Outline of Geophysics
The following outline is provided as an overview of and topical guide to geophysics: Geophysics – the physics of the Earth and its environment in space; also the study of the Earth using quantitative physical methods. The term geophysics sometimes refers only to the geological applications: Earth's shape; its gravitational and magnetic fields; its internal structure and composition; its dynamics and their surface expression in plate tectonics, the generation of magmas, volcanism and rock formation. However, modern geophysics organizations have a broader definition that includes the hydrological cycle including snow and ice; fluid dynamics of the oceans and the atmosphere; electricity and magnetism in the ionosphere and magnetosphere and solar-terrestrial relations; and analogous problems associated with the Moon and other planets.

Over Illumination
Over illumination is the presence of lighting intensity higher than that which is appropriate for a specific activity. Over illumination was commonly ignored between 1950 and 1995, especially in office and retail environments. Since then, however, the interior design community has begun to reconsider this practice. Over illumination encompasses two separate concerns: (1) Unnecessary electric lighting is expensive and energy-intensive. Lighting accounts for approximately 9% of residential electricity use (As of 2001) and about 40% of commercial electricity use. (2) Excessive levels of artificial light may adversely affect health. These detrimental effects may depend on the spectrum as well as the overall brightness level of light. Over illumination can be reduced by installing occupancy sensors, using natural sunlight whenever possible, turning off lights when leaving a room, or changing the type of lightbulb. Over illumination does not refer to snowblindness, where high exposure to ultraviolet light causes physical damage to the eye. Too little light, the opposite of over illumination, is associated with seasonal affective disorder.

Overview of Extracellular Polymeric Substances
Extracellular polymeric substances (EPS) are complex extracellular polymers with high molecular weight, which are metabolic products of microorganisms and result from effluent organic matter and microbial lysis or hydrolysis. EPS were proved to have the ability to absorb and biodegrade certain substances. The main components in EPS were found to influence the properties of microbial floccules, such as transfer, surface hydrophilicity/hydrophobicity, and aggregate stability.

Overview of Water Electrochemistry
Seawater is the most abundant supply of water and the ideal and cheapest electrolyte. Because it is a green and renewable chemical process, water electrolysis has earned a lot of interest among the different hydrogen production techniques. Basis of water electrolysis include general theoretical concepts: chemical, physical, and electrochemical concepts. Research has focused on the specific seawater electrolysis parameters: cathodic evolution of hydrogen; concurrent anodic evolution of oxygen and chlorine; specific seawater catalyst electrodes, and seawater electrolyzer efficiency. A sustainable technology development must also capitalize on known and emerging technologies; protecting the environment; utilization of green, renewable energies as sources of electricity; and above all, economic efficiency as a whole.

Oxide Minerals
The oxide mineral class includes those minerals in which the oxide anion (O2−) is bonded to one or more metal alloys. The hydroxide-bearing minerals are typically included in the oxide class. The minerals with complex anion groups such as the silicates, sulfates, carbonates and phosphates are classed separately. Simple oxides: Hydroxide subgroup:

Paedotherium
Paedotherium is an extinct, potentially paraphyletic genus of Notoungulate, belonging to the family Hegetotheriidae, composed of small-sized, rodent or lagomorph-like South American ungulates. Four species are unambiguously recognized, from the Late Miocene to the Pleistocene of Argentina , and from the late Miocene of Bolivia and Chile .

Page LaPyout (Cartography)
Page layout, also called map layout or map composition, is the part of Cartographic design that involves assembling various map elements on a page. This may include the map image itself, along with titles, legends, scale indicators, inset maps, and other elements. It follows principles similar to page layout in graphic design, such as balance, gestalt, and visual hierarchy. The term map composition is also used for the assembling of features and symbols within the map image itself, which can cause some confusion; these two processes share a few common design principles but are distinct procedures in practice. Similar principles of layout design apply to maps produced in a variety of media, from large format wall maps to illustrations in books to interactive web maps, although each medium has unique constraints and opportunities.
