The colloidal stability of lipid based cubosomes, aqueous dispersion of inverse bicontinuous cubic phase, can be significantly increased by a stabilizer. The most commonly used stabilizers are non-ionic tri-block copolymers, poloxamers, which adsorb at the lipid-water interface and hence sterically stabilize the dispersion. One of the challenges with these synthetic polymers is the effect on the i
The purpose of this study was testing and performance simulation of an innovative tracking hybrid solar system being developed by the Swedish Company Arontis. The Solar8 collector produces both electrical and thermal energy in one system. Its performance was compared with conventional photovoltaic panels and solar thermal collectors working side-by-side which are already on the market. The solar8
Consumer packaging has become increasingly important as a value adding product service system, since packages shape the consumer’s experience of product use as well as accelerating and affecting the first purchase decision. Recent research in food packaging has resulted in technological innovations that provide information on the real shelf life and expiration of food products as a service to user
A device monitors a blood path from a blood vessel access of a human subject through an extracorporeal blood processing apparatus and back to the blood vessel access. A pumping device in the blood path is operable to pump blood through the blood path from the blood withdrawal device to the blood return device. The monitoring device obtains pressure data from a pressure sensor arranged upstream of
In this egocentric article I describe briefly the segmental phonology of my own southern Swedish idiolect. I grew up in Getinge in central Halland, about 20 km north of Halmstad, speaking a regional variant of southern Standard Swedish. Although my dialect has certainly changed somewhat after I moved to Lund in 1964 at the age of 20, I believe that I still retain the basic pronunciation of vowels
A spherical reference field is used to construct a digital holography system with a demonstrated resolution down to 228 line pairs per mm. The reference field origin from a GRIN lens placed 1mm from the illuminated object. This allows the use of a standard sensor to record the hologram with the required numerical aperture. The image is determined by evaluation of the Rayleigh-Sommerfeld diffraction i
Popular Abstract in Swedish Så gott som alla metaller reagerar vid normala omständigheter med syret i luften och oxideras, vilket förändrar materialets egenskaper. T.ex. rostar järn efter hand, något som alla bilägare är bittert medvetna om. Oxider behöver dock inte vara negativa, utan kan även fungera som barriärer mot fortsatt korrosion, isolerande skikt i mikroelektronikkomponenter m.m. FöljaktThe oxidation of Rh, Pd and Pt is studied under conditions ranging from ultra high vacuum to ambient pressures, with emphasis on a complete understanding of the geometry of the various oxide structures found. The investigations use a combination of various experimental methods, including high resolution core level spectroscopy, low energy electron diffraction, surface x-ray diffraction and scannin
This paper maps social structure, poverty, wealth and economic inequality in Stockholm from 1650 to 1750. We begin by establishing the social structure, using census data and other sources. To study wealth and poverty, the main sources are a sample from the wealth tax of 1715, and probate inventory samples from 1650, 1700 and 1750. These provide detailed and sometimes surprising insights into the
1. We manipulated the size hierarchy in broods of marsh tits (Parus palustris L.) by simulating hatching asynchrony to study how nestlings of different competitive ability, allocate their share of parental feedings to different growth strategies. 2. The mean rate of mass increase and the mass when the growth curve had reached an asymptote increased with the predicted competitive ability of nestlin
In this study, a high-speed, fast responsive, non-intrusive ultrasonic thermometry system was proposed as a potential candidate for overcoming the disadvantages of thermocouples. The principle of this system is based on the thermal dependence of the speed of sound, and the temperature is measured by detecting the flight time of ultrasonic wave (USW) between the transmitter and the receiver. For a
Despite nearly two decades of disability research highlighting the need to take greater account of disabled people's sexualities, sexuality is still largely a taboo subject in disability services, thus limiting service users’ possibilities to express their sexuality. In this article, I aim to show how Swedish personal assistance managers organize sexual facilitation, that is, assistance from perso
Cycling provides numerous benefits to individuals and to society but the burden of road traffic injuries and fatalities is disproportionately sustained by cyclists. Without awareness of the contributory factors of cyclist death and injury, the capability to implement context-specific and appropriate measures is severely limited. In this paper, we investigated the effects of the characteristics rel
Popular Abstract in Swedish Svensk Kärnbränslehantering AB, SKB, har i uppdrag att ta hand om allt radioaktivt avfall från de svenska kärnkraftverken. En av förutsättningarna för att SKB ska få tillstånd att uppföra inkapslings- och slutförvars¬anläggningarna är att metod och teknik för att försluta kapslarna finns. De förslutna kapslarna ska uppfylla de krav på långsiktig säkerhet som SKB, myndigThis thesis presents the development to reliably seal 50 mm thick copper canisters containing the Swedish nuclear waste using friction stir welding. To avoid defects and welding tool fractures, it is important to control the tool temperature within a process window of approximately 790 to 910°C. The welding procedure requires variable power input throughout the 45 minute long weld cycle to keep th
Heart transplantation (HTx) is severely limited by a shortage of donors. This thesis aimed to investigate the effectof variables used to match donors to recipients in HTx.Methods: Data from the ISHLT registry was used to study: I: Identical versus compatible non-identical ABOmatchingin 3,589 AB HTx recipients. II: Outcomes of 94 ABO-incompatible transplants were compared to anABO-compatible group.
Homelessness as a political and social dominion has a number of features that make it particularly difficult to tackle. In addition to being a wicked problem, homelessness offers several analytical avenues. How do these characteristics affect the evaluation of programmes and projects aspiring to combat homelessness? Dissimilar pictures and solutions regarding homelessness in the US and in European
Adaptor proteins assist proteases in degrading specific proteins under appropriate conditions. The adaptor protein YjbH promotes the degradation of an important global transcriptional regulator Spx, which controls the expression of hundreds of genes and operons in response to thiol-specific oxidative stress in Bacillus subtilis. Under normal growth conditions, the transcription factor is bound to
