namely the objective space holds the key place and plays a crucial role in text of the essay. In explication of the category of space are applied the direct spatial signifiers (spatial prepositions and toponyms), and indirect spatial signifiers. Texts of the essay simultaneously contain static and dynamic spaces: the author creates a static picture using existential verbs and statistical verbs of spatial location; the author describes local dynamics using the verbs of movement. The category of space is closely connected with the category of time and the category of theme; together they create a precise semantic division in accordance with the author's idea, as well help to give detailed description to the event and portray the character of the hero.

Abstract The strong ground shaking of the 23 November 1980 earthquake in southern Italy seems to have been conditioned by the dimension of the source, its focal mechanism, and by the distance from the shallow portion of the source. There was only a low, and doubtful, directivity effect. These results come from a comparison of the azimuthal distribution of the recorded peak ground horizontal accelerations with that of the total, dimensionless, radiation pattern of S waves in the horizontal plane at each site (radiation from the closest point of the fault, and appropriate azimuth and take-off angles were considered). The recorded maxima were obtained from hodogram plots of each couple of automatically digitized horizontal components in 13 stations with negligible local site effects at a distance of up to 78 km from the epicenter. The analysis indicates the strong influence of the strike-slip component on the azimuthal distribution of motion. The fault mechanism best fitting the recorded maxima is as follows: strike 318°, dip 64°, rake 317°. This picture does not change if acceleration maxima in the frequency bands 0.1 to 5 Hz, 1 to 5 Hz, or 1 to 2 Hz are used. In a segment of the southern Apennines, where the strong-motion energy radiation in the near/intermediate field of a repetitive series of shocks from the seventeenth century up to 1980 seems to be controlled by the gross features of the source, it could be useful to include radiation patterns into algorithms for regional seismic hazard calculations. Conversely, because of the fact that drawing isoseismal lines results in a smoothing of at least the very local site effects, it might be possible to infer information about the gross features of the sources of historical earthquakes from macroseismic data.

Full textAbstract:
As an orchestra or a rock star, archaeologists have their audience too. This paper wants to highlight an integrated approach between fieldwork, its account and its dissemination to the public in different ways, including social media. This potential integration has come to life in the 2011 excavation of the Roman mansio of Vignale (Italy) and it has been named “Excava(c)tion”. It doesn’t mean a new way of digging but another way of approaching the excavation, an approach integrated toward and with the public, both on site and on the social Web. “Excava(c)tion” conceives the site as a stage and digging as a performance, through a continuous dialogue between archaeologists and the public. Archaeologists share their work in the form of guided tours (live, theatrical-like performances), communicative diaries and videos (edited, motion-picture performances) and on a blog (www.uominiecoseavignale.it). They receive back comments and oral accounts from the local community about the main themes of common interest. “Excava(c)tion” means engagement both of archaeologists and the public in the pursuit of a global multivocality during archaeological excavation.

Full textAbstract:
After experiencing riots involving police and a Roma village, a community in north-eastern Slovenia hosted the million-dollar production of a major motion picture, Shanghai Gypsy (2012), which focuses on Roma and criminal justice themes. Several current Slovenian police officers played the role of police while local Roma were ‘extras’ as Roma villagers. This research explored the meaning of cooperating on production of the film for participants from two groups formerly in conflict. The current study consisted of semi-structured interviews conducted approximately 18 months after the film was produced with a sample of participants. We hypothesized that the film participants were able to interact with each other in ways that opened up new modes of communication, improved interpersonal relationships, and aided mutual understanding. Participants indicated that the film was regarded as a powerful means of generating Roma cultural awareness. Both police and Roma tended to downplay the intensity of the original conflict, yet often offered stories and anecdotes that seemed to indicate that relations between the groups had indeed improved as a result of their participation in the film.

Artificial blood pump assistance of the failing human heart can allow it to recover. Analysis of blood pump fluid flow is a useful tool for design development and thrombosis minimization. The aim of this study was to investigate fluid flow, particularly ventricular clearance rate and stagnation areas, in four different blood pump geometries and to determine the best design. The blood pumps consisted of a polyurethane ventricle, and combinations of inlet/outlet pipe angles and compression plate shapes. A video camera recorded the motion of fluid labelled with an optical tracer (Methyl Blue histological dye). A novel processing method was developed to produce colour maps of tracer concentration, experimentally calibrated. An overall picture of fluid flow in each pump geometry was generated by considering clearance curves, tracer concentration maps and inflow jet animations. Overall and local mixing coefficients are calculated for each pump. The best geometry featured straight inlet/outlet pipes and a domed compression plate. This optical tracer technique has proven convenient, economical, sensitive to low concentrations of tracer and provides instantaneous pictures of tracer distribution in a ventricle.

Films are a representation and manifestation of culture; yet, since the early days of filmmaking public debates have questioned whether “the motion picture industry was morally fit to control the content of its own products” (Robichaux). Today, the Arab world is plagued by the same dilemma. In a region where government censorship is the norm, heavy restrictions are imposed on locally produced films as a means of “safeguarding” public norms, religion and culture. Also problematic in today’s globalised world is the influx of foreign films into local markets, which not only defy public norms, but also represent cultural values and traditions that are quite alien to societies that have been inherently religious and conservative. Against this background, this article aims to analyse the role of censorship in Egypt with regard to the relationship between cinema and culture—a relationship often overlooked and perhaps intentionally ignored. In doing so, it will examine how censorship has traditionally been used as a tool to control the representation of existing social and cultural realities and to define cultural and religious norms, thus also affecting the normative context.

The Kingdom of Saudi Arabia transformed from a developing Middle Eastern nation into a regional power with ambitious projects in a variety of sectors. In this framework, the government proceeded to legalize cinemas in 2018, with an unprecedented step of issuing seven licenses for major cinema operating businesses. All of the prominent steps designed to promote the film industry align with the broader concept of expanding Saudi Arabia’s cultural and economic boundaries by adopting a path towards modernization and diversification. As the study seeks to investigate the social and economic prospects of the newly-established motion picture sector in the Kingdom of Saudi Arabia, the review is based on the recent commitments and current plans by Saudi authorities and associated organizations. From the socio-economic perspective, the decision to lift the ban on theatres is a crucial milestone, allowing the country to strengthen its entertainment sector. Despite the diversity of suggested strategic plans, the consensus of the Saudi authorities is to stimulate both local and foreign businesses seeking to open new cinemas in Riyadh, Jeddah, and other cities.

Full textAbstract:
An analysis of the degree of convergence of theoretical pictures of the dynamics of the autoionization event He(23S)-D2(v" = 0) -> [He...D2+(v')] + e is presented for a number of batches of Monte Carlo calculations differing in the number of the trajectories run. The treatment of the dynamics consists in 2D classical trajectory calculations based on static characteristics which include a quantum mechanical treatment of the perturbed D2(v" = 0) and D2+(v') vibrational motion. The vibrational populations are dynamical averages over the local widths of the He(23S)-D2(v" = 0) state with respect to autoionization to D2+(...He) in its v'th vibrational level and the Penning electron energies are related to the local differences between the energies of the corresponding perturbed D2(v" = 0)(...He*) and D2+(v')(...He) vibrational states. Special attention is paid to the connection between the requirements on the degree of convergence of the classical trajectory picture of the event and the purpose of the calculations. Information is obtained regarding a scale of the trajectory calculations required for physically sensible applications of the model to an interpretation of different type of experiments on the system: total ionization cross section measurements, Penning ionization electron spectra, subsequent 3D classical trajectory calculations of branching ratios of the products of the postionization collision process, and interpretation of electron ion coincidence measurements of the product branching ratios for individual vibrational levels of the nascent Penning ion.

Full textAbstract:
Everyday experience with centrifugal forces has always guided thinking on the close relationship between gravitational forces and accelerated systems of reference. Once spatial gravitational forces and accelerations are introduced into general relativity through a splitting of spacetime into space-plus-time associated with a family of test observers, one may further split the local rest space of those observers with respect to the direction of relative motion of a test particle world line in order to define longitudinal and transverse accelerations as well. The intrinsic covariant derivative (induced connection) along such a world line is the appropriate mathematical tool to analyze this problem, and by modifying this operator to correspond to the observer measurements, one understands more clearly the work of Abramowicz et al. who derine an "optical centrifugal force" in static axisymmetric spacetimes and attempt to generalize it and other inertial forces to arbitrary spacetimes. In a companion article the application of this framework to some familiar stationary axisymmetric spacetimes helps give a more intuitive picture of their rotational features including spin precession effects, and puts related work of de Felice and others on circular orbits in black hole spacetimes into a more general context.

In the framework of the t-Jz we discuss localized spin polarons for various original hole arrangements in different spin backgrounds. According to the so-called string picture we assume that local destruction in the magnetic structure caused by hole motion tends to localize holes and acts on them as a kind of well potential. We concentrate on the case of the hole concentration 1/8 for which stripes are experimentally observed. We explicitly take into account interaction between holes and consider several possible configurations, that represent: holes homogeneously distributed in the antiferromagnetic background, hole pairs (which correspond to spin bipolarons) homogeneously distributed in the antiferromagnetic background, hole pairs which form the stripe structure in the perfect antiferromagnetic background, and eventually holes in stripes which separate antiferromagnetic domains with alternating direction of the staggered magnetization. Spin polarons are constructed by means of some computer algebra. It turns out that lowest eigenenergy has a state that represents a single hole polaron at the anti-phase domain wall (ADW). On the other hand, the stripe phase is exposed to keen competition from holes binding in the antiferromagnetic background and the energy margin by which stripes win is small.

This essay examines the making of the independent (and no longer extant) film Once Upon a Time (1922), which was produced, directed, and written by Coconut Grove, Florida, resident Ruth Bryan Owen. As a historical and cultural prism, the film grants us a unique view of Owen as an independent filmmaker and someone who, in the late 1920s, would become the first woman elected to the US Congress from the Southern states. It also offers insights into Coconut Grove and Miami as a dynamically charged field of gender, race, and class relations during the early 1920s. For Owen, these years were filled with personal transformation as well as turmoil. South Florida was witnessing exciting changes as well as rising political tensions and strife. Proposed as a one-of-a-kind “community motion picture,” the Arabian Nights tale signaled the dawning of an active Southern Women's Club movement. In this essay, the film serves as a lens—a historical opportunity—to examine a set of social relations and the women's efforts to better their political conditions (and curb local white patriarchal corporate interests) in association with the activities and struggles of the racially segregated neighborhoods the women purported to represent.

Full textAbstract:
General environmental correlation, established for trace fossils, is hard to apply to modern sediment cores, for which environmental factors can be measured directly - at least with regard to the top layers. Reasons for this difficulty are obvious: (1) Outcrop volume is limited by the core diameter. (2) Biogenic structures are hard to see, because they have not yet been “developed” by diagenetic processes. (3) Cores are traditionally studied in vertical cuts, in which search patterns parallel to bedding plane - typical for deep-sea environment - are poorly expressed. Therefore cores from the North Atlantic were studied not only by traditional X-ray radiography (both vertical and horizontal cuts), but by computer tomography (CT), which renders series of sections parallel to the bedding plane, as well as a three-dimensional picture, without destroying the valuable core.On the Iceland-Faeroe Ridge, the distribution of ichnocoenoses appears to be largely controlled by microenvironments in connection with local channel systems and their lateral migration. In a local, ridge-parallel channel system at the southern slope, a core from the NE flank shows a vertical alternation of Zoophycos, Trichichnus, and Planolites communities correlating with fluctuations of CaCO3 and the fraction >63μm. In contrast to this, on the opposite slope, sediments are uniform and dominated by Scolicia. On the colder N slope of the ridge, topography is more uniform and the water motion is sluggish. The characteristic and dominant ichnogenus is Chondrites. On top of the ridge the sediment cover becomes very thin, contains large amounts of dropstones, but still Chondrites is dominant.

Existing accounts of Myanmar’s film industry available to English speakers are more than twenty years out of date. Opening with a brief overview of cinema in Myanmar since 2000, this article is based on a recent visit to the Myanmar Motion Picture Development Department and the Yangon Film School, on conversations with staff, students and alumnae of these institutions and of the National University of Arts and Culture, and with local independent filmmakers. The purpose of my visit was to begin the groundwork needed to answer basic questions: Who are the women making films in Myanmar today? Where are they trained? What are the conditions in which they work? What kind of films they make? How do they fund production? How do their films circulate? And finally: Is there a women’s cinema in Myanmar? What follows thus outlines the context in which women in Myanmar make films today and introduces the work of a small number of them. I conclude with reflections on three short films: A Million Threads (2006, by Thu Thu Shein), Now I am 13 (2013, by Shin Daewe), and Seeds of Sadness (2018, by Thae Zar Chi Khaing), two of which can be found online (at http://yangonfilmschool.org/___-free-yfs-film / and https://www.youtube.com/watch?v=vX0LUZQcMCQ ).

AbstractIn this article, I argue that the interest on the part of Bacon, Hill, and Warner in corpuscularian interpretations of natural phenomena and their similarity to certain views later held by Digby or Boyle offer a strong indication for the existence of an 'independent English atomistic milieu', a view that fits more closely Porter & Teich's recent model of national contexts for early modern science than Kargon's traditional picture of English atomism as a foreign import. In the course of this article, I consider Francis Bacon's anti-Aristotelian polemic in the light of his continued adherence to a conception of material form and his essentially Aristotelian metaphysics, as well as the relationship between his conception of form and his corpuscular theories of matter. This is followed by an examination of Walter Warner's natural philosophical manuscripts. Particular attention is paid to his Averroist distinction between assistant form (which has the role of an active, organizing, kinetic principle) and insistent forms (passive material formation, according to the nature of the substance and its internal combination or mixture of parts) in his treatment of the atoms of vital spirits and of the transmission of light, an idea that has interesting links to the scholastic notion of the sphaera actiuitatis. It is shown how Warner replaced the assistant form/sphere of activity with an energic principle, which he called vis and which took over many of the characteristics of the formative principles it replaced. I then compare Warner's use of vis with Nicholas Hill's, for whom it represented a hypostatic principle, i.e. an instrument of divine agency in the physical world. Such a strong view of divine causation enabled Hill to undertake a more radical critique of Aristotelian form than was available to Warner. My discussion ends with a look at Boyle's critique of the modern Aristotelian doctrine of forms, and his re-interpretation of form in terms of atomic configuration and the modifications of local motion. I end by suggesting that the 'phasing out' of Aristotelian notions of form, and their replacement with ideas of force or local motion opened the way for a similar 'phasing out' of divine causation, by making force a self-sufficient explanatory principle.

The review is dedicated to the collection “Buryatia in the days of the Great Patriotic War: 1941–45,” compiled from documents stored in the fonds of the State Archive of the Republic of Buryatia (GARB). The publication includes over 400 documents revealing various aspects of the republic inhabitants’ activities in the wartime. Documents are grouped into two sections. The first section mostly contains previously unpublished record keeping materials: decisions of local bodies of Soviet power at various levels, extracts from meetings of party committees, resolutions of rallies, reports on fulfillment and overfulfillment of state plan for supplying industrial and agricultural products, as well as appeals of workers and collective farmers to the Central Committee of the CPSU (B) and to J. V. Stalin personally. Some documents reveal the scale of uncompensated assistance provided by the residents of Buryatia, who gave money, livestock, and personal belongings to the state Defense Fund. Of interest is published correspondence with the command of partisan detachments, formed in part from residents of the republic, reports on trips to the front with labour gifts, and other documents. The second section contains sources of personal provenance: diaries and correspondence of military personnel called to the front from the republic and letters from the inhabitants of Buryatia to the army. Among the documents in this section there are excerpts from the diary of the Hero of the Soviet Union V. B. Borsoev, which is being published for the first time in this volume. The author describes the first period of World War II, the difficulties in supplying the warring army, the inability of the Red Army to fight and that of the commanders to control the troops. Front-line letters from soldiers and officers to their relatives and friends tell of the exploits and everyday life of the warring army, of the desire to defeat the enemy as quickly as possible and to return to peaceful life in the republic. The letters of the Kozulin brothers – Ivan, Alexei and Alexander, tankers who died in 1941–42, will undoubtedly attract the readers’ attention. The documents of the collection create a holistic picture of life and production activities of the population of Buryatia in the days of the war, reflect the complex and dramatic process of the regional economy restructuring for the needs of the country's defense, convey the labour heroism of industrial and agricultural workers and creative intelligentsia of the republic. The materials of the book recreate a true picture of those events, greatly enrich our knowledge on the life of the population of Buryatia in 1941–45, and, undoubtedly, serve as a valuable source for historians and for those interested in the topic.

Within the US motion picture industry, Hollywood is a (big) tree that hides the forest. Indeed, in this industry, besides this powerful and dominating industrial cluster, there are other — though minor — clusters, particularly in New York and San Francisco. The paper focuses on the latter and argues that the development of the film industry in the San Francisco Bay Area relies on specific regional assets: (1) a unique urban context and experience, (2) a unique alternative culture, and (3) a world-class technological cluster. The paper starts by briefly describing the path dependency of the film industry in the Bay Area, and how the city of San Francisco has started (in the 1980s) to implement a dedicated policy aimed at promoting the development of this industry. In this context, the paper explores the way that the San Francisco Bay Area became an attractive place for filmmakers and the fact that the 1970s marked the beginning of a new regime of film shootings. The paper then describes how, since then, the Bay Area asserted itself as a place for film production, and that has resulted in a multisite and smoothly expanding industrial cluster with a quite dynamic local labor market. Finally, the paper questions the mechanics of the film industry cluster in the Bay Area, its connections with Hollywood, and its impacts on the global influence of San Francisco.

Full textAbstract:
A large-Reynolds-number asymptotic solution of the Navier–Stokes equations is sought for the motion of an axisymmetric vortex ring of small cross-section embedded in a viscous incompressible fluid. In order to take account of the influence of elliptical deformation of the core due to the self-induced strain, the method of matched of matched asymptotic expansions is extended to a higher order in a small parameter ε = (v/Γ)1/2, where v is the kinematic viscosity of fluid and Γ is the circulation. Alternatively, ε is regarded as a measure of the ratio of the core radius to the ring radius, and our scheme is applicable also to the steady inviscid dynamics.We establish a general formula for the translation speed of the ring valid up to third order in ε. This is a natural extension of Fraenkel–Saffman's first-order formula, and reduces, if specialized to a particular distribution of vorticity in an inviscid fluid, to Dyson's third-order formula. Moreover, it is demonstrated, for a ring starting from an infinitely thin circular loop of radius R0, that viscosity acts, at third order, to expand the circles of stagnation points of radii Rs(t) and R˜s(t) relative to the laboratory frame and a comoving frame respectively, and that of peak vorticity of radius R˜p(t) as Rs ≈ R0 + [2 log(4R0/√vt) + 1.4743424] vt/R0, R˜s ≈ R0 + 2.5902739 vt/R0, and Rp ≈ R0 + 4.5902739 vt/R0. The growth of the radial centroid of vorticity, linear in time, is also deduced. The results are compatible with the experimental results of Sallet & Widmayer (1974) and Weigand & Gharib (1997).The procedure of pursuing the higher-order asymptotics provides a clear picture of the dynamics of a curved vortex tube; a vortex ring may be locally regarded as a line of dipoles along the core centreline, with their axes in the propagating direction, subjected to the self-induced flow field. The strength of the dipole depends not only on the curvature but also on the location of the core centre, and therefore should be specified at the initial instant. This specification removes an indeterminacy of the first-order theory. We derive a new asymptotic development of the Biot-Savart law for an arbitrary distribution of vorticity, which makes the non-local induction velocity from the dipoles calculable at third order.

ABSTRACT Myxobacteria build their species-specific fruiting bodies by cell movement and then differentiate spores in specific places within that multicellular structure. New steps in the developmental aggregation of Myxococcus xanthus were discovered through a frame-by-frame analysis of a motion picture. The formation and fate of 18 aggregates were captured in the time-lapse movie. Still photographs of 600 other aggregates were also analyzed. M. xanthus has two engines that propel the gliding of its rod-shaped cells: slime-secreting jets at the rear and retractile pili at the front. The earliest aggregates are stationary masses of cells that look like three-dimensional traffic jams. We propose a model in which both engines stall as the cells' forward progress is blocked by other cells in the traffic jam. We also propose that these blockades are eventually circumvented by the cell's capacity to turn, which is facilitated by the push of slime secretion at the rear of each cell and by the flexibility of the myxobacterial cell wall. Turning by many cells would transform a traffic jam into an elliptical mound, in which the cells are streaming in closed orbits. Pairs of adjacent mounds are observed to coalesce into single larger mounds, probably reflecting the fusion of orbits in the adjacent mounds. Although fruiting bodies are relatively large structures that contain 105 cells, no long-range interactions between cells were evident. For aggregation, M. xanthus appears to use local interactions between its cells.

Full textAbstract:
Large-eddy and interface simulation using an interface tracking-based multi-fluid flow solver is conducted to investigate the breaking of steep water waves on a beach of constant bed slope. The present investigation focuses mainly on the ‘weak plunger’ breaking wave type and provides a detailed analysis of the two-way interaction between the mean fluid flow and the sub-modal motions, encompassing wave dynamics and turbulence. The flow is analysed from two points of views: mean to sub-modal exchange, and wave to turbulence interaction within the sub-modal range. Wave growth and propagation are due to energy transfer from the mean flow to the waves, and transport of mean momentum by these waves. The vigorous downwelling–upwelling patterns developing at the head and tail of each breaker are shown to generate both negative- and positive-signed energy exchange contributions in the thin sublayer underneath the water surface. The details of these exchange mechanisms are thoroughly discussed in this paper, together with the interplay between three-dimensional small-scale breaking associated with turbulence and the dominant two-dimensional wave motion. A conditional zonal analysis is proposed for the first time to understand the transient mechanisms of turbulent kinetic energy production, decay, diffusion and transport and their dependence and/or impact on surface wrinkling over the entire breaking process. The simulations provide a thorough picture of air–liquid coherent structures that develop over the breaking process, and link them to the transient mechanisms responsible for their local incidence.

Full textAbstract:
Wetting and dewetting are both fundamental modes of motion of liquids on solid surfaces. They are critically important for processes in biology, chemistry, and engineering, such as drying, coating, and lubrication. However, recent progress in wetting, which has led to new fields such as superhydrophobicity and liquid marbles, has not been matched by dewetting. A significant problem has been the inability to study the model system of a uniform film dewetting from a nonwetting surface to a single macroscopic droplet—a barrier that does not exist for the reverse wetting process of a droplet spreading into a film. We report the dewetting of a dielectrophoresis-induced film into a single equilibrium droplet. The emergent picture of the full dewetting dynamics is of an initial regime, where a liquid rim recedes at constant speed and constant dynamic contact angle, followed by a relatively short exponential relaxation of a spherical cap shape. This sharply contrasts with the reverse wetting process, where a spreading droplet follows a smooth sequence of spherical cap shapes. Complementary numerical simulations and a hydrodynamic model reveal a local dewetting mechanism driven by the equilibrium contact angle, where contact line slip dominates the dewetting dynamics. Our conclusions can be used to understand a wide variety of processes involving liquid dewetting, such as drop rebound, condensation, and evaporation. In overcoming the barrier to studying single film-to-droplet dewetting, our results provide new approaches to fluid manipulation and uses of dewetting, such as inducing films of prescribed initial shapes and slip-controlled liquid retraction.

Full textAbstract:
Next to his signature, Viennese painter Johann Ignaz Cimbal often added a peculiar sign in his frescoes and oils. It is a combination of letters, appearing in a different form in each of the studied cases (Zalaegerszeg, Oberlaa, Zwettl, Peremarton, Tornyiszentmiklós, Nagykároly [ Carei]), which – and the poor state of the works – make the identification of the letters difficult. In most cases the sign reads VSG, so it is not the initials of the painter.In some Cimbal works the three letters also appear with iconographic meaning. On the picture of the King Saint Stephen side altar in the parish church of Tornyiszentmiklós the letters shining in the halo around the Holy Cross were identified as VSG earlier and decoded as “Vera Sacra Crux”. However, it is more likely that this abbreviation hides the same meaning as the monograms next to Cimbal’s signatures.Guidance to the elucidation of the monogram was provided by the ceiling fresco in the southern vestry-room of Székesfehérvár cathedral. The clearly readable VSG abbreviation appears in the corners of the triangle symbolizing the Holy Trinity, which leaves no doubt that it is in connection of the Holy Trinity. The most obvious explanation is the letters being the initials of the German words for the three divine entities, Vater, Sohn and [Heiliger] Geist.The attribution of the picture (Maria Immaculata) on the high altar of the parish church of Sárospatak to Cimbal was suggested on the basis of this motif, here in three corners of a triangular aureole around the Ark of Covenant. The attribution is also confirmed by style critical analyses. (Analogous are Cimbal’s Immaculata figures in Zalaeregszeg, Tornyiszentmiklós and Székesfehérvár.)The abbreviation alluding to the Holy Trinity, which is perfectly embedded in the iconographic fabric of some paintings, was also used by Cimbal independently of the theme, attached to his name. Inserting a sign referring to the Holy Trinity above his name must have been a religious gesture. Having completed a picture, the painter crossed himself, as it were, offering his work to God. He sealed his offering with the mysterious sign of God “in the name of the Father, the Son and the Holy Ghost”. (A similar religious gesture must underlie the signature 70 of an early Cimbal work, the Saint Anne altar picture in Vienna’s Barmherzigenkirche. The abbreviation “Zimbal i. VR” is traditionally interpreted as “In veneratione” with the explanation that the painter made the picture as a votive offering.) Cimbal always created a new composition out of the three letters, so it cannot have been his aim to make a recognizable constant “trade-mark”. (For this purpose he used his name with the customary addition “invenit et pinxit”.) The linking of the three letters is not just a customary formal solution as in monograms, but it has a meaning: it symbolizes the unity of the three divine persons, just as the circle in the triangle in Székesfehérvár.An extremely expressive iconographic solution needs special mention, applied almost to each of his depictions of the Holy Trinity in Hungary. It is the sceptre held by the three coeternal persons (hence it has extreme length). As it occurs so frequently, it cannot be part of an occasional client’s wish but much rather it is the painter’s invention. Perhaps a comprehensive examination of the entire oeuvre will discover further examples in support of the author’s hypothesis that the Holy Trinity was a particularly favourite theme of Cimbal. It was again his personal devotion that led him to use the Holy Trinity monogram.The motivation behind commissions for religious art works in the period was first of all the client’s personal religiosity. The religious motifs of the artists can usually only be inferred from indirect data and in connection with few works. One such sign is that for the duration of painting the frescoes Franz Anton Maulbertsch joined the Scapular Confraternity of Székesfehérvár, while the group portrait on the organ loft of Sümeg permits the assumption that he took part in the devotions of the Angelic Society founded by bishop Márton Padányi Biró. His pupil Johannes Pöckel who settled in Sümeg was a member of the local Confraternity of the Cord.

Full textAbstract:
Next to his signature, Viennese painter Johann Ignaz Cimbal often added a peculiar sign in his frescoes and oils. It is a combination of letters, appearing in a different form in each of the studied cases (Zalaegerszeg, Oberlaa, Zwettl, Peremarton, Tornyiszentmiklós, Nagykároly [ Carei]), which – and the poor state of the works – make the identification of the letters difficult. In most cases the sign reads VSG, so it is not the initials of the painter.In some Cimbal works the three letters also appear with iconographic meaning. On the picture of the King Saint Stephen side altar in the parish church of Tornyiszentmiklós the letters shining in the halo around the Holy Cross were identified as VSG earlier and decoded as “Vera Sacra Crux”. However, it is more likely that this abbreviation hides the same meaning as the monograms next to Cimbal’s signatures.Guidance to the elucidation of the monogram was provided by the ceiling fresco in the southern vestry-room of Székesfehérvár cathedral. The clearly readable VSG abbreviation appears in the corners of the triangle symbolizing the Holy Trinity, which leaves no doubt that it is in connection of the Holy Trinity. The most obvious explanation is the letters being the initials of the German words for the three divine entities, Vater, Sohn and [Heiliger] Geist.The attribution of the picture (Maria Immaculata) on the high altar of the parish church of Sárospatak to Cimbal was suggested on the basis of this motif, here in three corners of a triangular aureole around the Ark of Covenant. The attribution is also confirmed by style critical analyses. (Analogous are Cimbal’s Immaculata figures in Zalaeregszeg, Tornyiszentmiklós and Székesfehérvár.)The abbreviation alluding to the Holy Trinity, which is perfectly embedded in the iconographic fabric of some paintings, was also used by Cimbal independently of the theme, attached to his name. Inserting a sign referring to the Holy Trinity above his name must have been a religious gesture. Having completed a picture, the painter crossed himself, as it were, offering his work to God. He sealed his offering with the mysterious sign of God “in the name of the Father, the Son and the Holy Ghost”. (A similar religious gesture must underlie the signature 70 of an early Cimbal work, the Saint Anne altar picture in Vienna’s Barmherzigenkirche. The abbreviation “Zimbal i. VR” is traditionally interpreted as “In veneratione” with the explanation that the painter made the picture as a votive offering.) Cimbal always created a new composition out of the three letters, so it cannot have been his aim to make a recognizable constant “trade-mark”. (For this purpose he used his name with the customary addition “invenit et pinxit”.) The linking of the three letters is not just a customary formal solution as in monograms, but it has a meaning: it symbolizes the unity of the three divine persons, just as the circle in the triangle in Székesfehérvár.An extremely expressive iconographic solution needs special mention, applied almost to each of his depictions of the Holy Trinity in Hungary. It is the sceptre held by the three coeternal persons (hence it has extreme length). As it occurs so frequently, it cannot be part of an occasional client’s wish but much rather it is the painter’s invention. Perhaps a comprehensive examination of the entire oeuvre will discover further examples in support of the author’s hypothesis that the Holy Trinity was a particularly favourite theme of Cimbal. It was again his personal devotion that led him to use the Holy Trinity monogram.The motivation behind commissions for religious art works in the period was first of all the client’s personal religiosity. The religious motifs of the artists can usually only be inferred from indirect data and in connection with few works. One such sign is that for the duration of painting the frescoes Franz Anton Maulbertsch joined the Scapular Confraternity of Székesfehérvár, while the group portrait on the organ loft of Sümeg permits the assumption that he took part in the devotions of the Angelic Society founded by bishop Márton Padányi Biró. His pupil Johannes Pöckel who settled in Sümeg was a member of the local Confraternity of the Cord. Unfortunately, no information to this effect is known about Cimbal.His signature and Holy Trinity monogram testify that not only the client but also the painter offered his work to God.

Full textAbstract:
Studies of monolingual narrative production have revealed interacting paths in the development of coherence and cohesion across languages but less is known about bilingual narratives, where a gap may exist between socio-cognitive and linguistic abilities. The present longitudinal study explores the relations between measures of coherence and cohesion in the picture-based oral narratives elicited from 23 sequential bilinguals at two times — 2nd and 4th years of exposure to Hebrew as L2 (ages 6 and 8, respectively), compared to those produced by age-matched Hebrew speaking monolinguals. Measures of coherence included reference to story components, and to four types of causal relations: psychological, motivational, enabling and physical. These analyses served as a basis to explore cohesion in terms of (1) inter-clausal connectivity, and (2) the linguistic encoding of the causal chain, which in this context demanded reference to a complex motion event. We found that reference to narrative components and causal relations improved with age in both L1 and L2, but were largely delayed among bilinguals at age 6, particularly regarding the most complex scenes. While coherence measures reached to a parallel level among the 8 year-old children, measures of cohesion showed a different path of development in L1 and L2. Thus, the constraints imposed by language use in organizing the discourse resulted in a poorer connectivity between the clauses, and in less accurate lexico-grammatical encoding of the events in the bilingual narratives. The study underscores the mutual attraction between local and global principles of narrative construction, which may become dissociated in a bilingual situation, and pinpoints to vulnerable domains of L2 discourse-embedded acquisition.

NOT CHANGING LOOKS. PRESENTATION OF CRUELTY AND EVIL IN THE FILMS OF ANDRZEJ WAJDAAmong Andrzej Wajda’s legacy, the image of the totalitarian regime and its repercussions for people, countries, and humanity holds a significant place. Films of Andrzej Wajda, who was a liaison officer in the anti-Hitler Polish underground, are a kind of chronicle of the survivors of twentieth century. The article is dedicated to study the various forms of evil and its effects on real people. The study is applicable for our time because the world again deals with the recidivism of evil which the Soviet government spread in its own country and beyond its own borders. In the USRR, the perception of Andrzej Wajda’s films was dependent on the political play in action: when the relations between two countries were friendly, he received awards, however after the Solidarity was established, no one ever mentioned Wajda. The epic work Danton, about the French revolution, made in France during times difficult for Poland because of the martial law imposed on Poland, reveals the effects of revolution that paradoxically destroyed its most dedicated revolutionists, including Danton. Wajda’s refusal to American producers to direct a motion picture based on a screen play of Aleksander Slozenicyn had se-rious reasons, primarily commitment to his homeland. He made up for the missed opportunity to show Stalin’s evil empire when he shot the film Katyń. This word echoes deep tragedy in the heart of every Pole and the director succeeded in portraying the cruelty of mechanism of punishment in totalitarian USRR. The second most important aspect was the discovery of the lies of this regime, which tried to place the responsibility for the execution of Polish officers on the Nazis. After a premiere of Katyń in Ukraine, Andrzej Wajda was awarded the medal of Jaroslaw Madry. The article also includes the theme of influence of Fyodor Dostoyevsky’s novels on Andrzej Wajda’s work — the director not only used Dostoyevsky’s work for his filmmaking and staging, but as well he was inspired by Dostoyevsky’s deep analysis of dangerous social phenomena and the courage in discovering the evil. In Wajda’s films, which belongs to the so-called “cinema of moral unrest”, the tragic fate of a talented journalist Jerzy Michalowski, the hero of film Bez znieczulenia who personalizes the characteristics of a professional and a good man, simply horrifies. In his last film Powidoki, the director masterfully shows circles of hell survived by avant-garde artist Wladyslaw Strzeminski, the lecturer of Fine Arts Academy. All the films mentioned above are deemed necessary warning for future generations, they cannot put up with the aggression — on a political and private levels. Wajda’s lessons are universal, timeless, and everla-sting, like an eternal battle of good against evil.

Full textAbstract:
The greatest loss caused by the insurgency in Narathiwat province which is in the south of Thailand is the lives of the orphans whose parents or beloved ones have been deprived among conflicts and violence. Even though the affected people have received different aids, such cases are not as important as the situation faced by the orphans. After the losses, no one truly pays attention to the extent to which the southern crisis affects these unfortunate children. Even in time of peace, the children who will become adults in future have to face and suffers from severe social biases at home and elsewhere. They also have to face violence and the lack of safety in their lives. This is a result of the fire of vengeance between local people and the government’s suppression which is a game of those villains in power. The orphans will have to sustain their lives alone despite some aids from the government and private sectors. In order to create social awareness of the orphans’ daily lives in Narathiwat province, which affects their psychological status, education, and security of individual, social, and country’s levels, the awareness is raised through video art creation. Video art is a form of art which can reflects the way of lives of those who suffer from losses by presenting the stories of those who have lost, especially in terms of mental status after the loss. Video arts also present views and cultures of the locals with motion pictures, picture placement, and actions and contemporary artistic framework to convey the important message to the society so that people will understand the reality. Video arts are produced based on the researcher’s viewpoints and attitudes gained from the five senses – vision, hearing, smell, taste and touch. Video art is also a type of media that fully responds to human’s imaginations.

Zemletriaseniia Severnoi Evrazii [Earthquakes in Northern Eurasia], no. 22 (November 12, 2019): 329–42. http://dx.doi.org/10.35540/1818-6254.2019.22.30.
Full textAbstract:
The February 28, 2013 earthquake (MwGCMT=6.8), which occurred on the southeast coast of Kamchatka, is discussed. The instrumental hypocenter location reported by the KB GS RAS is φ=50.67N, λ=157.77E, h=61 km. Three magnitudes were obtained: local magnitude ML=6.9, code-wave magnitude Mc=6.6, mo-ment magnitude Mw=6.7. The focal mechanisms of the February 28, 2013 earthquake and its aftershocks with ML≥6 correspond to the tectonic conditions of subhorizontal compression in the NW–SE direction. For most of these mechanisms, the shallow plane falls under Kamchatka, which corresponds to the geometry of the subduction zone. The small-focus aftershocks cloud of the February 28, 2013 earthquake has the 5828 km size and is extended in the north-east – south-west direction. The aftershock process has the three-phase character and can be considered as a stream of seismic events decreasing in time with three successive stages with different attenuation modes. The change in attenuation modes is associated with strong after-shocks. The duration of the decaying aftershock process is ~ 100 days. The February 28, 2013 earthquake was felt with intensity ranged from 2 to 5–6 on the MSK-64 scale in 33 localities (Δ=81–493 km). The mac-roseismic impact area was about 56∙103 km2. The mainshock and its four strong aftershocks have a similar picture of macroseismic manifestations: the macroseismic effect is larger on the east coast of Kamchatka; the strongest shakes has been observed in Severo-Kurilsk (Paramushir Island). The elongation of the isoseist along the Kamchatka eastern coast has been observed, which is typical for Kamchatka earthquakes. The strong ground motions from the February 28, 2008 earthquake has been recorded using the Kamchatka net-work of digital accelerographs. The level of peak amplitudes for this earthquake is consistent with average trends in the Kamchatka region. Attenuation parameters are typical for Kamchatka. The shallow layer of the seismic focal zone of the Kuriles and South Kamchatka, in which the February 28, 2013 earthquake was recorded, is one of the most active seismic areas in the North-West Pacific. Earthquakes with M>8 were re-peatedly occurred here, causing a tsunami and intensity of shakes up to 9 on the MSK-64 scale in the south of Kamchatka.

The study of the current state of biobibliography of Buryatia, presented in the library web envi-ronment, was the purpose of this article. The author used methods of comparative analysis, monitoring of the web environment, bibliographic. The research results should include a representation of the forms of bio-bibliographic information that exists in the library web environment. The comparative characteristics of Internet resources contributes to the discovery of specifics in the creation of infor-mation products by libraries of various types and types. Links to websites identified in the process of studying the electronic environment can be used as a guide to the bio-bibliographic resources of the libraries of the republic. The article reflects bio-bibliographic information on library websites, which is publicly available. Traditional bio-bibliographic indexes are reviewed – digital copies and electronic versions of printed publications, original bibliographic products, complex electronic resources, databases that combine elements of bio-bibliographic, reference, full-text materials. Data on information products of scientific and public libraries was revealed: the National Library of the Republic of Buryatia, universities, the Buryat Scientific Center of the Siberian Branch of the Russian Academy of Sciences (BSC SB RAS), the Republican Library for Children and Youth, centralized library systems of the city of Ulan-Ude and the republic. Bibliographic information in the form of indexes, dictionaries (“Who's Who”), databases (“Teachers' Works”, etc.) has a special place on the websites of scientific libraries of universities: Buryat State University, East Siberian State University of Technology and Management, Buryat State Agricultural Academy, East-Siberian State Institute of Culture. The website of the Central Scientific Library of the BSC SB RAS reflects the “Works of the BSC SB RAS employees” in the same heading, information on memorial libraries of prominent scientists in the field of physical and mathematical sciences, literary criticism, art history, ethnography, oriental studies. The website of the National Library of the Republic of Buryatia provides the most valuable edi-tions of local history topics: electronic versions of printed publications, reference and bibliographic databases, and electronic collections dedicated to prominent figures of the republic. Republican library for children and youth, Central City Library named after I.K. Kalashnikov, the centralized library sys-tems of Ulan-Ude and the republic are created and distributed in the Internet space, mainly bio-bibliographic information of recommendatory nature, in order to popularize the personality of the writer, public figure, war hero, historical character. Conclusions are made about the diversity of forms of bio-bibliographic information in the library web environment and, at the same time, the need to achieve common organizational and methodologi-cal approaches of libraries to create bio-bibliography in the republic and its presentation in the Internet space. The general picture of the state of biobibliography considered in the article, the mentioned names of famous figures of the republic give a curtailed knowledge about of the development of science, culture and other areas of public life in the past and in modern times.

"Magnetosphere dynamics during the 14 November 2012 storm inferred from TWINS, AMPERE, Van Allen Probes, and BATS-R-US–CRCM."

Abstract. During the 14 November 2012 geomagnetic storm, the Van Allen Probes spacecraft observed a number of sharp decreases (“dropouts”) in particle fluxes for ions and electrons of different energies. In this paper, we investigate the global magnetosphere dynamics and magnetosphere–ionosphere (M–I) coupling during the dropout events using multipoint measurements by Van Allen Probes, TWINS, and AMPERE together with the output of the two-way coupled global BATS-R-US–CRCM model. We find different behavior for two pairs of dropouts. For one pair, the same pattern was repeated: (1) weak nightside Region 1 and 2 Birkeland currents before and during the dropout; (2) intensification of Region 2 currents after the dropout; and (3) a particle injection detected by TWINS after the dropout. The model predicted similar behavior of Birkeland currents. TWINS low-altitude emissions demonstrated high variability during these intervals, indicating high geomagnetic activity in the near-Earth tail region. For the second pair of dropouts, the structure of both Birkeland currents and ENA emissions was relatively stable. The model also showed quasi-stationary behavior of Birkeland currents and simulated ENA emissions with gradual ring current buildup. We confirm that the first pair of dropouts was caused by large-scale motions of the OCB (open–closed boundary) during substorm activity. We show the new result that this OCB motion was associated with global changes in Birkeland (M–I coupling) currents and strong modulation of low-altitude ion precipitation. The second pair of dropouts is the result of smaller OCB disturbances not related to magnetospheric substorms. The local observations of the first pair of dropouts result from a global magnetospheric reconfiguration, which is manifested by ion injections and enhanced ion precipitation detected by TWINS and changes in the structure of Birkeland currents detected by AMPERE. This study demonstrates that multipoint measurements along with the global model results enable the reconstruction of a more complete system-level picture of the dropout events and provides insight into M–I coupling aspects that have not previously been investigated.
