Abstract: Effect of vacancy formation energy and microhardness on the Debye temperature of some α-phase alloys have been carried out on α-phase (fcc phase) Cu1-x-Znx alloys. The Debye temperatures of α-phase Cu1-x-Znx alloys have been obtained from X- ray integrated intensities. The integrated intensities have been measured with a Philips 3020 powder diffractometer fitted with a proportional counter using filtered CuKα radiation at room temperature and have been corrected for thermal diffuse scattering. The Debye temperatures of these alloys have been estimated from the hardness and are compared with those obtained from specific heats, elastic constants and X-ray intensity measurements.

Abstract: Soil samples were collected from two region Al-anbar (Al-fallujah district) and Wasit of Iraq with an aim to determine the activity concentration using a coaxial high purity germanium (HPGe) detector based on high-resolution gamma spectrometry system. 226Ra, 232Th, the primordial radionuclide 40K, and the artificial radionuclide 137Cs were measured in the soil of the study area. The mean radioactivity concentration in Al-anbar (Al-fallujah district) and Wasit region due to 226Ra, 232Th, 40K, and 137Cs was (20.36, 11.08, 226.97, and 1.01Bq kg-1) and (23.01, 14.45, 290.64, and 2.22 Bq kg-1), respectively. Radium equivalent activity (Raeq), representative level index (Iγ), absorbed gamma dose rate (D) in air, total annual effective dose equivalent (AEDE) from the terrestrial gamma radiation, the external and internal hazard index were estimated. The mean of six hazard index values came out to be (53.67Bq kg-1, 0.38Bq kg-1, 24.78Bq kg-1, 0.15mSv y-1, 0.14Bq kg-1, and 0.19Bq kg-1) in Al-anbar (Al-fallujah district) and (66.17Bq kg-1, 0.49 Bq kg-1, 32.08 Bq kg-1, 0.2mSv y-1, 0.18 Bq kg-1, and 0.24 Bq kg-1) in Wasit, respectively. Present data have been compared with the published data for other regions of the world near from the study area and found to be safe for public and environment.

Abstract: Through a preonic quasi-crystalline quark model, resulted as Bose-Einstein condensate of gammons: g*= (e+e-) and by a pre-quantum cold genesis theory of matter and fields, which predicted the existence of a preon z0 » 34 me experimentally evidenced in 2015, the elementary particles genesis is explained by the cold genesis of two preonic bosons with hexagonal symmetry: zp = 7z0; z2 = 4z0, which explains also the stability of quarks, by a mechanism with a first step of z*/(q± /q0) *- pre-cluster forming by magnetic interaction and a second step of z/(q± /q0)- collapsed cluster forming , with the aid of magnetic confinement, with z = (z0 , z2 , zp) and (q± /q0)- quark or pseudo-quark, resulting some predictions for bosonic dark matter constituents and for multi-quark particles of cold genesis, such as: 2450 me; 2685.4 me tetra-quark; 3063.8 me penta-quark; 2720 me, 3672.4 me hexa-quark; 3329 me, 4762.2 me hepta-quark.

The Theoretic Research of Tachyons with Real Mass: Tachyon Transformation Matrix, Tachyon Oscillations, and Measuring Tachyon Velocity

Abstract: In this paper, a theoretical approach has been used in order to present the physical characteristics of tachyons with real mass. The procedure of the transfer from the Einstein’s physics into the world of superluminal particles has been given. In addition, the tachyon transformation matrix has been constructed using the principle of correspondence between these two physics. With the usage of the tachyon matrix, it has been shown how length contraction and time dilatation are calculated in the tachyons case. A particular attention has been devoted to measuring the velocity of tachyons and their potential flavor oscillations since it should be kept in mind that there is no rest reference frame attached to tachyon world lines and, in that sense, special relativity does not treat tachyons on the same footing as particles that are slower than light. It has been demonstrated, using the Lorentz transformation matrix, that it is impossible to measure the velocities above the speed of light with the method of measuring time of flight in laboratories over a certain distance. It has been particularly disclosed that tachyons as isolated particles each on its own could not exist in nature, and if they did exist, they would always appear united with other tachyon types. Owing to that tachyon characteristic, obtained by theoretical consideration, it has been concluded that tachyons, rather than neutrinos as subluminal particles, could comply with the definition for the occurrence of the oscillation phenomena between different tachyon types. Furthermore, the analysis of the velocity of emitted neutrinos during the explosion of Supernova SN1987A has been conducted in the spirit of the proposed theory, where it has been demonstrated that it is possible to measure even superluminal velocities with the usage of that measuring method.

Observations Concerning the Mass Variation in a Galilean - Type Relativity

Abstract: By an electric charge model of static type, with spherical distribution of field quanta, periodically emitted, and by the Galilean relativity, there are re-obtained the Lorentz’s expressions of the speed-depending longitudinal and transversal mass of a charged particle accelerated by a quanta flux pressure, as apparent effect generated by a real decreasing of the values of longitudinal and transversal electric field, EL ~ g-3; ET ~ g-1, (·g = 1/Ö(1 –v2/c2), being re-obtained also the general form of the Doppler-Fizeau effect. The invariance of the Lorentz force expression indicates a relativist variation of the magnetic field induction, in the form: B ~g-1, which explains the experimental result of the Kaufmann-Bucherer experiments. It is proposed a classical expression of mass and charge variation, in the form: m = mo/a; q = qo/a, (a = (1 – v2/2c2)), which may results as real variation by a significant density of a super-fluid medium of the quantum vacuum containing etherons (mg,s = 10-60¸10-70kg) and quantons (mh = h·1/c2= 7.37x10-51kg), by an relativist etherono-quantonic vortex Gr (v) which is added to the similar vortex Gm (v) of the particle’s magnetic moment which is increased with the speed, if the particle’s spin is rectangular to its impulse. The explicative model may explain also the photon’s energy in correlation with its electromagnetic properties.

The Possibility of Particles Forming from a Bose-Einstein Condensate, in an Intense Magnetic or Gravitational Field

Abstract: In the paper - based on a previous work regarding the cold particles forming process as collapsed cold clusters of gammons- considered as pairs: g* = (e-e+) of axially coupled electrons with opposed charges, is analyzed the possibility of gammons pre-cluster forming from a Bose-Einstein condensate formed in the magnetic and in the gravitational field of a star. By known relations of a BEC forming, it is argued that- in the magnetic field of a star, the forming of a gammonic BEC with particles density N0 corresponding to those of a pre-cluster of gammons which may generates a particle-like stable cluster, may occurs- for a transition temperature TBE » 103K, in a specific interval of field intensity and of temperature: B = (2.2x106 ¸ 8.3x107) T and Tp = (4.8x10-11 ¸ 1.8x10-10) K. The possible mechanism of the formed BEC transforming into pre-clusters of gammons which may become particle-like collapsed BEC, is a pearlitization mechanism, resulted as fragmentation of the formed BEC. It is argued that the particles forming from chiral quantum vacuum fluctuations is possible at T ®0K, either by a vortexial, magnetic-like field corresponding to B ³ 104 T or by already formed gammons, in a “step-by-step” process.
