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.
In conventional print media production, the production flow is divided into prepress (film and plate making), press (printed page/sheet production), and postpress/finishing (production of the final print media, such as a book or magazine). Today, digital print production systems may have integrated prepress, press, and postpress, such as a computer-to-press/direct-imaging printing system with on-press plate making.

Chemical thermodynamics is the study of the relationship between heat and other forms of energy involved in chemical and physical processes. It is concerned with properties of materials such as equilibrium, solubility, and phase changes, as these properties are important in understanding energy transformations. Gas solubility is a particularly interesting property as it relates to important aspects of life on Earth.

Digital proofing refers to processes that obtain hard-copy output directly from digital files for purposes of predicting the appearance or other aspects of printed matter. In practice, there are different purposes and, therefore, different requirements for digital proofs. The competing technologies in digital proofing include thermal transfer, electrophotographic, inkjet, dye sublimation, and photographic processes.

Extinct jawless vertebrates from the Ordovician, Silurian, and Devonian periods. Thelodonts had bodies covered by tiny scales, each a single toothlike unit (odontode). The scales varied in shape over the body. Each scale had a bony base pierced by a pulp cavity, with pulp canals extending into a dentinous crown. Thelodonts have been thought to be related to the Heterostraci or to the jawed vertebrates (Gnathostomata).

By botanical definition, fruits are seed-bearing organs of plants that function to protect and disseminate their contents. Most fruits can be classified as either fleshy or dry. The former are generally dispersed by organisms that consume the fruit and deposit the digestion-resistant seeds at another location. Seeds of dry or dehiscent fruit are typically dispersed by wind, gravity, or physical attachment to an animal.

Cyber defense is the practice of defending important computer-based information systems and networks from attack. Of primary concern is the protection of the information as it is stored and processed by computer systems and transmitted across networks. The three most important aspects of information that need to be protected, often referred to as the security triad, are its confidentiality, integrity, and availability.

For space flight, 2004 was a year of strong contrasts. Human and robotic space activities set new marks with a lineup of unique accomplishments, preparing the stage for new developments that will contribute greatly to human exploration beyond the Earth. At the same time, 2004 saw a decline in the utilization of space, as the number of launches to orbit plus the number of satellites reached the lowest levels since 1961.

Artificial analytical constructs for identifying plants. The identification, nomenclature, and classification of plants are the domain of plant taxonomy, and one basic responsibility of taxonomists is determining if the plant at hand is identical to a known plant. The dichotomous key provides a shortcut for identifying plants that eliminates searching through numerous descriptions to find one that fits the unknown plant.

Electromechanical components which, in combination with brushes, provide a continuous electrical connection between rotating and stationary conductors. Typical applications of slip rings are in electric rotating machinery, synchros, and gyroscopes. Slip rings are also employed in large assemblies where a number of circuits must be established between a rotating device, such as a radar antenna, and stationary equipment.

Frequency is the most accurately measured physical quantity. It is used to measure the time intervals from which time scales are generated. Accuracy is important in navigation, communications, space exploration, and scientific research, particularly in relativity. Recent developments in physics and communications have brought about advances in the accuracy of frequency measurement and in the accessibility of time scales.
