The authors have been designing a post-installed anchor that fixes itself into concrete material by expanding the tip in an upward direction, and conducted tensile loading tests to confirm its fundamental dynamic characteristics. test results on three types of specimens, with morphology as parameter, indicate final failure modes were all bar fractures, stable yield strength was confirmed. Addit...

We present here a novel, cost-effective method for increasing and controlling the ortho-para H2 (o-p H2) conversion yield. First, we invoke two processes derived from fundamental, surface science insights, based on the effect of molecular orientation on the hydrogen-solid surface reaction, i.e., dynamical quantum filtering and steering, and apply them to enhance the o-p H2 conversion yield.

The challenge of converting global agricultural food, fiber and energy crop cultivation into an ecologically and economically sustainable production process requires the most efficient agricultural management strategies. Development, control and maintenance of these strategies are highly dependent on temporally and spatially continuous information on crop status at the field scale. This paper i...
