Solvent and catalyst effect in the formic acid aided lignin-to-liquids
(Elsevier, 2018-09-13)
[EN] The effect of the type of solvent, ethanol or water, and a Ru/C catalyst were studied in the formic acid aided lignin conversion. The best results were obtained in the presence of the Ru/C catalyst and using ethanol ...
Small Form-Factor Driver for Power LEDs Powered with One Element Battery
(Springer, 2011)
The present paper is focused on designing small form-factor drivers for high-power LEDs, which are fed with one battery element. Standard power supply architectures are not suitable due to the design requirements and ...
Pb(II) Induces Scramblase Activation and Ceramide-Domain Generation in Red Blood Cells
(Nature Publishing, 2018-05-10)
The mechanisms of Pb(II) toxicity have been studied in human red blood cells using confocal microscopy, immunolabeling, fluorescence-activated cell sorting and atomic force microscopy. The process follows a sequence of ...
Mixing brain cerebrosides with brain ceramides, cholesterol and phospholipids
(Nature Publishing, 2019-09-16)
The properties of bilayers composed of pure brain cerebroside (bCrb) or of binary mixtures of bCrb with brain ceramide, cholesterol, egg phosphatidylcholine or brain sphingomyelin have been studied using a combination of ...
Multiple-Criteria Decision-Making Tool for Local Governments to Evaluate the Global and Local Sustainability of Transportation Systems in Urban Areas: Case Study
(ASCE, 2017-10-24)
Efficient management of urban transportation systems is a challenge for any local government that wishes to improve public wellbeing and comfort. With that end in mind, this paper proposes a tool for decision making and ...
Speed deficiency in shipbuilding contracts from the point of view of an efficient managing of the main engine
(University of Santander, 2010)
This article is related to the shipbuilding contracts and its purpose is to provide amethod of calculation of the economical damages sustained by a purchaser due tothe speed deficiency of the vessel delivered by the shipyard. ...
Some characterizations of the tensor product of complete lattices with applications to quantales
(Springer, 2018-09-17)
This paper examines tensor products of complete lattices in which one factor is com- pletely distributive. At least five characterizations of complete distributivity involving tensor products of complete lattices are given, ...
Combined Fluorescent-Chromogenic In Situ Hybridization for Identification and Laser Microdissection of Interphase Chromosomes
(Public Library of Science, 2013)
Chromosome territories constitute the most conspicuous feature of nuclear architecture, and they exhibit non-random distribution patterns in the interphase nucleus. We observed that in cell nuclei from humans with Down ...
Stability of CuZnOAl2O3/HZSM-5 and CuFe2O4/HZSM-5 catalysts in dimethyl ether steam reforming operating in reaction-regeneration cycles
(Elsevier, 2014-05-21)
The study focuses on the regenerability of bifunctional catalysts prepared with different metallic functions (CuZnOAl2O3 and CuFe2O4 spinel) and HZSM-5 zeolite (SiO2/Al2O3 = 30) as the acid function. These catalysts have ...
Steam reforming of raw bio-oil in a fluidized bed reactor with prior separation of pyrolytic lignin
(ACS, 2013-11-11)
The effect operating conditions (temperature, steam/carbon molar ratio and space-velocity) have on the steam reforming of raw bio-oil has been studied in a two-step reaction unit. In the first step (operated at 500 ºC), a ...
