Recent atmospheric neutrino results from Soudan 2

An updated measurement of the atmospheric nu_mu/nu_e ratio-of-ratios, 0.68+-0.11+-0.06, has been obtained using a 4.6-kty exposure of the Soudan-2 iron tracking calorimeter. The L/E distributions have been analyzed for effects of nu_mu -> nu_x oscillations, and an allowed region in the Delta m^2 vs. sin^2 2 theta plane has been determined.Comment: 3 pages, 4 figures; presented at TAUP99, the 6th Int.

Mixed convection in a rotating porous cavity having local heater

Numerical simulation of convective heat transfer inside a rotating porous square cavity with local heater of constant temperature has been performed. Governing equations formulated on the basis of mass, momentum and energy conservation laws written using the dimensionless stream function, vorticity and temperature have been solved by the finite difference method. The effects of Rayleigh and Taylor numbers on periodic flow and heat transfer have been studied

Analysis of Control Measures for Vector-borne Diseases Using a Multistage Vector Model with Multi-Host Sub-populations

We propose and analyze an epidemiological model for vector borne diseases that integrates a multi-stage vector population and several host sub-populations which may be characterized by a variety of compartmental model types: subpopulations all include Susceptible and Infected compartments, but may or may not include Exposed and/or Recovered compartments. The model was originally designed to evaluate the effectiveness of various prophylactic measures in malaria-endemic areas, but can be applied as well to other vector-borne diseases. This model is expressed as a system of several differential equations, where the number of equations depends on the particular assumptions of the model. We compute the basic reproduction number $\mathcal R_0$, and show that if $\mathcal R_0\leqslant 1$, the disease free equilibrium (DFE) is globally asymptotically stable (GAS) on the nonnegative orthant. If $\mathcal R_0>1$, the system admits a unique endemic equilibrium (EE) that is GAS. We analyze the sensitivity of $R_0$ and the EE to different system parameters, and based on this analysis we discuss the relative effectiveness of different control measures.Comment: 42 pages, 3 figures. arXiv admin note: substantial text overlap with arXiv:1808.0757

Photocatalytic degradation of diclofenac in wastewater using ironceramic composites

The photocatalytic degradation of diclofenac in model aqueous solution is investigated. The surface of composites were correlated with photocatalytic activity. Adsorption activity of the composites is related to the presence of surface active sites. The degradation under UV irradiation and photo-Fenton process using ironceramic composites is more effective than direct photolysis

The Kentucky Noisy Monte Carlo Algorithm for Wilson Dynamical Fermions

We develop an implementation for a recently proposed Noisy Monte Carlo approach to the simulation of lattice QCD with dynamical fermions by incorporating the full fermion determinant directly. Our algorithm uses a quenched gauge field update with a shifted gauge coupling to minimize fluctuations in the trace log of the Wilson Dirac matrix. The details of tuning the gauge coupling shift as well as results for the distribution of noisy estimators in our implementation are given. We present data for some basic observables from the noisy method, as well as acceptance rate information and discuss potential autocorrelation and sign violation effects. Both the results and the efficiency of the algorithm are compared against those of Hybrid Monte Carlo.

Оценка эффективности использования основных фондов нефтегазового предприятия (на примере ОАО «Стройтрансгаз Сибирь»)

Целью дипломной работы является анализ основных фондов и оценка эффективности их использования, а также разработка эффективных путей и инструментов управления основными средствами на предприятии. Объектом исследования послужило открытое акционерное общество «Стройтрансгаз Сибирь», осуществляющее свою деятельность на территории Томской области. Период исследования составил три года (2013-2015 гг.). В финансово-хозяйственной деятельности организации основные средства занимают одно из центральных мест. Эффективное их использование способствует оптимальному и экономному потреблению других видов ресурсов (например, сырья, материалов и т.д.). Таким образом, от состояния и эффективного использования основных средств зависят и качественные показатели деятельности хозяйствующего субъекта. Основными показателями, характеризующими эффективность использования основных средств, являются: фондоотдача, фондоемкость и фондорентабельность. Немаловажное значение имеют и коэффициенты технического состояния основных средств (коэффициенты годности, износа). В качестве конкретного мероприятия по повышению эффективности использования основных средств ОАО «Стройтрансгаз Сибирь» было предложено использовать специальный корректировочный коэффициент с целью сближения фактического физического состояния основных фондов и их бухгалтерского отражения.The aim of the thesis is the analysis of the fixed assets and estimation of efficiency of their use and the development of effective ways and tools of asset management at the enterprise. The object of the study served as an open joint stock company "Stroytransgaz Siberia" carries out its activity on the territory of Tomsk region. The study period was three years (2013-2015). In the financial-economic activity of the organization major means is one of the Central places. Their effective use promotes optimal and economical consumption of other types of resources (e.g., raw materials, etc.). Thus, the condition and effective use of fixed assets depend on the quality of the activities of the entity. The main indicators characterizing the efficiency of use of fixed assets are capital productivity, capital intensity and fondamentalisti. Also important, the coefficients of technical condition of fixed assets (coefficients of shelf life wear). As specific measures to improve the efficiency of use of fixed assets of OJSC "Stroytransgaz Siberia" it was proposed to use a special deemphasize the gaps between the actual physical condition of fixed assets and their accounting treatment

Search for the Proton Decay Mode proton to neutrino K+ in Soudan 2

We have searched for the proton decay mode proton to neutrino K+ using the one-kiloton Soudan 2 high resolution calorimeter. Contained events obtained from a 3.56 kiloton-year fiducial exposure through June 1997 are examined for occurrence of a visible K+ track which decays at rest into mu+ nu or pi+ pi0. We found one candidate event consistent with background, yielding a limit, tau/B > 4.3 10^{31} years at 90% CL with no background subtraction.Comment: 13 pages, Latex, 3 tables and 3 figures, Accepted by Physics Letters

A Lattice Study of the Magnetic Moment and the Spin Structure of the Nucleon

Using an approach free from momentum extrapolation, we calculate the nucleon magnetic moment and the fraction of the nucleon spin carried by the quark angular momentum in the quenched lattice QCD approximation. Quarks with three values of lattice masses, 210, 124 and 80 MeV, are formulated on the lattice using the standard Wilson approach. At every mass, 100 gluon configurations on 16^3 x 32 lattice with \beta=6.0 are used for statistical averaging. The results are compared with the previous calculations with momentum extrapolation. The contribution of the disconnected diagrams is studied at the largest quark mass using noise theory technique.Comment: 14 pages, 3 figures, Talk given at Lattice2001, Berlin, German
