Pulsed-field gel electrophoresis for the discrimination of Oenococcus oeni isolates from different wine-growing regions in Germany
2008
Reliable techniques are needed for the identification individual Oenococcus oeni strains with desirable flavor characteristics and to monitor the survival and contribution of inoculated and indigenous bacteria. Therefore, we investigated the suitability of pulsed-field gel electrophoresis (PFGE) for the discrimination of 65 O. oeni isolates from six different wine-producing regions in Germany. Among the restriction enzymes tested, genomic DNA digestions with Sfi I were most effective by displaying 56 (86%) different banding profiles. Our results underline the high capacity of PFGE for strain identification and differentiation. Cluster analysis of the DNA restriction patterns revealed no dis…
Toward Tin-Based High-Capacity Anode for Lithium-Ion Battery
2014
Electrochemical deposition of SnCo alloys inside the nanometric pores of commercial membranes is described. Composition, morphology and crystallographic structure of the synthesized nanostructured alloys are reported as well as the results of electrochemical tests carried out both in half-cell and in full battery configuration to investigate the performance of these SnCo alloys as anodes for lithium-ion batteries. Optimized depositions yielded nanostructured alloys that performed 200 deep galvanostatic cycles at C/2 and 30 °C with 80 % capacity retention and coulombic efficiency higher than 97 % after 40 cycles Moreover, charge-discharge rate capability tests showed the high performance of …
Performance of Nanostructured Electrode in Lead Acid Battery
2015
Lead acid batteries have a large number of potential advantages, but the high weight of lead limits their use in new technologies, like hybrid or electrical cars, which require light batteries with high specific energy. We tried to overtake this limit with nanostructured electrodes of PbO2 and Pb, obtained by electrodeposition in polycarbonate template. In the case of lead, to obtain electrodes with very good mechanical stability, a systematic investigation of electrodeposition process was needed to overcome the formation of dendrites that is the principal limitation of electrochemical production of metal lead. Nanostructured electrodes were tested in a zero gap configuration, using commerc…
Pediatric Urinary Diversion: Review and Own Experience
1992
New insights into the diseases of childhood, profound improvements and new developments in surgical techniques as well as the knowledge gained from long-term follow-up have altered the strategies and indications for urinary diversion in childhood. Continent urinary diversion is generally the method of choice. We are able to construct high capacity, low pressure reservoirs to protect the upper urinary tract and achieve continence. Nowadays, there is hardly any indication for permanent cutaneous urinary diversion. Temporary and intermediate cutaneous diversion are used only when serious conditions such as renal function deterioration occur. The possibility to convert any incontinent form of u…
Bibliometric Research in Technology-Mediated Learning with High Capacity Students
2020
RESUMEN: Este trabajo implica una revisión del trabajo de investigación sobre el aprendizaje mediado por tecnología en estudiantes de alta capacidad. El estudio fue realizado por medio de un análisis bibliométrico de la producción científica en la renombrada base de datos Scopus. Fueron evaluados, sin filtro temporal, 35 artículos publicados entre 1993 y 2018, de los cuales se analizó una selección de indicadores de productividad científica, colaboración, consumo e impacto, así como variables estructurales y de contenido. Aunque el número de artículos no sea muy alto, los resultados mostraron un aumento en las publicaciones científicas recientes centradas en procesos de aprendizaje mediados…
