40 A global coupled climate model representative of the current generation of models is 41 shown to simulate most first order aspects of El Niño events, their teleconnections over 42 North America, and the associated observed patterns of extremes in present-day climate. 43 Future El Niño teleconnection patterns over the U.S. are projected to shift eastward and 44 northward due in part to the di...

In early May of 1998 we saw the sea surface temperature signature of one of the strongest El Niños on record decay within a span of several weeks. At 125W the SST dropped over 5 oC in 17 days. What caused this abrupt end to the 1997-1998 El Niño? It is my goal to attempt to answer this question, at least in part, through the investigation of TAO mooring data including wind velocity, ocean SST, ...

This study was carried out on saline soils of Sahl El-Houssinia, El-Sharkia Governorate to evaluate three different water sources as a leaching and irrigation water in these soils and their use effect on some trace elements accumulation in the different soil layers. The using water sources were Bahr El-Bakar drain, Bahr Hadoos drain and El-Salam canal. These sources were used in the leaching th...

Article history: Received 1 June 2016 Received in revised form 29 November 2016 Accepted 8 December 2016 Available online xxxx Bronze production during the Iron Age of the Iberian Peninsula is characterised by the use of a relatively simple technology, based on crucible-furnaces. In an area rich in mineral resources, bronze was produced on a small scale and within settlements, to be used for ri...

F. Mora, S. Perret, C.A. Scapim, and E. Arnhold. 2010. Genetic parameters for growth and survival in Acacia saligna shrubs. Cien. Inv. Agr. 37(2):5-14. Acacia species have valuable agronomic characteristics, such as the tolerance to unfavorable environmental conditions. In this study, genetic parameters and selection response in Acacia saligna shrubs were investigated in two arid environments o...

Determination of the soil coverage by crop residues after ploughing is a fundamental element of Conservation Agriculture. This paper presents the application of genetic algorithms employed during the fine tuning of the segmentation process of a digital image with the aim of automatically quantifying the residue coverage. In other words, the objective is to achieve a segmentation that would perm...
