We show that there exists an infinite family of pairwise non-isotopic Legendrian knots in the standard contact 3-sphere whose Stein traces are equivalent. This is first example such phenomenon. Different constructions developed article, including a annulus twist, explicit Weinstein handlebody equivalences, and discussion on dualizable patterns setting. These can be used to systematically constr...

For a packed bed in a distillation column, fmax is the maximum fractional liquid maldistribution that can be tolerated in a parallel column model whilst still being able to achieve the design separation. It was previously shown that fmax can be easily calculated from a conventional column simulation output and it is a measure of the sensitivity of a packed bed to maldistribution. In this paper,...

Abstract This chapter reviews research on solutes by fluvial geomorphologists in the period 1965–2000; growing links with biogeochemical are emphasized later chapter. Brief reference is necessarily made to some from before and after study period. In relation solutes, early sought relate short-term process observations long-term landform evolution. However, very quickly, moved into much more app...

Bed elevation, feature adjustments, and spawning use were monitored at three Chinook salmon (Oncorhynchus tschawytscha) spawning habitat rehabilitation sites to measure project longevity in a regulated river. Sites enhanced with 649–1323 m of gravel lost from 3–20% of remaining gravel volume annually during controlled flows of 8–70 m/s and 2.6–4.6% of placed material during a short-duration (19...

The Himalayan Rivers due to their steep bed and side slopes, narrow width and fragile geology of the region carry huge amount of sediment with them. Many runof-river hydro power projects are coming up on these rivers and suspended sediment enters into the power intake of these projects. Desilting chambers are provided to remove / minimize the suspended sediment from water conductor system. The ...
