Unsteady viscous flows and Stokes's first problem are examined. Three problems are considered: unsteady Couette flow, unsteady Poiseuille flow, and unsteady boundary layer flow. The relationship between these three fundamental unsteady flows and Stokes' first problem is illustrated. Scaling principles are used to deduce the short time and long time characteristics of these three problems. Asymptotic analysis is used to obtain exact short and long time characteristics and to show the relationship of each problem to Stokes's first problem for short times. Finally, compact robust models are developed for all values of time using the Churchill-Usagi asymptotic correlation method to combine the short and long time characteristics.

The characteristics of flocs aggregated in flocculation have been paid more and more attention for a long time. In this paper, a new classification and analyses method dealing with the flocs is developed. The flocs formed after flocculation is divided into four kinds, including the left primary particles, linear flocs with all component particles in a line, planar flocs with all component particles on a plane and volumetric flocs with all component particles in a three-dimensional space. By analyzing the formation approaches of different kind of flocs regardless of the floc breakage, the number of every kind of floc is analyzed to be related with the suspension concentration mathematically. After comparing the different items in the models describing the relationship of floc number and concentration, a series of simplified expressions are presented. Lastly, a mathematical equation relating the measurable suspension viscosity with the numbers of different flocs is obtained.

A previous report gave the results of an experimental study of the relationship between short-time and long-time creep limits of a number of carbon steels. Certain conclusions were drawn which it was realized were not necessarily applicable to other types of steel. Similar experimental work has since been carried out on six carbon molybdenum steels, and the results obtained indicate similar limitations in the applicability of short-time creep limits to estimation of design stresses for long-time service, as were disclosed by the prior tests on carbon steels. There is not, at first sight, any reason why short-time and long-time creep limits should correlate, since with most engineering materials metallurgical changes occur during prolonged heating.

This article highlights different ways of metaphorical use in language and shows its potential in attracting the readers' attention. Language as a biological being lives its own life witnessing never-ending changes: falling outs and newly built elements. We enrich our language not only by new elements but also by new styles and reusing of existing sources. One of these ways which makes language more alive and active is metaphor. Metaphor nowadays is found in all the fields of life, education, medicine, policy and everyday life. Metaphor, in fact, reflects the relationship of language to culture and the world of ideas. Language, on the one hand, is a repository of culture; the traditions, proverbs, and knowledge of our ancestors. On the other hand, language is the mirror of the world of ideas. People reflect their new ideas in using language in new ways, even such devices as paintings and riddles. Metaphor has many shapes and is found in spoken and written language, graphics, cartoon or caricature, riddles, jokes and paintings to express novel shades of meanings, e.g., metaphor in newspaper photos, magazines or even in advertisements attracts the attention of readers and are memorized for a long time. Metaphoric use is also a way of enjoying the readers. It is used for both real and logical aims such as; warnings, advises, or invitations ...etc

This study is to find out the relationship of characters to illustrations in a collection of 9short stories from NadiraKarya Leila S. Chudori. In the collection, there are four short stories that contain illustrations of the main characters namely "Melukis Langit”, "Tasbih", "Sebilah Pisau", and "At Pedder Bay". The method used in this research is descriptive qualitative method by using Charles Sanders Pierce's Semiotic Theory which includes sign and object. The study of characterization or characterization is done in two methods namely direct (telling) and indirect (showing). The results of  this study indicate that out of the 4 short stories analyzed only 3 short stories that have character relationships with illustrations, namely the short story "Melukis Langit", "Tasbih" and "Sebilah Pisau". Short story of "Melukis Langit" depicts Nadira's character who is strong against her father's behavior since the death of his mother. The short story illustration shows Nadira crying in the bathroom to vent her sadness. Short story "Tasbih" describes Mr. X with a mysterious character illustrated by showing Mr. X's face full of mystery while the short story "Sebilah Pisau" tells Kris who is Nadira's secret admirer. Kris's character is displayed with illustrations illustrating the event when Nadira was surprised to see Kris's table filled with Nadira's picture. Short story "At Pedder Bay" tells Nadira's old friend Marc who is also an admirer of Nadira for a long time. The main character, Marc in this short story is not illustrated in the illustration. The short story shows a background, namely the lake and the figure of the woman sitting pensively.

The article, for the first time, exami­nes the work of the master of the 18th century Jean-Honoré Fragonard (1732—1806) within the context of the theatre culture of that time. Being a student of François Boucher (1703—1770), who was working as a theater decorator for a long time, Fra­gonard from his youth had the opportunity to join the world of theater. The painter’s passion for the stage greatly influenced the thema­tic and figu­rative composition of his works. Early histo­rical pain­tings of Fragonard, such as “Jeroboam Sacrifi­cing to Idols” (1752, School of Fine Arts, Paris), were crea­ted under the influence of Baroque thea­ter and decorative art and opera productions. Undoubtedly, Fragonard’s familiarity with theatre was promoted by his long stay in Italy, where the famous families of theater decorators Bibiena and Galliari was wor­king at that time. The article pays special attention to the process of planning and execution of the painting “The High Priest Coresus Sacrificing Himself to Save Callirhoe” (1765, Louvre), made not without regard to the opera “Callirhoe”, popular in Paris in the 18th century. It was theater that inspired the master to create his famous costume series of “Fantasy Portraits”, one of which depicted Marie-Madeleine Guimard (1743—1816), who not only had posed for the artist, but also ordered him to design her own mansion conceived as a temple of Terpsichore, the Muse of dance. In addition, Fragonard was the author of several panoramic genre paintings conveying the atmosphere of the then popular street theater. Works of this brilliant master exem­plify the relationship of arts that determined the nature of the cultural environment of that era and requires constant attention from modern researchers.

Abstract Abstract SCI-7 The current paradigm suggests that Langerhans cell histiocytosis (LCH) results from an accumulation of epidermal dendritic cells also called Langerhans cells. This concept is based on phenotypic and ultrastructural observations showing that LCH lesions are infiltrated by CD1a+langerin+ cells, two features thought to be restricted to epidermal Langerhans cells. It has been difficult, however, to understand how Langerhans cells, which are normally restricted to stratified epithelia, could give rise to such a multifocal disorder. LCH research has been handicapped by the inability to develop reliable animal models and by the fact that for a long time very few markers were available to determine the origin and stage of differentiation of histiocytes, now renamed macrophage/dendritic cell lineages. This presentation will discuss recent progress in our understanding of the regulation of the Langerhans cell, macrophage, and dendritic cell lineages and discuss the relationship of these lineages with the LCH cell. Disclosures: No relevant conflicts of interest to declare.

This concluding chapter looks at human rights co-ordination within the UN system. For a long time, human rights in the United Nations tended to be treated as a special domain, one which might be of growing importance, but which did not necessarily need to be a consistent focus of the entire UN machinery. The importance of co-ordination and coherence for human rights promotion, however, has steadily become clearer, as the perception has grown that the human rights ‘issue area’ cannot be successfully dealt with in a vacuum or in isolation. The focus here, accordingly, is on the relationship of human rights to various relevant parts of the UN system—‘inter-regime’ co-ordination—rather than on co-ordination among human rights activities undertaken by the various members of the UN family of institutions—‘intra-regime’ co-ordination. It is the former aspect of co-ordination that has proved to be most problematic and had achieved the least progress until the recent period.

The bimodal character of stocks is demonstrated when they are classified according to their style. Stocks are often assigned, on the basis of some valuation parameter, uniquely as either value or growth even though, over time, changes in a stock’s-growth probability should trace the evolution of the corporate life cycle. This study is concerned with investigating the relationship of that probability to market cycles. Two hundred and eighty eight stocks from the ASEAN are tracked over an eight-year period. The percentages of those, on a monthly basis, that are in the top quintile of EPS growth, as well as the top quintile of major value (current) styles are calculated. Using multidimensional scaling, the study concludes that the degree of differentiation between growth and value rises as the market declines, and that styles are purer at the bottom than at the top of the market cycle.
