BFV Quantization of Relativistic Spinning Particles with a Single Bosonic Constraint

Using the BFV approach we quantize a pseudoclassical model of the spin one half relativistic particle that contains a single bosonic constraint, contrary to the usual locally supersymmetric models that display first and second class constraints.Comment: 5 p., Latex, IF-UFRJ-94-1

An operator approach to BRST invariant transition amplitudes

The transition amplitudes for the free spinless and spinning relativistic particles are obtained by applying an operator method developed long ago by Dirac and Schwinger to the BFV form of the BRST theory for constrained systems.Comment: 10 pages, Latex, IF-UFRJ-9

Longbeak common dolphin Delphinus capensis (Gray, 1828) stranded at Karwar, Karnataka

A dead specimen of longbeak common dolpin Delphinus capensis (Gray, 1828), locally called ‘handi meenu’ which was floating approximately 500 m away from sea shore of Aligadda village, Karwar was brought ashore by fishermen and instructors of Karavali sports club in the morning hours of 08.01.2011

Three baleen whales washed ashore along Uttara Kannada coast of Karnataka

Three instances of stranding baleen whales were observed along the coast of Uttara Kannada district of Karnataka during July and August 2016. All strandings were recorded from the southern part of the district.The first whale was washed ashore on 20th July 2016 at Ramangindi, Dhareshwar, 12 km south of Kumta (140 21’ 710"N and 740 24’ 360E). The whale was in a decomposed condition when washed ashore. The post mortem was carried out by a veterinary doctor. It was identified as Bryde’s whale Balaenoptera edeni. The total length of the male whale was 44 feet weighing approximately 10 tonnes (Fig. 1). The second whale washed ashore on 27.7.2016 at Hollangadde 7 km from Kumta (140 27’ 432" N and 740 22’ 615" E was also in decayed condition. It was identified as baleen whale and measured 46 fee
