This paper summarizes recent results how to obtain approximate one-electron potentials describing exchange and correlation which depend on the local electron density. Following the lines given by Hohenberg, Kohn and Sham explicit results are given in two versions of the theory; one to describe ground state properties and one for excitation energies. The extension to spin polarized systems is discu

This paper analyzes the expected life-time utility and the hedging demands in an exchange only, representative agent general equilibrium under incomplete information. We derive an expression for the investor's expected life-time utility, and analyze his hedging demands for intertemporal changes in the stochastic unobservable growth of the endowment process and the changing quality of information r

Background: Type 2 diabetes often displays hyperlipidemia. We examined palmitate effects on pancreatic islet function in relation to FFA receptor GPR40, NO generation, insulin release, and the PPARgama agonistic thiazolidinedione, rosiglitazone. Principal findings: Rosiglitazone suppressed acute palmitate-stimulated GPR40-transduced PI hydrolysis in HEK293 cells and insulin release from MIN6c cell

Gemensamt för både direkta och indirekta el-kunder är att de konsumerar en osynlig produkt, energi. Hushållen behöver inte vara intresserade av energi eller dess ursprungskälla, men väl de tjänster som energiföretagen kan bidra till att leverera. Man köper funktionen kall öl, varmt kaffe, rena kläder, ren kopp, lyssna på radio, se på TV, medan energiföretagen säljer den immateriella tjänsten och o
