  • history of underwater diving

    the history of underwater diving starts with freediving as a widespread means of hunting and gathering, both for food and other valuable resources such as pearls and coral, by classical greek and roman times commercial applications such as sponge diving and marine salvage were established, military diving also has a long history, going back at least as far as the peloponnesian war, with .

  • tire manufacturing

    belts give the tire strength and dent resistance while allowing it to remain flexible. passenger tires are usually made with two or three belts. tread. the tread is a thick extruded profile that surrounds the tire carcass. tread compounds include additives to impart wear resistance and traction in addition to environmental resistance.

  • tire-pressure monitoring system

    a tire-pressure monitoring system tpms is an electronic system designed to monitor the air pressure inside the pneumatic tires on various types of vehicles. a tpms reports real-time tire-pressure information to the driver of the vehicle, either via a gauge, a pictogram display, or a simple low-pressure warning light.tpms can be divided into two different types – direct dtpms and indirect .

  • damp proofing

    integral damp proofing in concrete involves adding materials to the concrete mix to make the concrete itself impermeable. 3 surface suppressant coating with thin water proof materials such as epoxy resin for resistance to non-pressurized moisture such as rain water or a coating of cement sprayed on such as shotcrete which can resist water under pressure.

  • abrasion mechanical

    abrasion is the process of scuffing, scratching, wearing down, marring, or rubbing away. it can be intentionally imposed in a controlled process using an abrasive. abrasion can be an undesirable effect of exposure to normal use or exposure to the elements.

  • period 5 element

    rubidium is the first element placed in period 5. it is an alkali metal, the most reactive group in the periodic table, having properties and similarities with both other alkali metals and other period 5 elements.for example, rubidium has 5 electron shells, a property found in all other period 5 elements, whereas its electron configuration's ending is similar to all other alkali metals: s 1.

  • dredging

    the dredged material is usually sucked up by a wear-resistant centrifugal pump and discharged either through a pipe line or to a barge. cutter-suction dredgers are most often used in geological areas consisting of hard surface materials for example gravel deposits or surface bedrock where a standard suction dredger would be ineffective.

  • tire manufacturing

    tread compounds include additives to impart wear resistance and traction in addition to environmental resistance. tread compound development is an exercise in compromise, as hard compounds have long wear characteristics but poor traction whereas soft compounds have good traction but poor wear characteristics. cushion gum

  • list of diving hazards and precautions

    divers face specific physical and health risks when they go underwater with scuba or other diving equipment, or use high pressure breathing gas.some of these factors also affect people who work in raised pressure environments out of water, for example in caissons.this article lists hazards that a diver may be exposed to during a dive, and possible consequences of these hazards, with some .

  • damp proofing

    damp proofing or a damp-proof in construction is a type of moisture control applied to building walls and floors to prevent moisture from passing into the interior spaces. dampness problems are among the most frequent problems encountered in residences.

  • bicycle tire

    the tan colored, natural rubber lacks carbon black to decrease rolling resistance, as its added wear resistance isn't needed in the sidewall. skin wall. tires with very little rubber, if any, covering the sidewall are called 'skin wall'. this reduces rolling resistance by reducing sidewall stiffness at the cost of reducing damage protection.

  • jameson cell

    the new slurry lens design had a smooth, shallow entry angle that created an optimum flow regime over the ceramic, reducing wear and extending its life. the shape resulted in a decrease in power consumption by the feed slurry pump by up to 10% and resulted in better jet formation that improved air entrainment.

  • natural rubber

    natural rubber is often vulcanized - a process by which the rubber is heated and sulfur, peroxide or bisphenol are added to improve resistance and elasticity and to prevent it from perishing. carbon black is often used as an additive to rubber to improve its strength, especially in vehicle tires, which account for about 70% 9 million tons of carbon black production.

  • asphalt

    slurry seal involves the creation of a mixture of asphalt emulsion and fine crushed aggregate that is spread on the surface of a road. cold-mixed asphalt can also be made from asphalt emulsion to create pavements similar to hot-mixed asphalt, several inches in depth, and asphalt emulsions are also blended into recycled hot-mix asphalt to create .

  • rust

    rust is an iron oxide, a usually red oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture. several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances. rust consists of hydrated iron iii oxides fe 2 o 3 ·nh 2 o and iron iii oxide-hydroxide feo .

  • atmospheric diving suit

    an atmospheric diving suit ads is a small one-person articulated anthropomorphic submersible which resembles a suit of armour, with elaborate pressure joints to allow articulation while maintaining an internal pressure of one atmosphere.the ads can be used for very deep dives of up to 2,300 feet 700 m for many hours, and eliminates the majority of significant physiological dangers .
