Extensive vegetated roofs are becoming popular as a way to improve the environmental quality of cities. As more vegetated roofs are installed, there is a need for knowledge pertaining to maintenance and impact vegetated roofs have on stormwater quality Our study investigated nutrient runoff, substrate nutrient storage and plant uptake following fertilisation of vegetation mats, shoot-established v

The ability of in vitro-expanded neural precursor cells or cell lines to differentiate following transplantation has significant implications for current research on central nervous system repair. Recently, interest has been focussed on grafts of such neural precursors implanted also into the eye or retina. Here, we demonstrate with a non-traumatizing subretinal transplantation method, that grafts

An hypothesis is presented that provitamin D (dehydrocholesterol and/or ergosterol) can act as a UV-B receptor in plants and algae. We also propose that the proportions between provitamins D, previtamins D, and vitamins D (D2 and D3), after calibration, can be used to evaluate UV-B exposure of phytoplankton and terrestrial vegetation. This is the final, accepted and revised manuscript of this art

During recent decades, concern about the loss of biodiversity on agricultural land has increased, and semi-natural grasslands have been highlighted as critical habitats. Temperate European agricultural landscapes require distinct and appropriate management to prevent further impoverishment of the flora and fauna. This is especially urgent for pollinating insects that provide important ecosystem se

Objective - To study factors of importance for participation in parental education within routine child health care. Design - All parents of children born during 1 year were invited by the district nurse to participate in parental education; their participation during the infant year was registered. Setting - Catchment area of two health centres in Vaxjo, Sweden. Subjects - 221 infants and their p

Both increased and decreased dyskinesias have been reported from open label clinical trials of transplantation of human embryonic dopamine rich tissue in Parkinson's disease patients. In the first double-blind clinical transplantation trial, 15% of the grafted patients developed severe postoperative dyskinesias in the “off” phase. Since then, postoperative off-medication dyskinesias have been repo

OBJECTIVE: To study the relationships between plasma insulin-like growth factor-1 (IGF-1) concentrations and birth weight, current weight and other constitutional factors among healthy, nulliparous women aged 19-25 years.DESIGN AND METHODS: Forty healthy female university students aged 19-25 years volunteered for this study. They had never been pregnant and were not using oral contraceptives (OCs)

The ionization dynamics of Ar and Xe clusters irradiated with intense vacuum ultraviolet light from a free-electron laser is investigated using photoelectron spectroscopy. Clusters comprising between 70 and 900 atoms were irradiated with femtosecond pulses at 95 nm wavelength (similar to 13 eV photon energy) and a peak intensity of similar to 4x10(12) W/cm(2). A broad thermal distribution of emitt

Objectives: To examine if a low level of psychosocial resources in early pregnancy is associated with the occurrence of prolonged tabour. Study design: A cross sectional study of 644 women expecting their first child. Participants were asked to complete a questionnaire at their first antenatal visit, measuring psychosocial resources defined as social network and support, work-related psychosocial

The preferences of some woodland understorey species for ammonium and nitrate were investigated by measuring the potential nitrification (conversion of ammonium to nitrate) in the rhizosphere compared with the bulk soil. Less acid-tolerant species, which usually prefer nitrate or a mixture of ammonium and nitrate in hydroponic culture, should have a higher potential nitrification in the rhizospher

Purpose: To evaluate long-term patency and clinical efficacy of subintimal angioplasty (SAP) of occluded infrainguinal arteries 3 years post procedure. Methods: One hundred eighty-one patients (92 men; median age 79 years) underwent attempted SAP in 193 limbs with occluded infrainguinal arteries during the period 1999 to 2001. Nearly half (83, 46%) of the patients had diabetes. Most (172, 95%) had

Abstract The aim of this article is to introduce a conceptual framework for a corporate brand building process based on core values. The nature, role, and function of core values are considered a central part of the value foundation of a corporate brand. In line with this reasoning, a distinction is also made between three groups of values: organisational values, core values, and added values. Th

Here we unravel the structural features of human IgM and IgA that govern their interaction with the human Fc alpha/mu receptor (hFc alpha/mu R). Ligand polymerization status was crucial for the interaction, because hFc alpha/mu R binding did not occur with monomeric Ab of either class. hFc alpha/mu R bound IgM with an affinity in the nanomolar range, whereas the affinity for dimeric IgA (dIgA) was

The percentages of Type I muscle fibres were measured systematically in ATPase-stained, transverse cryostat sections of whole tibialis cranialis muscles from 8 young, adult beagles. The distance of the section from the origin of the muscle does not significantly affect the mean percentage. There are no identifiable differences in mean percentages between right and left muscles. Differences in mean
