Air weight

The table which follows gives the values of k (buoyancy reduction factor), which is the correction necessary because of the buoyant effect of the air upon the object weighed the table is computed for air with the density of 0.0012 m is the weight in grams of the object when weighed in air weight of object reduced to in vacuo = m + m/1000. 

LARC-TPI is a linear thermoplastic PI which can be processed ia the imide form to produce large-area, void-free adhesive bonds. Mitsui Toatsu Chemicals, Inc., has obtained Hcense to produce this product commercially for appHcations such as adhesives, films, mol ding compounds, etc. These are thermooxidatively stable and show essentially no loss ia weight at 300°C ia air. Weight loss does not exceed 2—3% after isothermal aging ia air at 300°C for 550 h. 

Very pure docosanedioic acid can be obtained by another recrystallization from about 450 ml. of 2-methoxyethanol. The recrystallized acid is collected on a Buchner funnel, and the well-pressed filter cake is suspended in 200 ml. of 95% ethanol, refiltered, and dried in air weight 112 g. (61%) m.p. 126-127° neutralization equivalent, 185-187. 

Specific gravity = Weight in air/(Weight in air — Weight in water)... 

The weight in air/weight in water method is one of the traditional methods of specific gravity determination. Selected sample units are first weighed in air and then the same unit is re-weighed suspended in water. Typically a computerized apparatus is used, such as that described by Tai et al. (1985). A potato hydrometer which is used with a fixed weight of potatoes may also be used for this purpose.

The Bi content of plants has not been studied widely. Shacklette et al. (1978) found Bi in only about 15% of Rocky Mountain trees, with levels ranging from 1 to 15 Jgg air weight (AW). Similarly, Bowen (1987) reported mean Bi concentrations of < 0.02 Jgg dry weight (DW) in land plants, and 0.06 ppm DW in the edible parts of vegetables. Erametsa et al. (1973) found a range of Bi in Lycopodium sp. from <1 to 11 ppm DW, with about 60% detectability. Bi is likely to be concentrated at polluted sites due to its high con-...

The asphaltene eontent of the oil sample was deter mined by asphaltene preeipitation aeeording to ASTM Standard Method D 2007. The maltenes were blown dry using compressed air. Weight differenee was used in both instances to determine quantities. Only the nonvolatile portions of the oil were analyzed.

Low Volatility One of the least volatile hydroxy phenyl benzotriazoles commercially available. Onset of TGA when BB/200 is heated at lOC/min in air) weight loss is approximately 350C. Compared to competitive products which volatilize out of the polymer during high temperature processing, Mixxim BB/200 remains in the polymer to protect the finished product.
