Climatic and environmental changes during the Younger Dryas stadial (GS-1) and preceding and following transitions are inferred from stable carbon and oxygen isotope records obtained from the sediments of ancient Lake Torreberga, southern Sweden. Event GS-1 is represented in the sediment sequence by 3.5 m of clay containing lacustrine carbonates of various origins. Comparison of isotopic records o

A simple model is presented which interpolates between the DGLAP and BFKL regimes in deep inelastic cp scattering. This model is based on the CCFM and LDC models, and it is simple enough to provide an intuitive picture of the transition region between the two domains. Results are presented for both fixed and running coupling; for fixed coupling the transition between the domains occurs at a consta

Källa on Öland is used as a point of departure in a discussion of the so-called defensive churches or multi-functional churches at the Baltic Sea. The categorization of medieval society into four separate spheres, the church, the castle, the town and the countryside, is criticised as having created a heterogenous group of deviant churches. The deviant churches have been interpreted in three compet

The past decade has witnessed a marked increase in distributed system complexity. This was driven by a maturing technology that steadily decreased the number of faults. Unfortunately these fewer faults have become exponentially more costly. It becomes mandatory to detect faults prior to taking effect on the network. Such an early detection requires a new test detection and fault containment strate

Objectives: To examine the diameter and distensibility of the abdominal aorta in patients with severe α1-antitrypsin deficiency, and to compare the results with those of normal subjects. Material and methods: Abdominal aortic diameter and stiffness (β) was measured using echo-tracking sonography in 19 men (mean age 50, range 25–79) and 17 women (mean age 46, range 26–62) with severe α2-antitryps

Minimum variance control of difference equations systems with time-varying stochastic parameters are studied. The optimal control law is derived under the assumption that all previous, but not the current parameter values are known. This is used to give performance limits for dual control. In particular, it is shown that too much parameter uncertainty may cause the system to be unstable in the sen

The diastereoselectivity of the carbonyl reduction of bicyclo[2.2.2]octane-2,6-dione, catalysed by the purified yeast cytosolic short-chain dehydrogenase Ymr226cp, was shown to be substrate concentration dependent. The changing selectivity was attributed to two distinct binding configurations of the substrate in the active site, each yielding a distinct hydroxy ketone diastereomer. By applying ind

Ett historiskt fall, fem personer som under stora nordiska kriget med hjälp av en båt försökte fly till Danmark undan utskrivningar och elände men fastnade på Lägerholmen, en ö längst ut i skärgården utanför nordöstra Skåne.

Objectives To ascertain whether the risk for congenital malformations is increased in pregnancies with deviating fetal growth, i.e. in those in which the estimated date of delivery (EDD) was postponed more than 1 week at the second- trimester ultrasound fetometry scan, or those suspected of intrauterine growth restriction at routine ultrasound fetometry in the third trimester. Methods The study pe

The early Middle Ages saw the formation of the three Nordic kingdoms of Sweden, Norway and Denmark, and at that time the area studied here constituted a border region between them. During the same period the Church was very active in the area: a bishopric was established and a large number of churches were built. This makes the area a particularly interesting one to study from the point of view of

Repeated exposures to both microbial and innocuous Ags in vivo have been reported to both eliminate and tolerize T cells after their initial activation and expansion. The remaining tolerant T cells have been shown to suppress the response of naive T cells in vitro. This feature is reminiscent of natural CD4+CD25+ regulatory T cells. However, it is not known whether the regulatory function of in vi

The carabid beetle Harpalus rufipes has been examined with respect to food preference and food quality. Three different experiments were performed to clarify the role of weedy seeds and insects as food for H. rufipes: 1) adult's food preference, 2) fecundity dependent on diet, and 3) larval development dependent on diet. No direct relation between food preference and food value was found. The seed

Context: Protein profiling of diabetic tissues could provide useful biomarkers for early diagnosis, therapeutic targets, and disease response markers. Cultured fibroblasts are a useful in vitro model for proteome analysis and study of the molecular mechanisms involved in diabetes. Objective: The objective of the study was to isolate and characterize the proteins of cultured fibroblasts, obtained b

Rat models are useful for studies of the pathogenesis of rheumatoid arthritis (RA) since rats are extraordinarily sensitive to induction of arthritis with adjuvants. Injection of not only the classical complete Freund's adjuvant but also mineral oil without mycobacteria and pure adjuvants such as pristane and squalene, induce severe arthritis in many rat strains. Models like pristane-induced arthr
