Large-scale basin testing to simulate realistic oil droplet distributions from subsea release of oil and the effect of subsea dispersant injection

Small-scale experiments performed at SINTEF, Norway in 2011–12 led to the development of a modified Weber scaling algorithm. The algorithm predicts initial oil droplet sizes (d50) from a subsea oil and gas blowout. It was quickly implemented in a high number of operational oil spill models used to predict fate and effect of subsea oil releases both in academia and in the oil industry. This paper presents experimental data from large-scale experiments generating oil droplet data in a more realistic multi-millimeter size range for a subsea blow-out. This new data shows a very high correlation with predictions from the modified Weber scaling algorithm both for untreated oil and oil treated by dispersant injection. This finding is opposed to earlier studies predicting significantly smaller droplets, using a similar approach for estimating droplet sizes, but with calibration coefficients that we mean are not representative of the turbulence present in such releases.publishedVersio

"Young Women Growing Graciously": Considering Sport, Gender and Development in Diasporic Space

This thesis aims to expand our understanding of the relationship between gender, sport and development. Specifically, it asks 1) how a sport, gender and development program is conceptualized and deployed by members of a young Somali-Canadian women’s group in Toronto, Canada and 2) if female participation in sport is thought to contribute to new gender norms, roles and relationships within such a diaspora community. Working within a postcolonial/transnational feminist framework, the thesis utilizes focus group interviews and engages with issues of power, representation and knowledge production. The findings shed light on the influences that have both informed and constrained this particular community initiative, as well as the possibilities and limitations of using sport to negotiate new gender norms, roles and relationships within the Somali diaspora. In conclusion, several recommendations are made to researchers and practitioners invested in the burgeoning field of international sport for development.MAS

Biomarker discovery and authentication of cold-slaughtered chicken through classical analytical procedures and mass spectrometry based proteomic approaches

1. This study evaluated the suitability of routine analytical procedures and used mass spectrometry based proteomic approaches to distinguish meat from dead chicken/ cold slaughtered birds (CS), electrically stunned and slaughtered birds, as per standard protocols (ES), and birds slaughtered according to halal guidelines (HS). 2. Meat from CS birds had lower (P P  3. The results demonstrated the presence of unique protein bands on SDS-PAGE only in CS meat that can be used for routine screening. 4. Protein analysis using MALDI-TOF mass spectrometry has identified haemoglobin subunit alpha-A and alpha-D; Adenylate kinase isoenzyme 1 as reliable and stable marker proteins for authentication of dead chicken meat under raw and cooked conditions and halal slaughtered chicken, respectively. 5. The methods used may be employed by the food safety and regulatory agencies for regular screening of meat quality and to authenticate CS or HS chicken.</p
