A new approach to determine maintenance periods of the most critical hydroelectric power plant equipment
(ELSEVIER SCI LTD, 2021)
Power plants are large-scale generation facilities with high investment costs established to ensure sustainable energy supply. Maintenance-Repair activities constitute the most critical process to be considered in these ...
An updated tribal classification of Lamiaceae based on plastome phylogenomics
(BioMed Central Ltd, 2021)
Background: A robust molecular phylogeny is fundamental for developing a stable classification and providing a solid framework to understand patterns of diversification, historical biogeography, and character evolution. ...
Modification of halloysite clay nanotubes with various alkyl halides, and their characterization, blood compatibility, biocompatibility, and genotoxicity
(Elsevier Ltd, 2021)
Halloysite nanotubes (HNTs) clay were modified with alkyl halides, bromoethane (BrE), bromodecane (BrD), and bromooctadecane (BrOD), respectively. The FT-IR spectra of modified HNTs demonstrated an increase in the intensity ...
Mechanical and microstructural characterization of geopolymers from assorted construction and demolition waste-based masonry and glass
(Elsevier Ltd, 2021)
Geopolymers are mostly produced with main-stream precursors such as fly ash and slag. These precursors are successfully used and competitively demanded by the cement industry. Development of geopolymers from alternative ...
Synthesis, characterization and wound healing ability of PET based nanofiber dressing material coated with silk sericin capped-silver nanoparticles
(Elsevier Ltd, 2021)
In this study, silver nanoparticles coated with sericin (S-AgNPs) were adsorbed on poly (ethylene terephthalate)-g-poly(hydroxyethylmethacrylate) (PET-g-HEMA) nanofibers and the use of the obtained material as wound dressing ...

(Elsevier Ireland Ltd, 2021)
Objectives: The objectives of the present study were to evaluate the vestibular impairment in children with acute otitis media (AOM) and dizziness by using video head impulse test (vHIT) and to compare their results with ...
The chemical activity of Juglone in different phases as a protective agent
(Elsevier B.V., 2021)
Juglone has a powerful antioxidant and antimicrobial effects due to the main active phenolic compound in the leaves and shell of a walnut. The aim of the current investigation is to determine the effect of Juglon (5-Hydroxy, ...
Approximation of Some Classes of Functions by Landau Type Operators
(Birkhauser, 2021)
This paper aims to highlight a class of integral linear and positive operators of Landau type which have affine functions as fixed points. We focus to reveal approximation properties both in Lp spaces and in weighted Lp ...
Fracture load and microcrack comparison of crowns manufactured from tooth-shaped and traditional blocks
(WILEY, 2021)
This study intended to analyze microcracks and fractographic markings on the surface of all ceramic crowns after milling and compare the fracture loads. 90 crowns were manufactured from two feldspathic (Priticrown-Pr and ...
On generalized null Mannheim curves in E24
(WILEY, 2021)
In the present paper, we introduce the notion of Cartan-framed generalized null Mannheim curves in four-dimensional semi-Euclidean space with index 2, E24. We obtain the Cartan (or Frenet) frames and curvature functions ...
