Development of highly porous activated carbon from Jacaranda mimosifolia seed pods for remarkable removal of aqueous-phase ketoprofen
(Elsevier, 2021)
Acceso restringido
In this work, a high porous activated carbon from Jacaranda mimosifolia was developed and employed for ketoprofen adsorption. After the pyrolysis process at 973.15 K, the material presented cavities with different sizes ...
Multiple relationships between aerosol and COVID-19: A framework for global studies
(Elsevier, 2021)
Acceso abierto
COVID-19 (Corona Virus Disease 2019) is a severe respiratory syndrome currently causing a human global pandemic. The original virus, along with newer variants, is highly transmissible. Aerosols are a multiphase system ...
Identification of hazardous nanoparticles present in the Caribbean Sea for the allocation of future preservation projects
(Elsevier, 2021)
Acceso restringido
The deposition of remaining nanoparticles in the Caribbean Sea generates the formation of potentially dangerous elements, which influence at the imbalance of ecosystems. The detection of nanoparticles is not simple and the ...
Semantic Segmentation Using Convolutional Neural Networks for Volume Estimation of Native Potatoes at High Speed
(Springer, 2021)
Acceso restringido
Peru is one of the main producers of a wide variety of native potatoes in the world. Nevertheless, to achieve a competitive export of derived products is necessary to implement automation tasks in the production process. ...
Incidence of lung cancer and mortality among civil construction industry workers: A protocol for a systematic review and meta-analysis
(Public Library of Science, 2021)
Acceso abierto
Background The construction sector is one of the most stable growth industries in the world. However, many studies have suggested an association between occupational exposure in civil construction and lung cancer risk. ...
Venezuelan Forced Migration to Peru During Sociopolitical Crisis: an Analysis of Perceived Social Support and Emotion Regulation Strategies
(Springer, 2021)
Acceso abierto
While many studies have examined the impact of forced migration on Venezuelan migrants in Latin America, to date scholars have not examined the effect of certain coping mechanisms, namely social support and emotion regulation. ...
Dispersion of hazardous nanoparticles on beaches around phosphogypsum factories
(Elsevier, 2021)
Acceso abierto
Anthropogenic occurring nanoparticles (NPs) have been one of the principal catalytic components of marine pollution throughout its history. The phosphogypsum (PG) factories present environmental risks and evident marine ...

Acceso abierto
Objective: The objective of this study is to assess gender representation in food and beverage print advertisements. Results: The study follows a quantitative descriptive approach. Using a content analysis technique, we ...
Comparative carbon emission assessments of recycled and natural aggregate concrete: Environmental influence of cement content
(Elsevier, 2021)
Acceso abierto
This work examines the environmental and geochemical impact of recycled aggregate concrete production with properties representative for structural applications. The environmental influence of cement content, aggregate ...
Two-Dimensional Analysis of Size Effects in Strain-Gradient Granular Solids with Damage-Induced Anisotropy Evolution
(American Society of Civil Engineers (ASCE), 2021)
Acceso restringido
We analyze in two dimensions the mechanical behavior of materials with granular microstructures modeled by means of a variationally formulated strain-gradient continuum approach based on micromechanics and show that it can ...
