One of the mysteries of nebulae in the vicinity of bright stars is theappearance of bright emission spectral lines of ions, which imply fairlyhigh excitation temperatures. We suggest that an ion formationmechanism, based on resonance-enhanced two-photon ionization (RETPI) byintense H Lyman alpha radiation (wavelength of 1215 angstroms) trappedinside optically thick nebulae, can produce these spect

Denna omarbetade upplaga har likt den tidigare översatt forskningsfältet planerad kommunikation i allmänhet och hälsokommunikation i synnerhet till en pragmatiskt uppsättning riktlinjer för informatörer och planerare inom hälsoområdet.

We investigate methods for detection of rapid workload increases (load spikes) for cloud workloads. Such rapid and unexpected workload spikes are a main cause for poor performance or even crashing applications as the allocated cloud resources become insufficient. To detect the spikes early is fundamental to perform corrective management actions, like allocating additional resources, before the spi

Popular Abstract in Swedish Datorer har blivit en viktig del inom den moderna medicinen. Resultat från patientundersökningar såsom bilder, kurvor och mätvärden bearbetas ofta av datorer och presenteras sedan på ett överskådligt sätt för läkaren som grundar sitt svar på bland annat denna information. Denna doktorsavhandling beskriver hur datorn kan hjälpa till vid själva tolkningen av undersökningThe principal purposes of the studies reported in this thesis were to develop new methods to make computerised decision support systems in medicine both more reliable and fully automated. These aims were pursued in the belief that the solution to these problems will lead to an increased clinical use of such systems resulting in benefit to both patient and physician. In the first two studies, meth

In the oxyntic mucosa of the mammalian stomach, histamine is stored in enterochromaffin-like (ECL) cells and in mucosal mast cells. The activity of the histamine-forming enzyme, histidine decarboxylase (HDC), is high in ECL cells but lower in the mucosal mast cells. We studied the consequences of depleting ECL-cell histamine by continuous infusion of the HDC inhibitor a-fluoromethylhistidine (a-FM

The development of treatments based on cognitive models of worry has led to improved outcomes for adults with Generalized Anxiety Disorder (GAD), and holds out the promise that similar improvements may be achieved for GAD further down the age range. The aim of the current study was to evaluate the effect of a GAD specific,cognitive treatment in a sample of children and adolescents with GAD. Sixtee
