  2. Multimodal transport - Wikipedia

    en.wikipedia.org/wiki/Multimodal_transport

    Multimodal transport (also known as combined transport) is the transportation of goods under a single contract, but performed with at least two different modes of transport; the carrier is liable (in a legal sense) for the entire carriage, even though it is performed by several different modes of transport (by rail, sea and road, for example).

  3. Triplestore - Wikipedia

    en.wikipedia.org/wiki/Triplestore

    A triplestore or RDF store is a purpose-built database for the storage and retrieval of triples [1] through semantic queries.A triple is a data entity composed of subject–predicate–object, like "Bob is 35" (i.e., Bob's age measured in years is 35) or "Bob knows Fred".

  4. Quadruple bond - Wikipedia

    en.wikipedia.org/wiki/Quadruple_bond

    This bond is an extension of the more familiar types of covalent bonds: double bonds and triple bonds. [1] Stable quadruple bonds are most common among the transition metals in the middle of the d-block, such as rhenium, tungsten, technetium, molybdenum and chromium. Typically the ligands that support quadruple bonds are π-donors, not π ...

  5. Cross-link - Wikipedia

    en.wikipedia.org/wiki/Cross-link

    Chemical reactions associated with crosslinking of drying oils, the process that produces linoleum.. Crosslinking generally involves covalent bonds that join two polymer chains.

  6. Triple point - Wikipedia

    en.wikipedia.org/wiki/Triple_point

    The term "triple point" was coined in 1873 by James Thomson, brother of Lord Kelvin. [2] The triple points of several substances are used to define points in the ITS-90 international temperature scale, ranging from the triple point of hydrogen (13.8033 K) to the triple point of water (273.16 K, 0.01 °C, or 32.018 °F).

  7. Nucleic acid tertiary structure - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_tertiary...

    The first adenine of the GAAA sequence forms a triple base-pair with the receptor AU bases. The second adenine is stabilized by hydrogen bonds with the same uridine, as well as via its 2'-OH with the receptor and via interactions with the guanine of the GAAA tetraloop. The third adenine forms a triple base pair.

  8. Single bond - Wikipedia

    en.wikipedia.org/wiki/Single_bond

    A covalent bond can also be a double bond or a triple bond. A single bond is weaker than either a double bond or a triple bond. This difference in strength can be explained by examining the component bonds of which each of these types of covalent bonds consists (Moore, Stanitski, and Jurs 393). Usually, a single bond is a sigma bond.

  9. Simple Lie group - Wikipedia

    en.wikipedia.org/wiki/Simple_Lie_group

    Once these are known, the ones with non-trivial center are easy to list as follows. Any simple Lie group with trivial center has a universal cover whose center is the fundamental group of the simple Lie group. The corresponding simple Lie groups with non-trivial center can be obtained as quotients of this universal cover by a subgroup of the ...
