OA factors extracted from factor analysis of highly time-resolved aerosol mass spectra correspond to lumped groups of molecules that are linked to each other by similar sources or processes.
To overcome such difficulties, our approach permits the lumping of several molecules into a signaling specie in the model network.
The signature metaphor for this species of emergence is water: the individual molecules of H2O don't exhibit properties like coolness or liquidity or the ability to slake thirst -- those all emerge at a macro-scale when masses of molecules are lumped together.
The rates of degradation are lumped together in a single rate (r d ) which is proportional to the total amount of molecules C T v, i.e. r d = k d C T v.
Air is made of molecules.
No other kinds of molecules worked.
They called this chain of molecules PROTACs.
Familiar objects such as shoes and ships and lumps of sealing wax, and their parts as revealed by empirical scientific investigation, such as crystals, molecules and atoms, are concrete particulars or things.
Great lumps of squirrels crashing around.
Each molecule of rotaxane-which was invented by chemist Fraser Stoddart at the University of California, Los Angeles-consists of a long axle with two lumps of atoms at each end, and a ring of atoms circling the axle.
