We show that the leptogenesis is automatic within the supersymmetric standard model if there exist right-handed neutrinos with mass less than Hinf , the expansion rate during the inflation. Its scalar component grows during the inflation due to the quantum fluctuation, oscillates coherently after the inflation, and its decay generates lepton asymmetry. The scenario is naturally embedded into SO...

The construction of plasmids containing T7 class I promoters with deletion mutants was described. Restriction fragments, ending at the Hinf I site located at position -10 in the promoter from 14.8% of the T7 genome, were cloned into pBR322. This produced the deletion of either the left or the right part of the promoter. The in vitro transcription properties of these plasmids were determined. Co...

Calf satellite DNA I (p = 1.715) has been hydrolysed by a number or restriction endonucleases. It consists of a repeating unit of 1460 nucleotide pairs within which the sites of Eco R II Mbo I, Sac I, Alu I, Ava II and Hha I were localised in comparison with those of Eco R I and Hind II. The distribution of the Hpa II, Sac I, Hha I, Hinf I and Mbo II sites within calf satellite DNA I, as well a...

In order to associate virulence in Neisseria gonorrhoeae with an alteration of the nucleotide sequence of its small covalently closed plasmid, plasmid deoxyribonucleic acid was isolated from both virulent (T1) and avirulent (T3) morphological types for two strains. Electrophoretic and contour length measurements of intact plasmids indicated a homogeneous population with a molecular weight of ap...

mtDNA restriction analysis has been carried out with 45 different commercial Saccharomyces wine yeast strains. The analysis with Hinf I provided unique profiles for 17 of the 45 strains and can therefore be considered as individual strains. Nevertheless, among the remaining 28 strains, only eight mtDNA restriction patterns appeared. These strains were subjected to electrophoretic karyotyping an...

String and M-theory compactifications generically have compact moduli which can potentially act as the QCD axion. However, as demonstrated here, such a compact modulus can not play the role of a QCD axion and solve the strong CP problem if gravitational waves interpreted as arising from inflation with Hubble constant Hinf > ∼ 10 GeV are observed by the PLANCK polarimetry experiment. In this cas...

Thirty clones derived from twenty isolates of heterotrophic nanoflagellates originating from a variety of marine and freshwater environments were examined by restriction fragment length polymorphism analysis of small subunit ribosomal RNA genes amplified by the polymerase chain reaction (riboprinting). The data were compared with light and electron microscopical identification of the isolates. ...
