He himself was asked his opinion on the matter one time but Hagan's name was not mentioned. Offering a list of men who correspond with one another but who receive their information from Keohane at Gill's; he will warn Keohane � they are J. O'Donnell, M. Moloney, J. O'Shea, R. O'Moore, P. Dunne. He stays with Fr. [Tirney] who speaks very well of Hagan. The Bishop of Limerick, whom he met, spoke in praise of 'Scotus'

The definitive publisher-authenticated version A D Rawlins. A bifurcated circular waveguide problem. J.I.M.A. 54 (1995) 59-81. Oxford University press is available online at: http://imamat.oxfordjournals.org/cgi/reprint/54/1/59.pdfA rigorous and exact solution is obtained for the problem of the radiation of sound from a semi-infinite rigid duct inserted axially into a larger acoustically lined tube of infinite length. The solution to this problem is obtained by the Wiener-Hopf technique. The transmission and reflection coefficients, when the fundamental mode propagates in the semi-infinite tube, are obtained. The present results could be of use for exhaust design, and as a possible instrument for impedance measurement

A note on Wiener-Hopf matrix factorisation
No full textThis is a pre-copy-editing, author-produced PDF of an article accepted for publication in Quarterly Journal of Mechanics and Applied Mathematics following peer review. The definitive publisher-authenticated version Rawlins, A D (1985). A note on Wiener-Hopf matrix factorisation. Quarterly Journal of Mechanics and Applied Mathematics. 38 (3) 433-437 is available online at: http://qjmam.oxfordjournals.org/cgi/reprint/38/3/433.pdfIn this paper the most general class of 2 x 2 matrices is determined which permit a
Wiener-Hopf factorization by the procedure of Rawlins and Williams (1). According
to this procedure, the factorization problem is reduced to a matrix Hilbert problem
on a half-line, where the matrix involved in the Hilbert problem is required to have
zero diagonal elements
Letter re: book
No full textLetter from Lucille M. Rawlins to Amon Carter regarding a book of newspaper clippings for Betty Rogers, widow of Will Rogers.805 W. 23rd St. Austin, Texas, Aug. 21, 1936. Mr. Amon G. Carter, Fort Worth Star-Telegram, Fort Worth, Texas. My dear Mr. Carter: Several days after the tragic news of the passing of our beloved friend Will Rogers was brought to use, I planned a book of newspaper articles on his death and subsequent events relating to him. On this Memorial Day in Fort Worth dedicated to him, I would be very happy if Mrs. Rogers would accept this book - as a token of our love and continued interest in everything pertaining to him. I made this book of whole sheets rather than clippings in order not to sacrifice parts of articles. These papers are taken from Ft. Worth, Dallas, several valley towns, Arkansas, and even Tennessee. A year after his leaving us his memory is still fresh in the minds of those who loved him as is evidenced by any news about him being front page news. I thank you for your kindness in seeing that Mrs. Rogers receives this book. Very sincerely yours, (Miss) Lucille M. Rawlins (Spanish Teacher, Robert Lee Paschal High School, Fort Worth)
The method of finite-product extraction and an application to Wiener-Hopf theory
No full textCopyright @ The Author, 2011. The publisher version of the article can be accessed at the link below.In this work we describe a simple method for finding approximate representations for special functions which are entire transcendental functions that can be represented by infinite products. This method replaces the infinite product by a finite polynomial and Gamma functions. This approximate representation is shown in the case of Bessel functions to be very accurate over a large range of parameter values. These approximate expressions can be useful for finding the roots of a transcendental equation and the Wiener-Hopf factorization of functions involving such Bessel functions.The method is shown to be potentially useful for other transcendental andWiener-Hopf problems, which involve other entire functions that have infinite product representations

Can a paleosol be used as a reference material for monitoring soil aggregate stability?
No full textAn important physical indicator of soil quality, which regulatory authorities may wish to monitor, is aggregate
stability. In a recent study, Rawlins et al. (in press) presented a novel method for determining the stability of aggregates
in water using a laser granulometer (LG). The LG is used to make two measurements of the continuous
size distribution (<2000 μm) within a sample of aggregates. The first measurement is made on water stable aggregates
after these have been added to circulating water (initial air-dried aggregate size range 1000 to 2000 μm). The
second measurement is made on the disaggregated material after the circulating aggregates have been disrupted
with ultrasound (sonication). The difference between the mean weight diameters of these two size distributions
is referred to as the disaggregation reduction (DR; μm). Soils with more stable aggregates, which are resistant
to both slaking and mechanical breakdown by the hydrodynamic forces during circulation, have larger values of
DR. Rawlins et al showed that for two soil types, the DR values had coefficients of variation of 12.1 and 19%
suggesting the DR value is reproducible based on the small mass of soil used. If such a test is to be applied for
soil aggregate monitoring, it will be necessary to analyse a reference material (RM) with consistent disaggregation
properties (DR value) to demonstrate that the procedure is consistent over the period of monitoring.
To our knowledge no one has previously attempted to use or apply a RM for testing soil aggregate stability.
We know of no commercially available anthropogenic material which has consistent disaggregation properties.
Field soils, which are exposed to seasonal variations in organic matter content plus wetting and drying cycles, are
unlikely to have sufficiently consistent disaggregation properties for use as an aggregate RM. Paleosols are likely
to be less reposnosive to seasoanl cycles because they are often buried at depths (>1 m) beyond the most active
hydrological and biogeochemical cycles, and so they are likely to disaggregate more consistently over time. They
are also sufficiently abundant for bulk samples to be collected repeatedly.We present analyses of DR for a paleosol
(brickearth) material collected from a site at Ospringe in Kent (sourthern England) at a depth of 1.6 m to determine
whether it has properties that indicate its potential for use as a RM for monitoring soil aggregate stability based on
the method presented by Rawlins et al.. We discuss the implications of our initial findings.
