A miniaturized supported liquid membrane device has been developed for sample preparation and connected on-line to a packed capillary liquid chromatograph. The device consists of hydrophobic polypropylene hollow fiber, inserted and fastened in a cylindrical channel in a Kel-F piece. The pores of the fiber are filled with an organic solvent, in this study 6-undecanone, thus forming a liquid membran

This article investigates the performance of five commonly used density functionals, B3LYP, BP86, PBE0, PBE, and BLYP, for studying diatomic molecules consisting of a first row transition metal bonded to H, F, Cl, Br, N, C, O, or S. Results have been compared with experiment wherever possible. Open-shell configurations are found more often in the order PBE0 > B3LYP > PBE similar to BP86 > BLYP. Ho

Two packed-bed bioreactors filled with carriers of foamed glass beads were tested at 14 degrees C (bioreactor RA) or at 23 +/- 1 degrees C (bioreactor RB) for the continuous treatment of a mixture of 2-chlorophenol (2CP), 4-chlorophenol (4CP), 2,4-dichlorophenol (DCP) and 2,4,6-trichlorophenol (TCP). The reactors were inoculated by mixed bacterial consortia acclimatized to the pollutants at each t

ventilation/perfusion scintigraphy (V/P-SCAN) was the procedure of choice for studying patients with suspected pulmonary embolism (PE) until the prospective evaluation of V/P imaging in the study known as PIOPED I revealed high number of non diagnostic findings. This has challenged development of computed tomography (CT) during 1990s. Since beginning of 2000, multidetector CT (MDCT) is widely appl

Müller cells are essential in creating and maintaining intricate neuroretinal architecture. The functions of this important glial cell are not limited to mere support of the retinal neurons, but also include interaction in synaptic transmission and activation in response to retinal insult. In this study, we have examined Müller cell morphology and degree of activation in embryonic full-thickness r

Sivakumar et al. (2000a), by employing the correlation dimension method, provided preliminary evidence of the existence of chaos in the monthly rainfall-runoff process at the Göta basin in Sweden. The present study verifies and supports the earlier results and strengthens such evidence. The study analyses the monthly rainfall, runoff and runoff coefficient series using the nonlinear prediction met

We present an age model for the 651g€¯m deep ice core from Skytrain Ice Rise, situated inland of the Ronne Ice Shelf, Antarctica. The top 2000 years have previously been dated using age markers interpolated through annual layer counting. Below this, we align the Skytrain core to the AICC2012 age model using tie points in the ice and air phase, and we apply the Paleochrono program to obtain the bes

Hand osteoarthritis (OA) is a common form of OA, for which education and exercise are considered the first-line treatment. The aim of the present study was to examine pain and perceived hand function in participants following 3 months of digitally delivered first-line treatment for hand OA. Three-hundred-and-seventy-nine of 846 participants with clinical signs and symptoms of hand OA completed the

Background: Parents of children with complex right ventricular outflow tract (RVOT) anomalies are con-fronted with their child’s need for heart surgery early in life and repeated reoperations later on. Preoperative assessment needs to be performed whenever an indication for reoperation is suspected. The aim was to illuminate the experiences of parents of children diagnosed with RVOT anomalies, in

BACKGROUND: The outcome after weaning from postcardiotomy venoarterial extracorporeal membrane oxygenation (VA-ECMO) is poor. In this study, we investigated the prognostic impact of arterial lactate levels at the time of weaning from postcardiotomy VA.METHODS: This analysis included 338 patients from the multicenter PC-ECMO registry with available data on arterial lactate levels at weaning from VA

ObjectiveAs part of our research on Swedish school principals, we examined the concurrent validity between the Karolinska Exhaustion Disorder Scale (KEDS) and the Lund University Checklist for Incipient Exhaustion (LUCIE) in a cross-sectional study sample (N = 2670). Specifically, we examined: (a) to what extent LUCIE and KEDS identified the same individuals and their level of agreement, and (b) t

Control systems are ubiquitous and often at the core of Cyber-Physical Systems, like cars and aeroplanes. They are implemented as embedded software, that interacts in closed loop with the physical world through sensors and actuators. As a consequence, the software cannot just be tested in isolation. To close the loop in a testing environment and root causing failure generated by different parts of

Popular Abstract in Swedish Det är välkänt att patienter som har gjort ett suicidförsök löper en ökad risk att i framtiden ta sitt liv. I de flesta fall görs suicidförsök av individer som på något sätt är utsatta för stress. Stress kan orsakas av en psykisk eller fysisk sjukdom. Psykosociala faktorer, såsom en skilsmässa eller en annan ohållbar situation i hemmet eller på arbetet, kan också förors

It has been suggested that those organizations which have greatest competitive success are those in which information systems strategy is seen as integral to overall business strategy. Thus, the CIO is seen as a full member of the management team, and not as someone presiding over a separate functional area which provides a service to the rest. There is a need therefore for businesses to avoid suc

European labour markets are often described as rigid with comparatively high levels of job protection that do not allow for the flexible adjustment of employment to economic fluctuations. This interpretation overlooks important sources of flexibility, however. Research has shown that recent labour market policy reforms have allowed for the creation of two-tier labour markets consisting of insiders

Our aim was to compare the predictive accuracy of 4 different medial temporal lobe measurements for Alzheimer's disease (AD) in subjects with mild cognitive impairment (MCI). Manual hippocampal measurement, automated atlas-based hippocampal measurement, a visual rating scale (MTA-score), and lateral ventricle measurement were compared. Predictive accuracy for AD 2 years after baseline was assessed
