Caracterización molecular de la pérdida del poder patógeno en Agrobacterium tumefaciens

2003

Agrobacterium tumefaciens es una bacteria fitopatógena causante de tumores en el cuello y raíces de muchas especies vegetales de interés económico. En los viveros e invernaderos es donde más daños produce, al aparecer episodios epidémicos que pueden impedir la comercialización de producciones enteras, porque las plantas afectadas por esta enfermedad no pueden ser comercializadas. Los estudios epidemiológicos y de dinámica de poblaciones del patógeno son poco abundantes y han incidido en aspectos del desarrollo y mantenimiento de la enfermedad producida por la bacteria. Aunque se ha señalado el predominio de cepas no patógenas frente a patógenas en ambientes en los que las cepas productoras …

Testing of the SPEDE conversion electron spectrometer at ISOLDE

2017

Työssä testattiin uutta SPEDE-ilmaisinta CERNin ISOLDE-laboratorion MINIBALLkoeasemalla, jossa selvitetään ytimien rakenteita käyttämällä radioaktiivia suihkuja. Ilmaisimen testauksessa käytettiin radioaktiivisia Bi-207 ja Hg-191 lähteitä. SPEDE-ilmaisimella pystytään havaitsemaan sisäisen konversion elektroneja. Ytimen viritystilan purkautumisessa sisäinen konversio on kilpaileva prosessi tavanomaisemmalle γ-emissiolle. Sisäistä konversiota tutkimalla saadaan selvitettyä ytimen rakenteen ominaisuuksia kuten esimerkiksi E0-siirtymät ytimissä. SPEDE-ilmaisin mahdollistaa samanaikaiset γ- ja elektronispektrometriset mittaukset MINIBALL-koeasemalla. Työssä käytettiin kokeellisten mittaustulost…

Inter and intra-guild interactions in egg parasitoid species of the soybean stink bug complex

2002

Abstract – The objective of this research was to evaluate the parasitism behavior of Telenomus podisiAshmead, Trissolcus basalis (Wollaston) e Trissolcus urichi Crawford (Hymenoptera: Scelionidae) oneggs of Nezara viridula L., Euschistus heros F., Piezodorus guildinii Westwood and Acrosternumaseadum Rolston (Heteroptera: Pentatomidae), in no choice and multiple choice experiments. For allparasitoid species, the results demonstrated the existence of a main host species that maximizes thereproductive success. The competitive interactions among the parasitoid species were investigated inexperiments of sequential and simultaneous release of different combinations of parasitoid pairs on thehosts…

Precio no monetario percibido en alojamientos e-peer-to-peer. La perspectiva de los huéspedes de Airbnb

2021

[EN] Price is considered as a key variable in predicting buying behavior. However, few studies have focused on how non-monetary price is affected and can affect other components of the consumer endogenous variables. This paper seeks (1) to analyze the effects of antecedents of behavioural price (past experience, the benefits and risks of peer to peer accommodation services) on the guest perceived price, and (2) to determine the effect of this price and past experience on guest intentions. With a sample of 136 Airbnb guests and the use of SEM, results show that past experience, financial risk, and time risk influence the non-monetary perceived price. This price and past experience affect gue…
