Study on the Effect of the Water Injection Rate on the Cavern Leaching Strings of Salt Cavern Gas Storages

Energies, 2022
In the early construction of cavern leaching in salt cavern gas storages, the inner leaching tubing is often blocked, frequently leading to the bending deformation phenomenon of the leaching strings, which can result in out-of-control cavity shapes.

Reversal of pulmonary circulation

The Journal of Thoracic and Cardiovascular Surgery, 1975
The preliminary results and the technique of total reversal of the pulmonary circulation (RPC) are presented. Total RPC is technically feasible and not incompatible with life. It affords a new experimental model for in vivo study of pulmonary pathophysiology.

Detection of Tumor Cell-Specific mRNA in the Peripheral Blood of Patients with Breast Cancer-Evaluation of Several Markers with Real-Time Reverse Transcription-PCR [PDF]

, 2013
It is widely known that cells from epithelial tumors, e. g., breast cancer, detach from their primary tissue and enter blood circulation. We show that the presence of circulating tumor cells (CTCs) in samples of patients with primary and metastatic ...

Orthogonal experimental research on the structural parameters of a novel drill bit used for ice core drilling with air reverse circulation

Journal of Glaciology, 2019
A new type of ice core drill bit, designed with a vane swirler, was developed for ice core drilling with air reverse circulation. An orthogonal experimental design method was employed to investigate the effects of the swirler structure parameters on the ...

Spin-polarized vortices with reversed circulation

Physical Review A, 2022
We present the analysis of the structure of fermionic vortices with the spin-polarized core from a weak coupling limit to the unitary regime. We show the mechanism for the generation of the {\it reversed circulation} in the vortex core induced by an excess of majority spin particles.

Migration Characteristics of Boring Mud in Roadway Floor Anchor Wire Hole and Test in Coal Mine

Advances in Civil Engineering, 2021
Given the difficulty in drilling the anchor holes in the roadway floor of the coal mine, the characteristics of slag movement in the process of positive and negative circulation drilling are analyzed.

Ocean and atmosphere feedbacks affecting AMOC hysteresis in a GCM [PDF]

, 2016
Theories suggest that the Atlantic Meridional Overturning Circulation (AMOC) can exhibit a hysteresis where, for a given input of fresh water into the north Atlantic, there are two possible states: one with a strong overturning in the north Atlantic (on)

Experimental and numerical investigations on effect of reverse flow on transient from forced circulation to natural circulation

Nuclear Engineering and Technology, 2020
In a sudden shutdown of primary pump or coolant loss accident in a marine nuclear power plant, the primary flow decreases rapidly in a transition process from forced circulation (FC) to natural circulation (NC), and the lower flow enters the steam ...
