Stratification in Waste Stabilization Ponds I: Effects on Pond Parameters

Nigerian Journal of Technology, 2012
Stratification studies were carried out on the waste stabilization pond system at the University of Nigeria, Nsukka, Nigeria. Analysis of the samples collected with a water column sampler at 5cm and 0.1m apart showed some stratification of temperature, algae, pH, dissolved oxygen, coliform bacteria, chemical oxygen demand and nutrients.

Quantifying Spatio‐Operational Heterogeneity in Electrochemical Devices via Operando Correlative Neutron and X‐Ray Tomography

Advanced Functional Materials, EarlyView.
Heterogeniety in electrochemical systems heavily influences device performance and durability. The study shows unique evidence of spatio‐operational heterogeneity in fuel cells via operando neutron and X‐ray tomography. Large variations in membrane thickness and hydration depend upon location and operating conditions, with implications on membrane ...

Effluent polishing of the stabilization ponds at the university of zulia through rock filter

Revista Técnica de la Facultad de Ingeniería, 2010
Stabilization ponds represent an efficient alternative for the treatment of wastewater; however, the main disadvantage to them is the high concentration of solids in the effluent, which makes improving this effluent a necessary step to take.

Expanding Chemical Space of Nucleic Acid Nanoparticles for Tunable Antiviral‐Like Immunomodulatory Responses and Potent Adjuvant Activity

Advanced Functional Materials, EarlyView.
We introduce a nucleic acid nanoparticle (NANP) platform designed to be rrecognized by the human innate immune system in a regulated manner. By changing chemical composition while maintaining constant architectural parameters, we identify key determinants of immunorecognition enabling the rational design of NANPs with tunable immune activation profiles

A Vascular Microphysiological Model of Lung Fibrosis Reveals That Myofibroblasts and IPF Patient‐Derived Fibroblasts Impair Angiogenesis and Vasculogenesis

Advanced Functional Materials, EarlyView.
A microphysiological lung fibrosis model recapitulates myofibroblast–vascular interactions. Induced myofibroblasts and patient‐derived IPF fibroblasts impair angiogenesis and increase vascular permeability via TGF‐β1–driven signaling. Pharmacological interventions with SB 431542 and VEGF supplementation restore vascular morphology and barrier function.

Nile tilapia culture on domestic effluent treated in stabilization ponds. [PDF]

Biotemas, 2009
The performance and filet quality of tilapias (Oreochromis niloticus) culture in effluent stabilization lagoons was tested at the densities of 3 fish/m2 (T3), 7 fish/m2 (T2) and 7 fish/m2 in clean water + diet (T1) with 3 repetitions in tanks of 2.57m2 ...

Baffle and fixed media effects on coliform removal and bacterial die-off rate coefficient in waste stabilization ponds (a case study in Ahvaz) [PDF]

, 2017
Background: The use of waste stabilization ponds is one of the cheapest wastewater treatment processes. This study evaluated the effects of baffles and fixed media on coliform removal in facultative lagoons.

Generating Cell Surface Nucleated Hydrogels with an Artificial Membrane‐Binding Transglutaminase

Advanced Functional Materials, EarlyView.
Cell‐based therapies require advanced strategies to enhance cell delivery and bioactivity. Cell membrane engineering offers an avenue to impart new functions to delivered cells to boost their viability and function. Here, an artificial membrane‐binding transglutaminase is generated and biophysically characterized.

Computer-Aided Design for Stabilization Ponds

Water Science and Technology, 1992
It is urgently necessary to develop practical programs for different purposes in the field of wastewater treatment. Now the design programs for grit chambers, anaerobic ponds, facultative ponds, aerobic ponds, aerated ponds and polishing ponds are being developed. Programs for automated plotting and man-machine interactive plotting are needed too.
