(2007)• The SERRATE gene (SE) was shown to determine leaf organogenesis and morphogenesis patterning in Arabidopsis thaliana. The se-1 mutant was used here to investigate the role of SE in leaf development in response to incident ...
-
(1988)The apparent permeation rate constants and amount of ranitidine transferred in 1 h were measured through everted rat intestine using a perfusion apparatus. The effects of pH and 5% or 10% ethanol on the apparent permeation ...
-
(1994)Infrared spectra in the region 4000-70 cm-1 are recorded for [1,2-bis(diphenylphosphino)methane](triphenylphosphite)bromo (cis,cis- and trans-dicarbonyl)manganese, and η5-cyclopentadienyl-[1,2-bis(diphenylphosphino)ethan ...
-
(2008)The genus Robsonella Adam, 1938 belongs to the family Octopodidae and can only be identified by some characters present in males. In this work the species Robsonella fontaniana is redescribed from morphological and ...
-
(1992)The solubility behavior in water of different salts of cetyltrimethyl ammonium (CTA+), such as iodide (CTAI), thiocyanate (CTASCN), and perchlorate (CTAClO4), is reported. The order of solubilities is CTASCN > CTAI > ...
-
(Sociedad Chilena de Quimica, 2007)This paper describes the electrochemical reduction of nitrite ion in basic media 0.2M KHC03, with glassy carbon or ITO electrodes modified with a conducting polymer derived from Co(II)tetra-3-aminophenyl-porphyrin. Cyclic ...

Mitochondrial DNA variation and systematics of the guanaco (Lama guanicoe, Artiodactyla: Camelidae) (2008)Guanacos (Lama guanicoe) are the most important native herbivorous species in the South American steppes and the dominant ungulate in a fauna rich in rodents but poor in large mammal species. Between 2 and 4 subspecies are ...
-
(1990)The relative thermodynamic stabilities of several ion-pair structures, including intimate and solvent-separated forms, in solution have been studied for the allyl+/F- and allyl-/Li+ model systems. The electrostatic part ...
-
(1990)The exposure of drugs to light produces photodecomposition processes in several cases: the drugs undergo important chemical changes with a parallel change in their activities or potencies and generally with a loss of their ...
-
(1992)Infrared spectra of solids Cp*Re(CO)2[PO(OMe)2]X, where Cp* = η5-C5Me5 and X = Cl, Br and I, were recorded. An assignment is offered in which the normal modes are described in terms of "local symmetry". This assignment is ...
-
(1990)The reactions of N,N′-thiobismorpholine, {A figure is presented}, with Fe(CO)5, Fe2(CO)9, Fe3(CO)11 and [(η5-C5H5)Fe(CO)2THF]BF4 were examined. Thiobismorpholine undergoes desulphurization towards Fe(CO)5 with formation ...
-
(Elsevier, 1997)We perform a fully quantum mechanical numerical calculation for the problem of a single electron (or excitation) propagating in an N-site one-dimensional chain in the presence of a single Holstein impurity. We compute the ...
-
(2008)The Xylocopinae contains four tribes with species which show a range of nesting habits, from solitary to social. The Manueliini is the sister group to all other Xylocopine tribes, with one genus, Manuelia, of three species ...
-
(American Chemical Society, 1987)New cationic high-spin iron(II) complexes with substituted thioureas and with perchlorate or tetrafluoroborate anions (X) were obtained: [FeL6]X2(L = N-ethylthiourea, N,N’-di-n-propylthiourea); [FeLn](ClO4)2(L = ...
-
(1990)The effects of gramine on the bacterium Pseudomonas syringae in culture and on barley leaf disks were studied. Gramine prolonged the lag phase of growth and decreased the size of the population at stationary phase at ...
-
(2004)An effective method for controlling nonlinear switching of discrete solitons in arrays of weakly coupled optical waveguides was discussed. The key ideas of the array engineering by means of a steplike variation of the ...
-
(2007)The cytoskeleton and cytoskeletal motors play a fundamental role in neurotransmitter receptor trafficking, but proteins that link GABAB receptors (GABABRs) to the cytoskeleton have not been described. We recently identified ...
-
(2007)In this study we hypothesized that Grammostola rosea Walckenaer 1837, an active predator of large size that depends on its two paired book lungs for respiration, would have a refined low energy strategy based on its thin ...
-
(1999)We use the Green’s-function formalism for an exact, numerical calculation of the stationary states of an electron propagating in a square lattice in the presence of a single, Holstein-type, impurity of arbitrary nonlinearity ...
-
(1995)The representation of the electronic structure of intercalated 1T - TiS2 with lithium by a cluster approximation is discussed. The electronic chemical potential, defined in the context of density functional theory, is used ...
