Whole Life Costing

There is an increasing pressure from the economic regulator in England and Wales for water companies to ensure that their capital maintenance decisions reflect an understanding of the long-term impact on their operational costs and risks. This implies that decisions must not only reflect the costs borne now but the likely costs in the future, and how these might be optimised. It is noteworthy that within the construction and transport industries, asset management decisions which have been driven in this direction utilise a whole life costing (WLC) methodology. This paper addresses the implications of transferring the concept of WLC to service-based assets such as water systems. A WLC approach to distribution network management aims to achieve the lowest network provision and operating cost when all costs are considered to achieve standards enforced by regulation. Cognisance is to be taken of all relevant costs - direct and indirect, private and societal - in order to balance the needs of the service supplier, the customer, society and the environment in a sustainable manner. A WLC analysis thus attempts to develop a cost profile over the life of the asset. Accounting for the costs over this period is achieved through a combination of activity based costing (ABC) and a life cycle assessment (LCA) used to identify potential social and environmental costs. This process means that each of these identified costs must be linked to some physical parameter that itself varies over time due to changing demands on the system, the different operational strategies available to the operator and natural deterioration of the fabric of the system. The links established between the cost and activities of the operator provide the basis for the development of a WLC decision tool (WiLCO) for application to water distribution network management.

Activated Sludge Processes

The purpose of this paper is to present the background and examples of methodology which enable environmental engineers and scientists to analyze activated sludge processes much more effectively than is otherwise possible with conventional approaches. Good process analyses are key for devising optimal design and operational strategies. The key features to the technique presented herein are the field-proven predictability of the model and the methodology for collecting data needed for calibrating the process model. Case histories prove the predictability of the model that is associated with the process analysis approach. The advantage of the approach advocated herein is the use of respirometric techniques to calibrate the model. These methods enable the process analyst to collect the requisite data for model calibration in twenty-four hours or less. This feature enables one to use this process analysis methodology for both design and operational applications. The paper will present the technical basis for the process model and how respirometric methods are utilized to compute biokinetic constants in a manner which is consistent with kinetic theory. Case histories will be discussed that demonstrate the predictability of the modeling approach and demonstrate the utility of this tool for process analysis.

One of the benefits of collaborating in an interprofesional team is the exchange, and the acquisition of knowledge, skills and operational strategies alongside this community. Here, we share an example and an analogy from the medical field: A biomedical engineer, from a simulation center, who has the task of preserving the functionality, integrity and aesthetics of the simulators and the equipment, acquires a role similar to that of a doctor who seeks strategies that focus on maintaining a healthy population. The following is a review of our experience in the Centro de Enseñanza por Simulación de Posgrado (CESIP) of the National Autonomous University of Mexico (UNAM). It should be noted that none of the strategies stated here can be considered as a reference “of excellence” for the operation of a simulation center, due to the great number of particularities in each of them. Finally, we are convinced that sharing our experience may be useful for other centers, especially due to the lack of information available.

This paper takes the application of workflow technology in a multi-smart IOT message-driven practical training execution system as the research background, analyzes the current situation and problems of the practical training execution system, and reconstructs and optimizes the original on-site practical training model and business methods according to the future development needs of the practical training execution system. This study draws on the theoretical perspective of the computer knowledge body to deeply recognize and understand the connotation of computing ability from the levels of knowledge, skills, and attitude, forms a basic understanding of computing ability through literature combing, and refines the core elements of computing ability through a combination of enterprise case study, content analysis, and questionnaire survey, strives to form a more systematic and in-depth understanding of the connotation and elements of computing ability. It also provides a reference for the clarification of computing ability training objectives of computer science teachers under the trend of intelligence. Facing the enhancement of computing ability of engineering students majoring in computer science at the undergraduate level, the objectives of computing ability cultivation are clarified, the key points of computing ability cultivation mode are refined from three levels: curriculum design, teaching operation, management, and control, and three typical computing ability cultivation modes embedded in undergraduate computer education are constructed: knowledge module combination mode, computing context experience mode, and intelligent industry-leading mode. The operational strategies and implementation paths of the models are discussed in depth. This study emphasizes that, based on the analysis of the characteristics of the trend of intelligence, the computing ability cultivation model is not static.

(1) Background: The surgical table within a typical ambulatory surgery operating room is frequently rotated and placed in different orientations to facilitate surgery or in response to surgeon preferences. However, different surgical table orientations can impact access to different work zones, areas and equipment in the OR, potentially impacting workflow of surgical team members and creating patient safety risks; (2) Methods: This quantitative observational study used a convenience sample of 38 video recordings of the intraoperative phase of pediatric outpatient surgeries to study the impacts of surgical table orientation on flow disruptions (FDs), number of contacts between team members and distance traveled; (3) Results: This study found that the orientation of the surgical table significantly influenced staff workflow and movement in the OR with an angled surgical table orientation being least disruptive to surgical work. The anesthesia provider, scrub nurse and circulating nurse experienced more FDs compared to the surgeon; (4) Conclusions: The orientation of the surgical table matters, and clinicians and architects must consider different design and operational strategies to support optimal table orientation in the OR.

Objectives: (i) to describe the operational strategies implemented to practise electroconvulsive therapy (ECT) safely, and (ii) to explore the effect of the lockdown and operational strategies on the characteristics of patients who received ECT during the initial 6 months of the COVID-19 lockdown. Methods: At first, the operational strategies that were implemented at the Broadmeadows ECT suite were summarised. Subsequently, the characteristics of patients who received ECT in the lockdown period (16 March–16 September 2020) and in the comparison period (16 March–16 September 2019) were compared. Results: Many safety measures were implemented, and there was no COVID-19 infection among mental health staff and patients. In the lockdown period, the number of patients (23.9%) and the total number of ECTs (29.4%) were less. This pattern was more prominent among the aged patients. Conclusion: Safe practices are essential to provide ECT during lockdowns even when the community transmission of COVID-19 is high.
