Reduction of NaCl content in restructured dry-cured hams: post-resting temperature and drying level effects on physicochemical and sensory parameters. The effects of post-resting temperature (5 oC, 15 oC and 25 oC) and drying level (low and high, corresponding to final water contents (w/w) of 57% and 50%, respectively) were evaluated in restructured dry-cured hams. The reduction of NaCl content...

In the present study, effects of NaCl concentrations (0, 20, 40 and 80 mM) were investigated on Ceratophyllum demersum. Macronutrients N, P and K and micronutrients Zn and Cu were significantly decreased by NaCl salinity. In general, however, Fe and Mn contents of macrophyte tissues increased. As a result, NaCl toxicity disturbed the uptake and translocation of macro and micronutrients in the m...

The conductivity of a poly(3,4-ethylene dioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) film is enhanced by more than 100-folds on adding some organic compounds into PEDOT:PSS aqueous solutions or by treating the PEDOT:PSS film with organic solvents, such as ethylene glycol (EG), 2-nitroethanol, methyl sulfoxide or 1-methyl-2-pyrrolidinone. The mechanism for this conductivity enhancement wa...

In the present study, effects of NaCl concentrations (0, 20, 40 and 80 mM) were investigated in Ceratophyllum demersum. Macronutrients N, P and K and micronutrients Zn and Cu were significantly decreased by NaCl salinity. In general, however, Fe and Mn accumulation showed to increase. As a results, NaCl toxicity disturbed the uptake and translocation of macro and micronutrients in the macrophyt...

Nine time-domain reflectometry (TDR) probes, 2 to 10 cm long, were evaluated by comparing their measurement accuracy of TDR-pulse travel time in a sand and sandy loam soil, and electrical conductivity in NaCl solutions. TDR probes <2.5 cm in length generated troughhaped TDR waveforms with rounded corners at the points of the pulse reflection from the probe ends. The sharpness of the pulse refle...

Using freshly precipitated manganese-diethyldithiocarbamate (Mn(DDTC)(2)) as a new reagent, a solid phase extraction method (SPE) has been developed for the extraction of Cd(II) and Zn(II) in aqueous fertilizer samples. A sample solution of 300 mL was taken and 0.10 g of freshly precipitated Mn(DDTC)(2) was added. After adding a phosphate buffer solution, the mixture was stirred at 10 min, filt...

soil hydraulic properties such as saturated and unsaturated hydraulic conductivity play an important role in environmental research. since direct measurement of these soil hydraulic properties is time-consuming and costly, indirect methods such as pedotransfer functions and artificial neural networks (ann) were developed based on readily available parameters. in this study, the use of ann to pr...

GRB-PAP1 is a continuous line of epithelial cells derived from a rabbit renal inner medulla. Elevation of the NaCl concentration in the medium bathing these cells strongly induced the expression of a soluble protein with an apparent molecular mass of 39 kDa. The protein, purified by affinity chromatography with Amicon Matrex Gel Orange A, had enzyme activity characteristic of aldose reductase (...

Twenty-two surface soil samples (0-20 cm) from Fars province were extracted by five extractants (i.e., DTPA, 1.5 M NH4H2PO4, 0.1 NH3PO4, 0.05 MNa2EDTA, and 1% Na2EDTA) and used in a 7-week greenhouse experiment which was a 22 × 3 factorial with 22 soils (clay 16-63% pH 7.8-8.2 electrical conductivity 0.32-1.78 dS m-1 calcium carbonate equivalent 28-63% organic matter 1.1-4.9% cation exchange ca...
