Maxometers (peak wind speed anemometers) [PDF]

open access: yes, 1973
An instrument for measuring peak wind speeds under severe environmental conditions is described, comprising an elongated cylinder housed in an outer casing.

An analysis of contractile and protrusive cell behaviors at the superficial surface of the zebrafish neural plate

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The forces underlying convergence and internalization of the teleost neural plate remain unknown. To help understand this morphogenesis, we analyzed collective and individual cell behaviors at the superficial surface of the neural plate as internalization begins to form the neural keel in the hindbrain region of the zebrafish embryo.

The mechanism of anaphase spindle elongation: uncoupling of tubulin incorporation and microtubule sliding during in vitro spindle reactivation. [PDF]

open access: yes, 1988
To study tubulin polymerization and microtubule sliding during spindle elongation in vitro, we developed a method of uncoupling the two processes. When isolated diatom spindles were incubated with biotinylated tubulin (biot-tb) without ATP, biot-tb was ...

Pre‐oviposition development of the brown anole (Anolis sagrei)

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The brown anole, Anolis sagrei, has emerged as a representative squamate species for developmental studies during the past decades. Novel functional tools have been established to manipulate embryogenesis through genome editing or the introduction of small molecule inhibitors, and their effective use requires a thorough ...

In vitro reactivation of spindle elongation in fission yeast nuc2 mutant cells. [PDF]

open access: yes, 1990
To investigate the mechanisms of spindle elongation and chromosome separation in the fission yeast Schizosaccharomyces pombe, we have developed an in vitro assay using a temperature-sensitive mutant strain, nuc2.

Study on Compound Percussive Drilling: Rock‐Breaking Mechanism of High Confining Pressure Formation in the East China Sea

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT The effect of improving the depth of penetration (ROP) in deep, high‐confining pressure formation is closely related to the rock‐breaking method, which has become a bottleneck restricting the efficient development of oil and gas. Based on the current engineering practice of the Xihu block in the East China Sea Basin, experimental research on ...
