The diversity of different life-forms, their conquest of virtually all available habitats, and their seemingly limitless ability to adapt to new ecological challenges show that structural and physiological specializations of a few basic building plans uniquely match plants and animals to the specific lives they lead.

This paper asks whether persistence can be a matter of convention. It argues that in a rather unexciting de dicto sense persistence is indeed a matter of convention, but it rejects the notion that persistence can be a matter of convention in a more substantial de re sense. However, scenarios can be imagined that appear to involve conventional persistence of the latter kind. Since there are strong

Since the early 1980s, rapidly internationalizing start-ups have captured attention of the academia, media and institutions. These ’born global’ firms seem to disregard the traditionally established views of firm internationalization. In spite of the significant resource limitations, they manage to reach international markets rapidly and keep their competitive position in the long term, running ag

Background. To characterize history, signs, and symptoms in women with a history of recurrent vulvovaginal candidosis (RVVC) and who had consulted with symptoms generally associated with the condition. Methods. Eighty-three women with a history consistent with RVVC were interviewed regarding 32 parameters and 10 signs found at the clinical examination were noted. Candida cultures were made from t

A biosensor for monitoring acetonitrile was constructed. A mixed culture was taken from a degradation reactor and mounted on top of a Clark electrode. The amperometric biosensor was placed in a flow-through cell and integrated into a flow injection system. The metabolic response in terms of oxygen consumption was well correlated to the concentration of acetonitrile in standard solutions. However,

The Anti-lock Braking System (ABS) is an important component of a complex steering system for the modern car. In the latest generation of brake-by-wire systems, the performance requirements on the ABS have changed. The controllers have to be able to maintain a specified tire slip for each wheel during braking. This thesis proposes a design model and based on that a hybrid controller that regulates

Our voices and speech behaviour give cues to the listener as to our identity. These cues make it possible for the listener to recognise a voice without seeing the speaker. A professional impersonator has to identify the salient and characteristic features of the target voice in order to succeed. The present phonetic study of a Swedish professional impersonator and one of his voice imitations compa

Iterative numerical schemes for solving the electrostatic partial differential equation with variable conductivity, using fast and high-order accurate direct methods for preconditioning, are compared. Two integral method schemes of this type, based on previously suggested splittings of the equation, are proposed, analyzed, and implemented. The schemes are tested for large problems on a square. Par

Human Legionella infections mainly consist of community-acquired and nosocomial pneumonia and rarely affect children. We describe a nosocomial infection with Legionella pneumophila, serogroup 1, subgroup OLDA, in an immunocompromized 2-y-old girl at a paediatric clinic. L. pneumophila identical to that of the patient was found in the hospital's cold-water but not in the hot-water distribution syst

Registered nurses' lived experience of preceptorship was studied in this phenomenological study. To illuminate the meaning of registered nurses' experience of being a preceptor for student nurses, individual tape-recorded interviews were conducted with 17 registered nurses. They narrated their experience of being a personal preceptor for student nurses during practical training on a hospital unit,

We introduce a new notion of independence based on the Borel-Cantelli lemma. We study this characteristic in the context of i.i.d. stochastic processes and processes driven by equilibrium dynamics.
