<p>Cycling is deeply embedded in Dutch society and town planning. The latest development is that of bicycle fast lanes. In a country that is largely located in a river delta, with waterways literally everywhere, creating those fast lanes more often than not also requires building one or more bicycle bridges. Ipv Delft is a Dutch bridge design and engineering office, specializing in cycling infrastructure. As such, we have plenty of experience in designing bicycle bridges on bicycle fast lanes. Our integrated design method, which was the basis for the Brief Dutch Design Manual for Bicycle and Pedestrian Bridges (2017) has played a mayor role in creating bicycle bridge designs that not only look good, but are also cost-effective, within budget and adjusted to the requirements of the location, its stakeholders and the bridge users.</p><p>Our lecture will focus on several projects that illustrate how we work and why we believe an integrated approach is the way to go.</p>

The coastal zones of Siberian large cities are characterized by high demand at various historical stages. Coastal territories are considered as potential reserves of the urban environment, their functions have great dynamics and high natural potential. The objective of the research is identifying the influence of environmental factors on the zones’ landscape and town planning reorganization in the structure of the Siberian large cities' coastal territories. Research methods are an integrated approach which involves considering the research object as an element of a single town-planning structure, excluding the possibility of making limited and incomplete decisions. The study results are to build a green river facade as proposing solutions to environmental problems of “buffr zones”. Significance of the study is to preserve the environmental balance of the large Siberian Rivers’ territories. This comprehensive approach involves consideration of the research object as an element of a single town-planning structure. First of all it requires the identification of optimal territories for placing point objects in a complex terrain territory and choosing the most cost-effective and efficient reconstruction and revitalization methods, within the development of methods for their application in local conditions.

Purpose Compared with conventional design methods, strut-and-tie modeling is a more suitable and even a superior method for the reinforcement layout design of structural members with uncommon geometrical shapes and/or regions essentially subject to shear effects. Because the determination of the optimum strut-and-tie model for each of the members is an important task, the implementation of a topology optimization method could be useful before the detailing stage. Design/methodology/approach Optimum reinforcement layout of a concrete frame was designed by an integrated approach, which consists of the topology optimization and strut-and-tie modeling methods. Subsequently, an experimental comparison of the new model with the conventional model was performed based on their structural behaviors. Findings Depending on the experimental results, it was concluded that the new integrated design method presents more successful results than does the conventional method for the design of reinforced concrete (RC) members. Originality/value The preference of the new method will facilitate the design process by eliminating the experience required of design engineers.

The study is devoted to the issues of forming the concept of a mixed residential environment. The relevance of the research topic is due to the growth in housing construction in commuter belts of megacities and adjacent territories. Relevance of the study is also substantiated by such prerequisites as uneven distribution of housing among various categories of citizens, problems of territory insecurity with the whole complex of infrastructure necessary for the population, problems of significant territorial remoteness of jobs from places of residence. Moreover, a faceless, depressing and largely anti-human environment is created during the development of large territories due to the architecturally unattractive, heterogeneous, non-ergonomic high-rise high-density buildings. All the above-mentioned reasons cause the necessity for searching for new methods of organizing residential development that is comfortable for citizens and cost-effective for the developer. The scientific novelty of the study is to justify and define an integrated approach to understanding mixed residential development, to propose the principles, methods and tools of mixed residential development in the integrated development of the territory in the commuter belts of the metropolis, based on the most progressive foreign analogues studied. Also, scientific novelty lies in studying the index of mixed use according to the world analogues of the projects of Integrated Territory Development and recommendations on implementing this approach in Russia when planning projects of the Integrated Territory Development (ITD).

This article undertakes to show the way that has led to the statutory decriminalization of euthanasia-related murder and assisted suicide in the Kingdom of the Netherlands. It presents the evolution of the views held by Dutch society on the euthanasia related practice, in the consequence of which death on demand has become legal after less than thirty years. Due attention is paid to the role of organs of public authority in these changes, with a particular emphasis put on the role of the Dutch Parliament – the States General. Because of scarcity of space and limited length of the article, the change in the attitudes toward euthanasia, which has taken place in the Netherlands, is presented in a synthetic way – from the first discussions on admissibility of a euthanasia-related murder carried out in the 1970s, through the practice of killing patients at their request, which was against the law at that time, but with years began more and more acceptable, up to the statutory decriminalization of euthanasia by the Dutch Parliament, made with the support of the majority of society.

Acupuncture in combination with antiretroviral therapies is a potentially useful treatment for HIV-related symptom relief in resource-poor settings. Traditional Chinese medicine has a long history of being used to enhance immune function. In the setting of HIV, Chinese traditional medicine allows for symptom treatment without adding extra medications to a complex drug regime. This paper provides details of a project at Mae On Hospital in rural northern Thailand where allopathic/conventional treatments are used in tandem with acupuncture. A preliminary evaluation of the project suggests that an integrated approach to symptom relief is viewed positively by respondents receiving acupuncture, though further studies are required to confirm the association between acupuncture and symptom relief. The project also demonstrates the feasibility of developing a cost-effective acupuncture programme using local healthcare staff.

For an electric vehicle (EV) with a continuously variable transmission (CVT), a novel convex programming (CP)-based co-design method is proposed to minimize the total-cost-of-ownership (TCO). The integration of the electric machine (EM) and the CVT is the primary focus. The optimized system with co-design reduces the TCO by around 5.9% compared to a non-optimized CVT-based EV (based on off-the-shelf components) and by around 2% compared to the EV equipped with a single-speed transmission (SST). By taking advantage of the control and design freedom provided by the CVT, the optimal CVT, EM and battery sizes are found to reduce the system cost. It simultaneously finds the optimal CVT speed ratio and air-flow rate of the cooling system reducing the energy consumption. The strength of co-design is highlighted by comparing to a sequential design, and insights into the design of a low-power EV that is energy-efficient and cost-effective for urban driving are provided. A highly integrated EM-CVT system, which is efficient, low-cost and lightweight, can be expected for future EV applications.

To date, very few publications have been found that describe how small and medium enterprises (SMEs) are adopting knowledge management (KM). The same is true concerning attempts to develop a framework to help them implement it. To redress this, this paper presents the results of four case studies conducted in UK SMEs to examine their KM implementation effort. In addition, a new integrated framework developed by the authors was evaluated to determine its applicability in this business sector. The methodology employed to conduct the studies is described and each of the cases is then presented. The results are analysed and key lessons or findings gathered from the companies are highlighted. Comments received from the companies with respect to the integrated framework were positive and favourable. It is hoped that the information accrued from the case studies, together with the integrated framework, will help to pave the way for SMEs to accomplish KM.

Summary This article deals with the reception of Billy Graham and modern evangelicalism in the fragmented society of the Netherlands in 1954. It takes its departure from the stream of newspaper articles published between February and June in response to the Greater London Crusade and Graham’s first large scale rally in Amsterdam’s Olympic Stadium. The analysis of the reports in different newspapers, which represent the different social groups (catholic, protestant, socialist and liberal) in Dutch society, reveals a significant shift in the way Billy Graham was perceived: from initial scepticism to mild appreciation. This change in press coverage, it is concluded, is mainly due to the different way in which Billy Graham presented himself compared with the large-scale publicity which surrounded his campaign.
