The time-domain version of the optical theorem is discussed. The theorem relates the sum of the scattered and absorbed energies, for a plane pulse that is scattered from a bounded obstacle, to the far-field amplitude in the forward direction. Several fundamental results concerning the scattered and absorbed energies that follow from the theorem are discussed.
This paper presents results from testing of a burst detection and location technique on a water transmission pipeline. The primary targets of the method are medium and large bursts that are the result of a sudden rupture of a pipe wall or other physical element in the pipeline system. The technique is based on the continuous monitoring of the pressure in the pipeline combined with a hydraulic tran
In 1982 the Swedish diplomat and philologist Gunnar Jarring (1907-2002) donated his unique collection of manuscripts from Eastern Turkestan to the University Library in Lund. It is an extremely rich collection of Eastern Turkestan manuscripts, the third largest in the world. The manuscripts come from the periphery of the Islamic world in Central Asia, nowadays the Chinese province of Xinjiang, fro
Varje förslag till forskningsprogram innebär någon form av inriktning. I denna text ligger fokus på kulturarvets plats i samhället i vid mening. Det handlar om hur företeelser, berättelser, föremål och platser produ¬ceras och används som kulturarv men också vilka kontaktytor som finns till andra politiska och sociala verksamhetsfält. Forskningsprogrammet har en betoning på möten mellan kulturarv o
Objective To investigate the effectiveness of high LET fission-neutron to induce apoptosis in murine thymocytes and to compare it with that of low LET 60Co γ-ray. Methods Apoptosis induction was studied qualitatively by light and transmission electron microscopy and DNA gel electrophoresis,also quantitatively by flow cytometry(FCM) and diphenylamine (DPA)methods. Results DNA ladders of murine thym
Varje program och kurs på Lunds universitet skall få en genuscertifieringsstämpel. Universitetets lärare skall tvingas vara genusmedvetna och bland de studerande skall det finnas en genusombudsman. Professor Tiina Rosenberg vid Centrum för genusvetenskap har initierat en ny form av kontroll och härskarteknik, skriver socialantropologen Steven Sampson.
On the European film production context with particular emphasis on Scandinavia and the regional production taking place in Ystad.
Composition of azurophil and specific granules from human polymorphonuclear neutrophils and granules from eosinophils is presented. Biosynthesis of the granule proteins is discussed in detail with particular emphasis on neutrophil myeloperoxidase (MPO) and eosinophil cationic protein (ECP).
We report results from a subset of an extensive study of the performance of blind persons in different haptic environments. Test tasks included in the study were recognition of simple geometrical objects, realistic VRML models, mathematical surfaces, a si
Immunotherapy, which involves strategies to activate, enhance or redirect immune responses to achieve long-lasting immunity, has the potential to play an important role in the treatment of a variety of diseases. This thesis, based on four original papers, highlights different approaches to modulate immune responses by specific targeting of antigen-presenting cells. The first two studies focuses o
