Glaciärer har visat sig vara känsliga för klimatologiska förändringar i sitt närområde och deras känslighet sträcker sig över flera olika tidsskalor. Glaciärerna har därför kommit att användas som indikatorer på både pågående och förhistoriska klimatförändringar. För att glaciärerna ska kunna spegla klimatet så krävs emellertid tillförlitliga mätmetoder av glaciärernas massa. I avsikt att återge gGlaciers integrate variations in climate over several different time scales and are thus used as indicators of both present and past climate change. It is however of importance to be able to correctly measure changes in the glaciers mass over time (the glaciers mass-balance), if one wishes to use the glaciers as climate indicators. The mass-balance of a glacier is a direct result of the glaciers a

The aim of this thesis is to investigate and evaluate the use of escape filters during the construction phase of tunnels and mines. To achieve this aim three main research methods were used. Firstly, a literature review was produced to evaluate the current research about escape filters and fire safety during the construction phase of tunnels and mines. Secondly, interviews were conducted to find r

Background: Colour differences in photographs can be enhanced using a digital image-processing technique called LYYN. Objective: To investigate colour changes in the histamine wheal after skin prick tests (SPTs). Methods: Histamine SPTs were performed on the forearm of six medical students, and the reactions of the skin were photographed every 2 min for 30 min. Colour differences in the photograph

A large number of disease-causing mutations have been identified from several protein kinases. KinMutBase is a comprehensive knowledge base for human disease-related mutations in protein kinase domains (http://bioinf.uta.fi/KinMutBase/). The latest version contains 582 different mutations for 1,790 cases in 1,322 families. KinMutBase entries are described on the DNA, mRNA, and protein level. Numbe

All scientific research requires problem definition and discipline, as well as concept and method formation. However, from a human point of view the most important problems are probably those found in areas where it may be difficult to provide such ideal research conditions. Rehabilitation engineering and design research is one such field. Nonetheless, we believe that these theory and method forma

Does a rising tide lift all boats? This question – that is, to what extent does improvements of the general economy benefit all – is central to the study of economics and history. From fundamental issues about whether market forces have an innate tendency to increase or decrease differences in economic outcomes, to much debated questions about the effects of government policies, distributional con

Objectives. Surgical sites infections are very expensive and the total costs for coronary artery bypass grafting (CABG) surgery followed by deep sternal wound infection (DSWI) with conventional therapy are estimated to be 2.8 times that for normal, CABG surgery. Promising results have been reported with vacuum-assisted closure (VAC) therapy in patients with DSWI. This study presents the cost of VA

Dialysis patients often suffer from cardiovascular dis- eases, motivating the use of continuous monitoring of car- diac activity in clinical routine. Cardiac pressure pulses propagate through the vascular system and enter the ex- tracorporeal blood circuit of a dialysis machine, where the pulses are captured by pressure sensors. The cardiac pulses are obscured by the much stronger pressure pulses

The activated sludge process is the main process in most urban wastewater treatment systems. It is considered complex in nature, and building its mathematical model in practice becomes difficult. A simple and easy way to build the simulation models for the system is needed. In this paper, a LabVIEW based simulator for the system is presented. LabVIEW offers a highly efficient, simple and flexible
