Rationale: Knowledge regarding the prevalence and shared and unique characteristics of the restrictive spirometric pattern (RSP) and preserved ratio impaired spirometry (PRISm) is lacking for a general population investigated with post-bronchodilator spirometry and computed tomography of the lungs. Objectives: To investigate shared and unique features for RSP and PRISm. Methods: In the Swedish CAr

We demonstrate that the detected emission intensity from YOYO-labeled DNA molecules confined in 180 nm deep Si/SiO2 nanofunnels changes significantly and not monotonically with the width of the funnel, an emission enhancement that is only detected for emitted light polarized parallel to the channel. We explain the enhancement effect as being due to optical phenomena in the channels. The enhancemen

We present a deterministic-lateral-displacement (DLD) device that extends the capabilities of this traditionally sizebased particle separation technique to also be sensitive to density. By the use of T-shaped posts instead of the normally cylindrical posts the particle trajectory through the device will be a function of its vertical position which in turn is determined by the buoyancy of the parti

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

We present a significantly improved acoustophoresis method to separate bacteria from red and white blood cells. As much as 98% of the bacteria were recovered, while only 0.06 % of the red and white blood cells remained. This 1600-fold relative enrichment was achieved by adjusting the center medium density, tightly controlling the chip temperature and stabilizing the fluid flows. This is a crucial

The recent several years we developed the Scheimpflug lidar method. We combined an invention from the 19th century with modern optoelectronics such as diode lasers and CMOS array from the 21st century. The approach exceeds expectations of background suppression, sensitivity and resolution beyond known from time-of-flight lidars. We accomplished multiband elastic atmospheric lidars for resolving si

Adaptive plasticity processes are required involving neurons as well as non-neuronal cells to recover lost brain functions after an ischemic stroke. Recent studies show that gamma-Aminobutyric acid (GABA) has profound effects on glial and immune cell functions in addition to its inhibitory actions on neuronal circuits in the post-ischemic brain. Here, we provide an overview of how GABAergic neurot

We present a microfluidic system to control the position of particles (polystyrene beads or astrocyte cells) in hydrogel droplets using bulk acoustic standing waves. Droplets comprising hydrogel precursor solution, photoinitiator and (bio-)particles were generated and acoustic forces focused the beads to the droplet center line. Droplets were cross-linked by exposure to UV-light. With the acoustic

This contribution reports a novel method for cell-supernatant separation inside nanoliter droplets with separation efficiencies for single cells of 100% at flow speeds of 2 mm/s. Cells are focused in nanoliter droplets using bulk acoustic waves before the droplet is split at a bifurcation into a supernatant- and a cell-containing droplet. The method enables upconcentration of cells, cell washing,

There are currently no reliable biomarkers to predict clinical response to pharmacological treatments of depressive disorders. Peripheral blood 5-hydroxytryptamine (5-HT; serotonin) has been suggested as a biomarker of antidepressant treatment response, but there has not been an attempt to systematically summarize and evaluate the scientific evidence of this hypothesis. In this systematic review w

The challenge of urbanisation, caused by an increase in city population, is increasing demand for imported food products. Food supplies may be impacted by the exponential increase in food demand caused by a constantly expanding global population. Growing and producing food in urban areas has now become a common practice. Addressing food system challenges through the adoption of urban farms on gree

This chapter offers a theoretical approach to the study of humorous digital memes. Using vaccination and pandemic policy memes on Reddit as examples, the chapter’s main contribution is an understanding of memes as forms of symbolic levelling that reflect and construct civic trust or distrust. Arguing for a theoretically informed methodological approach sensitive to memes’ polysemic ambiguity, seve

Physics classrooms are still clearly marked by practices belonging to a certaineducational past, while teachers are increasingly being asked to teach in lignment with current equality, diversity and inclusion agendas. At the core of this temporal disconnect are teachers’ practices, which are strongly marked by normative regimes in terms of gender, race, ethnicity, class and other social factors. M

Popular Abstract in Swedish Datorsimuleringar, konsten att modellera verkliga eller tänkta händelser med hjälp av en dator och ett lämpligt simuleringsprogram, har blivit ett dominerande verktyg inom tekniska och naturvetenskapliga områden, likväl inom akademiska och industriella tillämpningar. Trots att experimentella studier har ett vedertaget erkännande inom diverse forskningsstudier har den snThis thesis concerns the study of Fluid-Structure interaction phenomena among deforming and (non-deforming) vibrating objects under unsteady fluid fl ow exposures. This multi-physical phenomenon is widely encountered in real-life situations and therefore it is of significant importance to understand the underlying physics. The trend is that both industrial and research facilities aim for developi
