Business plan22. Plan Review: Building Warehouse, Freezer Room and Fair in Tamarachin23. Background Design:• Highlights and important project: Nearing in Iraq boundary, Piransharcustom and having more trading transactions in this region, and need tomanage the exports from this region are the important factors to do thisproject.24. Resources needed:• Primitive materials: Sand, Cement, 3D-Panel, Asphalt, Brick,Prefabricated wall,…25. Regional and local construction projects:• It’s located in Piranshahr township in boundary common point between Iran and Iraq_in Tamar chin village_ that because of geographic, economic and security isimportant and for this reason is among the security small bazaars and Share offoreign exchange contract. Residents of this zones (between Iran and Iraq) becauseof no enjoyment from arable lands and no enough income from animal husbandry,and because of correlation and historical link between residents of two sides ofboundary, people get busy by good exchanges and smuggled of good was veryprevalent.26. Project engineering:• Equipments: equipments for building freezer room, warehouse and fair.27. Doing Time of project: About 3 months.28. Cost of project:• Costs:• Building freezer and cold rooms: about 5 billion Rials• Building fair salon: about 6 billion Rials

1975Ed White PhD at CSM modeled frequencydependent velocity in the presence of fluidmobility on a micro scale§§§Mathematically explored fluid mobility and dispersion.Importantly he posited the need for multi-phase fluid.His work explained difference between integrated sonictravel times and check shot travel times.16
