A brief history of diving The first recorded incidence of diving comes from ancient Greece (1), divers jumped into the water carrying a 15kg stone, sank to around 30 metres and cut the sponges away from the sea bed.Sound travels much faster and further in the sea, this confuses the brain and means that sounds can appear to be all around a diver as the brain can only detect distance and direction of sounds by the time difference that they are detected in each ear, as the sounds travel much faster, the brain thinks that the sound must be all around, sounds also travel much further in water that in air, so quiet sounds are amplified and can lead to disorientation.As a diver descends through the water, the pressure increases on their body, a...

If you have to carry more water than usual, you can take a plastic bladder from boxed wine.It can even be used to store extermination, water, or other small items that the officer may need to keep handy.My mind is brimming up with innovative backpacking ideas as I write this article on backpack with wheels.All you need is a remove its soft removable covering to use a two-in-one water container/pillow.This gives your camera a 100% protection against any water.

The reflected amount of light is partly polarised horizontally and partly enters the water vertically.The blue color travels across the longest in the water due to its shortest wavelength.Another main concern is related to the water that bends the light either to make crinkle patterns or to diffuse it.Most importantly, the quality of the water controls and influences the filtering properties of the water such as sprinkle of the dust in water.Light attenuation limits the visibility distance, at about twenty meters in clear water and five meters or less in turbid water.

There were also an experiment done on how to purify our drinking water and what water had the most contaminants in it.beakers with Tap water, Dasani, and Fiji, and pour 100ml of each type of water into the beakers name.Based on the results of all three experiments, there were many observations and data provided such as for experiment 1: In beaker (1) the water were clear with no odor, beaker (2) water were cloudy with the oil sitting on top of the water with no odor, beaker (3) water had a slight odor, and in beaker (4) water were cloudy with a light green color with a pleasant smell with bubbles on top of the water.The results of experiment 3 the drinking water quality were tested with three different types of water using tap water, Das...

Two millimeters of sterile water were added to the filter paper to maintain moisture.The dilute spore suspension of each isolate collected from different geographical regions was prepared in sterile distilled water and from this, two ml of spore suspension was spread uniformly on water agar plates and excess suspension was drained off aseptically from the plates.The healthy young (3-6days) leaves of susceptible cashew were collected and washed in sterile water.The samples were rinsed in sterilized distilled water, dried with sterile tissue paper, placed inside plastic boxes (30 × 15 × 10 cm) lined with moist filter papers, and axially marked with black permanent ink.In control, the leaves were inoculated with sterile distilled water.
