Numerous technologies have been investigated for mitigating air pollutant emissions from swine barns. Among them, algal photobioreactors (PBRs) can remove and utilize pollutants such as CO2 NH3 barn exhaust. However, a challenge to PBR operation is that it involves multiple system input parameters output goals. A key question then how determine the appropriate concentrations in this case. Conve...

BACKGROUND Encyrtid secondary parasitoids of Delphacidae have not been recorded in Japan. However, they may play an important role in the rice ecosystem because they can reduce the number of Dryinidae, the natural enemies of rice planthoppers. NEW INFORMATION We found two encyrtid species, Cheiloneurus exitiosus (Perkins, 1906) and Helegonatopus dimorphus (Hoffer, 1954), from rice paddies and...
