Opis:: В статье рассматриваются два произведения Иосифа Бродского начала 1960-х гг. – поэма Зофья и стихотворение «Лети отсюда, белый мотылек…», посвященное тому же адресату. Делается предположение, что стихотворения Бродского, посвященные Зофье Капущиньской (Z. K.) или обращенные к ней, складываются в своего рода гипертекст с единым набором образов, мотивов и подтекстов – «Зофьин текст». В статье приводятся некоторые факты биографии поэта, послужившие толчком к возникновению «Зофьина текста» и проводится сопоставительный анализ указанных произведений, весьма несхожих по форме и содержанию. Руководствуясь методическими принципами, использованными Владимиром Топоровым в его исследовании «Лизина текста» русской литературы, автор выявляет концептуальные особенности стихотворения и показывает, как все они были воспроизведены и развиты в поэме. Не ставя задачи всестороннего анализа текста, автор ограничивается рассмотрением некоторых лексических и лексико-грамматических средств, интерпретацией некоторых образов и мотивов и выявлением смыслообразующих подтекстов, которые могут быть приняты как дифференциальные признаки, на основе которых возможно формирование гипертекста. Представляется, что статья может послужить основой для анализа других компонентов гипотетического «Зофьина текста», а также для его расширения путем выявления обнаруженных дифференциальных признаков в других произведениях Бродского.
The paper discusses two pieces of poetry from the early period of Iosif Brodsky’s creative work (early 1960s): the long poem Zofia and the 16-line verse “Leti otsiuda, belyi motyljok…” [En. “Fly away from here, white moth…”], dedicated to the addressee referred to in “Zofia”. The presumption is that Brodskii’s verses dedicated or referring to his Polish friend Zofia Kapuścinska (Z. K.) form a kind of hypertext with a single set of images, motifs, and subtexts, which, according to Vladimir Toporov’s terminology, may be defined as the “Zofia’s Text”. The paper presents some facts from the poet’s biography that gave rise to the “Zofia’s Text” and provides a comparative analysis of the two mentioned works. Guided by Vladimir Toporov’s methodological principles used in his study of the “Liza’s Text” in Russian literature, the author points out the conceptual features of “Leti otsiuda, belyi motyljok…” and shows how all of them were later reproduced and elaborated in “Zofia”. Without making it her aim to undertake a comprehensive analysis of the texts, the author confines herself to considering some lexical and lexical-grammatical means, interpreting some images and motifs, and identifying some sense-forming subtexts that can be taken as differential features characteristic of the assumed hypertext.

Opis:: Metamict minerals contain radioactive elements that degrade the crystal structure of the minerals. The degradation occurs primarily through progressive overlapping recoil nuclei collision cascades from α-decays of $\text{}^{238}U$, $\text{}^{232}Th$, $\text{}^{235}U$ and their daughter products. We report the results of $\text{}^{57}Fe$ Mössbauer spectroscopy, gamma-ray spectrometry and microprobe analysis of three partially metamict allanites, $(Ca,Ce,REE)_2(Fe^{2+},Fe^{3+})$$(Al,Fe^{3+})_2O[Si_2O_7][SiO_4](OH)$ where REE stands for rare earth elements. The samples were collected in pegmatites from Reno, Nevada (USA), Franklin, New Jersey (USA) and Nya Bastnas Field (Sweden). The absorbed α-dose for these minerals was found to range from $5.8×10^{14}$ α-decay/mg for the allanite from Reno to $1.9×10^{15}$ α-decay/mg for the allanite from Franklin. The Mössbauer spectra show a decrease in the $Fe^{2+}$ doublet intensity with increasing absorbed α-dose. We also observe an increase in the line widths of the $Fe^{2+}$ and $Fe^{3+}$ doublets with increasing absorbed α-dose.

Opis:: The paper presents various designs of several medium and small size Dense Plasma Focus (DPF) chambers intended for numerous applications, a description of technologies used in these facilities, and some results reached with these devices by using a number of diagnostic techniques. In present experiments the DP foci have been used mainly as an X-ray source. We discuss here how it is possible to satisfy absolutely new and very strict demands on the construction and technology for the devices to be eventually applied in science and industry. Between these characteristics there are a high repetition rate (typically 1…15 Hz) and a long lifetime (over 1 million shots). Their switching elements, a collector and chambers must withstand a high quasi-continuous heat load (up to 100 kW). High energy density in the central part of the chamber anode and the necessity to provide a channel for radiation extraction demanded a special construction and specific materials implementation in this region. Their X-ray spectrum should be tuned. They have to operate with different working gases and preferably in a wide range of pressures. All these points are discussed in this report. Capabilities of the described techniques are illustrated by results of the recent experimental studies carried out with facilities located at the Nanyang Technological University (NX1) as well as at the Lebedev Physical Institute (PF-0.2).

Opis:: The oxidation of 1,1-dimethylhydrazine with aqueous monochloramine yielded (E)-1,1,4,4-tetramethyl-2-tetrazene (1) as a pale yellow liquid with hypergolic properties. 1 can be oxidized with potassium permanganate to form (E)-1-formyl-1,4,4-trimethyl-2-tetrazene (2) and (E)-1,4-diformyl-1,4dimethyl-2-tetrazene (3). Additionally, 1 reacts with a diethyl ether solution of monochloramine to form a stable 1,1,4,4-tetramethyl-2-tetrazenium chloride salt (4). The chloride in salt 4 was exchanged with various energetic anions, such as nitrate (5), perchlorate (6), 5,5´-azobistetrazolate (7*6H2O), picrate (8) and azide (9). All materials were characterized by analytical and spectroscopic methods and the solid state structures of compounds 2-8 were elucidated. Due to the energetic nature of these materials, they were submitted to friction and impact sensitivity tests and DSC analysis was used to assess their thermal stabilities. Furthermore, the heats of formation of compounds 2-8 were computed using quantum mechanical methods (CBS-4M) and their detonation parameters (pressure and velocity) and specific impulses were also calculated. Lastly, the 2-tetrazene derivatives presented here are of potential interest either as building blocks or as a new class of low toxicity, low sensitivity energetic materials.

Opis:: An explicit analysis conducted on the crack behavior in chirurgical cement (Polymethylmethacrylate – PMMA) used for Total Hip Prosthesis (THP) is of great importance in collecting information about the nature of the phenomenon of loosening of the cement application. The rupture of the orthopedic cement is practically the main cause of this loosening. Understanding diﬀerent rupture mechanisms give a great value in advancing the durability of the cemented total prosthesis. The purpose of this study is to analyse cracks behavior, initiated in the cement that links the femoral-stem with the bone, using the Finite Element Analysis Method (FEM). The present study brings into focus the variation of the stress intensity factor in modes I, II and III. This rupture criterion is used according to the nature of crack, its orientation and its location in the orthopedic cement. At ﬁrst, the level and distribution of the equivalent von Mises stress is analysed, which is induced in the medial, proximal and distal parts of the bone cement. Then, the behavior of diﬀerent geometric forms of an elliptical crack is evaluated which are located and initiated within the body of these three parts.

Opis:: During the transmission of electromagnetic radiation through a medium containing water molecules, portions of the electromagnetic spectrum are absorbed by water molecules. This water absorption occurs preferentially at certain characteristic wavelengths while the balance of the spectrum is transmitted with minimal effects. This characteristic of water provides advantages but also some disadvantages in science and engineering applications. Especially in remote sensing applications, it may cause to produce incorrect information. So identification of behavior of electromagnetic wave in water is significantly important. Some of the studies based on electromagnetic wave behavior in water are bio-medical researches, sensors, transmitters, accumulators, organic-inorganic materials, and microwave ovens. In this paper, based on the water's absorption of electronic wave property, a plastic cup as half-full of water is imaged using near field microwave system. After being processed with 3D-DLL algorithm it is imaged as 3D with IRIS software. A robotic system is used for data collection process. Transmission and reflection measurements of system are done with N5230A network analyzer.

Opis:: Doped vanadate ceramics with general formula Ca3-xInxVO8 were synthesized by using two different precursors ( oxalate & citrates) to get maximum homogeneity inside the bulk of the material where x = 0.05 and 0.25 mole. Structural and microstructural properties were monitoring by using both of XRD and SEM evaluating that indium doped - calcium vanadate ceramic has the semiconducting classical doubly perovskite phase as proved in the X-ray diffractogram, grain size of the material bulk was found to be in between 1.57- 2.23 μm which are lower than those reported in literatures .Magnetic measurements indicated that the In- doped- calcium vanadate ceramic exhibits an semiconducting behavior confirming that indium- hole dopings enhance the paramagnetic character and semi-conduction mechanism of the hexagonal perovskite phase. Furthermore 3D-AFM investigations were made to study effect of indium doping on the surface topology and grain size in the material bulk.

Opis:: 4,6-Diazido-N-(2,4,6-trinitrophenyl)-1,3,5-triazin-2-amine (TNADAzT) and its silver salt (AgTNADAzT) were prepared and characterized. Elemental analysis, FTIR, NMR, DSC, AAS and X-ray diffraction were used for analytical characterization. The sensitivities of TNADAzT and AgTNADAzT were determined and compared with common explosives and MTX-1. The crystal density of TNADAzT is 1.794 g·cm−3 and its heat of formation 899 kJ·mol−1. The sensitivity of TNADAzT to impact and friction slightly exceeds PETN; the sensitivity to electrostatic discharge is lower than RDX. The sensitivity of AgTNADAzT is on the level of a primary explosives (between mercury fulminate and PETN). The initiation efficiency of AgTNADAzT is higher than 200 mg (acceptor PETN compressed by 64-70 MPa) and therefore excludes it from practical use as a primary explosive in detonators.
