Introduction To The Special Issue On The Arab Spring, Ayodeji Kamau Perrin

Faculty Scholarship

What quickly became known as the "Arab Spring" is a series of protest movements, reform movements, and revolutions (some bloody and some relatively "bloodless") that has been ongoing for more than two years in the majority-Muslim world of the Middle East and North Africa. Arab Spring recalls both the European Revolutions of 1848, dubbed the "Springtime of the Peoples," as well as the Prague Spring of 1968. And the events have drawn comparisons to the post-Soviet revolutions of 1989. The compilation of essays contained in this Special Issue of the Journal of International Law reflects on these events from a …

Effect Of Microwave Heating On The Migration Of Additives From Ps, Pp And Pet Container Into Food Simulants, Ruoyin Cai

Theses

Microwave food packaging has become a tremendous element in the food manufacturing process. The purpose of any food packaging regulations concerned with the safety of the food is to control and limit the migration of substances from the packaging into the food. The main objective of this thesis is to test three different microwaving packaging materials that are the most common material in the market, viz. polystyrene (PS), polypropylene (PP), and polyethylene terephthalate (PET), migrated into four food simulant solutions. Four different simulant solutions were used based on the food type and FDA recommendations and regulations. These food simulants include …

Perceived Experiences Of Discrimination In Health Care: A Barrier For Cancer Screening Among American Indian Women With Type 2 Diabetes, Kelly Gonzales, Anna K. Harding, William E. Lambert, Rongwei Fu, William G. Henderson

OHSU-PSU School of Public Health Faculty Publications and Presentations

Purpose - Breast and cervical cancer-mortality disparities are prominent among American Indian women. These disparities, in part, may result from patients perceived experiences of discrimination in health care. This report evaluates the impact of perceived discrimination on screening for breast and cervical cancer in a sample of 200 American Indian women with type 2 diabetes.

Methods - Data were collected from patient report and medical records. Prevalence of breast and cervical cancer screening were assessed. Unadjusted and adjusted logistic regression analyses were used to assess associations between perceived discrimination, cancer screening status, and patients' health care-seeking behaviors.

Findings - Substantial …

Dinitrogen Fixation In Aphotic Oxygenated Marine Environments, Eyal Rahav, Edo Bar-Zeev, Sarah Ohayon, Hila Elifantz, Natalia Belkin, Barak Herut, Margaret R. Mulholland, Iiana Berman-Frank

We measured N₂ fixation rates from oceanic zones that have traditionally been ignored as sources of biological N₂fixation; the aphotic, fully oxygenated, nitrate (NO¯₃)-rich, waters of the oligotrophic Levantine Basin (LB) and the Gulf of Aqaba (GA). N₂ fixation rates measured from pelagic aphotic waters to depths up to 720 m, during the mixed and stratified periods, ranged from 0.01 nmol N L^-1 d^-1 to 0.38 nmol N L^-1 d^-1. N₂ fixation rates correlated significantly with bacterial productivity and heterotrophic diazotrophs were identified from aphotic as well as …

Combined Effects Of Co2 And Light On Large And Small Isolates Of The Unicellular N2-Fixing Cyanobacterium Crocosphaera Watsonii From The Western Tropical Atlantic Ocean, Nathan S. Garcia, Fei-Xue Fu, Cynthia L. Breene, Elizabeth K. Yu, Peter W. Bernhardt, Margaret R. Mulholland, David A. Hutchins

OES Faculty Publications

We examined the combined effects of light and pCO₂ on growth, CO₂-fixation and N₂-fixation rates by strains of the unicellular marine N₂-fixing cyanobacterium Crocosphaera watsonii with small (WH0401) and large (WH0402) cells that were isolated from the western tropical Atlantic Ocean. In low-pCO₂-acclimated cultures (190ppm) of WH0401, growth, CO₂-fixation and N₂-fixation rates were significantly lower than those in cultures acclimated to higher (present-day approximate to 385ppm, or future approximate to 750ppm) pCO² treatments. Growth rates were not significantly different, however, in low-pCO₂-acclimated cultures of …
