Anaerobic co-digestion of fruit and vegetable waste: Synergy and process stability analysis
Journal of the Air and Waste Management Association, 2021Anaerobic mono- and co-digestion of fruits and vegetable waste (FVW), slaughterhouse waste (SHW), and cattle manure (CM) under mesophilic conditions (35°C) were conducted through biochemical methane potential tests to investigate how the FVW in a co ...

Flexible nitrite supply alternative for mainstream anammox: Advances in enhancing process stability.
Environmental Science and Technology, 2020Anaerobic ammonium oxidation (anammox) has attracted extensive attention as a potentially sustainable and economical municipal wastewater treatment. However, its large-scale application is limited by unstable nitrite (NO2--N) production and associated ...

Nonthermal Stabilization Processes
2016The processing of food by nonthermal technologies—such as high pressure, pulsed electric fields, and ultrasound—is gaining relevance within the food industry. Fresh-tasting foods along with minimal impact on nutritional attributes, low energy consumption, minimal and fast processing, environmental-friendliness, effectiveness at inactivating pathogenic ...

Chloroplast RNA processing and stability
Photosynthesis Research, 2004Primary chloroplast transcripts are processed in a number of ways, including intron splicing, internal cleavage of polycistronic RNAs, and endonucleolytic or exonucleolytic cleavages at the transcript termini. All chloroplast RNAs are also subject to degradation, although a curious feature of many chloroplast mRNAs is their relative longevity.

Process stability for GTAW-based additive manufacturing
Rapid prototyping journal, 2019Purpose Traditional gas tungsten arc welding (GTAW) and GTAW-based wire and arc additive manufacturing (WAAM) are notably different. These differences are crucial to the process stability and surface quality in GTAW WAAM.

Microcrystalline silicon deposition: Process stability and process control
Thin Solid Films, 2007Applying in situ process diagnostics, we identified several process drifts occurring in the parallel plate plasma deposition of microcrystalline silicon (µc-Si:H). These process drifts are powder formation (visible from diminishing dc-bias and changing spatial emission profile on a time scale of 100 s), transient SiH4 depletion (visible from a ...

Enzyme stability in downstream processing part 1: Enzyme inactivation, stability and stabilization
Biotechnology Advances, 1992In biotechnological recovery processes the instability of the product can lead to large losses in the sequence of recovery processes needed to purify the product. As the cost of the final active product is strongly dependent on the recovery yield, this will lead to an increase in product cost.

Abstract In this paper passivity analysis is used to determine if a system is stable, and if not is used to design a stabilizing distributed control system. The analysis is done using a thermodynamic based storage function that is similar to exergy or available work.

Adjustment Processes and Stability
1987Economic theory is pre-eminently a matter of equilibrium analysis. In particular, the centrepiece of the subject — general equilibrium theory — deals with the existence and efficiency properties of competitive equilibrium. Nor is this only an abstract matter. The principal policy insight of economics — that a competitive price system produces desirable
