We measured mitomycin C (MMC) concentrations in ocular tissues in rabbits with variable dose (0.1, 0.2, or 0.4 mg) and duration of application time (1, 3, or 5 minutes) of MMC using high-performance liquid chromatography. Mitomycin C concentrations at the administered site after single subconjunctival application of MMC and after irrigation showed significant correlation with dose and duration ...

The Times graphics department has won many national and international awards, including the National Design Award for communication design. Learn how graphics editors report, design and edit data visualizations, integrate interactivity with story telling, and explain the news. How do basic ideas from journalism — including the importance of editing — influence the graphics the Times makes? Bio ...

Since 2013 researchers at University College Dublin in the Insight Centre for Data Analytics have been involved in a significant research programme in digital journalism, specifically targeting tools and social media guidelines to support the work of journalists. Most of this programme was undertaken in collaboration with The Irish Times. This collaboration involved identifying key problems cur...

swallow wort is a perennial weed which has caused damage in agricultural fields in iran especially in orchards. therefore, an experiment was conducted during 2009-2011 in order to its integrated management in arachis orchard in abyek based on randomized complete block design with three replications and 18 treatments. the treatments included gramaxon (paraquat 20% sl), roundup (glyphosate 41% sl...

We propose two Markov chains for sampling (m + 1)-dimensional contingency tables indexed by {1, 2}m × {1, 2, . . . , n}. Stationary distributions of our chains are the uniform distribution and a conditional multinomial distribution (which is equivalent to the hypergeometric distribution ifm=1). Mixing times of our chains are bounded by ( 1 2 )n(n− 1) ln(N/(2m ))= ( 1 2 )n(n− 1) ln(dn/ ), where ...
