Hydrodynamic and elastic interactions of sedimenting flexible fibers
NASA Astrophysics Data System (ADS)
Ekiel-Jezewska, Maria L.; Bukowicki, Marek
2017-11-01
Dynamics of flexible micro and nano filaments in fluids is intensively investigated in many laboratories, with a perspective of numerous applications in biology, medicine or modern technology. In the literature, different theoretical models of elastic interactions between flexible fiber segments are applied. The task of this work is to examine the impact of a chosen elastic model on the dynamics of fibers settling in a viscous fluid under low Reynolds number. To this goal, we construct two trumbbells, each made of three beads connected by springs and with a bending resistance, and we describe hydrodynamic interactions of the beads in terms of the Rotne-Prager mobility tensors. Using the harmonic bending potential, and coupling it to the spring potential by the Young's modulus, we find simple benchmark solutions: stable stationary configurations of a single elastic trumbbell and a fast horizontal attraction of two elastic trumbbells towards a periodic long-lasting orbit. We show that for sufficiently large bending angles, other models of bending interactions can lead to qualitatively and quantitatively different spurious effects. We also demonstrate examples of essential differences between the dynamics of elastic dumbbells and trumbbells. This work was supported in part by Narodowe Centrum Nauki under Grant No. 2014/15/B/ST8/04359.

Radiation hydrodynamic effects in two beryllium plates with an idealized aluminum joint
DOE Office of Scientific and Technical Information (OSTI.GOV)
Belkov, S.A.; Mkhitarian, L.S.; Vinokurov, O.A.
A beryllium capsule formed from two hemispherical shells with a thin bond is one possible ignition target for the National Ignition Facility [J. A. Paisner {ital et al.}, Laser Focus World {bold 30}, 75 (1994)] Nonuniformities in density, opacity, and interface position at the joint between these hemishells will initiate two-dimensional (2-D) perturbations of the shock wave and material behind the shock as the shock passes through the shell perpendicular to the joint width. Rarefaction of material flow behind the shock front can cause the interface between the shell and joint material to oscillate in position. The amplitude of thesemore » oscillations may be comparable to the joint width. The evolution of these perturbations is studied by numerically simulating shock passage through flat beryllium plates containing aluminum joints. Using the MIMOSA-ND code [D. Sofronov {ital et al.}, Vopr. At. Nauki Tekh., Ser: Mat. modelirovanie fizicheskih processov {bold 2}, 3 (1990)] two different cases are calculated{emdash}a wide (10 {mu}m) and a narrow (1 {mu}m) joint of aluminum between two 150 {mu}m long semiinfinite beryllium plates. Both cases showed good agreement with an analytic representation of the oscillation behavior. For the narrow joint, a special technique allows the calculation of mixing between the joint and surrounding material caused by the Kelvin{endash}Helmholtz instability. {copyright} {ital 1999 American Institute of Physics.}« less

The idea of revitalization, which grew out of the need to repair degraded urban spaces, has taken on a new meaning in the context of contemporary development challenges. The work includes references to the basic programme documents and strategies. It shows regeneration activities carried out in Wrocław in connection with the organization of international events, cultural and sport events, and with the improvement of spatial order. These actions contributed to the revitalization of the image of the city. The paper contains the results of these changes, the complementarity of decisions and their impact on social behaviour. Idea rewitalizacji, wyrosła z konieczności naprawy zdegradowanych przestrzeni miejskich i zniesienia konfliktów społecznych, nabrała nowego znaczenia w kontekście współczesnych wyzwań rozwojowych. Władze Wrocławia opracowały strategię i szereg dokumentów programowych, których efektem są zrealizowane przedsięwzięcia rewitalizacyjne: obiekty stanowiące infrastrukturę techniczną dla realizacji imprez sportowo - kulturalnych (Stadion Miejski Euro 2012, obiekty Hali Stulecia, rozwoju nauki: kampusy uczelni wyższych i obiekty kultury). Rewitalizacji przestrzennej zostały poddane przestrzenie publiczne miasta: ulice i place, modernizacji i rozbudowie podlegały układy i obiekty transportowe: nowy terminal lotniczy, przebudowa Dworca Głównego we Wrocławiu. Działania rewitalizacyjne wpłynęły na nowy wizerunek miasta, podniosły jakość życia i wyzwoliły nowe zachowania społeczne. Praca zawiera wyniki tych przemian, komplementarności podjętych decyzji i ich wpływu na zachowania społeczne.

We have studied the carbonate-siliceous section of paleooceanic Albian-Cenomanian deposits on the Kamchatsky Mys peninsula (Eastern Kamchatka, Russia) [1].The section is represented by a rhythmic alternation of planktonic limestones and jaspers, accumulated in the open ocean environment. The rhythmicity can be attributed to climate variations that reflect a fluctuation of astronomical parameters (Milankovitch cycles) [2, 3].The section contains two beds enriched in organic carbon, corresponding to the two oceanic anoxic events - MCE and OAE2 [3]. The maximum content of organic matter in those beds reaches 68%. Our geochemical studies revealed an enrichment of the carbonaceous rocks in some major and trace elements including PGE, in comparison with the surrounding limestone and jasper [4].The accumulation of the ore elements in carbonaceous beds is caused by euxinic conditions during sedimentation.The content of uranium, yttrium, and rare earth elements in carbonaceous rocks is up to 60, 142 and 312 ppm respectively. Phosphate grains (bone detritus) with microinclusions of yttrium and uranium minerals were revealed in the carbonaceous rocks using the scanning electron microscope. These data prove the hypothesis of the sorbtion of U and Y by phosphate detritus from seawater. Microprobe analysis also showed an increased content of Cu, Zn, V in some pyrite framboids, which indicates that these elements are fixed in rocks by Fe-sulphide phase or organic matter under euxinic conditions. Our research may bring us closer to understanding the mechanism of syngenetic accumulation of metals in the black shales. This work was supported by the RFBR (No. 16-05-00546).

terrestrial glaciers and Martian North Polar Residual Cap. 3) Students were responsible for physically preparing scientific equipment (within a given budget). 4) Students prepared detailed procedures which were used during the experiment. The experiment was performed by the Austrian Space Forum analog astronauts during the Mars Analog Mission AMADEE-15 between 2nd and 14th of August 2015 at the Kaunertal Glacier in Austria. 5) During and after the mission students analyzed data collected during the experiment. 6) Students presented their findings during the regional science fair (Dolnoslaski Festiwal Nauki). Despite the fact the quality of the data produced during the experiment was not satisfactory, the project was a success in terms of explaining students "How Science Really Works" (e.g., how much depends on the properly designed and executed procedures).

The paper is dedicated to the outstanding French astronomer and the popular writer of science Camille Flammarion (1842-1925) whose 160th birthday anniversary was celebrated in 2002. The path in life of Flammarion, his astronomical works, his works as a popular writer and a publisher are considered in detail. The out-of-date appreciation of his role in astronomy is critically rejected and a new appreciation of his versatile activity as a great enlightener and researcher is given.

residence patterns that have emerged over centuries. Well - preserved and protected excavations are the relics of the past, are part of the cultural heritage and become a rich source of knowledge about history. Ostanie lata przyniosły rozwój skoncentrowany na maksymalizacji zysków ekonomicznych i politycznych. Doprowadził on do kryzysów środowiskowych, społecznych, a nawet gospodarczych. Przyczyniło się to do powstania koncepcji zrównoważonego rozwoju. Jest to dążenie do poprawy jakości życia przy zachowaniu równości społecznej, bioróżnorodności i bogactwa zasobów naturalnych. Bardziej świadome i aktywne społeczeństwo ma do odegrania kluczową rolę w zrównoważonym rozwoju. Z jednej strony jest regulatorem wpływu gospodarki na środowisko, zaś z drugiej kapitał społeczny zapewnia ciągłość wizji rozwoju i planowania jej realizacji. Ochrona zabytkowych podziemi bardzo dobrze wpisuje sie w proces zrównoważonego rozwoju. Zachowane i udostępnione zabytkowe podziemia są częścią dziedzictwa kulturowego i mają za zadanie zachowania wartości historycznych, kulturowych, przyrodniczych, a także użytkowych. W ostatnich latach obserwuje się intensywny rozwój działań zmierzających do wykorzystania zabytkowych podziemi do celów użytkowych. Problem rewitalizacji zabytkowych podziemi, a więc przywracanie "do życia" starych wyrobisk, jest bardzo skomplikowanym procesem przywracania pierwotnych funkcji nieczynnym lub zdegradowanym obiektom podziemnym. W procesie projektowania bardzo ważne są działania zgodnie z procesami naturalnymi obowiązującymi w przyrodzie. Zabezpieczane i adaptowane podziemia muszą w rezultacie działań człowieka być "przyjazne" i akceptowane przez użytkowników, będąc elementem ochrony dziedzictwa kulturowego człowieka, a więc częścią składową zrównoważonego rozwoju. Problemy techniczne występujące przy adaptacji zabytkowych podziemi są nie tylko praktycznym zastosowaniem nauki, ale tak
