Behavior of basalt under laser-induced shock-wave application to the planetary hypervelocity impact effect [PDF]

open access: yes, 2011
This paper presents the results of an investigation of the impact of laser-induced shock on basalt samples in a water confinement regime. In order to observe the effect of laser shock-wave propagation, in this material, the rear free surface velocity is ...

A política de dividendos como geradora de economia fiscal e do desenvolvimento do mercado de capitais: uma proposta criativa

open access: yesRAE: Revista de Administração de Empresas, 1993
A fome fiscal do governo brasileiro tem sido reclamada constantemente pelo empresariado local. Apesar disso, e sabendo que a taxação dos dividendos não existe, ao mesmo tempo em que a sobre ganhos de capital foi instituída, podemos verificar que através ...

Magnetized fast isochoric laser heating for efficient creation of ultra-high-energy-density states

open access: yesNature Communications, 2018
It is desirable to deposit more energy in the dense plasma core to trigger the fusion ignition. Here the authors demonstrate enhanced energy coupling from laser to plasma core by using solid targets and guiding the transport of relativistic electron beam

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Energy redistribution during CO2 laser cladding

open access: yes, 2002
This article examines the factors that effect the efficiency of the CO sub 2 -laser powder cladding process. By theoretical calculation and experimental work it has been possible to identify how much of the original laser energy contributes to the ...
