The EVLG (European Veterinary Libraries Group) had a very nice meeting outside the conference centre on the grass(and in the shade!).We elected some new board members and the board is now:Chair: Michael Eklund, SwedenVicechair: Raisa Iivonen, FinlandSecretary: Fiona Brown, Great BritainWebmanager: Eva Orban, HungaryTreasurer: Derek Halling, USA
Report from the European Veterinary Libraries Group (EVLG)
The European Veterinary Libraries Group (EVLG) met in one of the University of Edinburgh Main Library meeting rooms, with a view over the Meadows. There were seventeen attendees from nine countries.Michael Eklund (Sweden), EVLG President reported that the Facebook pages and the EVLG homepage had improved the group’s communication over the last year
Report from the International Conference of Animal Health Information Specialists ICAHIS Satellite Day
The International Concerence of Animal Health Information Specialists (ICAHIS) held a Satellite meeting ahead of the joint EAHIL+ICAHIS+ICLC Workshop in June 2015. This brief report summarises the day and gives a synopsis of the presentation given by the invited speaker
Laser ablation for the synthesis of carbon nanotubes
Single walled carbon nanotubes are produced in a novel apparatus by the laser-induced ablation of moving carbon target. The laser used is of high average power and ultra-fast pulsing. According to various preferred embodiments, the laser produces and output above about 50 watts/cm.sup.2 at a repetition rate above about 15 MHz and exhibits a pulse duration below about 10 picoseconds. The carbon, carbon/catalyst target and the laser beam are moved relative to one another and a focused flow of "side pumped", preheated inert gas is introduced near the point of ablation to minimize or eliminate interference by the ablated plume by removal of the plume and introduction of new target area for incidence with the laser beam. When the target is moved relative to the laser beam, rotational or translational movement may be imparted thereto, but rotation of the target is preferred

Hydrodynamics of the Certas™ programmable valve for the treatment of hydrocephalus
<p>Abstract</p> <p>Background</p> <p>The new Certas™ shunt for the treatment of hydrocephalus has seven standard pressure settings that according to the manufacturer range from 36 to 238 mmH<sub>2</sub>O, and an additional “Virtual Off” setting with an opening pressure >400 mmH<sub>2</sub>O. Information on actual pressure response and reliability of shunt performance is important in clinical application, especially the “Virtual Off” setting as a non-surgical replacement for shunt ligation. The objective of this study was to evaluate the <it>in-vitro</it> hydrodynamic performance of the Certas™ shunt.</p> <p>Methods</p> <p>Six new Certas™ shunts with proximal and distal catheters were tested with an automated, computerized test system that raised the pressure from zero to a maximum pressure and back to zero at each valve setting. Opening pressure and flow resistance were determined.</p> <p>Results</p> <p>For settings 1–7 the measured opening pressure range was 26 to 247 mmH<sub>2</sub>O, and the mean change in opening pressure for a one-step adjustment was between 33 and 38 mmH<sub>2</sub>O. For setting 8 (“Virtual Off”) the measured mean opening pressure was 494 ± 34 mmH<sub>2</sub>O (range 451 to 556 mmH<sub>2</sub>O). The mean outflow resistance was 7.0 mmHg/ml/min (outflow conductance 17.9 μl/s/kPa).</p> <p>Conclusions</p> <p>The six shunts had similar characteristics and closely matched the manufacturer’s specifications for opening pressure at settings 1–7. The opening pressure for the “Virtual Off” setting was nearly 500 mmH<sub>2</sub>O, which is 100 mmH<sub>2</sub>O higher than the manufacturer’s specification of “>400” and should be functionally off for most patients with communicating hydrocephalus. Clinical studies are needed to evaluate if the CSF dynamic profile persists after implantation in patients.</p
Bayesian Multiple Emitter Fitting using Reversible Jump Markov Chain Monte Carlo
In single molecule localization-based super-resolution imaging, high labeling density or the desire for greater data collection speed can lead to clusters of overlapping emitter images in the raw super-resolution image data. We describe a Bayesian inference approach to multiple-emitter fitting that uses Reversible Jump Markov Chain Monte Carlo to identify and localize the emitters in dense regions of data. This formalism can take advantage of any prior information, such as emitter intensity and density. The output is both a posterior probability distribution of emitter locations that includes uncertainty in the number of emitters and the background structure, and a set of coordinates and uncertainties from the most probable model
