The giant effect of magnetic ordering on a sound velocity in a sigma-Fe55Cr45 alloy

We studied atomic dynamics of sigma-Fe(100-x)Cr(x) (x=45 and 49.5) alloys using nuclear inelastic scattering of synchrotron radiation. For the sigma-Fe55Cr45 alloy, the derived reduced iron-partial density of phonon states reveal a huge difference in the low-energy region between magnetic and paramagnetic states. The latter implies a ca.36% increase of the sound velocity in the magnetic phase, which testifies to a magnetically-induced hardening of the lattice.Comment: 8 pages, 3 figures, 17 reference

Philosofy as an element of national culture

The report focuses on the role of philosophy in public culture, as well as the analysis of philosophy of the Soviet period. Shows directed evolution of nature and society, indicating the presence of self-regulatory processes. Identified the lack of understanding of self-management within the framework of dialectical materialism and the fallacy of the materialist conception of history is subjective laws of historical materialism. Materialistic delusions of historical materialism overcome in the concept of a regulatory mechanism for the development of society. It is established that the mind of man and society are the subjects of management, the surrounding Genesis - control object. The limitations of dialectical materialism, as well as the mistakes and errors of historical materialism mean the loss of their scientific value. The necessity of development of the common materialistic regulatory dialectic philosophy, which is based on materialism associated with the understanding of the primacy of matter and secondary consciousness, self-governing nature of the interaction of the elements of nature and society, as well as the system of laws of dialectics, which will provide scientific philosophical understanding of the development of life.Доклад посвящён роли философии в общественной культуре, а также анализу философии советского периода. Показано направленное развитие природы и общества, свидетельствующее о наличие самоуправляемых процессов. Выявлено отсутствие понимания самоуправляемости в рамках диалектического материализма и ошибочность материалистического понимания истории – субъективной закономерности истмата. Материалистические заблуждения истмата преодолены в концепции регулятивного механизма развития общества. Установлено, что сознание человека и общества являются субъектами управления, окружающее бытие – объектом управления. Ограниченность диамата, а также ошибки и заблуждения истмата означают потерю ими научного значения. Показана необходимость развития единой материалистической регулятивно – диалектической философии, в которой основой является материализм, связанный с пониманием первичности материи и вторичности сознания, самоуправляемый характер взаимодействия элементов природы и общества, а также системные закономерности диалектики, что обеспечит научность философского осмысления развития бытия

A behavior model of the viscoelastic system with a melting component under load

A numerical investigation of a stressed-strain state powder mixture with a melting component is carried out for the conditions of one-axial loading and nonstationary heating. The state of plane stress was assumed. The influence of the coupling between thermal and mechanical processes on temperature, stress and strains fields was investigated

Two-temperature model of gas combustion in a model burn device of the cylindrical form

The two-temperature model of gas combustion in a porous body of cylindrical heat-generator has been offered and numerically analyzed. Heat exchange between solid frame and gas; burning products interaction with heat-exchanger; distinction of diffusion speeds and heat conductivity in the gas phase are considered in the model. The influence of model parameters on characteristics of stationary modes of gas combustion for various heat exchange conditions of porous torch with heat exchanger is investigated. The results of numerical research do not contradict with observable laws that indicates the opportunity of model use for statement and solving the problem of work optimization of the real burning device

Some problems oh international relations

Доклад посвящён анализу межнациональных отношений. Рассмотрены основные понятия: патриотизм, национализм, шовинизм. Выявлена роль захватнических войн, а также волн людских перемещений в межнациональных отношениях. Отмечено значение осознанного выбора управленческих решений в межнациональных отношениях. К миграционным процессам отнесены процессы колонизации, источником которых являлись государства Европы, а также Россия. Главными причинами межнационального противостояния являются материальные, религиозные и социально-экономические – идеологические разногласия, выраженные в политическом интересе взаимодействующих государств. Представлен положительный пример развития интернациональных отношений в Советском Союзе. Показана роль регулятивного механизма общественного развития в межнациональных процессах, а также возможность воспитания интернациональных отношений, путём изменения менталитета общества, возможного при некапиталистическом пути развития. Обоснована необходимость благожелательного отношения к гастарбайтерам, приезжающим в РФ.The report is devoted to the analysis of international relations. The basic concepts: patriotism, nationalism, chauvinism. The role of aggressive wars and waves of human movements in international relations. The importance of informed choice of management decisions in international relations. To migration processes related processes of colonization, the source of which was the state of Europe and Russia. The main causes of ethnic conflicts are material, religious and socio-economic - ideological differences expressed in the political interest of the interacting States. Presents a positive example of the development of international relations in the Soviet Union. Shows the role of the regulatory mechanism of social development in international processes, and the ability of education international relations, by changing the mentality of society possible with non-capitalist path of development. The necessity of a benevolent attitude to migrant workers coming to Russia

Pressure-induced changes of the vibrational modes of spin-crossover complexes studied by nuclear resonance scattering of synchrotron radiation

Nuclear inelastic scattering (NIS) spectra were recorded for the spin-crossover complexes STP and ETP (STP = [Fe(1,1,1-trisf[N-(2-pyridylmethyl)-N-methylamino]methylg- ethane)](ClO4)2 and ETP = [Fe(1,1,1-trisf[N-(2-pyridylmethyl)-N-methylamino]methylg-butane)](ClO4)2) at 30 K and at room temperature and also at ambient pressure and applied pressure (up to 2.6 GPa). Spin transition from the high-spin (HS) to the low-spin (LS) state was observed by lowering temperature and also by applying pressure at room temperature and has been assigned to the hardening of iron-bond stretching modes due to the smaller volume in the LS isomer
