The problem of finding appropriate probabilities for crossover and mutation with respect to resampling may be addressed using the Markov chain model. Our efforts in this direction lead through a simplification of the mixing matrix incorporating both probabilities. We present the simplification and discuss some of its ramifications. We expect that it may lead to some improvement of the computationa
Popular Abstract in Swedish Denna avhandling utgår ifrån en önskan att finna en växtart som är diploid fakutativ apomikt. En diploid är en organism som, liksom människan, innehåller två kromosomuppsättningar, och en fakultativ apomikt är en växt som sätter frön både sexuellt (med befruktning) och apomiktiskt (utan befruktning). En växt med de begärda egenskaperna skulle ge oss goda möjligheter attFinding a diploid facultative apomictic plant species would give a great opportunity to solve problems concerning the existence and persistence of sexuality and also, it would be a possible source to get a transferable apomictic gene from. The putative diploid facultative apomict Potentilla argentea from southern Sweden was investigated with RAPD, isozymes and flow cytometry. Its mode of reproduct
This article presents in compressed form the development of a psycho-ecological model for simulation of interpersonal relations (SIR). SIR is a method and an instrument, which permits a simulation of strat¬egies of interactive behaviour. From a behavioural science point of view the method should make it possible to map mechanisms that produce and reproduce behaviour. SIR may also be used as an aid
The relation between intra-partum cardiotocography (CTG), cord blood acid-base status, Apgar score and neonatal morbidity was studied in 1228 consecutively live-born babies and in a subgroup of 200 babies (148 babies with a 1 min Apgar score < or = 8 and 52 randomly selected babies with a 1 min Apgar score > or = 9). The scores for the individual components of the 1 min Apgar score were strongly a
Popular Abstract in Swedish Prostaglandiner och tromboxaner är hormonliknande ämnen som består av cykliska fleromättade fettsyror. Karakteristiskt för alla prostaglandiner är att de har en mycket kort halveringstid, de verkar lokalt, kan ej lagras i vävnader och att produktionen hämmas av aspirin (acetylsalicylsyra). Prostacyklin och tromboxan är två prostaglandiner med i stort sett motsatta effekThe fetoplacental circulation is a low pressure system with a high vascular prostacyclin to thromboxane (Pc/Tx)synthesis ratio. In intrauterin growth restriction (IUGR) and diabetes the prostanoid balance may be altered. AIMS: To investigate relationships between umbilicoplacental vascular prostanoid synthesis (by incubation of vessel samples), circulatory changes (by Doppler velocimetry of umbili
The influence of supranational regimes has dramatically increased in the last decades. How this influence is manifested and which consequences it has had and continues to have on education is discussed in this paper. More specifically, the paper highlights lifelong learning and the Bologna process seen as projects, the explicit aims of which starkly contrast to their effects on such vital issues a
The diversity of the contributions to this volume illustrates the complexity of the challenge. Climate change is a governance problem that needs to be analysed, and addressed, at multiple levels, in multiple sectors, and with a view to multiple actors. In searching for policy options that go beyond current negotiations, the contributions thus addressed issues as diverse as international carbon mar
Decisions regarding strategic software process improvement (SPI) are generally based on the management's viewpoint of the situation, and in some cases also the viewpoints of some kind of an SPI group. This may result in strategies, which are not accepted throughout the organisation, as the views of how the process is functioning are different throughout the company. This paper describes a method f
This thesis aims to investigate the dialectics between urban planning and policy on the one hand and economic change and crises in the city of Malmö on the other, with a focus on both the city in general and the specific district of Western Harbour. Malmö provides a (highly) fascinating place to investigate relations between urban and economic change. The city embraced the industrial path longer
Popular Abstract in Swedish Urinvägsinfektion är en av de vanligaste förekommande bakteriella infektioner hos människa och vid 30 års ålder har var femte kvinna någon gång varit drabbad. 80% av alla urinvägsinfektioner orsakas av bakterien Escherichia coli (E. coli). Urinväginfektion kan ge sig till känna i två former. Vid den vanligaste och inte fullt så allvarliga formen, cystit (blåskatarr), ärUrinary tract infection (UTI) is among the most common bacterial infections in humans and the majority are caused by Escherichia coli (E. coli). Abundant evidence indicates that nitric oxide (NO) produced by the inducible NO synthase (iNOS) plays an important role in host defense against infection. This thesis examines iNOS expression in experimental UTI models. The rat and pig bladder urothelium
Innate immunity is important for the integrity of the host against potentially invasive pathogenic microorganisms in the environment. Antibiotic peptides with broad antimicrobial activity are part of the innate immune system. We investigated the presence of the cathelicidin, human cationic antimicrobial protein (hCAP-18), in the male reproductive system. We found strong expression of the hCAP-18 g
This chapter focuses on the description of a pyrolysis model which can be used for implementation within computational fluid dynamics (CFD) codes. The pyrolysis model is available from the literature and includes both thermal heat transfer in the solid phase as well as chemical kinetics. Besides the description of the model, the way how to obtain input parameters is discussed in this chapter and t
