Abstract: Peptide antimycotics, termed pseudomycins, display broad spectrum antibiotic activity, and in particular are highly effective, non-toxic antibiotics against fungal pathogens of human and animal disease. The peptide antimycotics (pseudomycins) may be used in the treatment of the fungal pathogen Candida albicans. Also disclosed is a method of purification and isolation, including characterization, of the pseudomycins.

Abstract: PWM converters provide buck, boost, buck-boost, flyback, and Cuk configurons for three phase AC-AC power control. In an AC-DC embodiment, only a single power conversion circuit is used in a configuration including a pair of series connected gate turn off devices which are oppositely poled and oppositely timed, are connected directly to an AC input source, and provide an output to a high frequency isolating transformer. The transformer provides an output to a rectifier, which thus provides the DC output.

Abstract: A broad spectrum biological herbicide comprises a mammal-sparing bioherbicide fungal mutant, e.g., a S. sclerotiorum mutant, of limited survival time and geographical dissemination characteristics under standard agricultural conditions. The invention also relates to a method of obtaining herbicides of the invention comprising obtaining viable wild type bioherbicide fungal spores, subjecting these to UV light to reduce the number of viable fungi to less than 5% the initial number of spores, selecting mutants which differ from the wild type in at least one characteristic such as altered phenotype or morphology, and further selecting a mammal-sparing bioherbicide fungal mutant of reduced survival time and geographical dissemination characteristics under agricultural conditions when compared with the wild type. The invention also relates to a method of using the broad spectrum biological herbicide to reduce the number of weeds in an area.

Abstract: A system for detecting and locating faults on a power system includes the e of fault detection and transmitting devices on each pole of the system. The fault detection apparatus includes detecting coils mounted on the static line on either side of each pole, and a third detecting coil positioned so as to detect an orthogonal magnetic flux due to a phase-to-phase fault. A microprocessor on each pole analyzes the type of fault from the output of the three coils, and transmits the identification of the pole and pertinent fault data, when appropriate, to a repeater system. Thus, fault information from an entire power system can be fed through the repeater system into a central location.

Abstract: Taxol is produced from a taxol-producing microorganism Taxomyces andreanae BS 279.92. Radioactive taxol products and methods for use of the radioactive labelled taxol are described.

Abstract: Preparations from aromatic plants that are insecticidal or are insect behaviorally active, are used to control the development of insect populations. The plants are harvested after leaf maturation. Leaves are removed in a random pattern both as to individual plants and to location of leaves on each plant. The collection includes petioles but not stems. Leaves are milled with or without drying to a small average particle size. Extracts and vapors may also be used. The resultant preparation, when contacted with dry commodities infested with storage insects or with insect infested perishable produce after harvest will reduce the insect population.

Abstract: An apparatus and method for measuring the buffering capacity of a liquid which utilizes a pH electrode positioned at the surface of a working electrode. Measured changes in pH of the metal-water interface at known potentials which are applied to the working electrode are used to calculate the liquid buffering capacity.

Abstract: An apparatus and method for measuring the buffering capacity of a fluid which utilizes a pH electrode that is positioned at the surface of a smooth metal working electrode. Measured changes in pH of the metal-water interface at known potentials which are applied to the working electrode are used to calculate the fluid buffering capacity.

Abstract: DL-methionine is fed to a ruminant animal in slow release form so as to stimulate protein growth in the first stomach or rumen and thus control growth of the animal.

Abstract: A method of selectively inducing chlorosis on a knapweed plant while spar other plants comprises applying a knapweed phytotoxic amount of the L,L isomer of the cyclodipeptide of the invention to a field at a period in time prior, during or subsequent to the emergence of the plants; and allowing for the cyclodipeptide to remain in contact with the plants for a period of time effective to attain the phytotoxic effect.

Abstract: A non-destructive method for the early detection of the formation of orga deposits or a biofilm on the internal surface of a conduit through which a fluid passes comprises allowing the fluid to flow through a conduit, passing a light beam, e.g., IR or UV light, through the fluid and the deposits in a direction transversal to the surface thereof, detecting and measuring the transmitted portion of the light beam after it has emerged from the fluid and the deposits, conducting these measurements at least twice at a set time interval, the first time before any materials deposit, and calculating % variation absorbed light during the time interval, which value is proportional to the organic materials or biofilm deposited and a method of removing at least a portion of organic deposits or a biofilm deposited on the internal surface of a conduit through which a fluid flows comprises allowing the fluid to flow through a conduit having a deposited organic layer or biofilm, passing a light beam, e.g.

Abstract: Mutant microorganisms comprising Lactobacillus ferementum Lex.sup.+ which are obtained from Lactobacillus fermentum produce lysine in a significantly greater quantity than the wildtype microorganism. The microorganism is added to a sourdough starter to produce bread of increased nutritive content, such as flat bread. Freeze-dried cultures of the microorganism may be added to cereal grains such as wheat in bulk to increase the basic nutritive protein quality of the wheat, whereby foodstuffs produced from the cereal grains have increased protein values.

Abstract: Beneficial growth of roots in dicotyledonous plants is achieved by genetic transformation with root-inducing A. rhizogenes, preferably the novel strain A. rhizogenes ATCC 39207. The A. rhizogenes not used to transform the plant is reduced to noninfective levels with A. radiobacter, preferably A. radiobacter K-84.

Abstract: A novel agriculturally useful composition that includes a seed treated with selected infectivity-cured Hr plasmid-bearing microorganism. Also provided are methods of enhancing root elongation, shoot elongation or root development of selected seeds. These methods include treating a selected seed with the infectivity-cured Hr plasmid-bearing microorganism. In addition, there is provided a method of inducing germination of grass seed that involves treating a grass seed such as Kentucky bluegrass seed with a selected infectivity-cured Hr plasmid-bearing microorganism. Furthermore, there is provided a method of promoting plant growth at a lower soil temperature than is common at the time of planting a seed of the plant.

Abstract: The invention provides an improved method and apparatus for reduction of matrix interference in an electrothermal atomizer for atomic absorption spectroscopy. In a carbon rod atomizer within which a sample to be analyzed is atomized to the atomic state, the graphite furnace tube is electrothermally heated from the ends to the center where the sample is located. This provides sufficient thermal energy for complete decomposition of the sample molecules to the atomic state. In a first apparatus embodiment two-pronged substantially Y-shaped graphite electrode support holders for the graphite furnace tube are provided. In a second apparatus embodiment a double-walled graphite furnace tube is provided.
