Power system inertia is an essential part of grid frequency control. The number synchronously connected machines, which inherently provide inertia, decreasing due to the transition renewable energies. Conventional generation units are being replaced by via converters. Some power systems already suffer from too little inertia. Hence, a valuable yet non-traded commodity. A day-ahead dispatch meth...

The authors' aim in this study was to analyze the association of nocturia with overweight and obesity. In 2003-2004, a questionnaire was mailed to 6,000 randomly selected Finns aged 18-79 years who were identified from the Finnish Population Register Centre. Information on nocturia was collected through questionnaires using the Danish Prostatic Symptom Score and the American Urological Associat...

An investigation into the isolability of the location of intake and exhaust manifold leaks in heavy duty diesel engines is presented. In particular, established fault detection and isolation (FDI) methods are explored to assess their utility in successfully determining the location of a leak within the air path of an engine equipped with exhaust gas recirculation and an asymmetric twin-scroll t...

AIMS Resistin is an adipocyte-derived factor implicated in obesity-associated type 2 diabetes (T2DM). This study examines the association between human serum resistin, T2DM and coronary heart disease. METHODS One hundred and fourteen Saudi Arabian patients (male: female ratio 46:68; age 51.4 (mean +/- SD)11.7 years; median and range: 45.59 (11.7) years and BMI: 27.1 (mean +/- SD) 8.1 Kgm2 med...

The distribution and enrichment of naturally occurring radioactive materials (NORM) in coal combustion residuals (CCRs) from different coal source basins have not been fully characterized in the United States. Here we provide a systematic analysis of the occurrence of NORM ((232)Th, (228)Ra, (238)U, (226)Ra, and (210)Pb) in coals and associated CCRs from the Illinois, Appalachian, and Powder Ri...

Pseudoaneurysm is a rare complication of arteriovenous-grafts (AVGs) used in hemodialysis patients. Rupture and bleeding are the most common complications. In this case report, I present the case of a successful repair of an infected pseudoaneurysm that occurred at the AVG, its surgical ligation and the insertion of a new graft segment. Konstantina Triga ( ) Corresponding author: [email protected]...

Two fundamental problems scheduling and routing present themselves in the networking field. Although some ”easy” routing algorithms based upon single constraint optimization exist, we will see that routing with multiple constraints becomes computationally difficult. In order to quantify their intractability, a brief overview of complexity theory will first be presented and then applied to routi...

Infection with an endoparasite frequently alters host behaviour. This study provides the first quantification of larval behaviour in a baculovirus / Lepidoptera system, and attempts to assess the ecological consequences of behavioural modification during infection. Larvae of the moth Mamestra brassicae (Lepidoptera: Noctuidae) exhibited higher rates of dispersal in the laboratory and field when...

For UAS, the removal of the pilot from onboard the aircraft has eliminated the ability of the ground based pilot in command (PIC) to use out-the-window visual information to make judgments about a potential threat of a loss of well clear with another aircraft. As a result, the DAA traffic display will be the primary source of information that the PIC can use to execute the three primary well cl...
