over the past years, lake water levels have decreased considerably by various factors and the subsequent emergence of salt plain has brought disastrous consequences that need an essential action. therefore, this study aimed to investigate the effects of drying up and increasing lake water salt and landsat satellite images were used during different time periods in 9 years. to identify the new a...

Plastic pollution has universally known accumulated in all environment compartments and accelerating threat to the sustainability of earth. Field survey to examine the occurrence of microplastics in ancient sea water evaporation technology of ponds at Pallengu-Jeneponto, was conducted. From this sea salt producing ponds, samples of water, sediment and freshly harvested salts were collected. Six...

this study investigated intra-specific variation in the growth parameters and dry mat-ter partitioning of sugar beet cultivars at different levels of salinity (0, 50, 150, 250 and 350 mm nacl + cacl2 in 5:1 molar ratio) using four cvs, one british (madison) and three iranian cvs (7233-p12, 7233-p21 and 7233-p29). the plants were grown in a controlled greenhouse environment for about 18 weeks. a...

in this study some thermodynamic parameters including freezing point, boiling point and the vapor pressure of urmia lake salt water were investigated as some important environmentally monitored physicochemical properties of urmia lake. in this regard salt concentration is chiefly responsible for the modification of the thermodynamic properties of urmia lake water which affects its overall envir...

Since arginine vasopressin may play a role in mineralocorticoid hypertension, we examined the effects of deoxycorticosterone acetate (DOCA)-salt on vasopressin V1 and V2 receptor binding and their second messengers, inositol phosphate and adenylate cyclase, respectively, in liver and kidney to determine whether altered vasopressin receptor binding is pathogenetic in mineralocorticoid hypertensi...

The ultraviolet photolysis of CH(2)I(2) was studied in water and salt water solutions using photochemistry and picosecond time-resolved resonance Raman spectroscopy. Photolysis in both types of environments produces mainly CH(2)(OH)(2) and HI products. However, photolysis of CH(2)I(2) in salt water leads to the formation of different products/intermediates (CH(2)ICl and Cl(2) (-)) not observed ...

Neutron reflectometry was used to determine the distribution of salt ions and water in thin poly(acrylic acid) and poly(allylamine hydrochloride) polyelectrolyte multilayers assembled with and without salt. Increasing salt concentration reverses the exclusion of water from the substrate region, eventually leading to an asymmetric segregation of water near the substrate at high salt concentratio...

The importance of dietary salt may explain why bees are often observed collecting brackish water, a habit that may expose them to harmful xenobiotics. However, the individual salt preferences of water-collecting bees were not known. We measured the proboscis extension reflex (PER) response of Apis mellifera water foragers to 0-10% w/w solutions of Na, Mg and K, ions that provide essential nutri...
