Writing Palestine

From her immigration to Mandatory Palestine in 1933 until her death in 1950 American-born Dorothy Kahn Bar-Adon worked as a reporter for The Palestine Post (later The Jerusalem Post), while freelancing for periodicals in Palestine and abroad. Bar-Adon covered life in towns, kibbutzim and Arab communities of Mandatory Palestine during this period of World War, armed conflict between Arabs and Jews, immigration to Israel of Holocaust survivors. Close to 60 years after her death, this edited collection of Bar-Adon’s writing offers a vivid view both of daily life in the Jewish and Arab communities of pre-State Israel, and of the burning issues of the day

Molecular motions and phase transitions. NMR relaxation times studies of several lecithins

The spin-lattice relaxation time, T1, and the dipolar energy relaxation time, TD, were measured as a function of temperature. The materials studied were samples of anhydrous L-dipalmitoyl lecithin, DL-dipalmitoyl lecithin, L-dimyristoyl lecithin, DL-dimyristoyl lecithin and their monohydrates, and of anhydrous egg yolk lecithin. It is shown that TD is a much more sensitive parameter than T1 for the determination of the Chapman phase transition. Comparison between T1 and TD provides information about new types of slow molecular motions below and above the phase transition temperature. It is suggested that the relaxation mechanisms for T1 and TD in the gel phase are governed by segmental motion in the phospholipid molecule. A new metastable phase was detected in dimyristoyl lecithin monohydrates. This phase could only be detected from the dipolar energy relaxation times

New Radiocarbon Dates for the Reed Mat from the Cave of the Treasure, Israel

From the 17th International Radiocarbon Conference held in Jerusalem, Israel, June 18-23, 2000.Modern radiocarbon dates were procured for the Cave of the Treasure, Israel reed mat at the University of Arizona accelerator mass spectrometry (AMS) laboratory in late 1999 and early 2000. Three samples from various locations on the mat were dated. One of these samples was dated twice, and another was dated three times, yielding a total of six new radiocarbon dates on the mat. The new 14C dates overturn expectations of a late Chalcolithic, roughly 3500 BC, date for the origin of the mat. It is suggested that the mat may not have been of common use but may rather have been a religious heirloom with a history stretching back into the early Chalcolithic.The Radiocarbon archives are made available by Radiocarbon and the University of Arizona Libraries.

Dating a Chalcolithic Burial Cave in Peqi'in, Upper Galilee, Israel

From the 16th International Radiocarbon Conference held in Gronigen, Netherlands, June 16-20, 1997.In May 1995 an impressive karstic cave possessing dozens of burials dating to the main phase of the Chalcolithic Period (ca. 4500-3500 BCE) was discovered in Peqi'in in the high hills of Galilee in northern Israel. It was subsequently excavated over the course of the following months. The large amount of unique ceramic ossuaries and the variety of burial offerings shed light, for the first time, on this critical societal development period in a region where its remains have rarely been found. Although the major significance of the cave is as a mortuary center, it was also utilized in a domestic capacity some centuries previously, during the generally less familiar Early Chalcolithic Period. We present here the dating of 22 14C samples collected from these separate phases of cave use. Their interpretation should aid in understanding of the absolute dating of the Chalcolithic Period and its relation to the period preceding its inception.This material was digitized as part of a cooperative project between Radiocarbon and the University of Arizona Libraries.The Radiocarbon archives are made available by Radiocarbon and the University of Arizona Libraries.

Near East Chronology: Towards an Integrated 14

From the 17th International Radiocarbon Conference held in Jerusalem, Israel, June 18-23, 2000.Chronology is the backbone of all history, as the flow of time is identical in scholarly and scientific fields, even in the Near East. Radiocarbon dating can provide an essential and unifying chronological basis across disciplines, despite precision limitations. This issue presents exciting new 14C developments in archaeological and environmental contexts, ranging from Proto-Neolithic cultures to historic earthquakes along the Dead Sea. Dark periods devoid of settlement in the deserts of the southern Levant seem to disappear with 14C dating. Significant new findings collectively indicate the need for major chronological revisions in the 4th and 3rd millennia BCE in Egypt and the Levant. The implications for the 2nd millennium BCE are not yet established, but the use of 14C dating in the Iron Age is finally beginning to focus on current controversies. The chronological way forward for Dynastic Egypt and the Levantine Bronze and Iron Ages is a multi-disciplinary approach based on detailed high-quality 14C series as a unifying time foundation to anchor archaeological, textual, and astronomical data.The Radiocarbon archives are made available by Radiocarbon and the University of Arizona Libraries.
