Stability Analysis of Autonomous Microgrid Operated at Constant-Frequency with the Consideration of Reactive Power Balance

Received: 01 September 2023;  Published: 29 November 2023;  doi: 10.21926/jept.2304039

Abstract

Large-scale autonomous microgrids have potential application values as they can increase renewable energy penetration level without compromising the stability of the existing large power systems. Before their widespread implementation, critical issues like stability analysis etc need to be solved. This paper analyses the stability in an autonomous microgrid operated at constant frequency with the consideration of reactive power balance. Difference equations of reactive power for the grid-forming generator are const [...]

Interactive Technology to Help People with Multiple Disabilities Practice Relevant Physical Responses within an Occupational Task

Received: 09 October 2023;  Published: 02 January 2024;  doi: 10.21926/obm.neurobiol.2401203

Abstract

This study adapted a new interactive technology system to help six participants with intellectual disability and visual and motor impairments to exercise relevant physical responses as part of an occupational task. The task was to place objects into different containers from a sitting position. The responses, which changed across sessions, consisted of the participants (a) stretching the left arm and shoulder to place objects in a container located to their left, (b) stretching the right arm and shoulder to place o [...]

Frequency of Unplanned Readmissions Following Lung Transplantation During the SAR-COV-2 Pandemic When Hospital Resources Were Strained

Received: 19 October 2023;  Published: 08 May 2024;  doi: 10.21926/obm.transplant.2402214

Abstract

Despite the concerted efforts by lung transplant recipients (LTR) and their medical teams, hospital readmissions are common in the first year following transplantation. Reasons for unplanned readmissions include allograft rejection, infections, and respiratory failure before the SARS-COV-2 pandemic. Clinical predictors of readmissions have changed over time with the higher risk factors of acceptable criteria for recipients and donors. We aimed to assess more recent readmission rates based on group classifications t [...]

Catalytic Co-gasification of Lignites Blended with a Forest Residue under the Carbon Dioxide Stream

Received: 24 May 2022;  Published: 29 September 2022;  doi: 10.21926/cr.2203031

Abstract

The present study investigated the co-gasification of two different lignites blended with the forest residue collected from the land restoration activity sites of open-pit mines located in the region of the Ptolemais basin in North Greece performed under the carbon dioxide stream. All samples were devolatilized in a fixed bed unit prior to the gasification evaluations. The gasification evaluations were performed using a thermal analysis system (TG/DTG) operated at temperatures of up to 1000 °C. The reactivity, [...]

A Urinary Proteomics Approach to Predict Treatment Response in Acute Antibody-Mediated Rejection

Received: 12 July 2023;  Published: 25 September 2023;  doi: 10.21926/obm.transplant.2303196

Abstract

Acute antibody-mediated rejection (AMR) is a severe complication affecting kidney allografts' long-term survival. Timely detection and appropriate treatment of AMR are crucial for improving graft outcomes. This study aimed to discover non-invasive urinary biomarkers that can predict the response to therapy in patients with AMR. Materials and Methods: In this case-control study, urine samples from 21 biopsy-proven AMR patients underwent proteomics using label-free quantification. The patients were divided into two g [...]

Impact of Intravenous Immunoglobulin Replacement Therapy on Hypogammaglobulinemia and Infection in Lung Transplant Recipients

Received: 29 January 2024;  Published: 03 July 2024;  doi: 10.21926/obm.transplant.2403220

Abstract

Secondary hypogammaglobulinemia (HGG) from immunosuppression therapy in lung transplant recipients has been associated with increased mortality, morbidity and higher risk of infection. Intravenous immunoglobulin (IVIG) for the treatment of HGG post-lung transplant is not well studied with conflicting evidence regarding efficacy. This single-center, retrospective cohort study analyzed adult lung transplant recipients with HGG receiving ≥1 dose of IVIG 0.3-0.5 g/kg. Resolution of HGG (IgG > 600 mg/dL wi [...]

Peri-transplant Treatment with Ceftaroline in Kidney Transplant Recipients at Risk of Donor-derived MRSA Infections: A Case Series

Received: 19 July 2023;  Published: 01 November 2023;  doi: 10.21926/obm.transplant.2304200

Abstract

The rising prevalence of MDR pathogens has a significant impact on the recipients' outcome, as this increases the risk of graft complications and makes the management of the peri-transplant phase more difficult. Among the different MDR germs, Methicillin-resistant Staphylococcus aureus (MRSA) represents one of the most frequently isolated pathogens. We report for the first time the off-label use of Ceftaroline in six kidney transplant recipients with donor peritransplantation MRSA bacteremia at the Division of Kidn [...]

Cross-Temporal Patterns of Care Provision by Older Adults during COVID-19 Pandemic: Lessons for Resilience

Received: 13 March 2023;  Published: 11 July 2023;  doi: 10.21926/obm.geriatr.2303242

Abstract

The current study aimed to examine the link between cross-temporal patterns of care provision and loneliness in older adults. Social capital and caregiver stress perspectives served as a theoretical framework for the study. The data were obtained from the two COVID-19 waves of the Survey of Health, Ageing, and Retirement in Europe (SHARE) conducted in 2020 and 2021. The data were analyzed using logistic regression models. The analytical sample consisted of 48,722 older adults residing in Europe and Israel. The anal [...]

The Intra-Institutional Waste Management in Montevideo Healthcare Centers

Received: 23 September 2024;  Published: 20 May 2025;  doi: 10.21926/aeer.2502023

Abstract

Healthcare Waste (HCW) management is a pressing challenge in Latin America, where insufficient regulatory enforcement, poor segregation practices, and the lack of accurate generation data hinder sustainable waste management. This study presents a methodological proposal for the internal management of HCWs in Healthcare Centers (HCCs) in Uruguay, based on Decree 586/009 and developed through a situational diagnosis conducted at the Hospital de Clínicas "Dr. Manuel Quintela." The diagnosis involved the qualitative an [...]

Strength Properties of Cellulosic Fibrous Mats Impregnated with Water Repellents Based on Reclaimed Polystyrene

Received: 23 August 2022;  Published: 28 October 2022;  doi: 10.21926/rpm.2204022

Abstract

Cellulosic fibrous mats were impregnated with various water-repellent formulations based on reclaimed polystyrene (5, 10, 15, and 20%), alkyd resin (5%), gum rosin (5%), and paraffin wax (0.5%). The mats were tested for their bursting strength and resistance to bending. They were also subjected to the ring crush test and short-span compression test. By increasing the concentration of total solid ingredients (5, 10, 15, 20, and 25.5%), the retention and grammage of the mats were increased, and all strength propertie [...]
