The goal of this internal report is to summarize the experiences with the fault injector based on the Unix ptrace function. It should be explained how to use the fault injector for special experiments and how to interpret the results. In the first chapter (" ptrace(2) Interface ") an overview on the facilities of the Unix ptrace interface is given to see what faults/errors may be simulated by t...

It is well established that spray characteristics from automotive injectors depend on, among other factors, whether cavitation arises in the injector nozzle. Bulk cavitation, which refers to development distant walls and thus far streamline curvature associated with salient points on a wall, has not been thoroughly investigated experimentally nozzles. Consequently, it clear what causing this ph...

We are constructing a 1.2 kA, 1 MeV, electron induction injector as part of the RTA program, a collaborative effort between LLNL and LBNL to develop relativistic klystrons for Two-Beam Accelerator applications. The RTA injector will also be used in the development of a high-gradient, low-emittance, electron source and beam diagnostics for the second axis of the Dual Axis Radiographic Hydrodynam...

Background The incidence of systemic allergic reactions in the UK continues to rise. Appropriate and timely use of an adrenaline auto-injector is life saving. Anaphylaxis guidelines specify that individuals at high risk carry an adrenaline auto-injector at all times and receive adequate instruction on its use. We examined whether adult patients prescribed an adrenaline auto-injector had been gi...

Stimulated by state-of-the-art robotic and computer technology, Intra Cytoplasmic Sperm Injection (ICSI) automation aims to scale and seamlessly transfer the human hand movements into more precise and fast movements of the micro manipulator. Piezo-drill cell injection, a novel technique using piezo-driven pipettes with a very small mercury column, has significantly improves the survival rates o...

Results 724 teachers (8%) completed the survey. 48% had at least one student under their direct supervision with a severe allergy. 28% believed that all students with severe allergies had a management plan for treatment. 18% never reviewed this plan. More than 80% were confident in recognizing and knowing what to do for a severe reaction, and in using an epinephrine auto-injector. Teachers lear...

PURPOSE We describe an inexpensive, simple, and effective endothelium-Descemet membrane (EDM) graft injector assembled from regular operating room supplies in Descemet membrane endothelial keratoplasty (DMEK). METHODS To assemble the injector, standard intravenous tubing was cut approximately 2 inches from the Luer lock end, leaving a steep bevel. The cut end of the tubing was firmly wedged b...

Venturi injector is widely used in fertigation system due to its obvious advantages such as cheap and robust system without mobile pieces, simple structure, convenient to operation, stable performance, needless of external energy for operation etc. At present, the hydraulic parameters such as suction capacity (injection rate) for the most of the Venturi injectors produced domestically are not v...

The Large Hadron Collider (LHC) at CERN is at a very advanced stage of hardware commissioning and the first beam collisions in the experiments are expected during the year 2008. In line with the recommendations issued in 2006 by the European Strategy Group for Particle Physics, work has now started for maximizing the physics reach of the LHC and for preparing for other foreseeable needs. Beyond...
