Participation of stakeholders at the local level is evolving as a mechanism to address complex environmental problems, not least water pollution. Participation has been used as a tool for the economic and social empowerment of settlements within the catchment of the Korle lagoon in Ghana, particularly residents of the Old Fadama community that live in proximity to the lagoon. Using direct observat
This paper analyses regional public transport planning in Sweden. The aim is to provide an insight into how policy objectives are translated into action and to investigate how public transport measures are evaluated. The analysis is based on interviews with civil servants in five Swedish regions. Cost-benefit analysis is sparsely used (if ever) and the results further indicate that planning and ev
The impedance matching concept is employed in this paper to select the optimum gain of a VSC-HVDC damping controller. The damping controller of the DC link is based on control of active power in proportion to the difference in local frequency at the VSC-HVDC converter stations. To explain impedance matching, the small-disturbance electro-mechanical dynamics of a power system is transformed to an e
Background: Transarterial embolization with particles is a relatively common treatment method in both malignant and benign disorders. Permanent occlusion of the uterine arteries may sometimes be disadvantageous. Purpose: To compare the local tissue effects, possible side effects, and extent of recanalization following uterine artery embolization, using either degradable or non-degradable microsphe
Increasing climate change impacts are a major threat to sustainable urban development, and challenge current governance structures, including actors' responsibilities for dealing with climate variability and extremes. The need for distributed risk governance and citizen engagement is increasingly recognised; however, few empirical studies systematically assess interactions between citizens and mun
While previous research on projectification tends to focus on why processes of projectification emerge and in what contexts, this chapter use the example of European Union (EU) project funding in Swedish local government to analyse and understand how processes of projectification unfold in terms of transformation and adaptation. Key agents in processes of projectification are located and how these
Copper from vehicles disc brakes is one main contributor of the total copper found in the environment. Therefore, the U.S. Environmental Protection Agency (EPA) and the automotive industries started the Copper-Free Brake Initiative. The pad friction material is essentially composed of a binder, fillers, reinforcing fibres and frictional additives. Copper and brass fibres are the most commonly used
Objective To estimate, using numerical calculations, the depth of tissue damage in the uterus following balloon thermal endometrial destruction. Design A parameter, therapeutic depth, was defined. This was the maximum depth into the uterine myometrium, from the uterine cavity, at which a predefined temperature was reached after a certain time and with a constant intracavitary temperature. Setting
Large and persistent gaps in subnational public expenditure have important implications regarding growth, equity, and migration. In this context, we revisit the question of expenditure convergence across the American states to provide more nuanced evidence than found by a small number of previous studies. We employ a methodology due to Smeekes (Bootstrap sequential tests to determine the stationar
Epitaxial Bi-containing III–V crystals (III-V1-xBix) have attracted increasing interest due to their potential in infrared applications. Atomic-scale characterization and engineering of bulk-like III-V1-xBix properties (e.g., Bi incorporation and defect formation) are challenging but relevant to develop applications. Toward that target, we report here that the traditional surface-science measureme
Previous research has shown integrated planning to be important for achieving aims concerning more environmentally friendly transport operations, but less good at explaining prerequisites of implementation. This paper analyses how management and working practises in local authorities, here understood as steering cultures, affect implementation of integrated land-use and public transport planning a
The impact climate and land-use changes have on the hydrological conditions in peat bogs and lakes is often complex, but of great importance for the carbon budget and biodiversity in these ecosystems. Links and feedbacks between raised bog water table depth, lake level, net precipitation, hydrometeorological indices, and radial tree growth have been studied and identified in the Rėkyva wetland com
Counterion 23Na spin relaxation data are reported from the microemulsion phase in the AOT/water/isooctane system as a function of the water/AOT ratio, which determines the size of the aqueous droplets. The 23Na NMR measurements comprise three independent relaxation rates, allowing the individual spectral density values to be determined, as well as the second-order quadrupolar dynamic shift. The ef
Publisher Summary This chapter discusses the current status, of using nuclear magnetic resonance (NMR), to study the structure and dynamics of the holliday junction (HJ). Complex deoxyribonucleic acid (DNA) structures (e.g., triplexes, quadruplexes, junctions) pose difficult problems for study, by NMR, relative to the typical DNA duplexes, because they have nonstandard or distorted local conformat
Goals concerning reduced car traffic are found in most European cities, indicating a potential change in local transport policy and land use planning, which have traditionally been very car-centric. This paper analyses goals and measures to reduce car traffic in Swedish municipalities’ long-term transport and land use plans. Theoretically, the paper is based on an understanding of policies as part
As urban systems continue to grow worldwide, urban peripheries increase in number and typologies, which makes their planning a challenge for sustainable development. The aim of this article is to explore approaches and challenges related to the application of sustainable planning to urban peripheries. We reviewed the content of 102 papers related to sustainable planning in urban peripheries by app
There is an urgent need of improving the lives of 100 million slum dwellers until year 2020. The Habitat Agenda has identified self-help housing among other enabling housing strategies. This paper focuses on mapping organizations and different types of organized self-help housing (OSHH) projects since year 2000 with the aim of analyzing important lessons from practice. An international survey was
We have investigated crystal structure, chemical bonding, and electronic properties of the compounds Bi2Se3, BiSe, Bi4Se3, and Bi2Se by first-principles calculations within the density functional theory. The compounds are members of a general series of stacks (Bi2Se3)m(Bi2)n composed of five-layer blocks Se-Bi-Se-Bi-Se and two-layer blocks Bi-Bi. Both types of blocks can be considered as closed-sh
From a control design point of view, modern diesel engines are dynamic, nonlinear, MIMO systems. This paper presents a method to find low-complexity black-box dynamic models suitable for model predictive control (MPC) of NOx and soot emissions based on on-line emissions measurements. A four-input-five-output representation of the engine is considered, with fuel injection timing, fuel injection dur
We employ Non-equilibrium Green's functions (NEGF) to describe the real-time dynamics of an adsorbate-surface model system exposed to ultrafast laser pulses. For a finite number of electronic orbitals, the system is solved exactly and within different levels of approximation. Specifically i) the full exact quantum mechanical solution for electron and nuclear degrees of freedom is used to benchmark
