Observations of Plasma Blob Ejection from a Quiescent Prominence by Hinode SOT

We report findings from 0.2" resolution observations of the 2007 October 03 quiescent prominence observed with the Solar Optical Telescope on the Hinode satellite. The observations show clear ejections from the top of the quiescent prominence of plasma blobs. The ejections, originating from the top of rising prominence threads, are impulsively accelerated to Alfvenic velocities and then undergo ballistic motion. The ejections have a characteristic size between ~ 1000 - 2000 km. These characteristics are similar to downwardly propagating knots (typical size ~ 700 km) that have been observed in prominence threads, we suggest that the plasma blob ejections could be the upward moving counterpart to the downwardly propagating knots. We discuss the tearing instability as a possible mechanism to explain the ejections.Comment: 9 Pages, 4 Figures, Accepted for publication in PASJ letter

The Syro-Ephraimite War and its Implications

The latter half of the eighth century B.C.E. in the Near East was a period of Assyrian resurgence and expansion to the west under the powerful king， Tiglath-Pileser III． ln response to this threat， Rezin， king of Aram， and Pekah， king of Israel， formed an anti-Assyrian coalition and attempted to persuade Ahaz of Judah to participate． After the Ahaz‘ rejection of this offer， Rezin and Pekah advanced against Judah and besieged Jerusalem， but had to withdraw because of the advancing Assyrian army， which took advantage of the opportunity to crash the coalition． This， so-called Syro-Ephraimite War， cannot be fully understood without consideration of its background， some of its problems， and its consequences

Rehoboam and His Fortified Cities

This paper surveys the list of Rehoboam\u27s fortified cities from the perspective of historiography and archaeology. The list to be dated from the time of Rehoboam and after the Egyptian invasion suggests the necessity of a chain of defense in the territory. A buffer zone of Benjamites explains the absence of the defense in the northern front. Gath in the list must be Moresheth-gath. Beth-zur was undefinable while Lachish had a small palace-like fortress at the time of Rehoboam, making the main settlement "fortified" to some extent

Burial Customs during Chalcolithic Palestine

This paper examines Chalcolithic burial customs in the four regions of Palestine. Tell ‘Adeimeh produced cist tombs in the Jordan Valley. The coastal plain caves contained ossuaries in the form of rectangular boxes decorated houses, and stone jars. Although the concentration of burials in the coastal plain led some archaeologists believe that Beersheba pastoralists used these caves during seasonal migration, there is no evidence for long-distance seasonal migration during the Chalcolithic. Nawamis in the Sinai were used by Sinai pastoralists as their tombs

Evaluating Competing Hypotheses with Bayes’ Theorem: Qumran as a Case Study

This article seeks to provide a new approach to the classic problem of determining the function of the community in Qumran. It considers three hypotheses concerning the function of the community at Qumran, and attempts to assign a probability to each using a Bayes\u27 theorem calculation in four steps: (1) Establish and list available data related to the hypotheses. (2) Numerically assess the data to establish data probabilities. (3) Establish prior probabilities. (4) Calculate posterior probabilities with Bayes\u27 theorem. The results of this calculation indicate a 36% probability that Qumran was an Essene community; 21% probability that Qumran was a military post; and 43% probability that Qumran was a commercial post

This article reviews the the theory behind research design, its background, its influence, and the limitations and future prospects. Developing research designs is based on General Systems Theory in which culture is a system composed of subsystems. The necessity to make explicit what we are trying to learn has had significant impact as shown in the projects discussed. Although General Systems Theory has limitations, systems thinking made a major contribution to our understanding of the necessity to build research designs

The Neo-Assyrian Empire: Its Military and Political Policies against Ancient Palestine

Discussing the neo-Assyrian policies against ancient Palestine, this paper deals with various aspects: the coalition against Shalmaneser III, the motivation for the Assyrian military campaigns in the ninth century B.C.E., Assyrian policy change under Tiglath-pileser III, Tiglath-pileser III\u27s campaign against Damascus and Samaria in 733-732 B.C.E., Assyrian rule over Philistia and Judah, mass deportation and its objectives. Sennacherib\u27s campaign in Palestine is still open to discussion. We also overview Sennacherib \u27s expedition to Philistia and Judah including the conquest of Lachish. In the decline of the Assyrian power, ancient Palestine again gained its independence

Qumran: What was the Nature of the Settlement?

To Dead Sea Scrolls――the fascinating manuscripts of the Hebrew Bible, its commentaries,and sectarian doctrines――were found in the caves near Qumran. The site, overlooking the Dead Sea,had a settlement that has been the focal point of controversy. What was the function(s) of the settlement? Various opinions have been proposed for this question. De Vaux (1973), the excavator of Qumran, thinks that the site was an isolated religious community of the Essenes. A military post,or fortress was suggested by Golb (1994). Crown & Cansdale favor the idea of a commercial entrepot (1994). ln this paper, several discussions are presented in order to determine which function(s) the settlement had. First, we attempt to define the Essenes to test the feasibility of Qumran――Essene connection; second, provided that the scrolls came from the settlement, we will review the question of who wrote the Dead Sea Scrolls; third, we will discuss the evidence of the archaeological excavation to examine whether that evidence supports any of the three functions
