Abstract:

Variational principle plays a fundamental role in elucidating the structure of classical mechanics, clarifying the origin of dynamics and the relation between symmetries and conservation laws. In classical mechanics, the optimized function is characterized by Lagrangian, defined as T-V with T and V being a kinetic and a potential terms, respectively. We can still argue a variational principle even in quantum mechanics, but the Lagrangian does not have the form of T-V any more. Therefore, at first glance, any clear or direct correspondence between classical and quantum mechanics does not seem to exist from the variational point of view, but it does exist. For this, we need to extend the usual variational method to the case of stochastic variables. This is called stochastic variational method (SVM). The Schrödinger equation can be then obtained by the stochastic optimization of the action which leads to, meanwhile, the Newton equation in the application of the classical variation. From this point of view, quantization can be regarded as a process of stochastic optimization and the invariance of the action leads to the conservation laws in quantum mechanics. In this manner, classical and quantum behaviors are described in a unified way under SVM. Although SVM was originally proposed as the reformulation of Nelson's stochastic quantization, its applicability is not restricted to quantization. In fact, dissipative dynamics such as the Navier-Stokes-Fourier (viscous fluid) equation can be obtained by applying SVM to the Lagrangian which leads to the Euler (ideal fluid) equation in the classical variational method. This method is useful even to obtain coarse-grained dynamics. For example, the Gross-Pitaevskii equation is regarded as an optimized dynamics in SVM. Therefore it is possible to consider that the study of SVM enables us to generalize the framework of analytic mechanics.

Abstract:

Remedial actions are necessary in environments with high radon concentrations. A first survey about measurements of indoor radon concentration in working places was performed in Extremadura (Spain). Sites studied included resorts, spas, caves, tunnels, mines, facilities storing or dealing with water, and other underground and surface suspected work places (warehouses, parking lots, hotels, museums, educational centres, etc.). Results showed that about 85% of more than 300 working places measured, were below an annual average concentration of 200 Bq/m3, 9% were between 200 and 400 Bq/m3, and 6% were above 400 Bq/m3. A second study was undertaken, performing surveillance and applying mitigation methods when necessary. Four surveys were performed to fulfil one year study. Remedial or mitigation actions (ventilation, changing the working place inside the same building, limiting the time of residence of people, or architectonics actuations) were applied. A total of 240 measurements were performed in 35 sites. At this time, following the actual Spanish legislation, the working places were classified as 191 results (in 26 sites) with average indoor radon concentration lower than 600 Bq/m3, 38 results (in 6 sites) between 600 and 1000 Bq/m3, and 11 results (in 3 sites) with concentrations above 1000 Bq/m3. In some special cases, a continuous monitoring device was used to study the hourly variation of the indoor radon concentration. Results showed then a very great variability. Concentration variations in the working day and journey should be considered in this case because otherwise the dose received by workers could be erroneously estimated.

Galina Yakubova

USDA-Agricultural Research Service, USA

Title: Application of the pulsed fast/thermal neutron method for soil elemental analysis

Time : 10:50-11:15

Speaker
Biography:

Galina Yakubova has experience in the field of Applied Nuclear Physics during 20 years. She has completed her PhD in 2009 year from University of Illinois at Urbana-Champaign, and Post-doctoral studies from Brookhaven National Laboratory. She is a Soil Nuclear Scientist at NSDL and works at application of nuclear physics methods for soil elemental analysis. She published 4 papers on present topic in reputed journals, and had 3 presentations on National and Regional conferences.

Abstract:

Soil science is a research field where physical concepts and experimental methods are widely used, particularly in agro-chemistry and soil elemental analysis. Different methods of analysis are currently available. The evolution of nuclear physics (methodology and instrumentation) combined with the availability of commercial products (portable pulse neutron generators, high efficiency gamma detectors, reliable electronics, and measurement processing software) and the current understanding of neutron interactions with nuclei, has recently made it possible for neutron-gamma analyses of soil elemental content for routine field measurements (cropland, forest, desert etc.) as well as in the laboratory. Neutron-gamma analyses are based on the registration of gamma lines which appear due to neutron-nuclei interactions. These methods have great advantage over traditional chemical (dry combustion) and physical-chemical methods which are labor extensive and time consuming. Neutron-gamma analyses are non-destructive multi-elemental analyses of large soil volumes that require no sample preparation, and are conducted in situ. We will discuss physical principals, apparatus design, and application of an advanced of neutron-gamma approach [i.e., Pulsed Fast/Thermal Neutron Method (PFTNA)] for soil elemental analysis. Using examples of this method for soil carbon, nitrogen, and chlorine determination, we will demonstrate the main features and possible use of PFTNA for the analyses of nuclei having characteristic gamma lines issued due to inelastic neutron scattering and for nuclei having characteristic gamma lines issued due to thermal neutron capture.

Abstract:

We present two alternative expansion scheme called Floquet-Magnus expansion used to solve a time-dependent linear differential equation which is a central problem in quantum physics in general and solid-state nuclear magnetic resonance (NMR) in particular. The commonly used methods to treat theoretical problems in solid-state NMR are the average Hamiltonian theory and the Floquet theory, which have been successful for designing sophisticated pulse sequences and understanding of different experiments. The topic of the talk opens a way to an infinite number of suggestions. However, it is very important to remember that the Fer and Floquet-Magnus expansions method have recently found new major areas of applications such as topological materials. Researchers, dealing with those new applications, are not usually acquainted with the achievements of the magnetic resonance theory, where those methods were developed more than 30 years ago. They repeat the same mistakes that were made when the methods of spin dynamics and thermodynamics were developed in the past. This talk is very useful not only for the NMR and physics communities but for the new communities in several younger fields. It will be very useful for scientists working in different directions. In this talk, I will compare both approaches (Fer and Floquet-Magnus expansions) and present their use for the calculation of effective Hamiltonians and propagators, the performance of explicit calculation for the Bloch-Siegert shift, heteronuclear dipolar decoupling, cross-polarization, and rotary-resonance recoupling. This presentation contributes theoretically and numerically in the general field of spin dynamics and physics.

Mehdi Nosrati

University of Alberta, Canada

Title: Magnetic current and new modifications of Maxwell’s equations

Time : 12:25-12:50

Speaker
Biography:

Mehdi Nosrati received the M.S degree in electrical engineering from Tarbiat Modares University, Tehran, Iran, in 2006. He was lecturer for 4 years in the university. He has been starting his Ph.D program from Sept. 2011 in the University of Alberta. His current research interest includes microwave and millimeter-wave components. Integrating MEMS actuator with waveguide structures to design tunable microwave components is the main part of his research as the Ph. D student. Moreover, his personal research interests include the nature of electromagnetic waves and Maxwell’s equations.

Abstract:

Maxwell’s equations are the main foundation of the current communication technology; however, they are still incomplete with some ambiguities and unknown parameters. Magnetic current is apparently the main missing part of these equations [1]. In this talk, we resolve to revise these equations and the conventional definitions of the terms and parameters from the beginning merely based on logical theory to justify all measurements so far. These revisions will be initiated by modifying Bohr’s Model and physical differentiations of magnetic and electrical fluxes to justify all electromagnetic phenomena under a consistent umbrella. Consequently, we can theoretically present a rational illustration of magnetic current and amend the contradictions and inconsistencies in the current models and theory of electromagnetic waves. As given in current Maxwell’s equations given in (1)-(2), these equations are not balanced where the right sides of these equations consist of two Equ. (1) and three components Equ.(2). Few researches have been theoritically done in the literature to find this missing term where it has been defined as a multiplication of a coefficient by magnetic field. While this definition mathematically provides a substantial model of this missing term, it does not discuss the physical interpretation of the used coefficient in the definition.
