ПРОБЛЕМЫ РАЗВИТИЯ РОССИЙСКОЙ КООПЕРАЦИИ НА СЕЛЕ И ПРЕДЛОЖЕНИЯ ПО ИХ РЕШЕНИЮ

The article analyzes the main positive features characterizing agricultural consumer cooperation. The paper reveals factors preventing agricultural cooperatives working in Russia. The author defines the key goal of agricultural cooperatives’ state support as improvement of rural population quality of life. It should provide rural people with own-produced food stuff, increase rural people employment and earnings, make national agricultural producers being the main suppliers of competitive food production to regional, national and world market. The publication demonstrates that weak legislation regulating agricultural cooperation in the country increases legal, organizational and financial risks of cooperatives. The author observes lack of capacities and wish in cooperatives to look for own resources aimed at their development (capital strengthening, increase in reserve, building protection and security elements, building by means of guarantee and insurance funds). The paper shows contradictions between participants of agricultural cooperatives and partners at all the stages of activity. All mentioned above performs as a negative factor in cooperation being voluntary and popular. The author suggests an activity plan “road map” aimed at building institutional environment of agricultural cooperation in rural areas. The development directions include strengthening of legislation; building the system of state regulation and support; scientific, information and consulting support and infrastructure development.На основе проведенного анализа определены основные положительные черты, характеризующие сельскохозяйственную потребительскую кооперацию. Выявлены факторы, сдерживающие развитие сельскохозяйственных кооперативов в России. Обозначена ключевая цель государственной поддержки сельскохозяйственной кооперации: это повышение качества жизни сельского населения до уровня, позволяющего не только полностью обеспечить сельское население продовольствием собственного производства, повысить его занятость и доходы, но и превратить отечественных сельскохозяйственных товаропроизводителей в  главных поставщиков конкурентного продовольствия на региональные, национальные и мировые рынки. Установлено, что несовершенство законодательной и нормативной базы, определяющее деятельность сельскохозяйственной кооперации в стране, увеличивает правовые, организационные и финансовые риски кооперативов. Кооперативы не стремятся изыскивать собственные ресурсы для своего развития (наращивание собственного капитала, увеличение резервного фонда, формирование элементов защиты – ресурсов гарантийных и страховых фондов). Накапливаются противоречия между участниками работающих сельскохозяйственных кооперативов и  партнерами на всех этапах деятельности. Все это в  условиях отсутствия внятной кооперативной политики на селе служит дополнительным отталкивающим фактором в превращении кооперации в добровольное и массовое движение. На основе проведенного исследования разработан план действия «дорожная карта», целью которого является формирование институциональной среды сельскохозяйственной кооперации на селе, включающее совершенствование законодательства, формирование системы государственного регулирования и  поддержки, научного, информационного и консультационного обеспечения, развитие инфраструктуры

Growth of SiC films by the method of substitution of atoms on porous Si (100) and (111) substrates

The mechanisms of growth of silicon carbide (SiC) films by the method of substitution of atoms on macro- and mesoporous silicon substrates (Si) of p- and n-type conduction are investigated. Significant dependence of the rate and the mechanism of nucleation of SiC layers on Si on the type of Si doping and its crystallographic orientation is experimentally found. Comparison of the experimental data with the theoretical results obtained earlier is performed. It is shown that the presence of the system of pores on the surface allows one to significantly increase the thickness of silicon transformed into SiC during the process of synthesis by the method of substitution of atoms, which was equal to 115 microns in our experiments. The obtained samples are studied by methods of scanning electron microscopy, micro-Raman spectroscopy, and X-ray diffraction analysis. Numerical simulation of the distribution of elastic stresses caused by the difference in thermal expansion coefficients (TEC) in the heterostructures of GaN/SiC/porous Si/Si is conducted. It is revealed that the presence of pores in the near-surface layers of Si leads to considerable relaxation of elastic stresses in GaN films caused by differences in the TEC between GaN and Si

Alignment of the ALICE Inner Tracking System with cosmic-ray tracks

37 pages, 15 figures, revised version, accepted by JINSTALICE (A Large Ion Collider Experiment) is the LHC (Large Hadron Collider) experiment devoted to investigating the strongly interacting matter created in nucleus-nucleus collisions at the LHC energies. The ALICE ITS, Inner Tracking System, consists of six cylindrical layers of silicon detectors with three different technologies; in the outward direction: two layers of pixel detectors, two layers each of drift, and strip detectors. The number of parameters to be determined in the spatial alignment of the 2198 sensor modules of the ITS is about 13,000. The target alignment precision is well below 10 micron in some cases (pixels). The sources of alignment information include survey measurements, and the reconstructed tracks from cosmic rays and from proton-proton collisions. The main track-based alignment method uses the Millepede global approach. An iterative local method was developed and used as well. We present the results obtained for the ITS alignment using about 10^5 charged tracks from cosmic rays that have been collected during summer 2008, with the ALICE solenoidal magnet switched off.Peer reviewe

Transverse momentum spectra of charged particles in proton-proton collisions at s=900\sqrt{s} = 900 GeV with ALICE at the LHC

The inclusive charged particle transverse momentum distribution is measured in proton-proton collisions at $\sqrt{s} = 900$ GeV at the LHC using the ALICE detector. The measurement is performed in the central pseudorapidity region $(|\eta|<0.8)$ over the transverse momentum range $0.15<p_{\rm T}<10$ GeV/$c$. The correlation between transverse momentum and particle multiplicity is also studied. Results are presented for inelastic (INEL) and non-single-diffractive (NSD) events. The average transverse momentum for $|\eta|<0.8$ is $\left<p_{\rm T}\right>_{\rm INEL}=0.483\pm0.001$ (stat.) $\pm0.007$ (syst.) GeV/$c$ and \left_{\rm NSD}=0.489\pm0.001 (stat.) $\pm0.007$ (syst.) GeV/$c$, respectively. The data exhibit a slightly larger $\left<p_{\rm T}\right>$ than measurements in wider pseudorapidity intervals. The results are compared to simulations with the Monte Carlo event generators PYTHIA and PHOJET.Comment: 20 pages, 8 figures, 2 tables, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/390

HE-LHC: The High-Energy Large Hadron Collider – Future Circular Collider Conceptual Design Report Volume 4

In response to the 2013 Update of the European Strategy for Particle Physics (EPPSU), the Future Circular Collider (FCC) study was launched as a world-wide international collaboration hosted by CERN. The FCC study covered an energy-frontier hadron collider (FCC-hh), a highest-luminosity high-energy lepton collider (FCC-ee), the corresponding 100 km tunnel infrastructure, as well as the physics opportunities of these two colliders, and a high-energy LHC, based on FCC-hh technology. This document constitutes the third volume of the FCC Conceptual Design Report, devoted to the hadron collider FCC-hh. It summarizes the FCC-hh physics discovery opportunities, presents the FCC-hh accelerator design, performance reach, and staged operation plan, discusses the underlying technologies, the civil engineering and technical infrastructure, and also sketches a possible implementation. Combining ingredients from the Large Hadron Collider (LHC), the high-luminosity LHC upgrade and adding novel technologies and approaches, the FCC-hh design aims at significantly extending the energy frontier to 100 TeV. Its unprecedented centre-of-mass collision energy will make the FCC-hh a unique instrument to explore physics beyond the Standard Model, offering great direct sensitivity to new physics and discoveries

FCC-ee: The Lepton Collider: Future Circular Collider Conceptual Design Report Volume 2

In response to the 2013 Update of the European Strategy for Particle Physics, the Future Circular Collider (FCC) study was launched, as an international collaboration hosted by CERN. This study covers a highest-luminosity high-energy lepton collider (FCC-ee) and an energy-frontier hadron collider (FCC-hh), which could, successively, be installed in the same 100 km tunnel. The scientific capabilities of the integrated FCC programme would serve the worldwide community throughout the 21st century. The FCC study also investigates an LHC energy upgrade, using FCC-hh technology. This document constitutes the second volume of the FCC Conceptual Design Report, devoted to the electron-positron collider FCC-ee. After summarizing the physics discovery opportunities, it presents the accelerator design, performance reach, a staged operation scenario, the underlying technologies, civil engineering, technical infrastructure, and an implementation plan. FCC-ee can be built with today’s technology. Most of the FCC-ee infrastructure could be reused for FCC-hh. Combining concepts from past and present lepton colliders and adding a few novel elements, the FCC-ee design promises outstandingly high luminosity. This will make the FCC-ee a unique precision instrument to study the heaviest known particles (Z, W and H bosons and the top quark), offering great direct and indirect sensitivity to new physics
