Five psychrophilic bacterial strains were isolated from soil samples collected above the treeline of alpine environments. Phylogenetic analysis based on 16S rRNA gene sequences indicated that these organisms represent four novel species of the genus Deinococcus; levels of sequence similarity to the type strains of recognized Deinococcus species were in the range 89.3-94.7 %. Strains PO-04-20-13...

The paper 3] was devoted to an extensive study of the interval of the lattice of semigroup pseudovarieties between the pseudovarieties O and PO generated by all semigroups of full and respectively, partial, order preserving transformations of a nite chain. It was shown that not only the interval O; PO] itself but also many of its naturally arising subintervals are huge in the sense that they al...

El Niño–Southern Oscillation (ENSO) and its relationships with marine environmental parameters comprise a very complicated and interrelated system. Traditional spatiotemporal techniques face great challenges in dealing with which, how, and where the marine environmental parameters in different zones help to drive, and respond to, ENSO events. Remote sensing products covering a 15-year period fr...

Drosophila ribosomal protein PO was overexpressed in Escherichia coli to allow for its purification, biochemical characterization and to generate polyclonal antibodies for Western analysis. Biochemical tests were originally performed to see if overexpressed PO contained DNase activity similar to that recently reported for the apurinic/apyrimidinic (AP) lyase activity associated with Drosophila ...

The interaction between POCl(3) or POBr(3) and pyridine or DMAP has been reinvestigated to clarify the discrepancies between previously published results concerning the Lewis acidity of phosphoryl halides and their behavior toward pyridine bases. The obtained results show that POCl(3) virtually does not react with pyridine, while it does with 4-(dimethylamino)pyridine (DMAP), even in SO(2) solu...

Five years ago, we highlighted Canada's emerging problem of prescription opioid (PO)-related harms and emphasized the need for targeted surveillance, research and interventions. Overall levels of PO use in the Canadian population have grown by 70% since then, while at the same time levels of non-medical PO use (NMPOU) in general and in key risk populations have continued to be high; furthermore...

Efficient numerical-asymptotic electromagnetic simulations of electrically large structures are presented based on an iterative hybridization of the method of moments (MoM) and physical optics (PO) in a higher order computational framework. The iterative MoM-PO technique employs multiple reflections between PO currents nested within an overall iterative MoM-PO multiple-reflection process. The r...

About 24 intrinsic neurosecretory neurons within the pericardial organs (POs) of the crab Carcinus maenas produce a novel crustacean hyperglycaemic hormone (CHH)-like peptide (PO-CHH) and two CHH-precursor-related peptides (PO-CPRP I and II) as identified immunochemically and by peptide chemistry. Edman sequencing and MS revealed PO-CHH as a 73 amino acid peptide (8630 Da) with a free C-terminu...
