Oxalic acid undergoes enzymic transformation along diverse channels in cell-free preparations from micro-organisms and plants. In Collyvia veltepes oxalate undergoes a simple decarboxylation (Shimazono, 1955; Shimazono & Hayaishi, 1957), whereas in other micro-organisms the decarboxylation is preceded by the formation of the CoA derivative of oxalate (Jakoby, Ohmura & Hayaishi, 1956; Kimura, Ka...

Although schistosomiasis is a widespread infection in the tropics, travellers are almost exclusively infected in sub-Saharan Africa, through exposure to freshwater infested with cercariae of either Schistosoma mansoni (intestinal schistosomiasis) or Schistosoma haematobium (urinary schistosomiasis) [1]. Primary infection may cause a febrile hypersensitivity reaction occurring three to 12 weeks ...

We estimate elastic and anelastic parameters their evolution during laboratory rock deformation experiments, while developing a Monte Carlo waveform inversion. The transducer-to-transducer one-source one-station active seismic data of dry water-saturated samples are obtained from Zaima Katayama (2018), https://doi.org/10.1029/2018JB016377. first performed trial-and-error the boundary conditions...

Doxorubicin-overproducing strains of Streptomyces peucetius ATCC 29050 can be obtained through manipulation of the genes in the region of the doxorubicin (DXR) gene cluster that contains dpsH, the dpsG polyketide synthase gene, the putative dnrU ketoreductase gene, dnrV, and the doxA cytochrome P-450 gene. These five genes were characterized by sequence analysis, and the effects of replacing dn...

This paper presents explicit expressions for the mean sojourn times in a multi-stage tandem queue, with Poisson arrival and general service times, served by a s,ingle server with a cyclic switching rule, M/GI-G2-"'GN/l. The expressions are derived using the results of the two-stage tandem queue, M/GI-G2/1, already considered by some authors and the well-known Pollaczek-Khintchine formula. With ...

Perlick’s classification of (3 + 1)-dimensional spherically symmetric and static spacetimes (M, η = − 1 V dt + g) for which the classical Bertrand theorem holds [Perlick V 1992 Class. Quantum Grav. 9 1009] is revisited. For any Bertrand spacetime (M, η) the term V (r) is proven to be either the intrinsic Kepler– Coulomb or the harmonic oscillator potential on its associated Riemannian 3manifold...

Emittance growth due to intrabeam scattering (IBS) is a major limitation for high energy high density accelerators. The reachable maximum particle density depends strongly on how IBS can be compensated for by electron cooling (EC). Hence calculations of the growth rates of the horizontal and vertical emittances
̇h,v/ h,v and of the (longitudinal) momentum spread
̇ / due to IBS are necessary for...
