PROPAGATION OF NUCLEAR DATA UNCERTAINTIES FOR PWR CORE ANALYSIS
Cabellos, O.,Castro, E.,Ahnert, C.,Holgado, C. Korean Nuclear Society 2014 Nuclear Engineering and Technology Vol.46 No.3
An uncertainty propagation methodology based on the Monte Carlo method is applied to PWR nuclear design analysis to assess the impact of nuclear data uncertainties. The importance of the nuclear data uncertainties for $^{235,238}U$, $^{239}Pu$, and the thermal scattering library for hydrogen in water is analyzed. This uncertainty analysis is compared with the design and acceptance criteria to assure the adequacy of bounding estimates in safety margins.

The assessment of the accuracy of parameters related to the reactor core performance (e.g. keff) and fuel cycle (e.g. isotopic evolution/transmutation) due to the uncertainties in the basic nuclear data (ND) is a critical issue. Different error propagation techniques (adjoint/forward sensitivity analysis procedures and/or Monte Carlo technique) can be used to address by computational simulation the systematic propagation of uncertainties on the final parameters. To perform this uncertainty assessment, the ENDF covariance files (variance/correlation in energy and cross-reactions-isotopes correlations) are required.In this paper, we assess the impact of ND uncertainties on the isotopic prediction for a conceptual design of a modular European Facility for Industrial Transmutation (EFIT) for a discharge burnup of 150 GWd/tHM. The complete set of uncertainty data for cross sections (EAF2007/UN, SCALE6.0/COVA-44G), radioactive decay and fission yield data (JEFF-3.1.1) are processed and used in ACAB code.

Finding largest rectangles in convex polygons
Cabello, S.,Cheong, O.,Knauer, C.,Schlipf, L. Elsevier 2016 Computational Geometry Vol.51 No.-
<P>We consider the following geometric optimization problem: find a maximum-area rectangle and a maximum-perimeter rectangle contained in a given convex polygon with n vertices. We give exact algorithms that solve these problems in time O(n(3)). We also give (1 - epsilon)-approximation algorithms that take time O(epsilon(-1/2) log n + epsilon(-3/2)). (C) 2015 Elsevier B.V.

Temporal and Physiological Characteristics of Elite Women`s and Men`s Singles Badminton
( David Cabello ),( Paulino Padial ),( Adrian Lees ),( Fernando Rivas ) 한국스포츠정책과학원(구 한국스포츠개발원) 2004 International Journal of Applied Sports Sciences Vol.16 No.2
Through a descriptive study of the temporal and physiological characteristics of elite singles badminton players, we were able to analyze a large sample of male and female Spanish players (n=79) who participated in national, international and world level competitions. We collected data on (a) temporal structure and actions in play, which were video-recorded and retrospectively analysed for all matches, (b) heart rates and (c) blood lactate concentration from capillary samples taken from the earlobe. These data were used to describe elite singles badminton competition in relation to sex and competition levels. Results showed that elite singles badminton is a highly demanding sport, with high maximum and mean heart rate (192 and 174 beats.min-1), a total match time over 30 minutes and an average rallies of 89 per match. Moreover, rallies had a rally length (work time) of 6.8 s and 13.9 s rest (rest time) between rallies. Significant differences existed between men`s and women`s modalities at all competition levels except for the World Championships, and between levels of elite competition. These findings have allowed recommendations to be made with regard to the preparation of players for competition at the highest level.
Essential oil impregnation into graphene sponges with electric desorption control
Mendez, Jose Antonio Cabello,Bueno, Jose de Jesus Perez,Valencia, Jorge Ivan Mendoza,Soto, Jonathan Soto,Lopez, Maria Luisa Mendoza,Guerrero, Mizraim Uriel Flores Techno-Press 2022 Advances in nano research Vol.12 No.6
This work shows the impregnation of scents using a graphene sponge (GS). This was functionalized by the modified Hummers method, pursuing to add different functional groups. It is proposed to achieve the release and seek to control it through electrical potential applied to the graphene sponge with essential oils. The graphene sponge was functionalized and steeped with two kinds of oil. The electrochemical study demonstrates the variation in the electrochemical behaviour of the functionalized graphene sponge without and impregnated with oil. The release of the oil and its aromatic scents was carried out by applying an electrical potential of 30 V, with a release rate of 1.86 mg/min. The heating of the sample that causes the release of oil, associated with the electrical resistance of the system, reaches temperatures of about 150℃. The essential oils, graphene sponge, surfactant, graphene sponge with essential oils, graphene sponge recuperated after applying electric potential, graphene sponge recovered by temperature and dipropylene glycol (DPG) were characterized using Fourier transformed infrared spectroscopy (FTIR), digital microscopy, and x-ray photoelectron spectroscopy (XPS).
Design and Validation of a Computer Application for Diagnosis of Shoulder Locomotor System Pathology
Albert Bigorda-Sague,Javier Trujillano Cabello,Gemma Ariza Carrio,Carmen Campoy Guerrero 대한의료정보학회 2019 Healthcare Informatics Research Vol.25 No.2
Methods: The first phase involved the construction of the application using the Delphi method. In the second phase, the application was validated with a sample of 250 patients with shoulder pathology. Validity was measured for each diagnostic group using sensitivity, specificity, and positive and negative likelihood ratio (LR(+) and LR(–)). The correct classification ratio (CCR) for each patient and the factors related to worse classification were calculated using multivariate binary logistic regression (odds ratio, 95% confidence interval). Results: The mean time to complete the application was 15 ± 7 minutes. The validity values were the following: LR(+) 7.8 and LR(–) 0.1 for cervical radiculopathy, LR(+) 4.1 and LR(–) 0.4 for glenohumeral arthrosis, LR(+) 15.5 and LR(–) 0.2 for glenohumeral instability, LR(+) 17.2 and LR(–) 0.2 for massive rotator cuff tear, LR(+) 6.2 and LR(–) 0.2 for capsular syndrome, LR(+) 4.0 and LR(–) 0.3 for subacromial impingement/rotator cuff tendinopathy, and LR(+) 2.5 and LR(–) 0.6 for acromioclavicular arthropathy. A total of 70% of the patients had a CCR greater than 85%. Factors that negatively affected accuracy were massive rotator cuff tear, acromioclavicular arthropathy, age over 55 years, and high pain intensity (p < 0.05). Conclusions: The developed application achieved an acceptable validity for most pathologies. Because the tool had a limited capacity to identify the full clinical picture in the same patient, improvements and new studies applied to other groups of patients are required.

Chylomicron retention disease, also known as Anderson’s disease, is a rare hereditary hypocholesterolemic dis-order, recessive inherited, characterized by nonspecific symptoms as abdominal distension, steatorrhea, and vomit-ing associated with failure to thrive. We describe a patient with failure to thrive, chronic diarrhea and steatorrhea who the diagnosis of chylomicron retention disease was established after several months of disease progression. The genetic study confirmed a homozygosity mutation in SAR1B gene, identifying a mutation never previous de-scribed [c.83_84delTG(p.Leu28Argfs*7)]. With this case report the authors aim to highlight for this very rare cause of failure to thrive and for the importance of an attempting diagnosis, in order to start adequate management with low fat diet supplemented with fat-soluble vitamins, reverting the state of malnutrition and avoiding possible irrever-sible and desvantating complications.

The aim of this work was to determine the behavior of alloy elements and compounds formed during solidification in the manufacturing process of the CuAgZrCr alloy under an oxidizing environment. Bulk and surface analysis techniques, such as Scanning Electron Microscopy (SEM), X-ray Photoelectron Spectroscopy (XPS), Raman and X-ray diffraction (XRD) were used to characterize the phases obtained in the solidification process. In order to focus the analysis on the on grain boundary interface, partial removal of the matrix phase by acid attack was performed. The compositional differences obtained by SEM-EDX, Raman and XPS on post-manufacturing materials allowed us to conclude that the composition of grain boundaries of the alloy is directly influenced by the oxidizing environment of alloy manufacturing.
