Opis:
In the High Valleys of Mexico maize is produced with varied yield and quality which sometimes do not meet the parameters established by maize flour milling and nixtamalization industry for making tortilla. Therefore, an evaluation of the yields and quality of the grain of maize hybrids (Zea mays L.) and their relationship with the environment was performed. During the spring-summer cycle 2012, the hybrids HP-1, H-52, H-68, HP-2, H-70, Buho, HP-3, H-57E, H-64, Prospecto-1, H-72 and H-66 were evaluated in Texoloc and Benito Juárez (2240 and 2530 masl), Tlaxcala, Mexico in a design of completely randomised blocks with three replications. Grain yield (GY), thousand grain weight (TGW), hectolitric weight (HW), width (WG), length (LG) and thickness (TG) of grains were measured. The results showed highly significant differences (p = 0.01) between locations, hybrids and the interaction locality x hybrids for physical parameters. Among the localities, Texoloc had 86.59% and 24.32% higher GY and TGW compared to Benito Juarez, respectively, while the HW was slightly lower (73.68 kg hL-1). Average yields of the hybrids were 7.7 t ha-1; HP-2, HP-3, H-57E and H-66 hybrids had yields of more than 8 t ha-1 and the lowest yield was noted for H-70. The hybrids had an average HW of 74.30 kg hL-1; HP-1, H-68, H-70, Buho, HP-3 and H-72 had values > 74 kg hL-1, complying with the provisions of the quality standard NMX-FF034/1-SCFI- 2002 for maize destined for the nixtamalization process. The variation in agroclimatic conditions between the localities affected the yield and physical quality of maize grain.
W Wysokich Dolinach Meksyku produkowana jest kukurydza o zróżnicowanej jakości i poziomie plonowania, która nie zawsze spełnia wymagania przemysłu młynarskiego i nixtamalizacji mąki kukurydzianej do produkcji tortilli. Z tego powodu przeprowadzono badania, mające na celu ocenę plonowania i jakości ziarna hybryd kukurydzy (Zea mays L.) oraz ich zależności od warunków środowiskowych. W sezonie wiosenno-letnim roku 2012 przeprowadzono badania na hybrydach HP-1, H-52, H-68, HP-2, H-70, Buho, HP-3, H-57E, H-64, Prospecto-1, H-72 oraz H-66 w Texoloc i Benito Juárez (2240 i 2530 m n.p.m.), Tlaxcala w Meksyku. Badania przeprowadzono w systemie bloków losowych, w trzech powtórzeniach, dokonując pomiarów plonu ziarna, masy tysiąca ziaren, masy hektolitra ziarna oraz szerokości, długości i grubości ziarna. Stwierdzono istotne różnice (p = 0,01) pomiędzy lokalizacjami, hybrydami oraz interakcjami lokalizacja- hybryda w zakresie parametrów fizycznych ziarna. Wartości plonu i masy 1000 ziaren w Texoloc były wyższe odpowiednio o 86,59% i 24,32% w porównaniu do wartości otrzymanych w Benito Juarez, podczas gdy wartość masa hektolitra była nieznaczenie niższa (73,68 kg·hL-1). Średni plon ziarna hybryd wyniósł 7,7 t·ha-1; plony hybryd HP-2, HP-3, H-57E i H-66 były powyżej 8 t·ha-1, a najniższy plon uzyskano dla hybrydy H-70. Średnia wartość masy hektolitra dla hybryd kukurydzy wyniosła 74,30 kg·hL-1; dla hybryd HP-1, H-68, H-70, Buho, HP-3 i H-72 były > 74 kg·hL-1, spełniając wymagania jakościowe normy NMX-FF034/1-SCFI-2002 dla kukurydzy przeznaczonej do procesu nixtamalizacji. Zróżnicowanie warunków agroklimatycznych pomiędzy badanymi lokalizacjami miało wpływ na plonowanie i charakterystyki fizyczne ziarna kukurydzy.

Opis:
In maize plant breeding aimed at producing a hybrid, it is necessary to characterize the parents and hybrids by their agronomic aspects and grain quality so that the processing industry may offer consumers a quality product and also improve its efficiency. This study evaluated the viscoelastic parameters of masa and the chemical and texture properties of tortillas obtained from parent lines (M-54, M55, and CML-242), two single crosses (M54xM55 and M55xM54), and one hybrid (H-70). The morpho- logy of the maize grains and tortillas was analyzed using scanning electron microscopy. The firmness of masa obtained from CML-242 and H-70 maize was higher than that from the other maize genotypes. M-54 tortillas showed the lowest crude fiber content. Otherwise, tortillas obtained from the M55xM54 hard grain had the lowest fat content and extensibility, while H-70 tortillas showed an intermediate breaking point and extensibility. M-54 and M54xM55 tortillas were softer due to their more swollen starch granules. In contrast, rigid tortillas were obtained from CML-242 and H-70. Grain hardness causes different morphology in starch and tortilla of maize genotypes. However, grain hardness did not influence the characteristics of texture in tortillas.

Aims. Amongst more than fifty blazars detected in very high energy (VHE, E> 100 GeV) γ rays, only three belong to the subclass of flat spectrum radio quasars (FSRQs). The detection of FSRQs in the VHE range is challenging, mainly because of their soft spectra in the GeV-TeV regime. MAGIC observed PKS 1510−089 (z = 0.36) starting 2012 February 3 until April 3 during a high activity state in the high energy (HE, E> 100 MeV) $\gamma$-ray band observed by AGILE and Fermi. MAGIC observations result in the detection of a source with significance of 6.0 standard deviations (σ). We study the multi-frequency behaviour of the source at the epoch of MAGIC observation, collecting quasi-simultaneous data at radio and optical (GASP-WEBT and F-Gamma collaborations, REM, Steward, Perkins, Liverpool, OVRO, and VLBA telescopes), X-ray (Swift satellite), and HE $\gamma$-ray frequencies. Methods. We study the VHE $\gamma$-ray emission, together with the multi-frequency light curves, 43 GHz radio maps, and spectral energy distribution (SED) of the source. The quasi-simultaneous multi-frequency SED from the millimetre radio band to VHE γ rays is modelled with a one-zone inverse Compton model. We study two different origins of the seed photons for the inverse Compton scattering, namely the infrared torus and a slow sheath surrounding the jet around the Very Long Baseline Array (VLBA) core. Results. We find that the VHE $\gamma$-ray emission detected from PKS 1510−089 in 2012 February-April agrees with the previous VHE observations of the source from 2009 March-April. We find no statistically significant variability during the MAGIC observations on daily, weekly, or monthly time scales, while the other two known VHE FSRQs (3C 279 and PKS 1222+216) have shown daily scale to sub-hour variability. The $\gamma$-ray SED combining AGILE, Fermi and MAGIC data joins smoothly and shows no hint of a break. The multi-frequency light curves suggest a common origin for the millimetre radio and HE $\gamma$-ray emission, and the HE $\gamma$-ray flaring starts when the new component is ejected from the 43 GHz VLBA core and the studied SED models fit the data well. However, the fast HE $\gamma$-ray variability requires that within the modelled large emitting region, more compact regions must exist. We suggest that these observed signatures would be most naturally explained by a turbulent plasma flowing at a relativistic speed down the jet and crossing a standing conical shock.

We review the present status of the Standard Model calculation of the anomalous magnetic moment of the muon. This is performed in a perturbative expansion in the fine-structure constant $\alpha$ and is broken down into pure QED, electroweak, and hadronic contributions. The pure QED contribution is by far the largest and has been evaluated up to and including $\mathcal{O}(\alpha^{5})$ with negligible numerical uncertainty. The electroweak contribution is suppressed by $(m_{\mu}/M_{W})^{2}$ and only shows up at the level of the seventh significant digit. It has been evaluated up to two loops and is known to better than one percent. Hadronic contributions are the most difficult to calculate and are responsible for almost all of the theoretical uncertainty. The leading hadronic contribution appears at $\mathcal{O}(\alpha^{2})$ and is due to hadronic vacuum polarization, whereas at $\mathcal{O}(\alpha^{3})$ the hadronic light-by-light scattering contribution appears. Given the low characteristic scale of this observable, these contributions have to be calculated with nonperturbative methods, in particular, dispersion relations and the lattice approach to QCD. The largest part of this review is dedicated to a detailed account of recent efforts to improve the calculation of these two contributions with either a data-driven, dispersive approach, or a first-principle, lattice-QCD approach. The final result reads $a_{\mu}^{SM}= 116 591 810(43) \times 10^{-11}$ and is smaller than the Brookhaven measurement by 3.7 $\sigma$ The experimental uncertainty will soon be reduced by up to a factor four by the new experiment currently running at Fermilab, and also by the future J-PARC experiment. This and the prospects to further reduce the theoretical uncertainty in the near future – which are also discussed here – make this quantity one of the most promising places to look for evidence of new physics.

Opis:
This paper argues that public opinion is a useful tool and valuable source of information to better understand Latin Americans’ preferences, levels of priority and assessment of other countries, regions and institutions, including European countries, Europe, and the European Union (EU). The central arguments are, on the one hand, that the higher the levels of trade with Europe as a percentage of the total trade of Latin American countries, the higher the degree of importance, interest, and priority that Latin Americans will give to Europe, European countries, and the EU. On the other hand, the more knowledge Latin Americans have about international organisations, including the EU, the more they appreciate their work. Using the data from The Americas and the World survey, Latinobarómetro and the Map of Interests between the European Union & Latin America and the Caribbean, sufficient evidence is provided to support these arguments. If public opinion determines, to some extent, foreign policy decision making, priorities and actions, then a higher assessment and prioritisation of Europe and the EU within Latin America’s populations can have a positive effect on Latin American foreign policy vis-à-vis the EU and the countries that compose it. Therefore, increasing knowledge about and more trade with each other is a good strategy for European and Latin American countries to build on their bi-regional and bilateral relations, creating a virtuous circle of incremental cooperation and welfare for both regions.

Opis:
The discovery of rapidly variable Very High Energy (VHE; E > 100 GeV) gamma-ray emission from 4C +21.35 (PKS  1222+216) by MAGIC on 2010 June 17, triggered by the high activity detected by the Fermi Large Area Telescope (LAT) in high energy (HE; E > 100 MeV) gamma-rays, poses intriguing questions on the location of the gamma-ray emitting region in this flat spectrum radio quasar. We present multifrequency data of 4C +21.35 collected from centimeter to VHE during 2010 to investigate the properties of this source and discuss a possible emission model. The first hint of detection at VHE was observed by MAGIC on 2010 May 3, soon after a gamma-ray flare detected by Fermi-LAT that peaked on April 29. The same emission mechanism may therefore be responsible for both the HE and VHE emission during the 2010 flaring episodes. Two optical peaks were detected on 2010 April 20 and June 30, close in time but not simultaneous with the two gamma-ray peaks, while no clear connection was observed between the X-ray and gamma-ray emission. An increasing flux density was observed in radio and mm bands from the beginning of 2009, in accordance with the increasing gamma-ray activity observed by Fermi-LAT, and peaking on 2011 January 27 in the mm regime (230 GHz). We model the spectral energy distributions (SEDs) of 4C +21.35 for the two periods of the VHE detection and a quiescent state, using a one-zone model with the emission coming from a very compact region outside the broad line region. The three SEDs can be fit with a combination of synchrotron self-Compton and external Compton emission of seed photons from a dust torus, changing only the electron distribution parameters between the epochs. The fit of the optical/UV part of the spectrum for 2010 April 29 seems to favor an inner disk radius of < six gravitational radii, as one would expect from a prograde-rotating Kerr black hole.
