In this work we present a multiwavelength study of narrow-line Seyfert 1 galaxies (NLS1s) discovered in the Second Byurakan Survey (SBS). The sample consists of 26 objects, which have MB ≥ −23.0, or −19.9 > MB > −23.0, 0.0243 < z < 0.317 and 15.2 < B < 19.0. For these objects, we present accurate coordinates, magnitudes, redshifts and the identification of optical objects with X-ray, IR and rad...

Background and Aim: Several methods are available for intraoral repair of chipped porcelain restorations by composite resin. Also, there is still controversy regarding the best method of porcelain repair in terms of bond strength and cost effectiveness. This study aimed to compare three methods of porcelain surface treatment on shear bond strength (SBS) of composite to porcelain. Materials a...

The interaction between various municipal solid waste components is very important for the actual treatment process. Microcrystalline cellulose (MC) and styrene–butadiene–styrene triblock copolymer (SBS) are of waste. In this paper, co-pyrolysis characteristics kinetics MC SBS with different heating rates were investigated using a thermogravimetric analyzer. overlap ratio was defined to evaluat...

This study tested the impact of different adhesives and resin composite cements on shear bond strength (SBS) to polymethyl methacrylate (PMMA)- and composite-based CAD/CAM materials. SBS specimens were fabricated and divided into five main groups (n=30/group) subject to conditioning: 1. Monobond Plus/Heliobond (MH), 2. Visio.link (VL), 3. Ambarino P60 (AM), 4. exp. VP connect (VP), and 5. no co...

BACKGROUND The short bowel syndrome (SBS) is a condition caused by extensive intestinal resection for a variety of conditions. The etiology varies by age group. Necrotizing enterocolitis is the leading cause in infants. In older children, trauma and malignancies are most common. Postoperative SBS has become most common in adults, followed by mesenteric vascular disease and cancer/irradiation. ...

This in vitro study compared the shear bond strength (SBS) and adhesive remnant index (ARI) of two systems for bonding orthodontic brackets to enamel. The first system involved a self-etching primer (Beauty Ortho Bond, BO) containing surface pre-reacted glass filler. The second involved a primer applied with phosphoric acid etching (Transbond XT, TX). Ninety-six extracted human premolars were d...

The standard bootstrap (SBS), despite being computationally intensive, is widely used in maximum likelihood phylogenetic analyses. We recently proposed the ultrafast bootstrap approximation (UFBoot) to reduce computing time while achieving more unbiased branch supports than SBS under mild model violations. UFBoot has been steadily adopted as an efficient alternative to SBS and other bootstrap a...

OBJECTIVE Bone loss has been established as a major extra-intestinal complication of short bowel syndrome (SBS). The purpose of this study was to correlate bone mineral density (BMD) with body mass index (BMI), serum vitamin and mineral levels in patients with SBS. MATERIAL AND METHODS The study was conducted on 13 patients (8 male and 5 female, 54.7 ± 11.4 years) with SBS (residual small bow...

The purpose of this study was to evaluate the effect of two different adhesive systems (Tetric Flow and Transbond XT) in combination with fibre-reinforced composites (FRC) net (Ever Stick) on the shear bond strength (SBS) of orthodontic brackets. Eighty bovine permanent mandibular incisors were randomly divided into four equal groups. Stainless steel maxillary central incisor brackets with a 0....
