Mechanically strong and flexible membranes with very high local concentrations of immobilized proton-conducting phosphonic acid have been achieved by grafting poly(vinylphosphonic acid) side chains onto polysulfones. The graft copolymers were prepared by anionic polymerization of diethyl vinylphosphonate initiated from lithiated polysulfones, followed by quantitative cleavage of the ester function

Female mate-choice based on genetic compatibility is an area of growing interest. The major histocompatibility complex (MHC) genes are likely candidates for such mate-choice since these highly polymorphic genes may both increase offspring viability and also provide direct cues for mate-choice. In great reed warblers, females actively choose a breeding partner out of a handful of males that they vi

In a population of 956 women, attending for contraceptive advice, 131 (13.7%) were found to have BV acording to Amsel's criteria. Clue cells were detected in 200 (20.9%) women, a positive amine ('sniff') test in 191 (20.0%), a vaginal pH > or = 4.7 in 243 (25.4%) and a "characteristic" vaginal discharge in 104 (10.9%) women. Sensitivity, specificity, positive and negative predictive values in rela

A balance sheet of the Cuban Revolution in terms of growth performance, equity, and the satisfaction of basic needs after 50 years is a mixed bag. Growth performance has been disappointing during most of the past 25 years, although there are today some encouraging new trends. Income distribution that was quite equal in 1985 has seen some deterioration since 1990. Agriculture has been one of the fa

Chlorophyll a (Chl a) serves a dual role in oxygenic photosynthesis: in light harvesting as well as in converting energy of absorbed photons to chemical energy. No other Chl is as omnipresent in oxygenic photosynthesis as is Chl a, and this is particularly true if we include Chl a2, (=[8-vinyl]-Chl a), which occurs in Prochlorococcus, as a type of Chl a. One exception to this near universal patter

Increased activity in the sympathetic nervous system is part of the physiological stress response and is expressed in the heart rate variability (HRV). The objective of this study was to examine associations of HRV and intima media thickness (IMT). In 2002, satisfactory measurements of HRV of 78 voluntary participants were made, both during a stress test and during sleep. IMT in 2002 and the progr

Artikeln ”Facklig styrka eller reformistisk strategi?” publicerades i Zenit nr 4 (nr 86) 1984 som en kommentar till Anders Perssons recension i Zenit nr 2 (nr 84) 1984 av Anders Kjellbergs doktorsavhandling Facklig organisering i tolv länder (Lund: Arkiv förlag 1983). Redaktionen klippte dock av utrymmesskäl bort ett stycke som under rubriken ”Facklig styrka – än en gång!” publicerades i Zenit nr

By putting emphasis on applications in two basic statistics courses for chemistry students and chemical engineering students we have enhanced student motivation and increased student activity. In addition to a traditional in-class exam, the students complete a take-home project where statistical problems relevant to chemists are discussed. We give several examples of the course and project materia

Objective To examine prospectively whether inflammatory biomarkers and endothelin (ET)-1 are increased in patients with renal artery stenosis (RAS), and to investigate how treatment with percutaneous transluminal renal angioplasty (PTRA) affects these variables during the first month after intervention. Methods One hundred patients with suspected RAS undergoing renal angiography were included. PTR

Utsikter - föreläsnngar från Helgonabacken ("Views - Lectures from Helgonabacken" consists of public lectures by teachers at the Department for Comparative Literature, Lund university. Most of the lectures deal with contemporary Swedish literature, but there are also texts on Italian and Danish poetry and American cinema.

Connections between interpolation spaces, Pick functions, and matrix monotone functions are investigated. Characterizations, inclusion results, open problems, and conjectures on these function classes and their interrelations are presented.

A general and somewhat popularized introduction to the Consuetudines Lundenses, i.e. the customary of the cathedral chapter of early twelfth-century Lund, its employment, and content.

Context: Testis development is a tightly regulated process that requires an efficient and coordinated spatiotemporal action of many factors, and it has been shown that several genes involved in gonadal development exert a dosage effect. Chromosomal imbalances have been reported in several patients presenting with gonadal dysgenesis as part of severe dysmorphic phenotypes. Results: We screened for

Operatively induced, standardized tibia fractures in 42 10-week-old male rats were fixed with intramedullary nails. 21 of the rats were fed liquid containing 15% ethanol. 5 weeks after inducing the fracture, the rats were killed and the total body bone mineral density (BMD) was analyzed with the DEXA technique, and the mechanical properties of the fractured and the unfractured tibiae as well as th

A high order accurate and fast algorithm is constructed for 2D stress problems on multiply connected finite domains. The algorithm is based on a Fredholm integral equation of the second kind with non-singular operators. The unknown quantity is the limit of an analytic function. On polygonal domains there is a trade-off between stability and rate of convergence. A moderate amount of precomputation

Prostate-specific antigen (PSA) is a widely used marker for prostate cancer. In the literature, there are reports of nonprostatic expression of PSA that potentially can affect early diagnosis. However, the results are scattered and inconclusive, which motivated us to conduct a more comprehensive study of the tissue distribution of PSA and the closely related protein human glandular kallikrein 2 (h
