objective and aims intrauterine devices (iuds) are placed in the uterine cavity with the objective of providing long-term contraception, mainly by preventing fertilization. in this research has been tried to show that method of iud insertion is effective to decrease complications’ incidence . rotating withdrawal technique is presenting, has been using for this purpose. design and setting this h...

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...

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...

To generate high quality synchrotron radiation in the future ERL light sources, the performance of the ERL injector, which has critical components, a photo cathode gun and super conducting cavities, is very important. In the injector, an electron beam is generated by photo cathode DC gun, and accelerated by super conducting RF cavities. Since an electron beam with −77 pC bunch charge and 1.3 GH...

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...
