In September of 1969, I was five years old, and I started to attend kindergarten. This was the first school year for the newly organized Mid-Valley School District. The new proper name of our school was the Olyphant Elementary School, but we commonly referred to it as the Mid-Valley Elementary School in Olyphant. My classroom was in the part of the building that used to be the Olyphant Central School; the part that was dedicated in 1910. This was the same school building in which my great-uncle John and my grandfather attended seventh and eighth grade. My father attended the tenth through twelfth grade in this building as well. Albeit, they had classes in the annex. The Olyphant Elementary School was a majestic brownstone building with ivy climbing the exterior walls. There was pipe fencing along the walkways to prevent people from going onto the lawn. The school was fortress-like in appearance. On the corner of the lawn, just inside the fence near the flagpole, there was a howitzer and a monument that looked like a tombstone. It looked like the howitzer was there to defend the school. We were told that it was used in the war. Even though at the time the United States was involved in the Vietnam War, whenever our teachers said the war, they meant World War II. There was one kindergarten classroom in our school. We had half-day kindergarten. The students who lived in the Grassy Island, Fern Hill, and Smoketown sections of Olyphant (side of the railroad tracks…
transferred to the round-bottom flask (RBF) using the plastic funnel. Three milliliter of tert-butyl methyl ether and two or three boiling chips were added into the flask. The black plastic connector was used just like the distillation column with air condenser set-up. The flask was clamped to the ring stand using 3-pronged clamp. The flask was lowered into a slightly depression in the sand without touching directly to the sand. The mixture was then boiled gently at the boiling point for 10…
Something pulls at my heart when I look into the stars. Something in the great beyond pulls at me, calling me, begging me to claim it as my own. Something in the great nothingness that envelopes our tiny planet is beckoning me. Maybe it’s nothing. Maybe it’s a fool’s hallucination, the manifestation of a child’s dream. Maybe it is a call that was meant to be answered by men and women far greater than I’ll ever be. Maybe the signal got lost on it’s way to find Earth’s next great hero and instead…
instruments. Each one varies due to the certain make and model of the vehicle with the different variations on the particular vehicle. Take a truck for instant it has a speedometer, tachometer, and transmission temperature gauge. Due to the fact that it will be towing a heavy object and be putting stress on the motor, so it doesn’t get too hot the gauge is there to protect it. Now on a sport car your two main instruments will be the speedometer and the tachometer. The speedometer is there to…
The light began to flicker. She rotated to the light switch gently. Nobody was there. Maybe the light bulb is loose, she thought to herself. She pranced upon her bed, which was beneath the light, and tried to screw in the light bulb a bit more. there was nothing wrong with the light bulb. She tilted her head in confusion. Maybe it gave out, she convinced herself. Wait didn’t I just change it today? Her thoughts commenced to gallop wildly in her head. Suddenly, there was a deep chuckle in the…
Imagine waking up at sunrise and tucking in your bed at sunset. Then, after many years, while striking stones, you discover fire, something that would help you stay awake at night in presence of light. Burning firewood and lighting up oil lamps remained sources of light until the Nineteenth century when the Incandescent light bulb was co-invented by two scientists - Thomas Edison and Joseph Swan. Since then, the lightbulb has been the invention of the 19th century that has shined on us for…
Q4) How do you to test the following equipment is functioning correctly prior to use and how can you tell when it does not? What action would you take if the equipment failed? a) Dental chair We are testing chair practically every day when we are switching chair on. If the chair is not moving we checked the main switch on the side at the bottom, if the pressure is on in bottle with water for procedures and if the switch over the table with computer is on. If all is on and chair is still not…
Salcha-1 was incubated in six Erlenmeyer flasks (1L) containing 200mL of Potato Dextrose Broth (10g/L Great Value mashed potatoes with 5g/L D-glucose). One of the five flasks received approximately 1.0-1.3g of the following metal compounds: cobalt (II) chloride hexahydrate, cobalt (II) nitrate hexahydrate, cobalt (II) thiocyanate, erbium chloride hexahydrate, or palladium (II) acetate. The sixth flask was reserved as a control and only contained PDB. Salcha-1 was incubated on an Innova 5000…
They added about 20 mL of deionized water to the salt and stirred the solution until it dissolved. As it dissolved, the solution turned into a light blue color. Then to make sure that very little of the solution was left on the stirring rod, they rinsed it with more deionized water into the beaker. After thoroughly rinsing a 50-mL volumetric flask with deionized water, they transferred the solution into this flask and rinsed the 100-mL beaker with deionized water in order to ensure as much of…
Methods: To begin, our group acquired three premade vials of .1ml mammal blood with coagulant. We then labeled the vials numbers one, two, and three. In vial number one we added 1 ml of Stock 300 mM NaCl, and no distilled water. This resulted in a NaCl concentration of 1.8 percent. In the second vial we added .5 ml of Stock 300 mM of NaCl, and .5 ml of distilled water. This resulted in a NaCl concentration of .9 percent. In the third vial we did not add any Stock 300 mM of NaCl, and 1 ml…
