New observations on the luminescence Of In2S3 and europium-doped In2S3 nanoparticles show a green (5 10 nm) emission from In2S3 and In1.8Eu0.2S3 nanoparticles while a blue (425 nm) emission is observed from ln(1.6)Eu(0.4)S(3) nanoparticles. Both the blue and green emissions have large Stokes shifts of 62 and 110 nm, respectively. Excitation with longer-wavelength photons causes the blue emission t
Two flavones, 4',5,7-trihydroxy-6-methoxy flavone (dinatin) and 4',5-dihydroxy-6, 7-dimethoxy flavone (skrofulein), were extracted from Artemisia herba alba L. Dinatin and skrofulein inhibited the binding of [methyl-3H]diazepam to rat brain membranes in vitro with IC50 of 1.3 and 23 mumol.L-1, respectively. The GABA-ratios (the ratio of IC50 values in the absence/presence of GABA in the binding as
Background and aims: Caregivers of Parkinson's disease patients are vulnerable to detrimental factors related to caregiving because of the progressive course of the disease. Studies of care-givers of these patients are scarce. The aim of this study was to examine the caregiver burden in Parkinson's disease by analyzing caregiver and patient-related factors. Methods: Every 3(rd) patient with Parkin
The first acedemic volume on the history, ideology and social history of Swedish freemasonry. Contains a membership list with 4300 members in Swedish lodges of the 18th century.
In laryngectomized patients a tracheo-esophageal artificial fistula can be used to achieve air flow from the trachea to the esophagus during speech. A one-way plastic valve is often used for the fistula. A free jejunal graft between the trachea and the esophagus can also be used. To avoid aspiration the transplant is attached to the submental area giving the graft a siphon-like shape. We performed
A biochemical oxygen demand (BOD) sensor, based on an immobilised mixed culture of microorganisms in combination with a dissolved oxygen electrode, has been developed for the purpose of on-line monitoring of the biological treatment process for waste and wastewater. The sensor was designed for easy replacement of the biomembrane, thereby making it suitable for short-term use. The drawbacks of acti
Wound healing that precedes scar formation may be unbalanced under pathological conditions leading to structural changes of the tissue. At the moment, the mechanisms behind this unbalance are unclear. When these changes occur in internal organs such as the lung, they may result in organ dysfunction with fatal consequences for the patient. This phenomenon is defined as airway remodeling, and occurs
Background. Around 25 million Caucasian women are carriers of the FV Leiden mutation that causes activated protein C (APC) resistance. This is a heritable condition with a lifelong increased risk of venous thromboembolism. We performed this study to investigate women's reactions to their awareness of being APC-resistant and the consequences of this awareness. Methods. All APC-resistant women (n =

A scheduling architecture for real-time control tasks is proposed. The scheduler uses feedback from execution-time measurements and feedforward from workload changes to adjust the sampling periods of the control tasks so that the combined performance of the controllers is optimized. The performance of each controller is described by a cost function. Based on the solution to the optimal resource al
