Radiation Shielding Approaches For Planetary Surface Exploration: A Mars Case Study For Und Concepts, Arturo Ortiz

Theses and Dissertations

Surface stays on Mars may expose astronauts to high radiation doses from solar flares and galactic cosmic radiation (GCR). We estimated shielding required for a surface habitat, and assessed environments inside a planetary rover and space suit, under historically severe solar flare and GCR conditions, using the HZETRN radiation computer code. A 1m layer of Mars regolith can protect the habitat up to 30 km surface elevation. Polyethylene at 5, 10, and 15 g/cm2 can protect up to 0, 10, and 20 km, respectively. The rover protects from acute exposure up to -0.7 km while a space suit protects up …

The N-Terminus Of Type Iii Secretion Needle Protein Yscf From Yersinia Pestis Functions To Modulate Innate Immune Responses, Patrick Osei-Owusu

Theses and Dissertations

The type III secretion system is employed by many pathogens, including the genera Yersinia, Shigella, Pseudomonas, and Salmonella, to deliver effector proteins into eukaryotic cells. The injectisome needle is formed by the polymerization of a single protein, e.g., YscF (Yersinia pestis), PscF (Pseudomonas aeruginosa), PrgI (Salmonella enterica SPI-1), SsaG (Salmonella enterica SPI-2), or MxiH (Shigella flexneri). In this study, we demonstrated that the N termini of some needle proteins, particularly the N terminus of YscF from Yersinia pestis, influences host immune responses. The N termini of several needle proteins were truncated and tested for the ability to induce inflammatory responses …

Tamworth Conservatism And The Repeal Of The Corn Laws: The Foundation Of Modern Conservative Political Discourse, Jonathan James Hedeen

Theses and Dissertations

In the early morning hours of May 16th, 1846 Parliament gathered for the final reading to repeal the Corn Laws. While the Corn Laws had been a highly contested topic within Britain for over two decades, it was at this juncture that the Conservative party of Sir Robert Peel fractured. As this study shall demonstrate, the Corn Law crisis of 1846 did not destroy Peel’s version of Conservativism as has often been argued, but rather put it into a state of suspended animation. The division of the party only twelve years after its formation has long been a topic of …

Perceptions Of Computer-Generated Child Pornography, Beth Catherine Kliethermes

Theses and Dissertations

The current study examined public perceptions of computer-generated child pornography (CGCP) and its association with pornographic material acceptance, usage, and sexual interests, as well as attitudes regarding children and sexual activities. Moral Foundations Theory was utilized to interpret these findings from a morality perspective. Additionally, the study explored public perceptions regarding the use of computer-generated child pornography in treatment and its effect on risk of contact offending. Participants included a community sample recruited using Amazon’s Mechanical Turk. Results indicated that participants had significantly lower support for illegality of computer-generated child pornography when compared to child pornography; however, support for illegality …

The Expression Pattern Of Death Associated Protein Kinase1 In Normal Dorsal Root Ganglion Neurons And Following Peripheral Nerve Injury, Maryam Sulaiman Mohammed Al Saadi

Dissertations

Death-associated protein kinase1 (DAPK1) is a calcium/calmodulin (Ca2+/CaM) regulated serine/threonine kinase. An increasing body of evidence supports the significance of DAPK1 protein in cancer and CNS diseases. The role of DAPK in peripheral nerve regeneration and neuropathic pain remains completely unexplored. The aim of this study is to investigate the expression pattern of DAPK1 along with key proand anti-apoptotic cell signaling molecules (p53, Bax, Akt, ERK5, p38) and to verify the possibilities of DAPK1-NMDA NR2B relationship in dorsal root ganglion neurons (DRG) after 2 hours, 7 days and 14 days following a sciatic nerve injury. Gene expression analysis and immunohistochemistry …

A Preliminary Investigation Into The Relationship Between Functional Movement Screen Scores And Athletic Physical Performance In Female Team Sport Athletes, R.G. Lockie, A.B. Schultz, Samuel J. Callaghan, C.A. Jordan, T.M. Luczo, M.D. Jeffriess

Research outputs 2014 to 2021

There is little research investigating relationships between the Functional Movement Screen (FMS) and athletic performance in female athletes. This study analyzed the relationships between FMS (deep squat; hurdle step [HS]; in-line lunge [ILL]; shoulder mobility; active straight-leg raise [ASLR]; trunk stability push-up; rotary stability) scores, and performance tests (bilateral and unilateral sit-and-reach [flexibility]; 20-m sprint [linear speed]; 505 with turns from each leg; modified T-test with movement to left and right [change-of-direction speed]; bilateral and unilateral vertical and standing broad jumps; lateral jumps [leg power]). Nine healthy female recreational team sport athletes (age = 22.67 ± 5.12 years; height = …

Tunable Optical Nanocavity Of Iron-Garnet With A Buried Metal Layer, Alexey N. Kuz'michev, Lars E. Kreilkamp, Mohammed Nur-E-Alam, Evgeni Bezus, Mikhail Vasilev, Iliya A. Akimov, Kamal Alameh, Manfred Bayer, Vladimir I. Belotelov

Research outputs 2014 to 2021

We report on the fabrication and characterization of a novel magnetophotonic structure designed as iron garnet based magneto-optical nanoresonator cavity constrained by two noble metal mirrors. Since the iron garnet layer requires annealing at high temperatures, the fabrication process can be rather challenging. Special approaches for the protection of metal layers against oxidation and morphological changes along with a special plasma-assisted polishing of the iron garnet layer surface were used to achieve a 10-fold enhancement of the Faraday rotation angle (up to 10.8°=μm) within a special resonance peak of 12 nm (FWHM) linewidth at a wavelength of 772 nm, in …

Comparison Between Hear Rate Based Training, Perceived Effort, And Power Based Training In Competitive Elite Cyclists, Joshua Allen Carter

Theses

There are many different philosophies on how cyclist should train and about the different training modes available to them. It is important to know how to use these different modes of training to maximize the efforts. Training with power, heart rate, and perceived effort all have several advantages and disadvantages. The purpose of this study was to compare these different modes of training over an 8 week period to see if there is a difference between them. The participants were tested before and after the training period to show if there was any significant differences between them.

The study consisted …

Learning To Teach English Learners: Instructional Coaching And Developing Novice High School Teacher Capacity, Felice Atesoglu Russell

Faculty Articles

The number of English learners (ELs) in our schools continues to increase, and at the same time, the academic achievement of ELs consistently lags behind the achievement of native-English-speaking peers (Goldenberg & Coleman, 2010). These second language learners bring with them a set of special needs for teaching and learning, especially for mainstream content area teachers, who often have little or no specialized training for meeting these needs (Bunch, 2010). Although there is not yet extensive empirical work focused on how mainstream content teachers at the secondary level typically teach ELs or how they learn to more effectively teach these …

Zakrafah: Ornament In Islamic Style, Amani Alharbi

Theses

Ornament as an art has existed for many thousands of years. It is considered to be one of the most ancient forms of human visual expression. Ornament is a crucial part of such form of decoration as arabesque that has been widely used in Islamic architecture throughout the ages. However, ornament in Islamic art functions not only as a decoration. Patterns and colors used in ornament often convey symbolical meaning, which could be understood only by people of Islamic cultural background. Ornament has absorbed many unique and representative features of the outlook of Islamic people such as prevalence of the …

Lithostratigraphic Investigation And Components Of A Complete Petroleum System Within An Upper Devonian Carbonate-Evaporite Sequence : The Birdbear Formation, Williston Basin, North Dakota, Benjamin L. Engleman

Theses and Dissertations

The Birdbear Formation of the Williston Basin of southwestern North Dakota represents one carbonate-evaporite sequence of the Late Devonian. The formation was deposited during regression on a broad, shallow epeiric shelf and is composed principally of dolomite, limestone and anhydrite. The Birdbear Formation is conformable with the Duperow Formation below and the Three Forks Formation above. The designations of 17 lithofacies form the context for describing hydrocarbon generation, migration and accumulation. Rock-Eval 6 and total organic carbon of 42 samples were used to identify the quality of source rocks present in the formation. Good and excellent source rocks were identified …
