The transformation of sediment into berthierine is apparently progressive the initial sedimentary material found in shell tests becomes gradually transformed into a single phase, 7 chlorite structure. 

It is possible that the mechanism of berthierine formation in this example is one of accretion, i.e., the grain would accumulate material at the exterior and this is eventually transformed into a chlorite composition. None of the grains was noted to have the form of a shell test as is often noted glauconite pellets. However the meta-berthierine pellets reported by Velde, et al.. (1974), were often found inside foraminifera tests. 

Observations showed that the wind direction is not perpendicular to the cooling tower axis when a cooling tower is standing on a slope. To analyze pressure distributions on the inside and the outside face of the shell, tests were carried out at the Institut fuer Massivbau of the Technical University of Hannover to conduct the measurements of the inside and outside pressure distributions of an idealized cooling tower model in a wind tunnel and of perpendicular and nonperpendicular air stream to the model axis.

Finally, carbonate cements reveal the sources of dissolved carbon in the evolving pore waters of the San Joaquin basin. The clastic-rich basin is free of carbonate rocks but contains a considerable amount of organic matter, both in fine-grained sediment and as relatively recent hydrocarbon accumulations. Potential carbon sources for the carbonate cements are marine shell tests, thermogenesis and, possibly, organic reactions related to the presence of the oil. 

Isotopic analyses are measured on samples with a preponderance of either calcite or dolomite, based on X-ray diffraction. The samples were further high-graded by excluding samples with obvious mixtures of shell tests, cements, grain replacements...

Second, in the index to the test reports the shell tests are usually located in the section for the particular agent. A few examples were included but are omitted here. However, there are at least 35 such references to shell testing or firing tests. 

The LMU Munich research group has also been looking at tetrazole-free nitrogen-rich compounds that contain oxidizing groups such as nitramine functionalities. In this context, the preparation and structural characterization of dinitrobiuret (DNB) (Fig. 31) was carried out [109,110]. The high chemical and thermal stability of DNB and the determined critical diameter of 6 mm for DNB (Figs. 32, 33) in the Koenen test (steel shell test) is comparable to the values reported for HMX (8 mm), RDX (8 mm), or PETN (6 mm) and prompted us to obtain the thermodynamic data and detonation pressures and velocities for DNB in a combined experimental and theoretical study.

Victor Lefebure of Britain helped to organize the Inter-Allied Gas Conference in September 1917 in which Britain, France, and the United States shared information on gas research. The contingent from the United States was mostly a recipient of information rather than a contributor. Haber, The Poisonous Cloud, 131-32. The American Expeditionary Force also established a technical laboratory in Paris in January 1918, although its equipment arrived only in May. Sixty-five chemists, officers and enlisted, worked in the laboratory to inspect and evaluate German shells, test water supplies, and conduct various other analytical and practical research.

Description of hazard. A pressure vessel is a cylindrical or spherical metal container capable of withstanding pressures exerted by the contained material. Many liquids and gases must be stored under high pressure in such vessels. Safety codes have been developed that specify the container design for specified conditions, with special emphasis on the strength of the vessel to prevent rupture and subsequent explosions. All shells, test chambers, tanks, and model parts designed for internal pressures greater than 15 pounds per square inch (psi) are considered pressure vessels.
