Shabbat 140 - July 24, 3 Av

Can one put eggs in a mustard strainer on Shabbat - why? If the mustard (oil or wine made from mustard) was kneaded in its own liquids before Shabbat, can one add liquid and mix it on Shabbat or is it a problem of kneading? Is there a difference if it is done with a utensil or by hand? Other drinks that people prepare in a way that involves kneading or may be used for medicinal purposes are discussed - can they be prepare don Shabbat or not? If one needs to take medicine for a number of days in a row, can one prepare the medicine on Shabbat? Can one rub a garment after laundering which was meant both to soften and to whiten - which is the main reason it is done? If for whitening, it would be forbidden. Rav Hisda has a long list of advice including financial, food-related, marital advice to his daughters, etc. Can one sweep the feeding trough of an animal on Shabbat? On what does it depend? Can one move food from one animal to another? It depends from which animal to which - how?
