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 en...

It has long been viewed that the maintenance of osmotic balance in response to high salt intake is a passive process that is mediated largely by increased water consumption to balance the salt load. Two studies in this issue of the JCI challenge this notion and demonstrate that osmotic balance in response to high salt intake involves a complex regulatory process that is influenced by hormone fl...

The title salt, C(14)H(16)N(4) (2+)·2C(14)H(9)O(4)S(2) (-)·2H(2)O, was obtained by the co-crystalization of 2,2'-dithio-dibenzoic acid with 1,4-bis-(imidazol-1-ylmeth-yl)benzene. It consists of 2-[(2-carb-oxy-phen-yl)disulfan-yl]benzoate anions, centrosymmetric 1,1'-(p-phenyl-enedimethyl-idene)diimidazol-3-ium cations and water mol-ecules. O-H⋯O, O-H⋯S and N-H⋯O hydrogen-bonding inter-actions a...

In the title salt, (C(5)H(14)N(2))[FeCl(4)(H(2)O)(2)], the Fe(II) cation is coordinated by four Cl(-) anions and two water mol-ecules in a distorted octa-hedral geometry. The piperazine ring adopts a normal chair conformation. Inter-molecular N-H⋯Cl, N-H⋯(Cl,Cl) and O-H⋯Cl hydrogen bonding is present in the crystal structure.

The cell surface hydrophobicity of 14 encapsulated and 21 non-encapsulated coagulasenegative staphylococci (CN staph) as determined with the salt aggregation test (SAT) as well as with the xylene-water method ranged widely. Non-encapsulated strains adhered well onto fluorinated poly(ethylene-propylene) (FEP), irrespective of the hydrophobicity of the cell surface. The ability of the encapsulate...

kochia scoparia is a salt resistant plant that can be used in producing forage in the areas with salt water and soil resources. one of the problems which produce the forage plants in these areas decreases the function and quality of the forage in irrigation condition with salt water. therefore, using the chemical fertilizers can be considered as a useful solution. this study was conducted to ev...

Objectives. Extra radicular diffusion of hydrogen peroxide associated with intracoronal teeth bleaching was evaluated. Methods. 108 intact single rooted extracted mandibular first premolars teeth were selected. The teeth were instrumented with WaveOne system and obturated with gutta percha and divided into four groups (n = 27) according to the bleaching materials used. Each main group was divid...

this study is an attempt to develop an integrated methodology to predict the impact of the caspian sea on flooding using geographic information systems (gis) and hydrodynamic modeling. a rise in the sea level might lead to major flooding events, and have a severe impact on the spatial development of cities and regions. the feasibility of simulating a flood event along a drain channel is evaluat...
