Improving Urban Public Operation: Experience Of Rostov-On-Don (Russia)

This paper estimates experience of development of urban public transport in city Rostov-on- Don, Russia. The main aims of policy of municipal authorities on reforming public transport are analysed. The integrated decision of a problem included achievement of the following purposes: creation most appropriate structure of management of city public transport, change of form of ownership of public transport operators, improvement of competition on the entry of market of transport services, optimization of a routes network of public transport.Institute of Transport and Logistics Studies.

(On)begrensde Technologie

Er zijn voorspellingen gedaan, bijvoorbeeld door het World Economic Forum, dat we aan de vooravond van een ‘vierde industriële revolutie’ staan, die draait om het meer verbonden raken van informatie- en productieprocessen. Als dat zo is, zal dat maatschappelijke gevolgen voor Zuid-Holland en daarmee implicaties voor het beleid van de provincie hebben. De onderzoeksvraag van deze studie is dan ook: “Wat is de maatschappelijke [sociale, economische en ruimtelijke] invloed van nieuwe productie- en informatietechnologieën? En, hoe verandert dat de wijze waarop we als provincie aan de opgaven van de toekomst werken?”. Hiertoe hebben we een literatuurstudie over de potentiële maatschappelijke gevolgen van nieuwe technologie verricht en daarna in interactie met stakeholders en de provincie vier scenario’s ontwikkeld

Quality control for the first large areas of triple-GEM chambers for the CMS endcaps

The CMS Collaboration plans to equip the very forward muon system with triple-GEM detectors that can withstand the environment of the High-Luminosity LHC.This project is at the final stages of R&D and moving to production. A large area of several 100 m 2 are to be instrumented with GEM detectors which will be produced in six different sites around the world. A common construction and quality control procedure is required to ensure the performance of each detector.The quality control steps will include optical inspection,cleaning and baking of all materials and parts used to build the detector,leakage current tests of the GEM foils,high voltage tests,gas leak tests of the chambers and monitoring pressures time,gain calibration to know the optimal operation region of the detector,gain uniformity tests, and studying the efficiency,noise and tracking performance of the detectors in a cosmic stand using scintillator

Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures

Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo
