This paper reports a multi-block unstructured method for incompressible flows and the performance comparison with a multi-block structured method. The unstructured collocated grid is composed of arbitrary cell shapes. Pressure and velocity are stored at cell centres; Rhie and Chow interpolation is used to prevent checker boarding. The SIMPLE algorithm is used for pressure-velocity coupling. The co
We developed a simple one-step dual-label immunoassay for simultaneous measurement of the free, noncomplexed form of prostate-specific antigen (PSA) and total PSA. The assay is based on time-resolved fluorescence and includes a stable fluorescent chelate of Eu to label a monoclonal antibody (mAb) that detects only free PSA, whereas a second mAb labeled with a fluorescent chelate of Tb provides equ
Economic optimization of the production of ethanol by simultaneous saccharification and fermentation (SSF) requires knowledge about the influence of substrate and enzyme concentration on yield and productivity. Although SSF has been investigated extensively, the optimal conditions for SSF of softwoods have yet not been determined. In this study, SO2-impregnated and steam-pretreated spruce was used
RFID (radio frequency identification) technology is developing at a rapid pace. During the last few years, it has been widely discussed in logistics research, as well as in other scientific fields which also approach and contribute to the development of RFID technology. In both logistics and related fields there are findings regarding RFID technology which influence logistics. However, an overall

This paper reports the implementation of the SIMIND Monte Carlo code on an IBM SP2 distributed memory parallel computer. Basic aspects of running Monte Carlo particle transport calculations on parallel architectures are described. Our parallelization is based on equally partitioning photons among the processors and uses the Message Passing Interface (MPI) library for interprocessor communication a
The development of chronic bronchitis (CB) and chronic obstructive airway disease (COAD) seems to be related to inflammatory changes of airway structure. However, the cause and the exact location and type of these changes resulting in altered airway function are not known. Mucosal inflammation is characterized by the recruitment of granulocytes, macrophages and lymphocytes as well as by the sheddi
In man, the predominant proteins in the seminal plasma include semenogelin I, semenogelin II and b-microseminoprotein (MSP). Semenogelin I and II are both synthesized in the seminal vesicles and are the backbone of the gel formed upon semen coagulation. MSP is synthesized in the prostate, but its role has not yet been defined. The genes and cDNA of semenogelin I and II and of MSP were cloned and c
The purpose of this study is an understanding of operator work in a production line and its connection and translation into simulation. A mapping of operator work in the production line was performed, after which tasks and were analysed for their relevance for simulation. A model draft was developed in the software FlexSim. The mapping and the derived model provides insight into operator work in t

The endemic mesosaurid reptiles of the Whitehill-Irati sea in southern Africa and South America during the Permian were studied with preference for the Namibian material. To date three valid mesosaurid species have been described of which two occur on both continents. These mesosaurid aquatic reptiles were among the first evidence used to support the theory of continental drift at the beginning of
Inhemsk mikroalg skapar hållbarhet genom kombination av produktion och vattenrening Genom att använda snabbväxande mikroalger i avloppsvatten för produktion av biomassa har vattnet renats och det enda som tillsätts är solljus och koldioxid. Denna metod möjliggör hållbar produktion av en rad produkter, däribland biobränslen, samtidigt som samhällstjänster såsom vatten- och luftrening utförs på köpAbstract A few local microalgae was isolated and cultivated in vertical column with artificial lighting in 12 h light cycles in wastewater at the local wastewater treatment plant. The growth of the algae strains was observed and the fastest growing (Scenedesmus sp.) was subsequently cultivated outdoors under natural sunlight. pH controlled CO2 input resulted in up to twice as high biomass product
The European Union (EU) and the United States (US) often use different foreign policy strategies. In their non-proliferation policies they have had somewhat different approaches towards the suspected proliferators. In this thesis the usefulness and effectiveness of these different strategies, containment and engagement, are studied within the question of non-proliferation of Weapons of Mass Destr
In this paper the trade of virtual items in online games for hard currency is analysed using economic theory. There are real welfare gains from trade but the game designer’s interests must be taken into account when deciding whether trade is desirable or not. Ricardo's Comparative Advantage and Hecksher-Ohlin Factor Proportion theories lead to conclusions about game design when trade is free.
Nanoteknik är ‘big business’. Stora summor pengar står på spel då detta innovativa teknikområde expanderar i snabb takt. Denna undersökning utgår från antagandet att ekonomiska intressen snarare än demokratiska värden och hållbar utveckling styr utvecklingen av nanoteknik i Sverige idag. Detta ses som problematiskt, och det övergripande målet är att föreslå alternativa principer för att styra utveNanotechnology is big business. With rapid innovation and expansion of the field, financial stakes are high. This study is based on the assumption that the development of nanotechnology in Sweden today is controlled by economic interests rather than democratic values and sustainable development. This is considered problematic, and the overall aim with this study is to propose alternative principle
A considerable part of world merchandise is transported by sea, and with about 150,000 crew members working on the ship types of interest for this thesis there is much at stake if an accident occurs, both with respect to human lives and financial losses. Since fires have previously shown to be responsible for many accidents with severe consequences, the aim of this thesis has been to investigate t
