Biblical evidence from Obadiah and Psalm 137 for an Edomite treaty betrayal of Judah in the sixth century B.C.E.

Abstract: Focusing on Obadiah and Psalm 137, this article provides biblical evidence for an Edomite treaty betrayal of Judah during the Babylonian crisis ca. 588–586 B.C.E. After setting a context that includes the use of treaties in the ancient Near East to establish expectations for political relationships and the likelihood that Edom could operate as a political entity in the Judahite Negev during the Babylonian assault, this article demonstrates that Obadiah’s poetics include a density of inverted form and content (a reversal motif) pointing to treaty betrayal. Obadiah’s modifications of Jeremiah 49, a text with close thematic and terminological parallels, evidence an Edomite treaty betrayal of Judah. Moreover, the study shows that Obadiah is replete with treaty allusions. A study of Psalm 137 in comparison with Aramaic treaty texts from Sefire reveals that this difficult psalm also evidences a treaty betrayal by Edom and includes elements appropriate for treaty curses. The article closes with a discussion of piecemeal data from a few other biblical texts, a criticism of the view that Edom was innocent during the Babylonian crisis, and a suggestion that this treaty betrayal may have contributed to the production of some anti-Edom biblical material.

Combustion of CS₂/O₂ in a laminar mixing layer and processes in the CO chemical laser

The combustion of CS₂ and O₂ in a free burning laminar mixing layer at low pressure was investigated using emission spectroscopy. The temperature fields, CO vibrational distributions, and CO concentrations were measured. The data indicate that vibration ally excited CO was produced in the mixing layer flames, but that there were no vibrational population inversions. In comparison with the CS₂/O₂ premixed flames, the mixing layer flames favored greater production of COS and CO₂. Computer modeling was used to study the mechanisms responsible for the production of COS and CO₂, and to study how the branching chain mechanism responsible for production of CO affects the behavior of the mixing layer flame. The influences of the gas additives, N₂O, COS, and CNBr, were also investigated.

Assessment of siltation rate and sediment transport in Bombay harbour based on Cesium-137 distribution

Low level aqueous radioactive wastes from the nuclear complex at Trombay are discharged into the Bombay harbour. Of the 6 principal radionuclides comprising the discharge, cesium-137 is most predominantly taken up by silt from the sea water. Isoactivity contours show that activity levels just off the point of discharge, and further south to Pir Pau, were between 50 and 100 pCi/g. Activity in the main channel of the harbour remained below 10 pCi/g, while further north (below the Thane Creek bridge) it was around 20 pCi/g. Activity in the top 6 cm of a core off Trombay naval jetty was <5 pCi/g, reaching a maximum of 178 pCi/g at 14cm below the surface. Thereafter, it tapered off to 5 pCi/g down to a metre.

Sedimentation rates, nitrogen and phosphorus retentions in the largest urban Lake Donghu, China

Sediment core samples were collected in the largest urban Lake Donghu (Stations I and II) in China, and the activities of Pb-210, Ra-226 and Cs-137 were measured by gamma-ray spectrometry. The sedimentation rates, calculated by 210Pb constant rate of supply (CRS) model, ranged from 0.11 to 0.65 (average 0.39) cm(.)y(-1) at Station I, and from 0.21 to 0.78 (average 0.46) cm(.)y(-1) at Station II. Sedimentation rate calculated by Cs-137 as a time marker was 0.55 cm(.)y(-1) at Station II. Based on the average sedimentation rate, we obtained 769 and 147 t(.)y(-1) for nitrogen and phosphorus retentions in Lake Donghu sediments, respectively.

高抗冲聚苯硫醚（PPS）的研究；PC/PBA-cs-PMMA共混体系的研究

聚苯硫醚（PPS）是特种工程塑料中应用最广、价格最低的品种。但由于其耐冲击性差，限制了其做为结构材料的应用。本论文通过多种研究方法，研究了PPS抗冲击性差的根本原因和改善途径，从改变其聚集态结构入手，使韧性得到了很大改善，为高抗冲PPS的研制提供和积累了丰富了可靠的数据，其创新性成果体现在：提出了含刚性非晶相、可动（类液）非晶相和晶相的PPS三相模型并计算了各相的相对含量、测定了各相的密度；发现了PPS的冲击强度与其结晶度呈近似线性的关系。是十分有意义的基础性工作。用核壳乳液聚合物做为PC的增韧剂，有效地控制了共混物的形态结构、计算出了界面层厚度与界面张力，为制备具有综合性能的改性PC材料奠定了理论和实践基础。

ELECTRONIC-STRUCTURES OF THE ALKALI-CONTAINING BUCKMINSTERFULLERENES (A-DELTA-C60) (A=LI,NA,K,RB,CS) AND THE HALOGEN-CONTAINING BUCKMINSTERFULLERENES (H-DELTA-C60) (H=F,CL,BR,I)

The geometrical parameters and electronic structures of C60, (A partial derivative C60) (A = Li, Na, K, Rb, Cs) and (H partial derivative C60) (H = F, Cl, Br, I) have been calculated by the EHMO/ASED (atom superposition and electron delocalization) method. When putting a central atom into the C60 cage, the frontier and subfrontier orbitals of (A partial derivative C60) (A = Li, Na, K, Rb, Cs) and (H partial derivative C60) (H = F, Cl) relative to those of C60 undergo little change and thus, from the viewpoint of charge transfer, A (A = Li, Na, K, Rb, Cs) and H (H = F, Cl) are simply electron donors and acceptors for the C60 cage resPeCtively. Br is an electron acceptor but it does influence the frontier and subfrontier MOs for the C60 cage, and although there is no charge transfer between I and the C60 cage, the frontier and subfrontier MOs for the C60 cage are obviously influenced by I. The stabilities DELTAE(X) (DELTAE(X) = (E(X) + E(C60)) - E(x partial derivative C60)) follow the sequence I < Br < None < Cl < F < Li < Na < K < Rb < Cs while the cage radii r follow the inverse sequence. The stability order and the cage radii order have been explained by means of the (exp-6-1) potential.

用47 MeV/u 12C离子轰击133Cs靶,应用放射化学分离技术和离线γ射线谱学,得到碘同位素的产生截面。丰中子碘同位素的独立产生截面指数地依赖于Qgg值,而缺中子碘同位素的独立产生截面则偏离这一直线关系。这一事实可对在深部非弹转移过程中产生丰中子碘同位素予以解释。
