The genes encoding the ribosomal P-proteins CcP0, CcP1 and CcP2 of Ceratitis capitata were expressed in the conditional P0-null strains W303dGP0 and D67dGP0 of Saccharomyces cerevisiae, the ribosomes of which contain either standard amounts or are totally deprived of the P1/P2 proteins, respectively. The presence of the CcP0 protein restored cell viability but reduced the growth rate. In the W3...

The possibility of separating ascites tumor cells with different numbers of chromo somes by means of counter-streaming centrifugation has been studied with the hy perdiploid Ehnlich ascites tumor (ELD) and its hypertetraploid offshoot (ELT). From ELD a fraction significantly higher in deoxyribonucleic acid phosphorus (DNAP) per cell than the unfractionated suspension was obtained. Inoculated in...

An issue that covers the tiny — the chromo­ somes of m alaria -carry ing mosquitoes — to the massive — the two bil­ lion peop le th o u g h t to be §ee Also affected with the tuberculo­ sis virus — will take center stage for seven panelists in th e N o tre D am e F o ru m today. The second annual forum, entitled “The Global Health Crisis: F o rg in g S o lu tions , Effecting C hange ,” will be ...

Considering some important classes of generalized coherent states known in literature, we demonstrated that all of them can be created via conventional fashion, i.e. the ”lowering operator eigen-state” and the ”displacement operator” techniques using the ”nonlinear coherent states” approach. As a result we obtained a ”unified method” to construct a large class of coherent states which already h...

suicide is a well-known public health problem in the united states. macroeconomic conditions, among many other factors, because of their impacts on psychological well-being of individuals, are thought to be linked to suicide attempts. however, previous research on the relationship between suicide rates and macroeconomic conditions, especially that of labor market conditions, has resulted into a...

In this paper we consider some systems of ordinary differential equations which are related to coagulationfragmentation processes. In particular, we obtain explicit solutions of such systems which involve certain coefficients obtained by solving a suitable algebraic recurrence relation. The coefficients are derived in two relevant cases: the high-functionality limit and the Flory-Stockmayer mod...

We will prove certain general relations in Matrix Product Ansatz for one dimensional stochastic systems, which are true in both random and sequential updates. We will derive general MPA expressions for the currents and current correlators and find the conditions in the MPA formalism, under which the correlators are site-independent or completely vanishing. We will also introduce an associative ...

We construct a displacement operator type nonlinear coherent state and examine some of its properties. In particular it is shown that this nonlinear coherent state exhibits nonclassical properties like squeezing and sub-Poissonian behaviour.
