Diatoms inhabit fresh, brackish, or sea waters. Environmental changes ia the bodies of water where diatoms flourish are reflected by the different types of diatoms that may appear at different levels of the same deposit. 

The galvanic potential of metals can vary in response to environmental changes such as changes in fluid chemistry, fluid-flow rate, and fluid temperature. For example, at ambient temperatures steel is noble to zinc (as in galvanized steel). In waters of certain chemistries, however, a potential reversal may occur at temperatures above 140°F (60°C), and the zinc becomes noble to the steel. 

In the first stages of the development of an Action plan all control options are considered. In the case of lakes, this process is aided by a PC-based expert system , PACGAP, which looks at the physical and chemical characteristics of the lake to determine the most likely option for control. Once further, more detailed information has been collected on the lake s nutrient inputs and other controlling factors, amore complex interactive model can be used (Phytoplankton Response To Environmental CHange, PROTECH-2) to define the efficacy of proposed control options more accurately. This model is able to predict the development of phytoplankton species populations under different nutrient and stratification regimes. 

KSC results from an environmental change that affects the probability of failure of the affected components. An obvious example is an increased failure rate due to a change in conditions such as fire, stresses from an earthquake, or improper maintenance practices affecting several components. NUREG/CR-2300 classifies this type of common cause as "Type 1."... 

Has a world-wide database of federal and non-profit environmental research organizations that focus on the multiple aspects of global environmental change, including the regional effects on natural ecosystems, environments and resources as well as on human health, culture and social systems. 

Activator Protein-1 (API) comprises transcriptional complexes formed by dimers of members oftheFos, Jun, and ATF family of transcription factors. These proteins contain basic leucine zipper domains that mediate DNA binding and dimerization. They regulate many aspects of cell physiology in response to environmental changes. 

An argument can be made that chemistry is a critically important science for understanding the causes and effects of much of the environmental change observed today. Consider the logical progression of ideas already discussed, i.e. 

Although natural selection is the only evolutionary agent that adapts organisms to their environments, the course of evolution has been profoundly influenced by major environmental changes, some of which had catastrophic effects. Some of these events resulted from Earth s internal processes, such as the activity of volcanoes and the shifting and colliding of continents. Others were the result of external events, such as collision of meteorites with Earth.

Records of past environmental change are preserved in a broad range of Earth materials. Past environments are inferred from "proxy" records, meaning measurements of physical and chemical parameters of marine and terrestrial sediment, polar ice, and other materials that were in some way influenced by their environment during accumulation. Examples of proxy records are the distribution of glacial deposits, the isotopic composition of terrestrial and marine sediments and ice, the abundance and species composition of plant and animal fossils, and the width of tree rings. 

This chapter is a brief introduction to Earth s historical environmental changes, with emphasis on the recent ice-age cycles. We chose this emphasis because preservation of these environmental records is much better than for earlier times, and because the ice ages constitute drastic changes in global environment which have...
