Variable Step Size P&O Algorithms for Coalescing Pump/Deoiling Hydrocyclone Produced Water Treatment System

2020

This paper presents three variable step size P&O algorithms for optimizing the separation efficiency of a coalescing pump/deoiling hydrocyclone produced water treatment system. By continuously adjusting the pumping pressure, and subsequently the coalescing effect, the algorithms are used to minimize the oil concentration downstream the hydrocyclone. Due to the variable step size, the algorithms react rapidly to changes in the upstream produced water characteristics, at the same time as they reduce (or eliminate) steady-state oscillations. Based on both simulation and experimental testing, the study discusses advantages and disadvantages of the algorithms.

The long-term use of psychiatric services within the Open Dialogue treatment system after first-episode psychosis

2017

AbstractOpen Dialogue is a family-oriented early intervention model for mental health problems developed in the health district of Western Lapland, Finland. In the present study, the aim was to describe how psychiatric services were used in Western Lapland after decades of first-episode psychosis services, and to analyze how baseline characteristics were related to re-admission rates and the total duration of psychiatric treatment in geographical area where Open Dialogue approaches were developed and efforts made to systematically apply them to all psychiatric treatments. The data were obtained from the medical histories of patients who had first-episode psychosis in 1992–2005 and who lived…

Efficacy of removing Thermafil and GuttaCore from straight root canal systems using a novel non-surgical root canal re-treatment system : a micro-com…

2021

The present study aims to evaluate the effectiveness of an XP-endo non-surgical root canal re-treatment system in removing both GuttaCore and Thermafil gutta-percha carrier-based root canal filling materials from straight root canal systems using micro-computed tomography (micro-CT) analysis. The study was performed on 20 single-rooted upper teeth, which were randomly allocated into the following study groups: Group A, Thermafil and AH Plus sealer (n = 10)

Impact assessment of a solar powered water treatment project

2015

Water treatment technologies are seen as the best alternative to be considered for adoption in developing countries where access to portable water supply that is free of pathogens is yet a challenge. This study intended to assess impact brought forth by a project, which employed a water treatment technology in rural settings of Morogoro Region in Tanzania. The project used solar photovoltaic panels to trap solar energy, converted to mechanical power to treat water with the help of sterilization ultraviolet membrane. A comparative analysis was used as an assessment framework to study impacts of the project with respect to the quality of approach used during the project life cycle. Determinan…
