The aim of this paper is to analyze the potential of X-band SAR measurements (COSMO-SkyMed and TerraSAR-X) made over bare soils for the estimation of soil moisture and surface geometry parameters at a semi-arid site in Tunisia (North Africa). Radar signals acquired with different configurations (HH and VV polarizations, incidence angles of 26° and 36°) are statistically compared with ground mea...

We have synthesized a new benzomorphan derivative, 2R-[2alpha,3(S*), 6alpha]-1,2,3,4,5,6-hexahydro-6,11, 11-trimethyl-3-[2-(phenylmethoxy)propyl]-2, 6-methano-3-benzazocin-10-ol hydrochloride (BIII 890 CL), which displaced [(3)H]batrachotoxinin A-20alpha-benzoate from neurotoxin receptor site 2 of the Na(+) channel in rat brain synaptosomes (IC(50) = 49 nM), but exhibited only low affinity for ...

This report addresses computer support of complex cooperative work involving many actors. These actors might be distributed in time and space while collaborating. It is discussed which aspects of the coordination of cooperative work it would be relevant to consider supported by means of computer-based systems. A conceptual framework for analyzing and modeling the basic mechanisms used when mutu...

to assessment alfalfa cultivars research project this research has been fulfilled in 2011 at khouzestan agricultural and natural resource research center in southwest of ahwaz in khouzestan province (iran) by position 31º20′ n, 48º40′ e. at first section for evaluation wet forage yield cultivars such as “baghdadi”, “mesasersa”, “yazdi”, “bami”, “nikshahri”, “synthetic” (main factor) and two cut...

Background Cutaneous Leishmaniasis (CL) which is prevalent in all continents and is classified by the WHO as one of the neglected tropical diseases, existed in the past also, and discovered ancient works confirm this issue. The lack of adaptation of diseases between Persian Medicine (PM) and Modern medicine, led to no usage of effective therapeutic experiences of prior physicians. Objective T...

Quantifying surface water/ground water exchanges has become an important component of water resources management because of the increase in the conjunctive use of water. Reducing uncertainty in models used to select an optimal operation management alternative requires proper identification of the spatial and temporal variations in physical parameters such as the hydraulic conductivity of the st...
