Mileva Radonjic

Received: 21 March 2022; Published: 29 April 2022; doi: 10.21926/aeer.2202017

Abstract

Oil and gas wellbores that are drilled into the earth’s crust need to be plugged and abandoned, to restore the geological seals once they are no longer producing. The main aim of Plugging and abandonment (P&A) is to ensure that there is no leakage of hydrocarbons into the environment. Since offshore P&A is challenging due to subsurface temperature and pressure conditions, testing zeolite as an additive for improvement of cement properties is an intriguing research topic. This initial research aims to [...]

Received: 29 January 2022; Published: 26 April 2022; doi: 10.21926/cr.2202012

Abstract

The use of the dry reforming of methane (DRM) to convert the two principal greenhouse gases, methane and carbon dioxide, to syngas (a mixture of H2 and CO) has attracted increasing attention in recent years. However, the DRM reaction suffers from the twin disadvantages of carbon deposition and sintering, so a highly efficient and robust catalyst with superior anti-deactivation properties is required. One way to meet this need is to incorporate active metals into crystalline oxides, such as perovskite. In this paper [...]

Abstract

Loneliness is a common condition that poses substantial risks to morbidity and mortality. Cacioppo and Cacioppo’s [1] evolutionary theory of loneliness (ETL) provides that loneliness serves a social signaling function and also manifests in hypervigilance to threat, which we propose can influence person perception. In this experiment, 480 observers evaluated videotaped self-presentation messages from speakers who scored either high or low on a measure of loneliness. On the basis of ETL, we hypothesized that observer [...]

Received: 27 January 2022; Published: 01 April 2022; doi: 10.21926/obm.icm.2202015

Abstract

The vague or controversial use of the term energy in the clinical subdiscipline known as "energy psychology" has been an obstacle to the field's acceptance. This paper discusses five forms of energy and explores the role of each in energy psychology treatments. While patterns in (a) electrical signaling, (b) brain waves, and (c) electromagnetic fields are presumably shifted in any form of effective psychotherapy, a strength of energy psychology interventions is shown to be in their ability to initiate such effects [...]

Abstract

Microwave-assisted extraction (MAE) to obtain phenolics from vegetable wastes has been of recent interest. Broccoli is one of the most globally produced vegetables, and around 43% of the harvest is considered waste. Thus, given the significant quantity of broccoli waste generated, the objective of this work was to optimize the MAE, to maximize the total phenolic content (TPC) from broccoli by-products (leaves and stems) and broccoli florets. The Response Surface Analysis was used in the optimization model to evalua [...]

Joseph S. D'Arrigo

Received: 08 December 2021; Published: 29 March 2022; doi: 10.21926/obm.neurobiol.2201117

Abstract

Cerebrovascular atherosclerosis, and several other cardiovascular (or "inflamm-aging" type) diseases, are more frequent and advanced in subjects with Alzheimer's disease compared with normal aging. In addition, the observed pathogenic link to dementia (and its associated cerebral microvascular damage) is readily explained by alterations of arterial elasticity. A therapeutic strategy to delay dementia could be based upon localized drug delivery, using lipid nanocarriers (i.e., biobased nanoemulsion technology), targ [...]

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

José C. Conesa

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 [...]

Abstract

Experimental phenomenology is the investigation of phenomenological practices and their effects. To engage in a phenomenological practice means to focus attention on aspects of one’s experiences (e.g., sense impressions or body sensations) while adopting a specific kind of attitude (e.g., an explorative attitude) according to some set of instructions. The basic assumption is that the regulation of attention and attitudes involved in such practices may have effects on people’s health and quality of life. The present [...]

How Might Changing Climate Limit Cyanobacteria Growth in Shallow Prairie Lakes? An Empirical Space-For-Time Evaluation of the Potential Role of Increasing Sulfate

Susan M. Joshi and

Leland J. Jackson

Received: 20 November 2021; Published: 15 February 2022; doi: 10.21926/aeer.2201007

Abstract

Cyanobacteria blooms alter aquatic ecosystems and occur frequently in shallow prairie lakes, which are predicted to increase in salinity as the regional climate becomes hotter and drier. However, flat landscapes that experience depression bottom salinity with high concentrations of sulfate in addition to sodium and chloride, may mitigate nutrient increases or even inhibit cyanobacteria growth. Cyanobacteria can dominate shallow lakes with low N:P ratios because many cyanobacteria species fix dissolved N2, whether d [...]
