Carbon Capture and Storage (CCS) technology has attracted increasing attention as global climate change accelerates. dioxide removal processes under development include pressure swing adsorption (PSA) chemical absorption using amine solvents. In this paper, an ammonia solvent, which is relatively inexpensive good material properties, was used instead of amines in the carbon process simulation a...

OBJECTIVE The purpose of this clinical study was to compare the retention rates of two flowable restorative systems (Admira Flow and Grandio Flow) with that of a conventional resin-based sealant (Fissurit F). MATERIALS AND METHODS The study was planned as a clinical trial with a split-mouth design. A total of 122 sealants (38 Admira Flow, 41 Grandio Flow, 43 Fissurit F) were randomly applied ...

The recent development of flow electrochemical reactors has been remarkable, but efforts are still required to reduce the amount supporting electrolyte used in electrosynthesis. To address this problem, herein an advanced process combining and bipolar electrochemistry is proposed. developed system was successfully employed for anodic fluorination coupling organic compounds using low concentrati...

As tools for dynamic system modelling both conventional methods such as transfer function or state space representation and modern power flow based methods are available. The latter methods do not depend on energy domain, are able to preserve physical system structures, visualize power conversion or coupling or split, identify power losses or storage, run on conventional software and emphasize ...

We analyze a semidiscrete numerical scheme for approximating the evolution of parametric curves by elastic flow in Rn. The fourth order equation is split into two coupled second order problems, which are approximated by linear finite elements. We prove error bounds for the resulting scheme and present numerical test calculations that confirm our analysis.

Numerical simulation results for pure electroosmotic and combined electroosmotic/pressure driven Stokes flows are presented in the cross-flow and Y-split junctions. The numerical algorithm is based on a mixed structured/unstructured spectral element formulation, which results in high-order accurate resolution of thin electric double layers with discretization flexibility for complex engineering...

A hybrid genetic algorithm (HGA) approach is proposed for a lot-streaming flow shop scheduling problem, in which a job (lot) is split into a number of smaller sublots so that successive operations can be overlapped. The objective is the minimization of the mean weighted absolute deviation of job completion t imes from due dates.

The application of tracer techniques to the sugar industry is reviewed. This includes the investigation of residence time distribution in clarifiers, evaporators, continuous pans, crystallizers and fluidized bed dryers; the flow split in diffusers and evaporator vessels; leak detection; measurement of entrainment in vacuum pans and determination of system volumes such as cooling water ponds.

An Algorithm is presented which allows to split the calculation of the mean curvature flow of surfaces with or without boundary into a series of Poisson problems on a series of surfaces. This gives a new method to solve Plateau's problem for H-surfaces.
