- Spatial planning using a landscape approach has been recognized as being essential for reconciling ecological, cultural and socioeconomic dimensions in sustainable development (SuD). Although embraced as a concept, there is a lack of planning tools capable of incorporating multi-level, multifunctional and multi-sectoral perspectives, especially in a rural context. The departure point in this paper is the legal requirements for municipal comprehensive planning (MCP) in Sweden and an e-mail survey about incentives, stakeholder involvement, policy integration and implementation in MCP in all 15 Swedish mountain municipalities. The purpose of this explorative study is to examine whether MCP could be a tool in planning for SuD. Results indicate a general lack of resources and a low status of MCP that affect, and even limit, stakeholder involvement, policy integration and implementation. However, legal requirements for MCP are targeted at SuD, and municipal personnel responsible for planning appreciate the potential of MCP. Therefore, there is potential to develop the MCP into an effective landscape planning tool. To accomplish this, the status of an active planning process has to be raised, the mandate of the local planning agency has to be secured, and residents and land users have to be involved throughout the planning process.

- The term woodland key habitat (WKH) was launched in Sweden in 1990. Definitions for the concept have changed over the years, and today the WKH concept and its application are issues of debate in Sweden. Consequently, the Swedish Forestry Agency (SFA) initiated a collaborative process including forest stakeholders with the purpose to clarify the application and develop the inventory methodology of WKH. We have studied, by means of interviews and observations, participant perceptions of how endogenous and exogenous factors affect the collaborative process. During our research, we identified three game changers: the pause in WKH registration in northwestern Sweden that caused several participants to drop out of the process; budget allocations for new nationwide WKH inventories that put the process on hold; and formal instructions from the government that came nine months later and essentially re-initiated the collaborative process. Altogether, this not only affected the participants’ abilities, understanding and willingness to participate, but also the overall legitimacy of the process – indicating the difficulty of conducting policy development in collaborative form, especially when it is highly politicized since it impact on the participants’ anticipation of the process and its end results.

- Objectives To develop and evaluate a procedure for quantifying the hepatocyte-specific uptake of Gd-BOPTA and Gd-EOB-DTPA using dynamic contrast-enhanced (DCE) MRI. Methods Ten healthy volunteers were prospectively recruited and 21 patients with suspected hepatobiliary disease were retrospectively evaluated. All subjects were examined with DCE-MRI using 0.025 mmol/kg of Gd-EOB-DTPA. The healthy volunteers underwent an additional examination using 0.05 mmol/kg of Gd-BOPTA. The signal intensities (SI) of liver and spleen parenchyma were obtained from unenhanced and enhanced acquisitions. Using pharmacokinetic models of the liver and spleen, and an SI rescaling procedure, a hepatic uptake rate, K Hep, estimate was derived. The K Hep values for Gd-EOB-DTPA were then studied in relation to those for Gd-BOPTA and to a clinical classification of the patient’s hepatobiliary dysfunction. Results K Hep estimated using Gd-EOB-DTPA showed a significant Pearson correlation with K Hep estimated using Gd-BOPTA (r = 0.64; P < 0.05) in healthy subjects. Patients with impaired hepatobiliary function had significantly lower K Hep than patients with normal hepatobiliary function (K Hep = 0.09 ± 0.05 min-1 versus K Hep = 0.24 ± 0.10 min−1; P < 0.01). Conclusions A new procedure for quantifying the hepatocyte-specific uptake of T 1-enhancing contrast agent was demonstrated and used to show that impaired hepatobiliary function severely influences the hepatic uptake of Gd-EOB-DTPA. Key Points • The liver uptake of contrast agents may be measured with standard clinical MRI. • Calculation of liver contrast agent uptake is improved by considering splenic uptake. • Liver function affects the uptake of the liver-specific contrast agent Gd-EOB-DTPA. • Hepatic uptake of two contrast agents (Gd-EOB-DTPA, Gd-BOPTA) is correlated in healthy individuals. • This method can be useful for determining liver function, e.g. before hepatic surgery

INNOTRACK Deliverable 4.2.1 -- Simplified relation for the influence of rail/joint degradation on operational loads and subsequent deterioration
- 2007
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In this tentative report we present a summary of the work carried out during approximately the first nine months of the INNOTRACK project regarding the influence of rail/joint degradation on operational loads and subsequent deterioration. The focus is here on the vertical train–track interaction and related deterioration.The work within this field can be divided in two categories. The first concerns the collection of input and validation data. In this category the current deliverable includes measurements of in-field axle loads, in-field monitoring of squats and compilation of material data.The second category is the actual numerical simulation and resulting quantifications of increased operational loads and deteriorations. Here the deliverable includes a state-of-the-art study of the effect of material characteristics on material deterioration and the practical implications. Further, the deliverable contains reports of parametric studies of the influence of rail corrugation, the growth of larger rail cracks, the influence of the design of insulated joints and the influence of rail squats.
