Damare, V.S.
The marine nitrogen cycle is important ecologically as nitrogen is a nutrient required by phytoplankton, which as primary producers, form the basis of the marine food chain. Nitrate and nitrite ions are utilised as terminal electron acceptors for respiration by microorganisms during the unavailability of oxygen. The anaerobic processes of nitrogen transformation, such as denitrification and anammox are prolific in the oxygen minimum zones of the marine environment. Eukaryotic microorganisms or protists form a major part of picoplankton and nanoplankton in the pelagic water column of the oceans and seas. These also thrive and flourish in the marine sediments and are involved in various biogeochemical activities along with bacteria. These are known to be involved in the nitrogen cycle by various enzymes involved in denitrification, nitrification, and ammonification. The fungi, diatoms, dinoflagellates, and foraminifera are the most widely known eukaryotes to be involved in nitrogen cycling. These eukaryotic microorganisms belong to various supergroups in the tree of life and contribute to the marine nitrogen cycle in some way or the other. This chapter summarises the various eukaryotic microorganisms involved in the different processes of the nitrogen cycle, as well as those whose involvement is still ambiguous.

Lobo, J.Z.; Valaulikar, Y.S.
In this paper we obtain the Lie invariance condition for second order partial differential equations. This condition is used to obtain the determining equations of the 1-dimensional wave equation with constant speed. The determining equations are split to obtain an overdetermined system of partial differential equations which are solved to obtain the symmetries of the wave equation. By making an appropriate transformation between the dependent and independent variable, the wave equation is reduced to an easily solvable ordinary differential equation. We solve this resulting differential equation to obtain the solutions of the wave equation. In particular, the one dimensional wave equation with unit speed has been solved.
