McGraw Hill Financial, Inc. is an American publicly traded corporation headquartered in Rockefeller Center in New York City. Its primary areas of business are financial, publishing, and business services.
The emission of light by living organisms that is visible to other organisms. The enzymes and other proteins associated with bioluminescence have been developed and exploited as markers or reporters of other biochemical processes in biomedical research. Bioluminescence provides a unique tool for investigating and understanding numerous basic physiological processes, both cellular and organismic.
Industry:Science
The large-scale, systematic, and irreversible changes with time of the structure and composition of a star.
Industry:Science
The genes encoding the genetic information to make antibodies (immunoglobulins) of different specificities and classes. Specificity is encoded in the variable region of the antibody, which is generated by assembling gene segments through a process called rearrangement. Biological activity of an antibody is established through a process called class switching in the constant part of the antibody.
Industry:Science
The application of the photographic process to astronomy, including monochrome photography and color photography.
Industry:Science
The Crab Nebula is the remnant of a tremendous stellar explosion witnessed by Chinese astronomers in 1054. The explosion, called a supernova, occurred at a distance of about 2000 parsecs from the Earth (1 parsec = 1.9 × 10<sup>13</sup> mi = 3.1 × 10<sup>13</sup> km = 3.26 light-years). Even so, it was bright enough to be visible in the daytime sky for 3 weeks and in the nighttime sky for 2 years.
Industry:Science
That branch of mathematics which deals with matrices whose elements are functions of one or more independent variables.
Industry:Science
The elementary building blocks in a mathematical tool for analyzing functions. The functions to be analyzed can be very diverse; examples are solutions of a differential equation, and one- and two-dimensional signals. The tool itself, the wavelet transform, is the result of a synthesis of ideas from many different fields, ranging from pure mathematics to quantum physics and electrical engineering.
Industry:Science
The branch of physics concerned with the motion of charged particles under the influence of electric and magnetic fields.
Industry:Science
The engineering aspects of flight and navigation in space. The latter is also known as astronautics. The terminology thus parallels aeronautical engineering and aeronautics as applied to aviation. Astronautical engineering deals with vehicles, instruments, and other equipment used in space, but not with the sociological or economic aspects of space flight, except as they influence the equipment.
Industry:Science
The complex of cartilages and related structures at the opening of the trachea, or windpipe, into the pharynx, or throat.
