Water and methanol adsorption isotherms at 25° and 37° C.
were determined on a series of organo-bentonite clays. The clays
differed in the length of the carbon chain attached to the amine adsorbed
in the cation exchange position. The amines used had carbon
chains of 4, 6, 8, 10, 12,...
Studies of δ¹⁸O held in freshwater bivalve shell carbonate are useful for reconstructing paleoclimates and environmental changes and inform interpretations about past human behavior and periods of culture change. Stable isotope analyses (δ¹⁸O) of Margaritifera falcata shells found at the Cooper's Ferry archaeological site located in the lower Salmon River...
Soil is a valuable medium when investigating the past-- from understanding rates of development, landform evolution, to the construction of various predictive models. Landforms and sediments provide insight into depositional environments and soil morphology indicates pedogenic change within those landforms. The rate at which pedogenesis occurs has been quantitatively measured...
There is no doubt that adhesive penetration plays an important role in wood bondline joint performance and durability; yet, to date there is no direct experimental evidence linking penetration depth with bond performance. This is, in part, because adhesive penetration is commonly assessed with various 2D microscopy techniques that are...

The purposes of this study were to determine the effects of
temperature, nutrients, growth regulators, and culm detachment
during seed development on ryegrass seed dormancy and weight.
The effects of storage temperature on seed dormancy were also
studied.
Seed dormancy of annual (Lolium multiflorum Lam.) and
perennial (Lolium perenne L.)...
An enabling technology for long duration, deep space missions is the availability of a high power, long-lived power supply. The goal of this work is the design of a self-regulating deep space nuclear reactor. The design objectives are to produce 250 kWth for a 25-year period using the presence of...
The impact that Andrew Tate has on his audience paired with the platform he holds has made Andrew Tate one of the most infamous names related to misogyny and “male empowerment”. His ability to connect to his audience and convince them of the superiority of his beliefs allows him to...
A herd of California bighorn sheep (Ovis canadensis californiana),
re-introduced to the area of Hell Creek on the Sheldon National
Wildlife Refuge in northwestern Nevada, was studied from 15 June 1978
to 20 August 1980.
Major vegetation and physiographic types were delineated and
described. Habitat preferences were determined from field...
Approximately 2700 years ago, Greek settlers from the Northwestern Peloponnese region of Achaea emigrated to the central coast of Southern Italy along the Gulf of Taranto. The city they founded, Metapontum, served as an important center for Magna Graecia, the lands on the Southern Italic peninsula wholly populated by Hellenic...
