The use of exclosure for ecological restoration has become an increasingly vital approach to reversing degraded lands. Its effectiveness in restoring lands could be varied with differences climate, vegetation type and soil properties. Thus, the objective this study was determine effect on selected physical chemical properties soil. A six-year-old adjacent open land same history land-use types w...
Electrical Impedance Tomography uses surface electrical measurements to image changes in the conductivity distribution within a medium. This technique was applied to the measurement of gastric motility by imaging conductivity changes in the abdomen after ingestion of liquid. Preliminary results show good correlation with typical clinical measurements. composition, and caloric content have a lar...
Lanthanum strontium cobalt oxide (LSCO) has been employed as cathode and intercollector materials for solid oxide fuel cells (SOFCs). In the present study, the La0:5Sr0:5CoO3 layer was deposited by atmospheric plasma spray (APS). The effect of heat treatment on microstructure and electrical conductivity of the LSCO deposits was examined. The electrical conductivity of the deposits along the lam...
The general characteristics of salt-affected soils and soil structure degradation process are partially known, but the effects of saline and sodic conditions on mechanical properties of soils are not well recognized. In this study, the effects of electrical conductivity (EC) and sodium adsorption ratio (SAR) on tensile strength of soils with different organic carbon contents were assessed under...

Consecutive tomato monoculture cropping (CTM) obstacles severely restrict the development of facility industry in China. However, effect CTM on soil fungal community greenhouses is still unclear. Here, we aim to identify variation chemical properties and associated with for 1, 3, 5, 9 13 cycles. The results indicated that led a significant increase total phosphorus (TP) electrical conductivity ...
Fluoride contamination has now become an emerging concern in agroecosystems. A diagnostic survey was conducted across the fluoride (F-) contaminated wetlands of Kuttanad, India with aim to examine influence edaphic factors on F- concentration soils. The soils (Inceptisols) predominantly sandy had a substantial percentage clay and soil characteristics such as bulk density (BD), moisture, tempera...
The treatment of the yeast industry wastewater was investigated by nanofiltration (NF) membrane process on a pilot scale. Two wastewaters were used as feed: (i) dilute wastewater with COD 2000 mg/L and (ii) concentrate wastewater with COD 8000 mg/L. The permeate flux, COD retention, color and electrical conductivity (EC) removal were evaluated in relation to trans-membrane pressure and long-ter...
Meltwater discharge and electrical conductivity were measured in eight 1 3 1 m lysimeters, and snow accumulation and electrical conductivity of melted samples were measured in snow pits during four snowmelt seasons at Mammoth Mountain, California. The peak snow-water equivalent ranged from 0.57 to 2.92 m over the four melt seasons. Lysimeter discharges ranged from 20% to 205% of the mean flow; ...
Formamidinium lead iodide (FAPbI3) perovskite as a superior solar cell material was investigated in two polymorphs at high pressures using in situ synchrotron X-ray diffraction, FTIR spectroscopy, photoluminescence (PL) spectroscopy, electrical conductivity (EC) measurements, and ab initio calculations. We identified two new structures (i.e., Imm2 and Immm) for α-FAPbI3 but only a structural di...
