Say! Dis Is Grate Stuff : The Yellow Kid and the Birth of the American Comics
On 12 December 1992, before a gathering of the Syracuse University Library Associates, Professor Olson delivered the keynote address that marked the opening of the University Library\u27s Yellow Kid exhibition. The following is an edited transcript of Olson\u27s talk.
What happened nearly one hundred years ago to give birth to the American comics? Who can we thank for having a colorful Sunday comic section to read every week? My analysis ofthe birth of the American comic strip suggests that it occurred as a result of the interaction of three major factors: (I) the natural evolution of graphic humor, (2) quirks of American history, and (3) Richard Fenton Outcault. In what follows we shall take a brieflook at these factors and see how they contributed to the birth ofthe comic strip
Frequency of Resistance to Bacillus thuringiensis Toxin Cry1Ab in an Iowa Population of European Corn Borer (Lepidoptera: Crambidae)
The refuge plus high-dose strategy for resistance management assumes that the frequency of resistance alleles is low. We used an F2 screen to estimate the frequency of resistance to transgenic corn that produces Bacillus thuringiensis Berliner Cry1Ab toxin (Bt corn) in an Iowa population of European corn borer, Ostrinia nubilalis (Hu¨ bner). We also proposed a modiÞcation to the statistical analysis of the F2 screen that extends its application for nonuniform prior distributions and for repeated sampling of a single population. Based on a sample of 188 isofemale lines derived from females caught at light traps during the 2nd ßight of 1997, we show with 95% conÞdence that the frequency of resistance to Bt corn was ,3.9 3 1023 in this Iowa population. These results provide weak evidence that the refuge plus high-dose strategy may be effective for managing resistance in O. nubilalis to Bt corn. Partial resistance to Cry1Ab toxin was found commonly. The 95% CI for the frequency of partial resistance were [8.231024, 9.431023] for the Iowa population. Variable costs of the method were $14.90 per isofemale line, which was a reduction of 25% compared with our initial estimate
Flight simulator with spaced visuals
A flight simulator arrangement wherein a conventional, movable base flight trainer is combined with a visual cue display surface spaced a predetermined distance from an eye position within the trainer. Thus, three degrees of motive freedom (roll, pitch and crab) are provided for a visual proprioceptive, and vestibular cue system by the trainer while the remaining geometric visual cue image alterations are developed by a video system. A geometric approach to computing runway image eliminates a need to electronically compute trigonometric functions, while utilization of a line generator and designated vanishing point at the video system raster permits facile development of the images of the longitudinal edges of the runway
Characterization of radiolytically generated degradation products in the strip section of a TRUEX flowsheet
This report presents a summary of the work performed to meet the FCRD level 2 milestone M3FT-13IN0302053, “Identification of TRUEX Strip Degradation.” The INL radiolysis test loop has been used to identify radiolytically generated degradation products in the strip section of the TRUEX flowsheet. These data were used to evaluate impact of the formation of radiolytic degradation products in the strip section upon the efficacy of the TRUEX flowsheet for the recovery of trivalent actinides and lanthanides from acidic solution. The nominal composition of the TRUEX solvent used in this study is 0.2 M CMPO and 1.4 M TBP dissolved in n-dodecane and the nominal composition of the TRUEX strip solution is 1.5 M lactic acid and 0.050 M diethylenetriaminepentaacetic acid. Gamma irradiation of a mixture of TRUEX process solvent and stripping solution in the test loop does not adversely impact flowsheet performance as measured by stripping americium ratios. The observed increase in americium stripping distribution ratios with increasing absorbed dose indicates the radiolytic production of organic soluble degradation compounds
A consistent derivation of the quark--antiquark and three quark potentials in a Wilson loop context
In this paper we give a new derivation of the quark-antiquark potential in
the Wilson loop context. This makes more explicit the approximations involved
and enables an immediate extension to the three-quark case. In the
case we find the same semirelativistic potential obtained in
preceding papers but for a question of ordering. In the case we find a
spin dependent potential identical to that already derived in the literature
from the ad hoc and non correct assumption of scalar confinement. Furthermore
we obtain the correct form of the spin independent potential up to the
order.Comment: 30 pages, Revtex (3 figures available as hard copies only), IFUM
