    Stüwe, Kurt

    2015-04-01

    2012 marked the 100st anniversary of the seminal publications on Continental Drift Theory by Alfred Wegener. These publications (and Wegener's book "On the origin of the continents", published three years later) are widely accepted to be the fundamental breakthrough that opened the path to the Theory of Plate Tectoncis and ultimately the path to modern Geodynamics some 50 years later. In the same historic year of the 1912 publications, Alfred Wegener set off for what was to become the most dramatic of his three Greenland expeditions. On this expedition Wegener and Koch crossed the entire northern icecap of Greenland. In honour of the hundreds anniversary of Wegener's publications, the Austrian Academy of Sciences funded an expedition to trace the footsteps of the 1912 expedition in the spirit of Alfred Wegener, while also conducting modern Earth Science. This expedition that was conducted in summer 2014. For the expedition, a 1952 Cessna180 was acquired in Alaska, adapted with bush wheels, wing extensions and extra tanks and was flown by the author and one of the worlds most renown bush pilots from Alaska in a 10 day effort to Greenland. There, the entire NE Greenland Caledonides were covered and photographed. Field work for a masters projects was conducted and samples were collected from a series of some of the most remote locations in the Caledonides ever visited. Most spectacularly, the original sled of Wegeners 1912 expedition was found some 30 kilometers from its expected location in the Dove Bugt Region of northeastern Greenland.

    AIMS--To highlight an uncommon but characteristic gingival lesion associated with Wegener's granulomatosis, emphasising the presence of pseudoepitheliomatous hyperplasia, microabscesses, and multinucleate giant cells; and the paucity of the currently accepted histopathological criteria of Wegener's granulomatosis--namely necrosis, vasculitis, and granulomata. METHODS--The histopathological features of a gingival biopsy specimen from a case of Wegener's granulomatosis limited to the upper aerodigestive tract in a 36 year old woman were compared with those of 14 similar reported cases. RESULTS--Pseudoepitheliomatous hyperplasia, microabscesses, and multinucleate giant cells were recorded as present in almost all cases of gingival Wegener's granulomatosis. Necrosis, vasculitis, and granuloma formation were present in only a few cases. CONCLUSIONS--The combination of pseudoepitheliomatous hyperplasia, microabscesses, and multinucleate giant cells in a gingival biopsy specimen from erythematous, swollen gums, clinically resembling over-ripe strawberries, in a patient with a severe systemic upset, is so typical of Wegener's granulomatosis as to be virtually diagnostic. Recognition of this characteristic lesion may aid early diagnosis and treatment in cases where other diagnostic variables are absent. Images PMID:8408694

    Eight years of daily rainfall data from WegenerNet were analyzed by comparison with data from Austrian national weather stations. WegenerNet includes 153 ground level weather stations in an area of about 15 km × 20 km in the Feldbach region in southeast Austria. Rainfall has been measured by tipping bucket gauges at 150 stations of the network since the beginning of 2007. Since rain gauge measurements are considered close to true rainfall, there are increasing needs for WegenerNet data for the validation of rainfall data products such as remote sensing based estimates or model outputs. Serving these needs, this paper aims at providing a clearer interpretation on WegenerNet rainfall data for users in hydro-meteorological communities. Five clusters - a cluster consists of one national weather station and its four closest WegenerNet stations - allowed us close comparison of datasets between the stations. Linear regression analysis and error estimation with statistical indices were conducted to quantitatively evaluate the WegenerNet daily rainfall data. It was found that rainfall data between the stations show good linear relationships with an average correlation coefficient (r) of 0.97 , while WegenerNet sensors tend to underestimate rainfall according to the regression slope (0.87). For the five clusters investigated, the bias and relative bias were - 0.97 mm d-1 and - 11.5 % on average (except data from new sensors). The average of bias and relative bias, however, could be reduced by about 80 % through a simple linear regression-slope correction, with the assumption that the underestimation in WegenerNet data was caused by systematic errors. The results from the study have been employed to improve WegenerNet data for user applications so that a new version of the data (v5) is now available at the WegenerNet data portal (www.wegenernet.org).

    The article series provides a written and pictorial account of the Danish pharmaceutical industry's products from their introduction until about 1950. Part 3 deals with products from the company founded by Alfred Benzon in 1849. Alfred Nicolai Benzon owned the Swan Pharmacy in Copenhagen. In 1863 he started an independent company manufacturing branded pharmaceuticals, thus combining the pharmacy's activities with the wholesale business. The family owned the company until 1952, when it was converted into a foundation. After several restructuring rounds, the medicine production business continued as Benzon Pharma A/S until 1990, when Nycomed Pharma A/S bought up all the branded pharmaceuticals. As the first pharmaceutical company in Denmark, Alfred Benzon was an industrial frontrunner in the country at the time, supplying not only the domestic market but foreign markets as well. Alfred Benzon was the first Danish company to produce ether for anesthesia, and malt extract, a dietetic preparation. The high quality of both products made them valuable export articles. In the early 1890s, Alfred Benzon became the first Danish company to start the research-based production of extract of thyroid glands from slaughtered cattle. This was the beginning of a long-standing specialization in producing organotherapeutic substances from animal organs originating from Danish animal husbandry. In 1932 the company had 26 preparations of this type in its range, many of them on the market for several years. These medicine substances included iron preparations and effervescent salts followed by sulfonamides, synthetic hormones and a substance to counteract motion sickness.

    The theory we now know simply as 'evolution' was first presented to the scientific world one and a half centuries ago, on 1 July 1858, when the work of two men, Alfred Russel Wallace and Charles Robert Darwin (1809-82), was jointly read at the Linnean Society. While Charles Darwin has rightly taken his place in history as one of the greatest scientists of all time, Alfred Russel Wallace has been largely forgotten outside of the scientific community. However, Wallace was a prolific researcher and writer with interests in a wide range of topics, from medicine to economics.

    Wegener's granulomatosis is a necrotizing granulomatous vasculitis of autoimmune origin that primarily affects the upper and lower airways and kidneys. It is very rare in children and adolescents. When started at a young age it is often associated with subglottic stenosis. Subglottic stenosis is a potentially fatal manifestation of Wegener's granulomatosis. Its diagnosis requires a high index of suspicion since it might develop in the absence of other signs of activity. Occasionally, subglottic stenosis may present as the initial manifestation of the disease. Diagnosis is confirmed by endoscopic visualization of the lesion. The treatment is complex, and it often requires repeated interventions due to restenosis. We present a 13-year-old patient with subglottic stenosis secondary to Wegener's granulomatosis. We describe the clinical manifestations, diagnosis and treatment of this rare cause of respiratory distress in the pediatric population. Sociedad Argentina de Pediatría.

  13. Forced Migration as Public Relations Process? Lothar B. Kalinowsky and the Trans-Atlantic Transfer of Electroconvulsive Therapy.

    PubMed

    Stahnisch, Frank W

    2016-01-01

    Research in biological psychiatry during the first half of the 20 th century was based upon a wide range of interrelated disciplines, including neurology, neuroanatomy, neuropathology, and experimental biology. The work of German-American psychiatrist and neurologist Lothar B. Kalinowsky (1899-1992) is taken here as an example of how such fields could be combined to produce a highly innovative and multidimensional research program in clinical neuroscience. Kalinowsky functioned exceptionally well in both scientific and clinical cultures despite the marked contextual differences between the Charité in Berlin and his later workplace in New York's Columbia Medical School. The innovative ideas exemplified by Kalinowsky's efforts, however, sometimes amounted to a dubious advantage for émigré clinical neuroscientists: they easily led to incommensurable scientific views, and sometimes even resulted in the marginalization of the innovator from existing research programs.

    The emigration of Lothar Kalinowsky (1899-1992) might, at first glance, seem to be a history of coincidence and twists of fate, but it is shown to be a truly entangled and intertwined history and story. The international introduction of electroconvulsive therapy was not only closely involved with the political, scientific and economic conditions during World War II, but the story of Kalinowsky's relevance to it emerges from competing stories, told differently in Europe and the USA - and by Kalinowsky himself. Tracing these stories up to the end of the 1960s reveals Kalinowsky as an influential inheritor and patron of Berlin Biological Psychiatry, rather than telling the history of an émigré innovator of international neuropsychiatric research. © The Author(s) 2015.

    Dr Alfred Stephens was the co-founder of the Liverpool Children's Infirmary. The institution was funded initially by Matthew Gregson (1800-76) and later by public subscription. Opened in 1851, it was the second Children's Hospital in England. Alfred Stephens was a general practitioner without higher qualifications. In due course he perceived that the free treatment of children at the Infirmary affected his income and he redirected patients to his practice. This led to confrontation with his colleagues and the Board of the Infirmary, and good relations were never restored. His name has not been commemorated nor his charitable work remembered.

    The research level products of the Integrated Multi-Satellite Retrievals for Global Precipitation Measurement (IMERG "Final" run datasets) were compared with rainfall measurements from the WegenerNet high density network as part of ground validation (GV) projects of GPM missions. The WegenerNet network comprises 151 ground level weather stations in an area of 15 km × 20 km in south-eastern Austria (Feldbach region, ˜46.93° N, ˜15.90° E) designed to serve as a long-term monitoring and validation facility for weather and climate research and applications. While the IMERG provides rainfall estimations every half hour at 0.1° resolution, the WegenerNet network measures rainfall every 5 minutes at around 2 km2 resolution and produces 200 m × 200 m gridded datasets. The study was conducted on the domain of the WegenerNet network; eight IMERG grids are overlapped with the network, two of which are entirely covered by the WegenerNet (40 and 39 stations in each grid). We investigated data from April to September of the years 2014 to 2015; the date of first two years after the launch of the GPM Core Observatory. Since the network has a flexibility to work with various spatial and temporal scales, the comparison could be conducted on average-points to pixel basis at both sub-daily and daily timescales. This presentation will summarize the first results of the comparison and future plans to explore the characteristics of errors in the IMERG datasets.

    1996-10-01

    Alfred Nobel never spoke publicly about his problems of ill health, but a detailed, subjective record has recently been published in the form of 216 letters written to his mistress during an 18-year period. His descriptions of constant pain, debilitating migraine, and "paralyzing" fatigue permit a hypothesis that he might have had a long struggle with fibromyalgia. This does not preclude his having suffered other illnesses as well. He thought he had heart disease, which his physicians denied until his final years, when he was diagnosed with angina pectoris. He died of a cerebral hemorrhage in 1896 at the age of 63. His letters describe a 30-year search for diagnosis from the best physicians in Europe. He was ridiculed by many people as a hypochondriac, and he never received a diagnosis for "the pain that will not go away." This may well have contributed to the bitterness and depression of his final years. Increasing worldwide interest and research in this elusive syndrome will hopefully prevent a repetition of the Nobel story of a century ago.

    An explanation is to be found in plate tectonics, a concept which has revolutionized thinking in the Earth sciences in the last 10 years. The theory of plate tectonics combines many of the ideas about continental drift (originally proposed in 1912 by Alfred Wegener in Germany) and sea-floor spreading (suggested originally by Harry Hess of Princeton University).

    We have described a rare case of Wegener's granulomatosis in our 41-year old patient, located in the nose, larynx and ear. The disease usually presents as a triad of respiratory, vascular and kidney location. It may occur as a rapid or indolent progress. We have shown in our paper diagnostic difficulties connected with this disease. The biopsies of involved organs and blood tests are the best steps of establish proper diagnosis. Antineutrophil cytoplasmic antibodies (ANCA) are typical markers of Wegeners's granulomatosis. The conservative therapy including immunosuppression and surgical treatment (laserotherapy) are main methods of management. Our patient was given antibiotic therapy, and immunosuppressive therapy. Her condition improved during the first hospitalisation. Remission lasted very short, and she was admitted to the hospital again and underwent intensive investigations and therapy. We observed dyspnea caused by subglottic stenosis. The histologic examination of the tracheal mucosa showed granulomatous inflammation. After intensive therapy our patient felt better. She has been in our records till now, we observe no progress of disease. Finally, we would like to pay attention to the fact, that early diagnosis is important to prevent complications such subglottic stenosis which can lead to death.

    Spontaneous hemothorax is a rare condition. Its causes are multiple but sometimes they remain unknown. In some patients, thoracotomy may be the only means to determine hemothorax origin. Vasculitis have not been reported as a common cause of spontaneous hemothorax. Pregnancy does not appear to have causal or aggravating effect on spontaneous hemothorax or on vasculitis. We here report the peculiar case of a young patient presenting during pregnancy with spontaneous hemothorax secondary to Wegener's vasculitis. The latter was diagnosed by pleural biopsy performed during exploratory thoracotomy and confirmed by ANCA assays.

    2017-04-01

    The Feldbach region in southeast Austria, characteristic for experiencing a rich variety of weather and climate patterns, has been selected as the focus area for a pioneering weather and climate observation network at very high resolution: The WegenerNet comprises 153 meteorological stations measuring temperature, humidity, precipitation, and other parameters, in a tightly spaced grid within an area of about 20 km × 15 km centered near the city of Feldbach (46.93°N, 15.90°E). With its stations about every 2 km2, each with 5-min time sampling, the network provides regular measurements since January 2007. Detailed information is available in the recent description by Kirchengast et al. (2014) and via www.wegcenter.at/wegenernet. As a smaller "sister network" of the WegenerNet Feldbach region, the WegenerNet Johnsbachtal consists of eleven meteorological stations (complemented by one hydrographic station at the Johnsbach creek), measuring temperature, humidity, precipitation, radiation, wind, and other parameters in an alpine setting at altitudes ranging from below 700 m to over 2100 m. Data are available partly since 2007, partly since more recent dates and have a temporal resolution of 10 minutes. The networks are set to serve as a long-term monitoring and validation facility for weather and climate research and applications. Uses include validation of nonhydrostatic models operated at 1-km-scale resolution and of statistical downscaling techniques (in particular for precipitation), validation of radar and satellite data, study of orography-climate relationships, and many others. Quality-controlled station time series and gridded field data (spacing 200 m × 200 m) are available in near-real time (data latency less than 1-2 h) for visualization and download via a data portal (www.wegenernet.org). This data portal has been undergoing a complete renewal over the last year, and now serves as a modern gateway to the WegenerNet's more than 10 years of high

    This article embraces the different ways a scientist traveller and his fieldworks can be perceived through the case of Alfred Grandidier in South America, in India and in Madagascar (1857-1870). Our aim is to deal with various aspects of historical scientific exploration and to draw a picture of the erudite traveller by crossing various and complementary points of view. Scientific works can be received very differently, depending on the place and the nature of the addresses, whether they are authorities wishing to take advantage of it, native people fearing for their safety or disciples glorifying their idol. The concept of science itself and the status of the scientist raise the question of mutual understanding between the explorer and his contemporaries, in Paris or in a remote place. Alfred Grandidier's example is particularly relevant to reveal different visions of scientist traveller as promoted in the 19th century, as well as the various perceptions that a scientific work can have depending on the public it impacts.

    Before 1950, cases of necrotizing vasculitis were commonly published in journals of pathology. Most of these cases were designated as polyarteritis nodosa. In 1952, the pathologist Pearl Zeek critically reviewed and summarized the literature dealing with polyarteritis nodosa and first grouped the different types of necrotizing vasculitis. But she omitted some types of not well-characterized vasculitis, among them granulomatosis with polyangiitis (Wegener's granulomatosis).

    Wegener's granulomatosis (WG) is rarely diagnosed during the reproductive years and uncommonly manifests for the first time during pregnancy. We report a case of de novo WG presenting at 30 weeks gestation with classical symptoms of WG (ENT, pulmonary). The diagnosis was confirmed by radiological, laboratory, and histological investigations. With a multidisciplinary approach, she had a successful vaginal delivery of a healthy baby. She was treated successfully by a combination of steroids, azathioprine and intravenous immunoglobulin in the active phase of disease for induction of remission and by azathioprine and steroids for maintenance of remission. The significant improvement in her symptoms allowed us to continue her pregnancy to 37 weeks when delivery was electively induced. Transplacental transmission of PR3-ANCA occurred but the neonate remained well. This case of de novo WG during pregnancy highlights the seriousness of this disease and the challenge in management of such patients.

    Alfred Bauder (or Fredi as his friends and family call him) was born on 10 May 1934 in Zurich, where he went to school. After obtaining his high school diploma in 1953, he studied chemistry and physics at the ETH Zurich department of natural sciences, which encouraged such interdisciplinary studies. He received his diploma in natural sciences with the highest distinction in 1957. Under the tutelage of Professor Hans H. Günthard at the laboratory of Physical Chemistry at ETH Zürich, he obtained his doctoral degree in 1961 with a thesis on the microwave spectrum, dipole moment and structure of cyclobutanone. This work was to set the tone for his future scientific career. After his habilitation in the field of microwave spectroscopy at ETH in 1966, he obtained the venia legendi as Private Docent for Physical Chemistry.

    Two PhD theses (Alexander Gordienko, 1912; Johannes Angerstein, 1914) and a dissertation in partial fulfillment of a PhD thesis (H. S. French, Zurich, 1914) are reviewed that deal with hitherto unpublished UV-vis spectroscopy work of coordination compounds in the group of Alfred Werner. The method of measurement of UV-vis spectra at Alfred Werner's time is described in detail. Examples of spectra of complexes are given, which were partly interpreted in terms of structure (cis ↔ trans configuration, counting number of bands for structural relationships, and shift of general spectral features by consecutive replacement of ligands). A more complete interpretation of spectra was hampered at Alfred Werner's time by the lack of a light absorption theory and a correct theory of electron excitation, and the lack of a ligand field theory for coordination compounds. The experimentally difficult data acquisitions and the difficult spectral interpretations might have been reasons why this method did not experience a breakthrough in Alfred Werner's group to play a more prominent role as an important analytical method. Nevertheless the application of UV-vis spectroscopy on coordination compounds was unique and novel, and witnesses Alfred Werner's great aptitude and keenness to always try and go beyond conventional practice.

    Medical trainees are required to undertake audit and quality improvement projects. They must also have an understanding of the principles of research and are encouraged to participate in research projects. However, the constraints of time, a lack of formal training and rotation between different training posts create barriers to audit cycle completion and pursuing research. This leads to trainees being reluctant to undertake research, facilitates poor quality research and risks incomplete audit. The Welsh Geriatricians Network (WeGeN) has been created with the aims of facilitating collaborative, trainee-led research within Geriatric Medicine in Wales, promoting research engagement and improving the research evidence base for older patients. By coordinating collaborative research projects across different sites within Wales, trainees continue existing projects at new sites, allowing completion of projects and establishing the long-term infrastructure and experienced personnel needed for high-quality research data to be gathered. WeGeN has facilitated 4 national audits, all of which are intended for peer review publication. The first project considers the service provision for the older person in the emergency department, the second Parkinson's disease, the third reviews delirium management and the fourth project considers epidemiology of surgical disease in older people. The objective of this project is to further establish and develop WeGeN as a group which facilitates high-quality research and provides the opportunity for geriatric trainees to engage in research activity. It is anticipated that the establishment of this research platform will provide a blueprint for the development of other such networks in the UK and beyond.

    Alfred Russel Wallace (1823-1913) is an important figure in the history of science, but there remain many questions about the nature of his world view, and how it developed. Here, Wallace's appreciation of the role of final causes in evolution is linked to some of its probable origins, with an emphasis on the influence of Alexander von Humboldt (1769-1859). The question is then asked whether a final causes-based scientific agenda might be possible, and answered by drawing attention to two current efforts in that direction by Adrian Bejan, and by the author. A sketch of the latter approach, adapted from Spinozian thinking, is given, with an empirical example involving drainage basin morphology that suggests structural influences of a final causes sort.

    Alfred Nobel (1833-1896), mainly known for his invention of dynamite and the creation of the Nobel Prices, was an engineer and inventor active in many fields of science and engineering, e.g. chemistry, medicine, mechanics, metallurgy, optics, armoury and rocketry. Amongst his inventions in rocketry was the smokeless solid propellant ballistite (i.e. cordite) patented for the first time in 1887. As a very wealthy person he actively supported many Swedish inventors in their work. One of them was W.T. Unge, who was devoted to the development of rockets and their applications. Nobel and Unge had several rocket patents together and also jointly worked on various rocket applications. In mid-1896 Nobel applied for patents in England and France for "An Improved Mode of Obtaining Photographic Maps and Earth or Ground Measurements" using a photographic camera carried by a "…balloon, rocket or missile…". During the remaining of 1896 the mechanical design of the camera mechanism was pursued and cameras manufactured. In April 1897 (after the death of Alfred Nobel) the first aerial photos were taken by these cameras. These photos might be the first documented aerial photos taken by a rocket borne camera. Cameras and photos from 1897 have been preserved. Nobel did not only develop the rocket borne camera but also proposed methods on how to use the photographs taken for ground measurements and preparing maps.

    South-eastern Austria is characteristic for experiencing a rich variety of weather and climate patterns. For this reason, the county of Feldbach was selected by the Wegener Center as a focus area for a pioneering observation experiment at very high resolution: The WegenerNet climate station network (in brief WegenerNet) comprises 151 meteorological stations within an area of about 20 km × 15 km (~ 1.4 km × 1.4 km station grid). All stations measure the main parameters temperature, humidity and precipitation with 5 minute sampling. Selected further stations include measurements of wind speed and direction completed by soil parameters as well as air pressure and net radiation. The collected data is integrated in an automatic processing system including data transfer, quality control, product generation, and visualization. Each station is equipped with an internet-attached data logger and the measurements are transferred as binary files via GPRS to the WegenerNet server in 1 hour intervals. The incoming raw data files of measured parameters as well as several operating values of the data logger are stored in a relational database (PostgreSQL). Next, the raw data pass the Quality Control System (QCS) in which the data are checked for its technical and physical plausibility (e.g., sensor specifications, temporal and spatial variability). In consideration of the data quality (quality flag), the Data Product Generator (DPG) results in weather and climate data products on various temporal scales (from 5 min to annual) for single stations and regular grids. Gridded data are derived by vertical scaling and squared inverse distance interpolation (1 km × 1 km and 0.01° × 0.01° grids). Both subsystems (QCS and DPG) are realized by the programming language Python. For application purposes the resulting data products are available via the bi-lingual (dt, en) WegenerNet data portal (www.wegenernet.org). At this time, the main interface is still online in a system in which

    This is a previously unpublished work by Alfred Adler that was written in 1936 as a preface to The Diary of Vaslav Nijinsky. A theory of schizophrenia is described in which characteristic prepsychotic features, especially lack of social interest and oversensitivity to real and imagined slights, lead to increasing irrationalism and preoccupation with grandiose ideas. The establishment of a cooperative therapeutic relationship and the instilling of hope are presented as central factors for successful treatment.

    A diary and an extensive correspondence of Heinrich Hertz and his family provide a meticulous documentation of his life, made available by Albrecht Folsing in 1997 through a carefully investigated biography, which permit the conclusion that H. Hertz died of Wegener's granulomatosis, 45 years before this disease had been explored. WEGENER'S GRANULOMATOSIS: The symptoms of the granulomatosis, that was first described by Friedrich Wegener in 1936 and 1939 are presented in short with literal quotations of the author: It begins with a refractory cold that will last until the end, then follow involvement of the paranasal sinuses, ears, mucous lining of mouth and pharynx, slight fever, weakness, in the final phase dissemination with nephritis, septic fever, arthritis, myalgia, paralyses leading to total immobility, exitus. The etiology is not fully understood but probably based on immunoreaction. H. HERTZ: CURRICULUM VITAE: Born in Hamburg, Germany, in 1857: after secondary school academic training in physics at Dresden, Munic and Berlin. 1885 professor of physics in Karlsruhe, then starting in 1889 at Bonn. 1887/88 exploration of the electromagnetic waves, now the basis for all radio communication, and exploration of the photoelectric effect, the basis of solar techniques. Numerous highranking distinctions. H. HERTZ: The case history is presented in detail based on numerous literal quotations from personal letters and the diary. After a few banal affections involving the teeth and toes the systemic disease became manifest in summer 1892 with a refractory cold which remained the focus of treatment until death. Granulation tissue in the nose that was excised several times: no tuberculosis, no carcinoma. Otitis with purulent mastoiditis, in October 1892 mastoidectomy, persistent purulence. Early in 1893 diagnosis of nephritis. Extraction of a superior tooth, punturing of the maxillary sinus, then twice radical opening of the maxillary sinus. Painful ankylosis and paralyses

  2. The three lost millennia of the last deglaciation (Alfred Wegener Medal Lecture)

    NASA Astrophysics Data System (ADS)

    Bard, Edouard

    2013-04-01

    Looking back more than thirty years, climate history over the last period of deglaciation was seen to portray a smooth transition between the last glacial maximum (LGM) centered around 18,000 years ago (based on radiocarbon), and the beginning of the Holocene at about 10,000 years before present. At that time, the renowned CLIMAP group used the stratigraphy available to reconstruct the glacial world by averaging paleothermometric data over a wide time window, ranging between at least 14,000 and 24,000 yr BP, over which period climate was assumed to be rather stable. Even if northern European pollen records showed several phases of vegetation shift, the exact duration and spatial coverage of these shifts was unknown and their climatic significance was not well-enough understood to be separated from other biological effects, such as plant migration following ice-sheet demise. Significant progress came from mass spectrometry developments applied to isotope geochronology in the mid- and late- 1980s. This allowed the precise analysis of radiocarbon on small samples such as foraminifera in marine sediments and enabled the measurement of U-Th ages for accurate dating of corals and speleothems. These technological improvements permitted meaningful comparisons between proxy records from the various archives originating from all latitudes and longitudes. Today, it is clear that the old LGM time window corresponds to a period of more than ten millennia during which there was significant climate variability, including a prominent cooling event at the beginning of the deglaciation. This cooling event is known as the 'Oldest Dryas' by palynologists, as 'Heinrich Event #1' (H1) by paleoceanographers, and has even been dubbed the 'Mystery Interval' by prominent authors as they puzzled while attempting to synthesize and interpret its records. The H1 drastic cooling, attributed to a pulse-like injection of ice and meltwater into the North Atlantic, was first evidenced in 1987 in sediments from the Iberian Margin. Three years later, significant improvements of the radiocarbon calibration demonstrated that about three millennia were missing from the deglaciation record. Accordingly, the LGM mean age was pushed from 18,000 to 21,000 yr BP, the midpoint of H1 was shifted from 13,500 to 16,000 yr BP, and the beginning of the Holocene was repositioned at about 11,500 yr BP. This new climate chronology was subsequently confirmed by counting 'cryovarves' within the GRIP and GISP2 Greenland ice cores. These studies have since been complemented by many other records from polar ice, marine and lacustrine sediments and cave speleothems. In addition to extending the chronology by three additional millennia, improvement also arose from the quality of the new geological archives. These archives have allowed studies at much higher resolution than was previously achieved in the framework of CLIMAP, which included many records based on deep-sea cores characterized by low sedimentation rate, and thus very susceptible to smoothing processes such as bioturbation. In addition, analytical geochemistry has only recently provided techniques adapted to the production of high-resolution time series of various proxies based on elemental ratios, on organic compounds or on stable and radiogenic isotopes. More than a dozen years after the H1 discovery, the same Iberian Margin sediments were used to show that H1 comprised at least two phases, H1a and H1b, based on ice rafted debris (IRD) and other proxies. It is now recognized that the entire H1 event (H1 sensu lato) is a three millennia-long period (ca. 17,500 to 14,500 yr BP). To illustrate the progress in this research field, I will review the key records that can be used to document the complex nature of this episode. The H1 (s.l.) included several phases of intense cooling, of precipitation changes - notably at low latitudes and in the Asian monsoon area, of retreat and decay of glacial ice-sheets - as evidenced in sediments collected in river mouths, and of sea-level rise as recorded in corals from Tahiti and Barbados. Various isotopic proxies of deep-sea ventilation have been used to identify variations during the H1 sub-phases of the Meridional Overturning Circulation (MOC), indicating that ocean heat transport was involved in the observed climate fluctuations. The various records documenting different climate parameters at many locations over the Earth can also be used in meaningful comparison with numerical model simulations performed in a transient mode. Collectively, these works allow to estimate the phase relationships between the causes (insolation and the greenhouse effect) and the often abrupt responses of the various components of the climate system, such as the atmosphere, oceans and ice sheets. Although these studies concern a naturally-occurring global warming that took place over a long time period, useful parallels will be drawn with the evolution of modern climate. In fact, the phase relationships between forcings (such as greenhouse gases and solar input) and changes in regional and global temperatures are also at the heart of modern global climate change. As for early deglaciation, the ocean can modulate warming regionally, thereby delaying, or even temporarily masking, long-term changes. Climate changes over the last century have been smaller in magnitude than those of the last deglaciation. Fortunately for us, there has been no recent collapse of gigantic ice masses such as the Laurentian and Fennoscandian ice sheets. However, most climate models show a 20 to 40% reduction of the MOC during the 21st century. Even if this change exerts only a minor influence on the projected magnitude of global warming, such a slowdown in ocean circulation change is generally sufficient to reduce the simulated warming over the North Atlantic with a resulting impact on adjacent continents, including Europe.

    Alfred Adler's significance for the concept of narcissism is presented with reference to four aspects: 1) Adler's theory of masculine protest was evidently a factor influencing Freud to turn toward the phenomenon of narcissism. 2) Present-day understanding of narcissism shows remarkable similarity to Adler's views on psychodynamics and neurotic egocentricity. 3) Some contemporary criticisms of Freud's theory of narcissism are very similar to Adler's criticism. 4) Adler's theory of social interest permits subsumption of narcissism under lack of social interest rather than acceptance of it as an expression of innate socially negative tendencies.

  5. Orographic influence on storm damage to forests in mountain areas by the example of windstorm 'Lothar'

    Schmoeckel, J.; Kottmeier, Ch.

    2003-04-01

    The extraordinary strong storm 'LOTHAR' on December 26, 1999 caused large damage in the forests of France, Switzerland and Germany. In Germany, specially the Black Forest (Schwarzwald) was concerned. In this contribution an empirical analysis of storm damage in the northern Black Forest is given. The aim is to derive the orographical influence on the windfield from the damage pattern. This is recorded approx. 5 months after the desaster by an airborne survey with a digital line scanner. From these data highly resolved, georeferenced distributions of the vegetation index are calculated (2 m x 2 m pixel size). The damaged forest areas appear with a lower vegetation index than areas with intact vegetation. Demarcation between damaged forest areas and populated or differently used areas is given by a landuse model. Mapping of the storm damages and their combination with a digital elevation model and landuse data is performed in a GIS. It is shown that the damage pattern is significantly affected by orographic factors. Large damage occurred e.g. at the location of saddles between single mountains, on mountain flanks facing to the North and Northwest, and at the windward (west) flanks of extended mountain ridges. Little damage is found in areas that presumably were protected against the wind, i.e. on the leeside (eastern) mountain flanks, in dells and niches as well as in valleys perpendicular to the mean west to southwest winds. To explain the spatially complex distribution of damages more fully, an analysis is made where characteristics of the forest and of the soil are taken into account. The knowledge gained can be profitable for future afforestation in mountain areas to stabilize forests against severe storms.

    Wegener granulomatosis (WG) is a cytoplasmic antineutrophil cytoplasmic antibody (c-ANCA)-associated, multi-system, necrotizing granulomatous vasculitis. Inflammation of the nasal or oral mucosa, and lung and kidney involvements are typical in the course of the disease. In rare cases, pituitary involvement may occur and cause panhypopituitarism. Pituitary involvement is very rare, and only two pediatric case reports have been published to date out of a total of 24 cases. This is a case report of an adolescent patient who presented with panhypopituitarism symptoms and was later diagnosed with WG. A 16-year-old female patient complained of fever, headache, purulent nasal discharge and severe muscle and joint pain. Additionally, she had polyuria and polydipsia. Investigations revealed a pituitary mass and panhypopituitarism. Positivity of c-ANCA and renal biopsy result compatible with WG confirmed the diagnosis.

    Promoting young researchers is a major priority of the German Helmholtz Association. Since more than five years graduate and postgraduate education in the field of Earth System and Environmental Science has been established in Bremen and Bremerhaven, north-western Germany. Using the network and collaboration of experts and specialists on observational and paleoclimate data as well as on statistical data analysis and climate modelling from two Universities and the Helmholtz research institute on Polar and Marine Research, master and PhD students are trained to understand, decipher and cope with the challenges of recent climate change on an highly interdisciplinary and inter-institutional level. The existing research infrastructure at the Alfred Wegener Institute in Bremerhaven (AWI), University of Bremen, and Jacobs University Bremen offers a unique research environment to study past, present and future changes of the climate system, with special focus on high latitudinal processes. It covers all kind of disciplines, climate science, geosciences and biosciences, and provides a consistent framework for education and qualification of a new generation of expertly trained, internationally competitive master and PhD students. On postgraduate level, the Postgraduate Programme Environmental Physics (PEP) at the University of Bremen (www.pep.uni-bremen.de) educates the participants on the complex relationship between atmosphere, hydrosphere (ocean), cryosphere (ice region) and solid earth (land). Here, the learning of experimental methods in environmental physics at the most advanced level, numerical data analysis using supercomputers, and data interpretation via sophisticated methods prepare students for a scientific career. Within cooperation with the Ocean University of China (OUC) students are participating one year in the PEP programme during their master studies since 2006, to get finally a double degree of both universities.

    Wegener granulomatosis classically involves the renal, respiratory, and ear, nose, and throat systems. Pulmonary hemorrhage is recognized as a severe respiratory complication. Untreated, the mortality rate approaches 90% at 2 years. We describe a case of Wegener granulomatosis with coexistent severe lung hemorrhage and pulmonary and deep vein thromboses. A 31-year-old man presented with features of vasculitis, including epistaxis, fever, and acute kidney injury with an increased serum creatinine level (3.27 mg/dL). Kidney biopsy confirmed pauci-immune crescentic glomerulonephritis, and antineutrophil cytoplasmic antibody showing a cytoplasmic staining pattern was strongly positive. Standard immunosuppression therapy (prednisolone and cyclophosphamide) was started. Eleven days later, the patient developed sudden dyspnea. A computed tomographic pulmonary angiogram showed pulmonary emboli, and ultrasound of the limbs showed ileofemoral thrombi bilaterally. Subcutaneous enoxaparin and warfarin therapy was started, but 8 days later, the patient had a massive pulmonary hemorrhage. Anticoagulation therapy was stopped, and plasma exchange was started to prevent further life-threatening hemorrhage. An inferior vena cava filter was inserted to prevent further pulmonary emboli during the period when anticoagulation was withheld. Kidney function improved, and pulmonary hemorrhage resolved after 5 plasma exchanges. Reintroduction of intravenous heparin and subsequently warfarin caused no further bleeding. We discuss the difficult management dilemma this combination of disease manifestations presents and review the current literature.

    The quest for a psychological theory to explain the effects of aesthetic surgery reached its high point in the 1920s with the adoption of Alfred Adler's theory of the inferiority complex. The basis for this theory was Adler's early work in the psychological response of the body to disease and "degeneration". Aesthetic surgeons sought out the Adlerian model rather than a Freudian one as purely psychological while its roots, and their own theories, were clearly somatic in origin.

He began his career at The Ohio State University, and spent most of his professional life at the U.S. Department of Agriculture in Washington, DC. His work spanned a diversity of topics, including bog ecology and the ecosystem services provided by wetlands, the mapping and chemical characterization of peat, and the commercial applications of peat. We present a biography and overview of his work. Dachnowski is best known today for the peat sampler that bears his name.

    During 2009, while we were celebrating Charles Darwin and his The origin of species, sadly, little was said about the critical contribution of Alfred Russel Wallace (1823-1913) to the development of the theory of evolution. Like Darwin, he was a truly remarkable nineteenth century intellect and polymath and, according to a recent book by Roy Davies (The Darwin conspiracy: origins of a scientific crime), he has a stronger claim to the Theory of Evolution by Natural Selection than has Darwin. Here we present a critical comparison between the contributions of the two scientists. Sometimes referred to as 'The other beetle-hunter' and largely neglected for many decades, Wallace had a far greater experience of collecting and investigating animals and plants from their native habitats than had Darwin. He was furthermore much more than a pioneer biogeographer and evolutionary theorist, and also made contributions to anthropology, ethnography, geology, land reform and social issues. However, being a more modest, self-deprecating man than Darwin, and lacking the latter's establishment connections, Wallace's contribution to the theory of evolution was not given the recognition it deserved and he was undoubtedly shabbily treated at the time. It is time that Wallace's relationship with Darwin is reconsidered in preparation for 2013, the centenary of Wallace's death, and he should be recognized as at least an equal in the Wallace-Darwin theory of evolution.

  15. Nuclear Planetology: Constraining the Driving Force in Wegener's Continental Drift Theory

    NASA Astrophysics Data System (ADS)

    Roller, G.

    2015-12-01

    Nuclear planetology [1] is a new research field, which aims at deciphering the nuclear physics processes responsible for the evolution of ultra-substellar objects and the driving force in Wegener's continental drift theory by means of Re-Os nuclear geochronometry [2]. Terrestrial Re/Os ratios observed within diamond sulphide inclusions [3], compatible with lunar r-process production ratios of Th/U≈1≈Au/Ir [4], drop from ≈0.8 to 0.2-0.05 for nucleogeochronometric ages between 2.3 Ga and 1.4 Ga [5]. It has therefore been argued [5,6] that the Re/Os fractionation is related to a change in oxygen fugacity due to the physics/chemistry of Earth's core after a possibly Fermi-pressure controlled core collapse [4]. Here, Pd/Ru, Pd/Pt, Pd/Ir, Pd/Os, Ru/Ir, Ru/Os, Pt/Ir or Pt/Os ratios from 24 published H chondrite components [7] are connected to their respective nucleogeochronometric ages to constrain an extended fossil fractionation record over 800 Ma. The following ranges are obtained: 0.06-1.04 (Pd/Ru), 0.06-0.79 (Pd/Pt), 0.06-1.76 (Pd/Os), 0.07-1.94 (Pd/Ir), 1.08-1.99 (Ru/Ir), 0.83-2.41 (Pt/Os), 0.82-2.64 (Pt/Ir). Comparing the Re/Os fractionation pattern of the diamond sulphide inclusions with these results and considering that Re is readily oxidized even at ultra-low oxygen fugacity, it may be concluded that (i) extremely reducing conditions within Earth's core basically preserve any unfractionated r-process element ratio until today; and (ii) nuclear/quantum physics processes leading to the observed ratios and fractionation pattern are ultimately the driving force in Wegener's continental drift theory.

    It is well known that the contribution of Alfred Russell Wallace (1823-1913) to the development of the "Darwinian" principle of natural selection has often been neglected. Here we focus on how the three anniversaries to celebrate the origin of the Darwin-Wallace theory in Germany in 1909, in 1959 in the divided country, as well as in 2009, have represented Charles Robert Darwin's and Alfred Russell Wallace's contributions. We have analyzed books and proceedings volumes related to these anniversaries, and the main result is that Wallace was almost always ignored, or only mentioned in passing. In 1909, Ernst Haeckel gave a talk in Jena, later published under the title The worldview of Darwin and Lamarck (Das Weltbild von Darwin und Lamarck), but not as the Darwin-Wallace concept. Haeckel mentions Wallace only once. In two important proceedings volumes from the 1959 anniversaries, Wallace was ignored. The only fair treatment of Wallace is given in another book, a collection of documents edited by Gerhard Heberer, for which the author selected nine key documents and reprinted excerpts (1959). Three of them were articles by Wallace, including the Sarawak- and Ternate-papers of 1855 and 1858, respectively. An analysis of the dominant themes during the celebrations of 2009 shows that none of the six topics had much to do with Wallace and his work. Thus, the tendency to exclude Alfred Russell Wallace is an international phenomenon, and largely attributable to the "Darwin industry".

    Wegener's granulomatosis (WG) is a disease of unknown etiology characterized by necrotizing granulomatous vascularitis. The upper and lower respiratory tract and kidney involvements are very common; however, its presentation as bilateral renal masses is unusual. We report a case of a 59-year-old female patient who presented with multiple bilateral renal masses. The patient presented with sinusal and ocular symptoms suggestive of WG, and positive antineutrophil cytoplasmic antibodies (c-ANCA) with an anti-PR3 pattern. Histopathologic examination of the renal biopsy specimen revealed granulomatous inflammation with vasculitis and fibrinoid necrosis. The patient management, including prednisone and cyclophosphamid, induced a marked improvement of the renal masses. This case illustrates that WG should be considered in the differential diagnosis of renal masses.

    Alfred Walter Campbell (1868-1937) established the basic cytoarchitectonic structure of the human brain while he was working as a pathologist at the Rainhill Lunatic Asylum near Liverpool in the United Kingdom. He returned to Australia in 1905 and continued doing research while establishing a neurological practice. His research over the next 17 years focused on four topics: (a) localisation in the cerebellum, (b) the neuroses and psychoses in war, (c) localisation in the cerebral cortex of the gorilla, and (d) the causes and pathology of the mysterious Australian "X" Disease (later known as Murray Valley encephalitis). In this article, I elaborate on his research in these areas, which provided evidence (a) against Louis Bolk's thesis that variation in the size of the cerebellar cortex reflected variation in the amount of cortex controlling various groups of muscle, (b) against the view that the neuroses and psychoses in war were different from those in civilian life, (c) for a parcelation of the cortex of the gorilla brain that supported his earlier findings in the higher apes, and (d) on the cause and pathophysiology of Australian "X" disease. Much of this research was overlooked, but it remains of considerable value and historical significance.

    Alfred Schnittke (1934-1998), a celebrated Russian composer of the twentieth century, suffered from several strokes which affected his left cerebral hemisphere. The disease, however, did not diminish his musical talent. Moreover, he stated that his illness in a way facilitated his work. The composer showed amazingly high productivity after his first and second injuries of the central nervous system. The main topic of this chapter is the effect of strokes on Schnittke's output, creativity, and style of music. A brief biography of the composer with the chronology of his brain hemorrhages is included. In addition, the influence of cerebrovascular lesions on creative potential of other prominent composers such as Benjamin Britten, Jean Langlais, Vissarion Shebalin, Igor Stravinsky, and Ira Randall Thompson is discussed. © 2015 Elsevier B.V.

  2. Charles Robert Darwin and Alfred Russel Wallace: their dispute over the units of selection.

    2013-12-01

    Charles Darwin and Alfred Russel Wallace independently discovered the mechanism of natural selection for evolutionary change. However, they viewed the working of selection differently. For Darwin, selection was always focused on the benefit for the individual. For Wallace, selection was as much something of benefit for the group as for the individual. This difference is traced to their different background political-economic views, with Darwin in favor of Adam Smith's view of society and Wallace following Robert Owen in being a socialist.

    Objective To assess the Birmingham Vasculitis Activity Score for Wegener's Granulomatosis (BVAS/WG) with respect to its selection and weighting of items. Methods This study used the BVAS/WG data from the Wegener's Granulomatosis Etanercept Trial. The scoring frequencies of the 34 predefined items and any “other” items added by clinicians were calculated. Using linear regression with generalized estimating equations in which the physician global assessment (PGA) of disease activity was the dependent variable, we computed weights for all predefined items. We also created variables for clinical manifestations frequently added as other items, and computed weights for these as well. We searched for the model that included the items and their generated weights yielding an activity score with the highest R2 to predict the PGA. Results We analyzed 2,044 BVAS/WG assessments from 180 patients; 734 assessments were scored during active disease. The highest R2 with the PGA was obtained by scoring WG activity based on the following items: the 25 predefined items rated on ≥5 visits, the 2 newly created fatigue and weight loss variables, the remaining minor other and major other items, and a variable that signified whether new or worse items were present at a specific visit. The weights assigned to the items ranged from 1 to 21. Compared with the original BVAS/WG, this modified score correlated significantly more strongly with the PGA. Conclusion This study suggests possibilities to enhance the item selection and weighting of the BVAS/WG. These changes may increase this instrument's ability to capture the continuum of disease activity in WG. PMID:18512722

    Alfred Russel Wallace (1823-1913) was an influential figure within Russian pre-Synthetic evolutionary biology, i.e. the time period before the Synthetic Theory of Evolution was established (ca. 1880-1930s). His major works were translated into Russian and his general ideas were read and discussed by both insiders and outsiders of scientific evolutionism. At the same time, Wallace played a controversial role in the growth of Darwinism in Russia, and Charles Robert Darwin (1809-1882) has eclipsed Wallace in his influence on Russian evolutionary thinking. In this paper we briefly outline Wallace’s impact on Russian pre-Synthetic scientific evolutionism and its general intellectual climate. We demonstrate that both Russian pro-Darwinian evolutionists and anti-Darwinians (scientific anti-Darwinians as well as creationists) were fully aware of Wallace’s contributions to the development of evolutionary theory. Yet, Wallace’s radical selectionism, as well as his controversial arguments for “design in nature”, predetermined his special place within the Russian intellectual landscape.

    In his preface to The Diary of Vaslav Nijinsky, Alfred Adler (1) found his theory of the dynamics of schizophrenia supported in the Diary, (2) alluded to Nijinsky's prepsychotic personality, and (3) briefly touched on the possibility and conditions of recovery. To add to the understanding of Adler's "Preface," this discussion (1) expands his theory of schizophrenia, (2) gives some concrete data of Nijinsky's prepsychotic personality, (3) describes two episodes of recovery subsequent to the "Preface," and (4) introduces an important aspect of Adler's theory, which he had to omit out of consideration for Nijinsky's wife, Romola-namely, her role in her husband's disorder. With the larger theoretical and historical context established. Adler's "Preface" can be appreciated for its predictive validity.

    A patient diagnosed with necrotizing scleritis, c-ANCA+ an orbital pseudotumour, and possible multiple sclerosis in 2003 was treated with oral cyclophosphamide and steroids with partial response. Between 2005-2010 she suffered self-limited episodes. In 2010 a first scleral transplant was performed with poor outcome. She was treated with rituximab, and a second graft was performed with good results. At 12 months there was no change in magnetic resonance and the second graft healed. Wegener's disease with limited involvement of the orbit and/or the eye is a rare condition. The histopathology, blood analysis, symptoms and good response to treatment are the key to its diagnosis.

    Granulomatosis with polyangiitis (GPA, formerly Wegener's granulomatosis) is a multisystem vasculitis of small- to medium-sized blood vessels. Cranial involvement can result in cranial nerve palsies and, rarely, pituitary infiltration. We describe the case of a 32 year-old woman with limited but severe GPA manifesting as progressive cranial nerve palsies and pituitary dysfunction. Our patient initially presented with localised ENT involvement, but despite treatment with methotrexate, she deteriorated. Granulomatous inflammatory tissue around the skull base resulted in cavernous sinus syndrome, facial nerve palsy, palsies of cranial nerves IX-XII (Collet-Sicard syndrome), and the rare complication of cranial diabetes insipidus due to pituitary infiltration. The glossopharyngeal, vagus and accessory nerve palsies resulted in severe dysphagia and she required nasogastric tube feeding. Her neurological deficits substantially improved with treatment including high dose corticosteroid, cyclophosphamide and rituximab. This case emphasises that serious morbidity can arise from localised cranial Wegener's granulomatosis in the absence of systemic disease. In such cases intensive induction immunosuppression is required. Analysis of previously reported cases of pituitary involvement in GPA reveals that this rare complication predominantly affects female patients.

  8. Alfred Adler, pioneer in prevention of mental disorders.

    1990-09-01

    Alfred Adler (1870-1937) one of the four original members of what was to become the Vienna Psychoanalytic Society, was the first to accept a humanistic-educational model of man in contrast to Freud's medical model of man. This was in line with his deep involvement with prevention; in fact his original interest was in medical prevention. The present paper describes how his work touched on all the points of the contemporary field of psychological prevention. He developed a personality theory most suitable for application in prevention, education and brief psychotherapy. He identified various categories of children at risk. He advocated the right to abortion partly to prevent the birth of a child severely at risk by being unwanted. He considered the then existing dominance of the male sex to be damaging to both sexes. He engaged in practical prevention work by addressing general audiences and especially teachers and by the establishment of and participation in Educational Counseling Centers. He felt that the honest psychologist for reasons of prevention is bound to social advocacy, and that a true psychology of mental health merges into a corresponding world philosophy. These points are fully documented with quotations and references.

    A new parameterization of the Wegener-Bergeron-Findeisen (WBF) process has been developed, and implemented in the general circulation model CAM-Oslo. The new parameterization scheme has important implications for the process of phase transition in mixed-phase clouds. The new treatment of the WBF process replaces a previous formulation, in which the onset of the WBF effect depended on a threshold value of the mixing ratio of cloud ice. As no observational guidance for such a threshold value exists, the previous treatment added uncertainty to estimates of aerosol effects on mixed-phase clouds. The new scheme takes subgrid variability into account when simulating the WBF process, allowing for smoother phase transitions in mixed-phase clouds compared to the previous approach. The new parameterization yields a model state which gives reasonable agreement with observed quantities, allowing for calculations of aerosol effects on mixed-phase clouds involving a reduced number of tunable parameters. Furthermore, we find a significant sensitivity to perturbations in ice nuclei concentrations with the new parameterization, which leads to a reversal of the traditional cloud lifetime effect.

    The objective of this article is to provide a portrait of prefrontal lobotomy performed at the Royal Prince Alfred Hospital, Sydney by the Head of Neurosurgery Dr Rex Money and to describe Dr Money's role in the promotion of psychosurgery in Sydney. We draw attention to an oral presentation by Dr Rex Money in 1951, a journal article written by Money, archival information held at the Royal Prince Alfred Hospital, including Dr Money's accounts of his travels and his reports regarding neurosurgery - both internationally and in Australia. Dr Rex Money performed a series of 13 prefrontal lobotomies between 1945 and 1951, and presented the theoretical basis for his series, his operative procedures and the outcomes at the annual meeting of its medical officers' association. Notwithstanding various deficiencies in his clinical research, Money's descriptions give a relatively comprehensive account of one of the first series of prefrontal lobotomies performed in Australia. The current article also describes Dr Money's contributions to the promotion of psychosurgery in Sydney, and illustrates the participation of a senior neurosurgeon and of a major Sydney teaching hospital during the psychosurgery saga. © The Royal Australian and New Zealand College of Psychiatrists 2016.

    The development of organic and physical chemistry as specialist fields, during the middle and end of the 19th century respectively, left inorganic behind as a decidedly less highly regarded subfield of chemistry. Despite Alfred Werner's groundbreaking studies of coordination chemistry in the early 20th century, that inferior status remained in place - particularly in the US - until the 1950s, when the beginnings of a resurgence that eventually restored its parity with the other subfields can be clearly observed. This paper explores the extent to which Werner's heritage - both direct, in the form of academic descendants, and indirect - contributed to those advances.

    Contrary to what happened in many other countries in the 1930s and 1940s, Alfred Wegener's theory of continental drift was not generally rejected in Nazi Germany, although several leading German geologists of the time did not accept it. It was actually presented as the modern view of Earth history in books and magazine articles aimed at the general public. Although outlandish geological theories such as Hörbiger's Welteislehre were favoured by some Nazi dignitaries, they were not widely accepted in scientific circles. On the other hand, continental drift received official support under the Third Reich, at a time when it was ignored or ridiculed by most earth scientists outside Germany.

    Conventional wisdom has had it that the naturalist Alfred Russel Wallace and his colleague Henry Walter Bates journeyed to the Amazon in 1848 with two intentions in mind: to collect natural history specimens, and to consider evidential materials that might reveal the causal basis of organic evolution. This understanding has been questioned recently by the historian John van Wyhe, who points out that with regard to the second matter, at least, there appears to be no evidence of a "smoking gun" variety proving it so. In the present essay the circumstances of Wallace's interest in the matter are reviewed, and van Wyhe is taken to task with alternate explanations for the facts he introduces in his argument. The conclusion is that Wallace almost certainly did have the second objective in mind when he left for both the Amazon, and the Far East.

    Development along the western beachfront of Port Alfred, which is situated along a sandy shoreline, increased markedly in the 1960s as the coastal town became a popular holiday resort. This development included the removal of coastal vegetation, which resulted in the destabilization of dunes and migration of sand westerly onto the road, West Beach parking lot, and lawns of the cabanas. Sand traps were constructed to collect sand blowing across the dunes over set periods, and the net sand movement along the mobile dune belt was calculated using Hunter's equation. The dunes show an easterly movement of sand at a rate of 3.5 m/yr, which is comparable with figures recorded along other areas of this coastline. Considering the wind regime and amount of sand movement along this coast, it is inappropriate to clear vegetation and develop within the dune region.

    2000-11-01

    The search for a modern, humane method of criminal execution was triggered by a freak accident which occurred in Buffalo, New York in 1881. Dr. Alfred P. Southwick (a former steam-boat engineer, noted dentist and dental educator) happened to witness an intoxicated man die after he inadvertently touched a live generator terminal. Southwick's initial reaction was shock. Later, as he pondered this tragic event, he concluded that electrocution was, at least, a quick and seemingly painless way to depart from this earth. As his thoughts turned to common methods of capital punishment, Alfred concluded that death by electrocution could become a more humane alternative, as compared with the more grisly methods (e.g., hanging, beheading by guillotine, garroting, suffocation and flaying). Working through the governor of New York and the state legislature, Southwick originated and successfully promoted the passage of laws which mandated electrical executions in New York and in approximately 20 other states. During 1888-1889, Southwick served on the state's three-person Electrical Death Commission, a group who reported that electrical execution was superior to all other methods. On January 1, 1889, the world's first electrical execution law went into effect. On August 6, 1890, William Francis Kemmler, who had murdered his mistress, was the first person to die in the electric chair. However, this public event became an amateurish spectacle: the initial surge of current did not cause Kemmler's immediate death and a second jolt was needed. Those who witnessed this bungled execution were stunned. Graphic and detailed criticism from both the press and the general public ran high. However, Dr. Southwick vigorously continued to support and finally achieve his goal--to humanize capital punishment through the legal use of electrical execution.

    One century ago, Constantin S. Mereschkowsky introduced the symbiogenesis theory for the origin of chloroplasts from ancient cyanobacteria which was later supplemented by Ivan E. Wallin's proposal that mitochondria evolved from once free-living bacteria. Today, this Mereschkowsky-Wallin principle of symbiogenesis, which is also known as the serial primary endosymbiosis theory, explains the evolutionary origin of eukaryotic cells and hence the emergence of all eukaryotes (protists, fungi, animals and plants). In 1858, the concept of natural selection was described independently by Charles Darwin and Alfred R. Wallace. In the same year, Antonio Snider-Pellegrini proposed the idea of shifting continents, which was later expanded by Alfred Wegener, who published his theory of continental drift eight decades ago. Today, directional selection is accepted as the major cause of adaptive evolution within natural populations of micro- and macro-organisms and the theory of the dynamic Earth (plate tectonics) is well supported. In this article, I combine the processes and principles of symbiogenesis, natural selection and the dynamic Earth and propose an integrative 'synade-model' of macroevolution which takes into account organisms from all five Kingdoms of life.

    Wegener's granulomatosis (WG) is a systemic vasculitis that can affect a variety of organs including ear, nose and throat, lungs and kidneys. However WG is unusual in the pituitary and rare in the central nervous system. A 56-year-old male with likely WG presented with polyuria and polydipsia despite six months of conservative medical management. MRI scanning revealed an enlarging heterogeneously enhancing pituitary gland. Following endoscopic transsphenoidal pituitary biopsy and debulking, final tissue pathology was diagnostic for WG in the pituitary gland. Diagnosis remains difficult but most patients present with central diabetes insipidus (CDI) as well as varying degrees of hypopituitarism on a background of disease activity in other organs. Clinical judgment needs to balance the need for invasive surgical tissue diagnosis with increasing immunosuppressive therapy. It is important to consider this rare complication of WG to ensure timely diagnosis and management. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

    Polyangiitis overlap syndrome is defined as systemic vasculitis that cannot be classified into one of the well-defined vasculitic syndromes. In this report, a female patient who presented with vasculitis-like and asthmatic symptoms was diagnosed as having polyangiitis overlap syndrome of granulomatosis with polyangiitis (GPA; formerly known as Wegener's granulomatosis) and eosinophilic granulomatosis with polyangiitis (EGPA; formerly known as Churg-Strauss syndrome). The patient fulfilled the American College of Rheumatology diagnostic criteria for GPA and EGPA. She was successfully treated with immunosuppressants and steroids and has been in remission for 20 months. It is important to establish a proper diagnosis and introduce an appropriate treatment modality in patients with this rare and serious pathology to prevent irreversible organ damage.

    Alfred E. Mann's vision is to create organizations that will help medical innovations born in academic environments evolve into commercially fit solutions, without the risk of being abandoned under the financial pressures early stage start-ups often experience. In 1998, Mann worked with Stephen Sample, president of USC, to create the first AMI for Biomedical Engineering, an organization fueled by an endowment valued at approximately US$160 million today. Technology-acceleration centers come in different flavors. AMI USC's recipe has evolved since its creation, with edits that incorporate lessons learned and improvements brought by its expanding network of talented resource people. Its 15-member staff, consisting of three-fourths industry professionals, includes seasoned generalists and specialists in medical technology commercialization. Although the support varies with each invention, some recurring ingredients weave into the AMI approach to accelerating medical innovation.

    2017-05-01

    Despite intensified research efforts on the history of anatomy during National Socialism (NS), many aspects of this story still need further investigation. This study explores the life, work and politics of Alfred Pischinger, Chairman of the Institute for Embryology and Histology in Graz from 1936 to 1945, and in Vienna from 1958 to 1970, and is an addition to previous reports on careers in anatomy continuing through the Third Reich to the postwar period. Pischinger was an illegal NSDAP member in Austria, joined the SA in 1938, served as expert in racial hygiene, and as judge on the Genetic Health High Court of Graz. His research focus was histochemistry, but he became part of a scientific network at the University of Graz, which from 1939 on experimented on the bodies of pregnant women and their fetuses under the leadership of gynecologist Karl Ehrhardt. The researchers were among the many who took actively part in the complete exploitation and physical destruction of those considered to be "the enemy" by the NS regime. After the war, Pischinger received publicity for his work on the "scientific basis" of alternative and holistic approaches of medicine. His NS past and fetal experiments seem to have vanished from public knowledge. As systematic studies of the influence of the NS period on postwar medical education and the science of anatomy itself are still missing, this critical investigation of Alfred Pischinger's life within the relevant historic background aims to contribute to this body of knowledge.

  4. Alfred Binet and the Concept of Heterogeneous Orders†

    2012-01-01

    In a comment, hitherto unremarked upon, Alfred Binet, well known for constructing the first intelligence scale, claimed that his scale did not measure intelligence, but only enabled classification with respect to a hierarchy of intellectual qualities. Attempting to understand the reasoning behind this comment leads to an historical excursion, beginning with the ancient mathematician, Euclid and ending with the modern French philosopher, Henri Bergson. As Euclid explained (Heath, 1908), magnitudes constituting a given quantitative attribute are all of the same kind (i.e., homogeneous), but his criterion covered only extensive magnitudes. Duns Scotus (Cross, 1998) included intensive magnitudes by considering differences, which raised the possibility (later considered by Sutherland, 2004) of ordered attributes with heterogeneous differences between degrees (“heterogeneous orders”). Of necessity, such attributes are non-measurable. Subsequently, this became a basis for the “quantity objection” to psychological measurement, as developed first by Tannery (1875a,b) and then by Bergson (1889). It follows that for attributes investigated in science, there are three structural possibilities: (1) classificatory attributes (with heterogeneous differences between categories); (2) heterogeneous orders (with heterogeneous differences between degrees); and (3) quantitative attributes (with thoroughly homogeneous differences between magnitudes). Measurement is possible only with attributes of kind (3) and, as far as we know, psychological attributes are exclusively of kinds (1) or (2). However, contrary to the known facts, psychometricians, for their own special reasons insist that test scores provide measurements. PMID:22912619

It follows that for attributes investigated in science, there are three structural possibilities: (1) classificatory attributes (with heterogeneous differences between categories); (2) heterogeneous orders (with heterogeneous differences between degrees); and (3) quantitative attributes (with thoroughly homogeneous differences between magnitudes). Measurement is possible only with attributes of kind (3) and, as far as we know, psychological attributes are exclusively of kinds (1) or (2). However, contrary to the known facts, psychometricians, for their own special reasons insist that test scores provide measurements.

    Starting from a passage in the Dora case history where Freud suggests some differences between a literary and a clinical narrative of female homosexuality, this paper presents examples which he might have had in mind. Besides Balzac's "La fille aux yeux d'or" (1834/35) it is in particular Alfred v. Berger's novella "Die Italienerin [The Italian woman]" (1904) which may have served as a model and counterpoint to the literary strategies used in Freud's case history. Freud had a relationship of long standing with Berger. This newly discovered source may provide a clue for the date at which Freud finalized the Dora manscript which he had held back for years.

    ANCA were described in 1982 as sensitive and specific markers for active Wegener's granulomatosis (WG). We analysed the results of ANCA test performed in 298 patients hospitalized in Institute of Tuberculosis and Lung Diseases in the period 1990-1998 because of different symptoms and syndromes of respiratory system which could be symptoms of WG. Presence of c-ANCA, p-ANCA and other not well defined types of ANCA in the titer greater than 1:40 in the serum was regarded as positive result of test. We found it in 60 patients. In 47 WG pts ANCA were present in 40 of 42 pts with active disease and 1 of 5 in remission. Further 19 positive results were found in a group of 251 patients with other diseases: 1 of 4 pts with Churg-Strauss syndrome, 1 of 2 with pulmonary renal syndrome, 5 of 28 with connective tissue diseases, 1 of 21 with tuberculosis, 1 of 23 with sarcoidosis, 1 of 6 with histiocytosis, 3 of 11 with hypersensitivity pneumonitis, 1 (lymphoma) of 34 with neoplasms, 1 of 20 with pulmonary fibrosis, 1 of 8 with cardiac failure, 1 of 5 with pleural fluid, 1 of 10 pneumoconiosis and toxic reactions (after furagin), 1 of 6 with BOOP. Sensitivity of ANCA test in our material is 87%, specificity = 95%, and positive prevalence accuracy is 68%. It means that 32% of the patients with positive results could be inappropriate treated as WG. ANCA test could be not used as a screening test. Results of ANCA test alone cannot be used as basis for treatment. ANCA test is a helpful tool in diagnosing of WG.

    Prof. Kohn (1867-1959) was the head of the Institute of Histology at the Medical Faculty of German University in Prague for 26 years. In 2007 we commemorated his 140th birthday, and 2009 we will remember the 50th anniversary of his death. He entered the history of medicine by discovery of nature and origin of parathyroid glands and by pioneer research into chromaffin cells and sympathetic paraganglia. Kohn's papers on the pituitary, interstitial cells of testes, and ovaries are also related to endocrinology. All his studies are based on descriptive and comparative histological and embryological observations. Kohn was twice the dean of German Medical Faculty, and a member or honorary member of many important scientific societies. He was repeatedly nominated for Nobel Prize for physiology and medicine. For his Jewish origin he was expelled from Deutsche Gesellschaft der Wissenschaften und Künste für die Tschechoslowakische Republik in 1939 and transported to Terezin ghetto in 1943. After the war he lived in Prague. On the occasion of his 90th birthday he was elected honorary president of Anatomische Gesellschaft and awarded by the Czechoslovak Order of Labour. Alfred Kohn died in 1959. He was one of the outstanding personalities that Prague gave to the world of science.

    2010-03-01

    This essay tells the story of early French ethology--"the science dealing with the habits of living beings and their relations, both with each other and with the cosmic environment." The driving force behind this "ethological movement" was the biologist Alfred Giard (1846-1908). The essay discusses how the ethological viewpoint of Giard and his pupils developed in a period in which the current disciplines of field biology were not yet crystallized. It also shows how concepts and research interests could travel within Giard's network from one working context to another, even from one discipline to another. By studying this traveling process, the essay reveals that, unlike the modern ethology of Konrad Lorenz and Niko Tinbergen, Giard's ethology was not a discipline at all but, rather, a scientific attitude. This scientific attitude triggered a reappraisal of fieldwork, but at the same time Giard's ethology was never limited to the field alone. It also found its way to the laboratory, the museum, and the zoo.

    Alfred Russel Wallace (1823-1913), naturalist and explorer of South America and the Malay Archipelago, secured his place in history by independently discovering the theory of natural selection. His letter outlining the theory was sent from Ternate in eastern Indonesia and received at Down House, according to Charles Darwin (1809-82), on June 18, 1858, prompting the now-famed evolutionist to rush his languishing manuscript to press. Wallace's contributions to evolutionary biology, biogeography, and anthropology are well known, but his medical views have received far less attention. Within the context of a strident populist antivaccination movement and an ominous elitist eugenics campaign, Wallace took his stand, which revealed itself in a libertarianism that defended traditional socialist constituencies (the working poor, the lumpenproletariat, and feminist reformers) against state-mandated medical interventions. Rather than viewing Wallace as a heterodox contrarian, this article argues that his positions were logical outgrowths of his medical libertarianism and evolutionary and social theories. © The Author 2013.

  12. The Challenges of Developing a Framework for Global Water Cycle Monitoring and Prediction (Alfred Wegener Medal Lecture)

    NASA Astrophysics Data System (ADS)

    Wood, Eric F.

    2014-05-01

    The Global Earth Observation System of Systems (GEOSS) Water Strategy ("From Observations to Decisions") recognizes that "water is essential for ensuring food and energy security, for facilitating poverty reduction and health security, and for the maintenance of ecosystems and biodiversity", and that water cycle data and observations are critical for improved water management and water security - especially in less developed regions. The GEOSS Water Strategy has articulated a number of goals for improved water management, including flood and drought preparedness, that include: (i) facilitating the use of Earth Observations for water cycle observations; (ii) facilitating the acquisition, processing, and distribution of data products needed for effective management; (iii) providing expertise, information systems, and datasets to the global, regional, and national water communities. There are several challenges that must be met to advance our capability to provide near real-time water cycle monitoring, early warning of hydrological hazards (floods and droughts) and risk assessment under climate change, regionally and globally. Current approaches to monitoring and predicting hydrological hazards are limited in many parts of the world, and especially in developing countries where national capacity is limited and monitoring networks are inadequate. This presentation describes the developments at Princeton University towards a seamless monitoring and prediction framework at all time scales that allows for consistent assessment of water variability from historic to current conditions, and from seasonal and decadal predictions to climate change projections. At the center of the framework is an experimental, global water cycle monitoring and seasonal forecast system that has evolved out of regional and continental systems for the US and Africa. The system is based on land surface hydrological modeling that is driven by satellite remote sensing precipitation to predict current hydrological conditions, flood potential and the state of drought. Seasonal climate model forecasts are downscaled and bias-corrected to drive the land surface model to provide hydrological forecasts and drought products out 6-9 months. The system relies on historic reconstructions of water variability over the 20th century, which forms the background climatology to which current conditions can be assessed. Future changes in water availability and drought risk are quantified based on bias-corrected and downscaled climate model projections that are used to drive the land surface models. For regions with lack of on-the-ground data we are field-testing low-cost environmental sensors and along with new satellite products for terrestrial hydrology and vegetation, integrating these into the system for improved monitoring and prediction. At every step there are scientific challenges whose solutions are only partially being solved. In addition there are challenges in delivering such systems as "climate services", especially to societies with low technical capacity such as rural agriculturalists in sub-Saharan Africa, but whose needs for such information are great. We provide an overview of the system and some examples of real-world applications to flood and drought events, with a focus on Africa.

    The co-discoverer of natural selection, Alfred Russel Wallace, found himself deeply embroiled in a range of controversies surrounding the relationship between science and spiritualism. At the heart of these controversies lay a crisis of evidence in cases of delusion or imposture. He had the chance to observe the many epistemic impasses brought about by this crisis while participating in the trial of the American medium Henry Slade, and through his exchanges with the physiologist William Benjamin Carpenter and the psychical researcher Frederic Myers. These contexts help to explain the increasing value that Wallace placed on the evidence of spirit photography. He hoped that it could simultaneously break these impasses, while answering once and for all the interconnected questions of the unity of the psyche and the reliability of human observation.

    Alfred Nobel was one of the most successful chemists, inventors, entrepreneurs, and businessmen of the late nineteenth century. In a decision later in life, he rewrote his will to leave virtually all his fortune to establish prizes for persons of any nationality who made the most compelling achievement for the benefit of mankind in the fields of chemistry, physics, physiology or medicine, literature, and peace among nations. The prizes were first awarded in 1901, five years after his death. In considering his choice of prizes, it may be pertinent that he used the principles of chemistry and physics in his inventions and he had a lifelong devotion to science, he suffered and died from severe coronary and cerebral atherosclerosis, and he was a bibliophile, an author, and mingled with the literati of Paris. His interest in harmony among nations may have derived from the effects of the applications of his inventions in warfare (“merchant of death”) and his friendship with a leader in the movement to bring peace to nations of Europe. After some controversy, including Nobel’s citizenship, the mechanisms to choose the laureates and make four of the awards were developed by a foundation established in Stockholm; the choice of the laureate for promoting harmony among nations was assigned to the Norwegian Storting, another controversy. The Nobel Prizes after 115 years remain the most prestigious of awards.

    One hundred and fifty years after Alfred Wallace studied the geographical variation and species diversity of butterflies in the Indomalayan-Australasian Archipelago, the processes responsible for their biogeographical pattern remain equivocal. We analysed the macroevolutionary mechanisms accounting for the temporal and geographical diversification of the charismatic birdwing butterflies (Papilionidae), a major focus of Wallace's pioneering work. Bayesian phylogenetics and dating analyses of the birdwings were conducted using mitochondrial and nuclear genes. The combination of maximum likelihood analyses to estimate biogeographical history and diversification rates reveals that diversity-dependence processes drove the radiation of birdwings, and that speciation was often associated with founder-events colonizing new islands, especially in Wallacea. Palaeo-environment diversification models also suggest that high extinction rates occurred during periods of elevated sea level and global warming. We demonstrated a pattern of spatio-temporal habitat dynamics that continuously created or erased habitats suitable for birdwing biodiversity. Since birdwings were extinction-prone during the Miocene (warmer temperatures and elevated sea levels), the cooling period after the mid-Miocene climatic optimum fostered birdwing diversification due to the release of extinction. This also suggests that current global changes may represent a serious conservation threat to this flagship group.

    Many in dental education are unfamiliar with the professional life and thought of Dr. Alfred Owre, a distinguished though controversial dental educator in the early twentieth century. Owre served as dean of dentistry at both the University of Minnesota, 1905-27, and Columbia University, 1927-33. He was also a member of the Carnegie Foundation's commission that developed the report Dental Education in the United States and Canada, written by Dr. William J. Gies. Owre was a controversial leader due to his creative and original ideas that challenged dental education and the profession. His assessment and critique of the problems of dental education in his era can readily be applied to contemporary dental education and the profession, just as his vision for transformative change resonates with ideas that continue to be advocated by some individuals today. This article also documents his tumultuous relationship with Gies.

His passion for mineralogy, displayed since his youngest years, leads him to frequent scientists specialized in the earth's science, amongst who is Ferdinand Fouque, from the College of France (College de France), whom he used to accompany in his travels through the world between 1888 - the year when he parted from his pharmacy - and 1902. This very year, the eight of may, the terrifying eruption of the montagne Pelee on the isle of la Martinique annihilated in few minutes the town and the port of Saint-Pierre, leaving only two survivors, He sejourned there a second time, in august 1902 after the second eruption. A. Lacroix explained, for the first time, phenomena he designated as nuees ardentes. His knowledge in volcanology and mineralogy made him an expert who has been solicitated to observe various volcanos through out the world. Amongst his principal writings are the treaty of mineralogy (5 vol.), the 2 volumes of his conclusions about his observations of the montagne Pelee and one about the Piton de la Fournaise, to which must be added more than 650 notes and communications. Great officer of the Legion d'Honneur, the chemist Alfred Lacroix, professor at the Museum of natural history since the first of april 1893, carried on the function of perpetual secretary of the Academy of Sciences during 34 years.

    We systematically investigated the effect of Wegener-Bergeron-Findeisen (WBF) process to black carbon (BC) simulation by a global 3D chemical transport model GEOS-Chem constrained by measurements of BC scavenging efficiencies, concentration in air, deposition fluxes, concentration in snow and washout ratios. Including effect of WBF process reduces the annual mean BC scavenging efficiencies (the ratio of BC in cloud droplets to total BC) at all altitudes by 43-76% in the Arctic. For mid latitude BC scavenging efficiencies decrease by 8-22%, 23-39%, and 41-50% in lower (0-2 km), middle (2-5 km) and upper troposphere (5-10 km), respectively. Simulated BC in air in the Arctic and at mid altitude (˜4 km) in mid latitude increases by ˜40%, and the discrepancy reduces from -65% to -30%. Simulated median BC in snow decreases from 25.7 to 22.4 ng g-1, by 15% in mid latitude and increases from 8.7 to 11.0 ng g-1, by 26% in the Arctic and the comparison with observations improves. The model overestimates washout ratios (ratio of BC in fresh snow/rain to BC in surface air) at most of the sites by up to a factor of 165. With effect of WBF process included, the discrepancy decreases to a factor of 72. The simulated BC burden increases from 0.22 to 0.35 mg m-2 yr-1 when effect of WBF process is included, partly explains the scaled up of BC burden in Bond et al., 2013. Moreover, burden above 5 km increases from 22% to 27% when WBF process is included, indicating a higher forcing efficiency. We also found that BC simulation is insensitive to the temperature criteria between mixed phase clouds and ice clouds. The simulated BC burden is the same when the temperature is set as -15° C and -25° C. This study also suggests that more observations are needed to better distinguish riming dominated and WBF dominated conditions and better parameterize BC scavenging efficiency under the two conditions.

    During the last century, three different ways of interpreting the tectonic evolution of the Gulf of Mexico and the Caribbean have been proposed, taking into account the Bailey Willis School of a permanent pre-Jurassic deep sea basin, the Edward Suess School of a subsided continental terrain, and the Alfred Wegener School of continental separation. The present investigation is concerned with an outline of an interpretation which follows that of Pindell and Dewey (1982). An attempt is made to point out ways in which the advanced hypotheses can be tested. The fit of Africa, North America, and South America is considered along with aspects of relative motion between North and South America since the early Jurasic. Attention is given to a framework for reconstructing Caribbean plate evolution, the evolution of the Caribbean, the plate boundary zones of the northern and southern Caribbean, and the active deformation of the Caribbean plate.

    2017-04-01

    Hydrologic science has undergone almost transformative changes over the past 50 years. Huge strides have been made in the transition from early empirical approaches to rigorous approaches based on the fluid mechanics of water movement on and below the land surface. However, further progress has been hampered by problems posed by the presence of heterogeneity, especially subsurface heterogeneity, at all scales. The inability to measure or map subsurface heterogeneity everywhere prevented further development of balance equations and associated closure relations at the scales of interest, and has led to the virtual impasse we are presently in, in terms of development of physically based models needed for hydrologic predictions. An alternative to the mapping of subsurface heterogeneity everywhere is a new earth system science view, which sees the heterogeneity as the end result of co-evolutionary hydrological, geomorphological, ecological and pedological processes, each operating at a different rate, which have helped to shape the landscapes that we see in nature, including the heterogeneity below that we do not see. The expectation is that instead of specifying exact details of the heterogeneity in our models, we can replace it, without loss of information, with the ecosystem function they perform. Guided by this new earth system science perspective, development of hydrologic science is now guided by altogether new questions and new approaches to address them, compared to the purely physical, fluid mechanics based approaches that we inherited from the past. In the emergent Anthropocene, the co-evolutionary view is expanded further to involve interactions and feedbacks with human-social processes as well. In this lecture, I will present key milestones in the transformation of hydrologic science from Engineering Hydrology to Earth System Science, and what this means for hydrologic observations, theory development and predictions.

    Macmillan, Malcolm

    2014-07-01

    In his pioneering cytoarchitectonic studies of the human brain, Alfred Walter Campbell identified two structurally different areas in the occipital lobes and assigned two different kinds of visual functions to them. The first area, the visuosensory, was essentially on the mesial surface of the calcarine fissure. It was the terminus of nervous impulses generated in the retina and was where simple visual sensations arose. The second area, the visuopsychic, which surrounded or invested the first, was where sensations were interpreted and elaborated into visual perceptions. I argue that Campbell's distinction between the two areas was the starting point for the eventual differentiation of areas V1-V5. After a brief outline of Campbell's early life and education in Australia and of his Scottish medical education and early work as a pathologist at the Lancashire County Lunatic Asylum at Rainhill near Liverpool, I summarise his work on the human brain. In describing the structures he identified in the occipital lobes, I analyse the similarities and differences between them and the related structures identified by Joseph Shaw Bolton. I conclude by proposing some reasons for how that work came to be overshadowed by the later studies of Brodmann and for the more general lack of recognition given Campbell and his work. Those reasons include the effect of the controversies precipitated by Campbell's alliance with Charles Sherrington over the functions of the sensory and motor cortices. Copyright © 2012 Elsevier Ltd.

    Neutrophils are the target of autoantibodies in Wegener's granulomatosis (WG). In this study, granulocyte function and surface marker expression were investigated in patients with WG. The oxidative burst in response to phorbol myristate acetate (PMA) was tested with granulocytes of 25 patients with histologically proven WG. A significantly diminished percentage of oxygen radical-producing cells was found in patients with active disease. Surface antigen expression of CD11b and LAM-1 was analysed on granulocytes of 20 patients with WG. Whereas the expression of CD11b was normal, surface expression of LAM-1 was decreased in nine cases with WG. The decrease of LAM-1 correlated with disease activity. Phagocytosis of Escherichia coli was tested in 10 patients with WG, and normal values were found in all cases. We conclude that down-regulation of LAM-1 may be a marker of disease activity in WG. The altered response to PMA may indicate functional changes in granulocyte reactivity due to autoantibody-induced damage of the granulocyte membrane. PMID:7512009

    Background: Diagnosis of active pulmonary and paranasal involvement in patients with Wegener's granulomatosis (WG) can be difficult. The diagnostic value of gallium-67 scintigraphy in WG is unclear. Objective: To evaluate the added diagnostic value of gallium-67 scintigraphy in patients with WG with suspected granulomatous inflammation in the paranasal and chest regions. Methods: Retrospectively, the diagnostic contribution of chest and head planar gallium scans in 40 episodes of suspected vasculitis disease activity in 28 patients with WG was evaluated. Scans were grouped into normal or increased uptake for each region. Histological proof or response to treatment was the "gold standard" for the presence of WG activity. Results: WG activity was confirmed in 8 (20%) episodes, with pulmonary locations in three, paranasal in four, and both in one (n=7 patients); all these gallium scans showed increased gallium uptake (sensitivity 100%). Gallium scans were negative for the pulmonary area in 23/36 scans (specificity 64%), and negative for paranasal activity in 13/16 scans (specificity 81%) in episodes without WG activity. Positive predictive value of WG activity for lungs and paranasal region was 24% and 63%, respectively, negative predictive value was 100% for both regions. False positive findings were caused by bacterial or viral infections. Conclusion: Gallium scans are clinically helpful as a negative scan virtually excludes active WG. Gallium scintigraphy of chest and nasal region has a high sensitivity for the detection of disease activity in WG. However, because of positive scans in cases of bacterial or viral infections, specificity was lower. PMID:12810430

  6. Thermal Models of the Ocean Floor: from Wegener to Cerro Prieto

    2017-12-01

    Wegener (1925) argued that hot rock could explain the shallower depths of ridges in the center of the Atlantic Ocean. Hess (1963) proposed that the intrusion of molten rock occurred at a world encircling mid-ocean ridge system. However, he accounted for the elevation of the ridges by the formation of serpentinite and thermal convection. Langseth et al. (1966) provided the major advance by using a 100 km thick plate to argue such a concept could not explain the depth, heat flow versus distance relations. They had the correct model but misinterpreted the data. Reformulating theoretically, McKenzie (1967) created the generally accepted thermal model for the ocean floor. Unfortunately, in attempting to match erroneously low heat flow data, he used a 50 km thick plate. Addition of the effect of water and the realization of the importance of advective flow, enabled various groups to create thermal plate models that accounted for the heat flow and depth age relations. From this came the understanding of hydrothermal circulation in the oceanic crust, the thermal boundary layer concept of the oceanic plate and the realization that all thermal models differed only in the way the different groups had chosen to analyze the data. During the past 40 years many have applied similar concepts to continental margins: (1) Measurement of subsidence of the Atlantic margin, continental stretching and a Time Temperature, Depth and Maturation analysis of continental basins have created the field of Basin Analysis; (2) Changes in heat flow at ocean continent boundaries have determined the position of the transition and (3) In attempting to examine the ocean continent transition process in the northernmost basin of the Gulf of California, Neumann et al (in press) observed conductive heat flow values greater than 0.75 Watts, at a depth of < 150 m, along a 10 km section of a profile across the southern extension of the Cerro Prieto fault. The magnitude of these values overwhelms local

Subsequently, Wallace published a series of papers on systematic ornithology, and discovered a new species on top of a volcano on Ternate, where he wrote, in 1858, his famous essay on natural selection. Based on this hands-on experience, and an analysis of an Archaeopteryx fossil, Wallace suggested that birds may have descended from dinosaurian ancestors. Here, we describe the "dinosaur-bird hypothesis" that originated with the work of Thomas H. Huxley (1825-1895). We present the strong evidence linking theropod dinosaurs to birds, and briefly outline the long and ongoing controversy around this concept. Dinosaurs preserving plumage, nesting sites and trace fossils provide overwhelming evidence for the dinosaurian origin of birds. Based on these recent findings of paleontological research, we conclude that extant birds indeed descended, with some modifications, from small, Mesozoic theropod dinosaurs. In the light of Wallace's view of bird origins, we critically evaluate recent opposing views to this idea, including Ernst Mayr's (1904-2005) arguments against the "dinosaur-bird hypothesis", and document that this famous ornithologist was not correct in his assessment of this important aspect of vertebrate evolution.

  8. Effects of Wegener-Bergeron-Findeisen Process on Global Black Carbon Distribution

    In mixed-phase clouds, the Wegener-Bergeron-Findeisen (WBF) process (ice crystals may grow while water drops evaporate, thereby releasing black carbon (BC) particles into the interstitial air) slows down wet scavenging of BC. Rimming (snowflakes fall and collect cloud water drops and the BC in them along their pathways), in contrast, results in more efficient wet scavenging. We systematically investigate the effects of WBF on BC scavenging efficiency, surface BCair, deposition flux, concentration in snow, and washout ratio using a global 3D chemical transport model. We differentiate riming- vs WBF-dominated in-cloud scavenging based on liquid water content and temperature. Specifically, we relate WBF to either temperature or ice mass fraction in mixed-phase clouds. We find that at Jungfraujoch, Switzerland and Abisko, Sweden, where WBF dominates, the discrepancies of simulated BC scavenging efficiency and washout ratio are significantly reduced (from a factor of 3 to 10% and from a factor of 4-5 to a factor of two). However, at Zeppelin, Norway, where riming dominates, simulation of BC scavenging efficiency, BCair, and washout ratio become worse (relative to observations) when WBF is included. There is thus an urgent need for extensive observations to distinguish and characterize riming- versus WBF-dominated aerosol scavenging in mixed-phase clouds and the associated BC scavenging efficiency. We find the reduction resulting from WBF to global BC scavenging efficiency varies substantially, from 8% in the tropics to 76% in the Arctic. The resulting annual mean BCair increases by up to 156% at high altitudes and at northern high latitudes. Overall, WBF halves the model-observation discrepancy (from -65% to -30%) of BCair across North America, Europe, China and the Arctic. Globally WBF increases BC burden from 0.22 to 0.29-0.35 mg m-2 yr-1, which partially explains the gap between observed and previous model simulated BC burdens over land (Bond et al., 2013). In

    To date, historians of psychology have largely ignored the role of academic publishing and the editorial policies of the late nineteenth century. This paper analyzes the role played by academic publishing in the history of psychology in the specific case of France, a country that provides a very interesting and unique model. Up until the middle of the 1890s, there was no collection specifically dedicated to psychology. Alfred Binet was the first to found, in 1897, a collection of works specifically dedicated to scientific psychology. He chose to work with Reinwald-Schleicher. However, Binet was soon confronted with (1) competition from other French publishing houses, and (2) Schleicher's management and editorial problems that were to sound the death knell for Binet's emerging editorial ambitions. The intention of this paper is to encourage the efforts of the pioneers of modern psychology to have their work published and disseminated. © 2015 Wiley Periodicals, Inc.

    The demand for high-quality atmospheric data records, which are applicable in climate studies, is undisputed. Using such records requires knowledge of the quality and the specific characteristics of all contained data sources. The latest version of the Wegener Center (WEGC) multi-satellite Global Positioning System (GPS) radio occultation (RO) record, OPSv5.6, provides globally distributed upper-air satellite data of high quality, usable for climate and other high-accuracy applications. The GPS RO technique has been deployed in several satellite missions since 2001. Consistency among data from these missions is essential to create a homogeneous long-term multi-satellite climate record. In order to enable a qualified usage of the WEGC OPSv5.6 data set we performed a detailed analysis of satellite-dependent quality aspects from 2001 to 2017. We present the impact of the OPSv5.6 quality control on the processed data and reveal time-dependent and satellite-specific quality characteristics. The highest quality data are found for MetOp (Meteorological Operational satellite) and GRACE (Gravity Recovery and Climate Experiment). Data from FORMOSAT-3/COSMIC (Formosa Satellite mission-3/Constellation Observing System for Meteorology, Ionosphere, and Climate) are also of high quality. However, comparatively large day-to-day variations and satellite-dependent irregularities need to be taken into account when using these data. We validate the consistency among the various satellite missions by calculating monthly mean temperature deviations from the multi-satellite mean, including a correction for the different sampling characteristics. The results are highly consistent in the altitude range from 8 to 25 km, with mean temperature deviations less than 0.1 K. At higher altitudes the OPSv5.6 RO temperature record is increasingly influenced by the characteristics of the bending angle initialization, with the amount of impact depending on the receiver quality.

    The British naturalist Alfred Russel Wallace (1823-1913), who had to leave school aged 14 and never attended university, did extensive fieldwork, first in the Amazon River basin (1848-1852) and then in Southeast Asia (1854-1862). Based on this experience, and after reading the corresponding scientific literature, Wallace postulated that species were not created, but are modified descendants of pre-existing varieties (Sarawak Law paper, 1855). Evolution is brought about by a struggle for existence via natural selection, which results in the adaptation of those individuals in variable populations who survive and reproduce (Ternate essay, 1858). In his monograph Darwinism (1889), and in subsequent publications, Wallace extended the contents of Darwin's Origin of Species (1859) into the Neo-Darwinian theory of biological evolution, with reference to the work of August Weismann (1834-1914). Wallace also became the (co)-founder of biogeography, biodiversity research, astrobiology and evolutionary anthropology. Moreover, he envisioned what was later called the anthropocene (i.e., the age of human environmental destructiveness). However, since Wallace believed in atheistic spiritualism and mixed up scientific facts and supernatural speculations in some of his writings, he remains a controversial figure in the history of biology.

    To investigate the operating characteristics of the American College of Rheumatology (ACR) traditional format criteria for Wegener's granulomatosis (WG), the Sørensen criteria for WG and microscopic polyangiitis (MPA), and the Chapel Hill nomenclature for WG and MPA. Further, to develop and validate improved criteria for distinguishing WG from MPA by an artificial neural network (ANN) and by traditional approaches [classification tree (CT), logistic regression (LR)]. All criteria were applied to 240 patients with WG and 78 patients with MPA recruited by a multicenter study. To generate new classification criteria (ANN, CT, LR), 23 clinical measurements were assessed. Validation was performed by applying the same approaches to an independent monocenter cohort of 46 patients with WG and 21 patients with MPA. A total of 70.8% of the patients with WG and 7.7% of the patients with MPA from the multicenter cohort fulfilled the ACR criteria for WG (accuracy 76.1%). The accuracy of the Chapel Hill criteria for WG and MPA was only 35.0% and 55.3% (Sørensen criteria: 67.2% and 92.4%). In contrast, the ANN and CT achieved an accuracy of 94.3%, based on 4 measurements (involvement of nose, sinus, ear, and pulmonary nodules), all associated with WG. LR led to an accuracy of 92.8%. Inclusion of antineutrophil cytoplasmic antibodies did not improve the allocation. Validation of methods resulted in accuracy of 91.0% (ANN and CT) and 88.1% (LR). The ACR, Sørensen, and Chapel Hill criteria did not reliably separate WG from MPA. In contrast, an appropriately trained ANN and a CT differentiated between these disorders and performed better than LR.

    Objective Assess a generic measure of health-related quality of life (HRQOL) as an outcome measure in granulomatosis with polyangiitis (Wegener's, GPA) Methods Subjects were participants in the Wegener’s Granulomatosis Etanercept Trial (WGET) or the Vasculitis Clinical Research Consortium Longitudinal Study (VCRC-LS). HRQOL was assessed with the Short Form 36 Health Survey (SF-36) that includes physical and mental component summary scores (PCS and MCS). Disease activity was assessed with the Birmingham Vasculitis Activity Score for Wegener’s Granulomatosis (BVAS/WG). Results Data from 180 subjects in the WGET (median follow-up = 2.3 years, mean number of visits = 10) and 237 subjects in the VCRC-LS (median follow-up = 2.0 years, mean number of visits = 8) were analyzed. One unit increase in BVAS/WG corresponded to a 1.15 unit (95%CI: 1.02; 1.29) decrease in PCS and a 0.93 (95%CI: 0.78; 1.07) decrease in MCS in the WGET and by 1.16 for PCS (95%CI: 0.94; 1.39) and 0.79 for MCS (95%CI: 0.51; 1.39) in the VCRC-LS. In both arms of the WGET study, SF-36 measures improved rapidly during the first 6 weeks of treatment followed by gradual improvement among patients achieving sustained remission (0.5 improvement in PCS per three months), but worsened slightly (0.03 decrease in PCS per three months) among patients not achieving sustained remission (p = 0.005). Conclusion HRQOL, as measured by SF-36, is reduced among patients with GPA. SF-36 measures are modestly associated with other disease outcomes and discriminate between disease states of importance in GPA. PMID:21954229

    It took half a century for Wegener's continental drift theory to be accepted as a fundamental element of the plate tectonic theory. Another half a century on, we are still unsure of the driving mechanism for plate tectonics: is it dominated by thermal convection, gravitational forces, or by a combination of mechanisms? Nonetheless, breakthroughs in the past decades put us in a position to make a major stride in answering this question. These include: (1) widely accepted cyclic occurrences of supercontinent assembly and break-up (whereas random occurrence of supercontinents was an equal possibility in the 1990s); (2) the discovery of two equatorial and antipodal large low seismic velocity provinces (LLSVPs) that dominate the lower mantle and appear to have been the base for almost all mantle plumes since at the Mesozoic, and of subduction of oceanic slabs all the way to the core-mantle boundary, which together suggesting whole-mantle convection; (3) the recognition of true polar wander (TPW) as an important process in Earth history, likely reflecting Earth's major internal mass redistribution events; and (4) rapidly enhancing computer modelling power enabling us to simulate all aspect of Earth's dynamic inner working. Many new yet often controversial ideas have been proposed, such a possible coupling in time (with an offset) and space between supercontinent cycle and superplume (LLSVP) events which oppose to the idea of static and long-lived LLSVPs, and the orthoversion v.s. introversion or extroversion models for supercontinent transition. To fully utilise these advances as well as the rapidly expanding global geoscience databases to address the question of how Earth works, an UNESCO-IUGS sponsored IGCP project No. 648 was formed to coordinate a global cross-disciplinary effort. We aim to achieve a better understanding of the supercontinent cycle, and examine the relationship between supercontinent cycle and global plume events. We will establish a series of global

    A unfavourable notice written by industrial magnate Alfred Krupp (1812-1887) has been discovered on the posterior cover sheet of the first volume of the monumental series Fauna und Flora des Golfes von Neapel, edited by the Zoological Station at Naples (1880) Krupp's handwritten statement affords the opportunity to discuss in more detail the intricate relationship between the founder of the first marine biology station, Anton Dohrn (1840-1909), and the owner of the greatest steel factory in Europe, the Krupp-family at Essen. Although Anton Dohrn did not know about Krupp's disapproving comment he had a fine unerring instinct for the mentality of his negotiating partner, whose way of thinking rather aimed at the practical success and completion of armament factory, preventing thus a the serious rapprochement between the two personalities. Even when the Krupp-heir, Friedrich Alfred Krupp, later devoted to questions about marine biology in his new built house at Capri, and was willing to support the Zoological Station with high sponsoring, Anton Dohrn maintained a reserved attitude towards the Krupp's offer to support the marine research financially. Likewise, he remained unimpressed, when the steel magnate was shook by the smear campaign in Capri that ultimately led to Krupp's death in November 1902.

    James Alfred Van Allen, world-renowned space scientist, died 9 August 2006 at the age of ninety-one. He succumbed to heart failure after a ten-week period of declining health. Van Allen served for his entire sixty-seven-year professional career as an amazingly productive researcher, space science spokesman, inspired teacher, and valued colleague. The realization by him and his associates that charged particles are trapped by the Earth's magnetic field began a whole new field of research, magnetospheric physics. Following that initial discovery, he and his associates quickly extended their observations, first to the inner planets, and then to the rest of the planets and beyond. During his tenure at Iowa, he and his group flew instruments on more than sixty successful Earth satellites and planetary spacecraft, including the first missions to the planets Venus, Mars, Jupiter, Saturn, Uranus, and Neptune. Van Allen's lifetime publication list numbers more than 275, of which many are widely-cited, seminal papers. He was the sole author of more than 125 of those papers. Beyond the research laboratory, Van Allen worked energetically throughout his career in establishing space research as a new branch of human inquiry. He was among the most sought-after as a committee member and adviser, working at the highest levels of government, including the White House and Congress, and at all levels of the national and international research establishments. Many presentations in the non-scientific arena helped to bring the exciting discoveries and challenges of space research to the attention of the general public. James Van Allen (Van to his many friends and colleagues) was born on 7 September 1914 on a small farm near Mount Pleasant, Iowa, the second of four sons of Alfred Morris Van Allen and Alma Olney Van Allen. After high school in Mount Pleasant, he entered Iowa Wesleyan College, majoring in physics and graduating summa cum laude. While there, he was introduced to geophysics

    Both biochar application and mycorrhizal inoculation have been proposed to improve plant growth and alter bioaccumulation of toxic metals. A greenhouse pot trial was conducted to investigate growth and Cd accumulation of upland kangkong (Ipomoea aquatica Forsk.) intercropped with Alfred stonecrop (Sedum alfredii Hance) in a Cd-contaminated soil inoculated with Glomus caledonium and/or applied with biochar. Compared with the monocultural control, intercropping with stonecrop (IS) decreased kangkong Cd acquisition via rhizosphere competition, and also decreased kangkong yield. Gc inoculation (+M) accelerated growth and Cd acquisition of stonecrop, and hence resulted in further decreases in kangkong Cd acquisition. Regardless of IS and +M, biochar addition (+B) increased kangkong yield via elevating soil available P, and decreased soil Cd phytoavailability and kangkong Cd concentration via increasing soil pH. Compared with the control, the treatment of IS + M + B had a substantially higher kangkong yield (+25.5%) with a lower Cd concentration (−62.7%). Gc generated additive effects on soil alkalinization and Cd stabilization to biochar, causing lower DTPA-extractable (phytoavailable) Cd concentrations and post-harvest transfer risks. PMID:24728157

    This article presents and technically describes a new field spectro-goniometer system for the ground-based characterization of the surface reflectance anisotropy under natural illumination conditions developed at the Alfred Wegener Institute (AWI). The spectro-goniometer consists of a Manual Transportable Instrument platform for ground-based Spectro-directional observations (ManTIS), and a hyperspectral sensor system. The presented measurement strategy shows that the AWI ManTIS field spectro-goniometer can deliver high quality hemispherical conical reflectance factor (HCRF) measurements with a pointing accuracy of ±6 cm within the constant observation center. The sampling of a ManTIS hemisphere (up to 30° viewing zenith, 360° viewing azimuth) needs approx. 18 min. The developed data processing chain in combination with the software used for the semi-automatic control provides a reliable method to reduce temporal effects during the measurements. The presented visualization and analysis approaches of the HCRF data of an Arctic low growing vegetation showcase prove the high quality of spectro-goniometer measurements. The patented low-cost and lightweight ManTIS instrument platform can be customized for various research needs and is available for purchase.

    The atmospheric water vapor plays a dominant role in the hydrological cycle and in the radiative balance. It is very important for the greenhouse effect in climate modelling as well as for short term numerical weather prediction. Specific humidities derived from CHAMP/GPS are compared with the High resolution Regional weather forecast Model HRM of the Deutscher Wetterdienst over Europe during the BALTEX/Bridge baseline period (October 1999 to February 2002): The model shows slightly larger specific humidities than the radio occultation data obtained from CHAMP (decreasing with increasing height) up to about 1.5~g/kg. Vertically integrated water vapor (IWV) data derived from the CHAMP/GPS profiles are also compared with IWV data derived from AMSU/B data over Antarctica. The AMSU/B IWV data were calculated using an algorithm of Miao (1999). The mean difference between both datasets is with -0.08 kg/m2 quite low and the standard deviation is about 0.79 kg/m2.[0.3cm] Miao, J: Retrieval of Atmospheric Water Vapor Content in Polar Regions Using Spaceborne Microwave Radiometry, Ph.D. thesis, Reports on Polar Research 289, Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany, 1998

    2014-05-01

    At the dawn of the 20th Century Alfred Wegener proposed the existence of a supercontinent - Pangaea - gathering all the continental masses on Earth. Five decades later, while seeding the theory of plate tectonics, Tuzo Wilson introduced a new concept that would become known as Wilson cycles, which describes the evolution of oceans: 1) opening and spreading, 2) foundering of the passive margins and development of new subduction zones and 3) consumption and closure. Later on, in the 70's evidences for the existence of a number of other supercontinents and ancient oceans on Earth's history started to emerge. Today, concepts like supercycles, supercontinents, superoceans and Wilson cycles are loosely used. However, several important questions remain. How do subduction zones initiate in pristine oceans? Which major ocean on Earth will close to form the next supercontinent? The Atlantic (introversion), the Pacific (extroversion), or both? Are Wilson cycles of lower order than Supercycles? Are we in an abnormally long supercycle? Is there any cyclicity at all? These are some of the questions that we will tentatively address together with the proposal of several future scenarios for the evolution of Earth's oceans and continents.

    Objective Wegener's granulomatosis (WG) is a systemic inflammatory disease causing substantial morbidity. This study seeks to understand the biology underlying WG, and to discover markers of disease activity useful in prognosis and treatment guidance. Methods Gene expression profiling was performed using total RNA from PBMC and granulocyte fractions from 41 WG patients and 23 healthy controls. Gene set enrichment analysis (GSEA) was performed to search for candidate WG-associated molecular pathways and disease activity biomarkers. Principal component analysis (PCA) was used to visualize relationships between subgroups of WG patients and controls. Longitudinal changes in PR3 expression were evaluated using RT-PCR, and clinical outcomes including remission status and disease activity were determined using the BVAS-WG. Results We identified 86 genes significantly up-regulated in WG PBMCs and 40 in WG PMNs relative to controls. Genes up-regulated in WG PBMCs were involved in myeloid differentiation, and included the WG autoantigen, PR3. The coordinated regulation of myeloid differentiation genes was confirmed by gene set analysis. Median expression values of the 86 WG PBMC genes were associated with disease activity (p=1.3 × 10−4), and patients expressing these genes at a lower level were only modestly different from healthy controls (p=0.07). PR3 transcription was significantly up-regulated in the PBMCs (p=1.3 ×10−5, FDR=0.002), but not in the PMNs (p=0.03, FDR=0.28) of WG patients, and changes in BVAS-WG tracked with PBMC PR3 RNA levels in a preliminary longitudinal analysis. Conclusion Transcription of PR3 and related myeloid differentiation genes in PBMCs may represent novel markers of disease activity in WG. PMID:20155833

    Between 25 and 27 December 1999 two very intense cyclones, named Lothar and Martin, swept across northern and western France causing substantial life and property loss. In this work, the finite volume general circulation model and data assimilation system (fvDAS) developed at the Data Assimilation Office of the NASA Goddard Space and Flight Center is being used to investigate these storms. In the first part of this article the dynamics of the storms is analyzed, and some important mechanisms are unveiled. The second part describes a set of eleven data assimilation experiments to study the impact of different data types on the automated analyses. Cloud-track winds provided by EUMETSAT and surface winds from QuikSCAT are being used. These data are assimilated with a range of different parameter settings of the forecast error covariance model. The results show that generally the additional wind data set have positive impacts on the analyses: particularly, the analysis of Lothar can be slightly improved by using the Eumetsat winds, and the analysis of Martin can be strongly improved by using the full-resolution QuikSCAT winds with a more localized influence. The third part of this article is focused on the forecast of Lothar which is very well predicted in the 1-5 day range by the fvDAS system.

  4. The excluded philosophy of evo-devo? Revisiting C.H. Waddington's failed attempt to embed Alfred North Whitehead's "organicism" in evolutionary biology.

    2011-01-01

    Though a prominent British developmental biologist in his day, a close friend of Theodosius Dobzhansky, and a frequent correspondent with Ernst Mayr, C.H. Waddington did not enter the ranks of "architect" of the Modern Synthesis. By the end of his career, in fact, he recognized that other biologists reacted to his work "as though they feel obscurely uneasy"; and that the best that some philosophers of biology could say of his work was that he was not "wholly orthodox" (Waddington 1975c, 11). In this essay, I take Waddington's self-assessments at face value and explore three potential reasons why his work did not have more of a direct impact: Waddington's explicit support for the philosophy of Alfred North Whitehead; a lack of institutional support; and Waddington's occasional marginalization from the core network of American neo-Darwinians. Though excluded from the Modern Synthesis in the mid-20th century, it now appears that Waddington's work does undergird the emerging evo-devo synthesis. Whether this indicates concomitant, if implicit, support for Whiteheadian philosophy is an interesting question not explored here.

    Alfred E. Bergeat, originated from a family, who produced gold-glance in a factory (porcelain painting), studied mineralogy and geology at the University of Munich from 1886 to 1892. Due to the results of his habilitation work on the volcanism of island arcs, especially of the Stromboli volcanic island in the Tyrrhenian Sea, he became a recognized volcanologist and specialist in volcanic petrography. He further became an explorer of syngenetic, epigenetic and deuterogenic ore deposits at the mining academies (Bergakademien) of Freiberg (Saxony) and Clausthal (Harz mountains). He described these ore deposits in a two-volume manual (1904-1906) which was summarized again in 1913. After his early death in 1924, the two manuals “Die Vulkane” (1925) and “Vulkankunde” (1927) were posthumously published by his colleague and friend Karl Sapper (1866-1945).

    The importance of instrument firms in the development of psychology, and science in general, should not be underestimated since it would not have been possible for various leading psychologists at the turn of the twentieth century to conduct certain experiments without the assistance of instrument makers, as is often the case today. To illustrate the historical perspective introduced here, the example of Alfred Binet is taken, as he is an interesting case of a psychologist working in close collaboration with various French instrument designers of the time. The objective of this article is twofold: (1) to show the considerable activity carried out by early psychologists to finalize new laboratory instruments in order to develop their research projects; (2) to reassess the work of a major figure in French psychology through his activity as a designer of precision instruments. The development of these new instruments would certainly have been difficult without the presence in Paris of numerous precision instrument manufacturers such as Charles Verdin, Otto Lund, Henri Collin, and Lucien Korsten, on whom Binet successively called in order to develop his projects in the field of experimental psychology. © 2016 Wiley Periodicals, Inc.

  7. Effects of the Wegener-Bergeron-Findeisen process on global black carbon distribution

    We systematically investigate the effects of Wegener-Bergeron-Findeisen process (hereafter WBF) on black carbon (BC) scavenging efficiency, surface BCair, deposition flux, concentration in snow (BCsnow, ng g-1), and washout ratio using a global 3-D chemical transport model (GEOS-Chem). We differentiate riming- versus WBF-dominated in-cloud scavenging based on liquid water content (LWC) and temperature. Specifically, we implement an implied WBF parameterization using either temperature or ice mass fraction (IMF) in mixed-phase clouds based on field measurements. We find that at Jungfraujoch, Switzerland, and Abisko, Sweden, where WBF dominates in-cloud scavenging, including the WBF effect strongly reduces the discrepancies of simulated BC scavenging efficiency and washout ratio against observations (from a factor of 3 to 10 % and from a factor of 4-5 to a factor of 2). However, at Zeppelin, Norway, where riming dominates, simulation of BC scavenging efficiency, BCair, and washout ratio become worse (relative to observations) when WBF is included. There is thus an urgent need for extensive observations to distinguish and characterize riming- versus WBF-dominated aerosol scavenging in mixed-phase clouds and the associated BC scavenging efficiency. Our model results show that including the WBF effect lowers global BC scavenging efficiency, with a higher reduction at higher latitudes (8 % in the tropics and up to 76 % in the Arctic). The resulting annual mean BCair increases by up to 156 % at high altitudes and at northern high latitudes because of lower temperature and higher IMF. Overall, WBF halves the model-observation discrepancy (from -65 to -30 %) of BCair across North America, Europe, China and the Arctic. Globally WBF increases BC burden from 0.22 to 0.29-0.35 mg m-2 yr-1, which partially explains the gap between observed and previous model-simulated BC burdens over land. In addition, WBF significantly increases BC lifetime from 5.7 to ˜ 8 days. Additionally

    This paper examines Karl Alfred von Zittel’s practice in order to uncover the roots of so-called idiographic paleontology.The great American paleontologist Stephen Jay Gould (1941–2002) defined the discipline of idiographic paleontology as illustration and description of the morphological features of extinct species. However, this approach does not investigate macroevolutionary patterns and processes. On the contrary, the paleobiological revolution of the 1970s implemented an epistemic methodology that illustrates macrovelutionary patterns and laws by combining idiographic data with a nomothetic form of explanation. This article elucidates the features of the idiographic data as well as the acquired knowledge coupled with this approach. First of all, Heinrich G. Bronn’s (1800–1862) statistical method is analyzed. Zittel’s practice arose as a reaction against the approximate conclusions reached by Bronn’s quantitative approach. Second, the details of Zittel’s methodology are described in order to bring out its peculiarities.The microscope played a pivotal role in creating and forming Zittel’s morphological data. This analysis sheds new light on the reasons behind the so-called ideographic paleontology, thus revising Gould’s historical reconstruction, as well as on the notion of paleontological data. However, even though Zittel aimed at reaching precise and stable conclusions,his data cannot be used for elucidating evolutionary mechanisms: they are scientific in a purely descriptive sense, but completely useless for biological investigations. Finally, this paper examines how Zittel’s methodology affects the contemporary paleobiological enterprise and thereby reflects upon the notion of natural history.

    The Global Precipitation Measurement (GPM) Integrated Multi-satellite Retrievals for GPM (IMERG) products provide quasi-global (60° N-60° S) precipitation estimates, beginning March 2014, from the combined use of passive microwave (PMW) and infrared (IR) satellites comprising the GPM constellation. The IMERG products are available in the form of near-real-time data, i.e., IMERG Early and Late, and in the form of post-real-time research data, i.e., IMERG Final, after monthly rain gauge analysis is received and taken into account. In this study, IMERG version 3 Early, Late, and Final (IMERG-E,IMERG-L, and IMERG-F) half-hourly rainfall estimates are compared with gauge-based gridded rainfall data from the WegenerNet Feldbach region (WEGN) high-density climate station network in southeastern Austria. The comparison is conducted over two IMERG 0.1° × 0.1° grid cells, entirely covered by 40 and 39 WEGN stations each, using data from the extended summer season (April-October) for the first two years of the GPM mission. The entire data are divided into two rainfall intensity ranges (low and high) and two seasons (warm and hot), and we evaluate the performance of IMERG, using both statistical and graphical methods. Results show that IMERG-F rainfall estimates are in the best overall agreement with the WEGN data, followed by IMERG-L and IMERG-E estimates, particularly for the hot season. We also illustrate, through rainfall event cases, how insufficient PMW sources and errors in motion vectors can lead to wide discrepancies in the IMERG estimates. Finally, by applying the method of Villarini and Krajewski (2007), we find that IMERG-F half-hourly rainfall estimates can be regarded as a 25 min gauge accumulation, with an offset of +40 min relative to its nominal time.

    Two types of Arctic mixed-phase clouds observed during the ISDAC and M-PACE field campaigns are simulated using a 3-dimensional cloud-resolving model (CRM) with size-resolved cloud microphysics. The modeled cloud properties agree reasonably well with aircraft measurements and surface-based retrievals. Cloud properties such as the probability density function (PDF) of vertical velocity (w), cloud liquid and ice, regimes of cloud particle growth, including the Wegener-Bergeron-Findeisen (WBF) process, and the relationships among properties/processes in mixed-phase clouds are examined to gain insights for improving their representation in General Circulation Models (GCMs). The PDF of the simulated w is well represented by a Gaussian function, validating, at least for arctic clouds, the subgrid treatment used in GCMs. The PDFs of liquid and ice water contents can be approximated by Gamma functions, and a Gaussian function can describe the total water distribution, but a fixed variance assumption should be avoided in both cases. The CRM results support the assumption frequently used in GCMs that mixed phase clouds maintain water vapor near liquid saturation. Thus, ice continues to grow throughout the stratiform cloud but the WBF process occurs in about 50% of cloud volume where liquid and ice co-exist, predominantly in downdrafts. In updrafts, liquid and ice particles grow simultaneously. The relationship between the ice depositional growth rate and cloud ice strongly depends on the capacitance of ice particles. The simplified size-independent capacitance of ice particles used in GCMs could lead to large deviations in ice depositional growth.

    The internal layering architecture of ice sheets, detected with radio-echo sounding (RES), contains clues to past ice-flow dynamics and mass balance. A common way of relating the recorded travel time of RES reflections to depth is by integrating a wave-speed distribution. This results in an increasing absolute error with depth. We present a synchronization of RES-internal layers of different radar systems (Alfred Wegener Institute, Center for Remote Sensing of Ice Sheets, Istituto Nazionale di Geofisica e Vulcanologia, British Antarctic Survey and University of Texas Institute for Geophysics) with ice-core records from the Antarctic deep drill site Dome C. Synthetic radar traces are obtained from measurements of ice-core density and conductivity with a 1D model of Maxwell's equations. The reflection peaks of the different radar systems' measurements are shifted by a wiggle-matching algorithm, so they match the synthetic trace. In this way, we matched pronounced internal reflections in the RES data to conductivity peaks with considerably smaller depth uncertainties, and assigned them with the ice-core age. We examine the differences in shifts and resolution of the different RES data to address the question of their comparability and combined analysis for an extensive age-depth distribution.

    We are presenting new magnetic and gravity data of a high-resolution aerogephysical survey over the area of the Sør Rondane Mountains in the eastern Dronning Maud Land (DML). The aircraft survey is part of the joint geological and geophysical GEA campaign (Geodynamic Evolution of East Antarctica) of the Federal Agency for Geosciences and Natural Resources (BGR) and Alfred-Wegener-Institute for Polar and Marine Research (AWI), in cooperation with the Universities of Ghent, Bremen and Bergen. It was completed during the Antarctic summer season 2012/13, covering an area of more than 100000 square kilometer with a line spacing of 5 km. The data will be correlated with geological structures exposed in the mountain range as well as matched and merged with the data sets of the eastern and southern DML (acquired by AWI during the last decade) for comparison and discussion in the greater context of the tectonic evolution of East Antarctica. Preliminary results show that the magnetic anomaly pattern over the Sør Rondane Mountains differs from the pattern found over the central DML mountains as well as from the low amplitude pattern in between both regions, indicating a significant difference in the evolution of this region, which is in accordance with latest geological findings in this region.

    The recent thinning and shrinking of the Arctic sea ice cover has increased the interest in seasonal sea ice forecasts. Typical tools for such forecasts are numerical models of the coupled ocean sea ice system such as the North Atlantic/Arctic Ocean Sea Ice Model (NAOSIM). The model uses as input the initial state of the system and the atmospheric boundary condition over the forecasting period. This study investigates the potential of remotely sensed ice thickness observations in constraining the initial model state. For this purpose it employs a variational assimilation system around NAOSIM and the Alfred Wegener Institute's CryoSat-2 ice thickness product in conjunction with the University of Bremen's snow depth product and the OSI SAF ice concentration and sea surface temperature products. We investigate the skill of predictions of the summer ice conditions starting in March for three different years. Straightforward assimilation of the above combination of data streams results in slight improvements over some regions (especially in the Beaufort Sea) but degrades the over-all fit to independent observations. A considerable enhancement of forecast skill is demonstrated for a bias correction scheme for the CryoSat-2 ice thickness product that uses a spatially varying scaling factor.

  16. Engaging with Lyell: Alfred Russel Wallace's Sarawak Law and Ternate papers as reactions to Charles Lyell's Principles of Geology.

    2013-12-01

    Alfred Russel Wallace (1823-1913) and Charles Darwin (1809-1882) are honored as the founders of modern evolutionary biology. Accordingly, much attention has focused on their relationship, from their independent development of the principle of natural selection to the receipt by Darwin of Wallace's essay from Ternate in the spring of 1858, and the subsequent reading of the Wallace and Darwin papers at the Linnean Society on 1 July 1858. In the events of 1858 Wallace and Darwin are typically seen as central players, with Darwin's friends Charles Lyell (1797-1875) and Joseph Dalton Hooker (1817-1911) playing supporting roles. This narrative has resulted in an under-appreciation of a more central role for Charles Lyell as both Wallace's inspiration and foil. The extensive anti-transmutation arguments in Lyell's landmark Principles of Geology were taken as the definitive statement on the subject. Wallace, in his quest to solve the mystery of species origins, engaged with Lyell's arguments in his private field notebooks in a way that is concordant with his engagement with Lyell in the 1855 and 1858 papers. I show that Lyell was the object of Wallace's Sarawak Law and Ternate papers through a consideration of the circumstances that led Wallace to send his Ternate paper to Darwin, together with an analysis of the material that Wallace drew upon from the Principles. In this view Darwin was, ironically, intended for a supporting role in mediating Wallace's attempted dialog with Lyell.

    In the 1880s, Alfred Russel Wallace, the celebrated co-discoverer of natural selection, launched himself into the centre of a politicised and polarised debate over the unpopular compulsory vaccination laws in England. Wallace never wavered in his belief that smallpox vaccination was useless and likely dangerous. Six years before his death, the anti-vaccinationists successfully secured a conscience clause that effectively dismantled the compulsory vaccination laws. Several other important Victorian scientists joined Wallace in the fight to repeal compulsory vaccination arguing that widely held views on the effectiveness of vaccination and evidence for immunity were inconclusive in the light of (then) contemporary standards of evidence. This article situates Wallace's anti-vaccination logic within the broader matrix of sociopolitical and cultural reform movements of the late Victorian era. Additionally it provides the first detailed analysis of his critique of vaccination science, in particular the role statistics played in his arguments. In this period, both pro-vaccinationists and anti-vaccinationists invested great efforts in collating and analysing statistical data sets that either supported or refuted the claims of vaccination's effectiveness. While each side presented 'controlled' case studies to support their assertions, without an unambiguous test to measure or demonstrate vaccination's effectiveness, the anti-vaccinationists continued to mount credible statistical critiques of vaccination science.

    Understanding and identifying the spatial-temporal changes in the natural environment is crucial for monitoring and evaluating conservation efforts, as well as understanding the impact of human activities on natural resources, informing responsible land management, and promoting better decision-making. Conservation areas are often under pressure from expanding farming and related industry, invasive alien vegetation, and an ever-increasing human settlement footprint. This study focuses on detecting changes to the Prince Alfred Hamlet commonage, near Ceres in the Cape Floral Kingdom. It was chosen for its high conservation value and significance as a critical water source area. The study area includes a fast-growing human settlement footprint in a highly productive farming landscape. There are conflicting development needs as well as risks to agricultural production, and both of these threaten the integrity of the ecosystems which supply underlying services to both demands on the land. Using a multi-disciplinary approach and high-resolution satellite imagery, land use and land cover changes can be detected and classified, and the results used to support the conservation of biodiversity and wildlife, and protect our natural resources. The aim of this research is to study the efficacy of using remote sensing and GIS techniques to detect changes to critical conservation areas where disturbances can be understood, and therefore better managed and mitigated before these areas are degraded beyond repair.

    During the RACEPAC field campaign in April and May 2014, research flights were made with the Polar 5 and Polar 6 aircraft from the Alfred Wegener Institute in Arctic clouds near Inuvik, Northwest Territories, Canada. One flight with the Polar 6 aircraft, done on May 16, 2014, flew under precipitating, stratiform, mid-level clouds with several penetrations through cloud base. Measurements with HALOHolo, an airborne digital in-line holographic instrument for cloud particles, show ice particles in a field of other cloud particles in a local three-dimensional sample volume (~14x19x130 mm3 or ~35 cm^3). Each holographic sample volume is a snapshot of a 3-dimensional piece of cloud at the cm-scale with typically thousands of cloud droplets per sample volume, so each sample volume yields a statistically significant droplet size distribution. Holograms are recorded at a rate of six times per second, which provides one volume sample approx. every 12 meters along the flight path. The size resolution limit for cloud droplets is better than 1 µm due to advanced sizing algorithms. Shown are preliminary results of, (1) the ice/liquid water partitioning at the cloud base and the distribution of water droplets around each ice particle, and (2) spatial and temporal variability of the cloud droplet size distributions at cloud base.

    EXTASE is a spin-off project from the MUPUS (Rosetta Lander) thermal probe, both funded by DLR. The thermal probe will be tested in various environments and fields, e.g. in snow research, agriculture, permafrost, monitoring waste deposits and the heat released by decomposition, ground truth for remote sensing etc. The probe is a glass-fibre tube of 1cm diameter, about 32 cm long and carries of 16 sensors for measuring temperature profiles. Each of the sensors can also be heated for in situ measurements of the thermal diffusivity of the penetrated layers, from which we can derive the thermal conductivity. All necessary connections and the sensors itself are printed on a foil which is rolled and glued to the inner wall of the tube. This design results in the significant advantage that the measurements can be done in-situ. No excavation of material is required to measure the thermal conductivity, for instance. Presently we are concentrating on soil science and snow research.We made several measurements in different conditions with prototypes of the probe so far. Among other things, we measured soil temperatures together with meteorological boundary conditions in cooperation with the local Institute of Agrophysics in Lublin (Poland). The first measurements in snow under natural conditions were made on Svalbard (Spitzbergen) together with the Alfred-Wegener-Institute in Bremerhaven (Germany). First results of the measuring campaigns are shown.

Emphasis is placed on the methods of operation required to find, remove, identify, and determine cause of death in these individuals. Simultaneously, evidence must be identified and preserved in a homicide investigation of this type. Close cooperation must exist among multiple varied agencies and disciplines to accomplish the task and to prepare for subsequent analysis and courtroom testimony required by the criminal justice system. Terrorism, both foreign and domestic, is a current fact and will be a problem in many forms in the 21st century. No one is immune. The key to success is to plan ahead and be aware of available resources. Preplanning for short comings and difficult issues, and most importantly, relying on team work will allow future participants to successfully meet and complete the challenge. The investigation developed detailed injury data and mechanisms that were available for subsequent judicial proceedings and for in-depth epidemiological studies spearheaded by the Injury Prevention Service of the Oklahoma State Department of Health.

Clinical features of the full blown generalized systemic vasculitis are usually found in the respiratory tract and the kidney. Pulmonary involvement of Wegener's granulomatosis shows commonly nodules and cavitations but also diffuse alveolar hemorrhage. We report the case of a 57 year-old man suffering from dyspnea, thoracal pain, arthralgia, purpura, scleritis and tinitus. Specimen of the kidney showed segmental glomerulosclerosis and tubulointerstitial nephritis. Because of the presence of cANCA Wegener's disease was assumed. Pulmonary infiltrates developed under immunosuppressive treatment with cyclophosphamid. As differential diagnosis of the pulmonary infiltrates, we considered invasive pulmonary aspergillosis as well as infiltrates due to Wegener's granulomatosis. In spite of maximal therapeutic management of patient died of respiratory and cardiovascular failure. The findings at autopsy showed distinct invasive pulmonary aspergillosis and perifocal hemorrhage.

    Postgraduate education is gaining increasing importance and has been identified as one instrument to foster quality and promote networking, both in research and in education. Exchange and co-operation between graduate programmes that have related topics produce added value for all. Students have access to a range of research facilities, course offers, and a broad scientific community from which they can start building their individual scientific network. Larger events like PhD conferences, career symposia or cost-intensive trainings are more easily tackled by joining forces of various players. The postgraduate programmes ESSReS-PEP-POLMAR are part of a larger network of marine and climate science programmes in the north-western region of Germany and together host up 180 (23 ESSReS, 130 POLMAR, 30 PEP) PhD/Master students in their respective programmes. Here, we will present a number of joint activities from this collaboration. Today, the PhD education is completely different to that from 15 years ago due to a variety of different scientific offerings including e.g. excursions, soft skill courses and special seminars. In the framework of the ESSReS-PEP-POLMAR concept the Postgraduate Programme Environmental Physics (PEP) at the University of Bremen educates the participants on the complex relationship between atmosphere, hydrosphere (ocean), cryosphere (ice region) and solid earth (land). Here, the learning of experimental methods in environmental physics at the most advanced level, numerical data analysis using supercomputers, and data interpretation via sophisticated methods prepare students for a scientific career. Within cooperation with the Ocean University of China (OUC) students are participating one year in the PEP programme during their master studies since 2006, to get finally a double degree of both universities. Two different ways to further graduation are currently possible at the Alfred Wegener Institute. The Helmholtz Graduate School for Polar and

Vogel do exist, which facts do they prove about his career and which interpretations of his point of view of phytotherapy do they allow. With the methods in medical history (heuristic, critic, interpretation) video, audio and written documents from the A. Vogel Museum and A. Vogel publisher in Teufen, the A. Vogel collection in the Museum in Aesch and the Bioforce AG in Roggwil have been examined. From 1923 to 1932 A. Vogel runs a grocer's shop or a herb and health-food store in Basel and later Bern, Zürich and Solothurn. The economic success of his health-food stores and his interest in the field of naturopathy enable him to take part in a training to become a 'natural doctor' and in 1933 he is registered by the 'Natural Doctors Association of Switzerland'. From 1935 on he is working as a nutritionalist in his own spa pension in Trogen and produces plant extracts in his 'Laboratory Bioforce'. From 1937 to 1957 he has a spa hotel in Teufen and is producer of extracts from fresh plants. He is able to travel all continents of the world from 1958 on, in order to observe customs and medical habits of different tribes. He writes about his findings in his own magazine and books.

    During the Arctic Study of Tropospheric Aerosol, Clouds and Radiation (ASTAR) in March and April 2007, measurements obtained at the AWIPEV Research station in Ny-Ålesund, Spitsbergen (operated by the Alfred-Wegener-Institute for Polar and Marine Research and the Institut polaire français Paul-Emile Victor), supported the airborne campaign. This included Lidar data from the Koldewey Aerosol Raman Lidar (KARL) and the Micro Pulse Lidar (MPL), located in the atmospheric observatory as well as photometer data and the daily launched radiosonde. The MPL features nearly continuous measurements; the KARL was switched on whenever weather conditions allowed observations (145 h in 61 days). From 1 March to 30 April, 71 meteorological balloon soundings were performed and compared with the corresponding MPL measurements; photometer measurements are available from 18 March. For the KARL data, a statistical overview based on the optical properties backscatter ratio and volume depolarization can be given. The altitudes of the occurrence of the named features (subvisible and visible ice and water as well as mixed-phase clouds, aerosol layers) as well as their dependence on different air mass origins are analyzed. Although the spring 2007 was characterized by rather clean conditions, diverse case studies of cloud and aerosol occurrence during March and April 2007 are presented in more detail, including temporal development and main optical properties as backscatter, depolarization and extinction coefficients. Links between air mass origins and optical properties can be presumed but need further evidence.

    2010-12-01

    We brought a party of 15 scientists, graduate students, and educators to King George Island, the largest of the South Shetland Islands, just off the Antarctic Peninsula, for an international workshop on Antarctica and global climate change in January 2010. Participants included professors, young scientists and graduate students from the Obukhov Institute of Atmospheric Physics, the University of Maryland, the University of Wisconsin, and the Michigan Technological University. Lindsay Bartholomew, an education and outreach specialist at the Museum of Science and Industry in Chicago connected the workshop via video and Internet with an audience of museum visitors. Scientists living and working at Bellingshausen, including Hans-Ulrich Peter, an eminent ecologist from Jena University (Germany), and Bulat Movlyudov (Institute of Geography, Moscow), a distinguished glaciologist, participated in the workshop. Field trips led by Peter and Movlyudov and others were made by day and lectures were held by night. Professors and graduate students made cutting-edge presentations on such subjects as permafrost, glaciology, and global climate models. Three workshop teams conducted field research projects at the foot of the Bellingshausen Dome icecap - two on carbon cycling and one on permafrost. Major funding sources for the workshop included the Russian Foundation for Basic Research (Russia), Wilderness Research Foundation (USA), NSF, University of Wisconsin at Stevens Point, Alfred Wegener Institute (Germany) and Museum for Science and Industry (Chicago). INACH, the Chilean Antarctic Institute, and IAU, the Uruguayan Antarctic Institute, provided air charter services. On King George Island, our group was billeted at Russia’s Bellingshausen science station.

  19. A study of the stable boundary layer in strong gap flows in northwest Greenland using a research aircraft

    Heinemann, Günther; Drüe, Clemens

    2016-04-01

    Gap flows and the stable boundary layer (SBL) were studied in northwest Greenland during the aircraft-based experiment IKAPOS (Investigation of Katabatic winds and Polynyas during Summer) in June 2010. The measurements were performed using the research aircraft POLAR 5 of Alfred Wegener Institute (AWI, Bremerhaven). Besides navigational and basic meteorological instrumentation, the aircraft was equipped with radiation and surface temperature sensors, two laser altimeters, and video and digital cameras. In order to determine turbulent heat and momentum fluxes, POLAR 5 was instrumented with a turbulence measurement system collecting data on a nose boom with a sampling rate of 100 Hz. In the area of the Nares Strait a stable, but fully turbulent boundary layer with strong winds of 15 m s-1 to 20 m s-1 was found during conditions of relatively warm synoptically induced northerly winds through the Nares Strait. Strong surface inversions were present in the lowest 100 m to 200 m. As a consequence of channeling effects a well-pronounced low-level jet (LLJ) system was documented. The channeling process is consistent with gap flow theory and can be shown to occur at the topographic gap between Greenland and Canada represented by the Smith Sound. While the flow through the gap and over the surrounding mountains leads to the lowering of isotropic surfaces and the acceleration of the flow, the strong turbulence associated with the LLJ leads to the development of an internal thermal SBL past the gap. Turbulence statistics in this fully turbulent SBL can be shown to follow the local scaling behaviour.

    During the Arctic Study of Tropospheric Aerosol, Clouds and Radiation (ASTAR) in March and April 2007, measurements obtained at the AWIPEV Arctic Research Base in Ny-Ålesund, Spitsbergen at 78.9° N, 11.9° E (operated by the Alfred Wegener Institute for Polar and Marine Research - AWI and the Institut polaire français Paul-Emile Victor - IPEV), supported the airborne campaign. This included lidar data from the Koldewey Aerosol Raman Lidar (KARL) and the Micro Pulse Lidar (MPL), located in the atmospheric observatory as well as photometer data and the daily launched radiosonde. The MPL features nearly continuous measurements; the KARL was switched on whenever weather conditions allowed observations (145 h in 61 days). From 1 March to 30 April, 71 meteorological balloon soundings were performed and compared with the concurrent MPL measurements; photometer measurements are available from 18 March. For the KARL data, a statistical overview of particle detection based on their optical properties backscatter ratio and volume depolarization can be given. The altitudes of the occurrence of the named features (subvisible and visible ice and water as well as mixed-phase clouds, aerosol layers) as well as their dependence on different air mass origins are analyzed.

  1. ATLAS - A new Lagrangian transport and mixing model with detailed stratospheric chemistry

    NASA Astrophysics Data System (ADS)

    Wohltmann, I.; Rex, M.; Lehmann, R.

    2009-04-01

    We present a new global Chemical Transport Model (CTM) with full stratospheric chemistry and Lagrangian transport and mixing called ATLAS. Lagrangian models have some crucial advantages over Eulerian grid-box based models, like no numerical diffusion, no limitation of the time step of the model by the CFL criterion, conservation of mixing ratios by design and easy parallelization of code. The transport module is based on a trajectory code developed at the Alfred Wegener Institute. The horizontal and vertical resolution, the vertical coordinate system (pressure, potential temperature, hybrid coordinate) and the time step of the model are flexible, so that the model can be used both for process studies and long-time runs over several decades. Mixing of the Lagrangian air parcels is parameterized based on the local shear and strain of the flow with a method similar to that used in the CLaMS model, but with some modifications like a triangulation that introduces no vertical layers. The stratospheric chemistry module was developed at the Institute and includes 49 species and 170 reactions and a detailed treatment of heterogenous chemistry on polar stratospheric clouds. We present an overview over the model architecture, the transport and mixing concept and some validation results. Comparison of model results with tracer data from flights of the ER2 aircraft in the stratospheric polar vortex in 1999/2000 which are able to resolve fine tracer filaments show that excellent agreement with observed tracer structures can be achieved with a suitable mixing parameterization.

    This study aimed to compare the epidemiology, clinical presentations, management, and outcomes of renal colic presentations in two major academic centers from geographically diverse populations: Qatar (a country in the Afro-Asian stone belt) and South-Eastern Australia (not within a stone belt). We undertook a retrospective cohort study of patients with renal colic who presented to the Hamad General Hospital Emergency Department (HGH-ED), Qatar, and The Alfred ED, Melbourne, Australia, during a period of 1 year from August 1, 2012, to July 31, 2013. Cases were identified using ICD-9-CM codes, and an electronic template was used to record the data on predefined clinical variables. A total of 12,223 from the HGH-ED and 384 from The Alfred ED were identified as renal colic presentations during the study period. The rate of renal colic presentations at the HGH-ED was 27.9 per 1000 ED visits compared to 6.7 per 1000 ED visits at The Alfred ED. Patients presenting to the HGH-ED were significantly younger [34.9 years (29.0-43.4) than The Alfred ED [48 years (37-60); P < 0.001]. The median stone size was larger in the HGH-ED group [6 (4-8) mm] versus The Alfred ED group [4 (3-6) mm, P < 0.001]. The intervention rate in the stone-positive population was significantly higher in the HGH-ED group as opposed to The Alfred ED group (38.7 versus 11.9%, P < 0.001). At the time of discharge, The Alfred ED group received fewer analgesic prescriptions (55.8 versus 83.5%, P < 0.001) and more tamsulosin prescriptions (25.3 versus 11.7%, P < 0.001). Renal colic presentations to the HGH-ED, Qatar, were younger, with larger stone size mostly located in the lower ureter, compared to The Alfred ED, Melbourne, Australia. The findings suggest that the benefits of treatment including medical expulsion therapy will vary between the two populations. Differences in epidemiology and patient mix should be considered while tailoring strategies for effective management of patients

    The Indian Ocean Tsunami on December 26, 2004 caused one of the largest tsunamis in recent times and led to widespread devastation and loss of life. One of the worst hit regions was Banda Aceh, which is the capital of the Aceh province, located in the northern part of Sumatra, 150km from the source of the earthquake. A German-Indonesian Tsunami Early Warning System (GITEWS) (www.gitews.de) is currently under active development. The work presented here is carried out within the GITEWS framework. One of the aims of this project is the development of accurate models with which to simulate the propagation, flooding and drying, and run-up of a tsunami. In this context, TsunAWI has been developed by the Alfred Wegener Institute; it is an explicit, () finite element model. However, the accurate numerical simulation of flooding and drying requires the conservation of mass and momentum. This is not possible in the current version of TsunAWi. The P1NC - P1element guarantees mass conservation in a global sense, yet as we show here it is important to guarantee mass conservation at the local level, that is within each individual cell. Here an unstructured grid, finite volume ocean model is presented. It is derived from the P1NC - P1 element, and is shown to be mass and momentum conserving. Then a number of simulations are presented, including dam break problems flooding over both a wet and a dry bed. Excellent agreement is found. Then we present simulations for Banda Aceh, and compare the results to on-site survey data, as well as to results from the original TsunAWI code.

    The CryoSat-2 satellite is now in the 6th year of data acquisition. With its synthetic aperture radar altimeter, CryoSat-2 achieves great improvements in the along track resolution compared to previous radar altimeter missions like ERS or Envisat. The latitudinal coverage contains major parts of the Arctic marine ice fields where previous missions left a big data gap around the North Pole and especially over the multiyear ice zone north of Greenland. With this unique data set, changes in sea-ice thickness can be investigated in the context of the rapid reduction of the Arctic sea-ice cover which has been observed during the last decades. We present the current state of the CryoSat-2 Arctic sea-ice thickness retrieval that is processed at the Alfred Wegener Institute and available via seaiceportal.de (originally: meereisportal.de). Though biases in sea-ice thickness may occur due to the interpretation of waveforms, airborne and ground-based validation measurements give confidence that the retrieval algorithm enables us to capture the actual distributions of sea-ice regimes. Nevertheless, long time series of data retrievals are essential to estimate trends in sea-ice thickness and volume. Today, more than 20 years of radar altimeter data are potentially available and capable to derive sea ice thickness. However, data originate from satellites with different sensor characteristics. Therefore, it is crucial to study the consistency between single sensors to derive long and consistent time series. We present results from the tested consistency between Antarctic freeboard measurements of the radar altimeters on-board of Envisat and CryoSat-2 for their overlap period in 2011.

    To uniquely classify children with microscopic polyangiitis (MPA), to describe their demographic characteristics, presenting clinical features, and initial treatments in comparison to patients with granulomatosis with polyangiitis (Wegener's) (GPA). The European Medicines Agency (EMA) classification algorithm was applied by computation to categorical data from patients recruited to the ARChiVe (A Registry for Childhood Vasculitis: e-entry) cohort, with the data censored to November 2015. The EMA algorithm was used to uniquely distinguish children with MPA from children with GPA, whose diagnoses had been classified according to both adult- and pediatric-specific criteria. Descriptive statistics were used for comparisons. In total, 231 of 440 patients (64% female) fulfilled the classification criteria for either MPA (n = 48) or GPA (n = 183). The median time to diagnosis was 1.6 months in the MPA group and 2.1 months in the GPA group (ranging to 39 and 73 months, respectively). Patients with MPA were significantly younger than those with GPA (median age 11 years versus 14 years). Constitutional features were equally common between the groups. In patients with MPA compared to those with GPA, pulmonary manifestations were less frequent (44% versus 74%) and less severe (primarily, hemorrhage, requirement for supplemental oxygen, and pulmonary failure). Renal pathologic features were frequently found in both groups (75% of patients with MPA versus 83% of patients with GPA) but tended toward greater severity in those with MPA (primarily, nephrotic-range proteinuria, requirement for dialysis, and end-stage renal disease). Airway/eye involvement was absent among patients with MPA, because these GPA-defining features preclude a diagnosis of MPA within the EMA algorithm. Similar proportions of patients with MPA and those with GPA received combination therapy with corticosteroids plus cyclophosphamide (69% and 78%, respectively) or both drugs in combination with

    WegenerNet Feldbach region (WEGN), a pioneering experiment for weather and climate observations, has recently completed its first 10-year precipitation measurement cycle. The WEGN has measured precipitation, temperature, humidity, and other parameters since the beginning of 2007, supporting local-level monitoring and modeling studies, over an area of about 20 km x 15 km centered near the City of Feldbach (46.93 ˚ N, 15.90 ˚ E) in the Alpine forelands of southeast Austria. All the 151 stations in the network are now equipped with high-quality Meteoservis sensors as of August 2016, following an equipment with Friedrichs sensors at most stations before, and continue to provide high-resolution (2 km2/5-min) gauge based precipitation measurements for interested users in hydro-meteorological communities. Here we will present overall characteristics of the WEGN, with a focus on sub-daily precipitation measurements, from the data processing (data quality control, gridded data products generation, etc.) to data applications (e.g., ground validation of satellite estimates). The latter includes our recent study on the propagation of uncertainty from rainfall to runoff. The study assesses responses of small-catchment runoff to spatial rainfall variability in the WEGN region over the Raab valley, using a physics-based distributed hydrological model; Water Flow and Balance Simulation Model (WaSiM), developed at ETH Zurich (Schulla, ETH Zurich, 1997). Given that uncertainty due to resolution of rainfall measurements is believed to be a significant source of error in hydrologic modeling especially for convective rainfall that dominates in the region during summer, the high-resolution of WEGN data furnishes a great opportunity to analyze effects of rainfall events on the runoff at different spatial resolutions. Furthermore, the assessment can be conducted not only for the lower Raab catchment (area of about 500 km2) but also for its sub-catchments (areas of about 30-70 km2

    The RTopo-1 data set of Antarctic ice sheet/shelf geometry and global ocean bathymetry has proven useful not only for modelling studies of ice-ocean interaction in the southern hemisphere. Following the spirit of this data set, we introduce a new product (RTopo-2) that contains consistent maps of global ocean bathymetry, upper and lower ice surface topographies for Greenland and Antarctica, and global surface height on a spherical grid with now 30 arc seconds resolution. We used the General Bathymetric Chart of the Oceans (GEBCO_2014) as the backbone and added the International Bathymetric Chart of the Arctic Ocean version 3 (IBCAOv3) and the International Bathymetric Chart of the Southern Ocean (IBCSO) version 1. To achieve a good representation of the fjord and shelf bathymetry around the Greenland continent, we corrected data from earlier gridded products in the areas of Petermann Glacier, Hagen Bræ and Helheim Glacier assuming that sub-ice and fjord bathymetries roughly follow plausible Last Glacial Maximum ice flow patterns. For the continental shelf off northeast Greenland and the floating ice tongue of Nioghalvfjerdsfjorden Glacier at about 79°N, we incorporated a high-resolution digital bathymetry model including all available multibeam survey data for the region. Radar data for ice surface and ice base topographies of the floating ice tongues of Nioghalvfjerdsfjorden Glacier and Zachariæ Isstrøm have been obtained from the data centers of Technical University of Denmark (DTU), Operation Icebridge (NASA/NSF) and Alfred Wegener Institute (AWI). For the Antarctic ice sheet/ice shelves, RTopo-2 largely relies on the Bedmap-2 product but applies corrections for the geometry of Getz, Abbot and Fimbul ice shelf cavities. The data set is available in full and in regional subsets in NetCDF format from the PANGAEA database.

  18. Surface energy balance and turbulence measurements on Warszawa Icefield, King George Island, West Antarctica

    The Antarctic Peninsula is amongst the fastest warming places on Earth and further temperature increase is to be expected. It has undergone rapid environmental changes in the past decades. Exceptional rates of surface air temperature increases (2.5K in 50 years) are concurrent with retreating glacier fronts, an increase in melt areas, surface lowering and rapid retreat of glaciers, break-up and disintegration of ice shelves. The South Shetland Islands are located on the northern tip of the Antarctic Peninsula and are especially vulnerable to climate change due to their maritime climate. For King George Island we have compiled a unique data set comprising direct measurements of evaporation and sensible heat flux by eddy covariance on the Warszawa Icefield over 1.5 years from November 2010 to 2012 in combination with a fully equipped automated weather station measuring long- and short-wave radiation components, profiles of temperature, humidity and wind velocities as well as glacier ice temperatures. The combination with the eddy covariance data allows for analysis of variability and seasonality of surface energy balance components on a glacier for one and a half years. Repeat measurements of snow accumulation and surface lowering along transects on the glacier and at different locations on King George Island are used for analysis of multi-sensor satellite data to identify melt patterns and bare ice areas during summer within the source area of the ground measurements. In combination with long-term time series of weather data, these data give indication of the sensitivity of the ice cap to the ongoing changes. This research is part of the ESF project IMCOAST funded by BMBF. Field work was carried out at the Dallmann laboratory (Carlini station, King George Island/Isla 25 de Mayo) in cooperation of the Instituto Antartico Argentino (Argentina) and the Alfred-Wegener Institute of Marine and Polar Research (Germany).

  1. First results from a new interdisciplinary robotic vehicle for under-ice research

    Research at the ice-water interface below drifting sea-ice is crucial for the investigation of the fluxes of energy, momentum and matter across the atmosphere-ice-ocean boundary. Transmission of solar energy through the ice and snow layers causes warming of the upper ocean and melting of the ice itself. It is also a key factor for in and under-ice primary production, supplying the ice associated food-chain and causing carbon export to deeper water layers and the sea floor. The complex geometry of sea ice does not only cause a large spatial variability in optical properties of the ice cover, but also influences biomass accumulations and especially the hydrodynamic interaction between the ice cover and the uppermost layers of the ocean. Access to the ice underside is however still sparse, as diving operations are risky and logistically challenging. In the last decade, robotic underwater technologies have evolved significantly and enabled the first targeted large-scale observations by remotely operated and autonomous underwater vehicles. A new remotely operated vehicle was commissioned for under ice research at the Alfred Wegener Institute supported by the FRAM infrastructure program of the Helmholtz-Society. Apart from proven under-ice navigation and operation capabilities, the vehicle provides an extended interdisciplinary sensor platform supporting oceanographic, biological, biogeochemical and physical sea-ice research. Here we present the first preliminary data obtained with the new vehicle during the PS101 expedition of the German icebreaker RV Polarstern to the Central Arctic in September and October 2016. Apart from measurements of spectral light transmittance of sea ice during the autumn freeze-up, we show vertical profiles of the bio-optical and oceanographic properties of the upper water column. This data is combined with under-ice topography obtained from upward-looking multibeam sonar, still imagery and HD-video material.

  2. The Dark Side of the Earth

    Frankel, Henry

    1986-10-01

    Wood's The Dark Side of the Earth is another addition to the growing list of books on the recent revolution in the earth sciences. Wood rightly points out that any new book on the topic should break new ground. In the preface, he writes of himself and his book that he has benefited from previous accounts by saving himself research time, and that his book, unlike others, “attempts to tell one complete story of the study of the Earth, geologists, geophysicists, dreamers and all” (p. vi). Wood is ambitious, for his work covers much of 19th-century geology as well as the development, reception, rejection, and eventual acceptance of mobilist ideas. Before discussing the work of the German meteorologist and geophysicist Alfred L. Wegener, American glacial geomorphologist Frank Taylor, and several of their predecessors who proposed “mobilist” ideas, he manages to string together brief descriptions of the contributions of (among others) German mineralogist Abraham Gottlob Werner, British geologists James Hutten and John Playfair, British engineer William Smith, British geologist Charles Lyell, American geologists James Hall and James Dwight Dana, British volcanologist William Lowthian Green, American geologist Grove Karl Gilbert, French geologist Elie de Beaumont, British geologist and mathematician Osmond Fisher, American geologist Clarence Dutton, British mathematician and physicist Lord Kelvin, Austrian geologist Eduard Suess, French geologist Marcel Bertrand, and American geologist Thomas Chrowder Chamberlin. Moreover, Wood offers an interesting thesis about the revolution in the earth sciences. He claims that the real revolution was not the replacement of fixist views with the mobilist ones of sea floor spreading and plate tectonics, but rather the replacement of geology with the new discipline of the earth sciences in which geophysics and geochemistry play the central role.

    In the early 1980s, Germany started a new era of modern Antarctic research. The Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) was founded and important research platforms such as the German permanent station in Antarctica, today called Neumayer III, and the research icebreaker Polarstern were installed. The research primarily focused on the Atlantic sector of the Southern Ocean. In parallel, the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) started a priority program `Antarctic Research' (since 2003 called SPP-1158) to foster and intensify the cooperation between scientists from different German universities and the AWI as well as other institutes involved in polar research. Here, we review the main findings in meteorology and oceanography of the last decade, funded by the priority program. The paper presents field observations and modelling efforts, extending from the stratosphere to the deep ocean. The research spans a large range of temporal and spatial scales, including the interaction of both climate components. In particular, radiative processes, the interaction of the changing ozone layer with large-scale atmospheric circulations, and changes in the sea ice cover are discussed. Climate and weather forecast models provide an insight into the water cycle and the climate change signals associated with synoptic cyclones. Investigations of the atmospheric boundary layer focus on the interaction between atmosphere, sea ice and ocean in the vicinity of polynyas and leads. The chapters dedicated to polar oceanography review the interaction between the ocean and ice shelves with regard to the freshwater input and discuss the changes in water mass characteristics, ventilation and formation rates, crucial for the deepest limb of the global, climate-relevant meridional overturning circulation. They also highlight the associated storage of anthropogenic carbon as well as the cycling of carbon, nutrients and trace metals

    Fracture toughness is a material parameter describing the resistance of a pre-existing defect in a body to further crack extension. The fracture toughness of glacial ice as a function of density is important for modeling efforts aspire to predict calving behavior. In the presented experiments this fracture toughness is measured using an ice core from Kohnen Station, Dronning Maud Land, Antarctica. The samples were sawed in an ice lab at the Alfred Wegener Institute in Bremerhaven at -20°C and had the dimensions of standard test samples with thickness 14 mm, width 28 mm and length 126 mm. The samples originate from a depth of 94.6 m to 96 m. The grain size of the samples was also identified. The grain size was found to be rather uniform. The critical fracture toughness is determined in a four-point bending approach using single edge V-notch beam samples. The initial notch length was around 2.5 mm and was prepared using a drilling machine. The experimental setup was designed at the Institute of Materials Science at Darmstadt. In this setup the force increases linearly, until the maximum force is reached, where the specific sample fractures. This procedure was done in an ice lab with a temperature of -15°C. The equations to calculate the fracture toughness for pure bending are derived from an elastic stress analysis and are given as a standard test method to detect the fracture toughness. An X-ray computer tomography (CT scanner) was used to determine the ice core densities. The tests cover densities from 843 kg m-3 to 871 kg m-3. Thereby the influence of the fracture toughness on the density was analyzed and compared to previous investigations of this material parameter. Finally the dependence of the measured toughness on thickness, width, and position in the core cross-section was investigated.

  5. A Query Language for Handling Big Observation Data Sets in the Sensor Web

    The Sensor Web provides a framework for the standardized Web-based sharing of environmental observations and sensor metadata. While the issue of varying data formats and protocols is addressed by these standards, the fast growing size of observational data is imposing new challenges for the application of these standards. Most solutions for handling big observational datasets currently focus on remote sensing applications, while big in-situ datasets relying on vector features still lack a solid approach. Conventional Sensor Web technologies may not be adequate, as the sheer size of the data transmitted and the amount of metadata accumulated may render traditional OGC Sensor Observation Services (SOS) unusable. Besides novel approaches to store and process observation data in place, e.g. by harnessing big data technologies from mainstream IT, the access layer has to be amended to utilize and integrate these large observational data archives into applications and to enable analysis. For this, an extension to the SOS will be discussed that establishes a query language to dynamically process and filter observations at storage level, similar to the OGC Web Coverage Service (WCS) and it's Web Coverage Processing Service (WCPS) extension. This will enable applications to request e.g. spatial or temporal aggregated data sets in a resolution it is able to display or it requires. The approach will be developed and implemented in cooperation with the The Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research whose catalogue of data compromises marine observations of physical, chemical and biological phenomena from a wide variety of sensors, including mobile (like research vessels, aircrafts or underwater vehicles) and stationary (like buoys or research stations). Observations are made with a high temporal resolution and the resulting time series may span multiple decades.

    smaller scale surveys - getting close to industry standards - targeted specific geological questions, the reconnaissance type of aerogeophysical projects continued in Dronning Maud Land, now in close cooperation with the Alfred-Wegener-Institute (AWI). This very successful cooperation between the two German institutions - both working continuously in the polar regions - was already established in Arctic projects, namely in northern Greenland. Also, since the late 1990's BGR conducted together with Canada airborne surveys as part of PMAP (Polar Margins Aeromagnetic Program), thematically linked to the predominantly geological CASE (Circum Arctic Structural Events) program of BGR. A joint project of GSC (Geological Survey of Canada) and BGR in the Nares Strait was a highlight of combined geological and aeromagnetic research addressing the still widely discussed Wegener fault between Greenland and Ellesmere Island and the extent of tertiary basins in the Nares Strait itself. BGR intends to continue its successful combined geological-geophysical work in both polar regions. The increasing logistic and financial challenges to work in these extreme areas will demand not only a continuation but an intensification of national and international collaboration.

    1984-11-09

    Freud never admitted to himself that he possessed a greater-than-average sense of ambition, which manifested itself in dreams, malachievement and priority problems. A completely new picture of Freud arises from such a perspective. Freud experienced childhood trauma in the form of his relationship with his nephew, John, in whom both an intimate friend and hated enemy were incorporated. This experience left a life-long impression which predetermined the neurotic element in Freud's relationship with men. Freud's own interpretation being that he had been betrayed by Breuer, Fliess, Adler and Jung. That is why the sentencing of his Uncle Joseph to a term of imprisonment had such far-reaching consequences for Freud. A further noteworthy observation is the close connection between ambition and death wishes and also between ambition and guilt feelings. Who, after all, likes to admit to harbouring such feelings? It appeared necessary to investigate the extent to which Freud's excessive ambition influenced his relationships with Breuer, Fliess and Adler. Freud was never prepared to recognize that Adler's contribution consisted of revealing the importance of the natural laws governing those layers of the psyche nearer to the conscious. The picture of the whole person emerges only by a combination of psychoanalysis and individual psychology.

    The Antarctic geomagnetics' community remains very active in crustal anomaly mapping. More than 1.5 million line-km of new air- and shipborne data have been acquired over the past decade by the international community in Antarctica. These new data together with surveys that previously were not in the public domain significantly upgrade the ADMAP compilation. Aeromagnetic flights over East Antarctica have been concentrated in the Transantarctic Mountains, the Prince Charles Mountains - Lambert Glacier area, and western Dronning Maud Land (DML) — Coats Land. Additionally, surveys were conducted over Lake Vostok and the western part of Marie Byrd Land by the US Support Office for Aerogeophysical Research projects and over the Amundsen Sea Embayment during the austral summer of 2004/2005 by a collaborative US/UK aerogeophysical campaign. New aeromagnetic data over the Gamburtsev Subglacial Mountains (120,000 line-km), acquired within the IPY Antarctica's Gamburtsev Province project reveal fundamental geologic features beneath the East Antarctic Ice sheet critical to understanding Precambrian continental growth processes. Roughly 100,000 line-km of magnetic data obtained within the International Collaboration for Exploration of the Cryosphere through Aerogeophysical Profiling promises to shed light on subglacial lithology and identify crustal boundaries for the central Antarctic Plate. Since the 1996/97 season, the Alfred Wegener Institute has collected 90,000 km of aeromagnetic data along a 1200 km long segment of the East Antarctic coast over western DML. Recent cruises by Australian, German, Japanese, Russian, British, and American researchers have contributed to long-standing studies of the Antarctic continental margin. Along the continental margin of East Antarctica west of Maud Rise to the George V Coast of Victoria Land, the Russian Polar Marine Geological Research Expedition and Geoscience Australia obtained 80,000 and 20,000 line-km, respectively, of

    2016 IBRV ARAON Arctic Cruise Leg-2, Expedition ARA07C was a multidisciplinary undertaking carried out in the East Siberian Sea (ESS) from August 25 to September 10, 2016. The program was conducted as a collaboration between the Korea Polar Research Institute (KOPRI), P.P. Shirshov Institute of Oceanology (IORAS), and Alfred Wegener Institute (AWI). During this expedition, the multi-channel seismic (MCS) data were acquired on the continental shelf and the upper slope of the ESS, totaling 3 lines with 660 line-kilometers. The continental shelf of ESS is one of the widest shelf seas in the world and it is believed to cover the largest area of sub-sea permafrost in the Arctic. According to the present knowledge of the glacial history of the western Arctic Ocean, it is likely that during the LGM with a sea level approximately 120 m below present, the entire shelf area of the ESS was exposed to very cold air temperatures so that thick permafrost should have formed. Indeed, in water depths shallower than 80 m, sub-bottom profiles in the ESS recorded from the shelf edge to a latitude of 74°30' N in 60 m water depth exhibited acoustic facies, suggesting that at least relicts of submarine permafrost are present. In order to identify the existence and/or non-existence of subsea permafrost in our study area, we analyze the MCS data using the Laplace domain full waveform inversion (FWI). In case of the Canadian continental shelf of the Beaufort Sea, subsea permafrost has high seismic velocity values (over 2.6 km/sec) and strong refraction events were found in the MCS shotgathers. However, in the EES our proposed P-wave velocity models derived from FWI have neither found high velocity structures (over 2.6 km/sec) nor indicate strong refraction events by subsea permafrost. Instead, in 300 m depth below sea floor higher P-wave velocity structures (1.8 2.2 km/s) than normal subsea sediment layers were found, which are interpreted as cemented strata by glaciation activities.

    A long-standing collaboration between Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) and the Federal Institute for Geosciences and Natural Resources (BGR) aims to investigate the sub-ice crustal architecture and tectonic evolution of East Antarctica. Its main emphasis is on Dronning Maud Land (DML). During the austral summers 2014 and 2015, ca. 40.000 line kilometre of new magnetic, gravity and ice-penetrating radar data were collected with 10 km line spacing. Here, we report on magnetic anomaly data to the east and south of Sør Rondane (eastern DML), analysed with several filtering techniques. These data are integrated with exposure information from Sør Rondane, the Belgica Mts., and the Yamato Mts.. The study area covers the eastern part of a major, recently revealed Early Neoproterozoic juvenile crustal block, the Tonian Oceanic Arc Super Terrane (TOAST). The western extent of the TOAST is well defined by the Forster Magnetic Anomaly and characterized by a province of subdued SE-striking parallel positive magnetic anomalies in the mostly ice-covered region of south-eastern DML (the SE DML province). Geological investigations showed that this area can be correlated with exposures in Sør Rondane and scattered nunataks west of it. U-Pb ages of ca. 1000-900 Ma, are documented from zircons of gabbro-trondhjemite-tonalite-granodiorite (GTTG) suites in both areas. Further, geochemical analyses prove a juvenile character of the GTTGs, which are interpreted as oceanic arc complexes. Glacial drift from southern Sør Rondane points to an inland continuation of the TOAST, so far of unknown dimensions. The new magnetic data constrain the southern and eastern minimum extent of the TOAST, which we think has a minimum area of 450.000 km2. The spatial extent of this major juvenile crustal province has major significance for the tectonic reconstruction of East Antarctica and its involvement in Rodinia since it is suggested having evolved

    The Canadian Network on Aerosols and Climate: Addressing Key Uncertainties in Remote Canadian Regions (or NETCARE) was established in 2013 to study the interactions between aerosols, chemistry, clouds and climate. The network brings together Canadian academic and government researchers, along with key international collaborators. Attention is being given to observations and modeling of Arctic aerosol, with the goal to understand underlying processes and so improve predictions of aerosol climate forcing. Motivation to understand the summer Arctic atmosphere comes from the retreat of summer sea ice and associated increase in marine influence. To address these goals, a suite of measurements was conducted from two platforms in summer 2014 in the Canadian Arctic, i.e. an aircraft-based campaign on the Alfred Wegener Institute POLAR 6 and an ocean-based campaign from the CGCS Amundsen icebreaker. NETCARE-POLAR was based out of Resolute Bay, Nunavut during an initial period of little transport and cloud-free conditions and a later period characterized by more transport with potentially biomass burning influence. Measurements included particle and cloud droplet numbers and size distributions, aerosol composition, cloud nuclei, and levels of gaseous tracers. Ultrafine particle events were more frequently observed in the marine boundary layer than above, with particle growth observed in some cases to cloud condensation nucleus sizes. The influence of biological processes on atmospheric constituents was also assessed from the ship during NETCARE-AMUNDSEN, as indicated by high measured levels of gaseous ammonia, DMS and oxygenated VOCs, as well as isolated particle formation and growth episodes. The cruise took place in Baffin Bay and through the Canadian archipelago. Interpretation of the observations from both campaigns is enhanced through the use of chemical transport and particle dispersion models. This talk will provide an overview of NETCARE Arctic observational and

    Permafrost-affected soils of the northern hemisphere have accumulated large pools of organic carbon (OC) since continuous low temperatures in the permafrost prevented organic carbon decomposition. According to recent estimates these soils contain 1670 Pg of OC, or about 2.5-times the carbon within the global vegetation. Rising arctic temperatures will result in increased permafrost thawing resulting in a mobilization of formerly frozen OC. The degradation of the newly available OC will result in an increased formation of trace gases such as methane and carbon dioxide which can be released to the atmosphere. Rising trace gas concentrations due to permafrost thawing would thereby form a positive feedback on climate warming. CarboPerm, is a joint German-Russian research project funded by the German Federal Ministry of Education and Research. It comprises multi-disciplinary investigations on the formation, turnover and release of OC in Siberian permafrost. It aims to gain increased understanding of how permafrost-affected landscapes will respond to global warming and how this response will influence the local, regional and global trace gas balance. Permafrost scientists from Russia and Germany will work together at different key sites in the Siberian Arctic. These sites are: the coast and islands at the Dmitry Laptev Strait, the Lena River Delta, and the Kolyma lowlands close to Cherskii. The scientific work packages comprise studies on (i) the origin, properties, and dynamics of fossil carbon, (ii) the age and quality of organic matter, (iii) the recent carbon dynamics in permafrost landscapes, (iv) the microbial transformation of organic carbon in permafrost, and (v) process-driven modeling of soil carbon dynamics in permafrost areas. The coordination will be at the University of Hamburg (scientific), the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research in Potsdam (logistic) and the Arctic and Antarctic Research Institute in St. Petersburg

  7. Reconciling Paleomagnetism and Pangea

    Outside of the realm of paleomagnetic studies, it has been a long held tenet that Pangea amalgamated into and disseminated from essentially the same paleogeography, the conventional Pangea reconstruction of Alfred Wegener. There is widespread geologic and geophysical support for this re-assembly during the Late Triassic-Early Jurassic, but global paleomagnetic data have been repeatedly shown to be incompatible with this reconstruction for pre-Late Triassic time. This discrepancy, which has endured from the late 1950's to the present day, has developed into a fundamental enigma of late Paleozoic-early Mesozoic paleomagnetism. The problem stems from a large disparity in the apparent polar wander paths (APWPs) of Laurussia and Gondwana when the landmasses are restored to the conventional paleogeography. If the APWPs are made to coincide while the conventional fit is maintained, a substantial crustal misfit results; a continental overlap of approximately 10° latitude (1000+ km) occurs between Laurussia and Gondwana. To resolve this problem, alternative Pangea reconstructions have been built to accommodate the late Paleozoic-early Mesozoic paleomagnetic data, but these invariably require large-scale shearing between Laurussia and Gondwana to reach the conventional Pangea re-assembly, from which it is unanimously agreed that the Atlantic Ocean opened in the Jurassic. Evidence for a megashear between these landmasses is critically lacking. Another proposed solution invokes time-dependent non-dipole fields, but challenges the working assumption that the geomagnetic field has effectively been a geocentric axial dipole through the Phanerozoic. The final alternative is that the problem is a manifestation of artifacts/contamination in the paleomagnetic data. Previous investigations of this last hypothesis have demonstrated its theoretical plausibility, but lacked the exhaustive analysis of global paleomagnetic data necessary to assuredly dispel the problem as an enduring data

    To improve our understanding of Arctic mixed-phase clouds a series of airborne research campaigns has been initiated by a collaboration of German research institutes. Clouds in areas dominated by a close sea-ice cover were observed during the research campaign Vertical distribution of ice in Arctic mixed-phase clouds (VERDI, April/May 2012) and the Radiation-Aerosol-Cloud Experiment in the Arctic Circle (RACEPAC, April/May 2014) which both were based in Inuvik, Canada. The aircraft (Polar 5 & 6, Basler BT-67) operated by the Alfred Wegener Institute for Polar and Marine Research, Germany did cover a wide area above the Canadian Beaufort with in total 149 flight hours (62h during VERDI, 87h during RACEPAC). For May/June 2017 a third campaign ACLOUD (Arctic Clouds - Characterization of Ice, aerosol Particles and Energy fluxes) with base in Svalbard is planned within the Transregional Collaborative Research Centre TR 172 ArctiC Amplification: Climate Relevant Atmospheric and SurfaCe Processes, and Feedback Mechanisms (AC)3 to investigate Arctic clouds in the transition zone between open ocean and sea ice. The aim of all campaigns is to combine remote sensing and in-situ cloud, aerosol and trace gas measurements to investigate interactions between radiation, cloud and aerosol particles. While during VERDI remote sensing and in-situ measurements were performed by one aircraft subsequently, for RACEPAC and ACLOUD two identical aircraft are coordinated at different altitudes to horizontally collocate both remote sensing and in-situ measurements. The campaign showed that in this way radiative and microphysical processes in the clouds can by studied more reliably and remote sensing methods can be validated efficiently. Here we will illustrate the scientific strategy of the projects including the progress in instrumentation. Differences in the general synoptic and sea ice situation and related changes in cloud properties at the different locations and seasons will be

    The Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) is a key international flagship initiative under the auspices of the International Arctic Science Committee (IASC). The main aim of MOSAiC is to improve our understanding of the functioning of the Arctic coupled system with a complex interplay between processes in the atmosphere, ocean, sea ice and ecosystem coupled through bio-geochemical interactions. The main objective of MOSAiC is to develop a better understanding of these important coupled-system processes so they can be more accurately represented in regional- and global-scale weather- and climate models. Observations covering a full annual cycle over the Arctic Ocean of many critical parameters such as cloud properties, surface energy fluxes, atmospheric aerosols, small-scale sea-ice and oceanic processes, biological feedbacks with the sea-ice ice and ocean, and others have never been made in the central Arctic in all seasons, and certainly not in a coupled system fashion. The main scientific goals focus on data assimilation for numerical weather prediction models, improved sea ice forecasts and climate models, ground truth for satellite remote sensing, energy budget and fluxes through interfaces, sources, sinks and cycles of chemical species, boundary layer processes, habitat conditions and primary productivity and stakeholder services. The MOSAiC Observatory will be deployed in, and drift with, the Arctic sea-ice pack for a full annual cycle, starting in fall 2019 and ending in fall 2020. Initial drift plans are to start in the newly forming fall sea-ice in the East Siberian Sea and follow the Transpolar Drift. The German Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research will made a huge contribution with the icebreaker Polarstern to serve as the central drifting observatory for this year long drift, and the US Department of Energy has committed a comprehensive atmospheric measurement suite.

    The Dutch geologist Rein van Bemmelen was the greatest opponent of plate tectonics in The Netherlands. He lived and worked during an important period in the history of earth sciences. He had studied geology when Wegeners theory was introduced and enthusiastically received in the Netherlands and he worked as a geologists during the period in which, after Wegeners theory was rejected in The Netherlands, several Dutch geologists came with their own theories to explain the origin of continents and oceans and in which plate tectonics was introduced in The Netherlands. He had proposed his own theory, the undation theory, at the beginning of the 1930s and kept on developing it during the following years. He continued to do so until his death in 1983. The history of the undation theory thus sheds light on the history of geology in The Netherlands. I will trace the history of geology in The Netherlands using Rein van Bemmelen and his undation theory as a lens.

    In the early 1920s, the continental displacement theory of Wegener, latitude studies of Koppen and Wegener, and Argand's ideas on mountain building led to the first mobilistic paleogeography. In the 1930s and 1940s, many factors caused its general abandonment. Mobilism was revived in the 1950s and 1960s by measurements of long-term displacement of crustal blocks relative to each other (tectonic displacement) and to Earth's geographic pole (latitudinal displacement). Also, short-term or current displacements can now be measured. I briefly outline the categories of tectonic and current displacement and focus on latitudinal displacement. Integration of tectonic and latitudinal displacement in the early 1970s completed the new mobilistic paleogeography, in which the transformation of rock magnetization directions into paleopoles and latitudes and the finite rotation of spherical plates about pivot points play complementary roles; this new synthesis now provides a quantitative basis for studying long-term evolution of Earth's surface features and climate, the changing environments in which life evolves.

    The search for balance between humankind's civilisational aspirations and the durable protection of nature is conditioned by contemporaneous views of biotic nature. Of particular importance in this regard are physiocentric and physiological views that may be set against one another. The first of these was presented by Hans Jonas, the second by Lothar Schäfer. This paper does not confine itself to setting one view against the other, but rather sets minimum conditions for cooperation between their promoters in the interests of balance between the aspirations of the present generation and those of future generations. Both views of nature are in their own way conducive to a break with the illusion present in some areas of the modern natural sciences - that nature is a boundless area of are inexhaustible resources.

    Nonlinear Ocean Waves and the Inverse Scattering Transform is a comprehensive examination of ocean waves built upon the theory of nonlinear Fourier analysis. The renowned author, Alfred R. Osborne, is perhaps best known for the discovery of internal solitons in the Andaman Sea during the 1970s. In this book, he provides an extensive treatment of nonlinear water waves based on a nonlinear spectral theory known as the inverse scattering transform. The writing is exceptional throughout the book, which is particularly useful in explaining some of the more difficult mathematical concepts.  Review info: Nonlinear Ocean Waves and the Inverse Scattering Transform.

    Inspired by the work of Newton, Darwin, and Wegener, this paper tracks the drivers and dynamics that have shaped the growth of hydrological understanding over the last century. On the basis of an interpretation of this history, the paper then speculates about what kind of future is in store for hydrology and how we can better prepare for it. The historical narrative underpinning this analysis indicates that progress in hydrological understanding is brought about by changing societal needs and technological opportunities: new ideas are generated by hydrologists through addressing societal needs with the technologies of their time. We suggest that progress in hydrological understanding over the last century has expressed itself through repeated cycles of euphoria and disenchantment, which have served as stimuli for the progress. The progress, for it to happen, also needed inspirational leaders as well as a supportive scientific community that provided the backdrop to major advances in the field. The paper concludes that, in a similar way to how Newton, Darwin, and Wegener conducted their research, hydrology too can benefit from synthesis activities aimed at "connecting the dots."

    The early history of leukemia reaches back 200 years. In 1811, Peter Cullen defined a case of splenitis acutus with unexplainable milky blood. Alfred Velpeau defined the leukemia associated symptoms, and observed pus in the blood vessels (1825). Alfred Donné detected a maturation arrest of the white blood cells (1844). John Bennett named the disease leucocythemia, based on the microscopic accumulation of purulent leucocytes (1845). That same year, Rudolf Virchow defined a reversed white and red blood cell balance. He introduced the disease as leukämie in 1847. Henry Fuller performed the first microscopic diagnose of a leukemic patient during life (1846). This gradual process brought us towards our current understanding of this complex disease. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Due to a complex set of feedback processes collectively known as "polar amplification", the Arctic realm is expected to experience a greater-than-average response to global climate forcing. The cascades of feedback processes that connect the Arctic cryosphere, ocean and atmosphere remain incompletely constrained by observations and theory and are difficult to simulate in climate models. Our capacity to predict the future of the region and assess the impacts of Arctic change processes on global and regional environments hinges on the availability of interdisciplinary experts with strong international experience and understanding of the science/society interface. This is the basis of the International Research Training Group "Processes and impacts of climate change in the North Atlantic Ocean and the Canadian Arctic - ArcTrain", which was initiated in 2013. ArcTrain aims to educate PhD students in an interdisciplinary environment that combines paleoclimatology, physical oceanography, remote sensing and glaciology with comprehensive Earth system modelling, including sea-ice and ice-sheet components. The qualification program for the PhD students includes joint supervision, mandatory research residences at partner institutions, field courses on land and on sea (Floating University), annual meetings and training workshops and a challenging structured training in expert skills and transferrable skills. Its aim is to enhance the career prospects and employability of the graduates in a challenging international job market across academic and applied sectors. ArcTrain is a collaborative project at the University of Bremen and the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven. The German part of the project is designed to continue for nine years and educate three cohorts of twelve PhD students each.

    The Arctic Ocean has been in the focus of many studies during recent years, investigating the state, the causes and the implications of the observed rapid transition towards a thinner and younger sea-ice cover. However, consistent observational datasets of sea ice, ocean and atmosphere are still sparse due to the limited accessibility and harsh environmental conditions. One important tool to fill this gap has become more and more feasible during recent years: autonomous, ice-tethered measurement platforms (buoys). These drifting instruments independently transmit their data via satellites, and enable observations over larger areas and over longer time periods than manned expeditions, even throughout the winter. One aim of the newly established FRAM (FRontiers in Arctic marine Monitoring) infrastructure program at the Alfred-Wegener-Institute is to realize and maintain an interdisciplinary network of buoys in the Arctic Ocean, contributing to an integrated, Arctic-wide observatory. The additional buoy infrastructure, ship-time, and developments provided by FRAM are critical elements in the ongoing international effort to fill the large data gaps in a rapidly changing Arctic Ocean. Our focus is the particularly underrepresented Eurasian Basin. Types of instruments range from snow depth beacons and ice mass balance buoys for monitoring ice growth and snow accumulation, over radiation and weather stations for energy budget estimates, to ice-tethered profiling systems for upper ocean monitoring. Further, development of new bio-optical and biogeochemical buoys is expected to enhance our understanding of bio-physical processes associated with Arctic sea ice. The first set of FRAM buoys was deployed in September 2015 from RV Polarstern. All datasets are publicly available on dedicated web portals. Near real time data are reported into international initiatives, such as the Global Telecommunication System (GTS) and the International Arctic Buoy Programme (IABP). The

    All living beings on Earth, from bacteria to humans, are connected through descent from common ancestors and represent the summation of their corresponding, ca. 3500 million year long evolutionary history. However, the evolution of phenotypic features is not predictable, and biologists no longer use terms such as "primitive" or "perfect organisms". Despite these insights, the Bible-based concept of the so-called "ladder of life" or Scala Naturae, i.e., the idea that all living beings can be viewed as representing various degrees of "perfection", with humans at the very top of this biological hierarchy, was popular among naturalists until ca. 1850 (Charles Bonnet, Jean Lamarck and others). Charles Darwin is usually credited with the establishment of a branched evolutionary "Tree of Life". This insight of 1859 was based on his now firmly corroborated proposals of common ancestry and natural selection. In this article I argue that Darwin was still influenced by "ladder thinking", a theological view that prevailed throughout the 19th century and is also part of Ernst Haeckel's famous Oak tree (of Life) of 1866, which is, like Darwin's scheme, static. In 1910, Constantin Mereschkowsky proposed an alternative, "anti-selectionist" concept of biological evolution, which became known as the symbiogenesis-theory. According to the symbiogenesis-scenario, eukaryotic cells evolved on a static Earth from archaic prokaryotes via the fusion and subsequent cooperation of certain microbes. In 1929, Alfred Wegener published his theory of continental drift, which was later corroborated, modified and extended. The resulting theory of plate tectonics is now the principal organizing concept of geology. Over millions of years, plate tectonics and hence the "dynamic Earth" has caused destructive volcanic eruptions and earthquakes. At the same time, it created mountain ranges, deep oceans, novel freshwater habitats, and deserts. As a result, these geologic processes destroyed numerous

    The World Radiation Monitoring Center (WRMC) is the central archive of the Baseline Surface Radiation Network (BSRN). The BSRN was initiated by the World Climate Research Programme (WCRP) Working Group on Radiative Fluxes and began operations in 1992. One of its aims is to provide short and long-wave surface radiation fluxes of the best possible quality to support the research projects of the WCRP and other scientific projects. The high quality, uniform and consistent measurements of the BSRN network can be used to monitor the short- and long-wave radiative components and their changes with the best methods currently available, to validate and evaluate satellite-based estimates of the surface radiative fluxes, and to verify the results of global climate models. In 1992 the BSRN/WRMC started at ETH Zurich, Switzerland with 9 stations. Since 2007 the archive is hosted by the Alfred-Wegener-Institut (AWI) in Bremerhaven, Germany (http://www.bsrn.awi.de/) and comprises a network of currently 59 stations in contrasting climatic zones, covering a latitude range from 80°N to 90°S. Of the 59 stations, 23 offer the complete radiation budget (down- and upwelling short- and long-wave data). In addition to the ftp-service access instituted at ETH Zurich, the archive at AWI offers data access via PANGAEA - Data Publisher for Earth & Environmental Science (https://www.pangaea.de). PANGAEA guarantees the long-term availability of its content through a commitment of the operating institutions. Within PANGAEA, the metadata of the stations are freely available.

  9. From the scala naturae to the symbiogenetic and dynamic tree of life

    PubMed Central

    2011-01-01

    All living beings on Earth, from bacteria to humans, are connected through descent from common ancestors and represent the summation of their corresponding, ca. 3500 million year long evolutionary history. However, the evolution of phenotypic features is not predictable, and biologists no longer use terms such as "primitive" or "perfect organisms". Despite these insights, the Bible-based concept of the so-called "ladder of life" or Scala Naturae, i.e., the idea that all living beings can be viewed as representing various degrees of "perfection", with humans at the very top of this biological hierarchy, was popular among naturalists until ca. 1850 (Charles Bonnet, Jean Lamarck and others). Charles Darwin is usually credited with the establishment of a branched evolutionary "Tree of Life". This insight of 1859 was based on his now firmly corroborated proposals of common ancestry and natural selection. In this article I argue that Darwin was still influenced by "ladder thinking", a theological view that prevailed throughout the 19th century and is also part of Ernst Haeckel's famous Oak tree (of Life) of 1866, which is, like Darwin's scheme, static. In 1910, Constantin Mereschkowsky proposed an alternative, "anti-selectionist" concept of biological evolution, which became known as the symbiogenesis-theory. According to the symbiogenesis-scenario, eukaryotic cells evolved on a static Earth from archaic prokaryotes via the fusion and subsequent cooperation of certain microbes. In 1929, Alfred Wegener published his theory of continental drift, which was later corroborated, modified and extended. The resulting theory of plate tectonics is now the principal organizing concept of geology. Over millions of years, plate tectonics and hence the "dynamic Earth" has caused destructive volcanic eruptions and earthquakes. At the same time, it created mountain ranges, deep oceans, novel freshwater habitats, and deserts. As a result, these geologic processes destroyed numerous

    This digital database is the product of collaboration between the U.S. Geological Survey, the Geophysical Institute at the University of Alaska, Fairbanks; the Los Altos Hills Foothill College GeoSpatial Technology Certificate Program; the Alfred Wegener Institute for Polar and Marine Research, Potsdam, Germany; and the Institute of Physical Chemical and Biological Problems in Soil Science of the Russian Academy of Sciences. The primary goal for creating this digital database is to enhance current estimates of soil organic carbon stored in deep permafrost, in particular the late Pleistocene syngenetic ice-rich permafrost deposits of the Yedoma Suite. Previous studies estimated that Yedoma deposits cover about 1 million square kilometers of a large region in central and eastern Siberia, but these estimates generally are based on maps with scales smaller than 1:10,000,000. Taking into account this large area, it was estimated that Yedoma may store as much as 500 petagrams of soil organic carbon, a large part of which is vulnerable to thaw and mobilization from thermokarst and erosion. To refine assessments of the spatial distribution of Yedoma deposits, we digitized 11 Russian Quaternary geologic maps. Our study focused on extracting geologic units interpreted by us as late Pleistocene ice-rich syngenetic Yedoma deposits based on lithology, ground ice conditions, stratigraphy, and geomorphological and spatial association. These Yedoma units then were merged into a single data layer across map tiles. The spatial database provides a useful update of the spatial distribution of this deposit for an approximately 2.32 million square kilometers land area in Siberia that will (1) serve as a core database for future refinements of Yedoma distribution in additional regions, and (2) provide a starting point to revise the size of deep but thaw-vulnerable permafrost carbon pools in the Arctic based on surface geology and the distribution of cryolithofacies types at high spatial

    Based on the jeopardy of devastating tsunamis and the unpredictability of such events, tsunami modelling as part of warning systems is still a contemporary topic. The tsunami group of Alfred Wegener Institute developed the simulation tool TsunAWI as contribution to the Early Warning System in Indonesia. Although the precomputed scenarios for this purpose qualify for satisfying deliverables, the study of further improvements continues. While TsunAWI is governed by the Shallow Water Equations, an extension of the model is based on a nonhydrostatic approach. At the arrival of a tsunami wave in coastal regions with rough bathymetry, the term containing the nonhydrostatic part of pressure, that is neglected in the original hydrostatic model, gains in importance. In consideration of this term, a better approximation of the wave is expected. Differences of hydrostatic and nonhydrostatic model results are contrasted in the standard benchmark problem of a solitary wave runup on a plane beach. The observation data provided by Titov and Synolakis (1995) serves as reference. The nonhydrostatic approach implies a set of equations that are similar to the Shallow Water Equations, so the variation of the code can be implemented on top. However, this additional routines cause a lot of issues you have to cope with. So far the computations of the model were purely explicit. In the nonhydrostatic version the determination of an additional unknown and the solution of a large sparse system of linear equations is necessary. The latter constitutes the lion's share of computing time and memory requirement. Since the corresponding matrix is only symmetric in structure and not in values, an iterative Krylov Subspace Method is used, in particular the restarted Generalized Minimal Residual Algorithm GMRES(m). With regard to optimization, we present a comparison of several combinations of sequential and parallel preconditioning techniques respective number of iterations and setup

    The Antarctic Ross Sea is one of the key regions for polar research activities. Research stations from several countries located at the coast are the base for inland expeditions. Even in the austral summer, the Ross Sea is party covered with drifting ice fields; this requires an icebreaker for all marine explorations. Therefore, large geophysical surveys in the Ross Sea are difficult. But the area is of special interest for seismologists: The Terror Rift in the western Ross Sea is a prominent neotectonic structure of the West Antarctic Rift System (WARS). It is located near the coast in the Victoria Land Basin and extends parallel to the Transantarctic Mountains. The rifting processes and the accompanying active onshore volcanism lead to increased seismicity in the region. The annual waxing and waning of the sea-ice and the dynamics of the large Ross Ice Shelf and nearby glaciers generate additional seismic signals. Investigation on seismological activities associated with the WARS and the cryogenic signals simultaneously would give us an unprecedented opportunity to have a better understanding of the Evolution of the WARS (EWARS) and the rapid change in the cryospheric environment nearby. The Korea Polar Research Institute (KOPRI) and the Alfred-Wegener-Institut (AWI) have conducted a pilot study off the Korean Jang Bogo research station in the Terra Nova Bay by developing a collaborative research program (EWARS) since 2011 to explore seismicity and seismic noise in this region. Four broadband ocean-bottom seismometers (OBS) from the German DEPAS pool were deployed in January 2012 with the Korean research icebreaker RV Araon. Three instruments could successfully be recovered after 13 months, the fourth OBS was not accessible due to local sea-ice coverage. We have successfully completed a second recovery operation in January 2014. All stations recorded data of good quality, one station stopped after 8 months due to a recorder error. The OBS recovered in 2014

    The Arctic is warming much faster than any other place in the world and undergoes a rapid change dominated by a changing climate in this region. The impact of polluted air masses traveling to the Arctic from various remote sources significantly contributes to the observed climate change, in contrast there are additional local emission sources contributing to the level of pollutants (trace gases and aerosol). Processes affecting the emission and transport of these pollutants are not well understood and need to be further investigated. We present aircraft based trace gas measurements in the Arctic during RACEPAC (2014) and NETCARE (2014 and 2015) with the Polar 6 aircraft of Alfred Wegener Institute (AWI) covering an area from 134°W to 17°W and 68°N to 83°N. We focus on cloud, aerosol and general transport processes of polluted air masses into the high Arctic. Based on CO and CO2 measurements and kinematic 10-day back trajectories we analyze the transport regimes prevalent during spring (RACEPAC 2014 and NETCARE 2015) and summer (NETCARE 2014) in the observed region. Whereas the eastern part of the Canadian Arctic is affected by air masses with their origin in Asia, in the central and western parts of the Canadian and European Arctic air masses from North America are predominant at the time of the measurement. In general the more northern parts of the Arctic were relatively unaffected by pollution from mid-latitudes since air masses mostly travel within the polar dome, being quite isolated. Associated mixing ratios of CO and CO2 fit into the seasonal cycle observed at NOAA ground stations throughout the Arctic, but show a more mid-latitudinal characteristic at higher altitudes. The transition is remarkably sharp and allows for a chemical definition of the polar dome. At low altitudes, synoptic disturbances transport polluted air masses from mid-latitudes into regions of the polar dome. These air masses contribute to the Arctic pollution background, but also

    Knowledge transfer and dialogue processes in the field of climate science have captured intensive attention in recent years as being an important part of research activities. Therefore, the demand and pressure to develop a set of indicators for the evaluation of different activities in this field have increased, too. Research institutes are being asked more and more to build up structures in order to map these activities and, thus, are obliged to demonstrate the success of these efforts. This paper aims to serve as an input to stimulate further reflection on the field of evaluation of knowledge transfer and dialogue processes in the context of climate sciences. The work performed in this paper is embedded in the efforts of the German Helmholtz Association in the research field of earth and environment and is driven by the need to apply suitable indicators for knowledge transfer and dialogue processes in climate research center evaluations. We carry out a comparative analysis of three long-term activities and derive a set of indicators for measuring their output and outcome by balancing the wide diversity and range of activity contents as well as the different tools to realize them. The case examples are based on activities which are part of the regional Helmholtz Climate Initiative Regional Climate Change (REKLIM) and the Climate Office for Polar Regions and Sea Level Rise at the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research. Both institutional units have been working on a wide range of different knowledge transfer and dialogue processes since 2008/2009. We demonstrate that indicators for the evaluation must be based on the unique objectives of the individual activities and the framework they are embedded in (e.g., research foci which provide the background for the performed knowledge transfer and dialogue processes) but can partly be classified in a principle two-dimensional scheme. This scheme might serve as a usable basis for

    2001-12-01

    As a scientific research agency, the U.S. Geological Survey (USGS) is in an ideal position to provide scientific information and resources to educators. The USGS is not a curriculum developer, nor an expert in pedagogy, yet the USGS does have a wealth of scientific information on subjects such as fossils, geologic time, biological resources and plate tectonics that naturally come in to play in the teaching of evolution. Among USGS resources are the general interest pamphlets Geologic Time, Dinosaurs: Facts And Fiction, Our Changing Continent, and Fossils Rocks, and Time, and its accompanying poster, Fossils Through Time. In addition to printed versions, the pamphlets are available at no cost on the Internet at http://pubs.usgs.gov/gip/. The popular booklet, This Dynamic Earth: The Story of Plate Tectonics, available at http://pubs.usgs.gov/publications/text/dynamic.html, touches on evolution-related subjects such as Alfred Wegener's use of fossils to develop his theory of continental drift, "polar" dinosaur fossils found in Australia, marine fossils in the rocks of the Himalayas, and the use of fossil ages to determine rates of plate motions. Paleontological research at the USGS is highlighted on the Internet at http://geology.er.usgs.gov/paleo/. The web site includes links to technical publications, profiles of scientists, a geologic time scale, a glossary, information on important fossil groups, and a list of non-USGS references on fossils: all very useful to educators. A wealth of biological information and data can be found in the National Biological Information Infrastructure (NBII), a multi-agency collaborative program led by the USGS. In addition to data on the Nation's biological resources, the NBII web site http://www.nbii.gov/ includes a section on systematics and scientific names (helpful for illustrating the evolutionary relationships among living organisms), and links to non-USGS curriculum materials.

    To examine the response of the Victorian State Trauma System to the February 2009 bushfires. A retrospective review of the strategic response required to treat patients with bushfire-related injury in the first 72 hours of the Victorian bushfires that began on 7 February 2009. Emergency department (ED) presentations and initial management of patients presenting to the state's adult burns centre (The Alfred Hospital [The Alfred]) were analysed, as well as injuries and deaths associated with the fires. There were 414 patients who presented to hospital EDs as a result of the bushfires. Patients were triaged at the emergency scene, at treatment centres and in hospital. National and statewide burns disaster plans were activated. Twenty-two patients with burns presented to the state's burns referral centres, of whom 18 were adults. Adult burns patients at The Alfred spent 48.7 hours in theatre in the first 72 hours. There were a further 390 bushfire-related ED presentations across the state in the first 72 hours. Most patients with serious burns were triaged to and managed at burns referral centres. Throughout the disaster, burns referral centres continued to have substantial surge capacity. Most bushfire victims either died, or survived with minor injuries. As a result of good prehospital triage and planning, the small number of patients with serious burns did not overload the acute health care system.

    The probability of multiple wind-storm events within a year is crucial to any (re)insurance company writing European wind business. Indeed, the volatility of losses is enhanced by the clustering of storms (cyclone families), as occurred in early 1990 (Daria, Vivian, Wiebke), December 1999 (Lothar, Martin) or December 2015 (Desmond, Eva, Frank), among others. In order to track winter extratropical cyclones, we use the maximum relative vorticity at 850 hPa of the new-released long-term ERA-20C reanalysis from the ECMWF since the beginning of the 20th Century until 2010. We develop an automatic procedure to define events. We then quantify the severity of each storm using loss and meteorological indices at country and Europe-wide level. Validation against market losses for the period 1970-2010 is undertaken before considering the severity and frequency of European windstorms for the 110 years period.

    to investigate the incidence of injuries in different vascular beds and the morphopathological changes in vessels in granulomatosis with polyangiitis. The morphopathological features of vascular injuries were investigated in 11 dead patients aged 16--74 years with granulomatosis with polyangiitis. Proliferative and destructive angiitis with predominant involvement of microcirculatory vessels and with development of necrosis-prone granulomas in their walls and perivascularly was established to underlie the clinical manifestations of granulomatosis with polyangiitis. The most typical localization of the pathologic process is the vessels of the upper respiratory tract, lungs, and kidneys. Cardiopulmonary and renal failures are causes of death in the majority of cases. It should be noted that the vessels of the heart, liver, and gastrointestinal tract are frequently involved in the pathological process. Vascular changes in these organs determine the clinical features of granulomatosis with polyangiitis and lead to a number of fatal complications. Granulomatosis with polyangiitis is a systemic disease with polymorphism of clinical manifestations, which requires in-depth analysis based on current precision patient examination methods, including a histopathological study.

  13. Coherent Control of Scattering Processes in Semiconductors

    Wehner, M. U.

    1998-03-01

    On a timescale which compares to the duration of single scattering events, the relaxation of optical excitations in semiconductors has to be described by the quantum kinetic theory. Instead of simple scattering rates this theory delivers a non-Markovian dephasing. Related memory effects have so far been observed for the case of electron-LO-phonon scattering in four-wave-mixing experiments on GaAs at T = 77 K using 15 fs pulses (L. Bányai, D.B. Tran Thoai, E. Reitsamer, H. Haug, D. Steinbach, M.U. Wehner, T. Marschner, M. Wegener and W. Stolz, Phys. Rev. Lett. 75), 2188 (1995). It is crucial for the quantum kinetic time regime that scattering processes must not be considered as completed and irreversibel. The reversibility of the scattering shortly after optical excitation is demonstrated in four-wave-mixing experiments using coherent control. By adjusting the relative phase of two phase-locked pulses, the non-Markovian phonon oscillations observed in Ref.1 can be either suppressed or amplified (M. U. Wehner, M. H. Ulm, D. S. Chemla and M. Wegener, Phys. Rev. Lett. submitted). The behavior of the coherently controlled scattering amplitude is discussed using a simple model Hamiltonian, which describes the variation of the phonon oscillations in amplitude and phase very well.

    The survival after renal transplantation of patients with antineutrophil cytoplasmic antibody (ANCA)-associated to systemic vasculitis is as good as in other diseases, although most of the reports are based on small numbers of patients. Furthermore, it is not known whether comorbidities (cardiovascular [CV] disease and cancer) are more frequent than in general population. We report our experience and the analysis of the published data on this topic. The outcome after transplantation in 49 patients with ANCA-associated small vessel vasculitis was compared with a control group. The relapse rate of vasculitis was 0.01 per patient per year. Comparison with the control patients revealed no difference in long-term outcome, CV mortality or incidence of malignancies. In the published literature, patients with ANCA at transplantation and with Wegener's granulomatosis are at greater risk of relapse. Taking our own results together with the review of the literature, we conclude that patient and graft survival rates compare favorably with those in control group that the recurrence rate is very low and that there is no increase in the incidence of cancer or in CV mortality. Patients with ANCA at transplantation and with Wegener's granulomatosis have a higher relapse rate. © 2013 John Wiley & Sons A/S.

    The case histories of two patients with cavitary pulmonary nodules and the findings at chest radiography are reviewed. The first patient had a connective tissue disease with features common to systematic lupus erythematosus and Wegener's granulomatosis. In the second patient the lung changes developed as part of a drug reaction to carbamezapine and/or phenytoin. The common denominator of the cavitating nodules is probably the presence of granulomas, developing as a sequela of pulmonary vasculitis.

  14. How does a tidal embayment morphodynamically react on sea level rise?

    NASA Astrophysics Data System (ADS)

    van der Wegen, Mick

    2010-05-01

    Conditions for (assumed) equilibrium in tidal embayments have been studied extensively in the past years with morphodynamic 1D models (Van Dongeren and De Vriend, 1994; Schuttelaars and de Swart, 1996, 2000; Lanzoni and Seminara, 2002) and 2D models (Hibma et al. [2003], Van der Wegen and Roelvink [2008]) Van der Wegen et al 2008). The current research addresses the impact of sea level rise on tidal embayments. Although effects of sea level rise may only become apparent after decades, the character of the embayment can change considerably. Examples are the (dis)appearance or re-allocation of intertidal flats, increased tidal resonance, shift from sediment export to import, deepening of channel area and other related (ecological) parameters. The research applies a 2D morphodynamic model (Delft3D) in an idealized environment. The model is based on the 2 D shallow water equations, the Engelund -Hansen transport formula and includes bed slope effects, drying and flooding procedures and an advanced morphodynamic update scheme (Roelvink 2006). The initial condition of the bathymetry is generated by 3000 years of morphodynamic calculations in a 80 km long and 2.5 km wide rectangular tidal embayment under constant M2 tidal forcing conditions (Van der Wegen and Roelvink [2008]). After this period sea level rise gradually developing towards a rate of 0.4 m/century is added to the boundary conditions. Model results describe development towards less intertidal area and a transition from an exporting system to a importing system. Model results are evaluated in terms of M2, M4 and M6 tidal constituents as well as against Vs/Vc (shoal volume over channel volume) versus a/h (amplitude over water depth) relationship as proposed by Friedrichs and Aubrey (1988). Although the model describes morphodynamic development in a strongly idealized environment the results can provide an excellent tool to systematically study the impact of sea level rise in tidal embayments as well as the time

    The clean and sensitive Arctic atmosphere is influenced by transport of air masses from lower latitudes that bring pollution in the form of aerosol particles and trace gases into the Arctic regions. However, the transport processes causing such pollution events are yet not sufficiently well understood. Here we report on results from the aircraft campaign NETCARE 2014 that took place in July 2014 in Resolute Bay, Nunavut (Canada) as part of the "Network on Climate and Aerosols: Addressing Key Uncertainties in Remote Canadian Environment" (NETCARE). These airborne measurements add to only a very few of such measurements conducted in the Arctic during the summertime. The instrumentation on board the research aircraft Polar 6 (operated by the Alfred Wegener Institute for Polar and Marine Research) included a large set of physico-chemical aerosol analysis instruments, several trace gas measurements and basic meteorological parameters. Here we focus on observed pollution events that caused elevated trace gas and aerosol concentrations in the summertime Canadian High Arctic between 50 and 3500 m. In order to better understand the chemical composition and the origin of those polluted air masses, we use single particle aerosol composition obtained using the Aircraft-based Laser Ablation Aerosol Mass Spectrometer (ALABAMA), combined with aerosol size distributions and number concentrations from an Optical Particle Counter as well as trace gas measurements of CO and CO2. CO and CO2 are important tracers to study pollution events, which are connected to anthropogenic and non-anthropogenic combustion processes, respectively biomass burning and fossil fuel combustion. The ALABAMA provides a detailed single particle aerosol composition analysis from which we identify different particle types like soot-, biomass burning-, organics-, diesel exhaust- and metallic particles. The measurements were compared to Lagrangian models like FLEXPART and LAGRANTO to find the pollution sources

    Recent advances in underwater imaging technology allow for the gathering of invaluable scientific information on seafloor ecosystems, such as direct in situ views of seabed habitats and quantitative data on the composition, diversity, abundance, and distribution of epibenthic fauna. The imaging approach has been extensively used within the research project DynAMo (Dynamics of Antarctic Marine Shelf Ecosystems) at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research Bremerhaven (AWI), which aimed to comparatively assess the pace and quality of the dynamics of Southern Ocean benthos. Within this framework, epibenthic spatial distribution patterns have been comparatively investigated in two regions in the Atlantic sector of the Southern Ocean: the shelf areas off the northern tip of the Antarctic Peninsula, representing a region with above-average warming of surface waters and sea-ice reduction, and the shelves of the eastern Weddell Sea as an example of a stable high-Antarctic marine environment that is not (yet) affected by climate change. The AWI Ocean Floor Observation System (OFOS) was used to collect seabed imagery during two cruises of the German research vessel Polarstern, ANT-XXIX/3 (PS81) to the Antarctic Peninsula from January to March 2013 and ANT-XXXI/2 (PS96) to the Weddell Sea from December 2015 to February 2016. Here, we report on the image and data collections gathered during these cruises. During PS81, OFOS was successfully deployed at a total of 31 stations at water depths between 29 and 784 m. At most stations, series of 500 to 530 pictures ( > 15 000 in total, each depicting a seabed area of approximately 3.45 m2 or 2.3 × 1.5 m) were taken along transects approximately 3.7 km in length. During PS96, OFOS was used at a total of 13 stations at water depths between 200 and 754 m, yielding series of 110 to 293 photos (2670 in total) along transects 0.9 to 2.6 km in length.

  1. Fully automatic adjoints: a robust and efficient mechanism for generating adjoint ocean models

    NASA Astrophysics Data System (ADS)

    Ham, D. A.; Farrell, P. E.; Funke, S. W.; Rognes, M. E.

    2012-04-01

    The problem of generating and maintaining adjoint models is sufficiently difficult that typically only the most advanced and well-resourced community ocean models achieve it. There are two current technologies which each suffer from their own limitations. Algorithmic differentiation, also called automatic differentiation, is employed by models such as the MITGCM [2] and the Alfred Wegener Institute model FESOM [3]. This technique is very difficult to apply to existing code, and requires a major initial investment to prepare the code for automatic adjoint generation. AD tools may also have difficulty with code employing modern software constructs such as derived data types. An alternative is to formulate the adjoint differential equation and to discretise this separately. This approach, known as the continuous adjoint and employed in ROMS [4], has the disadvantage that two different model code bases must be maintained and manually kept synchronised as the model develops. The discretisation of the continuous adjoint is not automatically consistent with that of the forward model, producing an additional source of error. The alternative presented here is to formulate the flow model in the high level language UFL (Unified Form Language) and to automatically generate the model using the software of the FEniCS project. In this approach it is the high level code specification which is differentiated, a task very similar to the formulation of the continuous adjoint [5]. However since the forward and adjoint models are generated automatically, the difficulty of maintaining them vanishes and the software engineering process is therefore robust. The scheduling and execution of the adjoint model, including the application of an appropriate checkpointing strategy is managed by libadjoint [1]. In contrast to the conventional algorithmic differentiation description of a model as a series of primitive mathematical operations, libadjoint employs a new abstraction of the simulation

    2009-01-01

    Currently, several different instruments are used to measure disease activity and extent in clinical trials of anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis, leading to division among investigative groups and difficulty comparing study results. An exercise comparing six different vasculitis instruments was performed. A total of 10 experienced vasculitis investigators from 5 countries scored 20 cases in the literature of Wegener granulomatosis or microscopic polyangiitis using 6 disease assessment tools: the Birmingham Vasculitis Activity Score (BVAS), The BVAS for Wegener granulomatosis (BVAS/WG), BVAS 2003, a Physician Global Assessment (PGA), the Disease Extent Index (DEI) and the Five Factor Score (FFS). Five cases were rescored by all raters. Reliability of the measures was extremely high (intraclass correlations for the six measures all = 0.98). Within each instrument, there were no significant differences or outliers among the scores from the 10 investigators. Test/retest reliability was high for each measure: range = 0.77 to 0.95. The scores of the five acute activity measures correlated extremely well with one another. Currently available tools for measuring disease extent and activity in ANCA-associated vasculitis are highly correlated and reliable. These results provide investigators with confidence to compare different clinical trial data and helps form common ground as international research groups develop new, improved and universally accepted vasculitis disease assessment instruments.

  3. A buried marine depositional sequence (Presumpscot FM. ) N. of the marine limit, Waterboro, Maine

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Morency, R.E.

    Subsurface investigations conducted in Waterboro, ME (York Co.) in connection with studies of two hazardous waste sites and a municipal water supply exploration project, have demonstrated that a laterally extensive sequence of marine deposits underlies surficial sediments mapped as non-esker ice contact glacio-fluvial deposits. The marine deposits consist of a fining-downwards sequence of grey, micaceous sands (fine to medium, grading down to a silty-fine sand), which grade downward into a thick ([plus minus] 30 feet) grey silt/clay unit, which itself shows a fining-downward trend. The stratigraphy is likely correlative to the Presumpscot Formation, as described by Bloom (1963). The bottommore » of the regressive marine sequence is marked at several locations by a thin layer of sand-sized biotite mica. Lodgement till was encountered only at scattered localities (in boreholes) at each site. The bedrock surface is of considerable relief, with changes of 200--300 feet over short distances detected. The sequence appears to be the record of a rapidly transgressing sea which inundated a valley where outwash had been deposited by meltwater ahead of retreating ice. As the sea retreated, up to 70 feet of sediment was deposited in a continuous, coarsening-upwards sequence. Subsequent to the marine regression, the sediments were reworked in a subaerial (braided stream) environment. The Surficial Geologic Map of Maine shows that the inland limit of late-glacial marine submergence is located approximately 8 miles southwest of Waterboro, in Alfred, Maine. The marine limit in Alfred takes the form of a NNE trending, blunt-ended embayment. The results of this study suggest that the marine embayment once extended northward from Alfred, and is now a buried feature, possibly representing a preglacial valley, which hosted an estuary in late Wisconsonian time.« less

  14. GIS-based estimation of the winter storm damage probability in forests: a case study from Baden-Wuerttemberg (Southwest Germany).

    PubMed

    Schindler, Dirk; Grebhan, Karin; Albrecht, Axel; Schönborn, Jochen; Kohnle, Ulrich

    2012-01-01

    Data on storm damage attributed to the two high-impact winter storms 'Wiebke' (28 February 1990) and 'Lothar' (26 December 1999) were used for GIS-based estimation and mapping (in a 50 × 50 m resolution grid) of the winter storm damage probability (P(DAM)) for the forests of the German federal state of Baden-Wuerttemberg (Southwest Germany). The P(DAM)-calculation was based on weights of evidence (WofE) methodology. A combination of information on forest type, geology, soil type, soil moisture regime, and topographic exposure, as well as maximum gust wind speed field was used to compute P(DAM) across the entire study area. Given the condition that maximum gust wind speed during the two storm events exceeded 35 m s(-1), the highest P(DAM) values computed were primarily where coniferous forest grows in severely exposed areas on temporarily moist soils on bunter sandstone formations. Such areas are found mainly in the mountainous ranges of the northern Black Forest, the eastern Forest of Odes, in the Virngrund area, and in the southwestern Alpine Foothills.

  15. [Orthopedics and patients under national socialism dictatorship].

    PubMed

    Thomann, K D; Rauschmann, M

    2001-10-01

    The 12-year dictatorship of National Socialism represents a decisive event in the history of orthopedics in Germany. Treatment and care was limited to those patients whose prognosis promised their reintegration into the work force. Those orthopedic patients with mental and psychological handicaps no longer came under the care of orthopedists and were potential candidates for annihilation. Despite concerted efforts to the contrary, as can be gleaned from the lists of topics at the annual meetings, the prevailing political circumstances encumbered scientific activities. The almost total isolation from international contacts had a negative effect. Orthopedists were hindered in their work by the law on sterilization, which provided for sterilization in cases of severe physical deformity. Some orthopedists even considered the presence of hip dysplasia to be an indication. The roles played by Georg Hohmann, Hellmut Eckhardt, Lothar Kreuz, and other leading orthopedists are described in detail. It can be regarded as certain that Hohmann and Eckhardt were able to prevent dire consequences for their orthopedic patients and the profession by cautious tactics. The ethnical problems of involvement with National Socialism are thoroughly discussed.

  18. The notion of "double consciousness" in Alfred Binet's psychological experimentalism.

    PubMed

    Foschi, Renato; Cicciola, Elisabetta

    2006-01-01

    Between 1889 and 1892, Binet published two remarkable essays, On Double Consciousness and Les alterations de la personnalité, which marked the end of a period of researches and interests closely linked to the doctrines on hypnosis and hysteria elaborated by the Ecole de la Salpêtrière. Later on, Binet was to abandon the utilization of hypnosis as a technique of experimentation, after he realized that the suggestibility of the "subjects" of these experiences had led to major experimental mistakes. However, during the years of his work at the Salpêtrière, he elaborated the notion of "double consciousness," which can be considered an alternative both to Ribot's idea of dissociation and to Janet's idea of disaggregation. The notion of double consciousness reveals both the originality of Binet's psychology--which was elaborated at the end of the nineteenth century--and its verifiable link to twentieth-century psychology. Unlike Janet, in fact, Binet did not support a theory of psychological deficiency or "misery," or of the retraction of the sphere of consciousness, which a normal capacity for psychological synthesis would oppose. On the contrary, Binet's psychology resulted in a theory stating that the duality of consciousness works in a perfect and autonomous way within the individual and, thanks to hypnosis, can be investigated in a laboratory.

    In his classic book, "The Problem Child," Alfred Adler (1930) noted that if educators do not understand the "private logic" and goals of a young person, their interventions may do more harm than good.

    Traditional accounts of the Individual Psychology of Alfred Adler tend to sentimentalize his system and obscure its functional flavor. Six basic Adlerian positions on human behavior, including Rudolf Dreikurs' "four goals of misbehavior," are interpreted as a primitive statement of operant principles. Applied techniques long used by Individual Psychology practitioners strongly resemble interventions that applied behavior analysts have developed by more systematic means.

    NASA Astrophysics Data System (ADS)

    Burt, M. A.; Randall, D. A.

    2016-12-01

    Recent comparisons of observations and climate model simulations by I. Tan and colleagues have suggested that the Wegener-Bergeron-Findeisen (WBF) process tends to be too active in climate models, making too much cloud ice, and resulting in an exaggerated negative cloud-phase feedback on climate change. We explore the WBF process and its effect on shortwave cloud forcing in present-day and future climate simulations with the Community Earth System Model, and its super-parameterized counterpart. Results show that SP-CESM has much less cloud ice and a weaker cloud-phase feedback than CESM.

    As part of the expedition GANOVEX VI 1990/91, the Bundesanstalt für Geowissenschaften und Rohstoffe (BGR), the Alfred Wegener Institute for Polar and Marine Research (AWI), and the United States Geological Survey (USGS) carried out an airborne magnetic survey over the northwestern Ross Ice Shelf and McMurdo Sound between Ross Island, the Transantarctic Mountains, and Minna Bluff.The area planned for the aeromagnetic survey connects directly with the GANOVEX IV survey area (BGR & USGS 1987, BACHEM et al. 1989a) which terminated along an approximately cast-west line at about the latitude of Cape Bird. The GANOVEX IV survey covered the Victoria Land Basin - which is the westernmost of the three north/south striking basins in the Ross Sea - from its northern end in the Terra Nova Bay region to its known southern end at Ross Island. A possible southem extension of the Victoria Land Basin and its central graben structure (the Terror Rift as found from seismic surveys (COOPER et al. 1987) and what has been referred to as Victoria Graben in the aeromagnetic interpretation of the GANOVEX IV data (BOSUM et al. 1989) was one of the major targets for this survey.The survey was laid out in the form of blocks. A 135 km wide transect from the Transantarctic Mountains to about 175° W formed the focal block of the survey (Fig. 1) in which all major scientific objectives could be covered. Other survey blocks were planned to the south of this. During the course of the survey it turned out that in the time available no further area could be covered. Indeed, the unfavourable weather conditions made it impossible to complete even the above described main section fully.In detail, the lay-out of the survey area was closely following that of the GANOVEX IV survey to assure compatibility and direct continuation between the two data sets.The line spacing was chosen again to 4.4 km with a tic-line separation of 22 km. The survey altitude of 2,000 ft (610 m) corresponds to that of the Ross

    Airborne measurements in an Arctic mixed-phase nimbostratus cloud were conducted in Spitsbergen on 21 May 2004 during the international Arctic Study of Tropospheric Aerosol, Clouds and Radiation (ASTAR) campaign. The in situ instrument suite aboard the Alfred Wegener Institute Polar 2 aircraft included a polar nephelometer (PN), a cloud particle imager (CPI), a Nevzorov probe, and a standard PMS 2DC probe to measure the cloud particle single-scattering properties (at a wavelength of 0.8 μm), and the particle morphology and size, as well as the in-cloud partitioning of ice/water content. The main objective of this work is to present a technique based on principal component analysis and light-scattering modeling to link the microphysical properties of cloud particles to their optical characteristics. The technique is applied to the data collected during the 21 May case study where a wide variety of ice crystal shapes and liquid water fractions were observed at temperatures ranging from -1°C to -12°C. CPI measurements highlight the presence of large supercooled water droplets with diameters close to 500 μm. Although the majority of ice particles were found to have irregular shapes, columns and needles were the prevailing regular habits between -3°C and -6°C while stellars and plates were observed at temperatures below -8°C. The implementation of the principal component analysis of the PN scattering phase function measurements revealed representative optical patterns that were consistent with the particle habit classification derived from the CPI. This indicates that the synergy between the CPI and the PN can be exploited to link the microphysical and shape properties of cloud particles to their single-scattering characteristics. Using light-scattering modeling, we have established equivalent microphysical models based on a limited set of free parameters (roughness, mixture of idealized particle habits, and aspect ratio of ice crystals) that reproduce the main

    This study aimed to evaluate a recently developed equipment test method by assessing the safe and accurate functioning of the Abbott Optium FreeStyle H portable blood glucose monitor for use in the Alfred Hospital's hyperbaric chamber. The results of this study indicate that the test method can be used successfully to evaluate instruments and/or devices for use in the hyperbaric environment. The evaluation initially found that this particular glucose monitor contained a lithium battery which can be hazardous when used in the hyperbaric environment. However, upon further inspection it was determined the battery posed minimal risk for fire and explosion due to its small capacity and design application. The results indicate that the Abbott Optium FreeStyle H blood glucose monitor operated normally when used in the hyperbaric chamber. This glucometer was found to perform within the calibration specification requirements for accuracy at all stages of a typical hyperbaric treatment and as such the Abbott Optium FreeStyle H blood glucose monitor was deemed safe for use in the hyperbaric chamber at the Alfred Hospital.

    Subglottic stenosis (SGS) in granulomatosis with polyangiitis (GPA) may result from active disease or from chronic recurrent inflammation. The objective of the study was to describe the clinical features and treatment of patients with subglottic stenosis. We retrospectively reviewed the medical records of all patients with SGS due to GPA diagnosed at Rheumatology deparment between January 2000 and June 2015. We present 4 cases of SGS at our department during a period of 15 years. The interval between the presentation of the GPA and SGS varied between 2 and 144 months. The leading symptoms of SGS were dyspnoea on exertion and stridor. Three patients presented SGS without evidence of systemic activity. Two patients presented SGS grade i and received tracheal dilatation; two recurred and three needed a tracheostomy due to severe airway-limiting stenosis. SGS presents high morbidity. Even though subglottic dilatation provides symptomatic relief, recurrences may present. Severe airway-limiting stenosis often requires tracheostomy.

    We have previously characterized from Lactobacillus casei BL23 three α-l-fucosidases, AlfA, AlfB, and AlfC, which hydrolyze in vitro natural fucosyl-oligosaccharides. In this work, we have shown that L. casei is able to grow in the presence of fucosyl-α-1,3-N-acetylglucosamine (Fuc-α-1,3-GlcNAc) as a carbon source. Interestingly, L. casei excretes the l-fucose moiety during growth on Fuc-α-1,3-GlcNAc, indicating that only the N-acetylglucosamine moiety is being metabolized. Analysis of the genomic sequence of L. casei BL23 shows that downstream from alfB, which encodes the α-l-fucosidase AlfB, a gene, alfR, that encodes a transcriptional regulator is present. Divergently from alfB, three genes, alfEFG, that encode proteins with homology to the enzyme IIAB (EIIAB), EIIC, and EIID components of a mannose-class phosphoenolpyruvate:sugar phosphotransferase system (PTS) are present. Inactivation of either alfB or alfF abolishes the growth of L. casei on Fuc-α-1,3-GlcNAc. This proves that AlfB is involved in Fuc-α-1,3-GlcNAc metabolism and that the transporter encoded by alfEFG participates in the uptake of this disaccharide. A mutation in the PTS general component enzyme I does not eliminate the utilization of Fuc-α-1,3-GlcNAc, suggesting that the transport via the PTS encoded by alfEFG is not coupled to phosphorylation of the disaccharide. Transcriptional analysis with alfR and ccpA mutants shows that the two gene clusters alfBR and alfEFG are regulated by substrate-specific induction mediated by the inactivation of the transcriptional repressor AlfR and by carbon catabolite repression mediated by the catabolite control protein A (CcpA). This work reports for the first time the characterization of the physiological role of an α-l-fucosidase in lactic acid bacteria and the utilization of Fuc-α-1,3-GlcNAc as a carbon source for bacteria.

    The interaction-induced absorption by collisional pairs of H2 molecules is an important opacity source in the atmospheres of the outer planets and cool stars ^[1]. The emission spectra of cool white dwarf stars differ significantly in the infrared from the expected blackbody spectra of their cores, which is largely due to absorption by collisional H2--H2, H2--He, and H2--H complexes in the stellar atmospheres. Using quantum-chemical methods we compute the atmospheric absorption from hundreds to thousands of kelvin ^[2]. Laboratory measurements of interaction-induced absorption spectra by H2 pairs exist only at room temperature and below. We show that our results reproduce these measurements closely ^[2], so that our computational data permit reliable modeling of stellar atmosphere opacities even for the higher temperatures ^[2].

    This is a photo of the Apollo 15 Lunar Module, Falcon, on the lunar surface. Apollo 15 launched from Kennedy Space Center (KSC) on July 26, 1971 via a Saturn V launch vehicle. Aboard was a crew of three astronauts including David R. Scott, Mission Commander; James B. Irwin, Lunar Module Pilot; and Alfred M. Worden, Command Module Pilot. The first mission designed to explore the Moon over longer periods, greater ranges and with more instruments for the collection of scientific data than on previous missions, the mission included the introduction of a $40,000,000 lunar roving vehicle (LRV) that reached a top speed of 16 kph (10 mph) across the Moon's surface. The successful Apollo 15 lunar landing mission was the first in a series of three advanced missions planned for the Apollo program. The primary scientific objectives were to observe the lunar surface, survey and sample material and surface features in a preselected area of the Hadley-Apennine region, setup and activation of surface experiments and conduct in-flight experiments and photographic tasks from lunar orbit. Apollo 15 televised the first lunar liftoff and recorded a walk in deep space by Alfred Worden. Both the Saturn V rocket and the LRV were developed at the Marshall Space Flight Center.

    Recent debates on the mailing date of Alfred Russel Wallace's 'Ternate essay' to Charles Darwin in the spring of 1858 have ignored certain details that, once taken into account, alter the matter considerably. Here, a closer look is taken at the critical question of whether Wallace's manuscript-accompanying letter represented a reply to the Darwin letter that arrived in Ternate on 9 March; it is concluded that it very probably did not.

    Recently drilled deep ice cores from Central Greenland (GRIP and GISP2) provide the most detailed results available on climatic variation in the northern hemisphere during the last 100,000 years, a period that includes the Holocene (0-11.5 ka) and most of the Wisconsin glacial period. Summer-winter variation in various physical and chemical properties of polar ice allows dating of ice cores by annual layer counting. Several such methods are currently being employed on an ice core drilled by the new North Greenland Ice Core Project (NGRIP), which is aimed at extending the Greenland ice palaeoclimatic record through the last interglacial, the Eemian. Two examples will be presented: (1) visual and photographic studies of seasonal variation in stratigraphic layering, crystal size, air bubble and clathrate concentration, and (2) studies of electric stratigraphy, using the method of dielectric profiling (DEP). This method records the AC conductivity of ice cores, which is negatively correlated with the concentration of airborne dust in the ice but positively correlated with volcanic and marine aerosols. Comprehensive surface traverse programs, which include shallow coring and ice velocity measurements, have recently been carried out by the Alfred Wegener Institute in previously little-investigated regions of Greenland and Antarctica. Serving partly as reconnaissance prior to deep drilling projects, such studies also help to reduce considerable uncertainties in the mass balance of the two large polar ice sheets and thus in their estimated response to climate change. Main results of a recent traverse in North Greenland include the following: (1) A new map of the accumulation distribution on the ice sheet indicates a large low-accumulation region in Northeast-Greenland; (2) North Greenland records show significantly greater climatic variability during the last 500 yr than corresponding records from the southern part of the ice sheet; and (3) data on variation in

CAM3 significantly underestimates the observed boundary layer mixed-phase cloud fraction and cannot realistically simulate the variations of liquid water fraction with temperature and cloud height due to its oversimplified cloud microphysical scheme.

Sensitivity tests show that these results are not sensitive to the analysis data used for model initialization. Increasing model horizontal resolution helps capture the subgrid-scale features in Arctic frontal clouds but does not help improve the simulation of the single-layer boundary layer clouds.

    The degree of glaciation of mixed-phase clouds constitutes one of the largest uncertainties in climate prediction. In order to better understand cloud glaciation, cloud spectrometer observations are presented in this paper, which were made in the mixed-phase temperature regime between 0 and -38 °C (273 to 235 K), where cloud particles can either be frozen or liquid. The extensive data set covers four airborne field campaigns providing a total of 139 000 1 Hz data points (38.6 h within clouds) over Arctic, midlatitude and tropical regions. We develop algorithms, combining the information on number concentration, size and asphericity of the observed cloud particles to classify four cloud types: liquid clouds, clouds in which liquid droplets and ice crystals coexist, fully glaciated clouds after the Wegener-Bergeron-Findeisen process and clouds where secondary ice formation occurred. We quantify the occurrence of these cloud groups depending on the geographical region and temperature and find that liquid clouds dominate our measurements during the Arctic spring, while clouds dominated by the Wegener-Bergeron-Findeisen process are most common in midlatitude spring. The coexistence of liquid water and ice crystals is found over the whole mixed-phase temperature range in tropical convective towers in the dry season. Secondary ice is found at midlatitudes at -5 to -10 °C (268 to 263 K) and at higher altitudes, i.e. lower temperatures in the tropics. The distribution of the cloud types with decreasing temperature is shown to be consistent with the theory of evolution of mixed-phase clouds. With this study, we aim to contribute to a large statistical database on cloud types in the mixed-phase temperature regime.

    The use of eponyms in scientific terminology and particularly in medical terminology has a long tradition but discussion often arises especially since the involvement of the protagonists in the National Socialist regime which led to strong controversies (e. g. Clara, Stieve, Reiter, Wegener). They are a component of cultural specialist memories and contribute to the conciseness of the nomenclature. For the specialization of urology a total list of eponyms in general use or an analysis of the use of eponyms does not exist. The eponym Tyson's glands is a good example of the tradition of eponyms in urology and the discussion about the related anatomical facts.

Complicated pronunciations of diagnosis have always placed residents in an intricate state. Each one is trying his best to make this cumbersome subject comparatively more acceptable and convenient. The present paper is an attempt to further simplify the subject by correlating difficult conditions with commonly used and seen things such as fruit and food. A total of 45 dermatological conditions were found to be based on fruit and food eponyms. For example, strawberries can remind us of strawberry gums of Wegener's granulomatosis and strawberry nevus.

    At the beginning of the XXth century, Wegener proposed a theory – that of the roaming drift of the continents – unifying the rival theories of the Europeans and the Americans. As the work of a non-specialist who didn’t trouble himself with specific details, it raised numerous criticisms from specialists in various disciplines though others welcomed and supported it. Some even understood that despite its flaws, it started a new research program. Paradoxically, as regards its simplicity, nonspecialists – engineers, popularizers, secondary school teachers and even believers in para-sciences – gave it a favorable reception. Being amateurs, they continued to endorse it when specialists abandoned it.

    Structured postgraduate programs are a relatively new feature at German Higher Educational Institutions, mainly fostered in the 90ies by the funding programs of the German Science Foundation (Research Training Groups) and the Max-Planck-Association (International Max Planck Research Schools). Since then, funding opportunities for postgraduate programs have equally been set up by the Helmholtz and Leibniz Associations as well as the Excellence Initiative. Today, doctoral candidates can chose from a wide range of training programs to earn a doctoral degree within a structured framework under excellent research conditions. In consequence, the percentage of PhD students in natural sciences that follow a PhD within a structured program has been continuously increasing. Graduate Schools provide a roof under which different curricula can be accommodated. They offer a comprehensive training program, foster interdisciplinary thinking and are a key instrument for quality assurance by providing rules relevant and equal to all doctoral candidates regardless of funding or affiliation. With more and more Graduate Schools becoming a permanent feature in the training of doctoral candidates, universities and research institutions are provided with a tool to create added value for the whole range of early career scientists and beyond. The Alfred Wegener Institute for Polar and Marine Research (AWI) is currently developing a comprehensive strategy for early and pre-career support with the aim to provide a continuous support chain from high school students to Postdocs. Included are also the apprentices that get a vocational training at AWI as laboratory assistants, office clerks or qualified IT specialists. AWI aims at establishing a solid training network between these groups (apprentices, high school students, Bc and Ms students, internships, doctoral candidates, and Postdocs) across biographic borders. This network serves more than the classical transition phases from high school

    the Alfred Wegener Institute for Polar and Marine Research and the University of Hamburg, Germany. One of the responsibilities of TEPO is to provide assistance to students taking part in scientific research (undergraduate and post-graduate practical work and organization of summer schools and seminars). In 2005 a joint summer student field excursion with the Moscow State University Department of Cryolithology and Glaciology took place at TEPO headquarters. The teaching courses consist of the following main topics: 1. Environment and Permafrost of northern West Siberia; 2. Paleocryogenic Formation of Alluvial Terraces; 3. Hydrology and Hydrogeological Conditions of the Territory; 4. Geotechnical Monitoring of Gas Fields; 5. Geotechnical Dangers in the Cryolithozone. The workshop "Stability of Pipelines in the Cryolithozone" held in Nadym at August, 29-31 with participation of "Nadymgasprom", TSOGU and Hokkaido University, Graduate School of Engineering (Japan) included a field excursion. TEPO is expected to be the basis for scientific and educational exchange with national and foreign universities and research institutes and part of the global international monitoring in the northern regions.

    The northern Baffin Bay is a key area for testing plate kinematic models for the Paleocene-Eocene motion of Greenland relative to North America and to decipher the evolution of the thick sedimentary basins in this area. In summer 2010, a multidisciplinary marine geoscientific expedition focusing on the Greenland part of northern Baffin Bay was performed under the direction of the Federal Institute for Geosciences and Natural Resources Hannover, Germany in cooperation with the Alfred-Wegener Institute Bremerhaven. Using 70 days ship time onboard the German R/V Polarstern a comprehensive data set was acquired along profiles extending from the deep oceanic basin in the central part of North Baffin Bay onto the Greenland continental margin in an area which was bordered by the Kane Basin in the North and Disco Island in the South. By means of multi-channel seismic, wide angle seismic, gravimetric and magnetic methods the structural inventory of the crust in the NW Baffin Bay was investigated. Additionally, heat flow data and sediment cores were collected at selected positions along lines across the Greenland continental margin. The cores were extracted for geochemical and geomicrobiological analysis to be used for basin modeling and studying the hydrocarbon potential. Aeromagnetic data was acquired covering part of the marine survey area to investigate magnetic signatures of the oceanic crust and the continental margin. In our presentation we will give an overview of the first results of the expedition with special focus on multi-channel seismic data. With a total length of 3500 km, the initial interpretation of multi-channel seismic data shows that the West Greenland margin is a typical passive continental margin with large rotated basement blocks, listric faults facing mainly seaward, and deep syn-rift-basins in between. The most prominent reflector under the shelf and the slope probably indicates the transition from rifting to drifting and therefore the beginning of

    JOICFP President Shidzue Kato was influenced by and friends with Margaret Sanger from their initial meeting in 1920 to Sanger's death in 1966. Bruce Alfred is currently directing and producing a 90-minute documentary film about Sanger and her pioneering work in promoting the development and use of family planning. Once completed in the Spring of 1997, the film will be broadcast nationally in the US on Public Television. It is being produced with support from the National Endowment for the Humanities and several private foundations. Alfred interviewed Kato for three hours to gain insight into the life and legacy of Margaret Sanger. Sanger inspired Kato to make birth control her life's work. Kato spoke about how the prewar, pronatalist Japanese government allowed Sanger to visit Japan in 1922 only on the condition that she not speak about birth control. This official opposition and the subsequent reaction, however, actually fueled interest in Sanger and her message, and caused her ideas to become widely known among the Japanese public. While in Japan, Sanger did manage to discuss family planning, but in English in a closed meeting. Oddly enough, the government honored Sanger after the second World War with the highest award presented to non-Japanese. Kato noted how unfortunate it was that Sanger died in 1966 without witnessing the realization of the UNFPA.

    The world consists of inter-connected processes. It is an illusion to think that things exist. As argued by Alfred North Whitehead processes are ontologically fundamental. Since the building blocks do not consist of things with specific intrinsic properties, we can hope that a general science of the processes underlying and controlling the behavior of apparently very different situations, such as the evolution of an ecosystem or the performance of a piece of music by a band, may very well exist...
