Popular Abstract in Swedish I den här doktorsavhandlingen presenteras ett datorprogram som utvecklats för att simulera och utvärdera biotekniska processer, där flera processteg kan vara integrerade. Speciellt har en process för framställning av mjölksyra från vetemjöl studerats. Mjölksyra har traditionellt använts i kemi-, läkemedels- och livsmedelsindustrin som t.ex. råvara, surgörare eller konseBiotechnical processes are often integrated to increase productivity and yield. It is difficult to predict the effects of process integration and to find optimum conditions for the process. A valuable tool for the evaluation of a complete process is mathematical modelling. In this thesis, a computer program developed for simulation and optimisation of integrated biotechnical processes is presented

Many economic models contain the single variable 'money'. Money does not exist in the form of a single physical unit and it is common to construct monetary aggregates using the method of simple summations. Monetary aggregation theory lends little or no support to the method of simply summing various monetary asset components up to arbitrary levels of aggregation. In monetary aggregation theory, mo

Platform development provides software organisations with means to quickly respond to changing consumer needs. Product reuse and improved development efficiency can be achieved if platform development is introduced. A major challenge when using software platforms to produce a variety of products is to keep a high quality of the platform throughout the development of the products. It is therefore

1. The spontaneous mechanical activity of guinea-pig mesotubarium consists of fused tetanic contractions lasting about 6 min, with a frequency of about four per hour. The muscle is completely relaxed between the contractions. Stretching the relaxed muscle elicits a contraction of the same appearance as the spontaneous ones. Comparison of preparations from oestrus (day 1 of the hormonal cycle), dio

Background: Treatment decisions can be difficult in men with low-risk prostate cancer (PCa). Objective: To evaluate the ability of a panel of four kallikrein markers in blood-total prostate-specific antigen (PSA), free PSA, intact PSA, and kallikrein-related peptidase 2-to distinguish between pathologically insignificant and aggressive disease on pathologic examination of radical prostatectomy (RP

Context: Due to the complexity and challenging nature of radical prostatectomy (RP), it is likely that both short-and long-term outcomes strongly depend on the cumulative number of cases performed by the surgeon as well as by the hospital. Objective: To review systematically the association between hospital and surgeon volume and perioperative, oncologic, and functional outcomes after RP. Evidence

Modern societies' functionality is strongly dependent on the electricity. Efficient, environment friendly, and economical power production has been in focus for a long time. The introduction of computers and thereby computer-aided tools for pre-design studies, optimization and choice of the best operational strategies, has changed the conditions for power production tremendously. The most noticeab

Diamond-Blackfan anemia (DBA) is a congenital red cell aplasia in which 25% of the patients have a mutation in the ribosomal protein (RP) S19 gene. It is not known how the RPS19 deficiency impairs erythropoiesis and proliferation of hematopoietic progenitors. To elucidate molecular mechanisms in RPS19 deficient DBA, we analyzed the effects of RPS19 deficiency on EPO induced signal transduction, ce

The aim of this study was to investigate healthcare utilization patterns over a six-year period among older people (60+), classified as dependent/independent in Activities of Daily Living (ADL) and/or at/not at risk of depression and to identify healthcare utilization predictors. A sample (n=1402) comprising ten age cohorts aged between 60 and 96 years was drawn from the Swedish National study on

Background: Overdiagnosis and subsequent overtreatment are important side effects of screening for, and early detection of, prostate cancer (PCa). Active surveillance (AS) is of growing interest as an alternative to radical treatment of low-risk PCa. Objective: To update our experience in the largest worldwide prospective AS cohort. Design, setting, and participants: Eligible patients had clinical

Background: Evolutionary biologists are often misled by convergence of morphology and this has been common in the study of bird evolution. However, the use of molecular data sets have their own problems and phylogenies based on short DNA sequences have the potential to mislead us too. The relationships among clades and timing of the evolution of modern birds (Neoaves) has not yet been well resolve

The dissertation can be divided into two parts, the first of which is a detailed analysis of three excavations concerning Mellanbyn in southern Malmö. In the second part I study the more general development of society, relating Mellanbyn to the surrounding area as well as to the region as a whole during Late Bronze Age and the Early Iron Age. The aim can be summed up as being to study the developm

Identifying the genes that underlie phenotypic variation in natural populations, and assessing the consequences of polymorphisms at these loci for individual fitness are major objectives in evolutionary biology. Yet, with the exception of a few success stories, little progress has been made, and our understanding of the link between genotype and phenotype is still in its infancy. For example, alth

The X chromosome (chrX) represents one potential source for the "missing heritability" for complex phenotypes, which thus far has remained underanalyzed in genome-wide association studies (GWAS). Here we demonstrate the benefits of including chrX in GWAS by assessing the contribution of 404,862 chrX SNPs to levels of twelve commonly studied cardiometabolic and anthropometric traits in 19,697 Finni

Raised blood pressure (BP) is a major risk factor for cardiovascular disease. Previous studies have identified 47 distinct genetic variants robustly associated with BP, but collectively these explain only a few percent of the heritability for BP phenotypes. To find additional BP loci, we used a bespoke gene-centric array to genotype an independent discovery sample of 25,118 individuals that combin

Local environmental and ecological conditions are commonly expected to result in local adaptation, although there are few examples of variation in phenotypic selection across continent-wide spatial scales. We collected standardized data on selection with respect to the highly variable plumage coloration of pied flycatcher (Ficedula hypoleucaPall.) males from 17 populations across the species' bree

Background Multiple myeloma cells uniformly overexpress CD38. We studied daratumumab, a CD38-targeting, human IgG1κ monoclonal antibody, in a phase 1-2 trial involving patients with relapsed myeloma or relapsed myeloma that was refractory to two or more prior lines of therapy. Methods In part 1, the dose-escalation phase, we administered daratumumab at doses of 0.005 to 24 mg per kilogram of body

This thesis concerns the prediction of the fluid mechanical conditions in some specific large vessels in the human body. Large vessels are special in the way that the Reynolds number is relatively high and in the case of arteries the flow is pulsatile. The aim is to contribute to the knowledge of flow patterns in large vessels, and ways to predict and measure fluid mechanical parameters such as sh
