In the caption of the cover photograph for 25 May 1973, the word "below" is misplaced; it should be deleted from the first sentence, and the second sentence should read: "(Below) Same view taken through a cylindrical lens . . ." Two errors occurred in the report by Freeman and Thibos in the same issue, p. 876: in column 2, line 4, "Freeman and co-workers" should be changed to "Freeman et al." in column 3, line 44, "the visual resolution" should be changed to "visual resolution"-Ed.  相似文献

The cover caption for the issue of 9 February 1990 should have described the molecule on the cover as VPI-5 (Dow and Virginia Polytechnic Institute), not as ALPO-5 (Union Carbide). The first sentence of the caption should have read, "Superlattices of p-nitroaniline molecules self-assemble and orient within the polar, greater than 10 angstrom wide channels of VIP-5, a molecular sieve." The preferred orientation of the polar molecules occurs in both materials.  相似文献

Transient events observed since 1980 by the Gamma-Ray Spectrometer experiment on the Solar Maximum Mission satellite (SMM) have been identified with radiation emitted from 18 different Soviet nuclear reactor-powered satellites. Most of these satellites are similar to Cosmos 954 and 1402 which reentered the atmosphere. Gamma radiation from these satellites was detected when they passed within about 400 to 500 kilometers of SMM. Positron annihilation line radiation (511 kiloelectron volts) and charged-particle events were detected when SMM encountered clouds of positrons and electrons emitted by these satellites and stored up to tens of minutes in the geomagnetic field. The rate of these events varied from about 1 in 5 days to over 30 per day and was strongly dependent on the operating altitudes of the Cosmos satellites and density of the upper atmosphere.  相似文献

In Eliot Marshall's article "California's debate on carcinogens" (News & Comment, 20 Mar., p. 1459), the last sentence of the third paragraph, which refers to fines to be imposed under Proposition 65, should have read, "Companies found guilty of violating it will be charged $2500 a day and legal costs." The article gave the incorrect figure of "$25,000 a day."  相似文献

In equation 6 of the Research Article "Effects of age on dopamine and seratonin receptors measured by positron tomography in the living human brain" by D. F. Wong et al. (21 Dec., p. 1393) C(p)(t) in the denominator of the last term should have been A(cb)(t). This does not affect the rest of the derivation. In the caption of figure 1, the first word, "Decrease," should have been "Change." The data in parts A and B of figure 3 should have been regraphed on common axes to facilitate comparison. A corrected figure 3 is shown below.  相似文献

In the report "Induction of hemoglobin accumulation in human K562 cells by hemin is reversible" by A. Dean et al. (24 Apr., p. 459), the second sentence in the legend for figure 1 should have read: "A stock solution of 600 microM hemin was prepared by adding 0.3 ml of 1N NaOH to 19.56 mg of hemin, and then adding 0.3 ml of 0.5M tris base, 2.5 ml of cell growth medium, and 0.35 ml of 1N HCI, and then diluting to a final volume of 50 ml with cell growth medium."  相似文献

In Bernard D. Davis' article "Bacterial domestication: Underlying assumptions" (Policy Forum, 13 Mar., p. 1329), the word "no" was erroneously omitted from the last sentence of the first full paragraph in column two on page 1334. The sentence should have read, "But this view builds on a parallel between genetic engineering and the physical technologies, rather than on a much closer model, with very different predictions: the domestication of wild organisms, resulting in enormous benefits and no catastrophes."  相似文献

Due to a printer's error, the word "nitrite" was altered to "nitrate" in two instances in the article, "Ever so cautiously, the FDA moves to-ward a ban on nitrites," (8 September, p. 887). The lead sentence should read," The hazard to animals and man of eating excessive amounts of nitrates and nitrites...." The first sentence in the fourth paragraph should read," These circumstances ... the existent but unquantified hazard of adding nitrites to food." Nitrites-not nitrates-are deliberately added to foods.  相似文献

In the report "Peroxisomal defects in neonatal-onset and X-linked adrenoleukodystrophies" by S. Goldfischer et al. (4 Jan., p. 67), the first sentence of the abstract should have read: "Accumulation of very long chain fatty acids in X-linked and neonatal forms of adrenoleukodystrophy (ALD) appears to be a consequence of deficient oxidation of very long chain fatty acids, a function that has been attributed to peroxisomes."  相似文献
