Adsorption of EDTA on calcite depending on the EDTA concentration and pH of the solution is investigated. It is established that adsorption enhances when decreasing pH of the solution being rather efficiency in neutral media as well. The adsorption efficiency is weakly acidic media makes it possible to solve a problem…
In this work the semi-microscopic vibronic theory of quantum paraelectrics and ferroelectrics of oxide perovskites (SrTi16O3, CaTiO3, SrTi(18Ox16O1-x)3, KTaO3 etc.) has been developed further. It is shown that the electron-lattice couplings of the filled A1g and empty F1u electronic states of the BO6 cluster in ABO3 p…
Anomalous origin of left coronary artery from pulmonary artery (ALCAPA) is rare congenital anomaly. Most of these patients die is infancy. Presentation in adulthood is very rare. Clinical manifestation in teenagers or young adult contains arrhythmia, myocardial perfusion likely causes significant chest pain and these…
Penggunaan plastik tidak bisa lepas dalam kehidupan sehari-hari. Hal ini dikarenakan plastik memiliki sifat unggul seperti: ringan tetapi kuat, transparan, tahan air, serta harganya relatif murah dan terjangkau oleh semua kalangan masyarakat. Limbah plastik banyak dihasilkan setiap tahunnya, namun sedikit yang dapat d…

Solar photovoltaic technology is based on the direct conversion of solar radiation power into electrical power by means of solar cells. Photovoltaics can in principle play a major role in the search for alternative energy sources, even though it is still not competitive with respect to traditional sources, e.g. based…
El desarrollo del ciclo de combustible del Th comienza con la implementacion de combustibles Th/Pu MOX, combustible mezcla de oxidos de Th y Pu, en reactores termicos. La finalidad es conseguir experiencia relacionada con las tecnologias del Th (fabricacion, irradiacion y reprocesado del combustible irradiado), asi co…
Un gran numero de las propiedades que presentan los materiales polimericos dependen, casi en exclusiva, de su superficie. Para estas, es independiente de como sea el interior del material y su aplicabilidad solo se va a ver afectada por las capas mas externas, las ultimas micras superficiales. Por todo ello, el diseno…
The technique of time dependence identification for non-stationary influence distributed on known area of a constructive element with complex geometry, using values of variable which is more accessible to measurements is presented.In the assumption that reaction of an element linearly depends on the influence the cons…
Abstract : This report summarizes results supported by grant no. FA9550-12-1-0190. We report: 1. Development of new n-type dopants 2. Design rules and synthesis of high performance n-doped conducting polymers; 3. Fundamental understanding of organic semiconductors through tuning molecular packing and morphology; 4. St…
The paper studies core type transformers, in which radial and axial electromagnetic short circuit forces act upon winding coils. In the conductors, these forces cause stresses due to bending in the radial and axial directions, as well as tensile or compressive stresses. Due to plastic deformations originating in the w…
Brassica napus is a commercially important crop worldwide and its use is quickly increasing due to its beneficial oil products and biofuel demands. Yield can be lost through infection by a fungal pathogen, Leptosphaeria maculans, the causal agent of stem canker (blackleg). An early indication of the presence of stem c…
In this Special Section, nine papers from the German Research Foundation (DFG) Research Training Group 1229 “Stable and Metastable Multi-Phase Systems for Elevated Service Temperatures” have been collected. High-temperature materials are of extremely high technical and economic interest. They play a major role in engi…

An outline of the Timoshenko beam theory, which deals with deflection and cross-section rotation as the basic variables, is presented. It is modified by decomposing total deflection into pure bending deflection and shear deflection, and total rotation into bending rotation and axial shear angle. The governing equation…

Cells contain a network of protein filaments called microtubules. These filaments are involved in many biological processes; for example, they help cells keep the right shape, and they help to transport proteins and other materials inside cells. Two proteins called α-tubulin and β-tubulin are the building blocks of mi…
The electron-phonon coupling in non-equilibrium aluminium was investigated experimentally and by \textit{ab initio} theory. The temporal evolution of the atomic mean squared displacement in the laser-excited thin free-standing film was monitored by femtosecond electron diffraction. The electron-phonon coupling strengt…
The properties of artificially grown thin films are often strongly affected by the dynamic relationship between surface growth processes and subsurface structure. Coherent mixing of X-ray signals promises to provide an approach to better understand such processes. Here, we demonstrate the continuously variable mixing…
