Does hepatic visualisation show residual/metastatic thyroid tissue in differentiated thyroid cancer?
(DERMAN MEDICAL PUBL, 2019)
Aim: Diffuse homogen hepatic uptake in whole-body scan (WBS) after radioiodine remnant ablation (RRA) suggests that there is occult or visible remnant thyroid tissue and/or tumor tissue. It is thought that the reason is ...
Unusual mechanical complications of central venous catheterization
(SAUDI MED J, 2019)
Objectives: To present an unusual major mechanical complication of central venous catheterization (CVC). Methods: Between January 2016 and January 2017, data of the patients who underwent CVC in Cumhuriyet University in ...
The physiological and lifespan alterations in Caenorhabditis elegans exposed to different dosages of melatonin
(UNIV KARACHI, 2019)
Aging is a process that begins at birth and ends with death. This process is accompanied by environmental effects, which cause structural and functional changes in cells and tissues. With regards to healthy aging, melatonin ...
Synthesis of tetra-substituted metallophthalocyanines: Spectral, structural, computational studies and investigation of their photophysical and photochemical properties
(PERGAMON-ELSEVIER SCIENCE LTD, 2019)
This work presents the synthesis of peripherally and non-peripherally tetra-substituted metallophthalocyanines (6-14) containing the 2-(3,4-dimethoxyphenyl)ethanol group. The synthesized compounds were characterized by ...
A study of stability and bifurcation analysis in discrete-time predator-prey system involving the Allee effect
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2019)
This paper deals with a discrete-time predator-prey system which is subject to an Allee effect on prey. We investigate the existence and uniqueness and find parametric conditions for local asymptotic stability of fixed ...
A method proposal for monitoring the microclimatic change in an urban area
(ELSEVIER SCIENCE BV, 2019)
It is known that changes in urban surface characteristics lead to different urban climates. The surrounding environment directly affects thermal comfort and human behavior. In this respect, for sustainable urban growth, ...
Examination of Different Communication Topologies for Distributed Control of Multi-terminal HVDC Grids
(INT JOURNAL COMPUTER SCIENCE & NETWORK SECURITY-IJCSNS, 2019)
This paper discusses different communication topologies for cooperative distributed control design of a multi-terminal DC (MTDC) network. In the discussed architecture, the objective of the control design is the DC node ...
Investigations of structural, spectral, electronic and biological properties of N-heterocyclic carbene Ag(I) and Pd(II) complexes
(ELSEVIER SCIENCE BV, 2019)
Computational analyses of two Ag(I) and two Pd(II) complexes were done. Benchmark analyses were performed to obtain the most appropriate calculation level for studied complexes. HF, B3LYP and M062 x method were selected ...
Nonlinear Optical Rectification, Second and Third Harmonic Generations in Square-Step and Graded-Step Quantum Wells under Intense Laser Field
(IOP PUBLISHING LTD, 2019)
For square-step quantum wells (SSQWs) and graded-step quantum wells (GSQWs), the nonlinear optical rectification (NOR), second harmonic generation (SHG) and third harmonic generation (THG) coefficients under an intense ...
Determination of Paragliding Fields with GIS-based Analytic Hierarchy Process
(ISTANBUL UNIV, FAC LETTERS, DEPT GEOGRAPHY, 2019)
Nowadays, people living in the city tend to want to get away from the city. This situation is leading to an ever increasing interest in nature tourism and an orientation to outside sports. One of the most popular nature ...
