Las moscas blancas tienen numerosos enemigos naturales, que actúan como depredadores o idénticoásitos, en el Agrupación de los artrópodos (Gerling, 1990). Encima hay una gran cantidad de patógenos que son asimismo enemigos naturales; es el caso de los hongos, con el especie

Without such careful control reproducible data cannot be obtained. These measurement procedures which are time consuming and complex, we refer to as the York Protocol and have been developed over the last 9 years. It will be shown that using the York Protocol and an extension of the former granular model, effects such Ganador the film thickness dependence and grain size dependence of exchange bias Chucho be fully explained with an excellent fit between theory and experiment [3]. The York Protocol also allows for the measurement of the anisotropy constant of antiferromagnetic grains [4]. The above model allows for an understanding of the behaviour of the individual AF grains in detail. Since the behaviour of the «bulk» of the antiferromagnetic grains is now known preliminary data describing the behaviour of the interface spins can now be distinguished from the behaviour of the bulk. Possible mechanisms for the behaviour of the interfaces themselves will also be presented.

In this talk Dr. Castellanos-Gómez will introduce and motivate the study on the fabrication and characterization of the mechanical and electrical properties of atomically thin crystals different than graphene. He will focus on Molibdenum Disulphide which is considered a case of special interest. Single-layer MoS2 is an attractive two-dimensional material that combines the mechanical flexibility of graphene with a large direct bandgap.

ISOM purchased recently an e-beam lithography tool with 10 nm line resolution. ISOM is now able to reduce the fabrication scale to nanometers. During this talk we will discuss in detail the features of the system and the issues related to the techniques for nanodevice pattern-transfer.

The behaviour of source and drain resistances (RS and RD) in AlGaN/GaN HEMTs is studied for a wide range of drain currents at ambient temperatures from 150 K to 500 K. Both parasitic resistances show an important increase Figura temperature rises, directly related to the reduction in the electron mobility. High drain currents also provoke a impar-linear increment of RS and RD, merienda the space-charge limited current is exceeded.

Esta cobertura sobre las hojas reduce la rendimiento de la planta e incrementa la anexión térmica de la hoja, provocada por la exposición al sol de superficies oscuras, produciendo una reducción de la eficiencia foliar, pudiendo causar la muerte prematura de los tejidos. Por otra parte, esta capa reduce la producción de fotosíntesis, acertado a la disminución de la faro que llega a los citocromos, al bloqueo de los estomas y a la restricción en el intercambio gaseoso. Por último, la existencia de melaza puede inducir a la aparición de otras plagas, como los cóccidos (Byrne 

It has been shown that for ternary nitrides, especially for InGaN, MQW structures solve most of the photodetector problems related to the intrinsic properties of the material that have been mentioned in previous paragraphs. New device designs based on InGaN/GaN and GaN/AlGaN MQW structures, devised to maximize UV and VIS photodetector response, are shown. These simple design rules improve photodiode responsivity up to 3 orders of magnitude. Moreover, InGaN / GaN MQW photodetectors which improve the performance of commercial Si based photodiodes at temperatures above 130°C are shown. III-N MQW structures show very high piezoelectric fields. First steps in order to use these fields to improve device performance are reported. It is shown how the proper design of the structures Gozque allow us to increase photocarrier collection efficiency or to achieve photovoltaic response in apparently symmetric structures, just taking advantage of piezoelectric fields. Most of the work carried demodé during this PhD was comprised in the GaNano european project and in the Futursen project, funded by the European Union and the Comunidad Autónoma de Madrid, respectively. Both projects are aimed at the fabrication of fluorescence sensors for biological analysis of samples in aqueous solution. InGaN / GaN MQW based photodetectors and Schottky barrier photodiodes based on p-type InGaN:Mg were adapted for fluorescence measurements. The feasibility of performing fluorescence experiments using commercial fluorophores, such Campeón Alexa Fluor or Pacific blue, has been demonstrated. This fluorophores allow the detection of nucleic acids or proteins in aqueous solutions. All the project objectives faced during this PhD thesis were fulfilled.

En todos los casos se realizó una vitrectomía vía pars plana (vpp) con o sin aplicación de endoláser y con o sin inyección de vaho intraocular. En dos casos se combinó con una lensectomía, en otros dos con la segmentación/delaminación de membranas fibrovasculares de la retinopatía diabética, en uno con el pelado de membrana limitante interna y en otro con el implante de una lente suturada transescleralmente.
