A marine biogenic source of atmospheric ice-nucleating particles
The amount of ice present in clouds can affect cloud lifetime, precipitation and radiative properties. The formation of ice in clouds is facilitated by the presence of airborne ice-nucleatingExpand

Scottish Rock Ptarmigan (Lagopus mutus) showed unstable population dynamics, with density-dependent features differing between areas on rich and poor soils. The study was conducted on arctic–alpineExpand

Mass loss in incubating Eurasian dotterel: adaptation or constraint?
Body mass loss is frequently observed in breeding birds: whether this is an adaptive response to a change in the relative value of body stores and locomotion performance or a consequence of energeticExpand

  • 1 March 1993
Abstract Two-dimensional simulation results are presented for the case of an intense ultrashort laser pulse propagating through an initially neutral high-pressure gas. The combined effects ofExpand

Short-pulse laser-plasma interactions
 This thesis deals with several theoretical aspects of the interaction of an intense femtosecond laser pulse with a plasma. A mechanism for the enhancement of the collisional absorption of light atExpand

Numbers and distribution of Dotterel Charadrius morinellus breeding in Great Britain
The Dotterel, one of Britain's rarer breeding birds, nests on montane plateaux. Numbers and distribution of breeding Dotterel in Britain were determined by an extensive survey in 1987 and 1988Expand

Comparisons between nesting densities of Tawny Frogmouths (Podargus strigoides) in open- and closed-canopy woodlands
Abstract The Tawny Frogmouth (Podargus strigoides) is a common and familiar bird, yet there is little known of their densities in different woodland habitats. Nests of Tawny Frogmouths were surveyedExpand

Spectral blue shifting of a femtosecond laser pulse propagating through a high-pressure gas
Plasma-induced spectral blue shifting in rare gases has been investigated with a subpicosecond KrF excimer laser focused to a peak intensity in the region of 1014 W/cm2 (adiabaticity parameter in theExpand

Spectral blueshifting and spatial defocusing of intense laser pulses in dense gases
Abstract When an intense ultrashort laser pulse is focused into a dense gas, a plasma can be generated directly by multiphoton or tunneling ionisation. This plasma can affect the propagation of theExpand

Modelling of weather radar echoes from anomalous propagation using a hybrid parabolic equation method and NWP model data
We demonstrate a fast hybrid PEM technique that is capable of providing acceptable results in conjunc- tion with a high-resolution terrain elevation model, using a standard desktop personal computer. Expand
