Experimentarium as arena for common learning during change processes

The initiating question guiding this study is how employee participation can be established during an organisational change process in order to ensure the employees' involvement in the design of their future work environment. A case study where an "experimentarium" (learning lab) was set up in a medium size Danish company is presented in this paper. The case study demonstrates that it is feasible to generate employee participation in designing their future working environment in the experimentarium when careful attention is given to the influence of situational factors and a stringent pedagogical method is utilised

Off-season biogenic volatile organic compound emissions from heath mesocosms: responses to vegetation cutting

Biogenic volatile organic compounds (BVOCs) affect both atmospheric processes and ecological interactions. Our primary aim was to differentiate between BVOC emissions from above- and belowground plant parts and heath soil outside the growing season. The second aim was to assess emissions from herbivory, mimicked by cutting the plants. Mesocosms from a temperate Deschampsia flexuosa-dominated heath ecosystem and a subarctic mixed heath ecosystem were either left intact, the aboveground vegetation was cut, or all plant parts (including roots) were removed. For 3–5 weeks, BVOC emissions were measured in growth chambers by an enclosure method using gas chromatography-mass spectrometry. CO(2) exchange, soil microbial biomass, and soil carbon and nitrogen concentrations were also analyzed. Vegetation cutting increased BVOC emissions by more than 20-fold, and the induced compounds were mainly eight-carbon compounds and sesquiterpenes. In the Deschampsia heath, the overall low BVOC emissions originated mainly from soil. In the mixed heath, root, and soil emissions were negligible. Net BVOC emissions from roots and soil of these well-drained heaths do not significantly contribute to ecosystem emissions, at least outside the growing season. If insect outbreaks become more frequent with climate change, ecosystem BVOC emissions will periodically increase due to herbivory

Etablering af et kommunalt citylogistik center

I dette paper vil vi ved brug af et eksempel fra Københavns kommune se på, hvordan man kan fastlægge om der er et grundlag for etablering af en kommunal terminal. Vi vil gennemgå forskellige løsningsmuligheder, vurdere fordele og ulemper, se på omfanget af aktivitet i et center, hvilke forskellige krav det stiller ikke kun til leverandørerne, men i lige så høj grad til kommunen som indkøbsorganisation.  Vurderingerne er foretaget ved at se på indkøbsomfang, typiske leveringsmønstre og geografi. Vi har indsamlet viden fra andre lignende løsninger, vurderet omkostningsniveauet og gennemført dialoger med både de kommunale indkøbere og leverandører og transportører.  Konklusionen er, at der er grundlag for at gå videre med et sådant projekt, men også at en del forskellige elementer skal afklares og undersøges dybere inden 'spaden sættes i jorden'.&nbsp

Cellulolytic and Xylanolytic Microbial Communities Associated With Lignocellulose-Rich Wheat Straw Degradation in Anaerobic Digestion

The enzymatic hydrolysis of lignocellulosic polymers is generally considered the rate-limiting step to methane production in anaerobic digestion of lignocellulosic biomass. The present study aimed to investigate how the hydrolytic microbial communities of three different types of anaerobic digesters adapted to lignocellulose-rich wheat straw in continuous stirred tank reactors operated for 134 days. Cellulase and xylanase activities were monitored weekly using fluorescently-labeled model substrates and the enzymatic profiles were correlated with changes in microbial community compositions based on 16S rRNA gene amplicon sequencing to identify key species involved in lignocellulose degradation. The enzymatic activity profiles and microbial community changes revealed reactor-specific adaption of phylogenetically different hydrolytic communities. The enzymatic activities correlated significantly with changes in specific taxonomic groups, including representatives of Ruminiclostridium, Caldicoprobacter, Ruminofilibacter, Ruminococcaceae, Treponema, and Clostridia order MBA03, all of which have been linked to cellulolytic and xylanolytic activity in the literature. By identifying microorganisms with similar development as the cellulase and xylanase activities, the proposed correlation method constitutes a promising approach for deciphering essential cellulolytic and xylanolytic microbial groups for anaerobic digestion of lignocellulosic biomass
