Intercropping is one of the important components of habitat management based on the principle of reducing insect pests by increasing the diversity of an ecosystem. A field experiment was conducted to find the influence of different intercropping systems in relation to pests and natural enemy incidence. Mean insect numbers, percent damage and natural enemy… (More)
We show that the technique of Frequency Resolved Admittance Spectroscopy (FRAS) allows the identification of deep traps with reduced measurement effort compared to Deep Level Transient Spectroscopy (DLTS). This is shown by the analysis of radiation defects introduced in n-type 4H-SiC 1700V Schottky diodes.
Spatial variability and site specific fertility management of six soil parameters viz. soil pH, soil organic carbon, available nitrogen, available phosphorus, available potassium and available sulphur were undertaken using both classical statistics and geostatistical analysis for the intensively cultivated research farm of Indian Agricultural Research… (More)
Electronic circuit simulation programs like SPICE have built-in models for semiconductor devices like MOSFET and BJT. However, they do not provide models for electrochemical sensors like ISFETs (Ion-Sensitive Field-Effect Transistors). This paper presents a behavioral macromodel for ISFET-based pH-sensors implemented using PSPICE™. The macromodel is then… (More)
An electric distribution system plays an important role in achieving satisfactory power supply. The quality of power is measured by voltage stability and profile of voltage. But because of losses in distribution system, its voltage profile affects. Basically, the losses could be defined as the difference between the metered units energy input into the… (More)
As shale gas resources have emerged as a viable energy source, their characterization has gained significance. The organic content in these shales which are measured by their TOC ratings, influence the compressional and shear velocities as well as the density and anisotropy in these formations. Consequently, it should be possible to detect changes in TOC… (More)
With the emergence of the shale gas resources as an important energy source, the characterization of mudrocks has gained significance. To be a good resource, mudrocks need to contain sufficient organic content and respond effectively to hydraulic fracturing. Variations in total organic carbon, as well as brit-tleness which is a function of mineralogy,… (More)
