La Conservació dels murals de la capella de Sant Miquel del Reial Monestir de Santa Maria de Pedralbes

Quan l'abadessa del monestir de Pedralbes estableix en el contracte de Ferrer Bassa que els murals de la capella de Sant Miquel es facin a l'oli segurament fa referència a una tècnica pictòrica consistent a aglutinar els pigments amb oli i a la seva aplicació damunt d'una capa prèvia feta a base de blanc de plom. Però la tècnica que ens trobem no és aquesta: si bé s'utilitza l'oli, s'empren altres aglutinants proteics i resines terpèniques, essent la fase prèvia una pintura al fresc. Els murals estan pintats al fresc i al sec gairabé en la mateixa proporció,i la distribució dels dos procediments està perfectament planificada abans de començar a pintar. També està previst fer la profusa decoració amb daurats i platejats. Els principals problemes de conservació són es inherents a la utilització d'aglutinants orgànics. La tècnica executiva és l'element que més ha condicionat la conservació dels murals, mentre que l'ambient estable de la capella i la seva ubicació han permès que aquest cicle pictòric hagi superat prop de set-cents anys d'història en un estat molt intacte i complet.

Effects of Surface Properties and Wood Modification into Direct Printing on Wood

Building industry is a high volume branch which could provide prominent markets for wood based interior decoration solutions. Competition in interior decoration markets requires versatility in appearance. Versatility in wood appearance and added value could be achieved by printing grain patterns of different species or images directly onto wood. The problem when planning wood printing’s implementing into durable applications is basically how to transfer a high quality image or print sustainably onto wood, which is porous, heterogeneous, dimensionally unstable, non-white and rough. Wood preservation or treating, and modification can provide durability against degradation but also effect to the surface properties of wood which will effect on printability. Optimal adhesion is essential into print quality, as too high ink absorbance can cause spreading and too low ink absorbance cause pale prints. Different printing techniques have different requirements on materials and production. The direct printing on wood means, that intermedias are not used. Printing techniques with flexible printing plates or in fact non-impact techniques provide the best basis for wood printing. Inkjet printing of wood with different mechanical or chemical surface treatments, and wood plastic composite material gave good results that encourage further studies of the subject. Sanding the wood surface anti-parallel to the grain gave the best overall printing quality. Spreading parallel to the grain could not be avoided totally, except in cases where wood was treated hydrophobic so adhesion of the ink was not sufficient. Grain pattern of the underlying wood stays clearly visible in the printed images. Further studies should be made to fine tune the methods that already gave good results. Also effects of moisture content of wood, different inks, and long-term exposure to UV-radiation should be tested.

Characterization of nontypable haemophilus influenzae isolates recovered from adult patients with underlying chronic lung disease reveals genotypic and phenotypic traits associated with persistent infection

Nontypable Haemophilus influenzae (NTHi) has emerged as an important opportunistic pathogen causing infection in adults suffering obstructive lung diseases. Existing evidence associates chronic infection by NTHi to the progression of the chronic respiratory disease, but specific features of NTHi associated with persistence have not been comprehensively addressed. To provide clues about adaptive strategies adopted by NTHi during persistent infection, we compared sequential persistent isolates with newly acquired isolates in sputa from six patients with chronic obstructive lung disease. Pulse field gel electrophoresis (PFGE) identified three patients with consecutive persistent strains and three with new strains. Phenotypic characterisation included infection of respiratory epithelial cells, bacterial self-aggregation, biofilm formation and resistance to antimicrobial peptides (AMP). Persistent isolates differed from new strains in showing low epithelial adhesion and inability to form biofilms when grown under continuous-flow culture conditions in microfermenters. Self-aggregation clustered the strains by patient, not by persistence. Increasing resistance to AMPs was observed for each series of persistent isolates; this was not associated with lipooligosaccharide decoration with phosphorylcholine or with lipid A acylation. Variation was further analyzed for the series of three persistent isolates recovered from patient 1. These isolates displayed comparable growth rate, natural transformation frequency and murine pulmonary infection. Genome sequencing of these three isolates revealed sequential acquisition of single-nucleotide variants in the AMP permease sapC, the heme acquisition systems hgpB, hgpC, hup and hxuC, the 3-deoxy-D-manno-octulosonic acid kinase kdkA, the long-chain fatty acid transporter ompP1, and the phosphoribosylamine glycine ligase purD. Collectively, we frame a range of pathogenic traits and a repertoire of genetic variants in the context of persistent infection by NTHi.

Detection and coat protein gene characterization of an isolate of Grapevine virus B from corky bark-affected grapevines in Southern Brazil

An isolate of Grapevine virus B (GVB), obtained by indexing Vitis labrusca and V. vinifera grapevines on the indicator LN33, was transmitted mechanically to several Nicotiana species. The virus was partially purified from N. cavicola and the coat protein estimated at 23 kDa by SDS-PAGE. In negatively stained leaf extracts of experimentally inoculated N. cavicola and N. occidentalis, flexuous particles with cross banding were observed, predominantly measuring 750-770 x 12 nm, with a modal length of 760 nm. Decoration indicated a clear, positive reaction against AS-GVB. In DAS-ELISA, GVB was detected in N. cavicola and grapevine extracts, and Western blots showed homologous and cross reaction of GVB and GVA antisera with GVB coat protein. Using specific primers for GVB, a fragment of 594 bp, comprising the coat protein gene coding for 197 amino acids, was amplified by RT-PCR with viral RNA extracted from GVB-infected N. occidentalis. The nucleotide and the deduced amino acid sequences of the coat protein gene showed high identities with Italian and Japanese isolates of GVB.

The Role of networks in the internationalization process of Finnish design companies

Finnish design has attracted global attention lately and companies within the industry have potential in international markets. Because networks have been found to be extremely helpful in a firm’s international business operations and usefulness of networks is not fully exploited, their role in Finnish design companies is investigated. Accordingly, this study concentrates on understanding the role of networks in the internationalization process of Finnish design companies. This was investigated through describing the internationalization process of Finnish design companies, analyzing what kind of networks are related to internationalization process of Finnish design companies, and analyzing how networks are utilized in the internationalization process of Finnish design companies. The theoretical framework explores the Finnish design industry, internationalization process and networks. The Finnish design industry is introduced in general and the concept of design is defined to refer to the industries of textiles, furniture, clothing, and lighting equipment in the research. The theories of internationalization process, the Uppsala model and Luostarinen’s operation modes, are explored in detail. The Born Global theory, which is a contrary view to stage models, is also discussed. The concept of network is investigated, networks are classified into business and social networks, and network approach to internationalization is discussed. The research is conducted empirically and the research method is a descriptive case study. In this study, four case companies are investigated: the interior decoration unit of L-Fashion Group, Globe Hope, Klo Design, and Melaja Ltd. Data is collected by semi-structured interviews and the analysis is done in the following way: the case companies are introduced, their internationalization processes and networks are described and, finally, the comparison of the case companies is done in a form of cross-case analysis. This research showed that cooperation with social networks, such as locals or employees who have experience from the target market can be extremely helpful in the beginning of a Finnish design company’s internationalization process. This study also indicated that public organizations do not necessarily enhance the internationalization process in a design company point-of-view. In addition, the research showed that there is cooperation between small Finnish design companies whereas large design companies are not as open to cooperation with competitors.

Missale (C.ö.IV.9, Oripään missale II)

A (mainly votive) missal consisting of seven distinct parts. Put together in several stages, somewhat haphazardly. Parts II and III are probably the oldest parts. The final stage in the composition of the book is probably the addition of part VII. Part II belongs in the same liturgical tradition as C.ö.IV.7 (Oripään Missale I), probably that of Diocese of Linköping. Part III, a votive missal, is an informal copy of a book that would most probably have been used close to a Swedish cathedral (Linköping?). How the present book found its way to Oripää chapel is not known.
