The formation of peak rings in large impact craters

Nov 18, 2016 · A different concept for peak-ring formation—the nested melt-cavity hypothesis—evolved from observations of peak-ring craters on the Moon and Mercury (5–7).This alternative hypothesis envisions that the uppermost central uplift is melted during impact, and an attenuated central uplift remains below the impact melt sheet and does not overshoot the …

Underpinning to Repair Faulty Foundations

Nov 05, 2018 · Underpinning is a method used to increase foundation depth or repairing faulty foundations. This might be the case if you plan to add stories to an existing structure or when the foundation has been damaged. One visible sign that your building needs underpinning is when cracks are visible. A building needs underpinning its foundation when ...

Radially Polarized Orbital Angular Momentum Beam Emitter

polarization in the silicon waveguide is used to excite quasi-TE WGM mode in the ring cavity. Fig. 1(a) is the schematic of a silicon microring cavity with the same dimension as [16]. The radius of the ring is 3.9 m, the width and height of waveguide are 500 nm and 220 nm, respectively. The

What if a hollow point bullet had a steel ring to prevent

Answer (1 of 8): Handgun cartridges lack the energy to cause the pressure inside the hollow cavity to reach such levels that it will cause the lead and copper to burst into fragments. This can be achieved with rifle cartridges however the bullet …

Does the area of the glenoid cavity of the scapula show

The area of the glenoid cavity was determined in 214 scapulae (114 male, 100 female). Mean values of 9.87 cm2 for the males and 7.18 cm2 for the females were found. Presentation of the values as a histogram showed a bimodal distribution indicating sexual dimorphism, which was confirmed by the Mann-Whitney-Wilcoxon test for unconnected samples.
