Ocular Pressure-Volume Relationship and Ganglion Cell Death in Glaucoma

Received: 24 November 2020;  Published: 21 May 2021;  doi: 10.21926/obm.neurobiol.2102098

Abstract

We studied how GC death in glaucoma related to the intraocular pressure (IOP), eyeball volume (VS) and elasticity (volumetric KS and tensile ES), and eyeball volume-pressure relation. Glaucomatous GC loss was studied in DBA/2J (D2) mice with wild-type mice as controls. GCs were retrogradely identified and observed with a confocal microscope. The elasticity calculation was also done on published data from patients treated by a gas bubble injection in the vitreous cavity. The GC population in D2 mice (1.5- to 14-mont [...]

Active Aging for L.I.F.E.: An Intergenerational Program for Addressing and Changing Attitudes Toward Longevity

Received: 19 July 2022;  Published: 27 December 2023;  doi: 10.21926/obm.geriatr.2304264

Abstract

The global population of adults 65 years of age and older will increase dramatically over the next several decades, presenting economic and social challenges requiring sustainable solutions. Aging is a process in which everyone is already involved, it is a lifelong experience not just a later life occurrence. Changing world demographics illustrate that people are living longer, among the world’s young people, survival to age 80 is expected to be commonplace. This new found “longevity dividend” needs to be maximized [...]

Screening Before We Know: Radical Uncertainties in Expanded Prenatal Genetics

Received: 15 July 2021;  Published: 09 October 2021;  doi: 10.21926/obm.genet.2104140

Abstract

In this article, we discuss the radical uncertainties unleashed by expanded prenatal genetics. We show how we are now routinely screening fetuses in the absence of two essential sorts of information. At the population level, we do not have sound, unbiased data about the prevalence, penetrance, and clinical variability of most mutations. At the level of the proband, it is often too soon to discern relevant information about the fetus’ phenotype. First, we outline the longstanding ethical objections to newborn screen [...]

Acute Care Decision-Making for Patients with Advanced Dementia: An Exploratory Study Using Cognitive Task Analysis

Received: 11 November 2020;  Published: 01 March 2021;  doi: 10.21926/obm.geriatr.2101159

Abstract

Decision-making by medical and health care staff forms the core of professional practice. Thought processes, including non-clinical considerations, significantly impact how clinical decisions are made. Such considerations become more relevant when addressing end-of-life care decisions for patients with advanced dementia (PAD). Though palliative care is recommended for this population, its implementation tends to vary. Given the medical staff’s significant influence in guiding clinical decisions, we examined thought [...]

Burnout Among Special Education Teachers and the Role of Individual, Interpersonal, and Organizational Risk and Protective Factors

Received: 30 March 2023;  Published: 10 August 2023;  doi: 10.21926/obm.icm.2303033

Abstract

Burnout is a syndrome commonly characterized by the three dimensions of Maslach and Leiter's model, namely emotional exhaustion, depersonalization, and lack of professional accomplishment. While burnout affects individuals in all professions, teachers are recognized as being at particular risk, a fact explained in the literature by the high level of relational demands inherent to the profession. During the pandemic and subsequently, these demands have even increased. Several studies have focused on the influence of [...]

Reaction Kinetics and Characterization of Slag-Based, High Strength, “Just-Add-Water” Type (One-Part) Alkali-Activated Binders

Received: 03 February 2022;  Published: 08 April 2022;  doi: 10.21926/rpm.2202006

Abstract

The influence of different levels of alkalinity, expressed using M2O-to-binder ratio (n) and activator SiO2-to-M2O ratio (Ms), (M being the Na+ or K+ cation) on the reaction kinetics, compressive strength development and the reaction product formation in slag-based systems activated using alkali powders are discussed. The fundamental idea is to better understand one-part, “just-add-water” type alkali activated binders that are easy-to-use than the systems that rely on liquid activators. The difference in the behavi [...]

Recent Developments in the Application of Gallus domesticus Eggshells for the Biosorption of Dyes and Heavy Metals

Received: 29 July 2024;  Published: 28 November 2024;  doi: 10.21926/aeer.2404024

Abstract

Global efforts to develop low-cost solutions for the treatment of contaminants in wastewater continue unabated. The conversion of eggshells, a waste material, into a high-value product can be economical and environmentally sustainable. The recent developments in applying eggshells towards the biosorption of contaminants are presented. Eggshells effectively remove pollutants such as metal cations, metal anions, and reactive, basic, and direct dyes. Promising advances in modifying eggshells, elucidating the critical [...]

Design and Techno-Economic Evaluation of a Hybrid Mini-grid System for an Academic Institution

Received: 26 September 2023;  Published: 03 April 2024;  doi: 10.21926/jept.2402010

Abstract

Inadequate electricity supply is a global challenge that needs solutions. This situation has compelled the purchasing of fossil fuel-generating units for use in residential, commercial, and industrial sectors to generate electricity. However, using fossil fuel generating units cause greenhouse gas emissions, bringing about environmental pollution and ultimately resulting in climate change. In particular, educational institutions require adequate and reliable power supply to ensure proper learning and teaching, whic [...]

Significance of Insulation and Heat Pumps in Decarbonising the UK

Received: 09 November 2022;  Published: 09 January 2023;  doi: 10.21926/jept.2301003

Abstract

This paper examines the economic case for the UK to proceed urgently with the installation of thermal insulation and heat pumps in most UK buildings, in the context of the legal requirement to achieve net-zero carbon emissions by 2050. A recent study by the same authors assumed that such insulation and heat pumps would be in place, and showed how the whole of the UK’s energy demand could be met by low carbon electricity generation and appropriate storage. This paper extends the modelling to consider the risk that i [...]

Versatility of Supported Gold Nanoparticles on Hydrotalcites used for Oxidation and Reduction Reactions

Received: 25 October 2021;  Published: 13 January 2022;  doi: 10.21926/cr.2201001

Abstract

Regardless of their size, supported gold nanoparticles are largely used for liquid-phase oxidation reactions. Small gold nanoparticles exhibit good performance during the reduction of organic compounds. The direct reduction of carboxylic acid to aldehyde is a famous and familiar reaction in the field of organic chemistry and is considered as one of the fundamental chemical transformations. Herein, we present Au/hydrotalcite, Au/MgO, and Au/Al2O3 systems as heterogeneous versatile catalysts to realize the oxidation [...]
