Dispersive liquid-liquid microextraction (DLLME) followed by gas chromatography-massspectroscopy (GC-MS) was used to analyses of components of floral-water of Rosmarinusofficinalis . Some effective parameters such as volume of extraction, disperser solvents andsalt effect were studied by a full factorial design for obtain the optimum condition. The maincompounds of the floral-water of Rosmarinu...

recent droughts and indiscriminate use of ground water for agriculture, is the main problems of the especially desert country.water crisis has gripped all of country plains, and due tothe reduction of surface water resources and successive droughts, illegal exploitation of ground water resources is increasing.the knowledge of the water balance plains can be helped in the water resources managem...

physical properties of agricultural products such as volume are the most important parameters influencing grading and packaging systems. they should be measured accurately as they are considered for any good system design. image processing and neural network techniques are both non-destructive and useful methods which are recently used for such purpose. in this study, the images of apples were ...

Several evidences have indicated that many nuclei in the brain have critical role in water intake. Angiotensin II is one of the most important neurotransmitters involved in regulation of fluid homeostasis. In this study, the interaction of i.c.v. injection of captopril and histamine on water intake in adult male water-deprived rats was investigated. Rats were implanted with guide cannula aimed ...

the dispersive liquid–liquid microextraction (dllme) method for determination of pb +2 and cd +2 ions in the environmental water samples was combined with inductively coupled plasma-atomic emission spectrometry (icp-aes). ammonium pyrrolidine dithiocarbamate (apdc), chloroform and ethanol were used as chelating agent, extraction solvent and disperser solvent, respectively. some effective parame...

OBJECTIVES To evaluate the cerebellar structure in sodium benzoate (NaB) or ascorbic acid (AA) treated rats. METHODS This experimental study was conducted between May and September 2013 in the Laboratory Animal Center of Shiraz University of Medical Sciences, Shiraz, Iran. The rats received distilled either water, NaB (200mg/kg/day), AA (100mg/kg/day), or NaB+AA. The hemispheres were removed ...

the use of temporary runoff and underground dried-up water courses has been implemented by managers in recentyears to compensate for water shortages in arid and semi-arid regions. one way to use this water is to set up anunderground sandy dam in front of such water courses; selecting a suitable water course is the most important issue ofsuch a purpose. in the present research, this matter was i...

water quality is a most important factor in areas facing water crisis the survival of which is based upon it. in a determination of water value the factors that should be attended to are: the given volume, specified quality(preservation value), as well as the specific time and place.valuation of water in iran is dependent on types of exploited water resources which include: human consumption(qu...

The microphase separation of hydrated perfluorinated sulfonic acid membrane Nafion was investigated using Dissipative Particle Dynamics (DPD). The nafion as a polymer was modelled by connecting coarse grained beads which corresponds to the hydrophobic backbone of polytetrafluoroethylene and perfluorinated side chains terminated by hydrophilic end particles of sulfonic acid groups [1, 2]. Each f...
