Two hinged steel joints were installed, one at each end of the specimens. The axial compression load was applied load-controlled via a concrete cross-beam by two hydraulic jacks of 75 kN capacity each. In order to protect the load-bearing setup and also prevent failure at joint positions, stone wool blocks were used to insulate the joints for a distance of up to 300 mm from the specimen ends (see Figure 6.26). The mechanical loading process was the same for all the specimens.

HL-60-M cells challenged by glass wool code A or stone wool code G fibres preincubated in unbuffered sahne for about 4 weeks, produced less intense luminol-enhanced chemiluminescence, as compared with freshly suspended fibres (Zoller and Zeller 2000). MMVF 21 and HT-N fibres as well as crocidohte and erionite did not show any decrease in chemiluminescence intensity after incubation in aqueous solutions.

The use of thermal insulation dates back to ancient times, when primitive man used animal skins for clothing and built structures for protection from the elements. Primitive insulation included fibrous materials such as animal fur or wool, feathers, straw, or woven goods. Bricks and stone, while not highl y efficient thermal insulation, provided protection from the elements, reduced the loss of heat from fires, and provided large masses that moderate temperature changes and store heat. 

Cross-linking the fibers with radiation lead to durable-stretch fabrics. The fabrics can be made by any process, such as weaving and knitting, and from any combination of cross-linked, heat-resistant olefin elastic and inelastic (hard) fibers, e.g., cotton and wool. These fabrics exhibit excellent chemical resistance (e.g., chlorine or caustic resistance) and durability, that is, they retain their shape and feel (hand) over repeated exposure to processing conditions, such as stone-washing, dye-stripping, and PET-dyeing. 

In the case of soil analysis, a 2.0cm i.d.x30cm column is used. Stones, roots and other gross impurities were removed, and the soil was reduced to a size between 30 and 60 mesh. 20g of soil was packed into the column between two glass wool plugs. Insecticides were desorbed from the soil by passing small volumes of acetone toluene (1 1) through the column at a rate...

Materials define the face of society. Initially, since prehistoric times - and to this day - materials were selected amongst those available in nature. These included, besides stones and metals, basic ingredients obtained from plants, crops, and animals in the form of, for example, wood, flax, wool, and leather. Materials use was a skills-based activity perfected by artists and guild-members handed from one generation to the next.

Attempts to determine the extent of cross-linking in wool fibers, whether untreated or reduced and alkylated, by measurement of swelling in aqueous LiBr or similar solvents (Haly, 1963a Atkinson and Speakman, 1960 Speakman and Stone, 1962, 1963) give results of doubtful significance because of the inhomogeneity of the wool fiber.
