New techniques based on Exceptional Field Theory have recently allowed for the calculation of Kaluza-Klein spectra certain AdS$_4$ solutions $D=11$ and massive IIA supergravity. These are that consistently uplift $S^7$ $S^6$ from vacua maximal four-dimensional supergravity with SO(8) ISO(7) gaugings. In this paper, we provide complete spectrum five such solutions, all them ${\cal N}=1$. preserv...

Functionally active 70S ribosomes containing 4-thiouridine (s4U) in place of uridine were prepared by a formerly described in vivo substitution method. Proteins were crosslinked to RNA by 366 nm photoactivation of s4U. We observe the systematic and characteristic formation of 30S dimers; they were eliminated for analysis of RNA-protein crosslinks. M13 probes containing rDNA inserts complementar...

A differentiate manifold M is said to be parallelizable if the tangent vector bundle of M is trivial. A topological manifold M is said to be topologically parallelizable if the tangent microbundle of M is trivial. In [2] Milnor has shown that on some open set M in some Euclidean space Rn there exists a differentiable structure with respect to which the integral Pontrjagin class p(M) of M is dif...

A chemical mutagenesis technique was employed for development of mutant strains of Sparassis crispa targeting the shortened cultivation time and the high β-glucan content. The homogenized mycelial fragments of S. crispa IUM4010 strain were treated with 0.2 vol% methyl methanesulfonate, an alkylating agent, yielding 199 mutant strains. Subsequent screening in terms of growth and β-glucan content...

The larva of Epigomphus crepidus Kennedy is described and figured and compared with other described congeners. It is characterized by 3rd antennomere spindle-shaped, flattened dorso-ventrally, twice longer than its widest part; ventral pad of hypopharynx pentagonal; prementum subrectangular, with lateral margins slightly convex on apical 0.60; ligula very poorly developed, with a ventral row of...

Certain mutations isolated in the 5' untranslated region (5'UTR) of the chloroplast rps7 gene in Chlamydomonas reduce expression of reporter genes. Second site suppressors in this 5'UTR sequence restore reporter expression. 5'UTR sequences with the original mutations fail to bind a 20-kD protein, one of five proteins that bind to leaders of several chloroplast genes. However, 5'UTRs from suppre...
