Determining the Band Alignment at the BiVO4|NiOOH Interface Using the Hybrid DFT Technique

Received: 29 November 2021;  Published: 21 February 2022;  doi: 10.21926/cr.2201005

Abstract

It is important to understand the band offsets between semiconductors, which are crucial to determine the direction of electron transfer at the interfaces. Two methods are normally used to determine the direction from the first principles: alternating slabs put in contact (without empty spaces between them) and separate calculations for each material surface in the presence of vacuum spaces. The first method may introduce distortions due to insufficient epitaxial match, which may lead to bandgap changes, and the se [...]

Volt-Var Control for Utility-Scale Solar PV Plants to Downsize SVCs and Curtailment Effects

Received: 09 March 2023;  Published: 03 August 2023;  doi: 10.21926/jept.2303026

Abstract

One way to increase solar photovoltaic penetration in the grid is the management of voltage fluctuations. This is because a photovoltaic plant cannot be interconnected to the grid if it causes voltage violations. Voltage violation is where voltage exceeds the acceptable range. Often, grid operators request photovoltaic plant owners to regulate voltage sufficiently with expensive and space-consuming static Var compensators. Unfortunately, this sometimes makes the project less feasible. This paper argues that there a [...]

Umbilical Cord Blood as an Alternate Donor Sources for High Risk Elderly Patients Undergoing Allogeneic Stem Cell Transplantation for Hematological Malignancies

Received: 04 November 2020;  Published: 07 February 2021;  doi: 10.21926/obm.transplant.2101136

Abstract

Allogeneic stem cell transplantation remains the only curative option for many hematological malignancies. Umbilical cord blood (UCB) is an alternate donor source with potentially increased morbidity in elderly patients. We evaluated outcomes in alternate donor sources, prior to the initiation of haploidentical transplantation at our institution, of matched unrelated donor (MUD) and UCB in elderly patients (mean age 64, range 60-75). One hundred and eighty-four patients were included (MRD: 57; MUD: 69; UCB: 58). Th [...]

Does a Brief Mindfulness Training Enhance Heartfulness in Students? Results of a Pilot Study

Received: 24 May 2019;  Published: 10 October 2019;  doi: 10.21926/obm.icm.1904059

Abstract

Background: There is robust evidence that mindfulness trainings enhance mindfulness as operationalized in Western psychology, but evidence about their effect on aspects of heartfulness is sparse. The present study, therefore, sought to evaluate whether a brief mindfulness training enhances heart qualities, including self-compassion, gratitude, and the generation of feelings of happiness. Methods: Eighteen students enrolled in a mindfulness training that was offered as part of an interdisciplinary class. The trainin [...]

Older People and the Construction of Virtual Identities in the Digital Culture

Received: 06 February 2023;  Published: 10 May 2023;  doi: 10.21926/obm.geriatr.2302235

Abstract

This research study addresses certain theoretical issues surrounding the relationship between digital technologies, the aging population, and identity. At the same time, it offers a conceptual proposal of indicators of the social inclusion of older people in the digital culture of society as a potential starting point for further empirical research. The progressive trend of a growing proportion of older people is a demographic reality in many economically and technologically advanced societies. This demographic agi [...]

Runs of Homozygosity and Epigenetic Deregulation of Genomic Imprinting

Received: 29 May 2018;  Published: 15 August 2018;  doi: 10.21926/obm.genet.1803028

Abstract

Runs of homozygosity (ROH) are uninterrupted contiguous regions within the genome exhibiting allelic homozygosity (alleles are inherited from the same parent). Genome-wide analyses consistently demonstrate that megabase-scale ROH are ubiquitous in humans, reflecting individual demographic history. The number and length of ROH correlate increasingly with the degree of consanguinity and can be associated with genetic diseases in both inbred and outbred individuals. Genomic imprinting and uniparental disomy (UPD) are [...]

Kinetic Model for the Hydrolysis of Olive Oil by Lipase in Absence of Emulsifier

Received: 27 March 2024;  Published: 18 July 2024;  doi: 10.21926/cr.2403009

Abstract

Lipase-catalyzed hydrolysis of olive oil has been studied in the absence of emulsifier. A simple mathematical model to predict the hydrolysis rate is derived from a proposed kinetic mechanism of the reaction. The hydrolytic reaction obeys Michaelis-Menten kinetics with a simultaneous second-order enzyme deactivation. The model predictions closely agree with the experimental results.

A Participation-Focused Exercise Intervention for Children with Neurodevelopmental Disorders: Feasibility, Acceptability, and Impact on Sleep and Wellbeing

Received: 17 November 2020;  Published: 06 May 2021;  doi: 10.21926/obm.neurobiol.2102094

Abstract

Sleep-related difficulties are common in children with neurodevelopmental disabilities. Poor sleep health is associated with detrimental impacts not only for the child/young person, but also their family members. Exercise is considered to be important for sleep health, improving duration and quality of sleep in adult studies, however there is limited literature on impact in children with neurodevelopmental disabilities, and barriers to participation exist for this group. We set out to test the feasibility and accep [...]
