Impact of wild-type and genetically modified Pseudomonas fluorescens on soil enzyme activities and microbial population structure in the rhizosphere of pea
(1998)
The aim of this work was to determine the impact of wild type along with functionally and non-functionally modified Pseudomonas fluorescens strains in the rhizosphere. The wild type F113 strain carried a gene encoding the ...
Subject specialists - primary schools
(1998)
This paper attempts to give an insight into the nature of subject specialism in primary schools; the way in which the concept has developed over time; the ways in which it is understood and interpreted by key players and ...
Dust Spirals and Acoustic Noise in the Nucleus of the Galaxy NGC 2207
(1998)
Observations with the Hubble Space Telescope reveal an irregular network of dust spiral arms in the nuclear region of the interacting disk galaxy NGC 2207. The spirals extend from »50 to »300 pc in galactocentric radius, ...
Spatial light scattering analysis as a means of characterising and classifying non-spherical particles
(1998)
The manner in which a particle scatters incident light is a function of the particle's shape, its size, its structure and its orientation with respect to the illumination direction, as well as to the wavelength and ...
Radiation-driven winds from luminous accretion discs
(1998)
We study the two-dimensional, time-dependent hydrodynamics of radiation-driven winds from luminous accretion disks in which the radiation force is mediated primar- ily by spectral lines. We assume the disk is flat, Keplerian, ...
Can animals detect when their owners are returning home? An experimental test of the 'psychic pet' phenomenon
(1998)
In his book, Seven Experiments That Could Change The World, Rupert Sheldrake suggested that the public carry out experiments to test whether pets can psychically detect when their owners are returning home. The first of ...
Developing the Hatfield Superscalar architecture cache simulator
(University of Hertfordshire, 1998)
A great deal of the current research into computer architecture is directed at Multiple Instruction Issue (MII) processors. These processors have the ability to issue, process and retire more than one instruction per cycle. ...
Establishment and impact of Pseudomonas fluorescens genetically modified for lactose utilization and kanamycin resistance in the rhizosphere of pea
(1998)
The impact of a Pseudomonas fluorescens strain, genetically modified for kanamycin resistance and lactose utilisation (the GMM), could be enhanced by soil amendment with lactose and kanamycin. Lactose addition decreased ...
Distinguishing Metabolic Heat from Condensation Heat during Muscle Recovery
(1998)
When a thermopile is used to measure the heat production of isolated muscle, the muscle is surrounded by gas saturated with water vapour, initially in equilibrium with the muscle. After contraction, the osmolarity of the ...
