Water resources are one of the limiting factors of regional development around the Eastern and Southern Mediterranean. Scarcity and conflict, but also considerable uncertainty, inter-annual variability, and simple lack of reliable data characterize the problems of water resource management in many countries and river basins. Within the EU sponsored international RTD project OPTIMA a water resou...

oceanographic images obtained from environmental satellites by a wide range of sensors allow characterizing natural phenomena through different physical measurements. for instance sea surface temperature (sst) images, altimetry data and ocean color data can be used for characterizing currents and vortex structures in the ocean. the purpose of this thesis is to derive a relatively complete frame...

This paper presents a novel framework to extend the dynamic range of images called Unbounded High Dynamic Range (UHDR) photography with a modulo camera. A modulo camera could theoretically take unbounded radiance levels by keeping only the least significant bits. We show that with limited bit depth, very high radiance levels can be recovered from a single modulus image with our newly proposed u...

Partial least squares modeling as a powerful multivariate statistical tool was applied tothe simultaneous spectrophotometric determination of silicate and phosphate in aqueoussolutions. The concentration range for silicate and phosphate were 0.02-0.6 and 0.4-3 μg ml-1,respectively. The experimental calibration set was composed with 30 sample solutions using amixture design for two component mix...

Sea water samples were collected from 32 stations in the southern part of the Persian Gulf and the Gulf of Oman during winter of 1987. Surface water of the Persian Gulf exhibited wide range and higher values of salinity (37.15-43.95, mean 40.02%) compared with lower values and narrow range (36.58-36.95, mean 36.74%) in the Gulf of Oman. Surface salinity did not reflect any significant relations...

Stomata of corn (Zea mays L.) and sorghum (Sorghum bicolor L.) responded to changes in leaf water potential during the vegetative growth phase. During reproductive growth, leaf resistances were minimal and stomata were no longer sensitive to bulk leaf water status even when leaf water potentials approached -27 bars. Stomata of corn, cotton (Gossypium hirsutum L.), and sorghum appear to respond ...

Consensus is growing that agriculture is vulnerable to climate change and adaptation responses are necessary to minimize impacts. Nonetheless, the diversity of potential impacts, agro-ecological contexts and regional capacity for change make understanding adaptation behaviors challenging and ensure that climate change adaptation will not be the same across all contexts. Considering this heterog...
