Technical Disclosure Specification: Eliminating Late-Time Logarithmic Thermal Drawdown In Closed-Loop Geothermal Wells Via Soliton-Induced Boundary Layer Disruption, Christopher L. Eckes

Defensive Publications Series

This specification formalizes an advanced multi-physics engineering framework to eliminate late-time logarithmic thermal drawdown, localized stagnant fluid insulation, and long-term thermodynamic extraction decay in deep, closed-loop geothermal wells. Traditional geothermal energy extraction architectures encounter a severe physical limitation over extended operational runtimes: the continuous circulation of working fluid rapidly cools the immediate borehole rock face, establishing a stagnant thermal boundary layer that isolates the fluid from the core geological heat source and collapses extraction efficiency.

This framework resolves this bottleneck by treating the borehole rock-fluid interface as an active 2D viscoelastic fluid transport membrane operating at a strict coordinate baseline …

Selenoprotein P And Selenium As Potential Diagnostic Biomarkers For Breast Cancer Patients, Farah A. Rashid, Rawaa A. Ali, Hanaa A. Ali

Karbala International Journal of Modern Science

Breast cancer incidence increases in last decade. Oxidative stress increases during cancer development causes consuming of antioxidants. Selenium and its transporting protein, selenoprotein P have an important role in redox homeostasis. This study aims to investigate whether or not selenium and selenoprotein P could be diagnostic biomarkers for breast cancer patients. This study was included 30 individuals in control group who is age- and BMI-matched with 60 breast cancer patients. Selenium was measured by colorimetric assay kit and selenoprotein P was determined by Sandwich ELISA kits. The results indicate significant decrease (p < 0.0001) of serum selenium and selenoprotein P in breast cancer patients compared to control. A positive significant correlation (r = 0.6214, p < 0.0001) was found between selenium and selenoprotein P in breast cancer patients. Selenium has an excellent diagnostic accuracy with area under curve 0.9831, sensitivity 95% and specificity 100% at cut-off less than 3.54 mmol/L. Furthermore, selenoprotein P has also an excellent area under curve 0.9958 with sensitivity 96.77% and specificity 100% at cut-off less than 4.15 ng/ml. These exploratory findings appear that selenium and selenoprotein P could be potential diagnostic biomarkers for breast cancer patients. Further investigations in large-multicenter populations are needed to confirm results.

Mathematically Driven Enhancement In Information Security, Suhaib Badran, Asmaa Alqassab

Karbala International Journal of Modern Science

A new mathematically based cryptographic method has been proposed to improve information security; it involves transforming data into a matrix and performing bit-level operations. This decryption then follows the basic mechanism of a deterministic, fully invertible algorithm, with this invertible algorithm having the same principle as the existing ones: the process of decryption is symmetrical, where the process is reversed based on the input of the ciphertext. The plaintext is transformed into a square matrix, which includes matrix rotation, permutation of rows, circular bit shifting, and finally an affine linear transformation followed by an additional Base62-like encoding layer to further …

Murder Of A Creative: Mfa Thesis, Himani Sanjeevkumar Mehta

Masters Theses

In the creative industry, the phrase “fast-paced environment” is often treated as an essential ingredient for productivity and success. The contemporary design landscape operates within an output-driven system that prioritizes speed, visibility, and measurable worth, contributing to the growing commercialization of creativity. Within this framework, the creative process is often diminished or overlooked where it no longer serves efficiency, reducing creativity to a consumable outcome rather than a reflective and sustaining practice. As a result, creative professionals and students increasingly experience creative anxiety, burnout, and paralysis, alongside imposter syndrome, perfectionism, and self-doubt. These conditions are rarely examined as systemic outcomes …

Constructing Authority: Narrative Craft And The Making Of Meaning In Creative Nonfiction, Lindsay Erin Hickman

Masters Theses

What is this world without stories? Without truth and the sharing of knowledge for those that come after us? As a Christian, I see the Bible as the most influential narrative in my life and imagination. The Bible is filled with facts, lists and information we can verify, but that does not make it any less creative. How can one read the Bible and not see God’s creativity not only in creation, but in every word? Psalms 139: 13-15 states, “For thou hast possessed my reins: thou hast covered me in my mother's womb. I will praise thee; for I …

Is Genuine Redemption Possible Through A Counterfeit Christ?, Tams M. Mullins

Masters Theses

Members of The Church of Jesus Christ of Latter-day Saints (LDS), commonly referred to as Mormons, consider themselves Christians without equivocation. Evangelical Christianity has, however, challenged this claim since the inception of the Latter-day Saints. The Latter-day Saints purport to be Christian in doctrine and practice and claim a Christian identity centered around their acceptance of the death, burial, resurrection, and ascension of Jesus Christ. While the Latter-day Saints ascribe to a high Christology, confess Jesus as Lord, and regard Him as their Redeemer, the Jesus of the Latter-day Saints’ literature bears little resemblance to the Jesus of evangelical Christianity. …

Slowing Down With The Archives: Reexamining An Archaeological Context From Pre-Columbian Coastal Ecuador, Madison Rieth

Electronic Theses and Dissertations 2020 - Present

Archaeological excavations leave behind extensive paper trails and repositories of materials.
