Evaluation of sewer network resilience index under the perspective of ground collapse prevention

open access: yesWater Science and Technology, 2022
Generally, when evaluating the resilience of infrastructure, the four properties of resilience (robustness, rapidity, resources, and redundancy, 4Rs) are widely considered. However, there is little research on the resilience assessment of sewer networks.

Biodegradation Studies of Fiber-Reinforced Melamine and Phenol Formaldehyde Polymer Composites in Soil and Wastewater Systems

open access: yesJournal of Natural Fibers
The biodegradation of polymer composites in soil and sewer wastewater systems is a complex but essential area of study for mitigating environmental pollution. To address this issue, obtaining materials that are sustainable is the need of the hour.

ASSESSMENT OF A GROUNDWATER QUALITY FOR DRINKING PURPOSE IN ILORIN, NIGERIA

open access: yesAcademy Journal of Science and Engineering, 2022
Groundwater is a major source of water supply in Nigeria where there is an inadequate supply of water for domestic, industrial and agricultural uses. This paper examines the suitability of water samples from a target hand dug well (TW) in a residential ...

cAMP-stimulated transcription of DGKθ requires steroidogenic factor 1 and sterol regulatory element binding protein 1

open access: yesJournal of Lipid Research, 2013
Diacylglycerol kinase (DGK)θ is a lipid kinase that phosphorylates diacylglycerol to form phosphatidic acid (PA). We have previously shown that PA is a ligand for the nuclear receptor steroidogenic factor 1 (SF1) and that cAMP-stimulated expression of ...

Estimating Maintenance Costs of Sewer System

open access: yesBuildings, 2023
Maintenance costs of all types of buildings are most often ignored since they are incurred in the future. Potential investors are interested in capital costs—construction costs—while maintenance costs are considered as unimportant in the life cycle of a ...

An evolutionary approach to modelling concrete degradation due to sulphuric acid attack [PDF]

open access: yes, 2014
Concrete corrosion due to sulphuric acid attack is known to be one of the main contributory factors for degradation of concrete sewer pipes. This paper proposes to use a novel data mining technique, namely, evolutionary polynomial regression (EPR), to ...

Developing synthetic sewer pipe system for data-scarce domains in application for urban flood modeling

open access: yesHydrology Research, 2023
In urban flood modeling, the accuracy of surface and subsurface flow calculations greatly depends on the parameterization of the drainage system. Incorporating the influence of the sewer pipe system is, therefore, integral to accurately simulating urban ...

Application of Probabilistic Neural Networks in Modelling Structural Deterioration of Stormwater Pipes [PDF]

open access: yes, 2006
In Australia, when stormwater systems were first introduced over 100 years ago, they\ud were constructed independently of the sewer systems, and they are normally the responsibility\ud of the third level of government, i.e., local government or city ...
