There are distinctive and characteristic genomic modifications in primordial germ cells that distinguish the germ cell lineage from somatic cells. These modifications include, genome-wide demethylation, erasure of allele-specific methylation associated with imprinted genes, and the re-activation of the X chromosome. The allele-specific differential methylation is involved in regulating the monoallelic expression, and thus the gene dosage, of imprinted genes, which underlies functional differences between parental genomes. However, when the imprints are erased in the germ line, the parental genomes acquire an equivalent epigenetic and functional state. Therefore, one of the reasons why primordial germ cells are unique is because this is the only time in mammals when the distinction between parental genomes ceases to exist. To test how the potentially imprint-free primordial germ cell nuclei affect embryonic development, we transplanted them into enucleated oocytes. Here we show that the reconstituted oocyte developed to day 9.5 of gestation, consistently as a small embryo and a characteristic abnormal placenta. The embryo proper also did not progress much further even when the inner cell mass was ‘rescued’ from the abnormal placenta by transfer into a tetraploid host blastocyst. We found that development of the experimental conceptus was affected, at least in part, by a lack of gametic imprints, as judged by DNA methylation and expression analysis of several imprinted genes. The evidence suggests that gametic imprints are essential for normal development, and that they can neither be initiated nor erased in mature oocytes; these properties are unique to the developing germ line.

Mammalian parthenotes cannot develop normally to term. Mouse parthenogenetic embryos die by Day 10 of gestation. On the other hand, viable parthenogenetic chimeras were produced by normal host embryos, although parthenogenetic cells were observed in a limited number of tissues and organs and, even in these instances, their contribution was substantially reduced. This can be explained by the aberrant expressions of imprinted genes in parthenogenetic cells. In female mice, erasure of imprints occurs around the time that primordial germ cells enter the gonad, and establishment of imprints occurs in the postnatal growth phase of oogenesis. In this study, we investigated whether aberrant imprints in parthenogenetic embryonic stem (PgES) cells can be erased through the germline. Diploid parthenogenetic embryos were produced by activation of (CBA × C57BL/6-EGFP) F1 mouse superovulated unfertilized oocytes by exposure to Sr2+ and cytochalasin B. Ten parthenogenetic blastocysts were plated and three PgES cell lines were isolated. Chimeras were made by injecting 10–15 PgES cells into ICR(CD-1) mouse blastocysts. Chimeras and chimeric tissues were detected by fluorescent microscopy. In all, 173 chimeric blastocysts were transferred to 9 recipient females, and 101 live pups containing 9 female and 21 male chimeras were born. No significant growth retardation was apparent in PgES chimeras, irrespective of their degree of chimerism. In 5 male chimeras killed at 1 day postpartum (dpp), PgES cells showed a restricted tissue contribution. The contribution to lung, liver, and intestine was considerably lower than in the other tissues such as brain, heart, spleen, and kidney. PgES derived or host embryo derived non-growing oocytes were isolated from dissociated ovaries of female chimeras at 1 dpp under fluorescent microscopy. Methylation imprints in non-growing oocytes were analyzed for maternally methylated imprinted genes Peg1, Snrpn, and Igf2r by the combined bisulfite restriction analysis (COBRA). In normal oocytes, imprints are expected to be erased and these genes are unmethylated at this stage. We observed that these genes were unmethylated in both PgES derived and host embryo derived non-growing oocytes. These results suggest that aberrant imprints in PgES cells can also be erased normally through the germline.

Abstract
Background: Even though water is regarded as something long understood and explained by conventional science – many open-minded researchers know that it still hides many mysteries (water clusters, coherent domains, so-called memory, etc.). Many of these mysteries come to fore in ultra-high dilution (UHD) experiments and practices, where usually not even one molecule of the originating substances is left. Mostly, they can be tackled only by using the droplet evaporation method (DEM).1
Aim: One of the hypotheses of water memory suggests that through UHD (dilutions, shaking) the field of a substance is stably impressed into water. If this is true than we should be able to imprint also a field itself - not originating from a certain substance, but from other sources. Such imprint should be revealed by an appropriate research method.
Method: The DEM consists of monitoring dried water drops by dark field microscopy. It was discovered in the previous century by Ruth Kübler, a German artist, and further developed by Bernd-Helmut Kröplin, Minnie Hein, Berthold Heusel M. A. and Georg Schröcker. It has also been used to research the still controversial special characteristics of ultra-high diluted aqueous solutions.2 It has been proved capable of demonstrating differences in subtle influences of an UHD (around 10-47 M, practically “pure†water) of As2O3 on common wheat seeds. This method is therefore, capable of transferring certain, not yet fully understood or generally accepted subtle physical characteristicsof the solution to the remnant patterns after drop evaporation.3, 4
We used DEM to evaluate experiments on impressing the subtle field of five bioenergy healers and two so called “informed†objects (a glass and an “energy†card) into mineral or spring water with well-known characteristics. In all these experiments we also used control water that was of the same origin, but placed in a separate room. The DEM images were analyzed by special computer programs and statistically evaluated. No mother tincture of any kind was used.
Results: The results demonstrate that even such subtle fields can leave stable and reproducible imprints in water - made visually accessible by the remnant patterns after drop evaporation. The irradiated water samples were statistically different from the control. This difference can usually be observed even by a naked eye.
Conclusion
These results have several implications. They confirm as follows:
a) water memory – the main background of UHD effects,
b) the possibility to imprint the fields into water,
c) the existence of subtle fields not yet generally recognized by physical community and
d) the capability of DEM to express the imprints.

“Corazón de la oscuridad” [Heart of Darkness] takes up a title by Joseph Conrad; here darkness equals evil. It admits the polysemy of the word evil, which bounces back on its opposite good. In ancient philosophy, God was the Highest good, Christian religion left an imprint of this faith even in individuals who do not consider themselves religious. Even if we are not aware of it, many of the imprints that we carry inside ourselves (in the other self) move the affects. We must discover the manifested motive; then we discover the twinning character of the sacred, explicit in the patron saint festivities. Ancient rituals, however terrible we may judge them, lead to sociability as a symbol, and can become a manifestation of good and justice.

Abstract We study the capabilities of present and future radio very long baseline interferometry arrays to distinguish black holes from horizonless spacetimes. We consider an example of a horizonless spacetime, obtained by overspinning a regular black hole. Its image is distinct from the image of a Kerr spacetime due to a second set of photon rings interior to the shadow. These photon rings cannot be directly resolved by present and even next-generation Event Horizon Telescope arrays, but instead imprint themselves in horizon-scale images as excess central brightness relative to that of a black hole. We demonstrate that future arrays can decrease the upper bound on the central brightness depression by a factor of 10 and thereby detect such indirect imprints from non-Kerr spacetimes in reconstructed images.

ABSTRACT We consider the possibility that dark energy and baryons might scatter off each other. The type of interaction we consider leads to a pure momentum exchange, and does not affect the background evolution of the expansion history. We parametrize this interaction in an effective way at the level of Boltzmann equations. We compute the effect of dark energy-baryon scattering on cosmological observables, focusing on the cosmic microwave background (CMB) temperature anisotropy power spectrum and the matter power spectrum. Surprisingly, we find that even huge dark energy-baryon cross-sections $\sigma _{xb} \sim {\cal O}({\rm b})$, which are generically excluded by non-cosmological probes such as collider searches or precision gravity tests, only leave an insignificant imprint on the observables considered. In the case of the CMB temperature power spectrum, the only imprint consists in a sub-per cent enhancement or depletion of power (depending whether or not the dark energy equation of state lies above or below −1) at very low multipoles, which is thus swamped by cosmic variance. These effects are explained in terms of differences in how gravitational potentials decay in the presence of a dark energy-baryon scattering, which ultimately lead to an increase or decrease in the late-time integrated Sachs–Wolfe power. Even smaller related effects are imprinted on the matter power spectrum. The imprints on the CMB are not expected to be degenerate with the effects due to altering the dark energy sound speed. We conclude that, while strongly appealing, the prospects for a direct detection of dark energy through cosmology do not seem feasible when considering realistic dark energy-baryon cross-sections. As a caveat, our results hold to linear order in perturbation theory.

"After the disaster: Bony fish remains (mostly otoliths) from the K/Pg boundary section at Stevns Klint, Denmark, reveal consistency with teleost faunas from later Danian and Selandian strata." Bulletin of the Geological Society of Denmark 65 (17 agosto 2017): 59–74. http://dx.doi.org/10.37570/bgsd-2017-65-05.
Testo completoAbstract (sommario):
This is the first study of bony fish remains across the K/Pg boundary section at Stevns Klint, Denmark. The studied specimens comprise one partly preserved articulated skeleton, a few isolated bones, and casts from several otolith imprints and voids. As otoliths are aragonitic, the remains are all dissolved. The imprints of the otoliths originate from the uppermost Maastrichtian Højerup Member or ‘Grey Chalk’, and the bone fragments and the partial skeleton were obtained from the Fiskeler Member directly above the K/Pg boundary. Further otolith imprints originated from the basal Danian Cerithium Limestone Member, which directly overlies the Fiskeler Member. Six otolith-based taxa were identified from the uppermost Maastrichtian and three from the basal Danian. One of the species found in the uppermost Maastrichtian persisted into Danian times (Polymixia? harderi), a second represents a common genus in both Maastrichtian and Danian but cannot be identified to the species level (Centroberyx sp.), and a third taxon is an unidentifiable dynematichthyid, which, however, certainly does not belong to any of the known Danian dinematichthyid species. The species recognised in the basal Danian all persisted well into later Danian times or even the Selandian, showing a remarkable consistency of the early Paleocene bony fish fauna. We find no indication of phased extinction in the aftermath of the K/Pg boundary event in the data recovered from the Danian.

Abstract Detection of specific chromosomal abnormalities is essential in the diagnosis of several lympholiferative disorders. However, conventional cytogenetic studies are not frequently carried out from biopsies as it is in bone marrow (BM) specimens. On the contrary, FISH is usually performed on paraffin embedded tissue, an alternative with potential technical nuances both in its application and its interpretation. In our experience, FISH on tissue imprints is the ideal alternative to overcome these problems. In the present study, 46 tissue imprints and 17 BM smears from 43 patients with lymphomas were selected to investigate the presence of t(14;18)(q32;q21), t(11;14)(q13;q32), t(8;14)(q24;q32) and t(3;var)(q27;var). Representativity of the samples was assured prior to FISH by rapid May-Grümwald staining (Diff-Quick, QCA, Spain). Twenty imprints from reactive palatine tonsils and adenoids were used as negative controls. FISH was performed with specific dual-color dual-fusion FISH (D-FISH) probes for the first 3 translocations and a dual-color break-apart FISH probe for t(3;var)(q27;var) following the instructions of the probes supplier (Vysis, Inc). All except one sample (a BM smear stored at room temperature over 9 years), rendered satisfactory FISH hybridizations. In any case, all 43 patients could be successfully studied by FISH (the case referred above in which FISH failed in a first attempt was successfully analyzed using a different sample). The results supported the suspected diagnosis of follicular lymphoma in 22 patients, mantle cell lymphoma in 12 patients, large B-cell lymphoma in 5 patients, marginal zone lymphoma in 2 patients and B chronic lymphocytic leukemia in 2 patients. In one case, the observation of t(11;14) by FISH allowed to reclassify the case from follicular to mantle cell lymphoma and also to demonstrate clonal evolution by studying sequential tissue imprints stored for more than 6 years. Negative results also aided in the assignment of patients to proper diagnostic categories. FISH performed on tissue imprints and BM smears constitutes an optimal strategy for retrospective and prospective investigation of chromosomal abnormalities in lymphomas. Tissue imprints and BM smears conventionally stored at room temperature even for long periods of time can be safely used and sent by ordinary mail without special considerations for this purpose. Based on our experience we recommend to perform and routinely store tissue imprints whenever fresh tissue is available.

Extemporary (EXT) analysis is unavoidable in establishing the tumor diagnosis, operability and the extent of the operation. Alternative approach is cytologic analysis which, because of its simple methodology, provides results even faster. In this paper, the results of cytologic imprints (CI) and EXT finding were compared with definite histopathologic diagnosis (HDP) to determine the value of both methods. A total of 109 samples obtained during 55 thoracotomies were analyzed. Eighty eight specimens were analyzed simultaneously by CI Method and in frozen sections. Twenty one sample was analyzed only by cytologic methods and the results of standard CI were compared with definite HDP. After being processed for EXT diagnosis, intraoperative specimens were imprinted on glass slides, air-dried and stained by May-Gr?nwald-Giemsa Method. In cytologic analysis there were no false negative results, but there were 7 false positives. The overall diagnostic accuracy was 93.6%, sensitivity and negative predictive value was 100%, specificity was 91.1% and positive predictive value was 81.8%. Diagnostic accuracy of frozen sections was 98.8% also without false negatives and with one false positive finding with sensitivity and negative predictive value of 100%, specificity of 98.4% and positive predictive value of 95%. These results corresponded to the results of other studies and confirmed the efficacy of CI method, which could be used either simultaneously with EXT diagnosis as a complementary or as an alternative method in the hospitals where EXT analysis is not used. However, imprint cytology demands an experienced cytologist and could be used only in hospitals with well organized cytologic service.

ABSTRACTThis article analyzes the effects of firms’ founding ownership in shaping their corporate social responsibility (CSR) performance in China. Drawing on a nationwide survey of 1,037 representative manufacturing firms in 12 cities, we specify the imprinting effects of firms’ founding ownership on labor and environmental protections, two important CSR practices. Our results show that state-owned enterprises (SOEs) founded during the state socialist period, regardless of their restructuring experience in the market reform era, continued to implement pro-labor practices. Moreover, even the SOEs founded in the market reform era provided better labor protection than non-SOEs founded during the same time. In contrast, the founding imprints of environmentalism in the reform era for non-SOEs, especially thede novoprivate firms, explain why they spent more than SOEs in environmental protection. We extend the organizational imprinting theory by highlighting the importance of firms’ founding ownership imprints and in shaping their current CSR performance.

This book deals with the problem of human reason and thinking from a somewhat unexpected angle. Its main idea is that both are the product of evolution, and therefore they bear the imprint of their history, and they are mostly reduced to them, although they are not entirely limited to them. This means that they are by no means universal, on the contrary, they are conditioned by their very formation and the circumstances within which they developed and which literally created them as we know them. In practical terms, this suggests that they are aimed at solving the problems and the type that faced our species during its rather long formation, and they are not able to answer any other questions, no matter how much effort we put into it. Even what seems to us an exceptional attribute of modernity or rationality, such as science or politics, fits within the framework of what is available to us, as well as what we are able to formulate and articulate in principle. That is, our intelligence is purely animal and contextual, it never goes beyond the limits set for it, despite the fact that we see it differently. In this regard, questions of their definition, origin, history and current state are considered, and among other things, alternative options that are potentially possible in the field of intelligence, both on Earth and in general, are studied.
The text consists of five chapters, a preface and an afterword, is provided with illustrative examples and is aimed at the widest possible adult readership, who likes to think and who is not afraid of debunking some of the ingrained myths that accompany our lives.

Testo completoAbstract (sommario):
Hidden forces—memories of past poor or hurtful relationships—drive repressed feelings and emotions that are often outside our awareness. Though we want to love and be loved, to nurture and be nurtured, those forces can wreak havoc and cause relationship sabotage, destroying couples and even whole families. The scenario is so common, explains therapist Matta, that often people get divorced without even fully understanding why, or what is was that came between them. In many cases, what it was were the lingering but unconscious memories of lessons learned as far back as childhood. These lessons may have no true bearing or justification in the current relationship, yet they can strongly affect it, fueling marital games, extra-marital affairs, addictions, poor parenting practices and a host of other harmful actions. Matta argues that we can learn to recognize these imprints and move past them to build or keep rewarding relationships. His book makes us aware, and gives us the tools to break the cycle.

Germany's constitutional charter, adopted in 1949, is entitled the Basic Law. The Basic Law had evolved into one of the world's most admired constitutions, even rivalling that of the United States in influence and prestige around the world. So when the day of unity finally arrived in 1990, East and West Germany merged under the imprint of the Basic Law itself. Today, in both structure and substance, although frequently amended, it remains the constitutional text of reunited Germany. This chapter discusses the constitutive assembly of Germany, constituent power and reunification, general features of the Basic Law, supremacy of the constitution, constitutional structure, amending process, the Federal Constitutional Court, problems of constitutional interpretation, conception of the constitution, negative and positive rights, horizontality of rights, sources of interpretation, approaches to interpretation, the civil law tradition, and style of judicial decision-making.

Having mapped out in the previous chapter, New Labour’s often contradictory and even ‘politically-convenient’ understanding of globalisation, chapter 3 offers analysis of three key areas of domestic policy that Gordon Brown would later transpose to the realm of international development: (i) macroeconomic policy, (ii) business, and (iii) welfare. Since, according to Brown at least, globalisation had resulted in a blurring of the previously distinct spheres of domestic and foreign policy, it made sense for those strategies and policy decisions designed for consumption at home to be transposed abroad. The focus of this chapter is the design of these three areas of domestic policy; the unmistakeable imprint of Brown in these areas and their place in building of New Labour’s political economy. Strikingly, Brown’s hand in these policies and the themes that underpinned them would again reappear in the international development policies explored in much greater detail later in the book.

Cyrus the Great was a transformational figure: an exceptional leader, general, and visionary. He was also the founder of the Achaemenid Persian Empire, which dominated the world stage from the Mediterranean to the Indus during the sixth through fourth centuries BCE. When Cyrus took the royal title “King of the World” in 539 BCE, it was closer to a literal reality than for any ruler before him in history. Cyrus the Great thus was an object of fascination even in antiquity, well-regarded among several peoples in almost every accounting of his life. This book treats the stories of Cyrus’ birth, conquests, and reign through multiple perspectives, grounded in analysis of ancient sources from the Persians, Elamites, Babylonians, Judeans, and Greeks. Cyrus the Great remains a worthy object of attention for the imprint he left on world history, anywhere the ancient Achaemenid Empire touched in antiquity, and its legacy thereafter.

Testo completoAbstract (sommario):
Working from a speculative, more-than-human ontological position, Inefficient Mapping: A Protocol for Attuning to Phenomena presents a new, experimental cartographic practice and non-representational methodological protocol that attunes to the subaltern genealogies of sites and places, proposing a wayfaring practice for traversing the land founded on an ethics of care. As a methodological protocol, inefficient mapping inscribes the histories and politics of a place by gesturally marking affective and relational imprints of colonisation, industrialisation, appropriation, histories, futures, exclusions, privileges, neglect, survival, and persistence. Inefficient Mapping details a research experiment and is designed to be taken out on mapping expeditions to be referred to, consulted with, and experimented with by those who are familiar or new to mapping. The inefficient mapping protocol described in this book is informed by feminist speculative and immanent theories, including posthuman theories, critical-cultural theories, Indigenous and critical place inquiry, as well as the works of Karen Barad, Erin Manning, Jane Bennett, Maria Puig de la Bellacassa, Elizabeth Povinelli, and Eve Tuck and Marcia McKenzie, which frame how inefficient mapping attunes to the matter, tenses, and ontologies of phenomena and how the interweaving agglomerations of theory, critique, and practice can remain embedded in experimental methodologies.

In the year 1800 the United States was a fledgling nation. By the time the century ended we had expanded westward exponentially, stamped our imprint as the major power in the Western hemisphere, revolutionized our economy from agriculture to manufacturing, and suffered the schism of a civil war that nearly brought the nation as conceived by our forefathers to an end. To help students better understand the cataclysmic changes of this century, this unique resource offers detailed description and expert analysis of the most important 19th-century events in America: the Louisiana Purchase, the War of 1812, the Monroe Doctrine, Jacksonian Democracy, Abolition, the war with Mexico, the Civil War, the Industrial Revolution, the closing of the frontier, and the Spanish-American War. Each of these events is dealt with in a separate chapter. A factual introductory essay provides clear, concise information in chronological order. The interpretive essay, written in a widely appealing style by a recognized authority, then places each event in a broader context and explores the short-term and far-reaching ramifications of the event. A selected bibliography that follows identifies the most important and recent scholarship about the event. A full-page photo or illustration of each event portrays a visual component to the narrative. The volume contains three useful appendices: a glossary of names, events, and terms; a timeline of important events in 19th-century American history; and a list of 19th-century U.S. presidents, vice presidents, and secretaries of state. This work is an ideal addition to the high school, community college, and undergraduate reference shelf, as well as excellent supplementary reading in social studies and American history courses.

Testo completoAbstract (sommario):
The Art of Fact in the Digital Age is a showcase of the most powerful and moving journalism of the past 25 years. Selections include stories originally published in established bastions of literary journalism (The New York Times, The Atlantic and The New Yorker), as well as those from specialized and online publications (Runner’s World, The Atavist). It features writers of extraordinary style (including Carina del Valle Schorske, Brian Phillips, and Jia Tolentino), as well as those who have profoundly influenced public discourse on the 21st century’s most urgent issues: Mitchell S. Jackson, Clint Smith, and Ta-Nehisi Coates on race; Susan Dominus and Luke Mogelson on migration; and Kathryn Schulz and David Wallace-Wells on environmental threats. It even includes one story that expanded literary journalism’s repertoire into audio (This American Life). This collection, assembled for students, scholars, and practitioners alike, also charts the evolution of digital longform journalism through its greatest achievements, from transitioning readers to screens to the integration of multimedia with words in service of meaning. The art of fact in the 21st century opened new ranges of expression to address such issues, while uniquely bearing the imprint of their generation’s digital cultures and technologies. Although many forces compete for attention in the digital age, story triumphs. The works in this anthology show us why.

Testo completoAbstract (sommario):
No candidate for President of the United States was ever elected or rejected because of a song, but since 1800 the campaign song appeared constantly (until 1964) amidst the paraphernalia of the electoral process. These songs, usually set to the common tunes of their day, were printed and distributed in the form of books or pamphlets named songsters. Until now, few serious studies of the American presidential campaign songster have been written. This vital work by William Miles brings bibliographic control to the study of the American presidential campaign by focusing on each campaign's songsters from 1840 to 1964. The book is arranged chronologically according to election campaigns, and within each campaign by winner, loser, and third party candidates. Each entry contains information on authors, lyricists, or composers as determined from song title-pages, the volume itself, or other sources. Complete titles and imprint data follow within each entry, along with descriptive notes and references to libraries holding copies of the volume cited. Appendixes include a campaign song discography and a checklist of secondary sources.Songs, Odes, Glees, and Balladsshould prove to be of great value to music librarians, curators of special collections, political scientists with an interest in national election campaigns, historians, and collectors of and dealers in political Americana.

From the Strand up to Oxford Street, the West End came to stand for sensation and vulgarity but also the promotion of high culture. The reader will explore the growth of theatres, opera houses, galleries, restaurants, department stores, casinos, exhibition centres, night clubs, street life, and the sex industry. The West End produced shows and fashions whose impact rippled outwards around the globe. During the nineteenth century, a neighbourhood that serviced the needs of the aristocracy was opened up to a wider public whilst retaining the imprint of luxury and prestige. The book tells the story of the great artists, actors, and entrepreneurs who made the West End: figures such as Gilbert and Sullivan, the playwright Dion Boucicault, the music hall artiste Jenny Hill, and the American retail genius Harry Gordon Selfridge who wanted to create the best shop in the world. We encounter the origins of the modern star system and celebrity culture. The book moves from the creation of Regent Street to the glory days of the Edwardian period when the West End was the heart of empire and the entertainment industry..

AbstractIn 1946, the first Palestinian book fair took place at the Arab Orthodox Union Club in Jerusalem. What lay behind this event was a process that paralleled the political life revolving around the formation of local nationalism, a complex process of cultural and literary development within the Arab Nahda (‘Awakening’ or Renaissance) movement in which the Palestinians left their imprint through the press, literature, translation and other cultural fields. This chapter discusses the cultural environment of Khalīl Baydas and Iskandar al-Khūrī al-BeitJālī who initiated the modern Palestinian Arabic novel, both publishing in 1920. It addresses the Palestinian Nahda and the Russian educational enterprise as the formative context of these two authors and propose that Khalīl Baydas should be recognised as the architect of Palestinian literary realism.

Trauma-themed military documentaries served a variety of promotional purposes—many of them strictly corporate—during and after World War II. These experiments in institutional advertising, with their emphasis on the therapeutic dimensions of extensive militarization, were hardly limited to the postwar period. In a fundamental sense, they originated with the military’s wartime efforts to contain widespread concerns regarding war trauma—efforts that met the militant tone of certain orientation films with a more measured, even somber reflection on the psychic costs of combat.

The introduction considers some of the consequential intersections between Freudian psychoanalysis, military psychiatry, and documentary film in a period that predated the codification of war trauma as PTSD. At stake in its reevaluation of wartime and postwar military media is a broader understanding of how war trauma and psychotherapy were articulated in and through documentary and realist film. Situated at the intersection of trauma studies and documentary studies, the introduction considers some of the historically specific debates about, aspirations for, and uses of documentary as a vehicle for honoring, monitoring, understanding, publicizing, and even “working through” war trauma, while occasionally conceding trauma’s contradictory and intractable character.

This chapter examines the musical substyles that enhance storytelling in the narrative arts collectively known as katarimono, particularly the medieval musical narrative genres of Heike recitation and kōwaka danced ballads, but also in later Tokugawa-period genres. Both narrate to musical accompaniment the battles between the Heike and Genji warrior clans in the twelfth century. The chapter discusses styles related to Heike recitation that have persisted over time and that have been adapted to different performance genres, and it explores the proposition that the formulae and musical substyles employed for specific kinds of narrative content, in this case content related to war, enhanced the memorability of the narratives and their impact on listeners. Ultimately, the chapter traces the persistence of these two broad styles of musical expression even as they change over time and across different genres to show how this practice of katarimono shaped and kept the cultural memory of the wars alive in popular memory.

This chapter examines how Albatross Press revived its publishing business after World War II. In peacetime, John Holroyd-Reece envisioned an Albatross with more international ties than ever to liberate a continent held captive by nationalism. In this new Europe, Albatross had forged partnerships with one publisher in each market, an array of joint imprints bearing the Albatross logo. Yet even Albatross's expanded ties could not protect it from the “Kriegspsychose [war psychosis] and prejudice against German firms” that Holroyd-Reece had predicted. This sentiment reinforced the British book trade's longstanding resentment toward Albatross and Bernhard Tauchnitz. This chapter considers Max Christian Wegner's efforts to put Tauchnitz back on the map and Holroyd-Reece's attempt to reclaim Tauchnitz and bring Albatross back into Germany along with it.

Modern Africa’s first formalized liberal democracies came with various legislatures left behind by the colonialists. Yet soon after independence, most new African leaders enforced their own imprints on the states, restructuring, even abolishing, the various institutions they controlled, suggesting them to be colonial burdens inappropriate for African conditions. One-party systems of government became the norm. ‘Democracy in Africa’ discusses the wave of democratization beginning in the 1990s and the introduction of multiparty elections. The quality of Africa’s democracies is, however, uneven; despite political changes, the entrenchment of democratic values remains shallow and compromised. However, some progress has been made: around one-quarter of African states are now ‘free’.

This chapter delves into population genetics with a human focus and explores the assumptions of the Hardy—Weinberg equilibrium model. It reviews the many different types of evolutionary change which can operate in order to shape the genetic structure of a population and the imprints these leave at the level of the genome. It also features long-term studies of bacterial populations presented as a method to explore evolution experimentally. The chapter describes how transmission of alleles and genotypes within a population can be assessed, even when the individual matings cannot be monitored. It defines non-random mating as the main process that affects genotype frequencies without affecting allele frequencies directly, which can result in population stratification.

Testo completoAbstract (sommario):
Many present landscape elements in western and central Europe are to a large extent the result of periglacial processes that prevailed during cold periods more than 10,000 years ago. As with the glacial chapter, this account of the periglacial geomorphology also needs to base itself upon processes that no longer or only to a limited extent take place in the areas today. Consequently, this chapter will include an overview of some of the most important periglacial processes and deposits and their effects upon landscape development as influenced by variations in periglacial environmental conditions, lithology, and vegetation cover. Most landscapes that were glaciated during the Weichselian have accentuated relief, especially where subsequent human modification has been relatively modest. It is probable that the glaciated parts of Europe were also accentuated after the Saalian glaciation, but today smooth surfaces and gentle slopes characterize the Saalian areas. During interglacial periods relatively little landscape modification has taken place, and the difference in morphology between the Weichselian glacial landscape and the areas beyond is mainly due to the activity of periglacial processes. As a consequence these European landscapes can be regarded as periglacial. Even where a periglacial overprinting can be strongly demonstrated in the geomorphology of many western European landscapes the expression ‘periglacial landscape’ has not been widely used. There may be two main reasons for this. First, even if landforms resulting from periglacial processes may be geographically widespread, they are not normally as eye-catching and morphologically diverse on a local scale as are those resulting from glacial activity. Secondly, it is difficult to geographically delimit a periglacial area: in relation to a glaciated area where the criterion is whether the ice was there or not, the delineation of a periglacial area is dependent on much more subtle features and arbitrary criteria. Further, landscapes that show general imprints of past periglacial conditions often contain areas that bear identifiable imprints of the dominant activity of a single agent, such as water, wind, or gravity. Even if some of these activities may be particularly efficient in cold climates, they are nevertheless of a wider occurrence.

Testo completoAbstract (sommario):
Using a wide variety of examples, this chapter emphasizes evidence that all landscapes and ecosystems today reflect not only climate change but also intensive and extensive past human impacts. They cannot be interpreted solely based on conditions evident today. The imprints of past human activities which can be obvious or subtle, must be unraveled for understanding the system today. Historical ecology integrates various drivers of change, and stability, using interdisciplinary methods, to provide a deeper understanding of structure and function today. Conservation seeks in some places to maintain ecosystems that have arisen over centuries or even millennia due to human impact, for example, ancient woodlands and upland meadows in Europe. In many parts of the world such ancient systems are reservoirs of high biodiversity. Historical research illuminates the historical factors that contribute to this diversity, assisting in planning for conservation. A major point is that ecologists are apt to make mistakes in interpreting patterns and processes as well as in conservation and restoration if they do not consider the history of sites, which provides evidence of past variability and of processes that have led to the current conditions of the system.

Testo completoAbstract (sommario):
Maurice Carême (1899–1978) was a Belgian francophone poet. We present revisiting the appreciation that is sometimes assigned to a « poet of images » to deepen that « above all visual » of a poet who writes « with the gifts of observation » (Moremans 1930 : 19), and gives, in his poetic intuition, a content to see. The visual, in symbiosis with the tangible, manifests itself in the work of Maurice Carême through the fascination with the gestures of graphic, pictorial and even sculptural production. The passion for the imprints left by these gestures is expressed by the presence of a pictorial isotopy, by the frequent recurrence of words such as trace, draw, paint, sketch, model and other terms belonging to the same semantic field, as well as by the use of the presentative « there ». In this synthetic designation, the poet sums up, in a simulation of gestures und unique denomination, the landscape and its outlines. Explicitly referring to pictorial techniques is one of the most visible processes these expressions are part of a network of visual patterns that relate both to the gestures of writing and painting. This leads to anchoring in the reader the impression of visual poetry

Pure titanium (commercial pure cpTi) is an ideal dental implant material without the leeching of toxic alloy elements. Evidence has shown that unsmooth implant surface topologies may contribute to the osteoblast differentiation in human mesenchymal pre-osteoblastic cells, which is helpful to avoid long-term peri-abutment inflammation issues for the dental implant therapy with transcutaneous devices. Studies have been conducted on the grit blasted, acid etched, or uni-directional grooved Ti surface. However, for these existing approaches, the surface quality is difficult to control or may even damage the implant. A novel idea has been studied in which more complex two-dimensional (2D) patterns can be imprinted into the dental implant material of cpTi by high energy pulse laser peening (HEPLP). The strong shock wave generated by HEPLP press a stainless steel grid, used as a stamp, on Ti foils to imprint a 2D pattern. In this study, the multiple grid patterns and grid sizes were applied to test the cell’s favor. The HEPLP induced shock wave pressure profile and history were simulated by a 2D multi-physics hydrodynamic numerical analysis for a better understanding of this technique. Then, the cell culture tests were conducted with the patterned surface to investigate the contribution of these 2D patterns, with the control tests of the other existing implant surface topography forming approaches.

Testo completoAbstract (sommario):
Coned and threaded type connection valves, fittings and tubing up to sizes of 9/16” are typical high pressure components used on the initiator injection system of a Low Density Polyethylene LDPE facility. The process pressures of up to 360 MPa (52,200 psi) on the reactor side require even higher pressures on the initiator injection lines. Based on the differential pressures and the challenging environment 414 MPa (60,000 psi) has been defined as an appropriate pressure rating for such components. Valves, fittings and tubing with this pressure rating are more or less standardized and available from multiple sources on the market. However, the technical challenges in designing and manufacturing components for this duty are sometimes under-estimated and design improvements can lead to a higher process safety and a reduced downtime. This paper covers the design requirements and has a specific focus on a filter with screwed element and a check valve with ceramic ball. The majority of high pressure in-line filters on the market have a sintered element that is press-fitted into the filter body. This design has some disadvantages in case of fast depressurizations as they occur when a safety valve or a rupture disk blows off. The sudden differential pressure may cause the element to move inside the body, and this can be accompanied by cracking of the element. Parts of the broken sintered element are a risk to the process since they would move downstream followed by a contamination of the reactor. A new generation of such filters with screw-in elements was designed and tested. The R&D work resulted in an extended element that fits into a modified filter body with standard outside dimensions. Before performing a field test at a LDPE plant three prototype samples went through intensive testing at the manufacturer’s facilities. Check valves are typical components used in order to maintain the flow in one direction. For liquids the metal to metal sealing ball type is the most common. Since the process pressure exposes the mating parts — ball and orifice — to high compression forces, imprints and marks on the ball surface are sometimes experienced. The material of these types of balls is typically bearing steel which has high mechanical strength but limited corrosion resistance. In order to improve the cycle life of high pressure ball check valves alternative materials were looked at. During the further product improvement a check valve with ceramic ball was designed and lab tested at the manufacturer’s facilities.

This study is aimed at determining the impact that web-based middleware systems can imprint in enhancing learning and assessment. Representative samples of students attending introductory computer classes at the Technikon, were assessed to determine the level of their knowledge and use of the Internet. Very few of them demonstrate high Internet knowledge and awareness. Over 80% indicate willingness to surf the web more, if there is a compelling situation that forces or encourages them. One group of students, were given assignments and tests throughout the semester via the on-line system developed, and were subsequently reassessed at the end of the semester. The result showed dramatic improvement in the level of their knowledge and use of the Internet as well as increased speed of carrying out assigned tasks on the Internet. The study concludes there is a huge impact that web-based middleware can imprint in enhancing learning even in contact institutions.

As human society transitions from an agricultural to an industrial and knowledge-based economy, the functions of craftsmanship and artisans is changing. This paper believes that craftsmanship is a narrative process in which each age leaves its imprint. It is critical to embrace external changes and respond to these challenges in order to form new craftsmanship. The research believes that the craft community either grows, declines, or even disappears due to its interaction with the external environment. We emphasize enhancing the resilience of the craft community to survive in the external changes by changing internal structure functions and connecting external resources to establish new economic activities.

Testo completoAbstract (sommario):
The new 6.5-m honeycomb mirror for the Multiple Mirror Telescope Observatory on Mt. Hopkins was polished with a 1.2-m stress lap on the Large Optical Generator at the Steward Observatory Mirror Lab. Problems during the last few months of polishing led to the development of a system for monitoring the drag forces on this lap. Records of the drag forces during each stroke were then used to compute an effective drag coefficient as well as the frictional power dissipated per unit area of mirror as a function of radius. While the glass removal rate was found to track the observed distribution of expended frictional energy quite nicely, the system turned out to be even more valuable as a tool for identifying anomalous drag conditions before they put a significant imprint on the mirror.

Testo completoAbstract (sommario):
Uniform irradiation of laser beam is needed for the directly driven inertial confinement fusion, laser-chemistry and industrial applications such as laser welding, semiconductor processing and laser microfabrication. For improving the irradiation uniformity on a fusion target, several beam smoothing techniques such as a random phase plate (RPP)1, induced spatial incoherence (ISI)2, smoothing by spectral dispersion (SSD)3 and kinoform phase plate (KPP)4 have been proposed. The RPP has energy loss of ~ 15 % by a large diffraction angle, and the ISI and the SSD have imprint problems by instantaneous speckle pattern. The precise KPP with a continuous phase distribution is difficult to fabricate, even if the energy loss can be reduced to 5%. We are developing an active optical system to compensate (or control) a wavefront aberration included in a large-scale laser system for fusion. Shack-Hartmann wavefront sensor using a large F-number plastic micro-lens array5 and continuous faceplate type deformable mirror6 have been developed and their good performance has been demonstrated.

Testo completoAbstract (sommario):
Due to the aging of structures, the issues of plant life management and license extension are receiving increasing emphasis in many countries. Understanding failure of structures due to random roughness on surfaces at early stages of degradation is therefore crucial. It has been shown that even slightly sinusoidal roughness can increase stress concentration by a factor of 2 or 3, which can be critical for a brittle component due to the significant reduction of its load-carrying capacity, even with slight roughness. A more in-depth fracture analysis of surfaces possessing random roughness is needed in order to more profoundly understand, and hence develop models that will predict more accurately, failure of structural materials exposed to degrading, in-service conditions. Using a technique previously developed and successfully applied, replicates of random rough surfaces, imprinted with various levels of degradation, and at three distinct auto correlation lengths, were realized and mechanical testing was performed on them. The stress, strain and energy at fracture are reported. Finite element analysis was carried out to elucidate experimental results. Besides the expected reduction of energy at fracture with degradation, a relaxation region was observed where the energy slightly increases. This phenomenon implies that even after degradation has progressed there is a local maximum of energy at fracture due to the competing effect of tendons and growth of pits. The results find applications on the early stage of maintenance of surfaces of structures in service.

Testo completoAbstract (sommario):
A numerical analysis of two different effusion cooled plates, with a feasible arrangement for combustor liner application, is presented in this paper. Though having the same porosity and very shallow injection angle (17°), the first configuration presents a “conventional” circular drilling, while the other has “shaped” holes with such an elliptical cross-section that leads to a circular imprint on the cooled surface. Either geometries were the object of an experimental survey in which both adiabatic and overall effectiveness were measured. In order to compensate for the lack of detailed aerodynamic measurements, 3D CFD computations were performed for the two geometries. Steady state RANS calculations were carried out using a k–ε Two Layer turbulence model, both in the standard isotropic and in an algebraically corrected non isotropic version specifically tuned to better predict the lateral spreading of jets in a cross flow. Flow characteristic reproduce typical effusion cooled combustor liner conditions with blowing ratio of 5 and coolant jet Reynolds number of 12500. Even though good agreement could not be obtained comparing thermal adiabatic effectiveness with experiments, the findings of the experiments regarding the rating of the cooling efficiency of the two configurations were confirmed. Additionally, conjugate simulations were performed for the circular hole geometry in order to quantify heat transfer effects and to directly compare them with raw experimental overall effectiveness data.

The Covid-19 pandemic has left no corner of the world untouched. To cite just one figure, 100 million people have been pushed into poverty, according to a recent World Bank study. The two-speed recovery from the pandemic, depending on vaccine availability, is expected to leave lasting imprints on the economic performances of countries, which data suggest will have a disproportionate effect on forcibly displaced persons and their host communities. This summary highlights key messages from research focusing on how people displaced by war and conflict have been affected by Covid 19 and its secondary impacts. Diverse lived experiences are explored, ranging from the erosion of forcibly displaced persons’ rights during the pandemic, to Syrian refugees with disabilities in Turkey, to displaced Rohingya in Bangladesh. This Research for Policy and Practice Paper sets out examples of the multidimensional social and economic challenges displaced people are facing during the pandemic and presents a series of evidence-based recommendations for positive change that could be achieved even in the most challenging contexts.
