Capacitance sensors such as Decagon 10HS and 5TE are increasingly used for soil water content (θ) estimation. However, their reliability and limitations in clayey soils irrigated with saline waters have not been completely characterized under field conditions. Four levels of soil water content...

Graphite nanoplatelets (GnPs), obtained by sonicating the expanded graphite, were employed to simultaneously enhance the thermal (k) and electrical (σ) conductivity of organic form-stable phase change materials (FSPCMs). Using the method of in situ polymerization upon ultrasonic irradiation,...

To achieve satisfactory results with vermiculture, it is important to know how many times to rinse cattle manure to eliminate salts. Treatments under evaluation were 0, 1, 2, 3, 4, 5, 6 or 7 rinses in a tap water: manure ratio of 1 : 1 (v/v). Electrical Conductivity (EC), Biomass of Worms (BW)...

A study was carried out under greenhouse conditions to establish the role of substrate physical and chemical properties. Pine bark and coal rubble were mixed at 100, 75, 50, 25, and 0% by volume. A farmers’ standard practice (50% pine bark + 50% sand) was included as a control. The experiment...

This paper deals with the derivation of a formula developed empirically in a previous article. The equation allows the calculation of the average electrical conductivity of two-component random media over the whole range of fraction and a wide range of resistivity ratio of the components....

New and literature measurements are compared for the electrical transport properties of densely packed spherical particles. Measurements of electrical conductivity in cubic lattices are presented and were found to agree closely with numerical solutions for the conductivity presented in the...

Electrical current density of charged particles across a rarefied gas of neutral particles under shear flow is analyzed in the limit of small electric fields. The concentration of the charged species is assumed to be much smaller than that of the neutral species so that the interactions of...

This work presents the results of numerical simulations concerning the electrical conductivity of two-component random resistor networks in d=3 as a model of composite media. Finite difference calculations have been carried out for several system sizes, conductance ratios and occupation numbers....

Saffron (Crocus sativus L.) is the most strategic and expensive crop in the Islamic Republic of Iran. Shortage and salinity of irrigation water are two major constraints that influence saffron production in arid and semi-arid regions. The objective of the present study is to investigate the...
