1-Octanol-water partition coefficient of some cyanopyridine and chalcone compounds
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Farmacia, 2017-09-01)
The partition coefficients (P) of some synthesized cyanopyridine and chalcone compounds have been studied in 1-octanol-water system at different pH. It is observed that log P depends on pH and nature of substitution group ...
Growth and biomass partitioning of nine provenances of Quillaja saponaria seedlings to water stress
(NISC Pty Ltd, 2019)
© 2018, © 2018 NISC (Pty) Ltd.Information on the morphological and physiological responses of seedlings to stressors, such as water stress, is required for successful early establishment of seedlings. We examined provenance ...
Seasonal, spatial and diel partitioning of Acyrthosiphon pisum (Hemiptera: Aphididae) predators and predation in alfalfa fields
(Elsevier, 2014)
Predators are important natural enemies, often responsible for preventing pest population outbreaks of in
many crops. Complementarity in resource use involves spatial or temporal segregation of predators,
which can result ...
Nucleotide second messenger-based signaling in extreme acidophiles of the Acidithiobacillus species complex: Partition between the core and variable gene complements
(Frontiers Media, 2019)
Cyclic and linear nucleotides are key elements of the signal transduction networks linking perception of the environment to specific cellular behavior of prokaryotes. These molecular mechanisms are particularly important ...
Wind waves climatology of the Southeast Pacific Ocean
(Wiley, 2017)
The climatology of wind waves over the Southeast Pacific is analysed using a 32-year hindcast from the WaveWatch III model, complemented by satellite-derived significant wave height (SWH) and buoy measurements for validation. ...
Variations in efficiencies of triplet state and exciplex formation following fluorescence quenching of 9,10-dicyanoanthracene due to charge transfer interactions
(2003)
Data is presented on the quenching of 9,10-dicyanoanthracene by benzene derivatives in acetonitrile. The quenching occurs via a charge transfer mechanism with the quenching rate constants exhibiting a Rehm-Weller dependence ...
Topology of Plant - Flower-Visitor Networks in a Tropical Mountain Forest: Insights on the Role of Altitudinal and Temporal Variation
(Public Library of Science, 2015)
Understanding the factors determining the spatial and temporal variation of ecological networks is fundamental to the knowledge of their dynamics and functioning. In this study, we evaluate the effect of elevation and time ...
Ecological and biogeographical inferences on two sympatric and enigmatic Andean cat species using genetic identification of faecal samples
(2008)
The carnivore community of the altiplano ecosystem of the high Andes, including the Andean mountain cat (Leopardus jacobita) and pampas cat (Leopardus colocolo), is one of the least studied in the world. We determined the ...
Intraspecific variation in drought response of three populations of Cryptocarya alba and Persea lingue, two native species from mediterranean Central Chile
(Frontiers, 2020)
An increase in the severity of drought events on Mediterranean climates highlights the need of using plant material adapted to drought during restoration efforts. Thus, we investigated between-population morpho-physiological ...
Skeletodental diagnosis using a geometric morphometric aproach
(2014)
In orthodontics and maxillofacial surgery, dentoeskeletal diagnosis is essential for treatment planning.
Traditionally, this diagnosis is carried out using cephalometric analysis based on the comparison of distances and ...
