TL;DR: The distribution of naturally occuring epiphytic populations of Xanthomonas campestris pv.
Abstract: The distribution of naturally occuring epiphytic populations of Xanthomonas campestris pv. phaseoli on individual leaves of dry beans was assessed by various graphical and statistical techniques. Population sizes of X. c. phaseoli were estimated from the number of characteristic colonies formed on MXP medium. Data sets that contained 20 or 100 leaves and supported detectable numbers of X. c. phaseoli departed significantly from normality. Logarithmic transformation failed to result in normal distribution of data. The flexible Weibull distribution was selected as a possible alternative to normal and lognormal distributions for fitting censored and uncensored data sets (...)

TL;DR: Xanthomonas campestris pv.
Abstract: In two experiments, initiated in 1986 and 1987 in the Dominican Republic, Xanthomonas campestris pv. phaseoli, the causal organism of the common blight disease of dry beans (Phaseolus vulgaris), survived in surface debris composed of diseased leaves. In contrast, leaves in plastic mesh bags located at a depth of 15 cm were apparently decomposed and devoid of the pathogen in less than 30 days. After extraction of bacteria from debris using 12.5 mM potassium PO 4 buffer (pH 7.1) with 1 mM MgSO 4 , dilutions were made and plated onto MXP medium

TL;DR: The number of citations listed for both pertinent people and papers as provided by the Science Citation Index is used as one of a large number of criteria on which to base decisions about recognition of scientists at or near the Nobel Prize level.
Abstract: tee, I have extensive experience in assembling criteria that are used to accord recognition to scientists at or near the Nobel Prize level. We use the number of citations listed for both pertinent people and papers as provided by the Science Citation Index as one of a large number ofcriteria on which to base our decisions. I must believe that responsible, intelligent people in comparable positions who are assessing research performance by university departments would act in a similar fashion, and I only hope that the out-of-hand rejections described in the aforementioned article are not really the position of the people involved but repre-
