High Temperature Aquifer Thermal Energy Storage (HT-ATES) systems can be implemented to store geothermal energy, residual industrial heat and solar heat. Due to the large temperature differences between the injection fluid and ambient groundwater, buoyancy flow occurs, which causes heat losses which in turn results in poor efficiency of such systems. The heat losses can be reduced by applying d...

Eels colonize either marine, estuarine or freshwater habitats, with marine and estuarine eels tending to grow faster than freshwater eels. The reasons for these divergent migratory tactics and growth trajectories remain poorly understood. In order to investigate the role of salinity preferences of glass eels in the control of habitat selection and growth plasticity, we sorted different continge...

Salinity reduces substrate water potential, thereby restricting water and nutrient uptake by plants; salinity may also cause ionic imbalance and toxicity. Because substrate salinity fluctuates through the growing season, a plant may be exposed to different salinity levels, at various stages of development, with potentially significant consequences on population dynamics. Here, we present the re...

A new estuarine filamentous heterocystous cyanobacterium was isolated from intertidal sediment of the Lagoa dos Patos estuary (Brazil). The isolate may represent a new genus related to Cylindrospermopsis. While the latter is planktonic, contains gas vesicles, and is toxic, the newly isolated strain is benthic and does not contain gas vesicles. It is not known whether the new strain is toxic. It...

to understand the effects of salinity stress on four different growth stages of sorghum, a greenhouse experiment with 10 treatments, considering all possible combinations of salinity stress and salt- free periods was carried out. the four growth stages for stress application included: emergence until growing point differentiation, growing point differentiation until half bloom, half bloom until...

resulted in highest leaf N content. Only one-half the amount of controlled release N was used on plants in the combination treatment as was used on plants where controlled release N was the only fertilization. Soil tests did not show significant variation between treatments with regard to pH, salinity, P, K, Ca and Mg content. The pH ranged from 6.5 to 7.4 and the salinity was not high enough t...

the effects of salinity and supplied calcium chloride on growth and leaf ions concentration of tomato (lycopersicon esculentum l.) were investigated in gorgan, iran. a factorial experiment was conducted based on rcbd with four nacl levels (0, 50, 100, and 150 mm) and four cacl2 levels (0, 100, 200 and 300 mg l-1). data of growth, yield and leaf’s ca, k, and na content were subjected to analyze ...

the development of seminal and lateral root system plays a major role in plant access to water and nutrients under abiotic stress, especially salinity. in order to understand the relation between root growth responsesand shoot physiological indices oftwo bread wheat cultivars contrasting in salt tolerance (kavir and shiraz), a greenhouse experiment was conducted with two salinity levels (0 and ...
