ROM and the first commercial (MOSFET) Silicon gate SRAM chip. Intel ’s business grew during the 1970s as it expanded and improved its manufacturing processes and diversified its products‚ still dominated by various memory devices. While Intel created the first commercially available microprocessor (Intel 4004) in 1971 and one of the first microcomputer in 1972‚ by the early 1980s its business was dominated by dynamic random-access memory chips. However‚ increased competition from Japanese semiconductor

Seamus Heaney – ‘At a Potato Digging’ • Context • • The poem deals with two different potato harvests. One is the harvest from the present day that goes successfully and which delivers a rich crop. The second potato harvest looks back to the famine of 1845 when the crop failed and many people starved. Whilst the famine is no longer a threat‚ its ongoing fear remains and this can be seen in the use of religious language throughout the poem. For example‚ the bowed heads of the potato pickers suggest the

Potato Osmosis Introduction: A shipwrecked sailor is stranded on a small desert island with no fresh water to drink. They know they could last without food for up to a month‚ but if they didn’t have water to drink they will be dead within a week. Hoping to postpone the inevitable‚ their thirst drives them to drink the salty seawater. They are dead in two days. Why do you think drinking seawater killed the sailor faster than not drinking any water at all? Today we explore the cause of the sailor’s

potential of a potato Aim Osmosis is the movement of water molecules from a region of high water concentration to a low water concentration through a semi-permeable membrane. Our aim is to investigate the water potential of a potato through osmosis‚ by finding the difference in weight before and after the potato has been set in a solution of water‚ sugar or salt. Trial Method Firstly we collected the equipment. This included a scalpel‚ potato cutter‚ and test tubes. Then we cut the potato using the

Aim The aim is to find the concentration (mole/dm3 (M)) of solute in a potato cell by using the process of osmosis and different concentrations of sucrose solution. Background information Osmosis is diffusion of water across a partially permeable membrane. It moves from a solution with less solute concentration (high water potential) to a solution with more solute concentration (low water potential). The one with a high water concentration is called a hypotonic solution and the low water concentration
