Mephedrone injecting has recently been reported in Romania, Slovenia, Guernsey and Ireland. The research reported here aimed to describe the experiences of a group of Irish injecting drug users, who were injecting mephedrone based headshop products prior to the introduction of legislative controls in Ireland, with particular focus on pre- and post ...

In the frame of the LYRA Program, funded by the Italian Space Agency, the LM-10-MIRA engine has been successfully tested. The engine has a vacuum thrust of 10-tons and has been developed by a joint Avio-KBKhA propulsion team in the frame of a dedicated ASI-Roscosmos inter-agencies agreement. After the experimental test campaign, further improvement for

Effects of Coiled Tubing Injector Head Abrupt Stop on the Coiled Tubing Strings
SPE/ICoTA Well Intervention Conference and ExhibitionAbstract This paper investigates the mechanical consequences of abrupt stops of coiled-tubing (CT) injector-head movement during heavy-pipe running-in-hole (RIH) operations. The objective is to quantify the transient dynamic loads produced during abrupt deceleration events, correlate those events with field-observed longitudinal plow ...

The flame tube head design is presented of the multi-injector combustion chamber of the gas turbine engine. The technique is described of determining the temperature of fuel gas flowing in the header, which is placed in the combustion chamber flame tube head. The calculation results of the fuel heating in the flame tube head are given.

Resolving Rigless ESP Deployment Challenges Using a Modified Coiled Tubing Injector Head
SPE Middle East Artificial Lift Conference and ExhibitionAbstract Electric Submersible Pumps (ESPs) are conventionally rig-deployed via production tubing, with clamped-on power cable. The long wait and installation times incur high operating expenses, with large surface and carbon footprints. Riglessly-deployed, permanent ESP systems address the above limitations, but challenges include safe ...

This paper reports on the repetitive laser ignition by optical breakdown within an experimental rocket combustion chamber. Ignition was performed by focusing a laser pulse generated by a miniaturized diode-pumped Nd:YAG laser system. The system, which delivers 33.2 mJ in 2.3 ns, was mounted directly to the combustion chamber.
