Effects Of Low Concentrations Of Carbon Nanotubes On Growth And Gas Exchange In Arabidopsis Thaliana, Rajeeva Voleti

Graduate Theses/Dissertations

The effect of pure single-walled carbon nanotubes (SWCNTs) on plant growth and gas exchange was investigated in Arabidopsis thaliana. To date there has been no research on the effects of SWCNTs on whole plant physiology. A. thaliana seeds were directly grown in growth medium containing SWCNTs concentrations of 24.93micrograms/ml and 53.55 micrograms/ml. control plants were grown in media containing distilled water. I determined growth by measuring dry mass of plants. I determined gas exchange by measuring photosynthetic rates, stomatal conductance, transpiration rates, and water use efficiency. I also examined the following physiological mechanisms that would limit plant growth: ATP and …

Dynamin Association With Clathrin And Its Physiological Roles At The Golgi And Targeting Mechanism To The Golgi, Shiva Kumar Goud Gadila

Graduate Theses/Dissertations

Vps1 (Vacuole protein sorting 1), a dynamin-like protein in yeast, is implicated in diverse membrane trafficking pathways and localized to many organelles, including the Golgi. It has been proposed that Vps1 is functionally linked to clathrin heavy chain 1 (Chc1), but the question of how, where, and when they function together remains unknown. Lines of evidence suggest that Chc1 and Vps1 are located at the late Golgi. Therefore, I hypothesized that Vps1 binds to Chc1 and functions together at the Golgi for efficient Golgi-to-endosome membrane trafficking. Using the yeast-two hybrid assay, I present evidence that Vps1 binds to the C-terminal …

Is Using The Public Trust Doctrine To Protect Public Parkland From Visual Pollution Justifiable Doctrinal Creep?, Hope M. Babcock

Georgetown Law Faculty Publications and Other Works

This Article asks whether the public trust doctrine should be applied to stop the construction of a multistory commercial building that will tower over the tree line of Palisades Interstate Park. The building, which received a variance from a local New Jersey zoning commission, will ruin views of the Park, particularly from scenic overlooks across the Hudson River in New York, like the Metropolitan Museum’s Cloisters and the George Washington Bridge. To make this argument, the author draws on the work of renowned public trust scholars, Professors Joseph Sax and Carol Rose, among others. Based on the doctrine’s adaptability to …

Copy And Paste: Transplanting International Hiv/Aids Model Laws Into African Countries, Maya Berinzon

Cardozo Journal of International and Comparative Law

There has been a recent increase in legislative and regulatory frameworks to govern HIV in Africa. This includes rules on when and how a health practitioner may disclose the HIV status of a patient to a spouse or sexual partner. In balancing the right to privacy against a doctor's duty of care, two international model laws have emerged, and have been wholly or partially copied by a number of African countries. This paper questions the usefulness of such model laws as legal transplants in national legislatures through an analysis of the regulations developed in thirty-eight African countries.

Public Health Sciences Articles

Height has an extremely polygenic pattern of inheritance. Genome-wide association studies (GWAS) have revealed hundreds of common variants that are associated with human height at genome-wide levels of significance. However, only a small fraction of phenotypic variation can be explained by the aggregate of these common variants. In a large study of African-American men and women (n = 14,419), we genotyped and analyzed 966,578 autosomal SNPs across the entire genome using a linear mixed model variance components approach implemented in the program GCTA (Yang et al Nat Genet 2010), and estimated an additive heritability of 44.7% (se: 3.7%) for this …

Menon, Kedar V. Inamdar

Pathology and Laboratory Medicine Articles

Blast phase in chronic myelogenous leukemia (CML) has rarely been reported to involve extramedullary sites like skin, lymph nodes, and central nervous system. Clinical history, characteristic hematologic findings (elevated leukocyte counts, myelocytic predominance, and basophilia), and Philadelphia chromosome are of high diagnostic significance especially in isolated extramedullary presentations. We describe a unique case of CML relapse with blast phase involving the eye. A 66-year-old man with a known diagnosis of CML on imatinib and in molecular remission for 3 years presented with a painful blind eye. Histologic examination revealed diffuse involvement of choroid, iris, vitreous humor, and the optic nerve …

Supportive Housing Outcomes For Ex-Offenders: Correlations Between Criminal History And Tenancy Success, Emma F. Grochowsky

Master of Arts in Criminal Justice Theses

Ex-offenders face a variety of social, economic, and legal barriers to housing due to their criminal convictions. While many of these barriers exist due to the belief that convicted exoffenders are dangerous tenants, few empirical studies have actually evaluated this relationship. This study examines the relationship between criminal history and housing success for formerly homeless and low-income individuals in a supportive housing environment, both with and without criminal histories. Housing outcomes are measured through length of tenancy, lease violations during tenancy, and reasons for leaving. Implications for future research and housing policies are discussed.

Student Perceptions Of Biology Teachers' Interpersonal Teaching Behaviors And Student Achievement, Victor N. Madike

Walden Dissertations and Doctoral Studies

Inadequate student-teacher interactions in undergraduate courses have been linked to poor student performance. Researchers have noted that students' perceptions of student-teacher relationships may be an important factor related to student performance. The administration of a Mid-Atlantic community college prioritized increasing undergraduate biology student performance. The purpose of this quantitative study was to examine the relationship between students' biology achievement and their perceptions of interpersonal teaching behaviors and student-teacher interactions in introductory biology courses. Leary's theory on interpersonal communication and the systems communication theory of Watzlawick, Beavin, and Jackson served as the theoretical foundation. The Wubbel's Likert-scale questionnaire on student-teacher interactions …

Faculty Willingness To Complete Information Technology Training On Course Management Systems, Audrey S. Pereira

Walden Dissertations and Doctoral Studies

The literature suggests that information technology (IT), including Course Management Systems (CMSs), allows higher education faculty members (HEFMs) to adopt better methods for teaching and learning, and that training contributes to adoption. However, many HEFMs are unwilling to complete IT training on the CMS, contributing to low adoption rates. Yet, little is known about what influences HEFMs to complete IT training on their institution's CMS, even though CMSs are widely available. The purpose of this study was to address this gap in the literature through a quantitative, cross-sectional study of HEFM perceptions of CMS characteristics, based on Rogers' diffusion of …

The Association Between Exhaled Nitric Oxide In Exhaled Breath Condensate And Chronic Obstructive Pulmonary Disease, Colin Mitchell

Walden Dissertations and Doctoral Studies

Chronic obstructive pulmonary disease (COPD), a progressive and nonreversible disease, is a leading cause of mortality and morbidity throughout the world. Detecting COPD early in the disease process will help in decreasing later stage COPD severity. Because airway inflammation is a hallmark of COPD, it has been proposed that measuring exhaled nitric oxide, a marker of inflammation, in exhaled breath condensate could prove to be an inexpensive and efficient method to detect COPD in outpatient settings. Using the hypothetico-deductive theory as a guideline, this study used secondary data from the National Health and Nutrition Examination Survey 2007 to 2010 to …

Relationship Between Modality And The Degree Of Knowledge Retention In Bioterrorism Training, Gaylon Rashun Crawford

Walden Dissertations and Doctoral Studies

A public health workforce must be trained to react quickly, especially in the case of terrorist attack. Political leaders and emergency management experts have often cited inadequate emergency training as a contributing factor in the public health system's failed preparations for a bioterrorist event. As a result of these failures, billions of dollars have been allocated towards correcting infrastructure deficiencies including training for public health nurses (PHNs), who are critical to a communitywide medical response. This quantitative study used Pearson's correlation and a multivariate regression analysis to evaluate the most effective modality of bioterrorism training (BTT) for PHNs working in …

Indentifying Effective Communication Practices For Eliciting Parental Involvement At Two K-8 Schools, Karen Lynn Moore

A Comparison Study Of Gender Role Differences Between Funeral Professionals And Nurses, David Rocco Penepent

Walden Dissertations and Doctoral Studies

Women comprise over 57% of all U.S. mortuary school students, yet less than 20% of all funeral directors employed in this country are women. As such, women are underrepresented as funeral directors in the funeral industry. Research to date has not established clear differences between perceived gender roles and occupations in the funeral service industry. The research questions examined the perceived differences of gender role characteristics of masculine, feminine, and androgyny between the occupations of funeral service providers and nursing. Bem's gender role theory was the theoretical framework of this study. The research compared the mean scores of male and …
