Predatory Prokaryotes: Predation And Primary Consumption Evolved In Bacteria, Lynn Margulis, Ricardo Guerrero, Carlos Pedrós-Alió, Isabel Esteve, Jordi Mas, David Chase Apr 1986

Predatory Prokaryotes: Predation And Primary Consumption Evolved In Bacteria, Lynn Margulis, Ricardo Guerrero, Carlos Pedrós-Alió, Isabel Esteve, Jordi Mas, David Chase

Lynn Margulis (1938 - 2011)

Two kinds of predatory bacteria have been observed and characterized by light and electron microscopy in samples from freshwater sulfurous lakes in northeastern Spain. The first bacterium, named Vampirococcus, is Gram-negative and ovoidal (0.6 μm wide). An anaerobic epibiont, it adheres to the surface of phototrophic bacteria (Chromatium spp.) by specific attachment structures and, as it grows and divides by fission, destroys its prey. An important in situ predatory role can be inferred for Vampirococcus from direct counts in natural samples. The second bacterium, named Daptobacter, is a Gram-negative, facultatively anaerobic straight rod (0.5 × 1.5 μm) with a single …


Northern Hemisphere Surface Air Temperature Variations: 1851-1984, P. D. Jones, S. C. B.Raper, Raymond S. Bradley, H. F. Diaz, P. M. Kelly, T. M. L.Wigley Feb 1986

Northern Hemisphere Surface Air Temperature Variations: 1851-1984, P. D. Jones, S. C. B.Raper, Raymond S. Bradley, H. F. Diaz, P. M. Kelly, T. M. L.Wigley

Raymond S Bradley

A new compilation of monthly mean surface air temperature for the Northern Hemisphere for 1851-1984 is presented based on land-based meteorological station data and fixed-position weather ship data. This compilation differs from others in two ways. First, a considerable amount of new data, previously hidden away in archives, has been included, thus improving both spatial and temporal coverage. Second, the station data have been analyzed to assess their homogeneity. Only reliable or corrected station data have been used in calculating area averages. Grid point temperature estimates have been made by interpolating onto a 50 latitude by 100 longitude grid for …


Analytical Applications Of Absorption Spectroelectrochemistry At Grazing Incidence, Julian Tyson Jan 1986

Analytical Applications Of Absorption Spectroelectrochemistry At Grazing Incidence, Julian Tyson

Chemistry Department Faculty Publication Series

Analytical applications of spectroelectrochemistry are limited by the short path-length, in the absorbing medium, that can be produced with most light-beam/electrode configurations. This disadvan­tage is overcome for grazing incidence. A cell fitted with glassy-carbon electrodes and used in a conventional spectrophotometer is described and applied to model systems illustrating the use of (a) homogeneous redox reactions, (b) homogeneous redox reaction followed by chemical reaction and (c) electro-deposition followed by stripping into a reagent solution. This last technique is the spectro­electrochemical analogue of anodic-stripping voltammetry.


A Comparison Of Curve Fitting Algorithms For Flame Atomic Absorption Spectrometry, S. R. Bysouth, Julian Tyson Jan 1986

A Comparison Of Curve Fitting Algorithms For Flame Atomic Absorption Spectrometry, S. R. Bysouth, Julian Tyson

Chemistry Department Faculty Publication Series

A comparison of six commercially available curve fitting algorithms for calibration in flame atomic absorption spectrometry (FAAS) has been made. Programs using the algorithms were written in BAsrc for a microcomputer and, where possible, tested against the commercial version. Calibration curves for magnesium, chromium and nickel produced by the algorithms were compared, on the basis of the sum of squares of the percentage deviations and its root mean square, with each other and with linear interpolation and manual fitting. The standard deviations of the goodness of fit parameters were calculated to indicate significant differences between the fits obtained. With the …

Flow Injection Atomic Absorption Spectrometry: The Kinetics Of Instrument Response, J. M. H. Appleton, Julian Tyson Jan 1986

Flow Injection Atomic Absorption Spectrometry: The Kinetics Of Instrument Response, J. M. H. Appleton, Julian Tyson

Chemistry Department Faculty Publication Series

The concept of dispersion coefficient is discussed with particular reference to flow injection atomic absorption spectrometry where the detector contributes appreciably to the analytical signal characteristics. Single- and parallel-tank models of instrument response are developed and critically examined. The progress made to date by investigators of nebuliser performance is briefly reviewed prior to developing a semi-empirical extended-tank model of instrument response. The capabilities of this model are explored by deriving a set of equations for instrument response, and comparing the predictions with experimental results. Agreement is generally good. Advantages of the modelling approach are discussed.

A Variable Dispersion Flow Injection Manifold For Calibration And Sample Dilution In Flame Atomic Absorption Spectrometry, Julian Tyson, James R. Mariara, J. M.H. Appleton Jan 1986

A Variable Dispersion Flow Injection Manifold For Calibration And Sample Dilution In Flame Atomic Absorption Spectrometry, Julian Tyson, James R. Mariara, J. M.H. Appleton

Chemistry Department Faculty Publication Series

A flow injection (FI) introduction system for flame atomic absorption spectrometry (FAAS) has been constructed for single-standard calibration and sample dilution. Dilution factors ranging from 5.93 to 38.8 in six discrete stages were produced by replicate injection of 12.5-pl volumes into an aqueous carrier stream flowing down lines of different lengths. The dilution factors were measured for five different solutions for each line. No dependence on concentration was found and the relative standard deviations ranged from 0.75 to 3.1%. The manifold was evaluated by the analysis of solutions of magnesium (6,12.5 and 35 p.p.m.), nickel (180 p.p.m.), calcium (75 p.p.m.) …
