Thymic cysts are a rare abnormality accounting for 1%–3% of all mediastinal masses.In most cases, they are asymptomatic and localized in the anterior mediastinum.Despite their benign nature, the presence of a mass is an indication for surgery to obtain a histological conclusion Yarrow Flowers and reliably exclude an oncological process.Ep
We study the features of the nonlinear optical response of silver nanoparticles (Ag NPs) of spherical and triangular shapes synthesized using a citrate-borohydride approach and their mixtures with methylene blue (MB+).The Z-scans at the wavelengths of 532 nm using 10 ns pulses were used to analyze the nonlinear optical absorption of MB+ solutions,
Nanofluids are the new developed thermal fluids with enhanced thermophysical properties which can improve heat transfer performance of various applications.By introducing nanoparticles with high thermal conductivity in the car radiator coolant can enhance the effective Socks thermal conductivity of coolant which improves the performance of cooling
This paper deals with weak solution in weighted Sobolev spaces, of three-point boundary value problems which combine Dirichlet and ELM integral conditions, for linear and quasilinear parabolic equations in a domain with curved lateral boundaries.We, firstly, prove the existence, uniqueness, and continuous dependence of the solution for the linear e
In this research, the synthesis of a new azine derivative with coumarin moiety was performed in three reaction steps, starting from 4-hydroxycoumarin.The first step in synthesis was the acetylation of 4-hydroxycoumarin to yield 3-acetyl-4-hydroxycoumarin and then the obtained 3-acetyl-4-hydroxycoumarin was reacted with hydrazine hydrate Parts and g
