A superconducting undulator is installed in the ANKA (ANgstrom source KArlsruhe) storage ring since March 2005. The beam heat load and pressure on the cold bore have been analysed in the first two years of operation, during which the undulator was operated mainly with open gap. We report here on a larger statistics of beam heat load and pressure data collected in the last years with the undulat...

greece has experienced particularly severe and frequent forest fires during summer 2007 together with exceptionally dry meteorological conditions culminated in distinct heat waves. the present study analyzes the time pattern of daily values of two fire risk indices (nesterov and angstrom) based on meteorological data made available for a number of gauging stations between 1 june and 31 august o...

With current advances in sub-angstrom resolution scanning transmission electron microscopy (STEM), it is now possible to image directly local crystal structures of materials where dramatically different atoms are separated from each other at distances about or less than 1 angstrom. We achieved direct imaging of atomic columns of nitrogen in close proximity to columns of aluminum in wurtzite alu...

We present an optical transmission spectrum for WASP-94A b, the first atmospheric characterisation of this highly-inflated hot Jupiter. The planet has a reported radius $1.72^{+0.06}_{-0.05}$ R$_{\textrm{Jup}}$, mass only $0.456^{+0.032}_{-0.036}$ M$_{\textrm{Jup}}$, and equilibrium temperature $1508 \pm 75$ K. observed transit spectroscopically with EFOSC2 instrument on ESO New Technology Tele...

Density Function Theory (DFT) calculation was used to find out ground and excitation states for graphene ribbons, types of adsorption, energy gap, maximum wave length optical band gap. Adsorption showed that CO2 gas molecule had chemical adsorption in distance 1 1.5 Angstrom. appeared have physical 2 2.5 decreased when the between surface increased. Resulting from there a change Angstrom due at...

Nucleoside diphosphate kinases (NDKs; EC 2.7.4.6) play an essential role in the synthesis of nucleotides from intermediates in the salvage pathway in all parasitic trypanosomatids and their structural studies will be instrumental in shedding light on the biochemical machinery involved in the parasite life cycle and host-parasite interactions. In this work, NDKb from Leishmania major was overexp...

In this paper, imperialist competitive algorithm as a computational method is implemented in MATLAB software to estimate monthly average daily global solar radiation on horizontal surface for some different climate cities of Iran. The experimental coefficients for Angstrom model have been calculated using imperialist competitive algorithm for all different climate cities and output data compare...

suspended aerosols in the atmosphere have strong impact on the global climate. they influence the earth’s radiation budget by scattering or absorbing both incoming and outgoing radiation. aerosols in troposphere are caused by natural sources, such as dust, sea-spray and volcanoes and also by anthropogenic sources, such as combustion of fossil fuels and biomass burning activities and from gas-to...
