Sistema autónomo de monitoreo y suministro de agua en plantas de ornato

El cuidado al medio ambiente es una tarea que se debe realizar buscando estrategias para concientizar a la sociedad, fomentando una responsabilidad social. Es por ello que en este trabajo se plantea el sistema de un desarrollo autónomo capaz de mantener en condiciones óptimas el crecimiento y vida de las plantas de ornato. Otro factor importante es la influencia del sector laboral primario en el ámbito de desarrollo económico, por lo que es importante la implementación de nuevas tecnologías con el fin de desarrollar y optimizar los niveles de producción del sector primario. En este trabajo se propone un sistema diseñado mediante la teoría de control moderno el cual ayuda a la optimización del gasto de agua en una planta de ornato. Para esto se desarrollará un sistema de riego autónomo con la capacidad de regular el suministro de agua, estableciendo un monitoreo mediante una conexión con dispositivos móviles. Además, se busca la implementación de tecnología mexicana diseñada con la finalidad de incursionar en el ámbito de la manutención de plantas de ornato mediante la utilización de herramientas y equipo de bajo costo

Empathic stories to address intergroup discrimination towards undocumented Latinx Immigrants: Stories when we cannot live experiences

A growing body of research in social psychology focuses on ameliorating intergroup discrimination. A substantial amount of this work originates from the contact hypothesis (Allport, 1954). However, many indirect contact studies utilize stories as interventions or cite other studies that use stories. The work in narrative psychology shows that stories provide consumers the opportunity to rehearse intergroup interactions (Oatley, 1999), induce empathy that allows for understanding and feeling the experiences of others (Van Laer et al., 2014), and provide mental experiences felt as if truly occurring (i.e., transportation; Green & Brock, 2000, 2002). Two focal questions of the current research are whether stories and their processes are already effective in reducing intergroup discrimination and whether stories and indirect contact strategies might overlap. The current study explored the effectiveness of stories in reducing different aspects of discrimination (i.e., behaviors, attitudes, and perceptions) towards both undocumented Latinx immigrants (i.e., a group) and to an undocumented Latina immigrant (i.e., an individual), while testing transportation as a driver of the effect. This between subjects design compared three stories including A) a story with somatosensory cues (i.e., in-depth physiological descriptions of the experience of an undocumented Latina immigrant, non-DACA recipient), B) the same story without somatosensory cues, and C) positive statistics and facts about immigrant’s contributions to the US, as a comparison group. The hypotheses tested included: First, the effectiveness of stories in inducing transportation, influencing monetary donations to an immigrant fund, increasing ratings of warmth and competence, and inducing more positive attitudes, compared to the provision of supportive statistics. Second, the effectiveness of the enhanced stories, over statistics, in inducing transportation, donations, increasing ratings of warmth and competence, and in inducing more positive attitudes. Third, the effectiveness of the enhanced story, over the non-enhanced story, in inducing transportation, donations, increasing ratings of warmth and competence, and in inducing more positive attitudes to the character of the story. Finally, whether transportation would moderate the relationship between the clip condition and donations, ratings and warmth and competence, and attitudes to the central character’s membership group—undocumented Latinx immigrants. These hypotheses were tested on a sample of MTurk workers (N= 572) over the age of 18 found in states with an overall population of Latinx below five percent. The results confirmed that individuals in story conditions did undergo more transportation and had higher average donations, but these did not differ in ratings of warmth and competence, or attitudes to undocumented Latinx immigrants. Regarding the character, participants in the enhanced story condition rated her as more competent and less negatively than those in non-enhanced story condition, while also rating her low in warmth. Finally, one moderation analysis showed that respondents in story conditions reported more positive attitudes towards undocumented Latinx immigrants only if they were more transported. Together, these results, indicate that stories could be effective in increasing positive attitudes towards groups that are targets of vitriol, and more importantly that a story process such as transportation may play a role in this positive attitude induction

Characterization of the killer toxin KTCf20 from wickerhamomyces anomalus, a potential biocontrol agent against wine spoilage yeasts

Wickerhamomyces anomalus Cf20 secretes the killer toxin KTCf20 that inhibits several wine spoilage yeasts of the species Pichia guilliermondii, P. membranifaciens, Brettanomyces bruxellensis and Dekkera anomala. KTCf20 binds cell wall extracts from the sensitive target P. guilliermondii Cd6; however, this capacity was lost when cell wall extracts were pre-treated with fungal β-glucanase. Pustulan and laminarin inhibited killer activity, suggesting that β-1,3 and β-1,6-glucans may be the putative binding sites for KTCf20 on the cell wall of sensitive cells. The toxin was produced and showed to be stable and highly active at physicochemical conditions suitable for winemaking process. In addition, the strain Cf20 is compatible with Saccharomyces cerevisiae in co-culture conditions being potential its application in a mixed starter culture. These data suggest that W. anomalus Cf20 and/or KTCf20 are promising biocontrol agents against spoilage yeasts during wine-making process.Fil: Fernandez de Ullivarri, Miguel.

EEG Long-Term Dynamics to Measure Progress of Concurrent Patients in Drug-Resistant Childhood Syndromes

It is well known that in order to study the evolution of a drug-resistant epilepsy, it is necessary to practice a lot of Electroencephalographic signals (EEG) studies during the child’s life. The number of EEG collected by parents during the child’s life might easily range between 10 and 20, depending of the severity of the affection, age and neurologist’s requirements. With all these data, natural questions posed by parents and physicians are as follows: (a) Which zone of the brain has been the most affected so far? (b) On which year was the child better? Naturally, the neurologist would wish to correlate these answers with the prescribed drugs history but responding objectively those questions is certainly not easy (or even impossible). However, both questions were already answered quantitatively in [1] where a very difficult case of Doose syndrome (DS) was investigated. In this work, we propose to go further answering an additional question frequently posed by parents and physicians which is as follows: (c) How bad is our child with respect to other with similar affections? Note that replying this question results also very difficult because this would imply to compare sets of multiple, massive EEG (one for every kid involved in the study). In addition, the possibility of answering this question also implies to compare medications/results among all the children in the investigation. What we propose here is to answer quantitatively question (c) by using our complexity measures and indices introduced here and the experience obtained in [1] with all this linked to medications. The question arises as follows: Why to use complexity, that is, entropy to characterize EEG information? Because it would be formidable to determine a mathematical model which could represent in general, each case of DS or LGS. This is not yet possible but after analyzing a set of nonlinear models, we concluded that it is more reliable to work with nonlinear statistics (entropies) to extract information from EEG in children epilepsy [1]. As a result of this, we offer here the multiscale entropy (MSE) index and the bivariate multiscale (BMSE) index to evaluate all channels of multiple EEG

¿Qué es el control avanzado?

Un sistema de control es un componente integral de cualquier sistema industrial y es necesario para dar economía y utilidad al producto del sistema. La ingeniería de control es igualmente aplicable a la aeronáutica, química, mecánica, medioambiente, civil, electrónica, eléctrica, etc. Ahora en día la ingeniería de control es un área de carácter multidisciplinario, tanto en la teoría como en la práctica. El control es la operación de mantener el estado del resultado de un sistema al nivel deseado; por ello, el sistema de control utiliza la información de salida para controlar el flujo de la materia y la energía a través del sistema. Esto nos define la importancia del control: seguridad, especificaciones del producto, regulaciones ambientales, limitantes de operación, economía y consistencia en el comportamiento del sistema. Entre mejor es el criterio para el tipo de control aplicado al sistema, mejores serán los resultados

Wolf spider burrows from a modern saline sandflat in central Argentina: Morphology, taphonomy and clues for recognition of fossil examples

Pavocosa sp. (Lycosidae) burrows found in an open sparsely vegetated area on the edge of the Gran Salitral saline lake, in central Argentina, are described. Burrows were studied by capturing the occupant and casting them with dental plaster. The hosting sediments and vegetation were also characterized. Inhabited Pavocosa sp. burrows display distinctive features as open, cylindrical, nearly vertical, silk lined shafts about 120 mm long, subcircular entrances, a gradual downward widening, and a particularly distinctive surface ornamentation in the form of sets of two linear parallel marks at a high angle to the burrow axis. Instead, casts of vacated Pavocosa sp. burrows showed some disturbances caused either by the reoccupation by another organism or by predation of the dweller. Two morphologies are related to reoccupation of burrows: those with a structure in form of an ``umbrella'' and another with smaller excavations at the bottom of the burrow. Predation by small mammals produces funnel-shaped burrows. Both active and abandoned Pavocosa sp. burrow casts are compared with existing ichnogenera and inorganic sedimentary structures, highlighting its distinction. It is argued that key features like the presence of a neck, a downward widening and the described surface texture will allow recognition of wolf spider burrows in the fossil record. However, the putative spider burrows described in the literature either lack the necessary preservational quality or do not show ornamentation similar to the modern wolf spider burrows. Fossil wolf spiders are recorded since the Paleogene (possibly Late Cretaceous), therefore Cenozoic continental rocks can contain wolf spider burrows awaiting recognition. In addition, the particular distribution of Pavocosa sp. in saline lakes may imply that this type of burrow is linked to saline environments.Fil: Mendoza Belmontes, Fatima del Rosario.

Inflation expectation indicators based on financial instrument prices

Artículo de revistaThis article shows how indicators of agents’ inflation expectations can be derived from the prices of various financial instruments and presents the estimates obtained for the euro area and the United States. The results show that these metrics have reacted to economic and monetary decisions made in recent years, and that, on average, expected inflation is lower and less volatile in the euro area than in the United States. Moreover, since end-2016 there has been a marked rise in the probability of observing longterm inflation rates above 2% in the United States, coinciding with the likely change in the country’s economic policy stance. Changes in the indicators for the euro area have been less pronounced over this period, although a marked drop in the probability of low or negative inflation rates has been observe
