Enhanced Label Free Normal And Cancer Cells Classification Using Combined Parametric Modeling And Optical Techniques, Ayshathul Fouzia Abdul Gani

Dissertations

The development of label-free methods for cell classifications has been driven by the importance of early detection and identification of cancer disease. The future point-of-care (POC) treatment methods require rapid and real-time cancer screening techniques. As the labelled methods of cell classification are time-consuming processes and require a large amount of sample preparation along with skilled persons, they do not appear to be suitable for POC treatment methods. This necessitates the importance of such development. The label-free methods incorporate the biophysical properties of cells instead of biomarkers. The optical properties of cells have been frequently utilized for cell classification. This …

Understanding Violent-Crime Recidivism, J. J. Prescott, Benjamin David Pyle, Sonja B. Starr

Faculty Scholarship

People convicted of violent crimes constitute a majority of the imprisoned population but are generally ignored by existing policies aimed at reducing mass incarceration. Serious efforts to shrink the large footprint of the prison system will need to recognize this fact. This point is especially pressing at the time of this writing, as states and the federal system consider large-scale prison releases motivated by the COVID-19 pandemic. Those convicted of violent crimes constitute a large majority of older prisoners, who are extremely vulnerable to the spread of the virus behind bars. Excluding them from protective measures will deeply undermine those …


Me Too? Incentivising States To Adopt Consent-Based Sex Education, Seth Reiner Jan 2020

Me Too? Incentivising States To Adopt Consent-Based Sex Education, Seth Reiner

Faculty Scholarship

In November 2018, Columbia University published a study showing that students who received formal sex education before entering college that included training in refusing unwanted sex were half as likely to be assaulted as those who had not. That study claims to be the first to research sex education’s effect on sexual violence instead of its impact on pregnancy or HIV prevention. A different study, conducted by Planned Parenthood in 2015, shows confusion around the definition of sexual consent itself: it found that 19% of people strongly agreed that not saying “no” indicated consent for more sexual activity, whereas 20% …

Land Of The Falling "Poison Pill" Understanding Defensive Measures In Japan On Their Own Terms, Alan K. Koh, Masafumi Nakahigashi, Dan W. Puchniak

Research Collection Yong Pung How School Of Law

Embraced by United States ("U.S.") managers in the 1980s as a lifeline in a sea of hostile takeovers, the poison pill fundamentally altered the trajectory of American corporate governance. When a hostile takeover wave seemed imminent in Japan in the mid-2000s, Japanese boards appeared to embrace this American invention with equal enthusiasm. Japan's experience should have been a ringing endorsement for the utility of American corporate governance solutions in foreign jurisdictions -but it was not to be. Japan's unique interpretation of the "poison pill" that was so eagerly adopted by Japanese companies in the mid-to-late 2000s has turned out to …

Stable Dispersion Of Coal Fines During Hydraulic Fracturing Flowback In Coal Seam Gas Reservoirs - An Experimental Study, Faisal Ur Rahman Awan, Alireza Keshavarz, Hamed Akhondzadeh, Sarmad Al-Anssari, Ahmed Al-Yaseri, Ataollah Nosrati, Muhammad Ali, Sefan Iglauer

Research outputs 2014 to 2021

In subterranean coal seam gas (CSG) reservoirs, massive amounts of small-sized coal fines are released during the production and development stages, especially during hydraulic fracturing stimulation. These coal fines inevitably cause mechanical pump failure and permeability damage due to aggregation and subsequent pore-throat blockage. This aggregation behavior is thus of key importance in CSG production and needs to be minimized. Consequently, such coal fines dispersions need to be stabilized, which can be achieved by the formulation of improved fracturing fluids. Here, we thus systematically investigated the effectiveness of two additives (ethanol, 0.5 wt % and SDBS, 0.001 and 0.01 wt …
