Monitoring of emerging water stress situations by thermal and vegetation indices in different almond cultivars

In recent years, the area dedicated to modern irrigated almond plantations has increased significantly in Spain. However, the legal irrigation allocations are lower than the maximum water requirements of the crop in most cases. Therefore, almond growers are forced to implement regulated deficit irrigation strategies on their farms, applying water stress in certain resistant phenological periods and avoiding it in sensitive periods. Given the need to monitor the water status of the crop, especially in the most sensitive periods to water stress, the objective of this work was to evaluate the sensitivity of two UAV-based crop water status indicators to detect early water stress conditions in four almond cultivars. The field trial was conducted during 2020 in an experimental almond orchard, where two irrigation strategies were established: full irrigation (FI), which received 100% of irrigation requirements (IR), and regulated deficit irrigation (RDI), which received 70% of IR during the whole irrigation period except during the kernel-filling stage when received 40% IR. The UAV flights were performed on four selected dates of the irrigation season. The Crop Water Status Index (CWSI) and the Normalized Difference Vegetation Index (NDVI) were derived from thermal and multispectral images, respectively, and compared to classical water status indicators, i.e., stem water potential (Ψstem ), stomatal conductance (gs ), and photosynthetic rate (AN ). Of the four flights performed, three corresponded to mild water stress conditions and a single flight was performed under moderate water stress conditions. Under mild water stress, CWSI was not able to capture the differences between FI and RDI trees that were observed with Ψstem . Under moderate stress conditions, CWSI was sensitive to the water deficit reached in the trees and showed significant differences among both irrigation treatments. No differences were observed in the CWSI and NVDI response to water stress among cultivars. Although NDVI and CWSI were sensitive to water stress, the low signal intensity observed in NDVI makes this index less robust than CWSI to monitor crop water stress. It can be concluded that UAV-based CWSI measurements are reliable to monitor almond water status, although for early (mild) levels of water stress, Ψstem seems to be the preferred option.Junta de Andalucía AVA.AVA2019.05

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Punto de fuga. Punto de encuentro : aproximación interdisciplinar a las Vanguardias Artísticas de la segunda mitad del siglo XX

Resumen basado en el del proyecto. Premiado en la convocatoria: Premios para proyectos de innovación concluidos durante el curso 2007-2008, en los centros educativos no universitarios sostenidos con fondos públicos de la Comunidad Autónoma de Castilla-La Mancha (Orden 12-12-2008, de la Consejería de Educación y Ciencia de la Junta de Comunidades de Castilla-La Mancha. Resolución de 5-5-2009, de la Viceconsejería de Educación)El proyecto se desarrolla entre cinco centros: la Escuela de Arte de Guadalajarara, la Escuela de Hostelería y Turismo del IES Antonio Buero Vallejo de Guadalajara, el Conservatorio Provincial de Música de Guadalajara, el IES Profesor Domínguez Ortiz de Azuqueca de Henares y el Colegio Infantil y Primaria Castillo de Pioz. La idea central es la de abordar de forma interdisciplinar un tema común entre centros de distinta naturaleza armonizando el calendario de realización. Se buscan elementos integradores que permitan que el alumno se involucre activamente en un aprendizaje significativo con uno de los elementos clave en la educación, la motivación. Los objetivos son: fomentar la idea de que todas las áreas de conocimiento y creación humanas son producto de épocas y situaciones concretas englobadas en un todo; fomentar la participación activa en el proceso educativo; descubrir que el arte es algo vivo y que puede formar parte de la propia personalidad; fomentar el espíritu colectivo, la relevancia en el cumplimiento de los plazos y la valoración de la mirada del espectador sobre lo realizado; descubrir nuevos modos de comunicación y de relación; promover la reflexión anti-racista, anti-sexista, pacifista y solidaria. El tema elegido, la segunda mitad del siglo XX, especialmente las décadas de los 50, 60 y 70. Años de grandes transformaciones sociales y económicas en Europa. Su aproximación es multidisciplinar, desde la música, las artes plásticas, la literatura, la gastronomía, y el desarrollo del turismo como una industria potente que contribuirá además económicamente a sacar del ostracismo al pais.Castilla La ManchaConsejería de Educación, Ciencia y Cultura.

Measurement of the total and differential inclusive B+\mathrm{B^+} hadron cross sections in pp collisions at s=13\mathrm{\sqrt{s} = 13} TeV

The total and differential cross sections for inclusive production of $B^+$ hadrons are measured as a function of the $B^+$ transverse momentum $p_{T}^{B}$ and rapidity $y^{B}$ in pp collisions at a centre-of-mass energy of 13 TeV, using data collected by the CMS experiment that correspond to an integrated luminosity of 49.4 inverse-picobarns. The measurement uses the exclusive decay channel $B^+ \to J/\psi K^+$, with $J/\psi$ mesons that decay to a pair of muons. The results show a reasonable agreement with theoretical calculations within the uncertainties

Studies of inclusive four-jet production with two bb-tagged jets in proton-proton collisions at 7 TeV

Measurements are presented of the cross section for the production of at least four jets, of which at least two originate from b quarks, in proton-proton collisions. Data collected with the CMS detector at the LHC at a center-of-mass energy of 7 TeV are used, corresponding to an integrated luminosity of 3 pb$^{-1}$. The cross section is measured as a function of the jet transverse momentum for p$_T$>20 GeV, and of the jet pseudorapidity for |η|<2.4 (b jets), 4.7 (untagged jets). The correlations in azimuthal angle and pT between the jets are also studied. The inclusive cross section is measured to be σ(pp→2b+2j+X)=69±3(stat)±24(syst) nb. The η and p$_T$ distributions of the four jets and the correlations between them are well reproduced by event generators that combine perturbative QCD calculations at next-to-leading-order accuracy with contributions from parton showers and multiparton interactions
