Illite, chlorite, montmorillonite and kaolinite, as well as
natural marine sediments and mixtures of the standards were subjected
to density separation by centrifugation in a linear heavy-liquid
gradient.
The density layers yielded by centrifugation were recovered
and analyzed by X-ray diffraction. Separates were not monomineralic
but rather were polymineralic usually...
The selective adsorption from a series of binary solutions on an
organoclay complex has been studied in relation to the gelling ability
of this organoclay. Adsorption isotherms were obtained for a series
of polar organic solvents in toluene. The isotherms were of the usual
"S" or "U" type depending upon...
Six organoclay complexes have been studied in terms of their
selective adsorption from binary solutions of methanol and toluene.
Analyses are based on differential refractometry methods. The
isotherms were of the usual "S" type. The crossover points reveal
trends in the organophilic nature of the interlaminar surfaces in
these clay...
The purpose of this study was to identify learning activities that
were both Future Homemakers of America/Home Economics Related
Occupations goal-related and realistic for use in the home economics
classroom. The hypothesis tested was: there is no significant difference
between mean scores of individual learning activities related
to FHA/HERO goals...
Ungulates comprise some of the most well researched and intensely managed wildlife populations on earth. As such, they are recognized as ideal study subjects for developing and modifying management tools or theories (Danell et al. 1994, Shipley 2010). An introduced moose (Alces alces gigas) population on the Copper River Delta...
The virtual reality (VR) experience War Remains created by Dan Carlin claims that it is an immersive memory in attempt to give its audience the “tiniest taste of” what-it-was-like to experience a WWI battle (Carlin, 2020). This claim aligns with the growing belief that VR can be the ultimate empathy...
