Performance of large-bore tapered-roller bearings under combined radial and thrust load at shaft speeds to 15,000 rpm [PDF]
The performance of 120.65-mm bore tapered roller bearings was investigated at shaft speeds up to 15,000 rpm. Temperature distribution and bearing heat generation were determined as a function of shaft speed, radial and thrust loads, lubricant flow rate ...

Jet Pump Technology for Enhanced Oil Production
Aldrende oljefelt opplever ofte fallende produksjon i enkelte brønner som følge av lavere trykk, økende vannmengder og endrede reservoaregenskaper. Ula-platformen har vært i drift siden 1986 og har flere slike brønner. Metoden som brukes på Ula i dag for å hjelpe på produksjonen er gassløft-teknologien.

Sentience in cephalopod molluscs: an updated assessment
ABSTRACT This article evaluates the evidence for sentience – the capacity to have feelings – in cephalopod molluscs: octopus, cuttlefish, squid, and nautilus. Our framework includes eight criteria, covering both whether the animal's nervous system could support sentience and whether their behaviour indicates sentience.
