Nonfluorescent RNA In Situ Hybridization Combined with Antibody Staining to Visualize Multiple Gene Expression Patterns in the Embryonic Brain of Dro…
2013
In Drosophila, the brain arises from about 100 neural stem cells (called neuroblasts) per hemisphere which originate from the neuroectoderm. Products of developmental control genes are expressed in spatially restricted domains in the neuroectoderm and provide positional cues that determine the formation and identity of neuroblasts. Here, we present a protocol for nonfluorescent double in situ hybridization combined with antibody staining which allows the simultaneous representation of gene expression patterns in Drosophila embryos in up to three different colors. Such visible multiple stainings are especially useful to analyze the expression and regulatory interactions of developmental cont…
Anticipated future of Latvia and Russia during a global economic crisis: A mixed methods perspective
2014
This cross-cultural study explored subjective predictors of more positive evaluation of the future of the country during a global socioeconomic crisis. A sequential mixed-method design was chosen for an exploration of students? expectations in Russia and Latvia as countries contrasting in macro-contextual conditions. In 2009, Study 1 was designed as a thematic analysis of essays on topic ?The Future of Latvia/Russia?. The results demonstrated that the future of a country is anticipated by taking into account external influences, the present of the country, and its perceived power and stability. In 2011, Study 2 involved these themes as independent variables in a multiple regression model. T…
Propuestas de intervención en las aulas desde el Discurso de los derechos Humanos
2018
Entendemos la Educación para los Derechos Humanos como un proceso educativo progresivo, continúo y preciso, que se extiende a lo largo de toda la vida y se basa en los principios del desarrollo democrático garantizando la libertad del ser humano y apelando a la justicia. Desde el contexto educativo formal se trabaja para que la participación activa y cívica de los menores sea una realidad. El currículo escolar y los objetivos que se fijan desde las instituciones educativas se orientan hacia el desarrollo global del individuo, donde la Educación para los Derechos Humanos fundamenta los procesos de enseñanza aprendizaje. Existen líneas metodológicas que se basan en sus principios, es el caso …
SISTEMI DI COPERTURE INNOVATIVE NEI CONTESTI ANTICHI
2014
La ricerca è indirizzata al tema delle coperture in vetro a protezione di siti archeologici. Tale scelta è stata influenzata dalle seguenti considerazioni: gli ultimi decenni sono stati caratterizzati da un incremento delle coperture trasparenti protettive; il tema delle strutture di copertura in contesti archeologici e ciò che riguarda la loro progettazione, è stato, e continua ad essere oggi, molto dibattuto tra gli esperti in tutto il mondo; la costante evoluzione tecnologica del vetro continua a incrementare le sue possibilità d’uso in architettura. Tale materiale presenta numerosi vantaggi come l’apparente leggerezza e la trasparenza ma in ambito archeologico pone problematiche che rig…

Understanding moderating effects in increasing share-of-wallet and word-of-mouth : A case study of Lidl grocery retailer
2018
This study examines how five moderating variables (the length of the customer relationship, following a company in print media and on social media, remembering online advertisements, and the customer’s age) affect the relationships between perceived value and loyalty and satisfaction and loyalty in the grocery retailing sector. A series of hypotheses were developed and tested with a sample of 2,072 discount retailer customers in Finland. The results support all the direct effects hypotheses and show that perceived value and satisfaction both have a positive effect on loyalty, measured as a share of wallet and word of mouth and that the effect of perceived value tends to be stronger in the s…
The Gaia-ESO Survey: The origin and evolution of s-process elements
2018
Context. Several works have found an increase of the abundances of the s-process neutron-capture elements in the youngest Galactic stellar populations. These trends provide important constraints on stellar and Galactic evolution and they need to be confirmed with large and statistically significant samples of stars spanning wide age and distance intervals. Aims. We aim to trace the abundance patterns and the time evolution of five s-process elements - two belonging to the first peak, Y and Zr, and three belonging to the second peak, Ba, La, and Ce - using the Gaia-ESO IDR5 results for open clusters and disc stars. Methods. From the UVES spectra of cluster member stars, we determined the ave…
Neutral Iron Emission Lines From The Day-side Of KELT-9b -- The GAPS Programme With HARPS-N At TNG XX
2020
We present the first detection of atomic emission lines from the atmosphere of an exoplanet. We detect neutral iron lines from the day-side of KELT-9b (Teq $\sim$ 4, 000 K). We combined thousands of spectrally resolved lines observed during one night with the HARPS-N spectrograph (R $\sim$ 115, 000), mounted at the Telescopio Nazionale Galileo. We introduce a novel statistical approach to extract the planetary parameters from the binary mask cross-correlation analysis. We also adapt the concept of contribution function to the context of high spectral resolution observations, to identify the location in the planetary atmosphere where the detected emission originates. The average planetary li…
Three-Dimensional Simulations of Solar Wind Preconditioning and the 23 July 2012 Interplanetary Coronal Mass Ejection
2020
Predicting the large-scale eruptions from the solar corona and their propagation through interplanetary space remains an outstanding challenge in solar- and helio-physics research. In this article, we describe three dimensional magnetohydrodynamic simulations of the inner heliosphere leading up to and including the extreme interplanetary coronal mass ejection (ICME) of 23 July 2012, developed using the code PLUTO. The simulations are driven using the output of coronal models for Carrington rotations 2125 and 2126 and, given the uncertainties in the initial conditions, are able to reproduce an event of comparable magnitude to the 23 July ICME, with similar velocity and density profiles at 1 …
Estudio comparativo: la atenuación en el español de Valencia y de La Habana
2018
RESUMEN En este trabajo se ha llevado a cabo un análisis comparativo de la atenuación pragmática entre un corpus de conversaciones coloquiales del español de Valencia (España) y otro del español de La Habana (Cuba). El objetivo de este estudio es observar el contraste de uso de esta estrategia pragmática, por un lado, entre ambas zonas geográficas, y, por otro, en relación a la edad de los hablantes, de 35-55 años. Para ello, se han tomado dos conversaciones del corpus Val.Es.Co (Briz et alii, 2002) y una conversación propia grabada en 2018, y para el español de La Habana se han analizado tres conversaciones del corpus Ameresco (http://esvaratenuacion.es/corpus-discursivo-propio/), en el qu…
