(1) Background: The article provides insight into the mode of the immune system acting hierarchically when administering potentized remedies. Occasionally, this can be best seen in severe cases as available with cancer. (2) Methods: The careful anamnesis and subsequent prescription is based on Jan Scholten’s hierarchic classification of homeopathic mineral remedies. (3) Results: In such cases we find syndrome shifts of symptoms shifting from vital to less vital organs, from inside outside and from up downwards, e [...]

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 [...]

Electrical Submersible Pumps (ESPs) are one of the most widely used artificial lift methods in the petroleum industry. However, ESP failures are unanticipated and common occurrences with significant financial impacts for the operators. Analysis of the ESP performance and failures are essential in its design and optimization. This paper presents a statistical approach for diagnosing and evaluating the root causes of ESP failures. The analysis is based on the field data gathered from the surface and downhole ESP moni [...]

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 [...]

A precursor CuO/ZnO/Al2O3 catalyst for methanol synthesis has been prepared at room temperature by introducing a ternary salt solution into the excess of sodium carbonate solution following the reverse co-precipitation method. The catalyst was tested for the synthesis of methanol from synthesis gas. The composition (vol. %) has been presented: CO, 22; CO2, 5.8; N2, 5.5; H2, balance. The methanol productivity was recorded to be 2.7 kg kgcat–1 h–1 at a temperature of 260 °С, a pressure of 3 MPa, and a [...]

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 reverse mode polymer dispersed liquid crystal (PDLC) is an emerging smart window technology. Unlike traditional PDLCs, a reverse mode PDLC can be transparent and opaque in the absence and presence of an external electric field. This report provides a brief introduction to several reverse modes PDLC smart window technologies, focusing on polymer-stabilized liquid crystals (PSLCs). The systems based on electrohydrodynamic instability (EHDI) of liquid crystals have also been discussed. The working principles, mode [...]

Enzymes are extensively used in biotechnological processes in several areas of industry. They are sustainable and safe, and their specificity is another characteristic that improves the performance in the process. Among enzymes, lipase is relevant due to the ability to play different roles in the industry and the possibility of collecting them from microbial sources that are found in industrial residues. This can reduce the costs of enzyme production. In relation to that, lipase immobilization is an interesting pro [...]

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 [...]
