To investigate the possible biochemical metabolisms for excess phosphate uptake in a sequencing batch reactor (SBR) with single-stage oxic process, which was reported using glucose as the sole carbon source previously, glucose and acetate were fed to two SBRs as the sole carbon source, respectively. The changes of polyhydroxyalkanoates (PHAs), glycogen and the removal of phosphorus were compare...

Most livestock and poultry odors are generated by the anaerobic decomposition of livestock wastes such as manure (feces and urine), spilled feed, bedding materials, and wash water. Increased organic loading rates due to expanding animal numbers, slug loading, concentrated waste streams, and/or inadequate amounts of dilution water increase the potential for odor emissions from waste management s...

Problem. With the experience of special purpose vehicles operating in field, there is a problem electrical start-up diesel engines at low temperatures. It caused by an increase motor oil viscosity, as well decrease starter batteries capacity. Goal. The goal work to investigate possibilities using molecular energy storage for reliable start-up, including temperatures, aimed improving efficiency ...

Future energy systems with a large share of fluctuating renewable energies demand thermal storages that are flexible and reliable. Sodium acetate trihydrate (SAT) has been investigated for many years as heat storage materials but the focus investigations were mostly on short-term applications. SAT high density supercooling degree which make it an ideal material. Heat utilizing stable can store ...

In the past few years, the data warehouse (DW) has regained experts’ interest due to the paradigm shift from data storages to data analysis. During the development of DWs data passes through a number of transformations and are staged in multiple storages which might lead to data corruption and/or manipulation. Hence, testing DWs is a vital stage in the DW development life cycle. In this paper, ...

The automated material handling system (AMHS) is a highly automated transport solution of actual 300mm semiconductor waferfabs. The big logistic challenge in such a running system is the just-in-time delivery of lots (carriers). Therefore, beside tracks and vehicles, there are different storages (stocker) and buffers (under track storages and load ports) integrated in such a transport system. T...
