Experimental Study on Bonding Performance between Prestressed Concrete Pipe Piles and Core Grout

open access: yesAdvances in Civil Engineering, 2023
To make the bearing capacity tests safer and more affordable for prestressed high-strength concrete (PHC) piles, this paper proposes a reaction device for anchor piles filled with core grout based on the geometric and mechanical characteristics of PHC ...

Insulation for cryogenic tanks has reduced thickness and weight [PDF]

open access: yes, 1966
Dual seal insulation, consisting of an inner layer of sealed-cell Mylar honeycomb core and an outer helium purge channel of fiber glass reinforced phenolic honeycomb core, is used as a thin, lightweight insulation for external surfaces of cryogenic ...

Effects of inner electrons on atomic strong-field ionization dynamics

open access: yes, 2014
The influence of inner electrons on the ionization dynamics in strong laser fields is investigated in a wavelength regime where the inner electron dynamics is usually assumed to be negligible. The role of inner electrons is of particular interest for the

VLBA Imaging of NGC 4261: Symmetric Parsec-scale Jets and the Inner Accretion Region [PDF]

open access: yes, 1997
We observed the nuclear region of NGC 4261 (3C270) with the VLBA at two frequencies (1.6 and 8.4 GHz) simultaneously. We find that the position angle of the parsec-scale radio axis agrees, within the errors, with the position angle of the VLA-scale jet ...

Retrograde waves in tropical cyclone inner-core

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2016
This study presents an extension of Kelvin's vortex wave model for the inner-core region of tropical cyclone-like vortices. By considering a more suitable approximation for tropical cyclones (TCs) for which the horizontal scale of the TC inner-core is ...

Thermocapillary flow‐induced core release from double‐emulsion droplets in microchannels

open access: yesDroplet, 2023
The use of double emulsions (DEs), which represent colloidal structures composed of droplets nested within droplets, can provide for unparallel droplet manipulation in droplet‐based microfluidic technology due to their unique core–shell structures.

Polarization Characteristics of Double-Clad Elliptical Fibers [PDF]

open access: yes, 1990
A scalar variational analysis based on a Gaussian approximation of the fundamental mode of a double-clad elliptical fiber with a depressed inner cladding is studied.

Mechanical thermal motor [PDF]

open access: yes, 1976
An apparatus is described for converting thermal energy such as solar energy into mechanical motion for driving fluid pumps and similar equipment. The thermal motor comprises an inner concentric cylinder carried by a stationary core member.

Candy Wrapper for the Earth's Inner Core [PDF]

open access: yesScientific Reports, 2013
AbstractRecent global expansion of seismic data motivated a number of seismological studies of the Earth's inner core that proposed the existence of increasingly complex structure and anisotropy. In the meantime, new hypotheses of dynamic mechanisms have been put forward to interpret seismological results.
