Pak1 phosphorylation on T212 affects microtubules in cells undergoing mitosis
(2002-07-23)
The Pak kinases are targets of the Rho GTPases Rac and Cdc42, which regulate cell shape and motility [1-5]. It is increasingly apparent that part of this function is due to the effect Pak kinases have on microtubule ...
Tropospheric aerosol layers after a cold front passage in January 2000 as observed at several stations of the German Lidar Network
(2002-07)
Using the German Lidar Network, we analysed 2 years of lidar observations of aerosol layers. Here we report in particular on a cold front event in January 2000 with Rayleigh/Mie/Raman lidar measurements taken both in the ...
Massive star evolution : nucleosynthesis and nuclear reaction rate uncertainties
(2002-07)
We present a nucleosynthesis calculation of a 25 M-circle dot star of solar composition that includes all relevant isotopes up to polonium. We follow the stellar evolution from hydrogen burning till iron core collapse and ...
Characterisation of the dynamical quantum state of a zero temperature Bose–Einstein condensate
(2002-07-01)
We describe the quantum state of a Bose–Einstein condensate at zero temperature. By evaluating theQ-function we show that the ground state of Bose–Einstein condensate under the Hartree approximation is squeezed.We find ...
V-45(p,gamma) thermonuclear reaction rate relevant to Ti-44 production in core-collapse supernovae : General estimates and shell model analysis
(2002-07)
The lack of knowledge of the V-45(p,gamma) reaction rate has been shown to contribute a large uncertainty to the production of Ti-44 in core-collapse supernovae. By considering likely contributions from resonances associated ...
Chemodynamical evolution of galaxies
(2002-07)
I simulate the chemodynamical evolution of the Milky Way and elliptical galaxies using the GRAPE-SPH code. By reproducing the observations, I discuss the origin of elliptical galaxies
alpha- and neutron-induced reactions on ruthenium isotopes
(2002-07)
The uncertain origin of the proton rich Mo and Ru isotopes has motivated cross-section measurements of alpha- and neutron-induced reactions. The experiments were performed via the activation technique by irradiating thin ...
A probable planetary companion to HD 39091 from the Anglo-Australian Planet Search
(2002-07)
We report the detection of a extrasolar planet candidate orbiting the G1 V star HD 39091. The orbital period is 2083 d and the eccentricity is 0.62. With a minimum (M sin i) mass of 10.3 MJUP this object falls near the ...
Influence of foliar-applied calcium nitrate on strawberry plants grown under salt-stressed conditions
(2002-07)
A pot experiment was carried out with strawberry (Fragaria x ananassa Duch) cultivars Oso Grande and Camarosa in sand culture to investigate the effects of foliar-applied calcium nitrate [Ca(NO ) ] to plants grown at high ...
