Despite wide use of terms such as "digital manufacturing" and "digital fabrication" in the constructional steel industry, actual use to date is mostly limited to research and development activities. In contrast, other heavy industries, such as automotive and aerospace have moved much faster and implemented many aspects of digital manufacturing and fabrication in product creation and traditional workflows. As a foil to the current state of the industry, this paper presents the erection, and disassembly of a simple, two‐storey frame that employs an alternative steel connection that can be manufactured using current plasma, laser, and water jet technologies, referred to as the intermeshed steel connection (ISC). The field demonstration described in this paper shows the connection's ability to reduce on site erection time, substantially reduce the number of site bolts, eliminate site welding, and allow for easy deconstruction. The connection has been under testing and development through a consortium of the University College Dublin, Queens University Belfast and, the University of Minnesota. [ABSTRACT FROM AUTHOR]

ABSTRACT The simultaneous firing of marine sources can provide a significant uplift in terms of acquisition efficiency and data quality enhancement. However, the seismic interference resulting from one or more 'other' sources needs to be well understood and the appropriate processing strategies need to be developed for the method to fulfil its promise. In this paper, a modified inversion approach is presented for the effective separation of sources in marine simultaneous shooting acquisition. The method aims to distribute all energy in the simultaneous shot records by reconstructing the individual shot records at their respective locations. The method is applied to a wide azimuth data set acquired in the Gulf of Mexico where two sources out of four in total were fired simultaneously. Results demonstrate that the individual sources can be separated satisfactory, both at the prestack and post-stack level. [ABSTRACT FROM AUTHOR]

Background: Report on a simple solution to allow programming of defibrillators in the presence of a Heartmate II (Thoratec Corporation, Pleasanton, CA, USA) ventricular assist device. Ventricular assist devices have become increasingly utilized for patients waiting for heart transplantation as well as those who will be maintained on a permanent support. The Heartmate II, which was recently given Food and Drug Administration approval as a bridge-to-transplant device, has a particular anomaly that complicates patient management. The pulse width modulator of the Heartmate II produces electromagnetic noise that interferes with the ability to interrogate and program certain defibrillators, and explantation of the defibrillator has been reported as the only viable solution. Methods: The authors describe the use of cast-iron pans to reduce the electromagnetic interference between St. Jude Medical's first-generation Atlas family of defibrillators (St. Jude Medical, St. Paul, MN, USA) and the Heartmate II pump. Results: The use of a simple shielding protocol avoids the need to remove a pre-existing defibrillator from a patient receiving support from the Heartmate II ventricular assist device. Conclusions: The method described herein is important as future generations of medical devices may present different types of device-device interactions. Simple bedside methods to eliminate interference can potentially help patients who would otherwise need one or another device removed [ABSTRACT FROM AUTHOR]

Abstract How far does the difference between a child's minimum reading entitlement (“I can read different types of text for different purposes – and I've got level 4 to prove it”) and maximum entitlement (“I recognise the power of literature and want to read it for the rest of my life”) encapsulate a tension present in many primary classrooms? In England, literature (poetry, narrative, plays) is taught as part of the National Literacy Strategy and a child's knowledge of how it works may be assessed if literary texts are included in the end of Key Stage 2 reading test. The requirements of the Strategy and especially the reading test may well impact on the maximum entitlement of a child to become a reader for life. This article explores some of the dangers which result from viewing the minimum entitlement as the maximum being aimed at in the classroom. [ABSTRACT FROM AUTHOR]

Experience with 407 transvenous ventricular finned pacing leads with a sintered porous-surfaced electrode is reported. A low complication rate was encountered: 97% of patients were free from lead-related complications. Four patients (1%) required re-operation; two for lead displacement, one for failure to sense spontaneous ventricular activity and one for exit block. A further patient developed exit block which resolved spontaneously. The vast majority of patients had low chronic stimulation thresholds; for example at six months after implantation, the mean threshold for a group of pacemakers with a pulse duration of 0.5 ms was 1.4 ± 0.7 V and for another group with a pulse duration of 0.8 ms it was 1.9 ± 0.7 mA. However, six patients developed a transient high stimulation threshold during the month after implantation, and a high threshold developed in another patient at five months and persisted. Mean acute stimulation and sensing thresholds were satisfactory: 0.7 ± 0.2 V at 0.5 ms pulse duration and 7.6 ± 2.4 mV, respectively. [ABSTRACT FROM AUTHOR]
