On the basis of the first law of thermodynamics, an analysis of the orientation of structural interactions was carried out. In the systems in which the interaction proceeds along the potential gradient (positive work), the resultant potential energy is found based on the principle of adding reciprocals of corresponding energies of subsystems there is a corpuscular mechanism. In the systems in which the interactions proceed against the potential gradient (negative performance) the algebraic addition of their masses, as well as the corresponding energies of subsystems is performed there is a wave mechanism. Act of quantum action expressed via Plank’s constant is narrowed to the energy equilibrium-exchange redistribution between the corpuscular and wave processes, that is demonstrated via the angular vector of such motion. Еnergy characteristics of functional states of bio-systems are defined basically by P-parameter values of atom first valence electron. The principles of stationary biosystem formation are similar to the conditions of wave processes in the phase. Under the condition of the minimum of such interactions, the pathological (but not stationary) biostructures containing the molecular hydrogen can be formed. Keywords— potential gradient, corpuscular-wave dualism, Spatial-energy parameter, biosystems, stationary and pathological states.

Simple, accurate and reliable conductometric method for the quantitative determination of Amlodipine Besylate (AML) in pure form and pharmaceutical formulations using sodium tetraphenylborate (TPB) in aqueous solution at 20°C has been described. The method is based on the formation of ion association complex of cation coming from the cited drug with tetraphenylborate anion and the conductance of the solution is measured as a function of the volume of titrant. Many experimental conditions were evaluated. The described procedure allowed the determination of AML in double distilled water in the range of 0.200-1.000mM. The accuracy of the method is indicated by the excellent recovery 98.60-101.40%, and the precision is supported by the low relative standard deviation < 4.74 %. The method was further applied successively to pharmaceutical formulations with no interference from the excipients, the results obtained were compared statistically with those obtained by the official method and showed no significant differences regarding accuracy and precision.

Ferrites, a recently uncovered category of materials, have found extensive application in various critical domains. Among them, cobalt ferrites stand out as hard magnetic materials with exceptional coercivity.. We successfully prepared cobalt ferrites by using nanocrystalline powers by Sol gel method. In our study Crystalline, Magnetic nanoparticles of Cobalt ferrites (Cox Fe1-x Fe2 O4) (x = 0.4, 0.5, 0.6, 0.8) were synthesized by Sol Gel Method using ferric chloride and cobalt nitrate with NaOH as a reactant. Structural characteristics of samples were determined by X-Ray diffraction and TEM. Particle size found between 8.8 nm to 14.26 nm using Debye Scherrer method. Lattice constant decreases as the value of ‘x’ increases. Dielectric properties were investigated using impedance analyser. The relative dielectric constant and loss tangents of ferrites a function of frequency (1kHz-30MHz) was investigated at room temperature, both parameter decreases as frequency increases.

In this article, we studied the past and existing research in nanowire (NW) especially based on SiGe NWs. The basic Thermoelectric (TE) principles and theories are introduced and the factors that may influence the TE performance of SiGe NWs are discussed. The superiority of the group IV material-based NWs as TE materials are detailed with feasible structures while their fabrication methods and TE measurements are also reviewed. The existing SiGe NW are discussed for their potential applications and the feasible applications are illustrated. Finally, the variation of parameter TE on Temperature and carrier concentration is discussed and compare theoretically with the available experimental data.

Generating checklists could provide new insights into the teaching strategies. Thus, the crystal struc-tures’ data of organic compounds learned in secondary chemical education were collected from the Cambridge Crystallographic Data Centre (CCDC) database. It has revealed that almost all the crystal data of these organic molecules are available, contrarily to an anticipation that liquid or gaseous ones at room temperature have few data. This index data would be fundamental for further studies hereafter.
