Estimation of Wax Deposition in Subsea Pipelines
… multi-physics low dimensional model forecasting wax deposition rate within subsea production pipelines. This research employs experiments from 1-D and 2-D multiphase flow that have been successfully matched by a combined physics model on a closed-loop structure where the measuring length was 2.5m …

The Development of a Knowledge-Based Wax Deposition, Three Yield Stresses Model and Failure Mechanisms for Re-starting Petroleum Field Pipelines. Building on Chang and Boger’s Yield Stresses Model, Bidmus and Mehrotra’s Wax Deposition and Lee et al.’s Adhesive-Cohesive Failure Concepts to better Underpin Restart Operation of Waxy Crude Oil Pipelines
… and elastic limits) to describe yielding of waxy crude oils cooled below the wax appearance temperature (WAT). At the time, the limits in rheological instruments were such that they never actually measured the elastic-limit, a key fundamental property. Using modern instruments, this research …

Characterization of xtcl mutant with reduced cuticular wax accumulation
Cuticular wax is a component of the plant cuticle, the lipid barrier which covers the surface of above ground primary plant organs and plays important protective roles. The isolation of wax deficient mutants from Arabidopsis and other plants resulted in identification and isolation of genes …

Investigations on the influence of CO2 on leaf epidermal development in Arabidopsis thaliana
… cytological features and epicuticular wax deposition respond dynamically to environmental factors including CO2 concentrations (p[CO2]). Gas exchange is controlled by stomata, epidermal pores flanked by a pair of guard cells that regulate their aperture in response to light, humidity …

An Experimental Study on the Effects of Heat and Chemical Inhibitors on the Flow Behaviour of Waxy Crude Oils. The Effects of Heat and Chemical Inhibitors on the Rheological Properties of Waxy Crude Oils with regard to Pumping in Pipelines
Waxy crude oils (1/3 of oil produced worldwide), pumping through pipelines considered risky operation due to the crude wax content (15-40 wt.%) and to the temperature at which wax supersaturates and precipitates, leading to the danger of pipe blockage, eventually resulting, in multimillion dollars …
