Growth model of cavity generated by the projectile impacting liquid-filled tank
Defence Technology, 2020 The high-speed impact of a projectile on a liquid-filled tank causes the hydraulic ram, in which a cavity is formed. To study the growth characteristics of the cavity, the formation mechanism of the cavity is analyzed.

Optimisation of Inner Diameter to Outer Diameter Ratio of Axial Flux Permanent Magnet Generator
IOSR Journal of Electrical and Electronics Engineering, 2014 This paper presents design of axial flux permanent magnet generator using torus construction of stator with plastic material. To maximise the efficiency of the generator, the losses are to be minimized in proposed N-S Arrangement iron loss is absent and only copper losses are present. To minimise the copper loss for a given rating, the per phase stator

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
