Polycrystalline cubic boron nitride (PCBN) tool materials with NbN binder without additives and PCBN with Al2O3 or Si3N4 micropowder and whisker additives were manufactured and compared. PCBN materials with Si3N4 whisker reinforcement have the best mechanical properties of all the evaluated materials. Composites reinforced with Al2O3 whiskers have the lowest fracture toughness. However, Al2O3 whis

Background: Rituximab (RTX) is approved for remission induction in ANCA associated vasculitis (AAV). However, data on use of RTX in patients with severe renal disease is lacking. Methods: We conducted a retrospective multi-center study to evaluate the efficacy and safety of RTX with glucocorticoids (GC) with and without use of concomitant cyclophosphamide (CYC) for remission induction in patients

The Armed Forces are one of Sweden's largest governmental organizations and at the same time one of Sweden's most gender-segregated and male-dominated workplaces. Recruiting more women into the organization is one of the organization’s main goals for personnel planning, along with providing them with more opportunities for career development. This study sought a deeper understanding of the power rThe Armed Forces are one of Sweden’s largest governmental organizations and at the same time one of Sweden’s most gender-segregated and male-dominated workplaces.

Elevated blood pressure (BP) is a worldwide burden, leading to over 10 million deaths yearly. May Measurement Month (MMM) is a global initiative organized by the International Society of Hypertension aimed at raising awareness of hypertension and the need for BP screening. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in May 2017. BP measurement, the definition of

While pipe biofilms in DWDSs (drinking water distribution systems) are thought to affect the quality of distributed water, studies regarding the microbial processes are impeded by the difficulties in accessing biofilm undisturbed by DWDS maintenance. In this study, pipe sections were removed from a fully operational DWDS for biofilm sampling over two years and three months, and before and after st

The article discusses a tendency towards “media nostalgia” in contemporary experimental literary works.Authors such as Jonathan Safran Foer, Reif Larsen, Anne Carson, Steven Hall, Umberto Eco, J.J. Abramsand Doug Dorst include images, drawing and photographs in their works, or they experiment with the visualand material qualities of writing and the book. The tendency can be explained as a reflecti

Artiklen fokuserer på intermedialitet som erindringsstrategi i nyere litteratur. Fokus er på såkaldte foto-romanerr af Alexander Kluge, W.G. Sebald, Aleksandar Hemon og Jonathan Safran Foer. Med udgangspunkt i W.J.T. Mitchells teori om forholdet mellem ord og billede påpeges en spænding inden for genren: de moderne foto-romaner synes udspændt mellem, på den ene side, en modernistisk tradition, som

Background: Identification of clinical features that might distinguish psychogenic nonepileptic seizures (PNES)from epileptic seizures (ES) is of value for diagnosis, management, and understanding of both conditions. Previousstudies have shown that patients' descriptions of their seizures reflect differences in content and delivery.Weaimed to compare verbal descriptions of PNES and ES using a mixe

In a previous experiment with participants high (Highs) and low (Lows) in hypnotizability,psi z scores had moderate to strong correlations with percipients’ belief of their success and theirprevious ostensible psi experiences, experiencing an Altered State of Consciousness and other alterationsof consciousness during a non-psi ganzfeld session, but only among the Highs. The currentpre-registered s

Riboflavin (vitamin B2) is an important constituent of the prosthetic groups flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), which are utilized as electron-carriers in energy metabolism. Excitation by UV-light leads to the generation of riboflavin radicals and reactive oxygen species (ROS), which can oxidize a wide range of biomolecules. The human protein α1-microglobulin (A1M)

Compared to analogous bulk materials, colloidal nanocrystals have presented a powerful platform for building up electronic devices on the nano/micrometer scale and flexible portable electronic apparatus with the benefits of solution-based processing approach at room temperature. Herein, memristors based on CuInSe2 (CISe) colloidal nanocrystals prepared using a solution-based process at room temper

Vid elektro-pulsbehandling svarar omedelbart bara de celler som utsätts för ett tillräckligt starkt elektriskt fält. De tumörceller som permeabiliseras blir mycket mer tillgängliga för hydrofila molekyler eftersom dessa normalt avvisas av membranbarriären. Anticancermedlet Bleomycin har visat sig vara det mest potenta läkemedlet i elektropulsbehandling och är det som ofta används i elektro-puls-keIn electro-pulse therapy treatment, only the cells exposed to a sufficiently strong electric field will respond immediately. The tumour cells that are permeabilized become much more accessible to hydrophilic molecules since these are normally rejected by the membrane barrier. The anticancer agent Bleomycin has proven to be the most potent drug in electro-pulse therapy and is the one often used in

A controlled pulsed electrical field applied to a living tissue is believed to cause a structural reorganisation in the lipid bilayer of the cell membranes. This electropermeabilisation or electroporation process is used for opening up the cell membrane in order to get access to the cell. An electrical impedance tissue model that incorporates electroporation is presented. From this model a bio-imp

The objective was to investigate if diffusing laser fibres can be modelled as conductive heat sources without miscalculating coagulated volumes, and if finite element analysis, disregarding light transport, may be used for three dimensional (3D) treatment planning in interstitial laser thermotherapy (ILT). Temperature distributions and coagulated volumes with a diffusing laser fibre, as compared t
