Relationships between fresh weight, dry weight, ash free dry weight, carbon and nitrogen content for selected vertebrates

Journal of Experimental Marine Biology and Ecology, 2016
Top predators are relevant indicators of the ecological status of a system and can have a high impact on food webs. But top predators are difficult to include in network analyses because their biomass in ash free dry weight or carbon content ismissing.

DRYING LIGHT-WEIGHT CONCRETE SLABS

Chemical Engineering Communications, 1986
To study unsteady state problems of heat and mass transfer in concrete pavements, which are generally considered to be fine porous media, both relevant material characteristics and transport properties must be considered simultaneously. A system of nondimensional differential equations for heat and mass transfer in porous media is derived and used to ...

The relation of rat liver wet weight to dry weight

Histochemistry, 1985
To assess a reliable relation between the dry and wet weight of rat livers, the water content of liver samples was determined by freeze drying. The ratio between wet and dry weight of the livers turned out as 3.33 +/- 0.3 for male and 3.28 +/- 0.24 for female rats. Thus for calculations a value of 3.3 can be used irrespective of the sex of rats.

The Dry Weight of Wool

Textile Research Journal, 1959
A study has been made of the drying of wool in vacuo. The time required to reach the equilibrium weight decreases with increasing temperature of drying, and the equilibrium weight decreases with increasing temperature up to 140° C. The equilibrium weight obtained in vacuo is less than the weight obtained in air under the same conditions.

Should foliar cadmium concentrations be expressed on a dry weight or dry ash weight basis?

Journal of Environmental Monitoring, 2002
Foliar analysis is a valuable tool for evaluating the pollution status of forests. However, the use of foliar diagnosis in large-scale surveys is a complicated process owing to the high variability within the crown. The method used to express foliar concentrations has often been found to diminish the variability.

Determining dry weight and percentage dry matter of chironomid larvae

Canadian Journal of Zoology, 1974
Reproducible live wet weights may be obtained for medium to large larvae of Metriocnemus knabi and Chironomus attenuatus after blotting them on filter paper for 1 min. To obtain reliable measures of wet weight for smaller larvae the blotting time must be reduced in proportion to the surface area/volume ratio of the larvae.

Dry weight in children on hemodialysis

Giornale di Tecniche Nefrologiche e Dialitiche, 2015
An accurate assessment of dry-weight (DW) is critical in children on chronic hemodialysis (HD) to avoid the risk of both volume overload and volume depletion. It requires a comprehensive evaluation, which includes clinical history, physical examination and diagnostic tools, such as bioimpedance analysis and non invasive volume monitoring.

Sampling and predicting tree dry weight

Canadian Journal of Forest Research, 1993
Procedures and formulae are given for modeling and sampling ovendry weight of a tree bole. The models are derived from first principles, and importance sampling ideas are used to develop methods for sampling individual trees to obtain unbiased estimates of dry weight. These methods would be particularly useful for providing sample estimates of the dry

Dry Weight of Several Piedmont Hardwoods

Journal of Forestry, 1968
Abstract Forty-four sample hardwood trees felled on 24 plots were separated into three above-ground components–stem, branches, and leaves–and weighed for dry matter content. Tree, stand, and site variables were tested for significant relationships with dry weight of tree parts. Weight increase of stems was a logarithmic function of both
