Abstract Natural rubber was the subject of intensive investigation with respect to its chemical reactions and the preparation of commercially useful derivatives. General reviews in this field have been written by Fisher, Schidrowitz, Jones, Sibley, Memmler, Dawson and Schidrowitz, and Farmer. Before World War II several of these reaction products, such as rubber hydrochloride (Pliofilm), isomerized rubber (Pliolite), and chlorinated rubber (Parlon), had been marketed successfully. During the past five years drastic restriction of the commercial use of natural rubber for chemical derivatives prompted the study of synthetic rubbers for this purpose. Endres recently reported on chlorinated and cyclized synthetic lubbers, with special emphasis on GR-S as the starting material. This paper deals particularly with derivatives of polyisoprene and other isoprene-containing synthetic rubbers which behave chemically very much like natural rubber because of the similarity in structure. It is shown that GR-S and other butadiene-containing synthetic rubbers, under the same conditions, are either nonreactive or behave differently. Because of its similarity to the natural rubber product, isomerized synthetic polyisoprene has been designated Pliolite S-1. Chlorinated synthetic polyisoprene is referred to as Pliochlor.

The fate of Hungarian minorities in East Central Europe has been one of the most neglected subjects in the Western scholarly world. For the past fifty years the subject—at least prior to the late 1980s—was taboo in the successor states (except Yugoslavia), while in Hungary itself relatively few scholars dared to publish anything about this issue till the early 1980s. In the West, it was just not faddish, since most East European and Russian Area studies centers at American, French and English universities tended to think of the territorial status quo as “politically correct.” The Hungarian minorities, on the other hand, were a frustrating reminder that indeed the Entente after World War I, and the Allies after World War II, made major mistakes and significantly contributed to the pain and anguish of the peoples living in this region of the “shatter zone.”

Complex socio-historical processes and turning epochs, as well as numerous segments that are an integral part of people's lives, are the subject of interdisciplinary studies. War is one of the most dramatic, most complex social phenomena. In addition to armed operations, there are a number of other dimensions related to war, starting from psychological, legal, sociological, social, economic, cultural to others. Critical and multiple perspectives contribute to the completion of images of politics, wars and their relations. The disintegrations of the ideological paradigm and the Socialist Federal Republic of Yugoslavia were accompanied by the (re)construction of new national identities, the outbreak and duration of „wars“ of different memories, the reshaping of consciousness and the re-examination of history, especially those related to World War II. The history of that war in Yugoslavia was undoubtedly the history of several wars which were stacked on top of each other. The main issue with Bosniaks in that war is a multiperspectival topic that requires a multidimensional and deideologized presentation of the position and the position of all involved actors. Numerous issues related to that war, the complex position of Bosniaks in Bosnia and Herzegovina and Sandžak, the emergence of civic responsibility, Bosniak protection of the vulnerable Serb Orthodox population, humanity and assistance, beyond post-war ideological premises and „official truths“ remained more or less marginalized, although they seek more objective and complete answers from multiple angles, for the sake of a more complete view of the past. What is called „local“ or „regional history“, as evidenced by diverse experiences, indicates the multidimensionality of the past, its features and specifics in a certain area. The Second World War in Sandžak could not be understood more objectively outside the broader Yugoslav context. This is also special for the history of Novi Pazar, the largest city in Sandžak which was the subject of many different political plans and conceptions. The history of this city has several sections. After the withdrawal of German forces from Novi Pazar, the Chetniks tried to conquer this city for three times in the fall of 1941. However, thanks to the dedicated defense and the help of Albanian armed groups from Kosovo, Bosniaks managed to defend themselves and Novi Pazar. Even in such a dramatic situation, numerous examples of humanity, solidarity and assistance of Bosniaks to the intimidated Serb urban population have been recorded. In the most difficult days of the war, when Novi Pazar was exposed to Chetnik attacks, a significant part of Bosniaks took actions to prevent anarchy, to save Serbs from terror and revenge. The task of science is to constantly discover forgotten and unknown parts of the past, to re-examine previous knowledge. Everything that happened has a whole range of perspectives. It is necessary to have a multidimensional understanding of the causes and course of events, circuits and time limits, to explain narrowed alternatives. Any reduction of historical totality to only one dimension is problematic. Every nation, every state, in a way, write their „histories“, remember different personalities, events, dates, emphasize various roles, perpetuates monuments, emphatize with different causes and consequences. Contemporary abuses of the interpretation of the war past, one-sided approaches, fierce prejucides and quasi-historical analyzes in the service of the politics damage interethic relations and lead to further growth of tensions and distancing between nations and states in their region.

Leonard Hawkes, during the past three decades one of the elder statesmen of British geology, was one of the few remaining leaders in the subject who received their training before World War I. A lifelong academic, he devoted his best years to the service of Bedford College in the University of London. A very active field-worker in early years, he became in his time a leading authority on the geology of Iceland, pursuing studies in volcanology, igneous petrology and glaciology. He served as a Secretary of the Geological Society of London for a long period at a critical stage in the history of that Society, and was later on its President. He will be remembered as one of the most amiable of characters in the post World War II scene.

Abstract It is a great pleasure and honor to have this opportunity to share with you some of my experiences in synthetic rubber over the past forty years. I am deeply appreciative of my selection as the thirty-fourth recipient of the Charles Goodyear Medal by the Rubber Division of the American Chemical Society and accept it only as a representative of my many associates at Goodyear who have participated with me in significant developments in synthetic rubber during this period. As the title of this talk indicates, we had both successes and disappointments in our endeavors to develop improved synthetic rubbers. These efforts were greatly stimulated by shortages of natural rubber which occurred in times of national emergencies such as World War II and the Korean War. When we successfully met these challenges it was fun, but to the extent that we were not able to achieve all of our objectives, we suffered a number of frustrations.

Miloje M. Vasić, "the first academically educated archaeologist in Serbia", has a strange destiny in the Serbian archaeology. On the one hand, he has been elevated to the post of the "founding father" of the discipline, with almost semidivine status and iconic importance, while on the other hand, his works have been largely unread and neglected. This paradoxical split is the consequence of the fact that Vasić has been postulated as the universal benchmark of the archaeological practice in Serbia, regardless of his interpretation of the past on the grounds of the archaeological record – the essence of archaeology. Strangely, the life and work of Vasić have not been the subject of much writing, apart from several obituaries, two short appropriate texts (Srejović, Cermanović), and rare articles in catalogues and collections dedicated to the research of Vinča (Garašanin, Srejović, Tasić, Nikolić and Vuković). The critical analysis of his whole interpretive constellation, with "The Ionian colony Vinča" being its brightest star, was limited before the World War II to the rare attempts to rectify the chronology and identify the Neolithic of the Danube valley (Fewkes, Grbić, Holste). After the war, by the middle of the 20th century, the interpretation of Vasić has been put to severe criticism of his students (Garašanin, Milojčić, Benac), which led to the significant paradigm shift, the recognition of the importance of the Balkan Neolithic, and the establishment of the culture-historical approach in the Serbian archaeology. However, from this moment on, the reception of Vasić in the Serbian archaeology has taken a strange route: Vasić as a person gains in importance, but his works are neglected, though referred to, but almost in a cultic fashion, without reading or interpreting them. Rare is a paper on the Neolithic of the Central Balkans that does not call upon the name of Vasić and his four- volume "Vinča", in which Neolithic is not mentioned at all. This paradox becomes clearer if Vasić is regarded through the prism of the problematic, but not yet challenged and universally praised values in the Serbian archaeology: material, fieldwork and authority, as opposed to interpretation, which is regarded as ephemeral. From this point of view it becomes clear how the image of Vasić grows into the icon of the Serbian archaeology, while his work slides into the domain of the oral tradition, half-truths, and apocryphal anecdotes. Considering that the majority of the Serbian archaeological community shares the belief that there is an absolute archaeological method and "pure" archaeological material, both representing "the data not burdened by theory", the field journals of Vasić and his published works become the source of the "material", while his interpretation of the past is neglected. As long as these "data" are not considered in connection to the whole opus of Vasić, the research questions and strategies that directed his work, the Serbian archaeology will be inhabited by two separate images: one – forefather and founder, the researcher of the Neolithic Vinča, "the first real Serbian archaeologist", whose face gazes at us sternly from the bronze busts and enlarged photographs, and the other – vulnerable and insulted dreamer, convinced in his philhellene delusion. Only the integration of these two images will pay due homage to Miloje M. Vasić.

This article approaches the subject of German film policy in Sweden during World War II from a new perspective. While several film scholars have mapped the connections between the German and Swedish film industries in the past, less is known about the German surveillance of Swedish film criticism, Swedish cinema audiences and Allied newsreel competitors. Drawing on previously overlooked archival material from the German film company Ufa’s Swedish subsidiary, digital newspaper archives and previous research on German film strategies abroad, this article offers new insights into the ways Ufa monitored the film market in neutral Sweden.

The article examines the reception of Giorgio Bassani’s works in Slovenia. The current state of translations of Bassani’s works into Slovene is characteristic of the availability of Slovene editions of Italian authors, which often seems desultory despite the relatively high number of literary translations from Italian published after World War II. In the past, the translations were typically published later than the original texts and without a global strategy. This situation partly persists to the present day: whilst the translations of some authors are sufficiently present, others continue to be absent, which is probably due to the limitations of the Slovene book market. As few as three of Bassani’s texts have been translated into Slovene, namely the novel Il giardino dei Finzi-Contini (1978), translated by Stabej, excerpts from the short story Una lapide in via Mazzini (1994), translated by Ožbot, and a selection of poems from In rima e senza (2008), translated by Dekleva. Il giardino dei Finzi-Contini, the only text to have been translated in an unabridged version, was also the subject of linguistic research by Miklič and Premrl. Whilst no doubt interesting for specialists, the results of their research most likely did not reach a wider public. Even though the translation of Bassani’s novel was followed by the release of the film adaptation, whilst the poetry collection received critical acclaim, Bassani remains a relatively little-known author in Slovenia to this day. Moreover, as many as thirteen years have passed since the publication of the last translation.

The Hollywood Canteen (1942–1945) was the most famous of the USO and USO-like patriotic nightclubs where civilian hostesses jitterbugged with enlisted men of the Allied Nations during World War II. It is also the subject of much U.S. national nostalgia about the “Good War” and “Greatest Generation.” Drawing from oral histories with civilian volunteers and military guests who danced at the Hollywood Canteen, this article focuses on the ways that interviewees navigated the forceful narrative terrain of national nostalgia, sometimes supporting it, sometimes pulling away from or pushing it in critical ways, and usually a little of each. This article posits a new interpretative method for analyzing struggles over “democracy” for jazz and swing studies through a focus on “torque” that brings together oral history, improvisation studies, and dance studies to bear on engaging interviewees' embodied narratives on ideologically loaded ground, improvising on the past in the present.

To reach the reader of 2018, Contemporary Albanian literature has overcome many obstacles and politics ideology. It felt violated by a certain, imposing and savage ideology. The method of socialist realism by some writers was embraced with delight and conviction, and from some others it was used for compromise to bring to light their works, which, in case of incompatibility with the relevant ideology, was banned from publishing. However, given that literature is the creation of the human spirit, it is unnatural to think that all this literature of this period has not expressed their feelings, sorrows, dreams and their love. Perhaps, we can argue with conviction, which has been a memory for the past and also a dream for the future. This literature overwhelmed the content imposed in 1945 and continued to be the most rebellious. The national liberation war was not the subject of the 1960s literature, which was more stubborn than what was written fifteen years ago, even by the same authors. Here, summed up as a great deal in the history of contemporary literature, find the first and the foremost authors of this literature, their best works, publishers, and their echoes in the language of translation. Key words: Literature, History, World War II, Writer, Contemporary, Education, Publisher.

For almost 20 years after the end of World War II, many Japanese women were challenged by a dark secondary hyper pigmentation on their faces. The causation of this condition was unknown and incurable at the time. However this symptom became curable after a number of new cosmetic allergens were discovered through patch tests and as an aftermath, various cosmetics and soaps that eliminated all these allergens were put into production to be used exclusively for these patients. An international research project conducted by seven countries was set out to find out the new allergens and discover non-allergic cosmetic materials. Due to these efforts, two disastrous cosmetic primary sensitizers were banned and this helped to decrease allergic cosmetic dermatitis. Towards the end of the 20th century, the rate of positives among cosmetic sensitizers decreased to levels of 5% - 8% and have since maintained its rates into the 21th century. Currently, metal ions such as the likes of nickel have been identified as being the most common allergens found in cosmetics and cosmetic instruments. They often produce rosacea-like facial dermatitis and therefore allergen controlled soaps and cosmetics have been proved to be useful in recovering normal skin conditions.
