Recent years have seen a number of exciting developments in the evolving and expanding role of somatostatin and its analog, octreotide, in the diagnosis and treatment of cancer. It is now clear that octreotide has potential applications not just in imaging, but also in medical therapy and radiotherapy. This book contains the papers from a symposium held in September 2001 in Noordwijk in The Nether

Under en genomfattande renovering av en befintlig fortsättningskurs i hållfasthetslära har en ny examinationmetod utarbetats. Syftet med såväl hela omarbetningen av kursen som den nya examinationsmetoden, har varit att öka studenternas förmåga att göra snabba överslagsberäkningar. Studenterna delas in i grupper och varje grupp utgör en styrelse som skall ta ställning till ett designförslag. Den sn

It has been observed and reported that in pulse combustors of Helmholtz type the heat transfer is two to five times higher than expected. From experiments, where the temperature profile in the tail pipe of a pulse combustor has been measured, we have no indication why the heat transfer should be enhanced. In the tail pipe of a pulse combustor the radial component of the temperature gradient vanish

This book chapter discusses and evaluates four different efforts to extend human life: Normalize ageing, Optimize ageing, Retard ageing and postpone death, and Eliminate or overcome ageing and death. I suggest that improved treatment of disease and handicap at all ages should be welcomed. As a secondary effect, this may in many cases result in an extension of individual lives. However, the direct

The thermal effects related to wearing a bicycle helmet are complex and different studies have investigated single parts of this topic. A literature review was produced and published (Bogerd et al., 2015) summarizing the different findings to give a complete overview on this topic as well as to suggest new perspectives. Headgear increases head insulation and therefore is mainly problematic under w

Vectoring is a vital component of wideband wire- line communication systems. A disorderly leaving event (DLE) disturbs the vectoring operation since the precoder, which was designed for the channel before the change, is no longer up to date. Measurements indicate that the impact of a DLE can be serious for frequencies beyond 30 MHz, which corresponds to the band used by emerging wideband communica

Byggkostnader och boendekostnader är välkända exempel på ord som ofta ”blandas ihop”. I ” Begrepp i bygg- och fastighetssektorn” definieras och förklaras dessa och andra vanligt förekommande begrepp i bygg- och fastighetsutvecklingsprocessen. Tanken med boken är att bidra till en enklare och tydligare kommunikation i byggprocessen. Alla ord redovisas i alfabetisk ordning med förklaringar och komme

A soft output decoding algorithm for convolutional codes, yielding list sequence (LS) decoding and soft symbol output was presented. The max-log list algorithm (MLLA) was introduced, it provides near-optimum soft symbol output equal to that of the max-log MAP algorithm. It was shown that the suboptimum MLLA provides the performance-complexity tradeoff.

There has been considerable debate whether or not predators has any significant effects on prey densities in streams. This thesis examines the importance of predation in stream communities. I have conducted both field and laboratory studies where I have studied how both vertebrate and invertebrate predators affects benthic prey. Generally, predators have been found to have strong negative effects
