Optimization of Lignin Peroxidase, Manganese Peroxidase, and Lac Production from Ganoderma lucidum Under Solid State Fermentation of Pineapple Leaf

This study was undertaken to isolate ligninase-producing white-rot fungi for use in the extraction of fibre from pineapple leaf agriwaste. Fifteen fungal strains were isolated from dead tree trunks and leaf litter. Ligninolytic enzymes (lignin peroxidase (LiP), manganese peroxidase (MnP), and laccase (Lac)), were produced by solid-state fermentation (SSF) using pineapple leaves as the substrate. Of the isolated strains, the one showing maximum production of ligninolytic enzymes was identified to be Ganoderma lucidum by 18S ribotyping. Single parameter optimization and response surface methodology of different process variables were carried out for enzyme production. Incubation period, agitation, and Tween-80 were identified to be the most significant variables through Plackett-Burman design. These variables were further optimized by Box-Behnken design. The overall maximum yield of ligninolytic enzymes was achieved by experimental analysis under these optimal conditions. Quantitative lignin analysis of pineapple leaves by Klason lignin method showed significant degradation of lignin by Ganoderma lucidum under SSF

Influence of education levels on dissemination of soil fertility management information in the central highlands of Kenya

Inadequate links between researchers and farmers has resulted in low uptake of research advances recommended to improve food security in the central highlands of Kenya. Access to timely and accurate information by extension agents and farmers is paramount in dissemination of soil fertility management practices. Hence, the study sought to investigate the effect of education levels on communication channels used to disseminate soil fertility technologies in the Central highlands of Kenya. Questionnaires were used to elicit information from 105 extension agents and 240 farmers. About 50.5% of the extension officers were certificate holders while 29.5% were diploma holders from agricultural institutes. Majority of the farmers had attained primary education (59.6%) while 25.8% and 9.2% had attained secondary and post secondary education, respectively. Research institutions were the most accessible sources of information on soil fertility management practices by extension agents while internet and scientific conferences were the least scored as accessible sources of soil fertility management information by extension agents. Education levels significantly influenced preference of individual approach methods by farmers. There was a significant positive relationship between education and accessibility of internet as a source of information on green manure. The implication of the study was that education levels influenced the mode of communication used in the transfer of soil fertility research outputs to the end users. Consequently, it is extremely important to consider education levels in selection of dissemination pathways used in agriculture.

Provision of information and documentation on education in the Austrian Federal Ministry of Education. 'Provisión de información y documentación en educación en el Ministerio Federal de Educación de Austria'.

En un país pequeño como Austria es necesario recibir estímulo del exterior a nivel europeo respectivamente internacional para que los responsables vean lo útil que son las iniciativas nacionales en el campo de documentación educativa. Trabajar de manera comparativa en un contexto europeo ayuda a comprender mejor su propia posición y sirve de base para tomar decisiones y para desarrollar nuevos proyectos en el futuro. Ha crecido el interés en utilizar la información y documentación educativa durante las últimas décadas. Actualmente los ministros de educación ya no pueden seguir su trabajo sin recurrir a todos aquellos datos que han sido recopilados en los respectivos países y presentados a través de las redes europeas como EURYDICE, la red europea de información en educación (htttp://www.eurydice.org).

I Don`t Want to Present the ECAES! Quality of Education in Health Careers

This paper makes a reflection about a panorama of higher education quality, and referring to that it reviews and discusses what should be ongoing, what was made in history and what is today in curse, that is the basic strategies used by the government to improve higher education. An emphasis is made on higher education quality tests (ECAES, in Spanish) for health careers, in order to solve some doubts in students and teachers about those tests. My excuses to the reader for often using first person and some references of personal interviews or unprinted conferences.

Education for all : the future of education and training for 14-19 year olds.

Aborda varias cuestiones a la luz de las pruebas recogidas durante cinco años por el Informe Nuffield sobre la educación y formación entre los 14 y los 19 años, al plantear dos preguntas clave que están en el centro del debate actual sobre educación y formación de los jóvenes, con independencia de su origen, capacidades u objetivos: ¿Qué se considera una persona educada de 19 años, hoy en día? ¿Son los modelos de educación que hemos heredado del pasado suficientes para satisfacer las necesidades de todos los jóvenes, así como las necesidades sociales y económicas de la comunidad en general? Escrito por los co-directores del Informe Nuffield, sus autores abogan por una radical remodelación y una visión más amplia de la educación con vistas al futuro.
