3A1 Electrical conductivity (EC) of 1:5 soil/water extract This test on milled air-dry sample at a soil/water ratio of 1:5 for 1 h is suitable for use on all soils, irrespective of whether acidic or alkaline. It usually underestimates the soluble salt status of soils containing natural or added gypsum, particularly if ≥ 1% of gypsum is present. Such soils would have an EC of about 2 dS/m. Soil ...

Electrokinetic flows with heterogeneous conductivity configuration occur widely in microfluidic applications such as sample stacking and multidimensional assays. Electromechanical coupling in these flows may lead to complex flow phenomena, such as sample dispersion due to electro-osmotic velocity mismatch, and electrokinetic instability (EKI). In this work we develop a generalized electrokineti...

this study was conducted to evaluate the responses of two greenhouse tomato cultivars to nutrient solutions' electrical conductivity (ec). two cluster type greenhouse tomato cultivars (razan and ergon) were grown in perlite in a glasshouse hydroponic system. the grown plants were daily fed with either constant ec nutrient solutions (ecs 2, 3 ds m-1) or nutrient solutions of alternatively c...

Early detection of Breast Cancer is currently emerging as a big clinical entity requiring a non invasive, radiation less, harmless, cost effective diagnostic technique. Survival is improved if detected early. Breast Cancer is the second most common cancer in India. Health corporate system of India is urgently requiring a cost effective, noninvasive novel technique like “Electrical Impedance Tom...

The use of brackish groundwater (BGW) to supplement irrigation shortfalls has increased because decreasing surface water availability in the arid areas southern United States. Reuse reverse osmosis (RO) concentrate, a by-product resulting from desalination BGW, can increase portfolio. This 2-yr greenhouse study aimed quantify changes physical and thermal soil properties, evapotranspiration (ET)...

A geostatistical analysis of soil salinity in an agricultural area in the San Joaquin Valley included measurements of electrical conductivity of soil paste extract (EC3 and water content of soil samples supplemented by surface measurements of apparent electrical conductivity (EM”). Prediction of soil salinity at unsampled points by cokriging log@C3 and EMa is worthwhile because EM” measurements...

The use microalgae biomass for the production of biofuels has received great attention in the last decades. Microalgae biofuels could be important alternative to conventional biofuels since microalgae could be produced at high rates without the need of neither arable land, potable water or competition with food. However, the high energy intensive harvesting processes are limiting the commercial...

Electrolytes play an integral role in the successful operation of any battery chemistry. The reemergence sodium-ion (SIB) chemistry has therefore rejuvenated search for optimized SIB salts and solvents. Recent experiments have found that 1 M NaPF 6 ethylene carbonate (EC) propylene (PC), EC 0.5 : PC (w/w) is best binary electrolyte SIBs. However, mathematical models, to elucidate these experime...
