    The epoxidation of ethylene involves its reaction of oxygen according to the following stoichiometry: 7 H 2 C=CH 2 + 6 O 2 → 6 C 2 H 4 O + 2 CO 2 + 2 H 2 O. The direct reaction of oxygen with alkenes is useful only for this epoxide. Modified heterogeneous silver catalysts are typically employed.

    Rice-cum-fish culture is the use of land for the culture of both rice and aquatic organisms. One form of rice-cum-fish culture is the introduction of brood-stock or seed into flooded paddy fields, often modified for aquacultural purposes. Another form of rice-cum-fish culture is where rice and fish are raised on the same land in different seasons.
