Resensitization to gibberellin of grand rapids lettuce seeds treated with continuous far red light

Mills, Ronald (Journal of the Tennessee Academy of Science, 1973)

Numerical Computation of the External Potential Field of the Isolated Active Purkinge Strand in a Volume Conductor

Harman, Thomas L. (SWIEECO Proceedings, 1973)

Abstract not available.

Effects of Intrinsic Region Width in SI(Li) p i n Diodes

Harman, Thomas L. (Solid State Electronics, 1974)

Description of certain effects related to the width of the intrinsic region produced in a silicon p-i-n diode by lithium ion drifting. It is found that for wider intrinsic regions at large forward biases there is a larger ...

A Comparison of Two Methods of Determining the Extracellular Potential Field of an Isolated Purkinge Strand in a Volume Conductor

Harman, Thomas L.; Harman, Thomas L. (IEEE Transactions, 1975-05)

The models considered in this study are those of Spach et al., [1], and Clark and Plonsey [6], [7]. Both assume circular cylindrical geometry for the isolated Purkinje strand and input information to the models consists ...

Minicomputers and Microprocessors

Harman, Thomas L. (IBM Corporation, 1976)

Abstract not available.

Volume Conductor Fields of the Isolated Axon

Greco, E. C.; Clark, J. W.; Harman, Thomas L. (Elsevier B.V., 1977)

A solution of Laplace's equation relating the transmembrane potential distribution of an active fiber in a volume conductor to its extracellular field distribution utilizing a Fourier-transform method [4] has been reformulated ...

Amino acid biosynthesis in isolated pea chloroplasts: metabolism of labeled aspartate and sulfate

Mills, Ronald (FEBS Letters, 1978)

Accumulating evidence points to chloroplasts as the site of nitrite and sulfate reduction and incorporation into carbon skeletons [I] Furthermore, several enzymes of aspartate-family amino acid biosynthesis recently have ...

Effects of lysine, threonine, and methionine on light-driven protein synthesis in isolated pea (Pisum sativum L.) chloroplasts

Mills, Ronald (Planta, 1978)

Light-driven incorporation of [14C]leucine (LEU) into protein in isolated pea chloroplasts was inhibited by 0.1 and 1 mM lysine (LYS), 0.1–10 mM threonine (THR) and 1 mM methionine (MET). Equimolar combinations of LYS plus ...

Experience with a Fourier Method for Determining the Extracellular Potential Fields of Excitable Cells with Cylindrical Geometry

Clark, J. W.; Harman, Thomas L.; Greco, E. C. (CRC Press, Inc., 1978)

In this chapter, well-known solutions that utilize a Fourier transform method for determining the extracellular, volume-conductor potential distribution surrounding elongated excitable cells of cylindrical geometry are ...

Itracellular localization of aspartate kinase in spinach (Spinacea oleracea)

Mills, Ronald (FEBS Letters, 1979)

1. Enzyme distribution between chloroplasts and the nonchloroplast parts of green leaf cells of Spinacia oleracea, Nicotiana rustica, Vicia faba, and Phaseolus vulgaris have been investigated by use of the nonaqueous ...

The isolation of a lysine sensitive aspartate kinase from pea leaves and its involvement in homoserine biosynthesis in isolated chloroplasts

Mills, Ronald (FEBS Letters, 1979)

Homoserine is an intermediate in the biosynthesis of the essential amino acids Thr and Met in microorganisms [I] and higher plants [2]. Pea seedlings synthesise massive amounts of Hse, mainly in the roots [3-51, although ...

Photosynthetic formation of the aspartate family of amino acids in isolated chloroplasts

Mills, Ronald (Plant Physiology, 1980)

The metabolism of 14C-labeled aspartic acid, diaminopimelic acid, malic acid and threonine by isolated pea (Pisum sativum L.) chloroplasts was examined. Light enhanced the incorporation of [14C] aspartic acid into soluble ...

A rapid method for isolation of purified physiologically active chloroplasts, used to study the intracellular distribution of amino acids in pea leaves

Mills, Ronald (Planta, 1980)

A procedure is described for the rapid (<5 min) isolation of purified, physiologically active chloroplasts from Pisum sativum L. Mitochondrial and microbody contamination is substantially reduced and broken chloroplasts ...
