the objective of this study was to estimate genetic parameters coupled with genetic and phonotypic trends for age at first calving (afc), open days(od) and milk yield(my) of first lactation in iranian holstein cows. records of reproduction and production for genetic evaluation from 1984 to 2005 for afc, od and my were 71736, 20126 and 20126, respectively. single and two-variable animal models w...

In this text, associated with my opening lecture at the first INDRUM Conference, I will reflect on the achievements and challenges of mathematics education research at university level, in the light of my experience both as a researcher and a university teacher. First, I will come back to the historical evolution of this field of research through the retrospective analysis of some selected epis...

fasting and diabetes has been on my radar from a local perspective for years. as a dietitian many of my patients chose to fast with the goal to promote better health. most recently, my perspective on fasting became global as working with the managing diabetes during ramadan initiatives.in april 2016, international diabetes federation (idf) and the diabetes and ramadan (dar) international allian...
