Pathogenesis of infections related to foreign devices within the cerebral ventricles

Popular Abstract in Swedish Vid det tillstånd som kallas för vattenskalle, hydrocephalus, uppstår övertryck innanför skallen på grund av att vätskan, som cirkulerar där inte kan dräneras. Redan efter andra världskriget började man sätta in shuntar för att avleda överskottsvätskan till andra hålrum i kroppen, hjärtats förmak eller bukhålan. Runt 1960 kom emellertid de första rapporterna om infektioCoagulase-negative staphyloccoci (CoNS) are the most frequently isolated micro-organisms from infected cerebrospinal fluid (CSF) shunts and temporary ventricular drainage catheters, used in modern neurosurgery. CoNS originate from the skinflora of the patient or the surgeon and gain access to the surface of the implant at the insertion, but the infection can erupt up to a year later or more. Immed

Optical parametric oscillator based lidar system applied to atomic mercury monitoring

Field measurements of mercury emissions has been performed by using a mobile lidar system. In this system an Nd:YAG-pumped OPO (Optical Parametric Oscillator) laser system is employed to generate a narrow band (better than 0.2 cm-1) UV beam at the mercury resonance absorption line at 253.65 nm. An inter-comparison of the lidar system and two different point monitoring systems has been p

Stora döden. Den värsta katastrof som drabbat Europa

Boken handlar om digerdöden 1347-52 och dess kulturella följdverkningar, främst i Europa (men även i Främre Orienten). Steg för steg skildras epidemins härjningar i hela den kända världen, men dessutom skildras dåtidens orsaksförklaringar, medicinska experiment, religiösa rörelser, judepogromer, agrarkriser, med mera, vilka alla på ett eller annat sätt kan länkas till digerdöden. Boken belönades

Conference • NNHSH 2014 Theme: Creative and able citizens: managing health and illness during the life course

As the Nordic welfare states evolve – with ideologies that focus on an increased consumption of health services – citizens are required to be productive throughout their life course. And because fewer economic resources are being invested into basic health care, and there is a move to shift more responsibility onto the individual (patient), it is becoming essential to illuminate practices that sho

Isomorphism, Isopraxism and Isonymism: Complementary or Competing Processes?

New institutional theory has been critizised, for describing institutionalization as a static qualitative state rather than a process. In this paper we provide an extended understanding of the process of institutionalization by replacing the mechanical concept of diffusion by the concept of translation and an analytical model of "trevel of ideas". Analyzing the field material from three cases of t

Upper Extremity Disorders - Epidemiology and Measures of Disability

The aim of this thesis was to investigate the prevalence and characteristics of long-lasting upper extremity symptoms in a general population and to study some methodological aspects of outcome assessment and reporting, including validation of a Swedish version of an upper extremity region-specific outcome instrument that potentially could be useful for assessing upper extremity disorders. A gener

Evaluation of the Communications Performance Achievable on Base Station to Handheld-Terminal Radio Links with Several Different Practical Receive Antenna Arrays

In this paper, the information extracted from Single-Input Multiple-Output sounding measurements is used to study the effect of several aspects of the receive antenna arrays on system performance. The extracted multipath parameters are used to synthesize the MIMO channel matrices of a hypothesized communication system having a fixed microcellular base-station and a handheld terminal moving through

Optical studies of single quantum dots in microdisks

Microdisks containing single, selected self-assembled quantum dots were fabricated and their optical properties were studied. Using two electron beam lithography exposures, the dots were positioned at the microdisks edges where the optical field reaches its maximum with sub-micron precision. High Q-values, in excess of 13000 were achieved and the coupling of the emission from single quantum dots t
