Abstract This study investigates the utilization of biodiesel derived from castor seeds and enhanced with 2% of diethyl ether and CeO2 NPs to improve engine performance and reduce emissions.Various fuel blends, including biodiesel-diesel mixtures with and without nanoparticles, were tested under fixed load conditions.Results indicate that adding Ce
Robot Operations for Pine Tree Resin Collection
A robotic technology consisting of an industrial robot mounted on an autonomous rover used to tap slash pine trees and collect their oleoresin for processing is introduced, and the technological challenges related to the robotic operations are discussed in detail.Unlike the case of industrial automated manufacturing systems where the relative posit
Acanthamoeba protease activity promotes allergic airway inflammation via protease-activated receptor 2.
Acanthamoeba is a free-living amoeba commonly present in the environment and often found in human airway cavities.Acanthamoeba possesses strong proteases that can elicit allergic airway inflammation.To our knowledge, the aeroallergenicity of Acanthamoeba has not been reported.We repeatedly inoculated mice with Acanthamoeba trophozoites or excretory
Implications and Consequences of the Arms Trade Treaty (ATT)
The international sales volume of conventional arms has been considerably increasing, making it nightstick twm-850xl necessary to create an international normative framework of regulations: the adoption of the ATT by the United Nations (U.N.) General Assembly (2013) represents a historical achievement to establish global standards for the arms trad
