Abstract
This article demonstrates government and foreign direct investment in influencing the formation and development of the electronics cluster in Guadalajara, Mexico. The organizational limitations and the lack of planning in the technological learning process aside, the triple helix paradigm has become critical in upgrading the electronics industry in Guadalajara. The study analyzes technology transfer and its adaptation through technical and research cooperation within national and international innovation systems. It also examines the role of multinational corporations within the triple helix model, and how they impact upon the formation, growth and development of an electronics cluster in Guadalajara.

Brucellosis is still an important public health problem throughout the world, but principally in developing countries such as Mexico. The aim of the present study was to describe frequency of musculoskeletal involvement in 14 consecutive patients with the suspect infection of brucellosis. All patients came from the brucellosis high prevalent region. Methods. An analysis for musculoskeletal involvement was carried out on 14 consecutive patients with brucellosis. The diagnosis was supported by the isolation of a Brucella sp. or a four-fold increase in serum anti-brucella antibodies. Results. Seven patients were females and 7 males, ranging in age from 19 to 64 years (mean 31 years). Ten patients had one or more positive cultures and anti-brucella antibodies were high prevalent. Myalgias were the most common musculoskeletal manifestation (92%), followed by polyarthralgias (71%), lumbalgia (57%), peripheral arthritis (28%) and dorsalgia (21%). Bilateral sacroiliitis was less common. In three patients with lumbalgia, the computerized tomography images were compatible with herniated intervertebral disk. Conclusion. In this series the musculoskeletal involvement had a high prevalence. Muscle and joint pain were the main forms of clinical presentation. Peripheral arthritis and the axial involvement seem to have complications associate with functional disability. We suggest that, when in an endemic area, brucellosis had to be considered into diagnosis possibilities for musculoskeletal symptoms, even if manifestations include lumbalgia plus sciatica. In addition, surgical remotion of intervertebral disk should be delayed and reconsidered once 6 weeks of antimicrobial therapy active against brucella had been accomplished.",,,,,,,,,"http://hdl.handle.net/20.500.12104/43336","http://www.scopus.com/inward/record.url?eid=2-s2.0-69549108599&partnerID=40&md5=00cb67550db236a4cbdc2bd4db791992",,,,,,"3",,"Gazzetta Medica Italiana Archivio per le Scienze Mediche",,"143 147",,"168",,"Scopus",,,,,,"Bone diseases; Brucella melitensis; Brucellosis; Communicable diseases",,,,,,"On the musculoskeletal involvement in patients with brucellosis from an endemic area",,"Article"

Lopez Mena, E. Martinez, A.H.",,"2007",,"The perovskite Gd0.9Ba0.1CoO3 was prepared via solution and solution-polymerization methods in aqueous media. The thermal decomposition of precursor powders produced well crystallized nanostructured materials possessing an extensive nanoporosity. The average particle size obtained by the solution route was 150 nm, whereas by the solution-polymerization method was 61 nm. The characterization of gas response, performed on thick-films, revealed that the electrical resistance variation increases with reducing grain size. In oxygen, the films prepared with powder of solution-polymerization registered an increment of 1000%, compared to the powder made by the solution route, whereas in carbon dioxide was 1100%.
