Mysteries of Osiris - performance or ritual?
No full textThe article is devoted to the question of ancient Egyptian mysteries of Osiris, god of death and renewable life. During this feast, priests were playing story about the anguish, death, and resurrection of the god. Author attempts to reconstruct course of the performance. Mysteries of Osiris are an unique phenomenon out of one significant reason: they’re ritual as well as performance. Author refers to actual discussion in theatre science about origins of the theatre. It shows that history of theatre can start earlier than in ancient Greece

OSIRIS-APEX: An OSIRIS-REx Extended Mission to Asteroid Apophis
No full textThe Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer (OSIRIS-REx) spacecraft mission characterized and collected a sample from asteroid (101955) Bennu. After the OSIRIS-REx Sample Return Capsule released to Earth’s surface in 2023 September, the spacecraft diverted into a new orbit that encounters asteroid (99942) Apophis in 2029, enabling a second mission with the same unique capabilities: OSIRIS-Apophis Explorer (APEX). On 2029 April 13, the 340 m diameter Apophis will draw within ∼32,000 km of Earth’s surface, less than 1/10 the lunar distance. Apophis will be the largest object to approach Earth this closely in recorded history. This rare planetary encounter will alter Apophis’s orbit, will subject it to tidal forces that change its spin state, and may seismically disturb its surface. APEX will distantly observe Apophis during the Earth encounter and capture its evolution in real time, revealing the consequences of an asteroid undergoing tidal disturbance by a major planet. Beginning in 2029 July, the spacecraft’s instrument suite will begin providing high-resolution data of this “stony” asteroid—advancing knowledge of these objects and their connection to meteorites. Near the mission’s end, APEX will use its thrusters to excavate regolith, a technique demonstrated at Bennu. Observations before, during, and after excavation will provide insight into the subsurface and material properties of stony asteroids. Furthermore, Apophis’s material and structure have critical implications for planetary defense. © 2023. The Author(s).

Horus' Eye and Osiris' Efflux [Elektronisk resurs] : The Egyptian Civilisation of Inundation ca. 3000-2000 BCE
No full textDeath and the life-giving waters of the Nile were intimately interwoven in ancient Egyptian religion. The principal objective of this study is to develop a synthetic perspective for enhancing the understanding of the religious roles water had in the rise and constitution of the Egyptian civilisation during the Early Dynastic Period and the Old Kingdom. The author employs an archaeological, inter-disciplinary and comparative ‘water perspective’ in which water not only forms the analytical framework, but also provides empirical data that allow for new questions to be addressed. Thus, the Nile itself is used as the primary point of departure to analyse how, why and when religious changes took place, with a particular emphasis on the development of the Osiris cult. Use is made of contemporary written sources, in particular the Pyramid Texts, but also other mortuary texts as well as flood records. The evolution of the Osiris cult is then analysed in relation to the development of the mortuary monuments; the mastabas in the First and the Second Dynasties and the emergence of the pyramids from the Third Dynasty. Hence, by comparing the different funerary monuments and practices with the emergence of the Osiris cult in relation to climatic changes and fluctuations in the Nile’s yearly inundation, Ancient Egyptian religion and the rise of the civilisation is analyzed according to a water perspective. It is noted that the Blue Nile was not blue, but red-brownish during the flood. When the flood started, the White Nile was not white, but green. The author argues that these fundamental characteristics of the Nile water formed the basis for the Osiris mythology. The red floodwaters in particular represented the blood of the slain Osiris.</p
Nota exegética a Plutarco, Isis y Osiris 351E
No full textIn this article, I deal with a short but complex sentence at the end of the first chapter of Plutarch’s Isis and Osiris. Plutarch there says that «the happiness of even the eternal life, which God has obtained as his portion, consists in the fact that the things that come to be do not, through knowledge, fail in advance» (351E). This obscure phrase implies, so I argue, that Plutarch’s providential God has a knowledge of particular contingencies and that this knowledge indeed contributes to his eternal blessedness without affecting His essence.En este artículo, me ocupo de una breve pero compleja frase al final del primer capítulo de la obra de Plutarco Isis y Osiris. Dice Plutarco que «la felicidad incluso de la vida eterna, que Dios ha obtenido como su porción, consiste en el hecho de que las cosas que llegan a ser no fracasan por adelantado gracias al conocimiento» (351E). Esta oscura frase implica, en mi opinión, que el Dios providencial de Plutarco tiene un conocimiento de las contingencias particulares y que este conocimiento contribuye efectivamente a su bienaventuranza eterna sin que ello afecte a Su esencia
Software and hardware development for the liquid scintillator detector OSIRIS of the JUNO experiment
No full textThe Jiagmen Underground Neutrino Observatory (JUNO) is a next-generation liquid scintillator (LS) neutrino experiment currently under construction near Kaiping, Southern China. The construction of JUNO will end in 2024. JUNO will accomplish its main goal with six years of data-taking: the determination of the neutrino mass ordering with a sensitivity of 3-4 . To achieve this goal, the LS used in JUNO must meet stringent requirements regarding its radiopurity. For validation of these requirements during the months-long filling of JUNO, the Online Scintillator Internal Radioactivity System (OSIRIS) monitors the LS radiopurity via Bi-Po / Bi-Po coincident decays in the respective decay chains of U and Th. In OSIRIS, German workgroups have a leading role. This thesis presents contributions to the development of both hardware and software for OSIRIS. The hardware-focused part of the thesis details the author's construction of an ultrapure-water-based cleaning facility at RWTH Aachen as well as the design of a holder structure for OSIRIS's photomultiplier tubes (PMTs). The cleaning facility was used successfully to prepare many German working groups' contributions prior to their shipment to China. The holder development was aided by simulations based on finite element analysis. Both holder design requirements and simulation results were confirmed in load tests of the holder structure, first at RWTH and later again on-site at JUNO in 2022. The holder as originally planned for the intelligent PMT system (iPMT) had to be adapted at JUNO to accommodate the Chinese Large PMT system (LPMT), because the iPMTs were found to be non-functional upon arrival at JUNO. During the on-site mission in 2022, also studies of airborne and surface dust levels within the OSIRIS detector were carried out by the author. The investigations proved that a) OSIRIS's air filtration unit maintained the required ISO-7 clean room environment and b) the accumulated dust on OSIRIS's central vessel was uncritical for the experiment's future. The measurements also showed a substantial decrease in surface particle counts after a subsequent detector cleaning. The commissioning of one of OSIRIS's calibration systems, the Automated Calibration System (ACU), was supervised by the author in 2023 as another part of the hardware-related work described here. The ACU contains a radioactive multi-gamma source (Cs/Zn/Co) and a 435 nm LED to perform calibrations of LPMT timing and charge as well as calibrations of detector energy and vertex reconstructions. A K-source serves as a standard candle during normal operation and is used to monitor the optical properties of the LS. During the ACU commissioning, the ACU hardware and software, the related safety mechanisms, and the positioning of the sources were evaluated. In the positioning calibrations, a precision of 4 mm was achieved, which is well below the sub-cm requirement of OSIRIS. Overall, the results of the commissioning successfully prepared the ACU for nominal operation in OSIRIS. The calibration of OSIRIS with the ACU was also the key aspect of the software-focused part of the thesis. The presented GEANT4-based energy calibration studies improved the analysis algorithms in terms of stability and speed, while also determining a minimal statistic of 30k events needed for each of the involved radioactive isotopes to reach required precision levels. The analyses of different source capsule designs validated their usability in OSIRIS and led to an approval for the calibration source production in late 2022. Also a first set of ACU calibration data, recorded with the LED of the ACU, was analysed by the author. The analysis focused on evaluating the overall detector performance and identified irregularities for PMTs close to the LED cable, promptly triggering investigations by the OSIRIS group. The analysis also confirmed both the principle of aligning the PMT timings and the expected detector behaviour for different illumination levels

Myth of Isis and Osiris ancienti sources and modern interpretation
No full textEgipatska mitologija je možda najočitiji primjer zrcaljenja geografskog i prostornog konteksta u kulturi i religiji, pa su se tako mitovi pojavili upravo u sredini u kojoj su vladale suprotnosti, što je Egipćane uvijek nanovo vraćalo na promišljanje o životu i smrti. Upravo iz tog razloga mnogi autori cesto počinju istraživanje o ovoj temi proučavanjem prirodnih uvjeta koji su mogli utjecati na određena vjerovanja. Bogovi i mitovi Egipta imaju neke sličnosti s mnogim mitologijama i kulturama, no isto tako posjeduju i neke posebnosti koje su karakteristične samo za podneblje na kojem su nastale. Mitovi su se, poput nekog bića, mijenjali, stvarali, na neki način i zaboravljali. Prema pojedinim autorima, egipatski religiozni sistem sadržavao je mnoštvo nivoa svijesti: tako je u isto vrijeme mogao postojati apstraktni, monoteistički i politeistički pristup. Sve ove činjenice potvrđuju da se radi o jednom zaista kompleksnom religijskom sustavu.Mythology is the first attempt of explaining of what is surrounding us, what is indistinct, what we are afraid of. However, as created, myths have also been changed. The Egyptian Myth of Isis and Osiris is one of the most known myths at all. Relying on the ancient sources and using their contemporary interpretation, the author is processing few possible interpretations of The Myth of Isis and Osiris, trying to align them within a context of the myth itself. Selected interpretations explain political - social aspect, anthropological cultural, psychological and philosophical - anthropological aspects. The result of these different interpretations of the myth is an attempt to explain one of the major cultures of the world. Considering that the same culture had a great influence on the rest of the world, the author provides an insight into the persistence of the myth today and how it is at least partially visible to us. Trying to maintain critical attitude, the author concludes that no matter how different contemporary interpretations are, there is an acknowledgment to the tendency for eternal between them, which in its essence this myth is
Effect of volcanic aerosol on stratospheric NO2 and N2O5 from 2002-2014 as measured by Odin-OSIRIS and Envisat-MIPAS
No full textFollowing the large volcanic eruptions of Pinatubo in 1991 and El Chichón in 1982, decreases in stratospheric NO2 associated with enhanced aerosol were observed. The Optical Spectrograph and Infrared Imaging Spectrometer (OSIRIS) measured the widespread enhancements of stratospheric aerosol following seven volcanic eruptions between 2002 and 2014, although the magnitudes of these eruptions were all much smaller than the Pinatubo and El Chichón eruptions. In order to isolate and quantify the relationship between volcanic aerosol and NO2, NO2 anomalies were calculated using measurements from OSIRIS and the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS). In the tropics, variability due to the quasi-biennial oscillation was subtracted from the time series. OSIRIS profile measurements indicate that the strongest anticorrelations between NO2 and volcanic aerosol extinction were for the 5km layer starting ∼ 3km above the climatological mean tropopause at the given latitude. OSIRIS stratospheric NO2 partial columns in this layer were found to be smaller than background NO2 levels during these aerosol enhancements by up to ∼ 60% with typical Pearson correlation coefficients of R ∼ -0. 7. MIPAS also observed decreases in NO2 partial columns during periods affected by volcanic aerosol, with percent differences of up to ∼ 25% relative to background levels. An even stronger anticorrelation was observed between OSIRIS aerosol optical depth and MIPAS N2O5 partial columns, with R ∼ -0. 9, although no link with MIPAS HNO3 was observed. The variation in OSIRIS NO2 with increasing aerosol was found to be consistent with simulations from a photochemical box model within the estimated model uncertainty.© Author(s) 2017. .This work was supported by the Natural Sciences and Engineering Research Council (Canada) and the Canadian Space Agency.
