"Camelid nanobodies raised against an integral membrane enzyme, nitric oxide reductase." Protein Sci. 18 (2009): 619-28. AbstractWebsite

Nitric Oxide Reductase (NOR) is an integral membrane protein performing the reduction of NO to N(2)O. NOR is composed of two subunits: the large one (NorB) is a bundle of 12 transmembrane helices (TMH). It contains a b type heme and a binuclear iron site, which is believed to be the catalytic site, comprising a heme b and a non-hemic iron. The small subunit (NorC) harbors a cytochrome c and is attached to the membrane through a unique TMH. With the aim to perform structural and functional studies of NOR, we have immunized dromedaries with NOR and produced several antibody fragments of the heavy chain (VHHs, also known as nanobodies). These fragments have been used to develop a faster NOR purification procedure, to proceed to crystallization assays and to analyze the electron transfer of electron donors. BIAcore experiments have revealed that up to three VHHs can bind concomitantly to NOR with affinities in the nanomolar range. This is the first example of the use of VHHs with an integral membrane protein. Our results indicate that VHHs are able to recognize with high affinity distinct epitopes on this class of proteins, and can be used as versatile and valuable tool for purification, functional study and crystallization of integral membrane proteins.

Ferreira, Jorge Controlo de Geradores de Indução Duplamente Alimentados em Turbinas Eólicas. Eds. Mário Neves, and João Pina. FCT-UNL, 2009. Abstract

A instalação em larga escala de turbinas eólicas equipadas com um gerador de indução duplamente alimentado (GIDA) tem vindo a promover a realização de vários estudos relacionados com potenciais soluções para a sua integração na rede eléctrica. Nesta tese apresenta-se uma técnica de controlo que permite regular as potências activa e reactiva do GIDA de forma estável e independente. A sua viabilidade é suportada não só por um estudo teórico prévio mas também pelos resultados da simulação de modelos desenvolvidos usando o software Matlab?Simulink?. Apesar de este sistema funcionar a velocidade variável (ainda que dentro de certos limites), continua a existir a necessidade de limitar a potência fornecida pela turbina eólica quando a velocidade do vento assume valores superiores ao nominal. Assim, faz-se também uma breve análise de alguns métodos de regulação de potência activos e passivos.
