    The International Myeloma Working Group has proposed the Revised International Staging System (R-ISS) for risk stratification of multiple myeloma (MM) patients. There are a limited number of studies that have validated this risk model in the autologous stem cell transplant (ASCT) setting. In this retrospective study, we evaluated the applicability and value for predicting survival of the R-ISS model in 134 MM patients treated with new agents and ASCT at the Mayo Clinic in Arizona and the University Hospital of Salamanca in Spain. The patients were reclassified at diagnosis according to the R-ISS: 44 patients (33%) had stage I, 75 (56%) had stage II, and 15 (11%) had stage III. After a median follow-up of 60 months, R-ISS assessed at diagnosis was an independent predictor for overall survival (OS) after ASCT, with median OS not reached, 111 and 37 months for R-ISS I, II and III, respectively (P R-ISS II and having high-risk chromosomal abnormalities (CA) had a significant shorter median OS than those with R-ISS II without CA: 70 vs. 111 months, respectively. Therefore, this study lends further support for the R-ISS as a reliable prognostic tool for estimating survival in transplant myeloma patients and suggests the importance of high-risk CA in the R-ISS II group.

  4. FPGA-based real-time embedded system for RISS/GPS integrated navigation. (United States)

    Abdelfatah, Walid Farid; Georgy, Jacques; Iqbal, Umar; Noureldin, Aboelmagd


    Navigation algorithms integrating measurements from multi-sensor systems overcome the problems that arise from using GPS navigation systems in standalone mode. Algorithms which integrate the data from 2D low-cost reduced inertial sensor system (RISS), consisting of a gyroscope and an odometer or wheel encoders, along with a GPS receiver via a Kalman filter has proved to be worthy in providing a consistent and more reliable navigation solution compared to standalone GPS receivers. It has been also shown to be beneficial, especially in GPS-denied environments such as urban canyons and tunnels. The main objective of this paper is to narrow the idea-to-implementation gap that follows the algorithm development by realizing a low-cost real-time embedded navigation system capable of computing the data-fused positioning solution. The role of the developed system is to synchronize the measurements from the three sensors, relative to the pulse per second signal generated from the GPS, after which the navigation algorithm is applied to the synchronized measurements to compute the navigation solution in real-time. Employing a customizable soft-core processor on an FPGA in the kernel of the navigation system, provided the flexibility for communicating with the various sensors and the computation capability required by the Kalman filter integration algorithm.

  5. Tightly coupled low cost 3D RISS/GPS integration using a mixture particle filter for vehicular navigation. (United States)

    Georgy, Jacques; Noureldin, Aboelmagd


    Satellite navigation systems such as the global positioning system (GPS) are currently the most common technique used for land vehicle positioning. However, in GPS-denied environments, there is an interruption in the positioning information. Low-cost micro-electro mechanical system (MEMS)-based inertial sensors can be integrated with GPS and enhance the performance in denied GPS environments. The traditional technique for this integration problem is Kalman filtering (KF). Due to the inherent errors of low-cost MEMS inertial sensors and their large stochastic drifts, KF, with its linearized models, has limited capabilities in providing accurate positioning. Particle filtering (PF) was recently suggested as a nonlinear filtering technique to accommodate for arbitrary inertial sensor characteristics, motion dynamics and noise distributions. An enhanced version of PF called the Mixture PF is utilized in this study to perform tightly coupled integration of a three dimensional (3D) reduced inertial sensors system (RISS) with GPS. In this work, the RISS consists of one single-axis gyroscope and a two-axis accelerometer used together with the vehicle's odometer to obtain 3D navigation states. These sensors are then integrated with GPS in a tightly coupled scheme. In loosely-coupled integration, at least four satellites are needed to provide acceptable GPS position and velocity updates for the integration filter. The advantage of the tightly-coupled integration is that it can provide GPS measurement update(s) even when the number of visible satellites is three or lower, thereby improving the operation of the navigation system in environments with partial blockages by providing continuous aiding to the inertial sensors even during limited GPS satellite availability. To effectively exploit the capabilities of PF, advanced modeling for the stochastic drift of the vertically aligned gyroscope is used. In order to benefit from measurement updates for such drift, which are

    Natural gas from porous rocks whirls the energy markets and geopolitical strategies upside down. America celebrates its 'shale gas turnaround' and may soon fulfil the Kyoto Protocol without having signed it ever. Germany is between fear and belief in the progress of 'Clean Fracking'. The treatment of fracking liquids by means of ultraviolet light enables the dispensation with biocides in order to prevent the growth of bacteria. The omission of petrochemical additives does not provide any satisfactory results. The gas yield significantly is worse. The purity requirement of the fracking process is still some way off.

    In this paper I discuss critically Mathias Risse's paper “Responsibility and Global Justice.” First, I argue that for Risse's pluralist account of the grounds of justice to hold together, there is need to presuppose a monist standpoint which ultimately contributes to grounding principles of justice. Second, I point out that Risse's understanding of obligations of accountability and justification is rather narrow in that it functions as an addendum to obligations of justice. Conversely, I will...

  3. Regional Innovation Strategies in the Czech Republic

    Directory of Open Access Journals (Sweden)

    Hájek Oldřich


    Full Text Available Lately, the concept of innovation has become a development mantra in the fierce global competition. Competition is not limited to firms; it is also relevant for territories. An observed trend which is not surprising is the number of support tools that have been developed to reinforce the position of territories and their actors in the innovation processes. Clusters and regional innovation systems are the most important of them. However, both are rather underdeveloped in the CEE countries, including the Czech Republic. Faced with this situation, a number of Czech regional authorities (Regions took measures to stimulate the process of creating cluster and regional innovation system (RISs. Hence, strategic planning in the form of regional innovation strategies has become an overarching concept. So far, eleven Czech Regions have elaborated on RISs and analysis of these documents was the main focus of this article. The main finding of this paper is that, there is an increasing quality of RISs in the Czech Republic. Moreover, some common and some differentiated features of RISs were also identified. Consequently, the paper emphasizes numerous problems of RISs that is perceived as a key barrier towards real regional innovation system.

  6. A Highly Reliable and Cost-Efficient Multi-Sensor System for Land Vehicle Positioning

    Directory of Open Access Journals (Sweden)

    Xu Li


    Full Text Available In this paper, we propose a novel positioning solution for land vehicles which is highly reliable and cost-efficient. The proposed positioning system fuses information from the MEMS-based reduced inertial sensor system (RISS which consists of one vertical gyroscope and two horizontal accelerometers, low-cost GPS, and supplementary sensors and sources. First, pitch and roll angle are accurately estimated based on a vehicle kinematic model. Meanwhile, the negative effect of the uncertain nonlinear drift of MEMS inertial sensors is eliminated by an H∞ filter. Further, a distributed-dual-H∞ filtering (DDHF mechanism is adopted to address the uncertain nonlinear drift of the MEMS-RISS and make full use of the supplementary sensors and sources. The DDHF is composed of a main H∞ filter (MHF and an auxiliary H∞ filter (AHF. Finally, a generalized regression neural network (GRNN module with good approximation capability is specially designed for the MEMS-RISS. A hybrid methodology which combines the GRNN module and the AHF is utilized to compensate for RISS position errors during GPS outages. To verify the effectiveness of the proposed solution, road-test experiments with various scenarios were performed. The experimental results illustrate that the proposed system can achieve accurate and reliable positioning for land vehicles.

  9. An Enhanced Error Model for EKF-Based Tightly-Coupled Integration of GPS and Land Vehicle's Motion Sensors. (United States)

    Karamat, Tashfeen B; Atia, Mohamed M; Noureldin, Aboelmagd


    Reduced inertial sensor systems (RISS) have been introduced by many researchers as a low-cost, low-complexity sensor assembly that can be integrated with GPS to provide a robust integrated navigation system for land vehicles. In earlier works, the developed error models were simplified based on the assumption that the vehicle is mostly moving on a flat horizontal plane. Another limitation is the simplified estimation of the horizontal tilt angles, which is based on simple averaging of the accelerometers' measurements without modelling their errors or tilt angle errors. In this paper, a new error model is developed for RISS that accounts for the effect of tilt angle errors and the accelerometer's errors. Additionally, it also includes important terms in the system dynamic error model, which were ignored during the linearization process in earlier works. An augmented extended Kalman filter (EKF) is designed to incorporate tilt angle errors and transversal accelerometer errors. The new error model and the augmented EKF design are developed in a tightly-coupled RISS/GPS integrated navigation system. The proposed system was tested on real trajectories' data under degraded GPS environments, and the results were compared to earlier works on RISS/GPS systems. The findings demonstrated that the proposed enhanced system introduced significant improvements in navigational performance.

    Within the framework of the poly project, the partial project 'Methodical Fundamentals and Computer Supported Risk Management' has developed two RISs (Risk Information Systems). The aim of the present book is to present the viewpoints gained in these new technologies and model formation attempts with which new RISs can be conceived and created. Because of the numerous new attempts, a compromise had to be made between the breadth and depth of the discussions whereby the breadth was preferred; which means that the aim is to define the broad range of RIS development as comprehensively as possible. The reader is meant to be motivated to think about the new technologies and their role in risk management. figs., tabs., refs

    Moppes, F.I. van; Hoogenband, C.R. van den; Meijer, F.


    Aus einem Studium der Literatur, chirurgischen Befunden und Untersuchungen an Leichen kann es als unwahrscheinlich angesehen werden, dass bei einer Fussverstauchung vom Inversionstyp ein Riss des vorderen tibiofibularen Ligraments haeufig zusammen mit einem Gelenkkapselriss und einem seitlichen Baenderriss auftritt. Entgegen der Beobachtung anderer Verfasser fanden wir, dass ein Riss des vorderen tibiofularen Ligaments in keiner Weise aus dem Vorhandensein oder Nichtvorhandensein folgender arthrographischer Befunde geschlossen werden konnte: a) kontrastfreie Zone, b) tibiofibularer Rezessus, oder c) beide zusammen. Ein Gelenkkapselriss kann angenommen werden, wenn Kontrastmittel aus dem Gelenk in das weiche Gewebe austritt, ohne unterhalb oder seitlich in den Aussenknoechel zu dringen. Ein Austritt des Kontrastmittels unterhalb und seitlich des Aussenknoechels deutet auf einen Riss des vorderen tabofibularen Ligaments hin. Die anatomischen Zusammenhaenge zwischen Bandverbindung, Gelenkkapsel, tibiofibularem Rezessus und dem vorderen talofibularen Ligament wurden an Leichen und waehrend der chirurgischen Eingriffe studiert. Ausbreitung des Kontrastmittels im weichen Gewebe wird wahrscheinlich bestimmt durch die Anordnung und Beschaedigung der Weichteile und durch die Groesse des entstandenen Haematoms und folgt dem Weg des kleinsten Widerstandes.

    There are limited data on which patients not treated with intravenous (IV) tissue-type plasminogen activator (tPA) due to mild and rapidly improving stroke symptoms (MaRISS) have unfavorable outcomes. Acute ischemic stroke (AIS) patients not treated with IV tPA due to MaRISS from January 1, 2009 to December 31, 2013 were identified as part of the Georgia Coverdell Acute Stroke Registry. Multivariable regression analysis was used to identify factors associated with a lower likelihood of favorable outcome, defined as discharge to home. There were 1614 AIS patients who did not receive IV tPA due to MaRISS (median National Institutes of Health stroke scale [NIHSS] 1], of which 305 (19%) did not have a favorable outcome. Factors associated with lower likelihood of favorable outcome included Medicare insurance status (odds ratio [OR]: .53, 95% confidence interval [CI]: .34-.84), arrival by emergency medical services (OR: .46, 95% CI: .29-.73), increasing NIHSS score (per unit OR: .89, 95% CI: .84-.93), weakness as the presenting symptom (OR: .50, 95% CI: .30-.84), and a failed dysphagia screen (OR: .43, 95% CI: .23-.80). During the study period, dysphagia screen identify a subgroup of patients who are more likely to have an unfavorable outcome. Whether IV tPA treatment can improve the outcome in this subgroup of patients needs to be evaluated in a randomized placebo-controlled trial. Copyright © 2016 National Stroke Association.

  19. Injuries observed in a prospective transition from traditional to minimalist footwear: correlation of high impact transient forces and lower injury severity. (United States)

    Salzler, Matthew J; Kirwan, Hollie J; Scarborough, Donna M; Walker, James T; Guarino, Anthony J; Berkson, Eric M


    Minimalist running is increasing in popularity based upon a concept that it can reduce impact forces and decrease injury rates. The purpose of this investigation is to identify the rate and severity of injuries in runners transitioning from traditional to minimalist footwear. The secondary aims were to identify factors correlated with injuries. Fourteen habitually shod (traditional running shoes) participants were enrolled for this prospective study investigating injury prevalence during transition from traditional running shoes to 5-toed minimalist shoes. Participants were uninjured, aged between 22-41 years, and ran at least twenty kilometers per week in traditional running shoes. Participants were given industry recommended guidelines for transition to minimalist footwear and fit with a 5-toed minimalist running shoe. They completed weekly logs for identification of injury, pain using Visual Analogue Scale (VAS), injury location, and severity. Foot strike pattern and impact forces were collected using 3D motion analysis at baseline, 4 weeks, and 12 weeks. Injuries were scored according to a modified Running Injury Severity Score (RISS). Fourteen runners completed weekly training and injury logs over an average of 30 weeks. Twelve of 14 (86%) runners sustained injuries. Average injury onset was 6 weeks (range 1-27 weeks). Average weekly mileage of 23.9 miles/week prior to transition declined to 18.3 miles/week after the transition. The magnitude of the baseline impact transient peak in traditional shoes and in minimalist shoes negatively correlated with RISS scores (r = -0.45, p = 0.055 and r = -0.53, p = 0.026, respectively). High injury rates occurred during the transition from traditional to minimalist footwear. Non-compliance to transition guidelines and high injury rates suggest the need for improved education. High impact transient forces unexpectedly predicted lower modified RISS scores in this population.

  1. Radio propagation through the turbulent interstellar plasma

    International Nuclear Information System (INIS)

    Rickett, B.J.


    The current understanding of interstellar scattering is reviewed, and its impact on radio astronomy is examined. The features of interstellar plasma turbulence are also discussed. It is concluded that methods involving the investigation of the flux variability of pulsars and extragalactic sources and the VLBI visibility curves constitute new techniques for probing the ISM. However, scattering causes a seeing limitation in radio observations. It is now clear that variation due to RISS (refractive interstellar scintillations) is likely to be important for several classes of variable sources, especially low-frequency variables and centimeter-wave flickering. 168 refs

    Full Text Available Thomas Risse y Kathryn Sikkink plantean en este texto la importancia del impacto de las normas internacionales en las políticas domésticas y proponen un “modelo en espiral” en cinco fases para comprender los cambios en la interiorización de los derechos humanos como norma por parte de los estados. Desarrollan una teoría que explica las etapas y los mecanismos a través de los cuales las normas internacionales generan cambios en el comportamiento de los actores internacionales y transnacionales, y que ayuda a comprender mejor el impacto general de las normas en la política internacional. Este proceso mediante el cual las normas internacionales son interiorizadas e implementadas domésticamente puede ser entendido según los autores como un proceso de socialización. In this article Thomas Risse y Kathryn Sikkink analyze the importance of international norms impact over domestic politics and propose a five phases “spiral model” to explain the changes in human rights internalization by the states. They develop a theoretical framework that explains the stages and mechanisms by which international norms promote changes in international and transnational actors behavior, and that serves to a better comprehension of the general norms impact over international politics. The process by which international norms are internalized and implented on the domestic level can be understood, according to the authors, as a socialization process.

    - und Bruchzaehigkeitsversuche bei Raumtemperatur wurde die Al-seitige lokale Heterogenitaet des Gefueges, der Haerte und Festigkeit als Kriterium fuer die Festlegung der Risspositionen in den Verbindungen herangezogen: Riss parallel zur Schweissnaht und Riss senkrecht zur Schweissnaht. Dabei wurde auch der Einfluss des Laserstrahlschweissens in den Warmauslagerungszustaenden T4 und T6 der Al-Legierung AA6056 auf die Ermuedungsrissausbreitung und Bruchzaehigkeit beurteilt. Die im Zustand T4 laserstrahlgeschweisste Verbindung wurde mit einer nachfolgenden Warmauslagerung in den Zustand T6 gebracht. Die im Zustand T6 laserstrahlgeschweisste Verbindung wurde nach einer definierten Kaltauslagerungsdauer getestet. Die Orientierung ''Riss parallel zur Schweissnaht'' wurde in 3 Bereichen auf der Al-Seite untersucht: an der Grenzflaeche zwischen AA6056 und Ti6Al4V, zwischen Fuegezone und Waermeeinflusszone (3 mm Abstand von der Grenzflaeche) und zwischen Waermeeinflusszone und Grundwerkstoff (7 mm Abstand von der Grenzflaeche). Obwohl sich an der Grenzflaeche sproedes TiAl{sub 3} gebildet hat, wurde keine Trennung oder Abloesung an der Grenzflaeche beobachtet. Insofern war die Bindequalitaet der laserstrahlgeschweissten Mischverbindung als gut zu bewerten. Allerdings war im Bereich der Grenzflaeche die Ermuedungsrissausbreitung schneller als in der Fuegezone und der Waermeeinflusszone und die Bruchzaehigkeit vergleichsweise gering. Instabiler Ermuedungsrissfortschritt wurde beobachtet, wenn sich der Riss senkrecht zur Schweissnaht von AA6056 in Richtung Ti6Al4V ausbreitet. Die Ergebnisse haben gezeigt, dass die Mischverbindung einen verbesserten Widerstand aufweist, wenn im T6-Zustand laserstrahlgeschweisst wird. (Abstract Copyright [2009], Wiley Periodicals, Inc.)

  6. The Wada Test: contributions to standardization of the stimulus for language and memory assessment

    Directory of Open Access Journals (Sweden)

    Mäder Maria Joana


    Full Text Available The Wada Test (WT is part of the presurgical evaluation for refractory epilepsy. The WT is not standardized and the protocols differ in important ways, including stimulus type of material presented for memory testing, timing of presentations and methods of assessment. The aim of this study was to contribute to establish parameters for a WT to Brazilian population investigating the performance of 100 normal subjects, without medication. Two parallel models were used based on Montreal Procedure adapted from Gail Risse's (MEG-MN,EUA protocol. The proportions of correct responses of normal subjects submitted to two parallel WT models were investigated and the two models were compared. The results showed that the two models are similar but significant differences among the stimulus type were observed. The results suggest that the stimulus type may influence the results of the WT and should be considered when constructing models and comparing different protocols.

    Yeun, Young-Ran


    [Purpose] This study performed an effect-size analysis of massage therapy for shoulder pain. [Subjects and Methods] The database search was conducted using PubMed, CINAHL, Embase, PsycINFO, RISS, NDSL, NANET, DBpia, and KoreaMed. The meta-analysis was based on 15 studies, covering a total of 635 participants, and used a random effects model. [Results] The effect size estimate showed that massage therapy had a significant effect on reducing shoulder pain for short-term efficacy (SMD: -1.08, 95% CI: -1.51 to -0.65) and for long-term efficacy (SMD: -0.47, 95% CI: -0.71 to -0.23). [Conclusion] The findings from this review suggest that massage therapy is effective at improving shoulder pain. However, further research is needed, especially a randomized controlled trial design or a large sample size, to provide evidence-based recommendations.

  11. Radiation-Induced Leiomyosarcoma of the Prostate after Brachytherapy for Prostatic Adenocarcinoma

    Directory of Open Access Journals (Sweden)

    Hiroto Horiguchi


    Full Text Available Radiation therapy (RTx has been employed as a curative therapy for prostatic adenocarcinoma. RTx-induced sarcomas (RISs are rare, late adverse events, representing less than 0.2% of all irradiated patients. RISs are more aggressive tumors than prostatic adenocarcinomas. Herein, we present a case with RTx-induced prostatic leiomyosarcoma after permanent brachytherapy for prostatic adenocarcinoma. A 69-year-old male presented with dysuria and gross hematuria. Six years previously, he had been diagnosed with localized prostate cancer and was treated by permanent brachytherapy. Urethroscopy showed stenosis by a tumor at the prostate. Transurethral prostatectomy was performed for a diagnosis. Based on pathological findings, the diagnosis was leiomyosarcoma of the prostate. He was treated with three cycles of neoadjuvant chemotherapy (CTx that consisted of doxorubicin and ifosfamide (AI, followed by a prostatocystectomy with intrapelvic lymphadenectomy. The tumor extended from the prostate and infiltrated the bladder wall and serosa with lymphatic and venous invasion. The surgical margin was negative, and no residual prostatic adenocarcinoma was observed. The proportion of necrotic tumor cells by neoadjuvant CTx was around 50%. Subsequently, adjuvant CTx was offered, but the patient chose a follow-up without CTx. Local recurrence and lung metastasis were detected by computed tomography 3 months after the surgery. He was treated again with AI. However, CTx was not effective and he died 6 months after the operation. In conclusion, an effective treatment strategy for prostatic sarcoma should be developed in the near future, although the clinical feature of prostatic sarcoma remains unclear due to its rare incidence.

Para ello, evaluamos el fenómeno de la fragmentación explicada en términos de «fallos de sistema», los cuales habían sido descritos de forma fundamentalmente teórica. Por el contrario, nuestra aproximación emplea cuatro conjuntos de indicadores cuantitativos integrados en un marco interpretativo formado por los principales subsistemas del SRI. Así, los denominados: «brechas directivas», «brechas estructurales », «brechas de innovación» y el «valle de la muerte», son situados en el marco presentado para ser posteriormente analizados sobre los SRI de las Comunidades Autónomas españolas a partir de indicadores basados en datos explotados ad hoc por parte del Instituto Nacional de Estadística (INE y de la Asociación Española de Entidades de Capital Riesgo (ASCRI. Simplificamos la dimensionalidad de la tabla resultante a través de la aplicación de técnicas multivariantes como el Análisis Factorial Múltiple (AFM o el análisis clúster, las cuales nos conducen a la presentación de una nueva tipología para el caso de España.

  14. Molecular systematics and phylogeography of the genus Lagothrix (Atelidae, Primates) by means of the mitochondrial COII gene. (United States)

    Ruiz-Garcia, Manuel; Pinedo-Castro, Myreya Omayra


    We propose the first molecular systematic hypothesis on the origin and evolution of Lagothrix taxa based on an analysis of 720 base pairs of the cytochrome c oxidase subunit II mitochondrial gene in 97 Lagothrix specimens. All the current Lagothrix forms probably descended from the ancestor L. poeppigii or perhaps (less probably) that of L. lugens. We detected at least 2 lineages in L. poeppigii. L. cana and L. lagotricha were determined to be monophyletic and had lower gene diversity levels compared to L. poeppigii and L. lugens. The most basal ancestors of the current L. poeppigii lineages diverged from the other Lagothrix taxa around 2.5 million years ago, at the end of the Pliocene or at the beginning of the Pleistocene. Clearly, L. cana and L. lagotricha were the 2 most recently derived Lagothrix taxa. The diversification within L. lugens and L. poeppigii may coincide with the first and second Pleistocene glacial periods, respectively, while the diversification within L. cana and L. lagotricha could have occurred in the last 400,000 years, coinciding with the climatological changes provoked by the Illinois-Riss (third) and Wisconsin-Würm (fourth) glaciations.

    A compact detection system was built for multi-angle inspection of pipes, consisting of a high-sensitivity radiometric line scanner and an ultrasonic manipulator. Improved flaw imaging quality is achieved with this system as compared to film radiography. Measurements have been carried out on site in a nuclear power plant and in a laboratory. Better flaw imaging quality was also achieved in the testing of water-filled pipes. Non-linear tomosynthesis was applied for processing and interpretation of measured data. The system delivers considerably better images of planary materials inhomogeneitites, (such as cracks and lack-of-bond defects).

  16. Seniors centre-based health intervention programmes in the United States and South Korea: A systematic review. (United States)

    Song, Misoon; Seo, Kyoungsan; Choi, Suyoung; Choi, Jeongshil; Ko, Hana; Lee, Soo Jin


    Despite the great need for health interventions among seniors centre participants, this matter has received little attention. This systematic review aimed to identify what types of health interventions are effective and feasible for seniors centre participants. MEDLINE, Ovid, CINAHL, Google Scholar, EMBASE, and RISS were searched. We searched for health intervention studies conducted in seniors centres published in English and Korean between 1990 and 2014. Of 907 screened articles, 22 studies of all types of experimental designs were selected. Selected studies were grouped by intervention domain: health promotion (n = 8), safety (n = 5), chronic disease management (n = 6), and comprehensive wellness (n = 3). Overall, 59.1% of the interventions were provided by nurses. The health interventions resulted in positive effects on seniors centre participants' knowledge, health behaviours, clinical indices, and hospitalization rates. Few studies reported on feasibility outcomes such as satisfaction and cost-effectiveness. Considering the impact and ease of access to older people at seniors centres, health interventions and services within seniors centres should be strengthened. There is potential for nursing to spearhead seniors centre health intervention programmes to enhance active ageing for participants. © 2017 John Wiley & Sons Australia, Ltd.

  17. [Review of meta-analysis research on exercise in South Korea]. (United States)

    Song, Youngshin; Gang, Moonhee; Kim, Sun Ae; Shin, In Soo


    The purpose of this study was to evaluate the quality of meta-analysis regarding exercise using Assessment of Multiple Systematic Reviews (AMSTAR) as well as to compare effect size according to outcomes. Electronic databases including the Korean Studies Information Service System (KISS), the National Assembly Library and the DBpia, HAKJISA and RISS4U for the dates 1990 to January 2014 were searched for 'meta-analysis' and 'exercise' in the fields of medical, nursing, physical therapy and physical exercise in Korea. AMSTAR was scored for quality assessment of the 33 articles included in the study. Data were analyzed using descriptive statistics, t-test, ANOVA and χ²-test. The mean score for AMSTAR evaluations was 4.18 (SD=1.78) and about 67% were classified at the low-quality level and 30% at the moderate-quality level. The scores of quality were statistically different by field of research, number of participants, number of databases, financial support and approval by IRB. The effect size that presented in individual studies were different by type of exercise in the applied intervention. This critical appraisal of meta-analysis published in various field that focused on exercise indicates that a guideline such as the PRISMA checklist should be strongly recommended for optimum reporting of meta-analysis across research fields.

  18. Congruence between distribution modelling and phylogeographical analyses reveals Quaternary survival of a toadflax species (Linaria elegans) in oceanic climate areas of a mountain ring range. (United States)

    Fernández-Mazuecos, Mario; Vargas, Pablo


    · The role of Quaternary climatic shifts in shaping the distribution of Linaria elegans, an Iberian annual plant, was investigated using species distribution modelling and molecular phylogeographical analyses. Three hypotheses are proposed to explain the Quaternary history of its mountain ring range. · The distribution of L. elegans was modelled using the maximum entropy method and projected to the last interglacial and to the last glacial maximum (LGM) using two different paleoclimatic models: the Community Climate System Model (CCSM) and the Model for Interdisciplinary Research on Climate (MIROC). Two nuclear and three plastid DNA regions were sequenced for 24 populations (119 individuals sampled). Bayesian phylogenetic, phylogeographical, dating and coalescent-based population genetic analyses were conducted. · Molecular analyses indicated the existence of northern and southern glacial refugia and supported two routes of post-glacial recolonization. These results were consistent with the LGM distribution as inferred under the CCSM paleoclimatic model (but not under the MIROC model). Isolation between two major refugia was dated back to the Riss or Mindel glaciations, > 100 kyr before present (bp). · The Atlantic distribution of inferred refugia suggests that the oceanic (buffered)-continental (harsh) gradient may have played a key and previously unrecognized role in determining Quaternary distribution shifts of Mediterranean plants. © 2013 The Authors.

  19. Direct U-series analysis of the Lezetxiki humerus reveals a Middle Pleistocene age for human remains in the Basque Country (northern Iberia). (United States)

    de-la-Rúa, Concepción; Altuna, Jesús; Hervella, Monserrat; Kinsley, Leslie; Grün, Rainer


    In 1964, a human humerus was found in a sedimentary deposit in Lezetxiki Cave (Basque Country, northern Iberia). The first studies on the stratigraphy, associated mammal faunal remains and lithic implements placed the deposits containing the humerus into the Riss glacial stage. Direct chronometric evidence has so far been missing, and the previous chronostratigraphic framework and faunal dating gave inconsistent results. Here we report laser ablation U-series analyses on the humerus yielding a minimum age of 164 ± 9 ka, corresponding to MIS 6. This is the only direct dating analysis of the Lezetxiki humerus and confirms a Middle Pleistocene age for this hominin fossil. Morphometric analyses suggest that the Lezetxiki humerus has close affinities to other Middle Pleistocene archaic hominins, such as those from La Sima de los Huesos at Atapuerca. This emphasizes the significance of the Lezetxiki fossil within the populations that predate the Neanderthals in south-western Europe. It is thus an important key fossil for the understanding of human evolution in Europe during the Middle Pleistocene, a time period when a great morphological diversity is observed but whose phylogenetic meaning is not yet fully understood.

  20. Study of I11-conditioning of Linac stereotactic irradiation subspaces using singular values decomposition analysis

    International Nuclear Information System (INIS)

    Platoni, K.; Lefkopoulos, D.; Grandjean, P.; Schlienger, M.


    A Linac sterotactic irradiation space is characterized by different angular separations of beams because of the geometry of the stereotactic irradiation. The regions of the stereotactic space characterized by low angular separations are one of the causes of ill-conditioning of the stereotactic irradiation inverse problem. The singular value decomposition (SVD) is a powerful mathematical analysis that permits the measurement of the ill-conditioning of the stereotactic irradiation problem. This study examines the ill-conditioning of the stereotactic irradiation space, provoked by the different angular separations of beams, using the SVD analysis. We subdivided the maximum irradiation space (MIS: (AA) AP x (AA) RL =180 x 180 ) into irradiation subspaces (ISSs), each characterized by its own angular separation. We studied the influence of ISSs on the SVD analysis and the evolution of the reconstruction quality of well defined three-dimensional dose matrices in each configuration. The more the ISS is characterized by low angular separation the more the condition number and the reconstruction inaccuracy are increased. Based on the above results we created two reduced irradiation spaces (RIS: (AA) AP x (AA) RL =180 x 140 and (AA) AP x (AA) RL =180 x 120 ) and compared the reconstruction quality of the RISs with respect to the MIS. The more an irradiation space is free of low angular separations the more the irradiation space contains useful singular components. (orig.)

    Full Text Available The article discusses the use and transformation of the American scientific concept "soft power" in official Russian and US foreign policy rhetoric with the methodological help of Habermas' communicative action theory and its adoption to IR by T. Risse. In mainstream IR the proliferation of the "soft power" concept is viewed in terms of ideological competition among states. The author argues that it is better to view this process as a form of international political deliberations on new forms of power in world politics. The article shows that there's no communicative action of US and Russia based on their tentative discussion of the "soft power" concept. On of reasons might be the lack of interest of both states for the concept as an ideological basis for cooperative actions. For Russia soft power in its classical form might be used towards its near abroad and probably BIC states. In dealings with western states Russian soft power turns into lobbyism and propaganda which is strictly not soft power. US under Obama have basically refuted the concept, having changed it for analytically meaningless "smart power". The conclusion is that communicative action requires prior existence of commutative rationality. This type of rationality is evident among postmodern states - the EU member states - and apparently absent among modern states such as Russia and US.

    Full Text Available Abstract Background Guasha is a therapeutic method for pain management using tools to scrape or rub the surface of the body to relieve blood stagnation. This study aims to systematically review the controlled clinical trials on the effectiveness of using Guasha to treat musculoskeletal pain. Methods We searched 11 databases (without language restrictions: MEDLINE, Allied and Complementary Medicine (AMED, EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL, Korean Studies Information (KSI, DBPIA, Korea Institute of Science and Technology Information (KISTI, KoreaMed, Research Information Service System (RISS, China National Knowledge Infrastructure (CNKI and the Cochrane Library. The search strategy was Guasha (OR scraping AND pain. Risk of bias was assessed with the Cochrane criteria (i.e. sequence generation, blinding, incomplete outcome measures and allocation concealment. Results Five randomized controlled trials (RCTs and two controlled clinical trials (CCTs were included in the present study. Two RCTs compared Guasha with acupuncture in terms of effectiveness, while the other trials compared Guasha with no treatment (1 trial, acupuncture (4 trials, herbal injection (1 trial and massage or electric current therapy (1 trial. While two RCTs suggested favorable effects of Guasha on pain reduction and response rate, the quality of these RCTs was poor. One CCT reported beneficial effects of Guasha on musculoskeletal pain but had low methodological quality. Conclusion Current evidence is insufficient to show that Guasha is effective in pain management. Further RCTs are warranted and methodological quality should be improved.

The review will be updated to inform and guide healthcare practice and policy. Trial registration number: PROSPERO 2018 CRD42018085205 PMID:29595669

  4. Phylogeography on the rocks: The contribution of current and historical factors in shaping the genetic structure of Chthamalus montagui (Crustacea, Cirripedia). (United States)

    Pannacciulli, Federica G; Maltagliati, Ferruccio; de Guttry, Christian; Achituv, Yair


    The model marine broadcast-spawner barnacle Chthamalus montagui was investigated to understand its genetic structure and quantify levels of population divergence, and to make inference on historical demography in terms of time of divergence and changes in population size. We collected specimens from rocky shores of the north-east Atlantic Ocean (4 locations), Mediterranean Sea (8) and Black Sea (1). The 312 sequences 537 bp) of the mitochondrial cytochrome c oxidase I allowed to detect 130 haplotypes. High within-location genetic variability was recorded, with haplotype diversity ranging between h = 0.750 and 0.967. Parameters of genetic divergence, haplotype network and Bayesian assignment analysis were consistent in rejecting the hypothesis of panmixia. C. montagui is genetically structured in three geographically discrete populations, which corresponded to north-eastern Atlantic Ocean, western-central Mediterranean Sea, and Aegean Sea-Black Sea. These populations are separated by two main effective barriers to gene flow located at the Almeria-Oran Front and in correspondence of the Cyclades Islands. According to the 'isolation with migration' model, adjacent population pairs diverged during the early to middle Pleistocene transition, a period in which geological events provoked significant changes in the structure and composition of palaeocommunities. Mismatch distributions, neutrality tests and Bayesian skyline plots showed past population expansions, which started approximately in the Mindel-Riss interglacial, in which ecological conditions were favourable for temperate species and calcium-uptaking marine organisms.

  5. Adverse events associated with metal contamination of traditional chinese medicines in Korea: a clinical review. (United States)

    Kim, Hyunah; Hughes, Peter J; Hawes, Emily M


    This study was performed to review studies carried out in Korea reporting toxic reactions to traditional Chinese medicines (TCMs) as a result of heavy metal contamination. PubMed (1966-August 2013) and International Pharmaceutical Abstracts (1965-August 2013) were searched using the medical subject heading terms of "Medicine, Chinese Traditional," "Medicine, Korean Traditional," "Medicine, Traditional," "Metals, Heavy," and "Drug Contamination". For Korean literature, Korea Med (, the Korean Medical Database (, National Discovery for Science Leaders (, Research Information Sharing Service (, and Google Scholar were searched using the terms "Chinese medicine," "Korean medicine," "herbal medicine," and "metallic contamination" in Korean. Bibliographies of case reports and case series, identified using secondary resources, were also utilized. Only literature describing cases or studies performed in Korea were included. Case reports identified clear issues with heavy metal, particularly lead, contamination of TCMs utilized in Korea. No international standardization guidelines for processing, manufacturing and marketing of herbal products exist. Unacceptably high levels of toxic metals can be present in TCM preparations. Health care providers and patients should be educated on the potential risks associated with TCMs. International advocacy for stricter standardization procedures for production of TCMs is warranted.

    This contribution demonstrates how a thermometric procedure might be applied to determine crack initiation during fatigue testing of joints at steel sheets. The procedure is based on the measurement of the temperature increase which is produced by the heat at the respective joint caused by deformation energy. Such investigations are aimed at detection of crack initiation before it becomes visible at the specimen surface. Thermografic measurements at different mechanical joints and resistance welded spots are compared and various applications are suggested. (orig.) [German] In diesem Beitrag wird gezeigt, wie sich ein thermometrisches Verfahren einsetzen laesst, um die Rissentstehung waehrend der Dauerschwingpruefung von Stahlblechen zu erfassen. Vergleichend werden Messungen an Proben, die durch Stanznieten, Clinchen und Widerstandspunktschweissen gefuegt wurden, gegenuebergestellt. Hierzu wird die am Fuegepunkt waehrend der Pruefung in Waerme umgewandelte Formaenderungsenergie kontinuierlich in Form der Temperaturerhoehung gemessen. Ziel dieser Untersuchungen ist es, solche Temperaturerhoehungen zur Erkennung der Rissentstehung zu verwenden, bevor der Riss die Blechoberflaeche erreicht hat und visuell erkennbar wird. Zudem werden verschiedene Anwendungsmoeglichkeiten vorgeschlagen. (orig.)

    Full Text Available Objectives: The epidemiological characteristics of breast cancer incidence by age group in Korean women are unique. This systematic review aimed to investigate the association between hormone replacement therapy (HRT and breast cancer risk in Korean women. Methods: We searched electronic databases such as KoreaMed, KMbase, KISS, and RISS4U as well as PubMed for publications on Korean breast cancer patients. We also conducted manual searching based on references and citations in potential papers. All of the analytically epidemiologic studies that obtained individual data on HRT exposure and breast cancer occurrence in Korean women were selected. We restricted the inclusion of case-control studies to those that included age-matched controls. Estimates of summary odds ratio (SOR with 95% confidence intervals (CIs were calculated using random effect models. Results: One cohort and five case-control studies were finally selected. Based on the heterogeneity that existed among the six studies (I-squared=70.2%, a random effect model was applied. The summary effect size of HRT history from the six articles indicated no statistical significance in breast cancer risk (SOR, 0.983; 95% CI, 0.620 to 1.556. Conclusions: These facts support no significant effect of HRT history in the risk of breast cancer in Korean women. It is necessary to conduct a pooled analysis.

KG, Ingelheim am Rhein, 3Boehringer Ingelheim Pharma GmbH & Co. KG, Biberach an der Riss, Germany Abstract: Idiopathic pulmonary fibrosis (IPF is the most common type of idiopathic interstitial pneumonia and is characterized by a poor prognosis, with an estimated 5-year survival of approximately 20%. Progressive and irreversible lung functional impairment leads to chronic respiratory insufficiency with a severely impaired quality of life. In the last 2 decades, novel treatments for IPF have been developed as a consequence of an increasing understanding of disease pathogenesis and pathobiology. In IPF, injured dysfunctional alveolar epithelial cells promote fibroblast recruitment and proliferation, resulting in scarring of the lung tissue. Recently, pirfenidone and nintedanib have been approved for the treatment of IPF, having shown efficacy to slow functional decline and disease progression. This article focuses on the pharmacologic characteristics and clinical evidence supporting the use of nintedanib, a potent small-molecule tyrosine kinase inhibitor, as therapy for IPF. After introducing the mechanism of action and pharmacokinetics, an overview of the safety and efficacy results from the most recent clinical trials of nintedanib in IPF is presented. Keywords: tyrosine kinase, disease progression, treatment outcome, usual interstitial pneumonia, therapeutics

  11. Study of two new methods of geochronometry: dating method of carbonaceous formations by U-series disequilibrium gamma spectrometry; ESR dating method of rich U-content fossil dental enamel

    International Nuclear Information System (INIS)

    Ma, Jean-Luc


    First, the U-series disequilibrium dating method was re-examined using non-destructive γ-spectrometry. A new low-background (≤ 10 ppb U- equivalent) Ge-HP γ-spectrometer has been used to date travertine with small U-content (∼ 0.1 ppm) and low (≤ 5%) Th/U , content, by comparison with old-limestone γ-spectra. Second, a new ESR dating method has been developed using fossil dental enamel which is rich in U-content (10 - 100 ppm). Both methods were applied to Arago Cave (Tautavel, France): - with an ionium-age of 120 ka (10%), the upper travertine seems to have been set up during the Riss-deglaciation period. - the high (∼ 50%) Th/U-content samples of the intermediate travertine are un-datable. - the ESR-age of EQUUS mosbachensis enamel is 400 ka (10%) for the G-soil of Arago. XXI H. erectus, and 600 ka (10%) for the Q-soil above (- 1 m) of the lower travertine of which Io-age is older than 350 ka. (author)

  12. Investigations on creep and creep fatigue crack behaviour for component assessment

    International Nuclear Information System (INIS)

    Gengenbach, T.; Klenk, A.; Maile, K.


    There are various methods to assess crack initiation and crack growth behaviour of components under creep and creep fatigue loading. The programme system HT-Riss has been developed to support calculations aimed to determine the behaviour of a crack under creep or creep-fatigue loading using methods based on stress-intensity factor K (e.g. the Two-Criteria-Diagram) or C*-Integral. This paper describes the steps which have to be performed to assess crack initiation and growth of a component using this programme system. First the size of the maximum initial defect in a specimen or in a component has to be estimated and the necessary fracture mechanics parameters have to be determined. Then the time for creep crack initiation and creep crack growth is calculated. Using these values a prediction of life time and necessary inspection intervals is possible. For exemplification the crack assessment of a component-like specimen and a component is shown. (orig.)

    Full Text Available El yacimiento de Lezetxiki (Gipuzkoa, Pais Vasco. España encierra en sus 10 m. de sedimentos una serie interesante de niveles musterienses culminados por otros del Paleolítico Superior. Son los niveles musterienses el objeto de este estudio. La excavación, dirigida por J.M. de Barandiaran entre 1956 y   1968 permitió establecer ocho niveles (I-VIII. Estudios multidisciplinares -sedimentológicos, paleontológicos, palinológicos, antropológicos e industriales-, nos permiten acercarnos a la historia de una de las más antiguas presencias humanas constatadas en el País Vasco. Este estudio pretende   situar Lezetxiki en los códigos metodológicos al uso integrándose en las referencias de las provincias culturales cántabra y aquitana. La secuencia musteriense de Lezetxiki se inicia en una fase   templada del Riss con la aparición de un húmero humano neardenthalense. El nivel VII acoge las primeras industrias humanas; presencias esporádicas en una época fría en la que dominan los restos de oso y otros carnívoros sobre los ungulados, caza habitual del hombre. El nivel VI refleja un momento templado y húmedo, con desarrollo de amplios bosques de frondosas. Un bagage de utensilios lítico y óseo muy variado relaciona este nivel con el Musteriense Típico, que debió desarrollarse en el interglaciar de Eém (Riss-Würm. Durante las oscilaciones del Würm antiguo se dan en Lezetxiki las ocupaciones del nivel V, frío en la base que contiene el material arqueológico, con industrias parecidas al nivel anterior aunque ahora se cazan especies menores, y el nivel IV que por primera vez refleja una frecuentación repetida de la cueva. La industria lítica es ahora distinta, mostrando piezas de bordes muy reaprovechados y dominio de raederas que adscriben este nivel al Charentiense. A destacar la presencia de reno, la permanencia de Pliomys lenki y el predominio de ciervo. Todavía son frecuentes los osos y los carnívoros lobo, zorro y

  14. Opportunities and risks of hydraulic fraction treatment of tight gas-carrying rocks in redbeds; Chancen und Risiken hydraulischer Fracbehandlungen von dichten Erdgasspeichergesteinen im Rotliegenden

    Buhrow, C. [BEB Erdgas und Erdoel GmbH, Hannover (Germany)


    In the last 20 years more and more hydraulic fraction treatments have been carried out in natural gas-carrying strata of the redbed. By pumping high-viscosity liquids into the rocks one attempts to control the fraction. Towards the end of the treatment the fraction is filled with a proppant in order to create a flow path with high permeability to the borehole after the pressure of the liquid drops. The trend moves from large-volume single fractures - more than 2000 cubic m of liquid as several tons of proppant were used in some cases -. to smaller fraction treatments consisting of a minimum of two fractures: the first one, which usually employs small amounts of liquid and proppant, serves to gain information on the deposit and its suitability for fraction treatment. The one or several fractures that follow serve to increase production or enlarge the drainage area. Ground pressure measurements can provide important information about the development of the fracture before, during and after fracturing. (orig.) [Deutsch] Seit ca. 20 Jahren werden vermehrt hydraulische Fracbehandlungen in den Erdgasspeichergesteinen des Rotliegenden durchgefuehrt. Durch Verpumpen von Fluessigkeiten hoher Viskositaet soll kontrolliert ein Riss `Frac` genannt, im Gebirge geschaffen werden. Dieser wird gegen Ende der Behandlung mit Stuetzmittel angefuellt, um nach Abfall des Fluessigkeitsdrucks einen bleibenden Fliessweg hoher Permeabilitaet zum Bohrloch zu schaffen. Dabei hat es eine Entwicklung von grossvolumigen Einzelfracs - in Einzelfaellen wurden mehr als 2.000 m{sup 3} Fluessigkeit und mehrere hundert Tonnen Stuetzmittel verpumpt - hin zu kleineren Fracbehandlungen aus zumindest zwei Fracs gegeben: Ziel des ersten, zumeist nur geringe Fluessigkeitsvolumina und Stuetzmittelmengen enthaltenen Fracs ist es, Informationen ueber die Lagerstaette und deren Fracbehandelbarkeit zu erlangen.

  15. Comparison of preferences of healthcare professionals and MS patients for attributes of disease-modifying drugs: A best-worst scaling. (United States)

    Kremer, Ingrid E H; Evers, Silvia M A A; Jongen, Peter J; Hiligsmann, Mickaël


    The choice between disease-modifying drugs (DMDs) for the treatment of multiple sclerosis (MS) becomes more often a shared decision between the patient and the neurologist and MS nurse. This study aimed to assess which DMD attributes are most important for the healthcare professionals in selecting a DMD for a patient. Subsequently, within this perspective, the neurologists' and nurses' perspectives were compared. Lastly, the healthcare professionals' perspective was compared with the patients' perspective to detect any differences that may need attention in the communication about DMDs. A best-worst scaling (BWS) was conducted among 27 neurologists and 33 MS nurses treating patients with MS to determine the importance of 27 DMD attributes. These attributes were identified through three focus groups with MS patients in a previous study (N=19). Relative importance scores (RISs) were estimated for each attribute. Multivariable linear regression analyses were used to compare the different perspectives. According to the neurologists and nurses, safety of the DMD was the most important DMD attribute in the treatment decision, closely followed by effect on disability progression, quality of life and relapse rate. Patients with MS agreed with the importance of the last three attributes, but valued safety significantly lower (b=-2.59, P<.001). This study suggests that, overall, neurologists and nurses regard the same DMD attributes as important as MS patients with the notable exception of safety. This study provides valuable information for the development of interventions to support shared decision making and highlights which attributes of DMDs may need additional attention. © 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd.

    We aimed to assess the effectiveness of massage as a treatment option for autism. We searched the following electronic databases using the time of their inception through March 2010: MEDLINE, AMED, CINAHL, EMBASE, PsycINFO, Health Technology Assessment, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Psychology and Behavioral Sciences Collection, 6 Korean medical databases (KSI, DBpia, KISTEP, RISS, KoreaMed, and National Digital Library), China Academic Journal (through China National Knowledge Infrastructure), and 3 Japanese medical databases (Journal@rchive, Science Links Japan, and Japan Science & Technology link). The search phrase used was "(massage OR touch OR acupressure) AND (autistic OR autism OR Asperger's syndrome OR pervasive developmental disorder)." The references in all located articles were also searched. No language restrictions were imposed. Prospective controlled clinical studies of any type of massage therapy for autistic patients were included. Trials in which massage was part of a complex intervention were also included. Case studies, case series, qualitative studies, uncontrolled trials, studies that failed to provide detailed results, and trials that compared one type of massage with another were excluded. All articles were read by 2 independent reviewers (M.S.L. and J-I.K.), who extracted data from the articles according to predefined criteria. Risk of bias was assessed using the Cochrane classification. Of 132 articles, only 6 studies met our inclusion criteria. One randomized clinical trial found that massage plus conventional language therapy was superior to conventional language therapy alone for symptom severity (P firm conclusions cannot be drawn. Future, more rigorous randomized clinical trials seem to be warranted. © Copyright 2011 Physicians Postgraduate Press, Inc.

  17. Quaternary Activity of the Monastir and Grombalia Fault Systems in the North‒Eastern Tunisia (Seismotectonic Implication) (United States)

    Ghribi, R.; Zaatra, D.; Bouaziz, S.


    The Monastir and Grombalia fault systems consist of three strands that the northern segment corresponds to Hammamet and Grombalia faults. The southern strand represents Monastir Fault also referred to as the Skanes-Khnis Fault. These NW-trends are observed continuously in the major outcropping features of north-eastern Tunisia including both the Cap Bon peninsula and the Sahel domain. Along the Hammamet Fault, the north-eastern strand of Grombalia fault system, left lateral drainage offset of amount 220 m is found in Fawara valley. To the South, the left lateral movement is occurred along the Monastir Fault based on 180 m of Tyrrhenian terrace displacement. Field observations supported by satellite images suggest that the Monastir and Grombalia fault systems appear to slip mostly laterally with components of normal dip slip. Assuming the development of the stream networks during the Riss-Würm interglacial (115000-125000 years) and the age of the Tyrrhenian terrace (121 ± 10 ka), the strike slip rates of the Hammamet and Monastir faults are calculated in the range of 1.5-1.8 mm/yr. There vertical slip rates are estimated to be 0.06 and 0.26 mm/yr, respectively. These data are consistent with the displacement rate in the Pelagian shelf (1-2 mm/yr) but they are below the convergence rate of African-Eurasian plates (8 mm/yr). Our seismotectonics study reveals that a maximum earthquake of Mw = 6.5 could occur every 470 years in the Hammamet fault zone and Mw = 6-every 263 years in the Monastir fault zone.

    Manual therapy is the non-surgical conservative management of musculoskeletal disorders using the practitioner's hands on the patient's body for diagnosing and treating disease. The aim of this study is to systematically review trial-based economic evaluations of manual therapy relative to other interventions used for the management of musculoskeletal diseases. Randomised clinical trials (RCTs) on the economic evaluation of manual therapy for musculoskeletal diseases will be included in the review. The following databases will be searched from their inception: Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Econlit, Mantis, Index to Chiropractic Literature, Science Citation Index, Social Science Citation Index, Allied and Complementary Medicine Database (AMED), Cochrane Database of Systematic Reviews (CDSR), National Health Service Database of Abstracts of Reviews of Effects (NHS DARE), National Health Service Health Technology Assessment Database (NHS HTA), National Health Service Economic Evaluation Database (NHS EED), CENTRAL, five Korean medical databases (Oriental Medicine Advanced Searching Integrated System (OASIS), Research Information Service System (RISS), DBPIA, Korean Traditional Knowledge Portal (KTKP) and KoreaMed) and three Chinese databases (China National Knowledge Infrastructure (CNKI), VIP and Wanfang). The evidence for the cost-effectiveness, cost-utility and cost-benefit of manual therapy for musculoskeletal diseases will be assessed as the primary outcome. Health-related quality of life and adverse effects will be assessed as secondary outcomes. We will critically appraise the included studies using the Cochrane risk of bias tool and the Drummond checklist. Results will be summarised using Slavin's qualitative best-evidence synthesis approach. The results of the study will be disseminated via a peer-reviewed journal and/or conference presentations

    Under the roof of SINTAP (Structural Integrity Assessment Procedures for European Industry), a European BRITE-EURAM project, a study is being carried out into the possibility of establishing on the basis of existing models a standard European flaw assessment method. The R6 Routine and the ETM are important, existing examples in this context. The paper presents the two methods, explaining their advantages and shortcomes as well as common features. Their applicability is shown by experiments with two pressure vessels subject to internal pressure and flawed by a surface crack or a through-wall crack, respectively. Both the R6 Routine and the ETM results have been compared with results of component tests carried out in the 1980s at TWI and are found to yield acceptable conservative, i.e. sufficiently safe, lifetime predictions, as they do not give lifetime assessments which unduly underestimate the effects of flaws under operational loads.

Eine zentrale Stellung kommt dabei Verfahren wie der R6-Routine und dem ETM zu. In der vorliegenden Arbeit wurden beide Methoden vorgestellt, wobei ihre Vor- und Nachteile, aber auch ihre Gemeinsamkeiten herausgearbeitet wurden. Die Anwendung wurde an zwei innendruckbelasteten Behaeltern mit Oberflaechen- bzw. wanddurchdringendem Riss demonstriert. Sowohl R6-Routine als auch ETM ergaben im Vergleich mit am TWI zu Beginn der 80er Jahre durchgefuehrten Bauteilexperimenten eine vertretbare konservative Vorhersage, d.h. eine nicht allzu grosse Unterschaetzung der ertragbaren Last der Bauteile.

    Katarina Bačić


    Full Text Available The purpose of this paper is to do research on regional conditions that are most conducive to maximising the positive effects of the implementation of “New industrial policy” (policy based on Smart specialisation strategy to regional competitiveness in Croatia. Rather than using the standard but fragmented system of counties, this small post-transition economy is first mapped into five regions following the concept of regional innovation systems (RISs. Essentially, RIS concept rests on an idea that interactions among regional agents lead to the creation of optimal innovation output, while policy based on Smart specialisation strategy in Croatia is a national policy that promotes creation of innovative products and services in five promising domains and 13 sub-thematic areas. Analysis is carried out in two steps, firstly using a data-driven approach employed in a multidimensional framework for assessing regional accessibility, absorptive capacity and diffusion of knowledge in the context of Smart specialisation strategy (S3 implementation. In the second step, the assumption of post-transition reliance on the external knowledge and technology in producing innovation output is examined via regional presence of high-technology firms, GDP per capita and international trade and investment variables and patents per 100.000 inhabitants using cluster analysis (Ward method. The results show that highly internationalised regions with higher density of hightechnology firms already produce relatively more innovation output per capita. With already favourable conditions in place, these progressive regions are most likely to reinforce their competitive advantages through the transformation of their economic structures enabled by implementation of S3.

Female Wistar rats were exposed to a cafeteria diet to induce obesity. Empagliflozin was dosed once daily (10, 30, and 60 mg/kg for 28 days. Combination studies were subsequently performed using a submaximal empagliflozin dose (10 mg/kg with either sibutramine or orlistat. Body weight, food, and water intake were recorded daily. The effect of drug treatment on glucose tolerance, relevant plasma parameters, and carcass composition was determined. Empagliflozin dose-dependently reduced body weight, plasma leptin, and body fat though increased urinary glucose excretion. The combination of empagliflozin and orlistat significantly reduced body weight compared to animals treated with either drug alone, and significantly improved glucose tolerance, plasma insulin, and leptin compared to vehicle-treated controls. The effect of sibutramine to improve glycemic control in an oral glucose-tolerance test was also significantly increased, with empagliflozin and combination treatment leading to a reduction in carcass fat greater than that observed with either drug alone. These data demonstrate that empagliflozin reduces body weight in cafeteria-fed obese rats. In combination studies, empagliflozin further improved the body-weight or body-fat loss of animals in comparison to orlistat or sibutramine alone. Such studies may indicate improved strategies for the treatment of obese patients with prediabetes or type 2 diabetes. Keywords

    Nuclear power plants are complex and technically elaborate systems whose aim is to produce electricity. They must meet the highest safety requirements. Within the reactors, nuclear reactions and radioactive transformations release energy which is used to evaporate water. The steam generated drives turbines that in turn are coupled with generators which convert the kinetic energy provided by the turbines into electrical energy. The process is easy to illustrate but difficult to control and requires technical equipment such as kilometre-long pipe systems. Austenitic steel is frequently used for this purpose because of its high strength and corrosion resistance. The individual pipe components are joined by welding. However, welds may contain hidden defects. Cracks, lack of fusion or pore nests that can remain undetected may have catastrophic consequences. Therefore, all welds in a nuclear power plant, without exception, must be checked. Approved non-destructive methods use ultrasound and X-ray. The technology developed at BAM is called TomoWELD.

  4. The mental health of married immigrant women in South Korea and its risk and protective factors: A literature review. (United States)

    Lee, Yeeun; Park, Subin


    Married immigrant women in South Korea undergo a wide array of psychosocial challenges in the process of adapting to a new culture and marriage with a Korean husband. For an integrative understanding of women's mental health status and to determine the key risk and protective factors, we systematically reviewed empirical articles about the mental health of married immigrant women. We searched and reviewed articles from nine online databases: PubMed, Scopus, PsycINFO, Embase, DBpia, KISS, KMbase, KoreaMed and RISS, which were published up until January 2017. We identified 38 quantitative studies that examined psychiatric symptoms and pertinent factors for this population. The relative risks of psychiatric symptoms among married immigrant women varied across diverse samples. We summarized the associated factors existing prior to and after marriage migration that may moderate their mental health consequences. We identified five key risk factors: acculturative stress, country of origin, family stress, domestic violence and extended family structure, and two protective factors: social support and marriage satisfaction, which were consistently supported by the included studies. With the paucity of prospective studies, longitudinal research is needed that addresses the long-term processes of married immigrant women's psychological adaptation and the underlying risk and protective factors at diverse settlement phases. Furthermore, we suggest that future research should focus on how women's personal attributes interact with macro-level, socio-cultural contexts, including familial relationship and the community social-support system. Future evidence-based policy and interventions should comprehensively address married immigrant women's socio-cultural, economic and mental health needs.

  5. On The Black Sea Surozhian (United States)

    Caraivan, Glicherie; Corneliu, Cerchia


    Some Black Sea researchers still support the idea of no other connection to the Mediterranean Sea between LGM and Karangatian Stage (Riss - Wurm). We try to clarify the source of these disagreements. C14 AMS age data (HERAS Project) made on undisturbed samples from a new Mamaia drilling hole where compared with the classical Black Sea stratigraphic schemes. A first transgressive event (Zone D) is found between 38.00 - 20.20 m depth. Zone D4 shows a fairly rapid rise of sea level, about 10 m below the present one indicating an inner shelf marine polyhaline environment. AMS age data show 14C ages between 53690 - 47359 y (MIS 1), corresponding to the "Surozhian Beds" of Popov. The "beach rock" from Zone E marks the decrease of the sea level after the maximum reached in Zone D4. Zone E mollusc shells AMS data, indicate 14C ages of 48724 - 44604 y, suggesting a long-time reworked material from the previous D4 zone sediments, and represents the beginning of the "regressive Tarkankutian" sequence.The Last Glacial Maximum (LGM) led to the retreat of the sea level down to about 100 m below the current one (27-17 ky BP), followed by an retreat of the shoreline to the present position. At the beginning of the Holocene - MIS 1 (8408-8132 cal. y BP), Black Sea brackish water level grew rapidly, up to -14 m below the present one (Zone F: 22, 57-20, 20 m). Zone F deposits could be correlated with the Bugazian strata. Then, a continuous rising of the Black Sea level is recorded up to a maximum of -2 m under the present one, about 6789 - 7063 cal. y BP, when a transgressive spurt ("Neolithic transgression") may have taken place. After that, given a weak Danubian sedimentary input, coastal erosion intensified. The coarse sandy sediments were reworked and pushed over the previous peat deposits, and suggest a classical "sedimentary regression", not a sea-level decrease. During the last 1.5 ky, sea level has risen towards the current one. Previous C14 dates from "Karangatian

  6. A new tool for rapid and automatic estimation of earthquake source parameters and generation of seismic bulletins (United States)

    Zollo, Aldo


    RISS S.r.l. is a Spin-off company recently born from the initiative of the research group constituting the Seismology Laboratory of the Department of Physics of the University of Naples Federico II. RISS is an innovative start-up, based on the decade-long experience in earthquake monitoring systems and seismic data analysis of its members and has the major goal to transform the most recent innovations of the scientific research into technological products and prototypes. With this aim, RISS has recently started the development of a new software, which is an elegant solution to manage and analyse seismic data and to create automatic earthquake bulletins. The software has been initially developed to manage data recorded at the ISNet network (Irpinia Seismic Network), which is a network of seismic stations deployed in Southern Apennines along the active fault system responsible for the 1980, November 23, MS 6.9 Irpinia earthquake. The software, however, is fully exportable and can be used to manage data from different networks, with any kind of station geometry or network configuration and is able to provide reliable estimates of earthquake source parameters, whichever is the background seismicity level of the area of interest. Here we present the real-time automated procedures and the analyses performed by the software package, which is essentially a chain of different modules, each of them aimed at the automatic computation of a specific source parameter. The P-wave arrival times are first detected on the real-time streaming of data and then the software performs the phase association and earthquake binding. As soon as an event is automatically detected by the binder, the earthquake location coordinates and the origin time are rapidly estimated, using a probabilistic, non-linear, exploration algorithm. Then, the software is able to automatically provide three different magnitude estimates. First, the local magnitude (Ml) is computed, using the peak-to-peak amplitude

Objective: We examined whether the treatment given for exacerbations predicted subsequent outcomes. Methods: This was a post-hoc analysis of 17,135 patients with COPD from TIOtropium Safety and Performance In Respimat® (TIOSPIR®. Patients treated with tiotropium with one or more moderate to severe exacerbations on study were analyzed using descriptive statistics, logistic and Cox regression analysis, and Kaplan–Meier plots. Results: Of 8,061 patients with moderate to severe exacerbation(s, demographics were similar across patients with exacerbations treated with antibiotics and/or steroids or hospitalization. Exacerbations treated with systemic corticosteroids alone or in combination with antibiotics had the highest risk of subsequent exacerbation (HR: 1.21, P=0.0004 and HR: 1.33, P<0.0001, respectively, and a greater risk of having a hospitalized (severe exacerbation (HR: 1.59 and 1.63, P<0.0001, respectively or death (HR: 1.50, P=0.0059 and HR: 1.47, P=0.0002, respectively compared with exacerbations treated

  13. Possible role of Rhodotorula sp. in the formation of jarosite in the AMD environment of Muskau Arch, Poland (United States)

    Jakus, Natalia; Chlebicki, Andrzej; Bożęcki, Piotr; Manecki, Maciej


    The Muskau Arch is situated in the west of Poland and in the east of Germany. This region is a belt formed by push and frontal moraines during the Middle-Polish (Riss) glaciation, especially during the Wartanian glaciation. The occurrence of glacier caused folding and forming the glacitectonic type of lignit deposits which were mined for over 150 years. Both open pit and underground mining methods has exposed metal sulfides (mainly pyrite) to air and water causing bio-oxidation. Due to this process the acidity of many reservoirs have increased significantly (pH values between 2 and 4). As a consequence of changes in the environment, new mineral phases precipitated from highly acid waters rich in, among others, various forms of Fe and S. Precipitation of ochreous minerals such as schwertmannite, goethite and jarosite was partly catalyzed by many various acidophilic and acid-tolerant microorganisms: bacteria, archaea and probably yeasts. Jarosite KFe33+(OH)6(SO4)2 can be precipitated both in abiotic conditions and as a by-product of the activity of living organisms. The example of biomineralization induced by fungi Purpureocillium lilacinum in similar AMD environment of Rio Tinto is reported (Oggerin et al, 2014). Recently, jarosite is also considered as a possible biosignature of life on Mars. The assessment of microbial participation in formation of jarosite is an elementary step in geomicrobiological and astrobiological research. Isolated by us Rhodotorula sp. is an unicellular pigmented yeast. Fungi from the genus Rhodotorula F.C. Harrison belong to Sporidiobolalas part of phylum Basidiomycota. They are common environmental inhabitants. Some species, known from Rio Tinto, can live in extreme acidic soils at pH of about 2 (Lopez-Archila et al, 2004). For the first time, authors isolated strain Rhodotorula sp. from surface precipitates in Ł ęknica region (Muskau Arch). This ochreous precipitate contains jarosite. The yeast might be an important factor in indirect

  14. Detrital thermochronology of Rhine, Elbe and Meuse river sediment (Central Europe): implications for provenance, erosion and mineral fertility (United States)

    Glotzbach, C.; Busschers, F. S.; Winsemann, J.


    Here we present detrital apatite fission track (AFT), zircon fission track (ZFT) and a few apatite (U-Th)/He (AHe) data of Middle Pleistocene to modern Rhine, Meuse and Elbe river sediments in order to resolve processes that control detrital age distributions (provenance, erosion and mineral fertility). We used a modelling approach to compare observed with theoretically predicted age distributions from an interpolated in situ AFT and ZFT age map. In situ cooling ages do show large differences in the Rhine drainage basin, facilitating the differentiation between different source regions. Inconsistencies between observed and theoretical age distributions of the Meuse and Elbe samples can be explained by mixing and reworking of sediments with different provenances (Meuse Middle Pleistocene terrace sediment) and a yet unexplored source region with old AFT ages (Elbe samples). Overall, the results show that detrital thermochronology is capable of identifying the provenance of Middle Pleistocene to modern sediments. The AFT age distributions of Rhine sediments are dominated ( 70%) by AFT ages representing the Alps. A possible explanation is higher erosion rates in the Alps as compared to areas outside the Alps. A Late Pleistocene sample from the Upper Rhine Graben contains apatite grains from the Molasse and Hegau volcanics, which we explain with a shift of the headwaters of the Rhine to the north as a result of intense Middle Pleistocene Riss glaciation. Contrary to the observed dominance of Alpine-derived AFT ages in Rhine sediments, the relative contribution of zircon ages with sources in the Alps is lower and significantly decreases downstream, suggesting a major source of zircons outside the Alps. This can be explained by increased zircon fertility of sediments derived from the Rhenish massif. Therefore, we conclude that erosion and mineral fertility are the main processes controlling detrital AFT and ZFT age distributions of the sampled river sediment. In case of

    Wagner, Thomas; Fritz, Harald; Stüwe, Kurt; Nestroy, Othmar; Rodnight, Helena; Hellstrom, John; Benischke, Ralf


    The transition zone of the Eastern Alps to the Pannonian Basin provides one of the best sources of information on landscape evolution of the Eastern Alpine mountain range. The region was non-glaciated during the entire Pleistocene. Thus, direct influence of glacial carving as a landscape forming process can be excluded and relics of landforms are preserved that date back to at least the Late Neogene. In this study, we provide a correlation between various planation surfaces across the orogen-basin transition. In particular, we use stream terraces, planation surfaces and cave levels that cover a vertical spread of some 700 m. Our correlation is used to show that both sides of the transition zone uplifted together starting at least about 5 Ma ago. For our correlation we use recently published terrestrial cosmogenic nuclide (TCN) burial ages from cave sediments, new optically stimulated luminescence (OSL) ages of a stream terrace and U-Th ages from speleothems. Minimum age constraints of cave levels from burial ages of cave sediments covering the last ~ 4 Ma are used to place age constraints on surface features by parallelizing cave levels with planation surfaces. The OSL results for the top section of the type locality of the Helfbrunn terrace suggest an Early Würm development (80.5 ± 3.7 to 68.7 ± 4.0 ka). The terrace origin as a penultimate gravel deposit (in classical Alpine terminology Riss) is therefore questioned. U-series speleothem ages from caves nearby indicate formation during Marine Isotope Stages (MIS) 5c and 5a which are both interstadial warm periods. As OSL ages from the terrace also show a time of deposition during MIS 5a ending at the MIS 5/4 transition, this supports the idea of temperate climatic conditions at the time of deposition. In general, tectonic activity is interpreted to be the main driving force for the formation and evolution of these landforms, whilst climate change is suggested to be of minor importance.

  16. Buildings classification from airborne LiDAR point clouds through OBIA and ontology driven approach (United States)

    Tomljenovic, Ivan; Belgiu, Mariana; Lampoltshammer, Thomas J.


    In the last years, airborne Light Detection and Ranging (LiDAR) data proved to be a valuable information resource for a vast number of applications ranging from land cover mapping to individual surface feature extraction from complex urban environments. To extract information from LiDAR data, users apply prior knowledge. Unfortunately, there is no consistent initiative for structuring this knowledge into data models that can be shared and reused across different applications and domains. The absence of such models poses great challenges to data interpretation, data fusion and integration as well as information transferability. The intention of this work is to describe the design, development and deployment of an ontology-based system to classify buildings from airborne LiDAR data. The novelty of this approach consists of the development of a domain ontology that specifies explicitly the knowledge used to extract features from airborne LiDAR data. The overall goal of this approach is to investigate the possibility for classification of features of interest from LiDAR data by means of domain ontology. The proposed workflow is applied to the building extraction process for the region of "Biberach an der Riss" in South Germany. Strip-adjusted and georeferenced airborne LiDAR data is processed based on geometrical and radiometric signatures stored within the point cloud. Region-growing segmentation algorithms are applied and segmented regions are exported to the GeoJSON format. Subsequently, the data is imported into the ontology-based reasoning process used to automatically classify exported features of interest. Based on the ontology it becomes possible to define domain concepts, associated properties and relations. As a consequence, the resulting specific body of knowledge restricts possible interpretation variants. Moreover, ontologies are machinable and thus it is possible to run reasoning on top of them. Available reasoners (FACT++, JESS, Pellet) are used to check

Dabei wird je nach Versuchsfuehrung entweder die Zeit bis zur Initiierung von Anrissen verkuerzt oder die Wachstumsgeschwindigkeit vorhandener Risse erhoeht. Dieser zu erwartende Einfluss des Mediums auf den Ermuedungsprozess wurde in den Anfaengen der Regulierung von Konstruktion und Auslegung von Bauteilen und Komponenten fuer Kernkraftwerke in den relevanten Regelwerken (z.B. ASME Boiler and Pressure Vessel Code, Section III) weltweit nicht explizit beruecksichtigt. Pauschal beruecksichtigt werden Umgebungseffekte dagegen in den entsprechenden da/dN-Risswachstumskurven des ASME Code, Section XI zur Bewertung des betrieblichen Verhaltens von Oberflaechenfehlern. Historisch betrachtet erfolgte in den Regelwerken die Festlegung der Vorgehensweise zur Komponentenauslegung allerdings lange vor dem gezielten experimentellen Nachweis der Umgebungseffekte auf Rissinitiierung und Risswachstum durch Ermuedung von Staehlen in Hochtemperaturwasser. Trotz dieser Erkenntnis ist es weltweit nicht zu generischen, systematischen Schaeden in Medium fuehrenden Systemen von Leichtwasserreaktoren (LWR) durch Korrosionsermuedung infolge von Fehlauslegung gekommen.

In diesem Beitrag werden Beispiele gezeigt, die die Orts- und Zeitaufloesung der Neutronenradiographie und -tomographie nutzen, um Wasserstoffverteilungen in und an Rissen zu visualisieren und zu quantifizieren. Die Messungen wurden an den Forschungsreaktoren BER II des HZB in Berlin und FRM II der Neutronenquelle Heinz Maier-Leibnitz in Garching durchgefuehrt.

    ;'activated'' osteoarthritis under standard therapy, unclear joint-pain and before any arthroscopy. (orig.) [German] Koxarthrosen gehoeren zu den am haeufigsten auftretenden Arthrosen. Es besteht eine geringe Praevalenz des maennlichen Geschlechts. Aetiologisch werden primaere and sekundaere Koxarthrosen unterschieden. Primaere (idiopathische) sind aetiologisch unklar, sekundaere beruhen auf bekannten Aetiologien (z. B. Uebergewicht, repetitive Traumen, Fehlstellung bzw. Fehlhaltung, Muskel bzw. Sehnenimbalanz etc.). Pathophysiologisch finden sich bei Arthrosen Knorpel-, Subchondralregion-, Synovialis-, Gelenkfluessigkeitsveraenderungen sowie Abnormitaeten in den periartikulaeren Muskeln. Waehrend im Knorpel stadienhaft oedematoese Schwellung, Defekt mit Riss, Fibrillation, Glatzenbildung und Knorpelregeneratbildung sowie Gelenkspaltverschmaelerung auftreten, zeigen sich subchondral kleinste Oedembildungen, Nekrosen, evtl. Mikrofrakturen und Demineralisation sowie die bekannten subchondralen Sklerosierungen, Zystenbildungen und osteophytaeren Neubildungen. In spaeterer Folge kommt es zu Deformierungen und Fehlstellung. Letztere Veraenderungen sind mittels konventionellen Roentgenaufnahmen, CT und MRT gut abgrenzbar.Von zunehmender Bedeutung ist heute auch die Diagnostik sog. Praearthrosen. Dazu zaehlen aetiologisch u. a. unterschiedliche Fehlstellungen, Fehlformen, evtl. Labrumpathologien sowie die oben genannten Sehnen- und Muskelimbalanzen.Koxarthrosen werden in 3 prognostisch unterschiedliche Typen differenziert, abhaengig von der Migration des Kopfes: die laterokraniale als haeufigste, die mediokaudale und die seltene axiale. Ihre Entstehung duerfte auf unterschiedliche Mechanismen zurueckgehen.Die bildgebende Diagnostik erfolgt beim Vorliegen einer entsprechenden klinischen Symptomatik. Basis der Bildgebung ist heute unveraendert das konventionelle Roentgenbild, gefolgt von CT und MRT. Zur Diagnostik der ''aktivierten Arthrose'' wird nach wie vor die

    Full Text Available The objective of this study was to determine the prevalence and intensity of gastrointestinal nematodes in winter-slaughtered reindeer during 2002-2004, from northern reindeer herding cooperatives in Finland. Ostertagia gruehneri of the abomasum was prevalent with low levels of infections in 100% of calves, (n = 53; mean ≈ 1300 worms per animal and in 98% of adults, (n = 41; mean ≈ 3900 worms per animal. There was no difference in the number of O. gruehneri between male and female calves. The proportion of O. gruehneri inhibited larvae was significantly higher in calves (81% than in adult reindeer (39% (P = 0.005. The intestinal nematodes, Nematodirus tarandi and Nematodirella longispiculata, were detected only in reindeer calves. The numbers of these worms did not differ between male and female calves, but there was a difference in abundance between sites. High prevalence and low intensity of gastrointestinal nematodes characterized the patterns of infection of the reindeer examined in this study. It is assumed that these infections are sub-clinical and would not contribute to productivity losses.Abstract in Finnish / Lyhennelmä:Ruuansulatuskanavan sukkulamatojen esiintyminen talvella teurastetuissa pohjoissuomalaisissa poroissa Tämän työn tavoitteena oli määrittää ruuansulatuskanavan sukkulamatojen prevalenssi ja tartunnan aste talvella teurastetuissa Suomen pohjoisten paliskuntien poroissa vuosina 2002-2004.

  4. Coupling rainfall observations and satellite soil moisture for predicting event soil loss in Central Italy (United States)

    Todisco, Francesca; Brocca, Luca; Termite, Loris Francesco; Wagner, Wolfgang


    The accuracy of water soil loss prediction depends on the ability of the model to account for effects of the physical phenomena causing the output and the accuracy by which the parameters have been determined. The process based models require considerable effort to obtain appropriate parameter values and their failure to produce better results than achieved using the USLE/RUSLE model, encourages the use of the USLE/RUSLE model in roles of which it was not designed. In particular it is widely used in watershed models even at the event temporal scale. At hillslope scale, spatial variability in soil and vegetation result in spatial variations in soil moisture and consequently in runoff within the area for which soil loss estimation is required, so the modeling approach required to produce those estimates needs to be sensitive to those spatial variations in runoff. Some models include explicit consideration of runoff in determining the erosive stresses but this increases the uncertainty of the prediction due to the difficulty in parameterising the models also because the direct measures of surface runoff are rare. The same remarks are effective also for the USLE/RUSLE models including direct consideration of runoff in the erosivity factor (i.e. USLE-M by Kinnell and Risse, 1998, and USLE-MM by Bagarello et al., 2008). Moreover actually most of the rainfall-runoff models are based on the knowledge of the pre-event soil moisture that is a fundamental variable in the rainfall-runoff transformation. In addiction soil moisture is a readily available datum being possible to have easily direct pre-event measures of soil moisture using in situ sensors or satellite observations at larger spatial scale; it is also possible to derive the antecedent water content with soil moisture simulation models. The attempt made in the study is to use the pre-event soil moisture to account for the spatial variation in runoff within the area for which the soil loss estimates are required. More

  5. QuakeUp: An advanced tool for a network-based Earthquake Early Warning system (United States)

    Zollo, Aldo; Colombelli, Simona; Caruso, Alessandro; Elia, Luca; Brondi, Piero; Emolo, Antonio; Festa, Gaetano; Martino, Claudio; Picozzi, Matteo


    The currently developed and operational Earthquake Early warning, regional systems ground on the assumption of a point-like earthquake source model and 1-D ground motion prediction equations to estimate the earthquake impact. Here we propose a new network-based method which allows for issuing an alert based upon the real-time mapping of the Potential Damage Zone (PDZ), e.g. the epicentral area where the peak ground velocity is expected to exceed the damaging or strong shaking levels with no assumption about the earthquake rupture extent and spatial variability of ground motion. The platform includes the most advanced techniques for a refined estimation of the main source parameters (earthquake location and magnitude) and for an accurate prediction of the expected ground shaking level. The new software platform (QuakeUp) is under development at the Seismological Laboratory (RISSC-Lab) of the Department of Physics at the University of Naples Federico II, in collaboration with the academic spin-off company RISS s.r.l., recently gemmated by the research group. The system processes the 3-component, real-time ground acceleration and velocity data streams at each station. The signal quality is preliminary assessed by checking the signal-to-noise ratio both in acceleration, velocity and displacement and through dedicated filtering algorithms. For stations providing high quality data, the characteristic P-wave period (τ_c) and the P-wave displacement, velocity and acceleration amplitudes (P_d, Pv and P_a) are jointly measured on a progressively expanded P-wave time window. The evolutionary measurements of the early P-wave amplitude and characteristic period at stations around the source allow to predict the geometry and extent of PDZ, but also of the lower shaking intensity regions at larger epicentral distances. This is done by correlating the measured P-wave amplitude with the Peak Ground Velocity (PGV) and Instrumental Intensity (I_MM) and by mapping the measured and

    . Zweitens wird bei rotationssymmetrischen Bauteilen, die mittels einer Axial-Rundnaht zu verschweissen sind, mit einem relativ einfachen Temperaturfeld, das durch Erwaermung des innen liegenden Fuegepartners vor und waehrend des Schweissens aufgebaut wird, ein Spannungsfeld erzeugt, das die Bildung von Heissrissen verhindert. Schliesslich konnte drittens ein heissrissfreies Laserstrahlschweissen des Stahls 1.4305 und der Nickelbasislegierung Udimet 720 bereits ohne den Einsatz zusaetzlicher Temperaturfelder erreicht werden. Die Grenzen der Einsetzbarkeit des Verfahrens bei Cr-Ni-Staehlen werden dann erreicht, wenn Quer-Heissrisse oder parallel zur Blechoberflaeche liegende Heissrisse entstehen. Die zur Vermeidung dieser Risse noetigen Druckspannungen in den Richtungen parallel zur Schweissnaht bzw. senkrecht zur Blechoberflaeche koennen mittels induktiver Erwaermung von der Blechoberseite aus nicht in der erforderlichen Groesse erzeugt werden. Ebenso stoesst das Verfahren an seine Grenzen, wenn Wiederaufschmelzungsrisse auftreten, was beim hier verwendeten Stahl 1.4435 der Fall war. Die Spannungen, die zur Verhinderung einer Rissoeffnung an den Korngrenzen der Waermeeinflusszone erforderlich waeren, konnten durch Temperaturfeld-Tailoring nicht erreicht werden. Die Moeglichkeit des heissrissfreien Schweissens des Stahls 1.4305 auch ohne Temperaturfeld-Tailoring ergibt sich hauptsaechlich aus dem primaer ferritischen Erstarrungsmodus des Stahls in der vorliegenden Legierungszusammensetzung. Ein industrieller Einsatz des Laserstrahlschweissens fuer diesen oft als nicht schweissbar klassifizierten Stahl erscheint moeglich, wenn bei der Legierungszusammensetzung auf niedrige Anteile der Austenitbildner Nickel, Kohlenstoff und Stickstoff Wert gelegt wird und damit eine stabil primaer ferritische Erstarrung erreicht wird. Fuer diesen Fall kommt es nicht zur Schwefelanreicherung an den Korngrenzen, wodurch die Bildung niedrigschmelzender Phasen und damit die Heissrissentstehung

  7. Using an extended 2D hydrodynamic model for evaluating damage risk caused by extreme rain events: Flash-Flood-Risk-Map (FFRM) Upper Austria (United States)

    Humer, Günter; Reithofer, Andreas


    at 20th of June 2012, based on open data sources of geology, soil and land use. The aim of FFRM is to provide an estimation of the damage risk caused by flash-floods for the whole of Upper Austria. To address the hazard, inundation depths were calculated with the extended 2D-model using design rains with an 100-year return period provided by the Environmental Ministry [7]. The potential damage was calculated using damage functions, which were derived from our experience from damage surveys of past events in Austria and according to guidelines for determination of cost-benefit-ratios for flood protection measures [8]. The greatest difficulty was to get appropriate data for the distribution of houses and industrial plants. Zoning plans provide good information on spatial distribution of residential, commercial and industrial areas, but does not contain information on the kind of industry, which is essential for estimating absolute damage values. To get a first idea detailed information from surveyed areas was intersected with the zoning plan, which provides an average damage in the respective zones. The first results can be found on and will be updated with the further development of the project.

    Directory of Open Access Journals (Sweden)

    Erwin Heurkens


    private actors inter-organize urban projects, consist of economics & politics, governance cultures, and planning systems and policies. Hence, institutional values are deeply rooted in social welfare models (Nadin & Stead, 2008. For instance, the differences between Anglo-Saxon and Rhineland model principles also determine public-private relationships. However, the process of neoliberalization (Hackworth, 2007 and subsequent adaptation of neoliberal political ideologies (Harvey, 2005 has created quite similar governance arrangements in Western countries. Nevertheless, institutional rules incorporated in planning systems, laws and policies often remain country-specific. But, market-oriented planning, involving ‘planners as market actors’ (Adams & Tiesdell, 2010 intervening and operating within market systems, have become the most commonly shared feature of contemporary Western urban development practices (Carmona et al., 2009. In this research, the project organization focuses on institutional aspects and interorganizational arrangements that structure Public-Private Partnerships (Bult-Spiering & Dewulf, 2002. It involves studying organizational tasks and responsibilities, financial risks and revenues, and legal rules and requirements. Inter-organizational arrangements condition the way public and private actors manage projects. Hence, such arrangements can be placed on a public-private spectrum (Börzel & Risse, 2002 which indicates different power relations in terms of public and private autonomy and dominance (Savitch, 1997 in making planning decisions. These public-private power relations are reflected in different Public-Private Partnership arrangements (Bennet et al., 2000 in urban development projects. As a result, in some contexts these partnerships arrangements are formalized into organizational vehicles or legal contracts, in others there is an emphasis on informal partnerships and interaction. The lack of management knowledge on private sector-led urban
