Soil parent materials and the pottery of Roman Galilee: A comparative study     

Moshe Wieder  David Adan‐Bayewitz 《Geoarchaeology》2002,17(4):393-415

The paper presents a comparative micromorphological analysis of the range of soil materials used to make the pottery of the hilly Galilee during the Roman period, and the ceramic products made from these materials. The four soil units that served as raw material for most of the pottery made in this period and region are examined along with pottery derived from each of them. For each soil unit, the soil characteristics and processes are described, followed by a presentation of the micromorphological characteristics of the soil material and those of the pottery made from that material. The contribution of the aeolian dust component to the soil materials is discussed as well as the identification of the tempering materials (nonplastics or other soil materials) added to the pottery paste. The study demonstrates the close correlation in microfabric between the pottery and original soil materials, sheds light on the raw material selection and modification practices of the potters of Roman Galilee, and has significant implications for provenance studies, using chemical analysis, on the pottery of this period and region. © 2002 Wiley Periodicals, Inc.  相似文献

Holocene yardangs in volcanic terrains in the southern Andes,Argentina   总被引：2，自引：0，他引：2  

Moshe Inbar  Corina Risso 《地球表面变化过程与地形》2001,26(6):657-666

Yardangs of different sizes were developed in the Payun Matru Volcanic Field, a semiarid area east of the southern Andes mountains. Yardangs from volcanic terrains have not been described previously from Earth, although studies from Mars interpreted linear ridges found by Mariner and Viking images as yardangs. The Payun Matru Volcanic Field is an extensive plateau at 2000 m a.s.l. covered by basaltic lava and ignimbrite flows. Strong westerly winds affect the extensive plateau. Micro‐ and mesoyardangs are formed on the ignimbrite rock blanket, and macroforms or megayardangs, several kilometres in length, are developed in the basaltic lava flows as long parallel troughs. They all have a distinctive 320° azimuth, which is the prevailing wind direction. No yardang features are noted in the more recent lava flows, younger than 1000 years, indicating that their formation needed a longer time or they developed in earlier periods with stronger winds. The yardang development is explained by the strong unidirectional winds, the poor vegetational cover due to the aridity of the region, the available quartz sand and volcanic ash particles as abrasive agents, and the volcanic lithology texture and flow structure.

The Macrobenthic Associations of Haifa Bay, Mediterranean Coast of Israel     

Moshe  Tom Bella  Galil 《Marine Ecology》1991,12(1):75-86

Abstract. Species composition, distribution, and relative abundance of macrobenthic fauna were examined at Haifa Bay on the Mediterranean coast of Israel. Benthic samples were taken over a two-year period at twenty sites ranging in depth from 10-80m. The relevant sedimentological features of the area are discussed. Classification of the faunal data produced a hierarchical grouping of sites and species, displayed as dendrograms. Ten sample groups and eleven species associations are identified. The obsérved qualitative differences arc related to the prevailing environmental conditions in the area. A unique species association, related to cobble-sized bioherms, is described. Massive penetration by four benthic species of Indo-Pacific origin, Lessepsian migrants, is reported.  相似文献

Image enhancement by multi‐parameter characterization of common image gathers     

Moshe Reshef 《Geophysical Prospecting》2014,62(6):1453-1467

We present an innovative approach for seismic image enhancement using multi‐parameter angle‐domain characterization of common image gathers. A special subsurface angle‐domain imaging system is used to generate the multi‐parameter common image gathers in a summation‐free image space. The imaged data associated with each common image gathers depth point contain direction‐dependent opening‐angle image contributions from all the available incident and scattered wave‐pairs at this point. Each direction‐dependent opening‐angle data can be differently weighted according to its coherency measure. Once the optimal migration velocity is used, it is assumed that in the actual specular direction, the coherency measure (semblance) along reflection events, from all available opening angles and opening azimuths, is larger than that along non‐specular directions. The computed direction‐dependent semblance attribute is designed to operate as an imaging filter which enhances specular migration contributions and suppresses all others in the final migration image. The ability to analyse the structural properties of the image points by the multi‐parameter common image gather allows us to better handle cases of complicated wave propagation and to improve the image quality at poorly illuminated regions or near complex structures. The proposed method and some of its practical benefits are demonstrated through detailed analysis of synthetic and real data examples.  相似文献   

Trends in CO2 emissions in Israel—an international perspective     

Moshe Yanai  Jean Koch  Uri Dayan 《Climatic change》2010,101(3-4):555-563

As a Party to the United Nations Framework Convention on Climate Change, Israel conducts a periodical inventory of greenhouse gases emissions. These data allowed the generation of time series of CO₂ emissions per capita and per GDP for the period 1990–2004. It was found that CO₂ emissions per capita increased dramatically from 1990 to 2000, reflecting the rapid economic growth that was initiated by the massive immigration wave at the beginning of the nineties. These emissions remained stable between 2000 and 2004, reflecting the economic stagnation caused by the uprising in the Palestinian Territories, as well as stagnation in the global economy. CO₂ emissions per GDP (CO₂ intensity) remained stable along the whole reviewed period. This stability can be explained by a shift in electricity consumption from the industrial sector towards the commercial and the residential sectors, corresponding to an increase in the standard of living in the same period. A comparison was held with countries considered as developed for many years represented by the five largest economies (G-5) and recently developed countries (RDCs). Although Israel exhibits emission levels within the range of the G-5 countries, it does not fit the patterns demonstrated by these countries. Trends observed in Israel resemble these observed in other RDCs, such as Spain or Greece, confirming the classification of Israel in this category.  相似文献

A Thin Ring Model for the Oh Megamaser in Iiizw35     

Rodrigo Parra  John Conway  Moshe Elitzur 《Astrophysics and Space Science》2005,295(1-2):325-330

We present a model for the OH megamaser emission in the starburst galaxy IIIZw35. The observed diffuse and compact OH maser components in this source are explained by a single phase of unsaturated clumpy gas distributed in a thin ring structure and amplifying background continuum. We emphasize the importance of clumpiness in the OH masing medium, an effect that has not been fully appreciated previously.The model explains why multiple bright spots are seen only at the ring tangents while smoother emission is found elsewhere. Both the observed velocity gradients and the line to continuum ratios around the ring enquire a geometry where most of the seed photons come from a continuum emission which lies outside the OH ring. To explain both the OH and continuum brightness, free-free absorbing gas is required along the ring axis to partially absorb the far side of the ring. It is proposed that the required geometry arises from an inwardly propagating ring of starburst activity.  相似文献
