Bioregenerative life support systems (BLSS) are artificial ecosystems consisting of many complex symbiotic relationships among higher plants, animals, and microorganisms. As the most advanced life support technology, BLSS can provide a habitation environment similar to Earth's biosphere for space missions with extended durations, in deep space ...
Real-life landslide on a slope. Slope stability refers to the condition of inclined soil or rock slopes to withstand or undergo movement; the opposite condition is called slope instability or slope failure. The stability condition of slopes is a subject of study and research in soil mechanics, geotechnical engineering, and engineering geology.
Vegetation and slope stability are interrelated by the ability of the plant life growing on slopes to both promote and hinder the stability of the slope. The relationship is a complex combination of the type of soil , the rainfall regime , the plant species present, the slope aspect , and the steepness of the slope.
The Encyclopedia of Life Support Systems (EOLSS) is an integrated compendium of twenty one encyclopedias.. One of the largest database repositories on the web, dedicated to the health, maintenance and future of the web of life on planet Earth, focusing on the complex connections among all the myriad aspects from natural and social sciences through water, energy, land, food, agriculture ...
The operation of re-profiling a slope with the aim of improving its stability, can be achieved by either: Lowering the angle of the slope, or; Positioning infill at the foot of the slope; Slope angles can be reduced by digging out the brow of the slope, usually in a step-wise fashion.
The life support system of a surface saturation accommodation facility provides breathing gas and other services to support life for the personnel under pressure. It includes the following components: [12] Underwater habitats differ in that the ambient external pressure is the same as internal pressure, so some engineering problems are simplified.
Slope stability analysis is a static or dynamic, analytical or empirical method to evaluate the stability of slopes of soil- and rock-fill dams, embankments, excavated slopes, and natural slopes in soil and rock.
The slope, planform, confinement, and cross-sectional shape and dimensions of a stream, and the grain-size distribution of bed sediment affect aquatic habitat. Under less disturbed situations, a narrow, steep-walled cross section provides less physical area for habitat than does a wide cross section.
