Prolonged (90 minutes) incubation with tumor promoter 12-O-tetnadecanoyl-phorbol-13-acetate (TPA) elicits the redistribution of zinc from the nuclear fraction and mitochondria to the cytosol and microsQmes in rabbit thymocytes. The zinc redistribution might play a role in the TPA-caused desensitization of T lymphocytes towards calcium and in the TPA-induced inhibition of GI--~ S phase transitio...

The material selection of injection gas wells in acid flooding is the bottleneck successful implementation technical scheme. Through standard and literature research, materials wellhead, wellbore, packer for reinjection well are preliminarily established, then suitable further screened by using weight-loss surface characterization method. Finally, a new type designed to optimize wellbore materi...

SUMMARY Electromagnetic methods are increasingly being applied in settings with steel infrastructure. These include applications such as monitoring of CO2 sequestration or even assessing the integrity a wellbore. In this paper, we examine impacts magnetic permeability steel-cased well on electromagnetic responses grounded source experiments. We consider vertical wellbore and simulate time frequ...

An unexpected and unwanted influx of gas or “kick” into the wellbore during hydrocarbon drilling can cause catastrophic blowout incidents, resulting in human casualties, ecological damage, asset losses. The ability oil industry to control kick depends on our accurately detect monitor migration a borehole real-time. This study demonstrates application optical fiber-based Distributed Acoustic Sen...

Injection of CO2 in geological reservoirs or deep aquifers is nowadays studied to regulate the global warming by limiting the amount of greenhouse gases emitted by human activity into the atmosphere. CO2 is captured from exhaust gas in power plants or industrial units and then stored in underground geological reservoirs. The experience available in the oil industry concerning CO2 injection clea...

structural health monitoring of cracked structures is one of beloved subject of researchers recently. consider of crack behavior in the water and energy pipeline is important because of environmental problems. in this paper consider of crack parameters in the underwater pipe subjected to mechanical transient load is investigated. for this purpose, three- dimensional parametric model of cracked ...

despite the mythology that the global economy with its trade rules creates a ‘level playing field,’ international trade has never involved ‘level players.’ the inequalities in outcomes generated by the more powerful winning more frequently has led to innovative ideas for ex post redistribution to make the matches between the players both fairer, and in the analogy to basketball used by the auth...
