“If thou go on the left hand, thou shalt in this way be soon essayed.”Words on the Cross to Sir Galahad, The Holy Grail, by Thomas Malory, Chapter XIIWords on the Cross to Sir Galahad,The Holy Grail, by Thomas Malory, Chapter XIIThough left and right are fundamental terms of our social and political vocabulary, perhaps indeed the ultimate dividing concepts of ways of life on the earth today, their meaning seems to be as obscure as their application is ubiquitous.

The article examines the interpretation of the Scripture in Byzantine hymnography during the Great Lent. Some notable recent contributions focus on Andrew of Crete’s and Romanos the Melodist’s compositions, illustrating the hymnographic way of understanding the Scriptures. The author of this study presents a selection of stanzas from hymns of the Triodion that refer to the trees of Paradise. Hymnography perceives the trees in Genesis 2–3 in direct connection with the cross. Only rarely is the tree of life a metaphor for Jesus, as the shadow of the tree of the cross is seldom a metaphor for protection. Another interesting aspect in relation to hymnography is the fact that it represents a type of intertextual exegesis of biblical texts. Hymnographers interpret passages from Genesis by using texts from Psalms, Prophets and especially from the New Testament, combining images and biblical texts in the depiction of liturgical moments.Contribution: Compared with previous research, this article discusses some rare hymnographic interpretations (shadow of the cross; cross in the middle of the earth). The analysis accentuates that the hymnic approach to the Scripture is a form of intertextual exegesis.


The main perturbations of a satellite orbit near the earth are those caused by the earth’s oblateness and the atmosphere. Fortunately these two sources produce perturbations of quite different types, and as a first approximation they can be treated separately, though the cross-couplings would have to be evaluated in a thorough analysis of the subject. There are other perturbations to the orbit, caused by the attractions of the sun, moon and planets, by relativity effects, by the fact that the earth is not symmetrical about its axis and by electromagnetic effects; but these perturbations are expected to be small and will not be discussed here.

Abstract. Terrestrial ecliptic dayside observations of the exospheric Lyman-α column intensity between 3–15 Earth radii (Re) by UVIS/HDAC at CASSINI have been analysed to derive the neutral exospheric H-density profile at the Earth's ecliptic dayside in this radial range. The data were measured during CASSINIS's swing by manoeuvre at the Earth on 18 August 1999 and are published by (Werner et al., 2004). In this study the dayside HDAC Lyman-α observations published by (Werner et al., 2004) are compared to calculated Lyman-α intensities based on the 3D H-density model derived from TWINS Lyman-α observations between 2008–2010 (Zoennchen et al., 2015). It was found, that both Lyman-α profiles show a very similar radial dependence in particular between 3–8 Re. Between 3.0–5.5 Re impact distance Lyman-α observations of both TWINS and UVIS/HDAC are existing at the ecliptic dayside. In this overlapping region the cross-calibration of the HDAC profile against the calculated TWINS profile was done, assuming, that the exosphere there was similar for both due to comparable space weather conditions. As result of the cross-calibration the conversion factor between counts/s and Rayleigh fc = 3.285 [counts/s/R] is determined for these HDAC observations. Using this factor the radial H-density profile for the Earths ecliptic dayside was derived from the UVIS/HDAC observations, which constrained the neutral H-density there at 10 Re to a value of 35 cm−3. Furthermore, a faster radial H-density decrease was found at distances above 8 Re (≈ r−3) compared to the lower distances 3–7 Re (≈ r−2.37). This increased loss of neutral H above 8 Re might indicate a higher rate of H ionization in the vicinity of the magnetopause at 9–11 Re (near sub solar point) and beyond, because of increasing charge exchange interactions of exospheric H atoms with solar wind ions outside the magnetosphere.

Neutrino can carry information from places that cannot be reached by the usual detection mechanism because it has a very weak interaction with matter. This can be utilized to study the heat flow process inside the earth by using information carried by geoneutrino (electron antineutrino). In this sense, it is important to know the characteristics of neutrino interaction with materials. In this study, the cross-section calculation of the electron antineutrino interaction with Ar-40 and Kr-84 was carried out using computational methods with the help of GENIE software. In the energy range of 0-10 MeV, the dominant interaction between the two materials is the interaction of QES NC and MEC types with an energy threshold of 5,09 MeV. Both Ar-40 and Kr-84 cannot be used as a scintillator material for geoneutrino detection because in the energy range 0-4,4 MeV the cross-sectional value of the CC interaction  is 0.

Abstract Comet disintegration proceeds both through sublimation and discrete splitting events. The cross-sectional area of material ejected by a comet may, within days, become many times greater than that of the Earth, making encounters with such debris much more likely than collisions with the nucleus itself. The hierarchic fragmentation and sublimation of a large comet in a short period orbit may yield many hundreds of such short-lived clusters. We model this evolution with a view to assessing the probability of an encounter which might have significant terrestrial effects, through atmospheric dusting or multiple impacts. Such an encounter may have contributed to the large animal extinctions and sudden climatic cooling of 12,900 years ago, and the near-simultaneous collapse of civilisations around 2350 BC.

Interest in the legal system of Israel is enhanced by the circumstances in which the new State came into being.The circumstances of place are peculiar, in that the territory of Israel is situated at the cross-roads of two continents and at the very focus of movements of upheaval by which they are both so deeply stirred.No less unusual are the circumstances of time. The proclamation of independence, for all its novelty, was not in the nature of a birth certificate, but rather of an official record of resurrection witnessed after a hiatus of close on two thousand years. No other people, so it seems, better demonstrates the adage that a nation's history is reflected in its institutions. Driven into exile and scattered to every corner of the earth for so many generations, it is now retrieving its identity in a supreme effort of reunion in its never-forgotten home-land. In the meantime, the fund of experience accumulated during the great dispersion has left its mark on the individuality of every immigrant, so that in many respects the mental attitude of the population is as variegated as the rainbow.

This chapter analyzes the Scriptures in several hymns prescribed for Good Friday, whose central theme is Jesus’s suffering as prophesied by Isaiah in the Servant of the Lord songs, where the Messiah is portrayed as a “lamb led to the slaughter” (Isa 53:7; cf. Jer 11:19). Mary, depicted as a “distraught ewe,” participates in her son’s suffering. In the hymnographers’ view, “circling dogs” borrowed from Ps 22:16 (21:17) might be read as a hint at Jesus nailed on a wooden pole with his enemies circling the cross like roaming dogs. The central hymn, “The one who hanged the earth in the waters is today hanged on a tree,” likens the earth hanging within the primordial waters (Gen 1:2) to the one hanging on the cross and wrestling with the evil powers lurking in those waters.

The last decade has seen a growing acceptance of the magnetometric resistivity (MMR) method as a viable exploration technique in various geologic environments. Until recently, MMR exploration was carried out with both current electrodes and recording magnetometer located on the surface of the Earth. Significant improvements in anomaly amplitude can be achieved by lowering the recording magnetometer inside a drill hole. In contrast, the lowering of current electrodes beneath the surface does not always improve surface MMR responses. The advantages of locating the magnetic detector in a drill hole are illustrated numerically, anomaly calculations being carried out with a novel yet simple integral equation technique for a plate‐like body. The practicality of the cross‐hole MMR technique is demonstrated with a successful case history. Massive sulfide mineralization is mapped at a depth exceeding 500 m.
