The first results of a test with some acute psychotic azacyclonol react are presented in this communication. The azacyclonol is one of the most recent treatment of psychosis drugs. Has an action on the central nervous system, probably by inhibiting serotonin and therefore produces similar effects to reserpine and chlorpromazine. The main activity is to override the clinical and bio-electrical disturbances produced by alucinóqenos drugs (LSD and mescaline). In various toxic psychosis and acute schizophrenic reactions has done away with mental disorders, sometimes in an extremely short time. Certain psychotic reactions have been referred during the first intravenous injection of the preparation. In this work, the first thing you do in the country, azacyclonol used intravenously and orally in 11 cases, 5, suffered from paranoid schizophrenia, paranoid psychosis 3, 2 and 1 toxic psychosis o...

It has been obtained a good quality copper cement from copper-zinc sulphides ores of the east peruvian Andes at Marañon complex zone using integrated metallurgical processes, that makes easier the possibility to give technological value to peruvian concentrates of copper. Monitoring obtained products employing combined techniques such the X-Ray diffraction or the Mössbauer spectroscopy allow us to have a better information of the existing elements and help to control and optimize the metallurgical processes. With the Cementation Cinetic Equation there have been carried out simulations of the process, considering the process related variables, like time, agitation, solution concentration, pH, etc. Recovery has reported up to 70% of copper, that gives the way to improve national ore and concentrate extraction costs and open a great possibility to apply it to postergated small and medium ...

In the context of atmospheric chemistry, two reactions radical-molecule of hydrogen abstraction have been studied. These are the OH' and NO3: radical (oxidizers agents in the troposphere) with formaldehyde in gas-phase. The calculations were carried out using the PM3 and <>. Ab initio methods of the UHF type. The results have allowed us to estimate the corresponding times of tropospheric permanency and the implications of these reactions in the removal of forrnaldehyde and similars from the low atmosphere.

Frente a un estímulo objetivo, las personas procesan mediante la atención selectiva antes de realizar toma de decisiones. Si ese estímulo sufre algún cambio en su configuración 2D o 3D, ¿en qué casos una persona reacciona más rápido o más lento? La presente investigación evaluó la influencia de los cambios en las características de los estímulos en experimentos de tiempos de reacción en tareas de atención visual en videojuegos creados en Unity 3D. Para estudiar esas características, se realizó una comparación entre dos experimentos de videojuegos. El primer experimento se dividió en dos bloques: uno mostraba estímulos en 2D y otro en 3D. Se recolectó el tiempo de reacción de los participantes frente a esos estímulos y se obtuvo que el tiempo de reacción fue mayor en 3D en 28.33 ms. En el segundo experimento se incrementaron los bloques (de dos a ocho) para explic...

Light absorption spectra were used to estímate gold particles growing kinetics following a gold salt (HAuCl4) reduction by sulfite in aqueous solution. Due this process is extremely fast, e.g. part1cles reach 150nm s1ze in less a second, a special equipment denorninated Stopped Flow Reactor (AFR) was used. Light spectra was modeled using Mie theory for monodisperse particles with1n 30-250nm range size, and tor minor sizes experimental spectra of commercial colloids were used, due to uncertainly in dielectric constant for these sizes.Three different approaches were proposed to estimate the gold particles size distribution evolution, and experimental intensity and shape of spectra were used to validate the computation. The most simply approach considers the assumption that particles are compact spheres and monodisperse, following model of LaMer. A second approach is based on growth model ...

In this article will be defended the thesis that parallel trials and social condemnations can often serve as functional equivalents to forensic punishment –most of the times, only partially– and, insofar as they justify a reduction in the formal sentence, should be considered during the judicial sentencing process.To support this argument, which is considered correct if the proportionality of penalties is to be consistently respected, the author will begin with the theory of norms, focusing particularly on the sanction norm; then introduce the theory of functional equivalents to punishment, considering both its factual and expressive dimensions; and finally, analyze how both retributive and preventive aspects, along with considerations of desert and necessity, influence the determination of punishment.

Can political ads produce enough emotional shock as for orienting a person’s vote? To answer this inquiry we monitored a group of first-time voters from different universities in Mexico City during the 2018 electoral process. Through association analysis and multidimensional scaling techniques, we contrasted their emotional response to campaign ads of the three main presidential candidates with their final vote on July 1st. Our results show there is only a slight correlation between emotional reaction to political ads and the vote cast by individuals. Emotions motivated by audiovisual stimuli, have a limited effect over vote orientation, since these reactions depend upon the interpretive capitals that each voter possesses.
