A method of sampling coarse river‐bed material

, 1954
This determination of the size of material on the bed of a stream is based upon an analysis of the relative area covered by particles of given sizes. The method is applicable to those rivers which flow on coarse material and may be waded during periods ...

Sites, Sampling, Materials and Methods

2019
The overall methodological approach of this thesis is to combine 15N-SIP mesocosm experiments with a field plot 15N tracing experiment in order to gain a better understanding of the microbial processing of fertiliser N in soils at a biomolecular level and relate this to the situation in a field environment in which physical partitioning and transport ...

Materials Handling for Bulk Sampling

1952
Tremendous amounts of materials in bulk lots pass from vendor to vendee, and millions of dollars are paid out daily by purchasers, on the basis of the average quality of the products being exchanged. Continuous manufacturing processes are developed and their operations calculated on the basis of the average quality of the raw materials fed into the ...

The role of sustainable materials in sample preparation

Analytical and Bioanalytical Chemistry, 2023
Sample preparation is a constantly evolving step in the measurement process with a positive effect on its performance. Its evolution has been marked by an underlying environmental commitment, with simplification, miniaturization, and automation being three of its driving forces.

EVALUATION OF MUFFLER MATERIAL SAMPLES

1966
Abstract : A practical heat-corrosion test, with respect to time, was designed to evaluate the corrosion resistance of various coated and noncoated muffler materials. Basically, the test is a modification of the Chrysler test used by industry. The duration of the test was shortened from 250 hours to 8 hours.

Statistical Theory in Materials Sampling

Journal of the Construction Division, 1971
To assess construction quality and establish process control specification limit, governing organizations can use statistical analysis in materials sampling and testing. Inspecting costs and construction time-delays can be minimized with the assistance of statistical theory applications to establish the degree of variability for various items of ...
