  1. Agnieszka, Antigone: The Antigone Myth in Andrzej Wajda’s Katyn and in Dominik Smole’s Antigona

    Directory of Open Access Journals (Sweden)

    Full Text Available The article considers two modern works which employ the Antigone myth. The Polish film director Andrzej Wajda included several implicit allusions to the myth in his Katyn (2007,a film about the mass murder of Polish officers and intelligentsia – a Soviet crime which remained a taboo for almost half a century. On the other hand, Dominik Smole, a Slovenian playwright, wrote a play about Antigone (1960, which is set from beginning to end in ancient Thebes. It has been suggested that his play indirectly calls attention to the Slovenian post-war killings of the Slovenian Home Guard members, which were likewise long tabooed. Inquiring how the two works relate to Sophocles’ Antigone, the article points out that Andrzej Wajda seems inspired not only by Sophocles’ ideas but also by his dramatic techniques. A scene that seems especially interesting in this respect presents Agnieszka (Antigone going to the theatre to sell her hair in order to buy a tombstone for her dead brother Piotr (Polyneikes. The action in the theatre is so full of metaphors and subtle imagery that it can be compared to one of the most compelling scenes in Sophocles’ Antigone (801—943. In the latter, Sophocles employs a popular ancient dramatic technique, incorporating ritual elements in the dramatic action in order to create an atmosphere rich in meanings and connotations. While Wajda’s film includes at least two other scenes which seem directly inspired by the dramaturgical composition of Sophocles’ tragedy, Dominik Smole does not appear to make much use of Sophoclean techniques. To both authors, however, Sophocles is a key reference for their characters, situations, and dilemmas; both the film and the play refer to the ancient tragedy either through similarities or differences established in relation to the ancient Antigone. With regard to the differences, Smole’s only new persona dramatis, the page who survives Antigone as her devoted follower, appears to be

    Full Text Available The volume edited by Dominik SCHRAGE documents the results of a research seminar held by the editor at the Department of Sociology, Technical University of Dresden, in the spring term of 2004 and fall term of 2004/05. The contributions are based mainly on discourse analysis of print media coverage of the Elbe flood in the summer of 2002. Topics include a reflection on the possibilities of implementing FOUCAULTian discourse theory within empirical research projects, as well as formal characteristics of the flood discourse, the mutual interference between the reports on the election campaigns for the Bundestag and on the flood, and finally the image of nature emerging within the flood discourse. The volume shows the potential of FOUCAULT's discourse analysis for current social events and outlines possible methodological implementations. Moreover, it is a recommended reading for those who are interested in changes in discursive structures within exceptional social circumstances in general and in the social framing of natural disaster in particular.

  11. Rapid planetesimal formation in turbulent circumstellar discs

    Johansen, Anders; Mac Low, Mordecai-Mark; Klahr, Hubert; Henning, Thomas; Youdin, Andrew

    2007-01-01

    The initial stages of planet formation in circumstellar gas discs proceed via dust grains that collide and build up larger and larger bodies (Safronov 1969). How this process continues from metre-sized boulders to kilometre-scale planetesimals is a major unsolved problem (Dominik et al. 2007): boulders stick together poorly (Benz 2000), and spiral into the protostar in a few hundred orbits due to a head wind from the slower rotating gas (Weidenschilling 1977). Gravitational collapse of the solid component has been suggested to overcome this barrier (Safronov 1969, Goldreich & Ward 1973, Youdin & Shu 2002). Even low levels of turbulence, however, inhibit sedimentation of solids to a sufficiently dense midplane layer (Weidenschilling & Cuzzi 1993, Dominik et al. 2007), but turbulence must be present to explain observed gas accretion in protostellar discs (Hartmann 1998). Here we report the discovery of efficient gravitational collapse of boulders in locally overdense regions in the midplane. The bou...

    2008-01-01

    We present a parameter study of self-consistent models of protoplanetary disks around Herbig AeBe stars. We use the code developed by Dullemond and Dominik, which solves the 2D radiative transfer problem including an iteration for the vertical hydrostatic structure of the disk. This grid of models will be used for several studies on disk emission and mineralogy in followup papers. In this paper we take a first look on the new models, compare them with previous modeling attempts and focus on the effects of various parameters on the overall structure of the SED that leads to the classification of Herbig AeBe stars into two groups, with a flaring (group I) or self-shadowed (group II) SED. We find that the parameter of overriding importance to the SED is the total mass in grains smaller than 25um, confirming the earlier results by Dullemond and Dominik. All other parameters studied have only minor influences, and will alter the SED type only in borderline cases. We find that there is no natural dichotomy between ...

    The Compact Linear Collider and the International Linear Collider will accelerate particles and create collisions in different ways. Nonetheless, the detector concepts under development share many commonalities.   Timepix chips under scrutiny in the DESY test beam with the help of the beam telescope. CERN physicist Dominik Dannheim explains that the CLIC detector plans are adaptations of the ILC detector designs with a few select modifications. “When we started several years ago, we did not want to reinvent the wheel,” says Dannheim. “The approved ILC detector concepts served as an excellent starting point for our designs.” Essential differences Both CLIC and ILC scientists foresee general-purpose detectors that make measurements with exquisite precision. These colliders, however, have very different operating parameters, which will have important consequences for the various detector components. The ILC’s collision energy is set at 500 GeV ...

    Like watching a balloon borne by the breeze, a Lagrangian model tracks a parcel of air as it flows through the atmosphere. Whether running forward or backward in time, Lagrangian models offer a powerful tool for tracking and understanding the fates, or origins, of atmospheric flows. In the AGU monograph Lagrangian Modeling of the Atmosphere, editors John Lin, Dominik Brunner, Christoph Gerbig, Andreas Stohl, Ashok Luhar, and Peter Webley explore the nuances of the modeling technique. In this interview Eos talks to Lin about the growing importance of Lagrangian modeling as the world settles on climate change mitigation strategies, the societal value of operational modeling, and how recent advances are making it possible to run these complex calculations at home.

    2005-01-01

    We examine the ``puffed-up inner disk'' model (Dullemond, Dominik & Natta 2001), proposed for explaining the near-IR excess radiation from Herbig Ae/Be stars. Detailed model re-computations and comparison with the observed distribution of near-IR excess show that the model requires fine tuning of free parameters. In particular, only perfectly gray dust opacity can produce the observed near-IR excess, yet such dust is in conflict with the observed 10$\\mu$m spectral feature. We find that an alternative model consisting of a compact ($\\sim$ 10 AU) tenuous dusty halo around the disk inner regions readily explains the observed near-IR excess. Furthermore, this model also resolves the puzzling relationship noted by Monnier and Millan-Gabet (2002) between luminosity and the interferometric inner radii of disks.

    The climate conference in Paris 2015 has resulted in ambitious goals to mitigate the extent of global climate warming within this century. In Germany, the expansion of renewable energy sources is without any alternative to match the own aims of greenhouse gas reductions. Therefore, in the German EEZ of the North Sea around 10 offshore wind farms (OWFs) are already working and more are currently planned or already under construction. At this already substantial level of offshore wind energy production little is known about the effects of OWFs on the pelagic ecosystem. Earlier investigations have shown an increase of benthic organisms settling on hard substrates provided by the power plant foundations. However, the effects of offshore power plants on lower trophic level organisms within the water column are poorly understood. Thus, we investigated the abundance and distribution of zooplankton within and around OWFs. The analysis was based on optical data derived from a Video Plankton Recorder (VPR). The VPR was mounted on a TRIAXUS system including a suite of different sensors, hence allowing to combine zooplankton information with ambient hydrographic parameters. The combination of the VPR and the TRIAXUS system enabled us to analyse continuous zooplankton and hydrographic data with a high spatial resolution. In this study, we present results of transects through the OWFs Global Tech I, BARD Offshore 1, and Alpha Ventus. The analysis exhibits distinct pattern in the spatial distribution both of physical state variables and of plankton organisms within the vicinity of OWFs, especially of meroplankton, the larval phase of benthic organisms.

    2012-01-01

    The central collision between two solid spheres or the normal collision between a sphere and a plate are important to understand in detail before studying more complex particle interactions. Models exist to describe this basic problem but are not always consistent with available experiments. An interesting benchmark to compare models and experiments is the relation between the normal coefficient of restitution e and the incident velocity v. In order to draw a broad comparison between experiments and models (Krijt, S., Tielens, A.G.G.M., G\\"uttler, C., Hei{\\ss}elmann, D., Dominik, C., Phys. Rev. E, submitted), we provide in this article an overview on the literature describing experiments on normal collisions, preferably providing data on e(v). We will briefly summarize our expectation on this relation according to an established collision model in order to classify these experiments. We will then provide an overview on experimental techniques, which we found in the summarized articles, as well as a listing of...

The most common cause of dizziness in the elderly, benign paroxysmal positional vertigo (BPPV, is frequently undiagnosed, and bedside treatment of these patients can be difficult due to neck and back stiffness, which makes repeated and accurate repositioning maneuvers difficult. Case presentation: After a fall, a 96-year-old woman was referred by a resident neurologist for intractable BPPV. The patient was placed on a motorized turntable and repositioned to remove the calcite particles from the affected posterior semicircular canal. Video monitoring of the eyes allowed confirmation of the diagnosis, as well as an immediate evaluation of the effectiveness of the maneuver. Conclusion: Every patient with dizziness or imbalance, even in the absence of typical complaints of BPPV, should be tested with provocation maneuvers, because the clinical picture of BPPV is not always typical. Even if elderly patients with dizziness are very frail, the completion of provocation maneuvers is imperative, since the therapeutic maneuvers are extremely effective. A motorized turntable is very helpful to perform the repositioning accurately and safely. Keywords: vestibulo ocular reflex, nystagmus, vertigo

    Young stars with masses 2-8 times solar, the Herbig Ae and Be stars, often show a near-infrared excess too large to explain with a hydrostatically supported circumstellar disk of gas and dust. At the same time, the accretion flow carrying the circumstellar gas to the star is thought to be driven by magnetorotational turbulence, which, according to numerical MHD modeling, yields an extended low-density atmosphere supported by the magnetic fields. We demonstrate that the base of the atmosphere can be optically thick to the starlight and that the parts lying near 1 AU are tall enough to double the fraction of the stellar luminosity reprocessed into the near-infrared. We generate synthetic spectral energy distributions (SEDs) using Monte Carlo radiative transfer calculations with opacities for submicron silicate and carbonaceous grains. The synthetic SEDs closely follow the median Herbig SED constructed recently by Mulders and Dominik and, in particular, match the large near-infrared flux, provided the grains have a mass fraction close to interstellar near the disk's inner rim.

Der Beitrag orientiert sich hierbei an ‚visionären‘ Einzelpersonen – wie Carl August Lückenrath oder Vannevar Bush –, welche die Entwicklung der ‚Digitalen Geschichtswissenschaften‘ prägten, immer noch prägen oder bis heute auf eine konstruktive Rezeption warten, und basiert auf einem Vortrag, der am 28.01.2012 während der studentischen Tagung „Wer Visionen hat, sollte zum Arzt gehen“ der Fachschaft Geschichte der Johannes Gutenberg-Universität Mainz gehalten wurde. Die Autoren schlagen in ihren Überlegungen die Brücke über die ‚Vision‘ hinter Skriptum und dem Komplex „studentisches Publizieren“ zu der an Manfred Thaller angelehnten Konzeption einer ‚historischen Workstation‘ und versuchen damit die für uns immer noch interessanten Aspekte der Diskussionen zu betonen und die verschiedenen Konzepte gleichzeitig wie einen konzeptuellen Spiegel zu gebrauchen, an dem die eigenen Visionen und Entwicklungen gemessen werden können.

    Observed protoplanetary disks consist of a large amount of micrometer-sized particles. Dullemond and Dominik (2005) pointed out for the first time the difficulty in explaining the strong mid-IR excess of classical T-Tauri stars without any dust-retention mechanisms. Because high relative velocities in between micrometer-sized and macroscopic particles exist in protoplanetary disks, we present experimental results on the erosion of macroscopic agglomerates consisting of micrometer-sized spherical particles via the impact of micrometer-sized particles. We find that after an initial phase, in which an impacting particle erodes up to 10 particles of an agglomerate, the impacting particles compress the agglomerate's surface, which partly passivates the agglomerates against erosion. Due to this effect the erosion halts within our error bars for impact velocities up to ~30 m/s. For larger velocities, the erosion is reduced by an order of magnitude. This outcome is explained and confirmed by a numerical model. In a n...

Small GTPases represent an important functional group of proteins that serve as molecular switches in a wide range of fundamental cellular processes, including intracellular transport, movement and signaling events. These proteins have further gained a special emphasis in cancer research, because within the last decades a huge variety of small GTPases from different subgroups could be related to the development of all types of tumors. Using a random forest approach, we were able to identify the most important amino acid positions for the classification process within the small GTPases superfamily and its subgroups. These positions are in line with the results of earlier studies and have been shown to be the essential elements for the different functionalities of the GTPase families. Furthermore, we provide an accurate and reliable software tool (GTPasePred to identify potential novel GTPases and demonstrate its application to genome sequences.Keywords: cancer, machine learning, classification, Random Forests, proteins

    Using the 3-telescope IOTA interferometer on Mt. Hopkins, we report results from the first near-infrared (lambda=1.65 mu) closure-phase survey of Young Stellar Objects (YSOs). These closure phases allow us to unambiguously detect departures from centrosymmetry (i.e., skew) in the emission pattern from YSO disks on the scale of ~4 milliarcseconds, expected from generic ``flared disk'' models. Six of fourteen targets showed small, yet statistically-significant, non-zero closure phases, with largest values from the young binary system MWC 361-A and the (pre-main sequence?) Be star HD 45677. Our observations are quite sensitive to the vertical structure of the inner disk and we confront the predictions of the ``puffed-up inner wall'' models of Dullemond, Dominik, and Natta (DDN). Our data support disks models with curved inner rims because the expected emission appear symmetrically-distributed around the star over a wide range of inclination angles. In contrast, our results are incompatible with the models posses...

A biopsychosocial perspective has proven a useful theoretical construct in other chronic pain conditions and was also started in MS. To support such an approach, we aimed to investigate pain in MS with special emphasis on separating quantitative and qualitative aspects, and its interrelation to behavioral and physical aspects.Materials and methods: Pain intensity (NRS and quality (SES were measured in 38 consecutive outpatients with MS (mean age, 42.0 ± 11.5 years, 82% women. Pain-related behavior (FSR, health care utilization, bodily complaints (GBB-24 and fatigue (WEIMuS were assessed by questionnaires, and MS-related neurological impairment by a standardized neurological examination (EDSS.Results: Mean pain intensity was 4.0 (range, 0–10 and mean EDSS 3.7 (range, 0–8 in the overall sample. Currently present pain was reported by 81.6% of all patients. Disease duration and EDSS did not differ between patients with and without pain and were not correlated to quality or intensity of pain. Patients with pain had significantly higher scores of musculoskeletal complaints, but equal scores of exhaustion, gastrointestinal and cardiovascular complaints. Pain intensity correlated only with physical aspects, whereas quality of pain was additionally associated with increased avoidance, resignation and cognitive fatigue.Conclusion: As in other conditions, pain in MS must be assessed in a multidimensional way. Further research should be devoted to adapt existing models to a MS-specific model of pain.Keywords: pain intensity, quality of pain, pain

Parathyroidectomy is often performed when medical therapy fails. The most common postoperative complication, hungry bone syndrome (HBS, requires early recognition and treatment. Materials and methods: A total of 84 patients who underwent parathyroidectomy because of secondary hyperparathyroidism were investigated. Detailed analysis of laboratory parameters (calcium, phosphate, parathyroid hormone, hemoglobin, and urea levels and baseline characteristics (age at time of surgery, duration of renal replacement therapy, and medication was performed to detect preoperative predictors for the development of HBS. Results: Average overall follow-up of the cohort was 4.7 years. Within this time frame, 13 of 84 patients had to undergo a second surgery because of recurrent disease, and HBS occurred in 51.2%. Only decreased preoperative calcium levels and younger age at time of surgery were significant predictors of HBS. Minimal levels of calcium were detected 3 weeks after surgery. Preoperative vitamin D therapy could not prevent HBS and could not shorten the duration of intravenous calcium supplementation. Conclusion: HBS is a very common complication after parathyroidectomy. Younger patients and patients with low preoperative calcium levels were at higher risk for the development of HBS. Remarkably, preoperative vitamin D therapy could not prevent HBS and had no

Dysfunction of the glutamatergic system plays an important and well-established role in the pathogenesis of schizophrenia. Agents with glutamatergic properties such as N-methyl-D-aspartate receptor coagonists (ie, glycine, D-cycloserine and glycine transporter type 1 inhibitors (eg, sarcosine, bitopertin are investigated in schizophrenia with special focus on negative and cognitive symptomatology. In this article, we describe a case of a 34-year-old woman with diagnosis of schizophrenia with persistent moderate negative and cognitive symptoms, a participant of the Polish Sarcosine Study (PULSAR treated with olanzapine (25 mg per day and venlafaxine (75 mg per day. During ten weeks of sarcosine administration (2 g per day the patient’s activity and mood improved, but in the following 2 weeks, the patient reported decreased need for sleep, elevated mood, libido and general activity. We diagnosed drug-induced hypomania and recommended decreasing the daily dose of venlafaxine to 37.5 mg per day, which resulted in normalization of mood and activity in about 1 week. After this change, activity and mood remained stable and better than before adding sarcosine, and subsequent depressive symptoms were not noted. We describe here the second case report where sarcosine induced important affect changes when added to antidepressive and antipsychotic treatment, which supports the hypothesis of clinically important glutamate–serotonin interaction.Keywords: MNDA receptor, glutamatergic system, serotoninergic system

In a situation of palliative treatment, both patients and their relatives experience diverse types of distress and burden. Little research has been done to identify the individual difficulties and resources for patients with advanced lung cancer and their relatives. Especially, standardized questionnaire-based exploration may not assess the specific distressing issues that pertain to each individual on a personal level. The purpose of this qualitative study is to explore and compare individual difficulties and resources for lung cancer patients and their relatives within the palliative care context.Methods: Data were collected by qualitative interviews. A total of 18 participants, nine patients diagnosed with advanced lung cancer (International Classification of Diseases, tenth edition, diagnosis C-34, stage IV starting or receiving palliative treatment and nine relatives, were interviewed. Data were interpreted through qualitative content analysis.Results: We identified four main categories of difficulties: communication and conflicts, home and everyday life, thinking about cancer, and treatment trajectory. In general, difficulties were related to interpersonal relationships as well as to impact of chemotherapy. Family

    Full Text Available Daniel Urban, Sebastian Ewen, Christian Ukena, Dominik Linz, Michael Böhm, Felix Mahfoud Department of Internal Medicine III, Cardiology, Angiology and Intensive Care Medicine, University Hospital of Saarland, Homburg, Saarland, Germany Abstract: Arterial hypertension is the most prevalent risk factor associated with increased cardiovascular morbidity and mortality. Although pharmacological treatment is generally well tolerated, 5%–20% of patients with hypertension are resistant to medical therapy, which is defined as blood pressure above goal (>140/90 mmHg in general; >130–139/80–85 mmHg in patients with diabetes mellitus; >130/80 mmHg in patients with chronic kidney disease despite treatment with ≥3 antihypertensive drugs of different classes, including a diuretic, at optimal doses. These patients are at significantly higher risk for cardiovascular events, in particular stroke, myocardial infarction, and heart failure, as compared with patients with nonresistant hypertension. The etiology of resistant hypertension is multifactorial and a number of risk factors have been identified. In addition, resistant hypertension might be due to secondary causes such as primary aldosteronism, chronic kidney disease, renal artery stenosis, or obstructive sleep apnea. To identify patients with resistant hypertension, the following must be excluded: pseudo-resistance, which might be due to nonadherence to medical treatment; white-coat effect; and inaccurate measurement technique. Activation of the sympathetic nervous system contributes to the development and maintenance of hypertension by increasing renal renin release, decreasing renal blood flow, and enhancing tubular sodium retention. Catheter-based renal denervation (RDN is a novel technique specifically targeting renal sympathetic nerves. Clinical trials have demonstrated that RDN significantly reduces blood pressure in patients with resistant hypertension. Experimental studies and small

Similarities and differences in perspectives were explored.Methods: Eight semistructured focus groups were conducted, four with type 2 diabetes patients (n=25 and four with both general practitioners (n=13 and health care assistants (n=10. Sessions were audio and video recorded, transcribed verbatim, and subjected to computer-aided qualitative content analysis.Results: Diabetes patients and HCPs broadly highlighted similar factors as enablers for satisfactory medication information delivery. Perceptions substantially differed regarding impeding factors. Both patients and HCPs perceived it to be essential to deliver tailored information, to have a trustful and continuous patient–provider relationship, to regularly reconcile medications, and to provide tools for medication management. However, substantial differences in perceptions related to impeding factors included the causes of inadequate information, the detail required for risk-related information, and barriers to medication reconciliation. Medication self-management was a prevalent topic among patients, whereas HCPs’ focus was on fulfilling therapy and medication management responsibilities

    Complex organic molecules are ubiquitous companions of young forming stars. They were first observed in hot cores surrounding high-mass protostars [e.g., 1], but have since also been detected in the environs of several low-mass counterparts [e.g., 2]. Recent studies have shown that colder envelopes and positions with impinging outflows may also glow with emission from complex organic species [e.g., 3, 4]. For this meeting, I would like to present physicochemical modeling results on the synthesis of complex organics in an envelope-cavity system that is subject to non-thermal processing. This includes wavelength-dependent radiative transfer calculations with RADMC [5] and a comprehensive gas-grain chemical network [6]. The results show that the morphology of such a system delineates three distinct regions: the cavity wall layer with time-dependent and species-variant enhancements; a torus rich in complex organic ices, but not reflected in gas-phase abundances; and the remaining outer envelope abundant in simpler solid and gaseous molecules. Within the adopted paradigm, complex organic molecules are demonstrated to have unique lifetimes and be grouped into early and late species [7]. Key chemical processes for forming and destroying complex organic molecules will be discussed. In addition, the results of adding newly experimentally verified routes [8] into the existing chemical networks will be shown.[1] Blake G. A., Sutton E. C., Masson C. R., Phillips T.

However, despite its benefits, the outcome of ELVR remains difficult to predict. We investigated whether clinical success could be predicted by emphysema distribution assessed by computed tomography scan and baseline perfusion assessed by perfusion scintigraphy. Data from 57 patients with no CV in the target lobe (TL were retrospectively analyzed after ELVR with valves. Pulmonary function tests (PFT, St George’s Respiratory Questionnaire (SGRQ, and 6-minute walk tests (6MWT were performed on patients at baseline. The sample was grouped into high and low levels at the median of TL perfusion, ipsilateral nontarget lobe (INL perfusion, and heterogeneity index (HI. These groups were analyzed for association with changes in outcome parameters from baseline to 3 months follow-up. Compared to baseline, patients showed significant improvements in PFT, SGRQ, and 6MWT (all P≤0.001. TL perfusion was not associated with changes in the outcome. High INL perfusion was significantly associated with increases in 6MWT (P=0.014, and high HI was associated with increases in forced expiratory volume in 1 second (FEV1, (P=0.012. Likewise, there were significant correlations for INL perfusion and improvement of 6MWT (r=0.35, P=0.03 and for HI and improvement in FEV1 (r=0.45, P=0.001.

(*)University of Applied Sciences Wiener Neustadt, Austria (+)FOTEC GmbH, Wiener Neustadt, Austria (+) Spaceteam, TU Wien, Austria (~) University Wien, Wien, Austria The QB50 project is an international project with the goal to send up to 50 Nanosatellites, a.k.a. CubeSat, into the Thermosphere. The scientific goal of this mission is to monitor over a period of up to nine months the prevailing conditions in this rather unknown part of Earth's atmosphere. Each of the 50 nanosatellites will be equipped with one of three possible scientific instruments: (i) a set of Langmuir probes, (ii) atomic oxygen measurement device, (iii) ion/neutral mass spectrometer. All satellites will be launched together and released in a string-of-pearls type fashion. It is predicted that the satellites will drift apart rather rapidly following the release. Therefore, the QB50 missions offers the possibility of a measurement grid in the thermosphere of unprecedented scope and accuracy. One of the satellites, named PEGASUS, is designed and build by a team of Austrian researches and students. PEGASUS will be equipped with the aforementioned Langmuir probes and will provide information about essential properties of the plasma in the thermosphere such as the electrontemperature and -density. In order to ensure the capability to collect and downlink the data over several months, PEGASUS requires about the same types of subsystems as one would find on large-scale satellites. This includes an attitude control system, an on-board computer, telecommunication devices, an electrical power systems allowing to harvest the solar power and either distribute or store it for later use, a thermal control system

The aim of our research was to analyze nutritional behaviors for the assessment of the risk of orthorexia. The authors developed a questionnaire in which 981 respondents participated and used it as a research method. Both men and women ate mostly 4–5 meals per day (46.30% women versus 34.74% men; however, more men than women ate 1–2 meals daily (18.95% men versus 7.9% women. Both place of birth and field of study did not differ in terms of the number of meals. Moreover, it was observed that the number of meals per day was correlated with the declared time spent on planning a diet. People who ate over 3 meals per day more often indicates that they spent >3 h per day on planning their diet in comparison with people who ate only 1–2 meals. Only 17.6% of the respondents declared that they most often ate meals in a company of someone, whereas 45.3% indicated that there was no rule. The remaining 37.1% of the respondents most often consumed their meals alone. Almost twice as many men as women never paid attention to the qualitative composition of nutrition. Women followed a slimming diet more often than men (20.3% versus 5.8% and this indicated >4 attempts of losing weight

This study aimed to determine the predictive factors for patients receiving education, making a decision, and receiving their preferred modality choice in UPS patients following a UPS educational program (UPS-EP. Methods: The Offering Patients Therapy Options in Unplanned Start (OPTiONS study examined the impact of the implementation of a specific UPS-EP, including decision support tools and pathway improvement on dialysis modality choice. Linear regression models were used to examine the factors predicting three key steps: referral and receipt of UPS-EP, modality decision making, and actual delivery of preferred modality choice. A simple economic assessment was performed to examine the potential benefit of implementing UPS-EP in terms of dialysis costs. Results: The majority of UPS patients could receive UPS-EP (214/270 patients and were able to make a decision (177/214, although not all patients received their preferred choice (159/177. Regression analysis demonstrated that the initial dialysis modality was a predictive

    Astronomers may have solved a cosmic chicken-and-egg problem -- the question of which formed first in the early Universe -- galaxies or the supermassive black holes seen at their cores. "It looks like the black holes came first. The evidence is piling up," said Chris Carilli, of the National Radio Astronomy Observatory (NRAO). Carilli outlined the conclusions from recent research done by an international team studying conditions in the first billion years of the Universe's history in a lecture presented to the American Astronomical Society's meeting in Long Beach, California. Gas in Distant Galaxy VLA image (right) of gas in young galaxy seen as it was when the Universe was only 870 million years old. CREDIT: NRAO/AUI/NSF, SDSS Full-size JPEG, 323 KB PDF file, 180 KB Galaxy image, no annotation, JPEG 21 KB Earlier studies of galaxies and their central black holes in the nearby Universe revealed an intriguing linkage between the masses of the black holes and of the central "bulges" of stars and gas in the galaxies. The ratio of the black hole and the bulge mass is nearly the same for a wide range of galactic sizes and ages. For central black holes from a few million to many billions of times the mass of our Sun, the black hole's mass is about one one-thousandth of the mass of the surrounding galactic bulge. "This constant ratio indicates that the black hole and the bulge affect each others' growth in some sort of interactive relationship," said Dominik Riechers, of Caltech. "The big question has been whether one grows before the other or if they grow together, maintaining their mass ratio throughout the entire process." In the past few years, scientists have used the National Science Foundation's Very Large Array radio telescope and the Plateau de Bure Interferometer in France to peer far back in the 13.7 billion-year history of the Universe, to the dawn of the first galaxies. "We finally have been able to measure black-hole and bulge masses in several galaxies seen

The aim of our comparative study was to present the influence of two different nanoparticle types on subcellular processes of primary monocytes and the leukemic monocyte cell line MM6. We used core-shell starch-coated superparamagnetic iron oxide nanoparticles (SPIONs and matrix poly(lactic-co-glycolic acid (PLGA nanoparticles for our experiments. In addition to typical biocompatibility testing like the detection of necrosis or secretion of interleukins (ILs, we investigated the impact of these nanoparticles on the actin cytoskeleton and the two voltage-gated potassium channels Kv1.3 and Kv7.1. Induction of necrosis was not seen for PLGA nanoparticles and SPIONs in primary monocytes and MM6 cells. Likewise, no alteration in secretion of IL-1β and IL-10 was detected under the same experimental conditions. In contrast, IL-6 secretion was exclusively downregulated in primary monocytes after contact with both

    The upper Rhône basin (upstream of Lake Geneva) has been heavily affected by human activities during the last century. The most evident impacts are related to river regulation, specifically flow impoundement, flow abstraction and channelization. In the last century and mainly since 1960, several large dams have been built along the main tributaries of the Rhône River, resulting in the water storage of a volume equal to 20% of the total annual river flow. The dams are part of hydropower systems which abstract water from streams and transfer it through complex networks (intakes, tunnels and pumping stations) to the reservoirs. Hydropower production leads to regulated flow in the Rhône: mostly an increase of winter flows, a reduction of summer flows, and a decrease of flood peaks. The sediment supply into Lake Geneva has decreased following dam construction (Loizeau & Dominik, 2000) due to the storage of sediment in upstream reservoirs, in rivers with reduced sediment transport capacity due to flow abstraction, and due to the development of sediment mining. Our hypothesis is that streamflow regulation itself has dramatically impacted the sediment transport dynamics of the system. We investigate the impacts of flow regulation on the sediment transport regime, by analysing the effects on potential sediment transport capacity (bedload). By the use of different bedload transport formulae (Meyer-Peter Müller, Wilcock and Crowe), the potential sediment transport capacity is computed at different cross sections within the basin. Potential sediment mobility occurs when the applied bed shear stress exceeds a critical value, τ>τc. The applied bed shear stress is computed as τ=ρghS, with water depth (h) measured from rating curves. We obtain an estimate of the energy slope (S) from the analysis of the river cross section, assuming uniform flow. The critical value of bed shear stress τc is computed using empirical formulae as a function of the grain diameter (ds). To

  18. Cosmic Lens Reveals Distant Galactic Violence

    By cleverly unraveling the workings of a natural cosmic lens, astronomers have gained a rare glimpse of the violent assembly of a young galaxy in the early Universe. Their new picture suggests that the galaxy has collided with another, feeding a supermassive black hole and triggering a tremendous burst of star formation. Gravitational Lens Diagram Imaging a Distant Galaxy Using a Gravitational Lens CREDIT: Bill Saxton, NRAO/AUI/NSF Click on image for details and more graphics. The astronomers used the National Science Foundation's Very Large Array (VLA) radio telescope to look at a galaxy more than 12 billion light-years from Earth, seen as it was when the Universe was only about 15 percent of its current age. Between this galaxy and Earth lies another distant galaxy, so perfectly aligned along the line of sight that its gravity bends the light and radio waves from the farther object into a circle, or "Einstein Ring." This gravitational lens made it possible for the scientists to learn details of the young, distant galaxy that would have been unobtainable otherwise. "Nature provided us with a magnifying glass to peer into the workings of a nascent galaxy, providing an exciting look at the violent, messy process of building galaxies in the early history of the Universe," said Dominik Riechers, who led this project at the Max Planck Institute for Astronomy in Germany and now is a Hubble Fellow at the California Institute of Technology (Caltech). The new picture of the distant galaxy, dubbed PSS J2322+1944, shows a massive reservoir of gas, 16,000 light-years in diameter, that contains the raw material for building new stars. A supermassive black hole is voraciously eating material, and new stars are being born at the rate of nearly 700 Suns per year. By comparison, our Milky Way Galaxy produces the equivalent of about 3-4 Suns per year. The black hole appears to be near the edge, rather than at the center, of the giant gas reservoir, indicating, the astronomers say

    written by Slovene dramatists are rarely inspired by whole scenes or passages from Shakespeare's plays, although there are also some exceptions from this rule. It is rather surprising how quickly Slovene theatres produced works written by important foreign dramatists already in the period following the First World War not to mention how quickly plays written by the best European and American playwrights have appeared on Slovene stages during the past fifty years. The connection between Shakespeare's plays and plays written by Slovene playwrights became more subtle, more sophisticated, they are often based on implied symbolic references, which have become a starting point for a new interpretation of the world, particularly if compared with the Renaissance humanistic values. The sheer number of plays written by Slovene dramatists in this period makes it difficult to ascertain that all influences from Shakespeare's plays have been noticed, although it is hoped that all major borrowings and allusion are included. Slovene dramatists and theatre directors have provided numerous adaptations of Shakespeare's plays, which sometimes present a new version of an old motif so that it may hardly be linked with Shakespeare. Slovene artists, playwrights and 4 also theatre directors, have %rewritten%, %reset% the original text and given it a new meaning and/or a new form, and in a combination of motifs and structure they have thus created a %new play%, even stand-up comedies in which the actor depends on a scenario based on Shakespeare's play(s but every performance represents a new improvisation. Such productions are naturally closer to the commedia dell'arte type of play than to a play written by Shakespeare. I briefly mention such experimental productions in the introductory part of my study. The central part of my research deals with authors in whose works traces of Shakespeare's influence are clearly noticeable. These playwrights are: Matej Bor, Jože Javoršek, Ivan Mrak, Dominik

Diese Verteilung spiegelt das Gewicht der Schwerpunkte innerhalb des aktuellen Diskurses über den Zusammenhang von Computerspielen und Lernen/Bildung durchaus angemessen wider. Dominik Petko fokussiert auf formelle Lern- und Bildungskontexte und behandelt die Frage, welche didaktischen Potenziale Computerspiele für den gezielten Einsatz in Schule und Ausbildung aufweisen. Ausgangspunkt ist die Überlegung, dass es für den schulischen Bereich nicht ausreicht, die allgemeinen Lernpotenziale der Spiele auszuweisen und die Muster des spielimmanenten Lernens nachzuzeichnen, wie dies in einigen Publikationen der letzten Jahre geschehe. Um einen Schritt weiterzukommen und zu erreichen, dass digitale Spiele tatsächlich vermehrt in den Unterricht integriert werden, komme es darauf an, den Lehrpersonen zu zeigen, dass der Einsatz solcher Spiele einerseits mit einem vertretbaren Aufwand möglich ist und andererseits zu einem erkenn- und begründbaren Mehrwert führt. Dazu sei im ersten Schritt eine genauere Analyse und Typisierung der Spiele und anschliessend eine Konkretisierung der didaktischen Strategien und Arrangements für die sinnvolle Einbettung in den Unterricht erforderlich. Der Beitrag vermittelt einen ersten systematischen Überblick über entsprechende mediendidaktische Ziele und Ansätze für den Einsatz von Computerspielen in Schule und Unterricht.
