Separation of Q from carbon in CR meteorites during stepped combustion

Introduction: The nature of the planetary noble gas carrier (Q) in meteorites remains uncertain. It is known that it is likely to be carbonaceous, but represents only a small fraction of the total macromolecular material. Q is oxidisible with nitric and other oxidizing acids. It seems to be partly destroyed with pyridine and may have an organic structure. Previously, we have shown that during parent body thermal metamorphism Q is less affected than the majority of other carbonaceous materials. If organic matter is graphitized, as has happened in the enstatite chondrite parent bodies, Q remains unaffected. In the present study we have found that Q is also separable from the majority of carbon in type 2 and 3 CR chondrites during stepped combustion. It is possible that this is because Q has become encased within the matrix, in contrast to other carbon phases, during parent body metamorphism

Controlled light-matter coupling for a single quantum dot embedded in a pillar microcavity using far-field optical lithography

Using far field optical lithography, a single quantum dot is positioned within a pillar microcavity with a 50 nm accuracy. The lithography is performed in-situ at 10 K while measuring the quantum dot emission. Deterministic spectral and spatial matching of the cavity-dot system is achieved in a single step process and evidenced by the observation of strong Purcell effect. Deterministic coupling of two quantum dots to the same optical mode is achieved, a milestone for quantum computing.Comment: Modified version: new title, additional experimental data in figure

ФУНКЦИОНАЛЬНАЯ ОЦЕНКА ДВИЖЕНИЯ КАК СРЕДСТВО СНИЖЕНИЯ ТРАВМАТИЗМА В ФИТНЕСЕ

Aim. Nowadays, the issue of increasing the overall effectiveness of workout programs, physical training, and rehabilitation, as well as reducing the risk of injury in active people remains acute. This is due to the fact that the number of people engaged in motor activity is constantly growing every year. The use of functional movement screening is aimed at identifying potential risks of injuries and ways to reduce their number, as well as developing an individual training program that will help to ensure active lifestyle. Materials and methods. During 2018, a study was conducted with people aged from 38 to 51 years who scored less than 14 in the FMS test (58 out of 200 people). The study is based on the domestic and foreign theory of sports training. The foreign experience of using functional movement screening was also taken into account. Research methods: literature analysis, testing, pedagogical experiment, mathematical and statistical processing. The testing process itself is based on functional movement screening (FMS). Results. It was found that at the beginning of the study the average FMS score was 9.88 points out of 21 possible (which implies the risk of injury according to the study of American colleagues). After 3.5 months, a significant improvement was achieved (more than 14 points on average). In the group engaged in fitness, there was a decrease in the number of injuries. Conclusion. The study confirmed the effectiveness of the FMS testing system, as well as the use of proposed exercises. The downward trend in the risk of injuries indicates the correctly chosen strategy. The simplicity and availability of the method also indicates its feasibility for the training process with persons involved in fitness. © 20202 South Ural State University - Institute of Sport, Tourism and Service.

POWER TRAINING OF STUDENTS WITH THE HELP OF WEIGHT FITNESS IN PHYSICAL EDUCATION CLASSES

The methodology of strength training of students is presented in order to increase the level of knowledge and increase the level of knowledge and improve the level of knowledge. The article describes that physical exercise is one of the most effective means of developing physical qualities in a person. And strength training with weights is one of the best ways to in-crease the students' strengths and motivation for pursuing classes with them. Statement of the relevance of the problem of low motor activity of youth, which leads to the success of quality and a drop in health. It is noted that weight lifting exercises contribute to the positive mood of students and high interest among students, as they can observe their progress in the process of classes. The pedagogical experiment, which was conducted on the basis of the Ural Pedagogical University, is described in detail.Представлена методика силовой тренировки студентов в целях увеличения интереса и мотивации к занятиям физической культурой и повышения уровня здоровья молодежи. Статья описывает, что одним из эффективных средств развития физических качеств у человека является физические упражнения. А силовая тренировка с гирями – один из лучших способов увеличения силовых способностей студентов и мотивации к занятиям у них. Излагается актуальность проблемы низкой двигательной активности молодежи, которая приводит к снижению физических качеств и падению здоровья. Отмечено, что занятия гиревым фитнесом способствуют положительному настрою занимающихся и высоким интересом у студентов, так как они могли наблюдать свой прогресс в процессе занятий. Подробно описывается педагогический эксперимент, который проводился на базе Уральского педагогического Университета

Thermobaric synthesis, structure, and properties of Dy x Cu 3V4O12

The perovskite-like compound Dy x Cu3V 4O12 (x = 0.67-0.75) is synthesized under high pressure (P = 4.0-9.0 GPa) and temperature (T = 1000 C). Its crystal structure is determined (Im-3 space group, Z = 2, a = 7.29348(7) Å) by means of powder X-ray diffraction. The basic lengths and bond angles are defined. It is found that the high-pressure phase of Dy x Cu3V 4O12 is characterized by metallic conductivity and paramagnetic properties. © 2013 Allerton Press, Inc

Tensor analyzing power Ayy in deuteron inclusive breakup at large Pt and spin structure of deuteron at short internucleonic distances

The Ayy data for deuteron inclusive breakup off hydrogen and carbon at a deuteron momentum of 9.0 GeV/c and large Pt of emitted protons are presented. The large values of Ayy independent of the target mass reflect the sensitivity of the data to the deuteron spin structure. The data obtained at fixed $x$ and plotted versus Pt clearly demonstrate the dependence of the deuteron spin structure at short internucleonic distances on two variables. The data are compared with the calculations using Paris, CD-Bonn and Karmanov's deuteron wave functions.Comment: 4 pages, 2 figures, talk given at the SPIN2004 Conf., 10-16 Oct. 2004, Triest, Ital
