A compact high-resolution spectrometer based on a segmented conical crystal analyzer
(American Institute of Physics, 2020-04)
In this work, the design, fabrication, and evaluation of a compact, one-shot spectrometer based on a segmented conically bent crystal analyzer are described. The system is a “one-shot” wavelength dispersive spectrometer, ...
The environs of the massive runaway star BD+43 3654
(Universidad Nacional Autónoma de México. Instituto de Astronomía, 2010-02)
The very massive runaway star BD+43° 3654 (O4 If) seems to be related with a bow shock detected by the MSX mission, that would be the result of the interaction of the strong stellar wind with the ambient matter. Shock-accelerated ...
The origin of matter at the base of relativistic jets in active galactic nuclei
(Multidisciplinary Digital Publishing Institute, 2020-07-18)
The generation of relativistic jets in active sources such as blazars is a complex problem with many aspects, most of them still not fully understood. Relativistic jets are likely produced by the accretion of matter and ...
Non-thermal emission from the interaction of extragalactic jets with stars
(AIP Publishing, 2017)
The central regions of galaxies are rich environments, with abundant stars and medium inhomogeneities. For galaxies hostingactive galactic nuclei, the interaction of a relativistic jet with obstacles can lead to the formation ...
Characterization of fossil remains using XRF, XPS and XAFS spectroscopies
(IOP Publishing, 2016-08)
Synchrotron radiation micro-X-Ray Fluorescence (m-XRF), X-ray photoelectron (XPS) and X-ray Absorption Fine Structure (XAFS) spectroscopies are applied for the study of paleontological findings. More specifically the costal ...
Rotatable anisotropy of epitaxial Fe1-xGax thin films
(Edp Sciences, 2013-04-24)
We show by a combined magnetic force microscopy and synchrotron radiation spectroscopy study that stripe-like patterned magnetic domains are present in Fe1−x Gax thin films. These stripes, whose origin is attributed to an ...
Purification and preliminary crystallographic analysis of a new Lys49-PLA2 from B-jararacussu
(Mdpi Ag, 2008-05-01)
BjVIII is a new myotoxic Lys49-PLA2 isolated from Bothrops jararacussu venom that exhibits atypical effects on human platelet aggregation. To better understand the mode of action of BjVIII, crystallographic studies were ...
Purification, partial characterization and preliminary X-ray diffraction analysis of a mannose-specific lectin from Cymbosema roseum seeds
(Blackwell Publishing, 2006-03-01)
A lectin from Cymbosema roseum seeds (CRL) was purified, characterized and crystallized. The best crystals grew in a month and were obtained by the vapour-diffusion method using a precipitant solution consisting of 0.1 M ...
Crystallization and preliminary X-ray diffraction analysis of prephenate dehydratase from Mycobacterium tuberculosis H37Rv
(Blackwell Publishing, 2006-04-01)
Tuberculosis remains the leading cause of mortality arising from a bacterial pathogen ( Mycobacterium tuberculosis). There is an urgent need for the development of new antimycobacterial agents. The aromatic amino-acid ...
Selenium fractionation from plasma, muscle and liver of Nile tilapia (Oreochromis niloticus)
(2013-09-02)
This paper presents the results obtained from selenium fractionation in plasma, muscle and liver samples of Nile tilapia's (Oreochromis niloticus) after protein separation. The plasma, muscle and liver proteome was obtained ...
