Pompano farming at Vethalai using low-cost cages: Technology demonstration initiative by Mandapam RC
No full textAn artisanal type of cage was fabricated at Mandapam Regional
Centre with 6×6 m outer and 5×5 m inner square frame,
which is made of 50mm GI pipe for farming demonstrations involving
local fishermen at Vethalai village, Ramnad District, Tamil Nadu.The ongoing pompano farming
demonstration in an artisanal type of sea cages is a way forward for
the spread of mariculture in India.

Artisanal innovation in cage farming of pompano at Vethalai, Ramanathapuram
No full textOn 25th July 2012, pompano from an artisanal cage was
harvested. The total harvest was 92 kg, the length and weight
ranges observed were 16 to 32 cm and 62 to 433 grams.The harvest was handed over to the farmer Shri.Nagadoss
by Dr. G. Gopakumar, Scientist-in-Charge. The farm gate price
for the harvested pompano was `120/kg- and it was sold by
the merchant in the retail market at `180/kg-.

GaAs/AlGaAs heterostructure based micro-hall sensors and response to A.C. excitation
No full textHall sensors are fabricated from GaAs/AlGaAs based heterostructures. The sensors are characterized for sensitivity using A.C and D.C. excitation techniques w.r.to a known magnetic field in the range of 0-100Oe. Sensitivities of the order of 1000V/AT are obtained with a low variation of 0.15% in the temperature range of 30°C-100°C. A.C excitation (30Hz to 1 kHz) for the sensor current and phase-sensitive detection of the Hall Voltage are used to eliminate thermo-emfs and its drift with a consequent improvement in data acquisition rates of >50% over that of D.C excitation. This improves scan rates in applications such as magnetic flux leakage (MFL) measurements. The sensitivity is independent of the frequency of excitation as expected; however, the zero-field Hall voltage 'offset' value is found to have small frequency dependence.</p
Correction: One-step coelectrodeposition-assisted layer-by-layer assembly of gold nanoparticles and reduced graphene oxide and its self-healing three-dimensional nanohybrid for an ultrasensitive DNA sensor
No full textCorrection for ‘One-step coelectrodeposition-assisted layer-by-layer assembly of gold nanoparticles and reduced graphene oxide and its self-healing three-dimensional nanohybrid for an ultrasensitive DNA sensor’ by Jayakumar Kumarasamy, et al., Nanoscale, 2018, DOI: 10.1039/c7nr06952a. The names of two of the co-authors are given incorrectly in the published article. “Jayakumar Kumarasamy� should instead be listed as “Kumarasamy Jayakumar�, and “Dharuman Venkatraman� should instead be listed as “Venkataraman Dharuman� as shown in the corrected author list above.
