Introducción: Los cultivos de café, cacao y pasturas para la ganadería son actividades agropecuarias interés económico en Colombia. Cuando estas se desarrollan bajo sistemas agroforestales (SAF) promueven conservación e incrementan fijación carbono y, por ende, mitigación del cambio climático. Objetivo: El estudio estimó el almacenamiento biomasa aérea, necromasa orgánico suelo SAF con (SAF cac...

[1] The San Andreas Fault (SAF) is the transform boundary between the Pacific and the North American plates, yet up to 25% of the relative plate motion is now accommodated by the eastern California shear zone (ECSZ). Here we investigate the inception of the ECSZ and its geodynamic interactions with the SAF using a 3‐D viscoelastoplastic finite element model. For a given fault configuration of t...

The Amphoteric Fatliquor (AF) was prepared by rapeseed oil, 1, 2-ethylenediamine and acrylic acid. An amphoteric fatliquor (SAF) modified with silicon was synthesized by using AF and polyether silicon with stirring and ultrasonic treatment. AF and SAF were measured by Fourier Transform Infrared Spectroscopy (FT-IR), thermogravimetry (TGA), emulsifying capacity, emulsification stability and emul...

Higher eukaryotic chromosomes are organized into topologically constrained functional domains; however, the molecular mechanisms required to sustain these complex interphase chromatin structures are unknown. A stable matrix underpinning nuclear organization was hypothesized, but the idea was abandoned as more dynamic models of chromatin behavior became prevalent. Here, we report that scaffold a...

We describe an approach that utilizes nonlinear peptides to direct the assembly of previously reported Self-Assembling Fibers (SAFs). The SAF system comprises two complementary linear peptides, SAF-p1 and SAF-p2a, which combine to form exclusively linear, nonbranched fibers. The Matrix-Programming (MaP) peptides described herein are based on these peptides: they comprise two or three half-pepti...

Three earthquake clusters that occurred in the direct vicinity of the southern terminus of the San Andreas Fault (SAF) in 2001, 2009, and 2016 raised significant concern regarding possible triggering of a major earthquake on the southern SAF, which has not ruptured in more than 320 years. These clusters of small and moderate earthquakes withM ≤ 4.8 added to an increase in seismicity rate in the...

The San Andreas Fault (SAF) is the Pacific-North American plate boundary, yet in southern California a significant portion of the relative plate motion is accommodated by the San Jacinto Fault (SJF). Here we investigate the initiation of the SJF and its interaction with the SAF in a threedimensional visco-elasto-plastic finite-element model. The model results show that the restraining bend of t...

Background: Air fresheners are products with fragrances used to mask unpleasant odor in the environment. However, air fresheners contain diverse chemical substances that pose health challenges to the users; hence are of public health significance. Although previous studies have shown that air fresheners affect the lungs, liver and reproductive organs, the neurobehavioral effects of these agent...

479 and XIIIa. Low-grade myxofibrosarcoma is positive for vimentin, but it is negative for CD34 and desmin. Myxoid neurofibroma is a tumor of neural origin, showing positive immunohistochemistry for S100, which is of help in making a differential diagnosis of SAF [1-5]. It is known that SAF has a benign natural course, for which the standard treatment modality is complete surgical removal. Inco...
