A series of tetrabutyl ammonium (TBA) salts V-included Keggin-type polyoxoanions with W (TBA4PW11V1O40 and TBA5PW10V2O40) Mo (TBA4PMo11V1O40 TBA5PMo10V2O40) as addenda atoms were prepared using a hydrothermal method. These synthesized materials characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), UV-Vis diffuse reflectance (DRS UV-Vis), thermogravimetric analysis (TGA), CHN elemental (EA), inductively coupled plasma spectrometry (ICP-MS), N2...
Intercropping is an agricultural practice commonly used to improve plant nutrition. In this study, we prospected the interaction between root exudates of subterranean clover (Trifolium subterraneum L.) and grapevine (Vitis vinifera L.). This experiment was focused on detection organic acids, amino flavonoids in released by grown separately together. Furthermore, quantified low-molecular-weight acids (LMWOA) exudates. To test effect plant-plant chemical signaling, both species were Hoagland...
This paper proposes a novel matching estimator where neighbors used and weights are endogenously determined by optimizing covariate balancing criterion. The is based on finding, for each unit that needs to be matched, sets of observations such convex combination them has the same values as needing or with minimized distance between them. We implement proposed data from National Supported Work Demonstration, finding outstanding performance in terms balance. Monte Carlo evidence shows our...
Dimethoate, diazinon, parathion methyl, pirimiphos malathion, fenthion, chlorpyriphos, methidathion and azinphos methyl were determined in 71 olive oil samples produced Chile from different varieties of olives (arbequina, frantoio, picual, lechino blend) at three harvest periods (2007, 2008 2009). The target pesticides using a validated analytical method based on microwave-assisted liquid–liquid solid-phase extraction with subsequent GC–FPD detection GC–MS/MS for confirmation purposes. In...
We estimate spatially disaggregated measures of intergenerational mobility in Chile through an administrative dataset linking children's and their parents' earnings from the formal private labour sector. report remarkable heterogeneity as we find higher lower upward mining agricultural regions, respectively, corroborating previous findings by Connolly et al. 2019 with distinction that is a unitary state, implying factors other than institutional differences shape mobility.
A strong oscillation of electoral preferences took place in Chile between the election members Constitutional Convention May 2021 and Council 2023. This is surprising because, until national-scale social uprising 2019, there was a broad consensus that highly institutionalised party system where political tended to be stable. In this research note, we study how choices made by citizens shifted both elections, using ecological inference approach based on Bayesian hierarchical model developed...
This study estimates the effect of between-class ability grouping on Chilean secondary students' academic achievement. We rely a structural feature school system: A considerable number students who complete primary must change schools to start their education. Cardinality matching was performed account for confounding variables. Sensitivity analysis address fact that differences in unobserved variables could bias our findings. Results show attending groups by causes reduction average scores...
