Measurements of the adiabatic laminar burning velocities of n-heptane, iso-octane, ethanol and their binary and tertiary mixtures are reported. Non-stretched flames were stabilized on a perforated plate burner at 1 atm. The Heat Flux method was used to determine burning velocities under conditions when the net heat loss from the flame to the burner is zero. Initial temperatures of the gas mixtures
BACKGROUND: Female sex pheromones attracting mating partners over long distances are a major determinant of reproductive isolation and speciation in Lepidoptera. Males can also produce sex pheromones but their study, particularly in butterflies, has received little attention. A detailed comparison of sex pheromones in male butterflies with those of female moths would reveal patterns of conservatio
Prenatal diagnosis in the third pregnancy of a mother who already had one healthy son and one son with Fanconi anaemia (FA), revealed that her fetus was also affected with FA. At 22 weeks a maternal complaint about excessive fetal kicking starting at 15 weeks, focused our attention on the behaviour of the fetus, which was observed by means of real-time ultrasound for 30 min. The differentiation of
A high excess mortality is well described after hip fracture. Deaths are in part related to comorbidity and in part due directly or indirectly to the hip fracture event itself (causally related deaths). The aim of this study was to examine the quantum and pattern of mortality following hip fracture. We studied 160,000 hip fractures in men and women aged 50 years or more, in 28.8 million person-yea
We use a nested-grid version of the GEOS-Chem chemistry transport model, constrained by isoprene emissions from the Model of Emissions of Gases and Aerosols from Nature (MEGAN), and the Lund-Potsdam-Jena General Ecosystem Simulator (LPJ-GUESS) bottom-up inventories, to evaluate the impact that surface isoprene emissions have on formaldehyde (HCHO) air-mass factors (AMFs) and vertical column densit
Tasquinimod is an anti-tumor drug that is currently in clinical development for the treatment of solid cancers. After oral administration, tasquinimod and a number of its metabolites are excreted in the urine. The quantitative determination of tasquinimod in urine is challenging because of the required sensitivity (down to 0.1nM or 40pg/mL), the highly variable nature of this biological matrix and
A detailed stratigraphical, palaeoecological and geomorphological reconstruction of a fjord head on South Georgia (Husvik, Stromness Bay) is presented. Six sites were chosen to reconstruct the lithostratigraphy of the area by means of coring. A maximum depth of 11m was attained and the sediments encountered vary from coarse gravel over sands to fine silts with, in some cases, intercalated peat lay
The team behavior literature is ambiguous about the relations between members’ interpersonal processes—task debate and task conflict—and team performance. From a social influence perspective, we show why members’ interpersonal processes determine team performance over time in small groups. Together, over time, dissenting in-group minorities who share information (via debate) with majorities, who s
The structure and motion problem of multiple one- dimensional projections of a two-dimensional environment is studied. One-dimensional cameras have proven useful in several different applications, most prominently for autonomous guided vehicles, but also in ordinary vision for analysing planar motion and the projection of lines. Previous results on one-dimensional vision are limited to classifying
Popular Abstract in Swedish Hos människan lever en rad mikroorganismer som tillsammans utgör normalfloran. Normalfloran återfinns på alla kroppsytor, det vill säga huden och slemhinnorna i munnen, svalget, magsäcken, tunn- och tjocktarmen, vagina och urinrörsmynningen. Samspelet mellan människokroppen och mikroorganismerna utsätts dagligen för påfrestningar. En sådan naturlig påfrestning är de sjuThis thesis is concerned with a family of bacterial surface proteins expressed by different strains of the anaerobic Gram-positive, commensal and human pathogen Peptostreptococcus magnus. These proteins have been studied with respect to their role in virulence, function, structure, and evolution. Strains isolated from patients with vaginosis have previously been shown to be associated with express
A method for assessing disturbances in SISO loops has been developed. The method indicates if the SISO loop under consideration will benefit from an addition of feedforward control from a measured disturbance. An implementation in Java of the methodology is presented in the paper.
Steady-state and time-resolved fluorescence studies were performed on aqueous solutions of poly(acrylic acid) hydrophobically modified with two very different levels of naphthalene (Np). It is demonstrated that unique information on association phenomena involving hydrophobe-modifed polymers can be obtained from an extended fluorescence study by using data for a less-modified polymer as a referenc
Abstract in UndeterminedRecording eye movement data with high quality is often a prerequisite for producing valid and replicable results and for drawing well-founded conclusions about the oculomotor system. Today, many aspects of data quality are often informally discussed among researchers but are very seldom measured, quantified, and reported. Here we systematically investigated how the calibrat
