Biological flow receptors show astonishing performance and are used as models for the design of novel flow ***,the functional importance of interfacial microstructures is seldom discussed in previous review ***,this review summarises the underlying biomechanical principles in the biological flow receptors and describes the recent progress in bio-inspired flow sensors,in which the underlying sensing-enhancement mechanisms are emphasised.

To infuse water into oil reservoir by a high-pressure pump to let oil residuum issue out of oil wells is a problem of two-phase immiscible flow displacement. J. Douglas and D. W. Peaceman proposed a finite-difference numerical solution of this problem in 1959. Though the numerical simulation has begun, the complete theoretical analysis is seldom reported. In this paper we propose the

In 1970, during the excavations in the area of the Great Temple of Boghazkǒy (the Lower City) a cuneiform tablet was found that at once attracted the attention of Hittitologists. This tablet (Bo 70/10, KBo XXII 2) is the Old Hittite original, written in the old ductus, of KBo III 38 (=2 BoTU 13). The latter, known from the autograph of M.H. Figulla (1918), is a New Hittite copy with a very characteristic ductus and a preference for Akkadian forms where the Old Hittite version uses Hittite words or, more seldom, Sumerograms. The text, known as The Legend about the Queen of Kanis and the City of Zalpa, was published in transliteration and with a commentary by H. Otten (1973).
