We present a flexible and efficient program package written in C++, PROFASI, for simulating protein folding and aggregation. The systems are modeled using an all-atom description of the protein chains with only torsional degrees of freedom, and implicit water. The program package has a modular structure that makes the interaction potential easy to modify. The currently implemented potential is abl
This thesis concerns two interrelated subjects of heat and mass transfer processes. The first one concerns mainly experimental measurements, with a subsequent development of a calculation procedure, of the thermal and hydraulic performances, experimental methods and evaluation procedures applied on various plate heat exchangers (PHEs) as evaporators with the refrigerant ammonia as working medium.
Women are a neglected group for cardiovascular disease. Whereas young women tend to have lower incidences of coronary artery disease, stroke and myocardial infarctions than men, the situation changes drastically at menopause, after which women are at greater risk than men. Despite this, women at all ages receive less treatment, less attention and not enough information about health risks. Most ris
We propose a new third-order multidimensional upwind algorithm for the solution of the flow equations on tetrahedral cells unstructured grids. This algorithm has a compact stencil (cell-based computations) and uses a finite element idea when computing the residual over the cell to achieve its third-order (spatial) accuracy. The construction of the new scheme is presented. The asymptotic accuracy f
Particle separation is one of the fundamental processes in wastewater treatment and a good understanding of the basic separation mechanisms ? sedimentation, flotation and filtration ? is critical in the design of wastewater treatment systems. Upgrading of treatment plants for enhanced primary treatment and effluent polishing are current examples of applications where effective, high-rate separatio
Thromboembolic complications during pregnancy are major contributors to maternal death, but there is no reliable way to estimate the absolute risk of thrombosis before the occurrence of a thromboembolic complication. OBJECTIVE: To create a model for individual estimation of thrombosis risk during pregnancy and to determine the distribution of risk estimates in a series of gravidae. METHOD AND PATI
Due to the ongoing urbanisation, the urban environment will consist of extended impervious areas, such as roof tops, roads and parking lots. During rainfall events these kinds of impermeable areas will cause a faster and larger response in runoff, which can lead to an increased load on the storm-water system and thus increase the risk of flooding. In certain areas, the situation will be further wo
There have been several studies which indicate a preferential invasion towards younger red blood cells (RBCs) for the malarial parasite, P. Falciparum. Knowledge about a preferential mechanism could aid in the development of novel anti-malarial drugs. While the preference in these reports has been studied with density-separation of red blood cells, separating the cells by deformability may be a mo
It is said that coreference is difficult to explain, but easy to comprehend; everyoneknows coreference, they just don’t know that they do. We trained a computer toknow it too! Coreference resolution is the identification of phrases that refer to the same entity in a text. Current techniques to solve coreferences use machine-learning algorithms, which require large annotated data sets. Such annota
The constantly increasing awareness of protecting the environment has put electrical roads in the spotlight as an alternative solution to fossil driven means of transport. Dan Zethraeus has developed an innovative idea for a prototype electrical road which conductively supplies power to the cars whilst driving. The concept is to place a line of short rail segments in the middle of the drive lanes

The purpose of this master thesis project was to compare two pasteurizers (pasteurizer 31 and 52) at Österlenmejeriet AB (ÖMAB) in Lunnarp, which is a part of Danone, France and once the differences were clear the goal was to have them equalized in the aspect of heating effects/temperature treatments/heating load and processing parameters. The products that are mainly pasteurized on these pasteuri
We present a software solution that enables faster and more accurate data analysis of 2DE/MALDI TOF MS data. The software supports data analysis through a number of automated data selection functions and advanced graphical tools. Once protein identities are determined using MALDI TOF MS, automated data retrieval from online databases provides biological information. The software, called 2DDB, redu
A set of simple analytical equations, derived from the Flory-Huggins theory, are used to identify the dominant driving forces for phase separation and solute (e.g., protein) partitioning, in the absence and presence of added electrolyte, in every general class of aqueous two-phase systems. The resulting model appears to capture the basic nature of two-phase systems and all trends observed experime
Computer generated imagery is used in a wide range of disciplines, each with different requirements. As an example, real-time applications such as computer games have completely different restrictions and demands than offline rendering of feature films. A game has to render quickly using only limited resources, yet present visually adequate images. Film and visual effects rendering may not have st
The recent progress in our work to implement salt (NaCl) as a dosemeter is presented. Laboratory investigations have indicated a linear dose response from 1 mGy to about 100 mGy and detection limits down to 0.1 mGy. Investigations in the clinic comparing TL-dosimetry in LiF and OSL in NaCl have indicated a similar dose response for the two dosemeters at different photon energies. Field studies wit
Cold sensitivity is a common and persistent complaint after various hand injuries and diseases. The general aim of the thesis was to investigate the consequences of cold sensitivity for daily life in patients with traumatic hand injuries and hand-arm vibration syndrome (HAVS). To obtain a richer and more comprehensive picture reflecting the aim, studies with a quantitative and a qualitative design
