Marginality and Variability in Esperanto.

Science.gov (United States)

Brent, Edmund

This paper discusses Esperanto as a planned language and refutes three myths connected to it, namely, that Esperanto is achronical, atopical, and apragmatic. The focus here is on a synchronic analysis. Synchronic variability is studied with reference to the structuralist determination of "marginality" and the dynamic linguistic…

Introduction: In Search of Esperanto

Directory of Open Access Journals (Sweden)

Humphrey Tonkin

2015-04-01

Full Text Available After almost one hundred years of continuous use, Esperanto has achieved the status and character of a fully-fledged language, functioning much as any other language does. Research on Esperanto is hampered because knowledge of the subject is often regarded, ipso facto, as evidence of a lack of objectivity, and also because Esperanto, as largely an L2, is elusive, and its speakers hard to quantify. The problem is compounded by the rapid shift in its community from membership-based organizations to decentralized, informal web-based communication. Also shifting are the community’s ideological underpinnings: it began as a response to lack of communication across languages but is now often perceived by its users as an alternative, more equitable means of communication than the increasingly ubiquitous English. Underlying these changes is a flourishing cultural base, including an extensive literature and periodical press. There is a need for more research – linguistic, sociolinguistic, and in the history of ideas. In intellectual history, Esperanto and related ideas have played a larger role than is generally recognized, intersecting with, and influencing, such movements as modernization in Japan, the development of international organizations, socialism in many parts of the world, and, in our own day, machine translation.

The Decline and Fall of Esperanto

Science.gov (United States)

Patterson, Robert; Huff, Stanley M.

1999-01-01

In 1887, Polish physician Ludovic Zamenhof introduced Esperanto, a simple, easy-to-learn planned language. His goal was to erase communication barriers between ethnic groups by providing them with a politically neutral, culturally free standard language. His ideas received both praise and condemnation from the leaders of his time. Interest in Esperanto peaked in the 1970s but has since faded somewhat. Despite the logical concept and intellectual appeal of a standard language, Esperanto has not evolved into a dominant worldwide language. Instead, English, with all its idiosyncrasies, is closest to an international lingua franca. Like Zamenhof, standards committees in medical informatics have recognized communication chaos and have tried to establish working models, with mixed results. In some cases, previously shunned proprietary systems have become the standard. A proposed standard, no matter how simple, logical, and well designed, may have difficulty displacing an imperfect but functional “real life” system. PMID:10579602

Exchange studies in the Kiel Bight

Energy Technology Data Exchange (ETDEWEB)

Hubrich, L M; Schott, F

1975-11-01

The knowledge of exchange and mixing parameters and their dependence on meteorological and oceanographic factors in coastal waters plays a predominant role in the estimation of the capacity of those areas for waste water and waste heat. On this subject experimental investigations are carried out in the Kiel Bight, part of the Western Baltic. The paper reports about dye mixing experiments, about the development of a combined aircraft-ship measuring method and about experimental results with low wind velocities and low current velocities. On the basis of measured horizontal surface temperature distributions an estimation of the local heat load in the inner Kiel Fjord from the cooling water of a power plant is also given.

An Algorithm for Morphological Segmentation of Esperanto Words

Directory of Open Access Journals (Sweden)

Guinard Theresa

2016-04-01

Full Text Available Morphological analysis (finding the component morphemes of a word and tagging morphemes with part-of-speech information is a useful preprocessing step in many natural language processing applications, especially for synthetic languages. Compound words from the constructed language Esperanto are formed by straightforward agglutination, but for many words, there is more than one possible sequence of component morphemes. However, one segmentation is usually more semantically probable than the others. This paper presents a modified n-gram Markov model that finds the most probable segmentation of any Esperanto word, where the model’s states represent morpheme part-of-speech and semantic classes. The overall segmentation accuracy was over 98% for a set of presegmented dictionary words.

The Teaching and Learning of Esperanto

Directory of Open Access Journals (Sweden)

Duncan Charters

2015-04-01

Full Text Available One of the first tasks faced by Zamenhof, the inventor of Esperanto (1887, was establishing its status as a living language, achieved in part by teaching the language to others, in part by translation and literary creation, and in part by forming a community of users. One of the earliest learners, Leo Tolstoy, emphasized its ease of learning, and both the early history of the language and contemporary experience show that the receptive and productive skills entailed in learning the language are unusually mutually reinforcing. In formal language-learning situations, students are able to reach an acceptable level of proficiency relatively quickly, allowing them to put the language to practical use. They are also able to learn on their own. Ease of learning builds confidence, so that Esperanto constitutes a good introduction to language study in general, even though the language is more complex linguistically than it may appear at first sight. The language also helps the learning of cultural sensitivity. In recent years, electronic aids to teaching and learning have proliferated and there are many resources available to the teacher and learner.

Integrated School of Ocean Sciences: Doctoral Education in Marine Sciences in Kiel

Science.gov (United States)

Bergmann, Nina; Basse, Wiebke; Prigge, Enno; Schelten, Christiane; Antia, Avan

2016-04-01

Marine research is a dynamic thematic focus in Kiel, Germany, uniting natural scientists, economists, lawyers, philosophers, artists and computing and medical scientists in frontier research on the scientific, economic and legal aspects of the seas. The contributing institutions are Kiel University, GEOMAR Helmholtz Centre for Ocean Research Kiel, Kiel Institute for the World Economy and Muthesius University in Kiel. Marine science education in Kiel trains young scientists to investigate the role of the oceans in global change, risks arising from ocean usage and sustainable management of living and non-living marine resources. Basic fundamental research is supplemented with applied science in an international framework including partners from industry and public life. The Integrated School of Ocean Sciences (ISOS) established through the Cluster of Excellence "The Future Ocean", funded within the German Excellence Initiative, provides PhD candidates in marine sciences with interdisciplinary education outside of curricular courses. It supports the doctoral candidates through supplementary training, a framework of supervision, mentoring and mobility, the advisors through transparency and support of doctoral training in their research proposals and the contributing institutions by ensuring quality, innovation and excellence in marine doctoral education. All PhD candidates financed by the Helmholtz Research School for Ocean System Science and Technology (HOSST) and the Collaborative Research Centre 754 "Climate-biogeochemical interactions in the tropical ocean" (SFB 754) are enrolled at the ISOS and are integrated into the larger peer community. Over 150 PhD candidate members from 6 faculties form a large interdisciplinary network. At the ISOS, they sharpen their scientific profile, are challenged to think beyond their discipline and equip themselves for life after a PhD through early exposure to topics beyond research (e.g. social responsibility, public communication

Wincewicz, Andrzej; Sulkowska, Mariola; Musiatowicz, Marcin; Sulkowski, Stanislaw

2009-06-01

To reconstruct the biography of the Polish otorhinolaryngologist Leon Zamenhof (1875-1934), a brother of Ludwik Zamenhof, who is famous for invention of the international language Esperanto. Biographical information was collected from pre-World War II resources. Zamenhof developed several important new forms of treatment to help the hearing impaired. Zamenhof was especially interested in the education of deaf children and the therapy necessary to facilitate their integration into society. His significant achievements were a phonetic method of therapy for the hearing impaired and an automatic device for ear insufflation that was considered indispensable in the management of pyorrhea. In addition, Zamenhof initiated various forms of social support among physicians within the medical community of Warsaw, Poland; made health care available to children with hearing impairments; and organized a Jewish school for deaf children. Zamenhof tried to change public attitudes toward deafness, working to promote the integration of the deaf into wider society. He also translated Polish literature into Esperanto. With similar aims to his brother Ludwik, Leon Zamenhof strived to enhance and broaden communication among people who could not hear and to persuade people to change their attitudes about deafness.

Equal Opportunities for Women in Marine Sciences in Kiel: Activities and Measures

Science.gov (United States)

Kamm, Ruth

2016-04-01

Women are still largely underrepresented in geosciences in general. Particularly at the level of professorships and permanent research staff positions this also applies to marine science institutions in Kiel, i.e. the research focus Kiel Marine Sciences at Kiel University and the GEOMAR Helmholtz Centre for Ocean Research Kiel. Both institutions are closely collaborating, for instance in the frame of two major third-party funded collaborative projects: The Cluster of Excellence 'The Future Ocean', funded within the German Excellence Initiative, and the Collaborative Research Centre 'Climate - Biogeochemistry Interactions in the Tropical Ocean' (SFB 754) financed through the German Research Foundation (DFG). Both funding schemes request for measures to increase the participation of female scientists in leading positions. As an innovative approach, The Future Ocean and SFB 754 jointly finance the position of a coordinator for gender measures who is based at the university's Central Office for Gender Equality, Diversity & Family since 2012. This allows for the coordinated development and implementation of programmes to support female marine scientists, with a focus on the postdoctoral phase, and to offer a broader spectrum of activities to raise awareness of gender imbalance in the research community. The aim of this presentation is to give insight into activities and achievements, among them the mentoring programme via:mento_ocean for female postdocs in marine sciences. The programme via:mento_ocean has been acknowledged as a best practice instrument to support women scientists in a close disciplinary but international setting and was incorporated into the DFG's online toolbox of gender equality measures.

War of ontology worlds: mathematics, computer code, or Esperanto?

Science.gov (United States)

Rzhetsky, Andrey; Evans, James A

2011-09-01

The use of structured knowledge representations-ontologies and terminologies-has become standard in biomedicine. Definitions of ontologies vary widely, as do the values and philosophies that underlie them. In seeking to make these views explicit, we conducted and summarized interviews with a dozen leading ontologists. Their views clustered into three broad perspectives that we summarize as mathematics, computer code, and Esperanto. Ontology as mathematics puts the ultimate premium on rigor and logic, symmetry and consistency of representation across scientific subfields, and the inclusion of only established, non-contradictory knowledge. Ontology as computer code focuses on utility and cultivates diversity, fitting ontologies to their purpose. Like computer languages C++, Prolog, and HTML, the code perspective holds that diverse applications warrant custom designed ontologies. Ontology as Esperanto focuses on facilitating cross-disciplinary communication, knowledge cross-referencing, and computation across datasets from diverse communities. We show how these views align with classical divides in science and suggest how a synthesis of their concerns could strengthen the next generation of biomedical ontologies.

Results of fractal analysis of the Kiel extensive air shower data

International Nuclear Information System (INIS)

Kempa, J.; Samorski, M.

1998-01-01

For years there has been a problem in cosmic ray studies of how to distinguish individual extensive air showers (EAS) originating from primary protons, heavy nuclei or primary photons. In this paper results of experimental data obtained from the fractal analysis of particle density distributions in individual EAS detected in the range of shower sizes N e between 1.4x10 5 -5x10 6 by the old Kiel experiment are presented. The Lipschitz-Hoelder exponent distributions of EAS detected by the Kiel experiment are discussed. The examples of EAS most probably originating from primary protons, heavy nuclei and high-energy gamma-rays are presented. The lateral distributions of charged particle densities at small distances, angular and size spectra and the mass composition of primary cosmic ray particles around the 'knee' of the energy spectrum are discussed. The Monte Carlo simulation data illustrating the problem of interest are also shown. (author)

Regional flood impact assessment for Kiel and Eckernförde, Germany

Science.gov (United States)

Shustikova, Iuliia; Viavattene, Christophe; Seiß, Guntram

2017-04-01

It is well-observed that extreme flood events bring considerable destruction to coastal communities. The estimates of damage increases when direct and indirect losses are both considered in the assessment. This study applied the INtegrated DisRuption Assessment (INDRA) model which is designed to estimate and compare not only tangible but also intangible losses such as risk to life, recovery mechanisms and household displacement. Multi-criteria analysis (MCA) was performed in order to compare hotspots of high flood risk on the regional scale and detect which impact indicators influence results the most. INDRA allowed assessing the following impact indicators: direct damages to buildings and roads, transport disruption, risk to life and financial recovery mechanisms of private households and businesses. The focus was on two hotspots of flood risk, where direct and indirect impacts from 200 years flood were assessed and analyzed in terms of relative importance to the region. The region here was defined as municipalities located on the Baltic Sea coast within the Schleswig-Holstein state, Germany. The hotspots are the towns of Kiel and Eckernförde. They are urban areas with a high concentration of people and assets, which previously experienced extreme flood events. From the performed investigation it was found out that modeled flood differently impacts Kiel and Eckernförde. The results produced by MCA show that the scores of direct and indirect damage are slightly higher in Eckernförde than in Kiel. Transport disruption is a compelling element in the performed regional impact assessment and demonstrated immense weight. Extreme events may pose significant direct and indirect impacts on the coastal roads, obstructing not only the access to important landmarks such as hospitals, train stations, harbors, etc. but also to contiguous municipalities. Yet, the analysis showed that other impact indicators are rather of local importance and would not cause vast damage on a

Punctuation effects in english and esperanto texts

Science.gov (United States)

Ausloos, M.

2010-07-01

A statistical physics study of punctuation effects on sentence lengths is presented for written texts: Alice in wonderland and Through a looking glass. The translation of the first text into esperanto is also considered as a test for the role of punctuation in defining a style, and for contrasting natural and artificial, but written, languages. Several log-log plots of the sentence-length-rank relationship are presented for the major punctuation marks. Different power laws are observed with characteristic exponents. The exponent can take a value much less than unity ( ca. 0.50 or 0.30) depending on how a sentence is defined. The texts are also mapped into time series based on the word frequencies. The quantitative differences between the original and translated texts are very minutes, at the exponent level. It is argued that sentences seem to be more reliable than word distributions in discussing an author style.

Equilibrium and dynamic methods when comparing an English text and its Esperanto translation

Ausloos, M.

2008-11-01

A comparison of two English texts written by Lewis Carroll, one (Alice in Wonderland), also translated into Esperanto, the other (Through the Looking Glass) are discussed in order to observe whether natural and artificial languages significantly differ from each other. One dimensional time series like signals are constructed using only word frequencies (FTS) or word lengths (LTS). The data is studied through (i) a Zipf method for sorting out correlations in the FTS and (ii) a Grassberger-Procaccia (GP) technique based method for finding correlations in LTS. The methods correspond to an equilibrium and a dynamic approach respectively to human texts features. There are quantitative statistical differences between the original English text and its Esperanto translation, but the qualitative differences are very minutes. However different power laws are observed with characteristic exponents for the ranking properties, and the phase space attractor dimensionality. The Zipf exponent can take values much less than unity (∼0.50 or 0.30) depending on how a sentence is defined. This variety in exponents can be conjectured to be an intrinsic measure of the book style or purpose, rather than the language or author vocabulary richness, since a similar exponent is obtained whatever the text. Moreover the attractor dimension r is a simple function of the so called phase space dimension n, i.e., r=nλ, with λ=0.79. Such an exponent could also be conjectured to be a measure of the author style versatility, - here well preserved in the translation.

By means of heat and power generation, the municipal power station Kiel at the east bank of the Kieler Foerde has the possibility of uncoupling a thermal performance of up to 295 MW into the district heating grid of public utilities Kiel. The necessary conversion of the fuel required an increase of the performance of the mill in order to be able to grind the larger fuel flow during continuous boiler performance. For this, in the first step the exchange of the wing separators against lamella separators was selected. The authors of the contribution under consideration report on an adjustment of the crushing mills at changing fuel qualities.

X-31 Kiel Probe Side View

A photograph of the noseboom on the X-31 shows the Kiel air data probe angled at 10 degrees to better align the tip with the airflow at very high angles of attack. The devices were mounted on the nose of the X-31s to measure air pressure. Icing in the unheated Kiel probe on the first X-31 (Bu. No. 164584), caused that aircraft to crash on January 19, 1995. The aircraft obtained data that may apply to the design and development of highly-maneuverable aircraft of the future. Each had a three-axis thrust-vectoring system, coupled with advanced flight controls, to allow it to maneuver tightly at very high angles of attack. The X-31 Enhanced Fighter Maneuverability (EFM) demonstrator flew at the Ames- Dryden Flight Research Facility, Edwards, California (redesignated the Dryden Flight Research Center in 1994) from February 1992 until 1995 and before that at the Air Force's Plant 42 in Palmdale, California. The goal of the project was to provide design information for the next generation of highly maneuverable fighter aircraft. This program demonstrated the value of using thrust vectoring (directing engine exhaust flow) coupled with an advanced flight control system to provide controlled flight to very high angles of attack. The result was a significant advantage over most conventional fighters in close-in combat situations. The X-31 flight program focused on agile flight within the post-stall regime, producing technical data to give aircraft designers a better understanding of aerodynamics, effectiveness of flight controls and thrust vectoring, and airflow phenomena at high angles of attack. Stall is a condition of an airplane or an airfoil in which lift decreases and drag increases due to the separation of airflow. Thrust vectoring compensates for the loss of control through normal aerodynamic surfaces that occurs during a stall. Post-stall refers to flying beyond the normal stall angle of attack, which in the X-31 was at a 30-degree angle of attack. During Dryden

Radical prostatectomy (RP) is the most common definitive invasive treatment option for localized prostate cancer. Although the different surgical procedures-open RP, laparoscopic RP, and robot-assisted laparoscopic RP-do not differ significantly for the results of postoperative erectile dysfunction (ED) and continence, the fear of losing erectile function (EF) is often an important factor for preoperatively sexually active men when deciding for or against a procedure. To review the available literature on rehabilitation of EF after RP and to evaluate the value of the "Kiel concept" against different strategies of phosphodiesterase type 5 inhibitor (PDE5i) low-dose treatments. A review of the available literature up to January 2017 was undertaken using the key terms postsurgical ED, penile rehabilitation," PDE5i rehabilitation, and PDE5i daily dose treatment. As a main outcome measure we chose reviewed different concepts on the rehabilitation of EF after RP, taking into account the clinical background of the Kiel concept. The different therapeutic concepts for rehabilitation of EF after nerve-sparing RP are surprising. The most frequently applied method is application of different PDE5is. Despite different studies on efficacy, the issue of an optimal concept remains unresolved. The reason for this, among others, can be found in the difficulty of comparing different studies, which can vary with respect to the degree of nerve sparing, postoperative preservation of nocturnal erections, concomitant morbidity, and the number and experience of surgeons. In 86% of patients, the Kiel concept has been shown to support rehabilitation of EF after nerve-sparing RP with some form of therapeutic method. The Kiel concept is one therapeutic option among other comparable therapeutic options. Osmonov DK, Jünemann KP, Bannowsky A.

The internal and external North Atlantic Sector variability is investigated by means of a multimillennial control run and forced experiments with the Kiel Climate Model (KCM). The internal variability is studied by analyzing the control run. The externally forced variability is investigated in a run with periodic millennial solar forcing and in greenhouse warming experiments with enhanced carbon dioxide concentrations. The surface air temperature (SAT) averaged over the Northern Hemisphere simulated in the control run displays enhanced variability relative to the red background at decadal, centennial, and millennial timescales. Special emphasis is given to the variability of the Meridional Overturning Circulation (MOC). The MOC plays an important role in the generation of internal climate modes. Furthermore, the MOC provides a strong negative feedback on the Northern Hemisphere SAT in both the solar and greenhouse warming experiments, thereby moderating the direct effects of the external forcing in the North Atlantic. The implications of the results for decadal predictability are discussed. (orig.)

We have investigated the effect of local perturbations of the geomagnetic field on the vertical cosmic ray cutoff rigidities at Jungfraujoch and Kiel as representative mid-latitude neutron monitor stations. The main, effective, and Stoermer vertical cutoff rigidities and their changes were determined by utilizing the trajectory-tracing technique in a magnetic field which is modeled as a simple dipole field to which the disturbance field is superposed. It was found that the cosmic ray cutoff rigidities are most sensitive to variations of the z component of the geomagnetic field at geomagnetic latitudes -20 0 0 and at longitudes within 90 0 to the east of these northern hemisphere stations. Furthermore, cutoff rigidity variations at Kiel are predominantly due to changes of the geomagnetic field within geocentric distances 2.5R/sub E/< r<6R/sub E/, whereas at Jungfraujoch changes in cutoff rigidities are caused almost exclusively by magnetic disturbances within 1R/sub E/< r<4.5R/sub E/. For both locations the dependence of the main, effective, and Stoermer vertical cutoff rigidities on the radial, latitudinal and longitudinal structure of the magnetic perturbations is given explicitly. The results are discussed with respect to the theory by Treiman (1953) describing the effect of a ring current on cosmic ray cutoff rigidities. It is also shown that for the analysis of the characteristic properties of the correlation between cutoff rigidity variations and specific geomagnetic perturbations the rigidity corresponding to the first ''discontinuity band'' of the rigidity spectrum is an extremely useful parameter

To understand determinants of overweight, several studies addressed the association between neighbourhood characteristics and adult obesity. However, little is known about the association of such characteristics with adolescents' overweight. This study aims at the influence of neighbourhood characteristics on adolescent body mass index (BMI) and lifestyle and to what extent BMI and lifestyle variation between neighbourhoods can be explained by neighbourhood characteristics. We used cross-sectional data from the Kiel Obesity Prevention Study collected between 2004 and 2008 in 28 different residential districts of the city of Kiel (North Germany). Anthropometric data were available for 1675 boys and 1765 girls (n=3440) aged 13-15 years, and individual lifestyle factors and sociodemographic data were included in the analysis. At the macro level, six different neighbourhood characteristics were used: unemployment rate, population density, traffic density, prevalence of energy-dense food supply, number of sports fields and parks, and crime rate. To test our main hypothesis, linear and logistic multilevel regression analyses were performed to predict BMI and lifestyle factors in individuals nested in neighbourhoods. Findings of multilevel analysis show little between-neighbourhood variations in BMI and health-related behaviours. In all, 2% of BMI variation, 4% of media time variation and 3% of variation in snacking behaviour could be attributed to differences in neighbourhoods. Environmental factors are significantly associated with adolescent BMI and health-related behaviour; however, their total effect is small. Owing to these results, recommendations for structural policy measures as part of prevention of overweight in adolescents must be made cautiously.

Kiel Canal: Past and future threats for shipping resulting from precipitation, wind surge and sea level rise

The Kiel Canal is the most frequented artificial waterway in the world. It connects the North Sea and the Hamburg Harbor with the Baltic Sea and has a length of about 100 km. The Canal receives its water from the upper catchment of the river Eider. Discharge from the Canal towards the North Sea is via the sluices at Brunsbüttel (90%) into river Elbe and into the Baltic Sea via the sluices at Kiel-Holtenau. A risk of closure of the Canal occurs when high precipitation in the catchment meets high water levels in the river Elbe and/or the Baltic preventing the discharge of excess Canal water. Future sea level rise jointly with other effects such as possibly increasing wind surge and precipitation will close the gap between the inner and outer water levels, so that someday the outside levels will surmount the inner one. The German Federal Ministry of Transport and Digital Infrastructure (BMVI) tasked its internal Network of Experts to run a case study on the evolution of critical water levels in order to estimate risks and vulnerabilities for adaptation measures. First step of the investigation is a search for factors or combination of factors responsible for closures in the past. Candidates are factors such as higher water levels at low tides, high precipitation events on land, soil moisture and human factors like preventive water management measures. Second step will be the search for the natural criteria in climate projections. Here we report on the results of the first step of the case study with a focus on the exit towards the North Sea. There, discharge is possible only during low tide. Presently still sufficient difference in height exists between the levels in the Canal and the river Elbe allowing for a free flow of excess Canal water. Shipping is ceased when levels in the Canal surpass safety limits due to high precipitation events in the catchment jointly with high outer water levels. We used atmospheric data from ERA-Interim reanalysis instead of gauge data

Medical emergencies on large passenger ships without doctors: the Oslo-Kiel-Oslo ferry experience.

The Oslo-Kiel-Oslo route is currently the only direct ferry crossing between Norway and Germany, covered by 2 cruise-and-cars ferries carrying about 2,600 passengers each and sailing every day (20 h at sea, 4 h in port). Unlike most ocean going cruise vessels, they are not required to carry a physician but an on-board paramedic handles medical emergencies. The aim of the study was to provide data on medical emergencies leading to helicopter evacuations (helivacs) or other urgent transfers to facilities ashore from the two ferries during a 3-year period. Data about the ferries, passengers, crew, helivacs and other medical transfers were collected from official company statistics and the paramedics' transfer reports. A total of 169 persons, including 14 (8.3%) crewmembers, were transferred from the ferries to land-based facilities by ambulance while alongside (n = 80; 47.3%) or evacuated by helicopter (n = 85; 50.3%) and rescue boat (n = 4; 2.4%) during the 3-year period. Transfer destinations were Denmark (n = 53), Germany (n = 49), Norway (n = 48) and Sweden (n = 19). The passenger helivac rate was 2.4 per 100,000 passenger-days. One person was airlifted from a ferry every 2 weeks. Among helivacs, 40% were heart-related, and more cardiac cases were airlifted than transferred by ambulance in port. All helivac requests were made after discussion between the ferry's paramedic and telemedical doctors ashore and agreement that the medical challenge exceeded the ferry's capability. This close cooperation kept the threshold for arranging helivacs from the ferries low, enabling short transport times to land-based facilities for critically ill patients. Further studies, including feedback from the receiving hospitals, are needed to determine measures that can reduce possible helicopter overutilisation without compromising patient safety and outcome.

The Kiel data management infrastructure - arising from a generic data model

Fleischer, D.; Mehrtens, H.; Schirnick, C.; Springer, P.

2010-12-01

The Kiel Data Management Infrastructure (KDMI) started from a cooperation of three large-scale projects (SFB574, SFB754 and Cluster of Excellence The Future Ocean) and the Leibniz Institute of Marine Sciences (IFM-GEOMAR). The common strategy for project data management is a single person collecting and transforming data according to the requirements of the targeted data center(s). The intention of the KDMI cooperation is to avoid redundant and potentially incompatible data management efforts for scientists and data managers and to create a single sustainable infrastructure. An increased level of complexity in the conceptual planing arose from the diversity of marine disciplines and approximately 1000 scientists involved. KDMI key features focus on the data provenance which we consider to comprise the entire workflow from field sampling thru labwork to data calculation and evaluation. Managing the data of each individual project participant in this way yields the data management for the entire project and warrants the reusability of (meta)data. Accordingly scientists provide a workflow definition of their data creation procedures resulting in their target variables. The central idea in the development of the KDMI presented here is based on the object oriented programming concept which allows to have one object definition (workflow) and infinite numbers of object instances (data). Each definition is created by a graphical user interface and produces XML output stored in a database using a generic data model. On creation of a data instance the KDMI translates the definition into web forms for the scientist, the generic data model then accepts all information input following the given data provenance definition. An important aspect of the implementation phase is the possibility of a successive transition from daily measurement routines resulting in single spreadsheet files with well known points of failure and limited reuseability to a central infrastructure as a

Eastern equatorial Pacific sea surface temperature annual cycle in the Kiel climate model: simulation benefits from enhancing atmospheric resolution

2018-05-01

A long-standing difficulty of climate models is to capture the annual cycle (AC) of eastern equatorial Pacific (EEP) sea surface temperature (SST). In this study, we first examine the EEP SST AC in a set of integrations of the coupled Kiel Climate Model, in which only atmosphere model resolution differs. When employing coarse horizontal and vertical atmospheric resolution, significant biases in the EEP SST AC are observed. These are reflected in an erroneous timing of the cold tongue's onset and termination as well as in an underestimation of the boreal spring warming amplitude. A large portion of these biases are linked to a wrong simulation of zonal surface winds, which can be traced back to precipitation biases on both sides of the equator and an erroneous low-level atmospheric circulation over land. Part of the SST biases also is related to shortwave radiation biases related to cloud cover biases. Both wind and cloud cover biases are inherent to the atmospheric component, as shown by companion uncoupled atmosphere model integrations forced by observed SSTs. Enhancing atmosphere model resolution, horizontal and vertical, markedly reduces zonal wind and cloud cover biases in coupled as well as uncoupled mode and generally improves simulation of the EEP SST AC. Enhanced atmospheric resolution reduces convection biases and improves simulation of surface winds over land. Analysis of a subset of models from the Coupled Model Intercomparison Project phase 5 (CMIP5) reveals that in these models, very similar mechanisms are at work in driving EEP SST AC biases.

Starting in 1999, the University Cooperation Platform (UCP) implemented an exchange program of researchers and clinicians/physicists between the Christian-Albrechts-University Kiel in Germany and Chiang Mai University in Thailand, to initiate a sustainable base for long-term development of image-guided brachytherapy and in general for high-technology radiotherapy in Chiang Mai. A series of UCP protocols, based constructively on each other, were performed and evaluated at intermediate term follow-up. The first protocol, addressing computed tomography (CT)-optimized brachytherapy for advanced cervical cancer (n = 17), showed a significant reduction of D2cc for the bladder and sigmoid (p 80 Gy for bladder in only 17.2% versus 62.1% in conventional planning, and in rectum EQD2 > 75 Gy in 44.8% versus 79.3%, respectively. In conclusion, analyses revealed excellent results for the high-dose-rate IGBT in patients with advanced gynecological cancer both by using CT and MRI, and/or the combination with WP-IMRT. They also define MRI as gold standard for soft tissue assessment and to determine more accurately HR-CTV. The use of TAUS-guidance adds quality aspects to the "classical" conventional X-ray based planning, especially in terms of real-time measures and adequate soft tissue information, and may lower significantly the dose in OARs. The review of all UCP-results reconfirms the importance of the established program that will continue to operate with subsequent projects.

Alleviating tropical Atlantic sector biases in the Kiel climate model by enhancing horizontal and vertical atmosphere model resolution: climatology and interannual variability

Science.gov (United States)

Harlaß, Jan; Latif, Mojib; Park, Wonsun

2018-04-01

We investigate the quality of simulating tropical Atlantic (TA) sector climatology and interannual variability in integrations of the Kiel climate model (KCM) with varying atmosphere model resolution. The ocean model resolution is kept fixed. A reasonable simulation of TA sector annual-mean climate, seasonal cycle and interannual variability can only be achieved at sufficiently high horizontal and vertical atmospheric resolution. Two major reasons for the improvements are identified. First, the western equatorial Atlantic westerly surface wind bias in spring can be largely eliminated, which is explained by a better representation of meridional and especially vertical zonal momentum transport. The enhanced atmospheric circulation along the equator in turn greatly improves the thermal structure of the upper equatorial Atlantic with much reduced warm sea surface temperature (SST) biases. Second, the coastline in the southeastern TA and steep orography are better resolved at high resolution, which improves wind structure and in turn reduces warm SST biases in the Benguela upwelling region. The strongly diminished wind and SST biases at high atmosphere model resolution allow for a more realistic latitudinal position of the intertropical convergence zone. Resulting stronger cross-equatorial winds, in conjunction with a shallower thermocline, enable a rapid cold tongue development in the eastern TA in boreal spring. This enables simulation of realistic interannual SST variability and its seasonal phase locking in the KCM, which primarily is the result of a stronger thermocline feedback. Our findings suggest that enhanced atmospheric resolution, both vertical and horizontal, could be a key to achieving more realistic simulation of TA climatology and interannual variability in climate models.

Ludwik Zamenhof (1859-1917), born in Poland, invented and propagated Esperanto - an artificial, easy-to-learn language. Literally meaning "language of hope," Esperanto was constructed to avoid misunderstandings, establish communication and facilitate harmony among different nationalities. Simply, he wanted people to accept one another despite observed differences. He was a skilled ophthalmologist, but figuratively, he wished to heal the eyes of humankind to look without hate, just as the biblical Tobias removed the cataract from the corners of his father's eyes to restore his sight.

Adam Zamenhof was greatly influenced by his father, Ludwik Zamenhof, who designed the international language Esperanto. Like his father, he became an ophthalmologist and joined the Esperanto movement. He published in the field of ophthalmology and was soon chosen as head of an ophthalmology department. He subsequently became Chief of the Orthodox Jewish Hospital at Czystem in Warsaw. He was active in the leadership of the Bialystok-Warsaw Chamber of Medical Doctors. He perished in the Nazi Holocaust (Shoah) but all Zamenhof's ideals that Adam served as a doctor and social activist remain still alive.

This article presents the design and implementation of a new data acquisition system to be used as replacement for the old ones that have been in use with neutron monitors for the last decades and, which are eventually becoming obsolete. This new system is also intended to be used in new installations, enabling these scientific instruments to use today's communication networks to send data and receive commands from the operators. This system is currently running in two stations: KIEL2, in the Christian-Albrechts-Universität zu Kiel, Kiel, Germany, and CALMA, in the Castilla-La Mancha Neutron Monitor, Guadalajara, Spain

In Lituania, during the second mid-nineteenth century, a Polish and Jewish ophtalmologist, doctor Zamenhof (1859-1917) created an universal and non-national language, he called "esperanto". This "a posteriori" language, constituted from various indo-european existing roots, was the essential tool, the first step to abolish the differences between human ethnies, nationalities and religions. This project aimed to instaure universal fraternity, Zamenhof strongly wished. Using paper and electronic (available on esperanto.org website) sources, the paper analyzes what were Zamenhof's life and works. In a next study, his universal approach will be put back in the ideological context of the period.

Ludwik Zamenhof: a major contributor to world culture, on the 150(th) anniversary of his birth.

2010-01-01

More than 200 universal languages have been proposed to replace the nearly 3,000 existing languages. Esperanto, developed by the Polish-Jewish ophthalmologist Ludwik Zamenhof in 1887, became the most widely used artificial language of the 20(th) century. It is estimated that between one million and 15 million people in the world can speak or read Esperanto. Zamenhof was nominated 14 times for the Nobel Peace Prize, and also received the French Legion of Honor, and the Medal of Isabelle of Spain the Catholic. Ludwik Zamenhof started his professional training in ophthalmology at the Jewish Hospital in Warsaw, later spent several months in Vienna, and finally started a private ophthalmology practice in Warsaw, where he remained for most of his life. His son Adam was an associate professor of ophthalmology at the University of Warsaw and head of ophthalmology in the Jewish Hospital in Czyste, the biggest and most modern hospital in Warsaw at that time. Some lesser known aspects of Zamenhof's life and work drawn from the original 19(th) century Russian and 20(th) century Esperanto documents are described. Copyright 2010 Elsevier Inc.

The Zamenhof family is famous for Dr Ludwik Lejzer Zamenhof (1859-1917), who created the artificial language Esperanto and who initiated a social movement for peace and against any sort of discrimination. Ludwik was an ophthalmologist. Adam, Leon, Alexander, and Julian Zamenhof were medical doctors and noted surgeons, while Sophia Zamenhof was a paediatrician. Ludwik Zamenhof often referred to the biblical story of the Tower of Babel, in which diversity of languages was the punishment for builders who were arrogant and uncaring. With the help of Esperanto, the Zamenhofs metaphorically wanted to overcome the curse of Babel and restore the sense of human unity.

Language Planning and Planned Languages: How Can Planned Languages Inform Language Planning?

Directory of Open Access Journals (Sweden)

Humphrey Tonkin

2015-04-01

Full Text Available The field of language planning (LP has largely ignored planned languages. Of classic descriptions of LP processes, only Tauli (preceded by Wüster suggests that planned languages (what Wüster calls Plansprache might bear on LP theory and practice. If LP aims "to modify the linguistic behaviour of some community for some reason," as Kaplan and Baldauf put it, creating a language de novo is little different. Language policy and planning are increasingly seen as more local and less official, and occasionally more international and cosmopolitan. Zamenhof's work on Esperanto provides extensive material, little studied, documenting the formation of the language and linking it particularly to issues of supranational LP. Defining LP decision-making, Kaplan & Baldauf begin with context and target population. Zamenhof's Esperanto came shortly before Ben-Yehuda's revived Hebrew. His target community was (mostly the world's educated elite; Ben-Yehuda's was worldwide Jewry. Both planners were driven not by linguistic interest but by sociopolitical ideology rooted in reaction to anti-Semitism and imbued with the idea of progress. Their territories had no boundaries, but were not imaginary. Function mattered as much as form (Haugen's terms, status as much as corpus. For Zamenhof, status planning involved emphasis on Esperanto's ownership by its community - a collective planning process embracing all speakers (cf. Hebrew. Corpus planning included a standardized European semantics, lexical selectivity based not simply on standardization but on representation, and the development of written, and literary, style. Esperanto was successful as linguistic system and community language, less as generally accepted lingua franca. Its terminology development and language cultivation offers a model for language revival, but Zamenhof's somewhat limited analysis of language economy left him unprepared to deal with language as power.

The Kiel Science Factory (Kieler Forschungswerkstatt) is a school and teaching laboratory, which breaches the gap between school education and university research. Since opening in October 2012, 3.430 pupils worked at the Kiel Science Factory, and joined the different programs (ocean:lab, nano:lab, geo:lab), the numbers of visitors are increasing. The combination of experts in research and experts in education is very effective to attract young peoplés interest for a scientific career, to communicate science and to increase interest of teachers in current science. The biggest lab is the ocean:lab, it is jointly offered by Kiel University, Cluster of Excellence "Future Ocean" and Leibniz Institute for Science and Mathematics Education at Kiel University (IPN). The ocean:lab is addressing to school classes from grade 3 to 13, and it is strongly involved in pre-service teacher education. Appropriate to their respective level of study, pupils and students get fascinating insights into marine sciences and the working methods of real scientists. Furthermore teacher trainings and summer schools are producing an enthusiasm, which affects as well teachers as their students. The visiting pupils are mainly from Northern Germany, but also from e.g. Austria, Poland and Japan. Topics are the ocean as an ecosystem and how it is affected by anthropogenic impacts. The program offers an integrated investigation of the ecosystem "ocean" (from Plankton to marine mammals) with an interdisciplinary focus on biological aspects and abiotic factors of the habitat. In addition to pollution of the ocean through plastic waste and noise, the effects of climate change and eutrophication plays a role in discussions and tasks. New formats (e.g. an international Citizen Science Project and Expeditionary Learning) are carried out. The developed material is part of expedition boxes, which can be borrowed for project work in schools and science centers. http://www.forschungs-werkstatt.de/

Calcifying invertebrates succeed in a naturally CO2-rich coastal habitat but are threatened by high levels of future acidification

Directory of Open Access Journals (Sweden)

M. Wahl

2010-11-01

Full Text Available CO2 emissions are leading to an acidification of the oceans. Predicting marine community vulnerability towards acidification is difficult, as adaptation processes cannot be accounted for in most experimental studies. Naturally CO2 enriched sites thus can serve as valuable proxies for future changes in community structure. Here we describe a natural analogue site in the Western Baltic Sea. Seawater pCO2 in Kiel Fjord is elevated for large parts of the year due to upwelling of CO2 rich waters. Peak pCO2 values of >230 Pa (>2300 μatm and pHNBS values of pCO2 values are ~70 Pa (~700 μatm. In contrast to previously described naturally CO2 enriched sites that have suggested a progressive displacement of calcifying auto- and heterotrophic species, the macrobenthic community in Kiel Fjord is dominated by calcifying invertebrates. We show that blue mussels from Kiel Fjord can maintain control rates of somatic and shell growth at a pCO2 of 142 Pa (1400 μatm, pHNBS = 7.7. Juvenile mussel recruitment peaks during the summer months, when high water pCO2 values of ~100 Pa (~1000 μatm prevail. Our findings indicate that calcifying keystone species may be able to cope with surface ocean pHNBS values projected for the end of this century when food supply is sufficient. However, owing to non-linear synergistic effects of future acidification and upwelling of corrosive water, peak seawater pCO2 in Kiel Fjord and many other productive estuarine habitats could increase to values >400 Pa (>4000 μatm. These changes will most likely affect calcification and recruitment, and increase external shell dissolution.

Generalized Hurst exponent and multifractal function of original and translated texts mapped into frequency and length time series

Science.gov (United States)

Ausloos, M.

2012-09-01

A nonlinear dynamics approach can be used in order to quantify complexity in written texts. As a first step, a one-dimensional system is examined: two written texts by one author (Lewis Carroll) are considered, together with one translation into an artificial language (i.e., Esperanto) are mapped into time series. Their corresponding shuffled versions are used for obtaining a baseline. Two different one-dimensional time series are used here: one based on word lengths (LTS), the other on word frequencies (FTS). It is shown that the generalized Hurst exponent h(q) and the derived f(α) curves of the original and translated texts show marked differences. The original texts are far from giving a parabolic f(α) function, in contrast to the shuffled texts. Moreover, the Esperanto text has more extreme values. This suggests cascade model-like, with multiscale time-asymmetric features as finally written texts. A discussion of the difference and complementarity of mapping into a LTS or FTS is presented. The FTS f(α) curves are more opened than the LTS ones.

CliSO is implemented in their core curricula with the intention to foster students’ medical examination skills at the preclinical and clinical level. Methods: Both partners contributed their special competencies in the fields of case-based learning (Munich: CASUS e-learning platform and systematic learning (Kiel: Nickels e-learning platform. The didactic concept comprises the integration of theory and practice. It combines the standardized teaching of the following three components: Clinical skills are trained and reviewed in face-to-face courses. In the e-learning environment, the well-directed combination of case-based and systematic learning together with the chosen diversity of media (video, audio, animation facilitates situated learning as well as the intelligible presentation of clinical skills and their biomedical background. Both faculties agreed on joint learning objectives and standards. Results and prospects: It was possible to apply the concept to the different target groups at both faculties (first and second study phases and the differently designed face-to-face courses (Kiel: students examine each other; Munich: patients are examined in addition.

Some notes on "Leaves of Memory", the autobiography of Hermann Kobold

Science.gov (United States)

Vollmer, R.; Vollmer, H.; Duerbeck, H. W.

2004-12-01

We briefly describe the life of the astronomer Hermann Kobold, who lived from 1858 to 1942. He worked at the observatories of O'Gyalla, Strasbourg and Kiel, and was also involved in the observations and reductions of the German Venus transit project, 1874/82. His autobiography spans the time between his youth and his leave from Strasbourg in 1902. The subsequent time as observer and professor in Kiel and long-time editor of the Astronomische Nachrichten is not covered. The autobiography "Blaetter der Erinnerung" (Leaves of memeory), presented in the subsequent article, was written in his late age when he was already blind, using a special device. We also present some photographs of Kobold and his contemporaries, taken in Gottingen, O'Gyalla, Aiken (South Carolina), and Strasbourg.

BOOK REVIEW: "...eine ausnehmende Zierde und Vortheil"

Science.gov (United States)

Duerbeck, H. W.; Luehning, F.

This book comprises the habilitation thesis submitted by F. Lühning to the Faculty of Mathematics of Hamburg University in 2004. Due to financial support from various organizations, it was issued in a very attractive form as a special publication of the Society for the history of the city of Kiel. The nice layout, the graphical sketches of buildings, instruments, and astronomical connexions, often designed by the author, and the scientifically precise text, written with a sense of humor, make a pleasant reading, in spite of sometimes quite extensive descriptions of architectural details or 'operating instructions' for meridan circles etc. I have rarely read such an appealing text on astronomical history. The single chapters deal with the beginnings of astronomy in Kiel (1770-1820), Schrader's giant telescope from the late 18th century, Altona Observatory (1823-1850), the first years of the Astronomische Nachrichten, the last years of Altona Observatory (1850-1872), Bothkamp Observatory (1870-1914), the genesis of Kiel Observatory (1874-1880), the era of Krueger (1880-1896), the Kiel Chronometer Observatory (1893-1913), the era of Harzer (1897-1925), the era of Rosenberg (1927-1934), the decline of Kiel Observatory (1935-1950), and the Astronomische Nachrichten under Kobold (1907-1938). The book is concluded with a glossary of technical terms, biographical sketches of known and unknown dramatis personae, as well as a list of references. The author outlines lively sketches of people that were astronomically active in Altona, Kiel and its surroundings over a time interval of 200 years. To achieve this task, he has studied many files from the Secret State Archive Preussischer Kulturbesitz (Berlin), the Schleswig-Holsteinisches State Archive (Schleswig) and the Hamburg State Archive, from which he quotes extensively. He also has evaluated private documents and has interviewed surviving witnesses of the 1930s and 1940s. He has located remote sources: for example, the

The German Research Foundation (DFG) funds Collaborative Research Centres (CRCs - in German: Sonderforschungsbereiche SFBs) that are generally applied for by one university, but may also incorporate neighbouring universities or non-university research institutions. SFBs are crossing the boundaries of disciplines, as well as faculties, departments, institutions and institutes. The funding of an SFB can be up to 12 years (3 x 4 years). Kiel University and GEOMAR Helmholtz Centre for Ocean Research Kiel received funding for the SFB 754 'Climate-biogeochemical interactions in the tropical ocean' in 2008. Currently, the centre is in its third phase comprising 17 scientific subprojects, one outreach project, a central coordination and management subproject and a subproject covering the research expeditions with a total project budget of 12 Mio Euro. Around 100 scientists of interdisciplinary research fields (e.g. physical oceanography, micro-biology, palaeontology, chemistry, modelling) are actively involved. Besides generating high profile research, gender equality, early career support and data management are complementary goals of SFBs requested by the DFG. Within the SFB 754 the scientific coordination office is responsible for developing concepts and strategies to cover these additional requirements and over the past eight years the SFB 754 has been successful in setting up profound programmes and various measures. Some of the SFB 754 practices have been taken up by other projects, and hence allowed the SFB 754 to serve as a role model for 'best practice' within marine sciences in Kiel. A main reason for the success of the SFB 754 to work towards the additional goals set out in the DFGs SFB programme is that the project is well tied into existing structures and builds upon outstanding management expertise available in Kiel. Three examples are highlighted here: • young scientists programme (closely linked to a graduate school (Integrated School of Marine Sciences

Observation of γ rays > 1015 eV from Cygnus X-3

The X-ray binary system Cygnus X-3 is a source of particular interest. As well as emitting X-rays which are modulated with a 4.8-h period, it has been observed in 30-100 MeV γ rays by the SAS II satellite and several groups have detected γ rays in the TeV range showing the same period. Most recently, using the small extensive air shower array at Kiel, workers have found that the γ-ray spectrum of Cygnus X-3 extends above 2 x 10 15 eV, with an integral flux of (7.4 +- 3.2) x 10 -14 cm -2 s -1 . This paper confirms the Kiel observations and presents evidence that the γ-ray spectrum of Cygnus X-3 steepens above 10 16 eV. (author)

The larger foraminifera of the lower part of the Jafnayn Formation outcropping in the Wadi Sayq, in the Paleocene series of the eastern Oman Mountains, have been studied and described in detail. The analysis have allowed us to develop a detailed systematic description of each taxa, constraining their biostratigraphic distribution and defining the associated foraminifera assemblages. The taxonomic study has permitted us to identify each morphotype precisely and describe three new taxa, namely, Ercumentina sayqensis n. gen. n. sp. Lacazinella rogeri n. sp. and Globoreticulinidae new family. The first assemblage is characterized by the presence of Coskinon sp., Dictyoconus cf. turriculus Hottinger and Drobne, Anatoliella ozalpiensis Sirel, Ercumentina sayqensis n. gen. n. sp.

Applicability of colour index calibrations to T Tauri stars

Science.gov (United States)

Schöning, T.; Ammler, M.

2008-01-01

We examine the applicability of effective temperature scales of several broad band colours to T Tauri stars (TTS). We take into account different colour systems as well as stellar parameters like metallicity and surface gravity which influence the conversion from colour indices or spectral type to effective temperature. For a large sample of TTS, we derive temperatures from broad band colour indices and check if they are consistent in a statistical sense with temperatures inferred from spectral types. There are some scales (for V-H, V-K, I-J, J-H, and J-K) which indeed predict the same temperatures as the spectral types and therefore can be at least used to confirm effective temperatures. Furthermore, we examine whether TTS with dynamically derived masses can be used for a test of evolutionary models and effective temperature calibrations. We compare the observed parameters of the eclipsing T Tauri binary V1642 Ori A to the predictions of evolutionary models in both the H-R and the Kiel diagram using temperatures derived with several colour index scales. We check whether the evolutionary models and the colour index scales are consistent with coevality and the dynamical masses of the binary components. It turns out that the Kiel diagram offers a stricter test than the H-R diagram. Only the evolutionary models of \\cite {BCAH98} with mixing length parameter α=1.9 and of \\cite{DM94,DM97} show consistent results in the Kiel diagram in combination with some conversion scales of \\cite{HBS00} and of \\cite{KH95}.

Investigation concerning the existence of quarks near the nuclei of great air showers with the help of a cloud chamber

International Nuclear Information System (INIS)

Wiemken, U.

1974-01-01

In order to compare the results of McCusker's (1969) experiment, this paper presents an experiment with improved technical details. For this purpose, a large cloud chamber in connection with the Kiel air shower set-up was available. First, the expected quark induced ionisation has been determined by a calibration measurement on minimum ionising muons. These data are in extremely good agreement with values from the literature. Then, measurements in air showers with a mean primary energy of 10 16 eV have been performed during an effective measuring time of 66 days. The mean distance from the nucleus amounts to about 9 m. In contradiction to the quark abundance of McCusker, which predicts six quarks for the Kiel set-up, no track was found with 'quark suspicion'. Some tracks with low droplet densities could be explained already in a preliminary stage of the evaluation by normal cloud chamber effects. (orig.) [de

Measuring complexity with multifractals in texts. Translation effects

International Nuclear Information System (INIS)

Ausloos, M.

2012-01-01

Highlights: ► Two texts in English and one in Esperanto are transformed into 6 time series. ► D(q) and f(alpha) of such (and shuffled) time series are obtained. ► A model for text construction is presented based on a parametrized Cantor set. ► The model parameters can also be used when examining machine translated texts. ► Suggested extensions to higher dimensions: in 2D image analysis and on hypertexts. - Abstract: Should quality be almost a synonymous of complexity? To measure quality appears to be audacious, even very subjective. It is hereby proposed to use a multifractal approach in order to quantify quality, thus through complexity measures. A one-dimensional system is examined. It is known that (all) written texts can be one-dimensional nonlinear maps. Thus, several written texts by the same author are considered, together with their translation, into an unusual language, Esperanto, and asa baseline their corresponding shuffled versions. Different one-dimensional time series can be used: e.g. (i) one based on word lengths, (ii) the other based on word frequencies; both are used for studying, comparing and discussing the map structure. It is shown that a variety in style can be measured through the D(q) and f(α) curves characterizing multifractal objects. This allows to observe on the one hand whether natural and artificial languages significantly influence the writing and the translation, and whether one author’s texts differ technically from each other. In fact, the f(α) curves of the original texts are similar to each other, but the translated text shows marked differences. However in each case, the f(α) curves are far from being parabolic, – in contrast to the shuffled texts. Moreover, the Esperanto text has more extreme values. Criteria are thereby suggested for estimating a text quality, as if it is a time series only. A model is introduced in order to substantiate the findings: it consists in considering a text as a random Cantor set

Full Text Available The article studies word formation of the derogatory marked ethnonyms (DME of the Canadian, Australian and New Zealand English Language. DME are classified according to the method of word formation, the type of semantic transfer and deliberate phonetic distortion. Selection of the analyzed units is made out of such lexicographical sources as online dictionary of colloquial vocabulary Urban Dictionary, online dictionary Oxford English Dictionary, Merriam-Webster Online: Dictionary and Thesaurus, ABBYY Lingvo, The Free Dictionary, Dictionary.com, electronic databases The Racial slur Database and Hatebase, lists of ethnonyms from online resources canadaka.com, fact-index.com and other sources of factual materials. The urgent character of the given article is caused by lack of scientific study of the ways of word formation of DME, particularly, the units of Canadian, Australian and New Zealand English. Separation of the criteria of their description and division into groups are considered to be important.

Modelling and forecasting long-term dynamics of Western Baltic macrobenthic fauna in relation to climate signals and environmental change

Science.gov (United States)

Gröger, Joachim; Rumohr, Heye

2006-05-01

Long-term macrobenthos data from Kiel Bight in the Western Baltic collected between 1968 and 2000 have been correlated with the winter NAO index (North Atlantic Oscillation Index) and other environmental data such as temperature, salinity and oxygen content in the bottom water in order to detect systematic patterns related to so far unexplained abiotic signals in the dynamics of zoobenthic species assemblages. The benthos data come from a cluster of five stations (Süderfahrt/ Millionenviertel) in Kiel Bay. Our investigations concentrated on the macrobenthic dynamics with a focus on the number of species m - 2 (species richness). Using logarithms and the time series analysis approach of Box/Jenkins (ARIMA modelling, transfer function modelling) it was shown that species richness was strongly influenced by the winter NAO (adjusted for a linear time trend within the 1968-2000 period) and salinity (with a shift/lag of four years). Bootstrapping experiments (i.e. sampling from the error process) and analysis of prediction power (by means of the one- or more-years leaving-out method) showed that the parameter estimates behaved in a stable way, leading to a relatively robust model.

Stroemgren photometry of ZZ Ceti and other DA white dwarfs

International Nuclear Information System (INIS)

Fontaine, G.; Bergeron, P.; Lacombe, P.; Lamontagne, R.; Talon, A.

1985-01-01

Stroemgren colors for a sample of 71 stars classified as DA white dwarfs are presented. Comparison with the recent model atmospheres of the Kiel group indicates that the average gravity of 63 stars of the sample is log g = 7.98 +- 0.31, with no indication of a dependence on the effective temperature. This is consistent with the theoretical expectation that white dwarfs evolve at constant gravity. Correlations between Stroemgren colors and Greenstein multichannel colors are also given, using 52 stars that have been observed in common in the two systems. These correlations are used to compare the data with a second set of model atmospheres computed by Shipman. Contrary to what has been suggested in the past, no fundamental differences are found when confronting the Stroemgren data with the DA model atmospheres of Shipman or those of the Kiel group. Finally, observations of 11 pulsating objects reveal the existence of a narrow instability strip in the range 13 000 K> or approx. =T/sub e/> or approx. =11 000 K in a [(u-b), (b-y)] two-color diagram. The present results add evidence to the contention that all DA white dwarfs evolve to become ZZ Ceti pulsators in the instability strip

Bagatelle about translated theatre

Paolo Puppa

2017-07-01

Full Text Available In Italy, there is nothing in common, no harmony, between audience and stage, in particular, between language spoken out of the theatre and language pronounced on stage, in a way that playwrights often are compelled to invent their own language. In fact, Italian theater lacks a precise code of traditions able to shape the organic ground of recitation itself. These questions allow the author to reflect about theatrical language as in, for example, the case of a Venetian company that performs Danilo Kiš’ play, Consigli a un giovane scrittori, or the revision, among others, of the syncretic Esperanto used by Eugenio Barba.

Reviews in Modern Astronomy 28: From the First Quasars to Life-Bearing Planets - From Accretion Physics to Astrobiology

The current issue of AN is Volume 28 of the Reviews in Modern Astronomy and presents the Karl Schwarzschild Award Lecture, the Ludwig Bierman n Award Lecture and the Doctoral Thesis Award Lecture given at the 88th Annual International Scientific Meeting of the Astronomische Gesellschaft held in Kiel, Germany, September 14-18, 2015. It was the fifth time that Kiel hosted a meeting of the AG, the first one was in 1887. In 2015 the fall meeting was a part of the celebrations of the 350th anniversary of the Christiana Albertina University Kiel in 1665. For astronomers around the globe, the astrophysical group is well known for the Kieler Schule and its fundamental contributions to the physics of stellar atmospheres. Based on the work by Albrecht Unsöld during his tenure of 41 years as active researcher and lecturer (and many more after becoming emeritus), the quantitative analysis of stellar atmospheres and the reliable determination of chemical abundances is nowadays a cornerstone of modern astrophysics. Even more, it is of ground-laying importance for the whole field, from the characterization of exoplanets and their host stars to the properties of galaxies at cosmic dawn. The meeting was guided by the theme "From the First Quasars to Life-Bearing Planets -- From Accretion Physics to Astrobiology". The meeting was attended by almost 300 participants from around the world. The Karl Schwarzschild Medal 2015 of the Astronomische Gesellschaft was awarded to Professor Immo Appenzeller, Heidelberg. His lecture with the title "Astronomical technology -- the past and the future" opened the meeting. The talk presented by the Ludwig Biermann Award winner 2015, Dr. Ivan Minchev, Potsdam, dealt with the topic "Constraining the Milky Way assembly history with Galactic Archaeology". The Doctoral Thesis Award 2015 was awarded to Dr. Cornelia Müller (Würzburg). In her lecture she discussed the subject "Multiwavelength and parsec-scale properties of extragalactic Jets". The AG

A comparison of observed extreme water levels at the German Bight elaborated through an extreme value analysis (EVA) with extremes derived from a regionally coupled ocean-atmospheric climate model (MPI-OM)

As a consequence of climate change atmospheric and oceanographic extremes and their potential impacts on coastal regions are of growing concern for governmental authorities responsible for the transportation infrastructure. Highest risks for shipping as well as for rail and road traffic originate from combined effects of extremes of storm surges and heavy rainfall which sometimes lead to insufficient dewatering of inland waterways. The German Ministry of Transport and digital Infrastructure therefore has tasked its Network of Experts to investigate the possible evolutions of extreme threats for low lands and especially for Kiel Canal, which is an important shortcut for shipping between the North and Baltic Seas. In this study we present results of a comparison of an Extreme Value Analysis (EVA) carried out on gauge observations and values derived from a coupled Regional Ocean-Atmosphere Climate Model (MPI-OM). High water levels at the coasts of the North and Baltic Seas are one of the most important hazards which increase the risk of flooding of the low-lying land and prevents such areas from an adequate dewatering. In this study changes in the intensity (magnitude of the extremes) and duration of extreme water levels (above a selected threshold) are investigated for several gauge stations with data partly reaching back to 1843. Different methods are used for the extreme value statistics, (1) a stationary general Pareto distribution (GPD) model as well as (2) an instationary statistical model for better reproduction of the impact of climate change. Most gauge stations show an increase of the mean water level of about 1-2 mm/year, with a stronger increase of the highest water levels and a decrease (or lower increase) of the lowest water levels. Also, the duration of possible dewatering time intervals for the Kiel-Canal was analysed. The results for the historical gauge station observations are compared to the statistics of modelled water levels from the coupled

Surfaces exposed to a plasma experience a certain pressure that pushes them away from the volume. This effect has been investigated experimentally in a recent article by Thomas Trottenberg, Thomas Richter, and Holger Kersten from Kiel University/Germany [Eur. Phys. J. D 69, 91 (2015)]. The experimental results are impressive and have actually drawn the attention of the community to an interesting question which so far has been largely ignored. In addition to their experimental results the Kiel group proposes also a rough concept in order to explain their findings which provides certainly a basic qualitative understanding of the physical processes involved. However, on a closer inspection the picture developed so far is not entirely satisfying and the problem seems to require a more fundamental approach. This comment shows that the effect of the wall pressure can be described exactly using only analytical methods. The physical situation is analyzed by three different approaches. First, the simple case of only one spatial dimension is presented in detail. Second, the case of spherical symmetry is analyzed by some simplifying assumptions in order to investigate the effect of higher dimensionality. Third, a formal derivation for arbitrary geometry is given. This general result includes the one-dimensional case but does not allow a convenient connection between the pressures at the wall and in the center. Finally, the results are summarized and some conclusions are drawn.

Revolution ohne Kiel und ohne Revolution – Die quantitativ-theoretische Geographie in Erlangen

K. Paulus

2017-10-01

Full Text Available This article aims at expanding the predominant narrative of a Quantitative Revolution in German-speaking geography, to develop a more complex and multifaceted perspective on this chapter of the discipline's history. For this purpose, I take a closer look at the institute of geography in Erlangen. Eugen Wirth, the long-term chair holder in Erlangen, argued that here, in contrast to the majority of other institutes, the implementation of quantitative methods started in 1932, when Walter Christaller submitted his thesis: Central Places in Southern Germany. According to Wirth a dissertation supervised by him in 1969 was a further step towards the use of quantitative methods. I argue that Wirth made a significant contribution to the debate on quantitative theoretical geography in Germany with his textbook Theoretical Geography published in 1979, although the book was subsequently criticised and strongly rejected by Bartels and others as a conservative embrace. By examining this local negotiation process, I develop one of many narratives, that stand opposed to a unified account with which the general assembly of geographers in 1969 and Bartels' Geographie des Menschen uniquely motivated the abandonment of the concept of Länderkunde.

Progress in Non-equilibrium Green's Functions (PNGF VI)

2016-01-01

The sixth interdisciplinary conference 'Progress in Non-equilibrium Green's Functions' (PNGF6) took place at Lund University, Sweden, on 17-21 August 2015. The conference was attended by 60 scientists, from Europe and overseas, sharing an interest in Green's function methods and/or non-equilibrium phenomena. At the conference, 34 invited and contributed talks were given, together with a poster session with 17 contributions. As its predecessors (Rostock 1999, Dresden 2002, Kiel 2005, Glasgow 2009, Jyväskylä 2012) did, the conference succeeded in gathering different communities for the exchange of recent developments and results. Among the topics of the conference, we mention approaches for strongly correlated systems, improvements of existing perturbative many-body schemes, electron-phonon/-photon interactions in time-dependent treatments, numerical scalability of NEGF approaches, connections with other non-equilibrium methods and concrete physical applications. For the latter, we mention quantum transport, semiconductor kinetics, multiply excited states in atoms and ions, nuclear reactions, high energy physics, quantum cascade lasers, strongly correlated model systems, graphene-nanostructures, optoelectronics, superconductors, spin-dynamics, photovoltaics, excitations in atoms and ions and time-resolved spectroscopy. The present volume contains 20 articles from participants of PNGF6, devoted to these topics. Compared to previous conferences, a completely novel and successful aspect of PNGF6 was the participation of experimentalists among the invited speakers, to establish a connection between emerging experimental techniques (for example, time-dependent spectroscopies) and the theoretical NEGF community. As at the previous PNGF conferences, the atmosphere was friendly and exciting at the same time, favoring vivid and stimulating discussions among experienced scientists, young researchers and students.

The research project `Evaluation of Anthropogenic Urban Soils` was subsidized by the German Federal Ministry of Education, Science, Research and Technology and adviced by the working group `Stadtboeden` of the German Society of Soil Science. It was realized as a cooperation between the universities of Berlin (TU), Halle-Wittenberg, Hohenheim, Kiel and Rostock and had three objectives: - to characterize soils developed from anthropogenic substratums (`urban soils`), - to figure out distribution patterns of such soils and - to verify whether urban soils could be evaluated according to their filtering and habitat function in the same way as soils developed from natural parent material. Evaluation methods based on easily obtainable field data had to be adapted to `urban soils` respectively developed anew. For that reason some typical soils of anthropogenic lithogenesis had to be examined between 1993 and 1996 both on their importance as habitats for plants and soil organisms and on their filtering, buffering and transforming capacities for organic and inorganic pollutants. Accordingly representative `urban soils` were gathered in the towns of Berlin, Eckernfoerde, Essen, Halle, Kiel, Rostock and Stuttgart; these soils had developed from technogenic substratums (brick and mortar debris, municipal waste, ashes, slag, sludge) and redeposited alkaline resp. acidic natural substratums (mud, coal mine and coking plant deposits). Some of the soils were influenced by ground water, and all soils developed from the same kind of parent material belonged to different stages of development.

Várias classificações têm sido propostas em busca de um consenso entre patologistas e clínicos. Este trabalho teve como objetivo analisar criticamente três destas classificações através do estudo retrospectivo de 145 casos de linfomas primários de gânglio linfático selecionados do Serviço de Anatomia Patológica do Hospital Universitário Clementino Fraga Filho, entre 1979 e 1995. Os casos revistos foram classificados pelas propostas da Working Formulation, de Kiel e da Real. Testes imunoistoquímicos com os anticorpos anti-CD45, anti-CD20, anti-CD45RO e anti-CD30 foram realizados. Cento e sete casos (73,7% apresentaram fenótipo B; 33 casos (22,7%, fenótipo T; e quatro casos foram nulos (linfoma anaplásico de grandes células. Foi possível prever o fenótipo pela morfologia em 89,4% dos casos. Os linfomas de alto grau predominaram (59,2%, sendo o linfoma centroblástico o de maior freqüência (31,7% . Os linfomas foliculares representaram 29 casos (20%, com maior incidência dos de grandes células (31% do que dos de pequenas células (27,5%. Quando comparadas as três classificações, observamos que determinados grupos da Working Formulation abrigam múltiplas entidades. Isto se deve ao fato de a classificação da Working Formulation ser baseada somente em achados morfológicos e, por isso, deve ter seu uso desaconselhado. Já a classificação de Kiel e a da Real devem ter o seu emprego estimulado, pois apresentam, além de uma boa análise histopatológica, um estudo imunológico que define entidades biológicas correlacionando-se, quando possível, com a célula de origem.The non-Hodgkin's lymphomas classifications have been a controversial reason for the last thirty years.

The second group is not HPV associated and occurs often in elderly women without neoplastic epithelial disorders. Histology: Squamous cell carcinoma (SCC is the most common malignant tumor of the vulva (95%. Clinical features: Pruritus is the most common and long-lasting reported symptom of vulvar cancer, followed by vulvar bleeding, discharge, dysuria, and pain. Therapy: The gold standard for even a small invasive carcinoma of the vulva was historically radical vulvectomy with removal of the tumor with a wide margin followed by an en bloc resection of the inguinal and often the pelvic lymph nodes. Currently, a more individualized and less radical treatment is suggested: a radical wide local excision is possible in the case of localized lesions (T1. A sentinel lymph node (SLN biopsy may be performed to reduce wound complications and lymphedema. Prognosis: The survival of patients with vulvar cancer is good when convenient therapy is arranged quickly after initial diagnosis. Inguinal and/or femoral node involvement is the most significant prognostic factor for survival.

Full Text Available The long accepted complexity invariance of human languages has become controversial within the last decade. In investigations of the problem, both creole and planned languages have often been neglected. After a presentation of the scope of the invariance problem and the proposition of the natural to planned language continuum, this article will discuss the contribution of planned languages. It will analyze the complexity of Esperanto at the phonological, morphological, syntactic and semantic levels, using linguistic data bases. The role of the L2 speech community and development of the language will also be taken into account when discussing the endurance of the same level of simplicity of this planned international language. The author argues that complexity can be variable and to some extent planned and maintained.

Author identities an interoperability problem solved by a collaborative solution

Fleischer, D.; Czerniak, A.; Schirnick, C.

2012-12-01

The identity of authors and data providers is crucial for personalized interoperability. The marketplace of available identifiers is packed and the right choice is getting more and more complicated. Even though there are more then 15 different systems available there are still some under development and proposed to come up by the end of 2012 ('PubMed Central Author ID' and ORCID). Data Management on a scale beyond the size of a single research institute but on the scale of a scientific site including a university with student education program needs to tackle this problem and so did the Kiel Data Management an Infrastructure. The main problem with the identities of researchers is the quite high frequency changes in positions during a scientist life. The required system needed to be a system that already contained the potential of preregistered people with their scientific publications from other countries, institutions and organizations. Scanning the author ID marketplace brought up, that there us a high risk of additional workload to the researcher itself or the administration due to the fact that individuals need to register an ID for themselves or the chosen register is not yet big enough to simply find the right entry. On the other hand libraries deal with authors and their publications now for centuries and they have high quality catalogs with person identities already available. Millions of records internationally mapped are available by collaboration with libraries and can be used in exactly the same scope. The international collaboration between libraries (VIAF) provides a mapping between libraries from the US, CA, UK, FR, GER and many more. The international library author identification system made it possible to actually reach at the first matching a success of 60% of all scientists. The additional advantage is that librarians can finalize the Identity system in a kind of background process. The Kiel Data Management Infrastructure initiated a web service

Microwave and Submillimeter-Wave Measurements of HD 12C 16O in the ν 4, ν 5, and ν 6 Bands: Evidence of Vibrational Induced Rotational Axis Switching ("VIRAS")

The rotational spectrum of HDCO in the 4 1, 5 1, and 6 1 excited vibrational states has been investigated in Lille and Kiel using a sample enriched in deuterium. In Lille, the measurements were performed in the millimeter region (160-600 GHz). The spectra in Kiel were recorded using Fourier transform microwave spectrometers in the regions around 8-18 and 18-26 GHz, employing a rectangular waveguide of length 12 m and a circular waveguide of length 36 m, respectively. These results were combined with the 4 1, 5 1, and 6 1 infrared energy levels which were obtained from a previous analysis of FTS spectra of the ν 4 (CHD bend), ν 5 (CHD rocking), and ν 6 bands (out of plane bend) recorded in the 10-μm region at Giessen (A. Perrin, J.-M. Flaud, M. Smirnov, and M. Lock, J. Mol. Spectrosc.203, 175-187 (2000)). The energy level calculation of the 4 1, 5 1, and 6 1 interacting states accounts for the usual A- and B-type Coriolis resonances in the 5 1⇔6 1 and 4 1⇔6 1 off diagonals blocks. In addition, since the energy levels of the 5 1 and 6 1 states are very strongly resonating, it proved necessary, as in our previous study, to use a { Jx, Jz} nonorthorhombic term in the 5 1 and 6 1v-diagonal blocks of the Hamiltonian matrix in order to reproduce properly the observed microwave transitions and infrared energy levels. Therefore, this work confirms that HDCO is a good example of the vibrational induced rotational axis switching ("VIRAS") effect.

This paper provides a critical examination of electronic data interchange (EDI) standards and their application in different types of trading relationships. It argues that EDI standards are not directly comparable to more stable sets of technical standards in that they are dynamically tested...... and negotiated in use with each trading exchange. It takes the position that EDI standards are an emergent language form and must mean different things at the institutional and local levels. Using the lens of emergent linguistic analysis it shows how the institutional and local levels must always be distinct...... and yet can coexist. EDI standards can never represent the creation of an 'Esperanto of institutional communication'. Instead we believe that standards must be developed such that they support and accommodate general basic grammatical forms that can be customised to individual needs. The analysis...

The monitoring programmes set up in accordance with the directives for the surveillance of effluents from nuclear installations oblige operators of such installations to take samples of vegetation (grass) and soil twice a year at the least favourable place in the industrial plant's environment, and at a reference site, for radioactivity monitoring by gamma spectroscopy. In addition, the samples are to be examined for their Sr-90 content. Data recorded over the years show that nuclear facilities do not significantly contribute to soil and vegetation contamination with Sr-90 or Cs-137. The directives require regular interlaboratory comparisons, which are coordinated by the directing centre at Kiel. (DG) [de

Heinz Ludwig Ansbacher was born in Frankfurt, Germany, on October 21, 1904. He died at his home in Burlington, Vermont, on June 22, 2006, at the age of 101 years. Alfred Adler's influence led Ansbacher to the field of psychology, where he began a lifelong scholarship on the psychology of Alfred Adler. Among Heinz's distinctions and honors were being named a Fulbright lecturer at the University of Kiel, Germany, and serving as president of the North American Society of Adlerian Psychology. Many of us will remember Professor Ansbacher as a person who lived by Adlerian principles: encouraging others while helping them to find a goal in life.

The specific role of radiotherapy in the management of prostate carcinoma at different stages of tumor development

The study described here was based on the case reports of 135 patients of the Radiological Department at Kiel's University Hospital, who were treated for carcinomas of the prostate at any time during the period between 1965 and 1980. It was the aim of these evaluations to define the particular role of radiotherapy in the management of carcinomas of the prostate and to compare it to that of other methods of treatment (hormones, surgery). Percutaneous local irradiation of the carcinoma or irradiation of metastases were the criteria of inclusion into this retrospective study. The stage of the tumour was a decisive factor in the final analysis of the results. (orig.) [de

The He-3 high-pressure gas scintillation neutron detector commercially available as LND 800, has been compated to a Li-6 glass scintillator type NE 912. (n,γ) pulse height discrimination capabilities and neutron detection efficiencies have been determined. The objective of these measurements was to try to improve the Kiel Fast-Chopper TOF detector system by using a gasscintillator, which could cover the neutron beam geometry and by which gamma ray background contributions could be reduced. The time response always meets the requirements of a chopper experiment, but the neutron detection efficiency of the Li-6 glasses now used had to be maintained. (orig./HP) [de

In this study, we examined the therapeutic potential of localized release of diclofenac from electrospun nanofibers generated from poly(d,l-lactide-co-glycolide polymer. Diclofenac was chosen since anti-inflammatory agents that inhibit cyclooxygenase have shown great potential in their ability to directly inhibit tumor growth as well as suppress inflammation-mediated tumor growth. A mouse resection model of oral carcinoma was developed by establishing tumor growth in the oral cavity by ultrasound-guided injection of 1 million SCC-9 cells in the floor of the mouth. Following resection, mice were allocated into four groups with the following treatment: 1 no treatment, 2 implanted scaffolds without diclofenac, 3 implanted scaffolds loaded with diclofenac, and 4 diclofenac given orally. Small animal ultrasound and magnetic resonance imaging were utilized for longitudinal

Kidney transplantation is the treatment choice for patients with end-stage renal diseases. Because of good long-term outcome, pediatric kidney grafts are also accepted for transplantation in adult recipients despite a significant mismatch in body size and age between donor and recipient. These grafts show a remarkable ability of adaptation to the recipient body and increase in size in a very short period, presumably as an adaptation to hyperfiltration. We investigated renal graft growth as well as glomerular proliferation and differentiation markers Kiel-67, paired box gene 2 and Wilms tumor protein (WT1) expression in control biopsies from different transplant constellations: infant donor for infant recipient, infant donor for child recipient, infant donor for adult recipient, child donor for child recipient, child donor for adult recipient, and adult donor for an adult recipient. We detected a significant increase in kidney graft size after transplantation in all conditions with a body size mismatch, which was most prominent when an infant donated for a child. Podocyte WT1 expression was comparable in different transplant conditions, whereas a significant increase in WT1 expression could be detected in parietal epithelial cells, when a kidney graft from a child was transplanted into an adult. In kidney grafts that were relatively small for the recipients, we could detect reexpression of podocyte paired box gene 2. Moreover, the proliferation marker Kiel-67 was expressed in glomerular cells in grafts that increased in size after transplantation. Kidney grafts rapidly adapt to the recipient size after transplantation if they are transplanted in a body size mismatch constellation. The increase in transplant size is accompanied by an upregulation of proliferation and dedifferentiation markers in podocytes. The different examined conditions exclude hormonal factors as the key trigger for this growth so that most likely hyperfiltration is the key trigger inducing the

This study aimed to verify the reproduction of an aerobic test to determine nonexpert swimmers' resistance. The sample consisted of 24 male swimmers (age: 22.79 ± 3.90 years; weight: 74.72 ± 11.44 kg; height: 172.58 ± 4.99 cm; and fat percentage: 15.19% ± 3.21%), who swim for 1 hour three times a week. A new instrument was used in this study (a Progressive Swim Test): the swimmer wore an underwater MP3 player and increased their swimming speed on hearing a beep after every 25 meters. Each swimmer's heart rate was recorded before the test (BHR) and again after the test (AHR). The rate of perceived exertion (RPE) and the number of laps performed (NLP) were also recorded. The sample size was estimated using G*Power software (v 3.0.10; Franz Faul, Kiel University, Kiel, Germany). The descriptive values were expressed as mean and standard deviation. After confirming the normality of the data using both the Shapiro-Wilk and Levene tests, a paired t-test was performed to compare the data. The Pearson's linear correlation (r) and intraclass coefficient correlation (ICC) tests were used to determine relative reproducibility. The standard error of measurement (SEM) and the coefficient of variation (CV) were used to determine absolute reproducibility. The limits of agreement and the bias of the absolute and relative values between days were determined by Bland-Altman plots. All values had a significance level of P 0.50 and ICC > 0.66. The SEM had a variation of ±2% and the CV was 0.90; SEM swimmers. The Progressive Swim Test for nonexpert swimmers produces comparable results for noncompetitive swimmers with a favorable degree of reproducibility, thus presenting possible applications for researching the physiological performance of nonexpert swimmers.

What do we need to know to predict ENSO? Student-centered learning in a Master course in Climate Physics

An important learning outcome of a Master of Sciences program is to empower students to understand which information they need, how they can gain the required knowledge and skills, and how to apply those to solve a given scientific problem. In designing a class on the El-Nino-Southern-Oscillation (ENSO) for students in the Climate Physics program at Kiel University, Germany, we have implemented various active learning strategies to meet this goal. The course is guided by an overarching question, embedded in a short story: What would we need to know to successfully predict ENSO? The students identify desired learning outcomes and collaboratively construct a concept map which then serves as a structure for the 12 weeks of the course, where each individual topic is situated in the larger context of the students' own concept map. Each learning outcome of the course is therefore directly motivated by a need to know expressed by the students themselves. During each session, students are actively involved in the learning process. They work individually or in small groups, for example testing different index definitions, analyzing data sets, setting up simple numerical models and planning and constructing hands-on experiments to demonstrate physical processes involved in the formation of El Niño events. The instructor's role is to provide the necessary background information and guide the students where it is needed. Insights are shared between groups as students present their findings to each other and combine the information, for example by cooperatively constructing a world map displaying the impacts of ENSO or by exchanging experts on different ENSO oscillator theories between groups. Development of this course was supported by the PerLe Fonds for teaching innovations at Kiel University. A preliminary evaluation has been very positive with students in particular appreciating their active involvement in the class.

2014-07-01

Full Text Available Daniar Kurmanbekovich Osmonov, Aleksey Aksenov, Andrea Nathaly Guerra Sandoval, Almut Kalz, Klaus Peter Juenemann Department of Urology and Pediatric Urology, University Hospital Schleswig-Holstein, Campus Kiel, Kiel, Germany Introduction: This paper reports treatment of a 76-hour low-flow priapism with a shunting procedure that was first described by Barry in 1976. We were able to observe the preservation of erectile function despite the long period of ischemia. A review of the literature shows that there are few reports of erectile function recovery after a priapism of similar duration. Materials and methods: A 42-year-old patient presented with a 76-hour priapism, probably caused by consumption of alcohol and illegal drugs. A Barry Shunt procedure was performed. The erectile function of the patient was assessed by means of International Index of Erectile Function score over a follow-up period of 30 months. Moreover, we reviewed different surgical options for treatment of priapism in the literature. Results: Partial return of erection without sexual arousal occurred on two occasions during the 10-day hospitalization, but was treated by manipulation of the penis, ie, by milking the tumescence into the shunt. After 3 months, the shunt was still palpable as a subcutaneous swelling. Six months postoperatively, the residual swelling had disappeared. The International Index of Erectile Function score was of 21 without phosphodiesterase type 5 inhibitors after a follow-up of 2.5 years. Conclusion: Barry shunt is an effective alternative surgical option for the treatment of low-flow priapism. In the case of our patient, it was also effective after a 76-hour-lasting priapism. Keywords: low flow priapism, erectile function, cavernovenous shunt, surgical treatment of stuttering priapism

Urban soils often have high concentrations of heavy metals. This is particularly true of the technogenic substrates often found in cities and industrial and trading estates. The aim of the present project was therefore to mitigate the deficits of our present knowledge on problems relating to heavy metals in technogenic substrates. The studies presented in the following were carried out in pursuit of the following tasks: determination of the total concentration and mobility of the elements Cu, Pb, Cd, Zn, and Ni in 11 lead soil profiles from technogenic substrates in Rostock, Kiel, Eckernfjoerde and Halle/Saale; study of the dependence of heavy metal mobility on different soil characteristics (e.g. pH, clay, organic carbon, and total heavy metal content); recording of adsorption isotherms characterising the sorption and desorption behaviour of heavy metals; estimation of the heavy metal binding capacity of technogenic substrates following the method quoted by DVWK (1988) for heavy metals; and performance of percolation experiments on soil columns for deriving material transport parameters and of model calculations on heavy metal migration. [Deutsch] Urbane Boeden, besonders die in Staedten, Industrie- und Gewerbegebieten verbreitet lagernden technogenen Substrate, weisen oft hohe Schwermetallgehalte auf. Ziel dieses Projektes ist daher, Erkenntnisdefizite zur Schwermetallproblematik technogener Substrate zu verringern.

2016-04-01

This poster is linked to the oral presentation by Dr. Christiane K. Schelten. One requirement of a successful application for funding under the DFGs Collaborative Research Centres (SFBs) programme is to integrate a strategy to increase the number of female principal investigators and to support younger women scientists in pursuing their academic career. The DGF provides a lump sum of 30.000 € per year for measures to promote women scientists, to raise awareness for gender imbalances and to create a family friendly working environment. The SFB 754 'Climate - Biogeochemistry Interactions in the Tropical Ocean' based at Kiel University and the GEOMAR Helmholtz Centre for Ocean Research developed an innovative strategy to develop and implement new measures for more gender equality within the SFB 754 by building on existing expertise and structures. Together with the Cluster of Excellence 'The Future Ocean' (funded within the German Excellence Initiative), the SFB 754 finances the position of a coordinator for gender measures based at Kiel University's Central Office for Gender Equality, Diversity & Family. Due to this close cooperation of SFB 754 coordination and the university's gender office a successful framework for the SFB 754 gender equality activities has been developed. Measures taken are both integrated into the overall activities of the university, and tailored to the needs of women scientists in marine sciences in general, in the SFB 754 in particular. One outcome of this successful cooperation is, for example, the via:mento_ocean programme, the marine science focused line of the university's mentoring programme via:mento for female postdocs. But the SFB 754 also offers internal workshops and plenary presentations to raise gender awareness within the whole SFB 754 community and trainings to its female doctoral students and postdocs such as a very successful 'assertiveness and self-defence training'.

Very sensitive analytical methods for I-129 were developed for different sample materials. - The behaviour of I-129 in the Karlsruhe reprocessing plant and its release was completely investigated. - A longterm risk for the population caused by I-129 is not excpected. An existing environmental contamination with I-129 is reduced by a half-life of 0,3 y. The exposure of the population via the pasture-cow-milk path until now was overstimated at least by a factor 45. - In the environmental air of Kiel, Stade, Karlsruhe, Gundremmingen and Munich elemental iodine and iodine aerosols were measured. In the environmental air of Karlsruhe CH 3 127 I was determined. (orig./RW) [de

SFB754 - data management in large interdisciplinary collaborative research projects: what matters?

Science.gov (United States)

Mehrtens, Hela; Springer, Pina; Schirnick, Carsten; Schelten, Christiane K.

2016-04-01

Data management for SFB 754 is an integral part of the joint data management team at GEOMAR Helmholtz Centre for Ocean Research Kiel, a cooperation of the Cluster of Excellence "Future Ocean", the SFB 754 and other current and former nationally and EU-funded projects. The coalition successfully established one common data management infrastructure for marine sciences in Kiel. It aims to help researchers to better document the data lifecycle from acquisition to publication and share their results already during the project phase. The infrastructure is continuously improved by integration of standard tools and developing extensions in close cooperation with scientists, data centres and other research institutions. Open and frequent discussion of data management topics during SFB 754 meetings and seminars and efficient cooperation with its coordination office allowed gradual establishment of better data management practices. Furthermore a data policy was agreed on to ensure proper usage of data sets, even unpublished ones, schedules data upload and dissemination and enforces long-term public availability of the research outcome. Acceptance of the infrastructure is also backed by easy usage of the web-based platform for data set documentation and exchange among all research disciplines of the SFB 754. Members of the data management team act as data curators and assist in data publication in World Data Centres (e.g. PANGAEA). Cooperation with world data centres makes the research data then globally searchable and accessible while links to the data producers ensure citability and provide points of contact for the scientific community. A complete record of SFB 754 publications is maintained within the institutional repository for full text print publications by the GEOMAR library. This repository is strongly linked with the data management information system providing dynamic and up-to-date overviews on the various ties between publications and available data sets

Ooishi's Observation: Viewed in the Context of Jet Stream Discovery.

Science.gov (United States)

Lewis, John M.

2003-03-01

Although aircraft encounters with strong westerly winds during World War II provided the stimulus for postwar research on the jet stream, Wasaburo Ooishi observed these winds in the 1920s. Ooishi's work is reviewed in the context of earlier work in upperair observation and postwar work on the jet stream. An effort is made to reconstruct Ooishi's path to the directorship of Japan's first upper-air observatory by reliance on historical studies and memoirs from the Central Meteorological Observatory.Archival records from Japan's Aerological Observatory have been used to document Ooishi's upperair observations. The first official report from the observatory (written in 1926 and in the auxiliary language of Esperanto) assumes a central role in the study. In this report, data are stratified by season and used to produce the mean seasonal wind profiles. The profile for winter gives the first known evidence of the persistent strong westerlies over Japan that would later become known as the jet stream.

Galactic cosmic rays are entering the heliosphere from the interstellar medium, while anomalous cosmic rays are believed to be pickup ions accelerated at the heliospheric termination shock. Both particle species are modulated by the solar wind and the heliospheric magnetic field. Since 1997 solar activity increased and as a consequence the flux of galactic and anomalous cosmic ray decreased. In this paper we will discuss the variation of low energy anomalous cosmic rays as measured by the Ulysses Energetic Particle Composition Experiment (EPAC) and the Kiel Electron Telescope (KET) on board Ulysses. Specifically we are addressing the question: Are there differences in the modulation of galactic and anomalous cosmic rays and what are possible implication for the modulation of cosmic rays in the heliosphere?

Advanced supersonic nozzle concepts are currently under investigation, utilizing multiple bypass streams and airframe integration to bolster performance and efficiency. This work focuses on the parametric study of a supersonic, multi-stream jet with aft deck. The single plane of symmetry, rectangular nozzle, displays very complex and unique flow characteristics. Flow visualization techniques in the form of PIV and schlieren capture flow features at various deck lengths and Mach numbers. LES is compared to the experimental results to both validate the computational model and identify limitations of the simulation. By comparing experimental results to LES, this study will help create a foundation of knowledge for advanced nozzle designs in future aircraft.

Full Text Available Background. Kidney transplantation is the treatment choice for patients with end-stage renal diseases. Because of good long-term outcome, pediatric kidney grafts are also accepted for transplantation in adult recipients despite a significant mismatch in body size and age between donor and recipient. These grafts show a remarkable ability of adaptation to the recipient body and increase in size in a very short period, presumably as an adaptation to hyperfiltration. Methods. We investigated renal graft growth as well as glomerular proliferation and differentiation markers Kiel-67, paired box gene 2 and Wilms tumor protein (WT1 expression in control biopsies from different transplant constellations: infant donor for infant recipient, infant donor for child recipient, infant donor for adult recipient, child donor for child recipient, child donor for adult recipient, and adult donor for an adult recipient. Results. We detected a significant increase in kidney graft size after transplantation in all conditions with a body size mismatch, which was most prominent when an infant donated for a child. Podocyte WT1 expression was comparable in different transplant conditions, whereas a significant increase in WT1 expression could be detected in parietal epithelial cells, when a kidney graft from a child was transplanted into an adult. In kidney grafts that were relatively small for the recipients, we could detect reexpression of podocyte paired box gene 2. Moreover, the proliferation marker Kiel-67 was expressed in glomerular cells in grafts that increased in size after transplantation. Conclusions. Kidney grafts rapidly adapt to the recipient size after transplantation if they are transplanted in a body size mismatch constellation. The increase in transplant size is accompanied by an upregulation of proliferation and dedifferentiation markers in podocytes. The different examined conditions exclude hormonal factors as the key trigger for this growth so that

The studied shallow marine sediments are situated south and southwest of Jiroft town, 180 km south of Keman, from the Tihoiyeh section (near Tihoiyeh village). These deposits at the top of the section include marly limestones with index Nummulites species such as N. perforatus (De Montfort), N. lyelli (D'Archiac and Haime). According to Schaub's nummulitic time scale (1981) and shallow benthic zonation of Serra-Kiel et al. (1998), this interval referred to Bartonian age and SBZ17 zone, respectively. Also, the calcareous nannofossil study on this interval led to identification of 19 well-preserved species belonging to 11 genera of this plankton group. Based on determined index calcareous nannofossiltaxa such as Reticulofenestra bisecta, Sphenolithus obtusus, Sphenolithus intercalaris, Cribrocentrum erbae and associated species such as Sphenolithus pseudoradians, Reticulofenestra wadeae, Cribrocentrum reticulatum and Blackites spinosus this interval assigned to the CNE15 zone of Agnini et al. (2014) that corresponds to upper part of NP16 and lower part of NP17 zones of Martini (1971). It is resulted that, the detected shallow benthic foraminifera zone, corresponds to the calcareous nannofossil zones both indicating Bartonian age.

This is the final report for the project 'Correlations in Confined Quantum Plasmas', NSF-DOE Partnership Grant DE FG02 07ER54946, 8/1/2007 - 7/30/2010. The research was performed in collaboration with a group at Christian Albrechts University (CAU), Kiel, Germany. That collaboration, almost 15 years old, was formalized during the past four years under this NSF-DOE Partnership Grant to support graduate students at the two institutions and to facilitate frequent exchange visits. The research was focused on exploring the frontiers of charged particle physics evolving from new experimental access to unusual states associated with confinement. Particular attention was paid to combined effects of quantum mechanics and confinement. A suite of analytical and numerical tools tailored to the specific inquiry has been developed and employed

Comparing visualization techniques for learning second language prosody

Niebuhr, Oliver; Alm, Maria Helena; Schümchen, Nathalie

2017-01-01

We tested the usability of prosody visualization techniques for second language (L2) learners. Eighteen Danish learners realized target sentences in German based on different visualization techniques. The sentence realizations were annotated by means of the phonological Kiel Intonation Model...... and then analyzed in terms of (a) prosodic-pattern consistency and (b) correctness of the prosodic patterns. In addition, the participants rated the usability of the visualization techniques. The results from the phonological analysis converged with the usability ratings in showing that iconic techniques......, in particular the stylized “hat pattern” visualization, performed better than symbolic techniques, and that marking prosodic information beyond intonation can be more confusing than instructive. In discussing our findings, we also provide a description of the new Danish-German learner corpus we created: DANGER...

Primary non-Hodgkin's lymphoma occurs quite seldom in the nasopharynx, therefore reports on this topic are rare in medical literature. The treatment results of 30 irradiated patients (40 to 60 Gy) are presented. The period of the study ranges from 1960 to 1985. 13 patients with low grade lymphoma and 17 patients with high grade lymphoma according to the Kiel classification form the basis of this study. The overall actuarial 5-year survival rate is 24%. This also applies for the subgroups of low grade and high grade lymphomas with a 5-year survival rate of 24%, respectively. The evaluation of the patients without generalization in the course of disease shows that the prognosis of stage IE patients with 43% was superior to the one of stage IIE patients with 25% (p [de

Information on physiological rates and tolerances helps one gain a cause-and-effect understanding of the role that some environmental (bottom–up) factors play in regulating the seasonality and productivity of key species. We combined the results of laboratory experiments on reproductive success...... that included the effects of ‘controlling’, ‘masking’ and ‘directive’ environmental factors.

The potential use of mussel farms in German coastal waters as an option to improve water quality

DEFF Research Database (Denmark)

Friedland, René; Maar, Marie

Many German coastal waters like Szczecin (Oder) Lagoon or Bay of Greifswald are strongly used, heavily polluted by nutrients and at the same time a crucial supplier of ecosystem services. Although, nutrient loads have been decreased over the last decade, water quality of most coastal waters...... remained bad characterized by low macrophytes coverage and secchi depth caused by high phytoplankton densities and strong resuspension of sediments. Hence the Good Environmental Status claimed by EU`s Water Framework Directive will not be achieved in most coastal waters. Introducing mussel farming...... techniques is seen as an option to reduce the phytoplankton densities and to improve water transparency, e.g. in Kiel Bay a first farm using Mytilus edulis is running. Unfortunately, most German coastal waters have only low salinities causing a limited growth of Mytilus spp. or make it even impossible – like...

[Werner Catel--a protagonist in Nazi "pediatric euthanasia" and his post-war career].

Petersen, Hans-Christian; Zankel, Sönke

2003-01-01

This article deals with the biography of Werner Catel, a German paediatrician and protagonist of the Nazi programme for "euthanasia of children". Based on original research into recently discovered source materials, two aspects of Catel's life are considered. Firstly, Catel's attitude towards "euthanasia" is analysed. This analysis is not limited to the period of National Socialism, but focuses also on the phase before 1933 and especially on the era after 1945. Secondly, the authors explore Catel's academic career. What effects on his career in the later Federal Republic of Germany had his exposed role in the Nazi programme for "euthanasia of children"? In this context it is also examined how the Christian-Albrechts-University of Kiel/Germany, which employed Catel until 1960 in a leading position, judged the work of its former professor after his death.

2015-04-30

Dacryoconarids are extinct marine zooplankton known from abundant, globally distributed calcite microfossils in the Devonian, but their shell stable isotope composition has not been previously explored. Devonian stable isotope stratigraphy is currently limited to less common invertebrates or bulk rock analyses of uncertain provenance. As with Cenozoic planktonic foraminifera, isotopic analysis of dacryoconarid shells could facilitate higher-resolution, geographically widespread stable isotope records of paleoenvironmental change, including marine hypoxia events, climate changes, and biocrises. We explored the use of Dacryoconarid isotope stratigraphy as a viable method in interpreting paleoenvironments. We applied an established method for determining stable isotope ratios (δ(13) C, δ(18) O values) of small carbonate microfossils to very well-preserved dacryoconarid shells. We analyzed individual calcite shells representing five common genera using a Kiel carbonate device coupled to a MAT 253 isotope ratio mass spectrometer. Calcite shell δ(13) C and δ(18) O values were compared by taxonomic group, rock unit, and locality. Single dacryoconarid calcite shells are suitable for stable isotope analysis using a Kiel-IRMS setup. The dacryoconarid shell δ(13) C values (-4.7 to 2.3‰) and δ(18) O values (-10.3 to -4.8‰) were consistent across taxa, independent of shell size or part, but varied systematically through time. Lower fossil δ(18) O values were associated with warmer water temperature and more variable δ(13) C values were associated with major bioevents. Dacryoconarid δ(13) C and δ(18) O values differed from bulk rock carbonate values. Dacryoconarid individual microfossil δ(13) C and δ(18) O values are highly sensitive to paleoenvironmental changes, thus providing a promising avenue for stable isotope chemostratigraphy to better resolve regional to global paleoceanographic changes throughout the upper Silurian to the upper Devonian.

The primary objective of our study was to test the construct validity of the HystSim hysteroscopic simulator to determine whether simulation training can improve the acquisition of hysteroscopic skills regardless of the previous levels of experience of the participants. The secondary objective was to analyze the performance of a selected task, using specially designed scoring charts to help reduce the learning curve for both novices and experienced surgeons. The teaching of hysteroscopic intervention has received only scant attention, focusing mainly on the development of physical models and box simulators. This encouraged our working group to search for a suitable hysteroscopic simulator module and to test its validation. We decided to use the HystSim hysteroscopic simulator, which is one of the few such simulators that has already completed a validation process, with high ratings for both realism and training capacity. As a testing tool for our study, we selected the myoma resection task. We analyzed the results using the multimetric score system suggested by HystSim, allowing a more precise interpretation of the results. Between June 2014 and May 2015, our group collected data on 57 participants of minimally invasive surgical training courses at the Kiel School of Gynecological Endoscopy, Department of Gynecology and Obstetrics, University Hospitals Schleswig-Holstein, Campus Kiel. The novice group consisted of 42 medical students and residents with no prior experience in hysteroscopy, whereas the expert group consisted of 15 participants with more than 2 years of experience of advanced hysteroscopy operations. The overall results demonstrated that all participants attained significant improvements between their pretest and posttests, independent of their previous levels of experience (p hysteroscopic skills, proving an adequate construct validation of the HystSim. Using the multimetric scoring system enabled a more accurate analysis of the performance of the

The architecture of Kiel Data Management Infrastructure (KDMI) is setup to serve from the data creation process all the way to the data publication procedure. Accordingly the KDMI is managing data at the right beginning of the data life cycle and does not leave data unattended at this very crucial time. Starting from the chosen working procedure to handwritten protocols or lab notes the provenance of the resulting research data is captured within the KDMI. The provenance definition system is the fundamental (see figure 1) capturing tool for working procedures. The provenance definition is used to enable data input by file import, web client or hand writing recognition. The captured data in the provenance system for data is taking care of unpublished in house research data created directly on site. This system serves as a master for research data systems with more degrees of freedom in regard to technology, design or performance (e.g. GraphDB, etc). Such research systems can be regarded as compilations of unpublished data and public domain data e.g. from World Data Centers or archives. These compilations can be used to run statistical data mining and pattern finding algorithms on these specially designed platforms. The architecture of the KDMI ensures that a technical solution for data correction from the slave systems to the master system is possible and improves the quality of the stored data in the provenance system for data. After the research phase is over and the interpretation is finished the provenance system is used by a workflow based publication system called PubFlow. Within PubFlow it is possible to create repeatable workflows to publish data into various external long-term archives or World Data Center. The KDMI is based on the utilization of persistent identifiers for samples and person identities to support this automatized publication process. The publication process is the final step of the KDMI and the management responsibility of the long

2016-10-01

The energy loss of ions in solids is of key relevance for many applications of plasmas, ranging from plasma technology to fusion. Standard approaches are based on density functional theory or SRIM simulations, however, the applicability range and accuracy of these results are difficult to assess, in particular, for low energies. Here we present an independent approach that is based on ab initio nonequilibrium Green functions theory, e.g. that allows to incorporate electronic correlations effects of the solid. We present the first application of this method to low-temperature plasmas, concentrating on proton and alpha-particle stopping in a graphene layer. In addition to the stopping power we present time-dependent results for the local electron density, the spectral function and the photoemission spectrum that is directly accessible in optical, UV or x-ray diagnostics. http://www.itap.uni-kiel.de/theo-physik/bonitz/.

This article reports on the development of the cost effective abrasive cutting Sabre system which came as a result of UWG's work on the decommissioning of the Phillips' Maureen wells and adds to UWG's 'total severance solution' tools. The advantages of the system are highlighted and include the ability to operate from a platform or diving support vessel, to cut internal cases, and to eliminate the use of environmentally damaging explosives and the need to operate from a rig. The new Mark II version of the Sabre designed to work at greater depths of water, the range of the severance tools, UWG's well abandonment hole assembly system, and its aim to enter the Gulf of Mexico market are discussed. Details are given of the decommissioning of the Schwedeneck-See platforms in Kiel Bay off Germany and the Phillips' UK decommissioning plans for the Maureen platform

Theory of a spherical electrostatic probe in a continuum plasma: Analytical models

International Nuclear Information System (INIS)

Brailsford, A.D.

1977-01-01

A simple physical model of the charge distribution surrounding a biased spherical probe in a quiescent plasma, suggested by the theory of Su and Lam, is used to rederive the probe current-voltage characteristic. The result is compared with that of a slightly different version due to Kiel and with the exact numerical results of Baum and Chapkis. It is shown that if the ratio of the probe radius to the Debye length of the plasma is greater than or of the order of unity, the model calculation is in excellent agreement with the exact results when the dimensionless probe voltage phi/sup asterisk//sub p/,=vertical-barephi/sub p//kTvertical-bar in standard notation, is greater than 10, for both thick and thin sheaths. The comparison also provides an assessment of the importance of various additional validity criteria encountered in analytical treatments of the problem

The first centromeric protein identified in any species was CENP-A, a divergent member of the histone H3 family that was recognised by autoantibodies from patients with scleroderma-spectrum disease. It has recently been suggested to rename this protein CenH3. Here, we argue that the original name should be maintained both because it is the basis of a long established nomenclature for centromere proteins and because it avoids confusion due to the presence of canonical histone H3 at centromeres.

2013-09-01

Fast detectors employed at third-generation synchrotrons have reduced collection times significantly and require the optimization of commercial as well as customized software packages for data reduction and analysis. In this paper a procedure to collect, process and analyze single-crystal data sets collected at high pressure at the Extreme Conditions beamline (P02.2) at PETRA III, DESY, is presented. A new data image format called `Esperanto' is introduced that is supported by the commercial software package CrysAlis(Pro) (Agilent Technologies UK Ltd). The new format acts as a vehicle to transform the most common area-detector data formats via a translator software. Such a conversion tool has been developed and converts tiff data collected on a Perkin Elmer detector, as well as data collected on a MAR345/555, to be imported into the CrysAlis(Pro) software. In order to demonstrate the validity of the new approach, a complete structure refinement of boron-mullite (Al5BO9) collected at a pressure of 19.4 (2) GPa is presented. Details pertaining to the data collections and refinements of B-mullite are presented.

Bluff-body drag reduction using a deflector

Science.gov (United States)

Fourrié, Grégoire; Keirsbulck, Laurent; Labraga, Larbi; Gilliéron, Patrick

2011-02-01

A passive flow control on a generic car model was experimentally studied. This control consists of a deflector placed on the upper edge of the model rear window. The study was carried out in a wind tunnel at Reynolds numbers based on the model height of 3.1 × 105 and 7.7 × 105. The flow was investigated via standard and stereoscopic particle image velocimetry, Kiel pressure probes and surface flow visualization. The aerodynamic drag was measured using an external balance and calculated using a wake survey method. Drag reductions up to 9% were obtained depending on the deflector angle. The deflector increases the separated region on the rear window. The results show that when this separated region is wide enough, it disrupts the development of the counter-rotating longitudinal vortices appearing on the lateral edges of the rear window. The current study suggests that flow control on such geometries should consider all the flow structures that contribute to the model wake flow.

The concentrations and deposition of atmospheric trace substances were measured over the Kiel Bight and the Southern North Sea. A European longrange-transport model was used to calculate the atmospheric concentrations of trace metals and their deposition into the North Sea and the Baltic Sea. Natural and anthropogenic emitted element concentrations could be separated definitely by the measurements, and preferred transport directions of anthropogenic contributions could be found. Concentrations measured over the North Sea could be related to the surrounding emission areas by airmass trajectory analyses. The deposition measurements show that the main removal process is due to deposition by precipitation. Calculated and measured concentrations at several receptor points agreed well. The model results confirm the dominating role of wet deposition. It could be shown that extrapolations from measurements at coastal stations to the whole sea area tend to overestimate the total deposition into North Sea and Baltic Sea. (orig.)

Sy, A

1983-01-01

This report reviews CTD data handling and the principle of processing for the profiling instrument 'Multisonde' as it is presently in use at the Institut fuer Meereskunde in Kiel, F.R.G., in the frame of the research programme 'Warmwassersphaere'. An introduction to the shipboard system of measuring and logging is given. An outline of both laboratory and in situ calibrations is presented. The main subject of this report is the processing of the data. Possible sources of errors in field measurements and their influence on data accuracy are discussed and the standard processing stages are described. A specific problem lies in data errors, which inhibit a routine processing. In order to edit these data a special filter, the median filter, is introduced. Its efficiency as well as the experiences gained through its practical application is described and discussed by means of comparison with conventional techniques. The data used for these tests were collected during the experiment Nordostatlantik '81.

Microbial adherence to dental implant surfaces is one initiating step in the formation of plaque and is considered to be an important event in the pathogenesis of peri-implant disease. Besides good connective tissue adhesion in the transmucosal part of an implant, titanium implants exposed to the oral cavity require surface modification to inhibit the adherence of oral bacteria. Surface roughness and chemical composition of the implant surface were found to have a significant impact on plaque formation. The aim of the present study was to examine bacterial adherence of differently modified potential implant surfaces. Therefore the surface roughness was decreased and for example a thin ceramic or composite layer of antibacterial material was deposited on abutment surface by sputtering. We analyze the new surface with AFM to control the roughness. For further characterization contact angle measurements were carried out. Biocompatibility and antibacterial effects will be determined in cooperation with the dental clinic at the University Kiel.

A multimodel comparison of centennial Atlantic meridional overturning circulation variability

A mechanism contributing to centennial variability of the Atlantic Meridional Overturning Circulation (AMOC) is tested with multi-millennial control simulations of several coupled general circulation models (CGCMs). These are a substantially extended integration of the 3rd Hadley Centre Coupled Climate Model (HadCM3), the Kiel Climate Model (KCM), and the Max Plank Institute Earth System Model (MPI-ESM). Significant AMOC variability on time scales of around 100 years is simulated in these models. The centennial mechanism links changes in the strength of the AMOC with oceanic salinities and surface temperatures, and atmospheric phenomena such as the Intertropical Convergence Zone (ITCZ). 2 of the 3 models reproduce all aspects of the mechanism, with the third (MPI-ESM) reproducing most of them. A comparison with a high resolution paleo-proxy for Sea Surface Temperatures (SSTs) north of Iceland over the last 4,000 years, also linked to the ITCZ, suggests that elements of this mechanism may also be detectable in the real world.

Study of the ion density of a radio-frequency plasma using electrostatic probes and focussed microwave interferometers

International Nuclear Information System (INIS)

Nguyen Cao, L.; Gagne, R.R.J.

1976-01-01

In order to verify experimentally and compare recent ion theories for cylindrical electrostatic probes, the ion density in a radio-frequency plasma was evaluated from V-I curves by means of six different theories. At low pressures, the theories of Bernstein and Rabinowitz, of Lam and Laframboise, give values of density which differ respectively by 20, 25 and 30% compared with the values obtained using a 10GHz focussed microwave interferometer. At the continuum limit, The Schulz and Brown's, and Su and Kiel's theories give density values which disagree respectively by 55 and 20%, compared with the values obtained by microwaves. For pressures varying from 0.05 to 3mmHg, the decrease of ion current, as predicted theorically by Waymouth, was observed. The density perturbation near the probe was found to be a dominant factor affecting the precision of density measurements, for pressures up to 2mmHg at least for our experimental conditions [fr

The necessary amount of work increases dramatically with the size of systems, so one has to search for algorithms that most efficiently and accurately solve systems of, e.g., several million equations. The choice of algorithms depends on the special properties the matrices in practice have. An important class of large systems arises from the discretization of partial differential equations. In this case, the matrices are sparse (i.e., they contain mostly zeroes) and well-suited to iterative algorithms. The first edition of this book grew out of a series of lectures given by the author at the Christian-Albrecht University of Kiel to students of mathematics. The second edition includes quite novel approaches.

Abundance and biomass data for juveniles and adults, length frequency histograms and the electron microprobe analysis (EPMA) of otoliths were used to indicate density, migration and reproduction of common bream Abramis brama in the Kiel Canal drainage, Germany. The reproduction of common bream was primarily restricted to two types of spawning habitats: one in the Haaler Au, a freshwater tributary and another in shallow, oligohaline portion of the main Canal. Both spawning habitats were morphologically characterized as shallow with submerged vegetation. During April to June concentrations of spawners were observed, whereas age-0 common bream dominated from August through December. The distribution of age-0 common bream was primarily restricted to fresh and oligohaline waters. Outside the spawning season, the distribution of common bream was less obvious. Adult fish were more widely distributed within the Canal, indicating a tolerance for higher salinities. During the spawning season common bream seem to show an exceptional mobility between spawning and feeding habitats, which are denoted by different salinities.

Full Text Available The Economic Actions in Education training module (EAE teaches how to handle, use and judge external standardized tests in schools. The EAE programme was implemented in teacher training at the University of Kiel, because teachers are increasingly under external scrutiny and are being held accountable for student and school achievements. The EAE programme includes a reader (in English, through which prospective teachers understand and analyze core terms of the field. Furthermore, different didactical methods such as think-pair-share, role play and short lectures provide a group dynamic in which students gain an insight into standardized tests at a macro level. Students learn what is involved in standardized tests and they develop the ability to make a critical judgement about how they will use or refuse standardized tests in schools. EAE enables teachers to use standardized tests for curriculum and instruction improvement as well as refuse standardized tests to highlight autonomous teaching and decline governance from outside.

1983-01-01

The data of the annual variation of cosmic ray intensity measured by neutron detectors were used to study the distribution of cosmic ray intensity vertical to the solar equator plane and its long term variation. The data used were obtained at Deep River, Kiel, Kerguelen Island, McMurdo, Ottawa, and Mt. Washington. All data showed annual variation. The patterns and degree of variation obtained in northern and southern hemisphere were similar. The summation dial representation of the annual variation and semi-annual variation of cosmic ray was obtained. The inversion of annual variation in 1958 - 1959 and 1968 - 1969 corresponded to the inversion of polarity of solar pole magnetic field. The semi-annual variation showed a complex behavior. The helio-latitudial distribution of cosmic ray intensity was obtained. The asymmetric distribution in relation to the solar equator was observed in the annual variation. The northward gradient of density in 1955 - 1958 and southward gradient in 1959 - 1968 were seen. (Kato, T.)

Long-term trends at the Boknis Eck time series station (Baltic Sea, 1957–2013: does climate change counteract the decline in eutrophication?

Full Text Available The Boknis Eck (BE time series station, initiated in 1957, is one of the longest-operated time series stations worldwide. We present the first statistical evaluation of a data set of nine physical, chemical and biological parameters in the period of 1957–2013. In the past three to five decades, all of the measured parameters underwent significant long-term changes. Most striking is an ongoing decline in bottom water oxygen concentration, despite a significant decrease of nutrient and chlorophyll a concentrations. Temperature-enhanced oxygen consumption in the bottom water and a prolongation of the stratification period are discussed as possible reasons for the ongoing oxygen decline despite declining eutrophication. Observations at the BE station were compared with model output of the Kiel Baltic Sea Ice Ocean Model (BSIOM. Reproduced trends were in good agreement with observed trends for temperature and oxygen, but generally the oxygen concentration at the bottom has been overestimated.

Attorneys for the Ocean - Graduate Training in the Transatlantic Helmholtz Research School for Ocean System Science and Technology (HOSST/TOSST)

The worldwide growth in population and standards of living is leading to ever increasing human pressure on the oceans: as a source of resources, a transportation/trade pathway, and a sink for pollutants. However, use of the world's ocean is not presently guided by any over-arching management plan at either national or international level. Marine science and technology provide the necessary foundation, both in terms of system understanding and observational and modeling tools, to address these issues and to ensure that management of ocean activities can be placed on the best-possible scientific footing. The transatlantic Helmholtz Research School Ocean Science and Technology pools the complementary expertise of the Helmholtz Centre for Ocean Research Kiel (GEOMAR), the Christian-Albrechts-Universität zu Kiel, Dalhousie University and the Institute for Ocean Research Enterprise (IORE), to train the next generation of researchers in the key scientific areas critical for responsible resource utilization and management of the ocean with special emphasis on our "local ocean" - the North Atlantic. The Research School is organized around three themes which encompass key sensitivities of the North Atlantic to external forcing and resource exploitation: 4D Ocean Dynamics, Ecosystem Hotspots, and Seafloor Structures. Interactions within and between these themes regulate how the ocean system responds to both anthropogenic and natural change. The HOSST/TOSST fellows gain an in-depth understanding of how these ocean systems interact, which in turn provides a solid understanding for the formulation of scientifically-sound management practices. Given the broad scope of the school, student education is two-pronged: it provides excellent institutional support where needed, including scientific input, personal support and financial incentives, while simultaneously generating an open "intellectual space" in which ingenious, often unpredictable, ideas can take root, overcoming

Seagrass beds as ocean acidification refuges for mussels? High resolution measurements of pCO2 and O2 in a Zostera marina and Mytilus edulis mosaic habitat

Science.gov (United States)

It has been speculated that macrophytes beds might act as a refuge for calcifiers from ocean acidification. In the shallow nearshores of the western Kiel Bay (Baltic Sea), mussel and seagrass beds are interlacing, forming a mosaic habitat. Naturally, the diverse physiological activities of seagrasses and mussels are affected by seawater carbonate chemistry and they locally modify it in return. Calcification by shellfishes is sensitive to seawater acidity; therefore the photosynthetic activity of seagrasses in confined shallow waters creates favorable chemical conditions to calcification at daytime but turn the habitat less favorable or even corrosive to shells at night. In contrast, mussel respiration releases CO2, turning the environment more favorable for photosynthesis by adjacent seagrasses. At the end of summer, these dynamics are altered by the invasion of high pCO2/low O2 coming from the deep water of the Bay. However, it is in summer that mussel spats settle on the leaves of seagrasses until migrating to the permanent habitat where they will grow adult. These early life phases (larvae/spats) are considered as most sensitive with regard to seawater acidity. So far, the dynamics of CO2 have never been continuously measured during this key period of the year, mostly due to the technological limitations. In this project we used a combination of state-of-the-art technologies and discrete sampling to obtain high-resolution time-series of pCO2 and O2 at the interface between a seagrass and a mussel patch in Kiel Bay in August and September 2013. From these, we derive the entire carbonate chemistry using statistical models. We found the monthly average pCO2 more than 50 % (approx. 640 μatm for August and September) above atmospheric equilibrium right above the mussel patch together with large diel variations of pCO2 within 24 h: 887 ± 331 μatm in August and 742 ± 281 μatm in September (mean ± SD). We observed important daily corrosiveness for calcium

The Holy Grail of outer space: pluralism, Druidry, and the religion of cinema in The Sky Ship.

Science.gov (United States)

Bjørnvig, Thore

2012-10-01

The Danish silent movie Himmelskibet (in English, A Trip to Mars or The Sky Ship) premiered in 1918, and a novelization of the movie appeared in 1921. The film is about a trip to Mars and portrays a Martian civilization that embraces a life of peace, vegetarianism, and non-alcoholism. Both movie and novel, though especially the novel, provide insight into the plurality-of-worlds debate in Denmark in the early 20(th) century, forming as it did a part of a general debate about the relationship between science and religion. Yet The Sky Ship did not only form part of this debate but also displayed strong religious currents itself. Most notably, a romantic, Neo-Platonically inspired Christian version of Druidry informed the portrayal of the Martians and their society. Finally, the medium itself played a role in the story. By transcending language barriers, silent movies were imagined by some to be a kind of "Esperanto of the eye" that would usher in a new golden age for mankind, even contributing to ending the horrors of World War I. Thus, The Sky Ship offers insight into an intriguing conglomeration of pluralism, religion, and technology that should be of interest to historians of astrobiology.

A passive flow control on a generic car model was experimentally studied. This control consists of a deflector placed on the upper edge of the model rear window. The study was carried out in a wind tunnel at Reynolds numbers based on the model height of 3.1 x 10{sup 5} and 7.7 x 10{sup 5}. The flow was investigated via standard and stereoscopic particle image velocimetry, Kiel pressure probes and surface flow visualization. The aerodynamic drag was measured using an external balance and calculated using a wake survey method. Drag reductions up to 9% were obtained depending on the deflector angle. The deflector increases the separated region on the rear window. The results show that when this separated region is wide enough, it disrupts the development of the counter-rotating longitudinal vortices appearing on the lateral edges of the rear window. The current study suggests that flow control on such geometries should consider all the flow structures that contribute to the model wake flow. (orig.)

Since measurements of space probes in the interplanetary space became available it has been known that associated with the occurrence of recurrent fast and slow solar wind streams, forming Corotating Interaction Regions, recurrent variations in the cosmic ray nuclei flux are observed. As pointed out recently by Jokipii and Kota (2) recurrent modulation for positively and negatively charged particles may be different. In the time interval extending from July 1992 to July 1994, Ulysses on its journey to high heliographic latitudes registered ∼20 stable and long-lasting Corotating Interaction Regions (CIRs). In this work we use data from the Cosmic Ray and Solar Particle Investigation Kiel Electron Telescope (COSPIN/KET) instrument on board Ulysses to study the recurrent variation of 2.5 GV electrons and protons. We find that 1) electrons are indeed periodically modulated, but that 2) the periodicity of ∼29 days is longer than the period of ∼26 days for protons, and that 3) the amplitude is larger than the one observed for protons

Full Text Available In context of the first study on folk linguistic concepts in the German language area carried out by the Kiel DFG research project "perceptual dialectology", this article looks at how salient features could be surveyed and categorized by a stimulus-response-test. After a definition of salience, the study design including the stimulus-response-test is presented. The test was created and modified during the project as a guessing game by the Institute for German Language (IDS Mannheim. The central question in this article is which linguistic features stimulate the informants to locate a speech sample on a map with predetermined cities and hence which salient features trigger the regional identification. In a second step, the speech samples are analyzed by the variables 'pleasantness' and 'correctness' defined by Dennis R. Preston. The central question here is: Are speech samples with a high pleasure value also automatically considered correct? Finally, an interpretation of metalinguistic comments in the speech examples will give more insight into folk linguistic concepts and the role of salient features in this regard.

207 clinical isolates from strains of patients from the University Children's Hospital of Kiel were investigated for their in vitro activity with the agar dilution method against flomoxef and cefazolin (alone and partially in combination with vancomycin). Staphylococci were also tested with other cephalosporins (cefoxitin, cefamandole, cefotaxime, cefotetan and latamoxef). Flomoxef and cefazolin always acted more vigorously on staphylococci than the other cephalosporins. Resistance of Staphylococcus aureus strains against flomoxef and cefazolin did not occur but was found in 15 and 5 of 98 Staphylococcus epidermidis strains, respectively. Enterococcus faecalis strains were always resistant against both drugs; Streptococcus faecium strains were only moderately sensitive. Combined testing of flomoxef or cefazolin with vancomycin showed synergism in almost all staphylococcal strains. Synergism was stronger when S. epidermidis strains were only weakly sensitive to or resistant against flomoxef and cefazolin in comparison to highly sensitive strains. Flomoxef (or cefazolin) acted synergistically in combination with vancomycin on E. faecalis and S. faecium with the exception of two strains of E. faecalis which showed an additive effect of both drugs.

In proteomes of higher eukaryotes, many alternative splice variants can only be detected by their shared peptides. This makes it highly challenging to use peptide-centric mass spectrometry to distinguish and to quantify protein isoforms resulting from alternative splicing events. We have developed two complementary algorithms based on linear mathematical models to efficiently compute a minimal set of shared and unique peptides needed to quantify a set of isoforms and splice variants. Further, we developed a statistical method to estimate the splice variant abundances based on stable isotope labeled peptide quantities. The algorithms and databases are integrated in a web-based tool, and we have experimentally tested the limits of our quantification method using spiked proteins and cell extracts. The TAPAS server is available at URL http://davinci.crg.es/tapas/. luis.serrano@crg.eu or christina.kiel@crg.eu Supplementary data are available at Bioinformatics online. © The Author 2014.

System integration was developed for fuel cell to control various parameters including voltage, current, power, temperature, pressure of gas (H/sub 2/), humidification, etc. The compact software has also been developed for monitoring different parameters of fuel cell system. System integrated was installed on fuel cell stack to manipulate these parameters. The compact software has been linked with the integrated system for visual monitoring of different parameters of fuel cell system during operation on PC. The installation of software and integrated system on fuel cell stack is the key achievement for the safe operation of fuel cell stack and for the provision of requisite power to any electric device for optimum performance. The compact software was developed for micro controller in KIEL. Control card and driver card are controlled by software-driven micro controller. A communication protocol was designed and developed. PC software has been developed to control and watch the values of all parameters of fuel cell such as voltage, current, power, temperature, pressure of hydrogen, pressure of oxygen, operational times and performance of the system on computer screen.

Ion-Flow-Induced Excitation of Electrostatic Cyclotron Mode in Magnetized Dusty Plasma

Science.gov (United States)

Bezbaruah, P.; Das, N.

2018-05-01

The stability of electrostatic cyclotron mode is investigated in a flowing magnetized dusty plasma in the presence of strong ion-neutral collisions. In the high magnetic field limit, when the dust magnetization becomes important, it is expected that the collective behavior of magnetized dust grains suspended in the near-sheath region substantially influences the dispersion properties of electrostatic modes. The growth/damping of the collective excitation is significantly controlled by such parameters as the ion-neutral collision frequency, Mach number, and magnetic field strength. In our case, the explicit dependence of the Mach number on the magnetic field and collision frequency has been taken into account and possible implications on the stability of the mode is analyzed. Streaming instability of cyclotron modes may be important to understand issues related to the interaction mechanism between dust grains and other associated phenomena like Coulomb crystallization, phase behavior, transport properties, etc., in the relatively strong magnetic field limit, which is currently accessible in the DPD (Kiel University) and MDPX (PSL, Auburn University) experiments.

Influence of the terrestrial magnetic field geometry on the cutoff rigidity of cosmic ray particles

International Nuclear Information System (INIS)

Herbst, K.; Kopp, A.; Heber, B.

2013-01-01

Studies of the propagation of charged energetic particles in the Earth's magnetic field go back to Carl Stoermer. In the end, his investigations finally lead to the definition of the so-called cutoff rigidity RC; that is, the minimum momentum per charge a particle must have in order to reach a certain geographical location. Employing Monte Carlo simulations with the PLANETOCOSMICS code we investigate the correlation between the geomagnetic field structure and the cutoff rigidity. We show that the geometry of the magnetic field has a considerable influence on the resulting cutoff rigidity distribution. Furthermore, we will present a simple geometry-based parameter, δB, which is able to reflect the location-dependent cutoff rigidity. We show that this correlation is also visible in the temporal evolution of the Earth's magnetic field, at least over the last 100 yr. Using latitude scans with neutron monitors, changes of the relative counting rates at different positions are calculated, showing small variations for, e.g., Kiel and Moscow, while large ones occur at Mexico City as well as on the British Virgin Islands.

A complex nozzle concept, which fuses multiple canonical flows together, has been experimentally investigated via pressure, schlieren and PIV in the anechoic chamber at Syracuse University. Motivated by future engine designs of high-performance aircraft, the rectangular, supersonic jet under investigation has a single plane of symmetry, an additional shear layer (referred to as a wall jet) and an aft deck representative of airframe integration. Operating near a Reynolds number of 3 ×106 , the nozzle architecture creates an intricate flow field comprised of high turbulence levels, shocks, shear & boundary layers, and powerful corner vortices. Current data suggest that the wall jet, which is an order of magnitude less energetic than the core, has significant control authority over the acoustic power through some non-linear process. As sound is a direct product of turbulence, experimental and analytical efforts further explore this interesting phenomenon associated with the turbulent flow. The authors acknowledge the funding source, a SBIR Phase II project with Spectral Energies, LLC. and AFRL turbine engine branch under the direction of Dr. Barry Kiel.

Microfacies analysis of foraminifera rich sedimentary rocks from the Desert Plateau, central Egypt.

Microfacies analysis on some samples from the Thebes Group have been carried on by means of thin sections. The study area is included in the Libyan Desert Plateau (central Egypt) at following coordinates N27° 36'30.58" E29° 44'58.34", near the biggest dune of Egypt, the Ghard Abu Muharik. Because of the round shape of the rocks and the desert patina on the surface they could easily be classified as the so called "Melonstones", which are located more southwards and mainly composed by stromatolites. On the contrary, the investigated samples show a completely different fauna and therefore have been separated from the "Melonstones". Even if shape and size are very similar and the desert patina covers all surfaces the same way the differences are impressive. To investigate the samples, two thin-sections have been prepared and analyzed at the microscope. The observed fauna is composed by: agglutinated benthic foraminifera (e.g., Dictyoconus egypticus), complex larger miliolids (e.g., Pseudolacazina cf. danatae, Fabularia sp.), alveolinids (Alveolina vredenburgi), green algae (Dasycladaceae), echinoids and corals. Because of the presence of symbionts bearing larger benthic foraminifera, which need light to feed photosymbionts, the rock was formed in a shallow water environment. With the abundant rock-building benthic foraminifera and calcareous algae the limestone shows a tendency to the packstone/wackestone facies. Based on the presence of Alveolina vredenburgi, the age of the samples can be estimate as lowermost Eocene belonging to the shallow benthic zone 5 (sensu Serra-Kiel et al., 1998). According the obtained data on stratigraphy and palaeoecology, a partial palaeoenvironmental reconstruction is possible for the Libyan Desert Plateau where outcrops are largely missing. Because of the round shape of the samples and the patina which covers them all around it can be assumed that they have been transported from longer distance. According to the geological map of the

Derivation of muon range spectrum under rock from the recent primary spectrum

International Nuclear Information System (INIS)

Pal, P.; Bhattacharyya, D.P.

1985-01-01

The muon range spectra under Mont Blanc Tunnel and Kolar Gold Field rocks have been calculated from the recently measured primary cosmic ray spectrum. The scaling hypothesis of Feynman has been used for the calculation of pion and kaon spectra in the atmosphere. The meson atmospheric diffusion equation has been solved by following the method of Bugaev et al. The derived muon energy spectrum has been found to be in good agreement with the measured data of the Kiel, Durham, DEIS, and Moscow University groups. The calculated muon energy spectra at large polar angles have been compared with the different experimental results. The integral muon spectrum up to 20 TeV supports the MARS burst data favourably. Using the procedure of Kobayakawa, the muon energy loss in rock due to ionization, pair production, and bremsstrahlung and nuclear interactions from Bezrukov and Bugaev, we have constructed the range-energy relation in Mont Blanc and Kolar Gold Field rocks. The estimated range spectra have been corrected for range fluctuations and have been compared with the Mont Blanc Tunnel data of Castagnoli et al., Bergamasco et al., and Sheldon et al. and the Kolar Gold Field data compilation by Krishnaswamy et al

Verbal random number generation is a procedurally simple task to assess executive function and appears ideally suited for the use under diverse settings in cross-cultural research. The objective of this study was to examine ethnic group differences between young adults in Bali (Indonesia) and Kiel (Germany): 50 bilingual healthy students, 30 Balinese and 20 Germans, attempted to generate a random sequence of the digits 1 to 9. In Balinese participants, randomization was done in Balinese (native language L1) and Indonesian (first foreign language L2), in German subjects in the German (L1) and English (L2) languages. 10 of 30 Balinese (33%), but no Germans, were unable to inhibit habitual counting in more than half of the responses. The Balinese produced significantly more nonrandom responses than the Germans with higher rates of counting and significantly less occurrence of the digits 2 and 3 in L1 compared with L2. Repetition and cycling behavior did not differ between the four languages. The findings highlight the importance of taking into account culture-bound psychosocial factors for Balinese individuals when administering and interpreting a random number generation test.

Full Text Available Wolfgang M Thaiss1, Cornelius C Thaiss2, Christoph A Thaiss31Christian-Albrechts-Universty, Kiel, 2Ludwig-Maximilians-University, Munich, Germany; 3Yale University School of Medicine, New Haven, CT, USAAbstract: Tuberculosis is an ancient human disease that is still a major cause of death and one of the most challenging public health problems worldwide. After decades of stagnancy, new public–private partnerships to fight the disease and the increasing awareness of a vicious circle between the tuberculosis epidemic and the obstruction of economic development have fuelled recent progress in our understanding of the disease. As a result, new strategies to improve management and treatment of tuberculosis have been initiated. At the same time, however, the devastating effect of human immunodeficiency virus on tuberculosis susceptibility and the rapid expansion of multidrug-resistant (MDR tuberculosis threaten to undermine the advances made by tuberculosis management programs. With an estimated 9 million new cases annually, tuberculosis affects a higher number of individuals worldwide than ever before. Here, recent developments in the epidemiology and management of tuberculosis are summarized and an overview is provided of emerging strategies to combat this ancient scourge.Keywords: tuberculosis, epidemiology, management, multidrug resistance, vaccine

Full Text Available Several recent studies have revealed the impacts of the climate variability in the dynamic of zooplankton in different estuarine ecosystems, imposing a need for more and continued global studies. Presently, there is a growing appreciation in international collaborations to compare and contrast estuarine ecosystem response to climate variability across geographical gradients, including long-term changes in zooplankton. We performed a meta-analysis comprising field data from 7 location (Mondego estuary-Portugal, Seine estuary- France, Sheldt estuary- Belgium, Kiel fjord - Germany, Gulf of Riga- Latvia, Gulf of Bothnia – Sweden and Finland Archipelagos. The use of climatic modes (e.g. NAO, ENSO has proven useful in investigating links between climatic variations and ecological patterns. Therefore, the main focus will be to test the influence of the NAO on abundance of organisms, key species, local environment and whether these relationships are generally positive, whether they are sensitive to methodological differences among studies, between taxonomic group and key species. The knowledge gained will contribute to quantitatively evaluate the multi-scale structure of climate and marine environment and to identify a set of environmental indicators to assess the estuarine ecosystem state and risks for ecological shifts.

Central nervous system complications in non-Hodgkin-lymphomas and radiotherapy

1981-01-01

261 case historys of malignant non-Hodgkin-lymphomas were analysed in the years from 1969 until 1978 in the 'Radiologische Universitaetsklinik Kiel'/West-Germany. 18 Patients got a central nervous complication of Non Hodgkin-Lymphoma earlier or later, a percentage of about 7. There were 7 cases of lymphoblastic lymphoma (LB), a percentage of 10 for this entity. In the group of immunoblastic lymphoma (IB) 6 cases of central nervous infiltration were detected, that is a ratio of 7.7 percent. 4 case histories M. Brill-Symmers (CC/CB) were complicated by central nervous dissemination, a percentage of 5.3. Patients with lymphoblastic lymphoma have the highest risk of central nervous complication. The beginning of central nervous dissemination in the single case histories is very different between the histological groups. Patients with lymphoblastic lymphoma suffered from central nervous complication in an early phase of history, in cases of M. Brill-Symmers central nervous infiltration can occur also in a late phase. The results may determine the discussion about stratifying of radiotherapy. Early radiotherapy including central nervous system may be discussed and investigated in special histological entities of malignant non-Hodgkin-lymphoma. (orig.) [de

Generation of two-dimensional binary mixtures in complex plasmas

2016-10-01

Complex plasmas are an excellent model system for strong coupling phenomena. Under certain conditions the dust particles immersed into the plasma form crystals which can be analyzed in terms of structure and dynamics. Previous experiments focussed mostly on monodisperse particle systems whereas dusty plasmas in nature and technology are polydisperse. Thus, a first and important step towards experiments in polydisperse systems are binary mixtures. Recent experiments on binary mixtures under microgravity conditions observed a phase separation of particle species with different radii even for small size disparities. This contradicts several numerical studies of 2D binary mixtures. Therefore, dedicated experiments are required to gain more insight into the physics of polydisperse systems. In this contribution first ground based experiments on two-dimensional binary mixtures are presented. Particular attention is paid to the requirements for the generation of such systems which involve the consideration of the temporal evolution of the particle properties. Furthermore, the structure of these two-component crystals is analyzed and compared to simulations. This work was supported by the Deutsche Forschungsgemeinschaft DFG in the framework of the SFB TR24 Greifswald Kiel, Project A3b.

Poloidal shear flows play an important role in the improvement of plasma confinement in fusion devices. They limit the radial correlation length via the shear decorrelation mechanism [1] and can trigger transitions into transport barriers. External biasing can be used to drive poloidal shear flows [2] in order to study the decorrelation mechanism. The torsatron TJ-K is operated with low-temperature plasmas produced by ECRH. Coherent and quasi-coherent structures have been observed [3]. Their structure size varies according to the drift scale ρ_s. The influence of biasing on these structures is investigated by means of electrostatic probes. Electron density fluctuations as well as fluctuations of the floating potential tend to decrease in the presence of a positively biased probe. The evolution of radial electric field, poloidal flow and radial transport are investigated for different plasma parameters using a 2D Langmuir probe array with 64 tips in comparison with two-point correlation measurements. First results are presented. [1] H. Biglari et al., Phys. Fluids B 2, p. 1 (1990); [2] R. J. Taylor et al., Phys. Rev. Lett. 63, 21, p. 2365 (1989); [3] C. Lechte, PhD-Thesis, CAU Kiel (2003)

We present the first results of an accelerator mass spectrometry (AMS) radiocarbon intercomparison program on 3 different charcoal samples collected in one of the hearths of the Megaceros gallery of Chauvet Cave (Ardeche, France). This cave, rich in parietal decoration, is important for the study of the appearance and evolution of prehistoric art because certain drawings have been 14 C dated to the Aurignacian period at the beginning of the Upper Paleolithic. The new dates indicate an age of about 32,000 BP, which is consistent with this attribution and in agreement with the results from the same sector of the cave measured previously at the Laboratoire des Sciences du Climat et de l'Environnement (LSCE). Six laboratories were involved in the intercomparison. Samples were measured in 4 AMS facilities: Center for Isotope Research, Groningen University, the Netherlands; the Oxford Radiocarbon Accelerator Unit, UK; the Centre de datation par le carbone 14, Univ. Claude Bernard Lyon 1, France (measured by AMS facilities of Poznan University, Poland); and the LSCE, UMR CEA-CNRS-UVSQ, France (measured by the Leibniz-Labor of Christian-Albrechts-Universitat Kiel, Germany).

Mari JJ, Patel V, Kieling C, Razzouk D, Tyrer P, Herrman H. The 5/95 gap in the indexation of psychiatric journals of low- and middle-income countries. Objective: To investigate the relationship between science production and the indexation level of low- and middle-income countries (LAMIC) journals in international databases. Method: Indicators of productivity in research were based on the number of articles produced over the 1994–2004 period. A survey in both Medline and ISI/Thomson was conducted to identify journals according to their country of origin. A WPA Task Force designed a collaborative process to assess distribution and quality of non-indexed LAMIC journals. Results: Twenty LAMIC were found to present more than 100 publications and a total of 222 indexed psychiatric journals were found, but only nine were from LAMIC. The Task Force received 26 questionnaires from editors of non-indexed journals, and concluded that five journals would meet criteria for indexation. Conclusion: Barriers to indexation of journals contribute to the difficulties in achieving fair representation in the main literature databases for the scientific production in these countries.

Full Text Available The interest in intelligence construct operationalization is reflected in construction upon new intelligence concepts analyzing it in a wider social context. This scientific study offers the theoretical and empirical analysis of a newly created construct of moral intelligence. Moral intelligence concept was founded in the Multiple Intelligence Theory of H. Gardner (1985, being followed by L. Kuckovsky, A. Dobrin, V. Di Norcia and others in historical-philosophical-evolution-theological context, by D. Lennick, F. Kiel, C. Veach and others in successful management context and by A. Hass, M. Borba, R. Coles, J. Bradshaw and others in school-counselling context. Subsequently moral intelligence is defined as an individual's ability to solve ethical problems ethically right. The application of ethical principles in successful business management formed a theoretical base for moral intelligence characterized by D. Lennick a F. Kiel (2008. They created also a self-report questionnaire Moral Competence Inventory (MCI to assess personal moral competences as a base of moral intelligence. The study provides the results of psychometrical properties (factor structure and reliability in the sense of inner consistency and test-retest result stability of the Slovak, the only available, questionnaire for moral intelligence assessment at a chosen adolescent research sample (N=209.

Full Text Available In the half-century before the Great War, collaborative international ventures in science became increasingly common. The trend, manifested in scientific congresses and attempts to establish agreement on physical units and systems of nomenclature, had important consequences. One was the fear of information overload. How were scientists to keep abreast of the growing volume of books, journals, and reports? How were they to do so in an era without a common language? Responses to these challenges helped to foster new departures in cataloguing, bibliography, and an interest in Esperanto and other constructed languages. By 1914, the responses had also become involved in wider movements that promoted communication as a force for peace. The Great War dealt a severe blow to these cosmopolitan ideals, and the post-war reordering of international science did little to resurrect them. A “national turn” during the 1920s assumed a darker form in the 1930s, as totalitarian regimes in the Soviet Union, Italy, Germany, and Spain associated science ever more closely with national interests. Although the Second World War further undermined the ideal of internationalism in science, the vision of science as part of a world culture open to all soon resurfaced, notably in UNESCO. As an aspiration, it remains with us today, in ventures for universal access to information made possible by digitization and the World Wide Web. The challenge in the twenty-first century is how best to turn aspiration into reality.

Investigation and evaluation of airborne pollution in the framework of PARCOM (North Sea) and HELCOM (Baltic Sea) - subproject: Measurements of trace metals

International Nuclear Information System (INIS)

Schneider, B.

1993-01-01

On the basis of measurements of the deposition and concentrations of atmospheric trace metals the annual input of some selected elements (Pb, Zn, Cd, Ni, V) into the North Sea and the Baltic Sea was estimated. For the Baltic Sea, deposition measurements with a buoy system in the Kiel Bight and data from the EGAP(HELCOM)-monitoring network were used. Data from the measurement stations were extrapolated to related sub-basins according to the deposition fields obtained from model calculations (EMEP). For the North Sea, a mean atmospheric trace metal distribution was determined from numerous measurements at a coastal site and over the central North Sea and the annual input was calculated by multiplication with corresponding deposition velocities and scavenging ratios. A comparison of the deposition data based on measurements with those from model calculations show good agreement in the case of Pb in the Baltic Sea as well as in the North Sea. However, for Zn and Cd large discrepancies are observed. Additionally, deposition processes were studied. Scavenging ratios were determined and dry deposition velocities were estimated by the use of a new method for high time resolution measurements of atmospheric trace metal concentrations (impactor/TXRF).

Astronomy from Olbers to Schwarzschild. (German Title: Astronomie von Olbers bis Schwarzschild)

Science.gov (United States)

Dick, Wolfgang R.; Hamel, Jürgen

This issue comprises talks presented 2000 September 18 at the colloquium ``International relations in astronomy'' it is supplemented by additional articles about this topic. The foundation of the international ``Vereinigte Astronomische Gesellschaft'', which took place in 1800 in Bremen, prompted us to investigate the development of astronomy in German-speaking regions, and its international relations during the 19th century. We investigate the activities of famous astronomers like W. Olbers, J.E. Bode, F.X. von Zach, J.H. Schroeter, H.C. Schumacher and K. Schwarzschild, as well as those of their less famous professional colleagues like J.G. Schrader and L. de Ball. The geographical spectrum extends from Bremen and Lilienthal over Kiel, Gotha and Dresden to Copenhagen, Vienna and Chile. Among the topics are: telescope construction, including telescopes made by Herschel, the rediscovery of the minor planet Ceres 1801/02, the Berlin ``Astronomisches Jahrbuch'', the foundation of the ``Astronomische Nachrichten'', the evolution from the ``Vereinigte Astronomische Gesellschaft'' to the present-day ``Astronomische Gesellschaft'', the research at the Kuffner Observatory in Vienna, the professionalization in astronomy, and the attempts of many countries to establish a southern observatory in Chile. A listing of astronomical monuments in Lilienthal and Bremen concludes the book. All papers are written in German with English abstracts.

The objective was to examine longitudinal 4-year-relationships between neighbourhood social environment and children's body mass index-standard deviation score (BMI-SDS) taking into account the built environment. Furthermore, we have analysed the influence of potential interactions between the social environment and family/social data on children's BMI-SDS. Between 2006-2008 and 2010-2012, anthropometric measurements were conducted among 485 children (age at baseline: 6.1 (5.8-6.4)). Socio-demographic characteristics and perception of residential environment were reported by parents. Geographic Information Systems were used to examine street length, number of food outlets and distance to the nearest playground and park/green space within an 800 m Euclidian buffer of each participant address point. Additional data on neighbourhood characteristics (e.g., traffic density, walkability, crime rates) were obtained from the State Capital of Kiel, Germany. In a multivariate model, walkability, street type, socioeconomic status of the district and perceived frequency of passing trucks/buses were associated with BMI-SDS over 4 years, but only neighbourhood SES had an effect on change in BMI-SDS. However, familial/social factors rather than neighbourhood environment (especially social environment) had an impact on children's BMI-SDS over 4 years. Thus, social inequalities in childhood overweight are only partially explained by social neighbourhood environment.

Spatial gradients of GCR protons in the inner heliosphere derived from Ulysses COSPIN/KET and PAMELA measurements

Gieseler, J.; Heber, B.

Context. During the transition from solar cycle 23 to 24 from 2006 to 2009, the Sun was in an unusual solar minimum with very low activity over a long period. These exceptional conditions included a very low interplanetary magnetic field (IMF) strength and a high tilt angle, which both play an important role in the modulation of galactic cosmic rays (GCR) in the heliosphere. Thus, the radial and latitudinal gradients of GCRs are very much expected to depend not only on the solar magnetic epoch, but also on the overall modulation level. Aims: We determine the non-local radial and the latitudinal gradients of protons in the rigidity range from ~0.45 to 2 GV. Methods: This was accomplished by using data from the satellite-borne experiment Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics (PAMELA) at Earth and the Kiel Electron Telescope (KET) onboard Ulysses on its highly inclined Keplerian orbit around the Sun with the aphelion at Jupiter's orbit. Results: In comparison to the previous A> 0 solar magnetic epoch, we find that the absolute value of the latitudinal gradient is lower at higher and higher at lower rigidities. This energy dependence is therefore a crucial test for models that describe the cosmic ray transport in the inner heliosphere.

Evidence suggests that even low-dose irradiation can lead to progressive cognitive decline and memory deficits, which implicates, in part, hippocampal dysfunction in both humans and experimental animals. This study examined whether diethyldithiocarbamate (DDC) could attenuate memory impairment, using passive avoidance and object recognition test, and suppression of hippocampal neurogenesis, using the TUNEL assay and immunohistochemical detection with markers of neurogenesis (Kiel 67 (Ki-67) and doublecortin (DCX)) in adult mice treated with gamma radiation (0.5 or 2 Gy). DDC was administered intraperitonially at a dosage of 1,000 mg{center_dot}kg{sup -1} of body weight at 30 min. before irradiation. In passive avoidance and object recognition memory test, the mice, trained for 1 day after acute irradiation (2 Gy) showed significant memory deficits compared with the sham controls. The number of TUNEL-positive apoptotic nuclei in the dentate gyrus (DG) was increased 12 h after irradiation. In addition, the number of Ki-67- and DCX-positive cells were significantly decreased. DDC treatment prior to irradiation attenuated the memory defect, and blocked the apoptotic death. DDC may attenuate memory defect in a relatively low-dose exposure of radiation in adult mice, possibly by inhibiting a detrimental effect of irradiation on hippocampal neurogenesis.

To evaluate the potential carcinogenic effects of radiofrequency energy (RFE) emitted by cell phones on human thyroid primary cells. Primary thyroid cell culture was prepared from normal thyroid tissue obtained from patients who underwent surgery at our department. Subconfluent thyroid cells were irradiated under different conditions inside a cell incubator using a device that simulates cell phone-RFE. Proliferation of control and irradiated cells was assessed by the immunohistochemical staining of antigen Kiel clone-67 (Ki-67) and tumor suppressor p53 (p53) expression. DNA ploidy and the stress biomarkers heat shock protein 70 (HSP70) and reactive oxygen species (ROS) was evaluated by fluorescence-activated cell sorting (FACS). Our cells highly expressed thyroglobulin (Tg) and sodium-iodide symporter (NIS) confirming the origin of the tissue. None of the irradiation conditions evaluated here had an effect neither on the proliferation marker Ki-67 nor on p53 expression. DNA ploidy was also not affected by RFE, as well as the expression of the biomarkers HSP70 and ROS. Our conditions of RFE exposure seem to have no potential carcinogenic effect on human thyroid cells. Moreover, common biomarkers usually associated to environmental stress also remained unchanged. We failed to find an association between cell phone-RFE and thyroid cancer. Additional studies are recommended.

Subcore observations and high psub(t)

Hazen, W.E.; Hendel, A.Z.; Bull, R.

1981-01-01

The observations of subcores with the Leeds 35m 2 spark chamber array have shown a much lower frequency of subcores than observed at Kiel and at Tokyo with detectors also well suited to observe detailed shower structure. However, overlying material was quite different and the resulting transition effects are difficult to correct for. One seems forced to compare results for subcores occuring only under relatively thin roof material. The discrepancy is thereby nearly removed. As a further test, the Leeds array has recently been run with simulated roof beams above the array. A spin-off from this run is the verification of the ability of our detectors to show ''subcores'' of all sizes and the ability of our scanners to find them. When we calculate psub(t) for our subcores in the traditional manner, no values > 5 GeV/c result. Further, in another paper, we present simulation results showing that there is poor correlation between psub(t) calculated in the usual manner on an event by event basis. The conclusion is that a meaningful utilization of the data requires a comparison of frequency of observable subcore parameters derived from simulations that include QCD nuclear physics to the observed frequencies

Concluding report by the committee of experts on the Brunsbuettel and Kruemmel nuclear power stations. Vattenfall to implement the set of measures and all recommendations

The independent Committee of Experts appointed by Vattenfall Europe after the events of June 28, 2007 in the Brunsbuettel and Kruemmel nuclear power stations concluded its investigations. The Committee had been asked to investigate and evaluate the situation associated with the events, and to elaborate proposals for improvement on this basis. The analysis by the Committee of Experts boils down to the finding that the Brunsbuettel and Kruemmel nuclear power stations represent a modern standard as far as design concepts and technical safety features are concerned. Besides technical preconditions, also the administrative features are in place for safe plant oepration. No indications were found of any deficits in safety culture which would justify doubt about the reliability of the operator or the staff responsible under the Atomic Energy Act, nor is there any doubt about the level of technical expertise. Vattenfall directly ordered the findings to be implemented by applying, for part of the technical measures, for implementation with the Kiel State Ministry for Social Affairs as the competent regulatory agency. The Vattenfall Group is going to establish a new safety organization and safety controlling for the nuclear power plants operated by the company. These measures are to ensure an optimum safety level and the highest safety standards. With Vattenfall, safety enjoys top priority. (orig.)

Lean body mass, consisting mostly of skeletal muscle, is important for healthy aging. We performed a genome-wide association study for whole body (20 cohorts of European ancestry with n = 38,292) and appendicular (arms and legs) lean body mass (n = 28,330) measured using dual energy X-ray absorptiometry or bioelectrical impedance analysis, adjusted for sex, age, height, and fat mass. Twenty-one single-nucleotide polymorphisms were significantly associated with lean body mass either genome wide (p lean body mass and in 45,090 (42,360 of European ancestry) subjects from 25 cohorts for appendicular lean body mass was successful for five single-nucleotide polymorphisms in/near HSD17B11, VCAN, ADAMTSL3, IRS1, and FTO for total lean body mass and for three single-nucleotide polymorphisms in/near VCAN, ADAMTSL3, and IRS1 for appendicular lean body mass. Our findings provide new insight into the genetics of lean body mass.Lean body mass is a highly heritable trait and is associated with various health conditions. Here, Kiel and colleagues perform a meta-analysis of genome-wide association studies for whole body lean body mass and find five novel genetic loci to be significantly associated.

Full Text Available New isolates of Streptomyces champavatii were isolated from marine sediments of the Gotland Deep (Baltic Sea, from the Urania Basin (Eastern Mediterranean, and from the Kiel Bight (Baltic Sea. The isolates produced several oligopeptidic secondary metabolites, including the new octapeptide champacyclin (1a present in all three strains. Herein, we report on the isolation, structure elucidation and determination of the absolute stereochemistry of this isoleucine/leucine (Ile/Leu = Xle rich cyclic octapeptide champacyclin (1a. As 2D nuclear magnetic resonance (NMR spectroscopy could not fully resolve the structure of (1a, additional information on sequence and configuration of stereocenters were obtained by a combination of multi stage mass spectrometry (MSn studies, amino acid analysis, partial hydrolysis and subsequent enantiomer analytics with gas chromatography positive chmical ionization/electron impact mass spectrometry (GC-PCI/EI-MS supported by comparison to reference dipeptides. Proof of the head-to-tail cyclization of (1a was accomplished by solid phase peptide synthesis (SPPS compared to an alternatively side chain cyclized derivative (2. Champacyclin (1a is likely synthesized by a non-ribosomal peptide synthetase (NRPS, because of its high content of (d-amino acids. The compound (1a showed antimicrobial activity against the phytopathogen Erwinia amylovora causing the fire blight disease of certain plants.

Evidence suggests that even low-dose irradiation can lead to progressive cognitive decline and memory deficits, which implicates, in part, hippocampal dysfunction in both humans and experimental animals. This study examined whether diethyldithiocarbamate (DDC) could attenuate memory impairment, using passive avoidance and object recognition test, and suppression of hippocampal neurogenesis, using the TUNEL assay and immunohistochemical detection with markers of neurogenesis (Kiel 67 (Ki-67) and doublecortin (DCX)) in adult mice treated with gamma radiation (0.5 or 2 Gy). DDC was administered intraperitonially at a dosage of 1,000 mg·kg -1 of body weight at 30 min. before irradiation. In passive avoidance and object recognition memory test, the mice, trained for 1 day after acute irradiation (2 Gy) showed significant memory deficits compared with the sham controls. The number of TUNEL-positive apoptotic nuclei in the dentate gyrus (DG) was increased 12 h after irradiation. In addition, the number of Ki-67- and DCX-positive cells were significantly decreased. DDC treatment prior to irradiation attenuated the memory defect, and blocked the apoptotic death. DDC may attenuate memory defect in a relatively low-dose exposure of radiation in adult mice, possibly by inhibiting a detrimental effect of irradiation on hippocampal neurogenesis.

Two types of tertiary amine oxidation processes, namely, N-dealkylation and N-oxygenation, by compound I (Cpd I) of cytochrome P450 are studied theoretically using hybrid DFT calculations. All the calculations show that both N-dealkylation and N-oxygenation of trimethylamine (TMA) proceed preferentially from the low-spin (LS) state of Cpd I. Indeed, the computed kinetic isotope effects (KIEs) for the rate-controlling hydrogen abstraction step of dealkylation show that only the KIE(LS) fits the experimental datum, whereas the corresponding value for the high-spin (HS) process is much higher. These results second those published before for N,N-dimethylaniline (DMA), and as such, they further confirm the conclusion drawn then that KIEs can be a sensitive probe of spin state reactivity. The ferric-carbinolamine of TMA decomposes most likely in a non-enzymatic reaction since the Fe-O bond dissociation energy (BDE) is negative. The computational results reveal that in the reverse reaction of N-oxygenation, the N-oxide of aromatic amine can serve as a better oxygen donor than that of aliphatic amine to generate Cpd I. This capability of the N-oxo derivatives of aromatic amines to transfer oxygen to the heme, and thereby generate Cpd I, is in good accord with experimental data previously reported.

The Baltic Sea is characterized by low salinity and pronounced fluctuations in pCO2. On-line monitoring of pCO2 in 2014 in Kiel Fjord demonstrated occurrence of peak values of >2,000 µatm in summer and autumn and average values >750 µatm. We assessed the impacts of elevated temperature (ambient temperature, ambient +3°C) and pCO2 (500, 1,500, 2,400 µatm) on the keystone species Asterias rubens in a fully crossed long - term experiment (N=5 replicate tanks each, 1 year duration). During spring and early summer (February - June), high temperature animals ingested significantly more food and spawned significantly earlier (April 30th) than ambient acclimated animals (May 23rd). Elevated pCO2 led to comparatively minor reductions in food intake and scope for growth during that period. During summer (June - August), elevated temperature >25°C caused negative energy budgets and >95% mortality in the warm acclimated groups, while mortality was low in the ambient temperature groups. Our results indicate that A. rubens may benefit from increased temperature during colder months, yet dramatically suffer during summer heat waves in warm years. Meaningful experimental approaches to assess species vulnerability to climate change need to encompass all seasons and realistic abiotic stressor levels.

Blaetter der Erinnerung - Leaves of Memory - an autobiography

Science.gov (United States)

Kobold, H. A.

2004-12-01

The following notes of the blind author, entitled "leaves of memory" were written in 1940, two years before his death. The notes, which were written by hand with the aid of a special deskpad, were later transcribed. The present condition contains the complete text; only incorrectly written or transcribed names of persons or geographical places were corrected. The autobiography covers Hermann Kobold's youth and education in Hannover (1858-1877), his scientific studies at Goettingen University (1877-1880), the time as an assistant at Nicolaus von Konkoly's private observatory (1880-1883), his participation in the Venus transit expedition to Aiken, South Carolina (1882), his work for the German Venus Transit Commission in Berlin (1883-1886), and his years as an observer and professor at the University Observatory in Strasbourg (1886-1902). The notes come to a close with Kobold's departure from Strasbourg to accept a position at Kiel University Observatory. The autobiography give a subjective view of scientific and university life in the last decades of the 19th century, a view which is, however, free from any "self-censured" texts like annual reports or obituaries. The notes offer rare insights, e.g. in the behaviour of Kobold's contemporaries and the influence exercised in the case of appointments.

Les Fleurs bleues (R. Queneau

Full Text Available Les Fleurs bleues, roman paru en 1965, propose un fascinant voyage dans le temps et dans l'espace géographique des langues, une odyssée au cœur de la problématique babélienne dont il se fait le porte-parole. Queneau joue sur les particularités linguistiques, les idiolectes et les syntaxes dans une perspective transhistorique et cosmopolite, créant un nouvel esperanto romanesque : le « néobabélien ». Toutes les langues s'interpénètrent et se correspondent, enrichissent l'écriture de l'œuvre et dévoilent peu a peu ses prolongements à la fois scientifiques et philosophiques. Queneau élabore ainsi son propre système linguistique et littéraire, dans ce laboratoire de l'arche romanesque, où la langue future est en gestation.Reprenant le flambeau de Noé, l'écrivain entraîne ses lecteurs dans une traversée du déluge qui mêle le rêve et la réalité, l'humour et la nostalgie – celle de la langue unique, la virtuosité du style et la rigueur de la composition. Le roman démantèle les frontières historiques et géographiques, faisant ainsi de Noé une nouvelle figure de l'artiste, sauveur et reconstructeur du Verbe, et chantre de l'infinie potentialité du langage. Non sans humour, son esthétique se fonde sur une dialectique de la contrainte et de la liberté, de la destruction et de la reconstruction, soutenue par un style vif et corrosif. Le conteur, le poète et le mathématicien se rejoignent et conjuguent leur sagesse dans ce roman complexe et déroutant, récit à clés d'une expérience linguistique originale et approfondie.The novel Les Fleurs bleues, which was published in 1965, is an invitation to a fascinating journey into the time and space dimensions of languages, an odyssey into the heart of the Babelian problematics which it publicizes. Queneau plays upon linguistic particularities, idiosyncrasies and syntaxes within a historical and cosmopolitan perspective, and creates a new Esperanto for the novel: the

The objective was to examine longitudinal 4-year-relationships between neighbourhood social environment and children’s body mass index-standard deviation score (BMI-SDS) taking into account the built environment. Furthermore, we have analysed the influence of potential interactions between the social environment and family/social data on children’s BMI-SDS. Between 2006–2008 and 2010–2012, anthropometric measurements were conducted among 485 children (age at baseline: 6.1 (5.8–6.4)). Socio-demographic characteristics and perception of residential environment were reported by parents. Geographic Information Systems were used to examine street length, number of food outlets and distance to the nearest playground and park/green space within an 800 m Euclidian buffer of each participant address point. Additional data on neighbourhood characteristics (e.g., traffic density, walkability, crime rates) were obtained from the State Capital of Kiel, Germany. In a multivariate model, walkability, street type, socioeconomic status of the district and perceived frequency of passing trucks/busses were associated with BMI-SDS over 4 years, but only neighbourhood SES had an effect on change in BMI-SDS. However, familial/social factors rather than neighbourhood environment (especially social environment) had an impact on children’s BMI-SDS over 4 years. Thus, social inequalities in childhood overweight are only partially explained by social neighbourhood environment. PMID:24132135

For the 50 th anniversary, atw remembers an important part of nuclear technology history in Germany: The research and freight ship shows one thing above all in retrospect: The technology ran reliably. But cost pressure and reservations shattered the dream of a nuclear power shipping era. Until it was decommissioned in 1979 the ship travelled a total of 650,000 sea miles and called at 33 harbours in 22 countries. On the research level, the 'Otto Hahn' could satisfy expectations, however, it could not ring in an era of nuclear shipping - the atomic boat could never cover its operating costs with its freight trips and permission to call at foreign ports were rare. However, on the one hand, the ship's journeys, sometimes under hard weather conditions, demonstrated just how robust and durable the 'progressive pressurized water reactor' on board was, on the other hand, the 'Otto Hahn' had by all means been a prototype which under other market conditions could have been a model for nuclear container ships. In any case, it proved the performance capacity of the then still young German and European nuclear technology industry, that did not need to hide behind the Russian and American competition.

Soon after announcement of the first American ether anesthesias in 1846 one started to anesthetize with ether in Europe. The first ether anesthesia in Germany took place on January 24th, 1947, and was given by Johann Ferdinand Heyfelder in Erlangen. Two weeks later the first ether anesthesia in Berlin was given on February 6th, 1847, by the orthopaedic surgeon Heimann-Wolff Berend. On February 12th, 1847, the surgeon Johann Friedrich Dieffenbach used ether to anesthetize a patient in the Berlin university hospital. Still in 1847 he published his book "The Ether against Pain" which used to be the standard textbook of anesthesia in Germany for many years to come. On February 15th, 1847, Johann Christian Jüngken operated his first patient under ether anesthesia in the surgical department of the Charité hospital assisted by Rudolf Virchow. Since then several famous Berlin surgeons influenced the development of modern anesthesia until the middle of the 20th century. The nitrous oxide bottle was introduced into practice by the Barth company in cooperation with the dentist Carl Sauer and Kurt Schimmelbusch introduced his mask for ether anesthesia. Carl Ludwig Schleich reported at the German congress of surgery in 1894 about his first experience with infiltration anesthesia. Spinal anesthesia developed by August Bier in Kiel was improved during his time in Berlin.

Mars science laboratory radiation assessment detector (MSL/RAD) modeling workshop proceedings

The Radiation Assessment Detector (RAD) (Hassler et al., 2012; Zeitlin et al., 2016) onboard the Mars Science Laboratory (MSL) Curiosity rover (Grotzinger et al., 2012) is a sophisticated charged and neutral particle radiation analyzer developed by an international team of scientists and engineers from Southwest Research Institute in Boulder, Colorado as the leading institution, the University of Kiel and the German Aerospace Center in Cologne, Germany. RAD is a compact, powerful instrument capable of distinguishing between ionizing particles and neutral particles and providing neutron, gamma, and charged particle spectra from protons to iron as well as absorbed dose measurements in tissue-equivalent material. During the 6 month cruise to Mars, inside the MSL spacecraft, RAD served as a proxy to validate models of the radiation levels expected inside a spacecraft that future astronauts might experience (Zeitlin et al., 2013). RAD was turned on one day after the landing on August 7, 2012, exactly 100 years to the day after the discovery of cosmic rays on Earth by Victor Hess. These measurements are the first of their kind on the surface of another planet (Hassler et al., 2014), and the radiation data collected by RAD on the surface of Mars will inform projections of crew health risks and the design of protective surface habitats and other countermeasures for future human missions in the coming decades.

δ13C and δ18O measurements of carbonate rocks using Cavity Ring-Down Spectroscopy

Lucic, G.; Kim-Hak, D.; Curtis, J. H.

2017-12-01

We present a novel, user friendly and cost effective method for the analysis of δ13C and δ18O in CO2 gas obtained from acid digestion of carbonate rocks. 2 to 3 milligrams of pure carbonate, ground to a powder, is digested in a pre-evacuated glass vial using 100% phosphoric acid at 70° C. Vials with the reacted samples are then loaded onto an automated carousel sampler where produced CO2 gas in the headspace is extracted and sent to a Picarro CRDS isotopic C and O analyzer. Once loaded onto the carousel, 49 samples may be analyzed automatically at a rate of one sample every 15 minutes. δ13C and δ18O of the sample are reported in real time with a precision of 0.2 and 0.4 per mil, respectively. The portability and simplicity of the autosampler and CRDS setup opens up potential for permanent and mobile deployments, enabling near-realtime sampling feedback in the lab or on the go in the field. Consumable and operating costs are small when compared to other technology in use, making the CRDS-Carbonate system suitable for large and small research labs. Finally, we present a summary results from a series of validation tests in which standards and natural carbonate rock samples were analyzed and compared to traditional Kiel-IRMS results.

The spacecraft Ulysses was launched in October 1990 in the maximum phase of solar cycle 22, reached its final, highly inclined (80.2°) Keplerian orbit around the Sun in February 1992, and was finally switched off in June 2009. The Kiel Electron Telescope (KET) aboard Ulysses measures electrons from 3 MeV to a few GeV and protons and helium in the energy range from 6 MeV/nucleon to above 2 GeV/nucleon. In order to investigate the radial and latitudinal gradients of galactic cosmic rays (GCR), it is essential to know their intensity variations for a stationary observer in the heliosphere because the Ulysses measurements reflect not only the spatial but also the temporal variation of the energetic particle intensities. This was accomplished in the past with the Interplanetary Monitoring Platform-J (IMP 8) until it was lost in 2006. Fortunately, the satellite-borne experiment PAMELA (Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics) was launched in June 2006 and can be used as a reliable 1 AU baseline for measurements of the KET aboard Ulysses. With these tools at hand, we have the opportunity to determine the spatial gradients of GCR protons and alpha particles at about 0.1 to 1 GeV/n in the inner heliosphere during the extended minimum of solar cycle 23. We then compare these A0 cycle.

still do. The creation of data set as additional publications is an additional workload a lot of scientists are not yet convinced about. These times are coming to an end now because of the efforts of the funding organisations and the increased awareness of scientific institutions. Right now data archives have their expertise in retrievability and availability, but the new demand of data provenance is not yet included in their systems. So why not taking the chance of the scientific institutes sneaking in and split the workload of retrievability and provenance. Such an integrated data environment will be characterized by increased functionality, creditability and structured data from the creation and everything accompanied by data managers. The Kiel Data Management Infrastructure is creating such an institutional provenance system for the scientific site of Kiel. Having data sets up to date by synchronisation with institutional provenance system capturing all changes and improvements right where they happen. A sophisticated and scalable landscape needs to combine advantages of the existing data centers such as the usability and retrievability functionality with the advantages of decentralised data capturing and provenance. This data environment with synchronisation features and creditability of scientific data to future users would be capable of the future tasks.

To assess the effect of an antismoking advertisement under real-world conditions. Design Quasi-experimental study. Multiplex cinema in Kiel, Germany; 4073 patrons were surveyed after having viewed a movie. Some 4005 patrons were > or = 10 years old (28.7% between 10 and 17 years). A total of 654 subjects (16.3%) were smokers. In the intervention condition (weeks 1 and 3), a 30-second antismoking advertisement-accentuating long-term health consequences of smoking and promoting cessation-was shown prior to all movies; in the control condition (weeks 2 and 4) no such spot was shown. (i) Awareness of smoking in the movie, (ii) approval of smoking in the movie, (iii) attitude towards smoking, (iv) intention to smoke in the future and (v) desire to smoke among smokers. Findings Patrons who were exposed to the antismoking advertisement were more likely to be female, but did not differ with respect to smoking status. After controlling for gender differences, patrons exposed to the antismoking advertisement had (i) higher awareness of smoking in the movies, (ii) lower levels of approval of smoking in the movies, and (iii) a more negative attitude towards smoking in general compared with those not exposed. Among smokers, smoking in the movies increased urge to smoke, but there was no interaction between smoking in the movies and experimental condition. Study results suggest that placing an antismoking advertisement before movies can affect attitudes towards smoking, bolstering evidence in support of such policies.

Full Text Available Since the migration to DSpace, an internationally widely used digital repository software, at the beginning of 2009, the “German National Library for Economics” (ZBW presents its repository with a new website and a new name: EconStor. In addition to the considerable number of working and discussion papers – predominately edited from economics faculties and research institutes in Germany and collected via its predecessor application OPUS – ZBW intends to acquire further document types, especially postprints. Numerous researchers from the Kiel Institute for the World Economy are already using EconStor for open access publishing within the framework of the EU-funded project entitled „Network of European Economists Online“ (NEEO. It is of utmost importance for a subject-based repository to be cross-linked with the well-established databases and other resources dedicated to its subject area in order to achieve a wide dissemination and reception within its own scientific community. Besides providing metadata of several working paper series to the bibliographic database „Research Papers in Economics“ (RePEc, ZBW plans to establish a similar service for the renowned „Social Science Research Network“ (SSRN by setting up an interface to SSRN’s eLibrary. A basic requirement to realize these intentions is a flexible document management system which is open to the adaptations needed to fulfill these specifications. The criteria which led to the decision for DSpace as repository software will be explained.

Trace metal fluxes to ferromanganese nodules from the western Baltic Sea as a record for long-term environmental changes

Trace element profiles in ferromanganese nodules from the western Baltic Sea were analyzed with laser ablation inductively coupled plasma mass spectroscopy (LA-ICP-MS) and synchrotron-based micro-X-ray radiation techniques (fluorescence: mSXRF, and diffraction: mXRD) at high spatial resolution in growth direction. Of the trace elements studied (Zn, Cu, Cd, Ni, Co, Mo, Ba), Zn showed the most significant enrichment, with values in the outermost surface layers of up to six-fold higher than those found in older core parts. The high-resolution Zn profiles provide the necessary temporal resolution for a dating method analogous to dendrochronology. Profiles in various samples collected during two decades were matched and the overlapping sections used for estimation of the accretion rates. Assuming a continuous accretion of these relatively fast growing nodules (on average 20 mm a-1) over the last century, the Zn enrichment was thus assessed to have commenced around 1860/70 in nodules from the Kiel Bight and in 1880/90 from Mecklenburg Bight, reflecting the enhanced heavy metal emissions with rising industrialization in Europe. Apart from the obvious success with Zn, only As and Co show significant but only 1.5-fold enrichments in the most recent growth layers of the nodules. Other anthropogenic trace metals like Cu and Cd are not at all enriched, which, together with the distinct early-diagenetic Fe/Mn banding, weakens the potential of the nodules for retrospective monitoring.

Terra nullius, Inuit Habitation and Norse Occupation – With Special Emphasis on the 1933 East Greenland Case

Directory of Open Access Journals (Sweden)

Peter Thomas Ørebech

2016-05-01

Full Text Available Sovereignty acquired by occupation entails “recognize[d] title based on discovery,” “a reasonable period [of] … effective occupation of the region claimed to be discovered” and “the continuous and peaceful display of State authority.” Only terra nullius is subject to occupation. A territory inhabited by indigenous groups that sustain social and political organization may impede an occupying power because the terra nullius requirement fails. While sovereignty over thinly populated areas are often lax, case law requires less public involvement in these sparsely inhabited areas. This study reveals that the Dano-Norwegian Kings regarded the Inuit as “our subjects.” The Kings’ pretention of absolutum dominium and jurisdiction involved both the Norse and Inuit ethnic groups and “bygð ok ubygð” (settled and unsettled land. The exodus of the Norse peoples in 1450 AD for 200 years did not undermine the acquired sovereignty of the Dano-Norwegian Crown, which as a result, spoiled the 1931 Norwegian pretentions to legally occupy East-Greenland. Denmark's triumph in the 1933-East Greenland case resulted from a “zero-sum principle.” More than a 100 years earlier, the Danish Kingdom lost a succession of countries and dependencies. The 1814 Kiel Treaty transferred mainland Norway to Sweden, but explicitly states that none of the ancient Norwegian dependencies, Greenland, Iceland and Faroe Islands would follow suit. Thus, these territories remained part of the Kingdom of Denmark.

Fractionated homogenous total-body irradiation prior to bone marrow transplantation

At the University of Kiel, myeloid and acute lymphatic leukemia is treated since 1983 by total-body irradiation applied prior to bone marrow transplantation. Dose deviations in the midplane caused by the irregular surface and tissue inhomogeneities of the patient are reduced down to +-3.5% compared to the central ray, with the help of CT-based individual compensators. This method prevents above all an excessive dose to the lungs. The radiobiologic advantages of fractionated irradiation have been employed for all patients treated hitherto (n = 9). At present, a total body dose of 12 Gy in six fractions is applied within three days. There were no undesired acute radiogenic reactions except a mild acute mucositis found in all patients. Chronic side effects, especially in the lungs, were not demonstrated, too. However, the average follow-up time of 149 days has been rather short. One patient died from relapse of leukemia after a total dose of 10 Gy, another patient died because the transplanted bone marrow was rejected, and a third died from catheter sepsis. Six out of nine patients are in complete remission with a maximum index of Karnofsky. The limited experiences gained hitherto show that the homogeneous accelerated-fractionated total-body irradiation offers essential advantages compared to non-compensated single dose irradiation with respect to the prevention of undesired radiogenic effects in sound tissues and that its therapeutic efficacy is at least the same.

The paper summarises the accessible literature on the life and work of well-known American lung surgeon, Professor Dr. Med. Robert Klopstock, who was in the years 1920-1924 a friend Franz Kafka. Professor Klopstock was of Hungarian origin and he got acquainted with Franz Kafka at the end of the year 1920 in Tatranské Matliare (The High Tatras). They were both patients treated for lung tuberculosis. They became close friends and their mutual correspondence shows their real friendship. Robert Klopstock was present at Franz Kafka's death-bed on June 3, 1924 in Kierling, near Klosterneuburg, not far from Vienna. Robert Klopstock studied at Medical Faculties of the Universities in Budapest, Prague, Kiel and Berlin. After his graduation in 1933 in Berlin, he worked as a lung surgeon at various surgical clinics and departments in Budapest and Berlin. In 1936 Robert Klopstock together with his wife visited the High Tatras and Tatranské Matliare. In 1937 Robert Klopstock with his wife Gizela, a writer and a translator, who translated the first chapters of Franz Kafka's novel "Trial" into Hungarian language, went to United States of America. During his stay in U.S.A. Dr. Med. Robert Klopstock was very active as a lung surgeon and a scientist. He published 64 specialized scientific papers, mostly in American medical journals. He became Professor of Lung Surgery at Downstate Medical Centre in New York-Brooklyn. He died on June 15, 1972 in New York.

The aim of this study was to evaluate the long-term dental implant survival rates of Straumann dental implants in a university hospital environment over 12 to 23 years. A total of 388 Straumann dental implants with titanium-sprayed surfaces (TPS) were inserted in 92 patients between 1988 and 1999 in the Department of Oral and Maxillofacial Surgery of the University Hospital Schleswig-Holstein in Kiel, and they were reevaluated with standardized clinical and radiological exams. Kaplan-Meier analyses were performed for individual factors. Cox proportional hazard regression analysis was used to detect the factors influencing long-term implant failure. The long-term implant survival rate was 88.03% after an observation time of 12.2 to 23.5 years. Cox regression revealed statistically significant influences of the International Team for Implantology (ITI) implantation type (p = .00354) and tobacco smoking (p = .01264) on implant failure. A proportion 82.8% of the patients with implant losses had a medical history of periodontitis. Peri-implantitis was diagnosed in 9.7% of the remaining implants in the long-term survey. This study emphasized the long-term rehabilitation capabilities of Straumann dental implants in complex cases. The survival rates after several years constitute important information for patients, as well as for clinicians, in deciding about different concepts of tooth replacement. Patient-related and technical factors - determined before implant placement - could help to predict the risk of implant loss. © 2015 Wiley Periodicals, Inc.

The shortage of qualified doctors and nurses has led to a competition between hospitals. Analyzing the circumstances of the competition, nurses and doctors of so-called generation Y are important. These employees are mainly female and have different requirements compared to previous generations. Therefore, knowledge of these requirements will become a critical success factor for hospitals in the future. We interviewed medical students in Kiel and Hannover from 2005 to 2011 about the clinical department chosen, the criteria for choosing a specific clinic, and the importance of MD and PhD programs. In addition, we conducted an internet and Medline search for scientific studies on labor shortage, generation Y, and demographics. The data were sorted by main categories and relevance for hospitals. Statistical analyses were performed using descriptive measures. We received 1,097 answers which represents approx. 75% of all students. Sixty-seven percent of the students were female, 33% male. Preferences for departments revealed internal medicine, pediatrics, and anesthesiology as the top three. ENT followed at rank 10. The main criteria for choosing a clinic were working climate, structure and broadness of education, family friendliness, and respect. MD programs were rated 2.6, while PhD programs were rated 3.6. Staff members of Generation Y "live while working" and disagree with hierarchies. Internet and computers are part of their daily routine. Employees of Generation Y challenge leadership in hospitals by increasing demands. However, Generation Y can increase professionalization and competitiveness for hospitals significantly.

Full Text Available Amr A Faddan, Alexey V Aksenov, Carsten M Naumann, Klaus P Jünemann, Daniar K Osmonov Department of Urology and Pediatric Urology, University Hospital Schleswig-Holstein, Kiel, Germany Introduction: Priapism is the persistent erection resulting from dysfunction of the mechanisms that regulate penile swelling, stiffness, and sagging. It is a full or partial erection that persists for a period more than 4 hours beyond sexual stimulation and/or orgasm or is unrelated to sexual stimulation. Ischemic priapism should be managed in a step-by-step fashion. Objective: To demonstrate step-by-step management of stuttering refractory ischemic priapism. We report a case of stuttering refractory ischemic priapism. Moreover, we reviewed different approaches to priapism management in the literature. Case presentation: A 53-year-old male presented with a painful erection of 29 hours’ duration, probably caused by consumption of alcohol. The penile blood gas showed a pH of 7.08, PCO2 of 75 mmHg and PO2 of 39 mmHg. Aspiration was followed by irrigation of an α-adrenergic, Winter and T-shunt operations were preformed, and finally a semi-rigid penile prosthesis was implanted to overcome the refractory stuttering ischemic priapism. Conclusion: In case of stuttering refractory ischemic priapism, immediate implantation of a penile prosthesis is a simple and effective procedure that manages both the acute episode and the inevitable erectile dysfunction that would otherwise occur, while preserving penile length. Keywords: priapism, stuttering priapism, shunting operation, penile prosthesis

There is sufficient evidence showing the positive effects of physical exercise on various aspects of pregnancy. This study evaluates knowledge and status of physical exercise among pregnant women. The standardised paper-pencil questionnaire "Pregnancy Physical Activity Questionnaire" (PPAQ) as well as general demographic questions were used to assess the exercise behaviour of study participants. 83 questionnaires completed by women presenting to the Kiel University Hospital for antenatal assessment were included in the analysis. At the time of questionnaire completion 10 women were in the first trimester of pregnancy, 64 in the second, and 9 in the third. Just less than 90% of participants felt they had been informed "sufficiently" on the topic physical exercise during pregnancy, over 50% felt they were "well" or "very well" informed. Just less than half of participants received their information from a doctor (either their gynaecologist or general practitioner) and none of these felt "insufficiently" informed. Almost 80% of participants reported still doing no sport or less exercise than before falling pregnant. The maximum proportional energy expenditure for recreational activity - just under 20% - was in the third trimester. Women who felt they had been well counselled tended to have higher activity levels. Study participants demonstrated a clear decline in physical exercise during pregnancy despite clear evidence of the benefits of regular exercise for pregnant women, and despite participants feeling they were well informed. Detailed information on the recommendations for physical exertion in pregnancy should form an integral part of antenatal counselling.

Middle Eocene (Bartonian) Nummulites perforatus bank from the Transylvanian Basin, Romania: an example from a classical occurrence

Giant uni-cellulars, Nummulites lived in stable oligotrophic environments throughout the Eocene of the Tethys forming large accumulations called "banks" (Arni, 1965), which were identified on the top of the Cǎpusu Formation, Transylvanian Basin (Popescu, 1978). The studied outcrop is located near Cǎpusu village, Cluj County where we studied two sections (CA1, CA2). They consist of medium to coarse grained sands with abundant Nummulites perforatus (A and B forms). Sporadically specimens of Nummulites beaumonti are also present. According to the larger foraminiferal zonation of Serra-Kiel et al. (1998) the studied nummlitic bank is referred to the SBZ 17 Zone (early Bartonian). Specimens were recovered from 6 samples, about 2 kg each, prepared by standard methods. In section CA1 the A/B ratio ranges between 42/1 and 117/1 while in section CA2 the A/B ratio varies between 27/1 and 52/1. The higher A/B ratio suggests that the original Nummulites assemblages was winnowed in situ. By contrast, the lower A/B ratio indicates that the original assemblage was supposedly selectively winnowed (Ainger, 1985), but they are in situ (Seddighi et al., 2015). This interpretation is supported by the fact, that in all samples the Nummulites specimens (both A and B form) are bioeroded and abraded, which indicates a shallow water environment with high hydrodynamic activity (Racey, 2001; Papazzoni, 2008). Based on our observations the studied nummulitic accumulations consist mostly of monospecific assemblages, and they form a bank. The identified biofabrics, the A/B ratio of the assemblages and the presence of both A and B forms support this interpretation. The presence of the abraded Nummulites tests further suggest that the studied deposits were sedimented in a shallow water environment with high hydrodynamic activity, probably in a wave dominant setting.

Professor Frantisek Por MD and Professor Robert Klopstock MD were contemporaries, both born in 1899, one in Zvolen, the other in Dombovar, at the time of Austro-Hungarian Monarchy. Prof. Por attended the Faculty of Medicine in Budapest from 1918 to 1920, and Prof. Klopstock studied at the same place between 1917 and 1919. From 1920 until graduation on 6th February 1926, Prof. Por continued his studies at the German Faculty of Medicine, Charles University in Prague. Prof. Klopstock had to interrupt his studies in Budapest due to pulmonary tuberculosis; he received treatment at Tatranske Matliare where he befriended Franz Kafka. Later, upon Kafka's encouragement, he changed institutions and continued his studies at the German Faculty of Medicine, Charles University in Prague, where he graduated the first great go. It is very likely that, during their studies in Budapest and Prague, both professors met repeatedly, even though their life paths later separated. Following his graduation, Prof. Por practiced as an internist in Prague, later in Slovakia, and from 1945 in Kosice. In 1961, he was awarded the title of university professor of internal medicine at the Faculty of Medicine, Pavol Jozef Safarik University in Kosice, where he practiced until his death in 1980. Prof. Klopstock continued his studies in Kiel and Berlin. After his graduation in 1933, he practiced in Berlin as a surgeon and in 1938 left for USA. In 1962, he was awarded the title of university professor of pulmonary surgery in NewYork, where he died in 1972.

Particle acceleration in binaries

Full Text Available Cygnus X-3 massive binary system is one of the powerful sources of radio and X-ray emission consisting of an accreting compact object, probably a black hole, with a Wolf-Rayet star companion. Based on the detections of ultra high energy gamma-rays by Kiel and Havera Park, Cygnus X-3 has been proposed to be one of the most powerful sources of charged cosmic ray particles in the Galaxy. The results of long-term observations of the Cyg X-3 binary at energies 800 GeV–85 TeV detected by SHALON in 1995 are presented with images, integral spectra and spectral energy distribution. The identification of source with Cygnus X-3 detected by SHALON was secured by the detection of its 4.8 hour orbital period in TeV gamma-rays. During the whole observation period of Cyg X-3 with SHALON significant flux increases were detected at energies above 0.8 TeV. These TeV flux increases are correlated with flaring activity at a lower energy range of X-ray and/or at observations of Fermi LAT as well as with radio emission from the relativistic jets of Cygnus X-3. The variability of very high-energy gamma-radiation and correlation of radiation activity in the wide energy range can provide essential information on particle mechanism production up to very high energies. Whereas, modulation of very high energy emission connected to the orbital motion of the binary system, provides an understanding of the emission processes, nature and location of particle acceleration.

Differential typology and prognosis for dissexual behavior--a follow-up study of previously expert-appraised child molesters.

Science.gov (United States)

Beier, K M

1998-01-01

In terms of identifying socially-dysfunctional forms of sexuality--regardless of the legal valuation--dissexuality is defined as "an expression of social failure in sexual behavior." This failure was the subject of a longitudinal analysis of 186 expert-appraised pedophile sexual delinquents at the University of Kiel from 1945 through 1981. Of the child molesters 121 were followed up between September 1990 and September 1992 and 100 were personally contacted. The goal was to empirically develop prognosis criteria, given knowledge of the former delinquents' social development as well as sexual/dissexual practices, which could be of both forensic and interdisciplinary use. Among the bi- and homosexually-orientated pedophiles, the number of offenders for which the act is one of "compensation" was half of the initial collective. In contrast, this number was three-quarters for the heterosexually-orientated perpetrators. Correspondingly, the other half of the bi- and homosexually-orientated pedophiles were either exclusive-type or non-exclusive-type pedophiles (the so-called "true" pedophiles). Among the heterosexually-orientated offenders, the number was only one-quarter. According to the empirical data, we may expect a biographically continuing potential of dissexual behavior for only the exclusive and the non-exclusive type of pedophilia. Most of the relapsed dissexual activities showed up a long time after the expert's report. This is true for both the heterosexually- and the bi- and homosexually orientated groups. The present evaluation of the results allows assignment of behavior for certain delinquent typologies restricted to life phases or lifelong dissexual behavior.

The International Psoriasis Council, a global nonprofit organization dedicated to advancing psoriasis research and treatment, led an initiative to better define the pathogenic mechanisms that constitute psoriasis. In September 2012, a workshop was held at the 42nd Annual European Society for Dermatological Research in Venice, Italy. By assembling a panel of global dermatology and immunology experts, the objective was to evaluate the current status of the science explaining the mechanism of disease in psoriasis, e.g. dysregulation of the skin immune system and perturbations of epidermal homeostasis. The workshop consisted of four oral presentations, which addressed key topics in psoriasis, delivered by Hervé Bachelez (Paris, France), Antonio Costanzo (Rome, Italy), Michelle Lowes (New York, NY, U.S.A.) and Frank Nestle (London, U.K.). A global expert panel was assembled to stimulate dialogue and debate: Kevin Cooper (Cleveland, OH, U.S.A.), Michel Gilliet (Lausanne, Switzerland), Joerg Prinz (Munich, Germany), Martin Röcken (Tubingen, Germany), Jens Schroeder (Kiel, Germany), Manuelle Viguier (Paris, France), Mayte Suárez-Fariñas (New York, NY, U.S.A.) and Cristina Zielinski (Berlin, Germany). Collectively, the presentations demonstrated the significant advances in understanding immune regulation that have occurred over the past decade by virtue of the study of psoriasis subtypes, phenotypic manifestations and genetic associations. Elucidating the pathogenic and genetic basis of psoriasis holds the promise of a complete understanding of disease mechanisms, predictors of treatment response, novel drug development strategies and customized therapeutic regimens for the individual patient. © 2013 The Authors BJD © 2013 British Association of Dermatologists.

A Single and Comprehensive Helios Data Archive

Salem, C. S.

2017-12-01

Helios 1 & 2 rank amoung the most important missions in Heliophysics, and the more-than 11 years of data returned by its spacecraft remain of paramount interests to researchers. Their unique trajectories which brought them closer to the Sun than any spaceccraft before or since, enabled their diverse suite of in-situ instruments to return measurements of unprecedented scientific richness. There is however no comprehensive public repository of all Helios in-situ data. Currently, most of the highest resolution data can be obtained from a variety of places, although highly processed and with very little documentation, especially on calibration. Analysis of this data set requires overcoming a number of technical and instrumental issues, knowledge and expertise of which is only possessed by the original PI's of the Helios experiments. We present here a work funded by NASA of aggregating, analyzing, evaluating, documenting and archiving the available Helios 1 and 2 in-situ data. This work at the UC Berkeley Space Sciences Laboratory is being undertaken in close collaboration with colleagues at the University of Koln, at the University of Kiel, at the Imperial College in London and at the Paris Observatory. A careful, detailed, analysis of the Helios fluxgate and search coil magnetic field data as well as plasma data has revealed numerous issues and problems with the available, processed, datasets, that we are still working to solve. We anticipate this comprehensive single archive of all Helios in-situ data, beyond its inherent scientific value, will also be an invaluable asset to the both the Solar Probe Plus and Solar Orbiter missions.

Intra-population variability of ocean acidification impacts on the physiology of Baltic blue mussels (Mytilus edulis): integrating tissue and organism response.

Increased maintenance costs at cellular, and consequently organism level, are thought to be involved in shaping the sensitivity of marine calcifiers to ocean acidification (OA). Yet, knowledge of the capacity of marine calcifiers to undergo metabolic adaptation is sparse. In Kiel Fjord, blue mussels thrive despite periodically high seawater PCO 2 , making this population interesting for studying metabolic adaptation under OA. Consequently, we conducted a multi-generation experiment and compared physiological responses of F1 mussels from 'tolerant' and 'sensitive' families exposed to OA for 1 year. Family classifications were based on larval survival; tolerant families settled at all PCO 2 levels (700, 1120, 2400 µatm) while sensitive families did not settle at the highest PCO 2 (≥99.8% mortality). We found similar filtration rates between family types at the control and intermediate PCO 2 level. However, at 2400 µatm, filtration and metabolic scope of gill tissue decreased in tolerant families, indicating functional limitations at the tissue level. Routine metabolic rates (RMR) and summed tissue respiration (gill and outer mantle tissue) of tolerant families were increased at intermediate PCO 2 , indicating elevated cellular homeostatic costs in various tissues. By contrast, OA did not affect tissue and routine metabolism of sensitive families. However, tolerant mussels were characterised by lower RMR at control PCO 2 than sensitive families, which had variable RMR. This might provide the energetic scope to cover increased energetic demands under OA, highlighting the importance of analysing intra-population variability. The mechanisms shaping such difference in RMR and scope, and thus species' adaptation potential, remain to be identified.

Introduction There is sufficient evidence showing the positive effects of physical exercise on various aspects of pregnancy. This study evaluates knowledge and status of physical exercise among pregnant women. Methods The standardised paper-pencil questionnaire “Pregnancy Physical Activity Questionnaire” (PPAQ) as well as general demographic questions were used to assess the exercise behaviour of study participants. 83 questionnaires completed by women presenting to the Kiel University Hospital for antenatal assessment were included in the analysis. Results At the time of questionnaire completion 10 women were in the first trimester of pregnancy, 64 in the second, and 9 in the third. Just less than 90% of participants felt they had been informed “sufficiently” on the topic physical exercise during pregnancy, over 50% felt they were “well” or “very well” informed. Just less than half of participants received their information from a doctor (either their gynaecologist or general practitioner) and none of these felt “insufficiently” informed. Almost 80% of participants reported still doing no sport or less exercise than before falling pregnant. The maximum proportional energy expenditure for recreational activity – just under 20% – was in the third trimester. Women who felt they had been well counselled tended to have higher activity levels. Conclusion Study participants demonstrated a clear decline in physical exercise during pregnancy despite clear evidence of the benefits of regular exercise for pregnant women, and despite participants feeling they were well informed. Detailed information on the recommendations for physical exertion in pregnancy should form an integral part of antenatal counselling. PMID:28579622

Full Text Available Between 1789 and 1815 Europe was devastated by a series of intermittent Wars waged by the French. The first part came about through the French Revolution, the second, the Napoleonic Wars, were about Bonaparte’s thirst for conquest. Almost at the end of them, Denmark’s attempted neutrality was to cost her the loss of Norway by cessation to Sweden under the Treaty of Kiel in 1814. The Norwegians felt particularly aggrieved by this, a ploy on the part of the British to disarm the Scandinavians and retain British Naval access to the Baltic. Thus began a half a century of particular national insecurity for Denmark, during which she felt under constant threat from German ambition through an increasingly powerful, predatory Prussia. Schleswig-Holstein was particularly at risk of annexation, because though much of Slesvig was culturally and ethnically Danish, southern Jutland had been strongly infiltrated by German influences unchecked for many decades (Sandiford 1975: 21. With a small population (2,225,000 in 1848 and now detached from those potentially sympathetic in Scandinavia, Denmark would have difficulty effectively opposing any major industrial power. Britain and Germany aside, there was also Russia, still largely undeveloped, but a power with strong Baltic interests. Maintaining Denmark’s borders through this delicately balanced neutrality was not going to be easy for such a small nation state. Would it be remotely possible to achieve this passively by developing trade? Could enduring borders otherwise be protected by influencing perceptions of Denmark’s historic cultural identity and ethnicity?

Optimising the Number of Replicate- Versus Standard Measurements for Carbonate Clumped Isotope Thermometry

Clumped isotope measurements on carbonates are a quickly developing and promising palaeothermometry proxy1-3. Developments in the field have brought down the necessary sample amount and improved the precision and accuracy of the measurements. The developments have included inter-laboratory comparison and the introduction of an absolute reference frame4, determination of acid fractionation effects5, correction for the pressure baseline6, as well as improved temperature calibrations2, and most recently new approaches to improve efficiency in terms of sample gas usage7. However, a large-scale application of clumped isotope thermometry is still hampered by required large sample amounts, but also the time-consuming analysis. In general, a lot of time is goes into the measurement of standards. Here we present a study on the optimal ratio between standard- and sample measurements using the Kiel Carbonate Device method. We also consider the optimal initial signal intensity. We analyse ETH-standard measurements from several months to determine the measurement regime with the highest precision and optimised measurement time management.References 1. Eiler, J. M.

For single-cell or metagenomic sequencing projects, it is necessary to sequence with a very high mean coverage in order to make sure that all parts of the sample DNA get covered by the reads produced. This leads to huge datasets with lots of redundant data. A filtering of this data prior to assembly is advisable. Brown et al. (2012) presented the algorithm Diginorm for this purpose, which filters reads based on the abundance of their k-mers. We present Bignorm, a faster and quality-conscious read filtering algorithm. An important new algorithmic feature is the use of phred quality scores together with a detailed analysis of the k-mer counts to decide which reads to keep. We qualify and recommend parameters for our new read filtering algorithm. Guided by these parameters, we remove in terms of median 97.15% of the reads while keeping the mean phred score of the filtered dataset high. Using the SDAdes assembler, we produce assemblies of high quality from these filtered datasets in a fraction of the time needed for an assembly from the datasets filtered with Diginorm. We conclude that read filtering is a practical and efficient method for reducing read data and for speeding up the assembly process. This applies not only for single cell assembly, as shown in this paper, but also to other projects with high mean coverage datasets like metagenomic sequencing projects. Our Bignorm algorithm allows assemblies of competitive quality in comparison to Diginorm, while being much faster.

Between January 1986 and August 1993, 63 patients with primary extranodal Non-Hodgkin lymphoma of head and neck region, stages IE and IIE were treated with radiotherapy. The histological classification followed the Kiel classification, staging the Ann Arbor classification. Patient characteristics: 33 Male, 30 female; age 18 to 84 years; tumor localisation: Tonsils 26, nasopharynx 7, oropharynx 8, paranasal sinus 11, salivary glands 7, floor of mouth/gingiva 3, larynx 1. Mean follow-up is 74 months. Low-grade lymphoma in stages I and II CS were treated with definitive radiation therapy according to the concepts of epithelial tumors of the same localisation (target volume and technique).The adjuvant dose was 30 Gy and in the tumor volume 40 Gy, 2 Gy daily. 28 patients were registered, 18 in stage I and 10 in stage II. High-grade lymphoma were treated with definitive radiation therapy according to the concepts of epithelial tumors of the same localisation, too. The dose was 40 respectively 50 Gy, followed by 4 course of adjuvant chemotherapy with CHOP. Thirty-five patients were enrolled, of whom only 10 received chemotherapy. The overall 5-year survical rates were for low-grade 67% and for high grade lymphoma 88%. The corresponding relapse-free survival rates were 54/68%, respectively. Only 1 patient failed within the irradiated target volume. Recurrences occurred at sites distant to the irradiated volume in nodal and extranodal regions. Prognosis was influenced by histologic grade. Significant trends were not observed for other potential pretreatment parameters (age, stage, localisation, bulk). (orig./MG) [de

The propagation of cosmic rays in turbulent magnetic fields can be studied in detail by way of in-situ measurements of energetic particles in the three-dimensional heliosphere. Measurements of 3-20 MeV electrons from 1990 to 2003 have been made by the Kiel Electron Telescope (KET) onboard the Ulysses spacecraft during varying solar conditions. In order to interpret these measurements, it is necessary to distinguish between solar, galactic and Jovian electrons and to investigate their propagation, by using sophisticated particle propagation models. The solar contribution to the MeV electron intensities can be excluded by analyzing the electron energy spectra and the nuclei time histories. The residual electron intensities can be reasonably described by modulation models taking into account galactic cosmic rays as well as Jovian electrons using different diffusion coefficients for solar minimum and maximum. The way in which the relative contribution of Jovian (point source in the ecliptic) and galactic electrons (isotropic source) varies along the Ulysses orbit is strongly dependent on the choice of these coefficients. Since the 1970's quiet time electron increases have been observed in the ecliptic and interpreted as Jovian electron increases. Therefore, the occurrence of such quiet time electron increases is an indicator for a dominant Jovian contribution to the measured MeV electron intensities. At solar minimum and maximum such events have been observed up to ∼30 deg. and ∼45 deg. These observations are crucial for a determination of the diffusion parameters. At solar maximum a more efficient latitude transport is needed to account for the electron intensity variations

B. Blank1, H. Hu1, W. van der Wal1, F Pappa2, J. Ebbing21Delft University of Technology 2Christian-Albrechts-University of KielSince the beginning of the 2000's time-variable gravity data from GRACE has proved to be an effective method for mapping ice mass loss in Antarctica. However, Glacial Isostatic Adjustment (GIA) models are required to correct for GIA induced mass changes. While most GIA models have adopted an Earth model that only varies radially in parameters, it has long been clear that the Earth structure also varies with longitude and latitude. For this study a new global 3D GIA model has been developed within the finite element software package ABAQUS, which can be modified to operate on a spatial resolution down to 50 km locally. The model is being benchmarked against normal model models for surface loading. It will be used to investigate the effects of a 3D varying lithosphere and upper asthenosphere in Antarctica. Viscosity which will be computed from temperature estimates with laboratory based flow laws. A new 3D temperature map of the Antarctic lithosphere has been developed within ESA's GOCE+ project based on seismic data as well as on GOCE and GRACE inferred gravity gradients. Output from the GIA model with this new temperature estimates will be compared to that of 1D viscosity profiles and other recent 3D viscosity models based on seismic data. From these side to side comparisons we want to investigate the influence of the viscosity map on uplift rates and horizontal movement. Finally the results can be compared to GPS measurement to investigate the validity of all models.

Latitudinal and radial variation of >2 GeV/n protons and alpha-particles at solar maximum: ULYSSES COSPIN/KET and neutron monitor network observations

Full Text Available Ulysses, launched in October 1990, began its second out-of-ecliptic orbit in September 1997. In 2000/2001 the spacecraft passed from the south to the north polar regions of the Sun in the inner heliosphere. In contrast to the first rapid pole to pole passage in 1994/1995 close to solar minimum, Ulysses experiences now solar maximum conditions. The Kiel Electron Telescope (KET measures also protons and alpha-particles in the energy range from 5 MeV/n to >2 GeV/n. To derive radial and latitudinal gradients for >2 GeV/n protons and alpha-particles, data from the Chicago instrument on board IMP-8 and the neutron monitor network have been used to determine the corresponding time profiles at Earth. We obtain a spatial distribution at solar maximum which differs greatly from the solar minimum distribution. A steady-state approximation, which was characterized by a small radial and significant latitudinal gradient at solar minimum, was interchanged with a highly variable one with a large radial and a small – consistent with zero – latitudinal gradient. A significant deviation from a spherically symmetric cosmic ray distribution following the reversal of the solar magnetic field in 2000/2001 has not been observed yet. A small deviation has only been observed at northern polar regions, showing an excess of particles instead of the expected depression. This indicates that the reconfiguration of the heliospheric magnetic field, caused by the reappearance of the northern polar coronal hole, starts dominating the modulation of galactic cosmic rays already at solar maximum.Key words.

The knowledge of loads and concentrations is fundamental for the design of graywater treatment units, but the data on the characteristics of graywater and in particular graywater solids are weak. As general design values regarding graywater treatment facilities are not available for Germany, the objective of this article is to elaborate the characteristics of graywater and graywater solids. This paper describes the results of six sampling campaigns carried out on graywater systems in the German cities Berlin, Lübeck and Kiel. All graywater samples were collected proportional to the flow and the graywater solids were gathered separately. The collected data include graywater volumes and characteristics regarding the organic pollution (chemical oxygen demand (COD), 5-day biochemical oxygen demand (BOD 5 )) and nutrients (total nitrogen (TN), total phosphorus (TP)). The graywater volume fluctuated depending on the location. The specific average flow was 68 litre per inhabitant per day (L/inh.d). Inhabitant-specific loads of 49.3 gCOD t /inh·d, 28 gBOD 5 /inh.d, 1 gTN t /inh.d and 0.38 gTP t /inh.d (subscript 't' = total) were found. Information about the composition of graywater solids in terms of quantity and quality is seriously lacking. Therefore, graywater solids were examined with respect to organic matter (COD) and nutrients (TN, TP). The contribution of graywater solids with particle sizes over 200 microns in relation to the total inhabitant-specific load was approximately 3-8% depending on the parameter. The qualitative and quantitative characteristics of the investigated graywater fractions may serve as a base for the estimation of design values.

The rotational spectrum of (CH3OH)2 has been observed in the region 4-22 GHz with pulsed-beam Fabry-Perot cavity Fourier-transform microwave spectrometers at NIST and at the University of Kiel. Each a-type R(J), Ka = 0 transition is split into 15 states by tunneling motions for (CH3OH)2, (13CH3OH)2, (CH3OD)2, (CD3OH)2, and (CD3OH)2. The preliminary analysis of the methyl internal rotation presented here was guided by the previously developed multidimensional tunneling theory which predicts 16 tunneling components for each R(J) transition from 25 distinct tunneling motions. Several isotopically mixed dimers of methanol have also been measured, namely 13CH3OH, CH3OD, CD3OH, and CD3OD bound to 12CH3OH. Since the hydrogen bond interchange motion (which converts a donor into an acceptor) would produce a new and less favorable conformation from an energy viewpoint, it does not occur and only 10 tunneling components are observed for these mixed dimers. The structure of the complex is similar to that of water dimer with a hydrogen bond distance of 2.035 Å and a tilt of the acceptor methanol of 84° from the O-H-O axis. The effective barrier to internal rotation for the donor methyl group of (CH3OH)2 is ν3 = 183.0 cm-1 and is one-half of the value for the methanol monomer (370 cm-1), while the barrier to internal rotation of the acceptor methyl group is 120 cm-1.

The GEOMAR Helmholtz Centre for Ocean Research Kiel is currently developing a Imagenex Delta T based lander system for monitoring and quantifying marine gas release (bubbles). The GasQuant II is built as the successor of the GasQuant I system (Greinert, 2008), that has been successfully used for monitoring tempo-spatial variability of gas release in the past (Schneider von Deimling et al., 2010). The new system is lightweight (40 kg), energy efficient, flexible to use and built for ROV deployment with autonomous operation of up to three days. A prototype has been successfully deployed in Eckernförde Bay during the R/V ALKOR cruise AL447 in October/November 2014 to monitor the tempo-spatial variability of gas bubble seepage and to detect a possible correlation with tidal variations. Two deployments, one in forward- and one in upward looking mode, reveal extensive but scattered single bubble releases rather than distinct and more continuous sources. While these releases are difficult to detect in forward looking mode, they can unambiguously be detected in the upward looking mode even for minor gas releases, bubble rising speeds can be determined.

The Greenland ice sheet forms a key factor controlling the Quaternary-style glacial scenario. However, origin and mechanisms of major Arctic glaciation starting at 3.15 Ma and culminating at 2.74 Ma have remained controversial. For this phase of intense cooling Ravelo et al. (2004) proposed a complex gradual forcing mechanism. In contrast, our new submillennial-scale paleoceanographic records from the Pliocene North Atlantic suggest a far more precise timing and forcing for the initiation of northern hemisphere glaciation (NHG), since it was linked to a 2-3 /degC surface water warming during warm stages from 2.95 to 2.82 Ma (until glacial stage G10). These records support previous models (Haug and Tiedemann, 1998) claiming that the final closure of the Panama Isthmus (3.0 - ~2.5 Ma; Groeneveld, 2005) induced an increased poleward salt and heat transport. Associated strengthening of North Atlantic thermohaline circulation and in turn, an intensified moisture supply to northern high latitudes resulted in the build-up of NHG, finally culminating in the great, irreversible climate crash at glacial stage G6 (2.74 Ma). In summary, we see a two-step threshold mechanism that marked the onset of NHG with glacial-to-interglacial cycles quasi-persistent until today.

To obtain more data, we performed a clinical cohort pilot study about the influence of pollen on AE between sensitized and nonsensitized subjects and an experimental study addressing the cutaneous penetration of pollen into the skin. Fifty-five patients were monitored during birch pollen season. To study the cutaneous penetration, grass pollen allergens were applied on excised skin and the uptake in CD1c-expressing dendritic cells was investigated. The correlation between environmental pollen load and severity of the Scoring Atopic Dermatitis (SCORAD score and pruritus was observed, regardless of the status of sensitization. The sensitized group recovered significantly worse after the birch pollen season. Remarkably higher amounts of pollen allergens taken up by CD1c cells were detected in epidermal cells derived from skin explants with a disturbed epidermal barrier. These findings suggest an exacerbating role of pollen in AE utilizing the epidermal route.

Merkel cell carcinoma (MCC) is a malignant neuroendocrine skin tumor frequently associated with the Merkel cell polyomavirus. Immune checkpoint therapy showed remarkable results, although not all patients are responsive to this therapy. Anti-tropomyosin receptor kinase A (TrkA)-targeted treatment has shown promising results in several tumor entities. To determine TrkA expression in MCC as a rationale for potential targeted therapy. This case series study investigated the MCC specimens of 55 patients treated at the Department of Dermatology, University Hospital of Schleswig-Holstein, Kiel, Germany, from January 1, 2005, through December 31, 2015. Thirty-nine of the 55 samples were suitable for further histopathologic examination. Expression of TrkA was explored by immunohistochemical analysis. Diagnosis of MCC was confirmed by staining positive for cytokeratin 20 (CK20) and synaptophysin. Expression of TrkA on the tumor cells. Specimens of 39 patients (21 women and 18 men; mean [SD] age, 75.0 [7.8] years) underwent immunohistochemical investigation. Thirty-eight of 38 specimens expressed CK20 and synaptophysin on the MCC tumor cells (100% expression). Merkel cell polyomavirus was detected in 32 of 38 specimens (84%). Tropomyosin receptor kinase A was found in all 36 evaluable specimens on the tumor cells; 34 (94%) showed a weak and 2 (6%) showed a strong cytoplasmic expression. In addition, strongly positive perinuclear dots were observed in 30 of 36 specimens (83%). Tropomyosin receptor kinase A was expressed on MCC tumor cells in 100% of evaluable specimens. This result may lead to the exploration of new targeted treatment options in MCC, especially for patients who do not respond to anti-programmed cell death protein 1 treatment.

In the center stage of this third and last part of the author's treatise about the life and the oeuvre of the German humanist, biochemist, and Nobel Prize Winner Otto MEYERHOF (1884-1951) is the first half of his life. As a young man, in the age of 16 and after a severe renal disease, Otto MEYERHOF spent 1900/1901 five months in Egypt, where he, led by his cousin Max MEYERHOF, Egyptologist and Ophthalmologist, studied the country and its people as well as its architecture and history. During his medical courses he became acquainted with the philosopher Leonard NELSON, who stimulated him to study the Kantian-Friesian philosophy, about which he published several papers. Simultaneously MEYERHOF became seriously interested in GOETHE'S method of natural investigation. About this topic he gave two famous lectures, 1909 in Berlin and 1949 in his American exile in New York. From 1903 MEYERHOF attended medical courses and conducted advanced training courses for workers at the University of Berlin. 1907 in the Heidelberg philosophical circle MEYERHOF became acquainted with Otto WARBURG. 1909 MEYERHOF earned a doctorate in medicine with the thesis "Contributions to a psychological theory of mental disorders". In the years 1911/12 a deep change occurred in MEYERHOF'S scientific career, in the course of which he turned to active experimental research in natural science. However, MEYERHOF remained true to philosophy and his friendship to Leonard NELSON. When Otto MEYERHOF in 1911 obtained a Badian scholarship for experimental research work in the Zoological Station in Naples, a tight collaboration with Otto WARBURG in sea urchin egg biology began. In 1912 MEYERHOF published a famous paper on "The energetics of cellular processes", which became the guideline for his prospective scientific work. In the same year he habilitated at the Medical School of the Kiel University with an enzymological study, and he joined the Physiological Institute of Kiel as unpaid private lecturer

Sedimentology and stratigraphy of the middle Eocene Guara carbonate platform near Arguis, South-West Pyrenean foreland: Implications for basin physiography

the paleobathymetric gradient on this side of the foreland basin. The sedimentological and paleontological content show that the Guara formation was deposited in shallow water environments (less than 80 m) and can be classified as a carbonate ramp. The evolution of paleobathymetries with time on these two sections allows us to identify three complete progradational - retrogradational cycles. Those cycles do not match global eustatic variations, perhaps indicating the dominating influence of tectonics in this area. The precise study of foraminifera allowed us to date our sections with respect to the SBZ time scale of Serra-Kiel et al. (1). The bottom of the Guara formation, in the Arguis section is dated from the lower Lutetian (SBZ 13) and the top corresponds to the upper Lutetian (SBZ 16). An important hiatus is recorded between the base of the carbonates and the lower Paleocene subjacent continental deposits. Moreover, the base of the formation is older at Lusera i.e. to the centre of the basin. This hiatus could thus represent the foreland flexural forebulge unconformity (2). By restoring the relative position of the two sections during the Lutetian, we have calculated the possible slope of the Guara ramp during this period for each MFS, with values always lower than 0.5°. Extrapolating this slope to the centre of the basin allows us to estimate the paleodepth of the coeval Eocene turbidites and address the important issue of the depth of deposition of submarine fan systems in foreland settings. Within the limits of our approach we propose that these clastic fan systems have been deposited under water depths of 400 to 200 metres. This is partly in agreement with the upper bound of other estimations based on foraminiferal assemblages and trace fossils, and thus favours a relatively "shallow" view of the Middle Eocene Ainsa-Jaca deep marine basin. 1.

To determine age-related associations between fat mass (FM), regional fat depots and cardiometabolic traits in normal- and overweight children, adolescents and adults. Detailed body composition (regional subcutaneous and visceral adipose tissue; SAT, VAT) by whole-body magnetic resonance imaging (MRI), FM and fat-free mass by air-displacement plethysmography, systolic and diastolic blood pressure (SBP, DBP), triglycerides (TG), high-density lipoprotein cholesterol (HDL), plasma glucose and plasma insulin were measured in 433 subjects (BMI: 23.6 (21.0-27.7); 151 children and adolescents, aged 6-18 years, 150 young adults, aged 18-30 years and 132 adults, aged 30-60 years). Data were derived from pooled data of the 'Reference Center for Body Composition' in Kiel, Germany. Insulin resistance was determined by the homeostatic model assessment of insulin resistance (HOMA-IR). Partial correlations and multivariate linear regression analyses were used to evaluate the associations between body composition and cardiometabolic traits. A descriptive approach was used to demonstrate age-dependent differences in associations between body fat depots and insulin resistance, independent of BMI. FM, SAT, and VAT increased from childhood to adulthood with low VAT in children and adolescents. When compared to children, TG was higher in adults. HDL and DBP did not differ between age groups. Insulin resistance was highest in male adolescents and female young adults. Associations between body fat depots and cardiometabolic traits were seen after puberty with no associations in pre- and intrapubertal children. When compared to FM, SAT and VAT had the strongest association with insulin resistance in adults. This association was independent of BMI. Associations between individual body fat depots and most cardiometabolic traits became evident after puberty only. The strongest associations were observed between insulin resistance and abdominal fat in adults. The impact of VAT was independent

"Searching for plastic garbage" is an international Citizen Science project that aims to participate school students in the public discussion on the topic "plastic pollution in the ocean". For this, young people apply various research methods, evaluate their data, communicate and publish their results and investigate solutions solving this problem. The project will be carried out in Chile and Germany at the same time, which allows the participating students to share and compare their results and discuss their ideas with an international partner. This takes place on the website www.save-ocean.org. The project promotes intercultural and scientific skills of the students. They get insights into scientific research, get into another culture and experiences plastic pollution as an important global problem. Since May 2015, 450 pupils aged 10 to 15 years and 20 teachers in Germany and Chile have explored the plastic garbage on beaches. Where are the largest plastic garbage deposits? Which items of plastic are mostly found in Germany and Chile? Or where does this garbage comes from? These and other research questions are being answered by an international network between students, teachers and scientists. After completing the first Citizen Science pilot study successfully in summer 2015, the entire German and Chilean coast will be explored in spring 2016 by around 2500 participating school students. The project "Searching for plastic garbage" is the first international Citizen Science project that is a cooperation between the ocean:lab of Kiel Science Factory and the "Cientificos de la Basura", a project of the department of marine biology at University Catolica del Norte in Coquimbo, Chile. The project is supported by the Cluster of Excellence "The Future Ocean", the Leibniz Institute for Science Education and Mathematics (IPN), the Ministry of School and Professional Education of Land Schleswig-Holstein and the University Catolica del Norte in Coquimbo, Chile

In adults, exercise blood pressure seems to be more closely related to cardiovascular risk than resting blood pressure; however, few data are available on the effects of familial risk factors, including smoking habits, on exercise blood pressure in adolescents. Blood pressure at rest and during exercise, parental smoking, and other familial risk factors were investigated in 532 adolescents aged 12 to 17 years (14.6±1.5 years) in the Kiel EX.PRESS. (EXercise PRESSure) Study. Exercise blood pressure was determined at 1.5 W/kg body weight using a standardized submaximal cycle ergometer test. Mean resting blood pressure was 113.1±12.8/57.2±7.1 mm Hg, and exercise blood pressure was 149.9±19.8/54.2±8.6 mm Hg. Parental smoking increased exercise systolic blood pressure (+4.0 mm Hg, 3.1 to 4.9; P=0.03) but not resting blood pressure of the subjects (adjusted for age, sex, height, body mass index percentile, fitness). Parental overweight and familial hypertension were related to both higher resting and exercise systolic blood pressure values, whereas associations with an inactive lifestyle and a low educational level of the parents were found only with adolescents' blood pressure during exercise. The cumulative effect of familial risk factors on exercise systolic blood pressure was more pronounced than on blood pressure at rest. Parental smoking might be a novel risk factor for higher blood pressure, especially during exercise. In addition, systolic blood pressure during a submaximal exercise test was more closely associated with familial risk factors than was resting blood pressure, even in adolescents. © 2015 The Authors.

Full Text Available Background: Evaluation of anti-mullerian hormone (AMH cut-off levels in assisted reproductive technology (ART as predictive factor for individualization of stimulation protocols and to avoid ovarian hyperstimulation syndrome (OHSS. Materials and Methods: In a retrospective study, 177 infertile patients were assessed for AMH in serum and follicular fluid (FF on the day of follicular puncture (FP, between 2012 and 2013 in Kiel, Germany. AMH levels and pregnancy rates were compared between low, moderate and high responders and cut-off levels of low and high responders. AMH cut-off levels in pathological cases were evaluated in analysis 1 (OHSS and in analysis 2 [polycystic ovarian syndrome, (PCOS] and compared in analysis 3 to normal endocrinological parameters. Results: AMH levels in FF were higher than in serum (P<0.001. AMH levels in serum and FF increased from low through moderate to high responders (P<0.001. Pregnancy rates were 14.7, 23.3 and 44.9% (P=0.009, respectively. AMH cut-off level for poor responders was 0.61 ng/ml in serum with a pregnancy rate of 13.8 and 37.1% for below and above of this level, respectively. For FF, it was 1.43 ng/ml. AMH levels in analysis 1 and 2 were significantly higher than in analysis 3 (P=0.001. AMH cut-off level for OHSS was 1.5 ng/ml in serum with OHSS rates of 80.8 and 19.2 % for above and below of the level, respectively. For FF, it was 2.7 ng/ml. PCOS patients had an AMH cut-off level of 3.9 ng/ml in serum and 6.8 ng/ml in FF, resulting in a PCOS rate of 100% above this level. Conclusion: AMH levels can help to assess ovarian response potential and guide ovarian stimulation while avoiding OHSS.

Here, we targeted EGFR on the ovarian carcinoma cell line OVCAR-3 with AuNPs. In order to optimize membrane permeability and to demonstrate molecule delivery into adherent OVCAR-3 cells, we systematically investigated different experimental conditions. Materials and methods: AuNPs (30 nm were functionalized by conjugation of the antibody cetuximab against EGFR. Selective binding of the particles was demonstrated by silver staining, multiphoton imaging, and fluorescence-lifetime imaging. After laser irradiation, membrane permeability of OVCAR-3 cells was studied under different conditions of AuNP concentration, cell-incubation medium, and cell–AuNP incubation time. Membrane permeability and cell viability were evaluated by flow cytometry, measuring propidium iodide and fluorescein isothiocyanate–dextran uptake. Results: Adherently growing OVCAR-3 cells can be effectively targeted with EGFR-AuNP. Laser irradiation led to successful permeabilization, and 150 kDa dextran was successfully delivered into cells with about 70% efficiency. Conclusion: Antibody-targeted and laser-irradiated AuNPs can be used to deliver molecules into adherent cells. Efficacy depends not only on laser parameters but also on AuNP:cell ratio, cell-incubation medium

Discrimination of Parkinsonian Tremor From Essential Tremor by Voting Between Different EMG Signal Processing Techniques

Directory of Open Access Journals (Sweden)

A Hossen

2014-06-01

Full Text Available Parkinson's disease (PD and essential tremor (ET are the two most common disorders that cause involuntary muscle shaking movements, or what is called "tremor”. PD is a neurodegenerative disease caused by the loss of dopamine receptors which control and adjust the movement of the body. On the other hand, ET is a neurological movement disorder which also causes tremors and shaking, but it is not related to dopamine receptor loss; it is simply a tremor. The differential diagnosis between these two disorders is sometimes difficult to make clinically because of the similarities of their symptoms; additionally, the available tests are complex and expensive. Thus, the objective of this paper is to discriminate between these two disorders with simpler, cheaper and easier ways by using electromyography (EMG signal processing techniques. EMG and accelerometer records of 39 patients with PD and 41 with ET were acquired from the Hospital of Kiel University in Germany and divided into a trial group and a test group. Three main techniques were applied: the wavelet-based soft-decision technique, statistical signal characterization (SSC of the spectrum of the signal, and SSC of the amplitude variation of the Hilbert transform. The first technique resulted in a discrimination efficiency of 80% on the trial set and 85% on the test set. The second technique resulted in an efficiency of 90% on the trial set and 82.5% on the test set. The third technique resulted in an 87.5% efficiency on the trial set and 65.5% efficiency on the test set. Lastly, a final vote was done to finalize the discrimination using these three techniques, and as a result of the vote, accuracies of 92.5%, 85.0% and 88.75% were obtained on the trial data, test data and total data, respectively.

Fernandes, R. C.; Lucio, P. S.; Fernandez, J. H.

2017-05-01

The occurrence of missing data concerning Galactic Cosmic Rays time series (GCR) is inevitable since loss of data is due to mechanical and human failure or technical problems and different periods of operation of GCR stations. The aim of this study was to perform multiple dataset imputation in order to depict the observational dataset. The study has used the monthly time series of GCR Climax (CLMX) and Roma (ROME) from 1960 to 2004 to simulate scenarios of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80% and 90% of missing data compared to observed ROME series, with 50 replicates. Then, the CLMX station as a proxy for allocation of these scenarios was used. Three different methods for monthly dataset imputation were selected: AMÉLIA II - runs the bootstrap Expectation Maximization algorithm, MICE - runs an algorithm via Multivariate Imputation by Chained Equations and MTSDI - an Expectation Maximization algorithm-based method for imputation of missing values in multivariate normal time series. The synthetic time series compared with the observed ROME series has also been evaluated using several skill measures as such as RMSE, NRMSE, Agreement Index, R, R2, F-test and t-test. The results showed that for CLMX and ROME, the R2 and R statistics were equal to 0.98 and 0.96, respectively. It was observed that increases in the number of gaps generate loss of quality of the time series. Data imputation was more efficient with MTSDI method, with negligible errors and best skill coefficients. The results suggest a limit of about 60% of missing data for imputation, for monthly averages, no more than this. It is noteworthy that CLMX, ROME and KIEL stations present no missing data in the target period. This methodology allowed reconstructing 43 time series.

The river impoundment by The Three Gorges Dam leads to resettlement and land reclamation on steep slopes. As a consequence, ecosystem changes such as soil erosion, mass movements, and diffuse sediment and matter fluxes are widely expected to increase rapidly. In order to assess and analyse those ecosystem changes, the German-Chinese joint research project YANGTZE-GEO was set up in 2008. Within the framework of YANGTZE-GEO five German universities (Tuebingen, Erlangen, Giessen, Kiel, Potsdam) conducted studies on soil erosion, mass movements, diffuse matter inputs, and land use change and vulnerability in close collaboration with Chinese scientists. The Chinese partners and institutions are according to their alphabetic order of hometown the Chinese Research Academy of Environmental Sciences (CRAES; Beijing), the Standing Office of the State Council Three Gorges Project Construction Committee (Beijing), the National Climate Centre (NCC) of the China Meteorological Administration (CMA; Beijing), the Aero Geophysical Survey and Remote Sensing for Land and Resources (AES; Beijing), the Nanjing University, the CAS Institute of Soil Science (Nanjing), the Nanjing Institute of Geography and Limnology at CAS (NIGLAS; Nanjing), the China University of Geosciences (CUG; Wuhan), the CAS Institute of Hydrobiology (Wuhan), and the China Three Gorges University (Yichang). The overall aim of YANGTZE-GEO is the development of a risk assessment and forecasting system to locate high risk areas using GIS-based erosion modelling, data mining tools for terrace condition analysis and landslide recognition, eco-hydrological modelling for diffuse matter inputs, and state-of-the-art remote sensing to assess the landscape's vulnerability. Furthermore, the project aims at the recommendation of sustainable land management systems. YANGTZE-GEO showed the relevance of such research and crucially contributes to the understanding of the dimension and dynamics of the ecological consequences of

Within the framework of the project a conceptional soil map for the urban area of Rostock was drawn up. The starting point was formed by the collection and analysis of available information. The following maps were digitised with the help of the geographical information system Arc/Info: Soil estimation, middle scaled map of agricultural sites, geology, maps of bogs and forest sites, map of the bog-depth sourrounding the river Warnow by Geinitz from 1887. To characterise the influence by man information about impermeable covered areas, actual land use, thrown up areas and disposal sites as well as war-destroyed sites were digitally used. Till the beginning of this project no information about impermeable covered areas and about the actual land use were available. That's why these two maps were created within the framework of the project on the base of topographical maps, aerial photographs and results of on-site-captures. Afterwards the thematic layers were overlapped. The general conceptional map for the urban area of Rostock was created out of the three separate conceptional maps about groundwater-influence, natural soil inventory and man-influence. Soil societies were assigned to the units of this general conceptional map. At the end 35 units were given for Rostock. Detailed mappings were taken on areas of the following kinds of use: Living areas, city centre, gardens, parks, graveyards, industrial and military sites. 26 main profiles were described and soil-physically and soil-chemically examined. The total contents of the heavy metals Zn, Cu, Pb and Cd were determined for the horizons of the main profiles. The subproject of Rostock is also concerned with investigations on the heavy metals (hM) Cu, Pb, Cd, Zn and Ni in technological substrates (tS) from Kiel, Eckernfoerde, Halle and Rostock (11 main soil profiles).

Lack of genomic evidence of AI-2 receptors suggests a non-quorum sensing role for luxS in most bacteria.

Great excitement accompanied discoveries over the last decade in several Gram-negative and Gram-positive bacteria of the LuxS protein, which catalyzes production of the AI-2 autoinducer molecule for a second quorum sensing system (QS-2). Since the luxS gene was found to be widespread among the most diverse bacterial taxa, it was hypothesized that AI-2 may constitute the basis of a universal microbial language, a kind of bacterial Esperanto. Many of the studies published in this field have drawn a direct correlation between the occurrence of the luxS gene in a given organism and the presence and functionality of a QS-2 therein. However, rarely hathe existence of potential AI-2 receptors been examined. This is important, since it is now well recognized that LuxS also holds a central role as a metabolic enzyme in the activated methyl cycle which is responsible for the generation of S-adenosyl-L-methionine, the major methyl donor in the cell. In order to assess whether the role of LuxS in these bacteria is indeed related to AI-2 mediated quorum sensing we analyzed genomic databases searching for established AI-2 receptors (i.e., LuxPQ-receptor of Vibrio harveyi and Lsr ABC-transporter of Salmonella typhimurium) and other presumed QS-related proteins and compared the outcome with published results about the role of QS-2 in these organisms. An unequivocal AI-2 related behavior was restricted primarily to organisms bearing known AI-2 receptor genes, while phenotypes of luxS mutant bacteria lacking these genes could often be explained simply by assuming deficiencies in sulfur metabolism. Genomic analysis shows that while LuxPQ is restricted to Vibrionales, the Lsr-receptor complex is mainly present in pathogenic bacteria associated with endotherms. This suggests that QS-2 may play an important role in interactions with animal hosts. In most other species, however, the role of LuxS appears to be limited to metabolism, although in a few cases the presence of yet unknown

How does global biogeochemical cycle become complicated by terrestrial-aquatic interactions ?

Inland water such as river and lake are now known to be important and active components of global carbon cycle though its contribution has remained uncertain due to data scarcity (Battin et al., 2009; Aufdenkampe et al., 2011). The author has developed process-based National Integrated Catchment-based Eco-hydrology (NICE) model (Nakayama, 2008a-b, 2010, 2011a-b, 2012a-c, 2013; Nakayama and Fujita, 2010; Nakayama and Hashimoto, 2011; Nakayama and Shankman, 2013a-b; Nakayama and Watanabe, 2004, 2006, 2008a-b; Nakayama et al., 2006, 2007, 2010, 2012), which incorporates surface-groundwater interactions, includes up- and down-scaling processes between local-global scales, and can simulate iteratively nonlinear feedback between hydrologic, geomorphic, and ecological processes. In this study, NICE was coupled with various biogeochemical models to incorporate biogeochemical cycle including reaction between inorganic and organic carbons (DOC, POC, DIC, pCO2, etc.) in terrestrial and aquatic ecosystems including surface water and groundwater. The coupled model simulated CO2 evasion from inland water in global scale, was relatively in good agreement in that estimated by empirical regression model (Raymond et al., 2013). In particular, the simulated result implied importance of connectivity between terrestrial and aquatic ecosystems in addition to surface and groundwater, and hillslopes and stream channels, etc. The model further improved the accuracy of CH4 flux in wetland which is sensitive to fluctuations of shallow groundwater because the original NICE incorporates 3-D groundwater sub-model and simulates lateral subsurface flow more reasonably. This simulation system would play important role in integration of greenhouse gas budget of the biosphere, quantification of hot spots in boundless biogeochemical cycle, and bridging gap between top-down and bottom-up approaches (Cole et al., 2007; Frei et al., 2012; Kiel and Cardenas, 2014).

Distribution of N2O in the Baltic Sea during transition from anoxic to oxic conditions

2006-01-01

Full Text Available In January 2003, a major inflow of cold and oxygen-rich North Sea Water terminated an ongoing stagnation period in parts of the central Baltic Sea. In order to investigate the role of North Sea Water inflow in the production of nitrous oxide (N2O, we measured dissolved and atmospheric N2O at 26 stations in the southern and central Baltic Sea in October 2003. At the time of our cruise, water renewal had proceeded to the eastern Gotland Basin, whereas the western Gotland Basin was still unaffected by the inflow. The deep water renewal was detectable in the distributions of temperature, salinity, and oxygen concentrations as well as in the distribution of the N2O concentrations: Shallow stations in the Kiel Bight and Pomeranian Bight were well-ventilated with uniform N2O concentrations near equilibrium throughout the water column. In contrast, stations in the deep basins, such as the Bornholm and the Gotland Deep, showed a clear stratification with deep water affected by North Sea Water. Inflowing North Sea Water led to changed environmental conditions, especially enhanced oxygen (O2 or declining hydrogen sulphide (H2S concentrations, thus, affecting the conditions for the production of N2O. Pattern of N2O profiles and correlations with parameters like oxygen and nitrate differed between the basins. Because of the positive correlation between ΔN2O and AOU in oxic waters the dominant production pathway seems to be nitrification rather than denitrification. Advection of N2O by North Sea Water was found to be of minor importance. A rough budget revealed a significant surplus of in situ produced N2O after the inflow. However, due to the permanent halocline, it can be assumed that the N2O produced does not reach the atmosphere. Hydrographic aspects therefore are decisive factors determining the final release of N2O produced to the atmosphere.

Full Text Available Warming and acidification of the oceans as a consequence of increasing CO2-concentrations occur at large scales. Numerous studies have shown the impact of single stressors on individual species. However, studies on the combined effect of multiple stressors on a multi-species assemblage, which is ecologically much more realistic and relevant, are still scarce. Therefore, we orthogonally crossed the two factors warming and acidification in mesocosm experiments and studied their single and combined impact on the brown alga Fucus vesiculosus associated with its natural community (epiphytes and mesograzers in the Baltic Sea in all seasons (from April 2013 to April 2014. We superimposed our treatment factors onto the natural fluctuations of all environmental variables present in the Benthocosms in so-called delta-treatments. Thereby we compared the physiological responses of F. vesiculosus (growth and metabolites to the single and combined effects of natural Kiel Fjord temperatures and pCO2 conditions with a 5 °C temperature increase and/or pCO2 increase treatment (1100 ppm in the headspace above the mesocosms. Responses were also related to the factor photoperiod which changes over the course of the year. Our results demonstrate complex seasonal pattern. Elevated pCO2 positively affected growth of F. vesiculosus alone and/or interactively with warming. The response direction (additive, synergistic or antagonistic, however, depended on season and daylength. The effects were most obvious when plants were actively growing during spring and early summer. Our study revealed for the first time that it is crucial to always consider the impact of variable environmental conditions throughout all seasons. In summary, our study indicates that in future F. vesiculosus will be more affected by detrimental summer heat-waves than by ocean acidification although the latter consequently enhances growth throughout the year. The mainly negative influence of rising

Quemadura es la lesión producida en los tejidos por la acción corta o prolongada de agresiones tísicas o químicas en sus diversas manifestaciones.

La variedad de formas en la agresión a los tejidos se encierra en una multiplicidad de manifestaciones, que en el mundo actual aumenta la estadística de los quemados.
El tratamiento local de las quemaduras sólo debe comenzar cuando se ha iniciado el tratamiento general contra el shock.

Después de la Segunda Guerra Mundial, y gracias a Wallace, se difundió con éxito la terapéutica del método abierto o expuesto en el tratamiento de las quemaduras al observar que tratadas al aire, bajo ciertas condiciones, curaban más rápidamente que el método oclusivo.

Max Grob, Cirujano Pediatra del Hospital Infantil de Zurich, inició en 1949 el método de escarificación, llamado hoy en día de coagulación, basándose en la acción coagulante de las proteínas. Este autor hizo su primera publicación en el libro titulado "Patología Quirúrgica Infantil" en 1957.
Posteriormente, Kuhne y Kaiser, de la Universidad de Kiel, en su artículo "Problemas del Tratamiento Local de las Quemaduras" en 1966 preconizaron de nuevo este método.
En nuestro medio, Lucio Feuillet en 1960 lo utilizó en el Hospital del Centro en Barracabermeja y en 1978 en el Hospital de la Cruz Roja de Manizales fue instaurado por el Dr. Norman Ramírez y colaboradores.
El método de coagulación para el tratamiento local de las quemaduras en mano nunca antes fue indicado por estos autores...

Orbital rhabdomyosarcoma of the child: the role of PDR brachytherapy in eye preservation

International Nuclear Information System (INIS)

Kovacs, G.; Rochels, R.; Mehdorn, H.M.; Werner, J.; Wilhelm, R.; Kohr, P.; Kimmig, B. N.

Material and Methods: There were four children (8-7-5 years and(15(12)) months old) with recurrent/primary embryonal rhabdomyosarcoma treated with curative intention by peroperative PDR boost brachytherapy in combination with radio-chemotherapy and/or surgery. PDR brachytherapy according to the Kiel protocol: daily five pulses, two hours each, with 1 Gy on the reference isodose which is usually 2-3 mm close to the applicator surface. CT simulation based conformal treatment planning was carried out in each case. The implant was done intraoperatively using the free-hand plastic tube method, after a macroscopically complete excision of the tumor. Due to treatment planning individual target volume, eye with N, opticus and bone structures, as well as the applicators and other regions of interest were visualized. Manual volume optimisation was practiced and natural volumen-dose histograms were analysed in 'classic' graphic mode as well as in a special colour coded three-dimensional visualization in cine mode on the screen. One child received, three months before the recurrence was operated, 50 Gy hyperfractionated external beam radiation (2 Gy fractions) and was irradiated with 20 Gy brachytherapy in four days. The second patient received ten days after 20 Gy brachytherapy 32 Gy hyperfractionated external beam radiation. The third child (external beam treatment outside of our clinic), received conventional fractionated irradiation with 1.6 Gy fraction dose instead of a prescribed hyperfractionated external beam therapy and her brachytherapy dose was 25 Gy. At the (15(12)) months old child with primary embryonal rhabdomyosarcoma we applied 20 Gy brachytherapy and 24 Gy hyperfractionated external beam irradiation. All patients received multidrug chemotherapy according to the German Study Protocol (CWS-91). Results: Follow-up is 34, 28, 22, and 6 months for recurrent embryonal rhabdomyosarcoma patients (stand February 96). We observed at 9 months one rhabdomyosarcoma

A GIS-based 3D online information system for underground energy storage in northern Germany

We would like to present the concept and current state of development of a GIS-based 3D online information system for underground energy storage. Its aim is to support the local authorities through pre-selection of possible sites for thermal, electrical and substantial underground energy storages. Since the extension of renewable energies has become legal requirement in Germany, the underground storing of superfluously produced green energy (such as during a heavy wind event) in the form of compressed air, gas or heated water has become increasingly important. However, the selection of suitable sites is a complex task. The presented information system uses data of geological features such as rock layers, salt domes and faults enriched with attribute data such as rock porosity and permeability. This information is combined with surface data of the existing energy infrastructure, such as locations of wind and biogas stations, powerline arrangement and cable capacity, and energy distribution stations. Furthermore, legal obligations such as protected areas on the surface and current underground mining permissions are used for the process of pre-selecting sites suitable for energy storage. Not only the current situation but also prospective scenarios, such as expected growth in produced amount of energy are incorporated in the system. While the process of pre-selection itself is completely automated, the user has full control of the weighting of the different factors via the web interface. The system is implemented as an online 3D server GIS environment, so that it can easily be utilized in any web browser. The results are visualized online as interactive 3d graphics. The information system is implemented in the Python programming language in combination with current Web standards, and is build using only free and open source software. It is being developed at Kiel University as part of the ANGUS+ project (lead by Prof. Sebastian Bauer) for the federal state of

Effect of temperature rise and ocean acidification on growth of calcifying tubeworm shells (Spirorbis spirorbis): an in situ benthocosm approach

Science.gov (United States)

Ni, Sha; Taubner, Isabelle; Böhm, Florian; Winde, Vera; Böttcher, Michael E.

The calcareous tubeworm Spirorbis spirorbis is a widespread serpulid species in the Baltic Sea, where it commonly grows as an epibiont on brown macroalgae (genus Fucus). It lives within a Mg-calcite shell and could be affected by ocean acidification and temperature rise induced by the predicted future atmospheric CO2 increase. However, Spirorbis tubes grow in a chemically modified boundary layer around the algae, which may mitigate acidification. In order to investigate how increasing temperature and rising pCO2 may influence S. spirorbis shell growth we carried out four seasonal experiments in the Kiel Outdoor Benthocosms at elevated pCO2 and temperature conditions. Compared to laboratory batch culture experiments the benthocosm approach provides a better representation of natural conditions for physical and biological ecosystem parameters, including seasonal variations. We find that growth rates of S. spirorbis are significantly controlled by ontogenetic and seasonal effects. The length of the newly grown tube is inversely related to the initial diameter of the shell. Our study showed no significant difference of the growth rates between ambient atmospheric and elevated (1100 ppm) pCO2 conditions. No influence of daily average CaCO3 saturation state on the growth rates of S. spirorbis was observed. We found, however, net growth of the shells even in temporarily undersaturated bulk solutions, under conditions that concurrently favoured selective shell surface dissolution. The results suggest an overall resistance of S. spirorbis growth to acidification levels predicted for the year 2100 in the Baltic Sea. In contrast, S. spirorbis did not survive at mean seasonal temperatures exceeding 24 °C during the summer experiments. In the autumn experiments at ambient pCO2, the growth rates of juvenile S. spirorbis were higher under elevated temperature conditions. The results reveal that S. spirorbis may prefer moderately warmer conditions during their early life stages

COPD is associated with worsening airflow limitation over time and increased frequency of COPD exacerbations, leading to increased mortality and morbidity. The effects of COPD extend beyond the lungs, as multiple comorbidities may occur with COPD, including cardiovascular disease, diabetes mellitus, osteoporosis, depression, and pneumonia. COPD exacerbations are associated with a rapid worsening of baseline symptoms that requires prompt management and may necessitate hospitalization in the case of a severe episode. Patients with COPD exacerbations require urgent management of symptoms to prevent further worsening, and preventative steps may be taken to help reduce the number and frequency of future exacerbations. Roflumilast is a potent and selective inhibitor of the enzyme phosphodiesterase-4 that targets the systemic inflammation associated with COPD. Roflumilast has a variety of anti-inflammatory effects including decreasing inflammatory mediators and the expression of cell surface markers and inhibition of apoptosis. Several clinical trials evaluating roflumilast in the treatment of COPD have demonstrated significant improvements from baseline versus placebo in lung function, including increases in mean pre- and postbronchodilator forced expiratory volume in 1 second and forced vital capacity. Data suggest that roflumilast reduces moderate to

The dominant mode of interannual variability in tropical Atlantic sea surface temperatures (SSTs) is the Atlantic Niño or Zonal Mode. Akin to the El Niño-Southern Oscillation in the Pacific sector, it is able to impact the climate both of the adjacent equatorial African continent and remote regions. Due to heavy biases in the mean state climate of the equatorial-to-subtropical Atlantic, however, most state-of-the-art coupled global climate models (CGCMs) are unable to realistically simulate equatorial Atlantic variability. In this study, the Kiel Climate Model (KCM) is used to investigate the impact of a simple bias alleviation technique on the predictability of equatorial Atlantic SSTs. Two sets of seasonal forecasting experiments are performed: An experiment using the standard KCM (STD), and an experiment with additional surface heat flux correction (FLX) that efficiently removes the SST bias from simulations. Initial conditions for both experiments are generated by the KCM run in partially coupled mode, a simple assimilation technique that forces the KCM with observed wind stress anomalies and preserves SST as a fully prognostic variable. Seasonal predictions for both sets of experiments are run four times yearly for 1981-2012. Results: Heat flux correction substantially improves the simulated variability in the initialization runs for boreal summer and fall (June-October). In boreal spring (March-May), however, neither the initialization runs of the STD or FLX-experiments are able to capture the observed variability. FLX-predictions show no consistent enhancement of skill relative to the predictions of the STD experiment over the course of the year. The skill of persistence forecasts is hardly beat by either of the two experiments in any season, limiting the usefulness of the few forecasts that show significant skill. However, FLX-forecasts initialized in May recover skill in July and August, the peak season of the Atlantic Niño (anomaly correlation

Very early onset inflammatory bowel disease (VEO-IBD), IBD diagnosed at 5 years of age or younger, frequently presents with a different and more severe phenotype than older-onset IBD. We investigated whether patients with VEO-IBD carry rare or novel variants in genes associated with immunodeficiencies that might contribute to disease development. Patients with VEO-IBD and parents (when available) were recruited from the Children's Hospital of Philadelphia from March 2013 through July 2014. We analyzed DNA from 125 patients with VEO-IBD (age, 3 wk to 4 y) and 19 parents, 4 of whom also had IBD. Exome capture was performed by Agilent SureSelect V4, and sequencing was performed using the Illumina HiSeq platform. Alignment to human genome GRCh37 was achieved followed by postprocessing and variant calling. After functional annotation, candidate variants were analyzed for change in protein function, minor allele frequency less than 0.1%, and scaled combined annotation-dependent depletion scores of 10 or less. We focused on genes associated with primary immunodeficiencies and related pathways. An additional 210 exome samples from patients with pediatric IBD (n = 45) or adult-onset Crohn's disease (n = 20) and healthy individuals (controls, n = 145) were obtained from the University of Kiel, Germany, and used as control groups. Four hundred genes and regions associated with primary immunodeficiency, covering approximately 6500 coding exons totaling more than 1 Mbp of coding sequence, were selected from the whole-exome data. Our analysis showed novel and rare variants within these genes that could contribute to the development of VEO-IBD, including rare heterozygous missense variants in IL10RA and previously unidentified variants in MSH5 and CD19. In an exome sequence analysis of patients with VEO-IBD and their parents, we identified variants in genes that regulate B- and T-cell functions and could contribute to pathogenesis. Our analysis could lead to the

Atlantic Meridional Overturning Circulation response to idealized external forcing

Energy Technology Data Exchange (ETDEWEB)

Park, W.; Latif, M. [Leibniz-Institut fuer Meereswissenschaften an der Universitaet Kiel, Kiel (Germany)

2012-10-15

The response of the Atlantic Meridional Overturning Circulation (AMOC) to idealized external (solar) forcing is studied in terms of the internal (unforced) AMOC modes with the Kiel Climate Model (KCM), a coupled atmosphere-ocean-sea ice general circulation model. The statistical investigation of KCM's internal AMOC variability obtained from a multi-millennial control run yields three distinct modes: a multi-decadal mode with a period of about 60 years, a quasi-centennial mode with a period of about 100 years and a multi-centennial mode with a period of about 300-400 years. Most variance is explained by the multi-centennial mode, and the least by the quasi-centennial mode. The solar constant varies sinusoidally with two different periods (100 and 60 years) in forced runs with KCM. The AMOC response to the external forcing is rather complex and nonlinear. It involves strong changes in the frequency structure of the variability. While the control run depicts multi-timescale behavior, the AMOC variability in the experiment with 100 year forcing period is channeled into a relatively narrow band centered near the forcing period. It is the quasi-centennial AMOC mode with a period of just under 100 years which is excited, although it is heavily damped in the control run. Thus, the quasi-centennial mode retains its period which does not correspond exactly to the forcing period. Surprisingly, the quasi-centennial mode is also most strongly excited when the forcing period is set to 60 years, the period of the multi-decadal mode which is rather prominent in the control run. It is largely the spatial structure of the forcing rather than its period that determines which of the three internal AMOC modes is excited. The results suggest that we need to understand the full modal structure of the internal AMOC variability in order to understand the circulation's response to external forcing. This could be a challenge for climate models: we cannot necessarily expect that the

The Western Mediterranean (WM) seismic network started in 1996 as an initiative of the Royal Spanish Navy Observatory (ROA) and the Universidad Complutense de Madrid (UCM), with the collaboration of the GeoForschungsZentrum (GFZ) of Potsdam. A first broad band seismic station (SFUC) was installed close to Cádiz (South Spain). Since then, additional stations have been installed in the Ibero-Moghrebian region. In 2005, the "WM" code was assigned by the FDSN and new partners were jointed: Evora University (UEVO, Portugal), the Scientifique Institute of Rabat (ISRABAT, Morocco), and GFZ. Now days, the WM network is composed by 15 BB stations, all of them with Streckaisen STS-2 or STS-2.5 sensors, Quanterra or Earthdata digitizers and SeiscomP. Most them have co-installed a permanent geodetic GPS stations, and some them also have an accelerometer. There are 10 stations deployed in Spanish territory (5 in the Iberian peninsula, 1 in Balearic islands and 4 in North Africa Spanish places) with VSAT or Internet communications, 2 in Portugal (one of them without real time), and 3 in Morocco (2 VSAT and 1 ADSL). Additionally, 2 more stations (one in South Spain and one in Morocco) will be installed along this year. Additionally ROA has deployed a permanent real time VBB (CMG-3T: 360s) station at the Alboran Island. Due to the fact that part of the seismic activity is located at marine areas, and also because of the poor geographic azimuthal coverage at some zones provided by the land stations (specially in the SW of the San Vicente Cape area), ROA and UCM have acquired six broad band "LOBSTERN" OBS, manufactured by KUM (Kiel, Germany), conforming the OBS FOMAR pool. Three of them with CMG-40T sensor and the other with Trillium 120. These OBS were deployed along the Gibraltar strait since January to November 2014 to study the microseismicity in the Gibraltar strait area. In September 2015 FOMAR network has been deployed in SW of the San Vicente Cape for 8 months as a part of

MeProRisk - a toolbox for evaluating risks in exploration, development, and operation of geothermal reservoirs

Clauser, C.

When developing geothermal resources, the risk of failure is still high when compared to hydrocarbon exploration. The MeProRisk projects aims at the improvement of strategies in all phases of the reservoir life cycle. It is a joint enterprise of five university institutes at RWTH Aachen University, Free University Berlin, and Kiel University. Two partners, namely Geophysica Beratunggesellschaft mbH, (Aachen), and RWE Dea AG (Hamburg) present the industrial side. It is funded by the German Ministry of Education and Science (BMBF). The key idea followed in this project is that the development of the understanding of a given reservoir is an iterative process. Starting from geological base knowledge and geophysical exploration one or more conceptual models will emerge, which will be incorporated in first numerical models. The use of inverse techniques in a broad sense will not only lead to an optimal model, but will produce uncertainty and resolution estimates for this model. This information may be used for further setup of optimal experiments, including the choice of exploration well locations. In later stages of reservoir development, the numerical models will be continuously updated based on the most recent models. Once wells have been drilled, the character of experiments shifts from static methods to dynamic interaction with the reservoir, e.g. by injection experiments and their monitoring. The use of all the methods with one simulation tool poses large challenges. Inverse problems require orders of magnitude larger computer resources, and the development of appropriate theoretical and numerical methods for this is on of the primary aims of this project. Due to the less obvious signatures of geothermally relevant targets, it is also necessary to improve the experimental base for model setup and update by developing new and better methods for some of the key problems in the case of geothermal targets. Among these are the development of methods to estimate

Pharmacological activation of cannabinoid receptors elicits antitumoral responses in different cancer models. However, the biological role of these receptors in tumor physio-pathology is still unknown. We analyzed CB2 cannabinoid receptor protein expression in two series of 166 and 483 breast tumor samples operated in the University Hospitals of Kiel, Tübingen, and Freiburg between 1997 and 2010 and CB2 mRNA expression in previously published DNA microarray datasets. The role of CB2 in oncogenesis was studied by generating a mouse line that expresses the human V-Erb-B2 Avian Erythroblastic Leukemia Viral Oncogene Homolog 2 (HER2) rat ortholog (neu) and lacks CB2 and by a variety of biochemical and cell biology approaches in human breast cancer cells in culture and in vivo, upon modulation of CB2 expression by si/shRNAs and overexpression plasmids. CB2-HER2 molecular interaction was studied by colocalization, coimmunoprecipitation, and proximity ligation assays. Statistical tests were two-sided. We show an association between elevated CB2 expression in HER2+ breast tumors and poor patient prognosis (decreased overall survival, hazard ratio [HR] = 0.29, 95% confidence interval [CI] = 0.09 to 0.71, P = .009) and higher probability to suffer local recurrence (HR = 0.09, 95% CI = 0.049 to 0.54, P = .003) and to develop distant metastases (HR = 0.33, 95% CI = 0.13 to 0.75, P = .009). We also demonstrate that genetic inactivation of CB2 impairs tumor generation and progression in MMTV-neu mice. Moreover, we show that HER2 upregulates CB2 expression by activating the transcription factor ELK1 via the ERK cascade and that an increased CB2 expression activates the HER2 pro-oncogenic signaling at the level of the tyrosine kinase c-SRC. Finally, we show HER2 and CB2 form heteromers in cancer cells. Our findings reveal an unprecedented role of CB2 as a pivotal regulator of HER2 pro-oncogenic signaling in breast cancer, and they suggest that CB2 may be a biomarker with

In the field of space life sciences, the demand of an interdisciplinary and specific training of young researchers is high due to the complex interaction of medical, biological, physical, technical and other questions. The Helmholtz Space Life Sciences Research School (SpaceLife) offers an excellent interdisciplinary training for doctoral students from different fields (biology, biochemistry, biotechnology, physics, psychology, nutrition or sports sciences and related fields) and any country. SpaceLife is coordinated by the Institute of Aerospace Medicine at the German Aerospace Center (DLR) in Cologne. The German Universities in Kiel, Bonn, Aachen, Regensburg, Magdeburg and Berlin, and the German Sports University (DSHS) in Cologne are members of SpaceLife. The Universities of Erlangen-Nürnberg, Frankfurt, Hohenheim, and the Beihang University in Beijing are associated partners. In each generation, up to 25 students can participate in the three-year program. Students learn to develop integrated concepts to solve health issues in human spaceflight and in related disease patterns on Earth, and to further explore the requirements for life in extreme environments, enabling a better understanding of the ecosystem Earth and the search for life on other planets in unmanned and manned missions. The doctoral candidates are coached by two specialist supervisors from DLR and the partner university, and a mentor. All students attend lectures in different subfields of space life sciences to attain an overview of the field: radiation and gravitational biology, astrobiology and space physiology, including psychological aspects of short and long term space missions. Seminars, advanced lectures, laboratory courses and stays at labs at the partner institutions or abroad are offered as elective course and will provide in-depth knowledge of the chosen subfield or allow to appropriate innovative methods. In Journal Clubs of the participating working groups, doctoral students learn

The Earth Science Women's Network (ESWN; ESWNonline.org) is an international peer-mentoring network of women in the Earth Sciences, many in the early stages of their careers. ESWN's mission is to promote career development, build community, provide opportunities for informal mentoring and support, and facilitate professional collaborations. This has been accomplished via email and a listserv, on Facebook, at in-person networking events, and at professional development workshops. In an effort to facilitate international connections among women in the Earth Sciences, ESWN has developed a password protected community webpage supported by AGU and a National Science Foundation ADVANCE grant where members can create an online presence and interact with each other. For example, groups help women to connect with co-workers or center around a vast array of topics ranging from research interests, funding opportunities, work-life balance, teaching, scientific methods, and searching for a job to specific challenges faced by women in the earth sciences. Members can search past discussions and share documents like examples of research statements, useful interview materials, or model recommendation letters. Over the last 10 years, ESWN has grown by word of mouth to include more than 1600 members working on all 7 continents. ESWN also offers professional development workshops at major geologic conferences around the world and at ESWN-hosted workshops mostly exclusively throughout the United States. In 2014, ESWN offers a two day international workshop on communication and networking skills and career development. Women working in all disciplines of Earth Sciences from later PhD level up to junior professors in Europe are invited to the workshop that will be held in Kiel, Germany. The workshop offers participants an individual personality assessment and aims at providing participants with improved communication and networking skills. The second focus will be to teach them how to

Analysis of the Rotational Spectrum of HDO in its v_2 = 0 and 1 Vibrational States up to 2.8 THz

The rotational and rovibrational spectra of H_2O and its isotopologs, including HDO, are of great importance for atmospheric chemistry, astrophysics, and basic sciences. We recorded rotational spectra of HDO in the ground and first excited bending state from the microwave region up to 2.8 THz. Several spectrometers were employed in Kiel, Köln, and Pasadena. An up-to-date combined analysis with rovibrational data was presented, footnote{S. Brünken, PhD thesis, Universität zu Köln, July 2005, Cuvillier Verlag, Göttingen} in which a Hamiltonian based on Euler functions was used to overcome convergence difficulties of the conventional Watson Hamiltonian. The model had been employed previously, e. g., in a related analysis of D_2O spectra with v_2 ≤ 1. Recently, many more data have been obtained in Köln as well as in Pasadena. Including multiple measurements, these add up to about 230 and 100 new transition frequencies in v_2 = 0 and 1, respectively, reaching J = 17/13 and K_a = 9/5. In addition, a critically evaluated compilation of IR data was published very recently. Difficulties in reproducing the data within experimental uncertainties prompted a reanalysis of the data starting at small quantum numbers and extending the data set in small portions. At lower quantum numbers, difficulties were due to, e. g., few typographical errors and misassignments. At higher quantum numbers, interactions between v_2 = 0 and 1 as well as between these and higher states (e. g. v_2 = 2/v_1 = 1, which interact through Fermi resonance) are more important. The limitation of the present analysis to the lowest two vibrational states affords some transitions to be excluded from the analysis and causes a truncation of the data set at some values of J and K_a.

Under the primary utilisation of phytosanitary production factors such as selection of variety, crop rotation and N fertilisation according to plant requirements, the IPM Wheat Model comprises the elements diagnosis (qualitative = type of pathogen, quantitative = disease severity), scientifically grounded treatment thresholds which, as critical values in pathogen development, can be applied to define the optimum time of fungicide application, and pathogen-specific effective fungicides and application amounts. This leads to the location and year-specific optimised control of the pathogen and of the associated yield performance. After several years of development in Bavaria (from 1985 on) and Schleswig-Holstein (1993-1999), the model was tested as part of a project involving the Universities of Bonn and Kiel and the plant protection services of the German states of Lower Saxony, North Rhine-Westphalia and Schleswig-Holstein in a three-year study (1999-2001) in interregional locations (usually nine per state) with the winter wheat variety Ritmo (interregional indicator variety) and a further variety of regional importance in different variations (untreated control, three to four times growth stage-oriented variants for the determination of the absolute damage potential, IPM-variant). In exact records (approx. 12 dates per vegetation period), the disease epidemics were recorded weekly. With the genetically uniform indicator variety Ritmo, the results documented substantially differing year- and location-specific disease and yield patterns. Interregionally, a broad wheat pathogen spectrum (Puccinia striiformis, P. recondita, Septoria tritici, Stagonospora (syn. Septoria) nodorum, Blumeria (syn. Erysiphe) graminis, Pseudocercosporella herpotrichoides, Drechslera tritici-repentis) in differing composition, disease severity and damage effect was demonstrated. The heterogeneity of the infection and damage patterns was increased in the case of the second variety, in

It has been demonstrated that the relative distribution of heterocyst glycolipids (HGs) in cultures of N2-fixing heterocystous cyanobacteria is largely controlled by growth temperature, suggesting a potential use of these components in paleoenvironmental studies. Here, we investigated the effect of environmental parameters (e.g., surface water temperatures, oxygen concentrations and pH) on the distribution of HGs in a natural system using water column filtrates collected from Lake Schreventeich (Kiel, Germany) from late July to the end of October 2013. HPLC-ESI/MS (high-performance liquid chromatography coupled to electrospray ionization-mass spectrometry) analysis revealed a dominance of 1-(O-hexose)-3,25-hexacosanediols (HG26 diols) and 1-(O-hexose)-3-keto-25-hexacosanol (HG26 keto-ol) in the solvent-extracted water column filtrates, which were accompanied by minor abundances of 1-(O-hexose)-3,27-octacosanediol (HG28 diol) and 1-(O-hexose)-3-keto-27-octacosanol (HG28 keto-ol) as well as 1-(O-hexose)-3,25,27-octacosanetriol (HG28 triol) and 1-(O-hexose)-3-keto-25,27-octacosanediol (HG28 keto-diol). Fractional abundances of alcoholic and ketonic HGs generally showed strong linear correlations with surface water temperatures and no or only weak linear correlations with both oxygen concentrations and pH. Changes in the distribution of the most abundant diol and keto-ol (e.g., HG26 diol and HG26 keto-ol) were quantitatively expressed as the HDI26 (heterocyst diol index of 26 carbon atoms) with values of this index ranging from 0.89 in mid-August to 0.66 in mid-October. An average HDI26 value of 0.79, which translates into a calculated surface water temperature of 15.8 ± 0.3 °C, was obtained from surface sediments collected from Lake Schreventeich. This temperature - and temperatures obtained from other HG indices (e.g., HDI28 and HTI28) - is similar to the one measured during maximum cyanobacterial productivity in early to mid-September and suggests that HGs

The Hawaii Undersea Research Laboratory (HURL) was established by NOAA at the University of Hawaii 25 years ago as part of its National Undersea Research Program. HURL's mission is to study deep water marine processes in the Pacific Ocean through a competitive proposal and review process. The dual Pisces IV and Pisces V 2000-meter manned submersibles, an RCV-150 1000-meter ROV, and multibeam equipped support ship R/V Ka'imikai-o-Kanaloa ( KoK) were largely acquired from the petroleum industry then adapted and upgraded to carry out cutting edge scientific expeditions. These studies range from active submarine volcanoes, delicate precious coral gardens, endangered marine mammal and fisheries management, to engineering surveys and deployment of observatory systems. HURL successfully completed a major 5-month expedition to the South Pacific during March-August 2005, working in the waters of New Zealand, Tonga, American Samoa, and the U.S. Line Islands covering a distance of nearly 14,500 nautical miles. This mission was significant in both the scientific merit and scope of operations, consisting of 8 different cruise legs at 21 study sites, with 12 chief and co-chief scientists, 58 total science team participants, and completing 61 out of 56 scheduled Pisces science dives, 17 ROV dives, 5 multibeam survey areas, 6 CTD rosette deployments, and 7 instrument mooring recoveries. The $3.5 million expedition was funded by an international partnership with New Zealand agencies (GNS & NIWA) and the University of Kiel in Germany along with the NOAA Office of Exploration and National Undersea Research Program. While most of the individual cruise legs focused on active submarine volcanoes of the Tonga-Kermadec Islands Arc and the Samoan hot spot chain with their hydrothermal systems and associated biological communities, others concentrated on marine protected areas including those of American Samoa and the remote atolls of the Line Islands of the Central Pacific.

Atmospheric and Oceanic Response to Southern Ocean Deep Convection Oscillations on Decadal to Centennial Time Scales in Climate Models

Many current coupled global climate models simulate open ocean deep convection in the Southern Ocean as a recurring event with time scales ranging from a few years to centennial (de Lavergne et al., 2014, Nat. Clim. Ch.). The only observation of such event, however, was the occurrence of the Weddell Polynya in the mid-1970s, an open water area of 350 000 km2 within the Antarctic sea ice in three consecutive winters. Both the wide range of modeled frequency of occurrence and the absence of deep convection in the Weddell Sea highlights the lack of understanding concerning the phenomenon. Nevertheless, simulations indicate that atmospheric and oceanic responses to the cessation of deep convection in the Southern Ocean include a strengthening of the low-level atmospheric circulation over the Southern Ocean (increasing SAM index) and a reduction in the export of Antarctic Bottom Water (AABW), potentially masking the regional effects of global warming (Latif et al., 2013, J. Clim.; Martin et al., 2014, Deep Sea Res. II). It is thus of great importance to enhance our understanding of Southern Ocean deep convection and clarify the associated time scales. In two multi-millennial simulations with the Kiel Climate Model (KCM, ECHAM5 T31 atmosphere & NEMO-LIM2 ~2˚ ocean) we showed that the deep convection is driven by strong oceanic warming at mid-depth periodically overriding the stabilizing effects of precipitation and ice melt (Martin et al., 2013, Clim. Dyn.). Sea ice thickness also affects location and duration of the deep convection. A new control simulation, in which, amongst others, the atmosphere grid resolution is changed to T42 (~2.8˚), yields a faster deep convection flip-flop with a period of 80-100 years and a weaker but still significant global climate response similar to CMIP5 simulations. While model physics seem to affect the time scale and intensity of the phenomenon, the driving mechanism is a rather robust feature. Finally, we compare the atmospheric and

Located in the Marmara Sea, the Istanbul-Silivri segment of the North Anatolian Fault (NAF) is known to be a seismic gap since 1766, although, in the last century, the NAF has caused major devastating earthquakes over most of its extent. This fault segment, void of seismicity, may be either creeping aseismically or blocked and accumulating enough strain to produce an earthquake of magnitude 7 or greater. This section of the NAF may thus represent a major seismic and tsunamigenic hazard for the Istanbul megalopolis, located only 40 km away. The objective of the MARSITE project, funded by the European Union and coordinated by the Observatory of the University of Kandilli (KOERI), is to determine the blocking state of the Istanbul-Silivri fault segment. In this context, an array of 10 acoustic transponders has been deployed on either sides of the fault, in the eastern part of the Kumburgaz Basin, to measure the displacements of the fault over a period of 3 to 5 years. The telemetric beacons (4 from the University of Brest and 6 from the GEOMAR Institute in Kiel) form two arrays fitted in one another. The principle of the experiment is to repeatedly measure the distance (ie two-way-travel time of acoustic pings) between pairs of beacons and thus to monitor the deformation of an array of 9 baselines, 500m to 3000m long, of which 5 cross obliquely the assumed fault trace. The French and German arrays are independent but ensure a redundancy of rangings along common baselines. Each acoustic transponder also monitors the temperature, pressure, sound-velocity and attitude (tiltmeters), every one or two hours. Data are stored in each beacon and can be downloaded from the surface using an acoustic modem. We present here the first 6 months of recording by the French array, from November 1st, 2014 to April 25, 2015. All acoustic transponders worked nominally for 6 months and appear to have remained stable on the seafloor. Recorded sea-bottom temperatures provide evidence for

Soil is a non-renewable resource with fundamental functions like filtering (e.g. water), storing (e.g. carbon), transforming (e.g. nutrients) and buffering (e.g. contamination). Degradation of soils is meanwhile not only to scientists a well known fact, also decision makers in politics have accepted this as a serious problem for several environmental aspects. National and international authorities have already worked out preservation and restoration strategies for soil degradation, though it is still work of active research how to put these strategies into real practice. But common to all strategies the description of soil state and dynamics is required as a base step. This includes collecting information from soils with methods ranging from direct soil sampling to remote applications. In an intermediate scale mobile geophysical methods are applied with the advantage of fast working progress but disadvantage of site specific calibration and interpretation issues. In the framework of the iSOIL project we present here some case studies for soil mapping performed using multiple geophysical methods. We will present examples of combined field measurements with EMI-, GPR-, magnetic and gammaspectrometric techniques carried out with the mobile multi-sensor-system of Kiel University (GER). Depending on soil type and actual environmental conditions, different methods show a different quality of information. With application of diverse methods we want to figure out, which methods or combination of methods will give the most reliable information concerning soil state and properties. To investigate the influence of varying material we performed mapping campaigns on field sites with sandy, loamy and loessy soils. Classification of measured or derived attributes show not only the lateral variability but also gives hints to a variation in the vertical distribution of soil material. For all soils of course soil water content can be a critical factor concerning a succesful

Several studies have established the relevance of the JNK pathway in inflammatory bowel diseases. The present study analyzed the therapeutic effect of D-JNKI-1, a specific JNK-inhibiting peptide, in a low-dose dextran sulfate sodium (DSS model of chronic colitis. Methods: DSS colitis was induced in female C57/BL6 mice by cyclic administration using different concentrations of DSS (1.0% and 1.5%. Mice in the intervention groups received subcutaneous administration of 1 µg/kg D-JNKI-1 on days 2, 12, and 22. They were monitored daily to assess the severity of colitis, body weight, stool consistency, and the occurrence of occult blood or gross rectal bleeding using evaluation of the disease activity index. The animals were sacrificed after 30 days, and the inflamed intestine was histologically evaluated using a crypt damage score. Immunohistochemical quantification of CD4+ and CD8+ cells was also carried out. Results: Administration of 1 µg/kg D-JNKI-1 resulted in a significant decrease in the disease activity index (P = 0.013 for 1.0% DSS; P = 0.007 for 1.5% DSS. As a mild form of colitis was induced, histological examination did not show any distinct damage to the mucosa and crypts. However, expression of CD4+ and CD8+ cells was reduced in mice treated with D-JNKI-1 (not

40Ar-39Ar age clustering in the active phonolitic Cadamosto Seamount (Cape Verdes): Indications for periodic magmatic activity

The Cape Verde archipelago is situated 400-800 km off the west coast of Africa and is comprised of a northern and southern chain of islands and seamounts. Morphological observations and previous radiometric dating of the islands indicate a slow age progression, over 22 Ma, from east to west (Holm et al. 2008). We present the first radiometric ages for Cadamosto Seamount, which is composed of complex evolved volcanics and is situated at the southwestern tip of the Cape Verde archipelago (e.g. Barker et al. 2012). We analyzed five different submarine phonolites that were sampled by remotely operated vehicles (ROV) Kiel 6000 and dredging during the RV Meteor (M80/3) and RV Poseidon (POS320/2) cruises. Fresh sanidine, nepheline, and biotite grains were selected and carefully prepared for 40Ar-39Ar single grain total fusion analysis. Sanidine single grain 40Ar-39Ar ages from 5 samples range from 11.5 ± 6.5 ka to 349.0 ± 20.4 ka (2σ errors), and cluster in several age groupings (using the decay constant and atmospheric air ratio of Steiger & Jäger (1977), and age standard TCS2 (27.87 ± 0.04 Ma; 1σ; M.A. Lanphere, pers. comm.)). Three age groups can be identified within the youngest (0-170 ka) sanidines, which are separated by periods of 52-54 ka. Nepheline grains from one sample yielded much older ages of 169.5 ± 16.5 ka to 1521.5 ± 8.3 ka (2σ). Our data suggests young ages for the Cadamosto Seamount, which is in accordance with recorded seismic activity (Grevemeyer et al. 2010), and its position adjacent to the recently active islands of Fogo (last eruption in 2014/2015) and Brava (recent seismic activity). The different sub-groups of sanidine 40Ar-39Ar ages can be used to identify different activity maxima corresponding to cycles of magmatic productivity in a long-lived magmatic system. Ongoing petrologic investigations will be used to identify the relative importance of processes such as mantle melting rates, magma replenishment and magma chamber processes

Halogens are excellent tracers of hydrothermal fluid sources and in-situ LA-ICP-MS analysis of Cl and Br in single fluid inclusions has provided fundamentally new insight into hydrothermal fluid flow and ore formation. There is mounting evidence that enrichment and depletion of Br relative to Cl may be caused by a number of processes beyond seawater evaporation and halite dissolution which cannot be discriminated on the basis of Br/Cl ratios alone. Expanding the analytical capabilities of fluid inclusion LA-ICP-MS analysis to include iodine would allow to discern between selective and coupled enrichment processes of Cl, Br and I, even in geologically complex samples that are inaccessible to bulk extraction techniques. We present iodine concentration data determined by LA-ICP-MS analysis of synthetic fluid inclusions, using the Sca17 scapolite reference material for external standardization (Seo et al., 2011). Iodine concentrations in Sca17 were determined using the Durango apatite standard. Four starting solutions containing I (0.3, 1.5, 27, 78 µg/g), Br (941, 1403, 2868, 4275 µg/g), Na (30.7, 94.7 mg/g), and Cl (50, 137 mg/g) (analyzed by ICP-OES and ICP-MS at CAU Kiel) were prepared by dissolving reagent grade chemical powders in ultra-pure water. Spherical inclusions (up to 40 µm) were synthesized from the starting solutions in pre-cracked, HF-treated synthetic quartz crystals which were placed in gold capsules and equilibrated at 600°C, 100/200 MPa in cold seal pressure vessels. Fluid inclusion LA-ICP-MS analysis (University of Helsinki) yielded average I concentrations in excellent agreement with the starting solutions (27.3 µg/g ± 14 %RSD for the 27 µg/g solution and 77.6 µg/g ± 8.3 %RSD for the 78 µg/g solution). Average Br and I concentrations deviate less than 10 % from solution concentration values. For the low I concentration solutions, the synthetic inclusions were too small to detect I. Thus, given suitable standard materials and sufficient

This concurs with the results of the Kiel Climate Model, which show an increase in OMZ volume during the last 9 kyr related to the increasing age of the OMZ water mass.

Assessing Methane Fluxes in a Small Run-of-River Reservoir: The Importance of Adjacent Marshland

We investigate methane (CH4) emissions from a small run-of-river impoundment, the Schwentine River in Kiel, Germany. Small dammed rivers, while important regions for carbon transformation, are presently not considered in the terrestrial carbon budget and are under-represented in CH4 emission studies. Using state-of-the-art monitoring techniques, we determine that 1) the CH4 emissions well-exceed those reported for temperate reservoirs and 2) the hydrodynamic linkage to bordering marshland (consisting of reed belts, sidebays and creeks) is an important CH4 source for Schwentine River CH4. During our study, the Schwentine River discharged into the Kieler Fjord at 3 - 12 m3/s. CH4 measurements included 1) a moored sensor near the dam discharge, 2) discrete water sampling, and 3) real time surface flux measurements with floating chambers. We observed that the CH4 concentration increased nearly linearly from 2.5 km upstream towards the dam. The CH4 concentration near the dam discharge was logged and reported every 30 minutes nearly continuously from 11 July - 28 Sept 2011, and varied from 500 μmol/L to 2,200 μmol/L. Surprisingly, the CH4 mass discharge from the dam - ranging from 4 to 20 kg/day - increased with both temperature and flowrate, suggesting a flow-dependent CH4 source. We found that the bordering and numerous inundated reed belts, sidebays and small creeks, had significantly elevated CH4 concentrations. These marshland regions are relatively productive and quiescent compared to the main river, and trap organic and particulate matter, leading to enhanced CH4 production. As the river flowrate increases, the lateral exchange with these adjacent areas also increases. Using the CH4 concentration time series, measured surface diffusive and ebullition fluxes, and sediment CH4 porewater profiles, we estimate the relative contributions of CH4 in the main branch due to 1) sediment diffusion, 2) dissolution from sediment CH4 bubble release, and 3) lateral fluxes from

Implications of elevated CO2 on pelagic carbon fluxes in an Arctic mesocosm study – an elemental mass balance approach

Directory of Open Access Journals (Sweden)

J. Czerny

2013-05-01

Full Text Available Recent studies on the impacts of ocean acidification on pelagic communities have identified changes in carbon to nutrient dynamics with related shifts in elemental stoichiometry. In principle, mesocosm experiments provide the opportunity of determining temporal dynamics of all relevant carbon and nutrient pools and, thus, calculating elemental budgets. In practice, attempts to budget mesocosm enclosures are often hampered by uncertainties in some of the measured pools and fluxes, in particular due to uncertainties in constraining air–sea gas exchange, particle sinking, and wall growth. In an Arctic mesocosm study on ocean acidification applying KOSMOS (Kiel Off-Shore Mesocosms for future Ocean Simulation, all relevant element pools and fluxes of carbon, nitrogen and phosphorus were measured, using an improved experimental design intended to narrow down the mentioned uncertainties. Water-column concentrations of particulate and dissolved organic and inorganic matter were determined daily. New approaches for quantitative estimates of material sinking to the bottom of the mesocosms and gas exchange in 48 h temporal resolution as well as estimates of wall growth were developed to close the gaps in element budgets. However, losses elements from the budgets into a sum of insufficiently determined pools were detected, and are principally unavoidable in mesocosm investigation. The comparison of variability patterns of all single measured datasets revealed analytic precision to be the main issue in determination of budgets. Uncertainties in dissolved organic carbon (DOC, nitrogen (DON and particulate organic phosphorus (POP were much higher than the summed error in determination of the same elements in all other pools. With estimates provided for all other major elemental pools, mass balance calculations could be used to infer the temporal development of DOC, DON and POP pools. Future elevated pCO2 was found to enhance net autotrophic community carbon

This concurs with the results of the Kiel Climate Model, which show an increase in OMZ volume during the last 9 kyr related to the increasing age of the OMZ water mass.

Transrectal ultrasound(TRUS) guided HDR implantation of the prostate has been established at the Kiel University by Bertermann and Brix in 1986 and there are to date 179 (T1b-T3 No Mo) patients treated in a combined modality. The dose for the implant was 2x 15 Gy on the capsule of the prostate in 14-20 days. For local and regional lymph nodes 20 Gy external beam therapy (AP-PA pelvic portals), 20 Gy with an individual transmission block (100% for subclinical disease, 70% and 50% according to the implant dosimetry for the prostate) and 10 Gy small volume irradiation for the prostate was applied, conventional fractioned. Total dose after the therapy 70 Gy for the prostate and 50 Gy for the subclinical disease in 6-7 weeks. As a quality control method we use since 1991 in vivo dosimetry on the medial rectum wall as well as in the prostatic part of the urethra. Regular follow-up 3-118 months after therapy (median 55) with PSA, digital rectal examination, control TRUS with volumetry (after one year with biopsy) and bone scan. There were no major early side effects within the first three months. Proctitis till 1991 with a duration up to 12 months 49%, prolonging more than one year in 23 %, (total proctitis 72.6%). Dysuria in up to 12 months 30 %, long lasting 30% (total number of dysuria 60 %). Erectile dysfunction in 56 %. Because of the number of the side effects 1991 we changed the external beam technique: instead of the biaxial arch therapy the AP-PA portals, and reduced irradiated volume (from 6480 cm 3 to 5040 cm 3 ). We introduced instead of the small volume arch therapy for 10 Gy external boost the box-technique with shielding the back part of the rectum and the upper part of the bladder resulting additional volume reduction. Through the 15 Gy HDR brachytherapy dose on the prostate capsule there are up to 8 Gy on the medial rectal wall, measured by in vivo dosimetry. This dose could not be responsible for the high number of side effects (see gynecological

Accumulation of deformation at convergent plate margins is recently identified to be highly discontinuous and transient in nature: silent slip events, non-volcanic tremors, afterslip, fault coupling and complex response patterns of the upper plate during a single event as well as across several seismic cycles have all been observed in various settings and combinations. Segments of convergent plate margins with high recurrence rates and at different stages of the rupture cycle like the Chilean margin offer an exceptional opportunity to study these features and their interaction resolving behaviour during the seismic cycle and over repeated cycles. A past (TIPTEQ) and several active international initiatives (Integrated Plate Boundary Observatory Chile; IPOC-network.org) address these goals with research groups from IPG Paris, Seismological Survey of Chile, Free University Berlin, Potsdam University, Hamburg University, IFM-GEOMAR Kiel, GFZ Potsdam, and Caltech (USA) employing an integrated plate boundary observatory and associated projects. Results from these studies allow us to define the preseismic state - with respect to the Maule eartghquake - of the margin system at the south Central Chilean convergent margin. Here, two major seismic events have occurred in adjoining segments (Valdivia 1960, Mw = 9.5; Maule 2010, Mw = 8.8) yielding observations from critical time windows of the seismic cycle in the same region. Seismic imaging and seismological data have allowed us to relocate major rupture hypocentres and to locate the geometry and properties of the seismogenic zone. The reflection seismic data exhibit well defined changes of reflectivity and Vp/Vs ratio along the plate interface that can be correlated with different parts of the coupling zone and its hanging wall as well as with changes during the seismic cycle. Observations suggest an important role of the hydraulic system, and of lateral variation of locking degree on subsequent rupture and aftershock

The most common location is the lower back. Pharmacological treatment of this condition is challenging because of the range of causative mechanisms and the difficulty of balancing analgesic efficacy and tolerability. An international panel of clinical pain specialists met in September, 2009, to discuss the treatment of chronic low back pain, and to review preclinical and clinical data relating to the new analgesic, tapentadol. A lack of consensus exists on the best treatment for low back pain. The range of regularly prescribed pharmacological agents extends from nonopioids (paracetamol, NSAIDs, and COX-2 inhibitors to opioids, antidepressants and anticonvulsants. Pain relief may be compromised, however, by an undetected neuropathic component or intolerable side effects. Treatment is potentially life-long and effective analgesics are urgently needed, with demonstrable long-term safety. Combining separate agents with different mechanisms of action could overcome the limitations of present

In this study, the mechanics of forearc basins will be the object of a numerical investigation to understand the relationships between the wedge deformation and forearc basin formation. The aim of this work is to gain insight into the dynamics of the formation of the forearc basin on top of a deforming accretionary wedge, including the mechanism of formation of accommodation space and preservation of basin stratigraphy. Our tool is a two-dimensional numerical model that includes the rheological properties of the rock, including effective internal friction angle, effective basal friction angle, thermally-activated viscosity and strain softening. We also simulate different sedimentation rates in the basin, to study the influence of underfilled and overfilled basin conditions on wedge deformation. The stratigraphy in the basin is simulated, because, as noted in earlier studies, underfilled conditions incourage tectonic deformation in the inner wedge. We compare the numerical model to basins along the Sunda-Java Trench and the Alaskan margin. The Sunda-Java Trench shows a variety of structural and basin styles including underfilled and overfilled basins and different wedge geometries along the same trench. We interprete and document these structural styles, using depth migrated seismic sections of the Sunda Trench, obtained in three surveys, GINCO (11/98 - 01/99), MERAMEX (16/09/04 - 7/10/04) and SINDBAD (9/10/06 - 9/11/06) and made available by the IFM-GEOMAR group in Kiel and the Bundesanstalt für Geowissenschaften and Rohstoffe (BGR) in Hannover. On the Alaska margin we focus on the Kenai Peninsula, Kodiak Island plateau. This segment of the margin has one of the largest accretionary wedge - forearc basin systems in the world. It also exhibits a double forearc basin system with an interior basin (Cook inlet) and an outer basin, outboard of Kodiak Island, which is a prime candidate for a negative-alpha basin, as described by Fuller et al., (Geology, 2006).

D-24148 Kiel, Germany, (*correspondence: kheydolph@ifm-geomar.de) 2 Integrated Ocean Drilling Program, Texas A&M University, 1000 Discovery Drive, College Station, Texas 77845-9547 (geldmacher@iodp.tamu.edu) The submarine Shatsky Rise plateau, a unique large igneous province (LIP) in the northwest Pacific Ocean ca. 1500 km east of Japan, is the only large intraoceanic plateau, which formed during the Late Jurassic to Early Cretaceous at a time period with numerous reversals of the Earth's magnetic field. These magnetic reversals combined with bathymetric data allow a detailed reconstruction of the tectonic history. Accordingly the three main volcanic edifices Tamu, Ori and Shirshov massifs formed by massive volcanism during a short time span along a southwest - northeast trending, rapidly spreading triple junction. Therefore, the magnetic and bathymetric data suggest that the Shatsky Rise formed through the interaction of a mantle plume head with a ridge [1, 2]. We present new Sr, Nd and Pb (double spike) and for the first time Hf isotope data from volcanic rocks of relatively fresh basaltic lava flows from recent IODP Exp. 324 Site U1347 and ODP Leg 198 Site 1213 (Hf data) both located on Tamu massif the southernmost (oldest) volcanic edifice of Shtasky Rise. Initial 176Hf/177Hf and 143Nd/144Nd isotopic compositions are fairly uniform throughout the entire holes ranging between 0.283076 to 0.283100 and 0.512903 to 0.512981 respectively, showing neither distinct MORB nor intraplate (plume) affinity. Relatively unradiogenic 87Sr/86Sr data ranging from 0.70276 to 0.70296 mostly overlaps with Pacific MORB like values. In a Nd vs Hf isotope plot they form a tight cluster at the edge of the Pacific MORB field below the present-day Hf-Nd mantle array. Although initial Pb double spike 206Pb/204Pb and 208Pb/204Pb isotopic compositions for Site U1347 range from 18.13 to 18.46 and 37.71 to 37

For the line intensities we have used an extensive set of individual line intensities measured recently [J. Mol. Spectrosc., 218 (2003) 151]. All these experimental data were very satisfactorily reproduced using the theoretical model described above and an improved set of line positions and intensities was generated for the ν5 and 2 ν9 bands allowing one to better model the HNO 3 absorption in the 11 μm spectral domain.

there are major, rift-like, sedimentary basins underlying the area of the Azov Sea and the inverted north-eastern margin of the Black Sea. It can be speculated that one of these basins may represent the previously unknown western prolongation of the Jurassic-aged Greater Caucasus back-arc basin and that the other may be the legacy of earlier - Late Palaeozoic-Triassic - extensional tectonics in this area.

combines electromagnetic surface and in-situ geochemical measurements: The changes in formation resistivity / hydroelectric conductivity could be used as "first-level" parameter to identify potential intrusion locations. Subsequent targeted drilling and probe measurements of pH and TIC could be used to reject or confirm an intrusion event. Further sampling and analysis can be performed at this stage for the impact assessment if required. Next to considering regulative, environmental and public aspects, the approach helps to reduce financial strains by significantly lowering the number of required monitoring wells.

Non-Hodgkin's lymphoma - Part I: Etiology, pathology, diagnostic evaluation and principles of management

Objective: To review the approach to the diagnosis, classification, assessment, treatment and continuing management of patients with non-Hodgkin's lymphoma with an emphasis on the role of radiation therapy and the management of localized disease. Non-Hodgkin's lymphomas are a diverse group of diseases with an age standardized incidence of approximately 17 per 100,000 population. They become more common with increasing age and frequently involve extranodal sites. A number of potential etiological causes have been defined e.g. congenital and acquired immunodeficiency states, viruses, ionizing radiation, chronic inflammatory diseases and environmental toxins. Management is most influenced by the histological type of lymphoma. Numerous classifications have derived from architectural and cytological observations (Rappaport), concepts involving morphologic and phenotypic characterization of lineage and differentiation (Lukes-Collins, Kiel), and grade in the context of cytological differentiation and prognosis (Working Formulation). The introduction of the REAL classification has characterized clinico-pathological entities within a B-cell, T-cell and Hodgkin's disease framework, and recognized histopathologic grade as a variable within each category. The utility of this approach is likely to increase as disease entities become further defined through karyotypic and genotypic characterization. Stage is the other principal determinant of management. Whilst the Ann Arbor staging classification is employed routinely, its limitations in the context of extranodal disease, characterization of local disease extent and bulk have resulted in the incorporation of additional prognostic factors into management policies. Important prognostic factors include patient-related variables (age, performance status), disease-related attributes (bulk, number of involved nodes, B-symptoms) and biological attributes (LDH, ESR, β-2 macroglobulin, soluble CD-30, proliferation indices).

Geoportals are important elements of spatial data infrastructures (SDIs) that are strongly based on GIS-related web services. These services are basically meant for distributing, documenting and visualizing (spatial) data in a standardized manner; an important but challenging task especially in large scientific projects with a high number of data suppliers and producers from various countries. This presentation focuses on introducing the free and open-source based geoportal solution developed within the research project CLIMB (Climate Induced Changes on the Hydrology of Mediterranean Basins, www.climb-fp7.eu) that serves as the central platform for interchanging project-related spatial data and information. In this collaboration, financed by the EU-FP7-framework and coordinated at the LMU Munich, 21 partner institutions from nine European and non-European countries were involved. The CLIMB Geoportal (lgi-climbsrv.geographie.uni-kiel.de) stores and provides spatially distributed data about the current state and future changes of the hydrological conditions within the seven CLIMB test sites around the Mediterranean. Hydrological modelling outcome - validated by the CLIMB partners - is offered to the public in forms of Web Map Services (WMS), whereas downloading the underlying data itself through Web Coverage Services (WCS) is possible for registered users only. A selection of common indicators such as discharge, drought index as well as uncertainty measures including their changes over time were used in different spatial resolution. Besides map information, the portal enables the graphical display of time series of selected variables calculated by the individual models applied within the CLIMB-project. The implementation of the CLIMB Geoportal is finally based on version 2.0c5 of the open source geospatial content management system GeoNode. It includes a GeoServer instance for providing the OGC-compliant web services and comes with a metadata catalog (pycsw) as well

We focus on the south Central Chilean convergent margin and the North Chilean margin as natural laboratories embracing the recent Maule 2010 megathrust event. Here, major recent seismic events have occurred (south Central Chile: 1960, Mw = 9.5; 2010, Mw = 8.8; North Chile: 1995, Mw = 8; 2001, Mw = 8.7; 2007, Mw: 7.8) or are expected in the very near future (Iquique, last ruptured 1877, Mw = 8.8) allowing observation at critical time windows of the seismic cycle. Seismic imaging and seismological data have allowed us to relocate major rupture hypocentres and to locate the geometry of the locked zone and the degree of locking in both areas.

The Marine Network for Integrated Data Access (MaNIDA) builds a sustainable e-Infrastructure to support discovery and re-use of data from distinct marine and earth science data providers in Germany (see ESSI1.2 and ESSI2.2). Thereby we implement the "Data Portal of German Marine Research" for coherent discovery, view, download and dissemination of aggregated content. MaNIDA receives a unique momentum from the cooperation and financial partnership between main German marine research institutes (AWI, MARUM, HZG, GEOMAR, Uni Hamburg, Uni Kiel, Uni Bremen) and the Federal Maritime and Hydrographic Agency as well as active participation in international and major EU-initiatives (ICSU, GEOSS, SeaDataNet, EMODNET, ODIP). Together with a coherent management strategy coordinated by the Alfred Wegener Institute, Helmholtz Center for Polar and Marine Research, sustainability will be achieved via the long-term commitment of framework funding by the Helmholtz Association, Germany's largest scientific research organization for large-scale facilities and scientific infrastructure. Strategic Aims The installation of the "Data Portal of German Marine Research" will address the urgent demands of the German research community for reliable and easy access to marine research data at one single point of access and truth. Primary focus will be given to data derived from nationally operated research and monitoring facilities (vessels, observatories, alert systems, etc), whereby related contextual content and publications will become an integral part of the aggregation effort. For the scientific community we define responsibilities and commitments across partners while complementing existing data repositories and the new portal with well-articulated workflows from the instrument to the data product. Necessary level of quality assurance and user support will be implemented to achieve substantial enhancements in the whole lifecycle management of marine scientific data. The creation of a data

a variation of j{sub c} and I{sub c}R{sub n} by the s-layer thickness up to the value of nonmagnetic SIS junctions is notable. Additionally information on the emergence of superconductivity with the s-layer thickness was acquired. The introduction of this thesis (Chapter 1) is intended to motivate the experimental efforts and put them into the research context. An account on the evolving field of quantum information processing shall highlight the relevance of performance enhancements of superconducting devices. The chapter also introduces the theories of electron tunneling and effects at Josephson barriers, which are essential to analyse the experimental data. Moreover a description of magnetism along with mechanisms and experiments related to π Josephson junctions are presented. In the following (Chapter 2) an overview about machines and processes for the fabrication and characterisation of thin film devices is given. The preparation of samples was performed at facilities of the Technical Faculty of the University of Kiel. Also information about the experimental setup are given. A focus is put on the deposition of layers with thickness gradients across the wafer and combinatorial sputtering to achieve independent variations of two layer parameters. Finally (Chapter 3) experimental data for different types of Josephson junctions are shown. Related theories, relevant publications and a discussion are introduced along with the data.

Changes in 53Cr/52Cr (δ53Cr) values recorded by biogenic carbonates are emerging as a proxy for variations in the redox state of the Earth's oceans and atmosphere (e.g. [1], [2]). We investigate the ability of modern carbonate shells (Mytilus edulis) to record the δ53Cr composition of ambient seawater in order to assess their utility as a paleo-redox proxy. Samples of cultivated M. edulis from the Kiel Fjord, Germany, were analyzed for their δ53Cr composition and Cr concentrations [Cr] using TIMS. To disentangle the pathway of Cr into the carbonate shell, a series of step-digestions of their organic outer sheaths (periostraca) and their intra-layer composition were performed. Bulk analyses of specimens with intact periostraca returned 16 to 34 ppb Cr with δ53Cr values ranging from 0.28 to 0.65 ± 0.1 (2SE) and thus fall within the range of surface seawater from the Baltic Sea (0.3 - 0.6 \\permil [3]). Partial removal of periostraca resulted in lower [Cr] (5 to 17 ppb) and δ53Cr values (-0.05 ± 0.15 \\permil). These results show a positive correlation between the amount of organic matter present in a sample and both [Cr] and δ53Cr (n = 9). With nearly complete removal of periostraca, the remaining [Cr] is significantly lower (less than 5 ppb) and can only be accessed by incineration of the carbonate shell. The correlation between [Cr], δ53Cr and the amount of periostracum present in bulk samples indicates that a significant proportion of preserved Cr may be associated with the organic outer sheath. The Cr endmember accessed after incineration is less likely associated with the carbonate crystal lattice. Instead, the δ53Cr values obtained after incineration are similar to those reported from terrestrial rocks, suggesting the influence of detrital particles. Alternatively, Cr may be reduced and subsequently re-oxidized during the mineralization of biogenic carbonates [4]. Seasonal changes in primary productivity in seawater may further influence the shell

j c and I c R n by the s-layer thickness up to the value of nonmagnetic SIS junctions is notable. Additionally information on the emergence of superconductivity with the s-layer thickness was acquired. The introduction of this thesis (Chapter 1) is intended to motivate the experimental efforts and put them into the research context. An account on the evolving field of quantum information processing shall highlight the relevance of performance enhancements of superconducting devices. The chapter also introduces the theories of electron tunneling and effects at Josephson barriers, which are essential to analyse the experimental data. Moreover a description of magnetism along with mechanisms and experiments related to π Josephson junctions are presented. In the following (Chapter 2) an overview about machines and processes for the fabrication and characterisation of thin film devices is given. The preparation of samples was performed at facilities of the Technical Faculty of the University of Kiel. Also information about the experimental setup are given. A focus is put on the deposition of layers with thickness gradients across the wafer and combinatorial sputtering to achieve independent variations of two layer parameters. Finally (Chapter 3) experimental data for different types of Josephson junctions are shown. Related theories, relevant publications and a discussion are introduced along with the data.

Ocean Cooperation. The EU Horizon 2020 AtlantOS project pools the efforts of 57 European and 5 non-European partners (research institutes, universities, marine service providers, multi-institutional organisations, and the private sector) from 18 countries to collaborate on optimizing and enhancing Atlantic Ocean observing. The project has a budget of € 21M for 4 years (April 2015 - June 2019) and is coordinated by GEOMAR Helmholtz Centre for Ocean Research Kiel, Germany (Prof. Dr. Martin Visbeck). The project is organized along work packages on: i) observing system requirements and design studies, ii) enhancement of ship-based and autonomous observing networks, iii) interfaces with coastal ocean observing systems, iv) integration of regional observing systems, v) cross-cutting issues and emerging networks, vi) data flow and data integration, vii) societal benefits from observing /information systems, viii) system evaluation and resource sustainability. Engagement with wider stakeholders including end-users of Atlantic Ocean observation products and services will also be key throughout the project. The AtlantOS initiative contributes to achieving the aims of the Galway Statement on Atlantic Ocean Cooperation that was signed in 2013 by the EU, Canada and the US, launching a Transatlantic Ocean Research Alliance to enhance collaboration to better understand the Atlantic Ocean and sustainably manage and use its resources.

rupture models. 1d-layered medium models are implemented for both near- and far-field data predictions. A highlight of our approach is a weak dependence on earthquake bulletin information: hypocenter locations and source origin times are relatively free source model parameters. We present this harmonized source modelling environment based on example earthquake studies, e.g. the 2010 Haiti earthquake, the 2009 L'Aquila earthquake and others. We discuss the benefit of combined-data non-linear modelling on the resolution of first-order rupture parameters, e.g. location, size, orientation, mechanism, moment/slip and rupture propagation. The presented studies apply our newly developed software tools which build up on the open-source seismological software toolbox pyrocko (www.pyrocko.org) in the form of modules. We aim to facilitate a better exploitation of open global data sets for a wide community studying tectonics, but the tools are applicable also for a large range of regional to local earthquake studies. Our developments therefore ensure a large flexibility in the parametrization of medium models (e.g. 1d to 3d medium models), source models (e.g. explosion sources, full moment tensor sources, heterogeneous slip models, etc) and of the predicted data (e.g. (high-rate) GPS, strong motion, tilt). This work is conducted within the project "Bridging Geodesy and Seismology" (www.bridges.uni-kiel.de) funded by the German Research Foundation DFG through an Emmy-Noether grant.

thank them. The white dwarf community has been steadily growing since the first white dwarf workshop, held in Kiel (Germany) in 1974. Some of the participants in the first colloquium have already effectively retired; others - although officially retired - continue to attend successive workshops, Professor Weidemann, one of the first organizers, being a leading example. We hope we will be able to continue counting on them for many years. A very graphical view of the evolution of the field can be found in the homepage of Professor Detlev Koester, who has collected pictures of almost all the previous workshops:. Additionally, several astronomers coming from related fields have joined our (not so) small community. Most importantly, several generations of young scientists gave their first talks in these workshops. In summary our community is an active one, and we have close, durable and solid ties of friendship. We are optimistic and we foresee that the spirit of the previous workshops will continue in future editions. We would like to express our deepest gratitude to our sponsors: The Universitat Politècnica de Catalunya (UPC), the Institut de Ciències de l'Espai (CSIC), the Institute for Space Studies of Catalonia (IEEC), the Spanish Ministry of Education and Science, the Generalitat de Catalunya, the Ajuntament de Barcelona, the School of Civil Engineering of Barcelona and UPCnet. Finally, the IEEC staff and our graduate students have enthusiastically supported the organization of the workshop in every single detail; without them we would have not succeeded. We thank them especially. Also, we acknowledge the task of the Scientific Organizing Committee, which gave their full support in all the scientific tasks.

In the frame of the European Union « THALES WAS RIGHT » and French ANR CATTELL SUBSISMANTI funding, an unprecedented array of 80 OBS, Ocean Bottom Seismometers of Géoazur Nice, INSU/IPGP Paris, IfM-GEOMAR Kiel, AWI Bremerhaven could gathered. They have been deployed for continuous recording over four months on the fore-arc domain of the Lesser Antilles subduction zone offshore Martinique, Dominica, Guadeloupe and Antigua Islands, by scientific cruises of N/O ATALANTE, F/S M. A. MERIAN and N/O ANTEA. One of the aims of this OBS array was the feasibility study of detecting at sea-bottom the seismological part of recently discovered phenomena such as NVT non-volcanic tremors and LP, for Long-Period events. The ability of detecting such transient signals is of importance, since they are possibly related to potential mega-thrust earthquakes and their preparation zone. At the Lesser Antilles subduction zone, the fore-arc domain overlying the seismogenic part of the interplate is located offshore, covered by as much as 4000 m of water. In this case, transient signals can be accessible only from OBS observations. Hence, there is a major difference, in the sense of the instrumental and logistical effort, with the subductions under NW US-Canada and under Central Japan where these signals have been discovered. There, the subduction zones have an emerged fore-arc that has allowed the chance discovery of those phenomena by regular instrument maintained routinely on land. Over 20 of the instruments were BB-OBS, with broadband seismic sensors, possibly the largest such gathering at the time of the experiment among the OBS types. Among those broadband OBS designed or used by different Institutions, there were at least three different seismometer brands and acoustical sensors, as well as different mechanical mounting and technical solutions for coupling them to ground. This did not facilitate data recovery and processing, but on the other hand, as planned by interweaving the

How the sedimentary Re/Mo ratio and Tl enrichments trace past and present opaline productivity

preconcentration step for Mo on particles to explain the very low Re/Mo ratios, while Re only seems to accumulate via diffusion. However, our data suggest that the carrier phases are not Mn-oxides but fresh biogenic detritus. Further, since Mo and Cd are well correlated (Böning et al., 2004) our findings suggest a similar, biodetrital source for both elements. This would imply a non-conservative behaviour of Mo, which corroborates findings where dissolved Mo becomes depleted in coastal and open-ocean waters and consequently enriched on biogenic particles after algal blooms (Tuit and Ravizza, 2003; Dellwig et al. 2007). Concerning Tl, it is yet to be determined wether this element is directly associated with the opaline hard parts or the related fresh organic matter. However, the implied particle reactivity of Tl suggests a non-conservative behaviour of this element. Further, our data do not support an involvement of Tl with Mn but rather an association with biological cycling. References: Böning, P. et al. (2009) Mar. Geol. 259, 112-121; Böning, P. et al.

Purpose: High-dose radiotherapy, delivered in an accelerated hypofractionated course, was utilized to treat prostate cancer. Therapy consisted of external beam radiotherapy (EBRT) and transrectal ultrasound (TRUS)-guided conformally modulated high-dose rate (HDR) brachytherapy. The purpose of this report is (1) to assess long-term comparative outcomes from three trials using similar accelerated hypofractionated regimes; and (2) to examine the long-term survival impact of a short course of ≤6 months adjuvant/concurrent androgen deprivation when a very high radiation dose was delivered. Methods and Materials: Between 1986 and 2000, 1,260 patients were treated at three institutions with pelvic EBRT (36-50 Gy) integrated with HDR prostate brachytherapy. The total dose including brachytherapy was given over 5 weeks. The biologic equivalent EBRT dose ranged between 90 and 123 Gy (median, 102 Gy) using an α /β of 1.2. Patient eligibility criteria included a pretreatment prostate-specific antigen ≥10, Gleason score ≥7, or clinical stage ≥T2b. A total of 1,260 patients were treated, and 934 meet the criteria. Kiel University Hospital treated 198 patients; William Beaumont Hospital, 315; and California Endocurietherapy Cancer Center, 459 patients. Brachytherapy dose regimes were somewhat different between centers and the dose was escalated from 5.5 x 3 to 15 Gy x 2 Gy. Patients were divided for analysis between the 406 who received up to 6 months of androgen deprivation therapy and the 528 patients who did not. All patients had a minimum follow-up of 18 months (3 times the exposure to androgen deprivation therapy). The American Society for Therapeutic Radiology and Oncology biochemical failure definition was used. Results: Mean age was 69 years. Median follow-up time was 4.4 years (range, 1.5-14.5); 4 years for androgen deprivation therapy patients and 4.9 for radiation alone. There was no difference at 5 and 8 years in overall survival, cause-specific survival, or

Pisa and the librarian Pozzetti at Bologna, and Karin Reich describes and edits Bessel's book critique of Gauss' Theoria Motus. How many one-time astronomers have to earn their living in other ways, become distracted from astronomical research, and vanish from the horizon of astronomical history? In the ninth paper, Hans-Joachim Ilgauds has traced the life of Georg Koch (1851-1905), who started his career as an astronomer at Leipzig Observatory in 1874. Later Koch worked at Hamburg Observatory, and then became an employee at the statistical office in Kiel, and finally director of the statistical office of the Hamburg revenue service. He was a collaborator for the statistical yearbook of German cities, and also contributed to a book investigating the causes and the impact of the cholera epidemic of 1892 in Hamburg. The last two papers deal with the circumstances of the discovery of the first Near-Earth asteroid (433) Eros. It was recorded on photographic plates taken at the Urania-Sternwarte Berlin and at Nice Observatory. The Berlin observer Witt announced the discovery, and only later, the Nice observer Charlois published a position of Eros. While all plates have disappeared, the authors Hans Scholl and Lutz D. Schmadel could prove that the Nice plate was poorly guided and Charlois would have been unable to discover the object. From a copy of the Berlin plate, published 50 years after the discovery by Witt's co-observer F. Linke, the exact position was determined, and the time of observation (which had not been published) was derived. The second article, by Lutz D. Schmadel, deals with the life of the Eros co-discoverer Felix Linke (1879-1959), who later worked in statistic offices, was a frequent writer of popular scientific articles, and later the editor of a journal, "Technik im Hotel'', and author of a book of the same title. As can be seen from the summaries given above, this collection of essays deals mainly with historical events that occurred in Germany and

comet hunters," said Shanklin, who is director of the British Astronomical Association's comet section. "It allows amateurs to discover some of the smallest comets ever seen. Yet they link us to sightings of great comets going back more than 2000 years." Nine of the comets found with LASCO, including SOHO-100, 101 and 102, passed the Sun at a safe distance. SOHO-49, which showed up in LASCO images in May 1998 and was designated as Comet 1998 J1, became visible to the naked eye in the southern hemisphere. But the great majority of SOHO's comets failed to survive very close encounters with the Sun. Snowballs in hell Of the first 100 SOHO comets, 92 vaporized in the solar atmosphere. Isaac Newton suggested 300 years ago that infalling comets might supply the Sun with fuel, but no one has ever tracked a comet that definitely hit the bright surface. Near misses are well known, and 100 years ago Heinrich Kreutz in Kiel, Germany, realized that several comets seen buzzing the Sun seemed to have a common origin, because they came from the same direction among the stars. These comets are now called the Kreutz sungrazers, and the 92 vanishing SOHO comets belong to that class. They were not unexpected. Between 1979 and 1989 the P78-1 and SMM solar satellites spotted 16 comets closing with the Sun. Life is perilous for a sungrazer. The mixture of ice and dust that makes up a comet's nucleus is heated like the proverbial snowball in hell, and can survive its visit to the Sun only if it is quite large. What's more, the very strong tidal effect of the Sun's gravity can tear the loosely glued nucleus apart. The disruption that created the many SOHO sungrazers was similar to the fate of Comet Shoemaker-Levy 9, which went too close to Jupiter and broke up into many pieces that eventually fell into the massive planet in 1994. "SOHO is seeing fragments from the gradual break-up of a great comet, perhaps the one that the Greek astronomer Ephorus saw in 372 BC," commented Brian Marsden of the

Obituary: Hans Albrecht Bethe, 1906-2005

Wijers, Ralph

2007-12-01

One of the unquestioned giants of physics and astrophysics, Hans Bethe, died on 6 March 2005, at the venerable age of 98, in his home town of Ithaca, New York. Seven decades of contributing to research and a Nobel Prize for his work on stellar hydrogen burning make a listing of his honors superfluous (besides being impossible in this space). Bethe was born in Strassburg, in then German Alsass Lothringen, on 2 July 1906. His father, Albrecht Julius Bethe (1872-1954), taught physiology at the University, and his mother, Anna Kuhn (1876-1966), was a musician and writer. Both his grandfathers were physicians. He spent his youth in Strassburg, Kiel, and Frankfurt, and some time in sanatoria due to tuberculosis. Hans's first scientific paper, at age 18, was with his father and a colleague, on dialysis. His education and early career in Germany brought him into contact with many top stars in the quantum revolution. Starting in Frankfurt in chemistry, Bethe soon switched to physics, taught there by Walter Gerlach and Karl Meissner, among others. In 1926, he successfully applied to join Arnold Sommerfeld's group in Munich, where he met one of his later long-term collaborators, Rudolf Peierls. Bethe considered his entry into physics to have come at an ideal time, with the new ideas of wave mechanics being developed and discussed right there; it was certainly also at an ideal place. His doctoral thesis was on the theory of electron diffraction by crystals, following the experimental work by Clinton Davisson and Lester Germer and the work on X-ray diffraction by Max von Laue and Paul Ewald. The newly minted doctor went from there briefly to Frankfurt and then to Ewald in Stuttgart, where he felt at home academically and personally. In 1939, Bethe would marry Ewald's daughter Rose. Not much later, though, Sommerfeld recalled him to Munich, where Sommerfeld created a Privatdozent position for him. There he worked out the solution for a linear chain of coupled spins by what we
