The use of disposable screen-printed electrodes (SPEs) has extraordinarily grown in the last years.In this paper, conductive inks from scrapped SPEs were removed by acid leaching, providing high value feedstocks suitable for the electrochemical deposition of Ag, Pt and Ag core-Pt shell-like bimetallic (AgPt) nanoparticles, onto screen-printed carbo
Artificial perches increase bird-mediated seed rain in agricultural fallow area in southern Brazil
One of the main barriers to restoration is the arrival of diaspores in degraded areas.However, this process can be hampered in open areas without trees in the landscape.For that, artificial perches are used to attract and provide a landing area for avian seed dispersers, to enhance seed rain.Our objective was to evaluate the effect of the distance
Corrosion Induced Morphology Evolution in Stressed Solids
Corrosion morphology is a key factor that influences the reliability and service life of a structure.As most structures service under stress corrosion, there is a great need to understand the effect of stress on the formation conditions of different morphologies.This paper introduces a numerical method to simulate the evolution of surface morpholog
Pneumocystis carinii pneumonia, pulmonary tuberculosis and visceral leishmaniasis in an adult HIV negative patient
This is a case report of a 29 year old male with pneumocystis pneumonia and tuberculosis, and who was initially suspected of having HIV infection, based on risk factor analyses, but was subsequently shown to be HIV negative.The patient arrived at the hospital with fever, cough, weight loss, loss of appetite, pallor, and arthralgia.In addition, he w
