Maser is an acronym for microwave amplification by stimulated emission of radiation; in astronomy mega-masers are masers in galaxies that are ≥ 10(6) times more luminous than typical galactic maser sources. Observational studies of mega-masers can help us to understand their origins and characteristics. More importantly, mega-masers can be used as diagnostic tracers to probe the physical proper...

Methods “Papageorgiou” General Hospital is one of the four major hospitals of Thessaloniki, the second largest Greek city of 1.2 million inhabitants. Data was extracted from hospital databases (ICD-10 diagnoses V01-V89 for MT and X60-X84 for SA) from the year 2008 to 2014. Several variables concerning patient demographics, APACHE and SAPS II scores, length of ICU stay (LOS) and outcome were rec...

PURPOSE The most common γ-aminobutyric-acid (GABA) editing approach, MEGA-PRESS, uses J-editing to measure GABA distinct from larger overlapping metabolites, but suffers contamination from coedited macromolecules (MMs) comprising 40 to 60% of the observed signal. MEGA-SPECIAL is an alternative method with better MM suppression, but is not widely used primarily because of its relatively poor spa...

Recently, the incidence of Takotsubo cardiomyopathy (TTC) has been estimated to be 29.8 per million inhabitants [1]. TTC has been recognized since 1990 and is characterized by chest pain, the elevation of cardiac markers, dynamic ECG changes characterized by negative T-waves [2] or mimicking ST-segment elevation myocardial infarction in some cases, transient apical and mid-ventricular wall-moti...

The kingdom of Denmark (excluding Greenland and the Faeroe isles) covers 43 080 square kilometres between 55 and 58 degrees north and 8 and 12.5 degrees east. The population on 1 January 1986 was 5.1 million. The medical care system is organized into a private sector of general practitioners and specialists under contract with the National Health Insurance, and a public sector operating hospita...

The earned value technique is a crucial and important technique in analysis and control the performance and progress of mega projects by integrating three elements of them, i.e., time, cost and scope. This paper proposes a new version of earned value analysis (EVA) to handle uncertainty in mega projects under interval-valued fuzzy (IVF)-environment. Considering that uncertainty is very common i...

In this study, a minimal submaximal element of LIT(X) (the lattice of all intuitionistic topologies for X, ordered by inclusion) is determined. Afterwards, a new contractive property, intuitionistic mega-connectedness, is defined. We show that the submaximality and mega-connectedness are not complementary intuitionistic topological invariants by identifying those members of LIT(X) which are int...

In this article, a four-phase dual armature-winding wound-field doubly salient machine with distributed field magnetomotive forces (DAW-WFDSM-DF) and corresponding double-redundant rectifier circuit are proposed to improve the electromagnetic performance of traditional WFDSM in terms output voltage ripple, fault-tolerant capability capability. Firstly, due uniformly machine, more feasible stato...

Background Pre-hospital advanced airway management has been named one of the top-five research priorities in physician-provided pre-hospital critical care [1]. Few studies have been made on paediatric pre-hospital advanced airway management. The aim of this study was to investigate first-pass success rates and complications related to pre-hospital advanced airway management in patients younger ...
