In addition to the equations of linear impulse and momentum considered in the previous lecture, there is a parallel set of equations that relate the angular impulse and momentum. Angular Momentum We consider a particle of mass, m, with velocity v, moving under the influence of a force F. The angular momentum about point O is defined as the \moment\ of the particle's linear

Chapter 3 Pressure-activated membrane processes M. J. LEWIS, Department of Food Science and Technology, The University of Reading, Reading RG6 6AP 3.1 INTRODUCTION Over the last 30 years, a number of membrane processes have evolved, which make use of a pressure driving force and a semi-permeable membrane in order to effect a separa- tion of components in a solution or colloidal dispersion. The separation is based mainly on molecular size, but to a lesser extent on shape and charge. The three main processes

If the global economy falters, free trade will suffer \I'M MAD as hell, roared the man on stage. \Mad as hell about what is happening to the manufacturing sector in America. \ This is a trade war with China,\ shouted his colleague, \and it's time to fight that war head on.\ The audience cheered in approval. Patriotic songs played in the background, interspersed with extracts from George Bush's address to the nation after September

Introduction The consumption-based model as a complete answer to most asset pricing question in principle, does not work well in practice; This observation motivates effects to tie the discount factor m to other data; Linear factor pricing models are most popular models of this sort in finance; They dominate discrete-time empirical work
