Abstract Coating of Mg alloys with Mg-phosphate is usually performed by complex and costly methods. This work was mainly aimed at using ceramic for metal implants simple cost-effective spin coating combined a sol–gel approach. Where, particles were dispersed different percentages (0, 10, 30 wt. %) in the glass sol (85 SiO 2 – 10 CaO 5 P O system) as solution. The coated substrates characterized...

Pitaya (Hylocereus undatus) is a non-climacteric fruit that reaches its best eating quality when harvested ripe, decreasing thereafter during storage (CHIEN et al., 2007). As a new crop, there have been limited studies focused on extending the postharvest quality of pitaya fruit. The main postharvest problems of pitaya fruit are mechanical injury, chilling injury, decay, and water loss (NERD et...

The optimization design of the section morphology of large-span tunnels plays an important role for saving cost and improving the engineering stability. The flat ratio of tunnel which is as an important control index, its rationality is the key problem in the design of tunnels. Program with Python to set up the dynamic calculation model of a large-span tunnel planned to be constructed which can...

The aerial transport of tiny arthropods including wing-less species has been well documented. The initiation of aerial dispersal in most instances is not a passive phenomenon, but involves identifiable behaviors in response to specific stimuli. Here we describe a construction of wind tunnel suitable for close-up observation of micro-arthropods behavior under various conditions. The tunnel was m...

Soils contaminated with low levels of heavy metals and other trace elements are now frequently used for vegetable growing. In this situation, heavy metals and trace elements from these polluted soils may accumulate in the agricultural plants being grown in them and thereby enter the human food chain. The objectives of this study are to elucidate the effects of growth conditions, manipulated by ...

in this work, laser bending of perforated sheets has been investigated numerically. laser bending of perforated sheets is more complicated than non-perforated sheets due to their complex geometries. in this paper, laser bending of perforated sheets is studied numerically in the form of thermo-mechanical analysis with abaqus/implicit code. for this purpose, the effects of process and sheet param...
