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

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

Cyber sales as the latest tool for optimizing an enterprise strategy

Cyber sales as the latest tool for optimizing an enterprise strategy / Yu. Robul, O. Deineha, M. Prokopenko, N. Novikova, O. Lukianykhina, N. Baistriuchenko // International journal of scientific & technology research. – 2020. – Vol. 9, Issue 02 ( February ). – P 5264-5268.Ця стаття допоможе оптимізувати цифрову стратегію підприємства, перейшовши від холодних продажів із втратою до 99% трафіку до автоматичних продажів за допомогою чат-ботів і найвищої конверсії.An independent and informed buyer, for the most part, no longer responds to attempts to sell him something ―on the forehead. The paradigm of ―cold sales and the constant search for new customers does not compete with the new strategy - building long-term relationships with customers using specially designed ―sales tunnels. The article reveals the concept of cyber-sales or auto-funnels. The methodology of construction and operation of automatic sales tunnels is shown, both at the preparation and planning stage and at the stage of technical implementation of the sales tunnel. Particular attention in the article is given to chatbots, which are used in instant messengers for the technical organization of sales tunnels. They can build communication with the client around the clock, perform tasks of information and promotion. They significantly reduce the cost and simplify work with clients. Every year, bots are becoming smarter and more functional. The article considers five main proposals that are necessary for the consumer to move through the funnel: Lead Magnet, Tripwire, Core Product, Profit Maximizer and Recurring Payments. The article also lists the main tools used in the planning, implementation and analysis of auto-funnels. Cyber sales in business is a customer communication system that works automatically. A sequential chain of interconnected content that, like a tunnel, leads a customer to a purchase. In fact, this automated system is an alternative to the services of a sales manager. This article will help optimize the digital strategy of the enterprise by moving from cold sales with a loss of up to 99% of traffic to automatic sales using chatbots and the highest conversion.Эта статья поможет оптимизировать цифровую стратегию предприятия, перейдя от холодных продаж с потерей до 99% трафика к автоматическим продажам с использованием чат-ботов и максимальной конверсией

Measurement of the semileptonic charge asymmetry in B0 meson mixing with the D0 detector

We present a measurement of the semileptonic mixing asymmetry for B0 mesons, a^d_{sl}, using two independent decay channels: B0 -> mu+D-X, with D- -> K+pi-pi-; and B0 -> mu+D*-X, with D*- -> antiD0 pi-, antiD0 -> K+pi- (and charge conjugate processes). We use a data sample corresponding to 10.4 fb^{-1} of ppbar collisions at sqrt(s) = 1.96 TeV, collected with the D0 experiment at the Fermilab Tevatron collider. We extract the charge asymmetries in these two channels as a function of the visible proper decay length (VPDL) of the B0 meson, correct for detector-related asymmetries using data-driven methods, and account for dilution from charge-symmetric processes using Monte Carlo simulation. The final measurement combines four signal VPDL regions for each channel, yielding a^d_{sl} = [0.68 \pm 0.45 \text{(stat.)} \pm 0.14 \text{(syst.)}]%. This is the single most precise measurement of this parameter, with uncertainties smaller than the current world average of B factory measurements.Comment: Version includes minor textual changes following peer review by journal, most notably the updating of Ref.
