I examined the costs of producing and maintaining floral structures in Nigella degenii (Ranunculaceae). To test for such costs, I subjected plants of two populations to flower or perianth removal and then evaluated allocation to subsequently produced flowers, fruits, and seeds. Based on data from a flower removal experiment, the amount of resources allocated to flowers during the staminate and pis
The regioselectivity in the Rh catalysed 1,4-hydrosilylation of isoprene was investigated. Variation of solvents and temperature did not significantly affect the isomer distribution between tail-product (I) and head-product (II). The choice of ligands had the greater influence, where Rh-I-based catalysts with the strong electron withdrawing ligand CO favoured production of isomer II, while Rh-I ca
Hotspots and coldspots of concentration and biodegradation of polycyclic aromatic hydrocarbons (PAHs) marginally overlapped at the 0.5-100 m scale in a creosote contaminated soil in southern Sweden, suggesting that concentration and biodegradation had little spatial co-variation. Biodegradation was substantial and its spatial variability considerable and highly irregular, but it had no spatial aut
InGaAs nanowires grown by Metalorganic Vapor Phase Epitaxy (MOVPE) are promising candidates in future device technologies. The control of the chemical composition of InGaAs nanowires is not trivial due to the In atom diffusion from the substrate, which causes significant variations in the chemical composition along the nanowire. In this work, we report on the growth of InGaAs nanowires on (111)B I
Aim: To compare adaptive functioning in children with mild intellectual disability (MID) with that of children with attention-deficit/hyperactivity disorder (ADHD). Methods: Thirty-three children with MID were contrasted with 27 children with ADHD with regard to adaptive functioning as measured by the Adaptive Behaviour Assessment System (ABAS-II). The group with MID was population-based, and the
Electromagnetic induction measurements (EM) were taken in a saline gypsiferous soil of the Saharan-climate Fatnassa oasis (Tunisia) to predict the electrical conductivity of saturated soil extract (ECe) and shallow groundwater properties (depth, Dgw, and electrical conductivity, ECgw) using various models. The soil profile was sampled at 0.2 m depth intervals to 1.2 m for physical and chemical ana
Problem: Suspected, but objectively absent, rhinosinusitis constitutes a major cause of visits to the doctor, high health care costs, and the over-prescription of antibiotics, contributing to the serious problem of resistant bacteria. This situation is largely due to a lack of reliable and widely applicable diagnostic methods. Method: A novel method for the diagnosis of rhinosinusitis based on non
Rapidly permineralized fossils can provide exceptional insights into the evolution of life over geological time. Here, we present an exquisitely preserved, calcified stem of a royal fern (Osmundaceae) from Early Jurassic lahar deposits of Sweden in which authigenic mineral precipitation from hydrothermal brines occurred so rapidly that it preserved cytoplasm, cytosol granules, nuclei, and even chr
In order to explore verbal-nonverbal integration, we investigated the influence of cognitive and linguistic ability on gaze behavior during spoken language conversation between children with mild-to-moderate hearing impairment (HI) and normal-hearing (NH) peers. Ten HI-NH and 10 NH-NH dyads performed a referential communication task requiring description of faces. During task performance, eye move
PURPOSE. Integration between subretinal grafts and the host retina is limited in part by the presence of a barrier at the graft-host interface. This study was conducted to identify factors that may contribute to this barrier, by examining the distribution of glial structures and associated molecules in different setups of overlapping retinal pieces. METHODS. Neuroretinal tissue derived from mice t
A method is described in which light gradients and spectral regime can be measured within plant tissue using fiber optics. A fiber optic probe was made by modifying a single optical fiber (200 μm diameter) so that it had a light harvesting end that was a truncated tip 20–70 μm in diameter. The probe was a directional sensor with a half-band acceptance angle of 17–20°. Light measurements were made
Popular Abstract in Swedish Gasturbiner har länge varit en ekonimsk och driftsäkert sätt att producera energi. Främst har dom använts för framdrivning av flygplan och production av elektricitet och värme. Dom ständigt ökade kraven på miljöfarliga emissioner har tvingat fram nya metoder för att producera kraft. Nästa generations kraftverk måste ha hög termisk verkningsgrad samt mycket låga emissionGas turbines have served as economically profitable and reliable generators of power for the past few decades, and have mainly been used in simple and combined cycles. The increased restrictions on hazardous emissions and the increased demand for profitability have created new prospects for innovative power cycles. The requirements for these new power cycles are substantially better emissions, hig
In the framework of the semi-hard (k(T)-factorization) approach, we analyze the various charm production processes in the kinematic region covered by the HERA experiments.
OBJECTIVE--The aim was to study the association between personal factors and physical and psychosocial work environment factors and disorders of the neck or upper limbs among women in the fish processing industry. METHODS--A cross sectional study was performed on 206 women in the fish processing industry and 208 control women. Several physical and psychosocial work environment factors were evaluat
Background: alpha1-antitrypsin (AAT) is one of the major serine proteinase inhibitors controlling proteinases in many biological pathways. There is increasing evidence that AAT is able to exert other than antiproteolytic effects. To further examine this question we compared how various doses of the native (inhibitory) and the polymerised (non- inhibitory) molecular form of AAT affect pro-inflammat
The parental questionnaire FTF (Five to Fifteen) was given to parents of 76 children (mean age 11 years) diagnosed with ADHD. About half of the children had at least once been referred to a speech- and language pathologist. Most of them had not received any intervention or follow-up. A factor analysis identified six problem areas, which explain close to 75% of the total variation: Cognitive Skills
