( Public Library of Science , 2013 , Article)Background: In the present study, we investigated the effect of Origanum majorana ethanolic extract on the survival of the highly proliferative and invasive triple-negative p53 mutant breast cancer cell line MDA-MB-231. ... -
Mitotic Disturbances Induced By The Drug "Novalgin" In Allium Cepa Root Tips
( Qatar University , 1984 , Article)Growing root tips of Allium cepa are treated with seven concentrations of Novalgin ranging from 2.81 x 10 4 M to 1.5 x 10 4 M for 4, 8, 24,48 and 72 hours. The frequency of mitotic phases in the treated roots varies ... -
Mix and match: Collaborative expert-crowd judging for building test collections accurately and affordably
( CEUR-WS , 2018 , Conference Paper)Crowdsourcing offers an affordable and scalable means to collect relevance judgments for information retrieval test collections. However, crowd assessors may showhigher variance in judgment quality than trusted assessors. ... -
Mixed EWMA-CUSUM and mixed CUSUM-EWMA modified control charts for monitoring first order autoregressive processes
( Taylor and Francis Ltd. , 2017 , Article)In practice most processes are known to produce autocorrelated observations. Autocorrelation degrades the performance of control charts by producing frequent false alarms when the process is stable or makes the charts ... -
