High-resolution images of 7 newly identified BL Lac objects (among them one BL Lac candidate) at z ≤ 0.2 from the Einstein Slew Survey are presented for the first time. In all cases we were able to resolve the host galaxy. Our 2−dimensional analysis of the host galaxies shows that all these BL Lac objects are embedded in elliptical galaxies with an average MR = −23.1 and re = 10 kpc. One BL Lac...

background and aims. due to anatomic variation in tooth anatomy between populations, this study compared the buccolingual (bl) and mesiodistal (md) dimensions of primary molars with those of stainless steel crowns (sscs) in an iranian population. materials and methods. impressions were taken from both dental arches of children, and casts were poured. teeth with caries, restoration, hypoplasia o...

research has shown that shift work, in particular night work, can have negative effects on the health, safety and well-being of workers. our study assessed, in a hospital setting, the effects of bright light (bl) on general health and psychological problems during night shift work. in an experimental design, 15 female nurses at a general hospital that located in tehran were exposed to moderate ...

BACKGROUND The battery life (BL) of portable home ventilator batteries is reported by manufacturers. The aim of this study was to evaluate the effects of ventilator mode, breathing frequency, PEEP, and leaks on the BL of 5 commercially available portable ventilators. METHODS The effects of the ventilator mode (volume controlled-continuous mandatory ventilation [VC-CMV] vs pressure support ven...

A distinctive physical property of bulk water is its rich solid-state phase behavior, which includes 15 crystalline (ice I-ice XIV) and at least 3 glassy forms of water, namely, low-density amorphous, high-density amorphous, and very-high-density amorphous (VHDA). Nanoscale confinement adds a new physical variable that can result in a wealth of new quasi-2D phases of ice and amorphous ice. Prev...

we prove that rs-bl-algebras are mv-algebras.
