Bioluminescence is a phenomena in an organism which produces luminescence on quorum sensing and this phenomenon has been explored in many fields like invivo diagnostics, marker technology, protein engineering etc. and has immense potential as future torchlight too with the aid of technologies. Present study aims at the screening and identification of bioluminescent bacteria from different marin...

With a coastline of 3,260 km, a coastal area with more than 4,000 islands, and many lagoons giving protection against the waves and wind, Vietnam has great potential for seacage aquaculture. In Vietnam, seacage culture of lobsters started in the province of Khanh Hoa in 1992 and has expanded significantly around south-central Vietnam since 2000. Panulirus ornatus (ornate spiny lobster) is the m...

Intracellular recordings at the neuromuscular junction of the dactyl opener muscle and the abdominal phasic flexor muscle of intermolt lobsters were made in the presence and absence of the steroid hormone, 20-hydroxyecdysone (20-HE). Evoked excitatory junctional potentials (EJPs) were recorded from both muscles; spontaneous miniature excitatory junctional potentials (MEJPs) were recorded from t...

Depredation of southern rock lobster (Jasus edwardsii) within fishing gear by the Maori octopus (Pinnoctopus cordiformis) has economic and ecological impacts on valuable fisheries in South Australia. In addition, depredation rates can be highly variable resulting in uncertainties for the fishery. We examined how in-pot lobster predation was influenced by factors such as lobster size and sex, se...

A (simple undirected) graph G = (V,E) with m edges is graceful if it has a distinct vertex labeling f : V −→ {0, 1, 2, 3, . . . ,m} which induces a set of distinct edge labels {|f(u)− f(v)| | uv ∈ E, u, v ∈ V }. The famous Ringel-Kotzig conjecture [9, 15] is that all trees are graceful. The base of a tree T is obtained from T by deleting its one-degree vertices. A caterpillar is a tree whose ba...
