(Elsevier B.V., 2019)Landscape composition and heterogeneity are considered important factors for enhancing biodiversity and their associated ecosystem services in human-modified landscapes. Despite their roles in pest suppression in agricultural ...
-
(International Union against Tubercul. and Lung Dis., 2019)BACKGROUND: Tuberculosis (TB) diagnosis in human immunodeficiency virus (HIV) positive persons is difficult, particularly in resource-limited settings. The relationship between TB culture status and mortality in HIV-positive ...
-
(Universidad CES, 2019)This paper aims to make a discourse analysis of the processes that reverse memories of the Colombian conflict in national newspapers. The research adopts a theoretical approach that describes reversed memory as a narratological ...
-
(American Society for Enology and Viticulture, 2019)Crimson Seedless is one of the most important table grape cultivars in the world, but often exhibits uneven berry color when grown in warm climates. Deficit irrigation is used extensively by growers during the ripening ...
-
(Elsevier B.V., 2019)The intensive management of tree plantations has replaced and fragmented native forests worldwide. A direct consequence of this activity is the creation of new edges, which generate changes in microclimatic conditions in ...
-
(Public Library of Science, 2019)Human presence at intertidal areas could impact coastal biodiversity, including migratory waterbird species and the ecosystem services they provide. Assessing this impact is therefore essential to develop management measures ...
-
(Elsevier B.V., 2019)The “blooming desert”, or the explosive development and flowering of ephemeral herbaceous and some woody desert species during years with abnormally high accumulated rainfall, is a spectacular biological phenomenon of the ...
-
(American Chemical Society, 2019)Polycyclic aromatic compounds (PACs) can have multiple sources in the Athabasca Oil Sands Region (AOSR). The current study was designed to identify and explore the potential of nitrogen heterocyclic PACs (NPACs) as source ...
-
(Public Library of Science, 2019)Mesenchymal stem cells (MSCs) can trans/differentiate to neural precursors and/or mature neurons and promote neuroprotection and neurogenesis. The above could greatly benefit neurodegenerative disorders as well as in the ...
-
(Society for Industrial and Applied Mathematics Publications, 2019)In this paper we establish that the set of Lipschitz functions f : U → R (U a nonempty open subset of ` 1 d ) with maximal Clarke subdifferential contains a linear subspace of uncountable dimension (in particular, an ...
-
(Nature Publishing Group, 2019)We performed an integrated analysis of the coseismic slip, afterslip and aftershock activity of the 2014 M w 8.1 Pisagua earthquake. This earthquake seems to be spatially located between two major historical earthquakes, ...
-
(Elsevier B.V., 2019)Long-standing literature argues that social capital is closely implicated in labour market outcomes. However, this hypothesis has yet to be tested in Latin America, the most unequal region in the world. We focus on Chile, ...
-
(Elsevier B.V., 2019)The principles governing surfactant-lipid interactions, involved in biological membrane solubilization and reconstitution processes, are a topic of great interest in the field of membrane biochemistry and biophysics. Among ...
-
(Elsevier B.V., 2019)Frosts are one of the most harmful weather events, causing recurrent and great damage in agriculture. Active control methods, such as wind machines, must be implemented to reduce the impact on crops. A new portable wind ...
-
(Blackwell Publishing Ltd, 2019)We calculate well-resolved corner frequencies and radiated energies for a set of 96 earthquakes divided into two clusters located in the same tectonic setting but with different depths in northern Chile. Fifty-three shallow ...
-
(Academic Press Inc., 2019)In the paper ‘A probabilistic analysis of a discrete-time evolution in recombination’ [4] the evolution of the recombination transformation Ξ=∑δρδ⨂J∈δμJ was described by a Markov chain (Yn) on a set of partitions, which ...
-
(Hindawi Limited, 2019)Recent studies have detected different antimicrobial residues in broiler chicken feathers, where they persisted for longer periods of time and at greater concentrations than in edible tissues. However, until today, lincomycin ...
-
(Springer Science and Business Media Deutschland GmbH, 2019)Natural populations of the house mouse Mus musculus domesticus show great diversity in chromosomal number due to the presence of chromosomal rearrangements, mainly Robertsonian translocations. Breeding between two populations ...
-
(Springer New York LLC, 2019)We consider the problem of finding positive solutions of the problem Δu − λu + u 5 = 0 in a bounded, smooth domain Ω in ℝ 3 , under zero Neumann boundary conditions. Here λ is a positive number. We analyze the role of ...
-
(Wiley Blackwell, 2019)Odor transduction in the cilia of olfactory sensory neurons involves several ATP-requiring enzymes. ATP is generated by glycolysis in the ciliary lumen, using glucose incorporated from surrounding mucus, and by oxidative ...
