The Bacillus subtilis hemAXCDBL gene cluster, which encodes enzymes of the biosynthetic pathway from glutamate to uroporphyrinogen III

We have recently reported (M. Petricek, L. Rutberg, I. Schroder, and L. Hederstedt, J. Bacteriol. 172:2250-2258, 1990) the cloning and sequence of a Bacillus subtilis chromosomal DNA fragment containing hemA proposed to encode the NAD(P)H-dependent glutamyl-tRNA reductase of the C5 pathway for 5-aminolevulinic acid (ALA) synthesis, hemX encoding a hydrophobic protein of unknown function, and hemC

A Data-Rate Limited View of Adaptive Control

This paper addresses the problem of adaptively controlling a plant with unknown parameters using communication-limited feedback. Assuming known dynamics, expressions have recently been obtained for the minimum average feedback data rate required for asymptotic stabilisability. The main purpose of this work is to demonstrate that this minimum rate does not increase if the plant parameters are unkno

Le réconfiguration de la culture civique

This chapter introduces the notion of civic culture as a frame for understanding political engagement and civic agency. In particular, the role of the media is underscored in shaping civic cultures; these include such dimensions as knowledge, values, practices and identities.

Coordinated voltage control in medium and low voltage distribution networks with wind power and photovoltaics

Distributed Generation (DG) installations have been increasing during the last years. Wind power and photovoltaics are two of the most common renewable energy sources for DG typically connected to the distribution network (DN) originally planned and built to supply loads. DG units connected to the DN impact the voltage where customers are connected. Network voltage is an important quality criterio

Barnets mening i LVU-processen

Ett initiativ till ett tvångsingripande enligt LVU medför att barnet hamnar i en omfattande process med avgörande betydelse för dess framtid, men där barnet självt har begränsad förmåga att hävda sina intressen. För en lagstiftning vars syfte är att tillvarata barnets intressen är de personer som utreder, presenterar och argumenterar för barnet centrala aktörer. Vilka medel använder dessa aktörer

Personal Readings and Public Texts – Book Blogs and Online Writing about Literature

The blogging culture has become an important and integrated part of the book trade and has influenced the publishing, marketing and distribution of literature in North America and in many European countries. However, it is unclear how this potential agency among bloggers operates, and thus far most research has concerned politics, media systems and larger social structures. The present article is

Passage retrieval in a question answering system.

In this paper, we describe a passage retrieval component for a questioning answering system and we evaluate its performance on Swedish documents. We used a corpus of questions and answers transcribed from the Swedish board game Kvitt eller dubbelt and, as source for the passages, we used the articles of the Swedish version of Wikipedia. We show that Wikipedia is a suitable knowledge source to answ

Demographic, Socio-Economic and Environmental Impact of AIDS in Rural Tanzania

The paper forms part of the presentation of the results from a resarch projct looking into socio-economic and environmental aspects of the HIV/ADIS epidemic. The project focuses on Tanzania with a special refernce to Karagwe and Muleba districts in Kagera Region and Makete District in Iringa Region. In this report a more aggregate level is investigated, however. In demographic terms changes in imp
