An Overview of Treatments for Ultraviolet Quenching Substances (UVQS) and Per- and Polyfluoroalkyl Substances (PFAS) Removal from Landfill Leachate

Received: 15 September 2023;  Published: 24 January 2024;  doi: 10.21926/rpm.2401002

Abstract

Organics found in landfill leachate (humic acids, fulvic acids, and hydrophilic fraction) have a solid ability to absorb ultraviolet (UV) radiation, which negatively affects UV disinfection; leachate ultraviolet quenching substances (UVQS) can, therefore, have a significant impact on the cotreatment of landfill leachate and sewage in wastewater treatment plants. On the other hand, per- and polyfluoroalkyl substances (PFAS), which pose potential risks to the environment and human health, commonly exist in landfill l [...]

Cost-Effective Biodiesel Synthesis from Waste Marble Powder as A Green Heterogeneous Catalyst Using Pongamia Pinnata Oil

Received: 08 December 2022;  Published: 13 March 2023;  doi: 10.21926/cr.2301013

Abstract

Waste marble powder (WMP) is Investigated for developing heterogeneous catalysts by calcination method and used in biodiesel synthesis by esterification-transesterification process from Pongamia Pinnata oil. Hammet indicators, Fourier transform infrared (FT-IR), Thermogravimetric analysis, and X-ray powder diffraction (XRD) techniques were also studied for the characterization of developed catalyst from waste marble powder (WMP). The conversion of calcium carbonate to calcium oxide in marble powder was found at 800 [...]

Promoting Quality of Life in Advanced Dementia Care: Reading Buddies Program as Service-learning

Received: 08 February 2021;  Published: 30 April 2021;  doi: 10.21926/obm.geriatr.2102169

Abstract

The Reading Buddies Program was developed as a service-learning component of an Occupational Therapy Practice with Older Adults course as a collaboration between Tufts University and the VA Bedford Health Care System. The purpose of this service-learning program was to challenge graduate students’ implicit biases and improve communication skills when working with older adults with significant cognitive impairments. Through this collaboration, occupational therapy students provided individualized, activity-based car [...]

Correlation of Mutational Signatures in Cancer Genes with General Signatures

Received: 07 December 2021;  Published: 13 February 2022;  doi: 10.21926/obm.genet.2201147

Abstract

The occurrence of various mutation patterns, such as changes in the DNA sequence and the loss of some sequences, is called a “mutational signature,” and they represent the molecular fingerprints that exist for the type of mutation occurring in a specific gene. Our study elucidates the correlations of mutational signatures in frequently mutated cancer genes with general mutational signatures previously found for different cancers. We hypothesized that the top twenty most frequently mutated genes (MFMG) of a cancer t [...]

Conservation Prioritization of Ecologically Susceptible Zones at Disaggregated Levels

Received: 29 December 2021;  Published: 22 April 2022;  doi: 10.21926/aeer.2202014

Abstract

Ecologically susceptible zones (ESZs) are endowed with the distinct bio, geo, climatic, hydrological, and ecological integrity that sustain natural resources to support the livelihood of dependent populations. However, globalization and consequent anthropogenic activities have led to the erosion of the natural resource base and enhanced the levels of pollutants, triggering global environmental change, evident from changes in the climate. Alterations in the structure and the ecological integrity of ESZs may lead to [...]

Atrial Fibrillation, Anticoagulation, and Major Bleeding Episodes in Geriatric Patients at the Risk of Falling

Received: 22 May 2019;  Published: 26 August 2019;  doi: 10.21926/obm.geriatr.1903071

Abstract

Background: Geriatric patients are at risk of atrial fibrillation (AF) and stroke, and the risk of oral anticoagulation (OAC) related bleeding is also presumed to be higher. Detailed knowledge about the prevalence of AF and bleeding pattern in this population is scarce. This study sought to assess the prevalence of AF, use of OAC, and the rate of major bleeding in geriatric patients who are prone to frequent falls. We expect to find a higher prevalence of AF among geriatric patients compared to elderly people of co [...]

Organ System Bleeding in the PLADO Trial

Received: 30 December 2021;  Published: 26 April 2022;  doi: 10.21926/obm.transplant.2202158

Abstract

In the multi-institutional platelet dose trial (PLADO Trial), there were 1,077 hematology/oncology patients ≥18 years of age who received at least one platelet transfusion. These patients were analyzed for types and severity of organ system bleeding based on baseline patient characteristics, laboratory assays, primary diagnosis, and type of treatment. Patients were randomly assigned to receive one of three different prophylactic platelet doses for morning platelet counts of ≤10 × 109 /L. Daily assessmen [...]

Na+ Mobility in PEO-Based Composite Solid-State Electrolytes by NMR

Received: 04 August 2023;  Published: 02 November 2023;  doi: 10.21926/jept.2304032

Abstract

Charge transfer and mobility are essential for electrochemical processes in batteries, which need to be understood in detail for optimization, especially in the case of all-solid-state batteries. Wide line NMR is well-known in solid-state NMR and allows the quantification of ion mobility in ordered crystalline and amorphous structures. Temperature-dependent 23Na-NMR is sensitive to ion mobility via longitudinal relaxation, but also via line analysis and transverse relaxation. As 23Na is a spin 3/2 nucleus, 23Na-NMR [...]

Case Series of Multiple Health Benefits in Those Undertaking Extended Qigong Practice as a Complementary Self-care Practice in an Outpatient Pain Clinic

Received: 01 April 2019;  Published: 28 June 2019;  doi: 10.21926/obm.icm.1902040

Abstract

Background: Qigong, traditional Chinese mind-body practices, is currently receiving increasing attention with exploration of what it is and what it does. Common elements include postures and movement, attention to breathing, and mental instructions. There is a growing literature on the health benefits of qigong in chronic pain and other conditions, and an intervention that provides benefit in multiple domains is particularly important for clinical practice. In this report, we present a case series of six individual [...]

Happy and Satisfied in Very Late Life? Findings from the Health and Retirement Study

Received: 01 July 2022;  Published: 14 November 2022;  doi: 10.21926/obm.geriatr.2204211

Abstract

This research aims to examine cross-sectional and longitudinal associations of positive subjective well-being among centenarians and near-centenarians in the Health and Retirement Study. Participants who eventually survived to age 98 or older (N = 516) were included. Study variables included demographic characteristics, health and activities of daily living (ADL) functioning, cognitive functioning, and positive well-being. Additionally, a smaller subsample (n = 192) of participants with supplemental leave-behind qu [...]
