Content objects are essential links between Knowledge Management and E-Learning systems. Therefore content authoring and sharing is an important, interdisciplinary topic in the resp. fields. In this paper, we want to critically elaborate on the “user as producer and consumer”-concept for content production and consumption. We address the subject by using the notion of content collaboration as e...

IrO 2 is the most stable oxygen evolution reaction (OER) catalyst in acidic media and it has been widely used as co-catalyst to mitigate cell reversal damages anode of PEM fuel cells (PEMFCs). In this study, a mechanistic understanding degradation an under transient operation PEMFC provided. Thermogravimetric analysis (TGA) reductive atmosphere (3.3 vol.% H /Ar) shows that not containing at ope...

Abstract The variations in pH and Dissolve Oxygen (DO) concentrations were analysed surface river water samples for three seasons Pre-Monsoon, Monsoon Autumn (January to December 2022) four major rivers Ganga, Yamuna, Gomti Hindon flowing through Uttar Pradesh, India. For Ganga range varied from 7.65 8.47 DO 6.4mg/l 9.26mg/l. Yamuna 7.31 10.5 0 8.1mg/l. showed, between 7.2 8.48, while 0.63mg/l ...

Cross-sectional transmission electron microscopy was used to study defect formation and evolution in the !001" Ge and Si wafers implanted with 1 MeV Si+ and 40 keV Si+ at a dose of 1 !1014 cm−2. As expected, upon annealing, the #311$ extended defects form and subsequently dissolve at the projected range for nonamorphizing implants into Si. However, in Ge, no #311$ defect formation is observed f...

The Karnafully is one of the most important rivers due to its profound influence on water chemistry and sediment characteristics. The present study intended to assess the quality of water and sediment from intertidal zone of this river in respect to the pollution index. Seasonal water and sediment samples were collected during four seasons (Monsoon, post-monsoon, winter, and pre-monsoon) of 201...

The need for effective and adaptive technologies carbon dioxide (CO2) mitigation targeting global net-zero emissions is critically growing. Hence, innovative CO2 reduction have attracted worldwide interest from scientific research communities. use of liquid metals the conversion into or solid carbonaceous products has gained increasing attention in recent years due to their high activity resist...

The main bottleneck in fermentation technology is scaling up procedure of industrial enzymes according to the biological characteristics organism. current study describes production kinetics cellulases stirred tank reactor by using mutant and wild strains T. dupontii. span both bioreactor was examined. It found strain dupontii time required for optimum reduced 48h as compared 72h strain. kineti...
