Glass sheets investigated regarding their Po-210 signal originating from indoor radon exposure will have a depth distribution down to about 100 nm. The geometrical probability of implantation into glass of glass-attached radon daughter activity in one alpha recoil event is 50%. A particulate layer on the glass sheet (dust, grease or other particles) will stop the alpha recoil nucleus partly or tot

Popular Abstract in Swedish Tyfoidfeber är en sjukdom som orsakas av bakterien Salmonella typhi. Denna bakterie, som sprids via vatten eller föda, orsakar buksmärtor, feber och illamående. Om infektionen inte behandlas med antibiotika, kan bakterien sprida sig till blodet och leda till döden. Årligen rapporteras 16 miljoner fall av salmonella i världen och av dessa får ungefär 600 000 dödlig utgånThis study investigates the interaction between dendritic cells (DC) and the Gram negative intracellular bacterium Salmonella typhimurium. Using in vitro and in vivo approaches, the capacity of DC to directly and indirectly present antigens from Salmonella-infected cells, cytokine production by infected DC, and activation of bacteria-specific T cells was analyzed. These studies revealed differenti

This work concerns an experimental study of pressure drop and heat transfer for turbulent flow inside a U-duct. Such duct geometries can be found in many engineering applications where cooling air extracts heat from hot internal walls of the duct, e.g., passage cooling inside gas turbine blades. Both friction factors and convective heat transfer coefficients were measured inside a U-duct for three

The Moving City: Processions, Passages and Promenades in Ancient Rome focusses on movements in the ancient city of Rome, exploring the interaction between people and monuments. Representing a novel approach to the Roman cityscape and culture, and reflecting the shift away from the traditional study of single monuments into broader analyses of context and space, the volume reveals both how movement

Mary Wollstonecraft is a writer whose work continues to provoke scholarly debate. But Wollstonecraft the historical figure often obscures her importance as a philosopher. Halldenius explores Wollstonecraft’s political philosophy, focusing on her treatment of republicanism and independence, to propose a new way of reading her work – that of a ‘feminist republican’. Wollstonecraft’s works of fiction

Pulsar binaries are important targets for ground-based and future space-borne gravitational-wave (GW) detectors. In order for improving detector design and assessing detector performances, it is a prerequisite to understand the astrophysics of GW sources such as the population size or merger rates. Here, we summarize recent results for Galactic merger rates of two known types of pulsar binaries: (

This chapter describes a personal aerosol sampler with size fractionation and time resolution that gives samples for elemental analysis. An impaction stage collects coarse particles and a filtration stage collects finer ones. Sampling in consecutive time intervals is performed on different impaction and filtration surfaces. These sampling surfaces corresponding, for example, to 15-min intervals, m

Gaia is ESA’s space astrometry mission with a foreseen launch date in early 2012. Its main objective is to perform a stellar census of the 1000 Million brightest objects in our galaxy (completeness to V=20 mag) from which an astrometric catalog of micro-arcsec level accuracy will be constructed. A key element in this endeavor is the Astrometric Global Iterative Solution (AGIS). A core part of AGIS

Proficiency in writing is a central graduate attribute of higher education. In practice, this means that students are expected to acquire both generic and discipline-specific writing skills that will be beneficial for their professional lives. Although the learning outcomes for many courses include the ability to express oneself in writing, a predominant function of writing is that of mere testing

The influence of counterions and co-ions on the stability and thickness of foam films stabilized by anionic dodecyl sulfate (DS(-)) has been studied in a thin film pressure balance. Particularly, the effect on the properties of foam films of (i) the counterions Li(+), Na(+), and Cs(+) of DS(-) and (ii) monovalent inorganic salts added to sodium dodecyl sulfate solutions is considered. Generally, a
