  2. 6. Studies of the fragmentation process in hadronic decays of Z⁰ boson

    Author : Oxana Smirnova; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fragmentation; gluon; QCD; hadron calorimeter; DELPHI; LEP; accelerator; particle; Fysik; Physics; Bose-Einstein correlations; Fysicumarkivet A:1996:Smirnova;

    Abstract : This thesis is based on the work that was done during 1992--1996 at the DELPHI detector at LEP. Its main parts are outlined below. The brief Introduction gives an overview of the science of Particle Physics, its development and contemporary status. READ MORE

  4. 7. Studies of Molecular and Cluster Fragmentation Using Synchrotron Radiation: Measurements and Models

    Author : Andreas Lindgren; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atom- och molekylärfysik; Atomic and molecular physics; photoionization; synchrotron radiation; localized excitation; electron-ion coincidence; induced alignment; clusters; molecules; core excitation; mass spectroscopy; fragmentation; dissociation;

    Abstract : A new spectrometer for studying photoinduced fragmentation has been designed and commissioned. The instrument produces a detailed view of the energy and angular emission of fragments, which in the case of small molecules can be related to their geometry at the moment of dissociation.

  5. 8. Mehanics of Rock Fragmentation Static and Dynamic Laboratory Testing Applied to Aggregate Production

    Author : Bahman Bohloli; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anisotropy; aggregates; rock failure; saturation; Brazilian test; dynamic tensile strength; Hopkinson pressure bar; fragmentation; rock fines; crushing;

    Abstract : Knowing the strength properties of rocks is essential for calculating the stability of natural slopes, constructions in and on rock, excavations, blasting geometry, crushing, and drilling. When rock and rock masses are subjected to either dynamic or static loads, the tensile strength is determined by tests appropriate to the load type. READ MORE

  6. 9. Ritualization - Hybridization - Fragmentation : The Mutability of Roman Vessels in Germania Magna AD 1–400

    Author : Fredrik Ekengren; Institutionen för arkeologi och antikens historia; []
    Keywords : HUMANIORA; HUMANITIES; ritual destruction; obolus; imports; Roman Iron Age; Roman vessels; Germania Magna; transformation; appropriation; practice theory; ritual practice; princely graves; fürstengräber; identity construction; silver vessels; Germanic pottery; hybridity; Roman glass; Charon s coin; fragmentation; enchainment;

    Abstract : This PhD thesis deals with the transformation of imported vessels of Roman origin in Germania Magna during the Roman Iron Age, 1-400 AD. The concept of transformation in this context refers to the various ways these objects were interpreted, physically altered and consequently changed with regard to their function and meaning.

  7. 10. Molecular Hole Punching : Impulse Driven Reactions in Molecules and Molecular Clusters

    Author : Michael Gatchell; Henning Zettergren; Henrik Cederquist; Henning Schmidt; Joachim Burgdörfer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PAHs; Fullernes; Reactions; Clusters; Interstellar Medium; Fragmentation; Non-Statistical Fragmentation; Collisions; Experiments; Molecular Dynamics; Density Functional Theory; fysik; Physics;

    Abstract : When molecules are excited by photons or energetic particles, they will cool through the emission of photons, electrons, or by fragmenting. Such processes are often thermal as they occur after the excitation energy has been redistributed across all degrees-of-freedom in the system. READ MORE
