Computer simulation of field ion images of nanoporous structure in the irradiated materials

Computer simulation and interpretation of field ion microscopy images of ion irradiated platinum are discussed. Field ion microscopy technique provides direct precise atomic scale investigation of crystal lattice defects of atomically pure surface of material; at the same time it allows to analyze the structural defects in volume by controlled and sequential removal of surface atoms by electric field. Defects identification includes the following steps: at the first stage the type of crystalline structure and spatial orientation of crystallographic directions were determined. Thus, we obtain the data about exact position of all atoms of the given volume, i.e. the model image of an ideal crystal. At the second stage, the ion image was processed used the program to obtain the data about real arrangement of atoms of the investigated sample. At the third stage the program compares these two data sets, with a split-hair accuracy revealing a site of all defects in a material. Results of the quantitative analysis show that shape of nanopores are spherical or cylindrical, diameter on nanopores was varied from 1 to 5 run, their depth was fond to be from 1 to 9 nm. It was observed that nearly 40% of nanopores are concentrated in the subsurface layer 10 nm thick, the concentration of nanopores decreased linearly with the distance from the irradiated surface

Role of direct exchange and Dzyaloshinskii-Moriya interactions in magnetic properties of graphene derivatives: C2_2F and C2_2H

According to the Lieb's theorem the ferromagnetic interaction in graphene-based materials with bipartite lattice is a result of disbalance between the number of sites available for $p_z$ electrons in different sublattices. Here, we report on another mechanism of the ferromagnetism in functionalized graphene that is the direct exchange interaction between spin orbitals. By the example of the single-side semihydrogenated (C$_2$H) and semifluorinated (C$_2$F) graphene we show that such a coupling can partially or even fully compensate antiferromagnetic character of indirect exchange interactions reported earlier [Phys. Rev. B {\bf 88}, 081405(R) (2013)]. As a result, C$_2$H is found to be a two-dimensional material with the isotropic ferromagnetic interaction and negligibly small magnetic anisotropy, which prevents the formation of the long-range magnetic order at finite temperature in accordance with the Mermin-Wagner theorem. This gives a rare example of a system where direct exchange interactions play a crucial role in determining a magnetic structure. In turn, C$_2$F is found to be at the threshold of the antiferromagnetic-ferromagnetic instability, which in combination with the Dzyaloshinskii-Moriya interaction can lead to a skyrmion state.Comment: 10 page

Analysis the Impact of Literature on the Formation of the Russian Federation State Civil Servant Image in Mass Media

The main features of the XXI century Russian society have been formed due to social and psychological changes, which led to a global transformation of the state system. Modern world faces the problem of developing a new policy of state power that will be based on the principles of consensus (reconciliation of all contentious and conflicting issues in the process of developing a solution that is reached through discussion and consultation), society and open partnership. The reason for this global upheaval is that the pace of change in the relationship between the state (government) and society itself depends on the open-ended policy that is now key. The image of a civil servant is similar to a construction that can be replaced, strengthened, re-mounted, modified, etc., and most importantly, that it needs serious work. The perception of the image exists and changes not only in the consciousness of people, but also in the unconscious sphere (emotional). In order to create a positive image of a civil servant, they need to be governed. To manage it, one needs to know the basic idea of what and in what sequence should occur, and at what stage intermediate results should appear. According to the authors, the solution to the problem of studying the acting factors that make the positive image of civil servants of modern Russia, the identification of the most effective ways, forms and principles of its positive transformation, as well as the analysis of the constituents of the employee of state structures are relevant. The most important in the work of representatives of public authorities is the nature of their public relations. If public servants do not evoke citizens' feelings of trust, justice and other positive psychological and social reactions, then feedback (from the population to state bodies) will be ineffective. Since the operation of the system of state power is the result of the functioning of the whole state as a whole, it is important that the work of state bodies used the maximum opportunities with the least cost. This scheme ensures effective management and positive results. But such a situation will not be achievable if the level of public trust in government is low.The main features of the XXI century Russian society have been formed due to social and psychological changes, which led to a global transformation of the state system.

El mundo moderno enfrenta el problema de desarrollar una nueva política de poder estatal que se basará en los principios de consenso (conciliación de todos los temas conflictivos y conflictivos en el proceso de desarrollar una solución que se alcance a través de la discusión y consulta), la sociedad y la asociación abierta. La razón de esta agitación global es que el ritmo de cambio en la relación entre el estado (gobierno) y la sociedad misma depende de la política abierta que ahora es clave.La imagen de un funcionario público es similar a una construcción que se puede reemplazar, fortalecer, volver a montar, modificar, etc., y lo más importante, que necesita un trabajo serio. La percepción de la imagen existe y cambia no solo en la conciencia de las personas, sino también en la esfera inconsciente (emocional). Para crear una imagen positiva de un funcionario público, deben ser gobernados. Para gestionarlo, es necesarioconocer la idea básica de qué y en qué secuencia debe ocurrir, y en qué etapa deben aparecer los resultados intermedios. Según los autores, la solución al problema de estudiar los factores de actuación que hacen la imagen positiva de los funcionarios de la Rusia moderna, la identificación de las formas, formas y principios más efectivos de su transformación positiva, así como el análisis de los componentes del empleado de las estructuras estatales son relevantes. Lo más importante en el trabajo de los representantes de las autoridades públicas es la naturaleza de sus relaciones públicas. Si los servidores públicos no evocan los sentimientos de confianza, justicia y otras reacciones psicológicas y sociales positivas de los ciudadanos, la retroalimentación (de la población a los organismos estatales) será ineficaz. Dado que la operación del sistema de poder estatal es el resultado del funcionamiento de todo el estado en su conjunto, es importante que el trabajo de los organismos estatales aproveche las máximasoportunidades con el menor costo. Este esquema garantiza una gestión eficaz y resultados positivos. Pero tal situación no será posible si el nivel de confianza pública en el gobierno es bajo

Outpatient management of patients with peripheral artery disease by cardiologists or surgeons: influence on the prognosis and prevalence of surgical interventions

Highlights. The study shows for the first time that during the three-year follow-up of patients with diseases of the arteries of the lower extremities in the observation groups of a general surgeon and a cardiologist, adverse events (myocardial infarction, stroke, amputation, disability) and deaths occurred more often in a surgeon than a cardiologist. The study proves the correctness and real benefit of such an approach with the involvement of a cardiologist to the outpatient stage of management of a complex cohort of patients with atherosclerosis of the vessels of the lower extremities.Aim. To study the effect the outpatient observation of patients with peripheral arteries disease (PAD) by cardiologists and surgeons has on timing and prevalence of reconstructive surgery and the prognosis of patients. Methods We analyzed the data on 585 PAD patients who underwent outpatient observation from 2010 to 2017, dividing them into 2 groups. The first group (131 patients) managed by an surgeon; the second (454 patients) managed by a cardiologist. Since the groups were not comparable in terms of the initial parameters, the comparability of patients in the groups (observation by a surgeon or by a cardiologist) was achieved using pseudorandomization. The follow-up period was three years; we assessed the incidence of deaths, adverse events, and the prevalence of reconstructive operations.Results. During a three-year follow-up the 1st group, compared with the 2nd, had more deaths in general (p<0.001), death from cardiac causes (p = 0.045), from stroke (p><0.001), as well as the total number of adverse events (p><0.001) and disability (p = 0.065). Indications for reconstructive surgery on the lower extremities arteries (LEA), and operations frequency were comparatible in groups. Amputation history, taking diuretics, presence of rhythm disturbances, and management by a surgeon increased the risk of adverse outcomes. Management by a cardiologist, reconstructive LEA surgeries, female sex improved the prognosis of patients. Conclusion Observation of PAD patients by a cardiologist contributes to a higher frequency of optimal drug therapy by patients and can reduce the number of adverse events in patients and improve their survival without affecting the timing and frequency of reconstructive LEA surgeries.
