Sensitivity of CO₂ Flow in Production/Injection Wells in CPG (CO₂ Plume Geothermal) Systems by Sofianos Panagiotis Fotias, Vassilis Gaganis

“…Moreover, the thermosiphon effect, owned to the significant change of fluid density between the injection (cold) and the production wells (hot) as well as to its change along the wells, significantly reduces the need for pumping, hence the operating costs. …”

The effects of a dopamine agonist (apomorphine) on experimental and spontaneous pain in patients with chronic radicular pain: A randomized, double-blind, placebo-controlled, cross-... by May Haddad, Dorit Pud, Roi Treister, Erica Suzan, Elon Eisenberg

“…<h4>Results</h4>One-hundred and twenty minutes following apomorphine (but not placebo) injection, cold pain threshold and tolerance in the hand increased significantly compared to baseline (from a median of 8.0 seconds (IQR = 5.0) to 10 seconds (IQR = 9.0), p = 0.001 and from a median of 19.5 seconds (IQR = 30.2) to 27.0 seconds (IQR = 37.5), p<0.001, respectively). …”

Study of Cooling Characteristics of Axisymmetric Tail Nozzle by Hao Zeng, Rui Xi, Yiwen Li, Xingyao Hou, Changqin Fu

“…When the flow rate of the injected cold stream was increased by 4%, the intensity of the infrared radiation from the nozzle was reduced by 52.6%, 55.8%, and 66.2% for the injected air, liquid nitrogen, and dry ice cold streams, respectively.…”

Failure Behavior of Hot-Dry-Rock (HDR) in Enhanced Geothermal Systems: Macro to Micro Scale Effects by Hongwei Zhang, Zhijun Wan, Derek Elsworth

“…Specifically, the length of micro-cracks in the granite at 300 °C could be 10 times longer okthan that at 200°C. Quenching or injecting cold water into HDRs would further weaken the rock and induce thermal damage to the rock structure. …”

Effects of phase-transition heat on fracture temperature in self-propping phase-transition fracturing technology by Nanlin ZHANG, Fushen LIU, Liangliang JIANG, Zhifeng LUO, Yiwen JU, Pingli LIU, Liqiang ZHAO, Yuxin PEI

“…The study indicates that, at different positions and times, the cooling effect of the injected cold fluid and the exothermic effect during the phase transition alternately dominate the temperature within the fracture. …”
