Buoyancy

Elements for his own work ("Niccolo Tartaglia"). Tartaglia also translated many of Archimedes’ works into Latin, which made it easier for European mathematicians to access them. Tartaglia’s translation of Archimedes’ work included the equation for buoyancy as well as formulas for finding the area and volume of spheres, cylinders, and other geometric shapes…

From Theory to Practice The following case studies were conducted at an interactive science museum, the Discovery Center of Springfield, located in southwestern Missouri. The Discovery Center is a hands-on museum that regularly serves around 100,000 visitors annually in addition to offering distance learning opportunities and outreach to the surrounding communities. The facility represents one of the only educational spaces of its kind serving the region. The museum comprises around 60,000…

Is the Glass Actually Half-Full? Is the glass half-empty or half-full? An age old question that reveals how one views the world. Everyone faces conflict, and can approach it in many different ways. Some methods work better than others, but one way proves to have the most beneficial results. “Anne Frank: The Diary of a Young Girl” and “Blood, Toil, Tears, and Sweat” are two great selections that prove that conflict is best faced with a positive attitude. Facing conflict with optimism inspires…

Did you notice the boy walking down the hall today with sulking shoulders? His eyes piercing through the hallway floor, his head constantly dropped? Or what about that girl crying in the bathroom all by herself. Perhaps the overweight boy who is always by himself and the foreign girl who always wears long sleeves because she slit her wrists the night before? Did you notice them or did you walk past them like you do everyday? Those rare moments you do catch a glimpse at their faces, did you…

The Southern Bog Lemming is native to Ottawa, Canada and is often found in bogs, moist places, and sometimes deciduous forests and meadows. Lemmings are small mouse-like animals that on average weigh 35 grams. The dorsal side tends to be dark brown while the ventral side is a silver-ish gray. Algonquin Wolf The Algonquin Wolf is native to Ottawa, Canada and is a hybrid of the Eastern Wolf, Gray Wolf, and Coyote. Algonquin Wolves are usually found in, but not limited to, deciduous and mixed…

LIPLESS CRANKBAITS -- DEADLY FOR SPEED FISHING Rat-L-Traps, Cordell Hotspots, Sugar Shads, etc. Great lures for all kinds of gamefish, but highly underrated for muskies. These baits can be especially effective on spring or early fall muskies cruising overtop weed flats. Like all lures, specific situations exist where these lures really produce. Personally, I really like these kind of baits whenever muskies are average in size, but high in numbers, and are cruising overtop shallow weed cover…

The purpose of experiment six was to better understand how to measure and read volumetric flow rate of water through a pump, and to better understand how flow meters work. In this experiment, the relationship of the plot between the orifice and Venturi meter pressure differential showed many correlation with each other. The volumetric flow rate had a square root relationship with the previous stated pressure differentials. The error in this lab was also extremely low appearing at around…

Many have enjoyed Self-Contained Underwater Breathing Apparatus (SCUBA) diving as an exciting recreational sport for many years. Though SCUBA diving is a very rewarding experience, a diver must be sufficiently trained before entering a potentially dangerous situation. Divers must have an understanding of SCUBA from both a scientific and recreational view, along with ample training, to properly use equipment and prepare for potential hazards. Prolonged underwater experiences have fascinated…

A fluid in which the viscous stresses taken place from its flow at all the point are linearly proportional to the rate of change in its deformation over time is called Newtonian fluid. Newtonian fluid explains the relationship between the shear rate and the shear stress is linear with the proportionality constant, which is to be referred as the coefficient of viscosity. Non-Newtonian fluid is a fluid where the properties of fluid flow are not similar with Newtonian fluid. In Newtonian fluids,…

INTRODUCTION Oral Controlled Release Drug Delivery Systems1, 2: Oral controlled release drug delivery is a drug delivery system that provides*give the continuous oral delivery of drugs at predictable and reproducible kinetics for a predetermined period throughout the course of GI transit and also the system that target the delivery of a drug to a specific region within the GI tract for either local or systemic action. All the pharmaceutical products formulated for systemic delivery via*throw…
