Energy harvesting from vehicular traffic over speed bumps: A review [PDF]

open access: yes, 2018
Energy used by vehicles to slow down in areas of limited speed is wasted. A traffic energy-harvesting device (TEHD) is capable of harvesting vehicle energy when passing over a speed bump. This paper presents a classification of the different technologies

EFEITOS DE SURFACTANTES NA ORGANOFILIZAÇÃO DE ARGILAS BENTONÍTICAS PARA USO EM FLUIDOS DE PERFURAÇÃO DE BASE MICROEMULSIONADA

open access: yesHolos, 2018
A principal indústria consumidora da argila bentonítica é a indústria petrolífera, pois a utiliza como viscosificante de fluidos de perfuração tanto base água quanto base óleo, sendo, neste último, necessário submeter o argilomineral a um processo ...

How do I implement a whole blood program with low blood wastage?

open access: yesTransfusion, Volume 65, Issue 11, Page 2014-2020, November 2025.
Abstract Background The use of low‐titer O whole blood (LTOWB) is requested in the treatment of major bleeding, initially used in military medicine but now increasingly utilized in civilian prehospital care. The advantage is the administration of a balanced transfusion, red blood cells, coagulation factors, and platelets, in one bag. The challenges are

The crucial role of meshing in computational fluid dynamics simulations for organic geometries in paleobiology: Describing fluid dynamics performance through best practices

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2170-2194, October 2025.
Abstract Computational fluid dynamics (CFD) has become an essential tool for studying fluid interactions in biological systems. While widely used in engineering, its application in the natural sciences, particularly in paleobiology, remains limited due to the challenges of meshing complex organic geometries.

Escribir en comunidad: Construcción de relaciones y responsabilidad en la producción de conocimiento

open access: yesAmerican Anthropologist, Volume 127, Issue 3, Page 447-465, September 2025.
ABSTRACT As anthropology reckons with its past, present, and future, anthropologists increasingly seek to challenge inequities within the discipline and academia more broadly. Anthropology, regardless of subdiscipline, is a social endeavor. Yet research often remains an isolating (though not necessarily solitary) process, even within research teams and

Nonlinear evolution of harmonically forced perturbations on a wingtip vortex [PDF]

open access: yes, 2016
Wingtip vortices are created by flying airplanes due to lift generation. The vortex interaction with the trailing aircraft has sparked researchers’ interest to develop an efficient technique to destroy these vortices.
