JOINT BASE ELMENDORF-RICHARDSON -- Soldiers from the 4th Quartermaster Detachment conduct combat water survival training at Buckner Physical Fitness Center, JBER-Richardson, Sept. 1. Training included treading water for 5 minutes, completion of two separate 25 meter swims, one with rucksack and then M-4 Carbine, making of flotation devices from the Army Combat Uniforms, and finally a 3-meter platform dive and 25-meter swim with their weapons.

This long strand of kelp with its flotation device still attached probably broke free at the root or anchor which sent it to the surface and onto the rocky beach of Beachcomber Regional Park on the north side of Northwest Bay.
Though I haven't tried it, I understand that this kelp would be ready to eat and that there is no need to soak it or cook it. This Pacific sea plant may be used as a salad ingredient, or in soups, also with rice or pasta and even pizza. These kelp fronds are rich with minerals and vitamins.
As I am about to embark on a journey over water, I thought I would leave you with this image.
Don't really know why this title came to mind.
Maybe because these are the last things you might want to use to keep you afloat.
Just a thought.
Happy Thanksgiving to All!

Like the American Coot, the aquatic Sensitive Plant has adapted to living on water. The Coot has "floating feet" and the Sensitive Plant has "floating stems." Unique flotation material similar to soft styrofoam surrounds its floating stems. Yes, Mother Nature is quite the adaptive creator!
As their name describes, Sensitive Plant's thin, narrow leaves close slowly when touched.
At night they also fold up. Yellow flowers are feathery balls. Grows quickly in warm weather. Does not tolerate cold. Pretty and different; fascinating to kids and adults.
This pond plant is also called the Catclaw mimosa. Sensitive plants grow to a height of 5" and spreads to 34". Sensitive plant is a native plant of the US. The sensitive plant should be used as an annual pond plant. This floating plant propagates by seed or by cutting. Sensitive plant blooms in summer with yellow pea like flowers. Set in the pond when the water has reached 69º. This floating plant needs full sun to partial shade. Plant has yellow flowers in summer. This plant should be planted in soil 2"-7 inches deep but can be floated on the water's surface. Zones 5-11.

Tanks, in theory, can go anywhere, which is why they are fitted with tracks. However they can be defeated by deep water unless landing craft or rafts are available. The idea of an amphibious tank, especially one that will float without the aid of temporary flotation devices, has attracted designers for many years. Vickers-Armstrongs built an amphibious light tank between the wars which enjoyed some modest export success, notably in Russia where it was copied, and this was even tested by the British Army.
The light tank L1E3, which appeared in 1939, was produced specifically to British War Office requirements. Most of its mechanical features are identical to contemporary Vickers light tanks but the hull is surrounded by aluminium floats, filled with kapok, to provide buoyancy. Two marine propellers, shrouded in steering cowls, are fitted at the back but driven by shafts from the front sprockets. The tank was even equipped with a small boat anchor at one time.
The truly amphibious tank is a contradiction in terms to some extent. If it is light enough to float it must have dangerously thin armour. If it is adequately protected it will probably be to heavy to float. Such tanks normally perform well on land, due to their light weight, and if properly designed can swim well in the water. Their greatest problem is getting out of the water, especially on muddy river banks. This design was never adopted. The tank was tested briefly at the start of the war, spent the next four or five years in reserve and was then subjected to more tests after the war, by which time it was completely out of date.

Columbia floated down under its 3 orange & white parachutes, hitting the water just before dawn and coming to rest in a Stable 2 (upside down) position. The astronauts triggered the release of the three flotation bags, which righted the CM in about 7 minutes. The first member of the UDT-11 recovery team jumped from helicopter #64 into the water and attached a sea anchor to the CM to keep it from drifting. Three more UDT swimmers then jumped in and attached the flotation collar to stabilize the CM in the choppy water. They inflated and positioned two life rafts - one for biological decontamination and the other for helicopter hoist operations. Text from www.uss-hornet.org/history/apollo/

"This is NOT a Personal Flotation Device" by Pate Conaway. Photo by Robert Banke, NIU Media Services.
Materials are sent to hopper of rotary dryer by belt conveyor or bucket elevator. The barrel is installed with slope to horizontal line. Materials enter the barrel from the higher side, and hot air enters the barrel from the lower side, materials and hot air mix together. Materials go to the lower side by gravity when the barrel rotates. Lifters on the inner side of barrel lift materials up and down to make materials and hot air mix completely. So drying efficiency is improved.
Rotary drier Description:
Rotary drier is widely used for drying materials in industries like cement, mine, building materials, chemistry, food and fertilizer, etc. This rotary drying machine comes with thermocouples on the feeding and discharging device to control the temperature. Thermometers are also adopted so as to better control the working temperature (generally 350-380°) of the rotary drier.
Rotary Sand Dryers are provided with automatic temperature, pressure and electrical controls, with burner systems capable of firing natural gas, propane and/or oil. Direct heat Rotary Sand Dryers are available in sizes ranging from 6" to 156" in diameter and lengths from 3' to 100'.
The wet material is fed into one end of the rotating cylinder where longitudinal parallel lifting fights pick up the material and cascade it in thin even sheets so that it will dry most advantageously. Usually as the material dries, its angle of repose changes. To accommodate this change, the lifting flight sections differ in size and shape, thus assuring optimum heat transfer at all points within the dryer.
Rotary Dryer Components:
Rotary drier is mainly composed of cylinder, under frame, feeding and discharging devices, transmission device, gear cover, etc. (Optional auxiliary equipment includes combustion chamber, feeder and discharging device, and dust collection equipment). Rotary drier manufactured by us adopts new lifting plate, which is of functions like guiding, current-sharing, and material raising. The materials are raised and evenly drop so that they are in full contact with heat for better drying efficiency. Our rotary drier is designed with the best working conditions, which enables it to save 10-15% of energy and increase 10-15% of productivity compared with common dryers.
Rotary cylinder dryer Applications:
A dryer is a kind of mechanical equipment which uses heat energy to reduce the water content of materials.
Industrial drying equipment is mainly used in building materials manufacturing, metallurgy and chemical industry, and cement production industry, etc. to dry mineral slag, limestone, coal powder and clay, etc.
If used in combination with our coal gasifier, our dryer can also be used for fine chemical drying.
Our industrial dryers are also regularly used in compound fertilizer production lines.

Our Daily Challenge ... watch your step.
Rock fishing is probably the most dangerous sport in Australia. Each year an average of 20 people drown while fishing from rocks and ledges because of the unpredictability of the waves and rock surfaces which are often very uneven and slippery. A fall or a freak wave can result in the fisherman ending up in the water and unable to get out. Always wear a personal flotation device and never fish alone.
This tailings pond is next to the Continental Mine in Butte, Montana (= “Richest Hill on Earth”; = "The Mining City"). The Butte Mining District has produced gold, silver, copper, molybdenum, manganese, and other metals.
The area's bedrock consists of the Butte Quartz Monzonite (a.k.a. Butte Pluton), which is part of the Boulder Batholith. The Butte Quartz Monzonite ("BQM") formed 76.3 million years ago, during the mid-Campanian Stage in the Late Cretaceous. BQM rocks have been intruded and altered by hydrothermal veins containing valuable metallic minerals - principally sulfides. The copper mineralization has been dated to 62-66 million years ago, during the latest Maastrichtian Stage (latest Cretaceous) and Danian Stage (Early Paleocene). In the supergene enrichment zone of the area, the original sulfide mineralogy has been altered.
The Continental Mine was started in 1980 by the Anaconda Copper Mining Company - it is currently owned by Montana Resources. The mine targets a low-grade copper and molybdenum deposit on the eastern side of the Continental Fault, a major Basin & Range normal fault in the Butte area with about 3500 feet of offset. The mine's rocks consist of BQM with disseminated copper sulfides, plus copper- and molybdenum-bearing hydrothermal veins that intrude the BQM. Minerals at the site include chalcopyrite, molybdenite, malachite, azurite, tenorite, and cuprite. The latter four minerals are secondary copper minerals, produced by alteration of the primary copper sulfides.
In 2010, the Continental Mine was making 50,000 to 52,000 tons of ore each day. This mine can operate down to an ore grade of 0.1% copper. Most of the mineralization is disseminated copper, but veins are also present. Two stages of mineralization occurred in the Butte area - a porphyry copper system and a main stage system with large veins. The bottom of the porphyry copper system is ~ less than 12,800 feet below the surface. Veins peter out at 5600 to 5800 feet below the surface. At the Continental Mine, veins are small - they're veinlets less than 6 inches wide.
Mining is done 24 hours a day, 365 to 366 days per year. There's 1 to 2 days of down time at the mill. During those days, mining stops and waste material is moved. The ore:waste ratio is 8:10 (= strip ratio). The alluvial overburden consists of 7 paleosol horizons, including some caliches - the lime content results in an average pH of 8. The caliche material can be used to treat acidic materials.
The mine has 14 shovels and 15 trucks. A large Bucyrus shovel can load a 240-ton truck in three passes. The mine's benches are forty feet tall. Blasting is done with ANFO - ammonium nitrate and fuel oil. 0.65 pounds of explosives are used per ton of rock. The mine uses ~45 megawatts of power per day, which is about the same as the city of Butte itself.
Continental Mine ores are crushed in two stages. The crushed ores are then sent to the mill, where they are ground down to the fineness of talcum powder. Flotation and lime are used in processing. Sulfides are collected. 1% of the mined material goes to the concentrator. 99% of mined material becomes tailings. The tailings powder is wet (33% solid and the rest is water) and piped uphill to a pond. The tailings pond water has a pH of 10. Water from the pond is recycled to make tailings slurry. 27 million gallons a day enters the pond. An earthen dam around the pond is designed to withstand a powerful earthquake.
Copper and molybdenum concentrates produced at the Continental Mine are not smelted locally - they are not even smelted in America. Concentrates are sold around the world, where material is smelted and the metals are produced. America shipping rocks overseas and buying back the finished product is the behavior of an underdeveloped country - America is not interested in smelting anymore - a sad reality.
