One of the major factors in the nitrogen metabolism of animals is the phenomenon of protein turnover i.e. the continual breakdown and synthesis of body protein, the resultant of which is protein deposition. The measurement of these processes has consequently attracted much interest although, for reasons of technique, attention has focused upon measurements of protein synthesis, protein breakdow...

-Chlorite-mica stacks (grains of intergrown chlorite and white mica) in a matrix of fine-grained white mica and chlorite have been studied using XRD, SEM, EMPA, TEM and AEM methods. The stacks occur in a weakly cleaved Llandoverian mudstone, central Wales, which has a white mica (illite) crystallinity index of 0.35 ° A20 corresponding to the lower anchizone. White mica occurs as packets (100/~ ...

Monotonic convergence is established for a general class of multiplicative algorithms introduced by Silvey et al. (1978) for computing optimal designs. A conjecture of Titterington (1978) is confirmed as a consequence. Optimal designs for logistic regression are used as an illustration.

The classical global criteria for the existence of Hamilton cycles only apply to graphs with large edge density and small diameter. In a series papers Asratian Khachatryan developed local in finite connected graphs, which are analogues due Dirac (1952), Ore (1960), Jung (1978), Nash-Williams (1971). idea was show that concept Hamiltonicity can, under rather general conditions, be captured by ph...

the lowest among all racial and ethnic groups in the United States. From 1978 to 1991, smoking rates declined for both males and females in this group (Bachman et al., 1991). The Monitoring the Future (MTF) study showed that in 1978, 24.9 percent of African American high school seniors had smoked a cigarette daily, whereas only 4.1 percent reported this activity in 1991 (Johnston et al., 1996)....
