Abstract:
Using the stabilized jellium model (SJM) in two schemes of "relaxed" and "rigid", we calculate the dissociation energies and the fission-barrier heights for the binary fragmentations of singly-ionized and doubly-ionized Ag clusters. In the calculations, we assume spherical geometries for the clusters. Comparison of the fragmentation energies in the two schemes show differences that are significant. This result reveals the advantages of the relaxed SJM over the rigid SJM in dynamical processes such as fragmentation. Comparing the relaxed SJM results and experimental data on fragmentation energies, it is possible to predict the sizes of the clusters just before their fragmentations.

Full text
Abstract:
Twelve 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)-pyridinones were investigated by tandem mass spectrometry using positive as well as negative electrospray ionization. The influence of the electron affinity of the substituent and the steric effect on the fragmentation is discussed. Pyridinones with a substituent of low proton affinity show loss of water, HCN or benzene from the pyridinone ring in the first step of MS2 fragmentations. Oppositely, if a substituent with high proton affinity is present on the phenyl ring in the 4-position of pyridinone, the fragmentation paths are complex, depending mainly on the substituent proton acceptor ability. Elimination of neutral molecules CO, HCN, H2O, PhH (benzene) or Ph and CN radicals are fragmentation processes common for all compounds in the subsequent steps of the fragmentations.

Full text
Abstract:
C—C bond cleavages of radical cations of 2-substituted benzothiazoline derivatives were investigated to determine the parameters controlling the fragmentation rate constants. In spite of the low oxidation potentials of the compounds, fragmentation rate constants greater than 1 × 106 s–1 could be achieved through weakening of the fragmenting bond by substituents that stabilize the radical fragment and exert steric crowding. A quantitative assessment of the relative roles of radical stabilization vs. steric effects to weaken the fragmenting C—C bond was achieved through DFT calculations. The calculated activation enthalpies matched reasonably well with the experimentally determined values. A thermokinetic analysis revealed that the fragmentations of benzothiazoline radical cations have relatively large intrinsic kinetic barriers, ascribed to the delocalized nature of the product radical and cation fragments. Interestingly, the same factors that lead to the large intrinsic barriers led, simultaneously, to large thermodynamic driving forces for the fragmentations, which should lead to lower activation barriers. These effects oppose each other kinetically and provide important insight into the design of fast radical ion fragmentation reactions.Key words: benzothiazoline, radical cation, fragmentation, steric effects, DFT.

Abstract:
The azaspiracids, AZA1, AZA2 and AZA3, are the predominant shellfish toxins responsible for the human toxic syndrome, azaspiracid poisoning. Collision induced dissociation (CID) mass spectra were generated for azaspiracids using nano-electrospray ionisation (ESI) with a hybrid quadrupole time-of-flight (QqTOF) mass spectrometer in positive mode. Six main backbone fragmentations of the polyether skeleton of azaspiracids were observed as well as multiple neutral losses of water molecules from the parent and product ions. The characteristic charge-remote fragmentation of the carbon skeleton of azaspiracids produced nitrogenous ions. The three azaspiracids differ from one another by 14 Da due to methylation in the A- and E-rings. Three fragmentation pathways, involving cleavage of the E-ring, C27–C28 and G-ring, gave ions that were common to all azaspiracids. Another three fragmentations involving the A-ring, C-ring and C19–C20, were useful for distinguishing between azaspiracid analogues. Multiple tandem ion‒trap mass spectrometry (MSn) was used to confirm the fragmentation pathways.

European Journal of Mass Spectrometry 11, no. 1 (February 2005): 31–34. http://dx.doi.org/10.1255/ejms.709.

Full text
Abstract:
Five peptide thioesters of increasing length were fragmented using two processes, in-source and in-collision cell fragmentation, using an electrospray source coupled to a triple quadrupole mass spectrometer. Comparison of their fragmentations was made in regard to their length. The two fragmentation conditions show that the peptide length has no influence on structural information and that the fragmentation efficiency is higher for the smallest peptides than for the longest. The particularity of these peptide thioesters consists of the neutral loss of ethanethiol. The absence of the a3 fragment ion and the presence of the (a3–17) ion on the collision-induced dissociation mass spectra are noted.

Abstract:
This qualitative research sought to do a comparative analysis of social fragmentation in Things Fall Apart and Maru. Textual analysis was employed to analyse, interpret and evaluate the two novels in the light of postcolonial criticism, focusing on otherness. The researchers engaged the texts in multiple readings to gain a descriptive understanding of them and take descriptive notes at every stage of reading. Excerpts were purposefully sampled from the novels and analysed thematically. The study revealed that in pre-colonial Africa, social fragmentation resulted from classism, patriarchy and bad tradition; hence, the society operates in a binary relationship. In colonial Africa, social fragmentation resulted from religion and racism. However, post-colonial Africa experienced the deepest form of social fragmentation; spiced by tribalism and other pre-colonial factors. The study concluded that both novels confirm the concept of ‘otherness’. So, future research can focus on emotional and structural fragmentations.

Abstract:
Rationale: The term “fragmentation of the QRS complex” denotes the existence of high-frequency potentials (spikes) in the QRS-complex. It is either a marker for cardiac structural diseases inducing biventricular hypertrophy or any condition interfering with the normally homogeneous depolarization status inside the myocardium. An associated right ventricular infarction with inferior infarction maybe carry a risk impact and serious complications. Patient concerns: A 64-year-old married, farmer, heavy smoker, Egyptian male patient presented with acute severe chest pain and inferior with right ventricular ST-segment elevation myocardial infarction and fragmentation of the QRS complex. Diagnosis: QRS-complex fragmentations and right ventricular infarction in the presence of inferior infarction with the triple-vessels disease. Interventions: Electrocardiography, oxygenation, streptokinase intravenous infusion, echocardiography, and percutaneous transluminal coronary angioplasty. Outcomes: Dramatic response of acute inferior with right ventricular ST-segment elevation myocardial infarction and QRS-complex fragmentations to streptokinase. Lessons: Despite the presence of inferior and right ventricular ST-segment elevation myocardial infarction with QRS-complex fragmentations, but there is no correlation with the severity of the disease. Dramatic clinical and electrocardiographic response signifying the role of streptokinase and fibrinolytic. The presence of fragmentation of the QRS-complex may have a bidirectional impact from seriousness to complications.

Abstract:
"Fragmentation" désigne une mise en rapport de la peinture, gravure et sérigraphie modulant une fascination pour Pinocchio. "A l'oeil", "à d'autres", "à l'oeuvre", et "au plaisir", ces quatre tomes précisent chacun un regard. A l'oeil. Peine perdue d'avance : comment taire le commentaire que les pièces provoquent ? A d'autres. Le centralisme de la personne n'est pas étranger aux rapports exacerbés aux maîtres, meurtriers et endettés, que des monstres indiquent. Puisque l'invention s'avère constituée d'emprunts, il faut substituer à "l'auteur" l'éloge de l'échange, beaux-arts et arts et métiers confondus. A l'oeuvre. "L’ergologie" (de l'unité d'enseignement et de recherche du langage à Rennes 2) interpelle le plasticien puisqu'elle vise à transposer analogiquement à l'art l'analyse propre au langage. A la réduction de l'activité aux moyens et aux fins auxquels correspondraient peinture, gravure, sérigraphie, dans le rapport à Pinocchio, il faut substituer la dualité des qualités et des quantités, et de deux manières : - par le fragmentant, non seulement il n'y a pas de "matière première", mais celle-ci est à prendre comme produit d'une élaboration- fragmentation en qualités utiles et en ustensiles; - par le fragmenté, en dissociant le fait de l'effet et le fabriqué de l'intention, pour reconnaître les potentialités créatrices des dispositifs impliqués, toujours déjà choisis et ordonnés en opération et appareillages. Au total, le rendement de la fragmentation réside dans l'interférence de pratiques "socio artistiquement" séparées puisqu'il n'y a pas de qualité ni de quantité qui n'y soit indifféremment productive. Au plaisir. Investissements de l'affectivité dans la conduite active plus que dans la conscience parlée, les dispositifs de fragmentation sont alors coupures et sutures. Face au vide de l'excision, le questionnement est module, entre la réticence d'un graveur et l'appétit effréné d'un peintre. Non plus "le sens" mais la perte à renouveler de l'image métamorphique de Pinocchio légitime diversement des iconoclasmes, dont la plastique, scandaleusement indifférente. Relier ainsi une plastique de la fragmentation à des visées différentes, c'est indiquer une mobilisation de l'art par des rapports conflictuels
"Fragmentation" designates the setting up of a relationship between painting, engraving and serigraphy, modulating a fascination for Pinocchio. "To the eye", "To others", "To the work", "To pleasure", each of these four volumes emphasizes a specific look. To the eye. To no avail : how to silence the comments that the works provoke? To others. The centering of the person is not alien to the exercerbated relationships, murdering and endebted to masters, that monsters indicate. Since invention proves to be made of borrowing, one must substitute for "the author" the praise of exchange, beaux-arts and arts and crafts taken together. To the work. Ergology (in the language and cultural sciences department of the University of Rennes 2) questions the graphic artist since it aims at transposing analogically the language analysis to art. To the reduction of activity to means and ends, to which would correspond painting, engraving and serigraphy-in relationship to Pinocchio - , one must substitute the duality of qualities and quantities in two ways : - through the "fragmenter" : not only is there no "raw material", but the latter is to be considered as a product of an elaboration-fragmenta- tion into useful qualities and utensils; - through the "fragmented" : in parting the fact from the effect, the fabricated from the intention, to recognize the creative potential of implied devices, always selected beforehand and arranged as to operations and tools. To sum up, the productivity of fragmentation lies in the interference of practices politically separated since quality and quantity are undifferentiately productive. To pleasure. Investments of affectivity in active conduct, more than in spoken conscious- ness, the fragmentation devices are therefore composed of ruptures and sutures. In the face of the emptiness of the excision, the questioning is modulated between the reticence of the engraver and the gluttony of the painter. No longer the "meaning", but the loss to be renewed of the metaphoric image of Pinocchio, diversely legitimates the iconoclasms, among which are graphic arts, scandalously indifferent. To link thus an esthetics of fragmentation to dif- ferent aims, is to stress a mobilisation of art through conflicting relationships

Abstract:
This thesis deals with fragmentation of complex molecular ions, especially biomolecules, in gas phase collision experiments. The aim is to investigate the relations between energy deposition and fragmentation and to shed light on the mechanisms behind energy and charge transfer processes in collisions involving the building blocks of life. Further, the question how a solvent environment influences the dissociation behavior is elucidated. In the first part of the thesis, results from different collision experiments with biomolecular ions are presented, focusing on electron capture induced dissociation of hydrated nucleotides and small peptides. The investigated processes may be relevant for the understanding of radiation damage and the optimization of sequencing methods used in protein research. Our results clearly demonstrate that effects due to surrounding solvent molecules are substantial. While the dissipation of internal energy by evaporation of the loosely bound solvent molecules may protect the biomolecule, the influence which this environment has on the electronic structure may lead to an enhancement or suppression of certain dissociation channels. The second part of the thesis focuses on recent instrumental developments. Here, the aim was to optimize and complement the techniques used in the experiments above and to have versatile tools available for different kinds of gas phase collision studies involving complex molecular ions. Therefore, we have constructed an electrospray ion source platform for the preparation of intense beams, with options of accumulation and cooling of mass selected ions, allowing for a large variety of experiments. This device is also intended to serve as an ion source for the new storage ring facility DESIREE (DoubleElectroStatic Ion Ring ExpEriment), which is currently under construction at Stockholm University. In these unique storage rings, oppositely charged ions may interact at very low relative velocities in a cryogenically cooled and ultrahigh vacuum environment.

Abstract:
Findings through fragmentation Architecture is an obvious remnant of our collective past and gives us a fragment of a former life and a different time. This unique relationship between what’s new and old is a very powerful spatial opportunity. If memory is defined as ‘The faculty by which the mind stores and remembers information’ then the role of architecture comes to play is the prop for our collective and individual memories where it represents past events and people.  If we look closely at the definition of a fragment without it's context it will be read as ‘incomplete’ and subordinate to the completed it is extracted from. Architectural fragments have a power of resisting such expected unity and can be read into an alternative whole of none. By fragmenting industrial buildings that is going to b demolished, representing a time and a group of people in Lövholmen/Stockholm, I wish to embody memory and recall spaces that will be forever lost.
Rummet mellan det som är och det som har varit Arkitektur representerar vår historia och det kollektiva minnet.  Att minnas definieras som ‘förmågan att lagra erfarenheter och göra det möjligt att känna igen och lära’. Minnen placerar oss i förhållande till tid och rum vilket gör att platser och arkitektur kommer att spela en stor roll som bärare av vår kollektiva historia. Byggnader som bär spår av tid där de har varit grunden i en annan kontext kan utgöra ett unikt möte mellan det rum som existerar och det som har varit.  När vårt medvetna väljer ut och sorterar bland minnen fragmenteras det som vi upplevt och bara vissa delar finns kvar. Fragment kan definieras som en pusselbit som tillhört en helhet och blivit en spillra. Styrkan i arkitektonisk fragment är att de kan läsas på nya sätt efter att det isolerats från en helhet och antingen läsas in i en ny kontext eller ingen. Genom att fragmentera byggnader som representerar en specifik tid och grupp av människor som har använt dom vill jag förkroppsliga dessa rumsliga minnen innan de för alltid går förlorade.

Abstract:
In order to characterize the relationship between hydrodynamic and thermal fragmentation of molten metallic fuels with the interaction of the coolant of sodium in the wide range of thermal and hydrodynamic conditions, the present paper focuses on a series of fragmentation experiments of a single molten copper droplets (1∼5 g) with wide ambient Weber number (102 ∼ 614) and superheat condition (15 ∼ 574 °C), which penetrated a sodium pool. The intensive fragmentations of single molten copper droplets were clearly observed even at the instantaneous contact interface temperatures (Ti) below the melting point besides higher Ti. The size distributions of molten droplet with high Weber number somewhat incline to be less than those with low Weber number in the same thermal condition. When approximately Wea>200, the effect of hydrodynamic fragmentation becomes predominant over that of thermal fragmentation in the low superheat condition. In the high Weber number or high superheating condition separately, the size distributions of the single metal droplet and jet reported by Schins’ group with different mass of thousand times can keep very similar. Moreover, the values of Dm/D0 must be quite small. The relatively larger size distributions of the single metal droplet and the jet reported by Nishimura et al. will only arise in the both low Weber number and low superheating condition.

Abstract:
Numerical simulations of explosive fragmentation munitions presented in this work integrate three-dimensional axisymmetric hydrocode analyses with analytical fragmentation modeling. The developed analytical fragmentation model is based on the Mott’s theory of break-up of cylindrical “ring-bombs” (Mott, 1947), in which the average length of fragments is a function of the radius and velocity of the ring at the moment of break-up, and the mechanical properties of the metal. The fundamental assumption of the model is that the fragmentation occurs instantly throughout the entire body of the shell. Adopting Mott’s critical fracture strain concept (Mott, 1947), the moment of the shell break-up is identified in terms of the high explosive detonation products volume expansions, V/V0. The assumed fragmentation time determined from the high-speed photographic data of Pearson (1990) had been approximately three volume expansions, the fragmentation being defined as the instant at which the detonation products first appear as they emanate from the fractures in the shell. The newly developed computational technique is applied to both the natural and preformed explosive fragmentation munitions problems. Considering relative simplicity of the model, the accuracy of the prediction of fragment spray experimental data is rather remarkable.
