16 Agro-hydrological models are considered an economic and simple tool to quantify crop water 17 requirements. In the last two decades, agro-hydrological physically based models have been 18 developed to simulate mass and energy exchange processes in the soil-plant-atmosphere 19 system. Although very reliable, due to the high number of required variables, simplified 20 models have been proposed...

A highly flexible porous ionic membrane (PIM) is fabricated from a polyvinyl alcohol/KOH polymer gel electrolyte, showing well-defined 3D porous structure. The conductance of the PIM changes more than 70 times as the relative humidity (RH) increases from 10.89% to 81.75% with fast and reversible response at room temperature. In addition, the PIM-based sensor is insensitive to temperature (0-95 ...

Water activities (potentials) in plant materials were measured over the range from free water to oven dryness with a Spanner thermocouple psychrometer. In a two-step procedure, water was first condensed on the thermocouple junction for several minutes. The sample was then inserted under the wet thermocouple and the maximum psychrometric cooling was measured in about 10 seconds. Calibration was ...

In this article, we study on the effect of different congregated granularities of microencapsulated n-octadecane on polyurethane foamed system, and the making of the polyurethane foams with high contents of microencapsulated n-octadecane. The results show that, when relative low granularities of microencapsulated phase change materials (MicroPCMs) are used as additives, the remnant water and fo...

the objective of this research was to investigate the effects of deficit irrigation on physiological and agronomic terms of eggplant to maximize the water use efficiency (wue) without affecting the final yield and fruit quality parameters under arid environment. therefore, two field experiments were conducted at two different sites: ghor al-safi, jordan valley and sail al-karak, karak valley, ka...

This paper reports the unexpectedly strong effect of 4 wt% additional sorbed water on the electrical and dielectric properties (50 Hze2 MHz) of graphite oxide (GO) containing 18 wt% sorbed water. Water contents of 18 and 22 wt% (designated GO18 and GO22, respectively) are compared, with the former obtained by heating at 60 C (3 h) immediately before testing. The additional water increases the c...

  Water deficit can be considered as one of the most important abiotic factors limiting plant function, which has also adverse affects on growth and production of medicinal plants. In this research, in order to evaluate the effects of water deficit stress on of Artemisia dracunculus plant, a completely randomized design with three replications was performed in greenhouse conditions. The ex...

The effects of water availability during incubation on the water contents of neonatal snapping turtles at hatching were examined, along with the influence of hatchling water content on desiccation tolerance and terrestrial locomotor performance. The water contents of hatchlings from eggs incubated on wet substrates were both absolutely and proportionally greater than were those of hatchlings fr...
