This study proposes an innovative biodiesel technology based on heat-integrated reactive absorption. Rigorous simulations embedding experimental results were performed in AspenTech AspenONE engineering suite to design this novel process and evaluate the technical and economical feasibility. The main results are given for a plant producing 10 ktpy biodiesel from waste vegetable oil with high fre...

The reuse and management of organic waste can reduce significantly the impact on environment human health, as well improve economic value through developing value-added products certain applications. One solutions to cut down is solid such fruit vegetable into ecoenzymes via fermentation. This current review discusses production, characterization, application ecoenzymes. data was gathered from ...

This study explores how ‘gatherings’ turn into ‘encounters’ in a virtu­al world (VW) context. Most communication technologies enable only focused encounters between distributed participants, but VWs both gatherings and can occur. We present close sequential analysis of moments when after silent gathering, inter­action among participants VW is gradually resumed, also investigate the social actio...

Process participants need to learn how to perform in the context of their business processes. Process training is challenging due to cognitive difficulties in relating process model elements to real world concepts. In this paper we present a 3D Virtual World (VW) process training approach for office environments. In this VW, process participants can experience a process in an immersive environm...

BACKGROUND Waste animal fat is a promising feedstock to replace vegetable oil that widely used in commercial biodiesel process, however the high content of free fatty acid in waste fat makes it unfeasible to be processed with commercial base-catalytic process. Enzymatic process is preferable to convert waste fat into biodiesel since enzyme can catalyze both esterification of free fatty acid and...

We report six BeppoSAX X–ray observations of VW Hyi during and after the outburst of Sep 23 1998. The outburst flux is lower than the quiescent flux in the entire observed energy band (0.1–10 keV), in agreement with earlier observations. The X–ray spectra are fitted with two-temperature plasma and cooling flow spectral models. These fits show a clear spectral evolution in X–rays for the first t...

The Mandiri Community Partnership Program (PKM) “Training on Vegetable Waste Treatment as Duck Feed in South Ternate District” will be conducted with the partner farmer groups of Buku Sasa cand find out about processing vegetable waste duck feed nutritional content according to needs ducks based maintenance. PKM is carried objectives (1) Breeders can utilize which widely available and its avail...
