Stroke is a major cause of death and disability, with most of its burden now affecting low- and middle-income countries (LMIC). People in rural areas of LMIC who have a stroke receive very little acute stroke care and local healthcare workers and family caregivers in these regions lack the necessary knowledge to assist them. Intriguingly, a recent rapid growth in cell-phone use and digital technology in rural areas has not yet been appropriately exploited for health care training and delivery purposes. What should be done in rural areas, at the community setting-level, where access to healthcare is limited remains a challenge. We review the evidence on improving post-stroke outcomes including lowering the risks of functional disability, stroke recurrence, and mortality, and propose some approaches, to target post-stroke care and rehabilitation, noting key challenges in designing suitable...

Background: Self-injurious behaviors are highly prevalent in individuals with autism spectrum disorder (ASD), occurring frequently in those with associated intellectual disabilities as well as in those without intellectual impairment. Single-case studies have found that functional communication training helps regulate self-injurious behaviors and repetitive behaviors, particularly in children with ASD. However, no review identifies whether there is experimental evidence to support the use of this treatment. Objective: Our review aims to determine the efficacy of functional communication training for regulating self-injurious behavior in children and adolescents diagnosed with ASD. Methods: A systematic review was conducted.PubMed, Scopus, Web of Science, and Embase were searched for single-case experimental studies and randomized clinical trials. Result...

“Cotton is the most widely used natural fiber for textiles; however, the capacity of cotton fibers to absorb large amounts of moisture, retain oxygen, and have a high specific surface area makes them more prone to microbial contamination, becoming an appropriate medium for the growth of bacteria and fungi. In recent years, the incorporation of silver nanoparticles in textile products has been widely used due to their broad-spectrum antibacterial activity and low toxicity towards mammalian cells. The aim of the current study is to continue the assessment of our developed nanocomposite and evaluate the antibacterial and antifungal activity of the nanocomposite based on silver nanoparticles and carboxymethyl chitosan (AgNPs-CMC) against Escherichia coli, Staphylococcus aureus, and Candida albicans, evaluated by the well diffusion method. The antibacterial activity against E. coli and S. a...

Cotton is the most widely used natural fiber for textiles but its innate capacity to absorb moisture, retain oxygen, and high specific surface area make it more prone to microbial contamination, becoming an appropriate medium for the growth of bacteria and fungi. In recent years, the incorporation of silver nanoparticles in textile products has been widely used due to their broad-spectrum antibacterial activity and low toxicity towards mammalian cells. The aim of the current study is to synthesize and characterize a nanocomposite based on silver nanoparticles and carboxymethyl chitosan (AgNPs-CMC), which was utilized to provide a functional finish to cotton fabric. The scanning electron microscope (SEM) to produce a scanning transmission electron microscope (STEM) image showed that the nanocomposite presents AgNPs with a 5–20 nm size. The X-ray diffraction (XRD) analysis confirmed the ...

A neural network is a mathematical model that is able to perform a task automatically or semi-automatically after learning the human knowledge that we provided. Moreover, a Convolutional Neural Network (CNN) is a type of sophisticated neural network that has shown to efficiently learn tasks related to the area of image analysis (among other areas). One example of these tasks is image segmentation, which aims to find regions or separable objects within an image. A more specific type of segmentation called semantic segmentation, makes sure that each region has a semantic meaning by giving it a label or class. Since neural networks can automate the task of semantic segmentation of images, they have been very useful for the medical area, applying them to the segmentation of organs or abnormalities (tumors). Therefore, this thesis project seeks to address the task of semantic segmentation of ...

The COVID-19 health crisis posed a new scenario for society, having a ripple effect in, academic areas; to a greater extent, the audiovisual. University entities were ahead of events and proposed TRIC practices that would serve for the times that were to come and that in many cases were ahead of now normalized actions. This research analyzes the cognitive, emotional and social learning acquired by students in quarantine and how the realization of Radio Nebrija in the radio field and Nebrija Talent in the television field, two TRIC projects based on an ABP methodology, served to configure new working models for students and new university dynamics for teachers. The change from ICT context to TRIC is exposed and through a discussion group with young students and in-depth interviews with experts in the field of teaching and learning environments. The effedtiveness od intermethodology in aca...

Edible films for packaging and plastic material replacement purposes are produced based on biodegradable raw materials such as polysaccharides and agents with biological properties, making the final product an alternative for the protection and extension of the shelf life of foods. The main objective of the present research was to evaluate the antioxidant and antimicrobial activity of chitosan biofilms functionalized with muña essential oil. For this purpose, 12 edible films were formulated with 3 concentrations of chitosan (1, 2 and 3%) and 3 of essential oil (0.5, 2 and 5%) including chitosan-only blanks. The antioxidant activity evaluated in biofilms with a higher content of muña essential oil presents more than 60% of DPPH free radical uptake, while in the antimicrobial activity evaluated by petri dishes grown with Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli...

The loss of biodiversity and the effects of climate change hurt agricultural production and food security in Peru and around the world. The family farming sector in Peru (97% of agricultural units – AU) faces numerous challenges when it comes to sustainably producing food. To sustain Peruvian agriculture in the face of climate change, climate-smart agricultural (CSA) practices and agrobiodiversity conservation are essential. This document characterizes the level of agrobiodiversity (index IDA) of family AUs in the Crisnejas basin and analyzes the impact of the elements that affect farmers’ decisions to apply multiple CSA measures. CSA adoption decisions were analyzed using an econometric analysis framework combining multivariate and ordered probit models for 340 family AUs. Results indicate that AUs with a lower agrobiodiversity index (IDA) have a higher monthly income (IDA = 0.56, 3...

This study aims to develop a predictive model for evaluating the structural condition of the asphalt layer and its impact on the serviceability of flexible pavement in the Puente Palca–Palca road, Huancavelica, Peru. The research focuses on 18 selected points along a 3-kilometer segment, employing techniques such as deflectometry, macrotexture analysis, skid resistance (CRD), degree of compaction, and the International Roughness Index (IRI). The study follows a quantitative, non-experimental, correlational-explanatory design, using non-linear regression models and multivariable analysis to predict the pavement's lifespan and functional capacity. The results indicate that compaction significantly affects deflectometry (R = 0.543), while asphalt content inversely influences macrotexture (R² = 0.5648). A critical reduction in surface texture (<1.0 mm) occurs when asphalt content excee...

The Total Solar Irradiance (TSI) is the total amount of solar energy present per square unit every moment beyond the atmosphere, so it's changing every time along the year, although for many practical purposes its average is taken and has been called: The Solar Constant (1367 W/m2). In this paper, the historical efforts made to quantifcate the TSI are reviewed, the latest advances in this matter are presented and a new method to calculate its monthly average based on the SunSpot Number is proposed to apporach to its value as close as 0.05. W/m2 (RMS = 0.002).
