چکیده

Article Info Twenty one days pre-decomposed substrates, teak leaf litter (TLL), paper mill sludge (PMS) and pressmud (PM) in combination with cowdung was subjected to vermicomposting using the epigeic earthworm, Perionyx ceylanensis for 60 days. The phosphatase enzymes—acid phosphase and alkaline phosphase were analysed in vermibed substrates of TLL, PMS and PM on 0, 15, 30, 45 and on 60 th day of vermicomposting. The activity of the acid and alkaline phosphatase enzymes were found to be increased in all the vermibed substrates towards the end of vermicomposting. The results also showed significant variation (p=0.05) in phosphatase enzyme activities with respect to different vermibed substrates. Accepted: 28 March 2017 Available Online: 20 May 2017

Evidence of the Potential Shift Mechanism in Crevice Corrosion (RESEARCH NOTES)

Previous research has indicated a qualitative resemblance between the current distribution along actively corroding crevice walls and currents measured in corresponding anodic polarization plots. Using detailed measurements of the potential gradient along the crevice, a semi-quantitative current distribution was calculated for the crevice wall using a double numerical differentiation method. Th...

Analytical quantum current modeling in GNSFET

Carbon nanoscrolls (CNSs) belong to the same class of carbon-based nanomaterialsas carbon nanotubes. As a new category of quasi one dimensional material Graphene Nanoscroll (GNS) has captivated the researchers recently because of its exceptional electronic properties like having large carrier mobility. GNS shape has open edges and no caps unlike Single Wall Nanotubes (SWNTs) which are wou...

A New Strategy for Simultaneous Compensation of Instantaneous Reactive Power and Harmonics of Non-Linear Loads (RESEARCH NOTE)

This paper presents a new control method for simultaneous compensation of instantaneous reactive power and current harmonics by parallel active filters (PAFs). Reference compensating currents of PAF are calculated using the subtraction of instantaneous power from its average value. In this way, it is possible omitting high/low pass filter(s) from the control circuit of PAF, which usually result...
