A shift towards wetter and windier conditions in southern Sweden around the prominent solar minimum 2750 cal a BP

A variety of palaeoclimatic records show a shift towards cooler, wetter and windier conditions in Europe around 2800 cal a BP. The shift broadly coincides with an increase of the atmospheric C-14 concentration, suggesting a connection between solar activity variations and climate change. Here we investigate a peat record from Undarsmosse in southern Sweden. In a previous study, based on a low-reso

How mankind has shaped European nature

A monographic book volume on the history of the rural landscape of Europe is presented (Emanuelsson, The rural landscape of Europe. How man has shaped European nature, 383, 2009). The focus is on various land-use phases, their history from the Neolithic period to modern time and the survival of traditional farming today in Europe. This is described and illustrated by examples from marginal farming

Clause combining in Semitic : The circumstantial clause and beyond

The volume presents the results of an international project carried out in cooperation between the Uppsala University, the Hebrew University in Jerusalem, Lund University and the University of Gothenburg. The questions put forward in the project were: How is hypotaxis marked in Semitic, other than by conjunctions? How does this affect the organization of texts? More specifically, what constitutes

Leder ungdomars religiösa engagemang till ökad delaktighet och hälsa?

One of the major problems in contemporary Swedish society is an increasing proportion of psychologically ailing young people. It is often argued that one of the reasons for this situation is declining possibilities for young people to actively participate and engage in Swedish society. One important area of participation and involvement for young people could be religious organizations. Thus, the

Mortality of bats at wind turbines links to nocturnal insect migration?

This note is based on a literature search and a recent review of bat mortality data from wind farms in Europe (published elsewhere). We suggest that mortality of bats at wind turbines may be linked to high-altitude feeding on migrating insects that accumulate at the turbine towers. Modern wind turbines seem to reach high enough into the airspace to interfere with the migratory movements of insects

Integration of HIV and cervical cancer screening perceptions and preferences of communities in Uganda

Background: Despite the fact that HIV-positive women carry an increased risk of developing cervical cancer (CC) in comparison with HIV-negative women, HIV and CC screening programs in many developing countries have remained unintegrated. The objective of this study is to explore perceptions and preferences of community members in Uganda, including women, men, and village health teams, regarding th

Diagnostic performance of routine ultrasound screening for fetal abnormalities in an unselected Swedish population in 2000-2005

Objectives To determine the detection rate of fetal malformations and chromosomal abnormalities and the rate of false-positive ultrasound diagnoses at routine ultrasound examinations carried out by specially trained midwives in an unselected pregnant population front 2000 to 2005, and to describe the consequences of true-positive and false-positive ultrasound diagnoses of fetal malformations. Meth

Properties of self-assembled Bi nanolines on InAs(100) studied by core-level and valence-band photoemission, and first-principles calculations

We have studied self-assembled bismuth (Bi) nanolines on the Bi-terminated InAs(100) surface by core-level and valence-band photoelectron spectroscopy, and ab initio first-principles calculations. A structural model for this intriguing surface is suggested based on the comparison of the measured and calculated core-level shifts. Also, the atomic origins for the core-level shifts are proposed based

What are the effects of agricultural management on soil organic carbon (SOC) stocks?

Background: Changes in soil organic carbon (SOC) stocks significantly influence the atmospheric C concentration. Agricultural management practices that increase SOC stocks thus may have profound effects on climate mitigation. Additional benefits include higher soil fertility since increased SOC stocks improve the physical and biological properties of the soil. Intensification of agriculture and la

On the Generalization of the GMS Evolutionary Model

We study a generalization of the evolution model proposed by Guiol, Machado and Schinazi [4]. In our model, at each moment of time a random number of species is either born or removed from the system; the species to be removed are those with the lower fitnesses, fitnesses being some numbers in [0, 1]. We show that under appropriate conditions, a set of species approaches (in some sense) a sample f

Sex differences in the association between body mass index and total hip or knee joint replacement resulting from osteoarthritis

Objective: To examine the association between body mass index (BMI) and osteoarthritis (OA) leading to total hip (THR) or knee (TKR) joint replacement. Methods: Case-control study design. All patients still living in Iceland who had had a THR or TKR resulting from OA before the end of 2002 were invited to participate. First-degree relatives of participating patients served as controls. A total of

The aim of our work was to calculate basic mathematical characteristics of payment functional, such as mathematical expectation, variation and expected risk in discrete and continuous market models. In our paper we present a model of financial market in which the entire time interval in the continuous model is divided into steps with exponential distribution, and in the discrete model into steps o

Effects of linear amphiphilicity on membrane interactions of C-terminal thrombin peptides

Effects of linear amphiphilicity on membrane interactions of antimicrobial peptides were investigated by ellipsometry, dual polarization interferometry, fluorescence spectroscopy, light scattering, and circular dichroism. In doing so, the thrombin-derived GKY25 (GKYGFYTHVFRLKKWIQKVIDQFGE) was compared to WFF25 (WFFFYYLIIGGGVVTHQQRKKKKDE) of identical composition, but with amino acids sorted accord

Statistical Energy Determination in Neutron Detector Systems for Neutron Scattering Science

This contribution evaluates the feasibility and potential of a statistical determination of the neutron energy for thermal and cold neutrons in the new generation of neutron detectors. For the European Spallation Source (ESS), sited in Lund, Sweden, which is planned to be operational in 2019, and the world's leading source for the study of materials with neutrons by 2025, novel neutron detectors r

AAK-type theorems for Hankel operators on weighted spaces

We consider weighted sequence spaces on N with increasing weights. Given a fixed integer k and a Hankel operator Gamma on such a space, we show that the kth singular vector generates an analytic function with precisely k zeroes in the unit disc, in analogy with the classical AAK-theory of Hardy spaces. We also provide information on the structure of the singular spectrum for Hankel operators, appl

Intimate partner violence against women in rural Vietnam - different socio-demographic factors are associated with different forms of violence: Need for new intervention guidelines?

Background: This population-based study investigated the different forms, magnitude and risk factors of men's violence against women in intimate relationships in a rural part of northern Vietnam and whether a difference in risk factors were at hand for the different forms of violence. Vietnam has undergone a rapid transition in the last 20 years, moving towards a more equal situation for men and w
