...For example, fabrics that have been in contact with chlorine bleach must be avoided according to Welter and Curto, as silver chloride forms over silver coins, making them turn black. The effects of chlorine would negatively impact Kennedy half dollar coins produced before 1970, but would only have small impacts on coins made after 1970, as these minted coin do not contain silver. The 1980 coin which contains nickel, instead of silver, is more durable. Nickel is the hardest coinage metal, and it does not oxidize or tarnish so...

...in 1964 and 1965 (the ‘Official Tie Tack Pin’) was by Press Initial Corp of Rhode Island and fully authorized by NEMS and Selteab. There were at least six different styles made at this time, four of them featured the head of either John, Paul, George, or Ringo. These had the designation of “Official Tie Tac Pins” and most had the additional verbiage “by Press-INitial Corp. ©1964 NEMS Enterprises Ltd”. Some had an added disclaimer “Manufactured under license from Seltaeb Inc. The ONLY official licenses with exclusive rights to the manufacture and distribution of Beatle Tie Tac Pins”.

...Chapter 3 Introduction to Microcontrollers 3.1 Just a Start Up A microcontroller (also MCU or ¥ìC) is a computer-on-a-chip. It is a type of micro-computer element that emphasizing high integration, low power consumption, self-sufficiency and cost-effectiveness, in contrast to a general-purpose microprocessor. In addition to the usual arithmetic and logic elements of a general purpose microprocessor, the microcontroller typically integrates additional elements such as read-write memory for data storage, read-only memory, such as flash memory for code storage and permanent data storage memory, peripheral devices, and input/output interfaces. Microcontrollers often operate at very low speed compared to modern day microprocessors, but this is adequate for many typical applications. They consume relatively little power (milliwatts), and will generally have the ability to sleep while waiting for an interesting peripheral event such as a button press to wake them up again to do something. Power consumption while sleeping may be just nanowatts, making them ideal for low power and long lasting battery applications. Microcontrollers are frequently used in automatically controlled products and devices, such as automobile engine control systems, remote controls, office machines, appliances, power tools, and toys. By reducing the size, cost, and power consumption compared to a design using a separate microprocessor, memory, and input/output devices, microcontrollers make it...

...I park my car a few metres away from the nest and get out of the car. I slide on my black leather, fingerless gloves whilst walking towards the factory. It was very old as dust collected around every window seal and crevasse. All the windows were border up with nails and thick planks of wood, that looks somewhat new against the ancient factory. The sun starts to set and the light gradually drains away. As I approach the doors I reach into my pocket and grab a bobby pin. I bend it back and duck down to rest on my knee while I unpick the lock. Using the bobby pin the door clicks open and stays ajar. I push the door open revealing an old, dusty and gloomy room packed with small machines. Vast sunlight pours in through the cracks of the windows...

...common computer abbreviations and acronyms Content Summary Major Components in the System Unit Case A computer case is the enclosure that contains the main components of a computer. The size and shape of a computer case is usually determined by the form factor of the motherboard. In computing, "form factor" is an industry term for the size, shape and format of computer motherboards, power supplies, cases, and add-on cards. Most desktop computers have a form factor that is some variant of ATX. A case designed for an ATX motherboard and power supply may take on several external forms, such as a vertical tower (designed to sit on the floor, height > width) or a flat desktop (height < width). Computer cases usually include: sheet metal enclosures for a power supply unit and drive bays; a rear panel that can accommodate peripheral connectors protruding from the motherboard and expansion slots; a power button, a reset button, and LEDs to indicate power status as well as hard drive and network activity. Major component locations * The motherboard is usually screwed to the case along its largest face, which could be the bottom or the side of the case depending on the form factor and orientation. * Form factors such as ATX provide a back panel with cut-out holes to expose I/O ports provided by integrated peripherals, as well as expansion slots which may optionally expose additional ports provided by expansion cards. * The power supply unit is often housed at the...

...of the Bridge Pod. Then, the Bio Amp cable was attached to the Bio Amp socket on the PowerLab. The three lead wires were attached to the Bio Amp cable. Other materials such as dissecting dish, metal pins, scissors, forceps, strong thread with a barbless hook, acetylcholine solution, epinephrine solution, and Frog Ringer's solutions in cold, warm, and room temperature were collected. The force transducer was zeroed by adjusting the baseline value to zero. A weight between 5 and 50 grams was hanged from the force transducer and was recorded for five seconds to calibrate the force transducer. The N value was calculated and the calibration was implemented. A double-pithed frog was dissected by making a longitudinal and lateral incision along the ventral surface of the abdomen with scissors. The tissue and the sternum was cut away to expose the thoracic cavity. The pericardium was cut away with the forceps to expose the heart. The force transducer was attached to the heart by lifting up the apex of the heart and piercing it with a hook. The tension on the thread was adjusted and the thread was left perpendicular to the table, instead of an angle. The lead wire alligator clips were attached to the pins holding the frog to record the ECG.
