چکیده
pletely clear, but it may be that all represent further examples of duplica. tion or reduplication of the same genie material. It is not possible at present to extrapolate the data of the lozenge series to other allelic series. However, they do not justify the conclusion that all multiple allelic series represent cases of multiple loci, for the simplest explanation for the situation within the lozenge complex itself would appear to be that of three closely linked multiple allelic series. Su)trnmry.-1. Crossing-over has been observed between three sexlinked, recessive lozenge alleles, IzBs, W6, Iz? in D. melunogasfer. 2. From females heterozygous for any two of the mutants, wild type X-chromosomes and X-chromosomes bearing two lozenge mutants have been recovered. 3. On the basis of the crossover results, the lozenge allelic series may be subdivided into three closely linked loci. :

Leo Szilard: a personal remembrance.
SINCE retiring as a full-time faculty member about ment of this building. Their plan was to study mutation in bacteria, and they looked for methods to measure 10 years ago, I have occupied myself with writing chronicles of past experiences. The first was an account mutation rates. At Cold Spring Harbor they had encountered Jacques of the advances made in the elucidation of gene expression and i...
متن کاملNonlinear population dynamics in the chemostat
tinuous stirred tank bioreactor, was independently invented by Jacques Monod1 and by Aaron Novick and Leo Szilard,2,3 who also coined the term chemostat. Its inventors conceived that this device provided a convenient way to study a bacterial population in the steady state, letting the experimenter adjust growth rate and external parameters, such as temperature or pH level. Novick and Szilard we...
متن کاملStructural, Optical and Ultra-Violet Photodetection Properties of ZnO Nanorods with Various Aspect Ratios
ZnO nanorods with various lengths were synthesized by a two-stage route (by changing the time of growth between 0-240 min) and were characterized using XRD, SEM, UV–Vis and PL techniques. The SEM and XRD results confirmed a fast growth of (0 0 2) plane in the preferential longitudinal orientation, in contrast to lateral growth and therefore, by increasing the time of hydrothermal growth, nanoro...
متن کامل2-Chlorophenol Removal of Aqueous Solution Using Advanced Oxidation Processes Resulting from Iron/ Persulfate and Ultra Violet/ Persulfate
Background: Advanced oxidation processes are used to remove toxic aromatic compounds with low biodegradability, such as 2-chlorophenol. This study investigates the use of Sulfate (SO4-) and persulfate (S2O82-) radicals, as one of the advanced oxidation methods, to remove 2- chlorophenol from aquatic solutions. Materials and Methods: This experimental and pilot-scale study was carried out usi...
