    As a leading system supplier for fastening and assembly technology and as an international service provider, Böllhoff is a recognised partner for automotive and aeronautics manufacturers.

    During the JEC World 2018, Böllhoff has showcased a part of its fastening offers dedicated to composite applications :
    - ONSERT® – Fast bonding of fasteners using light-curing adhesives
    - IMTEC® HR – High mechanical resistance fastener for in-moulding processes
    - RIVKLE® SFC (Smart For Composite) – Blind rivet nut for composite materials

    Capitalizing on its long experience in the development of composite assembly solutions (ONSERT®, RIVKLE® SFC, etc.), Böllhoff took up a new challenge by proposing an innovative cold-forged fastener: IMTEC® HR. This is a high mechanical resistance fastener that has been designed for in-moulding structural and semi-structural applications in automotive industry such as openings (tailgates, doors, hinges…), composite floors and seat structures. It is a lightweight, optimized performance / cost composite solution for automotive industry.



    Origin of life. Mathematician A.E.Zlobin deduced this mathematical expression, which seems in good agreement to V.I.Vernadsky’s ideas concerning origin of life. The most wonderful property of this mathematical expression is that the factor j=1.0079… simultaneously coincides to the value of atomic mass of hydrogen with high accuracy.

    1.0079… – “irrational one number” (for the first time was suggested by A.E.Zlobin)
    1.6180… – “golden ratio” or “extreme and mean ratio”
    2.7182… – “Napier number”
    3.1415… – “Ludolph number”

    This expression may be used as system of measurements (metrics) for analysis of atoms. It seems very convenient, because all values during such analysis will be relative. Due to the metrics of atom of hydrogen the interaction between atoms may be presented as simple analogue of thinking. Pattern recognition algorithm here is possible which based on strongly mathematical laws.

    More detailed information about Zlobin’s formula is in the paper – Tunguska similar impacts and origin of life, August 7, 2013, (arxiv.org/abs/1402.1408), Cornell University Library [ pdf ].
    Also you can find there the description of deduction of the metrics with the help of Fibonacci row of numbers.
