We report the observation of neutrons rf:leased from d(d,n) He-3 fusion reactions in the focus of 200 mJ, 160 fs Ti:sapphire laser pulses on a deuterated polyethylene target. Optimizing the fast electron and ion generation by applying a well-defined prepulse led to an average rate of 140 neutrons per shot. Furthermore, the production of a substantial number of MeV gamma rays could be observed. The
Popular Abstract in Swedish Sammanfattning: För religiösa sikher är Guru Granth Sahib en helig skrift som manifester ontologiskt gudomliga och förkroppsligar de historiska guruernas lära och uppenbarelseerfarenheter. Samtidigt har sikherna tagit uppfattningen om en helig skrift längre än någon annan religiös tradition genom att behandla Guru Granth Sahib som en levande guru med både andlig auktoriSummary: For religious Sikhs, the Guru Granth Sahib is a holy scripture which enshrines ontologically divine words and the teaching and revelatory experiences of historical human Gurus. Simultaneously the Sikhs have taken the concept of a sacred scripture much further than any other religious community by treating the Guru Granth Sahib as a living Guru invested with spiritual authority and agency
Hur biomedicinsk forskning populariseras för att anpassa till en bredare allmänhet. Det handlar om att skapa en positiv upplevelse och få allmänhetens gillande för en kontroversiell medicinsk teknik.
The time-dependent orienteering problem is dual to the time-dependent traveling salesman problem. It consists of visiting a maximum number of sites within a given deadline. The traveling time between two sites is in general dependent on the starting time. For ε greater than or equal 0, we provide a (2+ ε)-approximation algorithm for the time-dependent orienteering problem which runs in polynomial
This paper reports a pilot study and three case studies to examine aimed at studying if a quality system, according to the ISO 9000 quality standard, can be visualised, exploring how the visualisation should be designed in order to support continuous improvements and evaluating the design process for development of prototypes. By discussing with the research team, three companies in southern Swede
Objective Skewed gender distribution and falsely assigned gestational age lead to unnecessary or late obstetric intervention in prolonged pregnancy. The aim of this study was to examine the consequences of a fetal gender-dependent systematic 1.5-day dating error at ultrasound fetometry. Material and methods A total of 82484 singleton deliveries greater than or equal to 37 weeks at 11 hospitals in
The rimming flow of condensate in horizontal rotating dryer cylinders has been studied computationally by solving the full Navier-Stokes equations coupled with a volume of fluid method for tracking the free surface. It was shown that significant variations in both condensate velocity and thickness exist at moderate dryer speeds, whereas at higher speeds the variations are of less significance. Reg
In this paper a method for control of air–fuel ratio (AFR) in cold or lean-burning spark-ignited engines is investigated. The technique uses combustion pressure as measured by a cylinder-mounted sensor, and is based on the phenomenon of increasing cycle-to-cycle combustion pressure variation as the air–fuel mixture approaches the limits of flammability. The cylinder pressure is measured from one e
A group of normal subjects (n = 17) was compared with groups of patients with a diagnosis of vestibular neuritis (n = 18), and acoustic neuromas (n = 35). Fisher linear discriminant analysis was applied to distinguish clusters of parameters characteristic for each disease. Hence it was possible to distinguish the vestibular neuritis patients from the normal group with statistical significance (p <
Background & Aims: The COMET trial was a prospective, double-blind, randomised trial comparing carvedilol, a comprehensive adrenergic receptor antagonist, with metoprolol, a beta-1-selective agent in patients with heart failure and left ventricular systolic dysfunction. The trial showed a reduction in mortality with carvedilol that was consistent across subgroups. The purpose of this report is
This paper presents a combination of Reference Attributed Grammars (RAGs) and Circular Attribute Grammars (CAGs). While RAGs allow the direct and easy specification of non-locally dependent information, CAGs allow iterative fixed-point computations to be expressed directly using recursive (circular) equations. We demonstrate how the combined formalism, Circular Reference Attributed Grammars (CRAGs
n the paper three linear aeration controllers that can be easily implemented are presented and evaluated on the activated sludge process pilot plant. Controllers differ according to the information that is used about the process, which can be oxygen in the last aerobic reactor, ammonia in the last aerobic reactor and ammonia in the influent. The aeration controllers that are addressed are: oxygen
X-linked agammaglobulinemia (XLA) is an immunodeficiency caused by mutations in the gene coding for Bruton's tyrosine kinase (BTK). A database (BTKbase) of BTK mutations has been compiled, and its use and the resultant information are discussed in this article.
Let Φ be a symmetric function, nondecreasing on [0,∞) and satisfying a Δ2 growth condition, (X 1,Y 1), (X 2,Y 2),…,(X n ,Y n ) be arbitrary independent random vectors such that for any given i either Y i =X i or Y i is independent of all the other variates. The purpose of this paper is to develop an approximation of valid for any constants {a ij }1≤ i,j≤n , {b i } i =1 n , {c j } j =1 n and d. Our
Popular Abstract in Swedish Man har tidigare sett att patienter med akut myeloisk leukemi (AML) har förhöjda nivåer av det cellcykelreglerande proteinet cyklin A1 och överuttryck av cyklin A1 i de myeloiska cellerna hos transgena möss resulterade i att mössen utvecklade AML. Syftet med avhandlingen var att ytterligare studera uttrycket och regleringen av cyklin A1 i hematopoetiska celler. Vi börjaIncreased expression of the cell cycle regulatory protein cyclin A1 has previously been detected in patients with acute myeloid leukemia (AML) and targeted overexpression of cyclin A1 in a transgenic mouse model initiated AML. The aim of this thesis was to further study the expression and regulation of cyclin A1 in hematopoietic cells. We started with evaluating the subcellular localization of cyc
