(Elsevier, 2015)Identification of vacancies in atomic structures plays a crucial role in the characterization of a material, from structural to dynamical properties. In this work we introduce a computationally improved vacancy recognition ...
-
(1995)Comparative studies of granivory intensity across different arid and semi‐and regions of the world have assumed homogeneity of conditions over large geographical areas, despite the existence of evident heterogeneities at ...
-
(MDPI, 2020)Adsorption technologies are a focus of interest for the removal of pollutants in water treatment systems. These removal methods offer several design, operation and efficiency advantages over other wastewater remediation ...
-
(1982)A study of ternary complex formation between nickel, pyridine and picrate ion has been made. The metal - pyridine complex reacts with picrate to give an insoluble, stable, green precipitate. Conditions of formation, ...
-
(Springer, 2012)Purpose Recent reports discuss the altered bone homeostasis in cigarette smokers, being a risk factor for osteoporosis and negatively influencing fracture healing. Cigarette smoke is known to induce oxidative stress in ...
-
(1987)The ground state potential energy curves of alkali (LiH to CsH) and alkaline-earth monohydrides (BeH to BaH) have been calculated. A pseudopotential formalism including a core-polarization potential has been used. For the ...
-
(Universidad Autonoma de Madrid, 2007)Consider a finite group G acting on a Riemann surface S, and the associated branched Galois cover πG : S → Y = S/G. We introduce the concept of geometric signature for the action of G, and we show that it captures much ...
-
(Springer, 2015)We describe the action of the full automorphisms group on the Fermat curve of degree N. For N prime, we obtain the group algebra decomposition of the corresponding Jacobian variety.
-
(ELSEVIER, 2006-05-10)We propose and test an empirical nucleofugality index to rank the leaving group ability of a series of molecular fragments present in nucleophilic substitution reactions of carbonyl and thiocarbonyl derivatives. The ...
-
(Taylor & Francis, 2015)The main goal of this study was to find bacterial isolates with the ability to inhibit the growth of the fish pathogens Aeromonas hydrophila, Vibrio anguillarum, and Flavobacterium psychrophilum and to inhibit the blockage ...
-
(BIRKHAUSER VERLAG AG, 2008-09)We prove that, for all α > 0, every finitely generated group of C1+α diffeomorphisms of the interval with sub-exponential growth is almost nilpotent. Consequently, there is no group of C1+α interval diffeomorphisms having ...
-
(The Royal Society of Chemistry, 2018-06-28)We studied the soft landing of Ni atoms on a previously damaged graphene sheet by means of molecular dynamics simulations. We found a monotonic decrease of the cluster frequency as a function of its size, but few big ...
-
(1997)Seedlings of nine southern Chilean trees were grown at three nutrient supply rates, to examine the roles of growth rate, biomass distribution and nutrient use traits in determining species natural distributions on resource ...
-
(1991)The investigation of three Stevia species afforded a large variety of known sesquiterpene lactones as well as one new guaianolide, two known longipinene derivatives, two ent-labdanes and several other common compounds. © 1991.

-
(Wiley, 2021)There has been much recent interest in the concept of rewilding as a tool for nature conservation, but also confusion over the idea, which has limited its utility.We developed a unifying definition and 10 guiding principles ...
-
(Finnish Zoological and Botanical Publishing Board, 2009)To date, digestive flexibility has been studied in dozens of vertebrate species. However, practically all of these works has ignored the importance of intraspecific physiological variability across populations inhabiting ...
-
(2016)We report an experimental study on the effect of solvents on the model SNAr reaction between 1-chloro-2,4dinitrobenzene and morpholine in a series of pure ionic liquids (IL). A significant catalytic effect is observed with ...
-
(Frontiers Media, 2022)An experimental and computational methodology for the analysis of the Lewis acid/base responses of ionic liquids (ILs) and deep eutectic solvents (DES) is proposed. It is based on the donor and acceptor of the electronic ...
