Transfection describes the introduction of foreign material into eukaryotic cells using a virus vector or other means of transfer. The term transfection for non-viral methods is most often used in reference to mammalian cells, while the term transformation is preferred to describe non-viral DNA transfer in bacteria and non-an

We see only the effect, not the source, as a large diffuse light passes
rapidly under the subs hull. Moments later a shockwave, like an underwater
sonic boom, impacts the sub, slamming it sideways.

Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma

and riffle are constructed considering the original slope and flow. Riffle was made of gravels, therefore not settled successfully. Stepping stones installed in several place also function like riffle.
Lastly, a riverside wetland was constructed in the stream. It was supposed to be a site for removing pollutants and controlling water flow like other wetlands but destructed after some flood.
The sulphated polysaccharides extracteds from marin brown algae, represent a source of marine compounds with potential applications in medicine and main compounds of fucoidan are L-fucose and sulphate ester groups.
It has been reported that fucoidan inhibited cancer(Aisa et al. 2005; Liu et al. 2005).
Enhanced the immune functions in cell studies(Blondin et al. 1996;Hsu et al. 2001).
