Assimilation of Zenith Wet Delay observations using the ensemble Kalman Filter in a Poly-ZWD empirical model over the USA

Journal of Atmospheric and Solar-Terrestrial Physics
Modeling the spatial and temporal variability of water vapor in the lower atmosphere is crucial for meteorological and geodetic applications, as it directly influences weather prediction and satellite-based positioning. However, traditional empirical models often struggle to capture rapid water vapor fluctuations, limiting their accuracy and practical ...

Potentiometric and NMR Study of Aminoalkylphosphinic Acids ZWD their Complexing Properties

Phosphorus, Sulfur and Silicon and the Related Elements, 1990
Abstract Ethylenediamine-tetrakis- [methylene(phenylphosphinic)] acid, piperidine [methylenephosphinio] acid and piperasine-bis- thylenephoaphinic] acid have been prepared by the method of Plaza and Grim1 and Meier2. Their dissociation constants and stability constants with Mg2+, Ca2+, Sr2+, Ba2+, Mn2+, Fe2+, Co2+ and Ni2+ have been determined.

Development of a zero water discharge (ZWD)—Recirculating aquaculture system (RAS) hybrid system for super intensive white shrimp (Litopenaeus vannamei) culture under low salinity conditions and its industrial trial in commercial shrimp urban farming in Gresik, East Java, Indonesia

Aquacultural Engineering, 2018
Abstract This study aims to develop a hybrid zero water discharge (ZWD) - recirculating aquaculture system (RAS) system to improve water quality, as well as the growth, survival, and productivity, of the super-intensive white shrimp culture under low salinity conditions at semi-mass and the industrial level.

Towards zero waste discharge (ZWD) in agar production: Gracilaria dura byproduct-based activated carbon for sustainable environmental remediation

International Journal of Biological Macromolecules
Gracilaria dura; red seaweed used in agar production; generates substantial processing waste (PWs); including residual seaweed-mass (RSM) and aqueous alkaline waste (AAW). In this study; 1 kg G. dura processed for the production of 250 ± 5 g agar; 350 ± 25 g RSM and 12.5 ± 0.5 kg AAW.
