Frogs are often rare or absent from intensively farmed areas. Here we explore the possibility that the landscape and the quality of the terrestrial habitat are unsuitable for these populations. Spawn of Rana arvalis and R. temporaria was introduced into ponds in a south Swedish agricultural landscape in 2003 (eight ponds) and 2004 (ten ponds). Metamorphs emerged from nine (R. a.) and 12 (R. t.) of
Joint property units and joint facilities are an integral part of the Swedish cadastral system. They are a result of the 19th century land reforms, where the units guaranteed a common resource system (roads, mills, drainage systems etc.) for externalities of the individual property. Today, several of these joint property units are unused and constitute land of low value. Joint facilities exist wit
Sediment pigments as an indicator of water column and benthic processes have become widely used during the last decades. However, the effect of different storage and handling conditions on the accuracy of sediment pigment analyses has not been adequately evaluated. This can potentially make comparisons between studies difficult and, at worst, call into question the validity of some studies. Even t
This poster concerns the articulation of uvular consonants with particular reference to quantal aspects of speech production. Data from X-ray motion films are presented. Two speakers of Southern Swedish give examples of [R], and one speaker of West Greenlandic Inuit gives examples of [R] and [q]. Traditionally, uvular consonants are said to be produced by articulating the dorsum against the uvula.
We propose a method for detection of the degree of infection in the paranasal sinuses utilizing a previously published method whereby the viscosity in a sealed container may be measured using an ultrasound Doppler method. As ultrasound propagates in a liquid medium, due to attenuation, the resulting pressure gradient will cause the liquid to move in the propagation direction - the wellknown effect
Flame flashback from the combustion chamber to the premixing section is a major operability issue when using high H-2 content fuels in lean premixed combustors. Depending on the flow-field in the combustor, flashback can be triggered by different mechanisms. In this work, three flashback mechanisms of H-2/CH4 mixtures were visualized in an atmospheric variable swirl burner using high speed OH chem
The development of treatments based on cognitive models of worry has led to improved outcomes for adults with Generalized Anxiety Disorder (GAD), and holds out the promise that similar improvements may be achieved for GAD further down the age range. The aim of the current study was to evaluate the effect of a GAD specific,cognitive treatment in a sample of children and adolescents with GAD. Sixtee
A novel approach to background/foreground segmentation using an online EM algorithm is presented. The method models each layer as a Gaussian mixture, with local, per pixel, parameters for the background layer and global parameters for the foreground layer, utilising information from the entire scene when estimating the foreground. Additionally, the online EM algorithm uses a progressive learning r
The 16O(gamma,pn) reaction has been measured with a resolution high enough to resolve individual low-lying states in the residual 14N nucleus. The relative population of the states provides detailed information about the quantum numbers of the proton-neutron pairs on which photons are absorbed. Partial cross-sections, available to the acceptance of the detector system, have been extracted for the
Background Positivism is sometimes rejected for the wrong reasons. Influential textbooks on nursing research and in other disciplines tend to reinforce the misconceptions underlying these rejections. This is problematic, since it provides students of these disciplines with a poor basis for making epistemological and methodological decisions. It is particularly common for positivist views on realit
Osteoporosis and subsequent fractures is a rapidly growing major health problem in many parts of the world. Even if prevalence and incidence are high in Europe, rate of increase is even higher in Asia. The majority of fractures occur in women underlining the importance of ovarian deficiency. Genetic factors and lifestyle greatly influence the incidence and prevalence both in men and women and the
The reliability of the correlation dimension estimation in short hydrological time series is investigated using an inverse approach. According to this approach, first predictions are made using the phase-space reconstruction technique and the artificial neural networks. The correlation dimension is estimated next independently and is compared with the prediction results. A short hydrological serie
