Net Zero Corridors: A Case Study Approach from Perth, Australia to Decarbonize Urban Power and Transport

Received: 27 February 2023;  Published: 17 November 2023;  doi: 10.21926/jept.2304036

Abstract

The transition to net zero cities is a pivotal challenge in the face of climate change. This research introduces a novel methodology termed "Net Zero Corridors," which emphasizes a bottom-up approach to decarbonize urban power and transport systems. By focusing on urban corridors, this method integrates distributed power systems with urban transport, offering a localized solution to the broader challenge of urban decarbonization. Drawing from urban fabric theory and urban metabolism data, the study provides insight [...]

Acute Exercise on Reversal Learning

Received: 15 July 2019;  Published: 09 October 2019;  doi: 10.21926/obm.neurobiol.1904043

Abstract

Objective: Reversal learning requires an individual to alter their behavior when previously learned reward-based contingencies are reversed. Reversal learning is heavily influenced by cognitive flexibility, which has been shown to be enhanced with acute exercise. However, minimal work has directly evaluated the effects of acute exercise on reversal learning, which was the purpose of this experiment. Methods: A between-subject randomized controlled intervention was employed. Participants (N=60) were randomized into [...]

Optimization of Heat Transfer in Parabolic Trough Collectors Using Advanced Turbulator Designs and Nanofluids

Received: 19 October 2024;  Published: 15 January 2025;  doi: 10.21926/jept.2501003

Abstract

Parabolic trough collectors (PTCs) are essential for solar thermal energy systems, and their thermal efficiency can be significantly enhanced using turbulators and nanofluids. This numerical study introduces three novel fin-spiral turbulator configurations (4, 7, and 10 blades) to enhance heat transfer within the absorber tube. Additionally, three nanofluid types including water-based single-walled carbon nanotubes (SWCNT), cupric oxide (CuO), and a hybrid SWCNT-CuO, at concentrations of 1%, 3%, and 5% were evaluat [...]

Effectiveness of Mindfulness-Based Stress Reduction (MBSR) Interventions on Mindfulness and Stress Symptoms for Cancer Patients: A Quantitative Assessment

Received: 21 January 2024;  Published: 13 March 2024;  doi: 10.21926/obm.icm.2401019

Abstract

The aim of this article is to provide a quantitative assessment of the correlation between heightened mindfulness and stress reduction among cancer patients and survivors who engaged in Mindfulness-Based Stress Reduction (MBSR) interventions. Utilizing data from eight studies, we conducted quantitative analyses to provide the effectiveness scores of MBSR interventions on mindfulness, assessed using the Mindful Attention Awareness Scale (MAAS), and stress symptoms, evaluated through standardized self-reported questi [...]

A Switched-Reluctance Motor Drive Powered by Switch-Mode Rectifier with Battery Energy Storage Buffer

Received: 23 December 2020;  Published: 07 April 2021;  doi: 10.21926/jept.2102016

Abstract

This paper presents a three-phase full-bridge boost switch-mode rectifier (SMR) fed switched-reluctance motor (SRM) drive with energy storage buffer. First, the power circuits and control schemes of the two power stages are properly designed. Except for having good line drawn power quality, the boostable DC-link voltage of the SRM drive can enhance the SRM driving performance in wide speed range. And the recovered regenerative braking energy can be sent back to the grid successfully. Then, a battery storage system [...]

How do Water Companies Address Environmental Indicators in their ESG Reports?

Received: 26 July 2023;  Published: 30 January 2024;  doi: 10.21926/aeer.2401006

Abstract

As climate change is becoming an increasingly crucial issue, it has become critical for firms to report on their Environmental, Social, and Governance (ESG) aspects. In particular, this research analyzes how environmental indicators are dealt with and reported on. In the case study examined, namely the company American Water Works, GHG emissions and water management were the most important issues to the stakeholders according to the materiality assessment. It was found that the firm has significantly reduced its GH [...]

On the Face of It: Social Heuristics Are Mediated by Age and Sex, But Not by Faciometrics

Received: 16 February 2020;  Published: 23 June 2020;  doi: 10.21926/obm.geriatr.2002124

Abstract

The ability to situate individuals within social categories provides an important social function, allowing people to navigate problems of survival and reproduction within highly complex social structures. This categorization of people with apparently shared characteristics is facilitated by various cues, one of the most important being facial information. There has been a wealth of literature that reports on perceptions of characteristics informed by faciometrics (or the measurement of facial features and associat [...]

Glasgow Coma Scale Scores and Impact of Delirium on Intubated Seizure Patients Treated with Phenytoin and Lacosamide: Retrospective Analysis and Literature Review

Received: 29 November 2023;  Published: 05 July 2024;  doi: 10.21926/obm.neurobiol.2403230

Abstract

Studies have shown that decrease in time intubated is associated with better prognosis. Delirium is associated with increased duration of mechanical ventilation and Intensive Care Unit (ICU) length of stay. However, there is limited report on delirium in intubated seizure patients. As per report, low Glasgow Coma Scale (GCS) increased the risk of delirium and thus increasing ICU length of stay. Information on delirium and outcome in intubated seizure patients receiving lacosamide versus phenytoin is limited. Our re [...]

Volt-Var Control for Utility-Scale Solar PV Plants to Downsize SVCs and Curtailment Effects

Received: 09 March 2023;  Published: 03 August 2023;  doi: 10.21926/jept.2303026

Abstract

One way to increase solar photovoltaic penetration in the grid is the management of voltage fluctuations. This is because a photovoltaic plant cannot be interconnected to the grid if it causes voltage violations. Voltage violation is where voltage exceeds the acceptable range. Often, grid operators request photovoltaic plant owners to regulate voltage sufficiently with expensive and space-consuming static Var compensators. Unfortunately, this sometimes makes the project less feasible. This paper argues that there a [...]

Drainage in a Screw Press and Utilization of the Recovered Fibres after Thermo-Hydrolytic Disintegration of Waste Fibreboards

Received: 15 March 2021;  Published: 22 July 2021;  doi: 10.21926/rpm.2103029

Abstract

A thermo-hydrolytic disintegration process qualifies as a promising option for recycling the waste MDF and preserving the fibrous morphology of the recovered lignocellulosic fibre material. This study aims to include a drainage process between the thermo-hydrolytic disintegration and the further utilization of the recovered fibres (RF) obtained using a screw press for removing the disintegration water (DW). In this context, the chemical properties of the RF (pH, nitrogen content, formaldehyde emissions) and the DW [...]
