The electricity market is evolving. For many years the electricity market was under rigid control. In the United States that rigid control was defined by the Public Utility Holding Company Act (PUHCA) of 1935, which prohibited nonutilities from participating in the market. The prohibition was accomplished by defining a utility as any entity that sold electricity for resale.

The giraffe is a ruminant mammal and the tallest animal in the world (average height for males is about 5 m or 16 ft). Giraffes include about 40 extinct species and the living okapi of the west African rainforest. In most species the neck was either short as in the okapi or long as in the extinct <i>Samotherium</i>. In no species was the neck as long as in the modern giraffe.
Industry:Science
Strips or cylinders of dividing cells located parallel to the long axis of the organ in which they occur. Radial enlargement of the cells derived from these meristems increases the diameter of the organ. The lateral meristem is concerned with secondary growth in the sense that its meristematic activity adds cells to the primary body which was derived from the apical meristems.
Industry:Science
Systems that attempt to reconstruct some or all of the audible dimensions of an acoustic event that occurred elsewhere. A sound-reproducing system includes the functions of capturing sounds with microphones, manipulating those sounds using elaborate electronic mixing consoles and signal processors, and then storing the sounds for reproduction at later times and different places.
Industry:Science
The complex of physical and chemical events of photosynthesis, respiration, and the synthesis and degradation of organic compounds. Photosynthesis produces the substrates for respiration and the starting organic compounds used as building blocks for subsequent biosyntheses of nucleic acids, amino acids and proteins, carbohydrates and organic acids, lipids, and natural products.
Industry:Science
The coal, sand, gravel, and other minerals extracted from the earth by mining continue to help fuel the world economy and improve the standard of living. However, the decades of mineral extraction and processing around the globe have produced a massive amount of waste containing toxic metals and materials that pollute land and water and pose health threats to humans and wildlife.
Industry:Science
The collection and observation of living organisms in the sea, including the quantitative determination of their abundance in time and space. The biological survey of the ocean largely depends on specially equipped vessels. Sampling in intertidal regions at low tide is one of the few instances where it is possible to observe and collect marine organisms without special apparatus.
Industry:Science
The common name for three living species of mammals in the family Elephantidae, one of several families included in the order Proboscidea. The remaining families contain extinct animals, such as the mammoth. Two of the living species (<i>Loxodonta africana</i> and <i>L. cyclotis</i>) are indigenous to Africa, and the other (<i>Elephas maximus</i>) ranges throughout Southeast Asia.
Industry:Science
The boundary between any two phases. Among the three phases, gas, liquid, and solid, five types of interfaces are possible: gas-liquid, gas-solid, liquid-liquid, liquid-solid, and solid-solid. The abrupt transition from one phase to another at these boundaries, even though subject to the kinetic effects of molecular motion, is statistically a surface only one or two molecules thick.
Industry:Science
The induction in plants of the competence or ripeness to flower by the influence of cold, that is, temperatures below the optimal temperature for growth. Vernalization thus concerns the first of the three phases of flower formation in plants. In the second stage, for which a certain photoperiod frequently is required, flowers are initiated. In the third stage flowers are unfolded.
