Deterministic lateral displacement (DLD) is a powerful bimodal separation scheme [1] based on regular obstacle arrays that in its basic embodiment sends particles in two different directions as a function of size. We add functionality to the technique by including gravitational forces, as a perturbation to particles transported by fluid flow, and as a way of transporting the particles through a st
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
The European X-ray Free Electron Laser (XFEL) will deliver 30,000 fully coherent, high brilliance X-ray pulses per second each with a duration below 100 fs. This will allow the recording of diffraction patterns of single complex molecules and the study of ultra-fast processes. Silicon pixel sensors will be used to record the diffraction images. In 3 years of operation the sensors will be exposed t
As part of the Swedish state-funded healthcare system, housing adaptations are used to promote safe and independent living for disabled people in ordinary housing through the elimination of physical environmental barriers in the home. The aim of this study was to describe the cohabitants' expectations and experiences of how a housing adaptation, intended for the partner, would impact their everyda
Isotopic proveniencing has been applied to human inhumations and cremations as well as fauna from the Viking Age site of Birka and the surrounding Mälaren region, located in east-central Sweden. Human enamel frominhumations has been measured for strontium, oxygen, and carbon isotope ratios (petrous bone from cremations was measured for strontium only) to obtain information on mobility and diet. Se
Introduction: Under-dosing is a recognized problem with current nicotine replacement therapy (NRT). Therefore, a new 6mg nicotine gum has been developed. To compare the nicotine uptake from the 6mg gum versus currently available NRT products, two pharmacokinetic studies were performed.Methods: In one randomized crossover study, 44 healthy adult smokers received single doses of 6, 4, and 2mg nicoti
We have developed a method to separate bacteria from red and white blood cells (henceforth collectively called blood cells) using acoustophoresis, for subsequent PCR detection. To maximize throughput, we have now investigated the effect of increased cell concentration on the separation. Increasing the blood concentration drastically decreases bacteria recovery, but we show that this can be remedie
Purpose: Recently, there has been increasing interest in the use of dual mobility systems in the treatment of hip instability. The aim of this study was to investigate the re-revision rate of dual mobility cup compared to different surgical concepts when used for first-time hip revisions due to recurrent dislocations. Methods: The data were derived from the Lithuanian Arthroplasty Register. For su
Gebel el Silsila (Mountain of Chain) is located between Kom Ombo and Edfu on both banks of the Nile where it reaches its narrowest point. The site is generally known for its many Pharaonic cenotaphs, stelai and the speos of Horemheb, but it was once also the world’s largest quarry. As such it was renowned for its high quality sandstone, and the stone was extracted and transported to all over Upper
In economic and management literature, the relationship between supplier and buyer can be more or less intimate. It can vary from market-driven with a constant change of suppliers to a value-driven relationship with one sole supplier. Purchasing strategies of construction companies have often been described as short-sighted, where price is the most considered aspect. Recent lean management literat
We present a method to first laterally position microparticles inside droplets by acoustic forces and then split the droplet into three daughter droplets to achieve a 2+fold enrichment of microparticles inside the center droplet. We show that acoustic forces can be applied to both manipulate polystyrene beads (5 μm) and red blood cells inside droplets. The presented technology opens up for develop
Carbonyl exchange between [MX3(13CO)]–(MX = PdCl, PtCl or PtBr) and 12CO has been studied by IR and 13C NMR spectroscopies as a function of temperature. The exchange is first-order in both CO and complex concentration, and the activation entropies are negative, suggesting an associative reaction mechanism. There is a small solvent effect, but no chloride dependence.

The rate constants for the chloride and bromide anations of Pd(H2O)42+, the chloride anations of PdCl3H2O−, the bromide anation of PdBr3H2O− and the acid hydrolysis of PdCl(H2O)3+, PdBr(H2O)3+, PdCl42−, and PdBr42− have been determined at 15, 25 and 35 °C using a stopped-flow technique. The ionic strength was 1.00 M and the supporting electrolyte perchloric acid. The obtained rate constants and th
Measles virus genotype B3 was isolated from patients during a measles outbreak in Copenhagen starting January 2006. Here we describe three cases: two children aged 9 and 22 months, respectively, and a 29-year-old man. All three patients were hospitalised. Several doctors examined both the children before the diagnosis of measles was established. The patients were not vaccinated against measles. Th
