The cognitive theory of conceptual blending models human creativity as a mental process that combines two mental spaces into a new mental space, called a blend. According to this theory, a blend is constructed by taking the commonalities among the input mental spaces into account, to form a so-called generic space, and by projecting their non-common structure in a selective way to the novel ble...

Dr Inventor is a tool that aims to enhance the professional (Pro-c) creativity of researchers by suggesting novel hypotheses, arising from analogies between publications. Dr Inventor processes original research documents using a combination of lexical analysis and cognitive computation to identify novel comparisons that suggest new research hypotheses, with the objective of supporting a novel r...

In this paper, the connection between metaphor, metonymy, blending and humour is discussed against an analysis of puns in print advertisements featuring both visual and verbal elements. The analysis is based on the theory of conceptual blending (Fauconnier and Turner 1994, 1996 etc.) and on analyses of humour within that framework made by Coulson (1996, 2001, in press), but it also draws on obs...

The removal of chemically damaged DNA bases such as 3-methyladenine (3-MeA) is an essential process in all living organisms and is catalyzed by the enzyme 3-MeA DNA glycosylase I. A key question is how the enzyme selectively recognizes the alkylated 3-MeA over the much more abundant adenine. The crystal structures of native and Y16F-mutant 3-MeA DNA glycosylase I from Staphylococcus aureus in c...

The removal of acid gases from gas streams by using suitable solvent like alkanolamine, commonly referred to as gas sweetening, is a technology that has been in use industrially for over half a century. In this work artificial neural network (ANN) has been used to predict the equilibrium solubility of CO2 over the alkanolamine solvents N-methyldiethanolamine (MDEA) and 2-amino-2-methyl-1-propan...

As energy systems require flexible and responsive power generators to combat network imbalances, CO 2 post-combustion capture (PCC) technologies need be capable of transient operation. However, currently only amine absorption has been investigated for its efficacy in Flexible-PCC. Within this study we develop validate a vacuum-pressure swing adsorption (VPSA) process model, processing 33.8 kg/s...

The present study investigates the hydrodynamics and mass transfer of liquid–gas ejector using three-dimensional (air–water) two-dimensional (CO2/air-MEA (Monoethanolamine) solution) computational fluid dynamics (CFD) modeling. For 3D simulation, validation CFD results this with experimental data (error less than 5%) showed high simulation accuracy. effects motive liquid flow rate outlet pressu...

In flowering plants, two cells are fertilized in the haploid female gametophyte. Egg and sperm nuclei fuse to form the embryo. A second sperm nucleus fuses with the central cell nucleus that replicates to generate the endosperm, which is a tissue that supports embryo development. MEDEA (MEA) encodes an Arabidopsis SET domain Polycomb protein. Inheritance of a maternal loss-of-function mea allel...
