Degradation of Phenolic Acids by Azotobacter Species Isolated from Sorghum Fields

Description: Sorghum plants excrete phenolic acids which reduce subsequent crop yields. These acids accumulate in field soil by combining with soil and clay particles to form stable complexes which remain until degraded by bacterial metabolism. The amount of phenolic acids in soil samples were obtained by gas chromatography measurements, while Azotobacter populations were obtained by plate counts in 40 sorghum field samples from Denton County, Texas. One can conclude that increasing the Azotobacter populati… more

Characterization of the OCT Plasmid-Encoded Mercury Resistance Genetic Locus in Pseudomonas putida

Description: A 17.1 Kb genetic element encoding for mercury resistance (OCT-Hg^r) was shown to translocate from its original location on the OCT plasmid to the resistance plasmid, RPl, in Pseudomonas putida. Analysis of RPl-Hg^r recombinant plasmids revealed that insertion of mercury resistance genes into RPl could occur at a variety of sites, with all recombinants having common EcoRI restriction fragments of 9.4, 3.8, 2.3, and 1.6 Kb, derived from the insertion. Hybridization analysis suggested the existen… more

Act I, Scene 2 of Hamlet: a Comparison of Laurence Olivier's and Tony Richardson's Films with Shakespeare's Play

Description: In act I, scene 2 of Shakespeare's Hamlet, one of the key themes presented is the theme of order versus disorder. Gertrude's hasty marriage to Claudius and their lack of grief over the recent death of King Hamlet violate Hamlet's sense of order and are the cause of Hamlet's anger and despair in 1.2. Rather than contrast Hamlet with his uncle and mother, Olivier constructs an Oedipal relationship between Hamlet and Gertrude--unsupported by the text--that undermine's the characterization of Hamle… more

The Object-Oriented Database Editor

Description: Because of an interest in object-oriented database systems, designers have created systems to store and manipulate specific sets of abstract data types that belong to the real world environment they represent. Unfortunately, the advantage of these systems is also a disadvantage since no single object-oriented database system can be used for all applications. This paper describes an object-oriented database management system called the Object-oriented Database Editor (ODE) which overcomes this d… more
