In this work, we present the galaxy clustering measurements of the two DES lens galaxy samples: a magnitude-limited sample optimized for the measurement of cosmological parameters, maglim , and a sample of luminous red galaxies selected with the redmagic algorithm. maglim / redmagic sample contains over 10 million/2.5 million galaxies and is divided into six/five photometric redshift bins spanning the range z ∈ [0.20, 1.05]/ z ∈ [0.15, 0.90]. Both samples cover 4143 |$\deg ^2$| over which we perform our analysis blind, measuring the angular correlation function with an S/N ∼ 63 for both samples. In a companion paper, these measurements of galaxy clustering are combined with the correlation functions of cosmic shear and galaxy–galaxy lensing of each sample to place cosmological constraints with a 3 × 2pt analysis. We conduct a thorough study of the mitigation of systematic effects caused by the spatially varying survey properties and we correct the measurements to remove artificial clustering signals. We employ several decontamination methods with different configurations to ensure the robustness of our corrections and to determine the systematic uncertainty that needs to be considered for the final cosmology analyses. We validate our fiducial methodology using lognormal mocks, showing that our decontamination procedure induces biases no greater than 0.5 σ in the (Ωm, b) plane, where b is the galaxy bias.

Viguiera dentata (Cav.) Sprenguel (Asteraceae) is known as “chimalacate” in several Mexican states. Infusions of the aerial part of this species are used for the treatment of baby rash by the inhabitants of San Rafael, Coxcatlan, Puebla, Mexico. We examined the antibacterial and antifungal activities through the disk-diffusion method. The composition and antimicrobial activity of the essential oil of V. dentata is reported here for the first time. The essential oil of aerial parts of V. dentata was examined by GC-MS: it is constituted mainly by monoterpenes (57.16%), and of this the major components are 1,3,3-trimethyl-tricyclo[2.2.1.02,6] heptane (30.85%) and limonene (13.27%). Gram-positive and Gram-negative bacteria were sensitive to the essential oil. The essential oil had no antifungal activity. The hexane extract H1 presented antibacterial activity against seven strains (four Gram-positive and three Gram-negative); this extract had no antifungal activity. One bioactive compound, ent-kaur-16-en-19-oic acid 1, was isolated. In comparison with the essential oil and H1, the pure compound 1 showed the lowest MICs in the majority of the bacterial strains. Only the hexane partition (H2) of the methanol extract showed antifungal activity against all tested fungi. [ABSTRACT FROM AUTHOR]

Depending on the biomass yield on glucose and the cell morphology of Bacillus thuringiensis, three different metabolic states were observed in continuous culture. At dilution rates between 0.18 h and 0.31 h vegetative cells, sporulating bacteria and spores coexisted, while glucose and amino acids were consumed. Only vegetative cells were observed at dilution rates between 0.42 h and 0.47 h and glucose was used as the main carbon and energy source. At D = 0.50 h the biomass yield on glucose decreases sharply. To define better the specific growth rate range in which the microorganism uses mainly glucose, a dilution rate of 0.25-0.45 h was studied. The experimental data could be adjusted to a Monod model and the following rate coefficients and growth yields were determined: maximum specific growth rate 0.54 h, saturation constant 0.56 mg glucose ml, biomass growth yields 0.43 g cells (g glucose), and 0.76 g cells (g oxygen), and maintenance coefficients 0.065 g glucose (g cells) h and 0.039 g oxygen (g cells) h.
