Popular Abstract in Swedish Delfiner och andra tandvalar har förmågan att ekolokalisera. Trots att dessa djur länge fascinerat människor genom historien var det först på 1950-talet som man lyckades bevisa att de faktiskt har denna förmåga. Det finns fortfarande många fundamentala frågor angående deras ekolokalisering som ännu inte besvarats, till stor del för att det har krävt alltför avancerad teToothed whales (Odontocetes) use echolocation to navigate and find food in dark or murky waters. A wide range of innovative studies has since the 1960:s been used to characterize their echolocation beam and map out their echolocation skills. In order to render high quality recordings of the sounds emitted by these animals, advanced measurement systems are required. There are still interesting env

Ventilation/perfusion single-photon emission computed tomography (V/Q SPECT) is the scintigraphic technique of choice for the diagnosis of pulmonary embolism and many other disorders that affect lung function. Data from recent ventilation studies show that the theoretic advantages of Technegas over radiolabeled liquid aerosols are not restricted to the presence of obstructive lung disease. Radiola

A Review of: Vega, Robert D. and Ruth S. Connell. “Librarians’ Attitudes Toward Conferences: A Study.” College & Research Libraries 68.6 (2007): 503-15. Objectives – To determine why professional librarians attend or do not attend conferences and to consider their attitudes toward the various conference offerings and whether conference attendance is important to their careers. Design – An e

This dissertation is concerned with the empirical and theoretical aspects of polarity item licensing in Swedish. I argue that polarity items are semantically sensitive to evaluability, a concept that refers to the possibility of accepting or rejecting a clause as true in a communicative exchange. Clauses are either evaluable or non-evaluable. According to the present hypothesis, non-evaluable clau

This study examined human listeners’ ability to classify domestic cat vocalisations (meows) recorded in two different contexts; during feeding time (food related meows) and while waiting to visit a veterinarian (vet related meows). A pitch analysis showed a tendency for food related meows to have rising F0 contours, while vet related meows tended to have more falling F0 contours. 30 listeners judg

Recension av en bok som handlar om telefonens svenska historia under 1800-talet och hur vardagsliv och tänkesätt påverkas när en ny teknologi introduceras. Författaren använder flera olika skriftliga källor, bl.a. August Strindbergs författarskap. En viss betoning på telefonen ur ett Stockholmsperspektiv.

Aortoenteric fistula formation is a devastating condition regardless of whether it is primary or secondary (i.e. after previous aneurysm repair) in nature. Patients present with signs and symptoms of gastrointestinal bleeding with or without signs of systemic infection and are often in a very poor clinical condition. Conventional treatment consists of extensive open surgery (extra-anatomical bypas

Building on previous work showing that eye gaze plays a role during moral decision-making and that the underlying mechanisms might be characterised as a fixation dependent drift-diffusion process, donation decisions between charitable organisations were studied. Models were fit with full, no or partial fixation dependence. Results indicate the model with partial fixation dependence provided the be

Highly excited 2P levels in alkali atoms were populated using a multi-step excitation, involving a tunable dye laser. The hyperfine structure of the 9 2P level in 87Rb and the 11, 12 2P levels in 133Cs was determined with optical double resonance.
