  • golf

    golf is a club-and-ball sport in which players use various clubs to hit balls into a series of holes on a course in as few strokes as possible.. golf, unlike most ball games, cannot and does not utilize a standardized playing area, and coping with the varied terrains encountered on different courses is a key part of the game.the game at the usual level is played on a course with an arranged .

  • tin

    tin forms several inter-metallic phases with lithium metal, making it a potentially attractive material for battery applications. large volumetric expansion of tin upon alloying with lithium and instability of the tin-organic electrolyte interface at low electrochemical potentials are the greatest challenges to employment in commercial cells.

  • lugworm

    the lugworm or sandworm arenicola marina is a large marine worm of the phylum annelida. its coiled castings are a familiar sight on a beach at low tide but the animal itself is rarely seen except by those who, from curiosity or to use as fishing bait , dig the worm out of the sand.

  • tillage

    tillage is the agricultural preparation of soil by mechanical agitation of various types, such as digging, stirring, and overturning. examples of human-powered tilling methods using hand tools include shoveling, picking, mattock work, hoeing, and raking.examples of draft-animal-powered or mechanized work include ploughing overturning with moldboards or chiseling with chisel shanks .

  • soil

    in areas of extreme rainfall and high temperatures, the clay and humus may be washed out, further reducing the buffering capacity of the soil. in low rainfall areas, unleached calcium pushes ph to 8.5 and with the addition of exchangeable sodium, soils may reach ph 10. beyond a ph of 9, plant growth is reduced.

  • aquifer

    an aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials gravel, sand, or silt . groundwater can be extracted using a water well.the study of water flow in aquifers and the characterization of aquifers is called hydrogeology.related terms include aquitard, which is a bed of low permeability along an aquifer, and aquiclude or aquifuge .

  • tunnel boring machine

    a tunnel boring machine tbm , also known as a 'mole', is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata.they may also be used for microtunneling.they can bore through anything from hard rock to sand.tunnel diameters can range from one metre 3.3 ft done with micro-tbms to 17.6 metres 58 ft to date.

  • heavy crude oil

    heavy crude oil or extra heavy crude oil is highly-viscous oil that cannot easily flow to production wells under normal reservoir conditions.. it is referred to as 'heavy' because its density or specific gravity is higher than that of light crude oil.heavy crude oil has been defined as any liquid petroleum with an api gravity less than 20 . physical properties that differ between heavy .

  • tibesti mountains

    the tibesti mountains are a mountain range in the central sahara, primarily located in the extreme north of chad, with a small extension into southern libya.the highest peak in the range, emi koussi, lies to the south at a height of 3,445 metres 11,302 ft and is the highest point in both chad and the sahara. bikku bitti, the highest peak in libya, is located in the north of the range.

  • pottery

    however, the lowest quality common red clay was adequate for low-temperature fires used for the earliest pots. clays tempered with sand, grit, crushed shell or crushed pottery were often used to make bonfire-fired ceramics because they provided an open-body texture that allowed water and volatile components of the clay to escape freely. the .

  • henry vacuum

    henry was also one of the first vacuums to use microfiber dust bags, which are large capacity dust bags known as hepa-flo bags, and are made of a strong material that carries dust and other unwanted materials into them and retains them unlike any paper bags which tend to rip and leak dust. since the introduction of henry in 1981, it has sold 7 .
