Laplace distribution models for road topography and roughness

Gaussian models are frequently used for road profiles. However, these models are often only valid for short sections of the road. Here we present a comprehensive approach to describe various aspects of road surface/elevation by using extensions of Gaussian models arising from random gamma distributed variances. These random variances result in the Laplace distribution and thus we refer to the so d

Aggressive lymphoma

Popular Abstract in Swedish Aggressiva lymfom utgör en undergrupp av en typ av elakartade (maligna) tumörer, maligna lymfom. Cellerna i dessa tumörer utgår från en typ av vita blodkroppar, lymfocyter, vilka har en central roll i kroppens immunförsvar. Maligna lymfom utgör ca 4% av alla fall av elakartade tumörer i Sverige, vilket motsvarar ca 1700 nya fall per år. I västvärlden ökar dock antalet fAggressive lymphoma is a rapidly growing tumour of lymphocyte origin, potentially curable with chemotherapy. In a trial by the Nordic Lymphoma Group, 405 patients with aggressive lymphoma were included, and randomised to receive either the standard chemotherapy regimen, CHOP, or a weekly multidrug regimen, MACOP-B. In this trial, MACOP-B was not superior in terms of response, failure-free or overa

Variation of Elemental Composition with Particle Size in the St. Louis Aerosol

Detailed particle size distribution of elemental constituents have been determined in the St. Louis aerosol by sampling with cascade impactors for particles >0.25 μm aerodynamic diameter and by analyzing using proton-induced X-ray emission, PIXE, for S, Cl, K, Ca, Ti, Mn, Fe, Zn, Br, and Pb. Two rooftop sites were selected for intensive sampling in industrial and residential locations in St. Louis

Deterministic Java in tiny embedded systems

As embedded systems become more and more complex, and the time to market becomes shorter, there is a need in the embedded systems community to find better programming languages that let the programmers develop correct code faster. The programming languages used today, typically C and/or Assemblers, are just too error-prone. The Java technology has therefore gained a lot of interest from developers

Broken technologies : the humanist as engineer. Updated November 2015

There are many possible definitions of “technology” and I will discuss some of these in this book. However, in this introduction let me use a definition of Svante Lindqvist who defines technology very intuitively as “those activities, directed towards the satisfaction of human wants, which produce change in the material world.” He says also “the distinction between human “wants” and more limited h

Färg, ljus och människa. Ett miljöpsykologiskt perspektiv

Under livets utveckling på jorden har solljuset med sitt karakteristiska spektrum och sin dygnsvariation haft en avgörande betydelse, t ex att vi har olika hudfärg, att vi blir solbrända, att vi har en 24-timmars dygnsrytm. Detta behandlas under rubrikerna Solljusets inverkan på huden; Årstidsrelaterad nedstämdhet; Skiftarbete och arbete under jord; Belysningsplanering för bättre hälsa; Färgsättni

Fungal cellulases: Study of hydrolytic properties of endoglucanases from Trichoderma reesei and Humicola insolens

Cellulose is one of the most abundant biopolymers on earth. Several organisms degrade cellulose, one of the most studied is the fungus Trichoderma reesei which produces seven genetically different cellulases. In this thesis, a thorough study of the hydrolytic characteristics of the less studied endoglucanases Cel12A (EG III), Cel45A (EG V) and Cel61A (EG IV) of T. reesei is presented. Cel12A showe
