Lack of evolutionary potential of developmental instability of front tibia length in the Indian meal moth (Plodia interpunctella)
The evolutionary potential of developmental instability (DI, defined as an individual's inability to buffer its development against random perturbations) as estimated by individual asymmetry (so-called fluctuating asymmetry, small random deviations from perfect symmetry), remains a controversial subject of research. Only if DI is heritable and if it is related with fitness, can evolution be expect
Inbreeding depression in Nigella degenii (Ranunculaceae): Fitness components compared with morphological and phenological characters
We have compared selfed and outbred offspring from individual plants of the annual plant Nigella degenii to examine patterns of inbreeding depression in two direct components of fitness ( flower number and pollen viability) and a number of morphological or phenological characters for which the optimal phenotype may be habitat specific. Selfing lowered flower number, plant height, flower size, and
Faingu City: A modern Mekeo Clan in Papua New Guinea
The thesis is about the historical transformation of Mekeo society. lt is not about the Mekeo as cultural group but about Mekeo society as part of a larger Papuan world of social reproduction. The analysis is anchored in the study of the regional exhange systems which it traces, temporally, through the different historical circumstances influencing the Mekeo area First the pre-colonial regional s
Computer simulation of molecular exchange in colloidal systems
In this paper, we introduce two computer simulation models to study molecular exchange between aggregates in a colloidal dispersion. The Brownian motion of the colloidal aggregates is simulated as a random walk with a Gaussian distributed step length. In model I, the exchanging molecules are simulated as discrete particles with the exchange process characterized by desorption, molecular diffusion,

De GRACILA barnen
GRACILE-syndromet (Fellmans syndrom, MIM 603358) hör till det fi nländska genetiska sjukdomsarvet. Sjukdomen är orsakad av en missens mutation (S78G) i BCS1L, ett protein som fungerar som en “chaperon” eller sammankopplande länk vid bildning av komplex III i andningskedjan. Syndromet uttrycker sig som en grav tillväxthämning redan under fostertiden, och efter födseln utvecklar barnet en uttalad me

Thermodynamics of binding of alpha-cyclodextrin to straight-chain alkyl derivatives in aqueous solution
Apparent standard Gibbs energy, enthalpy, entropy, and heat capacity data of the interactions of alpha-cyclodextrin (alphaCD) to some n-carboxylates H(CH2)(n)COO- (n = 4 - 6), are determined by isothermal titration microcalorimetry at different temperatures in phosphate buffer, pH 9.0, assuming a 1 : 1 model in dilute solution. Modelling of contributions of the thermodynamic properties of the solu
Design and operation of a bench-scale process development unit for the production of ethanol from lignocellulosics
A bench-scale unit for the development of an enzymatic process for the bioconversion of lignocellulosics to ethanol has been used to study the recycling of waste-water streams to minimize fresh-water requirements and reduce effluent streams. Willow, after impregnation with sulphur dioxide, was steam-pretreated, enzymatically hydrolysed, and the sugars produced were fermented using S. cerevisiae. T
Bone allografts pretreated with a bisphosphonate are not resorbed
Bisphosphonates bind to bone surfaces and inactivate osteoclasts when they start to resorb the bone. Therefore, immersion of a bone graft in a bisphosphonate solution before implantation may protect it from resorption. We implanted frozen cancellous; bone allografts; into bilateral bone chambers for 6 weeks in 10 rats. One graft in each pair had been immersed in an alendronate solution (1 mg/mL) f

Comfort and Safety as Perceived by Wheelchair-Seated Bus Passengers
Wheelchair-seated passengers on European and Swedish urban transit buses can travel rearwards, resting against a bulkhead, without the use of tiedown equipment. However, users sometimes disapprove of being the only passengers who have to travel rearwards, and also unrestrained. In order to investigate comfort and safety as perceived by wheelchair-seated bus passengers riding either forwards or rea

En kvinnoröst i manssamhället : Agda Montelius 1850-1920
Popular Abstract in Swedish Syftet med avhandlingen är att belysa det kvinnliga initiativet i den samhällsutveckling som accelererade kring slutet av 1800-talet och så småningom kom att leda fram till det moderna, demokratiska s k välfärdssamhället. Metoden är att i en livsverksbiografi lyfta fram en av tidens aktörer, nämligen professorskan Agda Montelius. Hon kan ses som en representant dels förThe purpose of this thesis is to shed light on the role of female initiative in the accelerating social developments of the late nineteenth century that were eventually to result in Sweden’s modern, democratic welfare state. The method is a biographical study that highlights one of the leading figures of the day, Agda Montelius. She may be seen as representative not only of those middle and upper
European prospective investigation into cancer and nutrition (EPIC): study populations and data collection
The European Prospective Investigation into Cancer and. Nutrition (EPIC) is an ongoing multi-centre prospective cohort study designed to investigate the relationship between nutrition and cancer, with the potential for studying other diseases as well. The study currently includes 519 978 participants (366 521 women and 153457 men, mostly aged 35-70 years) in 23 centres located in 10 European count
Hydrological effects of water harvesting techniques
Popular Abstract in Swedish Avhandlingen behandlar olika tekniker för regnvatteninsamling i Tunisien och dessas effekt på lokala vattenbalanser och erosion. Tabias, terrassering och småskaliga dammar undersöks. Relevanta hydrologiska processer observeras och modelleras med olika typer av modeller.The thesis investigates hydrological effects of large-scale water harvesting techniques on local water balances as well as sediment erosion. The techniques of tabias, soil contour ridges and small hill reservoirs are investigated. Pertinent processes are observed and simulated using various hydrological models.
