This paper reports the results of preparing alloy nanoparticles by mechanical grinding followed by filtration to sort the particles according to size. Although the long-term goal of this work is to prepare icosahedral quasicrystalline nanoparticles, the alloy used in this study is of Al65Cu25Fe15 composition and multi phases, under the assumption that the established procedure is applicable to future quasicrystalline nanoparticle fabrication. The obtained particle size and elemental information were investigated using scanning electron microscopy and energy dispersive x-ray spectroscopy. Problems with filter fragment fall-out and salt contamination were encountered and procedures to address the problems have been suggested and tested. The study is successful in obtaining alloy particles with reduced sizes.
Previously known to form only under high pressure synthetic conditions, here we report that the T′-type 214-structure cuprate based on the rare earth atom Tb is stabilized for ambient pressure synthesis through partial substitution of Pd for Cu. The new material is obtained in purest form for mixtures of nominal composition Tb1.96Cu0.8Pd0.2O4. The refined formula, in orthorhombic space group Pbca, with a = 5.5117(1) Å, b = 5.5088(1) Å, and c = 11.8818(1) Å, is Tb2Cu0.83Pd0.17O4. An incommensurate structural modulation is seen along the a axis by electron diffraction and high resolution imaging. Magnetic susceptibility measurements reveal long-range antiferromagnetic ordering at 7.9 K, with a less pronounced feature at 95 K; a magnetic moment reorientation transition is observed to onset at a field of approximately 1.1 T at 3 K. The material is an n-type semiconductor.
New paediatric cardiology trainees are required to rapidly assimilate knowledge and gain clinical skills to which they have limited or no exposure during residency. The Pediatric Cardiology Fellowship Boot Camp (PCBC) at Boston Children’s Hospital was designed to provide incoming fellows with an intensive exposure to congenital cardiac pathology and a broad overview of major areas of paediatric cardiology practice.
The PCBC curriculum was designed by core faculty in cardiac pathology, echocardiography, electrophysiology, interventional cardiology, exercise physiology, and cardiac intensive care. Individual faculty contributed learning objectives, which were refined by fellowship directors and used to build a programme of didactics, hands-on/simulation-based activities, and self-guided learning opportunities.
A total of 16 incoming fellows participated in the 4-week boot camp, with no concurrent clinical responsibilities, over 2 years. On the basis of pre- and post-PCBC surveys, 80% of trainees strongly agreed that they felt more prepared for clinical responsibilities, and a similar percentage felt that PCBC should be offered to future incoming fellows. Fellows showed significant increase in their confidence in all specific knowledge and skills related to the learning objectives. Fellows rated hands-on learning experiences and simulation-based exercises most highly.
We describe a novel 4-week-long boot camp designed to expose incoming paediatric cardiology fellows to the broad spectrum of knowledge and skills required for the practice of paediatric cardiology. The experience increased trainee confidence and sense of preparedness to begin fellowship-related responsibilities. Given that highly interactive activities were rated most highly, boot camps in paediatric cardiology should strongly emphasise these elements.
The spatial structure of the X-ray sky in the direction of the North Polar Spur was examined in two energy bands, the B band (0.10 - 0.18 keV) and the C band (0.15 - 0.28 keV). A model with two emitting regions, one local with unabsorbed emission, and the other more distant with emission partially absorbed by spatially varying amounts was investigated.
Using the distribution of atomic hydrogen as a measure of absorbing material, this model was used to predict the flux in the direction of the North Polar Spur. The predicted flux was compared to the data obtained from several sounding rocket flights. The derived flux was found to correlate well with the observed data.
At Bothal we saw the battle-axe with which Robert Ogle, the first baron, slew Sir Davy Dunbar in a single combat. Who wore the tod tail, that is, the fox tail, in his hat in token none durst encounter him.
Henry the third matching with Scotland, both of the kings met at the Bishop’s Palace in York, where the bishop bestowed three score beeves5 on them for a breakfast, all other charges being suitable thereto.
George Nevell, archbishop and brother to the earl of Warwick that carried a king on his sleeve, at his establishment in the see strewed a thousand yards of cloth, which reached from St James, from whence he passed to theminster, which was presently cut and divided by 10 the people. He spent three hundred quarters of wheat, as many tuns of ale and 104 tuns of wine, the fowl and all other provision coming to an equal rate.
The earl of Warwick was his steward and another earl his marshal, and he had four marshals more, all knights. The earls with all ceremony 15 served him.
He sat in estate by himself, and on his right hand sat beneath him three bishops, and on his left a duke and two earls.
Ben Jonson’s walk from London to Edinburgh has caught the imagination and provoked the curiosity of many since it was first mooted in June 1617, a year before he set off. The journey itself was not the adventure it might have been before the Union of the Crowns, but that a celebrated and, frankly, weighty poet should choose to attempt it on foot was certainly remarkable. Most importantly, the expedition produced the encounter between Jonson and William Drummond recalled in the latter’s notes of his guest’s conversation and opinions, or ‘informations’. The views, jests and anecdotes set down there illuminate Jonson’s poetic principles, his views of his contemporaries, and the account he chose to give of himself. They are particularly beguiling for allowing us to imagine that we are hearing Jonson speak off the record, as it were, and that we can catch his conversational tone even through Drummond’s editorial compressions and sometimes pursed lips. The Informations also provide us with glimpses of the journey itself, including Jonson’s irritation at being followed – mocked, he thought – by Taylor, and his purchase of a pair of shoes at Darlington, which he ‘minded to take back that far again’ (ll.514–15). Such snippets have been combined with a sparse patchwork of other sources to build up an outline picture of Jonson’s walk and his possible motives for undertaking it. We also know from Edinburgh records that Jonson was made a burgess of the city, and that a dinner was held there in his honour in September 1618. In his Pennyles Pilgrimage Taylor records meeting his fellow poet at the house of John Stewart in Leith, while Jonson’s correspondence with Drummond and a dedication inscribed in a book presented to a Scots courtier reveal the names of some of his other hosts. From such diverse and, in some cases, fragmentary sources, scholars such as David Masson, Ian Donaldson and James Knowles have crafted an intriguing picture of the king’s poet, at the height of his fame, comfortably berthed in the capital of James’s first realm in the autumn and winter of 1618–19.
He cries first, ‘horse, Lurg,’ then the dog leaps up before him, and there will sit upon the neck of the horse like an ape. Then he bids him ‘ga down sir, and make ye for’d,’ then he goeth piss and shit. Then he bids him cast for a fore gate of a night drift; then he leads him in a line of cord, and as soon as he sees him put down his head, he cries, ‘is that it? Chalice5 that.’ Then he barks. Then he cries, ‘chalice that, the caple, and the cawd arne’ (that is, the horse shoes) that drives the cow with it. ‘Turn tha woo’d. Go where she goes; put her tull a stall, and thous ha’ blood on her. Keep thee with thine awne cow and change her not. Is that she that tha first fand? Keep tha with that and change her not, but go where she10 goes. Shame, thief, he’ll shame’s both. Shame him that would shame thee and me.’
Then when he comes among other beasts he cries, ‘is tat hit, that tha first fand?’ It’s a night drift, and he waps it in the day fewte, that is, when other beasts crosseth the trod. Then when he is troubled with another15 trod, he cries, ‘hast it? Keep thee woo’t then. That’s thine awne bugle, i’faith tha gar’st thy bugle blaw now. Gather’t, gather’t, and go thy way wooth’t, and change not that.’
We set out of London on Wednesday the eight of July and reached that night to Tottenham High Cross, where we lodged at the Bear etc. By the way thither we met with the shake-rag errant and his two doxies etc.
From thence to Waltham, where my Lady Wroth came to my gossip etc. with Mr Ed Kerry, Mr Harbert and5 Mr Powell, etc. There also came to us two Cambridge men, one fellow of Q College called Holmes, and Blitheman Master of Art who etc.
Thence to Hogsdon, where a lunatic woman met us by the way and went dancing before us, and a humorous tinker of whom we could not be rid etc. There also three minstrels thrust themselves upon us, asking whether we would hear a merry song, which proved to be the life and death of my Lord of Essex. This forenoon it thundered and rained, which stopped us from setting forwards till towards the evening. Then we came to Ware, to Mr Cross’s, where Sir Robert Mansell, Sir Arnold Harbert, and Mr Rice came to us and Sir Thomas [sic] subscribed 10 pieces etc. Here my fat hostess commended me with a token. Thence to Puckeridge the Falcon, where we dined, where mine host Holland gave my gossip a forest bill etc. That night we came to Dick of Buntingford’s to bed.
In A Jovial Crew, perhaps his last play, Richard Brome presents an extraordinary picture of a gentleman given, in the strongest possible sense, to travel. Springlove is steward to the ‘ancient esquire’ Oldrents, charged with the responsibility of managing the latter’s substantial estate; when we first meet him he is encumbered with books and papers, ready to present to his master ‘a survey of all your rents / Receiv’d, and all such other payments as / Came to my hands since my last audit’ (1.1.123–5). Yet the efficiency with which he has calculated Oldrents’ income and expenditure is not a function of the pleasure he takes in his work; instead he is keen to complete his duties ten days early, around 25 April, so he can pursue his calling – figured in the play as the stirring song of nightingales and cuckoos, to which Springlove responds with a surge of emotion. He wants to travel, as he has been restrained from doing for the last year and a half – in fact, as he says, he needs to travel, and cannot be reasoned out of this drive:
’Tis the season of the year that calls me.
What moves her notes provokes my disposition
By a more absolute power of nature than
Philosophy can render an accompt for.
To Oldrents, rooted as he apparently is in his family lands, this is nothing more than a ‘disease of nature’, a ‘running sore’ or ‘gadding humour’, a worryingly pathogenic element in Springlove’s constitution (1.1.156, 175). But for his steward, this disposition is nothing less than the ‘predominant sway of nature…in me’ (1.1.242–3). It cannot be suppressed or denied, however suspect and unnatural it appears to those, like Oldrents, who wish only to cleave to their home country.
At the heart of this book is a previously unpublished account of Ben Jonson's celebrated walk from London to Edinburgh in the summer of 1618. This unique firsthand narrative provides us with an insight into where Jonson went, whom he met, and what he did on the way. James Loxley, Anna Groundwater and Julie Sanders present a clear, readable and fully annotated edition of the text. An introduction and a series of contextual essays shed further light on topics including the evidence of provenance and authorship, Jonson's contacts throughout Britain, his celebrity status, and the relationships between his 'foot voyage' and other famous journeys of the time. The essays also illuminate wider issues, such as early modern travel and political and cultural relations between England and Scotland. It is an invaluable volume for scholars and upper-level students of Ben Jonson studies, early modern literature, seventeenth-century social history, and cultural geography.
