—The effects of electromagnetic coupling on constitutive S-Parameters of bi-anisotropically designed metamaterial (MM) structure with several boundary conditions (PEC, PMC, UC) are analyzed. It is disclosed that in addition to the main electromagnetic coupling effect on the constitutive parameters of resonating MM str…

Magnetic beads with ~1.9 µm average diameter were used to transport microliter volumes of liquids between contiguous liquid segments with a tube for the purpose of investigating phase change of those liquid segments. The magnetic beads were externally controlled using a magnet, allowing for the beads to bridge the air…
This paper presents a robust finite-element procedure for simulating the localised fracture of reinforced concrete members.In this new model, the concrete member is modelled as an assembly of plain concrete, reinforcing steel bar
The dependence of the potential energy [Formula: see text] of Sb atoms on [Formula: see text] symmetry normal coordinates for [Formula: see text] crystal in ferroelectric phase with a varying mixture [Formula: see text] is investigated in the current paper. The potential energy of Sb atoms is characterized by a high a…
[pt] Nanofolhas de ferrititanato com estrutura tipo lepidocrocita foram sintetizadas a partir de um precursor de baixo custo (areia ilmenítica), via rota hidrotérmica alcalina. Dois tipos de nanofolhas com alto e baixo teor de sódio foram obtidos: a) nanofolhas sódicas (NaLTs) e b) nanofolhas protonizadas (pLTs), obti…

Representing massless Dirac fermions on a spatial lattice poses a potential\nchallenge known as the Fermion Doubling problem. Addition of a quadratic term\nto the Dirac Hamiltonian circumvents this problem. We show that the modified\nHamiltonian with the additional term results in a very small Hamiltonian matrix\nwhen…
Title: Impact textile membranes on the dynamics of changes physiological indicators of workload Goals: Compare measurements of clothing technical parameters and laboratory measurement workload in this outfit. Describe and explain the relationship between the results of the technical and functional measurements and phy…
In this work, we have systematically studied structural, electronic and magnetic properties of atomic scale defects in 2D transition metal dichalcogenides MX$_2$, (M = Mo and W; X = S, Se and Te) by density functional theory. Various types of defects, e.g., X vacancy, X interstitial, M vacancy, M interstitial, MX and…
We investigated ecotoxicity and performed experiment for removing ZnO nanoparticles in water. Short term exposure of hatching test using fertilized eggs (O. latipes) showed deformity in 5ppm of ZnO nanoparticles solution. And in 10ppm ZnO nanoparticles solution delayed hatching was observed. Hereine, chemical precipit…
Blood-contacting medical devices rapidly adsorb plasma proteins that initiate clot (i.e. thrombus) formation. Antithrombotic drugs may reduce clotting and associated device dysfunction and ischemia, but put the patient at risk for hemorrhaging. Silicone, a common blood-contacting device material is highly prone to pro…
The acetic acid anhydride hydrolysis is carried out in the adiabatic calorimeter. During reactions the temperature sensor is used to observe changes in temperature, and the data is written in the computer memory at certain intervals. Completion of the reaction is manifested in the termination of temperature growth. Ob…

Beton se dobiva mijesanjem cementa, vode i agregata. U novije vrijeme nemoguce je zamisliti izradu betona bez aditiva i mineralnih dodataka. Mineralnim dodacima za beton smatraju se fino zrnato dispergirani materijali, koji mogu biti dodavani u beton u relativno velikim kolicinama s obzirom na masu cementa (20-100%).…
Research was carried out in order to contribute to the understanding of mechanism of highspeed bonding of calcium aluminate cement (CAC) and development of fast setting and fast curing cement materials. Also, the influence of lithium carbonate on the speed of bonding has been studied. Early initial and high final soli…
This paper examines the influence of alkali metals chlorides, alkaline earth metals chlorides and chlorides of transition elements on setting time of the calcium aluminate cement (CAC) with purpose of manufacturing new cemente composites. Commercial calcium aluminate cement (CAC) 40, manufactured by Istra Cement Inter…
