A Robust Second-Order Conic Programming Model with Effective Budget of Uncertainty in the Optimal Power Flow Problem

Received: 29 December 2021;  Published: 09 October 2022;  doi: 10.21926/jept.2204031

Abstract

Integrating large-scale wind energy in modern power systems necessitates high-efficiency mathematical models to address classical assumptions in power systems. In particular, two main assumptions for wind energy integration in power systems have not been adequately studied. First, nonlinear AC power flow equations have been linearized in most of the literature. Such simplifications can lead to inaccurate power flow calculations and result in technical issues. Second, wind power uncertainties are inevitable and have [...]

Effect of Convective Mixing Process on Storage of CO2 in Saline Aquifers with Layered Permeability

Received: 19 October 2020;  Published: 25 February 2021;  doi: 10.21926/acr.2101012

Abstract

Convective mixing of free-phase CO2 and brine in saline aquifers is an established technique to accelerate the CO2 dissolution process. Correct estimation of the convection onset time and rate of CO2 dissolution into brine are two crucial parameters regarding safety issues, as the timescale for dissolution corresponds to the same time over which the free-phase CO2 has a chance to leak out from the storage site. In real practice, underground formations are heterogeneous with a layered structure, but the convective m [...]

Hypnotic Regression as an Autoethnographic Modality for Exploring Adverse Childhood Experiences as Proposed Effectors of Chronic Adult Obesity - Selected Case Studies

Received: 09 March 2022;  Published: 26 September 2022;  doi: 10.21926/obm.icm.2203046

Abstract

Much has been written about the aetiological role of Adverse Childhood Experiences (ACEs) in the development of chronic adult physical and emotional health problems but current screening methods utilising questionnaires and formal interviewing often fail to show consensus across populations and surveys. This paper proposes that hypnotic regression might provide an alternative approach to ACE screening through its facility in revealing unsuspected and seemingly minor ACEs, which nevertheless can go on to have long t [...]

Wave Age and Steepness Relation in Growing Wind Seas: A Case Study during Hurricane Matthew in 2016

Received: 12 March 2023;  Published: 20 June 2023;  doi: 10.21926/aeer.2302037

Abstract

For wind-wave interaction studies, from the literature, two criteria for the wind sea are used: one is the wave age and the other wave steepness. Analysis of pertinent datasets from a data buoy near the passage of Hurricane Matthew in 2016 indicates that CpU10 = -15 HsLp + 1.3. Here CpU10 is the wave age and HsLp is the wave steepness, where Cp is the phase speed of the peak wave, U10 is the wind speed at 10 m, Hs is the significant wave height, and Lp is the peak or dominant wave length. It is found that 87% of th [...]

Association between Posttraumatic Stress Symptoms and Resilience in Frontline Healthcare Workers during the COVID-19 Pandemic in Vietnam

Received: 11 October 2023;  Published: 30 November 2023;  doi: 10.21926/obm.neurobiol.2304199

Abstract

The COVID-19 pandemic has placed a considerable burden on frontline healthcare workers (HCWs), thus increasing their vulnerability to developing posttraumatic stress disorder (PTSD). Our study aimed to examine the relationship between possible PTSD symptoms and resilience and identify associated factors with possible PTSD symptoms among Vietnamese frontline HCWs during the COVID-19 pandemic in 2021. We conducted a cross-sectional study across medical facilities at three administrative levels: provincial, district, [...]

Environmental Land Management and Assessment, in the Context of Resource and Climate-Related Conflict

Received: 23 November 2022;  Published: 12 June 2023;  doi: 10.21926/aeer.2302036

Abstract

This paper reviews the growing importance of satellite imagery to provide Normalized Difference Vegetative Index (NDVI) maps, relevant to environmental land management assessment, in the context of resource and climate-related conflict based upon our own humanitarian project-related support. Near real-time space-based monitoring benefits land assessment, human rights observers, and Non-Governmental Organizations (NGOs), in the presence of unstable regimes or socio-economic upheaval. Access to areas to validate clai [...]

Viral/Non-Viral Vectors in DNA/RNA Delivery Technology

Received: 26 August 2024;  Published: 12 December 2024;  doi: 10.21926/rpm.2404027

Abstract

Viral and non-viral vectors for nucleic acids (DNA/RNA) therapeutics are important in development of pharmaceutical industries. Although viral vectors have shown significant impact in transfection of DNA/RNA, but numerus studies have shown that non-viral vectors are also effective for the safe and targeted delivery of DNA/RNA to exact location in the body with high percentage of efficacy, safety, and low-immunogenicity. It is also important to protect the nucleic acids from degradation and large-scale production ca [...]

A Retrospective Study of Progressive Gait Impairment in Alzheimer’s Disease

Received: 27 December 2021;  Published: 08 September 2022;  doi: 10.21926/obm.geriatr.2203203

Abstract

Individuals with Alzheimer’s disease (AD) and Mild Cognitive Impairment (MCI) have increased gait disturbances throughout disease progression. However, an understanding of gait impairment and progression in early versus late AD is lacking. Further, the longitudinal progression of gait impairment in AD as well as in those with MCI that transition to AD is lacking. Understanding gait pathology and progression of gait impairment is critical for implementation of strategies that could limit the high prevalence of gait [...]

Management of Calcareous Corneal Degeneration from Medication Washout to Corneal Transplantation. Case Series and Review of the Literature

Received: 27 February 2024;  Published: 07 June 2024;  doi: 10.21926/obm.transplant.2402218

Abstract

Calcareous corneal degeneration is a rare disease characterized by calcium phosphate deposition into the deep corneal layers. Corneal calcification has a multifactorial origin and is associated with various systemic and ocular conditions. Several treatment options showed promising results in the management of this disorder. Herein, two cases of calcareous degeneration occurring postoperatively in patients undergoing surgery for retinal detachment (case #1) and glaucoma (case #2) were reported. Despite normal serum [...]
