The helicity structure of the diffractive electroproduction of rho mesons, e + p --> e + rho + Y, is studied in a previously unexplored region of large four-momentum transfer squared at the proton vertex, t: 0 < t' < 3 GeV2, where t' = - min. The data used are collected with the HI detector at HERA in the kinematic domain 2.5 < Q(2) < 60 GeV2, 40 < W < 120 GeV No t dependence of the r(00)(04) spin

To mimic the electron-donor side of photosystem II (PSII), three trinuclear ruthenium complexes (2, 2 a, 2 b) were synthesized. In these complexes, a mixed-valent dinuclear moiety with one phenoxy and two acetato bridges is covalently linked to a RuII tris-bipyridine photosensitizer. The properties and photoinduced electron/energy transfer of these complexes were studied. The results show that the

This paper discusses the relation between verbal inflection and clausal structure, making the claim, based on evidence from Icelandic finite verb inflection, that formal verbal features, such as Number, Person, Tense and Mood, each represents (or corresponds to) a functional head in clausal structure. More generally, the paper claims that there is a one-to-one correspondance between formal feature

Objective: To explore the direct and Indirect costs in a cohort of 225 risperidone-treated patients with schizophrenia followed up annually during 5 years. Method: Data on costs for medication, hospitalization, sheltered living and productivity losses, as well as degree of social isolation, were collected. Results: The direct costs were dominated by hospitalization and sheltered living expenses, w

Purpose: To examine retinal function in a patient with decreased vision possibly due to treatment with methotrexate. Methods: Ophthalmological examination included testing of visual acuity (VA), fundus inspection, fundus photography and kinetic perimetry. Retinal function was tested objectively with three electrophysiological methods: full-field electroretinography (ERG), multifocal electroretino

Bode's sensitivity integral is a well-known formula that quantifies some of the limitations in feedback control for linear time-invariant systems. In this note, we show that there is a similar formula for linear time-periodic systems. The harmonic transfer function is used to prove the result. We use the notion of roll-off 2, which means that the first time-varying Markov parameter is equal to zer

There is a wide variety of ideas on democracy and democratization represented among the Indonesian democratic opposition. What is most striking is the importance of Islam as a motivation and inspiration for demands for democracy. Islam, like any other religion, can promote democratic as well as antidemocratic ideas. It is clear that the struggle for democracy in Indonesia is mainly motivated and d
