Stochastic optimal power flow can provide the system operator with adequate strategies for controlling the power flow to maintain secure operation under stochastic parameter variations. One limitation of stochastic optimal power flow has been that only line flows have been used as security constraints. In many systems voltage stability and small-signal stability also play an important role in constrai

The Lundby study is a classic epidemiological investigation. The first field investigation took place in the parishes of Dalby and Bonderup in 1947. The Lundby population, consisting of 3563 probands, was investigated for the fourth time in 1997 -2000 by Per Nettelbladt and his research team. Previous investigations took place in 1947, 1957, and 1972. Several sources of information have been used,

PURPOSE:: To investigate retinal function and structure after recent-onset rhegmatogenous retinal detachment in relation to type of surgery. METHODS:: Thirteen consecutive patients with rhegmatogenous retinal detachment of <7 days' duration underwent vitrectomy surgery. Optical coherence tomography, full-field electroretinography (ERG), and multifocal ERG were performed preoperatively and 6 months

Cystatin C is believed to prevent tumor progression by inhibiting the activities of a family of lysosomal cysteine proteases. However, little is known about the precise mechanism of cystatin C function in prostate cancer. In the present study, we examined the expression of cystatin C and its association with matrix metalloproteinases 2 (MMP2) and androgen receptor (AR) in a tissue microarray compa

Objectives. RA is associated with joint destruction and cardiovascular diseases (CVDs). Possible predictors for CVD are early changes in body composition. We therefore evaluated whether lean mass of arms and legs (LMAL), total body fat mass (BFM) or truncal fat distribution (TFD) are altered early in RA, and if so, which factors are associated. Methods. We included 132 RA patients (95 women) with

The Counts memorials: A short presentation and interpretation of a number of memorials erected by the count Per Brahe junior between 1653 and 1680 on Visingsö and in Skärstad in Småland, at Dimbo in Västergötland and Östra Ryd in Uppland.

The Golden Ages of Gotland - churches, conjunctures and crusades: A hypothesis which relates the enormous church building on medieval Gotland to an economic boom during the Baltic crusades

The one-dimensional inverse scattering problem is considered for potentials that grow without limit for large values of x. The Marchenko method is established for this class of potentials, and several properties of the solution to the Schrödinger equation are developed. In the derivation of the Marchenko equation an extension of the triangularity condition is used. Some brief remarks on the relati

The purpose of this dissertation is to evaluate the effectiveness and cost-effectiveness of Multisystemic Therapy (MST) in Sweden. This evaluation is set against the background of evidence-based social work practice and is organized around four separate but interrelated studies. The first of these studies used program theory reconstruction to investigate three conceptualizations of evidence-based

Despite recent progress, therapy for metastatic clear cell renal cell carcinoma (CCRCC) is still inadequate. Dysregulated Notch signaling in CCRCC contributes to tumor growth, but the full spectrum of downstream processes regulated by Notch in this tumor form is unknown.

ABSTRACT: BACKGROUND: Medical emigration from developing to developed countries is a well established phenomenon of substantial importance. Though Libya is classified as an upper-middle income country, it has been affected by this trend. This study was undertaken to identify some of the possible reasons behind the emigration of Libyan doctors and factors that might motivate them to return. FINDING
