For those synagogues reading Torah according to the triennial cycle, what should be their practice with regard to the custom of saying “hazak, hazak, v’nithazek”? Should they say that phrase only at the end of each book – and thus only when they are reading the last third of each of the annual Torah readings – or may they say it also when reading the first and second portions of the annual Torah readings? If the latter, how should they do that?

In the event of the tragedy of a stillbirth or the death of an infant boy, must there be a brit milah, circumcision, before burial? Many male Jews from the former Soviet Union did not have a brit milah as children and, even after emigrating, did not arrange for their circumcision. When they die, must they be circumcised before burial? In either case, if circumcision is required, would this be considered part of the regular preparation for burial or, would the surviving family have to be informed and provide explicit consent?

Why do Ashkanazic Jews refrain from eating rice, beans and kitniyot on Pesah? Is there any way of doing away with this custom which causes much hardship and also divides Jewish communities and even members of the same family?
