the impact of morphological awareness on the vocabulary development of the iranian efl students

this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...

The Photosynthetic Apparatus of Rhodospirillum Molischianum

By varying the light intensity and temperature during growth it is possible to obtain cultures of Rhodospirillum molischianum in which the specific bacteriochlorophyll contents differ by as much as fivefold. We used such cultures to compare the changes in the electron microscopic appearance of the cells with the changes in the amount and bacteriochlorophyll content of chromatophore material iso...

The photosynthetic apparatus of Rhodobacter sphaeroides.

Functional and ultrastructural studies have indicated that the components of the photosynthetic apparatus of Rhodobacter sphaeroides are highly organized. This organization favors rapid electron transfer that is unimpeded by reactant diffusion. The light-harvesting complexes only partially surround the photochemical reaction center, which ensures an efficient shuttling of quinones between the p...
