(shown in figure (1) below) the fluid is accelerated through a converging cone of angle 15-20° and the pressure difference between the upstream side of the cone and the throat is measured and provides the signal for the rate of flow. Upstream pressure tap Downstream pressure tap Venturi Throat Upstream Flow Figure (1) : The Venturi meter operation. Downstream Flow The fluid slows down in a cone with smaller angle (5-7°) where most of the kinetic energy is converted back to pressure energy

mainly delivered to residential customers. This chapter focus mainly on defining ADSL. Asymmetric Digital Subscriber Line Asymmetric Digital Subscriber Line (ADSL) technology is asymmetric. It allows more bandwidth downstream—from an NSP’s central office to the customer site—than upstream from the subscriber to the central office. This asymmetry‚ combined with always-on access (which eliminates call setup)‚ makes ADSL ideal for Internet/intranet surfing‚ video-on-demand‚ and remote LAN access. Users

more entities directly involved in the upstream and downstream flows or products‚ services‚ finances‚ and information form a source to a customer. From this definition we can identify three degrees of supply chain complexity: a direct supply chain‚ and extended supply chain‚ and an ultimate supply chain. A direct supply chain consists of a company‚ a supplier‚ and customers of the immediate customer‚ all of witch are involved in the upstream and downstream flows of products‚ services‚ finances

COSTS It is the consensus of Team 10 that the bullwhip effect increases costs associated with the manufacturing of products. We know that the bullwhip effect results in an amplification of the variation of product and material demand as one travels upstream in the supply chain from consumer to material suppliers. In most cases the manufacturer of products will be removed from the actual consumer by multiple layers in the supply chain. The variation in demand (variation in orders) that the manufacturer

ABSTRACT Acid Mine Drainage (AMD) problems are the most important environmental problems in sulphide mines especially mines which contain pyrite. Oxidation of sulphides in contact with air and water produces sulphuric acid which reduces the pH of water. The result of these reactions is increase in the solubility of heavy metals and consequently pollution of water resources. The Sarcheshmeh copper mine is one of the largest porphyry copper mines in the world which is located in south-eastern Iran

Sometimes there might less than 4 supply chain partners in a game. The two types of flows in this supply chain include product and information. There may be delay in these flows‚ which could be 1 or 2 weeks or in some cases no delay. Shipment (product flow) is made downstream and information is transmitted

According to Gabriel V. Jasul‚ Interventions for a multifactorial condition such as obesity can be categorized according to so-called ecological levels‚ i.e.‚ downstream‚ upstream and midstream. Briefly‚ downstream factors involve individual decision-making that influences personal preferences and habits. Upstream factors‚ on the other hand‚ are at the community and national levels that may include infrastructure and community planning that may influence lifestyle (diet‚ physical activity) in the
