Implication of satellite images in studying potential hydrocarbon resources in the licence Blocks 9 and 11, the exclusive economic zones of Egypt and Cyprus

A frequency-resonance technology was used for processing and decoding the satellite images of the licence Blocks 9 and 11 in the Eastern Mediterranean. The anomalies of “oil and gas” type were revealed in the study area. The supergiant Zohr gas field produces the prominent anomaly covering the largest area of 251 km2. This anomaly evidences for the channels for vertical migration of deep hydrocarbon-bearing fluids and the horizontal gradient in reservoir pressure. For the first time, these two specific findings were suggested to be indicators of a commercial discovery. Based on them, several “oil and gas” type anomalies were recommended for exploration drilling in the Blocks 9 and 11. Available information cannot allow us to consider the Onisiforos discovery as a commercial gas field. The siliciclastic and carbonate plays are equally workable in the Egyptian, Cypriot and Israeli EEZs where in the Miocene sediments abiogenic methane is the main component of gas which ascends to reservoirs from deeper layers. Selecting an optimal drilling location requires an interdisciplinary approach.Використано частотно-резонансну технологію для обробки і декодування супутникових знімків ліцензійних блоків 9 і 11 у Східному Середземномор.ї. У досліджуваному районі виявлено аномалії типу .нафта і газ.. Супергігантське газове родовище Зохр зумовлює чітку аномалію площею 251 км2. Цій аномалії відповідає наявність каналів вертикальної міграції глибоких вуглеводневих флюїдів і горизонтальний градієнт пластового тиску в резервуарі родовища. Вперше запропоновано використовувати ці дві характерні особливості як індикатори рентабельності перспективної структури. На їх основі для розвідувального буріння було рекомендовано кілька аномалій типу .нафта і газ. у блоках 9 і 11. Наявна інформація не дає змоги розглядати перспективну структуру Онісіфор як рентабельне газове родовище. Силіцикластична і карбонатна моделі розвідувальних робіт однаковою мірою ефективні у єгипетській, кіпрській та ізраїльській ексклюзивних економічних зонах. У них абіогенний метан є основним компонентом газу, що піднімається до пасток з глибших шарів. Вибір оптимального місцеположення буріння потребує міждисциплінарного підходу

Double giant resonances in deformed nuclei

We report on the first microscopic study of the properties of two-phonon giant resonances in deformed nuclei. The cross sections of the excitation of the giant dipole and the double giant dipole resonances in relativistic heavy ion collisions are calculated. We predict that the double giant dipole resonance has a one-bump structure with a centroid 0.8 MeV higher than twice energy for the single giant dipole resonance in the reaction under consideration. The width of the double resonance equals to 1.33 of that for the single resonance.Comment: 5 pages, 2 postscript figure

M1 Resonances in Unstable Magic Nuclei

Within a microscopic approach which takes into account RPA configurations, the single-particle continuum and more complex $1p1h\otimes phonon$ configurations isoscalar and isovector M1 excitations for the unstable nuclei ${56,78}$Ni and ${100,132}$Sn are calculated. For comparison, the experimentally known M1 excitations in ${40}$Ca and $^{208}$Pb have also been calculated. In the latter nuclei good agreement in the centroid energy, the total transition strength and the resonance width is obtained. With the same parameters we predict the magnetic excitations for the unstable nuclei. The strength is sufficiently concentrated to be measurable in radioactive beam experiments. New features are found for the very neutron rich nucleus ${78}$Ni and the neutron deficient nucleus ${100}$Sn.Comment: 17 pages (LATEX), 12 figures (available from the authors), KFA-IKP(TH)-1993-0

Effect of pulse thermal treatments on the Ni(Ti)–n-21R(6H)-SiC contact parameters

We present experimental investigations of the effect of rapid thermal treatment with incoherent IR radiation, as well as electric-spark and electron-beam treatments, on the electric parameters of Ni(Ti) n-21R(6H)-SiC contacts. The results obtained show that pulse thermal treatment is an efficient technique for local change of parameters of heterogeneous metal/silicon carbide structures

Modeling the input of radiation into plane linear waveguides using diffraction gratings for a new technology for the manufacture of waveguide systems

Произведено моделирование и выбор оптимальных параметров дифракционной решётки для новой разработанной технологии изготовления плоских волноводных систем. В отличие от использования готовых пластин «кремний на изоляторе», разработана новая технология изготовления полностью автономной системы ввода излучения, согласующего элемента и собственно волновода. Приведено общее описание технологии системы «ввод излучения – распространение – вывод излучения». Найдены конкретные технологические параметры высоты решётки, подстилающего и покровного слоёв. Эффективность ввода в волновод составила 30 % за счёт подбора оптимального расстояния от волновода до кремниевой подложки, которая работает как зеркальный слой. The numerical simulation and selection of optimal parameters of the diffraction grating for a newly developed technology for the manufacture of plane waveguide systems are performed. In contrast to the use of ready-made silicon wafers on an insulator, the new technology has been developed for the manufacture of a fully autonomous radiation input system, a coupling element and the waveguide itself. A general description of the technology of the ‘radiation input – propagation – radiation output’ system is given. Concrete fabrication parameters of the lattice height, the substrate and coating layers are found. The coupling efficiency of radiation input into the waveguide is found to be 30%

Two-pion Bose-Einstein correlations in central Pb-Pb collisions at sNN\sqrt{s_{\rm NN}} = 2.76 TeV

The first measurement of two-pion Bose-Einstein correlations in central Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV at the Large Hadron Collider is presented. We observe a growing trend with energy now not only for the longitudinal and the outward but also for the sideward pion source radius. The pion homogeneity volume and the decoupling time are significantly larger than those measured at RHIC.Comment: 17 pages, 5 captioned figures, 1 table, authors from page 12, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/388

Suppression of charged particle production at large transverse momentum in central Pb-Pb collisions at sNN=2.76\sqrt{s_{\rm NN}} = 2.76 TeV

Inclusive transverse momentum spectra of primary charged particles in Pb-Pb collisions at $\sqrt{s_{_{\rm NN}}}$ = 2.76 TeV have been measured by the ALICE Collaboration at the LHC. The data are presented for central and peripheral collisions, corresponding to 0-5% and 70-80% of the hadronic Pb-Pb cross section. The measured charged particle spectra in $|\eta|<0.8$ and $0.3 < p_T < 20$ GeV/$c$ are compared to the expectation in pp collisions at the same $\sqrt{s_{\rm NN}}$, scaled by the number of underlying nucleon-nucleon collisions. The comparison is expressed in terms of the nuclear modification factor $R_{\rm AA}$. The result indicates only weak medium effects ($R_{\rm AA} \approx$ 0.7) in peripheral collisions. In central collisions, $R_{\rm AA}$ reaches a minimum of about 0.14 at $p_{\rm T}=6$-7GeV/$c$ and increases significantly at larger $p_{\rm T}$. The measured suppression of high-$p_{\rm T}$ particles is stronger than that observed at lower collision energies, indicating that a very dense medium is formed in central Pb-Pb collisions at the LHC.Comment: 15 pages, 5 captioned figures, 3 tables, authors from page 10, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/98
