Computers for the Masses: The American Socio-technological Change of the 1970’s and 1980’s

Abstract

Computers for the Masses: The American Socio-technological Change of the 1970's and 1980's Robert Bryan Goodman This thesis developed out of my personal curiosity on the subject of high-technological development. Specifically, high-technology's shift from primarily a military tool to a consumer product raised several questions to answer since first taking an interest in the subject. My lifestyle, like many other Americans in my generation, incorporates computers, cell-phones, and video game consoles as not only an innovative tool, but a standard and necessary mode of production. In our contemporary society, technology is obtainable everywhere. As an

The influence of temperature on the MgO zone-axis pattern

“…For the present study patterns were taken at two well-defined temperatures at various points on the Kossel map with the 200 reflexion excited, to find phenomenological values for the Debye-Waller factor B, and V~. The latter results have been tabulated separately (Goodman & Johnson, 1970). At first a B factor for room temperature found from X-ray diffraction, and structure factors for the [001] projection published by Togawa (1964) which also agreed with the previous analysis (Goodman & Lehmpfuhl, 1967) were assumed.…”

“…high-contrast characteristic loss scattering, is therefore probably present in the measurement, so giving a lower V~ value than that for elastic scattering. The pattern measured was for the 082 line; with E =79kV, the values V~=0.6, 0.7 volt, were obtained for T= Tx and T= T2, respectively using the 4-beam calculation with V~, = 0.25 and 0.22, respectively (Goodman & Johnson, 1970).…”

“…More recent work has shown that, at least for MgO, this calculation gives the correct extinction length for certain orientations, but is much less helpful in interpreting the absorption measurements (Goodman & Johnson, 1970;. The zone-axis patterns would appear to have a great advantage due to their high symmetry.…”

“…At first a B factor for room temperature found from X-ray diffraction, and structure factors for the [001] projection published by Togawa (1964) which also agreed with the previous analysis (Goodman & Lehmpfuhl, 1967) were assumed. Later the B factor was confirmed from the analysis; also the previous method of analysis has been improved by calculations allowing corrections for accidental interactions, and by more accurate wavelength determination from the Kossel map ( Goodman & Johnson, 1970 Vnt=0"36 volt in (b).

Death in leopard geckos (Eublepharis macularius) following ingestion of vermiculite

“…Aluminium hydroxide is regarded as practically non-toxic in humans (Gosselin, 1976) however, large doses may lead to acute phosphate depletion (Rumack, 1980). Goodman (1980) stated that aluminium hydroxide may be absorbed from the gut and in humans with impaired renal function aluminium may accumulate in a variety of tissues. No references to toxicity of oral aluminium oxide were found.…”
