1.0 Introduction to Cellular Communications Mobile Communications Principles Each mobile uses a separate‚ temporary radio channel to talk to the cell site. The cell site talks to many mobiles at once‚ using one channel per mobile. Channels use a pair of frequencies for communication one frequency (the forward link) for transmitting from the cell site and one frequency (the reverse link) for the cell site to receive calls from the users. Radio energy dissipates over distance‚ so mobiles must stay

Stress and Cellular Membranes Bio Lab SBI 4U1 Due: Sept 24th‚ 2010 For: Ms. Barton By: Ameema Saeed Introduction: (See attached lab) Purpose: (See attached lab) Hypotheses: Tap water will cause no damage to the membranes. The extreme temperatures of the water cooled to 0°C‚ and heated to 94-100°C will greatly damage the membranes. Extreme heat will be more damaging than extreme cold. The more concentrated the solvent‚ the more damage it will cause to the membranes‚ therefore the

Brand Update : Idea Idea cellular is running another series of campaigns under " An idea can change your life " theme. This time‚ the brand is evangelizing " save the trees " idea. Watch the tvc here : Idea Idea cellular should be commented for its consistency in their positioning. It is very easy for the brand managers to become bored at harping on same theme again and again. This can prompt some managers to change for the sake of changing thus undoing the entire work done so far. In that

Cellular adaptations occur in terms of: * size of the cells that are atrophy decrease in cell size due to decrease workload; and hypertrophy due to increase workload * number of the cells that is are hyperplasia(but this is one change) increase in the # of cells resulting due toform increase rate of cell division due to injury or hormones. * reversible change of one type of cell into another type of cell that is metaplasia occurs due to chronic inflammation and irritation. * disordered

Cellular Reproduction Cellular Reproduction is the process by which all living things produce new organisms similar or identical to themselves. This has to happen because if a species were not able to reproduce‚ that species would quickly become extinct. Reproduction consists of a basic pattern: the conversion by a parent organism of raw materials into offspring or cells that will later develop into offspring. The reproductive process‚ whether asexual or sexual always involves an exchange

Redox Titration Lab ABSTRACT: In this lab‚ 0.010 M purple-colored potassium permanganate solution was standardized by redox titration with iron (II) ammonium sulfate hexahydrate (FAS). The average mass of the three flasks of FAS was 0.483 grams. Once the concentration of the standard solution of KMnO4 (aq) was determined‚ it was used to determine the concentration of Fe2+ in iron pills. On average‚ there was 0.01813 L of solution used. With this information and the balanced net-ionic equation

Lab 3: Mitosis and Meiosis Purpose: The purpose of this lab was to recognize the stages as well as events of mitosis and meiosis in a plant cell or an animal cell. The relative duration of each stage in the cell cycle will also be learned during this lab. By doing this lab we will also create a model of and understand the process of crossing over. This lab also helps students understand the similarities along with differences between mitosis and meiosis. Hypothesis: I predict that
