The ∼37 million-year-old Birket Qarun Locality 2 (BQ-2), in the Birket Qarun Formation of Egypt's Fayum Depression, yields evidence for a diverse primate fauna, including the earliest known lorisiforms, parapithecoid anthropoids, and Afradapis longicristatus, a large folivorous adapiform. Phylogenetic analysis has placed Afradapis as a stem strepsirrhine within a clade of caenopithecine adapifo...

FOUR KNOWN FLAVONOIDS quercetin 3-O-β-D-rutinoside (Q3Rut), myricetin 3-O-β-D-galactopyranoside (M3Gal), quercetin 3-O-β-D-galactopyranoside (Q3Gal) and quercetin 3-O-β-D-glucopyranoside (Q3Glc), for the first time were isolated from aerial parts of Euphorbia microsciadia. The chemical structure of them was elucidated on the basis of 1 and 2 D-NMR spectra and different spectroscopic techniques....

En este artículo, se estudian patrones distribución espacial endemismos la riqueza especies, análisis parsimonioso endemicidad (PAE por sus siglas inglés) interpo...

Abstract. Microclonal propagation of rare plant species solves the problem biodiversity conservation, because received explants can be introduced into natural conditions to maintain stability communities. The purpose research was obtain in vitro cultures plants from Fabaceae family: Astragalus gorodkovii and gorczakovskii. Materials methods: seeds were selected population Komi Republic 2004. Se...

We introduce a simplicial pseudo-random version of lattice gauge theory. In this formulation it is possible to interpolate continuously between a regular simplicial lattice and a pseudo-random lattice. Using this method, we study -a simple three dimensional Abelian lattice gauge theory. Calculating average plaquette expectation values, we find an extremum of the action for our regular simplicia...
