ssible designing of reinforcement constructions. Yet some problems in simulation of landslide situation do occur. Options for using different soil models and calculation schemes are being analyzed on the example of protective structures construction for railway tunnel in the city of Sochi region. Simulation of landslide slope condition is carried out using geotechnical software Plaxis conside­ring different soil models (Linear Elastic и Mohr-Coulomb) and «reconstruction» of structures displacements. The value of retaining wall displacement alongside landslide slope as well as retaining walls sections inner movement is being estimated by results of complex monitoring. Recent developments were causing threat to the safety of building and construction works continuation at the railway and also to the normal operation of structures lower down the slope.

Zirconium-based alloys have served the nuclear industry for several decades due to their acceptable properties for nuclear cores of light water reactors (LWRs). However, severe accidents in LWRs have directed research and development of accident tolerant fuel (ATF) concepts that aim to improve nuclear fuel safety during normal operation, operational transients and possible accident scenarios. This review introduces the latest results in the development of protective coatings for ATF claddings based on Zr alloys, involving their behavior under normal and accident conditions in LWRs. Great attention has been paid to the protection and oxidation mechanisms of coated claddings, as well as to the mutual interdiffusion between coatings and zirconium alloys. An overview of recent developments in barrier coatings is introduced, and possible barrier layers and structure designs for suppressing mutual diffusion are proposed.

The transit system serving Greater Vancouver has high ridership and a high rate of growth. Using as a base the well-designed, well-patronized trolleybus grid in the City of Vancouver, an inter-connected suburban bus network has been created, with radial, cross-radial, and local routes meeting on a timed connection basis at suburban shopping centres and other foci. Planners' thoughts for the future include greater emphasis on the micro and macro aspects of land use and relations to transit; the use of capital intensive modes for heavy trunk routes; and the use of various forms of para-transit for low-density and certain feeder applications.

The rise of video surveillance in the United Kingdom, in the form of the public installation of closed circuit television (CCTV), has been seen by several scholars as a contributing factor to the increasing exclusion of unwanted categories of people from city centers, a development often referred to as the 'commercialization' or 'purification' of the city. Drawing from field observations over three years in control rooms in Oslo, Norway, this article discusses whether CCTV systems in Oslo contribute to a similar process of exclusion. To do so, I compare the open street video surveillance system with two other CCTV systems - a shopping mall and a major transport center. The introduction of open street CCTV in Oslo in 1999 did not create social exclusion, but recent developments show the possibility remains. Although drug addicts and young people were the primary targets of surveillance in all three sites studied, ejections varied considerably from site to site. The shopping mall system had a higher ejection rate than the open street system, and was therefore the system with the clearest exclusionary effects. Reasons for the different ejection rates are discussed, in particular the social structure of the site under surveillance and the organizational relationships of CCTV operators to the policing agents connected to the surveillance system.

Warning Device

Since Roll-Over Protective Structures (ROPS) are mandatory on tractors, the number of fatalities caused in the event of an upset is definitely reduced. Nevertheless, fatal accidents caused by machine loss of stability are still of great concern. In fact, despite ROPS have reduced injury to agricultural operators, tractor stability is still a complex issue due to its high versatility in use, especially considering normal operations in field, when interactions with the environment such as soil morphology and climatic conditions are involved, as well as interactions with operator skills and experience. With the aim of collecting data on different variables influencing the dynamics of tractors in field, a commercial device that allows the continuous monitoring of working conditions and the active configuration of the machines was fitted on standard tractors in normal operation at the experimental farm of the Bologna University. The device consists of accelerometers, gyroscope, GSM/GPRS, GPS for geo-referencing and a transceiver for the automatic recognition of tractor-connected equipment. A microprocessor processes data and provides information, through a dedicated algorithm requiring data on the geometry of the tested tractor, on the level of risk for the operator in terms of probable loss of stability and suggests corrective measures to reduce the potential instability of the tractor.

Urban underground pipelines are the lifelines of the city. With the acceleration of city modernization, the traditional way to design and manage pipeline plans which relies on 2D diagrams has been difficult to secure the normal operation of the city. In this paper, a standard automatic 3D pipeline modelling process is proposed; a way to manage massive 3D scenes by scene graph is raised; three patterns of 3D integrated visualization are suggested; innovative stereo displays of pipeline analysis results are thought out. Eventually, a 3D urban underground pipeline plan aid system has been developed. At present, the system has been used in Xicheng Bureau of the Beijing Municipal Planning Commission, providing valuable decision-making information for urban underground pipeline network planning and management.

A new found interest in social history, recent developments in historical thought and methodology and a fresh awareness of the importance of gender-specific experience have led historians to question an ‘ordinary woman's place’ in Singa- pore's past. In the historiography of Singapore, there is a need to foreground the critical importance of the ah ku and karayuki-san in the sex,politics and society of the city, stressing not only alterations in their life and circumstance, but also variations in the role of the colonial government, and changes in the ideology of sex and social policy.

AbstractThis article has two goals. It reflects on the recent developments and agenda of an approach to historical writing that is now becoming known by the name global microhistory, and it analyses the attention which this approach pays to individual lives. It also explores some of the challenges in writing the biography of a city alongside the life history of a person. The city is Harbin, a former Russian-managed railway hub in Manchuria, today a province capital in Northeast China. The person is Baron Roger Budberg (1867–1926), a physician of Baltic German origin who arrived in Harbin during the Russo-Japanese war and remained there until his death, leaving published works and unpublished correspondence in German and Russian. My forthcoming book about Budberg and Harbin challenges the distinction between writing “biography”, on the one hand, and “history”, on the other, while navigating between the “micro” and “macro” layers of historical enquiry.

Local Conservative associations have traditionally run their affairs independently and have successfully resisted interference from Central Office. Far from constituting a ‘centralized machine’ (as authors such as McKenzie, Beer and Crossman have maintained) the main feature of Conservative organization has been its decentralized, voluntary character. Nowhere has resistance to control by the party headquarters been more determined than in the major provincial cities. Here, confederations of city constituency associations, financed mainly by local business interests, have virtually excluded the Central Office area agents from participating in constituency organization. Attempts by successive national party chairmen to bring the city associations into the Central Office orbit have regularly been rebuffed. Consequently, Central Office's recent success in integrating the city associations into its area office organization marks the end of an era. It raises the question of whether the Conservative organization is at last becoming as centralized as many commentators have long supposed it to be. This note describes recent developments and assesses their significance.
