Background: In the international auriculotherapy practice there are relatively big differences in the exact localization of the same ear acupuncture point. On one hand, there are specialists who devote their efforts to find the active points. In that case it becomes intriguing that there may be another point (at 1-2 mm distance) near the point to be treated, indicating a relatively strong, even stronger activity than the one they were initially aiming to find. That point may be active because of another health prob [...]

The point of zero charge (PZC) is an inherent electrokinetic property of biochars (BC). It influences the adsorption process under certain pH conditions. Herein, we report the method of determination of the PZC values of ten standard BCs. We used the salt addition method to select the BCs with suitable properties for methylene blue (MB) removal from aqueous solutions. The standard BCs were obtained by pyrolyzing five different biomasses at two distinct temperatures (550°C and 700°C). The BCs derived from rice husk [...]

Does compassion itself benefit the healing process or does the activation of neurophysiological processes, from which the experience of compassion arises, trigger a cascade of physical and psychological changes that support health and well-being? Exploration of the neurological substrates of compassion reveals multiple healing pathways that can be activated by mind-body practices. Furthermore, these pathways affect physical health, emotion regulation, and how we perceive and relate to others. Physiological states a [...]

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 [...]

The 19th century saw an explosion of serious epidemic diseases, such as smallpox and scarlet fever, which led to the development of an alternative system of medicine called homeopathy. Under this system, S. Hahnemann developed a rigorous methodology based on repeated observations on the field, leading to successful results. The aim of this work is to depict the birth and evolution of his thought. The correct understanding and application of this methodology became the reference model for subsequent generations of h [...]

The use of per-and poly-fluoroalkyl substances (PFAS) has resulted in the contamination of different environmental matrices. In EU countries, the sites contaminated with PFAS are usually remediated by excavating the soil and disposing of it in a landfill, as no in-situ or on-site techniques capable of treating large quantities of soil cost-effectively have been developed. Landfilling of PFAS-contaminated soil is one of the sources of PFAS in landfill leachate. In this paper, the physical and chemical treatment meth [...]
