The Effect Of The Rate Of Strain On The Thermal And Mechanical Properties Of Al- 6030 Processed By Ecap., Maher Mohamed, Nader Nabil Zaafarani, A. E. Kabeel

Mansoura Engineering Journal

The function of severe plastic deformation (SPD) rate during equal-channel angular pressing (ECAP) on the thermal and mechanical characteristics of the aluminum alloy 6030 are experimentally investigated. ECAP was carried out at room temperature onto refining grain size for Al- 6030 of square cross-section specimens. The tests show that, for decreasing the rate of strain from 0.016 to 0.0023 s-1, the improvement in the hardness increases gradually until the highest value is reached at the rate of strain 0.004 s-1and decreases after that gradually. The percentage improvement in the hardness is around 68 % at the rate of strain 0.004 …

Caricom Caribbean’S Hrd 2030 Strategy: Inscribing The Neoliberal Imaginary Through Social Planning?, Nigel O.M. Brissett

Sustainability and Social Justice

The globalisation’s ‘knowledge economy’ has created a new set of human capital requirements. The guiding policy and planning document, The CARICOM Human Resource Development 2030 Strategy: Unlocking Caribbean Human Potential document, ‘serves as a roadmap for the CARICOM Caribbean’s responses to these human capital demands. I conduct a critical analysis of this document’s policy discourses to ascertain their core values and strategies, as well as their implications for the education and development of the CARICOM Caribbean. I find that the emergent discourses and ideas–neoliberal education reform and state-led social planning–provide a cautionary tale of the potential impact of educational change …

3d Permeability Characterization Of Sheared Fiber Reinforcement For Liquid Composite Molding Process Simulation, Collin William Childs

Theses and Dissertations

Resin transfer molding (RTM) is an infusion-based closed-mold manufacturing process where resin is injected into a preform of dry reinforcement to create a net shape part. Often, when a preform is draped over a mold with complex geometry, such as the double curvature of a dome, a reorientation of the fibers takes place in the form of in-plane shear. This deformation of the reinforcement structure has the potential to adversely affect the resin flow and the filling of the mold during RTM if the manufacturer fails to properly account for the shear effects. Various process simulation tools are being developed …

Partial Circuit Replication For Masking And Detecting Soft Errors In Sram-Based Fpgas, Andrew Mark Keller

Theses and Dissertations

Partial circuit replication is a soft error mitigation technique that uses redundant copies of a circuit to mask or detect the effects of soft errors. By masking or detecting the effect of soft errors on SRAM-based FPGAs, implemented circuits can be made more reliable. The technique is applied selectively, to only a portion of the components within a circuit. Partial application lowers the cost of implementation. The objective of partial circuit replication is to provide maximal benefit at limited or minimized cost. The greatest challenge of partial circuit replication is selecting which components within a circuit to replicate. This dissertation …

Department of Agricultural and Biological Systems Engineering: Faculty Publications

This study aimed to identify transcriptome differences between distinct or transitional stage spherical, ovoid, and tubular porcine blastocysts throughout the initiation of elongation. We performed a global transcriptome analysis of differential gene expression using RNA‐Seq with high temporal resolution between spherical, ovoid, and tubular stage blastocysts at specific sequential stages of development from litters containing conceptus populations of distinct or transitional blastocysts. After RNA‐Seq analysis, significant differentially expressed genes (DEGs) and pathways were identified between distinct morphologies or sequential development stages. Overall, 1898 significant DEGs were identified between distinct spherical and ovoid morphologies, with 311 total DEGs between developmental stages …

Thermal Transport To Impinging Droplets On Superhydrophobic Surfaces, Jonathan C. Burnett

Theses and Dissertations

An analytical model is developed to quantify the heat transfer to droplets impinging on heated superhydrophobic (SH) surfaces. Integral analysis is used to incorporate an apparent temperature jump at the superhydrophobic surface as a boundary condition. This Thesis considers the scenario of both isotropic and anisotropic slip, as would be realized on post-cavity style and rib-cavity style SH surfaces. This thermal model is combined with a hydrodynamic model which incorporates velocity slip at the surface. Use of the two models allows determination of the overall cooling effectiveness, a metric outlined in contemporary work. The effect of varying velocity slip and …

The Motivations Of Learning Foreign Languages: A Descriptive Case Study Of Polyglots, Noprival Noprival, Zainal Rafli, Nuruddin Nuruddin

The Qualitative Report

Polyglots are extraordinary people in terms of language ability. Therefore, it is interesting to academically explore their motivations for learning several languages. This research is novel compared to previous studies because scant extant research exists of polyglots’ motivation for learning several languages. To this end, researchers collected data from semi structured interviews obtained from five informants. The method that we used was a descriptive case study. Findings showed that the polyglots’ motivation for learning multiple foreign languages were (a) pleasure, (b) social intercourse, (c) professional purposes, and (d) academic purposes. Mostly, the previous research revealed that motivation for people learning …

Method For Creating Subject-Specific Models Of The Wrist In Both Degrees Of Freedom Using Measured Muscle Excitations And Joint Torques, Blake Robert Harper

Theses and Dissertations

Two-thirds of repetitive strain injuries affect the wrist joint. Although force is believed to be one of the major factors, the forces involved in wrist movements have not been thoroughly characterized in vivo. Computer simulations with a musculoskeletal model of the wrist have been used to estimate wrist muscle forces, but only at maximum voluntary contraction and only involving a single degree of freedom (DOF). In this study we present a method for creating a subject-specific model that can be used to estimate muscle forces and joint torques in both degrees of freedom of the wrist over a range of …

Practical Considerations Of Dissolved Oxygen Levels For Platelet Function Under Hypoxia, Branden Kusanto, Andrew Gordon, Leigh Naylor-Adamson, Lloyd Atkinson, Charlie Coupland, Zoe Booth, Yusra Ahmed, Isabel M Pires, Graeme J Stasiuk, Roger Sturmey, Simon D J Calaminus, Mònica Arman

Faculty, Staff and Student Publications

Investigating human platelet function in low-oxygen environments is important in multiple settings, including hypobaric hypoxia (e.g., high altitude), sea level hypoxia-related disease, and thrombus stability. These studies often involve drawing blood from which platelets are isolated and analysed at atmospheric conditions or re-exposed to low oxygen levels in hypoxia chambers before testing. However, it remains unknown how the in vitro handling of the samples itself changes their dissolved oxygen concentration, which might affect platelet function and experimental results. Here, we prepared healthy donor platelet-rich plasma and washed platelet (WP) suspensions and exposed them to 2% oxygen. We found that the …

Microfabricated Platforms To Investigate Cell Mechanical Properties, Amir M. Esfahani, Grayson Minnick, Jordan Rosenbohm, Haiwei Zhai, Xiaowei Jin, Bahareh Tajvidi Safa, Justin Brooks, Ruiguo Yang

Department of Mechanical and Materials Engineering: Faculty Publications

Mechanical stimulation has been imposed on living cells using several approaches. Most early investigations were conducted on groups of cells, utilizing techniques such as substrate deformation and flow-induced shear. To investigate the properties of cells individually, many conventional techniques were utilized, such as AFM, optical traps/optical tweezers, magnetic beads, and micropipette aspiration. In specific mechanical interrogations, microelectro- mechanical systems (MEMS) have been designed to probe single cells in different interrogation modes. To exert loads on the cells, these devices often comprise piezo-electric driven actuators that attach directly to the cell or move a structure on which cells are attached. Uniaxial …

Sometimes a symposium would wait until the hunt for a wild boar was over before starting. I hope that was not the motive behind your organizers hunting me down for this …

A Survey Of Stainless Steel In Medical And Surgical Application, Noah Slack, Clint Balch

ME 4133/6133 Mechanical Metallurgy

Stainless steels can be separated into four families based on the microstructure of the material: Austenitic, Ferritic, Martensitic, and Duplex. Each family provides a specific set of advantages and disadvantages, and material selection should be based on the specific application the material will be used for. For this study, the processing, microstructure, and performance of the four families of stainless steels will be compared in the context of medical device applications. The most important factors in medical device materials are biocompatibility, surface properties, mechanical properties and life span/corrosion resistance. This study will focus on medical devices that will be permanently …

The Process-Structure-Property-Performance Of Aisi 1020​, Jonathan Wellman, Tate James, Robbie Christman, Brian Broom

ME 4133/6133 Mechanical Metallurgy

AISI 1020 is widely used in many different industries due to its high strength, high ductility, high machinability, and good weldability. AISI 1020 has a number of applications. Low carbon steel can be used on a macroscale to build bridges, and low carbon steel can be used on smaller scales such as Lawnmower blades. Low carbon steel is the material of choice for lawn mower blades because of its ability to bend before it breaks. The ductile attribute of low carbon steel also has many other benefits.

Governor Leroy Collins Of Florida And The Selma Crisis Of 1965, Thomas R. Wagy

Florida Historical Quarterly

On Tuesday, March 9, 1965, a bright sun shone on Selma, Alabama, replacing the gray, gloomy weather which had blanketed the city for days. Despite the sixty degree temperature, the air held a winter crispness. Most of the people gathered at Brown’s Chapel wore heavy overcoats and gloves. The nervous conversations grew into an expectant murmur and then applause as a young black man came into view. He walked among the crowd, touched the extended hands, and moved to the church steps to speak. He was their leader. Arguments about whether or not to march ended. They would abide by …

Immigrants And Radicals In Tampa, Florida, George E. Pozzetta

Florida Historical Quarterly

The role that radical ideologies have played in the experience of America’s immigrant groups has been the subject of increasing scholarly attention. Historians are coming to realize that these philosophies often exerted a substantial influence on ethnic group development. This was particularly true of the manner in which immigrants interacted with the labor movement in America. That these developments have often been overlooked has been explained, in part, by a lack of documentary evidence available for use in charting the events, issues, and personalities of the radical world. In recent years, however, a growing volume of historical material has become …

William Edwards And The Historic University Of Florida Campus: A Photographic Essay, Stephen Kerber

Florida Historical Quarterly

The University of Florida officially dates its birth to the founding of the East Florida Seminary in 1853, but the university has really existed in its present form only since 1905. In that year the Florida legislature passed the Buckman Act (named for state Representative Henry H. Buckman, its main author), which consolidated the colleges, seminaries, and institutes receiving state support.

Helen Hunt West: Florida's Pioneer For Era, James R. Mcgovern

Florida Historical Quarterly

Since Florida's postion on the Equal Rights Amendment is considered critical in the interim remaining before the time limit for the amendment expires in 1979, it would seem particularly relevant to examine the historical roots of ERA in Florida. To do so is to unfurl the purple, gold, and white banner of the National Woman’s Party (NWP), the only organization which proposed ERA nationally in 1923 and which alone effectively propagandized on its behalf until the 1960s, and to focus on the activities of one of its key members, Helen Hunt West of Jacksonville.

Comparing Special Education Teachers’ Personality Profile With Their Choice To Teach, Laron A. Scott, Lauren Bruno, Philip Gnilka, Lindsay Kozachuk, Katherine Brendli, Vivian Vitullo

Excelsior: Leadership in Teaching and Learning

Researchers have yet to examine the association of Holland personality profiles as it relates to special education teachers. In response to this need, we report the personality and vocational profiles (Holland Codes) of 134 special education teachers across a special education training program. The purpose of this paper is to summarize findings from the Self-Directed Search measure commonly used to assess the personality of participants in an occupation and suggest implications for participants’ choice in becoming a special education teacher. Our focus was on personality match with vocational choice to include participants’ demographic (e.g., gender, race/ethnicity, and geographical location) profile. …

Enhancing Classroom Management Skills: Efficacy Of A Supplemental Multi-Platform Intervention For Preservice Teachers, Michael S. Rosenberg Phd, Sunny R. Duerr, Kate Ingraham, Karen Bell, Art Gould

Excelsior: Leadership in Teaching and Learning

Many teachers are ill-prepared to apply practices that can both preempt and address challenging behaviors that interfere with academic instruction. We evaluated the efficacy of a supplemental multi-platform (direct instruction, guided practice, and mixed reality simulations) intervention designed for preservice teachers who do not have opportunities to participate in formal classroom management courses. Efficacy of the intervention was assessed through the quality of classroom management plans, the presentation and implementation of the plan in the virtual classroom, and classroom management self-efficacy. Results indicated that preservice teachers successfully developed quality proactive classroom management plans but struggled to present and implement their …
