Contactless Detection of Natural Bending Frequencies using Embedded Metallic-Glass Ribbons inside Plastic Beams made of 3-D Printing

Received: 12 December 2020;  Published: 06 April 2021;  doi: 10.21926/rpm.2102010

Abstract

In the current work, to identify the bending mode harmonics, 30 microns thin magnetoelastic ribbons made of metallic glass are embedded inside 6 mm thick PLA plastic cantilever beams made by 3-D printing. This is possible because the ribbons are of magnetoelastic nature and thus change their mechanical state inducing a corresponding change in their magnetic state. The ribbons are placed at four different depths, starting with zero depth at the beam’s external surface all the way inside to the beam’s mid-plane. This [...]

Combination, Sequential Therapies Incorporating Tocilizumab Decrease the Progression of Chronic Lung Allograft Dysfunction (CLAD) after Lung Transplantation: Initial Clinical Experience

Received: 19 September 2019;  Published: 07 November 2019;  doi: 10.21926/obm.transplant.1904090

Abstract

Introduction: TH-17 and IL-6 interactions and detrimental biologic effects have been shown in rodent models of Chronic Lung Allograft Dysfunction (CLAD). Similarly, these pathways have been found to be upregulated in human CLAD. Tocilizumab (TCZ), a humanized monoclonal antibody targets the IL-6 receptor subunit alpha and prevents binding of IL-6. We herein report our preliminary experience with adjunctive TCZ therapy for human CLAD. Methods: We retrospectively reviewed our initial experience with TCZ given after o [...]

Associations between Health-Related Behaviours, Well-Being, and Academic Performance of Secondary School Students with Special Educational Need: A Secondary Analysis

Received: 24 October 2022;  Published: 06 March 2023;  doi: 10.21926/rpn.2301005

Abstract

Health-related behaviours (HRBs) have been considered one of the most critical public health issues, especially for those with special educational needs (SEN). Previous research suggests that health-related behaviours are highly likely to impact well-being and academic achievement. Diet is a crucial health-related behaviour that needs to be investigated along with factors such as sleep and exercise. The present study used data from the Cornish Academies Project, and secondary analyses were conducted to investigate [...]

The Role of Telomeres in Senescence, Aging and Disease: Fiction and Reality

Received: 21 May 2025;  Published: 09 September 2025;  doi: 10.21926/obm.geriatr.2503324

Abstract

Telomeres are repetitive structures at the ends of linear chromosomes. Due to incomplete DNA replication at the end of linear DNA molecules, the so called “end replication problem”, telomeres shorten consecutively during cell division. In addition, telomere sequences are highly susceptible to oxidative stress damaging telomeres and resulting in their dysfunction even in non-dividing cells. Telomere shortening has been identified as one of the underlying causes for replicative senescence that can also contribute to [...]

Influence of Recycled Concrete Aggregate Type on Rheological Behaviour of Mixtures Proportioned Using the Equivalent Volume Method

Received: 11 July 2022;  Published: 07 September 2022;  doi: 10.21926/rpm.2203017

Abstract

The ever-growing urgency to combat climate change has led the civil construction industry to develop and adopt sustainable construction materials and methods. The so-called recycled concrete aggregate (RCA) emerges as an alternative to decrease the carbon footprint of new concrete construction, the disposal of waste concrete, and the use of non-renewable natural resources such as cement and aggregates. RCA can be produced from crushing waste concrete; yet challenges remain when using RCA in concrete especially its [...]

Graphene Quantum Dots from Synthesis to Innovation for Advanced Optics and Bio-Optics Trends

Received: 24 November 2024;  Published: 18 February 2025;  doi: 10.21926/rpm.2501007

Abstract

The generation of non-classical light with improved performances within tiny sizes, intervals of lengths, and diameters is still a challenge. The generation of variable wavelengths associated with different frequencies of energy modes produced from new sources of emitters within confined scales from the Quantum to Nano-and Micro-scales are of high impact. It is noted here that the concept of the generation of non-classical light related to electronics and photonics interactions with different topological matter con [...]

Automated Probabilistic Analysis and Parametric Modelling of the Seasonal-Diurnal Wind Vector

Received: 14 April 2021;  Published: 25 June 2021;  doi: 10.21926/jept.2102027

Abstract

A refined and extended version of the Offset Elliptical Normal mixture model has been developed to parameterise the seasonal diurnal wind vector automatically. Automated using R scripts, the method eliminates any potential risk of confirmation bias posed by the manual supervision in the original method. Refinements to the method include the latest algorithms for clustering of Gaussian mixtures, with Bayesian regularisation to set the number of components and to limit the predisposition to overfit. A new extension u [...]

The Use of Sulfur Waste to Protect Against Corrosion of Metal Implants

Received: 24 March 2021;  Published: 15 June 2021;  doi: 10.21926/rpm.2102024

Abstract

Metal parts of endoprosthesis have a detrimental effect on the bones that come into contact with them and on the entire body of the patient. Coating them with biocompatible layers (hydroxyapatite and bioglass) has not yet brought about permanent results. In this study, the author showed the possibility of using a binder containing sulfur waste for this purpose. The sulfur binder is used industrially in electrical engineering and construction applications. The chemical properties of elemental sulfur indicate that it [...]

An Unusual Case of Recurrent Capillary Leak Syndrome Following Lung Transplantation

Received: 24 April 2020;  Published: 15 June 2020;  doi: 10.21926/obm.transplant.2002113

Abstract

Systemic capillary leak syndrome is a disorder characterized by recurrent, life-threatening episodes of acute capillary hyperpermeability resulting in edema and hypovolemic shock. We report a case of systemic capillary leak syndrome in a lung transplant recipient who developed recurrent episodes of volume overload, respiratory failure, and acute kidney injury in association with hypotension and hypoalbuminemia. Initiation of monthly high dose intravenous immunoglobulin prophylaxis effectively abrogated the syndrome [...]

Experience with Active Learning: The Charleston, SC, USA Urban Heat Island Effect

Received: 11 February 2022;  Published: 07 May 2022;  doi: 10.21926/aeer.2202020

Abstract

The urban heat island (UHI) effect is not well understood, especially within the cityscape. This editorial is from the perspective of an undergraduate student Cadet Emma Larsen, as she comes to understand the UHI through mentorship from professors Simon Ghanat and Scott Curtis, personal experiences as a cadet at a military academy in Charleston, SC, USA, and active learning through participation in a national heat observation campaign, the NOAA HeatWatch, and related independent research. HeatWatch seeks to underst [...]
