(IANDS, 2006)1present in this paper a tale from Pu Songling's "Strange Stories from Liaozhai's Studio." This story seems to contain the following key elements ofa near-death experience: the life review, travel through a spiritual world, ...
-
(2009)This study characterizes the structure of a plant-pollinator network in a temperate rain forest of Chiloé Island, southern Chile, where woody species are strongly dependent on biotic pollinators, and analyzes its robustness ...
-
(Elsevier, 2011)Many organisms exhibit ontogenetic shifts in their diet and habitat use, which often exert a large influence on the structure and expected dynamics of food webs and ecological communities. Nevertheless, reliable methods ...
-
(Human Sciences Press, 1989)The authors present a neurobiological model for near-death experiences (NDEs) in an attempt to correlate the biological and psychological domains. This model is based on temporal lobe dysfunction, hypoxia/ischemia, stress, ...
-
(IANDS, 1994-07-25)In this article we propose a scientific approach to explain the fact that some near-death experiencers (NDErs) are able to recollect and verbalize real events occurring in the environment during the experience. Our model ...
-
(1987)A new, rapid, and simple method for preparing long-chain alkyltrimethylammonium (A1TA+X-) or long-chain alkylpyridinium (A1Py+X-) salts (X- = F-, Cl-, Br-, NO3-, SO42-, PO42-, car{ballot box}ylic anions, etc.) is presented. ...
-
(Elsevier, 2020)A new approach to find exact solutions to one-dimensional quantum mechanical systems is devised. The scheme is based on the introduction of a potential function for the wavefunction, and the equation it satisfies. We recover ...
-
(2011)A new azorellane diterpenoid has been isolated and identified from the aerial parts of Azorella madreporica Clos. The structure of 1 was established by one- and two-dimensional NMR techniques. © 2011 Taylor & Francis.
-
(2012)In this paper, a new type of mathematical model to represent certain processes with impulsive dynamic behavior is introduced. The main assumption is that the next impulse time is determined by three fundamental elements: ...
-
(Elsevier, 2007)In this work, a characterization of reagent chromophere 5-(4-sulphophenylazo)-8-aminoquinoline [SPA] by IR and 1H RMN was carried out and a pKa value of 3.55 ± 0.03 was found as well. An 1:2 stoichiometry for the Cu(II)-SPA ...
-
(1998)A multiple Robertsonian fission chromosomal race of the Liolaemus monticola complex in Chile is described and is shown to be the most derived and the most complex among the Liolaemus examined thus far. The 29 karyotyped ...
-
(1997)From Mulinum crassifolium Phil, collected on the western flank in northern Chile, was isolated mulin-11,13-dien-20-oic acid and a new diterpenoid, 17-acetoxymulin-11,13-dien-20-oic acid 2. Its structure was established by ...
-
(Inst. Paleobiologii Pan, 2018)The contents of the superfamily Platanistoidea, an early-diverging lineage comprising extinct species and a single extant representative of South Asian river dolphin (Platanista gangetica), remain controversial. We describe ...
-
(Academic Press, 2014)A postcranial specimen from the lower Maastrichtian levels of the Conway Formation, Middle Waipara River, North Canterbury, New Zealand shows clear elasmosaurid affinities, based on the articular faces, with a ventral ...
-
(Blackwell Publishing Ltd, 2014)The amphibian genus Telmatobius is a diverse group of species that inhabits the Andes. This study analysed the phylogenetic relationships of 19 species described from the central Andes of Chile and Bolivia, and 12 undescribed ...
-
(2012)Here we show that the dynamic simulation of a molecular collision can give insight into new molecular species. In this way, a new stable isomer of C 20 (IV) has been found. It is planar with pentagonal form. This isomer ...
-
A new method of assessing rates of the futile cycle during glycolytic and gluconeogenic metabolism (1995)A method for assessing rates of the futile cycle is presented, and it is illustrated in vitro. Glycolytic- and gluconeogenic-type cycles are simulated for the reactions catalyzed by phosphofructokinase (EC 2.7.1.11) and ...
-
(Medknow Publications, 2014)Background: Azorella compacta is a rare yellow-green compact resinous cushion shrub growing from the high Andes of southern Peru to northwestern Argentina, and which is a producer of biologically active and unique diterpenoids. ...
-
(Copernicus Gesellschaft MBH, Germanyc, 2021)A new monotypic genus of Neogene odontocete (Isoninia borealis) is named on the basis of a partial skull (CMM-V-4061). The holotype was found on the riverbed of the Meherrin River (North Carolina, USA) and probably originated ...
-
(2012)Crepipatella occulta n. sp. is described from the intertidal zone in northern Chile. This species is morphologically cryptic with two other Crepipatella species from Chile, Crepipatella dilatata (Lamarck, 1822) and ...
