Effects of Chemical Modification on Removal of Pollutants with Carbon and Nitrogen from Aqueous Solution by Zeolite

open access: yes工程科学与技术, 2015
:The effects of six chemical modification agents of acetic acid, citric acid, sodium citrate, SDS, sodium chlorite, and HDTMA on the removal rates of low concentration of ammonia nitrogen, nitrate nitrogen and COD by zeolite were studied.

Assessing membrane aerated biofilm reactor configurations in mainstream anammox applications

open access: yesWater Science and Technology, 2022
Partial nitritation anammox (PNA) membrane aerated biofilm reactors (MABRs) have the potential to be employed in mainstream wastewater treatment and can drastically decrease the energy and carbon requirements for nitrogen removal.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Daytime and nighttime removal processes of atmospheric NO2 and NH3 in Araraquara's region – SP

open access: yesEclética Química, 2018
Nitrogen oxides and ammonia are important nitrogen compounds which are emitted to the atmosphere. They are very important substances in the environment. In the atmosphere, these substances may undergo diverse reactions that result in changes of chemical ...

New anaerobic process of nitrogen removal

open access: yesWater Science and Technology, 2006
This paper reports on successful laboratory testing of a new nitrogen removal process called DEAMOX (DEnitrifying AMmonium OXidation) for the treatment of strong nitrogenous wastewater such as baker's yeast effluent. The concept of this process combines the recently discovered ANAMMOX (ANaerobic AMMonium OXidation) reaction with autotrophic ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Autotrophic nitrogen removal at low temperature

open access: yesWater Science and Technology, 2011
In this work the autotrophic nitrogen removal was carried out at moderately low temperatures using two configurations: a) two-units one comprising a SHARON reactor coupled to an Anammox SBR and b) single-unit one consisting of a granular SBR performing the CANON process.

The temperature response of nitrate removal in denitrification beds [PDF]

open access: yes, 2014
The addition of reactive nitrogen (Nᵣ) to agricultural systems has helped crop production match human population growth. However, the addition of Nᵣ comes at a cost to environment in the form of ozone destruction, habitat degradation and biodiversity ...

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

open access: yesMolecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Autotrophic nitrogen removal after ureolytic phosphate precipitation to remove both endogenous and exogenous nitrogen

open access: yesWater Science and Technology, 2013
Anaerobic digestion yields effluents rich in ammonium and phosphate and poor in biodegradable organic carbon, thereby making them less suitable for conventional biological nitrogen and phosphorus removal. In addition, the demand for fertilizers is increasing, energy prices are rising and global phosphate reserves are declining.
