Although Procellariiform nestlings develop independent endothermic thermoregulation at an early age, they may not be able to meet the high energetic costs of maintaining a constant high body temperature during prolonged periods of fasting or cold exposure. The ability to reduce body temperature and enter torpor could therefore represent an important survival strategy in the Procellariiformes. It i
Villaträdgården rymmer många former av rörelse. Vissa hänger samman med årets, dygnets och livets cykler. När växtligheten spirar, myllrar det av liv och mänsklig aktivitet i trädgårdarna. Kroppar i rörelse hanterar det växande; planterar och gödslar, ansar och gallrar, gräver upp och klipper ner. Andra rörelser är långsammare; som när buskar breder ut sig och träd skjuter i höjden. En sådan långs
The aim of the paper is to give an account of a research project concerning immigrant filmmakers in Sweden from the early 1970s to the early 1990s. We have been researching the archives of the Stockholm film workshop (“Filmverkstan”) and found out at an early stage that the workshop – administered as a cooperation between the Swedish Film Institute and the Swedish broadcast organisation – turned i
Endoplasmic reticulum (ER) plays an important role in protein synthesis, folding, maturation and transport of newly synthesized proteins, as well as the regulation of cellular Ca2+ homeostasis. A protein that is involved in several of these functions in the ER is calreticulin (CRT), which is a Ca2+-binding chaperone that resides in the lumen of the ER. Animal CRT is a multifunctional protein invol
The increasing use of wireless technology utilizing unlicensed frequency bands calls for more in-depth analysis of interference and coexistence between systems. In this paper a framework is presented for detailed analysis of the performance of coexisting networks in shared frequency bands. The framework allows for multiple packet lengths to be used by the communicating devices and the analysis is
