During the iron ore sintering process, its SiO2 content considerably affects sinter quality. In this study, effect of on indexes was studied, with mineral composition and microstructure analyses. It shown that strength reducibility products improved when increased. The yield tumbler index increased from 69.57% 58.67% to 74.02% 62.32%, respectively, increasing 3.92% 5.12%. Moreover, reduction di...

INTRODUCTION The aim of this study was to assess results of 6MWT in non-selected group of obstructive sleep apnoea (OSA) patients. In healthy adult subjects 6-minute walking distance (6MWD) range from 400 to 700 m. Obesity, the main symptom of OSA, is one of the factors associated with reduction of 6MWD (another common factors: older age, shorter height, female sex, pulmonary, cardiovascular an...

AIMS Previous studies have identified four baseline characteristics associated with a favourable response to cardiac resynchronization therapy (CRT): female, non-ischaemic aetiology of heart failure, left bundle-branch block (LBBB), and QRS duration ≥150 ms. This study evaluated the incremental value of discoordination and dyssynchrony indices over these characteristics for the prediction of th...

A Robust Dynamic Inversion (RDI) ight control law is designed for a large civil aircraft. Classical Dynamic Inversion (CDI) consists of a nonlinear part that linearizes the nominal system dynamics, and a linear part, basically PID control, that imposes the desired closed-loop dynamics. However, CDI controllers have very poor robustness properties since they rely on exact availability of the sys...

BACKGROUND Research has shown micronutrient deficiency to be scientifically linked to a higher risk of overweight/obesity and other dangerous and debilitating diseases. With more than two-thirds of the U.S. population overweight or obese, and research showing that one-third are on a diet at any given time, a need existed to determine whether current popular diet plans could protect followers fr...

STUDY OBJECTIVES To evaluate the validity of the Apnea Risk Evaluation System (ARES) Unicorder, a self-applied, limited-channel portable monitoring device for the evaluation of sleep disordered breathing (SDB). DESIGN Prospective study with blinded analysis. SETTING Sleep disorder center, academic institution. PARTICIPANTS Eighty patients with suspected obstructive sleep apnea hypopnea sy...

Purpose This study aims to determine how sustainable development (SD) demands (according the United Nations Economic Commission for Europe’s (UNECE) SD themes from 2005) are connected contents of education, research, and innovation (RDI) in higher education institutions (HEI). Education RDI nexus may affect HEI’s capability handle SD-related wicked problems enhance their societal impact. Design...

This research studies the potential impact of climate change on future trend and changes of two well known drought indicators namely RDI and SPI in Yazd meteorological station, in central part of Iran. For this purpose, data of HadCM3 model that were resulted from GCM-runs based on the IPCC-SRES scenarios of A2 and B2 were acquired and analyzed for projection of daily Tmin, Tmax and precipitati...

IMPORTANCE Maxillomandibular advancement (MMA) is an invasive yet effective surgical option for obstructive sleep apnea (OSA) that achieves enlargement of the upper airway by physically expanding the facial skeletal framework. OBJECTIVE To identify criteria associated with surgical outcomes of MMA using aggregated individual patient data from multiple studies. DATA SOURCES The Cochrane Libr...
