We introduce Emerson, a scripting language for virtual worlds that are seamless, scalable, and federated. These worlds present a number of unique challenges. Most importantly, scripts that specify the behavior of the world are distributed across many hosts and users may generate and host scripts. These constraints imply features not common in other systems, such as frequent use of asynchronous ...

The discovery of the Emerson enhancement effect in photosynthesis (3-6, 8) led to the suggestion that there are 2 photochemical reactions necessary for complete photosynthesis. A likely hypothesis is that the 2 reactions are carried on by different forms of chlorophyll a (10, 11). The enhancement effect in photosynthesis has been studied extensively in several laboratories (19) and it has been ...

Twelve new localities are reported for the following four Embiratermes species: E. ignotus Constantino, 1991; latidens (Emerson & Banks, 1957); silverstrii (Emerson, 1949); and spissus 1957). The extend distribution span from 940 km up to 1,800 km. is recorded beyond Amazonia first time. enteric valve armature workers of these species provided.
