GEOSYNTHETICS
بخشی از مقاله
Geosynthetic products of natural material
Although most of the geosynthetics are made from synthetic polymers, a few specialist geosynthetics, especially geotextiles, may also incorporate steel wire or natural biodegradable fibres such as jute, coir, paper, cotton, wool, silk, etc.
Biodegradable geotextiles are usually limited to erosion control applications where natural vegetation will replace the geotextile’s role as it degrades. Jute nets are marketed under various trade names, including geojute, soil saver, and anti-wash.
They are usually in the form of a woven net with a typical mesh open size of about 10 by 15 mm, a typical thickness of about 5 mm and an open area of about 65%.
Vegetation can easily grow through openings and use the fabric matrix as support. The jute, which is about 80% natural cellulose, should completely degrade in about two years. An additional advantage of these biodegradable products is that the decomposed jute improves the quality of the soil for vegetation growth.

Metro and Non-Metro Business Incubators: Similarities and Critical Differences
بخشی از مقاله
9.a Findings (selected)
Systematic differences by location
Only a small number of, mostly metro, incubators are private
No “official” standard for data collection [challenge for evaluation, which usually involves comparison] Self-evaluation by incubators is frequently deficient
Reliance on local/regional resources looks promising [e.g., Energy Xchange, Burnsville, NC] Universities, colleges and/or professional/ technical schools provide a home for and support many incubators, particularly in rural areas

FUNCTIONS OF RAILS
Rails provide hard, smooth and unchanging surface for passage of heavy moving loads with minimum friction between steel rail and steel wheel
Rails bear the stresses developed due to heavy vertical loads, lateral and braking forces and thermal stresses
The rail material used is such that it gives minimum wear to avoid replacement charges and failure due to wear
Rails transmit the loads to sleepers and consequently reduce pressure on ballast and formation below
