Syncope due to acute rheumatic fever with pacemaker-like syndrome
(2019)
The prolongation in the PR interval on the electrocardiogram is one of the minor criteria of Jones. Abnormal increases in the PR interval lead to hemodynamic impairments caused by atrioventricular asynchrony and is called ...
Low-cost multimode diode-pumped Tm:YAG and Tm:LuAG lasers
(2019)
We report a continuous-wave operation of Tm:YAG and Tm:LuAG lasers pumped with a low-cost, multimode AlGaAs laser diode. First, the lifetime and the absorbance behavior of 5 mm, 6% Tm3+ -doped YAG and LuAG crystals were ...
A rare type of trichotillomania: rhinotillexomania
(2019)
Trichotillomania (or hair-pulling disorder) is a
psychiatric disorder characterized by repetitive chronic
hair pulling that can result in serious hair loss. While
having been familiar for many years, little is known
about ...
Transition coefficients between compressive strengths of samples with different shape and size in mass concrete and use of weight maturity method in dam construction
(Ernst & Sohn, 2019)
Mass concrete (MC) is widely used in dam concretes due to their large aggregate grain diameters, low cement dosage, and low hydration temperatures. Monitoring of the hydration temperature and compressive strength is an ...
Investigation of natural radioactivity and associated radiological hazards in ceramic sanitary ware products commercially sold in Turkey
(Taylor & Francis Ltd, 2019)
All ceramic products used in the construction of buildings contain natural radioisotopes at various rates. These radioisotopes are the main source of outdoor radiation to which people living in houses or workplaces are ...
A numerical analysis of convection heat transfer and friction factor for oscillating corrugated channel flows
(Taylor and Francis Ltd., 2019)
The aim of this article is to understand numerically the flow and heat transfer characteristics under oscillating flow conditions for periodically corrugated wavy channel. For the same channel, under steady-state flow ...
The mechanical compression performance of ultra-fine grained stainless steel pyramidal lattice core
(Taylor & Francis Inc, 2019)
Severe plastic deformation (SPD) techniques are prospective ones having ability for desirable high mechanical properties to be achieved without any chemical change in metals. Equal-channel angular pressing (ECAP), one of ...
Determination of natural radionuclides and some metal concentrations in human tooth samples in the Rize province, Turkey
(Taylor & Francis Ltd, 2019)
The main purpose of this study was to identify the concentrations of naturally occurring radionuclides (Ra-226, Th-232 and K-40) and some metals (Fe, Ni, Cu, Zn, Pb and Cd) in tooth samples collected from humans living in ...
Effects of extractive ammonia pretreatment on the ultrastructure and glycan composition of corn stover
(Frontiers Media Sa, 2019)
Lignocellulosic biomass is highly recalcitrant and requires a pretreatment step to improve the enzyme accessibility and fermentable sugar yields during enzymatic hydrolysis. Our previous studies demonstrated the rearrangement ...
Nedeni bilinmeyen ateş: Tüberküloz ve HIV koinfeksiyonu
(Aves, 2019)
Infections are the most common causes of fever of unknown origin (FUO). Both human immunodeficiency virus (HIV) itself and its concomitant opportunistic infections cause FUO. Clinically, the symptoms and findings are often ...
