Buoyancy

Ningaloo Reef Marine Ecosystem 1. Identify ten organisms from your chosen ecosystem and draw a food web to show trophic interactions between them. Within this food web, you must include and label a decomposer. Ten organisms that live in the Ningaloo Reef include the bottlenose dolphin, loggerhead turtle, tiger shark, whale shark, Southern Calamari squid, jellyfish, zooplankton, dugong, phytoplankton and seagrass. The decomposer in this food web is bacteria, which works to further break down…

What is Styrofoam? Styrofoam is a brand of closed-cell extruded polystyrene foam currently created for thermal insulation and craft applications. Dow Chemical Company retained and produced the Styrofoam. Through petroleum product known as styrene, Styrofoam was created. The styrene is amended into a clear molten mass of polystyrene through a complex chemical process known as polymerization. It would become a hard plastic if it were left to cool. Disposable eating utensils are created from this…

meters, the plastron can collapse, letting water penetrate into the feather structures. Properly aligned feathers will not allow water or air to penetrate, and ensure that the bird is buoyant and insulated from the cold. Oiled birds lose their natural buoyancy from air pockets created by proper feather alignment, and they can sink and drown in polluted waters. This may be because they still have detergent on their feathers. A small misalignment from detergent can also cause birds to lose…

Along with the weight gain, swollen ankles and strange cravings, you may experience a variety of aches and pains during pregnancy. Back pain is a common complaint from pregnant moms. This pain is commonly due to the expanding uterus that stretches the abdominal muscles, shifts the center of gravity and places pressure on the lower back. Fortunately, there is no reason to suffer in pain for nine months. Try these three tips to save your back and enjoy your pregnancy. 1. Exercise There are…

Following the civil war, the railroads towards the west helped in opening up a lot of land for settlement and economic development. White settlers traveled from the East to farm, ranch, and mine. Along with the white settlers, African- Americans made their way from the south to the west for economic development. Even the Chinese who worked on the railroads traveled to the west furthering its diversity. Settlers from the east changed the face of the “Great Plains”. Buffalo and cattle that lived…

What's to know about that lonely planet on the far reaches of our solar system? More than you'd think. It turns out Pluto spits out a fair bit of news on the reg so listen up. Here are five things ignorant Earthlings don't know about the planet. 1. PLUTO IS COLDER THAN WE THINK AND WE DONT KNOW WHY The upper atmospheric temperature of the planet has been found to be much colder than any Earth-based studies have previously found. About 70 degrees Fahrenheit colder actually. That's news to a lot…

Physical therapy is a vital part of a successful surgery but patient compliance is essential.9 After surgery, the physical therapy will progress in four phases.9-10 Initially, the repair and tendon need to be protected.9-10 This generally involves immobilizing the joint in a sling for 4-6 weeks after surgery.9-10 The length of time the joint is immobilized depends on what type of surgery was performed. 9-10 During phase I the patient will be introduced to prophylactic active motion at the elbow,…

For them, capture efficiency equals the ratio of the captured flow rate to the total plume flow rate at the range hood. A year later Li et al [2] also argued that design methods or kitchen hood analyses that do not use the buoyancy capture principle will not produce very meaningful results. Other published experimental studies such as Farnsworth et al. [3] Singer et al. [4] and Rim et al. [5] show that capture performance increases with increase in suction flow rate and that…

In order to float, they use tiny air bubbles to provide them with buoyancy. Another way they move is with their sail. Most are “left- handed” with a sail that runs along the body from upper- left to lower- right. Some do have sails that run from upper- right to lower- left though. Because of these sails, they only sail…

The third trimester is a period of excitement and anticipation about your little one’s arrival. At the same time, the thoughts of labor and delivery scare you. Staying active throughout these nine months help you sail through the delivery with ease. As you enter the third trimester, your growing belly restricts you from doing certain exercises. Safety is also a concern during this time. Here are a few third trimester exercises which are safe and helpful for mom and baby. 1.Walking And Jogging…
