Practical Guidance on Calculating Sampling Error in Election Polls
( American Association for Public Opinion Research , 2013 , Article)In election poll results, the proportions favoring candidates and the survey sampling error are usually reported. However, it is hard to assess if the gap between any two candidates is statistically significant or not based ... -
Practices of obtaining informed consent in Lebanon and Qatar: a disconnect between standards and practice
(2013 , Presentation)With the increasing number of universities in the Arab region, there has been a consequent increase in the number of research projects conducted particularly with human subjects. Despite the need to understand the application ... -
Pre treatment of melatonin rescues cotton seedlings from cadmium toxicity by regulating key physio-biochemical and molecular pathways
( Elsevier , 2023 , Article)Melatonin, a plant/animal origin hormone, regulates plant response to abiotic stresses by protecting them from oxidative damage. This study identified physiochemical and molecular mechanism of melatonin-induced cadmium ... -
Pre-fusion structure of a human coronavirus spike protein
( Nature Publishing Group , 2015 , Article)HKU1 is a human betacoronavirus that causes mild yet prevalent respiratory disease1, and is related to the zoonotic SARS2 and MERS3 betacoronaviruses, which have high fatality rates and pandemic potential. Cell tropism ... -
