ShellsSteel trussesIn this study, we present the earthquake resistance of three types of reinforced concrete shells, having three different plans and contours. In the Memorial Museum near the city of Karachaevsk, Israel, a reinforced concrete monolithic shell serves as the building's roof and ...
@donasmrs-- You can find Italian pastry shops in many metropolitan areas in the US. There is one close to where I live in Virginia and they have amazing pastries, cakes, cookies and chocolates. I'm a huge fan of their cookies and angel wings. I buy them for myself and I also buy...
Porto Ferro beach is located to thenorthern side of the Italy’s Island, Sardinia. It stretches around 2 km and dominated by three striking look-out towers that date back to XVII century. The orange color of the beach is formed due to the mixture of orange limestones, crushed shells and ...
The ESI parameters in positive ionization mode were adjusted as follows: source temperature 150 °C; cone voltage 30 eV; capillary voltage 3 kV; desolvation temperature 440 °C; cone gas flow 50 L/h; and desolvation gas flow 900 L/h. The MS2 settings were kept at 30 eV of collision ...
The purpose of this study was to investigate the effect of Tremella fuciformis polysaccharides on the physicochemical properties of freeze–thawed cone chestnut starch. Various aspects, including water content, crystallinity, particle size, gelatinization, retrogradation, thermal properties, rheological properti...
This compound can also be obtained from marine bio-waste, including crustacean shells, supporting the blue bioeconomy growth [23,24,25]. Several investigations have suggested that astaxanthin is able to counteract distinct pathophysiological mechanisms in patients with neurodegenerative diseases, revealing ...
where ramin, rbmin, and r1min are minimum values of radii ra, rb, and r1; l is the distance from the beginning of the screw thread with the small cone base to a certain turn of it. 2.3. Analytical Method of Screw Thread Model Using Tool Back-Rake Parameter In Figure 5, the generat...
[21]’s research on truncated conical portholes suggested the use of an optimal cone angle for minimizing stress, and Di et al. [22] examined the effects of defects and aspect ratios on the load capacity of spherical PMMA shells. Wang et al. [23] performed quasistatic loading-unloading ...
During carbonization, volatile compounds were removed from the Ricinus communis shells, giving rise to a honeycomb structure with different pore sizes and shapes (Figure 4a,b). There is an uneven distribution of microblocks and cavities in the samples regardless of the KOH activation. As a result...
In the presence of deep-sea hydrostatic pressure, the sealing performance of the conical contact surface exhibits greater stability and reliability when compared to a planar surface. The contact area between the window and the cone of the window seat is large, and the extrusion deformation of the...
