this study was conducted to investigate some moisture-dependent engineering properties of russian olive fruit including fruit dimensions, one thousand seed mass, surface area, sphericity, bulk and true density, angle of sliding and static friction coefficient against different surfaces. the physical properties of russian olive fruit were evaluated as a function of moisture content in the range ...

Changes in the physical properties (size, particle density, bulk density, shrinkage and porosity) and fluidization behaviour of cut green beans with change in moisture content during drying were investigated using a heat pump and fluidized bed dryers. Three length:diameter ratios 1:1, 2:1, 3:1 of cut green beans were considered. All drying experiments were conducted at 50 + 2 0 C and 13 + 2 % R...

soil physical properties have an important role on vegetation growththrough affecting the development of root system. the aim of this study was toinvestigate the trampling effect of livestock grazing on soil physical properties andvegetation cover changes. the experiment was conducted on three range conditionsites (reference, key and critical area) with ten frequencies in hosseinabadekudistan i...

Increasing demands for cement, iron and steel industries for refractories with suitable workability in severe conditions (without any environmental risks), make the refractories’ researches to be an active area. Refractories containing Spinel has been developed with addition of chromia as a substitute in refractories using Magnesite - chromite. In this research, different amounts of Cr2O3 were ...

It has been observed that anisotropic nature of rocks is assumed to be caused by disparity in their petrography (mineralogy, texture and micro-structures) including physical properties. These variations have been revealed to occur even in locations where there are only a few centimetres apart on most outcrops. Furthermore, comparable rock types in most localities may not yield the same engineer...

As far as Iran is concerned in arid and semi-arid region and amount of water is limited, improvement of water consuming is very important. One of the ways for storing water is to use superabsorbent polymer. So, this research compared normal and deficit irrigation methods by considering the effects of stockosorb (0.1% and 0.3% by volume) and zeolite (10 weight% and 15 weight%) in two sandy soils...

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...
