Comportamiento experimental de conexiones soldadas entre tubos cuadrados de acero conformados por perfiles G de 60x30x10x2 y 80x40x15x3 mm sometidas a carga monotónica.

Publication Type: Academic Journal

Source(s): Revista Tecnica de la Facultad de Ingenieria de la Universidad del Zulia. may-ago2021, Vol. 44 Issue 2, p92-103. 12p.

Abstract: En el Ecuador se ha incrementado el uso de conexiones con tubulares cuadrados de acero en viviendas y centros comerciales. Sin embargo, no existe una normativa que explique su comportamiento. En esta investigación se evaluó el comportamiento experiment...

Ultrasound Imaging of the Periodontium Complex: A Reliability Study.

Publication Type: Academic Journal

Source(s): International Journal of Dentistry. 2/16/2023, p1-10. 10p.

Abstract: Background. Ultrasonography is a noninvasive, low-cost diagnostic tool widely used in medicine. Recent studies have demonstrated that ultrasound imaging might have the potential to be used intraorally to assess periodontal biomarkers. Objectives. To ev...

Fast Fault Identification in Bipolar HVDC Grids: A Fault Parameter Estimation Approach.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Power Delivery. Feb2022, Vol. 37 Issue 1, p258-267. 10p.

Abstract: The protection of meshed HVDC grids requires the fast identification of faults affecting the transmission lines. Communication-based methods are thus not suited due to the transmission delays. Many approaches involving a model of the transient behavior...

Diseño y validación de un instrumento de evaluación del clima organizacional en centros escolares del nivel superior

Publication Type: Academic Journal

Source(s): Revista Iberoamericana de Educación, Vol 67, Pp 181-196 (2015)

Abstract: El presente artículo muestra el proceso de diseño y validación de un instrumento de evaluación del clima organizacional, creado desde la teoría clásica y las improntas de los centros educativos del nivel superior. La metodología utilizada se estructuró...

Unraveling Amazon tree community assembly using Maximum Information Entropy: a quantitative analysis of tropical forest ecology

Publication Type: Academic Journal

Source(s): Scientific Reports, Vol 13, Iss 1, Pp 1-11 (2023)

Abstract: Abstract In a time of rapid global change, the question of what determines patterns in species abundance distribution remains a priority for understanding the complex dynamics of ecosystems. The constrained maximization of information entropy provides ...


Magnitude estimation and ground motion prediction to harness fiber optic distributed acoustic sensing for earthquake early warning

Publication Type: Academic Journal

Source(s): Scientific Reports, Vol 13, Iss 1, Pp 1-14 (2023)

Abstract: Abstract Earthquake early warning (EEW) systems provide seconds to tens of seconds of warning time before potentially-damaging ground motions are felt. For optimal warning times, seismic sensors should be installed as close as possible to expected eart...


Colorectal cancer incidences in Lynch syndrome: a comparison of results from the prospective lynch syndrome database and the international mismatch repair consortium

Publication Type: Academic Journal

Source(s): Hereditary Cancer in Clinical Practice, Vol 20, Iss 1, Pp 1-11 (2022)

Abstract: Abstract Objective To compare colorectal cancer (CRC) incidences in carriers of pathogenic variants of the MMR genes in the PLSD and IMRC cohorts, of which only the former included mandatory colonoscopy surveillance for all participants. Methods CRC in...

Long-term kidney function recovery and mortality after COVID-19-associated acute kidney injury: An international multi-centre observational cohort studyResearch in context

Publication Type: Academic Journal

Source(s): EClinicalMedicine, Vol 55, Iss , Pp 101724- (2023)

Abstract: Summary: Background: While acute kidney injury (AKI) is a common complication in COVID-19, data on post-AKI kidney function recovery and the clinical factors associated with poor kidney function recovery is lacking. Methods: A retrospective multi-centr...

Targeting the overexpressed mitochondrial protein VDAC1 in a mouse model of Alzheimer’s disease protects against mitochondrial dysfunction and mitigates brain pathology

Publication Type: Academic Journal

Source(s): Translational Neurodegeneration, Vol 11, Iss 1, Pp 1-30 (2022)

Abstract: Abstract Background Alzheimer's disease (AD) exhibits mitochondrial dysfunctions associated with dysregulated metabolism, brain inflammation, synaptic loss, and neuronal cell death. As a key protein serving as the mitochondrial gatekeeper, the voltage-...

Mass testing and characterization of 20-inch PMTs for JUNO

Publication Type: Academic Journal

Source(s): European Physical Journal C: Particles and Fields, Vol 82, Iss 12, Pp 1-42 (2022)

Abstract: Abstract Main goal of the JUNO experiment is to determine the neutrino mass ordering using a 20 kt liquid-scintillator detector. Its key feature is an excellent energy resolution of at least 3% at 1 MeV, for which its instruments need to meet a certain...
