Absorption Efficiencies and Biochemical Fractionation of Assimilated Compounds in the Cold Water Appendicularian Oikopleura Vanhoeffeni
Using 68Ge : 14C dual-labeling, we investigated the absorption efficiency of diatom carbon for the cold water appendicularian Oikopleura vanhoeffeni. The absorption efficiency of bulk carbon (mean 5 67%) was not influenced by body size or ingestion rate. For the first time for a pelagic tunicate, food and feces were fractionated into their major biochemical constituents (i.e., low-molecular-wei...

متن کاملDNA interference: DNA-induced gene silencing in the appendicularian Oikopleura dioica.
RNA interference is widely employed as a gene-silencing system in eukaryotes for host defence against invading nucleic acids. In response to invading double-stranded RNA (dsRNA), mRNA is degraded in sequence-specific manner. So far, however, DNA interference (DNAi) has been reported only in plants, ciliates and archaea, and has not been explored in Metazoa. Here, we demonstrate that linear doub...

15 صفحه اولthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
