Structure and properties of magnesium silicate borate melts glasses were investigated by using newly parameterized interaction potentials in molecular dynamics simulations compared with those calcium borate. The competition between the depolymerization silica network formation new bonds modifier ions leads to enhancement elastic moduli increasing content alkaline earth glasses. Compared silicat...

The Roseophages, a group of marine viruses that uniquely infect the Roseobacter clade of bacteria, play a significant role in marine ecosystems. Here we present a complete genomic sequence of an N4 phage 'vB_DshP-R1', which infects Dinoroseobacter shibae DFL12, together with its structural and genomic features. vB_DshP-R1 has an ~ 75 nm diameter icosahedral structure and a complete genome of 75...

The phage T4Dam and EcoDam DNA-[adenine-N6] methyltransferases (MTases) methylate GATC palindromic sequences, while the BamHI DNA-[cytosine-N4] MTase methylates the GGATCC palindrome (which contains GATC) at the internal cytosine residue. We compared the ability of these enzymes to interact productively with defective duplexes in which individual elements were deleted on one chain. A sharp decr...

The method of Cooke (1996) and Punt Butterworth (1999) for computing abundance estimates bowhead whales the BeringChukchi-Beaufort Seas stock is reviewed. These are computed from N4 number that passed within 4km visual range observation ‘perch’ which counted, estimated proportions P4 this standard errors (SE) P4. Errors discovered while assembling data used in developing previous were corrected...
