Development and characterization of sensitive, energy-independent solid-state photon dosemeters with high spatial and temporal resolution. Applications in clinical radiology and radiation protection.
AbstractModern medicine and health care rely on a variety of diagnostic and therapeutic equipment and methods that involve ionizing radiation. To guarantee quality and the safety of patients and staff, advanced radiation detectors and dosemeters are needed that have low energy and operate with directional independence for X-ray and γ-ray photons. Similar instruments are also of great importance fo
People and parking requirements : Residential attitudes and day-to-day consequences of a land use policy shift towards sustainable mobility
A land use policy shift is taking place in a growing number of cities regarding parking, whereby a conventional supplymanagement approach is being replaced with a parking management approach. As part of this policy shift, manycities are lowering their parking requirements. This study analysed changes in car use, car ownership, spatial parkingpatterns and the consequences for the everyday life of r
The Swedish joint action method against drink driving—a study of suspected drink drivers’ own experiences
Objective: In Sweden, a joint action method called SMADIT is in use, where the police quickly offer help from the social services or the dependency care and treatment service to suspected drink drivers. The objective of this article is to analyze the experiences of suspected drink drivers who accepted the offer of help and what it meant for them. The knowledge can be used to improve procedures and
The Tyranny of Small Decisions. Unsustainable Cities and Local Day-to-Day Transport Planning
Though new goals for sustainable cities and transport systems have been developed, decisions and planning at a local level often fail to achieve these ambitions. The purpose of this article is to analyse the factors in local decision-making and planning practice that conduce to urban sprawl and increased car traffic. The article analyses how the conscious application of so-called "day-to-day decis
Cooperation between police and social treatment services offering treatment to drink and drug drivers-experience in Sweden
Objective: To describe and analyze a measure that has been introduced in Sweden with the objective of quickly offering treatment for the alcohol or drug problems suspected drink or drug drivers may have. The goal of the measure is that every suspected drink or drug driver shall, as soon as apprehended by the police, be offered contact with the social services or the dependency are and treatment se
Impacts of urban morphology on reducing cooling load and increasing ventilation potential in hot-arid climate
Cooling buildings in urban areas with hot-arid climate put huge loads on the energy system. There is an increasing trend in urban energy studies to recognize the urban design variables and parameters associated with the energy performance of buildings. In this work, a novel approach is introduced to investigate the impacts of urban morphology on cooling load reduction and enhancing ventilation pot

Lightguiding of Fluorescence in Nanowires : Principles, Optimization and Implementation for Biosensing
Due to their unique optical properties, III-V nanowires are promising candidates for the development of efficient solar cells, LEDs and nanoscaled lasers. The interaction of nanowires with fluorescent molecules is also of interest, as these nanostructures can act as nanoscaled optical fibers. The light emitted by a fluorophore close to a nanowire surface can in fact couple into the supported waveg

A high-throughput deterministic lateral displacement device for rapid and sensitive field-diagnosis of sleeping sickness
We present a simple and rapid microfluidic device capable of extracting and concentrating the parasite causing the fatal disease sleeping sickness (SS) from blood. The device is based on deterministic lateral displacement (DLD) and constructed with a single inlet with flow induced by an ordinary syringe. The simplicity is crucial as the device is intended for use in the resource depraved areas whe
Sample preparation for single-cell whole chromosome analysis
In this work we present an integrated system for whole chromosome analysis of single bacterium. Using whole genome barcoding techniques, which offer direct and rapid microscopic visualization of the entire genome in one field-of-view, we aim to rapidly identify individual bacterium. We are developing our device to achieve the crucial, and difficult process of isolating a bacterium, removing the DN
Fluorescence microscopy of nanochannel-confined DNA
Stretching of DNA in nanoscale confinement allows for direct visualization of the genetic contents of the DNA on the single DNA molecule level. DNA stretched in nanoscale confinement also allows for studies of DNA-protein interactions and DNA polymer physics in confined environments. This chapter describes the basic steps to fabricate the nanostructures, to perform the experiments, and to analyze
Multiple depths in a deterministic lateral displacement device for field-diagnosis of sleeping-sickness
We present a simple and inexpensive device capable of extracting and concentrating the parasite causing sleeping sickness from blood. The device is aimed at being used in rural resource depraved areas where the disease is endemic; therefore simplicity is of paramount importance. The device is based on deterministic lateral displacement with a single inlet and flow induced by a syringe. Through an
Shear-driven motion of supported lipid bilayers in microfluidic channels
Detecting water transport through lipid membranes on a millisecond level using microfluidics and fluorescent dyes
Capillary driven separation on patterned surfaces
Deterministic lateral displacement (DLD) is a powerful bimodal separation scheme [1] based on fluid flow through regular obstacle arrays that in its basic embodiment sends suspended particles in two different directions as a function of size. We show that without the need to seal devices and without the need for fluidic connections or pumps, particle separation can be achieved by the passive flow
Shape-based particle sorting - A new paradigm in microfluidics
Conventional fractionation techniques fail to fully benefit from the variety in morphology and shape that is found among biological particles. Although light scattering in conventional FACS gives some information on the size and morphology of a particle, it is generally not capable of giving a definite number on specified dimensions of a small object. We demonstrate an approach where we select whi
