Razas autóctonas de las islas canarias: pasado, presente y futuro

We describe the means developed by official and private institutions for the conservation of Canary Breeds. We evaluate the response to concrete actions comparing the evolution of their census with presented at the Warwick Conference (1989).Se describen la evolución de las Razas autóctonas canarias y las medidas que se han de tomar de cara al futuro, tanto por organismos oficiales como por entidades particulares, para evitar el peligro de desaparición de dichas razas

Experimental uncertainty and covariance information in EXFOR library

Compilation of experimental uncertainty and covariance information in the EXFOR Library is discussed. Following the presentation of a brief history of information provided in the EXFOR Library, the current EXFOR Formats and their limitations are reviewed. Proposed extensions for neutron-induced reaction cross sections in the fast neutron region and resonance region are also presented.JRC.D.4-Standards for Nuclear Safety, Security and Safeguard

AXA: a computer program for the management of the Canary Goat Group milking control programs

A computer program, developed in Clipper, for the management of the genealogical and productive information from the Canary Goat Group, is described. The two first sections of this program are planned for the males and females genealogical data arrangement. Third section is devised for the productive data storage. Fourth section is constructed for the emission of reports and finally, fifth section is a miscellaneous of utilities, where the connection with other programs must be highlighted. Also an exit control is enclosed. The basic purposes of this program aim the emission of official production reports for the Administration and farmers, and the information processing for its analysis in programs of genetic selection.Se describe un programa de ordenador, desarrollado en Clipper, para la gestión de la información genealógica y productiva de la Agrupación Caprina Canaria. Sus dos primeras secciones se ocupan de la organización de la información genealógica de machos y de hembras; la tercera de la información productiva; la cuarta de la elaboración de informes y la quinta es una miscelánea de utilidades y un control de salida, con conexión con otros programas. Las misiones básicas del programa se centran en la emisión de informes productivos oficiales, destinados a la administración y a los ganaderos, y la preparación de la información para su análisis en programas de selección genética

Angular distributions of protons scattered by 40 Ar nuclei with excitation of the 2 + (1.46 MeV) and 3 − (3.68 MeV) collective levels for incident energies of 25.1, 32.5, and 40.7 MeV

Elastic and inelastic scattering of unpolarized and polarized protons by 40Ar nuclei for incident energies between 20 and 50 MeV has been studied by reanalyzing experimental scattering spectra for the 2+(1.46 MeV) and 3-(3.68 MeV) levels in the angular range 30º–160º for incident protons of energies of 25.1, 32.5, and 40.7 MeV. An isospin dependent soft-rotator coupled-channels optical model with the potential containing a dispersive term with a nonlocal contribution is used to analyze the data

Caracterización de grasas para caldos deshidratados

Fats represent a major part of the weight of dehydrated soup cubes. As these products are stored at room temperature, the fatty components should show no partial melting during the Summer months. Six fatty raw materials, mixtures of these fats already prepared by the manufacturer and lipidic extracts from the finished cubes (both hen and vegetables soups) are analyzed in this work, trying to relate origin (fatty acid composition) with stability against temperature changes (DSC thermogram). Some of the studied fats are found acceptable according to the expected shelf life of the product, although others should be modified before usage, either by fractioning or by hydrogenation.Las grasas constituyen un alto porcentaje del peso de los caldos deshidratados envasados bajo forma de cubitos. Como estos alimentos se almacenan a temperatura ambiente, sus componentes grasos no deben fundir parcialmente durante el verano. En este trabajo se analizan seis muestras de materias primas grasas, mezclas de ellas ya preparadas por la empresa elaboradora y extractos lipidióos del producto terminado (sopas de gallina y de verduras). Se busca relacionar la naturaleza de las grasas (composición en ácidos grasos) con su estabilidad frente a variaciones de la temperatura (termogramas por DSC). Se concluye que, si bien algunas de las grasas estudiadas son aceptables desde el punto de vista de la vida útil esperada del producto, otras se deberían modificar por hidrogenación o fraccionamiento antes de su uso

Parameterisation of the residual temperature distribution based on the modelling of successive emission of prompt neutrons

A new deterministic modelling taking into account the successive emission of prompt neutrons from initial fragments of a fragmentation range {A, Z, TKE} constructed as in the Point-by-Point (PbP) treatment is described. The good agreement of different prompt emission quantities obtained from this modelling (e.g. v(A), v(TKE), E-γ(A), E-γ(TKE), etc.) with the experimental data and the results of the PbP model and other Monte-Carlo models validates the present modelling of sequential emission. The distributions of different residual quantities, including the residual temperature distributions P(T) of light and heavy fragments allow to obtain a new parameterisation of P(T) which can be used in the PbP model and the Los Alamos model

The effect of colostrum source (goat vs. sheep) and timing of the first colostrum feeding (2h vs. 14h after birth) on body weight and immune status of artificially reared newborn lambs

Several factors can affect lamb body weight (BW) and immune status during the first days of life, including colostrum source and timing of the first colostrum feeding. The aim of this study was to evaluate the effects of colostrum source (goat or sheep) and timing of the first colostrum feeding (2 or 14h after birth) on lamb BW and immune status. In this study, 40 lambs were removed from their dams at birth and randomly assigned into 4 groups of 10 lambs each. Lambs were subsequently fed at 2 or 14h after birth with goat or sheep colostrum. Blood samples and BW recording were performed before feeding. Blood plasma was used to measure the immunoglobulin concentration (IgG and IgM), chitotriosidase activity, and complement system activity (total and alternative pathways). In general, no differences in any of the measured variables were observed among the 4 groups, indicating that neither colostrum source nor timing of the first colostrum feeding had an effect on these variables. These findings may improve management on lamb farms that raise animals under artificial conditions, because our results indicate that it is not necessary to feed colostrum to lambs immediately after birth and that goat colostrum may be used to feed newborn lambs
