On elliptic solutions of the quintic complex one-dimensional Ginzburg-Landau equation
The Conte-Musette method has been modified for the search of only elliptic
solutions to systems of differential equations. A key idea of this a priory
restriction is to simplify calculations by means of the use of a few Laurent
series solutions instead of one and the use of the residue theorem. The
application of our approach to the quintic complex one-dimensional
Ginzburg-Landau equation (CGLE5) allows to find elliptic solutions in the wave
form. We also find restrictions on coefficients, which are necessary conditions
for the existence of elliptic solutions for the CGLE5. Using the investigation
of the CGLE5 as an example, we demonstrate that to find elliptic solutions the
analysis of a system of differential equations is more preferable than the
analysis of the equivalent single differential equation.Comment: LaTeX, 21 page
Report of the QCD Tools Working Group
We report on the activities of the ``QCD Tools for heavy flavors and new
physics searches'' working group of the Run II Workshop on QCD and Weak Bosons.
The contributions cover the topics of improved parton showering and comparisons
of Monte Carlo programs and resummation calculations, recent developments in
Pythia, the methodology of measuring backgrounds to new physics searches,
variable flavor number schemes for heavy quark electro-production, the
underlying event in hard scattering processes, and the Monte Carlo MCFM for NLO
processes.Comment: LaTeX, 47 pages, 41 figures, 10 tables, uses run2col.sty, to appear

Электрохимическое обезмеживание медно-сульфатного электролита
Copper and nickel ions are accumulated in the solution during electrolytic refining of copper. These ions need to be extracted from the solution from time to time. In industry copper extraction is carried out in two stages. It results in copper ions concentration reducing to 1 g/l. Numerical simulation was used to define dependence of the process of copper extraction from particular parameters: mixing of electrolyte, volume of electrolyte, area of cathodic surface. The process of copper extraction was investigated in still electrolyte and during mixing of the solution. Smooth and compact precipitate crystallized on the cathode in all experiments. Rate of copper extraction during mixing of electrolyte is higher than in still electrolyte. The industrial method of abuseive sulphate electrolyte results in the formation on the cathode dendritic sediment copper ions which are restored in extreme conditions. The decrease in the concentration of copper at I = const causes the formation of dendritic sludge that is easily crumbles to the bottom of the cell, enriching copper sludge. Guarantee smooth sediment when basmajian with obtaining compact copper, excluding besides the recovery of arsenic emitting poisonous arsina cars is the organization of intensive mixing or electrolyte circulation, ensuring the recovery of copper ions in limitless conditions smooth and sediment.При электролитическом рафинировании меди в растворе электролита накапливаются ионы никеля и меди, которые необходимо периодически извлекать. В промышленности извлечение меди проводят в две стадии, снижая концентрацию меди до 1 г/л. Численным моделированием установлена зависимость скорости обезмеживания от отдельных параметров: перемешивания электролита, его объема, площади катодной поверхности,. Экспериментально исследован процесс обезмеживания в спокойном электролите и при перемешивании раствора. Во всех опытах на катоде кристаллизовался гладкий, компактный осадок меди. Скорость обезмеживания при организации принудительного перемешивания выше, чем в спокойном электролите
Charm-sea Contribution to High-p_T \psi Production at the Fermilab Tevatron
The direct production of at large transverse momentum, , at the Fermilab Tevatron is revisited. It is found that the
sea-quark initiated processes dominate in the high- region within the
framework of color-singlet model, which is not widely realized. We think this
finding is enlightening for further investigation on the charmonium production
mechanism.Comment: Conclusions not changed, to appear in J. of Phys.
Parton Distributions Working Group
The main focus of this working group was to investigate the different issues
associated with the development of quantitative tools to estimate parton
distribution functions uncertainties. In the conclusion, we introduce a
"Manifesto" that describes an optimal method for reporting data.Comment: Report of the Parton Distributions Working Group of the 'QCD and Weak

Morbidity Rates of Q Fever in the Russian Federation and European Countries: Realities and Problems
Q fever poses a problem, both in the Russian Federation and abroad. Thereat, a new base normative document, sanitary-epidemiological regulations on coxiellosis prevention, has been developed and approved in the Russian Federation. For the first time ever in the world history, a regulated surveillance of community-acquired pneumonias, which will help to improve diagnostics of this pathology, has been introduced in our country. Quality of Q fever control directly depends on the laboratory facilities, qualification of the personnel, and coordination of interagency cooperation. All these factors provide for the prompt assessment of the situation, in-time anti-epidemic measures, and forecasting of the events, which ensures the biological security of Russian Federation
Dense Plasma Focus: physics and applications (radiation material science, single-shot disclosure of hidden illegal objects, radiation biology and medicine, etc.)
The paper presents some outcomes obtained during the year of 2013 of the activity in the frame of the International Atomic Energy Agency Co-ordinated research project "Investigations of Materials under High Repetition and Intense Fusion-Relevant Pulses". The main results are related to the effects created at the interaction of powerful pulses of different types of radiation (soft and hard X-rays, hot plasma and fast ion streams, neutrons, etc. generated in Dense Plasma Focus (DPF) facilities) with various materials including those that are counted as perspective ones for their use in future thermonuclear reactors. Besides we discuss phenomena observed at the irradiation of biological test objects. We examine possible applications of nanosecond powerful pulses of neutrons to the aims of nuclear medicine and for disclosure of hidden illegal objects. Special attention is devoted to discussions of a possibility to create extremely large and enormously diminutive DPF devices and probabilities of their use in energetics, medicine and modern electronics
