1H NMR Spectroscopy and MR Imaging with hyperpolarised substances
(Elsevier, 2014)Despite their wide applicability in natural sciences, NMR and MRI still suffer from their inherently low sensitivity. This can be overcome by hyperpolarisation techniques, such as parahydrogen-induced polarisation and ... -
3D hydrodynamic modelling to optimize the hydraulic efficiency of the weirs and turbines intakes of the Néstor Kirchner dam in Santa Cruz, Argentina
(2015)In this work 3D hydrodynamic modeling were performed on the weir channel access and the turbines intakes of Nestor Kirchner dam in the province of Santa Cruz (Argentina). Different alternatives of the layout scheme of ... -
A 1.6Gb/s CMOS LVDS Transmitter with a Programmable Pre-Emphasis System
(2014)A 12 parallel low voltage differential signaling (LVDS) transmitter fabricated in 0.13 μm CMOS is presented. Each LVDS channel can operate over 1.6 Gb/s and includes a programmable pre-emphasis circuit designed to ... -
A 6-bit 2GS/s CMOS Time-Interleaved ADC for Analysis of Mixed-Signal Calibration Techniques
(2014)A 6-bit 2-GS/s time interleaved (TI) successive approximation register (SAR) analog-to-digital converter (ADC) is designed and fabricated in a 0.13 μm CMOS process. The architecture uses 8 time-interleaved track-and-hold ... -
A comparative study of the behaviour/stress distribution (tensional forces) around short and standard length implants on the posterior area to the maxilla. Finite element analysis
(2014)Current studies conclude that the maximum tension and the greater distribution of forces would occur around the implant neck endorsing the use of short implants. Objectives: Compare the distribution of tensions between a ... -
A Longitudinal Study on the Changes in Mental Health of Healthcare Workers during the COVID-19 Pandemic
(2021-07-30)Objective: This study examines Argentinean health care workers in order to 1) test self-perceived job performance levels and the presence of psychological symptoms compatible with common mental disorders, and 2) examine ... -
A longitudinal study on the changes in mental health of healthcare workers during the COVID-19 pandemic
(2021-02-01)We based this study on Argentinean healthcare workers in order to 1) test self-perceived job performance levels and the presence of psychological symptoms compatible with common mental disorders, and 2) examine within-person ... -
A model about the interaction of the monetary policy in an advanced and an emerging economy
(2014-11)A Dynamic Stochastic General Equilibrium model is developed for two open economies (advanced and emerging). A critical distinction between the economies rests on the location of financial frictions: imperfections affect ... -
A multimodal corpus of rapid dialogue games
(2014)This paper presents a multimodal corpus of spoken human-human dialogues collected as participants played a series of Rapid DialogueGames (RDGs). The corpus consists of a collection of about 11 hours of spoken audio, video, ... -
A multipurpose experimental facility for advanced X-ray Spectrometry applications
(2014)Motivation, Ultra High Vacuum Chamber (UHVC) project: To support/enhance the training of scientists/engineers from developing countries in the operation of synchrotron radiation instrumentation; To provide beam time access ... -
A multiscale model of virus pandemic: Heterogeneous interactive entities in a globally connected world
(World Scientific, 2020-06)This paper is devoted to the multidisciplinary modelling of a pandemic initiated by an aggressive virus, specifically the so-called SARS–CoV–2 Severe Acute Respiratory Syndrome, corona virus n.2. The study is developed ... -
A necessary change from 'man' to 'hommo sapiens' : an ecocritical study of Oryx and crake and The year of the flood by Margaret Atwood
(2015)It is undeniable that the deteriorating situation of the ecosystem is one of the hottest issues in our world today and indeed one worth contemplating in literary productions. Questions like the destruction of the forests, ... -
A needs analysis case regarding the use of English of Farming Engineering Students of the School of Agronomic Sciences of the National University of Córdoba, Argentina
(2018)This study presents a needs analysis (NA) carried out at the School of Farming Engineering (FCA) of the National University of Córdoba (UNC) to identify the present and future needs of the students of the FCA in terms ... -
A new approach to image segmentation with two-dimensional hidden Markov models
(2013)Image segmentation is one of the fundamental problems in computer vision. In this work, we present a new segmentation algorithm that is based on the theory of twodimensional hidden Markov models (2D-HMM). Unlike most ... -
A new approach to segmentation of remote sensing images with hidden markov models
(2014)In this work, we present a new segmentation algorithm for remote sensing images based on two-dimensional Hidden Markov Models (2D-HMM). In contrast to most 2D-HMM approaches, we do not use Viterbi Training, instead we ... -
A novel CLN8 missense mutation underlies variant late infantile neuronal ceroid lipofuscinosis in Latin America
(2013)Neuronal ceroid lipofuscinosis (NCL), inheritedneurodegenerative diseases of all ages, presents with storage oflipofuscin-like lipopigments in cerebral neurons and peripheraltissues. Mutations in CLN8 gene causing epilepsy ... -
