In aqueous surfactant and lipid systems, different liquid crystalline phases are formed at different temperatures and water contents. The "natural" phase sequence implies that phases with higher curvature are formed at higher water contents. On the other hand, there are exceptions to this rule, such as the monoolein/water system. In this system an anomalous transition from lamellar to reverse cubi

Popular Abstract in Swedish Även om civil flygindustri har genomgått stora teknologiska och kommersiella förändringar under de senaste årtiondena så har grundläggande civil flygutbildning inte förändrats på motsvarande sätt. Förändringarna inom civilflyget har sällan resulterat i forskningsprogram med inriktning mot grundläggande flygutbildning och denna utbildningsfas har länge varit föremål för Although the civil aviation industry has gone through great technological and commercial change in the last decades, basic civil aviation training has not kept pace accordingly. The changes in civil aviation have rarely resulted in research programs in the field of basic training, which has long received minimal attention from the industry. In the research presented in this thesis, methods for und

High-spin states of the isospin T-z = -1/2 nucleus Ni-55 have been identified for the first time by means of the reaction Si-28(Ar-36,2 alpha n) at 143 MeV beam energy. The GAMMASPHERE array together with ancillary detectors was used to detect gamma rays in coincidence with evaporated light particles. The level scheme of Ni-55 comprising four transitions is compared to its mirror partner Co-55 and

In many species, population sex ratios have far-reaching consequences for a wide variety of population-level and behavioural processes and can directly influence sexual selection through differential effects on male and female mating behaviour. Although sex ratios are often treated as more or less stable population characteristics, recent theoretical evidence suggests that sex ratios fluctuate und

Reduction in the amount of ammonia in fuel gas from biomass gasification was studied. Experiments were carried out in a fixed-bed reactor dt 200-1000 degrees C, 21 atm. A kinetic model for ammonia decomposition was developed. The partial pressure of hydrogen in the fuel gas was a key factor to model ammonia decomposition. Activation energies in the empty reactor, on carbon, and in a sand bed were

Context: The use of levothyroxine to reduce thyroid size in pediatric patients with goiter due to chronic autoimmune thyroiditis (AIT) remains controversial. In overtly hypothyroid patients, reductions in thyroid volume have been reported, whereas the effect in subclinically hypothyroid and euthyroid patients is less clear. Objective: The objective of the study was to evaluate the effect of levot

Apoptosis is characterized by a lack of inflammatory reaction in surrounding tissues, suggesting local control of complement activation. During the initial stage of apoptosis, cells expose negatively charged phospholipid phosphatidylserine on their surfaces. The vitamin K-dependent protein S has a high affinity for this type of phospholipid. In human plasma, 60-70% of protein S circulates in compl

Two groups of Mongolian gerbils (Meriones unguiculatus) were continuously exposed to 150 ppm trichloroethylene (TCE) for 77 and 106 d, respectively. The behavior of the animals was tested in a symmetrical maze baited with sunflower seeds during a period of 23 d, beginning at the end of exposure. One additional group was exposed for 150 d and then allowed 40 d free from exposure before the start of

A new 250 MeV energy electron pulse-stretcher mode is designed where the MAX I ring is injected from a new linac system (Nucl. Instr. and Meth. A 490 (2002) 592). For the new slow extraction, we will try to achieve a lower emittance in the extraction plane by using a different extraction method. Injection and slow extraction are simulated.

This doctoral dissertation is based on five appended papers primarily concerned with three main topics, namely: the functional characterization of specific and clinically relevant perturbations found in BRCA1 ? one of the major breast cancer susceptibility genes; the use of microarray technologies for molecular characterization of hereditary breast tumor samples from a genomic perspective; and fin

Exercise-induced rib stress fractures have been reported frequently in elite rowers during the past decade. The etiology of rib stress fractures is unclear, but low bone mineral density (BMD) has been suggested to be a potential risk factor for stress fractures in weight-bearing bones. The present study investigated BMD in seven Danish national team rowers with previous rib stress fracture (RSF) a
