Analysis of Aggregate Structure in Food Protein Gels with the Concept of Fractal.

Effect of pH on Structural Properties of Heat-Induced Whey Protein Gels

Formation and structure of whey protein heat-induced gels (100 mg mL-1) through heat treatment at 80 °C and pH modifications at three pH values of acidic (2), isoelectric (5.6) and neutral (7) were studied. The obtained results indicated that the nature of the primary gel networks was different at each pH value. The heat-induced gels produced at pH of 2 and 7, had acceptab...

Determination of Agricultural Sulfur Effects on the Soil Structure Using Fractal Geometery and Aggregate Stability Indices

Due to unsuitable soil physical conditions, calcareous soils, and the existence of a huge amount of sulfur in the country, the study of sulfur effects on the soil structure and other soil properties is necessary. Therefore, the effects of different rates of sulfur including: 0, 750, 1500 and 3000 kg/ha, when accompanied by Halothiobacillus neapolitanus bacteria, on the soil properties in the co...

Evaluation of fractal dimensions for analysis of aggregate stability

برآورد پارامترهای نفوذ آب به خاک با استفاده از مدل فرکتالی ریو و اسپوزیتو

Quantitative description of the spatial variability of soil hydraulic characteristics is crucial for planning, management and the optimum application. Field measurement of infiltration is very expensive, time-consuming and laborious. Soil structure also important effects on water infiltration in the soil. The objectives of this study were to determine the spatial variability of water infiltrati...

Pore surface fractal dimension of sol-gel derived nanoporous SiO2-ZrO2 membrane

In this work, SiO2 –ZrO2 mixed oxides was prepared by the polymeric sol–gel route. The characterization of pore structure, which determines the permeation process of membrane, is of great importance. So far, most investigations have focused on such pore structure as specific surface area and pore size distribution, but the surface fractal, the important parameter reflecting the roughness of por...
