Self-Sensitized Photooxygenation of 2H-Pyrans: Characterization of Unexpected Products Assisted by Computed Structural Elucidation and Residual Dipolar Couplings
(American Chemical Society, 2015-08)
The UVA (350 nm) irradiation of an α-pyran in the presence of oxygen led to the unexpected formation of a tetraoxygenated compound whose structure could not be unambiguously determined on the basis of conventional 1H-13C ...
Metal Removal from Wastewater Using Sludge from a Natural Stabilization Pond as Biosorbent
(University of Tehran, 2019-06)
The present work was focused on evaluating the potential use of a sludge produced in a municipal natural facultative pond as biosorbent to remove metal ions (Pb2+, Cd2+, Ni2+, and Cr6+) from aqueous solutions. The influences ...
New evidence for differential roles of L10 ribosomal proteins from Arabidopsis
(American Society of Plant Biologist, 2013-09)
The ribosomal protein L10 (RPL10) is an integral component of the eukaryotic ribosome large subunit. Besides being a constituent of ribosomes and participating in protein translation, additional extra-ribosomal functions ...
À rebours: Memoria, usi del passato ed emancipazione politica

Il presente contributo si propone di esaminare alcuni aspetti del rapporto che lega uso memoriale del passato ed emancipazione politica, nella prospettiva ambivalente dell’esercizio di un dominio o di un processo di ...
Brucella abortus depends on L-serine biosynthesis for intracellular proliferation
(American Society for Microbiology, 2019-11)
L-Serine is a nonessential amino acid and a key intermediate in several relevant metabolic pathways. In bacteria, the major source of L-serine is the phosphorylated pathway, which comprises three enzymes: D-3-phosphoglycerate ...
Comparative androgenetic competence of various species and genotypes within the genus Pisum L.
(Springer, 2020-09)
In pea breeding is important to shorten the generation cycles to obtain homozygosity quickly. Doubled haploid technology is important to attain this purpose and androgenesis is the most promising tool for induction of ...
SK2 channels are required for function and long-term survival of efferent synapses on mammalian outer hair cells
(Academic Press Inc Elsevier Science, 2009-01)
Cochlear hair cells use SK2 currents to shape responses to cholinergic efferent feedback from the brain. Using SK2-/- mice, we demonstrate that, in addition to their previously defined role in modulating hair cell membrane ...
Los mestizos más puros. Representaciones chiriguano y chané del mestizaje

El punto de partida de este artículo es la tesis desarrollada en 1991 por Isabelle Combès y Thierry Saignes sobre el nacimiento de la etnia y la identidad chiriguano, mestizas ´por esencia´. La relación que mantienen ...
Shoot litter breakdown and zinc dynamics of an aquatic plant, Schoenoplectus californicus
(Taylor & Francis, 2018-07)
Decomposition of plant debris is an important process in determining the structure and function of aquatic ecosystems. The aims were to find a mathematic model fitting the decomposition process of Schoenoplectus californicus ...
