Importance of considering helium excited states in He + scattering by an aluminum surface
(American Physical Society, 2014-11)
The He+/Al system is a very interesting projectile-surface combination which was thought initially as an example of a pure Auger neutralization mechanism. Then, because of the measured reionization explained by the antibonding ...
Stopping power and depth dose profile of H+ and He+ ion beams in hydroxyapatite thin films.
(Gdańsk University of TechnologySopot, 2013-05-20)
Hadron therapy is a promising technique to treat deep-seated tumors. For an accurate treatment planning, the energy deposition in the soft and hard human tissue must be well known. Water has been usually employed as a ...
Floral regulators FLC and SOC1 directly regulate expression of the B3-type transcription factor TARGET OF FLC AND SVP 1 at the Arabidopsis shoot apex via antagonistic chromatin modifications
(Public Library of Science, 2019-04)
Integration of environmental and endogenous cues at plant shoot meristems determines the timing of flowering and reproductive development. The MADS box transcription factor FLOWERING LOCUS C (FLC) of Arabidopsis thaliana ...
Estudo de caso sobre exposição a violência intrafamiliar de uma criança PAEE
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosEducação Especial - EEspL, 2017-12-06)
The present work describes a case study with the objective of investigating the impact of intrafamily violence on the academic performance of children in the target group of special education considering the conditions of ...
Nanostructured europium oxide thin films deposited by pulsed laser ablation of a metallic target in a He buffer atmosphere
(A V S AMER INST PHYSICS, 2010)
Nanostrucured europium oxide and hydroxide films were obtained by pulsed Nd:YAG (532 nm) laser ablation of a europium metallic target, in the presence of a 1 mbar helium buffer atmosphere. Both the produced film and the ...
Mitochondria, endoplasmic reticulum and actin filament behavior after PDT with chloroaluminum phthalocyanine liposomal in HeLa cells
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2008)
Photodynamic therapy (PDT) for cancer is a therapeutic modality in the treatment of tumors in which visible light is used to activate a photosensitizer. Cell membranes have been identified as an important intracellular ...
A semi-nested RT-PCR assay targeted to hemagglutinin-esterase gene of Bovine Coronavirus
(São Paulo, 2010)
Bovine coronavirus (BCoV) is a non-segmented positive-sense single-stranded RNA virus whose envelope is constituted by a lipid bilayer with four structural proteins (HE, S, E and M) giving its characteristic crown-like ...
Ps-He scattering using the three-state positronium close-coupling approximation
(Iop Publishing Ltd, 1999-04-14)
A three-state target elastic positronium close-coupling approximation (CCA) is employed to investigate Ps-He scattering in the energy range 0-200 eV with and without electron exchange. Low-lying phase shifts below the first ...

Helium Line Formation and Abundance in a Solar Active Region
(IOP Publishing, 2005-12)
An observing campaign (SOHO JOP 139), coordinated between ground-based and Solar and Heliospheric Observatory (SOHO) instruments, has been planned to obtain simultaneous spectroheliograms of the same active region in several ...
