We present joint experimental and theoretical investigations of the deep-ultraviolet Raman scattering spectra of monolayer graphene thin films. We found that upon a 266 nm laser excitation, while the G mode remains pronounced, the mode is not observed. The mode exhibits distinctive linewidth broadening towards the ultraviolet frequency region. The peak intensity ratio of the and G modes increases

Purpose: To study the impact of corneal guttata on postoperative visual acuity and patients’ self-assessed visual function after cataract surgery. Setting: Patient data from 49 Swedish cataract surgery units. Design: Retrospective cross-sectional register-based study. Methods: Data from patients who had cataract surgery from 2010 to 2017 and completed the Catquest-9SF questionnaire were obtained f

The present paper deals with the time - dependent rock deformation during tunnelling, and more particularly, its association with the related phenomenon of creep in its viscoelastic form, as well as the numerical evaluation of it. Initially, a brief introduction of these two phenomena is provided. Then, the Burgers' idealized model of rheological rock mass behaviour is presented and analysed, alon

Gold nanoparticles are of great interest for various nanoelectronic applications, e.g., for making single electron transistors or very fine leads to molecular size entities. For this and other applications, it is important that all particles have controllable size and shape. In this paper, we describe the production of size-selected gold aerosol particles in the 20 nm range made by evaporation in

Laminar burning velocities of syngas/air premixed flames, varying with H2/CO ratio (from 5/95 to 75/25) and N2 or CO2 dilution rate (from 0% to 60%), were accurately measured using a Teflon coated Heat Flux burner and OH-PLIF based Bunsen flame method. Experiments were carried out at atmospheric pressure and room temperature, with fuel/air equivalence ratios ranging from fuel-lean to fuel-rich. Co

Background: An increasing proportion of physicians are women, yet they still face challenges with career advancement. In 2014, the European Stroke Organisation established the goal of increasing the number and participation of women within the society using a Top Down and Bottom Up approach. The ‘Women’s Initiative for Stroke in Europe’ was created the same year by a group of women active within t

Nucleate pool boiling performance of two well-wetting liquids, i.e., acetone and HFE7200, on three nanoparticle-coatedsurfaces were experimentally studied and compared with that of the smoothsurface. Electrophoretic deposition was used to fabricate nano-porous surfaces.Surface roughness, static and advancing contact angles, capillarity of the smoothand coated surfaces were characterized. Compared

Hyperdiploidy, i.e. gain of whole chromosomes, is one of the most common genetic features of childhood acute lymphoblastic leukemia (ALL), but its pathogenetic impact is poorly understood. Here, we report a proteogenomic analysis on matched datasets from genomic profiling, RNA-sequencing, and mass spectrometry-based analysis of >8,000 genes and proteins as well as Hi-C of primary patient samples f

Objectives: Measurement of lactate in fetal blood is used to assess the degree of anaerobic metabolism. The technical difficulties in obtaining enough scalp blood for analysis by a bloodgas-analyzer advocates for the use of a point-of-care device. StatStrip®Xpress™ (SSX) has shown promising properties but needs further evaluation before implementation into fetal surveillance. Methods: Arterial/ve

Flera studier har på senare år visat att den läkare som själv blir sjuk upplever sig försatt i en särskilt problematisk situation. Ett sätt att öka förståelsen för den sjukdomsdrabbade läkarens upplevda dilemma kan vara att närstudera läkares sjukdomsnarrativ. I denna artikel uttolkas tre skriftliga vittnesmål av läkare med morfinmissbruk, med särskild tonvikt på Michail Bulgakovs semifiktiva nove

Multiplex separation of mixed cell samples is required in a variety of clinical and research applications. Herein, we present an acoustic microchip with multiple outlets and integrated pre-alignment channel to enable high performance and label-free separation of three different cell or particle fractions simultaneously at high sample throughput. By implementing a new cooling system for rigorous t
