Almost all the electricity currently produced in the UK is generated as part of a centralised power system designed around large fossil fuel or nuclear power stations. This power system is robust and reliable but the efficiency of power generation is low, resulting in large quantities of waste heat. The principal aim of this paper is to investigate an(More)
Isolated rat hepatocytes responded to a variety of Ca2+-mobilizing agents (vasopressin, angiotensin II, epinephrine, epidermal growth factor, ATP, and ADP) with a rapid increase in phosphatidate mass, as measured by a sensitive new method. When hepatocytes were incubated with vasopressin (10(-8) M), phosphatidate levels increased 2-3-fold in 2 min, but(More)
The design for the Next Linear Collider (NLC) at SLAC is based on two 11.4 GHz linacs operating at an unloaded acceleration gradient of 50 MV/m increasing to 85 MV/m as the energy is increased from 1/2 TeV to 1 TeV in the center of mass[1]. During the past several years there has been tremendous progress on the development of 11.4 GHz (X-band) RF systems.(More)
The linacs proposed for the Next Linear Collider (NLC) and Japanese Linear Collider (JLC) would contain several thousand X-Band accelerator structures that would operate at a loaded gradient of 50 MV/m. An extensive experimental and theoretical program is underway at SLAC, FNAL and KEK to develop structures that reliably operate at this gradient. The(More)
The Binary Pulse Compression system installed at SLAC was tested using two klystrons, one with 10 MW and the other with 34 MW output. By compressing 56@ ns klystron pulses into 70 ns, the measured BPC output wss 175 MW, limited by the available power from the two klystrons. This output was used to provide 10GMW input to a 36cell X-band structure in which a(More)
Ouabain-sensitive 86Rb+ uptake by isolated rat hepatocytes was studied to elucidate how Ca2+-mobilizing hormones stimulate the Na+-pump. Stimulation of this uptake was observed with concentrations of vasopressin ([8-arginine]vasopressin, AVP), angiotensin II, and norepinephrine which elicited Ca2+ mobilization and phosphorylase activation. These results(More)
The Central Outer Tracker is a large cylindrical drift chamber constructed to replace CDF’s original central drift chamber for the higher luminosity expected for Run 2 at the Fermilab Tevatron. The chamber’s drift properties are described in the context of meeting the operating requirements for Run 2. The design and construction of the chamber, the(More)
The final focus of the Next Linear Collider (NLC) demagnifies electron and positron beams of 250-750 GeV energy down to a transverse size of about 2.5 x 350 nm2 at the interaction point (IP). The basic layout, momentum bandwidth, vibration tolerances, wakefield effects, and the tunability of the proposed final focus design are discussed. Also a perspective(More)
The SLAC electron-positron colliding-beam project SPEAR was completed and stable colliding beams were achieved in April, 1972, after a construction period of approximately 20 months. Since that time, an active experimental high-energy physics program has begun in addition to a program of continued studies of accelerator physics. This paper discusses only(More)
The aim of this study was to test the feasibility of a software application that would allow the anonymization and cataloguing of whole DICOM datasets in order to build searchable radiology museums within PACS. The application was developed on a dedicated networked PC, using C# and HL7 coding. Whole DICOM datasets were pushed from PACS to a networked PC on(More)
