Theory of Ion-Atom Collisions for Stopping Power Calculations

This thesis is devoted to calculations of stopping power in ion-atom and ion-molecule collisions. A single-centre convergent close-coupling method is used to calculate the stopping power of simple atoms and molecules, including the water molecule, for antiprotons. A two-centre convergent close-coupling method, which includes electron capture, is used to calculate the stopping power of hydrogen for protons. The results presented in this thesis can be used for radiation-dose simulations in hadron therapy

The Continuous Journey

The following work has compiled over the course of my time spent at Claremont Graduate University. Through my time in the program I have not only developed as an educator but an individual as well. My journey began simply by looking at myself and who I am. I thought I knew who I was, but as I continued with my courses, spent more time in the classroom, and engaged in professional relationships I began to wonder. Throughout this ethnography, I will share my experiences and journey through this roller coaster year. However, as I reflect now, I can begin to appreciate the journey I have been on and look forward to what lies ahead. I began my journey fresh out of my undergrad program ready to begin my teaching career. Coming into this program I felt ready to take on anything they threw at me because, obviously, I was prepared. My work through this ethnography has shown me that although my past experiences did provide a great foundation, there was much more to learn and experience. As I spent the second portion of this writing getting to know my focus students, I realized that I had spent so much time in my own world that I needed to step back and observe and appreciate all that was around me. This idea lent itself to the third section of my ethnography. Here I was at a school seven minutes from my home and I had never seen it. There was this whole world down the street that I had never experienced, but my students lived every single day. My work this past year has been a reflection of my growth as a teacher, a person, and a student. The adage “You learn something new everyday” has never been more prevalent than on my journey through the Claremont Graduate University, Teacher Education program. However trying and overwhelming it all was, I still had my family, my friends, and my students to keep my head above water and keep me going. I dedicate this ethnography to them all because without their love and support through this tumultuous journey, I would not be walking away the educator I am today

Making the invisible visible : black women, Broadway, and post-blackness

textPrior to the fall of 2011, only eight African American female playwrights had ever been produced on Broadway. In this context, the 2011-2012 Broadway season made theatre history when it featured the work of three black women playwrights: Stick Fly by Lydia Diamond, The Mountaintop by Katori Hall and an adaptation of The Gershwin’s Porgy and Bess by Suzan-Lori Parks. This project, which focuses on Diamond’s Stick Fly and Hall’s The Mountaintop as Broadway debuts of new plays, seeks to situate these works within a post-black aesthetic that rejects narrow and limiting constructions of blackness. This project also recognizes the significance of Diamond and Hall as female African American playwrights whose texts allow for complex representations of black womanhood, and proposes that the relationship between post-blackness and black feminism is fluid and permeable, allowing us to better understand both the meanings of blackness and the experiences of black women.Theatre and DanceTheatre and Danc

Developing methods for antibody-mediated enrichment and capture of spermatozoa from complex cell mixtures for forensics applications

Cases of sexual assault have steadily increased over the past years. Sexual assault samples are complex with vaginal epithelial cells as the main contributor to the sample, while spermatozoa are vast in number. There a variety of techniques such as differential extraction and laser capture microdissection that exist to isolate and capture spermatozoa for DNA profiling. These methods are tedious and are not always efficient. Anti-sperm antibodies can be used to target spermatozoa by binding to antigens localised on the surface of the acrosome. This study tested the binding capacity of a variety of anti-sperm antibodies to fresh and aged spermatozoa. The binding ability of the α-SPAM1 primary antibody to spermatozoa eluted from Copan rayon swabs was assessed to evaluate that the number of spermatozoa stained was sufficient for STR analysis. This study showed that α-SPAM1 and α-SPACA1 stained more than >30% of cells in fresh and aged spermatozoa. This study found that 39% of aged spermatozoa were stained with a combination of α-SPAM1 and α-SPACA1. It was found that Copan rayon swabs were efficient at absorbing spermatozoa but only released <50% of cells. Copan rayon swabs retain 33% of initial spermatozoa consumed. The study found that despite the high retention capacity of Copan rayon swabs, sufficient numbers of spermatozoa were eluted and stained with α-SPAM1 at levels compatible with DNA techniques such as STR analysis. In conclusion, this study shows that in future studies, α-SPAM1 and α-SPACA1 could be used to in conjunction with immunomagnetic beads to extract spermatozoa from sexual assault samples

Editor\u27s Note

Dear Readers, For more than two decades, the Sustainable Development Law and Policy Brief (SDLP) remains true to its mission of providing innovative solutions to some of the most important legal issues related to environmental law, energy law, and natural resources law. We are honored to be the Editors-in-Chief during these unprecedented times in our history, as we witnessed a historical presidential election and now enter the third year of the COVID-19 global pandemic. Despite these unparalleled times, the SDLP staff brought our readership another great issue. In this issue, our authors provide an in-depth analysis into current regulations and the potential direction and solutions these regulations may take in the future. From ocean pollution, to the National Environmental Protection Act (NEPA), to tiny homes, and wildlife management, the challenges addressed in this issue have a rather narrow focus, but potentially broad impacts on our environment, both domestically and globally. The Keylon article outlines the impacts of NEPA in the time of the Trump Administration and how the Biden Administration has taken steps to restore NEPA regulations to pre-Trump standards. Keylon also takes it one step further and poses ways in which the Biden Administration can strengthen NEPA standards that would go beyond the pre-Trump standards. The Chu article describes society’s addiction to plastic and the damage it reaps on the health of our planet and the health of humans. Chu discusses these problems by calling on local, state, and federal governments to address the issues of plastics and waste, while simultaneously encouraging individuals to use their voice to enact change. Both articles provide hopeful and possible solutions by building on already-existing frameworks. We would like to thank all the article and feature authors for their insights and dedication to raising important legal issues. Also, we would like to thank the professors, executive board, staff, and publisher of SDLP for making this publication possible. SDLP is a team endeavor, and a team has never been more important than in the times of COVID-19, so everyone’s work is appreciated. Finally, we would like to thank our readers, whose involvement and investment in SDLP are the reasons that we have been able to create this publication for more than twenty years

Editor\u27s Note

The Sustainable Development Law and Policy Brief (“SDLP”) is celebrating twenty-two years of legal scholarship on issues related to environmental, energy, natural resources, and international development law. SDLP continues to provide cutting-edge solutions to these legal issues in the face of the global COVID-19 Pandemic, while also transitioning back into a “new normal.” This issue is no different, as we published articles challenging our lawmakers and policy heads to address the impending needs of our communities to develop more sustainable infrastructure—needs that are only exacerbated by man-made climate change. We are proud of the work published, and we are forever thankful to our staff who worked tirelessly on these pieces to bring our readership another great issue

Summations and transformations for multiple basic and elliptic hypergeometric series by determinant evaluations

Using multiple q-integrals and a determinant evaluation, we establish a multivariable extension of Bailey's nonterminating 10-phi-9 transformation. From this result, we deduce new multivariable terminating 10-phi-9 transformations, 8-phi-7 summations and other identities. We also use similar methods to derive new multivariable 1-psi-1 summations. Some of our results are extended to the case of elliptic hypergeometric series.Comment: 29 pages, minor changes; to appear in Indag. Math., special volume dedicated to Tom Koornwinde

Determining The Cost Effectiveness Of Solutions To Diffuse Pollution: Developing A Model To Assess In-Field Mitigation Options for Phosphorous and Sediment Loss

The European Union Water Framework Directive requires governments to set water quality objectives based on good ecological status. This includes specific requirements to control diffuse pollution. Diffuse phosphorous (P) pollution plays a pivotal role in influencing water quality with losses of P associated with soil particles often linked to soil erosion. The Mitigation Options for Phosphorus and Sediment (MOPS) project, using three case study sites, is investigating the cost effectiveness of specific control measures in terms of mitigating sediment and P loss from combinable crops. The analysis is conducted at the farm level using a simple spreadsheet model. Further development of the model will allow the results to be extrapolated to generic regional farm typologies. Results from the initial farm level analysis suggest that some mitigation options may not be cost effective in reducing diffuse pollution, however, that other options may be very cost effective.Resource /Energy Economics and Policy,

Different representations of continuum in the positron-hydrogen scattering problem

A two-centre convergent close coupling method is applied to positron-impact ionisation of hydrogen. Different ways of distributing the pseudostates representing the continuum are investigated. It is found that calculations of the grand total and total ionisation cross sections are independent of the distribution of continuum pseudostates
