The Influence of the Extension Length of the Testing String on the Liquid Carrying Efficiency

Shiyou jixie, 2020
In the open-hole testing, the optimal testing string extension length is difficult to determine. Improper testing string extension length will cause problems such as long deliquification time and fluid accumulation in the bottom hole. For this reason, an

Evolution of FLRW spacetime after the birth of a cosmic string

, 2012
We consider the evolution of an initially FLRW universe after the formation of a long, straight, cosmic string with arbitrary tension and mass per unit length.

Modifying Glucose Metabolism Reverses Memory Defects of Alzheimer's Disease Model at Late Stages

Advanced Science, EarlyView.
Using spatial transcriptomics, we show that ferul enanthate (SL‐ZF‐01) reverses episodic‐like memory deficits in aged, but not young, Alzheimer’s disease (AD) mice. SL restores glucose metabolism and Glucose Transporter 1/3 expression via an ‘Aging‐AD‐Rescue’ pattern, rescuing deficits seen in aged AD mice.

Can cosmic strings generate large-scale streaming velocities?

The Astrophysical Journal, 1988
A detailed calculation is presented of the generation of large-scale streaming velocities by nonsuperconducting cosmic strings. A spherical infall model is used to calculate the peculiar velocity induced by an individual loop of cosmic string at rest in the comoving frame.

Enhancing the Ultrasonic Welding of Wood Using 3D Printed Lignin Energy Directors

Advanced Science, EarlyView.
Sustainable manufacturing for lightweight structures using ecofriendly materials will be key to reducing material consumption and lowering carbon footprints. Here, an approach is presented to weld wood using ultrasonic vibrations with material at the joint interface to direct energy.

The Use of Coiled Tubing as a Velocity String [PDF]

Acta Montanistica Slovaca, 2004
Liquid loading is a problem in many gas wells especially older and depleted type reservoirs. If steps are not taken to minimize this effect, it will severely limit the production or even "kill" the well.

Bioinspired Twisted Artificial Muscles with Enhanced Performance for Underwater Applications

Advanced Science, EarlyView.
A climbing plant‐inspired twisted artificial muscle (TAM) with a braided configuration and seal‐inspired thermal insulation enables high‐performance underwater actuation. Enhanced deformation, reduced heat dissipation, and rapid motion are validated through a bionic ray that exhibits straight and turning motions.
