Ultra-short X-ray pulses are generated by focusing 150 fs laser pulses with an energy of 200 mJ onto metal targets. Focal intensities are expected to reach 1018 WI cm2• An efficient X-ray source has been developed. This X-ray source has been characterised, with an emphasis on photon energies above 10 keV. Measurements of the spectral distribution of X-rays, the overall X-ray yield and the spatial

The subject of the thesis is intericonicity, i.e. the relations between iconic signs. Hypothetically we only have a tacit knowledge of interikonicity, and the aim of the thesis is to establish a theory about it, grounded in hermeneutics and semiotics. According to this Theory of Intericonicity all representations, all iconic signs, are fascinated, rhetorical transformations of models. Paraphrase a

Objective: Hypoxic-ischemic encephalopathy (HIE) is one of the major causes of perinatal mortality and morbidity. To date, there are no reliable methods to detect which infants will develop brain damage after asphyxia insult. Design and Setting: Prospective study conducted in three tertiary departments of neonatology from December 1999 to July 2002. Participants: A total of 44 infants with perinat

Popular Abstract in Swedish Olika laserbaserade mätmetoder för diagnostik av förbränningsmotorrelaterade fenomen har utvecklats och demonstrerats, såväl utanför som i motorer. Följande områden har studerats: -Inverkan av inhomogen bränsle-/luftblandning på cykel-till-cykelvariationer hos förbränningen i en otto-motor studerad genom laserinducerad fluorescens (LIF) på bränslet. -Restgasers inverkanVarious laser diagnostic techniques have been developed and demonstrated for engine, or engine-related measurements. The experimental work is presented in Chapter 3 and in Papers I-VII. In Chapter 3, imaging of soot in a running compression-ignition (CI) is described. Four different approaches were applied with the aim of investigating the applicability of these approaches in a running engine. I

OBJECTIVES: To explore the development of hypertension (HT) in a cohort of young middle-aged men. DESIGN: Prospective birth-cohort study of men surveyed over 6 years. SETTING: Helsingborg County Hospital, Sweden, 1990-97. SUBJECTS: A total of 628 men born in 1953-54, all surveyed at 37, 40 and 43 years of age. MAIN OUTCOME MEASURES: Systolic blood pressure (SBP), diastolic blood pressure (DBP), S-

OBJECTIVE: To compare the outcome of patients operated on acutely for ruptured abdominal aortic aneurysms (AAA) or otherwise symptomatic aortic aneurysms in a university hospital and in two county hospitals by the same group of vascular surgeons. DESIGN: Retrospective study. SETTING: 1 university and 2 county hospitals, Sweden. SUBJECTS: 108 patients operated on urgently for AAA, 81 at the univers

Objectives. To study changes in: (i) the prevalence of hormone-replacement therapy (HRT) and (ii) women's attitudes and knowledge about the climacteric. Design. Cross-sectional comparison was performed on two populations of women both aged 46-62 years and resident in the same urban Swedish population over a period of 6 years. Materials and Methods. In 1992, a random sample of 5990 women, from five

Background: Rat models of peritoneal dialysis (PD) are useful for studying the physiology of peritoneal transport and evaluating new osmotic agents. Intraperitoneal (IP) solute concentrations and their evolution over time are easy to measure, but IP volume (IPV) is not. Direct volumetric measurements are the "gold standard;' but they are expensive and do not allow for repetitive measurements in th

The emissions of particles, and gaseous compounds, into the ambient air from biomass-fired moving grate boilers were characterized under different boiler operation conditions. The boilers had a thermal capacity of similar to1 MW. The flue gas cleaning systems consisted of multicyclones for the removal of coarse particles. Dry wood fuel that consisted of shavings, wood chips, and sawdust from a loc
