Driving forces for changes in geographical distribution of Ixodes ricinus ticks...
Medlock, J.M.; Hansford, K.M.; Bormane, A.; Derdakova, M.; Estrada-Peña, A.; George, J-C; Golovljova, I.; Jaenson, T.G.; Jensen, J-K; Jensen, P.M.Many factors are involved in determining the latitudinal and altitudinal spread of the important tick vector Ixodes ricinus (Acari: Ixodidae) in Europe, as well as in changes in the distribution within its prior endemic zones. This paper builds on published literature and unpublished expert opinion from the VBORNET network with the aim of reviewing the evidence for these changes in Europe and discusses the many...
Production, characterization and application of activated carbon from brewer’s ...
Mussatto, Solange I.; Fernandes, Marcela; Rocha, George J. M.; Órfão, José J. M.; Teixeira, J. A.; Roberto, Inês ConceiçãoDifferent types of activated carbon were prepared by chemical activation of brewer’s spent grain (BSG) lignin using H3PO4 at various acid/lignin ratios (1, 2, or 3 g/g) and carbonization temperatures (300, 450, or 600 °C), according to a 22 full-factorial design. The resulting materials were characterized with regard to their surface area, pore volume, and pore size distribution, and used for detoxification of ...
Activated carbon production from brewer’s spent grain lignin
Mussatto, Solange I.; Fernandes, Marcela; Rocha, George J. M.; Orfão, J. J. M.; Teixeira, J. A.; Roberto, Inês ConceiçãoActivated carbons are adsorbents that are industrially used in multiple processes for product separation and purification, and for the treatment of liquid and gaseous effluents. Despite its frequent use in the water and waste industries, activated carbons remain an expensive material. In view of the high cost and the tedious procedures for the preparation and regeneration of activated carbons, there is a contin...
Hydrogen peroxide bleaching of cellulose pulps obtained from brewer’s spent grain
Mussatto, Solange I.; Rocha, George J. M.; Roberto, Inês ConceiçãoBrewer’s spent grain (BSG) was evaluated for bleached pulp production. Two cellulose pulps with different chemical compositionswere produced by soda pulping: one from the original raw material and the other from material pretreated by dilute acid. Both of them were bleached by a totally chlorine-free sequence performed in three stages, using 5% hydrogen peroxide in the two initial, and a 0.25 NNaOHsolution in t...
Systemic lupus erythematosus in Europe at the change of the millennium:Lessons ...
Cervera, R.; Abarca-Costalago, M.; Abramovicz, D.; Allegri, F.; Annunziata, P.; Ayditung, A.; Bacarelli, M.; Bellisai, F.; Bernardino, I.The bEuro-Lupus CohortQ is composed by 1000 patients with systemic lupus erythematosus (SLE) that have been followed prospectively since 1991. These patients have been gathered by a European consortium—the bEuro-Lupus Project GroupQ. This consortium was originated as part of the network promoted by the bEuropean Working Party on SLEQ, a working group created in 1990 in order to promote research in Europe on the...
Flora e estrutura do estrato lenhoso numa comunidade de Cerrado em Santo Antôni...
Borges,Hélida B. Nogueira; Shepherd,George Jflora e características estruturais do estrato arbustivo-arbóreo. Um total de 131 espécies, 92 gêneros e 45 famílias foram registrados na área. As famílias com maior riqueza de espécies foram: Leguminosae, Myrtaceae, Rubiaceae, Annonaceae e Malpighiaceae, com 43% (56/131) das espécies e 38% (35/92) dos gêneros. Análise de dados sobre a similaridade florística, pelos índices de Jaccard (IJ) e Sørensen (IS), com ...
A New ent-Clerodane Diterpene from Hymenaea courbaril var. altissima
Nogueira,Raquel T.; Giacomini,Rosana A.; Shepherd,George J.; Imamura,Paulo M.A new ent-clerodane and two known ent-labdanes were isolated from the barks of Hymenaea courbaril var. altissima (Ducke). The new diterpene was identified, after esterification with diazomethane, as methyl (-)-(5R,8S,9S,10R)-clerod-3-en-15-oate and known diterpenes were identified as methyl (-)-copalate and methyl (-)-eperuate. From the EtOAc extract of seed pods a known methyl (-)-zanzibarate was isolated. The...
