EXPERIMENT 1 COLLIGATIVE PROPERTIES OF SOLUTIONS Date: December 03‚ 2013 Locker 21 Members: Vanessa Olga Dagondon Christine Anne Jomocan Janica Mae Laviste Nablo Ken Menez A. TYPES OF DISPERSED SYSTEMS Results and Discussion The first part of the experiment aims to differentiate the different dispersion systems. In this experment‚ three systems are introduced: true solution‚ colloidal dispersion and coarse mixture. The said three systems are classified through a property of colloids known as the

TOYOTA MOTOR MANUFACTURING‚ U.S.A.‚ INC. The Problem: Because issues with seats are mainly caused by the defective seats being sent by KFS‚ Friesen should focus his initial investigation on the process used when the seat assemblies are initially manufactured. Defective and/or incorrect seats being installed in the vehicles will only cause re-work and backlog in the Overflow Parking Area‚ so if there is a way to decrease the amount of re-work to be done‚ Friesen should try to identify it.

KSF. Most of the seat problems were occurring because of this mismanagement like‚ wrong‚ missing and broken parts‚ wrinkles and missing bolster. Also‚ KSF inspection of seats before shipping is not proper. There need to check the method followed by KFS while inspection of seats because several of defective seats are being send as fit. May be by providing more training to the worker this problem could be solved. Also‚ there was ineffective feedback system‚ due to which Doug was not able to reach the

1972‚ Sweden’s National Board of Health and Welfare developed the idea of "basic foods" that were both cheap and nutritious‚ and "supplemental foods" that added nutrition missing from the basic foods. Anna Britt Agnsäter‚ head of the test kitchen at KF‚ a consumer co-op that worked with the Board‚ held a lecture the next year on how to illustrate these food groups. Attendee Fjalar Clemes suggested a triangle displaying basic foods at the base. Agnsäter developed the idea into the first food pyramid
