Suggested Methods To Solve The Coils Misalignment For The Biomedical Implants, Saad Mutashar

Engineering and Technology Journal

One of the major problems of the inductive coupling link in the biomedical implantable devices is the misalignment between coils. This paper produces two simple suggested methods to avoid and reduce the misalignment between two coils. The first one is to split the implanted coil into two identical coils with 450 μH of inductance where the external coil was equal to them in inductance ~ 900μH.  The results show that the received powers are constant and compensated by one of the coils, which provides a stable power at the implant. The second proposed suggestion is to use two separated identical …

The Influence Of Exercise On Cardiometabolic Risk In Perimenopause: A Systematic Review, Bibha Gautam, Deborah J. Clegg, Mary Madeline Rogge, Jeni Page

International Nursing Research Congress (INRC)

Purpose: Perimenopause is a biologically vulnerable period characterized by hormonal fluctuations, visceral fat accumulation, and increasing insulin resistance, factors that elevate cardiometabolic risk and contribute to the development of cardiometabolic syndrome (CMS), defined as the presence of three or more metabolic abnormalities. These changes reflect a continuum of metabolic vulnerability that may emerge before CMS becomes clinically detectable. Although regular exercise can mitigate this risk, limited evidence clarifies which exercise modalities are most effective in reducing metabolic risk and CMS prevalence among women undergoing the perimenopausal transition. Despite facing a distinct and often underrecognized vulnerability to CMS, perimenopausal women remain …

Non-State Actors And The Due Diligence Obligation To Protect Healthcare Facilities In Cyberspace: Is The World Prepared For The Next Pandemic?, Dr. Ardit Memeti

Geopoetics: Expanding The Philosophy Of Teacher Education, Linda M. Craig Dr

Journal of Contemplative and Holistic Education

Amidst our accelerating ecological crisis, this essay argues for a fundamental reimagining of teacher education through Kenneth White's theory of geopoetics. Drawing on complexity science and Whitehead's process philosophy, I trace a paradigm shift from mechanistic models of education - characterised by fixed knowledge transmission and neoliberal performativity - toward a relational, orientation grounded in emergence and becoming. Geopoetics offers a transdisciplinary framework that dissolves boundaries between science, poetry, philosophy, and spirituality, positioning education not as content delivery but as participation in the creative unfolding of life. Through an exploration of Nan Shepherd's The Living Mountain as geopoetic spiritual practice. …
