There are few reports on the contamination of total aflatoxins (AFs), AFB1, deoxynivalenol (DON) and zearelenone (ZEA) in maize straw harvested in Mexico; hence, the aim of this study was to determine the concentration of such mycotoxins by immunoassay analytical technique (ELISA) and High-performance liquid chromatography (HPLC) in straw coming from 17 genotypes of white and yellow maize cultivated during 2009 in the municipality of Tepatitlan, Jalisco. Results showed a high percentage of occurrence of total aflatoxins by ELISA (88.2 %) and AFB1 by HPLC (84 %) with average levels of 7.0 ± 3.29 mg Kg-1 and 3.68 ± 2.91 mg Kg-1 respectively; DON determination by ELISA method presented 100 % of positive samples, average concentration was 6.04 ± 3.49 mg Kg-1; regarding the determination of ZEA by ELISA, 98.5 % of positive samples was observed with average levels of 1164.6 ± 1046.7 mg Kg-1 and by HPLC 81 % presented average levels of 544.6 ± 1035 mg Kg-1, no statistical difference was observed among straw of the different genotypes of maize (p>0.05) in any of the analyzed mycotoxins. It is important to mention that none of the samples exceeded the highest level recommended by the Mexican legislation for aflatoxins in feed for animals (20 mg Kg-1), however, 23.5 % (16/68) of the determined samples by HPLC surpassed the limit allowed for AFB1 by the European Community (5 mg Kg-1); 4.4 % (3/68) surpassed the levels allowed by DON (12 mg Kg-1); while ZEA showed 11.8 % (8/68) of samples detected for ELISA and 10.3 % (7/68) by HPLC with levels that exceed those recommended by the European Commission (2000 mg Kg-1), there is no regulation in Mexico for these mycotoxins. ; Fil: Patricio, S.

This article advocates for a comparative approach to archaeological studies of colonialism that considers how Native American societies with divergent political economies may have influenced various kinds of processes and outcomes in their encounters with European colonists. Three dimensions of indigenous political economies (polity size, polity structure, and landscape management practices) are identified as critical variables in colonial research. The importance of considering these dimensions is exemplified in a case study from California, which shows how small-sized polities, weak to moderate political hierarchies, and regionally oriented pyrodiversity economies played significant roles in the kinds of colonial relationships that unfolded. The case study illustrates how the colonial experiences of Native Californians differed from those of other tribal groups that confronted similar kinds of colonial programs involving Franciscan missionaries elsewhere in North America. The article stresses that the archaeology of colonialism is not simply an arcane academic exercise but, rather, has real-life relevancy for people who remain haunted by the legacies of colonialism, such as those petitioning for federal recognition in California.

We report the detection of a Neptune-mass exoplanet around the M4.0 dwarf GJ 4276 (G 232-070) based on radial velocity (RV) observations obtained with the CARMENES spectrograph. The RV variations of GJ 4276 are best explained by the presence of a planetary companion that has a minimum mass of mb sin i 16 M on a Pb = 13.35 day orbit. The analysis of the activity indicators and spectral diagnostics exclude stellar induced RV perturbations and prove the planetary interpretation of the RV signal. We show that a circular single-planet solution can be excluded by means of a likelihood ratio test. Instead, we find that the RV variations can be explained either by an eccentric orbit or interpreted as a pair of planets on circular orbits near a period ratio of 2:1. Although the eccentric single-planet solution is slightly preferred, our statistical analysis indicates that none of these two scenarios can be rejected with high confidence using the RV time series obtained so far. Based on the eccentric interpretation, we find that GJ 4276 b is the most eccentric (eb = 0.37) exoplanet around an M dwarf with such a short orbital period known today.© ESO 2019. ; CARMENES is an instrument for the Centro Astronomico Hispano-Aleman de Calar Alto (CAHA, Almeria, Spain).

In response to the 2013 Update of the European Strategy for Particle Physics, the Future Circular Collider (FCC) study was launched, as an international collaboration hosted by CERN. This study covers a highest-luminosity high-energy lepton collider (FCC-ee) and an energy-frontier hadron collider (FCC-hh), which could, successively, be installed in the same 100 km tunnel. The scientific capabilities of the integrated FCC programme would serve the worldwide community throughout the 21st century. The FCC study also investigates an LHC energy upgrade, using FCC-hh technology. This document constitutes the second volume of the FCC Conceptual Design Report, devoted to the electron-positron collider FCC-ee. After summarizing the physics discovery opportunities, it presents the accelerator design, performance reach, a staged operation scenario, the underlying technologies, civil engineering, technical infrastructure, and an implementation plan. FCC-ee can be built with today's technology. Most of the FCC-ee infrastructure could be reused for FCC-hh. Combining concepts from past and present lepton colliders and adding a few novel elements, the FCC-ee design promises outstandingly high luminosity. This will make the FCC-ee a unique precision instrument to study the heaviest known particles (Z, W and H bosons and the top quark), offering great direct and indirect sensitivity to new physics. ; European Union [654305, 764879, 730871, 777563]; FP7 [312453] ; Open access article ; This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
