An electromagnetic material is categorized by its constitutional parameters, permittivity ε and permeability μ. A double-positive (DPS) material is defined as a right-handed (RH) material. The phase constant of wave propagation within the RH material exhibits a positive value. A double-negative (DNG) material is defin…
The temperature evolution of GdFeCo electrons following optical heating plays\na key role in all optical switching of GdFeCo and is primarily governed by the\nstrength of coupling between electrons and phonons. Typically, the strength of\nelectron-phonon coupling in a metal is deduced by monitoring changes in\nreflect…
Biodegradable material such as poly(lactic acid) (PLA) can be generated with great control of polymer molecular weight and dispersity using a large range of metal-based catalysts. PLA is generated from the ring-opening polymerization of cyclic ester lactide, either biologically derived L-lactide or racemic lactide, us…
In this paper we consider the branched transportation problem in 2D associated with a cost per unit length of the form $1 + αm$ where $m$ denotes the amount of transported mass and $α> 0$ is a fixed parameter (notice that the limit case $α= 0$ corresponds to the classical Steiner problem). Motivated by the numerical a…
Granular materials are ubiquitous in nature and technology. Nevertheless, no macroscopic equation for granular materials is known. The discrete element method (DEM) has been widely used to simulate complex behavior of granular materials without constitutive laws. It has become increasingly clear that the dynamics of n…
Basic and advanced concepts of ligand design in modern lanthanide non-aqueous chemistry are considered to rationalize progress in this field in the last 50 years. Major advances are illustrated with selected examples, which are divided into C-, N- and P-donor ligands. These landmark results include the stabilization o…

To investigate electrical properties of conducting polypyrrole (PPy) and cobalt aluminum oxide (CAO) nanocomposites, impedance analyzer in frequency range of 100 Hz to 5 MHz is used. In this work, PPy/CAO nanocomposites were synthesized by chemical oxidation polymerization method in different weight percent of CAO in…

Mesenchymal stem cells (MSC) are capable of self renewing and differentiating into other cell types. Human umbilical cord blood (HUCB) has been investigated as an alternative source to bone marrow. The aim of our examinations was to investigate MSC of HUCB could differentiate into keratinocytes under in vitro conditio…

Usually, phosphate deposits contain 238U and 232Th in addition to their decay products. Due to their different pathways in the environment, the 238U/232Th activity concentration ratio usually found to be greater than unity in phosphate sediments. The presence of these radionuclides creates a potential need to control…

Bunlarin en onemli sinifini Sekil Hafizali Alasimlar (SHA) olusturur. Uygun termomekanik islemler gerceklestirildi…
Abstract Corrosive behavior in reinforced concrete specimens containing two agricultural byproducts, rice husk ash, and water extracted from manioc, called mandioca brava in Brazil, was investigated by accelerated corrosion tests in a modified immersion assay. The rice husk ash and mandioca brava were characterized by…
100 nm thick RuMoC films and 5 nm thick RuMoC films with Cu capping have been deposited on Si(111) by magnetron co-sputtering with Ru and MoC confocal targets. The samples were subsequently annealed at temperatures ranging from 450 to 650 °C in vacuum at a pressure of 3 × 10−4 Pa to study the annealing effects on the…
In the paper the planar waveguide based on SU-8 polymer were made on different substrates. As polymer layer Gerseltec SU8 GM1040 and Microchem SU8 2000.5 were used. By using Gerseltec SU8 GM1040 we obtained layer with thickness 950 nm which gave us planar waveguide bimodal structure for λ=633nm. By using Microchem SU8…
В работе проанализированы проблемы, связанные с определением размеров кластеров в неупорядоченных (аморфных, жидких и нанокристаллических) материалах. Описаны способы определения размеров кластеров по данным дифракционного эксперимента. Показано, что на данный момент точного метода определения этого параметра пока не…
Під нашим спостереженням знаходилися 107 пацієнтів із наслідками поліструктурних ушкоджень передпліччя і кисті. У 53,3 % хворих була встановлена група інвалідності, в більшості випадків це були інваліди III групи — 47,7 %; II група встановлювалася у 5,6 % випадків. Систематизація виявлених порушень дозволяє визначити…
Tekstil boyama endüstrisinde kullanılan Bazik Mavi 3 boyarmaddesinin alüminyum elektrot kullanılarak elektrokimyasal olarak tekstil atık sularından giderimi üzerinde çalışılmıştır. Kesikli proses ile yapılan deneyler sonrasında 10 dakika sonunda pH8 değerinde %97’den fazla giderim etkinliği hesaplanmıştır. Elektrokimy…
In this work, heavy metal oxide glasses based on Bi2O3–GeO2–Ga2O3–Na2O system have been synthesized under a low vacuum conditions. This procedure reduced absorption band at 3 μm due to OH- ions concentration decrease to 50 ppm. Glass has been characterized by low phonon energy (724 cm-1), low absorption coefficient in…
