A common cause failure model for components under age-related degradation
(Elsevier, 2020)
This paper discusses component age-related degradation and failure initiated from a shared cause and coupling factor (or mechanism) and the likelihood of the resulting common cause failure (CCF). For these components a CCF ...
Zero valent iron mediated degradation of the pharmaceutical diazepam
(Pergamon-Elsevier B.V. Ltd, 2012-07-01)
Parameters that influence the zero valent iron mediated degradation of the pharmaceutical diazepam (DZP) were evaluated including the iron concentration and its pre-treatment, the effect of complexation with EDTA and oxic ...

A Multivariate curve resolution approach to the study of the degradation kinetics of valsartan under photolytic and acid conditions
(Wiley, 2013-06)
The analysis of UV-spectrophotometric data with second-order chemometrics techniques, including multivariate curve resolution with alternating least-squares (MCR-ALS) and hybrid hard- and soft MCR (HS-MCR), was examined ...
Degradatión by pulsed corona discharges: study on the possible chemical degradatión pathway for diclofenac
(2015)
The remo val of hazardous organic pollutants such as polychlorinated biphenyls (PCB's),polycyclic aromatic hydrocarbons (benzopyrene, dibenzoanthracene), pesticides (DDT, lindane), and pharmaceutical products ( diclofenac, ...
Evaluation and degradation chemistry of orbifloxacin using LC-MS
(2013)
Orbifloxacin (ORBI) was subjected to different ICH (Q1A(R2)) prescribed stress conditions of thermal stress, hydrolysis, oxidation and photolysis. It was stable to dry heat (60 ºC) and photolysis (UV-VIS) in solid form. ...
The role of chain scission and chain branching in high density polyethylene during thermo-mechanical degradation
(Elsevier B.V., 2004-12-01)
The mechanical and thermo-oxidative degradation of high density polyethylene (HDPE) was measured in a twin-screw extruder using various processing conditions. Two types of HDPE, Phillips and Ziegler-Natta, having different ...
Probe-based qPCR assay enables the rapid and specific detection of bacterial degrading genes for the pesticide metaldehyde in soil
(2022-04)
Metaldehyde, a molluscicide pesticide, has been identified as a pollutant of concern due to its repeated detection in drinking water, thereby generating numerous compliance failures for water utilities. Biological degradation ...
