Diseño de estrategias pedagógicas apoyadas en las TIC orientadas a los padres de familia para fortalecer la dimensión personal - social de los niños y niñas del Jardín Infantil Stanford

Esta investigación se realizó en el Jardín Infantil Stanford, donde se evidenció una baja asistencia de los padres de familia a las escuelas para padres presencial, por motivos laborales o falta de tiempo; por lo tanto este proyecto busca dar respuesta a esta problemática por medio del desarrollo de diferentes estrategias pedagógicas con apoyo de las (TIC) a través del diseño de un ambiente virtual de aprendizaje (AVA). Dentro de su implementación se logra que los padres de familia participen activamente en la ejecución de cada actividad propuesta, apoyándolos en el tema de la formación de sus hijos; es por ello que la puesta en marcha del (AVA) fue bien recibida y aporto de manera enriquecedora y significativa, dejando a los padres de familia una experiencia importante de reflexión e interacción

The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data

This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete release of the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, which reached its goal of surveying over 10,000 nearby galaxies. The complete release of the MaNGA Stellar Library (MaStar) accompanies this data, providing observations of almost 30,000 stars through the MaNGA instrument during bright time. DR17 also contains the complete release of the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) survey which publicly releases infra-red spectra of over 650,000 stars. The main sample from the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), as well as the sub-survey Time Domain Spectroscopic Survey (TDSS) data were fully released in DR16. New single-fiber optical spectroscopy released in DR17 is from the SPectroscipic IDentification of ERosita Survey (SPIDERS) sub-survey and the eBOSS-RM program. Along with the primary data sets, DR17 includes 25 new or updated Value Added Catalogs (VACs). This paper concludes the release of SDSS-IV survey data. SDSS continues into its fifth phase with observations already underway for the Milky Way Mapper (MWM), Local Volume Mapper (LVM) and Black Hole Mapper (BHM) surveys

Mutational and non mutational adaptation of Salmonella enterica to the gall bladder

During systemic infection of susceptible hosts, Salmonella enterica colonizes the gall bladder, which contains lethal concentrations of bile salts. Recovery of Salmonella cells from the gall bladder of infected mice yields two types of isolates: (i) bile-resistant mutants; (ii) isolates that survive lethal selection without mutation. Bile-resistant mutants are recovered at frequencies high enough to suggest that increased mutation rates may occur in the gall bladder, thus providing a tentative example of stress-induced mutation in a natural environment. However, most bile-resistant mutants characterized in this study show defects in traits that are relevant for Salmonella colonization of the animal host. Mutation may thus permit short-term adaptation to the gall bladder at the expense of losing fitness for transmission to new hosts. In contrast, non mutational adaptation may have evolved as a fitness-preserving strategy. Failure of RpoS(-) mutants to colonize the gall bladder supports the involvement of the general stress response in non mutational adaptation
