Vortex dynamics and scalar transport in the wake of a flat-plate controlled by a vibrating trailing-edge flap
(Elsevier, 2020)
We investigate the onset and development of vortical flow disturbances introduced into the wake of a horizontally fixed flat-plate by means of the controlled motion of a trailing edge flap. The vibrating mechanics of the ...
Occurrence of killer yeast strains in industrial and clinical yeast isolates
(SOC BIOLGIA CHILE, 2008)
The secretion of proteinaceous toxins is a widespread characteristic in environmental and laboratory yeast isolates. a phenomenon called "killer system". The killer phenotype (K+) call be encoded by extrachromosomal genetic ...
Modelling hydrogen production by the rich combustion of heavy fuel oil
(Pergamon-Elsevier Science, 2016)
This paper reports on a modelling study of the rich combustion of heavy fuel oil in a reactor packed with an inert porous medium. Decalin is used as a model compound to represent the heavy fuel oil. A computational model ...
Regional alteration of cholinergic function in central neurons of trisomy 16 mouse fetuses, an animal model of human trisomy 21 (Down syndrome)
(1994)
The trisomy-16 (TS16) mouse is considered to be a model of human trisomy 21 (Down syndrome) because of genetic homology between mouse chromosome 16 and human chromosome 21. We examined cholinergic function of brain and ...
Discovery of an extremely high velocity, massive, and compact molecular outflow in Norma
(UNIV CHICAGO PRESS, 2008-01-01)
G331.5-0.1 in the Norma spiral arm is one of the most luminous and extended cores of a giant molecular cloud (GMC), containing at least six massive and dense dust condensations. Here we report the discovery, from observations ...
Voltammetric studies of aromatic nitro compounds: pH-dependence on decay of the nitro radical anion in mixed media
(ELSEVIER SCIENCE, 2000-12-01)
In this report we have chosen ethyl-m-nitrobenzoate (EMNB) as a prototype of a nitroaromatic compound in order to carry out a detailed cyclic voltammetric study focused on the coupled chemical reaction of the generated ...
Comparative study of the electrocatalytic activity of cobalt phthalocyanine and cobalt naphthalocyanine for the reduction of oxygen and the oxidation of hydrazine
(Elsevier Ltd, 1998)
Cobalt phthalocyanine (CoPc) and cobalt naphthalocyanine (CoNPc) exhibit different redox and electronic properties. Redox processes on CoPc are more reversible than on CoNPc. The pH dependence of those processes is also ...
A high-performance liquid chromatography method for determination 2-(n-(N,N,N-trimethyl)-n-alkyl)-5-alkylfuryl halides in dipalmitoylphosphatidilcholine liposome solutions
(2006)
A high-performance liquid chromatography (HPLC) method for the determination of 2-(4-(N,N,N-trimethyl)-butyl)-5-dodecylfuryl bromide
(DFTA) in dipalmitoylphophatidil-choline (DPPC) liposome solutions has been developed. ...
Deep oxidation of aluminum by a DC oxygen plasma
(ELSEVIER SCIENCE SA, 2005-05-31)
A novel way of oxidising aluminum using a DC oxygen plasma is described. The oxidation is carried out with a pressure of similar to 0.1 bar, an electrical current lower than 3 mA, and a working distance between the electrodes ...
Progesterone synthesis by human luteal cells: Modulation by estradiol
(1994)
To assess the role of estradiol (E2) upon progesterone (P4) synthesis, a well defined human midluteal cell system was used. A dose-dependent inhibition of P4 synthesis with and without hCG was induced by E2. In addition, ...
