Abstract Santiago and Chicago are two distant cities but connected by their housing and land market policies. These relationships were at the center of the exhibition The Plot: Miracle and Mirage curated by Alejandra Celedón, Nicolás Stutzin and Javier Correa for the 2019 edition of the Chicago Architecture Biennial "... and other such stories ...". The curatorial operation was twofold: the first maneuver was to look at the past through archival work focused on statements about the city made by the Chicago Boys and their followers. The second was to examine and to audiovisual record the current city looking for symptoms of an implicit urban model, barely pronounced. Although the city of the film is Santiago present, the images are the effects of past politics. The city and its evidence -present and past- became traces of a retroactive manifesto on Santiago.

Resumen Santiago y Chicago son dos ciudades distantes, pero conectadas por sus políticas de vivienda y mercado de suelo. Estas relaciones estuvieron al centro de la exhibición The Plot: Miracle and Mirage curada por Alejandra Celedón, Nicolás Stutzin y Javier Correa para la edición 2019 de la Bienal de Arquitectura de Chicago “...and other such stories...”. La operación curatorial fue doble: la primera maniobra fue dirigir la mirada al pasado a través de un trabajo de archivo centrado en declaraciones sobre la ciudad realizadas por los Chicago Boys y sus seguidores. La segunda fue examinar y registrar audiovisualmente la ciudad actual buscando los síntomas de un modelo urbano implícito, escasamente pronunciado. Si bien la ciudad del filme es Santiago actual, las imágenes son efectos de políticas pasadas. La ciudad y su evidencia -presentes y pasadas- se volvieron huellas de un manifiesto retroactivo sobre Santiago.

Proteins have been traditionally out of reach of electronic structure methods. But with technological advances in the development of powerful computers and the need to extend the methods of computational chemistry to problems of biological interest, such as the rational design of drugs, new technologies in silico have been developed that allow to study condensed systems of phase, which consist of thousands of atoms. Here, there are some techniques that combine two or more methods of calculating in a calculation that allows precise chemical exploration of very large systems. The aim of this work is to find the binding affinity of CDK2 inhibitors calculating their electronic densities and then comparing the similarities of these with the biological activity of ligands developing a QSAR in order to establish correlations between quantum similarity, which is a physical-chemical property and biological activity of said set of molecules that change their properties by varying any of their substituents.

ABSTRACT Vespula germánica (F.) has a negative impact on agriculture, beekeeping, and tourism in Chile. Therefore, environmentally-friendly strategies need to be implemented to control this serious pest. The objective of this study was to evaluate the response of adults of V. germanica to different types of baits with acetic acid + isobutanol (AAIB) added. The selected baits were: blood and bone flour (BF), raspberry jam (RJ), and sweet condensed milk (CM). The trial was conducted in a severely infested site in central Chile. Mixtures were placed in bottle traps. All of the traps were monitored daily from Monday to Friday during 5 weeks, and rebaited every week. A randomized complete block design, with 12 treatments and 4 replicates was used. Captures of V. germanica and other social hymenopterans were identified and data were recorded; V. germanica individuals approaching the trap openings (= visits) were also counted. A number of 15,480 V. germanica individuals, which were mostly workers, were captured. The most attractive baits were CM and BF + 2 mL AAIB. Feeding baits attracted significantly more workers with increasing concentrations of chemicals (AAIB), and significantly more wasps than the feeding baits alone. Lesser captures occurred of Apis mellifera workers (1,046), while the preference trend differed from that observed for V. germanica in several treatments. A number of 854 Polistes buyssoni workers were captured, but no differences were found between treatments. In addition, a number of 466 V. germanica visited the traps, but the trend observed with captures only occurred in traps baited with BF + AAIB, whereas no preference trend was observed for mixtures with RJ and CM. The results indicate that these attracting baits can be used not only to massively and selectively capture and destroy adults of V. germanica, but also to develop feeding baits not attractive for A. mellifera.
