Sidereal anisotropy of cosmic rays

The data of the ionization chamber in Yakutsk for 1954 to 1984 are analyzed. A false sidereal variation caused by the second spherical harmonic in cosmic ray distribution was found and it has the amplitude 0.020 plus or minus 0.002%. The sidereal anisotropy with a very small amplitude (not more than 0.005%) was observed to exist

Elasticity-mediated self-organization and colloidal interactions of solid spheres with tangential anchoring in a nematic liquid crystal

Using laser tweezers and fluorescence confocal polarizing microscopy, we study colloidal interactions of solid microspheres in the nematic bulk caused by elastic distortions around the particles with strong tangential surface anchoring. The particles aggregate into chains directed at about 30 degrees to the far field director and, at higher concentrations, form complex kinetically trapped structures. We characterize the distance and angular dependencies of the colloidal interaction forces.Comment: 6 pages, 5 figure

Change of cosmic ray anisotropy with solar activity

Muon telescope data at various depths underground in Yakutsk within energy range 10 to 300 GeV for 1957 to 1984 are analyzed. The 22-year variation of the interplanetary magnetic field aligned component is found. The variation is caused by interaction of heliomagnetosphere with the local galactic field and interstellar wind

Sensitivity of depth of maximum and absorption depth of EAS to hadron production mechanism

Comparison of experimental data on depth of extensive air showers (EAS) development maximum in the atmosphere, T sub M and path of absorption, lambda, in the lower atmosphere of EAS with fixed particle number in the energy region eV with the results of calculation show that these parameters are sensitive mainly to the inelastic interaction cross section and scaling violation in the fragmentation and pionization region. The data are explained in a unified manner within the framework of a model in which scaling is violated slightly in the fragmentation region and strongly in the pionization region at primary cosmic rays composition close to the normal one and a permanent increase of inelastic interaction cross section. It is shown that, while interpreting the experimental data, disregard of two methodical points causes a systematic shift in T sub M: (1) shower selection system; and (2) EAS electron lateral distribution when performing the calculations on basis of which the transfer is made from the Cerenkov pulse FWHM to the depth of shower maximum, T sub M

DESERT: Decision Support System for Evaluating River Basin Strategies

An integrated PC-based software package for decision support in water quality management on a river basin scale has been developed. The software incorporates a number of useful tools, including an easy-to-use data handling module with a dBase style database engine, simulation and calibration of hydraulics and water quality, display of computed data with the help of external spreadsheet software, and optimization based on dynamic programming algorithm. The main utility of the package is to provide useful and powerful instrument for water quality assessment and decision making in emission control, including selection of wastewater treatment alternatives, standard setting and enforcement at the river basin level. Two versions of the decision support software are presented, the current version and development of a follow-up program with extended features

CARS polarized microscopy of three-dimensional director structures in liquid crystals

We demonstrate three-dimensional vibrational imaging of director structures in liquid crystals using coherent anti-Stokes Raman scattering (CARS) polarized microscopy. Spatial mapping of the structures is based on sensitivity of a polarized CARS signal to orientation of anisotropic molecules in liquid crystals. As an example, we study structures in a smectic material and demonstrate that single-scan CARS and two-photon fluorescence images of molecular orientation patterns are consistent with each other and with the structure model.Comment: 5 pages, 4 figures, published in Appl.

Towards single-electron metrology

We review the status of the understanding of single-electron transport (SET) devices with respect to their applicability in metrology. Their envisioned role as the basis of a high-precision electrical standard is outlined and is discussed in the context of other standards. The operation principles of single electron transistors, turnstiles and pumps are explained and the fundamental limits of these devices are discussed in detail. We describe the various physical mechanisms that influence the device uncertainty and review the analytical and numerical methods needed to calculate the intrinsic uncertainty and to optimise the fabrication and operation parameters. Recent experimental results are evaluated and compared with theoretical predictions. Although there are discrepancies between theory and experiments, the intrinsic uncertainty is already small enough to start preparing for the first SET-based metrological applications.Comment: 39 pages, 14 figures.

The activity of copper-containing enzymes in the birch leaves in the conditions of the built environment

© 2016, International Journal of Pharmacy and Technology. All rights reserved.In work dynamics of cupriferous enzymes in leaves of silver birch which is constant object of green construction in the anthropogenous environment is shown. Many researches indicate interrelation of adaptive opportunities of a vegetable organism and functioning of enzymatic system, including cupriferous enzymes of a poliphenoloxidaza and ascorbinatoxidaza. Activity of an ascorbinatoxidaza was determined by a method which is based on property of ascorbic acid to absorb light with a maximum at the wavelength of 265 nanometers. About activity of enzyme judged by reduction of size of optical density, considering that the oxidation level of ascorbic acid is proportional to amount of enzyme. Activity of a poliphenoloxidaza was determined by spectrotometric method which is based on measurement of optical density of products of reaction which are formed at oxidation of pyrocatechin for a certain period. During all vegetative period, plants in the conditions of the urban environment, had an increase in activity of a poliphenoloxidaza with achievement of the maximum value in August. In both years of observations (2014 and 2015) there was a decrease of the activity of an ascorbinatoxidaza in leaves during active vegetation of plants, and in the native habitat, on the contrary, its increase. The minimum values of activity of this enzyme are noted in August in the near-road plantings

АНАЛІЗ РЕЗУЛЬТАТІВ ФІНАНСОВО-ГОСПОДАРСЬКОЇ ДІЯЛЬНОСТІ СУБЄКТІВ ГОСПОДАРЮВАННЯ В УМОВАХ СТАЛОГО РОЗВИТКУ

Every year the number of users interested in non-financial reporting grows. Their aim is to assess company activity including not only their financial performance but also their contribution to social and economic development of society. However, non-financial reporting cannot provide full information to users in order to satisfy all their requirements. It is upon Integrated Reporting (IR), which refers to financial and non-financial indexes. In the article disclosure the analysis of financial and business performance technique for national entities (private as well as public sectors of economy) that would include using financial and non-financial indexes.To standardize financial and operating performance indexes, their possible comparison, macro and micro modeling, it is proposed to identify Index of performance, which is defined by the system of complex indexes: index (indicator) of reaching business entity economic indicators, index (indicator) for ecological efficiency, index (indicator) for social efficiency. It was grounded the necessity to calculate Quality coefficient assessment to avoid declarative achievement of ecological and social efficiency indexes, the quality of their performance.Исследованы масштабы и перспективы внедрения нефинансовой отчетности в современных условиях социально-экономического развития.
