SUMMARY Fault zones often serve as the major fluid pathways in a variety of geo-energy systems, such deep geothermal systems. However, injection-induced instability faults can sometimes lead to large-magnitude earthquakes. Cyclic injection has thus been proposed an alternative protocol better manage and mitigate associated seismic risks. The risks seismicity depend primarily on extent magnitude...

introduction lidocaine plus epinephrine is the most common anesthetic drug used in dentistry which has important cardiovascular side-effects like increase in blood pressure and cardiac arrhythmia. the goal of this study was to evaluat cardiovascular effects of one cartridge of 2% lidocaine + 1:80000 epinephrine. methods and materials 60 cases without any systemic diseases who had been admitted ...

Experiments were conducted to evaluate the performance of a high grade low heat rejection (LHR) diesel engine with air gap insulated piston, air gap insulated liner and ceramic coated cylinder head [ceramic coating of thickness 500 microns was done on inside portion of cylinder head] with different operating conditions [normal temperature and pre-heated temperature] of crude pongamia oil (CPO) ...

A new fracture-injection/falloff type-curve analysis method is presented for reservoirs containing slightly compressible and compressible fluids. Type-curve analysis augments conventional beforeand after-closure methods, which are also reformulated in terms of adjusted pseudopressure and adjusted pseudotime to account for compressible reservoir fluids. Unlike beforeand after-closure methods whi...

lumbar puncture is one of the most common methods for assessment of central nervous system. allen is illustrating the role of nurses in relation to probable fears about this technique. question: what is lumbar puncture? answer: this technique is proper method that one needle and trocar enter to subarachnoid space in lumbar spine. this method is most common diagnostic test for central nervous sy...

Objective To investigate the clinical feasibility of the injection test for balloon placement during oesophageal pressure measurement in patients without spontaneous breathing. Methods The injection test was performed in 12 mechanically ventilated patients under deep sedation and paralysis. During withdrawal of the balloon from the stomach and air injection into the gastric lumen of the cathete...

Experiments were carried out to evaluate the performance of a medium grade LHR diesel engine consisting of air gap insulated piston with 3-mm air gap, with superni (an alloy of nickel) crown and air gap insulated liner with superni insert with different operating conditions of jatropha oil in crude from and biodiesel form with varied injection timing and injection pressure. Performance paramete...

[1] Over 109 small earthquakes (Mw 0.4–3.9) were detected during January 2011 to February 2012 in the Youngstown, Ohio area, where there were no known earthquakes in the past. These shocks were close to a deep fluid injection well. The 14 month seismicity included six felt earthquakes and culminated with aMw 3.9 shock on 31 December 2011. Among the 109 shocks, 12 events greater than Mw 1.8 were...
