FUTURE EXTENSION ON GEOSYNTHETICS LINERS

Geosynthetics in geoenvironmental engineering

Geosynthetics are planar polymeric products, which are used in connection with soil, rock or other soil-like materials to fulfill various functions in geoenvironmental engineering. Geosynthetics are of ever-growing importance in the construction industry. Sealing of waste storage facilities to safely prevent the emission of wastewater, landfill gas and contaminated dust as well as the diffusion...

Soil Reinforcement and Geosynthetics

In the context of sustainable development which is a balancing act between the fulfilment of human needs and the protection of the natural environment, the use of natural fibers such as coir in geotechnical applications is desirable. Reinforcing the soil with coir fibers/coir geotextiles is a cost effective solution to the ground/soil improvement problems. The effects of fiber parameters on the...

Milestones and the Future for Cooperative Extension

Milestones like the centennial of the Cooperative Extension system are significant in any organization. Milestones measure progress along a path, but can also give reassurances that travelers are on the right track. As Extension moves into the next century, we must continuously ask ourselves if it is focused and on the right path. What are some guiding principles that we need to follow? What ar...

Variability in LINERs

A small number of LINERs have been seen to display variable Hα emission with a very broad, double-peaked profile. Recent observations with the Hubble Space Telescope indicate that such emission may be a common attribute of LINERs. The double-peaked or doubleshouldered line profiles resemble those found in a subset of broad-line radio galaxies. Several lines of argument suggest that such feature...
