Olivier Kessler-Gay will take over the role on March 3. Lauren McLemore SurveysJan 29, 2025 Consumer Confidence Slips for Second Consecutive Month It hit a four-month low in January due to concerns about the job market, though consumers remain bullish about the stock market. ...
Diamond rings can come with as many as six or eight prongs in the setting. However, the number of prongs does not indicate your diamond will stay in place securely. In other words, the stone can fall out because of how the prongs are designed. Likewise, more prongs do nothing to improve...
aDiamond-back moths overwinter as adults if the temperatures do not fall too low. As most moths die during the winter in the more northern parts of their distribution, infestations start in the following year only when immigrating moths from warmer areas reinfest the area. The moths are ...
Overall, considering the insignificant effect of these regions as well as expected major effect of coatings in the highly loaded region, the explicit model is used for this investigation. Figure 8. Velocity of the tappet during engine cycle. Figure 9. Contact force between the cam and the ...
The novel design of a terahertz large aperture photoconductive antenna (LAPCA) is reported. It features a longitudinal orientation of the bias electric field within the photoconductive substrate, and has the advantage of a small interelectrode gap, resul
In the LEO, hyperthermal atomic oxygen is the dominant species and the main cause of deterioration in the properties of astronautical materials [1,2,3,4]. Solid lubricant used in artificial satellites must therefore have sufficient resistance against irradiation by atomic oxygen. Diamond-like carbon...
The changes that appeared in the crystal structure of a natural diamond under the influence of a pulsed femtosecond laser (525 nm) were comprehensively investigated using Fourier-transform infrared (FT-IR), electron paramagnetic resonance (EPR), and photoluminescence (PL) spectroscopy methods. It is...
