Performing arts and mediation technology in the period of lockdown
2021
Advancements in digital technologies have become novel ways to enrich communication, expression, and transmission of arts knowledge. Technology is increasingly implemented in the performance space, as a source of inspiration for artists. Especially in this period of lockdown, mediation technology has turned out to be an essential tool for different aspects of social life, as in performing arts. With venues, schools and artistic activities closed, performers, students and spectators have been obliged to keep connecting in remote conditions. This article wants to retrace the aesthetic impact of mediation technology in performing arts during this period of lockdown by focusing on the aspects t…
Utilizing genetically engineered bacteria to produce plant-specific glucosides
2001
Plant-derived glucosides have attracted much attention due to their widespread applications. This class of products is difficult to isolate or to synthesize in pure form because of the resulting low yields. Thus, simple approaches for the generation of such glucosides would be highly beneficial. We purified and characterized a novel glucosyltransferase from plant cell suspension cultures of Rauvolfia serpentina, which showed rather low substrate specificity. We obtained its cDNA and expressed the active recombinant protein in bacteria (Escherichia coli) with excellent plant-specific glucosylation efficiencies. Compared with the plant system, the bacteria delivered the new enzyme, which was …
High-Yield Formation of Arbutin from Hydroquinone by Cell-Suspension Cultures ofRauwolfia serpentina
1992
High-density cell-suspension cultures of Rauwolfia serpentina cultivated in a nutrition medium optimized for the production of the glucoalkaloid raucaffricine synthesize hydroquinone glycosides from continuously added hydroquinone with a total yield of 23.87 g/1 (18 g/1 of arbutin and 5.87 g/1 of a hydroquinone diglycoside) in 7 days. This arbutin production is by far the highest formation of a natural product by plant-cell-culture systems reported to date.
Natural products and enzymes from plant cell cultures
1995
Plants represent an unlimited source of natural products. Many of the recently detected phytochemicals exhibit remarkable bioactivities, ranging from anticancer activity, phosphodiesterase inhibition to cytotoxicity against HIV-infected cells. Cultivated plant cells produce at their unorganized, dedifferentiated stage secondary metabolites, but in very different amounts in so far as new compounds are concerned. In fact, more than 140 novel natural products are presently known from plant cell cultures, which also include new metabolites formed by biotransformation. The biotransformation capacity of suspended cells is described and recent high yielding transformations, like the formation of a…

Managerial career plateaue : determinants, consequences and coping strategies
2008
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2008 During last decade managers who were practicing in different industries in Sri Lanka, have struggled with having less promotional opportunities. This initially leads them to become plateaued with their career. This study applied the theory from career management literature to examine factors significantly influenced to employees’ perception of being subjectively plateaued and objectively plateaued. Additionally, this study aims to identify the relationship between career plateauing and its implication toward job satisfaction, organizational commitment, intention to quit and job induced stress. Further, coping strategies …
