    CERN Bulletin

    The tram service to Meyrin will begin operation on 13 December. Several bus routes, including those with stops at CERN, will be modified as a result.   The tram service to Meyrin will begin operation on 13 December (photo © TPG) Extension of the tram line as far as Meyrin The tram service to Meyrin will be officially inaugurated on Saturday 12 December and will start operating the following day. From 13 December onwards the No. 14 and No. 16 trams will run from the Gravière tram stop in Meyrin to the usual terminus (see map), serving the Cornavin railway station along the way. Passengers wishing to travel on to CERN will be able to catch the No. 56 bus at the Vaudagne stop (the last-but-one stop on the tram line). Passengers from CERN wishing to travel to Geneva by public transport will need to take the No. 56 bus to Vaudagne, then catch the No. 14 or No. 16 tram into the city centre.

    Naznin, Farhana; Currie, Graham; Logan, David

    2018-01-01

    Melbourne, Australia has the largest tram/streetcar network in the world including the largest mixed traffic tram operating environment. Therefore, Melbourne tram drivers are responsible for controlling one of the heaviest vehicles on road ranging from shared tram lanes to exclusive tram lanes. In addition to different tram lane configurations, tram drivers need to follow different traffic signal phases at intersections including tram priority signals as well as need to serve passengers at various types of closely spaced tram stops. Despite all these challenges, no research has explored tram driver perceptions of the risk factors on different tram route road design configurations. Therefore, the aim of this study is to investigate how tram drivers' safety perceptions alter along various tram route sections, signal settings and stop configurations. A tram driver focus group approach was adopted for this research involving thirty tram drivers (4 female and 26 male drivers). The tram drivers' age ranged from 29 to 63 years, with an average age of 47.6 years (standard deviation of 10.1 years), and their experience of tram driving ranged from 1.17 to 31 years, with an average experience of 12.5 years (standard deviation of 10.2 years). The participating tram drivers perceived that the raised tram tracks and tramways with raised yellow curbing beside tracks are safer lane priority features on the Melbourne tram network compared to full-time, part-time and mixed traffic tram lanes. They regarded 'hook turns' as a safe form of tram signal priority treatment at intersections and platform tram stops as the safest tram stop design for all passengers among all other tram stop designs in Melbourne. Findings of this research could enhance the understanding of crash risk factors for different tram route features and thus can offer effective planning strategies for transit agencies to improve tram road safety.

    The study and the modeling of tram power networks require a system analysis. The use of several power-electronic converters in these networks significantly modifies both their topology and their function. Therefore, modeling methods developed in this thesis differ from traditional approaches, since a global analysis of a system should be linked with the study of its components.To satisfy the demands of the tram domain, this thesis develops modeling methods for transmission lines and transformers. Two levels of analysis are considered. Firstly, the tram power network is evaluated in relation to time. Secondly, an Iterative Harmonic Analysis (IHA) program is developed to compute the spectra of the system accurately. (author)

    2010-07-01

    This article reviews experience made with a flywheel-based energy storage system that was tested on part of Zurich's tram network. The aim of the six weeks of tests was to determine how much energy that is generated by the recuperation of braking energy can be temporarily stored to provide power for accelerating trams on the network. The article discusses the valuable knowledge gained during the tests. The basic ideas behind the tests and the goals aimed for are discussed, both concerning energy balances as well as other factors such as noise and electromagnetic emissions. The part of the tram line used for the tests is described and the results are discussed. Other power storage systems using flywheels and capacitors are reviewed.

  8. Trams and roadworks on the route de Meyrin

    CERN Multimedia

    2007-01-01

    The project to bring trams to CERN’s doorstep will require a lot of roadworks on the route de Meyrin, so traffic diversions and restrictions are to be expected. Traffic will be diverted away from the route de Meyrin as of the beginning of February 2008. Work on the future Cornavin-Meyrin-CERN tram route (TCMC) is progressing nicely. The first section up to Avanchet was inaugurated on 8 December but users will not be able to ride the tram all the way to CERN, via Meyrin Village and Cité de Meyrin, until 2010. Until then, all road users will have to be patient. To make room for the tram and to alleviate traffic flow in the centre of Meyrin Village, a 755-m long underpass will be constructed. Traffic coming from the centre of Geneva will enter the underpass at the Ecole de Golette and emerge at the Carrosserie de la Tour, having passed 15 metres below Meyrin Village centre. This "cut-and-cover" construction will entail traffic diversions via the rout...

    2017-09-01

    Rail vehicles in interaction with a railway structure induce vibrations that are propagating to surrounding structures and cause noise disturbance in the surrounding areas. Since tram tracks in urban areas often share the running surface with road vehicles one of top priorities is to achieve low maintenance and long lasting structure. Research conducted in scope of this paper gives an overview of newly designed tram track structures designated for use on Zagreb tram network and their performance in terms of noise and vibration mitigation. Research has been conducted on a 150 m long test section consisted of three tram track types: standard tram track structure commonly used on tram lines in Zagreb, optimized tram structure for better noise and vibration mitigation and a slab track with double sleepers embedded in a concrete slab, which presents an entirely new approach of tram track construction in Zagreb. Track has been instrumented with acceleration sensors, strain gauges and revision shafts for inspection. Relative deformations give an insight into track structure dynamic load distribution through the exploitation period. Further the paper describes vibro-acoustic measurements conducted at the test site. To evaluate the track performance from the vibro-acoustical standpoint, detailed analysis of track decay rate has been analysed. Opposed to measurement technique using impact hammer for track decay rate measurements, newly developed measuring technique using vehicle pass by vibrations as a source of excitation has been proposed and analysed. Paper gives overview of the method, it’s benefits compared to standard method of track decay rate measurements and method evaluation based on noise measurements of the vehicle pass by.

    2010-08-01

    To establish the incidence and pattern of injuries in patients presenting to hospital with tram-related injuries. Data on tram-related injury pertaining to 2001-2008 calendar years were extracted from three datasets: the population-based Victorian State Trauma Registry for major trauma cases, the Victorian Emergency Minimum Dataset for ED presentations and the National Coroners' Information System for deaths. Incidence rates adjusted for the population of Melbourne, and trends in the incidence of tram-related ED presentations and major trauma cases, were analysed and presented as incidence rate ratios (IRR). There were 1769 patients who presented to ED after trauma related to trams in Melbourne during the study period. Of these, 107 patients had injuries classified as major trauma. There was a significant increase in the rate of ED presentations (IRR 1.03, P = 0.010) with falls (46%) the most commonly reported mechanism. Most falls occurred inside the trams. There was also a significant increase in the incidence rates of major trauma cases (IRR 1.12, P = 0.006) with pedestrians accounting for most major trauma cases. Most cases of trauma related to trams have minor injuries and are discharged following ED management. Primary prevention of falls in trams and the separation of pedestrians from trams are key areas requiring immediate improvement. In the face of increasing trauma associated with trams, continuing safety surveillance and targeted public safety messages are important to sustain trams as safe and effective mode of transport.

    2015-01-01

    Geneva is variously known as the city of peace, the world’s smallest metropolis and a place where great ideas have taken form. It has been the home to philosophers such as Rousseau and Voltaire. It was the centre of the Calvinist reformation and birthplace of the Red Cross.   I hardly need to tell you that it is also a city of great international collaboration in science. Little wonder, then, that over the years, Geneva has developed into the world’s capital of internationalism in the broadest sense of the word. Yet while we all know of the existence of modern day International Geneva, how many of us really know what it does? Here at CERN, we’re about to find out. Next week sees the first in a series of talks at the Laboratory from the heads of some of the institutions that make up International Geneva.

It was somewhat narrower in scope than the previous conferences held in 1935 and 1958, the emphasis being on nuclear power and closely related topics; the conference showed that recent progress in this field had provided more than ample material for a major international gathering. All three conferences have been organized by the United Nations, but on this occasion responsibility for the scientific aspects was delegated to IAEA. The UN Scientific Advisory Committee provided advice and guidance on the scientific side. Under the presidency of Professor V. S. Emelyanov (USSR) the conference sat from 31 August to 9 September, to deal with a programme divided into eight general sessions and 36 technical sessions, for which a total of nearly 750 papers were presented. About 1800 delegates and advisers, representing 75 countries as well as UN agencies, attended; in addition there were some 2000 observers. The central theme of the conference was experience in the construction and operation of power reactors and recent advances in power technology, together with forecasts of future developments. Nuclear fuels and reactor materials, health and safety, waste disposal, and economics of nuclear power figured largely. Technical sessions were devoted to such subjects as the technical and economic aspects of the power reactor systems currently in operation or being built, and the main lines of development towards more advanced systems and development of the fast breeder.

    2015-06-01

    Full Text Available This paper uses automatic vehicle location (AVL records to investigate the effect of weather conditions on the travel time reliability of on-road rail transit, through a case study of the Melbourne streetcar (tram network. The datasets available were an extensive historical AVL dataset as well as weather observations. The sample size used in the analysis included all trips made over a period of five years (2006–2010 inclusive, during the morning peak (7 am–9 am for fifteen randomly selected radial tram routes, all traveling to the Melbourne CBD. Ordinary least square (OLS regression analysis was conducted to create a linear model, with tram travel time being the dependent variable. An alternative formulation of the model is also compared. Travel time was regressed on various weather effects including precipitation, air temperature, sea level pressure and wind speed; as well as indicator variables for weekends, public holidays and route numbers to investigate a correlation between weather condition and the on-time performance of the trams. The results indicate that only precipitation and air temperature are significant in their effect on tram travel time. The model demonstrates that on average, an additional millimeter of precipitation during the peak period adversely affects the average travel time during that period by approximately 8 s, that is, rainfall tends to increase the travel time. The effect of air temperature is less intuitive, with the model indicating that trams adhere more closely to schedule when the temperature is different in absolute terms to the mean operating conditions (taken as 15 °C.

    Geneva has a long history of hosting international organizations, which is part of the reason why CERN is here, and it makes the canton an ideal place to forge links between such organizations. Over recent weeks, CERN has signed agreements with the ITU, WIPO and the WMO. At first sight, there may not seem to be much common ground between CERN and, say, the World Meteorological Organization, but scratch the surface, and you’ll soon find a common thread. All of these organizations have a vocation to stimulate technological innovation, and together we’re stronger.   Let’s start with ITU, the International Telecommunications Union. There, the synergies are evident. When ITU organized the World Summit on the Information Society in 2003, CERN provided a significant side event examining the Role of Science in the Information Society. The current agreement builds on that, allowing our two organizations to work together on important societal issues such as the extension of b...

    Objectives: To report findings in bone scans for breast cancer patients with mastectomy and breast reconstruction with transverse rectus abdominis myocutaneous flap (TRAM). Material and Methods: Inclusion criteria were: confirmed breast cancer, mastectomy, breast reconstruction with TRAM flap and bone scan performed after TRAM. Exclusion criteria were: Absence of bone scan image, breast reconstruction by other approaches. Results: Absence of uptake in TRAM flap in six patients, diminished uptake in skin near TRAM, with peripheral increased uptake in three and increased uptake in TRAM flap, in a patient with cancer recurrence, confirmed by biopsy. Conclusions: Bone scans in breast cancer patients with mastectomy and TRAM flap can have different imaging presentations, procedure details diminish reporting errors. TRAM flap may present fat necrosis areas, which should be differentiated from recurrence in bone scans. Additional imaging and biopsy will be needed to diagnose this finding. (authors).

Fifty years earlier, at the Geneva Conference for the Control of the International Trade in Arms, Munitions and Implements of War, the United States had played a key role in drafting and reaching agreement on the Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or Other Gases and of Bacteriological Methods of Warfare. The protocol, signed by thirty nations, including the United States, on June 17, 1925, prohibits the use in war of asphyxiating, poisonous or other gases, and of all analogous liquids, materials or devices as well as the use of bacteriological methods of warfare

    Full Text Available The paper deals with the problems of routing control algorithms of new conception of tram vehicle bogie. The main goal of these research activities is wear reduction of rail wheels and tracks, wear reduction of traction energy losses and increasing of running comfort. The testing experimental tram vehicle with special bogie construction powered by traction battery is utilized for these purposes. This vehicle has a rotary bogie with independent rotating wheels driven by permanent magnets synchronous motors and a solid axle. The wheel forces in bogie are measured by large amounts of the various sensors placed on the testing experimental tram vehicle. Nowadays the designed control algorithms are implemented to the vehicle superset control system. The traction requirements and track characteristics have an effect to these control algorithms. This control including sophisticated routing brings other improvements which is verified and corrected according to individual traction and driving characteristics, and opens new possibilities.

  14. [Pedicled versus free TRAM flap for breast reconstruction].

    1999-03-01

    In breast reconstruction, the free TRAM-flap offers many advantages over the pedicled TRAM-flap. Due to its superior perfusion, the free flap rarely develops necrosis. Shaping of the flap is easier due to the lack of the thick muscle pedicle. Because the rectus muscle is spared, there is minimal donor site morbidity. However, the necessary microvascular anastomoses reduced the acceptance of the free TRAM-flap. During a 13-months period, 51 breast reconstructions were performed in 41 patients, 31 unilateral and ten bilateral. 45 flaps served for delayed reconstruction and six flaps for immediate reconstruction. The operations were performed by two teams working simultaneously. The average operating time was 3.9 hours for unilateral and 6.9 hours for bilateral delayed reconstruction. For immediate reconstruction, 6.2 and 6.3 hours were required for uni- and bilateral procedures, respectively. In 38 flaps, the thoracodorsal vessels served as recipient vessels; 13 flaps were anastomosed to the internal mammary artery and vein. Postoperative complications were observed in 13 patients. Three vessel anastomoses had to be revised. In one flap, a partial necrosis occurred; in two flaps hematoma evacuation was necessary. Two patients suffered from fat necroses at the abdomen and one umbilicus was lost. Skin irritations and seromas at the abdomen occurred in five patients. Pulmonary embolism was diagnosed in one patient three weeks postoperatively. Abdominal hernias or bulging in the epigastric area were not observed up to 15 months after reconstruction. These results reveal a low complication rate for breast reconstruction with the free TRAM-flap. The advantages of this technique as compared to the pedicled technique are discussed.

    2016-01-01

    Streetcars/tram systems are growing worldwide, and many are given priority to increase speed and reliability performance in mixed traffic conditions. Research related to the road safety impact of tram priority is limited. This study explores the road safety impacts of tram priority measures including lane and intersection/signal priority measures. A before-after crash study was conducted using the empirical Bayes (EB) method to provide more accurate crash impact estimates by accounting for wider crash trends and regression to the mean effects. Before-after crash data for 29 intersections with tram signal priority and 23 arterials with tram lane priority in Melbourne, Australia, were analyzed to evaluate the road safety impact of tram priority. The EB before-after analysis results indicated a statistically significant adjusted crash reduction rate of 16.4% after implementation of tram priority measures. Signal priority measures were found to reduce crashes by 13.9% and lane priority by 19.4%. A disaggregate level simple before-after analysis indicated reductions in total and serious crashes as well as vehicle-, pedestrian-, and motorcycle-involved crashes. In addition, reductions in on-path crashes, pedestrian-involved crashes, and collisions among vehicles moving in the same and opposite directions and all other specific crash types were found after tram priority implementation. Results suggest that streetcar/tram priority measures result in safety benefits for all road users, including vehicles, pedestrians, and cyclists. Policy implications and areas for future research are discussed.

  17. Conserved TRAM Domain Functions as an Archaeal Cold Shock Protein via RNA Chaperone Activity

    2017-08-01

    Full Text Available Cold shock proteins (Csps enable organisms to acclimate to and survive in cold environments and the bacterial CspA family exerts the cold protection via its RNA chaperone activity. However, most Archaea do not contain orthologs to the bacterial csp. TRAM, a conserved domain among RNA modification proteins ubiquitously distributed in organisms, occurs as an individual protein in most archaeal phyla and has a structural similarity to Csp proteins, yet its biological functions remain unknown. Through physiological and biochemical studies on four TRAM proteins from a cold adaptive archaeon Methanolobus psychrophilus R15, this work demonstrated that TRAM is an archaeal Csp and exhibits RNA chaperone activity. Three TRAM encoding genes (Mpsy_0643, Mpsy_3043, and Mpsy_3066 exhibited remarkable cold-shock induced transcription and were preferentially translated at lower temperature (18°C, while the fourth (Mpsy_2002 was constitutively expressed. They were all able to complement the cspABGE mutant of Escherichia coli BX04 that does not grow in cold temperatures and showed transcriptional antitermination. TRAM3066 (gene product of Mpsy_3066 and TRAM2002 (gene product of Mpsy_2002 displayed sequence-non-specific RNA but not DNA binding activity, and TRAM3066 assisted RNases in degradation of structured RNA, thus validating the RNA chaperone activity of TRAMs. Given the chaperone activity, TRAM is predicted to function beyond a Csp.

    Over recent years, CERN has been tightening its links with fellow organisations in Geneva’s vibrant international community.   This has brought home to me just how important it is for such a diverse group of international organisations to be located in the same place as CERN. In some cases, the relevance to CERN’s missions is clear, and for a few, the links go way back. When the International Telecommunication Union organised the World Summit on the Information Society in 2003, for example, it was natural for CERN to get involved with a side event on the Role of Science in the Information Society. And similarly, it is clear that we have a strong stake in the work of organisations such as the World Intellectual Property Organization, and that our infrastructure makes the partnership with UNOSAT a natural fit. But what of the other international organisations, around 30 of them, or the 250 NGOs that are based here? The acting head of the United Nations Office at Geneva, Mic...

  6. Structural safety of trams in case of misguidance in a switch

    Schindler, Christian; Schwickert, Martin; Simonis, Andreas

    2010-08-01

    Tram vehicles mainly operate on street tracks where sometimes misguidance in switches occurs due to unfavourable conditions. Generally, in this situation, the first running gear of the vehicle follows the bend track while the next running gears continue straight ahead. This leads to a constraint that can only be solved if the vehicle's articulation is damaged or the wheel derails. The last-mentioned situation is less critical in terms of safety and costs. Five different tram types, one of them high floor, the rest low floor, were examined analytically. Numerical simulation was used to determine which wheel would be the first to derail and what level of force is needed in the articulation area between two carbodies to make a tram derail. It was shown that with pure analytical simulation, only an idea of which tram type behaves better or worse in such a situation can be gained, while a three-dimensional computational simulation gives more realistic values for the forces that arise. Three of the four low-floor tram types need much higher articulation forces to make a wheel derail in a switch misguidance situation. One particular three-car type with two single-axle running gears underneath the centre car must be designed to withstand nearly three times higher articulation forces than a conventional high-floor articulated tram. Tram designers must be aware of that and should design the carbody accordingly.

    The investigation of thermal-hydraulic phenomena related to reactor transients with accident management measures is the goal of the TRansient and accident Management (TRAM) experimental programme being carried out at the Upper Plenum Test Facility (UPTF) at Mannheim (Germany). These experimental investigations and test analyses are funded by the German Federal Minister for Research and Technology (BMFT). The UPTF simulates these phenomena in a 1:1 such relative to the dimension of a PWR. Condensation of steam during Emergency Core Cooling (ECC) water injection from accumulators into the primary system is one of the phenomena studied within the accumulators into the primary system is one of the phenomena studied within the TRAM programme. This phenomenon partly controls the efficiency of accumulator injection if the high pressure safety systems fail. Beside this, the condensation within the nitrogen inside the accumulator for a certain period controls the pressure development inside the accumulator. Thus, both condensation phenomena determine the ECC flow rate delivered to the primary system. Concerning the condensation inside the primary system, this is also of safety relevance in the case of Pressurized Thermal Shock (PTS) during cold leg injection.

  8. The TIR-domain containing adaptor TRAM is required for TLR7 mediated RANTES production.

    Directory of Open Access Journals (Sweden)

    Enda Shevlin

    Full Text Available Toll-like receptor 7 (TLR7 plays a vital role in the immune response to ssRNA viruses such as human rhinovirus (HRV and Influenza, against which there are currently no treatments or vaccines with long term efficacy available. Clearly, a more comprehensive understanding of the TLR7 signaling axis will contribute to its molecular targeting. TRIF related adaptor molecule (TRAM plays a vital role in TLR4 signaling by recruiting TRIF to TLR4, followed by endosomal trafficking of the complex and initiation of IRF3 dependent type I interferon production as well as NF-κB dependent pro-inflammatory cytokine production. Towards understanding the molecular mechanisms that regulate TLR7 functionality, we found that TRAM(-/- murine macrophages exhibited a transcriptional and translational impairment in TLR7 mediated RANTES, but not TNFα, production. Suppression of TRAM expression in human macrophages also resulted in an impairment in TLR7 mediated CCL5 and IFN-β, but not TNFα, gene induction. Furthermore, suppression of endogenous human TRAM expression in human macrophages significantly impaired RV16 induced CCL5 and IFNβ, but not TNFα gene induction. Additionally, TRAM-G2A dose-dependently inhibited TLR7 mediated activation of CCL5, IFNβ and IFNα reporter genes. TLR7-mediated phosphorylation and nuclear translocation of IRF3 was impaired in TRAM(-/- cells. Finally, co-immunoprecipitation studies indicated that TRAM physically interacts with MyD88 upon TLR7 stimulation, but not under basal conditions. Our results clearly demonstrate that TRAM plays a, hitherto unappreciated, role in TLR7 signaling through a novel signaling axis containing, but not limited to, MyD88, TRAM and IRF3 towards the activation of anti-viral immunity.

    conducted in the Bullfrog and Tram intervals. Longitudinal dispersivity values in the Bullfrog and Tram Tuffs ranged from 1.83 to 2.6 meters, flow-porosity values from 0.072 to 0.099, and matrix-porosity values from 0.088 to 0.19. The flow-porosity values indicate that the pathways between boreholes UE-25 c#2 and UE-25 c#3 in the Bullfrog and Tram intervals are not connected well. Tracer testing in the Prow Pass interval indicates different transport characteristics than those obtained in the Bullfrog and Tram intervals. In the Prow Pass Tuff, longitudinal dispersivity was 0.27 meter, flow porosity was 4.5 ? 10?4, and matrix porosity was 0.01. This indicates that the flow network in the Prow Pass is dominated by interconnected fractures, whereas in the Bullfrog and Tram, the flow network is dominated by discontinuous fractures with connecting segments of matrix.

    Bombardier and transport operator Rhein-Neckar-Verkehr GmbH (RMV) are equipping a fleet of trams with energy storage systems - a first. Compared with modern regenerative-braking trams, the new energy storage technology yields energy savings of 25%. The energy storage system will also enable the introduction of a new tram line in the Neuenheimer Feld district of Heidelberg, which up to now has been rejected by the adjoining university departments. When powered by the energy storage system, i.e. without power input from the overhead line, the trams are likely to produce much less radiation of magnetic fields, which has been the main reason why the university departments at Neuenheimer Feld have opposed the plan. The Mitrac Energy Saver system has already been field-tested in daily revenue service in Mannheim. (orig.)

    2016-07-01

    Safety is a key concern in the design, operation and development of light rail systems including trams or streetcars as they impose crash risks on road users in terms of crash frequency and severity. The aim of this study is to identify key traffic, transit and route factors that influence tram-involved crash frequencies along tram route sections in Melbourne. A random effects negative binomial (RENB) regression model was developed to analyze crash frequency data obtained from Yarra Trams, the tram operator in Melbourne. The RENB modelling approach can account for spatial and temporal variations within observation groups in panel count data structures by assuming that group specific effects are randomly distributed across locations. The results identify many significant factors effecting tram-involved crash frequency including tram service frequency (2.71), tram stop spacing (-0.42), tram route section length (0.31), tram signal priority (-0.25), general traffic volume (0.18), tram lane priority (-0.15) and ratio of platform tram stops (-0.09). Findings provide useful insights on route section level tram-involved crashes in an urban tram or streetcar operating environment. The method described represents a useful planning tool for transit agencies hoping to improve safety performance. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2015-12-01

    Transverse rectus abdominis musculocutaneous (TRAM) flap is the most common procedure performed for breast reconstruction after mastectomy for breast cancer. Obesity is a relative contraindication, and complex modifications have been proposed in the pedicled technique for obese patients. We studied ischemic complications in our patients to investigate the effect of body weight on the outcome of TRAM flap breast reconstruction. Pertinent data from medical records of patients receiving a TRAM flap surgery from 1986 to 2011 were extracted. Patients were divided into three groups based on the body mass index (BMI): normal (obese (>30 kg/m(2)). Flap necrosis is defined as any visible nonviable tissue in the reconstructed breast. It was observed that 117 patients had received TRAM flap reconstruction. Fifty-eight patients were excluded. Of the remaining 59 cases, 24 had normal BMI, 21 were overweight, and 14 were obese. No patient was found to develop flap necrosis. Outcome of TRAM flap breast reconstruction in obese patients is similar to nonobese patients. No major necrosis in need of reoperation was identified in the studied obese patients. It was concluded that categorizing obesity as a relative contraindication to TRAM flap breast reconstruction should be revisited based on larger cohort studies.

    Highlights: • The hybridization of the fuel cell with the energy storage systems is realized for the tram. • A protype tram is tested based on an operation mode switching method. • An equivalent consumption minimization strategy is proposed and verified for optimization. - Abstract: This paper describes a hybrid tram powered by a Proton Exchange Membrane (PEM) fuel cell (FC) stack supported by an energy storage system (ESS) composed of a Li-ion battery (LB) pack and an ultra-capacitor (UC) pack. This configuration allows the tram to operate without grid connection. The hybrid tram with its full load is tested in the CRRC Qingdao Sifang Co.; Ltd. It firstly works on the operation mode switching method (OPMS) without energy regenerative and proper power management. Therefore, an equivalent consumption minimization strategy (ECMS) aimed at minimizing the hydrogen consumption is proposed to improve the characteristics of the tram. The results show that the proposed control system enhances drivability and economy, and is effective for application to this hybrid system.

The FRT was designed to have a transportation capacity of 2500 to 5000 persons per direction per hour, and a train set of 2 or 3 cars. Each vehicle was provided with a precise docking system in order to reduce boarding times. Vehicles were also equipped with low floors with easy access for handicapped and elderly passengers. The FRT system was primarily powered by fuel cells, had zero emissions, and were constructed of composite materials using a bimodal structure. The system was comprised of a hybrid power system with a combined compressed natural gas (CNG) and battery system alongside the fuel cell system. The paper included the results of a modelling study which examined the fuel cell at various energy production capacities. Details of the system's guidance system were also provided. Results of the modelling study showed that the FRT was capable of achieving the speed of a subway on roads and exclusive tracks through the use of a signaling system. 2 tabs., 8 figs.

  3. Tuning Geneva+Pythia 8 Using Professor 2

    Gellersen, Leif Erik

    2016-01-01

    We study the tuning of the Geneva Monte Carlo framework to LHC data. Geneva improves the predictions for Drell-Yan production by including NNLO QCD corrections and extending the resummation accuracy to NNLL$'$ for 0-jettiness and NLL for 1-jettiness. The partonic results provided by Geneva are interfaced to Pythia 8 for showering including its multiple parton interaction (MPI) model. This allows us to obtain sensible predictions for Underlying Event (UE) sensitive observables too. Retuning Geneva + Pythia 8 to LHC data with the Professor 2 package shows an improved agreement for both UE sensitive and more inclusive observables.

  4. Technical risk audit method (tram): development and application to the auditing of major hazard sites

    Maddison, T.; Kirk, P.; Stansfield, R.

    1998-01-01

    The Technical Risk Audit Method (TRAM) has been developed by the UK Health and Safety Executive (UK HSE) as a risk-based auditing and inspection tool for application to Major Hazard process plant covered by the Seveso-I/Seveso-II directives. The objective of TRAM is to provide a framework in which plant inspection or audit can be undertaken and results collated. TRAM comprises a paper audit procedure and a software tool which is used to analyse the results. TRAM includes a semi-quantitative risk model, which may be used to rank risks both within and between similar facilities, using qualitative data collected during the inspection. The results of this qualitative analysis may be used to identify where inspector resources would be best deployed. To date, TRAM has been applied to a number of LPG storage and processing facilities in the UK, and the lessons learnt are being used to develop a robust version suitable for use by inspectors. The methodology will be made consistent with the risk model included in IEC 61508 'Functional safety of electrical/electronic/programmable electronic safety-related systems' to permit its application to a wide range of process plant and other hazardous facilities.

    2018-02-01

    This paper proposes an optimal control strategy based on the two-dimension dynamic programming (2DDP) algorithm targeting at minimizing operation energy consumption for a fuel-cell tram. The energy consumption model with the tram dynamics is firstly deduced. Optimal control problem are analyzed and the 2DDP strategy is applied to solve the problem. The optimal tram speed profiles are obtained for each interstation which consist of three stages: accelerate to the set speed with the maximum traction power, dynamically adjust to maintain a uniform speed and decelerate to zero speed with the maximum braking power at a suitable timing. The optimal control curves of all the interstations are connected with the parking time to form the optimal control method of the whole line. The optimized speed profiles are also simplified for drivers to follow.

    2010-04-01

    To obtain pleasing symmetry in breast reconstruction with transverse rectus abdominis myocutaneous (TRAM) free flap, a large amount of abdominal flap is elevated and remnant tissue is trimmed in most cases. However, elevation of abundant abdominal flap can cause excessive tension in donor site closure and increase the possibility of hypertrophic scarring especially in lean patients. The TRAM flap was divided into 4 zones in routine manner; the depth and dimension of the 4 zones were obtained using ultrasound and AutoCAD (Autodesk Inc., San Rafael, CA), respectively. The acquired numbers were then multiplied to obtain an estimate of volume of each zone and the each zone volume was added. To confirm the relation between the estimated volume and the actual volume, authors compared intraoperative actual TRAM flap volumes with preoperative estimated volumes in 30 consecutive TRAM free flap breast reconstructions. The estimated volumes and the actual elevated volumes of flap were found to be correlated by regression analysis (r = 0.9258, P Autodesk Inc.) allow the authors to attain the precise volume desired for elevation. This method provides advantages in terms of minimal flap trimming, easier closure of donor sites, reduced scar widening and symmetry, especially in lean patients.

    2016-06-01

    Full Text Available Transport has always had an important role in the lifestyle of population and development of economy, but the public transport performs mainly the social function – it works for the benefit of the society. Development and quality of services must be provided also for the public transport companies, however, we meet different problems related to infrastructure and traffic for this to happen. To successfully manage and develop a public transport company, it is essential to change the thinking of people in favour of the public transport, not for the personal transport. It is necessary to ensure the sustainability as the main value, which means selection of the right public transport system. The authors relied on the experience of formation of a unified transport system in the world and Latvia’s largest cities’ strategic vision for public transport development. Taking into account the fact that Liepaja is one the three cities in Latvia where the public transport service is provided by a tram, an empiric research was made. Its aim was to clarify the opinion of the inhabitants of Liepaja, regarding the services provided by Liepaja trams, regarding the possible improvements and necessity for development. 200 inhabitants of Liepaja were questioned within the framework of the research. The results of the research revealed that although the tram provides daily the inhabitants of Liepaja with the movement possibilities, unfortunately inhabitants are not ready yet to replace their personal transport with the public transport – tram to settle their daily problems. The results of the research allowed to conclude that future development possibilities and perspectives of the tram in Liepaja City can be related mainly with the creation of a new route, purchase of new carriages and unified public transport system in Liepaja City.

    The First International Conference on the Peaceful Uses of Atomic Energy had its origin in President Eisenhower's initiative of the early nineteen-fifties, when he proposed a concerted international effort to divert the power of the atom from warlike purposes into the service of peace. To the United Nations General Assembly in December 1953, he pledged the determination of the United States 'to help solve the fearful atomic dilemma - to devote its entire heart and mind to finding the way by which the miraculous inventiveness of man shall not be dedicated to his death, but consecrated to his life'. The UN General Assembly in plenary session, in December 1954, unanimously and enthusiastically adopted a resolution which provided for the establishment of an International Atomic Energy Agency, and for the holding of an international technical conference of governments under the auspices of the United Nations. To prepare the way, an Advisory Committee was set up, consisting of representatives of Brazil, Canada, France, India, USSR, United Kingdom and USA. The result was the largest meeting that had been convened under the auspices of the United Nations; it was held from 8 to 25 August 1955 in the Palais des Nations, Geneva, where the necessary facilities were available for such a large multilingual conference. Thirty-eight governments submitted 1067 papers and 1428 participants attended. The conference was wide in scope, embracing all major aspects of the peaceful applications of atomic energy.

    2010-01-01

    Occupational eye trauma causes injuries with often serious socioprofessional, medical-legal, and economic consequences, not only for workers themselves, but also for employers. In spite of today's legislation and the efforts to encourage prevention, the frequency of occupational ocular accidents remains relatively high despite how easy it is to protect the eyes. In this study, the reasons that these accidents persist despite the progress made in preventive measures was investigated. From January to July 2005, we analyzed the parameters related to 175 occupational eye injuries. All patients agreed to take part in this study, which was carried out in the emergency unit of the Ophthalmology Clinic at Geneva University Hospital. Additional data was collected in companies. Construction workers were the most exposed (41.1%). The activity with the greatest risk was grinding (19.4%). The most affected structure of the eye was the cornea (84%), 72.6% patients were not equipped with ocular protection at the time of the accident, and 17.4% wore poorly adapted eye protection. This can be explained by negligence, lack of awareness, etc. Overall, workers, employers, and the legislation in force are all responsible. Our results are comparable with those found in the literature, with certain particularities because heavy industry was underrepresented in our sample. Analysis of the law on the prevention of occupational accidents and diseases shows that the worker is not sufficiently aware of his responsibilities. To our knowledge, the legal aspects treated herein have not been studied. As done in certain studies, we emphasize the importance of preventive ophthalmologic examinations as well as improvement of both working conditions and worker awareness in the workplace. Primary prevention must be reinforced. Information campaigns within the workplace aimed at workers and revision of the laws on occupational safety are some of the recommendations that are proposed to control

    2018-01-01

    The pedicled transverse rectus abdominis myocutaneous (TRAM) flap procedure is still widely used for breast reconstruction. The repair of the flap harvest site in the transverse rectus abdominis muscle and sheath is often assisted by the use of prosthetic meshes. This decreases the risk of abdominal wall weakness and herniation but, being a foreign body, it also carries the risk of infection. In this report, we describe the case of a 63-year-old patient who, whilst receiving chemotherapy for metastatic breast cancer, presented with an infected polytetrafluoroethylene mesh 15 years after pedicled TRAM flap immediate breast reconstruction. This necessitated mesh removal to treat the infection. Following a thorough review of the English literature, this is the longest recorded presentation of an abdominal prosthetic mesh infection. The mechanism and aetiology of such a late complication are discussed.

    Addiction care is mostly provided by general practitioners (GPs) but the extent of their involvement is variable. Is this related to different training or practice contexts or to awareness campaigns? To study GPs' views and behaviours in relation to addiction patients in different practice and training contexts and different levels of exposure to awareness campaigns. Cross-sectional postal survey involving 526 GPs from the canton of Geneva, Switzerland, sensitized by specific addiction care campaigns, compared to 628 GPs from two rural Departments of Poitou-Charentes, France, not exposed to this type of awareness campaign. The response rate was 46% in Switzerland and 41% in France. The 243 responding GPs in Geneva saw as many patients with tobacco, alcohol, cannabis or opiate addiction as the 256 GPs in Poitou-Charentes. They shared similar views concerning their roles in relation to these addictions. Compared to Swiss GPs, a significantly higher number of French GPs provided first-line care for tobacco addiction. In both countries, care for addiction to other substances was mostly provided in collaboration with a specialist (>75% of cases). GPs in Geneva attributed greater importance to screening and recording of substance use. They were also more involved in training and in providing brief advice and expressed interest in the network. Awareness campaigns in Geneva could explain these differences. Sensitization of GPs to these issues may contribute to modifying certain professional attitudes, regardless of the context.

    Purpose: Radiotherapy (RT) has an important role in breast cancer treatment after modified radical mastectomy. Many of these patients also undergo breast reconstruction. We reviewed our institutions' experience to determine the outcome of patients treated with breast reconstruction and RT. Methods and Materials: Between 1981 and 1999, 48 breast cancer patients underwent modified radical mastectomy, breast reconstruction, and ipsilateral breast RT during their treatment course. Reconstruction either preceded or followed RT. Autologous reconstruction with a transverse rectus abdominus myocutaneous (TRAM) flap was performed in 30 patients, and 18 underwent expander and implant (E/I) reconstruction. The primary endpoint was the quality of the reconstructed, irradiated breast, as measured by analyzing the actuarial incidence of complications. The cosmetic outcome was also assessed by multidisciplinary review of the follow-up visits. Results: The median follow-up from reconstruction was 32 months. The actuarial 2-year complication rate was 53% for patients receiving E/I vs. 12% for those receiving TRAM reconstruction (p<0.01). No other patient or treatment-related factors had a significant impact on complications. The cosmetic outcome was also significantly better in the TRAM subgroup than in the E/I subgroup. Conclusion: The tolerance and cosmetic outcome of breast reconstruction for breast cancer patients in irradiated sites depends significantly on the type of reconstruction used

The organisers of 'Ge.02' have chosen to experiment with the links between the communities of different nationalities living in Geneva, giving the event the subtitle 'De quoi GE me mêle'. Some thirty themes for Geneva have been identified, including relations between the various religions, the position of the elderly in a changing society and science in action at CERN. Each of these themes has been explored by a group of people of different cultural and social backgrounds, nicknamed the 'Ge.02 communities', which were formed over two years ago.

  13. TRAM is involved in IL-18 signaling and functions as a sorting adaptor for MyD88.

    Directory of Open Access Journals (Sweden)

    Hidenori Ohnishi

    Full Text Available MyD88, a Toll/interleukin-1 receptor homology (TIR domain-containing adaptor protein, mediates signals from the Toll-like receptors (TLR or IL-1/IL-18 receptors to downstream kinases. In MyD88-dependent TLR4 signaling, the function of MyD88 is enhanced by another TIR domain-containing adaptor, Mal/TIRAP, which brings MyD88 to the plasma membrane and promotes its interaction with the cytosolic region of TLR4. Hence, Mal is recognized as the "sorting adaptor" for MyD88. In this study, a direct interaction between MyD88-TIR and another membrane-sorting adaptor, TRAM/TICAM-2, was demonstrated in vitro. Cell-based assays including RNA interference experiments and TRAM deficient mice revealed that the interplay between MyD88 and TRAM in cells is important in mediating IL-18 signal transduction. Live cell imaging further demonstrated the co-localized accumulation of MyD88 and TRAM in the membrane regions in HEK293 cells. These findings suggest that TRAM serves as the sorting adaptor for MyD88 in IL-18 signaling, which then facilitates the signal transduction. The binding sites for TRAM are located in the TIR domain of MyD88 and actually overlap with the binding sites for Mal. MyD88, the multifunctional signaling adaptor that works together with most of the TLR members and with the IL-1/IL-18 receptors, can interact with two distinct sorting adaptors, TRAM and Mal, in a conserved manner in a distinct context.

    To ensure good computer security, it is essential for us to keep in close contact and collaboration with a multitude of official and unofficial, national and international bodies, agencies, associations and organisations in order to discuss best practices, to learn about the most recent (and, at times, still unpublished) vulnerabilities, and to handle jointly any security incident. A network of peers - in particular a network of trusted peers - can provide important intelligence about new vulnerabilities or ongoing attacks much earlier than information published in the media. In this article, we would like to introduce a few of the official peers we usually deal with.*   Directly relevant for CERN are SWITCH, our partner for networking in Switzerland, and our contacts within the WLCG, i.e. the European Grid Infrastructure (EGI), and the U.S. Open Science Grid (OSG). All three are essential partners when discussing security implementations and resolving security incidents. SWITCH, in...

  17. Computation of wheel-rail contact force for non-mapping wheel-rail profile of Translohr tram

    Science.gov (United States)

    Ji, Yuanjin; Ren, Lihui; Zhou, Jinsong

    2017-09-01

    Translohr tram has steel wheels, in V-like arrangements, as guide wheels. These operate over the guide rails in inverted-V arrangements. However, the horizontal and vertical coordinates of the guide wheels and guide rails are not always mapped one-to-one. In this study, a simplified elastic method is proposed in order to calculate the contact points between the wheels and the rails. By transforming the coordinates, the non-mapping geometric relationship between wheel and rail is converted into a mapping relationship. Considering the Translohr tram's multi-point contact between the guide wheel and the guide rail, the elastic-contact hypothesis take into account the existence of contact patches between the bodies, and the location of the contact points is calculated using a simplified elastic method. In order to speed up the calculation, a multi-dimensional contact table is generated, enabling the use of simulation for Translohr tram running on curvatures with different radii.

    Full Text Available Transverse Rectus Abdominis Musculocutaneous (TRAM flap surgery is a prolonged and extensive procedure that requires multiple incisions. Recently, Transverse Abdominis Plane (TAP blocks have been found to be reliable method of providing regional analgesia for lower abdominal surgery and paravertebral block for pain management after breast surgery. Since the TRAM flap surgery involves both abdomen and thorax, the combination of these two blocks to manage post operative pain could be effective. This manuscript is one of the initial cases reporting of the use of these techniques in which triple catheters with ropivacaine infusion in breast reconstruction surgery were successfully used with reduced pain scores and opioid consumption.

    Access to detailed comparisons in air quality variations encountered when commuting through a city offers the urban traveller more informed choice on how to minimise personal exposure to inhalable pollutants. In this study we report on an experiment designed to compare atmospheric contaminants inhaled during bus, subway train, tram and walking journeys through the city of Barcelona. Average number concentrations of particles 10-300 nm in size, N, are lowest in the commute using subway trains (N5.0×10(4) cm(-3)), with extreme transient peaks at busy traffic crossings commonly exceeding 1.0×10(5) cm(-3) and accompanied by peaks in Black Carbon and CO. Subway particles are coarser (mode 90 nm) than in buses, trams or outdoors (1200 ppm in crowded buses and trains. There are also striking differences in inhalable particle chemistry depending on the route chosen, ranging from aluminosiliceous at roadsides and near pavement works, ferruginous with enhanced Mn, Co, Zn, Sr and Ba in the subway environment, and higher levels of Sb and Cu inside the bus. We graphically display such chemical variations using a ternary diagram to emphasise how "air quality" in the city involves a consideration of both physical and chemical parameters, and is not simply a question of measuring particle number or mass.

  1. Validation of CATHARE 3D code against UPTF TRAM C3 transients

    International Nuclear Information System (INIS)

    Glantz, Tony; Freitas, Roberto

    2007-01-01

    Within the nuclear reactor safety analysis, one of the events that could potentially lead to a recriticality accident in case of a Small Break LOCA (SBLOCA) in a pressurized water reactor (PWR) is a boron dilution scenario followed by a coolant mixing transient. Some UPTF experiments can be interpreted as generic boron dilution experiments. In fact, the UPTF experiments were originally designed to conduct separate effects studies focused on multi-dimensional thermal hydraulic phenomena. But, in the case of experimental program TRAM, some studies are realized on the boron mixing: tests C3. Some of these tests have been used for the validation and assessment of the 3D module of CATHARE code. Results are very satisfying; CATHARE 3D code is able to reproduce correctly the main features of the UPTF TRAM C3 tests, the temperature mixing in the cold leg, the formation of a strong stratification in the upper downcomer, the perfect mixing temperature in the lower downcomer and the strong stratification in the lower plenum. These results are also compared with the CFX-5 and TRIO-U codes results on these tests. (author)

    objectives and needs are similar. Concerning the architecture, the data model was developed according to the following themes: geology, hydrogeology, geophysics and geothermal energy. Each theme contains features that are characterized by a geometric shape (point, line or polygon), attribute tables and relations. The data model was designed to allow crossed requests between features though unique identifier (ID) attributes. PostgreSQL, an open-source database management system, was chosen to ensure a wide range of compatible GIS tools. This solution helps keeping the link between 2D and 3D geological data, especially through the cantonal platform (ge.ch/sitg/geologie3d) that stores and displays 3D models. To ensure the development of a geological IS, these aspects have been considered: 1) having a robust and scalable architecture 2) selecting adapted IT tools and 3) defining coherent data workflows. The future system should be able to answer queries to produce of maps, models and define protection zones, which assist an optimal management of the subsurface resources for the State of Geneva.

    2018-02-01

    Full Text Available A tram with on-board hybrid energy storage systems based on batteries and supercapacitors is a new option for the urban traffic system. This configuration enables the tram to operate in both catenary zones and catenary-free zones, and the storage of regenerative braking energy for later usage. This paper presents a multiple phases integrated optimization (MPIO method for the coordination of speed profiles and power split considering the signal control strategy. The objective is to minimize the equivalent total energy consumption of all the power sources, which includes both the energy from the traction substation and energy storage systems. The constraints contain running time, variable gradients and curves, speed limits, power balance and signal time at some intersections. The integrated optimization problem is formulated as a multiple phases model based on the characters of the signalized route. An integrated calculation framework, using hp-adaptive pseudospectral method, is proposed for the integrated optimization problem. The effectiveness of the method is verified under fixed time signal (FTS control strategy and tram priority signal (TPS control strategy. Illustrative results show that this method can be successfully applied for trams with hybrid energy storage systems to improve their energy efficiency.

  9. Safety impacts of platform tram stops on pedestrians in mixed traffic operation: A comparison group before-after crash study.

    2016-01-01

    Tram stops in mixed traffic environments present a variety of safety, accessibility and transport efficiency challenges. In Melbourne, Australia the hundred year-old electric tram system is progressively being modernized to improve passenger accessibility. Platform stops, incorporating raised platforms for level entry into low floor trams, are being retro-fitted system-wide to replace older design stops. The aim of this study was to investigate the safety impacts of platform stops over older design stops (i.e. Melbourne safety zone tram stops) on pedestrians in the context of mixed traffic tram operation in Melbourne, using an advanced before-after crash analysis approach, the comparison group (CG) method. The CG method evaluates safety impacts by taking into account the general trends in safety and the unobserved factors at treatment and comparison sites that can alter the outcomes of a simple before-after analysis. The results showed that pedestrian-involved all injury crashes reduced by 43% after platform stop installation. This paper also explores a concern that the conventional CG method might underestimate safety impacts as a result of large differences in passenger stop use between treatment and comparison sites, suggesting differences in crash risk exposure. To adjust for this, a modified analysis explored crash rates (crash counts per 10,000 stop passengers) for each site. The adjusted results suggested greater reductions in pedestrian-involved crashes after platform stop installation: an 81% reduction in pedestrian-involved all injury crashes and 86% reduction in pedestrian-involved FSI crashes, both are significant at the 95% level. Overall, the results suggest that platform stops have considerable safety benefits for pedestrians. Implications for policy and areas for future research are explored. Copyright © 2015 Elsevier Ltd.

    A 70 kW photovoltaic installation has been constructed on the roof of the new Building 6 of Geneva Palexpo, a compound that hosts various conferences, exhibitions and sporting or other events, counting almost 1.5 million visitors a year, including the International Car Show, which alone attracts more than 700,000 visitors each year. The purpose of this installation is the indirect supply of recharging terminals for electric vehicles. The solar installation and the electric vehicle recharging terminals support an information campaign on solar energy and 'sustainable' mobility. For this purpose various explanatory signs have been placed inside the Geneva Palexpo halls and a promotional stand for renewable energy and 'sustainable' transport was placed inside the International Car Show 2003. This stand had some success: more than 4,000 people took part in the competition organised on this occasion. (author)

    2011-02-01

    Full Text Available Abstract Background Several tools have been developed to perform global gene expression profile data analysis, to search for specific chromosomal regions whose features meet defined criteria as well as to study neighbouring gene expression. However, most of these tools are tailored for a specific use in a particular context (e.g. they are species-specific, or limited to a particular data format and they typically accept only gene lists as input. Results TRAM (Transcriptome Mapper is a new general tool that allows the simple generation and analysis of quantitative transcriptome maps, starting from any source listing gene expression values for a given gene set (e.g. expression microarrays, implemented as a relational database. It includes a parser able to assign univocal and updated gene symbols to gene identifiers from different data sources. Moreover, TRAM is able to perform intra-sample and inter-sample data normalization, including an original variant of quantile normalization (scaled quantile, useful to normalize data from platforms with highly different numbers of investigated genes. When in 'Map' mode, the software generates a quantitative representation of the transcriptome of a sample (or of a pool of samples and identifies if segments of defined lengths are over/under-expressed compared to the desired threshold. When in 'Cluster' mode, the software searches for a set of over/under-expressed consecutive genes. Statistical significance for all results is calculated with respect to genes localized on the same chromosome or to all genome genes. Transcriptome maps, showing differential expression between two sample groups, relative to two different biological conditions, may be easily generated. We present the results of a biological model test, based on a meta-analysis comparison between a sample pool of human CD34+ hematopoietic progenitor cells and a sample pool of megakaryocytic cells.

    Electricity is used substantially and sources of electric and magnetic fields are, unavoidably, everywhere. The transportation system is a source of these fields, to which a large proportion of the population is exposed. Hence, investigation of the effects of long-term exposure of the general public to low-frequency electromagnetic fields caused by the transportation system is critically important. In this study, measurements of electric and magnetic fields emitted from Australian trams, trains and hybrid cars were investigated. These measurements were carried out under different conditions, locations, and are summarised in this article. A few of the measured electric and magnetic field strengths were significantly lower than those found in prior studies. These results seem to be compatible with the evidence of the laboratory studies on the biological effects that are found in the literature, although they are far lower than international levels, such as those set up in the International Commission on Non-Ionising Radiation Protection guidelines.

We present the 5 years' experience with a 3-week residential Global Health and Human Rights Course developed at the University of Geneva and implemented with the support/participation of international organizations (IOs) and non-governmental organizations active in the health and human rights sector. Over the years, roughly 150 students from 43 nationalities, with many different educational backgrounds, attended the course. The male/female ratio was 1/5. The adopted educational approach was multifold and comprised lectures from academics and experts with field experience, group work, individual case studies, journal clubs, and site visits. Evaluation data show that site visits at IOs were highly appreciated as well as networking opportunities among students, with academics and experts with field experience. The variety of topics discussed was, at times, "too much"; yet, it allowed students to measure the extent of the challenges the field is facing. The adopted active learning approach facilitated the exchange of experiences among students and allowed them to get acquainted with different cultural sensitivities. The Global Health and Human Rights Summer-School of the University of Geneva allowed its participants, coming from all over the world, to identify challenges of the interlinked fields of health and human rights, reflect upon their underlying causes, and imagine possible solutions. Sharing our experience will hopefully help passionate educators around the world to develop similar programs.

    The detailed mineralogy of the Bullfrog and Tram Members of the Crater Flat Tuff from drill hole USW-G1 has been examined, primarily to characterize fully the amounts and types of clay minerals in the tuffs and the possible effects clay minerals have on rock properties. Results of bulk sample x-ray diffraction analyses agree closely with previous determinations, although slightly higher clay mineral contents were found in this study. X-ray diffraction analysis of fine fractions revealed that the clay minerals in the tuffs are sodium-saturated montmorillonite-beidellites with typical layer charges and no high-charge layers. These smectites are found in virtually all samples of the Bullfrog and Tram, and there is no correlation between the amounts of smectites and the amounts of zeolite, quartz, and feldspar. Smectites are present in both welded and nonwelded horizons and are scarce in some zones with slight-to-absent welding

    It has been proved that TRAM-Derived Decoy peptides have anti-inflammatory properties. In this study, we synthesized a TRAM-Derived decoy peptide (TM6), belongs to TRAM TIR domain, of which sequence is "N"-RQIKIWFQNRRMKWK, KENFLRDTWCNFQFY-"C" and evaluated the effects of TM6 on lipopolysaccharide-induced mastitis in mice. In vivo, LPS-induced mice mastitis model was established by injection of LPS through the duct of mammary gland. TM6 was injected 1h before or after LPS treatment. In vitro, primary mouse mammary epithelial cells were used to investigate the effects of TM6 on LPS-induced inflammatory responses. The results showed that TM6 inhibited LPS-induced mammary gland histopathologic changes, MPO activity, and TNF-α, IL-1β and IL-6 production in mice. In vitro, TM6 significantly inhibited LPS-induced TNF-α and IL-6 production, as well as NF-κB and MAPKs activation. In conclusion, this study demonstrated that TM6 had protective effects on LPS-mastitis and may be a promising therapeutic reagent for mastitis treatment. Copyright © 2015 Elsevier B.V.

    Full Text Available The Korea Railroad Research Institute (KRRI has developed a bimodal tram and advanced bus rapid transit (BRT system which is an optimized public transit system created by mixing the railway’s punctual operation and the bus’ easy and convenient access. The bimodal tram system provides mass-transportation service with an eco-friendly and human-centered approach. Natural disasters have been increasing worldwide in recent years, including floods, snow, and typhoons disasters. Flooding is the most frequent natural disaster in many countries and is increasingly a concern with climate change; it seriously affects people’s lives and productivity, causing considerable economic loss and significant damage. Enhanced conventional disaster management systems are needed to support comprehensive actions to secure safety and convenience. The objective of this study is to develop a prototype version of a Web GIS-based bimodal tram disaster management system (BTDMS using the Storm Water Management Model (SWMM 5.0 to enhance on-time operation and safety of the bimodal tram system. The BTDMS was tested at the bimodal tram test railroad by simulating probable maximum flood (PMF and snow melting for forecasting flooding and snow covered roads. This result could provide the basis for plans to protect against flooding disasters and snow covered roads in operating the bimodal tram system. The BTDMS will be used to assess and predict weather impacts on roadway conditions and operations and thus has the potential to influence economic growth. The methodology presented in this paper makes it possible to manage impacts of flooding and snowfall on urban transportation and enhance operation of the bimodal tram system. Such a methodology based on modeling could be created for most metropolitan areas in Korea and in many other countries.

  2. Influence of approaching tram on behaviour of pedestrians in signalised crosswalks in Poland.

    2013-06-01

    Research done in two Polish cities has uncovered an influence of an approaching tram on pedestrian behaviour. The measurements were done by counting pedestrians waiting for a green signal, crossing on red signal safely, or crossing on red signal taking a risk of being hit by a car, differentiating between pedestrians attempting to board a public transport vehicle and other pedestrians. It was expected, that pedestrian behaviour might be influenced by traffic control predictability, therefore two cities were chosen for the task: Wrocław with fixed time traffic control and Poznań with a majority of traffic responsive traffic signals. Data from the measurements was compared in order to find behaviour patterns - the comparison led to a conclusion, that an attempt to get on board of an incoming public transport vehicle can be a major cause for pedestrians to violate a red signal, including an increase of unsafe behaviour. These pedestrians may provoke other pedestrians to cross on a red signal. On the other hand if traffic control guarantees boarding the public transport vehicle, passengers-to-be may be even more obedient than other pedestrians. Copyright © 2013 Elsevier Ltd.

    Developing country mostly left behind in adopting e-Government system. Miss-interpretation is assuming e-Government only about the application of technology made fail implementation. It is a whole philosophy that explores a human-citizen centered aspect in organized societies. Further, successful information system determined by user acceptance. Therefore, the evaluation of the performance of e-Government is one of the basic objectives of current government reformation. The research focus is to identify and explore the extent of user acceptance toward e-Government system. The research methodology used in this research is survey based on a questionnaire with TRAM approach and distributed to 230 respondents as customers that had been using e-Government services provided by X institution. The result of the study showed that the personality traits of TR significantly influenced cognitive dimensions of TAM. Through empirical demonstrations indicated that the TRI was said to be antecedents to TAM. The optimism dimension had higher coefficient among others, exhibit the technology users convince that the new technology will improve their productivity, while discomfort had no impact since the users have no doubt or hesitate to use technology.

    In this study, the authors assessed SPACE code, which was developed by a consortium led by Korea Hydro and Nuclear Power Co., Ltd. (KHNP), now in licensing process and MARS-KS code for UPTF TRAM loop seal clearing experiment to evaluate the code predictability regarding loop seal clearing for supporting the regulatory review. The sensitivity of PT/CT sagging contact angle has been studied. The results of sagging contact angle could explain in different ways. In the case of wide sagging contact angle, the result is quite conservative in the aspect of containment as the heat is well-transferred to moderator. it causes the moderator to heat up. On the other hand, the narrow sagging contact angle results fuel heatup and give limiting condition for fuel integrity. As a result of estimation, a proper application of sagging contact angle is required to provide limiting condition for subsequent analysis. The results from the two codes were compared to the experimental data, but due to the lack of information on the uncertainties it is too early to conclude the both code's performance. However, from the obtained analysis results, some differences between MARS-KS and SPACE are initially observed. Especially, SPACE has larger oscillation in the calculated mass flow rate value than MARS-KS. This phenomenon was observed in comparison of SPACE and MARS-KS CCFL model as well.

    1992-10-01

    The separate effect UPTF TRAM Test A2 consisting of six runs was designed to investigate flow regimes in the hot leg of a pressurized water reactor under two-phase natural circulation conditions. In particular, the following phenomena were investigated: - Formation of different flow regimes, e.g. stratified and slug flow in the hot leg under different boundary conditions; -Correlation between flow regime and boundary conditions of the system (mass flows, water level etc.); - Mechanism of the transport of water into the steam generator. The test runs are divided into two groups: a) Test Runs 01a, 01b and 02b with steam injection through the core simulator: In these test runs the steam injection through the core simulator was increased stepwise. In each step the steam injection was kept constant for about 100 s in order to observe steady water distribution in the hot leg and SG-simulator of broken loop. b) Test Runs 03c, 04c and 04d with steam and water injection through the core simulator: These test runs were performed at a constant steam injection rate and the water injection rate was increased stepwise. In order to verify the consistency of scaling with the pressure, the test runs were carried out at different pressures as: a) Runs 01a and 01b at 15 bar, and Run 02b at 3 bar b) Runs 03c, 04c and 04d at 15, 3 and 5 bar respectively. A preliminary evaluation of the test is presented in the Quick Look Report. (orig.) [de

  8. A TRAM flap design refinement for use in delayed breast reconstruction.

    Patel, A J K

    2009-09-01

    Autologous breast reconstruction following mastectomy is commonly achieved using the free Transverse Rectus Abdominis Myocutaneous (TRAM) flap. Since its first description, refinements and modifications have resulted in improved operative techniques and more aesthetically pleasing reconstructions. Pre-operative flap design, however, is a relatively new concept that has not received much attention in the literature. Patients who undergo breast reconstruction may have large, ptotic contralateral breasts. In these patients there is a tendency to raise a large abdominal flap in an attempt to achieve symmetry, or simply a larger breast. This has the potential to lead to tight closure of the abdomen and the risk of subsequent wound problems. Reconstructions that are too small or have inadequate ptosis commit the patient to contralateral breast surgery to achieve symmetry. Pre-operatively designing the flap, using a template created from the opposite breast, can help achieve a good match, often reducing the need for contralateral breast surgery. Even when contralateral breast reduction surgery is planned in advance, many of these patients still require, and prefer, a large reconstruction in order to achieve a well-proportioned result. We present a design template that addresses these particular issues and in the senior author\\'s hands has proved to be a very effective technique. Our technique allows raising an abdominal flap of less vertical height than traditionally used (thus reducing the risk of tight abdominal closure) and incorporates an inverted V-shaped flap of skin from the inferior mastectomy skin flap into the reconstruction. This allows more flap tissue to be available to fill the upper poles of the reconstructed breast and at the same time produces good ptosis.

  9. Loss Model and Efficiency Analysis of Tram Auxiliary Converter Based on a SiC Device

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Currently, the auxiliary converter in the auxiliary power supply system of a modern tram adopts Si IGBT as its switching device and with the 1700 V/225 A SiC MOSFET module commercially available from Cree, an auxiliary converter using all SiC devices is now possible. A SiC auxiliary converter prototype is developed during this study. The author(s derive the loss calculation formula of the SiC auxiliary converter according to the system topology and principle and each part loss in this system can be calculated based on the device datasheet. Then, the static and dynamic characteristics of the SiC MOSFET module used in the system are tested, which aids in fully understanding the performance of the SiC devices and provides data support for the establishment of the PLECS loss simulation model. Additionally, according to the actual circuit parameters, the PLECS loss simulation model is set up. This simulation model can simulate the actual operating conditions of the auxiliary converter system and calculate the loss of each switching device. Finally, the loss of the SiC auxiliary converter prototype is measured and through comparison it is found that the loss calculation theory and PLECS loss simulation model is valuable. Furthermore, the thermal images of the system can prove the conclusion about loss distribution to some extent. Moreover, these two methods have the advantages of less variables and fast calculation for high power applications. The loss models may aid in optimizing the switching frequency and improving the efficiency of the system.

    Multiple preoperative, intraoperative and postoperative decisions can influence the outcome of microsurgical breast reconstruction. We have simplified the decision-making process by incorporating a number of algorithms into our microsurgical breast reconstruction practice and critically review our results in this study. Prospectively maintained databases for all microsurgical breast reconstructions performed by a single surgeon over a nine-year period were examined to determine: patient demographics; operative details including flap choice, donor and recipient vessel selection; and, details of intraoperative and early postoperative (406 Consecutive free flap microsurgical breast reconstructions (164 unilateral and 121 bilateral) were performed in 285 patients over the study period. Deep inferior epigastric artery perforator (DIEP) flaps (88%, n=359) were used most commonly followed by muscle-sparing transverse rectus abdominis musculocutaneous (MS-TRAM) flaps (11%, n=44), and fascial-sparing TRAM (FS-TRAM) flaps (0.7%, n=3). One-hundred-seventy-one (48%) DIEP flaps were based on a single perforator while 188 (52%) had multiple perforators. The internal mammary (IM) artery and vein were used as the recipient vessels for 99% (n=403) of flaps. A second venous anastomosis was required for 11.8 percent (n=48) of flaps. Partial flap failure occurred in nine (2.2%) flaps while total flap failure occurred in two flaps (0.5%). Minimum follow-up was three months. Incorporating a number of algorithms into our practice has enabled us to simplify the decision-making processes involved in microsurgical breast reconstruction and to consistently obtain successful surgical outcomes.

Polarized deep inelastic scattering experiments at CERN, DESY and SLAC have told us that quark partons contribute only about 30% of the proton's spin whereas relativistic quark models predict 60%. Where is the missing spin and why is the quark spin contribution so small? In this talk I will give an overview of the proton spin problem and what it may be telling us about QCD, the vacuum and dynamical symmetry breaking. A precise measurement of neutrino-proton elastic scattering would make a vital contribution to resolving many of the outstanding issues. Information: http://dpnc...

  18. The KCa3.1 blocker TRAM34 reverses renal damage in a mouse model of established diabetic nephropathy.

    Directory of Open Access Journals (Sweden)

    Chunling Huang

    Full Text Available Despite optimal control of hyperglycaemia, hypertension, and dyslipidaemia, the number of patients with diabetic nephropathy (DN continues to grow. Strategies to target various signaling pathways to prevent DN have been intensively investigated in animal models and many have been proved to be promising. However, targeting these pathways once kidney disease is established, remain unsatisfactory. The clinical scenario is that patients with diabetes mellitus often present with established kidney damage and need effective treatments to repair and reverse the kidney damage. In this studies, eNOS-/- mice were administered with streptozotocin to induce diabetes. At 24 weeks, at which time we have previously demonstrated albuminuria and pathological changes of diabetic nephropathy, mice were randomised to receive TRAM34 subcutaneously, a highly selective inhibitor of potassium channel KCa3.1 or DMSO (vehicle for a further 14 weeks. Albuminuria was assessed, inflammatory markers (CD68, F4/80 and extracellular matrix deposition (type I collagen and fibronectin in the kidneys were examined. The results clearly demonstrate that TRAM34 reduced albuminuria, decreased inflammatory markers and reversed extracellular matrix deposition in kidneys via inhibition of the TGF-β1 signaling pathway. These results indicate that KCa3.1 blockade effectively reverses established diabetic nephropathy in this rodent model and provides a basis for progressing to human studies.

    Different aspects of the construction of a building extension to the Geneva-Cointrin Airport in Switzerland are approached. At the end of the work, the airport will count six new gates. The priorities of the project are the comfort and the security of the passengers, the minimisation of energy consumption and environmental impact. A large part of the building facades is glassy favouring daylighting and natural space heating. In summer, a network of water-cooled tubes and plates hanging close to the ceiling makes up the air cooling. Globally, the airport fuel consumption has decreased since 1987, while the built surface has more than doubled. The installation, in 1996, of four Low-Nox burners in the thermal power plant also contributed to save primary energy.

  20. NPT: the issues facing the Geneva PrepCom

    The second session of the Preparatory Committee (PrepCom) for the 2015 Review Conference of the Parties to the Treaty on the Non- Proliferation of Nuclear Weapons (NPT) will meet from 22 April-3 May 2013 in Geneva, and will be chaired by Ambassador Cornel Feruta of Romania. Three years on from the adoption by consensus at the end of the 8. NPT Review Conference in New York of an Action Plan on non-proliferation, disarmament, and peaceful uses of nuclear energy - the three pillars of the NPT - as well as the Middle East, this session provides the opportunity both to take stock of the commitments undertaken in 2010 and to prepare the ground for the 2015 meeting. It is first worth noting that the beginning of the 9. five-year NPT review cycle in Vienna last year was marked by tangible optimism and revealed a constructive mindset on the part of the 110 delegations present. This was largely to be expected as a result of the success of the 2010 Review Conference. The two final PrepComs of 2010 cycle (Geneva in 2008 and New York in 2009) were also deemed a success by the delegations present, characterised by the rich and constructive nature of the discussion. Overall, the tension that marred the 2005 cycle has eased over the last few years. Yet, this positive development is sadly insufficient to ensure that the Treaty remains topical. Regarding the commitments undertaken in 2010 under the Action Plan, it is well known that it was impossible for the States concerned to come together in 2012 at a conference on establishment of a weapon-of-mass-destruction-free zone (WMDFZ) in the Middle East (chapter 4, 'The Middle East, particularly implementation of the 1995 Resolution on the Middle East'). Nevertheless, in accordance with the Action Plan, H.E. Mr Jaakko Laajava was appointed as the facilitator, Finland was named as the host country, and a rigorous consultative process is underway. Moreover, the EU has maintained its commitment to support this process by

    Prisoners have a right to health care and to be protected against inhumane and degrading treatment. Health care personnel and public policy makers play a central role in the protection of these rights and in the pursuit of public health goals. This article examines the legal framework for prison medicine in the canton of Geneva, Switzerland and provides examples of this framework that has shaped prisoners' medical care, including preventive measures. Geneva constitutes an intriguing example of how the Council of Europe standards concerning prison medicine have acquired a legal role in a Swiss canton. Learning how these factors have influenced implementation of prison medicine standards in Geneva may be helpful to public health managers elsewhere and encourage the use of similar strategies.

    The municipal, regional and national authorities wanted to assess the potential of electric-assisted bicycles in the Geneva region. A survey performed by the University of Geneva is reported. The following points were investigated: (i) Who uses an electric bicycle? (ii) How is an electric bicycle used? (iii) Why is an electric bicycle purchased? (iv) How many people could potentially use an electric bicycle in the Geneva region? (v) How much energy would be saved and what fraction of the carbon dioxide emissions would be avoided thanks to electric bicycles in the region? Some interesting results: Most current electric bicycle users are women and live in Geneva outskirts. Most users have an academic degree or equivalent and have a good job. Most of them have also a car and other bicycles without electric motor. The main uses of electric bicycles is commuting between house and job locations, leisure activities and shopping. The average annual distance per electric bicycle is about 3000 km. The majority of the electric bicycles in use are limited to 25 km/h and can be driven without any license. The users wish an extension of the bicycle track network along the roads and of the protected parking areas. The number of potential users in the City of Geneva is estimated to 9% or 15,600 new users and to 10% or 43,000 new users in the suburbs. In 2030, 7,500,000 litres-equivalent of gasoline could be annually saved in the region and more than 16,000 tons CO{sub 2} emissions avoided.

    Prison institutional conditions affect risk for self-harm among detainees. In particular, prison overcrowding may increase the likelihood of self-harm by creating competition for resources, space, and enhancing a "deprivation state." The purpose of this paper is to examine the association between overcrowding and prisoner acts of self-harm. This cross-sectional study took place at Geneva's pre-trial prison (capacity:376) between 2006 and 2014. Outcomes were acts of self-harm that required medical attention, and self-strangulation/hanging events (combined into one group, as these are difficult to differentiate). Dichotomous predictors were overcrowding index- annual mean daily population divided by capacity ( > 200 percent vs prison change in gender, area of origin, foreign residency, religion, or psychiatric treatment. The present study is limited by the definition and identification of self-harm. The distinction between self-strangulation and self-hanging, and the precise classification of an intent to die is difficult to make in practice, especially with limited prison data records available. The relevant literature addresses the complexity of the association between non-suicidal and suicidal behavior. Despite this, the combined category self-strangulations/hangings gives some indication of severe self-harm events, especially since the methodology of categorization employed was consistent throughout the entire period of the study. Other limitations include the small sample size and the lack of individual patient data and prison data to help control for confounding factors. Despite these drawbacks, pertinent data (socio-demographics and number of prisoners treated for mental health and drug abuse) remained stable over the years. Thus, there are no apparent changes in the inmate population that could be linked to an increase in self-harm. High-security placements and mean prisoner stay have increased over time, with a decrease in staff to prisoner ratio - and these

    2015-06-01

    Full Text Available Multimodal processes planning and scheduling play a pivotal role in many different domains including city networks, multimodal transportation systems, computer and telecommunication networks and so on. Multimodal process can be seen as a process partially processed by locally executed cyclic processes. In that context the concept of a Mesh-like Multimodal Transportation Network (MMTN in which several isomorphic subnetworks interact each other via distinguished subsets of common shared intermodal transport interchange facilities (such as a railway station, bus station or bus/tram stop as to provide a variety of demand-responsive passenger transportation services is examined. Consider a mesh-like layout of a passengers transport network equipped with different lines including buses, trams, metro, trains etc. where passenger flows are treated as multimodal processes. The goal is to provide a declarative model enabling to state a constraint satisfaction problem aimed at multimodal transportation processes scheduling encompassing passenger flow itineraries. Then, the main objective is to provide conditions guaranteeing solvability of particular transport lines scheduling, i.e. guaranteeing the right match-up of local cyclic acting bus, tram, metro and train schedules to a given passengers flow itineraries.

    2015-01-01

    Full Text Available This research study focused on the effect of using damping chamber elements made from waste tires on railway noise reduction. First, the energy absorption characteristics of damping chamber elements with various gradation combinations and compaction indices were measured in the laboratory using compression testing. The laboratory compression results demonstrated that the optimal gradation combination of damping chamber elements is as follows: the content of fine rubber particles is 10%, the content of coarse granules is 90%, and the optimal compaction index is 0.98. Next, the findings from the laboratory compression-test studies were used to produce damping chamber elements that were applied to a full-scale modern track model in the laboratory. The measurements of the dynamic properties indicated that the damping chamber elements could significantly reduce the vibration levels of the rail head. Finally, the damping chamber elements, which had been proven effective through laboratory dynamic tests, were widely applied to test rail sections in the field. The field tests demonstrated that damping chamber elements can significantly increase the track vibration decay rate in the frequency range of 200–10000 Hz. Therefore, damping chamber elements made from waste tires are able to control rail vibration and noise in modern tram track systems.

  19. Geneva Festival, 2004: Opened with the Big Bang, closed with Creation

    CERN Multimedia

    2004-01-01

    In its 50th Anniversary year, CERN had the honour of opening and closing this year's Geneva Festival. The Geneva Festival traditionally opens with a bang, but this year's was the biggest yet. On 30 July, on a warm summer's evening by Lake Geneva, several tons of fireworks replayed the early history of the Universe. Starting with the Big Bang, the display had acts representing inflation, the breaking of symmetries, the clash of antimatter and matter, hadrons and nucleosynthesis, the first atoms and the Universe becoming transparent, and the formation of stars and planets. It was a challenge to translate these very abstract ideas into more than a thousand kilograms of TNT of different colour. But, set to the music of The Matrix, Alan Parsons, and Jurassic Park, one of the most spectacular physics presentations ever staged dazzled the audience of two hundred thousand spectators. CERN physicist Rolf Landua, who scripted the narrative and worked with the pyrotechnicians on the realization, said: "From the many e...

  20. Underlying event sensitive observables in Drell-Yan production using GENEVA

    Alioli, Simone; Guns, Sam; Tackmann, Frank J.

    2016-11-09

    We present an extension of the GENEVA Monte Carlo framework to include multiple parton interactions (MPI) provided by PYTHIA8. This allows us to obtain predictions for underlying-event sensitive measurements in Drell-Yan production, in conjunction with GENEVA's fully-differential NNLO calculation, NNLL' resummation for the 0-jet resolution variable (beam thrust), and NLL resummation for the 1-jet resolution variable. We describe the interface with the parton shower algorithm and MPI model of PYTHIA8, which preserves both the precision of partonic N-jet cross sections in GENEVA as well as the shower accuracy and good description of soft hadronic physics of PYTHIA8. We present results for several underlying-event sensitive observables and compare to data from ATLAS and CMS as well as to standalone PYTHIA8 predictions. This includes a comparison with the recent ATLAS measurement of the beam thrust spectrum, which provides a potential avenue to fully disentangle the physical effects from the primary hard interact...

  1. Interacting forms of expertise in security governance: the example of CCTV surveillance at Geneva International Airport.

    Klauser, Francisco

    2009-06-01

    The paper investigates the multiple public-private exchanges and cooperation involved in the installation and development of CCTV surveillance at Geneva International Airport. Emphasis is placed on the interacting forms of authority and expertise of five parties: the user(s), owner and supplier of the camera system, as well as the technical managers of the airport and the Swiss regulatory bodies in airport security. While placing the issues of airport surveillance in the particular context of a specific range of projects and transformations relating to the developments of CCTV at Geneva Airport, the paper not only provides important insights into the micro-politics of surveillance at Geneva Airport, but aims to re-institute these as part of a broader 'problematic': the mediating role of expertise and the growing functional fragmentation of authority in contemporary security governance. On this basis, the paper also exemplifies the growing mutual interdependences between security and business interests in the ever growing 'surveillant assemblage' in contemporary security governance.

    Most helicopter data trends cannot be extrapolated to tiltrotors because blade geometry and aerodynamic behavior, as well as rotor and fuselage interactions, are significantly different for tiltrotors. A tiltrotor model has been developed to investigate the aeromechanics of tiltrotors, to develop a comprehensive database for validating tiltrotor analyses, and to provide a research platform for supporting future tiltrotor designs. The Full-Span Tiltrotor Aeroacoustic Model (FS TRAM) is a dual-rotor, powered aircraft model with extensive instrumentation for measurement of structural and aerodynamic loads. This paper will present the Full-Span TRAM test capabilities and the first set of data obtained during a 40- by 80-Foot Wind Tunnel test conducted in late 2000 at NASA Ames Research Center. The Full-Span TRAM is a quarter-scale representation of the V-22 Osprey aircraft, and a heavily instrumented NASA and U.S. Army wind tunnel test stand. Rotor structural loads are monitored and recorded for safety-of-flight and for information on blade loads and dynamics. Left and right rotor balance and fuselage balance loads are monitored for safety-of-flight and for measurement of vehicle and rotor aerodynamic performance. Static pressure taps on the left wing are used to determine rotor/wing interactional effects and rotor blade dynamic pressures measure blade airloads. All of these measurement capabilities make the FS TRAM test stand a unique and valuable asset for validation of computational codes and to aid in future tiltrotor designs. The Full-Span TRAM was tested in the NASA Ames Research Center 40- by 80-Foot Wind Tunnel from October through December 2000. Rotor and vehicle performance measurements were acquired in addition to wing pressures, rotor acoustics, and Laser Light Sheet (LLS) flow visualization data. Hover, forward flight, and airframe (rotors off) aerodynamic runs were performed. Helicopter-mode data were acquired during angle of attack and thrust sweeps for

    A reservoir assessment was performed in the Greater Geneva Basin to evaluate the geothermal resources potential of low to medium enthalpy (Moscariello, 2016). For this purpose, a detail structural analysis of the basin was performed (Clerc et al., 2016) simultaneously with a reservoir appraisal study including petrophysical properties assessment in a consistent sedimentological and stratigraphical frame (Brentini et al., 2017). This multi-disciplinary study was organised in 4 steps: (1) investigation of the surrounding outcrops to understand the stratigraphy and lateral facies distribution of the sedimentary sequence from Permo-Carboniferous to Lower Cretaceous units; (2) development of 3D geological models derived from 2D seismic and well data focusing on the structural scheme of the basin to constrain better the tectonic influence on facies distribution and to assess potential hydraulic connectivity through faults between reservoir units ; (3) evaluation of the distribution, geometry, sedimentology and petrophysical properties of potential reservoir units from well data; (4) identification and selection of the most promising reservoir units for in-depth rock type characterization and 3D modeling. Petrophysical investigations revealed that the Kimmeridgian-Tithonian Reef Complex and the underlying Calcaires de Tabalcon units are the most promising geothermal reservoir targets (porosity range 10-20%; permeability to 1mD). Best reservoir properties are measured in patch reefs and high-energy peri-reefal depositional environments, which are surrounded by synchronous tight lagoonal deposits. Associated highly porous dolomitized intervals reported in the western part of the basin also provide enhanced reservoir quality. The distribution and geometry of best reservoir bodies is complex and constrained by (1) palaeotopography, which can be affected by synsedimentary fault activity during Mesozoic times, (2) sedimentary factors such as hydrodynamics, sea level variations

    Similarly to steep oceanic continental margins, lake slopes can collapse, producing large sublacustrine landslides and tsunamis. Lake sediments are excellent natural archives of such mass movements and their study allows the reconstructions of these prehistoric events, such as the 563 AD large tsunami over Lake Geneva (Kremer et al, 2012). In Lake Geneva, more than 100 km of high-resolution seismic reflection profiles reveal the late Holocene sedimentation history. The seismic record shows a succession of five large lens-shaped seismic units (A to I), characterized by transparent/chaotic seismic facies with irregular lower boundaries, and interpreted as mass-movement deposits. These units are interbedded with parallel, continuous and strong amplitude reflections, interpreted as the 'background' lake sediments. The oldest dated mass movement (Unit D) covers a surface of 22 km2 in the deep basin, near the city of Lausanne. This deposit has an estimated minimum volume of 0.18 km3 and thus was very likely tsunamigenic (Kremer et al, 2012). A 12-m-long sediment core confirms the seismic interpretation of the mass movement unit and shows that the uppermost 3 m of Unit D are characterized by deformed hemipelagic sediments topped by a 5 cm thick turbidite. This deposit can be classified as a slump whose scar can be interpreted in the seismic data and visualized by multibeam bathymetry. This slump of Lausanne was likely triggered by an earthquake but a spontaneous slope collapse cannot be excluded (Girardclos et al, 2007). Radiocarbon dating of plant macro-remains reveals that the unit D happened during Early Bronze Age. Three other mass wasting deposits occurred during the same time period and may have been triggered during the same event, either by a single earthquake or by a tsunami generated by the slump of Lausanne. Although the exact trigger mechanism of the all these mass-wasting deposits remains unknown, a tsunami likely generated by this event may have affected the

    Sun and star trackers have been added to the latest version of the Geneva Observatory gondola. They perform an image motion compensation with an accuracy of plus or minus 1 minute of arc. The structure is held in the vertical position by gravity; the azimuth is controlled by a torque motor in the suspension bearing using solar or geomagnetic references. The image motion compensation is performed by a flat mirror, located in front of the telescope, controlled by pitch and yaw servo-loops. Offset pointing is possible within the solar disc and in a 3 degree by 3 degree stellar field. A T.V. camera facilitates the star identification and acquisition.

    2015-02-01

    At the Geneva Nomenclature Congress of 1892, some of the foremost organic chemists of the late nineteenth century crafted a novel relationship between chemical substances, chemical diagrams, and chemical names that has shaped practices of chemical representation ever since. During the 1880s, the French chemist Charles Friedel organised the nomenclature reform effort that culminated in the Geneva Congress; in the disorderly nomenclature of German synthetic chemistry, Friedel saw an opportunity to advance French national interests and his own pedagogical goals. Friedel and a group of close colleagues reconceived nomenclature as a unified field, in which all chemical names ought to relate clearly to one another and to the structure of the compounds they represented. The German chemist Adolf von Baeyer went a step farther, arguing for names that precisely and uniquely corresponded to the structural formula of each compound, tailored for use in chemical dictionaries and handbooks. Baeyer's vision prevailed at the Geneva Congress, which consequently codified rules for rigorously mapping structural formulas into names, resulting in names that faithfully represented the features of these diagrams but not always the chemical behaviour of the compounds themselves. This approach ultimately limited both the number of chemical compounds that the Geneva rules were able to encompass and the breadth of their application. However, the relationship between diagram and name established at the Geneva Congress became the foundation not only of subsequent systems of chemical nomenclature but of methods of organising information that have supported the modern chemical sciences.

Prof. Ursula Keller / Physics Department, ETH Zurich It is typically assumed that electrons can escape from atoms through tunneling when exposed to strong laser fields, but the timing of the process has been controversial, and far too rapid to probe in detail. We have used attosecond angular streaking [1] to place an upper limit of 34 attoseconds and an intensity-averaged upper limit of 12 attoseconds on the tunneling delay time in strong field ionization of a helium atom in the non-adiabatic tunneling regime [2]. This is the fastest process that has ever been measured. To achieve this we exploit the exact timing of a close to circular polarized intense laser field in t...

    Full Text Available Background: Cytomegalovirus (CMV is the most frequent cause of congenital infection and commonly associated with sensorineural deficit. At present, there is neither prophylaxis nor treatment during pregnancy. The objective of this study was to evaluate the level of awareness regarding CMV infection and its consequences in women delivering at the University of Geneva Hospitals (Geneva, Switzerland. Methods: The study consisted of a validated questionnaire completed by women in the immediate postpartum period. Results: The questionnaire was completed by 59% (314/528 of delivering women. Only 39% (123/314 knew about CMV and 19.7% (62/314 had received information about preventive measures. Women were more aware about other congenital diseases, such as toxoplasmosis (87%; human immunodeficiency virus (99%; syphilis (85.5%; rubella (92.3%; and group B Streptococcus (63%. Factors associated with CMV awareness were Swiss nationality, high education level, employment in health care or with children, and being followed by an obstetrician. Regarding quality of information, few were aware of the main CMV complications (deafness, 25.2%; mental retardation, 34.5%. Among those informed about CMV, most (74.6% knew about preventive measures. Among these, 82.5% thought that these were easily applicable. Conclusions: Most women were unaware of CMV infection and its potential risks during pregnancy. It is crucial to improve CMV information given to pregnant women to prevent the risks for the fetus/newborn.

  18. Values of the Wells and Revised Geneva Scores Combined with D-dimer in Diagnosing Elderly Pulmonary Embolism Patients

    Directory of Open Access Journals (Sweden)

    Dan-Jie Guo

    2015-01-01

    Full Text Available Background: Pulmonary embolism (PE can be difficult to diagnose in elderly patients because of the coexistent diseases and the combination of drugs that they have taken. We aimed to compare the clinical diagnostic values of the Wells score, the revised Geneva score and each of them combined with D-dimer for suspected PE in elderly patients. Methods: Three hundred and thirty-six patients who were admitted for suspected PE were enrolled retrospectively and divided into two groups based on age (≥65 or <65 years old. The Wells and revised Geneva scores were applied to evaluate the clinical probability of PE, and the positive predictive values of both scores were calculated using computed tomography pulmonary arteriography as a gold standard; overall accuracy was evaluated by the area under the curve (AUC of receiver operator characteristic curve; the negative predictive values of D-dimer, the Wells score combined with D-dimer, and the revised Geneva score combined with D-dimer were calculated. Results: Ninety-six cases (28.6% were definitely diagnosed as PE among 336 cases, among them 56 cases (58.3% were ≥65 years old. The positive predictive values of Wells and revised Geneva scores were 65.8% and 32.4%, respectively (P < 0.05 in the elderly patients; the AUC for the Wells score and the revised Geneva score in elderly was 0.682 (95% confidence interval [CI]: 0.612-0.746 and 0.655 (95% CI: 0.584-0.722, respectively (P = 0.389. The negative predictive values of D-dimer, the Wells score combined with D-dimer, and the revised Geneva score combined with D-dimer were 93.7%, 100%, and 100% in the elderly, respectively. Conclusions: The diagnostic value of the Wells score was higher than the revised Geneva score for the elderly cases with suspected PE. The combination of either the Wells score or the revised Geneva score with a normal D-dimer concentration is a safe strategy to rule out PE.

  20. Were Holocene large slumps in Lake Geneva off the city of Lausanne caused by fault activity?

    Science.gov (United States)

    Correia Demand, Jehanne; Marillier, François; Kremer, Katrina; Girardclos, Stéphanie

    2014-05-01

    Lake Geneva is set in an area where glacier advances and retreats have carved Tertiary Molasse rocks in front of the Alpine units. Glacial and lacustrine sediments have accumulated in the lake on top of the Molasse. Within Holocene sedimentary layers, seismic studies in the central part of Lake Geneva ("Grand-Lac") have shown the presence of several mass transport deposits (MTD). A large one, MTD A, is observed off the city of Lausanne. The depth of the associated failure scars (100 m water depth), its volume (~ 0.13 km3), and the occurrence of other smaller MTDs that were possibly co-deposited with MTD A point to the occurrence of a major slide event in the lake, most likely associated with an earthquake. Based on 14C dating, the sediment age model for MTD A gives an age interval of 1865-1608 BC (Kremer et al. 2014). To resolve the details of the MTDs off Lausanne, and to better understand its geological context different seismic systems were used. These were a 3.5 KHz pinger with a theoretical vertical resolution of 0.15 m and a multichannel system with water-gun or air-gun seismic sources with vertical resolution of 0.6 m and 1.1 m, respectively. After a first pass processing, the multi-channel data were reprocessed in order to take into account the shape of the streamer in the water and to enhance the results of migration. In addition to typical seismic images of MTDs observed in other alpine lakes such as chaotic or transparent seismic character between well-organized reflections, two intriguing positive water-bottom topographic features associated with apparent sub-vertical offsets are revealed by the seismic data. They are located in the near vicinity of the depot centers of the MTDs and conspicuously located near faults in the Tertiary Molasse. These are thrust faults that are offset by small strike-slip faults, and we suggest that the positive topographic features are linked to a compressive component within the sediments due to displacements along these

    Tenckhoff; Brand, B.; Weiss, P.

    1993-06-01

    The UPTF TRAM test A3 was a separate effects test to investigate the interaction between the hot leg-injected ECC and the single-phase or two-phase natural circulation in the hot leg in the case of an SBLOCA in a PWR. The experimental investigation of 7 runs was mainly concentrated on the following phenomena: - Transport of hot leg injected ECC water to the upper plenum or in the direction of steam generator, depending on the loop mass flow, -Utilization of the condensation potential of ECC water, - Mixing of the saturated water with the ECC water, - Effect of hot leg injection on the flow phenomena in the hot leg, - Effect of pressure (3 and 15 bar) on the scaling and hence the verification of the scaling concept applied. A preliminary evaluation of the test is presented in the Quick Look Report. (orig.) [de

    Klersy, R.

    1956-01-01

    The author proposes a critical synthesis of contributions to Geneva Proceedings: a Russian one (The effect of irradiation on the structure and properties of the structural materials), a British one (Radiation damage in non-fissile materials), an American one (The theory of lattice displacements produced during irradiation), and some others sometimes evoked. After a brief assessment of the experimental and theoretical interest of these contributions, the author addresses various issues and outlines how these contributions addressed them: mechanical and thermal tests (elasticity modulus, dilatation, failure characteristics of pure metals and alloys, resilience, hardness, effect of radiation on hardness of metals previously submitted to various strain hardening, creep, fatigue), resistivity of pure metals (copper, iron, cobalt, nickel, tungsten) submitted to deuteron or proton irradiation, behaviour of ordered alloys, recovery of irradiation effects

    Full Text Available Treated wastewater and runoff-water is released by the outlet of the sewage treatment plant of Vidy (Lausanne directly into the Lake of Geneva via a pipe located 300m from the shore. Even if this water is properly treated with modern technologies, we can observe an accumulation of micro pollutants into the sediments, and particularly heavy-metals. The main objective of this project is to investigate how these elevated concentrations of heavy metals affect both abundance and diversity of prokaryotes in the sediments. A special emphasis was given to endospore-forming bacteria, which could use sporulation as a survival strategy to resist in highly contaminated areas. This study could have implications both for understanding the role of endospore-forming bacteria in the environment as well as in terms of improving the bioremediation processes.

    Full Text Available The article aims to investigate the Calvin’s Genevan Service Order. It focuses on the question how the Psalter Calvin shaped the worship of the Reformed Church in Geneva. The article follows the critical edition of the Genevan prayer in Calvini Opera Selecta and in the German Studienausgabe as the two main published editions of the Genevan order with its related texts. The article shows that Calvin adhered to the general line of the Swiss and Upper German Reformations. It explores the understanding of worship reflected in the Genevan Service Order and the specific significance of its musical aspect. The article illustrates why Calvin gave the psalms the place he did in Genevan Reformed worship.

  6. Presidential speech given to the general assembly of the UCS on 22 August 1980 in Geneva

    The speech to the Geneva conference relates to recent and future developments in Switzerland in the production of electricity. Total electricity consumption in Switzerland fell by 1.7% during the 1975 recession, but otherwise has continued to grow steadily and is expected to increase at about 3.7% annually until 1984 and 2.5% thereafter. Hydro-electricity has contributed 71% of total electricity generation so far. References are made to the recent legal changes permitting increased use in nuclear energy and to nuclear stations already built or under development. In other energy consumption fields, natural gas has expanded most rapidly, almost three times in 10 years. Expansion into oil usage was retarded by the Middle East crisis. Some plans made for rationing electricity consumption to meet future crises are quoted. (G.C.)

    Air pollution is one of the leading environmental problems of out times that could eventually change the living conditions of human beings and the ecosystems on the whole planet. Therefore, international forums have been created to discuss environmental policies aimed at the control of pollutant emissions and the protection of ecosystems and human health. the fundamental purpose is to take common actions that go beyond political borders, since in many cases the emissions of pollutants affect ecosystems far from the emission source. These were the objectives leading to the creation of the Geneva Convention on Long-Range Transboundary Air Pollution, of the Economic commission for Europe-United Nations (UNECE). (Author) 12 refs.

    2018-01-01

    We present a speckle survey of Hipparcos visual doubles and spectroscopic binary stars identified by the Geneva-Copenhagen spectroscopic survey with the SOAR 4m telescope + HRCam. These systems represent our best chance to take advantage of Gaia parallaxes for the purpose of stellar mass determinations. Many of these systems already have mass fractions (although generally no spectroscopic orbit - an astrometric orbit will determine individual masses), metallicity information, and Hipparcos distances. They will be used to improve our knowledge of the mass-luminosity relation, particularly for lower-metallicity stars. Our survey will create the first all-sky, volume-limited, speckle archive for the two primary samples, complementing a similar effort that has been recently been completed at the WIYN 3.5-m telescope in the Northern Hemisphere. This extension to the Southern Hemisphere will fill out the picture for a wider metallicity range.

  10. Geochemical Dataset of the Rhone River Delta (Lake Geneva) Sediments - Disentangling Human Impacts from Climate Change

    Lake sediment records are often the most complete continental archives. In the last 200 years, in addition to climatic variability, humans have strongly impacted lake watersheds around the world. During the 20th century the Rhone River and its watershed upstream Lake Geneva (Switzerland/France) have been subject to river channelization, dam construction, water flow regulation, water and sediment abstraction as well as various land use changes. Under the scope of the SEDFATE project (Swiss National Science Foundation nº147689) we address human and climatic impact on the sediment transfer from the Rhone River watershed to Lake Geneva. Nineteen short sediment cores were collected in the Rhone River delta area in May 2014. Cores have been scanned with MSCL and XRF, sub-sampled every 1cm and 8 cores were dated by radiometric methods (137Cs and 210Pb). Photographs taken right after core opening were used for lithological description and in addition to MSCL data were used to correlate cores. Core dating shows that mass accumulation rates decreased in the 1964-1986 interval and then increased again in the interval between 1986-2014. XRF elements and ratios, known to indicate detrital sources (Al, Al/Si, Fe, K, Mn, Rb, Si, Ti, Ti/Ca), show that clastic input diminished from 1964 to 1986 and re-increased to the present. Other elemental (Zr/Rb, Zr/K, Si/Ti) and geophysical data (magnetic susceptibility) combined with lithology identify density flow deposits vs hemipelagic sedimentation. Changes in frequency of these event deposits indicate changes in the sedimentation patterns in the Rhone River sublacustrine delta during the last century. From these results we hypothesize that a significant sediment amount was abstracted from the system after the major dam constructions in the 1950's and that, since the 1990's, a contrary signal is due to increased sediment loads that follows glacial melting due to global warming.

  11. Acute respiratory and cardiovascular admissions after a public smoking ban in Geneva, Switzerland.

    Directory of Open Access Journals (Sweden)

    Jean-Paul Humair

    Full Text Available BACKGROUND: Many countries have introduced legislations for public smoking bans to reduce the harmful effects of exposure to tobacco smoke. Smoking bans cause significant reductions in admissions for acute coronary syndromes but their impact on respiratory diseases is unclear. In Geneva, Switzerland, two popular votes led to a stepwise implementation of a state smoking ban in public places, with a temporary suspension. This study evaluated the effect of this smoking ban on hospitalisations for acute respiratory and cardiovascular diseases. METHODS: This before and after intervention study was conducted at the University Hospitals of Geneva, Switzerland, across 4 periods with different smoking legislations. It included 5,345 patients with a first hospitalisation for acute coronary syndrome, ischemic stroke, acute exacerbation of chronic obstructive pulmonary disease, pneumonia and acute asthma. The main outcomes were the incidence rate ratios (IRR of admissions for each diagnosis after the final ban compared to the pre-ban period and adjusted for age, gender, season, influenza epidemic and secular trend. RESULTS: Hospitalisations for acute exacerbation of chronic obstructive pulmonary disease significantly decreased over the 4 periods and were lowest after the final ban (IRR=0.54 [95%CI: 0.42-0.68]. We observed a trend in reduced admissions for acute coronary syndromes (IRR=0.90 [95%CI: 0.80-1.00]. Admissions for ischemic stroke, asthma and pneumonia did not significantly change. CONCLUSIONS: A legislative smoking ban was followed by a strong decrease in hospitalisations for acute exacerbation of chronic obstructive pulmonary disease and a trend for reduced admissions for acute coronary syndrome. Smoking bans are likely to be very beneficial for patients with chronic obstructive pulmonary disease.

    Syphilis has been reinstated on the list of notifiable diseases in Switzerland since 2006 and the active management of sexual partners is encouraged to avoid reinfection. However, contact tracing has yielded unsatisfactory results and the incidence of syphilis remains important, especially in high-risk populations. The aim of this study was to compare the proportions of notified sexual partners of patients diagnosed with syphilis by the laboratories of Geneva University Hospitals (HUG) with those diagnosed in private laboratories (non-HUG) and to assess the risk factors for no notification to sexual partners. All syphilis cases notified to the Office of the Surgeon General in Geneva (Switzerland) between 1 January 2011 and 31 December 2013 were analysed. The proportions of partner notification (PN) between HUG and non-HUG laboratories were compared by Chi square test and the main risk factors for no notification to sexual partners were assessed by binomial log-linear regression. Among a total of 720 notifications reported, 244 cases were diagnosed with contagious syphilis stages and 263 with non-contagious stages (i.e. successfully treated patients with or late latent cases). Overall, PN was higher among contagious than non-contagious cases (58.4% versus 31.0%; p = 0.030) and it was significantly higher in the non-HUG compared to the HUG group (75.9% versus 50.0%, respectively; p 45 years (RR 1.36; 95% CI: 1.05-1.76) and if the patient had received treatment for syphilis (RR 1.91; 95% CI: 1.38-2.66). Our results illustrate the difficulty of contact tracing in syphilis infection and the necessity to improve this crucial part of sexually transmitted infection management.

  13. Geothermal prospection in the Greater Geneva Basin (Switzerland and France): Integration of geological data in the new Information System

    2017-04-01

    Piloted by the State of Geneva and implemented by the SIG (Services Industriels de Genève), the GEothermie2020 program aims to develop geothermal energy resources in the Greater Geneva Basin (GGB) (Moscariello A., 2016). Since 2014, many existing data have been examined (Rusillon et al., 2017, Clerc et al., 2016) and new ones have been collected. Nevertheless, to date the actual IT infrastructure of the State of Geneva is neither designed to centralize these data, nor to respond efficiently to operational demands. In this context, we are developing a new Information System adapted to this specific situation (Favre et al., 2017). In order to establish a solid base line for future exploration and exploitation of underground natural resources, the centralization of the geological surface/subsurface knowledge is the real challenge. Finding the balance between comprehensiveness and relevance of the data to integrate into this future complete database system is key. Geological data are numerous, of various nature, and often very heterogeneous. Incorporating and relating all individual data is therefore a difficult and challenging task. As a result, a large work has to be done on the understanding and the harmonization of the stratigraphy of the Geneva Basin, to appreciate the data and spatial geological heterogneity. The first step consisted in consulting all data from MSc and PhD work of the University of Geneva (about 50) and from literature concerning the regional geology. In parallel, an overview concerning the subsurface geological data management in Europe carried out to learn from the experience of other geological surveys. Heterogeneities and discrepancies of the data are the main issue. Over several years (since late 30s) individual authors collected different type of data and made different interpretations leading a variety of stratigraphic facies definitions, associations and environmental reconstructions.

    The Third Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons will be held in Geneva, Switzerland, in 1985 with a view to assuring that the purposes and provisions of the Treaty are being realized. The Treaty, commonly referred to as the non-proliferation Treaty, is the fundamental instrument to avert the danger of proliferation of nuclear weapons and is, perhaps, the most important multilateral arms regulation agreement of our time. It was negotiated in the 1960s in the Eighteen-Nation Committee on Disarmament in Geneva and in the United Nations General Assembly. The Treaty was opened for signature in London, Moscow and Washington on July 1, 1968. On that date, it was signed by the three Depositary Governments - the Soviet Union, the United Kingdom and the United States - and by 58 other States. As of December 31, 1983 the number of States parties to the Treaty had risen to 119

    We extend the lowest-order matching of tree-level matrix elements with parton showers to give a complete description at the next higher perturbative accuracy in {alpha}{sub s} at both small and large jet resolutions, which has not been achieved so far. This requires the combination of the higher-order resummation of large Sudakov logarithms at small values of the jet resolution variable with the full next-to-leading order (NLO) matrix-element corrections at large values. As a by-product, this combination naturally leads to a smooth connection of the NLO calculations for different jet multiplicities. In this paper, we focus on the general construction of our method and discuss its application to e{sup +}e{sup -} and pp collisions. We present first results of the implementation in the GENEVA Monte Carlo framework. We employ N-jettiness as the jet resolution variable, combining its next-to-next-to-leading logarithmic resummation with fully exclusive NLO matrix elements, and PYTHIA 8 as the backend for further parton showering and hadronization. For hadronic collisions, we take Drell-Yan production as an example to apply our construction. For e{sup +}e{sup -} {yields} jets, taking {alpha}{sub s}(m{sub Z}) = 0.1135 from fits to LEP thrust data, together with the PYTHIA 8 hadronization model, we obtain good agreement with LEP data for a variety of 2-jet observables.

    Full Text Available Over 3,000 samples of plastic litter have been retrieved from 12 pebble beaches around the shores of Lake Geneva. The plastic stock consisted of identifiable objects of various size and color, including bottles, bottle tops, cotton buds, pens, toys, and straws, an heterogeneous assortment of fragments whose origin was either discernible or unknown, and pieces or blocks of expanded polymer (polystyrene or polyurethane foam. Analysis of 670 samples by portable x-ray fluorescence (XRF spectrometry revealed high concentrations of hazardous elements or compounds among many plastics. These included Cd, Hg, and Pb (with maximum concentrations of 6,760, 810, and 23,500 ppm, respectively as stabilizers in PVC-based materials and/or brightly-colored sulfide or chromate pigments in primary and secondary plastics, and Br (with a maximum concentration of 27,400 ppm as a proxy for brominated flame retardants (BFRs in both plastics and foams. The abundance of hazardous elements in beached plastics that have been restricted or banned reflect the age and residence time of the plastic stock in the lake, coupled with a relatively high length of shoreline to surface area of the system. The migratability of hazardous elements from the polymeric matrix is likely to determine their environmental impacts and is recommended as a future area of research.

  7. Equitable access to spectrum in further development of the Geneva 2006 frequency plan

    Philipp, J.

    2011-12-01

    Since the frequency plan of the Regional Radiocommunication Conference Geneva 2006 has come into force, many attempts have been made towards its enhancement. The preliminary results, however, seem not to be compliant with elementary principles of distribution justice. Therefore, the planning principles which lead to the observed imbalance will be scrutinized. Furthermore it will be shown that the utilization of spectrum can be advanced in a balanced way when the same (necessary) condition for "equitable access", which has been used by a group of middle European countries for the construction of the original frequency plan, is applied to plan refinements as well. The necessary condition mentioned consists simply in the parity of the number of coverages (constituted of disjoint allotments) configured in the plan for each country. In order to be able to plan enhancements, the concept of coverage number has to be generalized to the case of incomplete coverages of potentially overlapping allotments. The computation of coverage numbers is straightforward and renders the concept of coverage number parity a useful tool to be applied as a necessary condition in testing a frequency plan variant for equitable access.

    Back in April 2002, AFAS and the "Club de Marseille" jointly convened "World-Med 2002". That meeting was about sharing knowledge between the North and the South of the Mediterranean. The purpose was to show how concrete projects, born from within the civil society, could advance cooperation between countries belonging to different cultures, thereby providing a much-needed stimulus to the political intergovernmental process. The meeting was attended by 850 people, of which 150 came from North Africa. We were delighted to hear that several important projects were indeed born as a result of contacts initiated among the participants. In order to follow-up on that success, AFAS is convening on 6 and 7 May at CERN, Geneva, a smaller meeting (limited to 100 participants) during which we will revisit some of the topics that appeared as promising during "World-Med 2002". This should be seen as the beginning of a series and we will therefore propose that subsequent meetings deal with those important themes that we will...

  9. Training medical students in human rights: a fifteen-year experience in Geneva

    Directory of Open Access Journals (Sweden)

    Philippe Chastonay

    2012-09-01

    Full Text Available Background: Training health professionals in the field of human rights has long been advocated by the United Nations. Over the past decade some medical schools have introduced health and human rights courses, yet by far not all. This paper describes the objectives and the content of the Health and Human Rights program developed at the Faculty of Medicine, University of Geneva. Methods: The health and human rights program was developed through the identification of the course objectives, contents, and educational modalities using consensus techniques, and through a step by step implementation procedure integrating multiple evaluation processes. Results: Defined objectives included the familiarization with the concepts, instruments and mechanisms of human rights, the links between health and human rights, and the role of health professionals in promoting human rights. The content ultimately adopted focused on the typology of human rights, their mechanisms of protection, their instruments, as well as social inequalities and vulnerable groups of the population. The implementation proceeded through a step by step approach. Evaluation showed high satisfaction of students, good achievement of learning objectives, and some academic and community impact. Conclusions: High interest of students for a human rights course is encouraging. Furthermore, the community projects initiated and implemented by students may contribute to the social responsibility of the academic institution.

  10. The EU in Geneva: The Diplomatic Representation of a System of Governance

    Directory of Open Access Journals (Sweden)

    Caterina Carta

    2013-07-01

    Full Text Available The European Union (EU diplomatic system can be conceived as representative of a system of governance, and, through this, of its constitutive independent units. The way in which the EU's political system is represented through diplomatic practices is telling of two interrelated aspects of the EU's international actorness. First, it reveals the link between the foreign policy of a non-state actor and sheds light on the division of competences that characterises the EU's foreign policy-making system. Second, it highlights the complex institutional and organisational features of a non-state diplomatic system. This article locates the puzzle of EU diplomatic activity in the general debate about changes in the institution of diplomacy. Secondly, it explains how post-Lisbon institutional arrangements have been translated into practice in two multilateral delegations: the delegation to the UN and the mission to the WTO in Geneva. It finally draws some preliminary conclusions. The article concludes that beyond competition over the attribution of competences in the EU’s diplomatic governance, different ideas coexist about what ‘locating the EU in the international scene’ means. Pursuing a ‘single voice’ by unifying forms of external representation is not necessarily perceived as the most convenient strategy envisaged by all EU actors. While institutional actors tend to believe that coherence and strength may descend from a more unified system of representation, the member states tend to believe that, in certain circumstances, differentiation could increase the EU’s strength.

  19. Extreme climate, not extreme weather: the summer of 1816 in Geneva, Switzerland

    2012-02-01

    Full Text Available We analyze weather and climate during the "Year without Summer" 1816 using sub-daily data from Geneva, Switzerland, representing one of the climatically most severely affected regions. The record includes twice daily measurements and observations of air temperature, pressure, cloud cover, wind speed, and wind direction as well as daily measurements of precipitation. Comparing 1816 to a contemporary reference period (1799–1821 reveals that the coldness of the summer of 1816 was most prominent in the afternoon, with a shift of the entire distribution function of temperature anomalies by 3–4 °C. Early morning temperature anomalies show a smaller change for the mean, a significant decrease in the variability, and no changes in negative extremes. Analyzing cloudy and cloud-free conditions separately suggests that an increase in the number of cloudy days was to a significant extent responsible for these features. A daily weather type classification based on pressure, pressure tendency, and wind direction shows extremely anomalous frequencies in summer 1816, with only one day (compared to 20 in an average summer classified as high-pressure situation but a tripling of low-pressure situations. The afternoon temperature anomalies expected from only a change in weather types was much stronger negative in summer 1816 than in any other year. For precipitation, our analysis shows that the 80% increase in summer precipitation compared to the reference period can be explained by 80% increase in the frequency of precipitation, while no change could be found neither in the average intensity of precipitation nor in the frequency distribution of extreme precipitation. In all, the analysis shows that the regional circulation and local cloud cover played a dominant role. It also shows that the summer of 1816 was an example of extreme climate, not extreme weather.

    Cryptosporidium, a protozoan parasite that can cause severe diarrhea in a wide range of vertebrates including humans, is increasingly recognized as a parasite of a diverse range of wildlife species. However, little data are available regarding the identification of Cryptosporidium species and genotypes in wild aquatic environments, and more particularly in edible freshwater fish. To evaluate the prevalence of Cryptosporidiumspp. in fish from Lake Geneva (Lac Léman) in France, 41 entire fish and 100 fillets (cuts of fish flesh) were collected from fishery suppliers around the lake. Nested PCR using degenerate primers followed by sequence analysis was used. Five fish species were identified as potential hosts of Cryptosporidium: Salvelinus alpinus, Esox lucius, Coregonus lavaretus, Perca fluviatilis, and Rutilus rutilus. The presence of Cryptosporidium spp. was found in 15 out of 41 fish (37%), distributed as follows: 13 (87%) C. parvum, 1 (7%) C. molnari, and 1 (7%) mixed infection (C. parvum and C. molnari). C. molnari was identified in the stomach, while C. parvum was found in the stomach and intestine. C. molnari was also detected in 1 out of 100 analyzed fillets. In order to identify Cryptosporidium subtypes, sequencing of the highly polymorphic 60-kDa glycoprotein (gp60) was performed. Among the C. parvum positive samples, three gp60 subtypes were identified: IIaA15G2R1, IIaA16G2R1, and IIaA17G2R1. Histological examination confirmed the presence of potential developmental stages of C. parvum within digestive epithelial cells. These observations suggest that C. parvum is infecting fish, rather than being passively carried. Since C. parvum is a zoonotic species, fish potentially contaminated by the same subtypes found in terrestrial mammals would be an additional source of infection for humans and animals, and may also contribute to the contamination of the environment with this parasite. Moreover, the risk of human transmission is strengthened by the

    Artificial stocking practices are widely used by resource managers worldwide, in order to sustain fish populations exploited by both recreational and commercial activities, but their benefits are controversial. Former practices involved exotic strains, although current programs rather consider artificial breeding of local fishes (supportive breeding). Understanding the complex genetic effects of these management strategies is an important challenge with economic and conservation implications, especially in the context of population declines. In this study, we focus on the declining Arctic charr ( Salvelinus alpinus ) population from Lake Geneva (Switzerland and France), which has initially been restocked with allochtonous fishes in the early eighties, followed by supportive breeding. In this context, we conducted a genetic survey to document the evolution of the genetic diversity and structure throughout the last 50 years, before and after the initiation of hatchery supplementation, using contemporary and historical samples. We show that the introduction of exotic fishes was associated with a genetic bottleneck in the 1980-1990s, a break of Hardy-Weinberg Equilibrium (HWE), a reduction in genetic diversity, an increase in genetic structure among spawning sites, and a change in their genetic composition. Together with better environmental conditions, three decades of subsequent supportive breeding using local fishes allowed to re-establish HWE and the initial levels of genetic variation. However, current spawning sites have not fully recovered their original genetic composition and were extensively homogenized across the lake. Our study demonstrates the drastic genetic consequences of different restocking tactics in a comprehensive spatiotemporal framework and suggests that genetic alteration by nonlocal stocking may be partly reversible through supportive breeding. We recommend that conservation-based programs consider local diversity and implement adequate

  3. A Multiscale Surface Water Temperature Data Acquisition Platform: Tests on Lake Geneva, Switzerland

    An improved understanding of surface transport processes is necessary to predict sediment, pollutant and phytoplankton patterns in large lakes. Lake surface water temperature (LSWT), which varies in space and time, reflects meteorological and climatological forcing more than any other physical lake parameter. There are different data sources for LSWT mapping, including remote sensing and in situ measurements. Satellite data can be suitable for detecting large-scale thermal patterns, but not meso- or small scale processes. Lake surface thermography, investigated in this study, has finer resolution compared to satellite images. Thermography at the meso-scale provides the ability to ground-truth satellite imagery over scales of one to several satellite image pixels. On the other hand, thermography data can be used as a control in schemes to upscale local measurements that account for surface energy fluxes and the vertical energy budget. Independently, since such data can be collected at high frequency, they can be also useful in capturing changes in the surface signatures of meso-scale eddies and thus to quantify mixing processes. In the present study, we report results from a Balloon Launched Imaging and Monitoring Platform (BLIMP), which was developed in order to measure the LSWT at meso-scale. The BLIMP consists of a small balloon that is tethered to a boat and equipped with thermal and RGB cameras, as well as other instrumentation for location and communication. Several deployments were carried out on Lake Geneva. In a typical deployment, the BLIMP is towed by a boat, and collects high frequency data from different heights (i.e., spatial resolutions) and locations. Simultaneous ground-truthing of the BLIMP data is achieved using an autonomous craft that collects a variety of data, including in situ surface/near surface temperatures, radiation and meteorological data in the area covered by the BLIMP images. With suitable scaling, our results show good consistency

  4. Quorum-dependent transfer of the opine-catabolic plasmid pAoF64/95 is regulated by a novel mechanism involving inhibition of the TraR antiactivator TraM.

    We previously described a plasmid of Agrobacterium spp., pAoF64/95, in which the quorum-sensing system that controls conjugative transfer is induced by the opine mannopine. We also showed that the quorum-sensing regulators TraR, TraM, and TraI function similarly to their counterparts in other repABC plasmids. However, traR, unlike its counterpart on Ti plasmids, is monocistronic and not located in an operon that is inducible by the conjugative opine. Here, we report that both traR and traM are expressed constitutively and not regulated by growth with mannopine. We report two additional regulatory genes, mrtR and tmsP, that are involved in a novel mechanism of control of TraR activity. Both genes are located in the distantly linked region of pAoF64/95 encoding mannopine utilization. MrtR, in the absence of mannopine, represses the four-gene mocC operon as well as tmsP, which is the distal gene of the eight-gene motA operon. As judged by a bacterial two-hybrid analysis, TmsP, which shows amino acid sequence relatedness with the TraM-binding domain of TraR, interacts with the antiactivator. We propose a model in which mannopine, acting through the repressor MrtR, induces expression of TmsP which then titrates the levels of TraM thereby freeing TraR to activate the tra regulon. © 2018 The Authors.

    The project with name GGP ('Geothermie de Grande Profondeur') pertains to deep heat mining in the region of Geneva, Switzerland. Seismic observations have shown that the original idea of using an exploratory borehole down to a depth of 3,700 meters is justified. A suitable location for this drilling experiment including additional geological investigations could be found in the near community of Bernex. Another advantage of this location is that its existing district heating system including an industrial compound of the City of Geneva is well suited for distributing the heat produced by the future geothermal pilot plant. Engineers also suggest that the combination with a gas turbine could be an interesting solution for Geneva. The GGP project has been repeatedly promoted by talks and reports in the daily press as well as in radio and TV programmes. In addition, an easily understandable leaflet has been made available.

    The "Universal Declaration of Human Rights" and the "Geneva Declaration" by the World Medical Association, both in 1948, were preceded by the foundation of the United Nations in New York (1945), the World Medical Association in London (1946) and the World Health Organization in Geneva (1948). After the end of World War II the community of nations strove to achieve and sustain their primary goals of peace and security, as well as their basic premise, namely the health of human beings. All these associations were well aware of the crimes by medicine, in particular by the accused Nazi physicians at the Nuremberg Doctors Trial (1946/47, sentence: August 1947). During the first conference of the World Medical Association (September 1947) issues of medical ethics played a major role: and a new document was drafted concerning the values of the medical profession. After the catastrophe of the War and the criminal activities of scientists, the late 1940s saw increased scrutiny paid to fundamental questions of human rights and medical ethics, which are still highly relevant for today's medicine and morality. The article focuses on the development of medical ethics and human rights reflected in the statement of important persons, codes and institutions in the field.

    Full Text Available The present article, developed out of a research project which lasted several years, analyses the tensions between, on one side, Romanian Roma back-and-forth migrants, and on the other side, Geneva's police. In the last decade, these tensions are mostly linked to begging (an activity which provides small daily incomes to the majority of the 250 Romanian Roma living in the city, that is since 2007 a crime. These tensions between police officers and Roma are part of a wider European punishing-the-poor urban governance model, and bring to the exclusion of other actors from the public action. Through the interaction between the moral and symbolic violence linked to police intervention, the high visibility of Roma in public place and their reconnection with previous experiences, such tensions re-create the ethnic divide between Roma and non-Roma. As a consequence, Roma who have their roots in rural and peri-urban Transylvania use their “village making” practices to perform a symbolic and social appropriation of the town notwithstanding “anti-Gypsy” repression. The “village making” of the Roma becomes thus a specific form of response in a context  (Geneva and more generally Switzerland where the occupation of urban and peri-urban territory through the “camps” experienced in other European towns does not exist.

Examination by scanning electron microscopy revealed the presence of numerous dark and gelatinous patches occluding the pores of the membranes, containing high numbers of picoplanktonic cells and, in places, clusters of high-reflectance smooth microspheres (1-2 μm in diameter. Their chemical composition, determined by semi-quantitative, energy-dispersive X ray spectroscopy (EDS showed magnesium (Mg, calcium (Ca, strontium (Sr and barium (Ba (alkaline earth metals to be the dominant cations. Among the anions, phosphorus (P and carbon (C were present, but only the latter is considered here (as carbonate. The microspheres were subdivided into four types represented in a Ca-Sr-Ba ternary space. All types are confined within a domain bound by Ca>45, Sr<10 and Ba<50 (in mole %. Type I, the most frequent, displays a broad variability in Ba/Ca, even within a given cluster. Types II and III are devoid of Ba, but may incorporate P. Type IV contains only Ca.

    Full Text Available Abstract Background Prostate cancer is the most commonly diagnosed malignancy in men in Sweden and Geneva, and the third most common in men in Singapore. This population-based study describes trends in the incidence and mortality rates of prostate cancer in Singapore, Sweden and Geneva (Switzerland from 1973 to 2006 and explores possible explanations for these different trends. Methods Data from patients diagnosed with prostate cancer were extracted from national cancer registries in Singapore (n = 5,172, Sweden (n = 188,783 and Geneva (n = 5,755 from 1973 to 2006. Trends of incidence and mortality were reported using the Poisson and negative binomial regression models. The age, period and birth-cohort were tested as predictors of incidence and mortality rates of prostate cancer. Results Incidence rates of prostate cancer increased over all time periods for all three populations. Based on the age-period-cohort analysis, older age and later period of diagnosis were associated with a higher incidence of prostate cancer, whereas older age and earlier period were associated with higher mortality rates for prostate cancer in all three countries. Conclusions This study demonstrated an overall increase in incidence rates and decrease in mortality rates in Singapore, Sweden and Geneva. Both incidence and mortality rates were much lower in Singapore. The period effect is a stronger predictor of incidence and mortality of prostate cancer than the birth-cohort effect.

    2005-12-01

    Full Text Available We examined 267 red foxes (Vulpes vulpes from the canton of Geneva, Switzerland, for intestinal infections with Echinococcus multilocularis. This region is situated in the core area of the endemic range of this zoonotic cestode in Central Europe. Several factors were taken into account and urbanisation level appeared to be the most explicative to describe observed differences. The prevalence decreased significantly from rural and residential areas (prevalence of 52 %, CI 43-62 %, and 49 %, CI 38-59 %, respectively to the urban area (prevalence of 31 %, CI 19-42 %. A few juvenile foxes harboured very high burdens up to more than 120,000 worms and were significantly more heavily infected than adults. The intensity of infection decreased from rural and residential areas to the city, suggesting a lower contamination of the urban environment.

    During the eighteenth century, several towns located in what is known today as the Suisse romande were extremely receptive toward scientific culture, and most notably Newtonianism. In this paper I deal with a nine-volume publication of Newton's Opera Omnia that was planned in Geneva and Lausanne during the late 1730s and 1740s. This publication has not received the attention it deserves. To the best of my knowledge, even an awareness of its existence is lacking in the literature devoted to the reception of Newtonianism. This paper examines the circumstances of the publication of a complete set of all of Newton's works known at the time, and the motivations of the editors, mathematicians, and publishers who were involved in this editorial enterprise.

    Examine whether an overconsumption of tranquillizers exists in prison and discuss possible reasons. Comparative study during three weeks at Geneva: prison outpatient service and Medical Policlinic (MP) of the University Hospital. When comparing the 113 (prison) and 151 (MP) male patients younger than 39 years, we found important differences concerning the quality and quantity of prescriptions of psychoactive drugs: ten times more prison patients than patients from the MP were treated with benzodiazepines (BZD). The differences persisted even when considering only prisoners who were not known to be street drug, alcohol or long time BZD consumers. The differences cannot be explained by the high percentage of drug addicts in prison. Our results suggest the importance of factors related to the prison environment.

    Turbidites recorded in lake sediments are often used to reconstruct the frequency of past flood and also seismological events. However, for such a reconstruction, the origin and causes of the recorded turbidites need to be clearly identified. In this study, we test if turbidites can be used as paleohydrological archive based on the the sedimentary record of Lake Geneva resulting from inputs by the Rhone and Dranse clastic river systems. Our approach is based on several methods combining high-resolution seismic reflection data with geophysical (magnetic susceptibility, grain size) and high-resolution XRF/XRD data measured on ca. 10-m-long sediment cores (dated by radiocarbon ages and 137Cs activity). This dataset allows distinguishing between the different sources (rivers or hemipelagic sediment) of the turbidites deposited in the deep basin of Lake Geneva. However, no clear distinction between the various trigger processes (mass failures or floods) could be made, thus flood deposits could not be clearly identified. From our results, we also conclude that the lack of turbidite deposits in the deep basin between the 15th and 18th century seems to be linked to a change in turbidite depocentre due to the Rhone River mouth shifting possibly triggered by human activity and not by any direct climate effect. This study demonstrates that a least two conditions are needed to perform an adequate paleohydrological interpretation based on turbidite records: (1) the holistic understanding of the basin sedimentary system and (2) the distinction of flood-induced turbidites from other types of turbidites (mass failures etc.).

    To assess and compare the diagnostic power for pulmonary embolism (PE) of Wells and revised Geneva scores in two independent cohorts (training and validation groups) of elderly adults hospitalized in a non-emergency department. Prospective clinical study, January 2011 to January 2013. Unit of Internal Medicine inpatients, University of Catania, Italy. Elderly adults (mean age 76 ± 12), presenting with dyspnea or chest pain and with high clinical probability of PE or D-dimer values greater than 500 ng/mL (N = 203), were enrolled and consecutively assigned to a training (n = 101) or a validation (n = 102) group. The clinical probability of PE was assessed using Wells and revised Geneva scores. Clinical examination, D-dimer test, and multidetector computed angiotomography were performed in all participants. The accuracy of the scores was assessed using receiver operating characteristic analyses. PE was confirmed in 46 participants (23%) (24 training group, 22 validation group). In the training group, the area under the receiver operating characteristic curve was 0.91 (95% confidence interval (CI) = 0.85-0.98) for the Wells score and 0.69 (95% CI = 0.56-0.82) for the revised Geneva score (P < .001). These results were confirmed in the validation group (P < .05). The positive (LR+) and negative likelihood ratios (LR-) (two indices combining sensitivity and specificity) of the Wells score were superior to those of the revised Geneva score in the training (LR+, 7.90 vs 1.34; LR-, 0.23 vs 0.66) and validation (LR+, 13.5 vs 1.46; LR-, 0.47 vs 0.54) groups. In high-risk elderly hospitalized adults, the Wells score is more accurate than the revised Geneva score for diagnosing PE. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

    Diagenesis of carbonate rocks is known to affect the petrophysical properties (porosity, permeability) of the host rock. Assessing the diagenetic history of the rock is thus essential when evaluating any reservoir exploitation project. The Canton of Geneva (Switzerland) is currently exploring the opportunities for geothermal energy exploitation in the Great Geneva Basin (GGB) sub-surface. In this context, a structural analysis of the basin (Clerc et al., 2016) associated with reservoir appraisal (Brentini et al., 2017) and rock-typing of reservoir bodies of potential interest were conducted (Rusillon et al., 2017). Other geothermal exploitation projects elsewhere (e.g. Bavaria, south Germany, Paris Basin, France) showed that dolomitized carbonate rocks have good reservoir properties and are suitable for geothermal energy production. The objectives of this work are to (1) describe and characterize the dolomitized bodies in the GGB and especially their diagenetic history and (2) quantify the reservoir properties of those bodies (porosity, permeability). Currently, our study focuses on the Upper Jurassic sedimentary bodies of the GGB. Field and well data show that the dolomitization is not ubiquitous in the GGB. Results from the petrographical analyses of the Kimmeridgian cores (Humilly-2) and of field analogues (Jura, Saleve and Vuache mountains) display complex diagenetic histories, dependent of the study sites. The paragenesis exhibits several stages of interparticular calcite cementation as well as different stages of dolomitization and/or dedolomitization. Those processes seem to follow constrained path of fluid migrations through burial, faulting or exhumation during the basin's history. These complex diagenetic histories affected the petrophysical and microstructural properties via porogenesis (conservation of initial porosity, moldic porosity) and/or poronecrosis events. The best reservoir properties appear to be recorded in patch reef and peri

    Full Text Available In response to the decrease of phosphorus concentrations in Lake Geneva (France and Switzerland, the mean percentage of individuals belonging to oligochaete species sensitive to low oxygen concentrations has increased in the profundal from 8% in 1983 to 31% in 2003. But these species decreased anew from 17% in 1999 to 2% in 2009 in the western basin of Lake Geneva (the Small Lake. This shallow basin is more exposed to the effects of warming observed since 1989 than the rest of the lake. To demonstrate these effects, the response of the main species to the increase of organic sedimentation was analysed in the gradient of fine sediment accumulation (FSA, observed in 1999 in the Small Lake. As expected, the abundance of four species classified as sensitive to low oxygen concentrations - Stylodrilus lemani, Embolocephalus velutinus, Bichaeta sanguinea, Paracladopelma nigritula gr. - decreased with the increase of FSA whereas the inverse relationship was observed for four species classified as tolerant Potamothrix vejdovskyi or very tolerant P. hammoniensis, P. heuscheri, and Tubifex tubifex. In contrast, the abundance of three species was not correlated with FSA: Stylodrilus heringianus and Micropsectra contracta both classified as sensitive, Limnodrilus hoffmeisteri as tolerant. The first component of a principal component analysis, based on the mean abundance per transect of the above species, was correlated with FSA. The second component could reflect the long-term increase of water temperature which has been advantageous for Limnodrilus and Micropsectra but disadvantageous for the sensitive oligochaete species less adapted to warm water lakes. Indeed, the abundance of the sensitive oligochaete species and of P. vejdovskyi has decreased from 1994 to 2009 in the Small Lake whereas the abundance of Limnodrilus has increased. Micropsectra and Paracladopelma became more abundant than sensitive oligochaete species. In addition to the effects of

    This research first focuses on the spatial and temporal patterns of heavy metals from contrasting environments (highly polluted to deepwater sites) of Lake Geneva. The mercury (Hg) and lead (Pb) records from two deepwater sites show that the heavy metal variations before the industrial period are primarily linked to natural weathering input of trace elements. By opposition, the discharge of industrial treated wastewaters into Vidy Bay of Lake Geneva during the second part of the 20th century, involved the sedimentation of highly metal-contaminated sediments in the area surrounding the WWTP outlet pipe discharge. Eventually, a new Pb isotope record of sediments from Lake Lucerne identifies the long-term increasing anthropogenic lead pollution after ca. 1500, probably due to the development of metallurgical activities during the High Middle Ages. These data furthermore allows to compare the recent anthropogenic sources of water pollution from three of the largest freshwater lakes of Western Europe (lakes Geneva, Lucerne, and Constance). High increases in Pb and Hg highlight the regional impact of industrial pollution after ca. 1750-1850, and the decrease of metal pollution in the 1980s due to the effects of remediation strategies such as the implementation of wastewater treatment plants (WWTPs). However, at all the studied sites, the recent metal concentrations remain higher than pre-industrial levels. Moreover, the local scale pollution data reveal two highly contaminated sites (>100 μg Pb/g dry weight sediment) by industrial activities, during the late-19th and early-20th centuries (Lake Lucerne) and during the second part of the 20th century (Vidy Bay of Lake Geneva). Overall, the regional scale pollution history inferred from the three large and deep perialpine lakes points out at the pollution of water systems by heavy metals during the last two centuries due to the discharge of industrial effluents.

    This study aims to understand how the health dimension is integrated into four impact assessment tools used in Geneva, Switzerland: environmental impact assessment (EIA), strategic environmental assessment (SEA), sustainability assessment (SA) and health impact assessment (HIA). We have chosen as a case study greenhouse gas (GHG) emissions reduction policies chosen by the city of Geneva. The methodological approach consists in analysing EIA, SEA, SA and HIA conducted on three projects in three topic areas: urban planning, heating and transportation. These projects are: a complex urbanisation plan in an urban neighbourhood in Geneva (the Gare des Eaux-Vives project), a sustainable transportation plan for a central district in Geneva (the St-Gervais transportation project) and a strategy to encourage the City's employees to use sustainable transport for local business travel. The results show some shortcomings in the consideration of health in SEA, EIA and SA. This work highlights a narrow vision of health in SEA and EIA, limiting itself to a review of the effects of projects on the determinants of the physical environment as required by the legislation relating to these tools. EIA does not require the integration of the health dimension. As for SA, our research found that health is treated much more superficially than in HIA and primarily through the analysis of 'health and safety' criteria. It appears from this work that HIA is the tool which provides the most elaborate assessment, compared to SA, SEA or EIA, of the consequences for health of the GHG reduction policies chosen by the local decision-makers of a city. However, our study suggests that the HIA community should identify the situations in which HIA should be carried out and in which cases it is better to include health issues within an integrated analysis.

    Physicians working with multicultural populations need to know how to elicit the patient's understanding of the illness; determine the patient's sociocultural context and identify any issues that might affect care; communicate effectively across patient-provider social and cultural differences; and collaborate effectively with an interpreter. Skills self-assessment can contribute to identifying training needs and monitoring skills development in these areas. As part of a larger study exploring the knowledge, attitudes and practices of Geneva physicians and medical students regarding the care of immigrant patients, we asked respondents to self-rate their ability to perform a range of common yet challenging intercultural communication tasks. Overall, respondents rated themselves less competent at intercultural tasks than at basic medical skills and less competent at specific intercultural communication skills than at general intercultural skills. Qualified doctors (as opposed to students), those with greater interest in caring for immigrants, and those who rarely encountered difficulties with immigrants rated themselves significantly more competent for all clinical tasks. Having a higher percentage of immigrant patients and previous cultural competence training predicted greater self-rated intercultural communication skills. Our self-assessment results suggest that students and physicians should be provided with the opportunity to practice intercultural skills with immigrant patients as part of their cultural competence training. To strengthen the validity of self-assessment measures, they should ideally be combined with more objective methods to assess actual skills.

Lepton EDMs therefore offer an excellent opportunity to discover unambiguous evidence for new CP-violating phases, as called for by the baryon-antibaryon asymmetry of the universe. The muon EDM is one of the least constrained fundamental properties in elementary particle physics. We propose to utilize the large available flux of polarized muons at PSI to search for a muon EDM ...

    Mathilde Fontanet and Odette Habiyakare. (@Photo Bianco)This book is the result of a meeting of two women. In 1994 Odette lived through the genocide in Rwanda, in which she lost most of her family. She wanted to record her account of the events and asked Mathilde to set them down in writing for her. Odette tells us not only of persecution, terror and atrocities but also of the happy days before the massacres, of the warmth of family life, of celebrations under the stars, of herds of cattle in the hills and of her well-regimented life at boarding school in Kigali, where the girls all wore well-pressed blouses and had names straight out of Balzac. Mathilde listens, reacts and responds with an account of her own contrasting memories of life in Geneva. Whether she is telling us about the non-religious Christmases of her youth, a child’s feelings of humiliation, encounters that have enriched her life or the experience of grieving, she s...

    A World Health Organization (WHO) consultation on guidelines for National Regulatory Authorities (NRAs) and vaccine manufacturers on clinical evaluation of vaccines was held from 17 to 18 July 2014, to review key scientific challenges that regulators have been facing since the establishment of the WHO Guidelines on Clinical Evaluation of Vaccines. The guidelines, adopted by the WHO Expert Committee on Biological Standardization (ECBS) in 2001, have served as the basis for setting or updating national requirements for the evaluation and licensing of a broad range of vaccines as well as for WHO vaccine prequalification. Regulators from Australia, Brazil, China, Canada, Germany, India, Republic of Korea, South Africa, United States of America and the United Kingdom were represented. The International Federation for Pharmaceutical Manufacturers' Association (IFPMA) and the Developing Country Vaccine Manufacturers' Network (DCVMN) provided industry representation. The consultation concluded that the guidelines should be revised to address issues that were raised in the context of vaccines that were the subject of clinical development in the past decade. Although the current guidelines have served well over time, it was recognized that an update would further increase their utility and would help regulators, manufacturers, vaccine developers and academia to respond to the challenging questions regarding the safety, immunogenicity, efficacy and effectiveness of vaccines intended for global use. A summary of the main outcomes of the consultation and proposals for the next steps regarding the guidelines and beyond are provided in this report. Copyright © 2015 The Authors.

    1996-01-01

    This paper describes the four research monographs on emigration that were presented at the December 1995 Regional Workshop in the Arab Region. The workshop was an exchange of views and discussion of policy implications of emigration. Monographs were presented by Dr. Mayar Farrag on emigration in Egypt, Professor Nadji Safir on migration in the Maghreb, Dr. Setenay Shami on emigration dynamics in Jordan, and Dr. Lynn Evans on behalf of Dr. Ivy Papps on migration in Gulf Cooperation Council (GCC) countries. Dr. Farrag identified three periods of migration. During the mid-1960s to the mid-1970s, migrants were officially encouraged by Egypt to fill education positions. During the 1970s, many migrants left for the oil-producing countries on a temporary basis. Since the mid-1980s, the influences on Egyptian migration have been the economic recession and oil prices in the Gulf states, the completion of infrastructure projects in most Gulf states, and the replacement of foreign labor with nationals. Dr. Farrag recommended improving the migrants' skills in English and technology in order to maintain a dominant flow of temporary migrants to the Gulf region. Professor Safir reported that persons from the Maghreb region (Tunisia, Algeria, and Morocco) migrated to France before independence and subsequently to West Germany and the Benelux countries. Algeria had the highest migration potential, and Morocco had the highest migration. Morocco had established networks in destination countries, high population growth rates, and high unemployment. Maghreb countries are receiving migrants from the south. Professor Safir recommended regional integration. Dr. Shami separated step migration from stepwise migration, which complicates push-pull theories. Dr. Papps argued that use of foreign labor may not be the best option for development, and that sending countries should be more aware of skill needs in GCC countries.

    This research first focuses on the spatial and temporal patterns of heavy metals from contrasting environments (highly polluted to deepwater sites) of Lake Geneva. The mercury (Hg) and lead (Pb) records from two deepwater sites show that the heavy metal variations before the industrial period are primarily linked to natural weathering input of trace elements. By opposition, the discharge of industrial treated wastewaters into Vidy Bay of Lake Geneva during the second part of the 20th century, involved the sedimentation of highly metal-contaminated sediments in the area surrounding the WWTP outlet pipe discharge. Eventually, a new Pb isotope record of sediments from Lake Lucerne identifies the long-term increasing anthropogenic lead pollution after ca. 1500, probably due to the development of metallurgical activities during the High Middle Ages. These data furthermore allows to compare the recent anthropogenic sources of water pollution from three of the largest freshwater lakes of Western Europe (lakes Geneva, Lucerne, and Constance). High increases in Pb and Hg highlight the regional impact of industrial pollution after ca. 1750-1850, and the decrease of metal pollution in the 1980s due to the effects of remediation strategies such as the implementation of wastewater treatment plants (WWTPs). However, at all the studied sites, the recent metal concentrations remain higher than pre-industrial levels. Moreover, the local scale pollution data reveal two highly contaminated sites (> 100 {mu}g Pb/g dry weight sediment) by industrial activities, during the late-19th and early-20th centuries (Lake Lucerne) and during the second part of the 20th century (Vidy Bay of Lake Geneva). Overall, the regional scale pollution history inferred from the three large and deep perialpine lakes points out at the pollution of water systems by heavy metals during the last two centuries due to the discharge of industrial effluents.

This might have contributed to the decision of medical schools throughout the world to adopt community-based learning activities. The community-based learning approach has been promoted and supported by the World Health Organization and has emerged as an efficient learning strategy. The aim of the present paper is to describe the characteristics of a community immersion clerkship for third-year undergraduate medical students, its evolution over 15 years, and an evaluation of its outcomes. Methods: A review of the literature and consensus meetings with a multidisciplinary group of health professionals were used to define learning objectives and an educational approach when developing the program. Evaluation of the program addressed students' perception, achievement of learning objectives, interactions between students and the community, and educational innovations over the years. Results: The program and the main learning objectives were defined by consensus meetings among teaching staff and community health workers, which strengthened the community immersion clerkship. Satisfaction, as monitored by a self-administered questionnaire in successive cohorts of students, showed a mean of 4.4 on a five-point scale. Students also mentioned community immersion clerkship as a unique community experience. The learning objectives were reached by a

    Public transport is the most effective mode of transport in the era of climate change and oil depletion. It can address climate change issues by reducing urban greenhouse gas emission and oil consumption while at the same time improving mobility. However, many public transport networks are not effective and instead create high operating costs with low frequencies and occupancy. Melbourne is one example of a metropolitan area that faces this problem. Even though the city has well-integrated train and tram networks, Melbourne’s bus network still needs to be improved. This study used network planning approach to redesign the bus network in the City of Glen Eira, a Local Government Area (LGA) in the southeastern part of Metropolitan Melbourne. The study area is the area between Gardenvale North and Oakleigh Station, as well as between Caulfield and Patterson Stations. This area needs network improvement mainly because of the meandering bus routes that run within it. This study aims to provide recommendations for improving the performance of bus services by reducing meandering routes, improving transfer point design and implementing coordinated timetables. The recommendations were formulated based on a ‘ready-made’ concept to increase bus occupancy. This approach can be implemented in other cities with similar problems and characteristics including those in Indonesia.

    International migration poses important challenges to European health care systems. The development of "migrant friendly hospitals" has been identified as a priority in both Europe and Switzerland. A multi-pronged initiative was developed at Geneva University Hospitals (HUG) to improve staff knowledge and use of existing "migrant friendly" resources. A self-administered questionnaire was sent pre and post-intervention to random samples of 4 major professional groups with direct patient contact at the HUG. The questionnaire assessed staff knowledge, attitudes and reported practices regarding the care of migrant patients. Overall response rate was 51% (N = 1460) in 2010 but only 19% (N = 761) in 2013 owing to an institutionally imposed change in survey method. Despite these difficulties, and after adjusting for sample differences, we found that respondents in 2013 were significantly more likely to have received training in how to organize an appointment with an interpreter, how to work with an interpreter and about health and social services available for migrant patients. Respondents were also significantly more likely to have used several Migrant Friendly structures at the HUG. Use of, preference for and perceived skill at working with professional interpreters all improved, and respondents were both more likely to be encouraged by their supervisors to use professional interpreters, and less likely to be encouraged to look for alternative solutions for communicating with non francophone patients. Finally, 2013 respondents encountered fewer difficulties caring for migrant patients, although lack of time and language barriers continued to be the most important sources of difficulty. Our results suggest that an institution-wide information campaign may contribute to increased awareness and use of migrant friendly resources by clinical staff. Hospital commitment and financing, along with inter-departmental participation in all activities were important in creating and

    Full Text Available Background: In most cases, the work of medical doctors, be they general practitioners or specialists, involves some dimension of health promotion (HP. There is thus ample justification for increasing the awareness of medical students vis-à-vis HP and its relevance for their future practice.Methods: In the context of a major curriculum reform (problem-based learning [PBL] at the Faculty of Medicine of the University of Geneva in the mid-1990s, several steps were taken to strengthen HP throughout the curriculum and include HP in its key domains as defined by the Ottawa Charter (OC.Results: First, the political dimension of HP was developed in a series of first- and fifth-year lectures and third-year workshops; second, community action was strengthened through a third year one-month community immersion program; third, the development of personal skills was integrated into second- and third-year PBL cases and into fourth-and fifth-year learning activities in clinical settings as well as second- and third-year HP electives; in terms of reorienting health services, the chosen approach included the development of a HP-specific track in the context of a Certificate of Advanced Studies (CAS in Community Health and a Master of Advanced Studies(MAS in Public Health. Furthermore, a supportive intra-university environment was created through a collaborative convention with Health Promotion Switzerland, which is in charge of coordinating HP in Switzerland.Conclusion: In our view, HP teaching for medical students seems all the more relevant given that future medical doctors will have to take care of an increasing number of patients likely to develop chronic non-communicable diseases.

    The essence of our work at CERG-C (www.unige.ch/hazards) is to train participants, coming from around the world and with various academic and professional backgrounds, to incorporate risk science related to natural hazards into everyday life in an attempt to reduce losses in disasters. Principle components include training participants to assess risk, from hazard to vulnerability, and communicate effectively with government agencies, media, public and private sectors before, during and after natural disasters. Nine weeks of training involve 5 weeks of lectures in Geneva (in English), 2 weeks of field immersion and 2 weeks of exams. Participant experience culminates in completion of an independent research memoir carried out over an additional 6 months. The course is divided into five modules: the risk management module, which includes humanities and social sciences and brings together a multi-disciplinary team of experts to provide participants with tools they can use to assess hazard, vulnerability and risk and provide solutions to risk management issues in their own countries; and four thematic risk modules, i.e., volcanic risk, seismic risk, landslide risk, and flood and climate related risk. As part of the volcanic risk module we also carry out a role-play exercise at the elementary school in Vulcano Island, Italy in collaboration with the Italian Civil Protection with the double goal of sensitizing the CERG-C participants on the importance of training hazard and risk at an early stage in people's life as well as to raise awareness in the local population on topics such as the evaluation of volcanic hazards and risk, management of a volcanic crisis, and the importance of the collaboration between citizens and official institutions, such as the Civil Protection.

    Full Text Available Abstract Background The incidence of tuberculosis (TB in developed countries has decreased since the 1990s, reflecting worldwide efforts to identify and treat TB according to WHO recommendations. However TB remains an important public health problem in industrialized countries with a high proportion of cases occurring among subjects originating from high prevalence countries. The aim of this study was to describe clinical and social characteristics of patients with TB and their outcome in a low incidence area with a high immigration rate. Methods Four-year retrospective study based on a computerized database and subsequent review of medical records of all patients with TB followed at the outpatient section of the Division of Pulmonary Diseases, Geneva University Hospital, Switzerland. Results 252 patients (84% foreigners, 25% asylum seekers aged 38 ± 19 yrs were studied (11% co-infected with HIV. TB was intrapulmonary (TBP in 158 cases (63%, extrapulmonary (TBE in 137 (54%, and both in 43 cases (17%. TBP was smear (S+/culture (C+ in 59%, S-/C+ in 37%, S-/C- in 4%. Smoking was significantly associated with cavitary disease. Time from onset of symptoms to diagnosis was 2.1 ± 3.1 months. Initially, 10% were asymptomatic; 35% had no general symptoms. Despite systematic sputum analysis (induced or spontaneous, TBP was confirmed only by bronchoscopy in 38 subjects (24% of TBP. Side effects requiring changes in treatment occurred in 38 cases (11%. Treatment was completed in 210 (83% patients. In 42 cases, follow up was unsuccessful; causes were: failure (n = 2; 0.8%, defaulters (n = 8; 3%, transfer out (n = 28; 11% and death (n = 4; 1.6%. Relapse rate was 0.24 per 100 patient-years. Considering S+ TBP only, success rate was 87%. Conclusion TB in our area is predominantly a disease of young foreign-born subjects. Smoking appears as a possible risk factor for cavitary TBP. Time to diagnosis remains long. Compliance to treatment is satisfactory. Success

The sensitivity of the instrument is of the order of 10-7rad sqrtHz-1 with infrared light stored in the Fabry-Perot. Measurements have been made with infrared laser light until 2004, and with green light during 2005. With a residual pressure less than 10-7 mbar the apparatus gives both ellipticity and rotation signals at the 10-7 rad level. These signals can be...

The main goal of this experiment was to test the reliability of the quantum layer over a long period of time in a production environment. A key management layer has been developed to manage the key between the three nodes of the network. This QKD-secure network was utilized by end-users through an application layer. (paper)

  11. Remarkable change in age-specific breast cancer incidence in the Swiss canton of Geneva and its possible relation with the use of hormone replacement therapy

    2006-01-01

    This article aims to explain the reasons for the remarkable change in age of breast cancer occurrence in the Swiss canton of Geneva. We used population-based data from the Geneva cancer registry, which collects information on method of detection, stage and tumour characteristics since 1975. For patients diagnosed between 1997–2003, we obtained additional information on use of hormone replacement therapy from a large prospective study on breast cancer. Using generalized log linear regression analysis, we compared age-specific incidence rates with respect to period, stage, oestrogen receptor status, method of detection and use of hormone replacement therapy. In the periods 1975–1979 and 1985–1989, breast cancer risk increased with age, showing the highest incidence rates among women aged ≥ 85 years. From 1997, the age-specific incidence curve changed completely (p < 0.0001), showing an incidence peak at 60–64 years and a reduced incidence among elderly women. This incidence peak concerned mainly early stage and oestrogen positive cancers and was exclusively observed among women who ever used hormone replacement therapy, regardless whether the tumour was screen-detected or not. The increasing prevalence of hormone replacement therapy use during the 1990s could explain the important change in age-specific breast cancer incidence, not only by increasing breast cancer risk, but also by revealing breast cancer at an earlier age

    1993-01-01

    The Geneva Industries Site is an abandoned refinery in Houston, Texas, that manufactured polychlorinated biphenyls (PCBs). Although there is evidence of past exposure to site contaminants, the site currently poses no apparent public health hazard. The contaminants to which persons may have been exposed in the past include polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The lack of historical ambient air data from the time when the site was active prevents us from evaluating the potential for adverse health effects from inhalation exposure. Although fish and crawfish taken from the local drainageways were contaminated with PCBs, it is unlikely that humans would have been exposed to these species through the food chain. The groundwater under the site is contaminated. Although the contaminated water is not currently being used for human consumption, there is a potential for exposure to contaminated groundwater in the future. Planned groundwater remedial actions should eliminate this threat

    Air pollution is one of the leading environmental problems of out times that could eventually change the living conditions of human beings and the ecosystems on the whole planet. Therefore, international forums have been created to discuss environmental policies aimed at the control of pollutant emissions and the protection of ecosystems and human health. the fundamental purpose is to take common actions that go beyond political borders, since in many cases the emissions of pollutants affect ecosystems far from the emission source. These were the objectives leading to the creation of the Geneva Convention on Long-Range Transboundary Air Pollution, of the Economic commission for Europe-United Nations (UNECE). (Author) 12 refs.

    The occurrence and removal of 58 pharmaceuticals, endocrine disruptors, corrosion inhibitors, biocides, and pesticides, were assessed in the wastewater treatment plant (WWTP) of the city of Lausanne, Switzerland, as well as in the effluent-receiving water body, the Vidy Bay of Lake Geneva. An analytical screening method to simultaneously measure all of the 58 micropollutants was developed based on ultra performance liquid chromatography coupled to a tandem mass spectrometer (UPLC-MS/MS). The selection of pharmaceuticals was primarily based on a prioritization study, which designated them as environmentally relevant for the Lake Geneva region. Except for the endocrine disruptor 17alpha-ethinylestradiol, all substances were detected in 24-h composite samples of wastewater entering the WWTP or in the treated effluent. Of these compounds, 40% were also detected in raw drinking water, pumped from the lake 3 km downstream of the WWTP. The contributions of dilution and degradation to micropollutant elimination between the WWTP outlet and the raw drinking water intake were established in different model scenarios using hypothetical residence times of the wastewater in Vidy Bay of 1, 4, or 90 d. Concentration decrease due to processes other than dilution was observed for diclofenac, beta-blockers, several antibiotics, corrosion inhibitors, and pesticides. Measured environmental concentrations (MECs) of pharmaceuticals were compared to the predicted environmental concentrations (PECs) determined in the prioritization study and agreed within one order of magnitude, but MECs were typically greater than the corresponding PECs. Predicted no-effect concentrations of the analgesic paracetamol, and the two antibiotics ciprofloxacin and sulfamethoxazole, were exceeded in raw drinking water samples and therefore present a potential risk to the ecosystem.

    The ATLAS-MPX Network is a network of 15 Medipix2-based detector devices, installed in various positions in the ATLAS detector at CERN, Geneva. The aim of the network is to perform a real-time measurement of the spectral characteristics and the composition of radiation inside the ATLAS detector during its operation. The remote control system of ATLAS-MPX controls and configures all the devices from one place, via a web interface, accessible from different operating systems. The Data Visualization application, also with a web interface, has been developed in order to present measured data to the scientific community. It allows to browse through recorded frames from all devices and to search for specific frames by date and time. Charts containing the number of different types of tracks in each frame as a function of time may be rendered from the database.

    The CERN high energy particle physics facility at Geneva, Switzerland will incorporate a wide range of COTS industrial control systems within its next generation particle collider, the LHC. In particular, the Internet will be used to facilitate the remote access for accelerator and particle physicists and system experts based at several hundred locations around the globe. The integration of Industrial Ethernet and COTS PLCs within the LHC program focuses extreme attention on the industrial network cyber-security requirement. CERN's response has been to conduct operational research on the security resilience of networked industrial devices. As test team lead Stefan Lüders reports here, industrial networked devices put through the organisation's test procedures have generally shown up unexpected vulnerabilities.

    Since 1945, the reason for humanitarian crises and the way in which the world responds to them has dramatically changed every 10 to 15 years or less. Planning, response, and recovery for these tragic events have often been ad hoc, inconsistent, and insufficient, largely because of the complexity of global humanitarian demands and their corresponding response system capabilities. This historical perspective chronicles the transformation of war and armed conflicts from the Cold War to today, emphasizing the impact these events have had on humanitarian professionals and their struggle to adapt to increasing humanitarian, operational, and political challenges. An unprecedented independent United Nations-World Health Organization decision in the Battle for Mosul in Iraq to deploy to combat zones emergency medical teams unprepared in the skills of decades-tested war and armed conflict preparation and response afforded to health care providers and dictated by International Humanitarian Law and Geneva Convention protections has abruptly challenged future decision-making and deployments.

    While broad agreement now exists among sponsors of HIV prevention trials that antiretroviral therapy (ART) and a clinical care package should be provided to those who become infected during the conduct of a trial, certain practical issues remain unresolved, including Who should pay for ART? How long should ART be provided for? Does treatment extend outside of ART? What else should be included in the standard of care package and who should pay for it? Who should provide treatment and care? This report summarizes the discussions from a consultation held in Geneva (17-18 July 2003) organized by the World Health Organization (WHO) and the joint United Nations Programme on HIV/AIDS (UNAIDS). The group discussed issues related to the various types of HIV prevention trials covered - vaccines, microbicides, behavioural - the ethics and legal rational for providing treatment and care as well as relevant economic issues and developments around scale-up of treatment and care in middle- and lower-income countries. Also discussed were policies of certain research agencies, countries and international funding agencies. The implementation of the conclusions which came out of these discussions on the treatment and care for people who become infected during HIV prevention trials requires the active participation of members of the research community, funders of research, local and national governments and industry as well as the individuals or communities participating in the trials.

    This paper describes the six research monographs that were presented at the Emigration Dynamic Workshops in South Asia in September 1996. Research reports were presented by Associate Professor Nasra Shah on an overview of emigration dynamics, Dr. Godfrey Gunatilleke on the role of networks and community structures in migration from Sri Lanka, Dr. Raisul Awal Mahmood on illegal migration from Bangladesh to Singapore, Kuala Lumpur, Bangkok, and Delhi due to desperate poverty, Dr. Farooq-i-Azam on high and low labor-sending migration districts in Pakistan, Dr. Mahendra K. Premi on the impact of internal Indian migration on international migration, and Dr. P.R. Gopinathan Nair on emigration from Kerala, India, to the Middle East. Representatives of South Asian governments discussed the implications of the research findings. Pakistan's representative urged cooperation and joint strategies among labor-sending countries. He cautioned that income and remittance estimates were unstable and unrealistic for inclusion in economic development plans. The Indian representative noted that, although Indian emigration is low, it is highly visible in the press. He agreed with the suggestion for greater cooperation between sending countries. The Bangladesh representative stated that the country needed to locate new markets for Bangladeshi emigrants, to guarantee the rights of emigrant workers, and to prevent trafficking in illegal migrant workers. Three major topics were discussed in the workshop session on the implementation of programs based on research findings. Workshop participants recommended updated information on migration trends, updated information on labor markets in receiving countries, formal and regular policy dialogue between sending countries, and promotion of continuing research by the International Organization on Migration.

    In 2007 the "Crisp Report" on international partnerships increased interest in Northern countries on the way their links with Southern partners operated. Since its establishment in 2007 the Division of Tropical and Humanitarian Medicine at the Geneva University Hospitals has developed a variety of partnerships. Frameworks to assess these partnerships are needed and recent attention in the field of public management on collaborative governance may provide a useful approach for analyzing international collaborations. Projects of the Division of Tropical and Humanitarian Medicine were analyzed by collaborators within the Division using the model proposed by Emerson and colleagues for collaborative governance, which comprises different components that assess the collaborative process. International projects within the Division of Tropical and Humanitarian Medicine can be divided into four categories: Human resource development; Humanitarian response; Neglected Tropical Diseases and Noncommunicable diseases. For each of these projects there was a clear leader from the Division of Tropical and Humanitarian Medicine as well as a local counterpart. These individuals were seen as leaders both due to their role in establishing the collaboration as well as their technical expertise. Across these projects the actual partners vary greatly. This diversity means a wide range of contributions to the collaboration, but also complexity in managing different interests. A common definition of the collaborative aims in each of the projects is both a formal and informal process. Legal, financial and administrative aspects of the collaboration are the formal elements. These can be a challenge based on different administrative requirements. Friendship is part of the informal aspects and helps contribute to a relationship that is not exclusively professional. Using collaborative governance allows the complexity of managing partnerships to be presented. The framework used highlights the

    Declarative Networking is a programming methodology that enables developers to concisely specify network protocols and services, which are directly compiled to a dataflow framework that executes the specifications. Declarative networking proposes the use of a declarative query language for specifying and implementing network protocols, and employs a dataflow framework at runtime for communication and maintenance of network state. The primary goal of declarative networking is to greatly simplify the process of specifying, implementing, deploying and evolving a network design. In addition, decla

  18. User-based representation of time-resolved multimodal public transportation networks.

    2016-07-01

    Multimodal transportation systems, with several coexisting services like bus, tram and metro, can be represented as time-resolved multilayer networks where the different transportation modes connecting the same set of nodes are associated with distinct network layers. Their quantitative description became possible recently due to openly accessible datasets describing the geo-localized transportation dynamics of large urban areas. Advancements call for novel analytics, which combines earlier established methods and exploits the inherent complexity of the data. Here, we provide a novel user-based representation of public transportation systems, which combines representations, accounting for the presence of multiple lines and reducing the effect of spatial embeddedness, while considering the total travel time, its variability across the schedule, and taking into account the number of transfers necessary. After the adjustment of earlier techniques to the novel representation framework, we analyse the public transportation systems of several French municipal areas and identify hidden patterns of privileged connections. Furthermore, we study their efficiency as compared to the commuting flow. The proposed representation could help to enhance resilience of local transportation systems to provide better design policies for future developments.

    The drinking water supply for the Geneva area comes partly (80%) from the lake Geneva and partly (20%) from a large transboundary aquifer called Genevois aquifer. During the 70's, over pumping lowered the groundwater level by more than 7m. Artificial recharge has been carried out from the Arve river into the Genevois aquifer in order to maintain the groundwater level and enable water resources management. Located near the Arve river, this artificial recharge plant started its activity in 1980. For the last almost 30 years the artificial recharge system of Geneva has brought over 230 hm{sup 3} of treated water into the Genevois aquifer. The impacts of the recharge on the Genevois aquifer and on the aquifer management are described in this paper. (Author) 20 refs.

    We define a measure of network cohesion and show how it arises naturally in a broad class of dynamic models of endogenous perpetual growth with network externalities. Via a standard growth model, we show why network cohesion is crucial for conditional convergence and explain that as cohesion increases, convergence is faster. We prove properties of network cohesion and define a network aggregator that preserves network cohesion.

    Prediction and control of the dynamics of complex networks is a central problem in network science. Structural and dynamical similarities of different real networks suggest that some universal laws might accurately describe the dynamics of these networks, albeit the nature and common origin of such laws remain elusive. Here we show that the causal network representing the large-scale structure of spacetime in our accelerating universe is a power-law graph with strong clustering, similar to many complex networks such as the Internet, social, or biological networks. We prove that this structural similarity is a consequence of the asymptotic equivalence between the large-scale growth dynamics of complex networks and causal networks. This equivalence suggests that unexpectedly similar laws govern the dynamics of complex networks and spacetime in the universe, with implications to network science and cosmology.

    2006-01-01

    Purpose of review: The enthusiasm generated by the results of the Edmonton protocol of islet transplantation is inciting a great number of institutions to start such programs. However, the procedure of islet isolation and purification is costly, complex and technically challenging. In order to share costs and to avoid facing the steep learning curve of the procedure, many centers interested in islet transplantation have looked into collaborating with experienced groups serving as core islet isolation facilities. Recent findings: The proof of principle that remote islet processing and shipment could be successfully implemented with obtainng the Portland/Minneapolis, Huddinge/Giessen and Houston/Miami partnerships. Moreover, in order to increase both the donor pool and the number of patients gaining access to islet transplantation, multicenter networks, such as the Swiss-French GRAGIL consortium and the 4-country Nordic Network in Scandinavia have been built. The GRAGIL group has been fully operational since 1999, allowing the transplantation of 27 islet preparations processed in Geneva, Switzerland into 20 recipients in France over the course of 4.5 years. Organizational issues in the design of such networks are discussed based on the example of the GRAGIL experience. Summary: The feasibility and the efficiency of islet transplantation in multicenter networks have been demonstrated. This strategy allows to increase the donor pool and the accessibility to islet transplantation in an extended population area. (authors)

    The Geneva freshwater lens is an isolated flow system within the upper Floridan aquifer surrounded and underlain by brackish water. The lens is sustained entirely by recharge from a surficial aquifer and sits atop a regional flow system which discharges around the fringes of the lens along the St. Johns River. Continual development of groundwater supply in the Geneva area has raised the concern of how much additional pumping can be allowed from various sites within the lens without adversely impacting water quality by inducing the invasion or upconing of salty water. A numerical modeling study was conducted to address these water management issues. A density-dependent, finite-element flow and transport code, DSTRAM, was used for cross-sectional and three-dimensional (3-D) analyses of the Geneva lens system. The model incorporates an enhanced upstream weighted technique for the transport equation, improved Picard iterations over the nonlinearities, and robust preconditioned conjugate gradient (PCG) and ORTHOMIN techniques for solving the matrix equations. A steady-state model calibration was performed for existing conditions at the site. The cross-sectional (2-D) analysis was inadequate in accurately representing the system, since the 3-D effects were considerable. However, 2-D cross-sectional simulations are useful for preliminary assessments of certain scenarios, and for guidance in developing the 3-D model. A comprehensive sensitivity analysis was performed on a number of key parameters. Natural groundwater discharge rates along the St. Johns River seem to be the most critical unknown and require better estimates for increased confidence in the conceptual model. Transient pumping scenarios were imposed on this system to observe the response of the lens and to determine well breakthrough for chlorides, if any. Pumping rates and distribution of pumping were significant factors in determining the quality of the water. Upconing of saline water contributes to high

  6. Temporal networks

    CERN Document Server

    Saramäki, Jari

    2013-01-01

    The concept of temporal networks is an extension of complex networks as a modeling framework to include information on when interactions between nodes happen. Many studies of the last decade examine how the static network structure affect dynamic systems on the network. In this traditional approach  the temporal aspects are pre-encoded in the dynamic system model. Temporal-network methods, on the other hand, lift the temporal information from the level of system dynamics to the mathematical representation of the contact network itself. This framework becomes particularly useful for cases where there is a lot of structure and heterogeneity both in the timings of interaction events and the network topology. The advantage compared to common static network approaches is the ability to design more accurate models in order to explain and predict large-scale dynamic phenomena (such as, e.g., epidemic outbreaks and other spreading phenomena). On the other hand, temporal network methods are mathematically and concept...

  7. Interconnected networks

    CERN Document Server

    2016-01-01

    This volume provides an introduction to and overview of the emerging field of interconnected networks which include multi layer or multiplex networks, as well as networks of networks. Such networks present structural and dynamical features quite different from those observed in isolated networks. The presence of links between different networks or layers of a network typically alters the way such interconnected networks behave – understanding the role of interconnecting links is therefore a crucial step towards a more accurate description of real-world systems. While examples of such dissimilar properties are becoming more abundant – for example regarding diffusion, robustness and competition – the root of such differences remains to be elucidated. Each chapter in this topical collection is self-contained and can be read on its own, thus making it also suitable as reference for experienced researchers wishing to focus on a particular topic.

  8. Interfacing a one-dimensional lake model with a single-column atmospheric model: 2. Thermal response of the deep Lake Geneva, Switzerland under a 2 × CO2 global climate change

    Science.gov (United States)

    Perroud, Marjorie; Goyette, StéPhane

    2012-06-01

    In the companion to the present paper, the one-dimensional k-ɛ lake model SIMSTRAT is coupled to a single-column atmospheric model, nicknamed FIZC, and an application of the coupled model to the deep Lake Geneva, Switzerland, is described. In this paper, the response of Lake Geneva to global warming caused by an increase in atmospheric carbon dioxide concentration (i.e., 2 × CO2) is investigated. Coupling the models allowed for feedbacks between the lake surface and the atmosphere and produced changes in atmospheric moisture and cloud cover that further modified the downward radiation fluxes. The time evolution of atmospheric variables as well as those of the lake's thermal profile could be reproduced realistically by devising a set of adjustable parameters. In a "control" 1 × CO2 climate experiment, the coupled FIZC-SIMSTRAT model demonstrated genuine skills in reproducing epilimnetic and hypolimnetic temperatures, with annual mean errors and standard deviations of 0.25°C ± 0.25°C and 0.3°C ± 0.15°C, respectively. Doubling the CO2 concentration induced an atmospheric warming that impacted the lake's thermal structure, increasing the stability of the water column and extending the stratified period by 3 weeks. Epilimnetic temperatures were seen to increase by 2.6°C to 4.2°C, while hypolimnion temperatures increased by 2.2°C. Climate change modified components of the surface energy budget through changes mainly in air temperature, moisture, and cloud cover. During summer, reduced cloud cover resulted in an increase in the annual net solar radiation budget. A larger water vapor deficit at the air-water interface induced a cooling effect in the lake.

  9. Network Ambivalence

    Directory of Open Access Journals (Sweden)

    Patrick Jagoda

    2015-08-01

    Full Text Available The language of networks now describes everything from the Internet to the economy to terrorist organizations. In distinction to a common view of networks as a universal, originary, or necessary form that promises to explain everything from neural structures to online traffic, this essay emphasizes the contingency of the network imaginary. Network form, in its role as our current cultural dominant, makes scarcely imaginable the possibility of an alternative or an outside uninflected by networks. If so many things and relationships are figured as networks, however, then what is not a network? If a network points towards particular logics and qualities of relation in our historical present, what others might we envision in the future? In  many ways, these questions are unanswerable from within the contemporary moment. Instead of seeking an avant-garde approach (to move beyond networks or opting out of networks (in some cases, to recover elements of pre-networked existence, this essay proposes a third orientation: one of ambivalence that operates as a mode of extreme presence. I propose the concept of "network aesthetics," which can be tracked across artistic media and cultural forms, as a model, style, and pedagogy for approaching interconnection in the twenty-first century. The following essay is excerpted from Network Ambivalence (Forthcoming from University of Chicago Press.

  18. Spatial networks

    Science.gov (United States)

    Barthélemy, Marc

    2011-02-01

    Complex systems are very often organized under the form of networks where nodes and edges are embedded in space. Transportation and mobility networks, Internet, mobile phone networks, power grids, social and contact networks, and neural networks, are all examples where space is relevant and where topology alone does not contain all the information. Characterizing and understanding the structure and the evolution of spatial networks is thus crucial for many different fields, ranging from urbanism to epidemiology. An important consequence of space on networks is that there is a cost associated with the length of edges which in turn has dramatic effects on the topological structure of these networks. We will thoroughly explain the current state of our understanding of how the spatial constraints affect the structure and properties of these networks. We will review the most recent empirical observations and the most important models of spatial networks. We will also discuss various processes which take place on these spatial networks, such as phase transitions, random walks, synchronization, navigation, resilience, and disease spread.

    2014-10-01

    Our dependence on networks - be they infrastructure, economic, social or others - leaves us prone to crises caused by the vulnerabilities of these networks. There is a great need to develop new methods to protect infrastructure networks and prevent cascade of failures (especially in cases of coupled networks). Terrorist attacks on transportation networks have traumatized modern societies. With a single blast, it has become possible to paralyze airline traffic, electric power supply, ground transportation or Internet communication. How, and at which cost can one restructure the network such that it will become more robust against malicious attacks? The gradual increase in attacks on the networks society depends on - Internet, mobile phone, transportation, air travel, banking, etc. - emphasize the need to develop new strategies to protect and defend these crucial networks of communication and infrastructure networks. One example is the threat of liquid explosives a few years ago, which completely shut down air travel for days, and has created extreme changes in regulations. Such threats and dangers warrant the need for new tools and strategies to defend critical infrastructure. In this paper we review recent advances in the theoretical understanding of the vulnerabilities of interdependent networks with and without spatial embedding, attack strategies and their affect on such networks of networks as well as recently developed strategies to optimize and repair failures caused by such attacks.

    In 2017 the ATLAS experiment implemented an ensemble of neural networks (NeuralRinger algorithm) dedicated to improving the performance of filtering events containing electrons in the high-input rate online environment of the Large Hadron Collider at CERN, Geneva. The ensemble employs a concept of calorimetry rings. The training procedure and final structure of the ensemble are used to minimize fluctuations from detector response, according to the particle energy and position of incidence. A detailed study was carried out to assess profile distortions in crucial offline quantities through the usage of statistical tests and residual analysis. These details and the online performance of this algorithm during the 2017 data-taking will be presented.

    Feng, Wu-chun

    2003-10-13

    This paper presents a case study of the 10-Gigabit Ethernet (10GbE) adapter from Intel(reg sign). Specifically, with appropriate optimizations to the configurations of the 10GbE adapter and TCP, we demonstrate that the 10GbE adapter can perform well in local-area, storage-area, system-area, and wide-area networks. For local-area, storage-area, and system-area networks in support of networks of workstations, network-attached storage, and clusters, respectively, we can achieve over 7-Gb/s end-to-end throughput and 12-{micro}s end-to-end latency between applications running on Linux-based PCs. For the wide-area network in support of grids, we broke the recently-set Internet2 Land Speed Record by 2.5 times by sustaining an end-to-end TCP/IP throughput of 2.38 Gb/s between Sunnyvale, California and Geneva, Switzerland (i.e., 10,037 kilometers) to move over a terabyte of data in less than an hour. Thus, the above results indicate that 10GbE may be a cost-effective solution across a multitude of computing environments.

    CERN Multimedia

    CERN. Geneva

    2012-01-01

    The Large Hadron Collider (LHC) is currently running at CERN in Geneva, Switzerland. Physicists are using LHC to recreate the conditions just after the Big Bang, by colliding two beams of particles and heavy ions head-on at very high energy. The project is expected to generate 27 TB of raw data per day, plus 10 TB of "event summary data". This data is sent out from CERN to eleven Tier 1 academic institutions in Europe, Asia, and North America using a multi-gigabits Optical Private Network (OPN), the LHCOPN. Network monitoring on such complex network architecture to ensure robust and reliable operation is of crucial importance. The chosen approach for monitoring the OPN is based on the perfSONAR MDM framework (http://perfsonar.geant.net), which is designed for multi-domain monitoring environments. perfSONAR (www.perfsonar.net) is an infrastructure for performance monitoring data exchange between networks, making it easier to solve performance problems occurring between network measurement points interconne...

    A great variety of systems in nature, society and technology-from the web of sexual contacts to the Internet, from the nervous system to power grids-can be modeled as graphs of vertices coupled by edges. The network structure, describing how the graph is wired, helps us understand, predict and optimize the behavior of dynamical systems. In many cases, however, the edges are not continuously active. As an example, in networks of communication via e-mail, text messages, or phone calls, edges represent sequences of instantaneous or practically instantaneous contacts. In some cases, edges are active for non-negligible periods of time: e.g., the proximity patterns of inpatients at hospitals can be represented by a graph where an edge between two individuals is on throughout the time they are at the same ward. Like network topology, the temporal structure of edge activations can affect dynamics of systems interacting through the network, from disease contagion on the network of patients to information diffusion over an e-mail network. In this review, we present the emergent field of temporal networks, and discuss methods for analyzing topological and temporal structure and models for elucidating their relation to the behavior of dynamical systems. In the light of traditional network theory, one can see this framework as moving the information of when things happen from the dynamical system on the network, to the network itself. Since fundamental properties, such as the transitivity of edges, do not necessarily hold in temporal networks, many of these methods need to be quite different from those for static networks. The study of temporal networks is very interdisciplinary in nature. Reflecting this, even the object of study has many names-temporal graphs, evolving graphs, time-varying graphs, time-aggregated graphs, time-stamped graphs, dynamic networks, dynamic graphs, dynamical graphs, and so on. This review covers different fields where temporal graphs are considered

    2015-01-01

    This paper examines the notion of network affordance within the context of network art. Building on Gibson's theory (Gibson, 1979) we understand affordance as the perceived and actual parameters of a thing. We expand on Gaver's affordance of predictability (Gaver, 1996) to include ecological...... and computational parameters of unpredictability. We illustrate the notion of unpredictability by considering four specific works that were included in a network art exhibiton, SPEED SHOW [2.0] Hong Kong. The paper discusses how the artworks are contingent upon the parameteric relations (Parisi, 2013......), of the network. We introduce network affordance as a dynamic framework that could articulate the experienced tension arising from the (visible) symbolic representation of computational processes and its hidden occurrences. We base our proposal on the experience of both organising the SPEED SHOW and participating...

    Full Text Available Viticultural practices influence both grape and wine quality. The influence of training systems on volatile composition was investigated for Albariño wine from Rías Baixas AOC in Northwest Spain. The odoriferous contribution of the compounds to the wine aroma was also studied. Volatile compounds belonging to ten groups (alcohols, C6-compounds, ethyl esters, acetates, terpenols, C13-norisoprenoids, volatile phenols, volatile fatty acids, lactones and carbonyl compounds were determined in Albariño wines from different training systems, Vertical Shoot-Positioned (VSP, Scott-Henry (SH, Geneva Double-Curtain (GDC, Arch-Cane (AC, and Parral (P during 2010 and 2011 vintages. Wines from GDC showed the highest total volatile composition with the highest concentrations of alcohols, ethyl esters, fatty acids, and lactones families. However, the highest levels of terpenes and C13-norisoprenoids were quantified in the SH system. A fruitier aroma was observed in Albariño wines from GDC when odor activity values were calculated.

    2007-01-01

    Evolving out-of-equilibrium networks have been under intense scrutiny recently. In many real-world settings the number of links added per new node is not constant but depends on the time at which the node is introduced in the system. This simple idea gives rise to the concept of accelerating networks, for which we review an existing definition and-after finding it somewhat constrictive-offer a new definition. The new definition provided here views network acceleration as a time dependent property of a given system as opposed to being a property of the specific algorithm applied to grow the network. The definition also covers both unweighted and weighted networks. As time-stamped network data becomes increasingly available, the proposed measures may be easily applied to such empirical datasets. As a simple case study we apply the concepts to study the evolution of three different instances of Wikipedia, namely, those in English, German, and Japanese, and find that the networks undergo different acceleration regimes in their evolution

    Full Text Available In this paper, we construct a new dynamic model for the Token Bucket (TB algorithm used in computer networks and use systems approach for its analysis. This model is then augmented by adding a dynamic model for a multiplexor at an access node where the TB exercises a policing function. In the model, traffic policing, multiplexing and network utilization are formally defined. Based on the model, we study such issues as (quality of service QoS, traffic sizing and network dimensioning. Also we propose an algorithm using feedback control to improve QoS and network utilization. Applying MPEG video traces as the input traffic to the model, we verify the usefulness and effectiveness of our model.

    In the last decade we have seen the emergence of a new inter-disciplinary field focusing on the understanding of networks which are dynamic, large, open, and have a structure sometimes called random-biased. The field of Complex Networks is helping us better understand many complex phenomena such as the spread of  deseases, protein interactions, social relationships, to name but a few. Studies in Complex Networks are gaining attention due to some major scientific breakthroughs proposed by network scientists helping us understand and model interactions contained in large datasets. In fact, if we could point to one event leading to the widespread use of complex network analysis is the availability of online databases. Theories of Random Graphs from Erdös and Rényi from the late 1950s led us to believe that most networks had random characteristics. The work on large online datasets told us otherwise. Starting with the work of Barabási and Albert as well as Watts and Strogatz in the late 1990s, we now know th...

    Physicists use large detectors to measure particles created in high-energy collisions at particle accelerators. These detectors typically produce signals indicating either where ionization occurs along the path of the particle, or where energy is deposited by the particle. The data produced by these signals is fed into pattern recognition programs to try to identify what particles were produced, and to measure the energy and direction of these particles. Ideally, there are many techniques used in this pattern recognition software. One technique, neural networks, is particularly suitable for identifying what type of particle caused by a set of energy deposits. Neural networks can derive meaning from complicated or imprecise data, extract patterns, and detect trends that are too complex to be noticed by either humans or other computer related processes. To assist in the advancement of this technology, Physicists use a tool kit to experiment with several neural network techniques. The goal of this research is interface a neural network tool kit into Java Analysis Studio (JAS3), an application that allows data to be analyzed from any experiment. As the final result, a physicist will have the ability to train, test, and implement a neural network with the desired output while using JAS3 to analyze the results or output. Before an implementation of a neural network can take place, a firm understanding of what a neural network is and how it works is beneficial. A neural network is an artificial representation of the human brain that tries to simulate the learning process [5]. It is also important to think of the word artificial in that definition as computer programs that use calculations during the learning process. In short, a neural network learns by representative examples. Perhaps the easiest way to describe the way neural networks learn is to explain how the human brain functions. The human brain contains billions of neural cells that are responsible for processing

    We consider normalized average edge betweenness of a network as a metric of network vulnerability. We suggest that normalized average edge betweenness together with is relative difference when certain number of nodes and/or edges are removed from the network is a measure of network vulnerability, called vulnerability index. Vulnerability index is calculated for four synthetic networks: Erdős-Rényi (ER) random networks, Barabási-Albert (BA) model of scale-free networks, Watts-Strogatz (WS) model of small-world networks, and geometric random networks. Real-world networks for which vulnerability index is calculated include: two human brain networks, three urban networks, one collaboration network, and two power grid networks. We find that WS model of small-world networks and biological networks (human brain networks) are the most robust networks among all networks studied in the paper.

    Since a couple of years, underground collectors with air circulation have been becoming increasingly popular as a simple means for preheating (at winter time) and cooling (at summer time) of outdoor air ahead of a ventilation system for well insulated buildings. This report considers underground collectors with water circulation used for similar purposes. They are connected to the ventilation system via an air/water heat exchanger. Starting from a case study - one-year detailed in-situ measurements and data analysis from an air-heated office building near Geneva, Switzerland - computerised simulations have been performed as a sensitivity analysis tool as well as to establish recommendations and sizing rules for planners, including cost considerations. In the case study it turned out that the water-circulated underground collector, which is installed right under the basement of this well insulated building, is in thermal contact with the basement. Its main function is to damp the daily temperature oscillation of the inlet ventilation air, bringing the expected thermal comfort improvement in the summer time. However, this underground collector is unable to collect seasonally stored heat from the ground. Hence, in the winter time the main preheating contribution arises from the series-connected heat-recovery unit from the exit air. Numerical simulations show that optimal sizing of underground collectors is essential, and that both the underground collector and the well insulated building as a physical system with thermal inertia have to be simultaneously considered in the optimization process. Optimization also has to include parasitic energy (electricity) needed by fans and pumps. As outdoor air inlet can never be flooded in the case of underground collectors with water circulation the sanitary risk encountered with air-circulated underground collectors does not exist for them. Initial investment cost for water-circulated underground collectors is higher than for a

    Full Text Available Background: In the literature the need for relevance in medical education and training has been stressed. In the last 40 years medical schools have been challenged to train doctors competent to respond to community health needs. In the mid-90s the University of Geneva Faculty of Medicine introduced an integrated medical curriculum. In this initiative a particular emphasis was put in introducing a 6-year longitudinal and multidisciplinary Community Health Program (CHP. Objectives: The aims of the present article are to describe the conception, elaboration and implementation of the CHP as well as its evolution over 15 years and the evaluation of its outcomes. Methods: The CHP was at its origin elaborated by a small group of highly motivated teachers and later on developed by a multi-disciplinary group of primary care physicians, epidemiologists, public health and bio-ethics specialists, occupational health professionals, lawyers and historians. Evaluation of the program outcomes included educational innovations, new developments of the curriculum and interactions between students and the community. Results: The CHP learning objectives and teaching modalities were defined by the multi-disciplinary group in consensus meetings which triggered a collaborative spirit among teachers and facilitated further developments. The evaluation procedures allowed the monitoring of students’ satisfaction which remained high over the years, students’ active participation which decreased over time and success at certifying exams which was globally as good as in basic life sciences. The evaluation also assessed outcomes such as educational innovations, new developments of the curriculum and interactions between students and the community. Conclusion: As suggested in the literature, our experience shows that the students’ direct exposure and practice in the community health environment is an effective training approach to broaden students’ education by

    Nuclear lamins are intermediate filament proteins that represent important structural components of metazoan nuclear envelopes (NEs). By combining proteomics and superresolution microscopy, we recently reported that both A- and B-type nuclear lamins form spatially distinct filament networks at the nuclear periphery of mouse fibroblasts. In particular, A-type lamins exhibit differential association with nuclear pore complexes (NPCs). Our studies reveal that the nuclear lamina network in mammalian somatic cells is less ordered and more complex than that of amphibian oocytes, the only other system in which the lamina has been visualized at high resolution. In addition, the NPC component Tpr likely links NPCs to the A-type lamin network, an association that appears to be regulated by C-terminal modification of various A-type lamin isoforms. Many questions remain, however, concerning the structure and assembly of lamin filaments, as well as with their mode of association with other nuclear components such as peripheral chromatin.

    On Sunday 12 June 2005, a site-wide security software upgrade will be performed on all CERN network equipment. This maintenance operation will cause at least 2 short network interruptions of 2 minutes on each equipment item. There are hundreds of such items across the CERN site (Meyrin, Prévessin and all SPS and LHC pits), and it will thus take the whole day to treat them all. All network users and services will be affected. Central batch computing services will be interrupted during this period, expected to last from 8 a.m. until late evening. Job submission will still be possible but no jobs will actually be run. It is hoped to complete the computer centre upgrades in the morning so that stable access can be restored to lxplus, afs and nice services as soon as possible; this cannot be guaranteed, however. The opportunity will be used to interrupt and perform upgrades on the CERN Document Servers.

    Effective collaboration and coordination between human and animal influenza networks is increasingly recognized as an essential requirement for the improved integration of data on animal and human viruses, the identification of unusual influenza A viruses infecting human, the evaluation of pandemic risk and the selection of candidate viruses for pandemic vaccines. • Training workshops, assessments and donations have led to significant increases in trained laboratory personnel and equipment with resulting expansion in both geographical surveillance coverage and in the capacities of NICs and other laboratories. This has resulted in a significant increase in the volume of information reported to WHO on the spread, intensity and impact of influenza. In addition, initiatives such as the WHO Shipment Fund Project have facilitated the timely sharing of clinical specimens and virus isolates and contributed to a more comprehensive understanding of the global distribution and temporal circulation of different viruses. It will be important to sustain and build upon the gains made in these and other areas. • Although the haemagglutination inhibition (HAI) assay is likely to remain the assay of choice for the antigenic characterization of viruses in the foreseeable future, alternative assays - for example based upon advanced recombinant DNA and protein technologies - may be more adaptable to automation. Other technologies such as microtitre neuraminidase inhibition assays may also have significant implications for both vaccine virus selection and vaccine development. • Microneutralization assays provide an important adjunct to the HAI assay in virus antigenic characterization. Improvements in the use and potential automation of such assays should facilitate large-scale serological studies, while other advanced techniques such as epitope mapping should allow for a more accurate assessment of the quality of a protective immune response and aid the development of additional criteria

    Complex networks appear in almost every aspect of science and technology. Previous work in network theory has focused primarily on analyzing single networks that do not interact with other networks, despite the fact that many real-world networks interact with and depend on each other. Very recently an analytical framework for studying the percolation properties of interacting networks has been introduced. Here we review the analytical framework and the results for percolation laws for a Network Of Networks (NONs) formed by n interdependent random networks. The percolation properties of a network of networks differ greatly from those of single isolated networks. In particular, because the constituent networks of a NON are connected by node dependencies, a NON is subject to cascading failure. When there is strong interdependent coupling between networks, the percolation transition is discontinuous (first-order) phase transition, unlike the well-known continuous second-order transition in single isolated networks. Moreover, although networks with broader degree distributions, e.g., scale-free networks, are more robust when analyzed as single networks, they become more vulnerable in a NON. We also review the effect of space embedding on network vulnerability. It is shown that for spatially embedded networks any finite fraction of dependency nodes will lead to abrupt transition

    Full Text Available This course presents an overview of the concepts of the neural networks and their aplication in the framework of High energy physics analyses. After a brief introduction on the concept of neural networks, the concept is explained in the frame of neuro-biology, introducing the concept of multi-layer perceptron, learning and their use as data classifer. The concept is then presented in a second part using in more details the mathematical approach focussing on typical use cases faced in particle physics. Finally, the last part presents the best way to use such statistical tools in view of event classifers, putting the emphasis on the setup of the multi-layer perceptron. The full article (15 p. corresponding to this lecture is written in french and is provided in the proceedings of the book SOS 2008.

    Currently, the most successful learning models in computer vision are based on learning successive representations followed by a decision layer. This is usually actualized through feedforward multilayer neural networks, e.g. ConvNets, where each layer forms one of such successive representations. However, an alternative that can achieve the same goal is a feedback based approach in which the representation is formed in an iterative manner based on a feedback received from previous iteration's...

    Citation between papers can be treated as a causal relationship. In addition, some citation networks have a number of similarities to the causal networks in network cosmology, e.g., the similar in-and out-degree distributions. Hence, it is possible to model the citation network using network cosmology. The casual network models built on homogenous spacetimes have some restrictions when describing some phenomena in citation networks, e.g., the hot papers receive more citations than other simultaneously published papers. We propose an inhomogenous causal network model to model the citation network, the connection mechanism of which well expresses some features of citation. The node growth trend and degree distributions of the generated networks also fit those of some citation networks well.

    Graphical abstract: Interdependent network reciprocity. Only those blue cooperative domains that are initially present on both networks survive. Abstract: This is an introduction to the special issue titled “Networks of networks” that is in the making at Chaos, Solitons & Fractals. Recent research and reviews attest to the fact that networks of networks are the next frontier in network science [1–7]. Not only are interactions limited and thus inadequately described by well-mixed models, it is also a fact that the networks that should be an integral part of such models are often interconnected, thus making the processes that are unfolding on them interdependent. From the World economy and transportation systems to social media, it is clear that processes taking place in one network might significantly affect what is happening in many other networks. Within an interdependent system, each type of interaction has a certain relevance and meaning, so that treating all the links identically inevitably leads to information loss. Networks of networks, interdependent networks, or multilayer networks are therefore a much better and realistic description of such systems, and this Special Issue is devoted to their structure, dynamics and evolution, as well as to the study of emergent properties in multi-layered systems in general. Topics of interest include but are not limited to the spread of epidemics and information, percolation, diffusion, synchronization, collective behavior, and evolutionary games on networks of networks. Interdisciplinary work on all aspects of networks of networks, regardless of background and motivation, is very welcome.

  19. Geneva calling: WHO resolution on mental disorders

    Directory of Open Access Journals (Sweden)

    Barbui Corrado

    2012-06-01

    Full Text Available Abstract Background A new resolution on mental, neurological and substance use disorders was adopted in January 2012 by the World Health Organization (WHO Executive Board. The resolution urges WHO and Member States to collaborate in the development of a comprehensive mental health action plan, to be submitted for discussion and approval to the WHO World Health Assembly. This commentary aims at rising awareness on the risk that this resolution may not fulfil its potential. Discussion Lack of political awareness and visibility of the resolution is a first major issue. Theoretically, Member States should be aware of the resolution and support its implementation at their respective national level, but in practice political commitment may not be high enough, and technical and financial resources made available may be limited. A second challenge is that the resolution suggests to work with Member States and technical agencies to promote academic exchange through which to contribute to policy-making in mental health. It is not straightforward, however, how such a statement may be effectively translated into action. A third key methodological aspect is how scientific evidence and factors other than scientific evidence will be handled. This seems particularly relevant in the field of mental health, where value-based decisions together with resource and feasibility considerations may be unavoidable. Summary We argue that WHO and Member States should work together to increase the visibility of the resolution, ensuring that Ministries of Health and other relevant components of the health systems are aware of the resolution and its implications. As the resolution urges for academic exchange, WHO should develop a plan for an explicit, inclusive and open call for support and collaboration, so that partners willing to contribute are not kept out from the process. The production of an action plan for mental disorders should be based on scientifically sound methodology. Such a methodology should be transparently described, for example in a WHO process document, to make it clear how individual-level recommendations and policy-level guidance are developed. WHO should establish and maintain an open forum of experts, scientists, health officials and user groups worldwide to interact and agree on values, preferences, feasibility, acceptability, implementability, equity and economic issues that should inform the action plan.

    Combines the hot topics of energy efficiency and next generation mobile networking, examining techniques and solutions. Green communications is a very hot topic. Ever increasing mobile network bandwidth rates significantly impacts on operating costs due to aggregate network energy consumption. As such, design on 4G networks and beyond has increasingly started to focus on 'energy efficiency' or so-called 'green' networks. Many techniques and solutions have been proposed to enhance the energy efficiency of mobile networks, yet no book has provided an in-depth analysis of the energy consumption issues in mobile networks nor offers detailed theories, tools and solutions for solving the energy efficiency problems.

  9. Hierarchical Network Design

    Communication networks are immensely important today, since both companies and individuals use numerous services that rely on them. This thesis considers the design of hierarchical (communication) networks. Hierarchical networks consist of layers of networks and are well-suited for coping...... with changing and increasing demands. Two-layer networks consist of one backbone network, which interconnects cluster networks. The clusters consist of nodes and links, which connect the nodes. One node in each cluster is a hub node, and the backbone interconnects the hub nodes of each cluster and thus...... the clusters. The design of hierarchical networks involves clustering of nodes, hub selection, and network design, i.e. selection of links and routing of ows. Hierarchical networks have been in use for decades, but integrated design of these networks has only been considered for very special types of networks...

    Many group-living animals construct transportation networks of trails, galleries and burrows by modifying the environment to facilitate faster, safer or more efficient movement. Animal transportation networks can have direct influences on the fitness of individuals, whereas the shape and structure of transportation networks can influence community dynamics by facilitating contacts between different individuals and species. In this review, we discuss three key areas in the study of animal transportation networks: the topological properties of networks, network morphogenesis and growth, and the behaviour of network users. We present a brief primer on elements of network theory, and then discuss the different ways in which animal groups deal with the fundamental trade-off between the competing network properties of travel efficiency, robustness and infrastructure cost. We consider how the behaviour of network users can impact network efficiency, and call for studies that integrate both network topology and user behaviour. We finish with a prospectus for future research. PMID:25165598

  20. Vulnerability and controllability of networks of networks

    International Nuclear Information System (INIS)

    Liu, Xueming; Peng, Hao; Gao, Jianxi

    2015-01-01

    Network science is a highly interdisciplinary field ranging from natural science to engineering technology and it has been applied to model complex systems and used to explain their behaviors. Most previous studies have been focus on isolated networks, but many real-world networks do in fact interact with and depend on other networks via dependency connectivities, forming “networks of networks” (NON). The interdependence between networks has been found to largely increase the vulnerability of interacting systems, when a node in one network fails, it usually causes dependent nodes in other networks to fail, which, in turn, may cause further damage on the first network and result in a cascade of failures with sometimes catastrophic consequences, e.g., electrical blackouts caused by the interdependence of power grids and communication networks. The vulnerability of a NON can be analyzed by percolation theory that can be used to predict the critical threshold where a NON collapses. We review here the analytic framework for analyzing the vulnerability of NON, which yields novel percolation laws for n-interdependent networks and also shows that percolation theory of a single network studied extensively in physics and mathematics in the last 50 years is a specific limited case of the more general case of n interacting networks. Understanding the mechanism behind the cascading failure in NON enables us finding methods to decrease the vulnerability of the natural systems and design of more robust infrastructure systems. By examining the vulnerability of NON under targeted attack and studying the real interdependent systems, we find two methods to decrease the systems vulnerability: (1) protect the high-degree nodes, and (2) increase the degree correlation between networks. Furthermore, the ultimate proof of our understanding of natural and technological systems is reflected in our ability to control them. We also review the recent studies and challenges on the

  3. Network Plus

    Science.gov (United States)

    Bender, Walter; Chesnais, Pascal

    1988-05-01

    Over the past several years, the Electronic Publishing Group at the MIT Media Laboratory has been conducting a family of media experiments which explore a new kind of broadcast: the distribution of data and computer programs rather than pre-packaged material. This broadcast is not directed to a human recipient, but to a local computational agent acting on his behalf. In response to instructions from both the broadcaster and the reader, this agent selects from the incoming data and presents it in a manner suggestive of traditional media. The embodiment of these media experiments is a news retrieval system where the news editor has been replaced by the personal computer. A variety of both local and remote databases which operate passively as well as interac-tively are accessed by "reporters." These "reporters" are actually software interfaces, which are programmed to gather news. Ideally, they are "broadcatching" that is to say, watching all broadcast television channels, listening to all radio transmissions, and reading all newspapers, magazines, and journals. 1 A possible consequence of the synthesis of media through active processing is the merger of newspapers and television (figure 1). The result is either a newspaper with illustrations which move 2 or, conversely, print as television output. The latter is the theme of Network Plus.

  4. Identity and Professional Networking.

    2017-06-01

    Despite evidence that large professional networks afford a host of financial and professional benefits, people vary in how motivated they are to build such networks. To help explain this variance, the present article moves beyond a rational self-interest account to examine the possibility that identity shapes individuals' intentions to network. Study 1 established a positive association between viewing professional networking as identity-congruent and the tendency to prioritize strengthening and expanding one's professional network. Study 2 revealed that manipulating the salience of the self affects networking intentions, but only among those high in networking identity-congruence. Study 3 further established causality by experimentally manipulating identity-congruence to increase networking intentions. Study 4 examined whether identity or self-interest is a better predictor of networking intentions, providing support for the former. These findings indicate that identity influences the networks people develop. Implications for research on the self, identity-based motivation, and professional networking are discussed.

    and hierarchy can be analyzed from a network approach. Within a network perspective, there are different levels of network, and a firm may not always has the power to “manage” innovation networks due to different levels of power. Based on the strength of a firm’s power, its role may varies from manager...

    Digital networks are the foundation of the information services, and play an expanding and indispensable role in our lives, via the Internet, email, mobile phones, etc. However, these networks consume energy, both through the direct energy use of the network interfaces and equipment that comprise the network, and in the effect they have on the operating patterns of devices connected to the network. The purpose of this research was to investigate a variety of technology and policy issues related to the energy use caused by digital networks, and to further develop several energy-efficiency technologies targeted at networks.

    Populations are seldom completely isolated from their environment. Individuals in a particular geographic or social region may be considered a distinct network due to strong local ties but will also interact with individuals in other networks. We study the susceptible-infected-recovered process on interconnected network systems and find two distinct regimes. In strongly coupled network systems, epidemics occur simultaneously across the entire system at a critical infection strength βc, below which the disease does not spread. In contrast, in weakly coupled network systems, a mixed phase exists below βc of the coupled network system, where an epidemic occurs in one network but does not spread to the coupled network. We derive an expression for the network and disease parameters that allow this mixed phase and verify it numerically. Public health implications of communities comprising these two classes of network systems are also mentioned.

    Railway operation is often affected by network effects as a change in one part of the network can influence other parts of the network. Network effects occur because the train runs may be quite long and since the railway system has a high degree of interdependencies as trains cannot cross....../overtake each other everywhere in the network. First this paper describes network effects in general (section 1). In section 2 the network effects for trains and how they can be measured by scheduled waiting time is described. When the trains are affected by network effects the passengers are also affected....... Therefore, sections 3 and 4 describe the network effects for passengers and how they can be measured using passenger delay models. Before the concluding remarks in section 6, section 5 discusses how the operation can be improved by examining network effects in the planning process. © 2012 WIT Press....

    The present and future power requirements of the Paris area and the structure of the existing networks are discussed. The various limitations that will have to be allowed for to lay down the structure of a regional transmission network leading in the power of the large national transmission network to within the Paris built up area are described. The theoretical solution that has been adopted, and the features of its final achievement, which is planned for about the year 2000, and the intermediate stages are given. The problem of the structure of the National Power Transmission network which is to supply the regional network was studied. To solve this problem, a 730 kV voltage network will have to be introduced.

  16. Do Policy Networks lead to Network Governing?

    DEFF Research Database (Denmark)

    Damgaard, Bodil

    This paper challenges the notion that creation of local policy networks necessarily leads to network governing. Through actor-centred case studies in the area of municipally implemented employment policy in Denmark it was found that the local governing mode is determined mainly by the municipality......’s approach to local co-governing as well as by the capacity and interest of key private actors. It is argued that national legislation requesting the creation of local policy networks was not enough to assure network governing and the case studies show that local policy networks may subsist also under...... hierarchical governing modes. Reasons why hierarchical governing modes prevail over network governing in some settings are identified pointing to both actor borne and structural factors. Output indicators of the four cases do not show that a particular governing mode is more efficient in its employment policy...

    A method and apparatus for protecting virtual machines. A computer system creates a copy of a group of the virtual machines in an operating network in a deception network to form a group of cloned virtual machines in the deception network when the group of the virtual machines is accessed by an adversary. The computer system creates an emulation of components from the operating network in the deception network. The components are accessible by the group of the cloned virtual machines as if the group of the cloned virtual machines was in the operating network. The computer system moves network connections for the group of the virtual machines in the operating network used by the adversary from the group of the virtual machines in the operating network to the group of the cloned virtual machines, enabling protecting the group of the virtual machines from actions performed by the adversary.

    In order to unveil the value of network connectivity, we formalize the construction of ecological networks in forest environments as an optimal control dynamic graph-theoretic problem. The network is based on a set of bioreserves and patches linked by ecological corridors. The node dynamics, built upon the consensus protocol, form a time evolutive Mahalanobis distance weighted by the opportunity costs of timber production. We consider a case of complete graph, where the ecological network is fully connected, and a case of incomplete graph, where the ecological network is partially connected. The results show that the network equilibrium depends on the size of the reception zone, while the network connectivity depends on the environmental compatibility between the ecological areas. Through shadow prices, we find that securing connectivity in partially connected networks is more expensive than in fully connected networks, but should be undertaken when the opportunity costs are significant.

    The objective of this study is to propose practical solutions aimed at completing and strengthening the existing arrangement for the control of nuclear proliferation through a control of financial as well as material or immaterial flows. In a first part, the author proposes a systemic analysis of networks of suppliers and demanders. He notably evokes the Khan's network and the Iraqi acquisition network during the 1993-2001 period. He also proposes a modelling of proliferation networks (supplier networks and acquisition networks) and of their interactions. In a second part, the author examines possible means and policies aimed at neutralising proliferation networks: organisation, adaptation and improvement of intelligence tools in front of proliferation networks, and means, limitations and perspectives of network neutralisation. He also briefly addresses the possibility of military action to contain proliferation flows

  20. Morphological neural networks

    The theory of artificial neural networks has been successfully applied to a wide variety of pattern recognition problems. In this theory, the first step in computing the next state of a neuron or in performing the next layer neural network computation involves the linear operation of multiplying neural values by their synaptic strengths and adding the results. Thresholding usually follows the linear operation in order to provide for nonlinearity of the network. In this paper we introduce a novel class of neural networks, called morphological neural networks, in which the operations of multiplication and addition are replaced by addition and maximum (or minimum), respectively. By taking the maximum (or minimum) of sums instead of the sum of products, morphological network computation is nonlinear before thresholding. As a consequence, the properties of morphological neural networks are drastically different than those of traditional neural network models. In this paper we consider some of these differences and provide some particular examples of morphological neural network.
