The design and evaluation of non-visual information systems for blind users
(University of Hertfordshire, 1999)
This research was motivated by the sudden increase of hypermedia information (such as
that found on CD-ROMs and on the World Wide Web), which was not initially accessible
to blind people, although offered significant ...
A nuclear grand-design spiral within the normal disc spiral of NGC 5248
(1999-01)
We report the discovery of trailing grand-design nuclear spiral structure in the spiral galaxy NGC 5248. Two tightly-wound red spiral arms, with widths less than 1 arcsec (~ 75 pc), emanate at 1 arcsec outside the quiescent ...
Cunning-folk in the Medical Market-Place during the Nineteenth Century
(1999-01)
Over the last twenty years a considerable amount of valuable research has uncovered the activities of a variety of unorthodox medical practitioners in the eighteenth and nineteenth centuries. Quack doctors, spiritual ...
High-resolution UKIRT observations of circumnuclear star formation in M100
(1999-01)
We present high-resolution, near-infrared imaging of the circumnuclear region of the barred spiral galaxy M100 (=NGC 4321), accompanied by near-infrared spec- troscopy.We identify a total of 43 distinct regions in the ...
Effects of Pseudomonas fluorescens F113 on Ecological Functions in the Pea Rhizosphere Are Dependent on pH
(1999)
The aim of this microcosm study was to determine influence of the antibiotic 2,4 diacetylphloroglucinol (DAPG) on the effect of wild type and functionally modified Pseudomonas fluorescens F113 strains in a sandy loam soil ...
Temporal requirements and the human computer interface : not just an afterthought
(University of Hertfordshire, 1999)
Time plays an intrinsic part in the human computer interface. We argue that temporal issues must be recognised as fundamental to the interface, not relegated to the status of quality requirements. If we treat time as being ...
Model building with multiple dependent variables and constraints
(1999)
The most widely used method for finding relationships between several quantities is multiple regression. This however is restricted to a single dependent variable. We present a more general method which allows models to ...
Experiment One of the SAIC Remote Viewing Program: A Critical Re-evaluation - a reply to May
(1999)
In our original paper (Wiseman & Milton, 1999), we described a number of potential information leakage pathways in Experiment One of the SAIC remote viewing program. In this paper, we counter May’s assertion that the ...
Line-driven disc wind models with an improved line force
(1999)
We describe an efficient method of calculating the radiation pressure due to spectral lines, including all the terms in the velocity gradient tensor. We apply this method to calculate the two-dimensional, time-dependent ...
Estimation of Stellar Metal Abundance. II : A Recalibration of the Ca II K Technique, and the Autocorrelation Function Method
(1999)
We have recalibrated a method for the estimation of stellar metal abundance, parameterized as [Fe/H], based on medium-resolution (1–2 Å) optical spectra (the majority of which cover the wavelength range 3700–4500 Å). The ...
