Den här avhandlingen handlar om luftburna designade nanopartiklar och hur mantar reda på vilka egenskaper de har. Luftburna partiklar eller aerosoler är något sommänniskan alltid har haft omkring sig. Oavsett om det varit i form av pollen, rök fråneldstaden, eller från astmainhalatorn så har de alltid varit där och påverkat oss. I varjeandetag drar vi in flera tusen partiklar, men vilken typ de är

We have fabricated a silicon-glass two-phase droplet microfluidic system capable of generating sub 100 μm-sized, ø = (74 ± 2) μm, spherical droplets at rates of up to hundreds of hertz. By implementing a two-dimensional (2D) acoustophoresis particle-positioning method, we show a fourfold improvement in both vertical and lateral particle positioning inside the droplets compared to unactuated operat

The measurement of azimuthal correlations of charged particles is presented for Pb-Pb collisions at sNN=2.76 TeV and p-Pb collisions at sNN=5.02 TeV with the ALICE detector at the CERN Large Hadron Collider. These correlations are measured for the second, third and fourth order flow vector in the pseudorapidity region |η| < 0.8 as a function of centrality and transverse momentum pT using two obser

The financial position of the medical insurance system of Japanese government has been worsened recently, and thus the Ministry of Health, Labor and Welfare has prompted the medical reforms to reconstruct the financial balance of the medical insurance system. As one of these efforts, a fixed payment system for medical services based on “DPC” (Diagnosis Procedure Combination) was introduced to a nu

After the first description of the inherited nature of bimodal deaf-blindness disease in mid nineteenth century by pioneering ophthalmologists Albrecht von Graefe (May 22, 1828 ± July 20, 1870) and Richard Liebreich (June 30, 1830 - January 19, 1917) followed by its confirmation in early twentieth century from a larger number of patients by another pioneer ophthalmologist Charles Howard Usher (Mar

Apolipoprotein A-I (apoA-I) is the major protein constituent of high density lipoprotein (HDL) and plays a central role in phospholipid and cholesterol metabolism. This 243-residue long protein is remarkably flexible and assumes numerous lipid-dependent conformations. Consequently, definitive structural determination of lipid-free apoA-I in solution has been difficult. Using electron paramagnetic

Our perception of time varies considerably from moment to moment, but how this variability relates to endogenous fluctuations in attentional states has been neglected. Here, we tested the hypothesis that perceptual decoupling during spontaneous mind wandering episodes distorts interval timing. In two studies with different visual subsecond interval timing paradigms, participants judged their atten

We develop a mesoscopic field theory for the collective nonequilibrium dynamics of multicomponent mixtures of interacting active (i.e., motile) and passive (i.e., nonmotile) colloidal particles with isometric shape in two spatial dimensions. By a stability analysis of the field theory, we obtain equations for the spinodal that describes the onset of a motility-induced instability leading to cluste

The lack of in vitro prostate cancer models that recapitulate the diversity of human prostate cancer has hampered progress in understanding disease pathogenesis and therapy response. Using a 3D organoid system, we report success in long-term culture of prostate cancer from biopsy specimens and circulating tumor cells. The first seven fully characterized organoid lines recapitulate the molecular di

The digital cellular systems era started about thirty years ago with the release of the first digital cellphones. These first digital cellphones were very different from today’s slim and esthetic cellular pocket computers. They were not mass-produced in million units a day, and they were designed for radio performance rather than appearance. Today, all components are integrated inside the mobile p

This study investigated whether more patients with contact allergies were detected by patch testing with mercapto mix with a higher concentration of 2-mercaptobenzothiazolinone (MBT) than the commonly used mercapto mix. A total of 3,143 dermatitis patients in 5 Swedish dermatology departments were patch- tested with 3 mercapto test preparations: MBT 2.0% petrolatum (pet.); mercapto mix 2.0% pet.;

This article historicises the nature of political transition in Myanmar to better appreciate the challenges faced by civil society. After Myanmar’s political reforms in 2011, Western donors rushed into the country in support of what they misunderstood as a remarkable instance of democratisation. In 2019, escalating civil war, ethnic cleansing, and contracting civil liberties urge a rethink. This a

Platelets express Toll-like receptor 4 (TLR4), and this has been shown to be responsible for the thrombocytopenia induced by lipopolysaccharide (LPS) administration in vivo. We studied the role of LPS in mediating platelet phagocytosis by THP-1 cells in vitro by flow cytometry. Opsonization of platelets with an IgG monoclonal (W6/32) antibody or with IgG autoantibody-positive sera from patients wi
