was to improve or maintain a blood pressure of 120/80 or less. Goal: The goal in this case is to maintain a systolic pressure (upper number) at the January level of 116 or no greater than 120‚ while lowering the diastolic pressure (lower number) to below 80 by way of increased physical activity. Results: Initial results showed an increase rather than a decrease in diastolic pressure. Mode of activity was changed/modified‚ with the return of diastolic pressures to 80. The conclusion is increased

failed to find anything out of the ordinary. This only increased my paranoia even more. I felt as though I was fighting a war with the darkness‚ darting from one trench to the next‚ fleeing for my life. I groped around the darkness to find the light switch on my bedside lamp. I flipped the light... Light... Safety. I immediately felt relieved. I listened carefully for any noises. I could only hear the buzz of electricity in the light above me that gave me a sense of safety‚ and the beating of my

Negative Impact of Technology ’Technology and threats have a lot in common.’ The negative impact of technology on society has left no stone unturned in proving this statement right. Let’s get acquainted with more in the following write-up... It is appallingly obvious our technology has exceeded our humanity. ~ Albert Einstein When I was a kid‚ we had a social life‚ and it was called ’outside’. And look at today’s kids - Facebook‚ PlayStations‚ iPhones‚ Blackberries‚ and not to forget‚ television

Fiber Optic Safety Rules 1) Keep all food and beverages out of the work area. If fiber particles are ingested they can cause internal hemorrhaging 2) Do not smoke while working with fiber optic systems. 3) Always wear safety glasses with side shields. Treat fiber optic splinters the same as you would glass splinters. 4) Never look directly into the end of fiber cables until you are positive that there is no light source at the other end. Use a fiber optic power meter to make certain the

Literature Survey IC 4066 The 4066 chip is a Quad Bilateral Switch that can be used with digital or analog signals. Transistor BC148 It’s a plastic version of a standard NPN Transistor and is used for small signal general purpose amplification. SPST Switch (Single Pole‚ Single Throw) A Simple on-off switch: The two terminals are either connected together or disconnected from each other. An example is a light switch.

clear back to 0. This clock is also equipped with an alarm. With a super bright LED to display the alarm. 7485 comparators were used to detect when the alarm time is reached. The alarm is set with DIP switches corresponding to each bit. A SPDT switch is in place to set the alarm to on. An LED indicates when the time set on the alarm is reached regardless if the alarm is set to on. When the alarm time is reached the outputs of counters and the outputs of the DIP switches are equal and the A=B

the circuit will be complete. The third part is the spring. The spring pulls the armature back after the power is shut off. The fourth part is the source of power which supplies the power needed for the relay to work. And finally the fifth part is a switch or button which turns on the power. Those are the essential parts to a relay. The relay has very little power as I told you earlier‚ but the armature raises the amount of power. For example the coil can energize two hundred fifty milliwatts. When

capacitor is used with a resistor in a timing circuit. A variable capacitor is used in a radio tuner. Switches (SPST & SPDT) SPST SPDT SPST = Single Pole‚ Single Throw. An on-off switch allows current to flow only when it is in the closed (on) position. SPDT = Single Pole‚ Double Throw. A 2-way changeover switch directs the flow of current to one of two routes according to its position. Some SPDT switches have a central off position and are described as ’on-off-on’.
