Decoupage or découpage ( / ˌdeɪkuːˈpɑːʒ /; [ 1] French: [dekupaʒ]) is the art of decorating an object by gluing colored paper cutouts onto it in combination with special paint effects, gold leaf, and other decorative elements. Commonly, an object like a small box or an item of furniture is covered by cutouts from magazines or from ...
A hot, less-dense lower boundary layer sends plumes of hot material upwards, and cold material from the top moves downwards. Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy ( heat) between physical systems. Heat transfer is classified into various mechanisms ...
Technology assessment – Research area dealing with trends in science and technology and related social developments; Technology life cycle – Development, ascent, maturity, and decline of new technologies; Technology transfer – Process of disseminating technology
Earth's tectonic evolution over time from a molten state at 4.5 Ga, [11] to a single-plate lithosphere, [24] to modern plate tectonics sometime between 3.2 Ga [25] and 1.0 Ga [26] Primordial heat energy comes from the potential energy released by collapsing a large amount of matter into a gravity well , and the kinetic energy of accreted matter.
Horizontal gene transfer ( HGT) or lateral gene transfer ( LGT) [ 1][ 2][ 3] is the movement of genetic material between organisms other than by the ("vertical") transmission of DNA from parent to offspring ( reproduction ). [ 4] HGT is an important factor in the evolution of many organisms. [ 5][ 6] HGT is influencing scientific understanding ...
Thermochemistry. Thermochemistry is the study of the heat energy which is associated with chemical reactions and/or phase changes such as melting and boiling. A reaction may release or absorb energy, and a phase change may do the same. Thermochemistry focuses on the energy exchange between a system and its surroundings in the form of heat.

Paper marbling is a method of aqueous surface design, which can produce patterns similar to smooth marble or other kinds of stone. [ 1] The patterns are the result of color floated on either plain water or a viscous solution known as size, and then carefully transferred to an absorbent surface, such as paper or fabric.
