   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

   Abstract : Cooperative transmission is considered to be a key-technique for increasing the robustness, the efficiency, or the coverage of wireless communication networks. The basic concept is that the information transmission from a sender to a receiver can be aided by one or several relay nodes in a cooperative manner under constraints on power, complexity or delay.

5. 3. On capital formation and the effects of capital income taxation

   Author : Ragnar Lindgren; Handelshögskolan i Stockholm; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Abstract : How should a tax on realized capital gains be designed in order to yield the same revenue and the same impacts on savings and portfolio choice as a tax on current income? Should income from risky investments be taxed at a higher or lower rate than income from assets without risk? How is the capital structure and the dividend policy of firms determined in the presence of taxes and what are the effects of tax differentials on the debt ratio, on the dividend policy, on the capial intensity, on the willingness to take nonfinancial risks and on the welfare of workers and investors? These and related questions are analyzed in this dissertation, which uses models based on the theory of neoclassical economics and the theory of finance. As background, a comprehensive presentation is given of the theory of savings, investment and portfolio choice. READ MORE

7. 5. Nitric oxide (NO) and carbon monoxide (CO): A novel class of messenger molecules regulating insulin and glucagon secretion

   Author : Ragnar Henningsson; Institutionen för experimentell medicinsk vetenskap; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carbon monoxide CO ; nitric oxide NO ; Nitric oxide synthase NOS ; Insulin and glucagon secretion; cyclic nucleotides; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi; Heme oxygenase HO ;

   Abstract : During the last decade it has been shown that nitric oxide (NO) and carbon monoxide (CO) are produced in our own body, and that they constitute a novel class of messenger molecules. In 1992 a constitutive NO-producing NO-synthase (cNOS) was found in the islets of Langerhans, and in 1997 we could show for the first time that the islets also contained a CO-producing constitutive heme oxygenase (HO-2).
