Life cycle assessment (LCA) is sometimes referred to synonymously as life cycle analysis in the scholarly and agency report literatures. [7] [1] [8] Also, due to the general nature of an LCA study of examining the life cycle impacts from raw material extraction (cradle) through disposal (grave), it is sometimes referred to as "cradle-to-grave analysis".
Life-cycle assessment (LCA or life cycle analysis) is a technique used to assess potential environmental impacts of a product at different stages of its life. This technique takes a "cradle-to-grave" or a "cradle-to-cradle" approach and looks at environmental impacts that occur throughout the lifetime of a product from raw material extraction, manufacturing and processing, distribution, use ...
The International Space Station is a platform for scientific research that requires one or more of the unusual conditions present in low Earth orbit (for example microgravity, -radiation and extreme temperatures). The primary fields of research include human research, space medicine, life sciences, physical sciences, astronomy and meteorology.

Industrial products – Product environmental life cycle analysis (LCA) is used for identifying and measuring the impact of industrial products on the environment. These EIAs consider activities related to extraction of raw materials, ancillary materials, equipment; production, use, disposal and ancillary equipment.
Perceptual learning is a more in-depth relationship between experience and perception. Different perceptions of the same sensory input may arise in individuals with different experiences or training. This leads to important issues about the ontology of sensory experience, the relationship between cognition and perception. An example of this is ...
The most prominent common aspects of personally experiencing the Earth from space are appreciation and perception of beauty, unexpected and even overwhelming emotion, and an increased sense of connection to other people and the Earth as a whole. [3]
The life of such a system is limited, as the entropy of a closed system can only increase with time. But if the otherwise closed system is allowed to accept high-temperature radiant energy from an external source (e.g., sunlight) and to reject low-temperature waste heat to deep space, it can continue indefinitely.
