Integration of non-dispatchable renewable energy sources such as wind and solar into the grid is challenging due to the stochastic nature of energy sources. Hence, electrical hubs (EH) and virtual power plants that combine non-dispatchable energy sources, energy storage and dispatchable energy sources such as internal combustion generators and micro gas turbines are getting popular. However, desig

Artikeln behandlar det museala arbetet inom Kongl. Museum från 1790-talet till och med 1850-talet, med omgestaltade rum, förvärv av samlingar, konservatorernas arbete och Konstakademiens utbildning av konstnärer. Under denna period växer museiprofessionen fram, vilket utgör förutsättningen för det nya museet på Blasieholmen på 1860-talet.

An investigation on the different levels of interpretation of medieval architectural iconography. The architecture and sculpture of Lund cathedral is related to function, history, politics and religion.

PURPOSE: To investigate retinal function after reduction of intraocular pressure (IOP) by filtration surgery in patients with medically uncontrolled glaucoma. METHODS: Eleven patients (11 eyes) with medically uncontrolled glaucoma underwent trabeculectomy. Clinical investigation, visual field (testing with standard automated perimetry (SAP-Humphrey), optical coherence tomography (OCT), full-field

During the 16th century, and thus late in a european perspective, the Scandinavian language usage went from normally giving dates according to the church year calendar (each day having a name of its own, mostly referring to a saint) to normally giving them according to our modern calendar (numbering the days within each named month). The present investigation shows how this transition more exactly

Retinoic acid (RA) is an important morphogen that regulates many biological processes, including the development of the central nervous system (CNS). Its synthesis from vitamin A (retinol) occurs in two steps, with the second reaction - catalyzed by retinal dehydrogenases (RALDHs) - long considered to be crucial for tissue-specific RA production in the embryo. We have recently identified the Xenop

The article is a presentation of the basic activities of the Swedish language board during the years 1987-1998 when I was its president. New possibilities and demands opened up with the development of computer technology. At the end of the 80ies I became aware of the possible linguistic effects of globalization upon national languages like Swedish and questions of national language policy were foc

The implementation of anti-windup methods in mid-rangingcontrol needs further attention. It is demonstrated how use of standard anti-windup schemes may give unnecessary performance degradation during saturation. The problem isillustrated for two separate systems, control of oxygen concentration in a bio-reactor and temperature controlof a cooling system. In the paper, guidelines are derived for ho
