Nuclear motion in molecular ions studied with synchrotron radiation and multicoincidence momentum imaging spectrometry

A momentum imaging spectrometer optimized for photoionization experiments with synchrotron radiation was built in 2008. The spectrometer is equipped with an electrostatic lens, that focuses the charged dissociation products on to a position-sensitive multi-hit delay line anode. The possibility of focusing is essential for most applications, where fragment momentum is to be extracted. The apparatus is equipped with a micro-channel-plate detector opposite to the delay line anode, enabling electron-ion coincidence experiments and thereby mass-resolved ion spectroscopy independent of the time structure of the synchrotron radiation. Calibration and characterization of the instrument is explained. Results for the photo-fragmentation of several molecules are presented, including measurements of kinetic and angular distributions as well as momentum correlations between coincident fragments. Various data analysis methods are described. High sensitivity of the instrument enables detection and analysis of weak processes such as isomerization. Full three-dimensional momentum information for each coincidence event is achieved which allows for in depth understanding of geometry, dynamics and energetics. In Ethyne, molecules with a cis-bending motion has been identified. In carbonyl sulfide and carbon dioxide, the Renner-Teller splitting has been analyzed. For the water molecule, transient isomerization has been found to be induced by strong bending vibrations in core-excited states. Also studies have been made on clusters, displaying the capability of the instrument to measure a large range of masses and kinetic energies

Prediction of outcome after abdominal aortic aneurysm rupture

This thesis aims to examine the validity of existing tools recommended for outcome prediction after abdominal aortic aneurysm (AAA) rupture and to design and validate a novel risk scoring instrument. It also aims to examine the utility of novel predictive variables. Finally, it examines the functional outcomes achieved by survivors of aneurysm rupture.Existing risk models and predictive variables for outcome were validated on a retrospective cohort of consecutive patients with ruptured AAA. These data were also used to design a novel prognostic index for outcome prediction. A prospective cohort of consecutive patients was used to further validate these scoring systems, examine novel prognostic variables and determine functional outcome.Existing risk scoring instruments for patients with ruptured AAA lack validity. Analysis of preoperative variables in patients with ruptured AAA shows that absolute surgical futility cannot be predicted. However, in-hospital hypotension (<90mmHg), reduced Glasgow Coma Scale (<15) and anaemia (<9g/dL) are associated with perioperative death. When these risk factors are equally weighted and combined to create a novel risk scoring instrument (Edinburgh Ruptured Aneurysm Score-ERAS), three discriminatory tiers of risk are demonstrable. The validity of this risk instrument is confirmed on prospective data. Examination of novel perioperative prognostic variables shows that elevated cardiac troponin I, with or without clinically apparent cardiac dysfunction, is predictive of death after ruptured AAA repair. However, although ruptured AAA are associated with an early elevation in inflammatory biomarkers, these do not appear to confer additional prognostic value. Furthermore, for the first time, prospective study shows that patients who survive ruptured AAA repair achieve a good recovery in terms of functional outcome within six months of operation.Surgical futility cannot be predicted prior to operation in patients with AAA. However, the ERAS shows potential as a preoperative prognostic index in patients with ruptured AAA

MEDIA FRAMING ON ONLINE NEWS HEADLINES IN REGARDS TO THE GILETS JAUNES PHENOMENON

Gilets Jaunes massive protest in France was considered as the most serious crisis in the Fifth Republic since the protest of May 1968. The importance of the event was such that it generated serious controversy, which was widely reported and many French media competed to highlight the development of the action group. This study examines the headlines of the Gilets Jaunes phenomenon in two online news sites (LeFigaro.fr and Libération.fr) with a different ideology. The analysis was carried out using theories of Le Querler's syntactic structure, Nida's meaning componential analysis, Dor &amp; Gattani's headline functionality, and Entman's media framing. The results show that left-wing media news titles framed Gilets Jaunes as evidence of the people's struggle, while the right-wing media framed Gilets Jaunes as an action that only caused riots and casualties

The construction and meaning of EasyJet airline 2016 advertisements

EasyJet, a UK low-cost airline service provider launched several attractive advertisements to attract consumers' interest, one of which is a series of posters issued in 2016. These posters are interesting because the words show complex morphological processes and implied meanings that can be extracted. Previous studies have mostly examined morphological formation or have conducted semiotic studies, but none have linked morphological processes and images on posters with a semiotic approach. Therefore, this study analyzes the word formation process in the 2016 EasyJet advertisement, which has undergone a derivation process, and finds out the meaning contained in the advertisement using a semiotic approach. This qualitative study examines the posters based on Lehmann and Berthet’s (2018) theory of word formation and Barthes' (2013) semiotics theory. The result of this study indicates that in this advertising poster, EasyJet attracts people to use its services in several market segments or consumer groups according to their respective characteristics. The stratagem revealed through these posters is that EasyJet is an airline that wants to invite its prospective passengers to explore new activities.Konstruksi dan makna iklan maskapai EasyJet tahun 2016EasyJet, salah satu perusahaan penyedia jasa penerbangan berbiaya rendah (LCC) asal Inggris yang menyediakan layanan penerbangan berbiaya rendah, meluncurkan beberapa iklan menarik untuk menarik minat konsumen, salah satunya adalah serangkaian poster yang diterbitkan pada tahun 2016. Poster-poster tersebut menarik karena kata-kata di dalamnya menunjukkan proses morfologi yang kompleks dan makna tersirat yang dapat digali. Penelitian-penelitian terdahulu sebagian besar mengkaji tentang pembentukan morfologi atau telah melakukan kajian semiotika, namun belum ada yang mengaitkan proses morfologi dan gambar pada poster dengan pendekatan semiotik. Oleh karena itu, penelitian ini menganalisis proses pembentukan kata pada iklan EasyJet 2016 yang telah mengalami proses derivasi, dan mengetahui makna yang terkandung dalam iklan tersebut dengan menggunakan pendekatan semiotik. Penelitian kualitatif ini mengkaji poster-poster tersebut berdasarkan teori pembentukan kata Lehmann dan Berthet dan teori semiotika Barthes. Hasil penelitian menunjukkan bahwa dalam poster iklan ini EasyJet menarik masyarakat untuk menggunakan layanannya di beberapa segmen pasar atau kelompok konsumen sesuai dengan karakteristiknya masing-masing. Gimik yang muncul berdasarkan poster-poster ini adalah EasyJet merupakan maskapai yang ingin mengajak calon penumpangnya menjelajahi aktivitas baru

The role of charge and proton transfer in fragmentation of hydrogen-bonded nanosystems: the breakup of ammonia clusters upon single photon multi-ionization

The charge and proton dynamics in hydrogen-bonded networks are investigated using ammonia as a model system. The fragmentation dynamics of medium-sized clusters (1-2 nm) upon single photon multi-ionization is studied, by analyzing the momenta of small ionic fragments. The observed fragmentation pattern of the doubly- and triply- charged clusters reveals a spatial anisotropy of emission between fragments (back-to-back). Protonated fragments exhibit a distinct kinematic correlation, indicating a delay between ionization and fragmentation (fission). The different kinematics observed for channels containing protonated and unprotonated species provides possible insights into the prime mechanisms of charge and proton transfer, as well as proton hopping, in such a nanoscale system.Comment: 9 pages, 6 figure

INTONASI TUTURAN DEKLARATIF DAN INTEROGATIF BAHASA INDONESIA OLEH PEMELAJAR KOREA

Intonasi merupakan aspek yang perlu dikuasai pemelajar bahasa asing karena jika intonasi tidak dituturkan secara tepat, hal itu akan berakibat pada kesalahpahaman (Ur, 1999). Begitu pula pemelajar Korea yang memiliki karakterisasi prosodik tersendiri saat belajar bahasa Indonesia. Penelitian ini menginvestigasi intonasi tuturan deklaratif dan interogatif bahasa Indonesia oleh pemelajar BIPA dari Korea pada tingkat pemula, madya, dan tinggi. Data penelitian berupa tuturan tiga kalimat bahasa Indonesia. Penelitian ini menggunakan Praat untuk melihat pola intonasi dan ciri akustik ujaran. Kajian ini menunjukkan bahwa ciri akustik yang menandai ketiga tingkat pemelajar adalah kontur intonasinya. Tinggi nada hanya menandai kontras tuturan deklaratif dan interogatif. Hasil penelitian juga menunjukkan bahwa pola intonasi dan ciri akustik tuturan tingkat pemula dan madya cenderung sama dengan bahasa Korea, sementara ciri akustik tuturan tinggi cenderung sama dengan bahasa Indonesia meskipun pola intonasinya berbeda dengan bahasa Indonesia. Hal itu berkaitan dengan kurangnya porsi pengajaran intonasi di dalam kelas BIPA
