Antiproliferative and structure activity relationships of amaryllidaceae alkaloids
(MDPI, 2015-07-30)The antiproliferative activity of a set of seven natural Amaryllidaceae alkaloids and 32 derivatives against four cancer cell lines (A2780, SW1573, T47-D and WiDr) was determined. The best antiproliferative activities were ... -
A computational methodology to calculate the required power in disc crushers
(Oxford University Press, 2016-09-15)This study aims to contribute to the estimation of power consumption in a disintegration process in disc crushers (fixed and mobile). The study covers the dynamic analysis of forces acting on the particles and the mobile ... -
Despeckle filtering for multiscale amplitude-modulation frequency-modulation (AM-FM) texture analysis of ultrasound images of the intima-media complex
(Hindawi Publishing Corporation, 2014-03-09)The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of cardiovascular disease (CVD). Typically, the IMT grows with age and this is used as a sign of increased risk of ... -
Extreme salinity as a challenge to grow potatoes under Mars-like soil conditions: targeting promising genotypes
(Cambridge University Press, 2017-11-16)One of the future challenges to produce food in a Mars environment will be the optimization of resources through the potential use of the Martian substratum for growing crops as a part of bioregenerative food systems. In ... -
Managing warehouse efficiency and worker discomfort through enhanced storage assignment decisions
(Taylor and Francis Group, 2016-04-06)Humans are at the heart of crucial processes in warehouses. Besides the common economic goal of minimising cycle times, we therefore add in this paper the human well-being goal of minimising workers’ discomfort in the ... -
Boundary discontinuous Fourier analysis of thick beams with clamped and simply supported edges via CUF
(Chinese Journal of Aeronautics, 2017-07-11)This paper presents an analytical solution for static analysis of thick rectangular beams with different boundary conditions. Carrera's Unified Formulation (CUF) is used in order to consider shear deformation theories of ... -
A boundary-discontinuous-displacement based Fourier analysis of thick laminated beams via a robust 1D-CUF model
(Elsevier, 2017-04-17)This paper presents an analytical solution for the static analysis of thick laminated rectangular beams with clamped boundary conditions at either or both of the beam's edges. A unified formulation known as Carrera's Unified ... -
Bedforms-ATM, an open source software to analyze the scale-based hierarchies and dimensionality of natural bed forms
(Elsevier, 2018-06-30)Bedforms-ATM (Bed forms analysis toolkit for multiscale modeling) is a software designed to hierarchize and quantify the dimensionality of natural bed forms fields. It comprises four modular applications, namely: (1) wavelet ... -
Respuestas a comentarios "Superando Las Dicotomías: El Qhapaq ñan Como ejemplo del patrimonio como proceso social"
(Universidad de Tarapacá, 2019-09-24)Antes de comenzar quisiera agradecer a los colegas que aceptaron hacer comentarios a mi artículo “Superando las dicotomías: el Qhapaq Ñan como ejemplo del patrimonio como proceso social”. En especial porque no es una tarea ... -
Assessment of diastolic function and atrial remodeling by MRI – validation and correlation with echocardiography and filling pressure
(WileyAmerican Physiological Society, 2018-09-05)Atrial fibrosis can be estimated noninvasively by magnetic resonance imaging (MRI) using late gadolinium enhancement (LGE), but diastolic dysfunction is clinically assessed by transthoracic echocardiography (TTE), and ... -
Identification of surface processes in individual minerals of a complex ore through the analysis of polished sections using polarization microscopy and x-ray photoelectron spectroscopy (Xps)
(MDPI, 2018-09-28)Understanding the changes of a mineral during ore processing is of capital importance for the development of strategies aimed at increasing the efficiency of metal extraction. This task is often difficult due to the ... -
