Ginter Books | 2014 | ISBN: 0989258335 | English | 76 pages | PDF | 177.51 MB
The Curtiss XP-55 Ascender was a tailless swept-wing WWII pusher fighter design born out by the USAAC 1940 fighter competition. The USAAC was looking for a fighter to counter the threat of the German Bf-109 and the Japanese Zero and replace the obsolete P-35s, P-36s and the front line P-40s just entering service. From this competition three unusual pusher prototypes were ordered, the Consolidated XP-54, Curtiss XP-55, and the Northrop XP-56. A low powered full scale flying model (model CW 24B)was built out of wood and cloth to substantiate the flying qualities, and was first flown on December 2, 1941. The XP-55 mock-up was completed in August 1942, and the first of three XP-55s was completed on June 26,1943 with its first flight being conducted on July 13, 1943. The first aircraft was destroyed on November 15, 1943. Changes deemed necessary were incorporated in the second airframe in which performance testing began on September 16, 1944. Although the much more capable P-38, P-47, and P-51 had entered service, research into the XP-55s unusual design continued. The third XP-55 had entered flight testing in April 1944 and was used at Eglin Field for armament tests before being lost during a war bond rally display on May 27, 1945. By then, the program had been terminated. Today, the second XP-55 presides in restored condition at the Kalamazoo Air Museum.

Free Download Scott Slovic, "Currents of the Universal Being: Explorations in the Literature of Energy"
English | ISBN: 0896729281 | 2015 | 288 pages | PDF | 10 MB
Energy scholar Vaclav Smil wrote in 2003, "Tug at any human use of energy and you will find its effects cascading throughout society." Too often public discussions of energy-related issues become gridlocked in debates concerning cost, environmental degradation, and the plausibility (or implausibility) of innovative technologies. But the topic of energy is much broader and deeper than these debates typically reveal. The literature of energy bears this out―and takes the notion further, revealing in vivid stories and images how energy permeates the fundamental nature of existence. Readings in this collection encompass a wide array of topics, from addiction to oil to life "off the grid," from the power of the atom to the power of bicycle technology. Presenting a wide array of poetry, fiction, nonfiction, and interviews―ranging from George Eliot's nineteenth-century novel Mill on the Floss to Sandra Steingraber's recent writing on the subject of fracking―this first-of-its-kind anthology aims to capture the interest of the general reader as well as to serve as a potential textbook for college-level writing classes or environmental studies classes that aspire to place the technical subject of energy into a broader cultural context.

English | ISBN: 1803275839 | 2023 | 456 pages | PDF | 42 MB
The twenty-second Current Research in Egyptology conference was held at the Universite Paul Valery- Montpellier 3 on 26th-30th September 2022. From 250 attendees in person and online, young scholars in Egyptology from different institutions all over the world presented ninety-four papers and twenty-four posters. September 1822 witnessed a milestone event that marked the birth of scientific Egyptology: the young Jean-Francois Champollion from Figeac outlined the principles of Egyptian hieroglyphic writing in his famous Lettre a M. Dacier. 2022 also marked the centenary of another important milestone in Egyptology: the discovery of the tomb of Tutankhamun. For these reasons, the congress celebrated the history of Egyptology and associated research with dedicated sessions, making them a focal point of the event. The present volume collects thirty-two papers on various topics from the history of Egyptology to archaeology and material culture, from the Predynastic to the Roman period, through history and epigraphy, as well as new technologies.

Free Download Tiago Tomé, "Current Approaches to Collective Burials in the Late European Prehistory: Proceedings of the XVII UISPP World Congress "
English | ISBN: 1784917214 | 2018 | 140 pages | PDF | 6 MB
The present volume originated in session A25b ('Current Approaches to Collective Burials in the Late European Prehistory') of the XVII World Congress of the International Union of the Prehistoric and Protohistoric Sciences (UISPP), held in Burgos in September 2014. Collective burials are quite a common feature in Prehistoric Europe, with the gathering of multiple individuals in a shared burial place occurring in different types of burial structures (natural caves, megalithic structures, artificial caves, corbelled-roof tombs, pits, etc.). Such features are generally associated with communities along the agropastoralist transition and fully agricultural societies of the Neolithic and Chalcolithic. For a long time, human skeletal remains exhumed from collective burials were dismissed as valuable sources of information, their studies being limited mostly to morphological assessments and subsequent classification in predefined 'races'. They currently represent a starting point for diversified, often interdisciplinary, research projects, allowing for a more accurate reconstruction of funerary practices, as well as of palaeobiological and environmental aspects, which are fundamental for the understanding of populations in the Late Prehistory of Europe and of the processes leading to the emergence of agricultural societies in this part of the world. The articles in this volume provide examples of different approaches currently being developed on Prehistoric collective burials of southern Europe, mostly focusing on case studies, but also including contributions of a more methodological scope.

Free Download Current Antipsychotics By Rebecca Kuepper, Mette Skinbjerg, Anissa Abi-Dargham (auth.), Gerhard Gross, Mark A. Geyer (eds.)
2012 | 418 Pages | ISBN: 3642257607 | PDF | 4 MB
Six decades after the serendipitous discovery of chlorpromazine as an antipsychotic and four decades after the launch of clozapine, the first atypical or second generation antipsychotic, psychopharmacology has arrived at an important crossroad. It is clear that pharmacological research and pharmaceutical development must now focus on complementary or even alternative mechanisms of action to address unmet medical needs, i.e. poorly treated domains of schizophrenia, improved acceptance by patients, better adherence to medication, safety in psychoses in demented patients, and avoiding cardiac and metabolic adverse effects. The first completely novel mechanisms evolving from our insights into the pathophysiology of psychotic disorders, especially the role of glutamatergic mechanisms in schizophrenia, are now under development, and further principles are on the horizon. This situation, in many respects similar to that when the initial second-generation antipsychotics became available, can be rewarding for all. Preclinical and clinical researchers now have the opportunity to confirm their hypotheses and the pharmaceutical industry may be able to develop really novel classes of therapeutics. When we were approached by the ✅Publishers of the Handbook of Experimental Pharmacology to prepare a new volume on antipsychotics, our intention was to capture both, the accumulated preclinical and clinical knowledge about current antipsychotics as well as prospects for new and potentially more specific antischizophrenia principles. These efforts should be based on the pathophysiology of the diseases and the affected neurotransmitter systems. Since preclinical research on antipsychotic compounds is only reliable when intimately linked through translational aspects to clinical results, we decided to include clinical science as well. It turned out that that this endeavor could not be covered by a single volume. We thank the editorial board and the ✅Publishers for supporting our decision to prepare two volumes: Current Antipsychotics and Novel Antischizophrenia Treatments. These topics cannot really be separated from one another and should be seen as a composite entity despite the somewhat arbitrary separation of contributions into two volumes. The continuing challenges of developing improved and safer antipsychotic medications remain of concern and are discussed in the first volume. The new opportunities for the field to develop and license adjunctive treatments for the negative symptoms and cognitive deficits that are treated inadequately by existing compounds have been incentivized recently and provide the focus for the second volume. We hope these collective contributions will facilitate the development of improved treatments for the full range of symptomatology seen in the group of schizophrenias and other major psychotic disorders.Gerhard Gross, Ludwigshafen, GermanyMark A. Geyer, La Jolla, CAThis volume will try to put current therapy - achievements, shortcomings, remaining medical needs - and emerging new targets into the context of increasing knowledge regarding the genetic and neurodevelopmental contributions to the pathophysiology of schizophrenia. Some of the chapters will also deal with respective experimental and clinical methodology, biomarkers, and translational aspects of drug development. Non-schizophrenia indications will be covered to some extent, but not exhaustively.

Free Download Culture Negative Orthopedic Biofilm Infections By G. D. Ehrlich, P. J. DeMeo, J. W. Costerton (auth.), Garth D. Ehrlich, Patrick J. DeMeo, J. William Costerton, Heinz Winkler (eds.)

During the recent transition between acute diseases caused by swarms of single planktonic bacteria, and chronic infections caused by bacteria growing in slime-enclosed biofilms, a general clinical consensus has emerged that pathologies with bacterial etiologies are frequently culture negative. Because biofilm infections now affect 17 million Americans per year (killing approximately 450,000), the suggestion that these common and lethal infections regularly go unnoticed by the only FDA-approved method for their detection and characterization is a matter of urgent concern. Biologically, we would expect that planktonic bacterial cells would colonize any new surface, including the surface of an agar plate, while the specialized sessile cells of a biofilm community would have no such proclivity. In the study of biofilm diseases ranging from otitis media to prostatitis, it was found that direct microscopy and DNA- and RNA-based molecular methods regularly document the presence of living bacteria in tissues and samples that are culture negative. The editors selected orthopedic biofilm infections as the subject of this book because these infections occur against a background of microbiological sterility in which modern molecular methods would be expected to find bacterial DNA, RNA-based microscopic methods would be expected to locate bacterial cells, and cultures would be negative. Moreover, in Orthopedics we find an already biofilm-adapted surgical group in which current strategies are based on the meticulous removal of compromised tissues, antibiotic options as based on high biofilm-killing local doses, and there are practical bedside strategies for dealing with biofilm infections. So here is where the new paradigm of biofilm infection meets the equally new paradigm of the culture negativity of biofilms, and this volume presents a conceptual synthesis that may soon combine the most effective molecular methods for the detection and identification of bacteria with a surgical discipline that is ready to help patients.

Free Download Sasha Verma, "Cultural Expression in the Old Kingdom Elite Tomb "
English | ISBN: 1905739788 | 2014 | 294 pages | PDF | 21 MB
Cultural Expression in the Old Kingdom Elite Tomb considers the material and immaterial culture left behind by the ancient Egyptian elite in their tombs starting some 5000 years ago. The book intends to understand this culture reflecting the 'intention' of the ancient Egyptians. All these 'intentions' are now inaccessible to us, a paradox indeed. The author starts by examining the ways in which other Egyptologists have understood tomb culture over the past century. Two main clusters of thought dominate the history of this topic, the literal and/or the symbolic meaning. The literal is a popular approach for the modern world; the symbolic encompasses the ancient Egyptians' ideas about the meaning of life in this and the next world, and metaphysical perfection. The author uses a third mid-way course between the literal and the symbolic; i.e. an attempt to study the evidence in its reality and to search for common, universal factors which may be present and which may aid understanding. The result is an inventory, analysis and synthesis of the core components of Egyptian cultural dynamics as reflected in the iconographic evolution of Old Kingdom elite tombs. New horizons are opened up for describing and interpreting cultural data of many different levels (identity, ideology as social layers, and static versus dynamic as cultural mechanisms). The work goes beyond mainstream Egyptology, because the findings, apart from a specific Egyptian core, also have universal implications since comparison with other cultures shows comparable phenomena.
