DIGITAL GOVERNMENT: DYNAMICS OF INTERACTION BETWEEN STATE AND RUSSIAN SOCIETY IN THE HEAT OF COVID-19
No full textIn the 21st century, one of the dominants of the modern stage of development of states is the elevation of the role of information and communication technologies ( the ICT), which, in turn, are actively implemented and used in the public administration system, creating new effective means of interaction between government bodies, citizens and various commercial structures. A striking example of the interaction between states and people is electronic government (E-government). Digital maturity is a key indicator of the readiness of the state and companies to implement digital solutions in their processes. At the same time, the coronavirus pandemic has already forced large companies to reconsider their strategies in favor of investments in digital technologies
Parasitosis of Ruminant Animal in Private Farms of Vysokogorny and Laishevskiy Districts of the Republic of Tatarstan
No full textThe purpose of the research is to study the species composition of intestinal parasitosis agents in ruminant animals in citizens’ private farms in Vysokogorny and Laishevskiy districts of the Republic of Tatarstan. Materials and methods. The work has been executed in the Epizootology, Parasitology and Radiobiology Department at the Kazan State Academy of Veterinary Science named after N.E.Bauman and in citizens’ private farms in Vysokogorny and Laishevskiy districts of the Republic of Tatarstan during autumn-winter period in 2016-2017. 586 fecal specimen, including 364 samples of cattle, 168 samples of sheep and 54 samples of goats, have been studied by the modified method of flotation. Animals extent of invasion were determined as well as average number of helminth eggs and eimeria oocyst in 1 g of feces were calculated with the help of VIGIS count chamber. Kheisin key was used to identify eimeria types. Statistical analysis of numeric material was carried out with the help of Microsoft Excel spreadsheet processor. Results and discussion. Eggs of helminth classes Fasciola, Moniezia, Nematodirus, Trichocephalus as well as eimeria oocyst had been founded in cattle and small ruminants fecal specimen. On investigated areas the degree of infection by fascioles was 28.2%, by moniezia 41.5%, by nematodirus 52.7%, by trichocephalus 28.3%, and by eimeria 51.3%. Small ruminants were infected with fascioles in 56.5%, moniezia in 52.7%, thysaniezia in 15.7%, nematodirus in 58.1%, trichocephalus in 38.5%, and eimeria in 21.3%. Taking into consideration prevalence of parasitosis of ruminant animal in private farms of Vysokogorny and Laishevskiy districts of the Republic of Tatarstan it is necessary to make up a plan of antiparasitic measures inclusive of climate pattern and developmental biology of agents
The ALICE CPV Detector
No full textThe Charged-Particle Veto (CPV) detector of ALICE at the LHC is presented. Physics motivation for the detector, its construction and operation in physics runs are shortly discussed. Readout electronics and data taking conditions are described. Special attention is focused on CPV automation via the detector control system. Different states of the detector and protection algorithms implemented into the control system are described
Measuring (KSK +/-)-K-0 interactions using Pb-Pb collisions at root S-NN=2.76 TeV
No full textWe present the first ever measurements of femtoscopic correlations between the K-S(0) and K-+/- particles. The analysis was performed on the data from Pb-Pb collisions at root S-NN = 2.76 TeV measured by the ALICE experiment. The observed femtoscopic correlations are consistent with final-state interactions proceeding via the a(0)(980) resonance. The extracted kaon source radius and correlation strength parameters for (KSK-)-K-0 are found to be equal within the experimental uncertainties to those for (KSK+)-K-0. Comparing the results of the present study with those from published identical-kaon femtoscopic studies by ALICE, mass and coupling parameters for the a(0) resonance are tested. Our results are also compatible with the interpretation of the a(0) having a tetraquark structure instead of that of a diquark. (c) 2017 The Author. Published by Elsevier B.V

The measured correlation function is compared with the prediction obtained assuming only an attractive Coulomb interaction and a standard deviation in the range [3.6, 5.3] is found. Since the measured p-Ξ− ⊕ p ̄-Ξ ̄þ correlation is significantly enhanced with respect to the Coulomb prediction, the presence of an additional, strong, attractive interaction is evident. The data are compatible with recent lattice calculations by the HAL-QCD Collaboration, with a standard deviation in the range [1.8, 3.7]. The lattice potential predicts a shallow repulsive Ξ− interaction within pure neutron matter and this implies stiffer equations of state for neutron-rich matter including hyperons. Implications of the strong interaction for the modeling of neutron stars are discussed
Measurement of the production of high-p(T) electrons from heavy-flavour hadron decays in Pb-Pb collisions at root s(NN)=2.76 TeV
No full textElectrons from heavy-flavour hadron decays (charm and beauty) were measured with the ALICE detector in Pb-Pb collisions at a centre-of-mass of energy root s(NN) = 2.76 TeV. The transverse momentum (pT) differential production yields at mid-rapidity were used to calculate the nuclear modification factor R-AA in the interval 3 < p(T) < 18 GeV/c. The R-AA shows a strong suppression compared to binary scaling of pp collisions at the same energy (up to a factor of 4) in the 10% most central Pb-Pb collisions. There is a centrality trend of suppression, and a weaker suppression (down to a factor of 2) in semi-peripheral (50-80%) collisions is observed. The suppression of electrons in this broad p(T) interval indicates that both charm and beauty quarks lose energy when they traverse the hot medium formed in Pb-Pb collisions at LHC.

No full textInvestigating correlated fluctuations of conserved charges with net-A fluctuations in Pb-Pb collisions at ALICE
No full textEvent-by-event fluctuations of conserved charges such as electric
charge, strangeness, and baryon number - in ultrarelativistic heavy-ion
collisions provide insight into the properties of the quark-gluon plasma
and the QCD phase diagram. They can be related to the higher moments of
the multiplicity distributions of identified particles, such as the A
baryon which carries both strangeness and baryon number and is thus of
particular interest. We present the first measurement of net-A
fluctuations in Pb-Pb collisions at root s(NN)=5.02 TeV as a function of
centrality and the pseudorapidity acceptance of the measurement. The
results are compared to expectations of the effects of global baryon
number conservation as well as to predictions from the HIJING Monte
Carlo event generator. In this analysis the Identity Method is applied
in a novel way to account for the combinatoric background in the
invariant mass distribution
