Popular Abstract in English Low fuel consumption, and reduced exhaust emissions, as well as improved performance and durability become much more important than before for the vehicle industry. These requirements lead to a number of additional equipment installed in the vehicles. All these efforts increase the operating temperature in the engine compartment and reduce the available free space in thCross flow heat exchangers made from aluminum are common as radiators in vehicles. However, due to the increasing power requirement and the limited available space in vehicles, it is extremely difficult to increase the size of heat exchangers (HEXs) placed in the front of vehicles. Placing the heat exchanger on the roof or at the underbody of vehicles might offer opportunity to increase the size o

Systemisk skleros, SSc, är en ovanlig reumatologisk sjukdom där immunologisk aktivering leder till kärlskada och fibros i hud och inre organ. Hälften av patienterna avlider av komplikationer från hjärta eller lungor, ofta fibros i lungor eller pulmonell arteriell hypertension (PAH). Projekten rör kartläggning av tidiga mekanismer kring patogenes och biomarkörer för tidig diagnos och monitorering aSystemic sclerosis, SSc, is a rare rheumatologic disease where immun activation leads to vascular damage and fibrosis in skin and internal organs. Half of the population will die from complications from heart or lungs, mostly lung fibrosis or pulmonary arterial hypertension (PAH). Our projects aim at early pathogenic mechanisms and biomarkers for early diagnosis and to monitor the disease and the

Popular Abstract in English Imagine a solar powered flash light. Each photon absorbed by the flash light’s solar cell creates electric energy and the flash light’s light source converts the electrical energy again into photons. The purpose of such a device may be questionable, because you would be surprised if it would create more light than what it absorbs. However, under certain conditions it isIn this thesis the luminescence properties of highly doped semiconductors are studied with focus on degenerately n-doped InP. It is demonstrated how photoluminescence measurements on degenerately doped semiconductors allow an estimation of the doping concentration without need for electrical contacts. The degenerate doping can furthermore reveal the conduction band structure for energies higher th

Wind-abraded cobbles (ventifacts) and aeolian sand are known from the sandy-gravelly coastal areas of south-western Sweden, especially in association with raised deltas. Ventifacts are recorded on at least two different stratigraphic levels, on top of glaciofluvial sediment and/or on top of littoral deposits, while aeolian sand usually forms a surficial cover. The formation of ventifacts has usual

Sepsis (när en infektion blir livshotande) är en bortglömd folksjukdom som drabbar lika många som cancer och har högre dödlighet än hjärtinfarkt och är mycket dyrt. Sepsis är ett komplext syndrom och borde precis som cancer inte klassas som en sjukdom utan många olika beroende på vilken bakterie som orsakar infektionen, vilket organ infektionen först drabbar och kanske viktigast av allt i vilket iSepsis (when an infection becomes life threatening) is a neglected public health problem affecting as many as cancer, with a higher mortality rate than myocardial infarction and is very expensive. Sepsis is a complex syndrome, akin cancer and should not be classified as a single disease, rather many different depending on 1. the bacteria causing the infection, 2. Organ focus of the infection, and

The invention of computers revolutionized the way of doing science and in particular the field of mathematics. Computers were faster than any human mind in doing calculations and they did not make mistakes opening a wide range of possibilities that earlier where in practice uncomputable. Scientists observe the behavior of nature and find mathematical equations that model the different phenomena. IThe efficient simulation of thermal interaction between fluids and structures is crucial in the design of many industrial products, e.g. turbine blades or rocket nozzles. The main goal of this work is to present a high order time adaptive multirate parallel partitioned coupled method for the efficient numerical solution of two parabolic problems with strong jumps in the material coefficients that
