Effects of Land Cover/Use Change and Altitude on Soil NPK Nutrients in Selected areas in the North West Region of Cameroon

Received: 29 September 2021;  Published: 30 December 2021;  doi: 10.21926/aeer.2104038

Abstract

Land-use change is one of the main indicators of soil quality. Soil physical and chemical properties vary with land use change and altitude as inferred from transect surveys and toposequences. Soil nitrogen, phosphorus, and potassium (NPK) are essential macronutrients for plant growth and soil nutrient balance. Their presence in the soil in appropriate quantities is important for maintaining crop yields and farmers income, particularly in developing countries where resources of soil chemical additives may be limite [...]

Neuronal Coherence Agent for Shared Intentionality: A Hypothesis of Neurobiological Processes Occurring during Social Interaction

Received: 02 October 2021;  Published: 29 December 2021;  doi: 10.21926/obm.neurobiol.2104113

Abstract

The present interdisciplinary study discusses the physical foundations of the neurobiological processes occurring during social interaction. The review of the literature establishes the difference between Intentionality and Intention, thereby proposing the theoretical basis of Shared Intentionality in humans. According to the present study, Shared Intentionality in humans (Goal-directed coherence of biological systems), which is the ability among social organisms to instantly select just one stimulus for the entire [...]

The Donor – Recipient Weight Ratio is a Reliable Marker for Cell Yield in Hematopoietic Stem Cell Donations

Received: 22 November 2021;  Published: 24 December 2021;  doi: 10.21926/obm.transplant.2104156

Abstract

Bone marrow transplants remain an import source of hematopoietic stem cells for patients suffering from specific diseases like aplastic anemia, for pediatric patients with malignant and non-malignant blood cell disorders, and for situations in which graft-versus-host disease (GvHD) is a concern. Identifying the optimal donor to achieve a 3-5 x 108/kg of recipient weight TNC yield may be challenging. In an analysis of 687 consecutive donors, donor and procedure characteristics were related to TNC/kg of recipient wei [...]

The Potential Impact of COVID-19 on Depression and Suicide Risk in Older Adults

Received: 19 January 2021;  Published: 24 December 2021;  doi: 10.21926/obm.neurobiol.2104112

Abstract

COVID-19 infections, hospitalizations, and deaths continue to skyrocket across the world, leaving a trail of enduring psychological turmoil. It wreaks havoc on the physical, emotional, and cognitive health of those directly infected, as well as caretakers, friends, and families. Though the pandemic has at least indirectly impacted most people, older adults appear to be the most vulnerable to COVID-19-related deaths and little is known about the psychological consequences. Unfortunately, many of the precautions take [...]

A System Dynamics Modelling Approach for Electronic Waste Recycling after Floods in Jakarta and New Orleans

Received: 15 October 2021;  Published: 23 December 2021;  doi: 10.21926/aeer.2104037

Abstract

Due to climate change, flood-related disasters are expected to increase. Floods generate enormous amounts of waste, including electronic waste (e-waste). E-waste should be recovered not only because it can have detrimental effects on human health and the environment but also because of the valuable metals contained in it. In this study, a system dynamics model based on current practices and waste management was established using Vensim to determine the revenue that can be generated by e-waste recycling after floods [...]

Adjustment for Covariates of Major Depressive Episodes among Men and Women Aged 65 Years Old and Older

Received: 17 August 2021;  Published: 22 December 2021;  doi: 10.21926/obm.geriatr.2104185

Abstract

The current study aimed to examine if sex can significantly predict risk for lifetime major depressive episodes among adults aged 65 and older with and without adjustment for covariate variables of race, education, marital status, health, and poverty. Secondary data was obtained from the National Survey on Drug Use and Health public-use data file to achieve study goals. The study participants were males and females aged 65 years or older. The unweighted sample included 3,969 adults aged 65 years or older, represent [...]

Harvesting the Potential of CO2 before it is Injected into Geological Reservoirs

Received: 28 October 2021;  Published: 22 December 2021;  doi: 10.21926/jept.2104050

Abstract

To store CO2 in geological reservoirs, expansion valves have been used to intentionally release supercritical CO2 from high-pressure containers at a source point to lower-pressure pipelines and transport to a selected injection site. Using expansion valves, however, has some shortcomings: (i) the fluid potential, in the form of kinetic energy and pressure which can produce mechanical work or electricity, is wasted, and (ii) due to the Joule-Thomson cooling effect, the reduction in the temperature of the released CO [...]

Mediterranean Cropping Systems: The Importance of Their Economic and Environmental Sustainability

Received: 08 July 2021;  Published: 21 December 2021;  doi: 10.21926/aeer.2104036

Abstract

The COVID-19 pandemic has drastically changed the lives of people, as well as the production and economic systems throughout the world. The flow of raw materials and products, the supply of labor and manpower, and the purchasing power have all been changed to the detriment of individual health and well-being. Such a situation requires placing even more emphasis on the search for virtuous agricultural systems compatible with the goals of economic and environmental development so clearly defined at the world level in [...]

Developing Self-Compassion Online: Assessing the Efficacy and Feasibility of a Brief Online Intervention

Received: 21 September 2021;  Published: 21 December 2021;  doi: 10.21926/obm.icm.2104056

Abstract

The aim of the study was to assess the efficacy and feasibility of a newly designed online self-compassion training programme for the general public. Two hundred and forty-nine participants were randomly assigned to have either immediate or delayed access to a four-week online self-compassion training programme. This programme was based on Compassionate Mind Training and was made up of psychoeducational sessions and in-between session practices and readings. Out of the 179 participants who completed the pre-interve [...]

Cradle-to-Grave Life-Cycle Assessment of Cellulosic Fiberboard

Received: 24 August 2021;  Published: 21 December 2021;  doi: 10.21926/rpm.2104049

Abstract

According to the United Nations Environment Programme (UNEP), the construction and operation of buildings accounted for nearly 38% of total global energy-related CO2 emissions in 2019. The construction sector has been striving to use more low-carbon footprint building products to mitigate climate change and enhance environmentally preferable purchasing. Over the last several decades, there has been substantial growth in engineered wood products for the construction industry. To assess these products used in constru [...]
