Improving the quality management system of goods and services based on the Blockchain concept implementation and quality assessment in the digital economy
Authors: Yakovlev Andrey , Chernikova Anna , Livintsova Maria , Lebedeva Tatiana
Published: December 2019

When studying the development of the modern consumer market in Russia, a large number of low-quality goods and services remains constant. All this is fixed, despite the significant amount of domestic and international standards of the market system of accreditation and certification of the production processes of goods and services that are used in our country. It casts doubt on the feasibility of using quality management systems in Russia based on ISO 9000 due to their low efficiency. This requires the creation of a more advanced quality management system and the introduction into everyday practice of an effective mechanism that excludes the possibility of low-quality goods and services appearing on the markets. Based on systematic analysis of the reviewed literature the paper shows that organizations are not interested in providing consumer goods with the required quality, and the costumer himself cannot get an objective view of the real quality of the goods or services offered to him. The paper shows the need to create equal information conditions for all market participants from producer to consumer to optimize quality management systems. In conditions of the transition to digital economy concepts, the economic practice proves the effectiveness of the “Distributed registry” technology application. The possibility of falsifying information is extremely difficult. It is the basis for solving the problem of reducing transaction costs and, as a consequence, the management mechanism formation within the quality management systems.

Published: December 2019

The purpose of the article is to develop a model for interaction between industry higher educational institutions and the customer of educational services in order to increase the human potential in the industry. The article deals with the specifics of relations between the transport higher educational institutions and the company. To assess the quality of relations, the resource exchange model is suggested for use. The article formulates principles of interaction between the parties and indicators that can be used to assess the quality of the resources exchange. A model for interaction between the company’s bus iness units and higher educational institutions was proposed. The relations between the horizontal-structured corporation and educational institutions were modeled; the mathematical apparatus was selected to describe the contacts, indicators of satisfaction with the resources and the resultant indicator (satisfaction with the interaction) were proposed. The model will help to determine quantitative characteristics of the achieved contacts. Their introduction will make it possible to assess the original state of the contacts and proceed to functional design. Introduction of the concept of satisfaction with the resources and interaction in its individual lines will allow identifying the reserves to build on in order to optimize the contacts. The purpose of the modeling is to expand contacts between the higher educational institution and enterprises in the industry, to involve employees in innovation activities, to improve skills of the higher educational institution graduates in response to the needs of the industry. This article only looks at the interaction between industry higher educational institutions and business units of RZD OJSC, whereas recent years brought contacts between the university and many transport organizations that have specifics of market interactions described in the stakeholder theory.

Published: December 2019

The article discusses the impact of digital marketing on modern entrepreneurship, as well as the main tasks in the formation of the business structure. Predictions of rising consumer power in the digital age leading up to the turn of the century were bolstered by the advent of the Internet and then reignited by social media. Changes in consumer behavior require firms to rethink their marketing strategies in the digital sphere. Currently, much of the related research focuses more on the client than the firm. This study uses the firm’s perspective to facilitate understanding of digital marketing and the use of social media, as well as its benefits and inhibitors. The second generation of Internet applications enhances marketing efforts by allowing firms to introduce innovative forms of communication and co-create content with their customers. Firms ’ participation in digital marketing can be classified according to the perceived benefits and uses of digital marketing. To improve engagement with digital marketing, marketers need to focus on relationship-based interactions with their customers. This article demonstrates how some firms are already achieving just that.

Authors: Bespalov Vadim , Kushnarenko Tatyana , Paramonova Oksana
Published: December 2019

In the way of thinking of a modern man we are seeing a paradigm shift, namely, there is a gradual shift in priorities: ecological ones become primary, and economic – ones secondary. Progressive mankind more often pays attention to the preservation of natural resources, to environment purity, thereby trying to find the optimal ratio in solving environmental and economic issues. Analyzing the modern development of the sectors of the world national economy, we observe the prolonged dominance of economic priorities over environmental ones, which, in turn, cannot but negatively affect the state of the flora and fauna of our planet. These circumstances create, strange as it may seem, positive conditions for accelerating the creation of economic mechanisms for environmental protection aimed at reducing the anthropogenic impact of various factors on the environment. The economic efficiency of this activity is expressed through the prevented damage from environmental pollution. Construction is a branch of national economy which is always associated with interference in the environment; therefore, assessing the environmental and economic effectiveness of environmental protection activities, observing environmental protection measures is very important for this industry and society as a whole.

Environmental issues raised during Moscow electoral campaigns (2013 – 2019)
Authors: Andreev Igor
Published: December 2019

The report analyzes the positions of the main political parties of Russia on the content, causes and ways to overcome the environmental problems of the capital region. During the discussions preceding the elections of Moscow authorities in 2013-2019, political parties and their candidates pointed to such acute environmental problems as air pollution, lack of adequate technologies for processing household waste, degradation of water bodies, reduction of green space. The author draws attention to the difference in the methods of coverage of environmental issues by Progovernment and opposition candidates. Pro-governmental candidates sought to draw the attention of the citizens to the obvious positive results of their previous activities and plans for future. However, these seemingly trivial approaches were based on a very detailed long-term urban strategy of the New environmental policy adopted by the government of Moscow in 2014 and designed for the period up to 2030. Opposition candidates emphasized the extreme severity of environmental problems, harshly criticized the environmental policy of the city administration, tried to identify social and class groups that impede the implementation of effective environmental measures. As a result, the positive proposals of the opposition were more «multidimensional», including several measures to rationalize and democratize the decision-making process in the environmental sphere and to undermine the capacity of social agents who prevented overcoming the environmental crisis in the capital.

Authors: Bitjukova Anna , Markovskaya Elizaveta , Bruz Vladimir , Vititnev Sergey
Published: December 2019

The study is about the relation between the financial leverage and the value of a firm in the chemical industry. Financial stability (low level of growth and financial health) is considered as a factor that can influence the relation. The panel data analysis of the sample of public chemical companies is used. Instrumental variables are used to avoid endogenity problem of the leverage in the model. We find that the relation between the financial leverage and the value is positive. We show that the big amounts of debt past the optimum level influence company’s market value negatively. We also find that financial stability influences the relation between the leverage and the value only partly. Financial health strengthens the relation while growth has little or no influence on the relation. Testing for the change of influence patterns before and after financial crisis of 2008 gives significant difference only in relation between the value and the square financial leverage. In the first part of this work the existing body of literature on the relation between the financial leverage and the value of a company will be studied and hypotheses will be formulated. The second part will be dedicated to methodology of the study. The third part will contain the description of the data and the results of econometric analysis.

Published: December 2019

Fission-fragment mass and total-kinetic-energy distributions following fission of the fermium isotopes 256,258,260Fm at low excitation energy have been calculated using the Brownian shape-motion model. A transition from asymmetric fission in 256Fm to symmetric fission in 258Fm is obtained. The total-kinetic-energy distributions for the three isotopes show radically different behaviour due to varying contributions from different fission modes, with a double-humped distribution for 258Fm.

A detailed comparative study of the sub-barrier fusion of the two near-by systems 36S+50Ti,51V was performed at the National Laboratories of Legnaro (INFN). Aim of the experiment was the investigation of possible effects of the non-zero spin of the ground state of the 51V nucleus on the sub-barrier excitation function, and in particular on the shape of the barrier distribution. The results sh w that the two measured excitation functions are very similar down to the level of 20 - 30 μb. The same is observed for the two barrier distributions. Coupled-channels calculations have been performed and are in good agreement with the experimental data. This result indicates that the low-lying levels in 51V can be interpreted in the weak-coupling scheme, that is, 51V(I) = 50Ti(2+)⊗ p(1 f7/2).
Recent applications of the subtracted SRPA approximation
Authors: Gambacurta Danilo
Published: December 2019

The Second Random Phase Approximation (SRPA) is a natural extension of the Random Phase Approximation obtained by introducing more general excitation operators where two particle-two hole configurations, in addition to the one particle-one hole ones, are considered. Only in the last years, large-scale SRPA calculations, without usually employed approximations have been performed. The SRPA model corrected by a subtraction procedure designed to cure double counting issues and the related instabilities has been recently implemented and applied in the study of different physical cases. We report here on some of the most recent results obtained by using this model. In particular, results on the dipole strength 48Ca and on a systematic study of the isoscalar giant quadrupole resonance in spherical nuclei will be shown and discussed.
Intertwined quantum phase transitions in the Zr chain
Authors: Gavrielov N. , Leviatan A. , Iachello F.
Published: December 2019

We introduce the notion of intertwined quantum phase transitions (IQPTs), for which a crossing of two configurations coexists with a pronounced shape-evolution of each configuration. A detailed analysis in the framework of the interacting boson model with configuration mixing, provides evidence for this scenario inthe Zr isotopes. The latter exhibit a normal configuration which remains spherical along the chain, but exchanges roles with an intruder configuration, which undergoes first a spherical to prolate-deformed [U(5)→SU(3)] QPT and then a crossover to γ-unstable [SU(3)→SO(6)].

To study the nuclear structure of neutron-rich titanium isotopes, a lifetime measurement was performed at the Grand Accélérateur National d'Ions Lourds (GANIL) facility in Caen, France. The nucleiwere produced in a multinucleon-transfer reaction by using a 6.76 MeV/u 238U beam. The Advanced Gamma Tracking Array (AGATA) was employed for the γ-ray detection and target-like recoils were identified event-by-event by the large-acceptance variable mode spectrometer (VAMOS++). Preliminary level lifetimes of the (5/2−) to 13/2− states of the yrast band in the neutron-rich nucleus 53Ti were measured for the first time employing the recoil distance Doppler-shift (RDDS) method and the compact plunger for deep inelastic reactions. The differential decay curve method (DDCM) was used to obtain the lifetimes from the RDDS data.

The inverse-kinematic thick-target method has been used in order to investigate 212Po alpha-structure by the elastic scattering of 208Pb on 4He target. A 208Pb beam, accelerated by the Superconducting Cyclotron (CS) of Laboratori Nazionali del Sud - INFN, at the incident energy of 10.1 A MeV was impinging onto a specifically designed 4He gas cell, two meter long. The gas cell wasacting both as target and as beam degrader, stopping the beam before reaching the alpha-particle detection system placed at 0° with respect to the beam axis. In order to disentangle the elastic contribution from other reaction channels (e.g. inelastic scattering) a microchannel plate was used to measure the Time of Flight(ToF) of both the 208Pb beam particles and the ejectiles along the gas cell. The 208Pbstopping power in the 4He gas target was also measured, as a key ingredient in order to establish theinteraction point inside the gas cell, in turn determining the solid angle covered by the detector. In the following, the experimental technique will be described, and the results of a preliminary data analysis will be shown.

The simulation of heavy ion collisions in the Fermi energy region is a challenge for the theoretical models; in particular it is difficult to obtain a coherent description in all the impact parameter range and to reproduce all the experimental observables. In this contribution we will show the very good job done by the dynamical model AMD [1] followed by the statistical code GEMINI [2, 3] as an afterburner. The model is able to reproduce the main characteristics of peripheral and semiperipheral collisions, although some discrepancies still persist.
Probing the nuclear structure in the vicinity of 78Ni

Published: December 2019

Theoretical and experimental studies of neutron-rich nuclei have shown that the general concept of shell structure is not as robust and universal as earlier thought, but can exhibit significant changes as a function of neutron excess. New magic numbers appear and some other conventional ones disappear mainly because of a different ordering of the single-particle orbitals. In the present contribution, recent experimental studies of neutron-rich Cu isotopes, performed at RIKEN using β decay and one-proton knockout reactions, will be discussed. Neutron-rich nuclei near 78Ni were populated through in-flight fission of 238U on thick 9Be targets in both experiments. In the β-decay study, 75,77Ni nuclei were implanted into the WAS3ABi silicon array, while γ rays from excited states in 75,77Cu emitted after β decay of the implanted ions were detected with the EURICA Ge detector array that was surrounding the active stopper. In a second experiment within the SEASTAR campaign at RIKEN, the same 75,77Cu nuclei were produced in (p,2p) knockout reactions from 76,78Zn beam particles at around 250 MeV/nucleon impinging onto the MINOS liquid hydrogen target. In the latter experiment the DALI2 NaI array was used to detect de-excitation γ rays measured in coincidence with Cu nuclei identified in the Zero Degree Spectrometer. Both studies are complimentary and greatly contribute to our understanding on the nuclear structure in the 78Ni region.

Published: December 2019

The distribution of the spin-dipole strengths in 16O and neutrino-induced reactions on 16O areinvestigated by shell-model calculations with new shell-model Hamiltonians. Chargedcurrent and neutral-current reactioncross sections are valuated in various particle and γ emission channels as well as the total ones at neutrinoenergies up to Eν≈ 100 MeV. Effects of multiparticle emission channels, especially the αp emission channels, on nucleosynthesis of 11B and 11C in core-collapse supernova explosions are investigated. The MSW neutrino oscillation effects oncharged-current reaction cross sections are investigated for future supernova burst. Electron capture rates for a forbidden transition 20Ne(Og.s.+) → 20F(2g.s.+) in stellar environments are evaluated by the multipole expansion method with the use of shell model Hamiltonians, and compared with those obtained by a prescription that treats the transition as an allowed GamowTeller (GT) transition. Different electron energy dependence of the transition strengths between the two methods is found to lead to sizable differences in the weak rates of the two methods.

Elle prévoit d’exploiter industriellement la 4e génération à l’horizon des années 2030 et a déjà lancé la construction d’un démonstrateur de réacteurs à neutrons rapides et d’un démonstrateur d’un réacteur à haute température.

Lückenschluss im Unterkiefer durch Hemisektion der 2. Milchmolaren
Authors: Glockengießer Jörg
Published: December 2019

Bei Nichtanlagen im Unterkiefer müssen sich Behandler und Patient zwischen einem Lückenschluss, einer (implantat)-prothetischen Versorgung oder dem Belassen des Milchzahnes entscheiden. Es bestehen für jede Art der Versorgung Vor- und Nachteile, die in der kieferorthopädischen Literatur seit Jahrzehnten gegeneinander abgewogen werden. Fällt die Entscheidung zu Gunsten eines Lückenschlusses aus, besteht die Möglichkeit, diesen durch frühzeitige Hemisektion des 2. Milchmolars zu erleichtern und die Dauer der späteren Multibrackettherapie zu reduzieren. Der Artikel beschreibt die Methode und verdeutlicht wichtige anhand eines klinischen Beispiels.
Ernährung bei Diabetes mellitus Typ 2

Published: December 2019

Die Ernährung zielt bei Menschen mit Typ-2-Diabetes mellitus (T2DM) nicht ausschließlich auf eine ausreichende Nährstoffversorgung, sondern stellt darüber hinaus, gemeinsam mit Bewegung, die Therapiegrundlage dar 1. Dabei werden meist umfangreiche Empfehlungen bezüglich der Makronährstoffe gegeben (s. Heft 3–2019), während Mikronährstoffe häufig weniger Beachtung finden.
Verumontanum-Mukosahyperplasie als Differenzialdiagnose eines Lokalrezidivs nach radikaler Prostatektomie
Authors: Drosos K. , Köhler G. , Hofmann I. , Kälble T.
Published: December 2019

Eine Verumontanum-Mukosahyperplasie (VMGH) ist eine benigne mikroazinäre proliferative Läsion, die ausschließlich im Verumontanum und in der posterioren Urethra auftritt und die zu den pseudoneoplastischen Imitatoren eines „low risk“ azinären Adenokarzinoms der Prostata zählt. Wir präsentieren den Fall eines 72-jährigen Patienten, bei dem 5 Jahre nach radikaler Prostatektomie wegen Adenokarzinom der Prostata pT2c pN0 cM0 R0, Gleason-Score: 3 + 3 = 6 der bildmorphologische Verdacht eines PSA-negativen Lokalrezidivs 3 × 2 cm im ehemaligen Prostatabett erhoben wurde. Das klinische Bild in Zusammenhang mit der histologischen Diagnostik führten zur Diagnose einer VMGH. Die VMGH ist eine kaum bekannte Differenzialdiagnose zum Lokalrezidiv eines Prostatakarzinoms bei einem PSA im Nullbereich, deren klinisches Bild dargestellt werden soll.
Varikozele im Jugendalter, wenn ja, wann und wie? Kontra OP
Authors: Kliesch Sabine
Published: December 2019

Die verfügbaren Indikatoren, die eine Therapie der Varikozele beim Adoleszenten rechtfertigen sollen, sind unzureichend: Das Hodenvolumen ist als störanfälliger Messparameter variabel, eine Hodenvolumendifferenz kann physiologisch sein; Hodenvolumen und Samenparameter unterliegen der pubertären Entwicklung. Beide Parameter sollten von daher prospektiv und zu mehreren Zeitpunkten gemessen werden, um eine klare Aussage im Hinblick auf eine mögliche Funktionseinschränkung der Hoden durch eine Varikozele treffen zu können. Nahezu unbeachtet sind endokrine Parameter der Hodenentwicklung, die möglicherweise pathologische Abweichungen anzeigen könnten. Völlig unklar ist der postulierte positive Effekt auf die spätere Fertilität der Betroffenen im Erwachsenenalter: Die wenigen vorliegenden Studien können nicht zeigen, dass eine effektive Prävention einer späteren Fertilitätseinschränkung durch eine frühzeitige Therapie der Varikozele beim Jugendlichen möglich ist. Aus diesen Gründen müssen Risiken und Nutzen der Therapie sorgfältig abgewogen werden. Eine evidenzgesicherte Empfehlung zur Intervention beim Jugendlichen lässt sich aus der aktuellen Datenlage nicht ableiten.
Gesunde Kinder durch Hydrotherapie nach Kneipp
Authors: Gündling Peter W.
Published: December 2019

Die naturheilkundliche Behandlung von Kindern mit Phytotherapeutika, Homöopathika und mikrobiologischen Präparaten ist vielen geläufig und wird entsprechend oft angewendet. Teils aus Unkenntnis, teils unter der Annahme, es sei umständlich oder schwierig, sind hydrotherapeutische Maßnahmen dagegen eher wenig verbreitet. Außer Hals- und Wadenwickeln und ggf. Inhalationen werden hydrotherapeutische Anwendungen kaum durchgeführt. Dabei lohnen sich physikalische Anwendungen gerade bei Kindern aufgrund der besseren Regulationsfähigkeit und Selbstheilungskräfte.
Enantioselective Addition of Alkynyl Esters and Ethers to Aldehydes Catalyzed by a Cyclopropyl Amino Alcohol Based Zinc Catalyst
Authors: Zhou Yun , Wang Lifeng , Li Shuoning , Ma Sijie , Walsh Patrick J. , Bian Qinghua , Li Fengqi , Wang Min , Zhong Jiangchun
Published: December 2019

A novel and highly enantioselective synthesis of hydroxyalkynyl esters and ethers through the asymmetric addition of alkynyl esters or ethers to aldehydes promoted by a cyclopropyl amino alcohol based zinc catalyst has been developed. The method afforded a library of new enantioenriched hydroxyalkynol esters and ethers (up to 93% yield; 95% ee), and it was compatible with a broad range of functional groups. Moreover, it could be used in the synthesis of carbon-chain-elongated enantioenriched hydroxyalkynol esters and (2R,5R)-musclide-A1, a cardiotonic potentiating principle from musk.
A Convenient One-Pot Synthesis of Both Enantiomers of 1,3,5-Trisubstituted Hydantoins
Authors: Han Gun Hee , Kim Seo Yun , Lee Ha Rim , Lee Ji Su , Park Yong Sun
Published: December 2019

A novel one-pot asymmetric synthetic method for the direct conversion of bromoacetates into highly substituted hydantoins has been developed. Both enantiomers of 1,3,5-trisubstituted hydantoins were conveniently synthesized through a dynamic kinetic resolution of bromoacetates derived from either ethyl l-lactate or diacetone-d-glucose. The sequential three-component reaction permitted the preparation of (R)- or (S)-1,3,5-trisubstituted hydantoins in yields of 77–51% with enantiomeric ratios of up to 95:5.
One-Pot Deprotonative Synthesis of Biarylazacyclooctynones
Authors: Hioki Yuto , Itoh Mayu , Mori Atsunori , Okano Kentaro
Published: December 2019

Deprotonative formation of biarylazacyclooctynone (BARAC) from the corresponding enol triflate is described. The reaction furnished the azacyclooctynone within one hour at –78 °C. This process could be performed in one pot from the starting ketone to provide a range of BARAC derivatives in moderate to excellent yields. The protocol enabled the gram-scale formation of the BARAC skeleton by reducing the number of reaction steps. Furthermore, the established method was applied to the synthesis of the BARAC derivative bearing a coumarin moiety.
