www.galacticfriends.com On behalf of the Galactic Federation and the Spiritual Hierarchy, we greet you. We would like to assure you that we are of the Light, and that we come to you in the service of your Creator to assist and advise you so that you may better understand and react to the changes which will soon be upon you and your planet. With your limited vision, and your relationship with self-centeredness and conflict, you may be tempted to suspect that we have come to harm or to conquer you. There are indeed forces in your universe who might have such intentions. But their powers have been largely neutralized at this time. I have already assured you and gladly assure you once again that we are of the Light, and that we are here for your benefit. The time has now come for a general movement upwards, a sorting of those who are ready to move up, and those who are not. Your planet is to be cleansed physically as well as on the spiritual level, for she has suffered much harm in acting as your host. It is important that you have some idea of what lies immediately ahead and why it is to take place, so that you may prepare yourselves. This is our first task. You have collectively made great advances in science and technology, but in so doing, you have often neglected another important source of information, namely your intuition. In your obsession with things physical, things which can be seen, felt, measured and tested, you have gained the impression that if you cannot see ...
This video shows two experiments that help explain why and how an oil spill on the seafloor, similar to the current BP leak in the Gulf of Mexico, could form underwater oil plumes that do not rise to the surface. The reasons include: •whether a spill is released in the form of a turbulent jet, or is under less pressure •the density of the surrounding water, due to temperature and salinity. In both tests, the tank contains salt water that's denser at the bottom than at the top (bottom 1.06 g/cc, top 1.015g/cc). The first video shows a green-colored alcohol/water mixture being released into the tank; the second experiment shows red gauge oil being released. Both the oil and alcohol mixtures are about the same density (approximately 0.9g/cc) and are released at the same rate (about 0.8 gallons/minute). As you can see, the first more turbulent jet is trapped underwater in a horizontal plume when it reaches the level where the surrounding water density changes; the second less turbulent jet is not trapped, and the oil rises to the surface. The experiments were conducted by Richard McLaughlin, Ph.D., and Roberto Camassa, Ph.D., fluid dynamics experts in the mathematics department at the University of North Carolina at Chapel Hill "We've been thinking that the recent news about underwater oil plumes is very reminiscent of these jet experiments, in which the effect of the strong turbulence is creating an emulsion which can lead to an underwater trapping," McLaughlin said. "In ...
Oil spill, my Idea is to create a strong water whirl to contain the oil in the center. The Oil has a lighter density than water and therefore should remain at the center of whirl while the water is expelled in the opening between the Bottom Hat and the Top Hat. The power of the 3 water pumps (or submarine propellers) is controlled by an operator on a ship, watching at all time what is going on through a video cam. A Heater in the ''pump box'' will warm up the water to avoid any ice formation. I hope this could help...
The coin is weighed in air then weighed in water and a ratio is calculated. Each metal has an exact specific gravity. Relative density, or specific gravity,[1][2] is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. The term "relative density" is often preferred in modern scientific usage. The density of substances varies with temperature and pressure so that it is necessary to specify the temperatures and pressures at which the densities or weights were determined. It is nearly always the case that measurements are made at nominally 1 atmosphere (101.325 kPa the variations caused by changing weather patterns) but as specific gravity usually refers to highly incompressible aqueous solutions or other incompressible substances (such as petroleum products) variations in density caused by pressure are usually neglected at least where apparent specific gravity is being measured. For true (in vacuo) specific gravity calculations air pressure must be considered Aluminum2.70 Zinc7.13 Tin7.31 Iron7.87 Cobalt8.9 Nickel8.9 Copper8.96 Molybdenum10.22 Silver10.49 Lead11.36 Palladium12.02 Mercury13.55 Uranium18.95 GOLD19.32 Tungsten19.35 Plutonium19.35 Neptunium20.2 Rhenium21.04 Platinum21.45 Iridium22.4 Osmium 22.6 Greek crisis may derail global economic recovery www.commodityonline.com
Stenosis / narrowing shown experimentally in fluid filled silicone tube. Simple experiment to show how dissolved substances--salts, sugars, metals and minerals, found in the blood and all body fluids assist circulation due to the affect of gravity on density imbalance due to evaporation from the breath, respiratory tract, skin, eyes and hair. My website: www.andrewkfletcher.com My Blog www.inclinedtherapy.com This flow and return system shown experimentally in open-ended soft wall silicon tubing filled with water suspended 2 metres vertically by the centre with both open ends immersed in the water filled bottles, one of which has yellow food colouring added to show a return flow and to show clearly the narrowing caused by the tension applied to the water inside the tube and bottles. Red coloured saline is introduced at the top of the suspended loop of tubing via a T junction and a syringe body to initiate the flow and return circulation, red representing the arterial blood flow in humans and all animals. And the phloem vessels in plants and trees. Yellow representing the venous return flow and the xylem return flow in plants and trees. One of the objectives of the experiment is to show how solutes dense substances alter the fluid tension on the inside walls of the silicon tubing filled with water, which is by no means as pliable as the majority of veins in the human body. At the same time showing how increasing the density of the fluids at the upper part of the experiment ...
You get to the river and find conditions are not as you expected, the wind is full in your face. If there are fish rising, don't turn round and fish the wet fly. Chances are you will do poorly, as you will not present your fly properly due to drag caused by the the wind going with the current. Downstream wet or dry fly in a downstream wind can be even more difficult in these conditions. Better to face the challenge of the wind in your face and fish your fly into the wind. This clip shows how the forward power stroke is set at a steeper angle than normal, then adjusts on delivery to a shallower delivery angle. The wind helps to load the rod on the back cast as you drive the line back rapidly aided by the wind. Making a tight forward wind cheating loop, aided by a little left hand line haul follows on relatively easily. Keep the back cast high and adjust the angle of the cast by lowering your casting arm slightly on delivery so that the forward cast develops just above the water. The wind is always less strong just above the surface of the water. The wave action and friction created on the wind/water boundary layer - where wind meets water breaks down the wind density at water level, allowing you to deliver your fly with authority into the wind.

Something I've been thinking about/designing. I've tried to simplify it as much as possible. Looking for input/discussion/thoughts. To recap: potential energy in battery to electricity through water to potential energy as hydrogen and oxygen is a closed system where all energy from the battery ends up stored as energy in the gases. However, when the water is converted, it creates a potential gravitational energy since it's less dense now than the water surrounding it. When the less dense ...
Pumice rock, also known as volcanic bomb, is the only rock that can float on water, because it has a low enough density. When the magma that forms pumice rock erupts it does so violently which causes it to fly up high, cool quickly, and have a lot of gas dissolve in it and escape again. This results in a rock that is very porous and so it has a lot of empty space in its volume which causes it to have a low enough density to float on water.
