Enhancement of overloaded waste stabilization ponds using different pretreatment technologies: a comparative study from Namibia

Journal of Water Reuse and Desalination, 2020
Waste stabilization ponds (WSP) are a well-established wastewater treatment technology in Namibia. However, they are often overloaded and we still lack concepts and technologies for improvement.

Nitrification-denitrification in WSP: a mechanism for permanent nitrogen removal in maturation ponds [PDF]

, 2009
A pilot-scale primary maturation pond was spiked with 15N-labelled ammonia (15NH4Cl) and 15N labelled nitrite (Na15NO2), in order to improve current understanding of the dynamics of inorganic nitrogen transformations and removal in WSP systems.

Estimation of Ascaris infection risks in children under 15 from the consumption of wastewater-irrigated carrots [PDF]

, 2009
Ascaris lumbricoides, the large human roundworm, infects ,1,200 million people, with children under the age of 15 being particularly at risk. Monte Carlo quantitative microbial risk analyses were undertaken to estimate median Ascaris infection risks in

Elephant‐Skin‐Inspired Porous Cementitious Tiles with Programmable Crack Networks for Passive Cooling

Advanced Materials, EarlyView.
Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Spatial Detection of Microsphere Polystyrene Plastics and Molecular Remodeling within a Full‐Body Mouse with MALDI Trapped Ion Mobility Mass Spectrometry Imaging

Angewandte Chemie, EarlyView.
Orally administered polystyrene microplastics accumulate in murine tissues and are detected using MALDI‐MSI with TIMS. Lipid profiling reveals decreases in hexosylceramides, sphingomyelins, and ether‐linked phospholipids, indicating altered metabolism.

Targeting Lactate and Lactylation in Cancer Metabolism and Immunotherapy

Advanced Science, EarlyView.
Lactate, once deemed a metabolic waste, emerges as a central regulator of cancer progression. This review elucidates how lactate and its epigenetic derivative, protein lactylation, orchestrate tumor metabolism, immune suppression, and therapeutic resistance.

CONJUGATE TREATMENT OF LEACHATE FROM LANDFILL AND SEWAGE IN DOMESTIC STABILIZATION PONDS

Journal of Urban and Environmental Engineering, 2016
In Brazil, the per capita generation of municipal solid waste is approximately 0.80 kg hab-1 day-1, which implies daily production of 156 tons, whereas on average 50% of this quantity of waste is composed mainly of putrescible organic material that will ...

Nitrogen removal in maturation WSP ponds via biological uptake and sedimentation of dead biomass [PDF]

, 2009
In this work a set of experiments was undertaken in a pilot-scale WSP system to determine the importance of organic nitrogen sedimentation on ammonium and total nitrogen removals in maturation ponds and its seasonal variation under British weather ...

Delivery of Pleckstrin‐Homology Domains Suppresses PI3K/Akt Signaling and Breast Cancer Metastasis

Advanced Science, EarlyView.
Current therapies curb tumor growth but not metastasis. Obscurin, a giant metastasis suppressor lost in breast cancer, restrains PI3K/Akt signaling but is impractical to restore. We deploy a mini‐obscurin, comprising the obscurin‐PH‐domain, which sequesters PI3K‐p85, potently suppressing invasion and metastasis.

PREPARATORY STUDY CONTROL OF LARVAE AND PUPA INSECTS IN STABILIZATION PONDS

Iranian Journal of Public Health, 1987
With increasing urbanization and industrialization, the volume of domestic sewage and industrial effluents are growing. So, now a days we need to consider the wastewaters as a secondary water resource, without impairing the health and well being of man ...
