Where is the Time Arrow Flying?  [PDF]
Vladimir I. Konushko
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.27074
Abstract: Irreversible phenomena embrace all bodies of the physical world and the entire Universe on the whole, they introduce development to the Universe setting the motion and the pace to time. The latter is flowing just in one direction, from the past to the future, and no physical action can turn it back. Why is such an asymmetry? In this work the relation between entropy and granular spatial structure is established and the cause of the irreversibility of physical processes is thereby settled. The concept of time filled with a new physical meaning.
A Model for a Spherically Symmetric Space Generated by a Spherical Gravitational Source and a Gravitational Medium with Constant Mass Density  [PDF]
Nikolaj N. Popov, Vladimir I. Tsurkov
International Journal of Astronomy and Astrophysics (IJAA) , 2013, DOI: 10.4236/ijaa.2013.32A004
Abstract:

A metric on a spherically symmetric space generated by a spherical source of gravity and filled with a gravitational medium is constructed, and criteria for the continuity of this metric on the entire space (which is equivalent to the absence of black holes) are found. Properties of radial geodesics under various constraints on the size of the gravitational source, its mass, and the mass density of the gravitational medium are studied.

Generation and Detection of a Directed Monoenergetic Neutrino Beam with Hydrogen-Like Ions  [PDF]
Lorcan Michael Folan, Vladimir I. Tsifrinovich
World Journal of Nuclear Science and Technology (WJNST) , 2017, DOI: 10.4236/wjnst.2017.71005
Abstract: We consider two possible schemes for generation and detection of a monoenergetic directed beam of neutrinos which may have application to neutrino communication. First, we consider generation of a directed neutrino beam using electron capture beta decay in hydrogen-like ions. Next, we suggest detection of a directed neutrino beam using resonant absorption of a neutrino by a bare nucleus with the generation of a bound electron. This reaction is inverse to electron capture beta decay, and we call it “Bound State Inverse Beta Decay (BSIBD)”. We show that the recoil effect can be eliminated by an appropriate choice of velocities for the ions and bare nuclei. Finally, we consider a combination of a solid state source of a directed mono-energetic neutrino beam and its detection using BSIBD.
La comunidad de copépodos (Crustacea) en los giros a mesoescala en el occidente del Golfo de México (julio, 1995)
López-Salgado,I.; Gasca,R.; Suárez-Morales,E.;
Revista de Biología Tropical , 2000,
Abstract: the pelagic copepod community of the oceanic area off the mexican state of tamaulipas was surveyed in june-july 1995. during the period and area surveyed, two mesoscale gyres, a cyclone and an anticyclone, were detected. the influence of each was related to a particular area. a total of 106 copepod species was determined. copepod density, diversity, and species richness differed between the areas affected by the cyclone and the anticyclone. the overall density in the two areas was similar, but copepods at the cyclone nucleus were slightly denser than in the anticyclonic nucleus. diversity and species richness were higher at the relatively more productive cyclone area. anticyclones are oceanic, oligotrophic systems with a strong caribbean influence, and the local copepod community structure, dominated by some of the most abundant species in the caribbean, and with relatively lower diversity and species richness, seemed to agree with the anticyclone features. the copepod fauna of the cyclone, mainly built up by common gulf water, showed a higher diversity and species richness, and a higher affinity with the fauna of the gulf. the distributional range of several species is extended in this survey and some are reported herein for the first time in the gulf of mexico.

Abstract: Se estudió la comunidad de copépodos pelágicos en la zona oceánica frente Tamaulipas, Mexico durante junio-julio de 1995. En este periodo se detectaron dos giros a mesoescala, uno ciclónico y el otro anticiclónico; su influencia se relacionó a zonas distintas del área de estudio. Se identificaron 106 especies de copépodos; su densidad, diversidad y riqueza de especies varió entre las áreas afectadas por el ciclón y el anticiclón. La densidad general fue similar en los dos sistemas, pero se encontró mayor densidad en el núcleo del ciclón que en el del anticiclón. La diversidad y el número de especies fue mayor en el ciclón, un sistema más productivo. Los anticiclones son sistemas oceánicos, oligotróficos, con aguas del Mar Caribe. La comunidad de copépodos en este giro, dominada por algunas de las más abundantes especies caribe as, y con una diversidad relativamente menor, tiene más afinidad con las condiciones anticiclónicas. La fauna del ciclón, formada con aguas comunes del Golfo, mostró mayor diversidad y riqueza de especies así como una afinidad cualitativa mayor con la fauna propia del Golfo. El ámbito de distribución de varias especies se extiende en este estudio; para otras, representa el primer reporte para el Golfo de México.

Rotation of PRODAN in excited state
Vladimir I. TOMIN
Optica Applicata , 2006,
Abstract: Instant spectra and anisotropy kinetics of PRODAN luminescence in different ranges of spectra has been studied upon excitation by picosecond pulses. Instant spectra of luminescence reveal time dependent Stokes shift having intermolecular nature as its characteristic time correlates with dielectric relaxation time of solvent. The mean Brownian rotation time for the curves obtained shows complex character of spectral dependence with maximum ~39 ns near maximum of luminescence intensity and drops down to 15 ns on the edges of the spectrum. An explanation is based on a treatment of intermolecular energy conversion into thermal movement of molecules during relaxation in excited state. Calculations using hydrodynamic model show “stick” boundary conditions for solutes: rotational volumes correspond to solute together with molecules of the first coordinative sphere filled by solvent.

Abstract: Osnovni postupak pridobivanja PS-E-a je suspenzijska polimerizacija stirena. U tom je postupku organska faza (stiren monomer) suspendirana u vodi u obliku kapljica. Stabilnost suspenzije ovisi o raznim faktorima: isto i sirovina i aditiva, brzini polimerizacije, omjeru monomera i vode, brzini vrtnje mije alice, geometriji reaktora i dr. U radu se opisuje tehnologija dobivanja PS-E-a u DIOKI-ju jednostupnjevitom polimerizacijom baziranom na tehnologiji PSTW (SAD). / Suspension polymerization of styrene is the main process for PSE production. In this process organic phase (styrene monomer) is suspended in water phase as droplets. Stability of suspension depends on various factors: purity of raw materials and additives, polymerization reaction rate, ratio monomer/water, mixing speed, reactor geometry and other. The paper describes production technology for PS-E in DIOKI with one step production based on PSTW technology (USA).

Abstract: With the death of professor Edvard Ravnikar, Slovenia has lost the central figure of architecture, urban planning and the founder of the first school of urban design. Some of his projects, which are turning points for modern Slovene urban planning and design are presented, among other, the competition project for the regulation for Ljubljana, the project for the transformation of villages, projects for Nova Gorica, Kranj and Kidri evo, as well as projects carried out by students under his mentorship.
