Zodiac Calendars in the Dead Sea Scrolls and Their Reception: Ancient Astronomy and Astrology in Early Judaism

The traditional mathematical foundation of the Aramaic calendars within the lifeless Sea Scrolls is analysed during this research. Helen R. Jacobus re-examines an Aramaic zodiac calendar with a thunder divination textual content (4Q318) and the calendar from the Aramaic Astronomical ebook (4Q208 - 4Q209), all from Qumran. Jacobus demonstrates that 4Q318 is an ancestor of the Jewish calendar this day and that it is helping us to appreciate 4Q208 - 4Q209.

The overall effect of these reactions was estimated to have increased the porosity of some parts of the shale fill by up to 10%, with possibly significant implications for its geotechnical behavior (Fig. 8). , 1994; Pye and Mottershead, 1995). 8.

The limestone that had an oosparitic texture showed better resistance to decay than did the stone having an oomicritic texture, despite being exposed to higher pollution levels at its collection site in central London.

The rock has a high detrital matrix to cement ratio, the detrital component consisting mainly of sand- and silt-size quartz and feldspar fragments, with subsidiary mica.

Scale bar = 100 /x,m. 33 SEDIMENT GRAINS, WEATHERING, AND EARLY DIAGENETIC PHENOMENA of large amounts of ettringite is detrimental to the strength of the concrete because this calcium-alumino-sulfate mineral contains 31 water molecules in its structure and is prone to large volume changes. These water molecules cause expansion of the concrete and progressively reduce its strength. In extreme cases, concrete that has been severely affected by sulfate attack becomes crumbly and disintegrates altogether.
