Urbanization growth and aging infrastructures necessitate new infrastructure construction projects in congested urban areas. Urban construction projects interrupt the regular on-road vehicle traffic flow that affects air pollution concentration in the adjacent areas. The project schedule, however, is a possible contributor to the air pollution which has been neglected to date. This research propos
The high vehicle congestion is the main contributing factor to air pollution originated from the engine's combustion in many urban areas. Grade separation projects have been used to solve this problem and have resulted in overall air pollution reduction in many cases. Many grade separation projects are constructed near sensitive urban locations accommodating susceptible individuals. This research
This thesis is mainly concerned with investigations of approximation problems on spaces of analytic functions on the unit disc in the complex plane, which naturally arise in connection to spectral problems of certain classes of linear operators acting on the spaces in question. For instance, quasi-nilpotency of certain analytic paraproducts on the Hardy spaces and on the Bergman spaces are investi
BACKGROUND AND OBJECTIVES: Curative treatment for locally advanced head and neck tumours often includes reconstructive surgery using a microvascular free flap. Effective recuperation is essential but may be impeded by postoperative donor site pain. The aim of this study was to evaluate the effects of a continuous popliteal block on postoperative pain after fibular graft harvesting.MATERIAL AND MET
Vertically aligned metal halide perovskite (MHP) nanowires are promising for various optoelectronic applications, which can be further enhanced by heterostructures. However, present methods to obtain free-standing vertically aligned MHP nanowire arrays and heterostructures lack the scalability needed for applications. We use a low-temperature solution process to prepare free-standing vertically al
Microbial stoichiometry has become a key aspect in ecological research as shifts in microbial C:N, C:P and N:P ratios upon nutrient addition are presumed to give insight into relative nutrient limitations for soil microorganisms–with far-reaching implications for biogeochemical processes. However, this expectation has never been tested against direct methods of microbial growth responses to nutrie
In situ structural and chemical state characterization of Rh/CeO 2 and Ni/CeO 2 catalysts during atmospheric pressure CO 2 methanation has been performed by a combined array of time-resolved analytical techniques including ambient-pressure X-ray photoelectron spectroscopy, high-energy X-ray diffraction and diffuse reflectance infrared Fourier transform spectroscopy. The ceria phase is partiall
The medical landscape is a constantly changing field, both in relation to new knowledge and innovative technology as well as a changing world. Some examples are new emerging diseases and changing welfare societies. In ethnological and folkloric research there is a long tradition of exploring and reflecting upon this kind of issues from a broad variety of methodological and theoretical perspectivesIn this paper I ask how ethnology with a medical humanities perspective can use the term Anthropocene to better understand the emerging fact that we soon will stand without functional antibiotics.
Detta är den åttonde skriften i en serie småskrifter som vi publicerar och som alla handlar vetenskap och beprövad erfarenhet, med fokus på ett eller annat tillämpningsområde. Hittills har vi belyst följande områden: medicin, juridik, skola, miljö, politik och socialtjänst. Detta nummer ägnas åt vård. Våra kartläggningar har lärt oss att begreppet vetenskap och beprövad erfarenhet definieras olika
Numerical simulations and parametric studies of glued-in rods in cross-laminated timber have been performed. The simulations were based on 3D finite element analysis, using a cohesive surface model for the bond-lines between the laminations and the bond-line along the rod. The parametric studies investigated the influence of the glued-in length, the rod diameter, and the rod-to-grain angle on the
Some light beams rotate as they propagate. If it is not the polarization vector, but the phase structure that rotates, the beam is said to carry orbital angular momentum (OAM). Such beams exhibit a helical phase front, where the phase rotates around a symmetry center. Because the phase in the center is undefined (and the intensity there is therefore zero), it is often termed a phase singularity or
This work, framed in the IEA SHC Task 51 “Solar Energy in Urban Planning” presents an illustrative perspective of solar energy in urban planning through the analysis of 34 international case studies conducted in 10 countries. The aim here is to examine challenges, barriers and opportunities for active solar systems and passive solar strategies by taking into consideration interrelated technical an
Quantum field theories containing scalar fields with equal quantum numbers allow for a mixed kinetic term in the Lagrangian. It has been argued that this mixing must be taken into consideration when performing renormalization group (RG) analyses of such a theory. However, from the fact that scalar kinetic mixing does not correspond to a physical observable, we show that no extra parameters need to
The aim is to investigate associations between sexual orientation and experience of suicide thoughts and suicide attempts. The 2012 public health survey in Scania, southern Sweden, is a cross-sectional population-based study including 28,029 participants aged 18–80 with 51.7% participation. The associations between sexual orientation and experience of suicide thoughts and attempts were investigate
In a multicentre European hospital study we measured influenza vaccine effectiveness (IVE) against A(H3N2) in 2016/17. Adjusted IVE was 17% (95% confidence interval (CI): 1 to 31) overall; 25% (95% CI: 2 to 43) among 65-79-year-olds and 13% (95% CI: -15 to 30) among those ≥ 80 years. As the A(H3N2) vaccine component has not changed for 2017/18, physicians and public health experts should be aware
The type of regional innovation system (RIS) strongly affects possibilities of paths of industrial transformation. This paper argues that traditional manufacturing districts, corresponding to specialized RISs and characterized by various nuclei of specialization and know-how, may foster different trajectories in combination with extra-regional networks. In particular, the paper analyses the interp
