La question du sacrifice animal dans les rites funéraires en Gaule belgique
1998
L'etude des necopoles du l'Age du Fer du nord de la Gaule a revele la pratique courante de l'implication de l'animal dans les rites funeraires humains. Cet usage a deja ete analyse dans plusieurs syntheses, mais l'auteur s'interroge en particulier, dans cet article, sur les modalites de choix et d'acquisition des quartiers de viande dedies au rite et donc des modalites du sacrifice animal et propose d'etudier les indices receuillis a ce sujet dans des necropoles lateniennes du nord de la France, recemment fouillees
Cmentarz Sapieżyński w Stanisławowie
2021
This article presents the history of one of the largest Polish cemeteries in the Eastern Borderlands. Thousands of Poles, including artists, poets, writers, sculptors, prominent politicians, local government officials and soldiers fighting for Polish independence in various uprisings, were buried in the Sapieżyński Cemetery during its 200-year-long history. The necropolis was closed down by the Soviet authorities in 1980, and the entire area was bulldozed. Crushed tombstones were transported outside the city, and a theater building and a hotel were developed on the site. The paper recreates the cemetery’s history and tells the life stories of the most prominent individuals who were laid to …
Evolution of an isolated monopole in a spin-1 Bose-Einstein condensate
2016
We simulate the decay dynamics of an isolated monopole defect in the nematic vector of a spin-1 Bose-Einstein condensate during the polar-to-ferromagnetic phase transition of the system. Importantly, the decay of the monopole occurs in the absence of external magnetic fields and is driven principally by the dynamical instability due to the ferromagnetic spin-exchange interactions. An initial isolated monopole is observed to relax into a polar-core spin vortex, thus demonstrating the spontaneous transformation of a point defect of the polar order parameter manifold to a line defect of the ferromagnetic manifold. We also investigate the dynamics of an isolated monopole pierced by a quantum vo…
Megacities without Global Functions.
2007
Present urban evolution is characterized by two major phenomena. On the one hand, the number of very large cities, the megacities, increases dramatically, especially in the less developed countries (LDCs). On the other hand, globalization leads to the emergence of cities coordinating complex and global economic activities, the global cities, especially in the more developed countries (MDCs). So, the two phenomena are diverging. A number of megacities do not exhibit any global function.The global performances of megacities are well correlated with their degree of economic development. But it is worth wondering why economic underdevelopment is consistent with urban growth but not with city gl…
Induced Dipoles and Possible Modulation of Wireless Effects in Implanted Electrodes. Effects of Implanting Insulated Electrodes on an Animal Test to …
2021
There is evidence that Deep Brain Stimulation (DBS) produces health benefits in patients even before initiating stimulation. Furthermore, DBS electrode insertion in rat infralimbic cortex (ILC) provokes antidepressant-like effects before stimulation, due to local inflammation and astrogliosis. Consequently, a significant effect of implanting electrodes is suspected. External fields, similar in magnitude to the brain’s endogenous fields, induce electric dipoles in conducting materials, in turn influencing neural cell growth through wireless effects. To elucidate if such dipoles influence depressive-like behavior, without external stimulation, the comparative effect of conducting and insulate…
Calculation of size‐intensive transition moments from the coupled cluster singles and doubles linear response function
1994
Coupled cluster singles and doubles linear response (CCLR) calculations have been carried out for excitation energies and dipole transition strengths for the lowest excitations in LiH, CH+, and C4and the results compared with the results from a CI-like approach to equation of motion coupled cluster (EOMCC). The transition strengths are similar in the two approaches for single molecule calculations on small systems. However, the CCLR approach gives size-intensive dipole transition strengths, while title EOMCC formalism does not. Thus, EOMCC calculations can give unphysically dipole transition strengths, e.g., in EOMCC calculations on a sequence of noninteracting LiH systems we obtained a neg…
Search for magnetic monopoles with the MoEDAL prototype trapping detector in 8 TeV proton-proton collisions at the LHC
2016
The MoEDAL experiment is designed to search for magnetic monopoles and other highly-ionising particles produced in high-energy collisions at the LHC. The largely passive MoEDAL detector, deployed at Interaction Point 8 on the LHC ring, relies on two dedicated direct detection techniques. The first technique is based on stacks of nuclear-track detectors with surface area $\sim$18 m$^2$, sensitive to particle ionisation exceeding a high threshold. These detectors are analysed offline by optical scanning microscopes. The second technique is based on the trapping of charged particles in an array of roughly 800 kg of aluminium samples. These samples are monitored offline for the presence of trap…
Search for ultrarelativistic magnetic monopoles with the Pierre Auger Observatory
2016
We present a search for ultra-relativistic magnetic monopoles with the Pierre Auger Observatory. Such particles, possibly a relic of phase transitions in the early universe, would deposit a large amount of energy along their path through the atmosphere, comparable to that of ultrahigh-energy cosmic rays (UHECRs). The air shower profile of a magnetic monopole can be effectively distinguished by the fluorescence detector from that of standard UHECRs. No candidate was found in the data collected between 2004 and 2012, with an expected background of less than 0.1 event from UHECRs. The corresponding 90% confidence level (C.L.) upper limits on the flux of ultra-relativistic magnetic monopoles ra…
Search for relativistic magnetic monopoles with the ANTARES neutrino telescope
2012
Magnetic monopoles are predicted in various unified gauge models and could be produced at intermediate mass scales. Their detection in a neutrino telescope is facilitated by the large amount of light emitted compared to that from muons. This paper reports on a search for upgoing relativistic magnetic monopoles with the ANTARES neutrino telescope using a data set of 116 days of live time taken from December 2007 to December 2008. The one observed event is consistent with the expected atmospheric neutrino and muon background, leading to a 90% C.L. upper limit on the monopole flux between 1.3 ¿ 10¿17 and 8.9 ¿ 10¿17 cm¿2 s¿1 sr¿1 for monopoles with velocity ß ¿ 0.625.
Dwie drogi ze Wschodu na Zachód. Szkic biograficzny do historii polskich losów XIX i XX wieku
2020
The article was inspired by the biography of Zofia Kossak-Szczucka. The rich life of Zofia Kossak was full of extraordinary situations and twists and turns, but above all, her life was characterized by a constant journey. The road from one end of Europe – Ukraine, to the other – the British Isles. Her story became a pretext for presenting the path that two other Poles traveled from the eastern ends of Europe towards its heart and western borders. The first of them was known, although widely, but only from one chapter of the biography – Gabriel Narutowicz. An extremely interesting figure, who came to Switzerland from Lithuania for health reasons in the mid-1880s. He has found his new home in…
