Environmental Improvement Of Opencast Mining

Existing classifications of waste dumps in the quarries are given and their phenomenological nature is clarified. The need to identify the essence of the term "dump" is shown as well as the idea of "dump" as an artificial formation with everted and mixed rocks distanced from the quarry. Essential classification of man-made rock formations in quarries is developed. Characteristic of variations of man-made waste formations in quarries is developed. To reduce harmful effects of open-pit mining, dumps should be substituted with strat-lays - man-made structures relevant to natural stratification of litho-substances. Construction of strat-lays would improve ecological and technological culture of open cast mining

Modeling of Regional Development Using a Structural Approach: Principles, Tools and Experience of Their Application

To solve the priority task of the Russian Federation to ensure the effective socio-economic and sustainable development of the regions, it is necessary to carry out an adequate structural policy, the main purpose of which is to form a rational and balanced structure of the economy that can ensure the effective development of the region’s economy. In this regard, the relevance of modeling regional development using a structural approach is beyond doubt. The purpose of the research is to substantiate the need for a close study of the specifics of the regional structure and the features of its modeling, taking into account General and specific principles, tools and practical experience of their application. Scientific novelty is the study of not only the basic laws, features, principles, tools for modeling the structure of the region, but also the experience of their application in determining the proportions and trends in the development of the region in order to conduct an adequate structural policy. The study used theoretical and empirical methods, in particular: literature review, logical and system analysis, methods of empirical data collection, description, modeling, forecasting and processing of research results. As a result of the study, the authors obtained the following results: a comparative analysis of approaches to the definition of the concept of “region”, “structure of the region”; justified that the structure gives the necessary integrity and defines the main characteristics of the region, allowing to consider it as a complete socio-economic system; classification of types of regional structures; justified that the main quality property of the territory is polystructural. As a conclusion, the authors note that in this regard, there can be no single approach to the description of the structure for modeling regional development. Approbation of the author’s approaches to the structuring of the regional economy is made on the materials of the Kursk region. It showed the adequacy of the developed theoretical provisions and allowed to determine the directions of their further development for the improvement of regional structural policy

Complications of the recovery period after arthroscopic reconstruction of the anterior cruciate ligament

A review of the literature is devoted to the problem of complications after arthroscopic reconstruction of the anterior cruciate ligament. The authors covered questions of epidemiology and surgical technique, touched on important aspects of the main complications, such as graft damage, arthrofibrosis and impingement syndrome, the formation of synovial cysts, infections, the development of osteoarthritis and cartilage degeneration. Despite the prevalence of pathology, a huge number of publications and the development of arthroscopic surgery, there are many theoretical and technical problems, that have not yet found a satisfactory solution and require further development. A relevant question for the doctor is the problem of correctly choosing the method or combination methods for anterior cruciate ligament reconstruction in relation for each patient, considering the individual characteristics and possible risks of developing different complications in patient

Relative luminosity measurement of the LHC with the ATLAS forward calorimeter

In this paper it is shown that a measurement of the relative luminosity changes at the LHC may be obtained by analysing the currents drawn from the high voltage power supplies of the electromagnetic section of the forward calorimeter of the ATLAS detector. The method was verified with a reproduction of a small section of the ATLAS forward calorimeter using proton beams of known beam energies and variable intensities at the U-70 accelerator at IHEP in Protvino, Russia. The experimental setup and the data taking during a test beam run in April 2008 are described in detail. A comparison of the measured high voltage currents with reference measurements from beam intensity monitors shows a linear dependence on the beam intensity. The non-linearities are measured to be less than 0.5 % combining statistical and systematic uncertainties.Comment: 16 page

Measurement of Leptonic Asymmetries and Top Quark Polarization in ttbar Production

We present measurements of lepton (l) angular distributions in ttbar -> W+ b W- b -> l+ nu b l- nubar bbar decays produced in ppbar collisions at a center-of-mass energy of sqrt(s)=1.96TeV, where l is an electron or muon. Using data corresponding to an integrated luminosity of 5.4fb^-1, collected with the D0 detector at the Fermilab Collider, we find that the angular distributions of l- relative to anti-protons and l+ relative to protons are in agreement with each other. Combining the two distributions and correcting for detector acceptance we obtain the forward-backward asymmetry A^l_FB = (5.8 +- 5.1(stat) +- 1.3(syst))%, compared to the standard model prediction of A^l_FB (predicted) = (4.7 +- 0.1)%. This result is further combined with the measurement based on the analysis of the l+jets final state to obtain A^l_FB = (11.8 +- 3.2)%. Furthermore, we present a first study of the top-quark polarization.Comment: submitted versio

We present the first measurements of the differential cross section d sigma/dp(T)(gamma) for the production of an isolated photon in association with at least two b-quark jets. The measurements consider photons with rapidities vertical bar y(gamma)vertical bar < 1.0 and transverse momenta 30 < p(T)(gamma) < 200 GeV. The b-quark jets are required to have p(T)(jet) > 15 GeVand vertical bar y(jet)vertical bar < 1.5. The ratio of differential production cross sections for gamma + 2 b-jets to gamma + b-jet as a function of p(T)(gamma) is also presented. The results are based on the proton-antiproton collision data at root s = 1.96 TeV collected with the D0 detector at the Fermilab Tevatron Collider. The measured cross sections and their ratios are compared to the next- to- leading order perturbative QCD calculations as well as predictions based on the k(T)- factorization approach and those from the sherpa and pythia Monte Carlo event generators

Precise measurement of the top quark mass in the dilepton channel at D0

We measure the top quark mass (mt) in ppbar collisions at a center of mass energy of 1.96 TeV using dilepton ttbar->W+bW-bbar->l+nubl-nubarbbar events, where l denotes an electron, a muon, or a tau that decays leptonically. The data correspond to an integrated luminosity of 5.4 fb-1 collected with the D0 detector at the Fermilab Tevatron Collider. We obtain mt = 174.0 +- 1.8(stat) +- 2.4(syst) GeV, which is in agreement with the current world average mt = 173.3 +- 1.1 GeV. This is currently the most precise measurement of mt in the dilepton channel.Comment: 7 pages, 4 figure
