In 5 dogs which ingested 25 or 50 ml. of D20 with one daily meal, maximal plasma concentrations of tracer were reached in 12-24 hr. The disappearance rate during 14 days was exponential, confirming studies of others in humans. Water turnover, calculated from values obtained for body water and the disappearance rates, agreed well with total water intake, which included water taken as such and th...

JEL Classification: D20. Supply Chain Collaboration (SCC) is still a new definition in Vietnam, where a small number of enterprises formed or participated in supply chains. This leads to the need of a distinct study, depict the real situation of supply chain and especially SCC in Vietnam. The purpose of this study is to examine the feasibility of a collaboration index based on previous findings...

The fiber shaft of human adenoviruses (HAdVs) is essential for bringing the penton base into proximity to the secondary cellular receptor. Fiber shaft sequences of all 53 HAdV types were studied. Phylogeny of the fiber shaft revealed clustering corresponding to the HAdV species concept. An intraspecies recombination hot spot was found at the shaft/knob boundary, a highly conserved sequence stre...

We examine the dynamic formation and stochastic evolution of networks connecting individuals. The payoff to an individual from an economic or social activity depends on the network of connections among individuals. Over time individuals form and sever links connecting themselves to other individuals based on the improvement that the resulting network offers them relative to the current network....

The rise of barter and non-cash payments has become a dominant feature of the Russian transition to a market economy. This paper confronts with empirical evidence two approaches to explain barter in Russia: the ’illusion view’ and the ’trust view’ of barter. The ’illusion view’ suggests that barter allows the parties to pretend that the manufacturing sector in Russia is producing value added by...

A relatively stable specific complex of the chromatin core histones H2A, H2B, H3, and H4 has been obtained in 2 M NaCl/25 mM sodium phosphate buffer, pH 7.0. The histone core complex has an apparent specific volume of 0.73 ml/g. Its sedimentation coefficient was dependent on rotor speed (angular velocity, omega) and attained different stable values at low and high rotor speeds. The drop in sedi...

It is common to de…ne a network organization as one that is fast and ‡exible in adapting to changes in the underlying environment. But besides the short-run advantages of adaptability, fast changes in the structure of the organization can also be detrimental in the longer run. This happens because a widespread knowledge of the organization’s structure is important in channelling (and thus speed...

A threonine tRNA was purified from Bacillus subtilis W168 by a combined use of column chromatographic systems. The nucleotide sequence was determined to be pG-C-C-G-G-U-G-U-A-G-C-U-C-A-A-U-D-G-G-D(U)-A-G-A-G-C-A-A-C-U-G-A-C-U-mo5U-G-U-t6A-A-psi-C-A-G-U-A-G-m7G-U-U-G-G-G-G-G-T-psi-C-A-A-G-U-C-C-U-C-U-U-G-C-C-G-G-C-A-C-C-AOH, where about 40 % of D20 remained unmodified as U20. It consists of 76 n...

ETHODS FOR DETERMINATION of deuterium oxide (D00) using infrared spectrophotometry have been reported by a number of workers (1-3). These methods permit determination of D00 in biologic fluids with an accuracy and precision satisfactory for determination of total body water and similar problems. The use of an infrared spectrophotometer for measurement of 1)20 in water and biologic fluids offers...

The way people form groups when facing a coordination problem poses an interesting question. This paper addresses the issue of what type of clubs are formed when players must play a public goods game with the other players belonging to their club. I use a two-stage approach to separate network decisions and public goods decisions and apply farsighted stability to characterize the network struct...
