Thermal properties of vortices on curved surfaces
(American Physical Society, 2018-01-16)
We use Monte Carlo simulations to study the finite temperature behavior of vortices in the XY model for tangent vector order on curved backgrounds. Contrary to naive expectations, we show that the underlying geometry does ...
A simplified spectrophotometric method for routine analysis of saccharin in commercial noncaloric sweeteners
(2004-12-29)
A simple, rapid, and sensitive spectrophotometric method for routine analysis of saccharin in commercial noncaloric sweeteners is proposed. This method is based on the reaction of saccharin with tetrachloro-p-benzoquinone ...

Type II supernova spectral diversity, II: spectroscopic and photometric correlations
(IOP Publishing, 2017-11)
We present an analysis of observed trends and correlations between a large range of spectral and photometric parameters of more than 100 type II supernovae (SNe II), during the photospheric phase. We define a common epoch ...
Rapid and sensitive method for the determination of acetaldehyde in fuel ethanol by high-performance liquid chromatography with UV-Vis detection
(Springer, 2005-04-01)
A high-performance liquid chromatography (HPLC) method for the determination of acetaldehyde in fuel ethanol was developed. Acetaldehyde was derivatized with 0.900 mL 2,4-dinitrophenylhydrazine (DNPHi) reagent and 50 mu L ...
Rapid and sensitive method for detecting adulterants in gasoline using ultra-fast gas chromatography and Partial Least Square Discriminant Analysis
(2018-03-01)
In the last years, the Brazilian Fuel Quality Monitoring Program drastically reduced the number of analyzed fuel samples as consequence of the current economic crisis in the country. The impoverishment of the monitoring ...
Type II supernova spectral diversity. II. Spectroscopic and photometric correlations
(IOP Publishing Ltd., 2017)
We present an analysis of observed trends and correlations between a large range of spectral and photometric parameters of more than 100 type II supernovae (SNe II), during the photospheric phase. We define a common epoch ...
Diphoton ridge in p plus p and p plus A collisions at RHIC and the LHC
(2015)
We obtain prompt diphoton cross section in proton-nucleus collisions in Hamiltonian light-cone approach within a hybrid approximation, treating the projectile proton in the parton model and the target nucleus in the ...
STARCH OF DIVERSE MEXICAN RICE CULTIVARS: PHYSICOCHEMICAL, STRUCTURAL, AND NUTRITIONAL FEATURES.
(2013-02-19)
Structure-function relationship of rice starch is scarce in the literature. Starch was isolated from diverse Mexican rice varieties and their swelling power (SP), soluble solids (ss), thermal and pasting properties, XRD ...
Evaluation of the LFA-REAL clinician-reported outcome (ClinRO) and patient-reported outcome (PRO): data from the Peruvian Almenara Lupus Cohort
(BMJ Publishing Group, 2020)
Objective: The Lupus Foundation of America Rapid Evaluation of Activity in Lupus (LFA-REAL) clinician-reported outcome (ClinRO) and the LFA-REAL patient-reported outcome (PRO) were developed in order to capture manifestations ...
