The atomic dynamics of linear chains embedded in a crystalline matrix or adsorbed on its surface is studied. A linear chain formed by substitutional impurities in a surface layer and at the same time offsetting from this layer was analyzed particularly. This system models the actively studied experimentally structures…
We have synthesized a new ferromagnetic topological insulator by doping Cr to the ternary topological-insulator material TlSbTe2. Single crystals of Tl_{1-x}Cr_{x}SbTe2 were grown by a melting method and it was found that Cr can be incorporated into the TlSbTe2 matrix only within the solubility limit of about 1%. The…
We study the transmission probability in an AB-stacked bilayer graphene of Dirac fermions scattered by a double barrier structure in the presence of a magnetic field. We take into account the full four bands of the energy spectrum and use the boundary conditions to determine the transmission probability. Our numerical…
Locating new and versatile platform chemicals and biofuels from sustainable resources to replace those derived from petrochemicals is a central ongoing and urgent task prompted by depleting fossil fuel reserves and growing global warming concerns [1-4]. Alternative fine chemicals and biofuels that have been suggested…
The features and efficacies of the procedure of calculated prediction of the working life of reinforced concrete spans of highway bridges are considering in this article, there has been made the analysis of the different proceduresof probable base of margin design and the normative plot of durability has been plotted.
The temperature dependent resistance $R$($T$) of polycrystalline ferromagnetic CoFeB thin films of varying thickness are analyzed considering various electrical scattering processes. We observe a resistance minimum in $R$($T$) curves below $\simeq$ 29 K, which can be explained as an effect of intergranular Coulomb int…
In this paper the results of numerical simulation of monolayer graphene in external magnetic field are presented. The numerical simulation is performed in the effective lattice field theory with noncompact 3 + 1-dimensional Abelian lattice gauge fields and 2 + 1-dimensional staggered lattice fermions. The dependences…
We report on the status of ongoing Hybrid-Monte-Carlo simulations of the tight-binding model of mono-layer graphene. We present results concerning the semimetal-insulator phase transition, whereby two-body interactions are modeled by a partially screened Coulomb potential which takes into account screening by electron…

Сформульовано математичну модель пружнов'язкопластичних деформацій деревини у процесі сушіння, яка враховує пластичні деформації, деформації, зумовлені механіко-сорбційною повзучістю та анізотропією механічних характеристик матеріалу, а також дає змогу визначити двомірний напружено-деформований стан в умовах неізотерм…
Abstract : This report presents the progress we have made on the project Determination of multi-photon absorption spectra: a comparison between transmittance change and fluorescence methods, and refers to the period from November/2013 to February/2015. Initially we present new results on the two-photon absorption cros…
U radu su opisane teorijske osnove lijevanja odljevaka uz naglasak na važnost pravilnog izbora pojila i vrata pojila te njihovog ispravnog pozicioniranja. Opisane su volumne promjene tijekom hlađenja i skrućivanja odljevaka. Obrađeno je sedam pravila napajanja i pet glavnih mehanizama napajanja. Izrađen je CAD model s…
En este proyecto de grado se desarrollaron y caracterizaron recubrimientos polimericos a base de materiales reciclados depositados sobre substratos metalicos, los polimeros reciclados que se utilizaron fueron el ABS, LDPE y UHMWPE, y los substratos metalicos fueron el acero estructural AISI 1020 y el aluminio AISI 436…
Abstract Pb(Zr,Ti)O 3 (PZT)-based ternary system thin films, x Pb(Ni,Nb)O 3 –(1– x )PZT (50/50) (PNN–PZT), are grown on Pt/TiO 2 /SiO 2 /Si substrates using radio-frequency magnetron sputtering system. The intrinsic PZT (50/50) thin films are also deposited for comparison. XRD data display a perovskite structure in PN…
Polyethylene pipes and epoxy or polyurethane linings are increasingly used in drinking water infrastructure. As a recent introduction to the water industry, there are still many unknowns about how polymers will behave in the distribution system specifically relating to sorption and desorption of chemical contaminants.…
Coronary artery anomalies are rare, and single coronary arteries are even rarer occurring 0.024%-0.066% in the general population. They range in presentation from being asymptomatic to severe chest pain and even sudden death. There are numerous variations of Coronary artery anomalies, some benign and others potentiall…

The research and application of organic thin film transistors (OTFTs) made great progress (Zan & Tsai 2012), OTFTs are expected to become the core technology of a new generation flat-panel display. Compared with an inorganic thin film transistor, the OTFT has more advantages, such as more and newer preparation technol…
In solving an engineering problem, such as developing empirical models for manufacturing processes, real data of continuous quantities are required. However, the information and/or data obtained from different sources are often clouded by different kinds of uncertainty. The available data of manufacturing problems are f…
Figure 1 shows the schematic illustration of the model of the ferroelectric thin film with STZ. Si severally denote the lateral size and the thickness. In figure 1 (a), every pseudo-spin layer is comprised of s ( i or Jij ) square loops, and the parameter m represents the site of the each square loop, and st is the su…
