A complete nucleotide sequence of the new Pseudomonas aeruginosa Luz24likevirus phiCHU was obtained. This virus was shown to have a unique host range whereby it grew poorly on the standard laboratory strain PAO1, but infected 26 of 46 clinical isolates screened, and strains harboring IncP2 plasmid pMG53. It was demonstrated that phiCHU has single strand interruptions in its genome. Analysis of the phiCHU genome also suggested that recombination event(s) participated in the evolution of the leftmost portion of the genome, presumably encoding early genes.

Stephen B. Dobranski, Milton Quarterly 49.3 (October, 2015), 181-4:

'By addressing classical and neo-Latin works with which Milton's poems appear to engage, Haan has pursued something unattempted yet. Her erudite and engaging commentary on the Poemata is the most extensive and impressive that I have encountered in any edition ... Haan's discussion of Milton's Poemata - including the Testimonia, the one Italian and four Latin encomia by the poet's acquaintances published in 1645 and 1673 - is remarkably detailed and well-researched. In these sections, readers learn, for example, how Milton's Epitaphium Damonis borrows from both classical writers (Theocritus, Moschus) and contemporary models (Castiglione, Zanchi) while transcending all of them through a pattern of resurrection motifs. Or, readers can discover affinities between Milton's lament on the death of the Bishop of Ely and a poem by the Italian humanist Hieronymo Aleander, Jr., or learn about the connections between Milton's Elegia Quinta and George Buchanan's Maiae Calendae ... The Shorter Poems is a scholarly achievement of the highest order.'

Noam Reisner, Review of English Studies 65 (2014), 744-5:
‘Haan shines with her Neo-Latinist expertise by offering a vivid separate introduction to the Latin poems, which sets up Milton’s poemata specifically within the Neo-Latin contexts of the seventeenth century, thereby dispelling any remaining view of these poems as juvenilia (a view which results from reading the poems chronologically). … The present volume will instantly establish itself as the definitive resource for any reader interested in Milton’s shorter poems, and it is scarcely imaginable that it will ever be eclipsed or be in need of replacing. Its contribution is important in all areas, especially in providing for the first time in a single volume truly valuable documents which can teach us a lot more about Milton’s poetic development than simply reading the poems in chronological sequence. But perhaps, this edition’s greatest achievement is the way in which it succeeds in giving Milton’s Latin poems the pride of place they have long deserved as fully integral to Milton’s complete poetic imagination. Haan’s specific achievement in this regard is less in updating the translations than in providing a different context through which to look at the Latin poems themselves. Haan’s detailed commentaries set the Latin poems in a completely fresh light which looks beyond the obvious classical references and allusions, noted by Carey and many other editors, to Milton’s complex engagement with the Neo-Latin literary culture of his time. It is this aspect of the volume, more than anything else, which vindicates its essentialness.'

It is crucial to develop a catalyst made of earth-abundant elements highly active for a complete oxidation of methane at a relatively low temperature. NiCo2O4 consisting of earth-abundant elements which can completely oxidize methane in the temperature range of 350-550 °C. Being a cost-effective catalyst, NiCo2O4 exhibits activity higher than precious-metal-based catalysts. Here we report that the higher catalytic activity at the relatively low temperature results from the integration of nickel cations, cobalt cations and surface lattice oxygen atoms/oxygen vacancies at the atomic scale. In situ studies of complete oxidation of methane on NiCo2O4 and theoretical simulations show that methane dissociates to methyl on nickel cations and then couple with surface lattice oxygen atoms to form -CH3O with a following dehydrogenation to -CH2O; a following oxidative dehydrogenation forms CHO; CHO is transformed to product molecules through two different sub-pathways including dehydrogenation of OCHO and CO oxidation.

The introduction outlines the notion of urban space and crisis in Europe while taking into account the more recent protests and riots in different cities, in and beyond Europe. It is argued that the phenomen of protest is happening alongside the economic crisis underscoring an alternative political public civic spirit expressing to a certain degree the renaissance and timely making of, what might be called in the digital age, #œuvre. Its forces and emotional properties capture a political realm that unfolds as a globalized urban transnational public space, still progressing. Further, it introduces the collection of papers for the special themed feature. Five papers look at affective practices through a Continental European lens, which places the meaning of race, migration and intersecting identity angles at the centre of debates of individual encounters in public spaces. The final and sixth paper, written by Brenda Yeoh, looks through a Singapore/East Asia lens, and comments on the common European threats as well as on the historical specificity and implications of distinctive geo-political spaces for affective practices.

In times of globalisation and super-mobility, ideas of normality are in turmoil. In different societies in, across and beyond Europe, we face the challenge of undoing specific notions of normality and creating more inclusive societies with an open culture of learning to live with differences. The scope of
the paper is to introduce some findings on encounters with difference and negotiations of social values in relation to a growing visibility of difference after 1989 in Poland, on the background of a critique of normality/normalisation and normalcy.On the basis of interviews conducted inWarsaw, we investigate how normality/normalisation discourses of visible homosexuality and physical disability are incorporated into individual self-reflections and justifications of prejudices (homophobia and disabilism). More specifically we argue that there are moments of ‘cultural transgressions’ present in everyday practices towards ‘visible’sexual and (dis)ability difference.
