The main purpose of this thesis was to examine various factors influencing starch retrogradation. The reassociation events of starch, which are closely linked to the staling of bakery products, were mainly studied by thermal analysis. Some aspects of starch gelatinization are also included. The gelatinization and retrogradation were described as non-equilibrium processes where the phase transition
There is a crisis discussed in the discipline of Information Systems. Those who perceive such a crisis to exist are by no means agreed, as to its nature and origins. Our inquiry shows that there are a three distinct ‘crises’ being debated. The first of these relates to the substance and boundaries of the discipline itself and if it is even a discipline at all. Another ‘crisis’ relates to higher ed
The desert locust, Schistocerca gregaria, is a polymorphic insect that occurs in two morphological and physiological distinct phases, solitary and gregarious, depending on population density. The two phases are reversible at any developmental stage. The gregarious phase produces and uses stage-specific pheromones, that keep the swarm together. In my thesis, I investigated the functional morphology
Because of deflections under load, contacts on tooth flanks can occur outside the theoretical plane of action between non-conjugated profiles especially when tooth modifications are not appropriate. The main objective of the present paper is to introduce an original model of the dynamic behavior of spur gears when submitted to these particular meshing conditions. The pinion and the gear of the pai
I Skåne kan klimatförändringarna förbättra förutsättningarna för produktion av grödor och annan biomassa via förlängd växtsäsong och ökad tillväxt. Samtidigt ökar dock risker för skador, sjukdomar och insektsangrepp. En intensifiering av jordbruk för att ta vara på ökad produktionspotential och för att möta ett ökat behov av biomassa riskerar att förvärra problem som redan finns när det gäller fö

Popular Abstract in Swedish Muskulaturen i livmoderns vägg har en uttalad förmåga att dra ihop sig och dessa muskelkontraktioner spelar stor roll vid olika fysiologiska processer t.ex. vid befruktningen och för transport av ägg och spermier. Kontraktionerna i livmodern under förlossning är smärtsamma och benämns följaktligen "värkar". Vid menstruationssmärta är sammandragningar i livmodern också aWith a view to the aetiology and treatment of preterm labour and primary dysmenorrhoea we studied the influence of sexual steroids on the plasma levels of oxytocin and vasopressin, effect of these peptides on uterine contractility in vitro and in vivo, receptor concentrations and antagonists to oxytocin and vasopressin. In postmenopausal women oestrogen increased the concentrations in plasma of bo
This thesis examines the links developing between the universities and their regions in the globalising knowledge economy as observed in the UK. It examines institutional responses to two realms of policies, namely, higher education policy and regional development policy. The diversifying missions of universities, especially, the ‘third stream activities’ promoted by the UK government since the la
Bröderna Ernst och Friedrich Georg Jünger var samtidsvittnen som iakttog, uttydde och kommenterade 1900-talet i dess olika faser och händelseförlopp. Bådas liv och verk utgör i hög grad en löpande kommentar till det gångna århundradet.
Jet engine noise is an environmental problem that needs to be addressed. Several methods to reduce the jet noise have been proposed in the last decades. The main issue is to find methods that reduce noise without causing considerable loss of thrust. Experimental and computational tools are mandatory in successfully reducing jet engine noise emissions. One of the challenging issues of computing the
