Each lithic piece examined is recorded as to typological category, assigned a raw material type, and weighed.
The GLECC mixtures developed in this study utilize industrial wastes up to about 89% by volume of total solid matrix materials and weigh under 1850 kg/m3 (limit for lightweight concrete classification); yet their mechanical properties are similar to ultra-ductile ECC with added advantage of lower thermal conductivity for energy conservation when used as a building material.
During material handling and weighing, we observed higher airborne particle number concentrations of the hydrophobic CNMs (C60 and raw MWCNT) compared with hydrophilic CNMs.
In the next section, the pre-scaling area, different raw materials are received and weighed and sent to the mixing area.
The fermented material was manually homogenized and weighed (around 1 g) and the extraction buffer was added in the proportion of 1 : 10 (w/w).
One means of accomplishing that would be to include lab chiefs' safety records among the materials submitted in grant proposals (and weighed in funding decisions), alongside currently required materials such as human subjects and vertebrate-care documentation.
The sample retrieved from the envelope addressed to Mr. Leahy, chairman of the Judiciary Committee, at his Senate office address contained as much material as a sugar packet and weighed about a gram.
The plant material was dried at 65 °C and weighed to measure the dry aboveground biomass.
Five weeks later, the regenerated material was weighed and sampled, and transferred to new Petri dishes on top of pre-wetted and pre-weighed Whatman filter papers containing RD2 medium [ 47] containing full strength MS salts, MS vitamins, 10 mg l-1 ascorbic acid, 100 mg l-1 myo-inositol and 1 μM 6-benzyladenine for further maturation and development of somatic embryos.
The culprits: slowing growth in China, a voracious buyer of commodities, and a U.S. housing recession that, he says, will slash demand for building materials like copper and weigh down the global economy.
