A procedure permitting the isolation of large amounts of cytochrome b-559 from chloroplasts of barley is described. The isolated cytochrome b-559 has an apparent molecular weight of 120,000. The protein equivalent weight per mole of heme is 30,000. Depending on the electrophoretic conditions used, this molecule can be dissociated into components with apparent molecular weights of 31,000, 30,000...

Toxic Cu (II) effect on cytochrome b(559) under aerobic photoinhibitory conditions was examined in two different photosystem II (PSII) membrane preparations active in oxygen evolution. The preparations differ in the content of cytochrome b(559) redox potential forms. Difference absorption spectra showed that the presence of Cu (II) induced the oxidation of the high-potential form of cytochrome ...

A new peer-reviewed study in England shows that children have an increased danger of getting cancer if they live within three to five kilometers (2 to 3 miles) of certain kinds of industrial facilities.[1] The study, by E.G. Knox and E.A. Gilman, finds that the danger is greatest within a few hundred yards of pollution sources and tapers off with distance. The incidence of childhood cancers per...

Cytochrome b 559 (Cyt b 559) is one of the essential components of the Photosystem II reaction center (PSII). Despite recent accomplishments in understanding the structure and function of PSII, the exact physiological function of Cyt b 559 remains unclear. Cyt b 559 is not involved in the primary electron transfer pathway in PSII but may participate in secondary electron transfer pathways that ...

In this project, I have studied the performance gain of MIMO systems. There are two types of gain provided by the MIMO channels: one measures the increase of the capacity by the number of degrees of freedom of the channel (spatial multiplexing gain), and the other improvement of the reliability by the diversity gain. Most of previous works focus on either one of these two types of gain by desig...

In this paper, we present a group pattern mining approach to derive the grouping information of mobile device users based on a trajectory model. Group patterns of users are determined by distance threshold and minimum time duration. A trajectory model of user movement is adopted to save storage space and to cope with untracked or disconnected location data. To discover group patterns, we propos...
