Temperate calcareous grasslands are characterized by high levels of species richness at small spatial scales. Nevertheless, many species from a habitat-specific regional species pool may be absent from local communities and represent the dark diversity' of these sites. Here we investigate dry calcareous grasslands in northern Europe to determine what proportion of the habitat-specific species pool

The estimation of three-dimensional position information from two-dimensional images in computer vision systems can be formulated as a state estimation problem for a nonlinear perspective dynamic system. The multi-output state estimation problem has been treated by several authors using methods for nonlinear observer design. This paper shows that a perspective system can be transformed to two obse

The fibrillatory rate of the surface ECG during atrial fibrillation (AF) has been suggested for quantification of the individual atrial remodeling, to monitor interventions and to predict the response to different therapies. In this dissertation, the relation between fibrillatory rate of the surface ECG and (1) clinical and echocardiographic variables, (2) the outcome of cardioversion, (3) circula

Background: The cell wall component callose is mainly synthesized at certain developmental stages and after wounding or pathogen attack. Callose synthases are membrane-bound enzymes that have been relatively well characterized in vitro using isolated membrane fractions or purified enzyme. However, little is known about their functional properties in situ, under conditions when the cell wall is int

Molecularly imprinted nanoparticles were encapsulated into polymer nanofibers with a simple electrospinning method. The composite nanofibers form non-woven mats that can be used as affinity membrane to greatly simplify solid phase extraction of drug residues in analytical samples. Upward 100% of propranolol-imprinted nanoparticles can be easily encapsulated into poly(ethylene terephthalate) nanofi

The aim of the study was to investigate microstructural changes occurring in unilateral renal ischemia-reperfusion injury in a murine animal model using synchrotron radiation.

Purpose – The rate of turnover of hospital managers has been high in Sweden. Hospitals are regarded to be difficult to manage, which is connected with different discourses and action logics such as politics, medicine, care and management creating complex conditions for hospital management. The purpose of this paper is to analyse hospital managers' management conditions in conjunction with hospital

The PHENIX Collaboration has measured phi meson production in d + Au collisions at root s(NN) = 200 GeV using the dimuon and dielectron decay channels. The phi meson is measured in the forward (backward) d-going (Au-going) direction, 1.2 < y < 2.2 (-2.2 < y < -1.2) in the transverse-momentum (pT) range from 1-7 GeV/c and at midrapidity vertical bar y vertical bar < 0.35 in the p(T) range below 7 G

Popular Abstract in Swedish Bakgrund Trots att venös blodpropp (venös tromboembolism [VTE]) är en viktig orsak till sjuklighet och dödlighet är data ofullständiga gällande dess förekomst och bakomliggande riskfaktorer hos oselekterade patienter. I begreppet VTE inkluderas blodproppar i benets djupa ådror (djup ventrombos [DVT]) och i lungorna (lungemboli [LE]). Insjuknandefrekvens i VTE varierar mDespite the fact that venous thromboembolism (VTE) is an important cause of morbidity and mortality there is still insufficient information on VTE risk factors and patient characteristics in the general population. Previously published incidences of VTE (deep venous thrombosis [DVT] and pulmonary embolism [PE]) vary from 71 to 192 per 100,000 individuals per year. Incidences of DVT and PE have bee

This paper presents results from a modern dataset of non-pollen palynomorphs and its application to a ca. 2,000 year peat record from the same area in the western Pyrenees (Basque Country, France). The modern dataset is composed of 35 surface samples (moss polsters) from a mountainous pasture-woodland landscape. Airborne fungal spores (ascospores and conidia), found dominant in the dataset, are li

Popular Abstract in Swedish Antalet fall av tuberkulos (TB) har ökat parallellt med den globala spridningen av hiv. TB orsakar omkring 1.5 miljoner dödsfall årligen, och är den vanligaste dödsorsaken hos hivpositiva. Under det senaste årtiondet har tillgången till livräddande behandling mot hiv (antiretroviral terapi; ART) ökat kraftigt i låginkomsländer – särskilt i Afrika söder om Sahara. I dessHIV and tuberculosis (TB) remain the two most common infectious causes of death worldwide. During the recent decade antiretroviral treatment (ART) has become available for millions of people living with HIV (PLHIV) globally; yet more than half of PLHIV have not yet initiated ART. In order to achieve universal access, further decentralization of care is needed. This is a major challenge to health s

A low-power high linearity CMOS G(m)-C channel select filter for WLAN/WiMAX receivers in 90-nm CMOS technology is presented. To reduce power consumption a biquad cell with simple architecture is used. A simple but efficient technique is also proposed to improve the linearity of the filter without increasing its power consumption. Coarse and fine tuning techniques are used to tune the cutoff freque

Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy in the upper extremity. Diabetes mellitus increases the risk of developing CTS from an estimated prevalence of 2-4% in the general population to 15-30% in diabetics. Results after carpal tunnel release in diabetic patients with CTS have been sparsely investigated and the basis for its increased prevalence in diabetes is yet unkn
