Results The study group consisted of 9 men and 9 women, mean age 55 19 years, who had recurrent unexplained syncope for 8 7 years and were subsequently followed up for as long as 14 years (4 4 years on average). The patients had no structural heart disease, standard ECG was normal, and electrophysiological study was negative. In all patients, prolonged ECG monitoring documented paroxysmal compl...

Cystic fibrosis is a genetic disease that typically produces malnutrition and chronic respiratory infections. Prolonged bronchial obstruction, infection, and inflammation result in bronchiectstasis and permanent lung damage. Most cystic fibrosis patients die because of this progressive respiratory disease. Thus, in the absence of a cure, effective respiratory therapy is the primary means to ext...

Permafrost (frozen ground that remains at or below 0◦C for at least two consecutive years) covers 24% of northern circumpolar continents (Zhang et al. 1999). Thawing permafrost in a warming climate can cause hazards of serious concern: (1) Significant amounts of greenhouse gases can be released into the atmosphere due to large-scale microbial decomposition of organic matter that are previously ...

OBJECTIVE The objective of this study was to evaluate a sagittal variation on the lower incisors with the use of the lingual arch on the transition from mixed to permanent dentition. METHODS The sample was constituted of 44 Caucasian patients (26 girls and 18 boys), divided in two groups: CG, control group, monitoring the lower arch space with no orthodontic/orthopedic treatment during the ra...

Objective. Until recently, no objective tool has been available to help health and early childhood education providers screen young children for hearing loss. The aim of this study was to screen underserved children <= 3 years of age for hearing loss using Otoacoustic Emissions (OAE) technology and to systematically document multi-step screening and diagnostic outcomes. Methods. A total of 4519...

Carbon dioxide removal (CDR) appears set to play an increasingly important role in meeting national and corporate net-zero targets. To a credible this effort, CDR must be fungible with fossil CO2 emissions. However, it is clear that non-permanent pathways are of non-zero climate repair value (CRV). In contribution, we present general analytical framework quantifies the CRV pathway arbitrary per...

Condition monitoring and preventative maintenance are essential for reliable efficient operation of permanent magnet synchronous machines driven by inverters. There two types industrial inverter drives available: field oriented control direct torque control. Their compensation nature structure distinct and, therefore, the condition approach designed former may not be applicable to latter one. I...

Spinal cord stimulation (SCS) may be helpful in treating pain and vascular insufficiency associated with inoperable peripheral vascular disease (PVD). Often decision-making regarding progression from trial to implantation is based on subjective measures. Transcutaneous oxygen pressure, a measure of microcirculation and tissue perfusion, provides information on changes that may occur in PVD pati...

From the wide range of methods available to landslide researchers and practitioners for monitoring ground displacements, remote sensing techniques have increased in popularity. Radar interferometry methods with their ability to record movements in the order of millimeters have been more frequently applied in recent years. Multi-temporal interferometry can assist in monitoring landslides on the ...
