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

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

Unusual landings of large sized Yellowfin tuna by purse seiners at Karwar, Karnataka

Unusual landings of large sized Yellowfin tuna Thunnus albacares (Bonnaterre, 1788) was observed at Baithkol Fisheries Harbour, Karwar during the period 16th to 22nd February 2020. Six tunas were landed by two purse-seiners with individual weights ranging from 68 kg to 103 kg. One purse-seine unit landed with only one yellowfin tuna weighing 68 kg in the early morning hours of 16.2.2020. The other multiday purse-seine unit of OAL 19.8 meter overall length (OAL) fitted with a 350 hp Sonatrac engine was operated at a depth of 54 meter off Belekeri (N 140 38’ 100” E 0730 52’ 500”) during night hours on 18.2.2020 and four yellowfin tuna weighing 103, 97, 82 and 78 kg each were hauled in and sent immediately by a carrier boat to landing centr
