(1972)Changes in the fatty acid composition of egg‐yolk fat of hens fed diets with increasing fish meal content are studied by total fatty acid analysis. The fatty acid composition of the major lipid fractions in egg‐yolk fat ...

(Universidad Técnica del Estado, 1972-07)Se describe el uso de brebajes preparados con tallos de Banisteriopsis y hojas de Psychotria por la tribu de los Shipibos y en la ciudad de [quitos. El análisis de una muestra de la especie de Banisteriopsis usada, ...
-
(Elsevier, 1972-08-14)A sample of a plant growing near Longotoma, Aconcagua, identified as Solanum pinnatum Cavo (Voucher specimen No. BClO deposited in the herbarium of the Museo Nacional de Historia Natural, Santiago), wás examined for ...
-
(1973)The models for electronic phase transitions of Ce1-xLax alloys are critically examined. The ideas put forward in the preceding paper are shown to be inconsistent and to lead to unphysical results. Finally, an experimental ...
-
(1973)We have investigated the susceptibility of the Mattis Hamiltonian by means of Green's-function techniques and using a functional-integral formulation. It turns out that it is not possible to obtain an exact solution for ...
-
(1973)Energy gaps near the Fermi surface arising from magnetic Brillouin zone effects must be taken into account in order to understand the antiferromagnetism of europium metal. © 1973 Pergamon Press.
-
(1973)Water soluble enzymes obtained from orange flavedo form two isomeric farnesols from 1-3H labeled geranylpyrophosphate plus isopentenylpyrophosphate. © 1973.
-
(1973)A continuous two‐hour water extraction procedure is proposed instead of the former 14‐hour method to remove the thioglucosides from rapeseed presscake meal (RSM). This new procedure produced a complete removal of isothiocyanates ...
-
(1973)Cell kinetics parameters were obtained for the three mitotic divisions leading to formation of stomata in the epidermis of the cotyledon of Allium cepa seedlings. Analysis of mitotic frequencies throughout the course of ...

-
(1974)The effects due to localized spin fluctuations (LSF) in dilute superconducting alloys are investigated. Expressions for the critical temperature Tc as function of impurity concentration nI and the specific heat jump at the ...
-
(1974)The effects of localized spin fluctuations on the critical temperature Tc and the specific-heat jump Δ C (Tc) of dilute superconducting alloys is investigated, both in the weak and strong magnetic limits. In the weak ...
-
(1974)The inversion of Rayleigh wave dispersion data for the Pacific Ocean shows that lithospheric thickness increases systematically with age. The lid to the low-velocity channel is very thin or absent near the ridge crest; the ...
-
(Universidad de Santiago de Chile, Direccion de Planificacion y Desarrollo II, 1974)De hojas y tallos de Solanum tomatillo recolectado en diciembre de 1971 en los faldeos del cerro Lo Curro (Santiago), fue aislada una sapogenina esteroidal caracterizada como diosgenina, con un rendimiento de O,002rPlo. ...
-
(1974)A calorimetric investigation of the magnetic-nonmagnetic transition of an impurity (Ce) in a superconducting binary-alloy matrix (La, Th) is reported for the first time. The continuous demagnetization of the Ce ions with ...
-
(1974)The first ten potassium-argon determinations made on andesitic rocks of the Andes and Coastal ranges of central-south Chile, between latitudes 36° and 42° South, demonstrate the existence of at least two main cycles of ...
