Computational Analysis Of A Single Air Bubble Rising In Quiescent Water Under Temperature Variations, Mokdad Hayawi Rahman, Muna Khalil Shehan, Emad Qasem Hussein, Farhan Lafta Rashid Jun 2026

Computational Analysis Of A Single Air Bubble Rising In Quiescent Water Under Temperature Variations, Mokdad Hayawi Rahman, Muna Khalil Shehan, Emad Qasem Hussein, Farhan Lafta Rashid

Al-Farahidi Expert Systems Journal

Two-phase fluid flow is widely encountered in petroleum, chemical, nuclear, and energy applications. Computational fluid dynamics (CFD) by ANSYS Fluent 17.2 has been employed in this work to simulate the rise of a single air bubble through stagnant water at different temperatures (0 °C, 25 °C, and 50 °C). In addition, a user-defined function(UDF)was developed and implemented to incorporate phase-change behavior and temperature-dependent properties. This study investigates how the buoyancy-driven bubble dynamics will be responsive to changes in liquid viscosity, surface tension, and density. The results demonstrated that increasing the temperature of water enhances the bubble rise velocity significantly; the …

Enhancement Of Mechanical Properties In 7050 Aluminum Alloy Using Zirconia Nanoparticle Reinforcements, Ahmed A. Ebraheem, Tahseen F. Abbas, Talib A. Jasim Jun 2026

Enhancement Of Mechanical Properties In 7050 Aluminum Alloy Using Zirconia Nanoparticle Reinforcements, Ahmed A. Ebraheem, Tahseen F. Abbas, Talib A. Jasim

Al-Farahidi Expert Systems Journal

Aluminum metal matrix composites (AMMCs), particularly those reinforced with ceramic nanoparticles, are critical materials for aerospace, automotive, and defense applications due to their superior strength-to-weight ratio. This study investigates the effect of zirconia (ZrO2) nanoparticles on the mechanical properties of a 7050 aluminum alloy matrix. Composites were fabricated via the stir-casting technique with ZrO2 reinforcements incorporated at varying weight fractions (0, 1, 2, 3, and 4 wt.%). A comprehensive mechanical characterization was conducted, evaluating hardness, tensile strength, and surface roughness. The results demonstrate that the inclusion of ZrO2 nanoparticles significantly enhances all measured properties. Hardness increased …

The Layered Knowledge Profile, Harendra A. Alwis Mr. Jun 2026

The Layered Knowledge Profile, Harendra A. Alwis Mr.

Defensive Publications Series

The Open Knowledge Format (OKF) gives the world a portable, vendor-neutral envelope for knowledge — markdown files with YAML frontmatter, cross-linked into a graph — and, by deliberate design, declines to specify how the knowledge inside that envelope should be organised, requiring only a single type field and defining the interoperability surface rather than the content model. The Layered Knowledge Profile (LKP) supplies the content model that OKF leaves open. It encodes, as machine-readable structure expressed entirely within OKF's own conventions, the asymmetric ontological dependency among the four realms of reality described by Alwis (2026), so that a body of …

Engineering Evaluation Of Post-Stroke Gait Using A Wearable G-Walk Sensor Under Different Ankle-Foot Orthosis Conditions: A Longitudinal Case Study, Mohamed Sattar Jabbar, Ammar Issam Kubba Jun 2026

Engineering Evaluation Of Post-Stroke Gait Using A Wearable G-Walk Sensor Under Different Ankle-Foot Orthosis Conditions: A Longitudinal Case Study, Mohamed Sattar Jabbar, Ammar Issam Kubba

AUIQ Technical Engineering Science

The gait profile of post-stroke patients is typically one of reduced speed, asymmetry and decreased functional mobility. Ankle–foot orthoses (AFOs) are commonly prescribed to enhance gait stability and promote safer ambulation; however, within-person longitudinal gait changes across multiple orthotic conditions have not yet been quantitatively characterized using wearable motion analysis systems. The objective of this study was to perform a longitudinal assessment of spatiotemporal gait parameters through a wearable G-Walk inertial measurement unit (IMU) with three walking conditions: without orthosis, Conventional custom-made ankle foot orthosis AFO and Prefabricated posterior leaf spring AFO. Two functional tasks, normal walking and Timed Up …

"They Will Put You Out Of The Synagogues”: An Exegesis Of John 16:1-4a And Its Application To The Persecuted Christians In Northern Nigeria, Chiemeka Iwuagwu Jun 2026

"They Will Put You Out Of The Synagogues”: An Exegesis Of John 16:1-4a And Its Application To The Persecuted Christians In Northern Nigeria, Chiemeka Iwuagwu

Obsculta

This paper offers an exegesis of John 16:1-4a, a pivotal passage in Jesus' Farewell Discourse that warns the disciples of impending persecution, including expulsion from synagogues. Situating the text within the historical and literary context of the Johannine community, it explores how this forewarning reframes suffering as an integral aspect of faithful witness rather than divine abandonment. Drawing on key scholarly works, the analysis engages literary structure, historical reconstruction of community experiences, and theological motifs such as dualism and Christology. The paper then applies these insights to the plight of Christians in northern Nigeria, a region marked by violent persecution, …

Developing Robust Human Formation For Ministerial Training, Mary L. Parks Jun 2026

Developing Robust Human Formation For Ministerial Training, Mary L. Parks

Obsculta

The Apostolic Exhortation Pastores Dabo Vobis recognizes that effective ministerial formation is holistic, attending to all aspects of a minister’s being. The document therefore outlines four pillars of formation: human, spiritual, intellectual, and pastoral. In Co-Workers In the Vineyard of the Lord, the United States Conference of Catholic Bishops (USCCB) extends the same four pillars of formation to the development of lay ecclesial ministers. The USCCB also applies these pillars to diaconal formation in The National Directory for the Formation, Ministry, and Life of Permanent Deacons in the United States of America.

The Incomprehensible God Who Wants To Reveal: Exodus 40 And Sirach 24, Gilbert Perez Jun 2026

The Incomprehensible God Who Wants To Reveal: Exodus 40 And Sirach 24, Gilbert Perez

Obsculta

God's transcendence above everything is present in many theological traditions, who recognize and answer in a diverse number of ways the question of how to approach the incomprehensible. Using the Historical Critical Method of exegesis with examples from the works of the recently deceased Walter Brueggemann, two completely different contexts in the Old Testament: Exodus 40 and Sirach 24, are presented to show how scripture itself often responded to the question of how God is made comprehensible.

I Cry At Night Before You: Theologies Of Depression In The Psalms, Travis Spillum Osb Jun 2026

I Cry At Night Before You: Theologies Of Depression In The Psalms, Travis Spillum Osb

Obsculta

This work looks to the Psalms to discover theologies that resonate with experiences of depression. If one struggling with depression feels as if God is angry with them, that their condition is oppressing them, that loved ones have abandoned them, or that God's love for them is wavering, they can utilize the psalmist's words to voice their feelings and express their anguish in prayer to a God who is seemingly deaf to their groaning.

Fulfilled In Your Hearing: What Has Been Fulfilled; What Remains To Be Heard, William Skudlarek Osb Jun 2026

Fulfilled In Your Hearing: What Has Been Fulfilled; What Remains To Be Heard, William Skudlarek Osb

Obsculta

This article reflects on the enduring legacy and contemporary relevance of Fulfilled in Your Hearing, the 1982 U.S. bishops’ official statement on the Sunday homily. Written by the document’s principal drafter, the piece explores the text’s revolutionary methodological shift: moving the starting point of preaching away from the preacher or the isolated text and toward the assembly gathered for Eucharist. The author argues that the homily is not an exegetical lecture or a discourse on morality but a sacramental interpretation of human existence through the lens of Scripture that calls the assembled worshippers to conversion, thanksgiving, and service. Central to …

Paul: A Man Called To Reform Status: The Radical Practice Of “One In Christ”, Garrett S. "Faustino" Miller Jun 2026

Paul: A Man Called To Reform Status: The Radical Practice Of “One In Christ”, Garrett S. "Faustino" Miller

Obsculta

This paper explores Saint Paul's ministerial pedagogy as he challenged Roman social hierarchies by calling believers to a radical unity as "one in Christ." By examining what this radical practice means, and what it is rooted in, this paper also urges readers toward the same radical and transformative vision of Christian oneness; a vision that seeks to build bridges rather than walls in the world today.
